Synthesis Of Novel Alkaloids Using Squaric Acid Esters, Peter S. Zehr Dec 2005

Synthesis Of Novel Alkaloids Using Squaric Acid Esters, Peter S. Zehr

Graduate Theses, Dissertations, and Problem Reports (ETD)

A novel route to cyclopenta[b]quinoline-1-ones and -ols has been developed. Substituted cyclopenta[b]quinolin-1-ones were prepared by thermal ring-expansion of substituted N-BOC protected 4-(2-aminophenylethynyl)-4-hydroxy-2-cyclobuten-1-ones forming the corresponding 2-aminophenylmethylidene substituted 4-cyclopentene-1,3-diones. Deprotection of the amine resulted in spontaneous condensation to give cyclopenta[b]quinolin-1-ones. Sodium borohydride reduction of these products produced cyclopenta[b]quinolin-1-ols. The key step in the sequence is a thermally induced ring-expansion of 4-(2-aminophenylethynyl)-4-hydroxy-2-cyclobuten-1-ones. Changing the amino protecting group had no effect on the ring size selectivity of the thermal ring expansion. The thermal ring expansion of the corresponding nitro derivative suggests that electron withdrawing substituents may alter the selectivity of the ring formation. …

Three Essays On Migration: Its Interaction With Regional Wage Differentials And Occupational Choice And Its Application In Different Discrete Choice Models, Christiadi Dec 2005

Three Essays On Migration: Its Interaction With Regional Wage Differentials And Occupational Choice And Its Application In Different Discrete Choice Models, Christiadi

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three essays that examine two important roles of migration, promoting regional wage convergence and increasing economic efficiency. The first essay is a survey of the migration and migration-related literatures, examining why migration and regional wage differentials can co-exist over time. The direct reason is that the classical assumptions leading to regional wage convergence are rarely fully applicable in the real world. This essay reveals various real-world conditions violating those assumptions and explains how they can either create or magnify regional wage differentials. The essay also reveals how the difficulty in distinguishing wage differentials from true wage …

The Influence Of Humanism On The Handwriting Of Michelangelo Buonarroti, Robert J. Tallaksen Dec 2005

The Influence Of Humanism On The Handwriting Of Michelangelo Buonarroti, Robert J. Tallaksen

Graduate Theses, Dissertations, and Problem Reports (ETD)

The handwriting of Michelangelo Buonarroti underwent a distinct and permanent change between 1497 and 1502. The handwriting of his early letters of 1496 and 1497 is merchantescha, the gothic cursive mercantile script which he would have learned at school. The later handwriting is cancellarescha, a humanistic cursive. It is present in letters, contracts, memoranda, records of accounts, and in annotations on drawings. Both scripts as written by Michelangelo are analyzed paleographically and are compared to examples from instructional writing books of the period. The impossibility of evolution from one script to the other is demonstrated through analysis of the scripts …

The Impact Of Points Of Impasse On Conflict Escalation During The Special Education Conflict Resolution Process, Deedra Jane Lundeen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Current literature reveals the disparity between the knowledge that strong parent-school partnerships are integral to planning and implementing educational programming for exceptional children, and the ability of parents and school personnel to identify and deescalate conflict when it occurs. Several studies acknowledged variables that helped build and maintain strong parent-school collaboration, and identified factors that escalated or de-escalated parent conflict. However, the research is sparse regarding factors that impact points of impasse on conflict escalation between parents and school districts during the special education conflict resolution process.

Assessing The Effectiveness Of Descriptive And Experimental Analyses To Identify Variables Influencing Problem Behavior In Domestic Dogs, Susan D. Kapla Dec 2005

Assessing The Effectiveness Of Descriptive And Experimental Analyses To Identify Variables Influencing Problem Behavior In Domestic Dogs, Susan D. Kapla

Graduate Theses, Dissertations, and Problem Reports (ETD)

Problem behavior in dogs is a concern for pet owners. Many contemporary approaches to intervention first involve a process of diagnosis and classification which is often structural in nature. An accurate diagnosis is considered essential for effective treatment, however, outcome data validating the efficacy of this procedure are dubious. The success of strategies used to assess and treat behavior problems that identify behavioral function in humans (functional assessment), however, suggests the potential utility of such techniques in the assessment and treatment of behavior problems in dogs. Therefore, two separate assessments were conducted to identify and manipulate variables affecting problem behavior …
