Mouse model of Schistosomiasis: infection with Schistosoma mansoni in CD-1 mice

Schistosomiasis is a parasitic disease that affects almost 240 million worldwide. CD1 mice were infected with cercariae of S. mansoni, after which infection developed for 8 weeks. Tissues were processed to immuno-histological techniques. It was performed H&E staining for overall analyses, Sirius Red for fibrosis and immunohistochemistry for inflammation biomarkers. The most infected organ was the liver, fibrosis decreased with egg development and Galectin-3 (Gal3) and Interleukin 6 (IL-6) were expressed inside granulomasThis work was also supported by FCT – Fundação para a Ciência e Tecnologia (REF UID/BIM/04293/2013) and by the project NORTE-01-0145-FEDER-000012 and by a scholarship to Carla Luís with the reference SAICT2016/FEDER/BIO4DIA/BTI under the supervision of Dr. Rúben Fernandes.N/

Two-Dimensional Bosonization from Variable Shifts in the Path Integral

A method to perform bosonization of a fermionic theory in (1+1) dimensions in a path integral framework is developed. The method relies exclusively on the path integral property of allowing variable shifts, and does not depend on the explicit form of Greens functions. Two examples, the Schwinger model and the massless Thirring model, are worked out.Comment: 4 page

The inequality effect in the well-being of European OECD countries: a new perspective on data addressing the multidimensionality of the concepts

Social inequality refers to the uneven distribution of resources in a society that can lead to systematically and unfair advantages/disadvantages in peoples’ life circumstances and opportunities. In populations all over the world, people with fewer resources have worse chances in life, health and well-being. Additionally, inequality hinders not only the people on the bottom of the social rank, but also the general population: in more unequal societies there is a higher incidence of a wide range of health and social problems such as criminality and poverty, fewer chances of economic growth, and higher unbalances in political representation, that can seriously undermine the fairness of political and economic institutions. Despite the consistence of its implications, social inequality is not a one-dimensional construct. Addressing social inequalities, implies not only addressing the degree of concentration or dispersion of valued goods, but also the correlation among these valuable features, and their plural implications in peoples' life circumstances – a multidimensional approach of social inequality is therefore advised. We explore the well-being inequalities in Europe building upon the OECD Framework For Measuring Well-Being And Progress. In this scope, well-being is understood as a multidimensional concept, framed by material conditions, quality of life and sustainability, and expressed by eleven well-being dimensions – income and wealth, jobs and earnings, housing, health, education, work-life balance, environment, social connections, civic engagement, safety and subjective well-being. Taking European Social Survey as the main empirical source, the interplay between key distributional (education, income) and categorical (gender, social class) dimensions of social inequalities in well-being and well-being profiles was studied, under two levels of analysis of the OECD European social space – transnational (across individuals) and national (across countries). Social inequalities on well-being scores and well-being profiles were identified. Higher education, higher income, and belonging to a more privileged social class positively influence well-being; men tend to present higher well-being than women. The four well-being profiles identified among Europeans were shown to be clearly structured by social inequalities, opposing higher- and lower- qualified socio-occupations, and males and females' life circumstances (Low-wage earners well-being profile, Elite well-being profile, Female well-being profile, Male well-being profile). At a country level, profiles are mostly defined in terms of volume of well-being, expressing regional affiliations (with a exception of one profile) and asymmetries of income, education, and class structures (Nordic high-rank well-being profile; Central Europe medium-rank well-being profile; Southern Europe medium-rank well-being profile; Eastern Europe low-rank well-being profile; Social disengagement low-rank well-being profile). The developed analysis confirms the existence of multidimensional intersections between well-being and categorical and distributive social structuring variables.info:eu-repo/semantics/publishedVersio

Service quality in airport hotel chains through the lens of online reviewers

Airport hotel chains target the specific and important segment of accommodation near airports, thus benefiting from travelers seeking to stay near an airport. This study addresses service quality by analyzing TripAdvisor online reviews over units from both a high-end and a low-end chain in five European cities (Amsterdam, Brussels, Frankfurt, London, Paris). Using text mining and topic modeling, ten heat matrices were drawn (one per unit) to summarize the main services characterizing the computed topics. Seven hypotheses grounded on existing literature were tested, from which some interesting findings emerged (e.g., related to transfer services, staff, food and beverage, cleanliness, and punctuality). This study contributes to the standardization versus adaptation debate by unveiling a globalized strategy in staff management and breakfast services, while bar services adopt a localized strategy. Transportation services, while not offered by the hotels, are frequently mentioned, which signals hoteliers to interact with local authorities to improve accessibilities.info:eu-repo/semantics/acceptedVersio

The left and right hands of the Portuguese state: Welfare retrenchment of public employment

This article focuses on welfare retrenchment in Portugal by analysing the evolution of public sector employment up until 2013. A multidimensional analysis of the structure of public employment in the Portuguese state was developed, theoretically guided by the ‘hands of the state’ model proposed by Bourdieu, which divides the main functions of contemporary states between its left hand (more redistributive) and its right hand (more rational economic-oriented). Bourdieu’s approach is especially useful in addressing the transformations of the Portuguese public employment between 1979 and 2013, characterized by specific economic, social and political changes. In 2013 – a year in which the adjustment measures agreed by the Portuguese government, the European Central Bank, the European Commission and the International Monetary Fund during the global crisis were especially intense – we observed the tendency towards the disqualification of public employment and the shrinking of the left hand of the Portuguese state. Public policy orientations in the areas of education and science were particularly troubling, considering the structural backwardness the country faces in these fields in the context of the European Union.info:eu-repo/semantics/acceptedVersio
