Interdisciplinary research for the analysis and risk assesment : the case of the municipality of Uspantan Guatemala

Short description of the proposed presentation * lees than 100 words This paper describes the interdisciplinary work done in Uspantán, Guatemala, a city vulnerable to natural hazards. We investigated local responses to landslides that happened in 2007 and 2010 and had a strong impact on the local community. We show a complete example of a systemic approach that incorporates physical, social and environmental aspects in order to understand risks. The objective of this work is to present the combination of social and geological data (mapping), and describe the methodology used for identification and assessment of risk. The article discusses both the limitations and methodological challenges encountered when conducting interdisciplinary research. Describe why it is important to present this topic at the Global Platform in less than 50 words This work shows the benefits of addressing risk in an interdisciplinary perspective, in particular how integrating social sciences can help identify new phenomena and natural hazards and assess risk. It gives a practical example of how one can integrate data from different fields. What is innovative about this presentation? * The use of mapping to combine qualitative and quantitative data. By coupling approaches, we could associate a hazard map with qualitative data gathered by interviews with the population. This map is an important document for the authorities. Indeed, it allows them to be aware of the most dangerous zones, the affected families and the places where it is most urgent to intervene.

Tests pharmacogénétiques: bientôt avant chaque prescription [Pharmacogenetic testing: soon before every prescription?]

Genetic polymorphisms have currently been described in more than 200 systems affecting pharmacological responses (cytochromes P450, conjugation enzymes, transporters, receptors, effectors of response, protection mechanisms, determinants of immunity). Pharmacogenetic testing, i.e. the profiling of individual patients for such variations, is about to become largely available. Recent progress in the pharmacogenetics of tamoxifen, oral anticoagulants and anti-HIV agents is reviewed to discuss critically their potential impact on prescription and contribution/limits for improving rational and safe use of pharmaceuticals. Prospective controlled trials are required to evaluate large-scale pharmacogenetic testing in therapeutics. Ethical, social and psychological issues deserve particular attention.

As Línguas de Cabo Verde: uma Radiografia Sociolinguística

Esta dissertação constitui um estudo de caso, exploratório e de carácter descritivo. Tem como objectivo fazer uma radiografia sociolinguística de Cabo Verde, particularmente centrada no actual uso das duas línguas faladas no arquipélago, o português (PCV) e o crioulo cabo-verdiano (LCV). A linha de pesquisa adoptada inspira-se fortemente nos estudos de macrosociolinguística, tomando a situação de contacto de línguas, caracterizadora da sociedade cabo-verdiana, como ponto de partida para o enquadramento de um conjunto de questões seleccionadas para investigação mais aprofundada. São, assim, explorados os processos implicados nesta situação de contacto concreta e os resultados linguísticos decorrentes da mesma, como o bilinguismo ou a diglossia (cf. Cap. 3). Recorrendo a contributos teóricos de áreas associadas e complementares (cf. Cap. 1), foca-se a importância da análise dos domínios em que cada uma das línguas é usada, das redes sociais dos falantes ou das suas atitudes linguísticas. A investigação partiu de uma recolha de dados realizada para o efeito, nas nove ilhas habitadas. As unidades de análise retidas correspondem a uma amostragem de dois grupos sociais distintos: falantes jovens, alunos do ensino secundário (inquiridos por questionário), e falantes adultos cuja profissão implica uma intensa actividade linguística (professores e ‘líderes’, inquiridos por entrevistas semi-dirigidas). Foi usada uma metodologia de recolha o mais rigorosa possível e adoptado o tratamento estatístico de dados (cf. Cap. 2). O confronto dos comportamentos linguísticos e das atitudes das duas gerações inquiridas, com diferentes características (cf. Introdução), forneceu importantes informações sobre a dinâmica linguística da sociedade cabo-verdiana, conclusões essas que serão importantes para a definição de orientações no âmbito da política linguística (cf. Cap. 5). É apresentada, como complemento, uma análise exploratória de alguns aspectos sintácticos atestados nas produções dos indivíduos inquiridos com instrução superior (cf. Cap. 4), um contributo, embora modesto, para a definição da variedade padrão do PCV

Endogenous constitutions

We present a theory of the choice of alternative democratic constitutions, a majoritarian or a consensual one, in an unequal society. A majoritarian democracy redistributes resources from the collectivity toward relatively few people, and has a relatively small government and low level of taxation. A consensual democracy redistributes resources toward a broader spectrum of social groups but also has a larger government and a higher level of taxation. We show that a consensual system turns out to be preferred by society when ex ante income inequality is relatively low, while a majoritarian system is chosen when income inequality is relatively high. We also obtain that consensual democracies should be expected to be ruled more often by center-left coalitions while the right should have an advantage in majoritarian constitutions. The implications for the relationship between inequality and redistribution are discussed. Historical evidence and a cross-sectional analysis support our results.

