Perfeccionamiento de las metodologías docentes en la enseñanza de la construcción mixta en grado y postgrado en la Universidad Politécnica de Cataluña (UPC) y la Universidad de Camaguey (UC)

Estudio elaborado a partir de una estancia en la Universitat Polictecnica de Cataluña entre marzo i junio del 2007.El proyecto tiene como objetivo general el perfeccionamiento de las metodologías docentes en la enseñanza de la construcción mixta en grado y postgrado en la Universidad Politécnica de Cataluña (UPC) y la Universidad de Camagüey (UC), en correspondencia con la situación actual y perspectiva de la normativa europea, española y cubana. En el trabajo se realiza una valoración sobre programas experimentales en estructuras mixtas y sus resultados, así como su interrelación con la modelación numérica. Se evalúa la correspondencia entre las normativas europeas, española y cubana y se definen los aspectos específicos que deben ser perfeccionados o complementados en la normatividad vigente en Cuba, así como la estrategia general para acometerlo. Para caracterizar la enseñanza de la construcción mixta en la UPC y la UC, se parte de la valoración de información sobre asignaturas similares en un grupo seleccionado de universidades y sobre el contexto que sirve de marco al perfeccionamiento. Se realiza el diagnostico del sistema de objetivos, conocimientos y organización metodológica en los programas de grado y postgrado y se ofrecen recomendaciones generales para el perfeccionamiento de la enseñanza de la construcción mixta en la UPC y la UC. Finalmente, se realizan propuestas detalladas para ambas instituciones, para el perfeccionamiento de las metodologías docentes, con enfoques generales similares, respetando los criterios específicos y formatos de cada entorno. Se concibe un sistema integrado de actividades para cada asignatura, lográndose que, a pesar de las particularidades de cada contexto, el enfoque de trabajo sea coincidente en gran medida, lo que favorece la continuidad en las relaciones de colaboración entre ambas instituciones.

Trans-Atlantic Pedagogy for Teaching Pre-Service Teachers ICT: Bringing forward cultural issues

Projecte de recerca elaborat a partir d’una estada a la Universitat de Toronto, Canadà, des d’octubre del 2006 a febrer del 2007. El projecte Barchito és un projecte Interrnacional que va involucrar tres universitats: La Universitat Autònoma de Barcelona, la Universitat de Toronto (Canadà) i la Universitat de Roosevelt (USA). El seu objectiu principal era posar en contacte estudiants de les tres universitats (de tres cursos diferents) per discutir al voltant de temes com ara l'ensenyament/aprenentatge i elements culturals de cada país. Aquest projecte presenta la natura de l'experiència des de la visió dels participants: alumnat i professorat. Superant diferències inicials de llengua, els participants van aprendre d'altra cultura, van aprendre sobre altres maneres d'ensenyar i van aprendre, en definitiva, sobre ells mateixos. L'eina d'aprenentatge col.laboratiu els va ajudar a sobrepassar el context immediat, emprant per això, l'eina tecnològica anomenada: Knowledge Forum.

Estudi del sistema de constructes en dones víctimes de violència de gènere

Mitjançant les seves experiències, els éssers humans aprenen a construir significats amb els quals donar sentit i organitzar l’entorn físic i social en què es troben immersos. No accedeixen a una realitat vertadera i única sinó que són possibles múltiples construccions de la realitat. Per tant, és necessari elaborar hipòtesis sobre un mateix, els altres i l'entorn. Aquestes hipòtesis personals estan constituïdes per dimensions de significat o constructes, que consisteixen en la captació d’una diferència o en un contrast; implica percebre una discrepància, que s’expressarà en dos pols oposats. Per exemple, construir el significat “fort” implica diferenciar-lo del significat “feble”; a partir d’aquesta dimensió “fort–feble” s'organitzen les experiències classificant-les al llarg d’aquest continuum. Els constructes s’integren en una xarxa constituïnt un sistema. L’experiència clínica evidencia sovint que dones maltractades no reconeixen la violència de gènere. L’experiència d’abús ha de ser detectada, construïda i integrada dins del món dels significats, és a dir, dels constructes, per ser identificada com a tal. Per exemple, és necessari construir la noció d’agressor i de víctima per poder posicionar-hi a un mateix i als altres. L’objectiu d’aquest estudi és explorar el sistema de constructes en dones que pateixen o han patit violència de gènere, centrant-se en la construcció personal de l’abús per identificar els seus constructes i detectar possibles motius que bloquegin el trencament de la relació amb el maltractador o altres possibles solucions. La mostra està constituïda per 36 dones, amb un rang d’edat situat entre els 18 i els 72 anys. La mitjana d’edat es troba al voltant dels 45 anys. La durada d’aquest estudi és de març de 2006 a març de 2007.

