The purpose of this study was to identify the relevant factors influencing stakeholders' attitudes toward the transfer of an animal (mouse) gene into rice for vitamin C enhancement. A survey was carried out on 434 respondents from various stakeholder groups in Malaysia. Results of the survey have confirmed that attitudes toward cross-kingdom gene transfer, such as genetically modified (GM) rice, are the result of a complex decision-making process that involves the cumulative interaction of various factors. The most important direct predictors of a positive attitude toward GM rice were specific application-linked perceptions about the religious acceptability and risks of such rice. The attitude toward GM rice also involves interplay between other factors, such as familiarity and the perceived benefits of GM rice, and more general attitudinal variables, such as moral beliefs about biotechnology, attitudes toward labeling, attitudes toward patenting, attitudes toward nature, and confidence in biotechnology regulations. 相似文献

Transgenic Bt cotton has been planted in China since 1997 and, in 2009, biosafety certificates for the commercial production of Bt rice and phytase corn were issued by the Chinese government. The public attitude in China toward agricultural biotechnology and genetically modified (GM) crops and foods has received considerable attention worldwide. We investigated the attitudes of consumers, Bt cotton farmers and scientists in China regarding GM crops and foods and the factors influencing their attitudes. Data were collected using interview surveys of consumer households, farmer households and scientists. A discrete choice approach was used to elicit the purchase intentions of the respondents. Two separate probit models were developed to examine the effect of various factors on the choices of the respondents. Bt cotton farmers had a very positive attitude because Bt cotton provided them with significant economic benefits. Chinese consumers from developed regions had a higher acceptance and willingness to pay for GM foods than consumers in other regions. The positive attitude toward GM foods by the scientific community will help to promote biotechnology in China in the future. Our survey emphasized that educational efforts made by government officials, the media and scientists can facilitate the acceptance of GM technology in China. Further educational efforts will be critical for influencing consumer attitudes and decisions of government agencies in the future. More effective educational efforts by government agencies and public media concerning the scientific facts and safety of GM foods would enhance the acceptance of GM crops in China. 相似文献

The development of novel foods produced through agricultural biotechnology is a complex three-stage process: gene discovery, line selection, and product advancement to commercialization. The safety of genetically modified foods is an integral part of the overall developmental process throughout all of the stages. In the discovery stage, the safety of the gene, its source, and the gene products must be considered. If any questions arise at this stage, these questions must be answered later in the developmental process. During the line selection stage, the genetically modified seed progresses through a variety of greenhouse and field trials. At this stage, the biological and agronomic equivalence of the genetically modified crop to its traditional counterpart must be compared. While the evaluations made during this stage are not specifically directed toward a safety assessment, many potential products with unusual characteristics are eliminated during this stage of development. However, the elimination of products with unusual agronomic or biological characteristics enhances the likelihood that a safe product will be generated. Finally, in the pre-commercialization stage, the genetically modified product undergoes a detailed safety assessment process. This process focuses on the safety of the gene products associated with the introduced gene and any other likely toxicological or anti-nutrient factors associated with the source of the novel gene and the crop to which it was introduced. The safety of the genetically modified product for both food and feed uses is considered. Thus far, all of the genetically modified products brought into the marketplace have been subjected to such an intensive safety assessment. The safety assessment data have been reviewed by regulatory authorities around the world. The current generation of genetically modified products are quite safe for human and feed animal consumption. 相似文献

Recombinant DNA technology offers opportunities to develop new products in many different fields, including agriculture and the agro-food area. Transgenic plants with improved agronomic traits currently grow in field trials and a few varieties have already reached the European market. By and large, new technologies raise both concerns and expectations and modern biotechnology is no exception. Indeed, a voluntary moratorium on experiments involving recombinant DNA molecules was called for in 1974. At the present time, although a majority of academic and industrial scientists agree that transgenic food crops pose no risk for the environment or human health, some others believe that certain applications of modern plant biotechnology are hazardous. In particular, deliberate releases of genetically modified plants are regarded as risky. There is also a disparity between expert and lay perception of r-DNA technology applications to food crops, which makes public information a difficult task. This paper aims at exposing these conflicting points of view on the agricultural applications of modern biotechnology. We also propose some recommendations pertaining to public information in Europe. It appears that consensus conferences might be a good approach to stimulate public information and public debate in Europe, although this approach has to be adapted to the cultural context of each country. 相似文献

