This paper reviews 726 academic research studies covering logistics and supply chain management (L'SCM) applications within a global context. Articles are analyzed according to their publication year and outlet, common themes, and countries or regions investigated. The sample was drawn from the ABI/INFORM Global database, which includes almost 1,800 journal titles. The review offers a starting point for researchers, graduate students, faculty members or practitioners examining international L'SCM applications. The article also draws attention to the wide array of global L'SCM studies conducted, their settings and viewpoints. Additionally, this paper highlights some of the most interesting works and draws attention to lesser‐researched countries and regions of the world. The overview also provides an introduction for practitioners and managers to what academic research has covered in the area of global L'SCM. Practitioners can use this review as a starting point for the identification of relevant and useful references for their particular task. 相似文献

Enterprise social media (ESM) have become increasingly widespread, but many intranet communities barely survive, miss their initially planned targets, or are even terminated. Research on technology acceptance can be a useful approach to improve adoption rates, but more empirical research needs to be conducted to examine factors driving the adoption of enterprise social media. To address this gap, we develop a model of individual ESM adoption, including technological and individual factors based on findings from collaboration and knowledge-sharing research. Because different ESM tools, such as blogs, social networks, and wikis, can be employed for fundamentally different uses, we explain differences between individual adoptions of the three technologies by identifying their uses and gratifications from the perspective of employees. The model is tested in three parallel studies, one for blogs, social networks, and wikis each, among employees of an international technology company in the pre-implementation phase. We find substantial differences between the factors influencing the intention to adopt the three applications. This provides the basis to employ the applications in a more effective way by considering organizational and employee needs. 相似文献

The paper refers to legal questions that arise in connection with the collection and use of genetic data in the context of private insurance. The content and meaning of § 18 GenDG is described. Then, § 18 GenDG is set in relation to notification requirements out of the VVG. The paper exemplarily emphasizes that, despite the codification of GenDG, specific legal problems arise. Accordingly, the paper provides solutions to overcome these problems. Particular problems refer to the role of genetic data of third parties and according relations to the family history, possibilities to communicate genetic data by the insured in case of medical indication, the ratio of predictive and diagnostic genetic testing and the range of the total limits of § 18 I 2 GenDG. 相似文献

While considerable progress has been made in understanding land use change, land system science continues to face a number of grand challenges. This paper discusses these challenges with a focus on empirical land system studies, land system modelling and the analysis of future visions of land system change. Contemporary landscapes are contingent outcomes of past and present patterns, processes and decisions. Thus, empirical analysis of past and present land-use change has an important role in providing insights into the socio-economic and ecological processes that shape land use transitions. This is especially important with respect to gradual versus rapid land system dynamics and in understanding changes in land use intensity. Combining the strengths of empirical analysis with multi-scale modelling will lead to new insights into the processes driving land system change. New modelling methods that combine complex systems thinking at a local level with macro-level economic analysis of the land system would reconcile the multi-scale dynamics currently encapsulated in bottom-up and top-down modelling approaches. Developments in land use futures analysis could focus on integrating explorative scenarios that reflect possible outcomes with normative visions that identify desired outcomes. Such an approach would benefit from the broad and in-depth involvement of stakeholders in order to link scientific findings to political and societal decision-making culminating in a set of key choices and consequences. Land system models have an important role in supporting future land use policy, but model outputs require scientific interpretation rather than being presented as predictions. The future of land system science is strongly dependent on the research community's capacity to bring together the elements of research discussed in the paper, via empirical data collection and analysis of observed processes, computer simulation across scale levels and futures analysis of alternative, normative visions through stakeholder engagement. 相似文献

This study examines the merger premiums paid for a sample of 320 bank acquisitions consummated during the period January 1982 through October 1990. The results of the research indicate that higher merger premiums were paid for, (a) smaller size targets, (b) targets with higher return on common equity ratios (pre-merger), (c) targets with higher leverage as measured by the percentage of primary capital to total capital, (d) targets in a different state than the bidder, and (e) transactions carried out through exchange of stock as opposed to a cash purchase. 相似文献

An Analysis of Covariance Risk and Pricing Anomalies 总被引:2,自引:0,他引:2
This article examines the link between several well-known assetpricing "anomalies" and the covariance structure of returns.I find size, book-to-market, and momentum strategies exhibita strong, weak, and negligible relation to covariance risk,respectively. A size factor helps predict future volatilityand covariation, improving the efficiency of investment strategies.Moreover, its premium rises following increases in both itsvolatility and covariation with other assets. These effectsare amplified in recessions. No such relations exist for book-to-marketor momentum. These findings may shed light on explanations forthese premia and present a challenging set of facts for futuretheory. 相似文献

Asset-Liability Management has gained increased significance within the German insurance industry. This was mainly driven by recent capital market developments. In fact, insurers have encountered challenges to earn given interest guarantees. Regulatory changes also require more sophisticated ALM-tools. Solvency II will change the underlying paradigm and shift balance sheets perception towards a market value oriented view. Especially liabilities will have to be accounted for using the fair value approach. Most ALM-tools appear to be unable to cope with these demands. To improve this current practice, in this paper a Markowitz-approach is employed in order to generate an integrated method for the optimization of assets and liabilities in the life insurance industry. This technique aims to link new regulatory requirements to the latest capital market theory and therefore delivers a procedure for an integrated asset allocation policy in the insurance industry. 相似文献
