An Evaluation Of The Effect Of Degradation On Irisplex Snps, Maria Gruber
An Evaluation Of The Effect Of Degradation On Irisplex Snps, Maria Gruber
Master's Theses
The information from short tandem repeats (STRs), the current standard forensic DNA typing technology, does not always result in identification. In these cases, there are other informative markers in DNA that can be used to help generate investigative leads, one of which is single nucleotide polymorphisms (SNPs). One of the uses of SNPs is for phenotype determination. Among the phenotypic characteristics that can be predicted is eye color. A commonly used tool for eye color prediction is the free, online statistical prediction model IrisPlex, which includes 6 SNPs known to control eye color.
While SNPs can be useful, they, like …
Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston
Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston
Master's Theses
In investigations, locating missing persons and clandestine remains are imperative. One way that first responder and police agencies can search for the remains is by using cadaver dogs as biological detectors. Cadaver dogs are typically used due to their olfactory sensitivity and ability to detect low concentrations of volatile organic compounds produced by biological remains. Cadaver dogs are typically chosen for their stamina, agility, and olfactory sensitivity. However, what is not taken into account often is the size of the animal and the expense of maintaining and training the animal. Cadaver dogs are typically large breeds that cannot fit in …
Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis
Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis
Master's Theses
This study aspires to find a new screening approach to trace DNA recovery techniques to yield a higher quantity of trace DNA from larger items of evidence. It takes the path of visualizing trace DNA on items of evidence with potential DNA so analysts can swab a more localized area rather than attempting to recover trace DNA through the general swabbing technique currently used for trace DNA recovery. The first and second parts consisted of observing trace DNA interaction with Diamond Dye on porous and non-porous surfaces.
The third part involved applying the Diamond Dye solution by spraying it onto …
Evaluation Of Raman Microspectroscopy And Hyperspectral Imaging As A Screening Tool To Determine Optimal Sampling Sites For Dna Recovery From Human Skeletal Remains, Kathleen M. Smith
Evaluation Of Raman Microspectroscopy And Hyperspectral Imaging As A Screening Tool To Determine Optimal Sampling Sites For Dna Recovery From Human Skeletal Remains, Kathleen M. Smith
Master's Theses
Numerous challenges exist with forensic genetic testing of human skeletal remains due to diagenesis patterns in bone microstructure, DNA degradation, and the presence of PCR inhibitors. Diagenesis is the microscopic breakdown of the bone matrix, which consists primarily of mineralized calcium hydroxyapatite and collagen. The process of diagenesis occurs in a heterogeneous, non-uniform manner along the diaphysis of a long bone, and determining the region with the most intact bone microstructure is not possible with the naked eye. Therefore, taking cuttings from the diaphysis for DNA testing is somewhat of a “blind” process, and decades of research and casework have …
Post Pandemic Cyberbiosecurity Threats From Terrorist Groups, Haley D. Dodge
Post Pandemic Cyberbiosecurity Threats From Terrorist Groups, Haley D. Dodge
Master's Theses
The research in this thesis explored the research question: Are United States (US) health systems accessible to cyber-bio terrorist attacks post-pandemic, within the context of the emerging discipline of cyberbiosecurity? Key findings of the analysis demonstrated how US health systems are more accessible to cyber-bio terrorist attacks specifically from cyber hacking groups based on the increasing sophistication of their cyber capabilities and the lack of cyber protection for biological systems. The concept of cyberbiosecurity was first introduced in 2018 by researchers exploring the converging threat landscape of the cyber and biology domains. As biology is growing more dependent upon vulnerable …

Correlation Between Tooth Root Translucency, Crystallinity, And Dna Preservation In Teeth For Unidentified Human Remains (Uhr) Investigations, Paul Yount
Master's Theses
Endogenous genetic material protected by the rigid, mineralized hard tissues of bones and teeth is often targeted for forensic DNA testing in missing persons and unidentified human remains (UHR) investigations. Although standard approaches have narrowed sample selection to a few optimal skeletal elements (i.e., weight-bearing long bones, teeth), subsampling and decisions beyond this can be challenging due to the non-uniform, heterogeneous pattern of postmortem diagenesis. One particular component of skeletal microstructure — the inorganic mineral matrix [hydroxyapatite (HAp), Ca10(PO4)6(OH)2] — is purported to play a major role in DNA preservation. The potential correlation between molecular changes to skeletal microstructure and …

