A CONTENT ANALYSIS OF SOURCE-MESSAGE HETEROGENEITY IN MASS MEDIA COVERAGE OF AGROBIOTECHNOLOGY AgEcon
Marks, Leonie A.; Kalaitzandonakes, Nicholas G.; Zakharova, Lucy.
In this paper, we use content analysis to examine the use of sources by US and UK newspaper reporters from 1990 to 1999. Positive (benefit) or negative (risk) messages are correlated with the "source" type in order to determine the degree of source-message heterogeneity in media reporting of agrobiotechnology.

EVALUATING ALTERNATIVE FARMING SYSTEMS: A FUZZY MADM APPROACH AgEcon
Marks, Leonie A.; Dunn, Elizabeth G..
This paper develops a decision support method that integrates measures of achievement in the economic, environmental, and social aspects of farming. The decision support method combines multiple attribute decision making (MADM) with fuzzy logic. The fuzzy MADM model fully ranks decision alternatives relative to the preferences of decision makers and overcomes several problems inherent in other MADM approaches. It is concluded that fuzzy MADM can improve decision making on the farm.

Evaluating Consumer Response to GM Foods: Some Methodological Considerations AgEcon
Marks, Leonie A.; Kalaitzandonakes, Nicholas G.; Vickner, Steven S..
In 1998 the European Union placed a moratorium on the planting of transgenic crops within its borders. The resulting ban on biotech crops has led to the current trans-Atlantic trade dispute between the United States and the EU. At the heart of this dispute is the issue of consumer acceptance. The EU’s current position is predicated on perceived public concerns about biotech foods which found a voice in numerous opinion polls conducted during the late 1990s (e.g., European Commission, 1997, 2000). Such concerns have also been amplified by intense media coverage and resulting political activism. Given the pivotal role that consumer opinion has played in recent EU policy, an understanding of how consumers value biotech foods is critical to informed...

FOOD PRODUCT RECALLS, AGBIOTECH AND CONSUMER RESPONSE: THE CASE OF STARLINK AgEcon
Vickner, Steven S.; Marks, Leonie A.; Kalaitzandonakes, Nicholas G..
Using a conditional nonlinear AIDS model and three years of syndicated, national-level weekly point-of-purchase scanner data, we empirically estimate the consumer response to the Starlink recall while controlling for relative prices, per capita real expenditure, holidays, post-recall demand trends and the media. In the salted snacks product category, acute media coverage reduced the expenditure share for the recalled products and those shares nearly recovered 12 months post-recall. Expenditure shares in the chili seasonings product category were unaffected by the recall and media coverage.

MARKETING OF BIOTECH FUNCTIONAL FOODS IN THE US AgEcon
Chema, Kambua; Marks, Leonie A.; Parcell, Joseph L.; Bredahl, Maury E..
To date, most research in Europe and the United States has focused on eliciting consumer WTP for biotech foods without directly addressing strategies for marketing them. We use means-end theory to link consumers' knowledge about functional attributes, to their knowledge about consequences and core values, in order to gain insights into valued attributes for developing potential marketing strategies.

MEDIA COVERAGE OF AGROBIOTECHNOLOGY: DID THE BUTTERFLY HAVE AN EFFECT? AgEcon
Marks, Leonie A.; Kalaitzandonakes, Nicholas G.; Allison, Kevin; Zakharova, Ludmila.
This study examines media coverage of genetically modified (GM) crops in a risk communication framework. Content analysis is employed to investigate how specific environmental, food safety, and landmark events, such as the monarch butterfly and Pusztai controversies, and the cloning of Dolly-the-sheep, were reported by the media. Media coverage is from United Kingdom and United States newspapers over the period 1990 through 2001. On balance, findings show that the UK press has been more negative than the U.S. press in its coverage of GM crops. In addition, environmental and food safety events had a significant impact on the level and cycle of GM crop coverage.

PUBLIC OPINION OF AGBIOTECH IN THE US AND UK: A CONTENT ANALYSIS APPROACH AgEcon
Kalaitzandonakes, Nicholas G.; Marks, Leonie A..
In this paper we use content analysis to show trend in public opinion of agrobiotechnology in the United Kingdom (UK) and the United States (US). We test for the degree of positive and negative content in mass media reporting over the period 1995-1998. Specifically, we test whether there are qualitative and quantitative differences between three national daily newspapers - the Daily Telegraph (UK), USA Today (US), and the Washington Post (US) - based on reporting of agrobiotechnology. Results indicate that content has become more negative in the UK over the time period while reporting the US has not significantly changed. Results indicate that both the BSE and Pusztai crises had an impact on the proportion of negative reporting in the Daily Telegraph.

Trust in Biotechnology Risk Managers: Insights from the United Kingdom, 1996-2002 AgEcon
James, Harvey S., Jr.; Marks, Leonie A..
During the late 1990s a series of negative events occurred in the United Kingdom (UK) related to biotechnology. These events signaled potential risks associated with biotech foods and crops and were highly reported. According to the trust asymmetry hypothesis, such events ought to cause public trust in risk managers of biotechnology to decline rapidly and rebound more slowly. We find, based on data taken from the Eurobarometer surveys conducted in 1996, 1999 and 2002, that public trust in risk managers did decline from 1996 to 1999. However, the level of trust rebounded sharply between 1999 and 2002. Canonical discriminant analysis of public trust is used to reveal possible explanatory factors in this response. We find that whether people trust or distrust...

Trust in Biotechnology Risk Managers: Insights from the United Kingdom, 1996-2002 AgEcon
James, Harvey S., Jr.; Marks, Leonie A..
The mid to late 1990s saw a series of negative media events in the United Kingdom (UK) related to biotechnology. According to the trust asymmetry hypothesis, such events ought to cause public trust in risk managers of biotechnology to fall quickly but rise slowly. We present evidence from the Eurobarometer surveys that from 1996 to 1999 public trust in the UK declined, but it increased sharply between 1999 and 2002. We seek to explain this apparent contradiction to the asymmetry hypothesis. We use canonical discriminant analysis of public trust to show that whether people trust or distrust risk managers of biotechnology depends significantly on the amount of knowledge people have about science. We speculate that knowledge of science moderates the trust...
