Over 90 percent of companies are estimated to use IT Service Management (ITSM) frameworks, yet there is little research on
their benefits to the Information Technology (IT) department and the business units. An international survey of 491 firms
was conducted to assess the benefits of the IT Infrastructure Library (ITIL), the de-facto ITSM framework, specifically on
how these benefits evolve as companies increase their adoption of the ITIL model. Also studied are the perception of challenges
of the implementation and the number of ITIL processes implemented in relation to the progress of the adoption of ITIL. Results
indicate that as the maturity of implementation increases, the perception of challenges decreases. Findings also show that
as the maturity of implementation increases, the number of realized benefits increases, as well as the number of implemented
ITIL processes. Implications for practitioners and researchers are also discussed. 相似文献

This study addresses the trade‐off between nutrition and taste in expenditure on breakfast cereal, milk, bread, and soft drinks. Within each category, products have similar cost and convenience, but have markedly different flavor and nutritional content. Using annual expenditure data for a large sample of households participating in the ACNielsen Homescan system, we regress a measure of “healthiness” on household demographics and market prices, and find that households with college‐educated heads and higher incomes made significantly healthier choices in all four categories. These effects are puzzling in that the nutritional differences between products were well known to consumers, and there are no cost or convenience differences between them. The presence of children was associated with less healthy choices, especially for cereal and bread, while older households made healthier choices in all categories except milk. 相似文献

Methods and tools for integrated assessment of land use policies on sustainable development in developing countries 总被引:4,自引:0,他引:4

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem. 相似文献

European countries need to expand employment among older individuals. Many papers have examined this issue from different
angles. However, very few seem to have considered its gender dimension properly, despite evidence that lifting the overall
senior employment rate requires significantly raising that of women older than 50. The key issue examined by this paper is
whether employers are willing to employ more older workers, in particular older women. The answer depends to a large extent
on the ratio of older individuals’ productivity to their cost to employers. To address this question we tap into a unique
firm-level panel of Belgian data to produce robust evidence on the causal effect of age/gender on productivity and labour
costs. We take advantage of the panel structure to identify age/gender-related differences from within-firm variation. Moreover,
inspired by recent developments in the production function estimation literature, we address the problem of endogeneity of
the age/gender mix, using a structural production function estimator (Olley and Pakes in Econometrica 64(6):1263–1297, 1996; Levinsohn and Petrin in Rev Econ Stud 70(2):317–341, 2003) alongside IV-GMM methods where lagged value of labour inputs are used as instruments. Our results indicate a small negative
impact of larger shares of older men on the productivity-labour cost ratio. An increment of 10%-points of in their share causes
a 0.17–0.69%-point contraction. However, the main result is that the equivalent handicap with older women is larger, ranging
from 1.3 to 2.0%-points. This is not good news for older women’s employability. And the vast services industry does not seem
to offer working conditions that mitigate older women’s disadvantage, on the contrary. 相似文献

In this paper we present a framework for analyzing changes in strategic performance. Traditional measures for comparing the strategic performance across firms or over time have been return on investment (ROI) and its component ratio, return on sales (ROS). We decompose the ROS ratio into four separate ratios that capture the impact of changes in a firm's productivity, price recovery, product mix and capacity utilization on its profitability. These ratios help to highlight the micro sources of strategic success or failure. They can be used to assess changes in the performance of a firm compared to itself over time, or to other firms in its industry group. This framework can also be used to evaluate changes in the dynamic performance of an industry as a whole. We illustrate the use of these ratios with a 4-year analysis of the performance of a large manufacturing company. We also demonstrate how the technique can be applied to an industry with an evaluation of the performance of U.S. telecommunications firms between 1975 and 1987, a period during which the industry experienced a progressive increase in competitive pressure. 相似文献
