Multipolar-Guided-Mode-Resonant Photon Sources

The design process to reach this condition involved a lot of trial and error. Through this process, I developed an intuition for how each resonance was affected by alterations I made to the design. Meeting the above condition creates a correlated photon source that can produce quantum entangled photon pairs, which are key for many quantum communication device

Guided-Mode-Resonance as a Source of Entangled Photons

Four wave mixing is a phenomenon in nonlinear optics where interactions between two input frequencies produce new two new frequencies. This interaction arises from the third-order nonlinearity of the medium. I am using a variation of four wave mixing called degenerate four wave mixing. This is where the two input frequencies coincide, leading to the doubled input frequency producing resonances at two different frequencies

Central Florida Educational Leaders\u27 Professional Opinions Of The Race To The Top Grant Components Concerning Teacher Evaluation And Compensation Prior To Implementation

This mixed-methods study was conducted to explore the professional opinions of educational leaders regarding selected components in the Race to the Top (RTTT) grant concerning teacher evaluation and compensation and the potential impact on student achievement. A target university was selected that had students who were professionals in the field of education in either instructional or administrative jobs and were pursuing their doctorates in both Education and Educational Leadership. A researcher created survey and follow-up interview were utilized to gather both quantitative and qualitative data for analysis. Quantitative findings revealed that statistically significant differences in the opinions of educational leaders about the potential impact of the RTTT grant teacher evaluation and compensation components on student achievement existed between two types of professional classification (instructional or administrative). No statistically significant relationship was found between self-reported knowledge of the RTTT and opinions of the fairness of the RTTT teacher evaluation and compensation components. Also, no statistically significant difference was found in the professional opinions about the potential impact of the RTTT grant teacher evaluation and compensation components on student achievement when self-reported school poverty percentage was considered. From qualitative findings, themes emerged surrounding the uncertainty and lack of understanding about the RTTT grant’s implementation. Though this study provided baseline data on the opinions of educational leaders on the RTTT teacher evaluation and compensation components, there is still much to be learned about the RTTT grant

Semiconductor High-Energy Radiation Scintillation Detector

We propose a new scintillation-type detector in which high-energy radiation produces electron-hole pairs in a direct-gap semiconductor material that subsequently recombine producing infrared light to be registered by a photo-detector. The key issue is how to make the semiconductor essentially transparent to its own infrared light, so that photons generated deep inside the semiconductor could reach its surface without tangible attenuation. We discuss two ways to accomplish this, one based on doping the semiconductor with shallow impurities of one polarity type, preferably donors, the other by heterostructure bandgap engineering. The proposed semiconductor scintillator combines the best properties of currently existing radiation detectors and can be used for both simple radiation monitoring, like a Geiger counter, and for high-resolution spectrography of the high-energy radiation. The most important advantage of the proposed detector is its fast response time, about 1 ns, essentially limited only by the recombination time of minority carriers. Notably, the fast response comes without any degradation in brightness. When the scintillator is implemented in a qualified semiconductor material (such as InP or GaAs), the photo-detector and associated circuits can be epitaxially integrated on the scintillator slab and the structure can be stacked-up to achieve virtually any desired absorption capability

Initial External Validation of REGRESS in Public Health Graduate Students

Linear regression is typically taught as a second and potentially last required (bio)statistics course for Public Health and Clinical and Translational Science students. There has been much research on the attitudes of students toward basic biostatistics, but there has not been much assessing students’ understanding of critical regression topics. The REGRESS (REsearch on Global Regression Expectations in StatisticS) quiz developed at Mayo Clinic utilizes 27 questions to assess understanding for simple and multiple linear regression. We performed an initial external validation of this tool with 117 University of Michigan public health students. We compare the results of pre‐ and postcourse quiz scores from the Michigan cohort to scores of Mayo medical students and professional statisticians. University of Michigan students performed higher than Mayo students on the precourse quiz due to previous related coursework, but did not perform as high postcourse indicating the need for course modification. In the Michigan cohort, REGRESS scores improved by a mean (standard deviation) of 4.6 (3.4), p < 0.0001. Our results support the use of the REGRESS quiz as a learning tool for students and an evaluation tool to identify topics for curricular improvement for teachers, while we highlight future directions of research.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/110068/1/cts12190.pd

The effect of providing a USB syllabus on resident reading of landmark articles

Background: The acquisition of new knowledge is a primary goal of residency training. Retrieving and retaining influential primary and secondary medical literature can be challenging for house officers. We set out to investigate the effect of a Universal Serial Bus (USB) drive loaded with landmark scientific articles on housestaff education in a pilot study. Methods: We created a USB syllabus that contains 187 primary scientific research articles. The electronic syllabus had links to the full-text articles and was organized using an html webpage with a table of contents according to medical subspecialties. We performed a prospective cohort study of 53 house officers in the internal medicine residency program who received the USB syllabus. We evaluated the impact of the USB syllabus on resident education with surveys at the beginning and conclusion of the nine-month study period. Results: All 50 respondents (100%) reported to have used the USB syllabus. The self-reported number of original articles read each month was higher at the end of the nine-month study period compared to baseline. Housestaff rated original articles as being a more valuable educational resource after the intervention. Conclusions: An electronic syllabus with landmark scientific articles placed on a USB drive was widely utilized by housestaff, increased the self-reported reading of original scientific articles and seemed to have positively influenced residents&#x2019; attitude toward original medical literature

The Continuing Search to Find a More Effective and Less Intimidating Way to Teach Research Methods in Higher Education

Existing literature examining the teaching of research methods highlights difficulties students face when developing research competencies. Studies of student-centered teaching approaches have found increased student performance and improved confidence in undertaking research projects. To develop a student-centered approach, it could be beneficial to teach students through active participation, with the development of their research agendas as the basis for progression. To develop this goal, the research methods module for graduate students at a UK business school was restructured into a two-week block utilizing a student-centered approach. The performance of the students was then compared to the performance of students who undertook the same course material presented in a traditional semester-long module and the results were then statistically analyzed. The results of this study provide new and interesting evidence of increased student achievement and understanding through the new format and provide new avenues for future research
