Little is known about the differences in mortality among non-institutionalized geriatric and younger patients with schizophrenia. In this study long-term mortality and suicidal behavior of all the geriatric (age > or = 65 years), middle-age (age 41-64 years), and young (age 15-40 years) subjects with schizophrenia living in a Chinese rural community were compared. A 10 year follow-up investigation among a 1994 cohort (n = 510) of patients with schizophrenia was conducted in Xinjin County, Chengdu, China. Compared with young subjects, geriatric subjects with schizophrenia were more likely to be female, have more previous physical illness, never accepted treatment, and practice religious (p < or = 0.01). There were no significant differences of suicide attempts among the three groups. Young subjects had a higher rate of suicide (1,033.8 per 100,000 person-years), and geriatric subjects had a higher rate of deaths due to other causes (accident and natural causes) (4,314.2 per 100,000 person-years). Standardized mortality ratios for both suicide and deaths due to other causes were highest in young subjects and the lowest in geriatric subjects. Patients with schizophrenia in all age groups had a marked increase in mortality and suicide. Specific intervention strategies for decreasing mortality and suicide should be developed for patients with schizophrenia in different age groups. 相似文献

The focus of this study was the relation between both gender role self-concept and gender role attitudes with gender-related behavior of interacting partners. We observed gender-typed communication behaviors of mixed-sex and same-sex dyads and measured gender role self-concept and gender role attitudes. Thirty mixed-sex dyads, 19 women dyads, and 15 men dyads participated in a behavior observation study. The results revealed that the activation of gender role self-concept varies depending on the gender of the interacting people. Furthermore, we found that context and gender of the interacting persons moderated the relation between self-concept and behavior. Participants' gender role attitudes did not correlate with their own behaviors but did with their partners' behaviors. 相似文献

Urban animals and birds in particular are able to cope with diverse novel threats in a city environment such as avoiding novel, unfamiliar predators. Predator avoidance often includes alarm signals that can be used also by hetero-specifics, which is mainly the case in mixed-species flocks. It can also occur when species do not form flocks but co-occur together. In this study we tested whether urban crows use alarm calls of conspecifics and hetero-specifics (jackdaws, Corvus monedula) differently in a predator and a non-predator context with partly novel and unfamiliar zoo animal species. Birds were tested at the Tiergarten Schönbrunn in the city of Vienna by playing back con- and hetero-specific alarm calls and control stimuli (great tit song and no stimuli) at predator (wolf, polar bear) and non-predator (eland antelope and cranes, peccaries) enclosures. We recorded responses of crows as the percentage of birds flying away after hearing the playback (out of those present before the playback) and as the number of vocalizations given by the present birds. A significantly higher percentage of crows flew away after hearing either con- or hetero-specific alarm calls, but it did not significantly differ between the predator and the non-predator context. Crows treated jackdaw calls just as crow calls, indicating that they make proper use of hetero-specific alarm calls. Responding similarly in both contexts may suggest that the crows were uncertain about the threat a particular zoo animal represents and were generally cautious. In the predator context, however, a high percentage of crows also flew away upon hearing the great tit control song which suggests that they may still evaluate those species which occasionally killed crows as more dangerous and respond to any conspicuous sound. 相似文献

One correlational study examined whether virtual contact via Facebook is positively related to intergroup relations. The followers of two online campaigns from Iran and Israel—whose countries have been in a politically hostile relationship since the 1980s—indicated the amount of direct and indirect virtual (Facebook) and real-life outgroup contact they have had, a number of quality and affective judgments about that contact, and completed an affective prejudice measure about the respective outgroup. Overall, contact was negatively associated with affective prejudice, providing support for the contact hypothesis in a specific and exclusively virtual setting with citizens of hostile nations. Previously experienced real-life contact did not moderate the results, suggesting that virtual contact has an independent link to positive outgroup attitudes. 相似文献

Males typically surpass females in spatial performance, an outcome that may be linked to testosterone and estrogen. The authors (a) review physiological mechanisms, developmental periods, and past empirical work relevant to sex steroids' effects on human spatial performance and (b) report an experimental study of the role of actively circulating sex steroids in adolescents being treated for delayed puberty (N = 55; mean age = 13.70 years). Sex steroids (simulating early, middle, and late puberty) and placebos were given alternately over 21 months and spatial tests were given every 3 months. Spatial performance showed traditional sex differences but did not vary with levels of actively circulating sex steroids. 相似文献

A correlational study on Facebook investigated the relationship between virtual intergroup contact and general attitudes toward diverse out‐groups. A so‐called Facebook application retrieved objective data about the intercultural composition of participants' Facebook networks. The exact percentage of out‐group friends correlated significantly with more favorable out‐group attitudes. This relationship was mediated by humanitarian‐egalitarian values, suggesting that having intercultural friends on Facebook is positively linked to value orientations, which in turn are associated with more favorable intergroup attitudes. In addition, identification with one's own national group and real‐life experience abroad did not moderate the results. Overall, although causation cannot be inferred because of the correlational design of our study, results suggest that virtual intergroup contact may positively affect attitudes. 相似文献
