Services such as LiveJournal allow their users to specify who their “friends” are, and thus a social network is formed. Some users choose not to disclose personal information which their friends list. This paper will explore the relationship between users with the intent of being able to make a prediction of a users age and country of residence based on the information given by their friends on this social network.

We evaluated whether "seminar blogs" enhanced learning in a large graduate-level introductory public health school class.Methods. Sixty students were divided into 6 online blog groups. Students posted their assignments (case analyses, news commentaries), prompting comments from other students. Anonymous poll surveys of students were conducted at midpoint and at the end of the course.Results. Sixty percent reported that blog participation enriched their learning quite a bit, 34% a small amount, and 6% not at all; 54% said that the blogs provided opportunities to learn from classmates. When comparing writing on the blog to speaking in class, 60% found it easier, 30% about the same, and 10% harder. About 65% said that skills attained by participating in blogs were useful for current or future work. Major criticisms involved time issues.Conclusions. Small seminar blogs offer opportunities for increased student participation, interaction, and learning. To be most effective and appealing, assignments for postings need to allow sufficient time for commentary. This educational technology has potential to expand the classroom experience and is worthy of further development and testing. 10.2105/AJPH.2008.133694 Using Seminar Blogs To Enhance Student Participation and Learning in Public Health School Classes Rose Goldman Amy Cohen Fred Sheahan doi:10.2105/AJPH.2008.133694 Am J Public Health (16 July 2008), AJPH.2008.133694. 2008-07-21T07:14:06-00:00 2008 Am J Public Health AJPH.2008.133694 blogs training web20 http://www.citeulike.org/user/noahwf/article/3023144 <i>(26 February 2008)</i><br /><br />This unique take on quests, incorporating literary and digital theory, provides an excellent resource for game developers.

Our first browser is based on a traditional, folder-based layout that utilizes either the user's manually created organization structure, or a system-generated structure. Our second browser uses a novel interface that is based on a vertical, zoomable timeline. This timeline browser does not require users to organize their photos, but instead, relies solely on system-generated structure. Our system creates a hierarchical structure of the user's photos by applying time-based clustering to identify subsets of photos that are likely to be related. In a user experiment, we compared users' searching and browsing performance across these browsers, using each user's own photo collection. Photo collection sizes varied between 500 and 3000 photographs. Our results show that our timeline browser is at least as effective for searching and browsing tasks as a traditional browser that requires users to manually organize their photos.

How do such links evolve? Does the popularity of old blog posts drop exponentially with time? These are some of the questions that we address in this work. Our goal is to build a model that generates realistic cascades, so that it can help us with link prediction and outlier detection. Blogs (weblogs) have become an important medium of information because of their timely publication, ease of use, and wide availability. In fact, they often make headlines, by discussing and discovering evidence about political events and facts. Often blogs link to one another, creating a publicly available record of how information and influence spreads through an underlying social network. Aggregating links from several blog posts creates a directed graph which we analyze to discover the patterns of information propagation in blogspace, and thereby understand the underlying social network. Not only are blogs interesting on their own merit, but our analysis also sheds light on how rumors, viruses, and ideas propagate over social and computer networks. Here we report some surprising findings of the blog linking and information propagation structure, after we analyzed one of the largest available datasets, with 45,000 blogs and ~ 2.2 million blog-postings. Our analysis also sheds light on how rumors, viruses, and ideas propagate over social and computer networks. We also present a simple model that mimics the spread of information on the blogosphere, and produces information cascades very similar to those found in real life.

The rise of customisable media has mainstream thinkers, used to a near-monopoly on attention, running scared. Legal scholar Cass Sunstein makes the case for a more robust information diet from a slightly left of centre point of view in _republic.com_. Building on the ideas of the Technorealist movement, Sunstein focuses on the increasing volume of extremist voices as people choose to read or listen to only those points of view they already share. Though it seems that he occasionally overstates his case--it seems unlikely that we'll ever really be able to filter every unwanted or unexpected opinion--he does score some solid blows against the current, more or less laissez-faire system. His prose is clear and accessible, exactly the kind of reasoned discourse he values and wants to preserve. His proposed programme of government-sponsored and mandated public media spaces probably won't rouse many readers to wholehearted endorsement, but the suggestion that we have problems brewing ought to be enough to spur further thought. Since everyone from the American Nazi Party to the Zapatistas has found a stronger voice via the Internet, it's little wonder that we're starting to hear concerned prophets warning of a new Babel.

