This article introduces to policy studies the concept of valence, which we define as the emotional quality of an idea that makes it more or less attractive. We argue that valence explains why some ideas are more successful than others, sometimes gaining paradigmatic status. A policy idea is attractive when its valence matches the mood of a target population. Skilled policy entrepreneurs use ideas with high valence to frame policy issues and generate support for their policy proposals. The usefulness of the concept of valence is illustrated with the case of sustainability, an idea that has expanded from the realm of environmental policy to dominate discussions in such diverse policy areas as pension reform, public finance, labor markets, and energy security. As the valence of sustainability has increased, policy entrepreneurs have used the idea to reframe problems in these various policy areas and promote reforms.  相似文献

Information about the support given by the public opinion to political actors has become a constant element of the public debate in Poland after the fall of Communism. Very soon polls became an argument in debates, a premise, or a way to justify decisions. At the same time they were criticized both by politicians and journalists convinced that polls can significantly influence the election results. But the fact was not noticed in Poland that all debates about the influence of polls on election outcomes should be preceded by a discussion of the way they are presented in the media. The present article joins this debate by subjecting to analysis the polls published in the Polish press during parliamentary campaigns in the dimensions of the role they played during the recent several years, the quality of methodological information, and of the way the polls were used in the media.As opposed to European and American analyses, no improvement in the conformity to standards of minimal disclosure in newspapers’ reporting of public opinion polls was noticed, although—like in other countries—a dramatic increase in the number of polls reported was observed.  相似文献

Research indicates that subjective perceptions of socioeconomic status (SES) affect aspects of health and behavior. There has been little research attention to how objective (e.g., education) and subjective aspects of SES may differ in their influence on the substance use of adolescent immigrants. The present study examined whether the associations between subjective SES and substance use, and between parental education and substance use varied by immigrant generation. Data were derived from the 2011 Ontario Student Drug Use and Health Survey, a representative survey of students in the 7th to 12th grade. The sample for this study consisted of 9177 students 12–19 years of age; 48.4 % were female, 66.4 % were White/European, 5.2 % Black/Afro-Caribbean, 16.4 % Asian and 12 % other. Results indicated that subjective SES was more strongly associated with cannabis and alcohol use among first-generation immigrants than among adolescents of other immigrant generations even after adjusting for parental education. First-generation immigrants with low subjective SES had a lower probability of cannabis and regular alcohol use, but there was no difference in use between immigrant generations at high subjective SES. The associations between parental education and cannabis and alcohol use did not significantly vary with immigrant generation. The findings highlight the importance of status beliefs among adolescents, particularly among first-generation immigrants, and suggest that further research attention to such beliefs would enhance our understanding of SES and its links to adolescent health risk behaviors.  相似文献

Many Unemployment Insurance (UI) recipients do not find new jobs before exhausting their benefits, even when benefits are extended during recessions. Using Survey of Income and Program Participation (SIPP) panel data covering the 2001 and 2007 to 2009 recessions and their aftermaths, we identify individuals whose jobless spells outlasted their UI benefits (exhaustees) and examine household income, program participation, and health‐related outcomes during the six months following UI exhaustion. For the average exhaustee, the loss of UI benefits is only slightly offset by increased participation in other safety net programs (e.g., food stamps), and family poverty rates rise substantially. Self‐reported disability also rises following UI exhaustion. These patterns do not vary dramatically across household demographic groups, broad income level prior to job loss, or the two business cycles. The results highlight the unique, important role of UI in the U.S. social safety net.  相似文献

Manufacturing plant closure has been the subject of much national concern, and an extensive literature principally focused on the developed world. This study extends the findings on plant closure with an analysis of export-oriented manufacturers (maquiladoras) in Mexico, 1996–2006. The foci of this research are hypothesised variables of maquiladora closure: product manufactured (value-added), size of plant, plant location, and size of urban place. The results of a logistical regression model indicate that plant size and value-added are highly probable determinants of plant closure; large, high value-added product maquiladoras have low rates of plant closure. Maquiladoras manufacturing low value-added products have high rates of closure; however, these manufacturers also have significant numbers of surviving plants. This suggests that multiple manufacturing platforms are viable among Mexico’s export-oriented industry. The findings also suggest that much plant closure is a result of exogenous factors,exiting plants in a global search for cheap labour. Mexico, however, has a geographic comparative advantage that, for many maquiladoras, trumps wages in more distant locations.  相似文献
