Over the span of the last 16 years of my teaching career I have taught elementary, secondary and adult learners in both traditional classroom environments, alternative school settings and distributed learning platforms. Regardless of the grade, subject or environment I have been an advocate of digital technology in education, and enthusiastically welcomed George Siemens’ predicted paradigm shift to connectedness enabled through its uses (as cited in Wikipedia, 2013). However, over the past decade this ability to connect through technology has also lead to an increase in cyber-bullying coupled with inherent risks associated with online environments making the connection between cyber-bullying and social media an important area of study. This study began because of a legal case study I was presented with during a graduate course at the University of Victoria concerning issues related to teachers and the law. The case study is based on a high profile YouTube cyber-bullying incident in Canada. Using concepts such as neoliberalism and the promotion of technology as a 21st century tool for schooling, I reviewed Government of Canada and British Columbian research as well as international research regarding the advantages and disadvantages of the use of technology by humans and in education. These documents provided an overview of debates around the benefits for using the Internet, and contrasted this with risks connected to loss of privacy and possible bullying online (cyber-bullying). My methodology for the study is grounded in qualitative research in which I used three different focus groups from which to gather data. The first group included graduate students from the University of Victoria enrolled in Leadership Studies. The second group consisted of members from a Social Justice Committee. The final group represented a team of teachers, administrators and support staff at a Secondary School on a coastal School District in British Columbia. Each focus group observed a video posted on YouTube and the discourse that was left below the posting of the video. Participants were asked to reflect individually, discuss as a group and record their thoughts and feelings for the purposes of the study and as a means to suggest ways to mitigate change. Their comments and suggestions for ways to mitigate change supported research I found and at times pointed towards directions I had yet to consider. Similar to me, the act of viewing and participating in the case study left an impact as to how best to mitigate change through the use of case studies and discussions that helped develop compassion and awareness for cyber-bullying victims. The study concludes with a review of current technology and health and career curriculum as it pertains to issues involving cyber-bullying and promoting socially responsible behaviour on the Internet available to schools in British Columbia, along with information regarding new initiatives including the E.R.A.S.E. bullying website. / Graduate / 0515 / 0710 / 0530 / ssamaras@sd46.bc.ca

With digital media and the web becoming increasingly pervasive in our everyday lives, few historians have considered in depth the impact that this is having on the ways that history is represented and communicated in the public sphere. This thesis is an examination of how the practice of public history in Australia is being reshaped in the Web 2.0 environment. In the context of new media theory, public history practice is considered in relation to identifiable changes in the ways the web is used and understood. / The public historian’s concern with interpreting the past to a public audience means that changing social practices and information patterns are pertinent to their work. This thesis highlights the ways in which different forms of history are being produced, distributed and consumed on the web. It focuses on the potential role of the web user as an active producer of personal and creative interpretations of the past and on how experimental public history practices in the Web 2.0 environment have emerged in response to changing audiences. / This study argues that the rise of Web 2.0 is reflected by personalised, ubiquitous, democratic and innovative public history practices on the web. Through an in depth analysis of The Powerhouse Museum collection search and YouTube as case studies, this thesis shows how increased participation, the proliferation of user-generated content, social networking and existing practices by users in the Web 2.0 environment reshapes public history. / This thesis goes beyond conceiving of the web as a site of historical source material, both digitised and born-digital, to an understanding of the value of participatory media and informal communication in enabling the sharing of historical knowledge and materials between and among networks of people on the web.

This thesis deals with the use of the video as a didactic tool in the education of the physics. Introductory part is theoretic and focuses on classification of didactic tools which can be used for physics teaching. Second part analyses the possibility of capturing physical effects, especially effects with very long or very short duration which cannot be captured by conventional devices. This part is focused on the right selection of physical effects, selecting and setting of suitable devices for capturing and further processing of the recorded video. The next section is based on the previous analysis of physical effects, which are recorded and processed into the form of educational movie. The main result of this thesis is the collection of educational movies of fast and very slow physical effects useful as the didactic tool for the teaching of physics.

