An Empirical Analysis of Performance Impacts Resulting From Conversion to Franchise Operations

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.

Conception et caractérisation d'un dosimètre à fibre scintillante pour des applications en imagerie diagnostique et interventionnelle

Cette thèse a pour sujet le développement d’un détecteur à fibre scintillante plastique pour la dosimétrie des faisceaux de photons de basses énergies. L’objectif principal du projet consiste à concevoir et caractériser cet instrument en vue de mesurer la dose de radiation reçue au cours des examens d’imagerie diagnostique et interventionnelle. La première section est consacrée à la conception de six différents systèmes et à l’évaluation de leur performance lorsqu’ils sont exposés à des rayonnements de hautes et basses énergies. Tous les systèmes évalués présentaient un écart type relatif (RSD) de moins de 5 % lorsqu’ils étaient exposés à des débits de dose de plus de 3 mGy/s. Cette approche systématique a permis de déterminer que le tube photomultiplicateur répondait le mieux aux conditions d’exposition propres à la radiologie. Ce dernier présentait une RSD de moins de 1 % lorsque le débit de dose était inférieur à 0.10 mGy/s. L’étude des résultats permis également de suggérer quelques recommandations dans le choix d’un système en fonction de l’application recherchée. La seconde partie concerne l’application de ce détecteur à la radiologie interventionnelle en procédant à des mesures de dose à la surface d’un fantôme anthropomorphique. Ainsi, plusieurs situations cliniques ont été reproduites afin d’observer la précision et la fiabilité du détecteur. Ce dernier conserva une RSD inférieure à 2 % lorsque le débit de dose était supérieur à 3 mGy/min et d’environ 10 % au débit le plus faible (0.25 mGy/min). Les mesures sur fantôme montrèrent une différence de moins de 4 % entre les mesures du détecteur et celles d’une chambre d’ionisation lors du déplacement de la table ou du bras de l’appareil de fluoroscopie. Par ailleurs, cette différence est demeurée sous les 2 % lors des mesures de débit de dose en profondeur. Le dernier sujet de cette thèse porta sur les fondements physiques de la scintillation dans les scintillateurs plastiques. Les différents facteurs influençant l’émission lumineuse ont été analysés afin d’identifier leur contribution respective. Ainsi, la réponse du détecteur augmente de près d’un facteur 4 entre un faisceau de 20 kVp et 250 kVp. De ce signal, la contribution de la fluorescence produite dans la fibre claire était inférieure à 0.5 % lorsque les fibres étaient exposées sur 10 cm par des faisceaux de 20 à 250 kVp. Le phénomène d’extinction de la fluorescence par ionisation a également été étudié. Ainsi, l’atténuation du signal variait en fonction de l’énergie du faisceau et atteignit environ 20 % pour un faisceau de 20 kVp. En conclusion, cette étude suggère que les détecteurs à fibres scintillantes peuvent mesurer avec précision la dose de radiation reçue en imagerie diagnostique et interventionnelle, mais une calibration rigoureuse s’avère essentielle.

Réactions du chef de PME après utilisation d'un système d'évaluation multi-source

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.

Evaluation of online higher education: learning, interaction and technology

The work presents a theoretical framework for the evaluation of e-Teaching that aims at positioning the online activities designed and developed by the teacher as to the Learning, Interaction and Technology Dimensions. The theoretical research that underlies the study was developed reflecting current thinking on the promotion of quality of teaching and of the integration of information and communication tools into the curriculum in Higher Education (HE), i.e., bearing in mind some European guidelines and policies on this subject. This way, an answer was sought to be given to one of the aims put forward in this study, namely to contribute towards the development of a conceptual framework to support research on evaluation of e-teaching in the context of HE. Based on the theoretical research carried out, an evaluation tool (SCAI) was designed, which integrates the two questionnaires developed to collect the teachers' and the students' perceptions regarding the development of e-activities. Consequently, an empirical study was structured and carried out, allowing SCAI tool to be tested and validated in real cases. From the comparison of the theoretical framework established and the analysis of the data obtained, we found that the differences in teaching should be valued and seen as assets by HE institutions rather than annihilated in a globalizing perspective.

A percepção dos trabalhadores da enfermagem acerca da avaliação de desempenho do servidor público

