”Spelen är ju typ alltid på engelska…” : Elevers medvetenhet om MMO-spels påverkan på engelskkunskaper / ”The games are always in English…” : Pupils’ awareness of the influence of MMO-games on English language skills – a qualitative studyBergstrand, Isak January 2017 (has links)
Syftet med studien är att undersöka elevers uppfattningar om Massive Multiplayer Online-spels (MMO-spel) inverkan på engelskkunskaper. Studien, likt tidigare forskning inom om-rådet, grundar sig i ett sociokulturellt perspektiv. En kvalitativ metod i form av semistruk-turerade intervjuer har använts för att intervjua deltagare i årskurs 6. Följande frågeställ-ningar har legat som grund för studien: Hur beskriver elever sitt eget och klasskamraters spelande av MMO-spel i förhållande till engelskinlärning? Hur beskriver elever att de och andra lär sig engelska i MMO-spel? Hur ser elever på MMO-spel som ett möjligt verktyg för språkinlärning i engelskundervisning?Intervjuerna analyserades med en fenomenografiskt inspirerad modell i sju steg för att få fram ett resultat. Resultatet visar att eleverna är medvetna om MMO-spels inverkan på eng-elskkunskaper. Medvetenheten hos deltagarna berör inte enbart utvecklingen av engelsk-kunskaper utan även spelvanor och vad i spelen det är som utvecklar engelska. Resultatet visar även att eleverna påstår att det är den sociala sidan i spelen som utvecklar och inte själva spelandet. Flertalet av deltagarna är skeptiska till en potentiell användning av MMO-spel i engelskundervisningen. / The purpose of this study is to inquire into the perceptions of the influence which Massive Multiplayer Online games (MMOs) have on the English language skills of those who play them. This study, like other studies in the same field, departs from a sociocultural perspec-tive. This qualitative study employed semi-structured interviews with participants aged be-tween 12 and 13. The study asked the following questions: How do participants perceive the influence MMOs have on their own and others’ English? How do participants describe the experience of learning English through MMOs? How do participants regard the idea of using MMOs as a tool for English language teaching in a formal educational setting?The interviews were analysed with a fenomenographically inspired model to find a result. The results indicate that participants are aware of the impact MMOs have on their English language skills. This awareness encompassed not only the improvement of English lan-guage skills, but also an awareness of their gaming habits and how they also improve English language skills. Furthermore, participants perceived that it is the social aspect of MMOs which improves English skills, as opposed to the game play mechanics. The majority of the participants are, however, skeptical of the use of MMOs in formal English education.

Um serviço de autorização Java EE baseado em certificados de atributos X.509. / A Java EE authorization service based on X.509 attribute certificates.Guilhen, Stefan Neusatz 03 June 2008 (has links)
O surgimento e a popularização de arquiteturas de software que fornecem suporte à programação distribuída orientada a objetos, como CORBA, .NET e Java EE, gerou uma demanda por infra-estruturas de segurança eficientes, capazes de proteger os recursos dos sistemas de ataques maliciosos. Essa proteção começa pela identificação dos usuários que interagem com os sistemas, processo conhecido como autenticação. Entretanto, a autenticação por si só não é suficiente para garantir a segurança dos recursos, uma vez que a autenticação não determina quais ações os usuários estão autorizados a executar depois de autenticados. Em outras palavras, um mecanismo de autorização, que faz valer as políticas de controle de acesso aos recursos definidas pelos administradores de sistemas, se faz necessário. Neste trabalho estudamos mecanismos de controle de acesso baseado em papéis e a aplicabilidade dos certificados de atributos X.509 como estrutura de armazenamento desses papéis em um ambiente Java EE. Em particular, estendemos a infra-estrutura de segurança do servidor de aplicações JBoss, de modo que ela passasse a comportar os certificados de atributos X.509. Além disso, analisamos as vantagens e desvantagens do uso de tais certificados e avaliamos o desempenho da extensão desenvolvida em relação a outras alternativas que são oferecidas pelo JBoss para o armazenamento de papéis dos usuários. / The popularization of software architectures that provide support for distributed object-oriented programming, like CORBA, .NET, and Java EE, revealed the need for efficient security infrastructures to protect the resources of enterprise systems from malicious attacks. This protection usually begins with the identification of the users that interact with the systems, a process known as authentication. However, authentication alone is not enough to guarantee the protection of the resources, as it cannot determine what actions a particular user is allowed to execute on a given resource. In other words, an authorization mechanism is needed in order to enforce the access control policies as defined by the system administrators. In this dissertation we studied role-based access control mechanisms and the use of X.509 attribute certificates as data structures that store the users roles in a Java EE environment. Particularly, we added X.509 attribute certificates support to the existing JBoss application server security infrastructure. Furthermore, we evaluated the pros and cons of using these certificates, and compared the performance of the developed extension to the performance of the existing solutions provided by JBoss to store the users roles.

