Risc i seguretat en el context educatiu: un debat necessari en el marc d'una educació orientada al desenvolupament de la ciutadania

En aquest article se profunditza en torna a les repercusions dels nous escenaris teòrics relacionats amb el desenvolupament del concepte de risc en la segona modernitat. Les tradicions d'anàlisi de la violència escolar o de la gestió positiva del conflicte, han constituït-del fet encara avui dia constitueixen- referents importants per a l'anàlisi de la seguretat en els centres educatius, però el desenvolupament d'un nou concepte de seguretat humana sorgit a partir dels Programes de les Nacions Unides pel Desenvolupament (PNUD) proporciona un marc de reflexió més ampli. Partint d'aquesta perspectiva, se pretèn operativitzar un model que permeti comprendre com es construeix la percepció de risc en el context escolar.

The meaning of marriage for men during the transition to fatherhood : the Swiss context

In Europe, Switzerland presents an unusual pattern of marriage with a very high proportion of couples who begin to cohabit without being married, but with a very low proportion of nonmarital births. A lot of couples marry before the conception of the child or during the pregnancy. In this article we focus on the point of view of men vis-agrave-vis the marriage and its meanings. Qualitative investigations show that men strongly desire marriage for several reasons, from their desire to participate in child rearing to the fear of having their paternity denied by Swiss institutions

The influence of work context on demand for master's studies: a comparative analysisi between Brasil and Spain

The communication presents the results of an investigation of exploratory and comparative character which objective is to analyze the influence of the actual labour situation into the demand of official master studies in the field of education. The study has been developed in two countries with a very different labour situation: Brasil, country of economic expansion and Spain, in recession due to the actual economic crisis. In that sense, the study provides data for deep thinking about the influence of the constriction or expansion of employment on the behaviour and demand of the students who access master studies and on how the previous formative and labour trajectory affects their expectations, demands and future projects. The working methodology is qualitative and the strategy for data collection the “focus group”. As a first approach, two groups of discussion have been formed with master students. A first one with students from Universidad de Barcelona- España and another one with members of Universidade do Vale do Itajaí- Brasil. Then, we constituted a mixed group of discussion in order to analyze differences and similarities.

INdividual SUrveys in RAllies (INSURA), A new tool for exploring transnational activism?

Prior the middle of the 90', interviewing participants in protest events was quiet rare. INdividual SUrveys in RAllies (INSURA) did enter the social researcher's usual toolkit only in the following decade after Favre, Fillieule and Mayer (1997) conducted such a survey with as a primary ambition to build a solid methodological framework that could be subsequently applied by other researchers. After some years of intensive use of INSURA, one is entitled to wonder whether that technique has fulfilled social researchers' hopes or not. In that paper, results of a collective work on alter-global rallies in Evian and Saint- Denis are used to answer three interrelated questions. Firstly, some basic methodological questions about how to collect data on crowds are adressed. What are the specific constraints of interviewing people at the very moment they are "expressing" a political opinion? What specific constraints result from the morphology of the covered events, that is to say, how to build a valid sampling frame? The authors then turn to a more general point about the questions that can be solved, or not, using that technique. Secondly it is the strenghts and weaknesses of INSURA in exploring the transnational dimension of alter global protests that is adressed. The authors show that INSURA is certainly well suited to explore the demographics of alter-global events, as well as relational networks of individuals and multiple belongings. On the contrary, it is assumed that organization networks and movement's boundaries are far more difficult to explore through that method, a fact that seriously limits international cross comparisons of events and movements based on that tool.

El professorat d'Educació Física a l'escola multicultural. Percepcions del context i necessitats de formació

El present article se centra en la situació del professorat d'Educació Física i les seves necessitats formatives per actuar adequadament en entorns d'escola multicultural. Amb aquesta finalitat es presenta la importància de l'educació física com a agent socialitzador per a l'alumnat immigrant, les diferents tendències de les investigacions específiques sobre formació del professorat d'Educació Física en temes d'immigració, i les dades obtingudes a través d'una investigació específica realitzada amb una mostra de 230 centres escolars de tot Catalunya. Com a aspectes més remarcables, cal assenyalar que encara que l'educació física i l'esport poden representar un espai de trobada molt valuós per a la interculturalitat, és important no deixar de banda una educació orientada cap a la convivència, i que la formació del professorat sigui coherent amb les necessitats reals que s'observen en i des dels centres escolars.

Mètode Llisterri : Cada alumne és un món i cada món té el seu propi context

L'objecte d'aquest projecte es troba en l'aplicació d'un mètode que, atenent a les característiques individuals dels alumnes de la forma el més acurada possible i des d'una perspectiva constructivista, permeti establir uns horaris d'estudi personalitzats que mostrin a l'estudiant el temps que ha de dedicar a cada assignatura, el seu ordre i la seva durada per sessió.

Molecular Analysis of the PTEN Gene in a Choroidal Schwannoma in the Context of a Hamartomatous Syndrome

Purpose: To investigate the molecular involvement of PTEN, a tumor suppressor gene, in a case of cellular pigmented choroidal Schwannoma in a patient with hamartomatous syndrome due to heterozygous PTEN germline mutation. Methods: Histopathological, immunohistochemical, and electron microscopy analyses were performed by standard procedures. Paraffin-embedded samples of normal and tumor eye tissues were collected and DNA was extracted. A 145 bp region flanking the heterozygous c.406T>C mutation in exon 5 of PTEN was amplified by PCR and sequenced. To evaluate the allelic status of PTEN in the tumor sample, we cloned different PCR products in E. coli using a TA cloning procedure. Results: Histopathology demonstrated a posterior choroidal mass measuring 1.3 x 1.6 x 1.4 cm. The tumor was composed by fascicles of spindle cells with wavy cytoplasm. No Verrocay bodies could be identified. Scattered histiocytes with clear cytoplasm were present. By immunohistochemistry, the cells were expressing S100 and focally Melan A proteins. Pericellular type IV collagen could be demonstrated. Interlacing cytoplasmic processes covered by thick basement membrane could be found by electron microscopy as well as few premelanosomes. Moderate PTEN expression by immunohistochemistry was identified in some cells. As expected, the germline mutation could be detected by DNA sequencing in both the paraffin-embedded normal and tumor eye tissues. Analysis of 33 E. coli colonies bearing clones from the tumor eye tissue DNA surprisingly revealed that most of them contained the PTEN wild-type allele (29 vs. 4, Fisher's test p-value = 0.002). Conclusions: This is the first reported case of choroidal cellular Schwannoma arising in the context of a PTEN hamartomatous syndrome. Allelic analysis of PTEN in the tumor suggests a statistically-significant partial loss of heterozygozity in favor of the wild-type allele. Our findings are in clear contrast with what is usually observed in cancer tissues, for which mutated alleles of tumor suppressor genes are usually brought to homozygosity. Similar results were previously reported in human non-Hodgkin's lymphomas, displaying an overexpression of the wild-type form of the tumor suppressor gene p53. We are in the process of investigating additional DNA derived from other fresh and paraffin-embedded tissues from the patient, in order to gain insights on the molecular bases of PTEN involvement in this rare choroidal Schwannoma.
