How do journalists leverage Twitter? Expressive and consumptive use of Twitter

This study examined factors that affect journalists’ Twitter use behaviors based on the framework of the theory of planned behavior (TPB). A survey of Korean journalists supported that TPB is a useful theoretical framework for understanding journalists’ Twitter use behaviors. This study found that three TPB variables – positive attitudes, subjective norm, and perceived behavioral control – are positively associated with journalists’ general Twitter use (i.e., time spent using Twitter). More importantly, beyond looking at journalists’ general Twitter use, this study expands the literature by distinguishing between expressive Twitter use (e.g., tweeting messages) and consumptive Twitter use (e.g., reading others’ tweets). Results showed that journalists’ attitudes, subjective norms, and perceived behavioral controls were associated differently depending on patterns of expressive and consumptive Twitter usage. Given the role of professional journalists in society, their ways of using Twitter may have a profound impact on the ecology of journalism. Contributing to the literature of the theory of planned behavior by extending its explanatory power to professional journalists’ Twitter usage, the results of this study suggest that future research on journalists’ Twitter use should pay more attention to how Twitter is employed within the journalistic context.     

They Should Say “I Don't”: Norms About Midpregnancy Marriage and Job Loss

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.     

The Economic Impact of Space Weather: Where Do We Stand?

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.     

Childhood adversity,adult homelessness and the intergenerational transmission of risk: a population‐representative study of individuals in households with children

This study tested for associations between childhood adversity, adult homelessness and contexts of developmental risk in households with children. Data were drawn from the 2010 Washington State Behavioral Risk Factor Surveillance System, representative of the population of Washington State residents. Considering adults in households with children, those who experienced higher levels of childhood adversity were more likely to have experienced homelessness in adulthood. Meanwhile, a 10‐factor index of cumulative developmental risk was independently associated with childhood adversity and with adult homelessness. Adult homelessness appears to represent a circumstance through which past childhood adversities are brought forward and associated with contexts of developmental risk for subsequent generations of children.     

A little too much of the buchenwald touch? Military radiation research at the university of Cincinnati, 1960–1972

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.     

Integrated Approaches for the Public Health Prioritization of Foodborne and Zoonotic Pathogens

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.     

Midlife Career Transitions of Men Who Are Scientists and Engineers: A Narrative Study

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.     

THE ROLE OF HOSPITAL COMPETITION ON TREATMENT EXPENDITURE AND OUTCOME: EVIDENCE FROM STROKE AND CARDIAC TREATMENT IN TAIWAN

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.
