The digitalization of recruitment processes has paved the way for the integration of artificial intelligence (AI) into hiring, transforming how organizations identify and select talent. According to a McKinsey [7] report, the use of AI has significantly reduced hiring times by automating résumé screening and candidate preselection. However, a key question arises: does this efficiency also translate into better candidate quality, reflected in performance and retention rates? This study seeks to answer the following question: how does the use of AI systems in résumé analysis impact the reduction of recruitment time and the improvement of candidate quality, as measured by the retention rate after two months? The main objective is to evaluate how the implementation of AI in selection processes influences both the speed and quality of hiring. This research is relevant because it provides empirical evidence about the benefits and limitations of AI in recruitment, allowing organizations to make more informed decisions regarding its adoption. A literature review was conducted to explore the topic from different perspectives. Preliminary findings indicate that AI can streamline processes, improve selection accuracy, and reduce bias, although concerns remain regarding algorithmic transparency and fairness. The study adopts a mixed-methods approach: in the quantitative phase, traditional and automated processes are compared in résumé analysis, psychometric testing, and interviews, measuring hiring times and retention rates. In the qualitative phase, recruiters were surveyed to gather their perceptions about the use of AI in decision-making. Preliminary results suggest a significant reduction in hiring times but similar retention rates between traditional and AI-assisted methods. Consequently, a hybrid recruitment model is proposed, in which the synergy between humans and intelligent systems strengthens decision-making, promoting more efficient, transparent, and equitable selection processes. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.

Health information on the Web can make patients better informed about a disease, which according to several studies leads to better treatment results. However, the health information found on the Web is not accessible because it presents barriers that prevent people from easily accessing it because it does not comply with the standards of the Web Content Accessibility Guidelines (WCAG) 2.1. Therefore, in this study, we present an analysis of the accessibility of the seven most visited health websites in the world. To analyze the accessibility of medical websites, we apply an automatic review method. The results show that health websites have frequent problems related to the lack of alternative text, empty links, and contrast errors. This research can contribute to future work related to accessibility in health and medical sites. Finally, we suggest designing a combined method to review each website’s accessibility barriers to complement the automatic review. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

This work proposes a model of movement detection in patients with hip surgery rehabilitation. Using the Microsoft Xbox One Kinect motion capture device, information is acquired from 25 body points -with their respective coordinate axes- of patients while doing rehabilitation exercises. Bayesian networks and sUpervised Classification System (UCS) techniques have been jointly applied to identify correct and incorrect movements. The proposed system generates a multivalent logical model, which allows the simultaneous representation of the exercises performed by patients with good precision. It can be a helpful tool to guide rehabilitation. © 2019, Springer International Publishing AG, part of Springer Nature.

Web accessibility is increasingly recognized as a key factor in assessing higher education institutions’ quality, inclusion, and social responsibility. This topic is particularly relevant in Latin America, where significant disparities in digital equity and access to resources persist. This study analyzes the web accessibility of the top 20 Latin American universities based on their rankings in QS World University Rankings, Webometrics, SCImago Institutions Rankings, and Times Higher Education (THE). Using automated and manual assessment tools, including WAVE, PageSpeed Insights, and expert assessments, the study identifies 434 contrast errors, 210 missing text alternatives, and 262 navigation issues on university websites. The results show that universities such as USP, UNAM, and Unicamp rank high in international rankings but have critical accessibility deficiencies, highlighting the gap between digital visibility and inclusion. By aligning with WCAG 2.2 and the Sustainable Development Goals (SDGs), in particular SDG 4 (Quality Education), SDG 9 (Industry and Innovation), and SDG 10 (Reduced Inequalities), universities can improve global competitiveness while fostering digital inclusion. This research proposes a structured framework to promote accessibility through a seven-phase methodology, addressing barriers, implementing improvements, and validating effectiveness. The findings provide a systematic approach for universities to optimize accessibility, improve user experience, and strengthen their international positioning

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.

This paper explains some of the challenges that exist to make accessible the web interfaces of a Tele-rehabilitation platform for hip arthroplasty patients and propose an iterative method to improve the level of accessibility using automatic evaluation tools. Web accessibility is not concerned with the specific conditions of people who use the Web, but with the impact that their conditions have on their ability to use it. If the web interfaces of the Tele-rehabilitation platform for hip arthroplasty patients are not accessible enough, the patients will not be able to understand, perceive or operate adequately the platform to benefit completely of the physical therapy. The Web Content Accessibility Guidelines (WCAG 2.0) provides a set of rules and recommendations to help solve the problems of Web accessibility. Additionally, there are evaluation tools that allow identifying main web accessibility problems. These tools are best exploited when used by accessibility experts. The purpose of this research is threefold. First, to present the results of a web accessibility evaluation of the web interfaces of the Tele-rehabilitation Platform for Hip Arthroplasty Patients using three the evaluation tools: WAVE, AChecker and TAW. Second, to analyze the results presented by the tools according to the WCAG 2.0 guidelines to define a list of accessibility improvements. Third, to implement the improvements through the re-factorization of the existing code and re-testing the improved web interfaces to verify that they meet acceptable accessibility levels. © Springer International Publishing AG, part of Springer Nature 2019.

This study addresses the optimization of quality management in health insurance to achieve sustainable cost reduction while maintaining service standards. Utilizing a mixed-methods approach, the research combines literature review and survey data to analyze user perceptions of service quality and the role of digital technologies. The survey included a diverse sample of health insurance users, capturing insights on satisfaction, technological tools, and quality management processes. Key findings reveal that user satisfaction is significantly influenced by transparency, accessibility, and the integration of digital tools such as mobile apps, web portals, CRM systems, and telemedicine. Correlation analyses showed a moderate positive relationship between the frequency of technology usage and perceived effectiveness, satisfaction, and future impact expectations. Despite moderate satisfaction levels with current technologies, participants emphasized the need for advanced tools to enhance efficiency and user experience. Demographic analysis indicated that educational level positively correlated with satisfaction, highlighting the importance of user training for technology adoption. Additionally, older users reported lower satisfaction, signaling the need for more inclusive and user-friendly systems. Gender differences in satisfaction and the positive association between customer loyalty and perceived service quality further underscore the importance of personalized strategies. The study concludes that digital transformation in health insurance can sustainably reduce costs while meeting user expectations. Key recommendations include increasing user education, investing in advanced technologies, and tailoring solutions to diverse demographic needs. These findings provide actionable insights for insurance companies aiming to improve operational efficiency and enhance service quality sustainably.

This article reports a study in which three experimental tasks (SIMON, Go / No-Go and Stroop Victoria) were adapted and validated to evaluate the inhibitory control and interference control in a sample of Ecuadorian students. The sample consisted of 100 students between 6 and 15 years old (M = 10.13 years, SD = 2.48) belonging to the public education system of Ecuador. The process followed in the adaptation and validation was through the linguistic translation of the experiments, followed by an expert judgment and a pilot study. In the results it was found that there are no statistically significant differences in the measures that assess the inhibitory control and the interference considering the sociodemographic variables of the participants as comparison factors. In the correlation analysis we found a statistically significant association between the measurements of the experiments. We conclude by analyzing the associations found and underlining the need to continue providing evidence in the research line of adaptation and validation of test for using in neuropsychological evaluation.
