E-loyalty in e-commerce: a study at GIRISSIMA.COM

Few studies have been conducted on causal antecedents for electronic loyalty regarding the online fashion industry. In Portugal there is no systematic empirical research in this area. This study aims to examine e-satisfaction and e-trust that potentially impact eloyalty. It also examines the impact of price, website design and selection of brands. A research study was performed at GIRISSIMA.COM and survey responses were 77. The findings show that e-satisfaction is the main driver of e-loyalty. E-trust, website design and price affect positively e-loyalty. Additionally, selection of brands was proved to impact e-loyalty through e-satisfaction and e-trust

Algorithms for infinite session types

Tese de Mestrado, Mestrado em Informática, 2022, Universidade de Lisboa, Faculdade de CiênciasIn concurrent interactions there are a large number of messages exchanged between two or more processes that often lead to coding errors. To simplify these interactions and reduce the coding errors, session types were created. Session types are an approach for structuring interaction protocols between multiple parties. When a channel is shared between two processes it is necessary to ensure that if one is sending a message, the other is prepared to receive it. In the same way, if a process offers some options, the complementary is prepared to select one of the options. There are finite types of messages, that perform an operation and stop, where you can perform send/receive or offer/select a message and terminate the interaction. However, not all of the interactions are possible just with finite types. This work presents an extension of session types into infinity, since it is necessary to study different classes of types with greater expressive power than finite types. Recursive and 1-counter types are the main focus of this thesis. We start by designing grammars so we can test equation systems based on those types. Defining rules in which the systems of these types can be written is the purpose of the grammars. These rules include the possibility of sending or receiving messages and selecting or offering a set of options. The grammars are implemented based on SePi, a concurrent programming language based on pi-calculus. All the systems that present a finite and infinite behavior should be tested. Constructing algorithms for type formation and type equivalence of these systems as well as testing those algorithms is the main goal of this project, so that we can be sure that infinite types, specifically, with different degrees of expressivity are correctly defined and able to be compared

The relevance of people management best practices on the preservation of employees' mental health: COVID-19 influence

The world is facing some of the most demanding moments in terms of mental health preservation, being this reality also reflected in the current People Management challenges. As COVID-19 started to spread, the world population was advised to adopt social distancing measures, as well as to perform their working obligations from home. This reality, alongside the already existent stressful organisational environments, lack of work-life balance and organisational resistance to the implementation of People Management best practices, can lead companies to struggle with economic prosperity and general development, strengthened by the reduction of employee’s performance. Therefore, the present study set out to analyse the impact of People Management Practices’ implementation on employees' mental health in the light of Organisational Engagement under a COVID-19 pandemic influence. The present research was built based on both primary and secondary data. The primary data was collected from a sample divided in two different perspectives: 1) Working population living in Portugal; 2) Selected Human Resources Consulting company. As main conclusions, it was possible to verify the foreseen existence of a relationship, in specific dimensions, between the implementation of People Management Best Practices and Organisational Engagement, as well as the impact of COVID-19 in the referred relation. The study’s originality can be guaranteed by the current existing literature gap regarding effective People Management practices under a COVID-19 perspective, which effectively allows the preservation of employees’ mental health and the mitigation of current realities such as burnout.O mundo enfrenta um dos momentos mais exigentes no que à preservação da saúde mental concerne, sendo esta uma realidade igualmente refletida à luz dos desafios contemporâneos da Gestão de Pessoas. Com o despoletar da pandemia COVID-19, a população mundial foi aconselhada a adotar medidas de distanciamento social, bem como a exercer a sua atividade profissional a distância. Como consequência do referido isolamento social e associando a presente realidade com os sempre existentes ambientes organizacionais stressantes, falta de equilíbrio entre trabalho e vida pessoal, bem como com a resistência organizacional à implementação de boas práticas de Gestão de Pessoas, poderá registar-se um abrandar no desenvolvimento e sustentabilidade organizacional, fruto da diminuição do desempenho dos colaboradores. Assim, o presente estudo propôs-se a analisar o impacto da implementação de boas práticas da Gestão de Pessoas, na saúde mental dos colaboradores, à luz da variável do engagement organizacional, numa perspetiva de influência COVID-19. A pesquisa teve como base dados primários e secundários, incidindo a recolha dos primeiros numa amostra dividida em duas vertentes: 1) População portuguesa economicamente ativa; 2) Consultora de Recursos Humanos selecionada. A relação de influência entre boas práticas de Gestão de Pessoas e engagement organizacional foi comprovada, em dimensões específicas, assim como o impacto da COVID-19 no referido efeito. A originalidade do estudo é comprovada pela lacuna atualmente existente na literatura, relativamente a práticas efetivas de Gestão de Pessoas, sob uma perspetiva COVID-19, na preservação da saúde mental dos colaboradores, com fim à mitigação de realidades como sendo o burnout

A atratividade física no processo de recrutamento & seleção: o papel da atração inicial unilateral

