Affective computing for smart operations: a survey and comparative analysis of the available tools, libraries and web services

In this paper, we make a deep search of the available tools in the market, at the current state of the art of Sentiment Analysis. Our aim is to optimize the human response in Datacenter Operations, using a combination of research tools, that allow us to decrease human error in general operations, managing Complex Infrastructures. The use of Sentiment Analysis tools is the first step for extending our capabilities for optimizing the human interface. Using different data collections from a variety of data sources, our research provides a very interesting outcome. In our final testing, we have found that the three main commercial platforms (IBM Watson, Google Cloud and Microsoft Azure) get the same accuracy (89-90%). for the different datasets tested, based on Artificial Neural Network and Deep Learning techniques. The other stand-alone Applications or APIs, like Vader or MeaninCloud, get a similar accuracy level in some of the datasets, using a different approach, semantic Networks, such as Concepnet1, but the model can easily be optimized above 90% of accuracy, just adjusting some parameter of the semantic model. This paper points to future directions for optimizing DataCenter Operations Management and decreasing human error in complex environments

Mujeres en las "guerrillas" peruanas de finales del siglo XX

En las dos últimas décadas del pasado siglo se formaron y desaparecieron movimientos armados en la sociedad peruana, popularmente llamados “guerrillas”. Dichos grupos se enfrentaron al Estado provocando una fuerte oleada de violencia política. La participación femenina en todo el proceso fue muy amplia e inesperada. Tras una investigación cualitativa en la que se entrevistó a mujeres de los dos grupos armados más importantes, Partido Comunista del Perú-Sendero Luminoso (PCP-SL) y Movimiento Revolucionario Tupac Amaru (MRTA), presentamos las razones sociales e identitarias que condujeron a las mujeres a su implicación en esta expresión de violencia política, así como la problemática de fractura y reconstrucción identitaria que se vieron obligadas a realizar y la evaluación de sus experiencia

La estereotipación de las variedades del español en «Ocho apellidos catalanes»: un análisis lingüístico

El presente Trabajo de Fin de Grado tiene como objetivo analizar las principales variedades del español de la película «Ocho apellidos catalanes»: el andaluz (concretamente la variedad sevillana), la variedad del español de Cataluña y la variedad del español del País Vasco. Asimismo, pretende establecer si los rasgos lingüísticos característicos de dichas variedades se muestran fieles a la realidad o si por el contrario se exageran dando lugar a una estereotipación. Para resolver estas cuestiones, se llevará a cabo un exhaustivo análisis lingüístico, con el fin de extraer conclusiones certeras y confirmar si la estereotipación de las variedades es un recurso comúnmente usado para aportar comicidad a los productos audiovisuales.This Final Degree Project aims to analyse the main varieties of Spanish present in the film «Spanish Affair 2» (in Spanish, «Ocho apellidos catalanes»): the Andalusian variety (specifically the Sevillian variety), the variety of Spanish from Catalonia and the variety of Spanish from the Basque Country. It also seeks to establish whether the characteristic linguistic features of these varieties are accurately represented or whether, on the contrary, they are exaggerated, resulting in stereotyping. In order to answer these questions, we will carry out an exhaustive linguistic analysis to draw reliable conclusions and to confirm if the varieties are commonly stereotyped to add comedy to audiovisual products.Universidad de Granada.

Lexical Areas and Linguistic Domains in the Northwest of the Iberian Peninsula

Os atlas lingüísticos constitúen unha excelente fonte de datos para coñecer a distribución xeográfica das va-riedades e tamén o modo en que estas se interrelacionan, unha vez que rexistran nas súas cartas as variantes recorrentes en determinadas áreas asociadas a unha mesma variable. A pesar do valor destas obras e da riqueza da información que fornecen para a investigación nos distintos ámbitos da lingüística, deica agora son poucos aínda os traballos que as utilizaron para descubrir as relacións de contacto entre dominios lingüísticos. Entre as razóns que explican esta desconsideración están a dificultade para tratar datos en formato cartográfico e o simple descoñecemento do valor da información que albergan estas obras. Neste traballo preséntase unha análise exploratoria dun pequeno grupo de pre-guntas da sección de léxico dos cadernos do Atlas Lingüístico de la Península Ibérica (ALPI) pertencentes a unha área do noroeste peninsular que comprende distintos dominios lingüísticos romances. As variantes léxicas seleccionadas corresponden a dez conceptos asociados con denominacións de partes do corpo humano. Os resultados do estudo com-páranse e póñense en relación con algunhas investigacións previas que abordaron os límites dos dominios lingüísticos nesta zona da península. Ademais, dáse conta das similitudes e semellanzas na distribución das variantes de distintos niveis de análise xeolingüística e identifícanse algúns padróns de distribución de variantes léxicasLos atlas lingüísticos constituyen una excelente fuente documental para conocer la distribución geográfica de las variedades y también el modo en que éstas se interrelacionan, dado que registran en sus mapas las variantes asociadas a una misma variable en un área territorial.

