Navigating the Information Landscape

This article explores the tension between the structures by which the library organizes and presents information, and the ways in which students and researchers access, use, and conceptualize knowledge. I suggest that while knowledge structures are vital to learning and research, an overemphasis on structurality is mistaken, and can lead to an inappropriately positivist approach that impedes the research mission. The article examines various metaphoric ways of negotiating meaning and navigating information structures, and of crossing the threshold of structurality.     

Challenges Facing the UK Book Industry

This abstract examines the challenges facing the UK publishing industry, as well as the opportunities brought by the advent of digital. The article makes reference to key facts and statistics which illustrate the value of the market, and the publishing market is discussed in terms of its categories: consumer publishing, academic and STM publishing, and children’s publishing. The importance of copyright to the business and the developing role of the publisher are examined, as are industry initiatives taking place in the UK to help raise awareness of the diminishing bricks and mortar retail sector. The work performed by publishers and authors participating in initiatives tackling illiteracy and encouraging reading for pleasure as an activity is discussed.     

Peak power output provides the most reliable measure of performance in prolonged intermittent-sprint cycling

Abstract

The aims of this study were to determine the reliability of an intermittent-sprint cycling protocol and to determine the efficacy of one practice session on main trials. Eleven men, moderately trained team-sport athletes, completed three visits to the laboratory involving a graded-exercise test and practice session and two trials of a Cycling Intermittent-Sprint Protocol separated by three days. Data for practice and main trials were analysed using typical error of measurement, intra-class correlation and least-products regression to determine reliability. Typical error of measurement (expressed as a coefficient of variation) and intra-class correlation for peak power output from all 20 sprints for trial 1 and trial 2 were 2.9 ± 12.8% (95% confidence interval: 2.0–5.0%) and 0.96 (95% confidence interval: 0.85–0.99), respectively. Typical errors of measurement and intra-class correlation for mean power output for all 20 sprints for trials 1 and 2 were 4.2 ± 11.9% (95% confidence interval: 2.9–7.4%) and 0.90 (95% confidence interval: 0.66–0.97), respectively. The results suggest that peak power output provides a more reliable measure than mean power output. The Cycling Intermittent-Sprint Protocol provides reliable measures of intermittent-sprint performance.     

A reciprocal effects model of the temporal ordering of motivation and burnout among youth table tennis players in intensive training settings

Abstract

Using self-determination theory (SDT) (Deci, E.L., & Ryan, R.M. (1985). Intrinsic motivation and self-determination in human behavior. New York, NY: Plenum) as the theoretical framework, we conducted a longitudinal investigation of the temporal ordering between motivation and burnout among youth athletes in intensive training setting. Data were collected from 145 table tennis players in intensive training centres at three time points during a 2-month period characterised by a simultaneous increase in social, physical and psychological demands for these athletes. Structural equation modelling of cross-lagged panel models was used to test the hypotheses. Results showed significant paths leading from athlete burnout – especially sport devaluation and reduced sense of accomplishment – at time 1 to amotivation, intrinsic and extrinsic motivations at times 2 and 3. Only two significant paths leading from motivation (introjected regulation at time 1) to burnout (emotional/physical exhaustion at time 2 and reduced sense of accomplishment at time 3) were identified. Overall, our results suggest that athlete burnout predicts motivation over time but motivation did not predict athlete burnout over time. Results are discussed in terms of current research findings on SDT.     

Working on What Works: working with teachers to improve classroom behaviour and relationships

The Working on What Works (WOWW) approach, which is based upon Solution-focused Brief Therapy, was implemented in a mainstream primary classroom over a 10-week period. The focus was on improving behaviour and relationships in class. Results demonstrated an improvement in teacher ratings for targets set by the class teacher compared with baseline. Pupils also set, and rated themselves on class targets. Observation of pupils, and their class-ratings, demonstrated a positive impact for these targets. Longer term follow-up suggested that this positive impact was maintained. It is concluded that WOWW had a positive impact on behaviour and relationships within this classroom.     

Promoting staff support in schools: Solution Circles

The Solution Circle (SC) approach is a flexible tool which encourages participants to maintain a positive, creative approach to problem-solving. This project focussed on the introduction of this approach to staff in a primary and a secondary school. The rationale was to implement a problem-solving/discussion tool that would allow staff to utilise expertise present within the school before looking to outside agencies for support. In both schools staff participants reported positively about the process, highlighting its potential use to promote the inclusion of pupils with a wide range of needs.     

On the Rebound: Critical Race Praxis and Grassroots Community Organizing for School Change

This ethnographic research was conducted over a three-year period, and documents the efforts of a committed group of parents and community members who through community-based research sought to address the disproportionate underachievement of African American students within their city??s public school system. Specifically, the parents and community members who make up the group Parents of Children of African Ancestry (POCAA) offer a refreshing theory of action that explicitly addressed issues of racial inequity, and called upon the larger community to respond with the urgency the youth deserved. In effect, POCAA challenges dominant views of African American parents and re-envisions their involvement in school reform as a site of radical resistance.     

Chemical Laws, Idealization and Approximation

This paper examines the notion of laws in chemistry. Vihalemm (Found Chem 5(1):7–22, 2003) argues that the laws of chemistry are fundamentally the same as the laws of physics they are all ceteris paribus laws which are true “in ideal conditions”. In contrast, Scerri (2000) contends that the laws of chemistry are fundamentally different to the laws of physics, because they involve approximations. Christie (Stud Hist Philos Sci 25:613–629, 1994) and Christie and Christie (Of minds and molecules. Oxford University Press, New York, pp. 34–50, 2000) agree that the laws of chemistry are operationally different to the laws of physics, but claim that the distinction between exact and approximate laws is too simplistic to taxonomise them. Approximations in chemistry involve diverse kinds of activity and often what counts as a scientific law in chemistry is dictated by the context of its use in scientific practice. This paper addresses the question of what makes chemical laws distinctive independently of the separate question as to how they are related to the laws of physics. From an analysis of some candidate ceteris paribus laws in chemistry, this paper argues that there are two distinct kinds of ceteris paribus laws in chemistry; idealized and approximate chemical laws. Thus, while Christie (Stud Hist Philos Sci 25:613–629, 1994) and Christie and Christie (Of minds and molecules. Oxford University Press, New York, pp. 34--50, 2000) are correct to point out that the candidate generalisations in chemistry are diverse and heterogeneous, a distinction between idealizations and approximations can nevertheless be used to successfully taxonomise them.