A concepção de avaliação de desempenho dos trabalhadores da enfermagem, na maioria das vezes, é a de um ato de julgamento entre o certo e o errado, relacionado às ações e posturas desenvolvidas no contexto do seu trabalho. A avaliação de desempenho, no entanto, pode ser visualizada pelos trabalhadores como um importante instrumento que favorece o feedback do fazer profissional, desafiando-os a olharem para si mesmos, para o desenvolvimento de suas atribuições profissionais, proporcionando um real entendimento de sua importância na sociedade. Assim tem-se como objetivo geral conhecer a percepção dos trabalhadores da enfermagem de um Hospital Universitário localizado no extremo sul do Rio Grande do Sul (HU) acerca da sistemática da avaliação dos servidores públicos vivenciada na instituição e como objetivo específico conhecer a percepção dos trabalhadores da enfermagem do HU acerca da sistemática da avaliação dos servidores públicos no período do estágio probatório, adotada na instituição. Trata-se de uma pesquisa com abordagem qualitativa do tipo exploratória, desenvolvida com 70 trabalhadores de enfermagem. Para a coleta de dados utilizou-se a técnica de entrevista. Mediante a análise textual discursiva, construíram-se duas categorias: A avaliação do desempenho na concepção de trabalhadores da enfermagem e Serviço público: representatividade para o serviço da enfermagem. A avaliação do desempenho do servidor público pode ser influenciada pelo período de estágio probatório, pela sua vulnerabilidade na instituição, com possibilidade de conquistar a estabilidade ou perdê-la. Decorrido o período probatório, alguns trabalhadores modificam seu comportamento, demonstrando, por vezes, falta de comprometimento com seu fazer. No entanto, tal mudança pode estar relacionada com a cultura organizacional existente na instituição pública e, ainda, com um aparente descontentamento dos trabalhadores na realização da avaliação de desempenho, por não receberem um retorno significativo de cada avaliação. Pensar a sistemática de avaliação de desempenho com os trabalhadores da enfermagem significou a possibilidade de desencadear um processo de discussão e de reflexão sobre os diferentes modos de ser e fazer a enfermagem.

The Impact of a Simulated Clinical Experience on CEGEP Nursing Students’ Perceptions of Self-Efficacy and Achievement

Abstract : Providing high-quality clinical experiences to prepare students for the complexities of the current health-care system has become a challenge for nurse educators. Additionally, there are concerns that the current model of clinical practice is suboptimal. Consequently, nursing programs have explored the partial replacement of traditional in-hospital clinical experiences with a simulated clinical experience. Despite research demonstrating numerous benefits to students following participation in simulation activities, insufficient research conducted within Québec exists to convince the governing bodies (Ordre des infirmières et des infirmiers du Québec, OIIQ; Ministère de L’Éducation supérieur, de la Recherche, de la Science et de la Technologie) to fully embrace simulation as part of nurse training. The purpose of this study was to examine the use of a simulated clinical experience (SCE) as a viable, partial pedagogical substitute for traditional clinical experience by examining the effects of a SCE on CEGEP nursing students’ perceptions of self-efficacy (confidence), and their ability to achieve course objectives. The findings will contribute new information to the current body of research in simulation. The specific case of obstetrical practice was examined. Based on two sections of the Nursing III-Health and Illness (180-30K-AB) course, the sample was comprised of 65 students (thirty-one students from section 0001 and thirty-four students from section 0002) whose mean age was 24.8 years. With two sections of the course available, the opportunity for comparison was possible. A triangulation mixed method design was used. An adapted version of Ravert’s (2004) Nursing Skills for Evaluation tool was utilized to collect data regarding students’ perceptions of confidence related to the nursing skills required for care of mothers and their newborns. Students’ performance and achievement of course objectives was measured through an Objective Structured Clinical Examination (OSCE) consisting of three marked stations designed to test the theoretical and clinical aspects of course content. The OSCE was administered at the end of the semester following completion of the traditional clinical experience. Students’ qualitative comments on the post -test survey, along with journal entries served to support the quantitative scale evaluation. Two of the twelve days (15 hours) allocated for obstetrical clinical experience were replaced by a SCE (17%) over the course of the semester. Students participated in various simulation activities developed to address a range of cognitive, psychomotor and critical thinking skills. Scenarios incorporating the use of human patient simulators, and designed using the Jeffries Framework (2005), exposed students to the care of families and infants during the perinatal period to both reflect and build upon class and course content in achievement of course objectives and program competencies. Active participation in all simulation activities exposed students to Bandura’s four main sources of experience (mastery experiences, vicarious experiences, social persuasion, and physiologic/emotional responses) to enhance the development of students’ self-efficacy. Results of the pre-test and post-test summative scores revealed a statistically significant increase in student confidence in performing skills related to maternal and newborn care (p < .0001) following participation in the SCE. Confidence pre-test and post-test scores were not affected by the students’ section. Skills related to the care of the post-partum mother following vaginal or Caesarean section delivery showed the greatest change in confidence ratings. OSCE results showed a mean total class score (both sections) of 57.4 (70.0 %) with normal distribution. Mean scores were 56.5 (68.9%) for section 0001 and 58.3 (71.1%) for section 0002. Total scores were similar between sections (p =0.342) based on pairwise comparison. Analysis of OSCE scores as compared to students’ final course grade revealed similar distributions. Finally, qualitative analysis identified how students’ perceived the SCE. Students cited gains in knowledge, development of psychomotor skills and improved clinical judgement following participation in simulation activities. These were attributed to the « hands on » practice obtained from working in small groups, a safe and authentic learning environment and one in which students could make mistakes and correct errors as having the greatest impact on learning through simulation.

