Globalization and technological advances are driving organizations to extend the boundaries of new product development (NPD) teams from traditional colocated settings to dispersed or virtual settings. Virtual NPD teams have a wide array of information and communication technologies (ICTs) at their disposal. ICTs allow team members to communicate and collaborate as they cope with the opportunities and challenges of cross‐boundary work. The purpose of this paper is to explore ICT use by members of virtual NPD teams. This study presents an exploratory test and integration of two competing perspectives of media use in virtual teams: media capacity theories and social dynamic media theories. Specifically, this paper examines the role of task type, organizational context, and ICT type as critical contingency variables affecting ICT use. It also examines how different patterns of ICT use relate to individual perceptions of team performance. The findings from this study of 184 members of virtual NPD teams in three global firms suggest that communication via ICTs in virtual NPD teams is contingent on a range of factors.  相似文献

Livestock form key components of the livelihood strategies of many of the world's poorest people. However, despite the potential to alleviate poverty and improve food security through livestock development interventions, the lack of smallholders' participation in the planning and design of breeding programs has often been a major cause of the failure of such programs. Particularly in developing countries where livestock production is still mostly subsistence-oriented and livestock fulfil manifold functions a considerable number of livestock breeding programs have failed. The development of adequate tools to characterise these functions, bearing in mind that these are expressed only rarely in properly functioning markets, is therefore important.This paper seeks to advance the application of such methodologies to the smallholder pig sector in Vietnam. A choice experiment was applied across 140 households involved in pig breeding in order to assess farmers' preferences and the trade-offs for a list of adaptive and productive traits. These included growth, reproduction, disease resistance, feed requirements and appearance.The findings indicate that smallholders highly value both adaptive and performance traits, particularly in resource-driven (i.e. subsistence) production systems. Performance traits were more highly valued in the demand-driven (i.e. market-oriented) systems. These findings have implications for breeding program breed choice and breeding objectives.  相似文献

It is largely recognised that fiscal policy will have largerresponsibilities for cyclicalstabilisation in EMU given the loss of the monetary instrument.At the same time, theEMU's budgetary framework emphasises the need to rely onautomatic fiscal stabilisers,rather than active policies in cushioning the business cycle.We show that automaticstabilisers are relatively powerful in the event of shocksto private consumption, but lessso in the case of shocks to private investment and exports.In the case of supply sideshocks, the automatic stabilisers are largely ineffective,but this may actually be a goodthing to the extent that supply-side disturbances call forstructural adjustment rather thancyclical stabilisation.  相似文献

According to the National Traumatic Occupational Fatalities (NTOF) surveillance system, occupational injuries claimed the lives of over 100,000 American workers from 1980 to 1997. Previous estimates presented aggregate values of life, providing no information on the cost variations for different case or worker characteristics. This research developed an interactive computer program that estimates comprehensive national costs for all occupational fatal injuries reported through NTOF, nearly $85 billion for 1980–97, and specific estimates for the burden on selected groups and characteristics of the fatality. These estimates provide an additional basis for targeting and evaluating the effectiveness of investments in prevention of occupational fatalities. (JEL I18 )  相似文献

Since 1993 Young & Rubicam has invested over $130 million in collecting and interpreting data on consumers' perceptions of some 44,000 product and service brands in over 50 countries. At the core of Y&R's research effort is the Brand‐Asset® Valuator (or “BAV”), a model that converts the firm's hoard of data on global consumer perceptions and behavior patterns into assessments of brand strength and value. When combined with the findings of independent research by academics in marketing and finance (using Compustat data on corporate operating and stock‐price performance), the BAV's assessments of brand values can be used to quantify the contributions of brands to both corporate earnings and market values. One of the main findings of this research is that brands contribute to the market value of companies by increasing not only current earnings, but the price‐to‐earnings (P/E) multiples that investors assign to current earnings. Such increases in P/E multiples in turn reflect investors' expectations for lower risk, higher growth or both. At the same time, more recent consumer surveys (conducted in 2005‐2007) provided indications of brand “erosion” even as the markets were pushing up share prices, presumably with the expectation that intangibles like brand would continue to drive operating earnings in the future. For the leaders of consumer‐related corporations, the resulting “disconnect” between stock prices and brand values points to a continuing challenge for brand management. Building brand value is important for both finance professionals trying to increase shareholder value and marketers trying to build brand strength and increase sales and margin. The aim of the authors' research is to bring these two groups—finance and marketing— closer together by demonstrating the role of marketing strategy and brand equity in driving shareholder value.  相似文献

Criminal investigation and prosecution of politicians, top civil servants and other public figures are topics frequently discussed in the media. The nature of the investigating or prosecuting authority varies between countries – from the general public prosecutor, through magistrates to independent counsels or parliamentary investigation commissions. This paper analyzes the role and status of public prosecutors within the separation of powers-concept. Prosecutors are usually part of the executive and not the judicial branch, which implies that they do not enjoy the same degree of independence as judges, and are ultimately subordinated to the directives of the minister of justice or the government. Conflicts of interest may hence arise if members of government can use the criminal process for their own or partisan interests. The incentives of public prosecutors in different jurisdictions are compared.  相似文献

The purpose of this paper is to contrasts four different multivariate methods; multiple regression using principal components, factors analysis, discriminant analysis involving another use of principal components, and canonical correlation. The method adopted to compare and constrast the techniques is to make careful note of the assumptions involved in each model and to apply each form of analysis to variables drawn from the same set of data.  相似文献

Risk,uncertainty and the theory of planned behavior: A tourism example   总被引:1,自引:0,他引:1  
The differential impacts risk and uncertainty have on travel decision-making were explored by examining the constructs' influence on the antecedents of intentions to visit Australia using the theory of planned behavior. Respondents were obtained from online consumer panels in South Korea, China and Japan. The South Korean and Chinese samples were general population samples, while the sample from Japan was an international travelers' sample. The extended model fitted the data well, explaining between 21 and 44 percent of the variance in intentions. Subjective norms and perceived behavioral control significantly impacted on intentions in all country samples, whereas attitudes toward visiting Australia were only significant in Japan. Subjective norms influenced attitudes and perceived behavioral control in all country samples. Finally, perceived risk influenced attitudes toward visiting Australia in South Korea and Japan, while perceived uncertainty influenced attitudes toward visiting Australia in South Korea and China and perceived behavioral control in China and Japan.  相似文献

Authorities working on economic-crime investigation in Finland are trying to change their form of collaboration from the sequential passing of documents towards parallel, interorganizational collaboration: the on-line investigation of an ongoing crime. The synchronization of events and the outputs of various participants proved to be difficult in this emerging process. This new model of crime investigation also requires a new kind of time management. This article explores how the change is being constructed in everyday practice by examining three economic-crime-investigation cases. It is claimed that individual efforts to manage time allocation suffice only in terms of co-ordination of events. It is suggested that a successful shift to parallel, interorganizational collaboration requires more than the common marking of calendars. The object of the work and the forms of interaction should be taken as subjects of reflective negotiation. New kinds of collective time-management tools are needed in this effort.  相似文献
