- This article describes the fabrication of MgF2 and MgO thin-film-based optical filters and compares the optical transmission of the filters over UV. The MgF2 thin-films were deposited by use of an e-beam technique and their optical properties were characterised by ellipsometry. The effect of substrate temperature on the optical properties was studied. The MgF2 optimum refractive indices were obtained with a substrate temperature between 200 °C and 300 °C. Optical simulations were performed to compare the performance of MgF2 and MgO in the fabrication of near-UV narrow bandpass optical filters. While MgO-based optical filters result in a higher transmittance peak intensity, especially at 350 nm, the MgF2 optical filters are narrower, present lower values of FWHM, a mean value of 20 nm. This feature could be especially relevant for specific applications on fluorescent optical sensors. Finally, a Fabry-Perot based on a MgF2/TiO2 optical filter was deposited, using an e-beam technique for the MgF2 thin-films and RF-sputtering technique for the TiO2 thin-films. The MgF2/TiO2 optical filter peak transmittance is approximately 70% close to 400 nm, as expected. The results are discussed with focus on applications in fluorescent optical sensors for peaks at 350, 370, 380 and 400 nm, respectively.

- O objetivo deste trabalho é revisar sistematicamente a literatura sobre a integração interfuncional no contexto de PDP. Realizou-se uma revisão sistemática da literatura para identificar e analisar as principais vertentes de pesquisa. Obteve-se uma amostra final de 87 artigos que foram considerados nesta revisão. A análise de conteúdo dos artigos permitiu identificar e caracterizar três categorias principais: Vertentes de pesquisa; Fatores de integração e fases do PDP. Além disso, também foram analisados dados descritivos relacionados a principais revistas, país da pesquisa de campo e ano. Foram desenvolvidas três proposições e indicam a necessidade de integração interfuncional para eficiência NPD em três situações: alto fluxo de projetos dentro do PDP, alto envolvimento da empresa com inovação e alta complexidade do PDP. Por fim, uma agenda de pesquisa foi desenvolvida com base na articulação entre a teoria existente e as análises bibliométricas.

- PurposeThe purpose of this study is to analyze cross-functional integration processes and their respective impacts on resilience capabilities, with particular emphasis on collaboration, in an automotive supply chain.Design/methodology/approachA case study was conducted in an automotive supply chain through 18 in-depth interviews with managers from six different companies, namely, two suppliers, one focal manufacturer and three customers. The automotive industry is one of the most vital industries in the Brazilian economy and is still recovering from the 2015 financial crisis, making it an interesting case for this research.FindingsThe findings reveal several links between resilience and cross-functional integration literatures through the analysis of three basic categories, namely, disruptions (lack of product, interruption of production, delivery delay, organizational bankruptcy and sales loss); capabilities (redundancy, flexibility, adaptability, collaboration, visibility and agility); and integration factors (cross-functional meetings, adequate communication, longevity of relationships, cross-functional training, recognition of interdependence and the consideration given to informal groups).Practical implicationsThis research addresses several implications for practitioners. Managers should pay attention to the cross-functional teams, which may provide internal collaboration, and hence collaboration in the supply chain.Originality/valueThis paper suggests a new concept for the collaboration capability. According to the results, collaboration is the capability of dealing with formal and informal factors to integrate both the internal functions and supply chain members, which can provide visibility, agility and adaptability toward supply chain resilience.