The numerous food crises that Europe has experienced during the past five years have raised new consumer demands concerning the characterization, traceability, and safety of foods which are proposed on the market. The consumer has, at the same time, vigorously placed into question the modes of agricultural production in industrialized countries, as well as the structures and means of evaluating the food risks and the conditions of the consumer's participation in the public debate in these domains. For certain groups of consumers, one also attends a contestation of the expertise and the application to the food domain of the considerable progress that has taken place in the field of biotechnology. So it is that the development of genetically modified organisms (mainly plants, the raw material of food products) has experienced a slowing down in the European Union. The answers afforded to these new exigencies of consumers in matter of identity, traceability, and acceptability of the foods are dealt with in this paper, as well as the elements which may concur with the evaluation of their safety. The positive role that biotechnology can afford to the different domains is emphasized. A source of uneasiness, biotechnology is also a powerful tool for ameliorating the evaluation of the sanitary risks and for answering the hopes of the citizen in the food domain. 相似文献

In assessing the likely demand for biotechnology products it is not sufficient just to look at what is happening in firms and their immediate market environment. There is no one 'market' for biotechnology products: there are differences between sectors and between countries. You have instead to look at the institutional contexts of the biotechnology product's development. This paper reviews work which has been carried out by social scientists, especially those using 'social shaping' approaches, on the development of new products based on advances in biotechnology and on the creation of markets to go with these products. It examines work on public attitudes to the exploitation of the technology, focusing especially on the issue of social inclusion and exclusion and how biotechnology might make exclusion more likely. It concludes by considering what current differences in public attitudes to the development of some biotechnology-based products might mean for the development of markets for those products in the UK. 相似文献

Agricultural biotechnology is concentrated in four major countries. This paper suggests strategies for developing it in small countries, based on analysis of the world trends and the characteristics of small countries. Israel is presented as a specific case study. The main relevant trends are domination by big companies, consumer concerns on genetically modified foods, and focusing on consumer benefits and specific market niches. Small countries' disadvantages include companies that are too small to benefit fully from research, difficulty in raising funds, lack of infrastructures and experienced management personnel, and public sector research organizations that are unsuitable for commercializing research. The recommended strategies include: developing a large number of low-volume products and small market niches, forming partnerships with intermediaries (such as food companies), specializing in intermediate products (such as the seed or the gene patent), and conducting market research and cost-benefit analysis in advance. Additional strategies include developing benefits that are unique to genetically modified foods and focusing on benefits specifically for consumers who accept genetically modified foods, rather than on benefits for the average consumer. A national representative organization could buy and rent out expensive equipment, finance specific projects in return for the commercial rights, and perform collective marketing research and marketing. Israel has the advantages of a successful agricultural sector and complementary scientific research, and should focus on those fruits, vegetables, and flowers for which it already has the experience and infrastructure. 相似文献

Biotechnology products and European consumers 总被引:3,自引:0,他引:3

More than 100 interviews conducted during 1997 with European food manufacturers and retailers, trade associations, government departments, consumer groups, environmental organizations and some individual academic scientists revealed how differences in the perceived attitudes of consumers gave rise to varying approaches by suppliers to the possible introduction of transgenic foods. European consumers generally are not against the pharmaceutical products of biotechnology but are much less willing to accept food and food ingredients, especially when derived from genetically modified plants. Objections are mainly based on fears for the health and safety of the consumer, worries about the possibility of deleterious effects on the environment, and a range of moral and ethical concerns often deriving from a distaste, however expressed, at the concept of interfering with nature. Consumer understanding of the science underlying biotechnology is patchy; in no country does more than a small proportion of the population claim a good grasp. Partly no doubt as a consequence of these attitudes, the introduction of genetically modified foods into Europe has occurred slowly and, during the period of this study, perhaps only in the Netherlands and the UK. 相似文献

Affect, associations, and images associated with food technologies may be important factors influencing consumers’ perception of and willingness to accept new food technologies. The aim of the present study was to investigate free associations evoked by the term “biotechnology” and how they influence behavior. Therefore, participants (N = 632) were asked to name three associations they had in mind when confronted with the term “biotechnology.” After that, respondents indicated how positive or how negative these associations were. Additionally, an equivalent gain task was used to measure participants’ behavioral intentions related to genetically modified (GM) chocolate. Results of a log-linear analysis and a correspondence analysis suggest that attitudes toward biotechnology result in a wide range of associations. Participants having negative attitudes mentioned images related to the environment and industry more often compared with participants having positive attitudes. Results of the equivalent gain task show that willingness to buy GM chocolate can be predicted by the subjects’ three reported associations (p < .001), as well as by their gender (p = .003). The model explains 33.5% of the variance. Affect related to people's associations with gene technology strongly influenced their acceptance of GM foods. 相似文献

