Reducing Workplace Conflict: A Reasonable Expectation?, Stephen Mark Kominek

Department of Conflict Resolution Studies Theses and Dissertations

Workplace conflict is a part of everyday work life for many employees, from educationalinstitutions to businesses, and can occur for multiple different reasons. Research has shown that employees spend a significant amount of their life in the workplace and that addressing unresolved conflict is one of the costliest aspects of running an organization. The literature suggests that providing employees with the opportunity to experience greater job satisfaction may reduce the occurrence of workplace conflict. This quantitative study explored the experience of workers employed in various organizations and institutions. The theoretical frameworks applied in the study were Systems Theory and Maslow’s …

Beyond Human Error: Seafarers’ Perceptions About Their Interpersonal Conflicts In A Multicultural Workplace A Typology Of Seafarers’ Conflicts Contributing To Maritime Accidents, Eugenio Moreno

Department of Conflict Resolution Studies Theses and Dissertations

Marine incidences and casualties result in occurrences like loss of lives, personal injuries, collisions, allisions, hull and machinery damages, and environmental damages. Therefore, this study’s purpose was to examine seafarers’ perceptions of their interpersonal conflicts on board the vessels in a multicultural workplace and to examine whether they perceive that those interpersonal conflicts may contribute to the human errors that lead to marine casualties and incidences. A two-method approach (quantitative and qualitative) was used. The theoretical framework guiding this study consisted of four theories, which were culture and interpersonal relationship conflict, social identity theory, organizational interpersonal and task conflicts theory …

Caregiver Acceptability Of Differential Reinforcement Procedures For Honest Reports Of Transgressions, Stephanie C. Bowar

University of the Pacific Theses and Dissertations

When measuring social validity, many researchers rely exclusively on subjective measures, such as questionnaires or surveys; however, these measures may fail to capture the variables that control later intervention adoption by stakeholders, and objective measures may capture these variables more accurately. Moreover, few researchers have investigated the adoptability of differential reinforcement (DR) interventions to increase children’s honesty about transgressions. We taught caregivers to implement the DR procedures reported in Lehardy et al. (2023) and measured the acceptability and adoptability of procedures using three measures: (1) a social validity questionnaire and rating scale immediately following training, (2) a concurrent-chains preference assessment …

A Mixed-Method Analysis Of The News Media Framing Of Gender Non-Conforming Victims Of Homicide In The U.S. From 2012 To 2022, Susana Avalos, Hayley Jackey, Iyan Wickel

Sociology & Criminal Justice Faculty Publications

Recent analyses of transgender homicide victims find that the news media often uses improper terminology, delegitimizes, and victim blames them. These analyses, while insightful, are limited as they have largely analyzed cases involving trans women and trans feminine individuals. The present study employs a mixed-method approach to analyze news media articles (N = 88) published in U.S. online news media outlets about 17 gender non-conforming victims killed between 2012 and 2022. We found that most articles did not delegitimize or victim blame. However, we find (1) victim blaming occurred when reporting on cases of officer-involved shootings, (2) certain victims …

Public Attitudes Towards Non-Criminal Preventive Detention As A Function Of The Covid-19 Pandemic, Matt Zaitchik, Kyle Gamache, Judith Platania

Arts & Sciences Faculty Publications

Non-criminal preventive detention is justified by both the state’s parens patriae and police power roles. Individuals with mental illness and individuals with a highly communicable, potentially lethal disease can be involuntarily detained. Modern applications of quarantine have led to higher court decisions that address the balance between liberty and public health and safety. The inherent tensions that underlie quarantine law – individual liberty versus public safety – are apparent in our contemporary, COVID-19 America. Consequently, much of the current discussion appears to have political overtones. In order to empirically address this issue, in the current study we examine attitudes towards …

Quantifying The Potential Health Impacts Of Unvented Combustion In Homes – A Meta- Analysis, P. Jacob Bueno De Mesquita, Nuria Casquero-Modrego, Iain Walker, Brennan D. Less, Brett C. Singer

Arts & Sciences Faculty Publications

While a growing body of scientific literature describes the population health impacts of fossil fuel production and burning via climate and air pollution pathways, less is known about the health impacts of indoor combustion. This paper summarizes the results of studies from the last two decades that investigated the association between exposure to sources of unvented combustion pollutants in homes and a range of health outcomes. We found gas combustion to be associated with 6-28% (95% confidence intervals) increased odds of asthma symptoms, 4-51% increased odds of systemic symptoms, 7-81% increased odds of asthma medication use, and 3-12% increased risk …

