This study examined the application of framing theory in issues management. Using case study methodology, the researchers analyzed message frames used by Kraft Foods in its public response to the obesity crisis, how the Kraft frames were reported by the media and whether Kraft's approach might help define effective framing and issues management practices in public relations. The study suggested that framing was indeed useful in Kraft's attempt to manage the issue of obesity.  相似文献

The authors sought to assess the perception of risks for coronary heart disease (CHD) in college men and women. They surveyed 470 undergraduates from 2 major 4-year institutions who completed a questionnaire that measured perceived risks for heart disease. Sixty-eight percent of the respondents rated their risks as lower or much lower than those of their peers, indicating a clear optimistic bias. The research also revealed that the students who exercised regularly rated their risk of coronary disease lower than those who did not do so. In addition, women perceived a number of risk markers to be more potent or causative factors than men did. A significant number of participants did not comprehend commonly understood causal relationships associated with heart disease risk. The findings in this preliminary investigation suggest that college men and women do not accurately perceive their risks for developing heart disease.  相似文献

The Great Plains Rural Collaborative project explored rural poverty through the experiences of people living at or below 185% of poverty. Researchers collected information through qualitative and quantitative research methods. They designed focus group questions to identify obstacles rural families face when trying to access economic opportunities, social networks, and services and supports. The article highlights the salient findings.  相似文献

Because of their mouthing behaviors, children have a higher potential for exposure to available chemicals through the nondietary ingestion route; thus, frequency of hand-to-mouth activity is an important variable for exposure assessments. Such data are limited and difficult to collect. Few published studies report such information, and the studies that have been conducted used different data collection approaches (e.g., videography versus real-time observation), data analysis and reporting methods, ages of children, locations, and even definitions of "mouthing." For this article, hand-to-mouth frequency data were gathered from 9 available studies representing 429 subjects and more than 2,000 hours of behavior observation. A meta-analysis was conducted to study differences in hand-to-mouth frequency based on study, age group, gender, and location (indoor vs. outdoor), to fit variability and uncertainty distributions that can be used in probabilistic exposure assessments, and to identify any data gaps. Results of this analysis indicate that age and location are important for hand-to-mouth frequency, but study and gender are not. As age increases, both indoor and outdoor hand-to-mouth frequencies decrease. Hand-to-mouth behavior is significantly greater indoors than outdoors. For both indoor and outdoor hand-to-mouth frequencies, interpersonal, and intra-personal variability are approximately 60% and approximately 30%, respectively. The variance difference among different studies is much bigger than its mean, indicating that different studies with different methodologies have similar central values. Weibull distributions best fit the observed data for the different variables considered and are presented in this article by study, age group, and location. Average indoor hand-to-mouth behavior ranged from 6.7 to 28.0 contacts/hour, with the lowest value corresponding to the 6 to <11 year olds and the highest value corresponding to the 3 to <6 month olds. Average outdoor hand-to-mouth frequency ranged from 2.9 to 14.5 contacts/hour, with the lowest value corresponding to the 6 to <11 year olds and the highest value corresponding to the 6 to <12 month olds. The analysis highlights the need for additional hand-to-mouth data for the <3 months, 3 to <6 months, and 3 to <6 year age groups using standardized collection and analysis because of lack of data or high uncertainty in available data. This is the first publication to report Weibull distributions as the best fitting distribution for hand-to-mouth frequency; using the best fitting exposure factor distribution will help improve estimates of exposure. The analyses also represent a first comprehensive effort to fit hand-to-mouth frequency variability and uncertainty distributions by indoor/outdoor location and by age groups, using the new standard set of age groups recommended by the U.S. Environmental Protection Agency for assessing childhood exposures. Thus, the data presented in this article can be used to update the U.S. EPA's Child-Specific Exposure Factors Handbook and to improve estimates of nondietary ingestion in probabilistic exposure modeling.  相似文献

