Comparison of the traditional problem-based learning format and larger, directed, independent study groups

 Problem based learning has been implemented as a pedagogical tool world-wide across a range of health professions since its inception at McMaster University, Canada, in 1969 (Neville & Norman, 2007). In addition to enhancing knowledge and understanding it is also claimed that PBL develops communication skills, encourages teamwork, sharing of information and respect for others, furthers problem solving skills, and allows students to assume responsibility for their own learning (Wood, 2003). However, the cognitive outcomes of PBL and traditional pedagogy (based on didactic teaching) are similar and hence widespread adoption of PBL has been questioned (see Colliver, 2000). Criticisms of PBL include its resource hungry nature, requiring, as it does, experienced tutors to facilitate .learning across several clusters of students dealing with the same problem. Given the actual and anticipated increase in numbers of medical students in Australia other strategies that retain the advantages of PBL, while minimising the demands on faculty, should now be explored. This paper reports our experience with a modification of the traditional PBL approach, termed PBLplus. This innovation was trialled in a regional clinical school, attached to a hospital, with a group of 19 graduate entry students, who had completed an integrated Year 1 / 2 of the MBBS. PBLplus involved allocating students from the whole class to three task directed groups. Groups had specified assignments to complete to facilitate learning across the whole class. A tutor listened to student presentations and provided an interactive presentation. Hence use of tutors was made more efficient, and faculty input was more specialised.

Concepts and factors influencing independent learning in IS higher education

The concepts of independent learning (IL), self-directed learning (SDL) and self-regulated learning (SRL) have been widely used in relation to students’ learning success. Often, these terms are interrelated and used interchangeably in the literature with regards to students’ learning process. The purpose of this paper is (1) to promote conceptual clarity by having clear definitions of SRL, SDL and IL and (2) to provide a review of research related to the development of students’ SRL at higher education particularly in the context of Information Systems studies. The findings from the literature reveal that mastering the process self-regulation progressively leads to self-directed and independent learning. The literature review on SRL reveals that students’ academic self-regulation is influenced by their personal processes such as cognitive knowledge and motivational beliefs and also external processes such as lecturers and instructions in higher education.

Managerial share ownership and operating performance : do independent and executive directors have different incentives?

We investigate the relationship between managerial share ownership (MSO) and earnings as a measure of operating performance in Australia. To mitigate potential earnings management, we also use discretionary accrual adjusted earnings as an alternative measure of performance. We document a negative relation between MSO and performance followed by a positive relation. We suggest that these unique results are an artefact of certain Australian institutional features and imply that the ownership–performance relation is context-specific, with the wider corporate governance systems influencing the theorised incentive effects. We also posit that executive directors and independent directors have different ownership–performance incentives. Our results are consistent with this proposition and suggest that independent directors may be immune to the theorised incentive alignment or entrenchment effects associated with share ownership.

Raised CRP levels in obese patients : symptoms of depression have an independent positive association

Background: Depression and obesity, the two common ailments of modern society, are associated with increased risk of coronary artery disease and raised C-reactive protein (CRP) levels. Are the effects of depression and obesity related or do they influence CRP levels independently?

Objective: In 493 consecutive patients presenting for obesity surgery, we explored the relationship between symptoms of depression and raised CRP levels after controlling for confounding factors.

Methods and Procedures: Depression was measured using the Beck Depression Inventory (BDI). Confounding variables were age, gender, BMI, waist and hip measures, smoking and alcohol habits, medications, biochemical measures of the metabolic syndrome, and indirect measures of insulin resistance. General linear regression sought variables independently associated with CRP levels.

Results: These patients had a BMI range from 31 to 91 kg/m2, participants age ranged from 14 to 71 years, and 76% were women. The median CRP concentration was 7.7 mg/l (interquartile range: 3.9–14), 40% had an abnormally raised concentration (>10 mg/l). The mean BDI score was 17.0 ± 9.0, indicating symptoms of moderate depression. We found five independent factors associated with raised CRP levels. In order of strength of association, these were: higher BMI (β = 0.36, P < 0.001), female gender (β = −0.19, P < 0.001), estrogen therapy (β = 0.18, P < 0.001), higher BDI score (β = 0.11, P = 0.01), and insulin resistance index (β = 0.11, P = 0.01), and with a combined R 2 = 0.24, (P < 0.001). Discussion: In obese patients, symptoms of depression were associated with raised CRP levels after controlling for confounding variables. Obese women on estrogen therapy are at risk of high CRP levels.

What is a cinema? Death, closure and the database

This chapter explores the possible ontological questions and epistemological propositions that arise from detailed empirical research into cinema closures. Repeated pronouncements of the ‘Death of Cinema’ in the wake of technological, social and industrial change serve to reinforce the coincidence of ‘death’ with a type of ‘closure’. The evocation of a ‘crisis’ in the cinema is ordinarily articulated within the terms of specific cultural concerns around transience and transformation in the social experience of the cinema. However, rather than adding another chapter to the apocalyptic historiography of the cinema this paper proposes instead the constitutive importance of ‘closure’ as a critical tool for rethinking our defining assumptions about cinema(s). Specifically, the chapter will demonstrate how the conceptual granularity entailed in the development of a detailed database of venue openings and closings (the Cinema and Audiences in Australia Project database) can in turn lead to a fundamental reconsideration of the ontology of the cinema itself.
