Stressors and Coping Strategies among Early and Middle Adolescent Premier League Academy Soccer Players: Differences According to Age

The purpose of this study was to examine stressors and coping strategies among early (12–14 years) and middle adolescents (15–18 years). Forty male academy soccer players, aged between 12–18 years (M age = 14.22 years), participated in semi-structured interviews, which were inductively and deductively content analyzed. Findings revealed that middle adolescents reported more stressors than early adolescents and that these two groups experienced both common and different stressors. Early adolescents identified making errors, opponents, team performance, and family as salient stressors. Making errors, team performance, coaches, selection, contracts, social evaluation, and playing at a higher level were more prominent among middle adolescents. Middle adolescents reported a greater number and repertoire of coping strategies than early adolescents, and used more problem- and emotion-focused strategies, but fewer avoidance strategies than early adolescents. Based on these findings, it is recommended that applied practitioners working within soccer academies take into account the players' age when providing psychological support.

Driver Gaze Estimation Without Using Eye Movement

Automated estimation of the allocation of a driver’s visual attention may be a critical component of future Advanced Driver Assistance Systems. In theory, vision-based tracking of the eye can provide a good estimate of gaze location. In practice, eye tracking from video is challenging because of sunglasses, eyeglass reflections, lighting conditions, occlusions, motion blur, and other factors. Estimation of head pose, on the other hand, is robust to many of these effects, but cannot provide as finegrained of a resolution in localizing the gaze. However, for the purpose of keeping the driver safe, it is sufficient to partition gaze into regions. In this effort, we propose a system that extracts facial features and classifies their spatial configuration into six regions in real-time. Our proposed method achieves an average accuracy of 91.4% at an average decision rate of 11 Hz on a dataset of 50 drivers from an on-road study.

When web search fails, searchers become askers: understanding the transition

While Web search has become increasingly effective over the last decade, for many users' needs the required answers may be spread across many documents, or may not exist on the Web at all. Yet, many of these needs could be addressed by asking people via popular Community Question Answering (CQA) services, such as Baidu Knows, Quora, or Yahoo! Answers. In this paper, we perform the first large-scale analysis of how searchers become askers. For this, we study the logs of a major web search engine to trace the transformation of a large number of failed searches into questions posted on a popular CQA site. Specifically, we analyze the characteristics of the queries, and of the patterns of search behavior that precede posting a question; the relationship between the content of the attempted queries and of the posted questions; and the subsequent actions the user performs on the CQA site. Our work develops novel insights into searcher intent and behavior that lead to asking questions to the community, providing a foundation for more effective integration of automated web search and social information seeking.
MicroRNA 223-dependent expression of LMO2 regulates normal erythropoiesis

Erythropoiesis is tightly controlled by transcription factors, one of which is the LIM domain-only protein LMO2, but little is still known of the involvement of microRNAs (miRs) in erythroid cell development. This article shows that miR-223 downregulates the expression of LMO2 and thereby blocks erythroid differentiation. Se related perspective article on page 447. Background MicroRNAs are small non-coding RNAs that regulate gene expression through mRNA degradation or translational inhibition. MicroRNAs are emerging as key regulators of normal hematopoiesis and hematologic malignancies. Several miRNAs are differentially expressed during hematopoiesis and their specific expression regulates key functional proteins involved in hematopoietic lineage differentiation. This study focused on the functional role of microRNA-223 (miR-223) on erythroid differentiation. Design and Methods Purified cord blood CD34+ hematopoietic progenitor cells were grown in strictly controlled conditions in the presence of saturating dosage of erythropoietin to selectively induce erythroid differentiation. The effects of enforced expression of miR-223 in unilin-eage erythroid cultures were evaluated in liquid phase culture experiments and clonogenic studies. Results In unilineage erythroid culture of cord blood CD34+ hematopoietic progenitor cells miR-223 is down-regulated, whereas LMO2, an essential protein for erythroid differentiation, is up-regulated. Functional studies showed that enforced expression of miR-223 reduces the mRNA and protein levels of LMO2, by binding to LMO2 3’ UTR, and impairs differentiation of erythroid cells. Accordingly, knockdown of LMO2 by short interfering RNA mimics the action of miR-223. Furthermore, hematopoietic progenitor cells transduced with miR-223 showed a significant reduction of their erythroid clonogenic capacity, suggesting that downmodulation of this miRNA is required for erythroid progenitor recruitment and commitment. Conclusions These results show that the decline of miR-223 is an important event for erythroid differentiation that leads to the expansion of erythroblast cells at least partially mediated by unblocking LMO2 protein expression.
Distantly related sequences in the alpha‐ and beta‐subunits of ATP synthase, myosin, kinases and other ATP‐requiring enzymes and a common nucleotide binding fold.

