Contingent on context? Social work and the state in Australia, Britain, and the USA

The notion that social work is an international profession, operating with generally similar goals, methodologies, and common values is considered critically. Examining the political and social contexts of three countries with liberal democratic governments-Australia, Britain and the United States-the role of social work within the welfare processes of each country is compared. While social work as an identifiable professional activity shares some features, it is argued that the idea of its having a core essence needs to be tempered with a realistic assessment of the importance of contextually created difference. Recent and rapid developments in the institutional context, such as those experienced in these three countries, further underscore the limited utility of the notion of a common professional project.

The role of gender in the construction and evaluation of feedback effectiveness

This study investigated factors that influence managers’ conceptions and subordinates’ perceptions of effective feedback. A social rules perspective was used to operationalize male and female managers’ conceptions of effective negative feedback. In the first study, 68 male and female managers identified their optimal strategies for providing feedback to subordinates. Male and female managers endorsed different goals and tactics for giving negative feedback, particularly in terms of levels of participation and directness. In the second study, 116 male and female subordinates evaluated the comparative effectiveness and difficulty of these and other standard approaches to feedback. The female manager strategy was evaluated by both men and women as generally more task and relationship effective but not more difficult to enact.

Comic relief: Subversion and catharsis in organizational comedic theatre

There has been a growth of interest in the role of humour in organizations from both practitioner and academic perspectives. Various claims for the functionality of humour have been made, ranging from stress reduction to helping form and cement corporate cultures. Latching on to these presumed benefits, businesses and consultants have begun to employ humour and comedy in a direct and explicit manner. However, there is a counterpoint, which suggests that humour cannot always be managed and in fact has subversive qualities. This article addresses the issue of the subversive potential of comedy in organizational contexts. It draws illustratively on the case of a successful corporate comedian to do so. The article argues, through an analysis of the case, the history and philosophy of comedy, and theories of the comedic, that while comedy has inherent subversive potential, it most often is contained. Indeed, it suggests that comedy works by intruding as a potential threat to mundane reality, but offers comic relief when it is apparent that the threat will not be actualized and the status quo ante prevails. Implications for using corporate comedy are drawn..

Identity, difference, and the dilemmas of inter-Korean relations: Insights from northern defectors and the German precedent

Questions of identity have become increasingly central to the study of foreign policy and security, particularly in constructivist debates. But very few of the resulting insights have been applied to the Korean situation, where discussions about security and inter-Korean relations remain dominated by strategic and geopolitical issues. The main task of this article is to address this shortcoming by examining the experience of North Korean defectors in South Korea and the precedent of German unification. Both of these domains of inquiry reveal that identity differences between North and South persist far beyond the ideological and political structures that created them in the first place. Born out of death, fear, and longing for revenge, these identity patterns lie at the heart of Korea's security dilemmas. Unless taken seriously by scholars and decision makers, the respective tensions between identity and difference will continue to cause major political problems. (Key words: Inter-Korean relations, North Korean defectors, German unification)

Identification of two evolutionarily conserved and functional regulatory elements in intron 2 of the human BRCA1 gene

Cross-species comparative genomics is a powerful strategy for identifying functional regulatory elements within noncoding DNA. In this paper, comparative analysis of human and mouse intronic sequences in the breast cancer susceptibility gene (BRCA1) revealed two evolutionarily conserved noncoding sequences (CNS) in intron 2, 5 kb downstream of the core BRCA1 promoter. The functionality of these elements was examined using homologous-recombination-based mutagenesis of reporter gene-tagged cosmids incorporating these regions and flanking sequences from the BRCA1 locus. This showed that CNS-1 and CNS-2 have differential transcriptional regulatory activity in epithelial cell lines. Mutation of CNS-1 significantly reduced reporter gene expression to 30% of control levels. Conversely mutation of CNS-2 increased expression to 200% of control levels. Regulation is at the level of transcription and shows promoter specificity. Both elements also specifically bind nuclear proteins in vitro. These studies demonstrate that the combination of comparative genomics and functional analysis is a successful strategy to identify novel regulatory elements and provide the first direct evidence that conserved noncoding sequences in BRCA1 regulate gene expression.

Molecular motors-based micro- and nano-biocomputation devices

Protein molecular motors, which are natural nano-machines that convert the chemical energy into mechanical work for cellular motion, muscle contraction and cell division, have been integrated in the last decade in primitive nanodevices based on the motility of nano-biological objects in micro- and nano-fabricated structures. However, the motility of microorganisms powered by molecular motors has not been similarly exploited. Moreover, among the proposed devices based on molecular motors, i.e., nanosensors, nano-mechanical devices and nano-imaging devices, biocomputation devices are conspicuously missing. The present contribution discusses, based on the present state of the art nano- and micro-fabrication, the comparative advantages and disadvantages of using nano- and micro-biological objects in future computation devices.

No more free beer tomorrow? Economic policy and outcomes in Australia and New Zealand since 1984

There are no controlled experiments in macroeconomic policy, nor in systematic programs of microeconomic reform, but a comparison between New Zealand and Australia over the period since 1984 provides as close an approach to such an experiment as is ever likely to be possible. From quite similar starting points the two countries pursued liberal reform programs that differed sharply, mainly as a result of exogenous differences in constitutional structures and the personal styles of the central actors. Australia followed a more cautious, piecemeal, consensus-based approach, whereas New Zealand, in contrast, adopted a radical, rapid, 'purist' platform. The NZ reform package was generally seen by contemporary commentators as representing a 'textbook' model for best practice reform. However, Australia since 1984 has performed much better than New Zealand, whose per capita GDP growth indeed ranked at or near the bottom of the OECD. In this paper, we assess a variety of explanations for the divergences in policies and outcomes.
