Description: In the new generation of artists emerging in South Africa, Alexander Johnson is considered the most prolific young composer of his day. In a recent review in the Pretoria News, Johnson has been praised by eminent critic Paul Boekkooi as a composer who has “an ear for the exotic and knows exactly how to bring it off....” He continued by noting that his music is “mentally engrossing, pleasurable to the senses and seems refreshingly free from dogmatic formulas." Johnson writes for musicians and the general public to equal satisfaction. His accessible compositions and catching use of melodic materials have made his writings very popular both in South Africa and abroad. During his residency in Belgrade in 1993-94, Johnson met Croatian pianist Dorian Leljak. Impressed with Johnson's compositional ideas and output, Leljak commissioned a work from Johnson for piano and orchestra. The result was the Niš Concerto, which Johnson completed in April 1994. The world premiere took place on June 23, 1994 with the Niš Philharmonic Orchestra conducted by Anatoli Nowiestski with Dorian Leljak as soloist. The Niš Concerto received its South African premiere in 1995 during a simultaneous celebration for “Europe Day” and the new democracy of the Republic of ...

A national analysis of faculty salary and benefits in public community colleges, academic year 2003-2004.

A national analysis of faculty salary and benefits in public community colleges, academic year 2003-2004.

Date: December 2006
Creator: Maldonado, José F.
Description: This study provides a detailed description of full-time faculty salary and fringe benefits in US public community colleges by state and by 2005 Carnegie basic classification type for the academic year 2003-2004. This classification is used to analyze data from the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS). Further analysis clusters states into the following groupings: states with/without collective bargaining agreements, states with/without local appropriations, large megastates versus nonmegastates (using the methodology developed by Grapevine at Illinois State University), and the impact of California on the nation's salaries and fringe benefits. The analysis showed high level of variation of salaries paid by the type of community college (rural, suburban, and urban serving) in the US. The nation's average salary for full-time faculty was $52,598. Rural serving small institutions faculty salary was $18,754 or 45 % less than the nation's average. Salaries in colleges with collective bargaining agreement were higher than in colleges without collective bargaining agreements. Faculty teaching in suburban serving colleges with local taxation had the highest salaries, $61,822 within colleges with access to local support. Suburban serving multiple colleges in megastates had the highest faculty salary average, $64,540 as compared to $42,263 for rural ...

The Effects of Parenting Stress and Academic Self-Concept on Reading Ability in a Clinic Referral Sample

The Effects of Parenting Stress and Academic Self-Concept on Reading Ability in a Clinic Referral Sample

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Maldonado, Michele L.
Description: This study investigated the relationships among the variables of parenting stress, academic self-concept, and reading ability. The purpose of this study was to determine whether parenting stress and academic self-concept contributed to the child's reading ability. Two hypotheses were investigated in an effort to accomplish this purpose. The subjects used in this study were forty-nine children and their primary caretakers referred to The Child and Family Resource Center, The University of North Texas, Denton, Texas, during the academic years of 1994 through 1999. Subjects ranged in age from seven to eighteen years of age. Academically, the subjects ranged from first graders through eleventh graders. All subjects lived in and attended schools in Denton County or neighboring counties. Parental employment ranged from unskilled laborers to medical doctors. The participating families included biological, step, adoptive, single, and divorced families. Abidin's Parenting Stress Index was used to measure parental stress experienced by the primary caretaker. The Intellectual and School Status cluster of the Piers-Harris Children's Self-Concept Scale was used to measure the child's academic self-concept and the Woodcock Reading Mastery Test-Revised provided a measure of the child's reading ability. Test scores were obtained following a review of The Child and Family Resource Center's ...

Strategic Path to Fiscal Sustainability: Revenue Diversification and the Use of Debt By Us Municipal Governments

Strategic Path to Fiscal Sustainability: Revenue Diversification and the Use of Debt By Us Municipal Governments

Date: August 2012
Creator: Maleckaite, Vaida
Description: This work explores the relationship between municipal government debt and revenue diversification using a prism of institutional and fiscal interactions, concentrating on revenue fungibility effects over time and on the role of state-imposed constraints. A diversified revenue structure tends to stabilize revenue levels by balancing income-elastic and inelastic revenue sources. The impact of such diversity has been the subject of much research on expenditure and service levels among state and local governments. Considerably less research has been conducted on its potential relationship with debt, although capital financing is a necessary and often-utilized mechanism for funding capital and operational spending for local governments. Since it is well known that debt payments are fixed in the short run, they require sufficient revenue adequacy through economic highs and lows. It is thus argued that local governments with more diversified revenue structures are better able to utilize debt financing since revenue diversity mitigates the risk of borrowing by providing for greater fiscal predictability in the long run. This hypothesis is tested on two samples - a large sample of cities in Massachusetts from 2000 through 2009, as well as a cross-state sample, encompassing the cities from the majority of U.S. states. The findings of ...

Psychological Stress Reactivity and Recovery: The Role of Cognitive Appraisals, Ethnicity and Sex

Psychological Stress Reactivity and Recovery: The Role of Cognitive Appraisals, Ethnicity and Sex

Date: December 2009
Creator: Malhotra, Damini
Description: The aim of this research was to investigate the role of sex, ethnicity and cognitive appraisals, separately and in combination, on the physiological stress response. One hundred and eight undergraduate students from two North Texas universities participated in the study. They were subjected to a laboratory stressor and heart rate, peripheral temperature and cortisol levels were measured pre-, during-, and post- stressor. Perceived stress and cognitive appraisals were measured via self-report. Multivariate analysis of variance tests were conducted to analyze the main and interaction effects during baseline, reactivity and post-stress recovery. Results indicated some significant main effects for sex and ethnicity but no consistent pattern of results or interactions among variables were revealed. The study's implications and areas of future research are discussed.

End of Insertion Detection in Colonoscopy Videos

End of Insertion Detection in Colonoscopy Videos

Date: August 2009
Creator: Malik, Avnish Rajbal
Description: Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to ...
