O presente trabalho tem como objetivo geral estudar a gestão de recursos humanos (GRH) no terceiro setor, focando-se especificamente nas Instituições Particulares de Solidariedade Social (IPSS). Estas organizações têm vindo a demonstrar um papel cada vez mais relevante nas comunidades em que se inserem, pela sua missão em prestar serviços de cariz social e pela atual relevância como entidades empregadoras. A diversidade presente nas IPSS ao nível da estrutura, funcionamento, dimensão, organização e dinâmicas internas, proporciona o estudo e reflexão das especificidades na GRH. Para isso, abordam-se um conjunto de aspetos: i) diferenças entre meio empresarial e terceiro setor na GRH; ii) implicações da diversidade de respostas sociais e suas especificidades na gestão de pessoas; iii) o papel do Instituto de Segurança Social e as implicações legais na gestão de pessoas; iv) a localização geográfica e acesso a recursos humanos qualificados; v) a perspetiva das IPSS sobre os recursos humanos; vi) o perfil profissional dos colaboradores das IPSS; vii) práticas quotidianas na gestão de recursos humanos nas IPSS; viii) características da GRH nas IPSS (administrativa ou estratégica); ix) responsáveis pela GRH nas IPSS; x) o papel dos órgãos sociais na GRH; xi) profissionalização versus voluntariado; xii) a GRH, certificação e qualidade; xiii) as tendências do terceiro setor na gestão de pessoas. Foi utilizada uma metodologia qualitativa e aplicada a técnica de entrevista para recolher o conhecimento, experiências e perspetivas de diferentes interlocutores do terceiro setor, dirigentes, técnicos superiores, diretores de serviço, investigadores e representantes nacionais e distritais das IPSS. Da sistematização e análise dos dados recolhidos retiraram-se várias conclusões. As pessoas são consideradas o recurso mais importante para estas organizações, pela natureza social e humana das atividades desenvolvidas, prestadas por pessoas e destinadas a pessoas. Neste sentido, é demonstrada a importância do potencial humano aquando do recrutamento e seleção, pela primazia de requisitos como o relacionamento interpessoal em detrimento das qualificações. O perfil profissional característico das IPSS reconhece a importância da polivalência, disponibilidade, comprometimento, confiança, proximidade afetiva, voluntarismo e sentido de missão dos colaboradores, os quais tendem a ser são vistos como investimento tanto quanto reúnam estes aspetos; caso contrário podem ser encarados como custo. Quanto à acessibilidade a recursos humanos, surgem diferentes modalidades, consoante fatores de localização, dimensão, formação e estrutura organizacional, bem como o fenómeno da fuga de mão de obra, indício da dificuldade em captar e reter recursos humanos. O modelo de GRH nas IPSS é de cariz tradicional, caracterizado por uma gestão porimproviso com diferentes níveis de sensibilidade e capacidade das IPSS, no que concerne à implementação de processos de GRH, tais como sistemas de progressão na carreira, recrutamento interno e sistemas de avaliação de desempenho. Quanto aos aspetos da motivação e satisfação profissional, é assumida a importância da proximidade e apoio aos colaboradores, indicativos de um sistema de recompensas informal. É percetível a resistência na aplicação de técnicas de desenvolvimento organizacional, comprovada pela limitação na formação dos quadros de colaboradores. No entanto as IPSS são confrontadas com a rigidez dos instrumentos legais. A responsabilidade pela GRH é mais ou menos partilhada entre a direção técnica e os órgãos sociais, condicionada pelo estilo de liderança e relação de confiança entre si, em norma, pouco clara quanto aos papéis e funções desempenhadas. Por fim, é percebida a necessidade de coexistência de uma gestão profissionalizada e de direções voluntárias mais capacitadas e sensibilizadas para o desenvolvimento de metodologias e estratégias de gestão de pessoas, adaptadas às especificidades das IPSS. Este trabalho pretende contribuir com um espaço de reflexão para a elaboração de respostas mais eficazes e inovadoras que proporcionem o desenvolvimento organizacional, face às necessidades e transformações do terceiro setor. / This work main objective is the study of human resource management (HRM) in the third sector. It is focused specifically on Instituições Particulares de Solidariedade Social [Private Institutions for Social Solidarity] (IPSS). These kind of organizations have demonstrated an increased value in the communities they are inserted