O outro lado da guerra colonial. Perspetiva salutogénica de inclusão

O projeto de investigação-intervenção aqui apresentado, denominado O outro lado da guerra colonial. Memórias na primeira pessoa, fundamenta-se nas conceções da Educação e Aprendizagem ao Longo da Vida, sendo direcionado para a área da Educação para a Saúde. Remete-nos para uma perspetiva salutogénica de saúde, de acordo com A. Antonovsky. Ao nível metodológico incorre no Paradigma da Complexidade. Utilizam-se métodos diversificados consoante os casos concretos, nomeadamente o método narrativo. Neste estudo, destacam-se as narrativas como forma de ação/intervenção junto de 11 participantes, veteranos da guerra colonial portuguesa. As narrativas foram determinantes, constituindo o modo de construção, de atribuição de significado e partilha de memórias pessoais subjetivas, que revelam perspetivas diversificadas e modos únicos de interpretar e compreender um evento histórico importante. A partir dos dados recolhidos foram-se descobrindo os Recursos Gerais de Resistência e foi-se conhecendo/reconhecendo o Sentido Interno de Coerência de cada participante, construindo-se planos de ação pessoais. Os participantes compreenderam o papel que desempenham na promoção da sua própria saúde e a importância que esta compreensão representa nas suas vidas. Neste sentido, este projeto de investigação/intervenção permitiu-nos analisar, comprender e valorizar as experiências de vida de caráter transformador que culminaram em momentos de grande aprendizagem pessoal; forneceu-nos elementos importantes para o estudo qualitativo dos veteranos de guerra, revelando dados significativos acerca das vivências da guerra colonial e acerca do modo como essas vivências influenciaram a vida dos participantes até aos días de hoje. A utilização de métodos exclusivamente qualitativos tornou-se essencial neste projeto de investigação/intervenção. Através da subjetividade discursiva tivemos acesso a mundos de significado próprios que proporcionaram um ambiente investigativo de proximidade e intimidade. Conclui-se que este estudo foi revelador porque permitiu a recolha de dados que contribuíram para a valorização das memórias pessoais mas também para a construção de futuros planos de ação e de investigação.

A regulação do lobo anterior da hypophyse por um hormonio testicular, especialmente sob o ponto de vista morphologico

The authors summarize the results of former works, based on the technics of parabiosis. After parabiotic union of two infantile rats, normal + castrate, the normal fellow enters into precocious puberty in about 7 days (Kallas). In the case of pairs: castrated male + normal female, the implants of testicles, or injection of maceration or aqueous extracts of testis in the castrated fellow, prevents the induction of early puberty in the normal female. In the case: castrated female + normal female, no inhibiting effect is provoked by that treatment. There is therefore a testicular hormone that regulates the hypophysis. After castration, this gland manifests a hyper-function and shows histological alterations, the chief character of these being the appearing in the anterior lobe, of the so-called castration cells, probably originated from basophile cells. Implants or injections of testis material prevent those alterations. This is a useful test; the effect is controlled by estimating the castration cells in the microscopic field. The testicular hormone that regulates the anterior lobe is probably another one, quite different from that which regulates the accessory genitalia. On account of the facts and experiments, it may be assumed that this new hormone is elaborated by the germinal epithelium of the testicles.

Disseny i proposta d' implementació d'un model formatiu per a la iniciació professional i el mentoratge del professorat de secundària

