Impacts of Globalization on E-Commerce Use and Firm Performance: A Cross-Country Investigation     

Kenneth L. Kraemer  Jennifer Gibbs  Jason Dedrick 《The Information Society》2005,21(5):323-340

This article develops and tests a model examining the relationship between firm globalization, scope of e-commerce use, and firm performance, using data from a large-scale cross-country survey of firms from three industries. We find that globalization leads to both greater scope of e-commerce use and improved performance, measured as efficiency, coordination, and market impacts. Scope of e-commerce use also leads to greater firm performance of all three types. Globalization has differential effects on B2B and B2C e-commerce, however, such that highly global firms are more likely to do B2B but less likely to do B2C. Our findings provide support for Porter's (1986) thesis that upstream business activities (namely, B2B) are more global while downstream business activities (B2C) are more local or multidomestic.  相似文献   

Digital redesign tracker for cascaded analog systems with state saturation and external loads     

Jason Sheng-Hong Tsai  Meng-Che Wu  Leang-San Shieh 《Journal of The Franklin Institute》2005,342(7):852-876

This paper presents a newly developed digital redesign control scheme with a weighted switching strategy and output-reference tracking, for a cascaded analog system with state saturation and external loads. The proposed method improves the generally poor transition response and output deviation caused by state-saturation constraint and external loads. It replaces an existing or theoretically well-designed analog controller with state saturation, by a digital controller with almost identical performance.  相似文献

The expanding role of university patenting in the life sciences: assessing the importance of experience and connectivity     

Jason Owen-Smith 《Research Policy》2003,32(9):1695-1711

We extend debates about the sources of university capabilities at research commercialization. Drawing upon quantitative data for a panel of 89 research-intensive US universities and interview data from two academic licensing offices, we model the relationship between technology transfer experience, embeddedness in biotechnology industry networks, basic science quality and capacity, and citation impact measures of university life science patents. Technology licensing officers draw upon the expertise of corporate partners to evaluate the potential impact of invention disclosures. The information gleaned through network ties to industry enables well-connected institutions to develop higher impact patent portfolios. Reaping the benefits of such connections, however, requires experience in balancing academic and corporate priorities to avoid the danger of ‘capture’ by industrial interests as overly tight connections limit patent impact. This pattern of diminishing returns to connectivity is robust across multiple citation measures of patent quality.  相似文献   

Static and dynamic behavior of concrete slabs reinforced with chemically reactive enamel-coated steel bars and fibers     

Dong-ming Yan  Shi-kun Chen  Gen-da Chen  Jason Baird 《浙江大学学报(A卷英文版)》2016,17(5):366-377

In this study, the effect of steel fibers coated with chemically reactive enamel (CRE) on the system response of concrete structures with reinforcing bars has been investigated for the first time. In particular, the ultimate strength, ductility, and failure mechanism of 24 reinforced concrete slabs were experimentally characterized under static and blast loads. CRE coating applied on steel bars reduced the crater area of slabs under blast loads by up to 20%; it slightly increased the strength of slabs and significantly reduced the strength degradation of slabs when increasingly deflected under static loads, making the slabs more ductile. CRE coating applied on steel fibers increased the strength of slabs by up to 16% under static loads. The influence of CRE coating applied on both steel fibers and bars may be taken into account by introducing a coating factor in the range of 0.57<β<1.0 in the American Concrete Institute (ACI) development length equation.  相似文献

Attitudes toward the level of men's involvement in abortion decisions     

Nelson ES  Coleman PK  Swager MJ 《The Journal of humanistic education and development》1997,35(4):217-224

College students completed a questionnaire that assessed their attitudes toward the level of male responsibility in abortion decisions. Overall, both men and women thought that men should have some degree of involvement in the abortion decision. However, as expected by the first hypothesis, men indicated a desire for more responsibility in the abortion decision than women thought the men should have. A second hypothesis predicted women would feel more strongly than men that abortion was strictly a woman's issue. Contrary to the hypothesis, women tended to disagree that abortion was strictly a women's issue. Implications of the findings are discussed.  相似文献
