Incidencia del frente Polisario en la búsqueda del reconocimiento internacional del Sahara Occidental

Esta monografía revisa algunos de los sucesos más significativos que han incidido en el movimiento de reivindicación del Frente Polisario, en la búsqueda del reconocimiento internacional del Sahara Occidental. Para ello, la investigación se ocupa de describir y analizar los hechos que han permitido la evolución de la estructura de oportunidades política, en medio la cual se ha llevado el accionar del Frente Polisario, a través de los diferentes repertorios de acción colectiva que han facilitado la internacionalización de la causa saharaui. Para tal fin, se usan los postulados teórico-conceptuales tomados de los estudios sobre movimientos sociales. La investigación concluye con una serie de reflexiones que permiten tener un mayor acercamiento a la situación del Sahara Occidental y a los factores que han permitido generar mayor solidaridad en torno a la lucha saharaui.

Casa Dental Eduardo Daza Ltda. Un estudio de caso de perdurabilidad empresarial

Este trabajo presenta un estudio de caso de perdurabilidad empresarial de la empresa Casa Dental Eduardo Daza Ltda, que como Empresa de Familia, desafía la tendencia de su desaparición a partir de la tercera generación, como lo han hecho la mayoría de empresas de esta naturaleza a nivel mundial. En primera instancia se contextualiza y caracteriza las empresas de familia a nivel mundial a partir de una revisión de la literatura existente, para poder consolidar un marco referencial que permite una aproximación al estado del arte en el ámbito corporativo de empresas de naturaleza familiar, para luego analizar su dinámica actual en la economía colombiana, en un enfoque desde lo general a lo particular. Posteriormente se presenta las características que demarcan el éxito de las empresas de familia, su gestión y gobernabilidad, el protocolo de traspaso y el direccionamiento estratégico hacia la innovación como sinónimo que garantiza la perdurabilidad en el tiempo. Después de esta contextualización, se presenta las particularidades desde un contexto histórico de la empresa Casa Dental Eduardo Daza Ltda, sus vicisitudes corporativas, su decadencia y renacer, hasta convertirse en un caso de éxito empresarial a nivel de empresa de familia, sustentando en su comportamiento económico financiero en los últimos tres años, para poder definir sus particularidades, tendencias y prospectiva en el inmediato futuro. Se concluye que las empresas de familia como forma más antigua de organización empresarial, tienen un amplio reconocimiento como un actor importante y diferenciador de la economía mundial, pues el aparato productivos de muchos países desarrollados y en vías de desarrollo se soporta en empresas de familia. La evidencia empírica señala dos características distintivas de las empresas de familia: 1) en casi todos los países estas empresas tienen una alta participación en la creación de riqueza; y 2) tienen una alta probabilidad de desaparecer. En todas las economías, en mayor o menor grado, conviven estos dos fenómenos tan significativos: su importancia económica y su vulnerabilidad

Capturing and sharing our collective expertise on climate data: the CHARMe project

For users of climate services, the ability to quickly determine the datasets that best fit one's needs would be invaluable. The volume, variety and complexity of climate data makes this judgment difficult. The ambition of CHARMe ("Characterization of metadata to enable high-quality climate services") is to give a wider interdisciplinary community access to a range of supporting information, such as journal articles, technical reports or feedback on previous applications of the data. The capture and discovery of this "commentary" information, often created by data users rather than data providers, and currently not linked to the data themselves, has not been significantly addressed previously. CHARMe applies the principles of Linked Data and open web standards to associate, record, search and publish user-derived annotations in a way that can be read both by users and automated systems. Tools have been developed within the CHARMe project that enable annotation capability for data delivery systems already in wide use for discovering climate data. In addition, the project has developed advanced tools for exploring data and commentary in innovative ways, including an interactive data explorer and comparator ("CHARMe Maps") and a tool for correlating climate time series with external "significant events" (e.g. instrument failures or large volcanic eruptions) that affect the data quality. Although the project focuses on climate science, the concepts are general and could be applied to other fields. All CHARMe system software is open-source, released under a liberal licence, permitting future projects to re-use the source code as they wish.

