论普里什文哲理散文中的生态文学思想与猎人情结

普里什文哲理散文中所具有的预言式生态思想与环保理念备受当代“生态文学”理论家的青睐。但他热衷描写狩猎场景的猎人情结却又遭到新世纪中“生态伦理”理论的诟病。其实从文本的本体性观念来理解，普里什文的诗性自然情怀、生态观念与他的猎人情结并非只有冲突的一面，他所表达出的是人对大自然万物之本能与道义之间的尺度衡量，而这种衡量也可反观当代人与自然万物之间的关系的现状，实际上表达出一种更为深刻的天人关系的批判性。     

“草根”情节和“乡愁”意识折射出的断层社会

从贾樟柯导演的第一部长片电影《小武》开始,其作品多次在各大国际电影节上斩获大奖,这与他坚持以现实主义风格创作是分不开的。他始终用冷静的思维和镜头语言,关注边缘人物的命运,描绘着这个真实世界所发生的故事。文章深入分析其电影《世界》抽象的叙事空间所要揭示的内涵,指出在“草根”情节和“乡愁”意识下,人在寻找自我和社会归属的同时迷失方向,从而对社会产生一定的反作用力而导致了社会的“断层”。

论中国文人的"巫山神女情结"

本文对中国文人"巫山神女情结"及其产生的原因作了多角度的透视,并对两千多年纷繁复杂的"巫山神女情结现象"作了认真的梳理和初步分析,认为"巫山神女情结"是宋玉的复杂心态与大礼教文化语境碰撞的产物,其心理实质是"后俄狄浦斯情结";"巫山神女情结现象"则是"菲勒斯"中心主义男权话语的集中体现,反映了男性文人潜意识中对受礼教压抑的本色人性的深深眷恋,是集体无意识的象征性显现.     

A model for collaboration networks giving rise to a power-law distribution with an exponential cutoff

Recently several authors have proposed stochastic evolutionary models for the growth of complex networks that give rise to power-law distributions. These models are based on the notion of preferential attachment leading to the “rich get richer” phenomenon. Despite the generality of the proposed stochastic models, there are still some unexplained phenomena, which may arise due to the limited size of networks such as protein, e-mail, actor and collaboration networks. Such networks may in fact exhibit an exponential cutoff in the power-law scaling, although this cutoff may only be observable in the tail of the distribution for extremely large networks. We propose a modification of the basic stochastic evolutionary model, so that after a node is chosen preferentially, say according to the number of its inlinks, there is a small probability that this node will become inactive. We show that as a result of this modification, by viewing the stochastic process in terms of an urn transfer model, we obtain a power-law distribution with an exponential cutoff. Unlike many other models, the current model can capture instances where the exponent of the distribution is less than or equal to two. As a proof of concept, we demonstrate the consistency of our model empirically by analysing the Mathematical Research collaboration network, the distribution of which has been shown to be compatible with a power law with an exponential cutoff.

Morality and politics: Comparing alternate theories

Debates about the American “culture wars” have led scholars to develop several theories relating morality to political attitudes and behaviors. However, researchers have not adequately compared these theories, nor have they examined the overall contribution of morality to explaining political variation. This study uses nationally representative data to compare the utility of 19 moral constructs from four research traditions – associated with the work of Hunter, Lakoff, Haidt, and Schwartz – for predicting political orientation (liberalism/conservatism). Results indicate that morality explains a third of the variation in political orientation – more than basic demographic and religious predictors – but that no one theory provides a fully adequate explanation of this phenomenon. Instead, political orientation is best predicted by selected moral constructs that are unique to each of the four traditions, and by two moral constructs that crosscut them. Future work should investigate how these moral constructs can be synthesized to create a more comprehensive theory of morality and politics.     

Framing strategy under high complexity: Processes and practices of ongoing reframing in the becoming of strategy

Framing is a key concept in research on how strategists legitimize and win support for strategic change by establishing a frame of reference for that change. This article advances research on strategy framing by showing how, under conditions of high complexity and uncertainty, strategists continuously reframe strategy in relation to shifting constellations of stakeholders. It presents the findings of an ethnographic study of strategizing in the highly complex context of the digital transformation journey of a global manufacturing firm. It shows how (re)framing practices are combined to iteratively shape strategy formation in ways that sustain strategic influence in the face of constant threats to legitimacy. By accounting for how (re)framing practices reach back and forth in time, the ethnographic findings refine the conventional understanding of how framing resources of past strategizing enter and reworked in present strategy work. Finally, the article contributes empirical insights into how information systems specialists, often marginalized as strategic actors, frame and pitch strategic projects to gain and exert influence in strategy formation processes.
