Deliverable D3.1 (Part A) of the UNCOVER FP7-funded project under contract number 282574: Publication Bias: Identification of the Internet Community The main goal of task 3.1 (Part A) was to identify the ‘publication bias’ community on the internet by means of social network analysis. Measures were established to identify organisations with key positions in this community network to finally identify specific roles of member organisations of the community. The analysis revealed that new and sometimes unconventional types of organisations are currently gaining key position on the internet. Besides blogs, we identified numerous e-journals, social networks, and video platforms, like YouTube with videos about conference presentations, discussion forums and other new services indicating a structural change on the science and publication infrastructure.

Contract N o 282574 1 Executive Summary The main goal of task 3.1 (Part A) was to define the ‘publication bias’ community on the internet by means of social network analysis. Measures were established to identify key positions and roles of organisations within the community network to finally identify prominent member organisations. In this context, the term ‘organisation’ refers to the responsible entity behind a website. A community identification agent (CIA) was used to systematically locate and archive content and activities relating to ‘publication bias’ such as conferences, pressure group sites, standardization organisations, public forums and blogs with publicly accessible sites. The overall aim was to gain a deep insight into the community structure of the publication bias community on the internet through social network analysis, web crawling and site statistics. About 220,000 internet sites were scanned for ‘publication bias’ and related content. About 17,000 sites were identified as being part of the ‘publication bias’ community network on the internet. These sites are operated by 483 website providers. Based on these findings, a network analysis was carried out to explore the community structure. Finally, organisation types were classified according to the services they offer on their internet sites. This revealed that new and sometimes unconventional types of organisations are currently gaining importance in the ‘publication bias’ community. Blogs, e-journals, social networks, and video platforms, like YouTube, with videos about conference presentations, discussion forums and other new services can be considered potential sources for information about the current discussion on publication bias. To address the discussion on publication bias in new media, new forms of information management are necessary. The automatic identification of epistemic communities is only the first step in a direction of automatic knowledge management. It will be a competitive advantage in the publication bias community to use automatic issue management systems with issue identification, issue tracking, weak signal detection for emerging issues and other. Although automatic issue management cannot substitute the manual research, it can support researchers with respect to their information management. One of the main results of task 3.1 (Part A) is a list with organisations (identified by domain name) and their relating network position. The individual position of an organisation can be seen as an indicator for whether the organisation tends to be either an information hub for the community (a site with numerous outbound links) or whether the organisation is accepted as an authority by the community (a site with numerous

  • Nerd/Geek Masculinity: Technocracy, Rationality
    NERD/GEEK MASCULINITY: TECHNOCRACY, RATIONALITY, AND GENDER IN NERD CULTURE’S COUNTERMASCULINE HEGEMONY A Dissertation by ELEANOR AMARANTH LOCKHART Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Kristan Poirot Committee Members, Tasha Dubriwny Jennifer Mercieca Claire Katz Head of Department, J. Kevin Barge August 2015 Major Subject: Communication Copyright 2015 Eleanor Amaranth Lockhart ABSTRACT Nerd and geek culture have become subjects of increasing public concern in recent years, with growing visibility and power for technical professions and increasing relevance of video games, science fiction, and fantasy in popular culture. As a subculture, nerd/geek culture tends to be described in terms of the experiences of men and boys who are unpopular because of their niche interests or lack of social skills. This dissertation proposes the concept of nerd/geek masculinity to understand discourses of hegemonic masculinity in nerd/geek culture. Examining three case studies, the novel Ender’s Game by Orson Scott Card, the neoreactionary political ideology, and the #GamerGate controversy, the dissertation suggests that nerd/geek masculinity responds to a perceived emasculation of men who identify as nerds or geeks by constructing the interests, skills, and behaviors of nerd/geek culture as inherently male traits. In this way, nerd/geek masculinity turns the very traits nerds and geeks are often mocked for into evidence of manhood – as the cost of excluding women and queer people from nerd and geek culture. ii DEDICATION To my friends and family who have supported me through this process of scholarship and survival, especially Aeva Palecek and Emily O’Leary… you are my dearest friends.

    Nassim Haramein - RationalWiki http://rationalwiki.org/wiki/Nassim_Haramein Nassim Haramein From RationalWiki Nassim Haramein is a physics crank, one of the many who claim to have uncovered the holy grail of physics, the "Unified Field Theory". Despite his claims, he's virtually unknown to mainstream physics, and the only people who take him seriously are the kind of people who listen to Coast to Coast AM [1] . For a taste of his claims, assorted clips from his talks can be found on YouTube. Many of his papers can be downloaded from his website. He is the founder of The Resonance Project , a website and foundation concerned with his Unified Physics, and the "Hawaii Institute for Unified Physics". Despite this, his article keeps getting deleted from Wikipedia on notability grounds.

