- Design-manufacturing coordination: proximity, integration and beyond, towards omnishoringPublication . Abecassis-Moedas, Céline; Moatti, ValérieRecent research argues that when innovation is embedded in the manufacturing process, design and manufacturing need to be integrated and geographically close to secure current and future innovation. However, process-embedded innovative industries such as fashion (Pisano & Shih, 2012) have massively outsourced and/or offshored for decades. Our research aims to understand how innovative firms in the fashion industry manage design-manufacturing coordination in terms of proximity and integration. Examining 18 European fashion firms, our work uses an abductive approach to understand how firms manage their design-manufacturing coordination and specifically the role played by proximity and integration in such coordination. The analysis reveals that there is a range of coordination modes that go beyond geographical proximity and vertical integration. We also argue that proximity and integration are complex notions and not independent options. Finally, we demonstrate the concept of omnishoring, as coordination strategies are often managed simultaneously and complement each other.
- A multi-criteria approach to decision making in broadband technology selectionPublication . Araújo, Marco; Ekenberg, Love; Danielson, Mats; Confraria, JoãoA new European Union regulatory framework for the telecom sector has been under a process of transposition to national laws by its member states that should have been completed by the end of 2020, notwithstanding some delays. A core purpose of the regulatory framework is to guarantee that most citizens will have access to very fast Internet connections, capable of 100 Mbps download link speed, regardless of where they live. According to this new framework, in areas where the market does not deliver, governments are to launch public tenders for the deployment, maintenance, and operations of network infrastructure as well as services, and public funds should be used to support the deployment of these broadband networks in less densely populated areas. Needless to say, public tenders of this nature are subject to different criteria when it comes to candidate evaluation. In this paper, we present a decision model for the selection of operators to deploy and maintain broadband networks in scarcely populated areas, taking into consideration infrastructure costs, the technical quality offered by the solutions, and the credibility of the candidates. We suggest an integrated multi-stakeholder multi-criteria approach and demonstrate how it can be used in this complex area and find that in the example provided, taking a relevant set of criteria into the analysis, optical fibre networks hold much higher chances to be used in these public tenders compared to networks based on the broadly favoured 5G technology.
- Validity and reliability of the Portuguese version of the rapid estimate of adult literacy in dentistry - REALD-29 PTPublication . Costa, Hélder; Amaral, Odete; Duarte, João; Correia, Maria José; Veiga, Nélio; López-Marcos, Joaquín FranciscoBackground: Health literacy is a main factor in health for its improvement, allowing the individuals to have a greater capacity to engage and participate in collective health promotion actions. The assessment of functional health literacy to determine the ability that each individual has to understand basic health information is essential. The aim of the present study was to translate and perform the cross-cultural adaptation of the Rapid Estimate of Adult Literacy in Dentistry (REALD-30) to Portuguese language and test the reliability and validity of this version. Method: The REALD-30 in the Portuguese language (REALD-29 PT) was applied to a group of individuals that participate in the program Atividade Senior, developed by the municipality of Viseu, Portugal. The final sample was composed by 206 participants that accepted responding to the questionnaire and to the REALD-30 Portuguese version (REALD-29 PT). Translation and cultural adaptation of the questionnaire and the statistical validation was accomplished in order to complete the process and obtain the REALD-29 PT. Results: The REALD-29 PT presented good internal reliability. Cronbach’s alpha ranged from 0.89 to 0.90 when words were deleted individually. The analysis of test-retest reliability revealed excellent reproducibility. We can verify that the REALD-30 scale for assessment of oral health literacy among older adults presents an acceptable internal consistency, with a global Cronbach´s alpha of 0.894. Conclusions: The REALD-29 PT scale can be applied to assess oral health literacy among older Portuguese adults, presenting an acceptable internal consistency and is validated to assess oral health literacy and is crucial in epidemiological studies.
