Evaluation of the optical conductivity tensor in terms of contour integrations

For the case of finite life-time broadening the standard Kubo-formula for the optical conductivity tensor is rederived in terms of Green's functions by using contour integrations, whereby finite temperatures are accounted for by using the Fermi-Dirac distribution function. For zero life-time broadening, the present formalism is related to expressions well-known in the literature. Numerical aspects of how to calculate the corresponding contour integrals are also outlined.Comment: 8 pages, Latex + 2 figure (Encapsulated Postscript

Examination of a Parent-Assisted, Friendship-Building Program for Adolescents With ADHD

Objective: Youth with ADHD experience significant impairment in peer functioning. Based on recommendations from the literature, the current pilot study examined the effectiveness of a parent-assisted, friendship-building program at establishing mutual friendships and improving peer relationships in adolescents with ADHD. Method: Participants included 20 adolescents with ADHD (ages 11-16 years) and their parent(s). Families completed the Program for the Evaluation and Enrichment of Relational Skills (PEERS). Measures of friendship quality, social knowledge, social self-efficacy, get-togethers, and peer conflict were completed at baseline and post-treatment. At post-treatment, participants also reported on the initiation of a new friendship. Results: Baseline to post-treatment differences were examined using paired-samples t tests. The majority of participants reported the initiation of a new friendship at post-treatment. Adolescents also demonstrated significantly improved social knowledge and increased get-togethers. Effect sizes were large. Conclusion: Following participation in PEERS, adolescents improved in several peer functioning domains and many initiated new friendships

Maternal Functioning Differences Based on ADHD Subtype

Objective: Maternal functioning differences in parenting stress, parental efficacy, and parenting behaviors were examined for mothers of children with ADHD. Method: Participants included 29 mothers of children with ADHD, Predominantly Inattentive Type (ADHD-I) and 38 mothers of children with ADHD, Predominantly Hyperactive-Impulsive or Combined Type (ADHD-HI/C). Results: Findings suggest that mothers of children with ADHD-HI/C reported significantly greater parenting stress and engaged in more negative parenting behaviors than mothers of children with ADHD-I. Conclusion: This study suggests that tailoring behavioral parent training based on ADHD subtype may be particularly helpful for parents of children with ADHD-HI/C

Immaculate Defamation: The Case of the Alton Telegraph

At the confluence of three major rivers, Madison County, Illinois, was also the intersection of the nation’s struggle for a free press and the right of access to appellate review in the historic case of the Alton Telegraph. The newspaper, which helps perpetuate the memory of Elijah Lovejoy, the first martyr to the cause of a free press, found itself on the losing side of the largest judgment for defamation in U.S. history as a result of a story that was never published in the paper—a case of immaculate defamation. Because it could not afford to post an appeal bond of that magnitude, one of the oldest family-owned newspapers in the country was forced to file for bankruptcy to protect its viability as a going concern. Attention must be paid to a case in which plaintiff’s counsel earns a place in the Guinness Book of World Records and his adversary is honored for distinction in the defense of a free press and the people’s right to know. Notwithstanding subsequent reform of the supersedeas bond process, the inability to appeal a defamation award for lack of sufficient resources to secure a bond still presents an existential threat to all but the largest media companies. The appeal bond process thus has a chilling effect on organizations engaged in newsgathering and dissemination, abridging freedoms protected by the First Amendment. This Article proposes a re-imagination of the appeal bond to accommodate the legitimate interests of the judgment creditor while protecting a media defendant’s constitutional right to appeal

Electrical transport properties of bulk Nic_{c}Fe1−c_{1-c} alloys and related spin-valve systems

Within the Kubo-Greenwood formalism we use the fully relativistic, spin-polarized, screened Korringa-Kohn-Rostoker method together with the coherent-potential approximation for layered systems to calculate the resistivity for the permalloy series Ni$_{c}$Fe$_{1-c}$. We are able to reproduce the variation of the resistivity across the entire series; notably the discontinuous behavior in the vicinity of the structural phase transition from bcc to fcc. The absolute values for the resistivity are within a factor of two of the experimental data. Also the giant magnetoresistance of a series of permalloy-based spin-valve structures is estimated; we are able to reproduce the trends and values observed on prototypical spin-valve structures.Comment: 6 pages, ReVTeX + 4 figures (Encapsulated Postscript), submitted to PR

Tools of Ignorance: An Appraisal of Deficiency Judgments

While achieving success as a major league catcher, Mike Matheny was preparing for a post-baseball career in real estate development. He could not have picked a worse time to pursue his aspiration. Matheny lost his accumulated savings and his family’s home after being held personally liable for a $4.2 million deficiency judgment following foreclosure of property he was unable to develop or market during the Great Recession. Matheny’s failure to succeed in real estate was the proximate cause of his return to baseball as manager of the St. Louis Cardinals. Matheny’s story provides the backdrop for examining the methods by which deficiency judgments are calculated. The traditional common law approach has been criticized as unjust and overdue for reform. The most widely adopted variation, known as the “fair value” method, is hollow at its core. It provides no meaningful guidance to triers of fact charged with adjudicating value. This Article proposes a re-imagination of the method of calculating deficiency judgments based on experience in transactional practice and alternative dispute resolution. It seeks to accommodate the interests of borrowers and lenders, and the public interest in judicial efficiency and access to affordable credit
