La participación del espectador y el autor en cuestión : La poética diversa de Edgardo Antonio Vigo

A fines de los '60, mientras gobiernos dictatoriales ejercían la represión sobre la sociedad argentina, la radicalización política y los cuestionamientos a las jerarquías sociales, a la autoridad y a las instituciones emergían con fuerza. En ese contexto el artista Edgardo Antonio Vigo desarrolló una poética centrada en la participación del espectador, partiendo de una ruptura con su estatuto como sujeto pasivo y distante respecto de la obra, y del artista como único autorizado a tomar parte en el proceso creativo. Veremos en este trabajo de qué modo el artista planteó sus definiciones en torno a esos temas a través de escritos teóricos y trabajos artísticos

ENSINO DE LÍNGUA PORTUGUESA E FORMAÇÃO DE PROFESSORES

O ensino de Língua Portuguesa tem, sem dúvida, representado um problema constante para muitos professores da área nas escolas de ensino básico. Alguns professores, diante das constantes e reiteradas críticas ao ensino de língua materna que muito provavelmente ocorram por conta dos resultados pouco satisfatórios das avaliações oficiais sobre o desempenho dos estudantes sentem-se desnorteados sobre o que fazer em sala de aula. Muitas vezes o desnorteio é tal que os professores acabam não fazendo nada que seja significativo para o desenvolvimento comunicativo dos alunos. Esse tema, que não é novo, mas atual, se impõe pela recorrência das discussões e críticas na academia sobre quais são os objetivos do ensino de Língua Portuguesa e a crise que o ensino dessa disciplina atravessa. Em suma, o ensino hodierno de Língua Portuguesa, em nível básico, não tem suprido as exigências que se impõem ao alunado brasileiro que os estudantes, ao concluírem o ensino médio, escrevam, leiam e falem com competência. Que relação esse quadro tem com a formação e a prática dos professores de Língua Portuguesa em sala de aula? Em que medida as Diretrizes Oficiais para o ensino de Língua Portuguesa são utilizadas como referencias para o trabalho em sala de aula? São essas questões que nortearam a pesquisa. Para responder a essas perguntas realizamos uma pesquisa bibliográfica e empírica de viés qualitativo. A pesquisa bibliográfica, fundamentada nos PCNs de Língua Portuguesa, Sírio Possenti, Luiz Carlos Travaglia, Donald Schön, António Nóvoa, entre outros, nos forneceu subsídios teóricos sobre as diretrizes para o ensino de Língua Portuguesa e sobre a formação do professor. Com a pesquisa de campo a intenção foi a de analisarmos o ensino de língua materna. Para tanto, ouvimos 10 professores e 50 alunos da rede pública de ensino do estado de São Paulo, com o objetivo de conhecer as opiniões e impressões desses professores e alunos sobre o ensino de Língua Portuguesa. A análise dos dados revela que os avanços teóricos no campo da Linguística foram parcialmente incorporados pelos professores, ou seja, os docentes, em suas práticas de sala de aula, restringem-se, muitas vezes, a repetir o mesmo ensino a que sempre estiveram habituados. Os resultados desse estudo, ainda que circunscritos a uma dada realidade, apontam para a necessidade de se buscar meios efetivos para que a formação inicial e continuada dos professores de Língua Portuguesa possam contribuir com novas práticas de ensino em sala de aula.

ANÁLISE DAS MUDANÇAS DOS FATORES DETERMINANTES DA ESTRUTURA DE CAPITAL EM FUNÇÃO DO CICLO DE VIDA DAS EMPRESAS BRASILEIRAS SÃO BERNARDO DO CAMPO

As várias teorias acerca da estrutura de capital despertam interesse motivando diversos estudos sobre o assunto sem, no entanto, ter um consenso. Outro tema aparentemente pouco explorado refere-se ao ciclo de vida das empresas e como ele pode influenciar a estrutura de capital. Este estudo teve como objetivo verificar quais determinantes possuem maior relevância no endividamento das empresas e se estes determinantes alteram-se dependendo do ciclo de vida da empresa apoiada pelas teorias Trade Off, Pecking Order e Teoria da Agência. Para alcançar o objetivo deste trabalho foi utilizado análise em painel de efeito fixo sendo a amostra composta por empresas brasileiras de capital aberto, com dados secundários disponíveis na Economática® no período de 2005 a 2013, utilizando-se os setores da BM&FBOVESPA. Como resultado principal destaca-se o mesmo comportamento entre a amostra geral, alto e baixo crescimento pelo endividamento contábil para o determinante Lucratividade apresentando uma relação negativa, e para os determinantes Oportunidade de Crescimento e Tamanho, estes com uma relação positiva. Para os grupos de alto e baixo crescimento alguns determinantes apresentaram resultados diferentes, como a singularidade que resultou significância nestes dois grupos, sendo positiva no baixo crescimento e negativa no alto crescimento, para o valor colateral dos ativos e benefício fiscal não dívida apresentaram significância apenas no grupo de baixo crescimento. Para o endividamento a valor de mercado foi observado significância para o Benefício fiscal não dívida e Singularidade. Este resultado reforça o argumento de que o ciclo de vida influência a estrutura de capital

