Uma metodologia para a implementação de comércio e negócio electrónico em pequenas e médias empresas

Tese de doutoramento em Tecnologias e Sistemas de InformaçãoA tecnologia da World Wide Web, que se suporta na Internet, está a transformar todas as actividades de negócio em actividades baseadas em informação, assistindo-se a uma mudança radical dos modelos teóricos e de organização tradicionais. As pequenas e médias empresas constituem o tipo de empresa que mais vantagens podem retirar da utilização da Internet para o comércio electrónico e o negócio electrónico. No entanto, os resultados da adopção de comércio e negócio electrónico, a este nível, contrariam a expectativa. Na procura de razões para o facto, constatámos que as metodologias existentes possuem insuficiências para ajudar as pequenas e médias empresas a definir e implementar uma tal estratégia. Concluiu-se, assim, sobre a necessidade da definição de uma metodologia que recolha essas insuficiências e proponha alternativas que permitam colmatar as mesmas. Atendendo à relevância do assunto, tornou-se no objectivo deste trabalho de investigação, a procura de uma metodologia que permita endereçar todas as perspectivas relacionadas com a adopção e implementação de mecanismos de comércio electrónico e negócio electrónico na pequenas e médias empresas. Tendo por referência esta finalidade, foi desenvolvida uma metodologia específica para a implementação de mecanismos de comércio electrónico e negócio electrónico na pequena e média empresa, tendo uma base teórica sólida e uma validação prática real.The World Wide Web technology, which is supported on Internet, is transforming all business activities into information-based activities, where one can see a radical change of the traditional theoretical models and organization. Small and medium enterprises are the type of enterprises that can take more advantages with the use of Internet for electronic commerce and electronic business. Nevertheless, the results coming from the EC and EB adoption are opposite to expectations. Searching reasons for this fact, we found that existing methodologies are insufficient to help small and medium enterprises to define and implement such a strategy. Thus, we concluded about the need of a methodology definition able to overcome those gaps and propose alternatives. Taking into account the meaning of this topic the aim of this research work is to seek for a methodology able to lead all the perspectives related with adoption and implementation of electronic commerce and electronic business in the small and medium enterprises. Having this goal in mind, a specific methodology was developed to implement the electronic commerce and electronic business mechanisms in the small and medium enterprises having a solid theoretical ground and a practical real validation

Artificial intelligence applied to potential assessment and talent identification in an organisational context

França, T. J. F., São Mamede, J. H. P., Barroso, J. M. P., & Santos, V. M. P. D. D. (2023). Artificial intelligence applied to potential assessment and talent identification in an organisational context. Heliyon, 9(4), 1-25. [e14694]. https://doi.org/10.1016/j.heliyon.2023.e14694Our study provides valuable insights into the relationship between artificial intelligence (AI) and Human Resource Management (HRM). We have minimised bias and ensured reliable findings by employing a systematic literature review and the PRISMA statement. Our comprehensive synthesis of the studies included in this research, along with a bibliometric analysis of articles, journals, indexes, authors' affiliations, citations, keyword co-occurrences, and co-authorship analysis, has produced robust results. The discussion of our findings focuses on critical areas of interest, such as AI and Talent, AI Bias, Ethics and Law, and their impact on Human Resource (HR) management. Our research highlights the recognition by organisations of the importance of talent management in achieving a competitive advantage as higher-level skills become increasingly necessary. Although some HR managers have adopted AI technology for talent acquisition, our study reveals that there is still room for improvement. Our study is in line with previous research that acknowledges the potential for AI to revolutionise HR management and the future of work. Our findings emphasise the need for HR managers to be proactive in embracing technology and bridging the technological, human, societal, and governmental gaps. Our study contributes to the growing body of AI and HR management knowledge, providing essential insights and recommendations for future research. The importance of our study lies in its focus on the role of HR in promoting the benefits of AI-based applications, thereby creating a larger body of knowledge from an organisational perspective.publishersversionpublishe

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
