The outcome-representation learning model: impairments in decision-making in adolescents with excess weight
Impairments in decision-making have been suggested as a predisposing factor to obesity development. Individuals with excess weight display riskier decisions than normal weight people. Furthermore, adolescence is a period of life in which risky behavior may increase. We aimed to investigate decision making applying the Outcome-Representation-Learning (ORL) model to the Iowa Gambling Task (IGT) in adolescents with excess weight. Twenty-nine excess weight and twenty-eight normal weight adolescents, classified according to their age-adjusted body mass index (BMI) percentile, participated in the study. Decision-making was measured using the IGT. A Bayesian computational ORL model was applied to assess reward learning, punishment learning, forgetfulness, win perseverance and deck perseverance. The IGT net score was lower in excess weight than normal weight adolescents (ß = 2.85; p <.027). Reward learning (95% HDI 0.011, 0.232]) was higher, while forgetfulness (95% HDI - 0.711, - 0.181]) and deck perseverance (95% HDI - 3.349, - 0.203]) were lower, in excess weight than normal weight adolescents. Excess weight adolescents seemed better at learning the most rewarding choices and showed a random strategy based on reward and novelty seeking. Consequently, excess weight adolescents made more disadvantageous selections, and performed worse in the IGT
Development of pathogenicity predictors specific for variants that do not comply with clinical guidelines for the use of computational evidence
Predictors de patogenicitat in silico; Variants missense; Seqüenciació de nova generacióPredictores de patogenicidad in silico; Variantes missense; Secuenciación de nueva generaciónIn silico pathogenicity predictors; Missense variants; Next-generation sequencingBackground
Strict guidelines delimit the use of computational information in the clinical setting, due to the still moderate accuracy of in silico tools. These guidelines indicate that several tools should always be used and that full coincidence between them is required if we want to consider their results as supporting evidence in medical decision processes. Application of this simple rule certainly decreases the error rate of in silico pathogenicity assignments. However, when predictors disagree this rule results in the rejection of potentially valuable information for a number of variants. In this work, we focus on these variants of the protein sequence and develop specific predictors to help improve the success rate of their annotation.
Results
We have used a set of 59,442 protein sequence variants (15,723 pathological and 43,719 neutral) from 228 proteins to identify those cases for which pathogenicity predictors disagree. We have repeated this process for all the possible combinations of five known methods (SIFT, PolyPhen-2, PON-P2, CADD and MutationTaster2). For each resulting subset we have trained a specific pathogenicity predictor. We find that these specific predictors are able to discriminate between neutral and pathogenic variants, with a success rate different from random. They tend to outperform the constitutive methods but this trend decreases as the performance of the constitutive predictor improves (e.g. with PON-P2 and PolyPhen-2). We also find that specific methods outperform standard consensus methods (Condel and CAROL).
Conclusion
Focusing development efforts on the case of variants for which known methods disagree we may obtain pathogenicity predictors with improved performances. Although we have not yet reached the success rate that allows the use of this computational evidence in a clinical setting, the simplicity of the approach indicates that more advanced methods may reach this goal in a close future.This work has been supported by the spanish Ministerio de Economía y Competitividad (BIO2012–40133; SAF2016–80255-R).

Análisis de la incidencia de la educación financiera y la competencia digital en la intención de emprendimiento de la población económicamente activa en la ciudad de Cuenca 2022
El emprendimiento, como un acto de innovación con la finalidad de producir riquezas,
surge de la necesidad de empleo y la escasez de ingresos. Por ello una parte de la economía
se ha dedicado a estudiar, sobre todo, tres constructos: la Intención de Emprendimiento (IE),
la Educación Financiera (EF) y la Competencia Digital (CD). El objetivo de este trabajo es
construir un modelo para determinar la relación de significancia entre estas variables en la
zona urbana de la ciudad de Cuenca. El estudio es de tipo correlacional, transversal con
enfoque cuantitativo, mediante el análisis factorial y el uso de ecuaciones estructurales a
partir de datos levantados a través de encuestas. La muestra examinada consta de 386
encuestas estratificadas en 15 parroquias urbanas de la ciudad. En los resultados más
destacados se encuentra la viabilidad del modelo, dado que el análisis incorpora a la CD
como variable mediadora de la relación con un efecto indirecto del 0,821. Además, se
agregan los resultados positivos y significativos entre la EF y la IE de 0,289. Se recomienda
a los emprendedores potenciar su conocimiento accediendo a programas públicos y privados
para incrementar las habilidades en estas áreas para dar lugar a la creación de nuevas unidades
de negocioEntrepreneurship, as an act of innovation to produce wealth, arises from the need for
employment and the scarcity of income. For this reason, a part of the economy has been
dedicated to studying, above all, three conduits: Entrepreneurship Intention (IE), Financial
Education (FE) and Digital Competence (DC). The purpose of this work is to build a model
to determine the significance relationship between these variables in the urban area of the
city of Cuenca. Th type of the study is correlational, cross-sectional with a quantitative
approach, through factor analysis and the use of structural equations from data collected
through surveys. The examined sample consists of 386 stratified surveys in 15 urban parishes
of the city. Among the most outstanding results is the viability of the model, given that the
analysis incorporates DC as a mediating variable of the relationship with an indirect effect
of 0.821. Furthermore, the positive and significant results between FE and IE of 0.289 are
added. It is recommended that entrepreneurs enhance their knowledge by accessing public
and private programs to increase skills in these areas in order to give rise to the creation of
business units.Ingeniero ComercialCuenc
Implementación de un sistema de gestión de inventarios para la localización de vehículos en los patios de almacenamiento de la Empresa CIAUTO Cía. Ltda.
