13. Interviewing Children., Thomas D. Lyon Nov 2009

13. Interviewing Children., Thomas D. Lyon

Thomas D. Lyon

There is sufficient empirical evidence and consensus to begin to build guidelines, including the interview structure, setting, interviewer demeanor, children's reluctance and suggestibility, rapport development, narrative practice, introducing the topic of abuse, avoiding concepts that confuse children, instructions to children, phrasing of questions, evidence-based strategies for eliciting details, and multiple interviews.


12. Disclosure Of Child Sexual Abuse., Thomas D. Lyon, Elizabeth C. Ahern Oct 2009

12. Disclosure Of Child Sexual Abuse., Thomas D. Lyon, Elizabeth C. Ahern

Thomas D. Lyon

The research supports the proposition that CSA victims often delay disclosure or fail altogether to disclose abuse and that delays and nondisclosure are most common among children abused by a familiar person, especially a family member living in the child's household. The implications of the research are that inconsistencies and recantations in children's reports may be due to reluctance rather than a false allegation.

Tattoos Of Girls Under Pimp Control & Pimp Rules For The Control Of Victims, Donna M. Hughes Dr. Aug 2009

Tattoos Of Girls Under Pimp Control & Pimp Rules For The Control Of Victims, Donna M. Hughes Dr.

Donna M. Hughes

I have been collecting evidence of pimps’ practice of tattooing victims for several years. Tattooing, and sometimes branding or scarification, are marks of ownership. It is one of the ways that pimps maintain physical and psychological control over emotionally vulnerable girls. The girls and young women are frequently tattooed with the initials or street names of pimps. Marks also include gang symbols and $ signs or other symbols for the money the girls earn for the pimp. 


Does Anyone Get Stopped At The Gate? An Empirical Assessment Of The Daubert Trilogy In The States, Eric Helland, Jonathan Klick Mar 2009

Does Anyone Get Stopped At The Gate? An Empirical Assessment Of The Daubert Trilogy In The States, Eric Helland, Jonathan Klick

All Faculty Scholarship

The Supreme Court’s trilogy of evidence cases, Daubert, Joiner, and Kumho Tire appear to mark a significant departure in the way scientific and expert evidence is handled in federal court. By focusing on the underlying methods used to generate the experts’ conclusions, Daubert has the potential to impose a more rigorous standard on experts. Given this potential, some individuals have called for states to adopt the Daubert standards to purge “junk science” from state courts. However, there is relatively little empirical support for the notion that Daubert affects the quality of expert evidence. Using a large dataset of state court …


20. Maltreated And Non-Maltreated Children’S Evaluations Of Emotional Fantasy., Nathalie Carrick, Thomas D. Lyon, Jodi A. Quas Jan 2009

20. Maltreated And Non-Maltreated Children’S Evaluations Of Emotional Fantasy., Nathalie Carrick, Thomas D. Lyon, Jodi A. Quas

Thomas D. Lyon


Objectives: The purpose of the study was to examine differences between maltreated and nonmaltreated children’s ability to differentiate emotionally evocative fantastic and real events.
Methods: Four- and 5-year-old (n = 145) maltreated and nonmaltreated children viewed images depicting positive and negative fantastic and real events and reported whether the events could occur in real life and how the images made them feel. Children also completed a measure of verbal ability.
Results: Maltreated children were more accurate than nonmaltreated children in stating that negative real events could occur, but less accurate in stating that frightening fantastic events …


Twenty-First Century Forensic Science Challenges For Trial Judges In Criminal Cases: Where The "Polybutadiene" Meets The "Bitumen", Hon. Donald E. Shelton Jan 2009

Twenty-First Century Forensic Science Challenges For Trial Judges In Criminal Cases: Where The "Polybutadiene" Meets The "Bitumen", Hon. Donald E. Shelton

Hon. Donald E. Shelton

This artice discusses the challenges faced by trial judges in crimnal cases in fulfilling their Daubert "gatekeeping" role in the face of rapid advancements in forensic science. Admissibility questions for various forms of scientific evidence are reviewed, from DNA to fingerprints to social science "syndrome" evidence. The article discusses the pretrial issues presented by DNA databases, search issues and limitations problems as well as the impact of forensic science developments on juror expectations. Finally, forensic science issues regarding trial conduct are discussed, including voir dire, arguments and jury instructions,


The Death Of The American Trial, Robert P. Burns Jan 2009

The Death Of The American Trial, Robert P. Burns

Faculty Working Papers

This short essay is a summary of my assessment of the meaning of the "vanishing trial" phenomenon. It addresses the obvious question: "So what?" It first briefly reviews the evidence of the trial's decline. It then sets out the steps necessary to understand the political and social signficance of our vastly reducing the trial's importance among our modes of social ordering. The essay serves as the Introduction to a book, The Death of the American Trial, soon to be published by the University of Chicago Press.


