Differences of Functional Connectivity Brain Network in Emotional Judgment

Using combined emotional stimuli, combining photos of faces and recording of voices, we investigated the neural dynamics of emotional judgment using scalp EEG recordings. Stimuli could be either combioned in a congruent, or a non-congruent way.. As many evidences show the major role of alpha in emotional processing, the alpha band was subjected to be analyzed. Analysis was performed by computing the synchronization of the EEGs and the conditions congruent vs. non-congruent were compared using statistical tools. The obtained results demonstrate that scalp EEG ccould be used as a tool to investigate the neural dynamics of emotional valence and discriminate various emotions (angry, happy and neutral stimuli).

Protective effects of social networks on disability among older adults in Spain

The loss of autonomy at advanced ages is not only associated with ageing, but also with the characteristics of the physical and social environment. Recent investigations have shown that social networks, social engagement and participation act like predictors of disability among the elderly. The aim of this study is to determine whether social networks are related to the development and progression of disability in the early years of old age. The source of data is the first wave of the survey "Processes of Vulnerability among Spanish Elderly", carried out in 2005 to a sample of 1 244 individuals. The population object of study is the cohort aged 70 to 74 years in metropolitan areas (Madrid and Barcelona) and not institutionalized. Disability is measured by the development of basic activities of daily life (ADL), and instrumental activities of daily life (IADL). The structural aspects of the social relationships are measured through the diversity of social networks and participation. We used the social network index (SNI). For each point over the SNI, the risk of developing any type of disability decreased by 49% (HR = 0.51, 95%CI = 0.31-0.82). The SNI was a decisive factor in all forecasting models constructed with some hazard ratios (HR) that ranged from 0.29 (95%CI = 0.14-0.59) in the first model to 0.43 (95%CI 0.20-0.90) in the full model. The results of the present study showed a strong association between an active social life, emotional support provided by friends and confidents and disability. These findings suggest a protective effect of social networks on disability. Also, these results indicate that some family and emotional ties have a significant effect on both the prevalence and the incidence of disability.

Spontaneous Speech and Emotional Response modeling based on One-class classifier oriented to Alzheimer Disease diagnosis

The purpose of our project is to contribute to earlier diagnosis of AD and better estimates of its severity by using automatic analysis performed through new biomarkers extracted from non-invasive intelligent methods. The methods selected in this case are speech biomarkers oriented to Sponta-neous Speech and Emotional Response Analysis. Thus the main goal of the present work is feature search in Spontaneous Speech oriented to pre-clinical evaluation for the definition of test for AD diagnosis by One-class classifier. One-class classifi-cation problem differs from multi-class classifier in one essen-tial aspect. In one-class classification it is assumed that only information of one of the classes, the target class, is available. In this work we explore the problem of imbalanced datasets that is particularly crucial in applications where the goal is to maximize recognition of the minority class as in medical diag-nosis. The use of information about outlier and Fractal Dimen-sion features improves the system performance.

La influència de les dinàmiques de grup en la millora de la cohesió de grup i l’estabilitat emocional dels infants

En aquest estudi qualitatiu s’investiga la influència de les dinàmiques de grup en la millora de la cohesió de grup i l’estabilitat emocional dels infants. La mostra està constituïda per 24 infants, d’edats compreses entre els 5 i 6 anys, i per una mestra de 58 anys. Es realitza una intervenció educativa, basada en quatre dinàmiques de grup diferents, per tal d’avaluar la seva incidència en relació a la cohesió de grup i l’estabilitat emocional dels infants. Els instruments utilitzats són de naturalesa qualitativa, concretament, l’entrevista i l’observació, que s’apliquen pre i post intervenció per tal d’identificar possibles canvis. En els resultats, no es poden observar grans canvis a nivell de cohesió de grup ni d’estabilitat emocional dels infants, però sí, una actitud positiva i de motivació en relació a l’aplicació de dinàmiques de grup. La curta durada de la intervenció educativa ha estat la principal limitació d’aquesta investigació, fet pel qual no s’han pogut extreure uns resultats significatius. És per això que a les conclusions es mostren un seguit d’aspectes a tenir en compte en futurs estudis.

Immunological aspects of Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (copd) is a major cause of illness and death throughout the world. It affects about 10% of the general population, but its prevalence among heavy smokers can reach 50%.COPD is the fourth leading cause of death in most industrialized countries, and it is projected to be the third leading cause of death worldwide by 2020. Tobacco smoking is the primary risk factor for the development of COPD, but other factors, such as burning biomass fuels for cooking and heating, are important causes of COPD in many developing countries....

