This study examined a structural model of mathematics achievement among Druze 8th graders in Israel. The model integrates 2 psychosocial theories: goal theory and social learning theory. Variables in the model included gender, father's and mother's education, classroom mastery and performance goal orientation, mathematics self-efficacy and self-regulated learning, mastery and performance goals, and mathematics achievement. Data on learner and learning environment variables and achievement in mathematics were collected from 273 boys and girls. Results indicate appropriate fit of the model for the entire sample. Invariance analysis across gender indicated that only 2 of the 11 path coefficients, mother's education on mathematics achievement and classroom mastery goal orientation on self-regulation, were not invariant across gender. The same pattern of relationships accounted for different amounts of variance in mathematics achievement for boys and girls. 相似文献

eCommerce, Brexit, new safety and security concerns are only a few examples of the challenges that government organisations, in particular customs administrations, face today when controlling goods crossing borders. To deal with the enormous volumes of trade customs administrations rely more and more on information technology (IT) and risk assessment, and are starting to explore the possibilities that data analytics (DA) can offer to support their supervision tasks. Driven by customs as our empirical domain, we explore the use of DA to support the supervision role of government. Although data analytics is considered to be a technological breakthrough, there is so far only a limited understanding of how governments can translate this potential into actual value and what are barriers and trade-offs that need to be overcome to lead to value realisation. The main question that we explore in this paper is: How to identify the value of DA in a government supervision context, and what are barriers and trade-offs to be considered and overcome in order to realise this value? Building on leading models from the information system (IS) literature, and by using case studies from the customs domain, we developed the Value of Data Analytics in Government Supervision (VDAGS) framework. The framework can help managers and policy-makers to gain a better understanding of the benefits and trade-offs of using DA when developing DA strategies or when embarking on new DA projects. Future research can examine the applicability of the VDAGS framework in other domains of government supervision. 相似文献

Sex differences favoring males in spatial abilities have been known by cognitive psychologists for more than half a century. Spatial abilities have been related to three‐dimensional anatomy knowledge and the performance in technical skills. The issue of sex differences in spatial abilities has not been addressed formally in the medical field. The objective of this study was to test an a priori hypothesis of sex differences in spatial abilities in a group of medical graduates entering their residency programs over a five‐year period. A cohort of 214 medical graduates entering their specialist residency training programs was enrolled in a prospective study. Spatial abilities were measured with a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRTA) and three (MRTC) dimensions. Sex differences favoring males were identified in 131 (61.2%) female and 83 (38.8%) male medical graduates with the median (Q1, Q3) MRTA score [12 (8, 14) vs. 15 (12, 18), respectively; P < 0.0001] and MRTC score [7 (5, 9) vs. 9 (7, 12), respectively; P < 0.0001]. Sex differences in spatial abilities favoring males were demonstrated in the field of medical education, in a group of medical graduates entering their residency programs in a five‐year experiment. Caution should be exerted in applying our group finding to individuals because a particular female may have higher spatial abilities and a particular male may have lower spatial abilities.

ABSTRACTThe articles included in this special issue of Quest emerged from a research workshop entitled Thinking About Our Thinking in Adapted Physical Activity, held at the University of Alberta in Edmonton, Canada, from June 18–19, 2013. The aim of the workshop was to examine different worldviews that contribute to the adapted physical activity research literature, to identify key disciplinary assumptions, and to outline their consequences for multidisciplinary and interdisciplinary research in the field. A lack of understanding of the basic assumptions held by researchers often impedes communication between the disciplines. Hence, a sub-theme of this special issue is communication across disciplines. These conversations are, of course, essential to interdisciplinary inquiry. 相似文献

Information and communications technologies (ICT) are becoming pervasive in the residential real-estate industry and their usage is affecting the work lives of real-estate agents. Drawing on data from a regional study of the residential real-estate industry in the United States, we focus on the disintermediation or, more accurately, the reintermediation of real-estate agents in the sales process. Using data collected from interviews, direct observation, and archival records, we examine how real-estate agents are (1) taking advantage of new ICT in their work, and (2) protecting themselves from others wishing to displace their position in the real-estate value chain. Our analysis of this activity draws on two contrasting theoretical perspectives to illuminate the roles of residential real-estate agents: transaction cost and social capital. The results of this study provide insights into the ways in which ICT are used to build and draw on the social relationships that underpin the actual transactions, to help guide the process of buying/selling a house, and to invoke expertise as needed. 相似文献

Interdisciplinarity plays a major role in the debate about the sustainability of human societies, in general, and about the crisis and the future of the University. If the twentieth century can be identified as an era of specialization in Academia, there is a tendency now to add interdisciplinary spaces to the traditional disciplinary research and training organization. Non-academic research institutions (NARIs) are showing more flexibility than universities to respond to problem-oriented demands. This article analyzes the current prevalence of a rigid disciplinary academic framework and discusses its limitations in the face of complex demands, such as sustainability science (SS) and technology. Examples from the Brazilian graduate programs in SS are presented to describe some institutional pathologies that usually affect the attempts to achieve interdisciplinarity and SS and technology. Among the main conclusions, are the need for more interaction among universities and NARIs and the need to integrate disciplinarity and interdisciplinarity, rather than continue to deal with them as opposites. 相似文献

ABSTRACT This study investigated the effects of maturity status on knee extensor torque and vastus lateralis architecture of young soccer players. Thirty-four males aged 13–18 years were divided into two groups: pubescent (PUB, n = 15) and postpubescent (POSP, n = 19). Torque by angle interaction was established for absolute [F(2.649, 84.771) = 9.066, p < 0.05] and relative to body mass [F(2.704, 86.533) = 4.050, p < 0.05] isometric torque with the POSP group showing greater values. Muscle volume torque-angle relationship was similar between groups. Absolute, relative to body mass, and relative to muscle volume concentric and eccentric torque-velocity relationship showed a non-significant interaction but a significant group effect in favour the POSP group for absolute and concentric torque relative to body mass. Torque-angle and torque-velocity relationship normalized by body mass allometric exponents showed a non-significant interactions and group effects. Muscle thickness (3.6 ± 0.6 vs. 3.8 ± 0.6 cm), fascicle length (8.3 ± 1.4 vs. 8.9 ± 1.6 cm) and pennation angle (15.0 ± 2.3 vs. 14.3 ± 3.2 degrees) was similar between PUB and POSP groups, respectively. Maturity status did not show a significant effect on muscle architecture and on isometric and dynamic torques when allometrically normalized. 相似文献

ABSTRACTAmid ongoing disruption, discourse about journalism increasingly emphasizes innovation within the newsroom and the rise of entrepreneurial initiatives outside it. This article uses the concept of interpretive repertoires to explore how students enrolled in journalism programmes in Britain and the Netherlands understand innovation and entrepreneurialism in relation to changing industry circumstances and long-standing conceptualizations of occupational norms and behaviours. We find shared repertoires that embrace technological change, but generally within an acceptance of traditional normative practice. 相似文献
