The application of the theory of partially ordered sets to voting systems is an important development in the mathematical theory of elections. Many of the results in this area are on the comparative properties between traditional elections with linearly ordered ballots and those with partially ordered ballots. In this paper we present a scoring procedure, called the partial Borda count, that extends the classic Borda count to allow for arbitrary partially ordered preference rankings. We characterize the partial Borda count in the context of weighting procedures and in the context of social choice functions. 相似文献
Two different perspectives on immigration outcomes are employed and interrelated: Overall assessments of the success in immigration
and systemic quality of life assessments (using SQOL model, Shye in Soc Indic Res, 21:243–378, 1989). Data were collected
from a sample of 337 immigrants to Israel from the former USSR. Results reveal that quality of life is a good indicator of
perceived success in immigration and that, of the 16 SQOL components, the expressive and the conservative modes of the personality
and of the social subsystems are the four most important SQOL components that determine successful immigration. The findings
underscore the value of using a comprehensive theory-based conception of quality of life in immigration research. 相似文献
The rate of urbanization is far more rapid in sub-Saharan Africa than in any other major region of the world. However, little
is known about patterns of ethnic residential segregation in rapidly urbanizing African cities. This paper is crafted to make
an important contribution through its focus on Ghana’s two largest cities: Accra and Kumasi. Making use of the most recent
population and housing census data of 2000 to generate a Location Quotient index, the analyses explore the cities’ degree
of ethnic diversity and concentration for comparative purposes. In relative terms, the study reveals that the level of residential
ethnic segregation is fairly balanced in Accra compared to Kumasi. However, there are important differences between the findings
of this Ghanaian case study and findings from research in the West, where the residential segregation is heavily determined
by cultural/racial factors in addition to socio-economic factors. In the absence of institutional and ethnic discrimination,
the most fundamental underlying cause of segregation in the Ghanaian case appears to be the socio-economic circumstance of
ethnic groups present in the cities. The paper concludes by exploring the implications of the study for urban and national
development in Ghana as well as the future patterns of ethnic clustering likely to emerge in Accra and Kumasi. 相似文献
Scotland has a lower life expectancy than any country in Western Europe or North America, and this disadvantage is concentrated above age 50. According to the Human Mortality Database, life expectancy at age 50 has been lower in Scotland than in any other developed country since 1980. Relative to 15 developed countries that we have chosen for comparison, Scotland's life expectancy in 2009 at age 50 was lower by an average of 2.5?years for women and 1.6?years for men. We estimate that Scottish women lost 3.6?years of life expectancy at age 50 as a result of smoking, compared to 1.4?years for the comparison countries. The equivalent figures among men are 3.1 and 2.1?years. These differences are large enough for the history of heavy smoking in Scotland to account both for most of the shortfall in life expectancy for both sexes and for the country's unusually narrow sex differences in life expectancy. 相似文献
When a subordinate receives abusive treatment from a supervisor, a natural response is to retaliate against the supervisor. Although retaliation is dysfunctional and should be discouraged, we examine the potential functional role retaliation plays in terms of alleviating the negative consequences of abusive supervision on subordinate justice perceptions. Based on the notion that retaliation following mistreatment can restore justice for victims, we propose a model whereby retaliation following abusive supervision alleviates the negative effect of abusive supervision on subordinate justice perceptions. In two experimental studies (Study 1 and 2), whereby we manipulated abusive supervision and subordinate symbolic retaliation—in particular, harming a voodoo doll that represents the abusive supervisor—we found general support for our predictions. Theoretical and practical implications are discussed. 相似文献
We analyze the effect of open access (OA) status of journal articles on citations. Using cross‐sectional and panel data from mathematics and economics, we perform negative binomial, Poisson, and generalized method of moments/instrumental variable methods regressions. We benefit from a natural experiment via hybrid OA pilot agreements. Citations to pre‐prints allow us to identify the intrinsic quality of articles prior to journal publication. Overall, our analysis suggests that there is no hybrid OA citation benefit. However, for the subpopulation of articles without OA pre‐ or post‐prints, we find positive hybrid OA effects for the full sample and each discipline separately. (JEL L17, O33, A11) 相似文献
While some research has uncovered racial differences in patterns of pornography viewership, no studies to date have considered how these patterns may be changing over time or how these trends may be moderated by other key predictors of pornography viewership—specifically, gender and religion. Using nationally representative data from the 1973–2016 General Social Survey (GSS; N = 20,620), and taking into account different ethnoreligious histories with pornography as a moral issue, we examined how race, gender, and religion intersect to influence trends in pornography viewership over 43 years. Analyses revealed that Black Americans in general were more likely to view pornography than Whites, and they were increasing in their pornography viewership at a higher rate than Whites. Moreover, Black men were more likely to consume pornography than all other race/gender combinations, but differed only from White women in their increasing rate of pornography viewership. Lastly, frequent worship attendance moderated trends in pornography viewership only for White men. By contrast, regardless of attendance frequency, Black men and women showed increasing rates of pornography use, while White women showed flat rates. We conclude by discussing the implications of these findings for research on the intersections of race, gender, religion, and sexuality. 相似文献
The volunteer experience in organizational context has received far less scrutiny. Studies have indicated specific organizational settings, such as schedule flexibility, orientation and training, empowerment, social interaction, reflection, and rewards, and each has certain influences on their satisfaction and intention of remain. But we do not know their combined impact as organizational facilitators. This study focused on a sample of hospital volunteering, which occupies the largest service hours of volunteering work in Taiwan. We explored the experience of organizational facilitators that affect the satisfaction and loyalty of the volunteers from 868 valid questionnaires in a metropolitan hospital. The results showed that volunteers with more experiences on social interaction, reflections, and rewards, were more satisfied. In term of loyalty, volunteers with higher satisfaction showed higher willing to remain, recommend, accept services, and donate. Furthermore, because of flexible schedules and preferable rewards, the volunteers were more willing to remain; because of more training, higher social interaction, reflections, and rewards, the volunteers were more willing to recommend volunteering and accept services. Additionally, less flexible schedules, better empowerment, and more reflections as well as rewards influenced volunteers to be more motivated to donate. Implications of organizational efforts toward the hospital volunteer management are discussed.
