Re-Envisioning E-Resource Holdings Management     

Marlene van Ballegooie 《期刊图书馆员》2016,70(1-4):135-148

For e-resource librarians, maintaining e-book and e-journal holdings within electronic resource management systems is a labor intensive and often manual process. In 2014, with the aim of saving library staff valuable time and effort, the Online Computer Library Center, Inc. (OCLC) launched a service to provide automated holdings management within the WorldCat knowledgebase. For a select group of content providers, including some of the largest e-book aggregators, holdings information can be populated and updated automatically within the knowledgebase without intervention from library staff. At the University of Toronto Libraries, we conducted a study to assess the accuracy and efficiency of these automated holdings management services. This presentation outlines the results of the study and provides suggestions for further improvement to the current services offered.  相似文献

Remote effects of lower limb stretching: preliminary evidence for myofascial connectivity?     

Jan Wilke  Daniel Niederer  Lutz Vogt  Winfried Banzer 《Journal of sports sciences》2016,34(22):2145-2148

The skeletal muscles and the fibrous connective tissue form an extensive, body-wide network of myofascial chains. As fascia can modify its stiffness, strain transmission along these meridians is supposable. The goal of this trial therefore was to collect pilot data for potential remote effects of lower limb stretching on cervical range of motion (ROM). Twenty-six healthy participants (30 ± 6 years) were included in the matched-pairs intervention study. One group (n = 13) performed three 30 s bouts of static stretching for the gastrocnemius and the hamstrings, respectively. An age- and sex-matched control group (CG; n = 13) remained inactive. Pre- and post-intervention, maximal cervical ROM in flexion/extension was assessed. A repeated measures ANOVA revealed systematic differences between groups (P < .05). ROM increased following stretching (143.3 ± 13.9 to 148.2 ± 14°; P < .05) but remained unchanged in the CG (144.6 ± 16.8 to 143.3 ± 16.8°; P > .05). Our data point towards existence of a strain transfer along myofascial meridians. Further randomised controlled studies on conditions, factors and magnitude of tensile transmission are warranted.  相似文献   

The key to success in elite athletes? Explicit and implicit motor learning in youth elite and non-elite soccer players     

L. Verburgh  E. J. A. Scherder  P. A. M. van Lange  J. Oosterlaan 《Journal of sports sciences》2016,34(18):1782-1790

In sports, fast and accurate execution of movements is required. It has been shown that implicitly learned movements might be less vulnerable than explicitly learned movements to stressful and fast changing circumstances that exist at the elite sports level. The present study provides insight in explicit and implicit motor learning in youth soccer players with different expertise levels. Twenty-seven youth elite soccer players and 25 non-elite soccer players (aged 10–12) performed a serial reaction time task (SRTT). In the SRTT, one of the sequences must be learned explicitly, the other was implicitly learned. No main effect of group was found for implicit and explicit learning on mean reaction time (MRT) and accuracy. However, for MRT, an interaction was found between learning condition, learning phase and group. Analyses showed no group effects for the explicit learning condition, but youth elite soccer players showed better learning in the implicit learning condition. In particular, during implicit motor learning youth elite soccer showed faster MRTs in the early learning phase and earlier reached asymptote performance in terms of MRT. Present findings may be important for sports because children with superior implicit learning abilities in early learning phases may be able to learn more (durable) motor skills in a shorter time period as compared to other children.  相似文献   

Socialisation into organised sports of young adolescents with a lower socio-economic status     

Niek Pot  Jan Verbeek  Joris van der Zwan  Ivo van Hilvoorde 《Sport, Education and Society》2016,21(3):319-338

