Surveillance Routing of COVID-19 Infection Spread Using an Intelligent Infectious Diseases Algorithm
(2020)
Guevara Maldonado, César Byron
;
Penas M.S.
In this study, the Intelligent Infectious Diseases Algorithm (IIDA) has been developed to locate the sources of infection and survival rate of coronavirus disease 2019 (COVID-19), in order to propose health care routes for population affected by COVID-19. The main goal of this computational algorithm is to reduce the spread of the virus and decrease the number of infected people. To do so, health care routes are generated according to the priority of certain population groups. The algorithm was applied to New York state data. Based on infection rates and reported deaths, hot spots were determined by applying the kernel density estimation (KDE) to the groups that have been previously obtained using a clustering algorithm together with the elbow method. For each cluster, the survival rate - the key information to prioritize medical care - was determined using the proportional hazards model. Finally, ant colony optimization (ACO) and the traveling salesman problem (TSP) optimization algorithms were applied to identify the optimal route to the closest hospital. The results obtained efficiently covered the points with the highest concentration of COVID-19 cases. In this way, its spread can be prevented and health resources optimized. © 2013 IEEE.

Premise of research. Heterospecific pollen deposition on stigmas can impact plant reproduction by decreasing seed set or inducing fruit abortion. Pollinating bats often carry pollen from many species on their fur, and thus bat-pollinated flowers may exhibit tolerance to heterospecific pollen deposition, but to our knowledge this has never been studied. We investigated the relative impact of increasing heterospecific pollen deposition on female reproduction of two sympatric species of Burmeistera that experience pollen transfer between them by their shared bat pollinators. Methodology. We simulated heterospecific pollen deposition by applying pollen mixtures that differed in the ratio of heterospecific to conspecific flowers used to make them (3∶1; 2∶2, and 1∶3) and measured female reproduction by quantifying fruit abortion, seed number, and seed mass. Pivotal results. For Burmeistera borjensis, applying a higher relative amount of heterospecific pollen led to decreased seed production and lighter seed mass, whereas no significant effect of increasing heterospecific pollen was detected in Burmeistera ceratocarpa. Burmeistera borjensis aborted more fruits than B. ceratocarpa (44.1% vs. 18.8%); however, in both species the probability of fruit abortion was not affected by pollination treatment. Conclusions. We detected asymmetric impacts on female reproduction between this pair of sympatric Burmeistera: while increasing heterospecific pollen deposition decreased seed production and seed mass for B. borjensis, it had no detectable effect on B. ceratocarpa. Prior work shows that in nature B. borjensis receives much lower amounts of heterospecific pollen than B. ceratocarpa, and thus results suggest that B. ceratocarpa may have stronger gametic or postzygotic isolating barriers to be able to tolerate heterospecific pollen deposition. Future work should explore how different isolation mechanisms contribute to the asymmetric effects on female reproduction that we report here and whether tolerance to heterospecific pollen deposition is a common response among bat-pollinated plants and other plant taxa relying on low-fidelity pollinators. © 2019 by The University of Chicago.

Corporate veil in the execution of the labor obligationsthe [El velo societario en la ejecución de obligaciones laborales]
(2021)
Holguin E.P.H.
;
Lascano A.M.P.
The doctrine of the lifting of the corporate veil was created precisely to prevent abuses in the use of legal status, and consti-tutes a way that allows creditors to penetrate the patrimony of the partner or shareholder. The objective of this research is: To establish a reflective, critical and legal analysis of the legislation applicable to the lifting of the corporate veil for the execution of work-related sentences in Ecuador. The methodology that was applied was Historical-Legal-descriptive, because it allowed the historical monitoring of the subject of study and through the application of the analytical method. An important fin-ding of this work has been the analysis of cases, where the rights of workers, despite being recognized under a court ruling, cannot be fully enforced, due to having preceded fraudulent maneuvers by members of the legal entity that have simulated legal acts, to hide the assets of the companies and leave the workers unprotected. As a conclusion of the breaking of the hermeticism of the legal entity, it seeks to protect the rights of creditors, with the application of procedural actions regulated by law, and to link unpaid obligations to the assets of natural persons behind the corporate facade. © 2021, University of Cienfuegos, Carlos Rafael Rodriguez.

The research develops an industrial software application called FAPS System for the planning and scheduling manufacturing. It contains three modules used for planning and programming of resources, process management and Andon module focused on the use of lean manufacturing techniques for the notification, emission and display of contingencies presented during the production in real time. A case study is described in Ecuadorian footwear companies for the execution of experimental prototype efficiency tests. Through the unified modeling language diagrams, the requirements and functionalities of the software developed based on private and free technologies are defined. The planning module has a scheduling algorithm of days based on weighted standards that allows to estimate the delivery date of a production order, reprogram it and compare the planned quantity with respect to the capacity used. The Andon module is an Android application that consumes the information managed in the planning and process modules, thereby monitoring in real time the state of the plant and the production progress. The experimental results show that the system is adaptable to multiproduct orders and the scheduling allows to increase 6% the utilization percentage of the production processes.

This work presents the kinematic and dynamic modeling of a humanwheelchair system where it is considered that its mass center is not located at the wheels’ axis center of the wheelchair. Furthermore, it is presents a new motion controller for human-wheelchair system that is capable of performing positioning and path-following tasks. The proposed controller has the advantage of simultaneously performing the approximation of the robot to the proposed path by the shortest route and limiting its velocity. This controller design is based on two cascaded subsystems: a kinematic controller with command saturation, and a dynamic controller that compensates the dynamics of the robot. © Springer International Publishing Switzerland 2015.

