The joint spectral radius of a pair of $2\times 2$ real matrices $(A_{0},A_{1})\in M_{2}(\mathbb{R})^{2}$ is defined to be $r(A_{0},A_{1})=\limsup _{n\rightarrow \infty }\max \{\Vert A_{i_{1}}\cdots A_{i_{n}}\Vert ^{1/n}:i_{j}\in \{0,1\}\}$, the optimal growth rate of the norm of products of these matrices. The Lagarias–Wang finiteness conjecture [Lagarias and Wang. The finiteness conjecture for the generalized spectral radius of a set of matrices. Linear Algebra Appl.214 (1995), 17–42], asserting that $r(A_{0},A_{1})$ is always the $n$th root of the spectral radius of some length-$n$ product $A_{i_{1}}\cdots A_{i_{n}}$, has been refuted by Bousch and Mairesse [Asymptotic height optimization for topical IFS, Tetris heaps, and the finiteness conjecture. J. Amer. Math. Soc.15 (2002), 77–111], with subsequent counterexamples presented by Blondel et al [An elementary counterexample to the finiteness conjecture. SIAM J. Matrix Anal.24 (2003), 963–970], Kozyakin [A dynamical systems construction of a counterexample to the finiteness conjecture. Proceedings of the 44th IEEE Conference on Decision and Control, and the European Control Conference (Seville, Spain, December 2005). IEEE, Piscataway, NJ, pp. 2338–2343] and Hare et al [An explicit counterexample to the Lagarias–Wang finiteness conjecture. Adv. Math.226 (2011), 4667–4701]. In this article, we introduce a new approach to generating finiteness counterexamples, and use this to exhibit an open subset of $M_{2}(\mathbb{R})^{2}$ with the property that each member $(A_{0},A_{1})$ of the subset generates uncountably many counterexamples of the form $(A_{0},tA_{1})$. Our methods employ ergodic theory; in particular, the analysis of Sturmian invariant measures. This approach allows a short proof that the relationship between the parameter $t$ and the Sturmian parameter ${\mathcal{P}}(t)$ is a devil’s staircase.

Many multiple access techniques have been proposed and demonstrated to provide flexible solutions for FTTH network configurations. The performance of this system suffers because of the correlation properties that contribute to a high level of Multiple Access Interference (MAI), low system capacity (users), and lower transmission rate. In this paper, we have proposed Optical CDMA (OCDMA) as a configuration solution for FTTH networks to improve the performance of this type of network. Full Text: PDF References. Z. Mateusz, M.

A wavelength resolved measurement technique used in neutron imaging applications is known as energy-resolved neutron transmission imaging. This technique of reconstructing residual strain maps provides high spatial resolution measurements of strain distribution in polycrystalline materials from sets of Bragg edge measurement images. Strain field reconstructions obtained from both triangular and quadrilateral finite element meshes are compared. The reconstruction is approached via a least square method and relies on the inversion of the longitudinal ray transform, which has uniqueness issues. References B. Abbey, S. Y. Zhang, W. J. J.

The uniform scattered fields of the cylindrical wave from a parabolic surface are obtained with the theory of the boundary diffraction wave (TBDW). The non-uniform diffracted field is calculated with the regenerated vector potential and rearranged by considering the Fresnel function to obtain the uniform solution. The uniform scattered fields are calculated as the sum of the diffracted and the geometrical optic fields. The numerical analyses of the diffracted and scattered fields in both uniform and non-uniform solutions are in harmony with the literature. Full Text: PDF ReferencesBaker, B. B., Copson, E.

Chlamydia trachomatis is a bacterial pathogen that can cause serious reproductive harm. We describe a class of stochastic branching processes and their application in modelling the growth of an infection by Chlamydia. Using simulations we show that the model can reproduce biological phenomena of interest, and we show the variability in outcomes of infections under the same parameter conditions. We further speculate how this model might be used to explain long-term adverse reproductive sequelae. References Y. M. AbdelRahman and R. J. Belland. The chlamydial developmental cycle.

Titanium Grade 2 termasuk jenis bahan yang sering dipergunakan di industri, utamanya pada bahan untuk implan biomedis. Titanium Grade 2 mempunyai sifat perbandingan kekakuan terhadap berat yang baik, tahan terhadap korosi dan memiliki sifat biokompatibel yang baik di dalam tubuh. Namun memiliki konduktifitas panas yang rendah, sehingga perlu memilih perameter pemesinan yang tepat untuk menghasilkan nilai kekasaran permukaan yang baik. Penelitian ini bertujuan untuk mengetahui karakteristik Titanium Grade 2 yaitu kekasaran permukaan hasil pemesinan frais. Desain penelitian menggunakan metode Taguchi L9, dengan 2 faktor dan 3 level. Parameter pemesinan yang digunakan ialah putaran spindel 500; 700; 900 rpm dan kecepatan pemakanan 25; 50; 75 mm/menit. Variabel respon yang diteliti ialah kekasaran permukaan. Proses frais dilakukan menggunakan Mesin CNC Dahlih. Kekasaran permukaan diukur menggunakan Mitutoyo surface roughess tester. Analisis data menggunakan analisis ANOVA. Hasil penelitian menunjukan bahwa ada pengaruh variasi parameter pemesinan terhadap respon kekasaran permukaan. Variabel putaran spindel mempunyai p-value sebesar 0,039 dan variabel gerak makan memiliki p-value sebesar 0,025. Hal ini menunjukkan bahwa kedua variabel bebas tersebut memiliki pengaruh yang signifikan terhadap respon kekasaran permukaan. Kekasaran permukaan terendah dapat dicapai dengan pengaturan putaran spindel sebesar 700 rpm dan kecepatan pemakanan sebesar 25 mm/menit.

Language makes human communication possible. Apart from everyday applications, language can provide insights into individuals’ thinking and reasoning. Machine-based analyses of text are becoming widespread in business applications, but their utility in learning contexts are a neglected area of research. Therefore, the goal of the present work is to explore machine-assisted approaches to aid in the analysis of students’ written compositions. A method for extracting common topics from written text is applied to 78 student papers on technology and ethics. The primary tool for analysis is the Latent Dirichlet Allocation algorithm. The results suggest that this machine-based topic extraction method is effective and supports a promising prospect for enhancing classroom learning and instruction. The method may also prove beneficial in other applied applications, like those in clinical and counseling practice. References Blei, D. M., Ng, A. Y., & Jordan, M. I. (2003).

Abstract Background: Neurotoxicity during treatment for childhood acute lymphoblastic leukaemia (ALL) remains a significant problem. It can be acute as in methotrexate stroke-like syndrome, posterior reversible encephalopathy syndrome, or seizures, or may be subacute resulting in chronic neurocognitive defects. Symptomatic and asymptomatic neurotoxicity can affect long-term neurocognitive outcomes (e.g. attention, executive function). Worryingly, studies in patients 20-30 years post treatment suggest accelerated CNS ageing and the burden of neurological late effects may worsen over the next few decades. Thus, there is an urgent need to better understand the pathophysiology of neurotoxicity and develop ways of identifying children at risk. Previous reports suggest that treatment intensity, (particularly methotrexate exposure), age greater than 10 years and number of intrathecals may predispose to neurotoxicity but none of the studies have been sufficiently large to identify independent risk factors in multivariable analysis. In order to investigate clinical risk factors for neurotoxicity and its effect on outcomes in a large cohort of patients, we carried out a review of all neurotoxic serious adverse events (SAEs) reported for UKALL2003. Methods: Between Oct 2003 and June 2011, the UKALL2003 trial enrolled 3113 patients aged 1-24 years with ALL. The trial SAE database was interrogated for reports of seizures, encephalopathy or arachnoiditis. Cerebral venous sinus thrombosis, cerebral haemorrhage, miscellaneous encephalopathy secondary to systemic disorders and steroid psychosis (n=22) were excluded from this analysis due to their distinct aetiologies. Survival rates were calculated and compared using Kaplan Meier methods and log-rank tests. The association between neurotoxicity event and risk factors was investigated using χ2 test, univariate and multivariate logistic regression. All tests were conducted at the 5% significance level and the analyses were performed using Intercooled Stata. Results: There were 300 SAE reports of neurotoxicity in 254 patients (8.2% of all trial participants), 159 with encephalopathy, 86 with seizures and 9 other. These patients were compared to 2837 controls without any reported neurotoxicity. There was no significant difference in 5-year event-free survival, overall survival and relapse risk between the two groups. We observed a significant association between the neurotoxicity events and each of; treatment intensity, age, female sex, CNS status, T-cell immunophenotype and white cell count (Table 1). Multivariate analysis revealed that treatment allocation (regimen B/C v A, odds ratio (OR) 2.61 (95% CI 1.86-3.65), female sex (OR 1.42 (1.10-1.85), CNS status (CNS2/3/TLP v CNS1, OR 1.60 (1.14-2.24)) and age (OR 1.04 (1.01-1.07) per year) remained significant independent predictors of neurotoxicity. In order, to examine further the effect of age, we performed a stratified analysis by treatment group (regimen A v regimen B/C). Age remained significant in both groups: OR 1.15 (1.03-1.29) and 1.03 (1.01-1.06) per year, both p=0.01. Therefore, age was still a risk factor among patients receiving regimen A who were, by definition, under 10 years; despite lower methotrexate exposure. Discussion: This large study identifies treatment intensity as the main risk factor for developing acute neurotoxicity with female sex, age and CNS status having a significant modifying effect. CNS status may reflect increased intrathecal therapy given to non-CNS-1 patients. Females are more vulnerable to cranial radiotherapy induced neurotoxicity but this is the first report of female sex as a risk factor on contemporary chemotherapy treatment protocols. Reassuringly, the occurrence of acute neurotoxicity did not influence survival rates. These data provide an important benchmark for ongoing international deep phenotyping studies of chemotherapy-associated neurotoxicity.

Trace elements investigated by electron microprobe analysis (EMPA) have been combined with oxygen isotopic composition of pink, red and other colored spinels (blue, purple, brown, orange, lavender) hosted by marbles and found in placers from Luc Yen and An Phu deposits, Yen Bai province, North Vietnam. The deposits are those from Nuoc Ngap, Cong Troi, Bai Son and different placers from the An Phu area. Trace elements such as Fe-Zn-Cr-V in red and pink gem spinels permit to separate those from Cong Troi and those from the others deposits of the An Phu area. Spinels from Cong Troi have low to extremely low Zn (< 500 ppm) and high Fe contents (3,000 to 16,000 ppm) while those from An Phu area are Zn-rich (up to 11,000 ppm). Iron is the dominant element for the other colored spinels whereas Zn, Cr and V contents are extremely variable. The Bai Son blue spinel is Fe-rich (5,000 to 7,200 ppm) with some V (950 to 1,830 ppm), Cr (270 to 480 ppm), Co (240 to 400 ppm) and Ni (550 to 950 ppm). The O-isotope composition of the whole spinels ranges between 12.1 and 24.2‰ (n = 25). Within each deposit, the range of δ18O values for red, pink and colored spinels is usually similar. However, the red and pink spinels from An Phu present two distinct sets of δ18O values, respectively between 13.2 to 17.0‰ (n = 7) and 22.5< δ18O < 24.2 (n = 5). Those from Cong Troi are from 14.8 to 17.7‰ (n = 3) and their range overlaps that of An Phu. The use of O-isotopes is not useful for distinguishing between the deposits, but the low to extremely low Zn content of the Cong Trois spinels is a discriminant. The variation of δ18O values (12.1 <δ18O < 24.2‰) of the whole spinels indicates that the oxygen isotopic compositions of the metamorphic fluids were probably buffered by the local δ18O values of the impure host marbles.ReferencesChauviré B., Rondeau B., Fritsch E., Ressigeac Ph., Devidal J.-L., 2015.

Методом импедансной спектроскопии исследованы протонпроводящие свойства полисурьмяной кислоты (ПСК), допированной ионами ванадия. Для твердых растворов состава H2Sb2–xVxO6·nH2O, кристаллизующихся в структурном типе пирохлора (пр. гр. симм. Fd3m), показано, что увеличение количества ванадия в образце приводит к росту удельной протонной проводимости, которая для крайнего твердого раствора замещения H2Sb1.52V0.48O6·nH2O составляет 66 мСм/м. Из анализа данных диэлектрической спектроскопии при температурах 218–298 К определена энергия активации проводимости, которая составила 30±2 КДж/моль. Предложен механизм протонного транспорта, согласно которому в допированных ионами ванадия ПСК проводимость осуществляется посистеме водородных связей, образованных молекулами воды, расположенными в гексагональных каналах структуры типа пирохлора, и анионами кислорода октаэдра, формирующего каркас структуры REFERENCES Stenina I.

