The urgent need for sustainable waste management strategies has led to the exploration of innovative approaches for the valorization of waste. In this study, a method is proposed for carbonizing waste biomass materials, particularly paper mill waste sludges (primary and biological) and knots, to produce porous carbonaceous supports. Through an initial hydrothermal carbonization followed by carbonization with nitrogen flow, porous carbon materials are successfully generated. The findings of this investigation validate the successful generation of effective carbonaceous supports utilizing waste biomass materials. These materials are then evaluated for their effectiveness as porous supports in the ionic liquid‐catalyzed cycloaddition reaction of CO2 to styrene oxide, achieving a remarkable conversion rate of up to 98% and an impressive selectivity exceeding 99%. Additionally, the results underscore the significant impact of the selected IL on the overall conversion process. Overall, this study presents a promising pathway for the valorization of paper mill waste sludge through the production of porous carbon materials with potential applications in catalysis and beyond.

Among the non-pharmacological strategies, hydrotherapy (defined as the external application of water for therapeutic purposes) has been highlighted as an effective intervention for pain relief in childbirth. Within hydrotherapy, the application of warm shower stands out because it does not require prior training of women or a need for specific physical resources and can optimize the parturient/fetous, family birth experiences. Despite the scientific evidence, the availability and use of this strategy is not standardized in delivery rooms and in the practice of nurses/midwives. In this scenario it becomes important to consider the barriers and facilitators reported by nurses/midwives for this strategy implementation.

O presente relatório condensa o percurso pedagógico efetuado ao longo de dois anos letivos. Relativamente ao estudo, este procura compreender as conceções de Equidade de Género de estudantes do final do 2.º Ciclo do Ensino Básico. Nele são apresentados os conceitos fundamentais do estudo, as sequências didáticas implementadas nas diferentes etapas do estudo, os diferentes materiais pedagógicos desenvolvidos e o envolvimento da comunidade educativa. A investigação decorreu no ano letivo 2020/2021, durante a Prática de Ensino Supervisionada, com uma turma de 6.º ano de uma Escola Básica do concelho de Lagos. A recolha de dados foi realizada presencialmente e remotamente, devido à pandemia COVID-19 que se vivia no momento e que obrigou ao isolamento de estudantes. O estudo pretende responder às questões: Quais as perspetivas de equidade de género em alunos do 2º ciclo do Ensino Básico? ; De que forma podemos educar para a equidade de género no 2º ciclo do Ensino Básico?. A metodologia utilizada foi predominantemente qualitativa/interpretativa, visto o objetivo principal ser: conhecer a perspetiva dos/as estudantes do 2º ciclo em relação ao tema: equidade de género. Os resultados obtidos sugerem que os/as estudantes têm consciência de que existem desigualdades entre géneros, mas que têm vindo a ser atenuadas ao longo dos séculos. De um modo geral, verificou-se que todos/as compreendem as diferenças existentes nos direitos e deveres entre mulheres e homens, mas sobretudo ao nível monetário e no que diz respeito à realização de atividades domésticas. Analogamente comprovou-se que apesar dos/as alunos/as ouvirem comumente falar sobre o tema Igualdade de Género, estes/as têm enormes lacunas na explicitação de conceitos fundamentais. The present report condenses the pedagogical journey carried out over two school years. Regarding the study, it seeks to understand the conceptions of Gender Equity of students at the end of the 2nd cycle of basic education. It presents the fundamental concepts of the study, the didactic sequences implemented in the different stages of the study, the different pedagogical materials developed, and the involvement of the educational community. The research took place in the school year 2020/2021, during the Supervised Teaching Practice, with a 6th grade class of a Basic School in the municipality of Lagos. Data collection was carried out physically and remotely, due to the COVID-19 pandemic that was going on at the time and that forced the isolation of students. The study aims to answer the questions: What are the perspectives of gender equity in 2nd cycle elementary school students? ; How can we educate for gender equity in 2nd cycle elementary school?. The methodology used was predominantly qualitative/interpretative since the main objective was to know the perspective of 2nd cycle students regarding the theme: gender equity. The results obtained suggest that the students are aware that gender inequalities exist, but that they have been reduced over the centuries. In general, it was verified that all of them understand the differences existing in the rights and duties between women and men, but mainly in the monetary level and regarding the performance of domestic activities. Similarly, it was proven that although the students hear a lot about Gender Equality, they have enormous gaps in the explanation of the fundamental concepts.

