Eclipta brasiliensis (Fisher, 1947) is transferred to Ischasioides Tavakilian & Peñaherrera-Leiva, 2003, and synonymized with I. crassitarsis (Gounelle, 1911). Ischasia m. atrocephala Fuchs, 1956 and Ischasia m. nigrovittata Fuchs, 1956, although without nomenclatural status, are confirmed as equal to I. crassitarsis. Ischasioides berkovae sp. nov. is described from Brazil. A key to the species of Ischasioides is provided.

In the 29 years following \"Our Common Future\" by the United Nations, there is considerable debate among governments, civil society, interest groups and business organisations about what constitutes sustainable development, which constitutes evidence for a contested discourse concerning sustainability. The purpose of this study is to understand this debate in the developing economic context of Brazil, and in particular, to understand and critique the social and environmental accounting [SEA] discursive constructions relating to the State-owned, Petrobras as well as to understand the Brazilian literature on SEA. The discourse theory [DT]-based analysis employs rhetorical redescription to analyse twenty-two reports from Petrobras from 2004-2013. I investigate the political notions by employing the methodological framework of the Logics of Critical Explanation [LCE]. LCE engenders five methodological steps: problematisation, retroduction, logics (social, political and fantasmatic), articulation and critique. The empirical discussion suggests that the hegemony of economic development operates to obfuscate, rhetorically, the development of sustainability, so as to maintain the core business of Petrobras conceived as capital accumulation. Equally, these articulations also illustrate how the constructions of SEA operate to serve the company\'s purpose with few (none) profound changes in integration of sustainability. The Brazilian literature on SEA sustains the status quo of neo-liberal market policies that operate to protect the dominant business case approach to maintain an agenda of wealth-creation in relation to social and environmental needs. The articulations of the case manifested in policies regarding, for example, corruption, which involved over-payments for contracts and unsustainable practices relating to the use of fossil fuels and demonstrated that there was antagonism between action and disclosure. The corruption scandal that emerged after SEA disclosures highlighted the rhetorical nature of disclosure when financial resources were subtracted from the company for political parties and engineering contractors hid facts through incomplete disclosures. The articulations of SEA misrepresent a broader context of the meanings associated with sustainability, which restricted the constructions of SEA to principally serve and represent the intention of the most powerful groups. The significance of SEA, then is narrowed to represent particular interests. The study argues for more critical studies as limited Brazilian literature concerning SEA kept a \'safe distance\' from substantively critiquing the constructions of SEA and its articulations in the Brazilian context. The literature review and the Petrobras\' case illustrate a variety of naming, instituting and articulatory practices that endeavour to maintain the current hegemony of development in an emerging economy, which allows Petrobras to continue to exercise significant profit at the expense of the social and environmental. The constructed idea of development in Petrobras\' discourses emphasises a rhetoric of wider development, but, in reality, these discourses were the antithesis of political, social and ethical developmental issues. These constructions aim to hide struggles between social inequalities and exploitation of natural resources and constitute excuses about a fanciful notion of rhetorical and hegemonic neo-liberal development. In summary, this thesis contributes to the prior literature in five ways: (i) the addition of DT to the analysis of SEA enhances the discussion of political elements such as hegemony, antagonism, logic of equivalence/difference, ideology and articulation; (ii) the analysis of an emerging economy such as Brazil incorporates a new perspective of the discussion of the discourses of SEA and development; (iii) this thesis includes a focus on rhetoric to discuss the maintenance of the status quo; (iv) the holistic structure of the LCE approach enlarges the understanding of the social, political and fantasmatic logics of SEA studies and; (v) this thesis combines an analysis of the literature and the case of Petrobras to characterise and critique the state of the Brazilian academy and its impacts and reflections on the significance of SEA. This thesis, therefore, argues for more critical studies in the Brazilian academy due to the persistence of idea of SEA and development that takes-for-granted deep exclusions and contradictions and provide little space for critiques.

