Opening movements in Ophuls: Caught (and Madame de …)

This audiovisual essay was created at the wonderful NEH-funded workshop in videographic criticism at Middlebury College, ‘Scholarship in Sound and Image’. The essay provides an analysis of the orchestration of long takes and camera movement in the opening of Caught (Ophuls, 1949), and develops a comparison with the opening of Madame de… (Ophuls, 1953 – U.S. release title The Earrings of Madame de…), not least through a series of juxtapositions, which can be directly presented and compared in an audiovisual essay. The openings share a concern with the subjectivity of the female protagonists and our relationship toward it, evoking the women’s experience while balancing this with other kinds of perspective. As has been noted in the critical literature on Ophuls, and on melodramas of passion more generally, such views enable us to perceive the women concerned to be caught in material and ideological frameworks of which they are at best partially aware. Among the interests of this particular comparison, however, is the extent to which the dynamic around female subjectivity is played in relation to luxury goods, imagined, owned or admired. Tensions between on- and off-screen spaces and sounds are critical to the interest of the long takes under discussion. Camera movements subtly inflect the extent to which we are aligned (or otherwise) with the characters and the ways in which their material circumstances are revealed to us.

Light modulates the melanophore response to alpha-MSH in Xenopus laevis: An analysis of the signal transduction crosstalk mechanisms involved

Melanin granule (melanosome) dispersion within Xenopus laevis melanophores is evoked either by light or alpha-MSH. We have previously demonstrated that the initial biochemical steps of light and alpha-MSH signaling are distinct, since the increase in cAMP observed in response to alpha-MSH was not seen after light exposure. cAMP concentrations in response to alpha-MSH were significantly lower in cells pre-exposed to light as compared to the levels in dark-adapted melanophores. Here we demonstrate the presence of an adenylyl cyclase (AC) in the Xenopus melanophore, similar to the mammalian type IX which is inhibited by Ca(2+)-calmodulin-activated phosphatase. This finding supports the hypothesis that the cyclase could be negatively modulated by a light-promoted Ca(2+) increase. In fact, the activity of calcineurin PP2B phosphatase was increased by light, which could result in AC IX inhibition, thus decreasing the response to alpha-MSH. St-Ht31, a disrupting agent of protein kinase A (PKA)-anchoring kinase A protein (AKAP) complex totally blocked the melanosome dispersing response to alpha-MSH, but did not impair the photo-response in Xenopus melanophores. Sequence comparison of a melanophore AKAP partial clone with GenBank sequences showed that the anchoring protein was a gravin-like adaptor previously sequenced from Xenopus non-pigmentary tissues. Co-immunoprecipitation of Xenopus AKAP and the catalytic subunit of PKA demonstrated that PKA is associated with AKAP and it is released in the presence of alpha-MSH. We conclude that in X laevis melanophores, AKAP12 (gravin-like) contains a site for binding the inactive PKA thus compartmentalizing PKA signaling and also possesses binding sites for PKC. Light diminishes alpha-MSH-induced increase of cAMP by increasing calcineurin (PP2B) activity, which in turn inhibits adenylyl cyclase type IX, and/or by activating PKC, which phosphorylates the gravin-like molecule, thus destabilizing its binding to the cell membrane.

Coding behavioural data for cladistic analysis: using dynamic homology without parsimony

Many of the controversies around the concept of homology rest on the subjectivity inherent to primary homology propositions. Dynamic homology partially solves this problem, but there has been up to now scant application of it outside of the molecular domain. This is probably because morphological and behavioural characters are rich in properties, connections and qualities, so that there is less space for conflicting character delimitations. Here we present a new method for the direct optimization of behavioural data, a method that relies on the richness of this database to delimit the characters, and on dynamic procedures to establish character state identity. We use between-species congruence in the data matrix and topological stability to choose the best cladogram. We test the methodology using sequences of predatory behaviour in a group of spiders that evolved the highly modified predatory technique of spitting glue onto prey. The cladogram recovered is fully compatible with previous analyses in the literature, and thus the method seems consistent. Besides the advantage of enhanced objectivity in character proposition, the new procedure allows the use of complex, context-dependent behavioural characters in an evolutionary framework, an important step towards the practical integration of the evolutionary and ecological perspectives on diversity.

