Single Event Transients and Pulse Quenching Effects in Bandgap Reference Topologies for Space Applications
2016
An architectural performance comparison of bandgap voltage reference variants, designed in a $0.18~\mu \text {m}$ CMOS process, is performed with respect to single event transients. These are commonly induced in microelectronics in the space radiation environment. Heavy ion tests (Silicon, Krypton, Xenon) are used to explore the analog single-event transients and have revealed pulse quenching mechanisms in analogue circuits. The different topologies are compared, in terms of cross-section, pulse duration and pulse amplitude. The measured results, and the explanations behind the findings, reveal important guidelines for designing analog integrated circuits, which are intended for space appli…
Effects of Minimalist Footwear and Foot Strike Patterns on Plantar Pressure during a Prolonged Running
2022
The use of minimalist shoes (MS) in running involves changes in running mechanics compared to conventional shoes (CS), but there is still little research analysing the effects of this footwear on plantar pressure, which could help to understand some risk injury factors. Moreover, there are no studies examining the effects of a prolonged running and foot strike patterns on baropodometric variables in MS. Therefore, the aim of this study was to analyse the changes produced using MS on plantar pressure during a prolonged running, as well as its interaction with the time and foot strike pattern. Twenty-one experienced minimalist runners (age 38 ± 10 years, MS running experience 2 ± 1 years) ran…
Research Perspectives: Reconsidering the Role of Research Method Guidelines for Interpretive, Mixed Methods, and Design Science Research
2021
Information systems (IS) scholars have proposed guidelines for interpretive, mixed methods, and design science research in IS. Because many of these guidelines have also been suggested for evaluating what good or rigorous research is, they may be used as a checklist in the review process. In this paper, we raise the question: To what extent do research guidelines for interpretive, mixed methods, and design science research offer evidence that they can be used to evaluate the quality of research. We argue that scholars can use these guidelines to evaluate what good research is if there is compelling evidence that they lead to certain good research outcomes. We use three well-known sets of gu…
Why not complain? A paradoxical problem for mobile service and application providers
2014
Complaints from dissatisfied users of information systems (IS) help service and product providers decrease user churn and switching, prevent negative word-of-mouth, and improve their services and products. However, many dissatisfied individuals do not complain at all; rather, they remain silent, switch, or quit usage. The dilemma is particularly relevant in the context of mobile services and applications, in which only a fraction of users has been found to complain after negative experiences, even extreme ones. Although researchers have studied the reasons for complaining, only a few have investigated the reasons why individuals do not complain. To our best knowledge, there are no studies e…
Digitālo rīku efektivitāte personīgo finanšu pārvaldīšanā
2018
Bakalaura darbā “Digitālo rīku efektivitāte personīgo finanšu pārvaldīšanā” pētīta digitālo rīku izmantošanas efektivitāte personīgo finanšu pārvaldīšanā un studentu finanšpratības līmenis. Pētījuma mērķis ir noteikt, vai digitālie rīki var kalpot par efektīvu instrumentu, ar kuru palīdzību iespējams īstenot personīgo finanšu pārvaldīšanas procesu. Lai sasniegtu izvirzīto mērķi, bakalaura darbā izmantotas kvantitatīvas un kvalitatīvas pētniecības metodes – anketēšana, daļēji strukturētā intervija, dienasgrāmatas metode un kvalitatīvā kontentanalīze. Iegūtie dati analizēti un interpretēti, balstoties uz pragmatisma metateoriju un teorētisko modeli ELIS. Rezultāti parāda, ka digitālie rīki sn…
An Empirical Examination of the Economics of Mobile Application Security
2021
The growth of mobile devices coupled with the advances in mobile technologies has resulted in the development and widespread use of a variety of mobile applications (apps). Mobile apps have been developed for social networking, banking, receiving daily news, maintaining fitness, and for job-related tasks. The security of the apps is an important concern. However, in some cases, the app developers may be less interested to invest in the security of the apps, if users are unwilling to pay for the added security. In this paper, we empirically examine whether consumers are less willing to pay for security features than for usability features. In addition, we examine whether a third-party certif…
Estereotipos asociados al cuerpo humano: análisis de aplicaciones móviles usadas en la educación físico-deportiva
2022
Institutions and educators are massively and uncritically integrating digital curricular materials in their teaching praxis. This article aims to uncover whether health and fitness APP images convey or legitimize stereotypes linked to bodies, focusing on gender, race, somatotype and physical activity practice. We also analyse whether these apps are adequate for the recommended age or whether they are designed by physical education professionals. For that purpose, we designed a descriptive, comparative study based on content analysis on a sample of 373 images from 128 apps selected through a PRISMA review and a pilot test. Our results report that bodies reproduce a series of stereotypes: of …
Designing New learning Environments for Music - Implementing the MobiKid experience
2009
In 2006-2008 a mobile software application MobiKid for children aged 3-6 was developed to allow children to sing, record and listen to the songs independently at home. They could even forward the recorded songs to be downloaded from a server by their teacher and relatives. With not yet completed user interface (UI) features the program offered children a motivating context for singing and musical creativity. The child-centered MobiKid UI was developed collaboratively by different experts of music education and software engineering. MobiKid pilot study was expected to reflect the preliminary requirements for child-centered software and usability features for further development among informa…
Validation and Extension of the Usability Heuristics for Mobile Map Applications
2016
Heuristic usability evaluation is light but efficient method for finding usability problems. In this paper, we report the process of validation and further development of the previously introduced usability heuristics for mobile map applications. The validation began by testing the heuristics by 58 evaluators who used them for usability evaluation of four different map applications. The evaluators also filled a questionnaire about the understandability of the heuristics. The amount, severity and quality of the problems found with the heuristics were reviewed and the heuristics’ understandability analyzed. As a result, it was shown that the heuristics were efficient for finding usability pro…
Customers' Perceived Risk and Trust in Using Mobile Money Services—an Empirical Study of Ghana
2019
Although mobile money (MM) has been explored in the existing literature, the roles of trust and risk in MM use have received little attention from researchers. Furthermore, many of the existing studies have treated these constructs as unidimensional. The extant literature also shows that perceived risk has received little attention from researchers who have conducted studies on MM. Thus, the objective of this study is to examine the roles of trust and perceived risk in customers' intent to adopt MM services in Ghana. Both trust and perceived risk were broken down into various dimensions. The study involved 671 respondents who were selected via an intercept approach and an online survey. Str…
