Environmental Regulation, Market Power and Price Discrimination in the Agricultural Chemical Industry

Chemical companies generally support environmental regulatory segregation Canadian and U.S. agricultural chemical markets, apparently because it enables them to practice third order price discrimination. This study provides new cross section evidence that suggests price discrimination is practiced. We examine the potential implications chemical market desegregation for agricultural chemical prices, farmer welfare, and consumer welfare.price discrimination, agricultural chemicals, economic welfare, Environmental Economics and Policy,

Wage and Occupational Differences Between Black and White Men: Labor Market Discrimination in the Rural South

The existence of labor market discrimination based on race is well established.However, study continues into a variety of aspects of discrimination-among them the extent to which it exists in different regions. Gwartney has estimated the ratio of black to white earnings to be between .83 and .88 for the North and between .68 and .74 for the South. Masters, in a study of earnings differentials between black and white men, found a ratio of .79 for the non-South and .69 for the South. Although considerable literature has developed concerning earnings differentials, wage discrimination in rural areas is one topic which has received relatively little attention. In an attempt to eliminate this oversight this paper concentrates on the extent of wage differences between black and white men in the rural South attributable to labor market discrimination

Wert, Rechtheit and Gut. Adolf Reinach’s Contribution to Early Phenomenological Ethics

Adolf Reinach (1883-1917) is most often remembered for his role as a teacher of phenomenology or as a philosopher of law, yet the range of subjects covered in his surviving published and unpublished works is diverse. As scholars such as Kimberley Baltzer-Jaray have argued, Reinach's contributions to philosophy, and in particular his influence on the early phenomena logical movement, have been underestimated in the past. It is of both historical and philosophical importance, therefore, to identify and recognise the contributions that Reinach made across the many fields his works touch upon, including that of ethics. This thesis argues that Reinach made a number of significant contributions towards the development of early phenomenological ethics, and although his works contain neither a complete nor a comprehensive systematic theory of ethics, this is no reason to overlook or dismiss the importance of his work in this field . The thesis demonstrates that Reinach's works on ethics were original; that they influenced other early phenomenologists in the development of their ethical theories; and, ultimately, that they were and remain valuable additions to the field, discussing value-theory, the problem ofnormativity, motivation, freedom and responsibility, and more. This thesis comprises two parts. Part one examines and assesses Reinach's contribution against his immediate philosophical background incorporating a discussion of how Reinach's works on ethics fit into his body of work as well in relation to other contemporary philosophers (e.g., Brentano, Husserl, Scheler, Stein) who advanced the development of early phenomenological ethics. To support the interpretation, part two of the thesis contains appendices of three relevant extracts from Reinach 's published and unpublished works, translated for the first time into English (with original German text supplied). These translations are also intended to be ofvalue in making Reinach's works on ethics more accessible to English-speaking scholarship in the future

Cultivating Intelligent Consumption: The United States Food Administration and Food Control During World War I

This dissertation examines government food control in the United States during the First World War. More specifically, it looks at the food conservation program, and the associated propaganda, formulated by the United States Food Administration (USFA). The USFA was a wartime government agency headed by future president Herbert Hoover. I argue that the philosophy guiding the Food Administration\u27s food control program was clearly influenced by a particular strain of progressivism that men like Hoover subscribed to. Using the input of experts in various fields such as nutrition, physiology, and advertising, the government was able to present a message to the American public that both generated an emotional response to act and educated people in a new, scientific approach to eating. Such an approach allowed Hoover to avoid imposing mandatory rationing, thus preserving the freedom from government intervention into the personal lives of American citizens. In addition to examining the various dimensions of Food Administration propaganda that attempted to stir the emotions and enlighten the intelligence of the people, this dissertation also examines a third theme that is found in the messaging. Hoover and his agency also worked to get Americans to think more about how their food choices might impact people and events overseas. Through their propaganda the Food Administration sought to get people to think more globally when considering the impact of their food choices. Though the Food Administration itself was relatively short-lived, the impact it had on the shaping of modern food culture was rather large

A Pelican\u27s Journey to Flight: A Louisiana National Guardsman, The Development of the United States Army Air Service, and The Human Cost of Military Innovation

George E. Dicks deployed to the Mexican Punitive Expedition and World War I with the Louisiana National Guard. He recorded his experience in writing and photography, which reside in the Jackson Barracks Military Museum in Chalmette, Louisiana. His memorabilia reflect an officer’s perspective on early military aviation and parallel to the United States military’s experimentation with aviation. Through experimentation, Dicks became an aerial observer in World War I. This thesis explores George E. Dicks’ memorabilia and how it both represents the development of the American Air Service and the human cost of military aviation with photographic evidence. By representing aviation’s development, he illuminates the human nature of military experimentation. A comparison between Dicks and the emerging American aviator appears before an in-depth interpretation. Each photo album receives a content analysis to understand his changing perspective throughout his military career. His transition to aviation mirrors the United States’ strategy during World War I, emphasizing observational roles. Examining Dicks photo albums and journals present a unique perspective on the United States Army Air Service and the human cost of military experimentation

Development and application of a self-referencing glucose microsensor for the measurement of glucose consumption by pancreatic ?-cells

Glucose gradients generated by an artificial source and ?-cells were measured using an enzyme-based glucose microsensor, 8-?m tip diameter, as a self-referencing electrode. The technique is based on a difference measurement between two locations in a gradient and thus allows us to obtain real-time flux values with minimal impact of sensor drift or noise. Flux values were derived by incorporation of the measured differential current into Fick's first equation. In an artificial glucose gradient, a flux detection limit of 8.2 ± 0.4 pmol·cm-2·s-1 (mean ± SEM, n = 7) with a sensor sensitivity of 7.0 ± 0.4 pA/mM (mean ± SEM, n = 16) was demonstrated. Under biological conditions, the glucose sensor showed no oxygen dependence with 5 mM glucose in the bulk medium. The addition of catalase to the bulk medium was shown to ameliorate surface-dependent flux distortion close to specimens, suggesting an underlying local accumulation of hydrogen peroxide. Glucose flux from ?-cell clusters, measured in the presence of 5 mM glucose, was 61.7 ± 9.5 fmol·nL-1·s-1 (mean ± SEM, n = 9) and could be pharmacologically modulated. Glucose consumption in response to FCCP (1 ?M) transiently increased, subsequently decreasing to below basal by 93 ± 16 and 56 ± 6%, respectively (mean ± SEM, n = 5). Consumption was decreased after the application of 10 ?M rotenone by 74 ± 5% (mean ± SEM, n = 4). These results demonstrate that an enzyme-based amperometric microsensor can be applied in the self-referencing mode. Further, in obtaining glucose flux measurements from small clusters of cells, these are the first recordings of the real-time dynamic of glucose movements in a biological microenvironment. <br/

Stratospheric measurements of continuous absorption near 2400 cm^-1

Solar occultation spectra obtained with a balloon-borne interferometer have been used to study continuous absorption by N2 and CO2 near 2400 cm^-1 in the lower stratosphere. Synthetic continuum transmittances, calculated from published coefficients for far-wing absorption by CO2 lines and for pressure-induced absorption by the fundamental band of N2, are in fair agreement with the observed stratospheric values. The continuum close to the ν3 R-branch band head of CO2 is sensitive to the CO2 far-wing line shape. Therefore, given highly accurate knowledge of the N2 continuum from laboratory data, high-resolution stratospheric spectra provide a sensitive means for in situ testing of various air-broadened CO2 line shapes at low temperatures