En estudis anteriors al que ara us proposem i en diferents articles realitzats pels components d’aquest grup de recerca s’ha constatat que el professorat que ha d’atendre grups d’alumnes amb adaptacions curriculars, programes d’iniciació professional, alumnes amb difícil inclusió acadèmica i escolar que aquests docents haurien de rebre una formació psicopedagògica per adequar-se al trets característics dels alumnes i per aplicar una metodologia que desperti en els alumnes la il•lusió per seguir formant-se i les estratègies organitzatives i de planificació per fer un ensenyament de qualitat. El professorat ha d’adquirir una sèrie de competències que li permetin donar resposta a les necessitats dels alumnes. Estudis previs constaten que hi ha una gran necessitat pel que fa a les competències personals i participatives per sobre de les tècniques. Tot i que també és molt important apostar per les metodològiques. Aquesta formació l'haurà de rebre al llarg de la seva acció docent i està lliga amb el concepte Lifelong learning que es proposa arreu de la Unió Europea con un dret i una obligació per aconseguir la constant adequació a les demandes socials i a les necessitats personals, així com assolir la progressió professional i l’accés a noves etapes educatives:No hi ha dubte que una professió com la docent que requereix un domini competencial tan exigent desvetlla la curiositat per iniciar recerques i la necessitat d’esmerçar esforços per facilitar que tingui èxit la inserció dels nous professors i professores en l’entorn socioeducatiu durant el període llindar. Cal saber què passa, què ocupa i què preocupa a Europa en relació al professorat i a la seva formació, sobretot que cal desenvolupar en el període previ i com es facilita la transició des d’aquesta formació inicial per assolir una ràpida i eficaç inserció a la professió docent.   

Un problema d'excés: l'eutrofització

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. L’objectiu del treball era el de comprovar si era possible provocar un procés d'eutrofització en unes peixeres, com a simulació del procés que es dóna de forma natural en alguns llacs i basses del nostre país. Mantenint una peixera de control, en les altres dues hi provocàvem un excés de nutrients abocant fertilitzant sintètic en diferents concentracions per tal de comprovar les diferències causades per aquest procés de contaminació ambiental. Una vegada fet l'experiment, tot i que no s’ha aconseguit un alt grau d’eutrofització i per tant, no s’ha pogut demostrar moltes de les conseqüències d’aquest procés, sí que s’ha aconseguit dur a terme una contaminació i s’ha pogut observar com evoluciona un medi alterat per l’home respecte un ecosistema amb òptimes condicions. Al comparar aquest experiment amb la realitat actual s’observa que tots els canvis que han succeït a petita escala en aquests ecosistemes, en la natura, es produeixen en un major grau i amb unes conseqüències molt més adverses pels organismes.

