苏丹贝贾部落的历史演变与现状困境

贝贾部落的历史可追溯至4000年前,他们以畜牧业为主,生活在苏丹东部地区,其身份标识是托贝达维语、迪瓦卜体系与斯里夫制度。苏丹在土埃共管、英埃共管以及独立之后等历史时期,不同的统治者们给贝贾部落造成土地流失、赋税压榨、传统式微等多种消极影响。2006年《苏丹东部和平协定》签订后,占东部地区人口半数的贝贾部落处于新的困境当中,由此产生了潜在的分裂意识。当今贝贾部落及苏丹东部的隐性问题,其原因是各时代的历史痼疾积累与边缘化政策延续的结果。     

No Room for Respectability: Boundary Work in Interaction at a Shanghai Rental

This article examines the dramaturgical challenges of doing boundary work for a group of college women living with non‐college women at an overcrowded rental. To regulate tenant conduct and maintain their sense of self‐worth, the college women engaged in defensive othering and constructed their identity as “high‐quality” people on the basis of their characterization of their less‐educated roommates as “low‐quality” people. Their strategy of gaining self‐worth at their roommates' expense violated basic rules of social interaction that require participants to give face to gain face. This study shows that, in addition to weakening group solidarity and reproducing social inequalities, defensive othering also undermines subordinates' effort to gain self‐worth in the co‐presence of other subordinates.

Determinants of public attitude towards a social enterprise crisis in the digital era: Lessons learnt from THINX

This study examines how the perceived locus of crisis cause, controllability, and adherence to social mission are associated with public attitude in the context of a social enterprise crisis and evaluates the differences between these variables under episodic and thematic frames of online articles. Using the crisis case of THINX in 2017 as a case study, a quantitative content analysis was performed on a sample of 503 comments under online articles. Hierarchical regression revealed that the locus of crisis cause and adherence to social mission were associated with public attitude, whereas controllability was not associated with public attitude when adherence to social mission was accounted for. Significant differences were found in the locus of crisis cause, controllability, adherence to social mission, and public attitude between episodic and thematic frames. This study provided a basis for the theoretical development of crisis communication in a social enterprise and the corresponding role for public relations.     

詹姆斯·威尔逊与美国早期联邦制的演进

美国早期联邦制的演进是各种联邦制观点相互竞争和谈判的过程。詹姆斯.威尔逊的联邦制观点是其中最重要的一种。从美国独立战争前的政治辩论到1787年联邦宪法的制定和批准,威尔逊以他对政治理论和实践的深刻认识,阐释了整体与部分的关系及各自的权力和职责,从而在美国早期联邦制的演进过程中,扮演了重要的角色。     

保护和开发青海农村文化资源探析——以湟中县鲁沙尔镇的民间手工制造业为例

青海著名旅游胜地塔尔寺所在地湟中县鲁沙尔地区拥有源远流长、多民族融合、色彩斑斓的民间手工制造业文化资源。通过对湟中县鲁沙尔镇的民俗文化资源考察发现,由于多种原因,一些民间手工制造业文化资源尚未得到保护和开发。因此,利用农村文化资源发展文化产业,一定要处理好农村文化资源的保护和发展特色文化产业的关系,才能实现民俗文化与文化产业的双赢。     

欧盟一体化过程给我们哪些启示

珠江三角洲经济一体化涉及到不同城市和地区之间的利益分配,涉及到区域资源共享、产业合作、市场开拓、基础设施合作等诸多领域的问题,是我国区域合作与发展中的一个新尝试.也将是东、中、西部经济互联互动、协调发展的新突破,有可能成为中国区域经济发展的一个新范式.欧盟区域经济一体化是世界上公认的比较成功的发展模式.虽然欧盟经济一体化是在一个超国家的政治格局下进行的.而珠三角一体化是在一个主权国家政治下开展的,但作为"区域经济一体化",两者之间存在着诸多相似之处.欧盟在一体化过程中实施的产业政策、区域政策、基金政策、贸易政策等各项政策和具体做法都有很多值得学习和借鉴的成功经验.     

我国户口迁移制度弊端与改革刍议

随着社会的发展,户口迁移制度的弊端日益显现,具体表现为：制约了经济统筹协调发展;严重妨害了人力资源的优化配置;延缓了城市化进程;导致产生腐败;影响了社会公正等。当前,改革户口迁移的经济条件和政策条件已经具备,改革的总体思路是：新建、发展新城市群和小城镇,就地、就近转化农业人口为城市居民;采取经济、市场等多种有效措施引导人口合理有序流动;按照因地制宜、循序渐进原则逐步放宽户口迁移限制等。

Conditional variance estimation in heteroscedastic regression models

First, we propose a new method for estimating the conditional variance in heteroscedasticity regression models. For heavy tailed innovations, this method is in general more efficient than either of the local linear and local likelihood estimators. Secondly, we apply a variance reduction technique to improve the inference for the conditional variance. The proposed methods are investigated through their asymptotic distributions and numerical performances.
