Conditioned place preference: an animal model of motivational properties of drugs
2016
En el presente trabajo mostramos la técnica del condicionamiento de preferencia de lugar (CPL) como un modelo útil en el estudio de las propiedades motivacionales de las drogas. Se presentan los antecedentes de la técnica y se discuten algunas cuestiones metodológicas que es necesario considerar para diseñar una investigación empleando el modelo de CPL, como los diferentes tipos de aparatos disponibles, las diferentes fases del protocolo y sus posibles variaciones, el tipo de diseño (sesgado vs. no sesgado) o la necesidad de considerar los efectos del tiempo. Posteriormente se discuten algunas cuestiones a tener en cuenta a la hora de interpretar los datos obtenidos, como qué es lo que apre…
Condicionamiento de preferencia de lugar: un modelo animal para evaluar las propiedades motivacionales de las drogas (Conditioned place preference: a…
2016
This article investigated the Conditioned Place Preference (CPP) technique as a useful model for studying the motivational properties of drugs of abuse. The background of the technique is presented. Methodological issues that need to be considered when designing a study using CPP are discussed. These issues include the different types of apparatus available, the different phases of the protocol and its possible variations, the type of design (biased vs unbiased), and the need to consider time effects. We discuss data interpretation issues, such what the animal learns, the presentation of the dependent variable, the influence of novelty, state-dependent learning, latent inhibition, the motor…
Developing Tele-Operated Laboratories for Manufacturing Engineering Education
2010
The aim of the PeTEX-project is to establish an e-Learning platform for the development, implementation, and delivery of educational training programs in the field of manufacturing engineering. The PeTEX team designs both: a technical platform for eLearning based on “Moodle” including distributed tele-operated experimentation facilities, and didactic and socio-technical requirements for a successful online learning community. User interfaces are deployed for remote access to instruments, data analysis and multiplexed data access via network protocols. Hence, the platform provides complex tools in order to perform various activities to support the educational process, from telemetric experim…
Gap Filling of Biophysical Parameter Time Series with Multi-Output Gaussian Processes
2018
In this work we evaluate multi-output (MO) Gaussian Process (GP) models based on the linear model of coregionalization (LMC) for estimation of biophysical parameter variables under a gap filling setup. In particular, we focus on LAI and fAPAR over rice areas. We show how this problem cannot be solved with standard single-output (SO) GP models, and how the proposed MO-GP models are able to successfully predict these variables even in high missing data regimes, by implicitly performing an across-domain information transfer. CICYT TIN2015-64210-R In this work we evaluate multi-output (MO) Gaussian Process (GP) models based on the linear model of coregionalization (LMC) for estimation of biophy…
Anomaly and Change Detection in Remote Sensing Images
2021
Earth observation through satellite sensors, models and in situ measurements provides a way to monitor our planet with unprecedented spatial and temporal resolution. The amount and diversity of the data which is recorded and made available is ever-increasing. This data allows us to perform crop yield prediction, track land-use change such as deforestation, monitor and respond to natural disasters and predict and mitigate climate change. The last two decades have seen a large increase in the application of machine learning algorithms in Earth observation in order to make efficient use of the growing data-stream. Machine learning algorithms, however, are typically model agnostic and too flexi…
Análisis de técnicas de “aggregation”/“disaggregation” aplicadas a imágenes satélite para la estimación de parámetros térmicos superficiales a difere…
2023
Las aplicaciones que implican la observación de la superficie terrestre desde plataformas satélites a escala inferior a la regional, como por ejemplo, el caso del seguimiento de cultivos, requieren de una mayor disponibilidad de información térmica, en particular de la temperatura de la superficie terrestre (LST), con resoluciones espaciales apropiadas para un alcance local. Por ello, numerosos autores han propuesto y desarrollado métodos para extraer la LST a nivel “subpíxel”, mediante el empleo de productos complementarios de teledetección, con resultados adecuados para su uso en resoluciones superiores. La mayoría de estos métodos se basan en la correlación entre índices de vegetación, c…
Innovación en la gestión educativa: un estudio empírico
2021
ABSTRACT This paper analyzes the impact of innovative education tools-in this case, based on experimental methodology-on the acquisition of theoretical knowledge among management students. The study incorporates a clear split-sample design using two equivalent, randomly created groups. One group participates in a classroom experiment designed to illustrate the concept of the Phillips Curve, while the other participated in a traditional non-experimental lesson. The experiment is implemented under a strict protocol, while results evaluation is based on the comparison of post-experiment academic performance, which guarantees full anonymity and privacy of decisions. This design analyzes the imp…
Data from: Learning outdoors: Male lizards show flexible spatial learning under semi-natural conditions
2013
Spatial cognition is predicted to be a fundamental component of fitness in many lizard species, and yet some studies suggest that it is relatively slow and inflexible. However, such claims are based on work conducted using experimental designs or in artificial contexts that may underestimate their cognitive abilities. We used a biologically realistic experimental procedure (using simulated predatory attacks) to study spatial learning and its flexibility in the lizard Eulamprus quoyii in semi-natural outdoor enclosures under similar conditions to those experienced by lizards in the wild. To evaluate the flexibility of spatial learning, we conducted a reversal spatial-learning task in which p…
Research on Service-Learning in Physical Activity and Sport: Where We Have Been, Where We Are, Where We Are Going
2022
Higher education is under constant transformation through the use of new pedagogical models such as university service-learning (SL). Indeed, there has been an exponential uptake of university SL, among others, in the field of physical activity and sport (PAS) along with research examining these practices. However, these initiatives highlight the need to improve the quality of research in this field. This paper presents a systematic review focused on how research in this arena has been carried out, examining the following topics: paradigm, methods, instruments, discipline, limitations, and further research. A total of 45 articles met the inclusion criteria. The results show that qualitative…

2016
The aim of this ethnographic and autoethnographic research was to explore what kind of a learning culture existed in an 8th grade English class in a Finnish basic education school in the 2011-2012 academic year. The class was taught jointly by a subject teacher and a special education teacher. A teaching experiment was implemented with the support of co-teaching during which teachers aimed to strengthen students' learning autonomy: to support their active learning and help them act as responsible learners. The research data included participant observation notes, interviews of a subject teacher and students, and different kinds of documents produced by teachers and students during the imple…
