Biopolítica y gran relato nacional: presencia espectral del mundo aborigen en tres novelas de la selva (Estudios)

Escritas durante la primera mitad del siglo XX, Canaima, La vorágine, y Sangama son tres novelas de la selva en las cuales aparece una representación del mundo indígena del Amazonas o del Orinoco. Se ha repetido que se trataba de novelas progresistas, que encerraban una crítica del sistema social de la época, y más particularmente del genocidio acarreado por la explotación del caucho durante el “ciclo da borracha”. Sin embargo estas ficciones nos proporcionan un enfoque ambiguo de la realidad indígena. Una visión impregnada por las mismas concepciones del siglo XIX que favorecieron los excesos, maltratos y masacres que dichas novelas pretenden denunciar. Este ensayo se propone analizar la matriz científica de estas representaciones, insistiendo en el paradigma racialista decimónico, derivado de la teoría evolucionista y de la ideología del progreso. Los indios de las ficciones se desplazan como fantasmas en un universo mágico, embrujado, o infernal que carece de realidad. Este “flor” romántico es la proyección literaria de una estrategia biopolítica que se da en las sociedades de la época: la cuestión gira en torno a la construcción del pueblo nacional. Los “aparecidos” del espacio novelesco son un momento de unas estrategias discursivas más globales: se trata de construir una homegeneidad nacional a partir de una etnicidad ficticia que requiere el rechazo del “otro atrasado”. El espectro es la huella o el testigo de esta violencia fundadora.

Reproductive conflict delays the recovery of an endangered social species

Evolutionary theory predicts that individuals, in order to increase their relative fitness, can evolve behaviours that are detrimental for the group or population. This mismatch is particularly visible in social organisms. Despite its potential to affect the population dynamics of social animals, this principle has not yet been applied to real-life conservation. Social group structure has been argued to stabilize population dynamics due to the buffering effects of nonreproducing subordinates. However, competition for breeding positions in such species can also interfere with the reproduction of breeding pairs. Seychelles magpie robins, Copsychus sechellarum, live in social groups where subordinate individuals do not breed. Analysis of long-term individual-based data and short-term behavioural observations show that subordinates increase the territorial takeover frequency of established breeders. Such takeovers delay offspring production and decrease territory productivity. Individual-based simulations of the Seychelles magpie robin population parameterized with the long-term data show that this process has significantly postponed the recovery of the species from the Critically Endangered status. Social conflict thus can extend the period of high extinction risk, which we show to have population consequences that should be taken into account in management programmes. This is the first quantitative assessment of the effects of social conflict on conservation.

Climate vs. soil factors in local adaptation of two common plant species

Evolutionary theory suggests that divergent natural selection in heterogeneous environments can result in locally adapted plant genotypes. To understand local adaptation it is important to study the ecological factors responsible for divergent selection. At a continental scale, variation in climate can be important while at a local scale soil properties could also play a role. We designed an experiment aimed to disentangle the role of climate and ( abiotic and biotic) soil properties in local adaptation of two common plant species. A grass (Holcus lanatus) and a legume ( Lotus corniculatus), as well as their local soils, were reciprocally transplanted between three sites across an Atlantic-Continental gradient in Europe and grown in common gardens in either their home soil or foreign soils. Growth and reproductive traits were measured over two growing seasons. In both species, we found significant environmental and genetic effects on most of the growth and reproductive traits and a significant interaction between the two environmental effects of soil and climate. The grass species showed significant home site advantage in most of the fitness components, which indicated adaptation to climate. We found no indication that the grass was adapted to local soil conditions. The legume showed a significant home soil advantage for number of fruits only and thus a weak indication of adaptation to soil and no adaptation to climate. Our results show that the importance of climate and soil factors as drivers of local adaptation is species-dependent. This could be related to differences in interactions between plant species and soil biota.

First steps in experimental cancer evolution

Evolutionary processes play a central role in the development, progression and response to treatment of cancers. The current challenge facing researchers is to harness evolutionary theory to further our understanding of the clinical progression of cancers. Central to this endeavour will be the development of experimental systems and approaches by which theories of cancer evolution can be effectively tested. We argue here that the experimental evolution approach – whereby evolution is observed in real time and which has typically employed microorganisms – can be usefully applied to cancer. This approach allows us to disentangle the ecological causes of natural selection, identify the genetic basis of evolutionary changes and determine their repeatability. Cell cultures used in cancer research share many of the desirable traits that make microorganisms ideal for studying evolution. As such, experimental cancer evolution is feasible and likely to give great insight into the selective pressures driving the evolution of clinically destructive cancer traits. We highlight three areas of evolutionary theory with importance to cancer biology that are amenable to experimental evolution: drug resistance, social evolution and resource competition. Understanding the diversity, persistence and evolution of cancers is vital for treatment and drug development, and an experimental evolution approach could provide strategic directions and focus for future research.

