- Future Perspectives on ElectrospinningPublication . Mitchell, Geoffrey R.; Sperrin, MalcolmAlthough the origins of electrospinning date back over 100 years, it is intense activity in the last 21 years which has led to considerable improvements in our knowledge of electrospinning and the broad-ranging opportunities for commercial application. The recent development of melt electrospinning provides a new additive manufacturing tool, providing routes to structures from nanometres to millimetres. Here, we consider where this rollercoaster of a topic is heading and its future prospects.
- Green Marketing and Green Brand – The Toyota CasePublication . Simão, Lídia; Lisboa, AnaThe main aim of this study is to contextualize sustainability and call for its consideration in firms’ management, namely via green marketing and green brand. Although the concept of sustainable development appeared in the 1970s, only recently has it been incorporated by firms. Development, to be sustainable, has to satisfy the needs of current generations, without compromising the ability of future generations to satisfy theirs. This requires a balance in managing social, economic and environmental aims, both current and future. Given the increasing evidence of environmental problems, the awareness of the need for sustainability has been expanding, at the individual and at the corporate level. Environmentally responsible firms obtain multiple benefits, such as cost reduction (due to the lower resource consumption, such as water or energy), profit increase (from recycling and residuals reuse), production process enhancement (given the cleaner and more efficient technologies), corporate image upgrading, improvement of brand awareness and value as well as performance. Oppositely, firms associated to non-sustainable actions are impaired in those areas. In the scope of a green strategy, a green brand obtains attributes and benefits related to the reduction of the brand’s environmental impact. As such, it should promote the perception of an environmentally healthy brand and disclose such benefits to the more environmentally aware consumers. We present the case of Toyota, a brand with patent and acknowledged efforts in what regards sustainability. It is a worldwide reference of corporate responsibility and of a successful use of green marketing. The brand’s challenge to reach important environmental goals until 2050, demonstrates its commitment and endeavor in multiple crucial aspects of sustainability management. Therefore, Toyota is in a prominent position as a “global green brand”.
- How knowledge sharing mediates the effects of internal marketing on customer orientationPublication . Espírito Santo, Pedro Manuel do; Ferreira, Vítor Hugo Santos; Marques, Alzira Maria AscensãoA growing body of research has demonstrated the growing importance given to two areas of business management: internal marketing and knowledge management. Nevertheless, these seldom areas are considered together. This paper explores the importance of knowledge sharing as a mediating variable in the relationship between internal and external marketing. Thus, our research presents an investigation model where the influence of tacit knowledge sharing and explicit knowledge sharing are presented. The data of this research was collected from the employees of a company in the logistics sector, through a face-to-face questionnaire. The proposed research hypotheses were tested empirically through structural equation modeling (PLS-PM) with a bootstrapping procedure. The results demonstrate that internal marketing has a positive effect on knowledge sharing and, consequently, on customer orientation. In this sense, through this paper, managers can verify the importance of knowledge sharing (tacit and explicit) in leveraging the effects of internal marketing in customer orientation.
- The influence of knowledge management on the result of innovation of companies in the mold industriesPublication . Ferreira, Vítor Hugo Santos; Marques, Alzira Maria Ascensão; Espírito Santo, Pedro Manuel do; Silva, Sara Fernandes daIn today's business world, knowledge and innovation are key factors for the success of organizations. Knowledge stock alone does not generate a competitive advantage to companies, but the way it is used might create it. It is through the wide network of relationships that involves the organization that innovations emerge. These two concepts are intertwined, since for the innovation process to be successful, there must first be an effective knowledge management, which involves knowledge acquisition, application and sharing. In this context and based on a sample of 36 companies in the mold making sector in Portugal (one industry where Portugal is the 8th top producer in the world), a confirmatory research work was carried out with the aim of studying the impact of knowledge management on innovation performance. For this purpose, we used a quantitative methodology based on a survey. Through the estimation of a structural equations model, using SmartPLS software, we found that knowledge acquisition has a positive influence on knowledge sharing, which in turn is positively reflected in its application, which positively impacts innovation in performance in Portuguese plastic injection mold making companies-these results are in line with similar studies carried out in different contexts. Consequently, knowledge, considered as an intangible asset, must be managed effectively and efficiently, in order to create value through innovation, a determinant of competitiveness in an activity sector that creates customized solutions for its customers. Despite of the small sample size, these results highlight the importance of effectively managing the acquisition.
- Stakeholder Differences in Valued Hotel Green PracticesPublication . Julião, Jorge; Monteiro, Inês; Gaspar, Marcelo; Trindade, Maria AliceThis paper aims to compare the perceptions of hotel customers and hotel staff regarding the value of green hotel attributes. By examining both stakeholder groups, the study addresses a gap in sustainable hospitality research, which largely overlooks employee perspectives in favour of customer preferences. An exploratory, cross-sectional survey was conducted using structured questionnaires, administered to hotel guests (n = 307) and hotel staff (n = 89) in Porto, Portugal. Respondents rated 15 green hotel attributes using a five-point Likert scale. Demographic data were also collected to analyse perceptual differences across gender, age, income, and education. The results revealed that both customers and staff exhibited environmental awareness, though their prioritisation of specific green practices differed. Customers tended to value visible environmental measures, such as recycling bins, energy-saving light bulbs, and renewable energy signage, while staff placed greater emphasis on operational sustainability aspects, including low-flow plumbing fixtures, refillable soap dispensers, and durable goods used in service areas. These differences reflect the stakeholders’ distinct roles and experiences within the hotel ecosystem. This study enriches the discourse on sustainable hospitality by providing a dual-stakeholder analysis of green hotel attributes using a shared evaluative framework. The findings offer practical insights for hotel managers aligning sustainability strategies with the expectations of both guests and employees, supporting more effective and inclusive green implementation in the lodging sector.
- Thermal analysis of an extrusion system of a 3-D bioprinterPublication . Ribeiro G.S.; Silva J.V.L.; Freitas D.; Bartolo P.; Almeida, Henrique de Amorim; Silveira Z.C.This work presents a finite element thermal analysis of a 3-D bioprinter desktop based on Fused Deposition Modeling (FDM) with applications on tissue engineering, designed by the Centre for Rapid and Sustainable Product Development - Leiria, Portugal. The purpose of this work it is compare three possibilities of temperature control of the machine during the extrusion process, considering the use of a biodegradable polyester (Polycaprolactone - PCL) as raw material. The first two configurations simulate approaches typically adopted in an attempt to keep the polymer as close as possible to 80 °C and prevent its premature solidification at a critical point. The third configuration considers a hypothetical material substitution to enhance thermal conductivity. The results indicate that the first two configurations are not sufficient to achieve total control of the polymer temperature. However, the third configuration show a significant potential to improve the thermal control of the extrusion process.
