Exact Multi-Restricted Schur Polynomial Correlators
We derive a product rule satisfied by restricted Schur polynomials. We focus
mostly on the case that the restricted Schur polynomial is built using two
matrices, although our analysis easily extends to more than two matrices. This
product rule allows us to compute exact multi-point correlation functions of
restricted Schur polynomials, in the free field theory limit. As an example of
the use of our formulas, we compute two point functions of certain single trace
operators built using two matrices and three point functions of certain
restricted Schur polynomials, exactly, in the free field theory limit. Our
results suggest that gravitons become strongly coupled at sufficiently high
energy, while the restricted Schur polynomials for totally antisymmetric
representations remain weakly interacting at these energies. This is in perfect
accord with the half-BPS (single matrix) results of hep-th/0512312. Finally, by
studying the interaction of two restricted Schur polynomials we suggest a
physical interpretation for the labels of the restricted Schur polynomial: the
composite operator is constructed from the half BPS

Cross-sectional study of risky substance use by injured emergency department patients
INTRODUCTION: Survey data regarding the prevalence of risky substance use in the emergency department (ED) is not consistent. The objective of this study was to identify the prevalence of risky substance use among injured ED patients based on the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST v3.0). A secondary objective was to report on the feasibility of administering the ASSIST to this population, based on the time to conduct screening. METHODS: This cross-sectional study used screening data from a randomized controlled trial. Injured ED patients completed the ASSIST on a tablet computer, and an ASSIST score was computed that indicated the need for a brief or intensive treatment intervention (risky use) for alcohol and other substances. For a subsample, data on time to complete each step of screening was recorded. RESULTS: Between July 2010 and March 2013, 5,695 patients completed the ASSIST. Most (92%) reported lifetime use of at least one substance and 51% reported current risky use of at least one substance. Mean time to complete the ASSIST was 5.4 minutes and screening was considered feasible even when paused for clinical care to proceed. CONCLUSION: Estimates of risky substance use based on the ASSIST in our large sample of injured ED patients were higher than previously reported in other studies of ED patients, possibly due to the current focus on an injured population. In addition, it was feasible to administer the ASSIST to patients in the course of their clinical care.Published versio
An Organization’s Ability to Improve Outsourcing Outcomes in Information Technology Outsourcing Initiatives by Increasing Organizational Knowledge: A Case Study
The problem addressed in this study was the literature gap regarding how internal organizational knowledge can be increased effectively within outsourcing projects. The study was a qualitative social constructionist case study composed of senior technology leaders. The purpose this study addressed was to understand the current structure of technical outsourcing contracts and how future contracts could be structured to address the problem of this study. The research incorporated how a reconceptualized absorptive capacity model, sociocognitive theory, and digital leadership mindsets could improve knowledge transfer outcomes between a vendor and client. Research shows that increasing an organization’s knowledge during an outsourcing project can lead to increased organizational innovation capacity and improve the output and quality of products. The qualitative semistructured interview data were codified manually using transcribed data with NVivo 12 software for depicting patterns and themes. The study findings indicated that corporate learning programs lacked the necessary rigor to prepare the organization effectively before and after an outsourcing engagement in terms of preparing associates with the technical knowledge transfer necessary to lessen future vendor dependencies. Additionally, I found a lack of formalized language depicting learning and knowledge transfer deliverables in outsourcing contracts. The study’s primary conclusion centered on the importance of leaders incorporating a more digital mindset and a corporate learning program focused on a structured, continual strategic learning program. Additionally, the development and inclusion of formalized learning objectives, knowledge transfer, and stated deliverables in an outsource contract are vital
Judge over Jury: Florida\u27s Practice of Imposing Death over Life in Capital Cases
Where a jury and a trial judge reach contrary conclusions because the facts derive from conflicting evidence, or where they have struck a different balance between aggravating and mitigating circumstances which both have been given an opportunity to evaluate, the jury recommendation should be followed because that body has been assigned by history and statute the responsibility to discern truth and mete out justice. Given that the imposition of a death penalty “is not a mere counting process of X number of aggravating circumstances and Y number of mitigating circumstances, but rather a reasoned judgment . . . ,” both our Anglo-American jurisprudence and Florida\u27s death penalty statute favor the judgment of jurors over that of jurists.
[W]hen juries differ with the result at which the judge would have arrived, it is usually because they are serving some of the very purposes for which they were created and for which they are now employed
