Departamento de Estadística) ; Cepeda-Cuervo, Edilberto (Universidad Nacional de Colombia. Departamento de Estadística) ; Núñez-Antón, Vicente. (Universidad del País Vasco. Departamento de Economía Aplicada III (Econometría y Estadística))
An important problem in Statistics is the study of longitudinal data taking into account the effect of other explanatory variables, such as treatments and time and, simultaneously, the incorporation into the model of the time dependence between observations on the same individual. [...]

17 p, 244.6 KB "Sampleo" de textos coloniales en "Concierto barroco" de Alejo Carpentier / Garí Barceló, Bernat (Universitat de Barcelona)
El presente estudio pone de manifiesto que existen filiaciones entre la producción narrativa de Alejo Carpentier y su ensayística literaria. El ensayo literario de Carpentier, tardío cronológicamente en el conjunto de su obra, desempeña una labor exegética y alumbra técnicas, recursos narratológicos y rasgos escrituitarios que fueron el caldo de cultivo de la novelística autoral. [...]
The present article reveals the existing filiation between the narrative production of Alejo Carpentier and his literary essays. Carpentier's literary essay, a late genre in the chronology of his whole corpus, plays an exegetical role and illuminates techniques, narratological resources, and Scriptural traits which were the breeding ground of the authorial novel. [...]

The interaction of single nucleotide polymorphisms with both distal and proximal environmental factors across the extended psychosis phenotype is understudied. This study examined (i) the interaction of relevant SNPs with both early-life adversity and proximal (momentary) stress on psychotic experiences (PEs) in an extended psychosis sample; and (ii) differences between early-psychosis and non-clinical groups for these interactions.

The way in which attachment styles are expressed in the moment as individuals navigate their real-life settings has remained an area largely untapped by attachment research. The present study examined how adult attachment styles are expressed in daily life using experience sampling methodology (ESM) in a sample of 206 Spanish young adults. [...]

12 p, 1.1 MB Cotxe intel·ligent de la Freescale Cup / Herrera Corredera, Aitor ; Senar Rosell, Miquel Àngel, dir. (Universitat Autònoma de Barcelona. Departament d'Arquitectura de Computadors i Sistemes Operatius) ; Universitat Autònoma de Barcelona. Escola d'Enginyeria
La Freescale Cup és una competició de cotxes autònoms en la qual els estudiants de diferents universitats, tots amb el mateix cotxe que proporciona Freescale, programen un algorisme de comportament que fa que aquest cotxe sigui capaç de recórrer un circuit marcat per una línia negra sense cap tipus de comandament humà directe. [...]

Esta tesis doctoral aborda la aplicación de seis enfoques estadísticos que se utilizan para estimar tamaños de muestra en poblaciones multinomiales los que corresponden a: Angers (1974), Tortora (1978), Thompson (1987), Cochran (1977), Bromaghin (1993) y Fitzpatrick & Scott (1987), dichos enfoques están ampliamente discutidos en la literatura del muestreo estadístico pero generan controversia al momento de aplicarlos en estudios de salud dado a que no siempre permiten conjugar costos, representatividad y tamaños de muestra adecuados para un esquema de muestreo aleatorio simple y muestreo complejo de poblaciones en donde la variable de diseño o estudio corresponde a una distribución de tipo multinomial.

This dissertation addresses the application of six statistical approaches used to estimate sample sizes in multinomial populations which correspond to: Angers (1974), Tortora (1978), Thompson (1987), Cochran (1977), Bromaghin (1993) and Fitzpatrick & Scott (1987), such approaches are widely discussed in the literature of statistical sampling but generated controversy when applying in health studies because they do not always allow combining costs, representation and adequate sample sizes for sampling scheme simple random sampling and complex populations where the design variable or study corresponds to a multinomial distribution type.
