The cuticular hydrocarbons of the Triatoma sordida subcomplex (Hemiptera: Reduviidae: Triatominae) were ana-lysed by gas chromatography and their structures identified by mass spectrometry. They comprised mostly n-alkanes and methyl-branched alkanes with one-four methyl substitutions. n-alkanes consisted of a homologous series from C21-C33 and represented 33-45% of the hydrocarbon fraction; n-C29 was the major component. Methyl-branched alkanes showed alkyl chains from C24-C43. High molecular weight dimethyl and trimethylalkanes (from C35-C39) represented most of the methyl-branched fraction. A few tetramethylalkanes were also detected, comprising mostly even-numbered chains. Several components such as odd-numbered 3-methylalkanes, dimethylalkanes and trimethylalkanes of C37 and C39 showed patterns of variation that allowed the differentiation of the species and populations studied. Triatoma guasayana and Triatoma patagonica showed the most distinct hydrocarbon patterns within the subcomplex. The T. sordida populations from Brazil and Argentina showed significantly different hydrocarbon profiles that posed concerns regarding the homogeneity of the species. Triatoma garciabesi had a more complex hydrocarbon pattern, but it shared some similarity with T. sordida. The quantitative and qualitative variations in the cuticular hydrocarbons may help to elucidate the relationships between species and populations of this insect group.

In this paper we present a Linguistic Meta-Model (LMM) allowing a semiotic-cognitive representation of knowledge. LMM is freely available and integrates the schemata of linguistic knowledge resources, such as WordNet and FrameNet, as well as foundational ontologies, such as DOLCE and its extensions. In addition, LMM is able to deal with multilinguality and to represent individuals and facts in an open domain perspective.

Background: The exploratory study is part of an evaluation of the pre-graduate teaching of communication skills (Lausanne Medical School). It is based on the data of a project highlighting the impact of individualized vs. group training for medicine students in breaking bad news to simulated patients who are diagnosed with cancer. The analysis of the video-taped interviews of the students (N=63) with the RIAS has shown a current usage of utterances such as I don't know if -you have any plans for the future / you have already heard about chemotherapy / ... or I don't know how -you are feeling today after this surgery / you like that all this stuff takes place / ...Aim: The present study questions the specificity of these assertive utterances used as questions (indirect), the specificity of their content, and their intentionality - specific vs. exploratory.Methods: The mentioned utterances are qualitatively analyzed (content analysis, intentionality analysis, etc).Results: 26 students (41%) used 1 to 6 times I don't know utterances during the interviews that contain 53 of such utterances in total. In contrast, they are atypical in an oncologist sample who conducted similar interviews (N=31; 4 oncologist used them 1 to 2 times). In more than half of the cases (29/53), simulated patients interpret I don't know questions as giving them a space to speak (open responses). Conclusions: The atypicality of the I don't know utterances in the oncologist sample may have linguistic explanations in terms of generational marker, but the specificity of the content suggests psychological explanations in terms of defense mechanism as well (marker of "toning down" or insecurity as regards the discussed topic).Keywords: Breaking bad news, communication skills, oncology, pre-graduate medical education, indirect questioning

This research investigates differences in the stereotype content of immigrant groups between linguistic regions. We expected that immigrant groups who speak the local language of a specific linguistic region would be perceived as more competitive within this region than in another linguistic region. Further, we expected these differences would underlie regional differences in stereotype content, albeit only for the warmth dimension. Predictions were tested in the two largest linguistic regions of Switzerland. As expected, in the German-speaking region, locals perceived German immigrants as more competitive and thus as less warm, whereas in the French-speaking region, locals perceived French immigrants as more competitive and, consequently, as less warm. So, paradoxically, immigrants with strong integration potential are particularly disliked because they are regarded as direct competitors.

Sponsored by the Health Administrations of nine cantons, this study was conducted by the University Institute of Social and Preventive Medicine in Lausanne in order to assess how DRGs could be used within the Swiss context. A data base mainly provided by the Swiss VESKA statistics was used. The first step provided the transformation of Swiss diagnostic and intervention codes into US codes, allowing direct use of the Yale Grouper for DRG. The second step showed that the overall performance of DRG in terms of variability reduction of the length of stay was similar to the one observed in US; there are, however, problems when the homogeneity of medicotechnical procedures for DRG is considered. The third steps showed how DRG could be used as an account unit in hospital, and how costs per DRG could be estimated. Other examples of applications of DRG were examined, for example comparison of Casemix or length of stay between hospitals.