A microgravity investigation on bedrock topography was conducted at Maluri park reference level in Kuala Lumpur, Malaysia. The study aim to mapping the near-surface structure and soil and land cover distribution for geography and geophysics surveys. Two types of cross-section modeling of the residual anomaly generated the MaluriBouguer Anomaly model for site-1 and site-2 at Maluri Park. The 2D microgravity models produced the contour map, displaying the characterization due to density contrast in rock types while mapping the subsurface geological structure at different depths. Moreover, a synthetic model was initiated with the assumption of lateral distance on the left and right sides taken at 50 m and a depth of 60 m. The results of modeling confirmed that the soil and rock type composition on both models site tests are topsoil (1.1 to 1.92 g/cm3), soil (1.8 g/cm3), clay (1.63 g/cm3), gravel (1.7 g/cm3), sand (2.0 g/cm3), shale (2.4 g/cm3), sandstone (2.76 g/cm3), and limestone (2.9 g/cm3). The 2D gravity modeling using two model site tests obtained a correspondence with the observed microgravity data. Keywords: Bouguer anomaly, limestone, microgravity, soil structure, topography.

Character education in early childhood is not new, and character education is also not just a transfer of knowledge, but something that needs to be built early on through various stimula- tions. This study aims to develop the character of early childhood through audio-visual media with traditional Javanese songs. Using educational design-based research to develop audio-visual media from traditional songs, this media was tested in the field with an experimental design with a control group. Respondents involved 71 kindergarten students from one experimental class in one control class. The data revealed that character education in children shows the average value of the experi- mental class is higher than the control group, this means character education in children can be built through traditional songs. Further research can be done to improve the character of early childhood through a variety of media that interests children.

Diakses Dari: https://www.google.co.id/url?sa=t&source=web&rct=j&url=http:// Abstrak Kesehatan keuangan perusahaan merupakan salah satu faktor penting yang harus dijaga oleh perusahaan untuk mempertahankan keberlanjutan usahanya. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh dari kinerja keuangan dan tata kelola perusahaan terhadap kondisi kesehatan perusahaan. Kinerja keuangan di cerminkan oleh tiga variabel: leverage, likuiditas, dan profitabilitas. Sedangkan tata kelola perusahaan dicerminkan oleh kepemilikan manajerial, kepemilikan institusional, proporsi dewan komisaris independen, dan ukuran komite audit. Penelitian ini menggunakan laporan keuangan perusahaan manufaktur yang terdaftar di BEI tahun 2013-2017. Data dikumpulkan menggunakan metode purposive sampling. Penelitian ini menggunakan analisis regresi logistik dan hasil penelitian menemukan bahwa leverage dan kepemilikan institusional berpengaruh secara signifikan dan negatif terhadap kondisi kesehatan keuangan perusahaan yang berarti perusahaan dengan leverage dan kepemilikan institusional tinggi cenderung berada pada kondisi financial distress, sedangkan likuiditas dan profitabilitas berpengaruh signifikan dan positif terhadap kondisi kesehatan keuangan perusahaan yang berarti bahwa perusahaan dengan likuiditas dan profitabilitas tinggi akan cenderung pada kondisi finansial sehat.

In this article, reflectivity is considered as an individual general ability to develop different attitudes to life events in order to reduce an external and internal uncertainty in situations. The objective of the research is to examine the self-assessment criteria for reflectivity with psychosemantic procedure. The author designs a modified version of the Ch. Osgood’s (1957) Semantic Differential (SD) for examining the content and formal features of the self-assessment criteria of reflectivity. This study suggests two main processes of self-assessment of reflectivity, notably differentiation and integration. The results of factor analysis indicate that individuals with high reflectivity level are aligned with low differentiation of the semantic space and monolithic nature of self-assessment criteria. The coherence and consistency of self-assessment criteria reduce the individuals’ level of inner uncertainty, transform external problems to familiar tasks and increase an efficient decision-making. A high level of differentiation is related to individual readiness to make a correct decision in the situation of multiple choice. High differentiation increases the individual adjustment and prevents from poor effects of high reflectivity. Consequently, a high level of reflectivity is associated with a low level of differentiation of self-assessment criteria. References Грановская Р.М. Психология веры. Санкт-Петербург: Питер, 2010.

The objective of this work is to establish a relationship between the cutting time in rocks, determining a speed and the point load strength index test, Is (50), to characterize the rock in terms of resistance and avoid sending samples to laboratories. As a first stage, on andesite samples, 5 x 5 x 10 cm test tubes were made. After the elaboration they were subjected to cutting, using an electric floor cutter and the time was evaluated. This cut was made in a transversal way and two parts were obtained, one of them with dimensions 5 x 5 x 5 cm, approximately. In a third stage, the point load strength test was carried out in a press built for this purpose. Finally, the cutting speeds were correlated with the point load test values and only when rock samples do not pigeonhole on the proposed relationship, send them to the laboratory. Keywords: Mining fortification, uniaxial compressive strength, rock cutting, point load strength test index. References [1]P. Feijoo, R. Aucay, D.

Abstract Abstract 4991 Anti-CD20 RIT is the most effective single agent treatment for B-cell lymphoma. However, it is not widely used in community-based oncology because of perceived complexity of treatment and toxicity. We analyzed the first 48 patients treated with RIT at our institution between November 2003 and February 2011. A work sheet for referral, screening and treatment process was developed jointly between Oncology and Nuclear Medicine and a mid-level provider (MM) was designated as RIT coordinator. Pre-treatment evaluation of all patients was according to recent consensus conference report on RIT (Witzig T et al 2011) including pretreatment imaging and bone marrow (BM) aspiration and biopsy. Unless dictated by patient's renal function, bladder control status and ability to comply with post treatment radiation safety requirement, the type of RIT (Ibritumomab Tiuxetan [Zevalin®] or Iodine 131 Tositumomab [Bexxar®]) was up to the discretion of referring oncologist. For Bexxar-treated patients, dosimetry imaging was done at 48 and 120 hours; Therapy dose, on day 8, was calculated to deliver 75 cGy to the total body. Zevalin imaging (In-111) was done at 48h and therapeutic dose of 0.4mCi/kg or 0.3mCi/kg depending on platelet counts (≥150K/μL or 100–149K/ μL, respectively) on days 7, 8, or 9. Patients were monitored for toxicity (NCI-CTC v4.03) and evaluated for response after 12 weeks of therapy according to Revised Response Criteria for Malignant Lymphoma (Cheson BD et al 2007). The SPSS v19.0 program was used for statistical analysis. Median age for the whole group was 60 at diagnosis (range 34–88) and 68.5 (37-89) at RIT. There were 19 males and 29 females. All patients, except one, had relapsed or refractory disease. Twenty two patients had diffuse large B-cell lymphoma (DLBCL) and 25 had follicular lymphoma (FL) with or without transformation. Thirty four patients were treated with Bexxar and 14 were treated with Zevalin. Thirty three of 45 evaluable patients for response achieved complete (CR n=20, 44%) or partial (PR, n=13, 29%) response for overall response rate (ORR) of 73%. There was lower, but statistically not significant, ORR for DLBCL (65%) compared with FL (79%). Other factors that did not influence ORR were race, gender, type of RIT, stage of disease and BM involvement by lymphoma. There was a trend towards association between IPI score and response in DLBCL (100% ORR for scores 0–1 vs 40% for score 3). FLIPI, however, was not predictive due to the high ORR in FL. Prior therapy and response to last regimen prior to RIT (LRPtoRIT) was predictive of ORR. 100%, 79% and 47% of patients who received 1, 2, ≥3 prior regimens responded to RIT, respectively (P 0.01). 84% of patients who achieved CR or PR to LRPtoRIT responded to RIT compared with 44% of those who did not respond to LRPtoRIT (P 0.014). 87% of patients who did not receive prior external beam radiation (RT) responded to RIT compared with 43% in those who were previously treated with RT (P 0.002). Finally, patients ≤60 years of age had higher response (93%) compared with those >60 (65%) (P 0.047). Multivariate analysis showed that response to LRPtoRIT was still significant even after adjusting for age and RT prior to RIT. From Kaplan-Meier analysis, the median survival of the whole group was 48 months; 39 months for DLBCL and 82 months for FL (P 0.096). Patients who responded to RIT had a median survival of 81 months compared with those who did not (4.2 months) (P 0.000). Other factors that predicted for survival in univariate analysis were: number of prior regimens (P 0.017), response to LRPtoRIT (P 0.001), and prior external beam radiation (P 0.024). In multivariate analysis, response to RIT and response to LRPtoRIT were significant predictors of survival (P 0.048 and 0.026, respectively). There were no treatment-related deaths. Grade 3/4 toxicity was only hematologic including thrombocytopenia (38%), neutropenia (31%) and anemia (12.5%). Median time to nadir was 5, 6 and 8 weeks post therapy for platelets, neutrophils and hemoglobin, respectively. Two patients developed secondary AML and one patient developed MDS, all with complex chromosomal abnormalities. We conclude that with coordinated effort, RIT can be safely and effectively delivered in routine community setting with results comparable to those reported in clinical trials. Prior therapy and response to LRPtoRIT predict response to RIT whereas response to RIT and response to LRPtoRIT are predictive of overall survival.

Language skills are essential for early childhood, being able to speak clearly and process speech sounds, understand others, express ideas, and interact with others are the building blocks for a child's development. Therefore, this study will examine the effect of the Inside Outside Circle (IOC) instructional strategies with media images on children's language skills. This research is a quasi-experimental design with a posttest only and using a control group. The sample in this study were children in two kindergartens in the village of Banjar Tegal. Data analysis in this study was carried out by quantitative descriptive methods using t-test analysis techniques. The results of this study in kindergarten students in Banjar Tegal Village show that there is an influence of the IOC learning model with picture media on children's language skills (tcount = 6.28> ttable = 2.00). This shows that language skills achieved by groups of children participating in learning with the IOC model with drawing media are better than groups of children who attend learning without the IOC model. The implication is that further research is expected to develop other aspects of child devel- opment through the IOC model.

La fuga de clientes es un problema relevante al que enfrentan las empresas de servicios y que les puede generar pérdidas económicas significativas. Identificar los elementos que llevan a un cliente a dejar de consumir un servicio es una tarea compleja, sin embargo, mediante su comportamiento es posible estimar una probabilidad de fuga asociada a cada uno de ellos. Esta investigación aplica minería de datos para la predicción de la fuga de clientes en una empresa de distribución de gas natural, mediante dos técnicas de machine learning: redes neuronales y support vector machine. Los resultados muestran que mediante la aplicación de estas técnicas es posible identificar los clientes con mayor probabilidad de fuga para tomar sobre estas acciones de retenciónoportunas y focalizadas, minimizando los costos asociados al error en la identificación de estos clientes.

To improve online learning pedagogy within the field of paralegal education, this study investigated how paralegal students and paralegal instructors perceived the effectiveness of synchronous and asynchronous online paralegal courses. This study intended to inform paralegal instructors and course developers how to better design, deliver, and evaluate effective online course instruction in the field of paralegal studies.Survey results were analyzed using independent samples t-test and correlational analysis, and indicated that overall, paralegal students and paralegal instructors positively perceived synchronous and asynchronous online paralegal courses. Paralegal instructors reported statistically significant higher perceptions than paralegal students: (1) of instructional design and course content in synchronous online paralegal courses; and (2) of technical assistance, communication, and course content in asynchronous online paralegal courses. Instructors also reported higher perceptions of the effectiveness of universal design, online instructional design, and course content in synchronous online paralegal courses than in asynchronous online paralegal courses. Paralegal students reported higher perceptions of asynchronous online paralegal course effectiveness regarding universal design than paralegal instructors. No statistically significant differences existed between paralegal students’ perceptions of the effectiveness of synchronous and asynchronous online paralegal courses. A strong, negative relationship existed between paralegal students’ age and their perceptions of effective synchronous paralegal courses, which were statistically and practically significant. Lastly, this study provided practical applicability and opportunities for future research. Akyol, Z., & Garrison, D. R. (2008).

