Effect of a randomised 12-week resistance training programme on muscular strength,cross-sectional area and muscle quality in women having undergone Roux-en-Y gastric bypass

The purpose of this study was to examine the effect of a 12-week resistance training programme on fat-free mass (FFM), muscle cross-sectional area, muscular strength and muscle quality in women who underwent Roux-en-Y gastric bypass surgery. Participants were 16 women (mean age = 44.9 ± 10.2 years) from bariatric surgical groups who were randomly assigned into either a control or an intervention group. Air displacement plethysmography measured FFM and magnetic resonance imaging measured quadriceps muscle cross-sectional area and whole thigh muscle cross-sectional area. Muscular strength and quality was assessed using an estimated 1-Repetition Maximum assessment. All measurements were collected twice, at baseline and at a 12-week follow-up. There were significantly greater improvements in leg press strength (mean differences = 55.4%, P < 0.001, Cohen’s d = 2.4), leg extension strength (mean differences = 18.0%, P = 0.014, Cohen’s d = 0.86) and leg press muscle quality (mean differences = 54.5%, P < 0.001, Cohen’s d = 1.9) in the intervention group compared to the control group following the resistance training programme. The resistance training intervention significantly improved muscular strength and quality; however, it did not illicit changes in FFM or muscle cross-sectional area in women who underwent Roux-en-Y gastric bypass surgery.

Response strategies after overtraining in the jumping stand

Rats were trained to criterion (CT) and overtrained (OT) on a horizontal against vertical stripes discrimination in the jumping stand. A change in response strategy, from inspecting both stimuli to inspecting just the S?, was observed during overtraining. Replacing the S? with a novel stimulus disrupted performance in the OT Ss, but replacing the S+ did not. Performance in the CT Ss was disrupted, but not very severely, both when the S+ was replaced and when the S? was replaced. These results suggest that OT Ss in the jumping stand come to rely especially upon the S?. The overtraining effects found here are compared with those found in other types of apparatus.     

Promoting NQT linguistic awareness of dialogic teaching practices: a dialogic model of professional development

This study offers an insight into the experiences of three newly qualified English primary teachers and their pupils as they sought to develop dialogic teaching in lessons. It draws upon a range of literature from the field of classroom talk, with a particular focus on the work of Robin Alexander to underpin teacher/researcher professional discussion and analysis of periodic video recordings of talk in these classrooms. Supplemented by teacher interviews, the research examines the extent to which a dialogic approach to teacher professional development might facilitate teacher self‐evaluation as a means of developing a more dialogic classroom. In doing so, it seeks to exemplify key talk moves (dialogic bids) that these teachers used to open up dialogic spaces in lessons. The research concludes that raising teacher awareness of such talk moves through professional discussion and reflection upon teaching can provide teachers with a metacognitive resource for talking about and furthering dialogic teaching practices.     

The role of habituation of the response to LiCl in the US-preexposure effect

In two experiments, rats received preexposure consisting of six intraperitoneal injections of lithium chloride (LiCl). This treatment reduced the magnitude of the unconditioned response (UR; suppressed consumption of a novel flavor) evoked by an additional injection (Experiment 1) or by oral consumption (Experiment 2) of LiCl. In both experiments, preexposure also attenuated the acquisition of a conditioned aversion with an LiCl injection as the unconditioned stimulus (US) but had no effect on the aversion produced when the US was oral consumption of LiCl (Experiment 2). These results are consistent with the view that the reduced ability of the preexposed US to serve as a reinforcer depends on blocking by injection-related cues and is independent of habituation of the UR recorded in the present study. Possible interpretations of this dissociation are discussed.     

Pupil guidance: An integral part of teacher education and development in Scotland?

Many schools throughout the UK are experiencing challenging behaviour from pupils and high levels of absence and exclusion as they seek to implement initiatives aimed at raising pupil attainment [National Audit Office (2005). Improving school attendance, London: The Stationery Office]. These initiatives often presuppose that pupils will receive adequate levels of guidance and support to help them make curricular, personal, social, and health decisions. However, little is heard from teachers and students undertaking initial teacher education courses on how they have been prepared for this extended role of supporting increasing diverse student populations; nor do we know how they define guidance/pupil support and integrate this with their concept of the professional role of a teacher. This article presents evidence from a one-year study of pupil support in Scotland commissioned by the Scottish Executive Education Department. The study provided evidence for The National Review of Guidance Provision in Scotland [Scottish Executive (2003). The national review of guidance. Edinburgh: Scottish Executive; Scottish Executive (2005). Happy, safe and achieving their potential. Edinburgh: Scottish Executive]. The study explored the views of all 32 local authorities in Scotland, a sample of students in training in two universities and teachers, headteachers and pupils in eight case study schools, and also a sample of their parents. This article focuses specifically on the findings relating to teachers and students in training. It identifies the ways in which they support pupils and how well they think they have been prepared for that task. Two dominant models of pupil support emerge from these data: an embedded and a specialist approach, and these vary according to school and education sector. Primary school teachers were more likely to embed pupil support into their concept of being teachers, whereas secondary teachers perceived it to be a separate, specialist function, which many were reluctant to undertake. Some implications for teacher education are highlighted.     

The Bleaching Syndrome: The Role of Educational Intervention

Per the Bleaching Syndrome, people of color, including African, Asian, and Latino Americans, are both victims and perpetrators of color discrimination. The Bleaching Syndrome encompasses perceptual, psychological, and behavioral sectors that affect students' schooling experiences. Education professionals, including teachers, administrators, and counselors, must address these factors to promote mental and emotional health among learners. In this article, I discuss how the Bleaching Syndrome and color bias affects dark-complexioned African American children in contemporary US schools.     

Assessing Developmental Education Policies

This paper reviews the results of a research study designed to assess the effectiveness of the policies governing the developmental education program at a comprehensive community college. The major issues addressed in the study are required remediation of skill-deficient students, enrollment in college-level courses by skill-deficient students, and differing policies for skill-deficient students depending on the extent of deficiency. The results point to guidelines for designing or revising policies governing developmental education programs. A recently implemented student tracking system was used to conduct this comprehensive and in-depth analysis of student enrollment patterns, persistence, and performance.
