Abstract: As empresas familiares estão presentes mundialmente, contribuindo positivamente para a economia, criação de riqueza e emprego. A continuidade destas empresas depende essencialmente da sua sucessão. Neste trabalho é apresentado um enquadramento teórico sobre a sucessão das empresas familiares, o que deve ser feito e os principais erros. Posteriormente, é feito um levantamento sobre a sucessão das empresas familiares da região de Leiria, em Portugal. Por fim, é analisado o impacto da geração da empresa e da existência de gestores não familiares no endividamento destas empresas. Os resultados evidenciam que a maioria das empresas se encontra na geração do fundador e que os gestores são maioritariamente familiares. Porém, uma percentagem de 45% dos inquiridos já se preocupou com a sucessão e elaborou um plano, embora o tenha feito maioritariamente sem o apoio de especialistas na área. Por fim, a geração da empresa e o tipo de gestor não tem impacto no endividamento destas empresas.

Abstract: Uma das dificuldades associadas à realização de investigação qualitativa remete para a dimensão das amostras. Com alguma frequência, os investigadores não justificam a sua escolha de N e são por isso criticados. Este artigo apresenta linhas de orientação para a determinação e justificação do número de casos a usar numa investigação qualitativa. Defende que (a) o aumento da dimensão da amostra não é, em si, uma vantagem, e (b) a quantidade desejável de casos da amostra depende da pergunta de investigação e da declinação da mesma numa série de linhas orientadoras.

Abstract: Embora a literatura existente apelide o setor de consultoria de gestão como um setor extraordinário e um fenómeno único no contexto empresarial, na verdade, estas afirmações não vêm acompanhadas por um número de estudos académicos que realcem a importância do trabalho efetivo dos consultores de gestão. Para combater a falta de estudos nesta área emergente, este artigo visa construir um modelo que permita combinar, numa mesma estrutura, os papéis dos consultores de gestão, as variáveis a equacionar em cada um destes papéis e o tipo de consultoria implícita em cada uma destas análises. Os resultados da análise empírica sob a forma de entrevistas semiestruturadas e questionários aplicados a consultores de gestão e gestores de PME em Portugal demonstram que os papéis dos consultores não podem ser apenas definidos nas variáveis visibilidade organizacional e estatuto do consultor.

Abstract: Falhas assistenciais podem comprometer a segurança de pacientes. No hospital, em especial na Unidade de Terapia Intensiva (UTI), a gestão de operações depende de tarefas administrativas, mas não foi estudado até então seu papel na segurança de pacientes. Esta pesquisa analisou incidentes decorrentes de falhas administrativas em pacientes internados em UTI com abordagem empírica de caráter exploratório-descritivo e estratégia de pesquisa-ação. Detectamos 653 incidentes decorrentes de falhas administrativas (6,94%), sendo 280 eventos adversos (42,8%). A ocorrência de falhas administrativas prolongou internação na UTI em 1,84 dias, (p<0,0005) e no hospital (p=0,002). A maioria dos incidentes (99,3%) era evitável. O gestor pode atuar neste cenário monitorando tarefas administrativas de risco à segurança do paciente usando diferentes ferramentas e até preveni-las, colocando barreiras buscando melhoria da qualidade e maior eficiência operacional.

Abstract: Cardiovascular diseases are the major cause of mortality, with 17.9 million deaths/year worldwide and 3.9 million deaths/year in Europe, representing a cost to the EU economy of €210 billion/year [1,2]. Arterial stiffness has been shown to increase cardiovascular morbidity and mortality [3,4]. It is a complex phenomenon characterized by decreased vascular distensibility [5]. This degenerative process is influenced by ageing and several risk factors but is mainly associated with changes in the extracellular components of elastic arteries [5,6]. Several factors, including vascular function, oxidative stress, inflammation, glycation and autophagy contribute to the pathophysiology of arterial stiffness. Considering that the structural degeneration of the extracellular matrix of the vascular wall is practically irreversible with current therapies, it is extremely important to evaluate the impact of preventive interventions, for example reducing the impact of aging on increasing stiffness [5]. Most cardiovascular diseases can be prevented by addressing behavioral risk factors, of which dietary factors make the largest contribution [2]. Polyphenols are a widespread class of plant secondary metabolites that are found in several foods and possess a diverse range of biological activities. Dietary polyphenols display pleiotropic effects, interacting with most mechanisms involved in arterial stiffness etiology. Therefore, they could constitute an interesting option to target vascular stiffening. In vivo activity of polyphenols or polyphenol containing foods is known [7]. For several polyphenols or polyphenol containing foods, including cocoa, grapes, berries and olive, intervention studies point to a beneficial effect on vascular stiffness [8–12]. With regard to olive polyphenols specifically, our previous intervention study has shown blood pressure lowering effects [12–15]. In order to further elucidate mechanisms of action, we recently focused on specific studies investigating the potency of olive polyphenols as autophagy-inducing compounds, and the contribution of this mechanism to their atheroprotective effects.

