Esse ambiente é afetado pelo aporte continental, atuando como um receptor final de água, materiais e substâncias, que são transportados pelas descargas dos rios. Desta forma, as regiões costeiras são as mais afetadas pela ação antrópica. O presente trabalho apresentou como objetivo analisar a dinâmica da clorofila-a e parâmetros hidrológicos na plataforma continental de Pernambuco adjacente aos rios Jaboatão e Capibaribe. Foram realizadas coletas bimestrais, abrangendo período chuvoso e de estiagem, em um ponto situado na zona estuarina e quatro outros pontos distribuídos na plataforma. Foram analisados vários parâmetros ambientais como clorofila a, profundidade, salinidade, temperatura, oxigênio dissolvido, taxa de saturação do oxigênio, pH, nutrientes inorgânicos (N- amoniacal, nitrito, nitrato, fosfato e silicato), material particulado em suspensão. A pluviosidade foi a forçante física que mais influenciou na maioria dos parâmetros. No rio Jaboatão, a clorofila-a no estuário variou de 2,89 à 34,71 mg.m-3 e na plataforma de 0,21 à 9,67 mg.m-3 . De acordo com a ACP, a clorofila a esteve diretamente relacionada temperatura, taxa de saturação do oxigênio e inversamente com o pH, transparência da água e salinidade. No porto do Recife, a clorofila a variou entre 13,48 à 145,09 mg.m-3 no estuário e na plataforma a de 0,24 à 19,29 mg.m-3 . A ACP mostrou uma relação direta da clorofila-a com o N-amoniacal, fosfato, transparência e inversa com nitrato e material particulado em suspensão. Nas duas áreas estudadas, houve um aumento da biomassa no período de estiagem. Os pontos da plataforma que mais sofreram influência do deságue foram os mais centrais (P3 e P4), devido ao predomínio dos ventos alísios de sudeste. Após análise das duas áreas, observou-se que os estuários encontram-se poluídos e que no porto do Recife a carga de matéria orgânica é bem mais elevada do que o Jaboatão, provocando maior efeito na plataforma adjacente. Em termo de dispersão de pluma dos rios, no porto do Recife a presença do dique de proteção provoca uma certa perturbação no sentido da corrente, limitando esta pluma, para a parte mais costeira, o que não foi observado na área do Jaboatão. / The continental shelf of Pernambuco is characterized by a gentle slope, it is narrow, shallow, almost entirely covered by biogenic carbonate sediments; the water in the area is warm and has a high salinity. This environment is affected by continental input, and acts as a final receptor of water, materials and other substances that are transported by river discharge. Thus, the coastal regions are the most affected by human action. This study aims to analyze the dynamics of chlorophyll-a and hydrological parameters on the inner shelf of Pernambuco adjacent to the Jaboatão and Capibaribe rivers. The samplings were performed bimonthly at one research site on the estuarine zone and four additional sites distributed on the platform, covering the dry and rainy seasons. Various environmental parameters such as chlorophyll-a, depth, salinity, temperature, dissolved oxygen, oxygen saturation rate, pH, inorganic nutrients (ammonia, nitrite, nitrate, phosphate and silicate), and suspended particulate matter were analyzed. Rainfall was the most influent physical forcing to most parameters. In the Jaboatão River, chlorophyll-a ranged from 2.89 to 34.71 mg.m–3 in the estuary; and from 0.21 to 9,67 mg.m-3 at the platform. According to the PCA , the chlorophyll-a was directly related to temperature, oxygen saturation rate and inversely with the pH, water transparency and salinity. In the Port of Recife, chlorophyll-a ranged from 13.48 to 145.09 mg.m-3 in the estuary and from 0.24 to 19.29 mg.m-3 in the inner shelf. The PCA showed a direct relationship of chlorophyll-a with ammonia, phosphate and water transparency an inverse relationship with nitrate and suspended particulate matter. In both studied areas, there was an increase in biomass in the dry season. In the inner platform , The most central sites (P3 and P4) were the most influenced by river discharge, due to the dominance of trade winds from the southeast. After analysis of the two areas, it was observed that the estuaries are polluted and that, in the Port of Recife, the load organic matter is much higher than in Jaboatão causing greater effect on the adjacent platform. In regarding the river’s plume dispersion in the Port of Recife, the presence of the dike causes some disturbance in the direction of the current. The plume is then limited to the most coastal area. This fact was not observed in the Jaboatão area.

