Abstract. Construction of warping dams destroys the consistency of annual maximum discharge series, which makes it difficult to calculate design floods, and even harder to calculate design floods in regions with no data. In this paper, an approach including consistency handling and regional formulae for statistical parameters was proposed to solve the problem encountered in calculation of design flood in no data regions influenced by warping dam projects. Analysis showed that the calculation results of such an approach are close to the actual situations and the approach has flexibility.

Any investment in the stock market will earn returns accompanied by risks. Return and risk has a mutual correlation that equilibrium. The formation of a portfolio is intended to provide a lower risk or with the same risk but provide a higher return. Value at Risk (VaR) is a instrument to analyze risk management. Time series model used in stock return data that it has not normal distribution and heteroscedastisicity is Generalized Autoregressive Conditional Heteroscedasticity (GARCH). GARCH-Copula is a combined method of GARCH and Copula. The Copula method is used in joint distribution modeling because it does not require the assumption of normality of the data and can capture tail dependence between each variable. This research uses return data from stock closing prices of Unilever Indonesia and Kimia Farma period January 1, 2013 until December 31, 2016. Copula model is selected based on the highest likelihood log value is Copula Clayton. Value at Risk estimates of Unilever Indonesia and Kimia Farma's stock portfolio on the same weight were performed using Monte Carlo simulation with backtesting of 30 days period data at 95% confidence level. Keywords : Stock, Risk, Generalized Autoregressive Conditional Heteroscedasticity (GARCH), Copula, Value at Risk

Latar Belakang : Salah satu masalah gizi pada balita adalah stunting. Beberapa penelitian sebelumnya telah menemukan kandungan gizi yang memiliki pengaruh pada pertumbuhan linear tubuh dalam kasus stunting seperti protein, seng, zat besi dan vitamin A. Tepung ikan haruan (HFF), tepung biji labu kuning(PSF) dan tepung buah labu kuning (PFF) adalah bahan lokal yang cukup mengandung gizi tersebut sehingga cocok digunakan sebagai bahan tambahan pada produk biskuit untuk balita.Tujuan : Penelitian ini bertujuan untuk mengetahui pengaruh formulasi biskuit (HPB) yang terdiri dari tepung terigu, HFF, PSF dan PFF terhadap kadar protein, seng, zat besi, vitamin A, dan daya terima biskuit untuk balita.Metode : Penelitian ini bersifat eksperimen menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali replikasi. HPB dibuat dengan proporsi tepung terigu: HFF: PSF: PFF masing-masing adalah P0 (100%:0%:0%:0%), P1 (50%:20%:20%:10%), P2 (50%:15%:15%:20%), P3(50%:10%:10%:30%). Analisis data pengaruh formulasi HPB terhadap kandungan gizi menggunakan one way anova, sedangkan untuk daya terima menggunakan analisis friedman pada warna, aroma, tekstur, dan rasa.Hasil : Uji statistik yang dilakukan menyatakan bahwa formulasi HPB tidak beda nyata (p>0,05) terhadap kadar protein dan vitamin A. Sebaliknya, formulasi HPB beda nyata (p<0,05) terhadap kadar seng, zat besi dan daya terima biskuit.Simpulan : Formulasi HPB memiliki pengaruh positif terhadap kadar seng dan zat besi biskuit. Kadar seng biskuit semakin meningkat pada formulasi dengan persentase HFF, PSF makin besar dan PFF makin kecil. Sebaliknya, kadar zat besi semakin meningkat, pada formulasi dengan persentase PFF makin besar dan HFF, PSF makin kecil.

The application of implant therapy is still limited, because of various risk factors and the long healing time required for bone-titanium integration. This study explores the potential for osseointegration engineering with dental pulp cells (DPCs) by testing a hypothesis that DPCs generate mineralized tissue on titanium. DPCs extracted from rat incisors positive for CD44, alkaline phosphatase activity, and mineralizing capability were cultured on polystyrene and on machined and dual-acid-etched (DAE) titanium. Tissue cultured on titanium with a Ca/P ratio of 1.4 exhibited plate-like morphology, while that on the polystyrene exhibited fibrous and punctate structures. Tissues cultured on titanium were harder than those on polystyrene, 1.5 times on the machined and 3 times on the DAE. Collagen I, osteopontin, and osteocalcin genes were up-regulated on titanium, especially the DAE surface. In conclusion, DPCs showing some characteristics of the previously identified dental pulp stem cells can generate mineralized tissue on titanium via the osteoblastic phenotype, which can be enhanced by titanium surface roughness.

This paper is to identify the implementation of hadith teaching and learning in secondary Islamic Education in Perak. This form of research uses quantitative methods. A total of 269 Islamic education teachers in daily secondary schools in Perak were selected as respondents using random sampling techniques. The study data were descriptively analyzed using Statistical Package for Social Sciences (SPSS) to obtain frequency, percentage, mean standard deviation. The findings on the time allocation construct were at moderately high levels (mean=3.51, s.p =0.3). Meanwhile, the findings of the teaching aid Material Construct mean score of the entire item are (mean=3.75, s.p=0.15) and the teachers’ interpretation is moderately high and the construct for teacher's teaching method “kitabah” the whole item's mean score is (mean=4.65, s.p=0.23) and interpretation at a high level. In conclusion, the main findings of the study show that teachers can implement good teaching methods to influence students' achievement. Despite the provision of teaching time and ease of teaching aids needs to be improved. The implications of the study show that the parties should increase their teaching time and expose the use of teaching materials to teachers so that students can master and improve sunnah practices in everyday life as derived from hadith learning in schools.

Geotextile tubes are used in dam construction because fine tailings are difficult to use. The shear characteristics of geotextile tubes during dam operation are closely related to those of the materials used to construct the tubes. Pull-out tests can accurately reflect the interfacial shear characteristics between geosynthetics in practice, so pull-out tests were carried out for different interfacial types of polypropylene woven fabrics under dry and wet states. The effects of the type of interface and dry-wet states on the interfacial shear characteristics were investigated, and the impact mechanisms were also discussed. The results indicated that P-type interfaces (the warp yarn on the interface is parallel to the pulling direction) tended to harden. However, PTP-type (the warp yarn on the interface is perpendicular to each other) and T-type (the weft yarn on the interface is parallel to the pulling direction) interfaces softened first and then tended to plateau after reaching peak shear stress, and softening became more obvious at higher normal stresses. The displacement corresponding to peak shear stress (referred to as “peak displacement” in this paper) of interfaces was positively correlated with the normal stress, and the wet state reduced the interfacial peak displacement. For different types of interfaces, the peak displacement of the T-type interface was the largest, followed by PTP-type and P-type. Interfacial shear characteristics conformed to Mohr–Coulomb strength theory and, compared with quasi-cohesion values ranging from 1.334 to 3.606 kPa, the quasi-friction angle significantly contributed to the interfacial shear strength. The quasi-friction angle of the interface was composed of a sliding friction angle and an occlusal friction angle. The shear strength of the interface was more sensitive to the interface types than whether they were in the dry or wet state. For different types of interfaces and dry-wet states, the change in the interfacial shear strength is respectively affected by the occlusal friction angle and the sliding friction angle on the interface.

Modern law enforcement agencies are constantly struggling with crimes against documents. Due to increasing quality of counterfeit documents and different physicochem­ical properties of inks, such crimes are becoming harder to detect. This situation obliges forensic laboratories for the development and implementation of testing procedures with the use of some modern techniques of chemical analysis. CE opens up numerous possibilities for various analytical applications, mainly due to its numerous advantages, the diversity of its modes and the compatibility with different detection systems. This study focuses on discussing two modes of CE: CZE and MECC and three different detection systems: DAD, LIF and MS. By using them information about substances exhibiting absorption, fluorescence and about molecular mass of analyzed compound can be received. In the Laboratory for Forensic Chemistry many different coloring matters were examined, including ballpoint, fountain pen, gel and stamp pad inks in most popular colors as well as a large group of branded and off-brand printing inks.The obtained results showed the great applicability of CE-DAD method. It has been proved that LIF and MS detections improve the discriminating possibilities of CE provid­ing additional information on samples.