Science Teacher Education in Brazil: 1950-2000

This paper analyzes the most significant events occurring in Brazil`s educational, social and political areas over the last half century, viewed against a background of relevant worldwide events. The hypothesis presented here is that the relations between the country`s educational policies, the demands of the various segments of academia, and the public school system have always been strained. This strain has contributed positively to the evolution of academic knowledge and production, to the design of more modern curricular projects by institutional authorities, and to the initial recognition of the specific construction of school knowledge by the school system itself. However, the interaction of these major institutions lacks a crucial element-one that would lead to an effective change in the education of science teachers and produce a positive impact on Brazil`s schools-namely, the wholehearted participation of science teachers themselves. With this analysis, we intend to contribute by offering some perspectives and proposals for science teacher education in Brazil.

Report on Recent Large Bird Ingestions into Transport Turbofan Engines

Today I am going to give you a report on recent bird ingestion events into transport category turbofan engine in commercial service. We are still having these events. We may not ever completely eliminate all such events, but our purpose for meeting is to put all our resources to work to try. The events that I am going to report on today represent some of the more significant events over the last couple of years. The events are significant because of the potential for jeopardizing the safety of the aircraft involved and the aircraft occupants. The events I am going to discuss all involve encounters with large birds. Each situation reflects a bird control issue or event that resulted in a high workload for the flight crew because something out of the ordinary happened that they had to respond to. Some of the situations involve areas outside the US or Canada but serve as a lesson because that the same situation can happen here.

Mutual Information Rate and Bounds for It

The amount of information exchanged per unit of time between two nodes in a dynamical network or between two data sets is a powerful concept for analysing complex systems. This quantity, known as the mutual information rate (MIR), is calculated from the mutual information, which is rigorously defined only for random systems. Moreover, the definition of mutual information is based on probabilities of significant events. This work offers a simple alternative way to calculate the MIR in dynamical (deterministic) networks or between two time series (not fully deterministic), and to calculate its upper and lower bounds without having to calculate probabilities, but rather in terms of well known and well defined quantities in dynamical systems. As possible applications of our bounds, we study the relationship between synchronisation and the exchange of information in a system of two coupled maps and in experimental networks of coupled oscillators.

Trust and Social Networks in a Changing Europe.

This project set out to investigate the effects of the recent massive social transitions in Eastern Europe on the everyday social lives of the inhabitants of three very different nations: Georgia, Russia and Hungary. It focused in particular on the availability and nature of the support networks available to three different segments of each of the societies (manual workers, students and entrepreneurs) and the impact of network participation on psychological and physical well-being. The group set four specific questions to investigate: the part played by individual psychological beliefs in the formation and maintenance of social networks and the consequent formation of trusting relations; the implication of the size and quality of these networks for mental health; the nature of the social groups inhabited by the respondents and the implication of their work schedule and daily routines on the maintenance of a social and family life; and an analysis of how cultures vary in their social networks and intimacy. Three different methods were used to examine social support and its implications: structured questionnaires, semi-structured short interviews and a media analysis of newspaper materials. The questionnaires were administered to 150 participants in each country, equally divided between students studying full time, manual workers employed in factories, and business people (small kiosk owners, whose work and life style differs considerably from that of the manual workers). The questionnaires investigated various predictors of social support including the locus of control, relationship beliefs, individualism-collectivism and egalitarianism, demographic variables (age, gender and occupation), social support, both in general and in relation to significant events that have occurred since the transition from communism. Those with an internal locus of control were more likely to report a higher level of social support, as were collectivists, while age too was a significant predictor, with younger respondents enjoying higher levels of support, regardless of the measures of support employed. Respondents across the cultures referred to a decline of social support and the group also found a direct correlation between social support and mental health outcomes. All 450 respondents were interviewed on their general responses to changes in their lives since the fall of communism and the effects of their work lives on their social lives and the home environment. The interviews revealed considerable variations in the way in which work-life offered opportunities for a broader social life and also provided a hindrance to the development of fulfilling relationships. Many of the work experiences discussed were culture specific, with work having a particularly negative impact on the social life of Russian entrepreneurs but being seen much more positively in Georgia. This may reflect the nature of support offered in a society as overall support levels were lowest in Russia, meaning that social support may be of particular importance there. The way in cultural values and norms about personal relationships are transmitted in a culture is a critical issue for social psychologists and the group examined newspaper articles in those newspapers read by the respondents in each of the three countries. These revealed a number of different themes. The concept of a divided society and its implications for personal relationships was clearest in Russian and Hungary, where widely-read newspapers dwelt on the contrast between "new Russians/Hungarians" and the older, poorer ones and extended considerable sympathy to those suffering from neglect in institutions. Magyar Nemzet, a paper widely read by Hungarian students reflects the generally more pessimistic tone about personal relationships in Russia and Hungary and gave a particularly detailed analysis of the implications this holds for human relations in a modern society. In Georgia, however, the tone of the newspapers is more positive, stressing greater social cohesion. Part of this cohesion is framed in the context of religion, with the church appealing to a broader egalitarianism, whereas in less egalitarian Hungary appeals by the Church are centred more on the nuclear family and its need for expansion in both size and influence. The division between the sexes was another prominent issue in Hungary and Russia, while the theme of generational conflict also emerged in Hungarian and Georgian papers, although with some understanding of "young people today". The team's original expectation that the different newspapers read by the different groups of respondents would present differing images of personal relationships was not fulfilled, as despite variations in style, they found little clear "ideological targeting" of any particular readership. They conclude that the vast majority of respondents recognised that the social transition from communism has had a significant impact on the well-being of social relationships and that this is a pertinent issue for all segments of society. While the group see the data collected as a source to be worked on for some time in the future, their initial impressions include the following. Social support is clearly an important concern across all three countries. All respondents (including the students) lament the time taken up by their heavy work schedules and value their social networks and family ties in particular. The level of social support differs across the countries investigated, with Georgian apparently enjoying significantly higher levels of social support. The analysis produced an image of a relatively cohesive and egalitarian society in which even the group most often seen as distant from the general population, business people, is supported by a strong social network. In contrast, the support networks available to the Russian respondents seem particularly weak and reflect a general sense of division and alienation within the culture as a whole. The implications of low levels of social support may vary across countries. While Russians reported the lowest level of mental health problems, the link between social support and mental health may be strongest in that country. In contrast, in Hungary it is the link between fatalism and mental health problems which is particularly strong, while in Georgia the strongest correlation was between mental health and marital quality, emphasising the significance of the marital relationship in that country.