Seismic status in Bangladesh has been investigated using earthquake data recorded by the global network of USGS during 1980 to 2016. Seismicity parameters such as magnitude completeness Mc, b-value and a-value are being estimated. It has observed that the overall b-value in and around Bangladesh is of 0.84 which is seemed to be seismically active zone. As, reliable b-value assessment can lead to better seismic hazard analysis, reliable magnitude of completeness Mc can lead to b-value assessment of an area, this work has dealt and estimated magnitude of completeness Mc using various techniques for the whole region for a reliable estimation. Estimated Mc is obtained to be around 3.9-4.7, which lead to b-value of 0.93. Spatial variations of Mc and b-value have been investigated for 1ox1o horizontal and vertical rectangular regions for the study area between 18-29°N and 84-95°E. Estimated Mc and b-value along with b-value are then averaged for the common regions in the pair of horizontal and vertical regions. Results are then being presented in the form of maps. The findings resemble as, the Mc is low at the border line of N-W Bangladesh, and a line from Cox’s bazaar to Sylhet through Hill tracts. Remain parts belong to the Mc value of 4.1-4.2, thus the b-value obtained is varying from 0.68 to 1.2, where, the value is higher at region in Chittagong and Barisal division that extends toward north through part of Dhaka to Sylhet and lower at Rajshahi, Rangpur and part of Khulna division, while a-value is varying from 5.0 to 7.2 mostly from west to east.ReferencesAbercrombie R.E., and Brune J.N., 1994.

Rapid urbanization rates impact significantly on the nature of Land Cover patterns of the environment, which has been evident in the depletion of vegetal reserves and in general modifying the human climatic systems (Henderson, et al., 2017; Kumar, Masago, Mishra, & Fukushi, 2018; Luo and Lau, 2017). This study explores remote sensing classification technique and other auxiliary data to determine LULCC for a period of 50 years (1967-2016). The LULCC types identified were quantitatively evaluated using the change detection approach from results of maximum likelihood classification algorithm in GIS. Accuracy assessment results were evaluated and found to be between 56 to 98 percent of the LULC classification. The change detection analysis revealed change in the LULC types in Minna from 1976 to 2016. Built-up area increases from 74.82ha in 1976 to 116.58ha in 2016. Farmlands increased from 2.23 ha to 46.45ha and bared surface increases from 120.00ha to 161.31ha between 1976 to 2016 resulting to decline in vegetation, water body, and wetlands. The Decade of rapid urbanization was found to coincide with the period of increased Public Private Partnership Agreement (PPPA). Increase in farmlands was due to the adoption of urban agriculture which has influence on food security and the environmental sustainability. The observed increase in built up areas, farmlands and bare surfaces has substantially led to reduction in vegetation and water bodies. The oscillatory nature of water bodies LULCC which was not particularly consistent with the rates of urbanization also suggests that beyond the urbanization process, other factors may influence the LULCC of water bodies in urban settlements.

The paper presents research findings with 56 Roma children from Macedonia and Serbia between the ages of 3-6 years. The children’s knowledge of Romani as their mother tongue was assessed with a specially designed test. The test measures the children’s comprehension and production of different types of grammatical knowledge such as wh–questions, wh-complements, passive verbs, possessives, tense, aspect, the ability of the children to learn new nouns and new adjectives, and repetition of sentences. In addition, two pictured narratives about Theory of Mind were given to the children. The hypothesis of the authors was that knowledge of the complex grammatical categories by children will help them to understand better the Theory of Mind stories. The results show that Roma children by the age of 5 know most of the grammatical categories in their mother tongue and most of them understand Theory of Mind. References Bakalar, P. (2004).

This study aim to attempt mapping out the Land Use or Land Cover (LULC) status of Regional Project Coordination Committee (RPCC) between 2009-2019 with a view of detecting the land consumption rate and the changes that has taken place using RS and GIS techniques; serving as a precursor to the further study on urban induced variations or change in weather pattern of the cityn Rangpur City Corporation(RCC) is the main administrative functional area for both of Rangpur City and Rangpur division and experiencing a rapid changes in the field of urban sprawl, cultural and physical landscape,city growth. These agents of Land use or Land cover (LULC) varieties are responsible for multi-dimensional problems such as traffic congestion, waterlogging, and solid waste disposal, loss of agricultural land. In this regard, this study fulfills LULC changes by using Geographical Information Systems (GIS) and Remote Sensing (RS) as well as field survey was conducted for the measurement of change detection. The sources of data were Landsat 7 ETM and landsat 8 OLI/TIRS of both C1 level 1. Then after correcting the data, geometrically and radiometrically change detection and combined classification (supervised & unsupervised) were used. The study finds LULC changes built-up area, water source, agricultural land, bare soil in a change of percentage is 17.23, 2.58, -9.94, -10.19 respectively between 2009 and 2019. Among these changes, bare soil is changed to a great extent, which indicates the expansion of urban areas is utilizing the land to a proper extent.

Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, coastal salt-marches and wetlands. This paper provides a summary of the current state of knowledge of sea level-rise and its effects on both human and natural ecosystems. The focus is on coastal urban areas and low lying deltas in South-East Asia and Vietnam, as one of the most threatened areas in the world. About 3 mm per year reflects the growing consensus on the average SLR worldwide. The trend speeds up during recent decades. The figures are subject to local, temporal and methodological variation. In Vietnam the average values of 3.3 mm per year during the 1993-2014 period are above the worldwide average. Although a basic conceptual understanding exists that the increasing global frequency of the strongest tropical cyclones is related with the increasing temperature and SLR, this relationship is insufficiently understood. Moreover the precise, complex environmental, economic, social, and health impacts are currently unclear. SLR, storms and changing precipitation patterns increase flood risks, in particular in urban areas. Part of the current scientific debate is on how urban agglomeration can be made more resilient to flood risks. Where originally mainly technical interventions dominated this discussion, it becomes increasingly clear that proactive special planning, flood defense, flood risk mitigation, flood preparation, and flood recovery are important, but costly instruments. Next to the main focus on SLR and its effects on resilience, the paper reviews main SLR associated impacts: Floods and inundation, salinization, shoreline change, and effects on mangroves and wetlands. The hazards of SLR related floods increase fastest in urban areas. This is related with both the increasing surface major cities are expected to occupy during the decades to come and the increasing coastal population. In particular Asia and its megacities in the southern part of the continent are increasingly at risk. The discussion points to complexity, inter-disciplinarity, and the related uncertainty, as core characteristics. An integrated combination of mitigation, adaptation and resilience measures is currently considered as the most indicated way to resist SLR today and in the near future.References Aerts J.C.J.H., Hassan A., Savenije H.H.G., Khan M.F., 2000.

