Rudy Moenaert, William Souder, Arnoud De Meyer, and Dirk Deschoolmeester report the results of their study of forty technologically innovative Belgian companies to examine the interaction between marketing and R&D. They studied one commercially successful and one commercially unsuccessful technological product innovation project in each participating company and collected data from one marketing and one R&D respondent per project. Communication flows between marketing and R&D are increased under conditions involving formalization of projects, decentralization, positive interfunctional climate, and role flexibility.  相似文献

This paper is concerned with one central question: the choice between theories, and the role played by data in that choice. It deals with the uses economists may make of data and the importance of understanding the institutional basis that gives rise to the data - an area in which labour economists have traditionally been particularly strong - and with the relevance of assumptions. It deals with the ultimate need to choose between competing theories (despite the role of conventionalism) on the basis of data rather than retreating into a comfortable 'methodological pluralism'. It considers the role of test replication, with reference to the practice in natural science (and its role there in checking scientific fraud) and concludes that, despite extensive technical problems of testing, economists have to accept a data check if the rhetoric of mathematical technicality is not to overwhelm the need to explain. Parallels are drawn with experience in physics (and the implications of the development of Chaos and Catastrophe for a naively predictionist view are noted), medicine and history (of which, it is argued, modern economists are far too neglectful).  相似文献

Commercial project management systems focus on preproject planning and after-the-fact documentation, but not on the dynamic problem solving required in day-to-day project management. Yet the need for risk-oriented management is clear. To understand and control project risks, managers must be able to identify problems as they occur, immediately assess their downstream impacts, and plan a course of action. The Advanced Risk Management System (ARMS) is a prototype system built to address the issues of identifying, analyzing, prioritizing, monitoring, and controlling project risk. ARMS uses expert systems, data base management, and hypermedia technologies to capture and classify project schedule problems, to determine their semantic impacts to future activities, and to alert appropriate project personnel in advance of problem occurrence.  相似文献

This paper examines occupational performance in Australia across three racial groups in Australia: Indigenous Australians; Asian people, defined as all those whose language spoken at home was either Chinese, Vietnamese or other forms of a South-east or East Asian language; and white people, defined as the residual category. The paper has as its starting point, observed differences in occupational attainment among the three groups in Australia and sets out to account for these observed differences on the basis of both race and non-racial attributes such as, age, education and area of residence.  相似文献

In this paper, we examine the impact of managerial self-interest on the value of multinationality. Since agency theory also suggests that a divergence between the interests of managers and shareholders can be aligned by effective managerial incentive, we also examine the effect of managerial compensation on the value of multinationality. Our results show that for high- Q (Tobin's Q > 1 ) firms, investors do not associate the spending of free cash flow on multinationality with the problem of overinvestments. For high- Q firms, it is also found that the value of multinationality can be enhanced by effective managerial incentives. For low- Q firms (Tobin's Q < 1 ), it is found that the concern of managerial self-interest overwhelms the benefits of internalization, making multinationality a value-decreasing event. For low- Q firms, managerial compensation is also ineffective in promoting value-enhancing foreign direct investments.  相似文献

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees.  相似文献
