Activism and participation among people of migrant background : discourses and practices of inclusiveness in four italian cities

Alors que l’intérêt pour les processus d’intégration des immigrants et des minorités ethniques est en pleine croissance parmi les chercheurs européens, les facteurs qui expliquent les différentes formes de participation civique et politique doivent être examinés plus en profondeur. Prenant pour base la littérature sur l’immigration, cette étude examine la question de recherche suivante: Comment peut-on expliquer les variations des formes de participation civique et politique des activistes issus de l’immigration au niveau local? Afin de répondre à cette question, cette étude identifie les formes de participation de la part d’activistes issus de l’immigration dans quatre villes Italiennes et examine les discours et les pratiques de multiples acteurs impliqués dans le domaine de l’immigration dans un contexte national d’hostilité croissante. Cette thèse soutient que pour comprendre différentes formes de participation, il est important de considérer non seulement l’État et les acteurs institutionnels, mais aussi les acteurs non-institutionnels et examiner comment ces derniers influencent les opportunités ainsi que les restrictions à la participation. Par ailleurs, cette recherche examine les canaux conventionnels et non-conventionnels dans quatre villes italiennes et étudie les activistes issus de l’immigration comme des acteurs politiques pertinents, capables de se mobiliser et d’influencer la participation à travers leur interaction et alliances avec les acteurs de la société d’accueil. Cette recherche a permis de produire trois résultats. Le premier montre que les approches d’intégration adoptées par les acteurs sont importantes. Cette étude a identifié trois approches d’intégration: 1) « welfariste », basée sur l’idée que les immigrants sont dans le besoin et doivent donc recevoir des services; 2) interculturelle, basée sur l’idée que les immigrants sont de futurs citoyens et que l’intégration est réciproque; 3) promotion des droits politiques, basée sur l’idée que les immigrants ont des droits politiques fondamentaux ; et qui encourage l’ouverture des canaux de participation politique, surtout aux immigrants privés du droit de vote local. L’analyse empirique démontre que, alors que l’approche welfariste n’encourage pas la participation parce qu’elle conçoit les immigrants comme des acteurs passifs, les autres deux approches ont respectivement un impact sur les formes de participation civique et politique. La deuxième conclusion souligne le rôle des acteurs de gauche. En particulier, cette étude montre que les acteurs qui ouvrent de canaux pour la participation ne sont pas uniquement les acteurs de gauche modérée, comme les autorités locales, les partis politiques et les syndicats, mais aussi les groupes de gauche radicale et non-institutionnelle. Chaque acteur de gauche comprend et agit différemment par rapport aux sujets de l’immigration et de la participation et ce fait influence comment les activistes issues de l’immigration se mobilisent. La troisième conclusion met en évidence le rôle de la perception des opportunités par les activistes issus de l’immigration et la façon avec laquelle ils s’approprient les discours et les pratiques des acteurs de gauche. Ce travail démontre que l’ouverture de canaux est possible grâce à l’engagement de personnes issues de l’immigration qui agissent à travers les opportunités qui leurs sont offertes, créent des alliances avec la gauche et défient les discours et pratiques des acteurs locaux.

A facile and single pot strategy for the synthesis of novel naphthyridine derivatives under microwave irradiation conditions using ZnCl2 as catalyst, evaluation of AChE inhibitory activity, and molecular modeling studies

A series of novel naphthyridine derivatives 3 and 4 was prepared from substituted pyridine 2 and ketones using ZnCl2 as catalyst under microwave irradiation conditions. All the compounds were evaluated for AChE inhibitory activity and promising compounds 3d, 3e, 4b, and 4g was identified. Representative compounds 3d and 3e were found to show insignificant THLE-2 liver cell viability/toxicity. The binding mode between X-ray crystal structure of human AChE and compounds was studied using molecular docking method and fitness scores were found to be in good correlation with the activity data.

System Design: UML Activity and Sequence Diagrams

In this session we look at how to model flow of control and interactions between components using UML Activity and Sequence Diagrams. This is an introductory session and so for Activity Diagrams we only cover branching, forks and joins and swim lanes, and for Sequence we cover lifelines, messages and returns, and alt, par and opt frames.

