Social correlates of sedentary behavior in young people:The UP&DOWN study

Purpose:The aim of the present study was to analyze the associations of youths' sedentary behavior(SB) with parents' and siblings' SB and physical activity(PA),as well as the associations of youths' coparticipation with parents,siblings,and friends in PA and SB with youths' SB.Methods:The sample consisted of 1543 youths(12.02±2.51 years;788 boys) enrolled in the baseline cohort of the UP&DOWN study.SB was assessed by accelerometry and questionnaire.Participants reported the time spent by their parents and siblings watching television,playing videogames,surfing the Internet,sitting/resting,and doing PA.Further,participants reported coparticipation with parents,siblings,and friends in these activities.Linear mixed models,including school and city as random effects,were performed.Results:Parents' television time was positively associated with youths' screen-based SB.Coparticipation with friends in playing videogames(in boys) and in surfing the Internet(in girls) showed a positive association with screen-based SB and a negative association with educational-based SB.Moreover,coparticipation with siblings and friends in PA was inversely associated with accelerometer-based SB in boys and girls.Conclusion:Our results emphasize the important role of social modeling in the development of sedentary lifestyles in youths.Interventions aimed at reducing health risk behaviors in youths could be more effective if they are oriented from a social perspective that involves their families and networks of their closest friends.     

Multicultural Education Within the Era of Internalization and Globalization

In this article, the author presents the results of a multistate study examining how teachers, and specifically secondary English Language Arts (ELA) teachers, conceptualize and implement teaching for social justice in standards-based contexts. Additional analysis underscores how this practice both reflects and extends earlier equity-oriented reform movements.     

Stress and teachers of the learning disabled,behavior disordered,and educable mentally retarded

This study investigated which factors related to the professional roles of teachers of the learning disabled (LD), behavior disordered (BD), and educable mentally retarded (EMR) are most stressful, and which activities, both personal and professional, are beneficial in guarding against stress. The Special Teacher Response to Environmental Stressors (STRESS) was used to elicit responses from the 135 teachers who participated in the study. The participants rated as highly stressful legal concerns, lack of administrative and peer support, and lack of support services. In particular, teachers of the BD revealed that they were fearful of verbal and physical attacks from their students. The participants rated highly exercise and outdoor programs, confiding in significant others (i.e., wife or husband), and peer support as helpful in guarding against stress.     

Postgraduate taught students and preparedness for Master’s level study: polishing the facets of the Master’s diamond

Transitions are increasingly recognised as difficult, and less has been written about transitions to postgraduate taught programmes than about transitions into undergraduate or doctoral study. A Scotland-wide project found that new taught Post-graduate (PG), and staff teaching them, can be unclear about what is expected at Master’s level, and proposed a framework of seven facets that indicate how students are expected to engage with Master’s study. The facets and accompanying resources were designed to be discussion tools, to promote staff and student discussion of what is expected in their programme and subject. In a follow-up project at one university, a questionnaire was designed and distributed to postgraduate students asking them to rate their current level of ability against the skills and capabilities identified as facets for Master’s level study. The project found students felt ill-prepared for particular aspects of Master’s level study, with sub-group differences between disciplines. Master’s courses are intensive and fast-moving, so this has implications for students’ preparedness for successfully navigating through their programmes. Some suggestions on how students can be better briefed on what to expect are made.     

Finding the right problem

In an educational setting, a solution that has worked for one problem may not work for the same problem that occurs at a different time in a different work conditions. However, administrators and teachers resort to quick solutions to the perceived problem, consequently affecting not only the curriculum but also the students ’ learning. This paper shows how administrators and teachers can find problems prior to problem solution by taking three steps: (1) Examining the interconnectivity of things; (2) Exploring possible and alternative problems and (3) Asking the right question. The paper demonstrates not only how these steps operate in specific situations encountered by administrators and teachers but also how finding the problem can be an effective tool in performing their respective roles.     

