- Evaluating the role of digital technologies in enhancing warehouse efficiencyPublication . Perkumienė, Dalia; Samuolaitis, Mindaugas; Hasanov, Jamil; Dinis, Maria Alzira Pimenta; Safaa, Larbi; Leal Filho, Walter; Perkumienė, Dalia; Dinis, Maria Alzira PimentaThis article evaluates the role of digital technologies in enhancing warehouse efficiency, using Amazon as a case study. Over the past few years, the corporation has been using its new technology capabilities to create digital solutions that increase operational efficiency. Digital technology offers significant advantages in areas including accuracy, productivity, information sharing, and inventory control. Therefore, the study’s primary goal is to assess the digitalization solutions that enhance Amazon’s warehouse operations. For this work, a qualitative research methodology was employed, and data was gathered via SWOT analysis and semi-structured interviews. Seven Amazon employees involved in warehouse operations participated in the study. Warehouse management systems (WMS), RFID technology, Internet of Things (IoT)-enabled sensors, robotics (such Kiva robots), machine learning, and cloud platforms are some of the important digital tools utilized in Amazon’s warehouse operations. The implementation of these technologies led to a 99% increase in inventory accuracy, a 60% reduction in error rates, a 30% decrease in labor dependency, and a 25% reduction in order picking time. In addition, online data tracking was enhanced, particularly using RFID and IoT tools, which increased decision-making speed and accuracy. Staff training issues, incompatibility with outdated systems, and brief technological hiccups were among the obstacles to digitization. However, the total advantages of modernizing an organization and integrating new technology into its structure outweigh all of these, according to research participants. Under headings like artificial intelligence and machine learning, the reviewers claim that the digitization process has significantly improved a company’s warehouse operations.
- Podem as plataformas digitais serem transformadas pela inteligência artificial?Publication . Gouveia, Luis Borges; Pinto de Sá Moscoso Marques, Maria Beatriz; Marques dos Santos, Miguel NunoAs plataformas digitais (PD) são fundamentais para a exploração dos ecossistemas digitais que suportam a atividade humana. Seja em atividades individuais ou organizacionais, de valor ou lazer, o uso das PD é, atualmente, quase universal. Elas oferecem alternativas mais cómodas, rápidas e económicas, com funcionalidades que as tornam muitas vezes a melhor ou mesmo única opção. A inteligência artificial (IA) está a revelar-se como uma tecnologia competitiva, integrando-se em diversas ferramentas digitais. A IA proporciona automação mais rápida, económica e conveniente, seguindo o já ocorrido com as PD. Como resultado, é expectável um aumento significativo no uso de ferramentas baseadas em IA. Tanto os utilizadores como os próprios proprietários das PD investem na adoção de ferramentas IA. Por sua vez, a recente legislação da União Europeia (UE) visa regular as PD e prevenir seu uso abusivo, garantindo um uso seguro e responsabilizando os prestadores de serviços digitais. A regulamentação das plataformas e serviços digitais, juntamente com o Regulamento dos Serviços Digitais e o Regulamento dos Mercados Digitais, procura harmonizar antigos e novos regulamentos. Esta estratégia da UE tem por objetivo a criação de um espaço digital que proteja os direitos fundamentais dos utilizadores dos serviços digitais. Neste contexto, propõe-se uma discussão sobre o impacto da IA e como as inovações associadas ao seu uso nas PD podem ser afetadas pela regulação da UE. Da combinação de IA e PD resulta uma transformação significativa na forma como interagimos com a tecnologia, mas também levanta questões importantes sobre segurança, privacidade e responsabilidade.