Seven spot ladybird beetle, (Coccinella septempunctata) is a widely distributed natural enemy of soft-bodied insect pests especially aphids worldwide. Both the adult and larvae of this coccinellid beetle are voracious feeders and serve as a commercially available biological control agent around the globe. Different techniques are adopted to enhance the mass rearing and storage of this natural enemy by taking advantage of its natural ability to withstand under extremely low temperatures and entering diapause under unfavorable low temperature conditions. The key objective of this study was to develop a cost effective technique for enhancing the storage life and predatory potential of the larvae of C. septempunctata through cold storage in conjunction with the use of nuclear techniques, gamma radiations. Results showed that the host eating potential of larvae was enhanced as the cold storage duration was increased. Gamma irradiation further enhanced the feeding potential of larvae that were kept under cold storage. Different irradiation doses also affected the development time of C. septempuntata larvae significantly. Without cold storage, the lower radiation doses (10 and 25 GY) prolonged the developmental time as compared to un-irradiated larvae. Furthermore, the higher dose of radiation (50GY) increased the developmental time after removal from cold storage. This study first time paves the way to use radiation in conjunction with cold storage as an effective technique in implementation of different biological control approaches as a part of any IPM programs.Key wordGamma irradiations; cold storage, Coccinella septempunctata larvae; predatory potential; integrated pest management programme.INTRODUCTIONNuclear techniques such as gamma radiations have a vast application in different programmes of biological control including continuous supply of sterilized host and improved rearing techniques (Greany and Carpenter, 2000; Cai et al., 2017). Similarly irradiation can be used for sentinel-host eggs and larvae for monitoring survival and distribution of parasitoids (Jordão-paranhos et al., 2003; Hendrichs et al., 2009; Tunçbilek et al., 2009; Zapater et al., 2009; Van Lenteren, 2012). Also, at the production level, such technique may facilitate the management of host rearing, improve quality and expedite transport of product (Fatima et al., 2009; Hamed et al., 2009; Wang et al., 2009). Gamma irradiations can also be used to stop insect’s development to enhance host suitability for their use in different mass rearing programs (Celmer-Warda, 2004; Hendrichs et al., 2009; Seth et al., 2009). Development and survival of all insects have a direct connection with temperatures which in turn affect the physical, functional and behavioral adaptations (Ramløy, 2000). Many insects living in moderate regions can survive at low temperature by process of diapause. A temperature between 0 to 10oC may cause some insects to become sluggish and they only become active when the temperature is suitable. Such insects show greater adaptations to flexible temperature regimes for better survival. Many studies have reported this concept of cold-hardiness in insects in general (Bale, 2002; Danks, 2006) and specifically in coccinellid beetles over past years (Watanabe, 2002; Koch et al., 2004; Pervez and Omkar, 2006; Labrie et al., 2008; Berkvens et al., 2010). Using this cold hardiness phenomenon, many coccinellids have been studied for the effect of cold storage such as Coccinella undecimpunctata (Abdel‐Salam and Abdel‐Baky, 2000), Coleomegilla maculata (Gagné and Coderre, 2001) and Harmonia axyridis (Watanabe, 2002). This natural phenomenon, therefore, can be a helpful tool in developing low temperature stockpiling for improving mass-rearing procedures (Mousapour et al., 2014). It may provide a significant output in terms of providing natural enemies as and when required during pest infestation peaks (Venkatesan et al., 2000). Use of irradiation in conjunction with cold storage proves to be an effective technique in implementation of different biological control approaches as a part of any IPM programme. A study reported that the pupate of house fly, Musca domestica irradiated at dose of 500 Gy and can stored up to 2 months at 6°C for future use for a parasitoid wasp Spalangia endius rearing (Zapater et al., 2009). Similarly, when irradiated at 20 GY, parasitic wasps Cotesia flavipes were stored safely up to two months without deterioration of their parasitic potential (Fatima et al., 2009). Similarly, bio-control program of sugarcane shoot borer Chilo infescatellus proved successful through the use of irradiation combined with cold storage of its egg and larval parasitoids Trichogramma chilonis and C. flavipes (Fatima et al., 2009). Less mobile life stages such as larvae are of significance in any IPM strategy because they remain on target site for more time period as compared to adults. Therefore, use of predatory larvae is very promising in different biological control approaches because of their immediate attack on pests and more resistance to unfavorable environmental conditions than delicate egg stage. In addition, with their augmentation into fields, larval stage shows their presence for longer time than adult stage and their feeding potential is also satisfactory as that of adults. For the best utilization of these predators in the field and maximum impact of 3rd and 4th larval instars on prey, we should encourage late 2nd second instar larvae of predatory beetles in the fields as these instars have more feeding capacity due to increased size and ability to handle larger preys.In spite of higher significance, there is little information available about the effect of cold storage on the survival of larval instars of different ladybird beetles and its effect on their predatory potential. Very few studies report the use of cold storage for non-diapausing larval stage like for Semiadalia undecimnotata and only one study reported the short-term storage (up to two weeks) of 2nd and 3rd instar coccinellid, C. maculate, without any loss in feeding voracity of larvae after storage (Gagné and Coderre, 2001). The survival of 3rd and 4th larval instars of C. undecimpunctata for 7 days after storage at 5oC was reported in a study but the survival rate declined after 15-60 days of storage (Abdel‐Salam and Abdel‐Baky, 2000). As C. septempunctata is considered one of the voracious predators (Afroz, 2001; Jandial and Malik, 2006; Bilashini and Singh, 2009; Xia et al., 2018) and diapause is a prominent feature of this beetle and it may undergo facultative diapause under suitable laboratory conditions (Suleman, 2015). No information is available to date about the combined effect of cold storage and irradiation on the larval instars of this species.OBJECTIVES The objective of this study was to devise a cost effective technique for the cold storage and its effect on the subsequent predatory potential of the seven spotted ladybird beetle larvae in conjunction with the use of gamma radiations. Hypothesis of the study was that an optimum length of low temperature treatment for storage purpose would not affect the predation capacity of C. septempunctata larvae and their developmental parameters including survival and pupation will remain unaffected. Furthermore, use of gamma irradiation will have some additional effects on survival and feeding capacity of irradiated C. septempunctata larvae. Such techniques can be utilized in different biocontrol programs where short term storage is required. So these larvae can be successfully imparted in different IPM programs against sucking complex of insect pests as a component of biological control strategyMATERIALS AND METHODSPlant materials: Collection and rearing of C. septempunctata: Adult C. septempunctata were collected from the wheat crop (in NIAB vicinity and farm area) in the month of March during late winter and early in spring season 2016-2017. They were kept in plastic jars and were fed with brassica aphids. Under controlled laboratory conditions (25+2oC, 16h: 8h L:D and 65+5% R.H.), eggs of C. septempuctata were obtained and after hatching, larvae were also given brassica aphids as dietary source. Larvae of second instar were selected for this experiment (as the first instar is generally very weak and vulnerable to mortality under low temperatures). As the larvae approached second instar, they were separated for the experimentation. Irradiation of larvae at different doses: Irradiation of larvae was carried out by the irradiation source 137CS at Radiation laboratory, and the larvae were then brought back to the IPM laboratory, Plant Protection Division, Nuclear Institute for Agriculture and Biology (NIAB) Faisalabad. Radiation doses of 10 GY (Grey), 25 GY and 50 GY were used to treat the second instar larvae. There were three replicates for each treatment and five larvae per replicate were used. Control treatment was left un-irradiated.Cold storage of irradiated larvae: In present work, second instar C. septempunctata larvae were studied for storage at low temperature of 8oC. The larvae were kept at 8oC for 0, I and II weeks where week 0 depicts no cold treatment and this set of larvae was left under laboratory conditions for feeding and to complete their development. For larvae that were kept under cold storage for one week at 8°C, the term week I was devised. Similarly, week II denotes the larvae that remained under cold conditions (8°C) for two continuous weeks. Larvae were removed from cold storage in their respective week i.e., after week I and week II and were left under laboratory conditions to complete their development by feeding on aphids. Data collection: For recording the predatory potential of C. septempunctata larvae, 100 aphids were provided per larva per replicate on a daily basis until pupation as this number was more than their feeding capacity to make sure that they were not starved (personal observation). Observations were recorded for survival rate, developmental time and feeding potential. Data analysis: Data were statistically analysed by Statistical Software SPSS (Version 16.0). The data were subjected to normality check through the One-sample Kolmogorov-Smirnov test. Non normal data were transformed to normal data which were then used for all parametric variance tests. One-way and two-way analyses of variance were used. For comparison between variables, LSD test at α 0.05 was applied.RESULTSFeeding potential of irradiated larvae after removal from cold storage: Results showed an increase in the feeding potential of C. septempunctata larvae with increased cold storage duration. The feeding potential was significantly higher for the larvae that spent maximum length of time (week II) under cold storage conditions followed by week I and week 0. Gamma irradiations further enhanced the feeding potential of larvae that were kept under cold storage. When larvae were irradiated at 10 GY, the eating capacity of larvae increased significantly with the duration of cold storage. Similarly, larvae that were irradiated at 25 GY, showed increase in feeding potential on aphids as the time period of cold storage increased. The feeding potential of larvae that were irradiated at 50 GY, was again significantly increased with increase of cold storage duration. When different radiation doses were compared to week 0 of storage, there was a significant difference in feeding potential and larvae irradiated at 50 GY consumed the maximum numbers of aphids when no cold storage was done followed by larvae irradiated at 10 and 25 GY. With the other treatment, where larvae were kept under cold storage for one week (week I) the larvae irradiated at 50GY again showed the highest feeding potential. The feeding potential of irradiated larvae was again significantly higher than the un-irradiated larvae that were kept for two weeks (week II) under cold storage (table 1).Two-way ANOVA was performed to check the interaction between the different radiation doses and different lengths of storage durations for feeding potential of C. septempunctata larvae on aphids. The feeding potential of larvae irradiated at different doses and subjected to variable durations of cold storage were significantly different for both the radiation doses and cold storage intervals. Furthermore, the interaction between the radiation doses and storage duration was also significant meaning that the larvae irradiated at different doses with different length of cold storage were having significant variations in feeding levels (table 2).Developmental time of irradiated larvae after removal from cold storage: Significant difference was found in the development time of the larvae of C. septempunctata when irradiated at different doses at week 0 (without cold storage). The larvae irradiated at 10 GY took the maximum time for development and with the increase in irradiation dosage, from 25 to 50 GY, the time of development was shortened. The larvae irradiated at 50 GY had the same development time as the un-irradiated ones. When, the irradiated larvae were subjected to cold storage of one week duration (week I), their development time after removal from storage condition varied significantly. The larvae irradiated at 25 GY took the maximum time for development followed by larvae irradiated at 50 GY and 10 GY. There was an indication that the development time was extended for irradiated larvae as compared to un-irradiated larvae.Results also depicted a significant difference in the time taken by irradiated larvae to complete their development after taken out from cold storage of two weeks duration (week II). As the storage time of irradiated larvae increased, the development time was prolonged. Results showed that the larvae that were irradiated at 25 and 50 GY, took the maximum time to complete their development. With the prolonged duration of cold storage up to two weeks (week II), this difference of development time was less evident at lower doses (10 GY). The larvae irradiated at 10 GY showed a significant difference in their developmental duration after being taken out of cold storage conditions of the week 0, I and II. There was no difference in the developmental duration of larvae that were un-irradiated and subjected to different regimes of storage. Un-irradiated larvae were least affected by the duration of storage. With the increase in the storage time, a decrease in the developmental time was recorded. Larvae that were irradiated at 10 GY, took the maximum period to complete their development when no cold storage was done (week 0) followed by week I and II of cold storage. When the larvae irradiated at 25 GY were compared for their development time, there was again significant difference for week 0, I and II of storage duration. Maximum time was taken by the larvae for their complete development when removed from cold storage after one week (week I). With the increase in storage duration the time taken by larvae to complete their development after removal from cold storage reduced.When the larvae were removed after different lengths of cold storage duration i.e., week 0, week I and week II, there was a significant difference in the developmental time afterwards. Results have shown that the higher dose of radiation, increased the developmental time after removal from cold storage. The larvae irradiated at 50 GY took the longest time to complete their development after removal from cold storage (week I and week II) as compared the larvae that were not kept under cold storage conditions (week 0) (table 3).Interaction between the different radiation doses and different lengths of storage durations for development time of larvae were checked by two-way ANOVA. The development time of larvae irradiated at different doses and subjected to variable durations of cold storage were significantly different for both the doses and cold storage intervals. Furthermore, the interaction between the radiation doses and storage duration was also significant meaning that the larvae irradiated at different doses with different length of cold storage were having significant variations in development times (table 4). DISCUSSIONThe present research work indicates the possibility of keeping the larval instars of C. septempunctata under cold storage conditions of 8oC for a short duration of around 14 days without affecting its further development and feeding potential. Furthermore, irradiation can enhance the feeding potential and increase the development time of larval instars. This in turn could be a useful technique in mass rearing and field release programmes for biological control through larval instars. Usually temperature range of 8-10oC is an optimal selection of low temperature for storage as reported earlier for eggs two spotted ladybird beetle, Adalia bipunctata and the eggs of C. septempunctata (Hamalainen and Markkula, 1977), Trichogramma species (Jalali and Singh, 1992) and fairyfly, Gonatocerus ashmeadi (Hymenoptra; Mymaridae) (Leopold and Chen, 2007). However, a study reported more than 80% survival rate for the coccinellid beetle, Harmonia axyridis for up to 150 days at moderately low temperature of 3-6oC (Ruan et al., 2012). So there is great flexibility in coccinellid adults and larvae for tolerating low temperature conditions. After removal from cold storage, larvae showed better feeding potential with consumption of more aphids when compared to normal larvae that were not placed under low temperature conditions. This indicates that when the adult or immature insect stages are subjected to low temperature environment, they tend to reduce their metabolic activity for keeping them alive on the reserves of their body fats and sustain themselves for a substantial length of time under such cold environment. Hereafter, the larval instars that were in cold storage were behaving as if starved for a certain length of time and showed more hunger. This behavior of improved or higher feeding potential of stored larvae has been reported previously (Chapman, 1998). Hence, the feeding potential of C. septempunctata larvae significantly increased after cold storage. Gagné and Coderre (2001) reported higher predatory efficacy in larvae of C. maculata when stored at the same temperature as in the present study i.e., 8oC. Similarly, Ruan et al. (2012) showed that the multicolored Asian ladybug, H. axyridis, when stored under cold conditions, had more eating capacity towards aphids Aphis craccivora Koch than the individuals that were not stored. Such studies indicate that the higher feeding potential in insects after being subjected to low temperature environmental conditions could be due to the maintenance of their metabolism rate to a certain level while utilizing their energy reserves to the maximum extent (Watanabe, 2002).The individuals coming out from cold storage are therefore capable of consuming more pray as they were in a condition of starvation and they have to regain their energy loss through enhanced consumption. Furthermore, the starvation in C. septempunctata has previously been reported to affect their feeding potential (Suleman et al., 2017). In the present study, the larval development was delayed after returning to normal laboratory conditions. Cold storage affects the life cycle of many insects other than coccinellids. The cold storage of green bug aphid parasitoid, Lysiphlebus testaceipes Cresson (Hymenoptra; Braconidae) mummies increased the life cycle 3-4 times. Nevertheless, in current study the development process of stored larvae resumed quickly after taking them out and larvae completed their development up to adult stage. Similar kinds of results were reported for resumption of larval development after removal from cold storage conditions. Such studies only report satisfactory survival rates and development for a short duration of cold storage but as the length of storage is increased, it could become harmful to certain insects. Gagné and Coderre (2001) reported that cold storage for longer period (three weeks) proved fatal for almost 40% of larvae of C. maculata. Furthermore, in the same study, the feeding potential of C. maculata larvae was also affected beyond two weeks of cold storage due to the loss of mobility after a long storage period. Many studies have reported that longer durations of low temperature conditions can either damage the metabolic pathways of body cells or may increase the levels of toxins within the bodies of insects. Also, low temperature exposure for longer duration may cause specific interruptions in the insect body especially neuro-hormones responsible for insect development, which could be dangerous or even life threatening.Chen et al. (2004) also reported that the biological qualities of parasitized Bemisia tabaci pupae on population quality of Encarsia formosa were affected negatively with increase in cold storage duration. Similarly, the egg hatchability of green lacewing Chrysoperla carnea Stephen was lost completely beyond 18 days of cold storage (Sohail et al., 2019). However, in the present study the cold storage was done for maximum two weeks and it is to be regarded as a short term storage hence the survival rate was satisfactory. Longer periods of cold storage for larvae are not considered safe due to their vulnerable state as compared to adults which are hardier. Also 2nd instar larvae used in the present study for cold storage for being bigger in size and physical stronger than 1st instar. Abdel‐Salam and Abdel‐Baky (2000) reported that in C. undecimpunctata the cold storage of 3rd and 4th larval instars was higher and considered safer than early larval instars. The same study showed sharp decline in survival rate after two weeks and there was no survival beyond 30-60 days of cold storage. The present study showed that short term storage of the larvae of C. septempunctata could be done without any loss of their feeding potential or development so the quality of predator remained unaffected. Similar kind of work for many other insects had been reported previously where cold storage technique proved useful without deteriorating the fitness of stored insects. For example, the flight ability of reared codling moth Cydia pomonella Linnaeus remained unaffected after removal from cold storage (Matveev et al., 2017). Moreover, a sturdy reported that pupae of a parasitoid wasp Trichogramma nerudai (Hymenoptera; Trichogrammatidae) could be safely put in cold storage for above than 50 days (Tezze and Botto, 2004). Similarly, a technique of cold storage of non-diapausing eggs of black fly Simulium ornaturm Meigen was developed at 1oC. Another study reported safe storage of a predatory bug insidious flower bug Orius insidiosus for more than 10 days at 8°C (Bueno et al., 2014).In present study without cold storage, the lower doses of 10 and 25 GY prolonged the developmental time as compared to un-irradiated larvae and higher doses of irradiations in conjunction with cold storage again significantly prolonged the developmental time of larvae when returned to the laboratory conditions. Salem et al. (2014) also reported that Gamma irradiations significantly increased the duration of developmental stages (larvae and pupae) in cutworm, Agrotis ipsilon (Hufnagel). In another study, where endoparasitic wasps Glyptapanteles liparidis were evaluated with irradiated and non-irradiated gypsy moth Lymantria dispar larvae for oviposition, it was found that non-irradiated larvae had a shorter time to reach the adult stage as compared to irradiated larvae (Novotny et al., 2003). Both for higher doses with cold storage and lower doses without cold storage extended the larval duration of C. septempunctata. In another study when the parasitoid wasp Habrobracon hebetor was irradiated at the dose of 10 GY, it resulted in prolonged longevity (Genchev et al., 2008). In the same study, when another parasitoid Ventruria canescens was irradiated at lower doses of 4GY and 3 GY, it resulted in increased emergence from the host larvae, while gamma irradiations at the dose of 1 GY and 2 GY significantly stimulated the rate of parasitism (Genchev et al., 2008). The current study also indicated higher rates of predation in the form of increased feeding potential of larvae as a result of irradiations at lower doses.CONCLUSIONThe outcome of the current study shows that storage of 2nd instar C. septempunctata at low temperature of 8oC for a short duration of about 14 days is completely safe and could have broader application in different biocontrol programs. Such flexibility in storage duration can also assist in different mass rearing techniques and commercial uses. The combination of gamma radiation with low temperature cold storage could be a useful tool in developing different biological pest management programs against sucking insect pests. Incidence of periodic occurrence of both the target insect pests with their predatory ladybird beetles in synchrony is an important aspect that could be further strengthened by cold storage techniques. Therefore, short or long term bulk cold storage of useful commercial biocontrol agents and then reactivating them at appropriate time of pest infestation is a simple but an advantageous method in mass rearing programs. Increased feeding capacity of stored larvae is another edge and hence such larvae may prove more beneficial as compared to unstored larvae. Both cold storage and improved feeding of the C. septempuctata larvae can be utilized for implementation of IPM for many sucking insect pests of various crops, fruits and vegetables. Due to some constraints this study could not be continued beyond two weeks but for future directions, higher doses and longer duration periods could further elaborate the understanding and better application of such useful techniques in future IPM programmes on a wider scale. Also, some other predatory coccinellid beetle species can be tested with similar doses and cold storage treatments to see how effective this technique is on other species as well.ACKNOWLEDGMENTS We acknowledge the Sugarcane Research and Development Board for providing a research grant (No. SRDB/P/4/16) to carry out this research work.

