Team goal orientation composition, team efficacy, and team performance: The separate roles of team leader and members

Abstract This study aims to examine team goal orientation composition regarding the different roles of a leader’s and team members’ collective goal orientation, and the effects of these on team outcomes. Data included 268 respondents from 64 teams. Results showed team members’ learning goal orientation has positive effect on team performance, mediated by team efficacy. Further, for the role of team leader, the results also revealed the same pattern. Study also showed a leader’s performance goal orientation has negatively related on team performance, mediated by team efficacy. Finally, taking both roles simultaneously, study indicated the interaction between a leader’s and members’ performance goal orientation has negatively related to team efficacy, and the interaction between a leader’s and members’ learning goal orientation has negatively related to team performance. This research contributes to the existing goal orientation theory by taking the different roles of team leader and members into consideration.
Effects of Social Context on State Anxiety, Submissive Behavior, and Perceived Social Task Performance in Females with Social Anxiety

HOWELL, ASHLEY N. , M.S., May 2013, Clinical Psychology Effects of Social Context on State Anxiety, Submissive Behavior, and Perceived Social Task Performance in Females with Social Anxiety Director of Thesis: Justin W. Weeks Self-discrepancy in one’s gender role traits may elicit anxiety and lower selfconfidence in various social contexts for women. Females (n = 52) with elevated social anxiety engaged in both an opinion speech and a semi-structured conversation, with either two separate male or two separate female experimental confederates. It was hypothesized that (a) submissive behavior (i.e., elevated vocal pitch) and (b) state anxiety would be greater, and that (c) self-perceived social performance would be poorer, for participants in the following scenarios: delivering an impromptu speech to a male, versus female, evaluator; and engaging in an impromptu conversation with another female, versus a male. Hypotheses were partially supported. Elevated vocal pitch declined more slowly to baseline vocal pitch for participants in the two scenarios hypothesized to elicit the greatest submissive behavior, versus the alternative two scenarios. Participants reported greater state anxiety and poorer self-perceived social performances when the confederate was a male. Lastly, relationships were tested among the main dependent variables (a-c), trait social anxiety symptoms, gender role trait self-discrepancy, gender role attitudes, self-perceived attractiveness, and estimated menstrual phase status.
GABA Metabolism and Transport: Effects on Synaptic Efficacy

GABAergic inhibition is an important regulator of excitability in neuronal networks. In addition, inhibitory synaptic signals contribute crucially to the organization of spatiotemporal patterns of network activity, especially during coherent oscillations. In order to maintain stable network states, the release of GABA by interneurons must be plastic in timing and amount. This homeostatic regulation is achieved by several pre- and postsynaptic mechanisms and is triggered by various activity-dependent local signals such as excitatory input or ambient levels of neurotransmitters. Here, we review findings on the availability of GABA for release at presynaptic terminals of interneurons. Presynaptic GABA content seems to be an important determinant of inhibitory efficacy and can be differentially regulated by changing synthesis, transport, and degradation of GABA or related molecules. We will discuss the functional impact of such regulations on neuronal network patterns and, finally, point towards pharmacological approaches targeting these processes.
Adolescent Mindfulness Interventions: A Meta-Analysis of the Effects on Anxiety and Depression

Regular and repeated adolescent stress can lead to debilitating conditions such as chronic anxiety and/or depression and both conditions have consequences that impact the present, and the future, of those experiencing clinical anxiety or depression. Anxiety impacts about 20% of the population, and it is the most common mental illness in the United States while an estimated 2.2 million (9.1%) adolescents ages 12-17 in the U.S. had at least one major depressive episode in the past year. Standard treatments for these conditions include combined psychotherapy and medication; however, few medications are approved for adolescent use and have side effects. Alternative therapies are being studied and a therapy style that has seen positive results are mindfulness-based interventions that include the main component of mindfulness meditation. Mindfulness-based treatments have increased, and research into mindfulness has expanded for adolescent populations however, a combined effect had not been determined for anxiety and depression. Through meta-analysis of 13 included studies a small to medium effect size for both adolescent anxiety (g = 0.36) and depression (g = 0.32). Moderator analysis indicates that certain MBIs (ACT and DBT) show greater effect sizes for either anxiety or depression. The results are encouraging but more research in the area of MBIs is needed to determine their viability and cost effectiveness as treatment option for adolescent anxiety and depression. Particular attention should be paid to mindfulness’ application in schools for wide spread instruction and benefits derived by the adolescent participants experiencing stress.

