Determinants of environmental innovation—New evidence from German panel data sources 总被引:1,自引:0,他引:1
Jens Horbach 《Research Policy》2008,37(1):163-173
In most cases, empirical analyses of environmental innovations based on firm-level data relied on surveys for one point in time. These surveys allow for the inclusion of many explanatory variables such as different policy instruments or the influence of pressure groups but it is not possible to address the dynamic character of environmental innovations. This paper uses two German panel databases, the establishment panel of the Institute for Employment Research (IAB) and the Mannheim innovation panel (MIP) of the Centre for European Economic Research (ZEW), to explore the determinants of environmental innovations. The econometric estimations show that the improvement of the technological capabilities (“knowledge capital”) by R&D triggers environmental innovations. Environmental regulation, environmental management tools and general organizational changes also encourage environmental innovation, a result that has also been postulated by the famous Porter-hypothesis. 相似文献

This article discusses mechanisms, enablers and barriers for knowledge transfer in university‐industry collaboration projects involving companies, students and researchers. Data is collected through 35 qualitative interviews with Danish and Norwegian representatives from the above categories. All respondents have been involved in collaborative projects, such as student‐industry cooperation or collaboration projects between scientists and businesses. This research shows that to secure real value adding through knowledge transfer in university‐industry collaboration projects, it is important that the involved parties view each other as equal partners. It is argued that creating a better understanding of roles and competences of the involved parties can help diminish this problem. A final conclusion is that continuous knowledge sharing throughout the project seems more highly valued by the involved parties than a final report does. Best practice for collaborative projects is suggested. 相似文献

Three new combinations, one new synonym, 3 unperfectly known species and 8
distribution maps of 11 species of Chinese and Indo-Chinese Archidendron are pre-
sented in this article, as a supplement of the subject “Notes on the genera Archidendron
F. V. Mueller and Pithecellobium Martius in Mainland S. E. Asia” published in
Adansonia, ser. 2, 19(1): 3—37. 1979.
I am indebted to prof. Wu, head of Taxonomy laboratory of South China Insti-
tute of Botany for translating the article into Chinese and adding some distributivepoints of Chinese species of this genus on the maps. 相似文献

Increasing reliance on market mechanisms in higher education is analysed both as one of the approaches to steering as well as in relation to the consequences of markets for quality and accessibility of higher education. This article goes beyond the normative considerations of market elements as inherently good or bad and the economic theory-guided focus on freedoms of users and providers, by presenting an alternative conceptualization. The conceptualization adapted from studies of markets in other parts of the welfare state to the context of higher education is based on two dimensions: (1) who effectively controls production of certain goods and services and (2) how access to and funding of these goods and services are regulated. It focuses on interests of three main actors—the state, the users (students) and the providers (higher education institutions). This leads to six conceptually distinct markets, whose key characteristics are illustrated by examples from Denmark, England, India, Norway, Portugal and Serbia. The key message is that this alternative conceptualization allows identifying variance in marketization of higher education with regards to (1) which actors are empowered, (2) who are the likely winners and losers and (3) what might be the risks of introducing specific market elements in a higher education system. More generally, a more nuanced analysis relying on this conceptualization can potentially contribute to a deeper understanding of political and policy dynamics in higher education. 相似文献

Street soccer has been shown to be effective in improving cardiovascular and musculoskeletal fitness in homeless men, due to high heart rate (HR) and multiple intense actions. The purpose of this study was to investigate HR, movement pattern, rating of perceived exertion (RPE), flow and worry during street soccer for homeless women. Fifteen homeless women (30.3?±?5.0?years [± standard deviation, SD], 1.65?±?0.08?m, 65.1?±?11.0?kg, 5?±?4?years football experience) from three countries participated in 4?a-side street soccer games in Women’s Homeless World Cup 2015. Mean and peak HR were 174?±?7 and 188?±?10?beats per minute (bpm), respectively, and >160 bpm 76?±?23% of the playing time (11.1?±?2.6?min). Distance covered per minute was 68.6?±?8.9?m of which 82?±?14, 15?±?6 and 3?±?3% were covered with low- (0–9?km/h), moderate- (9–13?km/h) and high-speed (>13?km/h) running, respectively. The 43?±?5, 45?±?3 and 12?±?3% of the distance were covered running forward, sideways, and backward, respectively. Player Load was 9.2?±?1.7?arbitrary units (AU) per minute and the number of accelerations >1.5?ms–2 was 15.3?±?2.7 per minute. The score for flow was high (5.5?±?0.8), whereas rating of perceived exertion (RPE) values (4.8?±?2.5) and the score for worry (4.6?±?1.3) were moderate. Street soccer for homeless women elicits high HR and a movement pattern comparable and for some parameters even higher than street soccer and recreational football for homeless and untrained men. Street soccer may be a suitable training intervention for homeless women, and especially moderate RPE and high flow score speaks in favour of an expectation of high participation and adherence. 相似文献

IT project portfolio management (IT PPM) has evolved into a significant area of research interest, but we know little about IT PPM practices in public sector organizations. Therefore this article investigates decision-making processes in the IT PPM practices of local governments, and discusses how these practices match the normative advice proposed by the IT PPM literature. We rely on decision-making theories together with case-studies of four Danish local governments. We find that politics, intuition and coincidence play a crucial role in IT PPM decision-making, while technical rationality (as proposed by the IT PPM literature) plays a minor role. Our account also reveals how the decision-making practices create IT portfolio problems and in some aspects is considered to have a negative impact on the outcome of e-government investments. Our analysis and previous research into decision-making allows us to argue that implementing textbook-IT PPM is difficult because it relies on decision-making ideals that are incompatible with organizational contexts and individual behavior in these organizations. Instead of radically changing decision-making styles, the organizations might be better off improving IT PPM practice within the boundaries of their existing decision-making styles, and the IT PPM literature might improve support for practitioners by incorporating other decision-making styles besides technical rationality. 相似文献

This paper started life in September 2014 as a submission by the International Publishers Association (IPA) to the Office of the UN High Commissioner for Human Rights. It is the IPA’s view that human rights and intellectual property rights are not only compatible, but also mutually supportive and interdependent. Copyright in particular, is a success story. It has proven to be a powerful tool to strengthen science and culture, improve participation in them, and provide a legal framework that confers such rights and enables policies to promote them. This is particularly true in the online environment, where copyright laws enable science and culture to prosper, and are giving scientists, creators and publishers new economic ways of exercising their profession, creating the diversity of content and services that a rapidly growing majority of the world’s population is able to participate in. Copyright creates a marketplace that empowers citizens, and reduces the need for government interference with culture and science, a welcome state of affairs, in particular from the human rights perspective. 相似文献
