Explaining Nuclear Energy Pursuance: A Comparison of the United States, Germany, and Japan

Energy is critical to the functioning of the global economy and seriously impacts global security as well. What factors influence the extent to which countries will pursue nuclear energy in their overall mix of energy approaches? This dissertation explores this critical question by analyzing the nuclear energy policies of the United States, Germany and Japan. Rather than citizen opposition or proximity to nuclear disasters, it seems that a country\u27s access to other resources through natural endowments or trading relationships offers the best explanation for nuclear energy pursuance

The Effects of Terrorism on Public Opinion of Gun Control in the United States

The purpose of this study is to investigate the relationship between terrorist activity and public support for gun control. This thesis tests three hypotheses: 1) that out-group violence causes greater support for gun control than in-group violence, 2) that the method of violence determines support for gun control, and 3) that the results of the first two hypotheses are dependent on the conditional variables of gender, fear of Muslims, and residence in an urban or rural area. To analyze these relationships, a survey experiment was conducted to determine if out-group violence and method of violence had an affect on public support for gun control. The results of this study showed no significant increased support for gun control when violence was perpetrated by an out-group member, and the method of violence also appeared to have no affect in the general population. However, when these relationships were analyzed across conditional variables, certain characteristics, especially gender, had an affect of gun policy opinions and other security preferences. This study concludes that although no generalizable results were found in this analysis, there is much room for greater exploration of the topic along other conditional variables

Meeting the challenge of population ageing.

The welfare state is based on a life course that no longer matches current experience. It assumes that people, or at least men and unmarried women, spend their early years in education and then go on to a long period in work followed by a short period in retirement, when they live off the pension accumulated while in work or, more usually, the tax and pension contributions of those still in work. At a time when many people did not survive to draw their pensions or, if they did, survived for only a few more years, welfare systems coped reasonably well. It is less clear whether they will be able to do so in the future. The scale of the challenge is shown by a single stark statistic. If there is no change in work and retirement patterns, the ratio of workers to older inactive persons in the countries that were European Union member states in May 2004 (the EU-25), now at 3:1, is projected to increase to 1:1 in 2050

Cloned, CD117 Selected Human Amniotic Fluid Stem Cells Are Capable of Modulating the Immune Response

Amniotic fluid stem (AFS) cells are broadly multipotent, can be expanded extensively in culture, are not tumorigenic and can be readily cryopreserved for cell banking. Mesenchymal stem cells (MSC) show immunomodulatory activity and secrete a wide spectrum of cytokines and chemokines that suppress inflammatory responses, block mixed lymphocyte reactions (MLR) and other immune reactions, and have proven therapeutic against conditions such as graft-versus-host disease. AFS cells resemble MSCs in many respects including surface marker expression and differentiation potential. We therefore hypothesized that AFS cells may exhibit similar immunomodulatory capabilities. We present data to demonstrate that direct contact with AFS cells inhibits lymphocyte activation. In addition, we show that cell-free supernatants derived from AFS cells primed with total blood monocytes or IL-1β, a cytokine released by monocytes and essential in mediation of the inflammatory response, also inhibited lymphocyte activation. Further investigation of AFS cell-free supernatants by protein array revealed secretion of multiple factors in common with MSCs that are known to be involved in immune regulation including growth related oncogene (GRO) and monocyte chemotactic protein (MCP) family members as well as interleukin-6 (IL-6). AFS cells activated by PBMCs released several additional cytokines as compared to BM-MSCs, including macrophage inflammatory protein-3α (MIP-3α), MIP-1α and Activin. AFS cells also released higher levels of MCP-1 and lower levels of MCP-2 compared to BM-MSCs in response to IL-1β activation. This suggests that there may be some AFS-specific mechanisms of inhibition of lymphocyte activation. Our results indicate that AFS cells are able to suppress inflammatory responses in vitro and that soluble factors are an essential component in the communication between lymphocytes and AFS cells. Their extensive self-renewal capacity, possibility for banking and absence of tumorigenicity may make AFS cells a superior source of stable, well characterized “off the shelf” immunomodulatory cells for a variety of immunotherapies

Peer support for people living with rare or young onset dementia: An integrative review

OBJECTIVES: The aim of this integrative review was to identify and synthesize the literature on peer support interventions for people living with or caring for someone with a rare or young onset dementia. DESIGN: A literature search of articles was performed using the Nipissing University Primo search system, a central index that enables simultaneous searches across databases which included MEDLINE (PubMed), Web of Science, PsycINFO, CINAHL, Sociological Abstracts, Cochrane Library. RESULTS: The eleven papers that met the inclusion criteria spanned eighteen years and from five countries. Studies reported on peer support programs that were either hospital-based (n = 6) or community-based (n = 4), and were predominantly led by disciplines in the health sciences. Only one study did not involve delivering services. There was a range of methodological quality within the studies included in the review. Further analysis and synthesis led to the identification of three overarching peer support themes. These included: (1) peers as necessarily part of social support interventions; (2) a theoretical portmanteau; and (3) dementia spaces and relationality. CONCLUSION: Consistent with a much larger body of work examining peer involvement in social interventions, this review reinforced the valuable contribution of peers. A full understanding of the mechanisms of change was not achieved. Notwithstanding, the issue of studies neglecting to sufficiently conceptualize and describe interventions is an important one – drawing attention to the need to continue to explore varied delivery, including co-produced models, and more effective evaluation strategies to inform the dementia care sector

Parent Depression and Child Anxiety: An Overview of the Literature with Clinical Implications

The association of parental depression with child anxiety has received relatively little attention in the literature. In this paper we initially present several reasons for examining this relationship. We then summarize the empirical support for a link between these two variables. Finally, we discuss directions for future research and clinical implications of an association of parental depression with child anxiety

A submillimetre survey of the kinematics of the Perseus molecular cloud - III. Clump kinematics

We explore the kinematics of continuum clumps in the Perseus molecular cloud, derived from C18O J=3-2 data. Two populations are examined, identified using the automated algorithms CLFIND and GAUSSCLUMPS on existing SCUBA data. The clumps have supersonic linewidths with distributions which suggest the C18O line probes a lower-density 'envelope' rather than a dense inner core. Similar linewidth distributions for protostellar and starless clumps implies protostars do not have a significant impact on their immediate environment. The proximity to an active young stellar cluster seems to affect the linewidths: those in NGC1333 are greater than elsewhere. In IC348 the proximity to the old IR cluster has little influence, with the linewidths being the smallest of all. A virial analysis suggests that the clumps are bound and close to equipartition. In particular, the starless clumps occupy the same parameter space as the protostars, suggesting they are true stellar precursors and will go on to form stars. We also search for ordered C18O velocity gradients across the face of each core, usually interpreted as rotation. We note a correlation between the directions of the identified gradients and outflows across protostars, indicating we may not have a purely rotational signature. The fitted gradients are larger than found in previous work, probably as a result of the higher resolution of our data and/or outflow contamination. These gradients, if interpreted solely in terms of rotation, suggest that rotation is not dynamically significant. Furthermore, derived specific angular momenta are smaller than observed in previous studies, centred around j~0.001 km/s pc, which indicates we have identified lower levels of rotation, or that the C18O J=3-2 line probes conditions significantly denser and/or colder than n~10^5 per cc and T~10 K.Comment: 20 pages, 20 figures, accepted for publication by MNRAS.
