Asthma patients' health status may be especially sensitive to some types of air pollution, but the evidence on this is mixed. We explore the effects of ground-level ozone on asthma patient's activities, breaking apart the usual aggregated category of leisure into indoor and outdoor activities, and differentiating those by whether the activities were active or inactive. Applying the semiparametric censored estimation method we demonstrate that even though the period over which activities were observed was relatively low in ozone levels, there is a significant impact of ozone on a few activities. The (non-ozone) economic and demographic variables in the model play significant roles in explaining the allocation of time among seven activities, suggesting the suitability of the approach for other household decision-making contexts. 相似文献

Drawing on interviews with more than 80 scientists on two university campuses, we create a typology that offers insights into how transformations in the nature and locus of life science innovation influence academic careers and work practices. Our analyses suggest that a strong outcome of increased academic concern with research commercialization is the appearance of new fault lines among faculty, between faculty and students, and even between scientists' interests and those of their institutions. We argue that life science commercialization is driven by a mix of new funding opportunities, changing institutional mandates for universities, and novel research technologies that bring basic research and product development into much closer contact. The rise of patenting and commercially motivated technology transfer on U.S. campuses is altering faculty work practices and relationships, while transforming the criteria by which success is determined and rewards are allocated. Through close analysis of interviews with four researchers who typify a range of academic responses to commercialism, we demonstrate emerging patterns of conflict and agreement in faculty responses to commercial opportunities in the life sciences. 相似文献

To understand how oxidative stress contributes to aging and age-related diseases and to better evaluate the therapeutic effect of antioxidant drugs, it would be highly desirable to have a comprehensive and detailed readout of the types of oxidative damage that occur to proteins at a global or proteome level. In this Perspective, I examine how proteomics, defined here as the science of examining all proteins in an organelle, cell, or tissue in the context of biological phenomena, can be used to provide molecular details of mitochondrial protein oxidative damage. Specifically, I discuss approaches that combine knowledge of the mitochondrial proteome with newer mass spectrometry-based techniques that are capable of identifying proteins and sites of oxidative modification in a high-throughput manner. 相似文献

Conclusions In the twenty years since the publication of What Do Unions Do?, employee benefits and contingent forms of non-wage compensation have increased in importance and scope in human resources
and industrial relations practice and policy. Nevertheless, Freeman and Medoff’s (1984) seminal work, and the associated research
in Freeman (1981, 1985), has stood the test of time. The theoretical and empirical agenda for research on unions and non-wage
forms of compensation established in those works continues to be the leading framework for conceptualizing and analyzing this
important issue. 相似文献

All family members interviewed suffered from chronic posttraumatic stress disorder 5 or more years after an infant kidnapping. Psychiatric nurses should routinely assess for secondary victimization related to any type of traumatic stressor. Nurses should refer parents and families to materials available from the National Center for Missing and Exploited Children (NCMEC) (http://www.missingkids.com/). 相似文献

In evaluating family preservation services, it is important not only to study the service outcomes and the family characteristics, but also what actually happens during the treatment. This requires a program model. This article describes how a program model works, prescribes how workers should carry it out, and describes how researchers should measure the program's characteristics. The authors use data from Families First in The Netherlands to test the model. Results show that the method of the program meets the specified characteristics. The results are important for treatment, policy, education, and evaluation research. 相似文献
