The influence of acculturation level and family relationships on quality of life among U.S. Chinese older adults

ABSTRACT

The present study examined the influence of acculturation level and family relationships (i.e., positive family support and negative family strain) on quality of life (QOL), using the data from the Population Study of ChINese Elderly (PINE) in Chicago (N = 3159). Controlling for sociodemographic variables and health status, it was found that individuals’ acculturation level and positive family support were positively related to QOL, whereas negative family strain was negatively associated with QOL. More importantly, higher acculturation levels were associated with increased protective effects of positive family support and reduced risk effects of negative family strain on QOL among U.S. Chinese older adults.     

近三十年藏戏研究的发展脉络与趋势——基于计量可视化分析

藏戏被誉为藏文化“活化石”,分别于2006年和2009年被列入国家和世界非物质文化遗产目录。近年来,随着国家大力提倡非物质文化遗产保护和优秀中华文化“走出去”,藏戏研究也日益成为学界关注热点。为了厘清藏戏研究现状,研究热点与趋势,本研究通过CiteSpace与VOSviewer两个主流计量可视化分析软件对国内近三十年藏戏研究成果进行较为详尽的分析,以期为进一步推动藏戏创新研究提供基础数据支撑。直观的可视化分析结果表明：目前藏戏研究处于缓慢发展阶段,但研究内容逐渐向多元化、跨学科方向发展。藏戏研究的核心作者和机构较少,且合作关系不明显。如何服务公共文化体系和非物质文化遗产的传承是目前藏戏研究最新主题。藏戏内涵的丰富性,未来势必会吸引更多学科专家从不同视角对藏戏的传承和保护进行研究。     

鲜卑汉化--论北魏孝文帝改革对民族关系的调整

北魏初年,民族矛盾尖锐,民族关系紧张.北魏孝文帝为缓解民族矛盾,缓和民族关系,巩固北魏统治,对民族关系进行了调整.使鲜卑汉化,是北魏孝文帝改革的重要内容之一.使鲜卑汉化,有利于民族融合和南北的统一,但也导致了北魏的分裂.     

现代化进程中民族文化的嬗变与和谐民族文化的构建

在现代化进程中,民族传统文化遭受到前所未有的巨大冲击,发生了三种类型的嬗变,这是一个动态调整的过程,其结果是使民族文化适应现代化的发展方向,发生嬗变后的民族文化不同于和谐民族文化。现代化进程中民族文化的嬗变,可以说是一个被动的适应过程;构建和谐民族文化,可以说是一个主动的追求过程,它以发生嬗变的民族文化为基础,积极倡导民族和谐的价值取向,为构建和谐民族以及和谐社会提供智力支持。     

基于聚类分析的IPO定价实证研究

股票发行定价作为股市运行极为关键的一环,它的合理与否将直接关系到整个股市运行的效率。选取沪A近4年来发行新股作为研究样本,然后利用多元线性回归方法作分析,可找出影响IPO发行价格的8个主要因素。将定价研究集中到行业中进行,以多元回归得到的主要因素作为聚类指标,选取某一行业(如电力行业)已发行股票为样本,对其进行聚类分析和判别分析,建立该行业新股发行定价的衡量体系,可为拟发行新股的公司提供定价指导。     

全球化进程中的软权力与中国大众文化传播

随着全球化时代的到来,“软权力”日益成为影响国际关系和制约跨文化传播的显要因素之一。以美国为代表的西方“软权力”的扩张对中国大众文化的发展形成了不可忽视的压力和挑战,这昭示着我们在不断增强“硬权力”的同时,务必不能放松对包括大众文化在内的“软权力”的培育和建设。在全球化进程中,我们必须以开放的视野、对话的思维勇敢地去迎接这个挑战,同时在坚持“拿来主义”的前提下,实施“送去主义”的大众文化发展战略。     

印度对中印跨境河流水关系的认知及战略选择

近年来,印度对中印在跨境河流水关系中的不平衡问题非常重视.其中,水文信息不对称以及收益不平衡是印度对水关系不平衡的两个主要认知.基于中印边境的互动历史,印度在对水关系的认知形成中往往会夸大中国的敌意与威胁.据此,印度试图通过建立制度框架、将中印水争议国际化以及竞争性开发跨境河流水资源的战略思维,平衡中国在雅鲁藏布江—布拉马普特拉河水关系中的优势地位.然而受水外交两面性特征和内政的掣肘,印度平衡战略的影响有限,而且更强化了其对雅鲁藏布江—布拉马普特拉河战略安全收益的重视,并使未来中印双方基于水资源共同利益进行合作的难度加大.     

The heterogeneous impact of pension income on elderly living arrangements: evidence from China’s new rural pension scheme

This paper investigates the impact of pension income on living arrangements of the elderly. Taking advantage of a unique opportunity due to the recent establishment and expansion of the New Rural Pension Scheme in China, we explicitly address the endogeneity of pension status and pension income through a fixed-effect model with instrumental variable approach by exploiting exogenous time variation in the program implementation at county level. We find an overall positive effect of pension income on independent living as well as considerable heterogeneity. The positive income effects of the NRPS are concentrated among the elderly with adult children living nearby, of higher socio-economic status, and with better health at baseline; for other groups, the effects are insignificant. We also find that more generous programs exhibit larger effects. Our results highlight that living arrangement is multidimensional in rural China.     

Approximation strategy-proof mechanisms for obnoxious facility location on a line

In the facility location game on a line, there are some agents who have fixed locations on the line where an obnoxious facility will be placed. The objective is to maximize the social welfare, e.g., the sum of distances from the facility to all agents. On collecting location information, agents may misreport the locations so as to stay far away from the obnoxious facility. In this paper, strategy-proof mechanisms are designed and the approximation ratio is used to measure the performances of the strategy-proof mechanisms. Two objective functions, maximizing the sum of squares of distances (maxSOS) and maximizing the sum of distances (maxSum), have been considered. For maxSOS, a randomized 5/3-approximated strategy-proof mechanism is proposed, and the lower bound of the approximation ratio is proved to be at least 1.042. For maxSum, the lower bound of the approximation ratio of the randomized strategy-proof mechanism is proved to be 1.077. Moreover, a general model is considered that each agent may have multiple locations on the line. For the objective functions maxSum and maxSOS, both deterministic and randomized strategy-proof mechanisms are investigated, and the deterministic mechanisms are shown to be best possible.     

劳动参与率与劳动力增长:1982～2050年

劳动参与率是影响劳动力变化的三要素之一。它一方面具备相对稳定的模式,另一方面又受到一系列个人和外部因素的影响。文章基于普查数据,着重分析了劳动参与的年龄模式和主要影响因素,并预测了未来劳动力的发展趋势。结果发现,中国劳动参与年龄模式正趋向于稳定的倒U形,存在着明显的性别、城乡差异。回归结果表明,高中以上受教育程度可大大提高劳动参与,特别是女性的劳动参与,表明人力资本是未来劳动力发展的一个根本因素。预测结果显示,劳动力规模10年后将不可避免地出现负增长,同时中老年劳动力的比重也会大幅上升。对此,应采取相应措施以减轻劳动力变化所带来的震荡。