We test this theory empirically by analyzing—both quantitatively and qualitatively—Web links among the writings of top conservative and liberal bloggers. Given our use of novel methods, we discuss in detail our sampling and data collection methodologies. We find that widely read political bloggers are much more likely to link to others who share their political views. However, we find no increase in this pattern over time. We also analyze the content of the links and find that while many of the links are based on straw-man arguments, bloggers across the political spectrum also address each others’ writing substantively, both in agreement and disagreement.

The blog was established using free online software to provide more learning exercises for students and to collect feedback about course proceedings. The instructor posted exercises such as multiple choice and true/false questions and invited students to publish answers. Students were also encouraged to post comments about difficult parts of the course that needed clarification. Students contributed 149 comments, mostly as answers in response to thirteen posts of exercises over three months. All users of the blog who responded to a questionnaire considered it useful, and most of them expressed the opinion that blogs should be used in other courses. The main reason that students reported for not using the blog was lack of time. Statistically significant differences in examination performance existed between students who used the blog and those who did not. Based on these findings, the blog achieved its purposes, which were to enhance instructor communication with students and provide students with practice exercises to improve their understanding of dental terminology. Further research about the application of blogging and its potential to enhance dental education is needed.

The main idea is to perform re-ranking based on centrality within bipartite graphs of documents (on one side) and clusters (on the other side), on the premise that these are mutually reinforcing entities. Links between entities are created via consideration of language models induced from them. We find that our cluster-document graphs give rise to much better retrieval performance than previously proposed document-only graphs do. For example, authority-based re-ranking of documents via a HITS-style cluster-based approach outperforms a previously-proposed PageRank-inspired algorithm applied to solely-document graphs. Moreover, we also show that computing authority scores for clusters constitutes an effective method for identifying clusters containing a large percentage of relevant documents. Respect My Authority!

Factors that have an influence on web navigation behavior were identified with the aid of task analysis, and their relevance in predicting task outcomes (performance, satisfaction, perceived disorientation) was tested with the aid of multiple regression analysis. Several types of navigation metrics were calculated based on web logging data and used as indicators of user characteristics and task outcomes. Results show that spatial-semantic cognitive mechanisms seem to be crucial in adequately performing web navigation tasks. The fact that user characteristics and task outcomes can be estimated with reasonable accuracy based on navigation metrics suggests the possibility of building adaptive navigation support in web applications.

Based on theories of adaptive learning and field-dependence, two human-computer interfaces were developed which were intended to compensate for the inability of low spatial individuals to readily construct visual mental models of a menu system's structure. The two compensatory interfaces included: a 2D visual hierarchy and a linear structure. The information search performance of high and low spatial individuals was compared on the two compensatory interfaces and a third challenge match interface, which challenged individuals to construct a mental model of a hierarchical menu system in order to perform efficiently. The visual mediators were successful in accommodating low spatial individuals, as indicated by the lack of any significant performance differences being detected between the high and low spatial groups on the two compensatory interfaces. High spatial individuals outperformed low spatial individuals only when information search tasks required the use of spatial ability in mentally constructing a model of the organization and structure of embedded task information. The key factor in the accommodation process was the elimination of the need to mentally visualize the structure of <i>embedded</i> task information. These results indicate that visualization techniques can be successfully used to enhance the information search performance of low spatial individuals.

To this end, we reverse-engineer the seminal papers on MapReduce and Sawzall, and we capture our findings as an executable specification. We also identify and resolve some obscurities in the informal presentation given in the seminal papers. We use typed functional programming (specifically Haskell) as a tool for design recovery and executable specification. Our development comprises three components: (i) the basic program skeleton that underlies MapReduce computations; (ii) the opportunities for parallelism in executing MapReduce computations; (iii) the fundamental characteristics of Sawzall's aggregators as an advancement of the MapReduce approach.

