O Amálgama: especulações acerca da proposta colaborativa Atrocidades Maravilhosas

A presente dissertação trata de propostas artísticas destinadas ao espaço público e que se organizam enquanto trabalhos colaborativos. Pretendemos situar a ação Atrocidades Maravilhosas (2000) enquanto proposta modificada e modulada conforme o interesse dos artistas participantes, bem como as condições ambientais as quais a ação estava sujeita. Por essa via, a investigação problematiza contextos culturais dos anos 1990 e 2000, mais especificamente, às unidades discursivas que contribuem para refletirmos sobre as ações coletivas. Pelas considerações de autores como Clair Bishop, MiwonKwon, André Mesquita e Steward Home, pretende-se pensar o espaço artístico contemporâneo ante à mercantilização da cultura vigente. Nesse ínterim, será questionada a identificação e a identidade entre atores sociais, bem como a relação entre os artistas e os espaços culturais os quais se destinam algumas propostas artísticas. Essa investigação adentra o território brasileiro do início do anos 2000 e, aponta por esse contexto, as afinidades de alguns coletivos com propostas artísticas em outras partes do mundo. Essa pesquisa trata ainda de assuntos tangente às negociações e conflitos inerentes aos projetos colaborativos a partir deles pretendemos repensar o espaço comunicacional ativado por esses grupos, buscando na descentralização dos discursos, a potência dos dissensos. Pretendemos, com esse panorama iluminar nas ações de participação efetiva, não as novas respostas ao projeto de democratização ou inclusão de culturas periféricas, mas novas perguntas sobre o antigo problema acerca da colonização cultural da arte

Variability in spawning frequency and reproductive development of the narrow-barred Spanish mackerel (Scomberomorus commerson) along the west coast of Australia

The narrow-barred Spanish mackerel (Scomberomorus commerson) is widespread throughout the Indo-West Pacific region. This study describes the reproductive biology of S. commerson along the west coast of Australia, where it is targeted for food consumption and sports fishing. Development of testes occurred at a smaller body size than for ovaries, and more than 90% of males were sexually mature by the minimum legal length of 900 mm TL compared to 50% of females. Females dominated overall catches although sex ratios within daily catches vary considerably and females were rarely caught when spaw n ing. Scomberomorus commerson are seasonally abundant in coastal waters and most of the commercial catch is taken prior to the reproductive season. Spawning occurs between about August and November in the Kimberley region and between October and January in the Pilbara region. No spawning activity was recorded in the more southerly West Coast region, and only in the north Kimberley region were large numbers of fish with spawning gonads collected. Catches dropped to a minimum when spawning began in the Pilbara region, when fish became less abundant in inshore waters and inclement weather conditions limited fishing on still productive offshore reefs. Final maturation and ovulation of oocytes took place within a 24-hour period, and females spawned in the afternoon-evening every three days. A third of these spawning females released batches of eggs on consecutive days. Relationships between length, weight, and batch fecundity are presented.

Distribution, feeding condition, and growth of Japanese Spanish mackerel (Scomberomorus niphonius) larvae in the Seto Inland Sea

Distribution of eggs and larvae and feeding and growth of larvae of Japanese Spanish mackerel (Scomberomorus niphonius) were investigated in relation to their prey in the Sea of Hiuchi, the Seto Inland Sea, Japan, in 1995 and 1996. The abundance of S. niphonius eggs and larvae peaked in late May, corresponding with that of clupeid larvae, the major prey organisms of S. niphonius larvae. The eggs were abundant in the northwestern waters and the larvae were abundant in the southern waters in late May in both years, indicating a southward drift during egg and yolksac stages by residual f low in the central part of the Sea of Hiuchi. Abundance of clupeid larvae in southern waters, where S. niphonius larvae were abundant, may indicate a spawning strategy on the part of first-feeding S. niphonius larvae to encounter the spatial and temporal peak in ichthyoplankton prey abundance in the Seto Inland Sea. Abundance of the clupeid larvae was higher in 1995 than in 1996. Feeding incidence (percentage of stomachs with food; 85.3% in 1995 and 67.7% in 1996) and mean growth rate estimated from otolith daily increments (1.05 mm/d in 1995 and 0.85 mm/d in 1996) of S. niphonius larvae in late May were significantly higher in 1995. Young-of-the-year S. niphonius abundance and catch per unit of fishing effort of 1-year-old S. niphonius in the Sea of Hiuchi was higher in 1995, indicating a more successful recruitment in this year. Spatial and temporal correspondence with high ichthyoplankton prey concentration was considered one of the important determinants for the feeding success, growth, and survival of S. niphonius larvae.