The alpha‐ and beta‐subunits of membrane‐bound ATP synthase complex bind ATP and ADP: beta contributes to catalytic sites, and alpha may be involved in regulation of ATP synthase activity. The sequences of beta‐subunits are highly conserved in Escherichia coli and bovine mitochondria. Also alpha and beta are weakly homologous to each other throughout most of their amino acid sequences, suggesting that they have common functions in catalysis. Related sequences in both alpha and beta and in other enzymes that bind ATP or ADP in catalysis, notably myosin, phosphofructokinase, and adenylate kinase, help to identify regions contributing to an adenine nucleotide binding fold in both ATP synthase subunits.
Science as practice and culture

Science as Practice and Culture explores one of the newest and most controversial developments within the rapidly changing field of science studies: the move toward studying scientific practice--the work of doing science--and the associated move toward studying scientific culture, understood as the field of resources that practice operates in and on. Andrew Pickering has invited leading historians, philosophers, sociologists, and anthropologists of science to prepare original essays for this volume. The essays range over the physical and biological sciences and mathematics, and are divided into two parts. In part I, the contributors map out a coherent set of perspectives on scientific practice and culture, and relate their analyses to central topics in the philosophy of science such as realism, relativism, and incommensurability. The essays in part II seek to delineate the study of science as practice in arguments across its borders with the sociology of scientific knowledge, social epistemology, and reflexive ethnography.
3DBlogosphere: A Multi-synchronous Approach of Virtual Worlds to Sustain Companywide Communication

—In this paper we consider an industry use case of collaboration: companywide communication within Siemens AG, in contrast to the traditional CSCW interest for small team collaboration. We argue that some features of Virtual Worlds sustain this kind of scenario better than traditional synchronous communication mean. A methodology to create this class of applications is proposed based on the principles of multi-synchronous communication and of mapping web pages into the virtual environment. We describe a prototype application based on those principles, the 3D Blogosphere.
Faculty development through an educational action programme

A number of countries, including Sweden, are reconsidering traditional teaching and learning methods in higher education. This article describes the work of implementing an Educational Action Programme to support faculty development. The work has been organized by an educational developer at the Educational Development Unit (EDU). Representatives of six university departments and the library have participated in cooperation with the EDU on five occasions during one year. The result confirms the value of making one’s colleagues aware of the action programme. In this process the unit head plays an important supportive role. The value of forming local work teams is emphasized, as is the need for continuous documentation of the work. One strategy that has become a model for the implementation work is, first, to raise awareness of the educational action programme and, then, invite participation and exchange among colleagues, which in turn leads to responsibility and long‐term strategic planning.
Why Do You Believe in God? Relationships between Religious Belief, Analytic Thinking, Mentalizing and Moral Concern

Prior work has established that analytic thinking is associated with disbelief in God, whereas religious and spiritual beliefs have been positively linked to social and emotional cognition. However, social and emotional cognition can be subdivided into a number of distinct dimensions, and some work suggests that analytic thinking is in tension with some aspects of social-emotional cognition. This leaves open two questions. First, is belief linked to social and emotional cognition in general, or a specific dimension in particular? Second, does the negative relationship between belief and analytic thinking still hold after relationships with social and emotional cognition are taken into account? We report eight hypothesis-driven studies which examine these questions. These studies are guided by a theoretical model which focuses on the distinct social and emotional processing deficits associated with autism spectrum disorders (mentalizing) and psychopathy (moral concern). To our knowledge no other study has investigated both of these dimensions of social and emotion cognition alongside analytic thinking. We find that religious belief is robustly positively associated with moral concern (4 measures), and that at least part of the negative association between belief and analytic thinking (2 measures) can be explained by a negative correlation between moral concern and analytic thinking. Using nine different measures of mentalizing, we found no evidence of a relationship between mentalizing and religious or spiritual belief. These findings challenge the theoretical view that religious and spiritual beliefs are linked to the perception of agency, and suggest that gender differences in religious belief can be explained by differences in moral concern. These findings are consistent with the opposing domains hypothesis, according to which brain areas associated with moral concern and analytic thinking are in tension.
Calculation of current distribution in transformer windings

