There has been much commentary about the re-ordering of the relations between nation state government, geographical territory, and populations in the advanced liberal democracies. This is seen as a product of: increasing demographic and cultural diversity due to legal and illegal migration; economic, cultural, and political global interdependence; footloose mobility of capital and the outsourcing of jobs to poorer countries; the growing power of international corporations and financial markets; and the growth of supra-national bodies like the European Union and The North Atlantic Free Trade Association, the World Trade Organisation, and (debatably), the UN. These developments are held to be associated with the gradual demise of the model of the increasingly secular nation state first crystallised by the Treaty of Westphalia in 1648. This conception provided a mutual, guarantee of states’ jurisdiction over territory and populations through their legitimated attempts to monopolise the use of force. Though, the relations between these states have always been asymmetrical and often challenged (Hunter 1998).

It is a challenging time to be a social scientist. Many of the concepts and categories we took for granted have been revealed as temporally and geographically specific. It is now widely accepted that the nation-state is no longer the sole container for economic, political and social processes, if indeed it ever was. This is where Kevin Stenson begins his paper. He traces the re-ordering of both state and nation, highlighting recent discussions about the unbundling and rescaling of the state and outlining how increasing ethnic and cultural diversity challenge homogeneous conceptions of the nation. In Stenson’s account these are largely empirical processes that are the basis for the important questions he raises about changing understandings of publics and social order, and their implications for the local governance of community safety. He contrasts two alternative positions; the ‘universal human rights position’ which refuses to privilege the interests of majority populations, and a more ‘communitarian and nationalistic position’ which he argues is most likely to be deployed by right wing politicians and interests groups. Drawing from extensive research in the Thames Valley region of the United Kingdom, he shows how these two understandings have both shaped the local policy response to crime and disorder.

Nosema spp. fungal gut parasites are among myriad possible explanations for contemporary increased mortality of western honey bees (Apis mellifera, hereafter honey bee) in many regions of the world. Invasive Nosema ceranae is particularly worrisome because some evidence suggests it has greater virulence than its congener N. apis. N. ceranae appears to have recently switched hosts from Asian honey bees (Apis cerana) and now has a nearly global distribution in honey bees, apparently displacing N. apis. We examined parasite reproduction and effects of N. apis, N. ceranae, and mixed Nosema infections on honey bee hosts in laboratory experiments. Both infection intensity and honey bee mortality were significantly greater for N. ceranae than for N. apis or mixed infections; mixed infection resulted in mortality similar to N. apis parasitism and reduced spore intensity, possibly due to inter-specific competition. This is the first long-term laboratory study to demonstrate lethal consequences of N. apis and N. ceranae and mixed Nosema parasitism in honey bees, and suggests that differences in reproduction and intra-host competition may explain apparent heterogeneous exclusion of the historic parasite by the invasive species

Up to 15 people can participate in the game, which is supervised by a moderator. Households consisting of 1-5 people discuss options for diversification of household strategies. Aim of the game: By devising appropriate strategies, households seek to stand up to various types of events while improving their economic and social situation and, at the same time, taking account of ecological conditions. The annual General Community Meeting (GCM) provides an opportunity for households to create a general set-up at the local level that is more or less favourable to the strategies they are pursuing. The development of a community investment strategy, to be implemented by the GCM, and successful coordination between households will allow players to optimise their investments at the household level. The household who owns the most assets at the end of the game wins. Players participate very actively, as the game stimulates lively and interesting discussions. They find themselves confronted with different types of decision-making related to the reality of their daily lives. They explore different ways to model their own household strategies and discuss risks and opportunities. Reflections on the course of the game continually refer to the real-life situations of the participants.

