Identification of temporal factors related to shot performance for indoor recurve archery     

Andrew J. Callaway  Johanna Wiedlack  Mario Heller 《Journal of sports sciences》2017,35(12):1142-1147

The purpose of this study was to investigate the temporal phases of the archery shot cycle that distinguish the arrows distance from centre, in an attempt to understand critical factors that affect performance. Fifteen archers of varying ability each performed 30 shots at 18 m. Fourteen potential predictor variables were measured for statistical modelling by stepwise multiple linear regression. The results show that pre-shot time (pre-performance routine), follow-through time (post-performance routine), aiming time, speed of the arrow and the %variation in clicker-release time, account for 7.7% of the variation in predicting shot performance. The results have implications for practice demonstrating factors that coaches should focus on to develop their athletes. Further work on pre-, but more importantly, post-performance routines are needed generally within sport research as they are lacking and have been shown to be important contributing factors in a number of sports.  相似文献   

Dopingberichterstattung in den Medien     

Johanna Schirm  Henk Erik Meier 《Sportwissenschaft》2016,46(3):143-161

This contribution reviews existing research on media coverage of doping in Germany. Based on a keyword search, 22 works were identified. The review aims to provide a survey of the state of the art in terms of questions addressed, methods and results as well as blind spots and methodological deficits. Moreover, directions for future research are outlined. Although research is characterized by substantial methodological heterogeneity, central results can be presented following the influential approach of Bette and Schimank. In accordance with their ideas media coverage of doping is characterized by scandalization, personalization and moralization. However, shortfalls of theoretical perspective and methodological shortcomings are noted. These deficits serve as an inspiration for future research.  相似文献   

Degrees of value: comparing the contextual complexities of UK transnational education in Malaysia and Hong Kong     

I Lin Sin  Maggi W. H. Leung  Johanna L. Waters 《Compare》2019,49(1):132-148

This paper reveals the complex diversity that underpins ostensibly similar transnational education programmes (TNE), through a comparison of UK TNE in Malaysia and Hong Kong. It draws on data from two different yet cognate studies on the role of UK universities in delivering higher education in Asia. Some fine-grained and informative differences between the ways in which ‘value’ in TNE is constructed in different host contexts is revealed. The paper brings to light the ‘voices’ of TNE students and graduates, which are very seldom heard. The arguments adapt and extend the concepts of education as a positional good, and as cultural capital. For various instrumental, intrinsic and personal reasons the authors discuss in detail, UK TNE is more highly valued in Malaysia than in Hong Kong. The paper makes a wider contribution to knowledge on the changing landscape of international higher education and the impact on social and personal (dis)advantage.  相似文献   

Enhancing quality with a research-based student feedback instrument: a comparison of veterinary students’ learning experiences in two culturally different European universities     

Mirja Ruohoniemi  Monica Forni  Johanna Mikkonen  Anna Parpala 《Quality in Higher Education》2017,23(3):249-263

This paper explores the value of a research-based student inventory from the quality assurance point of view in two culturally different European higher education institutions for veterinary education. Perceived heavy workload is a well-known problem in veterinary studies and is a challenge to the quality of learning. First- and third-year students in both institutions responded to an inventory consisting of items regarding their approaches to learning, self-efficacy, study workload and the teaching-learning environment. There were differences in students’ approaches to learning and perceived workload between the two institutions. In both contexts, the strongest predictor of the workload turned out to be the surface approach to learning. Self-efficacy showed a positive correlation with the deep approach to learning and organised studying. The strengths of the teaching-learning environment varied between the institutions. Moreover, the present study discusses how the gained information could be used in improving the teaching-learning environment and students’ learning.  相似文献   

Tracing unique trajectories of participation for a ‘girl with ADHD’: from ‘unwilling student’ to ‘agentive learner’     

Ann-Carita Evaldsson  Johanna Svahn 《Emotional and Behavioural Difficulties》2019,24(3):254-272

ABSTRACT

The overall aim of this study is to explore how individual children with long-term school difficulties follow unique ‘trajectories of participation’ in special educational needs settings, sometimes in unexpected ways, and how this contributes to alternative forms of identification and processes of learning. The data draws on long-term video-ethnographic work, tracing trajectories of participation during the course of a school year for an individual girl with an ADHD diagnosis who is a newcomer to a special support school in Sweden. We use a multi-layered theoretical and methodological framework to learning, identities and participation as situated practices to explore how the focal girl, through her everyday participation in classroom contexts structured to amplify the student’s capabilities, gradually moves from an ‘unwilling student’ to an ‘agentive learner’. Through a multimodal interactional analysis, we demonstrate how the focal girl’s actions and the teacher’s scaffolding responses are interactionally organised, and the emotional and relational dimensions in the creation of participation frameworks for learning. It is argued that the student’s agency and emerging emotional engagement in school-based learning are intimately linked to the pursuit of building long-term learning relationships based on mutual trust.  相似文献   

