POLICY AND INTERVENTION CONSIDERATIONS OF A NETWORK ANALYSIS OF STREET GANGS,

CRIMINOLOGY AND PUBLIC POLICY, Issue 3 2005
JEAN MARIE MCGLOIN
Research Summary: This study details a network analysis of the street gang landscape in Newark, New Jersey. Using individual gang members as the unit of analysis and multiple layers of associations as the linkages within the networks, the results suggest that the gangs in Newark are loosely organized with pockets of cohesion. In addition, there is variation with regard to individual connectedness within the gangs, and certain gang members emerge as "cut-points" or the only connection among gang members or groups of gang members. Policy Implications: The results lend further credence to the notion that problem analysis should precede gang interventions. In particular, the findings suggest that particular groups of gang members may be amenable to the collective accountability tactic, whereas others may become more cohesive as a consequence. Indeed, an intervention focused on individuals may be more productive in Newark. The cut-points within gangs are particularly worthy of attention, both for their capacity to act as communication agents for a deterrence message and for their potential vulnerability to the pulling levers strategy.

Uncovering Local Perspectives on Humanitarian Assistance and Its Outcomes

DISASTERS, Issue 2 2000
Oliver Bakewell
This paper draws on a study of Angolan refugees in Zambia to suggest ways that the perspectives and interests of the local population can be included in the assessment of relief interventions. Taking an actor-oriented approach, the paper suggests stepping back from the categorisation of the situation as an emergency and particular groups of people as the beneficiaries. Such categories are imposed from outside and may not reflect local people's outlook on the situation. In the case of Angolans in Zambia, the category of refugees had dissolved in the border villages to the extent that it was practically impossible to distinguish between refugees and hosts. This was in contrast to the official settlements where people were marked out as refugees and the label was maintained and reproduced over many years. Investigating outcomes in the border villagers in terms of refugees and the refugee problem would have been futile. The paper calls for evaluations of humanitarian assistance in complex emergencies to look beyond the ,beneficiaries' and to investigate the wider context of ,normality'. Neglecting the life and world of local people will make it impossible to understand the process by which external interventions are mediated at the local level to give particular outcomes, and valuable lessons which could help alleviate suffering will be lost.

Recent Developments in Trace Element Analysis by ICP-AES and ICP-MS with Particular Reference to Geological and Environmental Samples

GEOSTANDARDS & GEOANALYTICAL RESEARCH, Issue 1 2005
Kathryn L. Linge
This review describes recent developments in trace element analysis using inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS). It aims to focus on the application of ICP techniques to geological and environmental samples. Therefore, fundamental studies in ICP-MS and ICP-AES instrumentation have largely been ignored. Whereas the majority of literature reviewed related to ICP-MS, indicating that ICP-MS is now the preferred technique for all geological analysis, there is still a steady development of ICP-AES to environmental applications. It is clear that true flexibility in elemental analysis can only be achieved by combining the advantages of both ICP-AES and ICP-MS. Two particular groups of elements (long-lived radionuclide and the platinum-group elements) stood out as warranting dedicated sections describing analytical developments these areas. [source]


Non-random patterns in the Yellowstone ecosystem: inferences from mammalian body size, order and biogeographical affinity

GLOBAL ECOLOGY, Issue 2 2007
Judsen E. Bruzgul
ABSTRACT Aim, Our aim was to investigate how the environment, species characteristics and historical factors at the subcontinental scale affect patterns of diversity. We used the assembly of the Yellowstone biota over the past 10,000 years as a natural experiment for investigating the processes that generate a modern non-volant mammal species pool. Location, The data represent species from throughout North America with special attention to the non-volant mammals of Yellowstone National Park, USA. Methods, We used digitized range maps to determine biogeographical affinity for all non-volant mammals in the Rocky Mountains, Deserts and Great Plains biogeographical regions of North America. This biogeographical affinity, along with taxonomic order and body size class, was used to test whether non-random patterns exist in the assemblage of Yellowstone non-volant mammals. These characteristics were also used to investigate the strength of non-random processes, such as habitat or taxon filtering, on particular groups of species or individual species. Results, Our results indicated that the Yellowstone fauna is composed of a non-random subset of mammals from specific body size classes and with particular biogeographical affinities. Analyses by taxonomic order found significantly more Carnivora from the Rocky Mountains region and significantly fewer Rodentia from the Deserts region than expected from random assembly. Analyses using body size classes revealed deviations from expectations, including several significant differences between the frequency distribution of regional body sizes and the distribution of those species found within Yellowstone. Main conclusions, Our novel approach explores processes affecting species pool assembly in the Yellowstone region and elsewhere, and particularly identifies unique properties of species that may contribute to non-random assembly. Focusing on the mechanisms generating diversity, not just current diversity patterns, will assist the design of conservation strategies given future environmental change scenarios. [source]


