How publics’ active and passive communicative behaviors affect their tornado responses: An integration of STOPS and SMCC

During imminent threat crises, such as natural disasters, publics have minutes to decide how to respond after receiving a warning. This study advances understanding of publics’ crisis communicative and noncommunicative behaviors in the context of tornadoes through combining and extending two theories: the social-mediated crisis communication (SMCC) model and the situational theory of problem solving (STOPS). Findings from a survey of Southeast U.S. residents (n = 1,585) indicate that STOPS is internally consistent and accurate at measuring its intended outcomes of communicative action in problem solving. However, the STOPS measures do not have a significant relationship with the desirable outcome for imminent threat crisis communication: individuals following government’s protective action guidance about tornadoes. In comparison, the expanded SMCC model predicts individuals’ self-reported compliance. Finally, variables from the SMCC model and tornado-specific variables were integrated into the STOPS model to explain individuals’ communicative engagement. Implications for theory and public relations practice are discussed.     

Sex similarities in occupational status attainment: Are the results due to the restriction of the sample to employed women?

Research on sex differences in occupational attainment suggests that working men and working women attain essentially the same mean level of occupational attainment and do so through quite similar processes. A possible explanation for these similarities is that the sample of working women contains an overrepresentation of successful women, since women who can afford not to work will stay out of the labor force unless they find a job commensurate with their education. This we define as a censoring problem. By extending a technique developed by Heckman, we can estimate the structural parameters for all women, regardless of current employment status. This procedure allows us to assess the impact of the censoring problem on women's occupational attainment equations.     

Adolescent girls’ race/ethnic status, identities, and drive for thinness

Using data from 7272 adolescent US girls, we explore how girls’ race/ethnic group status affects their bodyweight, perceptions of overweight, and weight control practices. We hypothesize that a girl’s race/ethnic status influences her basic identity which in turn prompts her to adopt or reject a “drive for thinness.” After controlling for family and peer support, school engagement, family SES, maturation, and family structure, we find that girls’ race/ethnic status influences their susceptibility to the thinness ideals of mainstream culture. African American girls weigh more than Asian, Hispanic, or White girls, but at any given weight they perceive themselves as overweight and attempt to control their weight less. Asian American and White girls invest most in thinness dynamics. Some evidence also suggests girls from lower SES families are less driven to be thin. Our results affirm the utility of viewing material bodies as “situations” that are experienced and interpreted in accord with identity group relations and dynamics.

Local response to planning mandates. The prevalence and utilization of needs assessment by human service agencies.

Federal and state needs assessment mandates have traditionally been criticized both by their originators and by the local human service agencies that are required to conduct these studies as part of the planning process. This paper presents some preliminary evidence that local opposition to assessment may be shrinking as agencies gain a new appreciation for the varied uses of assessment information. Using data from a sample of Wisconsin agencies the prevalence of assessments between 1979 and 1980 is described and the conditions surrounding the practice of needs assessment are outlined. Particular attention is given to factors that affect the utilization of needs assessment results, including the characteristics of the sponsoring agency, the attributes of the study, and the structure of the assessment process.

The evaluation and monitoring of a Medicaid second surgical opinion program.

The evaluation of newly implemented and controversial programs often present real problems for the evaluator. When a program is accompanied by a legislatively mandated evaluation, the issues become even more acute. The evaluator, wanting to impact on policy, must strike a balance between the adherence to principles of scientific inquiry, yet be responsive to the needs of policymakers. This paper describes the evaluation and follow-up monitoring of a recently established second opinion program for Medicaid recipients. The program was to terminate in 17 months unless extended by the Wisconsin Legislature. The evaluation found, among other things, marked reductions in the use of surgical services after implementation of the second opinion program. Based in large part on the evaluation, the program was extended with a provision for continued monitoring. The paper discusses the factors that contributed to the evaluation having a major impact on the decision to extend the program.     

Leadership behavior and employee well-being: An integrated review and a future research agenda

Leadership behavior has a significant impact on employee behavior, performance and well-being. Extant theory and research on leadership behavior, however, has predominantly focused on employee performance, treating employee well-being (typically measured as job satisfaction) as a secondary outcome variable related to performance, rather than as an important outcome in and of itself. This qualitative state of the science review examines the process by which leadership behavior (i.e., change, relational, task, passive) affects employee well-being. We identify five mediator groupings (social-cognitive, motivational, affective, relational, identification), extend the criterion space for conceptualizing employee well-being (i.e., psychological: hedonic, eudaimonic, negative; and physical), examine the limited evidence for differential processes that underlie the leader behavior-employee well-being relationship and discuss theoretical and methodological problems inherent to the literature. We conclude by proposing a theoretical framework to guide a future research agenda on how, why and when leadership behavior impacts employee well-being.