Potential Causes Of Racial Disparities In Wrongful Convictions Based On Mistaken Identifications: Own-Race Bias And Differences In Evidence-Based Suspicion., Jacqueline Katzman, Margaret Bull Kovera

Publications and Research

Objective: We explored whether racial disparities in evidence-based suspicion (i.e., evidence of guilt prior to placement in a lineup) provide a better explanation of racial disparities in exonerations based on eyewitness misidentification than the own-race bias in eyewitness identifications. Hypotheses: We predicted that the own-race bias in identification accuracy would be insufficiently large to fully explain the racial disparities in wrongful convictions in cases with mistaken identification. We also predicted that possible racial disparities in the prior probability of suspect guilt before subjecting suspects to the risk of misidentification might better explain racial disparities in wrongful convictions. Method …

Differences In Religious Framing Of Muslims And Islam In American Media Coverage Before And After The Trump Campaign, Emily Greene-Colozzi, Amy Adamczyk, Senahan Kiyal Keles

Publications and Research

Over the last 20 years Muslims have received a disproportionate amount of news media attention. In 2017 they were again thrust into the spotlight when the Trump administration issued a travel ban blocking entry from seven predominately-Muslim countries. With our hand coding of over 900 newspaper articles and mixed modeling techniques, we examine the newspaper rhetoric surrounding Muslims before and during the Trump administration and across US states. We find that after President Trump’s election, fewer newspapers mentioned religion or referenced Muslim claimsmakers. We also reveal that higher state-level religious salience was associated with more newspapers referencing religious claimsmakers in …

Evaluation Of Cytokeratin-Specific Antibody And Autofluorescent Signals As Predictors Of Time Since Deposition For Saliva Samples, Dillon Ryder

Master of Science in Forensic Science Directed Research Projects

In a forensic investigation, STR profiles generated from biological evidence can frequently be informative to identify an individual or provide an investigative lead. However, STR typing does not provide information to answer activity-level questions which can be highly important to a criminal case, such as the Time Since Deposition (TSD) of biological evidence. Determining the relative time in which a biological sample was left at a crime scene would provide additional information regarding the timeline of a crime and a person of interest’s relationship to the scene. One proposed method of estimating TSD is to use flow cytometry to analyze …

Dysgonomonas, unclassified Proteobacteria, Escherichia, Ignatzschia, Providencia, …

Bones As An Alternative Matrix For The Detection Of New Synthetic Opioids In Cold Cases: Introducing New Animal Models For Bone:Blood Correlation Studies, Kala N. Babb

Master of Science in Forensic Science Directed Research Projects

Introduction: The growing opioid epidemic in North America presents a call to action to develop new techniques for the identification and quantitation of novel synthetic opioids in uncommon matrices. In instances of extreme decomposition and/or significant scavenging, bone may be the only matrix available. In order to develop an extraction method for synthetic opioids in bone, bone samples were obtained from animal models. The animal model of choice is the rabbit due to their exhibition of spontaneous cortical bone remodeling, a process that is exhibited in humans but not in rats and mice.

Methods: An extraction method was developed to …

Assessment Of The Acidified Hydrogen Peroxide Method On Uncontrolled Fired Cartridge Case Samples, Kylie S. Richardson

Master of Science in Forensic Science Directed Research Projects

The use of fingerprints to identify individuals in forensic cases has been useful for many years due to the persistence and individuality of the prints. In addition, the presence of firearms in forensic casework is steadily increasing over the years. This study aims to expand upon prior research in the development and recovery of latent prints on fired, brass ammunition using an acidified hydrogen peroxide method. Although latent prints are left on the cartridge casing of ammunition during the handling and loading of ammunition into the firearm, it is hypothesized that the pressure within the barrel of the firearm during …

Investigation Into The Relationship Between Dna Content And Dna Yield Prediction And Presence Of A Multiple Contributor Cell Population In Trace Dna, Sarah Holton Roisch

