'Slippage' is not a dirty word: Considering the usefulness of Giddens' notion of knowledgeability in understanding the possibilities for teacher education

The attempt to understand the relationship between messages intended and messages received has been an enduring issue in teacher education. For the past three decades researchers have made forays into understanding this enduring issue, and in the process have drawn on various explanatory frameworks, one of them being socialisation. In this paper we work with Giddens' structuration theory as well as his concept of knowledgeability as analytical frameworks for understanding the relationship between messages intended (by the teacher educator) and messages received (by the student-teachers). Our discussion is informed by the findings of a study that investigated student-teachers' interpretations of the pedagogical process of a physical education teacher education course. Data generated from conversations with, and observations of, the student-teachers indicated that there was considerable “slippage” between the teacher educator's critical pedagogy inspired intentions and what was understood by the student-teachers.

Role of culture in gambling and problem gambling

There has been a significant gap in the gambling literature regarding the role of culture in gambling and problem gambling (PG). This paper aims to reduce this gap by presenting a systematic review of the cultural variations in gambling and PG as well as a discussion of the role cultural variables can play in the initiation and maintenance of gambling in order to stimulate further research. The review shows that although studies investigating prevalence rates of gambling and PG among different cultures are not plentiful, evidence does suggest certain cultural groups are more vulnerable to begin gambling and to develop PG. Significant factors including familial/genetic, sociological, and individual factors have been found in the Western gambling literature as playing important roles in the development and maintenance of PG. These factors need to be examined now in other cultural groups so we can better understand the etiological processes involved in PG and design culturally sensitive treatments. In addition, variables, such as cultural values and beliefs, the process of acculturation, and the influence of culturally determined help-seeking behaviors need to be also examined in relation to the role they could play in the initiation of and maintenance of gambling. Understanding the contribution of cultural variables will allow us to devise better prevention and treatment options for PG. Methodological problems in this area of research are highlighted, and suggestions for future research are included. (C) 2004 Elsevier Ltd. All rights reserved.

Cross-cultural perceptions in the leadership process: Theoretical perspective on the influence of culture on self-concepts and manager worker attributions

This article examines the influence of culture on the way managers and workers perceive causes of success and failure in organizational tasks. The author argues that selfserving and actor-observer biases, as well as other attribution errors, will be moderated by culture. Specifically, managers and workers with a sociocentric self-concept from high-context cultures may be biased toward external attributions, while managers from low-context cultures with an idiocentric self-concept have a tendency to make more internal attributions. These variations in attributions have consequences that affect both managers and workers. Theoretical propositions and implications for international management practices are discussed. © 2005 Wiley Periodicals, Inc.

Control of culture environment for improved polyethylenimine-mediated transient production of recombinant monoclonal antibodies by CHO cells

In this study we describe optimization of polyethylenimine (PEI)-mediated transient production of recombinant protein by CHO cells by facile manipulation of a chemically defined culture environment to limit accumulation of nonproductive cell biomass, increase the duration of recombinant protein production from transfected plasmid DNA, and increase cell-specific production. The optimal conditions for transient transfection of suspension-adapted CHO cells using branched, 25 kDa PEI as a gene delivery vehicle were experimentally determined by production of secreted alkaline phosphatase reporter in static cultures and recombinant IgG(4) monoclonal antibody (Mab) production in agitated shake flask cultures to be a DNA concentration of 1.25 mu g 10(6) cells(-1) mL(-1) at a PEI nitrogen: DNA phosphate ratio of 20:1. These conditions represented the optimal compromise between PEI cytotoxicity and product yield with most efficient recombinant DNA utilization. Separately, both addition of recombinant insulin-like growth factor (LR3-IGF) and a reduction in culture temperature to 32 degrees C were found to increase product titer 2- and 3-fold, respectively. However, mild hypothermia and LR3-IGF acted synergistically to increase product titer 11-fold. Although increased product titer in the presence of LR3-IGF alone was solely a consequence of increased culture duration, a reduction in culture temperature post-transfection increased both the integral of viable cell concentration (IVC) and cell-specific Mab production rate. For cultures maintained at 32 degrees C in the presence of LR3-IGF, IVC and qMab were increased 4- and 2.5-fold, respectively. To further increase product yield from transfected DNA, the duration of transgene expression in cell populations maintained at 32 C in the presence of LR3-IGF was doubled by periodic resuspension of transfected cells in fresh media, leading to a 3-fold increase in accumulated Mab titer from similar to 13 to similar to 39 mg L-1. Under these conditions, Mab glycosylation at Asn297 remained essentially constant and similar to that of the same Mab produced by stably transfected GS-CHO cells. From these data we suggest that the efficiency of transient production processes (protein output per rDNA input) can be significantly improved using a combination of mild hypothermia and growth factor(s) to yield an extended activated hypothermic synthesis.

Do Australian public sector employees have the type of culture they want in the era of new public management?

New public management theory proposes that public sector organisations should be managed more like private sector organisations. It is therefore expected that public sector managers will have preferences for an organisational culture that will reflect the culture of private sector organisations, with an external rather than internal orientation. The current research investigated the idea that managers' perceptions of ideal organisational culture would be different to the bureaucratic model of culture (internally oriented), which has traditionally been associated with public sector organisations. Responses to a competing values culture inventory were received from 925 public sector employees. Results indicated that the bureaucratic model is still pervasive; however, managers prefer a culture that is more external, and less control focussed, as expected. Lower level employees expressed a desire for a culture that emphasised human relations values.

Situating Learning: (Re)examining the Notion of apprenticeship in Coach Education

The last two decades has seen a proliferation in the provision of and importance attached to coach education in many Western countries. Pivotal to many coach education programmes is the notion of apprenticeship. Increasingly, mentoring is being positioned as a possible tool for enhancing coach education and professional expertise. However, there is a paucity of empirical data on interventions in and evaluations of coach education programmes. In their recent evaluation of a coach education programme, Cassidy, Potrac & McKenzie conclude that the situated learning literature could provide coach educators with a generative platform for the (re)examination of apprenticeships and mentoring in a coach education context. This paper discusses the merits of using Situated Learning theory and the associated concept of Communities of Practice (CoP) to stimulate discussion on developing new understandings of the practices of apprenticeship and mentoring in coach education.

Mapping the notion of "terrorism" in Serbian and Croation newspapers

The September 11 terrorist attacks in the United States have reconfigured the global public debates as of how to defend a "civilized" world from the "Islamic terrorism." The U.S.-led war on terror against extremist groups also produced and triggered a particular discourse in the former Yugoslav countries. The main aim of this article is to present an example of a study that explores how media appropriate dominant global antiterrorism discourse and apply it to a local context to legitimize and justify specific ideologies and discourse. As our critical discourse analysis shows, Serbian and Croatian newspapers apply the global discourse of terrorism to their local context to excuse their nationalisms and the past military actions against the Muslims in former Yugoslav wars, and with that, they assert their belonging to an antiterrorism global discursive community. © 2006 Sage Publications.
