Item 3D modeling tool selection for research-based educational games: an experience(2016-05) Qiu, Yajun, M.A.; Liu, Min, Ed. D.; Horton, LucasNowadays, serious games are gaining wide recognition, and many studies have been conducted regarding their implementation. However, the value of serious games in education and research is still subject to debate. Serious game designers might have difficulty selecting appropriate tools for 3D game development since most 3D modeling tools and game engines are designed for developing commercial games. This report highlights the value of research-based educational games and suggests an Education Modeling Tool Framework for 3D modeling tools and game engine selection. The author modifies Petridis and De Freitas’s (2012) framework for serious game engine selection to meet the specialized needs of research-based educational games. The unique features identified are high compatibility with game engines, moderate visual fidelity, smooth learning curve, ample documentation and support, and low cost. Then, the report discusses the actual use of the Education Modeling Tool Framework for the development of a research-based educational game Alien Rescue. The framework was applied in selecting 3D modeling tools as well as game engines for Alien Rescue development. Finally, the conclusion includes suggestions for possible applications and utility of the Education Modeling Tool Framework in other research-based educational game projects.Item ccMixter : creative commons in action(2011-08) Dunham, Ian Paul; Erlmann, Veit; Slawek, StephenccMixter.org, an online remix community that uses Creative Commons licenses to protect and promote their work, is a unique site of musical activity whose discourse is shaped by an egalitarian ideology. However, simultaneously exists a hierarchical structure in which some remixes are considered better than others. This report explores the coexistence of these two paradigms, and seeks to frame the discussion within the context of current IP policy politics, the open source movement, and fundamental shifts that the Internet has caused in communication.Item Data-mining the Ubuntu Linux Distribution for bug analysis and resolution(2012-08) Arges, Christopher John; Stewart, Kate; Ghosh, JoydeepThe Ubuntu Linux Distribution represents a massive investment of time and human effort to produce a reliable computing experience for users. To accomplish these goals, software bugs must be tracked and fixed. However, as the number of users increase and bug reports grow advanced tools such as data mining must be used to increase the effectiveness of all contributors to the project. Thus, this report involved collecting a large amount of bug reports into a database and calculating relevant statistics. Because of the diversity and quantity of bug reports, contributors must find which bugs are most relevant and important to work on. One study in this report created an automatic way to determine who is best fit to solve a particular bug by using classification techniques. In addition, this report explores how to initially classify if a bug report will be eventually marked invalid or not.Item Interactive engagement with an open source community : a study of the relationships between organizations and an open source software community(2013-05) Sims, Jonathan Paul; Crossland, Craig; Henderson, Andrew DuaneThis dissertation theoretically develops and empirically tests a model of interactive firm engagement with an open source software community. An inductive pilot study and subsequent interview analysis suggest that the nature of the relationship between a firm and an open source community varies in the degree by which a firm both "takes from" and "gives to" the community. I propose that a firm will experience direct effects from both giving to and taking from the community, and further propose that the interaction of these two behaviors, which I call interactive engagement, will lead to three firm-level consequences: an increase in the number of new products, higher levels of incremental (as opposed to radical) innovation, and shortened development and debug time. I test these hypotheses using regression analysis of questionnaire responses collected from 250 organizations that work with a popular open source software community.Item Open-source software development and user-centered design: a study of open-source practices and participants(Texas Tech University, 2006-08) Yeats, Dave; Dragga, Sam A.; Koerber, Amy; Carter, Joyce L.; Zdenek, SeanDespite its seemingly attractive adherence to user-centered design principles of participatory design and democratized technology, open-source software fails to effectively address the usability needs of typical software users. Instead, it embodies a system-centered design approach facilitated by the efforts of developer-users. Through a plurality of research methods including discourse analysis, rhetorical analysis, and primary research methods such as interviews and surveys, this study attempts to examine the representations of the "user" in the communication and development practices of open-source software developers.