Kierkegaard's Nihilistic Leveling and the Internet

Sheets, Andrew 01 January 2017 (has links)
In the 1840s, Søren Kierkegaard argued that the creation of impersonal media through the newspaper would level down human possibilities by turning every action into a spectacle for publicity. Nearly 200 years later, with smartphones whipped out to capture the most meaningful and trivial events as soon as they begin, we can ask the question—was Kierkegaard right to be worried? This essay will construct a Kierkegaardian analytic argument that our society has been leveled derived from Kierkegaard’s views as expressed in his philosophical analysis of leveling and the present age contained in Two Ages: A Literary Review. After arguing that our society is leveled, I will give an account of how leveling has developed and briefly explain Kierkegaard’s solution to leveling. Lastly, I will extrapolate Kierkegaard’s views of the press to the Internet and argue that the Internet presents new technological developments that force him to hold contradictory views on impersonal media.

Vertébrés continentaux du Crétacé supérieur de Provence (Sud-Est de la France) / Continental Vertebrates of Upper Cretaceous from Provence (Southeastern France)

Tortosa, Thierry 09 September 2014 (has links)
L’étude menée dans cette thèse, révise les faunes continentales du Crétacé supérieur (Campanien, Maastrichtien) de Provence (Bouches-du-Rhône et Var). Les recherches ont été menées sur plusieurs points : établir un inventaire précis des gisements paléontologiques, établir une liste faunique exhaustive pour chaque gisement, corréler les différents sites dans la stratigraphie générale et étudier les caractéristiques de la faune provençale. L’inventaire des sites fossilifères provençaux tient compte de plus d’une dizaine de nouveaux sites.Le recensement faunique de ces sites révèle des compositions semblables, à hauts niveaux de rangs taxinomiques. Dans le détail, elle comporte de légères variations selon l’âge des gisements, la localisation géographique et le contexte environnemental. L’actualisation des données met en évidence une richesse taxinomique bien plus importante que précédemment estimée. Le repositionnement stratigraphique des sites provençaux dans le Crétacé supérieur a été effectué à l’aide de marqueurs biostratigraphiques classiques et de l’oostratigraphie, permettant ainsi de corriger l’âge de certains sites historiques.L’examen de la paléobiodiversité provençale a tenu compte de la variabilité (intra ou interspécifique) et de la définition de nouveaux taxons. La variabilité/diversité de certains (titanosaures, Rhabdodon, théropodes ; nodosauridés) a été estimée grâce à l’utilisation de morphotypes.En caractérisant la faune provençale, ce travail pose les bases de l’étude de la faune à l’échelle de l’île ibéro-armoricaine. A l’échelle provençale, cette faune présente des caractéristiques d’une évolution en milieu insulaire avec quelques spécificités. / The study led within the framework of this thesis, reports on the Upper Cretaceous continental faunae (Campanian, Maastrichtian) of Provence (Boûches-du-Rhone and Var).Researches were focused on several aspects: Establish a precise inventory of the known paleontological deposits; establish a faunal exhaustive list for each deposit, correlate the various sites in the general stratigraphy and study the characteristics of Provencal fauna. Provencal fossil inventory takes into account more than about ten new localities.The fauna inventory of all these sites reveals similar compositions at high taxonomic levels. However, in detail, this fauna contains light variations according to the age of the localities, the geographical location and the environmental context. Data updating highlights a taxonomic richness more important than previously estimated. The stratigraphic reposition of the various localities from Provence in the Upper Cretaceous was carried out by the use of classic biostratigraphic markers and oostratigraphy, which allowed correcting the age of some historical sites.The study of paleobiodiversity in Provence took into account the variability (intra or interspecific) and the definition of new taxa. The variability/diversity of some taxa (titanosaurs, Rhabdodon, theropods, nodosaurids) was estimated thanks to the use of precise morphotypes.By characterizing the fauna from Provence, this work establishes the bases of the study of the Fauna on ibero-Armorican island (which includes Provence). At the Provence scale, this fauna presents many characteristics of an evolution in island environment with some evolutionary specificities.

