Because outsourcing of information systems (IS) is now widespread, it is generally assumed to be successful. It is also often assumed that outsourcing risks are easily managed. In this paper we adopt an “evidence based management” approach to first test these assumptions through a qualitative metaanalysis of academic studies into IS outsourcing outcomes. Our research reveals a shortage of reliable and valid evidence for outsourcing’s benefits, and for the level of risk involved. We then use data from a series of focus groups to explain the paradox of widespread adoption of a strategy with limited empirical support. These focus groups were interpreted through the lens of research on a
range of cognitive mechanisms and biases that are known to affect decision makers. We conclude that cognitive mechanisms that are likely to affect sourcing decisions include framing biases, cognitive dissonance, attribution error, and the “optimism”, “confirmation”, “disconfirmation” and “overconfidence” biases. Given the shortage of supporting evidence, and the potential for these biases to operate, we argue that researchers need to be more critical in their analysis of reports of the success and risks of IS outsourcing.

To identify genes involved in the central regulation of energy balance, we compared hypothalamic mRNA from lean and obese Psammomys obesus, a polygenic model of obesity, using differential display PCR. One mRNA transcript was observed to be elevated in obese, and obese diabetic, P. obesus compared with lean animals and was subsequently found to be increased 4-fold in the hypothalamus of lethal yellow agouti (Ay/a) mice, a murine model of obesity and diabetes. Intracerebroventricular infusion of antisense oligonucleotide targeted to this transcript selectively suppressed its hypothalamic mRNA levels and resulted in loss of body weight in both P. obesus and Sprague Dawley rats. Reductions in body weight were mediated by profoundly reduced food intake without a concomitant reduction in metabolic rate. Yeast two-hybrid screening, and confirmation in mammalian cells by bioluminescence resonance energy transfer analysis, demonstrated that the protein it encodes interacts with endophilins, mediators of synaptic vesicle recycling and receptor endocytosis in the brain. We therefore named this transcript Src homology 3-domain growth factor receptor-bound 2-like (endophilin) interacting protein 1 (SGIP1). SGIP1 encodes a large proline-rich protein that is expressed predominantly in the brain and is highly conserved between species. Together these data suggest that SGIP1 is an important and novel member of the group of neuronal molecules required for the regulation of energy homeostasis.

This paper develops a conceptual model of a knowledge management system that could be used to develop and implement organizational training strategies for virtual teams. An action research-based case is presented to support and illustrate the contention that action-learning methods can be effectively used to enable and tap into the knowledge generated by virtual teams. Virtual teams are an increasingly common response to changing organizational needs. However, the use of virtual teams has outpaced our understanding of their dynamics and unique characteristics. Practitioners are now offering virtual team training, but few organizations are making the effort to offer in-house training. Moreover, they are missing out on the opportunity to systematically capture the knowledge produced by virtual teams and cycle it back into virtual team training and support systems.

It is a contention of the culturalist strand of underclass theory that the growth of the underclass is not a function of social and economic change, but of features intrinsic to underclass culture. Children born into disadvantaged communities, it is argued, are socialized into the ‘deviant’ culture of their families, families typically headed by single mothers. According to the underclass thesis, daughters of such families will face a heightened risk of leaving school early and teenage pregnancy. An unanticipated correlation between claims of the underclass thesis and the cohort of mothers and daughters with whom we are working on a current project has led us to ask, ‘how do we acknowledge the culture of disadvantaged communities and their generational synergies, whilst avoiding the pernicious implications of the underclass thesis?’ To answer this question, this article assesses
the merits of bringing Bourdieu’s ideas on cultural capital together with Sarah Thornton’s concept of subcultural capital. The article concludes with two examples of how we might draw on these ideas as a way of exploring the means by which girls in difficult economic circumstances understand and pursue their school lives.

Nasogastric tubes are a medical device that can be used for a number of purposes. The process of inserting them however can be complicated. Nurses must therefore use an evidence based approach to confirm the correct position of nasogastric tubes and there are three main techniques described in the literature to do so. To date, one group of authors has published the majority of the studies on these techniques. This paper reviews their work.

A set of seven principles (the ‘Sydney Principles’) was developed by an International Obesity Taskforce (IOTF) Working Group to guide action on changing food and beverage marketing practices that target children. The aim of the present communication is to present the Sydney Principles and report on feedback received from a global consultation (November 2006 to April 2007) on the Principles.

The Principles state that actions to reduce marketing to children should: (i) support the rights of children; (ii) afford substantial protection to children; (iii) be statutory in nature; (iv) take a wide definition of commercial promotions; (v) guarantee commercial-free childhood settings; (vi) include cross-border media; and (vii) be evaluated, monitored and enforced.

