Exilio, migración, destierro? : Los trabajadores chilenos que se asentaron en el Nor Este de Chubut a partir de Septiembre de 1973. Memorias, historias e implicancias

En este trabajo abordamos el análisis de experiencias exiliares de trabajadores chilenos que se radicaron en el Noreste de la Provincia de Chubut, en Patagonia Argentina, después de producido el golpe de estado contra el presidente democrático Salvador Allende Gossens, en Septiembre de 1973. Cuando revisé la factibilidad de la investigación, y en mérito a los escasos repositorios documentales, decidí, dando continuidad a indagaciones previas, trabajar con historia oral. Esta metodología o práctica, involucra una dimensión personal, subjetiva y afectiva, que supone una constante relación entre los sujetos que participan, lo que implica una cualitativa diferencia en relación a las fuentes más tradicionales. No minimizo el valor de la estadística, pero hago una opción por nombrar y conocer a quienes han compartido con nosotros vivencias y experiencias, explicitando nuestra inscripción en la construcción de la información documental, no objetivándonos. El trabajo desarrollado se halla en la encrucijada entre la historia del pasado reciente y la memoria; con una perspectiva "desde abajo", buscando conjugar la no uniformidad de la experiencia humana, con la pretensión de generalidad y explicación de la ciencia social. Las narraciones o testimonios obtenidos las he revisado, procurando develar las representaciones que subyacen, y comprendiendo el modo en que actuaron. Las memorias tienen un carácter subjetivo y en permanente transformación, lo que en cierto sentido puede singularizarlas, pero como historiadores debemos inscribirlas en un contexto histórico global, para procurar esclarecer las causas, las condiciones, y las estructuras, aportando a una historia total. Hemos rescatado prácticas, percepciones, y discursos; develando la importancia del trabajo como factor organizador y estabilizador, al dotar a estos sujetos, de un sitio en la sociedad receptora, y permitiéndoles "ir desarmando sus valijas", es decir, ir superando la transitoriedad. Al caracterizar al exilio chileno, en el contexto internacional y local; y atendiendo a las escasas producciones que dan cuenta del universo obrero en estas experiencias traumáticas, han sido evidentes los límites que supone una estricta separación entre exilio, y migración económica o política; ya que dicha conceptualización encierra una mirada que invisibiliza derroteros que en principio, o superficialmente, pueden ser leídos como poco organizados. La aplicación del análisis de red, por cierto contribuyó a hacerlos visibles, transformándolos en actores racionales, con objetivos que se movilizaron a partir de los recursos de que dispusieron; tratando de superar el paradigma que hacía de ellos seres desesperados: fueron mujeres y hombres que eligieron un destino posible, siempre atendiendo al doble carácter de la experiencia en que estuvieron inmersos: la salida de su país por un lado los liberó, pero también los privó; asociando indisolublemente sentimientos de dolor por el desprendimiento de lo propio -de los afectos personales y colectivos-, agravados por los efectos de la derrota y la incertidumbre. Son sujetos que pusieron su identidad en riesgo. Pretendemos lograr que esta investigación, no sea sólo un estudio de caso, sino que pueda inscribirse a partir de su especificidad, en tanto exilio obrero, en una perspectiva comparativa, superando una definición espacial específica, en el Nor Este de Chubut.

Analysis and visualization of the dynamics of research groups in terms of projects and co-authored publications : A case study of library and information science in Argentina

Objective: The present study offers a novel methodological contribution to the study of the configuration and dynamics of research groups, through a comparative perspective of the projects funded (inputs) and publication co-authorships (output). Method: A combination of bibliometric techniques and social network analysis was applied to a case study: the Departmento de Bibliotecología (DHUBI), Universidad Nacional de La Plata, Argentina, for the period 2000-2009. The results were interpreted statistically and staff members of the department, were interviewed. Results: The method makes it possible to distinguish groups, identify their members and reflect group make-up through an analytical strategy that involves the categorization of actors and the interdisciplinary and national or international projection of the networks that they configure. The integration of these two aspects (input and output) at different points in time over the analyzed period leads to inferences about group profiles and the roles of actors. Conclusions: The methodology presented is conducive to micro-level interpretations in a given area of study, regarding individual researchers or research groups. Because the comparative input-output analysis broadens the base of information and makes it possible to follow up, over time, individual and group trends, it may prove very useful for the management, promotion and evaluation of science

The determinants of the quality of Sales-Marketing Interface in a Multinational Customer Brand Focused Company: The Latin American Branches

Customer evolution and changes in consumers, determine the fact that the quality of the interface between marketing and sales may represent a true competitive advantage for the firm. Building on multidimensional theoretical and empirical models developed in Europe and on social network analysis, the organizational interface between the marketing and sales departments of a multinational high-growth company with operations in Argentina, Uruguay and Paraguay is studied. Both, attitudinal and social network measures of information exchange are used to make operational the nature and quality of the interface and its impact on performance. Results show the existence of a positive relationship of formalization, joint planning, teamwork, trust and information transfer on interface quality, as well as a positive relationship between interface quality and business performance. We conclude that efficient design and organizational management of the exchange network are essential for the successful performance of consumer goods companies that seek to develop distinctive capabilities to adapt to markets that experience vertiginous changes

