Scientific Utopia III: crowdsourcing science

Most scientific research is conducted by small teams of investigators who together formulate hypotheses, collect data, conduct analyses, and report novel findings. These teams operate independently as vertically integrated silos. Here we argue that scientific research that is horizontally distributed can provide substantial complementary value, aiming to maximize available resources, promote inclusiveness and transparency, and increase rigor and reliability. This alternative approach enables researchers to tackle ambitious projects that would not be possible under the standard model. Crowdsourced scientific initiatives vary in the degree of communication between project members from largely independent work curated by a coordination team to crowd collaboration on shared activities. The potential benefits and challenges of large-scale collaboration span the entire research process: ideation, study design, data collection, data analysis, reporting, and peer review. Complementing traditional small science with crowdsourced approaches can accelerate the progress of science and improve the quality of scientific research

Exploring the Relationships Between Pornography Consumption, Relationship Satisfaction, Relationship Beliefs, and Masculinity

Pornography is widely available and consumed in the United States and worldwide. Despite pornography’s wide spread use and expansions since the advent of the Internet, the psychosocial problems related to its use are not fully delineated. Previous studies have explored the relationship between pornography consumption and psychosocial variables such as sexual and physical violence against women, misogynistic beliefs, sexual callousness, acceptance of rape myths, and other problematic sexual beliefs and behaviors. Fewer studies have explored pornography use and its impact on relationship variables such as relationship satisfaction and beliefs about relational constructs such as intimacy, passion, and equality/independence. Furthermore, there are limited studies on how pornography consumption relates to constructs such as masculinity and body satisfaction among male users. The current study aimed to explore the relationship between these constructs, as well as further delineate pornography consumption by examining frequency, duration, method, subgenre, and perceived harm. One hundred fifty-six males were recruited from various northeastern universities and through online advertisements. Results demonstrated a significant negative relationship between pornography consumption and relationship satisfaction. Alternatively, body dissatisfaction and masculinity did not relate to pornography use or relationship satisfaction. Exploratory analysis indicated that pornography consumption was not related to perceived harm or opinions about intimacy, passion, or equality/independence. Research and clinical implications of the findings and future directions are discussed

Measuring the Importance of User-Generated Content to Search Engines

Search engines are some of the most popular and profitable intelligent technologies in existence. Recent research, however, has suggested that search engines may be surprisingly dependent on user-created content like Wikipedia articles to address user information needs. In this paper, we perform a rigorous audit of the extent to which Google leverages Wikipedia and other user-generated content to respond to queries. Analyzing results for six types of important queries (e.g. most popular, trending, expensive advertising), we observe that Wikipedia appears in over 80% of results pages for some query types and is by far the most prevalent individual content source across all query types. More generally, our results provide empirical information to inform a nascent but rapidly-growing debate surrounding a highly-consequential question: Do users provide enough value to intelligent technologies that they should receive more of the economic benefits from intelligent technologies?Comment: This version includes a bibliography entry that was missing from the first version of the text due to a processing error.

Her Life Depends On It: Sport, Physical Activity and the Health and Well-Being of American Girls

This report is a comprehensive compendium of research that points to physical activity and sport as fundamental solutions for many of the serious health and social problems faced by American girls. An appreciable mass of evidence-based knowledge about girls' involvement with sport and physical activity has been generated during the last decade. The amount and quality of this research are uneven and varied. For example, a good deal of research examines the associations between physical activity and risk for coronary heart disease, but studies that focus on risk for Alzheimer's disease are just beginning to issue. Researchers have verified links between high school athletic participation and teen pregnancy prevention, although more longitudinal research is needed to thoroughly confirm the connections. Overall, however, this report shows that the current state of knowledge on the relationship of physical activity to the health and social needs of American girls warrants the serious attention of public health officials, educators and sport leaders

A Public Voice for Youth: The Audience Problem in Digital Media and Civic Education

Part of the Volume on Civic Life Online: Learning How Digital Media Can Engage Youth.Students should have opportunities to create digital media in schools. This is a promising way to enhance their "civic engagement," which comprises political activism, deliberation, problem-solving, and participation in shaping a culture. All these forms of civic engagement require the effective use of a "public voice," which should be taught as part of digital media education. To provide digital media courses that teach civic engagement will mean overcoming several challenges, including a lack of time, funding, and training. An additional problem is especially relevant to the question of public voice. Students must find appropriate audiences for their work in a crowded media environment dominated by commercial products. The chapter concludes with strategies for building audiences, the most difficult but promising of which is to turn adolescents' offline communities -- especially high schools -- into more genuine communities

A new front in the history wars? Responding to Rubenhold’s feminist revision of the Ripper

Hallie Rubenhold’s The Five: The Untold Lives of the Women Killed By Jack the Ripper has drawn the criticism of the community of amateur sleuths dubbed ‘Ripperologists’ for its revisionist perspective, which claims that the canonical five victims of Jack the Ripper were not all sex workers. Rubenhold’s victim-centred approach has opened a new front in the history wars, as Ripperologists accuse her of historical denialism in pursuit of a feminist agenda. This article assesses Rubenhold’s methods, and her contribution to historical criminology, as well as considering why dominant historical narratives of crime prove so resistant to reinterpretation

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Latin American Online Animation: General Overview of its Contextual Conditions and Analysis of its Formal Traits.

The Latin American children of the late 1990s and 2000s grew up watching cartoons, just like those decades before; however, for the first time, many of these cartoons were being made by them. That was only the beginning… Benefiting from new digital animation technology and Internet availability as much as from a renewed sense of what cartoons were and for whom, online animation became one of the earliest and most popular forms of online media in Latin America and the world. And yet, their popularity is relatively confined to the Internet and their academic study remains scarce. This thesis aims to remediate this absence and to provide a base from which to give a better account of Latin American online animation. In doing so, it can improve our understanding of other online media’s connection with socio-economic, technological, ideological, and aesthetic imperatives. I highlight the role of economic class and cultural imperialism in online animation’s aesthetic and contents, consider the role of cable networks in both shaping these tastes and offering a precedent for online platforms like YouTube, and review the technological limitations leading to an online animation vernacular (regional and global). I focus on this vernacular’s formal traits as a necessary first step to approach online animation and potentially other media. Ultimately, I provide a socio-economic and techno-historical context for Latin American online animation’s visual culture and its media and geo-cultural specificity. This research is all the more necessary in the face of the impermanence of online media