Machine vision for the automatic classification of images acquired from Non-destructive tests

This project is based on Artificial Intelligence (A.I) and Digital Image processing (I.P) for automatic condition monitoring of sleepers in the railway track. Rail inspection is a very important task in railway maintenance for traffic safety issues and in preventing dangerous situations. Monitoring railway track infrastructure is an important aspect in which the periodical inspection of rail rolling plane is required.Up to the present days the inspection of the railroad is operated manually by trained personnel. A human operator walks along the railway track searching for sleeper anomalies. This monitoring way is not more acceptable for its slowness and subjectivity. Hence, it is desired to automate such intuitive human skills for the development of more robust and reliable testing methods. Images of wooden sleepers have been used as data for my project. The aim of this project is to present a vision based technique for inspecting railway sleepers (wooden planks under the railway track) by automatic interpretation of Non Destructive Test (NDT) data using A.I. techniques in determining the results of inspection.

”Jag tror på något” : Konstruktioner av tro och tilltro

”I believe in something”: Constructions of Beliefs in Sweden Research results are dependent on how social phenomena are conceptualized. In the present article, consequences are discussed of the standardized conceptualization of religiosity as ”church-oriented”. In its place, a multifaceted approach to the phenomenon of religious belief is suggested. This approach was used for an analysis on how eleven Swedish women and men with different religious and spiritual as well as non-religious and atheist affiliation talk about beliefs. The results suggest that beliefs were meaningful because they related to specific perceptions of a Zeitgeist. It was hereafter underlined that belief in ”something” or other brief descriptions of the sacred placed the sacred outside of the individual. Finally, while subjective authority is valued for choosing to believe, this subjectivity seems in part to be dependent on collective dimensions of recognition. The value of choosing beliefs can be conceptualized as a meaningful yet analytically distinct aspect of belief co-existing with descriptions of the sacred. Thus, it is concluded that a multifaceted approach to religious belief may develop our understanding of religion and religiosity in contemporary society

Konsekvenser av rollövertagandet : ”I”, ”me” och individualiteten

Consequences of role taking: the ”I”, the ”me” and individuality This paper analyzes the tendency of taking the ”I” and the ”me” in G. H. Meads theory of role taking as two separate, qualitatively different parts of human personality, the ”I” being of individual origin, the ”me” of social. In the original Meadian sense role taking gives rise to both the ”I” and the ”me”. They are dialectically united rather than dualistically separated aspects. They refer to the joint functional power of the subject, finding itself as an object, mediated by the Other. As a consequence, the link between body and the social world becomes theoretically more stringent, as the body is given its place as a cognitive social object among others, this by contrast to interpretations where the body is left as an object mainly outside the human social experience and as a source of agency sui generis, a conception which is in opposition to Meads. The stress on the ”I”-phase, as related to body and concrete action in combination with its direct relation to the ”me”-phase, actualizes Mead as a forerunner in modern biologic/neurologic research on human perceptual, motivational and intentional capacity.Swedish Mead interpreters are critically analyzed. Interpretations of Charon, Giddens, Joas and Habermas are partly scrutinized. The author defines the conceptual pair in terms of activity, subjectivity, temporal relativity and distance.

Empregado, autônomo e empresário : a tomada de decisão no setor de transporte rodoviário de cargas em São Marcos, RS

São Marcos, no Rio Grande do Sul, caracteriza-se por sua participação no setor do transporte rodoviário de cargas, sendo o município brasileiro com maior número de veículos pesados por habitante. Este trabalho busca identificar os fatores que influenciam a tomada de decisão dentro desse ramo de negócios. Assim, são estudados quatro casos de profissionais da área. Esses indivíduos iniciaram sua trajetória na condição de empregados, passando em seguida para a fase de autônomos. No entanto, apenas dois deles prosperaram, tornando-se empresários; os outros dois retornaram à condição de empregados. O estudo também possibilitou identificar o nível de insatisfação dos empregados do setor na busca de um progresso dentro do mesmo, assim como observar o perfil de competência daqueles que chegam a implantar suas próprias organizações. Dessa forma, é possível formar um paralelo entre as experiências bem-sucedidas e as tentativas frustradas. Os dados foram levantados a partir de uma série de fontes de evidências como entrevistas, registros de arquivos e documentos dos personagens referidos. A análise desses dados leva à interpretação de dois fatores como fundamentais na tomada de decisões dos indivíduos que trabalham no transporte rodoviário de cargas: a intuição e a influência de outras pessoas que cercam os tomadores de decisão. Esses fatores reforçam a idéia da subjetividade dentro do processo administrativo. O trabalho possibilita a formação de um quadro de dados gerais a respeito do setor. Além disso, serve de referencial às atitudes de organizações públicas e privadas, de pessoas ligadas ao ramo e de jovens que pretendem entrar nesse universo de trabalho.

