Abstract:

The rise of the Trump regime has sparked xenophobic sentiments directed toward and heightened fears experienced by mixed-status immigrant families living in the United States. Using the Southern Poverty Law Center’s concept of “The Trump Effect”—how the election of Donald Trump has had a damaging impact on undocumented immigrants—the researchers reveal how the lives of 12 mixed-status families (16 youth and 16 of their parents/guardians) have been transformed. Implications of this investigation are significant given the current social and political landscapes and continual fear mixed-status families undergo in their plight for daily survival.

Abstract:

SummaryThis paper briefly reviews how the ICD-11 and DSM-5 are going to handle the various continua existing in the area of mood disorders. The two systems will address the continua between “normal” elation and hypomania, between unipolar depression and bipolar disorder, and between anxiety disorders and depression in a more consistent way than in the past, while there will be differences in the characterization of mixed states and schizoaffective disorders. A major weakness of both systems will be the fact that the boundary between “normal” sadness and depression will not be based on a solid empirical evidence.

Abstract:

<p>Within experimental range on arena of the river Dnepr in natural reserve "Dneprovsko-Orelsky" in 241 points electric conductivity of soil has been measured by two ways: in a condition of natural humidity and in a condition of a full moisture capacity. It is established that on the average electrical conductivity makes 0.068±0.002 and 0.267±0.014 dSm/m accordingly. As a result of the carried out research by us the established procedure which allows to transform point objects which contain the information on electric conductivity of soil in continual (raster) layer on the basis of established regression dependences of an investigated indicator from predictors which are received on the basis of data of remote sensing of a surface of the Earth. Canonical axes received as a result of the mixed correspondence analysis have been used as regression predictors. Continual data (digital elevation model and its derivative, vegetative and other Landsat indexes, relief and vegetative cover diversity indexes) and discrete data (results of Earth surface classification on elementary relief units and types of a vegetative cover) have been calculated by mixed correspondence analysis. The important result is dependence of electric conductivity of soil on indicators of a relief and a vegetative cover diversity.</p>

Abstract:

In 1997, long-term thinning experiment Všeteč in Southern Bohemia was established in the young 19-year-old mixed beech and spruce stand. Three variants (0.10 ha each) were investigated: 1 – control unthinned plot (only salvage cut was done), 2 – plot with positive selection from above and 3 – plot with negative selection from below. The aim of this paper is to evaluate the first results from the eleven-year investigation (at the age of 19–29 years) focused on the effect of thinning on growth, species composition, litter-fall and humus in young mixed stands in this experiment. Thinning (both variants) resulted in decreased salvage cut (dead, broken and uprooted trees). Continual diminishing of spruce portion (started quickly after dry season in 2003 on control unthinned plot) was slow or soft on both thinned plots. Annual litter-fall in experimental young spruce and beech mixed stands at the age of 27–29 years varied from 4.6 to 5.5 thousand kg/ha and dry biomass of humus horizons L, F and H represented altogether approximately 91 and 128 thousand kg/ha on plots 3 and 1, respectively (plot 2 was omitted from this part of investigation).

Abstract:

In this article, the Tabular CUSUM (Cumulative Sum) Charts statistic method is employed to analyze the strength quality control of ready-mixed concrete for rigid pavement, for which the CUSUM is also used to analyze and monitor the micro changes of process mean for the strength of the ready-mixed concrete. The result of analytical study supports that the CUSUM statistical analysis skill is more sensitive than the Shewhart Control Chart in terms of designed mixing ratio parameter, water-cement ratio, and admixtures analyzed under the same concrete strength. When micro changes are presented in continuous mean strength value of the ready-mixed concrete, it can detect the continual changes of the concrete quality in a more accurate way. By combining the CUSUM statistical analysis and Shewhart Control Chart, higher accuracy of the quality control analysis could even be achieved in order the enhance quality control performance when pouring the ready-mix concrete on rigid pavement.

Abstract:

Based upon the extended framework of Hamilton’s principle, unified space–time finite element methods for viscoelastic and viscoplastic continuum dynamics are presented, respectively. For numerical efficiency, mixed time-step algorithm in time- and displacement-based algorithm in space are adopted. Through analytical investigation, we demonstrate that the Newmark’s constant average acceleration method and the present method are the same for viscoelasticity. With spatial eight-node brick elements, some numerical simulations are undertaken to validate and investigate the performance of the present non-iterative space–time finite element method for viscoplasticity.

