The purpose of this study is to investigate the relationship between product innovativeness and groups of outcomes flowing from the computer software product development process and the associated knowledge acquisition process. Data from interviews of managers in 94 software projects are analysed, and three groups of outcomes are measured: project performance, knowledge enhancement, and the strengthening of linkages to external actors/sources. The high innovative products show higher project performance for all measures of project performance compared with low innovative products. Similar results were found for all measures of personnel knowledge enhancement outcomes. Changes in the importance of linkages to nine different external sources of knowledge used by the firms during the knowledge acquisition process, also show some positive outcomes with respect to rising innovativeness levels. Strengthening of external linkages is found for 66% of the investigated linkages between one or two innovativeness levels. Of these, the linkages to hardware manufacturers, co-operation partners, and universities and other research institutions show strengthening when high innovativeness products are compared with low-level products. As the project performance and knowledge enhancement outcomes are due, in part, to knowledge gained within linkages to external actors/sources, managers could consider whether giving special attention to managing these linkages would be a winning innovation strategy for their particular firm. 相似文献

Using two large samples for 1988 and 1995 we decompose the Gini coefficient of household income according to type of income with the purpose of analyzing reasons for the rapid increase of inequality. The results show that the change in relative size of money income and its changed profile are found to be the major processes behind the rapid increase of income inequality in rural China. Changes in housing allocation and an increased number of retirees in combination with higher benefits have made inequality increase in urban China and in China as a whole.

Borda's vote method was used by the French Academy from 1796 to 1803 when Napoleon got it abolished. In the laws and regulations
of the Academy there are stipulations regarding the election of new members. The practice is demonstrated by some examples
from the protocols.
In fact, Borda presented two vote methods which he showed would give the same conclusion. The method which has not been in
the limelight proves to be the same one as is used for selecting the best player in chess tournaments. 相似文献

It is a known phenomenon that it is difficult to make organizational changes within professional organizations. One recurring observation and experience from health care studies is that it is difficult to discuss the last organizational change with professionals because the most recent change is always perceived as the worst. In order to avoid this routine response, the authors of this article asked 56 senior physicians from the Swedish health care sector what their ideal organization looks like. The authors note that there is a strong institutionalized idea among the physicians of how health care should be organized. The image is not particularly complicated: the organization should be based on the meeting between doctor and patient. One conclusion in the article is that professionals dislike change, but nevertheless, they still want it. Actual change is not the problem – only changes that are not in compliance with the professionals' opinions of organization and management. 相似文献

A wide range of intractable problems such as polluting emissions, noise, accidents, resource depletion, and inaccessibility of amenities are associated with the current transport regime. Given the slow movement towards a more sustainable mobility system, more radical, systemic innovation - a ‘transition’ - is required. Broadly speaking, this may be achieved via three routes: technological change, modal shift, and reduced travel demand. Drawing on concepts from the transitions literature (e.g., [Geels, F.W.: Technological Transitions and System Innovations: A Co-evolutionary and Socio-Technical Analysis, Edward Elgar, Cheltenham, 2005.]), we conceptualise each of these routes as a bundle of niche activities within an Area of Innovation, deviating to differing degrees from the current mobility ‘regime’. We present empirical evidence and indications of ongoing development of niches in these three areas within the UK and Sweden, and explore processes of co-evolution, divergence and tension within and between niches. Findings indicate recent market penetration of novel transport technologies, more advanced than modal shift or demand management activities; however, different transport technologies are more successful in each country. We also identify examples of a close relationship between development of radical vehicle/fuel technologies and provision of mobility services; and information technology as a driver in all three areas of innovation. We conclude that future innovation in transport depends on diversity, hybridisation, and co-evolution of niches. Finally, policy implications are discussed. 相似文献

Little is known about the differences in the relation between risk and return in large economies such as the U.S. compared with smaller, less studied, markets. In this paper, Sweden serves as a representative for small open economies. The price of risk on the Swedish stock market is estimated using a conditional asset pricing model that allows for time variation in the risk. Four different GARCH-M models are used in the econometric specification. The estimates of the price of risk are invariably positive and significant, and we conclude that there exists a time-varying risk premium in the Swedish stock market. Our results show that there are small differences in the preferences towards risk of representative investors in small and large economies. 相似文献

Access to both a local and a global network is needed in order to get complete connection to the Internet. The purpose of this article is to examine the interplay between those two networks and how it affects the domestic public policy towards a domestic provider of local access. We find that a cost-oriented regulation is detrimental to domestic welfare, because it shifts profit to the foreign provider of global access. The optimal policy is that the regulator commits itself to set an access price above costs, possibly the same price as in an unregulated market economy. A regulation of the global access price has a non-monotonic effect on domestic welfare, and there is a potential conflict between international and domestic regulation policy. 相似文献

This paper discusses and contrasts two mainroles of forestry in light of the debate on theglobal climate. As the main problem is relatedto the increases of the CO2-concentrationin the atmosphere, forests may be viewed aspart of the alleviation of the problem throughtheir function as (i) a source of biomass forenergy production, which may replace fossilfuels and thus indirectly reduceCO2-emissions, and as (ii) carbon storage,since a growing forest extracts atmosphericCO2 and fixes it as carbon in biomass. Inthe Scandinavian forestry, logging residues areincreasingly being used for energy production.In this paper the value of forests as a sourceof bioenergy is added to the traditional timbervalue. Formulated as a joint production modelwithin the Faustmann framework, the effect ofthis addition on the optimal rotation length isdiscussed. Based on data for spruce, thedominant species in the Scandinavian forestry,it is demonstrated that the rotation length isshortened compared to the standard Faustmannmodel. Shorter rotation length implies lesscarbon storage. Therefore, in this modelwithout explicit regard to the social carbonstorage value of the forest, the gains in termsof the climate problem from utilisation offorest biomass for energy production are beingdiminished by the value of reduced carbonstorage. The carbon value of the forest is thenadded to complete the model, with the effect ofincreasing the rotation length, a result thatis well known in the literature. Finally, theempirical effects of the interaction of thesetwo climate-related value elements of theforest are discussed. 相似文献
