The role of the learning community in the development of discipline knowledge and generic graduate outcomes

In this paper we describe a study of learning outcomes at a research-intensive Australian university. Three graduate outcome variables (discipline knowledge and skills, communication and problem solving, and ethical and social sensitivity) are analysed separately using OLS regression and comparisons are made of the patterns of unique contributions from four independent variables (the CEQ Good Teaching and Learning Communities Scales, and two new, independent, scales for measuring Teaching and Program Quality). Further comparisons of these patterns are made across the Schools of the university. Results support the view that teaching and program quality are not the only important determinants of students' learning outcomes. It is concluded that, whilst it continues to be appropriate for universities to be concerned with the quality of their teaching and programs, the interactive, social and collaborative aspects of students' learning experiences, captured in the notion of the Learning Community, are also very important determinants of graduate outcomes, and so should be included in the focus of attempts at enhancing the quality of student learning.

Mental playmates: Siblings, executive functioning and theory of mind

This study assessed the theory of mind (ToM) and executive functioning (EF) abilities of 124 typically developing preschool children aged 3 to 5 years in relation to whether or not they had a child-aged sibling (i.e. a child aged 1 to 12 years) at home with whom to play and converse. On a ToM battery that included tests of false belief, appearance-reality (AR) and pretend representation, children who had at least 1 child-aged sibling scored significantly higher than both only children and those whose only siblings were infants or adults. The numbers of child-aged siblings in preschoolers' families positively predicted their scores on both a ToM battery (4 tasks) and an EF battery (2 tasks), and these associations remained significant with language ability partialled out. Results of a hierarchical multiple regression analysis revealed that independent contributions to individual differences in ToM were made by language ability, EF skill and having a child-aged sibling. However, even though some conditions for mediation were met, there was no statistically reliable evidence that EF skills mediated the advantage of presence of child-aged siblings for ToM performance. While consistent with the theory that distinctively childish interaction among siblings accelerates the growth of both TOM and EF capacities, alternative evidence and alternative theoretical interpretations for the findings were also considered.

An n-of-1 trial service in clinical practice: Testing the effectiveness of stimulants for attention-deficit/hyperactivity disorder

OBJECTIVE. We sought to describe the clinical use of n-of-1 trials for attention-deficit/hyperactivity disorder in publicly and privately funded family and specialized pediatric practice in Australia. METHODS. We used a within-patient randomized, double-blind, crossover comparison of stimulant (dexamphetamine or methylphenidate) versus placebo or alternative stimulant using 3 pairs of treatment periods. Trials were conducted from a central location using mail and telephone communication, with local supervision by the patients' clinicians. PATIENTS. Our study population included children with clinically diagnosed attention-deficit/ hyperactivity disorder who were aged 5 to 16 years and previously stabilized on an optimal dose of stimulant. They were selected because treatment effectiveness was uncertain. MAIN OUTCOME MEASURES. Our measures included number of patients recruited, number of doctors who used the service, geographic spread, completion rates, response rate, and post-n-of-1 trial decisions. RESULTS. Forty-five doctors across Australia requested 108 n-of-1 trials, of which 86 were completed. In 69 drug-versus-placebo comparisons, 29 children responded better to stimulant than placebo. Immediately posttrial, 19 of 25 drug-versus-placebo responders stayed on the same stimulant, and 13 of 24 nonresponders ceased or switched stimulants. In 40 of 63 for which data were available, posttrial management was consistent with the trial results. For all types of n-of-1 trials, management changed for 28 of 64 children for whom information was available. DISCUSSION. Attention-deficit/hyperactivity disorder n-of-1 trials can be implemented successfully by mail and telephone communication. This type of trial can be valuable in clarifying treatment effect when it is uncertain, and in this series, they had a noticeable impact on short-term management.

Reflections on the centrality of power in medical sociology: an empirical test and theoretical elaboration

This paper explores the contemporary relevance of sociological theorisations centred on medical power, including the medical dominance and deprofessionalisation theses. To achieve this it examines two issues that have been tentatively linked to the relative decline of the power and autonomy of biomedicine - complementary and alternative medicine (CAM) and the Internet-informed patient. Drawing on these two different but interconnected social phenomena, this paper reflects on the potential limitations of power-based theorisations of the medical profession and its relationship to patients and other non-biomedically situated professional groups. It is argued that power-based conceptual schemas may not adequately reflect the non-linear and complex strategic adaptations that are occurring among professional groups.

