When extremely poor and excluded populations are concerned, Multi-Situated Ethnography (MSE) represents a valuable research design for health needs and resources diagnosis* and for the improvement of health promotion programmes. By focusing on the results of our 2-years community-based participatory study on prevention amongst Roma populations living in France**, we will assess the potentials of ethnography-based research for both scientific production and health promotion interventions. Methods/actions. A MSE has been carried in three distinct scenarios, selected because of the different socio-cultural integration levels and life conditions of the Roma families. There are: 1) the Forest of Mery-sur-Oise, a shanty town where around twenty Roma families live, 2) the collective emergency housing in the old headquarters in Saint-Maur-des-Fossé, and 3) S.A.N. de Sénart, a conglomeration of towns which an integration plan of Roma people was launched in. This fieldwork has produced scientific data on the healthcare provision and the social accompaniment realised by professionals of the health, social and administrative sectors as well as on Roma’s health promotion practices. A reflexive evaluation design was undertaken through the conduction of an expert panel involving 3 sociologists and 3 social workers, meeting each month. Results. The MSE allowed building up comparative relations between health practices and socio-economic and geo-political factors amongst “hermetical populations” when they asked to share information on their life with outsiders. Simultaneously, the data analysis allowed considering: universal similarities, cultural differences and individual singularities. The increased of the methodological procedures as it helped avoid falling into stigma reification of groups already highly racially discriminated. Its participatory dimension helped document and share learning across contexts, providing a renewed source of dynamism amongst professionals dealing with sensitive fields and very difficult to access. Because of the sensitivity brought by its in-depth comprehensive-based approach, it moved closer professionals to their Roma beneficiaries, even leading to cases of conflict resolution between both actors. Conclusion. The acquisition of the required skills to carry out a social and health intervention based on a community-based participatory diagnostic of needs and resources and, on an evaluative follow-up of the actions undertaken within the intervention scenario is a major asset for the elaboration and management of individual or community-dimensioned professional projects. MSE needs to be revisited and revalued as it comprises useful a set of competences to give informed guidance by supplying decision-makers and professionals, with sound and comprehensive analysis.

Mobile Crowdsensing (MCS) has emerged in the last years and has become one of the most prominent paradigms for urban sensing. The citizens actively participate in the sensing process by contributing data with their mobile devices. To produce data, citizens sustain costs, i.e., the energy consumed for sensing and reporting operations. Hence, devising energy efficient data collection frameworks (DCF) is essential to foster participation. In this work, we investigate from an energy-perspective the performance of different DCFs. Our methodology is as follows: (i) we developed an Android application that implements the DCFs, (ii) we profiled the energy and network performance with a power monitor and Wireshark, (iii) we included the obtained traces into CrowdSenSim simulator for large-scale evaluations in city-wide scenarios such as Luxembourg, Turin and Washington DC. The amount of collected data, energy consumption and fairness are the performance indexes evaluated. The results unveil that DCFs with continuous data reporting are more energy-efficient and fair than DCFs with probabilistic reporting. The latter exhibit high variability of energy consumption, i.e., to produce the same amount of data, the associated energy cost of different users can vary significantly. [less ▲]

Even though intra-European youth mobility is valued as a boost for personal and professional development, few opt for it. While obstacles preventing young people to become mobile have been discussed broadly, less attention has been paid to the obstacles for the youth who are already on the move. We offer this rare perspective in regard to intra-European mobility. We focus on youth in four types: pupil mobility, vocational (education and training) mobility, higher education student (degree and credit) mobility and employment mobility, in six countries: Germany, Hungary, Luxembourg, Norway, Romania and Spain. Our analysis, based on qualitative (140 interviews) and quantitative (N=1.682) data, reveals that the perceived obstacles vary between the mobility types, with the greatest divergence between the educational and work-related mobilities. Obstacles such as lack of financial resources and guidance, the perceived incompatibility of institutional regulations within Europe, are shared by all mobile youth. [less ▲]

While life satisfaction (LS) promotes the health of cardiovascular patients, LS may be affected by a range of primary and secondary determinants. We analysed LS and its relationships with cardiovascular risk factors and unhealthy behaviours. Methods. In 2013, 3,632 survivors who underwent coronary angiography in 2008-2009 at the Luxembourgish National Institute of Cardiac Surgery and Cardiological Intervention (INCCI), living at home were asked to estimate, five years after, their LS [1-10] and other health-related variables. Data were analysed via multiple regression models including interaction effects. Findings. LS of the 1,289 participants (age: 69.2±11.1) was 7.3/10. Most were men, employees or manual workers, had secondary education and a 36,000€ or more/year income. The interactions between hypercholesterolemia and hypertension (regression coefficient= 0.628) and with smoking (rc= 0.941) were positively related with LS, but physical inactivity was negatively associated (rc= -0.630). Discussion. Taking medications or maintaining tobacco consumption produces better LS than being ambivalent towards physical activity. Further research is needed to evaluate the efficacy of health interventions eliciting and promoting the behaviour change wheel based on capabilities, opportunities, and motivations. [less ▲]

Doping liquid crystals with gold nanoparticles increases the conductivity by up to three orders of magnitude, an increase even stronger than expected for equimolar amounts of organic electrolytes. Despite recent high activity in the field of liquid crystalline nanocomposites, the origin of this increase has rarely been addressed and is not well understood. In this dielectric spectroscopy study we discuss the origin of the increased conductivity and identify its source. We demonstrate that the hydrodynamic radius of the mobile charge carrier species in nanoparticle dispersions is significantly smaller than the 3–5 nm gold core, which rules out the particles themselves to be the source of conductivity. Likewise, also the ligand molecules from the organic capping layer do not themselves add to the conductivity of the dispersions, but affect the electrical properties by acting as a trap for ionic impurities. We suggest that the partial release of these impurities upon interactions of the ligand shell with the uniaxial nematic host phase is the most likely source for the increased conductivity. Our study opens a new perspective on synthesis strategies for functionalized nanoparticles and will help to overcome the current issues preventing high-performing liquid crystal nanodispersions.

The Sustainable Development Goals (SDGs) re-focused development cooperation on universal and transformative development aimed at improving the quality of life of people in all world regions, while simultaneously conserving natural resources. Critics, however, have correctly questioned whether appropriate policy methods and tools exist for the adequate implementation of transformative development. These challenges are even more significant given that the implementation of the SDGs falls to nation-states. This article asks “Can the transformative development promoted by the SDG’s be achieved through the policy tools presently utilized by nation-states, such as environmental impact assessment (EIA)?” The study responds to this question through a critical examination of EIA in Mexico in relation to mining. Empirical analysis focuses on the proposed Caballo Blanco open-pit mine in Veracruz state. The case can be considered critical because it is often presented as a success, given that a broad coalition of actors prevented the mine from opening through activities directed at EIA. This article questions this narrative because it shows how EIA actually can undermine transformative development through the use of cost-benefit logics. The article concludes that policy coherence for development (PCD) can potentially support EIA as a methodology through which transformative development can be promoted. PCD can improve the “normative effectiveness” of EIA when used as an evaluation criteria. Otherwise, EIA may undermine the implementation of the SDGs which would be comparable to serving soup with a fork. [less ▲]