in, by providing social care services and by generating new jobs in the local communities. The study and reflection of HRM specificities is based on the variety in the structure, the purpose, the size, the internal organization and the dynamics of the different IPSS. For this purpose we explored the following aspects : i) the differences between business community and the third sector in HRM; ii) the implications of social responses diversity in people management; iii) the role of the National Insurance Institute and the legal impact on people management; iv) the geographic location and the IPSS access to skilled human resources; v) the understanding of IPSS on human resources; vi) the professional profile of IPSS employees; vii) the daily practices in human resource management on the IPSS; viii) the characteristics of HRM in IPSS (managerial or strategic); ix) who is responsible for HRM in IPSS; x) the role of executive board in HRM; xi) professionalization versus voluntary work; xii) HRM, quality and certification; xiii) the third sector trends in people management. The qualitative method and the interview technique were applied in order to gather knowledge, experiences and perspectives from several sources such as, different partners of the third sector, managers, service directors, technicians, researchers and national and local IPSS representatives. The results indicate several conclusions. Firstly the human resources are the most important resource of IPSS organizations due to the social nature of the services provided by them but also the importance of, the individual and social, skills required for these activities that are provided by people and are directed to people. This demonstrates the importance of interpersonal skills over professional qualifications during recruitment and selection. The IPSS recognize in their professionals the importance of versatility, availability, commitment, confidence, emotional proximity, voluntarism and sense of mission. If an employee fulfills these requirements, is considered an investment; otherwise might be seen as a cost. Regarding the accessibility of IPSS to qualified human resources, we consider different models, depending on location, size and training and organizational structure as well as the phenomenon run of hand labor, defined as the index of difficulty in capturing and retaining human resources. The model of HRM in IPSS is traditional in its nature and is characterized by management based on improvisation at different levels, regarding the implementation ofHRM processes such as career advancement systems, internal recruitment and performance evaluation. In regards to motivation and job satisfaction, it is valued the proximity and the support to the employees, showing therefore an informal system of rewards. There is a noticeable resistance to the application of organizational techniques which is demonstrated by controlling the formation of employees. However the IPSS are required to face the rigidity of legal instruments. The responsibility for HRM is shared between the technical direction and the management bodies, which depends on leadership style and mutual trust, and is generally unclear about the roles and duties performed. Finally, it becomes evident the need for coexistence between a professional management and a voluntary management, more capable and more sensible to the development of methods and strategies for people management, specifically adapted to each IPSS. This paper aims to contribute with space for reflection in the development of more effective and innovative responses for the organizational development, given the needs and transformations of the third sector.

Franchising is an important form of organizational control. Possible benefits of franchising include its ability to reduce agency costs that increase with costly monitoring, and provide incentives for the use of local information by onsite managers. However, these benefits may come at a cost, as franchisees may reduce quality by choosing to free ride. While many studies have investigated the reasons for franchising, few studies have documented the impacts of franchising on unit level operating performance. Using time-series data from a number of lodging properties that were converted to franchisee control from company control, this study documents the performance impacts of franchising. The analysis reveals that conversion results in a modest decline in financial performance and an immediate sharp decline in quality.

