Characterization of Opsin Gene Alleles Affecting Color Vision in a Wild Population of Titi Monkeys (Callicebus brunneus)

The color vision of most platyrrhine primates is determined by alleles at the polymorphic X-linked locus coding for the opsin responsible for the middle- to long-wavelength (M/L) cone photopigment. Females who are heterozygous at the locus have trichromatic vision, whereas homozygous females and all males are dichromatic. This study characterized the opsin alleles in a wild population of the socially monogamous platyrrhine monkey Callicebus brunneus (the brown titi monkey), a primate that an earlier study suggests may possess an unusual number of alleles at this locus and thus may be a subject of special interest in the study of primate color vision. Direct sequencing of regions of the M/L opsin gene using feces-, blood-, and saliva-derived DNA obtained from 14 individuals yielded evidence for the presence of three functionally distinct alleles, corresponding to the most common M/L photopigment variants inferred from a physiological study of cone spectral sensitivity in captive Callicebus.

Evolutionary Insights from Bat Trypanosomes: Morphological, Developmental and Phylogenetic Evidence of a New Species, Trypanosoma (Schizotrypanum) erneyi sp nov., in African Bats Closely Related to Trypanosoma (Schizotrypanum) cruzi and Allied Species

Parasites of the genus Trypanosoma are common in bats and those of the subgenus Schizotrypanum are restricted to bats throughout the world, with the exception of Trypanosoma (Schizotrypanum) cruzi that also infects other mammals and is restricted to the American Continent. We have characterized trypanosome isolates from Molossidae bats captured in Mozambique, Africa. Morphology and behaviour in culture, supported by phylogenetic inferences using SSU (small subunit) rRNA, gGAPDH (glycosomal glyceraldehyde 3-phosphate dehydrogenase) and Cyt b (cytochrome b) genes, allowed to classify the isolates as a new Schizotrypanum species named Trypanosoma (Schizotrypanum) erneyi sp. nov. This is the first report of a Schizotrypanum species from African bats cultured, characterized morphologically and biologically, and positioned in phylogenetic trees. The unprecedented finding of a new species of the subgenus Schizotrypanum from Africa that is closest related to the America-restricted Trypanosoma (Schizotrypanum) cruzi marinkellei and T. cruzi provides new insights into the origin and evolutionary history of T. cruzi and closely related bat trypanosomes. Altogether, data from our study support the hypothesis of an ancestor trypanosome parasite of bats evolving to infect other mammals, even humans, and adapted to transmission by triatomine bugs in the evolutionary history of T. cruzi in the New World.

Review of the Genus Cathorops (Siluriformes: Ariidae) from the Caribbean and Atlantic South America, with Description of a New Species

The New World genus Cathorops in the family Ariidae (Sea Catfishes) includes species that inhabit estuarine and coastal waters as well as freshwaters, playing an important role in Neotropical coastal and estuarine fisheries. The relatively conserved external morphology coupled with the marked sexual dimorphism and ontogenetic variation makes it difficult to recognize and diagnose the species. One of the major problems concerns the nomenclatural and geographical limits, of C. spixii, described from tropical Brazil and often treated as the only coastal marine species in the genus from the Western Atlantic. Examination of types of nominal species as well as comprehensive collections of non-types from Caribbean and Atlantic South America, lead us to conclude that C. spixii is restricted to Brazil and that C. nuchalis is a valid species, ranging from Venezuela to Guyana. The nominal species Arius laticeps, Arius nigricans, and Arius variolosus are synonyms of C. nuchalis, C. spixii, and C. arenatus, respectively. We also describe a new species in the Cathorops mapale species group from Colombia and Venezuela.

Parasites reveal movement of bats between the New and Old Worlds

The global distribution of bat taxa indicates that the Atlantic and Pacific Oceans are effective barriers to movement between the Old and New Worlds. For instance, one of the major suborders, Yinpterochiroptera, has an exclusively Old World distribution, and within the other, Yangochiroptera, no species and only five genera are common to both. However, as bats are sometimes blown out to sea, and have colonised isolated islands, occasional natural movement between the New and Old Worlds does appear to be possible. Here we identify new genotypes of a blood parasite, Trypanosoma dionisii, in Old World bats that are closely related to South American strains. Using highly conservative calibration points, divergence of Old and New World strains is estimated to have occurred 3.2-5.0 million years ago (MYA), depending on the method used (upper 95% CL for maximum time 11.4 MYA). The true date of divergence is likely to be considerably more recent. These results demonstrate that taxon-specific parasites can indicate historical movements of their hosts, even where their hosts may have left no lasting phylogenetic footprint.

