Migrants are selected by several characteristics (age, education, skill, health, and family migration experience). Often less examined is religious selection. Using Guatemalan data, this research note tests whether religious affiliation is significantly associated with migration to the United States, net of other competing factors. Results are robust, demonstrating that Protestants are more likely than other religious groups to migrate. Additionally, mediating factors (social networks, cultural norms, and ideological links) are tested to identify social mechanisms behind the Protestant effect. The research note concludes with implications of religious selection and how religious selection can be further examined in migration and religion studies.  相似文献

This study explored observer performance in using across-trial and within-trial variability information to weight sources based on reliability. Three trained observers performed a multi-element, visual signal-detection task under 3 block-type conditions: a fixed block condition and 2 random conditions. In the fixed block condition, the observers had both within- and across-trial variability information to identify differences in source reliability. The random conditions eliminated the across-trial information, leaving only within-trial variability information in 1 case and neither within- nor across-trial variability information in another case. There was a significant block-type effect. Observers could use differences in across-trial variability of individual sources to assign weights. Although there was a difference in the weights assigned to reliable and unreliable sources in the partial-random condition (in which within-trial variability information was available), only 1 participant showed a significant difference in the weight assignment relative to the full-random condition. Thus, altogether, observers were not very efficient at using within-trial variability to weight sources accordingly.  相似文献

This study examines applicant reactions to ten popular selection methods in China. Using a sample of 294 graduates we found that Chinese applicants’ reactions were highly favorable for work sample tests, interviews, and written ability tests, whereas Guanxi (i.e., relying on personal contacts when applying for a job) and graphology were perceived as the least favorable selection methods. Guanxi was also perceived as significantly less fair method compared with all others on all seven procedural dimensions studied. These findings suggest that Guanxi as an informal selection channel might threaten the fairness of personnel selection in China. Implications for the design of selection systems in Chinese companies are discussed, and ramifications for future research into applicant reactions are considered.  相似文献

计算机化认知诊断自适应测验(CD_CAT)是将认知诊断的基本理论、方法与计算机化自适应测验相结合的产物,是现代测量学发展的新领域。对于计算机化自适应测验(CAT)中的选题策略研究一直是国内外学者关注的问题,然而对于计算机化认知诊断自适应测验的选题策略研究却很少报导,而对于计算机化认知诊断自适应测验的初始题选取方法的研究却更少。本研究采用计算机模拟程序对HO-DINA模型下CD_CAT的五种选题策略及二种初始题选取方法进行研究。研究表明:不同初始题选取方法及选题策略均会影响对被试诊断的准确性及能力估计的精度;总体来看,对于二种初始题选取方法,本研究提出的“T阵法”优于传统的随机法;对于五种选题策略,SL_GDI法最优;初始题选取方法及选题策略的搭配中,“T阵法”和SL_GDI法的搭配最佳。  相似文献

No one factor could have as great an impact on multinational corporations (MNCs) than the dual-career phenomena. The selection of expatriate candidates is a complex process made more arduous by the career orientation of the expatriate's spouse. The need for a social support network is essential for the dual-career family to increase the probability of successfully completing an expatriate assignment.  相似文献

Selecting scholarship students from a number of competing candidates is a complex decision making process, in which multiple selection criteria have to be considered simultaneously. Multiattribute decision making (MADM) has proven to be an effective approach for ranking or selecting one or more alternatives from a finite number of alternatives with respect to multiple, usually conflicting criteria. This paper formulates the scholarship student selection process as an MADM problem, and presents suitable compensatory methods for solving the problem. A new empirical validity procedure is developed to deal with the inconsistent ranking problem caused by different MADM methods. The procedure aims at selecting a ranking outcome which has a minimum expected value loss, when true attribute weights are not known. An empirical study of a scholarship student selection problem in an Australian university is conducted to illustrate how the selection procedure works.  相似文献

Sex and ethnic group differences were examined on the operational composites and tests used to select applicants for US Air Force officer commissioning programmes and for pilot training. Results showed that large mean score differences in applicant samples were substantially reduced among the pilot trainees. Despite differences in test performance, there was no evidence of differential validity for groups. When group differences in predicted pilot training completion rate were observed, performance was overestimated for the minority group relative to the majority group. When regression equations were adjusted for unreliability of the predictors, the observed differences in intercepts were reduced or eliminated. No prediction bias was observed against the minority groups.  相似文献

本研究开发了两种新的适用于多级评分项目的多维计算机化自适应测验(PMCAT)的选题策略——修正的连续熵(RCEM)和修正的后验期望KL信息(MKB)方法,并与以往PMCAT的选题策略进行了对比研究。Monte Carlo实验结果表明:两种新开发的选题策略比原方法估计精度更高,并且RCEM方法在所有选题策略中曝光率最低。新开发的选题策略具有较理想的估计精度和曝光控制效果,为PMCAT在实践中的应用提供了新的方法支持。  相似文献

