Controls on the flow regime and thermal structure of the subduction zone mantle wedge: a systematic 2-D and 3-D investigation

Arc volcanism at subduction zones is likely regulated by the mantle wedge’s flow regime and thermal structure and, hence, numerous studies have attempted to quantify the princi- pal controls on mantle wedge conditions. In this thesis, we build on these previous studies by undertaking the first systematic 2-D and 3-D numerical investigations, across a wide parameter-space, into how hydration, thermal buoyancy and toroidal flow around the slab edge influence the wedge’s flow regime and associated thermal structure. We find that small- scale convection (SSC), resulting from Rayleigh-Taylor instabilities, or drips, off the base of the overriding lithosphere, is a typical occurrence, if: (i) viscosities are < 5 × 1018 Pa s; and (ii) hydrous weakening of wedge rheology extends at least 100-150 km from the forearc cor- ner. In 2-D models, instabilities generally take the form of ‘drips’. In 3-D, two separate, but interacting, longitudinal Richter roll systems form (with their axes aligned perpendicular to the trench), the first below the arc region and the second below the back-arc region. These instabilities result in transient and spatial temperature fluctuations of 100-150K, which are sufficient to influence melting, the stability of hydrous minerals and the dehydration of crustal material. Furthermore, they are efficient at eroding the overriding lithosphere, par- ticularly in 3-D and, thus, provide a means to explain observations of high heat flow and thin back-arc lithosphere at many subduction zones. A preliminary study into the effects of a finite-width slab on the wedge’s flow regime, which allows for toroidal flow around the slab edge, highlights that the toroidal cell can locally increase or decrease temperatures suf- ficiently to either enhance or shut down wet melting, while a hydrated wedge corner may channel trench-parallel flow. The dynamic complexities of wedge flow revealed by our mod- els may help explain the diversity in geophysical and geochemical subduction signatures.Open Acces

Sustainability and Communication in Higher Education

[EN] Sustainability Sciences need communication to communicate knowledge effectively and to engage audiences toward sustainable development. Therefore, the present study examines to what extent media and communication aspects are integrated into sustainability science's curricula of higher education institutions in Europe. For this purpose, a total of n=1117 bachelor and master's degree programs and their related curricula/program specifications from 31 European countries were analyzed by means of content analysis. Results show that the level of curricular integration of media and communication aspects in the field of sustainability science is not (yet) far advanced (18%). This leaves room for a reflection on the perceived (ir-)relevance of communication as a crucial discipline and competence in the sustainability science area, as well as on the social and educational responsibility of higher education institutions.Voci, D.; Karmasin, M.

Validation of a Food Frequency Questionnaire by food groups for the adolescent population

OBJETIVO: Verificar a validade do Questionário de Freqüência Alimentar para Adolescentes para avaliar o consumo de grupos de alimentos entre escolares de Piracicaba, São Paulo. MÉTODOS: Participaram do estudo 94 adolescentes, com idade entre 11 e 15 anos, matriculados em uma escola da rede pública. O consumo alimentar foi avaliado pelo Questionário de Freqüência Alimentar para Adolescentes (QFAA) e a média de dois Recordatórios de 24 horas (R24h) foi utilizada como método de referência. Os itens alimentares foram classificados em 18 grupos. Foram realizadas análises descritivas, teste t-Student pareado e de Wilcoxon, coeficientes de correlação de Pearson e de Spearman. Foram também utilizadas análise de quartis e estatística Kappa ponderado. Os coeficientes de correlação foram corrigidos pela variância intrapessoal dos R24h, estimada a partir de ANOVA com um fator de classificação. RESULTADOS: Não foram verificadas diferenças significativas entre os instrumentos para o arroz, massas, carnes, refrigerantes e sucos artificiais. Os coeficientes de correlação corrigidos pela variabilidade intrapessoal variaram de -0,26 a 0,78. A concordância de classificação dos indivíduos no mesmo quartil de consumo para ambos os métodos variou de 22% (massas) a 50% (feijão). Para quartis opostos, os grupos que tiveram mais de 10% dos indivíduos classificados incorretamente foram massas (19%), carnes (13%) e gorduras (11%). Os valores de Kappa ponderado variaram de - 0,15 (massas) a 0,56 (feijão). O QFAA superestimou o consumo de quase a totalidade dos grupos alimentares e subestimou os grupos dos óleos, feijão, carnes e refrigerantes. CONCLUSÃO: O instrumento apresentou boa validade para feijão, verduras e legumes, leite e derivados, biscoitos recheados e para o arroz.OBJECTIVE: To verify the validity of the Food Frequency Questionnaire for Adolescents in order to evaluate food group consumption among adolescents from Piracicaba, São Paulo. METHODS: The study was carried out with 94 adolescents, ranging from 11 to 15 years of age, from the public education system. Food consumption was assessed by the Food Frequency Questionnaire for Adolescents (QFAA) and the average of two 24-hour recalls (R24h) was used as a reference method. The food items were classified into 18 groups. Descriptive analyses, paired t-test and Wilcoxon test, Pearson and Spearman coefficients were performed. Analysis of quartiles and Kappa test were used. Correlation coefficients were adjusted by the within-subject variance of the 24-hour recalls, from one-way ANOVA. RESULTS: No significant differences were found between the tools for rice, pasta, meat, soft drinks, and artificial juices. The correlation coefficients adjusted by within-subject variability ranged from -0.26 to 0.78. Agreement of individuals' classification in quartiles of food consumption for both methods ranged from 22% (pasta) to 50% (beans). For discordant quartiles, the groups that presented more than 10% of misclassified subjects were pasta (19%), meat (13%) and fats (11%). The values of the Kappa test ranged from -0.15 (pastas) to 0.56 (beans). The food frequency questionnaire over-estimated the consumption of almost all the food groups and under-estimated the groups of oils, beans, meats, and soft drinks CONCLUSION: The food frequency questionnaire revealed good validity for beans, vegetables, milk and dairy, cookies with filling, and rice.FAPES