Análisis morfométrico de la extremidad anterior en Carnivora

Durante los cuatro años de disfrute de la beca (2006 – 2009) se ha consolidado una base de datos de medidas osteológicas del esqueleto apendicular de numerosas especies del O. Carnivora. Concretamente, se han medido 364 individuos de 126 especies. Los ejemplares pertenecían a las colecciones del Phyletisches Museum (Jena, Alemania), el Museum für Naturkunde (Berlín, Alemania), el Museu de Ciències Naturals de la Ciutadella (Barcelona, España), el Múseum National d'Histoire Naturelle (París, Francia), y el Museo Nacional de Ciencias Naturales (Madrid, España). Asimismo, con estos datos se han estado preparando tres artículos sobre la morfología de ciertos elementos del esqueleto apendicular en carnívoros, dos de los cuales se encuentran actualmente en estado de revisión para su publicación científica. Dos de ellos, "Scapula, habitat and locomotion in Carnivora" y "Size and shape in the carnivore scapula", relacionan la morfología escapular con factores como el tamaño del animal, el tipo de locomoción que presenta y el hábitat en el que se encuentra; el primero mediante metodología multivariante (análisis funcional) y el segundo bajo las nuevas técnicas de morfometría geométrica. El tercer artículo, "Scaling and mechanics in the carnivore calcaneus: A comparison of natural and artificial selection", evalúa el efecto de diferentes tipos de selección, natural frente a artificial, sobre la morfología del calcáneo y su influencia en la biomecánica de este hueso. Finalmente, también se ha desarrollado un estudio experimental sobre la búsqueda de estabilidad durante la locomoción arbórea, cuyos resultados han dado lugar al artículo "The search for stability on narrow supports: An experimental study in cats and dogs", que también se halla bajo revisión actualmente.

A conceptual framework to assess the effectiveness of HIV prevention

Aim: The relative effectiveness of different methods of prevention of HIV transmission is a subject of debate that is renewed with the integration of each new method. The relative weight of values and evidence in decision-making is not always clearly defined. Debate is often confused, as the proponents of different approaches address the issue at different levels of implementation. This paper defines and delineates the successive levels of analysis of effectiveness, and proposes a conceptual framework to clarify debate. Method / Issue: Initially inspired from work on contraceptive effectiveness, a first version of the conceptual framework was published in 1993 with definition of the Condom Effectiveness Matrix (Spencer, 1993). The framework has since integrated and further developed thinking around distinctions made between efficacy and effectiveness and has been applied to HIV prevention in general. Three levels are defined: theoretical effectiveness (ThE), use-effectiveness (UseE) and population use-effectiveness (PopUseE). For example, abstinence and faithfulness, as proposed in the ABC strategy, have relatively high theoretical effectiveness but relatively low effectiveness at subsequent levels of implementation. The reverse is true of circumcision. Each level is associated with specific forms of scientific enquiry and associated research questions: basic and clinical sciences with ThE; clinical and social sciences with UseE; epidemiology and social, economic and political sciences with PopUseE. Similarly, the focus of investigation moves from biological organisms, to the individual at the physiological and then psychological, social and ecological level, and finally takes as perspective populations and societies as a whole. The framework may be applied to analyse issues on any approach. Hence, regarding consideration of HIV treatment as a means of prevention, examples of issues at each level would be: ThE: achieving adequate viral suppression and non-transmission to partners; UseE: facility and degree of adherence to treatment and medical follow-up; PopUseE: perceived validity of strategy, feasibility of achieving adequate population coverage. Discussion: Use of the framework clarifies the questions that need to be addressed at all levels in order to improve effectiveness. Furthermore, the interconnectedness and complementary nature of research from the different scientific disciplines and the relative contribution of each become apparent. The proposed framework could bring greater rationality to the prevention effectiveness debate and facilitate communication between stakeholders.