El presente trabajo tuvo como objetivo implementar un Sistema de Gestión de Inventarios para la locación de vehículos en los patios de almacenamiento de la empresa CIAUTO CIA LTDA. Donde se desarrolló un método descriptivo debido a que de los valores de interés se fueron describiendo de manera significativa, donde se registraron las variables o se miden las mismas con la finalidad de definir las propiedades primordiales, en este caso a los automotores a almacenarse y se inició mediante la recolección de datos, mismo que fue de vital importancia para conocer la cantidad de automotores que se fabrican, y el error a permitirse debe ser el mínimo posible en caso de no poderse eliminar por completo, también se identificó el tipo de manejo de inventarios que se dispone, para a partir del mismo y de las necesidades de la empresa establecer una distribución de inventario de acuerdo a la metodología de calificación de inventarios ABC, definiendo que productos tienen una mayor demanda por parte de los clientes. Obteniendo como resultado que se han categorizado como clase A, B y C, mediante la distribución del mismo nombre y haberse determinado una proyección de la demanda para años posteriores que la demanda en el año 2022, para la marca Great Wall será de 4283 unidades, la marca DFSK de 2225 vehículos y la marca Shineray y Soueast tendrán un requerimiento de 2400 y 1872 automotores, dando un total de vehículos requeridos de 10780 en el año 2022. Concluyendo que la principal desventaja identificada dentro de la empresa CIAUTO CIA. LTDA es que no utilizan los patios de almacenamiento a su máxima capacidad. Se recomienda hacer uso adecuado de la aplicación web e instalar repetidores Wi-fi en los lugares más alejados de los patios de almacenamiento.The objective of this research was to implement an Inventory Management System for the location of vehicles in the storage yards of CIAUTO CIA LTDA, where a descriptive method was performed because the values of interest were described in a meaningful way, where the variables were registered or measured with the purpose of defining the primordial properties to the vehicles to be storaged and started with the data collection, which was essential to know the quantity of vehicles that are manufactured and the error to be allowed should be the minimum possible in case of not being able to be completely eliminated. It was also identified the type of inventory management that is available in order to establish an inventory distribution according to the ABC inventory qualification methodology, determining the products that have a higher demand from their customers. As a result, the products have been categorized as class A, B and C through the distribution of the same name and a demand projection has been determined for subsequent years. The demand in 2022 for the Great Wall brand will be 4283 units, the DFSK brand will have 2225 vehicles and the Shineray and Soueast brands will have a requirement of 2400 and 1872 vehicles, giving a total of 10,780 vehicles required in 2022. In conclusion, the main disadvantage identified within CIAUTO CIA. LTDA is that they do not use the storage yards to their maximum capacity and recommending making adequate use of the web application and install Wi-fi repeaters in the places farthest from the storage yards

Genomic determinants of organohalide-respiration in Geobacter lovleyi, an unusual member of the Geobacteraceae
Background
Geobacter lovleyi is a unique member of the Geobacteraceae because strains of this species share the ability to couple tetrachloroethene (PCE) reductive dechlorination to cis-1,2-dichloroethene (cis-DCE) with energy conservation and growth (i.e., organohalide respiration). Strain SZ also reduces U(VI) to U(IV) and contributes to uranium immobilization, making G. lovleyi relevant for bioremediation at sites impacted with chlorinated ethenes and radionuclides. G. lovleyi is the only fully sequenced representative of this distinct Geobacter clade, and comparative genome analyses identified genetic elements associated with organohalide respiration and elucidated genome features that distinguish strain SZ from other members of the Geobacteraceae. Results
Sequencing the G. lovleyi strain SZ genome revealed a 3.9 Mbp chromosome with 54.7% GC content (i.e., the percent of the total guanines (Gs) and cytosines (Cs) among the four bases within the genome), and average amino acid identities of 53–56% compared to other sequenced Geobacter spp. Sequencing also revealed the presence of a 77 kbp plasmid, pSZ77 (53.0% GC), with nearly half of its encoded genes corresponding to chromosomal homologs in other Geobacteraceae genomes. Among these chromosome-derived features, pSZ77 encodes 15 out of the 24 genes required for de novo cobalamin biosynthesis, a required cofactor for organohalide respiration. A plasmid with 99% sequence identity to pSZ77 was subsequently detected in the PCE-dechlorinating G. lovleyi strain KB-1 present in the PCE-to-ethene-dechlorinating consortium KB-1. Additional PCE-to-cis-DCE-dechlorinating G. lovleyi strains obtained from the PCE-contaminated Fort Lewis, WA, site did not carry a plasmid indicating that pSZ77 is not a requirement (marker) for PCE respiration within this species. Chromosomal genomic islands found within the G. lovleyi strain SZ genome encode two reductive dehalogenase (RDase) homologs and a putative conjugative pilus system. Despite the loss of many c-type cytochrome and oxidative-stress-responsive genes, strain SZ retained the majority of Geobacter core metabolic capabilities, including U(VI) respiration. Conclusions
Gene acquisitions have expanded strain SZ’s respiratory capabilities to include PCE and TCE as electron acceptors. Respiratory processes core to the Geobacter genus, such as metal reduction, were retained despite a substantially reduced number of c-type cytochrome genes. pSZ77 is stably maintained within its host strains SZ and KB-1, likely because the replicon carries essential genes including genes involved in cobalamin biosynthesis and possibly corrinoid transport. Lateral acquisition of the plasmid replicon and the RDase genomic island represent unique genome features of the PCE-respiring G. lovleyi strains SZ and KB-1, and at least the latter signifies adaptation to PCE contamination
