Macroinvertebrates constitute the backbone of megafaunal communities in benthic ecosystems around the globe. Many macroinvertebrates have vital roles in benthic ecosystems, ranging from enhancing habitat complexity to providing staple food sources for other organisms. Regardless of how familiar macroinvertebrates are to the general public, very few studies have attempted to describe benthic macroinvertebrate assemblages across large spatial scale in the continental shelf waters of the Pacific Northwest. This study describes different subtidal macroinvertebrate assemblages off Washington and Oregon based on species-substrata associations and the key species that distinguish one assemblage from another. Two data sets were used for this study: underwater footage collected by the submersible Delta during 1993-1995 geological surveys, and footage collected by the remotely operated vehicle (ROV) Hammerhead during macroinvertebrate surveys in late summer 2011. Footages from these surveys were used to document species-substrata associations and distinguish different assemblages based on species composition similarities and dissimilarities. In addition, I determined if a specific group of invertebrates, Asteroids (Echinodermata), were useful in explaining different assemblage patterns, after all other environmental parameters were taken into account. Findings of this study can be used not only to shed light on the structure of macroinvertebrate communities in the Pacific Northwest, but also as baseline data for future research on the direct and indirect effects of potential offshore installations on macroinvertebrate communities across the continental shelf waters. / Graduation date: 2012

Decision making for fast-moving consumer goods involves a choice between numerous similar alternatives. Under such demanding circumstances, a decision is made for one product. The decision is dependent on the interaction between the environment and the mind of the consumer, both of which are filled with information that can influence the outcome. The aim of this dissertation is to explore how the mind and the environment guides attention towards considered and chosen products in consumer decision making at the point-of-purchase. Consumers are equipped with several effort reduction strategies to simplify complex decision making. The selection of strategies can be conscious or automatic and driven by information in the environment or the mind of the decision maker. The selected decision strategy reduces the set of options to one alternative in an iterative process of comparisons that are fast and rely on perceptual cues to quickly exclude irrelevant products. This thesis uses eye-tracking to explore this rapid processing that lacks conscious access or control. The purpose is to explore how product packaging and placement (as in-store factors), and recognition, preferences, and choice task (as out-of-store factors) influence the decision-making process through visual attention. The results of the 10 experiments in the five papers that comprise this thesis shed new light on the role of visual attention in the interaction between the environment and the mind, and its influence on the consumer. It is said that consumers choose with their eyes, which means that unseen is unsold. The results of this thesis show that it is just as important to be comprehended as it is to be seen. In split-second decision making, the ability to recognize and comprehend a product can significantly impact preferences. Comprehension stretches beyond perception as consumers infer value from memory structures that influence attention. Hence, the eye truly sees what the mind is prepared to comprehend.

Service quality has always been a tacit assumption within the delivery of academic library services, but since the 1990s demands for accountability from different stakeholders, including the clients, made service quality a highly debated and researched focus in academic libraries all over the world. The scope of the study covers a wide-ranging analysis of discourses underpinning service quality and its accompanying performance indicators in academic libraries. Using the academic library of the University of South Africa as an illustrative case study, this study examines the possible impact of inventory control on the service quality of the academic library in three areas, namely access to information resources, retrieval of information resources and positive implications for sound financial management. The study's findings all point to a positive enhancement of service quality in regard to the three areas mentioned. / Information Science / M. Inf.

Cowpea (Vigna unguiculata) and moringa (Moringa oleifera) are nutritious and medicinal vegetables, but could also harbor harmful microbial contaminants. The main aim of the project was to determine the effect of each processing techniques on the microbiology, proximate nutrients and shelf life of these vegetables to produce nutritious, tasty, safe and long lasting vegetable products. The processing techniques used were: washing, blanching, and drying. Leaf samples were collected at each stage of processing and were analysed for total viable count, coliform count, yeast and mould count and nutritional content. Microbial plate analysis showed the presence, particularly on cowpea leaves, of yeasts and bacteria such as Pseudomonas, Klebsiella, Staphylococci, Streptococci, and enterobacter including enteropathogens such as Salmonella spp., Shigella dysenteriae and E coli. The presence of E.coli on the leaves was also confirmed using polymerase chain reaction-amplified ribosomal DNA analysis. The most effective processing technique which reduced microbial load to below SABS standards while retaining nutritional quality was the washing of the leaves twice with tap water followed by steam tunnel blanching at 94oC for 12 minutes. Oven drying the leaves at 60oC gave satisfactory and extended shelf life results. Proximate analysis comparison of the two leaf types showed that on average moringa leaves contained more ash (2.37 vs 1.1 g), protein (6,9 vs 3,6 g), fat (0,41 vs 0.2 g) and energy (305,1 vs 70KJ) but less dietary fibre (0,9 vs 7,5 g) than cowpea leaves. No significant differences were noted in these values following washing and steam blanching. These results indicate that washing of these leaves is effective as to reducing microbial load and maintaining proximate values in the short term (up to 4 days) but that oven drying is effective for longer-term storage. / Life and Consumer Sciences / M.

