Exploring the intersection of transnationalism and critical race theory: a critical race analysis of international student experiences in the United States

International student mobility to the United States (US) has increased over the past two decades. Despite the increase in numbers, international students may experience racism, nativism, and other forms of discrimination within the US context. Much of the existing literature focus on how international students can assimilate and cope with these issues rather than interrogating the systems of oppression that create negative student experiences. Thus, we utilized critical race theory (CRT) as a framework for interrogating how international student experiences are portrayed in current literature. Although CRT is grounded in US-based legal theory, we argue that CRT must move beyond the rigid confinement within US borders and expand to consider how transnationalism and global exchange contributes to the fluidity and applicability of this theory. We also provide recommendations for critical race praxis, with an emphasis on implications for practice, theory, and future research.     

信仰食物：祭品的神性“营养”

基于学界饮食文化意义本身研究的丰硕成果,以宗教人类学的视角对物质文化进程中的食物信仰性进行探究.专就族群赖以生存的基本食物的文化属性详加分析,窥探其在体制性宗教信仰与民族民间宗教信仰文化观念的建构过程中,表现路径之不同和所承载的重要作用.无论是体制性宗教的特殊标志,还是民族民间宗教信仰中以祭品加以改造的方式,都相当程度阐释出信仰食物在与神灵互通实践中的精神营养内涵,以及于此两种文化信仰氛围之下的饮食男女的意义关系.     

Parameterized algorithms for min–max 2-cluster editing

For a given graph and an integer t, the Min–Max 2-Clustering problem asks if there exists a modification of a given graph into two maximal disjoint cliques by inserting or deleting edges such that the number of the editing edges incident to each vertex is at most t. It has been shown that the problem can be solved in polynomial time for \(t<n/4\), where n is the number of vertices. In this paper, we design parameterized algorithms for different ranges of t. Let \(k=t-n/4\). We show that the problem is polynomial-time solvable when roughly \(k<\sqrt{n/32}\). When \(k\in o(n)\), we design a randomized and a deterministic algorithm with sub-exponential time parameterized complexity, i.e., the problem is in SUBEPT. We also show that the problem can be solved in \(O({2}^{n/r}\cdot n^2)\) time for \(k<n/12\) and in \(O(n^2\cdot 2^{3n/4+k})\) time for \(n/12\le k< n/4\), where \(r=2+\lfloor (n/4-3k-2)/(2k+1) \rfloor \ge 2\).     

国内外广告产业统计范围的比较

广告产业统计为广告产业发展的基础性研究课题,同时是政府进行广告产业的财政统计的依据与标准以及实现国际相同产业发展对照的基本标准.我国现行的广告产业统计标准多年来未经调整修正,不能真实反映产业发展实际.文章通过综述国内外相关学术研究,并结合我国现行的《广告业统计报表制度(2012)》、《国民经济行业分类(GB/T4754-2011)》、联合国颁布的《所有经济活动之国际标准行业分类(修订4版)》与《北美产业分类体系(2012)》当中广告产业的统计分类与统计范围,总结我国现行的广告产业统计分类标准存在的主要问题,即产业界定、定位与广告产业现实发展偏离;产业分类方式滞后;产业统计范围狭窄且有重合之处.     

交通基础设施、空间溢出与经济增长关系的实证分析

文章构建中国2000-2015年间30个省份多样化的空间面板数据,采用极大似然估计、空间杜宾模型及偏微分方法,实证测度了中国交通基础设施对经济增长的空间溢出效应.研究发现,铁路在地理距离作用下对经济增长正向显著,在其他作用下不显著;公路在经济、产业和技术距离作用下高度显著,而在地理距离作用下不显著.综合距离作用分析表明,公路对经济增长存在积极的溢出效应,在统计上正向显著;而铁路则存在较弱的影响,且未通过显著性检验.     

基于格兰杰因果关系检验的ISM改进与应用

文章提出了一种基于格兰杰因果关系检验的解释结构模型(ISM)改进方法,该方法能依据客观统计数据识别影响因素的两两关系,进而改善了原有模型中采用专家评价法确定邻接矩阵的主观性困境.通过对物流与经济协同发展水平的影响因素分析,实证检验了解释结构模型改进方法的可行性.     

中国城乡发展差距水平及其波动效应的实证

城乡发展差距是中国社会转型下最突出的矛盾之一.文章从经济、社会、文化、政治、生态五大维度构建中国城乡发展差距综合评价指标体系,以中国31个省份为研究区域,运用主成分分析法实证评价了中国城乡发展差距的现实水平及其波动效应.研究表明,中国城乡差距水平由东向西呈递增趋势,1985年至今城乡差距水平表现为一种波动性扩大的效应,城乡差距水平与城镇化发展水平表现为一种相互影响的逆向关系.     

固定设计异方差非参数回归模型的预测方法

文章针对固定设计下异方差非参数回归模型,考虑了基于多项式样条的三种预测方法,即非外推法、线性外推法和非线性外推法.模拟结果表明非外推预测法的均方根误差(RMSE)和平均绝对误差(MAE)的均值最大,而线性外推法的RMSE和MAE的均值略小于非线性外推法的RMSE和MAE的均值.实证分析结果显示:非外推预测法的平均绝对百分比误差(MAPE)、RMSE和MAE最大,线性外推法的MAPE、RMSE和MAE最小.这表明整体上外推法优于非外推法,而线性外推法是简单可行的.     

Public Attitudes towards Income Redistribution: Evidence from Hong Kong

The drivers of public support for redistributive policy have stimulated academic debate around the world. The majority of studies use cross‐country surveys conducted in the Organisation for Economic Co‐operation and Development countries to contribute to the debate on whether self‐interest or social values have more influence on public attitudes towards redistribution. Drawing on a phone survey conducted in 2013, this study advances the discussion by investigating public attitudes towards redistribution and social policy changes against the backdrop of buoyant government revenues in Hong Kong. The Hong Kong welfare model, best seen as a parallel to the liberal welfare state, is selective and residual. Contrary to the usual assumption, the social values hypothesis, viewing poverty as societal problems instead of individual reasons, has been supported in the Hong Kong context. It lends support to greater redistribution in a residual welfare state. The policy implications of the findings are also discussed.
