Social perceptions of floods and flood management in a Mediterranean area (Costa Brava, Spain)

Taking as an example three study cases in the Costa Brava area, this paper examines the social perceptionof floods through surveys, interviews and Focus Group sessions. Perception is then related to vulnerability, flood management, and citizen’s preferences regarding alternatives to curb flood losses in the future. The study concludes that flood awareness and the willingness to take actions regarding this hazard are clearly related to the degree of social involvement with the affairs of the local community. Furthermore, participatory settings such as Focus Group sessions appear to enable a better environment for assessing and implementing flood management options that attempt to modify human activities rather than modify natural processes as has been frequently the case in the past

Internal test sets studies in a group of antimalarials

Topological indices have been applied to build QSAR models for a set of 20 antimalarial cyclic peroxy cetals. In order to evaluate the reliability of the proposed linear models leave-n-out and Internal Test Sets (ITS) approaches have been considered. The proposed procedure resulted in a robust and consensued prediction equation and here it is shown why it is superior to the employed standard cross-validation algorithms involving multilinear regression models

Diversity of the bacterial community in the surface soil of a pear orchard based on 16S rRNA gene analysis

A cultivation-independent approach based on polymerase chain reaction (PCR)-amplified partial small subunit rRNA genes was used to characterize bacterial populations in the surface soil of a commercial pear orchard consisting of different pear cultivars during two consecutive growing seasons. Pyrus communis L. cvs Blanquilla, Conference, and Williams are among the most widely cultivated cultivars in Europe and account for the majority of pear production in Northeastern Spain. To assess the heterogeneity of the community structure in response to environmental variables and tree phenology, bacterial populations were examined using PCR-denaturing gradient gel electrophoresis (DGGE) followed by cluster analysis of the 16S ribosomal DNA profiles by means of the unweighted pair group method with arithmetic means. Similarity analysis of the band patterns failed to identify characteristic fingerprints associated with the pear cultivars. Both environmentally and biologically based principal-component analyses showed that the microbial communities changed significantly throughout the year depending on temperature and, to a lesser extent, on tree phenology and rainfall. Prominent DGGE bands were excised and sequenced to gain insight into the identities of the predominant bacterial populations. Most DGGE band sequences were related to bacterial phyla, such as Bacteroidetes, Cyanobacteria, Acidobacteria, Proteobacteria, Nitrospirae, and Gemmatimonadetes, previously associated with typical agronomic crop environments

Genetic characterization of the ABO blood group in Neandertals

Background: The high polymorphism rate in the human ABO blood group gene seems to be related to susceptibility to different pathogens. It has been estimated that all genetic variation underlying the human ABO alleles appeared along the human lineage, after the divergence from the chimpanzee lineage. A paleogenetic analysis of the ABO blood group gene in Neandertals allows us to directly test for the presence of the ABO alleles in these extinct humans. Results: We have analysed two male Neandertals that were retrieved under controlled conditions at the El Sidron site in Asturias (Spain) and that appeared to be almost free of modern human DNA contamination. We find a human specific diagnostic deletion for blood group O (O01 haplotype) in both Neandertal individuals. Conclusion: These results suggest that the genetic change responsible for the O blood group in humans predates the human and Neandertal divergence. A potential selective event associated with the emergence of the O allele may have therefore occurred after humans separated from their common ancestor with chimpanzees and before the human-Neandertal population divergence.

CLFP intrinsic constraints-based group management of blended learning situations

When applying a Collaborative Learning Flow Pattern (CLFP) to structure sequences of activities in real contexts, one of the tasks is to organize groups of students according to the constraints imposed by the pattern. Sometimes,unexpected events occurring at runtime force this pre-defined distribution to be changed. In such situations, an adjustment of the group structures to be adapted to the new context is needed. If the collaborative pattern is complex, this group redefinitionmight be difficult and time consuming to be carried out in real time. In this context, technology can help on notifying the teacher which incompatibilitiesbetween the actual context and the constraints imposed by the pattern. This chapter presents a flexible solution for supporting teachers in the group organization profiting from the intrinsic constraints defined by a CLFPs codified in IMS Learning Design. A prototype of a web-based tool for the TAPPS and Jigsaw CLFPs and the preliminary results of a controlled user study are alsopresented as a first step towards flexible technological systems to support grouping tasks in this context.

Why do workers leave unions? - group differences in a Spanish Union Federation

This study analyses the characteristics of members leaving a Spanishunion federation – Catalonia branch of Workers’ Commissions(CCOO-Catalonia), together with their reasons for leaving using avariety of data sources. Our findings indicate that higher union attritionamong members in instable employment (i.e. casual employment andlow seniority). In general, union leavers confirm that their job situationis an important reason for leaving the union. We therefore concludethat efforts made by the union to retain members in vulnerable labormarket positions are important in reducing high rates of union attritionin Spain.

