Anorexia athletica in pre-professional ballet dancers

Competitive sport has been under increasing discussion as a possible favourable factor in the development of eating disorders among children and adolescents. The aim of this study was to determine the frequency of sport-specific eating disorders, in line with the concept of anorexia athletica. This prospective field study included one experimental group and two control groups (disease and healthy). Fifty-two pre-professional ballet dancers aged 13-20 years were tested for clinical eating disorders, anorexia athletica criteria, eating disorder related psychopathology and self-concept, and were compared with 52 patients with anorexia nervosa and 44 non-athletic controls of the same age. The study was conducted using semi-structured interviews as well as self-report questionnaires. A clinical eating disorder diagnosis was made in 1.9% of the ballet dancers versus 0% of the high school students; anorexia athletica was diagnosed in 5.8% of the dancers versus 2.3% of the students. Ballet dancers scored lower than patients with anorexia nervosa with regard to eating disorder related psychopathology and higher than the patients with regard to self-concept. We conclude that more sensitive tools to differentiate between sport-specific (eating) patterns, anorexia athletica and clinically relevant eating disorders are needed, especially for aesthetic sports such as ballet. It remains an important goal to identify athletes with symptoms of anorexia athletica irrespective of their physique and/or sport.     

Does the accuracy matter? Accurate concept map feedback helps students improve the cohesion of their explanations

Students are often challenged by the demand of writing cohesive explanatory texts. Prior research has shown that providing students with concept map feedback that visualizes explanatory cohesion deficits helped students generate more cohesive explanations. We conducted an experiment to investigate whether the accuracy of the provided information within the concept map feedback affected students’ improvements of cohesion. Accordingly, we varied the represented accuracy of information within such concept maps: Students either received accurate concept map feedback that depicted the real relations between concepts, as well as the authentic cohesion gaps in their explanations, or students received inaccurate concept map feedback, which depicted randomly drawn relations and random cohesion gaps. Additionally, in a baseline condition, students did not receive any feedback. We found that the students in the accurate feedback condition generated more cohesive explanations than the students in the no-feedback condition, whereas the students in the inaccurate feedback condition lay in-between. Evidently, providing feedback in general can be regarded as beneficial to enhance students’ writing. However, the accuracy of the provided feedback further impacts the effectiveness of computer-generated concept maps.     

A study of the metadata creation behavior of different user groups on the Internet

Metadata is designed to improve information organization and information retrieval effectiveness and efficiency on the Internet. The way web publishers respond to metadata and the way they use it when publishing their web pages, however, is still a mystery. The authors of this paper aim to solve this mystery by defining different professional publisher groups, examining the behaviors of these user groups, and identifying the characteristics of their metadata use. This study will enhance the current understanding of metadata application behavior and provide evidence useful to researchers, web publishers, and search engine designers.     

Assessing the impact of a program designed to develop sustainability leadership amongst staff members in higher education institutes: a case study from a community of practice perspective

This study focuses on the impact of a sustainability leadership development program (SLDP) designed to develop staff members as leaders who encourage sustainability practices within institutions of higher education (IHE). Using the framework of community of practice (CoP), we explored the program’s contribution by interviewing 16 staff members who had attended the program. At the individual level, we found that the SLDP provided participants with opportunities to learn from and with other members of the CoP and to engage them in debate about the various meanings of ‘sustainability’, increasing their environmental awareness and their environmental involvement within the IHE’s community. At the institutional level, the SLDP disseminated the college’s socio-environmental mission statement, increased its administration’s commitment and involvement, served as a platform for addressing local socio-environmental problems and initiated an Education-for-Sustainability (EfS) activists’ network. However, the participants indicated that the SLDP had limited impact on the environmentalism of other staff members and that the on-going mentoring and support from the college administration was insufficient. This study highlights the importance of such EfS professional programs to the development of both staff members and entire institutions as sustainability leaders. It also suggests ways to increase staff involvement in institutional EfS discourse.     

Making ‘place’ for ecological sustainability in early childhood education

Culturally, childhood is often understood as a time of innocence which can mean that issues such as ecological sustainability are considered too problematic for early childhood practice. By drawing on findings from a research project that focused on issues of ecological sustainability in early childhood centres in New Zealand from Western and indigenous perspectives, this article contributes a critical perspective of ecological sustainability as an educational issue in early childhood education (ECE). The article falls into two parts: the first section gives an overview of some of the conceptual and theoretical issues that underpin critical perspectives of childhood, and provides a context for current global ECE discourse, while the second section introduces the research project and discusses the intersections of ‘local’ and ‘global’ in light of teachers’ emerging ‘pedagogies of place’. The intent is to demonstrate that critical engagement with such complex global issues as ecological sustainability generates spaces for new understandings of how ECE can contribute to theory and practice of education for sustainability.     

Der Personalstrukturplan im System des Universitätsgesetzes 2002

Seit der Periode 2010–2012 verpflichten die Leistungsvereinbarungen zwischen den Universitäten und dem Bund, die Universitäten Personalstrukturpläne zu erstellen. Personalstrukturpläne sind in erster Linie interne Instrumente zur strategischen Personalentwicklung. Sie sind teils komplementär und teils konkretisierend zu den Entwicklungs- und Organisationsplänen der jeweiligen Universitäten. Extern dienen sie dem Bundesministerium für Wissenschaft und Forschung als Informationsressource. Der Beitrag untersucht die rechtliche Stellung des Personalstrukturplans im System des Universitätsgesetzes 2002.

E-book as facilitator of vocabulary acquisition: support of adults,dynamic dictionary and static dictionary

We investigated the effects of three facilitators: adults’ support, dynamic visual vocabulary support and static visual vocabulary support on vocabulary acquisition in the context of e-book reading. Participants were 144 Israeli Hebrew-speaking preschoolers (aged 4–6) from middle SES neighborhoods. The entire sample read the e-book without a dictionary once, and was pretested on receptive word comprehension, expressive word explanation and word production in story retelling. The sample was then randomly divided into four groups, each reading an e-book three times, with: (1) adults’ vocabulary support; (2) dynamic visual dictionary support; (3) static visual dictionary support; or (4) without support. The participants were then posttested on the same measures. Children’s progress in all measures was dependent on group, with adults’ support appearing as most effective, dynamic dictionary as second, static dictionary as third, and no support as least effective. However, the gains differed significantly only between some of the groups, but were always significantly different between the group given adults’ support and the control group which was given no support. We conclude that e-books can be used effectively to facilitate word meaning acquisition at different levels. This contribution can be augmented by adults’ support and dynamic dictionary support.