Las emociones como variables relacionadas con el cambio de hábitos de salud en familiares y amigos próximos de enfermos de cáncer

Study of the changes in health habits of 105 cancer patients’ relatives and close friends after the diagnosis. The aim is to try to verify whether the knowledge of the disease has got some impact in the modification of their life styles. The emotional alterations influence in this change of behaviour has been analysed futhermore. An interview of own creation and HADS (Anxiety Hospital and Depression Scale of Zigmond and Snaith, 1983) instrument, in a Spanish and a Catalan version, were used with this aim. The results show that 21.1% of the participants presented positive changes in their health habits after the diagnosis of the relative or close friend and 11.5% showed negative changes. In relation to the role of the emotions, averages of anxiety (14,33; d.t.=4,98) and depressive (10,17; d.t.=4,93) symptoms were higher in those subjects who made negative changes than in those who did not make any change (9,32; d.t.=5,37 and 6,33; d.t.=4,64). In addition, the youngest participants, with more depressive symptoms and who visit the subject more often, are those who become more assets modifying health habits. The results suggest that emotional alterations, mainly depressive symptoms, are associated with negative change and, therefore, it would be suitable to lend some type of attention to these alterations in the population studied with the purpose of improving their present and future health

Personality traits and psychopathology predict burnout symptoms after two years in a sample of Catalan police officers

The operational aspects of psychological assessment are well documented (e.g. Murphy and Davidshofer, 1994). Essentially, the process involves the administration of one or more valid psychological tests in order to assess a person’s suitability to a task or situation. The resulting data and report are then used by police psychologists to assist in determining the suitability of the applicant for police duties. In Catalunya, this task is carried out during basic training for police career agent in the evaluation of psychological conditions for the use of the weapon. Police work can be one of the most stressful jobs, and it frequently leads to the development of burnout syndrome. In their day-to-day tasks, police officers are constantly subjected to various stressors (de la Fuente, Aguayo, Vargas and Cañadas, 2013). The most widely accepted definition of the burnout syndrome is one that describes it as a response to chronic work stress made up of three components: emotional exhaustion, depersonalisation and low personal accomplishment (Maslach & Jackson, 1981). Some studies showed that personality characteristics, and positive and negative affectivity explained significant variance in each of the burnout dimensions (Alarcon, Eschleman and Bowling, 2009).

Drug abuse, brain calcification and glutamate-induced neurodegeneration

Positive and negative reinforcing systems are part of the mechanism of drug dependence. Drugs with abuse potential may change the manner of response to negative emotional stimuli, activate positive emotional reactions and possess primary reinforcing properties. Catecholaminergic and peptidergic processes are of importance in these mechanisms. Current research needs to understand the types of adaptations that underlie the particularly long-lived aspects of addiction. Presently, glutamate is candidate to play a role in the enduring effects of drugs of abuse. For example, it participates in the chronic pathological changes of corticostriatal terminals produced by methamphetamine. At the synaptic level, a link between over-activation of glutamate receptors, [C(a2+)](i) increase and neuronal damage has been clearly established leading to neurodegeneration. Thus, neurodegeneration can start after an acute over-stimulation whose immediate effects depend on a diversity of calcium-activated mechanisms. If sufficient, the initial insult results in calcification and activation of a chronic on-going process with a progressive loss of neurons. At present, long-term effects of drug dependence underlie an excitotoxicity process linked to a polysynaptic pathway that dynamically regulates synaptic glutamate. Retaliatory mechanisms include energy capability of the neurons, inhibitory systems and cytoplasmic calcium precipitation as part of the neuron-glia interactions. This paper presents an integrated view of these molecular and cellular mechanisms to help understand their relationship and interdependence in a chronic pathological process that suggest new targets for therapeutic intervention.

Estudio del desarrollo y conectividad de las neuronas vasotocinérgicas en el prosencéfalo de pollo

En este Trabajo de Fin de Grado se estudia el origen embrionario de las distintas poblaciones neuronales que forman la amígdala medial extendida. La amígdala es una estructura del cerebro anterior involucrada en otorgar un significado emocional a los estímulos ambientales y en el control de distintos aspectos del comportamiento social (p.ej. comportamientos sexual, maternal, agresivo y afiliativo). Ante dichos estímulos, la amígdala pone en marcha una serie de reacciones de carácter motor, autonómico y endocrino que constituyen la respuesta emocional. Algunos desórdenes de carácter neuropsiquiátrico en humanos están relacionados con una disfunción en el control de las emociones y del comportamiento social, y varios de ellos se asocian a alteraciones en el desarrollo de la amígdala. El objetivo del presente trabajo ha sido investigar el origen de las neuronas de la amígdala medial extendida en embriones de pollo (E15 y E18) mediante ensayos de inmunocitoquímica, técnica utilizada para localizar las células que contienen el neuropéptido vasotocina (AVT) y proteínas reguladoras del desarrollo (la producida a partir del gen Otp) para ayudar en la delimitación de los distintos dominios embrionarios del prosencéfalo y distintas subdivisiones de la amígdala extendida. Los resultados de estos ensayos se combinaron con ensayos de trazado de conexiones para analizar la conectividad de las neuronas vasotocinérgicas de esta estructura. Los resultados obtenidos sugieren que las neuronas AVT-positivas podrían derivar del dominio Supra-Opto-Paraventricular (SPV), y algunas poblaciones alcanzarían su posición definitiva dentro del propio dominio por migración radial, mientras que otras invadirían otros dominios cerebrales por migración tangencial. En conclusión, la investigación proporciona importantes datos que clarifican aspectos relevantes del desarrollo y organización adulta de la amígdala extendida, y ayuda a establecer las bases para una mejor comprensión del control neural de las emociones y el comportamiento social en condiciones normales y patológicas.

