Solar X-ray spectrum reproduced in vacuum

Desired low energy X rays are produced by modifying commercial ion tubes and combining them with standard power supplies and control circuitry. These X rays have less deviation from the solar X ray spectrum in energy and intensity

bcp: An R Package for Performing a Bayesian Analysis of Change Point Problems

Barry and Hartigan (1993) propose a Bayesian analysis for change point problems. We provide a brief summary of selected work on change point problems, both preceding and following Barry and Hartigan. We outline Barry and Hartigan's approach and offer a new R package, pkgbcp (Erdman and Emerson 2007), implementing their analysis. We discuss two frequentist alternatives to the Bayesian analysis, the recursive circular binary segmentation algorithm (Olshen and Venkatraman 2004) and the dynamic programming algorithm of (Bai and Perron 2003). We illustrate the application of bcp with economic and microarray data from the literature.

Lunar nuclear power feasibility study

Based on review of literature and on limited examination of nuclear power systems now proposed for space applications, a nuclear fission reactor powered system should be seriously considered as the first large (order of 50 kWe or greater) power system to be placed on a lunar base. With relatively minor modifications, the major one being addition of a cooled side shield, the proposed 100 kWe product of the SP-100 Program could be adapted for use on a lunar base

Fluid Lines: Tracing Ryakuga-Shiki in Japan and France

Rykuga-shiki, or ‘abbreviated picture style,’ woodblock prints were first published and circulated widely in Edo period Japan (1615-1868). The style, created and popularized by Kitao Keisai Masayoshi (1764-1824) was not only admired and studied in its own time, but these Japanese ukiyo-e prints continued to influence style in the West. The work of artists in Paris, Henri de Toulouse-Lautrec (1864-1901) and Henri-Gabriel Ibels (1867-1936) present undeniable similarities (both in style and subject matter) with the ryakuga-shiki. Rarely studied and exhibited, the ryakuga-shiki are a part of the story of japonisme in France. This exhibition presents these prints in the context of work by Lautrec and Ibels for the first time, arguing that the French artists were indeed familiar on some level with and influenced by Keisai’s work. Beyond the obvious stylistic borrowings, the appropriation of Japanese prints styles and subject matter and their translation into French works has far more problematic cultural implications. By examining the legacy of the ryakuga-shiki beyond Japan, this exhibition and catalogue provide an opportunity to explore what it means to imitate and appropriate, collect, and value artwork from cultures that are not one’s own

The Influence of Corrective Feedback on Retrieval-induced Forgetting

Prior research has shown that testing can impair subsequent recall of nontested materials: an effect termed retrieval-induced forgetting. In the current study, I examined the effect of providing feedback during retrieval practice on the later recall of these nontested materials. In two experiments, I varied the type of feedback administered during retrieval practice (no feedback, immediate feedback, delayed feedback). Experiment 1 used cued recall as the final test, and Experiment 2 used recognition as the final test. As expected, providing immediate or delayed feedback (compared to no feedback) improved recall of tested materials. More importantly, Experiment 1 showed that providing immediate and delayed feedback did not increase the magnitude of retrieval-induced forgetting in a cued recall final test. Experiment 2 found that feedback reduced retrieval-induced forgetting in a recognition final test. From a practical perspective, these results indicate that feedback does not exacerbate retrieval-induced forgetting. This finding is encouraging for students and educators who use testing to help improve learning. From a theoretical perspective, these results provide support for the inhibitory account of retrieval-induced forgetting

The Gender Injustice of Abortion Laws

This commentary is a response to Katarzyna Sękowska-Kozłowska’s article on the treatment of criminal abortion laws as a form of sex discrimination under international human rights law through a study of the communications, Mellet v. Ireland and Whelan v. Ireland. The commentary offers a reading of these communications, and specifically the sex discrimination analysis premised on inequalities of treatment among women, as an engagement with the structural discrimination that characterises abortion laws, and asa radical vision for gender justice under international human rights law

Dumb and dumber: Stereotype perceptions at the intersection of race and athletic status

In this study, lists of traits typically associated with several groups of students were created using empirically supported methods. Specifically, these traits were grouped into a taxonomy based on the extent to which they were classified as being stereotypical for Black student-athletes, White student-athletes, Black non-athlete students, White non-athlete students, Black individuals, White individuals, athletes, and non-athletes. The purpose behind this study was to create lists of stereotypes associated with the above categories to address the methodological limitations of measures used previous research in sport psychology stereotypes. Results obtained using intraclass correlation measures of interrater agreement, chi-square and contingency coefficient analyses of forced-choice card sort data, and reliability analyses of stereotype ratings indicated support for a stereotype taxonomy encompassing each of these distinct groups. Additionally, the psychometrically based methods used in this study could provide a template for categorizing trait-adjectives about specific groups in more reliable and valid ways in many areas of psychology. The information from this specific study may be useful for future studies when determining applicable stereotypes to use for stereotype threat, perceptions of student-athletes, and perceptions of personality
