This study examined effects of local economic conditions on individuals' attitudes toward midpregnancy marriages using an experimental vignette method. Adults (N = 460) were each shown two vignettes about a hypothetical couple expecting a baby; within each vignette pair, vignettes randomly varied as to whether the couple lived in a community that had recently experienced job losses or had stable employment. Respondents indicated if the couple should and will get married before the baby's birth. Results showed that worse local economic conditions led people to believe that marriage would be less common. Among more socioeconomically disadvantaged respondents, if the hypothetical couple lived in a community with job loss, fewer respondents also thought that the couple should marry. In contrast, among more socioeconomically advantaged respondents, slightly more respondents thought that the couple should marry. When economic conditions worsen, low‐socioeconomic‐status individuals may believe that financial prerequisites for marriage become harder to meet.  相似文献

Space weather describes the way in which the Sun, and conditions in space more generally, impact human activity and technology both in space and on the ground. It is now well understood that space weather represents a significant threat to infrastructure resilience, and is a source of risk that is wide‐ranging in its impact and the pathways by which this impact may occur. Although space weather is growing rapidly as a field, work rigorously assessing the overall economic cost of space weather appears to be in its infancy. Here, we provide an initial literature review to gather and assess the quality of any published assessments of space weather impacts and socioeconomic studies. Generally speaking, there is a good volume of scientific peer‐reviewed literature detailing the likelihood and statistics of different types of space weather phenomena. These phenomena all typically exhibit “power‐law” behavior in their severity. The literature on documented impacts is not as extensive, with many case studies, but few statistical studies. The literature on the economic impacts of space weather is rather sparse and not as well developed when compared to the other sections, most probably due to the somewhat limited data that are available from end‐users. The major risk is attached to power distribution systems and there is disagreement as to the severity of the technological footprint. This strongly controls the economic impact. Consequently, urgent work is required to better quantify the risk of future space weather events.  相似文献

This study develops a multi‐level approach on frontline interactions in the public sector. Previous research suggests that detailed analyses of frontline interactions are essential to our understanding of how welfare services take shape when policies and rules are applied and negotiated in individual cases. The dynamics and performances of real‐time interactions have, however, rarely been analyzed as such. This study shows how the methods developed in the field of Conversation Analysis can contribute to this research. Our multi‐level approach integrates analyses of the policy‐ and institutional transformations that shape conditions for frontline interactions; and analyses of how policies and rules are evoked, negotiated and reshaped in the turn‐by‐turn organization and performances of interaction. The approach is applied on an analysis of how rules regarding financial aid are applied in an authority highly affected by changes in welfare policy towards standardization and detailed regulations. The empirical case is the Swedish Board for Study Support. The empirical study includes analyses of documents, interviews and analyses of taped telephone conversations. The study shows how institutional arrangements of standardization, detailed regulations, monitoring and depersonalization, structure the frontline work and shape narrow frames for officials' discretion in interactions with clients. The study also shows how rules are invoked and negotiated in recurrent practices in the interaction: in the careful design of decisions; in the investigations of alternatives and exceptions from the rules in order to find solutions to the client's problems. The analyses of concrete interactional practices clearly indicate that also a rule‐governed work dominated by task discretion involves recurrent negotiations, flexibility and local policy‐making.  相似文献

From 1960 through 1972, Dr. Eugene Saenger oversaw the experimental administration of lethal and near‐lethal doses of radiation to hospital patients at the University of Cincinnati. These experiments were funded by the US Department of Defense, and were specifically designed to acquire military information on the effects of radiation in combat soldiers. Although Saenger's research was terminated after public exposure in 1971, a full and detailed account has not been available until now. The account provided by the President's Advisory Committee on Human Radiation Experiments (ACHRE) in their Final Report of 1995 was incomplete. Our account is based on a reanalysis of all the material available to ACHRE, including highly critical peer reviews by U.C. faculty members. We also present, for the first time, several case histories taken from the medical records of Dr. Saenger's subjects.  相似文献

We develop a prioritization framework for foodborne risks that considers public health impact as well as three other factors (market impact, consumer risk acceptance and perception, and social sensitivity). Canadian case studies are presented for six pathogen‐food combinations: Campylobacter spp. in chicken; Salmonella spp. in chicken and spinach; Escherichia coli O157 in spinach and beef; and Listeria monocytogenes in ready‐to‐eat meats. Public health impact is measured by disability‐adjusted life years and the cost of illness. Market impact is quantified by the economic importance of the domestic market. Likert‐type scales are used to capture consumer perception and acceptance of risk and social sensitivity to impacts on vulnerable consumer groups and industries. Risk ranking is facilitated through the development of a knowledge database presented in the format of info cards and the use of multicriteria decision analysis (MCDA) to aggregate the four factors. Three scenarios representing different stakeholders illustrate the use of MCDA to arrive at rankings of pathogen‐food combinations that reflect different criteria weights. The framework provides a flexible instrument to support policymakers in complex risk prioritization decision making when different stakeholder groups are involved and when multiple pathogen‐food combinations are compared.  相似文献

To address the persistent problems of foodborne and zoonotic disease, public health officials worldwide face difficult choices about how to best allocate limited resources and target interventions to reduce morbidity and mortality. Data‐driven approaches to informing these decisions have been developed in a number of countries. Integrated comparative frameworks generally share three methodological components: estimating incidence of acute illnesses, chronic sequelae, and mortality; attributing pathogen‐specific illnesses to foods; and calculating integrated measures of disease burden such as cost of illness, willingness to pay, and health‐adjusted life years (HALYs). To discuss the similarities and differences in these approaches, to seek consensus on principles, and to improve international collaboration, the E.U. MED‐VET‐NET and the U.S.‐based Food Safety Research Consortium organized an international conference convened in Berlin, Germany, on July 19–21, 2006. This article draws in part on the deliberations of the conference and discusses general principles, data needs, methodological issues and challenges, and future research needs pertinent to objective data‐driven analyses and their potential use for priority setting of foodborne and zoonotic pathogens in public health policy.  相似文献

This article summarizes the results of a qualitative study of career transition experiences of middle‐aged male scientists and engineers in the current socioeconomic environment in the United States. The study addresses the effects of the transitions from psychosocial perspectives. The authors selected participants from research organizations, industry, and academic fields. The authors used a narrative approach to collect data and analyzed the data using a grounded theory approach. The results suggest that the major factors that describe the dynamics in the career transition experiences are personhood, relationships, lifestyle, and workplace environment. The findings and their implications in developing coping skills and counseling strategies are discussed.  相似文献

This article examines whether market competition affects treatment expenditure and health outcomes of stroke and cardiac treatment in Taiwan. Our measure of treatment expenditure is the hospital expenditure paid at the index admission (short term) and the sum of inpatient and outpatient expenditures paid in the subsequent year (long term). Our measure of health outcome is the probability of death in 1 and 12 months after the hospital's discharge. Our measure of competition follows the method developed by Kessler and McClellan that calculates the Herfindal index based on the predicted patient flows using exogenous variables (e.g., traveling distance to hospitals). Using data of patients hospitalized for new stroke and cardiac treatment between 1997 and 2001 in Taiwan, we find that an increase of market competition results in an insignificant impact on a patient's mortality. In terms of treatment expenditure, our results indicate that hospitals facing more competition incur higher expenditures, either the short‐ or long‐term expenditure. Finally, we find evidence showing that an increase of treatment expenditure at admission is due to a raise of length of stay and treatment intensity per day as well as the usage of expensive equipment.
