La Construcción Subjetiva de las Consecuencias del Encarcelamiento: el Punto de Vista del Recluso

Research in prisons usually focuses on the presence of psychopathology in prisoners. In our study, we focuse on the identity construction of the prisoner; specifically, we focus on how affects prisoners to stay in prison. To do this, we interviewed five prisoners, to whom we have administered the Repertory Grid Technique (Kelly, 1955/1991). We propose three elements for the Repertory Grid: I-before entering prison, I- being in prison and I when I’ll released from prison; the other elements were elicited by the participants. The personal construct analysis of every prisoner’s Grid, by means of the Record V.4.0. program, offers insight into the impact it has had being imprisoned on the construction of the identity of the prisoner. It also allows us to know how the prisoner anticipates their life in freedom.ResumenLa investigación en el ámbito penitenciario suele centrarse en la presencia de psicopatología en los presos. En nuestro estudio, nos centramos en la construcción de la identidad del recluso, específicamente en cómo le influye la estancia en prisión. Para ello entrevistamos a cinco presos, administrándoles la técnica de la Rejilla (Kelly, 1955/1991). En el diseño de ésta, proponemos tres elementos: Yo-antes de entrar en prisión, Yo-en prisión y Yo-cuando salga de prisión; el resto de elementos fueron elicitados por los participantes. El análisis de los constructos personales de cada recluso, mediante el programa Record V.4.0, nos permite conocer las consecuencias que tiene para la construcción de la identidad del recluso el hecho de estar encarcelado, así como conocer la anticipación que hace de su vida en libertad. AbstractResearch in prisons usually focuses on the presence of psychopathology in prisoners.

El incremento de mindfulness con el ejercicio de la psicoterapia

Research on Mindfulness often focuses on the benefits to the patient, but analyzing its definition we can see the similarities that can be found with relational Rogerian skills (Rogers, 1951). In this study, the relationship between constructivist therapists years of experience and the rising of their mindfulness capacity is analyzed. We administered the scale MAAS (Brown & Ryan, 2003) to constructivist psychotherapists. 15 of theme were  novice (less than 5 years of experience) and 22 of them were expert (over 8 years of experience). Comparing the results of both groups allow us to state that expert constructivist psychotherapists have more capacity of mindfulness than novices.ResumenLa investigación sobre Mindfulness suele centrarse en los beneficios que aporta al paciente pero analizando su definición observamos las similitudes que se pueden encontrar con las competencias relacionales rogerianas (Rogers, 1951).En este estudio analizaremos la relación que existe entre los años de experiencia de los terapeutas constructivistas y el incremento en su capacidad de mindfulness.

A case study on cooperative car data for traffic state estimation in an urban network

The use of Floating Car Data (FCD) as a particular case of Probe Vehicle Data (PVD) has been the object of extensive research for estimating traffic conditions, travel times and Origin to Destination trip matrices. It is based on data collected from a GPS-equipped vehicle fleet or available cell phones. Cooperative Cars with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication capabilities represent a step forward, as they also allow tracking vehicles surrounding the equipped car. This paper presents the results of a limited experiment with a small fleet of cooperative cars in Barcelona’s Central Business District (CBD) known as L’Eixample. Data collected from the experiment were used to build and calibrate the emulation of cooperative functions in a microscopic simulation model that captured the behavior of vehicle sensors in Barcelona’s CBD. Such a calibrated model allows emulating fleet data on a large scale that goes far beyond what a small fleet of cooperative vehicles could capture. To determine the traffic state, several approaches are developed for estimating traffic variables based on extensions of Edie’s definition of the fundamental traffic variables with the emulated data, whose accuracy depends on the penetration level of the technology.Peer ReviewedPostprint (author's final draft

Incorporating advanced behavioral models in mixed linear optimization

Discrete choice models are the state-of-the-art for the mathematical modelling of demand. Based on the concept of random utility, they are able to predict the choice behavior of individuals. However, these models are highly non linear and non convex in the variables of interest, and therefore difficult to be included in mixed linear optimization models. These models are of great importance in transportation revenue management systems. In this research, we propose a new mathematical modeling framework to include general random utility assumption inside discrete optimization framework. In order to tackle the nonlinearity and non-convexity imposed by choice-models, we rely on simulation to capture the probabilistic nature of demand. Since the formulation has been designed to be linear, the price to pay is the high dimensionality of the problem. We have performed some preliminary experiments for small instances with promising results. Nevertheless, for more general cases, additional techniques as decomposition methods may be required

A new mathematical formulation to integrate supply and demand within a choice-based optimization framework

Discrete choice models are the state-of-the-art for the mathematical modeling of demand. Based on the concept of random utility, they are able to predict the choice behavior of individuals. However, these models are highly non linear and non convex in the variables of interest, and therefore difficult to be included in mixed linear optimization models. Furthermore, these models are of great importance in transportation revenue management systems. In this research, we propose a new mathematical modeling framework to include general random utility assumption inside discrete optimization framework. In order to tackle the non-linearity and non-convexity imposed by choice-models, we rely on simulation to capture the probabilistic nature of demand. Since the formulation has been designed to be linear, the price to pay is the high dimensionality of the problem. We propose an alternative formulation aiming at reducing the size of the problem. We have performed some preliminary experiments for small instances in order to compare the performances of the two models. Note that regardless from the implemented formulation, additional techniques such as decomposition methods may be required for more general instances
