Detecting Child Sexual Abuse Images: Traits Of Child Sexual Exploitation Hosting And Displaying Websites, Enrique Guerra, Bryce G. Westlake
Detecting Child Sexual Abuse Images: Traits Of Child Sexual Exploitation Hosting And Displaying Websites, Enrique Guerra, Bryce G. Westlake
Faculty Research, Scholarly, and Creative Activity
Background
Automated detection of child sexual abuse images (CSAI) often relies on image attributes, such as hash values. However, electronic service providers and others without access to hash value databases are limited in their ability to detect CSAI. Additionally, the increasing amount of CSA content being distributed means that a large percentage of images are not yet cataloged in hash value databases. Therefore, additional detection criteria need to be determined to improve identification of non-hashed CSAI.
Objective
We aim to identify patterns in the locations and folder/file naming practices of websites hosting and displaying CSAI, to use as additional detection …

Determination Of Vehicle Speed From Recorded Video Using Reverse Projection Photogrammetry And File Metadata, Brandon Epstein, Bryce Westlake
Determination Of Vehicle Speed From Recorded Video Using Reverse Projection Photogrammetry And File Metadata, Brandon Epstein, Bryce Westlake
Faculty Publications
The prevalence of security and in‐car video has increased the number of motor vehicle accidents captured on digital video. However, inconsistencies in how to accurately determine time and distance for vehicle speed has led to examinations with varying results. A potential solution for calculating time intervals is to use frame timing contained within many digital video file's metadata, recorded with 0.000001 sec precision. This paper examines a fatal motor vehicle accident where frame timing information was used with distance measurements from reverse projection photogrammetry to calculate vehicle speed. A margin of error was then calculated based on the accuracy in …
Police Legitimacy In Trinidad And Tobago: Resident Perceptions In A High-Crime Community, Ericka B. Adams
Police Legitimacy In Trinidad And Tobago: Resident Perceptions In A High-Crime Community, Ericka B. Adams
Faculty Publications
Violent crime in Trinidad and Tobago has increased over the last two decades, yet the police have been largely unsuccessful in reducing violence. Between 1999 and 2016, the murder rate increased by 475%. Despite the fact that the murder rate has increased, approximately 76 homicides are cleared each year, resulting in a low-homicide clearance rate. Using 40 semi-structured interviews with community members from a high-crime, low-income community in Trinidad and Tobago, this study examines residents’ experiences with police officers, and respondents’ willingness to work with the police to clear criminal cases. The results indicate that due to a lack of …
The Impact Of Gangs On Community Life In Trinidad, Ericka Adams, Patrice Morris, Edward Maguire
The Impact Of Gangs On Community Life In Trinidad, Ericka Adams, Patrice Morris, Edward Maguire
Faculty Publications
Trinidad and Tobago has more than 100 criminal gangs, some of which engage in high levels of homicide and violence. Recent research has shown that gang members in Trinidad and Tobago are more likely than nongang members to be arrested for violent, property, and drug crimes. As gangs continue to proliferate throughout the Caribbean, there is a pressing need to understand the nature of these gangs and their impact on the communities in which they are entrenched. Using data from interviews with community members, police officials, and gang members, as well as ethnographic observations from 10 high crime, predominantly Black …
Hyperspectral Measurements Of Immature Lucilia Sericata (Meigen) (Diptera: Calliphoridae) Raised On Different Food Substrates, Jodie A. Warren, T. D. Pulindu Ratnasekera, David A. Campbell, Gail S. Anderson
Hyperspectral Measurements Of Immature Lucilia Sericata (Meigen) (Diptera: Calliphoridae) Raised On Different Food Substrates, Jodie A. Warren, T. D. Pulindu Ratnasekera, David A. Campbell, Gail S. Anderson
Faculty Research, Scholarly, and Creative Activity
Immature Lucilia sericata (Meigen) raised on beef liver, beef heart, pork liver and pork heart at a mean temperature of 20.6°C took a minimum of 20 days to complete development. Minimum development time differences within stages were observed between the meat types (pork/beef), but not the organ types (liver/heart). Daily hyperspectral measurements were conducted and a functional regression was completed to examine the main effects of meat and organ type on daily spectral measurements. The model examined post feeding larval spectral measurements of insects raised on beef liver alone, the effect of those raised on pork compared with those raised …
“I’Ve Risen Up From The Ashes That I Created”: Record Clearance And Gendered Narratives Of Self-Reinvention And Reintegration, Elsa Chen, Ericka Adams
“I’Ve Risen Up From The Ashes That I Created”: Record Clearance And Gendered Narratives Of Self-Reinvention And Reintegration, Elsa Chen, Ericka Adams

Record clearance allows some individuals to redesignate or remove certain minor convictions from their criminal records. This interview-based study finds that both men and women seek opportunities for personal gain through record clearance, but women are more motivated by moral and religious influences and concern about reputation. Women are also more likely than men to acknowledge personal flaws, and to desire to replace criminal identities with law-abiding identities. As women redefine their identities, caregiving is especially important as a personal obligation and professional aspiration. Record clearance is particularly compatible with women’s motivations, willingness to change, and personal and professional goals.

