La presente investigación se realizó con los objetivo de determinar las principales causas que obstaculizan la agilización del proceso de adopción en el Ministerio de la Familia, en Managua. Se conoce que la principal obstaculización del proceso de adopción incide en la vía administrativa y se describe como larga y tardía, provocando en las parejas que quieren adoptar desistir de la idea, ya que les resulta agotador, al igual se pierde la oportunidad de brindar una familia a un menor, vulnerando su derecho, y por ello se ha planteado como interrogante ante este problema, ¿Cuáles son las principales causas en la práctica que obstaculizan la agilización del proceso de adoptar en parejas que asisten al Ministerio de la Familia durante el periodo 2005-2010? Se ha estructurado el presente trabajo en cuatro capítulos: Capítulo I: Generalidades sobre el proceso de Adopción Capítulo II: Procedimiento Administrativo de la Adopción Capítulo III: Comparación del proceso de Adopción dispuesto en el proyecto Código de Familia con el procedimiento vigente Capítulo IV: Causas que dificultan la agilización del Proceso Administrativo de Adopción a través del Estudio de Casos. La presente investigación es de tipo cualitativa descriptiva ya que se pretende describir las causas que obstaculizan el procedimiento administrativo de la adopción partir de la ley vigente y del estudio de casos para contrastarlos. Su diseño no incluye hipótesis sino la realización de preguntas directrices las cuales se utilizaron como base del desarrollo de la investigación. Se utilizó como técnica de recopilación de información la revisión documental, así como la realización de entrevistas a los encargados en el área administrativa del Ministerio de la Familia,como máxima autoridad en el proceso administrativo de adopción y finalmente la Principales causas que obstaculizan la agilización del proceso de adopción en el Ministerio de la Familia, en el año 2005-2010 en Managua” 8 revisión de expedientes que permitió determinar las causas que impiden que los procesos sean ágiles y expeditos

Lexicon-based sentiment analysis in texts using Formal Concept Analysis

In this paper, we present a novel approach for sentiment analysis that uses Formal Concept Analysis (FCA) to create dictionaries for classification. Unlike other methods that rely on pre-defined lexicons, our approach allows for the creation of customised dictionaries that are tailored to the specific data and tasks. By using a dataset of tweets categorised into positive and negative polarity, we show that our approach achieves a better performance than other standard dictionariesThis research is partially supported by the State Agency of Research (AEI), the Spanish Ministry of Science, Innovation, and Universities (MCIU), the European Social Fund (FEDER), the Junta de Andalucía (JA), and the Universidad de Málaga (UMA) through the FPU19/01467 (MCIU) internship and the research projects with reference PGC2018-095869-B-I00, TIN2017-89023-P, PID2021-127870OB-I00 (MCIU/AEI/FEDER, UE) and UMA18-FEDERJA-001 (JA/ UMA/ FEDER, UE).

Fuzzy algebras of concepts

Preconcepts are basic units of knowledge that form the basis of formal concepts in formal concept analysis (FCA). This paper investigates the relations among different kinds of preconcepts, such as protoconcepts, meet and join-semiconcepts and formal concepts. The first contribution of this paper, is to present a fuzzy powerset lattice gradation, that coincides with the preconcept lattice at its 1-cut. The second and more significant contribution, is to introduce a preconcept algebra gradation that yields different algebras for protoconcepts, semiconcepts, and concepts at different cuts. This result reveals new insights into the structure and properties of the different categories of preconcepts.Partial funding for open access charge: Universidad de Málag

Export Performance in Spanish Wineries: the Role of Human Capital and Quality Management System

This version of the article has been accepted for publication, after peer review, but is not the Version of Record and does not reflect post-acceptance improvements, or any corrections. The Version of Record is available online at: https://doi.org/10.1504/EJIM.2018.091372[Abstract] The aim of this paper is to research the effect of human capital and Quality Management System (QMS) on the export performance of wine firms. The empirical analysis is carried out using data from a sample of Spanish wineries and performing Tobit regression models. In relation to human capital, the results show that only the specific human capital is associated with superior export performance of wineries whereas the general human capital although it has a positive coefficient, it is not statistically significant on the export performance of wine firms. The results related to Quality Management System show that those wine firms certified with the ISO 9000 standard of QMS have better export performanc

Detection of unfavourable urban areas with higher temperatures and lack of green spaces using satellite imagery in sixteen Spanish cities.