The calculation of current distribution in transformer windings is essential for calculation of losses, temperature rise, short circuit stresses and so on. An important case is the calculation of the current distribution in a Y-/spl Delta/ transformer in the case of a line-to-line short circuit of the /spl Delta/ side. The transformer with a tertiary winding in YY/spl Delta/ connection, with the possibility of feeding from both Y sides, is another interesting case. It is well known that the short circuit current in the case of a line-to-line short circuit is less than the three phase short circuit current. The thermal stresses and the mechanical stresses in the windings of a Y-/spl Delta/ transformer in the case of a line-to-line short circuit are as high as the stresses in the case of a symmetrical three phase short circuit. The current distribution in the windings of a Y-/spl Delta/ transformer is calculated. It is assumed that the sum of the ampere-turns of the windings on each leg of the core is zero. The line-to-line short circuit current distribution is then calculated explicitly. A general case for the calculation of voltage and current distributions in transformer windings of any connection is then discussed.
Organizational and Management Problems Confronting Redesigning Teaching and Learning in Nigerian Schools in the Globalization Era

This study identifies the hitherto 6-5-4 educational system in relation to its sustainability vis-a-vis the recent 6-3-3-4 educational system. However, the old design of 6-5-4 and 6-3-3-4 systems have outlived their importance since the two have failed in sustaining expected socio-economic developments. Hence, the introduction of UBE and 9-3-4 education system. Subsequently, the gap created by the old designs of educational system 6-5-4 and 6-3-3-4 call for an improvement in the old design for a redesigning, reformation and re-arrangement in modes, roles, policy and planning. It is against this backdrop that this paper advocates effective and efficient redesigning and optimal implementation of the redesigned roles and objectives. The paper concludes on a note that no design of education was bad but the success or failure of any system depends solely on the implementation.
Variables Involved in the Discordance between HbA1c and Fructosamine: The Glycation Gap Revisited

Aims Glycation gap (GG) is defined as the difference between the measured level of HbA1c and the level that would be predicted from its regression on the fructosamine level. The aims of the study were: 1) To determine the reproducibility and consistency of GC; 2) To discover factors related to GG value. Given that metformin might increase glucose transport through the erythrocyte membrane, this treatment was also considered in the analyses of the results. Methods GG was calculated in two blood samples separated 30.6 (SD 7.3) weeks, obtained in 508 type 2 diabetic patients. The following variables were considered: HbA1c, fructosamine, glucose, creatinine, hematological parameters and treatment with metformin. Multivariate and logistic regression analyses were performed to explore the variables independently related to CG. Results GG was reproducible and consistent over time. Creatinine, mean corpuscular hemoglobin concentration (MCHC), and glycemia (inverse relationship); and HbA1c and treatment with metformin (direct relationship) were independently related to GG. Patients treated with metformin showed higher HbA1c values, despite similar fructosamine concentrations, than patients not treated with the drug. Conclusions GG is independently related to serum levels of creatinine, MCHC and treatment with metformin. The spurious effect of metformin on Hb glycation could have serious clinical implications and should be considered when interpreting the results of clinical trials.
Rethinking the design of the Internet

This article looks at the Internet and the changing set of requirements for the Internet as it becomes more commercial, more oriented toward the consumer, and used for a wider set of purposes. We discuss a set of principles that have guided the design of the Internet, called the end-to-end arguments, and we conclude that there is a risk that the range of new requirements now emerging could have the consequence of compromising the Internet's original design principles. Were this to happen, the Internet might lose some of its key features, in particular its ability to support new and unanticipated applications. We link this possible outcome to a number of trends: the rise of new stakeholders in the Internet, in particular Internet service providers; new government interests; the changing motivations of a growing user base; and the tension between the demand for trustworthy overall operation and the inability to trust the behavior of individual users.
Intelligent Information Integration: Reclaiming the Intelligence

The authors present their work in the conceptualization, design, implementation, and application of â€œleanâ€ information integration systems. They present a new data integration approach based on a schema-less data management and integration paradigm, which enables developing cost-effective large scale integration applications. They have designed and developed a highly scalable, information-on-demand system called NETMARK, which facilitates information access and integration based on a theory of articulation management and a context sensitive paradigm. NETMARK has been widely deployed for managing, storing, and searching unstructured or semi-structured arbitrary XML and HTML information at the National Aeronautics Space Administration (NASA). In this paper the authors describe the theory, design and implementation of our system, present experimental benchmark evaluations, and validate our approach through real-world applications in the NASA enterprise.
Environmental Sustainability

