Biogeographic Affiliation And Centers Of Richness As Predictors Of Elevational Range-Size Patterns For Malesian Flora, Melissa Whitman, Sabrina E. Russo

School of Biological Sciences: Faculty Publications

Our goal was to interrogate the idea that “mountain passes are higher in the tropics” by investigating ecological and biogeographic drivers of elevational range-sizes patterns among equatorial flora. We used herbarium records for 60 species-rich plant families, representing 18 535 species total, to estimate distributions over a 4500 m elevational gradient. For each family, we estimated the change in average range-sizes with increasing elevation (i.e. Rapoport's rule, abbreviated as ERR) and quantified 15 metrics of familial richness distribution, evolutionary age, and biogeographic affiliation. We visualized covariation across families using phylogenetic principal components analysis (pPCA). We then evaluated how family-level ERR …

Against Gap-Filling, Noah C. Chauvin

Cardozo Law Review de•novo

Legal scholars delight in gap-filling. They frequently claim that their works have identified a gap in the literature and to have filled (or begun filling) that gap. However, all too often, these same papers fail to explain why the gap needed to be filled at all. Indeed, despite a robust tradition of meta-scholarship, the legal literature is largely devoid of a theory of academic gap-filling. This essay fills that gap, arguing that gap-filling for the sake of gap-filling is an error for three interconnected reasons. First, gaps might exist for a good reason. Second, concern with gap-filling is often a …

Reforming Informed Consent To Include Comprehension: A Proposal To Promote Equity In Medical Decision-Making, Valerie Gutmann Koch

Cardozo Law Review de•novo

The ethical goals of the legal doctrine of informed consent are lofty. The law requires that clinicians explain the risks, benefits, and alternatives of proposed treatments to patients, and to respect patient autonomy through voluntary, informed medical decisions aligned with individual values and preferences. Yet in practice, patients often struggle to comprehend the risks and alternatives of a proposed medical intervention. Since investigators began analyzing the sufficiency of informed consent, it has been recognized that the current rules, which focus solely on clinical disclosures, are inadequate in addressing disparities associated with education, race/ethnicity, and age. Despite technically “adequate” disclosures under …

Meaningful Or Meaningless? The Temporal Scope Of The Constitutional Right Of Access To Courts For Incarcerated Litigants, Alison Aimers

Cardozo Law Review de•novo

This Note will advocate for the position taken by the Third and Seventh Circuits that incarcerated individuals’ right to affirmative assistance in accessing legal materials extends past the pleading stage to all stages of civil rights claims and post-conviction criminal appeals. U.S. Supreme Court precedent supports this position, and judicial clarity on this issue is required to best protect the constitutional right of access in light of significant existing barriers to incarcerated litigants’ access to courts.

Harnessing Hypocrisy: A Crack In The Supreme Court’S Colorblindness Mask, Zamir Ben-Dan

Cardozo Law Review de•novo

This Essay contends that the Supreme Court’s denial of certiorari in Harness v. Watson stands as a testament to its hypocrisy. The day after the Court professed an allegiance to promoting racial equality in Students for Fair Admissions, Inc. v. President and Fellows of Harvard College, it refused to even consider invalidating a clear barrier to racial equality. The day after the Court struck down a remedy designed to address a long, sad, and painful history of racism, the Court left undisturbed an obvious symbol of this long, sad, and painful history of racism. When juxtaposed against both the denial …

Expanding Homicide Liability For A Parent’S Omission, Monu Bedi

Cardozo Law Review de•novo

Earlier this year, Jennifer and James Crumbley were convicted of manslaughter and sentenced to 10-15 years for not stopping their teenage son, Ethan, from killing four students at his high school. This is the first known occurrence of an American prosecutor obtaining a homicide conviction relying on a parental omission—or failure to act—where the victim was not the parent’s own child. Parental omissions historically have only triggered homicide charges if the parent fails to protect their child, not others, from harm. Unlike the general population, parents owe a special duty to their child because they are the ones tasked to …

Justice Over Finality: Compassionate Release As A Mechanism To Correct Sentencing Errors, Eliza Stup

Cardozo Law Review de•novo

The passage of the First Step Act of 2018 provoked a wave of scholarship analyzing the impact of the Act on compassionate release. However, little attention has been paid to the newfound potential for sentencing errors to fit within the compassionate release framework. This Note addresses a federal circuit split over the legality of sentencing errors as a ground for compassionate release. Drawing on statutory text, legislative history, and recently promulgated U.S. Sentencing Commission guidelines, this Note seeks to provide a robust defense for judicial discretion to consider sentencing errors as a basis for compassionate release. Sentencing errors represent a …

Comparative Analysis Of Prosecutor-Led Diversion Programs: Insights To Japan’S Suspension Of Prosecution For Recidivism Prevention, Mio Hagino

LL.M. Essays & Theses

Around 60% of all crimes in Japan are committed by repeat offenders, and therefore preventing recidivism is a central concern in Japan. Recognizing the importance of early intervention, some prosecutors’ offices collaborate with social workers and provide necessary measures for recidivism prevention when prosecution is suspended. To promote prosecutor-led recidivism prevention, there is an ongoing discussion to legislate the approach currently taken by prosecutors’ offices. However, concerns remain about procedural fairness, transparency of prosecutorial discretion, and collaboration with other agencies. In the United States, prosecutor-led diversion programs are adopted in many states, with ongoing research on their effectiveness and challenges. …

The End Of Consent: Data And The Corporate-Consumer Relationship, Faisal Hijjawi

LL.M. Essays & Theses

Consumer data is largely regulated through the notice-and-choice approach in the United States, which relies on consumer consent. The notice-and-choice approach is rooted in the control theory of information privacy. This paper will argue that the control theory is limited due to its reliance on property law, its breadth, as well as it reinforcing the ‘no privacy in public’ concept. Further, the notice-and-choice approach relies on consent being both free and informed. However, consent cannot be considered free due to the lack of choice and the manipulation exerted on the consumer. Also, consent is not informed as the consumer lacks …
