A epistemologia, o documentario e o papagaio : elementos para analise de documentarios da vida selvagem / The epistemiology, the documentary and the parrot : elements for the analysis of the documentaries of wild life

Daniel, Taunay 13 August 2018 (has links)
Orientador: Jacques Marie Edme Vielliard / Anexo 1 DVD / Tese (doutorado) - Universidade Estadual de Campinas, Instituto de Artes / Made available in DSpace on 2018-08-13T17:26:46Z (GMT). No. of bitstreams: 1 Daniel_Taunay_D.pdf: 1625129 bytes, checksum: d2674bb5372164b9eac878bef74bf568 (MD5) Previous issue date: 2009 / Resumo: Esta tese é uma reflexão sobre a possibilidade de se produzir documentários (cinema ou vídeo) perfeitamente fiéis e objetivos em relação à realidade que eles pretendem representar. O foco principal é o documentário de vida selvagem, que tem características específicas muito marcantes que o diferencia nitidamente dos demais tipos de documentários. A linha de argumentação da tese tem como base de sustentação teórica e prática quatro elementos: a) os resultados de uma pesquisa de campo realizada com o objetivo de compreender o comportamento do papagaio-de-peito-roxo Amazona vinacea em seu habitat natural para, em seguida, planejar e produzir um documentário sobre esse animal; b) uma reflexão sobre a epistemologia em geral, com ênfase na questão da possibilidade de haver objetividade no conhecimento; c) uma reflexão sobre a possibilidade de haver objetividade nas imagens registradas através dos dispositivos técnicos criados para esse fim (câmeras fotográficas e cinematográficas); d) uma análise da realização do próprio documentário. A tese defende a existência de uma "matriz do pensamento", criada e sedimentada no decurso da história do mundo ocidental, que nos faz crer que a objetividade pura é possível e desejável e que o conhecimento legítimo e aceitável é somente aquele que é independente da subjetividade do indivíduo que o produz. Procura também mostrar como essa matriz é insustentável, sobretudo em relação aos documentários audiovisuais onde a objetividade e a verdade tornam-se aspirações inadequadas. / Abstract: This paper is a reflection over the possibility to produce objective documentaries (cinema or video), strictly loyal to the reality they mean to represent. The main focus is the documentary of wild life that has specific and very remarkable characteristics, which makes it clearly different from the other kinds of documentaries. The argument line of the paper has four elements as its theoretical and practical basis of support : a) the outcome of a field research carried out with the objective of understanding the behavior of Vinaceous Parrot Amazona vinacea in its natural habitat, and then plan and produce a documentary on this animal; b) a reflection over epistemology in general, with emphasis on the possibility of having objectivity in knowledge; c) a reflection over the possibility of having objectivity in the registered images through technical devices created for this purpose (photographic and cinematographic cameras); d) an analysis of the achievement of the documentary itself. The paper defends the existence of a "matrix of the thought" created and deeply rooted throughout the history of western world, that makes us believe that sheer objectivity is possible and desirable and that authentic and acceptable knowledge is just the one that is independent of the subjectivity of the individual who produces it. It also tries to show how unsustainable this matrix is, especially towards audiovisual documentaries, where objectivity and truth become inadequate aspirations. / Doutorado / Doutor em Multimeios

Vizuální aspekty individuálního rozpoznávání u papoušků šedých / Visual aspects of individual recognition in grey parrots

Prikrylová, Katarína January 2018 (has links)
This diploma thesis is focused on research of individual recognition in African grey parrots based on visual cues from stimulus card made from photographs of familiar conspecifics, specifically on testing the significance of selected visual features. Theoretical part of the thesis deals with the general individual recognition ability followed by specifics of this ability in humans, non-human primates and birds including African grey parrot. Great attention is paid specifically to the individual recognition ability in humans, since it is the aim of this thesis to interpret the results of hypotheses testing comparatively. In order to test the hypotheses seven modifications of conspecifics' photographs were created. Experiment employed matching-to- sample as method, subjects were three African grey parrots. Findings were to a large extent in accordance with findings of analogical studies that used human subjects. Results imply, that visual information in African grey parrot is processed holistically, with structure and pigmentation of feathers on the abdominal part of the parrot having most likely the highest significance for successful individual recognition of a familiar conspecific. Key words: individual recognition, African grey parrot, comparative cognition, visual recognition

Ontogeneze vokalizace papoušků šedých ve srovnání s člověkem / Vocal ontogenesis in grey parrots in comparison to humans

