Chasing joint work: administrators’ efforts to structure teacher collaboration

ABSTRACT Although the benefits of teacher collaboration have been touted, school administrators often struggle to foster productive collaboration at their sites. This study takes a deep dive into teachers’ interactions to understand how administrators’ efforts to engineer collaboration play out in teachers’ relationships. Analysis of qualitative interview and observation data with a social network lens provides a nuanced understanding of teachers’ formal and informal interactions at two schools. Findings make clear why leaders are unlikely to build effective collaborative cultures without noticing and building off of the relationships teachers have built within their existing contexts. Overly regulated meetings impacted both formal and informal relationships between teachers, and productive collaboration during formal meeting time could not be sustained in teachers’ informal networks when other structural obstacles intervened. Few teachers were able to overcome either of these constraints to engage in meaningful collaboration, although the efforts of some provide insight for promoting collaborative cultures. This study provides insights for how leaders might notice and capitalise on existing relationships as well as on sometimes unintended structures to support teachers’ join work.
“Nanny State” Politics: Causal Attributions About Obesity and Support for Regulation

We posit that individuals develop causal stories to explain the world around them, including events, behaviors, and conditions in society. These are narratives that attribute causes to controllable components, such as individual choices, or uncontrollable components, such as broader forces in the environment. We use attribution theory to understand how group identity and individual characteristics may shape causal attributions about obesity. Based on previous empirical findings, we argue that attributions and identity can explain policy preferences. We test our hypotheses using individual-level data from a unique national survey of American adults. Our findings suggest that partisan and weight identities predispose people to make certain attributions about obesity, and these attributions influence policy preferences related to obesity. We suggest policymakers need to consider public attributions about obesity and future research should develop more refined measures of attributions.
Heritable Environmental Variance Causes Nonlinear Relationships Between Traits: Application to Birth Weight and Stillbirth of Pigs

There is recent evidence from laboratory experiments and analysis of livestock populations that not only the phenotype itself, but also its environmental variance, is under genetic control. Little is known about the relationships between the environmental variance of one trait and mean levels of other traits, however. A genetic covariance between these is expected to lead to nonlinearity between them, for example between birth weight and survival of piglets, where animals of extreme weights have lower survival. The objectives were to derive this nonlinear relationship analytically using multiple regression and apply it to data on piglet birth weight and survival. This study provides a framework to study such nonlinear relationships caused by genetic covariance of environmental variance of one trait and the mean of the other. It is shown that positions of phenotypic and genetic optima may differ and that genetic relationships are likely to be more curvilinear than phenotypic relationships, dependent mainly on the environmental correlation between these traits. Genetic correlations may change if the population means change relative to the optimal phenotypes. Data of piglet birth weight and survival show that the presence of nonlinearity can be partly explained by the genetic covariance between environmental variance of birth weight and survival. The framework developed can be used to assess effects of artificial and natural selection on means and variances of traits and the statistical method presented can be used to estimate trade-offs between environmental variance of one trait and mean levels of others.
Runs of Homozygosity Associated with Speech Delay in Autism in a Taiwanese Han Population: Evidence for the Recessive Model

Runs of homozygosity (ROH) may play a role in complex diseases. In the current study, we aimed to test if ROHs are linked to the risk of autism and related language impairment. We analyzed 546,080 SNPs in 315 Han Chinese affected with autism and 1,115 controls. ROH was defined as an extended homozygous haplotype spanning at least 500 kb. Relative extended haplotype homozygosity (REHH) for the trait-associated ROH region was calculated to search for the signature of selection sweeps. Totally, we identified 676 ROH regions. An ROH region on 11q22.3 was significantly associated with speech delay (corrected p = 1.73×10−8). This region contains the NPAT and ATM genes associated with ataxia telangiectasia characterized by language impairment; the CUL5 (culin 5) gene in the same region may modulate the neuronal migration process related to language functions. These three genes are highly expressed in the cerebellum. No evidence for recent positive selection was detected on the core haplotypes in this region. The same ROH region was also nominally significantly associated with speech delay in another independent sample (p = 0.037; combinatorial analysis Stouffer’s z trend = 0.0005). Taken together, our findings suggest that extended recessive loci on 11q22.3 may play a role in language impairment in autism. More research is warranted to investigate if these genes influence speech pathology by perturbing cerebellar functions.
Managing Chinese/western joint ventures: a comparative analysis of the 'interaction and networks' and 'Chinese management' literature