O aumento das emissões de dióxido de carbono (CO2) é um facto alarmante que requer respostas urgentes da comunidade científica e das grandes empresas. Uma das soluções estudadas é a conversão de CO2 em carbonatos cíclicos. Para esta reação ocorrer sem condições agressivas, é necessário introduzir catalisadores produzidos, por exemplo, pela carbonização de resíduos à base de biomassa para a obtenção de carvões porosos. Enquanto algumas grandes empresas têm dificuldades em atuar perante estes problemas climatéricos, The Navigator Company, uma empresa líder na produção de papel, colaborou com este trabalho ao longo de seis meses na implementação dos seus resíduos para produzir catalisadores. Especificamente, lama primária, lama biológica e nós incozidos, cedidos pela The Navigator Company, foram comparados com quitosano comercial quanto à sua capacidade de serem precursores de carvões porosos. Também foram utilizados seis diferentes líquidos iónicos (LIs) como precursores devido às suas propriedades únicas. Os materiais de partida foram inicialmente carbonizados hidrotermicamente num reator Parr, seguindo uma carbonização com fluxo de azoto num forno tubular de alumina. As reações entre CO2 e óxido de estireno, utilizando os carvões sintetizados como catalisadores, foram realizadas num reator Parr. De modo a determinar o efeito dos LIs no rendimento da conversão e da carbonização, na percentagem de azoto, no grau de grafitização e na porosidade, os carvões foram caraterizados por análise elementar, Microscopia Eletrónica de Varrimento, isotérmicas de adsorção/deadsorção de azoto e por espetroscopia de Raman. O rendimento da conversão foi analisado por RMN 1H, de modo a determinar a eficiência catalítica dos carvões. Os resultados obtidos nesta dissertação confirmam não só a possibilidade de produção de catalisadores carbonosos a partir de resíduos à base de biomassa, com um rendimento de conversão máximo de 81% e seletividade >99%, mas também demonstram que a escolha do LI afeta diretamente o rendimento da conversão. The alarming rise in carbon dioxide (CO2) emissions has been met with urgent calls to the scientific community and global enterprises. One of the solutions relies on the conversion of CO2 into added-value products, such as cyclic carbonates. The catalysts required to counteract the inevitable harsh conversion reaction conditions may be found in the carbonization of waste biomass materials into porous carbons. While corporations struggle to take action against these climate-related issues, The Navigator Company, a leading Portuguese paper manufacturer, transparently and proactively collaborated with this sixmonth study of applied waste materials. Specifically, sludges and knots, kindly granted by The Navigator Company, were compared to commercially available chitosan, alongside six commercially available ionic liquids (ILs) with different anion/cation pairings for their potential as precursors to porous carbocatalysts. The ILs were selected for their use as templates, solvents, and catalysts as well as their unique properties (negligible vapor pressure, stability, and tunability). The synthesis on the carbon materials involved an initial hydrothermal carbonization in a Parr reactor, followed by carbonization with nitrogen flow in an alumina furnace. The cycloaddition reaction of CO2 to styrene oxide using the prepared carbocatalysts was carried out in a Parr reactor. To assess the effect of the ILs on the conversion reaction, on the carbonization yield, on the nitrogen content, on the degree of graphitization, and on the porosity, the resulting samples were characterized by elemental analysis, Scanning Electron Microscopy, nitrogen adsorption/desorption isotherms, and Raman spectroscopy. The catalytic potential of the obtained carbon materials was examined using 1H NMR spectra. Results of this study confirm efficient carbocatalyst production from waste biomass materials, with a maximum conversion of 81% and selectivity >99%, and further demonstrate that the choice of IL has a direct influence on the conversion. Further research will contribute to global demands for a circular economy.

