审美现代性之"新奇"观的蜕变--从波德莱尔、阿多诺到罗兰·巴特

自波德莱尔以来,"新奇"成为审美现代性的核心范畴之一.波德莱尔之"新奇"是指艺术家对瞬间呈现的美的捕捉,它标识着主体的"独创性";阿多诺把艺术对"新奇"之物的渴求,规定为艺术对抗物化现实的"动能"和策略;罗兰·巴特的"新奇"则是指"文"的生产性.通过对"新奇"的意义之蜕变的考察,透视出审美现代性展开的脉络及其危机.     

A Method for Measuring Distance From a Training Data Set

A new method is proposed for measuring the distance between a training data set and a single, new observation. The novel distance measure reflects the expected squared prediction error when a quantitative response variable is predicted on the basis of the training data set using the distance weighted k-nearest-neighbor method. The simulation presented here shows that the distance measure correlates well with the true expected squared prediction error in practice. The distance measure can be applied, for example, in assessing the uncertainty of prediction.     

Multivariate Control Charts Based on Hybrid Novelty Scores

We propose a new nonparametric multivariate control chart that integrates a novelty score. The proposed control chart uses as its monitoring statistic a hybrid novelty score, calculated based on the distance to local observations as well as on the distance to the convex hull constructed by its neighbors. The control limits of the proposed control chart were established based on a bootstrap method. A rigorous simulation study was conducted to examine the properties of the proposed control chart under various scenarios and compare it with existing multivariate control charts in terms of average run length (ARL) performance. The simulation results showed that the proposed control chart outperformed both the parametric and nonparametric Hotelling's T ² control charts, especially in nonnormal situations. Moreover, experimental results with real semiconductor data demonstrated the applicability and effectiveness of the proposed control chart. To increase the capability to detect small mean shift, we propose an exponentially weighted hybrid novelty score control chart. Simulation results indicated that exponentially weighted hybrid score charts outperformed the hybrid novelty score based control charts.

Reshaping M&A research: Strategies and tactics for a new research agenda

I apply a cognitive perspective to understand how primary cognitive mechanisms—simplification, elaboration, and interaction—have influenced the way scholars, as individuals and as a community, have queried acquisitions so far. While cognitive mechanisms have played an important role in advancing our grasp of acquisitions, they have also favored the emergence of hidden, taken-for-granted assumptions, eventually resulting in reproducing the same lines of reasoning, applying the same stock of methodological and theoretical approaches, often with a marginal contribution to our understanding of the field. To remedy this state of affairs, I propose a framework that encompasses four strategies and a set of tactics to assist scholars in challenging hidden assumptions, playing with ideas, considering context in acquisitions, and rethinking theoretical frameworks. I contrast established perspectives with novel ones to build a research agenda.

Cognitive antecedents of business models: Exploring the link between attention and business model design over time

A firm's ability to conceive performance-enhancing business models (BMs) has become a cornerstone of competitive advantage. There is consensus that external triggers spur such BM change, but the literature has remained silent on the role of internal and cognitive antecedents such as managerial attention. In our inductive case study of four corporate spin-offs, we find that top management teams (TMTs) with a specific set of attention patterns are more likely to develop performance-enhancing BM designs. However, our findings provide evidence that specific attention foci are not sufficient to enhance particular BM designs, as it is also a matter of the intensity of attention. We further find that, over time, TMTs attention patterns shift and cause changes in BM designs. The emergent theoretical framework highlights that attention is an antecedent in explaining BM designs.
