A duration model analysis of consumer preferences and determinants of video game consumption

Despite the enormous revenues generated by the video game industry in recent years, relatively little research has been undertaken into consumer preferences and the determinants of video game consumption. This study addresses this deficiency through the analysis of data from a popular online video game that includes historic behavioural information for 1,408 consumers participating in 728,811 unique rounds of gameplay. We analyse these data with the goal of estimating determinants of the aggregate amount of time that a consumer spends playing the game. Through the estimation of duration models, we show that less experienced consumers are less likely to continue playing the game at any given point, possibly due to having achieved mastery and becoming bored. However, we also find that consumers tend to play the game for longer periods when using a wider range of character roles and vehicles, implying that a consumer's interest can be maintained through exposure to greater variety. Our results represent the first such evidence on in-game consumer preferences, which has important implications for video game consumption through optimisation of gameplay experiences to satisfy these preferences

Las redes sociales como instrumento de gestión de destinos turísticos

The main objective of this research focuses on determining the functions and application of social networks in the management of tourist destinations, with the aim of revealing the state of the art and degree of applicability. First, in order to fulfill the objectives and theoretical hypotheses, a bibliographic analysis is carried out, which leads to the elaboration of the state of the art regarding the topic on which this doctoral thesis revolves. In this sense, the state of the art of the research is elaborated from a systematic analysis of the scientific literature on smart destinations (concept, dimensions, components, management systems) and their integration with social networks. In order to respond to the second group of specific objectives and hypotheses, the methodology applied was quantitative, based on the analysis of a series of data from Spanish tourist destinations in terms of their presence and management of social networks. The quantification of these variables, for each of the 78 tourist destinations (among which were all the smart tourist destinations, hosted by the SEGITTUR project), allowed us to apply different quantitative statistical techniques, such as: a) Pearson's correlation analysis, to establish the type of interrelation between the independent variable (number of visitors) and the dependent variables, which referred to the presence and management of the destinations on the web and in social networks; and b) to determine the degree of use of social networks by the smart destinations with respect to the others, an ANOVA analysis was carried out between the variables of the most visited destinations with respect to those of the smart destinations, in order to detect possible statistically significant differences between the two groups of destinations with respect to their management of social networks. Finally, in order to fulfill the third group of objectives and specific hypotheses, and to demonstrate whether there is complementarity between the data provided by social networks and those offered by official statistics, in terms of tourism demand, a qualitative methodology is followed, since it is based on an exploratory case analysis. In this sense, the change experienced by the behaviors and feelings of tourists visiting Andalusia as a result of COVID-19 is analyzed, both with data from the Andalusia Tourism Situation Survey (ECTA, 2020) and by means of a sentiment analysis using Twitter data. For the exploratory sentiment analysis, using Twitter, the statistical program R and the library package (rtweet) were used to retrieve messages from the social network Twitter (tweets). Machine learning sentiment analysis algorithms were then applied to the resulting data. Therefore, based on the results obtained from this doctoral thesis, we believe that it is necessary for tourist destinations to have a professional specialized in the management of social networks (social media manager), as this will allow the destination to make the most of its presence in social networks. In short, it is considered that research focused on the applicability of social networks to the management processes of tourist destinations is still in its early stages of development, especially if we analyze the real applicability it is having in specific tourist destinations. This recommendation is important both when it comes to adapting to the progressive development of new technologies, as well as to the evolution of the behavior and profile of tourists, who are increasingly familiar with the use of new technologies, and demand flexible experiences adapted to their preferences, among other characteristics.El objetivo principal de esta investigación se centra en determinar las funciones y aplicación de las redes sociales en la gestión de los destinos turísticos, con objeto de poner de manifiesto el estado de la cuestión y grado de aplicabilidad. Primero para dar cumplimiento a los objetivos e hipótesis teóricas, se realiza un análisis bibliográfico, el cual da lugar a la elaboración del estado del arte respecto al tema sobre el que gira la presente tesis doctoral. En este sentido, el estado del arte de la investigación se elabora a partir de un análisis sistemático de la literatura científica acerca de los destinos turísticos inteligentes (concepto, dimensiones, componentes, sistemas de gestión) y su integración con las redes sociales. Para dar respuesta al segundo grupo de objetivos e hipótesis específicas, la metodología aplicada fue de tipo cuantitativa, basada en el análisis de una serie de datos que arrojan los destinos turísticos españoles en cuanto a su presencia y gestión de las redes sociales. La cuantificación de estas variables, para cada uno de los 78 destinos turísticos (entre los que se encontraban todos los destinos turísticos inteligentes, acogidos al proyecto de SEGITTUR), nos permitió aplicar diferentes técnicas estadísticas cuantitativas, tales como: a) el análisis de correlación de Pearson, para establecer el tipo de interrelación entre la variable independiente (número de visitantes) y las variables dependientes, que se referían a la presencia y gestión de los destinos la web y en las redes sociales; y b) para determinar el grado de utilización de las redes sociales por parte de los destinos turísticos inteligentes respecto a los restantes, se realizó un análisis ANOVA entre las variables de los destinos más visitados respecto a las de los destinos turísticos inteligentes, con objeto de detectar posibles diferencias estadísticamente significativas entre ambos grupos de destinos en lo que respecta a la gestión que hacen de las redes sociales. Por último, para dar cumplimiento al tercer grupo de objetivos e hipótesis específicas, y demostrar si existe complementariedad entre los datos que arrojan las redes sociales y los que ofrecen las estadísticas oficiales, en lo que respecta a la demanda turística, se sigue una metodología de corte cualitativa, ya que se fundamenta en un análisis de caso, de carácter exploratorio. En este sentido, se analiza el cambio experimentado por los comportamientos y sentimientos de los turistas que visitan Andalucía como consecuencia de la COVID-19, tanto con los datos de la Encuesta de Coyuntura Turística de Andalucía (ECTA, 2020) como mediante un análisis de sentimientos con datos de Twitter. Para el análisis exploratorio de sentimientos, mediante Twitter, se utilizó el programa estadístico R y el paquete de biblioteca (rtweet) para la recuperación de mensajes de la red social Twitter (tweets). A continuación, se aplicaron algoritmos de análisis de sentimientos mediante aprendizaje automático a los datos resultantes. Por todo ello, a partir de los resultados que se obtienen de esta tesis doctoral, consideramos que se hace necesario que los destinos turísticos cuenten con un profesional, especializado en la gestión de redes sociales (social media manager), pues ello permitirá al destino sacar el máximo provecho a su presencia en las redes sociales. No en vano, esta actuación posibilitará el máximo desempeño de las múltiples funciones que, a lo largo de la investigación, se han puesto de manifiesto, que pueden desempeñar esta herramienta, dentro de los procesos de gestión de los destinos turísticos En definitiva, se considera que la investigación centrada en la aplicabilidad de las redes sociales a los procesos de gestión de los destinos turísticos está aún en sus primeras etapas de desarrollo, sobre todo si analizamos la aplicabilidad real que está teniendo en destinos turísticos concretos. Esta recomendación es importante tanto a la hora de adaptarse al progresivo desarrollo de las nuevas tecnologías, como por la evolución que viene experimentando el comportamiento y perfil de los turistas, los cuales, cada vez, están más familiarizados con el uso de nuevas tecnologías, y demandan experiencias flexibles y adaptadas a sus preferencias, entre otras características

