Aim: We compare the performance of major decision tree-based ensemble machine learning models on the task of COVID-19 death probability prediction, conditional on three risk factors: age group, sex and underlying comorbidity or disease, using the US Centers for Disease Control and Prevention (CDC)'s COVID-19 case surveillance dataset. Method: To evaluate the impact of the three risk factors on COVID-19 death probability, we extract and analyze the conditional probability profile produced by the best performing model. Result: The results show the presence of an exponential rise in death probability from COVID-19 with the age group, with males exhibiting a higher exponential growth rate than females, an effect that is stronger when an underlying comorbidity or disease is present, which also acts as an accelerator of COVID-19 death probability rise for both male and female subjects. These results are discussed in connection to healthcare and epidemiological concerns and in the degree to which they reinforce findings coming from other studies on COVID-19.

O referido instrumento contem 21 itens de comportamento de lideranca, e foi usado na avaliacao de 100 provas de situacao de grupos, ao longo da ultima decada. Apos a analise dos dados resultantes das avaliacoes, avaliamos a eficiencia do instrumento e construimos um novo instrumento com apenas 11 variaveis, que foi entao validado na avaliacao de 47 provas de situacao adicionais, criando uma nova base de dados. De acordo com os resultados, verificou-se que o novo intrumento de lideranca emergente permitiu reduzir a diferenca entre as avaliacoes quantitativas e qualitativas, mostrando-se potencialmente mais preciso. Desta observacao deduz-se que a reducao dos itens a monitorizar melhorou a avaliacao das provas de situacao de grupo, e contribuiu para o potencial decrescimo dos erros, distorcoes e enviseamento.

Contudo, as “soft skills” fazem a diferenca entre o “job well done” e as capacidades para obter desempenhos superiores em equipa, na integracao em cada organizacao e na sociedade em geral. Recentemente, o Ensino Superior em todo o mundo comecou a oferecer programas para o desenvolvimento de soft skills. No entanto, o caminho para desenvolver eficazmente as soft skills ainda esta por definir. Ao analisar os programas de treino para o desenvolvimento de soft skills no Ensino Superior verifica-se que as ofertas sao bastante diversificadas. Neste sentido, para definir um modelo de soft skills e os metodos pedagogicos que as promovem, este estudo tem como objetivo verificar se a pratica de equitacao representa um excelente instrumento. Para materializar estes objetivos, a investigacao usou o metodo quantitativo atraves da aplicacao de um questionario com 23 Soft Skills. A amostra foi constituida por 180 individuos (90 estudantes praticantes e 90 nao praticantes de equitacao) provenientes de tres Estabelecimentos Portugueses (Academia Militar, Universidade de Evora e Colegio Militar). Da analise dos resultados, conclui-se que existem diferencas na media dos valores do nivel de proficiencia das Soft Skills entre os estudantes praticantes e os nao praticantes da Academia Militar, Universidade de Evora e Colegio Militar. Os estudantes praticantes de equitacao mostram elevados niveis de proficiencia, nas seguintes Soft Skills: lideranca participativa; lideranca por delegacao; consideracao; autocontrolo; e promocao do desenvolvimento. Ainda, verifica-se que os estudantes praticantes de equitacao desenvolvem significativamente diferente dos nao praticantes todas as Soft Skills em estudo, com excecao para a autoconfianca e tomada de decisao.

The simultaneous detection of multiple potential biomarkers in sweat samples, using simple and low-cost electrochemical methods (detecting patterns or “electrochemical fingerprints”) requiring no sample preparation and its correlation with physiological conditions, is an attractive methodology but not readily achievable. Several of these potential biomarkers’ electrochemical response presents very close oxidation potentials, among other factors that hamper the detection, such as pH dependence of the electrochemical response or partial adsorption on electrode surfaces. Disposable screen-printed electrode materials, with relatively low-cost, could be useful to overcome the difficulties. A set of selected potential stress-related (non-protein) biomarkers (tyrosine, phenylalanine, dopamine, serotonin, and hydrocortisone) was used in the current study for qualitative electrochemical detection on different screen-printed carbon-based electrodes. The detection was attained in simulated sweat solutions and real sweat samples. The goal was to evaluate the electrochemical response on the different surfaces and determine the most suitable carbon-based screen-printed electrodes that may be used in future sensing devices.

Por isso, a capacidade para gerir o conhecimento a partir da experiencia � conhecimento tacito dos lideres com desempenhos superiores e transforma-la em referenciais de competencias � conhecimento explicito (aprendizagem e cultura organizacional) representa o desafio para qualquer organizacao. Este trabalho e realizado em contexto militar � Exercito Portugues e Guarda Nacional Republicana � estudo de caso, que a partir de 102 entrevistas realizadas aos lideres diretos, o principal objetivo e identificar competencias associadas a lideranca para obter desempenhos superiores. Numa primeira fase, a partir das entrevistas e feita a analise de conteudo � metodo qualitativo e utilizado um referencial com os seguintes dominios: (1) tracos de personalidade e atributos; (2) principios de lideranca; (3) e estilos de lideranca.

The research methodology used had three phases: bibliographical research; qualitative research, assessed through content analysis of a structured interview and quantitative research, which statistically analyzed data obtained from the application of a questionnaire, adapted by Rouco (2012). It has been found that the leadership competencies most used by the leaders of the PJ Units are transparency, human relationship, communication, interpersonal relations, technical and professional skills, decision making, guidance for the task, vision and, a competence not identified in the model: motivation. It was concluded that the leaders’ skills related to the management of the PJ Units, the existence of a vision, together with interpersonal re...

For this study, was used quantitative method and a survey was implemented comprising three questionnaires: one on leadership competences, one on communication styles, and one on with three criterion factors (extraordinary effort, group effectiveness and satisfaction). The survey was administered to a sample of 804 soldiers (30 Junior Officers, 81 Sergeants and 693 privates and corporals). The analysis of the data revealed that subordinates perceive that their commanders (junior officers) practice task oriented leadership behaviors, particularly on “orientation to the mission” and “decision making”. The behaviors exhibited by the officers strongly and positively relate with the “assertive” communicat...

Notwithstanding, the sampling methodology is critical, and it must be assessed prior to using sweat for clinical diagnosis. In the current work, the analytical methodology was further developed taking into account the sampling step, in view of the identification and level variations of sweat components that have potential to be stress biomarkers using separation by liquid chromatography and detection by tandem mass spectrometry, in order to attain a screening profile of 26 molecules in just one stage. As such, the molecule identification was used as a test for the evaluation of the sampling procedures, including the location on the body, using patches for long-term sampling and vials for direct sampling, through a qualitative approach. From this evaluation it was possible to conclude that the sampling may be performed on the chest or back skin. Additionally, p...

The research seeks to identify the role of the initial training course for professional firefighters in the proficiency level of leadership competences in trainees at the Lisbon Fire Service. To achieve the objectives of the investigation, the researchers adopted a quantitative method with a longitudinal case study research design, using a questionnaire of leadership competences, applied to 126 trainees of the Initial Training Course for professional firefighters from Lisbon Fire Service (case study), at three different moments during a one-year training period (longitudinal study). From the obtained results, it was concluded that the leadership competences with the highest level of proficiency at the end of the course are problem solving, participatory leadership, delegative leadership, conflict management, influence by example, task orie...
