Synthesis of cubic boron nitride thin films on silicon substrate using electron beam evaporation.

Description: Cubic boron nitride (cBN) synthesis has gained lot of interest during the past decade as it offers outstanding physical and chemical properties like high hardness, high wear resistance, and chemical inertness. Despite of their excellent properties, every application of cBN is hindered by high compressive stresses and poor adhesion. The cost of equipment is also high in almost all the techniques used so far. This thesis deals with the synthesis of cubic phase of boron nitride on Si (100) wafers … more

Transfer of Mand Topographies to Tact Relations and Vice Versa in Two Vocal-Verbal Children with Autism

Description: Skinner (1957) suggested that verbal responses learned as mands are not necessarily emitted in tact relations and vice versa. Previous empirical research has found that newly acquired mands and tacts can be functionally independent. The present study investigated 1) whether novel responses taught in mand relations would be emitted as tacts when opportunity for tacting was presented; 2) whether novel responses taught in tact relations would be emitted as mands when opportunity for manding was pr… more

Use of Fading Procedures and Positive Reinforcement to Increase Consumption of Non-Preferred Food in a Child with Autism

Description: Traditionally children with developmental disabilities who develop feeding issues can be at great risk for malnutrition. Failure to eat adequate amounts of food and/or insistence on eating a limited range of foods can be detrimental to a child's health and can lead to other behavioral difficulties. Feeding problems are difficult to treat because high levels of physical prompting can quickly create an aversion to eating as well as cause stress for both parents and children. Behavioral problems t… more

Utilization of Corridor Habitat by White-tailed Deer (Odocoileus virginianus) in Denton County, Texas

Description: White-tailed deer (Odocoileus virginianus) (N=15) movements were determined with use of radio telemetry techniques to determine the utilization of corridor habitat on the Lake Ray Roberts Greenbelt Corridor (RRGC) in north central Texas. Home ranges were calculated using three estimation types. Male white-tailed deer tend to have home ranges twice that of female home ranges. Seasonal home ranges were largest during spring (Feb. - April) and fall (Aug. - Oct.) seasons. Males had greater seasonal… more

Voice and Genre in Beethoven's Deux Grandes Sonates pour le Clavecin ou Piano-Forte avec un Violoncelle obligé, Op. 5

Description: This paper examines the generic aspect of Beethoven's Opus 5 Cello Sonatas (1796) from structuralist and post-structuralist perspectives, and explores the works from these viewpoints in order to gain insights into how the sonatas function as autonomous musical texts rather than historiographic documents of Beethoven's biography or transitional contributions in the development of the genre of the solo sonata as it was later cultivated. The insights offered by these perspectives argue for a recon… more

Wayfinding tools in public library buildings: A multiple case study.

Description: Wayfinding is the process of using one or more tools to move from one location to another in order to accomplish a task or to achieve a goal. This qualitative study explores the process of wayfinding as it applies to locating information in a public library. A group of volunteers were asked to find a selection of items in three types of libraries-traditional, contemporary, and modern. The retrieval process was timed and the reactions of the volunteers were recorded, documented, and analyzed. Th… more

Wild Practices: Teaching the Value of Wildness

Description: The notion of wildness as a concept that is essentially intractable to definition has profound linguistic and ethical implications for wilderness preservation and environmental education. A survey of the ways in which wilderness value is expressed through language reveals much confusion and repression regarding our understanding of the autonomy of nature. By framing discussions of wilderness through fact-driven language games, the value of the wild autonomy in nature becomes ineffable. In remo… more
