Desenvolvimento de recursos de design em pequenas empresas da indústria automóvel : uma abordagem metodológica

ABSTRACT: This paper reflects part of a broader investigation on the development of methodologies to identify, value and manage design capabilities in order to create a sustainable competitive advantage. With the automotive industry and smaller supplier Portuguese companies as background, this paper explores the resource-based view theory (RBV) and the dynamic capabilities theory as a theoretical construct for a further development of research tools. In the automotive industry, OEM (Original Equipment Manufacturers) continue to control the overall design of the vehicle, as part of the ability to manage the offer portfolio and brand communication. However, the industry have been moving towards an increasing participation of smaller suppliers in product development processes, pushed towards capabilities’ development as a requirement to continue competitive in the OEM’s suppliers network. The role of design and design management capabilities have been explored as strategic resources or core competencies. However, Design is not typically found in smaller supplier firms as resource (as opposed to Design studios in larger companies) but found as a process in resourcecapability combinations, establishing the need for a new research approach. Therefore, the RBV is a tool to value the design process as a sustained competitive advantage. The RBV conceptualizes a framework to determine or identify the strategic resources available or needed within a company. At these lenses, the basis for a sustainable competitive advantage lies in the application of the bundle of valuable resources identified and at the firm's disposal and the combinations with its capabilitiesEste artigo reflete parte de uma investigação mais ampla sobre o desenvolvimento de metodologias para identificar, valorizar e gerir os recursos de design, com o objetivo de criar uma vantagem competitiva sustentável. Com a indústria automóvel e as pequenas empresas portuguesas fornecedoras como pano de fundo, este artigo explora a teoria da Resource Based View (RBV) e a teoria das Dynamic Capabili_es (DCT) como um construto teórico para o desenvolvimento de ferramentas de investigação. Na indústria automóvel, os OEM (fabricantes de equipamentos originais) continuam a controlar o design geral do veículo, como parte da capacidade de gestão do seu portfólio assim como a comunicação de marca. No entanto, o setor tem seguido um caminho para uma participação crescente de fornecedores menores nos processos de desenvolvimento de produto, impulsionados para o desenvolvimento de capacidades como requisito de competitividade na rede de fornecedores dos OEM. O papel dos recursos do design e da gestão do design foram já explorados como recurso estratégicos ou competências fundamentais. No entanto, o Design não é normalmente encontrado em empresas de menor dimensão como recurso (em oposição aos estúdios de Design em empresas maiores), mas sim como um processo de combinações de diferentes capacidades e recursos, estabelecendo a necessidade de uma nova abordagem de pesquisa. Portanto, a RBV é uma ferramenta que visa a valorização do processo de design como uma vantagem competitiva sustentada. A RBV concetualiza uma estrutura para determinar ou identificar os recursos estratégicos disponíveis ou necessários dentro de uma empresa. Deste ponto de vista, a base para uma vantagem competitiva sustentável está na aplicação do conjunto de recursos valiosos identificados e à disposição da empresa em forma de combinações das suas diferentes capacidades e recursos.info:eu-repo/semantics/publishedVersio

Advantages of using user experience design concepts in the creation of e-learning courses