Des-pite the value of such works and the wealth of information they provide to researchers in a range of linguistic subdisci-plines, few studies have made use of them to explore contact between linguistic domains. Two reasons for this are the difficulty of processing cartographic data and a lack of awareness of the valuable information that such materials con-tain. This paper presents the results of an exploratory analysis of a small set of items in the lexical section of the part ofthe Atlas Lingüístico de la Península Ibérica (ALPI) that covers the northeast of the Iberian Peninsula, where se-veral distinct Romance languages coincide. The selected lexical variants have to do with ten concepts involving parts of the human body. The results of an analysis of the linguistic variants are compared and related to previous studies of the borders between the language areas cove-red, in order to chart similarities and correspondences in the distribution of variants at different levels of geolin-guistic analysis and to identify the distribution patterns of variantsO traballo é un resultado parcial dos proxectos “Contacto e cambio lingüístico en galego”, financiado polo Ministerio de Economía y Competitividad (FFI2015-65208-P) e o Fondo Europeo de Desenvolvemento Rexional (FEDER, marco financeiro plurianual 2014‐2020), e “Variación y cambio en los dominios gallego y portugués en el siglo XX: análisis del habla rural a partir de materiales geo-lingüísticos” (financiado por MCIU/AEI/FEDER, UE; PGC2018-095077-B-C44)S

Evidence of validity and measurement invariance by gender of the Vaccination Attitudes Examination (VAX) scale in Colombian university students

Background: Having a valid tool to assess attitudes toward vaccination and identify the concerns that drive vaccine refusal can facilitate population studies and help guide public health interventions. The objective of this study has been to adapt the Vaccination Attitudes Examination (VAX) scale in Colombian university students and to study its psychometric properties in a non-probabilistic sample of 1074 Colombian university students. Methods: A confirmatory factor analysis was used to study the factorial structure. A structural equation model was tested to study concurrent validity and to check whether the factors predicted having received the coronavirus vaccine. Gender-based measurement invariance was also studied for the best model. Results: The results support the structure of four related factors. The composite reliability index was good for all the factors, but the average variance extracted was not as good for the second factor. There was strong measurement invariance by gender, and two factors are good predictors of being vaccinated or not. Conclusions: The VAX has shown construct and concurrent validity and is a reliable tool for evaluating attitudes towards vaccines in university students in Colombia. It may help guide the implementation of actions for the National Vaccination Plan and institutional policies

Short versus standard implants at sinus augmented sites: a systematic review and meta‑analysis

Background Short implants are proposed as a less invasive alternative with fewer complications than standard implants in combination with sinus lift. The aim of this systematic review and meta-analysis was to state the efficacy of placing short implants (≤ 6 mm) compared to standard-length implants (≥ 8 mm) performing sinus lift techniques in patients with edentulous posterior atrophic jaws. Efficacy will be evaluated through analyzing implant survival (IS) and maintenance of peri-implant bone (MBL). Methods Screening process was done using the National Library of Medicine (MEDLINE by PubMed), EMBASE, the Cochrane Oral Health, and Web of Science (WOS). The articles included were randomized controlled trials. Risk of bias was evaluated according to The Cochrane Collaboration’s tool. Weighted means were calculated. Heterogeneity was determined using Higgins (I2). A random-effects model was applied. Secondary outcomes such as surgical time, patient satisfaction, mucositis and peri-implantitis, pain, and swelling were analyzed. Results Fourteen studies (597 patients and 901 implants) were evaluated. IS was 1.02 risk ratio, ranging from 1.00 to 1.05 (CI 95%) (p = 0.09), suggesting that IS was similar when both techniques were used. MBL was higher in patients with standard-length implants plus sinus lift elevation (p = 0.03). MBL was 0.11 (0.01–0.20) mm (p = 0.03) and 0.23 (0.07–0.39) mm (p = 0.005) before and after 1 year of follow-up, respectively, indicating that the marginal bone loss is greater for standard-length implants. Discussion Within the limitations of the present study, as relatively small sample size, short dental implants can be used as an alternative to standard-length implants plus sinus elevation in cases of atrophic posterior maxilla. Higher MBL was observed in the groups where standard-length implants were used, but implant survival was similar in both groups. Moreover, with short implants, it was observed a reduced postoperative discomfort, minimal invasiveness, shorter treatment time, and reduced costs. Clinical Clinical relevance The low MBL promoted by short implants does contribute to a paradigm shift from sinus grafting with long implants to short implants. Further high-quality long-term studies are required to confirm these findings.Spanish GovernmentEuropean Commission PID2020-114694RB-I00 MINECO/AEI/FEDER/U