A diversidade do uso do espaço oceânico e a antiga concepção da “doutrina da liberdade dos mares” forçou uma readequação do ordenamento político-econômico e espacial do ecossistema oceânico. Este redirecionamento, que envolveu o sistema internacional, originou uma nova geopolítica ou uma nova ordem global para o planejamento espacial oceânico, nos termos da Convenção das Nações Unidas sobre o Direito do Mar (CNUDM). Em razão de tais alterações, contextualizar-se-á a história do mar territorial brasileiro, em 1970, e suas implicações políticas nacionais e internacionais. Após, serão averiguadas as coalizões integradas pelo Brasil em uma aparente “batalha diplomática”, que se estendeu além de nove anos, envolveu mais de 130 países e originou um dos tratados mais bem sucedidos da história: a Convenção das Nações Unidas sobre o Direito do Mar. A partir de então, dentre outras conquistas, os Estados Partes garantiram o seu direito legal ao solo e subsolo marinho, mediante submissões para a plataforma continental além das 200 milhas náuticas, definidos no artigo 76 da Convenção. Tal conquista possibilitou aos países em desenvolvimento e a pequenas nações insulares acesso a valiosos recursos naturais, como o petróleo, gás e minerais. Os Estados costeiros, signatários da Convenção, passaram a ter assegurado o direito de reivindicar seu território submerso, ou a plataforma continental estendida, para até 350 milhas náuticas. Com a nova regulamentação, a análise das submissões passou a ser feita pela Comissão de Limites da Plataforma Continental (CLPC), organismo derivado da CNUDM, onde especialistas, selecionados segundo o critério de equidade geográfica, aceitam, modificam ou rejeitam as reivindicações. Demonstrar-se-á procedimentos adotados por Estados costeiros (insulares ou arquipelágicos) ao solicitar a ampliação de seus limites oceânicos, o modo dos especialistas brasileiros trabalharem a ampliação da plataforma continental estendida e de que forma foi feito o planejamento e o gerenciamento em termos políticos, através da Comissão Interministerial para os Recursos do Mar. Finalmente, averiguar-se-á se o Governo do Brasil terá condições de assumir tal responsabilidade, considerando o possível aumento de suas fronteiras e a capacidade do Estado, em termos científicos, tecnológicos e políticos, de internalizar e cumprir os preceitos da Convenção em sua política nacional para o mar. / The diversity of uses of the oceanic space and the old conception of “freedom of the seas doctrine” has compelled an adaptation of the political-economic and spatial legal framework for the oceanic ecosystem. This changing of direction encompassed the international system and has given rise to a new geopolitics for the legal framework of oceanic spaces around the globe, in terms of the United Nations Convention on the Law of the Sea (UNCLOS). Because of such modifications, this study contextualizes the history of Brazilian territorial sea in 1970 and its political implications, on the national as well as on the international level. After that, it examines the alliances Brazil has formed, engaging in a so called “diplomatic battle”. This process went on for over nine years, comprised more than 130 countries and originated one of the most successful treaties in history: the United Nations Convention on the Law of the Sea. Since then, the signatory states managed to secure their legal rights over the maritime soil and subsoil by means of submissions for the continental shelf beyond 200 nautical miles, as defined by the Convention in its article 76. This achievement was of utmost importance because it enabled developing countries and small island states to access valuable natural resources such as oil, gas and minerals. Every coastal state who has signed the Convention acquired the right to claim its underwater territory or extended continental shelf up to 350 nautical miles from its coast. Due to the new regulations, the Commission on the Limits of the Continental Shelf (CLCS) began to undertake the analysis of submissions. This Commission is a body set up by the UNCLOS, in which experts, selected according to the criterion of geographic equity will accept, modify or reject claims. Furthermore, this study aims to account for procedures taken by coastal, insular, and archipelagic states when claiming the extension of its oceanic limits, with the main focus on measures taken by Brazil. More specifically, it intends to explain how Brazilian experts have brought about the expansion of the extended continental shelf and in which way planning and management, in political terms, can be carried out through the Interministerial Commission for Maritime Resources. Ultimately, it will be examined if the Brazilian government is able to assume such responsibility in the face of the growth of its borders and the capability of the state, in scientific, technological and political terms, of incorporating and enforcing the precepts of the Convention in its national policy for the seas.

