A systematic literature review on greenwashing and its relationship to stakeholders: state of art and future research agenda
Publication . Santos, Célia; Coelho, Arnaldo; Marques, Alzira
The interest in greenwashing has grown in recent decades. However, comprehensive, and systematic research concentrating on the evolution of this phenomenon, specifically regarding its impacts on stakeholders, is still needed. The main purpose of this study is to provide an overview and synthesis of the existing body of knowledge on greenwashing, through a bibliometric study of articles published up to 2021, identifying the most relevant research in this field. Special attention is given to the latest articles that link greenwashing to stakeholders, identifying gaps and future research opportunities. A bibliometric analysis and literature review was performed on 310 documents obtained from the Web of Science database, using the VOSviewer software program. This article identifies the most influential aspects of greenwashing literature (authors, articles, journals, institutions, and keyword networks). The most recent articles on the effect of greenwashing on stakeholders were also analyzed, which made it possible to identify trends, gaps, and opportunities for future research. These topics include greenwashing impacts on branding, consumer attitudes and intentions, mainly on purchase behavior, B2B relationships and the definition of taxonomy for greenwashing, considering the different practices. This study offers a thorough analysis on the state-of-the-art, as well as a closer look at the impacts of greenwashing on various stakeholders, providing a list of suggestions for future research.
Regional Dynamics and Economic Sustainability of Mariculture Firms in Portugal: A Financial Performance Analysis
Publication . Santos, Eleonora
This study provides a comprehensive analysis of the financial performance of aquaculture firms in Portugal from 2013 to 2022, considering regional, age, and size dynamics. Using financial data from the ORBIS database, key performance indicators are calculated to assess the industry’s economic sustainability, regional disparities, and firm-level effects. The analysis reveals insights into the resilience of aquaculture firms in navigating economic challenges, such as the COVID-19 pandemic, and highlights the importance of tailored policy interventions to support regional development and industry competitiveness. Age trends show the influence of industry experience on financial performance, with older firms demonstrating higher turnover and profitability. Size trends indicate the advantages of economies of scale for larger firms, while smaller firms exhibit agility and innovation. This study contributes to the understanding of aquaculture economics in Portugal, providing valuable implications for policymakers, industry stakeholders, and aquaculture firms. By considering regional, age, and size dynamics, stakeholders can develop comprehensive strategies to enhance the sector’s long-term sustainability and resilience in an increasingly dynamic market environment. Recommendations are provided for policymakers to support regions with lower performance metrics, enhance infrastructure development, and promote workforce productivity to foster balanced economic growth across the aquaculture sector in Portugal.
Renewable Energy and Socio-Economic Transformation: Three Case Studies
Publication . Santos, Eleonora
Portugal’s renewable energy transition plays a pivotal role in addressing climate change, enhancing energy security, and promoting sustainable development. This study examines the socio-economic impacts of renewable energy policies in Portugal from 2014 to 2022, with a focus on financial performance, employment trends, and gender equity. Utilizing financial assessments from the Orbis database and input–output analysis, the research examines three companies—EDP, E-Redes, and Logical Gravity—classified under NACE Rev. 2 code 3513. The study finds that investments in renewable energy improved profitability and solvency, especially during recovery phases, reflecting the sector’s financial resilience. Larger firms like EDP experienced employment growth, while smaller firms faced more volatility, highlighting the need for targeted support. Despite progress, gender disparities and pay gaps persist, underscoring the need for gender-sensitive policies. This research provides valuable insights for policymakers seeking to ensure a just and sustainable energy transition, emphasizing strategic investments, workforce adaptation, and inclusivity.
Effects of non-zero phase harmonics on inductions machines and coupled mechanical loads
Publication . Oliveira, Filipe Tadeu; Peláez, Gerardo; Donsión, Manuel P.; Iwaszkiewicz, J.; Perz, J.
The presence and effect of harmonics in power systems is widely known, but some of its effects are still only partially studied and addressed in existing works. Traditionally, power system harmonics were nearly always not phase-shifted from the fundamental sine wave, and therefore the effect of the phase was not considered. This paper will address the influence of such harmonic content, with non-zero phase, in the behaviour of an induction machine and its mechanical load, namely in mechanical vibrations produced and speed stability. While mechanical vibrations are intrinsically present on rotating machines, both electrical and mechanical parameters can have a strong influence in their severity. This being a broad topic of research, this paper intends to show a preliminary approach destined to validate some of the starting points set for the development of further work.
Tourist Preferences in Latin America
Publication . Santos, Eleonora; Carvalho, Milena; Martins, Susana; Carvalho, Ana Branca; Castro, Maria João; Mesquita, Anabela; Silva, Paulino
In today's era of digital transformation, understanding tourism preferences is crucial for enhancing the travel experience. The way travelers get, analyze, and apply information to plan their trips has been completely transformed by information and communication technologies (ICTs). Features like accessibility, attractions , amenities, and prices influence travelers' choice regarding their destination and according to the Information Search Theory, travelers look up a lot of information in order to lower uncertainty and improve the quality of their decisions. This study examines the intricate interplay of factors influencing tourist preferences in Latin America, focusing on the role of hotel ratings, location, attractions, and accessibility. Drawing on regression analysis of data from Booking.com across six Latin American countries , including Mexico, Peru, Argentina, Chile, Colombia, and Brazil, the research identifies distinct tourist profiles and their preferences. Novel findings include a preference for lower-rated hotels among certain segments, a trade-off between accessibility and destination characteristics, and a prioritization of accessibility over the diversity of attractions for some travelers. These insights have significant implications for tourism management, suggesting targeted marketing strategies, product development initiatives, infrastructure investments, and collaborative partnerships to enhance the overall visitor experience and promote sustainable tourism development in the region.
