Slope processes in changing permafrost environments: a geomorphological and sedimentological approach

Estudi realitzat a partir d’una estada al Centro de Estudos Geograficos de la Universidade de Lisboa, Portugal, entre 2011 i 2012. En aquest grup he desenvolupat la meva recerca focalitzada en ambients polars en presència de permafrost, concretament centrada en l’extrem nord-occidental de la Península Antàrtica (Shetland del Sud) i a l’Alt Àrtic (Svalvard). Ambdós àrees han registrat un augment de temperatura molt significatiu les darreres dècades. La meva recerca ha contemplat l’anàlisi de registres sedimentaris (lacustres, eòlics, vessant) i la monitorització de processos geomorfològics actuals a fi efecte d’entendre la dinàmica ambiental present i passada (i.e. clima). Amb aquesta finalitat he realitzat tres campanyes de treball de camp a l’Antàrtida i dues a l’Àrtic. El posterior treball de laboratori i d’oficina està propiciant nombroses publicacions que donen fe dels èxits assolits. A més, cal enfatitzar altres activitats desenvolupades durant la BP-A: coneixement de com organitzar i gestionar una campanya antàrtica, docència universitària, participació en comitès, associacions i tribunals de tesis doctorals, organització i participació en nombroses conferències, treball de camp en noves àrees d’estudi, referee per revistes internacionals, etc. Tanmateix, la concessió del projecte de recerca HOLOANTAR, del qual en sóc l’Investigador Responsable, ha estat l’èxit més important d’aquesta estada. Aquest projecte m’està conferint la capacitat de gestionar i integrar la recerca de 16 investigadors de diferents nacionalitats des d’una perspectiva multidisciplinar. Tothora, cal remarcar que no s’ha assolit un dels èxits que pretenia el meu projecte de BP-A: la transferència del bagatge i coneixement adquirit al sistema de recerca català. Malgrat haver presentat la meva candidatura per un contracte BP-B per tal que aquest background après a l’estranger revertís a Catalunya, el procés de selecció emprat en la convocatòria ho ha impedit i m’obliga a continuar la meva recerca a l’estranger.

Activities of fluconazole, caspofungin, anidulafungin, and amphotericin B on planktonic and biofilm Candida species determined by microcalorimetry.

We investigated the activities of fluconazole, caspofungin, anidulafungin, and amphotericin B against Candida species in planktonic form and biofilms using a highly sensitive assay measuring growth-related heat production (microcalorimetry). C. albicans, C. glabrata, C. krusei, and C. parapsilosis were tested, and MICs were determined by the broth microdilution method. The antifungal activities were determined by isothermal microcalorimetry at 37°C in RPMI 1640. For planktonic Candida, heat flow was measured in the presence of antifungal dilutions for 24 h. Candida biofilm was formed on porous glass beads for 24 h and exposed to serial dilutions of antifungals for 24 h, and heat flow was measured for 48 h. The minimum heat inhibitory concentration (MHIC) was defined as the lowest antifungal concentration reducing the heat flow peak by ≥50% (≥90% for amphotericin B) at 24 h for planktonic Candida and at 48 h for Candida biofilms (measured also at 24 h). Fluconazole (planktonic MHICs, 0.25 to >512 μg/ml) and amphotericin B (planktonic MHICs, 0.25 to 1 μg/ml) showed higher MHICs than anidulafungin (planktonic MHICs, 0.015 to 0.5 μg/ml) and caspofungin (planktonic MHICs, 0.125 to 0.5 μg/ml). Against Candida species in biofilms, fluconazole's activity was reduced by >1,000-fold compared to its activity against the planktonic counterparts, whereas echinocandins and amphotericin B mainly preserved their activities. Fluconazole induced growth of planktonic C. krusei at sub-MICs. At high concentrations of caspofungin (>4 μg/ml), paradoxical growth of planktonic C. albicans and C. glabrata was observed. Microcalorimetry enabled real-time evaluation of antifungal activities against planktonic and biofilm Candida organisms. It can be used in the future to evaluate new antifungals and antifungal combinations and to study resistant strains.