In this paper, two relevant bodies of literature are examined and compared, namely the ‘interaction and networks’ literature (associated primarily with the IMP Group) and ‘Chinese management’ literature. Elements examined include relationships, networks, trust, culture and forms of exchange. The contention of the paper is that both bodies of literature have something to contribute in terms of a theoretical basis for an empirical study of Chinese/western joint ventures.
The Ultrabithorax Hox gene of Drosophila controls haltere size by regulating the Dpp pathway

The halteres and wings of Drosophila are homologous thoracic appendages, which share common positional information provided by signaling pathways. The activity in the haltere discs of the Ultrabithorax (Ubx) Hox gene establishes the differences between these structures, their different size being an obvious one. We show here that Ubx regulates the activity of the Decapentaplegic (Dpp) signaling pathway at different levels, and that this regulation is instrumental in establishing the size difference. Ubx downregulates dpp transcription and reduces Dpp diffusion by repressing the expression of master of thick veins and division abnormally delayed and by increasing the levels of thick veins, one of the Dpp receptors. Our results suggest that modulation in Dpp expression and spread accounts, in part, for the different size of halteres and wings.
Rapid Detection of Agriterrorism via Remote Sensing

There is a growing interest in using multiple sources for automatic target recognition (ATR) applications. One approach is to take multiple, independent observations of a phenomenon and perform a feature level or a decision level fusion for ATR. This paper proposes a method to utilize these types of multi-source fusion techniques to exploit hyperspectral data when only a small number of training pixels are available. Conventional hyperspectral image based ATR techniques project the high dimensional reflectance signature onto a lower dimensional subspace using techniques such as Principal Components Analysis (PCA), Fisher’s linear discriminant analysis (LDA), subspace LDA and stepwise LDA. While some of these techniques attempt to solve the curse of dimensionality, or small sample size problem, these are not necessarily optimal projections. In this paper, we present a divide and conquer approach to address the small sample size problem. The hyperspectral space is partitioned into contiguous subspaces such that the discriminative information within each subspace is maximized, and the statistical dependence between subspaces is minimized. We then treat each subspace as a separate source in a multi-source multi-classifier setup and test various decision fusion schemes to determine their efficacy. Unlike previous approaches which use correlation between variables for band grouping, we study the efficacy of higher order statistical information (using average mutual information) for a bottom up band grouping. We also propose a confidence measure based decision fusion technique, where the weights associated with various classifiers are based on their confidence in recognizing the training data. To this end, training accuracies of all classifiers are used for weight assignment in the fusion process of test pixels. The proposed methods are tested using hyperspectral data with known ground truth, such that the efficacy can be quantitatively measured in terms of target recognition accuracies.
Analysis on Intention of Purchasing Organic Foods by The Undergraduate Students of IPB Using The Theory of Planned Behavior Approach

This study aims to identify factors that can increase the intention of buying organic foods and its implications in the design of organic food marketing strategy. The main model adopts Theory of Planned Behavior. Six variables were used in this study, namely, health awareness, environmental awareness, attitudes toward organic foods, subjective norms, perceptions of behavior control and organic food purchase intentions. The data to test the research model were collected from 140 respondents and were analyzed using statistical structural equation modeling method. The results of the study indicate that health awareness, environmental awareness, attitudes on organic foods, subjective norms and behavior control perceptions significantly influence the intention of buying organic foods. Furthermore, health awareness and environmental awareness have no significant effects on organic food purchase intention. The results of this study then become the basis in designing strategies to build a positive attitude on organic foods, subjective norms, and perceptions of consumer behavior control of organic foods that is by promoting organic foods through online or on certain events, creating new innovations so that the foods look attractive, and broadening market reach for organic food products to be more easily available.Keywords: purchase intention, organic food, SEM-LISREL, marketing strategic, Theory of Planned Behavior
The association between body mass index and academic performance

