Abstract The main purpose of this thesis is to analyse websites and Facebook profiles of chosen brands of Nestlé company and their competition. This thesis is divided into two parts - theoretical and practical. The theoretical part deals with basics of methodology of evaluating websites and Facebook profiles and consists of following parts: graphics and design of websites, visibility on the internet, SEO, information, technical solutions, applicabillity, accessibility and Facebook. All these parts are essential for assessment methodology. The practical part contains the assessment itself according to created methodology. Eleven selected websites and facebook profiles are assessed here. Furthemore, all results are summerized in this part and conclusions as well as recommendatins are drawn from them. The main contribution of this diploma thesis is a comprehensive comparison of selected websites and Facebook profiles of Nestlé company and recommendations made on the basis of the comparison.

The Internet has changed the way society communicates with one another. One of the organizations that utilize the Internet in order to communicate with their audience is universities. The imagery and information that is featured in the homepages of university websites can portray a certain perception of that university. Universities were found to be diverse in the ethnic background of the persons used for their homepage imagery. The way minority characters were found to be portrayed in gave a general idea of what exist within academia as to how they view and portray minority groups.

Internet has emerged as an interactive platform. Thus, new communication technologies are challenging the traditional media with interactive devices turning online journalism into a rich media environment. While new information technologies have enabled media organisations to use interactive features in the constructed presentation of news websites, few news websites in the Iraqi Kurdistan region are maximizing such features. Also, this thesis argues that despite the lack of a good infrastructure in the field of communication technology and the Internet in the Iraqi Kurdistan Region (IKR), online journalism has become a major part of Kurdish media outlets and distinctive from traditional media because of its interactive nature. The study presented in this thesis focus on interactivity in online journalism by examine interactive features of Kurdish news websites of the (IKR) and analyses how news is presented and to what extent these news websites tried to apply the interactive features on their hompages and inside the news pages. The level of interactivity of those Kurdish websites was also measured using several dimensions of interactivity by conducting web-based content analysis. The analysis of the qualitative part based on in-depth interviews with Kurdish reporters, editors, editor in chiefs, media experts and web developers. The findings show that the Kurdish news websites did not fully utilize and enhance interactive features in online journalism.

No / This paper investigates into the performance and load management of web servers that are deployed in commercial websites. Such websites offer various services such as flight/hotel booking, online banking, stock trading, and product purchases among others. Customers are increasingly relying on these round-the-clock services which are easier and (generally) cheaper to order. However, such an increasing number of customers' requests makes a greater demand on the web servers. This leads to web servers' overload and the consequential provisioning of inadequate level of service. This paper addresses these issues and proposes an admission control scheme which is based on the class-based priority scheme that classifies customer's requests into different classes. The proposed scheme is formally specified using -calculus and is implemented as a Java-based prototype system. The prototype system is used to simulate the behaviour of commercial website servers and to evaluate their performance in terms of response time, throughput, arrival rate, and the percentage of dropped requests. Experimental results demonstrate that the proposed scheme significantly improves the performance of high priority requests but without causing adverse effects on low priority requests.

The A/E/C industry faces the inability to meet client demands of projects completed on time and on schedule due to the minimal collaboration between parties, communication problems, and mistakes. The present project management system in the industry is paper-based, and requires the owners of information to distribute the knowledge at their discretion. This system has inherent delays in information transmission, which lead to miscommunications, mistakes, and costly rework, which in turn, cause increases in the project schedule and budget. There is a need to fundamentally change the project management philosophy of the industry. Rather than each party maintaining a project management system, there needs to be a single, integrated project-based system. One type of integrated project management systems is project-specific websites. This research focuses specifically on the project-specific websites for project management (PSWS) offered by construction-based project management application service providers (PMASPs). While there are substantial improvements in the project process including cost and time savings by using a PSWS, the industry is reluctant to adopt the new technology. There are numerous barriers to the implementation of PSWS. A large barrier is determining how to implement and use PMASP-Based PSWS. Through a literature review, a project management questionnaire, investigations of the leading construction-based project management application service providers (PMASPs), and implementation case studies, a chapter on implementation considerations and lessons was developed. The Implementation Considerations and Lessons chapter serves to provide companies a basis for PSWS implementation and use. The chapter contains three parts: background, implementation, and sustainability. The background section identifies the benefits of using PSWS, examines the ability of five construction-based project management application service providers to meet the project management need of the parties, and identifies the barriers to implementation users should expect. The second part of the chapter details the steps needed to successfully implement and use the system. The final part describes the sustainability challenges that occur after implementation. / Master of Science

The aim of this study is to seek fundamental uses and gratifications of a social networking website, Facebook as a case, and the possible advantages and the challenges of utilization of Facebook for instructional activities. The research study encompassed four main steps / the analysis of uses &amp / gratifications of Facebook, the analysis of Facebook utilization possibilities for instruction, the interviewing for two preceding steps, and the realization and analysis of a course on Facebook. In the study both qualitative and quantitative data were gathered through questionnaires, interviews and open-ended questions. The qualitative data was analyzed according to qualitative data analysis techniques and quantitative data was analyzed using SPSS software. The results showed that Facebook which is perceived as a usable tool has a potential utilization for instructional activities. As quite new context, the participants seemed concerned about participating any learning activity on Facebook. Most of the participants in all steps of the study emphasized that Facebook should be a supplementary material for instructional activities. It is concluded that individual differences and alternative methods must be studied for better integration of Facebook into education.

