- Marketing in the public sector - benefits and barriers: a bibliometric study from 1931 to 2020Publication . Matos, Nelson; Correia, Marisol B.; Ramón Saura, José; Reyes-Menendez, Ana; Baptista, NunoThe global economy has brought economic and social changes that have led organizations to extend their vision beyond consumer and business markets. Particularly, in the marketing of public sector (MPS), the extant theoretical foundations require more comprehensive investigations not only into the main topics researchers have looked into the past, but also into the new challenges they will face in the future. Thus, the purpose of this study is to provide a thorough a bibliometric overview of the theoretical framework and to identify benefits and barriers of marketing in the public sector. We provide an overview of the theoretical framework and identify the benefits and barriers of marketing in the public sector through a bibliometric study. To achieve this objective, a systematic literature review was conducted of 3926 articles from 1931 to 2020. The results allowed the identification of four main theoretical clusters: educational, public health, social economics and urban politics. It also offered benefits and barriers in the context of MPS. Conclusions and implications to the academia and managers are drawn. Future research opportunities are also provided.
- 2019 world of shipping Portugal. An international research conference on maritime affairs editorial “Leading the shipping industry into the future”Publication . Paixão Casaca, Ana Cristina; Loja, M.A.R.Background, the context and purpose of the study: The current Editorial addresses the evolutionary path of the shipping industry. It mentions its role throughout the years, identifies the leading market segments, refers to the different operational modes due to the inherent nature of the cargoes they carry and lists some trends that appear to have been shaping the maritime industry. Within the scope of this background, the Editorial claims that all maritime market segments face the same future challenges and lists a range of international legislation released by the International Maritime Organisation which industry players must comply with. Findings, the main results: Not/aplicable. Conclusions, brief summary and potential implications: The Editorial concludes by stating that the maritime industry will benefit from the implementation of innovative solutions and further claims that wrong decisions will have severe impacts on the finances of the shipping companies and the environment. Moreover, it presents in a brief way the papers published in this Special Issue, which were selected among the ones presented at the 2019 World of Shipping Portugal, an International Research Conference on Maritime Affairs, 21–22 November 2019, that took place at Hotel Riviera, in Carcavelos, Portugal.
- Ternary mixes of self-compacting concrete with fly ash and municipal solid waste incinerator bottom ashPublication . Simões, B.; Raposeiro Da Silva, Pedro; Silva, R.V.; Avila, Yoleimy; Forero, J. A.This study aims to evaluate the potential of incorporating fly ash (FA) and municipal solid waste incinerator bottom ash (MIBA) as a partial substitute of cement in the production of self-compacting concrete mixes through an experimental campaign in which four replacement levels (i.e., 10% FA + 20% MIBA, 20% FA + 10% MIBA, 20% FA + 40% MIBA and 40% FA + 20% MIBA, apart from the reference concrete) were considered. Compressive and tensile strengths, Young's modulus, ultra-sonic pulse velocity, shrinkage, water absorption by immersion, chloride diffusion coefficient and electrical resistivity were evaluated for all concrete mixes. The results showed a considerable decline in both mechanical and durability-related performances of self-compacting concrete with 60% of substitution by MIBA mainly due to the aluminium corrosion chemical reaction. However, workability properties were not significantly affected, exhibiting values similar to those of the control mix.
