Partisanship, Ideology, and Selective Exposure: A Longitudinal Analysis of Media Consumption in Spain (2008–2019)
2022
La literatura sobre exposición selectiva ha demostrado que la ideología y el voto gobiernan las decisiones de consumo de medios, pero los estudios longitudinales aún son escasos. Para llenar este vacío, este trabajo analiza: (a) si la exposición selectiva guiada por la ideología y el partidismo a tres tipos de medios (televisión, radio y periódicos) es un fenómeno estable en España (2008-2019) como se espera de un medio pluralista polarizado. sistema; y (b) qué variable tiene los efectos más fuertes en las elecciones de noticias (ideología o partidismo). Se realizan regresiones logísticas multinomiales utilizando fuentes de datos de seis encuestas postelectorales realizadas por el Centro de…
An optimization approach for communal home meal delivery service
2009
Abstract: This paper is the first to discuss the communal home meal delivery problem. The problem can be modelled as a multiple travelling salesman problem with time windows, that is closely related to the well-studied vehicle routing problem with time windows. Experimental results are reported for a real-life case study from Central Finland over several alternative scenarios using the SPIDER commercial solver. The comparison with current practice reveals that a significant savings potential can be obtained using off-the-shelf optimization tools. As such, the potential for supporting real-life communal routing problems can be considered to be important for VRP practitioners.
Análisis de aguas residuales con fines epidemiológicos: aplicaciones a la estimación del consumo de sustancias de abuso y en salud pública en general…
2018
[ES] En este artículo se presenta la metodología de análisis de aguas residuales con fines epidemiológicos (wastewater-based epidemiology, WBE) y su potencial para abordar diversos aspectos relacionados con la salud pública. Esta metodología permite obtener datos a una escala temporal y espacial relativamente pequeña (típicamente datos diarios-semanales sobre un municipio) de hábitos de consumo de sustancias de abuso, ilegales (como la cocaína o el cannabis) o legales (como el alcohol) a través de la determinación de biomarcadores de consumo (el compuesto original no metabolizado o alguno de sus metabolitos) en el agua residual. Aparte de discutir los fundamentos, ventajas y limitaciones de…
COLLABORATIVE ECONOMY AS AN INDICATION OF SUSTAINABLE CONSUMPTION IN RESULTS OF EXAMINED PEOPLE
2017
Sustainable consumption takes inspiration from the newest trends in economics which is a collaborative economy. This type of economy changes the model of organization and distribution based on sharing, using and creating together. The basic aim of this study is pointing out a purpose of a collaborating economy in the accomplishment of sustained consumption rules and in a conscious and self-motivated limit of personal consumption to the purpose of co-sharing. This task is going to be achieved with empirical verification of consumers behavior based on answers to a questionnaire. Research has confirmed the suggested hypothesis. People want to attend in collaborative consumption, which is posit…
Electricity Consumption Analysis of Tertiary Buildings: An Empirical Approach for Two University Campuses
2020
An empirical approach for the analysis of energy consumption of existing buildings of the tertiary sector is presented in this study. It allowed the organization and management of large amounts of data according to different timeframes and helped to focus on leading issues about energy uses, and dealt with compatibility with tariff structure. The analysis method, which implied a powerful graphical representation of the results, allowed us to detect critical issues in electricity energy management for public buildings and improve their energy performance. Furthermore, the authors proposed a set of electricity consumption indexes (ECIs) that gave useful insight into the main hotspots. The bas…
Analysis of the appropriation of a connected object : an experiential and dimensional approach
2022
The evolution and interactivity of connected objects promise a continuous improvement of the consumer experience, especially through the adaptation of the object and the development of its functionalities. But in some cases, the evolving nature of the object can lead to a situation where the user has to reappropriate it. Through a netnography and an analysis of life stories, this research studies the appropriation process in a dynamic way.The main contribution of this research is the identification of two dimensions (social and situational) and four forms of appropriation : autotelic, instrumental, individual and collective, which we bring closer to Lanier and Rader's (2015) measure of expe…
Wine and Women: A Focus on Feminine Consumption of Wine
2014
Continuous evolution of modern society provides changes in lifestyle and consumption habits, consequently reflecting on food consumption, where we can include the wine. In this context, even for wine there have been changes from the past to today, driving more and more consumers to think about this product less and less as a beverage and an more as a hedonistic and refined product. Relationship with wine changed also at generational and social level and women become interested and passionate consumers, aware of its quality; often also with a great role in the wine world choosing jobs like wine-sellers, producers, sommeliers or oenologist. Wine by the feminine side means the pleasure of enjo…
Future Development of an Energy-Efficient Electric Scooter Sharing System Based on a Stakeholder Analysis Method
2023
E-scooters as a new form of mobility are gaining more and more popularity. This popularity results from the flexibility of this mode of transport, but above all from the positive impact on the natural environment through the much higher energy efficiency of an e-scooter compared to a motor vehicle (according to the literature the rate is 2 km per kWh equivalent for a motor vehicle and the range is 90–100 km per kWh in the case of an e-scooter). This paper introduces a discussion on the future development of an energy-efficient electric scooter sharing system based on stakeholder analysis methods. The implementation of the e-scooter sharing system involves linking several areas of human acti…
Counselling toward reducing alcohol use, knowledge about its morbidity and personal consumption among students of medical and dental courses in north…
2021
Background Alcohol use disorder (AUD) is directly linked to high-risk consumption. Healthcare students have a crucial role to play in its prevention and management. The aim of this study is to analyse alcohol consumption, as well as to consider the knowledge and attitudes regarding morbidity, and the stage of change when providing assistance to quit AUD. Material and Methods A cross-sectional study was conducted among Dentistry and Medical students using specific and validated questionnaires in an anonymous and voluntary way. Initially, 925 students were invited to participate, of them 500 were reached. Results Among them 85.9% suffered from AUD of whom 75% were women (p<0.001), and it was …