The thesis Teaching Microsoft Office using multimedia assesses the possibilities of creating multimedia teaching materials for Microsoft Office software suite. The partial goals include publication on YouTube.com, creation of text support materials, analyzing the availability of educational video materials for Microsoft Office in Czech Republic and abroad, and theoretical analysis of software used in practical part. One of the most interesting results from theoretical part is the amount of online content that exists in video format. Currently it makes up more than 50% of the consumed content and by 2019 it should be up to 80%. Currently, the average user in Czech Republic spends almost 30 hours each month consuming content from YouTube. In the practical part, the author selected the methodology and correct hardware and software equipment for creation of video materials. It was also necessary to create screenplay to ensure the required quality of the final product. Finally, it was necessary to edit created materials in a nonlinear editing program. For this purpose, the author chose Adobe Premiere Pro 2015.1. Next step was to create the appropriate YouTube channel called Abeceda Microsoft Office (Microsoft Office Alphabet) and upload video to it. After that, the author performed pilot tests on a sample of high school students.

"Studies and a career of Czech animator in terms of market economy" answers all basic, practical questions that Czech animation student asks about his future career. It is an information link between school and practice. It delivers facts about current situation on Czech animation scene and presents practical skills which are necessary for setting up an animation career. The goal of a writer was to deliver undistorted information which might be surprisingly realistic or skeptic. Understanding these facts is fundamental, because readers should come up with their own solutions for their future jobs in animation. A broad topic contains information about film or artistic animation, commercial and comissioned jobs, internet animation, basics about animation studios, animation industry and economic aspects of a freelance work. It summaries a purpose of animation schools, including 10 commandments of a student aimed on practical skills to gain during studies.

Technology is changing the structure and dynamics of how humans communicate. Channels of communication are also used for attempts at persuasion, but until now persuasion that (if accepted) would promote the adoption of misinformation could not spread as readily through historical information channels. With the advent of the Internet and World Wide Web this has changed dramatically. In this dissertation it is argued that modern digital communication media such as YouTube, in confluence with what theories of persuasion have to say about how humans deal with persuasion, may create a situation in which misinformation may spread and be accepted on a large scale. The research in this dissertation explores this notion by presenting a group of 120 adolescents who are familiar with the Web with such a misinforming persuasive message. The purpose of which is to determine whether they accept the misinformation presented in the Web-context or are sceptical of it. Different manipulations were done to the persuasive message, known to increase the likelihood of persuasion. The research found that, for this group of participants, no attempt to increase uncritical acceptance of a persuasive message made a statistical difference between different groupings of participants. When intended behaviour was measured in addition to attitude towards the misinformation, participants were even less persuaded. The results are interesting as a starting point for further study, but its generalizability and certain design features must be called into question / Psychology / M.A. (Psychology)

Continuous improvements to the state of the art have made it easier to create, send and receive vast quantities of video over the Internet. Catalysed by these developments, video is now the largest, and fastest growing type of traffic on modern IP networks. In 2015, video was responsible for 70% of all traffic on the Internet, with an compound annual growth rate of 27%. On the other hand, concerns about the growing energy consumption of ICT in general, continue to rise. It is not surprising that there is a significant energy cost associated with these extensive video usage patterns. In this thesis, I examine the energy consumption of typical video configurations during decoding (playback) and encoding through empirical measurements on an experimental test-bed. I then make extrapolations to a global scale to show the opportunity for significant energy savings, achievable by simple modifications to these video configurations. Based on insights gained from these measurements, I propose a novel, energy-aware Quality of Experience (QoE) metric for digital video - the Energy - Video Quality Index (EnVI). Then, I present and evaluate vEQ-benchmark, a benchmarking and measurement tool for the purpose of generating EnVI scores. The tool enables fine-grained resource-usage analyses on video playback systems, and facilitates the creation of statistical models of power usage for these systems. I propose GreenDASH, an energy-aware extension of the existing Dynamic Adaptive Streaming over HTTP standard (DASH). GreenDASH incorporates relevant energy-usage and video quality information into the existing standard. It could enable dynamic, energy-aware adaptation for video in response to energy-usage and user ‘green' preferences. I also evaluate the subjective perception of such energy-aware, adaptive video streaming by means of a user study featuring 36 participants. I examine how video may be adapted to save energy without a significant impact on the Quality of Experience of these users. In summary, this thesis highlights the significant opportunities for energy savings if Internet users gain an awareness about their energy usage, and presents a technical discussion how this can be achieved by straightforward extensions to the current state of the art.