Expression of multilectin receptors and comparative FITC-dextran uptake by human dendritic cells

Dendritic cells (DC) are potent antigen-presenting cells and understanding their mechanisms of antigen uptake is important for loading DC with antigen for immunotherapy. The multilectin receptors, DEC-205 and macrophage mannose receptor (MMR), are potential antigen-uptake receptors; therefore, we examined their expression and FITC-dextran uptake by various human DC preparations. The RT-PCR analysis detected low levels of DEC-205 mRNA in immature blood DC, Langerhans cells (LC) and immature monocyte-derived DC (Mo-DC), Its mRNA expression increased markedly upon activation, indicating that DEC-205 is an activation-associated molecule. In Mo-DC, the expression of cell-surface DEC-205 increased markedly during maturation. In blood DC, however, the cell-surface expression of DEC-205 did not change during activation, suggesting the presence of a large intracellular pool of DEC-205 or post-transcriptional regulation. Immature Mo-DC expressed abundant MMR, but its expression diminished upon maturation. Blood DC and LC did not express detectable levels of the MMR, FITC-dextran uptake by both immature and activated blood DC was 30- to 70-fold less than that of LC, immature Mo-DC and macrophages. In contrast to immature Mo-DC, the FITC-dextran uptake by LC was not inhibited effectively by mannose, an inhibitor for MMR-mediated FITC-dextran uptake. Thus, unlike Mo-DC, blood DC and LC do not use the MMR for carbohydrate-conjugated antigen uptake and alternative receptors may yet be defined on these DC. Therefore, DEC-205 may have a different specificity as an antigen uptake receptor or contribute to an alternative DC function.

An examination of the factors that influence identification and acculturation

This paper investigated the effects of print media exposure and intergroup contact on ethnic identification and acculturation attitudes of Chinese immigrants. Data was gathered from a survey participated by 265 respondents of Chinese origin. Findings indicated that exposure to the print media did not have a significant effect on ethnic identification and/or acculturation orientation. However, when the factor of intergroup contact was taken into consideration, differences began to occur. Specifically, for respondents from low intergroup contact group, ethnic identification increased with the desire to integrate into the large culture. For respondents from high intergroup contact group, opposite trends were found, i.e. as ethic identification increased, the tendency to adopt integration orientation decreased. Findings from this study suggested the need to combine factors of both interpersonal and mediated communication in the examination of ethnic identification and acculturation. This paper also drew some implications for the media industry and government policies.

COMUNICAÇÃO POPULAR-ALTERNATIVA DESENVOLVIDA POR JOVENS INDÍGENAS DAS ALDEIAS DO JAGUAPIRU E BORORÓ EM DOURADOS / MS

Trata-se de um estudo de caso em que analisamos a comunicação alternativa desenvolvida pela AJI (Ação dos Jovens Indígenas), em Dourados/MS, nas aldeias do Jaguapiru e Bororó. Os jovens, que produzem audiovisuais, fotografias, blog, fotolog e um jornal impresso, encontraram na comunicação uma alternativa ante à marginalidade com que os índios são tratados na cidade, e buscarem seus direitos à voz e ao espaço social, em suas próprias tribos, já que os jovens indígenas solteiros ocupam um não-lugar na Reserva, pois não pertencem à organização tradicional indígena, tampouco estão inseridos entre os brancos. A partir das características e limitações da comunicação alternativa no Jornal AJIndo, por meio de pesquisa bibliográfica, entrevistas semi-estruturadas e análise de conteúdo, buscamos verificar o impacto da utilização desta comunicação nas aldeias para os jovens que a produzem, levando em conta interferências nas formas tradicionais de hierarquia e comunicação entre os indígenas e a função social da comunicação alternativa para eles. Embora não seja o objetivo principal do AJIndo, destaca-se o desenvolvimento da auto-estima como resultado desse processo. Soma-se a esta função, a mobilização por transformação social e a formação crítico-educativa. Após o esforço de organização, os jovens começaram a se sentir pertencentes aos indígenas e a serem ouvidos pelos brancos, mesmo que acreditem ser por interesses políticos da comunidade como um todo.

Auditor's engagement risk and audit fees:the role of the audit firm alumni

This study explores the effect of the association of audit firm alumni with their alma mater on audit prices. The tests indicate that there is a moderate reduction of up to 21% in the level of audit fee when alumni (i.e., former employees) of the incumbent audit firm sit on the client board of directors which is consistent with the engagement risk theory. This suggests that there is an 'alumni effect' in the market for audit services. The findings hold only in the large company segment of the market. The results are robust to different model specifications and alternative samples. The sample comprises all executive and non-executive directors who run the UK quoted companies and are simultaneously ICAEW qualified chartered accountants. The study's implications for the accounting profession and the regulators are also discussed. © 2007 The Author Journal compilation © 2007 Blackwell Publishing Ltd.

A comparative study of HR practices in Britain and India

This paper traces the major developments in the field of human resource management briefly and then highlights the need for more cross-national HRM studies. The results from two parallel surveys of matched Indian and British organizations are presented. The main aim of the surveys was to examine a wide range of HRM policies and practices in a cross-national comparative context. The surveys were run in six industries in the manufacturing sector. The study controlled for a number of variables such as size of the organization, product, industry sector and personnel participation. Influence of a number of contingent variables (such as age, size, nature and life-cycle stage of the organization, presence of unions and human resource strategies) on HRM policies and practices is analysed. The study finds significant differences in recruitment, compensation, training and development and employee communication practices between India and Britain.