Democracia, socialismo e projeto de nação no Governo Lula (2003-2006)

A democracia e o socialismo foram dois eixos que nortearam a fundação do Partido dos Trabalhadores durante o processo de redemocratização. Nesse sentido, o interesse é investigar os sentidos atribuídos aos conceitos de democracia e socialismo nos discursos presidenciais de Luis Inácio Lula da Silva durante o primeiro mandato (2003-2006). Desse modo, o objetivo é analisar como o projeto petista e o seu principal protagonista dialogam com esse passado que se constitui como identidade do partido ao chegar ao poder tendo em vista a crescente moderação dos discursos, abandono progressivo de uma postura anticapitalista e enfraquecimento do vínculo com os movimentos sociais ao longo dos anos 90.Por outro lado, este trabalho pretende abordar as regularidades e objetos discursivos, dentro dos pronunciamentos de Lula, que consolidam o projeto petista como de integração nacional, um discurso de refundação da nação. Sendo assim, verificar qual a imagem construída dessa entidade social, as associações identitárias utilizadas e a ideia dos males da nação no discurso do presidente que se fundam no olhar presente, em um arquétipo de mudança por meio da utilização constante da expressão: "Nunca antes na História desse país".

Interação na produção e recepção de obras de arte contemporânea

A tese procura compreender quais ações sociais estão presentes na recepção e produção de obras de arte contemporânea. O ponto de vista da etnometodologia é de que os processos de interação são originários e formais, pois o sujeito fenomenológico não se percebe, é sempre o outro para o qual se dirige. E, ao mesmo tempo, as ações sociais e interpretações são orientadas por métodos (pressupostos e subentendidos) compartilhados entre agentes. Para investigar estes métodos, deve-se situá-los no contexto de uso, as circunstâncias concretas, que os tornam observáveis e relatáveis (accountable) por meio de operações de visibilização e/ou ocultamento, antecipação e/ou aguardo. A etnometodologia observa as ações sociais em situações rotineiras, nas quais os agentes lançam mão do conhecimento que compartilham e esperam que os outros façam o mesmo. É quando se age sem pensar. As artes são frequentemente analisadas segundo as diferenças produzidas nas relações cotidianas, oferecendo outros olhares e deslocamentos para o que já é habitual. Não negamos esta condição, mas compreendemos também que a observação de artes não se dá fora do mundo social. Cotidianamente, os agentes utilizam recursos de identificação das circunstâncias em que se encontram, do interlocutor com quem interage e do ambiente onde se insere. O que significa que estes recursos estão disponíveis a qualquer pessoa e são levados para o interior de galerias e museus, à revelia de observadores, artistas e instituições. Para qualquer um que ocupe a posição de observador da obra, as circunstâncias concretas da recepção (a obra, o texto da crítica, a fala do artista, a ação dos outros visitantes, etc.), exigem, deste agente, operações semelhantes às utilizadas no cotidiano. Estas operações foram investigadas nas entrevistas com público e artistas, nas quais se buscou reconhecer quais recursos e métodos compartilhados com a obra, o público, os outros artistas e a crítica, eles lançam mão quando ocupam as posições de observador ou produtor de obras de arte.

A Igreja no Brasil e o zelo pastoral de D. José Joaquim Justiniano Mascarenhas Castelo Branco: breve olhar sobre a implementação do catolicismo colonial e seus reflexos no sétimo episcopado carioca do século XVIII

A presente pesquisa aborda a formação da identidade da religião católica no Brasil colonial e seus reflexos nos desregramentos recorrentes na segunda metade do século XVIII, na diocese de São Sebastião do Rio de Janeiro durante o episcopado de D. José Joaquim Justiniano Mascarenhas Castelo Branco (1773 1805) tendo sido este o primeiro bispo a assumir o comando de sua diocese natal. O tema proposto aborda diretamente a complexa relação entre os poderes temporal, representado pelo Estado português personificado na figura da realeza , e o espiritual, pertencente à Igreja sua representatividade máxima no local varia de acordo com a posição ocupada pelos clérigos, respeitando-se, assim, a hierarquia eclesiástica (monges, freiras, padres, bispos etc.). Apesar da obrigatoriedade do catolicismo na colônia, a coroa metropolitana não foi capaz de dar o suporte necessário para o estabelecimento de uma religiosidade fiel às determinações do Concilio de Trento, conforme determinava o direito de Padroado. Isso levou à formação de um catolicismo colonial por vezes aparente. A miscigenação étnico-cultural deu brecha para o surgimento de praticas sincréticas e diferentes comportamentos sociais reprovados pela Igreja. O desvio de conduta era um problema que afetava, não só os fiéis, mas também o clero, sendo este composto na época por sacerdotes mal formados e alguns estrangeiros de índoles duvidosas. Assim, os bispos do Brasil do século XVIII tiveram que lidar com problemas que eram, na verdade, reflexo da realidade da estrutura colonizadora local onde, apesar de ter sido a Igreja uma importante aliada do Estado lusitano, e vice-versa, havia também grande rivalidade entre ambos. Dessa forma, ocorriam na época constantes embates entre as autoridades civil e religiosa, as quaisuniam-se e desuniam-se de acordo com seus interesses.

