江南"古都"何以成了"古镇"?——关于我国句吴古都的研究

无论是历史记载还是学术界研究的成果都表明:3200多年前,吴泰伯从陕西歧山远奔江南梅里,筑泰伯城、建句吴国、创吴文化,揭开了中国江南文明的序幕。然而,古梅里即今日的梅村却以著名书法家之手,挂出了“江南第一古镇”的匾额。那么梅村究竟是“江南第一古都”还是“江南第一古镇”呢?这是一个原则问题,也是一件很有意义的事情。文章以大量的历史事实及史料深刻地辨析了这个问题,从而进一步论证了无锡梅里是我国吴文化的原生地和核心区,无锡应该打好吴文化这张牌。     

略论统一战线为构建社会主义和谐社会作贡献

本文认为统一战线工作作为不同的矛盾的统一体,体现和追求的也是一种和谐,可以为构建社会主义和谐社会营造良好的政治环境、经济环境和社会环境.而统一战线成员在岗位上作贡献,可以为构建和谐社会营造共同的发展环境.     

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。     

基于Malmquist指数的中国移动动态效率研究

运用DEA-Malmquist指数的方法,分析了2006～2008年中国移动动态效率。研究结果表明,中国移动技术效率明显提升,而技术进步率低,这与中国移动长期依靠高投入换取高增长密切相关。同时对中国移动东、中、西部地区的全要素生产率指数以及构成因素进行对比分析,发现各区域变化率指数逐渐拉开,区域差异将逐渐缩小。     

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。     

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.
