In spite of technical developments, electronic publishing in science and technology has had a slow start. This is caused by several factors, essentially managerial in character, such as standardization of text and image representation, quality assurance, the filing of reference versions, charging, and copyright control. Furthermore, in spite of the growth of the networked R&D community, not all users have easy access. Many of these problems are reduced in an area where much of the primary information proceeds via not‐yet‐copyrighted preprints, which are largely produced by advanced text‐processing techniques and put on “electronic bulletin boards”. Reports on some recent advances in this area, creating a direct access to bibliographic data and full‐text documents via a central OPAC and a distributed system of document servers.

This paper focuses on academic, scientific publishing, as a form of documentation and communication of scientific findings in the changing world of converging information and communication technologies. It assesses the current state of technologies and forms of publishing electronically, and future trends and possibilities. This is linked to a discussion of the nature of the publishing industry, its form in relation to economic issues in demand and supply within publishing and specifically electronic publishing in this area. The paper suggests that the recent policy document from the European Commission, Strategic Developments for the European Publishing Industry towards the Year 2000 may present a number of difficulties for the scientific publishing industry. This strategy outlines a number of possibilities for increasing the extent of electronic publishing. These possibilities conflict with the particular situation of scientific publishers, which are generally small businesses with limited resources and expertise, and without the financial stability to be able to set up or initiate electronic publishing. The analysis of the policy suggests that the publishing industry and its representatives may need to work more closely with small publishers, so that the infrastructure may be developed to overcome these problems for these exciting new technologies, and methods of utilising them for electronic publishing, exchange of information and communication, to be fully utilised.

The purpose of this paper is to provide a description of the SCOAP³ model, aiming to achieve a transition of peer‐reviewed literature of an entire field, high‐energy physics to open access.

An historical survey of publishing patterns in high‐energy physics puts open access in that discipline in context. A detailed, quantitative study of the publishing landscape in high‐energy physics is discussed, providing the economic basis for the SCOAP³ model.

The yearly publication output of high‐energy physics is concentrated on six journals by four publishers. This relatively compact publication landscape and the historical cohesion of the community make a transition of the entire field to open access feasible.

The results relate to a very specific field with a high potential for migration to open access. In open access there is no “one‐size‐fits‐all” solution, and other fields have to proceed to similar analyses to identify their most convenient model on the road to open access journals.

The SCOAP³ initiative seems to be a sustainable way for a transition to open access of scientific publishing of an entire discipline. It could serve as an example, and an experiment, in the search for viable business models for open access.

The paper provides an insight into the design of a business model for open access around the particular needs and publication landscape of a particular discipline.

A parametric spline function approximation is used to study the steady combined convection of a Boussinesq fluid contained between two concentric rotating spheres. A spline function which depends on a parameter p > 0 is used for approximation. This approximation gives second order accuracy. The spheres which form the flow region are maintained at uniform but different temperatures and are allowed to rotate about a common vertical axis with different angular velocities. A uniform gravitational field acts in the direction parallel to that of the axis of rotation. The resulting flow patterns, temperature distributions, total heat flux and torque characteristics are presented for various cases considered and it is found that these results are in good agreement with the results of Dallman and Douglass in 1980.

The term neurodiversity is used to discuss human neurological variation, differences in human cognition, and a social movement that aims to change the way that society views and responds to people who are neurodivergent. While the cognitive differences associated with autism are often discussed in terms of deficits, in recent years autistic autism researchers have been reframing autistic cognition from a neurodiversity-affirming lens that illuminates autistic strengths. Based on characteristics of autistic cognition from a neurodiversity-affirming perspective, this chapter describes neurodiversity-affirming autistic social entrepreneurship and systems thinking approaches and argues that all autistic-owned and -led businesses that align with the mission of the neurodiversity movement are by definition social enterprises. It is hoped that this chapter will assist in reframing autistic cognition from its current deficit conception and encourage the development of business support services that are more appropriate for autistic social entrepreneurs.