Abstract:

The startup of a wet retention pond designed for extended stormwater treatment was monitored by more than one year of continual measurement of hydraulic parameters, nutrients and quality parameters in the pond itself (pH, temperature, dissolved oxygen, turbidity). The data revealed that photosynthesis played an important role for dissolved oxygen and pH for most of the year. Another important observation was that the pond behaved more like a completely mixed reactor than like a plug flow reactor—even though the length to width ratio was as high as 4.5:1. The pond was equipped with sand filters and sorption filters whereby very good nutrient removal efficiencies were achieved.

Abstract:

The issue of linguistic distinctions in creole continua has been extensively debated. Are creole continua comprised of just an “acrolect” and a “basilect,” or do they also comprise additional varieties? Studies of variation in creole continua have been typically based on directly observed linguistic data. This study argues that perceived sociolinguistic distinctions can offer one point of departure for establishing what linguistic components constitute creole continua. Following a protocol developed within “Perceptual Dialectology” (see, e.g., Preston 1999) this study describes perceived sociolinguistic distinctions via folk linguistic descriptors elicited by means of linguistic map-drawing and labeling tasks. The aim of this study is to investigate perceived language variation in the Caribbean island of Trinidad, where Standard English historically co-exists as an official language with creolized varieties of English, which the literature generally refers to as “Trinidadian Creole English.” The main finding of this study is that Standard English has a strong perceptual association with Trinidad’s historic urban centers, while non-standard varieties collectively referred to as “dialect” or “creole” are associated with the rest of the island. The study discusses indications that linguistic boundaries—largely parallel to ethnoracial boundaries—are perceived within the standard and non-standard part of the Trinidadian continuum. One major perceived linguistic criterion for differentiation within the non-standard part of the continuum is the presence or absence of Standard English elements. The saliency of “mixed” varieties suggests that a variety located halfway between Standard English and Trinidadian Creole English could be emerging. The study concludes that the urban-rural divide and ethnoracial distinctions constitute two salient social fault lines that future studies of language variation in Trinidad should take account of while searching the Trinidadian continuum for objectively verifiable linguistic boundaries.

Abstract:

Though gas quenching has several advantages, such as minimal environmental impact, little deformation, low energy cost, clean products, and ability to control the cooling locally and temporally for best product properties, its cooling performance is less than that of oil and water. If gas is mixed with spray water, the mixture will has favorable cooling performance. The cooling performance of eject quenching by mixture of Nitrogen-spray water is studied experimentally. Alloy steel 9SiCr is specimen, and it is quenched by a certain proportion of mixture gas of Nitrogen and spray water under normal pressure and high velocity, and the continual cooling curve is determined. The experimental results show that it can improve the cooling effect of quenching medium on the one hand; on the other hand, it can decrease the deformation and residual stress of specimen. The results also show that cooling performance of the mixture and cooling velocity can be enhanced by increasing gas pressure when the mixture ratio is fixed, and it takes short time to cool to room temperature. The cooling performance of the mixture and cooling velocity can be enhanced by increasing the mixture ratio under same pressure, and it also takes short time to cool to the room temperature. The continual cooling curve is determined, which gives the information of cooling performance of eject quenching by mixture of Nitrogen-spray water under Normal pressure changed with the pressure and the mixture ratio of Nitrogen and spray water.

Abstract:

Undoubtedly, managing student discipline is one of the concerns of higher education institutions in the Philippines nowadays. However, despite the so many strategies to alleviate serious and not so serious offenses in EAC-Cavite, there have never been any established guidelines to evaluate student discipline occurrences and intervention as the basis for continual improvement. This study evaluates the major types of student discipline and analyzes its kind of offense incurred by students for Academic Year 2018-2019 from the 14 schools in EAC-Cavite which are categorically divided into five (5) clusters. This study uses the mixed methods of research using the data gathered daily by the Discipline Officers. The data were summarized using frequency and percentage or according to the number of offenses recorded each month and the recorded incidents per cluster. The Focus Group Discussion (FGD) was also conducted among 20 student offenders who voluntarily provide reasons of such occurrences. The students analyzed and gave their possible solutions to improve their habits. Although this study is a nonexperimental, this implies that this evaluation documents the college-wide intervention and the role of the Office of Student Affairs (OSA) to improve their reporting technique on student discipline. Findings show that there were fewer occurrences per cluster after the intervention; however, for continual improvement purposes, this study recommends a continuous evaluation of the OSA’s disciplinary procedures, intervention guidelines, and reporting strategies to enhance student services at EAC-Cavite.