Dissertação de mestrado em Contabilidade, Quando surgiu a profissão de contabilista, inicialmente esta era praticamente uma profissão masculina. Assim, existia a imagem de um contabilista como sendo um individuo conservador, monótono, atento aos detalhes e sobretudo associado a indivíduos do sexo masculino. As mulheres tiveram de lutar imenso e de ultrapassar diversos obstáculos para conseguir entrar na profissão. Atualmente, as mulheres já se encontram em maioria na profissão de contabilistas certificados, porém, apesar dos obstáculos que existiam no passado terem sido ultrapassados ou minimizados, ainda se verificam desigualdades, afetando assim a progressão da carreira das mulheres contabilistas. Aliás, a marginalização de contabilistas do sexo feminino e a natureza de género da profissão já se encontra investigada na literatura contabilística. Desta forma, com este estudo, pretende-se verificar qual a perceção que os contabilistas certificados têm do estereótipo da profissão e do estereótipo que lhes está associado, verificando se essa perceção é influenciada pela entrada de mulheres na profissão, assim como, perceber qual as principais dificuldades sentidas pelas mulheres no mercado de trabalho, analisando quais os principais obstáculos que podem dificultar a progressão da carreira das mulheres contabilistas. Para alcançar estes objetivos, foram realizadas onze entrevistas semiestruturadas a contabilistas certificados do sexo masculino e feminino a exercer a profissão atualmente. Nesse sentido, conseguiu-se concluir que a perceção da contabilidade e dos contabilistas não é alterada com a entrada da mulher na profissão. Relativamente às dificuldades sentidas as mulheres destacam sobretudo a maternidade e as tarefas de casa como fatores que lhes dificultam a conciliação da vida profissional com a pessoal, salientando que isso lhes poderá dificultar a progressão na carreira O estágio curricular foi realizado nas instalações da empresa Número Neiva, Lda, um gabinete de contabilidade com sede em Darque, Viana do Castelo, cuja atividade engloba os ramos de contabilidade, seguros, apoio jurídico e projetos de investimento. O estágio teve uma grande importância no meu processo de aprendizagem, na medida em que permitiu-me adquirir conhecimentos e competências para o desenvolvimento da profissão de Contabilista Certificado, assim como, permitiu-me aplicar os conhecimentos adquiridos no Mestrado em Contabilidade., When the accounting profession first started, it was practically a male profession. Thus, there was the image of an accountant as a conservative, monotonous individual, attentive to detail and especially associated to male individuals. Women had to fight a lot and overcome many obstacles to get into this profession. Women are now in majority in the profession of certified accountants, but although obstacles in the past have been overcome or minimized, inequalities still exist, affecting the career progression of women accountants. Incidentally, the marginalization of female accountants and the gendered nature of the profession is already investigated in the accounting literature. With this study, it is intended to verify the perception that certified accountants have about the stereotype of the profession and the associated stereotype as professionals, verifying if this perception is influenced by the admission of women in the profession, as well as to understand which are the main difficulties faced by women in the labor market, analyzing the main obstacles that may hinder the career progression of women accountants. To achieve these objectives, eleven semi-structured interviews were conducted with certified male and female accountants, currently practicing the profession. In this sense, it was concluded that the perception of accounting and accountants is not changed with the admission of women in the profession. Regarding the difficulties experienced, women highlight, above all, maternity and homework as factors that make it difficult for them to reconcile their professional and personal lives, emphasizing that this may hinder their career progression. The internship was carried out at the company Número Neiva, Lda, an accounting office based in Darque, Viana do Castelo, whose activity encompasses the branches of accounting, insurance, legal aid and investment projects. The internship was of great importance in my learning process, as it allowed me to acquire knowledge and skills for the development of the profession of Certified Accountant, as well as allowing me to apply the knowledge acquired in the Master of Accounting.