A Comparative Chronology of the History of Eastern Europe and the Climate

Two main areas were examined in this project: * The detailed climatic history of the second part of the Holocene (approximately the last 5500 calendar years) for the Zapadnodvinskaya lowland, making it possible to reconstruct general climatic changes in eastern Europe (taking other palynological, dendrochronological, historical and instrumental data into account). * The most important historical events for the period of the 9th-17th centuries that had an impact on Russian history. The comparative chronology of the main climatic changes and events of Russian social history showed that as local climatic conditions became worse (i.e. falling average annual temperature or precipitation rate) the density of significant events in society rose. This suggests that climatic deterioration is both a stimulus and an outstanding factor in social development.

Finnish Fighting Words: Printing the Työmies Translation Project

The Työmies translation project involves the translation of that newspaper’s accounts of significant events from Michigan’s 1913-1914 Copper Strike. Työmies was a Finnish-language newspaper, published in Hancock, Michigan, whose socialist-unionist perspective on the strike differed markedly from that of the local English-language newspapers. This project is the first time significant portions of Työmies have been translated into English. In June of 2013, the presenter printed the translation of the Työmies account of the strike’s first day on a hand-operated Chandler & Price platen press. Thus, the presentation describes this unique project: the translation itself, the presenter’s search for necessary type and equipment, and the printing of the broadsides. The presentation will include a history of Työmies and the Strike, with an emphasis on ways in which human culture and language is reflected in the material culture of printing.

Navegar en la tormenta : El anticomunismo en la historiografía de los Estados Unidos durante la Guerra Fría

Este artículo indaga la gravitación del anticomunismo en la historiografía norteamericana durante la guerra fría. Comienza con una reconstrucción histórica de tal actitud política en la sociedad americana; luego analiza la expansión, características y perdurabilidad del macartismo y, finalmente, describe sus consecuencias sobre la investigación, enseñanza y divulgación de la historia. Analiza como fuentes principales a las obras historiográficas y a los historiadores que sufrieron las ráfagas del anticomunismo; así como a las resoluciones e interpretaciones que desde el propio campo de la disciplina y de las agencias gubernamentales legitimaron la necesidad de prohibir y expurgar la influencia marxista sobre el campo de la cultura, de la educación y del saber histórico. El artículo explica la manera en que las prácticas persecutorias afectaron la carrera de historiadores izquierdistas o progresistas y cómo impactaron sobre las interpretaciones de procesos y acontecimientos significativos del pasado de la gran nación americana.
