ABSTRACT

Empowerment is a concept widely used in several policy documents and is presented, in social work and social care professional universes, as an operative process to reduce vulnerability and to increase the power, or capabilities, of individuals and groups to make choices and to transform these into actions and results. However, to move beyond rhetoric and paternalistic practices, we need to understand what empowerment really means and implies in different contexts, and especially, how to evaluate what has changed (outcomes) or is changing (processes), both on an individual and a collective level.  相似文献

Abstract

“Blood Glucose Control and the Evolution of Diabetic Retinopathy and Albuminuria: A Preliminary Multicenter Trial,” The Kroc Collaborative Study Group. We conducted a prospective multicenter randomized trial to determine both the feasibility of maintaining blood glucose control at differing levels and the effect of improved control on diabetic microangiopathy and albuminuria. Seventy patients with diabetes (low C-peptide level) with nonproliferative retinopathy were randomly assigned to continuous subcutaneous insulin infusion or unchanged conventional injection treatment. At entry, both groups had similar demographic, clinical, and glycemic characteristics. Over the succeeding eight months, mean 24-hour glucose concentrations (175 ± 9 mg per deciliter) and glycosylated hemoglobin levels (10.0 ± 0.3%) remained elevated during conventional treatment but fell to nearly normal levels (117 ± 6 mg per deciliter and 8.1 ± 0.2%, respectively) with continuous insulin infusion. The frequency of biochemical hypoglycemia (< 40 mg of blood glucose per deciliter) was similar in both groups, but ketoacidosis occurred only during continuous infusion. The level of retinopathy, assessed from photographs, progressed in both groups. Continuous infusion was associated with slightly more deterioration, mainly because of the appearance of soft exudates and intraretinal microvascular abnormalities. In contrast, elevated albumin-excretion rates fell during continuous infusion but not during conventional treatment. We conclude that maintenance of differing levels of blood glucose is feasible in a multicenter trial and that a nearly normal blood glucose level for eight months does not retard progression of, and may initially worsen, established retinopathy. These preliminary observations indicate the need for longer trials (particularly of primary prevention). (New England Journal of Medicine 1984;311:365-72.)  相似文献

The authors propose to estimate nonlinear small area population parameters by using the empirical Bayes (best) method, based on a nested error model. They focus on poverty indicators as particular nonlinear parameters of interest, but the proposed methodology is applicable to general nonlinear parameters. They use a parametric bootstrap method to estimate the mean squared error of the empirical best estimators. They also study small sample properties of these estimators by model‐based and design‐based simulation studies. Results show large reductions in mean squared error relative to direct area‐specific estimators and other estimators obtained by “simulated” censuses. The authors also apply the proposed method to estimate poverty incidences and poverty gaps in Spanish provinces by gender with mean squared errors estimated by the mentioned parametric bootstrap method. For the Spanish data, results show a significant reduction in coefficient of variation of the proposed empirical best estimators over direct estimators for practically all domains.

Little attention has focused on generational or age-related differences in human immunodeficiency virus/sexually transmitted infection (HIV/STI) risk behaviors among Black men who have sex with men and women (BMSMW). We examined sexual risk behaviors between BMSMW ages 40 and under compared to over age 40. Analysis was conducted using Centers for Disease Control and Prevention (CDC)–sponsored intervention data among BMSMW in Los Angeles, Chicago, and Philadelphia (n = 546). Pearson’s chi-square tests were conducted to evaluate associations between age groups and behavioral outcomes. Logistic regression was used to evaluate the odds of behavioral outcomes by age group, adjusting for sexual orientation and study location, within strata of HIV status. HIV-positive BMSMW over age 40 had 62% reduced odds of having a nonmain female partner of HIV-negative or unknown status compared to those ages 40 and under (adjusted odds ratio [AOR] 0.38, 95% confidence interval [CI] = 0.15, 0.95). Among HIV-negative BMSMW, the older cohort was associated with greater odds of having condomless insertive anal intercourse (IAI) with most recent main male partner (AOR 2.44, 95% CI = 1.12, 5.32) and having a concurrent partnership while with their recent main female partner (AOR = 2.6, 95% CI = 1.10, 4.67). For both groups, odds of engaging in certain risk behaviors increased with increasing age. Prevention efforts should consider generational differences and age in HIV risks among BMSMW.  相似文献

Turkish migrants differ in their fertility and marriage behavior from native Germans. These differences, especially those concerning the link between the two events birth of the first child and first marriage, will be examined in this article by using event history analysis with data of the Generations and Gender Survey from 2005 (main survey) and 2006 (additional survey of Turkish nationals). We address the question to what extent the link between first marriage and starting a family differs between these two groups and if the differences are accounted for by religious or educational differences. The key findings are: Germans often marry between getting pregnant and getting their first child. Turks, however, predominantly get pregnant within marriage. Turkish women who get pregnant before marriage have subsequently worse prospects on the marriage market. These differences are not accounted for by religious and educational differences. It can be assumed, however, that differences between Islam and Christianity are relevant.  相似文献

This research explores a causal model of menopausal symptoms in peri- and postmenopausal women. A community sample of 710 women was assessed regarding menopausal symptoms, and sociodemographic, health- and menopause-related, and lifestyle characteristics. Structural equation modelling was used. Menopausal status predicted skin/facial hair changes (β = .156; p <.001), vasomotor (β = .122; p <.001) and sexual symptoms (β = .158; p <.001). Age was significantly associated with cognitive impairment (β = .087; p = .003), aches/pain (β = .072; p = .006), urinary (β = .115; p = .004) and also sexual symptoms (β = .107; p = .021). Several menopausal symptoms are predicted, not only by menopausal status, but also by age progression, among other variables; this should be considered in the context of a well-adapted menopausal transition.  相似文献

This contribution deals with the relevance of the employee??s personality for brand relationship quality in the service sector. The necessity for employees of being conform to a brand to strengthen its image makes the fit between the employee and the brand personality of special interest regarding this study. The so developed causal model is evaluated by conducting an empirical study whereby one of the leading financial institutes in Germany serves as study object. Results show a high relevance of Love/Passion, Intimacy and Partner Quality for brand loyalty. Further, these dimensions of the relationship quality are determined by the fit between brand personality and employee personality with regard to the aspect competence and sincerity. The relations between the personality fit constructs and the influenced dimensions of brand relationship quality are intensified by a positive consumer evaluation of the employees with regard to the relevant personality traits.  相似文献

This ethnographic study shows the impact of the care system on clients' and staff's life experiences, with the clear distance between these two groups as one of the core issues. Together with a dominant care approach and a well established but subtile system of control, it makes them function in systems that are characterized by an oppressing care culture. Learned helplessness prevents both groups of acting upon quality of life outcomes. The idea of supporting a life of good quality through merely improving these traditional care systems should therefore be considered with caution, and real alternatives should be considered to open this barrier of the oppressing care culture.  相似文献