Multivariate Statistical Modeling with Survey Data

We describe an extension of the pseudo maximum likelihood (PML) estimation method developed by Skinner (1989) to multistage strati¯ed cluster sampling designs, including ¯nite population and unequal probability sampling. We conduct simulation studies to evaluate the performance of the proposed estimator. The estimator is also compared to the general estimating equation (GEE) method for linear regression implemented in SUDAAN. We investigate the distribution of the likelihood ratio test (LRT) statistic based on the pseudo log-likelihood value and describe an adjustment that gives correct chi-square distribution. The performance of the adjusted LRT is evaluated with a simulation study based on the Behrens-Fisher problem in a strati¯ed cluster sampling design.
Science Perspectives on Psychological the Power of Testing Memory: Basic Research and Implications for Educational Practice on Behalf Of: Association for Psychological Science the Power of Testing Memory Basic Research and Implications for Educational Practice Perspectives on Psychological Science t

—A powerful way of improving one's memory for material is to be tested on that material. Tests enhance later retention more than additional study of the material, even when tests are given without feedback. This surprising phenomenon is called the testing effect, and although it has been studied by cognitive psychologists sporadically over the years, today there is a renewed effort to learn why testing is effective and to apply testing in educational settings. In this article, we selectively review laboratory studies that reveal the power of testing in improving retention and then turn to studies that demonstrate the basic effects in educational settings. We also consider the related concepts of dynamic testing and formative assessment as other means of using tests to improve learning. Finally, we consider some negative consequences of testing that may occur in certain circumstances, though these negative effects are often small and do not cancel out the large positive effects of testing. Frequent testing in the classroom may boost educational achievement at all levels of education. In contemporary educational circles, the concept of testing has a dubious reputation, and many educators believe that testing is overemphasized in today's schools. By ''testing,'' most commentators mean using standardized tests to assess students. During the 20th century, the educational testing movement produced numerous assessment devices used throughout education systems in most countries, from prekindergarten through graduate school. However, in this review, we discuss primarily the kind of testing that occurs in classrooms or that students engage in while studying (self-testing). Some educators argue that testing in the classroom should be minimized, so that valuable time will not be taken away from classroom instruction. The nadir of testing occurs in college classrooms. In many universities, even the most basic courses have very few tests, and classes with only a midterm exam and a final exam are common. Students do not like to take tests, and teachers and professors do not like to grade them, so the current situation seems propitious to both parties. The traditional perspective of educators is to view tests and examinations as assessment devices to measure what a student knows. Although this is certainly one function of testing, we argue in this article that testing not only measures knowledge, but also changes it, often greatly improving retention of the tested knowledge. Taking a test on material can have a greater positive effect on future retention of …
Objectivity and subjectivity in knowledge management: a review of 20 top articles

In recent years knowledge management (KM) has received increased attention from academics and practitioners. There are several challenges to establishing KM as a separate discipline one of the most central being conceptual plurality. The purpose of this paper is to review and position 20 of the most frequently cited KM articles in management journals. More specifically, this paper classifies the KM publications on the subjectivity‐objectivity continuum, discusses the strengths and weaknesses of the publications drawing from positivism and interpretative philosophies, and further discusses the challenges in KM, and how objectivity and subjectivity can be used to provide both product and process orientations in future research.

Casein Kinase 2 Dependent Phosphorylation of Neprilysin Regulates Receptor Tyrosine Kinase Signaling to Akt

Neprilysin (NEP) is a type II membrane metalloproteinase that cleaves physiologically active peptides at the cell surface thus regulating the local concentration of these peptides available for receptor binding and signal transduction. In addition, the cytoplasmic N-terminal domain of NEP interacts with the phosphatase and tensin homologue deleted on chromosome 10 (PTEN) thereby regulating intracellular signaling via Akt. Thus, NEP serves dual functions in extracellular and intracellular signal transduction. Here, we show that NEP undergoes phosphorylation at serine residue 6 within the N-terminal cytoplasmic domain. In vitro and cell culture experiments demonstrate that Ser 6 is efficiently phosphorylated by protein kinase CK2. The phosphorylation of the cytoplasmic domain of NEP inhibits its interaction with PTEN. Interestingly, expression of a pseudophosphorylated NEP variant (Ser6Asp) abrogates the inhibitory effect of NEP on insulin/insulin-like growth factor-1 (IGF-1) stimulated activation of Akt. Thus, our data demonstrate a regulatory role of CK2 in the interaction of NEP with PTEN and insulin/IGF-1 signaling.
Hurry up and ‘like’ me: immediate feedback on social networking sites and the impact on adolescent girls

