A probabilistic clustering method for data elements with normal distributed attributes

By considering uncertainty in the attributes common methods cannot be applicable in data clustering. In the recent years, many researches have been done by considering fuzzy concepts to interpolate the uncertainty. But when data elements attributes have probabilistic distributions, the uncertainty cannot be interpreted by fuzzy theory. In this article, a new concept for clustering of elements with predefined probabilistic distributions for their attributes has been proposed, so each observation will be as a member of a cluster with special probability. Two metaheuristic algorithms have been applied to deal with the problem. Squared Euclidean distance type has been considered to calculate the similarity of data elements to cluster centers. The sensitivity analysis shows that the proposed approach will converge to the classic approaches results when the variance of each point tends to be zero. Moreover, numerical analysis confirms that the proposed approach is efficient in clustering of probabilistic data.     

‘Having to say everyday … I’m not black enough … I’m not white enough’. Discourses of Aboriginality in the Australian education context

This paper interrogates discourses of Aboriginality about, and by, early career Aboriginal teachers as they negotiate their emergent professional identity in specific Australian school contexts. These discourses position the respondents via their ethnic and cultural background and intersect with self-positioning. This relates to the desire to be positioned as teacher rather than (only) as an ‘Aboriginal’ teacher. Consequently, the over-determination of Aboriginality includes such suppositions as the ‘think-look-do’ Aboriginality with a ‘natural’ connection to community, the ‘good’ Aboriginal teacher who fixes Aboriginal ‘problems’, the Aboriginal teacher as ‘Other’, and [the notion that] ‘Aboriginal work’ as easy, not real work and peripheral to core business. Through qualitative methodology, eleven Aboriginal teachers from the University of Sydney were interviewed. They were able to construct stories of early career teaching and the data was analysed to explore how the participants interpreted, accepted and/or resisted various discourses in their efforts to be agentic and resilient and to make a difference for the Aboriginal students they teach.     

The Nature of the Political Reconsidered

I present an immanent, and explanatory, critique of reflections on the nature of politics and of power within political science. I argue that these reflections are problematic, to the extent that they presuppose an actualist conception of the political, and that this is generated by an empiricist way of thinking on the one hand and a constructivist way of thinking on the other. I show how re‐defining politics, power, and the political on the basis of a dialectical critical realist ontology resolves these problems and, thereby, allows us to understand the conditions for social change and the relationship between the political and the economic. My argument has two, important implications: first, that the proposal that those who study politics professionally should celebrate philosophical diversity is dangerous–at least if it makes it difficult to sustain a distinct, emancipatory form of political inquiry; and, second, that the nature of social reality justifies the need both for specialized forms of inquiry, such as politics and economics, and integrative forms of inquiry, such as political economy.     

监察委员会人事管理与约束监督刍议

《监察法》的出台标志着监察制度改革的成果在法律层次上的确认,是国家在政治体制上进行顶层设计的一件大事。“一府一委两院”的政治新格局初步形成,深化监察制度改革依然是健全完善国家监督体系的重要路径。监察委员会的出现不同以往政治体制的改革,使行政监察迈向国家监察,监察制度实现了质的飞跃,其人事管理和“超级机关”的潜在威胁是不容忽视的。基于法治建设中具有普适价值的独立性与权力制约两原则,从人才选拔、人事培养到人事考核探索监察委员会的人事管理,从党的领导和外部机关约束监督的视角思量监察委员会的被监督问题。     

Celebrating Joan Acker: Sociologist,fearless feminist,friend

Joan Acker's life reflects a time when middle‐class women were expected to be satisfied with maintaining the home front, serving husbands and children, not having paid‐work careers. After living “the ideal” for 37 years, Acker took a new path by earning a Ph. D. and producing path‐breaking scholarship that challenged taken‐for‐granted beliefs about gender, family, work, and organizations. Acker spoke “truth to power” and was an academic heroine in posing feminist challenges to injustices involving gender, social class, and race/ethnicity, particularly (but not solely) related to the workplace. This overview lets Joan tell her story and offers reflections on her milestone publications as seen by Pat Martin.     

