Statistical methods have had a successful half-century in sociology, contributing to a greatly improved standard of scientific rigor in the discipline. I identify three overlapping postwar generations of statistical methods in sociology, based on the kinds of data they address. The first generation, which started in the late 1940s, deals with cross-tabulations and focuses on measures of association and log-linear models, perhaps the area of statistics to which sociology has contributed the most. The second generation, which began in the 1960s, deals with unit-level survey data and focuses on LISREL-type causal models and event-history analysis. The third generation, starting to emerge in the late 1980s, deals with data that do not fall easily into either of these categories, either because they have a different form, such as texts or narratives, or because dependence is a crucial aspect, as with spatial or social network data. There are many new challenges, and the area is ripe for statistical research; several major institutions have recently launched new initiatives in statistics and the social sciences.  相似文献

In this paper we analyze the explicit representation of fixed agenda social choice correspondences under different rationality assumptions (independence, Pareto optimality, etc.). It is well known that, under some of these assumptions, the existence of dictators, oligarchies or individuals with veto power can be proven ([6] and [10]); but only a partial characterization of the social choice set is obtained. We establish a relationship between the social choice set and the individuals' maximal sets, which explicitly describes a fixed agenda social choice correspondence that satisfies these rationality assumptions.

In New York State, all college students who were born on or after January 1, 1957, are required to show proof of immunity against measles, mumps, and rubella (MMR) before the 1st day of classes. Colleges have established immunization programs so that those students who do not have the required proof can be given the necessary injections. Often, our health service office does not have enough staff to administer the MMR shots during the registration period, resulting in long lines of students waiting to be immunized. In this article, the authors describe how one college used nursing students to assist with and enhance its immunization program. The 45 nursing students who participated in this project administered 694 injections over a 5-day period, They received credit from the nursing department for clinical time and all of the participants agree that the project was a success.  相似文献

Children (aged 9, 14, 19, and 24 months) were encouraged to use tools to achieve a demonstrated goal. Each tool was most efficiently applied when held by the handle with the thumb toward the head of the tool in a radial grip. The tools were presented at midline and oriented to the left and right on alternating trials, so the children who managed to grasp a tool in both orientations with the radial grip demonstrated planning of actions in advance. The tools included a spoon, hairbrush, toy hammer, and magnet; the goals were to feed one's self, feed another, brush one's hair, brush another's hair, hit pegs, and retrieve metal objects. Children were found to use more radial grips with the self‐directed tools (i.e., hairbrush‐to‐self and spoon‐to‐self), indicating that they could plan their actions better when directed toward the self than toward an external goal.  相似文献

Previous scholarship has demonstrated the importance of individual characteristics and structural context for understanding social capital formation. However, a developmental approach to social capital formation has, so far, been absent. In this study, I argue that social capital formation must be understood intergenerationally as well as structurally. Using hierarchical linear modeling, I investigate the hypothesized intergenerational transmission of social capital using Waves 1 and 2 of the National Longitudinal Study of Adolescent Health. The results show that, in addition to individual characteristics, neighborhood‐level factors, and school‐level variables, parental social capital is an important predictor of adolescent social capital. This study also suggests that the intergenerational transmission of social capital functions, in part, through family structure and that structural differences account for only a relatively small share of the variation in adolescent social capital. Potential explanations for these findings are discussed.  相似文献

Upwards of 200 studies over the past hundred years have reported on the relationship between public relations practitioners and journalists. However, no experiment has compared the group members’ perceptions when seeing their roles in action. Inspired by frameworks of social identity theory, intergroup deception, and the black sheep effect, we test how public relations practitioners and journalists respond to a crisis communication media interview. In our experiment, a company spokesperson either answers questions or engages in stereotypical “spin,” which journalists historically consider one of the most offensive public relations strategies. Results indicate that public relations practitioners align with journalists in their perceptions of a spokesperson’s trustworthiness and the organization’s trustworthiness across treatment conditions. Practitioners also manifest the black sheep effect, disliking their group representative engaging in deception. Furthermore, we explore whether the effects on perceptions of trustworthiness are moderated by psychological identification with their respective industry. Discussion concerns the theoretical and practical ramifications of the groups sharing ingroup affiliation, contrary to prevailing notions of acrimony.  相似文献

The Assets Coming Together for Youth project conducted a critical discourse analysis of mainstream media depictions of Jane-Finch to better understand the discursive strategies used to constitute urban youth. Although a substantive body of literature investigates the negative discourses, little analysis interrogates the nominally positive discourses deployed by mainstream media. The findings suggest that the sociopolitical significance of these nominally positive discourses may go uncontested and pose a challenge to communities advocating for policies to support urban youth development. These discourses are examined using governmentality theory to reveal how racialized narratives of individual triumph re/produce troubled communities.  相似文献