Predicting sense of community and participation by applying machine learning to open government data

Community capacity is used to monitor socio-economic development. It is composed of a number of dimensions, which can be measured to understand the possible issues in the implementation of a policy or the outcome of a project targeting a community. Measuring community capacity dimensions is usually expensive and time consuming, requiring locally organised surveys. Therefore, we investigate a technique to estimate them by applying the Random Forests algorithm on secondary open government data. This research focuses on the prediction of measures for two dimensions: sense of community and participation. The most important variables for this prediction were determined. The variables included in the datasets used to train the predictive models complied with two criteria: nationwide availability; sufficiently fine-grained geographic breakdown, i.e. neighbourhood level. The models explained 77% of the sense of community measures and 63% of participation. Due to the low geographic detail of the outcome measures available, further research is required to apply the predictive models to a neighbourhood level. The variables that were found to be more determinant for prediction were only partially in agreement with the factors that, according to the social science literature consulted, are the most influential for sense of community and participation. This finding should be further investigated from a social science perspective, in order to be understood in depth.

Students’ movement and participation in Latin-American psychology: historical and future perspectives

The historiographical paper presented is about the students’ activism and participation in the Latin American psychology. This aims are: 1) to provide a brief historic overview of the Latin American psychology; 2) to review on the students’ participation in the Latin American psychology; 3) to raise students’ future perspectives for the Latin American psychology. It is recognized that there is an extensive past of Latin American psychology and an emerging historiographical work that re fl ects that past.However, there are several historiographical gaps not covered yet by the investigations in the region. In this context, this paper wants to contribute to the study of the students’ activism and participation in the Latin American psychology construction. The historical perspective is supported by the renewed historiographical conception called instant history” which focuses on ancient and recent history at the same time. Indirect sources were used: articles, monographs and compiled editions.

Impact of chlorophenols and heavy metals on soil microbiota: their effects on activity and community composition, and resistant strains with potential for bioremetiation

Pollution by toxic compounds is one of the most relevant environmental damages to ecosystems produced by human activity and, therefore, it must be considered in environmental protection and restoration of contaminated sites. According to this purposes, the main goal of this doctoral thesis has been to analyse the impact of several chlorophenols and heavy metals on the microbial communities of two typical Mediterranean soils. The ecological risk concentrations of each pollutant, which have been determined according to respirometric activity and changes in the microbial community composition, and the factors that influence on their effective toxic concentrations (bioavailable pollutants) have been analysed in order to predict their potential impact on different soil ecosystems and provide scientific data for the regulation of the soil protection policies. Moreover, resistant microorganisms with pollutant removal capacities have been isolated from artificially contaminated soil microcosms and tested in axenic cultures, to infer their potential usefulness for bioremediation.

Mid-term Evaluation of the 2009-14 European Parliament: Legislative activity and decision-making dynamics. CEPS Special Report, 23 July 2012

This special report analyses legislative activity in the European Union and coalition formation in the European Parliament (EP) during the first half of the 7th legislative term, 2009-14. Co-decision is now the ordinary legislative procedure, not by name only: it was deployed on 90% of new proposals in 2010 and 86% in 2011, which suggests that the EP is now more influential than ever. There are differences in the degree of empowerment across committees, however. This report looks at the legislative workload of selected committees as an indicator of change in their influence, identifying which of them won and which lost out in terms of the quantity and type of legislation they tackle.

Use of an artificial root to examine the influence of 8-hydroxyquinoline on soil microbial activity and bacterial community structure

Invasive plant species have been shown to alter the microbial community composition of the soils they invade and it is suggested that this below-ground perturbation of potential pathogens, decomposers or symbionts may feedback positively to allow invasive success. Whether these perturbations are mediated through specific components of root exudation are not understood. We focussed on 8-hydroxyquinoline, a putative allelochemical of Centaurea diffusa (diffuse knapweed) and used an artificial root system to differentiate the effects of 8-hydroxyquinoline against a background of total rhizodeposition as mimicked through supply of a synthetic exudate solution. In soil proximal (0-10 cm) to the artificial root, synthetic exudates had a highly significant (P < 0.001) influence on dehydrogenase, fluorescein diacetate hydrolysis and urease activity. in addition, 8-hydroxyquinoline was significant (p = 0.003) as a main effect on dehydrogenase activity and interacted with synthetic exudates to affect urease activity (p = 0.09). Hierarchical cluster analysis of 16S rDNA-based DGGE band patterns also identified a primary affect of synthetic exudates and a secondary affect of 8-hydroxyquinoline on bacterial community structure. Thus, we show that the artificial rhizosphere produced by the synthetic exudates was the predominant effect, but, that the influence of the 8-hydroxyquinoline signal on the activity and structure of soil microbial communities could also be detected.

