Aggressive Reality Docuseries And Cyberbullying: A Partial Test Of Glaser’S Differential Identification Theory, J. Ra’Chel Fowler, Darren R. Beneby, Kenethia L. Fuller

International Journal of Cybersecurity Intelligence & Cybercrime

Reality docuseries have dominated primetime airwaves for the greater part of three decades. However, little is known about how viewers who are enamored with the genre’s most aggressive characters are influenced. Using Glaser’s (1956) theory of differential identification, this study employs survey data from 210 college students at a historically Black college and university to explore whether identification with characters from aggressive reality docuseries (ARDs) and the frequency of viewing ARD are positively associated with cyberbullying. Results of multivariate analyses revealed that men were more likely than women to publicly shame others and air other’s dirty laundry online. Additionally, the …

Kerberoasting: Case Studies Of An Attack On A Cryptographic Authentication Technology, D Demers, Hannarae Lee

International Journal of Cybersecurity Intelligence & Cybercrime

Kerberoasting, an attack vector aimed at the Kerberos authentication protocol, can be used as part of an adversary’s attack arsenal. Kerberos is a type of network authentication protocol that allows a client and server to conduct a mutual verification before providing the requested resource to the client. A successful Kerberoasting attack allows an adversary to leverage the architectural limitations of Kerberos, providing access to user password hashes that can be subject to offline cracking. A cracked user password could give a bad actor the ability to maintain persistence, move laterally, or escalate privileges in a system. Persistence or movement within …

Method Optimization For The Determination Of Cannabinoids In Blood By Liquid Chromatography Tandem Mass Spectrometry (Lc-Ms/Ms), Kevin D. Carrera

Student Theses

Delta-9-tetrahydrocannabinol (THC) continues to be one of the most popular drugs in the USA. Along with THC, other cannabinoids such as cannabidiol (CBD), are on the rise due to an increase in medicinal usage as well as the passage of different legislations removing these products from their current schedule I status. Thus, an urgency exists to develop robust and sensitive analytical methods to determine cannabinoids, especially THC, CBD and metabolites, in biological samples. The purpose of this study was to investigate different analytical procedures to determine the best method to identify and quantify CBD, THC and their metabolites in whole …

Seasonal Effects On The Arrival And Colonization Of Blow Flies (Diptera: Calliphoridae) On Carrion In New Jersey, Amanda A. Hernandez

Student Theses

Blow flies (Order: Diptera, Family: Calliphoridae) are a valuable forensic tool. Female blow flies will lay eggs (colonize) on remains often within minutes of death and entomological methods are based on their behavior and development to extrapolate postmortem intervals (PMI). External factors, such as temperature and weather patterns can influence timing of this behavior. This study seeks to gain a better understanding of the environmental factors that impact this behavior across two seasons. In this study, arrival and colonization behavior was investigated on rat carcasses from sunrise to sunset in a semi-rural region of New Jersey (n=64). Video recording software …

Examination Of Kastle-Meyer’S Limit Of Detection And Cross Reactivity, Djonnique M. Devone

Forensic Science Master's Projects

Forensic Serology is a branch of forensic science that deals with the identification of certain trace evidence. Blood is the most commonly recovered and most important piece of evidence analyzed and used in criminal investigations. As evidence blood holds significance in criminal investigations because it can link a crime to an individual or exclude their involvement. Serology and DNA analysis are often aligned, because the same evidence item is often analyzed by both sections. During a criminal investigation it is important for to identifying the type of biological material or trace evidence found. The possible identification of bodily fluids can …

Csi Effect: Exploring Impact Among Mississippi Lawyers, Jennie Odom

Honors Theses

The “CSI Effect” suggests that a growing number of jurors often have unrealistic expectations concerning the amount of forensic evidence which should be reasonably presented to convict an alleged criminal, and this misconception arises from watching heavily dramatized crime shows such as the CSI franchise. While many scholars have examined the CSI Effect, one critical perspective is often missing from the existing literature, that of the lawyers. Therefore, this project worked to explore the perspectives of both defense attorneys and prosecutors. Personal interviews were conducted to gain insight and perspective regarding the CSI Effect, whether these perspectives had impacted the …

A Comparison Of Methods Used For The Elimination Of Organics From Soil Prior To Analysis By Ftir-Atr And Sem-Eds, Argeliz Pomales

Student Theses

This project suggests improvements to the treatment methods utilized for the sample preparation and evaluation of minerals in soil samples encountered in forensic science casework and research. The evaluation of pre-treated and post-treated soil samples were performed using Fourier-Transform Infrared Spectroscopy with Attenuated Total Reflection (FTIR-ATR) and Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). Because soil samples contain a significant amount of organic matter and water which interfere with examination of these minerals while using these instruments, pretreatment methods are necessary to isolate the mineral fraction for examination and analysis.