Because he had been trained as an ethnographer and social psychologist, Sudnow was attentive to what he experienced in ways that other novice pianists are not. The result, first published in 1978 and now considered by many to be a classic, was arguably the finest and most detailed account of skill development ever published.<br /> <br /> Looking back after more than twenty years, Sudnow was struck by the extent to which he had allowed his academic background to shape the book's language. He realized that he could now do a much better job of describing his experiences in a way that would not require facility with formal social science and philosophical discourse. The result is a revised version of the book that carries the same intellectual energy as the original but is accessible to a much wider audience.

Only now, however, with <i>Electronic Literature</i> by N. Katherine Hayles, do we have the first systematic survey of the field and an analysis of its importance, breadth, and wide-ranging implications for literary study. <P>Hayles's book is designed to help electronic literature move into the classroom. Her systematic survey of the field addresses its major genres, the challenges it poses to traditional literary theory, and the complex and compelling issues at stake. She develops a theoretical framework for understanding how electronic literature both draws on the print tradition and requires new reading and interpretive strategies. Grounding her approach in the evolutionary dynamic between humans and technology, Hayles argues that neither the body nor the machine should be given absolute theoretical priority. Rather, she focuses on the interconnections between embodied writers and users and the intelligent machines that perform electronic texts. <P>Through close readings of important works, Hayles demonstrates that a new mode of narration is emerging that differs significantly from previous models. Key to her argument is the observation that almost all contemporary literature has its genesis as electronic files, so that print becomes a specific mode for electronic text rather than an entirely different medium. Hayles illustrates the implications of this condition with three contemporary novels that bear the mark of the digital. <P>Included with the book is a CD, <b><i>The Electronic Literature Collection</i>, Volume 1</b>, containing sixty new and recent works of electronic literature with keyword index, authors' notes, and editorial headnotes. Representing multiple modalities of electronic writing--hypertext fiction, kinetic poetry, generative and combinatory forms, network writing, codework, 3D, narrative animations, installation pieces, and Flash poetry--the ELC 1 encompasses comparatively low-tech work alongside heavily coded pieces. Complementing the text and the CD-ROM is a website offering resources for teachers and students, including sample syllabi, original essays, author biographies, and useful links. Together, the three elements provide an exceptional pedagogical opportunity.

Reviewing 24 blogging studies, they focus on the four strategies that researchers have employed to sample bloggers and blogs on the Internet: self-selected and convenience samples, sampling through blog hosts, sampling with the assistance of blog aggregators or indexing websites, and sampling from ready-published lists of blogs. They look closely at the practicality of such methods and discuss their tradeoffs. They then examine several techniques that researchers utilize to sample elusive, networked and rare populations in an offline context, emphasizing how they can be applied to sampling bloggers and blogs. In conclusion, they propose that these suggestions be applied to sampling methodologies concerning other Internet-based communities.

Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamic aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given URL. We also present a dynamic model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.

However, it is uncertain as to why traditional computer-mediated communication (CMC) applications should be replaced with blogs. It is time to comprehensively explore the effects of educational blogs by considering the CMC tools. This paper reviews prior studies and develops a model for the use of blogs in educational contexts by taking into account socio-technical systems theory. The model contributes to interactivity, an open system, a visualization tool, and a decentralized environment of online communication circumstance.

The contemporary relevance of the web as a key site for the articulation of social issues should make it a prime target for critical discourse analysts with a political and emancipatory brief. Nonetheless, CDA publications are still predominantly based on conventional, non-electronic sources of data. This article discusses the analytic potential that web-based data opens up and also identifies the specific challenges that arise as a result. These are linked to the size of the web, its diversity, ephemeral quality, interactivity, and multimodality. Indicating directions in which future research might proceed, the article makes a plea for more critical discourse analysts to work with web-based corpora. 10.1177/0957926505056661 Time to get wired: Using web-based corpora in critical discourse analysis Gerlinde Mautner doi:10.1177/0957926505056661 Discourse Society, Vol. 16, No. 6.

