ABSTRACT

The effectiveness of 8-week force-velocity optimised training was assessed in highly trained professional rugby league athletes. Players (age 24 ± 3 years; body mass 94.9 ± 21.6 kg; height 181.3 ± 6.0 cm) were strength-matched and assigned to a force-velocity optimised group (OP; n = 15) or a general strength-power group (GP; n = 14). Tests included 10-m, 20-m sprints, 3 repetition-maximum squat and squat jumps over five load conditions to ascertain vertical force-velocity relationship. ANCOVA revealed there was a group effect for force-velocity deficit (P < 0.001), with the OP two-fold greater than the GP group (OP pre: 51.13 ± 31.42%, post: 62.26 ± 31.45%, GP pre: 33.00 ± 19.60%, post: 31.14 ± 31.45%, P < 0.001). There were further group effects for 3RM squat (OP pre: 151.17 ± 22.95 kg, post: 162.17 ± 24.16 kg, GP pre: 156.43 ± 25.07 kg, post: 163.39 ± 25.39 kg, P < 0.001), peak power (OP pre: 3195 ± 949 W, post: 3552 ± 1033 W, GP pre: 3468 ± 911 W, post: 3591 ± 936 W, P < 0.001), and SJ (OP pre: 39.79 ± 7.80 cm, post: 42.69 ± 7.83 cm, GP pre: 40.44 ± 6.23 cm, post: 41.14 ± 5.66 cm, P < 0.001). Prescribing F-V deficit training is superior for improving physical performance within highly trained RL players.  相似文献

Efficient distributed selective search     

Yubin Kim  Jamie Callan  J. Shane Culpepper  Alistair Moffat 《Information Retrieval》2017,20(3):221-252

Simulation and analysis have shown that selective search can reduce the cost of large-scale distributed information retrieval. By partitioning the collection into small topical shards, and then using a resource ranking algorithm to choose a subset of shards to search for each query, fewer postings are evaluated. In this paper we extend the study of selective search into new areas using a fine-grained simulation, examining the difference in efficiency when term-based and sample-based resource selection algorithms are used; measuring the effect of two policies for assigning index shards to machines; and exploring the benefits of index-spreading and mirroring as the number of deployed machines is varied. Results obtained for two large datasets and four large query logs confirm that selective search is significantly more efficient than conventional distributed search architectures and can handle higher query rates. Furthermore, we demonstrate that selective search can be tuned to avoid bottlenecks, and thus maximize usage of the underlying computer hardware.  相似文献   

The role of a local newspaper after disaster: an intrinsic case study of Ishinomaki,Japan     

Jamie Matthews 《亚洲交流杂志》2017,27(5):464-479

The city of Ishinomaki in Miyagi prefecture was devastated by the tsunami that struck Japan’s North East Coast on 11 March 2011. Drawing on fieldwork conducted in Ishinomaki, which included interviews with senior journalists from the city’s two local newspapers, the Ishinomaki Hibi Shimbun and the Ishinomaki Kahoku, this paper presents an intrinsic case study of the role a local newspaper in Ishinomaki after the Great East Japan Disaster. The evidence reveals that in the immediate aftermath of the tsunami journalists recognised how their newspaper could serve the immediate information-needs of the local community by providing essential lifeline information, describing a duty to report, despite the operational difficulties that their newspapers faced. In the longer term recovery phase, interviewees acknowledged how their newspapers have attempted to communicate a message of hope to the city and provide an alternative perspective to the national media, which sometimes gave a false impression of the state of Ishinomaki’s recovery. This paper offers some insights into journalistic role conceptions, illustrating how journalists from the two newspapers embraced the role of information-disseminator after the disaster, and also identifies avenues for further research.  相似文献

Children’s Developing Ability to Resolve Disagreements by Integrating Perspectives     

Jamie Amemiya  Caren M. Walker  Gail D. Heyman 《Child development》2021,92(6):e1228-e1241

Children live in a world where disagreement is commonplace. Although disagreement can sometimes be explained by differences in people’s reliability, disagreement may also indicate that the referent elicits multiple perspectives. The present studies (total N = 129, 5- to 12-year-old ethnically diverse U.S. children, 42% girls) examined children’s ability to resolve disagreement among two individuals by identifying referents that integrated the perspectives, and considered the extent to which any age-related change could be explained by epistemological understanding (i.e., acknowledging that two perspectives can be right). Children’s age was positively correlated with their ability to integrate perspectives, and children performed at above-chance levels by approximately 10 years of age. Age differences in integrating perspectives were partially accounted for by epistemological understanding.  相似文献   

Training engaged student employees: A small college library experience     

Jamie P. Kohler 《College & Undergraduate Libraries》2016,23(4):363-380

Student employees are often the first people patrons contact when they enter an academic library, and thus their knowledge level and service skills are crucial to academic library success. This article presents a case study of the job-related knowledge and customer service skills of undergraduate student employees in a small liberal arts college after the implementation of a training program more focused on patron service. Both successes and failures are discussed.  相似文献   

PowerPoint slide provision and student performance: the moderating roles of self-efficacy and gender     

Agnes Zdaniuk  Jamie A. Gruman  Scott A. Cassidy 《Journal of Further & Higher Education》2019,43(4):467-481

Research on the pedagogical value of providing students with PowerPoint (PPT) slide handouts has produced mixed results. One reason for the inconsistent findings may be that most studies in this stream of research have neglected to examine individual differences. In the current study, we aimed to advance research on the pedagogical value of providing students with access to PPT slide handouts by examining whether self-efficacy and gender influence the effect of PPT slide provision on academic performance. We found no evidence to suggest that the provision of slide handouts has broad, unconditional pedagogical value. Instead, we found that both self-efficacy and gender moderated the extent to which the availability of the handouts enhanced or hindered students’ performance. As predicted, both students high on self-efficacy and males performed significantly better when they were provided with handouts. Conversely, students low on self-efficacy performed significantly worse when the handouts were provided. Female students also trended toward lower performance when the handouts were provided. Additionally, we found that students who were provided with PPT handouts perceived their instructor as more effective, and that this relation was mediated by students’ feeling of preparation. Finally, students also considered the provision of PPT handouts more valuable to their learning and course performance than one-to-one interactions with the professor. Implications for research and practice are discussed.  相似文献