Nursing Activities Score (NAS): adaptação transcultural e validação para a língua portuguesa

O estudo teve como objetivos adaptar para o português e avaliar as propriedades psicométricas do Nursing Activities Score (NAS), instrumento de medida de carga de trabalho de enfermagem em UTI. Após o processo de adaptação cultural, o NAS foi aplicado em uma amostra de 200 pacientes adultos internados em UTIs. A análise da consistência interna pelo coeficiente Alfa de Cronbach revelou que o NAS possui 23 medidas independentes que não comportam consolidação ou redução. A avaliação da confiabilidade interobservadores demonstrou alta concordância (99,8%) e índice Kappa médio de 0,99. A validade concorrente foi demonstrada pela correlação estatisticamente significativa entre o TISS-28 e o NAS (r=0,67; p<0,0001), assim como pela análise de regressão multivariada (R²=94,4%; p<0,0001). Na avaliação da validade convergente, a regressão multivariada mostrou associação estatisticamente significativa entre o NAS e o SAPS II, quando ajustada pela idade (R²=99,8%; p<0,0001). Pelos resultados obtidos, o NAS mostrou-se um instrumento confiável e válido para mensurar carga de trabalho de enfermagem em UTIs brasileiras.

Organizational resources and intrapreneurial activities: a cross-country study

The importance of entrepreneurship for social and economic growth is generally accepted. In addition, intrapreneurship or corporate entrepreneurship is recognized as one of the key elements for organizational development. In this context, corporate culture and, specifically, entrepreneurial competences are considered to be catalysts for intrapreneurship. The main purpose of this paper is to analyse the influence of resources and capabilities on the probability of becoming an intrapreneur. Using data obtained from the Global Entrepreneurship Monitor (GEM) for 39 countries, and a logistic model, the study shows that entrepreneurial resources and capabilities, such as previous entrepreneurial experience, entrepreneurial competences and the ability to detect business opportunities, influence intrapreneurial behaviour. The contributions of this research are both conceptual (advancing corporate entrepreneurship theory) and practical (relating to the design of policies to foster intrapreneurial activities).

Plastinated Ethmoidal Region : II. The Preparation and Use of Radio-Opaque Artery Casts in Clinical Teaching.

In endoscopic sinus surgery, knowledge of the course of the internal ethmoida and orbital arteries is crucial.The maxillary and the internal carotid arteries of cadavers were injected with radio-opaque , red colorede silicone. The ethmoidal regions were perpared and plastinated using the standard S10 technique. On some specimens, the ophtalmic and ethmoidal arteries were dissected prior to plastination. The plastinated specimens of the ethmoidal blocks were successfullyintroduced into clinical teaching of sinus anatomy and surgery as an aid to study vaascularization an dits relationship to surgical procedures. Among the advantages of this method are the long-lasting preservation of dissected tissue, visualization of arteries during endoscopic and radiological examinations, and invaluable teachjing and training resources for endoscopic sinus surgery.

Market rewards to patterns on increasing earnings: do cash flow patterns, accruals manipulation and real activities manipulation matter?

This study explores whether firms have differential price-earnings multiples associated with their means of achieving a sequential pattern of increasing positive earnings. Our main findings show that market participants assign higher price-earnings multiples to firms when their pattern of increasing earnings is supported by the same pattern of increasing cash flows. Market participants assign lower price-earnings multiples to firms suspect of having engaged in accrual-based earnings management, sales manipulation, and overproduction to achieve the earnings pattern. We find, however, that market participants do not penalize firms suspect of having achieved the earnings pattern through the opportunistic reduction of discretionary expenses.

