Despite numerous studies on digital tools in tourism and hospitality, few quantitative investigations use an integrated set of these tools to enhance business success. This study examines the impact of digital tools on hospitality business performance, using data from 234 SMEs in Portugal's accommodation sector. Findings show that integrating tourist accommodation into business groups positively influences digi...

A data drift approach to update deployed energy prediction machine learning models

While there is an increasing interest in Machine Learning (ML) based solutions, scarce research has been devoted to the deployment and monitoring of ML models. In this work, we address this research gap by proposing a new data drift ML update strategy that only considers changes in the input features. Using the realistic Growing Window (GW) and Rolling Window (RW) ML deployment simulation schemes, we propose tw...

Cardiorespiratory fitness in postmenopausal women: relationship with indirect m...

The impairment of cardiorespiratory fitness associated with arterial stiffness has been related to excessive physiological changes, being considered important predictors of risk of cardiovascular diseases (Albin et al., 2020). Evidence on the interaction between cardiorespiratory fitness, arterial stiffness and cardiovascular stress in postmenopausal women remains limited. This relationship analysis proves to b...

The importance of artificial intelligence in postprandial blood glucose predict...

Many works are using artificial intelligence to forecast postprandial blood glucose. However, the following questions arise: is it necessary to develop artificial intelligence techniques to predict blood glucose? How important is artificial intelligence for this purpose? This work gives some insights seeking the answer to these questions in the context of using postprandial blood glucose predictions to optimize...

The influence of range of motion on the functional and structural capacity of t...

Range of motion in exercises is one of the foundations for greater activation of a muscle group. The objective of this investigation was to compare the structural and functional capacity of the triceps brachii between three groups with different angles (90°, 110°, and 130°) in a unilateral elbow extension exercise. The sample consisted of 25 subjects with a mean age of 24.12 ± 3.83 years, mean height of 1.78 ± ...

The influence of resilience on the digital resilience of higher education stude...

The rapid digital transformation and the COVID19 pandemic have altered the teaching and learning processes of higher education students. However, despite the use of more digital instruments and methodologies, their use alone does not guarantee greater success in digital education, and students who have greater personal resources such as resilience tend to obtain better results. To balance the effects of digital...

Azereiral da serra da Estrela, uma relíquia da Laurissilva – Guia de Campo

Este guia foi elaborado no âmbito do Projeto Life-Relict, um projeto de conservação que teve lugar nos anos 2017-23, tendo como grande objetivo a preservação de um dos mais importantes habitats da serra da Estrela: o azereiral. Esta publicação pretende dar a conhecer o azereiral ao público em geral. Para isso, apresentam-se algumas das suas particularidades históricas, florísticas e ecológicas, assim como a sua...