Référentiels des compétences et des métiers : une approche ontologique

Résumé La mondialisation des marchés, les mutations du contexte économique et enfin l'impact des nouvelles technologies de l'information ont obligé les entreprises à revoir la façon dont elles gèrent leurs capitaux intellectuel (gestion des connaissances) et humain (gestion des compétences). II est communément admis aujourd'hui que ceux-ci jouent un rôle particulièrement stratégique dans l'organisation. L'entreprise désireuse de se lancer dans une politique gestion de ces capitaux devra faire face à différents problèmes. En effet, afin de gérer ces connaissances et ces compétences, un long processus de capitalisation doit être réalisé. Celui-ci doit passer par différentes étapes comme l'identification, l'extraction et la représentation des connaissances et des compétences. Pour cela, il existe différentes méthodes de gestion des connaissances et des compétences comme MASK, CommonKADS, KOD... Malheureusement, ces différentes méthodes sont très lourdes à mettre en oeuvre, et se cantonnent à certains types de connaissances et sont, par conséquent, plus limitées dans les fonctionnalités qu'elles peuvent offrir. Enfin, la gestion des compétences et la gestion des connaissances sont deux domaines dissociés alors qu'il serait intéressant d'unifier ces deux approches en une seule. En effet, les compétences sont très proches des connaissances comme le souligne la définition de la compétence qui suit : « un ensemble de connaissances en action dans un contexte donné ». Par conséquent, nous avons choisi d'appuyer notre proposition sur le concept de compétence. En effet, la compétence est parmi les connaissances de l'entreprise l'une des plus cruciales, en particulier pour éviter la perte de savoir-faire ou pour pouvoir prévenir les besoins futurs de l'entreprise, car derrière les compétences des collaborateurs, se trouve l'efficacité de l'organisation. De plus, il est possible de décrire grâce à la compétence de nombreux autres concepts de l'organisation, comme les métiers, les missions, les projets, les formations... Malheureusement, il n'existe pas réellement de consensus sur la définition de la compétence. D'ailleurs, les différentes définitions existantes, même si elles sont pleinement satisfaisantes pour les experts, ne permettent pas de réaliser un système opérationnel. Dans notre approche; nous abordons la gestion des compétences à l'aide d'une méthode de gestion des connaissances. En effet, de par leur nature même, connaissance et compétence sont intimement liées et donc une telle méthode est parfaitement adaptée à la gestion des compétences. Afin de pouvoir exploiter ces connaissances et ces compétences nous avons dû, dans un premier temps, définir les concepts organisationnels de façon claire et computationnelle. Sur cette base, nous proposons une méthodologie de construction des différents référentiels d'entreprise (référentiel de compétences, des missions, des métiers...). Pour modéliser ces différents référentiels, nous avons choisi l'ontologie, car elle permet d'obtenir des définitions cohérentes et consensuelles aux concepts tout en supportant les diversités langagières. Ensuite, nous cartographions les connaissances de l'entreprise (formations, missions, métiers...) sur ces différentes ontologies afin de pouvoir les exploiter et les diffuser. Notre approche de la gestion des connaissances et de la gestion des compétences a permis la réalisation d'un outil offrant de nombreuses fonctionnalités comme la gestion des aires de mobilités, l'analyse stratégique, les annuaires ou encore la gestion des CV. Abstract The globalization of markets, the easing of economical regulation and finally the impact of new information and communication technologies have obliged firms to re-examine the way they manage their knowledge capital (knowledge management) and their human capital (competence management). It is commonly admitted that knowledge plays a slightly strategical role in the organization. The firms who want to establish one politic of management of these capitals will have to face with different problems. To manage that knowledge, a long process of capitalization must be done. That one has different steps like identification, extraction and representation of knowledge and competences. There are some different methods of knowledge management like MASK, CommonKADS or KOD. Unfortunately, those methods are very difficult to implement and are using only some types of knowledge and are consequently more limited in the functionalities they can offer. Knowledge management and competence management are two different domain where it could be interesting to unify those to one. Indeed, competence is very close than knowledge as underline this definition: "a set of knowledge in action in a specified context". We choose in our approach to rely on the concept of competence. Indeed, the competence is one of crucial knowledge in the company, particularly to avoid the loss of know-how or to prevent future needs. Because behind collaborator's competence, we can find company efficiency. Unfortunately, there is no real consensus on the definition of the concept of competence. Moreover, existing different definitions don't permit to develop an operational system. Among other key concept, we can find jobs, mission, project, and training... Moreover, we approach different problems of the competence management under the angle of the knowledge management. Indeed, knowledge and competence are closely linked. Then, we propose a method to build different company repositories (competence, jobs, projects repositories). To model those different repositories we choose ontology because it permits to obtain coherent and consensual definitions of the concepts with support of linguistics diversities too. This building repositories method coupled with this knowledge and competence management approach permitted the realization of a tool offering functionalities like mobility management, strategical analysis, yellow pages or CV management.

3D visualization software to analyze topological outcomes of topoisomerase reactions.

The action of various DNA topoisomerases frequently results in characteristic changes in DNA topology. Important information for understanding mechanistic details of action of these topoisomerases can be provided by investigating the knot types resulting from topoisomerase action on circular DNA forming a particular knot type. Depending on the topological bias of a given topoisomerase reaction, one observes different subsets of knotted products. To establish the character of topological bias, one needs to be aware of all possible topological outcomes of intersegmental passages occurring within a given knot type. However, it is not trivial to systematically enumerate topological outcomes of strand passage from a given knot type. We present here a 3D visualization software (TopoICE-X in KnotPlot) that incorporates topological analysis methods in order to visualize, for example, knots that can be obtained from a given knot by one intersegmental passage. The software has several other options for the topological analysis of mechanisms of action of various topoisomerases.