Many high temperature applications require the measurement of analog voltages. This usually requires the integration of an ADC into the design. While the temperature degradation in performance of digital circuits is well known, the effects of temperature on analog circuitry are much harder to predict. Analog design is often an iterative process in which the characterization knowledge of a fabricated design is used to improve the next iteration of the design. This paper presents the results of the most recent iteration. This paper describes how the design of an existing 8-bit ADC was optimized for the SOI process. It also presents the characterization of the ADC at various temperatures up to 250°C and shows the effects of increased leakage on the ADC parameters of linearity, accuracy, and conversion speed. The ADC discussed is a successive approximation design which uses a resistive DAC. The design was modified to take advantage of the resistive characteristics inherent in the SOI process. Specifically, the DAC resistors were formed using N-type diffusion because of their superior matching as compared to using poly. The analog circuitry in the DAC switching and in the comparator required carefully choosing where to use “A” type versus “H” type transistor geometries to prevent inadvertent SCR failures. The ADC design also included a serial interface circuit that facilitates measurements within an oven by minimizing the number of connections required for operation. The measurements were taken using a 12-bit DAC to generate the analog input voltages to the 8-bit ADC under test. The ADC digital output was compared to the digital input to the DAC. All 4096 measurement points were taken at each voltage and temperature step. The results of these measurements were post-processed to extract the characterization data. There is a discussion of the results, the effects of leakage on those results, and how these effects might be overcome to produce more accurate ADC circuits in the future.

In recent years, there has been an increase in the number of teachers who lack motivation and self-efficacy in carrying out their duties. This factor causes a significant decline in school performance and productivity. Therefore, by knowing the level of teacher motivation and the level of self-efficacy of teachers, then the recommendations required by the government to produce quality and high-performing teachers will be known more clearly. Thus, the issue of producing quality and high-performing teachers are used to answer research questions and fill the research spaces found in this study. This study aims to identify the relationship between motivation and self-efficacy of teachers in High-Performance Secondary Schools, Cluster Schools of Excellence, and also Ordinary Day Schools in the state of Penang. A quantitative approach was used in the data collection process of this study. The study instrument consisted of three parts; namely demographics, teacher motivation, and self-efficacy of secondary school teachers. The study sample consisted of 122 secondary school teachers in three schools in the state of Penang. Quantitative data were analyzed using various tests, namely the Independent T-Sample test, one-way ANOVA, and Pearson correlation analysis using SPSS software. The findings of the study indicate that there are significant differences in teacher motivation based on teacher age category and teacher tenure. The findings of the study also showed that there were also significant differences in self-efficacy based on length of service. The correlation analysis test also showed that there was a significant relationship between teacher motivation and self-efficacy with a weak magnitude. Therefore, teacher motivation and teacher self-efficacy need attention as it is able to increase efficiency among teachers while improving the quality of the education system.

Nyamplung (Calophyllum inophyllum), a non-edible producing plant, is a tropical plant traditionally used by local residents as firewood, building material and medicinal plants. The research aimed to study the development of flower and fruit as well as oil content of nyamplung seeds. Two adult trees (P1 and P2) with different provenance were used in experiment. Morphology of flower and fruit, and seed germination were observed from the field, while the microscopic anatomical observations and oil content analysis were carried out in the laboratory. The result showed that a single generative bud generally had 8-15 flowers. The flower was arranged in bunches, with 4 petals, 4 sepals, single pistil and 4 files of anthers surrounded the pistil. In some cases, the flowers had 5 sepals, or 3 sepals and 3 anthers files. Fruits were round, green and turned to harden with brownish color during maturation. Flower bud grown from bud was ready to blossom 27 days after initiation (DAI). There were up to 48.52% flower buds drop at 24 DAI, and they were still increase up to 64.5% flower drop during the whole of flower development. The observation also showed that fruit drop rate of P2 plant was higher than P1. After flower bloom for 3 or 4 days after anthesis, the flowers started to lose their parts. The fruits started to ripe 8-10 week after anthesis (WAA). Seeds from P2 tree had oil content of 51.79%, which was higher than the P1 tree (42.57%).

Using in-depth interviews with twenty-six teen fathers, I explore how these young men negotiate the absent-father discourse in making sense of their identities as young dads. I find that teen fathers draw on culturally available notions of gender and age in their attempts to construct and maintain good-dad identities. Teen fathers deploy the expectation that “most dad’s aren’t around” to “lower the bar” and elevate their own performance by comparison. Teen fathers also feel the need to defend themselves from the discourse’s assumptions by invoking tropes of adult masculinity—insisting that “fatherhood means stepping up” and “being a man.” Because the fathers are unable to meet all the expectations of adult manhood, they create an escape hatch for themselves by citing their own adolescence and claiming a need for youthful freedom. Ironically, by invoking gendered and aged norms of adulthood, the fathers reify those norms into something harder to escape.

Acute Respiratory Distress Syndrome (ARDS) is a well-recognized clinical problem first described in the late sixties. However, its relevance seems to have increased since the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) outbreak, as 14% (CI 95% 2% to 59%) of patients admitted to the hospital present with this syndrome. Conceptually, a syndrome is a group of symptoms and signs that correspond to several diseases. Although defining disease is much harder than may appear at first glance, we can view it as the association between a syndrome and a pathology pattern. Diffuse alveolar damage (DAD) is the morphological hallmark of ARDS, although studies performed in autopsies and patients have demonstrated that it is present in only half of ARDS patients. The SARS-CoV-2 outbreak and the high incidence of ARDS associated with this infection have triggered a natural question: is the lung pathology similar in patients with ARDS associated with traditional risk factors than to SARS-CoV-2 infection? This review aims to analyze the lung pathology results of patients infected with the novel SARS Cov-2. As this article targets non-intensive care physicians, we will first describe the main characteristics of the novel SARS-Cov-2 and the ARDS definition, and then the lung pathology results from the UCI in this group of patients.

Background: Qianhu is a traditional Chinese medicine. It is thought that Qianhu roots will harden after bolting and not be suitable for medicinal purposes. Bolting Qianhu and unbolting Qianhu are referred to as “Xiong Qianhu” and “Ci Qianhu,” respectively. In this study, the properties, microscopic and chemical characteristics of Ci Qianhu and Xiong Qianhu roots were compared using fluorescence microscopy, laser microdissection coupled with ultra-high-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry, and high-performance liquid chromatography with diode-array detection. Results: Microscopy results showed that the area of secondary xylem in the root increased after bolting, with the cork and secretory canals showing strong fluorescence intensity. A total of 34 peaks, mostly pyranocoumarins, were identified in the tissues of Ci Qianhu and Xiong Qianhu. The secretory canals contained the highest variability of coumarins, whereas the secondary xylem contained the least coumarins. Moreover, seven coumarins, especially the pyran- coumarin, decreased after bolting. Generally, both before and after bolting, coumarin level was the highest in the bark, followed by the middle part, and the lowest in the inner part. Conclusion: Thus, it was indicated that the area of secondary xylem increased after bolting, however the coumarin variant and content decreased in the secondary xylem of Qianhu. The result shows that the quality of Qianhu decreases after bolting, which supports the viewpoint that Xiong Qianhu is not suitable for medicinal use.

