The global obesity pandemic has been well-documented and widely discussed by the public, the media, health officials, the food industry and academic researchers. While the problem is widely recognised, the potential solutions are far less clear. There is only limited evidence to guide decisions as to how best to manage obesity in individuals and in populations. While widely viewed as a clinical and public health problem in developed countries, it is now clear that many developing countries also have to grapple with this problem or face the crippling healthcare costs resulting from obesity-related morbidity. There is also abundant evidence that obesity is socio-economically distributed. In developed countries persons of lower socio-economic position are more likely to be affected, while in developing countries, it is often those of higher socio-economic position who are overweight or obese. The aim of this paper is to briefly review the evidence that links socio-economic position and obesity, to discuss what is known about underlying mechanisms, and to consider the role of social, physical, policy and cultural environments in explaining the relationships between socio-economic position and obesity. We introduce the concept of ‘resilience’ as a potential theoretical construct to guide research efforts aimed at understanding how some socio-economically disadvantaged individuals manage to avoid obesity. We conclude by considering an agenda to guide future research and programs focused on understanding and reducing obesity among those of low socio-economic position.

Objective: This study employed a multilevel design to test the contribution of individual, social and environmental factors to mediating socio-economic status (SES) inequalities in fruit and vegetable consumption among women. Design: A cross-sectional survey was linked with objective environmental data. Setting: A community sample involving 45 neighbourhoods. Subjects: In total, 1347 women from 45 neighbourhoods provided survey data on their SES (highest education level), nutrition knowledge, health considerations related to food purchasing, and social support for healthy eating. These data were linked with objective environmental data on the density of supermarkets and fruit and vegetable outlets in local neighbourhoods. Results: Multilevel modelling showed that individual and social factors partly mediated, but did not completely explain, SES variations in fruit and vegetable consumption. Store density did not mediate the relationship of SES with fruit or vegetable consumption. Conclusions: Nutrition promotion interventions should focus on enhancing nutrition knowledge and health considerations underlying food purchasing in order to promote healthy eating, particularly among those who are socio-economically disadvantaged. Further investigation is required to identify additional potential mediators of SES–diet relationships, particularly at the environmental level.

Gift Wrapping is part of a valued ritual of giving that is important culturally, socially and economically. Consumer researchers have studied the process and meanings of gift giving with little consideration for the gift wrapping. The way a gift is wrapped involves a complex range of decisions and meanings. Building on existing literature we propose a model based on existing models of the gift giving process. Our model is based on value, context, relationship, and appropriateness of consumption as perceived by the donor.

This paper reports the findings of an investigation into the ethical outlook of micro business operators. The study was conducted in Australia and is the first such examination of ethical perspectives in this segment of the business population. Micro business is internationally recognizable, economically significant, and strongly entrepreneurial, and it has a high level of control over the values it enacts. The study indicates that ethical considerations are important to Australian micro business operators. While no one single ethical perspective was dominant, nonreligious beliefs and principles were found to be the most important determinant of their ethical values. Some variation was discovered in operator attitudes based on age, gender, and education.

As construction companies continue to explore foreign construction markets, various international construction projects are being undertaken in all corners of the world. In an international construction project with many unique and complicated characteristics, human resource management can play a significant role in promoting the efficient use of complex human resources. The aim of this paper is to establish a valid foundation for further research on measuring the impact of human resource management economically for international construction projects. The paper examines human resource management literature and identifies the application of the related management techniques to the construction industry. In addition, the paper uses the literature analysis to describe the nature of human resource management with particular reference to international construction projects. In particular, the research described in this paper identifies economic performance factors in the implementation human resource management in international construction projects. This paper also identifies the social effects of human resource management practices.