Multi-unit calibration rejects inherent device variability of chemical sensor arrays

Inherent sensor variability limits mass-production applications for metal oxide (MOX) gas sensor arrays because calibration for replicas of a sensor array needs to be performed individually. Recently, calibration transfer strategies have been proposed to alleviate calibration costs of new replicas, but they still require the acquisition of transfer samples. In this work, we present calibration models that can be extended to uncalibrated replicas of sensor arrays without acquiring new samples, i.e., general or global calibration models. The developed methodology consists in including multiple replicas of a sensor array in the calibration process such that sensor variability is rejected by the general model. Our approach was tested using replicas of a MOX sensor array in the classification task of six gases and synthetic air, presented at different background humidity and concentration levels. Results showed that direct transfer of individual calibration models provides poor classification accuracy. However, we also found that general calibration models kept predictive performance when were applied directly to new copies of the sensor array. Moreover, we explored, through feature selection, whether particular combinations of sensors and operating temperatures can provide predictive performances equivalent to the calibration model with the complete array, favoring thereby the existence of more robust calibration models

Desarrollo del prototipo AndaLAND para evaluar suelos agrícolas y agua en el marco del cambio climático

16 páginas.-- 7 figuras.-- 26 referencias.-- Annex 1. Equivalents of USDA and FAO soil classifications (IUSS Working Group WRB 2006)[ES]: There is a critical need to incorporate concerns on soil and water use and protection into land use planning policies and practices, not exclusively in protected areas, especially taking into account the widespread power transfer to local authorities regarding land-use decision making. Accordingly, it is extremely useful what Decision Support Systems (DSS) do on land use. AndaLAND is a prototype DSS which has been developed as a web-based application. It helps to define the vulnerability and the efficiency of the use and protection of soils in the selected target region: Andalusia (Southern Spain). AndaLAND integrates a complete catalogue of information on climate, soil and soil management, to make land vulnerability evaluation. By using Web Map Services (WMS), AndaLAND is fed with available databases from public mapping services (the Geographic Information System for the Common Agricultural Policy-SIGPAC) and other external sources (Microcomputed-based Land Evaluation Information System, MicroLEIS). Climate change scenarios are considered jointly with other relevant global change elements, such as land use change. Soil evaluation is based on decision rules that follow a decision tree. This method was established from Drools (a powerful hybrid reasoning system), using agrological rules for determining soil capacity in plots. The tool is capable of evaluating individually more than 6 million plots currently existing in the Andalusian region. AndaLAND’s final output is a report on the particular vulnerability of a user-specified plot. The report includes information on the plot’s geographical location, its environmental status regarding to (current and potential) impacts, degradation and/or pollution in the water-soil-crop system and eventual affections due to climate change-induced events. The report also provides practical recommendations for sustainable use and management of plots (in particular, for irrigated crops, these recommendations are linked to available irrigation technologies and water consumption).[PO]: Cada vez é mais evidente a necessidade de implementar políticas e práticas que integrem critérios de ordenamento do território para a proteção do uso do solo e da água, não só nas áreas protegidas, tendo em consideração o papel das autoridades locais e dos pequenos agricultores na tomada de decisão sobre os diversos usos do solo. Por isso, e uma vez que existe uma prática cada vez mais difundida no uso de Sistemas de Apoio à Decisão (SAD) para a gestão do uso do solo, o AndaLAND é apresentado como um protótipo dos SAD desenvolvido como uma aplicação web. Esta ferramenta permite determinar a vulnerabilidade e eficiência no uso e proteção do solo na área de estudo: Andaluzia (Sul de Espanha). O AndaLAND integra um catálogo abrangente de informações sobre o clima, solo e gestão da mesma, para permitir a avaliação da vulnerabilidade dos solos alvo. Usando serviços Web Map (WMS), o AndaLAND permite descarregar as informações dos bancos de dados de mapeamento de serviços públicos (Sistema de Informação Geográfica para a Política Agrícola Comum-SIGPAC) assim como de outras fontes diversas (sistemas de informação para a avaliação de serviços web do solo existentes MicroLEIS). Os cenários de alterações climáticas são construídos como informação relevante para prever os potenciais impactos associados com as mudanças no uso do solo. A avaliação global do solo é estabelecida a partir de regras definidas usando árvores de decisão. Este método foi implementado através do sistema Drools (sistema de regras de gestão), utilizando critérios agronómicos para determinar a capacidade agrológica das parcelas. Assim, esta ferramenta é capaz de avaliar individualmente mais de 6 milhões de explorações atualmente existentes na Andaluzia. O resultado final do uso AndaLAND é um relatório individual sobre a vulnerabilidade da parcela definida pelo utilizador como parcela-alvo. Esta documentação inclui informações sobre a localização geográfica da parcela, o seu estado ambiental em relação a atuais e potenciais impactos, possível fase de degradação e / ou contaminação no sistema solo-água-cultura e a robabilidade de ser afetada pelos efeitos associados às alterações climáticas. O relatório final inclui recomendações práticas para a utilização e gestão sustentável na parcela-alvo (especialmente no caso das culturas de regadio estas orientações referem-se às tecnologias de rega existentes e ao consumo de água).[ES]: Cada vez se hace más patente la necesidad de implementar políticas y prácticas de planificación territorial que integren criterios para la protección del uso del suelo y el agua, no sólo en las zonas naturales protegidas, y considerando a su vez el papel desempeñado por las administraciones locales y pequeños agricultores en la toma de decisiones sobre los distintos usos del suelo. Por ello, y dado que existe una práctica cada vez más generalizada en el uso de Sistemas de Ayuda a la Decisión (SAD) para la gestión de los usos del suelo, AndaLAND se presenta como un prototipo de SAD desarrollado como una aplicación web. Esta herramienta permite determinar la vulnerabilidad y la eficiencia en el uso y protección de los suelos en la región objetivo de estudio: Andalucía (S España). AndaLAND integra un catálogo muy completo sobre información climática, de suelos y de manejo de los mismos, para poder realizar la evaluación de la vulnerabilidad de suelos objetivo. Mediante el uso de Web Map Services (WMS), AndaLAND es capaz de volcar la información procedente de las bases de datos de servicios de cartografía públicos (el Sistema de Información Geográfica de la Política Agraria Común-SIGPAC), así como otras fuentes muy diversas (sistemas de información de evaluación de suelos ya existentes en servicios web, MicroLEIS). Los escenarios de cambio climático están incorporados como información relevante para poder predecir los posibles impactos asociados a los cambios de uso del suelo. La evaluación global del suelo se establece a partir de reglas definidas mediante árboles de decisión. Dicho método fue implementado a través del sistema Drools (sistema de gestión de reglas), utilizando criterios agronómicos para determinar la capacidad agrológica en las parcelas. De esta forma, la herramienta es capaz de evaluar individualmente más de 6 millones de explotaciones declaradas actualmente en Andalucía. El resultado final del uso de AndaLAND es un informe individual sobre la vulnerabilidad de la parcela objetivo definida por el usuario. Dicha documentación incluye información sobre la localización geográfica de la parcela, su estado medioambiental con respecto a actuales y potenciales impactos, la posible fase de degradación y/o contaminación en el sistema suelo-agua-cultivo, y la probabilidad de verse afectada por los efectos asociados al cambio climático. El informe final incorpora recomendaciones prácticas para el uso y gestión sostenible en la parcela objetivo (en particular, en el caso de cultivos de regadío estas pautas están referidas a tecnologías de riego existentes y hacia el consumo de agua).This research was funded by the Spanish Ministry of Economy and Competitiveness (MINECO) and the European Regional Development Fund (ERDF) within the framework of the new Precommercial Public Procurement (CPP). The AndaLAND DSS has been jointly developed by the Spanish National Research Council (CSIC), the Institute of Natural Resources and Agrobiology of Seville (IRNAS-CSIC) and two Spanish companies: INCLAM, specialized in water and environmental engineering; and EVENOR-TECH, specialized in Information and Comunication Technologies (ICT) applied to land use planning.Peer reviewe