Aim: Bring to discussion spiritual leadership and workplace spirituality on a health care system that faces constant challenges and seeks constant adaptations, as a way to guarantee nurses' well‐being and quality of care. Background: The work environment has shown to have impact on staff well‐being. Workplace spirituality relates to sense of belonging, motivation and commitment. A spiritual leadership is fundamental to develop workplace spirituality. Evaluation: Starting from literature, a reflection on the theme was carried out based on the results of the development of spiritual leadership and workplace spirituality in health care institutions, in professionals and in patients. Key issues: Nurses have spiritual needs which need to be also addressed in order to promote the sense of identification with the institutions' vision and goals. A relation between spiritual leadership, workplace spirituality and subjective well‐being is often found in literature, and this is critical evidence towards new management and leadership dynamics and models in health care institutions that should integrate workplace spirituality. Conclusion: Nursing leaders are responsible for workplace spirituality facilitation. Nursing leadership and workplace spirituality seem both an answer and way to the change of health institutions management paradigm, but more studies are needed to inform this change in practice. Implications for Nursing Management: Workplace spirituality must be promoted in all health care institutions, aiming the humanization of care and teams.Nursing leaders must have spiritual competences and must include the promotion of workplace spirituality in daily agenda as a foundational area in management.The health care institutions' managers should consider the best leaders who should facilitate workplace spirituality.

Dissertação de Mestrado em Ensino de Educação Física, nos Ensinos Básico e Secundário Nas últimas décadas temos assistido em todo o mundo, a um aumento da obesidade a uma velocidade aterradora, o que a tornou uma das mais recentes epidemias à escala mundial, cuja prevalência aumenta particularmente nas crianças e adolescentes. Vários estudos comprovam que a forma como os jovens ocupam os seus tempos livres (actividades sedentárias e exercício físico) e a imagem corporal que têm de si próprios (percepcionada e insatisfação) estão relacionados com a obesidade. Desta forma, este estudo teve como objectivo relacionar a ocupação dos tempos livres e a percepção da imagem corporal com a obesidade. A amostra é constituída por 529 jovens, 284 do sexo masculino e 245 do feminino com idades decimais compreendidas entre os 10,47 e os 17,29 anos (13,26±1,59). Para a recolha de dados, relativamente à ocupação dos tempos livres, prática de exercício físico e imagem corporal, foi utilizado um questionário, baseado no questionário de Health Behaviour in School-aged Children (HBSC) e já utilizado em vários estudos no âmbito do projecto de Estratégias Locais de Saúde (ELSa). Na avaliação da percepção da imagem corporal foi utilizado o conjunto de silhuetas de Collins e para o cálculo do Índice de Massa Corporal (IMC) foram recolhidos o peso e a altura e utilizados os valores de corte de Cole et al. para definir o grau de obesidade. Como resultados do nosso estudo verificamos que existem diferenças, estatisticamente, significativas na imagem corporal percepcionada segundo a prevalência de obesidade (p=0,000) e na insatisfação da imagem corporal segundo a prevalência de obesidade (p=0,000). Os indivíduos obesos percepcionaram-se como mais gordos e sentem-se mais insatisfeitos com a imagem corporal do que os normoponderais, principalmente pelo excesso de peso. Relativamente às actividades de tempos livres verificaram-se diferenças, estatisticamente, significativas segundo o sexo nas actividades: número de horas que jogam jogos durante a semana e ao fim-de-semana, que estão na internet durante a semana e ao fim-de-semana, estão com os amigos durante a semana e ao fim-de-semana. Os rapazes apresentam valores mais elevados nos jogos electrónicos à semana 3,01 (±1,61) e ao fim-de-semana 3,31 (±1,65), na internet à semana 3,46 (±1,63) e ao fim-de-semana 3,49 (±1,67) e no número de horas que estão com os