Deaf students in mainstream colleges are withdrawing at an alarming rate. Approximately 70% of the 123,000 deaf students enrolled in 2,300 colleges across the United States will not persist until graduation. This qualitative study examined what factors in the academic and social environment are linked to deaf college students' perceptions...
Adolescent pregnancy is a major social problem which results in negative psychological, medical, developmental,
economic and educational consequences for both mother and child. A review of the literature examined psychological and sociocultural factors and negative consequences associated with adolescent pregnancy. There has been little research on age specific differences between...
The primary purpose of this study was to determine the work values of the emotionally disturbed adolescents and to compare these values with those indicated by adolescents
of the same age level from a regular public school. A secondary objective was to compare the work values of the age levels,...
In many areas of the developing world, the continued overexploiting forest resources has the potential to have significant detrimental impacts be placed on sustainable forest management (SFM) can help communities and organizations responsibly manage and utilize the remaining forests over the long term. Ethiopia’s forest lands provide tangible benefits from...
Individual supervision is a widely accepted practice in the counseling profession, yet the tasks and focus of individual supervision in an agency setting remain largely uninvestigated. The tasks and focus areas inherent to agency supervision are especially important to counselors, counselor educators, agency administrators, and licensing boards, all of whom...
Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...
FISHNET (Facilities Integrated in a Shared Habitat) is a communication subnet architecture utilizing a hybrid application of point-topoint and broadcast communications to achieve a high degree of network performance. This objective is achieved through utilizing a dual bus structure: a data bus and a control bus. The data bus consists...
This dissertation presents a dual-path 2-0 MASH (Multi-stAge-noise -SHaping) ADC with two verified digital corrections of DAC mismatch error and quantization noise leakage. By using these two techniques, the requirements for the analog circuits are greatly relaxed. The dual-path structure generates two outputs, one only composed of conversion errors, the...
Digital-to-analog converters (DACs) with wide dynamic range and high
linearity are required for high-end audio applications. A multi-bit delta sigma
audio DAC, using a novel gain-correction technique, is described in this thesis. For
widely varying on-chip RC time constant, the DAC gain can be accurately
controlled by the correction circuitry....
The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...
