A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …

Eroding Protections: The Decline Of Miranda Rights And Its Impact On Due Process In Contemporary America, Autumn G. Pelfrey

Honors Undergraduate Theses

This thesis examines whether the protections established in Miranda v. Arizona, 384 U.S. 436 (1966), remain robust within contemporary criminal justice practice or have been weakened through doctrinal and practical developments. Miranda warnings were originally designed to mitigate the risk that coercive custodial interrogation would produce compelled or unreliable self-incrimination. Since 1966, however, both judicial interpretation and evolving law-enforcement practices have created a growing gap between Miranda’s formal legal promise and its practical operation in real-world interrogations.

The study evaluates the erosion of Miranda’s protective force through three primary mechanisms. First, doctrinal developments have narrowed Miranda’s scope by redefining …

Policy Recommendations To Reduce False Confessions By Juveniles In Wrongful Conviction Cases, Rohit R. Iyer

CMC Senior Theses

This research focuses on false confessions by juveniles in the United States justice system. False confessions are statements made by suspects during investigations in which individuals provide statements to investigators admitting to a crime in which they had no part. In these cases, individuals often spend years, if not the entirety, of their lives behind bars for crimes they did not commit. False confessions are the result of a number of systemic factors that will be discussed in this paper. While relatively rare, they are one of the largest blemishes in the U.S. justice system. Juveniles – individuals below the …

Cyanoacrylate Deposition Onto Sebum With Pretreatment Of Amine, Isaac Baltz

Chemistry & Biochemistry Undergraduate Honors Theses

Super glue, or ethyl cyanoacrylate, fuming is commonly used in forensic science to develop latent fingerprints on nonporous surfaces[7]. Fingerprints are primarily made up of the oily substance secreted by sebaceous glands better known as sebum. Previously it has been shown that exposure of fingerprints to diisopropylamine dramatically increases the deposition of cyanoacrylate polymers on the fingerprints[1]. However, the heterogeneity of any series of real fingerprints made it difficult to quantitatively assess this effect. This heterogeneity includes not just the amount of sebum but the presence of unknown amounts of proteins, amino acids, and other potential nucleophiles which catalyze the …

An Archival Exploration Of Lineup Fairness In Eyewitness Research, Phoebe Kane

Student Theses

In this study, we were interested in investigating if the Betaface facial analysis program reliably predicts eyewitness lineup choosing behavior. If face analysis programs are as good or better than human judgements, using them could be a reliably more efficient, reproducible, and equitable basis for choosing fillers and evaluating lineup fairness. We collected 27 datasets from eyewitness researchers and analyzed them to produce Betaface similarity values, which measured the similarity between all the photos in each array. We compared these Betaface data to the identification data from the original studies. Our analysis of the arrays via Betaface yielded data with …

Lineups, Showups, And Simultaneous Showups: A Replication And Extension Of The Red Box Study, Lana Dranow

Psychological Science Undergraduate Honors Theses

The reliability of eyewitness identification procedures and the following testimony in a court of law has been highly contested in recent decades. There are two main types of identification procedures most commonly used by law enforcement officers in the United States: lineups and showups. Prior research has indicated that lineups consistently yield the most accurate identifications due to the presence of fillers (plausible alternatives to a suspect) alongside the suspect when compared to showups. This is commonly attributed to two main theories- filler siphoning theory and diagnostic feature detection theory. In a study conducted by Colloff and Wixted (2020), researchers …

The Contribution Of Forensic Science To Wrongful Convictions: An Analysis Of Forensic Expert Testimony, Parker Gunter

Honors Theses

The purpose of this study was to explore the progression and potential improvement of forensic science in court.

