Many proposed methods for analyzing clustered ordinal data focus on the regression model and consider the association structure within a cluster as a nuisance. However, the association structure is often of equal interest—for example, temporal association in longitudinal studies and association between responses to similar questions in a survey. We discuss the use, appropriateness, and interpretability of various latent variable and Markov models for the association structure and propose a new structure that exploits the ordinality of the response. The models are illustrated with a study concerning opinions regarding government spending and an analysis of stability and change in teenage marijuana use over time, where we reveal different behavioral patterns for boys and girls through a comprehensive investigation of individual response profiles.  相似文献

This study investigated factors affecting the adjustment of parentally bereaved children by reviewing existing literature and comparing it to observations made by professional social workers. Interviewees had between 1 1/2 and 22 years of experience in counseling bereaved children. The specific factors examined were age and sex of the bereaved child, circumstances of the death, and adjustment of remaining caregiver. Participants (n = 5) responded to an interview instrument specifically designed for this study which contained seven in-depth, open-ended questions. Participants’ replies were mostly in accordance with the literature, but also generated some new perspectives that had not been previously considered for this study and had not appeared in the literature. This study has implications for practice with parentally bereaved children and their surviving caregivers.Rebecca M.

A review of the sociological research about gender and migration shows the substantial ways in which gender fundamentally organizes the social relations and structures influencing the causes and consequences of migration. Yet, although a significant sociological research has emerged on gender and migration in the last three decades, studies are not evenly distributed across the discipline. In this article, we map the recent intellectual history of gender and migration in the field of sociology and then systematically assess the extent to which studies on engendering migration have appeared in four widely read journals of sociology (American Journal of Sociology, American Sociological Review, Demography, and Social Forces). We follow with a discussion of these studies, and in our conclusions, we consider how future gender and migration scholarship in sociology might evolve more equitably.  相似文献

东西方文化维度的不同决定了组织中激励的方式各有差异。研究具有中国文化特质的“关系”与“面子”,理解“自我概念”“角色完成”“领导者的责任”“长期目标”“和谐关系”“满足感与平等感”等具体概念的东西方差异,建立修改后的综合分析模型,该模型表明虽然禀性匹配对于西方文化背景下的工作激励过程很重要,但在中国的领导者与员工之间,“关系”和“面子”更为重要。  相似文献

This study seeks to explore transnational communication among migrants of the Irish diaspora through an examination of the Orange Order's networks. It draws upon rare local and district records and press accounts to explain the migratory links and social worlds of Orange emigrants from Ulster. The substance of the study echoes the findings of Canadian historians who have much richer records than exist in the public domain in Britain. It demonstrates how Orangemen in Ireland came to recognise the diasporic dimension of their movement, and how members used the Order to negotiate some of the pathways of migration that were an important feature of their lives, and in the lives of the working class more generally. The essay generally seeks to demonstrate that the Orange Order acted as a network of friendship, camaraderie and support for emigrants and immigrants in the British World in the late nineteenth and early twentieth centuries.  相似文献

We describe and illustrate methodology for comparing networks from diverse settings. Our empirical base consists of 42 networks from four kinds of species (humans, nonhuman primates, nonprimate mammals, and birds) and covering distinct types of relations such as influence, grooming, and agonistic encounters. The general problem is to determine whether networks are similarly structured despite their surface differences. The methodology we propose is generally applicable to the characterization and comparison of network–level social structures across multiple settings, such as different organizations, communities, or social groups, and to the examination of sources of variability in network structure. We first fit a p* model (Wasserman and Pattison 1996) to each network to obtain estimates for effects of six structural properties on the probability of the graph. We then calculate predicted tie probabilities for each network, using both its own parameter estimates and the estimates from every other network in the collection. Comparison is based on the similarity between sets of predicted tie probabilities. We then use correspondence analysis to represent the similarities among all 42 networks and interpret the resulting configuration using information about the species and relations involved. Results show that similarities among the networks are due more to the kind of relation than to the kind of animal.  相似文献
