Is the risk of illness through consuming vegetables irrigated with reclaimed wastewater different for different population groups?

The use of reclaimed wastewater for irrigation of horticultural crops is commonplace in many parts of the world and is likely to increase. Concerns about risks to human health arising from such practice, especially with respect to infection with microbial pathogens, are common. Several factors need to be considered when attempting to quantify the risk posed to a population, such as the concentration of pathogens in the source water, water treatment efficiency, the volume of water coming into contact with the crop, and the die-off rate of pathogens in the environment. Another factor, which has received relatively less attention, is the amount of food consumed. Plainly, higher consumption rates place one at greater risk of becoming infected. The amount of vegetables consumed is known to vary among ethic groups. We use Quantitative Microbial Risk Assessment Modelling (QMRA) to see if certain ethnic groups are exposed to higher risks by virtue of their consumption behaviour. The results suggest that despite the disparities in consumption rates by different ethnic groups they generally all faced comparable levels of risks. We conclude by suggesting that QMRA should be used to assess the relative levels of risk faced by groups based on divisions other than ethnicity, such as those with compromised immune systems.

Diabetes and ethnic minorities

The global prevalence of diabetes for all age groups is estimated to be 2.8%. Type 2 diabetes accounts for at least 90% of diabetes worldwide. Diabetes incidence, prevalence, and disease progression varies by ethnic group. This review highlights unique aspects of the risk of developing diabetes, its overwhelming vascular complications, and their management mainly using data among South Asians and African-Caribbeans in the UK but also using non-UK data. It is concluded that although the origin of the ethnic differences in incidence need further clarification, many factors should be amenable to prevention and treatment in all ethnic groups worldwide.

The influence of collectivism in society and its implications for research on information systems and national culture

This paper argues that the nature of IS research that deals with indigenous culture must be informed as much by context as it is by culture models, which has been the focus of such research in the past. This is considered important because it better reflects the meaning of the data collected for the researcher. To appreciate the importance of context this papers also argues that research subjects from designated individualist societies will inform the researcher in different ways from those subjects located in collectivist societies. To illustrate the practical implications of this argument the paper reports three separate case studies in IS research where the researchers reflect on the impact that a collectivist view has had on the research findings. The paper suggests that (1) similar ethnicity and appearance are significant in gaining the trust of subjects in a collectivist society; that is the researcher is part of the in-group as they belong to the same culture or ethnic group; that (2) who introduced the researcher to the subject is significant in that trust is best reflected when a member of the group/collective plays an important role in the research process itself; and that (3) an ability to (a) communicate in the natural language and (b) understand the implicit body language and (c) cultural codes is important in gaining significant and more meaningful research outcomes. This is enabled via the implicit meanings embedded in members of the collectivist society.

Arts marketing challenges in multicultural societies

With an increasingly diverse, multicultural society in many countries, it is timely to look more closely at the current literature on arts marketing, ethnic identity and segmentation issues. The growth of diverse, multicultural societies in many countries warrants a closer examination of arts marketing and the use of ethnicity as a basis for segmentation, as these issues have implications for attracting and retaining arts audiences and other consumers of arts related activities. Researchers in the arts industry have stressed the importance of understanding the fundamentals of audience development and the ability to focus on satisfying the needs and wants of their audiences. The focus on marketing activities comes at a time when there is greater pressure on arts organisations to move beyond their traditional role as subsidized non-profit organisations in order to become more self-supporting. Internationally, audience development in the arts industry has focused on segmentation dimensions such as youth, mature aged individuals, geographic location (rural), individuals with disabilities, low income earners, and individuals with culturally diverse backgrounds. Most of these potential segments are under represented in the population of arts consumers in Australia, the United Kingdom, Singapore, and North America. Of those dimensions, segmentation of arts markets by cultural differences such as ethnic identity appears to be a somewhat under researched area. Hofstede's (1980) model of national cultural differences continues to be widely used as a basis for strategic and marketing decisions in international business. However, the cultural characteristics attributed to individuals in their country of birth are likely to change through immigration to another country. In this situation, the ability to predict the consumption behaviour of various ethnic groups is complicated by acculturation processes in which arrivals attempt to adapt to their new environment. Over time, this process has resulted in the emergence of bicultural individuals who are able to switch, at will, between their ethnic identity and an identity aligned with their host country, or a combination of both at any time. Ethnic identity and affiliation with ethnic groups can also change over time, suggesting challenges for arts marketing approaches, and the application of market segmentation theory in particular.

