This paper addresses the issue of R&D programme prioritisation within a manufacturing company in the aerospace industry, in the context of an overall framework for technology management. A review of approaches to R&D project selection leads into a recent case, which describes how the company developed a practical methodology. The benefits of the process and the relevance of the academic contribution are discussed, leading to a practical checklist for in-company development of a prioritisation process.  相似文献

Whilst statistics take up a prominent place in the social science research toolkit, some old problems that have been associated there with have not been fully resolved. These problems include bias through the inclusion of irrelevant variation and the exclusion of relevant variation, which may lead to hidden and spurious correlations in more extreme—however not at all unthinkable—cases. These issues have been addressed by Ragin by building a case for the usage of fuzzy set theory in social science. In this paper, we take a complementary view, insofar as we incorporate fuzzy set theory in current statistical analyses. Apart from shedding new light on the main issues associated with (population based) statistics, this approach also offers interesting prospects for the falsification of theories—rather than single relations between variables—in the social sciences.  相似文献

This paper discusses the entrepreneurial landscape in Africa and locates a new generation of African entrepreneurs and their business networks within it. Unlike others in that landscape (i.e. micro- or small-scale informal sector vendors, and traditional or multinational large-scale formal sector firms), the ‘new generation’ entrepreneurs are business globalists who organized a system of business enterprise networks consisting of national, regional, and pan-African organizations. The study analyses interview data from 57 men and women network members from 10 countries (Botswana, Ethiopia, Ghana, Kenya, Mali, Senegal, South Africa, Uganda, Zambia, and Zimbabwe). Some defining characteristics of these entrepreneurs are interactive social and business relationships, use of modern management methods and information technology, trust among fellow members, transparent business practices, advocacy on behalf of the private sector, and commitment to increasing intra-African commerce. Their mission is to improve the climate for private sector business in Africa and to promote regional economic integration. They pursue cross-national commercial ventures, maintain official observer status at established regional economic organizations, sign memoranda of understanding with multilateral agencies, establish venture capital funds, and help to change government policies. The paper identifies characteristics of the ‘new generation’ entrepreneurs, evaluates goals and achievements of their networks, and concludes that despite limitations, these entrepreneurs and their organizations have created intra- and cross-national networks that strengthen private-sector-led economic growth in Africa.  相似文献

Profiles of exporting and superior-performing private small and medium-sized enterprises (SMEs) are presented. Multivariate regression evidence suggests that SMEs focusing upon an offensive and market differentiation strategy of product/service protection is associated with the propensity and the intensity of exporting. Exporting SMEs are also associated with younger and manufacturing firms as well as firms with product or service quality and/or technology resources. The perceptions by SMEs of external environmental turbulence were not significantly associated with the exporting-dependent variables. Most notably, variables associated with exporting SMEs are not the same as those associated with superior firm performance. Moreover, exporting firms did not report superior levels of performance. Implications for policy-makers, practitioners and researchers are discussed.  相似文献

Abstract

This article examines how far senior staff in English educational and health service organizations view themselves as leaders who are ‘change agents’ for government-driven reform and independent change agendas. The contribution of external leadership development provision to shaping these self-perceptions is explored. Special attention is paid to national leadership development bodies with different degrees of formal association with government. Whatever this relationship, such provision and other development support apparently reinforced a strong sense of personal agency (choice of action) associated with being a leader, empowering senior staff to adopt a modestly mediatory stance towards both reform and leadership development provision.  相似文献

In this paper we problematize the metaphor of balance employed in the area of information privacy. Using Actor-Network Theory we conduct an historical investigation into the continuous release of the same personal data over the course of eight decades. Through the examination of actual enactments of balance over time we find that, in practice, balancing acts are conducted at local levels by local actor-networks within organizations, with limited overall organizational knowledge, raising challenges around interpreting statements made by organizational spokespersons. We also find a surprising lack of knowledge possessed by these local actor-networks about what is subsequently done with personal data and the extent to which networks that extend beyond the organization gravitate towards and form around available data. Through tracing and revealing this historical Actor-Network Theory investigation provides a means of probing and examining actual acts of balance in the area of information privacy and, through revelation, aid in the creation of the possibility of bringing the act of balance more in line with the concept.  相似文献

Establishment of the European Central Bank presents a rare opportunity to define the operations of a central bank without a prior track record. This paper asks what might be learnt from the recent experience of inflation targeting at the Bank of England before the ECB specifies an, as yet undefined, operational target. We consider whether there should be single or multiple targets and which inflation measure should be used, if at all. If inflation is targeted then a forecast of its value becomes the intermediate variable. This raises an issue of transparency and the compensating supply of information necessary to fill the gap, but too much 'openness' can also be problematic. The ECB must be accountable and the contracting approach may be useful although being seen to 'say' and 'do' the same thing is ultimately most important.  相似文献