Ethyl silicate is a colorless liquid with a slightly perceptible odor. This compound finds numerous applications in many industrial branches, e.g., paint and lacquer, chemical (in chemical coatings which has a contact with food), pharmaceutical, semiconductor and in nanotechnology. It is also used as an agent to harden natural stone, terra-cotta, artificial marble, frescoes and clay and in pro-duction of waterproof and acidproof mortar and cements. According to the State Sanitary Inspection data, in Poland in 2007, 2010 and 2013, there were no workers Ortokrzemian tetraetylu. Dokumentacja proponowanych dopuszczalnych wielkości narażenia zawodowego 23 exposed to ethyl silicate at levels exceeding maxi-mum allowable concentration (MAC) of 80 mg/m3. Ethyl silicate is well absorbed via respiratory and alimentary tracts, but its absorption through the skin is rather poor. In workers exposed to ethyl sil-icate, irritating properties to eye and nasal mucosa have been observed. Data on chronic ethyl silicate effects in humans are not available in the literature. In laboratory animals, ethyl silicate acute toxicity expressed in median lethal doses is relatively low. Ethyl silicate shows a mild irritating effect on rab-bit’s eyes, it does not cause dermal irritation or al-lergic effects. There are no data on ethyl silicate chronic toxicity. Short-term and subchronic studies performed on mice and rats exposed to ethyl sili-cate through inhalation and after its administration in other ways showed except for necrotic lesions in the olfactory epithelium of nasal cavity (in mice), changes in the liver (in rats) and kidneys. The latter comprised interstitial inflammation and necrotic lesions in renal tubules. Short-term exposure of rats to high ethyl silicate concentrations induced its toxic effect also on lungs. Ethyl silicate mutagenic effect has not been re-vealed in Ames tests. On the basis of few data, it has been proved that this compound did not cause reproductive and developmental toxicity. This compound has not been categorized by the Inter-national Agency for Research on Cancer (IARC) with respect to its potential carcinogenic risk. The presented evidence shows that the major toxic effect of ethyl silicate at high concentrations (over 2000 mg/m3) is eye and nasal mucosa irritation in humans, whereas the nephrotoxic effect and dam-age to the olfactory epithelium of nasal cavity are observed in laboratory animals. On the basis of the nephrotoxic effect of ethyl sili-cate, its maximum allowable concentration (MAC) was calculated. The results of two independent in-halation experiments in mice were used to deter-mine NOAEL value. Inhalation exposure of mice to ethyl silicate at concentration of 430 mg/m3 (50 ppm) for 90 days or 2 and 4 weeks did not cause nephrotoxic effects. This compound at higher con-centrations caused nephrotoxicity. Exposure to concentration of 760 mg/m3 (88 ppm) caused sig-nificant decrease in kidney weight, and after expo-sure to concentration of 865 mg/m3 (100 ppm) in 20% of animals interstitial inflammation of kidney tubules have been observed. The authors of the documentation proposed to adopt a concentration of 430 mg/m3 as NOAEC value of ethyl silicate for the nephrotoxic effects observed in mice. After adopting relevant uncertainty coefficients (total value, 8) the calculated MAC value for ethyl silicate is 54 mg/m3. Taking into consideration the fact that in 2008 SCOEL proposed a concentration of 44 mg/m3 as 8-h TWA for ethyl silicate, which was based on the same effects (nephrotoxicity) and NOAEC value adopted from the same experiments, it was pro-posed to assume a concentration of 44 mg/m3 as MAC value of ethyl silicate. This substance is in-cluded in the directive establishing the IV list of in-dicative occupational exposure limit values with-out establishing a short-term STEL value. The proposed MAC value for ethyl silicate should protect workers against systemic effect and poten-tial irritating effect. There are no reasons for adopt-ing STEL and BEI values for this compound.

Abstract The effects of size on the performance of three-cone bits were measured during laboratory drilling tests in shale at simulated downhole conditions. Four Reed HP-SM three-cone bits with diameters of 6, 7 7/8, 9, and 11 in. [165, 200, 241, and 279 mm] were used to drill Mancos shale with water-based mud. The tests were conducted at constant borehole pressure, two conditions of hydraulic horsepower per square inch of bit area, three conditions of rotary speed, and four conditions of weight-on-bit (WOB) per inch of bit diameter. The resulting rates of penetration (ROP's) and torques were measured. penetration (ROP's) and torques were measured. Statistical techniques were used to analyze the data. Introduction Drill bit manufacturers generally recommend WOB operating ranges for their bits in terms of pounds-force per inch of bit diameter. The practice of normalizing the per inch of bit diameter. The practice of normalizing the effect of bit size by expressing it in these terms has been widely used and often accepted as a "rule of thumb" in the drilling industry. Many have suspected that this rule of thumb may be an oversimplification because bit design tends to vary widely with size even in the same models, and hydraulic cleaning of the bit and bottom of the hole becomes much more difficult as size increases. A better understanding of the effects of size on bit performance and the validity of the WOB per inch of bit performance and the validity of the WOB per inch of bit diameter rule of thumb was sought by performing drilling tests with various-size bits under controlled laboratory conditions. Drilling tests were performed with four Reed HP-SM three-cone bits with diameters of 6, 7 7/8, 9, and 11 in. [165, 200, 241, and 279 mm]. As many variables as possible were held constant during the drilling tests, including rock type; confining pressure and overburden stress on the rock; mud type, properties, and temperature; and borehole pressure. Nozzle sizes and flow rates were selected so that each bit was tested at approximately the same conditions of hydraulic horsepower per square inch of bit area. Three rotary-speed conditions per square inch of bit area. Three rotary-speed conditions and four WOB per inch of diameter conditions were run. The resulting ROP's and torques were measured at each condition. A detailed statistical analysis was performed on me dam to determine the relationship between the independent variables of bit size, WOB, rotary speed, and hydraulic horsepower per square inch of bit area and the dependent variables of ROP, torque, and mechanical horsepower expended at the bit. Drill Bit, Rock, Mud, and Nozzle Selection Four new Reed HP-SM bits with diameters of 6, 7 7/8, 9, and 11 in. [165, 200, 241, and 279 mm] were provided by Reed Rock Bit Co. for the tests. The provided by Reed Rock Bit Co. for the tests. The HP-SM bit is specified in the IADC code under four classifications (537, 547, 617, and 627). The manufacturer recommends the HP-SM bit for both soft formations containing streaks of harder materials and medium-strength formations. The HP-SM bits have conical inserts except for the chisel-shaped inserts on the gauge row. The manufacturer's recommended operating ranges for WOB per inch of bit diameter and rotary speed are 3,000 to 6,000 lbf [525 to 1051 N/mm] per inch of bit diameter and 45 to 140 rev/min, respectively. Fig. 1 is a photograph of the HP-SM bits. The number of inserts, average insert diameter, and average insert length were measured and are listed in Table 1. The rock formation samples drilled were Mancos shale. Mancos shale is a Cretaceous, gray to black, shale/siltstone formation containing 10% clay composed of illite and chlorite. Samples 15 in. [394 mm] in diameter by 36 in. [914 mm] long were used for the 6–, 7 7/8–, and 9-in.- [165–, 200–, and 241-mm]-diameter bit tests. A sample 17 in. [445 mm] in diameter by 36 in. [914 mm] long was used for the 11-in.–[279-mm]-diameter bit test. All samples were originally cored from a massive surface outcropping located in central Utah and preserved for the drilling tests. Mancos shale has an unconfined compressive strength of 9,000 psi [62 053 kPa] and a permeability less than 1 d. Detailed rock properties permeability less than 1 d. Detailed rock properties and a comparison of laboratory and field shale drilling have been given previously. A "standard" water-based mud with properties listed in Table 2 was selected for the tests. To compare the performance of different-size bits, it was felt that hydraulic horsepower per square inch of bit area (HSI) should be held constant during the tests. It was also felt that similar pressure drops across the bit should be run if possible. Calculations were made to determine the nozzle diameters that would create approximately the same pressure drop at constant HSI conditions. SPEJ p. 473

Introduction: Bacteria of the genus Salmonella are important pathogens involved in the contamination of various foods, such as chickens, and may cause food poisoning. Aim: The present study aimed to review the literature on the prevalence of chickens contaminated with Salmonella spp., which are commercializated in different Brazilian states. Material and methods: This was a literary review. The absolute frequency and the total percentage of contaminated samples was calculated and the Qui-square statistical test was applied, considering statistically significant p <0.05. Results: 616 publications were retrieved, but only 10 articles were included to compose the results. The cataloged studies were carried out in 14 different brazilian states, and it was observed that of 5,030 chicken samples analyzed, the mean prevalence of samples contaminated with Salmonellawas 7,3% (n= 365). In addition, the prevalence of samples in the different studies ranged from 2.5% to 44.6%. The most prevalent serotype was S. Enteritidis (28,7%) and a statistically significant association between the type of raw material for commercialization and the result of the chicken samples microbiological analysis was observed (p<0.001), where the carcasses represented 90.1% of the contaminated samples. Conclusion: Thus, the data presented in this study can serve as subsidy for the development of necessary, political or legislative, measures that allow a better control of commercialized chickens in Brazil.Descriptors: Salmonella; Foodborne Diseases; Epidemiology.ReferencesSouza GC, Gonsalves HRO, Gonsalves HEO, Coêlho JLS.

