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

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

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

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 …

Predictors Of Intensive Supervision Placement Among Committed Youths Within A Maximum-Security Residential Facility, Tiffany Harris

Master's Theses

Some youths committed to juvenile justice residential facilities struggle to adjust and may exhibit institutional rule violations that necessitate an intensive supervision placement (ISP). ISPs require substantial institutional resources and may result in additional negative outcomes for these committed youths (e.g., additional charges, longer commitment). To date, only two studies have examined factors that place committed youths at greater risk of ISPs, and it was found that commitment length, number of arrests, age at admission, impulsive/reactive and psychopathic traits, and anger-irritability were predictive of ISPs (Taylor et al., 2007; Butler et al., 2007). The present study considered additional predictors that …

A Process Evaluation Of Aunt Mary’S Storybook: Seeking To Improve The Relationship Between Incarcerated Parents And Their Children Through Literacy, Scott Charles Mcwilliams

Master's Theses

In response to the rise of incarceration in jails and prisons, and the number of children adversely impacted by their parents’ incarceration, in 1993, a nonprofit organized called Companions Journeying Together (“CJT”), created the Aunt Mary’s Storybook (AMS) program to foster positive connections between incarcerated parents to their children. What began as a Christmastime program for mothers in the Cook County Jail has grown into a year-round program operating in prisons and jails throughout Illinois. AMS provides those incarcerated with an opportunity to record themselves reading a book to their children, and AMS then mails/transmits the recording along with a …

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 …

The Function Of The Hukou System In Post-Revolutionary China & Its Autonomous Regions, Joseph Kramer

Master's Theses

Over the course of more than two millennia the Hukou System has shifted in scope and purpose. In dynastic times it served as a mechanism of tax acquisition. In more recent years it has functioned as a method of census and land distribution. Today it holds a duplicitous function serving as both an economic and social control mechanism. The Hukou achieves this through controlling movement through a passport like system of internal registration. In simpler terms, think of the Hukou as an internal passport regulating movement while simultaneously holding all of your biometric data which is surveilled and controlled by …

The Socio-Demographic Factors Influencing Ntca Immigrants’ Accessibility To Mexico’S Health Care System, Ken Nishikata

Master's Theses

Mexico’s geographical location has made the country play a centric role in trans-national migration from the Northern Triangle of Central America (NTCA) comprising Guatemala, El Salvador and Honduras. As a result, immigration has increasingly become a political issue for Mexico over the past decades^[1]. Before the eruption of the Central American crisis in the 1980s, Mexico’s southern border with Guatemala was recognized for its openness. However, such a tolerating status-quo changed as the number of NTCA immigrants entering Mexico increased upon the exacerbation of the crisis that placed thousands of individuals in exile. Indeed, the turmoil during the …

What's Cookin'?: An Analysis Of Food As A Method Of Control In The Penal System, Zoe Livengood

Master's Theses

According to Garland (2001), the U.S. correctional system is a reflection of the culture of control that exists in American society. One way the correctional system exerts control is through food. This concept partnered with Foucault’s ideas about the evolution of punishment and the criminal justice system as an institution creates the theoretical foundation for food as a method of control in the correctional system.

Through quantitative and qualitative analysis, this study examined food as a method of control in three southern Mississippi jails in order to understand how food is a contested space for control between jail staff and …

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

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

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

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

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

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 …

Mapping Sex Offenders And Treatment Centers In Relation To Social Disorganization, Amber Amin

Master's Theses

Research shows that the clustering of Registered Sex Offenders (RSOs) is connected to social disorganization. Residential patterns disrupt the reintegration of the RSO population. 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

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

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 …

Assay Development For The Identification Of Species And Bioactive Compounds Of Morinda Citrifolia (Noni) In Dietary Supplements By Rt-Qpcr, Dna Sanger Sequencing And Spectroscopy (Uv-Vis/Ftir), Ricardo L. Fernandez Walker

Master's Theses

Regulation standards for dietary supplements lack greatly. Due to this, fraud during the manufacturing of these products might be committed. Previous investigations on herbal dietary supplements have shown that the main ingredient was not present in most of the herbal supplements tested and that these products also contained other substances not stated in the label The purpose of this study was to develop a fluorescent qPCR assay for the identification of Morinda citrifolia herbal species in dietary supplements. 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

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 …

A Qualitative Case Study On The Domestic Violence Act, 2007 (732) And The Convention On The Elimination Of All Forms Of Discrimination Against Women, Victoria Hernandez

Master's Theses

On July 17, 1980, Ghana became a signatory to CEDAW (Convention on the Elimination of All Forms of Discrimination against Women) under the United Nations in order to combat all forms of violence, discrimination and human rights violations that harm the security, freedom, privacy, and dignity of every woman. The Domestic Violence Act (732) stemmed from CEDAW in order to add on more layers of legal protection for victims of domestic violence and to penalize all acts according the bill’s definition and the different forms of domestic violence. Although there are stricter laws to punish any acts of violence inflicted …