Trabalho de Projeto de Mestrado, Educação (Área de Especialidade em Educação e Tecnologias Digitais), Universidade de Lisboa, Instituto de Educação, 2021This work focuses on the advantages of the application of User Experience Design concepts in the creation of e-learning courses showing how Instructional Designers can benefit from its application to improve the learning experience by following some of the rules and conventions for good website design. It starts by covering the definition of the term User Experience Design providing background information about the authors who have popularised the term, explaining its association with Usability, going through the advantages of applying it to e-learning courses, and ending with a practical application of the concepts. The practical component of the work lays on the assessment of a course to identify the elements that can be improved following the User Experience Design concepts found in the literature review and the application of those same concepts to a makeover of the original course that then allows the comparison of the two versions. Several elements in the original version were identified as needing improvement: blank space, lack of visual elements, navigation, clickable items, placement of the logo, responsiveness to different screens, and aesthetics. The course makeover was built using the authoring software Articulate Storyline that allowed the development of a version that promotes a better experience to the learner by reallocating some items, enhancing fonts and buttons, making it adjustable to different screen types, and modernising its layout. This work tries to prove that Instructional Designers can certainly benefit from applying User Experience Design concepts to help them identify some issues that otherwise could not be easily detected by simply following Instructional Design models.Este trabalho debruça-se sobre as vantagens da aplicação dos conceitos de User Experience Design na criação de cursos e-learning demonstrando como os Designers Instrucionais podem beneficiar de sua aplicação para melhorar a experiência de aprendizagem, seguindo algumas das regras e convenções base para um bom desenho de websites. Começa por abordar a definição do termo User Experience Design fornecendo informação histórica sobre os autores que o popularizaram, explanando a sua associação ao termo Usabilidade, passando pelas vantagens da sua aplicação em cursos de e-learning e terminando com demonstração da aplicação prática dos conceitos. A componente prática do trabalho consistiu na avaliação de um curso existente online para identificar os diferentes elementos que poderiam ser melhorados seguindo os conceitos de User Experience Design encontrados na revisão de literatura e aplicando desses mesmos conceitos numa nova versão do curso, permitindo-se adicionalmente a comparação entre ambas as versões. Na versão original, identificaram-se os seguintes elementos com necessidade de melhoria do ponto de vista de experiência do utilizador: espaço em branco, falta de elementos visuais, navegação, itens clicáveis, posicionamento do logotipo, responsividade do conteúdo a diferentes ecrãs e estética geral. A reformulação do curso foi desenvolvida com o software de autoria Articulate Storyline que possibilitou o desenvolvimento de uma versão que promove uma melhor experiência de aprendizagem através da recolocação de alguns itens, aprimoramento da tipografia e botões, maior adaptabilidade do conteúdo a diferentes tamanhos de ecrã e modernização do layout. Este trabalho mostra como os designers instrucionais podem beneficiar da aplicação de conceitos associados ao User Experience Design, demonstrando em que medidas estes o podem ajudar a identificar alguns problemas que, de outra forma, não seriam facilmente detetados apenas seguindo modelos associados ao Design Instrucional

A new genus of railroad-worm beetles from the Atlantic Rainforest from Brazil (Coleoptera: Phengodidae, Mastinocerinae)

Here we describe a new genus, Cleidella gen. nov., and two new species, C. picea sp. nov. and C. silveirai sp. nov., all from Rio de Janeiro State, Brazil. The new genus is characterized by the interantennal distance subequal to scape length, antenna with 11 antennomeres, IV to X with two long symmetrical branches; mandibles long, projected and not crossed, pointed forward obliquely from head; maxillary palpi 4‑segmented, last segment digitiform; labial palpi 2‑segmented; posterior tentorial pit consisting of a single small fossa; elytron surpassing from the fourth to fifth abdominal segment, 3.3‑3.9× longer than wide; first tarsomere of protarsus with a ventral comb as long as the tarsomere length; wing with radial cell closed and transverse, vein r4 interrupted; aedeagus with paramere symmetrical, apex unevenly round, toothed inward, with short and scarce bristles. We provide a key to Mastinocerinae genera with 11 antennomeres, as well as illustrations for the diagnostic features for this new genus and a key to its species