This chapter is concerned with how Tanzania has been socially and economically affected by post-colonialism at a policy level as well as at an ordinary (public) level during the IT policy development process in the country. An IT policy according to Corbitt (1999:309) "is a reflection of the society in which it is formed and is socially constructed within the ideologies which frame that society." Corbitt (1999:312) goes on to describe the implementation phase of the policy: Policy is implemented in an environment influenced by ideologies which spawn values and beliefs, some of which are known, recognized and obvious to the actors involved, whilst other influences are not recognized, nor obvious.This chapter examines the post-colonial influence, which comprises both directly and indirectly, observed implications within the IT policy development process in Tanzania. The discussion focuses on challenges which face decision and policy-makers in the country. The chapter also proposes an IT policy model which might be developed or designed using a different approach from the traditional policy-making model.

Nature of bribery contrasted with the practice of networking - whether the different moral and legal treatment of the practices is based on principle or simply cultural preference - bribery and the form of networking known as expenditure networking both have the affect of distorting the proper functioning of the market economy by encouraging business decisions to be made on the basis of economically irrelevant considerations - the objective of both practices is to gain a market advantage by providing a 'sweetener' to a person responsible for delegating the provision of goods and services - expenditure networking does have the positive side effect of drawing people together in a social setting.

Cold bulk metal forming has made large-scale production of small complex solid parts economically feasible. Tooling used in metal forming poses many uncertainties in the preliminary cost estimation and production process and continual tool replacement and maintenance dramatically reduces productivity and raises manufacturing cost. In order to tackle this, an on-line tool condition monitoring system using artificial neural network (ANN) to integrate information from multiple sensors for forging process has been developed. Together with the force, acoustic emission signals and process conditions, information developed from theoretical models is integrated into the ANN tool monitoring system to predict tool life and provide the maintenance schedule.

The role of commodity prices and subsidies on the adoption of soil conservation has been widely debated yet is poorly understood. One reason for this is the complex nature of the relationship between soil loss and yield damage. This paper examines the effects of price and subsidy policy on adoption of soil conservation measures in tea lands in Sri Lanka. The soil conservation technologies considered are lateral drains, stone terraces and Sloping Agricultural Land Technique (SALT). The study uses a non-linear yield damage function to estimate tea yield loss due to soil erosion. The yield function is then used in conjunction with a simple analytical model to examine the effects of changes in price and subsidies
on the incentives to adopt various soil conservation technologies. When there is a yield increment with soil conservation, increases in both prices and subsidies are found to make soil conservation economically attractive.

It is often argued that economically marginalized young women occupy a school and post-school underclass, and that this underclass has a particular culture associated with it. Such views provoke a profound ambivalence in many of those who work with such young people. On the one hand, they are anxious to acknowledge the culture of the communities to which marginalized young women belong. On the other hand, they wish to avoid the pernicious implications of underclass theories that suggest disadvantage is the result of the culture and values of marginalized social groupings. This paper offers an overview and feminist critique of the structuralist and cultural or behaviourist strands of underclass theory. It focuses particularly on the work of Charles Murray, a major proponent of the culturalist perspective and the representation of the single mother in this discourse. It then considers how a less punitive theorization of marginalized cultures might be achieved by drawing on and adapting concepts from Pierre Bourdieu's sociology. The paper reflects on how such ideas might serve as a way of exploring how gender impacts on the forms of cultural capital available to young women in difficult economic circumstances.

How do teachers make sense of ethnic and classed differences? Frequently students from non-mainstream cultures and of lower socio-economic status are constructed in the literature and through practice as ‘deficit’ and consequently become marginalised. A range of short-term, ‘quick fix’ policy and curriculum approaches have aimed to address the ‘problems’ of those ‘othered’ from the mainstream due to their perceived difference. These have had little effect on improving educational results for students of specific ethnic and/or class backgrounds whose outcomes remain below the national average.

Poststructural theories offer opportunities to think about how teachers are positioned within discourses of identity. Our research (and others’) suggests the need for teachers to interrogate their assumptions about class and culture and how these are played out in their pedagogical relationships with students.