amigos ao fim-de-semana 3,31 (±1,65). Também se verificaram diferenças estatisticamente significativas nas actividades de tempos livres segundo os ciclos de ensino, no número de horas que vêem televisão durante a semana e ao fim-de-semana, na internet durante a semana e ao fim-de-semana, a estudar ao fim-de-semana e no estar com os amigos ao fim-de-semana. Verificou-se que em todas estas actividades os alunos do 3º ciclo apresentam valores mais altos, à excepção de estudar ao fim-de-semana em que os alunos do 2º ciclo apresentaram valores superiores. Ao analisar a prática de exercício físico verificaram-se diferenças estatisticamente significativas segundo o sexo (p=0,000) e segundo os ciclos de ensino (p=0,000). A maioria dos rapazes e os alunos do 3º ciclo praticam mais horas de exercício físico por semana. A imagem percepcionada e a insatisfação com a imagem corporal foram as únicas variáveis que se relacionaram com a obesidade nos jovens. As estratégias de intervenção para a redução da obesidade devem contemplar também a promoção de uma imagem corporal positiva. In recent decades we have assisted all over the world to the development of obesity at a terrifying rate, which made it one of the recent pandemic worldwide, whose prevalence increases particularly in children and adolescents Multiple studies prove that the way young people occupy their leisure time (sedentary activities and physical exercise) and body image that have themselves (perceived and insatisfaction) are related to obesity. Thus, this study aimed to relate the occupation of leisure time and the perception of body image with obesity. The sample consists of 529 young people, 284 male and 245 female with decimals ages between 10.47 and 17.29 years (13.26 ± 1.59). For the collection of data regarding the occupation of leisure time, the practice of physical exercise and body image, was used a questionnaire, based on questionnaire of Health Behaviour in School-aged Children (HBSC) and already used in several studies within the framework of the project Estratégias Locais de Saúde (ELSa). In assessing the perception of body image was used the set of silhouettes of Collins and the calculation of body mass index (BMI) were collected the weight and height and used the cutting values of Cole et al. to define the degree of obesity. As results of our study we verify that there are differences, statistically significant, in body image perceived according to the prevalence of obesity (p=0.000) and body image dissatisfaction according to the prevalence of obesity (p=0.000). The obese individuals perceptioned himselves as fatter and they feel more dissatisfied with body image than the normal weight, mainly by excess weight. Relatively to the leisure activities were verify differences statistically significant according to sex type in the activities: number of hours playing games during the week and at weekends, which are on the internet during the week and at weekends, are with friends during the week and at weekends. The boys have higher values in playing electronic games at the week 3.01 (± 1.61) and at the weekend 3.31 (± 1.65), on the internet at the week 3.46 (± 1.63) and at the weekend 3.49 (± 1.67) and on the number of hours that are with the friends at the weekend 3.31 (± 1.65). Also there were diferences statistically significant in leisure activities in accordance with the educational cycles, in the number of hours they see television during the week and at weekends, on the internet during the week and at weekends, studying at the weekend and be with friends at weekends. It was found that in all these activities students of 3rd cycle have higher values, with the exception of study at the weekend in which students of 2nd cycle showed higher values. To analyze the practice of physical exercise were verified diferences statistically significant according to sex type (p=0.000) and according the cycles of higher education (p=0.000). Most boys and 3rd cycle students practice more hours of exercise per week. The image perceived and insatisfaction with body image were the only variables that related with obesity in young people. The intervention strategies to reduce obesity should include also the promotion of a positive body image.

