Structure and physical properties of paracrystalline atomistic models of amorphous silicon

We have examined the structure and physical properties of paracrystalline molecular dynamics models of amorphous silicon. Simulations from these models show qualitative agreement with the results of recent mesoscale fluctuation electron microscopy experiments on amorphous silicon and germanium. Such agreement is not found in simulations from continuous random network models. The paracrystalline models consist of topologically crystalline grains which are strongly strained and a disordered matrix between them. We present extensive structural and topological characterization of the medium range order present in the paracrystalline models and examine their physical properties, such as the vibrational density of states, Raman spectra, and electron density of states. We show by direct simulation that the ratio of the transverse acoustic mode to transverse optical mode intensities ITA/ITO in the vibrational density of states and the Raman spectrum can provide a measure of medium range order. In general, we conc.
Thermal simulation and economic assessment of unglazed transpired collector systems

Unglazed transpired collectors (UTCs) have recently emerged as a new solar air heating technology. They are relatively inexpensive, efficient, and particularly suited to applications in which a high outdoor air requirement must be met. A TRNSYS model has been created for UTC systems. Annual simulations are performed for several representative buildings. The statewide economic potential of UTC systems is assessed for Wisconsin. UTC systems on existing buildings are competitive with electric heating systems but not with gas or oil heating. Electric heating is not widely used in most buildings that are well-suited for UTC systems, with the exception of large apartment buildings. Therefore, there is no significant statewide economic potential for retrofit of UTC systems on existing buildings except in the residential sector. However, UTC systems are cost effective for new buildings because their low first cost allows them to compete with gas and oil heating.
The relation between teachers’ interpersonal role identity and their self-efficacy, burnout and work engagement

ABSTRACT This study investigated the relation between teachers’ interpersonal role identity on the one hand and teachers’ self-efficacy, burnout and work engagement on the other. Data was collected using questionnaires and semi-structured and video-stimulated interviews. Results especially showed differences for self-efficacy between the teachers’ interpersonal role identities. The results indicate that teacher educators and coaches at schools can support (student) teachers (1) by helping them to discover and making them aware of their interpersonal identity standard and (2) by facilitating their growth towards a match between their interpersonal identity standard and their appraisal of classroom situations.
Hydroxylamine (NH 2 OH) in the Baltic Sea

The vertical distribution of dissolved hydroxylamine (NH 2 OH) was measured for the first time at 10 stations in the western, southern and central Baltic Sea during a cruise in February 2004. The distribution of dissolved NH 2 OH was complex due to the interplay of in-situ production in the shallow western and southern Baltic Sea and the hydrographical setting in the central Baltic Sea caused by the major North Sea water inflow event in January 2003. We conclude that nitrification might be the major source of NH 2 OH, whereas anaerobic ammonium oxidation (anammox) appeared to be negligible. We suggest that a "fresh" nitrifying system, in which the NH + 4 -oxidation rates exceeded the NO ? 2 -oxidation rates, favoured the build-up of NH 2 OH.
Perceived Stress as a Mediator between Social Support, Religiosity, and Flourishing among Older Adults

This study was designed to examine the relationships between social support, perceived stress, religiosity, and flourishing and to test the mediating role of perceived stress in the relationships between social support and religiosity with flourishing. This study also examines the moderating roles of religiosity and gender in the relationship between social support and flourishing among 2301 Malaysian older adults. Structural Equation Modelling showed that older adults with high levels of social support, high levels of intrinsic religious motivation, high levels of extrinsic religious motivation, and low levels of perceived stress were more likely to experience flourishing. Bootstrapping analysis provided evidence of perceived stress as a significant partial mediator in the links between social support, intrinsic religious motivation, and extrinsic religious motivation with flourishing. Multi-group analysis revealed that religiosity and gender acted as significant moderators in the links between social support, perceived stress, and flourishing.
Relationship between contractual flexibility and contractor’s cooperative behavior

Purpose Due to the increasing risk and uncertainty of construction projects, contractual flexibility has been considered as an effective tool to cope with emergences and to promote cooperation between owners and contractors. However, in practice, owners often failed to build an efficient cooperative relationship via contracts, resulting in a lacking of appropriate justice. Furthermore, due to a lack of available empirical research, the influence of contractual flexibility on the cooperative behavior of contractors requires further investigation. The purpose of this paper is to fill this gap by conducting empirical research from the perspective of justice perception. Design/methodology/approach A theoretical model was developed and a series of hypotheses were proposed. Then, partial least squares structural equation modeling analyses were conducted on a sample of 188 respondents. Findings The results show that contractual content and executing flexibility both have a positive influence on the cooperative behavior of a contractor, which was partially mediated by distribution, procedural, and interactional justice perceptions. Moreover, content flexibility has a significant impact on all three types of justice perception, and the execution of flexibility has more impact on interactional justice compared to other justice perceptions. Originality/value The findings contribute to an improved understanding of how contractual flexibility affects the cooperative behavior of contractors, indicating that the owner could develop a fair exchange relationship through flexible contracting and motivation of the other party.
Genetic Diversity and Host Specificity Varies across Three Genera of Blood Parasites in Ducks of the Pacific Americas Flyway

