Socioeconomic inequality in the use of long-term care among European older adults: an empirical approach using the SHARE survey

The increase in the proportion of elderly people in developed societies has several consequences, such as the rise in demand for long-term care (LTC). Due to cost, inequalities may arise and punish low-income households. Our objective is to examine socioeconomic inequalities in LTC utilization in Europe. We use the last wave from the Survey of Health, Aging, and Retirement in Europe SHARE (Munich Center for the Economics of Ageing, Munich, Germany), dated 2017, to analyze the impact of socioeconomic status (SES) on LTC. For this purpose, we construct logistic models and control for socioeconomic/household characteristics, health status, and region. Then, concentration indices are calculated to assess the distribution of LTC. Moreover, we also analyze horizontal inequity by using the indirect need-standardization process. We use two measures of SES (household net total income and household net wealth) to obtain robust results. Our findings demonstrate that informal care is concentrated among low-SES households, whereas formal care is concentrated in high-SES households. The results for horizontal concentration indices show a pro-rich distribution in both formal and informal LTC. We add new empirical evidence by showing the dawning of deep social inequalities in LTC utilization. Policymakers should implement policies focused on people who need care to tackle socioeconomic inequalities in LTC.Acknowledgments: This paper used data from SHARE Wave 7 (DOIs: 10.6103/SHARE.w7.700); see [50] for methodological details.

Emoterapia

Treball Final de Grau en Comunicació Audiovisual. Codi: Curs: 2013/2014Emoterapia es un cortometraje de ficción que se ha realizado para sensibilizar a la sociedad de las consecuencias negativas de las nuevas tecnologías (TIC) en las relaciones interpersonales. Su finalidad es múltiple: criticar la necesidad del uso constante de las TIC, concienciar a la sociedad de sus efectos nocivos y denunciar el doble rasero existente respecto a dicho tema. Mediante una idea y su posterior desarrollo en guión, el proyecto fue creciendo hasta convertirse en una obra audiovisual en la que se criticaba abiertamente la adicción a las TICs en general y al WhatsApp en particular por parte de un gran estrato de la sociedad. Esta pequeña investigación, a la que apunta -como demanda- el cortometraje en tono de comedia, es vital para poder mejorar como sociedad y continuar avanzando hacia el futuro, en una época en la que las TICs dominan el panorama comunicativo.Emoterapia is a fiction short film, which has been created to heighten the awareness in society about the negative consequences of the new technologies (ITCs) in the interpersonal relationships. Its finality is multiple: critic the need of constant use of ITCs, concienciate the society about its bad effects and denounce the double standard existing about this topic. Thanks to an idea and its later development into a screenplay, the project was rounded out until it became an audiovisual project where the ITCs addition in general and to WhatsApp in particular by a wide part of the society are openly critiqued. This small research, pointed to –as it is required- the short film in a humorous tone, is vital to be able to improve as a society and to continue moving forwards towards the future, in period in ITCs dominate the communicative world

Asthma and Rhinitis in South America: How Different They are From Other Parts of the World.

Asthma and rhinitis epidemiology has wide variations around the world. The aim of this review was verify the prevalence of asthma and rhinitis in South America and report differences from other regions of the world. We reviewed studies with International Study of Asthma and Allergies in Childhood (ISAAC) methodology in South America, Phases I and III. In South America the ISAAC Phase I ranked four countries among top ten in prevalence of asthma and three countries among top ten in prevalence of rhinoconjunctivitis. ISAAC Phase III showed little changes in asthma and rhinitis prevalence in South American countries. The prevalence increases of asthma and rhinitis in South American centers indicate that the burden of both is continuing to rise, but the differences in prevalence are lessening.Revisión por pare

