Development Of A Methodology For Predicting Consumer Acceptance And Preference Toward Beverages, Shilpa Shailesh Samant

Graduate Theses and Dissertations

Consumer behavior toward food/beverages is influenced by multisensory attribute perceptions as well as emotional experiences. Traditional methods of sensory testing lack the ability to capture emotional responses and as a result, measuring food/beverage-evoked emotions remains a research challenge. There were three objectives of this dissertation study. Firstly, this study aimed to develop prediction models of acceptance of and preference for basic taste solutions using sensory attribute intensities and emotional responses. Secondly, this study aimed to extend the findings of the first objective to develop prediction models of commercially-available vegetable juice products in terms of (a) acceptance and preference under blind-tasting …

The Role Of Dialect Words In Children’S Social Decisions, Madison Rose Myers-Burg

Graduate Theses and Dissertations

Recent research suggests that young children are capable of distinguishing between phonetically dissimilar spoken accents, yet have difficulty distinguishing between phonetically similar accents (Wagner, Clopper, & Pate, 2013). The present study aimed to determine whether the presence of dialect-specific vocabulary enhances young children’s ability to categorize speakers. Participants completed four training trials in which they were familiarized with photos of two children: one of whom used American English labels for test objects and one of whom used British English labels. After training trials, participants completed eight test trials in which they were asked to infer which target child would use …

Effects Of Task Clarification And An Adaptive Computer Software On Implementation Of Mand Training Using An Ipad® As A Speech Generated Device, Ashley Mckenzie Parnell

Graduate Theses and Dissertations

Mand training is an evidence-based instructional method and a primary focus in behavioral language training for children with autism. A rapidly growing research base supports manding training using hand-held computing technologies (e.g., iPad®, iPod®) as speech generating devices (SGD) for establishing a manding repertoire in children with autism. To ensure optimal learning efficacy and efficiency, procedures must be implemented with high levels of accuracy, which requires that staff be well-trained. However, research evaluating methods for training staff to implement mand training procedures with the iPad® and application Proloquo2Go™ as an SGD has not yet been conducted. Therefore, this study examined …

Values Vs. Self-Interest As Determinants Of Attitudes: Through A Construal Level Theory Lens, (Sometimes) Self-Interest Wins, Austin D. Eubanks

Graduate Theses and Dissertations

The present study (n = 335) attempted to conceptually replicate Hunt, Kim, Borgida, and Chaiken (2010) with a high-powered design to investigate whether values and self-interest differentially impact attitudes depending on psychological distance. Participants were assigned to complete a task that made self- or other-focused values more accessible, then indicated their attitudes about a student fee increase at a university to fund scholarships the participants would not be eligible to receive (thus going against their own financial self-interest for the well being of someone else). The memo describing the fee increase was manipulated such that the increase would be occurring …

Investigating Affective Pathways For The Influence Of Justification On Self-Control, Morgan Hill

Graduate Theses and Dissertations

People struggle with temptation in their everyday lives. Research often attributes failures in self-regulation to overwhelming and uncontrollable impulses. However, research also supports the idea that cognitive factors (e.g., justification) can license tempting behavior and allow individuals to behave in ways that run counter to their long-term goals. In addition, it is likely that affect plays a role in justification-based self-control failure. The current set of three studies investigated the role of affect in justification-based self-control failure. Study 1 tested the prediction that recall of past successes would result in increased positive affect. Study 2 assessed whether justification results in …

Emotion Differentiation Moderates The Effects Of Rumination On Depression: A Longitudinal Study, Yunjing Liu

Arts & Sciences Graduate Student Theses and Dissertations

Elevated trait rumination is associated with and predicts the onset of major depressive disorder (MDD), but not all people with elevated trait rumination develop MDD. We hypothesize that certain emotional processes weaken the rumination-depression link, protecting people against increases in depression. In the current prospective longitudinal study, we examined one such process, emotion differentiation—the ability to identify and label specific emotions. Because higher negative emotion differentiation (NED) has been associated with greater psychological well-being and people typically ruminate in the context of negative affect, we predicted that NED, but not positive emotion differentiation (PED), would moderate the rumination-depression association, such …

Bayesian Estimation Of Mixture Irt Models Using Nuts, Rahab Al Hakmani

Dissertations

The No-U-Turn Sampler (NUTS) is a relatively new Markov chain Monte Carlo (MCMC) algorithm that avoids the random walk behavior that common MCMC algorithms such as Gibbs sampling or Metropolis Hastings usually exhibit. Given the fact that NUTS can efficiently explore the entire space of the target distribution, the sampler converges to high-dimensional target distributions more quickly than other MCMC algorithms and is hence less computational expensive. The focus of this study is on applying NUTS to one of the complex IRT models, specifically the two-parameter mixture IRT (Mix2PL) model, and further to examine its performance in estimating model parameters …

