Cuerpos cosificados: una lectura de Herencia de Clorinda Matto de Turner (Estudios)

En este ensayo la teoría de Karl Marx, sobre el bien de consumo y sobre los valores de uso e intercambio, así como también las reflexiones de la feminista De Luce Irigaray, expuestas en “Women on the Market”, nos ayudan a analizar las relaciones sociales en el siglo XIX y a ver al espacio de Lima como un gran mercado, en donde la sociedad burguesa hace uso de los objetos de moda para aparentar una posición social alta. En este espacio urbano, que aparece recargado de objetos de compra y venta, Margarita y Lucía se presentan como compradoras, pero no solo de objetos sino también de cuerpos, de esta manera, Margarita es un cuerpo exhibido en la gran vitrina que es Lima, en donde la clase alta debe observarla, aceptarla o rechazarla. Ella es mestiza, pero su origen no interesa, sino cómo luce su cuerpo y qué ostenta o aparenta tener, con lo cual ella, finalmente, consigue marido. En este ensayo se ve cómo el cuerpo femenino tiene un valor de intercambio, pues al ostentar puede aspirar a un candidato de clase alta también, sin embargo, en esta novela todos los cuerpos femeninos y masculinos llegan a tener un valor de uso o intercambio que no se mide por lo que se es, sino por lo que se aparenta por medio de la moda y sus lujos.

Fighting strategies in two species of fig wasp

Although theory exists concerning the types of strategies that should be used in contests over resources, empirical work explicitly testing its predictions is relatively rare. We investigated male fighting strategies in two nonpollinating. g wasp species associated with Ficus rubiginosa figs. In Sycoscapter sp. A, males did not assess each other before or during fights over mating opportunities. Instead,fights continued until the loser reached an energetic cost threshold that was positively correlated with its body size (fighting ability) and retreated. In Philotrypesis sp. B, pre fight assessment was indicated, with males attacking competitively inferior rivals to remove them from the competitor pool ( they then continued to do so until they reached a cost threshold that was again positively correlated with body size). Using data on species ecology, we discuss our findings with respect to theory on when different fighting strategies should evolve. We argue that the type of strategy used by a. g wasp species is determined by its relative benefits in terms of inclusive fitness. (c) 2008 The Association for the Study of Animal Behaviour.

The factor structure of the Edinburgh postnatal depression scale in a South African peri-urban settlement

The factor structure of the Edinburgh Postnatal Depression scale (EPDS) and similar instruments have received little attention in the literature. The researchers set out to investigate the construct validity and reliability of the EPDS amongst impoverished South African women. The EPDS was translated into isiXhosa (using Brislin's back translation method) and administered by trained interviewers to 147 women in Khayelitsha, South Africa. Responses were subjected to maximum likelihood confirmatory factor analysis. A single factor structure was found, consistent with the theory on which the EPDS was based. Internal consistency was satisfactory (a = 0.89).

Career journeys and turning points of senior female managers in small construction firms

There is under-representation of senior female managers within small construction firms in the United Kingdom. The position is denying the sector a valuable pool of labour to address acute knowledge and skill shortages. Grounded theory on the career progression of senior female managers in these firms is developed from biographical interviews. First, a turning point model which distinguishes the interplay between human agency and work/home structure is given. Second, four career development phases are identified. The career journeys are characterized by ad hoc decisions and opportunities which were not influenced by external policies aimed at improving the representation of women in construction. Third, the 'hidden', but potentially significant, contribution of women-owned small construction firms is noted. The key challenge for policy and practice is to balance these external approaches with recognition of the 'inside out' reality of the 'lived experiences' of female managers. To progress this agenda there is a need for: appropriate longitudinal statistical data to quantify the scale of senior female managers and owners of small construction firms over time; and, social construction and gendered organizational analysis research to develop a general discourse on gender difference with these firms.

Synthesis of infrared filters for use in spaceflight systems

Progress is reported in the development of a new synthesis method for the design of filters and coatings for use in spaceborne infrared optics. This method uses the Golden Section optimization routine to make a search, using designated dielectric thin film combinations, for the coating design which fulfills the required spectral requirements. The final design is that which uses the least number of layers for the given thin film materials in the starting design. This synthesis method has successfully been used to design broadband anti-reflection coatings on infrared substrates. The 6 micrometers to 18 micrometers anti-reflection coating for the germanium optics of the HIRDLS instrument, to be flown on the NASA EOS-Chem satellite, is given as an example. By correctly defining the target function to describe any specific type of filter in the optimization part of the method, this synthesis method may be used to design general filters for use in spaceborne infrared optics.