Roubalová, Tereza January 2016 (has links)
Human speech is considered to be unique means of communication. The beginnings of human vocalization, which develops into the speech, however, have some patterns or principles which can also be found in animal communication. It has been discovered that there are similarities between humans and animals in terms of social organization, neural control, cognition and function of vocal signals. Moreover, it seems that birds, parrots specifically, have closer parallels with humans in these respects than with other primates. Vocal ontogeny was, however, at least in parrots, investigated only marginally. Therefore it has become the subject of this study. African grey parrots (Psittacus erithacus) show a wide range of cognitive abilities and are thus suitable species for comparison with humans. The aim of this study was to map the early vocal development of African grey parrots until age of 11 weeks. Then it was possible to compare it theoretically with the early vocal development of children. The repertoire was mapped using video recordings of four fledglings of feral African grey parrots, which are in possession of FHS UK Prague. The recordings were analysed acoustically and visually with audio software Sound Forge Pro 11 and Sound Forge Audio Studio 10. After identifying the repertoire we used stage...

Red-Tailed Hawk Home Range, Habitat Use, and Activity Patterns in North-Central Puerto Rico

Llerandi-Roman, Ivan C 13 May 2006 (has links)
I determined abundance, movement and activity patterns of the Red-tailed Hawk (Buteo jamaicensis jamaicensis, RTHA) in Río Abajo Forest, Puerto Rico and surrounding lands during 2003-2004. Captive-reared Puerto Rican Parrots (Amazona vittata, PRPA) are scheduled for release in Rio Abajo Forest in 2006. Annual density of RTHAs (0.90 RTHAs/km2) was similar to the Caribbean National Forest (CNF; 1.29 RTHAs/ km2). RTHAs annual survival was high (0.89), and birds maintained compressed territories around the Rio Abajo Forest. Home ranges were 91% smaller than estimates reported for CNF, yet similar to those in North America. Approximately 98.3% of RTHA locations occurred outside the Río Abajo Forest boundaries. RTHAs exhibited random macrohabitat use patterns in north-central Puerto Rico. However, within their home ranges, RTHAs selected fragmented habitats with high patch and edge density, and avoided large tracts of dense closed canopy forest. Encounters between RTHAs and PRPAs may increase as parrots venture beyond the boundaries of Rio Abajo Forest.

Papagaios ao espelho / Parrots in the mirror

Natálio, Rita 13 March 2015 (has links)
Made available in DSpace on 2016-04-28T20:39:00Z (GMT). No. of bitstreams: 1 Rita Natalio.pdf: 1543881 bytes, checksum: ae69630225c03cbdf7bf9cc3fe0b719d (MD5) Previous issue date: 2015-03-13 / Fundação Calouste Gulbenkian / In this work, we will start from the imitation theories of the nineteenth-century French sociologist Gabriel Tarde, and the revision of these theories by the Italian philosopher Maurizio Lazzarato. These authors will allow us to think the contemporary processes of subjectivity, in which appears a specific dynamic between imitation and invention on individual life and that, in turn, go hand in hand with neoliberal capitalism dynamics and its incessant deterritorializations. Today, contemporary individuals quickly mobilize their imitations and inventions, their opinions replicate on a large scale and they are driven by the belief in the possibility of interfering, divert, sculpting, modeling and even reverse the direction of their own lives. Imitation and invention can be seen as tools of social construction. Furthermore, in the case of virality and contagion of ideas through social networking on the Internet or analog networks of consumption and influence, a bestial force of imitation is set up that seeks a global spread, a force whose power is extra-individual and allows us to consider subjects beyond self-contained units. To think this theme, we will establish our research in dialogue with other authors and examples from contemporary art to internet examples and, between chapters of the work, we will propose small textual shortcircuits that break the linearity of reasoning. These short-circuits can, in some cases, challenge the conventions of academic text, but they are mainly an experiment on the relationship between invention and imitation in the creation of my own voice / Neste trabalho, partimos das teorias da imitação do sociólogo francês do século XIX Gabriel Tarde, e da sua revisão, já no século XXI, pelo filósofo italiano Maurizio Lazzarato. Esses autores permitem-nos pensar os processos de subjetivação contemporâneos como processos onde se explicita uma dinâmica específica entre imitação e invenção na vida individual que, por sua vez, andam lado a lado com a dinâmica do capitalismo neoliberal e das suas desterritorializações incessantes. Hoje, os indivíduos contemporâneos mobilizam velozmente as suas imitações e invenções, replicam opiniões em larga escala, movidos pela crença na possibilidade de interferir, desviar, esculpir, modelar e até reverter o sentido das suas vidas. Imitação e invenção podem ser vistas como ferramentas de construção social. Para além disso, no caso da viralidade e do contágio de ideias por via de redes sociais na internet ou de redes analógicas de consumo e influência, instala-se uma força bestial de imitação que busca uma propagação planetária, cuja potência é extra-individual e permite pensar o sujeito para além de unidades estanques. Para pensar esta temática, situaremos a nossa pesquisa em diálogo com outros autores e exemplos, deste a arte contemporânea a exemplos retirados da internet, e entre os capítulos que compõem o trabalho, propomos pequenos curto-circuitos textuais na linearidade do raciocínio. Estes curto-circuitos poderão em alguns casos desafiar as convenções do texto académico, mas são sobretudo um experimento sobre a relação entre invenção e imitação na criação de uma voz própria

