Could the library be dismantled/role of unique holdings in modern times

I have been asked by administration, how much of our collection could go into storage. They optimistically hoping for a room or two for faculty/staff offices, as some buildings need renovation or need to be closed due to safety issues. Clearly, much of the population believes that all/most library materials are available on-line – free. I will present the results of our survey’s of material held and available on-line and space “freed” thanks to archiving. How little space is freed.

Late Transition Metals Supported by Aryl Ethers and Phenoxides Bearing Pendant Phosphines: Mechanistic Insights Relevant to Ether C-O Bond Cleavage

Terphenyl diphosphines bearing pendant ethers were prepared to provide mechanistic insight into the mechanism of activation of aryl C–O bonds with Group 9 and Group 10 transition metals. Chapters 2 and 3 of this dissertation describe the reactivity of compounds supported by the model phosphine and extension of this chemistry to heterogenous C–O bond activation.

Chapter 2 describes the synthesis and reactivity of aryl-methyl and aryl-aryl model systems. The metallation of these compounds with Ni, Pd, Pt, Co, Rh, and Ir is described. Intramolecular bond activation pathways are described. In the case of the aryl-methyl ether, aryl C–O bond activation was observed only for Ni, Rh, and Ir.

Chapter 3 outlines the reactivity of heterogenous Rh and Ir catalysts for aryl ether C–O bond cleavage. Using Rh/C and an organometallic Ir precursor, aryl ethers were treated with H2 and heat to afford products of hydrogenolysis and hydrogenation. Conditions were modified to optimize the yield of hydrogenolysis product. Hydrogenation could not be fully suppressed in these systems.

Appendix A describes initial investigations of bisphenoxyiminoquinoline dichromium compounds for selective C2H4 oligomerization to afford α-olefins. The synthesis of monometallic and bimetallic Cr complexes is described. These compounds are compared to literature examples and found to be less active and non-selective for production of α-olefins.

Appendix B describes the coordination chemistry of terphenyl diphosphines, terphenyl bisphosphinophenols, and biphenyl phosphinophenols proligands with molybdenum, cobalt, and nickel. Since their synthesis, terphenyl diphosphine molybdenum compounds have been reported to be good catalysts for the dehydrogenation of ammonia borane. Biphenyl phosphinophenols are demonstrated provide both phosphine and arene donors to transition metals while maintaining a sterically accessible coordination sphere. Such ligands may be promising in the context of the activation of other small molecules.

Appendix C contains relevant NMR spectra for the compounds presented in the preceding sections.

Osteometric analysis of the scapula and humerus of Rangifer tarandus and Cervus elaphus : A contribution to the discrimination of Late Pleistocene cervids

Fossil remains of reindeer (Rangifer tarandus) occurring outside their present range are an important indicator of formerly cold climatic conditions, but are easily confused with those of the red deer (Cervus elaphus). The locality of Kiputz IX has yielded one of the best-preserved Late Pleistocene reindeer populations of the southern Pyrenees, occurring in association with Bison priscus and the much more abundant Cervus elaphus. Fossil remains from this site are mostly complete and not affected by human intervention, thus creating the perfect conditions for reliable osteometric analyses. Here, we quantify diagnostic morphological features of the scapula and the humerus of Cervus elaphus and Rangifer tarandus to establish the potential of these bones to aid in interspecific discrimination. In the case of the scapula, the best species discriminator is the ratio of the minimum anteroposterior diameter of the scapular neck and the development of the articular process, while the breadth of the trochlea is the best discriminator in the case of the humerus.

Island life in the Cretaceous - faunal composition, biogeography, evolution, and extinction of land-living vertebrates on the Late Cretaceous European archipelago

The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact. The terrestrial fossil record of Late Cretaceous Europe is becoming increasingly better understood, based largely on intensive fieldwork over the past two decades, promising new insights into latest Cretaceous faunal evolution. We review the terrestrial Late Cretaceous record from Europe and discuss its importance for understanding the paleogeography, ecology, evolution, and extinction of land-dwelling vertebrates. We review the major Late Cretaceous faunas from Austria, Hungary, France, Spain, Portugal, and Romania, as well as more fragmentary records from elsewhere in Europe. We discuss the paleogeographic background and history of assembly of these faunas, and argue that they are comprised of an endemic 'core' supplemented with various immigration waves. These faunas lived on an island archipelago, and we describe how this insular setting led to ecological peculiarities such as low diversity, a preponderance of primitive taxa, and marked changes in morphology (particularly body size dwarfing). We conclude by discussing the importance of the European record in understanding the end-Cretaceous extinction and show that there is no clear evidence that dinosaurs or other groups were undergoing long-term declines in Europe prior to the bolide impact.

