Mired in the shadows: quiet students in secondary schools

Quiet students are a feature of the organisation of secondary schools. Using qualitative methods and Deleuzean conceptualisations of modern subjectivity, this paper explores the ways that quiet students negotiate the terrain of their school. These negotiations often seem to produce a self that is trapped rather than a subject who seizes opportunities to be inventive, creative and experimental of their self. Understanding the faciality of quiet students provides opportunities to advance debate on how schools could encourage freer selves.     

Electronic detection of dielectrophoretic forces exerted on particles flowing over interdigitated electrodes

Dielectric particles flowing through a microfluidic channel over a set of coplanar electrodes can be simultaneously capacitively detected and dielectrophoretically (DEP) actuated when the high (1.45 GHz) and low (100 kHz–20 MHz) frequency electromagnetic fields are concurrently applied through the same set of electrodes. Assuming a simple model in which the only forces acting upon the particles are apparent gravity, hydrodynamic lift, DEP force, and fluid drag, actuated particle trajectories can be obtained as numerical solutions of the equations of motion. Numerically calculated changes of particle elevations resulting from the actuation simulated in this way agree with the corresponding elevation changes estimated from the electronic signatures generated by the experimentally actuated particles. This verifies the model and confirms the correlation between the DEP force and the electronic signature profile. It follows that the electronic signatures can be used to quantify the actuation that the dielectric particle experiences as it traverses the electrode region. Using this principle, particles with different dielectric properties can be effectively identified based exclusively on their signature profile. This approach was used to differentiate viable from non-viable yeast cells (Saccharomyces cerevisiae).     

The relative effects of group size on reading progress of older students with reading difficulties

This study reports findings on the relative effects from a yearlong secondary intervention contrasting large-group, small-group, and school-provided interventions emphasizing word study, vocabulary development, fluency, and comprehension with seventh- and eighth-graders with reading difficulties. Findings indicate that few statistically significant results or clinically significant gains were associated with group size or intervention. Findings also indicate that a significant acceleration of reading outcomes for seventh- and eighth-graders from high-poverty schools is unlikely to result from a 50 min daily class. Instead, the findings indicate, achieving this outcome will require more comprehensive models including more extensive intervention (e.g., more time, even smaller groups), interventions that are longer in duration (multiple years), and interventions that vary in emphasis based on specific students’ needs (e.g., increased focus on comprehension or word study).

The evolution of Web‐based peer‐review systems

Web‐based peer‐review systems are ubiquitous within scholarly publishing today, providing valuable efficiencies for authors, editors, and referees. These systems are the result of a general evolution from paper‐based workflows to electronic processes that began in the 1970s. DOS‐based systems paved the way for Windows desktop systems and, in the mid‐1990s, Web‐based peer review. Governmental, academic, and commercial stakeholders all participated in advancing the state of peer review by experimenting with different technologies, workflows, and features. These experiments have coalesced into a new steady state in which Web‐based peer‐review systems are the norm, and in which continued evolution tends to focus on incremental improvements to traditional workflow.     

Tensions in Community Health Improvement Initiatives: Communication and Collaboration in a Managed Care Environment

Between the years 1993 and 2000, the W. K. Kellogg Foundation sponsored the Comprehensive Community Health Models (CCHMs) Initiative in three Michigan counties. CCHMs was comprised of three closely related community initiatives carried out in the midst of a failed national health care reform effort and the continued penetration of managed care arrangements into many health care systems. This experimental initiative set out to test the hypothesis that traditional healthcare system animosities and exclusionary practices could be overcome by stakeholder participation in an ongoing, structured, collaborative dialogue about improving access to health services. In the process of collecting data through surveys, interviews, content analysis, and observation, we were struck by the occurrence of several overarching tensions that we perceive to exist in our data. The present article elucidates five such tensions and suggests how third parties such as communication researchers, evaluators, and practitioners can facilitate community health improvement initiatives and better their own data interpretation by acknowledging and understanding these tensions.     

Attentional Load and the Reproduction of Physical Work

Abstract

The effect of attentional focus on the perception of physical work was examined by using a work reproduction design. Subjects performed a fixed interval of work at either 50 or 75% of their predicted VO₂ max, during which they were required either to solve a continuous flow of arithmetic problems or to perform in an unfilled control condition. On a subsequent trial, without a concomitant attention-demanding task, subjects were asked to reproduce the amount of work that they had previously performed. It was found that individuals in the control condition produced a significantly greater amount of work on the reproduction trial, while those in the attentional focus condition performed about the same amount as on the previous trial. No interaction was found between attentional focus and work load.     

Physiological responses and time-motion characteristics of various small-sided soccer games in youth players

The aim of this study was to examine acute physiological responses and time-motion characteristics associated with three different small-sided soccer game formats in youth players. Sixteen male soccer players aged 16.3+/-0.6 years (mean+/-s) completed three variations of a small-sided game (i.e. 2 vs. 2, 4 vs. 4, and 6 vs. 6 players) in which heart rate, rating of perceived exertion (RPE), blood lactate concentration, and time-motion characteristics were recorded. The pitch size was altered to keep the relative pitch area per player consistent for each game format. The 2 vs. 2 games exhibited greater blood lactate, heart rate, and RPE responses compared with 4 vs. 4 and 6 vs. 6 games (P<0.05). The players travelled less (P<0.05) distance at speeds of 0-7 km.h(-1) in the 4 vs. 4 compared with the 2 vs. 2 games (1128+/-10 m and 1176+/-8 m, respectively). Average maximal sprint distances above 18 km.h(-1) were lower (P<0.05) in 2 vs. 2 than in 4 vs. 4 and 6 vs. 6 games (11.5+/-3.9 m, 15.3+/-5.5 m, and 19.4+/-5.9 m, respectively), and in 4 vs. 4 compared with 6 vs. 6 games. The results show that as small-sided game formats decrease in size and relative pitch area remains constant, overall physiological and perceptual workload increases.
