Ítem Decent work and healthy employment: a qualitative case study about Colombian millennials(Emerald Group Publishing Ltd., 2020-01-01) Gallo Ó.; Gonzales–Miranda D.R.; Roman-Calderon J.P.; García G.A.Purpose: The purpose of this article is to show how a group of Colombian millennials perceive different aspects of working life and how their ideas about job satisfaction, professional expectations and levels of autonomy are related to contemporary demands about inclusion, diversity, equity, autonomy and control. Design/methodology/approach: With this objective, 167 semi-structured interviews were conducted with millennials who work at 10 Colombian companies from the manufacturing and service sectors, located in the five main cities of the country. With a qualitative approach, in the interviews, the research team used a strategy inspired by the technique of generating visual structures associated with grounded theory. Findings: It is concluded that new generations of Colombian workers know of the importance of rewards and autonomy in work and are more critical and less passive in the face of unhealthy working conditions. At the same time, their conduct and speeches are the consequence of the characteristics of the Colombian labour market. The document responds to the need to deepen the debates on welfare and happiness in organizations and to include the demands of millennials in the reflective and political horizon of the ideas of healthy employment and decent work. In practice, this article seeks to demystify ideas about millennials in Colombia and critically contribute to reflection on intergenerational relations in organizations and salary and welfare models. As a Latin American case, it is an original contribution that avoids the common places and the frivolity with which the insertion of the new generations into the working world has been analysed. Practical implications: In practice, this paper seeks to demystify ideas about millennials in Colombia and critically contribute to reflection on intergenerational relations in organizations and salary and welfare models. Originality/value: As a Latin American case, it is an original contribution that avoids the common places and the frivolity with which the insertion of the new generations into the working world has been analysed. © 2020, Emerald Publishing Limited.Ítem Design and implementation of a low-cost projected virtual reality system to support learning processes(Springer Verlag, 2011-01-01) Gómez, R.; Trefftz, H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesVirtual Reality technologies have been successfully incorporated into the learning processes and potential new applications in education are explored continuously. We found that one of the difficulties to popularize its use in the educational context, in countries with emerging and developing economies, is the cost of hardware required to generate satisfactory immersive experience. In this work we considered virtual reality from the perspective of human-computer interaction to support learning processes. The characteristics of low-cost projected virtual reality system (PVR) proposed, combines study and integration of available technology solutions, the development of an image synchronization routine that enables the use of a single video projector and the design of a printable pattern that preserve the state of polarization on the projection screen. © 2011 Springer-Verlag.Ítem Design and usability evaluation of a multi-input interface in an idTV environment(Springer Verlag, 2017-01-01) Téllez J.F.; Montoya J.C.; Trefftz H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesIn recent years, and considering the rise of Interactive Digital Television (idTV), it has been great interest in the design of applications and services for this platform. However, the success of these applications largely depends on the ease of use and how users interact with them. For this reason, we have explored different interfaces and modes of interaction to improve the user experience with these applications in comparison with the traditional Remote-Control (RC). This article presents an interaction with idTV applications using multiple input control interfaces with different modes of interaction such as touch buttons, gesture recognition, voice recognition, and recognition of movements. These modes of interaction were validated through usability testing using a model of quasi-experimental evaluation of three dimensions, where each dimension represents respectively: users, tasks and control interfaces. As a result of the qualitative and quantitative assessments, we performed an analysis of possible improvements in the usability of a particular application of idTV. The results showed few differences between one multi-input control interface and one RC in tasks the user was familiar with, on the opposite, significant differences were found in performing tasks involving greater user interaction, such as the text input or navigation between menus. © Springer International Publishing AG 2017.Ítem Evaluation of various strategies to improve the training of a brain computer interface system(2013-01-01) Jiménez, L.D.; Trefftz, H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesBrain-computer interfaces (BCI) allow for communication between the human brain and computers. They have been used to create systems able to generate control over a software or mechatronic device, becoming an important tool for the rehabilitation of handicapped people, especially for patients with quadriplegia. Due to the importance of BCIs, any attempt to improve their response has a great value. The work described in this paper consists of the evaluation of various stimuli applied to improve the training of a BCI based system. The device is the Emotiv® EPOC which includes a Software Development Kit (SDK) to train the system. During the usual training of the SDK; images, videos, thoughts, movements and gestures were used as stimuli to improve the users' skills for accomplishing specific actions. After the evaluation of these stimuli, they were ranked according to their effectiveness. Finally, a powered wheelchair was controlled using the Emotiv® EPOC by applying the best-ranked stimulus and an assessment protocol was used in order to evaluate the performance of users driving the wheelchair with the BCI, with satisfactory results.Ítem Factores motivacionales en el desarrollo efectivo de operaciones BREC, realizadas por el Grupo USAR de la Armada Nacional(Universidad EAFIT, 2021) Aranzasu Alarcón, César Augusto; Uribe Botero, Paula; López Gallego, Francisco DaríoÍtem Poverty and Human Rights Violations(Universidad EAFIT, 2005-12-17) Kreide, Regine; Universidad de FrankfurtÍtem Using fear appeals in warning labels to promote responsible gambling among VLT players: the key role of depth of information processing.(Kluwer Academic Publishers / Plenum, 2010-12-01) Munoz Y; Chebat JC; Suissa JAVideo lottery terminals (VLT) are a highly lucrative gambling format, but at the same time they are among the most hazardous. Previous research has shown that threatening warnings may be an appropriate approach for promoting protective behavior. The present study explores the potential benefits of threatening warnings in the fight against compulsive gambling. A 4 x 2 factorial design experiment was used to test our model based on both Elaboration Likelihood Model and Protection Motivation Theory. 258 VLT adult players (58% males, 42% females) with various degrees of problem gambling were exposed to three threat levels (plus a control condition) from two different sources (i.e., either a medical source or a source related to the provider of VLT's). Our results show that both higher threat warnings and the medical source of warnings enhance Depth of Information Processing. It was also found that Depth of Information Processing affects positively attitude change and compliance intentions. The theoretical and managerial implications are discussed.