This paper seeks to identify the most unfavourable areas of a city in terms of high temperatures and the absence of green infrastructure. An automatic methodology based on remote sensing and data analysis has been devel oped and applied in sixteen Spanish cities with different characteristics. Landsat-8 satellite images were selected for each city from the July-August period of 2019 and 2020 to calculate the spatial variation of land surface temperature (LST). The Normalized Difference Vegetation Index (NDVI) was used to determine the abundance of vegetation across the city. Based on the NDVI and LST maps created, a k-means unsupervised classification clustering was performed to automatically identify the different clusters according to how favourable these areas were in terms of temperature and presence of vegetation. A Disadvantaged Area Index (DAI), combining both variables, was developed to produce a map showing the most unfavourable areas for each city. Overall, the percentage of the area susceptible to improvement with more vegetation in the cities studied ranged from 13 % in Huesca to 64–65 % in Bilbao and Valencia. The influence of several factors, such as the presence of water bodies or large buildings, is discussed. Detecting unfavourable areas is a very interesting tool for defining future planning strategy for green spaces

Analysis of functional connectome pipelines for the diagnosis of autism spectrum disorders

This paper explores the effect of using different pipelines to compute connectomes (matrices representing brain connections) and use them to train machine learning models with the goal of diagnosing Autism Spectrum Disorder. Five different pipelines are used to train six different ML models, splitting the data into female, male and all subsets so we can also research the effect of considering male and female patients separately. Our results conclude that pipeline and model choice impact results, along with using general or specific models.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Spillovers entre el S&Poor500 y los principales EMBIG latinoamericanos

This work performs an analysis of spillover effects between U.S. stock returns and changes in EMBI Global indices in Argentina, Brazil, Colombia, Mexico and Peru. A total spillover index is estimated to show significant increases at the turn of the century and during the global financial crisis. Breaking down the index into its directional components shows that the main sources of spillover among the markets analyzed are the U.S. stock market and the Brazilian bond index. An important limitation is that the EMBIGs of other Latin American countries are left out of the study and the main implication of the results is that it shows how the behavior of these instruments relates, which can be useful for portfolio decision-making. It is also noteworthy that the main recipients of spill effects are the indices of the bonds of Peru and Mexico, while the Argentine bond index is the least affected by external shocks.En este trabajo se realiza un análisis de los efectos de derrame (spillover ) entre los rendimientos accionarios de Estados Unidos y los cambios en los índices EMBI Global de Argentina, Brasil, Colombia, México y Perú. Se estima un índice del spillover total que muestra alzas importantes a principios de siglo y durante la crisis financiera mundial. Al descomponer dicho índice en sus componentes direccionales se observa que las principales fuentes de spillover entre los mercados analizados son el mercado accionario de Estados Unidos y el índice de los bonos brasileños. Una limitación importante es que quedan fuera del estudio los EMBIG de otros países latinoamericanos y la principal implicación de los resultados es que muestra cómo se relaciona el comportamiento de esos instrumentos, lo que puede ser útil para la toma de decisiones de portafolio. También es de destacarse que los principales receptores de efectos derrame son los índices de los bonos de Perú y México, en tanto que el índice de los bonos argentinos son los menos afectados por los choques externos

Influence of longitudinal clips in thermal stresses and deflection in solar tubular receivers

Mechanical boundary conditions in tubular receivers of solar power tower plants have a main role in the thermal stress distribution and tube deflection. Longitudinal supports, particularly, has an strong influence on stress and displacements, since they prevent the tube bending. In this work, the influence of longitudinal supports, on tube deflection and stress has been studied in external-cylindrical receivers, using an analytical methodology, which it is able to take into account the tube geometry in the deflection calculation. Therefore, real tube geometry with elbows can be considered. Results for two aiming strategies, one equatorial and another that flattens the heat flux, have been compared for different clips distances, from 1 to 9 meters. The analytical methodology developed in Matlab provides lower computational cost than the numerical model developed in Abaqus. Results show that clip distribution has a significant impact on thermal stress. For clips distance of 2 meters or lower, the generalised plane strain solution provides the stress distribution along the tube accurately, with a tube deflection lower than 1 millimetrer. When clips distance increases, the longitudinal stress distribution differs from the plane strain case, and the deflection increases to non-desirable values. Deflection is greater at tube ends, and aiming strategies that flatten the heat flux increases the displacement in that regions.This work has been supported by the Ministerio de Ciencia, Innovacion y Universidades (Projects RTI2018-096664-B-C21 and RTI2018-096664-B-C22 (MICINN/FEDER, UE)) of the Spanish Government and the Iberdrola Foundation Spain under the fellowship "Ayudas a la investigación en energía y medio ambiente 2018"