Interpretation bias and anxiety in childhood: stability, specificity and longitudinal associations

Background: Biases in the interpretation of ambiguous material are central to cognitive models of anxiety; however, understanding of the association between interpretation and anxiety in childhood is limited. To address this, a prospective investigation of the stability and specificity of anxious cognitions and anxiety and the relationship between these factors was conducted. Method: Sixty-five children (10–11 years) from a community sample completed measures of self-reported anxiety, depression, and conduct problems, and responded to ambiguous stories at three time points over one-year. Results: Individual differences in biases in interpretation of ambiguity (specifically “anticipated distress” and “threat interpretation”) were stable over time. Furthermore, anticipated distress and threat interpretation were specifically associated with anxiety symptoms. Distress anticipation predicted change in anxiety symptoms over time. In contrast, anxiety scores predicted change in threat interpretation over time. Conclusions: The results suggest that different cognitive constructs may show different longitudinal links with anxiety. These preliminary findings extend research and theory on anxious cognitions and their link with anxiety in children, and suggest that these cognitive processes may be valuable targets for assessment and intervention.

Characterizing intuition in information systems research

The study of intuition is an emerging area of research in psychology, social sciences, and business studies. It is increasingly of interest to the study of management, for example in decision-making as a counterpoint to structured approaches. Recently work has been undertaken to conceptualize a construct for the intuitive nature of technology. However to-date there is no common under-standing of the term intuition in information systems (IS) research. This paper extends the study of intuition in IS research by using exploratory research to cate-gorize the use of the word “intuition” and related terms in papers published in two prominent IS journals over a ten year period. The entire text of MIS Quarterly and Information Systems Research was reviewed for the years 1999 through 2008 using searchable PDF versions of these publications. As far as could be deter-mined, this is the first application of this approach in the analysis of the text of IS academic journals. The use of the word “intuition” and related terms was catego-rized using coding consistent with Grounded Theory. The focus of this research was on the first two stages of Grounded Theory analysis - the development of codes and constructs. Saturation of coding was not reached: an extended review of these publications would be required to enable theory development. Over 400 incidents of the use of “intuition”, and related terms were found in the articles reviewed. The most prominent use of the term of “intuition” was coded as “Intui-tion as Authority” in which intuition was used to validate a research objective or finding; representing approximately 37 per cent of codes assigned. The second most common coding occurred in research articles with mathematical analysis, representing about 19 per cent of the codes assigned, for example where a ma-thematical formulation or result was “intuitive”. The possibly most impactful use of the term “intuition” was “Intuition as Outcome”, representing approximately 7 per cent of all coding, which characterized research results as adding to the intui-tive understanding of a research topic or phenomena. This research contributes to a greater theoretical understanding of intuition enabling insight into the use of intuition, and the eventual development of a theory on the use of intuition in academic IS research publications. It also provides potential benefits to practi-tioners by providing insight into and validation of the use of intuition in IS man-agement. Research directions include the creation of reflective and/or formative constructs for intuition in information systems research.

Sobre la toma de decisiones economicas bajo incertidumbre

In this article we review the evolution of economic theory on decision making under uncertainty. After a brief reference to Expected Utility Theory, we refer to behavioural paradoxes, forcing the theorists to adopt less restrictive approaches, allowing us to explain a broader spectrum of phenomena. The complexity entailed in the new theories requires a multidimensional description of human attitudes towards risk. Nevertheless, measurement of this attitudes has not followed the desired path, with most elicitation methods remaining uni-dimensional.

Environmental agreements as a Hawk-Dove game with confirmed proposals

This paper aims at two different contributions to the literature on international environmental agreements. First, we model environmental agreements as a generic situation, characterized as a Hawk-Dove game with multiple asymmetric equilibria. Second, the article applies the theory on non-cooperative games with confirmed proposals, based on an alternating proposals bargaining protocol, as a way of overcoming the usual problems of coordination and bargaining failures in environmental agreement games, due to payoff asymmetry and equilibrium multiplicity.

Semilinear parabolic problems in thin domains with a highly oscillatory boundary

In this paper, we study the behavior of the solutions of nonlinear parabolic problems posed in a domain that degenerates into a line segment (thin domain) which has an oscillating boundary. We combine methods from linear homogenization theory for reticulated structures and from the theory on nonlinear dynamics of dissipative systems to obtain the limit problem for the elliptic and parabolic problems and analyze the convergence properties of the solutions and attractors of the evolutionary equations.

Predictions from an anisotropic inflationary era

This paper investigates the predictions of an inflationary phase starting from a homogeneous and anisotropic universe of the Bianchi I type. After discussing the evolution of the background spacetime, focusing on the number of e-folds and the isotropization, we solve the perturbation equations and predict the power spectra of the curvature perturbations and gravity waves at the end of inflation. The main features of the early anisotropic phase is (1) a dependence of the spectra on the direction of the modes, (2) a coupling between curvature perturbations and gravity waves and (3) the fact that the two gravity wave polarizations do not share the same spectrum on large scales. All these effects are significant only on large scales and die out on small scales where isotropy is recovered. They depend on a characteristic scale that can, but a priori must not, be tuned to some observable scale. To fix the initial conditions, we propose a procedure that generalizes the one standardly used in inflation but that takes into account the fact that the WKB regime is violated at early times when the shear dominates. We stress that there exist modes that do not satisfy the WKB condition during the shear-dominated regime and for which the amplitude at the end of inflation depends on unknown initial conditions. On such scales, inflation loses its predictability. This study paves the way for the determination of the cosmological signature of a primordial shear, whatever the Bianchi I spacetime. It thus stresses the importance of the WKB regime to draw inflationary predictions and demonstrates that, when the number of e-folds is large enough, the predictions converge toward those of inflation in a Friedmann-Lemaitre spacetime but that they are less robust in the case of an inflationary era with a small number of e-folds.