Inclusion of environmental education in South Korean schoolsGovender, Kanniammah 06 1900 (has links)
The main objectives of this research were to determine the perspectives of South Korean educators regarding the inclusion of environmental education into the curriculum of South Korean schools and to establish the educators’ level of knowledge of environmental education. The research was conducted using a translated questionnaire, which was administered to the educators. The findings of the research showed that few South Korean educators have had any training in environmental education. While most have had no exposure to environmental education it was found that they would appreciate training in the subject. The study highlights the importance of, and discusses the implementation of, environmental education in some Asian countries, as well as the constraints experienced during implementation. On the basis of the research findings, it is recommended that South Korea draw on the knowledge of other countries in both improving the current curriculum so as to include environmental education at all levels, and in the professional development of its educators, in order to bring about the effective inclusion and implementation of environmental education in South Korean schools. / Educational Studies / M.

Investigation and evaluation of high-rise buildings in IDA ICE : A comparative study of energy efficient residential high-rise buildings in different climatesHasselrot, Rasmus January 2015 (has links)
This thesis is part of the major EU project EE-Highrise. The main objective of the EU project is to investigate high-rise buildings in different climates considering energy use, sustainability and cultural and economic differences in different countries. A demo high-rise building has been built in the capital of Slovenia. The purpose of this thesis was to build a model of the demo building in the simulation program IDA Indoor Climate and Environment. The model’s energy performance was then to be simulated in three different regions: Scandinavia, Central Europe and in the Mediterranean. Improvements to the climate shell and the ventilation system were to be examined and the results were then to be compared to European and Swedish Passive House certification schemes. A model was built in the simulation program IDA Indoor Climate and Environment according to the provided drawings of the demo building in Slovenia. Most of the building’s parameters were provided by the project group in Slovenia. When specific parameters were missing or difficult to motivate, standardized values were assumed. The model was modified into five cases: the base case, increased insulation of the external walls, improved glazing and frames for the windows, increased effective heat recovery efficiency and a combination of the energy saving measures. The model’s energy performance was then simulated at five different locations: Naples in Italy, Ljubljana in Slovenia, Malmo in southern Sweden, Karlstad in the middle of Sweden and Kiruna in the northern Sweden. When comparing the results to the requirements for the European Passive House certification, none of the investigated cases met the requirements due to a too large primary energy demand. However, if the requirement regarding the primary energy demand were to be disregarded, then the building in Slovenia would pass the requirements with an increased effective heat recovery efficiency for the ventilation system. Also the building in southern Sweden would pass the requirements with a combination of increased insulation for the external walls, improved windows and increased effective heat recovery efficiency. The Swedish Passive House certification would be fulfilled for the models in Malmo and Karlstad with an increased effective heat recovery efficiency, while the model in Kiruna did not pass the requirements. However, with a combination of the energy saving measures the model in Kiruna came very close to meeting the requirements. The conclusion was that an increased effective heat recovery efficiency had the largest impact on the building’s space heating demand and that improving the windows increased the cooling demand in Naples by a large amount.
