    Get PDF
    This study followed the systematic literature review approach to analyse how blockchain technology can improve supply chain management and to promote a future research agenda. The search was carried out at Web of Science Core Collection between September 2019 and February 2020 by using the keywords “blockchain” AND “supply chain” OR “blockchain” AND “logistics” in the title. In this review 127 studies were identified for screening and a final sample of 67 studies met the inclusion criteria and were analysed to answer the research questions. After examining the selected studies, our findings uncover a range of approaches showing how blockchain can enhance the supply chain management and point out which sectors are most likely to benefit from its implementation. This study contributes to the existing literature by systematising the most relevant information on blockchain implementation in supply chains. In addition, the findings of this study also provide managers and researchers with insights about the likely consequences of blockchain adoption in various sectors. Although there are already some literature reviews on blockchain technology in the supply chain management, this is one of the first studies that brings together the main issues focused on the consequences of blockchain adoption in the supply chain management.A gestão da cadeia de abastecimento está a passar por um processo de digitalização das suas operações justificada pela Quarta Revolução Industrial (Indústria 4.0) que prevê a adoção de novas tecnologias com o objetivo de reduzir custos operacionais, aumentar a eficiência da cadeia de abastecimento e agregar valor aos produtos e serviços. Ferramentas tecnológicas como a internet das coisas (IoT), identificação por radiofrequência (RFID) e Big Data, estão a ser utilizadas na melhoria dos controlos de produção, compra, procura, na tomadas de decisões dos gestores, entretanto, a recente tecnologia blockchain tem chamado atenção de pesquisadores e especialistas devido ao seu potencial transformador nos negócios e principalmente na gestão da cadeia de abastecimento. Por este motivo, este estudo propõe uma revisão sistemática de literatura com o objetivo de analisar como a tecnologia blockchain pode melhorar a gestão da cadeia de abastecimento e propor uma agenda de investigação para o futuro. A pesquisa foi realizada na base de dados Web of Science Core Collection entre setembro de 2019 e fevereiro de 2020 usando as palavras-chave "blockchain" E "supply chain" OU "blockchain" E "logistics" no título. O critério de seleção dos artigos considerou apenas estudos revistos por pares, anais de conferência e livros nos idiomas inglês, espanhol, francês e português. A seleção dos estudos ocorreu em duas etapas. Na primeira etapa, foram analisados títulos e resumos. Na segunda etapa, foi realizada a leitura integral dos estudos que não foram excluídos na primeira fase. Os critérios de exclusão foram: artigos de revisão de literatura, relatórios, estudos focados em informações técnicas, estudos que enfatizaram outras tecnologias (IoT, RFID), gestão financeira da cadeia de abastecimento e/ou estudos relacionados com bitcoins. Os artigos que preencheram um desses critérios foram excluídos com justificativa. Embora tenhamos excluído artigos de revisão de literatura, esses documentos ainda foram utilizados para identificar estudos-chave que não haviam sido capturados da base de dados Web of Science. Por fim, nesta revisão foram identificados 127 estudos para triagem e uma amostra final de 67 estudos atendeu aos critérios de inclusão e foram analisados para responder às perguntas da pesquisa. As perguntas a que a pesquisa teve por objetivo responder foram: quais os benefícios e riscos da tecnologia blockchain; quais os setores que já adotaram a tecnologia blockchain na gestão da cadeia de abastecimento e sua fase de implementação; quais as características das empresas que utilizam a tecnologia; quais são os fatores facilitadores e barreiras para a adoção da tecnologia blockchain nas empresas; qual a influência da tecnologia blockchain na garantia da sustentabilidade da cadeia de abastecimento dentro da estratégia organizacional e dos níveis operacionais; como avaliar o desempenho da tecnologia blockchain na gestão da cadeia de abastecimento. Os estudos selecionados apontam que a partir de 2017 houve um aumento expressivo de estudos relacionados ao uso da tecnologia blockchain na cadeia de abastecimento. Os Estados Unidos, China e Índia são os países com a maior percentagem de publicações sobre o tema e representam aproximadamente 44% do total. Os estudos foram publicados em jornais especializados em sistema de produção e processos, engenharia industrial, tecnologia, gestão, logística, cadeia de abastecimento e sustentabilidade. Quanto aos benefícios e riscos da adoção da tecnologia blockchain, os estudos indicam que a transparência dos dados, rastreabilidade e a redução dos custos operacionais são um dos maiores benefícios da adoção da tecnologia blockchain na cadeia de abastecimento, enquanto a escalabilidade e interoperabilidade foram identificados com os maiores riscos/limitações da implantação da tecnologia. No que tange aos fatores facilitadores da adoção da tecnologia blockchain, a gestão de topo apresenta-se como agente principal no incentivo à adoção do blockchain nas organizações, além disso, a perceção de utilização da tecnologia pelos funcionários também influencia o sucesso de implantação da tecnologia blockchain. Outras características que afetam a adoção da tecnologia são a infraestrutura das empresas, políticas governamentais e a cultura do país, entretanto esses fatores tendem a ter níveis diferentes de acordo com o país onde a empresa está instalada. No que diz respeito aos fatores que dificultam a implantação do blockchain nas organizações, são apontados a falta de conhecimento da tecnologia blockchain e dos seus potenciais benefícios, a existência de um número reduzido de aplicações do blockchain nas empresas, a coordenação e comprometimento dos parceiros de negócios na resolução de problemas e no tratamento de dados, fatores externos, como a legislação e incentivos governamentais. Após examinar os estudos selecionados, a nossa análise revela uma série de abordagens que mostram como a blockchain pode melhorar a gestão da cadeia de abastecimento e identifica os setores mais propensos a retirar benefícios de sua implementação. A indústria de alimentos e a indústria farmacêutica são apontados como os setores com maior vantagem na adoção do blockchain devido a criticidade dos seus produtos, a procura crescente por informações referente a proveniência dos bens e seu alto valor agregado. O perfil das organizações que adotaram a tecnologia blockchain são geralmente multinacionais de grande e médio porte, com capilaridade de parceiros de negócios, grande volume de produção e alto valor agregado aos seus bens. Quanto a sustentabilidade, a tecnologia blockchain pode influenciar, através da transparência e rastreabilidade dos produtos, na redução da produção de lixo e das emissões de carbono no meio ambiente, no controlo das leis e práticas laborais, evitando-se trabalho escravo e, relacionado com as questões económicas, redução dos custos com auditorias, controlo de pedidos de compra, produção e procura. Os indicadores de performance, de acordo com os estudos revistos, podem ser melhorados com a utilização da tecnologia blockchain, promovendo novas métricas sustentáveis baseadas na rastreabilidade e na transparência dos dados. Apesar da fase inicial da tecnologia blockchain, alguns estudos propõem indicadores que avaliam a eficiência da cadeia de abastecimento após a adoção do blockchain, como o tempo de processamento das transações, a utilização de recursos (água, energia elétrica) e níveis de emissão de carbono. Embora já existam algumas revisões de literatura sobre a tecnologia blockchain na gestão da cadeia de abastecimento, este é um dos primeiros estudos que reúne questões importantes focadas nas consequências da adoção do blockchain na gestão. Além disso, os resultados deste estudo fornecem implicações para a gestão e para a teoria sobre as prováveis consequências da adoção de blockchain em vários setores da economia