L’educació emocional a través de la música per afavorir la convivencia l’aula en l’Educació Primària

L’educació emocional cada dia guanya més rellevància en l’àmbit educatiu. S’està comprovant que les emocions estan molt lligades al desenvolupament intel·lectual i social de les persones. La pràctica inclosa en aquest treball pretén afirmar la hipòtesi de que l’educació emocional a través de la música afavoreix la convivència a l’aula. Grans teòrics, al llarg de la història, han destinat part de la seva carrera a l’estudi de l’evolució del concepte d’emoció i les diferents vessants relacionades amb aquesta, com la intel·ligència emocional i/o l’educació emocional. L’ús de la musica com a recurs per treballar l’educació emocional ha permès un progrés en la convivència a l’aula, gràcies al seu efecte socialitzador.

Valoració de la qualitat de vida dels familiars de pacients amb fibromiàlgia

Fonament i objectiu: La Fibromiàlgia (FM) és una malaltia reumàtica caracteritzada per dolor generalitzat, que afecta a un tant per cent elevat de la població general , majoritàriament dones i d’etiologia desconeguda, i que pensem que no afecta tan sols als qui la pateixen, sinó que també als seus familiars. En aquest estudi s’han avaluat diferents variables com l’impacte emocional, la vida social, aspectes econòmics i laborals i altres activitats en familiars de primer grau de pacients amb FM. L’objectiu principal és determinar quin és el grau d’afectació negativa en la seva qualitat de vida. Material i mètodes: Es va fer un estudi observacional clínic a un grup de 27 familiars de 1er grau que convivien a la mateixa casa que els respectius afectats per FM. Se’ls va passar un qüestionari ad- hoc de 16 preguntes tancades, basades en estudis previs , i també una entrevista oberta amb l’objectiu de reforçar les dades estadístiques. Les entrevistes es varen fer a la Unitat de Fibromiàlgia de l’Hospital Santa Maria de Lleida. Resultats: Es va entrevistar a 27 familiars, 85’2 % homes, la majoria de entre 51 – 70 anys (63%). El 85’2 % eren casats, amb estudis primaris el 59’3% i el 88% tenien coneixements sobre la malaltia del familiar afectat. El percentatge de familiars que van opinar que hi havia una minva del grau de felicitats amb la malaltia era del 74’1%. El 85% no havia pensat mai en trencar la relació familiar. El 70% referien canvis en la vida social i relacional arrel del diagnòstic de FM , un 88’9% havien tingut que augmentar l’ajut en tasques domèstiques i el 70’4% patien efectes econòmics negatius arrel de la malaltia. La relació sexual es va veure afectada en un 85% dels casos, en canvi no es varen veure alteracions del son ni de la percepció de salut. Conclusions: El fet de conviure amb una persona afectada de FM suposa pèrdua del grau de felicitat i canvis en la vida social, relacional i sexual amb empitjorament del nivell econòmic.

Nationalist neoliberalism? Minority Nationalism, competitiveness and the urban question

Presentation at: II IAS Annual Research Programme International ConferenceSession: Governing Regions, Lancaster Setember 17-19 2007

Afrontamiento de situaciones de hostilidad y desempeño de la función directiva. Planteamientos y reflexiones a raíz de una actividad de formación permanente de directivos de centros educativos de titularidad pública

The intervention in the organized conflicts and, particularly, the confrontation of hostile situations (based on the emotional alteration, the strain, the verbal aggressiveness, etc) is one of the aspects that worry the principals of the educative centres and, therefore, a main attention must be given to the initial and permanent training to have managing duties. Throughout the text we take some aspects into account in the development of these managing skills:a) we set the distinctive features; b) we answer to the dilemma about the existence of improvement possibilities; c) we state the need to star from the motivation and the active participation of the principals in their own personal development and, finally, d) we contribute with the design of a training activity to develop skills to confront hostile situations, addressed to the principals of primary and secondary schools, that was done in Girona, in November 2005

Feature selection for automatic analysis of emotional response based on nonlinear speech modeling suitable for diagnosis of Alzheimer׳s disease

Alzheimer׳s disease (AD) is the most common type of dementia among the elderly. This work is part of a larger study that aims to identify novel technologies and biomarkers or features for the early detection of AD and its degree of severity. The diagnosis is made by analyzing several biomarkers and conducting a variety of tests (although only a post-mortem examination of the patients’ brain tissue is considered to provide definitive confirmation). Non-invasive intelligent diagnosis techniques would be a very valuable diagnostic aid. This paper concerns the Automatic Analysis of Emotional Response (AAER) in spontaneous speech based on classical and new emotional speech features: Emotional Temperature (ET) and fractal dimension (FD). This is a pre-clinical study aiming to validate tests and biomarkers for future diagnostic use. The method has the great advantage of being non-invasive, low cost, and without any side effects. The AAER shows very promising results for the definition of features useful in the early diagnosis of AD.