Sistema didàctic per millorar l'aprenetatge de la representació del espai arquitectònic amb ajuts "on line"

El projecte ha tingut com a finalitat cobrir un buit en la formació dels estudiants pel que respecta a les seves limitacions en l’aprenentatge de les diferents estratègies i metodologies de treball. Aquest buit ens ha fet pensar en l’elaboració d’un sistema didàctic que possibiliti una comunicació fluida amb l’alumne i que pugui anar més enllà de l’àmbit específic de les aules. Es per això que la nostra proposta té com a referent un aprofitament més racional del temps de treball de l’estudiant. Per tal d’arribar a aquesta finalitat ens hem plantejat un grup d’objectius concrets ordenats segons els dos nivells d’assoliment següents: Nivell 1: - Definir un material didàctic que pugui transmetre de la manera més objectiva possible les eines necessàries per tal que l’alumne resolgui un conjunt de problemes concrets. - Proporcionar a l’estudiant un procediment didàctic basat en un grup de tasques amb un material de suport on ha de posar a prova l’aplicabilitat dels conceptes donats a les classes teòriques. - Partir d’un sistema que permeti a l’alumne tenir una referència constant de recolzament teòric fora de les aules quan està resolent les pràctiques assignades en el curs. - Definir unes característiques funcionals del material utilitzat en l’activitat pràctica de tal manera que sigui un instrument efectiu per al control del propi estudiant sobre el seu procés d’avaluació. Nivell 2: - Fer servir una metodologia d’activitats pràctiques on es puguin accentuar les capacitats de resposta creativa individual de l’estudiant. - Plantejar l’intercanvi d’experiències i propostes d’estratègies per a la resolució dels temes pràctics mitjançant sessions de seminaris prèvies a les pràctiques. - Promoure unes relacions transversals amb altres àrees de coneixement de tal manera que l’alumne pugui vincular la seva resposta a les activitats pràctiques proposades per altres assignatures, amb els coneixements adquirits a la nostra assignatura.

Cryptosporidium sp. in children suffering from acute diarrhea at Uberlândia City, State of Minas Gerais, Brazil

This study's objective was to search for Cryptosporidium sp. in diarrheic feces from children aged zero to 12 years and cared for at medical units within Universidade Federal de Uberlândia or at a private practice in Uberlândia, State of Minas Gerais, Brazil, from September 1992 to August 1993. Three fecal samples preserved in 10% formalin, were collected from 94 children. Oocyst concentration was performed through Ritchie's (modified) method and staining of fecal smears for each sample (total of 1128 slides) was done by the "Safranin/Methylene Blue" and the "Kinyoun (modified)" techniques. The Hoffmann, Pons & Janer method was also employed to look for other enteroparasites. From 94 children, 4.26% excreted fecal Cryptosporidium oocysts. The infection seemed to vary according to age: 5.08% of patients aged zero to two years old; 33.33% of those aging eight to ten years (P>0.05). Cryptosporidium appeared in November, December and March, during the rainy season. 20.21% of the children harbored at least one enteroparasite different from Cryptosporidium, mainly Giardia intestinalis (12.77%). From Cryptosporidium infected patients, two had only this kind, another harbored Giardia intestinalis; the last one hosted Strongyloides stercoralis.

Behavior of Biomphalaria glabrata Say, 1818 (Gastropoda: Planorbidae): I. Morphophysiology of the Mantle Cavity

Using longitudinal and transverse anatomical sections, we observed that the three cristae of the mantle of Biomphalaria glabrata (renal, rectal and dorsolateral cristae) divide the mantle cavity into three chambers which we designated air or pulmonary chamber, water inflow chamber and water outflow chamber. Using videotape filming, we observed the inflow and outflow of air and water into and from the mantle cavity and we related their probable functions such as flotation, oxygen reservoir and transport, excreta circulation and elimination, water skeleton, and modification of specific weight. To determine whether the air bubble may function as a physical gill in this species we submitted three groups of snails to different systems in which water contained the same level of dissolved oxygen whereas the gas phases were atmospheric air, pure nitrogen or pure oxygen. We observed the following parameters: time of permanence on the surface, time of immersion, and frequency at which the snails reached the surface. These results did not demonstrate a physical gill function; morphological analysis of the mantle cavity indicates this possibility