    Trialing project-based learning in a new EAP ESP course: A collaborative reflective practice of three college English teachers

    Get PDF
    Currently in many Chinese universities, the traditional College English course is facing the risk of being ‘marginalized’, replaced or even removed, and many hours previously allocated to the course are now being taken by EAP or ESP. At X University in northern China, a curriculum reform as such is taking place, as a result of which a new course has been created called ‘xue ke’ English. Despite the fact that ‘xue ke’ means subject literally, the course designer has made it clear that subject content is not the target, nor is the course the same as EAP or ESP. This curriculum initiative, while possibly having been justified with a rationale of some kind (e.g. to meet with changing social and/or academic needs of students and/or institutions), this is posing a great challenge for, as well as considerable pressure on, a number of College English teachers who have taught this single course for almost their entire teaching career. In such a context, three teachers formed a peer support group in Semester One this year, to work collaboratively co-tackling the challenge, and they chose Project-Based Learning (PBL) for the new course. This presentation will report on the implementation of this project, including the overall designing, operational procedure, and the teachers’ reflections. Based on discussion, pre-agreement was reached on the purpose and manner of collaboration as offering peer support for more effective teaching and learning and fulfilling and pleasant professional development. A WeChat group was set up as the chief platform for messaging, idea-sharing, and resource-exchanging. Physical meetings were supplementary, with sound agenda but flexible time, and venues. Mosoteach cloud class (lan mo yun ban ke) was established as a tool for virtual learning, employed both in and after class. Discussions were held at the beginning of the semester which determined only brief outlines for PBL implementation and allowed space for everyone to autonomously explore in their own way. Constant further discussions followed, which generated a great deal of opportunities for peer learning and lesson plan modifications. A reflective journal, in a greater or lesser detailed manner, was also kept by each teacher to record the journey of the collaboration. At the end of the semester, it was commonly recognized that, although challenges existed, the collaboration was overall a success and they were all willing to continue with it and endeavor to refine it to be a more professional and productive approach

