    Until today, there is no research dedicated to studying the Fatimid-Andalusi relationship. Most of the studies that deal with the subject, either they were in the scope of archaeology, archaeometry, art history or history, are specific and limited to one material or a particular site. This dissertation presents a comprehensive study of all the Fatimid materials found in the Iberian Peninsula and their influences during the Xth-XIIth centuries. It collects all the results from the different academic references to build a database to be analysed according to the geographical distribution, the chronology and the amounts. Furthermore, the analysis results are compared with the historical facts to see their rapprochement to the Fatimid-Andalusi relationships

    Stress induced polarization of immune-neuroendocrine phenotypes in Gallus gallus

    Immune-neuroendocrine phenotypes (INPs) stand for population subgroups differing in immune-neuroendocrine interactions. While mammalian INPs have been characterized thoroughly in rats and humans, avian INPs were only recently described in Coturnix coturnix (quail). To assess the scope of this biological phenomenon, herein we characterized INPs in Gallus gallus (a domestic hen strain submitted to a very long history of strong selective breeding pressure) and evaluated whether a social chronic stress challenge modulates the individuals’ interplay affecting the INP subsets and distribution. Evaluating plasmatic basal corticosterone, interferon-γ and interleukin-4 concentrations, innate/acquired leukocyte ratio, PHA-P skin-swelling and induced antibody responses, two opposite INP profiles were found: LEWIS-like (15% of the population) and FISCHER-like (16%) hens. After chronic stress, an increment of about 12% in each polarized INP frequency was found at expenses of a reduction in the number of birds with intermediate responses. Results show that polarized INPs are also a phenomenon occurring in hens. The observed inter-individual variation suggest that, even after a considerable selection process, the population is still well prepared to deal with a variety of immune-neuroendocrine challenges. Stress promoted disruptive effects, leading to a more balanced INPs distribution, which represents a new substrate for challenging situations.Fil: Nazar, Franco Nicolas.

    Thalassologies of Empire and Republic: Competing for knowledge of the South Eastern Pacific in the Age of Revolutions

    Get PDF
    The waters to the south and east of South America came to play increasingly important commercial, geographical, and political roles from the mid-eighteenth century onwards as they crucially connected the Atlantic to the Pacific Oceans. It was British sailor George Anson’s expedition (1740-44) that opened up this little-known waterscape, dominated by Spanish maritime power since the sixteenth century, to an intense competition for knowledge between the European empires. Moreover, by the late 1700s, the active presence of whalers had transformed this environment into a space of economic exploitation, generating new empirical knowledge about its geography and resources. This thesis explores the varying ways in which this maritime space, to be analysed as the South Eastern Pacific (SEP), became integrated into British, Spanish, and Spanish American systems of knowledge from the 1740s to the 1840s. By examining a wide range of primary sources, from manuscript documents including geographical reports and maps, to published texts such as newspapers, periodicals and scientific journals, it argues that the production of knowledge about the SEP became strategic for imperial and nation-building processes during the Age of Revolutions. This thesis’s chapters address how imperial rivalries shaped knowledge production and how the commodification of the oceans impacted the transfer of knowledge, assessing the changes and continuities brought about by the dissolution of the Spanish Empire and the emergence of Chile as a nation-state. It also examines the ways in which knowledge was socially validated, elaborating upon the construction of knowledge as a collective enterprise and emphasising the variety of actors involved, studying traditional figures such as explorers and naturalists, and less-studied actors such as engineers, indigenous sailors, and whalers. By doing so, this thesis contributes new ways of understanding imperial rivalries, the national project of Chile as an emergent republic, and the history of knowledge in Latin America

    Analysis of the presence of sustainability in Higher Education Degrees of the Spanish university system

    Get PDF
    This paper analyzes the extent to which sustainability is present in the curricula of the 16 Education Degree programs belonging to the EDINSOST project: 6 Early Childhood Education Degrees, 7 Primary Education Degrees, 2 Pedagogy Degrees and 1 Social Education Degree. The results obtained suggest that sustainability is present in all Degrees, but not uniformly so. A great disparity is observed in the number of subjects that develop sustainability, with an average of 22.63 subjects per Degree. The competency most present is the ‘ Application of ethical principles related to the values of sustainability in personal and professional behaviors, ’ while the least present is ‘ Sustainable use of resources and prevention of negative impacts on the natural and social environment. ’Sustainability is not developed uniformly in the different universities either. Three universities (UAM, UCA and UIC) develop sustainability competencies at 100%, while others such as the USAL do so at only 50

    Analysis of ecosystem services provision in the Colombian Amazon using participatory research and mapping techniques

