This article analyzes variations in interaction with non‐coresident adult kin based on comparable cross‐national surveys conducted in 2001 in 27 countries. The two main dimensions of kin contact are considered: (1) overall levels and (2) the relative emphasis given to contacts with primary kin (parents, adult children, siblings) and secondary kin (aunts, cousins, in‐laws). Age‐adjusted variations in kin contact between countries are much greater than those within countries. These results do not confirm the commonly hypothesized existence of well‐defined family system boundaries in Europe arising from historical factors. The similarity of patterns of countries outside Europe with European countries with which they have historical ties suggests cultural factors are important in explaining interaction with kin, whereas welfare regimes appear to have little explanatory value. Within Europe, kin contact levels are more strongly related to a north/south divide than to indicators of economic development or religiosity. The findings suggest that neither of the extreme assumptions—homogenizing pressures toward a nuclear family model or persistent well‐defined groupings arising from historical contexts—can be substantiated. Rather, there is a continuum in family behaviors over a substantial range, related to a number of explanatory factors. 相似文献

The transition to semiautonomous driving is set to considerably reduce road accident rates as human error is progressively removed from the driving task. Concurrently, autonomous capabilities will transform the transportation risk landscape and significantly disrupt the insurance industry. Semiautonomous vehicle (SAV) risks will begin to alternate between human error and technological susceptibilities. The evolving risk landscape will force a departure from traditional risk assessment approaches that rely on historical data to quantify insurable risks. This article investigates the risk structure of SAVs and employs a telematics‐based anomaly detection model to assess split risk profiles. An unsupervised multivariate Gaussian (MVG) based anomaly detection method is used to identify abnormal driving patterns based on accelerometer and GPS sensors of manually driven vehicles. Parameters are inferred for vehicles equipped with semiautonomous capabilities and the resulting split risk profile is determined. The MVG approach allows for the quantification of vehicle risks by the relative frequency and severity of observed anomalies and a location‐based risk analysis is performed for a more comprehensive assessment. This approach contributes to the challenge of quantifying SAV risks and the methods employed here can be applied to evolving data sources pertinent to SAVs. Utilizing the vast amounts of sensor‐generated data will enable insurers to proactively reassess the collective performances of both the artificial driving agent and human driver. 相似文献

AbstractObjective: To determine barriers and opportunities to health insurance enrollment among an undergraduate students at a large urban university. Participants: Participants were 31 college students enrolled in 4-year and community colleges in the City University of New York (CUNY), and six health services and insurance enrollment specialists who facilitate and assist in the health insurance enrollment process for CUNY students. Methods: Focus groups were conducted with students and in-depth interviews with key informants in May 2017. Results: The research revealed important insights into how students perceive and value insurance and yielded recommendations for the university to improve enrollment of its students. Conclusions: Many colleges can increase student enrollment in health insurance by informing and educating students about the process. Improving enrollment processes can increase insurance rates and improve student population health. 相似文献

One of the most significant positive approaches to the politics of climate change on the scale required by the problem is that of Giddens. This paper uncovers weaknesses in his argument and reveals motivational divergence for mitigation and energy security in both Canada and New Zealand, which is opposite to what occurred in Northern Europe that provided the basis for his analysis. This suggests that the response to climate change varies according to deeper cultural and geophysical structures. The paper also examines cost(risk)‐benefit analysis versus the precautionary principle, the directionality of political‐economic convergence with mitigation, and political partisanship concerning climate change. It documents the complexity of making near‐term economic opportunities converge with mitigation of distant harm. 相似文献

Military occupations are continually evolving in relation to the geopolitical changes of societies, their conflicts and conflict management strategies, and technological developments in military hardware and software. Military occupations studies undertaken by the academy have been key to informing government strategy towards the maintenance of functioning armed forces. Since the 1950s, such studies have prioritised ‘top‐down’ quantitative sociological methodologies. This paper reviews these studies and the role of the dominant Institutional/Occupational model. The paper then considers less influential ‘bottom up’ interpretive methodological studies of military occupations. It is suggested that the reliance on ‘top down’ modelling approaches has led to the paucity of studies describing the range and experiential detail of military occupations. The Military–Academy nexus, and the priorities of the discipline of sociology are suggested as reasons for this emphasis. 相似文献

The purpose of the study was to determine college women's (N = 405) reactions to body image and eating disorder research as well as predictors of negative reactions. Results suggested that the majority of women (94%) did not experience negative reactions and reported benefits to participating. Regression analyses revealed that disordered eating and poorer body esteem were predictive of negative reactions to research participation. Additional analyses were conducted to better understand those participants (N = 26; 6%) who reported negative reactions. Overall, results indicated that body image and eating disorder research is not distressing for the vast majority of participants. 相似文献

Gender Differences in Verbal Communication between Popular and Unpopular Children During an Interactive Task 总被引:1,自引:0,他引:1
This study investigated gender differences in communication effectiveness between popular and unpopular 5‐ to 7‐year‐old children. Because previous research suggests that there may be gender differences in how popular and unpopular children communicate with each other, 24 same‐gender pairs (each containing a popular and an unpopular child) were videotaped playing a game. Communication effectiveness was assessed by measuring the incidence of forms of speech associated with successful collaboration (questions, directives, and elaborations). Results revealed a popularity by gender interaction. Popular girls used a greater incidence of these forms of speech compared to unpopular girls. By contrast, there was no difference in the speech of popular and unpopular boys. Findings are interpreted in relation to the nature of the task and the characteristics of popular and unpopular children. 相似文献