O presente trabalho analisa as metodologias de projeto de arquitetura de informação de websites sob o foco das abordagens de Design Centrado no Usuário da Ciência da Informação e da Interação Humano-Computador. A metodologia adotada foi uma revisão da literatura, para formular um quadro de referência para análise das metodologias de projetos de arquitetura de informação, e duas pesquisas de campo. A primeira pesquisa foi quantitativa, baseada em um questionário on-line, e teve por objetivo levantar o perfil do arquiteto de informação das listas de discussões brasileiras. A segunda pesquisa foi qualitativa e seguiu a abordagem do Sense-making, tendo como objetivo levantar as dificuldades, técnicas e metodologias encontradas nos projetos de arquitetura de informação de websites. Como resultado da revisão da literatura foi formulado um quadro de referência composto de cinco fases (Pesquisa, Concepção, Especificação, Implementação e Avaliação). Os princípios das abordagens de Design Centrado no Usuário são aplicados nas duas fases iniciais, sendo que na primeira é aplicada a abordagem da Ciência da Informação, e na segunda a abordagem da Interação Humano-Computador. A primeira pesquisa de campo retratou um profissional jovem, que vive nos grandes centros metropolitanos, com formação predominante na área de Humanas e que desenvolveu seus conhecimentos sobre Arquitetura de Informação de maneira autodidata. Quase metade deles não segue qualquer metodologia nos seus projetos e, entre os que seguem, a maioria utiliza uma metodologia própria. A segunda pesquisa mostrou que os arquitetos de informação experientes adotam uma metodologia nos seus projetos e dedicam mais atenção às três primeiras fases do quadro de referência (Pesquisa, Concepção e Especificação). As metodologias vistas na prática não seguem a abordagem de Design Centrado no Usuário da Ciência da Informação, pois raramente são feitas pesquisas com usuários. Com relação à abordagem da Interação Humano-Computador, ela é pouco seguida porque os contratantes desconhecem a importância dos testes de usabilidade e porque os arquitetos não dominam as técnicas desses testes mais adequadas à Arquitetura de Informação. Com relação às dificuldades enfrentadas nos projetos, foram identificados três focos: o contratante, o próprio trabalho de Arquitetura de Informação e o contexto tecnológico em que o website está inserido, sendo o primeiro o mais citado. Conclui-se que as metodologias de projetos de arquitetura de informação precisam evoluir na adoção das abordagens de Design Centrado no Usuário, para que consigam produzir websites que satisfaçam plenamente as necessidades dos usuários, e nas formas de avaliar os resultados, para verificar se os objetivos dos projetos foram plenamente alcançados. / The study analyzes information architecture projects methodologies of websites under the focus of User Centered Design approaches of Information Science and Human-Computer Interaction. The adopted methodology included a literature review, to formulate a theoric model to analyze information architecture project methodologies, and two empirical researches. The first one was a quantitative research, based on an on-line questionnaire which aimed at mapping the profile of information architects in Brazilian discussion lists. The second one was a qualitative research, in which the Sense-making approach was applied to map the difficulties, techniques and methodologies found in information architecture projects of websites. As result the revision of literature review a theoric model with five phases was formulated (Research, Conception, Specification, Implementation and Evaluation) in which the approaches of User Centered Design should be applied in the two initial phases, in the first one should be applied the approach of Information Science and in the second one the approach of Human-Computer Interaction. The first research showed a young professional, that lives in the great metropolitan centers, which is often graduated in Human area and developed their knowledge of Information Architecture in an autodidactic way. Almost half of them doesn\'t follow any methodology in their projects and, most of the ones that follow uses theirs own methodology. The second research showed that seniors information architects adopt a methodology in theirs project and they dedicate more attention to the first three phases of the theoric model (Research, Conception and Specification). The methodologies found in practice don\'t follow the User Centered Design approach of Information Science, because they rarely make researches with users. The Human-Computer Interaction approach is little following because the clients are not convinced of the importance of usability tests and because information architects don\'t really know the techniques of usability tests more appropriate to information architecture projects. It were identified three focuses of difficulties faced in the projects: the clients, the own work of Information Architecture and the technology context in that the websites is inserted. It concludes that the methodologies of information architecture projects need to increase in the adoption of User Centered Design, to produce websites that fully satisfy the users, and in ways to evaluate the results of the projects, to verify if its objectives had been reached.
