A Descriptive Study Of School-Based Intervention Teams In New York State, Sean Croft
A Descriptive Study Of School-Based Intervention Teams In New York State, Sean Croft
Theses
This study examined the current practices of school-based intervention teams (SBIT) in New York State. SBIT are designed to provide immediate assistance to students and teachers, to enhance the ability of teachers to serve difficult-to-teach students within regular education classrooms, and to reduce the number of inappropriate referrals to special education. A mail questionnaire (N=T74; return rate=43%) found that a majority of teams meet once a week, during school hours, and consist of about nine members. SBIT members favor teacher intuition and classroom performance over data-based progress monitoring in deterrnining the effectiveness of interventions. The lack of personnel to perform …

Eye Movements And Natural Tasks In An Extended Environment, Roxanne Canosa
Eye Movements And Natural Tasks In An Extended Environment, Roxanne Canosa
Theses
Eye movements can be thought of as a window onto pre-conscious thought. Patterns of visual fixations over time as well as space can reveal cognitive strategies that are not amenable to conscious control or verbalization. A spatial analysis of an eye movement trace usually emphasizes the role that eye movements have in moving the retinal image of an object of interest from the periphery to the fovea for closer inspection. It is generally believed that a sequence of fixations across a region of space builds up the perception of a high-resolution field of view everywhere. Recent studies have shown that …

Rhodium Trichloride Catalyzed Hydroboration Of 1-Octene: Unexpected Results, Anthony Sampognaro
Rhodium Trichloride Catalyzed Hydroboration Of 1-Octene: Unexpected Results, Anthony Sampognaro
Theses
Previous studies of the rhodium trichloride (RhCl3) catalyzed hydroboration of 1- octene showed a reversal of regiochemistry compared to the uncatalyzed reaction, and a complex mechanism was proposed to explain this phenomenon. Recent advances in analytical technique has revealed the presence of 4-octanol and 3-octanol. in addition to the expected 2-octanol and 1 -octanol products. The existence of these unexpected products has been attributed to the isomerization of 1-octene to internal isomers prior to normal hydroboration and oxidation, instead of the previously proposed mechanism. Initial kinetic studies indicated that the RI1CI3 catalyzed isomerization of 1-octene occurs too slowly to account …

Reduction Of Peak To Average Power Ratio In Ofdm And Ofdm-Cdma System, Jie Cheng
Reduction Of Peak To Average Power Ratio In Ofdm And Ofdm-Cdma System, Jie Cheng
Theses
High Peak to Average Power Ratio is a main problem in Orthogonal Frequency Division Multiplexing(OFDM) system and Orthogonal Frequency Division Multiplexing -Code Division Multiple Access (OFDM-CDMA) system. Considering a compensated High Power Amplifier(HPA), in order to keep linearity for amplification, Input Back-Off(IBO) of the HP-A, has to be increased for handling a high PAPR. Higher 1130 will make HPA less efficient. Additionally, a signal with high PAPR will suffer clipping when PAPR is larger than 1130 of the HPA. Clipping can cause the distortion of the signal and deteriorate the performance of the system. Reduction of PAPR is a main …

Phase Tunability In A Conductor Backed Coplanar Waveguide Patch Antenna, Idan Mandelbaum
Phase Tunability In A Conductor Backed Coplanar Waveguide Patch Antenna, Idan Mandelbaum
Theses
Traditionally beam steering in phase array antenna systems is achieved using tunable phase shifters or switched feed networks. Here, a tunable patch antenna element is suggested as a novel alternative to a combination of a radiating element and a phase shifter. A conductor backed coplanar waveguide patch antenna is chosen due to its suitability to mounted external tuning elements, using varactor diodes. Limited types of lumped tuning circuits, using varactor diodes, have been tested, though a lumped as well as distributed tuning is feasible in the chosen antenna configuration. Approximate analytical models for coplanar waveguide patch antennas with finite ground …

An Investigation Into The Effect Of The Compression Algorithm In The Presence Of Shifting And Cropping On Image Quality, Ornsiri Thonggoom
An Investigation Into The Effect Of The Compression Algorithm In The Presence Of Shifting And Cropping On Image Quality, Ornsiri Thonggoom
Theses
Image compression is a form of data compression frequently used in digital imaging applications to improve the efficiency of transmission and storage. In order to have a manageable file size, the data compression is lossy, i.e. image information is lost. Lossy compression algorithms such as Baseline JPEG use the insensitivity of the human eye to high frequency information as a basis for the compression. Discrete cosine transforms (DCT) are performed on the data followed by variable quantization. And the image blocking has no exact regulations for the spatial variation. Using this technique, information is lost and the decompressed image is …

Bipolar Disorder And Locus Of Control: Implications For Treatment Compliance, Linda J. Ryan-Cox
Bipolar Disorder And Locus Of Control: Implications For Treatment Compliance, Linda J. Ryan-Cox
Theses
Theoretically, a paradigm shift in the 1960s made community-based care and out-patient treatment an acceptable alternative to institutionalization of the chronically mentally ill. Utilizing the Levenson Multidimensional Locus of Control Scale for Psychiatric Patients, the author conducted a causal-comparative study to determine if a link exists between having bipolar disorder, a chronic mental illness, and an external locus of control, a link which might explain the inability of this population to maintain their optimal level of mental health utilizing the out-patient treatment model. Though the study failed to demonstrate any significant differences in external measures of loci of control between …