Origins and evolution of VNTR loci: The apolipoprotein B 3$\sp\prime$ VNTR

I studied the apolipoprotein (apo) B 3$\sp\prime$ variable number tandem repeat (VNTR) and did computer simulations of the stepwise mutation model to address four questions: (1) How did the apo B VNTR originate? (2) What is the mutational mechanism of repeat number change at the apo B VNTR? (3) To what extent are population and molecular level events responsible for the determination of the contemporary apo B allele frequency distribution? (4) Can VNTR allele frequency distributions be explained by a simple and conservative mutation-drift model? I used three general approaches to address these questions: (1) I characterized the apo B VNTR region in non-human primate species; (2) I constructed haplotypes of polymorphic markers flanking the apo B VNTR in a sample of individuals from Lorrain, France and studied the associations between the flanking-marker haplotypes and apo B VNTR size; (3) I did computer simulations of the one-step stepwise mutation model and compared the results to real data in terms of four allele frequency distribution characteristics.^ The results of this work have allowed me to conclude that the apo B VNTR originated after an initial duplication of a sequence which is still present as a single copy sequence in New World monkey species. I conclude that this locus did not originate by the transposition of an array of repeats from somewhere else in the genome. It is unlikely that recombination is the primary mutational mechanism. Furthermore, the clustered nature of these associations implicates a stepwise mutational mechanism. From the high frequencies of certain haplotype-allele size combinations, it is evident that population level events have also been important in the determination of the apo B VNTR allele frequency distribution. Results from computer simulations of the one-step stepwise mutation model have allowed me to conclude that bimodal and multimodal allele frequency distributions are not unexpected at loci evolving via stepwise mutation mechanisms. Short tandem repeat loci fit the stepwise mutation model best, followed by microsatellite loci. I therefore conclude that there are differences in the mutational mechanisms of VNTR loci as classed by repeat unit size. (Abstract shortened by UMI.) ^

“O CRISTO AFOGADO: UMA NÃO-CRISTOLOGIA” RELIGIÃO, LITERATURA E PÓS-COLONIALISMO

O objetivo dessa tese é aprofundar, a partir do discurso pós-colonial, uma crise na perspectiva teológica da libertação. Esta promoveu, na década de 1970, uma reviravolta nos estudos teológicos no terceiro mundo. Para tanto, leremos um conto de Gabriel García Márquez chamado “El ahogado más hermosodel mundo” (1968) analizando e avaliando as estratégias políticas e culturais ali inscritas. Para levar a frente tal avaliação é preciso ampliar o escopo de uma visão que divide o mundo em secular/religioso, ou em ideias/práticas religiosas e não religiosas, para dar passo a uma visão unificada que compreende a mundanalidade, tanto do que é catalogado como ‘religioso’ quanto do que se pretende ‘não religioso’. A teologia/ciências da religião, como discurso científico sobre a economia das trocas que lidam com visões, compreensões e práticas de mundo marcadas pelo reconhecimento do mistério que lhes é inerente, possuem um papel fundamental na compreensão, explicitação, articulação e disponibilização de tais forças culturais. A percepção de existirem elementos no conto que se relacionam com os símbolos sobre Jesus/Cristo nos ofereceu um vetor de análise; entretanto, não nos deixamos limitar pelos grilhões disciplinares que essa simbologia implica. Ao mesmo tempo, esse vínculo, compreendido desde a relação imperial/colonial inerente aos discursos e imagens sobre Jesus-Cristo, embora sem centralizar a análise, não poderia ficar intocado. Partimos para a construção de uma estrutura teórica que explicitasse os valores, gestos, e horizontes mundanos do conto, cristológicos e não-cristológicos, contribuindo assim para uma desestabilização dos quadros tradicionais a partir dos quais se concebem a teologia e as ciências da religião, a obra de García Márquez como literatura, e a geografia imperial/colonial que postula o realismo ficcional de territórios como “América Latina”. Abrimos, assim, um espaço de significação que lê o conto como uma “não-cristologia”, deslocando o aprisionamento disciplinar e classificatório dos elementos envolvidos na análise. O discurso crítico de Edward Said, Homi Bhabha e GayatriSpivak soma-se à prática teórica de teólogas críticas feministas da Ásia, da África e da América Latina para formular o cenário político emancipatório que denominaremos teologia crítica secular.

A new extinct primate among the Pleistocene megafauna of Bahia, Brazil.

