Although research on open collaboration for innovation has generally focused on the voluntary participation of individuals who are not strictly governed by formal authority concentrated at higher levels of organizational hierarchy, more recent studies highlight the importance of exploring how their tasks should be organized to enhance performance outcomes. This study extends this line of work by conceptualizing polyarchy as a decentralized decision-making structure that directs how core members of a project team screen a large collection of novel ideas generated by team members, and empirically examining whether and how polyarchy affects task completion time. In the context of online projects for open-source software development at GitHub, we find that a polyarchical decision-making structure reduces task completion time. Closer examination also shows that this positive effect on decision-making speed becomes stronger when tasks are explorative rather than exploitative in nature. Implications for open, distributed models of innovation and nontraditional forms of decision-making structures are discussed. [ABSTRACT FROM AUTHOR]

The article discusses the concept of digital twins and their applications in Industry 4.0. Digital twin technology has become more advanced and widespread, driving the development of Industry 4.0. It is used in various sectors such as product design, predictive maintenance, and virtual reality applications. The article highlights different articles in a special issue that explore the potential applications of digital twins in sectors like construction, education, energy, manufacturing, and maritime. The article concludes by discussing the future research directions and challenges in implementing digital twin technology. [Extracted from the article]

Building on the literature on resource reconfiguration theory, we formulate a new theoretical framework that explains how executive redeployment within a diversified firm transfers different types of human capital embodied in executives to different units facing specific business challenges. In the empirical context of Korean business groups, we find that executives with unit-specific human capital, like turnaround experience, competitive experience, and international expansion experience, are redeployed to units with corresponding business challenges like financial difficulties, intensifying competition, and early-stage international expansion, respectively. We also show that executives with unit-generic human capital, like corporate management practices and interunit coordination experiences, are redeployed to younger units seeking to establish corporate-level policies and practices. Additional analyses also show that the value of firm-specific human capital in driving the redeployment of executives is contingent on their functional orientation and seniority. Funding: S.-J.

Although studies underscore the importance of creating a coherent collective identity in order to legitimate a new market category, strategy and entrepreneurship research is divided on whether and to what degree an entrepreneur will engage in collective action to promote the identity. To reconcile the inconsistency, we introduce the concept of entrepreneurial shared fate—the belief of a focal venture that it and its competitors are bound together by a sense of belongingness and equally experience similar consequences—and explore how external threats can influence the degree of shared fate. We conceptually distinguish between communal and individual threats and propose that communal threats will increase, whereas individual threats will decrease, shared fate. We also explore boundary conditions that strengthen and weaken the main effects of perceived communal and individual threats on collective identity promotion. Empirically, we examine venture identity framing in response to forest-conservation activism in the U.S. wood pellet market. Implications for research on new market categories, collective identity, optimal distinctiveness, and forest management are discussed. [ABSTRACT FROM AUTHOR]

Why do scientists withhold information from colleagues, violating the professional norm of sharing? Norm violations are usually attributed to individual interests that lead scientists to reject professional norms. In contrast, [...]

A common strategy used by professions to support claims of workplace jurisdiction involves the institutionalization of professionally endorsed formal structures, yet both theory and research suggest that ensuring the implementation of such structures after formal adoption can be problematic. This study investigates the influence of organizational characteristics on the implementation of one professionally created institution in higher education organizations, tenure systems for faculty employment. Our results suggest that implementation of tenure systems is negatively affected by internal resource pressures but positively affected by countervailing pressures from professionally linked constituents. The results also suggest self-limiting aspects of the use of tenure systems. [ABSTRACT FROM AUTHOR]

Digital pathology incorporates the acquisition, management, sharing, and interpretation of pathological information, including slides and data, in a digital environment. Digital slides are created using a scanning device to capture a high-resolution image on glass slides for analysis on a computer or a mobile device. Though digital pathology has drastically grown over the last 10 years and has created opportunities to support specialists, few have attempted to address its full-scale implementation in routine clinical practice. To incorporate new technologies in diagnostic processes, it is necessary to study their application, the value they provide to specialists, and their effects on improvements across the entire workflow, rather than studying a particular element. In this study, we aimed to identify what have the current digital pathology systems contributed to the pathological and diagnostic process. We retrieved articles published between 2010 and 2020 from the databases PubMed and Google Scholar. We explored how digital pathology systems can better utilize existing medical data and new technologies within the current diagnostic workflow. While the evidence concerning the efficacy and effectiveness of digital pathology is mounting, high-quality evidence regarding its impact on resource allocation and value for diagnosis is still needed to support clinical diagnosis and policy decision-making., Competing Interests: CONFLICT OF INTEREST No potential conflict of interest relevant to this article was reported., (Copyright © 2021 Korean Society of Exercise Rehabilitation.)