Maracanazo e Mineiratzen: Imprensa e Representação da Seleção Brasileira nas Copas do Mundo de 1950 e 2014.

O esporte, entre as suas diversas variantes, é meio de expressão das construções acerca da identidade nacional. O futebol atua como um elemento aglutinador de etnias e classes e é uma importante maneira de influenciar a visão que o brasileiro tem de si próprio. No Brasil, a Seleção funciona como instrumento unificador de nação, representante da cultura nacional. Ao representar os atletas e equipe, os meios de comunicação acabam por construir imagens que influenciam nos sentidos de pertencimento em relação ao objeto retratado. Por meio dos discursos adotados pela imprensa, atribuímos valores simbólicos que geram identificação. A disputa de uma Copa do Mundo FIFA é um momento em que o sentimento de nacionalidade é avivado diante da competição entre times de futebol que correspondem a Estados-nação. No entanto, os últimos anos teriam demonstrado uma queda de interesse do torcedor nacional pelo selecionado. O Brasil, por duas oportunidades, foi sede de um Mundial. E, nas duas ocasiões, a Seleção Brasileira sofreu derrotas e não conseguiu conquistar o título jogando em seu território. O trabalho, um estudo sobre Comunicação e Esporte, é uma análise dos textos dos jornais impressos O Globo e Folha na cobertura das Copas do Mundo de 1950 e 2014. Busca-se, uma vez que se percebera o vínculo simbólico entre o conceito de nação e o desempenho da Seleção nacional de futebol, entender como foram construídas as representações da equipe e, consequentemente, dos seus jogadores e quais amostras que podem identificar a relação de aproximação ou afastamento com os torcedores, nas competições que marcaram as duas principais derrotas da Seleção em cem anos de história.

Marine Vertebrates and Low Frequency Sound: Technical Report for LFA EIS

Over the past 50 years, economic and technological developments have dramatically increased the human contribution to ambient noise in the ocean. The dominant frequencies of most human-made noise in the ocean is in the low-frequency range (defined as sound energy below 1000Hz), and low-frequency sound (LFS) may travel great distances in the ocean due to the unique propagation characteristics of the deep ocean (Munk et al. 1989). For example, in the Northern Hemisphere oceans low-frequency ambient noise levels have increased by as much as 10 dB during the period from 1950 to 1975 (Urick 1986; review by NRC 1994). Shipping is the overwhelmingly dominant source of low-frequency manmade noise in the ocean, but other sources of manmade LFS including sounds from oil and gas industrial development and production activities (seismic exploration, construction work, drilling, production platforms), and scientific research (e.g., acoustic tomography and thermography, underwater communication). The SURTASS LFA system is an additional source of human-produced LFS in the ocean, contributing sound energy in the 100-500 Hz band. When considering a document that addresses the potential effects of a low-frequency sound source on the marine environment, it is important to focus upon those species that are the most likely to be affected. Important criteria are: 1) the physics of sound as it relates to biological organisms; 2) the nature of the exposure (i.e. duration, frequency, and intensity); and 3) the geographic region in which the sound source will be operated (which, when considered with the distribution of the organisms will determine which species will be exposed). The goal in this section of the LFA/EIS is to examine the status, distribution, abundance, reproduction, foraging behavior, vocal behavior, and known impacts of human activity of those species may be impacted by LFA operations. To focus our efforts, we have examined species that may be physically affected and are found in the region where the LFA source will be operated. The large-scale geographic location of species in relation to the sound source can be determined from the distribution of each species. However, the physical ability for the organism to be impacted depends upon the nature of the sound source (i.e. explosive, impulsive, or non-impulsive); and the acoustic properties of the medium (i.e. seawater) and the organism. Non-impulsive sound is comprised of the movement of particles in a medium. Motion is imparted by a vibrating object (diaphragm of a speaker, vocal chords, etc.). Due to the proximity of the particles in the medium, this motion is transmitted from particle to particle in waves away from the sound source. Because the particle motion is along the same axis as the propagating wave, the waves are longitudinal. Particles move away from then back towards the vibrating source, creating areas of compression (high pressure) and areas of rarefaction (low pressure). As the motion is transferred from one particle to the next, the sound propagates away from the sound source. Wavelength is the distance from one pressure peak to the next. Frequency is the number of waves passing per unit time (Hz). Sound velocity (not to be confused with particle velocity) is the impedance is loosely equivalent to the resistance of a medium to the passage of sound waves (technically it is the ratio of acoustic pressure to particle velocity). A high impedance means that acoustic particle velocity is small for a given pressure (low impedance the opposite). When a sound strikes a boundary between media of different impedances, both reflection and refraction, and a transfer of energy can occur. The intensity of the reflection is a function of the intensity of the sound wave and the impedances of the two media. Two key factors in determining the potential for damage due to a sound source are the intensity of the sound wave and the impedance difference between the two media (impedance mis-match). The bodies of the vast majority of organisms in the ocean (particularly phytoplankton and zooplankton) have similar sound impedence values to that of seawater. As a result, the potential for sound damage is low; organisms are effectively transparent to the sound – it passes through them without transferring damage-causing energy. Due to the considerations above, we have undertaken a detailed analysis of species which met the following criteria: 1) Is the species capable of being physically affected by LFS? Are acoustic impedence mis-matches large enough to enable LFS to have a physical affect or allow the species to sense LFS? 2) Does the proposed SURTASS LFA geographical sphere of acoustic influence overlap the distribution of the species? Species that did not meet the above criteria were excluded from consideration. For example, phytoplankton and zooplankton species lack acoustic impedance mis-matches at low frequencies to expect them to be physically affected SURTASS LFA. Vertebrates are the organisms that fit these criteria and we have accordingly focused our analysis of the affected environment on these vertebrate groups in the world’s oceans: fishes, reptiles, seabirds, pinnipeds, cetaceans, pinnipeds, mustelids, sirenians (Table 1).

