西夏开国人口考论

本文在认真研读相关文献的基础上 ,对西夏开国人口作了较为深入细致的考察和论述 ,认为由于史料采信等原因 ,以往研究与历史事实多有出入 ,存在不少问题。文章进而指出 ,特定的历史与地理条件决定了西夏自建国伊始即是一个“土地有限 ,人民有数”的地方性民族割据政权 ,其开国兵力不过 30余万 ,人口总数则仅及百万     

人口较少民族文化艺术遗产的新开发现象

我国 2 2个人口在 10万以下的少数民族主要生活在西部地区。近年来 ,他们在对待文化艺术遗产方面出现了一些新的特征 :歌手们更加关注自己民族的歌曲 ;地方政府在城镇和旅游建设中强调突出民族特色 ;农牧民组织民族服装模特队等。在此把这种发展变化称为“新开发”现象。     

百越民族的水稻、浮稻与“鸟田”传说新解

《越绝书》、《吴越春秋》等古籍中记载的“鸟田” ,有的学者诠释为“以鸟助耕” ,这纯属误解。本文通过对百越民族谷物起源神话的分析 ,得出”鸟田”、“雒田”研究的新结论 :它们来源于古代百越民族的鸟、狗取稻种神话 ,原意是指水稻、浮稻和水田。     

Black men teaching: toward a theory of social isolation in organizations

ABSTRACT

While there continues to be increasing research about Black male teachers’ school-based experiences, there is less empirical evidence on the variation in these experiences for this subgroup. Drawing on Kanter’s Theory of Numbers and Group Composition, the researcher used the qualitative method to compare the perceptions of Black male teachers in schools that employ just one Black male teacher versus schools with larger numbers of Black male teachers. A theory of social isolation in organizations is proposed to explain differences in the variation of school-based experiences for Black male teachers. When compared to Black men in schools with larger percentages of Black male teachers on the faculty, those Black men who were the only Black male teachers on their faculty were more likely to describe feeling socially isolated and disconnected from their colleagues.     

漂泊的洞察——我的学术研究之路

本文作者作为中国恢复高考制度后的第一届大学生,以亲身经历讲述了其学术成长之路。其学术研究从五个方面概括:一是都市人类学,包括乡村都市化、城市少数民族以及传统乡村研究主题在城市的延续;二是农民工研究,从发起农民工研究,到散工研究,从"二元社区"研究到"打工经济"研究等;三是乡村研究,以凤凰村为起点,研究了岭南、中部以及西部的乡村社会;四是族群研究,以澳门族群研究为起点,对中国族群认同与关系作研究;五是应用研究。     

社会工作视野下的城市少数民族流动人口问题

城市少数民族流动人口问题正逐渐成为社会关注的一大热点,文章主要对城市少数民族流动人口的现状、特点,对城市发挥的积极功能和城市少数民族流动人口问题的具体表现作一概述,并从社会工作这一新的视角分析了城市少数民族流动人口问题的成因,在此基础上就社会工作如何介入此问题提出一些建议.     

浅析中国土族人口分布格局及其社会发展

人口分布格局,既是人在空间分布上呈现出来的地理状态,又是许多附着于分布环境上的社会人文变量的外在表现,因此对其进行研究具有探索自然和认识社会的双重意义。本文就中国土族人口的分布格局进行探讨,从历史和现实两方面分析了形成这种分布的原因,并在此基础上探讨了与人口分布格局密切相关的人口城市化、人口流动、人口素质提高、区域经济发展等社会热点问题,以期为政府政策的制定提供可靠的依据。     

Consistent Probabilistic Social Choice

Two fundamental axioms in social choice theory are consistency with respect to a variable electorate and consistency with respect to components of similar alternatives. In the context of traditional non‐probabilistic social choice, these axioms are incompatible with each other. We show that in the context of probabilistic social choice, these axioms uniquely characterize a function proposed by Fishburn (1984). Fishburn's function returns so‐called maximal lotteries, that is, lotteries that correspond to optimal mixed strategies in the symmetric zero‐sum game induced by the pairwise majority margins. Maximal lotteries are guaranteed to exist due to von Neumann's Minimax Theorem, are almost always unique, and can be efficiently computed using linear programming.     

Nonparametric Estimation of the Number of Drug Users in Hong Kong Using Repeated Multiple Lists

We update a previous approach to the estimation of the size of an open population when there are multiple lists at each time point. Our motivation is 35 years of longitudinal data on the detection of drug users by the Central Registry of Drug Abuse in Hong Kong. We develop a two‐stage smoothing spline approach. This gives a flexible and easily implemented alternative to the previous method which was based on kernel smoothing. The new method retains the property of reducing the variability of the individual estimates at each time point. We evaluate the new method by means of a simulation study that includes an examination of the effects of variable selection. The new method is then applied to data collected by the Central Registry of Drug Abuse. The parameter estimates obtained are compared with the well known Jolly–Seber estimates based on single capture methods.