ABSTRACT At an age identified as the period with the most intense focus on appearance, and where young girls are establishing their identity, it appears that social networking site (SNS) interactions are playing a pivotal role in determining what is, and what is not, socially endorsed. This paper draws on data obtained during five separate focus group interviews with a total of 28 middle school aged girls from three South Australian schools. Results indicated that feedback from other SNS users was central in the construction of identity and had an impact on self-esteem. It was found that immediate feedback was highly desired in response to images and comments posted on SNSs. It was also found that the immediacy of the feedback directly influenced the emotional state of the study participants. Understanding the impact of SNS communication, specifically pertaining to feedback, can be directly linked to the Australian Curriculum Health and Physical Education key ideas. Furthermore it is relevant to educative practices where schools are sites for technological advancements and positive reinforcement of identity and appearance.
Place attachment, residential satisfaction, and life satisfaction: Traditional and renewed kibbutz

ABSTRACT Economic crisis in the early 1980s, followed by heavy debt, challenged the existence of the kibbutz. In order to prevent disintegration, rigorous privatization-related economic and structural reforms were implemented. In this study, we evaluate if these transformational changes affected the perception and emotional ties of kibbutz members. Specifically, we examined differences between traditional and renewed kibbutz in terms of life satisfaction, place attachment, and residential satisfaction. The results indicated that members of the renewed kibbutz reported higher levels of place attachment than those of the traditional kibbutz. However, no significant differences were observed for residential satisfaction and life satisfaction. Moreover, place attachment and residential satisfaction were significantly associated with life satisfaction. Finally, kibbutz type moderated the indirect effect of residential satisfaction on life satisfaction through place attachment.
Effect of Learning Activity on Students' Motivation, Physical Activity Levels and Effort/Persistence.

The type of learning activity offered in physical education may influence students' motivational beliefs, physical activity participation and effort/persistence in class. However, most empirical studies have focused on the individual level rather than on the learner-content interactions. Accordingly, the potential effects of learning activities on these outcome variables have been overlooked. This study examined whether students' motivational beliefs (self-efficacy and outcome expectancy), moderateto-vigorous physical activity (MVPA) and effort/persistence in physical education classes varied as a function of learning activity (soccer vs. fitness). Participants were 225 students (112 boys, 113 girls) in grades 6-8 from a suburban public school in the Southeastern region of the U.S. Each of the three grade levels incorporated three classes, and 25 participants were randomly selected from each class. Students responded to questionnaires measuring their self-efficacy, outcome expectancy and perceived effort/persistence toward soccer and fitness classes, respectively. Students' MVPA in soccer and fitness classes were measured via Actical accelerometers. The results revealed that students reported higher scores in self-efficacy and outcome expectancy toward fitness than they did toward soccer. However, students exhibited higher MVPA in the soccer classes. Regression analyses yielded that only self-efficacy significantly predicted MVPA, while both self-efficacy and outcome expectancy emerged as predictors of effort/persistence across learning activities. The findings may have significant implications for educational practice. For example, physical educators must consider psychological and physical effects that different learning activities may have on students when designing and implementing physical education programs.
Assessment of writing ability in secondary education: comparison of analytic and holistic scoring systems for use in large-scale assessments

Although writing is an important subject of language teaching in secondary education, it is often neglected in large-scale assessments. We report results of a study with 1,365 German high school students in Grade 8 that was conducted in the context of national monitoring of educational achievement. Student responses on seven different persuasive and informative writing tasks were evaluated with two different scoring systems: (i) analytic scoring with 14 dichotomous criteria capturing specific aspects of content, text structure, and language usage, and (ii) holistic scoring based on a comprehensive rating scale similar to the NAEP Holistic Scoring Guide accompanied by semi-holistic scales for content, style (i.e., language usage and organization), and language correct- ness. We inspected the results of both scoring procedures in terms of inter-rater and intra-rater reliability, dimensionality, and convergence of the scoring results. Attention is also given to the generalizability of the findings across different writing tasks and text genres. The results showed better reliability for the holistic and semi-holistic scales than for most of the analytic criteria. For both scoring systems, content and structural aspects were closely associated whereas language correctness was a clearly distinct dimension. Both scoring systems measured the same latent construct.
Are GRB optical afterglows relatively brighter at high z