- Tourism, sustainability and innovation: low-tech roots and high-tech horizonsPublication . Safaa, Larbi; Leal Filho, Walter; Perkumienė, Dalia; Dinis, Maria Alzira Pimenta; Safaa, Larbi; Leal Filho, Walter; Perkumienė, Dalia; Dinis, Maria Alzira PimentaToday, tourism offers a privileged perspective to explore the relationships between sustainability, innovation, and inclusion. This volume, Tourism, Sustainability and Innovation: Low-Tech Roots and High-Tech Horizons (part of the World Sustainability Series), includes contributions from scholars with 23 different nationalities (Belgium, Bulgaria, Cameroon, China, Finland, France, Germany, Hungary, Japan, Kazakhstan, Latvia, Lithuania, Morocco, Poland, Portugal, Qatar, Saudi Arabia, Spain, Taiwan, Tunisia, Turkey, Ukraine, United Kingdom). This diversity reflects the richness of perspectives included in the book, encompassing around fifteen different case studies and country contexts, analyzed through a variety of cultural, economic, and institutional lenses. Collectively, the chapters open a dialogue on how to reconcile practices deeply rooted in local territories with the emerging horizons shaped by new technologies. Central to the theme of Tourism, Sustainability and Innovation: Low-Tech Roots and High-Tech Horizons is a creative tension: how do we embrace the authenticity of local practices, traditional “know-how” and cultural resources, often carriers of resilience and ‘low-tech’ sustainability, while purposely bringing in the digital, intelligent, automated solutions that are transforming tourism today? The difficulty is not to play past against future, but to think about how innovation can keep hold of tourism’s human, social and territorial roots, and at the same time, open new possibilities. From this point of view, notably, we can ask: How can tourism experiences be meaningfully inclusive? How can digital transformation add to our focus on sustainability? And how can technology be deployed not for itself alone, but as a lever for destinations, communities, and stakeholders across the industry? This book is important because it redefines innovation in tourism beyond just high-tech solutions. It promotes a balanced approach that values basic "low-tech" sustainable practices, like community-based models and resource conservation. At the same time, it shows the rôle of advanced "high-tech" tools, such as AI and big data. By connecting this often-neglected range, it offers a complete and practical framework for building a truly sustainable tourism sector. It serves as a necessary guide to ensure that innovation supports the larger goals of environmental responsibility, social fairness, and lasting resilience. The book is structured around six main sections, each reflecting a key thematic axis of contemporary tourism research. The first section, Vulnerability, Rights and Sustainable Pathways in Tourism, highlights institutional transitions, multi-level governance, legal protections, and the need for more equitable and resilient destinations. The second section, New Trends in Technology, Digitalization and Innovation in Tourism, examines neuro-tourism, smart technologies, digital platforms such as Booking.com and Instagram, public digitalization, logistics optimization, and issues related to data protection, privacy and ethics. The third section, Tourism Destinations: Image, Perceptions, and Governance, explores destination image, emotional connections, social media dynamics, urban environments, and the e-reputation of cities including Essaouira, Marrakech, Makkah and Jeddah. The fourth section, Tourism, Heritage and Cultural Resources, focuses on cultural and intangible heritage, creative and art tourism, gastronomy, value systems in online reviews, and legal perspectives on medical tourism. The fifth section, Entrepreneurship, Career Dynamics and Organizational Transformation in Tourism, addresses community participation, professional trajectories in the hotel sector, digital transformation in organizations, and legal dimensions of transportation and accommodation. Finally, the sixth section, Tourist Experiences and Behavioral Perspectives, examines rural tourism experiences, tourist expenditures, senior well-being, urban mobility, leisure infrastructures, and issues of personal data protection in the age of artificial intelligence.
- Trajectories of circular economy in cities: key patterns and emerging pathwaysPublication . Aina, Yusuf; Almulhim, Abdulaziz I.; Salami, Babatunde Abiodun; Swart, Julia; Abubakar, Ismaila Rimi; Dinis, Maria Alzira Pimenta; Sharifi, AyyoobUrbanisation and escalating resource pressures have intensified the need for systemic approaches to sustainable development, positioning the circular economy (CE) as a critical framework for cities. This study reviews academic literature to examine current trends, challenges, and forward-looking strategies for CE implementation in urban contexts. Using a search process aligned with the PRISMA protocol, 668 peer-reviewed articles were analysed through inductive content analysis. The findings reveal that CE practices in cities are increasingly shaped by global sustainability agendas, particularly in relation to SDGs 9 to 12. The analysis identifies eight thematic clusters that characterise urban CE pathways: urban planning and the built environment, energy and mobility systems, waste and resource management, water and urban agriculture, citizen engagement, governance and regulation, technological innovation, and socio-cultural transformation. A conceptual framework integrating eight thematic clusters is presented, illustrating how cities transition from linear to circular systems through policy alignment, digital innovation, and multisectoral collaboration. Case studies from global urban centres illustrate strategies ranging from smart infrastructure and circular procurement to social inclusion and localised production, all of which enable CE advancement. These findings reinforce the view of CE as a multidimensional approach capable of fostering urban resilience, environmental stewardship, and inclusive economic growth.
