Existence of non trivial embeddings of interval exchange transformations into p...
Peres, Pedro; Rodrigues, AnaWe prove that almost every interval exchange transformation, with an associated translation surface of genus ≥2 , can be non-trivially and isometrically embedded in a family of piecewise isometries. In particular, this proves the existence of invariant curves for piecewise isometries, reminiscent of Kolmogorov–Arnold–Moser (KAM) curves for area-preserving maps, which are not unions of circle arcs or line segments.
Renormalization of translated cone exchange transformations
Cockram, Noah; Ashwin, Peter; Rodrigues, AnaIn this paper, we investigate a class of non-invertible piecewise isometries on the upper half-plane known as Translated Cone Exchanges. These maps include a simple interval exchange on a boundary we call the baseline. We provide a geometric construction for the first return map to a neighbourhood of the vertex of the middle cone for a large class of parameters, then we show a recurrence in the first return map...
Volunteer management in sports tourism events: Motivation and satisfaction as d...
Antunes, Hélio; Rodrigues, Ana; Gouveia, Élvio; Lopes, Helder; Sabino, BebianaEffective volunteer management in sports tourism events depends on understanding motivations, segmenting profiles, and fostering satisfaction to ensure continuity and event success. The purpose of this study was to examine volunteer motivation, investigate differences in motivation based on gender and age, and identify key predictors of the intention to continue volunteering. The sample consisted of 390 partici...
Inclusion of Optic Nerve Assessed by Visual Evoked Potentials in Dissemination ...
Delgado, Sofia; Timóteo, Ângelo; Moniz Dionísio, Joana; Rodrigues, Ana; Arraiolos, Ana; Lopes das Neves, Pedro; Rêgo, André; Vale, José; Salgado, VascoIntroduction: Optic nerve (ON) inclusion as the fifth location in dissemination in space (DIS) for the diagnosis of multiple sclerosis (MS) was proposed in 2016 by the Magnetic Resonance Imaging in Multiple Sclerosis Group. However, there was insufficient evidence to include this recommendation in the 2017 revision of McDonald criteria. Our objective was to investigate the effect of including ON involvement ass...
Association between Body Composition, Physical Activity Profile, and Occurrence...
Ashraf, Sadaf; Viveiros, Roberto; França, Cíntia; Ornelas, Rui Trindade; Rodrigues, AnaKnee and foot deformities refer to structural abnormalities in the knee and foot bones, joints, ligaments, or muscles. Various factors, including genetics, injury, disease, or excessive use, can cause these deformities. These musculoskeletal conditions can significantly impact individuals’ quality of life. This study examined foot and knee deformities in 231 young healthy adults (165 men, 66 women) aged 22.6 ± ...

Cultural Indicators as a Tool for Assessing Sustainable Development in the Alto...
Mota, Miguel Ângelo Sousa Dias Ferreira da; Silva, Andreia; Vieira, Isabel; Fernandes, Didiana; Rodrigues, AnaCulture has been particularly emphasised over the years in discussions about sustainable development, being considered as one of its fundamental pillars alongside the environmental, economic, and social dimensions. The measurement of the impact of culture on sustainable development is still very incipient, so the purpose of this study is to study how culture can influence the sustainable development of the Alto...
Instagram as a digital marketing tool of a hotel brand
Silva, Cândida; Silva, Susana; Rodrigues, AnaSocial media marketing is increasingly seen as one of the main ways of communicating with consumers, platforms where visual content is the main form of communication, such as Instagram. The human brain is programmed to not only pay attention to individual resources, but also to the stories that these resources tell. Stories allow humans to relate, inspire, motivate, and often be persuaded, because they mix info...
Residents’ Perceptions of Sustainable Tourism Development in an Emerging Destin...
Mota, Miguel Ângelo Sousa Dias Ferreira da; Vieira, Isabel; Rodrigues, Ana; Alén, ElisaDespite extensive research into the residents’ perceptions of sustainable tourism development (STD) over the past few decades, there has been little exploration of emerging destinations in low-density regions. This study uses a bidirectional analysis to segment the residents of a historic town in the north of Portugal (Lamego), which is part of the Douro World Heritage delimitation. This study applies a factor-...
