Toxic Leadership and Internal Marketing: the effect of the HSP trait on satisfaction and engagement
Publication . Lin, Patrícia Cai; Martinez, Luísa M.; Ramos, Filipe R.
Leadership fosters trust, engagement, and performance. Strong manageremployee relationships enhance productivity and security, while positive ties improve performance. Leadership sensitivity is crucial for empathy, but toxic
leadership harms employees and performance, requiring urgent action. Toxic leadership negatively impacts employee satisfaction and engagement. Harmful traits like intimidation and manipulation alienate employees, weakening team
performance. However, there is a lack of research on its specific effects. Understanding these consequences is essential for aligning internal marketing strategies and fostering a healthier work environment, particularly for highly sensitive people (HSP). A quantitative methodology was adopted, through an online questionnaire, disseminated through the Prolific platform. The experimental design follows a between-subject approach, with two questionnaire versions, using a
simulated scenario testing the leadership effect (toxic leadership scenario vs. nontoxic leadership scenario). The dependent variables are employee satisfaction and engagement, and the independent variable is toxic leadership. The HSP trait is the moderating variable. Using a quantitative methodology, the study tested the effects of toxic versus non-toxic leadership on satisfaction and engagement, with a particular focus on those with highly sensitive traits (Aron & Aron, 1997). While significant differences were found between leadership conditions, the moderating role of the HSP trait was not confirmed. Furthermore, these findings could reduce turnover and cultivate a more harmonious work culture, emphasizing the need to study the effect of toxic leadership on highly sensitive people, this research aims to
address gaps in empirical literature regarding toxic leadership’s impact on employee satisfaction and engagement, especially for HSPs.
The impact of crunchyroll´s service quality on its brand image in the portuguese anime streaming market
Publication . Elyadini, Sami; Figueiredo, Ronnie
This study investigates the influence of Crunchyroll’s service quality dimensions on its brand image within the Portuguese anime streaming market. Identifying how service characteristics of distinct platforms influence consumer opinions will drive successful brand strategy and competitive separation in the anime market. The research analyses four essential variables, which include content quality alongside platform usability, customer support quality, and pricing/subscription model, to determine their effects on Crunchyroll's brand image perception. This research utilized a quantitative approach through structured surveys sent to Portuguese Crunchyroll user participants. The researchers used descriptive statistics, reliability analysis, and multiple regression techniques to evaluate data and verify variable relationships, as well as their significance and strength. The study shows that brand image receives a positive and significant impact from each service quality dimension, yet content quality and platform usability demonstrate the most powerful predictive capability. The main reasons users liked Crunchyroll stemmed from its localized anime selection and diverse offerings, along with its user-friendly interface. The evaluation of customer support and pricing strategies produced moderate results in comparison to the other variables. The study demonstrates that customers form positive brand associations because of affordable pricing combined with flexible plans and fair price structures. Service-based brand image evaluation of Crunchyroll results in both functional and experiential attributes that support the consistent delivery of quality services, optimized platforms, and strategic pricing within digital streaming markets. The research offers practical recommendations for streaming service providers to build brand reputation and maintain customer retention in their regional customer bases. The study provides new insights into service quality research and brand image studies in digital media services while establishing evaluation methods for consumer-brand relationships in subscription-based platforms.
FROTA COSTEIRA DE CERCO CARACTERIZAÇÃO TECNOLÓGICA E TIPOLOGIAS DE EMBARCAÇÕES
Publication . Parente, Joaquim; Feijó, Diana; Silva, Alexandra; Instituto Português do Mar e da Atmosfera, I.P.
It is intended to characterize coastal seine vessels with an active license in 2016, operating in ICES zone 9a, depending on the shape of the hull and structures on the deck, as well as on the type of equipment used for hauling and handling the seine gear on board. The grouping of vessels into typologies will depend on that characterization and on the degree of modernization of the vessels. Most vessels have a high degree of modernization of the deck, promoting the speed of fishing operations and improving the quality and safety of work on board. Currently, there are few vessels operating
without a purse line reel or that do not have at least one crane to facilitate the handling of cargo and aid in fishing maneuvers, which was very infrequent to observe 15 years ago. The placement of a gantry on the stern deck, aims to facilitate maneuvers with the seine skiff and to improve the working conditions and safety of the crew, being more common in larger vessels due to the larger spaces on deck. Five typologies were identified in the current composition of the coastal seine fleet operating off the Portuguese mainland coast, each one presenting different degrees of modernization. The greater the size of the vessel, the greater will be the deck space available for the deployment of structures and fishing equipment that increase both the vessel's fishing power and the comfort and safety of the crew on board.
Perceived authenticity of virtual vs human in the context of influencer marketing
Publication . Yé, Tainara Pereira; Pacheco, Natália
This study investigates the perceived authenticity of Virtual Influencers (VIs) compared to Human Influencers (HIs), addressing the research question: when might Virtual Influencers be perceived as more authentic than their human counterparts? This comparison is made across various types of products and services. Adopting a qualitative approach, semi-structured interviews were conducted with 14 social media users from diverse international backgrounds. The main results indicate that while VIs demonstrate potential in specific niches such as technology and visually-driven products like luxury items, fashion, and tourism, HIs are generally perceived as more authentic owing to their capacity for genuine emotional expression, lived experiences, and relatable personal narratives. Participants primarily linked authenticity to an influencer's honesty, consistency, and real-life product use, which in turn significantly influences purchase intentions, with a strong current preference for HIs, even though VIs human-likeness can enhance initial relatability despite underlying skepticism. Furthermore, theoretical and managerial implications are discussed at the end of this dissertation.
ESCALA DE MATURAÇÃO MACROSCÓPICA E MICROSCÓPICA DO VERDINHO (Micromesistius poutassou)
Publication . Gonçalves, Patrícia; Costa, Ana M.; Ferreira, Ana Luísa; Resende, Adelaide; Carmo Nunes Silva,; Abreu, Paula; Pechirra, Pedro; Instituto Português do Mar e da Atmosfera, I.P.
Blue whiting (Micromesistius poutassou) is a mesopelagic teleost, of the gadidae family and widely distributed along the Atlantic North and Mediterranean. On the Portuguese coast, the main spawning season for this species occurs between January and March. At IPMA, the biological sampling of blue whiting is carried out regularly, in samples from discards collected onboard commercial vessels, fishing landings (Peniche, Matosinhos e Vila Real de St. António) and from scientific research surveys. Regarding the reproductive cycle, the identification of the maturity stages is made macroscopically during biological sampling. The maturity stage key currently in use at IPMA and applied to blue whiting is of the one suggested by Godinho et al. (2001), which was developed only based on macroscopic observations and descriptions, without microscopic validation. This study aims to microscopically describe the morphology of the gonads throughout the reproductive cycle for blue whiting, to validate and intercalibrate the
macroscopic identifications based on histology and also to propose a new macroscopic maturity stage key taking into account the microscopic and macroscopic characteristics of the different stages from the sexual development cycle. Keywords: Blue whiting, Micromesistius poutassou, histology, macroscopic identification, microscopic maturity scale, macroscopic maturity scale.
