Enhancing the SCIROCCO tool using quantitative and qualitative methods
2018
Background: The SCIROCCO tool, developed as part of the SCIROCCO project, incorporates the Maturity Model for the adoption of Integrated Care developed by the European Innovation Partnership on Active and Healthy Ageing (B3 Action Group on Integrated Care). The online self-assessment tool can be used to facilitate scaling-up of integrated care across different health and care sectors, at different levels in health or care systems, and in a range of communities. Currently, more than 30 European regions are involved in testing the SCIROCCO tool. Since the project launch in April 2016, the tool underwent two iterations. Each of the iterations of the tool was followed by a round of refinement t…
Investigating teachers motivation to use ICT tools in higher education
2015
There are a lot of information and communication technology (ICT) tools for education, but the motivation to use those varies from teacher to teacher. In this paper we present results of an international survey on teachers' use of ICT tools in education. The purpose of the survey was to find out what motivates teachers to use ICT tools in the context of teaching. The survey also intended to reveal which tools are used as well as the needs and requirements that are not covered by the existing tools. Most of the 45 respondents suggested that the integration of tools depends on how well they fit into the learning and teaching process and how easy it is to integrate them. The first category of …
Using Slack for computer-mediated communication to support higher education students’ peer interactions during Master’s thesis seminar
2018
Our study contributes to the research on computer-mediated communication in higher education by experimenting a modern communication tool called Slack. In particular, we consider using Slack to support students’ peer interactions during Master’s thesis work. For this purpose, we designed a case study that was executed in a Master’s thesis seminar course. During the course, all out-of-class communication was carried out by using Slack, instead of e-mails or learning management systems. After the course, we used a questionnaire to investigate how the students perceived Slack for asking for assistance, their intention to use Slack, and Slack’s ease of use. Furthermore, the questionnaire asked …
The perceived time value importance for enrolment in online masters courses: an extension of the Technology Acceptance Model
2020
Purpose. The main objective of this research is to obtain a better understanding of the impact of perceived time value on the intention of pursuing an online Master’s degree for its applicants. For this reason, perceived time value is added to the Technology Acceptance Model. Design/methodology/approach. Data are collected from a purposive sample of 147 individuals, who were interested to continue their higher education. Both, online and personal surveys are used to collect data. Achieved data are analysed by structural equation modelling. Findings. The results show that the perceived time value is significantly related to the ease of use and perceived utility, which in turn, show a signifi…
User-Centered Design for Biomedical Literature Search User Interfaces
2019
Biomedical literature search tools are crucial resources for the work of physicians, biologists, and bioinformatics. Many of the genetic-medical diagnoses depend on the findings in these literature resources. Despite the importance and value of the information stored in these resources, the user interface (UI) implemented by such tools present several usability problems converting the query and interpretation of the information into complex and time-consuming tasks. In this sense, an user-centered design (UCD) approach can improve the usability of these UIs facilitating the interaction, analysis, and comparison of biomedical information, and, consequently, improving the productivity of prac…
Assessment of the Usability and Accuracy of Two-Diode Models for Photovoltaic Modules
2017
Many diode-based equivalent circuits for simulating the electrical behaviour of photovoltaic (PV) cells and panels are reported in the scientific literature. Two-diode equivalent circuits, which require more complex procedures to calculate the seven model parameters, are less numerous. The model parameters are generally calculated using the data extracted from the datasheets issued by the PV panel manufactures and adopting simplifying hypotheses and numerical solving techniques. A criterion for rating both the usability and accuracy of two-diode models is proposed in this paper with the aim of supporting researchers and designers, working in the area of PV systems, to select and use a model…
A Criterion for Rating the Usability and Accuracy of the One-Diode Models for Photovoltaic Modules
2016
In selecting a mathematical model for simulating physical behaviours, it is important to reach an acceptable compromise between analytical complexity and achievable precision. With the aim of helping researchers and designers working in the area of photovoltaic systems to make a choice among the numerous diode-based models, a criterion for rating both the usability and accuracy of one-diode models is proposed in this paper. A three-level rating scale, which considers the ease of finding the data used by the analytical procedure, the simplicity of the mathematical tools needed to perform calculations and the accuracy achieved in calculating the current and power, is used. The proposed criter…
Assessment of the Usability and Accuracy of the Simplified One-Diode Models for Photovoltaic Modules
2016
Models for photovoltaic (PV) cells and panels, based on the diode equivalent circuit, have been widely used because they are effective tools for system design. Many authors have presented simplified one-diode models whose three or four parameters are calculated using the data extracted from the datasheets issued by PV panel manufactures and adopting some simplifying hypotheses and numerical solving techniques. Sometimes it may be difficult to make a choice among so many models. To help researchers and designers working in the area of photovoltaic systems in selecting the model that is fit for purpose, a criterion for rating both the usability and accuracy of simplified one-diode models is p…
Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a…
2021
Background Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America. Methods Two studies will be described: Study 1 is focused on the cultural adaptation o…

The aim of this study is to contribute to a better understanding of challenges and factors which influence learning efficiency with electronic-portfolios. Based on the Technology Acceptance Model (TAM; Davis, Bagozzi, & Warshaw, 1989) we analyzed external variables (e.g., computer-anxiety) that influence technology acceptance and the actual system use in form of self-regulated learning. Additionally we included computer related attitudes and correlated them with external variables as well as measures of self-regulated learning. To foster learning efficacy with electronic portfolios the program Microsoft OneNote was used. A group of N = 32 preservice teachers worked on an electronic-port…