The Home Instruction for Parents of Preschool Youngsters Program's Relationship with Mother and School Outcomes

Research Findings: This study investigated the relationship of the Home Instruction for Parents of Preschool Youngsters (HIPPY) program to mothers' involvement in education at home and school, student school readiness in kindergarten, and student academic outcomes at 3rd grade. HIPPY serves a mostly minority, low-income family population and employs home visitors that are mostly female and Spanish speaking. Using a within-group analysis, we found that HIPPY mothers increased educational activities in their home with their children after 1 year of home-based intervention. The majority (84.8%) of HIPPY kindergartners were rated as “ready for school” by their kindergarten teachers according to a within-group analysis. In addition, between-group analyses showed that HIPPY kindergartners had higher attendance rates, higher prekindergarten enrollment, and higher promotion to 1st grade compared to other kindergartners in the school district. HIPPY 3rd graders scored significantly higher on a state-mandated math achievement test than their matched peers. Practice or Policy: The results suggest that HIPPY had a positive relationship with families and schools through improved parent involvement and student school outcomes.     

Distributed search based on self-indexed compressed text

Query response times within a fraction of a second in Web search engines are feasible due to the use of indexing and caching techniques, which are devised for large text collections partitioned and replicated into a set of distributed-memory processors. This paper proposes an alternative query processing method for this setting, which is based on a combination of self-indexed compressed text and posting lists caching. We show that a text self-index (i.e., an index that compresses the text and is able to extract arbitrary parts of it) can be competitive with an inverted index if we consider the whole query process, which includes index decompression, ranking and snippet extraction time. The advantage is that within the space of the compressed document collection, one can carry out the posting lists generation, document ranking and snippet extraction. This significantly reduces the total number of processors involved in the solution of queries. Alternatively, for the same amount of hardware, the performance of the proposed strategy is better than that of the classical approach based on treating inverted indexes and corresponding documents as two separate entities in terms of processors and memory space.     

Key workers and schools: meeting the needs of children and young people with disabilities

Across the world countries are advocating the education of children and young people with disabilities in mainstream schools. There is also increasing interest in developing effective coordination of the specialist services pupils with disabilities receive from different agencies. This is accompanied by growing recognition that such care coordination can positively influence the experience of inclusion for children and their families. However, while the literature of care coordination generally includes education as a core provider, there is little evidence on involvement of education professionals and the outcomes for children and schools. These issues are addressed by the findings reported here on the role of key workers in care coordination and their relationship with schools. The findings draw on interviews with professionals from seven key worker services across England and Wales, parents and carers who were recipients of these services and teachers in schools serving children supported by key workers. These interviews are part of a wider multi‐method study exploring the effectiveness and costs of different models of key worker services for disabled children. The data reveal the range of education and school issues addressed by key workers and the factors influencing their work with teachers. The benefits for children, families and schools of key worker involvement are identified and the implications for schools explored. Consideration is also given to the advantages and disadvantages of teachers themselves taking on the role of key workers. It is argued that key workers can improve home–school relationships, facilitate the contribution of teachers in inter‐agency working, enable mainstream schools to better meet the individual needs of pupils with disabilities and improve their inclusive practice.     

Body parts removed during surgery: a useful training source

Current undergraduate medical curricula provides relatively little time for cadaver dissection. The Department of Human Anatomy and Physiology at the University of Padova has organized a pilot project with the University Hospital for the donation of body parts that are surgically removed for therapeutic purposes and destined under Italian law for destruction. The aim of the project is to improve residents' practical training skills. A survey over the last two years has shown that about 60 body parts were available each year. These included 13 upper limbs or their parts (i.e., forearm with hand, hand, and fingers) and 47 lower limbs or their parts (i.e., legs with feet, feet, or toes). The residents explained the aim of the project to potential donors, and, if patients were willing to donate, their informed consent was obtained. The residents were present in the operating theater during the surgical procedure. In the post-operative phase, the same residents performed dissections on the body part(s), following a teaching schedule prepared by a clinical anatomist, who also assisted residents during their studies. Residents also acted as tutors for undergraduate medical students who attended these dissections. The underlying pathology for which the body part was removed was examined, and surgical procedures were practiced on the body part itself. Our project provided an opportunity for a close relationship between anatomists and surgeons, reinforcing core knowledge of anatomy by appreciation of its clinical importance. The active involvement of residents as learners and as teachers in the various steps of this project improved their knowledge of surgical techniques and helped to establish a sense of ethical responsibility and respect for the human body. This approach involves study of anatomical structures from new perspectives and leads to improved surgical practice.