One of the main tasks of structural biology is comparing the structure of proteins. Comparisons of protein structure can determine their functional similarities. Multigraph alignment is a useful tool for identifying functional similarities based on structural analysis. This article proposes a new algorithm for aligning protein binding sites called ACOTS-MGA. This algorithm is based on the memetic scheme. It uses the ACO method to construct a set of solutions, then selects the best solution for implementing Tabu Search to improve the solution quality. Experimental results have shown that ACOTS-MGA outperforms state-of-the-art algorithms while producing alignments of better quality.KeywordsMultiple Graph Alignment, Tabu Search, Ant Colony Optimization, local search, memetic algorithm, SMMAS pheromone update rule, protein active sitesReferencesE.

With the development of virtual reality (VR) technology and its applications in many fields, creating simulated hands in the virtual environment is an e ective way to replace the controller as well as to enhance user experience in interactive processes. Therefore, hand tracking problem is gaining a lot of research attention, making an important contribution in recognizing hand postures as well as tracking hand motions for VR’s input or human machine interaction applications. In order to create a markerless real-time hand tracking system suitable for natural human machine interaction, we propose a new method that combines generative and discriminative methods to solve the hand tracking problem using a single RGBD camera. Our system removes the requirement of the user having to wear to color wrist band and robustifies the hand localization even in di cult tracking scenarios.

Sam bo chinh (Abelmoschus sagittifolius (Kurz) Merr.) is a precious medicinal plant that has been exploited and planted in Vietnam for a long time. However, the morphological characteristics of this plant is easy to confuse with other species of the same genus. In addition, the microscopic characteristics and medicinal powder composition of this medicinal plant have not been comprehensively described. The present investigation was aimed to determine the morphological and microscopic characters of Sam bo chinh using comparative morphology, anatomical research and medicinal powder analysis. The complete description of morphological and microscopic characteristics reported in this study will serve as valuable data for the conservation and development of this species in Vietnam.

Internet of Things (IoT) applications are increasingly making impact in all areas of humanlife. Day by day, its chatty embedded devices have been generating tons of data requiring effectivenetwork infrastructure. To deliver millions of IoT messages back and fort with as few faults aspossible, participation of communication protocols like MQTT is a must. Lightweight blueprintand friendly battery are just two of many advantages of this protocol making it become a dominantin IoT world. In real application scenarios, distributed MQTT solutions are usually required sincecentralized MQTT approach is incapable of dealing with huge amount of data. Although distributedMQTT solutions are scalable, they do not adapt to fluctuations of traffic workload. This might costIoT service provider because of redundant computation resources. This leads to the need of a novelapproach that can adapt its size changes in workload. This article proposes such an elastic solutionby proposing a flexible MQTT framework. Our MQTT framework uses off-the-shelf componentsto obtain server’s elasticity while keeping IoT applications intact. Experiments are conducted tovalidate elasticity function provided by an implementation of our framework.

This study provided an understanding of feeding habit and intensity of the mudskipper Periophthalmodon septemradiatus, which was a potential aquarium pet, by analyzing the relative gut length (RGL) andgastro-somatic (GaSI) indexes. Fish specimens were caught by fishing rods from the estuary in Soc Trang province to the upstream in An Giang province of Hau River during a period of one year from August 2017 to July 2018. Data analysis of a collection of 1,504 fishes showed that RGL did not change with fish size, resulting in the feeding habit of P. septemradiatus did not change with fish size. By contrast, the feeding habit of this mudskipper varied with place, month and season as the RGL significantly different between place, month and season, but both males and females fall into carnivorous fish as RGL was <1. Similarly, the feeding intensity of this specice did not change with fish size, as the GaSI was not significantly different among four fish size groups. Meanwhile, the mudskipper displayed spatial, temporal and seasonal variations in feeding intensity since GaSI significantly changed with place, month and season. The changes of feeding habit and intensity of P. Septemradiatus were not regulated by the interaction of fish size and place, fish size and season, and place and season. These results provided new knowledge on feeding habit and intensity of this fish specice, being used for the understanding of fish adaption and conservation in the study region.

This paper explores the effects of labour movement into nonfarm activities on household production choices in rural Vietnam. It finds that agricultural production declines and there are negative effects on farm revenue. However, these conclusions are limited in the north. Households in the north readjust their production structure by investing in livestock and other crops that require less labour. Rice farmers in the south have managed to keep their rice production unaffected by hiring more labour, and investing more capital to switch to less labour-intensive farming. The evidence of relaxing liquidity constraints is found, at least in the short run. While the decline in agricultural revenue in the north suggests some level of substitution between farming and nonfarm activities, the stability in rice production at the national level brings good news to policy makers and food security in Vietnam, despite rapid structural change over the past decades.

O processo de reparação óssea é controlado por mecanismos moleculares complexos que envolvem fatores sistêmicos e locais. Os adesivos fibrínicos, também conhecidos como selantes de fibrina ou cola de fibrina são produtos não citotóxicos, oriundos de proteínas do plasma humano, que mimetizam a via final da rede de coagulação. Os agentes antifibrinolíticos, tais como o ácido tranexâmico, inibem a fibrinólise e, conseqüentemente, impedem ou diminuem a formação dos produtos de degradação da fibrina e do fibrinogênio. O propósito deste trabalho foi avaliar histologicamente em ratos o efeito do ácido tranexâmico associado à cola de fibrina sobre o reparo ósseo. O experimento utilizou 60 (n=5) ratos machos em grupos assim constituídos: GI:Controle, GII: cola de fibrina, GIII:ácido tranexâmico e GIV: cola de fibrina/ácido tranexâmico. Defeitos ósseos (2.5mm de diâmetro) foram criados nas tíbias direitas. Os animais foram eutanasiados aos 7,14 e 30 dias pós-operatórios e as peças processadas em hematoxilina e eosina. Os resultados mostraram aos 7 dias pós-operatórios cavidade cirúrgica preenchida por tecido conjuntivo denso, rico em fibroblastos, permeado por delicadas trabéculas ósseas neoformadas, em percentual de 70-80% para GI, GII e GIII e 94.8% para GIV. Aos 14 dias pós-operatórios tecido ósseo neoformado foi encontrado entre 75-85% para GI, GII e GIII e em percentual acima de 95% para GIV. Aos 30 dias pós-operatórios GI e GIV apresentaram 95-100% de tecido ósseo maduro; GII e GIII em percentual próximo a 80-90%. Com base nos resultados obtidos e metodologia empregada conclui-se que a associação cola de fibrina/ácido tranexâmico tem ação positiva sobre a reparação óssea.Descritores: Cicatrização; Adesivo Tecidual de Fibrina; Ácido Tranexâmico.ReferênciasAbiraman S, Varma HK, Umashankar PR, John A.