The redshift distribution of gamma-ray bursts (GRBs) is strongly biased by selection effects. We investigate, via Monte Carlo simulations, one possible selection effect that may be modifying the Swift GRB redshift distribution. We show how telescope response times to acquire a GRB redshift may, via the Malmquist effect and GRB optical afterglow (OA) brightness distribution, introduce a bias into the average of the observed redshift distribution. It is difficult to reconcile a recently reported correlated trend between telescope response time and average redshifts unless we employ a redshift-dependent OA distribution. Simulations of this selection effect suggest that GRB OAs may have been either intrinsically brighter early in the Universe or suffered less local host galaxy extinction.
Geopolitics of Tourism and Academia in the Holy Land

ABSTRACT The premise for this paper is that tourism scholars researching in Israel and Palestine are, in effect, actors in the geopolitical landscape of the Holy Land. Political tourism is a significant factor in how the Israel–Palestine geopolitical conflict is represented. The current paper provides an analysis of how tourism academics address the situation. A research team of Israeli, Palestinian and a third country origins collaborated to produce a narrative synthesis by systematically reviewing 35 academic papers selected through defined criteria. This approach minimized bias and aimed for analytical robustness and validity. Two main conclusions are derived from the analysis. First, papers tend to focus on the social, touristic and religious aspects of tourism not on the core issues of the geopolitical conflict. Second, the works did not contribute to dialogue between parties but reinforced separateness thus reflecting the political conflict.
“I’m in a good place now”: A case study of empowerment of a combat veteran engaged in peer-led disaster relief

ABSTRACT This qualitative single case study examines the lived experience of empowerment of a combat veteran with posttraumatic stress disorder (PTSD) who engages in volunteer, peer-led disaster response activities with Team Rubicon (TR), a nongovernmental organization. Team Rubicon members utilize unique skill sets of both military veterans and civilian first responders to rapidly deploy response teams to domestic and global emergencies. Minimal research to date disseminates experiences of empowerment among combat veterans. The single case study methodological approach offers a rich descriptive and contextual analysis for exploring implications for mental health stigma reduction in combat veterans through an empowerment lens. The study serves to: provide a preliminary foundation for continued theory building of empowerment in combat veterans through peer-led disaster relief settings, expand research, and offer practical implications for social workers in stigma reduction efforts.
Interferon free therapy with direct acting antivirals for HCV

The current treatment for hepatitis C virus (HCV) genotype 1 chronic infection is the addition of direct‐acting antivirals (DAA) with a protease inhibitor (telaprevir or boceprevir) to the pegylated interferon (PEG‐IFN) plus ribavirin (RBV) regimen. Major progress has been made in the past few years: numerous ongoing trials with different compounds, increasing sustained virological response (SVR) rates with oral regimens and shortened treatment duration. Combinations of antivirals with additive potency that lack cross‐resistance and with a good safety profile may provide new regimens in the future to make HCV the first chronic viral infection to be eradicated worldwide with a finite duration of combination DAA therapy without IFN.
Face recognition with one sample per person based on contourlet

In this paper, a novel algorithm for face recognition with one sample per person is proposed. The proposed algorithm is based on contourlet. Multiple training images for each class are constructed through the decomposition and reconstruction of original training images by contourlet. Thus neighborhood discriminant nearest feature line analysis can be performed on the new database. The experimental results demonstrate the efficiency of the proposed algorithm.
Effects of a Teacher Versus iPad-Facilitated Intervention on the Vocabulary of At-Risk Preschool Children

This study examined the effects of an adapted alternating treatments design (AATD) consisting of teacher-facilitated and iPad-facilitated instruction on at-risk preschool children’s vocabulary. Instruction was provided on 42 verbs, divided equally between treatments, across five participants over the course of 7 weeks. Dependent variables included expressive (i.e., providing a definition) and receptive (i.e., identifying the target verb from a picture menu, and yes/no questions including correct and incorrect definitions of the verb) probes of instructional targets. All five participants demonstrated increases from pretest to posttest in their expressive and receptive understanding of the verbs. Implications for research and practice are provided.