A nearly complete skeleton of a robust-bodied New World monkey that resembles living spider monkeys was recovered from undisturbed Pleistocene deposits in the Brazilian state of Bahia. The skeleton displays the highly specialized postcranial pattern typical of spider and woolly spider monkeys and shares cranial similarities to the spider monkey exclusively. It is generically distinct on the basis of its robustness (>20 kg) and on the shape of its braincase. This new genus indicates that New World monkeys nearly twice the size of those living today were part of the mammalian biomass of southern Amazonia in the late Pleistocene. The discovery of this specimen expands the known adaptive diversity of New World monkeys and demonstrates that they underwent body size expansion in the terminal Pleistocene, as did many other types of mammals.

Sistemática de transformação: desenvolvimento teórico para o alinhamento entre estratégia e cultura organizacional nos projetos de Lean

Desde o final do Século XX e início do Século XXI, estudos analisam a elevada taxa de insucesso ou insatisfação com os Programas de Lean. Esta taxa tem se demonstrado demasiadamente elevada, variando entre 66% e 90%. Como efeito deste insucesso, tem-se o desperdício de tempo, dinheiro, recursos e, talvez o pior, tem-se a propagação do medo nos agentes de mudança em empreitar novas iniciativas de mudança. Estudos apontam a falta de alinhamento de tais projetos com a Cultura Organizacional como uma das questões fundamentais deste insucesso. Partindo desta temática de pesquisa, este ensaio teórico pode ser caracterizado como uma abordagem qualitativa de análise do problema, de natureza básica de pesquisa buscando gerar conhecimentos novos e úteis às organizações, sem aplicação prática prevista neste primeiro estágio de pesquisa. A fonte de evidências para sustentar o modelo proposto foi revisão dos estudos de caso encontrados na literatura, sendo utilizadas tanto uma Revisão Bibliográfica Sistemática (RBS) quanto Exploratória, de tal maneira a buscar o \"estado da arte\" no campo de estudo. A Fundamentação Teórica do trabalho é baseada na literatura de quatro grandes campos de estudo: (i) Estratégia, (ii) Lean, (iii) Cultura Organizacional e (iv) Gestão de Mudanças. A RBS tem foco nas interseções destes grandes campos, agregando 190 trabalhos internacionais. Por sua vez, a Revisão Exploratória traz algumas das principais referências dos três campos de estudo, como: Edgar Schein, John Kotter, Kim Cameron, Robert Quinn, David Mann, dentre outros. Desta maneira, este trabalho estudou a influência da cultura organizacional nos projetos de transformação e, a partir da ruptura com a teoria atual, construiu e propôs uma sistemática teórica, intitulada de \"Sistemática de Transformação\" (ou simplesmente \"Sistemática T\"), a qual propõe o alinhamento entre três dimensões: Estratégia, Projeto de Transformação e Cultura Organizacional. Fazendo uso desta sistemática, é esperado que os agentes de mudança consigam ter um planejamento mais eficaz do processo de diagnóstico, avaliação e gestão da cultura organizacional alinhado à Estratégia e também ao Projeto de Transformação da organização, com ênfase nos Programas de Lean. A proposição e uso desta sistemática pode favorecer tanto a discussão acadêmica na área de Gestão de Operações sobre o tema, quanto fornecer subsídios para aplicações práticas mais eficazes.

A World that Counts: Mobilising the Data Revolution for Sustainable Development

In September 2015, the UN Member States are expected to commit to an ambitious new set of global goals for a new era of sustainable development. Achieving them will require an unprecedented joint effort on the part of governments at every level, civil society and the private sector, and millions of individual choices and actions. To be realised, the SDGs will require a monitoring and accountability framework and a plan for implementation. A commitment to realise the opportunities of the data revolution should be firmly embedded into the action plan for the SDGs, to support those countries most in need of resources, and to set the world on track for an unprecedented push towards a new world of data for change.

The words of God: Religious texts and the Counter -Reformation in the Spanish world

This dissertation analyzes a variety of religious texts such as catechisms, confession manuals, ecclesiastical legislation, saints' lives, and sermons to determine the definitions of orthodoxy held by the Spanish clergy and the origins of such visions. The conclusion posited by this research was that there was a definite continuity between the process of Catholic reform in Spain and the process of Catholic expansion into the New World in that the objectives and concerns of the Spanish clergy in Europe and the New World were very similar. This dissertation also analyzes sources that predated the Council of Trent and demonstrates that within the Iberian context the Council of Trent cannot be used as a starting date for the attempts at Catholic reform. In essence, this work concludes the Spanish clergy's activities were influenced by humanist concepts of models and model behaviour which is reflected in their attempt to form model Catholics in Spain and the New World and in their impulse to produce written texts as standards. ^