Birds of the order Anseriformes, commonly referred to as waterfowl, are frequently infected by Haemosporidia of the genera Haemoproteus, Plasmodium, and Leucocytozoon via dipteran vectors. We analyzed nucleotide sequences of the Cytochrome b (Cytb) gene from parasites of these genera detected in six species of ducks from Alaska and California, USA to characterize the genetic diversity of Haemosporidia infecting waterfowl at two ends of the Pacific Americas Flyway. In addition, parasite Cytb sequences were compared to those available on a public database to investigate specificity of genetic lineages to hosts of the order Anseriformes. Haplotype and nucleotide diversity of Haemoproteus Cytb sequences was lower than was detected for Plasmodium and Leucocytozoon parasites. Although waterfowl are presumed to be infected by only a single species of Leucocytozoon, L. simondi, diversity indices were highest for haplotypes from this genus and sequences formed five distinct clades separated by genetic distances of 4.9%–7.6%, suggesting potential cryptic speciation. All Haemoproteus and Leucocytozoon haplotypes derived from waterfowl samples formed monophyletic clades in phylogenetic analyses and were unique to the order Anseriformes with few exceptions. In contrast, waterfowl-origin Plasmodium haplotypes were identical or closely related to lineages found in other avian orders. Our results suggest a more generalist strategy for Plasmodium parasites infecting North American waterfowl as compared to those of the genera Haemoproteus and Leucocytozoon.
The holographic dual of a SUSY vector model and tensionless open strings

We describe a supersymmetric example of the holographic duality between 3 dimensional vector models and higher spin gauge theories in AdS4, first proposed in a bosonic context by Klebanov and Polyakov. We argue that a particular Fradkin-Vasiliev type supersymmetric higher spin gauge theory in AdS4 with 16 supersymmetries is dual to the singlet sector of bilinear operators of a free = 4, SU(N) vector model defined on the boundary. Starting from the duality between type-IIB on AdS5 × S5 with a D5–brane as an AdS4 × S2 subspace and the 4 dimensional SU(N) SYM with a defect, we recover the duality between our vector model and the higher spin gauge theory. In this case, we propose that the higher spin gauge theory is a truncation of the open string theory on the world volume of the D5-brane in its tensionless string limit. We also comment on a possible Higgs mechanism in our model.
Increased Risk of Hemorrhagic Stroke in Patients with Migraine: A Population-Based Cohort Study

Objective Previous studies on the association between migraine and the risk of developing hemorrhagic stroke (HS) have generated inconsistent results. The aim of the present population-based, age- and sex- matched follow-up study was to investigate whether migraine is associated with an increased risk of HS. Method A total of 20925 persons with at least two ambulatory visits in 2001 with the principal diagnosis of migraine were enrolled in the migraine group. The non-migraine group consisted of 104625, age- and sex- matched, randomly sampled subjects without migraine. The two-year HS-free survival rates for these 2 groups were estimated using the Kaplan-Meier method. Cox proportional hazards regression was used to estimate the effect of migraine on the occurrence of HS. Results During the 2 year follow-up, 113 subjects in the migraine group (0.54%) and 255 in the non-migraine group (0.24%) developed HS. The crude hazard ratio (HR) for developing HS in the migraine group was 2.22 compared to the non-migraine group (95% confidence interval [CI]: 1.78–2.77, p<0.0001) and the adjusted HR was 2.13 (95% CI: 1.71–2.67, p<0.0001) after controlling for demographic characteristics and comorbid medical disorders. Conclusions This population-based age- and sex- matched cohort study shows that migraine was linked to an increased risk of HS.
Evidence-Based Diagnosis, Health Care, and Rehabilitation for Children With Cerebral Palsy

Safer and more effective interventions have been invented for children with cerebral palsy, but the rapid expansion of the evidence base has made keeping up-to-date difficult. Unfortunately, outdated care is being provided. The aims were to survey the questions parents asked neurologists and provide evidence-based answers, using knowledge translation techniques. Parents asked the following questions: (1) what’s wrong with my baby? An algorithm for early diagnosis was proposed. (2) What is cerebral palsy and what online resources are current? Reputable information websites were sourced and hyperlinks provided. (3) The prognosis? Prognostic data from meta-analyses were summarized in an infographic. (4) What interventions offer the most evidence-supported results? Systematic review data about the most effective interventions was mapped into a bubble chart infographic. Finally, (5) What can we expect? Predictors and facilitators of good outcomes were summarized. This article provides an overview of the most up-to-date diagnostic practices and evidence-based intervention options.
Statistical Arbitrage in the U