The cohort Astigmatina is divided in two major groups: Psoroptidia, composed mainly by feather and fur mites, and Non-psoroptidia, a dominant component of the acarofauna in ephemeral habitats. In these environments Astigmatina usually are saprophages or feed on fungi or bacteria. Astigmatina protonymphs undergo a complete reorganization of the body structure leading to the production of heteromorphic deutonymphs, generally specialized for dispersion through phoresy using arthropods and vertebrates as phoronts. Although most Astigmatina occur in natural environments, some species live in anthropic environments, such as food deposits, where some of them became pests; some Astigmatina infest subterraneous plant organs. Despite their economic and ecological importance, studies on the diversity and taxonomy of Astigmatina in Brazil have been rare over the last decades. The general objective of this thesis was to collaborate to the knowledge of the diversity and to evaluate the potential practical uses of these mites in Brazil. For this, new genera and species were described, method for rearing dust mites was studied and the efficiency of Astigmatina as prey for edaphic predators was evaluated. A new species of Thyreophagus (Astigmatina: Acaridae) was described based on specimens collected in Brazil, the association of three other species of this genus with stored food was reviewed and a key to all species of this genus was prepared. The genus Neotropacarus (Astigmatina: Acaridae), commonly found on plant leaves, was reviewed with the redescription of two species and description of new species collected in Brazil and from the Philippines. Two new genera and seven new species of Acaridae associated with the bee family Apidae was described and a key to Acaridae genera in subfamily Horstiinae was prepared. Several species of Astigmatina were evaluated as prey for predatory mites Stratiolaelaps scimitus (Womersley) (Mesostigmata: Laelapidae) and Protogamasellopsis zaheri Abo-Shnaf, Castilho and Moraes (Mesostigmata: Rhodacaridae), which oviposited on all evaluated astigmatids, with Tyrophagus putrescentiae (Schrank) and Aleuroglyphus ovatus (Tropeau) (Acaridae) being the most suitable prey. Seven foods and two development period, 30 and 60 days, after the introduction of 400 females of two important dust mite species, Blomia tropicalis van Bronswijk, de Cock e Oshima and Dermatophagoides pteronyssinus (Trouessart) were evaluate. With the most suitable foods, the population growth were higher than 20.2 and 15.3 for B. tropicalis and D. pteronyssinus, respectively.

A espécie recente Eira barbara (Mustelidae, Carnivora) possui uma distribuição geográfica desde o México até o norte da Argentina. É um importante táxon a ser estudado como modelo anatômico dentre os mustelídeos, assim como um importante modelo para uma melhor compreensão e entendimento sobre a diversificação dos Mustelidae. Atualmente, os registros fósseis de E. barbara na América do Sul são bastante escassos e restritos às idades pleistocênicas, sendo que os estudos destes fósseis são frequentemente desprovidos de maiores esforços para realização de descrições morfológicas detalhadas e de estudos paleobiogeográficos. Assim como os estudos dos fósseis de E. barbara são limitados, constatou-se que o mesmo cenário é observado quanto aos estudos sobre a morfologia e biogeografia da espécie. Desta forma, o presente trabalho se propôs a: realizar uma revisão de todos os registros da espécie e de uma forma geral, contribuir para um melhor conhecimento sobre a morfologia sincraniana e sobre a história biogeográfica e paleobiogeográfica de E. barbara. Para tanto, os seguintes objetivos foram propostos: estudo e redescrição detalhada do fóssil UFAC-PV 036, proveniente do Pleistoceno final do Alto Rio Juruá do sudoeste da Amazônia Brasileira; descrição sincraniana comparada de estruturas morfológicas externas e internas, analisando caracteres intraespecíficos da espécie E. barbara; realização de análises multivariadas a fim de investigar variações geográficas sob o uso de caracteres craniométricos de E. barbara entre os diferentes biomas brasileiros. A revisão dos registros fósseis foi de grande importância para o estabelecimento dos verdadeiros registros de Eira na América do Sul e a redescrição de UFAC-PV 36 contribui para o melhor conhecimento morfológico e paleobiogeográfico da espécie. A descrição morfológica comparada do sincrânio de E. barbara contribui de forma significativa para o conhecimento sobre a morfologia da espécie bem como, a descrição de caracteres intraespecíficos proporcionam caracteres mais apropriados em matrizes morfológicas, fornecendo maior robustez nas análises filogenéticas futuras. Este trabalho propõe que E. barbara não possui diferenças craniométricas estatisticamente significativas entre os biomas brasileiros, porém, E. barbara caracteriza-se aqui como uma espécie dimórfica, na qual os machos possuem estruturas cranianas relativamente maiores do que as fêmeas.

