ABSTRACT The characterisation and evaluation of accessions are important steps in both the management of a germplasm collection and in a plant genetic improvement program. Carrying out characterisation and evaluation, whether morphological or molecular, requires observing the overall features of plants in the field, or collecting leaves for DNA extraction, which is time consuming and costly; whereas DNA extracted directly from the seeds allows access to the genome without the need for planting the seeds, which speeds up the selection of genotypes of interest and information on genetic variability. The aim was to develop a non-destructive method for extracting DNA from cashew seeds. The seeds were mechanically perforated using a mini-grinder, and a sample of the endosperm was removed. Various protocols and commercial kits for DNA extraction were tested, as well as materials to seal the opening made in the seed. It is possible to extract cashew tree DNA from the endosperm, preferably using commercial kits with cementitious adhesive as the sealing material, offering a germination percentage of 60% of the perforated seeds. program molecular field costly variability nondestructive non destructive minigrinder, minigrinder mini grinder, grinder mini-grinder removed tested seed material 60 6

RESUMO: A estrutura do sistema radicular do cafeeiro Conilon tem sido aprimorada ao longo dos anos por meio de propagação e estudos genéticos e agronômicos em resposta às demandas por melhorias no desenvolvimento vegetal, na produção e na sobrevivência da espécie. Entende-se que a pesquisa científica desempenha um papel importante na geração de tecnologias e também na segurança das aplicações. Porém, há necessidade de refinar o código gerado para descobrir descobertas e tendências sobre o assunto. Nesse sentido, o presente estudo tem como objetivo realizar uma revisão bibliométrica e análise na base de dados Web of Science (WOS) sobre as principais contribuições de estudos, pesquisadores, organizações e países relevantes nas pesquisas acadêmicas sobre o enraizamento de Coffea canephora. Dados da base de dados WOS publicados entre 1982 e 2021 e sistematizados no software VOSviewer, mostraram um conjunto de 92 artigos, em que a maioria teve origem no Brasil e na França, tendo como principais grupos a Empresa Brasileira de Pesquisa Agropecuária, a Universidade Federal de Viçosa e o CIRAD. O estudo está dividido em quatro áreas: diversidade genética, propagação assexuada, nematologia, tolerância ao estresse hídrico e micropropagação, porém, destaca-se que no contexto das mudanças climáticas e seu impacto na produção e longevidade da cafeicultura brasileira, podemos ver o surgimento de pesquisas focadas no sistema radicular, integrando-o em linhas que exploram e integram temas como risco climático, gestão hídrica, tolerância à seca e irrigação por gotejamento, incluindo reflexões sobre o desempenho da agronomia cafeeira.

ABSTRACT Introduction/framework/objectives Over the last few years, most countries have developed standards relating to reducing the number of places where smoking continues to be possible, particularly in the workplace. This review was intended to summarize the most recent publications on the topic. Methodology This is a Bibliographic Review, initiated through a search carried out in April 2023 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content Passive Smoking is defined as "second-hand" smoke that encompasses a complex mixture of pollutants, remaining in the dust on local surfaces where it was smoked, consisting of the original tobacco products and the components originating in the direct consumer's breath, eventually reacting to other agents gifts. These can remain on inert surfaces, sometimes for months and transmission can occur by simple touch. Some researchers estimate that there are around 4000 chemical agents in this context, of which 250 are toxic and 50 are even carcinogenic. Tobacco is one of the preventable causes of death worldwide and a modifiable risk factor, through mechanisms that include DNA damage, inflammation and oxidative stress. It involves health costs and reduced labor productivity, due to associated pathologies, namely cardiovascular, respiratory, oncological, obstetric and infectious diseases. Discussion and Conclusions Over the last few decades, there has been a global decrease in passive smoke, due to the introduction of increasingly restrictive standards in relation to places where smoking is still permitted, in society in general and, obviously, in the workplace as well. The selected articles did not highlight the following detail much but, by creating areas where smoking is permitted in the company, these should minimize the exposure of all workers, smokers and, above all, non-smokers. It would be desirable for countries/institutions where standards are less restrictive and/or enforced to change, so that all workers have a safe working environment. Furthermore, it would be interesting to understand what opinion Portuguese workers have regarding this topic, how standards are complied with in their workplaces and what are the most effective techniques to achieve greater success in this context.

RESUMO Introdução/enquadramento/objetivos Ao longo dos últimos anos a generalidade dos países foi desenvolvendo normas relativas à diminuição dos locais onde continua a ser possível fumar, nomeadamente em contexto laboral. Pretendeu-se com esta revisão resumir o que de mais recente se publicou sobre o tema. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo O Tabagismo Passivo é definido como fumo de "segunda mão" que engloba uma mistura complexa de poluentes, permanecendo na poeira das superfícies locais onde se fumou, constituída pelos produtos tabágicos originais e os componentes originários pela respiração do consumidor direto, eventualmente reagindo a outros agentes presentes. Estes podem permanecer nas superfícies inertes, por vezes, por meses e a transmissão pode ocorrer pelo simples toque. Alguns investigadores estimam que existam neste contexto cerca de 4000 agentes químicos, dos quais 250 são tóxicos e 50 são inclusivamente carcinogénicos. O tabaco é uma das causas preveníveis de morte mundialmente e fator de risco modificável, por mecanismos que abarcam o dano de DNA, inflamação e stress oxidativo. Ele implica custos de saúde e de diminuição da produtividade laboral, em função das patologias associadas, nomeadamente cardiovascular, respiratória, oncológica, obstétrica e infeciosa. Discussão e Conclusões Ao longo das últimas décadas verificou-se, globalmente, uma diminuição ao Tabagismo Passivo, devido à introdução de normas cada vez mais restritivas em relação aos locais onde ainda é permitido fumar, na sociedade em geral e, obviamente, em contexto de trabalho também. Os artigos selecionados não realçaram muito o seguinte detalhe mas, criando-se áreas onde é permitido fumar na empresa, estas devem minimizar a exposição de todos os trabalhadores, tabagistas e, sobretudo, não fumadores. Seria desejável que os países/instituições onde as normas são menos restritivas e/ou cumpridas, tal se alterasse, de forma a todos os trabalhadores terem um ambiente laboral seguro. Para além disso, seria interessante perceber qual a opinião que os trabalhadores portugueses têm em relação a este tema, de que forma as normas são cumpridas nos seus locais de trabalho e quais as técnicas mais eficazes para obter mais sucesso neste contexto.

