The aim of this study is to provide a foundation for researchers and managers to discuss and resolve difficulties associated with research and development (R&D) target‐setting. While multiple studies mention the difficulty of R&D target‐setting, few have compiled reasons for these difficulties or addressed this issue in detail. This paper provides one of the first studies outlining reasons for R&D target‐setting difficulties through a literature review. It also provides an initial set of analyses and results after applying an emerging quantitative method, Technology Forecasting Using Data Envelopment Analysis (TFDEA), to illustrate these difficulties step‐by‐step to commercial airplanes. Results include determining the state of art in commercial airplane technology and technological rate‐of‐change variants in setting R&D targets. 相似文献

Building on information processing theory (IPT), this empirical study investigates the factors that drive a buying center's level of sensitivity to brand information. The authors propose that buying center brand sensitivity is related in a curvilinear fashion with purchase importance and purchase complexity, and that these relationships are moderated by several environmental, firm, and product factors. Data provided by 273 organizational buying center members confirm the presence of an inverse U-shaped relationship between purchase importance and brand sensitivity, strengthened in conditions of high brand presence and high end-customer demand. Purchase complexity and brand sensitivity appear to relate in a U-shaped fashion but only in light of the moderating effects of product tangibility. The relationship between purchase complexity and brand sensitivity appears stronger when buying firms are small and have prior contractual ties with their selling partners. These results offer guidance to managers concerning when business-to-business (B2B) brand investments are likely to offer their greatest return. 相似文献

Using data from the 2001 Australian Census of Population and Housing, on adult men in full‐time employment, this paper augments a conventional human capital earnings function with information on occupations. It also estimates models of occupational attainment. The results from both the earnings function and model of occupational attainment indicate that the limited international transferability of human capital skills results in immigrants entering into relatively low status occupations when they first enter the Australian labour market. Comparison with similar research for the USA suggests that the different immigrant selection regimes (primarily family reunion in the USA, skill‐based immigration in Australia) do not impact on the negative association between current occupational status and pre‐immigration labour market experience. 相似文献

This paper provides a survey of the literature on inequality in China – level, change, causes, and consequences. It attempts to answer six main questions. How much has inequality risen? What is its relation to poverty alleviation? What has happened to wealth inequality? What are the main dimensions of rising income inequality? The dimensions examined are: the rural–urban divide; urban labor market reform; regional divergence; rural–urban migration; and entrepreneurship, rent‐seeking, and corruption. Was it inevitable that inequality should rise so much? Does it matter that inequality has risen? Income distribution in China is bound up with both economic reform and economic growth. This paper concludes by considering the countervailing forces that will determine the path of inequality in future years. 相似文献

The conceptual foundations of the Index of Sustainable Economic Welfare (ISEW) are surveyed and critiqued. It is argued that the three underlying theories of community, psychic income, and social welfare economics supply certain theoretical foundations for the ISEW. The focal point of the theories is to evaluate the positives and negatives of economic growth, with the hope of achieving a practical measure of sustainable economic welfare. However, they are not as well developed as they should be: the three theories have partial, underdeveloped explanations of the benefits (services) and costs (disservices) generated in the system. The theoretical particulars of ISEW abstract from the workings of the capitalist system, because the ISEW advocates have not specified a society in the socioeconomic system which we currently have. Specifically, there is no underlying linked systems view of the disembedded economy — where the exchange economy tends to dominate other aspects of culture. Without a systematic understanding of the political economy of capitalism, the ISEW is potentially flawed in design. Therefore, there is a need to search for a critical approach to sustainable economic welfare. As a point of departure, it is better to have a political economy theory. The political economy of the disembedded system provides an alternative theoretical approach to ISEW. 相似文献

Geoscientists are faced with a number of complexities that represent obstacles to the development of realistic simulation of deep earth processes. Realistic 4D thermo-mechanical simulation using software packages like Underworld and Gale, when combined appropriately with geoscientific expertise, can lead to novel insights into the deformation of geological structures at a wide range of time and spatial scales. The challenge for end-user geoscientists lies in applying their knowledge within the framework of the software’s input specification, including initial, internal, and boundary conditions and output visualization parameters. We have built a Graphical User Interface (GUI) to remove many of the difficulties related to editing the Extensible Markup Language (XML) encoded input files of Underworld/Gale geomodels and therefore, to greatly broaden the user base of these software packages. By helping Underworld/Gale to meet a large audience, we provide a tool to the geoscience community that helps to move from untested conceptual models to physically valid, properly scaled modelling. Furthermore, the UnderworldGUI offers a mechanism for storing and retrieving experimental models in a centralised database, thus providing the geoscience community with a means to share the outcomes of its experimental research. Further details of the UnderworldGUI are available at the web site http://www.wiki.vislab.usyd.edu.au/moinwiki/UnderworldGUI. 相似文献

We study auctions with resale based on Hafalir and Krishna's (2008) [6] model. As predicted, weak bidders bid more with resale than without, so that average auction prices tend to increase. When the equilibrium calls for weak types to bid higher than their values with resale they do, but not nearly as much as the theory predicts. In other treatments outcomes are much closer to the risk neutral Nash model's predictions. Bid distributions for weak and strong types are more similar with resale than without, in line with the theory. 相似文献

This paper explores the emergence of biotechnology centers in Shanghai and Bangalore by comparing their development to best practices in the literature for biotechnology cluster growth and development. Interviews with over fifty biotech companies and related institutions in China and India indicate that these regions are developing alternate models of low cost manufacturing and services that build on the current local base of knowledge and expertise. The ability to convert research into successful commercial activity was identified in both regions. The strong research capacity, private sector funding, and entrepreneurial environment deemed critical best practices were limited. New growth theory is used to explain these alternate approaches to technological and social change. 相似文献

We investigate the relative impact of internal Delphi process factors - including panelists' degree of confidence, expertise, majority/minority positioning - and an external factor, richness of feedback - on opinion change and subsequent accuracy of judgmental forecasts. We found that panelists who had low confidence in their judgmental forecast and/or who were in a minority were more likely to change their opinion than those who were more confident and/or in a majority. The addition of rationales, or reasons, to the numeric feedback had little impact upon panelists' final forecasts, despite the quality of panelists' rationales being significantly positively correlated with accurate forecasts and thus of potential use to aid forecast improvement over Delphi rounds. Rather, the effect of rationales was similar to that of confidence: to pull panelists towards the majority opinion regardless of its correctness. We conclude that majority opinion is the strongest influence on panelists' opinion change in both the ‘standard’ Delphi, and Delphi-with-reasons. We make some suggestions for improved variants of the Delphi-with-reasons technique that should help reduce majority influence and thereby permit reasoned arguments to exert their proper pull on opinion change, resulting in forecast accuracy improvements over Delphi rounds. 相似文献

Critics of online labor markets claim that employer abuses are endemic in these markets. Surveying a sample of workers, I find that, on average, workers perceive online employers to be slightly fairer and more honest than offline employers. 相似文献