Dissertação, Mestrado, Contabilidade e Finanças, Instituto Politécnico de Santarém, Escola Superior de Gestão e Tecnologia, 2014 nvestir no setor imobiliário residencial requer uma análise cuidada de certas variáveis (ou determinantes). Tratando-se de um setor fundamental para o desenvolvimento económico e social, e face à atual conjuntura económica, a análise do risco de investimento é tida como fundamental no processo de apoio à tomada de decisão no que respeita à compra e venda de bens imóveis. Neste sentido, e tendo por base a literatura da especialidade e as aplicações empíricas reportadas, o estudo desenvolvido visa conceber um modelo conceptual de referência que, com recurso a técnicas difusas de mapeamento cognitivo (i.e. fuzzy cognitive mapping), sirva de suporte à identificação e compreensão das relações de causalidade entre determinantes de análise de risco de investimento em bens imóveis residenciais. O recurso a este tipo de abordagem é explicado pelo facto de os mapas cognitivos permitirem reduzir o número de critérios omitidos, favorecerem a aprendizagem da forma como esses mesmos critérios se relacionam entre si e serem, ainda, reconhecidos pela sua versatilidade no apoio à estruturação de problemas complexos. Face ao exposto, e por se tratar de uma abordagem próxima do domínio das redes neuronais e da inteligência artificial, parece evidente que uma proposta metodológica que acrescente valor, via simplicidade e transparência, ao processo de análise do risco deste tipo de investimento, seja de grande importância e constitua a base do estudo a desenvolver.

The industrial use of fossil fuels is a human activity affecting soil and the carbon-cycle in the vicinity of utilization facilities. The combustion of coal for power generation is a known source of contaminants that may pose risk to soils. Once in the soil, contaminants can be concentrated or mobilized back to the atmosphere, made available to biota, leached to surface water bodies and aquifers, or transported to other areas by soil erosion. This research aims the petrographic identification of contaminants particles in soils nearby Sines coal-fired thermal power plant, in Portugal, which was recently decommissioned. This site was selected for study because the industrial activity based on coal combustion lasted for decades, between 1985-2021, and during this period the impact on soil in the surrounding area was never investigated. Besides, it is located in an environmentally sensitive area since it is adjacent to a natural park and to the coast of Atlantic Ocean. According to the geological context, the natural soil occurring in the area is classified as arenosol. A total of 27 superficial soil samples (from 0 to 10 cm depth after removal of vegetation debris and gravel) were collected around the outer limit of the entire complex of the power plant facilities. Field observations during sampling reveal that some ash could be mixed with soil or buried in some restricted places in the sampled area and, in these cases, the distinctive material was also collected. One sample was collected farther (~ 750 m) to the study area but with the same geological background, representing a local reference sample. After sieving, the sample fraction finer than 2 mm was used to prepare polished blocks. The microscopic observations were performed under incident white light and with an oil immersive objective. The identification of organic particles followed the ICCP nomenclature. The petrographic analysis of the reference soil sample allows the observation of organic matter particles of natural origin together with the mineral matter, principally composed of silicates. The microscopic observation of soil samples allows the identification of contaminant coal particles and combustion-derived particles in some samples (char, amorphous agglomerates, and magnetic and glass spheres), being more abundant in the proximity of old storage and disposal sites of coal and coal combustion by-products, respectively, and the area towards the prevailing wind direction (from N-NW to S-SE). The petrographic study also proved the presence of coal-ash, below the superficial soil layer in a specific and spatially limited place. Further work should include the expansion of the soil sampling grid (either in depth and laterally) to define the spatial extent of the contamination left by the coal use in the decommissioned coal-fired thermal power plant.