Re-engineering construction communication in distance management framework

In an exploding and fluctuating construction market, managers are facing a challenge, which is how to manage business on a wider scale and to utilize modern developments in information technology to promote productivity. The extraordinary development of telecommunications and computer technology makes it possible for people to plan, lead, control, organize and manage projects from a distance without the need to be on site on a daily basis. A modern management known as distance management (DM) or remote management is emerging. Physical distance no longer determines the boundary of management since managers can now operate projects through virtual teams that organize manpower, material and production without face-to-face communication. What organization prototype could overcome psychological and physical barriers to reengineer a successful project through information technology? What criteria distinguishes the adapted way of communication of individual activities in a teamwork and assist the integration of an efficient and effective communication between face-to-face and a physical distance? The entire methodology has been explained through a case application on refuse incineration plant projects in Taiwan.

Strategic planning and performance:extending the debate

This article extends the debate regarding the relationship between strategic planning and performance. It addresses criticism of previous empirical studies that have largely investigated direct and bi-variate relationships, producing equivocal results. The current study investigates the mediating effects of four types of flexibility on the strategic planning and performance relationship. Flexibility is defined as the extent to which new and alternative decisions are generated and considered in strategic planning, allowing for positive organizational change and adaptation to environmental turbulence. Through investigating simultaneous equations in a structural equation model, we find that two types of flexibility mediate the relationship between strategic planning and financial performance, while the other two types mediate the relationship between strategic planning and non-financial performance. The results are new empirical insights that have not been previously reported.

International handbook of organizational teamwork and cooperative working

In today's fast changing, hyper–competitive environment, teamwork and co–operative working enhance the organisation's adaptive capability. The team, rather than the individual, is increasingly seen as the building block of organisations and a key source of competitive advantage. The International Handbook of Organisational Teamwork and Co–operative Working provides a clear focus on the psychological and social processes that can stimulate successful cooperation and teamwork. Michael West, Dean Tjosvold and Ken Smith have brought together the world's leading authorities from a range of social science disciplines to provide a contemporary review of established and emerging perspectives. Throughout the book, processes that both facilitate and obstruct successful cooperation and teamwork are detailed, alongside guidance on best practice and methodology. The challenging and alternative perspectives presented will inform future research and practice. The result is a systematic and comprehensive synthesis of knowledge from a range of disciplines that will prove invaluable to professionals, researchers and students alike. * A systematic and coherent framework which organizes and structures the knowledge in this field * An outstanding collection of authoritative "high profile" authors * Challenging, alternative perspectives that will stimulate and enlighten future research and practice * Selective, updated bibliographies of key literatures support every chapter, a valuable resource for students, trainers and practitioners

A study of magnetic non-linearity and finite length effects in solid iron subjected to a travelling MMF wave

This thesis describes an experimental and analytic study of the effects of magnetic non-linearity and finite length on the loss and field distribution in solid iron due to a travelling mmf wave. In the first half of the thesis, a two-dimensional solution is developed which accounts for the effects of both magnetic non-linearity and eddy-current reaction; this solution is extended, in the second half, to a three-dimensional model. In the two-dimensional solution, new equations for loss and flux/pole are given; these equations contain the primary excitation, the machine parameters and factors describing the shape of the normal B-H curve. The solution applies to machines of any air-gap length. The conditions for maximum loss are defined, and generalised torque/frequency curves are obtained. A relationship between the peripheral component of magnetic field on the surface of the iron and the primary excitation is given. The effects of magnetic non-linearity and finite length are combined analytically by introducing an equivalent constant permeability into a linear three-dimensional analysis. The equivalent constant permeability is defined from the non-linear solution for the two-dimensional magnetic field at the axial centre of the machine to avoid iterative solutions. In the linear three-dimensional analysis, the primary excitation in the passive end-regions of the machine is set equal to zero and the secondary end faces are developed onto the air-gap surface. The analyses, and the assumptions on which they are based, were verified on an experimental machine which consists of a three-phase rotor and alternative solid iron stators, one with copper end rings, and one without copper end rings j the main dimensions of the two stators are identical. Measurements of torque, flux /pole, surface current density and radial power flow were obtained for both stators over a range of frequencies and excitations. Comparison of the measurements on the two stators enabled the individual effects of finite length and saturation to be identified, and the definition of constant equivalent permeability to be verified. The penetration of the peripheral flux into the stator with copper end rings was measured and compared with theoretical penetration curves. Agreement between measured and theoretical results was generally good.

Identifying criteria for the assessment of pharmacy students' communication skills with patients

Objectives To identify criteria by which patients can assess the communication skills of pharmacy students. Method Potential assessment criteria were generated from 2 main sources: a literature review and a focus group discussion. A modified two-round Delphi survey was subsequently conducted with 35 professionals who were actively involved in teaching and assessing communication skills of pharmacy students to determine the importance and reliability of each criterion. Results Consensus ratings identified 7 criteria that were important measures of pharmacy students' communication skills and could be reliably assessed by patients. Conclusions A modified two-round Delphi consultation survey successfully identified criteria that can be used by patients to assess the communication skills of pharmacy undergraduates. Future work will examine the feasibility of using patients as assessors of communication skills of pharmacy students, preregistration pharmacists, and qualified pharmacists.