La evaluación como elemento clave de la formación basada en competencias: tres casos en el ámbito de la ingenierías

El Espacio Europeo de Educación Superior implica cambios organizativos y académicos referentes a la formación basada en competencias. El proyecto AlineaME, coordinado por la Unidad de Soporte a la Calidad y la Innovación Docente de la Escuela Superior Politécnica - Universidad Pompeu Fabra, propuso a docentes del área TIC y a pedagogos la reflexión conjunta en aras a diseñar recomendaciones centradas en la alineación entre los tres elementos clave del proyecto: competencias, metodología y evaluación (C*M*E). Este trabajo recoge tres casos de aplicación de recomendaciones, concretamente de Ingeniería Telemática (dos casos - Universidad de Valladolid y Pompeu Fabra) y de Ingeniería Técnica en Informática de Gestión (un caso - Universidad de Sevilla).Las recomendaciones aplicadas hacen referencia a la necesidad de explicitar la alineación C*M*E en los Planes Docentes de Asignaturas y de presentar esta alineación al estudiantado. También a la integración de la evaluación de la asignatura como tarea-proceso de aprendizaje. La metodología seguida para laaplicación de ambas es (salvo pequeñas diferencias) parecida en los tres casos. La primera recomendación consistió en recoger en el Plan Docente la Alineación y en verbalizar dicha alineación en la sesión de presentación de la asignatura. La segunda se incorporó incluyendo actividades formativas en las que se favorecía la evaluación entre iguales. Para evaluar la aplicación de recomendaciones se recogieron evidencias en clave de satisfacción por parte del estudiantado así como valoraciones de los propios docentes. Para ello se diseñaron instrumentos específicos.En cuanto a la presentación de la alineación C*M*E en los Planes Docentes de asignaturas, los resultados indican que los alumnos son más conscientes de qué, cómo y por qué van a trabajar y ser evaluados. Globalmente valoran positivamente su utilidad para la autorregulación. Asimismo, plantear la evaluación como tarea deaprendizaje resultó ser para los estudiantes un interesante elemento de reflexión.

Monitoring of posture allocations and activities by a shoe-based wearable sensor.

Monitoring of posture allocations and activities enables accurate estimation of energy expenditure and may aid in obesity prevention and treatment. At present, accurate devices rely on multiple sensors distributed on the body and thus may be too obtrusive for everyday use. This paper presents a novel wearable sensor, which is capable of very accurate recognition of common postures and activities. The patterns of heel acceleration and plantar pressure uniquely characterize postures and typical activities while requiring minimal preprocessing and no feature extraction. The shoe sensor was tested in nine adults performing sitting and standing postures and while walking, running, stair ascent/descent and cycling. Support vector machines (SVMs) were used for classification. A fourfold validation of a six-class subject-independent group model showed 95.2% average accuracy of posture/activity classification on full sensor set and over 98% on optimized sensor set. Using a combination of acceleration/pressure also enabled a pronounced reduction of the sampling frequency (25 to 1 Hz) without significant loss of accuracy (98% versus 93%). Subjects had shoe sizes (US) M9.5-11 and W7-9 and body mass index from 18.1 to 39.4 kg/m2 and thus suggesting that the device can be used by individuals with varying anthropometric characteristics.

In vitro and in vivo Repair Activities of Undifferentiated and Classically and Alternatively Activated Macrophages.

Objective: Macrophages play a critical role in wound repair. However, the specific role of the different macrophage subtypes in wound repair remains incompletely understood. The aim of this study was to compare the wound repair activities of undifferentiated macrophages (M0), classically activated macrophages (M1) and alternatively activated (M2) macrophages. Methods: The macrophage repair activities of intestinal wounds were evaluated using in vitro and in vivo models. Results: All three macrophage subtypes enhanced wound closure in vitro, with the M2 macrophages demonstrating greater repair activities than the M0 and M1 macrophages. Injection of M0 and M2 macrophages into mice with experimental dextran sodium sulfate-induced colitis significantly enhanced ulcer repair when compared to control mice. In contrast, injection of M1 macrophages did not affect ulcer repair. Conclusions: These results underscore the wound repair capacity of different macrophage subsets. Notably, wound repair activity is not restricted to M2 macrophages, as the current literature suggests. © 2014 S. Karger AG, Basel.

