The U.S. military argues that homosexuals are unfit for service because their presence compromises military readiness and
unit cohesion. Based on this assumption, it continues to discharge homosexuals at an average rate of approximately 925 per
year. On the other hand, the extant research suggests that homosexuals are no more disruptive to military life than their
heterosexual counterparts. By integrating the legal and scientific literature, this paper examines the soundness of the military’s
assumptions and aims to improve our understanding of the issues involved. Within this context, the efficacy of the military’s
“Don’t Ask, Don’t Tell, Don’t Pursue” policy and whether it is in the best interest of the military and its soldiers and sailors
is discussed.

Life science innovation has led to significant improvements in clinical outcomes and has been a source of financial growth for individuals and institutions capable of performing appropriate investments in this sector. Several groups have developed methodologies to assist medical technology innovators in the design and development activities. Unfortunately, these tools have not aided the general investment community to profit from these enterprises. This situation has contributed to a general reduction in risk capital directed towards life sciences compared to other industries. We review the current investment practices in the life science sector and present a comprehensive stage-gate model that aims to captures this investment process. An analysis of best practices and in-depth interviews with 68 life sciences investors and entrepreneurs worldwide are used to support such model. A single case-control study comparing life science investment execution within two similar investment firms was conducted to evaluate feasibility in the implementation of these practices. The stage-gate model includes (I) General vision and investment strategy definition; (II) Venture search, screening and rapid pre-evaluation; (III) Due diligence and negotiation of terms; (IV) Portfolio management, evaluation, and exit. The difference in execution of investment and results from a post-performance Root Cause Analysis were consistent with a reduction in perceived risk from the case company trained with the proposed model compared to the control. This suggests that our developed model and process may be useful in encouraging life sciences investment via evidence-based evaluations. 相似文献

A Socio‐Psychological Perspective on Team Ambidexterity: The Contingency Role of Supportive Leadership Behaviours 下载免费PDF全文
Justin J. P. Jansen Konstantinos C. Kostopoulos Oli R. Mihalache Alexandros Papalexandris 《Journal of Management Studies》2016,53(6):939-965
In addressing the notion of team ambidexterity, we propose that socio‐psychological factors (i.e., team cohesion and team efficacy) may help team members to resolve paradoxical challenges and to combine exploratory and exploitative learning efforts. In addition, we theorize that senior executives may play an important role in facilitating the emergence of ambidexterity at lower hierarchical levels. In doing so, we develop a multilevel contingency framework and propose that the effectiveness of teams to achieve ambidexterity is contingent upon supportive leadership behaviours at the organizational‐level. Using multilevel, multisource, and temporally separated data on 87 teams within 37 high‐tech and pharmaceutical firms, we not only reveal how team cohesion and efficacy may matter for the emergence of team ambidexterity but also show that the effectiveness of supportive leadership behaviours from senior executives varies across cohesive and efficacious teams. 相似文献

Do ongoing networks block out new friends? Reconciling the embeddedness constraint dilemma on new alliance partner addition 下载免费PDF全文
Research Summary: This study addresses a theoretical dilemma regarding how alliance network constraint (reflected by network cohesion) affects a firm’s alliance formation with new partners. Using a network pluralism approach, we separate a firm’s ego alliance network into two activity‐based networks—an exploratory network and an exploitative network—based on the primary value chain activity involved in each alliance. We argue that the cohesion of exploratory or exploitative networks has an inverted U‐shaped effect on the addition of new partners in the same activity‐based network, and a positive effect on the addition of new partners in the other network. Results based on data from the biotechnology industry largely support our predictions with one exception. Our study contributes to both scholarly understanding of network embeddedness and alliance practice. Managerial Summary: The structure of firms’ ongoing alliance networks may have paradoxical implications for their efforts to search for and form alliance with new partners. That is, when a firm’s alliance partners are tightly connected with each other, the cohesive network tends to both encourage and impede the focal firm to add new partners. We resolve this dilemma by showing that when a firm is deeply entrenched in a cohesive alliance network conducting a certain type of activities (e.g., R&D activities), it may not easily add new R&D alliance partners. However, it may still be able to escape from the cohesive R&D alliance network by seeking new partners conducting other activities (e.g., manufacturing activities). 相似文献

This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the article provides theoretical argumentation for emergence of a new innovation paradigm, driven by the rise of the entrepreneurial ecosystem, its incorporation into S3, and a consequent retreat of science policy in favor of entrepreneurial policy. The empirical analysis is focused on the funding trends seen in the business and public research sectors over the last decade (2008–2017), which have clearly shown that S3 has not contributed, despite expectations, to an increase in public expenditure for science. This signifies S3's neglect of public research within entrepreneurial ecosystems and challenges the ability of S3 to reduce wide disparities in research and innovation performance across the European Union. This ultimately endangers the innovation potential of the entrepreneurial ecosystem itself. 相似文献

It has been argued that ‘dirty work’ is characterised by strong occupational and workgroup cultures. This literature has mainly focused on direct workers, but this article largely attends to indirect ‘dirty’ workers, specifically meat inspectors, through ethnographic research conducted in a UK slaughterhouse. Four arguments are developed; the first is that ‘dirty workers’ may not all display group cohesiveness; indeed, individualisation may be more evident depending upon the technology used, internationalisation and employment conditions. Second, there is complexity and diversity within ‘dirty work’ and even single occupations can contain considerable variety, rendering generalisations problematic. Third, we argue that much greater attention needs to be given to the wider contextual issues affecting ‘dirty work’, specifically changing labour markets, itinerant labour, economic conditions and technologies. Finally, we argue that stigmatised work may become more so if it is equated with the low wage economy and/or undercutting conditions of employment through exploiting migrant labour. 相似文献