A recent study by Lusk suggests that consumers might voluntarily pay more for a genetically modified (GM) food than a non-GM equivalent if made aware of the possible health benefits. However, other research indicates that the acceptability of novel hazards is affected by a variety of factors, in addition to benefits, and that making agricultural biotechnology publicly acceptable will be more complex than indicated by the results from Lusk's study. 相似文献

The public's major concern over the introduction of genetic engineering into the food chain focuses on potential health risks. Proving that a food is safe is an impossible goal since there will always be a risk associated with eating food. Diets that are natural in every sense of the word pose risks but the general public believe that they are inherently less risky. The differences in risk between foods that are natural, as opposed to foods that are produced by the application of technology, are likely to be minute. Nor does it follow that they all lie in favour of `natural' food. The fact is that all foods pose a balance of risks and benefits but the scientific method has so far not been applied to its measurement. Only risk is emphasised and estimated, albeit with many conservative assumptions, often resulting in an emphasis on minute risk. Conventional plant products are not subject to the rigorous risk evaluations that apply to genetically modified plants. So the outcome is that the public only receive part of the information and this is the emphasis on risk of the `artificial' food. The only future for foods produced by biotechnology in Europe is if the public are persuaded of the real health benefits that will result from its application. Given the present state of nutritional knowledge, and the limited resources that are given to it, there are only a few clear examples of where nutritional improvement of plant food would bring really significant benefits. The paper highlights these with examples and indicates where further nutritional research will be required before other targets for improvement can be realised. 相似文献

The study of community attitudes toward welfare and welfare recipients is an area of increasing interest. This is not only because negative attitudes can lead to stigmatization and discrimination, but because of the relevance of social attitudes to policy decisions. We quantify the attitudes toward welfare in the Australian population using attitude data from a nationally representative survey (N = 3243). Although there was broad support for the social welfare system, negative attitudes are held toward those who receive welfare benefits. Using canonical correlation analysis we identify multivariate associations between welfare attitudes and respondent demographic characteristics. A primary attitudinal dimension of welfare positivity was found amongst those with higher levels of education, life instability, and personal exposure to the welfare system. Other patterns of negative welfare attitudes appeared to be motivated by beliefs that the respondent’s personal circumstances indicate their deservingness. Moreover, a previously unidentified and unconsidered subset of respondents was identified. This group had positive attitudes toward receiving government benefits despite having no recent experience of welfare. They did, however, possess many of the characteristics that frequently lead to welfare receipt. These results provide insights into not only how attitudinal patterns segment across the population, but are of relevance to policy makers considering how to align welfare reform with community attitudes. 相似文献

Summary Over the past 20 years, DNA-based biotechnologies have been applied to agricultural production and many crops with new and
useful attributes have been cultivated in various countries. The adoption of this new technology by farmers has been swift,
and benefits in terms of increased production per unit land and environmental benefits are becoming obvious. In forestry,
the application of biotechnology is somewhat lagging behind and to date there are no commercial plantations with genetically
modified trees. However, most tree species used in plantation forestry have been genetically transformed, and results demonstrate
the successful and correct expression of new genes in these plants. At the same time, this new technology is being viewed
with concern, very similar to the concerns voiced over the use of genetic engineering in agriculture. This paper discusses
some of the issues involved for world forestry, with particular focus on future demand for timber and timber products and
how modern biotechnology can contribute to meet the growing demand. Tree genetic engineering techniques will be outlined,
and results reviewed for a number of species. Concerns over the use of this new technology will be described and analyzed
in relation to scientific considerations. 相似文献

The pig industry is struggling with negative attitudes of people toward sow husbandry. To be able to respond to these attitudes, the pig industry first has to understand people’s attitudes. The first objective of this study was to determine the attitudes of Dutch people toward sow husbandry with regard to animals, humans, and the environment. The second objective was to group people based on their attitudes toward sow husbandry and determine and compare the socio-demographic characteristics of these groups. An online survey was conducted in the Netherlands and there were 1,607 respondents. On average, respondents had negative attitudes toward all issues defined in this study. The most negative attitudes were toward the effect on both animals and consumers of the use of antibiotics, the number of animals kept per square meter, the possibility for animals to go outside, food safety risks, public health risks, and environmental waste. The findings indicate the importance of considering all the issues identified in this study during the process of developing measures to improve people’s attitudes toward sow husbandry. Respondents could be divided into four clusters; each cluster represented different attitudes toward sow husbandry and had different socio-demographic characteristics. This makes it possible for the pig industry to assign people with specific socio-demographic characteristics to one of the clusters and predict their attitudes toward sow husbandry. Knowledge of these attitudes enables the pig industry to predict how different groups of people will respond to different animal welfare measures. Results of this study are therefore useful for the pig industry to help improve people’s attitudes toward sow husbandry. 相似文献

