Feature Selection for Speech Emotion Recognition in Spanish and Basque: On the Use of Machine Learning to Improve Human-Computer Interaction

Study of emotions in human-computer interaction is a growing research area. This paper shows an attempt to select the most significant features for emotion recognition in spoken Basque and Spanish Languages using different methods for feature selection. RekEmozio database was used as the experimental data set. Several Machine Learning paradigms were used for the emotion classification task. Experiments were executed in three phases, using different sets of features as classification variables in each phase. Moreover, feature subset selection was applied at each phase in order to seek for the most relevant feature subset. The three phases approach was selected to check the validity of the proposed approach. Achieved results show that an instance-based learning algorithm using feature subset selection techniques based on evolutionary algorithms is the best Machine Learning paradigm in automatic emotion recognition, with all different feature sets, obtaining a mean of 80,05% emotion recognition rate in Basque and a 74,82% in Spanish. In order to check the goodness of the proposed process, a greedy searching approach (FSS-Forward) has been applied and a comparison between them is provided. Based on achieved results, a set of most relevant non-speaker dependent features is proposed for both languages and new perspectives are suggested.

Ativismo X entretenimento: tensões vivenciadas no discurso e nas práticas do Hip-Hop

A presente dissertação aborda as tensões vivenciadas no universo do hip-hop provenientes das relações de seus integrantes com a idéia de uma essência que definiria tal grupo cultural. Para tanto, trazemos uma breve problematização do conceito de identidade, como pano de fundo desta discussão, acreditando na sua relação com essa identidade essencializada do hip-hop. Portanto, tal contexto será analisado trabalhando com a hipótese de que essa relação ocorre de forma diferente, no discurso e nas práticas deste movimento. São priorizados os eixos temáticos política e mídia para o estudo destas problemáticas

Conselhos escolares nas escolas municipais de Duque de Caxias:tensões e perspectivas

A pesquisa objetivou investigar a formação dos conselheiros escolares nas Escolas Municipais de Duque de Caxias a partir da adesão do Município ao Programa Nacional de Fortalecimento dos Conselhos Escolares, coordenado pela Secretaria de Educação Básica do Ministério da Educação. Como o exame das ações do Programa e a identificação das mesmas no referido município perpassam pelos níveis macro, meso e micro do sistema educacional, a metodologia constituiu-se de pesquisa bibliográfica, análise de documentos, construção e retrospectiva histórica em torno do princípio da gestão democrática e dos conselhos escolares; de entrevistas no MEC, na Secretaria Municipal de Educação, com os diretores de duas escolas da rede de ensino e grupo focal com o Conselho Escolar, além da observação nas escolas. Tendo como base o princípio da democracia e a construção da prática democrática nas escolas, por meio da gestão, percebem-se os conselhos escolares como segmentos representativos, tanto da possibilidade de transformação como de manutenção dos processos que envolvem a transparência, a autonomia e a participação da comunidade escolar na gestão das escolas. A verificação das ações de um Programa governamental em escala nacional, envolvendo a colaboração entre os entes federados, permite desmistificar o distanciamento entre as esferas dos sistemas de ensino neste processo que envolve a capacitação dos conselheiros escolares. A pesquisa revelou que, embora o Município de Duque de Caxias tenha aderido ao Programa, ainda não promoveu ações no sentido de formação de seus Conselheiros Escolares. Não obstante, uma das escolas observadas no estudo promove uma dinâmica articulada, em seu funcionamento, no que se refere à participação da comunidade escolar e local na gestão da escola

The Spanish corporate structure through interlocking directorates

[EN] The aim of this paper is to determine to what extent globalization pressures are changing interlocking directorate networks modeled on continental capitalism into Anglo-Saxon models. For this purpose we analyse the Spanish network of interlocks, comparing the present structure (2012) with that of 1993 and 2006. We show how, although Spanish corporative structure continues to display characteristics of the continental economies, some major banks are significantly reducing industrial activity. Nevertheless, the financial organizations continue to maintain a close relationship with sectors such as construction and services. The analysis of the network of directorates shows a retreat in activity of industrial banking in Spain. Two large Spanish financial institutions, BSCH and La Caixa, continue to undertake activities of industrial banking in 2006, but this activity is significantly reduced in 2012. According to the theories on the role of the interlocking directorates, the companies in these sectors assure their access to banking credit by incorporating advisors from financial organizations to their board of directors. We cannot conclude that the structure of the Spanish corporate network has become a new case of Anglo-Saxon structure, but we got indications that are becoming less hierarchic as banks seem to slowly abandon centrality positions. This is especially salient if we compare the networks of 2006 and 2012, which show a continuing decrease of the role of banks and insurance companies in the network.

Analysis of Body Composition and Food Habits of Spanish Celiac Women

The purpose of the present work was both to analyze composition of Spanish celiac women and to study the food habits and gluten-free diet of these celiac patients, in order to determine whether they achieve a balanced and healthy diet as well as to highlight nutritional qualitative and/or quantitative differences. 54 adult celiac women (34 +/- 13 years) took part in the six-month study. Height, weight and body composition were measured. An analysis of energy consumption and of the macronutrient distribution of their diet was carried out. Their fulfillment of micronutrient intake recommendations was verified. Participants showed a Body Mass Index of 21.6 +/- 2.4 kg/m(2). Energy Intake was slightly lower than the Dietary Reference Intakes. Excessive protein apart from over-consumption of fat was observed. More than three quarters of participants consumed meat in excess. Carbohydrate consumption along with that of fiber was below recommended levels. Vitamin D, iron, and iodine had a low percentage of recommendation compliance. In general, participants followed the recommendations of dairy products and fruit intake whereas vegetable consumption was not enough for the vast majority. We conclude that although the diet of celiac women does not differ much from the diet of general population, some considerations, such as reducing fat and protein consumption and increasing fiber intake, must be taken into account.

The Spanish Pension System: Overview and Long-Term Projections

In the middle of the so-called pension crisis, the ageing of population and the sharp decrease in affiliations to Social Security are threatening the well-functioning of the Spanish public pension system. The purpose of this paper is to present the main challenges to be faced by the Spanish pension system, as well as to shed light on the main determinants that will condition the evolution of pension expenditure over GDP along the following decades. This quantitative analysis, which considers the 2011 and 2013 pension reforms, uses the latest data on the Spanish demographic, labor market and institutional factors in order to project the evolution of the system from the expenditure side up to 2060. For the purpose of analyzing the dynamics and the underlying drivers of pension expenditure, the so-called aggregate accounting approach will be utilized. The alternative scenarios proposed allow for exploring the robustness of the results within the baseline scenario, which constitutes the reference point of projections in the exercise. The analysis concludes that, by the end of the projected period, Spain will count on a similar public pension expenditure ratio as the current one.