Variety in the video game industry:an empirical study of the Wundt curve

This study analyzes the effect of variety on consumer utility using historical behavioral information for 1,397 consumers participating in 729,049 unique rounds of play. We show that consumers generally exhibit a preference for variety as part of their gameplay utility. The relationship between variety and utility is nonlinear and follows, at least for some types of variety, an inverted u-shape as predicted by the Wundt curve. Our results represent the first such evidence on the importance of variety in video gaming, which has significant implications for consumption through optimization of gameplay utility to satisfy the demand for variety.</p

eHealth Conversations : using information management, dialogue, and knowledge exchange to move toward universal

The publication of eHealth Conversations, developed with the support of the Spanish Agency for International Development Cooperation (AECID), represents a major step forward for the PAHO/WHO Strategy, since it explores ways of implementing regional mechanisms with free and equitable access to information and knowledge sharing. These initiatives aim to advance the goals of more informed, equitable, competitive, and democratic societies, where access to health information is considered a basic right. This publication is one of the instruments used by PAHO/WHO to develop the initiatives outlined in the Strategy, which coincides with the global eHealth strategy. One of the fundamental needs for the improvement of eHealth is the dissemination of information, and PAHO/WHO is assuming a leading role in this effort. The development of this new electronic publication is a key step in disseminating information that will be useful for decision makers on applying these technologies for the health of the Americas. This electronic book is one of the products of PAHO/WHO’s project: “eHealth Conversations: Using Information Management, Dialogue, and Knowledge Exchange to Move Toward Universal Access to Health.” Participants in these conversations included experts on electronic health and other specialties. Through virtual dialogues, the experts contributed with knowledge and reflections on the present and the future of eHealth in the Americas, analyzed the situation, and made recommendations for the implementation of electronic health initiatives. These recommendations are not only intended for PAHO/ WHO, but also for governments and the private sector. The aim of the project is to guarantee the convergence of local, national, and regional initiatives regarding the adoption and application of ICTs for public health, with special attention on critical issues in this field. It also intends to strengthen individual and collective capacities of health workers and institutions, connecting them in a network of on-line health networks, as well as to reinforce the PAHO/WHO eHealth program.Acknowledge the Spanish Agency for International Development Cooperation (AECID) for its financial support in preparing this publication and developing the project titled “eHealth Conversations: Using Information Management, Dialogue, and Knowledge Exchange to Move Toward Universal Access to Health;

