土耳其与伊朗关系演变的内外因素分析

作为中东地区两个主要大国,土耳其和伊朗的关系长期以来因为伊斯兰世界领导权、地缘政治影响、少数民族动乱、政治模式差异等一系列因素,处于一种结构性矛盾之中。近年来,随着中东地区政治环境的变化,再加上其自身内部政治变革、经济困境和政治伊斯兰思潮等因素的作用,两国关系出现了明显改善。土伊关系的改善对于平衡美国势力对中东地区的干预和维护地区和平稳定具有重要的积极作用。但由于结构性矛盾难以克服,两国关系的未来发展依然取决于该地区内外环境的变化。     

“上下分合轨迹”:社区空间的生产——关于南苑肿瘤医院的抗争故事

本文聚焦于南苑①围绕广安肿瘤医院的抗争故事,将该事件置于城市空间重构与生产的结构性情境下,分析社区空间的生产机制。文章指出,自上而下的空间规划权力在执行过程中隐蔽在市场化的话语体系下,以程序合法性及产权的话语获得垄断地位;而自下而上的抗争以规则、权利等意识为主导,通过"间隙运用"的策略生产出社会空间,但最终服从于空间的霸权体系。作者分析了空间霸权的战略、空间抗争的战术特点,以及上下分合轨迹,将其统合成为社区空间的生产过程。笔者认为,社区空间应该趋向对社会主义空间的生产,才能更好地实现空间正义。

伊拉克"后重建时期"的库尔德分离主义新危机

随着美军2011年撤退期限临近,伊拉克即将进入一个没有美军直接干预的"后重建"时代。与此同时,伊拉克库尔德人的分离主义危机也再次出现。究其原因,主要是美国政府干预下伊拉克建立的"合作性民主"制度缺乏内在凝聚力,伊拉克阿拉伯民族主义者强调中央集权和反对联邦制宪法的倾向威胁到库尔德人的自治,伊拉克国内不同种族和宗教派别之间因核心利益差异而导致的各种冲突难以和解,还有库尔德斯坦自治以来与周围国家地缘政治关系的有利改变。这些因素都为库尔德人争取独立提供了重要契机,从而使得伊拉克库尔德分离主义危机再次成为国际社会关注的焦点。     

Video primacy—A further look

This paper reviews the literature on the complex question of the relative importance of the verbal, visual and vocal channels in various types of judgments. It is noted that a wide variety of methodologies are used in such research with studies differing in terms of the type of stimuli used (varying on the dimension of stylised to naturally occurring), the task required of the subjects (particularly varying on the cognitive-affective dimension) and the method used to assess the relative importance of the channels. An attempt is made to assess the important variables which affect the way the various channels are used by decoders, including whether deception is involved or expected, whether the message is discrepant, the particular judgment being made and the dimension on which the stimulus varies, the sex of the encoder and the decoder and the relationship between them, and the age of the decoder. The possibility of other related variables also acting as moderators is discussed.     

Mapping of noise impact provoked by the execution of foundation piles at high rise building sites

The objective of this work is to map, in a limited area inside and outside of the worksite, the environmental impact generated by sound pollution coming from the driving of foundation piles for high rise buildings, as well as to observe and check if the noise levels produced by the emitting source are tolerable in the urban environment. The methodology of the work includes a survey of technical references about the subject; measurement of noises surrounding the worksite during the foundation phase for four distinct buildings, with different types of piles: prefabricated piles, continuous helical displacement piles , traditional compaction piles and Terra Probe compaction piles. A grid of points was built due to the time of driving and after that the measurements of environmental noises were performed emitted by the execution of each type of pile using a sound level meter. The interpretation of the measurements and their impacts on the neighborhood of the building were performed using the computational tool Suffer for creating noise level contours. The X and Y axes of the grid represent the distances in meters of the area studied and the Z axis represents the noise measured in dB. The contours developed represent the mapping of the noise at the worksites and their surroundings. The mapping of the urban impact of noise, the measurement of its dimensions, and the examination of its propagation around the building are important subsides to adequate individual and collective protection procedures. Seventy one points were measured at four building sites with different types of piles, and the results showed that at only three points was the noise within the limits of the Municipal Law of Recife of 70 dB, which proves the relevance of the research. Finally, the comparative analysis between the four types of piles shows that the continuous helical displacement pile emits the lowest noise level among the four pile types studied.