Remoção de óleos emulsificados por flotação por ar dissolvido

Neste trabalho estuda-se o processo de flotação por ar dissolvido (FAD) como método de remoção de óleos emulsificados. Realizou-se uma revisão bibliográfica tanto do processo de flotação como dos fundamentos físico-químicos envolvidos na estabilidade e flotação de emulsões. Foram realizados testes de estabilidade de emulsões, de FAD descontínuos e contínuos, utilizando-se emulsões de 1000 mg/l de Óleo diesel e heptano. Verificou-se a eficiência do sulfato de alumínio e de compostos poliméricos como agentes desestabilizantes. Estudou-se a influência do tipo e concentração dos agentes desestabilizantes, pH da emulsão, do tipo de água e agitação nos testes de estabilidade como também na flotação por ar dissolvido. Os resultados obtidos indicaram a viabilidade técnica da aplicação do processo para a clarificação de efluentes oleosos atingindo valores de turbidez residual satisfatórios (menores que 5 UNT). O sulfato de alumínio mostrou-se mais eficiente como agente desestabilizante de ambas emulsões nos estudos de estabilidade e testes de PAD descontínuos, mas o polímero catiônico C-505 apresentou melhores resultados nos testes de flotação contínuos. O presente trabalho ainda apresenta um estudo de dimensionamento e do custo da unidade de FAD para remoção de óleos emulsificados que leva em consideração os custos de investimentos e de operação da unidade. Verifica-se que o custo total da unidade depende da vazão de alimentação, taxa de recirculação, taxa ar/sólido em massa e concentração inicial de óleos. Conclui-se que para as taxas de ar/sólido usados na indústria (geralmente menores que 0,1) o custo operacional do reagente é o parâmetro determinante do custo total atualizado da unidade. Isto faz com que o custo total atualizado seja essencialmente independente da relação taxa de aplicação - taxa ar/sólido.

O brinquedo simbólico como uma narrativa

A fim de examinar se o brinquedo simbólico organiza-se numa forma narrativa capaz de desvelar a subjetividade da criança, no presente trabalho é estudado o brincar produzido por três crianças, respectivamente a partir de três estudos de caso. Em cada caso é feita, primeiramente, uma comparação entre as situações d brincar e o esquema narrativo de Todorov. Em seguida, o sentido das narrativas é analisado e comparado com o contexto de vida da criança, segundo a metodologia proposta por jung. Ao final, os resultados dos estudos de caso são comparados. Nosso estudo demonstra que o brinquedo simbólico organiza-se como uma narrativa, mas discute o emprego do conceito de narrativa exclusivamente a partir da narratologia. Isto porque o brinquedo simbólico pode, também, se organizar como uma imagem. Neste estudo, também é mostrado e discutido o modo como a subjetividade da criança aparece no brinquedo simbólico.

