Occupy the government: Analyzing presidential and congressional discursive response to movement repression

I examine the role of Occupy Wall Street in shifting presidential and congressional discourse on economic fairness and inequality. Using data from 4646 presidential speeches and 1256 congressional records from 2009 to 2015, I test different mechanisms, including repression, media coverage, public opinion, and presidential agenda-setting by applying a novel combination of web scraping, natural language processing, and time series models. I suggest that movement success can be measured in its ability to shape discursive opportunity structures, and I argue that the role of the president should be at the forefront of social movements research. Ultimately, I demonstrate (1) that the repression of Occupy protesters not only predicts media coverage but also increases discursive opportunities through President Obama and Congress, (2) that media coverage of Occupy predicts presidential discourse, (3) that the president's rhetorical shift increases congressional response, and (4) that this change persists after the movement faltered.

Elementary renewal theorems for widely dependent random variables with applications to precise large deviations

Abstract

On the basis of Wang and Cheng (J. Math. Anal. Appl. 384 (2011) 597–606), this paper further investigates elementary renewal theorems for counting processes generated by random walks with widely orthant dependent increments. The obtained results improve the corresponding ones of the above-mentioned paper mainly in the sense of weakening the moment conditions on the positive parts of the increments. Meanwhile, a revised version of strong law of large numbers for random walks with widely orthant dependent increments is established, which improves Theorem 1.4 of Wang and Cheng (2011 Wang, Y., and D. Cheng. 2011. Basic renewal theorems for a random walk with widely dependent increments and their applications. Journal of Mathematical Analysis and Applications 384 (2):597–606. doi:10.1016/j.jmaa.2011.06.010.[Crossref], [Web of Science ®] , [Google Scholar]) by enlarging the regions of dominating coefficients. Finally, by using the above results, some precise large deviation results for a nonstandard renewal risk model are established, in which the innovations are widely orthant dependent random variables with common heavy tails, and the inter-arrival times are also widely orthant dependent.     

城市更新背景下的文化旅游发展研究——以广州为例

文化旅游的兴起是当今旅游业发展的一大趋势。城市更新是城市发展的一种重要途径。随着文化消费时代的来临、文化经济的快速发展,文化旅游在城市更新发展中扮演着日益重要的角色。本文主要以广州为例,探讨了城市更新背景下文化旅游发展的意义、面临的问题和挑战以及进一步的思考。     

建构一个新的城乡一体化分析框架：机会平等视角

对城乡一体化的现有研究或采用经济学视角,或采用制度学视角,而很少采用机会平等视角。研究认为:不论是经济资源配置还是制度和政策制定,都要视对城乡机会平等的影响如何,来判断其是否促进城乡一体化进程。机会平等是城乡一体化的本质属性。当然,机会是复杂、多样的,可以划分为基本生存机会、中层机会和高层机会,与此同时,平等也可以划分为形式平等和实质平等。在推进不同类型机会平等上,城乡一体化表现出不同的进度。该分析框架可以更好地分析我国城乡一体化进程(包括地区城乡一体化进程)。     

Mobilising diasporas for justice. Opportunity structures and the presencing of a violent past

ABSTRACT

This article investigates how the global dominance of the transitional justice (TJ) discourse and practice – and the controversies and conflicts that arise around TJ – have come to make up an important context for diaspora mobilisation. The article looks at the increasingly globalised mechanisms and norms of transitional justice as a set of opportunity structures – political, legal and discursive – which shape diaspora mobilisation. Diaspora engagement in commemoration, truth-seeking and legal justice in relation to atrocities in Rwanda and Sri Lanka is studied. The article shows that in relation to Rwanda, state dominance and divides are largely replicated in the diasporic space, while the Sri Lankan case provides examples of how Tamil diaspora engagement have been able to reverse power dynamics around TJ. Combining opportunity structures with the concept of ‘past presencing’, the article shows how diaspora groups appropriate and strategise in relation to the dominant norms and practices of TJ, and how in doing so the past is performed and experienced in ways which are both personally and politically meaningful.     

中国居民代际收入流动性的变化趋势及影响机制研究

基于1989~2015年共计10轮CHNS数据,本文采用代际收入弹性和代际收入秩关联系数双重测度指标对我国居民代际收入流动性进行了测算,发现代际收入流动性在1991~2004年期间基本保持稳定,2004年以后呈现出不断上升的变化趋势。基于收入分组视角的研究发现,各收入组2004年以后代际收入阶层固化程度均有所降低,但高收入组和低收入组的固化程度远高于其他各组,中等收入群体是目前我国保持较高代际收入流动性的主要动力来源。从城乡差异视角看,受大规模农村劳动力向城镇流动的影响,2000年后农村家庭的代际流动性显著提升,且持续高于城市居民的代际流动性。进一步,基于人力资本分析框架对我国代际收入传递机制进行了探究,发现父亲的非教育因素在代际收入传递中起到主导作用。受整体社会制度环境不断改善的积极影响,2004年以后非教育传递机制不断减弱,对代际收入流动性的提升起到较大助推作用;而受高等教育扩张政策的影响,教育因素在2004年左右一定程度上削弱了代际收入流动性。     

如何从生命周期理解我国的收入不平等

文章从生命周期的角度入手,以期为理解收入不平等提供一个不同的视角.基尼系数本质上衡量的是结果的不平等,收入所得税等政府政策也侧重对结果不平等的调整,但收入结果的不平等起源于机会的不平等,强化于过程的不平等,最终才表现为结果的不平等.机会不平等、过程不平等和结果不平等对应不同的生命周期阶段,需要不同的政策措施.对于机会不平等,政府应着眼于消除户籍制度等对不同人群的制度性歧视,减少我国区域发展水平的差距;推动幼儿和青少年教育与医疗服务的均等化,为他们创造一个公平的养教环境.对于过程不平等,一个重要的方面是建立对各种所有制员工和不同雇佣关系职工都公平的城乡统一的市场环境,消除劳动力市场中同工不同酬等歧视现象,尤其是取消国家制度和政策造成的劳动力市场分割.对于结果不平等,要兼顾公平和效率,在现有个人所得税、最低生活保障制度等基础上,逐步建立城乡统一、公平公正的收入调节和社会保障体系.     

信任对农民创业机会识别的影响

基于信任视角,构建农民创业者信任对创业机会识别的理论分析框架,运用链式多重中介方法,对浙江、安徽、河南和陕西4省880份农民创业者访谈数据进行实证分析,结果发现:信任能显著提高农民创业机会识别;农民创业者信任能通过外部知识获取与创业警觉性对创业机会识别产生间接影响,其作用路径有三条:外部知识获取的部分中介作用、创业警觉性的部分中介作用及外部知识获取与创业警觉性的链式中介作用。因此,政府应完善农民创业相关规章与制度;推进农村文化建设,提高信任水平;增加农民创业知识与技能的供给,培养农民创业者的机会警觉性。     

两种理论视野下的西欧穆斯林政治参与问题探析

20世纪60年代以来,穆斯林已经成为西欧社会不容忽视的现实存在,但是在政治参与方面,穆斯林远未能有效参与西欧各国的政治进程。穆斯林人口在种族、经济地位等方面的多样性是其有效参与政治的内在障碍。从资源动员理论和政治机会结构理论的分析可以发现,穆斯林对公民权、政治精英、参政渠道等政治资源的占有不足,加之欧洲殖民心理遗产的影响、欧洲的世俗化政策、伊斯兰恐惧症、外部穆斯林世界的影响等多种因素,共同构成了影响穆斯林广泛参与西欧政治生活的重要原因。