Concentrations of these parameters measured in situ were compared in time quasi-synchronous with images AQUA-MODIS between the years 2003 to 2011. Determination coefficients between samples in situ and bands reflectance sensor AQUA-MODIS were representative. From that, concentrations of SSL parameters were acquired for the continental shelf of the RN (eastern and northern) analyzing the geographic distribution of variation of these parameters between the years 2009-2012. Geographical and seasonal variations mainly influenced by global climate phenomena such as El Ni?o and La Ni?a, were found through the analysis of AQUA-MODIS images by Principal Components Analysis (PCA). Images show qualitatively the variance and availability of TSM in the regions, as well as their relationship with coastal erosion hotspots, monitored along the coast of the RN. In one of the areas identified as being of limited availability of TSM, we developed a methodology for assessment and evaluation of Digital Elevation Models (DEM) of beach surfaces (emerged and submerged sections) from the integration of topographic and bathymetric data measured in situ and accurately georeferenced compatible to studies of geomorphology and coastal dynamics of short duration. The methodology consisted of surveys with GNSS positioning operated in cinematic relative mode involved in topographic and bathymetric executed in relation to the stations of the geodetic network of the study area, which provided geodetic link to the Brazilian Geodetic System (GBS), univocal , fixed, and relatively stable over time. In this study Ponta Negra Beach, Natal / RN, was identified as a region with low variance and availability of MPS in the region off, as characterized by intense human occupation and intense coastal erosion in recent decades, which presents potential of the proposed methodology for accuracy and productivity, and the progress achieved in relation to the classical methods of surveying beach profiles / Este trabalho apresenta modelos de par?metros da Camada Superficial do Mar (CSM), tais como: Clorofila-a, Temperatura da Superf?cie do Mar (TSM), Produtividade Prim?ria (PP) e Material Particulado em Suspen??o (MPS), para a regi?o adjacente a plataforma continental do Rio Grande do Norte (RN), Brasil. Concentra??es desses par?metros medidos in situ foram comparadas em tempo quase-s?ncronos com imagens AQUAMODIS entre os anos de 2003 at? 2011. Coeficientes de determina??o foram representativos entre as amostras in situ e as bandas de reflect?ncia do sensor AQUAMODIS. A partir disso, concentra??es de par?metros da CSM foram adquiridos para a plataforma continental do RN (Plataforma Oriental e Setentrional) analisando a distribui??o geogr?fica da varia??o desses par?metros entre os anos de 2009-2012. Varia??es geogr?ficas e sazonais influenciadas principalmente por fen?menos clim?ticos globais como o fen?meno El Ni?o e La Ni?a, foram constatadas atrav?s das an?lises das imagens AQUA-MODIS por an?lise de Principais Componentes (PC). As imagens apontam de maneira qualitativa a vari?ncia e disponibilidade do MPS nas regi?es, assim como sua rela??o com hotspots de eros?o costeira, monitorados ao longo do litoral do RN. Em uma das regi?es identificadas como sendo de pouca disponibilidade de MPS, foi desenvolvida uma metodologia para levantamento e avalia??o de Modelos Digitais de Eleva??o (MDE) de superf?cies praiais (setores emersos e submersos) a partir da integra??o de dados topogr?ficos e batim?tricos mensurados in situ e georreferenciados com precis?o compat?vel aos estudos de geomorfologia e din?mica costeira de curta dura??o. A metodologia desenvolvida consistiu de levantamentos com posicionamentos GNSS operados no modo relativo cinem?tico envolvidos nos levantamentos topogr?ficos e batim?tricos executados em rela??o ?s esta??es da rede geod?sica da ?rea de estudo, que forneceram referencial geod?sico vinculado ao Sistema Geod?sico Brasileiro (SGB), o qual ? un?voco, fixo e relativamente est?vel no tempo. No estudo foi apresentado a Praia de Ponta Negra, Natal/RN, identificada como uma regi?o com baixa vari?ncia e disponibilidade de MPS ao largo, assim como, caracterizada por intensa ocupa??o antr?pica e intensa eros?o costeira nas ?ltimas d?cadas, no qual s?o apresentadas as potencialidades da metodologia proposta, quanto ? acur?cia e produtividade, al?m dos avan?os alcan?ados em rela??o aos m?todos cl?ssicos de levantamento de perfis de praia