Aquest treball té com a objectiu analitzar el multilingüisme a la Unió europea des d’una perspectiva interdisciplinària entre traducció i dret de la Unió europea. Aquest article estudia la Unió com a un sistema multilingüe, amb especial èmfasi en les raons jurídiques i polítiques darrera l’actual règim lingüístic. També s’intentarà examinar els efectes que la diversitat lingüística té en la interpretació de la legislació europea. Hi han vint i tres llengües oficials i els textos publicats en les diferents llengües son igualment autèntics (Article 55 TFUE). Però les regles poden tenir la mateixa implicació jurídica en mes d’una llengua?

Mouse interleukin 3 (IL-3) cDNA was cloned into a plasmid construction, allowing the synthesis of very high quantities of IL-3 in Escherichia coli. The recombinant (r) IL-3, purified to homogeneity, was active in vitro on the proliferation and differentiation of various hematopoietic progenitor cells at 1 pM. To maintain detectable blood levels of IL-3, osmotic pumps containing rIL-3 or control solutions were placed under the skin of normal and irradiated C3H/HeJ and (BALB X B10) F1 mice. The effect of IL-3 on hematopoietic progenitor cell numbers in spleen and bone marrow was evaluated 3 and 7 days later by using an in vitro clonal assay. The results demonstrated the following: (i) Doses of IL-3 infused at the rate of 2.5-5 ng per g of body weight per hr were sufficient to increase the numbers of hematopoietic progenitors in normal mice by at least 2-fold within 3 days. (ii) In mice with progenitor cell levels depressed by sublethal irradiation, 7-day treatment with IL-3 resulted in a 10-fold increase to near normal levels. (iii) The erythroid and myeloid lineages appeared to be enhanced to the same extent. (iv) Enhancement of hematopoiesis occurred primarily in spleen, but hematopoietic foci were also evident in the liver; in contrast, total cell and progenitor cell numbers were decreased in the bone marrow.

PURPOSE: Early assessment of radiotherapy (RT) quality in the ongoing EORTC trial comparing primary temozolomide versus RT in low-grade gliomas. MATERIALS AND METHODS: RT plans provided for dummy cases were evaluated and compared against expert plans. We analysed: (1) tumour and organs-at-risk delineation, (2) geometric and dosimetric characteristics, (3) planning parameters, compliance with dose prescription and Dmax for OAR (4) indices: RTOG conformity index (CI), coverage factor (CF), tissue protection factor (PF); conformity number (CN = PF x CF); dose homogeneity in PTV (U). RESULTS: Forty-one RT plans were evaluated. Only two (5%) centres were requested to repeat CTV-PTV delineations. Three (7%) plans had a significant under-dosage and dose homogeneity in one deviated > 10%. Dose distribution was good with mean values of 1.5, 1, 0.68, and 0.68 (ideal values = 1) for CI, CF, PF, and CN, respectively. CI and CN strongly correlated with PF and they correlated with PTV. Planning with more beams seems to increase PTV(Dmin), improving CF. U correlated with PTV(Dmax). CONCLUSION: Preliminary results of the dummy run procedure indicate that most centres conformed to protocol requirements. To quantify plan quality we recommend systematic calculation of U and either CI or CN, both of which measure the amount of irradiated normal brain tissue.