Error estimate and control in the MSFV method for multiphase flow in porous media

n this paper the iterative MSFV method is extended to include the sequential implicit simulation of time dependent problems involving the solution of a system of pressure-saturation equations. To control numerical errors in simulation results, an error estimate, based on the residual of the MSFV approximate pressure field, is introduced. In the initial time steps in simulation iterations are employed until a specified accuracy in pressure is achieved. This initial solution is then used to improve the localization assumption at later time steps. Additional iterations in pressure solution are employed only when the pressure residual becomes larger than a specified threshold value. Efficiency of the strategy and the error control criteria are numerically investigated. This paper also shows that it is possible to derive an a-priori estimate and control based on the allowed pressure-equation residual to guarantee the desired accuracy in saturation calculation.

Dr Van Hout has been invited by the ICASA network and IASP research team [Drs Geurt van de Glind; Trimbos Institute, The Netherlands; Dr Pieter-Jan Carpentier, ICASA; Josep Antoni Ramos-Quiroga, University of Barcelona, Spain, Professor Dr Frances Levin, University of Columbia, New York, USA and Professor Dr. Wim van den Brink, University of Amsterdam, The Netherlands] to undertake the research protocol for Ireland as part of this European study of the prevalence of ADHD in adult patients referred for treatment of addiction problems. The research team at Waterford Institute of Technology, School of Health Sciences will undertake this national study as part of the International Collaboration on ADHD and Substance Abuse [ICASA] â?~International ADHD in Substance Use Disorders Prevalence Studyâ?T [IASP study]. The International Collaboration on ADHD and Substance Abuse [ICASA] will provide Dr Van Hout and her team with full support from ICASA of the measurement instruments available and a central database at the University of Amsterdam, and will undergo training for procedures for data capture from Dr van de Glind, Trimbos Institute, The Netherlands. Eight European countries (Norway, Sweden, the Netherlands, Belgium, France, Spain, Switzerland and Hungary) USA and Australia have already participated in the first phase of the IASP study, which will close in September 2011. Over 2500 Substance Use Disorder [SUD] patients were sampled with approximately 38% scoring positive on the ADHD screener (ASRS). Of these 2500 patients over 1000 patients were evaluated on ADHD, Depression, Bipolar Disorder, Anti-Social Personality and Borderline Personality Disorder. A preliminary estimate of the prevalence of ADHD in SUD treatment seeking patients was recorded at 20 %. The second phase of study [IASP 2011] will commence in September 2011 for countries including Ireland, South Africa, Egypt and Brazil. Dr Van Hout has also been invited to partake in a systematic review paper on the risk factors for development of SUD in children/adolescents with ADHD in collaboration with the ICASA foundation.This resource was contributed by The National Documentation Centre on Drug Use.

Long-term efficacy and tolerability of flutamide combined with oral contraception in moderate to severe hirsutism: A 12-month, double-blind, parallel clinical trial

OBJECTIVE Our objective was to test the efficacy and tolerability of three doses of flutamide (125, 250, and 375 mg) combined with a triphasic oral contraceptive (ethynylestradiol/levonorgestrel) during 12 months to treat moderate to severe hirsutism in patients with polycystic ovary syndrome or idiopathic hirsutism. DESIGN We conducted a randomized, double-blind, placebo-controlled, parallel clinical trial. PATIENTS A total of 131 premenopausal women, suffering from moderate to severe hirsutism, were randomized to placebo or 125, 250, or 375 mg flutamide daily associated with a triphasic oral contraceptive pill. Hirsutism (Ferriman-Gallwey), acne and seborrhea (Cremoncini), and hormone serum levels were monitored at baseline and at 3 (except hormone serum levels), 6, and 12 months. Side effects and biochemical, hematological, and hepatic parameters were assessed. METHODS We used three-way ANOVA (subject, dose, and visit) with Scheffé adjustment for multiple comparisons or nonparametrical Friedman test and least-squares mean (paired data) and Kruskall-Wallis test for unpaired data analyses. We used chi(2) or Fisher's test for categorical data. RESULTS A total of 119 patients were included in the intention-to-treat analysis. All flutamide doses induced a significant decrease in hirsutism, acne, and seborrhea scores after 12 months compared with placebo without differences among dose levels. Similar related side effects were observed with placebo and 125 mg flutamide (12.5%), and slightly higher with 250 mg (17.3%) and 375 mg (21.2%). No statistically significant differences were observed either among doses or compared with placebo. CONCLUSIONS Flutamide at 125 mg daily during 12 months was the minimum effective dose to diminish hirsutism in patients with polycystic ovary syndrome or with idiopathic hirsutism.