    Get PDF
    Over the last two decades indigenous peoples in the lower Caquetá River basin in Colombia have experienced detrimental changes in the provision of important ecosystem services in ways that have significant implications for the maintenance of their traditional livelihoods. To assess these changes we conducted eight participatory mapping activities and convened 22 focus group discussions. We focused the analysis on two types of change: (1) changes in the location of ecosystem services provisioning areas and (2) changes in the stock of ecosystem services. The focal ecosystem services include services such as provision of food, raw materials and medicinal resources. Results from the study show that in the past two decades the demand for food and raw materials has intensified and, as a result, locations of provisioning areas and the stocks of ecosystem services have changed. We found anecdotal evidence that these changes correlate well with socio-economic factors such as greater need for income generation, change in livelihood practices and consumption patterns. We discuss the use of participatory mapping techniques in the context of marginalized and data-poor regions. We also show how this kind of information can strengthen existing ecosystem-based management strategies used by indigenous peoples in the Colombian Amazon

    "Moral Revenge of the Crowd” in the 1854 Revolution in Madrid

    Get PDF
    The 1854 revolution in Spain has been relatively little studied. Here we try to understand and explain the phenomenon from a Cultural History perspective. In 1854 Spain suffered several Progresist-cut revolutions which took place caused by an unsustainable situation: the Conservative groups (called moderates) had held power for ten years, with politics of its last years being a nest of corruption, ornamented with anti-constitutional nuances. The situation was worsened by a famine, which stimulated a military led revolution, followed by a popular uprising. This was successful in Madrid, and promptly extended from here to various Spanish provinces. This article analyses the attacks that took place against the Conservative power groups. Studies the war in the streets, looking for popular justice in a sort of moral revenge of the multitude (paraphrasing Edward P. Thompson’s expression), by selectively targeting the symbols of power. It takes into account the collective mentalities, the constructive processes leading to the representations of power, the systems leading to the resistance against it and the mobilisation of the masses, with the specific manner of assimilation Liberalism undertook to put popular justice in place. The result was the triumph of Liberalism, which would sustain power between 1854 and 1856 (progressive biennium), popular victory that transformed the way the power looked back to that revolution

    Preliminary Study of Recycled Aggregate Mortar for Electric Arc Furnace Dust Encapsulation

    Get PDF
    This article shows the preliminary results of a study carried out to determine the technical feasibility of encapsulating a high percentage of EAFD in cement-based mortars manufactured with the fine fraction of recycled concrete aggregates (RCA). Two families of mortars, with natural aggregate as a reference and with RCA, were studied. An incorporation rate by weight of two parts mortar to one part EAFD was tested. The mechanical strengths (compressive strength and tensile strength) before and after immersion in water, the rate of delitescence and the leaching behavior were studied. Mortars made with RCA showed similar mechanical strengths to the reference mortars made with natural aggregates; however, the incorporation of EAFD decreased the mechanical strengths. Encapsulation considerably reduced the leaching of heavy metals, although the Pb concentration remained above the hazardous waste limit. With this preliminary study, two wastes are managed together, and the results have shown that the use of RCA instead of natural aggregate is a viable alternative since it does not significantly impair the mechanical or leaching properties of the cement-based matrices used to encapsulate EAFD

    Bibliography of Structuralism III

    Get PDF
    In two occasions a Bibliography of Structuralism has been published in Erkenntnis (1989, 1994). Since then a lot of water has flowed under the bridge and the structuralist program has shown a continuous development. The aim of the present bibliography is to celebrate the 25th anniversary of the publication of An Architectonic for Science –structuralism’s main reference work– and of its recent translation into Spanish by updating the previous bibliographies with titles which have appeared since 1994 as well as before that year but which are not included in them. As in the former deliveries, this bibliography only covers books and articles that are concerned directly with the structuralist approach in the philosophy of science. We would like to thank the many colleagues who have helped us in collecting all the information. Notwithstanding we apologize in advance for the possible entries that we missed to include in this third Bibliography of Structuralism

    Challenges and responses of agri-food activities under COVID-19 pandemic: The case of the Spanish territories producing wine and olive oil

    Get PDF
    Producción CientíficaThe COVID-19 pandemic has deeply affected economic activities worldwide. The challenge for territories and companies has been how to cope with mobility restrictions. Even in the case of essential activities such as agri-food industries, the adaptation has been a challenging issue to deal with. The paper aims to show how the wine and olive oil industries in Spain have restructured their activities in order to respond to the confinement and the new normalcy, using new technologies as a strategic tool, but also making the most of new actions to keep their presence in the national and international markets. The research was carried out mostly through qualitative analysis, using the in-depth interview as a main tool to gain strategic information from managers of companies and local policymakers. Results show that when local policy makers and managers cooperate, despite the different perceptions they could have, the outcome is positive for facing competitive shocks and carving out new local initiatives, making firms and the territory itself more resilient