Novel enzymes for the agro-food industries

Dissertação de mestrado em Bioquímica Aplicada (especialização em Biomedicina)Enzymes are biological catalysts that accelerate the rate of chemical reactions in cells and are commonly used in a range of industries. They can improve the efficiency, cost-effectiveness and environmental impact of many processes and enhance the characteristics and quality of products. New enzymes with novel backbone sequences and novel functions and characteristics are constantly called for. In the present project, 116 yeasts from mainly acidic pH biowastes, 11 aquatic filamentous fungi from cold environments in Portugal and Iceland, 3 bacterial isolates and 3 metagenomic clones from Irish soil samples were screened for the production of glycoside hydrolase enzymes of industrial interest, namely xylanases, cellulases, pectinases and chitinases. Methods were investigated and developed for a simplified screening of the various isolates at 16 ºC, pHs 4, 7 and 9, with, in particular, the development of a novel xylanase substrate. The substrate was shown to be suitable for measurement of xylanase activity with the commonly used DNS assay but further tests with other xylanases are recommended to confirm this. Furthermore, the substrate was successfully coupled with remazol brilliant blue (RBB) dye, obtaining a chromogenic substrate and enabling a highly sensitive and efficient plate based screening of xylanases. Screening of the CBMA culture collection isolates allowed for identification of a large number of glycoside hydrolase positive isolates, with 31 isolates showing desired activities exclusively at acidic pH. These enzymes may be of interest for use in various applications and, in particular, in food and beverages applications. In addition, 5 isolates were found to display all 4 activities screened for at pH 4, and these isolates may have potential for use in biomass treatment applications. A cellulase positive metagenomic clone with metagenomic DNA from Irish soil was selected for further analysis. The gene for this cellulase was successfully amplified and digested with restriction enzymes but attempts at ligation in an expression vector and transformation to an E. coli expression host proved unsuccessful within the time scope of the project. Further studies should be focused on overexpressing and characterising this novel enzyme.As enzimas são catalisadores biológicos que aceleram reações químicas, sendo usadas diariamente numa ampla gama de indústrias, promovendo a melhoria da eficiência de processos, da relação custo eficiência, assim como o impacto ambiental, para além de melhorar as características e a qualidade do produto. Há uma constante demanda por novas enzimas, de sequências, funções e características inovadoras. Neste projeto, 116 leveduras, maioritariamente provenientes de bio-resíduos acídicos, 11 fungos filamentosos de ambientes frios em Portugal e Islândia, 3 isolados bacteriais e 3 clones metagenómicos de amostras de solo Irlandês foram usados num rastreio por enzimas glicosil hidrolases de interesse industrial, nomeadamente, xilanases, celulases, pectinases e quitinases. Métodos para um rastreio simplificado dos vários isolados a 16 ºC, a pH 4, 7 e 9, foram investigados e desenvolvidos, tendo-se em particular, desenvolvido um novo substrato de xilanase. Este substrato demonstrou, através do ensaio DNS, ser apropriado para a medição de atividade xilanolítica, mas testes com outras xilanases são necessários para obter confirmação. Adicionalmente, este substrato foi ligado com sucesso ao corante remazol brilliant blue (RBB), obtendo-se um substrato cromogénico, possibilitando um rastreio de xilanases, em placas, altamente sensível e eficiente. O rastreio dos isolados da coleção de culturas do CBMA permitiu a identificação de um grande número de isolados positivos para a presença de glicosil hidrolases, em que 31 demonstraram atividade exclusivamente a pH acídico. Estas enzimas podem ser de interesse para uso em várias aplicações, particularmente na indústria alimentar. Adicionalmente, 5 isolados mostraram ter atividade para todas as enzimas rastreadas a pH 4, podendo ter um potencial uso no tratamento de biomassa. Um clone metagenómico, com ADN metagenómico de solo Irlandês, positivo para atividade celulolítica, foi selecionado para análise adicional. O gene desta celulase foi amplificado com sucesso por PCR e digerido com enzimas de restrição apropriadas, mas tentativas de ligação num vetor de expressão e transformação para hospedeiro de expressão E.coli não foram bem sucedidas dentro do tempo limite do projeto. Estudos futuros deverão concentrar-se em expressar e caracterizar esta nova enzima

IgA dominant glomerulonephritis associated to staphylococcus infection: a peculiar case report

IgA dominant glomerulonephritis associated to Staphylococcus infection is a rare clinical entity that has been described mainly in case reports. Biopsy features can resemble other disease entities mainly IgA nephropathy and Henoch‑Schönlein purpura nephritis. Treatment of IgA dominant glomerulonephritis associated to staphylococcal infection is based on antibiotics for the underlying infection, controlling hypertension and edema and may resort to concomitant use of steroids in selected cases. Prognosis markers such as hypertension, diabetes and interstitial fibrosis may influence treatment as they are associated with poor renal outcomes. We report a case of a 63‑year‑old man with known hypertension, pre‑diabetes and recent history of methicillin‐sensitive staphylococcus aureus bacteremia associated to prostatitis, who presented with a one‑month history of edema, arthralgia and foamy urine. Over this period he progressed to anasarca and nephrotic range proteinuria with concomitant rise in creatinine levels being documented. The renal biopsy showed segmental endocapillary proliferation and IgA segmental dominant staining associated to C3 and lambda in minor distribution. On completion of two months of steroid therapy the patient partially recovered his renal function and proteinuria. After nine months of tapering steroids, he presented with acute inflammatory arthritis supporting an inflammatory background disease. To our knowledge this case describes an unusual entity such as IgA dominant glomerulonephritis associated to staphylococcal infection co‑presenting with an associated reactive arthritis.info:eu-repo/semantics/publishedVersio

Analysis of processing methods for combustion pressure measurement in a diesel engine