Abstract:

Compared with the monistic structure of crop agriculture in Southwest Asia and Mesoamerica, agriculture in ancient China reflects the characteristics of a dualistic structure with millet in the north and rice in the south. It is argued that the rice and millet farming modes were mutually exchanged during their development and formed a vast region of mixed farming. However, the time and place of its origin, the routes of dissemination, and the development patterns and possible influence factors of mixed farming remain unclear. This study systematically collected information from 804 sites with millet and rice records and detailed floatation results from 78 mixed farming sites in prehistoric China. Three north–south communication corridors are identified between the upper, middle and lower Yellow and Yangtze River Valleys that began around 5500 BP, 8400 BP and 4600 BP, respectively. Cultural communication accompanied by human migration and the unique natural environment of loess and East Asia monsoons facilitated the interaction between millet and rice farming through these corridors. As a comprehensive reflection of the interaction between millet and rice farming, the crop structure of the four core mixed farming regions is in a continual process of adjustment, with the selection of foxtail millet in the southward spread of millet agriculture and temperate Oryza japonica in the northern spread of rice agriculture.

Full text

Abstract:

Plants adapt to continual changes in environmental conditions throughout their life spans. High-throughput phenotyping methods have been developed to noninvasively monitor the physiological responses to abiotic/biotic stresses on a scale spanning a long time, covering most of the vegetative and reproductive stages. However, some of the physiological events comprise almost immediate and very fast responses towards the changing environment which might be overlooked in long-term observations. Additionally, there are certain technical difficulties and restrictions in analyzing phenotyping data, especially when dealing with repeated measurements. In this study, a method for comparing means at different time points using generalized linear mixed models combined with classical time series models is presented. As an example, we use multiple chlorophyll time series measurements from different genotypes. The use of additional time series models as random effects is essential as the residuals of the initial mixed model may contain autocorrelations that bias the result. The nature of mixed models offers a viable solution as these can incorporate time series models for residuals as random effects. The results from analyzing chlorophyll content time series show that the autocorrelation is successfully eliminated from the residuals and incorporated into the final model. This allows the use of statistical inference.

Abstract:

The buoyancy range, which represents a transition from large-scale wave-dominated motions to small-scale turbulence in the oceans and the atmosphere, is investigated through large-eddy simulations. The model presented here uses a continual forcing based on large-scale standing internal waves and has a spectral truncation in the isotropic inertial range. Evidence is presented for a break in the energy spectra from the anisotropic k−3 buoyancy range to the small-scale k−5/3 isotropic inertial range. Density structures that form during wave breaking and periods of high strain rate are analysed. Elongated vertical structures produced during periods of strong straining motion are found to collapse in the subsequent vertically compressional phase of the strain resulting in a zone or patch of mixed fluid.

Abstract:

Flexibility in course scheduling is an integral part of institutional strategies used to increase student engagement and success, yet little research exists that examines scheduling as a key factor that determines students’ experiences and educational outcomes. This study explored the undergraduate sport science students and their teachers at Jimma University, Ethiopia, regarding their experiences in semester-based and block scheduling formats as well as their reflections and perspectives on the effectiveness of these scheduling formats for teaching and learning. For this, the study used an exploratory mixed-methods design consisting of individual interviews with six teachers and focus group interviews with undergraduate sports sciences student sample (n = 40), and institutional archives of the sampled students’ cumulative grade point averages (GPAs). The study findings indicate divergent views regarding their perceptions and mixed experiences with the semester-based and block scheduled courses. Irrespective of these, the majority of participants reported that teachers’ missing scheduled classes, tending not to teach the full time of the class session, continual lecturing, and scarcity of instructional resources are the major challenges surrounding the implementation of both semester-based and block teaching. We discuss the implications of these findings for future research, implementation, and intervention design.

