- Profiling the employment and wage features on the portuguese accommodation and food services activities before and after the COVID-19 pandemicPublication . Nunes, Alcina; .According to the Tourism Agency of the United Nations (UN Tourism), in most regions of the world, women comprise most of the tourism workforce and tend to concentrate on the lowest-paid and lowest-status jobs in tourism. Indeed, literature recognises that tourism is one of the sectors with a feminised labour force. In Portugal, tourism is a crucial sector of the Portuguese economy and contributes significantly to wealth and job creation. This paper analyses the sector’s employment and wage characteristics before and after the COVID-19 pandemic, focusing on wage gender disparities. Using data from the National Statistical Office (INE), the study highlights the sector’s susceptibility to economic shifts and the exacerbation of existing wage inequalities due to the pandemic. The analysis reveals that while the sector experienced severe job losses and wage declines during the pandemic, there has been a gradual recovery, albeit with persistent gender wage gaps and a high reliance on part-time employment. The findings underscore the need for targeted policy measures to support the sector’s resilience and promote gender equality in the workforce, ensuring a more equitable recovery in the post-pandemic period.
- A practical approach to teaching differential robot control using a goal-to-goal interfacePublication . Amorim, Johann; Moraes, Camile; Neto, Accacio; Amorim, Josef; Santos, Patricia; Lima, José; Haddad, Diego; Pinto, Milena F.This paper presents an interface to assist students in performing robot controllers. This application is designed to stabilize the movement of a goal-to-goal robot. The primary objective is to enhance the learning experience by offering an easy application that showcases the robot's behavior based on its kinematic model. The paper outlines the various stages involved in developing and testing this simple interface, including a study of the kinematics of differential robots. It discusses the discrete-time equations for goal-to-goal behavior, the data required to obtain the controller, the application of the controller in a discrete microcontroller, and the development of code to simulate the robot's behavior. The results show the developed interface and the possible outcomes through the use of this application in control classes.
- Using websites to disclose information on human capital: an exploratory study in the portuguese banking sectorPublication . Carmo, Cecília M. R.; Leite, Joaquim; Lima, BeatrizThis study examines the use of websites by Portuguese banks to disclose information about their human capital. For this purpose, a manual content analysis was carried out, based on an analysis grid that allows to identify the elements that are disclosed. The results show that banks already use websites to disclose information on human capital, but at a low level. There are also topics related to human capital information that no bank discloses on its website.
- Sahub - stackoverflow and comments integrationsPublication . Oliveira, André; Matos, Paulo; Oliveira, Pedro FilipeThis paper proposes a novel approach for connecting StackOverflow discussions and open source codebases through a graph database model in Neo4j. By encouraging developers to adopt a structured annotation framework using widely known tags such as @ author, @description, @ link, @tags, and optional fields such as @operatingSystem and @fileExtension, the paper will discuss how to link code snippets to specific technical questions. These annotations are then analyzed, creating an interconnected knowledge graph that can associate StackOver-flow questions with real-world code examples and additional documentation pulled directly from code snippets.
- Tourism ecosystems new challengesPublication . Guarda, T.; Augusto, Maria Fernanda; Villao, Datzania; Lopes, Isabel Maria; .The global challenges in terms of climate change, sustainability and traveler behavior are having a profound impact on tourism ecosystems, which are evolving. This paper identifies these challenges and recommends novel governance solutions to enable sustainable tourism ecosystem ports. Through an integration of ecological balance and economic efficiency, they underscore the importance of interdisciplinary approaches that account for environmental, cultural and socioeconomic aspects. Examples such as the sustainable management of the Galápagos Islands highlight the feasibility of integrating conservation and tourism development within fragile ecosystems. This research highlights the importance of aligning global tourism trends with local characteristics through an investigation of emerging trends and key sustainability principles. The results indicate that multi-stakeholder collaboration, adaptive strategies, and technology-driven innovations are necessary for successful tourism ecosystem management, balancing conservation with economic growth.