On Race Theory And Norms, Christian Sundquist Jan 2009

On Race Theory And Norms, Christian Sundquist

Articles

This article has been adapted from an address given at the Albany Law Review Symposium in Spring 2009. This article discusses the judicial acceptance of DNA random match estimates, which uses DNA analysis to estimate the likelihood that a criminal defendant is the source of genetic material that is found at a crime scene. Relying on race, these tests demonstrate how such a re-inscription of race as a biological entity threatens the modern conception of race as a social construction, and how those estimates should be rejected as inadmissible on a doctrinal level under the Federal Rules of Evidence.


How Accountability-Based Policing Can Reinforce - Or Replace - The Fourth Amendment Exclusionary Rule, David A. Harris Jan 2009

How Accountability-Based Policing Can Reinforce - Or Replace - The Fourth Amendment Exclusionary Rule, David A. Harris

Articles

In Hudson v. Michigan, a knock-and-announce case, Justice Scalia's majority opinion came close to jettisoning the Fourth Amendment exclusionary rule. The immense costs of the rule, Scalia said, outweigh whatever benefits might come from it. Moreover, police officers and police departments now generally follow the dictates of the Fourth Amendment, so the exclusionary rule has outlived the reasons that the Court adopted it in the first place. This viewpoint did not become the law because Justice Kennedy, one member of the five-vote majority, withheld his support from this section of the opinion. But the closeness of the vote on …


A Witness To Justice, Jessica Silbey Jan 2009

A Witness To Justice, Jessica Silbey

Faculty Scholarship

In the 1988 film The Accused, a young woman named Sarah Tobias is gang raped on a pinball machine by three men while a crowded bar watches. The rapists cut a deal with the prosecutor. Sarah's outrage at the deal convinces the assistant district attorney to prosecute members of the crowd that cheered on and encouraged the rape. This film shows how Sarah Tobias, a woman with little means and less experience, intuits that according to the law rape victims are incredible witnesses to their own victimization. The film goes on to critique what the right kind of witness would …


Optimization Of The Microprecipitation Procedure For Nuclear Forensics Applications, Lyndsey Renee Kelly Jan 2009

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 …

10. Witnesses, Children As Legal., Thomas D. Lyon Dec 2008

10. Witnesses, Children As Legal., Thomas D. Lyon

Thomas D. Lyon

Child witnesses present challenges for both law and psychology. The question is how to elicit statements from children without sacrificing the truth, the rights of those against whom the child is testifying, and the welfare of the child.


11. Abuse Disclosure: What Adults Can Tell., Thomas D. Lyon Dec 2008

11. Abuse Disclosure: What Adults Can Tell., Thomas D. Lyon

Thomas D. Lyon

This book chapter reviews 14 retrospective surveys inquiring into respondent’s child abuse experiences and whether they ever disclosed abuse as children. I discuss the advantages of retrospective surveys (representativeness, reduced likelihood of false allegations, reduced suspicion bias). However, I also emphasize the likelihood of survey reluctance, and explain how this biases upwards estimates of abuse victims’ prior disclosure. If respondents who previously disclosed abuse are more likely to acknowledge abuse to a surveyor than respondents who never previously disclosed abuse, respondents who acknowledge abuse are disproportionately likely to be those who have previously disclosed. Difficulties notwithstanding, the research supports the …

9. Authors’ Response To Vieth, Thomas D. Lyon

Thomas D. Lyon

In 2007, Lamb, Orbach, Hershkowitz, Esplin, and Horowitz published in Child Abuse & Neglect a review of empirical research on the National Institute of Child Health and Development (NICHD) Investigative Interview Protocol in which they provided extensive research supporting the conclusion that the NICHD Protocol “comprises a useful and usable set of guidelines that allow trained interviewers to conduct investigative interviews that hew more closely than they otherwise would to universally endorsed professional guidelines” (p. 1212).


19. Young Children’S Competency To Take The Oath: Effects Of Task, Maltreatment, And Age., Thomas D. Lyon, Nathalie Carrick, Jodi A. Quas Dec 2008

19. Young Children’S Competency To Take The Oath: Effects Of Task, Maltreatment, And Age., Thomas D. Lyon, Nathalie Carrick, Jodi A. Quas

Thomas D. Lyon

This study examined maltreated and non-maltreated children’s (N = 183) emerging understanding of ‘‘truth’’ and ‘‘lie,’’ terms about which they are quizzed to qualify as competent to testify. Four- to six-year-old children were asked to accept or reject true and false (T/F) statements, label T/F statements as the ‘‘truth’’ or ‘‘a lie,’’ label T/F statements as ‘‘good’’ or ‘‘bad,’’ and label ‘‘truth’’ and ‘‘lie’’ as ‘‘good’’ or ‘‘bad.’’ The youngest children were at ceiling in accepting/rejecting T/F statements. The labeling tasks revealed improvement with age and children performed similarly across the tasks. Most children were better able to evaluate ‘‘truth’’ …
