- Analysis of Power Quality Disturbances in Industry in the Centre Region of PortugalPublication . Moreira, Licinio; Leitão, Sérgio; Vale, Zita; Galvão, João; Franco Marques, Pedro JoséPower quality issues have taken a more prominent role in power systems over the last years. These issues are of major concern for energy customers, primarily for customers with a widespread use of electronic devices in their manufacturing processes. Even though the quality of service is increasing, customers are becoming more demanding of the energy provider. This research aims to provide some industrial managers the technical support in deciding of investments in the mitigation of power quality disturbances, such as the use of less sensitive devices or the use of interface devices (UPS, DVR...) In order to recommend an appropriate solution, the problem is characterized. The technical and economic influences of the PQ disturbances in the manufacturing processes are assessed resorting to power quality audits in the customer facilities. This research covered a significant number of facilities in several industrial activities.
- Building Strategic Capabilities in Brazilian FirmsPublication . Fleury, Maria Tereza Leme; Calixto, Cyntia Vilasboas; Frias Pinto, Cláudia Sofia; Fleury, AfonsoIn this chapter, we highlight the strategic capabilities that have enabled six Brazilian companies to achieve competitive advantage. We selected firms from different industries and stages of internationalization in order to show a broad perspective of local and international successful firms. WEG and Fanen developed technological capabilities associated to both world-class manufacturing and product innovation, whereas Stefanini and Integration have consolidated knowledge about servicing emerging markets. Grendene’s production and operations are its key capabilities for international operations through exports, while innovative design and processes support their strategy in the local markets. The key capabilities of Dr.Consulta are entrepreneurship and innovation. In sum, due to highly turbulent institutional and economic environment, Brazilian firms have had to develop some specific capabilities, especially those related to financial management and organizational flexibility.
- Database Marketing Process Supported by OntologiesPublication . Mota Pinto, Filipe; Marques, Alzira; Santos, Manuel FilipeThe dramatic explosion of data and the growing number of different data sources are exposing researchers to a new challenge - how to acquire, maintain, and share knowledge from large databases in the context of rapidly applied and evolving research. This paper describes research on an ontological approach for leveraging the semantic content of ontologies to improve knowledge discovery in databases. We analyze how ontologies and knowledge discovery process may interoperate and present our efforts to bridge the two fields, knowledge discovery in databases and ontology learning for successful database usage projects.
- Financial Structure, Product Market Decisions and Default Risk in an Asymmetric DuopolyPublication . Costa, Magali; Pires, Cesaltina PachecoFinancial and output market decisions are crucial to the success or failure of an organization. In this paper we analyze the equilibrium default risk in a two-stage duopoly model with an uncertain environment, where firms decide their financial structure in the first stage of the game and decide their quantities in the second stage of the game. Using numerical analysis, we analyze the impact of changing the asymmetry in the two firms' marginal costs on the equilibrium default risk. Our results show that as a firm becomes less efficient it is optimal to reduce its debt level and the quantity produced. The reverse is true for the more efficient firm. This behavior implies that although higher marginal cost leads to lower profits, the less efficient firm reduces its default probability due to a more cautious behavior in the financial and product market. © Springer International Publishing Switzerland 2015.

- The Influence of Business Cycles on Corporate Performance: Evidence from Outdoor TourismPublication . Santos, Eleonora; Abreu, António; Pinto, Agostinho Sousa; Carvalho, Milena; Martins, SusanaTourism contributes substantially to economies and employment opportunities. In recent years, sustainable tourism has gained prominence, seeking to harmonize economic growth with environmental preservation and social equity. This concept revolves around minimizing tourism’s environmental impact while maximizing local community benefits. Consequently, assessing the economic sustainability of tourism firms becomes imperative for destinations aspiring to cultivate sustainable tourism practices, particularly in nature-based, cultural, and nautical activities. This study delves into the economic sustainability of outdoor tourism firms in Portugal, encompassing nature-based, cultural, and nautical activities, from 2013 to 2022 across diverse business cycles. Utilizing data from the National Tourism Registry and the SABI database, we scrutinize profitability and financial structures. Our findings underscore essential insights. Nature/adventure firms struggle to maintain consistent positive returns on assets, while cultural and nautical firms exhibit variable profitability linked to economic conditions. Nature/adventure firms display relatively strong current liquidity, hinting at potential financial resilience during economic downturns. Cultural firms consistently exhibit higher financial autonomy, indicative of distinct financial management practices. Debt ratios vary significantly among firms, reflecting diverse financing strategies and risk profiles. These findings hold implications for outdoor tourism sector managers and policymakers. Managers must prioritize risk management, financial strategies, and financing approaches to bolster financial resilience and long-term sustainability. Policymakers can offer targeted support and incentives to mitigate the adverse effects of business cycles, safeguarding the sector’s enduring viability.
- The Use of Social Networks as a Strategic Tool: The Case of Cuca Monga Discos and Its Presence on TikTokPublication . Lobo, Rafaela; Martins, Susana; Carvalho, Milena; Abreu, António; Castro, Maria João; Santos, Eleonora; Branca, AnaThe increased presence of brands and organizations on digital social networks has led to the need to understand and characterize their strategies and engagement with the public. The present study is an exploratory-descriptive investigation based on a literature review and the analysis of alternative metrics with the general objective of knowing how the publisher Cuca Monga Discos used TikTok between 2019 and 2022. It is assumed that engagement and participation are essential for the cultural industry hence the importance of promoting an environment of interaction between actors on social networks. It is concluded that the publisher uses Tik Tok and interactivity strategies and that adopting strategies that actively encourage followers to interact more will be beneficial.
- Tourist Preferences in Latin AmericaPublication . Santos, Eleonora; Carvalho, Milena; Martins, Susana; Carvalho, Ana Branca; Castro, Maria João; Mesquita, Anabela; Silva, PaulinoIn 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.
