Las investigaciones de Leo Frobenius y el Forschungsinstitut für Kulturmorphologie (FK) sobre el arte rupestre en España (1934-1936).

Leo Frobenius, fundador del Afrika Archiv y director del Forschungsinstitut für Kulturmorphologie (FK), centró la mayor parte de su actividad etnográfica en la documentación y estudio del arte rupestre. Tras estudiar las obras de Hugo Obermaier sobre el arte parietal en la Península Ibérica, decidió, en 1934, organizar una expedición para documentar los principales yacimientos francocantábricos y del Levante español. En ella se estudiaron tan sólo los yacimientos de Roca dels Moros de Cogul y el Barranco de la Valltorta, pero sirvió de base para la programación de una nueva expedición cuyos objetivos eran mucho más ambiciosos. En 1935, con la ayuda de Obermaier, Bosch Gimpera y Martínez Santa Olalla, y el amparo diplomático de la Embajada de Alemania en Madrid, realizó la petición de acceso a las principales cuevas con arte parietal, permiso que consiguió tras arduas negociaciones. En los meses previos al inicio de la Guerra Civil, un grupo de dibujantes y fotógrafos del FK trabajó en las cuevas de El Castillo, La Pasiega y Altamira, obteniendo copias a escala natural de grabados y pinturas que pasaron a formar parte del archivo del Instituto. En 1938, y como consecuencia del apoyo de Alemania al bando nacional, Martínez Santa Olalla, miembro de la Falange, se convirtió en el referente de Frobenius en España, desplazando a Obermaier. Dicha relación tendría como consecuencia el giro en la política arqueológica de los vencedores de la contienda y su vinculación con la organización Das Ahnenerbe de las SS.

L'ambient urbà i la criminalitat. Robatoris contra el patrimoni a la ciutat de Girona

L’estudi de la criminalitat és multifactorial, cal destriar en la mesura del possible els factorsambientals, d’entorn urbà, que poden jugar el paper de facilitadors de la delinqüència. Lestipologies delictives són diverses i amb motivacions "mòbils" diferenciats, el que confereixdificultats a l’estudi de la criminalitat, és per aquesta raó que es trien dues tipologies derobatoris contra el patrimoni per ser analitzats: robatoris amb força a interior de domicili(vivenda) i els furts, en un marc de ciutat petita-mitjana, com és el cas de Girona. Elconeixement per part de l’autor del marc urbà n’és un part essencial per desenvolupar l’estudi.Un dels objectius finalistes és aconseguir avançar en estudis de diagnosi criminal de les ciutats;així com en el coneixement dels patrons espaials que tenen les tipologies delictives i lainfluència de les característiques del disseny urbà sobre la criminalitat. La metodologia ques’implementarà serà: recerca bibliogràfica, estadística descriptiva i inferencial, sistemesd’informació geogràfica, així com la deducció a partir de la visualització de la cartografiagenerada i un treball de camp de les zones d’alta ocurrència delictiva dels delictes esmentats.Pel que fa a les hipòtesis principals: els robatoris contra el patrimoni no es concentren en àreesdegradades urbanísticament sinó ans el contrari en ambients urbans cuidats. Aquesta hipòtesies contraposa a la teoria criminal de la "Broken Windows", que esmenta que els espais urbansdegradats és on hi ha menys ocupació d’espai públic i més delinqüència. Una altra hipòtesiimportant és que els espais percebuts com a segurs, respecte les tipologies delictivesesmentades, són els més insegurs

Moral hazard and non-exclusive contracts

This paper studies equilibria for economies characterized by moral hazard(hidden action), in which the set of contracts marketed in equilibrium isdetermined by the interaction of financial intermediaries.The crucial aspect of the environment that we study is thatintermediaries are restricted to trade non-exclusive contracts: theagents' contractual relationships with competing intermediaries cannot bemonitored (or are not contractible upon). We fully characterize equilibrium allocations and contracts. In thisset-up equilibrium allocations are clearly incentive constrainedinefficient. A robust property of equilibria with non-exclusivity isthat the contracts issued in equilibrium do not implement the optimalaction. Moreover we prove that, whenever equilibrium contracts doimplement the optimal action, intermediaries make positive profits andequilibrium allocations are third best inefficient (where the definitionof third best efficiency accounts for constraints which capture thenon-exclusivity of contracts).