Musical arts education in Africa : differentiation, integration and disassociation

By discussing the future challenges to musical arts education in Africa in which local cultural practices are valued, the differences of those historically marginalised by virtue of gender, race, ethnicity, and class, are celebrated. In Africa, musical arts education and culture are regarded as an integral part of our life, which not only embraces the spiritual, material and intellectual aspects of our society, but also contributes greatly toward our emotional development. This affirms the integrity and importance of various forms of 'Art' including literature, technology, design, dance, drama, music, visual art, media and communication.

This paper will discuss the future of African musical arts education programmes through the dynamic cycle of differentiation, integration and disassociation. The authors will consider the concept of ‘differentiation’, ‘integration’ and ‘disassociation’ within musical arts practice. An analysis of selected international arts education programmes provides a globally differentiated perspective through a discipline-based approach. In the African context, arts education programmes are located within an integrated approach. The structure of a Music Action Research Team (MAT cell) in Southern African Developing Community (SADC) countries will be highlighted as a means to address disassociation through the active engagement of professional development programmes offered by the Centre for Indigenous African Instrumental Music and Dance (CIIMDA).

Technological disadvantage of the digital age

Debates continue about the relative benefits, costs and risks of the diffusion of computer-based technologies throughout society and schooling. One area that has received considerable attention is gender equity. Early work on gender and computers focused on differences between male and female access and use (e.g. Huff, Fleming & Cooper, 1992; Kirkman, 1993; Morritt, 1997; Nelson & Cooper, 1997; Sofia, 1993), with concerns focused on the potential for girls to be disadvantaged. In some respects, it is arguable that problems of gender equity in schools with respect to computers have been overcome. For example, in a small study I conducted in two New Zealand senior primary classrooms in 2003, I found that both boys and girls were motivated to use computers and appeared to have equal opportunities to access computers in the classroom. The students in my study expressed a belief in the importance of using computers, and this belief can also be discerned from educational policy and media coverage.
In this paper I argue that, although gender by itself no longer appears to be a source of disadvantage in terms of access to and use of computers in schools, many questions about technology, schooling and power relations still remain unanswered. I present two alternative viewpoints on the new digital age. First, I explore Melanie Stewart Millar’s (1998) analysis of digital discourse as one which reproduces the power of white, middle-class, educated, well-paid males, and excludes anything else it considers ‘Other’. Second, I review arguments that the digital age has provided sites for the transcendence of traditional hierarchies and inequalities (e.g. Spender, 1995). I conclude that, despite the discrepancies between these two viewpoints, both concur that technological disadvantage will exacerbate any existing inequality that might result from intersections of identity categories, such as, gender, ethnicity, age, and socio-economic status.

Where else have you been? The effects of diaspora consciousness and transcultural mixtures on ethnic identity

In social science research, the demographic categories of ethnicity are linked to what the census bureau considers as a person’s ethnic heritage. However, these categories are based on the societal assumption that members of a given category share the same characteristics and life experiences, even though the heterogeneity between members within a category may be as diverse as between categories. The paper examines the 15 interview subjects of a research study drawn from 10 minority migrant groups, where seven of them indicated significant transcultural experiences before migrating to Australia. It argues that their lived experiences and subjectivity vary from others who migrated directly from their native countries. The formers’ diaspora consciousness and transcultural mixtures may introduce an artifact to a research study’s design, affecting the validity of the data collected. The paper examines other situations where this anomaly can occur and proposes precautions
to minimize its negative effects.

Schooling, normalisation, and gendered bodies : adolescent boys' and girls' experiences of gender and schooling

