This paper studies natives’ economically motivated preferences over different levels of immigration of low-income earners. Immigration affects natives through both intra- and intergenerational redistribution programmes and in the labour market. Our analysis suggests, in a welfare state that looks after the poor and the aged, economic motivation does not necessarily lead a native to have an extreme opinion on the preferable level of immigration, although it causes disagreement among natives. We find, regardless of parameter values, high-income earners prefer at least as much immigration as low-income earners who, in turn, prefer at least as much immigration as pensioners. The median voter is then likely to be a low-income native.

The aim of this work is to propose a tool for measuring a complex concept, and to apply it to big sets of data measured on ordinal and/or dichotomous scales. An important field of application are subjective data, that are often based on opinions or personal evaluations. Many national and international surveys employ this kind of data, measured among thousand of individuals. Thanks to the use of the “average rank” as a synthetic measure of a complex concept, we believe that poset theory could be a very useful approach for dealing with ordinal data avoiding the use of scaling procedures. Because classic poset approaches are at their best when applied to few data at a time, our idea is based on a procedure for sampling units from a big population using a simple criterion to summarize the resulting values appropriately. Applying the central limit theorem enables a comparison of the results obtained from different groups using statistical tests on the means. We used our Height of Groups by Sampling (HOGS) method to compare the average rank among groups that are defined by one or more socio-demographic variables influencing the level of the complex concept we wish to measure. The application of the HOGS procedure to life satisfaction in Italy generated convincing results, revealing significant differences between regions, genders and levels of formal education. We compared the results given by HOGS with the non linear principal component analysis and obtain an easy readable output with convincing precision and accuracy; we are confident that the HOGS procedure can be applied to many other concepts investigated in the social sciences. 相似文献

Although human trafficking is recognized as a major human rights violation, there is limited evidence regarding the vulnerabilities that contribute to female adolescents’ risk of being forced or coerced into the sex trade. Vulnerabilities such as gender‐based violence, economic and social inequalities have been shown to shape the risk of sexual exploitation among adolescents. In‐depth interviews (n=18) with current sex workers who reported being deceived or forced into the sex trade as adolescents (<17 years old) were analysed to explore their experiences of migration and mobility in Mexico. Driven by socio‐economic and vulnerabilities in home communities, adolescents often engaged in internal migration and mobility to other Mexican communities and states. Migration and mobility further predisposed them to social isolation, economic hardship and abuse, which were used as tools to trick them into the sex trade. Policies that support safer migration for adolescents in origin, transit, and destination communities are needed. 相似文献

This study introduces the Satisfaction with Life Scale adapted for Children (SWLS-C) and presents psychometric findings regarding
its validation. The SWLS-C was adapted from the Satisfaction with Life Scale (SWLS; Diener et al. 1985), which is one of the most commonly used measures to assess satisfaction with life in adults. Three subject matter experts
adapted the SWLS by changing the wording of the item stem and response format in order to make it more understandable for
children. A stratified random sample of 1,233 students (48% girls) in grades 4–7 (mean age 11 years and 7 months) provided
data on the SWLS-C and measures of optimism, self-concept, self-efficacy, depression, emphatic concern, and perspective taking.
The SWLS-C demonstrated a unidimensional factor structure and high internal consistency. Furthermore, differential item functioning
and differential scale functioning analyses indicated that the SWLS-C measures satisfaction with life in the same way for
different groups of children (i.e., with regard to gender, first language learned at home—English vs. other language(s) than
English—and across different grades) at the item and at the scale level. Associations between scores on the SWLS-C and demographic
variables were statistically non-significant or of small effect size. In addition, the SWLS-C showed evidence of convergent
and discriminant validity in relation to the other measures. Our results indicate that the SWLS-C is a psychometrically sound
instrument that demonstrated evidence of construct validity for this age group. Limitations and future directions are discussed. 相似文献

The division problem consists of allocating a given amount of a homogeneous and perfectly divisible good among a group of
agents with single-peaked preferences on the set of their potential shares. A rule proposes a vector of shares for each division
problem. The literature has implicitly assumed that agents will find acceptable any share they are assigned to. In this article
we consider the division problem when agents’ participation is voluntary. Each agent has an idiosyncratic interval of acceptable
shares where his preferences are single-peaked. A rule has to propose to each agent either to not participate or an acceptable
share because otherwise he would opt out and this would require to reassign some of the remaining agents’ shares. We study
a subclass of efficient and consistent rules and characterize extensions of the uniform rule that deal explicitly with agents’
voluntary participation. 相似文献

Strategy-proof and anonymous rule in queueing problems: a relationship between equity and efficiency
We consider a relationship between equity and efficiency in queueing problems. We show that under strategy-proofness, anonymity
in welfare implies queue-efficiency. Furthermore, by combining the result of Kayı and Ramaekers (Games Econ Behav 68:220–232,
2010) with ours, we also give a characterization of the class of rules that satisfy strategy-proofness, anonymity in welfare,
and budget-balance. 相似文献

We investigate the implications of balanced consistency and balanced cost reduction in the context of sequencing problems. Balanced consistency requires that the effect on the payoff from the departure of one agent to another agent should be equal between any two agents.
On the other hand, balanced cost reduction requires that if one agent leaves a problem, then the total payoffs of the remaining agents should be affected by the amount
previously assigned to the leaving agent. We show that the minimal transfer rule is the only rule satisfying efficiency and Pareto indifference together with either one of our two main axioms, balanced consistency and balanced cost reduction. 相似文献

Objective
The aim of this study was to investigate the effect of experience of childhood abuse among university students on self-perception and submissive behavior.Methods
The study group consisted of 646 students attending various departments of the Karadeniz Technical University Faculty of Education in Trabzon, Turkey. Participants were administered the Childhood Trauma Questionnaire, the Social Comparison Scale and the Submissive Acts Scale in a classroom setting.Results
Analysis revealed a significant negative correlation between self-perception and all forms of abuse (physical abuse, sexual abuse, and emotional abuse and neglect), and a positive correlation between submissive behavior and all forms of abuse. The students' emotional abuse and neglect scores varied significantly according to gender, with males having higher emotional abuse and neglect scores than those of girls. Additionally, males had higher physical abuse scores than girls.Conclusion
Childhood abuse emerged as a significant predictor of negative self-perception and submissive behavior. In addition, with the exception of sexual abuse, other forms of abuse vary according to gender. The experiences of childhood abuse may have a long-term impact on various features of character and behavior. 相似文献60.
