Phonological working memory: A critical building block for reading development and vocabulary acquisition?

In this article we review findings from a recent longitudinal study of the contribution of phonological working memory to vocabulary acquisition and reading development. A total of 80 children were tested initially at school entry at the age of four years, and were tested in three further waves at ages 5, 6, and 8 years. The results indicate that phonological memory skills constrain vocabulary growth during the first year or so in school but that subsequently, vocabulary knowledge is a pacemaker in the development relationship with memory. Phonological memory skill in prereading children was found to be significantly linked with scores on a reading test at age 8 which encourages the use of a phonological recoding strategy. The theoretical and practical implications of the findings, and important areas for future research, are discussed.     

Development of an exchange format for the European Environmental Chemical Data and Information Network (ECDIN)

Increasing concern about the release of potentially harmful chemicals into the environment has led to efforts to collect data on such chemicals with a view to identifying and minimising the associated hazards. The collection and storage of such data requires cooperation and communication (both national and international) between partners in a general environmental data network. A format is described for the exchange of data between these network partners. This format is of general applicability. It is shown that a hierarchical tree structure best describes the situation. Rules are derived to identify and process the nodes in the tree such that information is neither lost nor degraded upon transfer between the network partners.     

Mothering in Families With and Without a Child with Disability

This paper describes some features of a study which compares and contrasts mothers’ perceptions of their family life in three different family environments, those without a child with disability and those families who live with a child with an intellectual or physical disability. All families have children in the middle childhood period allowing the mothers to reflect on earlier experiences and changes in their family life. Mothers’ psychological characteristics are explored in terms of the coping resources they utilise when meeting stressful life situations in their family and how their personal resilience and vulnerability is related to these individual coping resources.     

An International Study of Prospective Teachers’ Initial Teaching Conceptions and Concerns: the case of teaching ‘combustion’

An important task of science teachers should be to take pupils’ (pre)conceptions and learning difficulties into account and to negotiate about the meanings of specific concepts. In this context, teachers’ pedagogical content knowledge plays an important role. This article presents an international study of Dutch, Finnish, English and Greek pre-service teachers’ conceptions and concerns of how to teach the concept of combustion. The prospective science teachers were invited to prepare a lesson about this concept for pupils of junior secondary school level. The prospective teachers were not allowed to consult any textbook. Research data were obtained from audio-taped semi-structured interviews with the prospective teachers. In addition, their written lesson plans and their answers to an accompanying questionnaire were collected and analysed. The results reveal a number of important characteristics of prospective teachers’ views and concerns regarding the teaching of combustion. The implications of the study for science teacher education will be presented.     

Dynamic Transition Patterns in Acculturation Among Hispanic Adolescents

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, M_age (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed.     

The Intergrated Museum: A Meaningful Role in Society?

Abstract This article describes a process initiated in 1983, at the Canadian Museum of Nature (CMN), which was based on the premise that a responsible natural history museum should assist society in shaping its collective future. The museum predicted that if it were able to help people understand themselves and their relationship to the natural world, the museum would again be seen as valuable to society, and thus would be supported in its efforts. The CMN therefore began to integrate its collections, scholarship, discovery, public programming, and public exhibits into broad, institution‐wide programs focused on the needs and interests of society. These programs enabled the museum to engage its visitors in “guided conversations” in which the museum provided the content, drawing on the research and communication strengths of the museum, while the audience, representing society, set the context. This guided conversation empowered the public to make informed decisions and to influence the museum and its work. CMN also designed exhibit formats that allowed the visiting public to contact industry and government decision‐makers with their opinions. The article describes the museum's evolution through several stages of increasing internal and external integration, ultimately using a managerial matrix to form project teams, with discipline‐based professionals focused on the interests and needs of society. Drawing on audience participation, the CMN reset its programming and offered advice and counsel to government and industry. The museum also took the first steps to include the traditional knowledge of indigenous peoples as an additional source of wisdom about the natural world. Financial and other support grew rapidly, effectively demonstrating a successful programmatic feedback loop helping society to shape its future using the museum as an information source and communication tool. The effort was terminated before the integration was completed, but nonetheless, CMN demonstrated that is possible to achieve a programmatic feedback loop that includes collections, science, exhibits, the general public and both government and industry decision‐makers.     

Division of labour and sharing of knowledge for synchronous collaborative information retrieval

Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques.     

The relationship between hostile attributional bias and aggressive behavior in preschoolers

Previously, K.A. Dodge and colleagues found an association between hostile attributional bias and aggressive behaviors among school aged children. The present study explored such an association among preschool aged children. Sixty-eight children (38 girls and 30 boys) with a mean age of 4.76 years participated in the study. Videotaped vignettes of children's social interactions were developed specifically for this age group to examine their attributional bias. Children's aggressive behaviors were assessed by teachers, using the Preschool Behavior Questionnaire. Results indicated that hostile/aggressive children were significantly more likely to possess a hostile attributional bias (p < .05) than less aggressive children. Results also indicated that preschoolers were capable of distinguishing between intentional and unintentional actions when stimulus materials used were concrete and familiar to them.     

Some grammatical rules are more difficult than others: The case of the generic interpretation of the masculine

In this paper we argue that the generic use of the masculine represents a grammatical rule that might be easy to learn but difficult to apply when understanding texts. This argument is substantiated by reviewing the relevant literature as well as the recent work conducted by the GREL Group (Gender Representation in Language) on the interaction between stereotypical and grammatical information in the construction of a representation of gender when reading role names. The studies presented in this paper show that the masculine form used as a generic to refer to persons of both sexes, or to persons of indefinite sex or whose sex is irrelevant, in gender marked languages is likely to be associated with its specific meaning (i.e., masculine refers only to men). This is true even though the generic nature of the masculine is a very common grammatical rule learnt at school. People may have learned this rule and may understand it, but may not readily apply it.
