A geochemical survey of Brazilian marginal basins using a wide selection of source rocks and oils, ranging from Lower Cretaceous to Tertiary in age, has been undertaken. The aims were to assess the palaeoenvironment of deposition of the source rocks, to correlate reservoired oils with their putative source rocks and to understand the effects of maturity on the composition and absolute concentrations of biological markers. The geochemical analyses included evaluation of organic ca~bon contents, Rock-Eval pyrolysis data, vitrinite reflectance measurements, determination of carbon isotope ratios, elemental and visual kerogen analysis, and molecular studies involving liquid and gas chromatography, qualitative and quantitative biological marker investigations using GC-MS, metastable GC-MS .and GC-MS/MS for saturated and aromatic hydrocarbons, and UV/vis spectrophotometry, probe MS and HPLC for metalloporphyrins. The metastable ion GC-MS data were evaluated using principal component analysis. Integration of the results with geological and paleontological data provides the recognition and differentiation of seven depositional regimes, namely lacustrine freshwater, lacustrine saline water, marine evaporitic, marine carbonate, marine deltaic with carbonate influence, open marine highly anoxic with a predominance of calcareous mUdstone lithology, and open marine anoxic, with predominance of siliciclastic lithology. The analyses of the oils reveal significant differences between groups which enable a correlation with putative source rocks laid down in five of the above depositional regimes: lacustrine freshwater; lacustrine saline water; marine evaporitic: marine carbonate and marine deltaic with carbonate influence. The quantitative approach used to determine the effect of thermal maturity on the composition and concentration of the biological markers shows that care must be taken in their use as maturity indicators, since source input and mineral matrix might play an important role. On the other hand, it also shows that the concentrations decrease considerably between the onset of petroleum generation and its peak. Thus, care must also be exercised when using biological marker concentration in palaeoenvironmental assessment The metalloporphyrins in a selection of organic rich sediments have also been examined. The results suggest that their distributions can be a useful auxiliary tool in the characterisation of depositional environments of petroleum source rocks. Finally, a combined geochemical and micropalaeontological study of Cenomanian to Maastrichtian pelitic sediments from the continental margin extends the occurrence of the recognised Cenomanian-Turonian and santonian "oceanic anoxic events". As an extension, the presence of such events in the Coniacian is reported. In contrast, the Campanian-Maastrichtian appears to be a time interval when deposition under oxygenated conditions produced sediments with low organic carbon contents and poor hydrocarbon source potential. In summary, biological marker characteristics of organicrich sediments can distinguish different types of depositional environments, assessment of from analysis allow oil-source rock correlations, and the the depositional environment of the source rocks only of the oils. Thus, this thesis provides a framework of biological marker characteristics which can be compared with samples from other parts of the world.

Assim, o construto envolvimento destaca-se como o principal aspecto teórico do estudo. A revisão da literatura permitiu a construção de um referencial teórico onde a proposta de Zaichkowsky (1985), que lida com a mensuração do envolvimento, foi a opção adotada. Os hábitos de consumo alimentar foram investigados a partir de um estudo conduzido nacionalmente com a supervisão da Universidade Federal de São Carlos, acrescentando-se perspectivas mercadológicas de modo a permitir um melhor relacionamento com a dimensão envolvimento do consumidor. A metodologia utilizada foi de natureza descritiva, com a aplicação de um survey junto a uma amostra não probabilística de 200 indivíduos adultos na cidade do Recife-PE. Para a análise dos dados coletados, foram utilizadas técnicas estatísticas descritivas e multivariadas, onde foi possível verificar-se a existência de três dimensões de envolvimento do consumidor relacionadas aos seus hábitos alimentares: Utilidade, Prazer e Importância. Conclui-se que, de modo geral, os entrevistados apresentam-se envolvidos com o consumo de alimentos, corroborando a função básica que estes possibilitam aos seres humanos, apesar de todas as mudanças ocorridas com a chegada deste novo século

The objective of this study was to determine the psychometric properties of an employee attitude survey as developed by an Automotive Manufacturing Organization. The employee attitude survey consist of 55 items and was completed by a total of 306 employees employed at this specific organization. An exploratory factor analysis (EFA) was performed where only one factor loading resulted out of an anticipated thirteen. The inter-correlations were empirically investigated and indicated that all the items under a specific dimension did have a lot in common with one another. An anti-image inter-correlation was performed. All of the items indicated a satisfying measure of sampling adequacy (MSA) values at .595. The overall reliability of the employee attitude survey was satisfactory. These results suggested that the employee attitude survey is a handy tool for the goal the organization wants to use it for, but it does not differentiate between the thirteen different dimensions of attitude as hoped for. / Dissertation (MCom)--University of Pretoria, 2009. / Human Resource Management / unrestricted

Scientists are extremely concerned that the Florida manatee, Trichechus manatus latirostris, does not have a sufficient population number nor reproductive rate to ensure long-term species viability. This research was done to investigate aspects of boater behavior in an effort to determine measures that might decrease boat-manatee collisions and help researchers plan intervention strategies in related areas. Initially, boat data was collected over a period of several months at a Miami waterway. Next, a detailed phone survey of boat owners was conducted. Although most boaters were found noncompliant with the speed zone, several questions from the survey showed that most valued manatees and almost half wanted them to remain listed as endangered. This is very encouraging as boater support for the manatee is possibly one of the most important indicators of manatee chances for survival. Suggestions included requiring mandatory boating classes and informing boaters of faster routes to their destinations.

The purpose of this study was to record the relationships between the reptiles and amphibians of Wise County and the ecological subdivisions of the area. Wise County was chosen because of the heterogenity of the area and because of its proximity to other counties which have been previously and similarly studied.

Biological and therapeutic agents are used in food animal production to maintain animal health and well being, prevent and treat disease, and to maintain or enhance production. Concerns about the use of pharmaceutical agents in food animal production have been raised, especially in relation to food quality and safety. This study addressed the scarcity of information concerning the quantity of pharmaceuticals being used and the reasons for their use in sheep production. Additional goals included determining the sources of information used by shepherds in making treatment decisions and evaluating the economic impact that pharmaceutical usage has on sheep production. Thirty-nine Virginia sheep producers participated in this study of four months duration from March through September. After completing an initial questionnaire to determine flock and management characteristics, participants were asked to record all treatments with biological and therapeutic agents that occurred within their sheep flocks. A total of 14,310 treatments were recorded for a median of 1.5 treatments per sheep per month. Parasite control and vaccination were the most frequent reasons for treatment (64.9% and 15.2%, respectively) with vitamin/mineral supplementation being the next most common (8.8%). Price information was collected for 13,912 treatment events. An estimated total of $7,523.78 was spent on pharmaceutical treatment over the course of the study. This amounts to a cost of $0.63 per sheep per month of observation. Results of this study will enhance the ability of producers to evaluate treatment decisions, allow comparisons to be made between operations and provide a base of information for future research. / Master of Science

In less than three hundred years, the American frontier has been advanced from the Connecticut River Valley thru the fertile prairies of the Middle West to the Pacific and the frozen tundras of Alaska. Behind the crest of this pioneer wae, homeseekers rapidly occupied the bounteous regions of our great West.