Introduction In 2003 we started to write about our experience of researching and writing together. We discovered in doing so a mutuality and synergy demonstrated today by solid outcomes and a deeper friendship. Our journey has had its issues. Indeed, we have come to understand deeply the process and politics of collaboration. We started simply from a desire to become researchers, and recognised that working together was a way in which we could support each other in this mutual goal. What has surprised us is the extent to which we now participate in the process of understanding the dynamics of what collaboration means. We have been intrigued and puzzled by the synergy of our partnership. This brief article is what we would call a story of how we have come to understand the dynamic of collaboration. Defining There is considerable literature attached to collaboration that we have drawn upon in our work to date (Bond and Thompson; Dunkin; Herfnick, Messerschmitt, and Vanderick; Kyle and Mc Cutcheon; Kochen and Mullen; Lindsey; Morrison, Dobbie, and McDonald; Reamer and Bertram; Rymer; Skau; Zuckerman and Merton). Much of what we have read about collaboration rang true and confirmed our experience on many levels but it has not fully explained for us the mutuality we had experienced. The distinctions between ‘additive’ where researchers often work on discrete parts of the project and each contribute their part to the collated final product and ‘integrative’ approaches where researchers work together to develop shared understandings, often seemed to be artificial since we have found good collaboration requires both elements of addition and integration (Eisenhart and Borko). Themes in Synergy While our starting point was initially about exploring issues in our complementary disciplines within teacher education, we moved sideways to explore and research purposefully the synergy of our collaborative relationship. This resulted in the processing of our experience through the telling and writing of our story of collaboration, the analysing of that story, and the development of a framework that we thought others might find congruent: Telling our story together has enabled us to take a closer look at the process and to highlight some of the issues which we believe need to be considered before embarking on collaborative research. Telling our story was one way in which we could reflect on our current research practices and demonstrably put into action improvements (Garbett and Yourn, Collaborative Research n.pag.). The framework which we developed arose from our very first exploration of understanding our collaboration via a storytelling framework. Through McDrury and Alterio’s work we were able to distance ourselves emotionally and engage with both telling and listening. We began to link our new ideas with existing knowledge and past experiences. In looking back on our collateral outcomes we are able to see how as early career researchers we have developed ways of working that may suit others. The following themes, which form the basis of our work, are included here. A fuller version can also been found in the conference paper titled “Collaborative Research: If We Had the Time to Do It All Again, Tell Me… Would We, Could We?” that we presented at the 2003 HERDSA Conference. Table 1: Collaborative research themes Congruent research principles Establishment of ownership and equality in authorship Time management and deadlines Creating and guarding a space for collaborative work to occur within the institutional framework Critiquing our work and removing ‘selves’ from the product Respecting differences in working styles and using those to our mutual advantage Similar conceptual world view Intuition, empathy, and friendship developed as we collaborated Intrinsic and extrinsic motivating factors Including critical friends and expert others Collaboration has a life of its own and has spawned new projects The themes we provide in Table 1 are consistent with the literature and seem to encompass how we work together. Eisenhart and Borko, Fox and Faver, and Rymer provide useful lists and discuss the issues that could be taken into account when collaborating. There is not enough space here to detail all of these themes. However, they seem to fall into two main areas. These are the process of the work we do together and the reasons why we can work together so successfully. In regards to processes we have found that it is important that we are committed to managing the research through agreement and commitment. Whereas the reasons why we work so well seem to come from our mutual agreement of the way we view the world. This it seems is underpinned by our mutual respect of our differences and how we complement each other. Difficulties In the introduction we alluded to the difficulties of collaborating and here we acknowledge these do exist. For example ownership of the research is not always fully discussed and is a potential area of enormous conflict (Linsey; Smallman). We have mostly agreed that any outcomes or products would be co-authored. This, however, is problematic since authorship is described in the literature as being either hierarchical or alphabetical. What if there is acknowledged equal authorship? We struggle with the alphabetical resolution as the same person would always be second author and institutional and political measurement often delegates the second author as having a lesser role. Initially to address this issue we decided to include a statement acknowledging joint equal authorship and then began to reverse name order on alternate publications. This has been mostly well handled. We decided to focus on considering what we produced together was worth more than the ‘point’ or kudos associated with being ‘first’. However, this has not always been easy for us as the research agenda is highly politicised. We note in a paper currently in review that Kochan and Mullen replace the usual ‘and’ with ‘=’ to suggest a “new inquiry relationship symbolising genuinely equal authorship” (166). We are yet to find out whether this will be agreeable to the editorial review team of the journal. We do the same with this paper. We know that strategically, it is not just a matter of alternating our names as the academic context is not that simple. We know that the quality of the actual output and intended audience also needs consideration. We have both strategically taken first authorship in places where it would matter most for us as individuals. This has been negotiated as straight forwardly as: Shall we just do the swapsie thing…there are two articles…I’d prefer the (Higher Education) one as it will look better for me rather than the (ECE) one. (E-mail communication 22 Aug. 2003) The immediate reply was: If you want first authorship on that one—fine. I’ll get the (ECE) one although I can see that it is quite nice to diversify and not get pigeonholed. But not so bad to be thinking that you might get a name somewhere! (E-mail communication 22 Aug. 2003) As this short exchange indicates, authorship is often not discussed fully and our friendship and common courtesy means that one of us accepts second place. We would like to be resistant to the politics that surround the practice of allocating authorship but in reality, and by necessity, it continues to be source of tension. We have tried to be honest and open in dealing with this issue between ourselves. We are now working in different countries and increasingly reliant on electronic means to communicate. Our ineptness with this medium has complicated our previously easy conversations and informal visits to one another’s work spaces. We have become reliant on blunt e-mail messages although they are always tempered with some snippet of personal news. For example: How was the weekend? We were incredibly social and pranced off to lunches and afternoon teas. …I am a bit too flat out to do anymore on our stuff until Friday, is that OK? (E-mail communication 9 Sep. 2003) I meant to ring you on the weekend but the timing never seemed right. I was sure you would be out partying all night and sleeping in when I was up… Now, business…I would really like to know what the current status is of our papers. I have completely lost track so you need to fill in the details very slowly for me (E-mail communication 10 Aug. 2004) We both resort to phone calls once in a while to have ‘real time’ conversations. We have both enjoyed synchronised e-mail messages although neither of us can type as fast as we talk and the delay between sending and receiving a response is tiresome. Because of differing time zones, work commitments, and differing life styles, this is not always practicable and often the delay stretches to days. Face to face, many issues are dealt with if and when they arise. In written form, our words tend to haunt us. The following exchange, culled from our e-mail conversations, alludes to some misinterpretation which has since been deleted. I am feeling terribly conscious now that you might be feeling a bit pissed off about something that I have written that I wouldn’t have said. I actually cut and deleted quite a bit of the last e-mail because I didn’t think it would read very well. (E-mail communication 15 Feb. 2004) The reply assuaged any guilt: Hey you…I am not pissed off about anything you have said or done…nothing…I have been a bit quiet on my front but mainly as I have felt so guilty about doing nothing regarding our research (E-mail communication 16 Feb. 2004) However, this highlights the sensitivity needed to communicate effectively through the written word. It also demonstrates the craft necessary in fashioning what is hoped to be an appropriate tone. There is no doubt that our friendship, empathy, and willingness more than often defines how we understand our mutuality and frame communication. An Ending The focus for this discussion has been to provide a brief look into our collaboration and go in some part to explain the synergistic relationship of mutuality for our outcomes and our deepening professional and personal regard. We have also included some detail of the difficulties associated with authorship and even now, after some years of working in this manner, our inability to discuss this properly. We are currently working on different continents and, recognising that distance is our enemy, we are seeking new ways of working together as we recognise the value in our work with each other. We agree with the statement by Kochan and Mullen that it is possible for an ‘ethic’ of collaboration to be developed where we as women are creating our own “value system, which honours collaboration that helps keep us afloat during difficult times” (161). It is an ongoing negotiation and the story it seems, for us, is yet to find its end. Our Work Together Garbett, D., and B.

This paper uses the model of experimental mouse liver damage with paracetamol to evaluate the liver protective effects of the methanol extract (Colocasia esculenta (L.) Schott) (MCE). After 8 days, the hepatoprotective activities of MCE in mice (damaged by paracetamol) at doses of 500, 1,000 and 2,000 mg/kg/day proved effective as the AST enzyme content decreased by 6.98, 22.84 and 26.59%, respectively; and ALT decreased by 53.17, 56.46 and 57.93%, respectively. MCE at a dose of 1,000 mg/kg/day had a protective effect equivalent to that of silymarin (used in liver treatment) at a dose of 50 mg/kg/day and MCE at a dose of 2,000 mg/kg/day had better effect. Observation of the microscopic liver tissue cross section also revealed that the mice treated with MCE of C. esculenta at doses of 1,000 and 2,000 mg/kg/day showed significantly improvement in their liver tissues compared to the non-treated control group.

Apolipoprotein C3 (APOC3) plays an important role in regulating lipid levels. This study aimed to assess whether the polymorphism APOC3-rs2854116 is associated with lipid profiles in primary school children in Hanoi. A case-control study was designed including 161 cases with dyslipidemia and 406 controls without dyslipidemia. Genotype for APOC3-rs2854116 polymorphism was determined by the polymerase chain reaction and restriction fragment length polymorphism method (PCR-RFLP). The results showed that there were differences in the effect of APOC3-rs2854116 polymorphism to lipid profiles among children with dyslipidemia. In comparison with A/G and A/A carriers, the G/G carriers had the higher concentration of serum TC, TG, and LDL-C (P < 0.05). APOC3-rs2854116 polymorphism was related to hypercholesterolemia in children with the most appropriate genetic model being additive model. Increasing each of the G alleles increased the risk of hypercholesterolemia by 2.2 times (P = 0.005) after adjustment for age and sex. This relationship was almost unchanged after adjustment for obesity-related traits. The study suggested that the APOC3-rs2854116 polymorphism significantly associated with hypercholesterolemia in primary school children in Hanoi independent of obesity-related traits. Keywords APOC3, rs2854116, hypercholesterolemia, primary school children. References [1] A. Kawakami, M.

The variable 'genre' aims to identify and compare different types of games, mainly in terms of gameplay differences (i.e., rules and players’ possibilities to interact with a game). Genre is usually coded by using external video game databases, such as those published on journalistic websites. Field of application/theoretical foundation: The variable ‘genre’ is often used in content analyses of video games to identify and compare different types of games. Lynch et al (2016), for example, investigate whether the number of sexualized characters differ between various video game genres (Action, Adventure, Fighting, Platformer, Role-Playing-Game, Shooter). However, the definition and validity of different genre lists is controversially discussed in the literature (e.g., Arsenault, 2009). Most content analytic studies adopt the value of the genre variable for a given game from an external source. Most commonly, scholars use one or more databases published on journalistic video game websites (www.ign.com; www.gamespot.com; www.giantbomb.com), on Wikipedia or the database of the Entertainment Software Rating Board (www.esrb.org). Most of the genre classifications in these databases are based on gameplay characteristics rather than narrative themes. For example, both the game Starcraft as well as Anno 1602 are classified as ‘real-time strategy’ on Wikipedia, regardless of the fact that they have rather different settings (science fiction vs. historic). To ensure that games are classified into a few, clear genre categories (some journalistic genre lists are extremely detailed, see Arsenault, 2009), many content analyses define potential values of the genre variable in a first step (see below). For example, while IGN (www.ign.com) currently categorizes games in 27 different genre categories, studies mostly only differentiate between 9-15 genres (see below). In a second step, the appropriate value of the variable for a given game is coded based on the external sources. Additionally, rules need to be developed that determine how to deal with potential conflicts. At first, if coding is based on multiple sources, it needs to be decided how to deal with potential conflicts between these sources. For example, Hanninger and Thompson (2004) report that “the genre most frequently used” (p. 867) was coded in such cases. In contrast, Lynch and colleagues (2016) prioritized entries in the IGN database and only used additional sources (GiantBomb and Wikipedia) if information was lacking. Moreover, scholars need to decide how to deal with multiple categorizations of a given game in the same database (e.g. Anno 1602 is classified as ‘real-time strategy’ and ‘city-building game’ on Wikipedia). Lynch and colleagues (2016), for instance, coded the first genre from their list which was mentioned in the database. Finally, scholars must also ensure that their shortened list of genres (step 1) is consistent with the potentially more detailed classification approach of external databases or develop a scheme that defines the correspondence between these lists. References/combination with other methods of data collection: Scholars may also use survey methods to classify games in homogeneous groups. For example, experts or players could be asked to evaluate several games on multiple dimensions, such as setting and gameplay mechanics. Subsequent statistical cluster analysis (e.g., hierarchical clustering) could be applied to identify homogeneous groups of games. Moreover, games could be clustered on the basis of their textual descriptions, for example, in Wikipedia articles. Automated methods, such as latent semantic analysis, can be used for this purpose (e.g. Ryan et al., 2015).

Abstract: This study examines the effect of substituted concentration on the structure and magnetic properties of Y3Fe5-xInxO12 (x = 0.1 ÷ 0.7) powder samples prepared using the sol-gel method. The morphological properties of the samples were analysed using XRD, SEM. The single phase of garnet was obtained in x = 0.1 ÷ 0.6 samples. The lattice parameters of the samples exhibit a linear increase with the increasing In3+ content, which can be explained by a substitution of In3+ ions for Fe3+ ions, considering the larger ionic radius of In3+ compared with that of Fe3+. Crystallite sizes were determined via the XRD data which are of 38 – 49 nm while the particle sizes were estimated from SEM images to be in range of 50 - 100 nm. Magnetization and Curie temperature of the single phase samples were studied by magnetization curves in fields up to 10 kOe and in the temperature range from 80 K to 560K. With the increase of In3+, the magnetization gradually increases while the Curie temperature decreases due to the occupation of In atoms at the a sites and the reduction of intersublattice interaction, respectively.

Panax L. is a small genus in the Araliaceae family. In Vietnam, this genus is distributed in the high mountains in the North and in some high mountains in the Central Highlands. In traditional medicine, roots and rhizomes of all Panax species are of high utility. Recently, the finding of new distributions of some Panax species in Vietnam has caused much controversy and confusion. This study investigates 27 fresh specimens of 6 taxa of Panax genus that have been collected from 6 provinces of Vietnam. Based on the combined ITS-rDNA and matK dataset, a well-resolved phylogeny of Panax species/varieties distributed in Vietnam was constructed. Thereby, the study suggests identifying Tam that la xe as Panax stipuleanatus H.T.Tsai et K.M.Feng and Sam puxailaileng as Panax vietnamensis var. fuscidiscus K.Komatsu, S.Zhu & S.Q.Cai, which contributes a new distribution point of this variety in Vietnam. The study also shows that ITS-rDNA and matK genes are highly potential in identifying and distinguishing the taxa of Panax genus.

