高校学生群体性事件的预警与危机干预研究

伴随着我国社会经济发展、社会转型、社会关系多元化和教育改革,各种类型的高校学生群体性事件屡屡发生,对高校教学环境带来严重影响,甚至波及社会的和谐稳定。因此,要采取行之有效的应对措施。本文在分析了高校学生群体性事件新特征的基础上,从学生群体性事件危机管理的长效机制、网络舆情和校园文化三个维度进行探索,以便应对新形势下的高校学生群体性事件。     

共同富裕视域下三次分配的理论基础、本质要求及路径保障

在我国,三次分配是以马克思主义分配正义思想为理论指导,以社会主义按劳分配为分配原则,以第一次分配、第二次分配为分配基础,把第三次分配作为中国特色社会主义新时代收入分配制度体系重要组成部分的一种基础性制度安排,体现了社会主义的本质要求,是新时代落实以人民为中心的发展思想、使全体人民共同富裕取得更为明显的实质性进展的有效措施。本题以“社会公平正义”为价值原则,以“社会道德良知”为价值选择,以“社会共同富裕”为价值归宿,建构与阐明了中国特色社会主义新时代三次分配问题的基本共识,突出强调改善收入与社会财富分配上的最大公约数。三次分配以共同富裕为出发点和归宿也就决定了中国特色社会主义新时代三次分配必须遵从社会共同富裕的本质要求,明确社会主义核心价值观舆论导向,培育社会道德良知;加强政府对分配的监管,促进基本公共服务合理分配;深化分配制度改革,推进社会共同富裕逐步形成。     

分权与旅游治理:基于欠发达地区的实证分析

许多发展中国家实行高度的中央集权,学界对国家政治体制的集权化及其作用已经进行许多有益的探讨,但是对分权的利弊及存在问题却没有深入涉及。本文首先回顾区域治理中的分权理论,提出了一个权力配置、分权控制及其政治规范性的区域治理分析框架,用于描述国家权力在旅游治理中的运行机制,以北部湾旅游发展的实践为例,通过考察中央政府和地方政府、地方企业以及非政府组织在权力治理网络中成长态势,评估广西地方政府在区域旅游治理中的效力,研究发现地方政府在参与决策制定方面仍面临种种困难。     

美国历史上的黑白混血儿问题

黑白混血儿问题是美国黑、白种族关系史上一个很有意思的话题。在以混血为特征的美国社会,黑白混血儿不完全同于纯血黑人、也完全不同于其他混血儿的独特历史命运以及冒充白人的现象,既是对美国白人自认为血统纯正的讽刺,又揭示了建立在肤色基础上的种族歧视制度的脆弱性和荒谬性。     

制度自信:民族区域自治制度是解决当代中国民族问题的基本政治制度——“三个自信”与中国民族问题研究系列论文之四

民族区域自治制度的产生、发展与完善取决于我国的历史传承与现实国情,是中国共产党解决当代中国民族问题的基本政治制度.民族问题研究“去政治化”、第二代民族政策等观点的实质就是质疑乃至否定我国的民族政策和民族区域自治制度.坚持民族区域自治制度自信,就是要坚持“三是”、“两必须”、“三不容”的原则,从而促进各民族的团结,增强各民族的国家认同,维护国家领土和主权的统一.     

Benevolence-dominant,authoritarianism-dominant,and classical paternalistic leadership: Testing their relationships with subordinate performance

We propose a new typology of paternalistic leadership styles based on how leaders demonstrate authoritarianism and benevolence, the two essential components of this type of leadership. Benevolence-dominant paternalistic leadership refers to leaders' sole dependence on the use of benevolence without their strong assertion of authority, whereas authoritarianism-dominant paternalistic leadership is based mainly on authoritarianism itself; classical paternalistic leadership, which best fits early observations of paternalistic leaders, refers to the salient combination of both leadership components. We used two distinct samples and methods to test this typology and the association with subordinate performance. Across the two studies, a field investigation with Taiwanese military supervisor-subordinate dyads and a hypothetical scenario experiment with U.S. working adults, we found a positive relationship between classical paternalistic leadership and subordinate performance as strong as that between benevolence-dominant paternalistic leadership and performance. Our findings echo the phenomenon that paternalistic leaders tend to combine benevolence with authoritarianism to affect subordinate performance.     

Relation between the skew-rank of an oriented graph and the independence number of its underlying graph

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.     

A simpler PTAS for connected <Emphasis Type="Italic">k</Emphasis>-path vertex cover in homogeneous wireless sensor network

Because of its application in the field of security in wireless sensor networks, k-path vertex cover (\(\hbox {VCP}_k\)) has received a lot of attention in recent years. Given a graph \(G=(V,E)\), a vertex set \(C\subseteq V\) is a k-path vertex cover (\(\hbox {VCP}_k\)) of G if every path on k vertices has at least one vertex in C, and C is a connected k-path vertex cover of G (\(\hbox {CVCP}_k\)) if furthermore the subgraph of G induced by C is connected. A homogeneous wireless sensor network can be modeled as a unit disk graph. This paper presents a new PTAS for \(\hbox {MinCVCP}_k\) on unit disk graphs. Compared with previous PTAS given by Liu et al., our method not only simplifies the algorithm and reduces the time-complexity, but also simplifies the analysis by a large amount.     

资源型经济如何摆脱“资源诅咒”——基于中国的经验证据

我国资源型城市普遍存在着矿业、矿城、矿山、矿工"四矿"问题,并已严重制约了区域经济的可持续发展,这表明在我国城际层面"资源诅咒"效应也是成立的.将演化经济学作为分析资源型城市从"无序"到"有序"的方法论,可以发现,资源型城市摆脱"资源诅咒"需要具备投资规模、对外开放、技术创新和产业升级等方面的条件.对包头、攀枝花两座典型资源型城市的经济发展差距进行实证分析的结果表明,矿产资源会成为城市经济发展的"福音"还是"诅咒",关键取决于发展战略和发展模式的选择,因而,必须为我国的资源型经济提供科学的转型政策设计.     

反思"观念调查"

问卷调查要求回答的"单纯化"、"实验室化"与"标准化",可是"观念调查"基本上做不到这些要求,因此应该严格慎用之.作为补救措施,在设计原则上,提出了观念的持续期与观念的层次的概念,分析了观念调查结果的意义与主要用途.在操作层次上,提出7个具体的建议:高层观念的精确表述、调查道德观念的"讲故事法"、"照本宣科调查法"、弱化"对方指向"、慎用"假设式提问"、不要排序、不要"总汇".