Bioclimatology is applied for growing tea in the West of Nghe An province, where the tea is considered as a high economic efficient plant to be priorly cultivated for reducing poverty and getting rich. Based on the bioclimatic characteristics of tea plant and regional climatic data from 1980 to 2014, the bioclimatic diagrams are built and the tea cultivability is mapped in term of annual average temperature and total precipitation, for this region with regarding its district of Con Cuong as an analytical key. The climate, including both temperature and precipitation, in Con Cuong is relatively suitable for the tea plantation. The Western Nghe An, a land of approx. 1.4 million ha, could be classified in five areas with different suitability for tea plant. The unfavorable area occupies only 1% of total region and the four favorable rests account for 99% of total, in which, the most favorable area is largest with about 746,355 ha, i.e. over 50% of whole region. The three other areas are cultivable but they are less favorable in terms of either temperature or precipitation. Growing tea in Western Nghe An, even in favorable areas, it should be taken into account of the weather disadvantages in certain moments of the year such as extreme dry, cold, hot and rainy events.ReferencesAhmed S., 2014.

Sari. Zukini merupakan sayuran buah yang banyak diminati oleh konsumen. Sayuran ini memiliki kadar air yang tinggi. Petani memerlukan teknik budidaya yang tepat untuk meningkatkan kualitas buah zukini, diantaranya dengan penggunaan hormon giberelin (GA3) dan waktu panen yang tepat. Tujuan dari penelitian ini adalah untuk mengetahui efek penggunaan GA3 dan perbedaan waktu panen terhadap kualitas hasil buah zukini, yaitu nilai total padatan terlarut (TPT), kekerasan, dan kadar air buah. Penelitian menggunakan metode percobaan rancangan acak lengkap (RAL) factorial, dengan 2 faktor dan 5 ulangan. Faktor pertama yaitu konsentrasi GA3 (0 part per million (ppm) dan 300 ppm) dan faktor kedua yaitu waktu panen 5 hari setelah berbunga (HSB), 10 HSB, dan 15 HSB. Data diuji dengan analisis sidik ragam (ANOVA), dilanjutkan uji lanjut Duncan dengan taraf nyata 5% dan diolah menggunakan software SPSS 24. Hasil penelitian menunjukkan bahwa terdapat interaksi antara GA3 dan waktu panen terhadap kadar air buah zukini. Konsentrasi GA3 300 ppmmenghasilkan kulit buah yang lebih keras dibandingkan dengan GA3 0 ppm kemudian 10 HSB dan 15 HSB memiliki nilai kekerasan lebih keras dibandingkan 0 HSB. Nilai TPT untuk GA3 300 ppm dan GA3 0 ppm menghasilkan nilai yang sama, sedangkan 5 HSB dan 10 HSB menampilkan nilai TPT lebih tinggi ketimbang 15 HSB. Kata Kunci: Cucurbitaceae ∙ hormon ∙ kadar air ∙ kekerasan buah ∙ total padatan terlarut Abstract. Zucchini is a fruit vegetable that is a lot of demand by costumers. This vegetable has a high water content. The farmers needs proper cultivation techniques to improve the quality of zucchini, including the used of the hormone gibberelin (GA3) and the harvest periods. The aim this research was to know effect used GA3 and harvest periods toward zucchini fruit quality, that were total soluble solids (TDS), firmness and fruit water content. This study used a Completely Randomized Design (CRD) with factorial pattern with 2 factors and 5 replications. The first factors was concentration of GA3 (0 part per million (ppm) and 300 ppm) and the second factor was harvest periods (5 days after flowering (DAF), 10 DAF, and 15 DAF). Data were tested by analysis of variance (ANOVA), followed by Duncan Multiple Range test with a significance level of 5% and processed using SPSS 24 software. The results of the study showed that there were interactions between GA3 and harvest periods on moisture content of zucchini fruit. Concentration of GA3 300 ppm obtained fruit skin that is harder than GA3 0 ppm and 10 DAF, then 15 DAF have a harder firmness values than 0 DAF. TDS values for GA3 300 ppm and GA3 0 ppm presented the same value, then 5 DAF and 10 DAF showed TDS value higher than 15 DAF. Keywords: Cucurbitaceae ∙ fruit firmness ∙ hormone ∙ water content ∙ total soluble solids

Yuanmo [Sarcomyxa edulis (Y.C. Dai, Niemelä &amp; G.F. Qin) T. Saito, Tonouchi &amp; T. Harada] is an important edible and medicinal mushroom endemic to Northeastern China. Here we report the de novo sequencing and assembly of the S. edulis genome using single-molecule real-time sequencing technology. The whole genome was approximately 35.65 Mb, with a G + C content of 48.31%. Genome assembly generated 41 contigs with an N50 length of 1,772,559 bp. The genome comprised 9,364 annotated protein-coding genes, many of which encoded enzymes involved in the modification, biosynthesis, and degradation of glycoconjugates and carbohydrates or enzymes predicted to be involved in the biosynthesis of secondary metabolites such as terpene, type I polyketide, siderophore, and fatty acids, which are responsible for the pharmacodynamic activities of S. edulis. We also identified genes encoding 1,3-β-glucan synthase and endo-1,3(4)-β-glucanase, which are involved in polysaccharide and uridine diphosphate glucose biosynthesis. Phylogenetic and comparative analyses of Basidiomycota fungi based on a single-copy orthologous protein indicated that the Sarcomyxa genus is an independent group that evolved from the Pleurotaceae family. The annotated whole-genome sequence of S. edulis can serve as a reference for investigations of bioactive compounds with medicinal value and the development and commercial production of superior S. edulis varieties.