Exploring attributes, sequences, and time in Recommender Systems: From classical to Point-of-Interest recommendation

Tesis Doctoral inédita leída en la Universidad Autónoma de Madrid, Escuela Politécnica Superior, Departamento de Ingenieria Informática. Fecha de lectura: 08-07-2021Since the emergence of the Internet and the spread of digital communications throughout the world, the amount of data stored on the Web has been growing exponentially. In this new digital era, a large number of companies have emerged with the purpose of ltering the information available on the web and provide users with interesting items. The algorithms and models used to recommend these items are called Recommender Systems. These systems are applied to a large number of domains, from music, books, or movies to dating or Point-of-Interest (POI), which is an increasingly popular domain where users receive recommendations of di erent places when they arrive to a city. In this thesis, we focus on exploiting the use of contextual information, especially temporal and sequential data, and apply it in novel ways in both traditional and Point-of-Interest recommendation. We believe that this type of information can be used not only for creating new recommendation models but also for developing new metrics for analyzing the quality of these recommendations. In one of our rst contributions we propose di erent metrics, some of them derived from previously existing frameworks, using this contextual information. Besides, we also propose an intuitive algorithm that is able to provide recommendations to a target user by exploiting the last common interactions with other similar users of the system. At the same time, we conduct a comprehensive review of the algorithms that have been proposed in the area of POI recommendation between 2011 and 2019, identifying the common characteristics and methodologies used. Once this classi cation of the algorithms proposed to date is completed, we design a mechanism to recommend complete routes (not only independent POIs) to users, making use of reranking techniques. In addition, due to the great di culty of making recommendations in the POI domain, we propose the use of data aggregation techniques to use information from di erent cities to generate POI recommendations in a given target city. In the experimental work we present our approaches on di erent datasets belonging to both classical and POI recommendation. The results obtained in these experiments con rm the usefulness of our recommendation proposals, in terms of ranking accuracy and other dimensions like novelty, diversity, and coverage, and the appropriateness of our metrics for analyzing temporal information and biases in the recommendations producedDesde la aparici on de Internet y la difusi on de las redes de comunicaciones en todo el mundo, la cantidad de datos almacenados en la red ha crecido exponencialmente. En esta nueva era digital, han surgido un gran n umero de empresas con el objetivo de ltrar la informaci on disponible en la red y ofrecer a los usuarios art culos interesantes. Los algoritmos y modelos utilizados para recomendar estos art culos reciben el nombre de Sistemas de Recomendaci on. Estos sistemas se aplican a un gran n umero de dominios, desde m usica, libros o pel culas hasta las citas o los Puntos de Inter es (POIs, en ingl es), un dominio cada vez m as popular en el que los usuarios reciben recomendaciones de diferentes lugares cuando llegan a una ciudad. En esta tesis, nos centramos en explotar el uso de la informaci on contextual, especialmente los datos temporales y secuenciales, y aplicarla de forma novedosa tanto en la recomendaci on cl asica como en la recomendaci on de POIs. Creemos que este tipo de informaci on puede utilizarse no s olo para crear nuevos modelos de recomendaci on, sino tambi en para desarrollar nuevas m etricas para analizar la calidad de estas recomendaciones. En una de nuestras primeras contribuciones proponemos diferentes m etricas, algunas derivadas de formulaciones previamente existentes, utilizando esta informaci on contextual. Adem as, proponemos un algoritmo intuitivo que es capaz de proporcionar recomendaciones a un usuario objetivo explotando las ultimas interacciones comunes con otros usuarios similares del sistema. Al mismo tiempo, realizamos una revisi on exhaustiva de los algoritmos que se han propuesto en el a mbito de la recomendaci o n de POIs entre 2011 y 2019, identi cando las caracter sticas comunes y las metodolog as utilizadas. Una vez realizada esta clasi caci on de los algoritmos propuestos hasta la fecha, dise~namos un mecanismo para recomendar rutas completas (no s olo POIs independientes) a los usuarios, haciendo uso de t ecnicas de reranking. Adem as, debido a la gran di cultad de realizar recomendaciones en el ambito de los POIs, proponemos el uso de t ecnicas de agregaci on de datos para utilizar la informaci on de diferentes ciudades y generar recomendaciones de POIs en una determinada ciudad objetivo. En el trabajo experimental presentamos nuestros m etodos en diferentes conjuntos de datos tanto de recomendaci on cl asica como de POIs. Los resultados obtenidos en estos experimentos con rman la utilidad de nuestras propuestas de recomendaci on en t erminos de precisi on de ranking y de otras dimensiones como la novedad, la diversidad y la cobertura, y c omo de apropiadas son nuestras m etricas para analizar la informaci on temporal y los sesgos en las recomendaciones producida
