During the past decade, there has been growing public attention and concern over consuming products containing or processed with genetically modified organisms (GMOs). Labeling of the food products derived from the use of GMOs has thereby been a contentious debate across the world. Currently, there are two systems with regard to labeling GMO-based products: mandatory versus voluntary. The purpose of this study was to survey the research on GMOs, its application in agriculture and the surrounding labeling issues. A theoretical model was developed to analyze non-GMO producers' labeling decisions under a voluntary labeling regime, aimed at providing a theoretical perspective for governments that are contemplating the adoption of a voluntary approach to regulate GMO food products. The analysis indicates that the size of labeling costs and consumers' preferences toward non-GMO products are critical factors that will impact on non-GMO producers' labeling decisions.

"A bijection mapping that assigns natural numbers to vertices and/or edges of a graph is called a labeling. In this thesis, we consider graph labelings that have weights associated with each edge and/or vertex. If all the vertex weights (respectively, edge weights) have the same value then the labeling is called magic. If the weight is different for every vertex (respectively, every edge) then we called the labeling antimagic. In this thesis we introduce some variations of magic and antimagic labelings and discuss their properties and provide corresponding labeling schemes. There are two main parts in this thesis. One main part is on vertex labeling and the other main part is on edge labeling." / Doctor of Philosophy

This dissertation critically reviews prior labeling theory research concerning juvenile delinquency and adult criminality, and presents a structural equation model utilizing the National Longitudinal Study of Adolescent Health (Add Health). The labeling perspective is outlined as it was originally presented, and the theoretical elaborations that have taken place since are highlighted. Distinctions are made between formally applied criminal justice labels and the informal labels that are applied by significant others and parents. An interactionist labeling model that incorporates respondents’ levels of self-control is presented to explain formal labeling, levels of juvenile delinquency, and future criminality among a nationally representative sample of American adolescents: three waves of Add Health. The findings show that formal labeling was the strongest significant predictor of subsequent criminal involvement and that it mediated the effect of prior delinquency on subsequent criminal involvement.

This thesis critically reviews prior labeling theory research concerning juvenile delinquency and crime; it adds to current work by using contemporary data. Labeling events are described in detail to provide an overall understanding of where labels originate, who is casting the label, and what research suggests concerning different types of labels. An interactionist labeling model is tested to explain levels of juvenile delinquency among a nationally representative sample of American adolescents: the first three waves of the National Longitudinal Study of Adolescent Health (Add Health). Finally, negative binomial regression models are estimated in order to better explain the dynamic relationship between labels and delinquency.

What is in our food? What can food labels tell us about what is in our food? This dissertation applies rhetoric in the everyday human act of reading food labels and making decisions about what to eat based on those labels. Rhetoric is continually operating from the beginning of the food manufacturing process, to designing and writing food labels and packaging, and finally to the consumer reading the label in the store. “Natural flavors” is an ingredient listing that appears more frequently on food labels, especially in the organic and natural foods industries. I collected food labels and used qualitative methods as I rendered labels textually into Word documents in order to see the discursive elements of food labels away from the sometimes elaborate graphic design. I found that food labels contained three elements: the story, the reality, and the credibility. The story of the food label lures the consumer into an emotional response in either purchasing the food item or putting it back on the shelf. The reality of the label is in the ingredients list, or what is actually in that food item. The credibility is the availability of the manufacture in connecting with the consumer and to what extent they have transparency. By comparing these three elements on a textual page, we can see if there is truth and label equivalence between them, with “natural flavors” as a central component when it appears in the ingredients list. To the extent that there is or is not equivalence is explored through qualitative rhetorical analysis and briefly discussed by engaging Brummett’s rhetorical homologies.

Provision of appropriate information in a suitable form is therefore crucial. The package insert (PI) is the document that ensures the safe and effective use of the medicine under most circumstances. It presents a scientific, objective account of the medicine’s use as established by pre-clinical, clinical and often post-marketing studies. The patient information leaflet (PIL), which contains information for the consumer should be less scientific. South African legislation states that information contained in PILs must be aligned to PIs but the text must be readily intelligible for the patient. The study included a detailed comparison of prescribing information contained in the PI compared to the PIL in selected Angiotensin Receptor Blockers (ARBs). Findings of this comparative analysis revealed that key safety information was omitted from the PILs. An evaluation of the readability of the PILs was also performed by the use of Fry’s readability formula as well as applying elements of critical discourse analysis to determine if the texts in the PILs are suitable for its purpose. The results of the Fry’s readability assessments of all the PILs indicated that they had exceeded the recommended grade 7 reading level, which is in line with the adult literacy rate that qualifies anyone older than 15 years with a grade 7 qualification as being literate. Findings from the critical discourse analysis of the PILs show frequent use of medical jargon, complex sentence construction as well as ambiguity and slippage in the meaning of the texts in the PILs. The texts are not patient-friendly. Overall, the findings from this study indicate an urgent need to address the poor construction of PILs, to ensure that patients receive appropriate written prescribing information. This will ultimately ensure the safe and effective use of the medicine. / KP2020