There are days when having a child with Down syndrome can mean losing all hope of being an ordinary mother: a mother with run of the mill concerns, a mother with run of the mill routines. I know. I’ve had such days. I’ve also found that sharing these feelings with other mothers, even those who have a child with a disability, isn’t always easy. Or straightforward. In part I believe my difficulty sharing my experience with other mothers is because the motherhood issues surrounding the birth of a child with Down syndrome are qualitatively different to those experienced by mothers who give birth to children with other disabilities. Disabilities such as autism or cerebral palsy. The mother who has a child with autism or cerebral palsy is usually viewed as a victim - as having had no choice – of life having dealt her a cruel blow. There are after all no prenatal tests that can currently pick up these defects. That she may not see herself as a victim or her child as a victim often goes unreported, instead in the eyes of the popular media to give birth to a child with a disability is seen as a personal tragedy – a story of suffering and endurance. In other words disability is to be avoided if at all possible and women are expected to take advantage of the advances in reproductive medicine – to choose a genetically correct pregnancy – thus improving their lives and the lives of their offspring. Within this context it is not surprising then that the mother of a child with Down syndrome is likely to be seen as having brought the suffering on herself – of having had choices – tests such as amniocentesis and CVS – but of having failed to take control, failed to prevent the suffering of her child. But how informative are tests such as pre-implantation diagnosis, CVS or amniocentesis? How meaningful? More importantly, how safe is it to assume lives are being improved? Could it be, for example, that some lives are now harder rather than easier? As one mother who has grappled with the issues surrounding prenatal testing and disability I would like to share with you our family’s experience and hopefully illuminate some of the more complex and troubling issues these technological advances have the capacity to create. Fraser’s Pregnancy I fell pregnant with Fraser in 1995 at the age of thirty-seven. I was already the mother of a fifteen-month old and just as I had during his pregnancy – I took the routine maternal serum alpha-fetoprotein blood screen for chromosomal abnormalities at sixteen weeks. It showed I was at high risk of having a child with Down syndrome. However as I’d had a similarly high-risk reading in my first pregnancy I wasn’t particularly worried. The risk with Fraser appeared slightly higher, but other than knowing we would have to find time to see the genetic counsellor again, I didn’t dwell on it. As it happened Christopher and I sat in the same office with the same counsellor and once again listened to the risks. A normal foetus, as you both know, has 46 chromosomes in each cell. But given your high AFP reading Fiona, there is a significant risk that instead of 46 there could be 47 chromosomes in each cell. Each cell could be carrying an extra copy of chromosome 21. And as you both know, she continued her voice deepening; Trisomy 21 is associated with mild to severe intellectual disability. It also increases the risk of childhood leukaemia; certain cardiac disorders and is associated with other genetic disorders such as Hirschsprung’s disease. We listened and just as we’d done the first time – decided to have a coffee in the hospital café. This time for some reason the tone was different, this time we could feel the high-octane spiel, feel the pressure pound through our bodies, pulsate through our veins – we should take the test, we should take the test, we should take the test. We were, were we not, intelligent, well-educated and responsible human beings? Surely we could understand the need to invade, the need to extract a sample of amniotic fluid? Surely there were no ifs and buts this time? Surely we realised we had been very lucky with our first pregnancy; surely we understood the need for certainty; for reliable and accurate information this time? We did and we didn’t. We knew for example, that even if we ruled out the possibility of Down syndrome there was no guarantee our baby would be normal. We’d done our research. We knew that of all the children born with an intellectual disability only twenty five percent have a parentally detectable chromosomal disorder such as Down syndrome. In other words, the majority of mothers who give birth to a child with an intellectual disability will have received perfectly normal, utterly reassuring amniocentesis results. They will have put themselves at risk and will have been rewarded with good results. They will have been expecting a baby they could cherish, a baby they could feel proud of – a baby they could love. Our Decision Should we relent this time? Should we accept the professional advice? We talked and we talked. We knew if we agreed to the amniocentesis it would only rule out Down syndrome – or a less common chromosomal disorder such as Trisomy 18 or Trisomy 13. But little else. Four thousand other known birth defects would still remain. Defects such as attention deficit disorder, cleft lip, cleft palate, clubfoot, congenital cardiac disorder, cystic fibrosis, epilepsy, ... would not magically disappear by agreeing to the test. Neither would the possibility of giving birth to a child with autism or cerebral palsy. Or a child with vision, hearing or speech impairment. Neurological problems, skin problems or behavioural difficulties... We were however strongly aware the drive to have a normal child was expected of us. That we were making our decision at a time when social and economic imperatives dictated that we should want the best. The best partner, the best career, the best house ... the best baby. I had already agreed to a blood test and an ultrasound, so why not an amniocentesis? Why stop now? Why not proceed with a test most women over the age of thirty-five consider essential? What was wrong with me? Put simply, the test didn’t engage me. It seemed too specific. Too focused. Plus there was also a far larger obstacle. I knew if I agreed to the test and the words chromosomal disorder were to appear – a certain set of assumptions, an as yet unspoken trajectory would swiftly emerge. And I wasn’t sure I would be able to follow its course. Beyond the Test I knew if the test results came back positive I would be expected to terminate immediately. To abort my affected foetus. The fact I could find it difficult to fall pregnant again after the termination or that any future foetus may also be affected by a birth defect would make little difference. Out the four thousand known birth defects it would be considered imperative not to proceed with this particular one. And following on from that logic it would be assumed that the how – the business of termination – would be of little importance to me given the perceived gravity of the situation. I would want to solve the problem by removing it. No matter what. Before the procedure (as it would be referred to) the staff would want to reassure me, would want to comfort me – and in soothing voices tell me that yes; yes of course this procedure is in your best interests. You and your baby shouldn’t be made to suffer, not now or ever. You’re doing the right thing, they would reassure me, you are. But what would be left as unsaid would be the unavoidable realities of termination. On the elected day, during what would be the twenty-second week of my pregnancy, I would have to consent to the induction of labour. Simultaneously, I would also be expected to consent to a foetal intra-cardiac injection of potassium chloride to ensure the delivery of a dead baby. I would be advised to give birth to a dead baby because it would be considered better if I didn’t hear the baby cry. Better if I didn’t see the tiny creature breathe. Or try to breathe. The staff would also prefer I consent, would prefer I minimised everyone else’s distress. Then after the event I would be left alone. Left alone to my own devices. Left alone with no baby. I would be promised a tiny set of foot and handprints as a memento of my once vibrant pregnancy. And expected to be grateful, to be thankful, for the successful elimination of a pending disaster. But while I knew the staff would mean well, would believe they were doing the right thing for me, I knew it wasn’t the road for me. That I just couldn’t do it. We spent considerably longer in the hospital café the second time. And even though we tried to keep things light, we were both subdued. Both tense. My risk of having a baby with Down syndrome had come back as 1:120. Yes it was slightly higher than my first pregnancy (1:150), but did it mean anything? Our conversation was full of bumps and long winding trails. My Sister’s Experience of Disability Perhaps the prospect of having a child with Down syndrome didn’t terrify me because my sister had a disability. Not that we ever really referred to it as such, it was only ever Alison’s epilepsy. And although it was uncontrollable for most of her childhood, my mother tried to make her life as normal as possible. She was allowed to ride a bike, climb trees and swim. But it wasn’t easy for my mother because even though she wanted my sister to live a normal life there were no support services. Only a somewhat pessimistic neurologist. No one made the link between my sister’s declining school performance and her epilepsy. That she would lose the thread of a conversation because of a brief petit mal, a brief moment when she wouldn’t know what was going on. Or that repeated grand mal seizures took away her capacity for abstract thought and made her more and more concrete in her thinking. But despite the lack of support my mother worked long and hard to bring up a daughter who could hold down a full time job and live independently. She refused to let her use her epilepsy as an excuse. So much so that even today I still find it difficult to say my sister had a disability. I didn’t grow up with the word and my sister herself rarely used it to describe herself. Not surprisingly she went into the field herself working at first as a residential worker in a special school for disabled children and later as a rehabilitation counsellor for the Royal Blind Society. Premature Babies I couldn’t understand why a baby with Down syndrome was something to be avoided at all costs while a baby who was born prematurely and likely to emerge from the labour-intensive incubator process with severe life-long disabilities was cherished, welcomed and saved no matter what the expense. Other than being normal to begin with – where was the difference? Perhaps it was the possibility the premature baby might emerge unscathed. That hope remained. That there was a real possibility the intense and expensive process of saving the baby might not cause any damage. Whereas with Down syndrome the damage was done. The damage was known. I don’t know. Perhaps even with Down syndrome I felt there could be hope. Hope that the child might only be mildly intellectually disabled. Might not experience any of the serious medical complications. And