Many-body localization and transition by density matrix renormalization group and exact diagonalization studies

A many-body localized (MBL) state is a new state of matter emerging in a disordered interacting system at high energy densities through a disorder driven dynamic phase transition. The nature of the phase transition and the evolution of the MBL phase near the transition are the focus of intense theoretical studies with open issues in the field. We develop an entanglement density matrix renormalization group (En-DMRG) algorithm to accurately target the entanglement patterns of highly excited states for MBL systems. By studying the one dimensional Heisenberg spin chain in a random field, we demonstrate the high accuracy of the method in obtaining statistical results of quantum states in the MBL phase. Based on large system simulations by En-DMRG for excited states, we demonstrate some interesting features in the entanglement entropy distribution function, which is characterized by two peaks; one at zero and another one at the quantized entropy $S=ln2$ with an exponential decay tail on the $S>ln2$ side. Combining En-DMRG with exact diagonalization simulations, we demonstrate that the transition from the MBL phase to the delocalized ergodic phase is driven by rare events where the locally entangled spin pairs develop long-range power-law correlations. The corresponding phase diagram contains an intermediate regime, which has power-law spin-z correlations resulting from contributions of the rare events. We discuss the physical picture for the numerical observations in the intermediate regime, where various distribution functions are distinctly different from results deep in the ergodic and MBL phases for finite-size systems. Our results may provide new insights for understanding the phase transition in such systems.
Model Fidelity and Students’ Responses to an Authenticated Unit of Cooperative Learning

A wealth of school-based interventions report on students’ positive responses to the use of models-based practice in physical education. However, research that examines the effectiveness of models-based practice rarely reports on the fidelity of implementation i.e., when all of the characteristics of a model are implemented. The purpose of this study was to explore model fidelity in the use of the Cooperative Learning model. Action research and systematic observation (using the Cooperative Learning Validation Tool which acknowledged the observation of key characteristics of the model) were used to confirm model fidelity. Consequently, the themes which emerged from the data analysis of could be directly linked to the authentic use of Cooperative Learning context. The paper concludes by arguing that when reporting on findings from empirical research on the use of Cooperative Learning we need to adopt a more robust approach in determining—through rigor and quality of research—the authenticity of implementation.
"Hot" cognition and dual systems: Introduction, criticisms, and ways forward

Models distinguishing two types of processes or systems—typically one more automatic and/or affective-motivational, one more controlled and/or calculating-deliberative—are widespread in psychological science. However, such dual-process (or dual-system) models suffer from various problems and have been substantially criticized recently. In this chapter, we discuss these types of models, attempt to clarify terminology, discuss recent critiques at both empirical and theoretical levels, and suggest a more mechanistic explanation grounded in physiology and reinforcement learning of what makes "hot" processes hot. We discuss success stories and challenges related to these types of models in two illustrative fields, addiction and adolescent risk taking. Finally, we outline the basic ideas behind our R3 model—a reprocessing model grounded in reinforcement learning that conceptualizes levels of reflectivity as emergent states of one single system, rather than a separate process or system—as a possible way forward to address and overcome problems of dual-process models.
Vegetation and water yield dynamics in an Edwards Plateau watershed

Woody cover, when expressed at the scale of the 207 km2 Cusenbary Draw basin, remained unchanged (approximately 23%) from 1955 to 1990. When expressed at the scale of range sites, woody cover declined on sites with relatively high production potential and increased on sites with relatively low production potential. Change in woody cover distribution at sub-range site scales, increased low and high woody covers and decreased intermediate woody cover, would be expected to lead to increased water yield at the basin scale because there was an apparent threshold woody cover (approximately 20%) above which simulated evapotranspiration (ET) changed little with increasing woody cover. This potential increase, however, was more than offset by the decreased water yield due to increased ET loss associated with compositional changes of woody vegetation from oak to juniper. A set of woody cover-ET regression curves was developed for different range sites based on simulation studies using the SPUR-91 hydrologic model. Based on these woody cover-ET regression curves and GIS analysis, no brush management would result in a 35% decrease in water yield, while a hypothetical brush management cost-share program would increase water yield by 43% over the 1990 level. Benefits in water yield and forage production from brush management differ in different range sites. A brush management cost-share program that preferentially allocated brush management to sites with deep soil and the highest forage production potential increased water yield by 50%, compared to a 100% increase if brush management were preferentially allocated on sites with shallow soil and highest water yield potential. These model results illustrate that the spatial scale of assessment and spatial distribution of brush management among range sites should be important concerns associated with developing and evaluating brush management policies.