Advances in urinary protein biomarkers for urogenital and non-urogenital pathologies     

Johanna Pedroza-Díaz  Sarah R?thlisberger 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2015,25(1):22-35

The discovery of protein biomarkers that reflect the biological state of the body is of vital importance to disease management. Urine is an ideal source of biomarkers that provides a non-invasive approach to diagnosis, prognosis and prediction of diseases. Consequently, the study of the human urinary proteome has increased dramatically over the last 10 years, with many studies being published. This review focuses on urinary protein biomarkers that have shown potential, in initial studies, for diseases affecting the urogenital tract, specifically chronic kidney disease and prostate cancer, as well as other non-urogenital pathologies such as breast cancer, diabetes, atherosclerosis and osteoarthritis. PubMed was searched for peer-reviewed literature on the subject, published in the last 10 years. The keywords used were “urine, biomarker, protein, and/or prostate cancer/breast cancer/chronic kidney disease/diabetes/atherosclerosis/osteoarthritis”. Original studies on the subject, as well as a small number of reviews, were analysed including the strengths and weaknesses, and we summarized the performance of biomarkers that demonstrated potential. One of the biggest challenges found is that biomarkers are often shared by several pathologies so are not specific to one disease. Therefore, the trend is shifting towards implementing a panel of biomarkers, which may increase specificity. Although there have been many advances in urinary proteomics, these have not resulted in similar advancements in clinical practice due to high costs and the lack of large data sets. In order to translate these potential biomarkers to clinical practice, vigorous validation is needed, with input from industry or large collaborative studies.Key words: urine, protein, biomarker  相似文献   

Impact of age on haematological markers pre- and post-marathon running     

Thomas G. Martin  Rachel W. Pata  Johanna D’Addario  Lauren Yuknis  Rebecca Kingston  Richard Feinn 《Journal of sports sciences》2015,33(19):1988-1997

This study investigated whether haematological markers differ between young and masters marathon participants, running at similar performance levels. Nine young (31.89 ± 4.96 years) and eight masters (63.13 ± 4.61 years) runners participated. At five time points (pre-race through 54 h post-race), a complete blood cell count, basic metabolic panel and creatine kinase (CK) isoenzyme panel were assessed. Race performance was standardised using the World Masters Association Age Grading Performance Tables. Total CK levels were elevated for all participants at all time points post-race (P < 0.001). The CK-isoenzyme MB% was elevated across groups at 6, 30 and 54 h post-race (P < 0.01, P < 0.01 and P < 0.05), with masters runners having a higher CK-MB% at 30 and 54 h (P < 0.05, P < 0.05). Total white blood cell and neutrophil counts were elevated through 6 h post-race (P < 0.001), with higher levels found in younger runners (P < 0.001). When considering all blood work, masters runners had a higher number of abnormal values at 6, 30 and 54 h post-race (P < 0.05, P < 0.01 and P < 0.05). In conclusion, masters runners demonstrated sustained CK-MB elevation, which may suggest greater cardiac stress. However, future studies using additional cardiac markers should be completed to confirm these findings. In addition, masters runners showed an increased number of laboratory values outside normal range, indicating the body’s reduced capacity to respond to marathon running.  相似文献   

Library as a Partner in Co-Designing Learning Spaces: A Case Study at Tampere University of Technology,Finland     

Johanna Tevaniemi  Jenni Poutanen  Riitta Lähdemäki 《New Review of Academic Librarianship》2015,21(3):304-324

This article presents a case of co-designed temporary learning spaces at a Finnish academic library, together with the results of a user-survey. The experimental development of the multifunctional spaces offered an opportunity for the library to collaborate with its parent organisation thus broadening the role of the library. Hence, library can be seen as a third player facilitating learning spaces. Additionally, the library's own expertise was strengthened through successful cooperation with the undergraduate students and other actors. The results support prior research, where studying in the library is target-oriented differing from other learning spaces in providing support and resources.  相似文献
