El armamento de influencia La Tène en la Península Ibérica (siglos V-I a.C.)

El armamento de tipo La Tène se ha venido relacionando habitualmente con la Segunda Edad del Hierro europea, y en general con un territorio dominado por poblaciones de etnia celta. Sin embargo, en la actualidad su alcance llega a un territorio más amplio, que en particular afecta a buena parte de la Europa occidental. En este trabajo se analizan y estudian las armas de influencia La Tène en la Península Ibérica a partir de la información directa del material arqueológico. Además de un catálogo exhaustivo de estas armas para el territorio, se realizan una serie de propuestas tipológicas y se procede al estudio de los conjuntos de armas (panoplias) y a procurar resolver las cuestiones de la llegada de estos influjos, de las vías de propagación de las armas, de sus características y peculiaridades morfológicas y tecnológicas y, finalmente, de su evolución a lo largo de más de cuatro siglos de historia.

Identitat, racisme i violència. Les relacions interètniques en un institut català

Aquesta tesi està basada en l'etnografia d'un institut d'educació secundària situat en una ciutat mitjana de Catalunya, amb un nivell socioeconòmic mig-baix i una important presència d'immigrants (de diferents zones de l'estat espanyol i d'Àfrica, sobretot marroquins i gambians). El treball inclou una recerca bibliogràfica i de clarificació teòrica amb la que es pretén situar els fenòmens que s'estudien (identitat, racisme i violència) en el moment històric i context social actual, per tal de poder explicar l'ascens o la importància d'aquests fenòmens, així com les relacions que es poden establir entre ells. La primera part de la tesi respon a la voluntat de contextualitzar teòricament la recerca etnogràfica i de situar les observacions d'aula en un marc social més ampli. A la segona part es presenten les aportacions que han realitzat els sociòlegs i els antropòlegs de l'educació a l'anàlisi del tractament de la diversitat ètnica, del racisme i de la violència en l'àmbit escolar. A la tercera part es desenvolupa el treball de recerca etnogràfica centrat en l'anàlisi de les relacions interètniques de l'alumnat.

Exclusão étnica, julgamento moral e emoções morais : estudo em adolescentes

Os pressupostos defendidos na declaração de Salamanca sobre a Educação Inclusiva não são fáceis de concretizar pois as pessoas, por causa de diferenças de sexo, etnia, aparência, etc, têm frequentemente condutas diferenciais. Um dos critérios sociais que mais provoca exclusão social são as diferenças étnicas, um fenómeno mais estudado pela psicologia social. Porém, a atitude de exclusão social pode estar relacionada com a competência moral dos indivíduos, uma relação que foi analisada neste estudo. Para isso recorremos ao suporte da psicologia moral que valoriza o papel das emoções na compreensão das condutas sociais, bem exemplificada nos estudos do vitimizador feliz (e.g., Arsenio & Kramer, 1992; Lourenço, 1998). Nas perspectivas mais recentes da psicologia moral tem sido atribuída grande ênfase à necessidade de analisar cognições e emoções nas condutas morais (e.g., Malti & Latzko, 2010; Turiel & Killen, 2010). Apoiados no estudo de Malti, Killen & Gasser (2012) sobre a exclusão social analisámos os julgamentos e as emoções morais de adolescentes em três contextos, etnia africana, etnia cigana e género, numa amostra de 45 adolescentes, com idades entre os 13 e os 19 anos, através da aplicação de uma versão traduzida da Survey Instrument for Measuring Judgments about Emotions about Exclusion (Malti, Killen & Gasser, 2009). Os jovens avaliaram a exclusão étnica como mais incorreta que a exclusão por género mas não foram encontradas diferenças nos juízos e emoções expressas pelos portugueses e estrangeiros. As emoções de culpa, tristeza, vergonha, atribuídas ao excludente confirmam a avaliação negativa da atitude de exclusão. Porém, a emoção normal que revela indiferença expressa que alguns jovens avaliaram positivamente a exclusão. A intensidade emocional intermédia das emoções atribuídas mostra inconsistência com o juízo moral. Relativamente ao excluído existe consenso pois as emoções de tristeza e raiva foram as mais atribuídas. As justificações dos juízos e emoções atribuídos são de tipo diverso, ou seja, argumentos morais de justiça e igualdade, argumentos de inclusão por empatia e argumentos convencionais relativos à coesão intragrupal. A atitude de exclusão não é estritamente moral pois também é vista em função de benefícios para o funcionamento do grupo. A relação complexa entre juízos, emoções e justificações requisita mais investigação de modo a percebermos melhor os processos psicológicos que induzem a conduta social.