Improvement in growth after two years of growth hormone therapy in very young children born small for gestational age and without spontaneous catch-up growth: results of a multicenter, controlled, randomized, open clinical trial.

CONTEXT GH treatment is effective in children born small for gestational age (SGA); however, its effectiveness and safety in very young SGA children is unknown. OBJECTIVE The aim was to analyze the outcome of very young SGA children treated with GH and followed for 2 yr. The results after 24 months of treatment, compared with a control group without treatment during 12 months followed by 12 months of treatment, are shown. DESIGN We performed a multicenter, controlled, randomized, open trial. SETTINGS The pediatric endocrinology departments of 14 public hospitals in Spain participated in the study. PATIENTS Seventy-six children, aged 2-5 yr born SGA and without catch-up growth, were studied. INTERVENTION Children received GH at 0.06 mg/kg.d for 2 yr (group I) or were followed for 12 months with no treatment and then treated for 12 months (group II). MAIN OUTCOME MEASURES Age, general health status, pubertal stage, bone age, height, weight, biochemical and hormonal analyses, and adverse side effects were determined at biannual check-ups. RESULTS The mean height sd score gain for chronological age in children treated for 24 months (group I) was 2.10, whereas in those treated only during the last 12 months (group II) was 1.43. In both groups, children under 4 yr of age had the greatest gain in growth velocity. No significant acceleration of bone age or side effects related to treatment was seen. CONCLUSION Very young SGA children without spontaneous catch-up growth could benefit from GH treatment because growth was accelerated and no negative side effects were observed.

1954 les cases barates de Vila-roja : memòria d'una desaparició anunciada i les claus del seu valor històric

Estudi de les primeres 150 “cases barates”, o de tipus social que es van edificar al barri de Vila-roja entre el 1954 i el 1957, anomenades Grup “San Daniel”, i que varen representar l'inici d'aquest barri de Girona. L'estudi incideix en la gestació, en la transformació i en la desaparició progressiva de la fesomia inicial d'aquest barri de Girona projectat i dissenyat per l’arquitecte gironí Ignasi Bosch Reitg (1910-1985), que també fou l’arquitecte del Grup Sant Narcís, de Germans Sàbat i de Sant Cugat a Salt

Novel (60%) and recurrent (40%) androgen receptor gene mutations in a series of 59 patients with a 46,XY disorder of sex development.

BACKGROUND Androgen receptor (AR) gene mutations are the most frequent cause of 46,XY disorders of sex development (DSD) and are associated with a variety of phenotypes, ranging from phenotypic women [complete androgen insensitivity syndrome (CAIS)] to milder degrees of undervirilization (partial form or PAIS) or men with only infertility (mild form or MAIS). OBJECTIVE The aim of the study was to characterize the contribution of the AR gene to the molecular cause of 46,XY DSD in a series of Spanish patients. SETTING We studied a series of 133 index patients with 46,XY DSD in whom gonads were differentiated as testes, with phenotypes including varying degrees of undervirilization, and in whom the AR gene was the first candidate for a molecular analysis. METHODS The AR gene was sequenced (exons 1 to 8 with intronic flanking regions) in all patients and in family members of 61% of AR-mutated gene patients. RESULTS AR gene mutations were found in 59 individuals (44.4% of index patients), of whom 46 (78%) were CAIS and 13 (22%) PAIS. Fifty-seven different mutations were found: 21.0% located in exon 1, 15.8% in exons 2 and 3, 57.9% in exons 4-8, and 5.3% intronic. Twenty-three mutations (40.4%) had been previously described and 34 (59.6%) were novel. CONCLUSIONS AR gene mutation is the most frequent cause of 46,XY DSD, with a clearly higher frequency in the complete phenotype. Mutations spread along the whole coding sequence, including exon 1. This series shows that 60% of mutations detected during the period 2002-2009 were novel.