Hyperspectral remote sensing is an innovative technology with applications in many sciences and is a non-destructive method that may offer more precise aging within development stages. Hyperspectral reflectance measurements from the anterior, midsection, and posterior of Lucilia sericata (Meigen) larvae and pupae were conducted daily from samples of the developing insects beginning at second instar. Only midsection measurements were conducted on second instar larvae due to their size, to ensure that the measurement was not of reflective surroundings. Once measured, all insects were washed with deionized water, blotted with filter paper, and re-measured. Daily age prediction during the post-feeding stage …
Erasing The Mark Of A Criminal Past: Ex-Offenders’ Expectations And Experiences With Record Clearance, Ericka Adams, Elsa Chen, Rosella Chapman
Erasing The Mark Of A Criminal Past: Ex-Offenders’ Expectations And Experiences With Record Clearance, Ericka Adams, Elsa Chen, Rosella Chapman
Faculty Publications
Through the process of record clearance, individuals can have certain minor convictions removed from their criminal records or designated as expunged. This study analyzes data gathered from semi-structured interviews with 40 persons with past criminal convictions to examine the expectations of individuals who seek record clearance and the extent to which completion of the process facilitates efforts to reintegrate into society and desist from crime. The analysis finds that record clearance benefits ex-offenders through external effects, such as the reduction of barriers to employment, and internal processes, such as the facilitation of cognitive transformation and the affirmation of a new …

Effect Of Fluctuating Temperatures On The Development Of A Forensically Important Blow Fly, Protophormia Terraenovae (Diptera: Calliphoridae), Jodie-A. Warren, Gail S. Anderson
Effect Of Fluctuating Temperatures On The Development Of A Forensically Important Blow Fly, Protophormia Terraenovae (Diptera: Calliphoridae), Jodie-A. Warren, Gail S. Anderson
Faculty Research, Scholarly, and Creative Activity
Experiments were conducted to compare the immature development of Protophormia terraenovae (Robineau-Desvoidy) at fluctuating temperatures of 4-28 and 9-23°C to their mean constant temperature, 16°C. Overall development was fastest at the greater fluctuation and slowest at the constant temperature but showed similar percentages of development time in each stage. The rate summation effect is suspected to have caused this difference in development rate because fluctuations above the mean increase the rate relatively more than temperatures below the mean can lower the rate.

Establishing Lower Developmental Thresholds For A Common Blowfly: For Use In Estimating Elapsed Time Since Death Using Entomologyical Methods, Gail S. Anderson, Jodie-A. Warren
Establishing Lower Developmental Thresholds For A Common Blowfly: For Use In Estimating Elapsed Time Since Death Using Entomologyical Methods, Gail S. Anderson, Jodie-A. Warren
Faculty Research, Scholarly, and Creative Activity
Forensic entomology is a science used to estimate a post-mortem interval (PMI). Larvae develop at predictable rates and the time interval for this development can be used to estimate the PMI. Environmental temperatures are not constant and fluctuate with the photoperiod. In early and late insect seasons, temperatures can drop to below threshold temperatures where development essentially ceases. Threshold temperatures differ for different species and should be determined by raising insects at the extremely low temperatures. The lower threshold temperature for Protophormia terraenovae for egg hatch is 10.3°C ; for first instar larvae to molt to second instar larvae it …

A Comparison Of Development Times For Protophormia Terraenovae (R-D) Reared On Different Food Substrates, J.-A. Warren, G. S. Anderson
Faculty Research, Scholarly, and Creative Activity
Experiments were conducted to determine whether a specific larval substrate impacted immature development rates. Protophormia terraenovae was raised on beef organs and compared with whole carcasses (rat), to determine if discrepancies in development times were observed. The minimum development time on beef liver was the most consistent with the rat carcass but a significant difference between all substrates was found after the third instar. These differences can be explained by the differences found between heart and muscle and the other substrates. Often length of the larvae is used to estimate insect age and so Day 2 measuring of weight, length, …
