The concept of open innovation has gained traction among practitioners and academics. Many different aspects of open innovation have been researched, but the question of how to manage open innovation collaboration in order to achieve the desired knowledge flow across organizational boundaries remains only partly answered. Consequently, this article argues for the need to complement prior firm-centric perspectives by investigating the roles of senior management in the postmodern form of organizing that characterizes open innovation collaboration. A more in-depth understanding of managerial roles in this context can increase the chances of fruitful collaboration. Thus, the article uses an inductive, interview-based approach to explore senior management roles in two institutionalized open innovation collaborations, thereby creating an initial conceptualization of the role of managers in open innovation and forming a basis for further studies on open innovation management. In this respect, the article identifies and discusses additional managerial roles that appear to be crucial for open innovation collaborations. These roles are those of a facilitator, tactician, and sensegiver.  相似文献

Aims: To determine if EuroQoL 5-Dimension Health Questionnaire (EQ-5D) health utility scores were able to discriminate among different levels of improvement in psoriasis severity following therapy.

Materials and methods: Data were from three placebo-controlled phase 3 ixekizumab studies (UNCOVER-1, UNCOVER-2, and UNCOVER-3) with patients who had baseline Dermatology Life Quality Index scores >10 (DLQI >10). Psoriasis severity (Psoriasis Area and Severity Index [PASI]), general health utility (EQ-5D), and psoriasis-specific utility (EQ-PSO, UNCOVER-3 only) were assessed. EQ-5D-5L utility scores were generated using the England EQ-5D-5L value set, a crosswalk applied to the EQ-5D-3L United States (US) and United Kingdom (UK) value sets, and a regression-based exploratory scoring function for the EQ-PSO (UK). Analysis of variance was used to estimate change in EQ-5D-5L from baseline to Week 12 per PASI improvement level: PASI <50, PASI 50 to <75, PASI 75 to <90, PASI 90 to <100, and PASI 100. Missing data were imputed using the last observation carried forward method. Value sets for the UK, England, and the US were applied.

Results: In total, 2085 patients across UNCOVER-1, UNCOVER-2, and UNCOVER-3 had baseline DLQI >10 and available utility scores. At Week 12, mean EQ-5D utility scores increased with increasing PASI improvement levels (p?n?=?645; PASI 90 to <100: 0.141, PASI 100: 0.200; adjusted p?=?0.043).

Limitations: EQ-5D-5L index-based scores have limited ability to differentiate among psoriasis patients at the highest PASI improvement levels.

ConclusionsL Adding psoriasis-specific EQ-PSO dimensions to the EQ-5D may enhance responsiveness to improvement in skin clarity at the highest PASI levels, and, therefore, generate utility scores that better reflect treatment benefit in cost-utility models.  相似文献

A large stream of research has analyzed the effects of corporate political connections (CPCs) on firms, including first evidence on their effects on financial reporting behavior. However, the evidence so far is inconclusive, and attempts to explain the causality of effects on reporting are limited. In this article, we present the results of a systematic review of the literature on CPCs. We draw on findings in the accounting, finance, and economics literature and derive a framework that identifies four channels through which CPCs affect financial reporting. Our review of the literature suggests that effects of political connections tend to be more ambiguous than suggested by individual studies that often offer directional hypotheses. We also identify eight distinct types of political connectedness and discuss their interrelations and the proxies used in the literature to measure them.  相似文献

Existing studies of exit delay typically focus on rational, behavioral, or organizational explanations in isolation. We integrate these different theoretical explanations, develop testable hypotheses for each, and examine them using the population of US banks between 1984 and 1997. Banks' exit behavior is not consistent with theories emphasizing the option value of avoiding reentry costs. Patterns of exit do, however, support models of rational delay under ability uncertainty. Controlling for this source of rational delay, we find evidence of delay due to behavioral bias—firms discount negative signals of profitability relative to positive signals—and organizational considerations—delay increases with the separation of ownership and control. These results demonstrate that all three sets of theories are necessary to describe exit behavior. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Abstract

Progressing sustainable tourism requires both an innovative transition from “unsustainable” tourism and innovative research methods to develop theory and concepts for a sustainable tourism. While there are many ad hoc examples of initiatives, there are very few examples of firms systematically recording their medium-term evolutionary progress. This case study of an accommodation provider uses longitudinal data over 14 years, deductive and inductive methods, and comparison with other similar eco-friendly providers, to provide the first exploration of sustainability-oriented innovation by a firm attempting to make transitions. Findings show how important hindsight and insight are for continuous learning, and how broader community sustainability issues influence the owners’ worldviews. Both learning and changing views are required to support innovation. A Sustainability-oriented Service Innovation model is recommended, recognising the characteristics of a service industry where innovation can be an organic process led by humans for humans and consequently more fuzzy in its progress than the clearly defined steps that are suggested by previous research. This model seeks to assist researchers and practitioners to better measure innovative progress of service firms, and develop more relevant strategies to ease transitions towards sustainable business practices.  相似文献

This study uses meta-analytic techniques to examine the number of exposures that maximize consumer response to an ad. The results show that in an experimental setting maximum attitude is reached at approximately ten exposures, while recall increases linearly and does not level off before the eighth exposure. The findings are of interest for two opposing schools of thought in the advertising literature on effective frequency. They support the repetitionists’ beliefs over the minimalists’ beliefs on the number of ad exposures needed for maximum consumer response. The study further investigates whether the repetition effects depend on contingent factors. Low involvement and spaced exposures enhance repetition effects on attitude toward the brand. Embedded advertising and massed exposures enhance the repetition effects on recall. Repetition effects decay over time for both attitude toward the brand and recall. The study provides important implications for researchers by contributing to the discussion on effective frequency and providing support for the repetitionists’ view. This view has implications for practitioners who try to optimize advertising frequency.  相似文献

范畴帝国主义描述的是在主导性社会文化环境中形成的范畴被输出到从属性社会文化环境中的情形。洛克式的普世主义是范畴帝国主义的形而上基础,而现代化理论、理性选择理论和全球化理论则是其具体的表现。区域研究和后殖民理论都对普世主义的理论进行了反思和批评。替代普世性知识的,应当是情境性知识,这是一种源自柏克的研究取向。对情境性知识的强调意味着美国的那种将洛克强加到世界各处的绝对主义必将遭遇尴尬。  相似文献