Cada vez mais têm surgido evidências de que a atratividade física é uma caraterística influenciadora nos mais variados contextos. Ao nível do processo de Recrutamento & Seleção (R&S), os resultados indicam que níveis mais elevados de atratividade física poderão promover preferências de contratação para estes candidatos. No âmbito do processo de R&S foram encontradas associações com entre a decisão de contratação dos candidatos o desejo de interação com os mesmos, sendo esta uma variável também associada com o fenómeno de atração inicial unilateral. Neste sentido, o presente estudo teve como objetivo analisar a influência da atratividade física no processo de R&S e perceber se esta relação seria mediada pela atração inicial unilateral. Foi também aplicada uma tarefa de sobrecarga cognitiva para analisar a ocorrência dos tipos de processamento de informação, heurístico e sistemático aquando a decisão de contratação. Foi pedido a uma amostra de 111 profissionais em Recursos Humanos (83 mulheres, Midade = 30 anos, DP = 7 anos), distribuídos pelas condições 2 (atratividade física: neutro vs. atraente) x 2 (sobrecarga cognitiva: com vs. sem), que analisassem o CV de um candidato a concorrer a uma vaga de emprego e tomassem a decisão de contratar ou não o mesmo. Os resultados não revelaram efeitos significativos da atratividade física na decisão de contratação, assim como a relação entre as duas variáveis não foi significativamente mediada pela atração inicial unilateral. Da mesma forma, a moderação através da sobrecarga cognitiva não se verificou. Contudo, verificou-se um efeito significativo da sobrecarga cognitiva na decisão de contratação. Os resultados são discutidos à luz do modelo heurístico-sistemático.Increasing evidence has emerged that physical attractiveness is an influential feature in a wide range of contexts. In the Recruitment and Selection process, the results indicate that higher levels of physical attractiveness may promote hiring preferences for these candidates. In the context of this process, associations were found between physical attractiveness and interaction with the candidate (Agthe, 2011). This variable was also associated with the unilateral initial attraction phenomenon (Rodrigues et al., 2017). In this sense, the present study aimed to analyze the influence of physical attractiveness on the R&S process and if this relationship would be mediated by the initial unilateral attraction phenomenon. A cognitive overload task was applied in order to analyze the ocurrence of different information processes throughout the hiring decision: heuristic and systematic. A sample of 111 professionals in Human Resources (83 women, Mage = 30 years, SD = 7 years), were assigned by conditions 2 (physical attractiveness: neutral vs. high) x 2 (cognitive overload: with vs. without). The task consisted in the analysis of the curriculum of a candidate to a job vacancy and to take the decision of to hire or not. There was no effects of the physical attractiveness on the hiring decision, as well as was no significant results of the mediation analysis. Likewise, a moderation through cognitive overload did not occur. However, there was a significant effect of cognitive overload on the hiring decision. The results are discussed in the light of the heuristic-systematic model

Soares dos Reis’ plaster models: technical production and the challenge of the conservation and restoration

Soares dos Reis’ natural gifts for the fine arts and the knowledge obtained during his academic career provided him with the tools for teaching and executing his work, considering clay models as a transitional material and original plaster models. The Museu Nacional Soares dos Reis (MNSR) houses among other works of art a great number of original plaster models. Nowadays, they are a source of technical information due to the execution marks left on the support. In a work project delineate between MNSR and José de Figueiredo Laboratory (LJF), six plaster sculptures were selected, with problems of alteration, to start the intervention process of conservation and restoration of the body of work authored by the sculptor

Mobilidade no Planeamento Sustentável das Cidades

A cidade, enquanto suporte territorial de deslocamentos diários, deve permitir que sejam realizados desafios e satisfeitas as necessidades da população. Atualmente, com a expansão dos aglomerados urbanos, estas capacidades têm vindo a ser ameaçadas nas suas diversas dimensões: ambientalmente, através do uso excessivo do transporte individual, economicamente, afetando o estimulo à economia, e socialmente, devido à degradação do espaço público. A mobilidade apresenta-se como um fator de extrema importância, com forte impacto no desenvolvimento sustentável das cidades. Uma vez que coopera para uma melhor qualidade de vida na cidade, devido ao contributo para uma maior equidade social, melhoria ambiental e estimulo à economia local. Deste modo, o estudo da mobilidade demonstra ser indissociável do estudo da cidade, ou seja, do seu planeamento e desempenho face à sustentabilidade. Ciente desta conexão, torna-se necessário analisar as variáveis de uso do solo associadas a uma mobilidade sustentável a fim de melhorar as práticas de planeamento urbano, focadas sempre nas necessidades diárias dos cidadãos. Neste sentido, a presente dissertação analisa em que medida o planeamento urbano influencia a mobilidade, mais concretamente os padrões de viagem, tendo em consideração características de uso do solo essenciais à eficiência de modelos de mobilidade implementados com sucesso. Este estudo aborda ainda o efeito das características socioeconómicas nos padrões de mobilidade atuais. Os principais resultados demonstram que para que exista uma mobilidade enquadrada no planeamento das cidades é necessário que as políticas de uso do solo, que influenciam os padrões de viagem, tenham em consideração as características socioeconómicas da população de modo a satisfazer as suas necessidades diárias. Deste modo, a mobilidade no planeamento da cidade segue dois eixos de desenvolvimento: a cidade compacta (densidade, diversidade de uso do solo e acessibilidade às infraestruturas de transporte) e mobilidade sustentável