Omar Effendi Vs. Union Fenosa: Corruption As A Transnational Public Policy Consideration, Ahmed Badr Eldin

Theses and Dissertations

At the beginning of 2011, Egypt witnessed radical political developments that led to the emergence of a pressing tendency to adjudicate the collapsed regime’s policies and practices. Shortly thereafter, the Egyptian State Council issued a number of judicial decisions that confirmed that the sale of the privatized governmental enterprises had been tainted by corruption. Crucially, the Court maintained that flagrant breach of law, regulations, and administrative orders that encompassed these transactions created serious suspicions about corruption committed by public officials and investors. It concluded that the existence of corruption, as a transnational public policy consideration, had deprived foreign investors of …

Evaluating A Test For Shedding Propensity Using Tape Lifts From Different Skin Locations, Xiao M. Chen

Student Theses

The shedding propensity of a person can assist data interpretation in casework when assessing the possibility of passive transfer for DNA analysis. Past studies on shedding propensity evaluated palmar skin (washed and unwashed) deposits. This study compared different skin locations with respect to shedding propensity, and explored the potential of tape-lifts as a skin surface collection method. Eight different skin types and samples were collected with adhesive tape disks from 28 participants over three non-consecutive days; the washed and unwashed fingers from both hands, toe, and arm, neck below ear, and nape. Samples were extracted, quantified, amplified, genotyped, and evaluated …

The Right Against Self-Incrimination Under Indian Constitution & The Admissibility Of Custodial Statements Under The Indian Evidence Act, 1872, Khagesh Gautam

Maurer Theses and Dissertations

This work argues that the constitutional validity of section 27 of the Indian Evidence Act, 1872 is highly suspect on the ground that it violates the right against self-incrimination protected by article 20(3) of the Indian Constitution. Section 27 codifies the doctrine of confirmation by subsequent recovery, an old British rule of admission according to which self-incriminatory custodial statements and/or confessions obtained by the police or the investigation agency are admissible into evidence on the ground that contents of such statement have been confirmed by recovery of incriminating physical evidence. Chapter I locates the Indian criminal justice system within the …

Neither “Post-War” Nor Post-Pregnancy Paranoia: How America’S War On Drugs Continues To Perpetuate Disparate Incarceration Outcomes For Pregnant, Substance-Involved Offenders, Becca S. Zimmerman

Pitzer Senior Theses

This thesis investigates the unique interactions between pregnancy, substance involvement, and race as they relate to the War on Drugs and the hyper-incarceration of women. Using ordinary least square regression analyses and data from the Bureau of Justice Statistics’ 2016 Survey of Prison Inmates, I examine if (and how) pregnancy status, drug use, race, and their interactions influence two length of incarceration outcomes: sentence length and amount of time spent in jail between arrest and imprisonment. The results collectively indicate that pregnancy decreases length of incarceration outcomes for those offenders who are not substance-involved but not evenhandedly -- benefitting white …

Virtual Hearings And Blockchain Technology Solutions In Criminal Law, Chantell Bergquist

Political Science Theses and Capstones

Technology has evolved and raided our personal and professional lives. Although the courts are not immune to the advancement and integration of technology, the courts are not keeping up with relevant technological advancements. Historically, courts have been hesitant to embrace new technologies despite the Federal Rules of Civil Procedure and the American Bar Association Model Rules of Professional Conduct. Rule 1 of the Federal Rules of Civil Procedure creates the right to a “just, speedy, and inexpensive determination of every action and proceeding.” Likewise, the American Bar Association Model Rules of Professional Conduct have determined attorneys must “keep abreast of …

Bait Questions As Source Of Misinformation In Police Interviews: Does Race Or Age Of The Suspect Increase Jurors' Memory Errors?, Matilde Ascheri

Student Theses

Bait questions—hypothetical questions about evidence, often used by detectives during interrogations—can activate the misinformation effect and alter jurors’ perceptions of the evidence of a case. Here, we were interested in investigating whether mock jurors’ implicit biases could amplify the magnitude of the misinformation effect. We accomplished this by manipulating the age and race of the suspect being interrogated. As an extension of Luke et al. (2017), we had participants read a police report describing evidence found at a crime scene, then read a transcript of a police interrogation where the detective used bait questions to introduce new evidence not presented …

The Virtue Of Process: Finding The Legitimacy Of Judicial Fact-Finding In Personal Injury Litigation, Nayha Acharya

PhD Dissertations

This thesis is an inquiry into the legitimacy of judicial fact-finding in civil litigation. Judges make authoritative factual findings in conditions of uncertainty and the decision-making process cannot, and does not, guarantee the accuracy of those outcomes. Given the inevitable risk of error, on what basis is the authority of judicial fact-finding legitimate? This project provides a framework of procedural legitimacy that bridges two unavoidable aspects of adjudication: factual indeterminacy and the need for justifiably authoritative dispute resolution. This work draws of the legal theories of Lon Fuller and Jurgen Habermas to substantiate the notion of procedural legitimacy in the …

Section 2 analyses the difference between the hearsay rules historical rationale and the application of the exclusionary hearsay rule. Section 3 analyses the difference between the hearsay rules historical rationale and the application of some categorical hearsay exceptions.