Résumé : Dans une ère de concurrence économique accrue, les organisations éprouvent de plus en plus le besoin de mesurer le rendement de leurs employés, y compris celui de leurs dirigeants. À cette fin, l'évaluation demeure un outil de gestion privilégié. Au nombre des systèmes d'évaluation existants, le feed-back multi-source (FMS) — ou feed-back 360°— est en progression. Malheureusement, on ne connaît pas encore très bien l'incidence de ce type de système, la littérature étant plutôt muette sur ce qu'il donne concrètement et, particulièrement, sur la réaction des évalués subséquemment à l'obtention de leur rapport d'évaluation. Il ressort néanmoins de certaines études que les dirigeants, et surtout, les chefs se sentent laissés à eux-mêmes quant à l'évaluation de leurs compétences. Il y a quelques années, à la demande du Groupement des chefs d'entreprise du Québec (GCEQ), un instrument de type multi-source a été conçu par le Laboratoire de recherche sur la performance des entreprises (LaRePe), afin de mesurer spécifiquement la performance des chefs d'entreprise comme leader. À ce stade-ci, les promoteurs désirent mieux comprendre l'incidence de l'utilisation de leur outil : le PDG-Leadership. Pour combler les lacunes de la littérature, et aussi pour répondre au besoin du GCEQ, la présente thèse porte sur la réaction des chefs à la suite de la réception de leur rapport d'évaluation. L'objet de la recherche est double : il s'agit d'examiner les variables qui influencent le fait que les évalués entreprennent des actions à la suite de leur feed-back (considération théorique) et, d'autre part, de connaître davantage ces actions entreprises bref, ce que le système de feed-back multi-source XFMS) donne vraiment (considération pratique). Afin de mener à bien la recherche, une résidence a été réalisée. Elle a fourni le contexte pour élaborer un questionnaire d'enquête s'appliquant particulièrement aux chefs d'entreprise. L'enquête a permis de rejoindre 351 dirigeants ayant été évalués au moins une fois par l'entremise du PDG-Leadership. De ce nombre, 87 répondants, membres du Groupement se sont manifestés. Le cadre conceptuel utilisé consiste en une adaptation du modèle proposé par Smither, London et Reilly (2005a). comporte sept variables, desquelles ont été tirées cinq hypothèses de recherche. Quatre hypothèses ont été rejetées alors qu'une autre ne s'est avérée supportée que pour le groupe constitué des femmes faisant partie de l'échantillon. De plus, il est intéressant de constater que ce n'est pas le feed-back (rapport) qui déclenche l'acceptation puis les actions, mais une attitude personnelle représentée par la possibilité d'un changement perçue (V4). Chez les chefs, il ne se produit donc pas de réaction en chaîne comme le suppose le modèle théorique utilisé. Il semble que ce soit plutôt la possibilité de changement perçu qui est à la base du fait d'entreprendre des actions, laquelle s'apparente au sentiment d'auto-efficacité défini par Bandura (2007). Les données recueillies auront aussi servies à générer de nouvelles connaissances et à faire ressortir une liste de 112 actions que les chefs disent avoir engagées à la suite de l'obtention de leur rapport d'évaluation. Cette liste a permis de faire une catégorisation des actions posées. Les actions qu'ils entreprennent sont toutefois davantage dirigées vers l'amélioration de l'organisation que vers leur propre amélioration. Il s'agit là, d'une des contributions de la présente thèse.||Abstract : In a context of intense economic competition, organizations are increasingly using instruments of performance evaluation. The multi-source feedback or 360 [degrees] is one of those. The literature seems still silent on what type of evaluation is really about the reaction it generates among evaluated. In response to a request from the Groupement des chefs d'entreprise du Québec (GCEQ), a System of multi-source assessment was designed by the Laboratoire de recherche sur la performance des entreprises (LaRePe). The PDG-Leadership, specifically used to measure the skills of managers of SMLs as a leader. After some years of use, developers want to better understand its impact in order to improve it and make it even better. To address these theoretical and practical considérations, a survey was conducted among 87 business leaders from Quebec who had already been assessed using this tool. This research bas the purpose, the validation of a preliminary model proposed by Smither, London, and Reilly, 2005a, to examine the variables that influence that evaluated undertake actions as a result of their feedback and the other, to know these actions, in short, that the System of feed-back multi-source (FMS) really. From the analysis of data collected, a list of 112 shares was established. In turn, this led to a categorization of actions taken. Although the FMS system is effective, it should be noted that entrepreneurs seem to react differently from other catégories assessed.

