¿Movilidad inclusiva o accesibilidad inclusiva?
2017
<p>“La movilidad inclusiva” es parte de las prioridades políticas definidas por numerosos países europeos para referirse a la dimensión social del transporte o las políticas de movilidad cotidiana. De forma general, la inclusión se refiere a la cohesión social, que ha sido uno de los objetivos declarados de la Unión Europea desde el inicio de los años 2000. Como mecanismo para facilitar el acceso a las oportunidades (empleo, comercio, servicios, etc.), la movilidad individual es actualmente considerada un prerrequisito necesario para la participación de las personas en las actividades sociales. En contraste, la inmovilidad o “ausencia de movilidad” sería un factor de exclusión social.…
La consagración de los derechos fundamentales: de principios generales a texto fundacional de la Unión Europea
2014
<p>El autor argumenta que el reconocimiento formal de los derechos fundamentales como parte de los fundamentos comunes de la UE mediante la remisión a la Carta de los Derechos Fundamentales en el Tratado de Lisboa (otorgándole carácter vinculante y, por ende, elevando su rango y confiriéndole el mismo valor jurídico que los Tratados) ha proporcionado una mayor apariencia constitucional a la UE, pero no un nivel más generoso de protección y de disfrute de la ciudadanía. En efecto, además de haber prescindido de garantías específicas, la Carta de la UE ha introducido diversas asimetrías inaceptables, tales como la quiebra del principio de indivisibilidad (los derechos civiles y los soci…
Socio-spatial differentiation in transition: a preliminary comparative analysis of post-soviet St Petersburg and Riga
2020
Research into the socio-spatial dynamics in Central European cities is an important area of contemporary transition studies. Open issues in this domain range from defining a theoretical framework to data availability and methodological approaches. As to the former aspect, recent literature focuses on the hybrid nature of the post-socialist urban space, which underwent modernization in the conditions of globalization and economic liberalization; the earlier model of spatial development changed dramatically as a result. The multi-scalar and comparative approaches may shed new light on the complex patterns of urban socio-spatial differentiation and its post-Soviet dynamics. Growing regional so…
Migrant Friendships in a Super-Diverse City. Russian-Speakers and their Social Relationships in London in the 21st Century
2017
The book is built on excellent premises which include a super-diverse city, a highly heterogeneous migrant population, as well as a post-Soviet cultural background which embeds two opposed tendenci...
Digital Banking in Northern India: The Risks on Customer Satisfaction
2021
The widespread use of digital technologies and the current pandemic (COVID) have fueled the need and call for digital transformation in the banking sector. Although this has various benefits, it is a disruption to the norm to which a bank customer has to become accustomed. This variance means that customers would have to make some changes to their routine. This can constitute risks in terms of maintaining customer satisfaction at previous levels. These risks are associated with customer retention because a service or product needs to be aligned with customer expectations to avoid them switching to other service providers. Moreover, it can also have an effect on reputa- tion. Offering digita…
Ein Ansatz zur Erklärung der Kundenbindung auf Basis der Theorie des geplanten Verhaltens
2005
Traditional customer satisfaction and customer retention models are extended by integrating variables such as perceived action control or social norm. These constructs are suggested by the attitude theory as well as the theory of planned behaviour. The extended model is tested in an empirical study carried out in the movie theatre industry. The model provides an excellent explanation of customer retention, which is the target variable in the study. Implications are derived for satisfaction managers which focus on the social group when approaching a specific customer. Finally, an outline for further theoretical and empirical studies is given as well as some limitations of the proposed model.
Observations on the Progress of Welfare-State Construction in Hungary, Poland, and the Czech Republic
2003
Three specialists in social services present an assessment of Hungary's performance during the economic transition from the perspective of social policy and the general welfare of the population. Using figures drawn from a variety of European sources, they offer a review of social expenditure, labor market tendencies, and the social security, health and education systems, comparing throughout with data from the Czech Republic, Poland and the European Union.
Morphological similarities between DBM and a microeconomic model of sprawl
2010
JEL classification : C61; C63; D62; R21; R40; International audience; We present a model that simulates the growth of a metropolitan area on a 2D lattice. The model is dynamic and based on microeconomics. Households show preferences for nearby open spaces and neighbourhood density. They compete on the land market. They travel along a road network to access the CBD. A planner ensures the connectedness and maintenance of the road network. The spatial pattern of houses, green spaces and road network self-organises, emerging from agents individualistic decisions. We perform several simulations and vary residential preferences. Our results show morphologies and transition phases that are similar…
Data Augmentation Approach in Bayesian Modelling of Presence-only Data
2011
Abstract Ecologists are interested in prediction of potential distribution of species in suitable areas, essential for planning conservation and management strategies. Unfortunately, often the only available information in such studies is the true presence of the species at few locations of the study area and the associated environmental covariates over the entire area, referred as presence-only data. We propose a Bayesian approach to estimate logistic linear regressions adapted to presence-only data through the introduction of a random approximation of the correction factor in the adjusted logistic model that allows us to overcome the need to know a priori the prevalence of the species.
What is the best fitting function? Evaluation of lactate curves with common methods from the literature
2015
Using the lactate threshold for training prescription is the gold-standard, although there are several open questions. One open question is: What is the best fitting method for the load-lactate data points? This investigation re-analyses over 3500 lactate diagnostic datasets in swimming. Our evaluation software examines six different fitting methods with two different minimization criteria (RMSE and SE). Optimization of parameters of the functions is put in excecution with gradient descent. From a mathematical point of view, the double phase model, which consists of two linear regression lines, shows the least errors (RMSE min 0.254 ± 0.172; SE min 0.311 ± 0.210). However, this method canno…