In this essay we identify and discuss some of the challenges currently faced by the Pacific Sociological Association (PSA) related to its governance. The PSA is not unlike other regional associations and faces similar challenges. The rapid growth in membership for the association has repeatedly placed strains on the governance structure, particularly on the office of the Executive Director. The formal organization of governance has not always matched the actual ways in which governing is carried out, almost entirely by volunteers. Although there is growth, there is also significant turnover in members from year to year and this presents a challenge for maintaining an active, vibrant organization. The governing structure of elected committees and officers has not changed with membership growth but the number of standing committees has increased dramatically, spreading the volunteer membership thin. To meet these challenges, we make several suggestions. We argue for the importance of maintaining a stable membership; that the PSA should continue its work to formally define roles and positions including a restructuring of its committees; and an emphasis should be placed on providing an intellectual home for the members of the PSA. We elaborate on these responses to the challenges faced by the PSA and suggest considerations for the association as it moves into the final decade of its first 100 years.  相似文献

When reflecting on their experiences with children from lesbian‐parented families, 64 childcare centre directors in Victoria, Australia indicated that explicit programs, policies or resources of support were absent in their centres. Importantly, participants' pre‐ and post‐professional education either ignored or superficially addressed lesbian matters. This may explain the limited nature of inclusion of lesbian matters in early childhood education. Of note, is the pervasive nature of ‘truths’ upheld by educators. That is, in the Foucauldian sense these educators perceived lesbian families as being the ‘same’ as heterosexual families. Despite the considerable shifts in professional attitudes and ‘truths’ about sexuality, the Foucauldian silences were being reinforced in everyday practice as evidenced by the reference to ‘raised eyebrows’ by participants when this silence about sexuality was threatened.  相似文献

This study examined associations between substance use, family functioning, and self-image among four ethnic adolescent groups. Three thousand three hundred and fifteen 8th and 9th grade students were recruited from 10 schools in Los Angeles County. Participants completed a paper-and-pencil survey regarding their alcohol and marijuana use, along with their perceived family functioning and self-image and other demographic variables. Ordinal logistic regression was performed to examine associations. Results indicated that both family functioning and self-image were significantly associated with alcohol and marijuana use. Those who scored lower on family functioning and self-image were at increased risk for substance use. Furthermore, students who scored low in both family functioning and self-image were about twice as likely to report using alcohol.  相似文献

In this article, we reviewed results of research on near-death experiences (NDEs) over the past 3 decades and examined the effect of viewing the hour-long 2002 BBC documentary The Day I Died: The Mind, the Brain, and Near-Death Experiences on accurate knowledge about near-death experiences among advanced undergraduates at a southwestern university. In a quasi-experimental research design, the experimental group completed a 20-item questionnaire before and after viewing the documentary (n = 66; 45 females, 21 males), and the waitlist control group completed the questionnaire as pre- and posttest before viewing the documentary (n = 39; 36 female, 3 male). The two groups' scores at pretest were not significantly different (p > .05). Group by occasion repeated measures ANOVA revealed the experimental group's posttest scores moved significantly in the direction of correctness with a large effect size (p < .001; eta2 = .56), whereas waitlist control group posttest scores remained similar to pretest scores. We discuss two exceptions to the effectiveness of the documentary and recommendations for educators using it as well as for future research.  相似文献

Concern over the impending retirement of several top-level managers led a county agency to engage in efforts aimed at more efficient succession management. Administrators developed plans to prevent the loss of invaluable knowledge and wisdom accompanying retirement of experienced agency leaders. The agency's Director of Finance (DoF) was one of the first key figures projected to retire, and a succession plan was implemented to transfer his knowledge for use after his departure. The knowledge transfer process involved three stages, including: (1) employing the DoF as teacher, having him develop curricula and conduct trainings; (2) engaging the DoF as mentor, allowing an existing staff member and the DoF's successor to shadow and be coached by the DoF; and (3) developing a knowledge management system that could be used after the DoF departed. This case study describes the knowledge transfer process and experiences shared by the DoF and this agency.  相似文献