This paper analyzes combustion chamber pressure data processing methods related to the number of cycles averaged, top dead center referencing and pressure referencing (pegging). A total of 1000 consecutive engine cycles were measured in a four-cylinder diesel engine. The number of cycles that minimizes the influence of cycle-to-cycle oscillations depends on engine operating conditions and the parameters under analysis. The top dead center (TDC) referencing, using the motored curve, revealed that the thermodynamic loss shifts the peak pressure − 0.4 °CA from TDC. Four pegging methods were compared—least-squares, fixed-point, three-point and two-point—introducing as main novelty the fact they have not been previously investigated on the same baseline conditions. The least-squares based method showed the lowest sensitivity to random noise, but with longer processing time, and the fixed-point method presented higher dispersion in the heat release analysis. The three-point referencing method considers a variable polytropic coefficient, but suffers from noise sensitivity, and the two-point referencing method presented close values and higher dispersion in comparison with the least-squares method. The choice of which method to use depends on the type of analysis, signal quality and processing time available

A EDUCAÇÃO FÍSICA NA EDUCAÇÃO INFANTIL (0 A 3 ANOS): O ESTADO DA ARTE A PARTIR DE PUBLICAÇÕES DA ANPED

Em algumas instituições de educação infantil o que está em conflito é, por um lado, a visão assistencialista e, por outro, a visão voltada para a capacidade de aprendizagem de cunho escolar. Dentro desta complexidade a Educação Física, aqui entendida como cultural do movimento é deixada de lado. Sendo assim, a presente pesquisa teve como objetivo conhecer a produção científica veiculada por um evento nacional acerca da Educação Física nos anos iniciais da educação infantil. Para tanto utilizamos como metodologia de pesquisa aquela denominada de estado da arte ou estado do conhecimento. Optamos como base a ser pesquisada a Associação Nacional de Pós-Graduação e Pesquisa em Educação ANPED. Contudo, notamos que há escassez de pesquisas sobre tema aqui abordado, pois não possui reflexo na base de dados pesquisado. Concluímos que se fazem necessárias pesquisas sobre o tema para que as propostas pedagógicas avancem as de cunho assistencialista e escolarizantes

Implementing Privacy-Preserving and Collaborative Industrial Artificial Intelligence

Publisher Copyright: © 2013 IEEE.Despite the growing connectivity and availability of sensor data boosted by the Industry 4.0 paradigm, data scarcity remains one of the biggest challenges for the widespread adoption of industrial AI, particularly regarding failure or defect data required for automated quality inspection solutions. Data sharing among different stakeholders is difficult due to data privacy, ownership, and cybersecurity concerns. Traditional centralized Machine Learning is already an essential part of several sectors, including smart manufacturing; however, it may lead to several issues regarding security and performance over time. In response to these problems, federated learning can be seen as a potential catalyst and enabler for the adoption of collaborative industrial artificial intelligence. It is an innovative and decentralized approach to machine learning, focused on collaboration and data privacy, shifting the information flow from the data to the models. Although considerable research efforts have been put forth towards this topic, there are still many unresolved issues concerning the application of federated learning approaches in smart manufacturing scenarios, including the lack of a common holistic reference framework and implementation. In this light, the present work aims to provide the foundation for a common framework for collaborative Industrial AI in smart manufacturing, addressing not only the collaboration aspect but also the main challenges of data privacy, ownership, and security. Additionally, we present and make publicly available a curated dataset focused on a manufacturing quality inspection scenario to further promote research on this topic.publishersversionpublishe

Teaching activity with ICT: perspectives on a regular high school in Bahia

The teachers of today are inserted in a technological era that provokes them to review their methodological practices. Information and communication technologies (ICTs) is an instrument, although it is not a recent issue. But it is able to offer learners new possibilities for learning. The teacher is based on mastering this tool. The teaching units together with the public managers must subsidize with adequate infrastructure in both hardware, software, internet, applications as well as continuous training. However, many teachers, even though they have received adequate knowledge to deal with the interactive media in the classroom and thus convey new meaning to teach, tend to remain with the old models of teaching and learning. The students are against it. The aim was to understand the apathy, incompleteness or frustration regarding the use of technological media in the classroom of a public high school in the city of Senhor do Bonfim-BA. The research was conducted, preferably, on the night shift, in June, through a questionnaire applied to 18 teachers (100% of the sample). In order to answer the problem: Is teaching time a factor that contributes to the non-use of ICTs in school? The results showed that most of the faculty has more than 20 years of teaching. Another important factor was the infrastructure still to be desired, and both the handsets and the network connectivity are not satisfactory. The data show that the teaching time is a negative factor, considering that they are not teachers who were born of the technological culture