The very term ‘Biotechnology’ elicits a range of emotions, from wonder and awe to downright fear and hostility. This is especially true among non-scientists, particularly in respect of agricultural and food biotechnology. These emotions indicate just how poorly understood agricultural biotechnology is and the need for accurate, dispassionate information in the public sphere to allow a rational public debate on the actual, as opposed to the perceived, risks and benefits of agricultural biotechnology. This review considers first the current state of public knowledge on agricultural biotechnology, and then explores some of the popular misperceptions and logical inconsistencies in both Europe and North America. I then consider the problem of widespread scientific illiteracy, and the role of the popular media in instilling and perpetuating misperceptions. The impact of inappropriate efforts to provide ‘balance’ in a news story, and of belief systems and faith also impinges on public scientific illiteracy. Getting away from the abstract, we explore a more concrete example of the contrasting approach to agricultural biotechnology adoption between Europe and North America, in considering divergent approaches to enabling coexistence in farming practices. I then question who benefits from agricultural biotechnology. Is it only the big companies, or is it society at large – and the environment-also deriving some benefit? Finally, a crucial aspect in such a technologically complex issue, ordinary and intelligent non-scientifically trained consumers cannot be expected to learn the intricacies of the technology to enable a personal choice to support or reject biotechnology products. The only reasonable and pragmatic alternative is to place trust in someone to provide honest advice. But who, working in the public interest, is best suited to provide informed and accessible, but objective, advice to wary consumers? 相似文献

The history of modern biotechnology of agricultural plants is briefly considered in the article. Methods of genetic transformation and regeneration of transgenic plants as well as the mechanisms of resistance of genetically modified plants to herbicides and pests are discussed. By the example of genetically modified varieties and hybrids there are shown the ways of solving the problem of weeds and pests. The questions of biosafety legislation in different countries are considered. 相似文献

A telephone survey of public attitudes toward organ donation and transplantation was conducted in a community in southwestern Ontario. The subjects were selected at random; the response rate was 57%. Of the 50 respondents 62% stated that they had signed the organ donor card accompanying their driver''s licence. These respondents were more likely than those who did not sign it to have discussed organ donation with their families. At least 80% of the respondents said they would agree to donate their organs and those of their next-of-kin, and 80% said that the organ donor card should be considered a legal document. Organ transplantation was regarded by all but one respondent as an acceptable medical procedure. Also discussed were concerns about organ donation and possible strategies to improve the availability of organs for transplantation. 相似文献

The objective of this paper is to assess the attitude of Malaysian stakeholders to genetically modified (GM) salmon and to identify the factors that influence their acceptance of GM salmon using a structural equation model. A survey was carried out on 434 representatives from various stakeholder groups in the Klang Valley region of Malaysia. Public attitude towards GM salmon was measured using self-developed questionnaires with seven-point Likert scales. The findings of this study have confirmed that public attitudes towards GM salmon is a complex issue and should be seen as a multi-faceted process. The most important direct predictors for the encouragement of GM salmon are the specific application-linked perceptions about religious acceptability of GM salmon followed by perceived risks and benefits, familiarity, and general promise of modern biotechnology. Encouragement of GM salmon also involves the interplay among other factors such as general concerns of biotechnology, threatening the natural order of things, the need for labeling, the need for patenting, confidence in regulation, and societal values. The research findings can serve as a database that will be useful for understanding the social construct of public attitude towards GM foods in a developing country. 相似文献

Pharmaceuticals and vaccines made by genetic engineering are well accepted all over the world. In contrast, there are many people, particularly in Europe, who are worried that food, made by the same new technology, may harm their health or cause damage to the environment. This is despite the growing evidence that genetically modified crops have the potential to improve world food security and the fact that there have, as yet, been no adverse results of their use in the food chain. Because of these worries and the mechanisms of politics, agricultural biotechnology has become the target of concerns about food safety (BSE, Foot & Mouth Disease), along with globalisation and the power of multinational companies. These concerns will, hopefully, be overcome by a more open and well-informed dialogue between scientists, opinion leaders, educators and the public. If judiciously applied, genetically modified crops will help increase sustainability and the fight against hunger in the world. 相似文献