    Open innovation development of private colleges in China

    Get PDF
    Since their large-scale emergence in the 1990s, private colleges in China have achieved significant development along with the transition of Chinese higher education from the elite stage to the universal stage. However, due to institutional deficiencies and resource constraints, private colleges cannot replicate the development model of public colleges and universities. Based on the needs for development and future competition, private colleges have to seek different development paths from public universities in order to break through resource constraints and improve their own development performance. We choose Tianfu College, a private college in China, as a research case, and adopt an inductive qualitative approach and an exploratory case study strategy based on grounded theory, with the development practice of knowledge production as the research subjects. The data is formed through semi-structured interviews, on-site observations, and the collection of secondary data. The research results show that 1) Private colleges in China can achieve good development performance in knowledge production through open innovation strategy. 2) Private colleges in China can adopt resource bricolage to break through resource constraints and achieve open innovation development performance in knowledge production. 3) Top management teams with high achievement needs and high ambiguity tolerance, entrepreneurial oriented organizational culture and organic organization help the private college in China achieve open innovation development performance in knowledge production. Our findings further expand the scope of open innovation research subjects, enrich the content of research on the development model of private colleges, and have positive practical implications for the development of private colleges in China.Desde a sua emergência em larga escala na década de 90 do século passado, as faculdades privadas na China alcançaram, no seu conjunto, um desenvolvimento significativo, que ocorreu juntamente com a transição do ensino superior chinês da fase elitista para a fase de popularização, e depois para a fase de universalização. Contudo, devido a deficiências institucionais e à limitação de recursos, as faculdades privadas não podem replicar o modelo de desenvolvimento das faculdades e universidades públicas. Com base numa necessidade de desenvolvimento realista e de concorrência futura, as faculdades privadas têm de procurar vias de desenvolvimento diferentes, de modo a ultrapassar as limitações de recursos e melhorar o seu próprio desempenho. Escolhemos Tianfu College, uma faculdade privada na China, como caso de investigação, e adotamos uma abordagem qualitativa indutiva e uma estratégia exploratória de estudo de caso baseada na Grounded Theory, sendo o tema de investigação a prática de desenvolvimento da produção de conhecimento. Os resultados da investigação mostram que 1) Um colégio privado na China pode alcançar um bom desempenho de desenvolvimento na produção de conhecimento através de uma estratégia de inovação aberta. 2) Um colégio privado na China pode adotar uma abordagem da bricolagem de recursos para quebrar as restrições de recursos e obter um desempenho de desenvolvimento de inovação aberta na produção de conhecimento. 3) Uma equipa de gestão de topo com elevada necessidade de concretização e elevada tolerância à ambiguidade, uma cultura organizacional orientada para o empreendedorismo e uma estrutura orgânica, são condições para se alcançar um elevado desempenho na produção de conhecimento através de inovação aberta. Os resultados permitem alargar o âmbito da investigação em inovação aberta, enriquecem o conteúdo da investigação sobre modelos de desenvolvimento das faculdades privadas, e têm implicações práticas positivas para o desenvolvimento das faculdades privadas na China

    GIS-based earthquake disaster management system for seismic risk assessment: a case study of Sabah and Pahang, Malaysia

    Get PDF
    Earthquake disaster management in Malaysia is still at the initial stages and faces multiple challenges. There is a dearth research on, and tools for, seismic risk assessment when estimating the impact of earthquakes for specific areas. Furthermore, the absence of a central authority to integrate earthquake disaster management and lack of coordination among organizations has caused crucial data related to the earthquakes to be managed separately and in different formats. Therefore, this research aim is to develop a GIS-based earthquake management system for seismic risk assessment that involves the development and verification of the seismic vulnerability index for Malaysia; the development of a GIS-based earthquake management system database for risk management planning; and an evaluation of the proposed seismic vulnerability and risk assessment modeling system. The methodology specifically relies on the development of a set of vulnerability index indicators using multivariate data analysis to identify the local characteristics that contribute to the vulnerability and risk of inhabitants at the district scale; and the development of GIS-based system with a modeling application to generate and map the spatial distributions of seismic vulnerability and risk. The study revealed the highest levels of seismic risk were concentrated in the centre-west of the Pahang region, namely the Bentong district, whereas in Sabah the riskiest areas encompassed the district of Lahad Datu, Sandakan, Semporna, Tawau and Kunak. Evaluation of risk assessment modeling systems through the integration of verification and validation processes demonstrates a reliable and robust modeling system to perform vulnerability and risk assessment. Finally, the contribution of this study offers an alternative methodology for developed countries, which often face the lack of comprehensive and readily available data for vulnerability assessment. The weighting scheme method has been extensively used in several disciplines, particularly the field of climate change and has yet to be applied for calculating weights for seismic vulnerability and risk indicators

    Organizational innovation factors, capabilities and organizational performance in Iranian automotive industry

    Get PDF
    Understanding the relationship between innovation and performance of firms for both large and small organisations is relevant for researchers and policy-makers. Many firms and organisations have begun to recognise that innovation proficiency is the key to building a sustainable competitive advantage for their products or services in a progressively crowded marketplace. Even though defining innovation capability through its antecedents is considered as a unique methodology, a theoretical and comprehensive study about the effects of internal and external innovation drivers on organisational performance is still scarce. This study addresses the deficiency of empirical studies by developing a comprehensive model to examine the effects of external innovation drivers and internal innovation drivers namely organisational culture and intellectual capital on organisational performance directly and through innovation capability. A quantitative methodology is used to investigate the relationship paths. Data were collected from 275 companies in the automotive sector in Iran by using a cross-sectional survey method. Partial Least Squares Structural Equation Modelling (PLS-SEM) was used in the hypotheses testing. The results indicate that internal and external organisational innovation has a positive and significant relationship with organisational performance directly and through organisational innovation. Fundamentally, the results of this study can assist organisations and academic bodies to expand their knowledge on the role of innovation drivers and the capability of organisational performance in automotive industry