Objectives: To examine the relation between body mass index (BMI) and the academic performance of students from Taif city, Kingdom of Saudi Arabia (KSA) using the grade point average (GPA). Method: A cross-sectional study that includes students from intermediate and high schools located in Taif city, KSA between April 2014 and June 2015. Height and weight were measured and BMI calculated. Related risk factors including dietary habits, activity, parent’s education, sleeping pattern, and smoking were recorded. Result: A total of 14 schools included 424 students. 24.5% were either overweight or obese. The mean age was 15.44 year, 74.8% of the students were male, 53.8% were high school students, and 83.7% attended public schools. The mean overall GPA was 82.44% and the mean GPA for science subjects was 70.91%. No statically significant difference in the BMI was found between those who achieved >90% of the overall grade compared with those who achieved <90%. Post hoc 1-way-analysis of variance showed that obese students were performing worse in physics than normal weight peers (p=0.049). Students who achieved >90% overall grade are more likely to attend private school (p<0.05), live with their parents (p=0.013), having educated parents (p=0.037), getting optimal sleep (p<0.05), and they rarely eat their food outside their home (p<0.05). Conclusion: There was no correlation between the BMI and school performance, except in physics results where obese students perform worse than normal-weight students.
The Descriptions of Phrasal Verbs in Language Reference Materials

Multi-word units like phrasal verbs (PVs) are very common in English, indicating their usefulness in everyday settings. Despite the importance of PVs in both written and spoken discourse, it was reported that language learners generally have great difficulties in understanding and using this linguistic form due to various factors. However, studies examining the treatment of PVs in language reference materials, which may also contribute to learners’ difficulties in understanding PVs are still lacking. Thus, the present study investigates how language reference materials, in particular those commonly prescribed to Malaysian school learners, address and describe this very common and important linguistic feature. Secondary school prescribed textbooks and two learner dictionaries were examined. All sections in the textbooks and dictionaries entries that discuss the selected common PVs were analyzed. Descriptive analysis was conducted to examine how this particular language form is described by looking at the selection of PVs, as well as information provided with respect to PVs. Results of the present study have revealed a number of useful findings with regard to the selection and description of PVs in both reference materials which to date, have not been found in any other studies in Malaysia, to inform relevant parties for further actions.
Risk assessment in ERP projects using an integrated method

Enterprise resource planning (ERP) projects are very complex tasks, expensive, time-consuming, and risky investments. One of the main reasons for the high ERP project failure rate is that managers don't assess and manage the risks involved in these projects. In addition, they don't know the importance degree for each of these risks. On the other hand, to the best of our knowledge papers proposing specific Risk Management approaches, methodologies and techniques for ERP projects are very limited. Therefore, the aim of this paper is to present a new framework for risk analyze in ERP projects. At first we introduce the main risks retrieved from literature review, affecting the performance of ERP projects. Then, we propose a new integrated framework for evaluating potential risks using Fuzzy Failure Mode and Effect Analysis (FFMEA) and Grey Relational Analysis (GRA) tools. The results indicate which risks are most important and critical in ERP projects. This framework can guide managers during risk quantification and mitigation in order to manage ERP projects better and within the systematic framework.
Targeting p97 to Disrupt Protein Homeostasis in Cancer

