    No full text
    This thesis develops a strategic framework for expanding project sales of Volkswagen Group Services Consulting Iberia (VWGSC Iberia) across European markets. A country ranking model, combining internal and external data and a PESTEL-based trend analysis, identified five priority countries. Complemented by an in-depth market assessment, Portugal, Spain, and the UK were selected for focused growth. For these markets, tailored market development strategies and a project-based financial forecast confirm the expansion’s viability. The thesis concludes with strategic recommendations to strengthen internal visibility and enhance sales structures, providing a scalable framework for future international growth within the VW Group

    This work project develops a practical, Excel- and PowerPoint-based guideline for implementing the EU taxonomy at Hamburger Energienetze GmbH. Based on delegated acts, internal company data, and expert interviews, the tool enables systematic eligibility checks, alignment assessments, and KPI calculations. Two representative activities were analysed to validate the methodology and highlight key challenges, including regulatory uncertainty, limited data availability, and interde partmental coordination. Results confirm the feasibility of low-resource implementation and em phasise the value of standardised processes and internal documentation. The proposed guideline is transferable to other CSRD-covered organisations and supports compliance with taxonomy report ing requirements, thereby increasing transparency and audit readiness

    The role of SPF claims on packaging and their influence on men’s purchase intent and willingness to pay for skincare products in the Portuguese market

    No full text
    This research explored how SPF claims on packaging affect skincare purchases among Portuguese men (18-29). Using literature reviews and 20 in-depth interviews, the study found SPF claims positively influence specific groups like outdoor enthusiasts. However, skepticism, confusion about SPF values, price sensitivity, and masculine social norms significantly limit overall impact. Participants showed limited understanding of SPF benefits beyond basic sun protection, preferring simple, non-greasy products. Peer/partner influence outweighed traditional advertising. Recommendations include clear, relatable messaging on minimalist packaging, products offering tangible value at accessible prices, and leveraging trusted channels to normalize SPF use in men's self-care routines

    O presente relatório surge na sequência da realização de um estágio não-curricular no leitorado do Camões, Instituto da Cooperação e da Língua, I.P., em Paris, na Universidade Paris VIII - Vincennes-Saint-Denis, no âmbito da componente não letiva do Mestrado em Português como Língua Segunda e Estrangeira da Faculdade de Ciências Sociais e Humanas, da Universidade NOVA de Lisboa. Este debruça-se sobre o percurso da estagiária na instituição de acolhimento e em outros polos de intervenção. Este estágio compreendeu uma componente de acompanhamento pedagógico de turmas do ensino superior com estudantes que têm o português como língua estrangeira ou como língua de herança, e dos seus principais desafios, na continuidade do ensino do português. Procura-se ainda, com este relatório, ilustrar as temáticas mais prementes que enfrenta o português neste contexto específico e como estão a ser abordadas e solucionadas pela equipa do leitorado. Como o português está representado no ensino superior e de que forma