The influence of transformational and transactional leadership on dyadic trust relationships through perceptions of fairness

Leadership and interpersonal trust are critical issues for the survival of organisations. Both aspects have been researched thoroughly, but the role organisational justice might play in this relationship has been largely ignored. The purpose of this study was to investigate the relationship between transformational and transactional leadership and interpersonal trust, and whether organisational justice plays a mediating role. Through LISREL analysis, it was found that interactional justice played a greater role in the relationship between transformational leadership and trust than procedural justice. Distributive justice mediated the relationship between transactional leadership and trust.
Life-Cycle Variations in the Association Between Current and Lifetime Income: Country, Cohort and Gender Comparisons

This study applies Haider and Solon’s (2005) generalized errors-in-variables model to Swedish income tax data in order to produce estimates of the association between current and lifetime income. Our estimates of this association demonstrate strong life-cycle patterns. This implies that the widespread use of current income as a proxy for lifetime income (following the standard errors-in-variables model) leads to inconsistent parameter estimates (a.k.a. life-cycle bias). Estimates for comparable cohorts of Swedish and American men demonstrate surprising similarities. There are, however, significant gender and cohort differences in this association which, in turn, lead to statistically significant and quantitatively meaningful differences in life-cycle biases. The results from this study can aid the applied researcher in analyzing and correcting for life-cycle bias.
Filling data gaps on the diversity and distribution of Amazonian bats (Chiroptera): the case of Amapá, easternmost Brazil

Brazil is the second most bat species-rich country in the world, but the information on its species diversity, occurrence and distribution is still heterogeneous and fragmented. None of the Brazilian biomes are well surveyed for bats, but this situation is more critical in Amazonia, an area covering nearly 2/3 of the country. Here we provide updated information on the bats of Amapa, once a data gap in the diversity and distribution of bats in the easternmost Amazonia, and the Guiana Shield as well. Rapid biological assessments (5,551 mistnet.hours) were conducted in conservation units and areas of concern, resulting in 1,695 captures, 59 species, 36 genera and six families for the State. New records for the state and for the Guiana Shield area are reported. With our records, 82 species of bats are currently known in Amapa, filling a gap in the knowledge of bat fauna in the Amazon River's delta region.
From 'Event-led' to 'Event-themed' Regeneration: The 2002 Commonwealth Games Legacy Programme

Hosting large events has long been associated with the physical regeneration of cities. To supplement these 'hard' impacts, cities are now attempting to use events to stimulate 'softer' social and economic regeneration. This paper evaluates the impacts of the Legacy Programme adopted in conjunction with the 2002 Commonwealth Games held in Manchester, UK. Alongside its emphasis on social and economic regeneration, this programme was unusual in that the projects were games-themed, rather than being directly linked to the event. Despite some concerns about the organisational structures employed and the sustainability of impacts, target beneficiaries have received valuable assistance from the programme. Thus it appears that there are valuable lessons that other cities can learn from this example of event-themed regeneration.
Species composition, diversity and structure of secondary tropical forests following selective logging in Huong Son, Ha Tinh Province, Vietnam

composition of families and number of commercial species found in the plot PL2 were lower in comparison with those of the two other plots. The medium Sorensen similarity index, ranging from 29.55 to 40.250/0, found for all tree size classes showed a slightly high dissimilarity between plots. Simpson's index for all tree size classes was quite similar among plots though only small difference was found for seedlings in the plot PL2. Shannon-Wiener index (H') in all plots exhibited relatively high, ranging from 1.76 to 3.48, for all size classes combined but revealed slightly low diversity indices for commercial species. Species richness and evenness (H) turned out to be the best indices for demonstrating diversity among plots. The size class distribution with Weibull model showed nearly a continuously inverse J-shaped curve. Except the plot PL2 and the plot PL12 followed a similarly exponential trend, the plot PL22 showed a left skewed shape. However, the result of basal area showed that the PL12 had lower basal area than others. AJI plots showed having some commercial species with relatively high importance value index along with a proportion contributed by other noncommercial ones, i.e. Syz~/gium cinereum and Diospyros apiculata.
Hawking Temperature of the Reissner-Nordstrom-Vaidya

We have derived the Hawking temperature of the Reis sn rNordstrom-Vaidya black hole by the use of both the radial null geodesic and the complex path methods. We have obtained that the mas s dependence of the temperature in the Reissner-Nordstrom-Vaidya black hole is not as simple as that in the Schwarzschild black hole, but still we regai n the conclusion, as in the case of the Schwarzschild black hole, that a higher Hawk ing temperature corresponds to a lower mass of a black hole.
Levels of participation in ICT training programmes, computer anxiety and ICT utilization among selected professionals