Escola pública e comunidade : relações em d'obras

Apresentamos neste trabalho um estudo sobre a processualidade das relações da escola pública com a comunidade, enfocando os agenciamentos que operam na constituição de diferentes modos de relação em uma instituição situada na região metropolitana de Porto Alegre. Sob os referenciais de Gilles Deleuze e Félix Guattari, procuramos pensar as relações como acontecimentos, efeitos de sentidos, agenciados coletivamente por instâncias heterogêneas que compõem o real social. Nosso problema se inscreve no âmbito do discurso e da subjetividade, partindo da hipótese de que é possível pensar as relações nas instituições, para além das representações individuais, para além das relações interpessoais, para além do pressuposto da reprodução social. Procuramos articular conhecimentos da Análise de Discurso na vertente Francesa com as discussões empreendidas por Deleuze e Guattari sobre uma Filosofia da Linguagem e uma Teoria da Subjetividade. Utilizamos o recurso cartográfico proposto por estes autores, trabalhando com os discursos produzidos no encontro da escola com a comunidade. Para tal acompanhamos as atividades de uma escola durante um ano, realizando entrevistas, observações, leitura de documentos, participando de reuniões e encontros festivos. Encontramos em nosso estudo algumas dobras das relações da escola com a comunidade, dobras que nos falam da sua complexidade, a qual temos deixado escapar, ao entendermos as relações, marcados pelo modo-indivíduo de subjetivação, que ganhou força desde a modernidade. Nossa cartografia registrou várias dobras, algumas um pouco mais intensas, como a dobra burocrática, a qual impede que outras forças possam ser potencializadas na escola. Procuramos aqui construir um modo de pensar as relações nas instituições, um pensar nas dobras, para regar um pouco o campo da Análise Institucional no âmbito da Psicologia e da Educação.

O jovem administrador

This work was based on the findings obtained from an experimental class program designed for juniors and seniors of EAESP/FGV Business Administration graduation course, as well as the results from questionnaires and interviews carried on with undergraduate students in 1993 and 1994. The main goal was to evaluate the way the students are entering the work market, which has been marked by internal economic crisis and by a transformation process of the worldwide economy. We are looking for the impacts and consequences of these crisis either in the way they are entering the workforce and even in the construction of subjectivity, which has been associated to a notorious individualistic behavior. The work also presents the students ideas about their wishes and aspirations.

Discursos e a construção do "real": um estudo do processo de formação e institucionalização do campo da biotecnologia

Comprehension of the processes of formation of new organizational fields is the main objective that stimulated the theoretical reflection and empirical research that I present in this paper. My intention here is to uphold the potential for the application of seemingly dichotomous perspectives in terms of the objectivity/subjectivity dimension in the comprehension of the objective in question. The contribution of Foucault, with his concept of discourse, is linked to the proposal of critical constructivism represented by Latour and studies of science and technology. Juxtaposing these perspectives, I examined the dynamics of the biotechnological field on the basis of the dialectic of movements of demarcation/circularity, which is basically a simultaneous movement of (dis)construction of the boundaries of a field. The dialectic of demarcation/circularity is made up of the set of relations established between heterogeneous elements ¿ institutions, economic and social processes, behavioral patterns, systems of norms, techniques, types of classification, forms of characterization, in other words it finds ways of emerging in the course of discursive formations. This theoretical proposal ¿ which incorporates an overlooked dimension in institutional analysis, especially in organization studies (power) ¿ has the advantage of contributing to enhancing comprehension of the dynamics of institutionalization. By proposing that the institutional processes arise within discursive fields, the argument put forward is that such processes contribute to the productivity of the power relations in these fields. In empirical terms, I conducted a descriptive and exploratory research directed at the biotechnology sector. The research was based on a historical perspective, since the analysis spans the period from the origins of genetic science (beginning of the 20th century) through to recent developments in biotechnology in the USA (beginning of the 21st century). The USA was chosen as the locus of research, principally due to the fact that structuring of the field of biotechnology originated in that country, subsequently spreading to other countries around the world. Starting from this theoretical and methodological framework, three discursive formations are highlighted: organization, information and network. Each of the discursive formations is characterized by a dominant set of discourses that prepare the ground for the appearance and (trans)formation of the focus-objects under analysis. In this process, organizations appear in at least two ways: as boundary-organizations ¿ which are important for understanding the movement of the approximation of different discursive domains ¿ and as new organizations, which accompany the (trans)formation of new fields, whereby prevailing discourses materialize at a given historical moment and contribute to breathe life into new discourses, which in turn spark off new power relations. Among the conclusions of this work, I would highlight the following: questioning the 'organizational' dimension of the fields; the relationship revealed not only between the discourses and the institutionalized practices, but also with the process of construction of legitimacy; and the redefinition of the concept of organizations, based on new conceptions relating to the limits of the topic, the objectivity/subjectivity, and space/time dichotomy.