Solidaridad étnica y capital social: el caso de los comerciantes migrantes kichwa-Otavalo en Madrid y La Compañía (Estudios)

En el análisis sobre migrantes, en general, y sobre migrantes descritos como grupos étnicos, en concreto, se tiende a presuponer un tipo de “solidaridad étnica” dentro de sus redes sociales. Esta suposición da por sentado que todos los que se definen como “indígenas” disponen y disfrutan de un capital social basado en la solidaridad. En este artículo se toma el caso de comerciantes migrantes kichwa-otavalo tanto para indagar la suposición de que la etnicidad es la fuente del capital social colectivo y, por tanto, de la solidaridad, como para cuestionar si esta actúa implícita en las cadenas y redes de migrantes, las cuales suelen ser equiparadas a su capital social.

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.

Exploring other childhoods through quantitative secondary analyses of large scale surveys: opportunities and challenges for children's geographers

This paper considers the potential contribution of secondary quantitative analyses of large scale surveys to the investigation of 'other' childhoods. Exploring other childhoods involves investigating the experience of young people who are unequally positioned in relation to multiple, embodied, identity locations, such as (dis)ability, 'class', gender, sexuality, ethnicity and race. Despite some possible advantages of utilising extensive databases, the paper outlines a number of methodological problems with existing surveys which tend to reinforce adultist and broader hierarchical social relations. It is contended that scholars of children's geographies could overcome some of these problematic aspects of secondary data sources by endeavouring to transform the research relations of large scale surveys. Such endeavours would present new theoretical, ethical and methodological complexities, which are briefly considered.

Children's sociospatial (re)production of disability within primary school playgrounds

There is a contemporary shift in the institutional context of 'disabled' children's education in the United Kingdom from segregated special to mainstream schools. This change is tied to wider deinstitutionalised or reinstitutionalised geographies of disabled people, fragile globalised educational 'inclusion' agendas, and broader concerns about social cohesiveness. Although coeducating children is expected to transform negative representations of (dis)ability in future society, there are few detailed explorations of how children's everyday sociospatial practices (re)produce or transform dominant representations of (dis)ability. With this in mind, children's contextual and shifting performances of (dis)ability in two case study school playground (recreational) spaces are explored. The findings demonstrate that children with mind-body differences are variously (dis)abled, in comparison with sociospatially shifting norms of ability, which have body, learning, and emotional-social facets. The discussion therefore places an emphasis on the need to incorporate 'intellectual' and 'emotional' differences more fully into geographical studies of disability and identity. The paper has wider resonance for transformative expectations placed on colocating children with a variety of 'axes of difference' (such as gender, 'race, ethnicity, and social class) in schools.

Evidence for an apartheid-like social structure in early Anglo-Saxon England

The role of migration in the Anglo-Saxon transition in England remains controversial. Archaeological and historical evidence is inconclusive, but current estimates of the contribution of migrants to the English population range from less than 10 000 to as many as 200 000. In contrast, recent studies based on Y-chromosome variation posit a considerably higher contribution to the modern English gene pool (50-100%). Historical evidence suggests that following the Anglo-Saxon transition, people of indigenous ethnicity were at an economic and legal disadvantage compared to those having Anglo-Saxon ethnicity. It is likely that such a disadvantage would lead to differential reproductive success. We examine the effect of differential reproductive success, coupled with limited intermarriage between distinct ethnic groups, on the spread of genetic variants. Computer simulations indicate that a social structure limiting intermarriage between indigenous Britons and an initially small Anglo-Saxon immigrant population provide a plausible explanation of the high degree of Continental male-line ancestry in England.