Vision and Mission of Sociology: Learning from the Russian Historical Experience

The present study demonstrates that the path of the “organic public sociology” (proposed by Michael Burowoy in his famous call of the 2004) as the dominating mode of sociological practice in the national context can be menacing with the serious pitfalls manifested in broad historical perspective. We reveal the four pitfalls basing on the analysis of the Russian experience through the last 150 years. First, the over-politicization and ideological biasness of sociological activities; second, the “personal sacrifice” of sociologist as a romanticized practice, potentially harmful for the discipline; third, the difficulties of the professional sociology institutionalization; fourth, the deprivation of the policy sociology development. Analyzing the history of Russian sociology in the context of the current international discussions, we give particular reference to the idea of the “Scientized Environment Supporting Actorhood” elaborated by John Meyer. We suggest the mode of communication between sociology and society, which, in our view, could be helpful for improving their interactions in various local, national and global contexts in the XXIst century. This mode escapes the political emphasis and ideological claims but rather concentrates on the more fundamental ethical issues. It also tries to overcome the limitations of the contemporary professional mainstream (instead of idealizing it). Finally, it presents itself to the publics in the understandable way, while remaining properly scientifically validated (however, avoiding the exaggerated accent on the statistical procedures and fitishization of the natural science’ principles (“numerology” and “quantofrenia”)). The public activities of the prominent sociologist Pitirim Sorokin in the American period of his career are a good example of this approach to the interactions with society.     

Relationships between rural inhabitants and their landscapes in areas of intensive agricultural use: A case study in Quebec (Canada)

An understanding of the relationships between local populations and the landscape is crucial for reintroducing the multifunctional character of landscapes in areas of intensive agricultural use. This study proposes to identify and compare the relationships that local populations, both farmers and non-farmers, maintain with their landscapes in areas of intensive agricultural use based on a detailed case study in Quebec, Canada. It relies on the dialectical conceptual model of individual–landscape interactions and introduces the notion of “community of relationships to the landscape” to compare populations. Following semi-structured interviews, we performed an analysis of the links between the attributes of the valued landscape, the motives for having those values and the practices tied to those values. This led to distinguish between four main types of relationships with the landscape: the hedonistic relationship, the emotional relationship, the utilitarian relationship, and the relationship with the social environment. Then, on the basis of the relative weight of each relationship and the interactions between the multiple relationships that local inhabitants have with the landscape, four communities of relationships to the landscape were identified, most including both farmers and non-farmers. Beyond the apparent uniformity of the landscapes in areas characterized by intensive agriculture, the results highlight the diversity of the local populations and confirm the heuristic significance of the notion of community of relationships to the landscape. Finally, our analysis of the differences with regard to values and visions between the communities suggests that the vitality of these rural areas can only be ensured by recognizing, maintaining and possibly increasing the current diversity of communities.     

Fighting in the Dark: Ideology and State Formation in Post‐Colonial Burma

Extant major approaches to states and revolutions privilege the role of state practices and the character of war‐making in shaping modern state‐making in the Third World. Bringing the role of ideology into this analytical landscape of state‐making, this paper advances an alternative claim that ideological practices shape modern state structures and practices as well as the dynamics of political contention between the state and the revolutions. First, I argue that that intra‐movement ideological dynamics within the nationalist movement can have a profound impact on the structure and practices of the state. Using the writings of the party leaders, memoirs and official publications of the Burmese communist party, I maintain that subtle and specific ideological differences amongst the Burmese leftist movements generated organizational splits and internecine conflicts in the nationalist struggle, which exerted profound influences on the structures and practices of the Burmese state Secondly, relative ideological positions of the state and the revolutionary movements play an important role in shaping the dynamics of contention between the state and revolution. For example, an intimate web of ideological affinity between the nascent Burmese state and the Burmese leftist movements shaped the context and content of political contention between the state and these movements in the post‐colonial Burma. To address these issues empirically, the first part of the paper examines the formation and cementation of organizational linkages amongst Burmese leftist nationalists during the anti‐colonial struggle. The second part of the paper addresses specific and subtle ways in which ideological character and practices of the Burmese state and the Burmese Communist party shaped state practices and state structures in modern Burma as well as the dynamics of political contention between the state and the revolutionary movements.