We study model-driven statistical arbitrage strategies in U.S. equities. Trading signals are generated in two ways: using Principal Component Analysis and using sector ETFs. In both cases, we consider the residuals, or idiosyncratic components of stock returns, and model them as a meanreverting process, which leads naturally to “contrarian” trading signals. The main contribution of the paper is the back-testing and comparison of market-neutral PCAand ETFbased strategies over the broad universe of U.S. equities. Back-testing shows that, after accounting for transaction costs, PCA-based strategies have an average annual Sharpe ratio of 1.44 over the period 1997 to 2007, with a much stronger performances prior to 2003: during 2003-2007, the average Sharpe ratio of PCA-based strategies was only 0.9. On the other hand, strategies based on ETFs achieved a Sharpe ratio of 1.1 from 1997 to 2007, but experience a similar degradation of performance after 2002. We introduce a method to take into account daily trading volume information in the signals (using “trading time” as opposed to calendar time), and observe significant improvements in performance in the case of ETF-based signals. ETF strategies which use volume information achieve a Sharpe ratio of 1.51 from 2003 to 2007. The paper also relates the performance of mean-reversion statistical arbitrage strategies with the stock market cycle. In particular, we study in some detail the performance of the strategies during the liquidity crisis of the summer of 2007. We obtain results which are consistent with Khandani and Lo (2007) and validate their “unwinding” theory for the quant fund drawndown of August 2007.
Store Format Choice in an Evolving Market - A TPB Approach

The store choice has been studied extensively in the literature, but store format choice has had limited research attention. The store choice modeling has been primarily done in the random utility theory framework, which however is a neo-economics based view of choice decision that ignores the psychological and behavioral aspects of this planned behavior. The store format choice for bulk grocery purchase despite being a rational context has not been conceptualized in the most accepted construct in attitude behavior, the Theory of Planned Behavior (TPB). Attitude-behavior linkage has been studied extensively in literature but there is still no consensus on the components of attitude, their interrelationship and resultant impact on conation. The Theory of Reasoned Action has evolved over time to incorporate perceived behavioral control and past behavior to improve its explanatory capacity as TPB; however, it has maintained its unidimensionalist approach and has not tested affect and cognition independently for its impact on behavior. It may therefore be relevant to explore the possibility of testing the proposed Converging framework of Affect and Cognition and comment on the relationship of the structural components of attitude and its impact on format choice. The impact of past behavior on future behavior in Theory of Planned Behavior has been ambiguous while there has not been much emphasis on the quality of past experience. The current research takes up the past experience quality and tests it in the attitude behavior relationship as an antecedent of actual behavior. This paper conceptualizes the store format choice behavior in the Theory of Planned Behavior framework by exploring the strength of attitude-behavior relationship mediated through behavioral intention and its impact on format choice as also the independent role of affect and cognition on the format choice.
Plasma Clusterin and the CLU Gene rs11136000 Variant Are Associated with Mild Cognitive Impairment in Type 2 Diabetic Patients

Objective: Type 2 diabetes mellitus (T2DM) is related to an elevated risk of mild cognitive impairment (MCI). Plasma clusterin is reported associated with the early pathology of Alzheimer's disease (AD) and longitudinal brain atrophy in subjects with MCI. The rs11136000 single nucleotide polymorphism within the clusterin (CLU) gene is also associated with the risk of AD. We aimed to investigate the associations among plasma clusterin, rs11136000 genotype and T2DM-associated MCI. Methods: A total of 231 T2DM patients, including 126 MCI and 105 cognitively healthy controls were enrolled in this study. Demographic parameters were collected and neuropsychological tests were conducted. Plasma clusterin and CLU rs11136000 genotype were examined. Results: Plasma clusterin was significantly higher in MCI patients than in control group (p = 0.007). In subjects with MCI, plasma clusterin level was negatively correlated with Montreal cognitive assessment and auditory verbal learning test_delayed recall scores (p = 0.027 and p = 0.020, respectively). After adjustment for age, educational attainment, and gender, carriers of rs11136000 TT genotype demonstrated reduced risk for MCI compared with the CC genotype carriers (OR = 0.158, χ2 = 4.113, p = 0.043). Multivariable regression model showed that educational attainment, duration of diabetes, high-density lipoprotein cholesterol (HDL-c), and plasma clusterin levels are associated with MCI in T2DM patients. Conclusions: Plasma clusterin was associated with MCI and may reflect a protective response in T2DM patients. TT genotype exhibited a reduced risk of MCI compared to CC genotype. Further investigations should be conducted to determine the role of clusterin in cognitive decline.

