Costs and Rewards of Children: The Effects of Becoming a Parent on Adults' Lives

How do new parents differ from their childless counterparts in social and psychological resources, daily strains, and psychological well‐being? Using a nationally representative panel of 1,933 adults who were childless at the first interview, we compare 6 indicators of adults' lives for those who became parents and those remaining childless several years later, controlling for earlier states. Becoming a parent is both detrimental and rewarding. With the exception of social integration, which is greater for all groups of new parents compared with their childless counterparts, the effects of parental status on adults' lives vary markedly by gender and marital status. Unmarried parents report lower self‐efficacy and higher depression than their childless counterparts. Married mothers' lives are marked by more housework and more marital conflict but less depression than their childless counterparts. Parental status has little influence on the lives of married men.     

Dose-Response and Risk Assessment of Airborne Hexavalent Chromium and Lung Cancer Mortality

This study evaluates the dose-response relationship for inhalation exposure to hexavalent chromium [Cr(VI)] and lung cancer mortality for workers of a chromate production facility, and provides estimates of the carcinogenic potency. The data were analyzed using relative risk and additive risk dose-response models implemented with both Poisson and Cox regression. Potential confounding by birth cohort and smoking prevalence were also assessed. Lifetime cumulative exposure and highest monthly exposure were the dose metrics evaluated. The estimated lifetime additional risk of lung cancer mortality associated with 45 years of occupational exposure to 1 microg/m3 Cr(VI) (occupational exposure unit risk) was 0.00205 (90%CI: 0.00134, 0.00291) for the relative risk model and 0.00216 (90%CI: 0.00143, 0.00302) for the additive risk model assuming a linear dose response for cumulative exposure with a five-year lag. Extrapolating these findings to a continuous (e.g., environmental) exposure scenario yielded an environmental unit risk of 0.00978 (90%CI: 0.00640, 0.0138) for the relative risk model [e.g., a cancer slope factor of 34 (mg/kg-day)-1] and 0.0125 (90%CI: 0.00833, 0.0175) for the additive risk model. The relative risk model is preferred because it is more consistent with the expected trend for lung cancer risk with age. Based on statistical tests for exposure-related trend, there was no statistically significant increased lung cancer risk below lifetime cumulative occupational exposures of 1.0 mg-yr/m3, and no excess risk for workers whose highest average monthly exposure did not exceed the current Permissible Exposure Limit (52 microg/m3). It is acknowledged that this study had limited power to detect increases at these low exposure levels. These cancer potency estimates are comparable to those developed by U.S. regulatory agencies and should be useful for assessing the potential cancer hazard associated with inhaled Cr(VI).

福州市社区空巢老年人健康状况调查

目的了解空巢老年人的健康现状及其影响因素,为老龄工作提供科学依据。方法2002年4~5月进行入户调查,采用分层整群抽取福州市鼓楼、台江、仓山三个区60岁及以上的社区老年人,共得到有效样本1767例,其中空巢老人696名。空巢老人躯体健康、生活自理能力(ADL)、经济状况、精神健康、社会健康5个维度的健康状况及其影响因素的调查是本次研究的主要内容。结果福州市社区空巢老年人占老年人总体比例的39%,其中男性多于女性;由logistic检验得出空巢老年人健康状况受年龄、性别、原职业、是否赞成非家庭养老方式、锻炼程度等因素的影响。结论倡导空巢老年人形成良好的生活饮食习惯与自我保健意识,加强对空巢老年人慢性病的防治,丰富老年人的精神生活、社会生活,提高对空巢老年人经济支持,完善社区为老服务,从而改善空巢老年人的健康状况。     

浦东农村青年的新特点与团建工作变数的把握

地处改革前沿的浦东青年农民积极进取、敢于求富,追求知识、渴求文明,易于流动、奔走四方,参与政治、思想开放的新特点,给团建工作带来了新的机遇。目前的关键在于把握好基层团干队伍状态较好、提高自身素质愿望强烈,但基层组织建设尚不适应,团的工作平衡发展不理想,社会化运作机制有待创新的四大变数:明确适应、合理、服务的建团思路,构建社会化服务体系,将基层团建纳入党建总体格局;突出社区团建目标方向,采用组织分构模式。

中医心理学发展的现状及展望

自20世纪80年代起,随着对祖国传统医学中心理学思想的不断挖掘、整理以及临床实践,“中医心理学”逐渐从“中医心理学思想”向一个系统的学科体系过渡,在理论与实践上均取得了一定的成果。中医心理学的进一步发展还需要从突显自身特色、挖掘传统文化的影响、明确学科定位以及培养专业人才等4个方面着手。     

从职业流动看失业阻滞与再就业机制

从职业流动视角来看 ,失业具有无流动性、下向流动性和被迫性 ;失业阻滞在于职业流动的规模不大 ,制度约束性太强和观念滞后 ;再就业具有上向流动性和主动性 ;再就业机制是一个由经济驱动机制、制度改革机制、就业观念转变机制和劳动力自由流动机制构成的综合性、动态性结构体系。     

重塑大学生就业观

随着我国高等教育事业的发展 ,高校的不断扩招 ,就业形势越来越严峻。“先就业 ,后择业 ,再创业”的择业观为各高校所倡行 ,但这种择业观中隐含了不少弊病。从目前我国高校就业形势来看我们认为应当从社会要求、诚信教育、职业理想及规划等方面对学生进行引导和教育 ,在此基础上秉承“先择业 ,后就业 ,再择岗”的择业观 ,才比较符合现实。
