No / We examine the effect of family governance on corporate philanthropy by focusing on the motives of controlling families. We emphasize that controlling families have two different motives, namely, financial and socioemotional motives. On this basis, we argue that the two motives have contrasting effects on corporate philanthropy. Given that family ownership represents the financial motive of family principals, the first hypothesis posits that family ownership is negatively related to corporate philanthropy. Family management increases family visibility and thus encourages controlling families to be concerned with their socioemotional wealth. That is, the higher the visibility of controlling families in the firm, the more likely the overlap will be between family and firm identity. Thus, the second and third hypotheses predict that family involvement in management as a family CEO or director positively moderates the relationship between family ownership and corporate philanthropy. We test our hypotheses using fixed effects panel regression models and the sample of large nonfinancial Korean family firms listed in KOSPI, Korea’s major stock market. Test results support our hypotheses. We find that family firms become reluctant to engage in discretionary wealth transfer to nonfamily stakeholders as family ownership increases. However, this negative effect of family ownership on corporate philanthropy is weakened by family involvement in top management and the board of directors. Our findings reconcile the inconsistent results in the literature on family business and CSR, which is divided into positive and negative perspectives. In this manner, we revisit the assumption of prior research, which often treats family firms as homogeneous and reveals the limitation of a dichotomous approach to family business. We conclude by discussing the implications and theoretical contributions of this study and offering future research directions.

Recent research has indicated that although security systems are developing, illegal intrusion to computers is on the rise. The research conducted here illustrates that improving intrusion detection and prevention methods is fundamental for improving the overall security of systems. This research includes the design of a novel Intrusion Detection System (IDS) which identifies four levels of visibility of attacks. Two major areas of security concern were identified: speed and volume of attacks; and complexity of multistage attacks. Hence, the Multistage Intrusion Detection and Prevention System (MIDaPS) that is designed here is made of two fundamental elements: a multistage attack engine that heavily depends on attack trees and a Denial of Service Engine. MIDaPS were tested and found to improve current intrusion detection and processing performances. After an intensive literature review, over 25 GB of data was collected on honeynets. This was then used to analyse the complexity of attacks in a series of experiments. Statistical and analytic methods were used to design the novel MIDaPS. Key findings indicate that an attack needs to be protected at 4 different levels. Hence, MIDaPS is built with 4 levels of protection. As, recent attack vectors use legitimate actions, MIDaPS uses a novel approach of attack trees to trace the attacker's actions. MIDaPS was tested and results suggest an improvement to current system performance by 84% whilst detecting DDOS attacks within 10 minutes.

La synthèse d'images, qui consiste à développer des algorithmes pour générer des images à l'aide d'un ordinateur, est devenue incontournable dans de nombreuses disciplines. Les méthodes d'affichage interactives permettent à l'utilisateur d'explorer des environnements virtuels en réalisant l'affichage des images à une cadence suffisamment élevée pour donner une impression de continuité et d'immersion. Malgré les progrès réalisés par le matériel, de nouveaux besoins supplantent toujours les capacités de traitement, et des techniques d'accélération sont nécessaires pour parvenir à maintenir une cadence d'affichage suffisante. Ce travail s'inscrit précisemment dans ce cadre. Il est consacré à la problématique de l'élimination efficace des objets masqués, en vue d'accélérer l'affichage de scènes complexes. Nous nous sommes plus particulièrement intéressé aux méthodes de précalcul, qui effectuent les calculs coûteux de visibilité durant une phase de prétraitement et les réutilisent lors de la phase de navigation interactive. Les méthodes permettant un précalcul complet et exact sont encore hors de portée à l'heure actuelle, c'est pourquoi des techniques approchées leur sont préférée en pratique. Nous proposons trois méthodes de ce type. La première, présentée dans le chapitre 4, est un algorithme permettant de déterminer de manière exacte si deux polygones convexes sont mutuellement visibles, lorsque des écrans sont placés entre eux. Nos contributions principales ont été de simplifier cette requête, tant du point de vue théorique que du point de vue de l'implémentation, ainsi que d'accélérer son temps moyen d'exécution à l'aide d'un ensemble de techniques d'optimisation. Il en résulte un algorithme considérablement plus simple à mettre en oeuvre que les algorithmes exacts existant dans la littérature. Nous montrons qu'il est également beaucoup plus efficace que ces derniers en termes de temps de calcul. La seconde méthode, présentée dans le chapitre 5, est une approche originale pour encoder l'information de visibilité, qui consiste à stocker l'ombre que générerait chaque objet de la scène s'il était remplacé par une source lumineuse. Nous présentons une analyse des avantages et des inconvénients de cette nouvelle représentation. Finalement, nous proposons dans le chapitre 6 une méthode de calcul de visibilité adaptée aux scènes d'intérieur. Dans ce type d'environnements, les graphes cellules-portails sont très répandus pour l'élimination des objets masqués, en raison de leur faible coût mémoire et de leur grande efficacité. Nous reformulons le problème de la génération de ces graphes en termes de segmentation d'images, et adaptons un algorithme classique, appelé «watershed», pour les obtenir de manière automatique. Nous montrons que la décomposition calculée de la sorte est proche de la décomposition classique, et qu'elle peut être utilisée pour l'élimination des objets masqués.

