Can Wearable Devices Reduce Burnout By Making People Aware Of Stress?, Rohit Mundayaliyath Mundayadan

Open Access Theses

Wearable fitness technology is advancing in its capabilities. Every new sensor collects new health data, and it becomes important to study how effectively this data can be utilized to help people lead healthier lives. The American Psychological Association found that Americans live with stress levels higher than what is considered healthy. Poorly managed stress can lead to burnout, which leads to unproductive workers. Burnout is known to cost businesses considerable money. The goal of this research study was to determine if burnout could be reduced through the use of a consumer wearable device along with smartphone apps that alerted wearers ...


Dopamine D1 Receptor Activity In The Basolateral Amygdala Is Important For Mediating Fear, Reward And Safety Discrimination Learning, Ka Ho Ng Dec 2016

Dopamine D1 Receptor Activity In The Basolateral Amygdala Is Important For Mediating Fear, Reward And Safety Discrimination Learning, Ka Ho Ng

Open Access Theses

Post traumatic stress disorder (PTSD) patients frequently show impairment in safety learning (Jovanovic, Kazama, Bachevalier, & Davis, 2012). Since the amygdala is known to be critical for emotional processing(Wassum & Izquierdo, 2015) and dopamine signaling in the amygdala is important for mediating both fear and reward learning, current experiments examined the role of dopamine signaling in the BLA in mediating both safety learning and reward seeking. We manipulated dopamine D1 receptor activity with a D1 receptor agonist (SKF 38393) or D1 receptor antagonist (SCH23390) either systemically or infused directly into the BLA 20 minutes prior to training rats in a fear-safety-reward ...

The Swiss German Language And Identity: Stereotyping Between The Aargau And The Zurich Dialects, Jessica Rohr Dec 2016

The Swiss German Language And Identity: Stereotyping Between The Aargau And The Zurich Dialects, Jessica Rohr

Open Access Theses

Swiss German dialects contribute to the social identity of a speaker, especially on a local level (Christen, 1995). Many dialects of Switzerland are associated with a common stereotype which relates to the identity of the speakers (Rash, 2002). This research looks at these notions and investigates concepts of identity ascription and stereotyping that arise between and from the dialects of canton Aargau and canton Zürich, in Switzerland. The generation of a definition of identity for the project, drawing off existing identity theories in sociolinguistics, and stereotyping theories, allow for an investigation of how the Aargau and Zürich dialects fit into ...


Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers Dec 2016

Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers

Open Access Theses

Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting ...

Using Academic And Learning Analytics To Explore Student Success In An Online Graduate Program In Communication, Megan N. Bergman

Open Access Theses

Fueled by the increase in data associated with the use of learning management systems, scholars and practitioners alike have been trying to explain and predict student success; yet the use of data analytic methods (academic and learning analytics) in higher education has created challenges and shortcomings for those who wish to adopt learning and academic analytics practices for their institution or program. Very little is known about either online education, particularly in the field of communication, as well as in online graduate and professional degree programs in any field from a learning and academic analytics perspective. This work reviews the ...


Using Construal Level Theory To Promote Hpv Vaccine Uptake Among College Males, Julie Cannon Aug 2016

Using Construal Level Theory To Promote Hpv Vaccine Uptake Among College Males, Julie Cannon

Open Access Theses

College males’ uptake of human papilloma virus (HPV) vaccination is low. Prior research indicates perceived susceptibility to HPV among college males is also low. Construal level theory may offer a framework to alter perceived susceptibility and intention to vaccinate, but little research has examined this potential. Construal level theory provides foundational elements including that low construal level of perceptions is associated with more proximal psychological distance (hypothetical, social, temporal and spatial). Research indicates a disparity in college males’ susceptibility estimates which suggests high hypothetical distance. A reduction in hypothetical distance should be indicated by a measured increase in perceived susceptibility ...


Authentic Enterprise, Communal Employee Relationship, And Employee-Generated Managerial Assets, Yeunjae Lee Aug 2016

Authentic Enterprise, Communal Employee Relationship, And Employee-Generated Managerial Assets, Yeunjae Lee

Open Access Theses

This study aims to explore managerial intangible assets of organizations generated by their internal publics, employees. Considering employees’ perception and communicative behaviors as an organization’s managerial assets, this study examines an organization’s authentic behaviors and organization-employee relationships. To be more specific, this study firstly investigates how an organization’s authentic behavior—truthfulness, transparency, and consistency—affects communal relationship between employees and an organization. Using megaphoning, scouting, and microboundary spanning as theoretical frameworks for employees’ communicative behaviors (ECB), this study also examines the association among perceived authenticity of organizational behavior, organization-employee relationships, and employees’ communicative actions. Furthermore, this study ...