Diagnosi de necessitats socials i educatives de l'aula multilingüe: aproximació des del cas de matemàtiques

El nostre objectiu principal ha estat estudiar el desenvolupament de competències discursives de l’alumnat (d’origen) estranger que contribueixin a entendre i atendre les seves necessitats socials i educatives a l’aula (de matemàtiques) multilingüe. Amb aquesta intenció, hem dut a terme accions científiques a dos nivells: amb professorat i amb estudiants. Quant a la caracterització de la complexitat normativa de l’aula de matemàtiques multilingüe, tal com estava previst: 1) hem exemplificat diverses normes socials i lingüístiques existents en el desenvolupament de pràctiques matemàtiques a l’aula; i 2) hem particularitzat el fenomen de la diversitat de normes socials i lingüístiques en casos de sessions de classe de secundària. Quant a la documentació d'indicadors de progrés en la comprensió de normes socials i lingüístiques de l’aula, i en el desenvolupament de competències discursives d’adequació a aquestes normes, tal com estava previst: 1) hem caracteritzat estratègies d’ensenyament i aprenentatge de normes socials i lingüístiques en situacions d’interacció social en petit i gran grup; i 2) hem construït criteris de seguiment del grau de desenvolupament de competències discursives d’adequació a les normes, tant pel que a professorat com alumnat. Finalment, quant a l'anàlisi de la contribució de les competències discursives a la construcció d’identitats socials, lingüístiques i matemàtiques compartides: 1) hem estudiat els usos que l’estudiant (d’origen) estranger fa de normes escolars vinculades a pràctiques socials, lingüístiques i matemàtiques; i 2) hem examinat la construcció de significats socials, lingüístics i matemàtics compartits en un ampli ventall de processos d’adequació a normes de l’aula orquestrades pel professorat de la nostra mostra.

Gènere i immigració en les narratives visuals de les noies dels països del sud d’Àsia escolaritzades a Catalunya

Aquesta recerca aborda la interpretació de les relacions entre escolarització, immigració i gènere de forma complexa mitjançant la construcció d’una recerca visual narrativa i d’històries de vida amb el grup de noies/dones immigrades procedent dels països del sud d’Àsia que viuen i han estat escolaritzades –totalment o parcialment– a Catalunya. La investigació dóna visibilitat a les trajectòries d’èxit escolar de les noies/dones immigrades al seu pas per l’escola secundària, tot narrant: les seves expectatives i desitjos, els moments i canvis, les identitats i relacions, així com els aprenentatges assolits i les perspectives de futur. La recerca s’ha portat a terme a partir d’observar, entrevistar i conversar amb diversos grups de noies immigrades (principalment de la regió del Panjab de l’Índia i el Pakistan) en 4 centres educatius i 1 entitat, de l’àmbit de Barcelona i la seva àrea metropolitana. La investigació reconstrueix la trajectòria de 20 noies immigrades com a protagonistes. El treball de camp etnogràfic i la construcció de les històries visuals de vida culmina amb l’edició d’un documental audiovisual. De forma resumida, l’anàlisi de les dades realitzada a partir del treball de camp etnogràfic, de les entrevistes en profunditat i les converses en els cinc contextos presentats, s’organitza d’acord amb els següents eixos temàtics: 1. Migracions, espacialització i mobilitat en un context transnacional i local; 2. La construcció de les subjectivitats i del gènere de les adolescents/adultes immigrades; 3. Processos d’escolarització i formació a Catalunya de les noies/dones immigrades; i 4. Visibilitat, visualitat i representació en la recerca.

PhD Students’ Research Group Social Capital in Two Countries: A Clustering Approach with Duocentred Network Measures

The article examines the structure of the collaboration networks of research groups where Slovenian and Spanish PhD students are pursuing their doctorate. The units of analysis are student-supervisor dyads. We use duocentred networks, a novel network structure appropriate for networks which are centred around a dyad. A cluster analysis reveals three typical clusters of research groups. Those which are large and belong to several institutions are labelled under a bridging social capital label. Those which are small, centred in a single institution but have high cohesion are labelled as bonding social capital. Those which are small and with low cohesion are called weak social capital groups. Academic performance of both PhD students and supervisors are highest in bridging groups and lowest in weak groups. Other variables are also found to differ according to the type of research group. At the end, some recommendations regarding academic and research policy are drawn
