This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas.  相似文献

Characterization and construction of optimal designs using the familiar optimality criteria, for example A-, D- and E-optimality are well studied in the literature. However the study of the Distance Optimality (DS-) criterion introduced by Sinha (1970) has very recently drawn attention of researchers. In the present article, we consider the singularly estimable full rank problem of estimating the full set of elementary treatment contrasts using the DS optimality criterion in the set up of a one way ANOVA model. Using a limit argument it turns out that a CRD in which difference between any two allocation numbers is at the most unity is uniquely DS-optimal. Acknowledgement. We are thankful to Prof. B. K. Sinha for suggesting the problem to us and many helpful discussions with him. We are also thankful to the referees for drawing our attention to the reference of Bischoff (1995) and many helpful comments.  相似文献

One hundred and fifty‐eight bankers, accountants and corporate lawyers, aged under 40 years, earning more than £50,000 annually and working in the City of London were questioned about their attitudes and behaviour in relation to charitable giving. A conjoint analysis of the respondents' preferences revealed strong predilections for certain types of charitable organisation; for ‘social’ rewards in return for donating (invitations to gala events and black tie dinners for example); and for well‐known charities with established reputations. ‘Planned giving’ whereby donors receive tax breaks and other financial incentives to donate (as increasingly practised in the USA) did not represent a significant inducement to give so far as this particular sample was concerned. Overall the results suggest that young affluent male City employees constitute a distinct market segment for charity fundraisers, with unique characteristics that need to be addressed when developing donor products.

This article explores the role of business incubators on the innovation performance of start‐ups; in addition, we also investigate how the incubation effect moderates other important factors driving their innovation performance. The empirical evidence comes from a sample of firms located in Northern Italy belonging to the manufacturing (mechanical engineering firms) and service sectors (knowledge‐intensive business services). The results suggest that the incubation effect is very important in shaping the innovation performance of new ventures (measured as a percentage of sales of new‐to‐market innovations). Moreover, it positively moderates the impact of (1) the internal technical capabilities and (2) the adoption of a limited portfolio of collaborations for innovation.  相似文献

The empirical literature on international trade predicts that internationally involved firms experience a productivity premium when compared to domestic firms. This finding is supported by comparing the unconditional productivity averages or distributions, or regressing the productivity on the international status dummy, controlled for the relevant covariates. In the present paper, we disentangle the distribution of the gross productivity premium from the component that is created by the different structural compositions of the two groups of firms; we can thereby measure the distribution of the net premium that is attributable to internationalisation. To this purpose, we use the quantile decomposition methodology ( Melly, 2005 ). The main results highlight that (i) the net premium is substantially lower than the gross premium and (ii) while the difference in the gross premium is uniform along the entire distribution, the net premium is significant only for the less productive firms. These results are confirmed even if different internationalisation modes are considered (i.e. exports, agreements and commercial penetration) using the domestic firms as baseline. One exception is the net premium for firms enrolled in foreign direct investment and/or offshoring; this premium does not decrease for firms at the top of the productivity distribution.  相似文献

Based on a random sample of employees (n = 391) working in various industrial sectors in the United States, we examined the respective linkages between employee–organization relationships (EORs) and authentic leadership, symmetrical internal communication, and organizational culture. Results indicated that authentic leadership, organizational culture of supportiveness, emphasis on reward, and stability were significant predictors of the symmetrical internal communication system of an organization and EORs. Symmetrical internal communication cultivates quality EORs and mediates the effects of authentic leadership and cultural dimensions of supportiveness on EOR outcomes. The theoretical and practical implications of the findings were also discussed.  相似文献

Modern science is characterized by an increasing trend in collaborations and interactions among researchers. This paper aims to analyse the effects of this phenomenon on the productivity of the science sector and on the growth rate of the economy. Basic research is modelled as a contest where only those who arrive first at an innovation obtain the reward and where the interactions among researchers do contribute to production of scientific knowledge. An important result is that when interactions are significant multiple steady states emerge. Hence the ‘science globalization’ process could have enhanced the heterogeneity among scientific sectors of different countries. When there are low interactions, policies that increase connectivity could have low or even perverse effect at improving the efficiency of science, the contrary happens in high connectivity environments.  相似文献

Interest in the managerial practices of females in business has increased over the past decade due to women's increased representation in business. Anecdotal evidence has suggested that women approach decision making differently from men. The purpose of this study is to determine if gender differences regarding managerial strategies exist in the retail setting. Targeted managerial strategies focused on short-term planning processes (personnel, financial, inventory and market planning) and competitive strategies in operation (differentiation, cost leadership and focus). In a sample of 459 retailers from a twelve-state region, MANOVA was used to determine if significant differences in managerial strategies existed between genders. The data on retail competitive strategies suggest that men and women more likely than male business owners to recognize in the importance of differentiation and focus as retail competitive strategies in their business operations. Gender differences were also found in the operational planning areas of market and inventory planning.  相似文献

Abstract

Characteristics of implied-superiority claims that mislead consumers were examined. Claims for four products were investigated using a factorial design to manipulate type of claim (three variations of implied-superiority claims and a noncomparative claim), concreteness of the referent attribute (concrete, vague, and omitted), and brand familiarity (familiar and fictitious brand names). Implied-superiority claims were more misleading than noncomparative claims, as shown by the percentage of subjects who believed that brands described by such claims were superior. Ratings of brand quality and interest in trial were not increased by such claims. Concreteness of referent attributes does not account for these findings; however both the use of indirect comparisons to competitors and the use of familiar brand names contribute to the misleading effects of implied-superiority claims.  相似文献

A Cross-Country Database for Sector Investment and Capital   总被引:1,自引:0,他引:1  
This article presents a new database of investment and capitalin agriculture, manufacturing, and the overall economy. It covers62 industrial and developing countries for the years 1967–92.A common method is used in the calculations to facilitate comparisonsacross countries and sectors. The sensitivity of the calculationsto choices of parameters and estimation methods is tested. Collectively,the data show that as economies grow, capital stocks accumulate,but the composition of capital changes. Together and individually,capital stocks in agriculture and manufacturing constitute asmaller share of the total capital stock than they did 20 yearsago. Capital-labor ratios show that agriculture has become morecapital intensive in most countries. The composition of agriculturalcapital has changed as well; capital from investments in orchardsand livestock has declined relative to capital from fixed investmentsin machinery, irrigation, and buildings.  相似文献