Information and Communication Technology (ICT) no doubt has improved the quality of life in the modern world and it is widely used by many professionals in carrying out their daily activities. Many organizations invest so much in training their workers on ICT applications. It is expected that training programmes will reduce computer anxiety and improve workers’ ICT utilization and productivity. This study therefore assessed the levels of participation in ICT training programmes, computer anxiety and ICT utilization among professionals in Ogun State Nigeria. The relationships among these variables were also investigated. A stratified random sample technique was used to select four hundred and seventy seven respondents from four different professions in Ogun State, Nigeria namely teaching, broadcasting, medical and banking. Bank workers use ICT most and are also least anxious about computers. There is a significant positive relationship between levels of participation in ICT programmes and computer utilization (r=+0.755, p<0.05). Organisations should do more to invest in ICT training so as to enhance productivity.
Genetics polymorphism of poplars from Moscow region based on high-throughput sequencing of ITS

Poplars are widely used in landscaping of Moscow due to the ability to effectively purify the air from harmful impurities and to release a large amount of oxygen. The genusPopulusis characterized by a high level of intraspecies polymorphism, as well as the presence of natural interspecies hybrids. The aim of our work was to evaluate the genetic diversity of poplars, which are growing on the territory of Moscow city by high-throughput sequencing of internal transcribed spacers of 45S rRNA genes (ITS sequences). Sequencing of ITS of 40 poplar plants was performed on Illumina platform (MiSeq) and about 3 000 reads were obtained for each sample in average. Bioinformatics analysis was performed using CLC Genomics Workbench tool. The involved set of poplars had a high level of genetic diversity – the number of single nucleotide polymorphisms (SNPs) detected in each genotype relative to the reference ITS1 and ITS2 sequences ofP. trichocarpavarying from 4 to 44. We showed that even trees which had been planted on the same territory and, probably, at the same time had significant genetic differences. It can be speculated that highly polymorphic plant material was used for planting poplars in Moscow. For some sites with SNPs, several variants of nucleotides were found in the same individual and the ratio of SNPs was different. We assume that close to 50/50 ratio is observed in interspecific hybrids due to genetic differences in the ITS sequences between maternal and paternal genotypes. For SNPs with a predominance of one of the variants, the presence of paralogues among numerous genomic copies of ITS sequences is more likely. The results of our work can provide a framework for molecular genetic markers application with the purpose ofPopulusspecies and interspecific hybrids identification, determination the origin of a number of natural hybrids, and monitoring the diversity of genusPopulusin the Moscow city.
In vitro regeneration study in lablab bean and dolichos bean (Lablab purpureus (L). Sweet) Genotypes

The current investigation was carried out to study in vitro regeneration potential in Lablab bean genotypes and Dolichos bean Cv. (Konkan Bhushan). In surface sterilization, treatment with 70% alcohol for 5 minute followed by HgCl2 (0.1%) for 10 minutes was found the most effective in establishing aseptic cultures (97.22%). Mature embryo axis with single cotyledon (MEASC) explant on medium MS+ 6 mg/l BAP+ 0.5 mg/l NAA responded well for shoot induction frequency, multiple shoot induction in Dolichos bean genotype ‘Konkan Bhushan’. The medium MS+ 0.5mg/l BAP+ 0.2 mg/l GA3 was found better for elongation of in vitro regenerated shoots. The genotype ‘Konkan Bhushan’ rooted also earliest in 9.30 days on medium MS+ 1.0 mg/l IBA+ 2% sucrose with highest root induction frequency (79.51%) and maximum roots per shoot (5.04). During hardening, the potting mixture of soil, vermiculite and sand in 1:1:1 showed the highest survival rate.
Heavy metals in soil and vegetables grown with municipal wastewater in Lahore

