A dual case study : students' perceptions, self-efficacy, and understanding of the nature of science in varied introductory biology laboratories.
(2016-11-27)Since World War II, science education has been at the forefront of curricular reforms. Although the philosophical approach to science education has changed numerous times, the importance of the laboratory has not waned. ... -
A fast seeding technique for k-means algorithm.
(2014-11-06)The k-means algorithm is one of the most popular clustering techniques because of its speed and simplicity. This algorithm is very simple and easy to understand and implement. The first step of this algorithm is choosing ... -
A fruitless crown : the logic and limits of foreign policy in revolutionist dictatorships.
(2015-03-25)This dissertation examines the process of foreign policymaking in dictatorial regimes, using historical examples to illustrate contemporary implications for American foreign policy. I introduce a sub-category of regimes ... -
A hydrologic assessment of water chemistry and aquifer properties in the Middle Trinity Aquifer in Bell and McLennan Counties in Texas.
(2018-05-02)The Middle Trinity Aquifer is part of a freshwater aquifer spanning southern Oklahoma and Central Texas. Increasing demand from population growth has promoted a need to better understand productivity and associated aquifer ... -
A hypnosis intervention reduces anxiety among postmenopausal women with hot flashes : results from a randomized controlled trial.
(2018-07-13)Anxiety is common, yet under-treated, among women in menopause and postmenopause. This study examined the effect of a hypnotic intervention designed to reduce hot flashes, on anxiety levels of postmenopausal women. Anxiety ... -
A low-cost embedded network analyzer for the measurement of material properties.
(2015-04-08)Many industrial processes involve the production of complex composite mixtures of multiple constituents that must be combined according to carefully controlled ratios. Inaccuracies in the control of the production processes ... -
A method for replicating ice accretion roughness using multi-scale analog distributions.
(2018-03-23)A new approach of creating an analog surface for a surface with natural roughness is presented based on the hypothesis that the dominant skin friction and heat transfer augmentation mechanisms are 1) the vortex shedding ... -
A methodology for chemoselective carbonyl ylide formation, total synthesis of (±)-aspergilline A, cyclopiamide A and speradine E and progress toward the total synthesis of (±)-isopalhinine A.
(2018-10-12)In 2001, the total synthesis of (±)-epoxysorbicillinol was completed by Wood and coworkers. This work featured as the key step a Rh(II) catalyzed carbonyl ylide formation and subsequent dipolar cycloaddition of a diazomalonate ... -
A multigrid Krylov method for eigenvalue problems.
(2015-07-31)We are interested in computing eigenvalues and eigenvectors of matrices derived from differential equations. They are often large sparse matrices, including both symmetric and non symmetric cases. Restarted Arnoldi methods ... -
A multimethod examination of the relevance of executive control to disgust and mental contamination among female sexual assault survivors.
(2018-06-06)Sexual assault among women is a significant and ongoing public health problem in the United States, and studies indicate a particularly high prevalence of sexual assault among college-aged women. A large body of research ... -
A neural inspired grid cell aid for robot intertial navigation.
(2018-05-08)Accurate position information is needed for a robot's guidance and control systems. Therefore, the navigation system is foundational for a robot's interactions with the world. This thesis explores a biologically inspired ... -
A photogrammetric method for measuring transient frost surface roughness.
(2018-11-26)Cold-soaked fuel frost (CSFF) is a form of aircraft wing contamination that results in aerodynamic degradation. Unless a certification exemption for a specific aircraft model is provided by the FAA, an operator of an ... -
A pilot study : evaluation of the effectiveness of a cooking class in increasing cancer patients' self-efficacy, sense of control and knowledge.
(2016-03-20)Nutrition and cancer patients’ food choices impact treatment outcomes and survival rates. The goal of nutrition education is dietary behavior change, yet it is unclear which educational format is the most effective. The ... -
A pilot study on the effects of brief-ACT on college student drinking, correlates of drinking, and cognitive fusion.

A polysemic exploration of stereotypes and racial humor in Tosh.0.
(2015-07-22)This case study uses content and rhetorical analyses to address the neutralizing effects of performance strategies used in the racially charged humor of “Tosh.0.” Selected clips were analyzed and discussed through the lens ... -
A power contrast of tests for homogeneity of covariance matrices in a high-dimensional setting.
(2018-10-31)Multivariate statistical analyses, such as linear discriminant analysis, MANOVA, and profile analysis, have a covariance-matrix homogeneity assumption. Until recently, homogeneity testing of covariance matrices was limited ... -
A pragmalinguistic analysis of missed opportunities for building rapport in interpreted medical interviews with Spanish-speaking patients.
(2016-03-14)Interpreted medical discourse presents significant challenges for communication because portions of the original message are often reduced, omitted, or revised (Aranguri, Davidson, & Ramirez, 2006), particularly by lay ... -