The Evaluation Of Attitudes Towards Individuals With Mental Illness Among Counselors In Training, Randall Boen

Dissertations

Negative attitudes and stigma associated with mental illness have a profound impact on individuals who experience them. Researchers have defined stigma as the attribution of a deviant characteristic to members of a particular group. Persons with severe and persistent mental illness (SPMI) face many difficulties that impact their full participation in social life. Although attitudinal reactions to individuals with SPMI have improved considerably over the last few decades, there are still areas for improvement. Limited research has been conducted to evaluate attitudes and stigma associated with individuals with SPMI among human service professionals-in-training (HSPs). For this study HSPs were defined …

‘Commensality’ As A Theatre For Witnessing Change For Criminalised Individuals Working At A Resettlement Scheme., Julie M. Parsons

School of Law, Humanities and Social Sciences

This article draws on analysis of interview data from an exploratory case study at an independent ‘offender’ resettlement scheme in England, investigating the benefits or otherwise of commensality for criminalised individuals and the wider community who share a communal lunchtime meal. For prisoners released on temporary licence and others referred through probation, caught in the liminal space between criminal and civilian life, commensality enables social interaction with non-criminalised individuals in a social environment outside of the prison estate. It becomes an arena for the display of non-criminalised identities in preparation for release into the community after punishment. It is a …

Investor Sentiment And Advertising Expenditure, G. Mujtaba Mian, Piyush Sharma, Ferdinand A. Gul

All Works

© 2018 Elsevier B.V. A strategic issue facing marketing managers is ‘how much and when’ to spend on advertising. We argue that investor sentiment in the stock market may influence advertising expenditure by affecting firms’ ability to raise new funds. We show that during periods of low (high) investor sentiment, firms decrease (increase) their advertising expenditure, even though the effectiveness of advertising is greater (lower) during such periods. We also find that these results are stronger for financially constrained firms that rely more on external financing. Our findings suggest that marketing managers can improve the efficiency of their advertising expenditure …

Money And Happiness For College Students, Robin Leonard

Honors Theses

This study was designed to expand the field of positive psychology and to investigate the relationship between money and happiness in college students. “Money” was further defined as financial satisfaction, and “happiness” was further defined as overall satisfaction with life for the purposes of the study. Existing psychological research demonstrates that many factors influence overall satisfaction with life, including face consciousness, perceived material wealth, goal setting, motivation orientation, cultural value, and the wealth of one’s home nation. However, less research has been conducted on the effects of finances on happiness. The research that does exist focuses on a specific range …

Implementation Of Music In A Simulated Unmanned Aircraft System (Uas) Monitoring Task To Alleviate The Vigilance Decrement, Maria Chaparro

Theses and Dissertations

The vigilance decrement is a thoroughly researched phenomenon in psychological literature and has been identified in many monotonous tasks. Although the phenomenon has been recorded for approximately 80 years, no universal repair, or theory to account for its onset, has been identified. Jobs requiring monotonous task performance have been increasing as time has elapsed, in part due to the rise in automation. Furthermore, much of the vigilance literature does not address modern, more complex tasks, such as the Unmanned Aerial Systems (UAS) monitoring task. A potential method that has been proposed to combat the vigilance decrement is the inclusion of …

Exploring Person-Organization Fit And Gender Bias In The Hiring Process Of Engineering Firms: Is Selection Impacted?, Vicky W. Knerly

Theses and Dissertations

Are We Safe Yet? Re-Evaluation Of The Performance Diagnostic Checklist-Safety (Pdc-Safety), Nelmar Jacinto Cruz

Theses and Dissertations

This study evaluated the utility of the Performance Diagnostic Checklist- Safety (PDC-Safety) (Martinez-Onstott, Wilder, & Sigurdsson, 2016) by comparing the effectiveness of a PDC-Safety indicated intervention with a PDC-Safety nonindicated intervention. The interventions targeted participants’ hand washing behavior at a clinic serving children with intellectual disabilities. Failure to wash hands at appropriate times could pose health risks to both behavior technicians and clients, so efforts should be made to increase the likelihood of hand washing. The results of the PDC-Safety suggested that the antecedents and information domain was most problematic. First, a non-indicated intervention, which included access to additional materials …
