Este trabalho tem como objetivo identificar as variáveis que influenciam o uso do e-learning por alunos de um curso de graduação a distância de uma Instituição de Ensino Superior (IES). Foi identificado que o Modelo de Aceitação de Tecnologia (Technology Acceptance Model – TAM), de Davis (1989), com a introdução das variáveis externas interatividade e suporte técnico seria o mais adequado para avaliar a intenção do aluno em seguir usando o e-learning. Foi aplicado um questionário pela internet que resultou em uma amostra de 260 alunos. Os dados obtidos foram analisados por meio da Modelagem de Equações Estruturais (SEM) e os resultados confirmaram a validade de todas as hipóteses, confirmando a importância da interatividade e do suporte técnico para os alunos continuarem a usar o e-learning.
Dado o dinamismo imposto pelo ambiente empresarial, as empresas se veem impelidas a aperfeiçoar constantemente seu funcionamento, de forma a serem mais eficientes e produtivas. Diante desse cenário, o enfoque desta pesquisa foi avaliar a possibilidade de aplicação da metodologia COSO de controle interno ao setor de almoxarifado de uma empresa de médio porte, do segmento de transporte de passageiros e cargas. Para tanto, este estudo avaliou se os princípios da metodologia COSO são utilizados no controle interno do setor de almoxarifado de uma empresa de transportes, além de sugerir melhorias para o aperfeiçoamento do controle interno deste setor com base na referida metodologia. A pesquisa se deu por meio da pesquisa-avaliação, coletando dados a partir de observação direta e entrevistas. Os achados evidenciam que os controles são condizentes com a metodologia proposta; contudo, existem algumas melhorias a serem observadas quanto à comunicação corporativa interna e externa, bem como também em relação à qualificação e treinamento dos colaboradores.
A pandemia do coronavírus desestabilizou o modo de conviver e de trabalhar em diversos âmbitos, obrigando o mundo a procurar formas de adaptação a essa nova realidade. Nesse contexto, as organizações dos mais diversos setores da sociedade precisaram, por conta do isolamento social, migrar suas atividades para ambientes virtuais. O projeto Biblioteca Falada recorreu ao uso das Tecnologias de Informação e Comunicação (TIC) para a formação de novos canais de comunicação interna, visando a manutenção do trabalho. Assim, este trabalho tem como objetivo compreender, na experiência específica desta organização estudada, se e em que medida as atividades e os canais de comunicação adaptados para o contexto remoto possibilitam o funcionamento das atividades comunicativas e dos processos de produção, assim como o bom relacionamento com o público interno do projeto. Para tal, foi realizada uma pesquisa qualitativa para avaliação do uso dos canais estruturados durante a pandemia. Primeiramente, foram estudados materiais bibliográficos. Em seguida, realizou-se uma pesquisa documental no planejamento de comunicação interna da organização e aplicados questionários com questões sobre o uso dos canais propostos. Os resultados mostraram que existem especificidades para as estratégias de comunicação interna que devem ser pensadas respeitando as imposições do contexto pandêmico.
The present work aims to study the impact of O and N addition on Cr-sputtered coatings on plastic (polycarbonate, PC) used in automobile parts, as a promisor alternative for auto part metallization, while eliminating the usage of toxic hexavalent chromium. The coatings were deposited using DC magnetron sputtering from a single pure Cr target in a reactive atmosphere (N 2 and/or O 2 ). The deposition of the coatings was performed maintaining the total pressure constant and close to 1 Pa by tuning Ar pressure while reactive gases were added. The target current density was kept at J W = 20 mA·cm −2 . Structural characterization revealed a mixture of α-Cr, δ-Cr, β-Cr 2 N, and CrN crystalline structures as well as amorphous oxides. The coating hardness ranged from 9 GPa for the CrON coating to 15 GPa for the CrN coating. All deposited coatings showed a particularly good interface adhesion; adjusting the amount of O and N made it possible to tune the optical properties of the Cr-based coatings as desired. The promising results open future industrialization of sputtered Cr-based coatings for automotive industries. ; This work was supported by COMPETE 2020 a Portuguese and European Union initiative through the Project POCI-01-0247-FEDER-042785, acronym "GREENCoat".

International audience ; The global action plan (GAP) on antimicrobial resistance (AMR) advocated the development of national action plans on AMR and the implementation of plans aimed at preventing, combating and monitoring AMR. The World Organisation for Animal Health (OIE)'s strategy on AMR and the prudent use of antimicrobials is aligned with the GAP and recognizes the importance of a One Health approach. This paper reviews the goals, tools and strategies that the OIE has in place to support its Members, envisioning an increased awareness of them and ultimately an increased implementation of the OIE standards. The OIE standards are endorsed by vote of all the 182 Members and are recognized by the World Trade Organization (WTO). The OIE List of Antimicrobial Agents of Veterinary Importance, which includes specific recommendations on the use of antimicrobial agents, is also of particular importance for antimicrobial stewardship. OIE's antimicrobial use (AMU) data collection started in 2015 and has been developed in particular to measure trends in AMU. An annual report is published as an output of this data collection. An AMU IT database system is being developed. The OIE provides assistance to its 182 Members to strengthen the implementation of OIE standards via its support of good governance, the Performance of Veterinary Services (PVS) Pathway, PVS Veterinary Legislation Support Program and training of veterinarians and veterinary paraprofessionals. In parallel, the OIE Observatory is a recent initiative, specifically targeting the monitoring of the implementation of the OIE standards. Cooperation agreements between the OIE and intergovernmental organizations and non-governmental organizations are instrumental for the increase of the dissemination and implementation of the OIE standards and guidelines.

O estudo objetiva identificar os fatores que influenciam a intenção de docentes de uma instituição de ensino superior (IES) pública federal em continuar o uso do e-learning. Por meio de uma extensão do modelo TAM, incluindo tempo e autoeficácia como variáveis externas, foi possível verificar que a intenção em continuar o uso do e-learning é influenciada pela percepção de que a tecnologia pode contribuir para a melhoria do desempenho dos professores. Verificou-se que a intenção em continuar usando o e-learning pode não ocorrer de acordo com os pressupostos indicados pelo modelo TAM.
The objective of the study was to evaluate the main pre-slaughter factors contributing to bruising on cattle carcasses in the micro-region of Araguaína, Tocantins. The experiment was conducted from January to June using data from 414 cattle heads of different breeds, body weight and sex. Factors related to bruises in cattle were evaluated from the farms to a federally inspected slaughterhouse in Araguaína. The independent variables were road type, journey distance (paved and mixed roads), journey time (paved and mixed roads), driver's experience, prevalence of horns, sex class, falls during unloading, use of devices during unloading, truck maintenance conditions, presence of loose and/or protruding boards in the truck, condition of the truck floor, use of electric cattle prods during handling, presence of protruding nails and/or screws in the truck, arrangement of boards in the crowding pen, presence of broken boards in the cattle handling facility, angle of loading ramp, presence of protruding nails and/or screws in the cattle handling facility, and design and material of the cattle handling facility. The frequency of bruises was associated with the independent variables using contingency tables by the chi-square test (?2) to measure the association between variables. The variables road type, journey distance (mixed roads), journey time (mixed roads), animal behavior, falls during unloading, truck maintenance conditions, presence of loose and/or protruding boards in the truck, condition of the truck floor, arrangement of boards in the crowding pen, and presence of broken boards in the cattle handling facility had a significant effect on carcass bruising. Therefore, several pre-slaughter factors contribute to bruising on cattle carcasses.