Full text

Abstract:

Abstract The paper presents a rigorous and straightforward approach for obtaining the 2D boundary integral equations for a thermoelastic half-space containing holes, cracks and thin foreign inclusions. It starts from the Cauchy integral formula and the extended Stroh formalism which allows writing the general solution of thermoelastic problems in terms of certain analytic functions. In addition, with the help of it, it is possible to convert the volume integrals included in the equation into contour integrals, which, in turn, will allow the use of the method of boundary elements. For modelling of solids with thin inhomogeneities, a coupling principle for continua of different dimensions is used. Applying the theory of complex variable functions, in particular, Cauchy integral formula and Sokhotski–Plemelj formula, the Somigliana type boundary integral equations are constructed for thermoelastic anisotropic half-space. The obtained integral equations are introduced into the modified boundary element method. A numerical analysis of the influence of boundary conditions on the half-space boundary and relative rigidity of the thin inhomogeneity on the intensity of stresses at the inclusions is carried out.

Abstract:

AbstractWind-forced internal waves close to the inertial frequency are ubiquitous throughout the world’s oceans, but observational constraints on their global energetics and impact on subsurface mixing remain scarce. This study reports on velocity measurements from three Electromagnetic Autonomous Profiling Explorers (EM-APEX) deployed in February 2009. These floats observed downward-propagating near-inertial internal waves near the Subantarctic and Polar Fronts of the Antarctic Circumpolar Current. These waves were episodic and enhanced at middepth between 500 and 1000 m. Depth-integrated kinetic energy varied between 1 and 7 kJ m−2 and averaged 1.6 kJ m−2 with typical group velocities of 40 m day−1, implying an average energy flux of 3 mW m−2 at the mixed layer base decreasing to approximately 25% of that value at 1500 m. Modeled currents forced by reanalysis winds along each float track agree with observed surface currents from EM-APEX, provided that mixed layer depth is restricted to the layer of weakest observable stratification (interpreted as the maximum depth that can remain mixed over an inertial period given the continual balance between mixing and restratification). This model estimates an average wind power of 3 mW m−2. Shipboard wind and current observations during a strong storm show an integrated wind work of 3.5 kJ m−2, comparable to the vertically integrated kinetic energy over the following month. Model wind work estimates are considerably less, likely because of the mixed layer depth used. A model with varying stratification in response to the wind provides a better match to the observations, emphasizing the importance of stratification within the mixed layer in amplifying wind energy input.

This research develops our understanding of classical music audiences, and highlights the continued individualistic, middle-class, and exclusionary culture of classical music attendance and patterns of behaviours. The research also suggests that a mobile phone app does prove a useful mechanism for selling discounted tickets, but shows little indication of being a useful means of expanding this audience beyond its traditional demographic.

Abstract:

Transient liquid phase bonding of Al/Mg2Si metal matrix composite (MMC) was investigated using a Cu-Ni mixed powder interlayer (1:1 proportion by weight) in an argon environment at various temperatures and holding time. The composite (MMC), containing 15% Mg2Si particles, was produced by in situ technique. The use of pure copper interlayer in Al/Mg2Si metal matrix composite causes reinforcement particles segregation at the bond interface. The region of weakness produced by the particles segregation at the bond region has been found to promote preferential failure during tensile testing. Using a mixture of Ni and Cu powder as filler material have shown less segregation of particles reinforcement along central bond zone. The composition and microstructure of the joined area were examined by X-ray diffraction (XRD) and scanning electron microscopy equipped with an energy dispersive X-ray spectroscopy (EDS). Shear tests were conducted to the samples to evaluate the effect of bonding duration on weldabillity. As the bonding time increases, with continual diffusion, the structural heterogeneity is diminished, and the microporosities are eliminated at the central bond zone. The shear strength of joints increased with increasing bonding duration.

Abstract:

In the overly constrained space of the federal audit environment, to what extent can critical thinking skills be applied in a profession characterized by arduous public trust expectations, controlling auditing standards, prescriptive federal acquisition policies, frequently changing guidance, continual peer oversight, and the slow implementation of audit findings? Promoting the increased use of private sector auditors may suggest that federal auditors perceive competencies differently. However, a recent survey administered to 645 auditors of a federal audit agency region indicated that the majority of the core competencies identified by the American Institute of Certified Public Accountants are perceived as relevant in auditing government contractors. However, of concern, the data were mixed in support of critical thinking as an important competency. Given employer preference for skills in this area, the author attempts to identify applications to increase auditor critical thinking skills and to offer suggestions for increasing the relevance of the federal audit.

