Developmental trajectories of experiential avoidance and depressive symptoms and association to health behaviors among adolescents during brief guide…
2021
Abstract While many children and adolescents experience psychological problems with up to 20 percent estimated to develop a mental health problem, only few receive treatment. Online interventions can help respond to the need of support among young people without requiring considerable resources. However, relatively few studies have examined the efficacy of online interventions for youth and more research is needed to understand individual differences in benefiting from these interventions. The current study sought to examine different developmental trajectories of experiential avoidance and depressive symptoms and their association to health behaviors measured at baseline during a brief gui…
The debate on medicalization of sexology 2001–2010: a literature study on psychological treatment of sexual problems
2018
The objective of this study is to describe the position of psychological treatment in an era where optimism surrounding pharmacological treatment has raised questions as to whether psychology shoul...
El papel de los problemas emocionales en la hipersexualidad
2020
Introducción: La hipersexualidad es un problema frecuente en la práctica clínica, especialmente por el malestar emocional que generan algunas de sus manifestaciones como la adicción al sexo. Sin embargo, la relación entre el malestar y la hipersexualidad no está clara y muchos autores resaltan que, además de una consecuencia, el malestar emocional podría ser causante de la búsqueda del sexo como una estrategia de regulación emocional. El objetivo del presente estudio es comprobar si existe relación entre el estado anímico y la conducta hipersexual tanto en hombres como en mujeres. Método: 400 participantes (69% hombres) entre los 18 y 40 años (M=26,65; DT=6,30) completaron una encuesta onli…
Psychological treatment of sexual problems. Thematic analysis of guidelines and recommendations, based on a systematic literature review 2001–2010
2015
ABSTRACTIn order to explore the basis for evaluation of quality in psychological treatment of sexual problems, a literature search, confined to publications between 2001 and 2010, was conducted in 2012. Two hundred sixty one articles were found and ordered according to the subject and type of publication. Thematic analysis of 37 articles on guidelines and recommendations for treatment of sexual problems is presented. Guidelines and recommendations published in the period from 2001 up to and including 2010 provides an overview of the discussion among professionals in the first decade of the 21st century. Six themes are analysed: (1) definitions of male and female dysfunctions, (2) prevalence…
The Influence of Retention, Turnover, and Alliance on Process and Outcomes in Rolling Group Psychotherapy for Cocaine Disorder
2016
ABSTRACTA longitudinal repeated measures design was used to investigate the influence of treatment retention, and membership turnover on individual outcomes, and the relationship between individual-level and group-level therapeutic alliance in rolling group psychotherapy for individuals with cocaine abuse disorder. Eighteen patients were studied; data were collected prior to therapy and then monthly for 24 months. Patient outcomes and process were assessed. Improvements in symptoms and psychological functioning were associated with retention in psychotherapy. Membership turnover had a negative influence on symptoms. Development of an individual alliance was affected by the development of gr…
Does higher technical efficiency induce a higher service level? A paradox association in the context of port operations
2020
Abstract Researchers and practitioners are benchmarking technical efficiency of ports and exploring the drivers of high efficiency. Paradoxically, this study argues that high technical efficiency (TE = 1) is not always essential, but an optimal level needs to be achieved while balancing the port service level. This study applies data envelopment analysis (DEA) and free disposal hull (FDH) methods to perform efficiency rankings of 38 container terminals from 17 different ports in 12 Asian countries. Four terminals are technically efficient (TE = 1) in all frontier approaches, thereof one Bangladeshi, one Chinese, one Indian and one Vietnamese. Furthermore, this study presents a case study co…
Novel Distance Estimation Methods Using 'Stochastic Learning on the Line' Strategies
2018
In this paper, we consider the problem of Distance Estimation (DE) when the inputs are the $x$ and $y$ coordinates (or equivalently, the latitudinal and longitudinal positions) of the points under consideration. The aim of the problem is to yield an accurate value for the real (road) distance between the points specified by the latter coordinates. 1 This problem has, typically, been tackled by utilizing parametric functions called the “Distance Estimation Functions” (DEFs). The parameters are learned from the training data (i.e., the true road distances) between a subset of the points under consideration. We propose to use Learning Automata (LA)-based strategies to solve the problem. In par…
Measuring foreland container port connectivity disaggregated by destination markets: An index for Short Sea Shipping services in Spanish ports
2020
Abstract The present research aims to develop a Foreland Port Connectivity Index (FPCI) including both qualitative and quantitative variables related to the characteristics of the maritime services provided. To that end, the FPCI incorporates two discount factors—the number of shipping services and destination countries—as penalties to correct for the quality of a port connection. After defining the FPCI, the index is applied to Spanish ports to study their connectivity in terms of container Short Sea Shipping (SSS) services. Although the connectivity of SSS traffic has not been widely studied, it is an interesting case study as small ports play a more relevant role in facilitating access t…
A more efficient cutting planes approach for the green vehicle routing problem with capacitated alternative fuel stations
2021
AbstractThe Green Vehicle Routing Problem with Capacitated Alternative Fuel Stations assumes that, at each station, the number of vehicles simultaneously refueling cannot exceed the number of available pumps. The state-of-the-art solution method, based on the generation of all feasible non-dominated paths, performs well only with up to 2 pumps. In fact, it needs cloning the paths between every pair of pumps. To overcome this issue, in this paper, we propose new path-based MILP models without cloning paths, for both the scenario with private stations (i.e., owned by the fleet manager) and that with public stations. Then, a more efficient cutting plane approach is designed for addressing both…
Branch-price-and-cut algorithms for the pickup and delivery problem with time windows and multiple stacks
2016
Abstract This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and multiple stacks. Each stack is rear-loaded and is operated in a last-in-first-out (LIFO) fashion, meaning that when an item is picked up, it is positioned at the rear of a stack. An item can only be delivered if it is in that position. This problem arises in the transportation of heavy or dangerous material where unnecessary handling should be avoided, such as in the transportation of cars between car dealers and the transportation of livestock from farms to slaughterhouses. To solve this problem, we propose two different branch-price-and-cut algorithms. The first sol…
