Do high technology acquirers become more innovative?     

Panos Desyllas  Alan Hughes 《Research Policy》2010,39(8):1105-1121

Drawing on organizational, managerial and financial theories, we explore whether acquirers become more innovative and the factors that can enhance their absorptive and financial capacity to benefit from acquisition. Over a 3-year post-acquisition window, our sample of 2624 high technology US acquisitions records early reverses followed by positive R&D-intensity changes and insignificant R&D productivity changes. Controlling for acquisition endogeneity and deal-specific effects, significant acquirer characteristic effects emerge. In related acquisitions, a large knowledge base tends to increase R&D productivity, consistent with an enhanced capacity to select and absorb targets. In unrelated acquisitions, however, this relationship becomes increasingly negative as knowledge base concentration increases, consistent with arguments for an impaired peripheral vision and core rigidities. High leverage levels raise R&D productivity gains, consistent with enhanced monitoring induced efficiency. However, high leverage growth reduces R&D-intensity, consistent with increased financial constraints and short-termism.  相似文献   

Business Informatics and the Information Systems Perspective: Implementing the IS 2010 Curriculum     

Ben Martz  Frank Braun  Jim Hughes 《Journal of Business & Finance Librarianship》2013,18(3):229-242

This article describes how the Business Informatics program at Northern Kentucky University (NKU) has evolved and, in so doing, has addressed the call from the IS 2010 Curriculum Design Committee listed below. The article initiates this discussion with a discussion of the basic systems perspective that underlies the information systems discipline. The next section presents a review of the creation of a College of Informatics (COI) at NKU that included the strategic decision of structurally moving the Information Systems Department from the College of Business. The authors then document the perceptual shift this decision created as the Information Systems Department changed its name to Business Informatics and took on the goal of expanding the discipline beyond the business domain with partnerships across campus. A short discussion on the progress made in implementing this vision is detailed. The article closes with a discussion of problems and opportunities generated.  相似文献

Self-defense and martial arts evaluation for college women: preliminary validation of perceptions of dangerous situations scale     

Hughes PP  Sherrill C  Myers B  Rowe N  Marshall D 《Research quarterly for exercise and sport》2003,74(2):153-164

Martial arts and self-defense programs train fearful people, especially women, to be more competent and confident to defend themselves in dangerous situations. However, there are no validated instruments to evaluate the effectiveness of programs purporting to teach self-protection. The Perceptions of Dangerous Situations Scale (PDSS), composed of fear, likelihood and confidence subscales, was developed and validated for university women. Participants were 368 university women, ages 17 to 45 years (M age = 20.7 years). Content validity of the PDSS was established through an expert panel, and construct validity was established through principal components analysis and determination of instructional sensitivity. Reliability was established through alpha coefficients. The PDSS, when used with university women, offers promising measurement opportunities in self-defense and martial arts settings.  相似文献

Beyond the Poststructuralist-Modern Impasse: The woman returner as 'exile' and 'nomad'     

Christina Hughes 《Gender and education》2002,14(4):411-424

This paper speaks to two articles that have been published in Gender and Education . The first, and most obvious, is that of Tett (2000). Lynn Tett's paper is concerned with an analysis of community activists 'returning' to education. I offer a complementary reading of Tett (2000) in the hope of illustrating the saliency of postcolonial perspectives for developing theorisation in the field of 'women returners'. I do this by drawing on the metaphors of 'exile' (Benhabib, 1992) and 'nomad' (Braidotti, 1994) in order to explore the issues of location and transition that form part of the material and subjective experiences of the returning woman. More immanent, however, is a conversation with Francis (1999). Becky Francis explores the relations between poststructuralism and the modernist emancipatory project of feminism. She illustrates the tensions in the binary of poststructural/modern and makes an appeal that we need to continue to worry away at the 'theoretical brick wall' (p 391) of this binary. My purpose is to contribute to Francis' appeal through the analysis that I present of the multiply located subject-in-process that is the woman returner. Specifically I argue that if we seriously wish to worry away at the binaries in academic debate we need to develop practices of critical literacy that recognise the reader as similarly multiply located and subjectively-in-process. As it is much of the contemporary literature continues to set up the reader as the humanist subject who can rationally choose, and is willing to be fixed by, some form of 'correct' intellectual position.  相似文献   

Analysis of passing sequences, shots and goals in soccer     

Hughes M  Franks I 《Journal of sports sciences》2005,23(5):509-514

Early research into how goals were scored in association football (Reep and Benjamin, 1968) may have shaped the tactics of British football. Most coaches have been affected, to a greater or lesser extent, by the tactics referred to as the "long-ball game" or "direct play", which was a tactic employed as a consequence of this research. Data from these studies, published in the late 1960s, have been reconfirmed by analyses of different FIFA World Cup tournaments by several different research groups. In the present study, the number of passes that led to goals scored in two FIFA World Cup finals were analysed. The results conform to that of previous research, but when these data were normalized with respect to the frequency of the respective lengths of passing sequences, there were more goals scored from longer passing sequences than from shorter passing sequences. Teams produced significantly more shots per possession for these longer passing sequences, but the strike ratio of goals from shots is better for "direct play" than for "possession play". Finally, an analysis of the shooting data for successful and unsuccessful teams for different lengths of passing sequences in the 1990 FIFA World Cup finals indicated that, for successful teams, longer passing sequences produced more goals per possession than shorter passing sequences. For unsuccessful teams, neither tactic had a clear advantage. It was further concluded that the original work of Reep and Benjamin (1968), although a key landmark in football analysis, led only to a partial understanding of the phenomenon that was investigated.  相似文献

A systems intervention procedure for the management of aggressive behaviour     

W.T. Floyd III  Howard Hughes 《International Journal of Disability, Development & Education》1980,27(2):99-106

A significant reduction (p < .05) in the frequency of aggressive behaviour below baseline was found with eight institutionalized mentally retarded adult males using a systems intervention procedure. Self‐charting, a token system, differential reinforcement of other behaviour, verbal and physical prompts, restraint, time out from reinforcement, seclusion, and teaching alternatives were systematically applied with staff response options being contingent on the degree of control exhibited by the subject. Although it was concluded that this is an effective treatment model, further research was suggested.  相似文献   

Advances in the application of information technology to sport performance     

Liebermann DG  Katz L  Hughes MD  Bartlett RM  McClements J  Franks IM 《Journal of sports sciences》2002,20(10):755-769

This paper overviews the diverse information technologies that are used to provide athletes with relevant feedback. Examples taken from various sports are used to illustrate selected applications of technology-based feedback. Several feedback systems are discussed, including vision, audition and proprioception. Each technology described here is based on the assumption that feedback would eventually enhance skill acquisition and sport performance and, as such, its usefulness to athletes and coaches in training is critically evaluated.  相似文献