Literature on hypertension treatment has demonstrated that a healthy life style is one of the best strategies for hypertension control. In exploring the mechanisms of behavioral change for hypertension control, a comprehensive study based on the Transtheoretical Model was carried out in Taiwan during the summer of 2000 with a sample of 350 hypertensive adults living in Taipei urban and rural areas. ^ The relationships among stages of change, processes of change and demographic factors were analyzed for six health behaviors—low fat food consumption, alcohol use, smoking, physical activity, weight control, and routine blood pressure checkups. In addition, differences were assessed between urban and rural populations in changing their behavior for hypertension control. ^ The results showed that rural populations had more difficulties than urban populations in avoiding smoking and engaging in physical activity, and the processes of change being used by urban populations were significantly greater than rural populations. The study findings support a strong association between processes and stages of change. ^ Individuals who use more processes of change will be more inclined to move from precontemplation stage to maintenance stage. Counterconditioning, which is the substitution of alternatives for the problem behaviors, in this study, significantly helped people to change diet, engage in physical activity, and check blood pressure regularly. For example, counterconditioning is eating more vegetables instead of meat, or engaging in physical activity as a time to relax rather than another task to accomplish. ^ In addition, self-reevaluation was the most important process for helping people to engage in physical activity; and social liberation was the most important process for changing diet behavior. The findings in this study may be applied to improve health behaviors among rural populations with low income and low education; however, at the same time, the obesity problems among urban populations should be prevented to control hypertension in Taiwan. ^

This dissertation is an examination of the ideals and practices that have characterized Western culture's relationship to the natural world. The conventional approach, depicted by some of the most prominent ecological publications of recent years, criticizes the Western tradition for both its ideals and practices. The ideals are assumed to be best represented in Western philosophy and religion and both of these sources have been indicted. These ideals are coupled with the Western way of life that is equally indicted as exploitive and destructive. Author, professor and farmer, Wendell Berry, offers an alternative to these indictments. Berry insists that a theme, advocating ecological accountability, runs through some of the West's most significant literature and that Western tradition contains a practice that can support these ecological principles. ^

Little is known about HIV stigma in Nepal. Findings from other parts of the world suggest that HIV related stigma acts as a limiting factor for People Living with HIV & AIDS (PLHAs) from accessing needed health care and the subsequent psychological outcomes make PLHAs and their immediate family members more vulnerable. The purpose of this study is to understand and describe Nepalese PLHA's and community peoples' experiences regarding sources, types, causes and mechanism of HIV-associated stigma. This study aimed to best utilize the existing data. Study participants were recruited through local Community Based Organizations working in the field of HIV. The data, collected in the form of focus group discussions in workshop settings, were coded and analyzed. Study has revealed key issues related to HIV stigma in Nepal: hierarchy of stigma, denial and rejection, death as a form of punishment and Mumbaiya disease. A conceptual model was developed to explain the HIV stigma in Nepal. Our hope is that this finding, stigma being a contextual variable, will be helpful in triggering a novel public health discourse in the field of HIV stigma in Nepal, which will eventually be helpful for developing policies and interventions to eliminate HIV-associated stigma.^

A community bioassay of copper was performed using benthic macroinvertebrates colonized on multiplate substrate samplers. Five copper concentrations ranging from 0.080-2.20 mg/l total copper were administered to five artificial streams by a Mount and Brungs proportional dilutor. Free copper ion as Cu('++) ranged from .002-.053 mg/l. A sixth stream received no copper and served as a control. Substrates were sampled at days 0, 14, and 28, and the results were used to compare 13 indices used or proposed to assess aquatic environmental impact. Sensitivity of the indices to changes in communities with respect to concentration and time was the basis for the comparison.^ Results indicated that all of the 8 diversity or richness indices tested gave approximately the same result (with the exception of number of species); they increased over the first 2-3 concentrations, then declined. Included among these was the Shannon index which gave false positive results, i.e., it increased, indicating enrichment, when in fact perturbation had occurred. This result was due to the disproportionate effect on the most abundant taxa, which caused a more even distribution of individuals among species. Number of species and individuals declined with increased concentration and time, with only one exception in the case of species, indicating perturbation.^ Results of five community comparison indices were varied at day 14 but by day 28 the results indicated a clear, nearly monotonic, trend due to copper impact. It was assumed that day 28 observations, though probably still changing, were nearer stability than at day 14 and therefore more representative of natural conditions. The changes in community comparison indices showed good agreement at 28 days and reflected the general decline in species and individuals. No single community comparison index could be set apart as superior to the others. ^