Talangfabriken : Om organisation av kunskap och kreativitet i skivindustrin

The purpose of this dissertation is to describe, explain and understand how record companies identify and develop new music and new talent. The analysis is carried out on three levels: individual, organizational and sector level. In a record company, this task formally goes to A&R (Artist and Repertoire). This dissertation takes its point of departure in how the capacity for discovering new talent can be understood in terms of knowledge, creativity and competence and how this capacity is affected in the meeting between the record company and the industry. The theoretical framework of the dissertation spans two sociological fields: the sociology of organizations and the sociology of knowledge. While it takes its organizational starting point in the Knowledge Company Approach, it employs a practice-based approach to discuss knowledge. I argue that within the Knowledge company approach there are two contrasting ways to understand knowledge; a distinction is made between knowledge- and creativity-intensive enterprises. The results show that the record industry’s polarized structure can be seen as a result of the Knowledge Company’s typical problems. The A&R’s work is described as including two phases, one intuitive and one analytical. The intuitive assessment is direct, unconscious and without reflection. This ability has been described as "intuition" and "gut feeling". The analytical phase adds analysis and reflection based on knowledge. The results from the interviews with A&R’s reveal the limit of formal and explicit knowledge not only in the choice of music but also in the marketing strategies. The overarching picture is one in which record companies move in a space characterized by tension between dichotomous forces – art and commercialism, creativity and knowledge, culture and economy, chaos and order, but where opposite poles are not mutually exclusive but complementary.

Estruturação e processos isomórficos do campo organizacional de alambiques de cachaça artesanal em Bananal - SP

This work tries to comprehend, throw the prism of the Institutional Theory, the structural process of organizational field of cachaça¿s handicraft producers¿ from a Brazilian countryside region. The role of values and traditions on the determination of the structure and decision making on this industry are analyzed. It is necessary to research historic, economic and social facts, and confront them to the formation of Brazilian society to understand the field¿s formulation. An important aspect of this research is the mapping of isomorphic process and the comparison of the field¿s institutional degree, before and after the changes. It was noticed that the alteration on perception of Cachaça in the national market and the entrance of a new actor oriented by functional rationality are the major reasons for the mimetic changes on this field. As a contribution, this study confirms the applicability of Institutional Theory on analysis of specific fields and shows how this field has structured itself.

Achieving quality in management of development ngos: analysis of four ngos in Rio de Janeiro.

Rio de Janeiro is among the cities with the highest amount of NGOs in the world. However, not all of the projects carried out by the NGOs are equally successful. In this research, I would like to analyze a selection of some of the most well-known social development enterprises operating in Rio, in order to better understand how they operate, what difficulties they face, which factors play the crucial role in achieving peak performance. Moreover, I would like to compare the field research findings with the academic theory on management of social development NGOs, and possibly come up with ideas for further improvements.

Gestão intercultural: a experiência de executivos brasileiros no México

O presente trabalho tem por objetivo levantar quais as dificuldades que os executivos brasileiros, caracterizados por um estilo gerencial brasileiro, enfrentam ao fazer negócios e trabalhar no México. Escolhemos Brasil e México por dois motivos: o primeiro é que atualmente estes dois países representam as duas maiores economias da América Latina, sendo responsáveis por mais de 60% do PIB da região. O segundo é nosso interesse pessoal, devido nossa própria experiência de trabalho, iniciada em 2002 (e que continua acontecendo até o presente momento) quando começamos a interagir com o México no nosso trabalho cotidiano dentro de uma empresa privada. Para alcançar o nosso objetivo primeiramente definimos o que é cultura, cultura nacional, e como ela afeta o estilo gerencial. Estudamos na bibliografia os estilos gerenciais brasileiro e mexicano, e utilizamos o modelo de comparação de estilos gerenciais de Hofstede para identificar as diferenças entre eles, pois acreditamos que as dificuldades se relacionam com as diferenças entre os dois estilos. Posteriormente, fizemos uma pesquisa de campo, entrevistando de forma semi-estruturada sete executivos brasileiros que trabalharam no México para confirmar as diferenças nos estilos gerenciais e levantar quais foram as dificuldades que eles tiveram por conta das mesmas. Finalmente, apresentamos essas diferenças e concluímos que, ainda que os estilos gerenciais de ambos os países sejam próximos – e isso se reflete nos rankings que ambos ocupam nas quatro dimensões de Hofstede – as diferenças trazem sim dificuldades que precisam ser levadas em conta para facilitar a adaptação e o sucesso nos desafios profissionais que os executivos brasileiros venham a empreender no México.
