Institutional Repositories: An Analysis of Trends and a Proposed Collaborative Future

This study seeks to give libraries a plan for interinstitutional cooperation for institutional repositories that will benefit all involved: researchers, institutions, and, ultimately, global scholarship. This research uses repository studies, interviews with existing repository managers, and the input of libraries considering a repository to inform the exploration of the opportunities for collaboration in IR development and maintenance. This article proposes opportunities for collaboration between institutions in order to convince libraries that it is possible and effective to work together toward a common goal: highlighting existing working groups or alliances, sharing technology and hardware, building separate interinstitutional bodies to house repositories, and sharing the work of specialists.     

Oral reading fluency and comprehension in Kenya: reading acquisition in a multilingual environment

Reading research has shown that variable relationships exist between measures of oral reading fluency and reading comprehension, depending on whether the language of the text is the reader's first language or an additional language. This paper explores this phenomenon, using reading assessment data for 2,000 Kenyan children in two or three languages: English, Kiswahili and one of two mother tongues, Dholuo or Gikuyu. The assessment data allowed us to compare reading and comprehension rates across languages. The data indicated that many children could read English words more easily than words in Kiswahili or their mother tongue; nevertheless, their reading comprehension was significantly lower in English than in Kiswahili, Dholuo or Gikuyu. The paper concludes that emphasising English reading fluency is an inefficient route to gaining reading comprehension skills because pupils are actually attaining minimal oral reading fluency in English and only modest comprehension skills in their own languages. The evidence also demonstrates that Kenya's national language policy of mother tongue as a medium of instruction in the early primary grades is consistently ignored in practice.     

Contextualizing Nature of Science Instruction in Socioscientific Issues

The purpose of this study was to investigate the effects of two learning contexts for explicit-reflective nature of science (NOS) instruction, socioscientific issues (SSI) driven and content driven, on student NOS conceptions. Four classes of 11th and 12th grade anatomy and physiology students participated. Two classes experienced a curricular sequence organized around SSI (the SSI group), and two classes experienced a content-based sequence (the Content group). An open-ended NOS questionnaire was administered to both groups at the beginning and end of the school year and analyzed to generate student profiles. Quantitative analyses were performed to compare pre-instruction NOS conceptions between groups as well as pre to post changes within groups and between groups. Both SSI and Content groups showed significant gains in most NOS themes, but between-group gains were not significantly different. Qualitative analysis of post-instruction responses, however, revealed that students in the SSI group tended to use examples to describe their views of the social/cultural NOS. The findings support SSI contexts as effective for promoting gains in students’ NOS understanding and suggest that these contexts facilitate nuanced conceptions that should be further explored.     

Electrical and mechanical response of skeletal muscle to electrical stimulation after acute passive stretching in humans: A combined electromyographic and mechanomyographic approach

Abstract

Flexural and torsional rigidity are important properties of skis. However, the flexural and torsional rigidity that lead to optimal performance remain to be established. In the present study, four pairs of slalom skis that differed in flexural and torsional rigidity were tested by advanced and expert skiers. Using a 10-item questionnaire, different aspects of the skis' performance were rated on a 9-point scale. For each pair of skis, physical measurements were compared with the ratings of the two groups of skiers. Correlations (Spearman) were then determined between (i) different mechanical properties of the skis (static and dynamic), (ii) subjective assessments of the participants, and (iii) properties of the skis and the participants' assessments. The latter showed that expert skiers rate the aspects of the skis more accurately than advanced skiers. Most importantly, expert skiers are particularly sensitive to torsion of the skis. These results suggest that such highly rated elements should be addressed in future ski designs.     

Examining Undergraduate Students' Priorities for Academic Library Services and Social Media Communication

Academic libraries can effectively plan and market their services by identifying the value users perceive in their services and in their social media communications about those services. This study reports on findings of a survey of 104 undergraduate students in information technology courses at a large research university. Results of an ordered logistic regression analysis indicated that students considered access to information and computer resources and study support services as the most important library services offered. Likewise, students perceived library social media postings related to operations updates, study support services, and events as the most useful. Future related research will investigate the needs and priorities for library services of other key user populations of academic libraries, such as graduate students and online students, to assemble service repertoires that are tailored to individual user groups. In addition, future research will examine whether and how libraries can use the analysis of users' engagement with a library's social media postings to inexpensively gauge the value they perceive in library services.     

Beliefs about justification for knowing when ethnic majority and ethnic minority students read multiple conflicting documents

We examined the role of justification for knowing beliefs in learning and comprehension when ethnic majority and ethnic minority students from the same school classes read five conflicting documents on the scientific issue of sun exposure and health. Results showed that the more ethnic minority students trusted scientific authorities and the less they relied on personal opinion when validating knowledge claims in the domain of science, the more they learned from and the better they comprehended the documents. In contrast, justification for knowing beliefs did not seem to play a role in learning and comprehension among ethnic majority students. These results may reflect that the documents represented more of a challenge to the ethnic minority students, with justification beliefs affecting learning and comprehension processes to a greater extent when the task is perceived as an ill-structured problem. This study is probably the first to indicate different relationships between various justification beliefs and performance in different language and cultural groups, having theoretical as well as educational implications.     

Conceptions of intelligence as social representations

The aim of the study was to investigate the theory put forward by Mugny and Carugati that social representations of intelligence are organised both by social identity and by experiences of unfamiliarity. Parents’, teachers’ and students’ conceptions of intelligence were examined in two separate questionnaire-based studies, the first one (N=196) dealing with views on the development of intelligence, and the second one (N=222) with views on the definitions of intelligence. It was found that social identity (“fostererhood” and teacherhood) tends to organise the conceptions in terms of the “theory of natural inequalities”, as suggested by Mugny and Carugati. However, the experienced unfamiliarity of intelligence had a clear effect only on the conceptions of development, and there were no general associations between social identity and experienced unfamiliarity. We suggest that the social representations of intelligence might be organised in terms of several basic themes, with one dealing with the puzzle of development, another with the definition of intelligence, and a third, more general one, treating the whole concept of intelligence with suspicion and apprehension.