Instead it argues that web texts cannot be understood without reference to their specific contexts of production and consumption. As part of the construction of an alternative to existing analytical approaches to the web text contemporary practice in web design is surveyed, as are its relations with the culture of particular groups of producers. Drawing on an interdisciplinary framework allied to the field of British media and cultural studies, this paper suggests how the analysis of the web site might be approached in terms of its status as an emergent media/cultural form. It discusses how such forms might be understood in terms of the shared social conventions which inflect their production. It argues that web sites can neither be analysed in terms of generic hypertext or as a homogeneous genre and that rather the formation of groupings of sites in line with the ideologies, values and preoccupations of their producers require concrete analysis together with further research into specific practices of 'reading' web texts. 10.1177/135485650000600304 Approaches to Analysing the Web Text: A Consideration of the Web Site as an Emergent Cultural Form Miriam Rivett doi:10.1177/135485650000600304 Convergence, Vol. 6, No. 3.

Despite the apparent lack of order, the 50 million edits by 4.8 million contributors to the 1.5 million articles in the English-language Wikipedia follow strong certain overall regularities. We show that the accretion of edits to an article is described by a simple stochastic mechanism, resulting in a heavy tail of highly visible articles with a large number of edits. We also demonstrate a crucial correlation between article quality and number of edits, which validates Wikipedia as a successful collaborative effort.

Books on compilers are better described as wizard-talk: written by and for a clique of all-knowing practitioners. Real-life compilers are too complex to serve as an educational tool. And the gap between real-life compilers and the educational toy compilers is too wide. The novice compiler writer stands puzzled facing an impenetrable barrier, “better write an interpreter instead.” The goal of this paper is to break that barrier. We show that building a compiler can be as easy as building an interpreter. The compiler we construct accepts a large subset of the Scheme programming language and produces assembly code for the Intel-x86 architecture, the dominant architecture of personal computing. The development of the compiler is broken into many small incremental steps. Every step yields a fully working compiler for a progressively expanding subset of Scheme. Every compiler step produces real assembly code that can be assembled then executed directly by the hardware. We assume that the reader is familiar with the basic computer architecture: its components and execution model. Detailed knowledge of the Intel-x86 architecture is not required. The development of the compiler is described in detail in an extended tutorial. Supporting material for the tutorial such as an automated testing facility coupled with a comprehensive test suite are provided with the tutorial. It is our hope that current and future implementors of Scheme find in this paper the motivation for developing high-performance compilers and the means for achieving that goal.

The problem becomes more severe with the increasing fraction of multimedia data, from which it is difficult to extract some conceptual description of their contents. One way to overcome this problem are social bookmark tools, which are rapidly emerging on the web. In such systems, users are setting up lightweight conceptual structures called folksonomies, and overcome thus the knowledge acquisition bottleneck. As more and more people participate in the effort, the use of a common vocabulary becomes more and more stable. We present an approach for discovering topic-specific trends within folksonomies. It is based on a differential adaptation of the PageRank algorithm to the triadic hypergraph structure of a folksonomy. The approach allows for any kind of data, as it does not rely on the internal structure of the documents. In particular, this allows to consider different data types in the same analysis step. We run experiments on a large-scale real-world snapshot of a social bookmarking system.

A well-designed interface is essential in order to find everything necessary and meet the requirements of both the average user and users with special needs. Proper placement of objects on the screen is important to decrease perception time. One of the well-known researchers of web ergonomics, Jakob Nielsen (2006) established in an eye-tracking experiment that users scan displayed homepages in an F shape. In the present project the task was to find similar shapes in a number of playful visual search games. Several multimedia tasks were developed for this investigation. Our experiments included normal users and users with intellectual disabilities. We tested whether the characteristic searching routes and navigation methods differed between normal users and those with intellectual disabilities. The results of this investigation can inform the design and position of graphical user interface elements.

This history of hypertext tended to portray contradicting archetypes or pure forms that concrete developments never fulfilled. We argue that hypertext has long been a cultural analogy rather than a simple enactment or fulfillment of desires. To assist in creating a more open, constructive vision of hypertext, we gather three differing but connected tropes for hypertext from this history: hypertext as kinship, hypertext as battlefield, and hypertext as rhizome. Although these tropes are only three among many possibilities, we provisionally play them off one another to deconstruct and reconstruct hypertext theory and practice, and to demonstrate potentials for moving beyond archetypes in theorizing and practicing hypertext.