CD-CAT是CDA同CAT的相结合的产物,适用于课堂教学,是教师补救教学、学生自我学习的重要工具。作为CD-CAT重要组成部分的初始阶段项目选取方法是影响测验判准率的重要因素。本文基于现有研究和CDA的项目区分度提出了四种新的初始阶段项目选取方法:CTTID法、CDI法、CTTIDR*法和CDIR*法。通过模拟研究发现,在定长的CD-CAT下,题库质量是HD-HV下,初始阶段结束时,CTTIDR*法的PCCR比现有的T阵法高了.2999,比PWKL高了.1707,其它题库下趋势相同。整个测验结束时CTTIDR*法的判准率仍然是最高的。在变长的CD-CAT下,最大后验概率大于.7、.8、.9下,CTTIDR*法的被试平均测验长度比T阵法分别缩短了2.6170、2.2347、1.7470道题。  相似文献

The present study investigated mate preferences for five different levels of relationship involvement—marriage, serious relationship, falling in love, casual sex, and sexual fantasies–among individuals of 20, 30, 40, 50, and 60 years of age. Consistent with an evolutionary perspective, men preferred mates who were higher in physical attractiveness than themselves, whereas women preferred mates who were higher in income, education, self–confidence, intelligence, dominance, and social position than themselves. The lower the level of relationship involvement, the lower were the preferred levels of education, physical attractiveness, and, particularly for males, preferred intelligence in comparison to oneself. For sexual fantasies, men and women preferred mates who were higher in physical attractiveness than those they preferred for real partners. There were few age differences in mate preferences, although older individuals set higher standards for a potential mate’s education.  相似文献

The acculturation of international people in a midwestern university was studied. Acculturation variables of perceived prejudice, observance of cultural practices and social ties, and language usage were measured. Africans, Asians, and South Americans were significantly less acculturated than were Europeans. Significant differences were also found for permanent versus nonpermanent United States residence status, length of residence in the United States, and religion. Themes derived from open-ended responses showed that participants related their identity to the values, religion, physical appearance, and language of their national origins. Emerging themes also suggested a reciprocity of acceptance and animosity in the dominant-minority intergroup relations.  相似文献

International Perspectives on the Legal Environment for Selection   总被引:4,自引:4,他引:0  
Perspectives from 22 countries on aspects of the legal environment for selection are presented in this article. Issues addressed include (a) whether there are racial/ethnic/religious subgroups viewed as "disadvantaged," (b) whether research documents mean differences between groups on individual difference measures relevant to job performance, (c) whether there are laws prohibiting discrimination against specific groups, (d) the evidence required to make and refute a claim of discrimination, (e) the consequences of violation of the laws, (f) whether particular selection methods are limited or banned, (g) whether preferential treatment of members of disadvantaged groups is permitted, and (h) whether the practice of industrial and organizational psychology has been affected by the legal environment.  相似文献

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) Rubin, D. B. and Thomas, N. 1996. Matching using estimated propensity scores, relating theory to practice.. Biometrics, 52: 249264. [Crossref], [PubMed], [Web of Science ®] [Google Scholar] show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs.  相似文献

This paper explores the relationship between personality, IQ, gender, beliefs about intelligence, and preference for assessment methods at university in 3 separate studies. Study 1 ( N = 367) examined attitudes toward examinations (ATE) and attitudes toward continuous assessment (ATCA) using specific assignments with regard to subjectively assessed intelligence (SAI), entity and incremental beliefs about intelligence (BAI), just-world beliefs, and gender. Studies 2 ( N = 120) and 3 ( N = 93) found significant and negative associations between neuroticism and preference for both essay-type and oral exams. IQ was positively and significantly related to preference for multiple-choice exams. Study 3 tested the relationship of preference for assessment methods with academic performance. Results indicated that preferences are associated with individual differences, rather than academic performance. Findings are discussed in terms of the advantages and disadvantages of introducing alternative methods of student assessment at the university level.  相似文献

Approximately 30% of suicides in New York City are the result of jumping from a height. After describing jumping suicides and jumping sites, we used polychotomous logistic regression to compare the characteristics of suicides by jumping to those of individuals committing suicide by hanging, ingestion, or shooting. Method used was significantly associated with sociodemographics, occupation, and mental health status, even after adjustment for individual access to the means of committing suicide. Our finding of an independent association between personal characteristics and method used provides strong evidence for the hypothesis that controlling access to an agent of suicide can influence overall suicide rates, at least in the short term. Study results support the introduction of preventive programs to control access to commonly employed agents of suicide.  相似文献