Overall, the thesis finds that the hearsay rules historical rationale has three aspects: concern with the inherent reliability of hearsay evidence, concern with procedural …

What Judges Say And Do In Deciding National Security Cases: The Example Of The State Secrets Privilege, Anthony John Trenga

Duke Law Master of Judicial Studies Theses

From the criminal trial of Aaron Burr on charges of treason to modern-day litigation involving the CIA, the state secrets privilege presents a thorny issue for federal judges. Judge Trenga examines the legal issues at the heart of this privilege—separation of powers, non-justiciability, evidentiary privilege, national security interests, and military secrets—and the two primary doctrinal tracks judges invoke. Then, based on interviews with thirty-one federal judges, Judge Trenga offers insights into how judges think about applying the state secrets privilege to sensitive material.

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 …

The Exclusion Of Improperly Obtained Evidence At The International Criminal Court: A Principled Approach To Interpreting Article 69(7) Of The Rome Statute, Michael Madden

LLM Theses

This thesis examines article 69(7) of the Rome Statute, which creates an exclusionary rule for improperly obtained evidence at the International Criminal Court (ICC). Ultimately, the thesis proposes how the ICC should interpret its exclusionary rule. The thesis discusses the theory underlying exclusionary rules, the evidence law and remedial law contexts within which exclusionary rules operate, and numerous comparative examples of exclusionary doctrine from within national criminal justice systems. Finally, some unique aspects of international criminal procedure are described in order to demonstrate how an international exclusionary rule might need to differ from a domestic rule, and previous jurisprudence relating …

Juror Perceptions Of Eyewitness Identification Evidence, Timothy G. Wykes

Theses and Dissertations (Comprehensive)

Jurors rely on eyewitness testimony in deciding a defendant’s guilt or innocence. Archival analyses of hundreds of post-conviction DNA exonerations have identified eyewitness misidentification as the highest individual factor contributing to wrongful convictions (Innocence Project, 2014). Internationally, criminal justice systems have employed procedural safeguards (PSs) to educate juries on factors affecting eyewitness identification accuracy. Two such safeguards include the introduction of eyewitness expert testimony during trial proceedings and the reading of cautionary instructions by a presiding judge. In an independent factorial design, this research sought to examine the effects of a model judicial caution drafted by the Ontario Judicial Council …

Science On Law's Terms: Implications Of Procedural Legitimacy On Scientific Evidence, Nayha Acharya

LLM Theses

Scientific evidence is relied on more and more in litigation. Discussions and debates aimed at enabling courts to make the best use scientific evidence are increasingly critical. This thesis adds the perspective of procedural legitimacy to the science and law discussion. Procedural Legitimacy is the concept that consistent adherence to legal procedure maintains the overall legitimacy of the legal system, and the validity of its outcomes. I argue that the integrity of legal procedures must be maintained where scientific evidence is presented, so that judicial decisions that rely on scientific evidence are legitimate.

Sex And The Supremes: Towards A Legal Theory Of Sexuality, Elaine Craig

PhD Dissertations

This thesis examines how the Supreme Court of Canada, across legal contexts, has tended to conceptualize sexuality. It focuses primarily on areas of public law including sexual assault law, equality for sexual minorities, sexual harassment and obscenity and indecency laws. There were a number of trends revealed upon reviewing the jurisprudence in this area. First, the Court’s decisions across legal contexts reveal a tendency to conceptualize sexuality as innate, as a pre-social naturally occurring phenomenon and as an essential element of who we are as individuals. This is true whether one is speaking of the approach to gay and lesbian …
