Using Pattern Area Ridge Flow In The Three Areas Of The Palm To Determine Classification Trends, Ashton Horton
Using Pattern Area Ridge Flow In The Three Areas Of The Palm To Determine Classification Trends, Ashton Horton
Honors Theses
Friction ridge skin is only located on the fingers, palms, and soles of feet. These ridges have been used to make identifications since before the twentieth century. These methods may be the basis of scientific testimony in court because of the amount of research that has been conducted in fingerprint identification. Courts uphold these techniques because of three principles behind fingerprint identification: fingerprints are unique because no two are the same, they will not change from the time they are formed in the womb until post-mortem decomposition, and they can be objectively classified using a general classification system. Little research …
Form-Blindness And Its Implications: A Verification Study, Meredith G. Moody
Form-Blindness And Its Implications: A Verification Study, Meredith G. Moody
Honors Theses
Form-blindness is not an eye problem. It is a perceptual inability to distinguish the small differences between shapes, colors, and patterns. This research examines this phenomenon by using a previously-established exam to study form-blindness and its implications. Demographic variables such as age, major, GPA, and sex are also looked at to see what potential impact they might have on a person’s performance on the exam. The form-blindness tests administered during this study were graded and then analyzed using descriptive statistics and multiple linear regression. In the end, no statistical significance was found for the demographic variables of age, GPA, major, …
A Validation Study Of Zar-Pro Fluorescent Blood Lifting Strips, Carter L. Depew
A Validation Study Of Zar-Pro Fluorescent Blood Lifting Strips, Carter L. Depew
Honors Theses
It is well known within the latent fingerprint discipline that collection of bloody impressions can be difficult and destructive. This pilot study aims to validate the use of Zar-Pro Fluorescent Blood Lifting Strips© in the collection of bloody fingerprint impressions, and then compare the technique outcomes that of the currently used method – photography. This study used both collection methods to extract bloody impressions from white copy paper and aluminum metal. The impressions were aged over a two-week period prior to collection. A numerical score – representative of the identifiable minutiae points – was then obtained using the Smart Extract …
Exploring The Perception Towards Enhancing Credentials By Certification Of Latent Fingerprint Examiners In The Southern United States, Christopher G. Brewer
Exploring The Perception Towards Enhancing Credentials By Certification Of Latent Fingerprint Examiners In The Southern United States, Christopher G. Brewer
Honors Theses
With several applications of forensic processes coming into question, becoming a reputable expert witness in a court of law can be dire. This pilot study explores the professional opinions of latent fingerprint examiners employed by state criminal investigation departments. Research was geared towards measuring the notion that gaining certification through institutions such as the International Association for Identification (IAI) aids in the perception of latent fingerprint examiners’ credibility and confidence as expert witnesses. The sample population of latent fingerprint examiners (LFPEs) was gathered using a digital survey issued to the forensic laboratories and divisions housed within state criminal investigation units. …
