Description
Over 2 billion people are using online social network services, such as Facebook, Twitter, Google+, LinkedIn, and Pinterest. Users update their status, post their photos, share their information, and chat with others in these social network sites every day; however, not everyone shares the same amount of information. This thesis explores methods of linking publicly available data sources as a means of extrapolating missing information of Facebook. An application named "Visual Friends Income Map" has been created on Facebook to collect social network data and explore geodemographic properties to link publicly available data, such as the US census data. Multiple predictors are implemented to link data sets and extrapolate missing information from Facebook with accurate predictions. The location based predictor matches Facebook users' locations with census data at the city level for income and demographic predictions. Age and relationship based predictors are created to improve the accuracy of the proposed location based predictor utilizing social network link information. In the case where a user does not share any location information on their Facebook profile, a kernel density estimation location predictor is created. This predictor utilizes publicly available telephone record information of all people with the same surname of this user in the US to create a likelihood distribution of the user's location. This is combined with the user's IP level information in order to narrow the probability estimation down to a local regional constraint.

Description
The goal of this research was to understand the different kinds of learning that take place in Mod The Sims (MTS), an online Sims gaming community. The study aimed to explore users' experiences and to understand learning practices that are not commonly observed in formal educational settings. To achieve this goal, the researcher conducted a four-year virtual ethnographic study that followed guidelines set forth in Hine (2000). After Hine, the study focused on understanding the complexity of the relationships between technology and social interactions among people, with a particular emphasis on investigating how participants shaped both the culture and structure of the affinity space. The format for the dissertation consists of an introduction, three core chapters that present different sets of findings, and a concluding chapter. Each of the core chapters, which can stand alone as separate studies, applies different theoretical lenses and analytic methods and uses a separate data set. The data corpus includes hundreds of thread posts, member profiles, online interview data obtained through email and personal messaging (PM), numerous screenshots, field notes, and additional artifacts, such as college coursework shared by a participant. Chapter 2 examines thread posts to understand the social support system in MTS and the language learning practices of one member who was a non-English speaker. Chapter 3 analyzes thread posts from administrative staff and users in MTS to identify patterns of interactions, with the goal of ascertaining how users contribute to the ongoing design and redesign of the site. Chapter 4 investigates user-generated tutorials to understand the nature of these instructional texts and how they are adapted to an online context. The final chapter (Chapter 5) presents conclusions about how the analyses overall represent examples of participatory learning practices that expand our understanding of 21st century learning. Finally, the chapter offers theoretical and practical implications, reflections on lessons learned, and suggestions for future research.

Description
This research study looks at the design and development of an online concussion awareness education module. The Keep Your Head in the Game: Concussion Awareness Training for High School Athletes, or Brainbook, is a stand-alone e-learning module designed to run for fifty minutes and to be highly interactive using short video clips with associated comments as well as polling features to allow students to experience the content as they are learning. It was designed to provide the instruction through a framework that resembles social networking to increase relevance and engagement to the high school student-athlete population it was created for. The content is delivered through the presentation of an online conversation or a "feed" where characters with varying attitudes towards concussion, with contributions from a doctor and professional athlete, discuss concussions from their experiences and beliefs. The instructional goals of the module are to increase the athletes understanding and personal application of the causes and effects of concussions, and to motivate a change in attitude and behavior related to the perception, recognition, and care of head injuries. The design and development of this online educational module followed the tenets of design and development research as determined by Richey and Klein (2007), where the tasks of completing the design and development of the product were combined with studying the process. The study focused on what could be learned during the phases of design and development, identifying challenges that were encountered designing education that resembles social networking, testing the effectiveness of the module in relation to meeting the instructional objectives, and creating guidelines and best practices that contribute to the field of instructional design.
This design and development project was found to be a success by the design team, the client, and outside entities. Findings of the study include a breakdown of the most impactful decisions made by the design team in the design and development process, the results of the team member and client interviews to provide additional insight into the process, and results from the student athlete post-module design and attitude surveys informing if attitude change indeed occurred as a result of this educational intervention. Brainbook also received much coverage in the media and has progressed on to version 2.0, additional measures of success of the project.
