This paper presents an approach to assessing the efficacy of public spending on research and development in state programs. At present, there is a need to develop a unified approach to the analysis and evaluation of the efficacy of such spending from the perspective of participants in state programs (federal executive bodies). The proposed approach does not allow evaluating the efficacy of public spending on the development of research areas assigned to the authors.  相似文献

This article presents a medium-term forecast of the development of the Russian nanoindustry, taking into account the assumed transition of the industry from the formation stage to the investment growth stage. Problems associated with the estimated output volumes of products in the Russian nanoindustry are considered, since the trends recorded in the primary statistical data are very far from reflecting the real situation due to the imperfection of the system of statistics of nano-containing products, as well as a reduction of state funding and a decline in the intensity of research in the industry. It is concluded that a full-fledged industry has not been yet completely formed in Russia and it actually exists only as a statistical phenomenon; in addition, the project really set different objectives from the declared creation of a breakthrough high-technology branch.  相似文献

As the hunting, butchering, processing, and consumption of bushmeat is a potential source of human Ebola virus (EV) infections, the extent to which bushmeat is a substitute for food produced and sold in the formal sector suggests that the relative price of food could matter for the incidence of human EV infections. This paper considers if productivity in the food sector is a driver of human EV infections in sub‐Saharan Africa. We estimate count data specifications of country level human EV infections as a function of food sector productivity in sub‐Saharan Africa over the 1976–2013 time period. Our parameter estimates suggest that if productivity in the food sector was on average 1 per cent higher over the 1976–2013 time period, the incidence of human EV infection would have been 42.5 per cent lower. This is consistent with bushmeat being a substitute for food produced in the formal sector, as food productivity increases lower the price of formal food relative to bushmeat. Our findings suggest that as productivity in the formal food sector is a driver of human EV infections in sub‐Saharan Africa, policy interventions that increase food productivity would enable Millennium Development Goal outcomes related to hunger, disease mitigation, and sustainability of wildlife.  相似文献

The Carpathian Basin is one of the most vulnerable European regions in terms of potential climate change impacts on biodiversity. Its wide range of tourism activities make it uniquely suitable for assessing the effects of climate change on tourism. This research sought to create a Tourism Adaptation Portfolio (TAP) for the Szentendre micro-region in Hungary and to assemble an adaptation toolbox for current and future use by tourism organizations. The TAP contains practical, easy to implement solutions for key stakeholders in the sector by adaptation type (technology, management, behavior, education, policy). Surveys of local tourism suppliers showed that 70% said they were well informed, largely by the Internet, but 55% admitted to not knowing enough. The methodology outlined here is transferable and the process can be replicated elsewhere, supporting other regions in becoming climate-friendly tourism destinations, creating opportunities for uniquely positioning a region for consumers. The article provides a concise overview of tourism provider attitudes assessed through a questionnaire, shedding light on points of intervention, willingness to pay, main barriers and suitable adaptation instruments. The adaptive capacity of stakeholders is also discussed, which is indispensable for implementing successful practices in adaptation and maintaining the current level of environmental services.  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

Relationship marketing in consumer markets: Antecedents and consequences   总被引:19,自引:0,他引:19  
Understanding the motivations of consumers to engage in relationships with marketers is important for both practitioners and marketing scholars. To develop an effective theory of relationship marketing, it is necessary to understand what motivates consumers to reduce their available market choices and engage in a relational market behavior by patronizing the same marketer in subsequent choice situations. This article draws on established consumer behavior literature to suggest that consumers engage in relational market behavior due to personal influences, social influences, and institutional influences. Consumers reduce their available choice and engage in relational market behavior because they want to simplify their buying and consuming tasks, simplify information processing, reduce perceived risks, and maintain cognitive consistency and a state of psychological comfort. They also engage in relational market behavior because of family and social norms, peer group pressures, government mandates, religious tenets, employer influences, and marketer policies. The willingness and ability of both consumers and marketers to engage in relational marketing will lead to greater marketing productivity, unless either consumers or marketers abuse the mutual interdependence and cooperation. He has published more than 200 books and research papers in different areas of marketing. His bookThe Theory of Buyer Behavior (1969) with John A. Howard is a classic in the field. He has recently published two scholarly books:Marketing Theory: Evolution and Evaluation (1988) andConsumption Values and Market Choices (1991). He is on the editorial boards of at least a dozen scholarly journals in marketing, international business, and quantitative methods; he is also series editor ofResearch in Marketing (JAI Press). Prior to joining Emory, he was an associate professor of marketing at XLRI Jamshedpur in India. He received his M.B.A. and Ph.D. from Banaras Hindu University, India. He has authored a number of articles in the area of international marketing, business alliances, and environmental marketing. He is coeditor ofResearch in Marketing (Annual Series, JAI Press) and serves on the editorial review board ofInternational Marketing Review.  相似文献

Little research attention has been devoted to the impact of salesperson failure and recovery management on customer relationship development. This paper develops a theoretically anchored and externally validated sales recovery audit for the purpose of assessing sales organization performance in these matters. Results based on a survey of 177 sales managers indicate that practice of sales recovery efforts lags behind their perceived importance as they relate to organizational success. The sales recovery audit presented here can be a useful tool to continuously evaluate and enhance sales recovery efforts for the purpose of building a stronger relationship selling organization.  相似文献