Impact Of Peer Relationship And Exposure To Violence On Posttraumatic Stress For Children At Risk For Maltreatment, Aura Ankita Mishra Aug 2016

Impact Of Peer Relationship And Exposure To Violence On Posttraumatic Stress For Children At Risk For Maltreatment, Aura Ankita Mishra

Open Access Theses

Post-traumatic Stress (PTS) symptomology includes ruminating thoughts and feelings around trauma, inability to feel and express emotions, and avoidance of things related to the traumatic event (American Psychiatric Association, 2000). Children and youth exposed to child maltreatment (abuse and neglect) are at higher risk of experiencing PTS. Extra-familial support, including peer support can reduce post-traumatic stress among youth (Pina et al., 2008). In the present study, Witnessing, Victimization, and Both Witnessing and Victimization due to Exposure to In-Home Violence and Peer Relationship Quality are evaluated as to their relative impact on PTS for children at risk for child maltreatment. Peer ...


Superheroes And Social Action: Reproduction, Recurrence, And Recognition In The Superhero Genre, Max M. Renner Aug 2016

Superheroes And Social Action: Reproduction, Recurrence, And Recognition In The Superhero Genre, Max M. Renner

Open Access Theses

Rhetorical genre analysis examines genre as social action and is primarily concerned with the experiences of individual users (Miller, 1984). The genres that rhetorical genre scholarship takes up are typically functional genres or genres in which individuals have direct means of utilizing and modifying a genre. This focus on functional genres makes sense in terms of the tradition’s interest in user experience and reciprocity. This project seeks to examine the potential implications rhetorical genre analysis has for vernacular genres which, for the most part, have remained the domain of literary scholarship due to their focus on structural, formal elements ...


Relationship Quality, Engagement, Hope, Self-Worth, And Health-Risk Behaviors In A Physical Activity-Based Positive Youth Development Program, Shaina Cole Riciputi Aug 2016

Relationship Quality, Engagement, Hope, Self-Worth, And Health-Risk Behaviors In A Physical Activity-Based Positive Youth Development Program, Shaina Cole Riciputi

Open Access Theses

Physical activity-based positive youth development (PYD) programs have the potential to promote positive psychosocial and personal growth (Fraser-Thomas, Côté, & Deacon, 2005) and reduce health risk behaviors in youth (Tebes et al., 2007). Engagement, a motivationally-oriented construct representing the subjective quality of youths’ connection to a program (Skinner, Kindermann, Connell, & Wellborn, 2009), may help promote the positive outcomes associated with PYD participation. Based on competence motivation theory (Harter, 2012), program staff may affect engagement by providing instructional feedback related to program activities, and by fostering the interpersonal climate within the program. This study examined whether youths’ perceptions of their relationship with ...


Impact Of Communication Appeals On Recycling Behaviors Among Undergraduate Students, Ning Zhu Aug 2016

Impact Of Communication Appeals On Recycling Behaviors Among Undergraduate Students, Ning Zhu

Open Access Theses

The present thesis aims to understand factors influencing student recycling behaviors, and to investigate effective communication approaches to increase such behaviors. An online survey was conducted to examine the relationships between student recycling frequency in different contexts, students’ attitudes toward the environment, barriers to their recycling, students’ perceptions of communication messages, and communication media they think to be effective. Descriptive statistics, ANOVAs, t-test, simple linear regressions, categorical multinomial logistic regression, and a chi-square test were conducted, and the data was collected from a large land-grant university in the Midwestern United States. A total of 537 questionnaires were answered.

Set And Element-Level Compatibility Of Spatial And Location-Word Stimuli Paired To Eye-Movement, Vocal, And Keypress Response Modalities, Courtney Janai Griffin-Oliver Aug 2016

Set And Element-Level Compatibility Of Spatial And Location-Word Stimuli Paired To Eye-Movement, Vocal, And Keypress Response Modalities, Courtney Janai Griffin-Oliver

Open Access Theses

Set-level and element-level compatibility are two ways to differentiate between different components of stimulus-response compatibility. Element-level compatibility (the difference between incongruent and congruent mappings) has been shown in prior studies to be an increasing function of set-level compatibility (differences between pairings of stimulus and response ensembles). When manual and vocal response sets are paired with spatial (physical location) stimuli and verbal (location-word stimuli), the difference between the incongruent and congruent mappings is larger for the spatial-manual and verbal-vocal conditions than for the alternative pairings of lower set-level compatibility.