Master of Science in Forensic Science Directed Research Projects

Due to advancements in DNA analysis technology and an increased ability to detect trace quantities of low template DNA, ‘touch’ or trace DNA has become a prevalent form of evidence for forensic investigations. Trace DNA is biological material left on a surface from skin cells after being touched or handled. The success rate of casework could be improved with new methods to non-destructively screen trace DNA to predict DNA yield and whether multiple cell populations are present in the evidence prior to STR analysis. Current methods of trace DNA analysis require quantifying the sample with qPCR followed by STR analysis, …

Optimization Of Microfluidic Device Methodology For Optical Trapping Epithelial Cells In A Mixture, Brittney N. Hackworth

Master of Science in Forensic Science Directed Research Projects

Evidence containing biological mixtures can make DNA interpretation more difficult due to ambiguous allele calls and artifacts that may be present within electropherograms. Separating out these cell mixtures can be advantageous to the analysts’ analysis methods for identifying STR profiles with higher accuracy. A potential cell separation method that could be implemented in the beginning of the forensic DNA workflow is optical trapping.

This research utilized a 5W ytterbium linearly polarized laser split into two optical traps, paired with a microfluidic device to isolate spermatozoa and vaginal epithelial cells from a 1:1 mixture of vaginal fluid and 1:20 diluted seminal …

Comparison Of Cell Counts To Dna Yield In Mock Biological Evidence Samples, Jacob Sewell

Master of Science in Forensic Science Directed Research Projects

The implementation of rapid DNA analysis systems is of interest to forensic DNA casework, as this technology exhibits a sample-to-profile time of approximately two hours with limited handling of samples. This decreases the likelihood of contamination, and can potentially reduce DNA backlogs; however, current rapid DNA analysis systems do not execute one crucial step of the forensic DNA analysis workflow: human DNA quantitation. This step is necessary for DNA profiles to be compliant with the FBI’s Quality Assurance Standard 9.4, allowing DNA profiles to be uploaded and searched within the CODIS database. Coupling traditional qPCR methods with rapid DNA analysis …

Development And Validation Of Microrna Markers For Forensic Body Fluid Identification Using Rt-Qpcr, Jane Goble

Master of Science in Forensic Science Directed Research Projects

Body fluid identification is one of the first and most fundamental steps in the forensic DNA workflow. It allows analysts to determine where a sample might exist on an item of evidence, as well as the type of sample that they are dealing with. However, current serological methods have been documented to produce false or inaccurate results in some cases, and may consume large amounts of sample during processing. Molecular methods, such as the use of microRNA and microbial profiles have been introduced as a means to increase specificity of testing, and have even been combined into a singular assay …

Evaluation Of Direct-To-Amplification Cell Lysis Techniques For Forensically Relevant Non-Sperm Cells, Rhea Arya

Master of Science in Forensic Science Directed Research Projects

While efforts have been made to reduce the pervasive backlog of sexual assault evidence collection kits, the actual laboratory process remains very time-consuming due to the requirement of a differential lysis step before DNA purification, as well as intricate mixture analysis towards the end of the DNA workflow. Previous work in the Dawson Green laboratory at VCU has developed alternative solutions for differential extractions with sexual assault samples using both an in-tube and microdevice assay. Prior work led to the identification of an alternative sperm lysis method – alkaline lysis using 1M NaOH. However, the current lysis method used for …

Evaluation Of The Age Of Evidence In Mock Biological Touch Evidence Samples, Emma P. Hirst

Master of Science in Forensic Science Directed Research Projects

As more sensitive DNA profiling techniques have been developed, questions about how and when the DNA was deposited have become a driving issue in forensic casework. Image flow cytometry (IFC) offers a way to estimate the time since deposition (TSD) of trace DNA samples based on individual cells' morphological and autofluorescence properties. Previous work has shown that a TSD can be determined from a single contributor in touch samples. To determine if TSD could be correctly estimated for mixtures containing a fresh deposit (less than a week old) and an older deposit, this project characterized a series of samples that …

Analysis Of Forensic Relevant Cell Mixtures Using Cellular Autofluorescence And Fluorescence Activated Cell Sorting (Facs), Shayla Smith