The Effects of Immigrant Consumption Experience Abroad in the Education of Albanian Consumption According to International Gusto and Standards

Going international for a national economy in an increasingly globalization process does not mean just thinking how to export products and services. First, you have to create and implement international standards for the home country products and services. The process of internationalization is an integral process, affecting culture, politics, economy and way of living as well. Going international for an economy is a very broad issue but the way we refer in this paper is very closely related to the living standards of the people and more specifically of the immigrant communities between the host country and the country of origin. There are different ways of rising up and establishing international standards in consumption in the domestic market, one of which sounds to be smooth and very natural considering the transformation process. Consumption is part of the culture and so is the way of living. This means that it should be a long process to adopt international standards of consumption in the internal market. But it is not the same when we consider immigrants and their relatives have intense exchange of experiences with them, and the fact that immigrants are bicultural. They naturally can ‘import’ their second culture elements and standards home. The positive effects of this phenomenon which comes as a result of the process of education of the domestic market from the immigrant consumption experience abroad directly impacts the home market demand for consumption according to the international gusto and standards. Albanian immigrant group have been for many years, and still are very important enclave for the internationalization of our economy, as they represent more than 1/3 of our total population. Having into consideration this fact, the goal of this paper is to analyze the consequences that the domestic market, goods and services, have had so far and how the production standards have evolved.

Do coxibs reduce prescription of gastroprotective agents? Results of a record linkage study

BACKGROUND: Coxibs are claimed to be cost-effective drugs and reduced prescription of gastroprotective agents is assumed to be one of their major benefits. Real life prescription of these drugs may be substantially different than that considered in pharmacoeconomic analyses or claimed by drug companies, yet. Our objective was to evaluate whether coxibs were associated with reduced prescription of gastro-protective agents (GPAs, specifically proton pump inhibitors, H(2 )blockers and misoprostol) compared to non selective NSAIDs. METHODS: A record-linkage study was performed using 2001 outpatient prescription data from the province of Modena (about 632,000 inhabitants, in Northern Italy). Logistic regression was used to calculate the odds ratio of GPA prescription for coxib and non-selective NSAID adult users (> 14 years). Three categories of users were further investigated: "acute", "chronic and "incident or new". Main outcome measures were same-day co-prescription and 30 days prescription of GPAs in coxibs and non selective NSAIDs users. To limit selection bias, data were adjusted for age, sex, DDD of coxibs and non selective NSAIDs received during 2001, DDD of GPAs and (for non-incident users) DDD of NSAIDs received during the previous 4 years RESULTS: Same day co-prescription rates were similar considering the overall population and "acute" users. Chronic coxibs users instead showed higher co-prescription rates than chronic NSAIDs users (OR = 1.2, p < 0.05). GPA prescription within thirty days was also higher among all subgroups of coxibs users (OR ranging from 1.6 to 2.0, p < 0.001). CONCLUSION: Assumptions made in pharmacoeconomic analyses on coxibs (lower GPA prescription associated with coxibs use) may be overly optimistic. Claims made through cost-effectiveness data should be carefully interpreted, and mechanisms for attributing drug prices revised accordingly