- Optimization of machine learning models applied to robot localization in the robotatfactory 4.0 competitionPublication . Klein, Luan C.; Mendes, João; Braun, João A.; Martins, Felipe N.; Fabro, João Alberto; Costa, Paulo; Pereira, Ana I.; Lima, JoséSeveral approaches have been developed over time aiming to improve the localization aspects, especially in mobile robotics. Besides the more traditional techniques, mainly based on analytical models, artificial intelligence has emerged as an interesting alternative. The current study proposes to explore the machine learning model structure optimization for pose estimation, using the RobotAtFactory 4.0 competition as the main context. Using a Bayesian Optimization-based framework, the parameters of a Multi-Layer Perceptron (MLP) model, trained to estimate the components of the 2D pose (x, y, and !) of the robot were optimized in four different scenarios of the same context. The results obtained showed a quality improvement of up to 60% on the estimation when compared with the modes without any optimization. Another aspect observed was the different optimizations found for each model, even in the same scenario. An additional interesting result was the possibility of the reuse of optimization between scenarios, presenting an interesting approach to reduce time and computational resources.
- The importance of using biometric sensors in elderly peoplePublication . Guarda, T.; Vitor, J.A.M.; Lopes, Isabel Maria; .The world population is aging. Aging brings several health issues that society is challenged to overcome. There is a pressing need to have effective solutions to monitor the health conditions of the elderly population. Keeping track of elderly health conditions can prevent some diseases and allow early diagnosis and treatment, enhancing the elderly’s quality of life. Biometric sensors are a great solution because they do not just measure health conditions but are able to provide a picture of how an individual is. Studies have already shown the potential of using biometric data for researching new health prevention approaches, improving selected aspects of health care, and personalizing hyper medication. The ultimate goal would be to achieve the so-called personal medicine [1]. These considerations invite an examination of the state of the art of the technologies used on this topic.
- Non-governmental organizations and innovation in the fish productive chain: combining the lenses of the sustainability balanced scorecard and information systemsPublication . Leite, Joaquim; Carmo, Cecília M. R.; Almeida, DanilsaThe objective of this research is to understand how to use the theoretical lens of the Sustainability Balanced Scorecard (SBSC) and information systems to explain innovation in the fish productive chain. The research method was the case study of a single Non-Governmental Organization (NGO) in São Tomé and Príncipe. Evidence was collected from content analysis and a long interview with the president of the NGO’s board of directors. The results showed that each new international funding for the NGO depends on the satisfaction of the partners involved (volunteer donors and beneficiaries/users) in previous projects, which in turn depends on the investment in facilities and equipment. Sustainability and innovation, as NGO’s strategic objectives, can be explained in the four traditional perspectives of the BSC because it is important to interpret the financial and non-financial effects.
- Exploring wearable device acceptance: an empirical studyPublication . Sá, Matheus Beltrame de; Niada, Áurea; Pereira, João Paulo; Lopes, Isabel MariaIn this study, the objective was to understand the receptivity to wearable devices in Portugal and Brazil, analyzing factors such as demographic characteristics, technological experiences and personal opinions. To achieve this, we adapted the Unified Technology Acceptance and Use Model 2 (UTAUT2) model and collected responses from university students and frequent internet users using a Likert scale questionnaire. Data analysis revealed a majority of Portuguese participants and a stronger trend of acceptance among the youngest, most educated and those with the greatest affinity with technology, especially men. The proportion of users and non-users of wearables was balanced, with greater acceptance among individuals aged 35 to 59, women and those with a positive attitude towards technology. Surprisingly, social influence did not prove to be as decisive in the acceptance of wearables as initially assumed. The results indicate a growing preference for the adoption of these devices, but also point to challenges related to the perceived value and, consequently, the cost of the products, which suggests a promising terrain for future research and technological advances.
- CVTool: automating content variants of cvsPublication . Gonçalves, Julio Beites; Pereira, Maria João; Henriques, Pedro RangelAs academic professionals, we frequently need to create different versions of our CVs for project applications, career evaluations, or competitions. These versions may be chronologically structured or skill-oriented, covering specific periods and written in various languages. Even when using a LaTeX document as a base, numerous modifications are required each time an updated CV version is requested for a specific purpose. The primary objective of the project reported in this paper is to design and implement a web-based system (CVTool) that simplifies the management of LaTeX CV content while ensuring flexibility. The CVTool is built on a domain-specific language that enables the creation of various filters, allowing for the automatic content adjustment while preserving the original format. Information is extracted from the LaTeX document, and users can specify the sections, dates, skills they want to highlight, and the language in which the CV should be generated. Since the approach relies on an internal data representation derived from the original LaTeX document, it offers users the flexibility to manage content efficiently and extract the necessary information with ease.
