Introducing dynamism in emotional agent societies

[EN] This paper presents the development of a dynamic emotional model to be employed in agent societies. The proposed model is based on the PAD emotional model and allows the representation of the emotional contagion phenomena of a heterogeneous group of agents that are capable of express emotions. The model is mainly based on three elements: personality, empathy and affinity. These elements allow the characterisation of each individual, causing them susceptible to vary in some degree the emotions of other individuals. Additionally, the model allows defining of the social emotion of this group of agents. (C) 2017 Elsevier B.V.

ME3CA: A Cognitive Assistant for Physical Exercises that Monitors Emotions and the Environment

[EN] Recent studies show that the elderly population has increased considerably in European society in recent years. This fact has led the European Union and many countries to propose new policies for caring services directed to this group. The current trend is to promote the care of the elderly in their own homes, thus avoiding inverting resources on residences. With this in mind, there are now new solutions in this direction, which try to make use of the continuous advances in computer science. This paper tries to advance in this area by proposing the use of a personal assistant to help older people at home while carrying out their daily activities. The proposed personal assistant is called ME(3)CA, and can be described as a cognitive assistant that offers users a personalised exercise plan for their rehabilitation. The system consists of a sensorisation platform along with decision-making algorithms paired with emotion detection models. ME(3)CA detects the users' emotions, which are used in the decision-making process allowing for more precise suggestions and an accurate (and unbiased) knowledge about the users' opinion towards each exercise.This work was partly supported by the FCT-Fundacao para a Ciencia e Tecnologia through the Post-Doc scholarship SFRH/BPD/102696/2014 (A.

Objetivo. El propósito de este estudio fue identificar las enfermedades crónicas no mentales, más frecuentes en la población colombiana afectada por el conflicto armado. Metodología. Este es un estudio transversal, que usa datos de la Encuesta Nacional de Salud Mental 2015. La población estudiada se estratificó por sexo y edad y se extrajeron otros datos generales como: nivel educativo y grado de pobreza, medido por el Índice Multidimensional de Pobreza. Se analizaron datos de personas que reportaron haber sido víctimas del conflicto armado colombiano en algún momento de la vida la vida y se reportó como medida de riesgo relativo indirecto la frecuencia de presentación de enfermedades crónicas no mentales. Resultados. Se describió información de 10 764 personas mayores de 18 años siendo una muestra representativa a nivel nacional. Se encontró que 10,4 % de los sujetos afectados por el conflicto armado tienen un nivel educativo superior (técnico o universitario), así como 43,6 % se encuentran en estado de pobreza o en estado de vulnerabilidad. Las enfermedades crónicas no mentales identificadas fueron: hipertensión arterial 20,4 % (IC95% 15,7–26,1), diabetes 6,7 % (IC95% 4,4–10,3), enfermedades reumatológicas 10,4 % (IC95% 7,1–14,9), enfermedades gastrointestinales 19,1 % (IC95% 14,5–24,7), y dolor crónico 6,9 % (IC95% 4,2–11) Conclusiones. La población afectada por el conflicto armado tiene aparentemente mayor riesgo de presentar enfermedades crónicas no mentales, tales como hipertensión arterial y diabetes, lo que evidencia la situación de vulnerabilidad de estas comunidades.Q2Investigación original1-8Objective. The purpose of this study was to identify the most frequent non-mental chronic illnesses in the Colombian population affected by the armed conflict. Methodology. A cross-sectional study using data from the National Mental Health Survey 2015. The study population was stratified by sex and age and other general data were extracted, including education and poverty level, measured by the Multidimensional Poverty Index. Data analysis was based on information from people who reported having been victims of the Colombian armed conflict at some time in their lives; the frequency of presentation of non-mental chronic illnesses was reported as a measure of indirect relative risk. Results. Information on 10,764 people over 18 years of age was described, this being a representative sample at the national level. It was found that 10.4% of subjects affected by the armed conflict have a high educational level (technical school or university), and that 43.6% are living in conditions of poverty or vulnerability. The non-mental chronic illnesses identified were: hypertension 20.4% (CI95%: 15.7-26.1); diabetes 6.7% (CI95%: 4.4-10.3); rheumatologic diseases 10.4% (CI95%: 7.1-14.9); gastrointestinal diseases 19.1% (CI95%: 14.5-24.7); and chronic pain 6.9% (CI95%: 4.2-11) Conclusions. The population affected by the armed conflict is apparently at greater risk of presenting non-mental chronic illnesses such as hypertension and diabetes, which shows the vulnerability of these communities

Influencing over people with a social emotional model

[EN] This paper presents an approach of a social emotional model, which allows to extract the social emotion of a group of intelligent entities. The emotional model PAD allows to represent the emotion of an intelligent entity in 3-D space, allowing the representation of different emotional states. The social emotional model presented in this paper uses individual emotions of each one of the entities, which are represented in the emotional space PAD. Using a social emotional model within intelligent entities allows the creation of more real simulations, in which emotional states can influence decision-making. The result of this social emotional mode is represented by a series of examples, which are intended to represent a number of situations in which the emotions of each individual modify the emotion of the group. Moreover, the paper introduces an example which employs the proposed model in order to learn and predict future actions trying to influence in the social emotion of a group of people.This work is partially supported by the MINECO/FEDER TIN2015-65515-C4-1-R and the FPI grant AP2013-01276 awarded to Jaime-Andres Rincon.Rincon, J.; De La Prieta-Pintado, F.; Zanardini, D.; Julian Inglada, VJ.; Carrascosa Casamayor, C.

