Spatial distribution patterns of fish assemblages relative to macroinvertebrates and environmental conditions in Andean piedmont streams of the Colombian Amazon

2016 , Tobes I. , Gaspar S. , Peláez-Rodríguez M. , Miranda R.

This work provides insight into an Andean–Amazonian river system by conducting a comprehensive study of the biodiversity and ecological processes in a poorly studied neotropical freshwater ecosystem. Hacha River in western Colombia harbours a rich and largely unknown biodiversity and is experiencing an increase in anthropogenic impacts from the city of Florencia. Changes in natural habitat characteristics and environmental quality were analysed and related to the distribution of fish and macroinvertebrates. Four environmental quality indices were applied, and concentrations of potential water pollutants were measured. All environmental quality indices used were reliable because they produced similar assessments of the ecological integrity of the study sites and were inversely related to the potential water pollutant concentrations. Fish and macroinvertebrate communities notably changed in response to differences in environmental quality, reinforcing the ecological integrity assessments. Nevertheless, natural gradients that influence fish and macroinvertebrate distributions showed an overlap with changes in environmental quality, thereby confounding the ability to discern the influence of natural and anthropogenic-induced alterations and to confirm an initials hift in fish assemblages due to anthropogenic impacts. © International Society of Limnology 2016.

Patterns of timber harvesting and its relationship with sustainable forest management in the western Amazon, Ecuador case

2017 , Bonilla Bedoya, Santiago , Estrella-Bastidas A. , Ordoñez M. , Sánchez A. , Herrera M.A.

The Amazon rainforest lies within the most diverse forest ecosystem in the world. However, a large part of the tropical rainforest is being degraded because of timber harvesting without any sustainability criteria and owing to a limited understanding of the effects of forest exploitation. The Ecuadorian Amazon (EA) is part of the Andes Amazon (AA), an area covered by five countries (Venezuela, Colombia, Ecuador, Peru and Bolivia). This research identified the patterns of legal timber harvesting in the EA and determined current trends with respect to mostly harvested forest species. Two harvesting programs aimed at small farmers prevail in the EA: first, naturally regenerated trees felling program, and simplified timber harvesting programs in native forests. Considering the surface and volume of logging, significant differences were detected between logging procedures and ecosystems in the region. Two hundred and thirty-two genera are registered for harvest and, 51.93% of the total harvesting volume comes from eight genera and ten species. This research shows that in fallows of fragmented forest ecosystems, small farmers are harvesting fast-growing pioneer species. Maintaining a sustainable production in timber harvesting depends, by and large, on the harvesting and felling programs established on small farms. © 2017 Taylor & Francis.

Challenges of Migrating Legacies Web to Mobile: A Systematic Literature Review

2020 , Cajas Cajas, Viviana Elizabeth , Urbieta M. , Rossi G. , Dominguez Mayo F.

The multi-device era comes thanks to mobile computing which gives remote access to resources from anywhere changing the people's life and opening new business opportunities. However, the legacy systems do not render the content properly in mobile devices because they were thought to be only compliant with Web browsers. Economic availability is often the reason why these have not been modernized. This work proposes a systematic literature review about the approaches used for the portabilization or modernization of web 1.0 business applications to mobile devices in the period 2006-2017, from SCOPUS, IEEE, and ACM. The search obtained 824 articles, 44 were selected and classified with respect to focus, scope, type of research and type of contribution. The results obtained allowed us to reach conclusions about the state of the subject and to determine the research gaps, such as the need for better use of the mobile characteristics because the adaptations are mostly basic. In addition, an approach is proposed and compared with the aforementioned them. © 2003-2012 IEEE.

Digital Divide: A Bibliometric Approach to Existing Knowledge

2023 , Cruz Cárdenas, Jorge , Palacio Fierro, Andrés , Zabelina E. , Deyneka O. , Ramos Galarza, Carlos

The topic of digital divide - the gap between those who have and those who do not have access to digital technologies - is of growing interest for both public and private sectors. This interest is reflected in an increasing number of academic and scientific publications focused on the topic. This study presents an overview of the digital divide research using a bibliometric approach. Analyzing 9,523 documents from the Scopus database, this study found that 1) there has been an accelerated growth in the publication rate on digital divide since 2018; 2) digital divide is a multidisciplinary field, led by the United States and other developed countries and some emerging countries; 3) the dominant term used to refer to the field, as per our analysis of the relevant keywords, is "digital divide"; and 4) as per our analysis of the evolution of keywords' importance, while topics related to technologies were of interest several years ago, current interest revolves around the effects of the Covid-19 pandemic, the elderly, education, and healthcare access. © 2023 IEEE.

GENDER EQUALITY IN INTERNATIONAL LABOR STANDARDS AND FAIR RECRUITMENT

2023 , Pangol Lascano, Alberto , Romero Carrera E.C.

At the global level, the universalization of labor rights is in a stage of profound transformation, aimed at strengthening protective mechanisms. The States have committed to propose responses to all these challenges with multidimensional criteria and framed in the fulfillment of fundamental rights. This is how the ILO through the NIT includes principles and rights at work as enabling conditions that contribute to a better life condition of society. In this context, this research aims to analyze gender equality in international labor standards and fair hiring, through a legal-comparative analysis, responding to a qualitative research approach. The results made it possible to show that, although international labor standards have not been fully integrated into national legislation, which violates the principle of gender equality, since women continue to be discriminated against in terms of employment and occupation. In addition, globalization has affected the migration of workers, which is why the fair hiring process arises, promoted by the ILO, and whose initiative is to prevent abuses of workers, human trafficking and forced labor. © 2023, University of Cienfuegos, Carlos Rafael Rodriguez.

Mobile Manipulator for Hospital Care Using Firebase

2022 , Varela Aldas, José , Buele, Jorge , Guerrero-Núñez S , Andaluz V.H.

The COVID-19 pandemic has shown that the use of the technology in medicine is no longer a luxury, but a necessity. The use of the robotics in the treatment of diseases and physical therapies is limited in Latin America due to the high acquisition and maintenance costs. This document proposes the design, development, and evaluation of a robotic system for the guided monitoring of patients, through remote control using a mobile application. Within the methodology, four phases were proposed: planning, design, development, and evaluation. The 3D design is done using the Tinkercad software, which facilitates the construction of the pieces using 3D printing technology. The ESP32 board is the main element that receives the signals from the sensors and controls the actions of the actuators through the orders received from Firebase. For the development of the application, App inventor is used, building a friendly and easy-to-use interface. To validate this proposal, experimental tests were carried out with two patients in a medical center. In addition, a parameter compliance questionnaire was applied to the robot, obtaining a score of 92.6%, and the mobile application obtained 72.5% in the usability test. All this confirms an efficient care proposal, with a reduced investment. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
