This article examines the ecosystem impacts of transgenic Bt cotton technology resulting from reduced chemical pesticide use. Employing unique panel data from smallholder farmers in India, negative environmental and health effects of pesticide use are quantified with the environmental impact quotient (EIQ), with and without Bt technology. An environmentally sensitive dynamic production function is estimated, treating the environmental risk of pesticide toxicity as an undesirable output in the production process. Negative externalities are significantly lower in Bt than in conventional cotton. The reduction in EIQ through Bt technology adoption has increased from 39 per cent during 2002–2004 to 68 per cent during 2006–2008. Bt adoption has also contributed to higher environmental efficiency. Environmental efficiency is influenced by the quality of Bt technology: high‐quality Bt seeds are associated with higher environmental efficiency than lower‐quality seeds. 相似文献

This study introduces the concept of attractiveness similarity, empirically examines its main effect and whether it moderates the effect of endorser attractiveness on consumer responses to advertising. The results show a positive main effect of attractiveness similarity over and above the mere effect of endorser attractiveness. In addition, a consistent moderating effect of attractiveness similarity on the effect of endorser attractiveness emerges: attractiveness similarity buffers against the less positive effects of lower levels of endorser attractiveness (i.e., it compensates for lower levels of endorser attractiveness). Overall, these findings reveal attractiveness similarity as a new variable in endorser advertising, which has important managerial implications. Advertising campaigns employing averagely attractive endorsers should pay special attention to attractiveness similarity. 相似文献

Online advertising has been one of the fastest growing industries worldwide, due to the increased number of Internet users. From the perspective of marketing management, identifying the profile of web users who click online ads will enable designers to create better online advertising campaigns. Hence, the main objectives of this article are (1) to segment web users based on their beliefs about online ads, (2) to identify personality traits of each segment, and (3) to investigate attitudinal and behavioral differences across segments about online ads. Data were collected through an online survey and by using cluster analysis, web users were segmented into three groups based on their beliefs about online ads: “Supporters,” “Neutrals,” and “Opponents.” Personality trait differences as well as attitudinal and behavioral differences among three segments were examined and significant differences were found in terms of their personality traits, such as variety seeking, market mavenism, and innovativeness. 相似文献

Although the original concept of international new ventures included the geographic configuration of value activities, the subsequent development of the literature has gradually abandoned the concern about the geographic configuration of both input sourcing and output marketing to concentrate almost exclusively on the latter. Therefore, this paper argues that there is a need to re-focus the research so as to figure out how and why some companies are borderless. Borderless firms are defined as the result of the combination, early on, of geographically dispersed resources and capabilities, defying the home-base logic. A borderless firm presents the following characteristics (or a combination of them) from inception (or shortly thereafter): (i) value-added activities dispersed across different countries and regions; (ii) entrepreneurs not bounded by a home base; (iii) multinational founders and/or management teams; and (iv) a multinational workforce. To enquiry into this issue, the study uses five case studies of borderless firms. The results advance the understanding of the motives and processes behind the development, early on, of a borderless configuration of value activities. 相似文献

Children’s daily consumption of food in childcare institutions has an impact on their public health nutritional status. The collaboration of parents and employees of kindergartens is important to ensure healthy eating habits among the next generation. Consequently, evaluations of lunch schemes are important to provide a good foundation for enhancing communication between home and institutional settings. The aim of this article is to assess parental satisfaction and identify themes related to parental perceptions of lunch schemes in Danish kindergartens. A survey was developed and distributed in four kindergartens with lunch schemes. A combination of closed and open questions were used to evaluate satisfaction and identify positive and negative aspects of the lunch schemes. Parents of 93 children participated in the study and the response rate was 55%. Eighty-nine percent expressed satisfaction with their children’s lunch scheme. According to parents, the most positive aspects were that lunch schemes serve a variety of food, their ability to prevent neophobia, that children learn that eating is a social occasion, and that the arrangements offer convenience to parents. The negative aspects identified were the lack of communication between the kindergarten childcare institutions and the parents regarding the food. Overall, parents are very satisfied with their children’s lunch schemes; however, the information between institutions and parents could be improved. 相似文献

During many manmade and natural crises such as terrorist threats, floods, hazardous chemical and gas leaks, emergency personnel need to estimate the time in which people can evacuate from the affected urban area. Knowing an estimated evacuation time for a given crisis, emergency personnel can plan and prepare accordingly with the understanding that the actual evacuation time will take longer. Given the urban area to be evacuated, street widths exiting the area's perimeter, the area's population density, average vehicle occupancy, transport mode share and crawl speed, an estimation of traffic evacuation time can be derived. Peak-hour traffic data collected at three, midblock, Mumbai sites of varying geometric features and traffic composition were used in calibrating a model that estimates peak-hour traffic flow rates. Model validation revealed a correlation coefficient of +0.98 between observed and predicted peak-hour flow rates. A methodology is developed that estimates traffic evacuation time using the model. 相似文献

This article defines the marketing concept in a traditional way, but extends its application to high-technology products. Dennis Cahill, Sharon Thach, and Robert Warshawsky present two case studies of high-technology products. Both products were ultimately market failures; however, the analysis presents one as a successful application of the marketing concept, contrasting sharply with the other. 相似文献

This paper is about the creation of non-commodified volunteer experiences, for tourists and local volunteers participating in festivals. How is the tourist experience created when most of the traditional tourism demands are not fulfilled? And what are the experiences and how do they relate to different ‘regimes of value’? The experience context includes tourists who work together with locals voluntarily in a festival, where the volunteers pay for their own travel, food, overnight stay, and work for free. To gain more knowledge on the volunteers is important because local cultural life becomes more festivalized, most festivals are reliant on the involvement of volunteers, and the festivals gain an important role in an economy where even small places are engaged in branding [Löfgren, O. 2003. The new economy: A cultural history. Global Networks, 3, 239–254]. This paper uses a qualitative approach. Interviews were conducted (n?=?23) and participants were observed during four festivals in Finnmark, Norway. Nothing in the experiences was facilitated, and the experience creation occurred in the work tasks together with volunteer colleagues. It was like a holiday experience, without a stream of commodified moments. It was a value creation that could be seen as authentic and real, created in the interaction between the local and visiting volunteers. 相似文献