Critical thinking among institutional academic advisors and sociodemographic, professional and academic variables: a multicenter correlation study

Background: In nursing education, essential skills include Critical Thinking (CT). There is scant evidence on how nurse educators could promote CT in students in a clinical context. Objective: To analyse the level of CT and correlated variables in healthcare nurses overseeing the clinicals of nursing undergraduates. Methods The study population were all nurse educators for clinicals at hospitals with nursing undergraduates. To evaluate the CT skills of nurses the Nursing Critical Thinking in Clinical Practice Questionnaire (N-CT-4 practice) was administered. Frequencies, percentages and measures of central tendency and scatter were obtained. A bivariate analysis was performed to analyze the correlation between the nurse educators' CT level and the sociodemographic, professional and academic levels. The nonparametric Mann-Whitney and Kruskal-Wallis tests were used to compare two independent groups. Statistical significance was defined as P <.05. Results: The total number of participants was 639. The highest mean CT level was seen in clinical nurses involved in undergraduate nursing instruction and with experience of up to 10 years (mean CT score = 372 (33.3), p=.007). Global CT levels were similar in women and men (mean CT score: 364 (31.9) in women and 358 (40.5) in men, p=.187), with statistically significant differences only observed in the intellectual and cognitive indicator (P =.022). Conclusions: CT levels are high in teaching healthcare professionals in the clinical environment
