ABSTRACTGrandfamilies, family structures in which grandparent(s) co-reside with and assume a primary caregiving role for at least one grandchild, are increasingly common in the United States. This qualitative, exploratory study, informed by family communication patterns theory (FCPT), illuminated the reported communication beliefs and practices of grandparents who serve as primary caregiver to at least one grandchild. Hybrid thematic analysis, combining FCTP with inductive analysis, was used to analyze 21 semi-structured interviews with grandparents. Results yielded four themes describing grandparents’ reported communicative practices: creating opportunities for listening and dialogue, talking about emotion, emphasizing openness, and allowing questioning; and three themes describing the impact of second-chance parenting: increased resources, acquired wisdom, and matured emotionally. Implications for grandfamily communication research in light of hybrid analyses and FCPT are discussed. 相似文献

This study develops dose–response models for Ebolavirus using previously published data sets from the open literature. Two such articles were identified in which three different species of nonhuman primates were challenged by aerosolized Ebolavirus in order to study pathology and clinical disease progression. Dose groups were combined and pooled across each study in order to facilitate modeling. The endpoint of each experiment was death. The exponential and exact beta-Poisson models were fit to the data using maximum likelihood estimation. The exact beta-Poisson was deemed the recommended model because it more closely approximated the probability of response at low doses though both models provided a good fit. Although transmission is generally considered to be dominated by person-to-person contact, aerosolization is a possible route of exposure. If possible, this route of exposure could be particularly concerning for persons in occupational roles managing contaminated liquid wastes from patients being treated for Ebola infection and the wastewater community responsible for disinfection. Therefore, this study produces a necessary mathematical relationship between exposure dose and risk of death for the inhalation route of exposure that can support quantitative microbial risk assessment aimed at informing risk mitigation strategies including personal protection policies against occupational exposures. 相似文献

Background: The prevalence rates for both sarcopenia and erectile dysfunction (ED) gradually increase in middle-aged and elderly diabetic male population and they impair physical functioning, sexual functioning, and quality of life. The aim of the present study was to evaluate the sarcopenia in patients with diabetic ED.Methods: The study included 98 male patients with type II diabetes mellitus (DM) aged 18–80?years. Blood chemistry and hormone levels were obtained. The International Index of Erectile Function (IIEF-5) questionnaire was administered to the patients. The patients were divided into three groups according to the IIEF-5 score; a score of 5–10 points indicated severe ED, a score of 11–20 indicated moderate ED, and a score of 21–25 points indicated no ED. The muscle mass, handgrip strength, timed up and go test, upper mid-arm circumference, calf circumference, and body mass index were obtained. The statistical analysis was performed using MedCalc Statistical Software version 12.7.7. All parameters were compared between the three groups.Results: Of 98 patients included in the study, 84 patients had severe sarcopenia, 13 had moderate sarcopenia, while only one patient had normal muscle mass. The mean age was 56.59?±?11.46?years. When patients were divided into three groups according to IIEF-5 score, 38 had severe ED, 39 had moderate ED, and 21 had no ED. There was a significant difference between the three groups in terms of handgrip strength, timed up and go test scores, upper mid-arm circumference, and calf circumference (p?.05 for all).Conclusions: Although muscle mass remains unchanged, muscle strength and physical performance decrease in diabetic ED patients. Diabetic patients with severe and moderate ED have lower muscle strength and physical performance. 相似文献

This paper develops and examines a framework ofdownsizing processes at the organizational level. Itbuilds on previous frameworks and literature byintroducing new variables found to be important in a field study and by bringing empirical evidenceto bear on conceptual underpinnings related toorganizational downsizing and change. The frameworkdeveloped identifies two general approaches thatorganizations use when undergoing downsizing and redesign, aswell as patterns of activities and changes thataccompany them. Downsizing driving redesign involvesincremental and low-level change, and is associated with less communication and systematic analysis,narrow participation in change efforts, and lowermagnitude change in other organizational attributes.Redesign driving downsizing involves more fundamentalorganizational change, and is associated with high-levelchanges that involve restructuring, more communication,broad participation in change efforts, advancesystematic analysis, and the use of interorganizationalrelationships to further downsizing efforts. 相似文献

Differences in health between racial groups in the United States are significant and persistent. Many studies have documented these differences as a result of a variety of different social factors. An emerging emphasis is the impact of racism in its various forms on physical and mental health. Social stress theory conceptualizes racism as a social stresssor which can produce negative health consequences for racial minorities. This study uses binary logit and negative binomial regression models of four items from the 2004 Behavioral Risk Factor Surveillance System (BRFSS) to test social stress theory and examine the relationship between stress symptoms from perceived racism and overall health (N = 32,585). The effect of race on the experience of emotional and physical stress symptoms from racism is substantial. Furthermore, experiencing both emotional and physical stress from perceived racist treatment is an important factor in predicting the number of poor mental and physical health days, indicating that the experience of stress from perceived racism is related to overall poorer health. 相似文献

This paper describes the use and evaluation of application cards as a teaching tool designed to enhance students' abilities to apply knowledge learned in social work practice classes. Strengths and limitations of this tool as a means for enhancing students' application skills are discussed, based on qualitative and quantitative evaluative data. 相似文献

This paper uses data from the 1992 National Health and Social Life Survey to examine emotional satisfaction and physical pleasure from sex in intimate unions for adults in the U.S. Using perspectives from evolutionary biology and rational choice theory, we examine the effects of the following factors on emotional satisfaction and physical pleasure: time horizon expected for the relationship, sexual behavior within the relationship, and sexual exclusivity. We find a significant effect of measures for all 3 of these dimensions on emotional satisfaction with sex. For both men and women, time horizon and sexual exclusivity are more strongly tied to emotional satisfaction than they are to physical pleasure from sex, but sexual behavior has the same impact on emotional satisfaction as it does on physical pleasure. 相似文献

This article presents a methodology for assessment of the hazardous materials transport risk in a multicommodity, multiple origin-destination setting. The proposed risk assessment methodology was integrated with a Geographical Information System (GIS), which made large-scale implementation possible. A GIS-based model of the truck shipments of dangerous goods via the highway network of Quebec and Ontario was developed. Based on the origin and destination of each shipment, the risk associated with the routes that minimize (1) the transport distance, (2) the population exposure, (3) the expected number of people to be evacuated in case of an incident, and (4) the probability of an incident during transportation was evaluated. Using these assessments, a government agency can estimate the impact of alternative policies that could alter the carriers' route choices. A related issue is the spatial distribution of transport risk, because an unfair distribution is likely to cause public concern. Thus, an analysis of transport risk equity in the provinces of Quebec and Ontario is also provided. 相似文献
