Technology Acceptance in Social Work Education: Implications for the Field Practicum     

Alex Don Colvin  Angela N. Bullock 《Journal of Teaching in Social Work》2013,33(5):496-513

The exponential growth and sophistication of new information and computer technology (ICT) have greatly influenced human interactions and provided new metaphors for understanding the world. The acceptance and integration of ICT into social work field education are examined here using the technological acceptance model. This article also explores potential challenges regarding the adoption of ICT into social work field practica. The article concludes with implications for adopting and integrating ICTs in social work field education.  相似文献   

Regulatory policy as innovation: Constructing rules of engagement for a technological zone of tissue engineering in the European Union   总被引：2，自引：0，他引：2  

Alex Faulkner 《Research Policy》2009,38(4):637-646

This paper addresses the question of the part that regulation plays in processes of innovation in sectors of technology. The politico-economic phenomenon of ‘Europe’ is partly constituted by regulatory regime-building, and new technologies are one of the major sites of regime-building. A constructionist social theory perspective shows that study of the conflictual processes of regulatory policymaking affords insights into the formation of the rules of engagement that constitute technology domains. Adopting the concept of emergent ‘technological zone’ in preference to industrial ‘sector’ or technoscientific network, the paper presents, using empirical research, a detailed account of the case of the debate and development of regulatory policy for therapeutic tissue engineering in the European Union's policy institutions and stakeholder networks. It describes how the jurisdiction of an emergent zone has been formed through such negotiations, providing a counter-example to the common view that regulation ‘lags behind’ innovation. The analysis takes account particularly of the part played by the malleability of the definition of the material technology itself in such constructive governance processes, and it also suggests various consequences for the array of producers of the technology, for market structuring and for the innovation pathways taken by tissue engineering technology. Concluding, the paper argues that there is conceptual advance to be made by bringing together constructionist social theory with innovation studies approaches that highlight the part played by non-firm, public institutions in shaping innovation ecologies.  相似文献   

Relationship between an editor in chief's commentary publications and the impact factor of cardiovascular medicine journals     

Alex Salazar  Michael Joseph Berry 《Journal of the Medical Library Association》2021,109(3):459

Journal impact factor (IF) inflation is suggested as a problem resulting from commentaries published by the editors in chief (EiCs) of their respective journals. However, it is unclear whether this is a systemic problem across the top thirty cardiovascular medicine journals. Therefore, the purpose of this investigation was to examine the relationship between the number of commentaries written by an EiC and their journal''s IF and Eigenfactor (Ef). Utilizing Spearman rank partial correlations controlling for length of service as the EiC, significant moderate correlations were found between the number of commentaries and the number of first-author commentaries by the EiC and the IF of their journal (r=0.568, p=0.001 and r=0.504, p=0.005; respectively). A weak but still significant correlation was found between the number of commentaries by the EiC and the Ef of their journal (r=0.431, p=0.020). The reason for these correlations is unclear, and whether the methodology used to compute the IF and Ef should be modified needs further research.  相似文献

Social Loafing in a Co-operative Classroom Task     

Adrian C. North  P. Alex Linley  David J. Hargreaves 《教育心理学》2000,20(4):389-392

Social loafing refers to the tendency for individuals to reduce their own personal input when performing as part of group. This phenomenon may be problematic if it exists in educational contexts, given a current emphasis on group collaborative classroom activities. The present study investigated whether social loafing existed in a collaborative educational task, employing groups of three and eight participants. The results indicated that individuals working within the smaller groups were more productive than those working in larger groups, consistent with the social loafing hypothesis. Future research should determine whether the detrimental effects on students' collaborative performance attributable to social loafing are justifiable in terms of gains accrued in other (e.g. interpersonal) domains.  相似文献   

Changes in mechanical properties of sprinting during repeated sprint in elite rugby sevens athletes     

Pedro Jiménez-Reyes  Matt Cross  Alex Ross  Pierre Samozino  Matt Brughelli  Nicholas Gill 《European Journal of Sport Science》2019,19(5):585-594

This study aimed to analyse fatigue-induced changes in mechanical sprinting properties during a specific repeated-sprint test in elite rugby sevens athletes. Twenty elite rugby sevens players performed ten 40?m sprints on a 30?s cycle with participant’s running back and forth in a marked lane. Radar was used to assess maximal overground sprint performance over each 40?m. Macroscopic mechanical properties (maximal horizontal force (F₀), maximal horizontal power (P_max), maximal ratio of horizontal force (RF_peak), decrease in the ratio of horizontal-to-total force (D_RF), total force and maximal sprinting velocity (v₀)) were drawn from horizontal force velocity relationships, using a validated method applied to the speed–time data. Fatigue-induced changes were analysed comparing the first sprint to an average of 2^nd-4^th, 5^th-7^th and 8^th-10^th. Repeated-sprint ability (RSA) testing induced substantial changes in the maximal velocity component, with a decrease (–15%) in v₀ (effect size (ES)?=?–2.46 to –4.98), and to a lower extent (–5.9%) in the maximal force component F₀ (ES?=?–0.59). D_RF moderately decreased (14%; ES=–0.76–1.11), and RF_peak largely decreased in the later sprints (ES?=?–0.32 to –1.27). Fatigue observed in this RSA test appeared to have a greater effect on the technical ability to produce horizontal force at high velocities, likely due to an alteration in the ability to maintain horizontally oriented force application when velocity increases rather than during the initial acceleration phase, but also the overall force production capacity. The ability to maintain forward-oriented force at high velocities is of central importance for identifying fatigue and monitoring load.  相似文献

Neural information retrieval: at the end of the early years

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research.  相似文献