This article investigates the driving forces of the ecological footprint (EF) and its six subcomponents to examine similarities in sources using a cross-national data set of more than 100 countries. Expectations from environmental impact, world-systems, and world-polity perspectives are incorporated in a model examining the institutional-level attributes driving national-level imprints on the biophysical environment. Results suggest that the structural factors driving ecological footprints differ across the EF's subcomponents and are similar for only one of its pieces, carbon uptake. Specifying alternative sets of predictors from previous research for three EF subcomponents offers support for a model specifying a set of simultaneous equations or seemingly unrelated regression models. These underlying processes, though driven by different structural influences, are linked with one another for the cross-national sample of countries examined here.
VF-14 item specific responses in patients undergoing first eye cataract surgery: can the length of the VF-14 be reduced?

Aims: To report the item specific responses of the VF-14 in a population of patients undergoing cataract surgery in their first eye and to determine whether or not the VF-14 can be reduced without compromising its performance as an index of cataract related visual impairment. Methods: The item specific responses to the VF-14 were analysed before (771 patients) and 4 months after (552 patients) cataract surgery in one eye to determine if the VF-14 index can be reduced without compromising its performance. Patients studied were selected from a cross sectional longitudinal study of patients undergoing cataract surgery in 72 ophthalmologist's offices located in three metropolitan regions of the United States. Results: Pairwise correlations between items in the VF-14 were all less than 0.6, indicating that no items could be removed solely on the basis of redundancy. 10 items correlated moderately with change in trouble, and 11 correlated moderately with change in satisfaction (r >0.15) at 4 months after cataract extraction. Eleven items demonstrated an effect size >0.4 at 4 months. These 11 items were either important for detecting cataract related functional disability or for quantifying the extent to which cataract impaired function. Additionally, 11 items were needed to detect adequately individuals with functional impairment. Three items (recognising people, cooking, and reading large print) were less responsive to cataract extraction and were more strongly associated with ocular comorbidities. Conclusions: While previous reports indicate that the VF-14 can be significantly shortened, our analysis only justifies removing three items. While the resulting VF-11 has properties similar to the VF-14, the limited time savings do not justify altering this already validated instrument.
Role of domain I of neuronal Ca2+ channel alpha1 subunits in G protein modulation.

1. We studied the G protein inhibition of heteromultimeric neuronal Ca2+ channels by constructing a series of chimeric channels between the strongly modulated alpha1B subunit and the alpha1E(rbEII) subunit, which showed no modulation. 2. In parallel studies, alpha1 subunit constructs were co-expressed together with the accessory Ca2+ channel alpha2-delta and beta2a subunits in mammalian (COS-7) cells and Xenopus oocytes. G protein inhibition of expressed Ca2+ channel currents was induced by co-transfection of Gbeta1 and Ggamma2 subunits in COS-7 cells or activation of co-expressed dopamine (D2) receptors by quinpirole (100 nM) in oocytes. 3. The data indicate that transfer of the alpha1B region containing the N-terminal, domain I and the I-II loop (i.e. the alpha1B1-483 sequence), conferred G protein modulation on alpha1E(rbEII), both in terms of a slowing of activation kinetics and a reduction in current amplitude. 4. In contrast, the data are not consistent with the I-II loop and/or the C-terminal forming a unique site for G protein modulation.
The Politics of Electoral Reform in Israel

This article falls into three main sections. The first outlines the basic features of the Israeli electoral system established in 1949, with minor amendments in the allocation formula (in 1973) and the electoral threshold (in 1992). The second covers unsuccessful proposals to reform Knesset elections in the periods 1949-77, 1977-90, and 1990 to date. The last section explains the causes of the introduction in 1992 of direct elections for the prime minister, and evaluates their possible conse quences. Since its first Knesset (parliamentary) elections in 1949 Israel has employed an electoral system with a single nationwide district, a propor tional representation allocation formula, and a strict list ballot. The basic alternative considered by Israeli politicians was the employment of a mixed system. Although reform proposals have been raised since the establishment of the state of Israel, no major change of the system has taken place until the March 1992 reform of the Government Basic Law. Following Israel's only successful vote on no-confidence, the Knesset adopted a governmental reform according to which the prime minister will be elected directly by voters. The directly elected prime minister must gain, however, the Knesset's confidence in his or her government. The present nature of the reform is such that a possible conflict between the prime minister and the Knesset may lead to a political and constitutional catastrophe.
