如何正确评价原位饱和砂土的抗液化强度

依据剪切波速与抗液化强度相关性的原理,首先对某工程场地砂土地层进行了原位剪切波速测试和相应原状土样的室内剪切波速实验;然后以剪切波速为反映土体结构性的指标,定量评价了取样对抗液化强度的影响程度。剪切波速的对比实验表明,对于可液化深度范围内的砂土地层,室内测试剪切波速结果一般偏大,最大相差达40.7%,与此对应的饱和砂土的抗液化强度会增大到真实值的200%。因此不考虑取样过程的扰动而进行的原位饱和砂土地层抗液化强度的评价方法存在巨大误差。解决此问题的方法是以原位剪切波速为控制指标,在室内重现原位土层的抗液化强度。     

Management across boundaries: A municipal dilemma

Public sector mergers have the potential of being viable alternative to other public sector reforms in the striving toward making public service provision more equipped to confront some of the challenges faced today. Mergers however often fail to deliver promised results. Previous research point to the importance of post‐merger integrating processes for realizing the synergies expected from mergers. However, so far these studies have focused on what occurs inside organizations and less on the interplay between different levels. By adopting a governance and top management perspective, this study increases our understanding of the importance of political decisions on the outcome of a merger in the public sector context. Further, this study increases our understanding of how organizational boundaries on different levels of merging organizations influence post‐merger integrating processes and the role of different actors as boundary spanners. The results of this study are based on five case studies of public sector mergers at the local level in Sweden.     

毁灭与生存——《最蓝的眼睛》中佩科拉与克劳迪亚的命运对比

对比《最蓝的眼睛》中两个同为黑人社区贫穷家庭中的小女孩佩科拉与克劳迪亚截然不同的命运,从个人、家庭、社会三个角度分析造成两人完全不同命运的主要原因,可以看出莫里森的写作目的在于,向在文化冲突下的心灵扭曲的黑人群体指明找回自我的方向：正视黑人自己的文化与身份,重构完整的自我才是生存的必由之路。

The Social Pedagogy of Wall Street: Stock Trading as Political Activism?

In this paper, it is argued that the connectivity of the networked market permits market participants to perceive causal relationships between consumer behaviour and its effects on others. The thesis is put forward that the globally networked markets of the information age give birth to new cognitive structures that underlie consumers’ novel sense of responsibility, aid the re-orientation of consumers’ self-interest, and inculcate in consumers what historian Thomas Haskell calls humanitarian sensibility. Drawing from interviews with individual online investors, a model of the market is presented that posits the market as a source of social consciousness and moral decision-making. Furthermore, it is illustrated that individual online investors often incorporate such sensibilities into their consumer decision-making. Based on these results, the authors propose a corrective to the current trend among economists, social scientists and consumer researchers to conceive of the market as a threat to consumer autonomy, social and moral responsibility and an enlightened citizenry. Instead, it is asserted that the market has many faces, one of which, specifically the globally networked market, provides possibilities to recognize and perform consumption as a critical, moral and socially conscious political act.     

Resisting immigrant myths: everyday consumer practices of Asian immigrants in America

Projective, depth interviews with U.S. Asian immigrants revealed their ambivalence toward the U.S. commercial sector's colonial-era representations of Asian people. These commercial representations provide polarized depictions of Asian immigrants as either threatening aliens or as model citizens. These portrayals reflect “racialized otherness,” or racial stereotyping that represent Asian immigrants as inferior. Our findings indicate that Chinese immigrants strategically use everyday consumption related to foodways to resist the reverberation of American immigrant myths. In some instances, immigrants’ consumption practices instantiate a regional Asian identity. In other instances, however, immigrants’ consumption practices reflect a separation from the past and an acceptance of a new although not exclusively American way of life. Notwithstanding immigrant consumers' resistance practices, the findings call for future research into immigrant consumers' reactions to visual representations of race, ethnicity, and gender.     

Happy Festivus! Parody as playful consumer resistance

Drawing upon literary theory, play and consumer resistance literature, we conceptualize consumer parodic resistance – a resistant form of play that critically refunctions dominant consumption discourses and marketplace ideologies. We explore parodic resistance empirically by analyzing Festivus, a parody of Christmas. Festivus is found to be primarily constructed as a playful rejection of the established grand narratives and conventions of Christmas. In contrast to dominant Christmas ideology, Festivus promotes a grand narrative of “meaningful nothingness,” wherein Festivus celebration is presented a viable means of circumventing the oppressiveness of Christmas (i.e. “meaningful”) through erasing the higher goals and conventions if Christmas (i.e. “nothingness”). Our contribution is threefold: (i) we demonstrate the role of parody in consumer resistance; (ii) we outline the subversively playful nature of parodic consumer resistance; and (iii) we empirically demonstrate how parodic holiday celebration unsettles dominant discourses and conventions.     

An Alternative Lens for Understanding Technology Acceptance: An Equity Comparison Perspective

Many studies of technology acceptance have noted that new technology can have far-reaching effects, dramatically changing the environment (e.g., work, home, school) in which we use the technology. The current research considers an equity comparison perspective on technology acceptance and usage in the context of online discussion tools based on the equity implementation model (EIM). The EIM applies equity theory to assess user net outcomes related to adopting new technology in comparison to the net outcomes of other technology stakeholders. Facilitating conditions with the new technology are investigated as a moderating factor on intentions and usage. Equity theory and social comparisons provide an alternative lens for understanding technology acceptance that may capture broader issues related to the changes resulting from new technology. This research describes what we believe to be a first effort to operationalize social comparisons of equity in the context of technology acceptance. A survey instrument measuring social comparisons of net outcomes is developed, and a longitudinal, empirical study is conducted in the context of online discussion forums. The research model is also investigated within a nomological network of technology acceptance constructs. The results indicate that the model provides explanatory power comparable to existing models of technology acceptance and that outcome comparisons provide unique insight beyond known determinants of intentions and usage.
