Although burnout is a known risk for practitioners, some social work students may experience burnout in the classroom as a result of role conflict from balancing academics with employment. Higher rates of burnout occur in other disciplines in employed students, even higher than in professionals, because of the stress of shifting priorities between workplace and collegiate responsibilities. Employment can decrease collegiate engagement and academic competence and deter persistence to degree, all of which lead to the reduced competency associated with burnout. Additionally, physical and mental health factors are associated with role conflict, leading to a higher risk of burnout for employed students and resulting in burnout for social work students in the classroom even prior to becoming a practitioner.  相似文献

The goal of this paper is to understand the effect of family decision-making on the investment decisions of married men and women. Using data from the Survey of Consumer Finances, we investigate how the spouse’s relative control over financial resources in the household and the life-cycle stage affect the investment choices of married women and men. The results show that married women who have more control over the financial resources are less likely to invest their Defined Contribution Plans (DCPs) in risky assets. Also, women who are married to relatively older men are less likely to take on risk with their DCPs. There is little evidence that the wife’s characteristics affect the investment decisions of married men.  相似文献

In 2005, the National Science Foundation funded a number of projects to study the impact of Hurricane Katrina. The current article provides an overview of several research approaches used to conduct post-Katrina research. Each method had some advantages and disadvantages. The post-disaster context meant that experience from traditional survey methods often did not apply. Comparisons of advantages and disadvantages associated with each sampling method serve to inform future post-disaster research and illuminate the limits of classical research methods.  相似文献

BackgroundSevere perineal tears sustained during childbirth cause significant distress and morbidity amongst women. The objective of this study was to compare the use of straight scissors for cutting an episiotomy with the use of curved scissors, which are designed to curve away from the anal sphincter.MethodsWe used a single-centre, randomised feasibility trial. The intervention was the use of curved scissors. Women were recruited during a prenatal visit and randomised in the delivery suite, when it became clear that an episiotomy was required. The feasibility outcomes were the proportion of women able to be recruited, randomised and followed up. We also calculated the incidence of obstetric anal sphincter injury when either straight or curved scissors were used to cut an episiotomy. Other outcomes assessed were pain, length of hospital stay, perineal infection and perineal dehiscence.ResultsOf the 155 patients recruited in the prenatal period, only 20 (12.9%) were eventually randomised at birth. The main reasons for the high loss were that women either did not have a vaginal delivery (38, 24.5%), or they did not need an episiotomy (72, 46.5%). Rates of obstetric anal sphincter injury and other outcomes were similar between groups.DiscussionAnal sphincter injury during childbirth remains an important problem. Although the use of curved scissors provides a theoretical solution, we found that the high attrition rate made feasibility of conducting a suitably powered, randomised trial using the current design untenable. Alternative strategies have been suggested to make any future study more viable.  相似文献

Research among adolescent samples has consistently demonstrated that a hopeful mindset is associated with resilience and global well-being. Further, research suggests that hope is influenced from an early age from connections with supportive caregivers. However, because older youth in the child welfare system may lack supportive caregivers, alternative sources of hope may be needed. To test a theory that supportive child welfare caseworkers can serve as external sources of hope, we conducted a cross-sectional study of youth in the child welfare system from a single state (N = 149). Using surveys with established scales to measure the variables of interest, the study tested a structural equation model of (1) youth's external hope in their caseworker as a driver of (2) internal hope in themselves leading to (3) more positive perceptions of academic success. Perceptions of academic success were chosen as the final consequence of the model because academic success has been linked to many other variables of well-being across the lifespan. The results indicate that the proposed structural model fits the data well (χ2 = 327.9, df = 150; P < 0.001; root-mean-square error of approximation [RMSEA] = 0.09 [90% confidence interval – CI: 0.076, 0.103]; comparative fit index [CFI]: 0.920; standardized root-mean-square residual [SRMR]: 0.05). The results indicate that youths' hope in themselves had origins in external hope in the caseworker. Moreover, the final consequence was an increase in perceptions of academic success. Such results have implications by revealing how case management services can positively influence foster youths' hope and thereby influence their academic success.  相似文献

In recent years, scholars have begun to investigate the role of digital technologies, namely the Internet, in facilitating growth in sexual commerce. Recent studies investigate the ways the Internet shapes the experiences of sex workers and how sex workers use the Internet to maximize profits and reduce risk exposure. Overall, scholars strategically frame sex work in a digital era in terms of affordances. In doing so, they can note the positive changes in the work experiences of these workers. However, I argue that this literature is altogether too optimistic, and in focusing primarily on the affordances of Internet‐based sex work, these scholars neglect the new dangers that emerge online. In addition, by focusing only on the online practices of escorts, these scholars paint a homogenized portrait of digital sex work and neglect the diversity of labor performed by sex workers. This literature also neglects the diversity among sex workers themselves (e.g., race, ethnicity, class, gender, age, and ability). In order to address these limitations, I make nine specific suggestions for future lines of inquiry.  相似文献