A produção de subjetividades em organizações contemporâneas: práticas discursivas e políticas da empregabilidade

The research aimed at analysing the political and discursive practices of the metanarrative of employability in the contemporary organizational field, heading for the understanding of the social and micropolitical devices which happen to produce some especific kinds of subjectivities within organizations. From a post-modern epistemological perspective (Weltanshauung), the research focused on the issues concerning the production of subjectivities in the existing organizational society beyond the traditional theoretical standpoints whose common assumptions are due to the modernist approaches of organizational analysis. A deconstructive theoretical approach was emphasized across the whole text and it was mainly inspired and intellectually based upon Michel Foucault's genealogical démarche. His original conceptualization of power-knowledge relations informed the development of a methodology so as to analyse the discursive practices which determine many of the human resources policies concerning employability. The main thesis presented employability as a grand-device of micropolitical control towards the production of subjectivities whose main operation technologies are: an economic modernizing rhetoric, a moralistic dietetics and an instrumental education. Several discursive fragments from different academicists, journalists and some authors from the managerial litterature were taken into account so as to carefully deconstruct their speeches. This analysis revealed the mechanisms of production of pasteurized, mercantile and erratic subjectivities. Some inquietudes of heuristic nature are featured in the domain of organizational, psychological, sociological and political perspectives heading for new studies.

Sofrimento psíquico nas organizações: um estudo exploratório junto ao corpo médico de um hospital público no município de Niterói

Essa dissertação foi escrita com o objetivo de promover a discussão sobre o sofrimento psíquico no trabalho. Tema atual, presente na vida de todos os trabalhadores, sejam quais forem suas nacionalidades, sexo, raça, faixa etária, nível de escolaridade, enfim, sujeitos possuidores de subjetividade e de desejo. Contudo, muitas vezes o sofrimento é negado pelas organizações produtivas públicas ou privadas. O sofrimento no trabalho é vivido no quotidiano das organizações como uma carga psíquica responsável por doenças físicas e psicológicas, desajustes emocionais, conflitos interpessoais dentro e fora do ambiente de trabalho, vícios, violência familiar e urbana. O polimorfismo do sofrimento aliado a sua negação pelas organizações e sindicatos confunde e envergonha o trabalhador, que passa a vivê-lo de forma individualizada e solitária. A investigação do tema teve como substrato teórico os estudos sobre psicopatologia do trabalho desenvolvidos por Christophe Dejours e seus seguidores. Além da literatura específica, buscou-se recorrer aos estudos da psicanálise e da teoria geral da administração com o objetivo de proporcionar uma ampla análise do fenômeno abordado. Finalmente, foi realizado um estudo exploratório em uma organização pública, o Hospital Getúlio Vargas Filho, com o objetivo de ilustrar o tema, abordando as questões mais significativas a ele relacionadas.

A implantação de uma universidade corporativa no setor público: o estudo de caso da escola de contas e gestão do tribunal de contas do Estado do Rio de Janeiro

The present research comprehends a case study, through which we analyzed the Programa de Implantação da Escola de Contas do Tribunal de Contas do Estado do Rio de Janeiro - Program of Implantation of the School of Public Finance of the Public Finance Court of the State of Rio de Janeiro - as a progressive educational strategy from the model of corporate university, considering the ten key components (steps) identified by Meister (1999) in his research. The qualitative approach has proved the most adequate for this study, as, regarding data interpretation and investigation process, the subjectivity of the researcher was taken into account, since he himself was designated to the Commission of Implantation of the School of Public Finance and is, presently, general Academic Coordinator of the Escola de Contas e Gestão (ECG) - School of Public Finance and Management, the main goal (product) of the mentioned program. As to the results, the study has shown that the Tribunal de Contas do Estado do Rio de Janeiro (TCE-RJ) has not equally emphasized the ten key components (steps) for the success in the construction of a corporate university, but none of them was neglected. Considering the way it presently works, it is also concluded that the ECG is relevant for the actuation of the TCE-RJ, but is not yet as connected to the performance as it should be. Fundamentally, the ECG still has to develop a personnel development system driven by personnel management through competences, performing a diagnosis of the essential organizational competences, mapping the existing ones, identifying the breaches and analyzing which of theses competences may be developed by means of their activities. Likewise, the ECG also needs to develop a methodology to assess the result as well as the impact of its activities. These circumstances, however, will be used to guide future studies and represent a new starting point.