Teaching motivational interviewing to medical students : a pre-post test pilot study

Objective: To test the efficacy of teaching motivational interviewing (MI) to medical students. Methods: Thirteen 4th year medical students volunteered to participate. Seven days before and 7 days after an 8-hour interactive training MI workshop, each student performed a videorecorded interview with two standardized patients: a 60 year old alcohol dependent woman and a 50 year old cigarette smoking man. Students' counseling skills were coded by two blinded clinicians using the Motivational Interviewing Treatment Integrity 3.0 (MITI). Inter-rater reliability was calculated for all interviews and a test-retest was completed in a sub-sample of 10 consecutive interviews three days apart. Difference between MITI scores before and after training were calculated and tested using non-parametric tests. Effect size was approximated by calculating the probability that posttest scores are greater than pretest scores (P*=P(Pre<Post)+1/2P(Pre=Post)), P*>1/2 indicating greater scores in posttest, P*=1/2 no effect, and P*<1/2 smaller scores in posttest. Results: Median differences between MITI scores before and after MI training indicated a general progression in MI skills: MI spirit global score (median difference=1.5, Inter quartile range=1.5, p<0.001, P*=0.90); Empathy global score (med diff=1, IQR=0.5, p<0.001, P*=0.85); Percentage of MI adherent skills (med diff=36.6, IQR=50.5, p<0.001, P*=0.85); Percentage of open questions (med diff=18.6, IQR=21.6, p<0.001, P*=0.96); reflections/ questions ratio (med diff=0.2, IQR=0.4, p<0.001, P*=0.81). Only Direction global score and the percentage of complex reflections were not significantly improved (med diff=0, IQR=1, p=0.53, P*=0.44, and med diff=4.3, IQR=24.8, p=0.48, P*=0.62, respectively). Inter-rater reliability indicated weighted kappa ranged between 0.14 for Direction to 0.51 for Collaboration and ICC ranged between 0.28 for Simple reflection to 0.95 for Closed question. Test-retests indicated weighted kappa ranged between 0.27 for Direction to 0.80 for Empathy and ICC ranged between 0.87 for Complex reflection to 0.98 for Closed question. Conclusion: This pilot study indicated that an 8-hour training in MI for voluntary 4th year medical students resulted in significant improvement of MI skills. Larger sample of unselected medical students should be studied to generalize the benefit of MI training to medical students. Interrater reliability and test-retests suggested that coders' training should be intensified.

Paternal involvement and children's developmental stages in Spain

How does fathering change across children’s developmental stages and how do these changes vary by educational levels and women’s employment? To investigate this, I use the „2003 Spanish Time Use Survey‟ (N = 2,941) for a sample of heterosexual couples with children of different ages. I differentiate between physical (i.e. feeding, supervising, putting children to bed) and interactive child care activities (i.e. speaking to, playing with, teaching the child). Fathers‟ education strongly influences how much fathers participate in physical care in families with preschoolers, a stage in which these activities are particularly important for children’s physical, social, and emotional development. For interactive care, a significant education gradient emerges when the youngest child is aged 3 to 5, when the acquisition of complex linguistic, conceptual, and social skills is critical for later school success. Mother’s employment significantly influences father’s physical child care with preschoolers. This suggests that empowering Spanish women to participate in the labor market promotes gender equity in the household division of child care.

Teaching ethnic diversity in journalism school

It has been found that the symbolic elites have a prominent role in the discursive reproduction of racism in society, because they control the public discourse through which many ethnic prejudices are spread and shared. This special position of the mass media requires that the professional education of journalists, also featuring such topics as ethnic studies, diversity and racism, is optimally adapted to the multicultural societies in Europe, North America and Australia. This paper reports about an extensive research project examining ethnic education of journalists in these white-dominated countries, by examining the websites of many journalism and communication departments. Consistent with the general finding that white symbolic elites primarily deny or ignore (their) racism in society, none of the academic programs, anywhere in the world, mentions special classes on racism in the mass media. Finally, a practical proposal is made for a course on ethnic reporting in multicultural societies.