    El mundo hispánico en guerra y la transformación del comercio mundial. Comerciantes globales en la América española: redes, negocios e Independencia (1800-1830)

    Get PDF
    Aquest número monogràfic investiga com els comerciants van contribuir a la construcció d’un nou ordre en temps de guerra, conflicte polític i disrupció de les pràctiques comercials durant l’Era de les Revolucions, dos segles enrere. Aquest aplec d’articles forma part d’una lectura policèntrica de transformacions històriques que –sense negar la primacia de la política i del poder militar– subratlla les negociacions complexes que hi va haver a la base de l’establiment de noves relacions de força. Analitza així les profundes conseqüències globals de la caiguda de l’Imperi Espanyol a Amèrica, particularment pel que fa al declivi del mercantilisme i a la reconfiguració del comerç atlàntic i inter-pacífic. Un element crucial d’aquesta transformació en va ser l’economia de guerra, que va tenir implicacions no tan sols a l’Amèrica espanyola, sinó també en el conjunt del món hispànic i més enllà. Homes de negocis i comerciants globals, tant estrangers com hispànics, estratègicament situats en un espai imperial en fragmentació, les xarxes i negocis dels quals unien Europa, Àsia i les Amèriques, van actuar en el buit creat per la crisi de la monarquia espanyola, en el que va ser un moment fluid i fundacional. Mitjançant l’anàlisi de les xarxes de negocis i personals que van construir, redefinir i renegociar el rol de l’Amèrica hispànica en l’economia global, els treballs d’aquest número investiguen com les Guerres napoleòniques i les Guerres d’Independència contra Espanya van accelerar l’emergència de nous actors, pràctiques, regles del joc i circuits mercantils. Aquesta prosopografia de comerciants trans-regionals i globals, per tant, mostra trajectòries a través de les quals, malgrat la dificultat, aquests comerciants apareixen com una força maièutica en el naixement del món modern.This special issue investigates how in the times of war, political turmoil, and disruption of commercial practices during the Age of Revolutions two centuries ago, merchants appear as demiurges of a new order. This is part of a polycentric reading of epochal transformations that does not deny the primacy of politics and military power in establishing relations of force, but which underlines the complex negotiations at their base. The collection of essays looks at the profound global consequences of the fall of the Spanish American empire, particularly as they related to the decline of mercantilism and the reconfiguration of both Atlantic and inter-Pacific commerce. A crucial element in this transformation was the war economy, which had implications not only in Spanish America, but in the whole of the Hispanic world and beyond. Global merchants or businessmen —foreigners and Hispanic— strategically located in the Hispanic World, whose networks and affairs linked Europe, Asia and the Americas, worked within the vacuum created by the crisis of the Spanish monarchy in what was a fluid and foundational moment. The essays investigate how the Napoleonic Wars and the Wars of Independence against Spain accelerated the emergence of new actors, practices, rules and commercial circuits, by analyzing the personal and business networks that built, redefined and renegotiated the role of Hispanic America in the global economy. This prosopography of merchants thus shows trajectories through which, despite infinite difficulties, global and transregional merchants appear as one of the maieutic forces in the birth of the modern world.Este número monográfico investiga cómo los comerciantes contribuyeron a la construcción de un nuevo orden en tiempos de guerra, conflicto político y disrupción de las prácticas comerciales durante la Era de las Revoluciones, dos siglos atrás. Este conjunto de artículos forma parte de una lectura policéntrica de transformaciones históricas que –sin negar la primacía de la política y del poder militar– subraya las negociaciones complejas que estuvieron en la base del establecimiento de nuevas relaciones de fuerza. Analiza así las profundas consecuencias globales de la caída del Imperio Español en América, particularmente en lo que se refiere al declive del mercantilismo y a la reconfiguración del comercio atlántico e inter-pacífico. Un elemento crucial de esta transformación fue la economía de guerra, que tuvo implicaciones no tan solo en la América española, sino en el conjunto del mundo hispánico y más allá. Hombres de negocios y comerciantes globales, tanto extranjeros como hispánicos, estratégicamente situados en un espacio imperial en fragmentación, y cuyas redes y negocios unían Europa, Asia y las Américas, actuaron en el vacío creado por la crisis de la monarquía española, en lo que fue un momento fluido y fundacional. Mediante el análisis de las redes de negocios y personales que construyeron, redefinieron y renegociaron el rol de la América hispánica en la economía global, los trabajos en este número investigan cómo las Guerras napoleónicas y las Guerras de Independencia contra España aceleraron la emergencia de nuevos actores, prácticas, reglas del juego y circuitos mercantiles. Esta prosopografía de comerciantes trans-regionales y globales, por consiguiente, muestra trayectorias a través de las cuales, a pesar de la dificultad, dichos comerciantes aparecen como una fuerza mayéutica en el nacimiento del mundo moderno