that new and innovative treatments would be discovered in their lifetime. I just couldn’t accept the conventional wisdom. Couldn’t accept the need to test. And after approaching the decision from this angle, that angle and every other angle we could think of we both felt there was little more to say. And returned to our genetic counsellor. The Pressure to Conform Welcome back, she smiled. I’d like to introduce you to Dr M. I nodded politely in the doctor’s direction while immediately trying to discern if Christopher felt as caught off guard as I did. You’ll be pleased to know Dr M can perform the test today, she informed us. Dr M nodded and reached out to shake my hand. It’s a bit of a squeeze, she told me, but I can fit you in at around four. And don’t worry; she reassured me, that’s what we’re here for. I was shocked the heavy artillery had been called in. The pressure to conform, the pressure to say yes had been dramatically heightened by the presence of a doctor in the room. I could also sense the two women wanted to talk to me alone. That they wanted to talk woman to woman, that they thought if they could get me on my own I would agree, I would understand. That it must be the male who was the stumbling block. The problem. But I could also tell they were unsure; Christopher was after all a doctor, a member of the medical profession, one of them. Surely, they reasoned, surely he must understand why I must take the test. I didn’t want to talk to them alone. In part, because I felt the decision was as much Christopher’s as it was mine. Perhaps a little more mine, but one I wanted to make together. And much to their dismay I declined both the talk and the amniocentesis. Well, if you change your mind we’re here the counsellor reassured me. I nodded and as I left I made a point of looking each woman in the eye while shaking her hand firmly. Thank you, but no thank you, I reassured them. I wanted the baby I’d felt kick. I wanted him or her no matter what. After that day the whole issue pretty much faded, in part because soon after I developed a heart problem, a tachycardia and was fairly restricted in what I could do. I worried about the baby but more because of the medication I had to take rather than any genetic issue to do with its well being. The Birth Despite my heart condition the birth went well. And I was able to labour naturally with little intervention. I knew however, that all was not right. My first glimmer of recognition happened as I was giving birth to Fraser. He didn't push against me, he didn't thrust apart the walls of my birth canal, didn’t cause me to feel as though I was about to splinter. He was soft and floppy. Yet while I can tell you I knew something was wrong, knew instinctively – at another level I didn't have a clue. So I waited. Waited for his Apgar score. Waited to hear what the standard assessment of newborn viability would reveal. How the individual scores for activity (muscle tone), pulse (heart rate), grimace (reflex response), appearance (colour) and respiration (breathing) would add up. I knew the purpose of the Apgar test was to determine quickly whether or not Fraser needed immediate medical care – with scores below 3 generally regarded as critically low, 4 to 6 fairly low, and over 7 generally normal. Fraser scored 8 immediately after birth and 9 five minutes later. His markers of viability were fine. However all was not fine and within minutes he received a tentative diagnosis – whispers and murmurs placing a virtual sticker on his forehead. Whispers and murmurs immediately setting him apart from the normal neonate. Whispers and murmurs of concern. He was not a baby they wanted anything to do with – an experience they wanted anything to do with. In a very matter of fact voice the midwife asked me if I had had an amniocentesis. I said no, and thankfully because I was still feeling the effects of the gas, the bluntness and insensitivity of her question didn't hit me. To tell the truth it didn't hit me until years later. At the time it registered as a negative and intrusive question – certainly not the sort you want to be answering moments after giving birth – in the midst of a time that should be about the celebration of a new life. And while I can remember how much I disliked the tenor of her voice, disliked the objectifying of my son, I too had already begun a process of defining, of recognising. I had already noted he was floppy and too red. But I guess the real moment of recognition came when he was handed to me and as a way of making conversation I suggested to Christopher our baby had downsy little eyes. At the time Christopher didn’t respond. And I remember feeling slightly miffed. But it wasn’t until years later that I realised his silence had been not because he hadn’t wanted to chat but because at that moment he’d let his dread, fear and sadness of what I was suggesting go straight over my head. Unconsciously though – even then – I knew my son had Down syndrome, but I couldn't take it in, couldn't feel my way there, I needed time. But time is rarely an option in hospital and the paediatrician (who we knew from the birth of our first son) was paged immediately. Disability and the Medical Paradigm From the perspective of the medical staff I was holding a neonate who was displaying some of the 50 signs and symptoms suggestive of Trisomy 21. Of Down syndrome. I too could see them as I remembered bits and pieces from my 1970s nursing text Whaley and Wong. Remembered a list that now seems so de-personalised, so harsh and objectifying. Flat faceSmall headFlat bridge of the noseSmaller than normal, low-set noseSmall mouth, causing the tongue to stick out and look unusually largeUpward slanting eyesExtra folds of skin at the inside corner of each eyeRounded cheeksSmall, misshapened earsSmall, wide handsA deep crease across the center of each palmA malformed fifth fingerA wide space between the big and second toesUnusual creases on the soles of the feetOverly-flexible joints (as in people who are double-jointed)Shorter than normal height Christopher and I awaited the arrival of the paediatrician without the benefits of privacy, only able to guess at what the other was thinking. We only had the briefest of moments alone when they transferred me to my room and Christopher was able to tell me that the staff thought our son had what I had blurted out. I remember being totally devastated and searching his face, trying to gauge how he felt. But there was no time for us to talk because as soon as he had uttered the words Down syndrome the paediatrician entered the room and it was immediately apparent he perceived our birth outcome a disaster. You’re both professionals he said, you both know what we are thinking. But he couldn’t bring himself to say the words, say Down syndrome, and instead went on about the need for chromosomal testing and the likelihood of a positive result. The gist, the message about our son was that while he would walk, might even talk, he would never cook, never understand danger and never live independently, never, never, never... Fraser was only an hour or so old and he’d already been judged, already been found wanting. Creating Fraser’s Cultural Identity The staff wanted me to accept his diagnosis and prognosis. I on the other hand wanted to de-medicalise the way in which his existence was being shaped. I didn’t want to know right then and there about the disability services to which I would be entitled, the possible medical complications I might face. And in a small attempt to create a different kind of space, a social space that could afford my son an identity that wasn’t focused on his genetic make-up, I requested it not be assumed by the staff that he had Down syndrome until the results of the blood tests were known – knowing full well they wouldn’t be available until after I’d left hospital. Over the next few days Fraser had to spend some time in the neonatal intensive care unit because of an unrelated medical problem. His initial redness turning out to be a symptom of polycythemia (too many red blood cells). And in many ways this helped me to become his mother – to concentrate on looking after him in the same way you would any sick baby. Yet while I was deeply confident I was also deeply ashamed. Deeply ashamed I had given birth to a baby with a flaw, a defect. And processing the emotions was made doubly difficult because I felt many people thought I should have had prenatal testing – that it was my choice to have Fraser and therefore my fault, my problem. Fortunately however these feelings of dejection were equally matched by a passionate belief he belonged in our family, and that if he could belong and be included in our lives then there was no reason why he couldn’t be included in the lives of others. How Prenatal Testing Shapes Our Lives It is now twelve years since I gave birth to Fraser yet even today talking about our lives can still mean having to talk about the test – having to explain why I didn’t agree to an amniocentesis. Usually this is fairly straightforward, and fairly painless, but not always. Women have and still do openly challenge my decision. Why didn’t I take control? Aren’t I a feminist? What sort of a message do I think I am sending to younger women? Initially, I wasn’t able to fathom how anyone could perceive the issue as being so simple – take test, no Down syndrome. And it wasn’t until I saw the film Gattaca in 1997 that I began to understand how it could seem such a straightforward issue. Gattaca explores a world in which genetic discrimination has been taken to its logical conclusion – a world in which babies are screened at birth and labeled as either valids or in-valids according to their DNA status. Valids have every opportunity open to them while in-valids can only do menial work. It is a culture in which pre-implantation screening and prenatal testing are considered givens. Essential. And to challenge such discrimination foolish – however in the film the main character Vincent does just that and despite his in-valid status and its inherent obstacles he achieves his dream of becoming an astronaut. The film is essentially a thriller – Vincent at all times at risk of his true DNA status being revealed. The fear and loathing of imperfection is palpable. For me the tone of the film was a revelation and for the first time I could see my decision through the eyes of others. Feel the shock and horror of what must appear an irrational and irresponsible decision. Understand how if I am not either religious or anti-abortion – my objection must seem all the more strange. The film made it clear to me that if you don’t question the genes as destiny paradigm, the disability as suffering paradigm then you probably won’t think to question the prenatal tests are routine and essential paradigm. That you will simply accept the conventional medical wisdom – that certain genetic configurations are not only avoidable, but best avoided. Paradoxically, this understanding has made mothering Fraser, including Fraser easier and more enjoyable. Because I understand the grounds on which he was to have been excluded and how out of tune I am with the conventional thinking surrounding pregnancy and disability – I am so much freer to mother and to feel proud of my son.