Hnízdní chování amazoňana pomoučeného (\kur{Amazona farinosa virenticeps}) v přírodě / Nesting behavior of Mealy Amazon (\kur{Amazona farinosa virenticeps}) in the wild

JEŘÁBEK, Zdeněk January 2016 (has links)
The purpose of this study was observing the Mealy Parrot (Amazona farinose virenticeps) in the open air nature, also the study found out their eating and nesting habits. Description of behavior in their natural environment and a description of the habitat in the study area. Monitoring, which took place at the census was made 3 weeks in September 2015. Other investigations in which observation was focused on finding nesting cavities and bird watching in the stream and this was performed three weeks in February 2016. Observation was carried out in Costa Rica on the southeast by the Caribbean Sea in the nature reserve Gandoca Manzanillo. Part of the observations was the liner census of Mealy Parrots with the use of the Passau methods to chart a path along the road leading from the village of Manzanillo to Puerto Vijejo. Length of the strip to the census was fixed at 2.1km about the width of 250m. At the counting was found out how Mealy Parrots was fed and what type of food. Also there was observe at what time Mealy Parrots swoop for food, and what trees were occupying them and in which part of tree crowns they were sitting in. Other research showed their behavior in the presence of other birds and other animals and how they were behaving in danger of predators. In another part of observing, that took place in February 2016 was searched two nests in tree hollows (Manilkara zapota) and (Pterocarpus officinalis). Only in one of the nesting cavity was found one egg, which was measured.

Referenční vokalizace papouška žako kongo (Psittacus erithacus) / Reference vocalization in African grey parrot (Psittacus erithacus)

Brojerová, Jana January 2013 (has links)
The ability to communicate referentially has been historically viewed as being uniquelly human. However, with the increasing amount of studies discussing the communicative faculty of animals in the context of the evolution of human language, there is now growing evidence that this ability is present in many animal species, too. Although we know a lot about mimetic abilities of domesticated African grey parrots' (Psittacus erithacus) and their competence to use human words in a referential way, we know very little about the elements of referentiality in their natural vocalization. Our goal in this work was to find, whether and in which context is functionally referential vocalization in this species of birds present. We were determining its presence by the experiment, in which we have exposed four captured African grey parrot, in the ownership of FHS UK Prague, to stimuli that in other animal species usually elicit functionally referential vocalization: predators and prefered type of food. We analysed the behaviour and vocalizations of the tested birds by analytic softwares Interact, respectively Soundforge 0.8. We find out, that despite the fact that birds reaponded to our experimental objects appropriatelly (i.e. "predators" caused more fear and the like), they give the major amout of...

Estudo comparativo de métodos bioquímicos, perfil de susceptibilidade aos antimicrobianos e método molecular para a caracterização fenotípica e genotípica de bactérias ácido-láticas isoladas da microbiota fecal de Papagaios-verdadeiros (Amazona aestiva) no Brasil / Comparative study of biochemical tests, microbial susceptibility profiling and molecular method for phenotypic and genotypic characterization of acid-latic bacteria isolated from fecal microbiota of Blue-fronted Amazon Parrots (Amazona aestiva) from Brazil

