Abnormalities of the long flash ERG in congenital stationary night blindness of the Schubert-Bornschein type
No full textWe investigated abnormalities of the retinal cone ON- and OFF-pathways in 24 males with Schubert-Bornschein congenital stationary night blindness (CSNB). Substantial differences were found between both CSNB types. In incomplete type, a-, b- and d-waves were reduced and delayed, whereas in complete type only the b-wave showed significant changes. Oscillatory potentials (OPs) were not discernible from noise in incomplete CSNB and showed significant peak alterations of the ON-OPs only in complete CSNB. In the complete CSNB type, the ON pathway appeared to be mainly affected. In the incomplete CSNB form marked involvement of both the ON and the OFF pathways was noted. (C) 2002 Elsevier Science Ltd.

Gamer Talk
No full textA qualitative case study of student game play is presented, describing how game player communication becomes increasingly complex, efficient, and impenetrable by those who have not actively played the game. Transcripts of gathered video tape reveal how student ‘gamer talk’ became increasingly implicit, using terminology provided by the game and their shared context of playing the game. Over time, communication among game player group members generally became more efficient and less penetrable by members outside the group (such as new players), as players engaged in culture-building activities around their shared context. However, players occasionally became more explicit in their communication when grounding was required to reach shared meaning, such as in instances where players disagreed on the purpose of a particular game feature or strategy. Finally, implications are offered to suggest ways in which gamer cultures can be made more accessible to game designers and those guiding classroom interactions.</jats:p

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Development and validation of the Female Gamer Stereotypes Scale.
No full textFemale gamers belong to a stereotyped social group. The stereotypes associated with female gamers may be associated with issues such as sexism and gender discrimination in the gaming community. However, few tools exist to properly assess the complex nature of the stereotypes held about this group. The present paper describes the development and validation of the Female Gamer Stereotypes Scale (FGSS), which offers a multifaceted measure of the stereotypical beliefs toward women who play video games. Five first-order FGSS factors have emerged and been consistent with data across three studies. The five dimensions target areas of stereotypes toward female gamers such as their lack of femininity, lack of sociability, weak gaming competence, reliance on men in gaming, and gaming preferences. A total of 1266 individuals from both a student sample and large national U.S. samples participated the studies. In the first study, a large pool of potential scale items was generated. In study 2 and 3, the five-factor, 20-item FGSS was developed and validated through five subsamples, including gamers, male gamers, female gamers, non-gamers, and the general population. Across all subsamples, the FGSS demonstrated excellent content and construct validity. Implications of results and recommendations for future studies are discussed.This is a pre-copyedited, author-produced version of an article accepted for publication at Psychology of Popular Media.

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