sobrevive, encontrando novas formas de adaptação num meio que não o considera como uma língua estratégica. Procede-se, igualmente, à análise de como é efetuada a promoção e difusão do português como língua de cultura no ensino superior francês e junto do público francófono e da comunidade portuguesa na diáspora; das estratégias utilizadas nas várias situações encontradas, inerentes à natureza de um leitorado que, por si, funciona como um pequeno núcleo do país de origem num segundo país, e dos obstáculos e soluções encontrados no desenrolar do estágio. O relatório divide-se em duas partes, uma primeira com seis capítulos de enquadramento teórico, de análise das políticas utilizadas e dos seus custos/benefícios e do papel do Camões, I.P., e da importância da programação cultural. Na segunda parte, é descrito o percurso de estágio, numa estrutura de cinco capítulos, onde se salienta a importância de existir uma continuidade no ensino de português através do percurso escolar francês, de modo a garantir a sobrevivência do português no ensino superior, com a captação de alunos neste percurso e se sublinha a importância de uma política diplomática que ajude na transformação da perceção atual do português como língua de emigração para língua de cultura.This report is the result of a non-curricular internship at the Camões, Instituto da Cooperação e da Língua, I.P., lectureship in Paris, at the University Paris VIII - Vincennes-Saint-Denis, as part of the non-teaching component of the Master's programme in Language Studies. Vincennes-Saint-Denis, as part of the non-teaching component of the of the master’s degree in Portuguese as a Second and Foreign Language at the Faculty of Social Sciences and Humanities of NOVA University Lisbon. It focuses on the intern's career in the host institution and in other centres of intervention. This internship comprises a component of pedagogical accompaniment of higher education classes that have Portuguese as a foreign language and as a heritage language, and their main challenges in the continuity of Portuguese learning. The aim of this report is also to illustrate the most pressing issues that Portuguese faces in this specific context and how they are being addressed and resolved by the lectorate's team. How Portuguese is represented in higher education and how it survives, finding new ways to adapt in an environment that does not consider it a strategic language. It also analyses how Portuguese is promoted and disseminated as a language of culture in French higher education and among a French-speaking public and the Portuguese diaspora; the strategies used in the various situations encountered, inherent to the nature of a lectorate, which in itself functions as a small nucleus of the country of origin in a second country, and the obstacles and solutions encountered during the course of the internship. The report is divided into two parts, the first with six chapters on the theoretical framework, analysing the policies used and their costs/benefits, the role of Camões, I.P. and the importance of cultural programming. In the second part, the internship programme is described in a five-chapter structure, which emphasises the importance of continuity in the teaching of Portuguese throughout the French school career, in order to guarantee the survival of Portuguese in higher education, by attracting students along this path, and stresses the importance of a diplomatic policy to help transform the current perception of Portuguese as a language of emigration into a language of culture