Abstract:

Civil aviation is a high-risk industry where actors are experiencing increasing focus on economic performance, greater international competition, and growing safety threats that require continual organizational adjustments. In this article, we present the findings of a case study conducted within the Norwegian national air traffic management organization—Avinor, in preparation for a major reorganization initiative. In this study, we mapped the aggregated readiness and positioning for organizational change in the three main air traffic control centers in Norway using a mixed-method approach to person–environment Fit to help organizational leaders better understand each unit’s positioning for change, and more specifically, individual preferences for change styles. The results suggest that participants at the different air traffic control centers had developed distinctly different change preferences at both the group and individual levels, and that each was distinctly different from the other units in their positioning and readiness for change.

Abstract:

PurposeEffective Emergency Response Management (ERM) system evaluation is vital to the process of continual improvement within emergency response organizations. The purpose of this paper is to investigate if an entire ERM system can be captured and encoded within a standardized framework.Design/methodology/approachEmploying an exploratory approach the authors apply a mixed methods case study design and inductive reasoning to analyse documentary evidence provided during the inquest into the London Bombings 2005. The authors use content analysis to investigate the nature of ERM system data availability and apply principals of Network Theory to iteratively develop a framework within which data can be encoded.FindingsThe authors find that complex ERM system data can be captured and stored within a standardized framework. The authors present a conceptual framework and multi-stage mixed methods process, the Standardized Emergency Response Incident Evaluation System (SERIES) model, to support data collection, storage and interpretation. The findings demonstrate that ERM system evaluation can benefit from the adoption of a standardized mixed-methods approach employing data transformation and triangulation. The authors also demonstrate the potential of the proposed standardized model, by integrating qualitative and quantitative data, to support interpretation and reporting through the use of appropriate data visualization.Originality/valueThe SERIES model provides a practical tool and procedural guidelines to capture and share vital ERM system data and information across all emergency services. It also presents an opportunity to develop a large comprehensive multi-incident dataset to support academic inquiry and partnership between academics and practitioners.

Abstract:

SUMMARYUnisexual females, (80–100 days post-infection) were cultured in vitro and exposed to mature male worms from either mixed or single-sex infections. A comparison was made of the uptake of [3H]thymidine (used as a marker for DNA synthesis) by isolated unisexual females or by those females exposed to males derived from either mixed or unisexual infections during in vitro culture. All males were observed to be paired with females by approximately 18 h post-culture. At 24 h post-culture females paired with males from mixed infections had an elevated uptake of [3H]thymidine compared to females that had not paired and uptake was also significantly different (P ≥ 0–001) from females exposed to males from unisexual infections. By 48 h there was no significant difference between uptake in females paired with either type of male. The frequency of uptake in the paired females was approximately double that in unstimulated females while non-paired females in the presence of males had an increase of between 35 nd 45%. In a second experiment the effect of depriving a mature egg-laying female of the paired male was investigated. These females had a continual decrease in uptake of [3H]thymidine compared to mature females maintained with male partners. The uptake of [3H]thymidine was used as a marker for DNA synthesis and the effect of the male worm on DNA synthesis in the unisexual female is discussed in view of the above results.

Abstract:

In this paper, the modeling, analysis and monitoring of a room-and-pillar mining technology in an Estonian underground mines is presented. Technology is based on continuous miner as the primary production machine. Many technical and economic parameters o f production, including loss of useful minerals, depend on a correct choice of the sizes for these elements. Without the account o f reological properties o f covered rocks, in particular the character of change o f their long strength, the account of the sizes of rooms and pillars on a certain determined term is impossible. For the modeling, the existing room- and-pillars determination method by IMS and with formulas by V. Undusk, Visual Basic for Application in Excel, Maplnfo, and Fast Lagrangian Analysis of Continua was used. Model allows determining the parameters of spontaneous collapse of the pillars and\ surface subsidence, optimized the working parameters for continuous mining. Proposed method suits for stability analysis, failure prognosis and monitoring.

Abstract:

A continue method based on relaxation is applied to solve the unit commitment problem (UCP). At first, the primal UCP is reformulated as a simple mixed integer quadratic programming (MIQP), and then the MIQP is solved by interior point method (IPM) and commercial software CPLEX. The first continues problem, UCP without integer constraints, can be solved by IPM to get the no integer solution. The second continues problem, an equivalent continues problem of UCP, can be solved starting from the solution obtained in first problem.