BACKGROUND Skin patch test is the gold standard method in diagnosing contact allergy. Although used for more than 100 years, the patch test procedure is performed with variability around the world. A number of factors can influence the test results, namely the quality of reagents used, the timing of the application, the patch test series (allergens/haptens) that have been used for testing, the appropriate interpretation of the skin reactions or the evaluation of the patient's benefit. METHODS We performed an Internet -based survey with 38 questions covering the educational background of respondents, patch test methods and interpretation. The questionnaire was distributed among all representatives of national member societies of the World Allergy Organization (WAO), and the WAO Junior Members Group. RESULTS One hundred sixty-nine completed surveys were received from 47 countries. The majority of participants had more than 5 years of clinical practice (61 %) and routinely carried out patch tests (70 %). Both allergists and dermatologists were responsible for carrying out the patch tests. We could observe the use of many different guidelines regardless the geographical distribution. The use of home-made preparations was indicated by 47 % of participants and 73 % of the respondents performed 2 or 3 readings. Most of the responders indicated having patients with adverse reactions, including erythroderma (12 %); however, only 30 % of members completed a consent form before conducting the patch test. DISCUSSION The heterogeneity of patch test practices may be influenced by the level of awareness of clinical guidelines, different training backgrounds, accessibility to various types of devices, the patch test series (allergens/haptens) used for testing, type of clinical practice (public or private practice, clinical or research-based institution), infrastructure availability, financial/commercial implications and regulations among others. CONCLUSION There is a lack of a worldwide homogeneity of patch test procedures, and this raises concerns about the need for standardization and harmonization of this important diagnostic procedure.

El treball en primer lloc presenta una breu introducció del moviment esperantista, explicitant els vincles entre pacifisme i esperantisme, particularment en el cas català. En segon lloc, i a partir d’una enquesta a aquest subconjunt del moviment per la pau, l’estudi, d’una banda, compara les característiques d’aquest col·lectiu amb les de la societat catalana i amb la d’esperantistes d’altres països. D’altra banda, analitza el grup mateix i l’eventual evolució personal dels seus membres. L’estudi no sobreentén, com en enquestes anteriors en altres països, el concepte d’«esperantista» com el fet de ser membre d’una associació esperantista, sinó que estudia quina concepció en tenen els mateixos membres del col·lectiu i persones pròximes. Els resultats mostren algunes diferències notables entre els esperantistes catalans i la resta de la població catalana, particularment en relació amb el nivell d’estudis, les opinions polítiques i el lleure. Per altra banda, confirma els resultats obtinguts amb esperantistes d’altres països, malgrat algunes diferències sensibles, que potser podrien explicar-se per la minorització nacional i lingüística dels catalans.

This paper presents the analysis of a website created in 2011 by the Federal Office of Public Health (FOPH) to support an information campaign about the organ donation. Observing how a Swiss institution publicly communicates about an issue belonging to the private sphere, this paper describes how the semiotic and discursive resources are mobilised to meet specific goals: promoting discussion and decision about the organ donation while maintaining complete neutrality about the topic. In order to do this, we first discuss the issue of publicising organ donation in Switzerland; then we conduct a detailed analysis of the website to understand the role of the linguistic forms and structures in the communication strategy of the FOPH. This strategy relies on the representation of a public sphere in which ordinary people express conflicting positions about organ donation.

The authors report three children who suffered temporary oromotor or speech disturbances as focal epileptic manifestations within the frame of benign partial epilepsy of childhood with rolandic spikes and review similar cases described in the literature. The deficit can occur as an initial symptom of the disorder without visible epileptic seizures and interferes in a variable way with simple voluntary oromotor functions or complex movements including speech production, depending on the exact location and spread of the discharging epileptic focus around the perisylvian region. The most severe deficit produces the anterior operculum syndrome. More subtle non-linguistic deficits such as intermittent drooling, oromotor apraxia or dysfluency, as well as linguistic ones involving phonologic production, can occur. The rapidity of onset, progression and recovery of the deficit is very variable as well as its duration and presumably reflects the degree of epileptic activity. In some cases, rapid improvement with antiepileptic medication occurs and coincidence between the paroxysmal EEG activity (which is usually bilateral) and the functional deficit is seen. The clinical and EEG profile of the seizures disorder and the dynamic of the deficit in these cases bear a strong resemblance to what is seen in the acquired epilepsy-aphasia syndrome (Landau and Kleffner). The variations in clinical symptoms appear more related to the main site, local extension and bilaterality of the epileptic foci rather than a basic difference in physiopathology.