In this paper we report on a small research project that investigates the professional practices and personal beliefs of teachers. Empirical data from this study will build knowledge about how difference is constructed and diversity is ‘taken up’ by teachers as they engage with secondary students who have Language Backgrounds Other Than English and who are economically disadvantaged.

The use of electricity in buildings constitutes around 16% of Singapore's energy demand. In view of the fact that Singapore is an urban city with no rural base, which depends heavily on air-conditioning to cool its buildings all year round, the survival as a nation depends on its ability to excel economically. To incorporate energy efficiency measures is one of the key missions to ensure that the economy is sustainable. The recently launched building energy efficiency labelling programme is such an initiative. Buildings whose energy performance are among the nation's top 25% and maintain a healthy and productive indoor environment as well as uphold a minimum performance for different systems can qualify to attain the Energy Smart Office Label. Detailed methodologies of the labelling process as well as the performance standards are elaborated. The main strengths of this system namely a rigorous benchmarking database and an independent audit conducted by a private accredited Energy Service Company (ESCO) are highlighted. A few buildings were awarded the Energy Smart Office Label during the launching of the programme conducted in December 2005. The labeling of other types of buildings like hotels, schools, hospitals, etc. is ongoing.

This article reports on a pilot study that investigated the beliefs, values, and pedagogies of experienced high school teachers who worked with student populations of non-English speaking and economically disadvantaged immigrants or refugees in Australia. Qualitative research methods, including focus groups and in-depth individual interviews with teachers, produced data that were examined using Critical Discourse Analysis. Close reading of the teachers' comments suggests that there are a number of key discourses that teachers use to make sense of differences among culturally diverse and economically disadvantaged groups of students. Specifically, teachers distinguish between cultural groups on the basis of students' life experiences prior to arrival in Australia; students' collective and individual educational experiences; and the different social class positioning of students within the same ethnic group. In their comments, teachers at times categorised students in generalised and stereotypical ways but also were able to critique and reflect on their personal assumptions. An analysis of the teachers' reflections provides insights into how they made sense of “diversity” and how, as teachers, they try to work productively with ethnically diverse and economically disadvantaged students.

Objectives: Small businesses are estimated to contribute a significant proportion of global pollution, yet there is little empirical evidence to support this claim. The main aim of this research was to conduct an exploratory analysis of small business’s environmental impact in terms of waste, water and energy.

Prior work: Due to the negative impact small businesses are reported to have on the environment, their disengagement in environmental management practices has caused international concern. Much of the literature has concentrated on identifying the barriers and drivers of small business engagement. Little empirical work being conducted on the actual impact of they have on the environment or on the influence of the local context on their environmental practices.

Approach: A survey was developed and distributed to 466 small businesses within two light industrial areas in Perth Western Australia, which achieved a response rate of 87%. This survey will be replicated after a 12 month intervention is conducted. The two light industrial areas were selected as their Local Government Authorities are looking for businesses within their boundaries to improve their environmental performance.

Results: Initial results suggest that the small businesses do have a considerable impact on the environment in terms of waste disposal. Moreover, their environmental management practices concerning waste, energy and water were found to differ depending on the local contexts in which the small businesses operate.

Implications:
As small businesses are both economically and socially important to all major industrialised nations, empirical research that provides evidence of their impact on the environment is critical. The implication here is that if the context in which these businesses operate influences the practices employed, developing strategies that acknowledge the influence and consequences of context may be more effective than those currently available. Differences identified within practices suggest that greater awareness and education is needed on water management than energy or waste, as this is the area where small business owner-managers have shown they have less knowledge and/or active engagement.

Value: This research is valuable in three ways. First, it adds to the knowledge of small business impact on the environment. Second, it identifies that context may be a factor that needs to be considered when developing strategies to engage small businesses in environmental management. Finally, it shows that the environmental management of water is the least well established environmental priority of small businesses at this time.