IRELAND AND LATIN AMERICA: A CULTURAL HISTORY

According to Declan Kiberd, “postcolonial writing does not begin only when the occupier withdraws: rather it is initiated at that very moment when a native writer formulates a text committed to cultural resistance.” The Irish in Latin America – a continent emerging from indigenous cultures, colonisation, and migrations – may be regarded as colonised in Ireland and as colonisers in their new home. They are a counterexample to the standard pattern of identities in the major English-speaking destinations of the Irish Diaspora. Using literary sources, the press, correspondence, music, sports, and other cultural representations, in this thesis I search the attitudes and shared values signifying identities among the immigrants and their families. Their fragmentary and wide-ranging cultures provide a rich context to study the protean process of adaptation to, or rejection of, the new countries. Evolving from oppressed to oppressors, the Irish in Latin America swiftly became ingleses. Subsequently, in order to join the local middle classes they became vaqueros, llaneros, huasos, and gauchos so they could show signs of their effective integration to the native culture, as seen by the Latin American elites. Eventually, some Irish groups separated from the English mainstream culture and shaped their own community negotiating among Irishness, Englishness, and local identities in Brazil, Uruguay, Peru, Cuba, and other places in the region. These identities were not only unmoored in the emigrants’ minds but also manoeuvred by the political needs of community and religious leaders. After reviewing the major steps and patterns of Irish migration to Latin America, the thesis analyses texts from selected works, offers a version of how the settlers became Latin Americans or not, and elucidates the processes by which a new Irish-Latin American hybrid was created.

Experimental manipulation of colony genetic diversity had no effect on short-term task efficiency in the Argentine ant Linepithema humile

Genetic diversity might increase the performance of social groups by improving task efficiency or disease resistance, but direct experimental tests of these hypotheses are rare. We manipulated the level of genetic diversity in colonies of the Argentine ant Linepithema humile, and then recorded the short-term task efficiency of these experimental colonies. The efficiency of low and high genetic diversity colonies did not differ significantly for any of the following tasks: exploring a new territory, foraging, moving to a new nest site, or removing corpses. The tests were powerful enough to detect large effects, but may have failed to detect small differences. Indeed, observed effect sizes were generally small, except for the time to create a trail during nest emigration. In addition, genetic diversity had no statistically significant impact on the number of workers, males and females produced by the colony, but these tests had low power. Higher genetic diversity also did not result in lower variance in task efficiency and productivity. In contrast to genetic diversity, colony size was positively correlated with the efficiency at performing most tasks and with colony productivity. Altogether, these results suggest that genetic diversity does not strongly improve short-term task efficiency in L. humile, but that worker number is a key factor determining the success of this invasive species.

Propuesta de un sistema de indicadores ambientales y socio económicos en la zona marino costera de Pisco - Paracas

Se presenta un breve diagnóstico de los aspectos ambientales, sociales y económicos del área marino costera de Pisco Paracas, cuya bahía forma parte de la zona de amortiguamiento de la Reserva Nacional de Paracas. A pesar de la importancia y fragilidad del ecosistema, y su proximidad en la zona de amortiguamiento de la Reserva, se ha permitido el asentamiento y desarrollo de diversas actividades extractivas, productivas con el consiguiente incremento en el tráfico marítimo. Diversos programas de vigilancia y seguimiento de entidades públicas o multisectoriales se han realizado en la zona, pero sin un enfoque más integral sobre las interacciones que se dan en un medio tan sui géneris como el medio marino Pisco-Paracas . Se realiza un análisis de la data histórica de los parámetros físico químicos de calidad acuática del período 2000-2010, obtenido principalmente de los programas de seguimiento o evaluación que realiza IMARPE y la empresa PLUS PETROL, contrastándolo con los valores ECA – Categoría 4 (DS 02-2008 – MINAM) a fin de determinar si ellos constituyen indicadores apropiados para determinar el estado real del ecosistema marino costero de Pisco – Paracas. La actual legislación de los recursos hídricos, no es muy clara ni precisa sobre la aplicabilidad para el control de los ECA‟ s en el ámbito marino; esta falta de precisión no contribuye a una vigilancia más eficiente. Con relación a ello, se alcanza una propuesta del sistema de indicadores que incluye parámetro biológico, como la determinación de las floraciones algales nocivas (FAN), episodios recurrentes en Pisco – Paracas; así mismo se introduce el tema de indicadores que midan el cambio en el ecosistema marino, con un enfoque más integral en la zona de Pisco – Paracas tan sujeta a cambios de origen climático