The draft principles were widely disseminated and 220 responses were received from professional and scientific associations, consumer bodies, industry bodies, health professionals and others. There was virtually universal agreement on the need to have a set of principles to guide action in this contentious area of marketing to children. Apart from industry opposition to the third principle calling for a statutory approach and several comments about the implementation challenges, there was strong support for each of the Sydney Principles. Feedback on two specific issues of contention related to the age range to which restrictions should apply (most nominating age 16 or 18 years) and the types of products to be included (31 % nominating all products, 24 % all food and beverages, and 45 % energy-dense, nutrient-poor foods and beverages).

The Sydney Principles, which took a children’s rights-based approach, should be used to benchmark action to reduce marketing to children. The age definition for a child and the types of products which should have marketing restrictions may better suit a risk-based approach at this stage. The Sydney Principles should guide the formation of an International Code on Food and Beverage Marketing to Children.

Within the area of educational research that has its focus on individual differences, the concept of emotional intelligence and its study in relation to the professional lives of teachers has raised considerable interest over the past decade. This article reports on data from a new measure of emotional intelligence specifically related to situations in the teaching environment. The four underlying dimensions that are identified in this study appear to be a more relevant way of characterising emotional intelligence for those in the teaching profession than other conceptualisations of emotional intelligence. The article concludes with an examination of the contention that emotional intelligence is strongly connected to effective teaching practice

Discourse about the impact of art has been prominent in academic and arts industry discourse over the past two decades. Contention in the discourse has led to the call for new research frameworks that place the experience of the individual as central to understanding the impact of art. The authors present the background of this discourse and outline narrative inquiry as a research method that elicits individual experiences. The authors present the findings of a narrative inquiry and establish that the way individuals experience art and its impact is far broader in scope than previous research suggests.

The paper examines the relation between changing ownership structure and performance of Australian building societies. An analysis and discussion of the theories of organizational development and change is undertaken to explore the mutual building societies' motivation for change. The financial performance measures, provided by financial ratios of the major mutual building societies in Australia, are examined to assess the behaviour of building societies under different governance structures in the 1980s and 1990s. The theoretical and empirical literature has suggested that mutual deposit-taking institutions should have lov^^er profitability and higher operating expenses than their publicly listed counterparts. Accounting ratios are observed over time to investigate if governance change in mutual deposit-taking organizations accounted for any discernable differences in profitability and cost efficiency pre- and post- demutualization. The study finds support for the contention that demutualized building societies will have higher profitability and lower costs than their mutual counterparts. The study is confined to investigation of the six largest building societies that undertook the demutualization process. It could he extended to the entire building society sector. The results have implications for investors, managers and 'ovraers' of firms that retain their mutual structure, suggesting the demutualization vnû benefit these groups. There is no study that compares mutual deposit-taking institutions pre- and post-conversion in Australia.

While there has been much judicial discussion regarding the competency of Australia's continuous disclosure regime with reference to contemporaneous international standards, there has to date been limited empirical analysis of the Australian system's effectiveness in preventing selective disclosure and information leakage. This paper presents an empirical study of information content and trading behaviour around unscheduled earnings announcements - comprising of profit upgrades, profit warnings and neutral trading statements - made by ASX-listed companies during 2004. The contention is that informed trading impacts on the stock returns and trading volumes of listed entities, and hence abnormal returns or trading volumes observed prior to an announcement provide evidence of information leakage. The paper models a range of factors that potentially influence firm disclosure practices and contribute to the level information asymmetry in the market during the pre- announcement period. Previous research has investigated the influence of firm size and information content in contributing to information leakage. This study further considers the variables of firm growth, capital structure and industry group.

Objective: This study had two aims: (1) to examine pregnant women's alcohol consumption across time from prepregnancy until childbirth and (2) to explore whether prepregnancy drinking and intention to drink predict prenatal alcohol consumption while controlling for relevant demographic variables.

Methods: At 17–21 weeks, 248 pregnant women completed questions about demographics, intention to drink alcohol during the subsequent pregnancy, and retrospective measures of prepregnancy and early pregnancy consumption. After this time, calendars were sent fortnightly assessing daily alcohol consumption until birth.

Results: For women who drank both prepregnancy and postpregnancy confirmation, average fortnight alcohol consumption in the first weeks of pregnancy was lower than during prepregnancy, and consumption continued to decrease between gestational weeks 1 and 8, particularly following pregnancy confirmation, after which it remained relatively stable. When predicting whether women drank in late pregnancy, intention accounted for unique variance after controlling for income and prepregnancy drinking. For women who drank after pregnancy confirmation, prepregnancy drinking quantity significantly predicted intention to drink, which in turn predicted fortnight alcohol consumption in later pregnancy, after controlling for prepregnancy drinking and income.

