Horizontal collaborations emerged as a new strategic option in the logistics sector during the last decade. However, successful implementation of horizontal collaborations is far from a developed issue due to several barriers that exist or emerge when setting up such collaborative projects. This study aims at identifying the enabling factors supporting successful implementation of horizontal collaborations in the logistics sector, and in identifying key success factors that logistics service providers (LSPs) should consider. Results from a within‐ and cross‐case analysis of two horizontal collaboration projects in the contract logistics sector support the proposed theoretical framework, highlighting both enabling and key success factors of horizontal collaborations. The former refers to factors that are related to LSPs, customers, and industries, whereas the latter results in a triple‐win scenario characterised by LSP competences, trust, and environmental management orientation of successful horizontal collaboration projects.  相似文献

《公司法》将直索责任的性质界定为连带责任,但对其为何种连带责任却不甚明确。法院裁判各执一词,学界亦对此争论不休,形成直索责任性质迷局。迷局的根源在于我国早期公司法实践中系列法律文件对各种责任性质混用所造成的思维定式以及我国对民事责任的长期误读所带来的概念混淆。对直索责任制度的本源分析及对其滥觞之地美国的理论界与实务界关于直索责任性质态度的梳理后发现,直索责任作为一种利益平衡机制,并无限度,也无先后顺序,应当为共同连带责任。  相似文献

In this paper we propose a model to analyse the motivation of academic entrepreneurs that comprises six dimensions: personal, relating to the entrepreneurial opportunity, to scientific knowledge, to the availability of resources, to the incubator organization, and to the social environment. The model is tested based on information from a survey administered to 152 Spanish academic entrepreneurs. Our results show that entrepreneurial opportunity is not part of the entrepreneurial motivation, but is of the utmost importance to academic entrepreneurs. Also, we find the scientific knowledge is the main driver of entrepreneurial activity in the academia.  相似文献

This paper studies empirically the relationship between the sources of knowledge, innovation and productivity in Knowledge Intensive Business Services using French micro data and sheds some new light on the production of knowledge and on effects of innovative output on firm productivity. Both an innovation function and a production function augmented with dummy endogenous innovation are estimated. Three estimators which control for endogeneity of the dummy innovation are employed: the first is a maximum likelihood estimator of the equations’ system while the other two are built in the instrumental variables framework. These estimators give useful complementary information because of the usual efficiency-robustness tradeoff comparing system-equations and single-equation estimators. We find that innovation is frequent in Knowledge Intensive Business Services and has a strong and positive effect on productivity. As in manufacturing, the main determinant of innovation is formal knowledge resulting from R&D or from acquisitions of equipment, patents or licenses.  相似文献

Research on work–life balance (WLB) practices has increased in recent years. Academics affirm that the implementation of WLB practices helps to achieve better organizational results and improve employee outcomes such as higher satisfaction and commitment, and reduce turnover intentions. However, some authors have argued that there are differences between the availability of WLB practices in companies and employees' perceptions of access to such practices. The literature on the differences in perceptions between managers and employees in relation to WLB and its effects is sparse. Using two samples of 229 managers and 511 employees from the same firms, we in this paper contribute to our knowledge of the existence of the perception gaps between managers and employees and their influence on the take-up of WLB. Implications for academics and practitioners are discussed.  相似文献

The buffering effects of supervisor support on the stressor–strain relationship have proven elusive in prior research (Beehr, Farmer, Glazer, Gudanowski and Nair (2003), ‘The Enigma of Social Support and Occupational Stress: Source Congruence and Gender Role Effects,’ Journal of Occupational and Health Psychology, 8, 220–231). We built on emerging work on source congruence and conservation of resource theory to test a series of hypotheses intended to clarify these mixed findings. Using a sample of 768 employees from 45 organizations in North America, results from moderated regression analyses, showed that the effects of supervisor support on the stressor–strain relationship depended on source congruence. In accordance with our predictions, although we found buffering effects for the physical stressors–strain relationship, we found a reverse buffering effect for the role conflict–strain relationship. These differential buffering effects did not emerge when considering coworker support. We discuss the implications of our results for shedding light on the mixed evidence regarding buffering work stressors reported in prior research.  相似文献

A new framework is presented for the study of the existence and uniqueness of solutions to the Koopmans’ equation in the unbounded case, that is based on the contraction mapping approach. In the bounded below case with bounded consumption streams, uniqueness of the solution in the whole class of weak-star continuous utility functions is obtained. When the aggregator is unbounded below and/or consumption streams are unbounded, existence of a weak-star continuous solution is shown, and a simple criterium to check the sufficient conditions for existence is provided.