The common use of eye tracking technology in psychological experiments necessitates investigating ...


Economic Viability Of Flexible Biogas Pumps In Bangladesh, Saima A. Matin Aug 2016

Economic Viability Of Flexible Biogas Pumps In Bangladesh, Saima A. Matin

Open Access Theses

This study examines the economic viability of flexible irrigation pumps that can run on biogas as well as diesel fuel in Bangladesh. Such examination faces two main hurdles. First, the ease with which farmers running flexible pumps can switch from one energy source to another is unknown and perhaps highly heterogeneous. Second, diesel prices in Bangladesh are volatile and limited information precludes direct estimation of their probability distribution. We address the first issue by evaluating the economics of flexible pumps for varying degrees of inter-fuel substitutability. To deal with the second issue, we model the probability distribution of Bangladeshi diesel ...


The Labor Market Consequences Of Endogenous Low-Skill Migration With A Market-Based Immigration Policy, German A. Marquez Alcala Aug 2016

The Labor Market Consequences Of Endogenous Low-Skill Migration With A Market-Based Immigration Policy, German A. Marquez Alcala

Open Access Theses

The undocumented migration of Mexican nationals to the U.S. is largely influenced by labor demand in low-skill sectors. The legal migration channels available to Mexican nationals with little education are based on family petitions and subject to visa quotas which are dwarfed by the demand for entry to the United States; visa approval can take upwards of 20 years for a Mexican national with little education and few resources. Thus, undocumented immigration is a more responsive unskilled labor distribution mechanism than the existing quota-based immigration policy. However, the restrictive legal migration channels and increased costs of undocumented migration are ...

Firm Demography And Location Decisions In The United States After 1990, Francisco Albert Scott Aug 2016

Firm Demography And Location Decisions In The United States After 1990, Francisco Albert Scott

Open Access Theses

This thesis deals with firm formation and location choice of firms in the manufacturing (and commercial service) sector in the United States after 1990. The topics of firm formation and location choice are part of a wider field that is usually referred to as "firm demography.'' We start off with a description of the size structure of firms by looking at the evolution of the average size of manufacturing firms in counties in the USA between 1990 and 2011. We hypothesize that the size of manufacturing firms depends on the firm sizes in proximate regions as well as on the ...


Experimental Evaluation Of An Ipad-Based Augmentative And Alternative Communication Program For Early Elementary Children With Severe, Non-Verbal Autism, Ariana Azzato Aug 2016

Experimental Evaluation Of An Ipad-Based Augmentative And Alternative Communication Program For Early Elementary Children With Severe, Non-Verbal Autism, Ariana Azzato

Open Access Theses

The purpose of this study was to evaluate the efficacy of a treatment package including a modified protocol of the Picture Exchange Communication System (PECS) implemented via an autism-specific iPad application. A multiple probe design (Horner & Baer, 1978) was replicated across four individuals with severe, non-verbal autism to investigate effects on requesting skills, natural speech production, and social-communicative behaviors. Results suggest beneficial effects, if implemented with high fidelity. The largest effects were on the participants’ requesting skills. All four participants were able to consistently request for desired items by activating the tablet device, and this skill was maintained after a ...


The Meaningfulness Of Internships: A Sensemaking Approach, Kaley Campbell Aug 2016

The Meaningfulness Of Internships: A Sensemaking Approach, Kaley Campbell

Open Access Theses

Internships are an important part of undergraduate education, with more than 61% of students completing an internship, yet there is not much academic literature surrounding this topic (NACE, 2015). Using Weick’s (1995) sensemaking theory, report data was analyzed thematically looking at how interns made sense of their experiences and what they found to be meaningful. This study found four distinct themes that interns used to navigate unique tensions and power dynamics within their organizational setting: “Just an intern,” “It’s up to me,” “For my future,” and “I was allowed.” Future research could explore framing internships more as a ...