Abstract:

The villages of rural Alaska comprise one of the most exceptional, yet least visible, sociocultural environments in the United States They are geographically remote, and set off from the mainstream also by their unique Eskimo, Indian or Aleut cultures. At the same time many economic, legal and cultural connections pull these villages toward the dominant U.S. society, impelling continual and rapid social change. Our research focuses on adolescents growing up in this culturally complex and changing environment. We employ survey data from adolescents in 19 rural schools to explore relationships between ethnic identity and students' expectations about moving away or attending college. Many students describe their ethnic identity as mixed, both Native and non-Native. On some key variables, the responses of mixed-identity students fall between those of Natives and non-Natives, supporting a theoretical conception of ethnicity as a matter of degree rather than category. Migration and college expectations vary with ethnic identity, but the college expectations/identity relationship fades when we adjust for other variables. Ethnicity affects expectations for the most part indirectly, through “cultural tool kit” variables including family role models and support. Gender differences in expectations, on the other hand, remain substantial even after adjusting for other variables.

Abstract:

Flipped classroom models allocate more time for active learning approaches compared with more traditional pedagogies, however what is less clear with the utilisation of flipped learning is evidence to support whether students in flipped classes are given more opportunities to develop higher order thinking skills (HOTs) to effect deep learning compared with the traditional ways of teaching. Focussing on this gap, this study compares on campus and off campus student engagement in two courses using different deliveries: online face-to-face (f2f) mixed mode (on campus students attend traditional f2f on campus classes and off campus students study exclusively online) versus fully online mode, utilising flipped classes (all student study off campus engaging in flipped virtual classes). Final course grades were similar for both deliveries; however, the study suggests flipped classes offered students more opportunities to develop HOTs and engage more deeply in the learning process. Students’ evaluations of the online flipped delivery were mixed, with those students previously enrolled exclusively as on campus, particularly dissatisfied with fully online delivery and virtual class tutor experience. Recommendations are made concerning both the timing of the introduction of fully online delivery in a program and the need for continual up-skilling of staff who teach in online environments.

Abstract:

AbstractFirm operators continually manage multiple sources of risk. In an application to cattle feedlot operations, our objective is to determine if producers view output price and animal health risks separately or jointly. We conduct a survey with a choice experiment placing operators in forward looking, decision-making scenarios, and capture information on past risk management approaches. Evidence regarding a relationship between animal health and output price risk mitigation is mixed and depends on the decision being made. Combined, these results provide new insight into how managers approach multiple risks when facing resource constraints.

Abstract:

In this article we study the long time behaviour of a class of stochastic differential equations introduced in the theory of measurements continuous in time for quantum open systems. Such equations give the time evolution of the a posteriori states for a system underlying a continual measurement. First of all we give conditions for the equation to preserve pure states and then, in the case of a finite-dimensional Hilbert space, we obtain sufficient conditions from which the stochastic equation for a posteriori states is ensured to map, for t → +∞, mixed states into pure ones. Finally we study existence and uniqueness of an invariant measure for the equations which preserve pure states. We give a general theorem for the purely diffusive case, again in the finite-dimensional case; we then apply it to some physical examples. For the purely jump case, an example is discussed in which the invariant measure exists and is unique.

Full text

Abstract:

Options for a new definition of, and key for, rainforest in Australia are provided. The definitions take a national perspective, and are based on the ecological characteristics of rainforest species and some structural and floristic characteristics. Rainforest plant species are defined as those adapted to regenerating under low-light conditions experienced under the closed canopy or in localised gaps caused by recurring disturbances which are part of the natural rainforest ecosystem, and are not dependent on fire for successful regeneration. Three definitions are provided which differ in the extent of inclusion of transitional and seral communities. The first definition recognises communities such as mixed forests as transitional to rainforests and therefore as separate communities. The second definition includes a minimal component of emergent non-rainforest species in rainforest in the recognition that the main floristic component and functioning of the communities cannot be distinguished. The third definition includes the late successional stages of transitional and seral communities in rainforest on the presumption that such communities include non-rainforest species which are close to senescence, and that these communities are essential for the long-term conservation of rainforest in areas where rainforest is vulnerable and subject to major disturbance, particularly by fire. The first definition is concluded to be the least ambiguous and arbitrary, and enables a consistent approach to rainforest management. Recognition of mixed forests as a distinctive and mappable vegetation type should be incorporated in a comprehensive conservation strategy inclusive of all ecosystem developmental stages.

