Consumer Power To Change The Food System? A Critical Reading Of Food Labels As Governance Spaces: The Case Of Acai Berry Superfoods, Christine Parker, Hope Johnson, Janine Curll

Journal of Food Law & Policy

This article argues that the marketing claims on food labels are a governance space worthy of critical examination. We use a case study of superfood açaí berry products to illustrate how marketing claims on food labels encapsulate dominant neoliberal constructions of global food systems. These marketing claims implicitly promise that by making careful choices consumers can resist and redress the ravages of unbridled global capitalism. Food labels suggest that consumers can use market signals to simultaneously govern our own selves and the market to ensure sustainable, fair, and healthy consumption. In response, this article develops, justifies and applies a socio-legal …

Federal Regulation Of Pesticide Residues: A Brief History And Analysis, Kate Z. Graham

Journal of Food Law & Policy

In the United States today, there are over 900 pesticides in use1 and over 400 are approved for use in food production, whether used as part of the growing process or in post-harvest handling. Although the history of pesticide use in food crops goes back centuries, the post-war period has seen an enormous growth in the varieties and amounts of pesticides used in our food system. As our reliance on pesticides has grown, pesticides have become a divisive issue. Pesticide advocates view them as essential to a secure and reliable food supply needed to feed a growing world population. Detractors, …

Evaluation Of Herd Size Management Strategies, Colson A. Tester

Graduate Theses and Dissertations

This thesis is comprised of two studies examining the effects of price signal based herd size management strategies on profitability of cow-calf operations. Herd size management strategies were evaluated across the previous two cattle cycles, 1990-2014, using a fixed land resource and included a variety of production scenarios. These scenarios varied in terms of stocking rates, fertilizer applications rates, and calving season. Each scenario was also analyzed both with and without weather effects on forage production. Weather effects were simulated using a production index derived from satellite imagery across the observed 25-year period. Three herd size management strategies: i) constant …

Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren

Graduate Theses and Dissertations

According to USDA FAS, in 2017, the US was the largest broiler-producing country with 18.696 million metric tons and the second largest exporter of broiler products with 3.075 million metric tons (Brazil is the largest exporter with 3.847 million metric tons). Thus, around 83% of US production is consumed domestically. According to USITC, chickens are the most important protein source in the US, and Americans consume more chicken per capita than any other country. However, while the broiler industry is a key segment of US agriculture, it is underserved by large-scale supply-chain and trade models.

The Effect Of Osmotic Stimulation Of Copeptin On Glucose Metabolism In Healthy Adults, Lisa Tjorven Jansen

Graduate Theses and Dissertations

Diabetes is currently affecting 30 million Americans. To combat disease onset, lifestyle interventions have been focused on. Low water intake, alongside elevated concentrations of circulating copeptin, has been linked to increased risk for. However, it is unknown whether this effect on glucose regulation is acute or chronic. Furthermore, no study to date assessed the effects of copeptin independent of the renin-angiotensin-aldosterone system (RAAS). Purpose: The purpose of these studies was therefore two-fold: 1) to establish high endogenous copeptin concentrations independent of RAAS, and 2) to assess glucose metabolism following a standardized oral glucose tolerance test (OGTT) during high concentrations of …

Energy Content Of Seeds Of Texas Doveweed (Croton Texensis) From The Diet Of Mourning Doves (Zenaida Macroura) From Southeastern New Mexico, John L. Hunt, Matthew E. Grilliot, Troy L. Best, Collin S. Deen, Dixie Lozano-Lopez, Emily R. Neilson, Taytumn R. Schlegel-Ridgway

Journal of the Arkansas Academy of Science

We analyzed the energy content of seeds of Texas doveweed (Croton texensis) obtained from the crops of mourning doves (Zenaida macroura) collected from plains-mesa sand-scrub habitat in Eddy and Lea counties, New Mexico. Seeds were removed from crops and dried for 48 hours at 60°C to remove moisture and to standardize masses. Seeds were then analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of seeds of Texas doveweed was greater than many seeds previously reported from the diet of mourning doves.