Jamming culture has become associated with digital manipulation and reuse of materials. As well, the term jamming has long been used by musicians (and other performers) to mean improvisation, especially in collaborative situations. A practice that gets to the heart of both these meanings is live coding; where digital content (music and/or visuals predominantly) is created through computer programming as a performance. During live coding performances digital content is created and presented in real time. Normally the code from the performers screen is displayed via data projection so that the audience can see the unfolding process as well as see or hear the artistic outcome. This article will focus on live coding of music, but the issues it raises for jamming culture apply to other mediums also. Live coding of music uses the computer as an instrument, which is “played” by the direct construction and manipulation of sonic and musical processes. Gestural control involves typing at the computer keyboard but, unlike traditional “keyboard” instruments, these key gestures are usually indirect in their effect on the sonic result because they result in programming language text which is then interpreted by the computer. Some live coding performers, notably Amy Alexander, have played on the duality of the keyboard as direct and indirect input source by using it as both a text entry device, audio trigger, and performance prop. In most cases, keyboard typing produces notational description during live coding performances as an indirect music making, related to what may previously have been called composing or conducting; where sound generation is controlled rather than triggered. The computer system becomes performer and the degree of interpretive autonomy allocated to the computer can vary widely, but is typically limited to probabilistic choices, structural processes and use of pre-established sound generators. In live coding practices, the code is a medium of expression through which creative ideas are articulated. The code acts as a notational representation of computational processes. It not only leads to the sonic outcome but also is available for reflection, reuse and modification. The aspects of music described by the code are open to some variation, especially in relation to choices about music or sonic granularity. This granularity continuum ranges from a focus on sound synthesis at one end of the scale to the structural organisation of musical events or sections at the other end. Regardless of the level of content granularity being controlled, when jamming with code the time constraints of the live performance environment force the performer to develop succinct and parsimonious expressions and to create processes that sustain activity (often using repetition, iteration and evolution) in order to maintain a coherent and developing musical structure during the performance. As a result, live coding requires not only new performance skills but also new ways of describing the structures of and processes that create music. Jamming activities are additionally complex when they are collaborative. Live Coding performances can often be collaborative, either between several musicians and/or between music and visual live coders. Issues that arise in collaborative settings are both creative and technical. When collaborating between performers in the same output medium (e.g., two musicians) the roles of each performer need to be defined. When a pianist and a vocalist improvise the harmonic and melodic roles are relatively obvious, but two laptop performers are more like a guitar duo where each can take any lead, supportive, rhythmic, harmonic, melodic, textual or other function. Prior organisation and sensitivity to the needs of the unfolding performance are required, as they have always been in musical improvisations. At the technical level it may be necessary for computers to be networked so that timing information, at least, is shared. Various network protocols, most commonly Open Sound Control (OSC), are used for this purpose. Another collaboration takes place in live coding, the one between the performer and the computer; especially where the computational processes are generative (as is often the case). This real-time interaction between musician and algorithmic process has been termed Hyperimprovisation by Roger Dean. Jamming cultures that focus on remixing often value the sharing of resources, especially through the movement and treatment of content artefacts such as audio samples and digital images. In live coding circles there is a similarly strong culture of resource sharing, but live coders are mostly concerned with sharing techniques, processes and tools. In recognition of this, it is quite common that when distributing works live coding artists will include descriptions of the processes used to create work and even share the code. This practice is also common in the broader computational arts community, as evident in the sharing of flash code on sites such as Levitated by Jared Tarbell, in the Processing site (Reas & Fry), or in publications such as Flash Maths Creativity (Peters et al.). Also underscoring this culture of sharing, is a prioritising of reputation above (or prior to) profit. As a result of these social factors most live coding tools are freely distributed. Live Coding tools have become more common in the past few years. There are a number of personalised systems that utilise various different programming languages and environments. Some of the more polished programs, that can be used widely, include SuperCollider (McCartney), Chuck (Wang & Cook) and Impromptu (Sorensen). While these environments all use different languages and varying ways of dealing with sound structure granularity, they do share some common aspects that reveal the priorities and requirements of live coding. Firstly, they are dynamic environments where the musical/sonic processes are not interrupted by modifications to the code; changes can be made on the fly and code is modifiable at runtime. Secondly, they are text-based and quite general programming environments, which means that the full leverage of abstract coding structures can be applied during live coding performances. Thirdly, they all prioritise time, both at architectural and syntactic levels. They are designed for real-time performance where events need to occur reliably. The text-based nature of these tools means that using them in live performance is barely distinguishable from any other computer task, such as writing an email, and thus the practice of projecting the environment to reveal the live process has become standard in the live coding community as a way of communicating with an audience (Collins). It is interesting to reflect on how audiences respond to the projection of code as part of live coding performances. In the author’s experience as both an audience member and live coding performer, the reception has varied widely. Most people seem to find it curious and comforting. Even if they cannot follow the code, they understand or are reassured that the performance is being generated by the code. Those who understand the code often report a sense of increased anticipation as they see structures emerge, and sometimes opportunities missed. Some people dislike the projection of the code, and see it as a distasteful display of virtuosity or as a distraction to their listening experience. The live coding practitioners tend to see the projection of code as a way of revealing the underlying generative and gestural nature of their performance. For some, such as Julian Rohrhuber, code projection is a way of revealing ideas and their development during the performance. “The incremental process of livecoding really is what makes it an act of public reasoning” (Rohrhuber). For both audience and performer, live coding is an explicitly risky venture and this element of public risk taking has long been central to the appreciation of the performing arts (not to mention sport and other cultural activities). The place of live coding in the broader cultural setting is still being established. It certainly is a form of jamming, or improvisation, it also involves the generation of digital content and the remixing of cultural ideas and materials. In some ways it is also connected to instrument building. Live coding practices prioritise process and therefore have a link with conceptual visual art and serial music composition movements from the 20th century. Much of the music produced by live coding has aesthetic links, naturally enough, to electronic music genres including musique concrète, electronic dance music, glitch music, noise art and minimalism. A grouping that is not overly coherent besides a shared concern for processes and systems. Live coding is receiving greater popular and academic attention as evident in recent articles in Wired (Andrews), ABC Online (Martin) and media culture blogs including The Teeming Void (Whitelaw 2006). Whatever its future profile in the boarder cultural sector the live coding community continues to grow and flourish amongst enthusiasts. The TOPLAP site is a hub of live coding activities and links prominent practitioners including, Alex McLean, Nick Collins, Adrian Ward, Julian Rohrhuber, Amy Alexander, Frederick Olofsson, Ge Wang, and Andrew Sorensen. These people and many others are exploring live coding as a form of jamming in digital media and as a way of creating new cultural practices and works.

Artistic collaboration involves a certain loss of self, because it arises out of the merging of participants. In this sense collaboration questions the notion of the creative individual and the myth of the isolated artistic genius. As such, artistic collaborations can be subversive interventions into the concept of authorship and the ideologies that surround it (Smith 189-194). Collaborations also often simultaneously superimpose many different approaches to the collaborative process. Collaboration is therefore a multiplicitous activity in which different kinds of interactivity are interlinked; this process may also be facilitated by improvisation which allows for continuous modification of the interactions (Smith and Dean, Improvisation). Even when we are writing individually, we are always collaborating with prior texts and employing ideas from others, advice and editing suggestions. This eclectic aspect of creative work has led some to argue that collaboration is the dominant mode, while individual creativity is an illusion (Stillinger; Bennett 94-107). One of the reasons why collaboration tends to be multiplicitous is that contemporary creative endeavour sometimes involves collaboration across different media and with computers. Artworks are created by an ‘assemblage’ of different expertises, media, and machines in which the computer may be a ‘participant’. In this respect contemporary collaboration is what Katherine Hayles calls posthuman: for Hayles ‘the posthuman subject is an amalgam, a collection of heterogeneous components, a material-informational entity whose boundaries undergo continuous construction and reconstruction (Hayles 3). Particularly important here is her argument about the conceptual shifts that information systems are creating. She suggests that the binary of presence and absence is being progressively replaced in cultural and literary thought by the binary of pattern and randomness created by information systems and computer mediation (Hayles 25-49). In other words, we used to be primarily concerned with human interactions, even if sometimes it was the lack of them, as in Roland Barthes concept of ‘the death of the author’. However, this has shifted to our concern with computer systems as methods of organisation. Nevertheless, Hayles argues, computers can never totally replace embodied human subjects, rather we need to continually negotiate between presence and pattern, absence and randomness (Hayles 25-49). This very negotiation is central to many computer-mediated collaborations. Our own collaborative practice—Roger is primarily a musician and Hazel primarily a writer but we both have interdisciplinary performance and technological expertise—spans 15 years and has resulted in approximately 18 collaborative works. They are all cross-media: initially these brought together word and sound; now they sometimes also include image. They all involve multiple forms of collaboration, improvised and unfixed elements, and computer interfaces. Here we want to outline some of the stages in the making of our recent collaboration, Time, the Magician, and its ‘posthuman’ engagement with computerised processes. Time, the Magician is a collaborative performance and sound-video piece. It combines words, sound and image, and involves composed and improvised elements as well as computer mediation. It was conceived largely by us, but the first performance, at the Sydney Conservatorium of Music in 2005 also involved collaboration with Greg White (sound processing) and Sandy Evans (saxophone). The piece begins with a poem by Hazel, initially performed solo, and then juxtaposed with live and improvised sound. This sound involves some real-time and pre-recorded sampling and processing of the voice: this—together with other sonic materials—creates a ‘voicescape’ in which the rhythm, pitch, and timbre of the voice are manipulated and the voice is also spatialised in the performance space (Smith and Dean, “Voicescapes”). The performance of the poem is followed (slightly overlapping) by screened text created in the real-time image-processing program Jitter, and this is also juxtaposed with sound and voice samples. One of the important aspects of the piece is its variability: the video-manipulated text and images change both in order and appearance each time, and the sampling and manipulation of the voice is different too. The example here shows short extracts from the longer performance of the work at the Sydney 2005 event. (This is a Quicktime 7 compressed video of excerpts from the first performance of Time, the Magician by Hazel Smith and Roger Dean. The performance was given by austraLYSIS (Roger Dean, computer sound and image; Sandy Evans, saxophone; Hazel Smith, speaker; Greg White, computer sound and sound projection) at the Sydney Conservatorium of Music, October 2005. The piece in its entirety lasts about 11 minutes, while these excerpts last about four minutes, and are not cross-faded, but simply juxtaposed. The piece itself will later be released elsewhere as a Web video/sound piece, made directly from the sound and the Jitter-processed images which accompany it. This Quicktime 7 performance video uses AAC audio compression (44kHz stereo), H.264 video compression (320x230), and has c. 15fps and 200kbits/sec.; it is prepared for HTTP fast-start streaming. It requires the Quicktime 7 plugin, and on Macintosh works best with Safari or Firefox – Explorer is no longer supported for Macintosh. The total file size is c. 6MB. You can also access the file directly through this link.) All of our collaborations have involved different working processes. Sometimes we start with a particular topic or process in mind, but the process is always explorative and the eventual outcome unpredictable. Usually periods of working individually—often successively rather than simultaneously—alternate with discussion. We will now each describe our different roles in this particular collaboration, and the points of intersection between them. Hazel In creating Time, the Magician we made an initial decision that Roger—who would be responsible for the programming and sound component of the piece—would work with Jitter, which we had successfully used for a previous collaboration. I would write the words, and I decided early on that I would like our collaboration to circle around ideas—which interested both Roger and me—about evolution, movement, emergence, and time. We decided that I would first write some text that would then be used as the basis of the piece, but I had no idea at this stage what form the text would take, and whether I would produce one continuous text or a number of textual fragments. In the early stages I read and ‘collaborated with’ a number of different texts, particularly Elizabeth Grosz’s book The Nick of Time. I was interested in the way Grosz sees Darwin’s work as a treatise on difference—she argues that for Darwin there are no clear-cut distinctions between different species and no absolute origin of the species. I was also stimulated by her idea that political resistance is always potential, if latent, in the repressive regimes or social structures of the past. As I was reading and absorbing the material, I opened a file on my computer and—using a ‘bottom-up’ approach—started to write fragments, sometimes working with the Grosz text as direct trigger. A poem evolved which was a continuous whole but also discontinuous in essence: it consisted of many small fragments that, when glued together and transformed in relation to each other, reverberated though association. This was appropriate, because as the writing process developed I had decided that I would write a poem, but then also disassemble it for the screened version. This way Roger could turn each segment into a module in Jitter, and program the sequence so that the texts would appear in a different order each time. After I had written the poem we decided on a putative structure for the work: the poem would be performed first, the musical element would start about halfway through, and the screened version—with the fragmented texts—would follow. Roger said that he would video some background material to go behind the texts, but he also suggested that I design the texts as visual objects with coloured letters, different fonts, and free spatial arrangements, as I had in some previous multimedia pieces. So I turned the texts into visual designs: this often resulted in my pulling apart sentences, phrases and words and rearranging them. I then converted the texts files into jpg files and gave them to Roger to work on. Roger When Hazel gave me her 32 text images, I turned these into a QuickTime video with 10 seconds per image/frame. I also shot a 5 minute ‘background’ video of vegetation and ground, often moving the camera quickly over blurred objects or zooming in very close to them. The video was then edited as a continually moving sequence with an oscillation between clearly defined and abstracted objects, and between artificial and natural ones. The Jitter interface is constructed largely as a sequence of three processing modules. One of these involves continuously changing the way in which two layers (in this case text and background) are mixed; the second, rotation and feedback of segments from one or both layers; and the third a kind of dripping across the image, with feedback, of segments from one or both layers. The interface is performable, in that the timing and sequence can be altered as the piece progresses, and within any one module most of the parameters are available for performer control—this is the essence of what we call ‘hyperimprovisation’ (Dean). Both text and image layers are ‘granulated’: after a randomly variable length of time—between 2 and 20 seconds or so—there is a jump to a randomly chosen new position in the video, and these jumps occur independently for the two layers. Having established this approach to the image generation, and the overall shape of the piece (as defined above), the remaining aspects were left to the creative choices of the performers. In the Sydney performance both Greg White and I exploited real-time processing of the spoken text by means of the live feed and pre-recorded material. In addition we used long buffers (which contained the present performance of the text) to access the spoken text after Hazel had finished her performed opening segment. I worked on the sound and speech components with some granulation and feedback techniques, throughout, while Greg used a range of other techniques, as well as focusing on the spatial movement of the sound around four loudspeakers surrounding the performance and listening space. Sandy Evans (saxophone)—who was familiar with the overall timeline—improvised freely while viewing the video and listening to our soundscape. In this first performance, while I drove the sound, the computer ‘posthumanly’ (that is without intervention) drove the image. I worked largely with MSP (Max Signal Processing), a part of the MAX/MSP/Jitter suite of platforms for midi, sound and image, to complement sonically the Jitter-mediated video. So processes of granulation, feedback, spatial rotation (of image) or redistribution (of sound)—as well as re-emergence of objects which had been retained in the memory of the computer—were common to both the sound and image manipulation. There was therefore a degree of algorithmic synaesthesia—that is shared algorithms between image and sound (Dean, Whitelaw, Smith, and Worrall). The collaborative process involved a range of stimuli: not only with regard to those of process, as discussed, but also in relation to the ideas in the text Hazel provided. The concepts of evolution, movement, and emergence which were important to her writing also informed and influenced the choice of biological and artificial objects in the background video, and the nature and juxtaposition of the processing modules for both sound and image. Conclusion If we return to the issues raised at the beginning of this article, we can see how our collaboration does involve the merging of participants and the destabilising of the concept of authorship. The poem was not complete after Hazel had written it—or even after she had dislocated it—but is continually reassembled by the Jitter interface that Roger has constructed. The visual images were also produced first by Hazel, then fused with Roger’s video in continuously changing formations through the Jitter interface. The performance may involve collaboration by several people who were not involved in the original conception of the work, indicating how collaboration can become an extended and accumulative process. The collaboration also simultaneously superimposes several different kinds of collaborative process, including the intertextual encounter with the Grosz text; the intermedia fusion of text, image and sound; the participation of a number of different people with differentiated roles and varying degrees of input; and collaboration with the computer. It is an assemblage in the terms mentioned earlier: a continuously modulating conjunction of different expertises, media, and machines. Finally, the collaboration is simultaneously both human and posthuman. It negotiates—in the way Hayles suggests—between pattern, presence, randomness, and absence. On the one hand, it involves human intervention (the writing of the poem, the live music-making, the shooting of the video, the discussion between participants) though sometimes those interventions are hidden, merged, or subsumed. On the other hand, the Jitter interface allows for both tight programming and elements of variability and unpredictability. In this way the collaboration displaces the autonomous subject with what Hayles calls a ‘distributed system’ (Hayles 290). The consequence is that the collaborative process never reaches an endpoint: the computer interface will construct the piece differently each time, we may choose to interact with it in performance, and the sound performance will always contain many improvised and unpredictable elements. The collaborative process, like the work it produces, is ongoing, emergent, and mutating. References Bennett, Andrew. The Author. London: Routledge, 2005. Dean, Roger T.

