Exploring the Limitations of Responsive Design Through a Case Study Approach

Authors
Almeida, FL; Monteiro, JA;

Publication
International Journal of Web Portals

Abstract
Having an online presence is essential for any company regardless of its size and type of business. Users are currently striving to interact with companies through the web, regardless of their access device. In this sense, responsive web design emerged as a very useful technique that allows the dynamic adaptation of the design regardless of the size and resolution of the access device. Despite the unequivocal advantages associated with this technique, there are also limitations which turn this approach not feasible or advisable for all projects. This study, through the realization of five case studies, seeks to identify the main limitations of responsive design and responsive design frameworks. Additionally, this study suggests further development models that may be more effective in the dynamic adaptation of the design and contents according to the features of the access device, such as the adoption of adaptive design, use of native apps, and hybrid models.

Exploring the Impact of COVID-19 on the Sustainability of Health Critical Care Systems in South America

Authors
Almeida, F;

Publication
International Journal of Health Policy and Management

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has created strong pressure on national health critical care systems. After its initial impact in Asia, the highest case growth is now in the Americas. The South American countries face a strong challenge due to the vulnerabilities of their health systems and the fragile socio-economic conditions of their population. This perspective looks at the impact of COVID-19 in South America and argues that the health critical care systems of these countries are particularly vulnerable due to the underestimation of the number of cases currently confirmed and the strong need for treatment of these patients in intensive care units (ICUs). In particular, Bolivia will need to increase the number of ICU beds 60-fold while Brazil will need to grow 12-fold to meet the growth rates of COVID-19 by the end of July 2020. In this sense, it is argued that national and transnational measures should be taken urgently to face this challenge. Furthermore, it is necessary to perform tests to detect COVID-19 cases earlier to alleviate the need for internment in ICUs.

Research Anthology on Decision Support Systems and Decision Management in Healthcare, Business, and Engineering

Abstract
The use of agile methodologies like SCRUM is seen by companies in the software engineering field as a strategic necessity for their competitiveness, which makes them more reactive and dynamic in an increasingly demanding and competitive international market. One of the critical factors in the implementation of a SCRUM environment is the set-up of teams that are simultaneously homogeneous and composed of the best collaborators for each SCRUM role. In this sense, this study describes the modeling process and presents the implementation of a decision support system that can contribute to improving the process of assigning an agile team simultaneously considering the technical and social skills of employees. The results of the study allowed testing the application considering different competencies associated to each Agile position, the impact that the attribution process suffers from oscillations in the process of evaluation and self-evaluation, and the impact in terms of the performance of the inclusion of new collaborators and criteria comparison.

Encyclopedia of Information Science and Technology, Fifth Edition - Advances in Information Quality and Management

Abstract
This chapter looks to the accessibility good practices that should be adopted in the development of e-Government platforms. To this end, accessibility issues and implemented good practices in e-government services portals of the Top-4 countries in the overall e-Government Benchmark 2017 are comparatively analyzed. Despite the recognized work of those countries in the digitization of public services and the existence of relevant good practices, there are still relevant issues in accomplishment accessibility standards, particularly in the structuring of websites, the use of alternative text to images and videos, the adoption of alternatives to flash technology and the use of high contrast colors.

EXPLORING THE RELATIONSHIP BETWEEN BIG DATA AND FIRM PERFORMANCE

Authors

Publication
MANAGEMENT RESEARCH AND PRACTICE

Abstract
Big data offers great potential to improve organizational performance and generate competitive advantages. In this sense, knowing this phenomenon is relevant and this study aims to explore the role of big data on firm performance through a process of synthesis of several studies that have been published in recent years in different organizational contexts. This study adopts a mixed-methods approach. Initially, a systematic literature review is performed to characterize the studies that adopt structural equation modeling to determine the relationship between big data and firm performance. Additionally, a meta-analysis method is used to quantify the association between these two phenomena. The findings reveal a moderate positive relationship between the adoption of big data in the firm performance. This ratio is estimated at 0.38 with a confidence interval between 0.32 and 0.44 for a significance level of 0.05. The results of this study also allow us to conclude that the performance of organizations is also determined by other factors such as human capital, the data-driven organizational culture, or the learning capacity of the organization. This study offers mainly implications for companies that intend to invest in big data to know the potential value of this technology in organizational performance.
