Co-authorship networks in the digital library research community

The field of digital libraries (DLs) coalesced in 1994: the first digital library conferences were held that year, awareness of the World Wide Web was accelerating, and the National Science Foundation awarded $24 Million (US) for the Digital Library Initiative (DLI). In this paper we examine the state of the DL domain after a decade of activity by applying social network analysis to the co-authorship network of the past ACM, IEEE, and joint ACM/IEEE digital library conferences. We base our analysis on a common binary undirectional network model to represent the co-authorship network, and from it we extract several established network measures. We also introduce a weighted directional network model to represent the co-authorship network, for which we define AuthorRank as an indicator of the impact of an individual author in the network. The results are validated against conference program committee members in the same period. The results show clear advantages of PageRank and AuthorRank over degree, closeness and betweenness centrality metrics. We also investigate the amount and nature of international participation in Joint Conference on Digital Libraries (JCDL).     

School-based sexuality education in Portugal: strengths and weaknesses

Portugal, like many other countries, faces obstacles regarding school-based sexuality education. This paper explores Portuguese schools’ approaches to implementing sexuality education at a local level, and provides a critical analysis of potential strengths and weaknesses. Documents related to sexuality education in a convenience sample of 89 schools were analysed and findings confirm both the results of the few existing Portuguese studies on the subject and commonalities in sexuality education between Portugal and other European countries. These include strengths, such as the existence of teams in charge of sexuality education in schools and the provision of resources, but also weaknesses, such as too heavy a focus on health-related issues, difficulties in cross-curricular teaching, low levels of community participation and poor-quality evaluation. Findings point to the need for a greater sharing of information and good practice between countries, and the need for clearer guidelines. Suggestions are made for improving the quality of sexuality education in Portuguese schools.     

A Study of Home Emergent Literacy Experiences of Young Latino English Learners

This empirical study explored the home environment literacy practices of young Latino English learners and their families. The participants were 217 incoming Kindergarten Latino EL students and parents. The data collection included a completed HLEQ by the parents. In addition, children were administered the PPVT, the preLAS, the PALS-K screening, the Woodcock Reading Mastery assessment, and the Wide Range Achievement test. All of the literacy assessments given to the children provided the researchers with comprehensive look at their literacy knowledge base. The results of this study indicate that there were two significant paths for students’ achievement: availability of books and child initiated literacy factors that were directly related to the phonological processing efforts of students.     

History, Myth, and the Politics of Educational Reform

This paper analyzes the politics of education in the United States by considering the ideas and lives of Emma Willard and Catharine Beecher, nineteenth century educational reformers. It argues that understanding these women as American Antigones, as working through the contradictions between their public writing and their private lives, provides a perspective on the history of educational reform that combines myth and history. This perspective refuses idealized accounts of "lost" moments or possibilities in the past, grounding educational reform in the project of reimagining gender relations within families and schools in the present.     

Deciding for themselves

World Education, in a collaboration with PfP/International and with funding from US AID, has begun comprehensive program in Kenya that offers non-governmental organizations non-formal training, technical assistance in organization and business management, and financial assistance in the form of loans for revolving credit funds. The approach emphasizes Kenyans deciding for themselves about the directions projects should take. This article discusses the Tototo Home Industries' rural economic development program. After receiving a loan from Tototo, the women of Bofu village planned to stock their small village shop with matches, kerosene, soap, salt, and cooking oil. The remainder of the loan was saved to purchase future stock. For this project, bookkeeping and management skills were necessary. To meet this need, the Tototo small business advisor designed a simple cash boom system to be used by all the groups. Sessions in accounting were included in the annual training of trainers workshop. Currently, accounts advisor visit the groups monthly to provide follow-up training and assistance to ensure the women understand how to record project transactions accurately. The lesson to be drawn from these projects is simple. It is not unrealistic to set high expectations for project participants, but it is important to remain aware of the difficulty of the new concepts presented to these groups. In order for them to adequately master both concept and practice, the participants must be given sufficient time and support. In fact, consistent follow-up and close contact with the villages is the key to Tototo's success.     

Programs for the promotion of family wellness and the prevention of child maltreatment: a meta-analytic review

OBJECTIVE: The objectives were to determine the effectiveness of programs in promoting family wellness and preventing child maltreatment and to identify factors that moderate program success. METHOD: Meta-analysis, employing a 3-step model testing procedure, was used to review 56 programs designed to promote family wellness and prevent child maltreatment. RESULTS: The effect sizes for proactive interventions were larger at follow-up than at post-assessment, while the effect sizes for reactive interventions were higher at post-assessment than follow-up. The lowest effect sizes for home visitation programs on child maltreatment were for programs with 12 or fewer visits and less than a 6-month duration. Intensive family preservation programs with high levels of participant involvement, an empowerment/strengths-based approach, and a component of social support had higher effect sizes than programs without those elements. Also, both home visitation and intensive family preservation interventions achieved higher effect sizes with participants of mixed socioeconomic status (SES) than participants with low SES. CONCLUSIONS: The total mean weighted effect size was .41, indicating that outcomes for the intervention group exceed 66% of those in control/comparison groups. The findings from this review demonstrated that child maltreatment can be prevented and that family wellness can be promoted.     

Effect of a Single Day's Swimming on Selected Components of Athletic Performance

Abstract

The purpose of this investigation was to study the effect of swimming on selected components of athletic performance as measured by the following tests: back strength, leg strength, bicycle ergometer (combination of strength and endurance, but predominantly endurance), and vertical jump (explosive power). Subjects were pretested for three days on each test, after which they participated in 45 minutes of swimming, and performance was tested oh one test one hour after the swim on any given day. A single day's swimming was found to significantly affect the vertical jump, but other performance tests were not affected.
