2020 , Ortiz-Granja D. , Acosta-Rodas P. , Lepe-Martínez N. , Valle M.D. , Ramos V. , Pasquel M.B. , Ramos Galarza, Carlos

Assessment of the adult attachment in the Latin American context as a research line is not yet solved. This study has the aim to present the results of the development and validation of a scale to assess the adult attachment. The sample was composed of 1563 participants aged between 17 and 33 years from Chile and Ecuador. This scale was formed by 14 items, which allowed the assessment of secure attachment, avoidant attachment, and ambivalent attachment. Results are as following: (a) the scale presented an adequate internal consistency for secure attachment α=.73 and ω=.82, avoidant α=.58 and ω=.70, and ambivalent α=.69 and ω=.73; (b) adequate convergent validity with sense of coherence (r=.34 and .43, p=< .001); (c) the exploratory factor analysis kept up the items’ organization developed KMO=.77, x2=4133.91, p=<.001; and, (d) the confirmatory factor analysis presented a good fit with three items for each attachment type x2(24)=136.28, p=<.001, CFI=.95, RMSEA=.05(.04–.06), SRMR=.03. Findings of psychometric properties are discussed, highlighting the contribution of this scale in the Latin American context and its relationship with previous research. © 2020 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

Factorial Structure of the EOCL-1 Scale to Assess Executive Functions

2021 , Ramos Galarza, Carlos , Cruz Cárdenas, Jorge , Bolaños-Pasquel M. , Acosta-Rodas P.

The process of assessing executive functions through behavioral observation scales is still under theoretical and empirical construction. This article reports on the analysis of the factorial structure of the EOCL-1 scale that assesses executive functions, as proposed by the theory developed by Luria, which has not been previously considered in this type of evaluation. In this scale, the executive functions taken into account are error correction, internal behavioral and cognition regulatory language, limbic system conscious regulation, decision making, future consideration of consequences of actions, goal-directed behavior, inhibitory control of automatic responses, creation of new behavioral repertoires, and cognitive–behavioral activity verification. A variety of validity and reliability analyses were carried out, with the following results: (a) an adequate internal consistency level of executive functions between α = 0.70 and α = 0.83, (b) significant convergent validity with a scale that assesses frontal deficits between r = −0.07 and r = 0.28, and (c) the scale’s construct validity that proposes a model with an executive central factor comparative fit index (CFI) = 0.93, root mean square error of approximation (RMSEA) = 0.04 (LO.04 and HI.04), standardized root mean square residual (SRMR) = 0.04, and x2(312) = 789.29, p = 0.001. The findings are discussed based on previous literature reports and in terms of the benefits of using a scale to assess the proposed executive functions. © Copyright © 2021 Ramos-Galarza, Cruz-Cárdenas, Bolaños-Pasquel and Acosta-Rodas.

From Face-to-Face Learning to Virtual Learning: Students’ Perspective

2023 , Cóndor-Herrera, Omar , Bolaños-Pasquel, Mónica , Ramos Galarza, Carlos , Cruz Cárdenas, Jorge

This article reports the results found in an investigation which analyzed the perception that students have regarding the virtual learning process developed during the COVID-19 pandemic. The study involved 38 students from a Latin American institution whose age ranged from 13 to 15 years of age, who carried out their academic activities virtually for a school year, once the school period ended, a survey was applied to collect information on the experience in virtual classes, once the results have been analyzed, it is evident that the vast majority of students issued responses in favor of virtual teaching and that virtual classes served to develop their skills in managing technological resources, on the other hand a number of participants They did not indicate the learning experience as positive or negative. This may be related to the fact that a group of participants did not have good quality internet. In the same way, the results reflect that the students consider that not having adequate equipment and good quality internet quality are a limitation in the learning process virtual lift. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Organizational Culture and Digital Transformation: A Bibliometric Approach

2022 , Cruz Cárdenas, Jorge , Parra-Domínguez J. , Zabelina E. , Deyneka O. , Ramos Galarza, Carlos

Organizational culture is a key to the success of business digital-transformation initiatives. The current study presents a bibliometric approach to the current knowledge of culture and digital transformation. For this purpose, 407 relevant documents were analyzed. The descriptive analysis indicated a panorama of great growth in the literature. An analysis of word co-occurrence in titles and abstracts was used to identify four areas of research interest: (1) training and learning among personnel, (2) cultural values that underpin the digital transformation, (3) environmental influences, and (4) technologies that enable digital transformation. Finally, little international collaboration between author networks was found. © 2022 IEEE.

Introduction: The symbol digit modality test is a reactive which provides great support in neuropsychological evaluation. Its execution permits to evaluate brain functions such as visual perception, stimuli recognition, attention (focal, selective and sustained), task supervision, interference control among others. Object: The purpose of the current research study was to analyze the normative percentiles of the execution of the test, to identify the performance activity of the reactive according to age group and gender; applying the test in a sample of college students. Method: The sample included 250 university students,142 (56.8%) males and 108 (43.2%) females. The age range of the participants was between 18 and 34 years old (M=21.53, DE=2.25). A transversal, non-experimental, quantitative research model with a correlational scope was used. Results: The correct answer average for the test was 52.83 (DE=13,60) and for percentile P5 31,55 right answers were found; for percentile P75 60,00 right answers, P25 had 46,00 right answers, and for P95 74,45 right answers were found. No significant differences were found for the mean of errors in the test in terms of age group f(3, 246)=0,67, p=0,57 and gender t(248)=0,68, p=0,49 of the participants as comparison factor. Conclusions: Results were discussed based on prior research pointing out the importance of counting with a first statistical parameter of the test as ground for neuropsychological clinical practice in Ecuador. © 2018 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

Low-Cost Human–Machine Interface for Computer Control with Facial Landmark Detection and Voice Commands

2022 , Ramos, P. , Zapata, Mireya , Valencia, K. , Vargas, V. , Ramos Galarza, Carlos

Nowadays, daily life involves the extensive use of computers, since human beings are immersed in a technological society. Therefore, it is mandatory to interact with computers, which represents a true disadvantage for people with upper limb disabilities. In this context, this work aims to develop an interface for emulating mouse and keyboard functions (EMKEY) by applying concepts of artificial vision and voice recognition to replace the use of hands. Pointer control is achieved by head movement, whereas voice recognition is used to perform interface functionalities, including speech-to-text transcription. To evaluate the interface’s usability and usefulness, two studies were carried out. The first study was performed with 30 participants without physical disabilities. Throughout this study, there were significant correlations found between the emulator’s usability and aspects such as adaptability, execution time, and the participant’s age. In the second study, the use of the emulator was analyzed by four participants with motor disabilities. It was found that the interface was best used by the participant with cerebral palsy, followed by the participants with upper limb paralysis, spina bifida, and muscular dystrophy. In general, the results show that the proposed interface is easy to use, practical, fairly accurate, and works on a wide range of computers. © 2022 by the authors.