It also appeared in The Fitz Files (Sun-Herald 30 Mar. 2008) What Excites Me Today as a Mother I love that there is now hope. That there is not just hope of a new test, a reliable non-invasive prenatal test, but hope regarding novel treatments – of medications that may assist children with Down syndrome with speech and memory. And an increasingly vocal minority who want to talk about how including children in mainstream schools enhances their development, how children with Down syndrome can, can, can … like Persia and Tyler for example. That perhaps in the not too distant future there will be a change in the way Down syndrome is perceived – that if Fraser can, if our family can – then perhaps mothering a child with Down syndrome will be considered culturally acceptable. That the nexus between genetics and destiny will be weakened in the sense of needing to choose one foetus over another, but strengthened by using genetic understandings to enhance and assist the lives of all individuals no matter what their genetic make-up. And perhaps one day Down syndrome will be considered a condition with which you can conceive. Can imagine. Can live. And not an experience to be avoided at all costs.

Introduction The counterculture that arose during the 1960s and 1970s left lasting social and political reverberations in developed nations. This was a time of increasing affluence and liberalisation which opened up remarkable political opportunities for social change. Within this context, an array of new social movements were a vital ingredient of the ferment that saw existing norms challenged and the establishment of new rights for many oppressed groups. An expanding arena of concerns included the environmental damage caused by 200 years of industrial capitalism. This article examines one aspect of a current environment movement in Australia, the anti-Coal Seam Gas (CSG) movement, and the part played by participants. In particular, the focus is upon one action that emerged during the recent Bentley Blockade, which was a regional mobilisation against proposed unconventional gas mining (UGM) near Lismore, NSW. Over the course of the blockade, the conventional ritual of waving at passers-by was transformed into a mechanism for garnering broad community support. Arguably, this was a crucial factor in the eventual outcome. In this case, we contend that the wave, rather than a countercultural artefact being appropriated by the mainstream, represents an everyday behaviour that builds social solidarity, which is subverted to become an effective part of the repertoire of the movement. At a more general level, this article examines how counterculture and mainstream interact via the subversion of “ordinary” citizens and the role of certain cultural understandings for that purpose. We will begin by examining the nature of the counterculture and its relationship to social movements before discussing the character of the anti-CSG movement in general and the Bentley Blockade in particular, using the personal experience of one of the writers. We will then be able to explore our thesis in detail and make some concluding remarks. The Counterculture and Social Movements In this article, we follow Cox’s understanding of the counterculture as a kind of meta-movement within which specific social movements are situated. For Cox (105), the counterculture that flourished during the 1960s and 1970s was an overarching movement in which existing social relations—in particular the family—were rejected by a younger generation, who succeeded in effectively fusing previously separate political and cultural spheres of dissent into one. Cox (103-04) points out that the precondition for such a phenomenon is “free space”—conditions under which counter-hegemonic activity can occur—for example, being liberated from the constraints of working to subsist, something which the unprecedented prosperity of the post WWII years allowed. Hence, in the 1960s and 1970s, as the counterculture emerged, a wave of activism arose in the western world which later came to be referred to as new social movements. These included the civil rights movement, women’s liberation, pacifism and the anti-nuclear and environment movements. The new movements rejected established power and organisational structures and tended, some scholars argued, to cross class lines, basing their claims on non-material issues. Della Porta and Diani claim this wave of movements is characterised by: a critical ideology in relation to modernism and progress; decentralized and participatory organizational structures; defense of interpersonal solidarity against the great bureaucracies; and the reclamation of autonomous spaces, rather than material advantages. (9) This depiction clearly announces the countercultural nature of the new social movements. As Carter (91) avers, these movements attempted to bypass the state and instead mobilise civil society, employing a range of innovative tactics and strategies—the repertoire of action—which may involve breaking laws. It should be noted that over time, some of these movements did shift towards accommodation of existing power structures and became more reformist in nature, to the point of forming political parties in the case of the Greens. However, inasmuch as the counterculture represented a merging of distinctively non-mainstream ways of life with the practice of actively challenging social arrangements at a political level (Cox 18–19; Grossberg 15–18;), the tactic of mobilising civil society to join social movements demonstrates in fact a reverse direction: large numbers of people are transfigured in radical ways by their involvement in social movements. One important principle underlying much of the repertoire of action of these new movements was non-violence. Again, this signals countercultural norms of the period. As Sharp (583–86) wrote at the time, non-violence is crucial in that it denies the aggressor their rationale for violent repression. This principle is founded on the liberal notion, whose legacy goes back to Locke, that the legitimacy of the government rests upon the consent of the governed—that is, the people can withdraw their consent (Locke in Ball & Dagger 92). Ghandi also relied upon this idea when formulating his non-violent approach to conflict, satyagraha (Sharp 83–84). Thus an idea that upholds the modern state is adopted by the counterculture in order to undermine it (the state), again demonstrating an instance of counterflow from the mainstream. Non-violence does not mean non-resistance. In fact, it usually involves non-compliance with a government or other authority and when practised in large numbers, can be very effective, as Ghandi and those in the civil rights movement showed. The result will be either that the government enters into negotiation with the protestors, or they can engage in violence to suppress them, which generally alienates the wider population, leading to a loss of support (Finley & Soifer 104–105). Tarrow (88) makes the important point that the less threatening an action, the harder it is to repress. As a result, democratic states have generally modified their response towards the “strategic weapon of nonviolent protest and even moved towards accommodation and recognition of this tactic as legitimate” (Tarrow 172). Nevertheless, the potential for state violence remains, and the freedom to protest is proscribed by various laws. One of the key figures to emerge from the new social movements that formed an integral part of the counterculture was Bill Moyer, who, in conjunction with colleagues produced a seminal text for theorising and organising social movements (Moyer et al.). Many contemporary social movements have been significantly influenced by Moyer’s Movement Action Plan (MAP), which describes not only key theoretical concepts but is also a practical guide to movement building and achieving aims. Moyer’s model was utilised in training the Northern Rivers community in the anti-CSG movement in conjunction with the non-violent direct action (NVDA) model developed by the North-East Forest Alliance (NEFA) that resisted logging in the forests of north-eastern NSW during the late 1980s and 1990s (Ricketts 138–40). Indeed, the Northern Rivers region of NSW—dubbed the Rainbow Region—is celebrated, as a “‘meeting place’ of countercultures and for the articulation of social and environmental ideals that challenge mainstream practice” (Ward and van Vuuren 63). As Bible (6–7) outlines, the Northern Rivers’ place in countercultural history is cemented by the holding of the Aquarius Festival in Nimbin in 1973 and the consequent decision of many attendees to stay on and settle in the region. They formed new kinds of communities based on an alternative ethics that eschewed a consumerist, individualist agenda in favour of modes of existence that emphasised living in harmony with the environment. The Terania Creek campaign of the late 1970s made the region famous for its environmental activism, when the new settlers resisted the logging of Nightcap National Park using nonviolent methods (Bible 5). It was also instrumental in developing an array of ingenious actions that were used in subsequent campaigns such as the Franklin Dam blockade in Tasmania in the early 1980s (Kelly 116). Indeed, many of these earlier activists were key figures in the anti-CSG movement that has developed in the Rainbow Region over the last few years. The Anti-CSG Movement Despite opposition to other forms of UGM, such as tight sands and shale oil extraction techniques, the term anti-CSG is used here, as it still seems to attract wide recognition. Unconventional gas extraction usually involves a process called fracking, which is the injection at high pressure of water, sand and a number of highly toxic chemicals underground to release the gas that is trapped in rock formations. Among the risks attributed to fracking are contamination of aquifers, air pollution from fugitive emissions and exposure to radioactive particles with resultant threats to human and animal health, as well as an increased risk of earthquakes (Ellsworth; Hand 13; Sovacool 254–260). Additionally, the vast amount of water that is extracted in the fracking process is saline and may contain residues of the fracking chemicals, heavy metals and radioactive matter. This produced water must either be stored or treated (Howarth 273–73; Sovacool 255). Further, there is potential for accidents and incidents and there are many reports—particularly in the United States where the practice is well established—of adverse events such as compressors exploding, leaks and spills, and water from taps catching fire (Sovacool 255–257). Despite an abundance of anecdotal evidence, until recently authorities and academics believed there was not enough “rigorous evidence” to make a definitive judgment of harm to animal and human health as a result of fracking (Mitka 2135). For