Job displacement and stress-related health outcomes

HEALTH ECONOMICS, Issue 10 2006
Martin Browning
Abstract We investigate whether job loss as the result of displacement causes hospitalization for stress-related diseases which are widely thought to be associated with unemployment. In doing this, we use much better data than any previous investigators. Our data are a random 10% sample of the male population of Denmark for the years 1981,1999 with full records on demographics, health and work status for each person, and with a link from every working person to a plant. We use the method of ,matching on observables' to estimate the counter-factual of what would have happened to the health of a particular group of displaced workers if they had not in fact been displaced. Our results indicate unequivocally that being displaced in Denmark does not cause hospitalization for stress-related disease. An analysis of the power of our test suggests that even though we are looking for a relatively rare outcome, our data set is large enough to show even quite small an effect if there were any. Supplementary analyses do not show any causal link from displacement or unemployment to our health outcomes for particular groups that might be thought to be more susceptible.

Challenging East,West value dichotomies and essentialising discourse on culture and social work

INTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 4 2007
Vishanthie SewpaulArticle first published online: 22 MAR 200
All discourse, whether universalistic and/or particularistic, must be subject to contestation, so that we are held accountable for the thinking that we articulate in our writings, and so that we do not reinforce much of the taken for granted assumptions about the world. Critiques such as those of Hutchings and Taylor in this issue of IJSW remind us of social work's commitment to reflexivity and the need to contest discourse that might not be in the interests of particular groups of people. It is not the debate itself contained in the article that is an issue, but the framing of the debate and the assumptions upon which they are predicated. The discourse on human rights within the liberal democratic framework, in a rapidly globalising world characterised by neoliberal capitalism, needs to be critiqued on a global level. Hutchings and Taylor's article assumes the applicability and suitability of liberal democracy for the West and not for the East, with an assumption that the West is characterised by liberalism and the East by tradition and a bureaucratic authoritarianism. It is these assumptions, and the tendency to essentialise Chinese and Western culture and to reinforce the dichotomy between the West and the East, that I contest in this article. [source]


Reduced age-related plasticity of neurotrophin receptor expression in selected sympathetic neurons of the rat

AGING CELL, Issue 1 2003
T. Cowen
Summary Selective vulnerability of particular groups of neurons is a characteristic of the aging nervous system. We have studied the role of neurotrophin (NT) signalling in this phenomenon using rat sympathetic (SCG) neurons projecting to cerebral blood vessels (CV) and iris which are, respectively, vulnerable to and protected from atrophic changes during old age. RT-PCR was used to examine NT expression in iris and CV in 3- and 24-month-old rats. NGF and NT3 expression in iris was substantially higher compared to CV; neither target showed any alterations with age. RT-PCR for the principal NT receptors, trkA and p75, in SCG showed increased message during early postnatal life. However, during mature adulthood and old age, trkA expression remained stable while p75 declined significantly over the same period. In situ hybridization was used to examine receptor expression in subpopulations of SCG neurons identified using retrograde tracing. Eighteen to 20 h following local treatment of iris and CV with NGF, NT3 or vehicle, expression of NT receptor protein and mRNA was higher in iris- compared with CV-projecting neurons from both young and old rats. NGF and NT3 treatment had no effect on NT receptor expression in CV-projecting neurons at either age. However, similar treatment up-regulated p75 and trkA expression in iris-projecting neurons from 3-month-old, but not 24-month-old, rats. We conclude that lifelong exposure to low levels of NTs combined with impaired plasticity of NT receptor expression are predictors of neuronal vulnerability to age-related atrophy. [source]


