Are your students safe to learn? The role of lecturer’s authentic leadership in the creation of psychologically safe environments and their impact on academic performance:The role of teacher's authentic leadership on the creation of psychologically safe environments and their impact on academic performance

As the role of students and lecturers in higher education changes, several questions emerge about the role of each of them on students? academic performance. This includes questions regarding the impact of the relationships between students, lecturer?s characteristics and the social environment on students? performance. To address these questions, this article reports a study of the impact of lecturer authentic leadership, psychological safety and network density on academic performance. It explores the relationship between network density, psychological safety and lecturer authentic leadership. A questionnaire was distributed to undergraduate students. A positive impact of lecturer authentic leadership and psychological safety on academic performance was found. Students from high-density groups tended to show better academic performance, higher psychological safety and tended to see their lecturers as being more authentic. A reflection on the role of the lecturer in higher education settings is presented. It also presents some recommendations on how student academic performance can be improved by the adoption of specific behaviours by their lecturer

Purification of archetypal soybean root suberin mostly comprising alka(e)noic acids using an ionic liquid catalyst

Soybean (Glycine max) is an increasingly relevant crop due to its economic importance and also a model plant for the study of root symbiotic associations with nodule forming rhizobia. Plant polyesters mediate plant-microbe interactions with both pathogenic and beneficial microbes; suberin has been hypothesized to play a key role during the early steps of rhizobia attachment to the root. The downside is that suberin chemistry in soybean root is still scarcely studied. This study addresses this outstanding question by reporting a straightforward workflow for a speedy purification of suberin from soybean root and for its subsequent detailed chemical analysis. To purify suberin, cholinium hexanoate (an ionic liquid) was used as the catalyst. The ensuing suberin is highly esterified as observed by a precise Nuclear Magnetic Resonance quantification of each ester type, discriminating between primary and acylglycerol esters. Moreover, the composing hydrolysable monomers detected through GC-MS revealed that hexadecanoic acid is the most abundant monomer, similar to that reported before by others. Overall, this study highlights the adequacy of the ionic liquid catalyst for the isolation of suberin from soybean roots, where the polymer natural abundance is low, and builds new knowledge on the specificities of its chemistry; essential to better understand the biological roles of suberin in roots

Avaliação dos serviços hospitalares de emergência do estado do Rio de Janeiro Evaluation of emergency hospital services in the state of Rio de Janeiro

O presente estudo avalia as Unidades Hospitalares de Urgência/Emergência e registrou a relação da emergência com usuários, outros serviços do hospital e com a rede assistencial. Abordou a relação entre trabalhadores, a dimensão do seu quadro, formação e vencimentos. Relacionou a infra-estrutura cobrindo aspectos essenciais da organização, onde a assistência foi um dos componentes desse objeto mais amplo. Foi realizado um estudo descritivo com aplicação de questionário para os chefes de serviços, em uma amostra de 30 hospitais. Os depoimentos indicam que a ineficiência da atenção básica e da rede induzem à superlotação (que atingiu 80% dos hospitais), o que deteriora as condições de trabalho e assistência. O déficit de recursos humanos encontrado foi maior que o tecnológico. A precariedade dos vínculos empregatícios foi apontada como fator que dificulta a fixação e qualificação do profissional. Os itens melhor avaliados foram: relacionamento com chefia, confiança e expectativa com o serviço. Os piores foram salários, tamanho de equipe e medicina do trabalho. O investimento em recursos humanos é imprescindível. Há necessidade das políticas públicas articularem intervenções mais efetivas já que as vigentes definem a configuração dos territórios sanitários com suas redes hierarquizadas e solidárias.<br>This study aimed at the evaluation of urgency/emergency hospital units and recorded the relations of emergency units with users, other hospital services and the healthcare network and approached the size of the teams, the relations among the professionals, their qualification and income. It further describes the infrastructure of these services including basic organizational aspects. The aspect care was one component in this broader object. It is a descriptive study applying a questionnaire to the heads of the emergency services of a sample of 30 hospitals.The statements suggest the overcrowding of emergency services (in 80% of hospitals) deteriorating the work and care conditions to be due to the inefficiency of primary care and the healthcare network. The deficit of human resources was found larger than the lack of technology. The precarious employment relations were considered a factor hampering the qualification and retention of professionals. The most favorably evaluated items were: relationship with service heads, trust and expectations with regard to the service. The worst items were: wages, team size and labor medicine. The nvestment in human resources is indispensable. There is a need for public policies that articulate more efficient interventions given that those in force are defining the configuration of territories with their hierarchized and solidary networks