Soil samples were first sieved with various size stainless steel mesh …

Effects Of External Decontamination Of Methamphetamine In Juvenile Hair, Rebecca Mitrani

Student Theses

Methamphetamine is a common illicit substance abused in the United States. Hair is one matrix that is analyzed to determine the presence and concentration of methamphetamine. When hair is analyzed, an external decontamination step is commonly performed prior to drug extraction to avoid a potential positive result from environmental exposure in someone that has not ingested the drug themselves. In child-custody scenarios, however, it is important to know if a child is often around such illicit substances. This study serves to assess if there is a significant difference in methamphetamine concentrations in samples from children up to 12 years old …

Investigating The Mechanisms Driving Mercury Reduction And Emissions In Soil, Hamil Patel

Student Theses

The water-induced emission of mercury from soil has been studied, but a complete understanding of the mechanisms driving mercury reduction and emission in soil has not been reached. The current understanding is an immediate expulsion of soil gaseous mercury upon water treatment and an upward transport of dissolved soil ionic mercury as the water evaporates. We analyzed emissions from several types of samples using various methods to further our understanding on the mechanisms involved. Light-induced emissions from aqueous samples of humic acid (HA) spiked with mercury (II) chloride (HgCl₂) showed that at higher concentrations of HA, less mercury …

Elisa Validation Method For The Detection Of Ketamine In Hair, Daria A. Centonza

Student Theses

An ELISA method was developed and validated to detect ketamine in human hair samples. Ketamine is an anesthetic drug that causes memory loss, dissociative sensations, and hallucinations. Due to these adverse effects, ketamine is a common drug used in drug facilitated sexual assaults (DFSAs). It is very important to be able to detect the substances used in DFSAs over a longer period of time due to the delayed reporting of these crimes. Victims, often out of fear and from the sedative/memory loss effects of the drugs, tend to report these crimes when it is too late to use urine and …

Evaluation Of Raman Spectroscopy As A Screening Tool To Predict Dna Recovery Potential In Skeletonized Human Remains, Cody Silverman

Honors Theses

The purpose of this study is to determine if Raman spectroscopy can be used as a rapid and non-destructive screening tool to predict DNA recovery potential for bone, and to explore the correlation between the compositional microstructure of bone and preservation of DNA. The two primary structural components of bone are calcium hydroxyapatite and collagen. It is proposed that by analyzing bone using Raman spectroscopy, the presence, state, and distribution of hydroxyapatite and collagen can be measured, which may be useful in predicting if the sample is viable for DNA analysis. The ultimate goal of this study is to develop …

An Investigation Of The Effect Of Temperature And Humidity On The Formation Of Antemortem Root Banding, Mae Griffin

Honors Theses

Microscopical hair analysis has become a controversial practice within forensic science primarily due to issues related to interpretation, and specifically overstating the significance of an association. The validity of microscopical hair comparisons has suffered from intense scrutiny by the forensic community, with one criticism being a paucity of peer reviewed research. An often-unrecognized aspect of microscopical hair analysis is its use in providing reconstructive information based on identifiable features. One example of this is postmortem root band or PMRB. PMRB is the formation of a band slightly above the root bulb and below the skin surface on the hair of …

Effect Of Coastal Environments On The Post Mortem Interval Of A Pig Carrion: Implications For Human Decomposition, Morgan Hough

Honors Theses

Forensic taphonomy involves the use of forensic techniques to determine the post mortem interval of a corpse. There are many factors that are known to influence the rate of decomposition, such as the temperature, season, soil type, moisture potential of the soil, and presence of insects or other decomposers. Previous studies in this field have focused primarily on decomposition patterns in mountainous environments in terms of terrestrial habitats or strictly aquatic environments, leaving this particular aspect of coastal settings to be unexplored.

To study these effects, the superior portion of a female pig was buried in sandy soil in mid-October …

Increasing Gas Chromatography-Flame Ionization Detection Sensitivity For Carfentanyl Detection: An Examination Of Procaine At Different Concentrations And Split Ratios, Sonalia T. Balli

Student Theses

An opioid abuse crisis in recent years has contributed to many overdoses and overdose-related deaths in the United States. In 2017, fentanyl and fentanyl analogs contributed to more than half of NYC’s overdose deaths in 2017. Carfentanyl – an extremely dangerous fentanyl analogue 100 times more potent than fentanyl – is very difficult to detect in drug samples because it is typically present in concentrations lower than analytical instruments can detect at standard settings. In this work, I hypothesize that gas chromatography-flame ionization detection (GC-FID), when optimized for the detection of carfentanyl by adjusting the split ratio, is more sensitive …