As amostras foram obtidas pelo Navio Oceanografico “Antares” da Marinha do Brasil, em realizadas quatro campanhas: I (em 1995), II(em 1997), III (em 1998) e IV (em 2000). Em laboratório, a meiofauna foi extraída pelo método de decantação (com elutriação manual) e peneiramento úmido. Em cada amostra, foram retirados 100 Nematoda para identificação ao nível genérico, através do uso dechave pictorial. Os padrões de distribuição foram analisados considerando-se três fatores (profundidade, campanhas, tipo do sedimento de fundo). A meiofauna foi composta por 22 grupos taxonômicos: Oligochaeta, Polychaeta, Acari, Amphipoda, Cladocera, Copepoda, Cumacea, Isopoda, Ostracoda, Tanaidacea, Bivalvia, Gastropoda, Polyplacophora, Turbellaria, Insecta, Kinorhyncha, Gastrotricha, Nematoda, Priapulida, Rotifera, Sipuncula e Tardigrada. Os Nematoda dominaram nas amostras, representando 43% do total de indivíduos coletados, seguidos dos Copepoda (35%) e Polychaeta (12%). Um total de 7865 nematódeos foram identificados e distribuídos em oito ordens (Enoplida, Triplonchida, Chromadorida, Desmodorida, Desmoscolecida, Monhysterida, Araeolaimida and Plectida), 37 famílias e 170 gêneros. As famílias Desmodoridae, Chromadoridae e Xyalidae mostraram os maiores números de gêneros. Considerando as diferentes campanhas, 28 gêneros representaram mais de 70% do total dos Nematoda estudados. A profundidade foi o único fator que mostrou significância na estrutura da comunidade. Entretanto, informações da literatura indicam que essa variável poderia estar, indiretamente, refletindo outras variáveis, como a disponibilidade de alimento. / The goal of this study was characterized the meiofauna and, specially, marine nematodes at the northeastern Brazil continental shelf, which were collected during the REVIZEE program. Samples were obtainedby the oceanographic vessel "Antares" Navy of Brazil, in four campaigns: I (in 1995), II (in 1997), III (in 1998) and IV (in 2000). In the laboratory, meiofauna was separated by decantation (with agitation) method and wet sieving. In each sample, one hundred individuals of nematodes were picked out for identification at genus level, using a pictorial key. The distribution patterns were analyzed considering three factors (depth, campaigns, bottom sediment type). Meiofauna was composed by 22 groups: Oligochaeta, Polychaeta, Acari, Amphipoda, Cladocera, Copepoda, Cumacea, Isopoda, Ostracoda, Tanaidacea, Bivalvia, Gastropoda, Polyplacophora, Turbellaria, Insecta, Kinorhyncha, Gastrotricha, Nematoda, Priapulida, Rotifera, Sipuncula and Tardigrada. Nematodes were dominant in the samples, representing 43% of the total individuals, followed by Copepoda (35%) and Polychaeta (12%).A total of 7865 nematodes were identified and distributed in eight orders (Enoplida, Triplonchida, Chromadorida, Desmodorida, Desmoscolecida, Monhysterida, Araeolaimida and Plectida), 37 families and 170 genera. The families Desmodoridae, Chromadoridae and Xyalidae showed the highest number of genera. Considering the different campaigns, 28 genera represented 70% of the total of studied nematodes. The depth was the only factor that showed a significant on the community structure. Although, literature information indicated that this variable could be, indirectly, reflected other variables, like food available.

Those Left Behind: Heidegger on Grief and Mourning

Earle-Lambert, Alexandra T. 10 1900 (has links)
<p>In <em>Being and Time</em> Martin Heidegger explores the role that death plays in our lives and consequently the impact that the death of others has on the lives of those around them. Since Heidegger understands our existence to be structured by our being toward death and our being in the world with others, the impact of death on society will inevitably play a significant role.</p> <p>In this thesis I investigate the disconnect that exists between the traditional literature on death and mourning as developed by theorists like Elizabeth Kubler-Ross and others and the experiences of mourners themselves. I argue that the disconnect that exists points to and deep seated confusion about the death of the self and the death of others</p> <p>I identify some of the striking commonalities in the experiences of mourners and the lack of recognition of these experiences in the traditional literature. I also examine the role of traditional mourning practices and the impact they have on the mourners experience.</p> <p>I maintain that collectively we are profoundly confused about how to deal with the deaths of others, and the lack of modern western mourning practices is evidence of this. However, I believe that individually, we have some understanding of how to approach the death of another, and that this becomes evident when we are forced to experience this loss. I argue that a Heideggerian understanding of death and mourning more accurately represents the experience of the death of others and, if endorsed, would allow for a more personal experience of mourning because of Heidegger’s unique understanding of the role death plays in our lives and the significance of other people in our lives.</p> / Master of Arts (MA)

This report seeks to examine the organization in which this writer performed an internship as partial fulfillment for the Master of Arts in Arts Administration degree granted by the University of New Orleans. Although performed in a for-profit making rather than nonprofit setting, this internship, performed at the Hotel Inter-Continental, makes a valuable contribution to my professional career. The internship began January 23, 1998 and ended on November 13, 1998. The reason this writer chose to perform the internship at a hospitality lodging facility was to gain experience in VIP relations, managerial planning and controlling, and overview of hospitality industry. The internship was largely successful, as the writer gained the anticipated experience while making a significant contribution to the ongoing operations of the Hotel InterContinental. The writer is currently employed as a full-time employee as the Assistant Guest Relations Manager.