Evolution of the Riparian forest corridor in a large Mediterranean river system

The well-documented re-colonisation of the French large river basins of Loire and Rhone by European otter and beaver allowed the analysis of explanatory factors and threats to species movement in the river corridor. To what extent anthropogenic disturbance of the riparian zone influences the corridor functioning is a central question in the understanding of ecological networks and the definition of restoration goals for river networks. The generalist or specialist nature of target species might be determining for the responses to habitat quality and barriers in the riparian corridor. Detailed datasets of land use, human stressors and hydro-morphological characteristics of river segments for the entire river basins allowed identifying the habitat requirements of the two species for the riparian zone. The identified critical factors were entered in a network analysis based on the ecological niche factor approach. Significant responses to riparian corridor quality for forest cover, alterations of channel straightening and urbanisation and infrastructure in the riparian zone are observed for both species, so they may well serve as indicators for corridor functioning. The hypothesis for generalists being less sensitive to human disturbance was withdrawn, since the otter as generalist species responded strongest to hydro-morphological alterations and human presence in general. The beaver responded the strongest to the physical environment as expected for this specialist species. The difference in responses for generalist and specialist species is clearly present and the two species have a strong complementary indicator value. The interpretation of the network analysis outcomes stresses the need for an estimation of ecological requirements of more species in the evaluation of riparian corridor functioning and in conservation planning.

Feature selection in the reconstruction of complex network representations of spectral data

Complex networks have been extensively used in the last decade to characterize and analyze complex systems, and they have been recently proposed as a novel instrument for the analysis of spectra extracted from biological samples. Yet, the high number of measurements composing spectra, and the consequent high computational cost, make a direct network analysis unfeasible. We here present a comparative analysis of three customary feature selection algorithms, including the binning of spectral data and the use of information theory metrics. Such algorithms are compared by assessing the score obtained in a classification task, where healthy subjects and people suffering from different types of cancers should be discriminated. Results indicate that a feature selection strategy based on Mutual Information outperforms the more classical data binning, while allowing a reduction of the dimensionality of the data set in two orders of magnitude

Analysis of the essential literature on project management in Spanish

The advancement of science and engineering projects is brewing major changes in the various phases of a project. These changes have produced more rigorous aspects of project management that tracks the research fronts of engineering and project management becomes key. However, research in engineering and project management in Spanish is hindered by access to information to enable the person concerned to ascertain the most recent and current research, limiting the exchange of information and strengthening research networks in this field interest with great implications in business, industry and scientific issues. Therefore, the article aims to present the state of the art of engineering research and project management in Spanish, using the analysis of scientific domains and network analysis of the research literature to identify and analyze relationships between authors and documents that establish the base and research fronts topic under study. The results also provide statistics on the contribution of international research in Spanish and scientific collaboration networks.

The structure and infrastructure of Mexico's science and technology

The structure and infrastructure of the Mexican technical literature was determined. A representative database of technical articles was extracted from the Science Citation Index for the year 2002, with each article containing at least one author with a Mexican address. Many different manual and statistical clustering methods were used to identify the structure of the technical literature (especially the science and technology core competencies). One of the pervasive technical topics identified from the clustering, thin films research, was analyzed further using bibliometrics, in order to identify the infrastructure of this technology.

Transcriptional network dynamics in macrophage activation

Transcriptional regulatory networks govern cell differentiation and the cellular response to external stimuli. However, mammalian model systems have not yet been accessible for network analysis. Here, we present a genome-wide network analysis of the transcriptional regulation underlying the mouse macrophage response to bacterial lipopolysaccharide (LPS). Key to uncovering the network structure is our combination of time-series cap analysis of gene expression with in silico prediction of transcription factor binding sites. By integrating microarray and qPCR time-series expression data with a promoter analysis, we find dynamic subnetworks that describe how signaling pathways change dynamically during the progress of the macrophage LPS response, thus defining regulatory modules characteristic of the inflammatory response. In particular, our integrative analysis enabled us to suggest novel roles for the transcription factors ATF-3 and NRF-2 during the inflammatory response. We believe that our system approach presented here is applicable to understanding cellular differentiation in higher eukaryotes. (c) 2006 Elsevier Inc. All rights reserved.

Globalisation and connectedness: A network approach to international business

There have been recent calls for the field of International Business to retool its routines by becoming genuinely interdisciplinary. This paper takes such an approach by using recent advances in the fields of evolutionary economics and applying them to IB. Evolutionary economists are now viewing the economy as an actual network. Consequently, one the key analytical tools in this approach is network analysis. Some of the basic methods in network analysis are reviewed. The paper then looks at how using these tools might be of use in IB studies. In particular, it outlines fruitful research paths in the areas of globalisation and regionalisation, and the measurement of performance in multi-national firms and alliances. In each case, propositions are put forward which can be analytically tested with the use of network analysis. The paper concludes with a brief outline of a research agenda which utilises this approach in International Business studies.

A real options based method for power system planning

A deregulated electricity market is characterized with uncertainties, with both long and short terms. As one of the major long term planning issues, the transmission expansion planning (TEP) is aiming at implementing reliable and secure network support to the market participants. The TEP covers two major issues: technical assessment and financial evaluations. Traditionally, the net present value (NPV) method is the most accepted for financial evaluations, it is simple to conduct and easy to understand. Nevertheless, TEP in a deregulated market needs a more dynamic approach to incorporate a project's management flexibility, or the managerial ability to adapt in response to unpredictable market developments. The real options approach (ROA) is introduced here, which has clear advantage on counting the future course of actions that investors may take, with understandable results in monetary terms. In the case study, a Nordic test system has been testified and several scenarios are given for network expansion planning. Both the technical assessment and financial evaluation have been conducted in the case study.