A smart solar photovoltaic grid system is an advent of innovation coherence of information and communications technology (ICT) with power systems control engineering via the internet [1]. This thesis designs and demonstrates a smart solar photovoltaic grid system that is selfhealing, environmental and consumer friendly, but also with the ability to accommodate other renewable sources of energy generation seamlessly, creating a healthy competitive energy industry and optimising energy assets efficiency. This thesis also presents the modelling of an efficient dynamic smart solar photovoltaic power grid system by exploring the maximum power point tracking efficiency, optimisation of the smart solar photovoltaic array through modelling and simulation to improve the quality of design for the solar photovoltaic module. In contrast, over the past decade quite promising results have been published in literature, most of which have not addressed the basis of the research questions in this thesis. The Levenberg-Marquardt and sparse based algorithms have proven to be very effective tools in helping to improve the quality of design for solar photovoltaic modules, minimising the possible relative errors in this thesis. Guided by theoretical and analytical reviews in literature, this research has carefully chosen the MatLab/Simulink software toolbox for modelling and simulation experiments performed on the static smart solar grid system. The auto-correlation coefficient results obtained from the modelling experiments give an accuracy of 99% with negligible mean square error (MSE), root mean square error (RMSE) and standard deviation. This thesis further explores the design and implementation of a robust real-time online solar photovoltaic monitoring system, establishing a comparative study of two solar photovoltaic tracking systems which provide remote access to the harvested energy data. This research made a landmark innovation in designing and implementing a unique approach for online remote access solar photovoltaic monitoring systems providing updated information of the energy produced by the solar photovoltaic module at the site location. In addressing the challenge of online solar photovoltaic monitoring systems, Darfon online data logger device has been systematically integrated into the design for a comparative study of the two solar photovoltaic tracking systems examined in this thesis. The site location for the comparative study of the solar photovoltaic tracking systems is at the National Kaohsiung University of Applied Sciences, Taiwan, R.O.C. The overall comparative energy output efficiency of the azimuthal-altitude dual-axis over the 450 stationary solar photovoltaic monitoring system as observed at the research location site is about 72% based on the total energy produced, estimated money saved and the amount of CO2 reduction achieved. Similarly, in comparing the total amount of energy produced by the two solar photovoltaic tracking systems, the overall daily generated energy for the month of July shows the effectiveness of the azimuthal-altitude tracking systems over the 450 stationary solar photovoltaic system. It was found that the azimuthal-altitude dual-axis tracking systems were about 68.43% efficient compared to the 450 stationary solar photovoltaic systems. Lastly, the overall comparative hourly energy efficiency of the azimuthal-altitude dual-axis over the 450 stationary solar photovoltaic energy system was found to be 74.2% efficient. Results from this research are quite promising and significant in satisfying the purpose of the research objectives and questions posed in the thesis. The new algorithms introduced in this research and the statistical measures applied to the modelling and simulation of a smart static solar photovoltaic grid system performance outperformed other previous works in reviewed literature. Based on this new implementation design of the online data logging systems for solar photovoltaic monitoring, it is possible for the first time to have online on-site information of the energy produced remotely, fault identification and rectification, maintenance and recovery time deployed as fast as possible. The results presented in this research as Internet of things (IoT) on smart solar grid systems are likely to offer real-life experiences especially both to the existing body of knowledge and the future solar photovoltaic energy industry irrespective of the study site location for the comparative solar photovoltaic tracking systems. While the thesis has contributed to the smart solar photovoltaic grid system, it has also highlighted areas of further research and the need to investigate more on improving the choice and quality design for solar photovoltaic modules. Finally, it has also made recommendations for further research in the minimization of the absolute or relative errors in the quality and design of the smart static solar photovoltaic module.

Queueing theory provides models, structural insights, problem solutions and algorithms to many application areas. Due to its practical applicability to production, manufacturing, home automation, communications technology, etc, more and more complex systems requires more elaborated models, tech- niques, algorithm, etc. need to be developed. Discrete-time models are very suitable in many situations and a feature that makes the analysis of discrete time systems technically more involved than its continuous time counterparts. In this paper we consider a discrete-time queueing system were failures in the server can occur as-well as priority messages. The possibility of failures of the server with general life time distribution is considered. We carry out an extensive study of the system by computing generating functions for the steady-state distribution of the number of messages in the queue and in the system. We also obtain generating functions for the stationary distribution of the busy period and sojourn times of a message in the server and in the system. Performance measures of the system are also provided.