Monitorização do crescimento de um biofilme fotossintético por análise de imagem

Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do grau de Mestre em Conservação e RestauroNo presente estudo, reproduziu-se em laboratório o crescimento de um biofilme fotossintético em três materiais pétreos usados em edifícios históricos: o calcário Ançã de Portugal, a piedra de San Cristóbal de Espanha e a pietra di Lecce de Itália. Estudou-se o crescimento do biofilme por análise de imagem utilizando os softwares Adobe® Photoshop®, HyperCube e ImageJ. Ao longo de 3 meses de incubação, a quantidade de biomassa fotossintética nos substratos pétreos foi determinada pela quantificação da clorofila a através do método espectrofotométrico. O aumento da concentração da biomassa fotossintética indicou a existência de crescimento endolítico na piedra de San Cristóbal. Este crescimento foi também observado através da análise de imagem, usando a Análise de Componentes Principais e a criação de imagens em falsa cor. O biofilme penetrou na piedra de San Cristóbal até uma profundidade de 3mm. Após 6 meses de incubação, observou-se o aumento da penetração do biofilme na piedra de San Cristóbal (penetração do biofilme 5 mm) e também a existência de crescimento endolítico na pietra di Lecce (penetração do biofilme 3 mm). Estimouse ainda no calcário Ançã a área superficial coberta pelo crescimento do biofilme através da análise de imagem, utilizando os resultados de um outro ensaio. A determinação de certas características físicas como a capilaridade e porosidade dos materiais pétreos foram preponderantes para compreender a colonização biológica

Environmental performance policy indicators for the public sector: The case of the defence sector

The development of environmental performance policy indicators for public services, and in particular for the defence sector, is an emerging issue. Despite a number of recent initiatives there has been little work done in this area, since the other sectors usually focused on are agriculture, transport, industry, tourism and energy. This type of tool can be an important component for environmental performance evaluation at policy level, when integrated in the general performance assessment system of public missions and activities. The main objective of this research was to develop environmental performance policy indicators for the public sector, specifically applied to the defence sector. Previous research included an assessment of the environmental profile, through the evaluation of how environmental management practices have been adopted in this sector and an assessment of environmental aspects and impacts. This paper builds upon that previous research, developing an indicator framework-SEPI-supported by the selection and construction of environmental performance indicators. Another aim is to discuss how the current environmental indicator framework can be integrated into overall performance management. The Portuguese defence sector is presented and the usefulness of this methodology demonstrated. Feasibility and relevancy criteria are applied to evaluate the set of indicators proposed, allowing indicators to be scored and indicators for the policy level to be obtained. (c) 2006 Elsevier Ltd.

However, the exercise intensity having the most benefts on lipids and infammatory markers in patients with T2DM remains unclear. We aimed to analyse the impact of a 1-year combined high-intensity interval training (HIIT) with resistance training (RT), and a moderate continuous training (MCT) with RT on infammatory and lipid profle in individuals with T2DM. Methods: Individuals with T2DM (n=80, aged 59 years) performed a 1-year randomized controlled trial and were randomized into three groups (control, n=27; HIIT with RT, n=25; MCT with RT, n=28). Exercise sessions were super‑ vised with a frequency of 3 days per week. Infammatory and lipid profles were measured at baseline and at 1-year follow-up. Changes in infammatory and lipid markers were assessed using generalized estimating equations. Results: After adjusting for sex, age and baseline moderate-to-vigorous physical activity (MVPA), we observed a time-by-group interaction for Interleukin-6 (IL-6) in both the MCT with RT (β=−0.70, p=0.034) and HIIT with RT (β=−0.62, p=0.049) groups, whereas, only the HIIT with RT group improved total cholesterol (β=−0.03, p=0.045) and LDL-C (β=−0.03, p=0.034), when compared to control. No efect was observed for C-reactive protein (CRP), cortisol, tumour necrosis factor-α (TNF-α), soluble form of the haptoglobin-hemoglobin receptor CD163 (sCD163), triglycerides and HDL-C in both groups (p>0.05). Conclusions: Favorable adaptations on IL-6 were observed in both the HIIT and MCT combined with RT groups fol‑ lowing a long-term 1-year exercise intervention in individuals with T2DM. However, only the HIIT with RT prevented further derangement of total cholesterol and LDL-C, when compared to the control group. Therefore, in order to encourage exercise participation and improve infammatory profle, either exercise protocols may be prescribed, however, HIIT with RT may have further benefts on the lipid profle.This work was supported by fellowships from the Portuguese Foundation for Science and Technology (JM grant: SFRH/BD/85742/2012; IRC grant: IRC: SFRH/BD/149394/2019).
