The main objective of this study is to investigate the impact of corporate research and development (R&D) activities on firm
performance, measured by labour productivity. To this end, the stochastic frontier technique is used on a unique unbalanced
longitudinal dataset comprising top European R&D investors over the period 2000–2005. In this framework, this study quantifies
technical inefficiency of individual firms. From a policy perspective, the results of this study suggest that if the aim is
to leverage firms’ productivity, the emphasis should be put on supporting corporate R&D in high-tech sectors and, to some
extent, in medium-tech sectors. On the other hand, corporate R&D in the low-tech sector is found to have a minor effect in
explaining productivity. Instead, encouraging investment in fixed assets appears important for the productivity of low-tech
industries. Hence, the allocation of support for corporate R&D seems to be as important as its overall increase and an ‘erga omnes’ approach across all sectors appears inappropriate. However, with regard to technical efficiency, R&D intensity is found
to be a pivotal factor in explaining firm efficiency and this turns out to be true for all industries. 相似文献

Diagnostic theories are fundamental to Information Systems practice and are represented in trees. One way of creating diagnostic trees is by employing independent experts to construct such trees and compare them. However, good measures of similarity to compare diagnostic trees have not been identified. This paper presents an analysis of the suitability of various measures of association to determine the similarity of two diagnostic trees using bootstrap simulations. We find that three measures of association, Goodman and Kruskal’s Lambda, Cohen’s Kappa, and Goodman and Kruskal’s Gamma (J Am Stat Assoc 49(268):732–764, 1954) each behave differently depending on what is inconsistent between the two trees thus providing both measures for assessing alignment between two trees developed by independent experts as well as identifying the causes of the differences. 相似文献

Changes in diet and nutrition, along with other lifestyle changes during the last decades, have affected the nutrition-related disease profile in many developing countries. This phenomenon, or process, is known as ‘The Nutrition Transition’. Several studies on adolescents in South Africa have shown that overweight and obesity are increasing, possibly due to this process. The aim of the present study was to extend our knowledge on the nutrition transition and the factors that influence adolescents’ choice of food in South Africa, and to develop policy recommendations that could facilitate the adolescents’ right to adequate food as laid down in the South African Constitutional Bill of Rights. The data were collected through focus groups with 25 female learners (grade 10, 14–16 years) from urban public schools in Cape Town and key informant interviews with 10 school staff members. The most important nutritional concerns that emerged from the analyses, included skipping breakfast and the consumption of unhealthy tuck shop food. In terms of the human right to adequate food, these findings reflected lack of availability and access to adequate food within the household, at schools, and in the community. In addition, the study showed that there were no or few opportunities for physical activity for adolescents during and after school hours. Social factors, including social norms and a need to conform to peer group pressure, appeared to affect the behaviour of learners considerably. Traditional foods appeared to have lost their importance, while learners preferred to consume fast foods and to adopt a more westernised diet connected to affluence and social acceptance. Traditional and more “Western” body perceptions co-existed among the study participants. The nutrition transition in South Africa is of a complex nature because of large differences that exist amongst different ethnic and socioeconomic groups. Policy decisions should be based on an understanding of these diverse factors. The media and the food industry should be encouraged to work with government in influencing adolescents to make healthy food choices. Cultural perceptions which may lead to unhealthy choices and lifestyle need to be addressed while at the same time respecting people’s cultural pride and human dignity. It is recommended that human rights principles are used purposively in the future in policy formulations, interventions, evaluation and monitoring. 相似文献

ABSTRACTThis article argues that the nonprofit case for corporate volunteering is complex, requiring a multi-level perspective on the outcomes for nonprofit organizations (NPOs). To develop this perspective, we adopted an inductive research approach, conducting 39 exploratory semi-structured interviews with NPO staff. We argue that NPO scholars and practitioners should disentangle individual and organizational-level outcomes resulting from interactions between corporate volunteers and NPO staff, as such micro-dynamics ultimately affect NPO services. Moreover, these outcomes are subject to conditions at the organizational level (e.g. involvement of intermediaries), as well as at the individual level (e.g. type of assignment). Our study highlights the complexity that should be considered when addressing the fundamental question of whether corporate volunteering contributes to the ability of NPOs to provide their services, and under what conditions. We therefore propose that corporate volunteer management within NPOs is inherently, albeit contingently, intertwined with the services that these organizations provide. 相似文献
