The impact of economic policy uncertainty on the real exchange rate: Evidence f...
Moldovan, P.; Lagoa, S.; Mendes, D.The world economy has been punctuated by uncertainty in recent years, as a result of the 2008 subprime crisis, the European sovereign debt crisis, Brexit, and the 2016 US presidential elections, to mention but a few of the reasons. This study explores how the UK real exchange rate reacts to economic policy uncertainty (EPU) shocks using monthly data for the period 1998 to 2020. We contribute to the literature b...
Causal inference of server- and client-side code smells in web apps evolution
Rio, A.; Brito e Abreu, F.; Mendes, D.Context Code smells (CS) are symptoms of poor design and implementation choices that may lead to increased defect incidence, decreased code comprehension, and longer times to release. Web applications and systems are seldom studied, probably due to the heterogeneity of platforms (server and client-side) and languages, and to study web code smells, we need to consider CS covering that diversity. Furthermore, the...
Situational-Context for Virtually Modeling the Elderly
Garcia-Alonso, J.; Berrocal, J.; Murillo, J.; Mendes, D.; Fonseca, C.; Lopes, M.The generalized aging of the population is incrementing the pressure over, frequently overextended, healthcare systems. This situations is even worse in underdeveloped, sparsely populated regions like Extremadura in Spain or Alentejo in Portugal. In this paper we propose an initial approach to use the Situational-Context, a technique to seamlessly adapt Internet of Things systems to the needs and preferences of...
Psychometric Properties of the Elderly Nursing Core Set
Fonseca, C.; Lopes, M.; Mendes, D.; Parreira, P.; Mónico, L.; Marques, M.C.Aim: To assess the psychometric properties of the Elderly Nursing Core Set. Methods: Cross-sectional descriptive study; convenience sample composed of 427 individuals aged 65 years old or older. Results: Factor analysis of principal components allowed extracting 4 concepts, i.e., Self-Care, Learning and Mental Functions, Communication, and Relationship with Friends and Caregivers, which explained 82.25% of the ...
Healthcare Computer Reasoning Addressing Chronically Ill Societies Using IoT: D...
Mendes, D.; Lopes, M.; Romão, A.; Rodrigues, I.The authors present a proposal to develop intelligent assisted living environments for home based healthcare. These environments unite the chronical patient clinical history sematic representation with the ability of monitoring the living conditions and events recurring to a fully managed Semantic Web of Things (SWoT). Several levels of acquired knowledge and the case based reasoning that is possible by knowled...
An Approach to Help Identifying Optimized Service Areas of Integrated Continuou...
Oliveira, H.; Lopes, M.; Fonseca, C.; Goes, M.; Mendes, D.; Caeiro, J.Objectives: To find how many elderly persons with 65 years and older are within a service area of each Integrated Continuous Care Team (Equipa de Cuidados Continuados Integrados - ECCI), with each area computed around the geographic location of each ECCI headquarters and encompassing all accessible streets that can be reached within a certain travel time spent on driving a vehicle. Methods: A Geographic Informa...
Exploring the Role of ICTs in Healthy Aging
Mendes, D.; Fonseca, C.; Lopes, M.; Garcia-Alonso, J.; Murillo, J.Technological innovation continues to be present in all areas of our lives, offering seemingly endless possibilities. As technology is increasingly implemented in healthcare applications, it is necessary to understand whether users respond to a predefined organizational strategy of model of care or whether they will become wholly dependent on the healthcare technology. This understanding is especially crucial w...
Handbook of Research on Health Systems and Organizations for an Aging Society
Fonseca, C.; Lopes, M.; Mendes, D.; Mendes, F.; Garcia-Alonso, J.Population aging is a growing challenge worldwide. As such, new models of provision, organization, and allocation of resources, particularly in healthcare, are needed. As the self-care and long-term care needs of this age group become more prevalent, the importance of improved health services and effective health management strategies are apparent. The Handbook of Research on Health Systems and Organizations fo...
Occlusion-aware pedestrian detection and tracking
Correia, S.; Mendes, D.; Jorge, P.; Brandão, T.; Arriaga, P.; Nunes, L.This paper proposes an occlusion-aware mechanism, used on a framework for detecting and tracking pedestrians in videos acquired from surveillance cameras, which includes the extraction of trajectory points, estimation of walking velocities, detection of groups, and projection of the final trajectories into a 2D plan. The occlusion-aware mechanism is introduced in order to manage irregularities in the pedestrian...
Multi-camera person re-identification based on trajectory data
Mendes, D.; Correia, S.; Jorge, P.; Brandão, T.; Arriaga, P.; Nunes, L.This study presents a trajectory-based person re-identification algorithm, embedded in a tool to detect and track customers present in a large retail store, in a multi-camera environment. The customer trajectory data are obtained from video surveillance images captured by multiple cameras, and customers are detected and tracked along the frames that compose the videos. Due to the characteristics of a multi-came...
