The authors examined cohabiting union formation processes by analyzing in‐depth interview data collected from 30 individuals in cohabiting relationships: 15 low‐income Black mothers of adolescents and their partners. Prior research suggests that cohabiting union formation is a gradual, nondeliberative process. In contrast, most couples in this study described a gradual but highly deliberative process. Mothers focused primarily on vetting their partners to ensure child well‐being and less on when and how their partners officially came to live with them, a process the authors call vetting and letting. Mothers delineated 4 strategies to ensure their child's well‐being when vetting their partners, and their partners reported that they understood the importance of participating in this process. The authors argue that vetting and letting is a child‐centered family formation process, not a partner‐centered union formation process, and that cohabiting union processes may vary substantially by subpopulation.  相似文献

Near misses are widely believed to encourage future play, even in games of chance where the probability of winning remains constant from trial to trial. Some commercial gambling systems, particularly instant lotteries and slot machines, are contrived to ensure a higher frequency of near misses than would be expected by chance alone. Theoretical interpretations and relevant experiments are examined. A distinction is drawn between possible short-term and longer-term effects of manipulating the rate of occurrence of near misses.The first four experiments reported in the text were carried out by Amanda Shattock, supported by a Grant from the Social Science Research Council.  相似文献

Summary.  In many areas of pharmaceutical research, there has been increasing use of categorical data and more specifically ordinal responses. In many cases, complex models are required to account for different types of dependences among the responses. The clinical trial that is considered here involved patients who were required to remain in a particular state to enable the doctors to examine their heart. The aim of this trial was to study the relationship between the dose of the drug administered and the time that was spent by the patient in the state permitting examination. The patient's state was measured every second by a continuous Doppler signal which was categorized by the doctors into one of four ordered categories. Hence, the response consisted of repeated ordinal series. These series were of different lengths because the drug effect wore off faster (or slower) on certain patients depending on the drug dose administered and the infusion rate, and therefore the length of drug administration. A general method for generating new ordinal distributions is presented which is sufficiently flexible to handle unbalanced ordinal repeated measurements. It consists of obtaining a cumulative mixture distribution from a Laplace transform and introducing into it the integrated intensity of a binary logistic, continuation ratio or proportional odds model. Then, a multivariate distribution is constructed by a procedure that is similar to the updating process of the Kalman filter. Several types of history dependences are proposed.  相似文献

The study of the relationship between group membership and identity has been central to symbolic interaction. This paper describes one instance of problematic identity, that experienced by members of the newly established academic discipline of general practice. 1By outlining their dilemma as ‘marginal men’ to both service doctors and other academics within the medical faculty,2 attention is focussed upon the strained intraprofessional relationships when core tasks—in this case teaching and service work—are allocated very different values.  相似文献

Following Viraswami and Reid (1996), higher-order results under model misspecification are obtained for the likelihood-ratio statistic and the adjusted likelihood-ratio statistic, for the case of a scalar parameter. An improved version of the adjusted likelihood-ratio statistic is suggested.  相似文献

Despite calls for increased attention to the experiences of transgender people, scientific understanding of the stigma and discrimination this population experiences is limited. The authors integrate minority stress and marital advantage perspectives to assess marital status differences in transgender‐related perceived discrimination among transgender people in multiple life domains: the workplace, family, health care, and public accommodations. They analyze one of the first and most comprehensive large‐scale samples of transgender people in the United States (N = 4,286), the National Transgender Discrimination Survey. They find that married transgender respondents tend to report lower levels of perceived discrimination than their cohabiting and previously married transgender counterparts. Married transgender respondents do not, however, report lower levels of perceived discrimination than their never married counterparts, once all covariates are accounted for. These marital status differences appear primarily among transwomen but not transmen. Economic resources account for some, but not all, of these differences.  相似文献
