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…
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 …
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…
Factors Affecting Digital Tool Use in Client Interaction According to Mental Health Professionals : Interview Study
2023
Background: Digital tools and interventions are being increasingly developed in response to the growing mental health crisis, and mental health professionals (MHPs) considerably influence their adoption in client practice. However, how MHPs use digital tools in client interaction is yet to be sufficiently understood, which poses challenges to their design, development, and implementation. Objective: This study aimed to create a contextual understanding of how MHPs use different digital tools in clinical client practice and what characterizes the use across tools. Methods: A total of 19 Finnish MHPs participated in semistructured interviews, and the data were transcribed, coded, and inductiv…
CNO and pep solar neutrino measurements and perspectives in Borexino
2015
International audience; The detection of neutrinos emitted in the CNO reactions in the Sun is one of the ambitious goals of Borexino Phase-II. A measurement of CNO neutrinos would be a milestone in astrophysics, and would allow to solve serious issues in current solar models. A precise measurement of the rate of neutrinos from the pep reaction would allow to investigate neutrino oscillations in the MSW transition region. The pep and CNO solar neutrino physics, the measurement in Borexino Phase-I and the perspectives for the new phase are reviewed in this proceeding.
Measurement of Solar pp-neutrino flux with Borexino: results and implications
2015
International audience; Measurement of the Solar pp-neutrino flux completed the measurement of Solar neutrino fluxes from the pp-chain of reactions in Borexino experiment. The result is in agreement with the prediction of the Standard Solar Model and the MSW/LMA oscillation scenario. A comparison of the total neutrino flux from the Sun with Solar luminosity in photons provides a test of the stability of the Sun on the 10(5) years time scale, and sets a strong limit on the power production by the unknown energy sources in the Sun.
On the Finite Element Modeling of the Lumbar Spine: A Schematic Review
2023
Finite element modelling of the lumbar spine is a challenging problem. Lower back pain is among the most common pathologies in the global populations, owing to which the patient may need to undergo surgery. The latter may differ in nature and complexity because of spinal disease and patient contraindications (i.e., aging). Today, the understanding of spinal column biomechanics may lead to better comprehension of the disease progression as well as to the development of innovative therapeutic strategies. Better insight into the spine’s biomechanics would certainly guarantee an evolution of current device-based treatments. In this setting, the computational approach appears to be a remarkable …
The Role of Fc Receptors on the Effectiveness of Therapeutic Monoclonal Antibodies.
2021
Since the approval of the first monoclonal antibody (mAb) in 1986, a huge effort has been made to guarantee safety and efficacy of therapeutic mAbs. As of July 2021, 118 mAbs are approved for the European market for a broad range of clinical indications. In order to ensure clinical efficacy and safety aspects, (pre-)clinical experimental approaches evaluate the respective modes of action (MoA). In addition to antigen-specificity including binding affinity and -avidity, MoA comprise Fc-mediated effector functions such as antibody dependent cellular cytotoxicity (ADCC) and the closely related antibody dependent cellular phagocytosis (ADCP). For this reason, a variety of cell-based assays have…
Functional Extrapolations to Tame Unbound Anions in Density-Functional Theory Calculations
2019
Standard flavors of density-functional theory (DFT) calculations are known to fail in describing anions, due to large self-interaction errors. The problem may be circumvented using localized basis sets of reduced size, leaving no variational flexibility for the extra electron to delocalize. Alternatively, a recent approach exploiting DFT evaluations of total energies on electronic densities optimized at the Hartree-Fock (HF) level has been reported, showing that the self-interaction-free HF densities are able to lead to an improved description of the additional electron, returning affinities in close agreement with the experiments. Nonetheless, such an approach can fail when the HF densitie…