Abstract:

The growth of global population and economy continually increases the waste volumes and consequently creates challenges to handle and dispose solid wastes. It becomes more challenging in mixed rural-urban areas (i.e., areas of mixed land use for rural and urban purposes) where both agricultural waste (e.g., manure) and municipal solid waste are generated. The efficiency and confidence of decisions in current management practices significantly rely on the accurate information and subjective judgments, which are usually compromised by uncertainties. This study proposed a resource-oriented solid waste management system for mixed rural-urban areas. The system is featured by a novel Monte Carlo simulation-based fuzzy programming approach. The developed system was tested by a real-world case with consideration of various resource-oriented treatment technologies and the associated uncertainties. The modeling results indicated that the community-based bio-coal and household-based CH4facilities were necessary and would become predominant in the waste management system. The 95% confidence intervals of waste loadings to the CH4and bio-coal facilities were 387, 450 and 178, 215 tonne/day (mixed flow), respectively. In general, the developed system has high capability in supporting solid waste management for mixed rural-urban areas in a cost-efficient and sustainable manner under uncertainty.

Abstract:

An accurate description of composite geomembrane-cushion interface behavior is of great importance for stress-deformation analysis and stability assessment of geomembrane surface barrier of rock-fill dam. A series of direct shear tests were conducted to investigate the friction behaviors of interfaces between composite geomembrane and two different permeable cushion materials (crushed stones and polyurethane mixed crushed stones). The shear stress-displacement relationships of the two interfaces show different characteristics and were described by the nonlinear-elastic model and nonlinear-elastic perfectly plastic model, respectively. Then the two models were implemented into the Fast Lagrangian Analysis of Continua in Three Dimensions (FLAC3D) procedure correctly. By verification of a numerical example, numerical calculation results showed a good agreement with the theoretical solutions and test results.

Abstract:

This study provides an empirical assessment of the United Kingdom (UK) manufacturing small and medium-sized enterprises (MSMEs) sector, exploring the impact of environmental turbulence specific to the post–Great Recession (2008) era on changes to the way manufacturing strategy is formulated and implemented. The study identifies changes to the frequency, fluidity, formality and focus of manufacturing strategy review and how the various business functions play a changing role in contributing to this strategic process. A mixed-methods research approach is applied, incorporating a survey of 104 UK-based manufacturing SMEs supported by 17 in-depth interviews with senior managers. The research uses a parallel mixed analysis of the two data sources, thereby offering an alternative to the mono-quantitative approaches to manufacturing research that have dominated. The findings show that during, and emerging from, the post–Great Recession environment, the majority of manufacturing SMEs employ a fluid, highly frequent approach to manufacturing strategy review with increasing contributions from their marketing, sales and finance business functions driven predominantly by function-specific response to changes in the external environment, although internal drivers sill influence high-level strategy, finance and human resources. The implications of the study to theory, practice and general management suggest that the MSME sector is dominated by organizations experiencing continual impact from the external environment.

Abstract:

Expansive soils encountered in North Texas exhibit low strength properties, as well as high swell and shrinkage characteristics. These soil properties often result in the poor performance of pavement infrastructures, particularly those built for low-volume traffic conditions. Pavement distress caused by differential heaving leads to pavement cracking and ponding problems. This causes riding discomfort for commuters and induces traffic delays due to the continual repair of the pavements. Hence, it is necessary to explore and develop new and alternate stabilization methods to improve stabilization of expansive soils. Laboratory investigations were designed and conducted on four local expansive soils stabilized with low-calcium Class F fly ash, Type V sulfate-resistant cement, ground granulated blast furnace slag (GGBFS), and lime mixed with fibers. Test results were analyzed and ranked by well-established scales to select the top-performing stabilizers. Results showed that the sulfate-resistant cement, followed by the lime with fibers and the GGBFS stabilization methods, provided effective stabilization of soft and expansive soils. Ranking assessments were performed, and a few important conclusions on stabilization mechanisms were drawn.