I denna studie undersöks och analyseras kopplingen mellan yrkesutbildningens mål och APL för att få en rättssäker och likvärdig betygsättning. Jag har undersökt sex yrkeslärare inom gymnasial yrkesutbildning på handels- och administrationsprogram om deras bedömningspraktik i samband med det arbetsplatsförlagda lärandet (APL). Jag har även undersökt åtta elever på handels- och administrationsprogrammet om hur de uppfattar kursmål/bedömningar /uppföljning under sin APL-period. Datainsamlingen har skett genom kvantitativa enkät-undersökningar. Det insamlade materialet sammanställdes och därefter analyserades data i förhållande till studiens frågeställningar. Den teoretiska utgångspunkten fokuserar på bedömningspraktiken, uppföljning/återkoppling samt kommunikationens betydelse för lärandet och bedömning. Tidigare forskning visar att en tydlig bedömningspraktik är mycket viktig för att få en så bra koppling mellan skolans mål och APL-platsen som möjligt. Resultatet visar att de flesta har en väl fungerande bedömningspraktik. Flera yrkeslärare säger dock att tiden är det största hindret för rättssäker och likvärdig betygssättning. Rektorn har i detta sammanhang en central roll i att organisera verksamheten så att förutsättningar ges för detta arbete. / This stydy investigates and analyses the connection between the vocational educations aim and APL to get an assured and equivalent assessment. I have surveyed six vocational education teachers within secondary vocational education in business and administration programme about their assessment practice in connection with the workplace-based learning (APL). I have moreover surveyed eigth students in business and administration programme about how they perceived the course objective/ assessment/ monitoring during their APL-period. The data collection has been carried out in the form of quantitative questionnaires. The gathered data got compiled and subsequently analysed in relation to the studies question formulations. The theoretical premiss focuses on the assessment practice, monitoring/ feedback and the communications significance for the learning and assessment. Prior research shows a clear assessment practice is quite important to get as good of a connection between the schools aim and the APL-place as possible. The result shows that most have a well functioning assessment practice. Several vocational education teachers says however that time is the biggest hindrance for an assured assessment practice. The principal has in this contexture a central role in organizing the schools activity so that the basis is given for this work.

La mesure de la visibilité météorologique est un élément important pour la sécurité des transports routiers et aériens. Nous proposons dans ce travail de recherche un indicateur de la visibilité météorologique adapté aux caméras fixes de vidéo surveillance du réseau routier. Il est fondé sur le module du gradient sélectionné dans des zones dont le comportement suit une loi de réflexion de Lambert vis à vis des conditions d'éclairage. La réponse de cet indicateur est issue d'une modélisation fondée sur une hypothèse de la distribution des profondeurs dans la scène. Celle-ci est calibrée avec des données provenant d'un visibilimètre ou bien avec une carte de profondeurs issue d'un modèle numérique de terrain. Les estimations sont ensuite comparées avec des données de référence obtenues par un visibilimètre et montrent une erreur moyenne similaire pour des images prises dans différentes conditions d'éclairage et de visibilité météorologique / The measurement of the meteorological visibility is an important element for the safety of road and air transport. We propose in this thesis a meteorological visibility indicator adapted to video surveillance cameras of the road network. This descriptor is based on the module of the gradient selected in areas that follow Lambert's reflection law. The response of this descriptor is derived from a model based on the statistical distribution of depth in the scene. Calibration is performed with data from a visibilimeter, or with a depth map from a digital terrainmodel. The results are then compared with reference data obtained from a visibilimeter and show a similar mean error for images taken in different illumination and meteorological visibility conditions

