Flasher Powered by Photovoltaic Cells and Ultracapacitors

A unique safety flasher powered by photovoltaic cells and ultracapacitors has been developed. Safety flashers are used wherever there are needs to mark actually or potentially hazardous locations. Examples of such locations include construction sites, highway work sites, and locations of hazardous operations. Heretofore, safety flashers have been powered by batteries, the use of which entails several disadvantages: Batteries must be kept adequately charged, and must not be allowed to become completely discharged. Batteries have rather short cycle lives, and their internal constituents that react chemically to generate electricity deteriorate (and hence power-generating capacities decrease) over time. The performances of batteries are very poor at low temperatures, which often occur in the circumstances in which safety flashers are most needed. The disposal of batteries poses a threat to the environment. The development of the present photovoltaic/ultracapacitor- powered safety flasher, in which the ultracapacitors are used to store energy, overcomes the aforementioned disadvantages of using batteries to store energy. The ultracapacitors in this flasher are electrochemical units that have extremely high volumetric capacitances because they contain large-surface-area electrodes separated by very small gaps. Ultracapacitors have extremely long cycle lives, as compared to batteries; consequently, it will never be necessary to replace the ultracapacitors in the safety flasher. The reliability of the flasher is correspondingly increased, and the life-of-system cost and the adverse environmental effects of the flasher are correspondingly reduced. Moreover, ultracapacitors have excellent low-temperature characteristics, are maintenance-free, and provide consistent performance over time

Photovoltaic Power Station with Ultracapacitors for Storage

A solar photovoltaic power station in which ultracapacitors, rather than batteries, are used to store energy is discussed. Developments in the semiconductor industry have reduced the cost and increased the attainable efficiency of commercially available photovoltaic panels; as a result, photovoltaic generation of power for diverse applications has become practical. Photovoltaic generation can provide electric power in remote locations where electric power would otherwise not be available. Photovoltaic generation can also afford independence from utility systems. Applications include supplying power to scientific instruments and medical equipment in isolated geographical regions

Gender Difference or Parallel Publics? The Dynamics of Defense Spending Opinions in the United States, 1965-2007

Gender is now recognized as an important dividing line in American political life, and scholars have accumulated evidence that national security issues are an important reason for gender differences in policy preferences. We therefore expect that the dynamics of support for defense spending among men and women will differ. In contrast, several scholars have shown that population subgroups exhibit a ‘‘parallel’’ dynamic in which the evolution of their preferences over time is very similar, despite differences in the average level of support. Unfortunately, there is little time series evidence on gendered reactions to policy, including defense spending, that would allow one to arbitrate between these competing perspectives. In this research note, we assemble a time series of support for defense spending among men and women and model the determinants of that support for the period 1967–2007. We find that women are on average less supportive of defense spending than are men. However, we also find that the over time variation of support for defense spending among men and women is very similar—each is conditioned principally by the past year’s change in defense spending and occasionally by war casualties and a trade-off between defense and civilian spending

Stretching the IR theoretical spectrum on Irish neutrality: a critical social constructivist framework

In a 2006 International Political Science Review article, entitled "Choosing to Go It Alone: Irish Neutrality in Theoretical and Comparative Perspective," Neal G. Jesse argues that Irish neutrality is best understood through a neoliberal rather than a neorealist international relations theory framework. This article posits an alternative "critical social constructivist" framework for understanding Irish neutrality. The first part of the article considers the differences between neoliberalism and social constructivism and argues why critical social constructivism's emphasis on beliefs, identity, and the agency of the public in foreign policy are key factors explaining Irish neutrality today. Using public opinion data, the second part of the article tests whether national identity, independence, ethnocentrism, attitudes to Northern Ireland, and efficacy are factors driving public support for Irish neutrality. The results show that public attitudes to Irish neutrality are structured along the dimensions of independence and identity, indicating empirical support for a critical social constructivist framework of understanding of Irish neutrality

Globalisation from Above? Corporate Social Responsibility, the Workers' Party and the Origins of the World Social Forum

In its assessment of the origins and early development of the World Social Forum this article challenges traditional understandings of the Forum as representing ‘globalisation from below’. By tracing the intricate relations among elements of business, civil society, and the Workers’ Party in the first years of the Forum, this article reveals the major role played by a corporate movement stemming from the Brazilian democratisation process in the 1980s, and how this combined with the transformed agenda of the Workers’ Party as it gained higher political offices to constrain the Forum’s activities from the outset. In so doing, this article challenges not only widespread conceptions of the Forum as a counter‐hegemonic alternative but also current critiques concerning its subsequent limitations. Furthermore, it reveals how traditional understandings of the World Social Forum and of global civil society are underpinned by flawed assumptions which typecast political activities in the global ‘South’

Gender Difference in American Public Opinion on the Use of Military Force, 1982–2013

Recent scholarship indicates that gender correlates strongly with Americans' attitudes toward the use of military force. However, most of its evidence derives from the study of major wars, and the field needs more historical research to evaluate the evolution of gender difference over time. I redress these limitations by updating and extending my earlier (2003) analysis of public support for the use of force during the 1990s. I analyze 965 individual survey questions concerning the use of US military force in twenty-four historical episodes, beginning in 1982 with military aid to El Salvador and continuing through the recent wars in Afghanistan, Iraq, Libya, and Syria. I find that substantial gender difference characterizes a large number of historical episodes and types of military action. Nonetheless, the magnitude of gender difference varies substantially; in many cases, a substantial percentage of women supports the use of force. The difference between men and women varies most with the salience and level of violence, and women are more sensitive to humanitarian concerns. Women display more sensitivity to casualties in some historical cases, but during the wars in Iraq and Afghanistan, the casualty sensitivity of men gradually increased as the wars dragged on, and gender differences therefore decreased. Thus, I argue that scholars should turn their attention to studying individual-level differences between and among men and women in support for using military force. I also discuss the political and policy implications of the findings

Defense/Welfare Tradeoffs in West German Budgeting.

The study seeks to answer two questions: (1) Is there evidence of defense/welfare tradeoffs in German budgetary outputs? and (2) Is there evidence of partisan differences in the relationship between defense and civilian spending? The study presents a model of resource allocation within which tradeoffs can be analyzed. Given the predominance of short-term, incrementalist behavior in budgeting, we argue that tradeoffs can be analyzed in terms of expenditure change. The study introduces West German budgeting and provides a first evaluation of the likelihood of defense tradeoffs. One body of results is the regression analysis of both budgeted expenditures and final expenditures for 10 categories of civilian spending at the Federal level. The results demonstrate that factors other than defense spending are the primary determinants of expenditure change. Finally, the study investigates tradeoffs in the wider public sector. Regression analysis of state and local spending and spending of social security trust funds indicates that revenue constraints, electoral considerations and demographic pressures outweigh defense spending as correlates of spending change. The study concludes with some considerations on the generalizability of the results. In particular, we discuss the potential uniqueness of German public finances and the effect of "small state" status on the priority accorded defense spending. We raise the possibility that defense may have been relegated permanently to a secondary status by the social and political changes of the post-WWII period.Ph.D.International lawUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/158436/1/8125104.pd