Social scientists often speculate that both acculturation and socioeconomic status are factors that may explain differences in the body weight between Mexican Americans and whites and between Mexican Americans and Mexican immigrants, yet prior research has not explicitly theorized and tested the pathways that lead both of these upstream factors to contribute to ethnic/nativity disparities in weight. We make this contribution to the literature by developing a conceptual model drawing from Glass and McAtee’s (2006) risk regulation framework. We test this model by analyzing data from the 1999–2012 National Health and Nutrition Examination Survey (NHANES). Our conceptual model treats acculturation and socioeconomic status as risk regulators, or social factors that place individuals in positions where they are at risk for health risk behaviors that negatively influence health outcomes. We specifically argue that acculturation and low socioeconomic status contribute to less healthy diets, lower physical activity, and chronic stress, which then increases the risk of weight gain. We further contend that pathways from ethnicity/nativity and through acculturation and socioeconomic status likely explain disparities in weight gain between Mexican Americans and whites and between Mexican immigrants and whites. Study results largely support our conceptual model and have implications for thinking about solutions for reducing ethnic/nativity disparities in weight.

The study was conducted to investigate the impact of competitive entrance exams on some lifestyle factors that may lead to body weight gain. The paper aims to discuss these issues.

A cross-sectional study was conducted on high school students (n=660), aged 16-20 years, to assess changes in body weight and fat percentage, dietary habits and physical activity practicing before and after the examination.

During the examination period, both males and females experienced weight gain, but the mean change of body weight for males was higher compared to the mean change of body weight observed in females (3.6 vs 0.6 kg). Body fat percentage increased in males and females in approximately 2 and 0.3 percent, respectively. In addition, males were found to skip breakfast (p=0.003) during the examination period as compared to females (p=1.00). Both males and females reported an increased consumption of milk (p=0.007 and 0.001), junk food (p=0.0001 and 0.001), caffeinated beverages (p<0.001) and carbonated drinks (p=0.001). A significant proportion from each gender reported that they quit recreational physical activity during the examination period (p=0.0001).

Several studies were conducted to investigate the impact of academic exams on stress among this vulnerable group; however, the relationship of body weight and obesity is still lacking in this population. Therefore, this study aims to investigate impact of competitive entrance exams on some lifestyle behaviours that may lead to body weight gain.

Given their history of preparing African Americans, ethnic minorities, and first-generation college students for careers in education, the culture and traditions of Historically Black Colleges and Universities (HBCU) can provide insight into the preparation of diverse physical educators for the cultural, linguistic, and ethnic diversity in today’s American K-12 schools. As such, this chapter will present practical findings from an ethnographic study of a historically Black urban Physical Education Teacher Education (PETE) program with a large native Spanish-speaking population. Specifically, we focus on the concepts of cultural sustainment and code-switching as strategies used by teacher educators to promote bilingualism and biculturalism. To achieve this, we highlight the relationship among institutional, programmatic, and classroom cultures for the cultural ­sustainment and development of preservice physical educators. According to Paris (2012), culturally sustaining pedagogy seeks to perpetuate and foster linguistic, literate, and cultural pluralism as part of the democratic project of schooling. We conclude with strategies on how to successfully work with culturally diverse college students, promoting bilingual and biculturalism through cultural sustainment and code-switching.

The purpose of this review was to highlight the association between ID and obesity in toddlers and preschool children.

This review aimed to review and evaluate literature of the published research discussing the relationship between ID and overweight and obesity in children under the age of 5 years. Conflicting results of iron status in overweight and obese children under the age of 5 years had been found. However, most articles concluded that ID is associated significantly with overweight and obesity in children because of the systemic inflammatory reaction which is considered the major cause of ID; hepcidin with its resultant effect in decreasing duodenal absorption of iron; in addition to other causes including dietary and genetic factors.

Conflicting results of iron status in overweight and obese children under the age of 5 years had been found, but most articles concluded that ID is associated significantly with overweight and obesity in children, with systemic inflammatory reaction being the major cause through hepcidin with its resultant effect in decreased duodenal absorption of iron, in addition to other causes including dietary and genetic factors.

Many nutrients have been associated with weight gain and ID development. Unbalanced diet either in excess or shortage may affect weight status and serum iron profile. Future research is needed to study more in depth the association between ID and obesity in toddlers and preschool children and to further explore the various factors involved in pathogenesis of ID.
