María Magdalena. Continuidad y variación en la cultura audiovisual (1897-2014)

2017

El objetivo principal de esta tesis consiste en analizar la presencia de María Magdalena en las producciones audiovisuales del periodo comprendido entre 1897 y 2014. Dichas producciones proceden de Europa, Estados Unidos, Canadá y México. El marco metodológico general a partir del que se plantea el análisis es la iconología, entendida como Zwichenraum o tierra de confluencias. En concreto, la noción de continuidad y variación, iniciada por Aby Warburg y continuada por Fritz Saxl, es la principal cuestión teórica en la que se basa la aproximación. El estudio se lleva a cabo en perspectiva diacrónica con el objetivo de detectar dichas fases de continuidad y variación del personaje a lo largo …

Cannabis users have higher premorbid IQ than other patients with first onset psychosis.

2013

Background: A number of studies have reported that patients with psychosis who use cannabis have better cognitive performance than those who do not. This is surprising as cannabis can impair cognition in healthy subjects. An obvious question is whether the better current performance of psychotic patients who have used cannabis is a reflection of their having a higher premorbid IQ than those psychotic patients who haven't used cannabis. Aim: In a sample of patients at their first episode of psychosis, we tested the hypothesis that patients who smoked cannabis would have a higher premorbid IQ than patients who did not. Methodology: 279 participants (119 patients and 160 healthy controls) were…

Cannabis Users and Premorbid Intellectual Quotient (IQ)‏

2017

• The chapter focuses on premorbid Intellectual Quotient (IQ) in cannabis users, one of the most controversial topics in studies on the harmful effects of cannabis use on cognition. • Several studies have ascertained acute and residual effects of cannabis use in the memory domain, but only a minimal general cognitive effect after a long-term period of abstinence. • A number of longitudinal studies were able to obtain IQ measures before and after cannabis consumption, but they yielded discordant findings. • Authors, however, observed a relationship between higher premorbid IQ and recreational or discontinued use while a lower premorbid IQ resulted as a predictor for regular or heavy cannabis…

PATIENTS WITH THEIR FIRST EPISODE OF PSYCHOSIS (FEP) WHO USE CANNABIS HAVE NORMAL PREMORBID IQ

2012

Cannabis use is highly prevalent among people with schizophrenia and, coupled with impaired cognition, is thought to heighten the risk of illness onset. Paradoxically, several studies report lifetime cannabis use as a predictor of a better cognitive performance in psychotic patients. This case/control study was conducted in order to observe in a First Episode group the association between cannabis use lifetime and two measures of general cognition: current and pre-morbid IQ. The data are derived from the GAP study, a case-control study of first-episode psychosis (FEP) - South London and Maudsley Mental Health NHS Foundation Trust. 279 consenting subjects: 119 FEP patients (age 29.6±8.5; 70%…

The relationship between ADHD and key cognitive phenotypes is not mediated by shared familial effects with IQ

2011

BackgroundTwin and sibling studies have identified specific cognitive phenotypes that may mediate the association between genes and the clinical symptoms of attention deficit hyperactivity disorder (ADHD). ADHD is also associated with lower IQ scores. We aimed to investigate whether the familial association between measures of cognitive performance and the clinical diagnosis of ADHD is mediated through shared familial influences with IQ.MethodMultivariate familial models were run on data from 1265 individuals aged 6–18 years, comprising 920 participants from ADHD sibling pairs and 345 control participants. Cognitive assessments included a four-choice reaction time (RT) task, a go/no-go task…

P.0170 Distinct polygenic risk scores in clusters of psychotic subjects with different premorbid trajectories and current IQ

T42. JUMPING TO CONCLUSIONS IS ASSOCIATED WITH THE POLYGENIC RISK SCORE FOR INTELLIGENCE BUT NOT FOR SCHIZOPHRENIA. PRELIMINARY FINDINGS FROM THE EU-…

2019

Background Psychotic patients tend to require less evidence to make decisions compared to general population. This bias named Jumping to Conclusions (JTC) has been found at First Episode Psychosis (FEP) in schizophrenia patients and associated with proneness to psychotic-like experiences in the general population. Interesting findings showed also strong association with lower cognitive functioning in psychotic patients, which in turn has been shown as a candidate intermediate phenotype for psychosis. Overall, findings to date could suggest a shared genetic liability between the occurrence of JTC and psychosis, potentially via IQ. The present study aims to investigate whether the presence of…

The Rail Quality Index as an Indicator of the “Global Comfort” in Optimizing Safety, Quality and Efficiency in Railway Rails

2012

AbstractThe proposed model uses the stochastic dynamic programming and in particular Markov decision processes applied to the Rail Quality Index (RQI - Italian Indice di Qualità del Binario, IQB).By performing the integrated analysis of the classes of variables which characterize the overall service quality (in terms of comfort and safety), the proposed mathematical approach allows to find the solutions to the decision-making process in function of the probability of deterioration of the state variables of the infrastructure over time and of the flow of available resources.
