Fostering Public Good Contributions with Symbolic Awards: A Large-Scale Natural Field Experiment at Wikipedia

This natural field experiment tests the effects of purely symbolic awards on volunteer retention in a public goods context. The experiment is conducted at Wikipedia, which faces declining editor retention rates, particularly among newcomers. Randomization assures that award receipt is orthogonal to previous performance. The analysis reveals that awards have a sizeable effect on newcomer retention, which persists over the four quarters following the initial intervention. This is noteworthy for indicating that awards for volunteers can be effective even if they have no impact on the volunteers’ future career opportunities. The awards are purely symbolic, and the status increment they produce is limited to the recipients’ pseudonymous online identities in a community they have just recently joined. The results can be explained by enhanced self-identification with the community, but they are also in line with recent findings on the role of status and reputation, recognition, and evaluation potential in online communities.

Reputation assessment in collaborative environments.

The popularity of open collaboration platforms is strongly related to the popularity of Internet: the growing of the latter (in technology and users) is a spring to the former. With the advent of Web 2.0, not only the Internet users became from passive receiver of published content to active producer of content, but also active reviewers and editors of content. With the increase of popularity of these platforms, some new interesting problems arise related on how to choose the best one, how to choose the collaborators and how evaluate the quality of the final work. This evolution has brought much benefit to the Internet community, especially related to the availability of free content, but also gave rise to the problem of how much this content, or these people, may be trusted. The purpose of this thesis is to present different reputation systems suitable for collaborative environments; to show that we must use very different techniques to obtain the best from the data we are dealing with and, eventually, to compare reputations systems and recommender systems and show that, under some strict circumstances, they become similar enough and we can just make minor adjustment to one to obtain the other

Open Educational Practices and Resources. OLCOS Roadmap 2012

As a Transversal Action under the European eLearning Programme, the Open e-Learning Content Observatory Services (OLCOS) project carries out a set of activities that aim at fostering the creation, sharing and re-use of Open Educational Resources (OER) in Europe and beyond.OER are understood to comprise content for teaching and learning, software-based tools and services, and licenses that allow for open development and re-use of content, tools and services.The OLCOS road mapping work was conducted to provide decision makers with an overview of current and likely future developments in OER and recommendations on how various challenges in OER could be addressed.While the results of the road mapping will provide some basis for policy and institutional planning, strategic leadership and decision making is needed for implementing measures that are likely to promote a further uptake of open educational practices and resources.OER are understood to be an important element of policies that want to leverage education and lifelong learning for the knowledge economy and society. However, OLCOS emphasises that it is crucial to also promote innovation and change in educational practices.In particular, OLCOS warns that delivering OER to the still dominant model of teachercentred knowledge transfer will have little effect on equipping teachers, students and workers with the competences, knowledge and skills to participate successfully in the knowledge economy and society.This report emphasises the need to foster open practices of teaching and learning that are informed by a competency-based educational framework. However, it is understood that a shift towards such practices will only happen in the longer term in a step-by-step process. Bringing about this shift will require targeted and sustained efforts by educational leaders at all levels

Internet based molecular collaborative and publishing tools

The scientific electronic publishing model has hitherto been an Internet based delivery of electronic articles that are essentially replicas of their paper counterparts. They contain little in the way of added semantics that may better expose the science, assist the peer review process and facilitate follow on collaborations, even though the enabling technologies have been around for some time and are mature. This thesis will examine the evolution of chemical electronic publishing over the past 15 years. It will illustrate, which the help of two frameworks, how publishers should be exploiting technologies to improve the semantics of chemical journal articles, namely their value added features and relationships with other chemical resources on the Web. The first framework is an early exemplar of structured and scalable electronic publishing where a Web content management system and a molecular database are integrated. It employs a test bed of articles from several RSC journals and supporting molecular coordinate and connectivity information. The value of converting 3D molecular expressions in chemical file formats, such as the MOL file, into more generic 3D graphics formats, such as Web3D, is assessed. This exemplar highlights the use of metadata management for bidirectional hyperlink maintenance in electronic publishing. The second framework repurposes this metadata management concept into a Semantic Web application called SemanticEye. SemanticEye demonstrates how relationships between chemical electronic articles and other chemical resources are established. It adapts the successful semantic model used for digital music metadata management by popular applications such as iTunes. Globally unique identifiers enable relationships to be established between articles and other resources on the Web and SemanticEye implements two: the Document Object Identifier (DOI) for articles and the IUPAC International Chemical Identifier (InChI) for molecules. SemanticEye’s potential as a framework for seeding collaborations between researchers, who have hitherto never met, is explored using FOAF, the friend-of-a-friend Semantic Web standard for social networks

Emerging Genres Of Online Technical Communciation

Emerging Genres of Online Technical Communication is a study of how the proliferation of non-professional participation has the potential to significantly change the shape of technical communication. More specifically, I use a genre analysis methodology to investigate three forms of user-generated content: crowdsourced documentation wikis, video games user reviews, and video game open development. In the first study, I analyze five crowdsourced documentation wikis and find systemic inconsistency in the workflow and content quality of the documentation. Subsequently, I argue that practitioners should use minimalist documentation theory to design more effective user-centered author support for the wikis. My second chapter uses Bhatian move-strategy analysis to investigate variation in the genre structure of a corpus of 180 video game reviews sampled from six websites. Based on the results, I argue that there are emerging genre variations that respond to both the exigencies of specific sites and also to new types of audiences. My third body chapter explores communication practices tied to the open video game development methodology where game prototypes are publicly distributed in order to support a more transparent development process. By mapping the activities and genres used to facilitate this development process, I argue past breakdowns in the system can be traced back to differing goals among stakeholders and to a deficit in genre knowledge that lowers the usefulness of some communications. Finally, my conclusion discusses the pedagogical implications of these emerging genres. Ultimately, I argue that, as professional technical communicators become less involved with developing content and more engaged with supporting and managing communities that develop content, we need to reorient some of our instruction toward writing studies practices that can help students become effective communication researchers and facilitators
