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

Modern times:
an ethnographic study on the quality of life of people with a high support need in a Flemish residential facility 总被引:1,自引:1,他引:0
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

Few articles have addressed the relation between the ownership structure and the composition of the boards. The results of the analysis performed on a sample of Spanish listed companies for the period 2004–2011, show that in markets where corporate ownership is highly concentrated, it is necessary to devote special attention to blockholders and to differentiate the figure of the independent directors from the group of outsiders. The results confirm a negative and decreasing relation between blockholders and the percentage of independents while insiders’ ownership is only significant if one looks at the percentage of outsiders as a whole, in which case it shows a U-shaped quadratic relation. 相似文献

Anurans and birds rely on sound for a number of social behaviors. Species that use roadside habitats are exposed to traffic
noise that can mask important social signals and directly affect the community diversity and composition. We evaluate the
impact of traffic noise on anuran and bird species richness, species occurrence, and composition in Puerto Rico, where there
is a high density of highways and cars that generate high levels of noise pollution. We compared paired forest sites near
(100 m, n = 20, dB > 60) and far (>300 m, n = 20, dB < 60) from highways, with similar vegetation structure, but different levels of noise. We found that the anuran
community was not affected by traffic noise. In contrast, bird species richness and occurrence were significantly lower in
sites near the highway, and bird species composition also varied significantly. Bird species with low-frequency songs were
only detected in sites far from highways. The differences in the ecology and communication behavior between anurans and birds
could explain these results. Anurans mainly call at night, when traffic activity was low. In contrast, bird singing activity
occurs during the day and overlaps with the high levels of traffic noise. In addition, in natural habitats, Puerto Rican anurans
occur at high densities and form noisy choruses (>80 dB), which may allow them to tolerate high levels of anthropogenic noise. 相似文献

The study of children' and adolescents' perceptions of bullying has become a topic of particular interest in the scientific community as it enables one to better understand the processes of aggression and victimization, and consequently the emergence of new perspectives that will allow anti-bullying programs to be better matched to their targets. This paper analyzes adolescents' perceptions of bullying and the forms in which it is manifest, finding a difference between the perceptions held by aggressors and victims. It also examines the influence of the factor 'frequency of aggression' on those perceptions. The data acquisition instrument was a questionnaire applied to a sample of 2295 teenagers (M = 13.8, SD = 1.4). The results show that the victims' sole criterion for their conceptualization and identification of bullying is the 'intent to cause harm'. The aggressors, however, stress the criterion of 'power imbalance' rather than 'intent to harm'. The results also show that, as the aggression committed or suffered decreases in frequency, both aggressors and victims tend to legitimize various modes of bullying as a form of peer interaction. 相似文献

Monitoring Urban Quality of Life: The Porto Experience 总被引:2,自引:0,他引:2
This paper describes the monitorin g system of the urban quality of life developed by the Porto City Council, a new tool being
used to support urban planning and management. The two components of this system – a quantitative approach based on statistical
indicators and a qualitative analysis based on the citizens’ perceptions of the conditions of life – are presented. The strengths
and weaknesses of these two approaches adopted in the project are reviewed. It is argued that, in order to achieve a deeper
understanding and more effective measurement of urban quality of life, both kinds of measurements are useful and complement
each other. 相似文献