    No full text
    Com os crescentes laços económicos entre a China e Angola, especialmente no âmbito da iniciativa “Uma Faixa, Uma Rota”, os intercâmbios e a cooperação entre os dois países têm vindo a aprofundar-se nos domínios político, económico, cultural e outros. Sendo a língua oficial de Angola, o português tornou-se uma língua fundamental para as empresas chinesas fazerem negócios e localizarem as suas operações no país. Embora a língua desempenhe um papel importante na comunicação intercultural, as empresas chinesas em Angola enfrentam sérias barreiras linguísticas e problemas de adaptação cultural, que não só limitam a sua eficiência de gestão e a qualidade da tomada de decisões, como também afetam a comunicação eficaz com os empregados, clientes e parceiros locais. Através de um inquérito por questionário e da análise de dados dos trabalhadores de empresas chinesas em Angola, este estudo explora sistematicamente o papel específico do ensino da língua portuguesa para negócios na melhoria das competências de comunicação intercultural, no reforço da adaptação cultural e na promoção da criação de equipas multiculturais. Os resultados do estudo mostram que o ensino do português para negócios não só melhora efetivamente as competências linguísticas dos trabalhadores, como também aumenta a sua sensibilidade e adaptabilidade à comunicação intercultural, o que, por sua vez, melhora a comunicação interna e o desenvolvimento de negócios internacionais da empresa. Além disso, a formação linguística tem um efeito particularmente significativo na promoção da gestão intercultural, especialmente na criação de equipas multiculturais e na formação da imagem internacional da empresa. Com base nestas conclusões, o presente texto propõe recomendações para promover o desenvolvimento sustentável do ensino da língua portuguesa, incluindo a formulação de planos de ensino a longo prazo, a atualização do conteúdo dos cursos de modo a satisfazer as necessidades em constante mudança das empresas, a criação de redes de cooperação educativa internas e externas, e o estabelecimento de um mecanismo de avaliação científica e de feedback para a formação linguística. Estas recomendações têm como objetivo ajudar as empresas chinesas em Angola a enfrentar melhor com os desafios interculturais, a conseguir uma comunicação e colaboração mais eficientes e a aumentar a sua competitividade e influência no mercado global. Através deste estudo, espera-se fornecer apoio teórico e orientação prática para a gestão intercultural das empresas chinesas em Angola e noutros países lusófonos, bem como fornecer conhecimentos e referências úteis para o desenvolvimento do ensino do português para negócios.With the growing economic ties between China and Angola, especially withintheframework of the “Belt and Road Initiative,” exchanges and cooperation betweenthetwocountries have been deepening in political, economic, cultural, and other fields. As the official language of Angola, Portuguese has become a fundamental language for Chinese companiesto conduct business and establish their operations in the country. Although language playsacrucial role in intercultural communication, Chinese companies in Angola face significant language barriers and cultural adaptation challenges, which not only limit their management efficiency and decision-making quality but also affect effective communication with employees, clients, and local partners. Through a questionnaire survey and data analysis of employees in Chinese companies in Angola, this study systematically explores the specific role of teaching Portugueseforbusiness purposes in improving intercultural communication skills, enhancing cultural adaptation, and fostering the development of multicultural teams. The study’s findingsindicate that business Portuguese education not only effectively improves employees’language skills but also increases their sensitivity and adaptability to intercultural communication, which in turn enhances internal communication and the international business development of companies. Additionally, language training has a particularlysignificant effect on promoting intercultural management, especially in the creationofmulticultural teams and the development of the company’s international image. Based on these findings, this paper proposes recommendations to promotethesustainable development of Portuguese language education, including the formulationoflong-term teaching plans, the updating of course content to meet the ever-changing needsofcompanies, the establishment of internal and external educational cooperation networks, andthe creation of a scientific evaluation and feedback mechanism for language training. Theserecommendations aim to help Chinese companies in Angola better cope with intercultural vi challenges, achieve more efficient communication and collaboration, and enhancetheircompetitiveness and influence in the global market. Through this study, it is expected to provide theoretical support and practical guidance for the intercultural management of Chinese companies in Angola and other Portuguese-speaking countries, as well as offervaluable insights and references for the development of business Portuguese education