Master of Science in Forensic Science Directed Research Projects

Biological mixtures containing DNA from more than one contributor can make DNA profile interpretation challenging, especially for ‘touch’ or trace biological evidence. One approach to improve this is by differentiating cell populations from separate individuals prior to DNA profiling by utilizing intrinsic features of cells such as size, shape, and biochemical profiles. The goal of this study was to develop a new method for detecting and separating contributor populations in biological mixture samples using flow cytometry, a rapid and non-destructive approach with an unexplored potential for forensic casework. To accomplish this, two different mixture systems were investigated (1) mixtures containing …

Determination Of The Trace Elemental Signature Of Drywall Dust And Its Implication As Forensic Evidence, Emilee Holmes

Master of Science in Forensic Science Directed Research Projects

Drywall is found in most homes built in the United States of America because it is cost effective, light weight, and easy to install. Its brittle nature makes it less resistant to impact which can cause dust to form if a force is exerted on it. Airborne dust can settle on anything or anyone around it and can be considered trace evidence for its ability to connect suspects, victims, and scenes; however, this type of dust is not emphasized as trace evidence and is not always collected due to a lack of understanding of their forensic signatures.The seven producers of …

Utilizing Gc-Ms To Determine The Effect Of Solvent Extraction Parameters On Forensic Smokeless Powder Analysis, Leighann R. Weber

Master of Science in Forensic Science Directed Research Projects

Since its invention in 1884, smokeless powder has been of scientific interest. During World War II, research initially focused on developing methods to evaluate powders' stability. However, today, the focus has shifted to developing instrumental techniques sufficient for forensic classification and comparison work. Smokeless powder is typically encountered in forensic science casework involving firearms and explosives. In forensic investigations, determining the exact formulation of smokeless powders is challenging due to their complex chemistry and the proprietary nature of production. LC-MS and GC-MS techniques have been used to analyze intact and post-blast smokeless powders. Despite the vast amount of research that …

Evaluation Of Tooth Sample Preparation For Traditional Forensic Dna Vs Rapidhit Id Processing, Morgan E. Eaton

Master of Science in Forensic Science Directed Research Projects

Disaster Victim Identification (DVI) refers to the process of forensic identification of unknown individuals following a mass disaster or fatality incident.¹ In events of mass disaster, human dental structures are often the only viable DNA source remaining, as soft tissues are more easily degraded, contaminated, or otherwise compromised. Due to the protective nature of dental enamel and dentin surrounding the inner pulpal tissue, a labor-intensive sample preparation performed by extensively trained personnel is necessary to expose the nuclear material preceding the traditional forensic DNA workflow.^2,3 In high volume cases, such as those often submitted for DVI, the current …

Morphological And Autofluorescence Signatures For The Identification Of Vaginal Cells In Mixture Samples Containing Saliva And/Or Epidermal Cells, Hannah L. Burden

Master of Science in Forensic Science Directed Research Projects

In forensic casework the identification of body fluids at a crime scene can frequently play an important role in reconstructing the events that occurred. There are several bodily fluid identification methods to characterize unknown stains recovered as evidence. However, there has not been a reliable method for detecting the presence vaginal cells and/or differentiate it from other forensically relevant tissue types that may be recovered from a crime scene. The detection of vaginal fluid is important for forensic casework due to the abundance of sexual assault kits that are not only backlogged but continue to be submitted to the lab …

Establishing Roots Before Branching Out: Parameter Recovery In Item Response Tree Models, Tyler Ryan

Browse all Theses and Dissertations

Item Response Trees are a type of item response model that incorporates information about conditional responding to items using a rooted tree graph structure. Researchers have used item response trees for common measurement tasks and for testing novel hypotheses. Previous simulation studies investigating item response trees either lack generalizability to the broad domain of their use or lack thorough investigation and reporting of the results. I conducted a simulation study to explore how sample size, test length, item characteristics, and tree structure affect both item and person parameter recovery for 1PL and 2PL models. The results suggested that, as with …

Autonomy :A Modern Perspective, Riley Schwanz

Browse all Theses and Dissertations

Organizational leaders want to retain employees who are healthy and motivated. Physical and mental health issues are on the rise in America for younger and older generations. Researchers have found that higher levels of autonomy relate to improved mental health, physical health, job satisfaction, performance, and the list goes on. However, a gap in the literature is a lack of understanding of the complex relationships between autonomy and outcomes, both functional and dysfunctional. I found that intrinsic motivation and autonomy support can compensate for lower levels of autonomy in one’s work. These new findings provide researchers and organizational leaders with …
