The author argues that beyond religious beliefs and conservative politics, rhetorical identification played an important role in the relative calmness of the BYU campus during the turbulent Sixties. Using Bitzer's rhetorical situation theory and Burke's identification theory, the author shows that BYU's calm campus can be explained as a result of communal identification with a conservative ethos. He also shows that apparent epistemological shortcomings of Bitzer's model can be resolved by considering the power of identification to create salience and knowledge in rhetorical situations. During the Sixties, BYU administration developed policies on physical appearance that invited students to take on a conservative identity, and therefore a conservative behavior. Relationships of power and hierarchy at BYU can be understood not as quantitative and oppressive matrices, but as rhetorical choices of students to identify with the character of school president, Ernest Wilkinson, and the administration. Power, then, is as Foucault envisioned it—as a field wherein identity and discourse are negotiated. This thesis argues for a more broad understanding of identification, ethos, and power for explaining rhetorical behavior in communal situations.

Cette thèse étudie la représentation de l’accueil et de la réinsertion des vétérans du Viêt-nam dans deux quotidiens américains de qualité, le New York Times et le Washington Post, de 1966 à 1978. La comparaison entre les deux journaux est complétée par les analyses de deux hebdomadaires, The Nation et Newsweek, et d’un bimensuel, la National Review, qui balayent toute la gamme des points de vue sur le sujet. Deux périodes peuvent être distinguées : de 1966 à 1970, la réintégration des anciens combattants semble être facile, selon les publications. De 1971 à 1978, la couverture médiatique s’intensifie dans un premier temps, du fait des difficultés de réinsertion que les Vietvets rencontrent et osent enfin exprimer avec force ; la presse paraît ensuite se désintéresser progressivement d’eux. L’évolution, dans les journaux, de la représentation des vétérans et de leur réinsertion reflète l’évolution de la société et de l’économie américaines. Si les deux quotidiens s’adressent, a priori, à des lectorats voisins, les réalités qu’ils choisissent de montrer, en les déformant suivant leur biais idéologique, divergent souvent. Il s’agit également de voir dans quelle mesure leurs représentations ont pu aider la réinsertion des anciens combattants ou, au contraire, la rendre plus délicate. / This thesis studies the reception and the reintegration in society of Vietnam war veterans as they are represented in two American dailies, The New York Times and The Washington Post. To this comparison between the two newspapers are added the analyses of two weeklies, The Nation and Newsweek, and a bimonthly, National Review, which provide a complete range of the various point of views on the subject. Two periods stand out: from 1966 to 1970, the reintegration of the former soldiers seemed to be easy, according to the newspapers. From 1971 to 1978, the coverage by the media first intensified owing to the difficulties of reintegration that the Vietvets faced and dared to voice loudly for the first time; the press then appeared to progressively lose interest in them. The evolution, in the newpapers, of the representation of the veterans and of their reintegration mirrored the evolution of American society and economy. If both dailies a priori addressed the same kind of readers, the reality that they chose to present and distort through their ideological bias often differed. The thesis also tries to show how their representations may have helped or hindered the reintegration of Vietvets in society.

The tragic and devastating September 11 attacks resulted in a variety of original musical responses. Exemplary works expressed their reactions through overt 9/11-concentric dialogues to express themes of mourning, military retribution, dissent and commemoration. An examination of such works concludes that effective musical responses express a direct message clarified by supporting musical and/or textual materials. Musical materials can accentuate the specific thematic message of the responsive work as they often evoke images and emotions reminiscent of the attacks and their aftermath. Compositional techniques used in these works are often reminiscent of historical works written in similar circumstances. The recurrence of these historical approaches illuminates the timeless compositional design of historical examples and exemplifies modern advancements in music composition and production. A comparison between classical and popular post-9/11 musical compositions concludes that certain classical and popular genres deal with responsive themes more effectively than others. A recommendation for further study is enclosed.

Although arsenic is naturally present in the environment, 99% of human exposure to arsenic is through ingestion. Throughout history, arsenic is known as “the king of poisons”; it is mutagenic, carcinogenic, and teratogenic. Even in smaller concentrations, it accumulates in the body and takes decades before any physical symptoms of arsenic poisoning shows. According to the World Health Organization (WHO), the safe concentration of arsenic in drinking water is 10 µg/L. However, this limit is often times ignored until it is decades too late and people begin showing symptoms of having been poisoned. This is the current situation for Vietnam, whose legal arsenic concentration limit is 50 µg/L, five times higher than the WHO guidelines. Groundwater in Vietnam was already naturally high in arsenic due to arsenic-rich soils releasing arsenic into groundwater. Then, in the past half century, with the use of arsenic-laden herbicides dispersed during the Vietnam War and subsequent industrial developments, the levels of bio-available arsenicals has dangerously spiked. With the proliferation of government-subsidized shallow tube-wells in the past two decades, shallow groundwater has become the primary source for drinking and irrigation water in Vietnam. This is a frightening trend, because this groundwater has arsenic concentrations up to 3050 µg/L, primarily in the +3 and +5 oxidation states, the most readily available oxidation states for bioaccumulation. This thesis argues that measures must be taken immediately to remedy the high concentration of arsenic in groundwater, which in Vietnam is the primary and, in some cases, the sole source of water for domestic consumption and agricultural production. Although there are numerous technologies available for treating arsenic in groundwater, not all of them are suited for Vietnam. By analyzing the historical, cultural, economic, and political parameters of Vietnam, several optimal treatments of groundwater for drinking water emerged as most recommended, a classification that is based on their local suitability, social acceptability, financial feasibility, and governmental support. Further research on irrigation water treatment is proposed due to the need for sustainable crop production, the safe ingestion of rice and vegetables, and the continued growth of Vietnam’s economy, which is heavily dependent on agriculture.