Emergency Management Plan To Increase Resilience In Transportation Sector Vehicles To An Emp Attack, Julian A. Lorusso
Master's Theses
A vulnerability exists in the U.S. to an attack from a nuclear weapon of mass destruction (WMD) optimized to generate an electromagnetic pulse (EMP) with potential for widespread damage to electrical components in the critical infrastructure including non-military (non-MIL) transportation sector vehicles. The purpose of this study was to develop a plan on how hazard risks from an EMP attack can be better understood for modern-day, “electronics-heavy”, transportation sector vehicles leading to affordable mitigation countermeasures that could be implemented as part of an emergency management plan. The FY2020 National Defense Authorization Act (NDAA) and preceding executive order signed by the …
Multiple Contacts Of Drug Contaminated Fingermarks And Their Analysis With Raman Microspectroscopy, Victoria Deprimo
Multiple Contacts Of Drug Contaminated Fingermarks And Their Analysis With Raman Microspectroscopy, Victoria Deprimo
Master's Theses
This thesis research aimed to determine if substrate, enhancement technique, and multiple contacts affect the detection and identification of drugs in fingermarks using Raman Spectroscopy. It has the potential to be of great importance in forensic science as fingermarks are one of the most important traces left behind at crime scenes and illicit drugs are a significant criminal justice problem. Thus, being able to associate illicit drugs with a specific fingermark has great potential for forensic science, as it can put the drugs in the hands of a specific individual.
The ridges of fingerprints trap trace amounts of material that …
Determining The Interference Of Lactate And Lactate Dehydrogenase In An Ethanol Enzyme Assay, Julia Liebl
Determining The Interference Of Lactate And Lactate Dehydrogenase In An Ethanol Enzyme Assay, Julia Liebl
Master's Theses
Enzymatic ethanol assays are widely used to determine blood alcohol content for individuals admitted to a hospital. In some instances, this hospital data is later used as evidence in a court of law, most commonly in DUI cases. As the enzymatic assay targets, but does not exclusively measure ethanol, it is theoretically possible that interference could occur and produce a falsely elevated result, leading to wrongful convictions or other consequences. This project examined the potential of clinically relevant levels of one potential interferant, lactate and the hepatic enzyme lactate dehydrogenase (LDH) to cause significant and falsely elevated results. Threshold levels …
Investigating The Masking Effects Of Blood On Organic Gunshot Residue Using Gc/Ms, Raman, And Atr-Ftir, Tyler Willits
Investigating The Masking Effects Of Blood On Organic Gunshot Residue Using Gc/Ms, Raman, And Atr-Ftir, Tyler Willits
Master's Theses
Gunshot residue (GSR) can be an indicator for determining the distance of a firearm discharge and linking potential suspects and witnesses to a shooting event. However, the evidentiary value of inorganic gunshot residue (IGSR), commonly used to detect GSR, has been called into question due to the potential for false negatives and false positives. Organic gunshot residue (OGSR) acts as supporting evidence; this increases the overall confidence of the examiner, as well as the value of gunshot residue evidence as a whole.
Current research has focused on three main areas for OGSR. The first is what compounds we should identify …
Dna Methylation Methods For Donor Age Prediction Using Touch Dna, Emily Neverett
Dna Methylation Methods For Donor Age Prediction Using Touch Dna, Emily Neverett
Master's Theses
The International Labor Organization (ILO) estimated over 30 million individuals fall victim to human trafficking each year, of which, 50% are children below the age of 16. In 2012, the ILO reported there to be 168 million child laborers worldwide, with many trafficked into hazardous conditions to manufacture consumer products that are sold in developed countries. This is a modern form of slavery with poor working conditions, no access to education, and low wages. The hidden nature of this crime, however, makes it extremely difficult to identify and locate victims of forced child labor, and thus making it challenging to …