Dominant discourses construct boys and girls as two homogenous groups in need of particular, and uniform, kinds of interventions (Martino, Mills, & Lingard, 2005, Mills, Martino, & Lingard, 2004; Jones & Myhill, 2004). The boys and girls themselves, however, tell a much more complex story and challenge us to consider very different implications for addressing gender conformity and, more broadly, diversity in schools. In this chapter, the voices of students are used as text to explicate, first, how issues of gender, sexuality, social class, ethnicity and the body are implicated and interweave in girls’ and boys’ social experiences of schooling; and second, what the implications of this interweaving might be for addressing diversity in schools (Connell, 1995; 2002; Martino, 1999, 2000; Pallotta-Chiarolli, 1995, 1998, 2000, 2005). This work draws on and elaborates further our previous published research that investigates issues of gender and schooling. It locates such research within the broader international context of studies conducted into issues of gender and schooling that document student perspectives and voice (Fine & Weiss, 2003; Ferguson, 2001; Renold, 2003; Mac an Ghaill, 1994; Lees, 1993; Ornstein, 1995; Thorne, 1993; Mills, 2001; Hey, 1997; Willis,1977; Walker, 1988). The use of student voice as text is considered within that broader context and highlights the significance of gender regimes and power relations in students’ lives at school (Martino & Pallotta-Chiarolli, 2005; 2003; 2002; 2001; Pallotta-Chiarolli, 1998). We illustrate the extent to which the risky business of ‘fitting in’ involves negotiations around normative and transgressive masculinities and femininities and how such practices intersect with sexuality, race/culture, class, and geographical location (see James, 2003; Kumashiro, 2002).

Ischaemic heart disease and Australian immigrants: the influence of birthplace and language skills on treatment and use of health services

Admission rates for ischaemic heart disease (IHD), and the use of invasive cardiovascular procedures, separation mode and length of stay (LOS) were compared between Australians from non-English speaking background (NESB; n=8627) and English speaking background (ESB; n=13162) aged 20 years and over admitted to Victorian urban public hospitals. The study covered the period from 1993 to 1998. It was found that, compared with their ESB counterparts, the incidence of admission for acute myocardial infarction was significantly higher for NESB men and women before and after controlling for confounding factors. The age-adjusted ratios for NESB women compared with their ESB counterparts ranged from 1.23 to 1.89 for cardiac catheterisation, from 0.23 to 0.27 for percutaneous transluminal coronary angioplasty (PTCA), and from 1.04 to 1.80 for coronary artery bypass grafting (CABG).
Procedure rates were comparable in men for cardiac catheterisation and CABG but higher for PTA rates in NESB men (OR: 1.29, 95%CI: 1.11-1.50) than their ESB counterparts. Both NESB men (β=0.04, 95%CI: 0.01-0.07) and women (β=0.03, 95%CI: 0.02-0.08) experienced significantly longer hospital stays than their ESB counterparts. These findings indicate there may be systematic differences in patients’ treatment and service utilisation in Victorian public hospitals. The extent to which physicians’ bias and
patients’ choice could explain these differences requires further investigation.

Parent abuse: a review

A recent focus of research and clinical practice has been on the issue of abuse of parents by their children (parent abuse). This paper reviews the literature on this phenomenon. While parent abuse falls under the umbrella of family violence, it appears to be qualitatively different from other forms of intra-family abuse. Research has primarily focused on prevalence rates and the characteristics of perpetrators and victims. While various factors such as gender, age, emotional attachment to parents, race/ethnicity, socioeconomic status, family stress and parenting style and structure have been associated with parent abuse, findings are equivocal. Etiological models are general and untested, and treatment approaches lack empirical support. It is concluded that more rigorous and extensive research is required in order to provide a deeper understanding of this complex issue, and to inform treatment approaches.

Accommodating culture and cultural diversity in online teaching

The term 'culture' has been in common use for a long time. However there is no universally accepted definition and hence it is important to define clearly what culture means in a particular research context. The research reported here is part of a project undertaken at a large Australian university in late 2005. The overall aim of the project was to identify the characteristics of culture and cultural diversity, and to consider how these manifested themselves when teaching and learning in an online environment. The article reports on particular outcomes from the second stage of the project. This involved conducting focus groups with experienced academics and educational developers of online units. The aim was to gain an understanding of culture and cultural difference in the online environment and to consider what strategies were effective in teaching a culturally diverse cohort of online students. The findings from the focus group sessions were benchmarked with other external faculty. The cultural factors of ethnicity and language, attitudes to educational learning, education and prior learning, learning styles and socio-economic background were well supported by the external faculty. However the factors of religion and gender were not supported. Practices for accommodating such cultural differences amongst students within the online class are presented.

