Unanticipated direction to cut after landing may alter the lower extremity landing biomechanics when performing landing motions. These alterations may potentially increase the risk of ACL injury. The purpose of this study was to determine if an unanticipated side-cut affects lower extremity landing biomechanics in females. Eighteen recreational female athletes participated in two blocks of testing: the first block of testing consisted of three acceptable trials of anticipated dominant limb and non-dominant limb 45-degree diagonal cutting after landing, which were performed in a counterbalanced order. The second block of testing consisted of three acceptable trials of unanticipated dominant limb and non-dominant limb diagonal cutting after landing. Data analysis mainly focused on the dominant limb landing biomechanics. Unanticipated side-cut landing, compared (paired t-test, p < 0.05) to the anticipated landings, resulted in less hip abduction and tibial internal rotation angle at initial contact (IC) and a lower maximum ankle inversion angle and a greater maximum knee abduction angle, and knee and hip displacement. Also, greater posterior GRF and a longer time to peak medial GRF were exhibited. These outcomes indicate that athletes may adapt their landing mechanics to land unsafely when encountering an unanticipated event.  相似文献   

Concurrent Validity of Actigraph-Determined Sedentary Time Against the Activpal Under Free-Living Conditions in a Sample of Bus Drivers

This study explored the validity of ActiGraph-determined sedentary time (<50 cpm, <100 cpm, <150 cpm, <200 cpm, <250 cpm) compared with the activPAL in a free-living sample of bus drivers. Twenty-eight participants were recruited between November 2013 and February 2014. Participants wore an activPAL3 and ActiGraph GT3X+ concurrently for 7 days and completed a daily diary. Time spent sedentary during waking hours on workdays, non-workdays, during working-hours, and non-working hours were compared between instruments. During working hours, all ActiGraph cut-points significantly underestimated sedentary time (p < 0.05), whereas during non-working hours the <50 cpm cut-point demonstrated the closest agreement (ActiGraph sedentary time: 250 ± 75 minutes versus activPAL sedentary time: 236 ± 65 minutes). Receiver operating characteristic analyses revealed that on workdays and non-workdays the ActiGraph cut-points exhibited relatively low sensitivity (all <0.62) and specificity (all <0.49) values. The use of the ActiGraph to measure sedentary time in this understudied, highly sedentary and at risk occupational group is not recommended.  相似文献   

Human resources for Big Data professions: A systematic classification of job roles and required skill sets     

Andrea De Mauro  Marco Greco  Michele Grimaldi  Paavo Ritala 《Information processing & management》2018,54(5):807-817

The rapid expansion of Big Data Analytics is forcing companies to rethink their Human Resource (HR) needs. However, at the same time, it is unclear which types of job roles and skills constitute this area. To this end, this study pursues to drive clarity across the heterogeneous nature of skills required in Big Data professions, by analyzing a large amount of real-world job posts published online. More precisely we: 1) identify four Big Data ‘job families’; 2) recognize nine homogeneous groups of Big Data skills (skill sets) that are being demanded by companies; 3) characterize each job family with the appropriate level of competence required within each Big Data skill set. We propose a novel, semi-automated, fully replicable, analytical methodology based on a combination of machine learning algorithms and expert judgement. Our analysis leverages a significant amount of online job posts, obtained through web scraping, to generate an intelligible classification of job roles and skill sets. The results can support business leaders and HR managers in establishing clear strategies for the acquisition and the development of the right skills needed to leverage Big Data at best. Moreover, the structured classification of job families and skill sets will help establish a common dictionary to be used by HR recruiters and education providers, so that supply and demand can more effectively meet in the job marketplace.  相似文献

Non-formal basic education as a development priority: Evidence from Nicaragua     

Sudhanshu Handa  Heiling Pineda  Yannete Esquivel  Blancadilia Lopez  Nidia Veronica Gurdian  Ferdinando Regalia 《Economics of Education Review》2009

Almost 900m adolescents and adults are illiterate in the developing world, yet most policy discussions focus on the educational circumstances of primary aged children. As a result non-formal educational programs for adolescents and adults are given very little support, and this group is virtually ignored in international agreements such as the millennium declaration. This article presents the first serious attempt at evaluating the impact of a non-formal education program. Results show significant learning achievement over the academic year, as well as strong development impacts of the program in non-learning dimensions of participants’ lives. These positive impacts, plus the significantly lower unit costs and self-targeted nature of the program provide strong evidence that this type of program can be an important part of the poverty reduction and human capital enhancement strategy of developing countries with large illiterate adult populations.  相似文献   

One year of anatomy teaching and learning in the outbreak: Has the Covid-19 pandemic marked the end of a century-old practice? A systematic review     

Veronica Papa  Elena Varotto  Massimo Galli  Mauro Vaccarezza  Francesco M. Galassi 《Anatomical sciences education》2022,15(2):261-280

