Hardness measurement of natural and hybrid turf soccer fields     

Selina Yasemin Thanheiser  Sven Grashey-Jansen  Georg Armbruster 《Sports Engineering》2018,21(4):367-377

Understanding the surface hardness of soccer fields is essential to evaluate the risk of injury and also its influence on the playing behavior of soccer players. In this context, newly developed hybrid turf systems have to be tested for their surface hardness with regard to the increased risk of injury on hard sports surfaces. The hardness of a soccer field can be quantitatively measured using an apparatus with a cylindrical weight that is dropped from a defined height. Since this procedure was first used for road construction, there are few studies investigating its use on sports grounds. This has led to inconsistencies in methodology and the absence of evaluation guidelines for classifying the hardness of soccer fields. This paper considers how turf systems (natural turf and hybrid turf) differ in their hardness and how this method can be used for different soccer turf systems. Natural turf systems, stitched turf systems, hybrid turf-bearing layer systems and woven mat systems were investigated. The assessment results from a comparative representation of hardness values of different soccer fields. By comparison, natural turf systems were found to be the softest, while woven mat systems were the hardest. Furthermore, the parameters that might affect the hardness were investigated. The influence of the measured soil parameters decreases with an increasing number of measurements per measuring point. Turf system-specific correlations make it possible to reduce the amount of measurement effort.  相似文献   

Tensions in stakeholder relations for a Swedish football club – a case study     

Sven Junghagen 《Soccer & Society》2018,19(4):612-629

Swedish football is an industry not yet being as commercial as the big leagues and is regulated in terms of ownership of clubs. This implies a need for management of stakeholder relations for a Swedish football club. This paper identifies important stakeholders in Swedish football and discusses the multitude of – sometimes conflicting – objectives in managing these relations. The empirical base of the study is founded in a case study of Malmö FF, one of the dominant clubs in Sweden, with a qualitative single case research approach. Data are collected by means of semi-structured interviews and participant observations. The results of the study show a number of tensions as paradoxes for stakeholder management, suggest management dispositions to reconcile these paradoxes and suggest areas for further research.  相似文献   

Children exposed to obscene phone calls: what they remember and tell     

Leander L  Granhag PA  Christianson SA 《Child abuse & neglect》2005,29(8):871-888

OBJECTIVE: This case study examined children's reports from an obscene phone call (i.e., a verbal sexual abuse). We investigated which type of information the children reported, the completeness and accuracy of the children's statements, and whether there were systematic patterns in terms of memory distortions and omissions. METHOD: The completeness and the accuracy of the children's statements were examined by matching 64 children's statements given during police interviews with a detailed documentation of each phone call, made by the perpetrator during the actual phone calls. RESULTS: All children remembered the phone call per se, but they were found to omit almost all of the sexual and sensitive information (perpetrator's questions and statements) and about 70% of the neutral information given by the perpetrator. However, the children were accurate in the information they did report. CONCLUSIONS: The fact that the children did remember more of the neutral information suggests that they actually remembered the sexual information as well, but that they chose not to report it. Results indicate that children who have been sexually abused may remember more than they report in an initial interview. One possible underlying reason is that children experience shame or embarrassment.  相似文献

Asking for Help: A Relational Perspective on Help Seeking in the Workplace     

Janine van der Rijt  Piet Van den Bossche  Margje W. J. van de Wiel  Sven De Maeyer  Wim H. Gijselaers  Mien S. R. Segers 《Vocations and Learning》2013,6(2):259-279

In the context of the complexity of today’s organizations, help seeking behavior is considered as an important step to problem solving and learning in organizations. Yet, help seeking has received less attention in organizational literature. To increase the potential impact of help seeking on learning, it is essential to understand which mechanisms affect help seeking. The present study questioned whether the characteristics of the relationships that employees have in the workplace are related to help seeking behavior. This study draws on a social network perspective to investigate the employees’ relationships within their professional network. In particular, the role of accessibility, awareness of expertise, trust, and hierarchy in help seeking was explored. Results indicated that the perceptions of the help provider’s expertise, accessibility and trust were positively associated with the likelihood to seek help, frequency by which help is sought, and perceived quality of the help. Moreover, employees seem more likely to seek help upward from higher status individuals and less likely downward from lower status individuals. Employees perceived the help of higher status individuals as more useful and constructive. These results highlight the importance of investing in the strength of relationships, ensuring the accessibility of expertise and fostering a work environment, in which employees trust and respect each other. Furthermore, the results suggest valuable and promising avenues for future research and practice.  相似文献

Complex adaptive information flow and search transfer analysis     

Szabolcs?Feczak  Liaquat?HossainEmail author  Sven?Carlsson 《知识管理研究与实践》2014,12(1):29-35

Studying information flow between node clusters can be conceptualised as an important challenge for the knowledge management research and practice community. We are confronted with issues related to establishing links between nodes and/or clusters during the process of information flow and search transfer in large distributed networks. In the case of missing socio-technical links, social networks can be instrumental in supporting the communities of practice interested in sharing and transferring knowledge across informal links. A comprehensive review of methodology for detecting missing links is provided. The proportion of common neighbours was selected as best practice to elicit missing links from a large health insurance data set. Weights were based on geographical arrangements of providers and the dollar value of transactions. The core network was elicited based on statistical thresholds. Suspicious, possibly fraudulent, behaviour is highlighted based on social network measures of the core. Our findings are supported by a health insurance industry expert panel.  相似文献

Visualising Famagusta: interdisciplinary approaches to the study of the Orthodox Cathedral of Saint George of the Greeks in Famagusta,Cyprus     

Sven J Norris  Michael JK Walsh  Thomas A Kaffenberger 《档案与原稿》2014,42(1):48-60

This paper explores a recent interdisciplinary project which brought together a visualization expert, an art historian, and an architectural historian, to study the ruins of Saint George of the Greeks Cathedral in Famagusta, eastern Cyprus, then create a virtual three-dimensional reconstruction of it. The motivation for this work, funded by Nanyang Technological University in Singapore, was to apply existing knowledge and expertise to a difficult, and very particular, heritage question on this Eastern Mediterranean Island. The creation of such a model could, it was felt, not only reiterate the academic value of thorough archival work married to state of the art technology, but also have very practical reverberations in terms of future heritage welfare and education via this ‘borderless’ domain.  相似文献
