Do field position and playing standard influence athlete performance in wheelchair basketball?

Improved understanding of mobility performance in wheelchair basketball is required to increase game performance. The aim of this study was to quantify the wheelchair-athlete activities of players in different field positions and of different playing standard during wheelchair basketball matches. From video analysis, absolute and relative duration and frequency of wheelchair movements and athlete control options were examined in 27 national standard and 29 international standard players during entire wheelchair basketball matches. Between-group factorial analysis of variances identified that national players drove more forward (42.6 ± 6.8 vs. 35.4 ± 3.7%; effect size Cohen’s d (ES) = 1.48) and started more often driving forward (33.9 ± 2.6 vs. 31.8 ± 2.8; ES = 0.77) during a match while the mean activity duration for a single driving forward activity was longer (4.3 ± 0.9 vs. 3.7 ± 0.6 s; ES = 0.75) than for international players. Furthermore, national players performed fewer rotational movements (21.8 ± 4.0 vs. 28.9 ± 7.8%; ES = –1.30) and started less often with the rotational movements (35.0 ± 3.6 vs. 40.5 ± 5.5; ES = –1.21) while the mean activity duration for a single rotation activity was shorter (2.1 ± 0.3 vs. 2.3 ± 0.3 s; ES = –0.67) than for international players. Differences in mobility performance among guard, forward and centre players were minimal. The results should help wheelchair basketball coaches specify wheelchair-handling training techniques and means to optimise wheelchair-athlete configurations.     

Aspired Convergence,Cherished Diversity: Dealing with the contradictions of Bologna

This article addresses the inherent tension in the Bologna process between the aim of convergence and the will to maintain the diversity of national higher education (HE) systems, as well as the decentralised and autonomous nature of national policy formulation on Bologna reforms. Starting from an analytical discussion of the concepts of convergence versus diversity in the Bologna documents, it assesses empirically the degree of convergence achieved so far between the HE systems of Germany, the Netherlands, France, and England. The result is that convergence in several dimensions was only modest between 1998 and 2004. The article concludes by reflecting upon this finding and discusses the implications. The policy proposals put forward are (1) to acknowledge and stress the merits of the Bologna process other than convergence, (2) to engage in a second round of reforms more clearly targeted at convergence, and (3) to address mobility and recognition issues independent from convergence of degree structures.

     

Transformation and contextualisation: conceptualising students’ conceptual understandings of threshold concepts in calculus

Research on student learning in higher education suggests that threshold concepts within various disciplines have the capacity to transform students’ understanding. The present study explores students’ understanding in relation to particular threshold concepts in mathematics—integral and limit—and tries to clarify in what sense developing an understanding of those threshold concepts involves a transformation of understanding in relation to ways of thinking in mathematics. Drawing on data collected in interviews with students taking a basic course on calculus the analysis offers an initial characterisation of students’ understandings as algorithmic. It then proceeds to construct a more fine-grained theoretical account for how these understandings develop in the course of the interview, suggesting that the transformative aspects of threshold concepts may be conceptualised in terms of shifts in students’ contextualisations allowing the development of conceptions at different levels of abstraction simultaneously interacting to shape students’ awareness of the ways of thinking and practising in the subject.     

Intercultural learning in English as foreign language instruction: The importance of teachers’ intercultural experience and the usefulness of precise instructional directives

The development of intercultural competence, especially in foreign language instruction, is considered a key goal of teaching in German schools. The present article sheds light on the teaching of intercultural topics in the context of English as a foreign language (EFL). It presents the results of an analysis of data from a larger study (DESI study – Assessment of Student Achievements in German and English as a Foreign Language) bringing the intercultural experience of teachers and observable aspects of instruction into focus. Videotapes of EFL-classroom instruction of 9th and 10th grade students are analyzed in order to assess characteristic of the implementation of intercultural topics. The study reveals the impact of teachers’ intercultural experience on the quality of their intercultural instruction. Furthermore, the results indicate that precise external directives for particular lessons can help teachers put intercultural topics into practice.     

Acculturative stress in Latino Immigrants: The impact of social, socio-psychological and migration-related factors

The purpose of this study was to investigate factors that predict acculturative stress in a nationally representative sample of Latino migrants. The participants in this study were 2059 Latinos. Among them were 868 Mexicans, 577 Cubans and 614 other Latinos. The subcategory other Latinos consisted of immigrants and refugees from Colombia, the Dominican Republic, El Salvador, Ecuador, Guatemala, Honduras, Peru and Nicaragua. The participants took part in face-to-face interviews, which were conducted with computer-assisted interviewing software in Spanish and English. Findings revealed that acculturative stress decreases with an increase in the English proficiency index, the context of migration exit index, and the social network index. Furthermore, acculturative stress was lower for US citizens versus non-citizens; immigrants who wanted to migrate to the US versus refugees who had to leave their country of origin; and later generation immigrants. Acculturative stress increases with a higher native language proficiency index and a higher discrimination index.     

Perimeters of,and challenges to,the jurisdiction of Swedish special educators: an exploration of free text responses

Special needs educators (SNEs) have important roles in many education systems. However, their roles are often poorly defined, and differ greatly both between and within education systems. Studies show that SNEs have diverse tasks, have problems defining their jurisdiction, and approach special support with different perspectives than other professions. Here, the aim is to explore what Swedish SNEs express regarding their occupational role and jurisdiction, utilising 676 free text responses to an open question in a total population survey. The results illustrate that SNEs often have to take on tasks they do not view as appropriate and that they often experience misunderstanding from head teachers and colleagues about their roles and tasks, and that they risk being replaced by other professions. Some explanations can be found in vague legal definitions of their jurisdiction and the necessity of adaption to the local school context. The results are interpreted using Abbott’s theory of jurisdiction and Evetts’ distinctions of professionalisation and professionalism. The study confirms results from prior research to a high degree but adds further nuance and dimensions to them with formulations from active professionals.