Competition between covalent bonding and charge transfer at complex-oxide interfaces

Here we study the electronic properties of cuprate/manganite interfaces. By means of atomic resolution electron microscopy and spectroscopy, we produce a subnanometer scale map of the transition metal oxidation state profile across the interface between the high $T_c$ superconductor YBa$_2$Cu$_3$O$_{7-\delta}$ and the colossal magnetoresistance compound (La,Ca)MnO$_3$. A net transfer of electrons from manganite to cuprate with a peculiar non-monotonic charge profile is observed. Model calculations rationalize the profile in terms of the competition between standard charge transfer tendencies (due to band mismatch), strong chemical bonding effects across the interface, and Cu substitution into the Mn lattice, with different characteristic length scales.Comment: 11+7 pages, 3+2 figure

Housing index, urbanisation level and lifetime prevalence of depressive and anxiety disorders : a cross-sectional analysis of the Colombian national mental health survey

Q2Q1Artículo originale019065Objectives To study socioeconomic inequalities in mental health in rural and urban Colombia, a country with a history of internal conflict and large socioeconomic inequalities. Recent survey data are available to study this understudied topic in a middle-income country. Methods Using data from 9656 respondents from the 2015 Colombian Mental Health survey, we investigated the association between lifetime prevalence of depressive and anxiety disorders and quality of dwellings and access to public services housing score (HS). We calculated the relative index of inequality (RII) and slope index of inequality (SII) for HS in urban and rural areas, adjusting for potential confounders and mediating factors. Outcomes The lifetime prevalence of anxiety and depression (combined) was 9.6% in urban versus 6.9% in rural areas (p<0.001). HS was not associated with prevalence of anxiety and depression in urban settings, whereas a higher HS (poorer housing quality) was associated with fewer mental disorders in rural areas in both univariate and multivariate models (multivariate RIIurban0.96 (95% CI 0.51 to 1.81); RIIrural0.11 (95% CI 0.04 to 0.32)). In rural areas, the prevalence of mental health problems was 12% points lower in persons living in the poorest quality dwellings than in those living in high-quality dwellings (SII −0.12 (95% CI −0.18 to −0.06)). Interestingly, within rural areas, persons living in ‘populated centres’ (small towns, villages) had a higher lifetime prevalence of any mental health disorder (9.8% (95% CI 6.9 to 13.6)) compared with those living in more isolated, dispersed areas (6.0% (95% CI 4.6 to 7.7)). Interpretation In rural Colombia, those living in the poorest houses and in dispersed areas had a lower prevalence of mental health problems. Further understanding of this phenomenon of a seemingly inverse association of prevalence of mental disorders with poverty and/or urbanisation in rural areas is needed. Particularly, considering the progressive urbanisation process in Colombia, it is important to monitor mental health in populations migrating to the cities

Serum angiopoietin-like 3 levels are elevated in obese non diabetic men but are unaffected during an oral glucose tolerance test

This study aimed to determine ANGPTL3 serum levels in healthy young lean and obese non-diabetic men during an oral glucose tolerance test (OGTT) and correlate them with anthropometric, biochemical and hormonal parameters. A case–control study was carried out and 30 young obese non-diabetic (23.90 ± 3.84 years and BMI 37.92 ± 4.85 kg/m2) and 28 age-matched healthy lean (24.56 ± 3.50 years and BMI of 22.10 ± 1.72 kg/m2) men were included in this study. The primary outcome measures were serum basal ANGPTL3 and ANGPTL3–area under the curve (AUC) levels. The percentage of body fat was measured by dual-energy X-ray absorptiometry and biochemical, hormonal and insulin resistance indices were determined. Basal ANGPTL3 and ANGPTL3–AUC levels were significantly elevated (p < 0.05) in young obese subjects compared with lean subjects and were positively and significantly associated with different anthropometric measurements. Fasting ANGPTL3 serum levels were positively correlated with fasting insulin, leptin, Leptin/Adiponectin index and triglyceride—glucose index. Moreover, ANGPTL3–AUC was negatively correlated with Matsuda index. In this regard, chronically high ANGPTL3 levels in young obese subjects might favor triglyceride-rich lipoprotein clearance to replenish triglyceride stores by white adipose tissue rather than oxidative tissues.Fil: Garcés, Maria Fernanda.

Carotid artery plaque in women with rheumatoid arthritis and low estimated cardiovascular disease risk: a cross-sectional study

INTRODUCTION: We previously reported that most patients with rheumatoid arthritis (RA) and moderate cardiovascular disease (CVD) risk according to the Systematic COronary Evaluation score (SCORE) experience carotid artery plaque. In this study, we aimed to identify patient characteristics that can potentially predict carotid plaque presence in women with RA and a concurrent low CVD risk according to the SCORE. METHODS: A cohort of 144 women with an evaluated low risk of CVD (SCORE value of zero) was assembled amongst 550 consecutive patients with RA that underwent CVD risk factor recording and carotid artery ultrasound. Participants had no established CVD, moderate or severe chronic kidney disease, or diabetes. We assessed carotid plaque(s) presence and its associated patient characteristics. RESULTS: Carotid artery plaque was present in 35 (24.3%) of women with RA. Age, the number of synthetic disease-modifying agents (DMARDs) and total cholesterol concentrations were independently associated with plaque in multivariable stepwise backward regression analysis (odds ratio (95% confidence interval)=1.15 (1.07 to 1.24), P49.5 years or/and total cholesterol concentration of >5.4 mmol/l, respectively, compared to only 7.8% in those (n=64; 44.4%) with age≤49.5 years or/and total cholesterol concentration of ≤5.4 mmol/l, respectively. CONCLUSIONS: Approximately one-third of women with RA who experience a low SCORE value and are aged >49.5 years or/and have a total cholesterol concentration of >5.4 mmol/l, experience high-risk atherosclerosis, which requires intensive CVD risk management