    Será que os homens leem livros escritos por mulheres? Um estudo exploratório do caso português (2022-2023)

    No full text
    Esta dissertação pretende dar resposta à pergunta que lhe serve de premissa: “Será que os homens leem livros escritos por mulheres?” Tem como ponto de partida o estudo sobre hábitos de leitura por género encomendado no Reino Unido por Mary Ann Sieghart, publicado em 2021 em The Authority Gap, revelador de que os leitores homens não leem livros escritos por mulheres. Analisam-se estudos semelhantes feitos anteriormente em contexto académico e não-académico, que fundamentam uma reflexão sobre género e literatura que não é de agora. De Virginia Woolf, em 1929, com Um Quarto Só Seu, a Joanna Russ, em 1983, com How To Suppress Women’s Writing, destacam-se vozes que denunciaram e questionaram a marginalização da literatura produzida por mulheres ao longo dos tempos. Também em Portugal, a história da escrita de mulheres é marcada pelo silenciamento e pela exclusão, como sublinham autoras como Ana Paula Ferreira ou Isabel Allegro de Magalhães. Olhando para os nomes d’O Cânone, as escritoras portuguesas continuam a ser uma minoria. A premissa central desta dissertação é sustentada por um estudo exploratório, com o objetivo de encontrar uma resposta quantitativa para a interrogação. O estudo foi realizado com uma amostra de 400 leitores – 200 homens e 200 mulheres – de um grupo de Facebook português que partilhou online as suas escolhas literárias entre maio de 2022 e fevereiro de 2023. O resultado é idêntico ao do estudo de Sieghart: 81% dos leitores homens escolheram livros escritos por homens. Será o pseudónimo – um mecanismo historicamente usado pelas mulheres para penetrarem num mundo literário masculino – ainda hoje uma poderosa ferramenta para o reconhecimento literário? Analisam-se casos de sucesso de pseudónimos neutros e femininos, no estrangeiro e em Portugal. Explora-se também a importância, a génese e as dificuldades de iniciativas maioritariamente independentes que têm promovido a literatura de mulheres em Portugal: livrarias feministas (Greta), editoras especializadas (Aurora), clubes de leitura (Leitoras de Pandora), coletivos de autoras (Clube das Mulheres Escritoras), bibliotecas feministas (Biblioteca especializada Ana de Castro Osório) e projetos de investigação académica (Escritoras de língua portuguesa no tempo da Ditadura Militar e do Estado Novo em Portugal, África, Ásia e países de emigração). Mais do que um estudo sobre hábitos literários, este trabalho pretende refletir sobre as barreiras que continuam a limitar a literatura de mulheres e o seu reconhecimento, abrindo caminho para futuras pesquisas, mais aprofundadas, que possam expandir a discussão e alterar os comportamentos de leitura e os preconceitos literários dominantes.This dissertation seeks to address the guiding question: “Do men read books written by women?” It uses as its starting point the study on reading habits by gender commissioned in the United Kingdom by Mary Ann Sieghart and published in The Authority Gap in 2021, which revealed that male readers do not read books by women. Additionally, similar studies, both academic and non-academic, are analyzed to support a reflection on gender and literature that extends beyond the current century. From Virginia Woolf, in 1929, with A Room of One’s Own, to Joanna Russ, in 1983, with How To Suppress Women’s Writing, voices have consistently denounced and questioned the marginalization of literature produced by women throughout history. In Portugal, too, the history of women 's literature is marked by silencing and exclusion, as underscored by authors such as Ana Paula Ferreira and Isabel Allegro de Magalhães. Looking at the names within the literary canon, Portuguese women writers continue to be a minority. The central premise of this dissertation is further supported by an exploratory study, aiming to find a quantitative answer to the question. The study was conducted with a sample of 400 readers from a Portuguese Facebook group – 200 men and 200 women – who shared their literary choices online between May 2022 and February 2023. The results align with Siegharts findings: 81% of male readers chose a book written by a man. Is the pseudonym – a mechanism historically employed by women to enter into a male-dominated literary world – still a powerful tool for literary recognition today? Successful cases of neutral and feminine pseudonyms are examined, both in Portugal and abroad. The dissertation also explores the importance, origins, and challenges of primarily independent initiatives that promote women’s literature in Portugal: feminist bookshops (Greta), specialised publishers (Aurora), reading clubs (Leitoras de Pandora), author collectives (Clube das Mulheres Escritoras), feminist libraries (Biblioteca especializada Ana de Castro Osório), and academic research projects (Escritoras de língua portuguesa no tempo da Ditadura Militar e do Estado Novo em Portugal, África, Ásia e países de emigração). More than a study on literary habits, this work aims to reflect on the barriers that continue to limit the recognition of women’s literature, paving the way for more in-depth future research that could expand the discussion and change reading behaviors and prevailing literary biases