Essa tese de doutoramento trata principalmente dos estudos sobre a formação do registro arqueológico relacionado ao contexto afrodiaspórico da comunidade remanescente de Quilombo do Boqueirão, no município de Vila Bela, Mato Grosso, região do Alto Vale do Guaporé. Os dados analisados na investigação começaram a ser levantados em 2008 durante o mestrado e abordam aspectos do modo de vida e da transformação da materialidade quilombola, sob a perspectiva da arqueologia do presente. O objetivo central da análise foi discutir (e promover) aspectos da visibilidade arqueológica e social deste coletivo, por meio da prática colaborativa que possibilitou a investigação em três contextos distintos: um sítio arqueológico, dois sítios de abandono recente e dois sítios do presente. Essa tese é também o resultado de múltiplas vozes que que atuaram no desenvolvimento da pesquisa ao longo dos anos e como tal, sua escrita primou por conciliar a escrita acadêmica com uma forma simples, direta e imagética de dialogar os interlocutores, colaboradores e amigos do Boqueirão. / This doctoral thesis consists of studies on the formation of the archaeological record related to the afro-diasporic context of the remaining community of Quilombo do Boqueirão, municipality of Vila Bela, Mato Grosso, Alto Vale do Guaporé region. The data is an investigation initiated in 2008 over a period of one year and addresses aspects of the way of life and transformation of materiality from an archeology perspective. The main analysis site has been published and is available for publication in three distinct contexts: an archaeological site, two sites of recent abandonment and two sites. This is that or is it an action, which writing the knowledge has not interest the media and academic language students, the word to the interest of the academic students, and was of the Boqueirão.

A sequência de protestos em junho de 2013 sacudiu o cenário político brasileiro como um terremoto - foram manifestações que começavam e terminavam nas telas. Além de matéria-prima para imagens, as passeatas também como imagens sociais (dependem do olhar social) e itinerantes (para adquirir valor e significado), fundando uma nova visibilidade. Para apreender a dimensão desses eventos na instância da imagem ao vivo, foi analisada a edição especial do Jornal Nacional do dia 20 de junho daquele ano. Nos resultados, obtidos por meio da técnica da análise de conteúdo, é notório o adestramento do olhar que, insensível, olhou a multidão de uma perspectiva superior. / The series of protests in June 2013 has changed Brazilian political scenery in an abrupt way as an earthquake - the demonstrations began and ended on the television screens. More than base for images, the riots constitute social images (which depend on the social point of view) and are itinerant (to form value and meaning). To comprehend the dimension of these events in the context of instance of the live image, this work studies, by content analyses approach, the special edition of Jornal Nacional in the 20th June 2013. The results show that the point of view of the imagetic speech is cold, unsympathetic and arrogant towards the protesters.

A qualidade dos sistemas de sinalização viária é avaliada, tradicionalmente, com base nas características físicas de seus elementos, bem como na durabilidade e conservação dos materiais que os compõem. Em alguns casos, a verificação do atendimento aos critérios técnicos de projeto é também considerada. Depreende-se, daí, que a avaliação estrutural dos elementos de sinalização seja integralmente contemplada por meio dessas avaliações. Por outro lado, a eficácia da sinalização não é necessariamente garantida pela integridade física ou estrutural dos elementos. Por se tratar de um sistema de comunicação com o usuário, que transmite informações que influenciarão as ações dos motoristas na tarefa de guiar o veículo no trânsito, é necessário, também, avaliar o desempenho funcional dos elementos de sinalização. Em outras palavras, o funcionamento e a eficiência da sinalização são tão importantes quanto a situação de seu estado físico. Esta pesquisa descreve aspectos a serem considerados na avaliação de desempenho funcional dos sinais de trânsito com base na observação no campo e na abordagem dos fatores que afetam as medidas de desempenho, conduzindo, em rodovias federais brasileiras concedidas à iniciativa privada, dois experimentos ainda pouco conhecidos no país. O primeiro experimento avaliou o desempenho de um conjunto de placas de sinalização de regulamentação de velocidade máxima permitida, aplicadas em configurações diversas. As medidas de desempenho escolhidas foram a distância de detecção e a distância de legibilidade da sinalização, que foram medidas por meio de observadores em curso na rodovia, em condições reais de operação. O segundo experimento avaliou o desempenho de um conjunto de demarcações no pavimento de uma rodovia também em condições reais de operação. A medida de desempenho foi a retorrefletividade da sinalização horizontal sob tráfego real. A pesquisa inova ao utilizar o conceito de planejamento de experimentos, otimizando o modelo estatístico a ser estimado com menos execuções experimentais. / The quality of the traffic signs systems is traditionally assessed based on physical characteristics of their elements, as well as the durability and conservation of materials they are made of. In some cases, the verification of compliance with the technical criteria for design is also considered. Therefore, it appears that the structural assessment of sign elements is fully covered by these evaluations. Moreover, the effectiveness of traffic signs is not necessarily guaranteed by physical or structural health of the elements. Once the traffic signs comprise a system of communication with the users, which gives information that will influence the actions of the drivers on the task of guiding the vehicle in traffic flow, it is also necessary to evaluate the functional performance of the traffic signs. In other words, the operation and efficiency of traffic signs are as important as their physical condition. This research describes some aspects to take into account in the evaluation of performance of traffic signs based on observation in the field and in the approach of the factors affecting performance measures, carrying out in Brazilian federal highways under concession to the private sector two experiments still little known in this country. The first experiment evaluated the performance of a set of speed limit signs applied in different configurations. The chosen performance measures were the detection distance and the legibility distance of the signs, which were measured by subjects driving on open road under real operating conditions. The second experiment evaluated the performance of a set of pavement markings also on open road under real operating conditions. The performance measure was the retroreflectivity of the pavement markings under real traffic. The survey breaks new ground by using the concept of optimal design of experiments, optimizing the statistical model to be estimated with fewer experimental runs.