Visões da modernidade nas histórias em quadrinhos: Gotham e Metrópolis em finais de 1930

Metrópolis e Gotham são as cidades imaginárias das histórias em quadrinhos que, respectivamente, ambientam as aventuras do Super-Homem e Batman. Estes dois super-heróis foram criados nos Estados Unidos em finais da década de 1930 e continuam a povoar a vida de crianças e adultos oito décadas depois de sua concepção. O objetivo desta dissertação é fazer uma análise das cidades do Super-Homem e Batman em seu contexto de criação por meio de uma análise etnográfica da literatura em quadrinhos. Objetiva-se analisar as representações dessas cidades ficcionais em relação com as questões vividas pelas grandes cidades norte-americanas de sua época, como crime, migração e delinquência. Para tanto, analisa-se as primeiras histórias dos referidos super-heróis publicadas desde a sua criação em 1938 e 1939 até a entrada dos Estados Unidos na Segunda Guerra Mundial, em dezembro de 1941. Discute-se a questão da dupla identidade, da liberdade e do anonimato nas grandes cidades a partir do gênero de super-heróis, bem como contextualiza-se a criação dos quadrinhos como um meio de comunicação de massa nascido no ambiente moderno e urbano. A tese central desta dissertação gira em torno da discussão sobre cidades e Modernidade. Considera-se Gotham e Metrópolis como representações que refletem pontos de vista distintos sobre as grandes cidades modernas. A primeira é uma cidade noturna e violenta de crimes relacionados com a loucura, o crime organizado e a migração. Subjaz aqui a noção de que a modernidade, tendo como locus as grandes cidades, seria um fator que desagrega a vida social levando os habitantes de Gotham City a enfrentar um cotidiano de conflitos, seja com criminosos, loucos ou imigrantes. Metrópolis, por sua vez, enfrenta em seu cotidiano problemas técnicos e crimes de cunho moral, sendo uma cidade diurna de linhas retas e prédios de estilos arquitetônicos modernistas retratados a partir de imagens panorâmicas que destacam seus prédios e arranha-céus iluminados, enquanto Gotham é representada como uma cidade escura de prédios monolíticos que se repetem indistintamente em seu horizonte. Por mais ficcionais, utópicas ou distópicas que possam ser as cidades das histórias em quadrinhos elas são representações que se relacionam com o imaginário da época e sociedade em que foram criadas. Esta dissertação compreende Gotham City e Metrópolis como sínteses de concepções urbanas modernas, relacionando-as com correntes urbanísticas presentes nas primeiras décadas do século XX e com questões colocadas pelo pensamento social da Escola de Chicago de Sociologia.

Trabalho, logo existo: o sentido do trabalho para os executivos e as práticas corporativas contemporâneas

