- Reação do sistema da corporate governance aos abusos dos acionistas controladoresPublication . Bastos, João Manuel de Almeida Lima Tavares; Pereira, Jorge Manuel de BritoOs problemas associados ao controlo acionista já não são uma novidade, no entanto, continuam a estar muito atuais tendo em conta a evolução das estruturas empresariais, consequência do impacto da globalização. Neste trabalho vamos analisar os mecanismos legais de combate aos problemas relacionados com os acionistas controladores tentando demonstrar quais as principais insuficiências do mesmo e oferecendo algumas sugestões de eventuais soluções a esses problemas. Faremos um pequeno enquadramento definindo quem são os acionistas, o que é o controlo e quais são os riscos que derivam da presença dos mesmos.
- How footwear companies can use online CX to WOW customersPublication . Silva, Susana C.; Dias, Joana Carmo; Braga, BeatrizPurpose: E-commerce has become an essential and highly competitive channel for e-retailers, who have felt the need to invest in the experience delivered to customers. Therefore, it becomes necessary to unveil the online customer experience so that brands can improve their offerings. In this study, the authors proposed a model that explores customer experience on websites, namely, what concerns the use of the latest technological developments such as artificial intelligence, augmented reality and virtual reality. Design/methodology/approach: The study offers a model to explore and compare the online consumer experience in e-commerce websites, considering eight dimensions that cover recent technological advances. A multiple case study that evaluated companies in the footwear industry was used to assess the model's applicability. The case study methodology considered two distinct segments, the high-price and low-price segments. Findings: The data collected by the websites' examination enabled us to confirm part of the suggested propositions. However, propositions concerning new technologies were not proved. Opportunities for improvement were identified, especially for high-price segment companies, since the results showed that these companies provide a less pleasant consumer experience than those of the opposing segment. Originality/value: This study extends the scope of the online consumer experience by introducing more contemporary dimensions. Additionally, the model allows an evaluation and comparison of the knowledge delivered by several online retailers, using the Portuguese footwear industry as a reference.
- A utilização de OKRs por empresasPublication . Soares, Patrícia Alexandra Damião; Marques, Luís Manuel DionísioAs organizações deparam-se constantemente com as suas mais diversas complexidades, num contexto cada vez mais globalizado e com uma concorrência acentuada. É fundamental para as empresas, definirem a sua estratégia, para aumentar a sua capacidade competitiva, através do apoio de metodologias de gestão. Tem havido uma crescente procura e aplicação dos OKRs (Objectives and Key Results), por empresas. Com este Estudo de Caso, pretende-se analisar o uso da metodologia OKRs, inserido no seu plano estratégico, alcançando alinhamento e solidez diária. O método utilizado neste trabalho é exclusivamente qualitativo. Foram realizadas duas entrevistas a colaboradores com responsabilidades de gestão na Retail Mind e na Caixa de Crédito Agrícola Mútuo Beira Centro. De forma a testar a aplicabilidade dos OKRs, em ambas as empresas. Também foi realizado um Workshop na Retail Mind, onde foram apresentadas as vantagens dos OKRs. E onde tive a oportunidade de apresentar a minha Proposta de OKRs para a organização. As conclusões obtidas neste estudo, indicam-nos que as organizações irão adotar cada vez mais esta nova metodologia. É um aliado positivo para alcançar os objetivos desejados, através da sua simplicidade e pelo seu lado motivador.
- Glutathione for food and health applications with emphasis on extraction, identification, and quantification methods: a reviewPublication . Al-Temimi, Anfal Alwan; Al-Mossawi, Aum El Bashar; Al-Hilifi, Sawsan A.; Korma, Sameh A.; Esatbeyoglu, Tuba; Rocha, João Miguel; Agarwal, VipulGlutathione is a naturally occurring compound that plays a crucial role in the cellular response to oxidative stress through its ability to quench free radicals, thus mitigating the risk of potential damage, including cell death. While glutathione is endogenously present in different plants and animal cells, their concentration varies considerably. The alteration in glutathione homeostasis can be used as a potential marker for human diseases. In the case of the depletion of endogenous glutathione, exogenous sources can be used to replenish the pool. To this end, both natural and synthetic glutathione can be used. However, the health benefit of glutathione from natural sources derived from fruits and vegetables is still debated. There is increasingly growing evidence of the potential health benefits of glutathione in different diseases; however, the determination and in situ quantification of endogenously produced glutathione remains a major challenge. For this reason, it has been difficult to understand the bioprocessing of exogenously delivered glutathione in vivo. The development of an in situ technique will also aid in the routine monitoring of glutathione as a biomarker for different oxidative stress-mediated diseases. Furthermore, an understanding of the in vivo bioprocessing of exogenously delivered glutathione will also aid the food industry both towards improving the longevity and profile of food products and the development of glutathione delivery products for long-term societal health benefits. In this review, we surveyed the natural plant-derived sources of glutathione, the identification and quantification of extracted glutathione from these sources, and the role of glutathione in the food industry and its effect on human health.