Soil uses in the sugarcane fallow period to improve chemical and physical properties of two latosols (oxisols)

Sugarcane production should be integrated with crop diversification with a view to competitive and sustainable results in economic, social and environmental aspects. The purpose of this study was to assess the influence of different soil uses during the sugarcane fallow period on the chemical and physical properties of eutroferric Red Latosol - LVef (Oxisol) and Acric Latosol - LVw (Acric Oxisol), in Jaboticabal, São Paulo State, Brazil (21º14'05'' S, 48º17'09'' W, 600 m asl). A randomized block design was used with five replications and four treatments, consisting of different soil uses (crops) in the sugarcane fallow period: soybean only, soybean/fallow/soybean, soybean/millet/soybean, and soybean/sunn hemp/soybean. After two soybean crops, the LVef chemical properties remained at intermediate to high levels; while those of the LVw, classified as intermediate to high in the beginning, increased to high levels. Thus, the different soil uses during the sugarcane fallow period allowed the maintenance of LVef fertility levels and the improvement of those of the LVw. Two soybean crops increased macroporosity in the 0.0-0.1 m layer of the LVef; reduced soil aggregates in the 0.0-0.1 and 0.1-0.2 m layers of both soils, and reduced aggregate stability in these two layers of the LVw. Planting pearl millet or sunn hemp between the two soybean growing seasons promoted the formation of larger soil aggregates in the surface layer (0.0-0.1 m) of the LVw.

Experimentally increased group diversity improves disease resistance in an ant species.

A leading hypothesis linking parasites to social evolution is that more genetically diverse social groups better resist parasites. Moreover, group diversity can encompass factors other than genetic variation that may also influence disease resistance. Here, we tested whether group diversity improved disease resistance in an ant species with natural variation in colony queen number. We formed experimental groups of workers and challenged them with the fungal parasite Metarhizium anisopliae. Workers originating from monogynous colonies (headed by a single queen and with low genetic diversity) had higher survival than workers originating from polygynous ones, both in uninfected groups and in groups challenged with M. anisopliae. However, an experimental increase of group diversity by mixing workers originating from monogynous colonies strongly increased the survival of workers challenged with M. anisopliae, whereas it tended to decrease their survival in absence of infection. This experiment suggests that group diversity, be it genetic or environmental, improves the mean resistance of group members to the fungal infection, probably through the sharing of physiological or behavioural defences.

Estudio exprimental del bilinguismo: revisión histórica I

En el presente trabajo se lleva a cabo una revisión histórica de los estudios realizados sobre el bilingiiismo, concretándose, fundamentalmente, en las dos grandes hipótesis teóricas en torno al mismo. Se analizan, a continuación, las investigaciones que apoyan tanto a la hipótesis de "sistemas lingiiisticos separados" como a la hipótesis de un "único sistema". Por último se hace una presentación de los trabajos que han sido más relevantes en la investigación actual. De esta forma se presentan los estudios de carácter psicofisiológico, la relación entre bilingiiismo y psicologia cognitiva, la medición del bilingüismo y la teoria del código dual aplicado al bilingüismo. El texto termina planteando una serie de consideraciones de carácter metodológico y la propuesta de un modelo que va a ser objeto de un segundo escrito sobre dicha temática.

Perceptions of diabetes obtained through drawing in childhood and adolescence

Objective: To examine whether drawing is useful in the detection of problems of psychosocial adaptation in children and adolescents with type 1 diabetes (T1D) and in improving communication with health professionals. Methods: We performed an exploratory descriptive study in 199 children and adolescents with T1D aged 413 years. The participants were asked to render a drawing on a suggested topic. The variables analyzed were related to the drawing and to clinical and sociodemographic data. Results: Most participants showed evidence of having a well-balanced personality, but there were also signs of affective or psychosocial difficulties. Conclusion: Drawing is a useful technique by which to identify children"s and adolescents" feelings and possible problems in adapting to T1D, as well as to gain information directly from the children themselves. Future studies should delimit the possibilities of this technique in clinical practice in greater detail.