The diploma thesis is dealing with the analysis of the use of social networks by two canadian political parties and their leaders during the Canadian federal election 2015. The thesis refers to the theory of political communication, election campaigns and political marketing as the theoretical basis. It approaches the concept of Web 2.0 and identifies two major social media functions in political communication, dissemination of information and engagement. Use of social media and the representation of the these features is further analyzed by quantitative content analysis on social networks Facebook, Twitter and Youtube. The thesis builds on the past and present social networking research and can serve as a basis for further research into the use of social networks in political communication.

The diploma thesis discusses the phenomenon of tutorials uploaded on the most visited server for viewing and sharing video content nowadays - YouTube. The term tutorial here is used for referring to the specific instructional video content, which primarily aims to show, by means of the step by step illustration, how to proceed within particular activity that usually requires to adopt a certain extent of specialized knowledge or skills. At the same time, the attention is focused on the graphic design and fine art tutorials. The main goal of the thesis is to answer following question: what motivations might internet users have both for the reception and for the production of tutorials. In other words, the thesis is oriented on searching for the highest possible amount of motives that can lead to the viewing as well as to the shooting of this specific media content. Therefore, this requires examining a given field from two different perspectives: from the perspective of receiving viewers and from the perspective of video makers. Whole thesis structure is then subordinated to these two perspectives. The first part introduces the relevant theoretical approaches related to the tutorial reception/production, whereas the second practical part is devoted to the presentation of particular motivation...

Globo e os Protestos ? articularam, no campo destinado aos coment?rios, um esp a?o p?blico voltado ? dissemina??o e circula??o de sentidos sobre quest?es pol?ticas. O v?deo estudado foi publicado por PC Siqueira e Diego Quinteiro, durante os protestos de junho de 2013 no Brasil, para direcionar a compreens?o pol?tica acerca do movime nto vivido naquele per?odo. Segundo eles, os protestos possu?am posi??o pol?tica de esquerda e, por isso, os manifestantes deviam rejeitar a cobertura realizada pela Rede Globo (um ve?culo com ideais de direita) e permitir a participa??o de partidos ligado s ao espectro ideol?gico da esquerda. Essa narrativa gerou empatia e controv?rsias por parte dos comentaristas, o que produziu no ?mbito dos coment?rios, um intenso processo argumentativo acerca dessas teses (direita e esquerda). Para entender o fen?meno, realizamos uma pesquisa explorat? ria com abordagem qualitativa, t endo como principal procedimento metodol?gico a an?lise etn ometodol?gica do discurso.

We are interested in examining the way in which the commentators of the video " Globo e os Protestos " articulated in the field intended for comments, a public space directed to the dissemination and circulation of meanings about policy issues. The video studied was published by PC Siqueira and Diego Quint eiro , during the June 2013 protests in Br azil, to direct the political understanding of the movement lived in that period. According to them, the protests had left political position and therefore the protesters should reject the coverage by TV Globo (a comunication vehicle with ideals of right) and allow the participation of political parties linked to the ideological left spectrum. This narrative generated empathy and controversy betwe en commentators, which produced in the comments, an intense argumentative process about these theses (right and left). To understand the phenomenon, we conducted an exploratory qualitative research, the main methodological procedure was a ethnomethodological discourse analysis. We seek the observation of the ways in which the commentators es tablished talks about politics in the comments space, for, thereafter , organize categories of analysis based on identified discursive recurrences. The empirical reflections are supported from discussions about the YouTube potential, while digital media com prising massive strategies and while articulating space in the engagement of individuals in political issues; also confront the aspects involved in the conversation practices that results in sociability dynamics and , especially , in conflict, on the socio - t echnical networks; and finally, we propose a reflection about the circuit actuation in which the people take ownership and realize new readings about the products received. Concluding that the use of digital media , such as YouTube, has caused significant c hanges in the forms of production and reception of symbolic products and ways in which people participate in political issues concerning life in society.