Automated 3D Vision Tracking for Project Control Support

On-site tracking in open construction sites is often difficult because of the large amounts of items that are present and need to be tracked. Additionally, the amounts of occlusions/obstructions present create a highly complex tracking environment. Existing tracking methods are based mainly on Radio Frequency technologies, including Global Positioning Systems (GPS), Radio Frequency Identification (RFID), Bluetooth and Wireless Fidelity (Wi-Fi, Ultra-Wideband, etc). These methods require considerable amounts of pre-processing time since they need to manually deploy tags and keep record of the items they are placed on. In construction sites with numerous entities, tags installation, maintenance and decommissioning become an issue since it increases the cost and time needed to implement these tracking methods. This paper presents a novel method for open site tracking with construction cameras based on machine vision. According to this method, video feed is collected from on site video cameras, and the user selects the entity he wishes to track. The entity is tracked in each video using 2D vision tracking. Epipolar geometry is then used to calculate the depth of the marked area to provide the 3D location of the entity. This method addresses the limitations of radio frequency methods by being unobtrusive and using inexpensive, and easy to deploy equipment. The method has been implemented in a C++ prototype and preliminary results indicate its effectiveness

Toward a comprehensive care of HIV patients: Finding a strategy to detect depression in a Spanish HIV cohort

Depression is a common but frequently undiagnosed feature in individuals with HIV infection. To find a strategy to detect depression in a non-specialized clinical setting, the overall performance of the Hospital Anxiety and Depression Scale (HADS) and the depression identification questions proposed by the European AIDS Clinical Society (EACS) guidelines were assessed in a descriptive cross-sectional study of 113 patients with HIV infection. The clinician asked the two screening questions that were proposed under the EACS guidelines and requested patients to complete the HADS. A psychiatrist or psychologist administered semi-structured clinical interviews to yield psychiatric diagnoses of depression (gold standard). A receiver operating characteristic (ROC) analysis for the HADS-Depression (HADS-D) subscale indicated that the best sensitivity and specificity were obtained between the cut-off points of 5 and 8, and the ROC curve for the HADS-Total (HADS-T) indicated that the best cut-off points were between 12 and 14. There were no statistically significant differences in the correlations of the EACS (considering positive responses to one [A] or both questions [B]), the HADS-D ≥ 8 or the HADS-T ≥ 12 with the gold standard. The study concludes that both approaches (the two EACS questions and the HADS-D subscale) are appropriate depression-screening methods in HIV population. We believe that using the EACS-B and the HADS-D subscale in a two-step approach allows for rapid, assumable and accurate clinical diagnosis in non-psychiatric hospital settings.