As organizações em geral procuram alcançar objetivos, adotando estratégias que lhes permitam cumprir aquele desiderato com a máxima eficiência e eficácia. Os ramos das Forças Armadas procuram implementar a estratégia ao longo de um período que, face ao impacto das alterações entretanto verificadas, exige a capacidade para fazer ajustamentos àquela estratégia inicial. Nesse sentido, recorrem a ferramentas para avaliar o desempenho organizacional, que lhes permita saber qual o desempenho real e quais os ajustamentos necessários a fazer para alcançar esses objetivos. O objeto de estudo são as ferramentas de gestão estratégica utilizadas pelos ramos das Forças Armadas com o objetivo de analisar a sua pertinência, a sua eficiência na avaliação do desempenho organizacional e as diferenças relativamente ao Sistema Integrado de Gestão e Avaliação do Desempenho na Administração Pública (SIADAP). Seguiu-se uma estratégia de investigação qualitativa e um desenho de pesquisa comparativo, verificando-se que as ferramentas de gestão estratégica são pertinentes para a formulação e implementação da estratégia, são eficientes na avaliação do desempenho organizacional e diferenciam-se do SIADAP por integrarem a formulação, a implementação e a avaliação da estratégia segundo quatro perspetivas relevantes para o cumprimento da missão dos ramos das Forças Armadas. Abstract: The general organizations seek to achieve goals, adopting strategies that will enable them to fulfil that desideratum with maximum efficiency and effectiveness. The branches of the armed forces seek to implement the strategy over a period that address the impact of changes however checked, and it requires the ability to make adjustments to that initial strategy. In that sense, they use tools to assess organizational performance, enabling them to know what the actual performance and what adjustments needed to do to achieve those goals. The object of study are the strategic management tools used in the branches of the armed forces, with the aim of analysing their relevance, their effectiveness in assessing organizational performance and the differences from the Integrated Management and Performance Evaluation System in Public Administration (SIADAP). There was a qualitative research strategy and a comparative research design, verifying that the strategic management tools are relevant to the formulation and implementation of strategy, are effective in assessing organizational performance and differentiate SIADAP by integrating the formulation, implementation and evaluation of the strategy in four relevant perspectives to fulfil the mission of the branches of the armed forces.

O aumento da carga física do jogo de futebol provocou uma maior exigência e desenvolvimento na condição física dos jogadores e por inerência, nos árbitros. Assim o presente estudo procurou identificar e desenvolver um teste para a avaliação dos árbitros de futebol. Foi realizada uma análise sistemática para identificação e descrição da produção científica na área da arbitragem no sentido de sustentar o argumento de insuficiência dos testes vigentes e propor o novo teste que denominámos ETSOR. Após esta, foi realizada uma aplicação piloto com recurso ao método de estudo de caso para testagem do ETSOR. Os resultados revelaram que existe uma dispersão nas formas e conteúdos abordados face à caracterização do árbitro de futebol de 11. A partir do método de meta-análise, é apresentada uma proposta de categorização dos conteúdos. Os resultados revelaram também que o teste FIFA não identifica as intensidades irregulares que decorrem das situações do jogo, nem representa a uma distribuição das intensidades dos esforços dos árbitros nas situações de jogo. O Teste ETSOR, como teste ecológico, capta em termos de densidade, de distribuição, de variação da potência e de resistência, os esforços dos árbitros nas situações de jogo, como testa a características das intensidades máximas da atividade do árbitro. Por último, os resultados reforçaram que este processo que se deve estender de forma periodizada ao longo de cada época tornando-se útil, na medida em que permite a otimização e monitorização da prestação do árbitro.

Over the last few years, football entered in a period of accelerated access to large amount of match analysis data. Social networks have been adopted to reveal the structure and organization of the web of interactions, such as the players passing distribution tendencies. In this study we investigated the influence of ball possession characteristics in the competitive success of Spanish La Liga teams. The sample was composed by OPTA passing distribution raw data (n=269,055 passes) obtained from 380 matches involving all the 20 teams of the 2012/2013 season. Then, we generated 760 adjacency matrixes and their corresponding social networks using Node XL software. For each network we calculated three team performance measures to evaluate ball possession tendencies: graph density, average clustering and passing intensity. Three levels of competitive success were determined using two-step cluster analysis based on two input variables: the total points scored by each team and the scored per conceded goals ratio. Our analyses revealed significant differences between competitive performances on all the three team performance measures (p < .001). Bottom-ranked teams had less number of connected players (graph density) and triangulations (average clustering) than intermediate and top-ranked teams. However, all the three clusters diverged in terms of passing intensity, with top-ranked teams having higher number of passes per possession time, than intermediate and bottom-ranked teams. Finally, similarities and dissimilarities in team signatures of play between the 20 teams were displayed using Cohen’s effect size. In sum, findings suggest the competitive performance was influenced by the density and connectivity of the teams, mainly due to the way teams use their possession time to give intensity to their game.