The development of a regional energy assessment model

Shropshire Energy Team initiated this study to examine consumption and associated emissions in the predominantly rural county of Shropshire. Current use of energy is not sustainable in the long term and there are various approaches to dealing with the environmental problems it creates. Energy planning by a local authority for a sustainable future requires detailed energy consumption and environmental information. This information would enable target setting and the implementation of policies designed to encourage energy efficiency improvements and exploitation of renewable energy resources. This could aid regeneration strategies by providing new employment opportunities. Associated reductions in carbon dioxide and other emissions would help to meet national and international environmental targets. In the absence of this detailed information, the objective was to develop a methodology to assess energy consumption and emissions on a regional basis from 1990 onwards for all local planning authorities. This would enable a more accurate assessment of the relevant issues, such that plans are more appropriate and longer lasting. A first comprehensive set of data has been gathered from a wide range of sources and a strong correlation was found between population and energy consumption for a variety of regions across the UK. In this case the methodology was applied to the county of Shropshire to give, for the first time, estimates of primary fuel consumption, electricity consumption and associated emissions in Shropshire for 1990 to 2025. The estimates provide a suitable baseline for assessing the potential contribution renewable energy could play in meeting electricity demand in the country and in reducing emissions. The assessment indicated that in 1990 total primary fuel consumption was 63,518,018 GJ/y increasing to 119,956,465 GJ/y by 2025. This is associated with emissions of 1,129,626 t/y of carbon in 1990 rising to 1,303,282 t/y by 2025. In 1990, 22,565,713 GJ/y of the primary fuel consumption was used for generating electricity rising to 23,478,050 GJ/y in 2025. If targets to reduce primary fuel consumption are reached, then emissions of carbon would fall to 1,042,626 by 2025, if renewable energy targets were also reached then emissions of carbon would fall to 988,638 t/y by 2025.

Manufacturing technology sourcing practices in the USA

Some companies are heavily reliant on the capabilities of their manufacturing technology for product competitiveness. Likewise, the capabilities of a manufacturing technology are dependent on the sourcing policy that the host company practices. This paper describes research that has explored a wide variety of US companies to understand manufacturing technology sourcing policies and how they have been formed. This research finds that there is a preference amongst the US organizations studied not to become involved with equipment manufacture, though some examples of full integration do occur. These policies are not determined by formalized decision processes, rather they are formed implicitly during technology choice. In this research, factors that influence a technology source have been identified. These drivers are then used to establish a methodology that will help practising managers to form a technology sourcing decision. This methodology takes into account the business demands placed on a technology, along with the characteristics of the host company's supplier base.

Sub-50 fs Yb-doped laser with anomalous-dispersion photonic crystal fiber

We report on the generation of 42 fs pulses at 1 µm in a completely fiber-integrated format, which are, to the best of our knowledge, the shortest from all-fiber-integrated Yb-doped fiber lasers to date. The ring fiber cavity incorporates anomalous-dispersion, solid-core photonic crystal fiber with low birefringence, which acts as a broadband, in-fiber Lyot filter to facilitate mode locking. The oscillator operates in the stretched-pulse regime under slight normal net cavity dispersion. The cavity generates 4.7 ps long pulses with a spectral bandwidth of 58.2 nm, which are dechirped to 42 fs via a grating pair compressor outside of the cavity. Relative intensity noise (RIN) of the laser is characterized, with the integrated RIN found to be 0.026% in the 3 Hz-250 kHz frequency range.

Modification of the B2-type matrix of aluminide diffusion coatings on nickel-base superalloys-bulk aluminide analogues

Pack aluminide coating is a useful method for conferring oxidation resistance on nickel-base superalloys. Nominally, these coatings have a matrix composed of a Ni-Al based B2-type phase (commonly denoted as Β). However, following high-temperature exposure in oxidative envi-ronments, aluminum is depleted from the coating. Aluminum depletion in turn, leads to de-stabilization of the Β phase, resulting in the formation of a characteristic lathlike Β-derivative microstructure. This article presents a transmission electron microscopy study of the formation of the lathlike Β-derivative microstructure using bulk nickel aluminides as model alloys. In the bulk nickel aluminides, the lathlike microstructure has been found to correspond to two distinct components: L10-type martensite and a new Β derivative. The new Β derivative is characterized and the conditions associated with the presence of this feature are identified and compared with those leading to the formation of the L10 martensitic phase. © 1995 The Minerals, Metals & Material Society.