Abstract In recent years, digital transformation processes have been gaining relevance. However, not all companies are achieving the same degree of transformation. The presence of barriers and enablers plays a significant role in this process. Furthermore, the extent of digital transformation also impacts how human resources (HR) policies are deployed and influences the effect they have on employees. This work aims to understand how the digital transformation process is occurring from a qualitative approach. Specifically, this study analyzes the main drivers and barriers of firms' digitalization, as well as its effects on companies, people, and human resource practices. Eight semi-structured interviews were conducted with key informants in three companies to gain an in-depth insight into the research problem. ATLAS.ti was used for data analysis and coding. Results show the presence of barriers and facilitators documented in existing literature. However, our results reveal that the business size and the firm's main activity are important variables that affect the extent of digital transformation. The study also reveals the benefits of digitalization in terms of efficiency and human resource autonomy (flexibility, work-life balance). Likewise, the findings unveil the negative consequences of digitalization with risks such as depersonalization and isolation that undermine talent retention.

Resumen En los últimos años, el proceso de transformación digital ha ido ganando importancia. Sin embargo, no todas las empresas adquieren el mismo nivel de transformación. La presencia de barreras y facilitadores desempeña un papel importante en este proceso. Además, el alcance de la transformación digital también influye en cómo se ejecutan las políticas de recursos humanos (RH) y su impacto en los empleados. Este trabajo pretende comprender cómo se está produciendo el proceso de transformación digital desde un enfoque cualitativo. En concreto, en este estudio se analizan los principales impulsores y barreras de la digitalización en las empresas, así como sus efectos sobre la empresa, las personas y, sobre las prácticas de recursos humanos. Se realizaron ocho entrevistas semiestructuradas a informantes clave de tres empresas para conocer en profundidad el problema de investigación. Se utilizó ATLAS.ti para el análisis y la codificación de los datos. Los resultados muestran la existencia de barreras y facilitadores, tal y como ha identificado la literatura existente, sin embargo, nuestros resultados muestran que el tamaño de la empresa y el sector al que pertenece son variables importantes que afectan al nivel de transformación digital. El estudio también revela los beneficios de la digitalización en términos de eficiencia y sobre la autonomía de los recursos humanos (flexibilidad, conciliación). Asimismo, los resultados muestran también los efectos negativos de la digitalización como los riesgos como la despersonalización y el aislamiento que socavan la retención del talento.

Abstract Open innovation proposes information exchanges between the company and external stakeholders to improve the results of innovation processes. In this work we adopt the open innovation approach to enhance a company’s innovation performance by implementing co-creation practices with customers. To do this, we rely on design thinking, a framework focusing on the relationship with end users, and adopt action research as a research methodology. The research is carried out in a service SME, characterised by being knowledge-intensive and offering innovative and customised services with high value added. We identify several co-creation practices and examine their degree of adoption by the company and prioritise those that should be implemented. For academics, this work contributes to increase the stock of knowledge on co-creation in the context of SMEs. The study offers valuable insights to practitioners into how an innovation framework that incorporates co-creation practices helps to improve the firm's innovation results, while presenting a methodology that facilitates collaboration with researchers on innovation projects.

RESUMEN La industria del tabaco, como cualquier otra, es participe del producto interno bruto y la generación de empleo en cualquier país. No obstante, los gobiernos han establecido mecanismos fiscales para erradicar su consumo, debido a las enfermedades que ocasiona como cáncer pulmonar, bronquitis crónica; lo que puede llevar a la muerte. En este sentido, se propone una aplicación de un modelo de externalidades para la producción de tabaco en México. Se obtuvieron dos mecanismos para la erradicación del tabaco, uno de ellos implica que las empresas disminuyan salarios de los trabajadores por el aumento de impuestos; el segundo, aumentar precios del tabaco permitiendo que las empresas equilibren su presupuesto. Ambos mecanismos implican un desajuste presupuestal para los ciudadanos, pero el segundo es una solución socialmente optima, pues solo se ven afectados los consumidores de tabaco y no así los que dependen del empleo y salario de la empresa.

ABSTRACT The tobacco industry, like any other, is a participant in the gross domestic product and the generation of employment in any country. However, governments have established fiscal mechanisms to eradicate its consumption, due to the diseases it causes such as lung cancer, chronic bronchitis; what can lead to death. In this sense, an application of an externalities model for tobacco production in Mexico is proposed. Two mechanisms were obtained for the eradication of tobacco; one of them implies that companies reduce workers' wages due to the increase in taxes. A second is to increase tobacco prices allowing companies to balance their budget. Both mechanisms imply a budget imbalance for citizens, but the second is a socially optimal solution, since only tobacco users are affected and not those who depend on the company's employment and salary.
