El control de qualitat terapèutica i el monitoratge de l’efecte d’aprenentatge constitueixen dues responsabilitats ineludibles durant l’adquisició i manteniment de noves modalitats terapèutiques. L’objectiu d’aquest estudi va ser avaluar qualitat terapèutica i efecte d’aprenentatge a partir de corbes CUSUM, associats a la introducció i desenvolupament de procediments endovasculars incloent 553 pacients consecutius amb arteriopatia obliterant aorto-ilíaca, fémoro-poplítia o renal, tractats per cirurgians vasculars a l’Hospital del Mar entre 2003-2009, registrant-ne iatrogènia, no consecució tècnica i fracàs tècnic durant el primer mes i realitzant corbes CUSUM per a cada territori, que han acabat constituint un excel•lent sistema d’avaluació de qualitat terapèutica.

Report for the scientific sojourn at the Instituto de Biociências, of the Universidade de Sao Paulo, Brazil, from 2007 to 2009. African exotic grasses, used as forage crops for cattle, found optimal conditions in Brazilian savannas for their spread. They established as invasive grasses in almost all conservation units, becoming a serius threat to native biote and to most ecological processes. Fire is a cyclical event in Brazilian savannas and can be used as a management tool for enhancing competitivity of native grasses and controlling exotic grasses. Seeking for alternatives for the management of these grasses, this study investigates the effect of recurrent burnings in different periods of the year (fire regimes) on: distribution patterns of exotic grasses and their associations wotih native grasses, the local edaphic characteristics, the nutrient pool of the aerial biomass of both native and exotic grasses, and soil seed banks. This project is held on the IBGE Ecological Reserve, in Brasília (Brazil), in an area destined specifically for research of fire effects on brazilian savannas. The project quantifies: aerial biomass of native and exotic grasses, soil seed bank of exotic grasses, nutrient pool in soil and also in grasses tissues. Spatial relationships for any association between species, as well as for nutrient pools in soil and in plant tissues will be established. A better understanding of these processes will provide useful tools for adopting specific policies on the management of exotic grasses in Brazilian savanna.

What allows an armed group in a civil war to prevent desertion? This paper addresses this question with a focus on control in the rearguard. Most past studies focus on motivations for desertion. They explain desertion in terms of where soldiers stand in relation to the macro themes of the war, or in terms of an inability to provide positive incentives to overcome the collective action problem. However, since individuals decide whether and how to participate in civil wars for multiple reasons, responding to a variety of local conditions in an environment of threat and violence, a focus only on macro-level motivations is incomplete. The opportunities side of the ledger deserves more attention. I therefore turn my attention to how control by an armed group eliminates soldiers’ opportunities to desert. In particular, I consider the control that an armed group maintains over soldiers’ hometowns, treating geographic terrain as an important exogenous indicator of the ease of control. Rough terrain at home affords soldiers and their families and friends advantages in ease of hiding, the difficulty of using force, and local knowledge. Based on an original dataset of soldiers from Santander Province in the Spanish Civil War, gathered from archival sources, I find statistical evidence that the rougher the terrain in a soldier’s home municipality, the more likely he is to desert. I find complementary qualitative evidence indicating that soldiers from rough-terrain communities took active advantage of their greater opportunities for evasion. This finding has important implications for the way observers interpret different soldiers’ decisions to desert or remain fighting, for the prospect that structural factors may shape the cohesion of armed groups, and for the possibility that local knowledge may be a double-edged sword, making soldiers simultaneously good at fighting and good at deserting.

L'objectiu d'aquest estudi és comparar la propaganda dels totalitarismes soviètic i nazi amb les novel•les d'Un Món Feliç (Aldous Huxley) i 1984 (George Orwell). D'aquesta manera, demostrem que la manipulació i el control dels sistemes descrits en cada llibre són equiparables a la història real.

L’objectiu principal va ser determinar la proporció d’ansietat i/o depressió en una població asmàtica en comparació amb una no asmàtica en atenció primària. Objectius secundaris: valorar si existeix associació entre la gravetat i el grau de control de l’asma i la presència d’ansietat i/o depressió. És un estudi descriptiu transversal amb 317 asmàtics i 306 pacients no asmàtics, entre 17 i 70 anys. A tots els pacients inclosos se’ls va administrar el test de Goldberg. Es va observar que els asmàtics presenten major ansietat i depressió. Un major grau de control de l’asma es va associar a menor ansietat i depressió.

Introducción: el principal tratamiento del carcinoma basocelular (CBC) es la extirpación quirúrgica. Objetivo: determinar la prevalencia de márgenes afectados por el tumor, globalmente y en función del especialista que lo interviene. Métodos: se realizó un estudio retrospectivo de de los informes histológicos de CBC (enero de 2009 - marzo de 2010), un análisis estadístico (Chi-cuadrado de Pearson, U de Mann-Whitney, test de Kruskal-Wallis) y multivariable mediante regresión