    RESUMO: Introdução: As doenças cardiovasculares (CVD) são a principal causa de morte em todo o mundo, e também em Portugal, assumindo-se como um dos principais fatores responsáveis pela perda da qualidade de vida. Diversos estudos têm salientado o papel da alimentação como fulcral para a prevenção das CVD. Objetivo: Este estudo centrou-se na avaliação do impacto de uma dieta do tipo mediterrânea nos fatores de risco cardiovasculares (CRFs) em indivíduos com elevado risco para a doença. Metodologia: Trata-se de um ensaio clínico randomizado, decorrido na região do Algarve entre julho e dezembro de 2023. Foram recrutados 102 participantes (≥50 anos) sem histórico de enfarte agudo do miocárdio, mas com critérios de risco de CVD elevado segundo o algoritmo SCORE2/SCORE2 OP. Parâmetros antropométricos e de composição corporal [peso corporal, índice de massa corporal (BMI), perímetro da cintura (WC), perímetro do braço, prega cutânea bicipital e tricipital, massa gorda, massa muscular e gordura visceral], como também bioquímicos (colesterol total, lipoproteína de baixa densidade (LDL c), lipoproteína de elevada densidade (HDL-c), triglicerídeos (TG), hemoglobina glicada (HbA1c) e proteína c-reativa (CRP) foram avaliados no início da intervenção e no final, após 12 semanas de intervenção. Foi também avaliada a adesão à dieta mediterrânica (MD) segundo aplicação do PREDIMED. Os participantes foram, aleatoriamente, randomizados em três grupos: grupo sem intervenção (grupo 1a), grupo de exercício físico (grupo 1b) e grupo exercício físico e dieta (grupo 2). Resultados: Apenas 88 participantes deram por concluído o estudo. A amostra era maioritariamente constituída por mulheres (73,9%) e apresentavam uma idade média de 70,1 ± 7,9 anos. Para a variável peso corporal, BMI, prega cutânea tricipital, massa gorda e massa muscular, ambos os grupos apresentavam resultados estatisticamente significativos. O grupo 2 foi o único grupo com melhorias significativas no WC, prega cutânea bicipital, gordura visceral, área muscular do braço e triglicerídeos. No grupo 1b, verificou-se uma diminuição significativa no colesterol total e HDL-c. Entre grupos, apenas foram observadas diferenças significativas na variável LDL-C, HDL-c, HbA1c e prega cutânea tricipital. Relativamente à adesão à MD, ambos os grupos, no início, apresentavam moderada adesão, contudo, após a intervenção, apenas o grupo 2 apresentou alta adesão (p=0,024). Conclusão: O nosso estudo veio demonstrar que uma alimentação do tipo mediterrânica, sem restrição calórica, incrementada com alimentos de base vegetal, diariamente, promove a melhoria dos parâmetros cardiometabólicos, como o perímetro da cintura e a gordura visceral.ABSTRACT: Introduction: Cardiovascular diseases (CVD) are the leading cause of death worldwide, including Portugal, serving as one of the primary factors contributing to the deterioration of quality of life. Numerous studies have underscored the pivotal role of diet in preventing CVD. Objective: This study aimed to assess the impact of a Mediterranean-type on cardiovascular risk factors (CRFs) in individuals at high risk for the disease. Methodology: This was a randomized clinical trial conducted in the Algarve region between July and December 2023. A total of 102 participants (≥50 years old) without a history of acute myocardial infarction but with high CVD risk criteria according to the SCORE2/SCORE2 OP algorithm were recruited. Anthropometric and body composition parameters [body weight, body mass index (BMI), waist circumference (WC), arm circumference, bicipital and tricipital skinfold thickness, fat mass, muscle mass, and visceral fat], as well as biochemical parameters (total cholesterol, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), triglycerides (TG), hemoglobina glicada (HbA1c), and C-reactive protein (CRP), were evaluated at baseline and after 12 weeks of intervention. Adherence to the Mediterranean Diet (MD) was also assessed using the PREDIMED questionnaire. Participants were randomly assigned to three groups: no intervention group (group 1a), physical exercise group (group 1b), and physical exercise and diet group (group 2). Results: Only 88 participants completed the study. The sample was predominantly composed of women (73.9%) with a mean age of 70.1 ± 7.9 years. For the variables of body weight, BMI, tricipital skinfold thickness, fat mass, and muscle mass, both groups showed statistically significant results. Group 2 was the only group with significant improvements in WC, bicipital skinfold thickness, visceral fat, arm muscle area, and TG. In group 1b, a significant decrease in total cholesterol and HDL-c was observed. Between groups, significant differences were observed only in the LDL-C, HDL, HbA1c, and tricipital skinfold thickness variables. Regarding adherence to the MD, both groups initially showed moderate adherence; however, after the intervention, only group 2 showed high adherence (p=0.024). Conclusion: Our study has demonstrated that a Mediterranean-type diet, without caloric restriction, supplemented with plant-based foods daily, promotes improvement in cardiometabolic parameters such as WC and visceral fat.Project 072590 – A3COR – Algarve Active Ageing – Cardiac and Osteoarthritis Rehabilitation and by the Universidade Católica Portugues

    Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Digital TransformationGenerative artificial intelligence (GenAI) has been attracting increased attention since the appearance of ChatGPT in 2022. It is a technology that is presented as having the potential to trigger significant changes in how people work. Prior studies have focused heavily on GenAI usage in an educational and academic context application, although, there are still few studies on outcomes for professionals, both from an instrumental scope and a humanistic perspective. To explore these research goals, this study dives into the outcomes that GenAI usage might have for professionals, namely on wellbeing, job engagement, management control and productivity. Moreover, it is also explored the moderation roles of trust, perceived social presence, and decision support on the afore-mentioned outcomes. To evaluate the previous goals, we collected answers from 306 professionals who leverage GenAI to some extent. The findings revealed that leveraging GenAI for enabled job learning has a major contribution towards professionals´ wellbeing and job engagement, management control, and productivity. Moreover, we also found that perceived social presence is a mediator between GenAI enabled job learning and management control. Additionally, we also observed that in a scenario in which professionals have a high usage of GenAI for decision support, enabled job learning becomes more important in explaining productivity’s variance

    Dissertation presented as the partial requirement for obtaining a Master's degree in Data Science and Advanced Analytics, specialization in Business AnalyticsThis study explores the perceptions of different generations regarding the use of AI tools and related techniques in the work field. Applying the unified theory of acceptance and use of technology 2 (UTAUT2) as the theoretical framework, complemented by the empowerment theory, this research aims to understand the factors influencing the adoption and use of AI tools among Portuguese employees, and the impact that these factors are causing. Data was collected through a survey which included 321 respondents, whose responses were analyzed using partial least squares structural equation modeling (PLS-SEM). The findings reveal that social influence, price value, hedonic motivation, and habit significantly impact the intention to use AI tools and the use behavior. On the other hand, performance expectancy, effort expectancy, and facilitating conditions were not found to significantly influence the intention to use or the actual use behavior. Additionally, the study highlights the importance of access to information, resources, and support in fostering AI-human co-creation, as well has the moderator effect of workload in the final outcomes. The results provide valuable insights for organizations aiming to enhance AI adoption and integration in the workplace, based on the impacts on productivity and innovation that it may have at work environments. Thus, the study emphasizes the need for supportive or collaborative work environments and addresses potential barriers to technology acceptance

    No full text
    Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Digital TransformationWearable technologies are increasingly integrated into consumers’ daily lives, offering realtime data and seamless connectivity. In tourism and, particularly, in the cruise sector, wearable sensors provided by cruise companies are emerging as key tools to enhance passengers’ experience onboard. This study investigates the impact of these devices on two critical outcomes: individual performance and social wellbeing. Grounded on the beliefaction-outcome (BAO) framework, this research examines how key beliefs, as perceived convenience, privacy concerns, social influence, and perceived benefits influence passengers’ intention to use and actual usage of wearable sensors. The study further explores the moderating roles of social influence and loyalty in shaping these relationships. Using partial least squares structural equation modeling (PLS-SEM) with a sample of 301 cruise passengers, collected through an online survey, results reveal that both the intention to use and actual usage of wearable sensors significantly improve individual performance and social wellbeing of cruise passengers. These findings extend the BAO framework to a consumer-level tourism context, contributing to the wearable technology and smart tourism literature, and offering practical insights for cruise operators seeking to enhance passenger experience through strategic technology adoption