Deduction allows us to draw consequences from previous knowledge. Deductive reasoning can be applied to several types of problem, for example, conditional, syllogistic, and relational. It has been assumed that the same cognitive operations underlie solutions to them all; however, this hypothesis remains to be tested empirically. We used event-related fMRI, in the same group of subjects, to compare reasoning-related activity associated with conditional and syllogistic deductive problems. Furthermore, we assessed reasoning-related activity for the two main stages of deduction, namely encoding of premises and their integration. Encoding syllogistic premises for reasoning was associated with activation of BA 44/45 more than encoding them for literal recall. During integration, left fronto-lateral cortex (BA 44/45, 6) and basal ganglia activated with both conditional and syllogistic reasoning. Besides that, integration of syllogistic problems additionally was associated with activation of left parietal (BA 7) and left ventro-lateral frontal cortex (BA 47). This difference suggests a dissociation between conditional and syllogistic reasoning at the integration stage. Our finding indicates that the integration of conditional and syllogistic reasoning is carried out by means of different, but partly overlapping, sets of anatomical regions and by inference, cognitive processes. The involvement of BA 44/45 during both encoding (syllogisms) and premise integration (syllogisms and conditionals) suggests a central role in deductive reasoning for syntactic manipulations and formal/linguistic representations.

Teixint Cultures és un projecte de recerca-acció comunitari que intenta promoure des de I'educació d'adults, I'aprenentatge de la llengua catalana a partir dels recursos Iingüístics que les mares d'origen africà tenen en la seva llengua familiar. El programa atén a mares d'origen immigrat amb fills menors de tres anys no escolaritzats al seu càrrec (la majoria de les quals té altres fills en edat escolar que assisteixen a la tarda a la biblioteca per fer els deures escolars). Tot el projecte esta vehiculat a partir dels contes infantils. De fet, intenta recuperar els contes de tradició oral provinents del continent africà per posteriorment elaborar materials educatius bilingües (en català i en les seves llengües) que es puguin utilitzar com a llibres educatius de consulta, tant per les biblioteques públiques com pels centres educatius. El programa es realitza de forma setmanal, al llarg de dues hores, a la biblioteca pública infantil d'en Massagran de Salt. Les mares expliquen contes i llegendes rellevants de la seva infància en la seva llengua i, a partir de diferents activitats de narració, traducció i dramatització de les històries basades en una metodologia de a dual-language D, elaboren textos escrits i narracions orals en català i en la seva llengua. Posteriorment són les mateixes participants les que editen els contes a I'ordinador i elaboren digitalment un llibre de contes bilingüe. Les sessions s'han registrat en àudio i vídeo i hem estudiat el procés d'implementació del programa i les estratègies multilingües utilitzades per les participants, els educadors i voluntaris. Els resultats evidencien el progrés de les dones en I'aprenentatge del català, la modificació de les seves actituds lingüístiques i de la seva autoimatge, així com I ‘impacte positiu del programa a la comunitat pel que fa al reconeixement dels recursos lingüístics i culturals de les minories ètniques.

From an interdisciplinary perspective, the present investigation undertaken by the GREILI-UPF research group has expanded a previous study aiming at explaining how young secondary school students of Latin American and Chinese origin in Catalonia construct their linguistic and cultural identity. Here we analyze the relationship between these youngsters and their social environment in order to determine how these relationships and the socialization process that derives from them influence language attitudes and practices. We focus on two spaces of socialization: (1) the school, where youngsters from diverse cultural and linguistic backgrounds coexist and interact, and (2) the neighborhood, a geographic and symbolic space where social identity is constructed and, consequently, where young newcomers construct their perceptions regarding the host society, including its linguistic reality. We have collected several sets of data in three public secondary schools and three neighborhoods from Barcelona’s metropolitan area with a high index of immigrant population: (1) interviews with secondary school students, (2) interviews with teachers, (3) social discourses in newspapers that consolidate the social image of the neighborhood, (4) narratives from immigrant families in relation to their neighborhood, (5) participant observation in schools, and (5) observation in the neighborhood. The results of the thematic and, when appropriate, discursive analysis of the data allow us to reach conclusions regarding: (a) the social image of the neighborhoods, (b) the socialization of young newcomers in the schools and the neighborhoods, (c) the identity games, and (d) the language and cultural practices and attitudes of young people, in relation to their countries and languages of origin as well as the school and the neighborhood investigated.
