This article addresses itself to issues in the socialization of young people to residential mobility orientations. Our conceptual framework emphasizes the importance of social context and active experience in the development of these orientations. Data from samples of youth from sixth to twelfth grades show them to have reasonable, if slightly conservative, mobility expectations. Other findings in the paper are consistent with the importance of social location and interpersonal relationships in youth socialization.The research on which this paper was based was supported by National Science Foundation Grant GS-39779. An earlier version of the paper was presented at the annual meeting of the Population Association of America, April 1974.

Because the stakes in health care are high, physician executives are challenged to meet high expectations set by their CEOs and boards. These may be unrealistic--for example, demanding that physician executives possess expertise in finance or strategic planning. Job stresses for physician executives are specific to the role, but are not unlike those faced by other senior executives. It's a fact that professionals leave jobs for any number of reasons; sometimes, not through their own choice or fault. Thus, every time a physician executive leaves a job, it should not be characterized as "being fired," and not every job-leaving should be taken as a failure. Accept that you may make mistakes while doing the best job you can. Rely on your own value system and integrity to see you through.  相似文献

Casual sex is common during the emerging adult life course stage, but little research has taken a person-centered approach to investigate if casual sexual behavior influences sexually transmitted infection (STI) rates. Using a nationally representative sample and latent class analysis, results showed three distinctive latent classes. Abstainers were the least likely to have an STI, followed by the casual sex experienced, and then the casual sex risk-takers. Once other covariates were included in the model, there was no significant difference between the abstainers and casual sex experienced classes. These results highlight the need for future research to include diverse samples of emerging adults.  相似文献

This study examined the reliability and validity of the Vulnerability Index-Service Prioritization Decision Assistance Tool (VI-SPDAT), a widely-used assessment of the health and social vulnerabilities and housing needs of individuals experiencing homelessness. Homeless Management Information System data were obtained for 1495 individuals who were administered the VI-SPDAT between 2014 and 2016. Subsamples were selected for reliability and validity assessments. Results suggest there are challenges to the reliability and validity of the VI-SPDAT in practical use. VI-SPDAT total scores did not significantly predict risk of return to homeless services, while type of housing was a significant predictor. Vulnerability assessment instruments have important implications for communities working to end homelessness by facilitating prioritization of scarce housing resources. Findings suggest that further testing and development of the VI-SPDAT is necessary.  相似文献

According to Federal Aviation Administration traffic predictions currently our Air Traffic Management (ATM) system is operating at 150 percent capacity; forecasting that within the next two decades, the traffic with increase to a staggering 250 percent [17]. This will require a major redesign of our system. Today's ATM system is complex. It is designed to safely, economically, and efficiently provide air traffic services through the cost-effective provision of facilities and seamless services in collaboration with multiple agents however, contrary the vision, the system is loosely integrated and is suffering tremendously from antiquated equipment and saturated airways. The new Next Generation (Next Gen) ATM system is designed to transform the current system into an agile, robust and responsive set of operations that are designed to safely manage the growing needs of the projected increasingly complex, diverse set of air transportation system users and massive projected worldwide traffic rates. This new revolutionary technology-centric system is dynamically complex and is much more sophisticated than it's soon to be predecessor. ATM system failures could yield large scale catastrophic consequences as it is a safety critical system. This work will attempt to describe complexity and the complex nature of the NextGen ATM system and Trajectory Based Operational. Complex human factors interactions within Next Gen will be analyzed using a proposed dual experimental approach designed to identify hazards, gaps and elicit emergent hazards that would not be visible if conducted in isolation. Suggestions will be made along with a proposal for future human factors research in the TBO safety critical Next Gen environment.  相似文献

Those who develop or influence Australian public policy impacting on the nonprofit sector rarely have adequate empirical research upon which to base their judgments. Giving Australia research evidence relevant to strengthening giving and volunteering is brought together in this article to inform policy options for government, nonprofit and philanthropic entities. It begins with consideration of research findings related to the capacity of those that give or volunteer and the implications these findings have for policy. Three key criteria are developed for assessing policies to strengthening giving and volunteering, behaviours that primarily assist nonprofit organisations – policies that build trust between those that give and the recipients of their gifts, policies that strengthen affiliation and policies that encourage planned giving.  相似文献

Multilevel modeling allows for the simultaneous analysis of data gathered at more than 1 unit of analysis (e.g., children nested in schools). It is often used to examine the effects of various contexts on individual differences in change. This paper promotes the application of multilevel models to longitudinal dyadic data in family research. By focusing on the dyad as context, researchers can examine within‐dyad change and begin to understand the interactive processes that constitute the relationship between partners. They can then frame questions about interdyad differences in within‐dyad change. We present several longitudinal models that researchers can use to examine the pattern of change within dyads, assess heterogeneity in change across dyads, and investigate cross‐partner effects on change. We comment on the implications of these models for family research.  相似文献

The giving of time and money, mainly to private nonprofit organisations is not trivial, but in Australia has been little studied. This article introduces a special issue of the Australian Journal of Social Issues which draws on data collected in the largest study of giving and volunteering conducted in Australia hitherto. It seeks to establish terminological guidelines and reviews past Australian research on giving and volunteering, arguing that there has been a disproportionate interest in volunteering. It seeks to put to rest some common myths about giving and explores whether the increase in giving and volunteering can be attributed to government policy. It concludes by introducing the other papers in the collection.  相似文献