A relação entre confiança interpessoal e compartilhamento de conhecimento tácito

Empresas de negócios, que são constantemente pressionados por inovação, têm na criação de conhecimento organizacional a base para a estratégia de sobrevivência. Muito desse conhecimento acumulado é tácito, encarnado em indivíduos e incorporado pela organização, e que é de difícil articulação. A necessária justificativa de um novo conhecimento torna a sua criação um processo muito frágil. Indivíduos podem sentir-se ameaçados em compartilhar insights, intuição, novas ideias, know-how, habilidades específicas, diante de devastadores mecanismos de controle social como ridículo, difamação e opróbrio, ou pela possibilidade de mau uso de um conhecimento útil e valioso. Por outro lado, com a criança logo ao nascer, e derivado do narcisismo primário, emerge a confiança básica que acompanha o indivíduo ao longo de sua existência, e que, portanto, pode levá-lo a compartilhar seus achados. Esta pesquisa, um ensaio teórico, explorou a relação entre a confiança e compartilhamento de conhecimento tácito nas organizações. Com abordagem multidisciplinar, aderente ao pensamento complexo, incorporou referenciais teóricos advindos de trabalhos de neo-schumpeterianos (Teoria Evolucionária), da sociologia e da psicologia. O percurso metodológico contemplou a busca de artigos em base de dados, leitura de resumos de artigos, busca de autores consagrados na literatura, consulta de autores referenciados nos artigos, leitura e análise de trabalhos selecionados. Mediante análise de conteúdo, que busca identificar o que está sendo dito a respeito do tema, foram criadas as seguintes categorias de análise: inovação, poder, teoria de criação de conhecimento organizacional e confiança humana. Cada uma dessas categorias compôs um capítulo desta dissertação. Embora a escassez de pesquisas empíricas relacionadas ao tema, a análise de conteúdo dos artigos examinados permitiram concluir que a confiança interpessoal mantém relação de poder simétrico entre indivíduos e assim é capaz de acessar o conhecimento tácito enraizado na mente de indivíduos. Dessa forma, com a pesquisa aqui apresentada, espera-se ter contribuído para a literatura e práticas organizacionais relacionadas à gestão de conhecimento. Por fim, foram relatadas limitações no trabalho e sugestões para futuras pesquisas.

Differential-Evolution-Based Optimization of the Dynamic Response for Parallel Operation of Inverters With No Controller Interconnection

In this paper, the use of differential evolution ( DE), a global search technique inspired by evolutionary theory, to find the parameters that are required to achieve optimum dynamic response of parallel operation of inverters with no interconnection among the controllers is proposed. Basically, in order to reach such a goal, the system is modeled in a certain way that the slopes of P-omega and Q-V curves are the parameters to be tuned. Such parameters, when properly tuned, result in system's eigenvalues located in positions that assure the system's stability and oscillation-free dynamic response with minimum settling time. This paper describes the modeling approach and provides an overview of the motivation for the optimization and a description of the DE technique. Simulation and experimental results are also presented, and they show the viability of the proposed method.

Aprender versus ensinar: Charles Sanders Peirce e a universidade americana do final do século XIX

A produção científica e filosófica de Charles Sanders PEIRCE (1839-1914), exigindo como critério para o trabalho intelectual e para a conduta da vida do pensador o absoluto rigor na construção dos conceitos e a estrita verificação experimental, teve por conseqüência desvincular o trabalho científico e filosófico de qualquer função apologética. A afirmação de que todo conhecimento do mundo da experiência e mesmo daquele elaborado pela matemática é intrinsecamente provável e falível se opôs a todo e qualquer dogmatismo e mesmo ao a priori de tradição Kantiana. O interesse pela teoria evolucionista e a coerência inabalável da filosofia e das atitudes de PEIRCE, como professor e pesquisador, encontraram profunda resistência no meio universitário e editorial de seu tempo. Num momento de grave crise na Universidade norte-americana, decorrente das transformações econômicas e políticas ocorridas com a guerra da Secessão (1861-1865), o posicionamento de PEIRCE contribuiu muito provavelmente para sua demissão como professor das Universidades de Harvard e de John Hopkins; para dificultar a publicação de seus escritos e para seu total isolamento nos últimos anos de vida.

The Evolution of Happiness

This literature review analyzes David Buss' evolutionary theory of emotions, which addresses some possible hindrances to positive emotions in today's society. The social function of emotions, sustained happiness, and competition will be looked at in comparison to Buss' article. Buss' theory will then be analyzed to the extent it applies to the human condition today. This review is not exhaustive but merely a brief analysis.

Intangible resources and organization capital: measurement and economic evaluation

Intangible resources have raised the interests of scholars from different research areas due to their importance as crucial factors for firm performance; yet, contributions to this field still lack a theoretical framework. This research analyses the state-of-the-art results reached in the literature concerning intangibles, their main features and evaluation problems and models. In search for a possible theoretical framework, the research draws a kind of indirect analysis of intangibles through the theories of the firm, their critic and developments. The heterodox approaches of the evolutionary theory and resource-based view are indicated as possible frameworks. Based on this theoretical analysis, organization capital (OC) is identified, for its features, as the most important intangible for firm performance. Empirical studies on the relationship intangibles-firm performance have been sporadic and have failed to reach firm conclusions with respect to OC; in the attempt to fill this gap, the effect of OC is tested on a large sample of European firms using the Compustat Global database. OC is proxied by capitalizing an income statement item (Selling, General and Administrative expenses) that includes expenses linked to information technology, business process design, reputation enhancement and employee training. This measure of OC is employed in a cross-sectional estimation of a firm level production function - modeled with different functional specifications (Cobb-Douglas and Translog) - that measures OC contribution to firm output and profitability. Results are robust and confirm the importance of OC for firm performance.
