Level Curves of the Angle Function of a Positive Definite Symmetric Matrix

Level Curves of the Angle Function of a Positive Definite Symmetric Matrix

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Bajracharya, Neeraj
Description: Given a real N by N matrix A, write p(A) for the maximum angle by which A rotates any unit vector. Suppose that A and B are positive definite symmetric (PDS) N by N matrices. Then their Jordan product {A, B} := AB + BA is also symmetric, but not necessarily positive definite. If p(A) + p(B) is obtuse, then there exists a special orthogonal matrix S such that {A, SBS^(-1)} is indefinite. Of course, if A and B commute, then {A, B} is positive definite. Our work grows from the following question: if A and B are commuting positive definite symmetric matrices such that p(A) + p(B) is obtuse, what is the minimal p(S) such that {A, SBS^(-1)} indefinite? In this dissertation we will describe the level curves of the angle function mapping a unit vector x to the angle between x and Ax for a 3 by 3 PDS matrix A, and discuss their interaction with those of a second such matrix.

Levels of Psychological Health Related to the Cattell Sixteen Personality Factor Test

Date: June 1964
Creator: Bonney, Lewis A.
Description: The purpose of the present study is to develop an operationally defined standard of psychological health which will be proposed as: 1) one of the goals of psychotherapy; 2) a device for aiding in the evaluation of psychotherapy, and 3) a tool for screening those individuals in the general population who are in need of counseling in order to maintain their mental health.

Levels of Questioning Used by Student Teachers and its Effect on Pupil Achievement and Critical Thinking Ability

Levels of Questioning Used by Student Teachers and its Effect on Pupil Achievement and Critical Thinking Ability

Date: August 1972
Creator: Beseda, Charles Garrett, 1929-
Description: The purposes of this study were: 1. To determine the effect of levels of questioning used on secondary public school students in social studies, as measured by (a) their achievement scores, and (b) their critical thinking ability; 2. To determine the effect of feedback to student teachers on their patterns of asking convergent and divergent questions, as measured by coding frequencies of each type on an Observation Schedule and Record form? 3. To draw conclusions from the findings--and develop implications concerning levels of questioning used by teachers and the use of feedback from college supervisors to student teachers.

Levels of resourcefulness and motivation as they relate to sales force success: An examination of correlates using the hope theory.

Levels of resourcefulness and motivation as they relate to sales force success: An examination of correlates using the hope theory.

Date: December 2002
Creator: Pool, Patricia W.
Description: This study sought to determine whether a relationship existed between individual salesperson's levels of goal-directed cognition and motivation and their professional success as determined by the percentage of sales goals achieved. Salespersons represented two companies with national sales forces: one from the financial services industry and one from the apparel manufacturing industry. Both groups of salespeople were responsible for complex selling tasks. The skill sets for these professionals included high levels of communication skills, extensive product knowledge, and competitive market knowledge. Survey research, both paper and pencil and online, was conducted using the Hope Scale developed by C. R. Snyder and associates (1991). Hope is defined as a two-dimensional construct of goal-directed thinking: resourcefulness, thoughtful planning to overcome obstacles to goals, and motivation, cognition to sustain momentum toward goal achievement. Theoretically, upon assessing salespersons' Hope scores, organizations would be better prepared to assist those with low Hope Scale Scores (HSS) in one of the two areas. Those with low resourcefulness scores could be trained in cognitive techniques to overcome obstacles to goal achievement. Those with low motivational scores would be identified for further analysis, from a developmental perspective, to better determine what personally initiates and sustains motivation to attain their ...

Leveraging the Landscape

Leveraging the Landscape

Date: November 2012
Creator: Peters-Stanley, Molly; Hamilton, Katherine & Yin, Daphne
Description: Over the last three years, projects that address the relationships between carbon and forests have moved from the sidelines of international climate action to center field. Forestry’s recent advancements are the product of decades of ongoing collaboration among market and environmental experts seeking to strike an ideal balance between forestry projects’ market risks and shared benefits. Market dynamics in 2011 demonstrated that these efforts have never been more pivotal, or complex, as forest carbon projects mature – and find themselves positioned squarely in the midst of some of today’s most challenging policy debates. This year, a record number of forest project developers and secondary market suppliers from around the world shared data about their projects and transactions. This third annual State of the Forest Carbon Markets tracks, reports, and analyzes trends in these responses. This information is primarily based on data collected from respondents to Ecosystem Marketplace’s 2011 forest carbon project developer’s survey, combined with data from the 2012 State of the Voluntary Carbon Markets report. The data and analysis that follow cover forest carbon activity in compliance carbon markets – including the Kyoto Protocol’s Clean Development Mechanism (CDM), the New Zealand Emissions Trading Scheme (NZ ETS), the New South ...

The Lexicographer's Daughter: A Memoir

The Lexicographer's Daughter: A Memoir

Access: Use of this item is restricted to the UNT Community.
Date: May 2011
Creator: Lovell, Bonnie Alice
Description: This creative nonfiction dissertation is a memoir of the author's search for the somewhat mysterious hidden past of her father, the lexicographer Charles J. Lovell, who died in 1960, when the author was nine. Her father's early death left the author with many unanswered questions about his past and his family and so she undertakes a search to answer, if possible, some of those questions. Her search takes her to Portland, Maine; New Bedford, Massachusetts; and Pasadena, California, where she tries to discover the facts and uncover the forces that shaped her father's life. Along the way, she realizes how profoundly his death affected and shaped her own life, contributing to the theme of loss that pervades the memoir. In addition, she begins to realize how much her mother, Dixie Hefley Lovell, whose significance she previously overlooked, shaped her life. Ultimately, she comes to understand and accept that some of her questions are unanswerable.
