适应性网络空间抽样的设计及估计研究

随着大数据背景下抽样环境复杂化,特别是3S技术（遥感技术、地理信息系统和全球定位系统）日趋成熟,越来越多社会经济问题涉及空间抽样,其样本呈现出规模相对稀少、分布不均匀、局部聚集的特征,使得传统抽样调查面临着严重挑战。本文介绍了适应性抽样技术应用于空间网络环境的基本原理、主要操作步骤和马尔可夫链蒙特卡罗估计推断,并以广州市天河区的商户抽样为例讨论实际操作中应注意的问题,以期为流动人口、环境污染、区域经济研究等方面调查提供理论支撑和实证方法参考。     

高质量发展评价指标体系探讨

党的十九大作出我国经济已由高速增长阶段转向高质量发展阶段的重大判断。测度高质量发展的前提是,在准确理解和把握高质量发展内涵的基础上构建一套科学合理的评价指标体系。通过对高质量发展统计内涵的深入考察,本文在充分梳理、借鉴国内外有关同类评价指标体系的基础上,从“人民美好生活需要”和“不平衡不充分发展”这个社会主要矛盾的两个方面着手,构建了一个由经济活力、创新效率、绿色发展、人民生活、社会和谐5个部分共27个指标构成的高质量发展评价指标体系。该指标体系的特点是：紧扣高质量发展的内涵和新时代社会主要矛盾的变化,指标数量不多但覆盖新发展理念的各个方面,指标不重复,数据易获得。

Policies for Recruiting Talented Professionals from the Diaspora: India and China Compared

Despite the continuous asymmetrical power relations between the Global North and South, the “global race for talent” is no longer a privilege enjoyed only by developed countries. Comparative analysis of policy content and effectiveness has attracted increasing interest. The examination of policy initiatives resulting in return migration of highly‐skilled migrants from the Global North to the Global South, however, remains inadequate. In this article, we provide a comparative analysis of policies targeting high‐level Chinese and Indian professionals including full‐time returnees. Two key differences in policy instruments and outcomes in the two countries are identified and they have implications for migration policies in other countries in the Global South and North.     

Functional and emotional traits of corporate social media message strategies: Behavioral insights from S&P 500 Facebook data

Drawing from literature regarding public engagement, the Elaboration Likelihood Model (ELM), computer-mediated communication research, and emotion psychology, this study examines the effects of companies’ social media communication strategies on public engagement behaviors as indexed by post likes, shares, and comments. Specifically, it investigates how corporate Facebook posts’ functional traits (functional interactivity and vividness) and emotional traits (emotion presence, valence, and strength) impact public engagement online. Through data mining and computer-assisted sentiment analysis of 33,379 posts from 106 Standard & Poor 500 companies’ Facebook accounts, this study finds a negative effect of functional interactivity but a positive effect of vividness on engagement. It also shows that emotional traits overall yield stronger public engagement outcomes. Two-way interactions between emotional and functional features are also detected. Theoretical and practical implications are discussed.

Resolving Rabin’s paradox

We present a theoretical model of Rabin’s famous calibration paradox that resolves confusions in the literature and that makes it possible to identify the causes of the paradox. Using suitable experimental stimuli, we show that the paradox truly violates expected utility and that it is caused by reference dependence. Rabin already showed that utility curvature alone cannot explain his paradox. We, more strongly, do not find any contribution of utility curvature to the explanation of the paradox. We find no contribution of probability weighting either. We conclude that Rabin’s paradox underscores the importance of reference dependence.

     

Experiential Logic in the Transformation of Contemporary China’s Social Governance*

How does Chinese society maintain its orderly operation and show stability and harmony to the utmost while China rapidly transforms its economic system and international circumstances become increasingly complicated? This is an important question that this essay tries to answer, and the analysis mainly involves the exploratory practice of the transformation of Chinese social governance. This exploratory practice is a process through which China constantly breaks through the traditional blockades of vested interests, overcomes newly formed challenges, and forms a new Chinese-style “one axis and multiple components” pattern of social governance during its rapid re-establishment of both social relationship structure and social psychology order on the unbalanced and insufficient conditions of development within its vast territory. During this process, the constant return to the CPC’s mass line, as well as the “mechanism of reversed transmission of pressure,” the “anticipation-led mechanism” and the “mechanism of turning crisis into opportunity” that the CPC has improved during its long-term revolutionary struggles and its deepening of reform and opening-up, has played an important part. The simplistic duplication of Western theoretical analytic paradigms cannot explain the experiential mechanism for the transformation of social governance, which is peculiar to China. The creation of research framework of “system and life” is just an effort for comparison and dialogues with Western classical theories. It is not only helpful for the development of sociology about Chinese transformation, but will provide new knowledge for worldwide social transformation.     

Sex differences in the development of mild cognitive impairment and probable Alzheimer’s disease as predicted by hippocampal volume or white matter hyperintensities

This study examined biological sex differences in the development of mild cognitive impairment (MCI) and probable Alzheimer’s disease (AD) development as predicted by changes in the hippocampus or white matter hyperintensities. A secondary data analysis of the National Alzheimer’s Coordinating Center Uniform Data Set was conducted. We selected samples of participants with normal cognition at baseline who progressed to MCI (n = 483) and those who progressed to probable AD (n = 211) to determine if hippocampal volume or white matter hyperintensities (WMH) at baseline predicted progression to probable AD or MCI and whether the rate of progression differed between men and women. The survival analyses indicated that changes in hippocampal volumes affected the progression to probable AD (HR = 0.535, 95% CI [0.300–0.953]) only among women. White men had an increased rate of progression to AD (HR = 4.396, CI [1.012–19.08]; HR = 4.665, 95% CI [1.072–20.29]) compared to men in other race and ethnic groups. Among women, increases in hippocampal volume ratio led to decreased rates of progressing to MCI (HR = 0.386, 95% CI [0.166–0.901]). Increased WMH among men led to faster progression to MCI (HR = 1.048. 95% CI [1.011–1.086]). Women and men who were older at baseline were more likely to progress to MCI. In addition, results from longitudinal analyses showed that women with a higher CDR global score, older age at baseline, or more disinhibition symptoms experienced higher odds of MCI development. Changes in hippocampal volumes affect the progression to or odds of probable AD (and MCI) more so among women than men, while changes in WMH affected the progression to MCI only among men.