Associations of children's perceived neighborhood environments with walking and physical activity

Purpose. To examine associations between children's perceptions of the neighborhood environment and walking and physical activity.
Design. Cross-sectional study of a school-based sample.
Setting. Elementary schools in Melbourne, Australia.
Subjects. 280 children aged 10 years (response rate 78%).
Measures. A self-report survey assessed children's perceptions of the neighborhood physical and social environments and their weekly walking frequency. Physical activity was also objectively measured using accelerometers.
Results. Multiple linear regression analyses showed a positive association between walking frequency and the number of accessible destinations in the neighborhood among boys; having a neighborhood that was easy to walk/cycle around and perceiving lots of graffiti were positively associated with walking frequency among girls. Perceiving lots of litter and rubbish was positively associated with boys' overall physical activity, but no environmental variables were associated with girls' overall physical activity.
Conclusion. Several different environmental factors were associated with walking and physical activity. Perceptions of the neighborhood environment were more strongly associated with girls' walking than with objectively-measured physical activity. Future studies should confirm these findings using objective measures and prospective study designs.

Overseas Chinese as expatriate managers in China: is their recruitment a solution to cross-cultural management problems for multinationals operating in China?

This paper examines the issue of diversity in Chinese identity and how it impacts on the operations of multinationals in China who recruit Overseas Chinese to handle cross-cultural issues. China’s rapid economic development and entry into the World Trade Organization in 2001 made her a formidable player in the global economy and direct foreign investment surged. Yet it is acknowledged that for the foreign investor in China, cross-cultural issues create difficulty at every level, from the interpersonal level relating to communication and negotiation, to the organizational level relating to decision making, human resource management practices, corporate legal institutions and liaison with government institutions. Western multinationals have considered the advantages of posting Overseas Chinese from Southeast Asian countries, Taiwan and Hong Kong to their China operations as a solution to cross-cultural management issues. But has this policy been successful? In terms of language expertise this would seem to be a good strategy, yet organizational case material contradicts this in reality. Overseas Chinese, while sharing some elements of Chinese culture with mainland Chinese, the Confucian heritage and other aspects such as language and diet, nevertheless have different world views and values and behave differently from mainland Chinese in areas critical to business management. As a survival strategy, Overseas Chinese have often developed dual identities which operate simultaneously. For political and historical reasons, many of them have had to adapt to the local culture of their country of citizenship or even hide their own ethnicity in order to survive. On the other hand, the mainland Chinese are different in that their behaviour has only had to be Chinese, but overlaid with this has been the experience of participating in a communist political environment for decades, which has left its mark on mainland Chinese culture. On the basis of their different historical experiences, in the current business environment in China, cultural confusion, difficulty and conflict may occur for the Overseas Chinese.

This paper focuses attention on the subtle cultural differences between the Overseas Chinese and mainland Chinese in an organizational context. This problem has yet to be researched in depth within international business and international management studies. It provides evidence that Overseas Chinese are not often favoured by the local Chinese. It gives insights on how to manage the local Chinese for foreign multinationals operating in China.

Understanding women's breast screening behaviour: a study carried out in South East London, with women aged 50-64 years

Objective To understand low uptake of breast cancer screening through exploring the personal reasoning underlying women's attendance or non-attendance, and identifying differences between those who attend and those who decline.

Design Cross-sectional survey.

Setting Community and home environments of women eligible for breast screening aged 50—64 years, living in South East London. Method Structured, self-completed or assisted-completion questionnaires.

Results The decision to attend or decline screening is rational and personally justifiable, engaging factors linked to emotions and attitude. Attitudes about breast screening and perceived personal importance of breast screening are the strongest predictors of attendance and non-attendance. There are differences between ethnic groups in perceptions of breast screening. Regular attendance at screening is associated with ethnicity, although consistent avoidance of mammography is not. Inconvenience is an important factor in missing appointments, and tends to be prolonged rather than specific to the time or day of the pre-booked invitation. GP and health worker advice are good persuaders towards attendance. Pain and anxiety during mammography are notable dissuaders against re-attending.

Conclusion Appropriate service provision requires consideration of local factors, as well as the medical needs of the population eligible for breast screening. Lay perceptions of potential personal costs of attending or not attending breast screening are important for guiding health promotion. Information providers should consider the language needs of a culturally and educationally mixed community. Health care professionals are well placed to encourage uptake of breast screening through disseminating information that promotes attendance, both within and outside the breast screening service.