Determinants of fruit and vegetable intake in England: a re-examination based on quantile regression

Objective To examine die sociodemographic determinants of fruit and vegetable (F&V) consumption in England and determine the differential effects of socioeconomic variables at various parts of the intake distribution, with a special focus on severely inadequate intakes Design Quantile regression, expressing F&V intake as a function of sociodemographic variables, is employed. Here, quantile regression flexibly allows variables such as ethnicity to exert effects on F&V intake that. vary depending oil existing levels of intake. Setting The 2003 Health survey of England. Subjects Data were from 11044 adult individuals. Results The influence of particular sociodemographic variables is found to vary significantly across the intake distribution We conclude that women consume more F&V than men, Asians and Hacks mole dian Whites, co-habiting individuals more than single-living ones Increased incomes and education also boost intake However, the key general finding of the present study is that the influence of most variables is relatively weak in the area of greatest concern, i e among those with the most inadequate intakes in any reference group. Conclusions. Our findings emphasise the importance of allowing the effects of socio-economic drivers to vary across the intake distribution The main finding, that variables which exert significant influence on F&V Intake at other parts Of the conditional distribution have a relatively weak influence at the lower tail, is cause for concern. It implies that in any defined group, those consuming the lease F&V are hard to influence using compaigns or policy levers.

Uneven playing field or falling standards? Chinese students' competence in English.

This paper explores student and teacher perspectives of challenges relating to the levels of competence in English of Chinese students studying overseas from the perspective of critical pedagogy. It draws on two complementary studies undertaken by colleagues at the University of Reading. The first—a research seminar attended by representatives from a wide range of UK universities—presents the views of teachers and administrators; the second draws on four case studies of the language learning of Chinese postgraduate students during their first year of study in the UK, and offers the student voice. Interview and focus group data highlight the limitations of current tests of English used as part of the requirements for university admission. In particular, university teachers expressed uncertainty about whether the acceptance of levels of written English which fall far short of native-speaker competence is an ill-advised lowering of standards or a necessary and pragmatic response to the realities of an otherwise uneven playing field. In spite of this ambivalence, there is evidence of a growing willingness on the part of university teachers and support staff to find solutions to the language issues facing Chinese students, some of which require a more strategic institutional approach, while others rely on greater flexibility on the part of individuals. Although the studies reported in this paper were based on British universities, the findings will also be of interest to those involved in tertiary education in other English-speaking countries which are currently attracting large numbers of Chinese students.

Moderate fish-oil supplementation reverses low-platelet, long-chain n-3 polyunsaturated fatty acid status and reduces plasma triacylglycerol concentrations in British Indo-Asians

Background: The mechanisms involved in the increased mortality from coronary artery disease in British Indo-Asians are not well understood. Objectives: This study aimed to investigate whether British Indo-Asian Sikhs have higher plasma triacylglycerol concentrations, lower platelet phospholipid levels, and lower dietary intakes of long-chain n-3 polyunsaturated fatty acids (PUFAs) than do age- and weight-matched Europeans and whether moderate dietary fish-oil intake can reverse these differences. Design: A randomized, double-blind, placebo-controlled, parallel, fish-oil intervention study was performed. After a 2-wk run-in period, 44 Europeans and 40 Indo-Asian Sikhs were randomly assigned to receive either 4.0 g fish oil [1.5 g eicosapentaenoic acid (EPA) and 1.0 g docosahexaenoic acid (DHA)] or 4.0 g olive oil (control) daily for 12 wk. Results: At baseline, the Indo-Asians had significantly higher plasma triacylglycerol, small dense LDL, apolipoprotein B, and dietary and platelet phospholipid n-6 PUFA values and significantly lower long-chain n-3 PUFAs (EPA and DHA) than did the Europeans. A significant decrease in plasma triacylglycerol, plasma apolipoprotein B-48, and platelet phospholipid arachidonic acid concentrations and a significant increase in plasma HDL concentrations and platelet phospholipid EPA and DHA levels were observed after fish-oil supplementation. No significant effect of ethnicity on the responses to fish-oil supplementation was observed. Conclusions: Moderate fish-oil supplementation contributes to a reversal of lipid abnormalities and low n-3 PUFA levels in Indo-Asians and should be considered as an important, yet simple, dietary manipulation to reduce CAD risk in Indo-Asians with an atherogenic lipoprotein phenotype.