A Content Analysis Of Section 1983 Litigation Against Reserve Police Officers, Michael Ryan Broadus

Master's Theses

Police studies have well developed a demonstrative framework for detailing risks which generate financially-detrimental civil litigation – particularly regarding 42 U.S.C. §1983. Conversely, though, police studies have given little attention to the often-used but differentially-trained reserve police officer. Primarily replicating the methodologies of Kappeler, Kappeler, and del Carmen (1993) and Ross (2000), this descriptive study sought to fill this void via a manifest content approach to purposively select a sample of Section 1983 cases decided by U.S. District Courts over a 16-year period (2001-2016) to determine: (1) if significant liability was generated by reserve officers, (2) the main basis for …

Black And Blue: Competing Social Constructions Of Police On Instagram And Twitter, Mary Frances Thornhill

Master's Theses

Mass media outlets newspapers and television were traditionally where individuals gathered their news information; however, with the growth of new media platforms like Twitter, Facebook, and Instagram, individuals are now co-producers of the content that is seen by the public. Previous research indicated that media-generated images of the police influence public perception and that new media outlets are becoming increasingly influential, particularly in regards to social and political conflicts. This means that research on the role of new media outlets in socially constructing reality is essential, though not much of this research has yet been completed. This current analysis fills …

Comparing The Risk Factors Of Recidivism For Offenders With And Without Mental Illness, Meghan J. Mahoney

Master's Theses

This study examined which risk factors were predictive of recidivism among inmates released from Illinois Department of Corrections (IDOC) who had no mental illness, a non-substance abusing mental illness (non-SUD MI), a substance use disorder (SUD), or a co-occurring mental illness and substance use disorder (COD). The predictors of being returned to prison or being rearrested for a violent, property, or drug crime were compared across these four groups. A secondary data analysis was conducted on data obtained by Olson, Stalans, and Escobar (2016) for a study examining the predictors of recidivism for inmates released from IDOC in 2007. Logistic …

State Failure In Venezuela, Marcus Littman

Master's Theses

The role of the state is to provide political goods such as security and an environment conducive to economic growth. The Venezuelan state is failing to provide both security and conditions capable of producing economic growth. The government has exacerbated both by enacting failed policies. I measure the economic crisis in Venezuela based on the rates of inflation, falling foreign currency reserves, the food and medical supply shortage, falling government spending, and negative GDP growth. I measure the security crisis based on the escalating rate of kidnapping, human trafficking, drug sales, smuggling, theft, gun distribution, and homicide. In this thesis, …

Master's Theses

Police academy training for newly hired officers varies across locations and regions in regard to both training process and training content. The needs and demands of modern-day societies have evolved, and it is very important for police training academies to keep up with the practice of the police profession. Higher education adds value to police training as it reinforces the development of critical thinking skills and the necessary values needed to face the needs and demands of society, particularly in terms of accountability, professionalism, and legitimacy. This research presents a case study of two police training academies located in a …

"I Can Haz Applicants": An Analysis Of Police Recruitment And Marketing Through Social Media, Kelly Lee Helldorfer

Master's Theses

In recent decades, the Internet has flourished with the advancement of social media: apps, blogs, social networking, multimedia sources, podcasts, and more. Consequently, the Millennial Generation has grown up immersed in both the Internet and social media networks differently than previous generations. Due to the rapid expansion of social media outlets and their effects on future employees, police departments must consider their agency “brand” and how effectively they market their departments to this generation for the purpose of recruitment both on the Internet and with social media platforms.

This research analysis employed a netnography to examine 500 police websites and …

Student Perceptions Of Mentally Ill Offenders, Kimberly Nicole Rayborn

Master's Theses

Since deinstitutionalization, the responsibility for mentally ill members of society has shifted to the criminal justice system in a process of trans-institutionalization or “criminalization of mental illness” (Slate & Johnson, 2008). Though various groups have been studied to ascertain their perception of mentally ill individuals and offenders, previous research focuses largely on students of psychology, social work, and medicine. Little research has been conducted regarding the perceptions of students of criminal justice toward mental illness, despite the increasing involvement of the criminal justice system in treating and handling mentally ill individuals in the past thirty years. This exploratory research serves …

High Resolution Melt Analysis Of Samples With Differential Dna Methylation To Identify Tissue Source Of Origin, Stephanie M. Ledgerwood

Master's Theses

In Forensic Science casework, identifying the source of a tissue can assist in crime scene reconstruction. Currently, presumptive testing methods to identify tissue type are utilized in crime scene laboratories, but there is a need for a more reliable confirmatory test for tissue type identification. High Resolution Melt (HRM) analysis is an innovative technology that has the potential to determine tissue types through variations in DNA methylation patterns. Recently, DNA methylation patterns have been found to correspond with specific tissue types in particular regions of DNA. Two markers, B_SPTB_03 and DDX4 have been effective in differentiating sperm from other tissue …