Systems medicine and integrated care to combat chronic noncommunicable diseases

We propose an innovative, integrated, cost-effective health system to combat major non-communicable diseases (NCDs), including cardiovascular, chronic respiratory, metabolic, rheumatologic and neurologic disorders and cancers, which together are the predominant health problem of the 21st century. This proposed holistic strategy involves comprehensive patient-centered integrated care and multi-scale, multi-modal and multi-level systems approaches to tackle NCDs as a common group of diseases. Rather than studying each disease individually, it will take into account their intertwined gene-environment, socio-economic interactions and co-morbidities that lead to individual-specific complex phenotypes. It will implement a road map for predictive, preventive, personalized and participatory (P4) medicine based on a robust and extensive knowledge management infrastructure that contains individual patient information. It will be supported by strategic partnerships involving all stakeholders, including general practitioners associated with patient-centered care. This systems medicine strategy, which will take a holistic approach to disease, is designed to allow the results to be used globally, taking into account the needs and specificities of local economies and health systems.

Web 2.0 en la docencia universitaria: aprendizaje colaborativo a través de la tecnología

El concepto web 2.0 se utiliza para denominar a un conjunto de aplicaciones que están siempre en evolución de acuerdo a los requerimientos que los usuarios van realizando. En la red podemos encontrar muchas herramientas desarrolladas en la línea de la web 2.0: blogs, wikis, herramientas para compartir marcadores, para compartir archivos, etc. Consideramos que el sistema educativo no puede estar al margen de esta evolución tecnológica y necesita adaptarse a todos los niveles. Las universidades también se encuentran en la necesidad de adecuarse a estos nuevos tiempos, y cada vez encontramos más experiencias formativas de trabajo colaborativo en red para favorecer el aprendizaje de los estudiantes. El trabajo que presentamos es un análisis de herramientas web 2.0 y de una recopilación de buenas prácticas docentes universitarias de desarrollo de metodologías colaborativas utilizando las TIC. Además, ofrecemos recomendaciones del uso de estas herramientas en los procesos de enseñanza y aprendizaje universitario.

Lack of support for the association between facial shape and aggression: a reappraisal based on a worldwide population genetics perspective

Antisocial and criminal behaviors are multifactorial traits whose interpretation relies on multiple disciplines. Since these interpretations may have social, moral and legal implications, a constant review of the evidence is necessary before any scientific claim is considered as truth. A recent study proposed that men with wider faces relative to facial height (fWHR) are more likely to develop unethical behaviour mediated by a psychological sense of power. This research was based on reports suggesting that sexual dimorphism and selection would be responsible for a correlation between fWHR and aggression. Here we show that 4,960 individuals from 94 modern human populations belonging to a vast array of genetic and cultural contexts do not display significant amounts of fWHR sexual dimorphism. Further analyses using populations with associated ethnographical records as well as samples of male prisoners of the Mexico City Federal Penitentiary condemned by crimes of variable level of inter-personal aggression (homicide, robbery, and minor faults) did not show significant evidence, suggesting that populations/individuals with higher levels of bellicosity, aggressive behaviour, or power-mediated behaviour display greater fWHR. Finally, a regression analysis of fWHR on individual"s fitness showed no significant correlation between this facial trait and reproductive success. Overall, our results suggest that facial attributes are poor predictors of aggressive behaviour, or at least, that sexual selection was weak enough to leave a signal on patterns of between- and within-sex and population facial variation.

The transtheoretical model in weight management: Validation of the Processes of Change Questionnaire

Objective: The processes of change implied in weight management remain unclear. The present study aimed to identify these processes by validating a questionnaire designed to assess processes of change (the P-Weight) in line with the transtheoretical model. The relationship of processes of change with stages of change and other external variables is also examined. Methods: Participants were 723 people from community and clinical settings in Barcelona. Their mean age was 32.07 (SD = 14.55) years; most of them were women (75.0%), and their mean BMI was 26.47 (SD = 8.52) kg/m2. They all completed the P-Weight and the stages of change questionnaire (SWeight), both applied to weight management, as well as two subscales from the Eating Disorders Inventory-2 and Eating Attitudes Test-40 questionnaires about the concern with dieting. Results: A 34-item version of the PWeight was obtained by means of a refinement process. The principal components analysis applied to half of the sample identified four processes of change. A confirmatory factor analysis was then carried out with the other half of the sample, revealing that the model of four freely correlated first-order factors showed the best fit (GFI = 0.988, AGFI = 0.986, NFI = 0.986, and SRMR = 0.0559). Corrected item-total correlations (0.322-0.865) and Cronbach"s alpha coefficients (0.781-0.960) were adequate. The relationship between the P-Weight and the S-Weight and the concern with dieting measures from other questionnaires supported the validity of the scale. Conclusion: The study identified processes of change involved in weight management and reports the adequate psychometric properties of the P-Weight. It also reveals the relationship between processes and stages of change and other external variables.
