Documenting Food Safety Claims and Their Influence on Product Prices
Get PDFIn response to increasing customer attention to food attributes, agribusinesses are employing novel product differentiation strategies. As an example, we investigate the use of food safety claims on new packaged food products from the food manufacturers’ perspective. First, using two product innovation databases, we investigate claim use on labels in seven English-speaking countries over the period from 1980 to 2008. Then, based on manufacturer recommended selling prices and using U.S. data (from 2002 to 2008), we apply parametric and nonparametric hedonic methods to identify supply-side (agribusiness) valuations of chemical and microbiological claims in two food categories. We identify a significant 5 cent premium per ounce for a “preservative free†claim in spoonable yogurts. We do not find a statistically significant impact for “E. coli free†messages on meat and poultry products but find a significant price premium (19.3 cents and 25.7 cents per ounce in the two models) for “antibiotic free†claims in this category.food safety claims, parametric and nonparametric hedonic models, price premium, Marketing,
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Consumers and food recalls: what does the public want to hear?
No full textIntroduction: Motivating people to appropriately respond to a food recall can be extremely difficult.
Purpose: The purpose of this study was to identify public perceptions of food safety and food recalls, and to determine what messages will encourage the public to perform desired responses to recalls such as checking their homes for the recalled product.
Methods: A survey research firm was hired to conduct a national, random-digit dial telephone survey of 1,101 Americans in all 50 states. Data were collected during August and September, 2008.
Results: The findings indicate that 80% of Americans believe that food recalls are becoming more frequent, though far fewer believe that the number of recalls increased between 2006 and 2007. Knowledge about the mechanisms of the food recall system is quite low (e.g., 73% believe that the Food and Drug Administration is responsible for recalls of meat and poultry). More than half of Americans (59%) report having looked in their home for recalled foods at least once, and 35% of these report having found some. When asked to rate the types of information that are most important for the media to include in stories about food recalls, the illnesses and symptoms caused by eating the recalled product and whether anyone has become ill from eating the product were rated as the most important. Similarly, respondents said that knowing how many people had been made ill by a food recall would be most likely to motivate them to check their homes for a recalled food product.
Significance: Taken together, the findings indicate that before paying attention to any of the more detailed information about food recalls, Americans want to determine whether a food recall applies to them (and the food they eat) and the severity of the problem.Poster presented July 13, 2009 at the 96th annual meeting of the International Association for Food Protection, Grapevine, TexasPeer reviewe
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Transporting Fresh Fruits and Vegetables: What is the Role of the the Public Sector?
No full textTransportation of nutritious and affordable food can create both challenges and opportunities for American households. Increasing the availability and consumption of fresh fruits and vegetables is a public health goal for physical health, mental health, financial stability, and other benefits. This raises the question of the public sector’s role in influencing the transportation of nutritious and affordable food. In particular, how can policy help to expand the fresh fruit and vegetable market by influencing distribution. This thesis examines the domestic refrigerated trucking industry and the movement of fresh produce. Based upon available data, this study uses four specialty crops, kale greens, apples, collard greens, and carrots as example commodities, due to their cultural, economic and nutritional significance. The datasets are from the United States Department of Agriculture (USDA) Agriculture Marketing Service (AMS). Each commodity reports truck and shipping movement, shipping points, terminal markets, and retail markets. Using multivariate regressions, this data (2010 to 2023) is examined to better understand effects on quantity shipped and the various prices discovered through these supply chains.
Based upon the results, several questions can be answered, such as origins with the highest price and how those correlate to quantity; how the shipping point versus shipping movement prices effect quantity; and what retail markets have the most stores promoting produce. Based upon these answers, broader questions relating to, comparative advantage, consumer preferences, where market imperfections exist, and economic, environmental, and societal sustainability can be addressed. The findings from these questions can help contribute to further inquiry of the public sector’s role in facilitating the transportation of nutritious and affordable food.No embargoAcademic Major: Public Policy Analysi
Beyond the B: Examining B Corp Certification's Depth and Breadth
Get PDFThis research investigates the role of B Corp certification in shaping and supporting sustainability signaling. Corporate Social Responsibility (CSR) and Environmental, Social, and Governance (ESG) frameworks are becoming increasingly central to market self-regulation. Systems like B Corp, covering more than 9,000 firms, offer structured, voluntary methods for evaluating business impact. However, concerns remain about the reliability of scoring systems and the extent to which the information they generate meaningfully reaches consumers and other stakeholders.
This research draws from public policy, business ethics, and data analysis to conduct a dual inquiry into the internal consistency of B Corp’s metrics and the external flow of its sustainability messaging by focusing on the cohort of certified firms. Methodologically, the inquiry combines quantitative analysis and exploration of B Lab’s self-published B Impact score data with qualitative content analysis of firm-level communications. The latter employs a micro-meso-macro framework to examine how B Corp information is presented by twenty leading firms across distinct communication levels: product packaging, firm websites and CSR reports, and B Lab’s member directory. These efforts offer insights for policymakers evaluating the strengths and limitations of private sustainability certifications as tools for public-private governance and future ESG policy development.No embargoAcademic Major: Public Policy Analysi
A Regional-level Comparison of the Cost of Food Safety Failures
Get PDFFood safety failures can have dramatic effects on public health triggering policy interventions. Once policy is in place, the effectiveness of control should be monitored. Two major outcomes of food safety failures - outbreaks and recalls – are often used as proxies of control in food safety economics research. Due to data limitations, or because of a particular policy focus, most studies of the effectiveness of food safety controls have been conducted at a national level. It is unclear what regional or state differences may be lost in this aggregation. As one common metric of the economic impact of food safety failures on consumers, Kuchler and Golan (1999) discuss the cost of illness (COI) approach, which will be employed in this research. COI calculates the consumer burden which is a lower bound of the cost of food safety failures. Other elements of the burden to society include government and firm costs. This poster compares such disaggregated cost elements to inform policy evaluations. The information contained in recall and outbreak databases at a regional level will be compared and linked to covariates to highlight patterns of policy effectiveness. Preliminary results suggest similar patterns of food safety failure costs are indicated using both sets of information in many portions of the US. However, in other regions the two forms of food safety failures lead to very different estimates of the cost burden, suggesting the need to impose weights in policy effectiveness studies