Stability of an Optimal Schedule for a Job-Shop Problem with Two Jobs

The usual assumption that the processing times of the operations are known in advance is the strictest one in scheduling theory. This assumption essentially restricts practical aspects of deterministic scheduling theory since it is not valid for the most processes arising in practice. The paper is devoted to a stability analysis of an optimal schedule, which may help to extend the significance of scheduling theory for decision-making in the real-world applications. The term stability is generally used for the phase of an algorithm, at which an optimal solution of a problem has already been found, and additional calculations are performed in order to study how solution optimality depends on variation of the numerical input data.

Generalized KPCA by adaptive rules in feature space

Principal component analysis (PCA) is well recognized in dimensionality reduction, and kernel PCA (KPCA) has also been proposed in statistical data analysis. However, KPCA fails to detect the nonlinear structure of data well when outliers exist. To reduce this problem, this paper presents a novel algorithm, named iterative robust KPCA (IRKPCA). IRKPCA works well in dealing with outliers, and can be carried out in an iterative manner, which makes it suitable to process incremental input data. As in the traditional robust PCA (RPCA), a binary field is employed for characterizing the outlier process, and the optimization problem is formulated as maximizing marginal distribution of a Gibbs distribution. In this paper, this optimization problem is solved by stochastic gradient descent techniques. In IRKPCA, the outlier process is in a high-dimensional feature space, and therefore kernel trick is used. IRKPCA can be regarded as a kernelized version of RPCA and a robust form of kernel Hebbian algorithm. Experimental results on synthetic data demonstrate the effectiveness of IRKPCA. © 2010 Taylor & Francis.

Profit, fenntarthatóság és etika

A nagy német filozófus, Martin Heidegger szerint a modern technológia sodorja végveszélybe az emberi és természeti létezést. A modern technológia ökológiai és etikai veszélyessége kétségtelen, azonban csak a modern vállalati működés segítségével fejti ki a hatásait. A profit-hajszoló modern vállalatok azok, amelyek veszélyeztetik a természeti ökoszisztémák integritását és biológiai sokféleségét, a helyi közösségek autonómiáját és kultúráját, valamint a jövő generációk életesélyeit. A tanulmányban a profit-maximalizálás kritikáját vázoljuk fel, és a gazdasági racionalitás egy átfogó, ökológiai és etikai értelmezését adjuk. Nem a profit eltörléséről van szó, hanem a kíméletlen profit-hajszolás megregulázásáról. A profit a gazdasági cselekvés jogos és természetes gyümölcse, ha az azt létrehozó tevékenység fenntartható és etikus módon megy végbe.

The relationship of thymulin activity, immune parameters of HIV disease progression and substance use in a cohort of HIV seropositive alcohol and drug users

Zinc is essential for the activity of thymulin, a thymic hormone involved in T-lymphocyte differentiation and activation. Zinc deficiency is widespread in populations with HIV infection, and HIV+ drug users are particularly susceptible to zinc deficiency and immune suppression. This dissertation explored the relationship of zinc-bound active thymulin to plasma zinc, CD4+ and CD8+ cell count, the CD4+/CD8+ ratio, and drug use in HIV-infected drug users. Zinc-bound active thymulin was assessed in plasma of HIV+ drug users who were participating in a 30 month zinc supplementation trial. Plasma from 80 participants at the 12 month visit, and 40 of these same participants, randomly selected, at the baseline visit were assessed for zinc-bound active thymulin levels using a modification of the rosette inhibition assay. Thymulin activity was directly associated with CD4+ cell count (β = 0.127, p = 0.002) and inversely associated with cocaine use (β = −0.908, p = 0.026; R2 = 0.188, p = 0.019) independent of HIV viral load, age, gender and antiretroviral use. An increase in thymulin activity was 1.4 times more likely when CD4+ cell count increased (OR = 1.402, 95%CI: 1.006–1.956), independent of change in viral load, antiretroviral use, and age. Participants who used cocaine consistently, were 7.6 times less likely to have an increase in thymulin activity (OR = 0.133, 95%CI: 0.017–1.061). There was a direct correlation between change in plasma zinc and change in zinc-bound active thymulin (r = 0.243, p = 0.13). Analysis of CD4+ cell count decline in 222 participants in the zinc supplementation trial across the 30 months showed that both crack cocaine use and heavy alcohol use accelerated CD4+ cell count decline. Thymulin activity is directly associated with HIV disease progression, measured by CD4+ cell count, and is depressed with cocaine use independent of antiretroviral use and HIV viral load. Cocaine and heavy alcohol accelerate CD4+ cell count decline. The effect of cocaine on thymic output requires further evaluation as a mechanism for the association of cocaine use with faster HIV disease progression.
