Resource utilization as an internal driver of alliance portfolio evolution: The Qatar Airways case (1993–2010)

This article aims to understand the role played by resource utilization levels as a driver of alliance portfolio evolution over time. Based on our theoretical framework and on a case study of Qatar Airways (199.3–2010), we develop insights into the micro-dynamics of resource structuring in firms that possess an alliance portfolio. Our research shows that firms can create either their own or network resources with different deployment modes according to their resource utilization levels to remain profitable. We also emphasize that optimized resource utilization is a key driver of resource-structuring efforts in firms. Finally, we show that based on the focal firm's life cycle phase, the level of resource utilization changes and leads to various resource-structuring mechanisms that can be observed at the alliance portfolio level.     

青春之歌——国产青春剧的类型演进与文化逻辑

作为中国电视剧的流行创作类型,国产青春剧的类型演进始终与中国社会文化语境的斗转星移相呼应。近几年,随着媒介融合和“互联网+”战略的推进,国产青春剧在快速发展态势中呈现出较之前更为复杂的青春文化样貌。这不仅意味着国产青春剧类型边界的不断扩充与升级,而且反映出青年文化在电视剧话语建构中的策略性表达模式。通过对近三十年来国产青春剧发展状况的分析,指出在不同的社会历史语境中,其类型发展经历了“移植”“自生”以及“复合”发展的过程,详细分析这种类型演进背后的文化逻辑和对青春世界的想象图景,讨论其中折射出的中国社会文化和价值观念的转型发展,力图为当下国产青春剧的发展提供历史经验的借鉴。     

Differential evolutionary algorithm in the construction process of optimal experimental designs

This article shows how a differential evolution algorithm can be used to find statistical designs under several optimality criteria as A, D, and T. The general algorithm of differential evolution is described and then applied on constructing optimal designs for several well-known models and compare them with those already available by other algorithms, in terms of relative efficiency. Moreover, the great effect of population size in the running of this algorithm establishes a precedent in the use of differential evolution algorithms over genetic algorithms.

Developing management capability within a horizontal supply chain in performance measurement deployment and evolution: a Dynamic Capabilities and Goal Theory perspective

Abstract

Complex collaboration in rapidly changing business environments create challenges for management capability in Utility Horizontal Supply Chains (UHSCs) involving the deploying and evolving of performance measures. The aim of the study is twofold. First, there is a need to explore how management capability can be developed and used to deploy and evolve Performance Measurement (PM), both across a UHSC and within its constituent organisations, drawing upon a theoretical nexus of Dynamic Capability (DC) theory and complementary Goal Theory. Second, to make a contribution to knowledge by empirically building theory using these constructs to show the management motivations and behaviours within PM-based DCs. The methodology uses an interpretive theory building, multiple case-based approach (n = 3) as part of a USHC. The data collection methods include, interviews (n = 54), focus groups (n = 10), document analysis and participant observation (reflective learning logs) over a five-year period giving longitudinal data. The empirical findings lead to the development of a conceptual framework showing that management capabilities in driving PM deployment and evolution can be represented as multilevel renewal and incremental Dynamic Capabilities, which can be further understood in terms of motivation and behaviour by Goal-Theoretic constructs. In addition, three interrelated cross-cutting themes of management capabilities in consensus building, goal setting and resource change were identified. These management capabilities require carefully planned development and nurturing within the UHSC.     

Principal weighted logistic regression for sufficient dimension reduction in binary classification

Sufficient dimension reduction (SDR) is a popular supervised machine learning technique that reduces the predictor dimension and facilitates subsequent data analysis in practice. In this article, we propose principal weighted logistic regression (PWLR), an efficient SDR method in binary classification where inverse-regression-based SDR methods often suffer. We first develop linear PWLR for linear SDR and study its asymptotic properties. We then extend it to nonlinear SDR and propose the kernel PWLR. Evaluations with both simulated and real data show the promising performance of the PWLR for SDR in binary classification.     

俗语与骈文--刘师培的进化文学观

文学进化观在近代文学观念中很值得研究,从梁启超和刘师培都可见这种文学观念的影响。而刘师培的进化文学观尤其复杂。本文从他立论的基础即俗语和骈文,从语言文字和文体变迁两个角度来讨论这个问题,认为他的进化文学观只是一种论证的策略,承认俗语和为骈文立正统分别合于他的启瀹齐民和保存国学两个立场。刘师培只是从不同的立场和不同的角度来使用他的进化文学观,以至于他的进化文学观不成系统,但是它却暗合了文学发展的潮流。
