Dielectric resonances in disordered media

Binary disordered systems are usually obtained by mixing two ingredients in variable proportions: conductor and insulator, or conductor and super-conductor. and are naturally modeled by regular bi-dimensional or tri-dimensional lattices, on which sites or bonds are chosen randomly with given probabilities. In this article, we calculate the impedance of the composite by two independent methods: the so-called spectral method, which diagonalises Kirchhoff's Laws via a Green function formalism, and the Exact Numerical Renormalization method (ENR). These methods are applied to mixtures of resistors and capacitors (R-C systems), simulating e.g. ionic conductor-insulator systems, and to composites consituted of resistive inductances and capacitors (LR-C systems), representing metal inclusions in a dielectric bulk. The frequency dependent impedances of the latter composites present very intricate structures in the vicinity of the percolation threshold. We analyse the LR-C behavior of compounds formed by the inclusion of small conducting clusters (``$n$-legged animals'') in a dielectric medium. We investigate in particular their absorption spectra who present a pattern of sharp lines at very specific frequencies of the incident electromagnetic field, the goal being to identify the signature of each animal. This enables us to make suggestions of how to build compounds with specific absorption or transmission properties in a given frequency domain.Comment: 10 pages, 6 figures, LaTeX document class EP

Evaluating Correspondence Between Preference Assessments Requiring Motor and Vocal Responses

Current practice is for reinforcers to be determined through systematic preference assessments prior to incorporating those items as reinforcers for behavior change programs. Historically, preference is typically determined by these assessments via a non-vocal response (i.e., subjects touch the item they prefer). It is possible in clinical settings, however, therapists simply ask an experienced learner what he or she “would like to work for” prior to commencing discrete trial training. It is unclear whether answers to these questions would align with subjects’ non-vocal responses in a more formal assessment. The current study compared subjects’ responses during two multiple-stimulus-without-replacement (MSWO) preference assessments and a “vocal nomination” assessment to determine if preferences were consistent across conditions. The first condition was a traditional MSWO with non-vocal responses, the second MSWO condition required a vocal choice response, and the third condition involved a vocal nomination, in which subjects were asked to vocally choose one item they “would like to work for.” Results were similar to previous research that modified procedures from the original preference assessments, including using briefer assessments and vocal nominations, might not be a sufficient method for determining preference. Correspondence between the highest preferred item in the MSWOs and vocal nomination matched in 62% percent of trials. Possible future directions are discussed and recommendations for further investigating how often procedures such as the vocal nomination are used within clinical practice are provided

An Analysis of and Guide to Tamora Pierce’s Protector of the Small Quartet as Compared to the Established Young Adult Fantasy Canon

Tamora Pierce’s work has been cited by many Young Adult fantasy authors as a major influence in recent years. Despite this, her work remains relatively obscure among librarians and readers of Young Adult literature. This paper examined one of Pierce’s Young Adult fantasy series, Protector of the Small, by comparing the series to existing works of Young Adult fantasy literature commonly accepted as classic or canonical literature. Among the comparative works were titles authored by C. S. Lewis, J. K. Rowling, and Philip Pullman. Comparison was character-focused, with emphasis on the representation of parents, other sympathetic adults, peers, and family units. Some comparison was also focused on the representation of antagonists in the selected works. The aim of the comparative analysis was to serve as a guide for librarians, teachers, and readers of Young Adult literature to better understand potential target audiences for the Protector of the Small quartet. It was found that target audiences for the series would likely seek or benefit from the Protector of the Small quartet’s inclusion of supportive parental and mentor figures, strong familial bonds, and supportive and communicative peers. Target audiences would also seek literature with nuanced antagonists capable of character growth. Most prominently, target audiences would seek Young Adult fantasy literature that addresses real-world issues and challenges for young women, including sexism, puberty, and reproductive healthcare

A Comparison of Pedagogical Approaches to Error Communication Training

Purpose: The purpose of this study was to compare the effectiveness of two different pedagogical approaches to error communication training. Background: The literature advocates full, transparent communication following a medical error. However, many barriers to such disclosure exist. A significant barrier is healthcare providers do not feel prepared for these difficult conversations. This can be particularly challenging in a pediatric setting when the conversation with a parent may be more demanding than similar conversations in the non-pediatric settings. Method: Individuals from three different professional groups were recruited; physicians, pharmacists, and nurses. A randomized controlled study was conducted to investigate whether the learning strategy used, interprofessional education (IPE) or self-study, influenced a team’s performance in a simulated error communication scenario. Results: The total mean score in a simulated error communication scenario was higher for the IPE group than the self-study group. This was not statistically significant; however, effect size would suggest a large estimation of magnitude between groups. Pre and post self-confidence scores identify that there was a significant difference in self-confidence following the education intervention for the IPE group but not for the self-study group. Overall satisfaction was higher in the IPE group Conclusion: It would appear that the IPE approach to error communication is more effective in terms of performance, self-reported confidence level, and participants overall satisfaction. Larger research studies are recommended for further investigation. A power calculation suggests a sample size of 17 teams per group (IPE and Self-study) for 80% power in future studies