On the automatic application of inequality indexes in the analysis of the international distribution of environmental indicators

In recent years traditional inequality measures have been used to quite a considerable extent to examine the international distribution of environmental indicators. One of its main characteristics is that each one assigns different weights to the changes that occur in the different sections of the variable distribution and, consequently, the results they yield can potentially be very different. Hence, we suggest the appropriateness of using a range of well-recommended measures to achieve more robust results. We also provide an empirical test for the comparative behaviour of several suitable inequality measures and environmental indicators. Our findings support the hypothesis that in some cases there are differences among measures in both the sign of the evolution and its size. JEL codes: D39; Q43; Q56.

Antigen-induced pleural eosinophilia is suppressed in diabetic rats: role of corticosteroid hormones

Previous studies have evidenced for the existence of interactive regulatory mechanisms between insulin and steroid hormones in different systems. In this study, we have investigated whether endogenous corticosteroids could be implicated in the hyporeactivity to antigen challenge observed in sensitized diabetic rats. Alloxinated rats showed a long-lasting increase in the blood glucose levels and a reduction in the number of pleural mast cells at 48 and 72 hr, but not at 24 hr after alloxan administration. In parallel, they also showed a significant elevation in the plasma levels of corticosterone together with an increase in the adrenal/body weight ratio. Antigen-evoked eosinophil accumulation appeared significantly reduced in rats pretreated with dexamethasone as well as in those rendered diabetic 72 hr after alloxan. In the same way, naive animals treated with dexamethasone also responded with a significant decrease in the number of pleural mast cells. Interestingly, when sensitized diabetic rats were pretreated with the steroid antagonist RU 38486 a reversion of the reduction in the allergen-induced eosinophil accumulation was noted. We conclude that the down-regulation of the allergic inflammatory response in diabetic rats is close-related to reduction in mast cell numbers and over expression of endogenous corticosteroids.

BAW notch filter for WiMAX applications

Als darrers anys la necessitat de connectar-se a internet des de qualsevol lloc s’ha incrementat exponencialment sobretot de manera inalàmbrica. Degut al finit espectre radioelèctric es tendeix a aprofitar totes les franges freqüencials d’aquest convivint diferents sistemes en franges properes podent induir-se interferències mútuament. Per evitar aquestes interferències es requereix de filtres a tots els dispositius els quals aïllin un sistema del adjacent. En aquest projecte es dóna una solució al cas concret de la convivència entre els sistemes Wi-Fi y WiMAX eliminant la banda Wi-Fi interferent en sistemes WiMAX. Aquesta solució consisteix en el disseny d’un filtre banda eliminada d’ordre 3 implementat mitjançant tecnologia BAW a partir de l’estructura y especificacions d’un filtre comercial. A més també es fa un petit estudi per veure si seria interessant una millora en els processos de fabricació del filtre per part del fabricant.

Women speaking across the Border: The impact of the Border and the conflict on women's health and roles

This research was commissioned by Derry Well Woman and carried out on its behalf by the Institute of Public Health in Ireland in association with the Institute for Conflict Research and Rethink.The research had two distinct aims:- to improve understanding of the impact of the border and of the conflict on both sidesof the border on women’s health- to improve understanding of women’s roles, particularly as they impact on mental health, in post conflict society.- The research was conducted with a view to its recommendations being used to inform the work of the Cross Border Women’  Health Network as well as other cross border health forums or organisations responsible for service planning and delivery.- The findings of this research are based on a series of 31 in-depth interviews and one focus group with women both north and south of the border and on one focus group and six interviews with women who were specifically consulted as service providers.