Forensic Characterization And Discrimination Of Manila Envelopes, María Isabel Sánchez Melo
Forensic Characterization And Discrimination Of Manila Envelopes, María Isabel Sánchez Melo
Master's Theses
Envelopes can be found at crime scenes when ransom, threat letters or potentially harmful substances are sent to victims. Therefore, they are important probative items of evidence analyzed by forensic document examiners. Manila envelopes are commonly used in the United States to transport or send documents as they are made of thick and durable paper. Although there are many studies on the forensic analysis of office paper and paper-based banknotes, and only a few on white envelopes, there does not exist previously published research on the physical or chemical characterization of manila envelopes. The goal of this research was to …
Detection Of Larval Aggregations Using A Drone Mounted Thermal Imaging Camera, Megan Descalzi
Detection Of Larval Aggregations Using A Drone Mounted Thermal Imaging Camera, Megan Descalzi
Master's Theses
When a body’s temperature reaches ambient temperature after death, remote detection of the body can become difficult. At this point, useful search tactics include the use of cadaver dogs, search parties and aerial imaging devices, all of which can be costly and time-consuming for every day law enforcement use. This study investigated the potential of a novel search technique in which a small, unmanned aerial system (drone) mounted with a forward-looking infrared radar (FLIR) was utilized to detect decomposing animal carcasses via the heat generated by associated Diptera larval aggregations. Hot water baths were utilized as analogs for larval aggregations …

Utilizing data from Queens and the Bronx, NYC, this study examines RSO clustering in the two boroughs and explores the proximity of community resources to RSO addresses that may assist reintegration. Using data from the New York Megan’s Law and census data for Queens and Bronx Counties, maps were created to study the residential patterns of RSOs. The results show clustering of RSOs in areas with variables pertaining to high social disorganization and a lack of …
Small Rna Sequencing And Rt-Qpcr Validation Of Forensically Relevant Body Fluids, Karly Johannsen
Small Rna Sequencing And Rt-Qpcr Validation Of Forensically Relevant Body Fluids, Karly Johannsen
Master's Theses
Body fluid identification is an important aspect of forensic investigations because it assists with the reconstruction of crime scenes and can refute and/or support witness statements. Currently, there is no universal method for body fluid identification. Each body fluid has several tests for its identification, both presumptive and confirmatory. A universal method for body fluid identification that is sensitive, specific, efficient, and minimally destructive is necessary.
In recent years miRNAs have been heralded as novel biomarkers for the identification of body fluids. Several research groups across the US and internationally have been formed to determine which miRNAs are suitable for …
Construction Of A Reference Allelic Ladder For An Odocoileus Str Multiplex, Jolene Strand
Construction Of A Reference Allelic Ladder For An Odocoileus Str Multiplex, Jolene Strand
Master's Theses
Odocoileus is a genus of Cervidae (deer) consisting of white-tailed deer (Odocoileus virginianus, Zimmerman, 1780), mule deer (Odocoileus hemionus, Rafinesque, 1817) and blacktailed deer (Odocoileus hemionus hemionus, Rafinesque, 1817). Hunting Odocoileus is only legal with proper permits according to laws that dictate when, where, how, and what can be hunted. Anything outside the legal limits is considered to be poaching. A useful tool for investigating poaching cases is Short Tandem Repeat (STR) DNA analysis. This is commonly used in human forensic casework to link DNA evidence found at crime scenes to either victims or suspects. In poaching cases, it can …

Primers for genetic regions rbcL and matK of M. citrifolia were designed. The potential of novel matK primer showed discrimination potential …
The Impact Of Environmental Degradation On The Analysis Of Manufactured Fibers, Alexis R. Weber
The Impact Of Environmental Degradation On The Analysis Of Manufactured Fibers, Alexis R. Weber
Master's Theses
The analysis of fiber evidence involves the ability to link a questioned fiber back to its known source. But before the collection and analysis of questioned fibers, they could be potentially exposed to various environmental conditions for an extended period of time. There has been little research on how manufactured fibers are affected by various environments and if this interaction affects the ability to link a questioned fiber back to its known source. Changes to the manufactured fibers are essential to be aware of, in order to avoid the possibility of erroneous exclusions when performing fiber comparisons. A six-month time …
Conflict Management Training In Video-Based Teams, Alexis Ward
Conflict Management Training In Video-Based Teams, Alexis Ward
Master's Theses
In the wake of an emerging economy that demands organizational agility, globalization and an increasing number of independent contractors, corporations have exponentially incorporated virtual teams in their organizations. However, despite their financial and geographical convenience, research has indicated that virtual teams have consistently experienced more conflict and lowered performance and satisfaction levels than that of their traditional counterparts. The present study sought to examine whether conflict management training could help video based virtual teams demonstrate more positive conflict handling techniques and less negative techniques, which would result in higher group process and group outcome satisfaction. This study did not find …