Essa pesquisa de mestrado pretende compreender as relações entre: o homem executivo, o trabalho e as práticas corporativas contemporâneas, em uma sociedade capitalista, denominada nesse estudo, modernidade tardia. Para o estudo desse tema foram priorizados pontos de reflexão relacionados à prática corporativa, tais como: pensar o trabalho na contemporaneidade observando suas características que se aproximam e se distanciam de outros momentos históricos; entender o trabalho, seus significados, suas transformações e suas estratégias atuais; refletir a respeito da perspectiva que o homem tem sobre o tempo e sua relação com a mudança do seu modo de viver; discutir o processo de desumanização do trabalho e das relações interpessoais na contemporaneidade; conhecer as atitudes do homem diante do trabalho e da vida em uma sociedade capitalista; observar e descrever a configuração atual do mercado de trabalho em algumas empresas privadas nacionais e multinacionais no Rio de Janeiro. O estudo das questões citadas permitiu tecer articulações sobre como o homem contemporâneo se relaciona com o trabalho corporativo e com os demais aspectos da vida, bem como sobre o estreitamento do tempo livre e encurtamento da vida em função do culto da alta performance. A escolha metodológica realizada nesta pesquisa é a abordagem qualitativa e método de entrevista narrativa, que conjuga reflexões teóricas à investigação empírica, colocando em questão a realidade cotidiana de profissionais que ocupam ou ocuparam posições de liderança em empresas. As modificações na importância e desdobramentos do trabalho observados atualmente estão relacionadas com as alterações na maneira como nossa sociedade tem lidado com o tempo, sua aceleração e com a vida. Vida entendida de forma mais ampla, onde haja espaço para a realização profissional e pessoal em diferentes espaços, bem como a possibilidade de execução de um trabalho que coadune motivações, interesses e potencialidades do indivíduo com uma contribuição efetiva para a sociedade, alinhada aos valores individuais. A opção de utilizar a terminologia sociedade da modernidade tardia em detrimento de sociedade atual decorre da observação da progressiva incorporação dos ideais capitalistas associados à aceleração do tempo e das maneiras de vivê-lo, por qual vem passando os processos produtivos, o trabalho, e as demais dimensões da vida humana. O trabalho no mundo corporativo obedece a regras particulares, que além de articuladas ao modelo econômico vigente, o capitalista, embute práticas e rituais que enfatizam o culto da alta performance. A presente pesquisa pretende analisar o trabalho dos executivos. Para isso, buscaremos analisá-lo segundo os modelos adotados em algumas empresas privadas, que consideraremos como o mundo corporativo e as implicações da adoção desses modelos para o exercício de uma vida mais plena de sentido existencial, a partir da minha experiência corporativa e da análise das entrevistas com executivos.

The effect of organotin and copper sulfate on the late development and presettlement behavior of the hard clam Mercenaria mercenaria

The effect of organotin compounds and copper, commonly used as antifouling agent, were studied on Mercenaria mercernaria larvae. They were reared under usual hatchery conditions until they reached 190 um in diameter. The larvae were subjected to four compounds, tributylin chloride (TBT), monobutyltin chloride (MBT), trimethyltin chloride (TMT), cupric sulfate (CuSo4) plus control. Mortality was measured at 24, 48 h, and 96h. Behavioral and/or metamorphic changes were recorded in triplicate at 24-48 and 96 h. The appearance in swimming larvae of a functional foot was considered a sign of competence to set and was recorded as a "pediveliger". Swimming larvae were considered as larvae that have not yet reached their total development and they were recorded as "swimming". Larvae that did not show foot or swimming activity and were static but alive on the bottom were recorded as "bottom". TBT was found to completely inhibit swimming activity at sublethal concentrations throughout the period of observation. Copper and MBT inhibited swimming from 48 h, TMT did not inhibit swimming activity at any of the times recorded. The four compounds ranked in order of decreasing toxicity were TBT>TMT>CU>MBT.

The western blue groper (Achoerodus gouldii), a protogynous hermaphroditic labrid with exceptional longevity, late maturity, slow growth, and both late maturation and sex change

The western blue groper (Achoerodus gouldii) is shown to be a temperate protogynous hermaphrodite, which spawns between early winter and mid-spring. Because A. gouldii changes body color at about the time of sex change, its color can be used as a proxy for sex for estimating the size and age at sex change and for estimating growth when it is not possible to use gonads for determining the sex of this fish. The following characteristics make A. gouldii highly susceptible to overfishing: 1) exceptional longevity, with a maximum age (70 years) that is by far the greatest yet estimated for a labrid; 2) slow growth for the first 15 years and little subsequent growth by females; and 3) late maturation at a large total length (TL50 = 653 mm) and old age (~17 years) and 4) late sex change at an even greater total length (TL50 = 821 mm) and age (~35 years). The TL50 at maturity and particularly at sex change exceeded the minimum legal total length (500 mm) of A. gouldii and the lengths of many recreationally and commercially caught fish. Many of these characteristics are found in certain deep-water fishes that are likewise considered susceptible to overfishing. Indeed, although fishing effort for A. gouldii in Western Australia is not particularly high, per-recruit analyses indicate that this species is already close to or fully exploited.