The Black Whole He is featured in the self-directed Gaiam film The Black Whole, a 2011 documentary-type movie starring Haramein and his "vacuum is the key to everything" claims. In the movie, he addresses the little he understands of quantum mechanics, the phi ratio, tetrahedrons, symmetries in the structure of the vacuum, and, of course, black holes, which, according to Haramein, are everywhere and everything; we are constantly appearing and disappearing at the speed of light, so, half of the time, we are vacuum, made of "blocks" of 64 tetrahedrons, arranged in such a way that a mini-black hole is created right at the centre of each "block", thus proving that we all have four sides.[citation needed ] The Schwarzschild proton Haramein proposed "the Schwarzschild proton" - a theoretical model of the proton where two black holes "orbit" one another.

It resembled the contemporary doctrine of fascism in many particulars, such as its authoritarianism and ethnic nationalism, although it had a much stronger emphasis on race. It destroyed terrorized ruled Germany from 1933 to 1945, during a period known as the "Third Reich."

The movement is made up largely of young Internet- "alt-right". dwellers, and is itself the merger of traditional white nationalists, neo- Nazis , neo-Confederates, and far-right internet groups (such as the Frogs and swastikas neoreactionary movement and right-wing elements of the Gamergate Alt-right movement and the Manosphere). The alt-right consensus generally rests at the juncture of those three groups. The alt-right is also united by its support for U.S. Republican President Donald Trump. The term originated with Richard Spencer's white nationalist magazine/blog Alternative Right , which was nicknamed "AltRight".

  • The Perils of Classifying Political Orientation from Text
    The Perils of Classifying Political Orientation From Text Hao Yan, Allen Lavoie?, and Sanmay Das Washington University in St. Louis, St. Louis, USA {haoyan,allenlavoie,sanmay}@wustl.edu Abstract. Political communication often takes complex linguistic forms. Un- derstanding political ideology from text is an important methodological task in studying political interactions between people in both new and traditional media. Therefore, there has been a spate of recent research that either relies on, or pro- poses new methodology for, the classification of political ideology from text data. In this paper, we study the effectiveness of these techniques for classifying ideol- ogy in the context of US politics. We construct three different datasets of conser- vative and liberal English texts from (1) the congressional record, (2) prominent conservative and liberal media websites, and (3) conservative and liberal wikis, and apply text classification algorithms with a domain adaptation technique. Our results are surprisingly negative. We find that the cross-domain learning perfor- mance, benchmarking the ability to generalize from one of these datasets to an- other, is poor, even though the algorithms perform very well in within-dataset cross-validation tests. We provide evidence that the poor performance is due to differences in the concepts that generate the true labels across datasets, rather than to a failure of domain adaptation methods. Our results suggest the need for extreme caution in interpreting the results of machine learning methodologies for classification of political text across domains. The one exception to our strongly negative results is that the classification methods show some ability to generalize from the congressional record to media websites.

In particular, we are interested in how well measures of partisanship transfer across domains as well as the potential to rely upon measures of partisan intensity as a proxy for political ideology. We construct novel datasets of English texts from (1) the Congressional Record, (2) prominent conservative and liberal media websites, and (3) conservative and liberal wikis, and apply text classication algorithms to evaluate domain specicity via a domain adaptation technique. Surprisingly, we nd that the cross-domain learning performance, benchmarking the ability to generalize from one of these datasets to another, is in general poor, even though the algorithms perform very well in within-dataset cross-validation tests. While party aliation of legislators is not predictable based on models learned from other sources, we do nd some ability to predict the leanings of the media and crowdsourced websites based on models learned from the Congressional Record. This predictivity is dierent across topics, and itself a priori predictable based on within-topic cross-validation results.

Ross, Ph.D. Tiffiny A. Tung, Ph.D. Edward F. Fischer, Ph.D. Rogers P. Hall, Ph.D. To my wonderful spouse Lauren, who believed in me when I had given up and To my son Darwin, who doesn’t know a life in which his dad isn’t working on his dissertation ii ACKNOWLEDGEMENTS This dissertation would not have been possible without research grants from the National Science Foundation and a writing grant and mentorship from the Spencer Foundation. Crucial support came also from the Department of Anthropology at Vanderbilt University during the final year of writing, which enabled me to complete the task. In particular, I want to acknowledge the efforts of Tiffiny Tung in securing for me a fellowship that enabled me to move back to Nashville and focus on writing my dissertation. I am grateful to everyone who have contributed their time to help carry out this research, including the many fellow graduate students who helped me to complete interviews with students: Jeffrey Shenton, Werner Hertzog, Monte Talley, Danielle Kurin, Jonathan Attridge, Beck Conway, Lauren Stavish, John Saba and Kathryn DeTore. Furthermore, the willingness of people throughout Tennessee to talk to me was, of course, absolutely essential to its completion. I thank the participating school districts, the office staff and teachers who spent extra time on busy school days to make sure that the interviews could be done.
