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.

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.

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.

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.

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.

Consumer value creation through clothing reuse: A mixed methods approach to determining influential factors
(2019)
Cruz Cárdenas, Jorge
;
Guadalupe-Lanas, Jorge
;
Velín-Fárez M.
Clothing reuse is a consumer disposal behavior that has been underexplored, although it has important consequences for the society. From the perspective of customer-dominant logic, reusing clothing is a consumer value creation behavior. To measure this tendency, we conducted a mixed method study in Ecuador, a developing Latin American country. We used 20 in-depth interviews followed by a survey of 425 adults to identify the factors associated with the tendency to reuse clothing. The study also identified gender differences regarding this behavior. Several factors in consumers' lives were revealed that explained the tendency to reuse clothing, including income, occupation, altruism, and physical environment. The study also showed that various population groups (e.g., lower income groups, younger individuals, students, and women) had a greater tendency to reuse clothing. © 2018 Elsevier Inc.

Dynamics of a Unicycle-Type Wheeled Mobile Manipulator Robot
(2020)
Varela Aldas, José
;
Chicaiza, F.A.
;
Andaluz V.H.
Mathematical modeling is widely used in robotics to display behaviors and design control algorithms; the dynamic model of a robot describes the movements considering the action of internal and external forces of the system. This paper presents the dynamics of a unicycle mobile manipulator robot using the Euler-Lagrange proposal and conditioning the model to obtain the output velocities in the robot from the desired velocities. Additionally, the dynamic model is complemented by the identification of parameters using experimental data obtained from the AKASHA robot. The results present the signals applied in the identification, the values of the dynamic constants are found and the validation data which indicate a correct performance of the proposal are graphically shown. © 2020, Springer Nature Switzerland AG.

The educational disorders that children present at an early age can cause them to not fully develop throughout their lives. In this research work a 3D virtual system that allows the child who has been diagnosed with dyslexia to complement the exercises performed in a conventional therapy is described. To achieve this an application was developed, the app consists of two games (each with three levels of difficulty), and that are part of the rehabilitation program. In each of these games virtual objects are combined with auditory messages to provide the user with an immersive experience, and to train more than one sense at a time. In the first game task, the activity asks the children to correctly locate the syllables that compose a word and for the second activity the children will listen to a word, after the games asks the children to select the correct word. This tool has been tested by a group of children (eight), with ages ranging from 8 to 12 years old, whose development can be supervised at home by their parents, since it is an intuitive and easy to use interface. The results obtained are stored in a database and in this way the medical specialist can monitor the progress of the child throughout his treatment. For the validation of this proposal the SUS usability test was used. © Springer Nature Switzerland AG 2020.

Global fern and lycophyte richness explained: How regional and local factors shape plot richness
(2020)

Aim: To disentangle the influence of environmental factors at different spatial grains (regional and local) on fern and lycophyte species richness and to ask how regional and plot-level richness are related to each other. Location: Global. Taxon: Ferns and lycophytes. Methods: We explored fern and lycophyte species richness at two spatial grains, regional (hexagonal grid cells of 7,666 km2) and plot level (300–500 m2), in relation to environmental data at regional and local grains (the 7,666 km2 hexagonal grid cells and 4 km2 square grid cells, respectively). For the regional grain, we obtained species richness data for 1,243 spatial units and used them together with climatic and topographical predictors to model global fern richness. For the plot-level grain, we collated a global dataset of nearly 83,000 vegetation plots with a surface area in the range 300–500 m2 in which all fern and lycophyte species had been counted. We used structural equation modelling to identify which regional and local factors have the biggest effect on plot-level fern and lycophyte species richness worldwide. We investigate how plot-level richness is related to modelled regional richness at the plot's location. Results: Plot-level fern and lycophyte species richness were best explained by models allowing a link between regional environment and plot-level richness. A link between regional richness and plot-level richness was essential, as models without it were rejected, while models without the regional environment-plot-level richness link were still valid but had a worse goodness-of-fit value. Plot-level richness showed a hump-shaped relationship with regional richness. Main conclusions: Regional environment and regional fern and lycophyte species richness each are important determinants of plot-level richness, and the inclusion of one does not substitute the inclusion of the other. Plot-level richness increases with regional richness until a saturation point is reached, after which plot-level richness decreases despite increasing regional richness, possibly reflecting species interactions. © 2019 John Wiley & Sons Ltd