Ancient DNA from South-East Europe Reveals Different Events during Early and Middle Neolithic Influencing the European Genetic Heritage

The importance of the process of Neolithization for the genetic make-up of European populations has been hotly debated, with shifting hypotheses from a demic diffusion (DD) to a cultural diffusion (CD) model. In this regard, ancient DNA data from the Balkan Peninsula, which is an important source of information to assess the process of Neolithization in Europe, is however missing. In the present study we show genetic information on ancient populations of the South-East of Europe. We assessed mtDNA from ten sites from the current territory of Romania, spanning a time-period from the Early Neolithic to the Late Bronze Age. mtDNA data from Early Neolithic farmers of the Starcevo Cris culture in Romania (Carcea, Gura Baciului and Negrilesti sites), confirm their genetic relationship with those of the LBK culture (Linienbandkeramik Kultur) in Central Europe, and they show little genetic continuity with modern European populations. On the other hand, populations of the Middle-Late Neolithic (Boian, Zau and Gumelnita cultures), supposedly a second wave of Neolithic migration from Anatolia, had a much stronger effect on the genetic heritage of the European populations. In contrast, we find a smaller contribution of Late Bronze Age migrations to the genetic composition of Europeans. Based on these findings, we propose that permeation of mtDNA lineages from a second wave of Middle-Late Neolithic migration from North-West Anatolia into the Balkan Peninsula and Central Europe represent an important contribution to the genetic shift between Early and Late Neolithic populations in Europe, and consequently to the genetic make-up of modern European populations.

Nous sommes tousjours au dela : a negação narrative do sujeito modern em Sur des vers de Virgile (ensaios III, cap.V) de Michel de Motaigne

Investigando a apresentação das ideias em Sobre versos de Virgílio, a tese demonstra como sua estruturação ambígua, onde tudo é constantemente negado por seus contrários, leva a um contínuo estado de confusão e perplexidade, tornando impossível a determinação lógica dos conceitos e conduzindo a um progressivo esvaziamento do texto enquanto signo direto do pensamento do autor. Por outro lado, partindo de uma perspectiva hermenêutica influenciada pela anatomia, a análise mostra que o uso sistemático e criativo das instâncias narrativas (autor, narrador, signatário), juntamente com a reunificação textual de diferentes Montaignes (presentes nos diversos estágio editoriais do ensaio), acaba por dissolver a própria noção de identidade a si do autor, tendo por consequência imediata sua disseminação em vários sujeitos diversos e contraditórios e, por fim, colocando em xeque a clássica percepção dos Ensaios com o nascimento da subjetividade moderna.

Quahogs in Eastern North America: Part II, History by Province and State

The northern quahog, Mercenaria mercenaria, ranges along the Atlantic Coast of North America from the Canadian Maritimes to Florida, while the southern quahog, M. campechiensis, ranges mostly from Florida to southern Mexico. The northern quahog was fished by native North Americans during prehistoric periods. They used the meats as food and the shells as scrapers and as utensils. The European colonists copied the Indians treading method, and they also used short rakes for harvesting quahogs. The Indians of southern New England and Long Island, N.Y., made wampum from quahog shells, used it for ornaments and sold it to the colonists, who, in turn, traded it to other Indians for furs. During the late 1600’s, 1700’s, and 1800’s, wampum was made in small factories for eventual trading with Indians farther west for furs. The quahoging industry has provided people in many coastal communities with a means of earning a livelihood and has given consumers a tasty, wholesome food whether eaten raw, steamed, cooked in chowders, or as stuffed quahogs. More than a dozen methods and types of gear have been used in the last two centuries for harvesting quahogs. They include treading and using various types of rakes and dredges, both of which have undergone continuous improvements in design. Modern dredges are equipped with hydraulic jets and one type has an escalator to bring the quahogs continuously to the boats. In the early 1900’s, most provinces and states established regulations to conserve and maximize yields of their quahog stocks. They include a minimum size, now almost universally a 38-mm shell width, and can include gear limitations and daily quotas. The United States produces far more quahogs than either Canada or Mexico. The leading producer in Canada is Prince Edward Island. In the United States, New York, New Jersey, and Rhode Island lead in quahog production in the north, while Virginia and North Carolina lead in the south. Connecticut and Florida were large producers in the 1990’s. The State of Tabasco leads in Mexican production. In the northeastern United States, the bays with large openings, and thus large exchanges of bay waters with ocean waters, have much larger stocks of quahogs and fisheries than bays with small openings and water exchanges. Quahog stocks in certified beds have been enhanced by transplanting stocks to them from stocks in uncertified waters and by planting seed grown in hatcheries, which grew in number from Massachusetts to Florida in the 1980’s and 1990’s.