Study of a hybrid OCDMA-WDM segmented ring for metropolitan area networks

Proceeding of: 12th International Conference on High Performance Switching and Routing, Cartagena, Spain, July 4-6, 2011Optical Code Division Multiple Access (OCDMA) techniques have shown outstanding capabilities in the sharing of optical media, in particular in access networks. However, OCDMA systems may suffer from Multiple Access Interference (MAI) and other kinds of noise when many users access the shared media simultaneously, increasing the BER (Binary Error Rate) to unacceptable levels, that is, a situation at which all combined signals interfere and are lost. This work proposes a mixed OCDMA and Tunable Transmitter- Fixed Receiver (TT-FR) WDM and ring architecture at which the ring is split into small-size segments to limit the probability of MAI. Essentially, every segment in the ring has got two hub nodes (on the segment’s head and tail) which forwards inter-segment traffic to other hub nodes on dedicated home wavelengths, thus making use of WDM. The access media inside the segment is shared between the nodes by means of OCDMA, and code reuse is possible on different segments. Our performance analysis shows how to split a given ring into segments in order to minimise the BER due to multiple users accessing the network and allow for high bit-rates for a given traffic load. In addition, we analyse the possibility of introducing Forward Error Correction (FEC) at a moderate overhead cost to improve performance.The work described in this paper was carried out with the support of the BONE project (“Building the Future Optical Network in Europe”), a Network of Excellence funded by the European Commission through the 7th ICT-Framework Programme.

A CTMC-based characterisation of the propagation of errors in GMPLS Optical Rings

Abstract: This article presents a Continuous-Time Markov Chain model to characterise the propagation of failures in optical GMPLS rings. In order to characterize the behaviour of failure propagation epidemic-based models are commonly used. However, the existing epidemic models do not take into account the specific features of a multilayer network environment. A node failure in GMPLS-based networks can affect: Control Plane and Data plane reporting different failures scenarios. Consequently, an extended generic epidemic model called SID is proposed, in order to cover multiple failures and recovered states in a GMPLS Multilayer scenario. The CTMC model takes into account the SID model and provides a set of design rules to specify the values of repair rates required to achieve a given service availability, assuming a certain infection and disable rate.The work described in this paper was carried out with the support of the BONE project (''Building the Future Optical Network in Europe''), a Network of Excellence funded by the European Commission through the 7th ICT-Framework Programme.

Failure propagation in GMPLS optical rings: CTMC model and performance analysis

Network reliability and resilience has become a key design parameter for network operators and Internet service providers. These often seek ways to have their networks fully operational for at least 99.999% of the time, regardless of the number and type of failures that may occur in their networks. This article presents a continuous-time Markov chain model to characterise the propagation of failures in optical GMPLS rings. Two types of failures are considered depending on whether they affect only the control plane, or both the control and data planes of the node. Additionally, it is assumed that control failures propagate along the ring infecting neighbouring nodes, as stated by the Susceptible-Infected-Disabled (SID) propagation model taken from epidemic-based propagation models. A few numerical examples are performed to demonstrate that the CTMC model provides a set of guidelines for selecting the appropriate repair rates in order to attain specific availability requirements, both in the control plane and the data plane.This work is partially supported by the Spanish Ministry of Science and Innovation project TEC 2009-10724 and by the Generalitat de Catalunya research support programme (SGR-1202).

Socioeconomic determinants and health care utilization among elderly people living in Europe: Evidence from the Survey of Health, Ageing and Retirement.

This paper examines health care utilization among elderly people in sixteen European countries using the last wave of the Survey of Health, Ageing and Retirement in Europe (SHARE). Negative Binominal regression is conducted to study the main driving factors behind health care utilization (visits to the General Practitioners, GP; Hospital Stays, HS). The empirical results suggest that age, gender, education level, self-assessed health, health limitations and status and other socioeconomic variables are the main driving factors. We also show that socioeconomic variables do not play the same role in every country. From a policy economic approach, we propose important information to the current debates both in the health economics and social welfare literature. Our findings are relevant and have several implications for policy purposes to enhance efficiency, equity and quality of health care that it can be provided
