族群互动中的文化自觉——以广西客家族群关系为例

本文以广西客家族群关系为例,探讨族群关系在文化自觉的指令下,族群互动的方式、特征、规律及其作用.认为以文化自觉为指导的族群互动体现了国内族群关系的一般规律与特征;造就了和谐的族群关系,使客家文化成功转型不断创新,并使客家族群和汉民族不断发展壮大;文化自觉是构建和谐社会的根本途径;对构建现代和谐的国内国际族群关系具有显著意义与作用.     

民族地区发展可再生能源的现实分析及政策选择

可再生能源分布与民族地区存在高度一致性,民族地区发展可再生能源,具有重大的现实意义和战略意义.与传统化石能源开发利用对生态环境造成的破坏和压力相比,民族地区利用资源优势和政策机制发展可再生能源,不仅可以缓解能源不足的压力,改善能源结构,更能有效改善经济发展与自然、环境之间的矛盾或冲突,实现经济的可持续发展.     

苗族的"蒙毕"和"蒙朵"——兼论文化人类学视野下的族群关系

以我国西部散杂区苗族内部两个族群的互动关系为视角,从文化变迁角度进行田野观察,可以得出这样的结论:即族群是在民族其下可再细分的文化变量;族群研究有学院派与田野派之分,二派之间通过采取不同的研究思路,意在更清晰地解读国内人类学学术研究范式的发展趋势。     

权力视角下的民族分层——以当代以色列为例

国际政治现实主义理论大师汉斯·摩根索指出:"由于人口多少是国家权力强弱的一个因素,由于一个国家的权力总是与他国的权力相关,争夺权力的各国之间的相对人口、尤其是人口增长的相对速度,便值得认真对待了."摩根索除了强调人口数量对一个国家权力的影响之外,还指出人口质量(民族性格、民族士气等)也是影响一个国家权力的重要因素.     

As low birth weight babies grow,can well-educated parents buffer this adverse factor? A research note

This research note combines two national Taiwanese data sets to investigate the relationships among low birth weight (LBW) babies, their parents' educational levels, and their future academic outcomes. We find that LBW is negatively correlated with the probability of such children attending college at age 18; however, when both parents are college or high school graduates, such negative effects may be partially offset. We also show that discrimination against daughters occurs, but only for daughters who were LBW babies. Moreover high parental education can buffer the LBW shock only among moderately LBW children (as compared with very LBW children) and full-term LBW children (as compared with preterm LBW children).

Survival Convergence and the Preceding Mortality Crossover for Two Population Subgroups

In this paper, we present and develop the argument that if the survival functions for two population subgroups converge in later life, a mortality crossover must precede the occurrence of this convergence. Specifically, two survival curves, S ₁(x) and S ₂(x), associated with two distinct population subgroups, G₁ and G₂, tend to converge before all members die out, as often observed and anticipated. This convergence leads to an increased mortality acceleration for the “advantaged” group, and eventually fosters the occurrence of a mortality crossover. We present a mathematical proof for this relationship and offer several explanations for the mechanisms involved in the process of survival convergence and the preceding mortality crossover. This new presentation demonstrates that mortality crossover is a highly observable demographic event given the trend of survival convergence in later life.     

Binary Dynamic Logit for Correlated Ordinal: estimation,application and simulation

We evaluate the estimation performance of the Binary Dynamic Logit model for correlated ordinal variables (BDLCO model), and compare it to GEE and Ordinal Logistic Regression performance in terms of bias and Mean Absolute Percentage Error (MAPE) via Monte Carlo simulation. Our results indicate that when the proportional-odds assumption does not hold, the proposed BDLCO method is superior to existing models in estimating correlated ordinal data. Moreover, this method is flexible in terms of modeling dependence and allows unequal slopes for each category, and can be used to estimate an apple bloom data set where the proportional-odds assumption is violated. We also provide a function in R to implement BDLCO.     

"雄王"、"雒王"之"雄"、"雒"考辨——从南越"雄鸡"木简谈起

有学者认为,《旧唐书》等文献中的"雄王"是从《水经注》中的"雒王"讹变而来,这种认识是不正确的.本文通过文献学和语言学的分析,认为2005年初广州出土南越木简中"雄鸡"简反映的命名特点与交趾地区"厥气惟雄"的风俗不仅地域上同在南越国境内,而且时代相同,应有紧密联系.南越木简的发现表明,《旧唐书》等文献中"雄王"的写法是正确的.