Frazão, Luciana Allegretti 14 April 2014 (has links)
A microbiota do trato gastrointestinal dos psitacídeos é composta por bactérias Gram-positivas, entre elas as bactérias ácido láticas. Porém, há poucos estudos na literatura descrevendo a microbiota do trato gastrointestinal dessas aves. O objetivo deste estudo foi identificar e caracterizar fenotipicamente e genotipicamente, por três diferentes métodos, as bactérias ácido láticas isoladas da microbiota fecal de papagaios verdadeiros. Um total de 80 amostras bacterianas foram estudadas, sendo que 31 amostras eram provenientes da microbiota fecal de papagaios-verdadeiros de vida livre e 49 amostras eram de papagaios-verdadeiros de cativeiro. Foram realizadas provas bioquímicas convencionais, automatizadas (Vitek 2) e o sequenciamento completo do gene 16S rRNA e realizada a análise comparativa dos resultados. Das 80 amostras analisadas, em 40 (50%) destas foram identificadas as espécies, pois apresentaram concordância de identificação em pelo menos dois métodos, e as demais 40 amostras (50%) não apresentaram concordância entre os testes, não sendo possível definir a espécie. As espécies identificadas foram: Enterococcus avium (02 amostras), Enterococcus faecium (03 amostras), Enterococcus faecalis (15 amostras), Enterococcus hirae (15 amostras), Lactococcus lactis (02 amostras) e Staphylococcus warneri (02 amostras). Dentre as amostras identificadas, sete (07) amostras apresentaram concordância no resultado nas três técnicas analisadas, trinta e uma (31) amostras apresentaram concordância pelo bioquímico automatizado e pelo sequenciamento do gene 16S rRNA, e apenas duas (02) amostras apresentaram concordância pelo bioquímico convencional e pelo sequenciamento de DNA. A similaridade de utilização de substratos pelas cepas foi definida em treze (13) amostras, nas demais amostras estudadas houve uma diferença no consumo de substratos nas provas bioquímicas. O perfil de resistência a antimicrobianos evidenciou resistência em onze (11) amostras, quatro (04) a benzilpenicilina, quatro (04) a eritromicina, duas (02) a gentamicina e uma (01) a estreptomicina. A análise filogenética baseada no coeficiente de Neighbor-Join para comparar a similaridade entre as sequencias geradas pelo sequenciamento do gene 16S rRNA, mostrou uma tendência de agrupamento bacteriano de acordo com o local de onde as aves eram provenientes. Verificou-se que a identificação através do teste bioquímico convencional apresentou resultados inconsistentes quando comparados com o teste bioquímico automatizado e com o sequenciamento de DNA. Por sua vez, a técnica do sequenciamento genético demonstrou uma elevada confiabilidade nos resultados obtidos; sugerindo-se a utilização deste como teste de eleição e também como teste complementar as provas bioquímicas, para assim diminuir a probabilidade de erro de identificação bacteriana de bactérias ácido láticas em papagaios. / Gastrointestinal microbiota of pscittacines main consists largely of Gram-positive bacteria, including acid-latic bacteria. However, the literature presents very few reports on profiling the gastrointestinal microbiota of these birds. The aim of this study was to identify and to characterize phenotypicly and genotypicly acid-latic bacteria isolated from fecal microbiota of Blue-fronted Amazon Parrots. For such, three different methods were used on eighty bacterial strains. Thirty-one fecal samples were collected from free-living Blue-fronted Amazon Parrots, while fourty-nine were from captive birds. Traditional biochemical tests, automated biochemical test (Vitek 2) and complete gene sequencing of 16S rRNA were performed. Results of these three methods were compared. Forty samples (50%) had agreement between at least two of the three methods, and bacterial species identification was confirmed, while strains from the remaining 40 samples were not identified, once agreement between atleast two methods was not found. The species identified were: Enterococcus avium (02 samples), Enterococcus faecium (03 samples), Enterococcus faecalis (15 samples), Enterococcus hirae (15 samples), Lactococcus lactis (02 samples) and Staphylococcus warneri (02 samples). Agreement between the three methods was observed in seven samples. Thirty-one samples presented agreement between automated biochemical tests and sequencing of the 16S rRNA gene. Only two samples presented agreement between tradional biochemical tests and gene sequencing. Similarities of substract consumed by strains in both traditional and automated biochemical tests were observed in thirteen samples, while the other samples presented some difference in substracts utilization. Antimicrobial resistance profile showed that eleven samples were resistant to some antibiotic. Four were resistant to benzilpenicilin, four to erythromycin, two to gentamicin and one to estreptomycin. The phylogenetic test based on Neighbor-Join coefficient, which compares the similarity between 16S rRNA sequences, showed a trend for grouping of strains according to the geographical origin of each bird. However, species identification using traditional biochemical tests showed to be inconsistent when compared to automated biochemical tests and gene sequencing results. On the other hand, genetic sequencing technique results showed to be highly reliable. Thus, this method should be used both as gold standard and as complementary to the biochemical tests for acid-latic bacteria identification in Blue-fronted Amazon Parrots gastrointestinal microbiota.