Mestrado em Comunicação Multimédia A presente dissertação tem como objetivo explorar novos paradigmas para Serious Games em interface tangível, com vista a promover a aprendizagem não formal das ciências junto de crianças dos 5 aos 12 anos de idade. É composta por uma vertente teórica que enquadra o trabalho e uma vertente mais prática, onde é desenvolvido o jogo através da metodologia participatory design, posteriormente avaliado com recurso à metodologia observacional. É também proposta uma reformulação no design da instalação multimédia interativa IMP.cubed, projeto da Universidade de Aveiro em parceria com a Universidade de Concordia, Montreal, Canadá. Neste contexto, esta dissertação abrange uma vasta panóplia de áreas do conhecimento, nomeadamente: a) as teorias da aprendizagem, que ajudam a caracterizar o público-alvo; b) as teorias de jogos e Serious Games, que apoiam no desenvolvimento do jogo; c) o design de jogos e de instalações multimédia, que permitem a execução. Uma avaliação preliminar das sessões de participatory design revelou que as crianças se sentem bastante participativas aquando envolvidas num projeto deste género. Paralelamente, é mais fácil ir ao encontro das suas expectativas conhecendo-as à partida. A avaliação final do protótipo revelou fragilidades na tecnologia, mas elevadas potencialidades para a motivação na aprendizagem não formal das ciências e outras áreas que se possam vir a adicionar na instalação. The present thesis has the main aim to explore new paradigms for Serious Games in tangible interfaces, in order to promote non-formal scientific learning among children from ages 5 to 12 years old. It is composed of both a theoretical and also practical model, where a game is developed through a participatory design methodology, then evaluated with the use of an observational method. It is also suggested an intervention in renovating the design of the interactive multimedia installation IMP.cubed, a project of the University of Aveiro in partnership with Concordia University, Montreal, Canada. In this context, this work covers a wide range of knowledge areas, that includes: a) learning theories that help to portray the target audience, b) game and Serious Games theories, which support the development of the game; c ) the design of game and multimedia installations which allows its execution. A preliminary assessment of participatory design sessions revealed that children feel pretty much involved in a project of this kind. Moreover, it is easier to meet their expectations knowing them in advance. The final evaluation of the prototype has highlighted weaknesses in the technology used, but high potential for motivation in non-formal scientific learning and other areas that might be supplementary in these types of installations.

Mestrado em Ciências Acturiais Em Portugal, a tarifa de acidentes de trabalho baseia-se na aplicação de uma taxa à massa salarial anual de uma empresa. Esta taxa varia mediante o sector de actividade, uma vez que este explica as diferenças de frequência e do montante das indemnizações. A ocorrência de um acidente de trabalho desencadeia diferentes prestações: em espécie e em dinheiro. No entanto, a variável explicativa paxa a tarifação é somente a massa salarial, apesar de as prestações em espécie dependerem mais do número de pessoas seguras do que dos salários das mesmas. Neste trabalho, apresenta-se uma tarifa que assume como variáveis explicativas o número de pessoas seguras e a massa salarial, considerando igualmente, o código de actividade económica como critério de classificação à priori. Inicialmente, para a obtenção desta tarifa, pensou-se no modelo colectivo de risco que, mais tarde, se verificou não ser possível aplicar. Recorreu-se então ao modelo regressional que, com o auxilio da técnica da semi-linearização, permitiu obter uma tarifa para este ramo do sector segurador. In Portugal, the workers compensation tariff is based in the application of a rate to the total annual wages of each enterprise. This rate varies according to the sector of economic activity since it has been proved that the sector explains the differences found in tenns of the frequency and amount of the indemnizations. The occurrence of a work accident leads to different kinds of allowances: monetary and in species. Even though the allowances in species are usually better associated with the number of insured workers, the wages are the solely controlled variable used in the calculation of the tariff. In this work, it is presented a tariff that assumes the number of insured workers and the wages as its controlled variables. The sector of economic activity is also considered as an a priori criterion of classification. Initially, to obtain this tariff, it was though to use the Collective Risk Model that, latter on, proved to be inapplicable. The final option was to use the semi-linearization technique applied to the regression model with which was obtained a tariff for this branch of the insurance sector. info:eu-repo/semantics/publishedVersion