The theoretical framework covers the conceptual field of communication, consumption, citizenship, image, visualities and migrations transnational corporations. The methodology of the research is based on bibliographic research and documentary; observation of production spaces and reception of the photographic exhibition; collection and exposure image analysis; interviews with producers and the immigrant public and not immigrant. The results of the research point to three main dimensions that resulting from the processes of production of the appropriations of the photographic exposure: (1) the recognition of a dominant media visibility that hierarchizes the immigrants and associates them with problem, conflict, poverty; (2) the possibilities of setting up other citizen visions, especially those that uniquely distinguish, without folklore, and favor a humanizing approach with the immigrant Other; and (3) the limits imposed other visibilities in the field of migration that the need for public policies that assure immigrants access to and occupation of both from the media and from the city . / Esta pesquisa analisa as relações entre comunicação, consumo e migrações a partir do estudo dos processos de produção e recepção da exposição fotográfica "Somos Todos Imigrantes", buscando compreender os enquadramentos e percepções em torno da visibilidade midiática e pública dos imigrantes transnacionais na cidade de São Paulo. O referencial teórico abrange o campo conceitual da comunicação, consumo, cidadania, imagem, visualidades e migrações transnacionais. A metodologia da pesquisa fundamenta-se em pesquisa bibliográfica e documental; observação de espaços de produção e recepção da mostra fotográfica; coleta e análise das imagens da exposição; entrevistas com os produtores e com o público imigrante e não imigrante. Os resultados da pesquisa apontam para três dimensões principais que resultam dos processos de produção de das apropriações das imagens fotográficas da exposição: (1) o reconhecimento de uma visibilidade midiática dominante que hierarquiza os imigrantes e os associa a problema, conflito, pobreza; (2) as possibilidades de constituição de outras visibilidades cidadãs, especialmente aquelas que singularizam, sem folclorizar, e favorecem uma aproximação humanizadora com o Outro imigrante; e (3) os limites impostos à produção dessas outras visibilidades no campo das migrações que aparecem associados à necessidade de políticas públicas que assegurem aos imigrantes acesso e ocupação de espaços tanto da mídia quando da cidade.

The Afro-Brazilian religious universe in Maringá is, still today, little known by most people. Our interest, in this study, is to reveal it through the shrines active in the city, their origins, filiations (lineage), their priests and followers, how they face prejudice that is, in fact, still very strong, and the relations between shrine groups and society. Revealing the presence of those religions, the study seeks to contribute not only to the knowledge of the origins and path of the Afro-Brazilian religions in Maringá, but also of their capability of resistance and affirmation in a notoriously adverse religious scene / A pesquisa "Maringá de todos os santos: presença das religiões afrobrasileiras" busca, a partir da observação da negação da presença negra em Maringá, revelar tal presença, escondida que está em suas expressões religiosas. O universo religioso afro-brasileiro em Maringá ainda hoje é pouco conhecido pela maior parte das pessoas. Nosso interesse nesta pesquisa é revelá-lo através dos terreiros atuantes na cidade, suas origens, suas filiações (linhagem), seus sacerdotes e adeptos, como eles (elas) encaram o preconceito, que, de fato, ainda é muito forte, e as relações entre os terreiros e a sociedade. Ao revelar a presença destas religiões, a pesquisa busca contribuir para o conhecimento não só das origens e a trajetória das religiões afro-brasileiras em Maringá, mas também da sua capacidade de resistência e afirmação num campo religioso francamente adverso
