Social Media Sentiment Analysis With A Deep Neural Network: An Enhanced Approach Using User Behavioral Information, Ahmed Sulaiman M. Alharbi

Dissertations

Sentiment analysis on social media such as Twitter has become a very important and challenging task. Due to the characteristics of such data (including tweet length, spelling errors, abbreviations, and special characters), the sentiment analysis task in such an environment requires a non-traditional approach. Moreover, social media sentiment analysis constitutes a fundamental problem with many interesting applications, such as for Business Intelligence, Medical Monitoring, and National Security. Most current social media sentiment classification methods judge the sentiment polarity primarily according to textual content and neglect other information on these platforms. In this research, we propose deep learning based frameworks that …

Moreover, the study proved that to an extent western instruments, such as the MLQ (Bass & Avolio, 2004), TCM (Allen & Meyer, 2004), and MSQ (Weiss, Dawis, England, & Lofquist, 1967), do work in …

Comparing The Results Of And Evaluating Preferences For Functional Analyses And Concurrent Operant Analyses, Marrisa B. Allen

Dissertations

It is recommended that a functional analysis (FA) be conducted before treating serious problem behaviors. However, it is not always feasible or desirable to do so. For example, the problem behavior may be too dangerous, or the setting may not allow procedures that evoke problem behavior. An alternative solution may be to identify reinforcers for adaptive behavior in order to develop a treatment plan to reduce problem behavior by increasing socially appropriate/adaptive behavior. Berg et al. (2007) evaluated whether the same social events identified as reinforcers for adaptive behavior by a concurrent operant (i.e., choice) analysis (COA) would be identical …

Embedded Silver Nanoparticles For Metal Enhanced Photoluminescence, Shahid Iqbal

Dissertations

Imaging of biologically significant molecules using plasmons of Metal Nanoparticles (MNPs) is gaining attention in the research community. Localized Surface Plasmon Resonance (LSPR) is the coherent oscillation of conduction electrons of MNPs. The biologically significant molecule is labeled with the fluorophore molecule to get the image. This approach is widely used in clinical practices, however, low intensity light emission from the labeled molecule makes it difficult to image the biologically significant material. One way to improve the weak intensities of fluorophore is to enhance the brightness using a process called Metal Enhanced Photoluminescence (MEP). This phenomenon occurs in the close …

Since their introduction to the United States in 2008, synthetic cannabinoids became the most widely used recreational drug behind marijuana, then regressed to an estimated prevalence of less than 1%. Contrary to expectations for a drug declining in use, emergency department presentations and acute poisonings related to the use of synthetic cannabinoids are increasing. Alongside this phenomenon, a growing body of literature is beginning to uncover a relationship between psychosis and synthetic cannabinoid use. A current gap in the literature exists surrounding harm prevention methods and targeted intervention strategies for users of synthetic cannabinoids. To date, no known studies have …

Male Reproductive Strategies In Wild Northern Pig-Tailed Macaques (Macaca Leonina): Testing The Priority-Of-Access Model, Florian (Allen Trebouet

Dissertations

Among multi-male, multi-female primate groups, males engage in direct contest competition for access to mates. The priority-of-access model (PoA model) generally predicts that male reproductive success increases with male dominance rank, but the strength of this relationship is expected to decrease with increasing female reproductive synchrony, particularly in seasonally breeding primates. Genetic paternity studies support the model’s predictions, having found a positive relationship between male dominance rank and reproductive success. However, in addition to dominance status and female reproductive synchrony, a number of proximate factors also impact males’ ability to sire offspring, which have not been considered in studies of …

Consequently, institutions of higher education continue to focus efforts on student retention strategies and one such strategy utilizes academic recovery courses to support probationary freshmen. Previous research studies of these courses largely focus on academic outcomes without examining the “why” or “how” behind such outcomes. Some studies also discuss constructs including attribution perspective, shame, and academic identity. However, the relationship between these constructs has not been researched, particularly with regard to any change that may occur for probationary freshmen engaged with an …

The Impact Of Goal Orientation And Learning Organization On Mobbing Of Academic Advisors In The U.S., Bette A. Ludwig

Dissertations

Mobbing emerged in research decades ago as a way to understand aggressive behavior in the animal kingdom (Lorenz, 1966). This same concept has been adapted for higher education to explain acts of incivility and negative behaviors employees experience within their institutions (Duffy & Sperry, 2007, 2012; Harper, 2016; Yelgecen & Kokalan, 2009). The theory of mobbing encompasses both the organization and the aggressor.

This quantitative study, operationalized using measurable behaviors from the Work Domain Goal Orientation Questionnaire (Vandewalle, 1997), the Dimension of Learning Organization Questionnaire (Watkins and Marsick, 1993), and the Negative Acts Questionnaire (Einarsen, 1997), researches mastery orientation, performance …

An Experimental Comparison Of Visual And Statistical Analyses, Stevie A. Collini

Dissertations

Visual analysis is the favored method for analyzing single-subject research data in more traditional behavior analysis programs of study; however, some critics of the practice argue that it should not be the only method used to analyze data given the previous research demonstrating significant inconsistencies in conclusions drawn based on the practice (Bulté & Onghena, 2012; Campbell & Herzinger, 2010; Kazdin, 2011). Supporters of statistical analysis have argued that although statistical analyses are not free from subjectivity and bias, the decision-making processes and criteria are more straightforward than those offered by the complexities involved in visual analysis (Kazdin, 2011).
