These lectures are divided into two main parts. In the first part we give an introduction to the theory of Kac-Moody algebras directed towards physicists. In particular, we describe the subclasses of affine and Lorentzian Kac-Moody algebras in detail. Our treatment focuses on the Chevalley-Serre presentation, and emphasizes the importance of the Weyl group. We illustrate the basic theory with s...

Teachers’ Perceptions of School Violence: A Case Study by Jessica Anderson Doctoral Study Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Education Walden University December 2016 Abstract School violence has gained attention in recent years with the rise of aggressive behavior in schools across the United States. With increased understanding of this problem, sc...

This paper employs non-parametric specification tests developed in Hong and Li (2005) to evaluate several one-factor reduced-form credit risk models for actual default intensities. Using estimates for actual default probabilities provided by Moody’s KMV from 1994 to 2005 for 106 U.S. firms in seven industry groups, we strongly reject popular univariate affine model specifications. As a good com...

Representation theory of affine Kac-Moody algebras at the critical level contains many intricate structures, in particular, the hamiltonian structures of the KdV and modified KdV hierarchies and the Miura transformation between them. In this talk I will describe these structures and their deformations which will lead us to the deformed Virasoro and W–algebras and the integrable hierarchies asso...

BACKGROUND Although studies have outlined the benefit of diversity in academic medicine, the number of underrepresented minority (URM) faculty remains low. In 1998, University of California, San Diego (UCSD) School of Medicine with the Hispanic Center of Excellence began a formalized proactive faculty development program. Over the past 10 years, recruitment and retention of URM junior faculty h...

The exposure of outdoor workers to solar ultraviolet radiation (UVR) has been known for some time. Measurements of erythemally weighted UVR are usually related to days of exposure and to the anatomical distribution of UVR on the human body. The aim of this research is to describe the UVR exposure of workers during a strawberry production cycle in order to assess the UVR hazard and to identify t...

The objective of this pilot study was to investigate the use of and satisfaction with a chronic obstructive pulmonary disease (COPD) telehealth program applied in both primary and secondary care. The program consisted of four modules: 1) activity coach for ambulant activity monitoring and real-time coaching of daily activity behavior, 2) web-based exercise program for home exercising, 3) self-m...

Asset correlation is a critical driver in modeling portfolio credit risk. Despite its importance, there have been few studies on the empirical relationship between asset correlation and subsequently realized default correlation, and portfolio credit risk. This three three-way relationship is the focus of our study using U.S. public firm default data from 1981 to 2006. We find the magnitude of d...

Variation in tissue sample preparation leads to variation across the Transcriptome not just between experiments but to between individual microarrays. Normalisation is essential before data from different arrays can be compared. Quantile normalisation can be used to force data from a single GeneChip to take a given distribution. However quantile normalisation can be blind to the consistent spat...

The provision of drug information (DI) is among the fundamental professional responsibilities of all pharmacists. Recent practice trends, including increased provision of medication therapy management services and efforts to obtain provider status, have placed pharmacists in increasingly complex patient-care roles and necessitated a higher level of competence by all pharmacists in meeting DI ne...