O tema da loucura na obra pessoana tem sido objecto de várias aproximações interpretativas, decorrentes da multiplicidade de textos que fazem eco do fenómeno e da sua persistência enquanto topos ao longo de praticamente toda a sua produção. Na sua acepção literal, manteve constantes interferências com a dimensão empírica do autor sobretudo quando sustentadas na contingência de certos textos basilares, os quais têm vindo a ser questionados quanto ao seu valor estritamente testemunhal. Como fenómeno desde cedo relacionado com a criação artística, a loucura surge neste estudo não apenas na representatividade da condição distintiva do sujeito criador mas ainda como figuração da contingência que envolve qualquer acto criativo que tome a linguagem na sua dimensão essencialmente metafórica e ambígua. Neste sentido, o presente trabalho pretende a abertura de várias vias de leitura do fenómeno através da análise crítica dos vocabulários relativos a diferentes âmbitos e concepções de loucura e a sua relação com o génio (capítulos I e II), focando o seu interesse no que diz respeito a alguma produção pessoana pré-heteronímica, nomeadamente Charles Robert Anon, Alexander Search (capítulo III) e Jean Seul de Méluret (capítulo IV), a que acrescentaremos o Primeiro Fausto (capítulo IV), de modo a conseguirmos estabelecer uma possível relação entre as primeiras experiências de alterização e a descoberta simultânea da irredutibilidade do discurso literário face a tentativas de literalização e de racionalização da linguagem, defendidas por outros modelos (paradigma biologista). A identificação da ambiguidade e da ironia nas suas mais variadas acepções como componentes essenciais da aprendizagem do valor contingente do processo de criação contribuirá tanto para a definição da autonomização da literatura como para a redescrição moderna do sujeito criador, paradoxalmente investido do pathos criativo anunciado no Romantismo e confrontando-se com os seus limites, que corresponderão aos da própria linguagem, situação de crise de que a figuração do louco lúcido será um dos tópicos mais produtivos. ABSTRACT: The theme of madness in the Pessoa work has been the subject of several interpretive approaches, from the multiplicity of texts that echo the phenomenon and its persistence as a topos priority over virtually all its production. ln its physiological sense, remained constant interference with the empirical dimension of the author when sustained in the contingency of certain basic texts that have been questioned as to their strictly testimonial value. As early phenomenon associated with artistic creation, the madness in this study is not only representative in the distinctive condition of the subject creator but also as the contingency figuration involving any creative act to take the language mainly in its essential metaphorical and ambiguous dimension. Accordingly, this work intends to open several analysis manners of the phenomenon through critical analysis of vocabularies for different areas and concepts of madness and its special relationship with the genius (Chapters I and II), focusing its interest in respect to some of the previous-heteronomy Pessoa production, including Charles Robert Anon, Alexander Search (Chapter III) and Jean Seul de Méluret (Chapter IV), and the Primeiro Fausto (Chapter IV), among others, to establish a possible relationship between changing early experiences and the discovery simultaneous literary discourse of irreducibility in the face of the attempts of literacy and the rationalization of language defended by other models (biologist paradigm). The identification of the ambiguity and irony in its many different meanings as essential components of learning the contingent value of the creation process which will contribute to the definition of empowerment in the literature as to the redescription of the modem subject creator that paradoxically had the creative pathos announced in Romanticism and from the confrontation with its limits, which will correspond to the language itself, the crisis situation from which the mad-lucid figuration will be one of the most productive topics.