Following the deep-seated analogy between biological and computer parasites, it is surely inconceivable that anyone would want to deliberately infect a computer. It’s a bad idea, right? Well, not necessarily. It seems that the University of Calgary (UoC) want to challenge the received wisdom of security experts—a judgment, which determines that there is no such thing as a good virus. The UoC wants to encourage their students to write and test malevolent viruses. Still following the biological analogy, Dr John Aycock, the academic who runs the program at UoC, likens the approach to ‘what medical researchers do to combat the latest biological viruses such as Sars’. He argues that ‘before you can develop a cure, you have to understand what the virus is and how it spreads and what motivates those who write malicious software’ (Fried). The reaction from security experts is not surprisingly one of dismay—for them, all viruses are bad. Nonetheless, it is Dr. Aycock’s provocation that may provide a much-needed alternative solution to one of the biggest problems facing the network society. As many affiliates of this composite society are increasingly discovering, the network is a present day communication paradox. It is a vast, fast, and efficient logic machine, but simultaneously it provides the perfect medium for viral contagion. Moreover, despite the efforts of a billion dollar anti-virus industry, current reactive solutions are clearly not working. A report in the UK (DTI) concludes that despite the considerable uptake of anti-virus software—93% of UK companies have anti-virus software—70% of all security breaches are from viral-like programs. (The DTI report claims that ‘two-thirds of organisations that had any security incident said that a virus infection was their worst one’. In comparison, a 1991 Gallup survey [in Louw and Duffy] showed that of 500 of the UK’s largest businesses 24% had experienced a viral attack.) Viruses, it seems, are progressively more capable of ‘bypassing traditional anti-virus software and targeting vulnerabilities’. However, Dr Aycock argues that academics should not bury their heads in the sand. They should openly recognise that ‘reacting to the virus is simply not working’ and instead support pro-active research into the creation of computer viruses. Within the bad idea itself there maybe a good solution. Naturally, the experts are outraged by what they perceive as an incursion beyond the ethical norms of the computer world. These recent events are part of an ongoing good virus/bad virus debate. Network controllers have long argued for the ethical containment of viral code. Unlocking the secrets of the virus writer is, according to the anti-virus community, a bad idea. In the early 1980s, when Fred Cohen began experimenting with self-replicating code as part of his PhD, he experienced the moral indignation of the computer community. Cohen’s viral research at the University of Southern California (USC) referenced von Neumann’s seminal work on cellular automata (1948) and the Darwinian computer games played out in the Bell Labs in the 1950s and 1960s (Dewdney). Cohen was working on a similar, but simplified, idea, a ‘program’ that could insert itself into other programs and assume control of them. In doing so, he quickly realised the potential problem of the computer virus. I’d been working on computer security for a long time – I knew how systems worked, and how different attacks worked… But it came over me. Anyone who writes one of these things would have something that could replicate everywhere (Spiller 172). After seeing the results of his experiments, network controllers at USC banned him from repeating any similar exercises. Moreover, after completing his thesis in 1985, he could not get it published in a journal until 1987 (Spiller 176; it was finally published in the journal Computers and Security), and suffered a ‘virtual lockout’ in the funding of further research. Cohen later refers to the ‘apparent fear reaction’ as a result of trying to solve technical problems with policy solutions. At the time, Cohen used the same biological analogy as Dr. Aycock to defend his research into computer viruses. The benefits of biological research on the quality of life is indisputable, and the benefits of computer virus research may some day pay off in the quality of our information systems, and by extension, our well being. (Cohen in Trends in Computer Virus Research) In the early 1990s, the network seemed to be a more open-minded society. Cohen was able to consider computer viruses in terms of the legitimacy of friendly contagion. The so-called benevolent virus appeared in his book A Short Course on Computer Viruses (Cohen 15). It was conceived of as a viral alternative to Turing logic. At the same time, physicist Mark Ludwig, driven by his desire to make technical information about computer viruses freely available, published the Black Book of Computer Viruses. Wired Magazine championed Ludwig’s ‘gruellingly meticulous analyses of viral performance and technique’ (Dibbell). In 1995, Tom Ray, a biologist turned computer programmer, created the viral-like Tierra program, an evolutionary race between digital hosts and parasites. Ray proposed that Tierra should exist in ‘a very large, complex and inter-connected region of cyberspace… inoculated with digital organisms, which will be allowed to evolve freely through natural selection’ (Ray)—ironically, something similar to what we are currently experiencing. In the early days, viral researchers were prompted to defend their work. In an interview in the virus webzine Alive in 1994, Cohen argued that a ‘symbol sequences without any known malicious side effects’ could not be considered as a bad idea. Ludwig contended that people were ‘brainwashed into believing that virus = bad…’ (Dibbell). However, more foreboding voices soon joined the debate. Spafford warned that while there is legitimate ‘scientific interest’ in viruses as a ‘means of modelling life’ and developing epidemiological defences, fellow researches should heed the dangers of further experimentation. True viruses are inherently unethical. For Spafford, the idea of a ‘good virus’ is an oxymoron. Following the exponential growth in malicious attacks in the mid-1990s, the idea of a good virus drifted considerably from the centre to the margins of the network society. In 1996, the IBM anti-virus researcher Sarah Gordon criticised Ludwig for elevating the status of the computer virus from the digital equivalent of a can of spray paint. With estimated costs to the worldwide Information Technolgy industry of $13 billion in 2001 (Pipkin 41) and the destructive force of a single worm costing tens of millions of dollars, not surprisingly the word ‘virus’ has developed a negative connotation. Even Cohen has realised that any acceptance of the benevolent virus would require considerable linguistic embellishment. Try ‘intelligent agents’, ‘artificial life’, ‘adaptive distributed networks’, and similar names and you will be far more successful. (Fed Cohen’s response to email questions posed by the author in June 2002) Within this heated climate, it was highly probable that Dr Aycock would stand accused of peddling a bad idea. Graham Cluley, a consultant for Sophos, rhetorically questions UoC’s ethics by asking, ‘should we teach kids how to break into cars if they’re interested in becoming a policeman one day?’ (Kelly). The anti-virus experts argue that by teaching how to ‘attack and destroy’ rather than ‘prevention, protection, and cure’, UoC will simply encourage the widespread contagion of the bad idea. However, UoC questions the naivety of this expert opinion. They argue that any ‘reasonably intelligent individual’ can access this information without attending university for four years. They claim it is ‘dangerous to think that virus writers can be stopped without a better understanding of how they operate.’ Maybe UoC are doing what academia does best. They are considering the virus in a new and unfamiliar light, clearing away ethical baggage, and crossing the moral boundaries of the network society. Deep-seated as it is, the analogy only goes so far. The network and the virus writer have developed their own biology, which is both technologically and culturally shaped. The search for a viral cure has to move away from the reactionary dissection of existing viral anatomies. Researchers need to look towards a pro-active engineering model that incorporates the complex human-computer assemblage. As one maverick expert suggests: Tomorrow’s experts need to learn to think beyond and develop better applications and operating systems that proactively block potential attack vectors rather than waiting to be attacked and then responding (a ‘security expert’ discussing the UoC programme in http://www.tla.ch/TLA/NEWS/2004sec/20040914Writting-Viruses.htm, 14 Sep. 2004) While many other types of furtive program, like ‘bots’, ‘crawlers’, and ‘spiders’ legitimately creep behind our screens, the virus is seen as a digital pariah. Whether or not the viral algorithm is benevolent or malevolent doesn’t seem to matter any more. The vast majority of the network society regards it as a bad idea. Nevertheless, Dr Aycock’s experiment with both the cultural and technological elements could produce a pro-active immunisation program. Whatever the conclusion, he should be applauded for attempting to carry out this experiment while beleaguered by so many experts who decide to judge innovation in terms of rigid moral outcomes.