Conclusions: Findings highlight the need to measure alcohol consumption at multiple time points across pregnancy, the need for educating and supporting women to reduce consumption when planning pregnancies, and the usefulness of intention to drink as a predictor of drinking during pregnancy.

This article combines the key elements of new public management theories with theories of privatisation and total quality management. The key elements identified in this review are used to establish a general model of new public management. Based on western theorising, the model is acknowledged as having a cultural bias. As a corrective, the article reviews the empirical experience of Malaysian public sector reform between 1980 and 2000, with the findings being used to identifying country-specific characteristics as a means of refining the model in a way that reflects that experience. The discussion concludes by setting out a revised model of new public management which takes account of its application in a Malaysian context. The contention is that the process of enquiry leading to this contingent model of new public management might be adapted along similar lines for the purposes of analysing the application of public sector reform in other developing countries.

Two key hypotheses emerge in the literature regarding the impact of stress on reproduction in females of any species. First, prolonged stress impairs reproduction in females. Secondly, acute stress impairs reproduction, if it occurs at a critical time during the precisely timed series of endocrine events that induce oestrus and ovulation. We reviewed studies conducted in female pigs to find support or opposition for these hypotheses in female pigs. We also considered the role of cortisol. We found confirmation that prolonged stress or the prolonged elevation of cortisol can impair reproductive processes in female pigs, but also found that there appear to be some female pigs in which reproduction is resistant to such treatments. Reproduction in female pigs appears to be resistant to acute or repeated acute stress or elevation of cortisol, even if these occur during the series of precisely timed endocrine events that induce oestrus and ovulation. Thus, we propose modified versions of the above hypotheses that are specific to female pigs. Furthermore, while cortisol may mediate the effects of prolonged stress on reproduction in female pigs, there is evidence that, in female pigs, ACTH may require the presence of the adrenal glands to impair reproduction rather than having direct effects.

Purpose – Understanding the relationship between government revenue and government expenditure is important from a policy point of view, especially for a country like Fiji, which is suffering from persistent budget deficits. The aim of this paper is to investigate the relationship between government revenue and expenditure for Fiji.

Design/methodology/approach –
The Johansen test for cointegration and Granger causality test are used to conduct the empirical analysis.

Findings – The key findings are that: government revenue and government expenditure in both the aggregate and disaggregate sense are cointegrated; in the short-run government expenditure Granger causes government revenue in an aggregate sense, departmental expenditure Granger causes aggregate revenue, and there is bidirectional causality running between government expenditure and customs duties; and in the long-run there is evidence of fiscal synchronization, implying that expenditure decisions are not made in isolation from revenue decisions.

Research limitations/implications – This fiscal synchronization has not been able curb the current account deficit in Fiji. Moreover, the confirmation of the spend-tax attitude of the government does not bode well for the level of investments and skilled human capital in Fiji as this may perpetuate tax increases in the future. Given that the Fiji Government is currently trying to rein in the escalating level of fiscal deficit, it is an opportune time for them to engage in extensive expenditure reforms.

Originality/value – The findings of this paper should allow policy makers to make informed decisions. Furthermore, the paper is different from others because apart from examining the revenue and expenditure in an aggregate sense, it also considers the different components of revenue and expenditure.

Background: Multidisciplinary team meetings (MDMs) have become an important decision-making forum in oncology. These meetings bring together expertise from each relevant field to improve continuity of care and health care outcomes for cancer patients. However there is a lack of evidence demonstrating the effectiveness of MDT meetings in improving cancer patient outcomes. The aim of this study was to explore the perceived value and potential usefulness of multidisciplinary team meetings for patients with advanced breast cancer (ABC).

Methods: ABC MDMs have been conducted since 2002 at two sites of Eastern Health, the second largest health service in Melbourne. Attendees were invited to complete a confidential questionnaire in November 2007 that comprised seven areas aimed to assess their judgment of how well the MDMs have improved patient management, including medical recommendations, psychosocial care, palliative care, community care, and team development. Average scores were calculated for improvement of each area.

Results: A total of 16 (69%) health practitioners participated in the survey, with main representation from nursing (37%), allied health (25%) and medicine (19%). Preliminary results indicate that the broad areas members reported the meeting had improved patient outcomes were in palliative care and medical management. Specific areas of perceived improvement were medical outcomes for patients; early referral to palliative care services; confirmation of diagnosis; referral to supportive care; and appropriateness of palliative care referrals. Conversely, the area that had least improved was community care, as there was no input from GPs or community services other than palliative care. Attendance by GPs and radiologists were considered important for further improving medical outcomes for patients.

Conclusions: This study demonstrates the perceived value of the MDT approach in the care of ABC patients, particularly in improving patient outcomes. The next stage of this research is to conduct a survey of ABC patient satisfaction level.