Selective effects of Lactobacillus casei Shirota on T cell activation, natural killer cell activity and cytokine production

Modulation of host immunity is an important potential mechanism by which probiotics confer health benefits. This study was designed to investigate the effects of a probiotic strain, Lactobacillus casei Shirota (LcS), on immune function, using human peripheral blood mononuclear cells (PBMC) in vitro. In addition, the role of monocytes in LcS-induced immunity was also explored. LcS promoted natural killer (NK) cell activity and preferentially induced expression of CD69 and CD25 on CD8+ and CD56+ subsets in the absence of any other stimulus. LcS also induced production of IL-1β, IL-6, TNF-α, IL-12 and IL-10 in the absence of lipopolysaccharide (LPS). In the presence of LPS, LcS enhanced IL-1β production, but inhibited LPS-induced IL-10 and IL-6 production, and had no further effect on TNF-α and IL-12 production. Monocyte-depletion significantly reduced the impact of LcS on lymphocyte activation, cytokine production and NK cell activity. In conclusion, LcS preferentially activated cytotoxic lymphocytes in both the innate and specific immune system, which suggests that LcS could potentiate the destruction of infected cells in the body. LcS also induced both pro-inflammatory and anti-inflammatory cytokine production in the absence of LPS, but inhibited LPS-induced cytokine production in some cases. Monocytes play an important role in LcS-induced immunological responses.

Modelling the lava dome extruded at Soufrière Hills Volcano, Montserrat, August 2005–May 2006. Part II: Rockfall activity and talus deformation

During many lava dome-forming eruptions, persistent rockfalls and the concurrent development of a substantial talus apron around the foot of the dome are important aspects of the observed activity. An improved understanding of internal dome structure, including the shape and internal boundaries of the talus apron, is critical for determining when a lava dome is poised for a major collapse and how this collapse might ensue. We consider a period of lava dome growth at the Soufrière Hills Volcano, Montserrat, from August 2005 to May 2006, during which a 100 × 106 m3 lava dome developed that culminated in a major dome-collapse event on 20 May 2006. We use an axi-symmetrical Finite Element Method model to simulate the growth and evolution of the lava dome, including the development of the talus apron. We first test the generic behaviour of this continuum model, which has core lava and carapace/talus components. Our model describes the generation rate of talus, including its spatial and temporal variation, as well as its post-generation deformation, which is important for an improved understanding of the internal configuration and structure of the dome. We then use our model to simulate the 2005 to 2006 Soufrière Hills dome growth using measured dome volumes and extrusion rates to drive the model and generate the evolving configuration of the dome core and carapace/talus domains. The evolution of the model is compared with the observed rockfall seismicity using event counts and seismic energy parameters, which are used here as a measure of rockfall intensity and hence a first-order proxy for volumes. The range of model-derived volume increments of talus aggraded to the talus slope per recorded rockfall event, approximately 3 × 103–13 × 103 m3 per rockfall, is high with respect to estimates based on observed events. From this, it is inferred that some of the volumetric growth of the talus apron (perhaps up to 60–70%) might have occurred in the form of aseismic deformation of the talus, forced by an internal, laterally spreading core. Talus apron growth by this mechanism has not previously been identified, and this suggests that the core, hosting hot gas-rich lava, could have a greater lateral extent than previously considered.

Antioxidant activity and protective effects of green and dark coffee components against human low density lipoprotein oxidation

The in vitro antioxidant activity and the protective effect against human low density lipoprotein oxidation of coffees prepared using different degrees of roasting was evaluated. Coffees with the highest amount of brown pigments (dark coffee) showed the highest peroxyl radical scavenging activity. These coffees also protected human low-density lipoprotein (LDL) against oxidation, although green coffee extracts showed more protection. In a different experiment, coffee extracts were incubated with human plasma prior to isolation of LDL particles. This showed, for the first time, that incubation of plasma with dark, but not green coffee extracts protected the LDL against oxidation by copper or by the thermolabile azo compound AAPH. Antioxidants in the dark coffee extracts must therefore have become associated with the LDL particles. Brown compounds, especially those derived from the Maillard reaction, are the compounds most likely to be responsible for this activity.