Heavy metals contamination of fruits and vegetables as a consequence of wastewater irrigation is most important concern today. Present study measures heavy metals concentration (Cr, Cu and Pb) in soil and vegetable samples collected from agriculture area around four major drains of Lahore (Hudiara drain, BabuSabu drain, Chota Ravi drain and Kharak drain). Results show that concentration of Cu, Cr and Pb in soil samples were in compliance with WHO and EU standards, with an average of 2.221 ± 1.184, 5.314 ± 1.0511 and 3.864 ± 1.6095 mg/kg respectively. Cu content in vegetables ranged from 0.4-18.9 mg/Kg (average of 4.11 ± 6.639 mg/kg), was within limits while Cr in Lady Finger, from Chota Ravi drain area, was 13.2 mg/Kg which is higher than permissible limit (2.4 mg/Kg). While Pb concentration in vegetables samples varied between 0.7 -8.1 mg/Kg (Mean 2.329 ± 2.592 mg/kg), which was also higher than the standard (0.3 mg/Kg). Bangladesh J. Sci. Ind. Res. 52(4) , 331-336, 2017
Mechanical and durability properties of a soil stabilised with an alkali-activated cement

Alkali-activated cements (AAC) have been extensively studied for different applications as an alternative to Portland cement (which has a high carbon footprint) and due to the possibility of including waste materials such fly ash or slags. However, few works have addressed the topic of stabilised soils with AAC for unpaved roads, with curing at ambient temperature, where the resistance to wetting and drying (WD) as well as the mechanical properties evolution over time is particularly relevant. In this paper, silty sand was stabilised with an AAC synthesised from low calcium fly ash and an alkaline solution made from sodium silicate and sodium hydroxide. The evolution of stiffness and strength up to 360 days, the tensile strength, and the performance during WD cycles were some of the characteristics analysed. Strength and stiffness results show a significant evolution far beyond the 28th curing day, but still with a reasonable short-term strength. Strength parameters deduced from triaxial tests were found to be very high with stress–strain behaviour typical of cemented soils. Durability properties related to resistance to immersion and WD cycles were found to comply with existing specifications for soil–cement, giving validity for its use as soil–cement replacement.
IMC antecedents and the consequences of planned brand identity in higher education

Purpose This study aims to identify integrated marketing communication (IMC) antecedents and the consequences of planned brand identity in the context of higher education, and empirically test a number of hypotheses related to the constructs of these antecedents and consequences. Design/methodology/approach A model of the IMC antecedents and consequences of planned brand identity was tested in a survey conducted among stakeholders in two London-based universities. Structural equation modelling (SEM) was applied to gain insight into the various influences and relationships. Findings The study identifies and confirms key constructs in planned brand identity. IMC antecedents of planned brand identity, such as brand elements, service attributes, public relations and place/country of origin, were found to positively influence the planned brand identity consequences of awareness, image and reputation. However, websites, social media, advertising and direct marketing were not found to have significant influence. Research limitations/implications The focus on two UK universities limits the generalisability of the findings. Future research should be conducted in other country settings to test the relationships identified in the present study. Also, future research may build on the study’s findings by investigating the attitudinal and behavioural consequences of brand identification in the higher education context. Practical implications Professionals responsible for universities’ promotional and branding activities need to evaluate the relative contributions of the IMC antecedents of planned brand identity. Brand elements such as design, colour and name, for example, should be reviewed to determine whether modifications are required in different international markets. The increasing prevalence of social media, one of the key antecedents of brand awareness, offers opportunities for universities to engage in brand co-creation by interacting with past, present and future students on relevant digital platforms. Finally, the place/country-of-origin cue is of particular relevance to institutions of higher education given the increasing numbers of students at both undergraduate and postgraduate levels who are choosing to study abroad (Melewar and Akel, 2005). The attraction of the UK as a country to study in, or the appeal of individual cities such as London, should be fully integrated into universities’ IMC strategies. Originality/value The study makes two main contributions. First is the theoretical contribution by identifying the core IMC antecedents and consequences of planned brand identity for universities and from this extrapolate key directions for future research. Second it is indicated that a number of managerial implications are designed to assist in the formulation of improved professional practice.
Quantitative, Qualitative or Mixed Research: Which Research Paradigm to Use?

Abstract Research students usually encounter great difficulties in setting up a viable research project mainly because, on the one hand they lack familiarity with the philosophical underpinnings of major paradigms used in educational research: quantitative, qualitative or mixed, and on the other hand , they do not associate the corresponding research types with these paradigms : experimental, non experimental for the former, and interactive or non interactive for the second and the for the latter whether it is explanatory or exploratory, in addition to the importance of triangulation in any research study . These paradigms determine not only the formulation of the problem chosen for research and the associated research questions or hypothesis but also and more importantly, the sampling procedure as well as the selection of the appropriate research tools and the way the collected data is analysed and discussed. This survey of the major paradigms in educational research and their implications for the design of any research study will hopefully provide them with the necessary guidance to approach their research project with more confidence et more efficiency.