Beyond The Gender Gap: Understanding Women's Participation In Wikipedia, Danielle J. Corple Aug 2016

Beyond The Gender Gap: Understanding Women's Participation In Wikipedia, Danielle J. Corple

Open Access Theses

In 2010, UNU-MERIT researchers surveyed editors of Wikipedia, “the online encyclopedia that anyone can edit” (Glott, Ghosh, & Schmidt, 2010). When the report revealed that almost 90% of the editors were male, however, it suggested that perhaps not everyone “can edit” Wikipedia—especially women. As the resulting media and academic explanations of the Wikipedia “gender gap” have largely attributed the gap to ‘female lack’—lack of initiative, confidence, or technical skills—very little research has explored the treatment of women within Wikipedia culture. Thus, this paper first draws upon feminist technology scholars to problematize current explanations of the gender gap that ...


Seeking Certainty: Are People Who Are Experiencing Relational Doubt More Sensitive To Relationship Cues?, Christine Ann Daly Aug 2016

Seeking Certainty: Are People Who Are Experiencing Relational Doubt More Sensitive To Relationship Cues?, Christine Ann Daly

Open Access Theses

Experiencing uncertainty in one’s relationship is likely an aversive experience and a motivating factor in restoring confidence about where things stand. Thus, uncertain partners may place more weight on positive and negative interactions with their partner as they seek greater confidence in their evaluation of their relationship. The present research examined how partners responded to two different types of relationship information: a past relationship experience (Study 1, N= 154) and false feedback about its quality (Study 2, N = 154). Results suggest that while partners appear to place significance on positive information, regardless of their uncertainty, whether or not uncertain ...


Make The Connection: Personal And Institutional Identity In The U.S. Department Of Veterans Affairs Ptsd Campaign, Staci B. Smith May 2016

Make The Connection: Personal And Institutional Identity In The U.S. Department Of Veterans Affairs Ptsd Campaign, Staci B. Smith

Open Access Theses

The common procedure in a health campaign is to use fear and guilt appeals to influence health behaviors among target populations (Mattson & Lam, 2016). The use of identity, identification, and reframing in a health campaign has been relatively under-explored. This study examines invitations to identification and reframing in a specific health campaign, the U.S. Department of Veterans Affairs (VA) “Make the Connection” campaign. With the issues of mental health and post-traumatic stress disorder (PTSD) reaching high levels of attention in media and society, the VA’s Make the Connection campaign encourages military veterans and their families to seek help ...

Open Access Theses

Long-distance romantic relationships have become quite common nowadays. With CMC tools advancing day-by-day, their usage among LDRs is proliferating rapidly. Attachment-related anxiety and avoidance can block the ability to enjoy happy relationships. During such situations, remembering happy past moments can be comforting. In this study a mobile chat application that enables LDR couples to reminisce about happy moments was developed. This study primarily focuses on evaluating the usability of this mobile application using survey-based methods. System Usability Scale was considered to discuss the outcome of the study. The overall results provide useful recommendations for further improvements in the design of ...


Rethinking Reference: Towards A Holistic Approach To Linguistic Reference, Libby C. Chernouski Apr 2016

Rethinking Reference: Towards A Holistic Approach To Linguistic Reference, Libby C. Chernouski

Open Access Theses

In this thesis, a review of linguistic reference identifies four entities (speaker, hearer, term, and object) and their interrelations as falling under the umbrella of reference. This review brings to light certain underdeveloped areas of research into linguistic reference, and the second chapter addresses these gaps by distinguishing between the experiences of speaker and hearer as regards linguistic reference, differentiating between the cognitive processes required by each interlocutor, asking how the speaker establishes reference pre-utterance, and drawing on various pragmatic, philosophic, and semantic approaches and theories to see how they could begin to approach for this important issue. A holistic ...


Quit Playing With Your Watch: Perceptions Of Smartwatch Use, Christopher M. Gaeta Apr 2016

Quit Playing With Your Watch: Perceptions Of Smartwatch Use, Christopher M. Gaeta

Open Access Theses

This study identified perceptions and social norms that may affect smartwatch adoption. Interviews were conducted to identify perceptions of smartwatch use and norms that might affect those perceptions.

Smartwatch use was found to activate norms associated with wristwatch use – specifically, smartwatch users’ peers took offense to the users looking at their wristwatches. This study also found that norms prevent the use of smartwatches’ voice controls in public and various perceptions of smartwatch use and ownership.