Abstract: Background and objectives: Modern-day epidemiologic data on the risk and shifting landscape of occurrence of cardiovascular events in cannabis users remain inadequate and rather conflicting, especially amongst the young adult population. Furthermore, the problem of polysubstance use among youth is challenging for healthcare professionals and policy-makers. Previous studies report higher risk of concomitant use of tobacco, alcohol, cocaine, and amphetamine in young cannabis users. However, most of these studies did not eliminate the confounding effects of concomitant other substance abuse while assessing the incidence and outcome of cardiovascular events in cannabis users. Materials and methods: Using weighted discharge records from the National Inpatient Sample (NIS) from 2007–2014, we assessed the national trends in hospitalizations for major cardiovascular events including acute myocardial infarction (AMI), arrhythmia, stroke, and venous thromboembolic events (VTE) among young cannabis users (18–39 years), excluding cases with concomitant substance abuse with alcohol, tobacco, cocaine, and amphetamine. Results: Of 52.3 million hospitalizations without other substance abuse, 0.7 million (1.3%) young adults were current/former cannabis users. Among young adults without concomitant substance abuse, the frequency of admissions for AMI (0.23% vs. 0.14%), arrhythmia (4.02% vs. 2.84%), and stroke (0.33% vs. 0.26%) was higher in cannabis users as compared to non-users (p < 0.001). However, the frequency of admissions for VTE (0.53% vs. 0.84%) was lower among cannabis users as compared non-users. Between 2007 and 2014, we observed 50%, 79%, 300%, and 75% relative increases in hospitalizations for AMI, arrhythmias, stroke, and VTE, respectively, among young cannabis users as compared to non-users, showing relatively inferior or no ascent in the rates (ptrend < 0.001). Conclusions: The rising trends in hospitalizations for acute cardiovascular events among young cannabis users without concomitant other substance abuse call for future prospective well-designed studies to assess cannabis-related short-and long-term cardiovascular implications while simultaneously developing focused interventions towards raising awareness among the young population regarding the potential deleterious effects of cannabis use.

Abstract: A comparison of two open source electroencephalography devices designed to acquire signals associated to the brain activity is presented in this work. The experiments are developed considering the task of determining the user eye state i.e., open eyes or closed eyes, applying an algorithm based on computing the sliding Fourier Transform of the captured signals.

Abstract: Communication network data has been growing in the last decades and with the generalisation of the Internet of Things (IoT) its growth has increased. The number of attacks to this kind of infrastructures have also increased due to the relevance they are gaining. As a result, it is vital to guarantee an adequate level of security and to detect threats as soon as possible. Classical methods emphasise in detection but not taking into account the number of records needed to successfully identify an attack. To achieve this, time-aware techniques both for detection and measure may be used. In this work, well-known machine learning methods will be explored to detect attacks based on public datasets. In order to obtain the performance, classic metrics will be used but also the number of elements processed will be taken into account in order to determine a time-aware performance of the method.

Abstract: Knowledge of soil water at a range of spatial scales would further our understanding of the dynamic variable and its influence on numerous hydrological applications. Cosmic ray neutron technology currently consists of the Cosmic Ray Neutron Sensor (CRNS) and the Cosmic Ray Neutron Rover (CRNR). The CRNR is an innovative tool to map surface soil water across the land surface. This research assessed the calibration and validation of the CRNR at two survey sites (hygrophilous grassland and pine forest) within the Vasi area with an area of 72 and 56 ha, respectively. The assessment of the calibrations showed that consistent calibration values (N0) were obtained for both survey sites. The hygrophilous grassland site had an average N0 value of 133.441 counts per minute (cpm) and an average error of 2.034 cpm. The pine site had an average N0 value of 132.668 cpm and an average error of 0.375 cpm between surveys. The validation of CRNR soil water estimates with interpolated hydro-sense soil water estimates showed that the CRNR can provide spatial estimates of soil water across the landscape. The hydro-sense and CRNR soil water estimates had a R2 of 0.439 at the hygrophilous grassland site and 0.793 at the pine site.