Studies investigating sport socialisation often focussed on the barriers for youngsters from lower socio-economic status (SES) families to participate in sport. In the present study, the socialisation into sports of young adolescents from lower SES families that do participate in organised sports was investigated. A total of 9 girls and 12 boys from lower SES families (18 Dutch; three foreign ethnic background) from one city in the Netherlands who participated in organised sport were interviewed. Although multiple agents may be of influence on the socialisation process, this study was limited to the family, school and peers as potential socialising contexts. Drawing on the theoretical work of Bourdieu and Bernstein, parents were found to be the main influencers of the sports habitus of these young adolescents. The school context appeared to have no influence on their sport socialisation. Peers were found to have an influence on the choice for a specific type of sport. This interplay between socialising contexts for young adolescents from lower SES families is similar to the sport socialisation of youngsters from higher SES families. Therefore, it is suggested that if sport socialisation takes place, then the role of SES is less pronounced than often assumed. Moreover, there seem to be differences in the relative importance of the socialising contexts with younger children with a lower SES. Therefore, it is hypothesised that the relative importance of socialising agents changes over time. Although the findings may be limited to the specific sample of this study, they provide hypotheses that challenge the often-presumed importance of SES if sport socialisation takes place.  相似文献   

Active recovery of the finger flexors enhances intermittent handgrip performance in rock climbers     

Jiří Baláš  David Giles  Jan Kodejška  Michaela Panáčková  Simon Fryer 《European Journal of Sport Science》2016,16(7):764-772

This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P?P?P?相似文献   

What’s in a name: dimensions of social learning in teacher groups     

E. Vrieling  A. van den Beemt  M. de Laat 《Teachers and Teaching》2016,22(3):273-292

Induced by a literature review, this paper presents a framework of dimensions and indicators highlighting the underpinning aspects and values of social learning within teacher groups. Notions of social networks, communities of practice and learning teams were taken as the main perspectives to influence this social learning framework. The review exercise resulted in four dimensions: (1) practice, (2) domain and value creation, (3) collective identity and (4) organization. The indicators corresponding to these dimensions serve as the foundation for understanding social learning in practice. The framework of dimensions and indicators can be of assistance for researchers as well as teacher groups that aim to assess their views on social learning and analyse whether these views fit the learning goals of the group or that adjustments are required. In this way, learning processes within groups of teachers can be improved.  相似文献   

Organising and leading systematic quality work in the preschool – preschool managers’ perspectives     

Jan Håkansson 《School Leadership & Management》2016,36(3):292-310

Preschool managers’ responsibility for and leadership of systematic quality work has come to the fore in connection with changes made to the Swedish preschool curriculum. The aim of this study is to contribute to the understanding of preschool managers’ leadership and management of the systematic quality work in Swedish preschools with reference to three specific domains: (i) governance, leadership/management and organisation, (ii) content and methods and (iii) development work and collegiate learning. Using qualitative methods, 18 preschool managers’ perspectives of leading systematic quality work have been analysed in relation to previous research. The results show a tension between linear and interactive forms of governance in the systematic quality work, but also that knowledge gaps among the staff can lead to uncertainties that the preschool manager has to address. At the same time, the results show the diversity of and variation in how children’s development and increased proficiency are documented, while the documentation of the quality of the work focuses on learning environments rather than on teaching and teacher competence. In the study, there are traces of what can be characterised as leadership for learning. This needs to be investigated more closely using other methods in future research.  相似文献   

The clinical use of motivational messages: an inquiry into the validity of the ARCS model of motivational design   总被引：2，自引：0，他引：2  

Jan Visser  John M. Keller 《Instructional Science》1990,19(6):467-500

Instruction, even when prepared according to sound instructional design principles, often does not stimulate students' motivation to learn. A motivational intervention, developed according to the processes outlined inthe ARCS model of motivational design, was implemented and tested following the conventions of an embedded single-case study. It was tested with a group of 15 adults participating in a staff development course conducted within the Mozambique Ministry of Education. Results, based on concurrent and discriminant analysis of both quantitative and qualitative data, indicated that the primary treatment, motivational messages, had positive effects on student attitude and performance. It may be concluded that the specific intervention and the ARCS model which provided the basis for designing it provide a sound basis for positively influencing student motivation to learn.  相似文献   

Modular programming of curricula     

P. J. van Eijl 《Higher Education》1986,15(5):449-457

A large scale modularisation of curricula in higher education based on relatively large modules is discussed. These modules are flexible courses and not the well known small instructional modules within a course. The idea of these so-called programme modules, together with some applications and implications are discussed in the context of the Dutch higher educational system which is quite similar to that in other Western European countries. One implication is a less static concept of what a curriculum is. This may affect students, teachers, curriculum planners and legislators in their thinking about what kind of education a university can offer (in the near future) to its potential clients.  相似文献