Labor Market Duality and Leisure Industries in Spain: Quality of Life Versus Standard of Living

AMERICAN JOURNAL OF ECONOMICS AND SOCIOLOGY, Issue 4 2008
Juan L. Paramio
We discuss the effects that the emergence of the new postindustrial form of flexible capitalist organization has on the Spanish labor market and, by extension, on the working life of two representative groups of employees characterized by their casual and stable working conditions. This brings a growing duality in the labor market, where individuals who cannot escape casual employment coexist with those enjoying long-term contracts. This concern includes how these changes affect the nature and the ways in which these particular groups understand quality of life and standard of living, which in turn serves to call into question the "end of work" and the expected "leisure society." In addition, we highlight several circumstances that illustrate a decay in job quality and working conditions, particularly the increase in working hours. Parallel to this process we identify a work-and-spend behavior, resulting in overspent families that exhibit financial fragility and give up quality of life, associated with more free time, for higher living standards, which demand an increasing job commitment. Free time from work has become a scarce resource in Spain, and for those individuals belonging to what is known as the "new leisure class," it is associated with high-spending leisure activities, which has increased the economic importance of leisure industries.

Was kann die Aktive Arbeitsmarktpolitik in Deutschland aus der Evaluationsforschung in anderen europäischen Ländern lernen?

PERSPEKTIVEN DER WIRTSCHAFTSPOLITIK, Issue 2 2002
Viktor Steiner
Most evaluation studies for Germany's active labor market policy (ALMP) indicate that subsidized employment programs in the public sector (public works programs, "Arbeitsbeschaffungsmaßnahmen") and publicly funded training programs have, on average, no or even negative effects on individual re-employment probabilities. This paper provides possible explanations for the ineffectiveness of these programs, where we focus on heterogeneous treatment effects, which are not accounted for in the German evaluation studies due to lack of data, and locking-in effects, in particular related to the relatively high level of income support for participants in these programs. Since there is very little direct evidence on these effects for Germany to date, we draw on results from evaluation studies for other European countries. We argue that the success of ALMP is to a large extent determined by design features like the targeting of particular groups and the incentives from the co-ordination with unemployment insurance as well as the incentives of program administrators and local governments.

Differences in access to wage replacement benefits for absences due to work-related injury or illness in Canada

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 4 2009
Peter M. Smith
Abstract Background The objective of this article is to examine the factors associated with differences in access to income replacement benefits for workers experiencing a work-related injury or illness of 1-week or longer in the Canadian labor force. Methods This study utilized data from the Survey of Labour and Income Dynamics, a representative longitudinal survey conducted by Statistics Canada. A total of 3,352 work-related absences were identified. Logistic regression models examined factors at the individual, occupational, and geographic level that were associated with the probability of receiving compensation. Results The probability of not receiving employer or workers' compensation benefits was higher among women, immigrants in their first 10 years in Canada, younger workers, respondents who were in their first year of a job, those who were not members of a union or collective bargaining agreement, and part-time workers. Conclusions More research is required to understand why almost 50% of respondents with 1-week or longer work-related absences did not report receiving workers' compensation payments following their absence. More importantly, research is required to understand why particular groups of workers are more likely to be excluded from any type of compensation for lost earnings after a work-related injury and illness in Canada.

Uncounted Votes: Informal Voting in the House of Representatives as a Marker of Political Exclusion in Australia

AUSTRALIAN JOURNAL OF POLITICS AND HISTORY, Issue 1 2009
Sally Young
This article examines the implications of high levels of informal (or invalid) voting in Australian national elections using a social exclusion framework. The rate of the informal vote is an indicator of social and political exclusion with particular groups of Australians experiencing inordinate electoral disadvantage. Poorer voters, voters from non-English speaking backgrounds and those with low education levels are especially disadvantaged by factors peculiar to the Australian voting experience. We begin by exploring the character and pattern of informal voting and then canvass the technical and socio-economic factors which explain it. We conclude by considering proposed options for reducing informality, some of which are: the abandonment of compulsory voting, major structural change to the voting system as well as ballot re-design, electoral education and community information initiatives.