Social construction of violence in adolescents victims of trafficking for criminal purposes [Construcción social de la violencia en adolescentes víctimas de trata con fines delictivos]
(2017)
Montero Medina D.C.
;
Subía Arellano A.F.
;
Calvo Rodríguez M.M.
This qualitative work aimed to understand the social construction of violence in adolescents victims of trafficking for criminal purposes. Four life histories were made, which were analyzed through the dialectical hermeneutic method. The results show three main categories related to social history, family history and personal history. Adolescents have been participants in a violent social and family context, child labor, family violence, socioeconomic precariousness and gender violence, so that the social construction of violence is a determining factor in vulnerability to trafficking. © 2017, Universidad del Zulia.

Mobile instant messaging (MIM) is one of the most influential technologies in society today due to its wide penetration in the world’s population. The present study aims to establish whether two consumer traits, extraversion and novelty seeking, have the potential to explain the intensity of MIM usage by consumers considering its good performance in explaining other consumer behaviors. The present study is based on a survey of 682 adults in Quito, the capital of Ecuador, which is a South American developing country. The data obtained are analyzed with structural equation modeling and establish that while extraversion is not related to the intensity of MIM use, novelty seeking does have a direct and positive effect. This study makes recommendations for business theory and practice. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

For several years now, several computational processes have been investigated in conjunction with the new techniques of artificial intelligence, data mining and the use of algorithms that are in line with the classification of data that they have contributed in other contexts such as The case in the areas of medicine especially in neurological diseases such as Alzheimer's, Parkinson's and Huntington's for this case was the study of Alzheimer's disease that affects the elderly in their cognitive and behavioral functions, the objective of this research is oriented to manipulate existing data of the disease supported by the use of the negative selection algorithm that is part of a classification of the context of genetic algorithms, classification techniques use decision trees, Naive Bayes, System Networks Neuronal Supervised Classifier and, the decision trees represent the decisions of the In the data, naive bayes is exclusive of a probabilistic context, the neural network that is based on an environment of the biological model, UCS is identified in a type of rules of a condition and action. The results have been from the origin of data from a patient population of 499 original instances and 1001 generated by means of the negative selection algorithm, the detection rate and the false alarm rate after the mathematical process justifies the validity of the data evidencing the way in which the data have been properly manipulated and verified, finally it is concluded that this type of algorithms is the case of negative selection and also in applications with conditions similar to neurological contexts as in the case of this investigation. It can also be stated that the classification techniques and their applicability make it possible to determine the use of metaclassifiers that are subject to the identification and verification of the results of the research carried out. © 2018 AISTI.

Male principal investigators (almost) don’t publish with women in ecology and zoology
(2019)

Representation of women in science drops substantially at each career stage, from early student to senior investigator. Disparities in opportunities for women to contribute to research metrics, such as distinguished speaker events and authorship, have been reported in many fields in the U.S.A. and Europe. However, whether female representation in scientific contributions differs in other regions, such as Latin America, is not well understood. In this study, in order to determine whether female authorship is influenced by gender or institutional location of the last (senior) author or by subfield within ecology, we gathered author information from 6849 articles in ten ecological and zoological journals that publish research articles either in or out of Latin America. We found that female authorship has risen marginally since 2002 (27 to 31%), and varies among Latin American countries, but not between Latin America and other regions. Last author gender predicted female co-authorship across all journals and regions, as research groups led by women published with over 60% female co-authors whereas those led by men published with less than 20% female co-authors. Our findings suggest that implicit biases and stereotype threats that women face in male-led laboratories could be sources of female withdrawal and leaky pipelines in ecology and zoology. Accordingly, we encourage every PI to self-evaluate their lifetime percentage of female coauthors. Female role models and cultural shifts–especially by male senior authors–are crucial for female retention and unbiased participation in science. © 2019 Salerno et al.

Q’inqu: Inclusive Board Game for the Integration of People with Disabilities
(2020)
Jadán Guerrero, Janio

The educational inclusion of people with disabilities continues to be a great challenge for society. Due to the field’s diversity and complexity, people with disabilities have few opportunities to be integrated into educational activities or even entertainment. This article describes a novel educational resource developed within the field of applied technologies. Q’inqu is an inclusive board game that encourages the family and educational inclusion of people with disabilities. Q’inqu is a Quechua word meaning “Labyrinth”. This is a metaphor for the challenges faced by families living with a person with disabilities, and it also reflects its narrative structure based on the “Legend of the Incas’ treasure”. Q’inqu has the general theme of a traditional board game where turns are taken until the treasure is found. What makes it different is the integration of inclusive elements through the use of technology. There are cards with a braille code, a rectangular board with high relief, and a circular board with textures. An App reads QR codes and also patterns, which present additional information based on augmented reality. These features provide support to blind players and to those who are unable to read, making the game both entertaining and educational. Q’inqu was developed and tested by a multidisciplinary team of 80 people, which included students and professionals from design, education and pedagogy. The most relevant result was that out of 367 ideas that were presented, it was awarded first prize in the category Toys for children with disabilities in the CMA contest held in Ecuador. © 2020, Springer Nature Switzerland AG.
