Constrained allocation problems with single-peaked preferences: An axiomatic analysis 总被引:1,自引:0,他引:1
Özgür Kıbrıs 《Social Choice and Welfare》2003,20(3):353-362
We introduce a new class of problems that contains two existing classes: allocation problems with single-peaked preferences
and bankruptcy problems. On this class, we analyze the implications of well-known properties such as Pareto optimality, strategy-proofness,
resource-monotonicity, no-envy, equal treatment of equals, and two new properties we introduce, hierarchical no-envy and independence
of nonbinding constraints. Unlike earlier literature, we consider rules that allow free-disposability. We present characterizations
of a rule we introduce on this domain. We relate this rule to well-known rules on the aforementioned subdomains. Based on
this relation, we present a characterization of a well-known bankruptcy rule called the constrained equal awards rule.

ABSTRACTThe present study aimed to compare attitudes toward lesbians and gay men across three generations in Turkey. Participants were 112 young people, 169 parents, and 125 grandparents. A total of 406 men and women were involved. The short form of Herek's (1998) the Attitudes Toward Lesbians and Gay Men Scale was used. MANOVAs and ANOVAs were used to analyze the data. Results showed the attitudinal differences toward gay and lesbian people across generations. Grandparents have the most negative attitudes, whereas parents have more negative attitudes than their children. When comparing attitudes of each generation across sex, we found that young women have more liberal attitudes toward gay men compared to all other groups. Discussion focuses on understanding the results within the unique cultural context of Turkey. 相似文献

Since Esping‐Andersen's Three Worlds, it has become a truism of welfare state research that welfare states do not vary linearly along a single dimension but have to be conceptualized as multidimensional phenomena that cluster into types caused by the political economy of class coalitions. However, when moving beyond the 18 original countries of Esping‐Andersen's analysis, the situation is less clear. Although additional worlds have been identified in the Global North and the Global South, these are usually not conceptualized along the same dimensions as the original three worlds and are rarely empirically compared with them. This paper tackles these omissions by explicitly comparing Northern and Southern countries within Esping‐Andersen's framework. It poses the question whether the central insight of welfare state research, namely, that there are not just gradual differences between welfare states, but different types with qualitative differences, expands beyond classic welfare states. Based on newly generated data on social rights and social stratification, we employ cluster analysis with 45 Northern and Southern countries. This analysis produces mixed results. We do find different types of welfare states with qualitative differences, but these do not fully correspond to Esping‐Andersen's Three Worlds. Moreover, our findings also point to a conceptual issue in welfare regime research: regimes are not just defined and measured in terms of different logics of welfare provision but also take into account degrees of welfare stateism. We argue that this issue is poised to become ever more pressing with the geographical expansion of welfare state research. 相似文献

Demographic ageing is a challenge for many countries. Even though Turkey has a relatively younger demographic composition, the proportion of the older people (65+) within the population is rapidly increasing. Within this framework, older people are becoming more important clients for both social work students and social workers in Turkey. This study aims to reveal the attitudes of social work students towards older people and determine the various factors that affect their views on older persons. In the scope of the project, Kogan's Attitude Towards Old People Scale was applied to 419 social work undergraduate students at a university located in Central Anatolia. The findings showed that social work students scored a mean of 130.96 and they generally had positive attitudes towards older people. The correlation between year of study, gender and age was not statistically significant. However, having lived mostly in urban areas was positively correlated with the mean Kogan scores and this finding was found to be statistically significant. Exposure to personal contact with older people at both the personal and professional levels was influential in shaping attitudes about the older people. 相似文献

ABSTRACT Since the 2001 economic crisis, conditional cash transfers (CCTs) have been provided to poor families in Turkey to improve education and health outcomes of children. Under the framework of CCT programs, grants provide an incentive for poor households to use available basic social services. The aim of this study is to explore beneficiaries’ perspectives in relation to a CCT program in Turkey. The in-depth study design entailed semistructured qualitative interviews with beneficiary households and key informants. A total of 397 in-depth interviews were conducted. Analysis results suggest that the CCT program not only positively affected health and educational outcomes, but also contributed to the empowerment of women and improved the self-esteem and self-confidence of beneficiary children. Recommendations for future research are made including the need for an impact evaluation analysis that employs quantitative research methods designed to improve the provision and quality of the basic social services. 相似文献

In this study, it was aimed to determine accuracy of generalized estimating equations versus logistic regressions on different correlation levels and sample sizes. For this aim, two methods were compared with different sample sizes 10, 25, 50 and 100 and correlation levels 0.0, 0.3, 0.5 and 0.8. Result of this study showed that using generalized estimating equations could be preferred versus logistic regression when the sample size is over than 25 and correlation level is higher than 0.3 on data taken from studies with repeated measurements, but logistic regression could be better when the autocorrelations do not exist. 相似文献

The purpose of this study is to highlight the application of sparse logistic regression models in dealing with prediction of tumour pathological subtypes based on lung cancer patients'' genomic information. We consider sparse logistic regression models to deal with the high dimensionality and correlation between genomic regions. In a hierarchical likelihood (HL) method, it is assumed that the random effects follow a normal distribution and its variance is assumed to follow a gamma distribution. This formulation considers ridge and lasso penalties as special cases. We extend the HL penalty to include a ridge penalty (called ‘HLnet’) in a similar principle of the elastic net penalty, which is constructed from lasso penalty. The results indicate that the HL penalty creates more sparse estimates than lasso penalty with comparable prediction performance, while HLnet and elastic net penalties have the best prediction performance in real data. We illustrate the methods in a lung cancer study. 相似文献
