Spatial distribution of structure infesting ant species inhabiting urban housing developments of different ages

The distribution of ant colonies within a community is often well defined, yet this distribution can change due to changing environmental conditions, resource availability, and colony growth. In this study, structure infesting ant communities were sampled for one year within three Puerto Rican housing developments of different ages. These developments represented environments in different stages of recovery after a disturbance (secondary succession). Spatial mapping was used to plot the distribution and abundance of ant communities within these developments. At the beginning of the study, the youngest housing development (1 year since construction), had the fewest number of species present (ave. 1.6 per house). The second housing development (4 years old) had a greater number of species (ave. 2.6 per house), and a greater sampling frequency (the same species collected at multiple houses) than Site 1. The oldest development (8 years old) had both the greatest number of species (ave. 2.7 per house), and sampling frequency of the three sites. In all developments, the number of species, sampling frequency, and ant biomass increased throughout the year as colonies grew and foraging ranges expanded. It was observed in all developments, that species coexistence also increased throughout the year. As colony populations increased, there was a greater occurrence of multiple species being collected at the same sample house. In the youngest development, the two most dominant species increased in numbers during the year and began to be collected from the same sample houses. Spatial diagrams documented that multiple species in the older housing developments (later stages of succession), also shared a common distribution. Even the most dominant species (S. invicta) in all three sites, did not exclude additional species from foraging within its established range.     

Somebody versus nobody: An exploration of the role of celebrity status in an election

This study examines the role celebrity status may play in potential voters’ evaluation of a political candidate presented in a newspaper article. Participants indicated greater intention to vote for a candidate who was a recognizable Hollywood actor than an unknown candidate in a political race, regardless of how substantive the political information provided about the candidate was. This suggests that familiarity with a celebrity can act as a heuristic in peripheral processing. Younger people were more likely to vote for a celebrity candidate than older voters, but how liberal or conservative participants are was not a significant factor in the decision to vote for the celebrity. Nor did participants’ need for cognition or level of political involvement predict intention to vote for the celebrity, suggesting that celebrity status is meaningful to motivated and thoughtful voters as well as those who are less motivated and informed. The possibility is raised that this could be an indication of celebrity status being used as a component of deliberate political decision-making, and future research in this direction is suggested.     

Intensity and persistence of individuals' social exclusion in Australia

We construct a measure of social exclusion that recognises its multidimensionality at the individual level, including its potential variability in intensity at a point in time and in persistence over time. We distinguish seven dimensions or domains of social exclusion: material resources; employment; education and skills; health and disability; social; community; and personal safety. For each of these seven domains, several indicators of social exclusion are produced. Our exclusion measure identifies 20 to 30 per cent of the Australian population aged 15 years and over as experiencing ‘marginal’ or worse levels of exclusion at any given point in time. However, there is considerable variation in both the extent and persistence of exclusion among the excluded. We further find that, although there are commonalities in the demographic composition of the socially excluded and the income poor, there are also some important differences. For example, persons 65 years and over represent a much smaller share of the most ‘excluded’ group than they do of the ‘poorest‘; and – adopting a household‐level measure of exclusion – children represent a larger share of the excluded than they do of the poor.     

Continuing professional development after qualification--partnerships,pitfalls and potential

Social work educators, employers and policy-makers have increasingly recognised the importance of continuing professional development. The UK social work qualification (DipSW) provides a broad base of practice skills, knowledge and values. However, increasingly complex work, frequent legislative and policy changes, research findings and challenges of working in a societal context of increasing change and diversity all contribute to the necessity of developing strategies for continuing professional development which adequately equip social workers. Such education cannot be alienated from social workers' employment context, and thus needs to remain mindful of employers' needs while concurrently maintaining academic rigour. This paper explores the development and delivery of a year-long post-qualifying training course run collaboratively between West Sussex Social and Caring Services and University College Chichester. It places some of the experiences of tutors, candidates and Training and Development Officers within the wider context of social work education, training and the delivery of social care. In exploring some of the contradictions and tensions experienced it seeks to further understand the challenge of delivering effective training in an increasingly complex and fragmented arena. Finally, it considers possible future developments, mindful of future changes in UK social work education.     

The Impact of Immigrant Status on Home Ownership in Australia

This paper examines the impact of immigrant status on home ownership in Australia. It shows that the rate of home ownership for most groups of immigrants is comparable to that of the Australian born. As expected, recently arrived immigrants have relatively low probabilities of owning their own home. These results hold for both analyses pooled across movers and non‐movers, and for analyses restricted to those, both immigrants and the native born, who moved residence in the previous five years. A decomposition of the estimated coefficients of the model of tenure choice is developed. This is shown to enhance understanding of variations in rates of home ownership across birthplace groups.     

Rethinking Marketing Programs for Emerging Markets

This article points to a fundamental inconsistency in the emerging market strategies of multinational firms. On the one hand, they seek billions of new consumers in the emerging markets of China, India, Indonesia, and Latin America—on the other, their marketing programs are scarcely adapted for these markets. The result is low market penetration, disappointing market shares and poor profitability. These multinationals are trapped by their own devices in gilded cages, serving the affluent few but ignoring the potential of the billions of new consumers that attracted them in the first place. In this article we propose that, in order to attract billions of new consumers, the marketing programs of multinationals need to be rethought from the ground up. We identify three key factors that characterize emerging markets: (1) low incomes, (2) variability in consumers and infrastructure, and (3) the relative cheapness of labor, which is often substituted for capital. We draw on numerous case studies from around the world to illustrate how to incorporate these realities into marketing programs. We conclude with a discussion of the implications of such an approach for the multinational’s core strategic assumptions.     

Six Propositions on Public Participation and Their Relevance for Risk Communication

New societal obligations for communicating risk information are emerging in a variety of contexts. This article draws upon the lengthy societal experience with citizen participation programs to identify how risk communication efforts may be effectively structured and implemented. Six major propositions address such themes as means/ends differences in expectations, the timing of the program, the role of credibility and trust, the need for technical and analytical resources, differing thresholds of public involvement, and limitations upon current understandings. Key conclusions for the design of risk communication programs are set forth.