Case Studies in Accelerated Experiential Dynamic Psychotherapy (AEDP):Reflections on the Case of "Rosa"

Systematic case studies can benefit understanding of the process and outcome of Accelerated Experiential Dynamic Psychotherapy (AEDP; Fosha, 2000) and other affect-focused and experiential therapies by expanding the scope of investigation from the moment-to-moment emotional change on which these therapies are particularly strong to changes that occur over and across sessions. Systematic case studies are also important because the link between in-session changes and changes in the client behavior and interpersonal relationships in daily life can be explored. In the engaging AEDP case study of "Rosa" (Vigoda Gonzales, 2018), the language switching that allowed Rosa to access painful emotions had an additional relational implication in that the therapist was able to directly connect to Rosa’s child self, which was encoded in a different language than her adult self. I suspect that this prevented Rosa and the therapist from running into difficulties due to the potential mismatch in their backgrounds. Corrective emotional experience seen in this therapy confirmed the finding by my own case study research team (Nakamura & Iwakabe, 2018b) that client therapeutic gains are most clearly reflected in new relationships rather than existing attachment relationships. My commentary concludes with some questions posed to the author relating to the issue of effective training in empathic attunement and working with strong emotions in therapy.
Modeling of the wrinkling of premixed turbulent flames in the thin reaction zones regime for large eddy simulation By

Large eddy simulations (LES) have been successfully applied to premixed turbulent flames in the flamelet regime. However, comparatively little effort to date has focussed on modelling of premixed flames for LES in regimes of combustion in which the small turbulence scales can penetrate the flame, the most important of which is the so-called thin-reaction zones regime. Utilizing concepts of fractal geometry and Damköhler’s limiting flame-speed scalings, this paper proposes a new flame wrinkling model which is intended to be applicable in such regimes. A priori analysis of direct numerical simulations of turbulent, premixed, methane-air slot-jet flames are used to assess the model as well as three literature models of the flame wrinkling. The models are all implemented in a constant coefficient version and in a dynamic version using an approximate Germano identity. We investigated the performance of the models as filter size and downstream distance are varied, and good results are obtained for a range of filter sizes.
Choosing a Conformal Frame in Scalar-Tensor Theories of Gravity with a Cosmological Constant

Cosmological solutions of the Brans-Dicke theory with an added cosmological constant are investigated with an emphasis on selecting a conformal frame in order to implement the scenario of a decaying cosmological constant, featuring an ever-growing scalar field. We focus particularly on the Jordan frame, the original frame with nonminimal coupling, and the conformally transformed Einstein frame without it. For the asymptotic attractor solutions as well as the "hesitation behavior", we find that none of these conformal frames can be accepted as the basis of analyzing primordial nucleosynthesis. As a remedy, we propose to modify the prototype BD theory by introducing a scale-invariant scalar-matter coupling, thus making the Einstein frame acceptable. The invariance is broken as a quantum anomaly effect due to non-gravitational interactions, naturally entailing a fifth force, characterized by a finite force-range and violation of weak equivalence principle (WEP). A tentative estimate shows that the theoretical prediction is roughly consistent with the observational upper bounds. Further efforts to improve experimental accuracy are strongly encouraged.
Site symmetry and crystal symmetry: a spherical tensor analysis

The relation between the properties of a specific crystallographic site and the properties of the full crystal is discussed by using spherical tensors. The concept of spherical tensors is introduced and the way it transforms under the symmetry operations of the site and from site to site is described in detail. The law of spherical tensor coupling is given and illustrated with the example of the electric dipole and quadrupole transitions in x-ray absorption spectroscopy. The main application of the formalism is the reduction of computation time in the calculation of the properties of crystals by band-structure methods. The general approach is illustrated by the examples of substitutional chromium in spinel and substitutional vanadium in garnet.
Improving the Diversity of Spatial Modulation in MISO Channels by Phase Alignment

The performance of spatial modulation (SM) is known to depend on the minimum Euclidean distance in the received SM constellation. In this letter, a symbol scaling technique is proposed for spatial modulation in the multiple-input-single-output (MISO) channel that enhances this minimum distance. It achieves this by aligning the phase of the relevant channels so that the received symbol phases are distributed in uniformly spaced angles in the received SM constellation. In contrast to existing amplitude-phase scaling schemes that are data-dependent and involve an increase in the transmitted signal power for ill conditioned channels, here a phase-only shift is applied. This allows for data-independent, fixed per-antenna scaling and leaves the symbol power unchanged. The results show an improved SM performance and diversity for the proposed scheme compared to existing amplitude-phase scaling techniques.