At the end of 2019, the Covid-19 pandemic spread caused restrictions in business and social spheres. Higher education was also severely affected: universities and medical schools moved online to distance learning and laboratory facilities closed. Questions arise about the long-term effects of this pandemic on anatomical education. In this systematic review, the authors investigated whether or not anatomical educators were able to deliver anatomical knowledge during this pandemic. They also discuss the challenges that anatomical education has faced over the last year. The search strategy was conducted between July 2020 and July 2021. Two hundred and one records were identified, and a total of 79 studies were finally included. How best to deliver anatomy to students remains a moot point. In the last years, the advent of new technologies has raised the question of the possible overcoming of dissection as the main instrument in anatomical education. The Covid-19 pandemic further sharpened the debate. Remote learning enhanced the use of technologies other than cadaveric dissection to teach anatomy. Moreover, from the analyzed records it appears that both from students' perspective as well as teachers' there is a clear tear between those who endorse dissection and those who believe it could be easily overcome or at least integrated by virtual reality and online learning. The authors strongly believe that the best anatomy teaching practice requires the careful adaptation of resources and methods. Nevertheless, they support cadaveric dissection and hope that it will not be replaced entirely as a result of this pandemic.  相似文献   

Learning how to teach unfamiliar subjects: developing training on writing for publication and presentation of research for health libraries     

Eleanor Barker  Veronica Phillips 《Health information and libraries journal》2020,37(2):163-167

Academic librarians with teaching responsibility have traditionally delivered training in discovering and organising information. However, in recent years, there has been an increased emphasis on supporting researchers through all stages of the research lifecycle. While librarians are ideally placed to provide training in writing for publication and presentation of research, very few in the United Kingdom appear to be doing so. However, there are clear benefits to teaching these subjects. Based on feedback from faculty on user needs, the University of Cambridge Medical Library’s training programme was expanded to include training and support in the publication and presentation of research outputs. This article recounts the process by which the new courses were developed, and the techniques used by the library’s teaching staff to gain understanding of conventions and requirements of forms of written communication with which they were unfamiliar. It also evaluates the impact of the new courses, discusses next steps and provides advice for other librarians wishing to develop similar courses. D.I.  相似文献   

Collective intelligence for advancing ocean literacy     

Veronica McCauley  Patricia McHugh  Kevin Davison  Christine Domegan 《Environmental Education Research》2019,25(2):280-291

Ocean literacy is an understanding of the ocean’s influence on us and our influence on the ocean. A lack of ocean literacy presents a significant obstacle for citizens to engage in environmentally sustainable behaviour, and thus is acknowledged as a ‘complex problem’ that requires deliberative participation and joint-action by stakeholders across domains. The aim of the article is both to demonstrate the value of Collective Intelligence (CI) as a methodological tool to advance and enhance the promotion of environmental literacy, and to share outcomes from using the CI approach. The participatory context behind CI illustrates that working ‘with’ a range of stakeholders across marine education, outreach, regulation and policy, to debate how to better promote ocean literacy among young people, improves ocean literacy and broadens society’s awareness of sustainable marine environments. Findings reveal a hierarchical barrier structure localised to each country, a valuable order of echelon toward environmental change.  相似文献   

Encouraging Better Graphic Design in Libraries: a Creative Commons Crowdsourcing Approach     

Veronica Arellano Douglas  April Aultman Becker 《图书馆管理杂志》2015,55(6):459-472

A dearth of published literature about graphic design in libraries reveals that little attention has been focused on librarians' visual communication abilities and the impact of print and Web publications on users' interaction with library services and collections. This case study examines one approach to improving the quality of graphic design in libraries. Through a combination of social media and accessible cloud-based storage, Librarian Design Share, a crowdsourced archive of library-related visual materials, highlights exemplars of visual communication in libraries and makes designs freely available for adaptation under a creative commons license.  相似文献   

Phonological skill,lexical decision and letter report performance in good and poor adult spellers     

Jackie Masterson  Veronica Laxon  Sophie Lovejoy  Victoria Morris 《Journal of Research in Reading》2007,30(4):429-442

Two groups of undergraduate students, matched for reading skill but differing in spelling ability, participated in three experiments with the aim of exploring the causes of differences in spelling skill in this population. In the first experiment participants were presented with a range of tasks to investigate the possibility that the poor spellers had poorer phonological abilities than the good spellers. No significant differences were observed. In Experiment 2, a lexical decision task was used. The words in the task differed in orthographic neighbourhood size (N) and frequency. Analysis of the latencies revealed effects of frequency and N, but the effect of spelling group was not significant and neither was the interaction with N. Analysis of the errors revealed that the poor spellers made significantly more errors than the good spellers. In Experiment 3 participants were asked to identify the letters in briefly presented words and non‐words. There was a significant effect of stimulus type in favour of words. Poor spellers made more errors in the task than the good spellers, although the difference was restricted to non‐words. Finally, an analysis of the errors made in spelling to dictation by the two groups was carried out. This revealed that the poor spellers were more likely than the good spellers to make errors that were not phonologically plausible and that differed markedly from the target. Overall, the results are interpreted in terms of a partial orthographic representations explanation of poor spelling in good readers.  相似文献
