ABSTRACT

This study examined the effects of the village communal living model on depressive symptoms, focusing on mediating roles of perceived environment among rural older women in South Korea. Data came from the sample of residents in 18 housings and their peers in the conventional housing (n = 168). Propensity score analysis and structural equation modeling were used. The results showed the effect of living in VCH on depressive symptoms was mediated distinct aspect of socio-physical environment.  相似文献

This study aimed to examine racial and ethnic differences in significant depressive symptoms among long-term nursing home residents. We analyzed the 2014 national Minimum Data Set linked to a nursing home file and estimated multivariable logistic regressions to determine the associations of race and ethnicities with significant depressive symptoms (score ≥ 10 on the 9-item Patient Health Questionnaire [PHQ-9] scale) and whether associations were explained by resident and nursing home covariates. Stratified analyses further determined independent associations in subgroups of residents. We found that the prevalence rate of PHQ-9 scores ≥ 10 was 8.8% among non-Hispanic White residents (n = 653,031) and 7.4%, 6.9%, and 6.6% among Black (n = 97,629), Hispanic (n = 39,752), and Asian (n = 16,636) residents, respectively. The reduced likelihoods of significant depressive symptoms for minority residents compared to non-Hispanic Whites persisted after sequential adjustments for resident and nursing home covariates, as well as in stratified analyses. The persistently lower rate of significant depressive symptoms among racial and ethnic minority residents suggests that training of nursing home caregivers for culturally sensitive depression screening is needed for improved symptom recognition among minority residents.  相似文献

The study investigates depressive symptoms among 3,431 adolescents aged 13–15 years. The sample comprises both native Norwegian and immigrant adolescents living in Norway. The main finding of the study is that the level of depressive symptoms is significantly higher among the immigrant adolescents than their Norwegian counterparts. When analysed separately for boys and girls, the difference is still significant for boys. Generally depressive symptoms are significantly higher among girls than among boys. Depressive symptoms, especially in boys, may also be related to the degree of urbanization of the area they live in. In cities, there is a significant difference between native Norwegian and immigrant boys, with immigrant boys having a higher level of depressive symptoms than native Norwegians. The implications for future research about immigrant adolescents and their psychosocial adjustment are discussed.

论德国公司法中禁止隐性实物出资问题   总被引:2,自引:0,他引:2  
隐性实物出资是指股东在公司设立或增资时 ,先将股金交给公司 ,然后向公司出售货物 ,并以收回货款的方式收回其缴纳的股金。隐性实物出资的目的是逃避注册法院对实物出资的法定审查 ,其结果是资本真实原则不能切实实施 ,公司本身的利益、小股东的利益尤其是公司债权人的利益可能会受到损害。因此这种出资安排为德国的司法实践所禁止。类似的问题在我国公司的出资实践中也同样存在 ,德国禁止隐性实物出资的做法可供我们借鉴  相似文献

Lack of time is the most frequently reported reason for lack of exercise. This study examines how restriction on the number of working hours affects individuals’ exercise decision. A structural model is constructed to describe the simultaneous decisions of employment and physical activity in the presence of working hour restriction. Using data from the 1992 Health and Retirement Study, this study finds that the working hour restriction is partly responsible for the physical inactivity among older American workers. When the working hour restriction is binding from below, an increase in the number of hours required on the job considerably reduces the probability of engaging in frequent exercise. The results imply that partial relaxation of working hour restrictions may be considered to promote frequent exercise.

IntroductionThe Vietnam Physical Activity and Nutrition (VPAN) program aimed to improve physical activity and nutrition for adults aged 50–65 years with Metabolic Syndrome in Vietnam. The VPAN program consisted of a range of resources and strategies, including an information booklet, resistance band, face-to-face education sessions, and walking groups. This process evaluation assessed the participation, fidelity, satisfaction, and reasons for completing and not-completing the VPAN.MethodsData were collected by mixed-methods from a sample of 214 intervention participants. Quantitative data were collected via surveys (n = 163); qualitative data via face-to-face exit interviews with intervention program completers (n = 10) and non-completers (n = 10), and brief post education session discussions.ResultsMost participants (87%–96%) reported the program resources and strategies useful, assisting them to increase their physical activity level and improving their diet. The education sessions were the most preferred strategy (97%) with high attendance (>78% of participants). The main reasons for withdrawal were work commitments and being too busy.ConclusionThe evaluation indicated that the program reached and engaged the majority of participants throughout the six-month intervention. The combination of printed resources and face-to-face intervention components was a suitable approach to support lifestyle behavioural change in the Vietnamese population.  相似文献

分析了辽河油田新开地区沙一段和沙三段不同相带、不同地区、不同埋藏深度的储层物性参数特征;研究了这些参数与岩石组分和结构、沉积相带以及埋藏深度之间的关系;对不同物性条件、不同相带、不同地区、不同埋深的储层铸体薄片进行了选择性观察。研究认为:影响该地区储层物性的因素有溶蚀作用、充填胶结作用、压实作用和沉积条件。在这几个因素中,溶蚀与胶结作用是最主要的,对该地区储层物性起了决定性控制作用;压实作用次之;沉积条件只在一定程度上对储层物性有影响。  相似文献