Cancer cells are addicted to numerous non-oncogenic traits that enable them to thrive. Proteotoxic stress is one such non-oncogenic trait that is experienced by all tumor cells owing to increased genomic abnormalities and the resulting synthesis and accumulation of non-stoichiometric amounts of cellular proteins. This imbalance in the amounts of proteins ultimately culminates in proteotoxic stress. p97, or valosin-containing protein (VCP), is an ATPase whose function is essential to restore protein homeostasis in the cells. Working in concert with the ubiquitin proteasome system, p97 promotes the retrotranslocation from cellular organelles and/or degradation of misfolded proteins. Consequently, p97 inhibition has emerged as a novel therapeutic target in cancer cells, especially those that have a highly secretory phenotype. This review summarizes our current understanding of the function of p97 in maintaining protein homeostasis and its inhibition with small molecule inhibitors as an emerging strategy to target cancer cells.
Kernel Analysis of Deep Networks

When training deep networks it is common knowledge that an efficient and well generalizing representation of the problem is formed. In this paper we aim to elucidate what makes the emerging representation successful. We analyze the layer-wise evolution of the representation in a deep network by building a sequence of deeper and deeper kernels that subsume the mapping performed by more and more layers of the deep network and measuring how these increasingly complex kernels fit the learning problem. We observe that deep networks create increasingly better representations of the learning problem and that the structure of the deep network controls how fast the representation of the task is formed layer after layer.
Reading Literary Fiction and Theory of Mind: Three Preregistered Replications and Extensions of Kidd and Castano (2013)

Scholars from diverse disciplines have proposed that reading fiction improves intersubjective capacities. Experiments have yielded mixed evidence that reading literary fiction improves performance on the Reading the Mind in the Eyes Test, a test of Theory of Mind. Three preregistered experiments revealed mixed results. Applying the “small telescopes” method developed by Simonsohn revealed two uninformative failures to replicate and one successful replication. On a measure of the importance of intentions to moral judgments, results were more mixed, with one significant effect in the expected direction, one nonsignificant effect, and one significant effect in the unexpected direction. In addition, two experiments yielded support for the exploratory but preregistered hypothesis that characters in popular fiction are perceived as more predictable and stereotypic than those in literary fiction. These findings help clarify the sociocognitive effects of reading literary fiction and refine questions for future research.
Preliminary Measurements of the Cryogenic Dielectric Properties of Water–Ammonia Ices: Implications for Radar Observations of Icy Satellites☆

Abstract I report preliminary measurements of the complex permittivity of frozen aqueous ammonia solutions at liquid nitrogen temperatures, representative of those in the saturnian system. The real part of the dielectric constant of 30% ammonia ice is around 4.5 at near-DC frequencies and at ∼1 MHz, compared with around 3.1 for pure water ice. The loss tangents of ammonia-rich ices seem somewhat (∼50%) higher than those for water ice, for which the few low-temperature experiments to date indicate values comparable with predictions by Thompson and Squyres (1990, Icarus 86, 336–354) and Maetzler (1998, in Solar System Ices (B. Schmitt, C. DeBergh, and M. Festou, Eds.), pp. 241–257, Kluwer Academic, Dordrecht), but considerably higher than models by Chyba et al . (1998, Icarus , in press). Ammonia-rich ice may reconcile the radar and optical appearance of Titan's surface: the detectability of water–ammonia ice on Titan by the Cassini mission and the implications for Titan's origin and evolution are discussed.
The Effects of Squat Exercises in Postures for Toilet Use on Blood Flow Velocity of the Leg Vein

[Purpose] The purpose of this study was to identify the effects of squat exercises performed in toilet-using postures on the blood flow velocity of the lower extremities for the prevention of deep vein thrombosis. [Subjects] The subjects were 28 students who were attending B University in Cheonan. They were divided into a group of 14 subjects of sitting toilet users and a group of 14 subjects of squat toilet users. [Methods] The subjects performed squat exercises in different toilet-using postures and we investigated the changes in blood flow velocity. [Results] The variations in blood flow velocities before and after the exercises showed significant differences in both groups but the differences between the two groups were not significant. [Conclusion] Based on the results of this study, we consider squat exercises are effective at improving the variation in lower-extremity blood flow velocity when using a toilet.
