Abstract

By the metric of average home attendance, the Portland Thorns of the National Women’s Soccer League are the most popular women’s professional sports team in the world. This paper investigates that distinct sports context through a mixed-methods case study of Thorns fandom, asking what fans themselves perceive to be salient elements of a successful fan culture for women’s professional soccer and what motivates their fandom. Drawing on survey data that are contextualized by ethnographic observations and interviews, we offer an interpretive analysis of ways Thorns fandom hybridizes elements of traditional and alternative sports fandom. Our findings highlight the emphasis Thorns fans put on quality soccer in a professional atmosphere where fans themselves create the supporters culture, along with the symbolic importance to fans of identifying with values such as gender empowerment, diversity and inclusion. We discuss ways these themes might offer and inform alternative models of sports fandom.  相似文献

BACKGROUND: This study was undertaken to provide evidence that library outreach projects in the NHS in the Thames Valley Strategic Health Authority area were effective and could justify continued funding. Objectives: The object was to assess whether information literacy skills training taken up by health professionals impacts on their confidence and skills in using electronic sources of health information. METHOD: A total of 487 health professionals taking up training on a voluntary basis were assessed by completing a self-assessment questionnaire prior to and after training to establish their information literacy skills and confidence levels. Of these, 223 trainees (46%) also returned 6-week follow-up questionnaires. RESULTS: Results showed that 464 trainees (95%) intended to apply what they had learnt in a variety of ways; use of specific resources greatly increased after training and confidence in using them increased substantially. Use of search techniques increased considerably overall, whereas use of Google decreased. CONCLUSIONS: The major findings of this research are that training health-care personnel in the use of electronic resources impacts positively on their information literacy skills and confidence, and that the information available to them is considered to have potential value across health-care practice.  相似文献

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.  相似文献

Our study compares the motivations of Australian and German book publishers. The results demonstrate remarkable similarities, but also a significant difference regarding the effects of the publishers’ self-concept. In the German case the publishers with a dominant economic orientation are more proactive than the publishers with a dominant cultural orientation. In the Australian case, this correlation does not exist. The same difference holds for the relationship between the economic orientation and extrinsic motivation. We discuss these results and examine empirical evidence and theoretical suggestions to explain the differing findings. The data stem from surveys conducted in the two countries with responses of 196 (Germany) and 54 publishers (Australia).  相似文献

This study explores how preschool storytimes in public libraries in Aotearoa New Zealand incorporate practices which have been identified as beneficial for children's early literacy skills. The results of observations of storytimes in four public library services are reported, focusing on whether they included activities that foster six key literacy skills: print motivation; phonological awareness; vocabulary; narrative skills; print awareness and print concepts; and letter awareness. The results indicate that the storytimes observed focused strongly on techniques to increase children's print motivation, and other skills, such as the development of letter awareness, did not feature as frequently. It is suggested that the librarians leading the sessions were wary of introducing more formal instructional elements into the storytimes because they felt it might detract from the main aim of the sessions, which was to encourage children to enjoy books and reading.  相似文献

This study explores the long-term impact on participation in the Linda Ray Intervention Program (LRIP) for children (n = 54) who were developmentally delayed and prenatally exposed to cocaine. By identifying a group of programme graduates from a high crime/high poverty neighbourhood in Miami-Dade County using ArcGIS 10.2 software, a quasi-experimental design was used to compare children living in this area who participated in the centre-based modality (5 h a day; 5 days a week) to children living in this area who participated in the home-based modality (3 h per week) on their Florida Comprehensive Assessment Test (FCAT) reading and math scale scores in public school. The children who participated in the centre-based modality reported stronger outcomes in both math and reading FCAT scale scores at the p < .05 level and also out-performed their school-age peers on both math and reading FCAT scores at the p < .05 level.  相似文献

This paper examines the causes of pupil mobility and good practice in schools to address mobility issues. Pupil mobility is defined as ‘a child joining or leaving school at a point other than the normal age at which children start or finish their education at that school’. The first part draws upon evidence of a survey, which explores the views of headteachers on the nature and causes of pupil mobility in schools and the priority they give to addressing pupil mobility issues in their schools. It examines the cause of mobility in schools in the context of mobile groups. This is followed by the challenges for managing mobility and strategies to address pupil mobility in schools. The second part of the paper outlines successful strategies that minimize the effects of mobility in schools. Evidence is drawn from case‐study research and focuses on the school systems, pastoral care and access to learning which combine to support the induction, assessment and monitoring of newly arrived pupils in school and effective use of data for self‐evaluation. Examples of flexible curriculum organization, innovative approaches to additional support and effective administrative procedures are drawn upon. Evidence reflects the views of a range of school staff, parents/carers and pupils in the case‐study school, as well as the judgements of senior researchers. Policy implications for government and for all concerned with school performance are highlighted, as well as many practical suggestions for raising achievement of mobile pupils  相似文献

This study built on prior research regarding the effectiveness of the National Center for Research in Early Childhood Education (NCRECE) course by exploring the individual course components. Core aspects of course engagement and performance were described and examined in relation to improvements in the observed quality of teacher–child interactions. Teacher characteristics were also examined as predictors of course engagement and performance. A sample of 150 preschool teachers participated in a semester-long, credit-bearing, college course designed to improve the quality of their emotional, organizational, and instructional interactions with children. Teachers’ participation and performance in the course were high on average. Teachers’ skill level in accurately and specifically explaining other teachers’ instances of effective teacher–child interactions was related to improvements in their own observed teacher–child interactions. Finally, teachers with an early childhood major and those endorsing child-centered beliefs displayed better skills in detecting other teachers’ high-quality interactions with children. Results are discussed in relation to designing more effective early childhood professional development programs.  相似文献

Although a large number of different organisations offer various forest education programmes within Germany, specific information (i.e., sectoral and programme content and provision at a state level) is lacking. This study used a survey of all 61 forest education organisations (43 respondents) in the state of North Rhine‐Westphalia, Germany, to evaluate its forest education sector, with a specific focus on the organisations, demand for its services, forest educational programmes and framework conditions. Input from expert interviews was also used to develop recommendations. The study indicates that, especially with children as the main target group, many non‐formal programmes are offered to support the formal environmental education sector and to promote leisure activities in the forest. Yet, despite a high demand for forest education, low personnel resources restrict the number of visits and activities, principally owing to limited financial resource. We also discuss the provision of innovative new educational programmes and supplementary services, combined with increased quality management, that could be beneficial to the future development of the sector in NRW.  相似文献
