夏尔巴人的历史与现状调查

夏尔巴人,中尼边境地区的一个民族。北宋末年,蒙古铁骑驰骋在茫茫草原。金戈铁马荡平了大宋王朝,北方的西夏王朝也消失在历史的云烟深处,空渺无迹,不知去向,给后人留下了一个个悬念。然而尼泊尔的素伦昆布和我国西藏樟木小镇及其下属的立新和雪布岗村落,可能就是神秘的党项人后裔的归宿。从夏尔巴人的族源、风俗习惯、语言艺术、宗教信仰等方面来看,与我国的藏族极为相似,渊源于藏文化或喜马拉雅文化带民族。研究夏尔巴人不仅是对我国民族学研究的补充,更重要的是对于西部边陲的巩固稳定和中尼政治、经济、文化的交流有积极的意义。     

The binary search decomposition in a decentralized organization

An analytic model of the resource allocation decision process in a decentralized organization is presented. The model follows the philosophy of Kornai and Liptak in its decomposition procedure but employs the binary search technique in its resource allocation process. Briefly, the model provides two important concepts relevant to the decision making process of a decentralized organization: (1) satisficing technique of coordination and (2) simulation of a resource allocation decision process.

Order test for high-dimensional two-sample means

We propose a new method to test the order between two high-dimensional mean curves. The new statistic extends the approach of Follmann (1996) to high-dimensional data by adapting the strategy of Bai and Saranadasa (1996). The proposed procedure is an alternative to the non-negative basis matrix factorization (NBMF) based test of Lee et al. (2008) for the same hypothesis, but it is much easier to implement. We derive the asymptotic mean and variance of the proposed test statistic under the null hypothesis of equal mean curves. Based on theoretical results, we put forward a permutation procedure to approximate the null distribution of the new test statistic. We compare the power of the proposed test with that of the NBMF-based test via simulations. We illustrate the approach by an application to tidal volume traces.     

中西部地区新型城镇化及其推进:湖南个案

中西部地区新型城镇化是我国推进新型城镇化战略的重点和难点。浏阳经济技术开发区在推进新型工业化过程中,实施了低成本战略,以"绝对成本优势"确定产业定位,以"比较成本优势"招商引资,以"低风险成本"助推产业扩张。在推进城镇化时,浏阳经济技术开发区从降低交易成本切入,亦实施了低成本战略。浏阳经济技术开发区的城镇化路径,为中西部地区城镇化提供了如下启示:城镇化发展要以工业化为依托、不可盲目造城;工业化发展必须因地制宜、立足本地优势;推动城镇化政府要有所作为,更要发挥市场决定性作用。

基于数学建模的人口结构与经济发展研究

文章通过梳理我国第六次人口普查的相关数据,建立了人口总量增长、未来老龄人口和劳动人口三个预测模型,通过SPSS软件拟合人口出生率和死亡率的发展曲线,及劳动和老龄人口历年增长率的曲线方程,得到预测未来人口总量、老龄人口和劳动人口所占比例发展趋势。预计在2026年我国人口总量达到峰值(142010万人),这与国家人口战略研究报告中预测的数据接近。根据计算的结果,结合修正的道格拉斯模型,讨论了人口结构的变化对经济发展的影响。     

The Impact of Accident Attention,Ideology, and Environmentalism on American Attitudes Toward Nuclear Energy

This study involves the analysis of three waves of survey data about nuclear energy using a probability‐based online panel of respondents in the United States. Survey waves included an initial baseline survey conducted in early 2010, a follow‐up survey conducted in 2010 following the Deepwater Horizon oil spill in the Gulf of Mexico, and an additional follow‐up conducted just after the 2011 Fukushima, Japan, nuclear accident. The central goal is to assess the degree to which changes in public views following an accident are contingent on individual attention and respondent predispositions. Such results would provide real‐world evidence of motivated reasoning. The primary analysis focuses on the impact of Fukushima and how the impact of individual attention to energy issues is moderated by both environmental views and political ideology over time. The analysis uses both mean comparisons and multivariate statistics to test key relationships. Additional variables common in the study of emerging technologies are included in the analysis, including demographics, risk and benefit perceptions, and views about the fairness of decisionmakers in both government and the private sector.     

Disinformation,performed: self-presentation of a Russian IRA account on Twitter

ABSTRACT

How disinformation campaigns operate and how they fit into the broader social communication environment – which has been described as a ‘disinformation order’ [Bennett & Livingston, (2018). The disinformation order: Disruptive communication and the decline of democratic institutions. European Journal of Communication, 33(2), 122–139] – represent critical, ongoing questions for political communication. We offer a thorough analysis of a highly successful disinformation account run by Russia’s Internet Research Agency: the so-called ‘Jenna Abrams’ account. We analyze Abrams’ tweets and other content such as blogposts with qualitative discourse analysis, assisted by quantitative content analysis and metadata analysis. This yields an in-depth understanding of how the IRA team behind the Abrams account presented this persona across multiple platforms and over time. Especially, we describe the techniques used to perform personal authenticity and cultural competence. The performance of personal authenticity was central to her persona building as a likeable American woman, whereas the performance of cultural competence enabled her to infiltrate American conservative communities with resonant messages. Implications for understanding disinformation processes, and how some aspects of the hybrid media system are especially vulnerable to hijacking by bad actors are discussed.