example, in Australia, the Queensland Government was unable to find a clear link between fracking and health complaints in the Tara gasfield (Thompson 56), even though it is known that there are fugitive emissions from these gasfields (Tait et al. 3099-103). It is within this context that grassroots opposition to UGM began in Australia. The largest and most sustained challenge has come from the Northern Rivers of New South Wales, where a company called Metgasco has been attempting to engage in UGM for a number of years. Stiff community opposition has developed over this time, with activists training, co-ordinating and organising using the principles of Moyer’s MAP and NEFA’s NVDA. Numerous community and affinity groups opposing UGM sprang up including the Lock the Gate Alliance (LTG), a grassroots organisation opposing coal and gas mining, which formed in 2010 (Lock the Gate Alliance online). The movement put up sustained resistance to Metgasco’s attempts to establish wells at Glenugie, near Grafton and Doubtful Creek, near Kyogle in 2012 and 2013, despite the use of a substantial police presence at both locations. In the event, neither site was used for production despite exploratory wells being sunk (ABC News; Dobney). Metgasco announced it would be withdrawing its operations following new Federal and State government regulations at the time of the Doubtful Creek blockade. However it returned to the fray with a formal announcement in February 2014 (Metgasco), that it would drill at Bentley, 12 kilometres west of Lismore. It was widely believed this would occur with a view to production on an industrial scale should initial exploration prove fruitful. The Bentley Blockade It was known well before the formal announcement that Metgasco planned to drill at Bentley and community actions such as flash mobs, media releases and planning meetings were part of the build-up to direct action at the site. One of the authors of this article was actively involved in the movement and participated in a variety of these actions. By the end of January 2014 it was decided to hold an ongoing vigil at the site, which was still entirely undeveloped. Participants, including one author, volunteered for four-hour shifts which began at 5 a.m. each day and before long, were lasting into the night. The purpose of a vigil is to bear witness, maintain a presence and express a point of view. It thus accords well with the principle of non-violence. Eventually the site mushroomed into a tent village with three gates being blockaded. The main gate, Gate A, sprouted a variety of poles, tripods and other installations together with colourful tents and shelters, peopled by protesters on a 24-hour basis. The vigils persisted on all three gates for the duration of the blockade. As the number of blockaders swelled, popular support grew, lending weight to the notion that countercultural ideas and practices were spreading throughout the community. In response, Metgasco called on the State Government to provide police to coincide with the arrival of equipment. It was rumoured that 200 police would be drafted to defend the site in late April. When alerts were sent out to the community warning of imminent police action, an estimated crowd of 2000 people attended in the early hours of the morning and the police called off their operation (Feliu). As the weeks wore on, training was stepped up, attendees were educated in non-violent resistance and protestors willing to act as police liaison persons were placed on a rotating roster. In May, the State Government was preparing to send up to 800 police and the Riot Squad to break the blockade (NSW Hansard in Buckingham). Local farmers (now a part of the movement) and activist leaders had gone to Sydney in an effort to find a political solution in order to avoid what threatened to be a clash that would involve police violence. A confluence of events, such as: the sudden resignation of the Premier; revelations via the Independent Commission against Corruption about nefarious dealings and undue influence of the coal industry upon the government; a radio interview with locals by a popular broadcaster in Sydney; and the reputed hesitation of the police themselves in engaging with a group of possibly 7,000 to 10,000 protestors, resulted in the Office for Coal Seam Gas suspending Metgasco’s drilling licence on 15 May (NSW Department of Resources & Energy). The grounds were that the company had not adequately fulfilled its obligations to consult with the community. At the date of writing, the suspension still holds. The Wave The repertoire of contention at the Bentley Blockade was expansive, comprising most of the standard actions and strategies developed in earlier environmental struggles. These included direct blocking tactics in addition to the use of more carnivalesque actions like music and theatre, as well as the use of various media to reach a broader public. Non-violence was at the core of all actions, but we would tentatively suggest that Bentley may have provided a novel addition to the repertoire, stemming originally from the vigil, which brought the first protestors to the site. At the beginning of the vigil, which was initially held near the entrance to the proposed drilling site atop a cutting, occupants of passing vehicles below would demonstrate their support by sounding their horns and/or waving to the vigil-keepers, who at first were few in number. There was a precedent for this behaviour in the campaign leading up to the blockade. Activist groups such as the Knitting Nannas against Gas had encouraged vehicles to show support by sounding their horns. So when the motorists tooted spontaneously at Bentley, we waved back. Occupants of other vehicles would show disapproval by means of rude gestures and/or yelling and we would wave to them as well. After some weeks, as a presence began to be established at the site, it became routine for vigil keepers to smile and wave at all passing vehicles. This often elicited a positive response. After the first mass call-out discussed above, a number of us migrated to another gate, where numbers were much sparser and there was a perceived need for a greater presence. At this point, the participating writer had begun to act as a police liaison person, but the practice of waving routinely was continued. Those protecting this gate usually included protestors ready to block access, the police liaison person, a legal observer, vigil-keepers and a passing parade of visitors. Because this location was directly on the road, it was possible to see the drivers of vehicles and make eye contact more easily. Certain vehicles became familiar, passing at regular times, on the way to work or school, for example. As time passed, most of those protecting the gate also joined the waving ritual to the point where it became like a game to try to prise a signal of acknowledgement from the passing motorists, or even to win over a disapprover. Police vehicles, some of which passed at set intervals, were included in this game. Mostly they waved cheerfully. There were some we never managed to win over, but waving and making direct eye contact with regular motorists over time created a sense of community and an acknowledgement of the work we were doing, as they increasingly responded in kind. Motorists could hardly feel threatened when they encountered smiling, waving protestors. By including the disapprovers, we acted inclusively and our determined good humour seemed to de-escalate demonstrated hostility. Locals who did not want drilling to go ahead but who were nevertheless unwilling to join a direct action were thus able to participate in the resistance in a way that may have felt safe for them. Some of them even stopped and visited the site, voicing their support. Standing on the side of the road and waving to passers-by may seem peripheral to the “real” action, even trivial. But we would argue it is a valuable adjunct to a blockade (which is situated near a road) when one of the strategies of the overall campaign is to win popular backing. Hence waving, whilst not a completely new part of the repertoire, constitutes what Tilly (41–45) would call innovation at the margins, something he asserts is necessary to maintain the effectiveness and vitality of contentious action. In this case, it is arguable that the sheer size of community support probably helped to concentrate the minds of the state government politicians in Sydney, particularly as they contemplated initiating a massive, taxpayer-funded police action against the people for the benefit of a commercial operation. Waving is a symbolic gesture indicating acknowledgement and goodwill. It fits well within a repertoire based on the principle of non-violence. Moreover, it is a conventional social norm and everyday behaviour that is so innocuous that it is difficult to see how it could be suppressed by police or other authorities. Therein lies its subversiveness. For in communicating our common humanity in a spirit of friendliness, we drew attention to the fact that we were without rancour and tacitly invited others to join us and to explore our concerns. In this way, the counterculture drew upon a mainstream custom to develop and extend upon a new form of dissent. This constitutes a reversal of the more usual phenomenon of countercultural artefacts—such as “hippie clothing”—being appropriated or co-opted by the prevailing culture (see Reading). But it also fits with the more general phenomenon that we have argued was occurring; that of enticing ordinary residents into joining together in countercultural activity, via the pathway of a social movement. Conclusion The anti-CSG movement in the Northern Rivers was developed and organised by countercultural participants of previous contentious challenges. It was highly effective in building popular support whilst at the same time forging a loose coalition of various activist groups. We have surveyed one practice—the wave—that evolved out of mainstream culture over the course of the Bentley Blockade and suggested it may come to be seen as part of the repertoire of actions that can be beneficially employed under suitable conditions. Waving to passers-by invites them to become part of the movement in a non-threatening and inclusive way. It thus envelops supporters and non-supporters alike, and its very innocuousness makes it difficult to suppress. We have argued that this instance can be referenced to a similar reverse movement at a broader level—that of co-opting liberal notions and involving the general populace in new practices and activities that undermine the status quo. The ability of the counterculture in general and environment movements in particular to innovate in the quest to challenge and change what it perceives as damaging or unethical practices demonstrates its ingenuity and spirit. This movement is testament to its dynamic nature. References ABC News.
