Analysis of Open Access Landscape

This paper is created by bounding 5 editorials of Public Library of Science （PLoS） which have written on various aspects of open access. It covers wide range topics of important open access issues, such as from paying for open access to copyright to open access as a public issue, which may be more or less of interest of our audience.     

Knowledge-based information management: implications for information services

The 1994 Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) standards for information management will change the way health care librarians respond to JCAHO accreditation surveys and may affect the way libraries are managed. This article will highlight the changes in the standards and the new opportunities they offer. Implications for library operations and the challenges inherent in working with the new Accreditation Manual for Hospitals (AMH) are also explored. The long-awaited 1994 Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) Accreditation Manual for Hospitals (AMH) is now on most hospital library shelves. As expected, librarians will find that the section on Professional Library Services (the PR chapter) has disappeared and that the standards previously in that section are now incorporated in part into the new Management of Information, or IM chapter. Although this method of grouping standards may be new to many health sciences librarians, the incorporation of library services into IM may actually provide many more opportunities for librarians than the previous method of addressing library services separately.     

Pragmatic citing and linking in electronic scholarly publishing

The transition from traditional, paper‐based publishing to electronic publishing presents many challenges for publishers and their constituents. Among the most significant are those that concern linking to articles that are available online and citing of articles that are now published online prior to (or even in lieu of) the final pagination and binding of paper issues. The solutions to these problems will have a great impact on the usability of the scholarly electronic corpus for the research community. In particular, the solutions must be easy to use, persistent, and scalable. Here we examine some pragmatic solutions (in use now) that satisfy these criteria and contrast them with other proposed solutions. The examples are drawn mainly from the experiences of the American Physical Society, but the lessons gleaned will have wide applicability.     

Review of comparative studies in the instruction of students with moderate and severe handicaps

Systematic instructional strategies that investigators have used with students who display moderate to severe handicaps were identified and defined. The investigations which directly compared two or more strategies were analyzed, and summary statements/recommendations about the relative effectiveness and efficiency of the strategies were made. Analyzing the effectiveness of the procedures involved determining which strategies successfully taught skills to subjects. The efficiency of the strategies was analyzed on measures which indicated the skills were taught in a productive and timely manner (i.e., trials to criterion, sessions to criterion, errors to criterion, direct instruction time). Recommendations for future research and practice include (a) conduct more studies comparing the effectiveness and efficiency of instructional strategies, (b) conduct investigations of the specific variables of single strategies to identify the most efficient use of each procedure, (c) expand the efficiency measures to assess whether students learn information not directly targeted for instruction, and (d) conduct research to determine which strategy is best to use with given types of students and skills.     

Trajectories of perinatal depressive symptoms in the context of the COVID-19 pandemic

This study sought to advance understanding of the potential long-term consequences of the COVID-19 pandemic for child development by characterizing trajectories of maternal perinatal depression, a common and significant risk factor for adverse child outcomes. Data came from 393 women (86% White, 8% Latina; mean age = 33.51 years) recruited during pregnancy (n = 247; mean gestational age = 22.94 weeks) or during the first year postpartum (n = 146; mean child age = 4.50 months; 55% female). Rates of depression appear elevated, relative to published reports and to a pre-pandemic comparison group (N = 155). This study also provides evidence for subgroups of individuals who differ in their depressive symptom trajectories over the perinatal period. Subgroup membership was related to differences in maternal social support, but not to child birth outcomes.     

Educational performance or educational inequality: what can we learn from PISA about France and England?

This article evaluates PISA 2000 as a resource for providing information on educational attainment and inequality, focusing on France and England. Going beyond pupils' performance, it assesses levels of educational inequality by examining distributions of scores and the relationship between socio‐economic status and performance. This review raises methodological issues which could hamper the comparison of performance. The prioritising of ‘skills for life’ over curriculum‐based questions, together with PISA's sampling on the basis of pupils' age rather than their class/grade, works to the advantage of the English performance. The issue of low response rates in England is also raised and care is urged with regard to ranking the performance of France and England on the basis of these results. The article concludes that as a tool for comparing average performance PISA has drawbacks, but for assessing levels of inequality it is a useful resource.     

Developmental patterns in security of attachment to mother and father in late childhood and early adolescence: associations with peer relations

This study examined developmental differences in two dimensions of attachment security (parental availability and child dependency on parents) in late childhood (N = 274) and early adolescence (N = 267) and their association with peer relations. Children's perceptions of mother's availability and boys' perceptions of father's availability did not differ as a function of age. Dependency on parents, however, decreased with age. Findings highlight the importance of distinguishing between parental availability and reliance on parental help when measuring attachment developmentally. Children's reports of positive friendship qualities and lack of conflict in their best friendships were related to attachment to both mother and father, whereas the presence of a reciprocated friendship and popularity were not. Father availability was a particularly important predictor of lower conflict with best friends. Findings indicate that the quality of parent-child attachment generalizes primarily to the quality of children's close peer relations.     

Operationalising pedagogical content knowledge research in technology education: Considerations for methodological approaches to exploring enacted practice

Like many areas of curricula internationally, technology education has encountered difficulties in achieving continuity between the rhetoric of prevailing policy and the reality of enacted practices. In technology education, the conceptually oriented nature of curricular goals is theorised to play a significant part in influencing this relationship. One way in which investigations of this relationship have been approached is considering the application of pedagogical content knowledge (PCK) frameworks as a mechanism to understand the interaction of teachers’ knowledge and enacted practices. However, understanding from the philosophy of technology, and the technology education literature, suggests that technology education treats knowledge differently to many other disciplines. As a result of this, the interactions between teachers’ beliefs and knowledge are theorised to play a more significant role in influencing enacted practice in technology education. Building on this perspective, this article considers the need to investigate the roles of teachers’ knowledge and beliefs, and the interactions between these, in the investigation of enacted practice. Further to this, the article problematises the potential for a dominance of exploratory research, though acknowledging the need for research within different paradigms; a common frame of reference is advocated. In advocating a more holistic approach to investigating enacted practice, and the factors which may influence teachers’ enactment of teaching practice, it is envisioned that this article takes a step towards methodological coherence regarding the study of enacted practice in technology education.     

Comparison of force-related performance indicators between heavyweight and lightweight rowers

The aim of this study was to examine biomechanical variables relating to the force production of men's Lightweight (LW) and Heavyweight (HW) rowing pairs. Seven HW and seven LW coxless pairs were studied under a range of stroke rates, from 20 spm to race rating (average of 33.7 spm for the HWs and 33.9 spm for the LWs). Each crew was equipped with biomechanical apparatus allowing the measurement of gate force, horizontal oar angle, and boat velocity. The HW crews exhibited significantly higher (p < 0.05) values for all variables examined, at all rates. Peak handle force was 26.2% to 30.2% higher in the HW group. Average handle force ranged from 18.7% to 22.1% higher than the LW group. Work per stroke was found to be 26% to 28% higher for the HW crews, and Power Per Kilogram was also greater for the HW crews, from 24.0% to 29.2%. The LWs were observed to be consistently, but not significantly, slower than the HWs (from 96.9% at the race situation, to 98.7% at 28 spm). These observations are important when considering biomechanical performance indicators in rowing, as significant changes in performance indicators may lead to only minimal alteration in boat velocity.