政治权力的反思与重构——基于女性主义国际关系理论视角

政治权力是政治学与国际关系等社会科学中的一个核心概念,其中权力可以视作手段、目的、关系过程与行为结果。女性主义国际关系理论对政治权力的认识、发现并批评了古典政治哲学与现实主义政治权力观的不足,在再认识的基础上,对政治权力的载体、目标和话语等进行了深刻反思,相应地从内涵、认知、目标等方面对政治权力进行重构。本文认为,政治权力的主体价值,是使政治权力的领导者构成得以重塑,而女性主义国际关系理论则推动了区域化与全球治理进程,促进了国际关系民主化。     

Pricing power options with a generalized jump diffusion

In this article, the valuation of power option is investigated when the dynamic of the stock price is governed by a generalized jump-diffusion Markov-modulated model. The systematic risk is characterized by the diffusion part, and the non systematic risk is characterized by the pure jump process. The jumps are described by a generalized renewal process with generalized jump amplitude. By introducing NASDAQ Index Model, their risk premium is identified respectively. A risk-neutral measure is identified by employing Esscher transform with two families of parameters, which represent the two parts risk premium. In this article, the non systematic risk premium is considered, based on which the price of power option is studied under the generalized jump-diffusion Markov-modulated model. In the case of a special renewal process with log double exponential jump amplitude, the accurate expressions for the Esscher parameters and the pricing formula are provided. By numerical simulation, the influence of the non systematic risk’s price and the index of the power options on the price of the option is depicted.     

治理的发轫与嬗变：中国历史视野下的考察

国内学术界一般以西方学术发展史作为背景，把治理作为一种社会互动来进行研究。中国历史视野下的治理，发轫于中国社会生活，其内涵最初主要是为了获取生存资料，即有收成才能够形成秩序也就是治理。从“乂”这个象形文字来看，乂就是治理，其原意为“收割”。不过，围绕生存资料的生产和分配逐渐产生了更加丰富的社会权力关系，而巩固和拓展这种权力关系则使得构筑更加严格的秩序成为必然。神秘感是构筑秩序的重要依据，而赋予仪式以神秘感的则是觋、巫等知识群体，他们将天、帝、王、人通过仪式联系在一起，建构起一套以礼为基础的秩序。但是，西周末年，觋、巫的神秘感被世俗的君权摧毁以后，“君臣秩序”以及由此构筑起来的社会秩序都被颠覆，从而导致“君臣之礼既坏”和“礼坏乐崩”的情形。“以智力相雄长”不仅表现在王室内部、诸侯之间、社会层面上，而且也表现在知识分子身上。从此以后，士绝大多数以追逐爵禄而骄天下为荣，以至于两千多年来一直存在“士贱而君肆”的情形。“君士互动”的治理模式，正是随着神秘主义的礼的崩溃而崩溃的。     

中国发展道路:条件、原则、方式与未来——一个规范性的解释框架

改革开放以来,中国经济取得了高速增长,工业化、市场化、城市化、国际化以及社会、政治、知识等方面也都发生了重大变化。文章主要从规范分析的角度,首先辨析了中国发展的"模式"与"道路"的概念差异,提出界定发展模式的三个判断性标准;进而从发展的构成要素、基本原则、实施方式等角度总结出中国的发展经验;由此逐步分析中国发展的三类约束性条件、中国发展道路所内含的四项基本原则及中国发展的四种主要实施方式;最后提出未来中国持续发展的困难和愿景。     

司法附属行政语境下的中国古代法官地位

“司法附属行政”是中国古代司法的一个重要特征。在这一背景下，中国古代法官地位就呈现出鲜明的附属性特征，这种特征同样体现在法院的地位和司法权的地位上，这也导致中国古代法官没有专门的职业保障制度，而这一切都深深地镶嵌在当时的人治大背景之中。通过与现代法官地位的比较，可以更加深切地感受到古今法官地位以至整个司法状况的巨大差异。中国现代法官地位在独立性方面相对于古代法官有了巨大改善，但仍然不尽如人意，还需要在今后的司法改革中进行反思和重点关注。