Performance Energética no contexto do sistema LEED

Com o aumento constante de procura de recursos naturais por parte dos vários setores da sociedade é urgente encontrar soluções para reduzir o seu consumo sem se travar a expansão demográfica que se tem vindo a sentir nos grandes centros urbanos. É através da implementação de medidas de sustentabilidade e pelo aumento da eficiência de utilização desses recursos que se tem vindo a combater esta tendência cada vez maior de consumismo global, sendo isto apenas possível com a implementação de ferramentas tecnológicas avançadas que permitem estabelecer limites ao considerado eficiente e premiando, em termos financeiros e de imagem de marketing, as entidades que o alcancem. O LEED é um sistema de certificação de sustentabilidade voluntário de edifícios residenciais e comerciais que estabelece métricas de comparação de parâmetros indicadores de consumos energéticos, hídricos e de materiais em todo o ciclo de vida do edifício e que tem vindo a ganhar destaque em crescendo a nível mundial. Esta dissertação teve como objetivo comparar a performance de consumo energético no âmbito do sistema LEED com a do sistema de certificação energética de edifícios nacional (SCE) de um grande edifício de serviços, estabelecendo um paralelismo de semelhanças e diferenças entre os dois e de avaliar os efeitos de potenciais medidas de eficiência energética e seus efeitos nas classificações de mérito obtidas em cada sistema. Os resultados obtidos na simulação que permitiu avaliar a performance foi muito satisfatório, tendo sido aproveitado pela empresa para efeitos de certificação LEED do edifício em estudo.

Avaliação da performance do árbitro de futebol 11 : estudo de caso

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.

Team performance according to ball possession characteristics : a social networks approach

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.

Avaliação de desempenho : estudo de caso da aplicação do balanced scorecard numa organização especializada na área do exercício, saúde e bem-estar

Atividade física, saúde e bem-estar são temas presentes no dia-a-dia das pessoas. O mercado do Fitness está dinâmico e ativo, quer na comunicação, através das novas tecnologias de informação, quer na especialização da oferta de produtos ou serviços. O Personal training surge como um produto feito á medida do cliente, importante numa sociedade onde a individualidade sobressai, as preferências e necessidades divergem de cliente para cliente. É solicitada uma boa performance constantemente ao profissional, que se pretende traduzida em altas taxas de angariação e retenção. O Balanced Scorecard (BSC), apresenta soluções válidas neste contexto de mercado, já que é uma ferramenta de apoio á gestão estratégica e simultaneamente um sistema de monitorização em tempo real dos indicadores de performance dos profissionais (Personal Trainer) e dos restantes níveis hierárquicos da Organização. Num mercado concorrencial, a valorização do recurso humano tem-se revelado crucial nos resultados alcançados e principal fator de criação de valor e vantagem competitiva, quando bem monitorizada e orientada pela Gestão da Organização. Surge como desafio maior, elaborar, posicionar, implementar, avaliar e medir através deste instrumento (BSC), num contexto laboral diferente (prestadores de serviços) onde já foi aplicado e apurar o nível de desempenho alcançado pela organização orientado nas respetivas visões: financeira, clientes, aprendizagem – crescimento e processos internos.

On the Bleeding Edge : Debloating Internet Access Networks

As ever more devices are connected to the internet, and applications turn ever more interactive, it becomes more important that the network can be counted on to respond reliably and without unnecessary delay. However, this is far from always the case today, as there can be many potential sources of unnecessary delay. In this thesis we focus on one of them: Excess queueing delay in network routers along the path, also known as bufferbloat. We focus on the home network, and treat the issue in three stages. We examine latency variation and queueing delay on the public internet and show that significant excess delay is often present. Then, we evaluate several modern AQM algorithms and packet schedulers in a residential setting, and show that modern AQMs can almost entirely eliminate bufferbloat and extra queueing latency for wired connections, but that they are not as effective for WiFi links. Finally, we go on to design and implement a solution for bufferbloat at the WiFi link, and also design a workable scheduler-based solution for realising airtime fairness in WiFi. Also included in this thesis is a description of Flent, a measurement tool used to perform most of the experiments in the other papers, and also used widely in the bufferbloat community.

The conditional performance of euro bond funds: evidence from Portugal during the debt crisis

This paper evaluates the performance of a survivorship bias-free data set of Portuguese funds investing in Euro-denominated bonds by using conditional models that consider the public information available to investors when the returns are generated. We find that bond funds underperform the market significantly and by an economically relevant magnitude. This underperformance cannot be explained by the expenses they charge. Our findings support the use of conditional performance evaluation models, since we find strong evidence of both time-varying risk and performance, dependent on the slope of the term structure and the inverse relative wealth variables. We also show that survivorship bias has a significant impact on performance estimates. Furthermore, during the European debt crisis, bond fund managers performed significantly better than in non-crisis periods and were able to achieve neutral performance. This improved performance throughout the crisis seems to be related to changes in funds’ investment styles.
