Development And Validation Of The Client Ratings Of Counselor Competence: Applying The Rasch Measurement Model, Hang Jo

Electronic Theses and Dissertations

An important part of becoming a counselor is developing strong counselor competence, particularly for counselors-in-training. Thus, the main goal in counselor education is to develop students' competence to be capable to practice as a professional counselor. Assessing the competence of counselors-in-training remains the primary focus in counselor education and supervision (Bernard & Goodyear, 2014; McAuliffe & Eriksen, 2011; Swank & Lambie, 2012). There have been various attempts to measure the true construct of counselor competence (e.g., Hughes, 2014; Swank, Lambie, & Witta, 2012; Urbani, Smith et al., 2002). Those attempts tried to involve diverse voices around counselor competence in more …

A Correlational Study Of Emerging Modalities Of Developmental Education And Learning Styles In A Florida State College., John Britt Jan 2016

A Correlational Study Of Emerging Modalities Of Developmental Education And Learning Styles In A Florida State College., John Britt

Electronic Theses and Dissertations

Developmental education course modalities in Florida were drastically changed in 2013 with the passage of Senate Bill 1720. These courses can no longer be offered in a traditional 16-week format as other postsecondary courses are offered. Developmental education courses must now be offered in a compressed, contextualized, or corequisite instruction modality; or direct enrollment into a gateway course (1720-Education, 2013). This changes the student's experience in the courses. This research was framed by Kolb's experiential learning theory, which states that people learn through their experiences (Kolb, 1984). Chi-Square correlational tests were conducted to examine the relationship between students' learning types …

Classification Of Silicone-Based Personal And Condom Lubricants Using Dart-Tofms, Lauren Harvey

Electronic Theses and Dissertations

Sexual lubricants are used to enable sexual encounters. There are different types of sexual lubricants such as water-based, oil-based, and silicone-based. They come pre-applied to condoms and separately in bottles as personal lubricants. Although sexual lubricants are intended for consensual use, they are also unfortunately used during the commission of sexual assaults. The analysis of sexual lubricants facilitates sexual assault investigations. With the increased usage of condoms in sexual assault cases, the potential of collected DNA evidence in each case is reduced. In the absence of biological evidence, the presence of sexual lubricants after a sexual assault can provide an …

Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun Jan 2016

Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun

Electronic Theses and Dissertations

We introduced a method presented in Information Field Theory (IFT) [Abramovich et al., 2007] to improve interpolation in Smoothed Particle Hydrodynamics (SPH) in cases of less smooth flow. The method makes use of wavelet theory combined with B-splines for interpolation. The idea is to identify any jumps a function may have and then reconstruct the smoother segments between the jumps. The results of our work demonstrated superior capability when compared to a particular challenging SPH application, to better conserve jumps and more accurately interpolate the smoother segments of the function.

Monolithically Integrated Inp-Based Unidirectional Circulators Utilizing Non-Hermiticity And Nonlinearity, Parinaz Aleahmad

Electronic Theses and Dissertations

The need to integrate critical optical components on a single chip has been an ongoing quest in both optoelectronics and optical communication systems. Among the possible devices, elements supporting non-reciprocal transmission are of great interest for applications where signal routing and isolation is required. In this respect, breaking reciprocity is typically accomplished via Faraday rotation through appropriate magneto-optical arrangements. Unfortunately, standard light emitting optoelectronic materials like for example III-V semiconductors, lack magneto-optical properties and hence cannot be directly used in this capacity. To address these issues, a number of different tactics have been attempted in the last few years. These …

Optical Parity Time Metasurface Structures, Ahmed El Halawany Jan 2016

Optical Parity Time Metasurface Structures, Ahmed El Halawany

Electronic Theses and Dissertations

In the last few years, optics has witnessed the emergence of two fields namely metasurfaces and parity-time (PT) symmetry. Optical metasurfaces are engineered structures that provide unique responses to electromagnetic waves, absent in natural materials. Optical metasurfaces are known for their reduced dimensionality i.e. subwavelength and consequently lower losses are anticipated. The other paradigm is the PT symmetric materials, also known as photonic synthetic matter. PT symmetry has emerged from quantum mechanics when a new class of non-Hermitian Hamiltonian quantum systems was highlighted to have real eigenvalues, hence eradicating Hermiticity of the Hamiltonian as an essential condition to the existence …
