西部民族地区公共卫生服务项目绩效结构模型构建与实证分析——基于N省的数据调查

构建绩效指标是整个绩效评价进程中最重要的内容和核心点.本文从西部民族地区实际出发,在文献梳理的基础上,从理论视角构建了公共卫生服务项目绩效结构模型,假设西部民族地区公共卫生服务项目绩效可由投入、运行和效果三个要素构成;然后运用结构方程及AMOS20.0数据分析工具,基于N省的数据调查,验证本文提出的结构模型,并首次测算出绩效各构成要素对绩效的贡献程度.实证表明,运行要素是其绩效中最为重要的,而投入对其绩效的影响程度最小,并据此提出对策建议,从而为西部民族地区有针对性的提高公共卫生服务项目绩效提供实证检验的数据证据.

Racial and Ethnic Differences in the Prevalence of Depressive Symptoms Among U.S. Nursing Home Residents

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.

How Effective are Helpers to Older Adults’ Life Satisfaction?

The effectiveness of help received from home care workers and volunteers to the life satisfaction of community-dwelling older adults is vital but uncharted. To address the effectiveness, this study aims to optimize the use of social resources for the older adults’ life quality. The study thus surveyed 398 community-dwelling older adults in a city of China about the help and life satisfaction. Results showed a significant positive effect of help from home care workers, but not that from volunteers, on the older adult’s life satisfaction. Moreover, the effect of help from volunteers was significantly greater when the older adult had higher education or lower family income. These effects are explicable with resource theory and need fulfillment theory. They imply the worth of promoting help from home care workers generally and volunteers conditionally to champion older adults’ life satisfaction.     

人的抽象存在与虚无--20世纪80年代中国先锋小说的人性观

本文认为,学界对于20世纪80年代中国先锋小说的现有研究只注重叙事形式的探讨是其不足。如果研究要更进一步,就不能忽略先锋小说人性观中所包含的意识形态方面的蕴含。先锋小说撇开社会文化因素写人的抽象存在,在哲学的意义上赋予人与人之间平等的地位,超越了庸俗社会学的机械决定论,为人的解放做出了一定的贡献。但先锋小说人性虚无主义的悲观态度,也导致了它艺术上的不足,使得这种创作无法继续而最终转向了新的写作方式。     

不确定需求下考虑大数据投资决策的供应链鲁棒优化及协调模型

针对由数据公司、制造商和零售商组成的三级供应链系统,在仅知需求均值和方差信息下,建立了集中和分散两种决策情况下的供应链鲁棒优化模型。集中决策下,全体供应链成员共同决定产品零售价和产品生产数量;分散决策下,数据公司作为主方,决定需求信息零售价,制造商和零售商作为从方,分别决定产品批发价和产品订货数量。针对两种决策下的供应链鲁棒优化模型,给出了相应的最优决策,分析了大数据投资成本、消费者异质性需求满足程度等系统参数对供应链决策的影响。进一步,设计了能实现三级供应链完美协调的利润共享契约。最后,通过数值算例验证了所建模型和契约协调的有效性。研究表明,在集中和分散决策下,大数据投资成本只有在满足一定条件下,投资大数据才有利于供应链成员及系统利润的改善。特别地,与无协调时的情况相比,虽然协调机制下相关系统参数对供应链成员决策及利润绩效的作用机制存在差异,但文中提出的利润共享契约在一定条件下能够显著改进供应链成员利润且实现供应链完美协调。

诗意地栖居--贾宝玉的死亡遐想与诗性生存追求

宝玉的死亡遐想和他诗性生存追求息息相关,这主要体现在三个层面:背离儒家主流文化的死亡模式,维护自己本真的生存状态;呼唤充满灵性的心灵,感受存在的深度;迷恋女儿世界,寻找灵魂的居所。这三个层面相互依存转化,共同建构了一个不同于世俗理性的真、善、美的自由和谐的生存境界,这种生存追求有相对积极的价值和意义。     

秦末浙地"换了人间"说献疑

<越绝书>文本所言,至多为今浙江境内一次扩散型移民,并非对今浙江全境人口结构的改变;司马迁胪陈秦始皇君临天下后行踪,含其移民举措和封禅会稽之一举一动,只字未及越地移民,说明此事并不存在,即使存在亦规模小至可以忽略不计;所谓"因徙天下有罪谪吏民"实乃与民政无关的边防部署之一,秦末"中原人民首次大规模地徙居越地"当为后人想象;浙地历代都有移民的迁入和迁出,但没有一次属于对人口结构的全局性改变.
