Putting The Microscope On Crime Labs: The Effects Of Evidence Complexity And Laboratory Type On Jurors' Perceptions Of Forensic Evidence, Miliaikeala S.J. Heen
Putting The Microscope On Crime Labs: The Effects Of Evidence Complexity And Laboratory Type On Jurors' Perceptions Of Forensic Evidence, Miliaikeala S.J. Heen
UNLV Theses, Dissertations, Professional Papers, and Capstones
An experiment was conducted to test the effects of evidence complexity and laboratory type on jurors' perceptions of forensic evidence. The study specifically focused on three types of labs: public labs, private labs, and "corporate labs." Public labs are managed by a federal, state, or local law enforcement agency, where evidence is usually analyzed internally at an agency. Private labs are those that have been formed as private businesses to provide services to federal, state, and local crime labs with overflow work. Corporate labs are managed by major retail corporations, and primarily service the needs of their store businesses, but …
Death And Politics: The Role Of Demographic Characteristics And Testimony Type In Death Penalty Cases Involving Future Dangerousness Testimony, Amy Magnus, Miliaikeala Heen, Joel D. Lieberman
Death And Politics: The Role Of Demographic Characteristics And Testimony Type In Death Penalty Cases Involving Future Dangerousness Testimony, Amy Magnus, Miliaikeala Heen, Joel D. Lieberman
Graduate Research Symposium (GCUA) (2010 - 2017)
Past research examining expert future dangerousness prediction testimony in death penalty cases and civil confinement hearings for sex offenders has found that jurors tend to be more persuaded by less scientific “clinical” testimony and less influenced by “actuarial” based testimony. Jurors demonstrate greater receptivity for clinical testimony despite the fact that actuarial testimony has been shown to be a better predictor of future dangerousness. Research in this area has focused on identifying cognitive factors that can potentially be manipulated during a trial to increase the effectiveness of actuarial testimony on jurors. A mock jury study was conducted to extend these …
Juror Typologies And Dna Comprehension:Who Benefits From Jury Trial Innovations?, Mari Sakiyama, Joel D. Lieberman
Juror Typologies And Dna Comprehension:Who Benefits From Jury Trial Innovations?, Mari Sakiyama, Joel D. Lieberman
Graduate Research Symposium (GCUA) (2010 - 2017)
When DNA evidence is presented in the courtroom, it is typically accompanied by complex testimony conveying information such as the method of generating population frequencies, match criteria and probabilities, as well as laboratory errors and error rates. Although this evidence may have high probative value, the legal community has expressed growing concern regarding jurors’ ability to comprehend it. However, courts have implemented a variety of jury trial innovations to facilitate jurors’ ability to process complex information. Although these innovations may have a positive effect on comprehension of complex trial evidence, it is unclear whether some jurors are more likely to …
Optimization Of The Microprecipitation Procedure For Nuclear Forensics Applications, Lyndsey Renee Kelly
Optimization Of The Microprecipitation Procedure For Nuclear Forensics Applications, Lyndsey Renee Kelly
UNLV Theses, Dissertations, Professional Papers, and Capstones
Microprecipitation has become one of the most widely used sample preparation techniques for alpha spectroscopy. Many factors during the precipitation process can affect the yield and energy resolution by adding unwanted mass to the sample. Current applications in nuclear forensics call for an optimization of energy resolution and yield in order to improve identification and quantify specific radionuclides. The purpose of this research is to determine the optimal parameters used for microprecipitation. The optimal solution temperature, precipitation time, carrier amount, and hydrofluoric acid amount are used to investigate the influence of varying the type of carrier, as well as, the …
