Grounded Theory—An illustrative application in the Portuguese footwear industry
Monteiro, M.; Rosa, A.; Martins, A.; Jayantilal, S.Grounded theory is an inductive research methodology aiming at the construction of new concepts or new theories able to explain emerging phenomena. The objective of this paper is to provide insights on the usage of grounded theory in management research. We showcase how grounded theory can bring light to development modes of Portuguese small and medium-sized enterprises (SME) in the specific reality of the foot...
Uncovering dimensions of the impact of blockchain technology in supply chain ma...
Tokkozhina, U.; Martins, A.; Ferreira, J.Supply chains around the globe are faced with difficulties and disruptions due to the worldwide pandemic situation and digital solutions are needed. There is significant research interest in the implementation of blockchain technology (BCT) for supply chain management (SCM). A challenge that remains is analyzing the interactions of BCT in different areas of SCM. This study aims to identify the influential dimen...
Implementation of disruptive technologies for the last mile delivery efficiency...
Elvas, L. B.; Tokkozhina, U.; Martins, A.; Ferreira, J.he last mile delivery (LMD) is one of the most tangled procedures in logistics. The reason is that it involves various uncertainties, including weather and road conditions, traffic hours and route selection, car accidents, delivery vehicle anomalies, at the same time needing to avoid parcel damages and delivery errors, while communicating with the recipient of the parcel. Above-mentioned factors cause the diffi...
Multi-tier supply chain behavior with blockchain technology: Evidence from a fr...
Tokkozhina, U.; Martins, A.; Ferreira, J.Relationships in multi-tier supply chains (MTSCs) are complex and require constant information sharing. For MTSCs involved in perishable product distribution, blockchain technology (BCT) is one of the most promising technologies that can ensure products’ traceability and safety. This study examines a Portuguese MTSC for frozen fish products piloting BCT adoption for its supply chain (SC) practices. The goal is ...
Decentralizing online food delivery services: A blockchain and IoT model for sm...
Tokkozhina, U.; Mataloto, B.; Martins, A.; Ferreira, J.With the worldwide pandemic outbreak, the style of restaurant food consumption underwent a major shift towards online delivery services. This poses an urgent need in trust between main stakeholders of the process: requiring restaurants to correspond to the quality declared, providing high quality and safe to consume meals, and obliging delivery entities to deliver food carefully, scrupulously following the deli...

Silva, E.; Viegas, D.; Martins, A.; Almeida, J.; Almeida, C.; Neves, B.; Madureira, P.; Wheeler, A. J.; Salavasidis, G.; Phillips, A.; Schaap, A.By creating a dependable, transparent, and cost-effective system for forecasting and ongoing environmental impact monitoring of exploration and exploitation activities in the deep sea, TRIDENT seeks to contribute to the sustainable exploitation of seabed mineral resources. In order to operate autonomously in remote locations under harsh conditions and send real-time data to authorities in charge of granting lic...
O papel da inteligência artificial nos transportes e na logística
Martins, A.; Ferreira, J.; Vale, J.São muitas as situações que ultimamente nos fizeram olhar para as cadeia de abastecimento com outros olhos, desde a ruptura de abastecimento de algums materiais durante o período do COVID-19, à paragem da passagem dos navios no canal da mancha por um grande navio ter encalhado. Este novo olhar não é de estranhar, afinal todos os produtos que temos à nossa volta passaram por uma cadeia de abastecimento, muitos d...
Metal-ion zeolites obtained by chemical and mechanochemical methods as Fenton-l...
Costa, J. T.; Ivasiv, V.; Bertão, A. R.; Nunes, N.; Mestre, A. S.; Carvalho, A. P.; Baltazar, F.; Moreira, J. N.; Neves, Isabel C.; Martins, A.One of the critical steps for the development and health applications of inorganic nanoparticles is to exhibit high efficiency without inducing toxicity. In this work, metal-ion zeolites were developed to be used as Fenton-like catalysts for health applications. ZSM-5 and BEA zeolites were modified through chemical and mechanochemical methods to obtain nanomaterials with tuned particle size and texture. Charact...
Organoleptic chemical markers of Serpa PDO cheese specificity
Araújo-Rodrigues, H.; Martins, A.; Tavaria, Freni; Santos, Maria Teresa; Carvalho, Maria João; Dias, João; Alvarenga, Nuno; Pintado, M.Serpa is a protected designation of origin cheese produced with a vegetable coagulant (Cynara cardunculus L.) and raw ovine milk. Despite the unique sensory profile of raw milk cheeses, numerous parameters influence their sensory properties and safety. To protect the Serpa cheese quality and contribute to unifying their distinctive features, some rheologic and physicochemical parameters of cheeses from four PDO...
