Jurnal Hukum & Pembangunan

Strengthening idea of constitutional democracy as a transitional phase towards a modern rule of law requires one of main characteristics of an independent judiciary. Current phenomena demonstrate how utopian these conditions are as the judiciary becomes increasingly politically pragmatic, transactional, interdependent, and demoralized. At the same time, phenomenon of constitutional defiance is growing stronger with efforts to deconstitutionalize and politicize the judiciary. This study aims to explore the existence and legitimacy of the judiciary in constitutional democracy era against that phenomenon. The research was conducted doctrinally with a historical, conceptual, and comparative approach that was analyzed qualitatively. The results indicate …

Magang Atau Pekerja? Menggugat Status Abu-Abu Tenaga Paruh Waktu Mahasiswa Di Fakultas Hukum Ugm, Patricia Nerissa Krisna Putri, Markus Togar Wijaya

Jurnal Hukum & Pembangunan

This study highlights the controversy surrounding the change in nomenclature for student workers at Gadjah Mada University, particularly within the Faculty of Law. The status of these workers has shifted from 'part-time' to 'student intern'. This unilateral change has created a legal grey area that could lead to students being subjected to disguised employment practices. Using socio-legal research methods, this article examines the validity of the 'internship' status based on the elements of an employment relationship (work, orders and wages) within the labour law regime, analysing it using the theory of structural injustice. The research findings suggest that reclassifying part-time …

Super-Efficient Breach In Bankruptcy: Recalibrating Remedies For Contract Rejection Damages, Ishaq Kundawala

Emory Bankruptcy Developments Journal

Contract law rests on a simple but powerful premise: when a party breaches, the law protects the injured party’s expectation interest, placing them, as nearly as possible, in the position they would have occupied had the contract been performed. This principle underlies the theory of efficient breach, which tolerates economically rational breaches so long as the non-breaching party is fully compensated. But in bankruptcy, this foundation often collapses. Under section 365 of the Bankruptcy Code, a debtor may reject an executory contract, with the law treating that rejection as a prepetition breach and relegating the counterparty’s claim to general unsecured …

Infimum Dimension Nash Embeddings For 2d Projective Shape Analysis, Robert L. Paige, Vic Patrangenaru

Mathematics and Statistics Faculty Research & Creative Works

Vector embeddings make complicated data extracted from networks, words and images, more amendable to data science applications. At the present time, the Veronese-Whitney (VW) matrix embedding of the real projective space is the state of the art for making inference about digital images from an uncalibrated camera, such as a cell phone or security camera. In this work we consider vector embeddings for the projective shape data and in particular determine the minimum dimension isometric (distance-preserving or Nash) vector embedding for a projective space. We determine such an embedding for the projective plane in closed-form. From this embedding we determine …

A Fully Discrete Semi-Implicit Numerical Scheme And Its Optimal Error Estimates For Cahn-Hilliard-Mhd Model With Variable Density, Dongmei Duan, Fuzheng Gao, Xiaoming He, Yanping Lin

Mathematics and Statistics Faculty Research & Creative Works

This paper proposes and analyzes a fully discrete semi-implicit unconditionally energy stable numerical scheme to solve the Cahn-Hilliard Magnetohydrodynamics (Cahn-Hilliard-MHD) model with variable density. The unconditional energy stability and optimal L² error estimates are established for the fully discrete scheme. Major challenges in error estimation arise from the variable density, the strong nonlinearities, and the multi-physics coupling of the model. Under the mathematical induction framework, the Ritz quasi-projection and the Stokes quasi-projection, proposed in [SIAM J. Numer. Anal., 61(3):1218-1245, 2023], are utilized to avoid the gradient terms of the projection errors. The H⁻¹ superconvergence error estimates of Ritz …

Insurance And Chapter 11 Bankruptcy: Is The Insurance Neutrality Doctrine Dead?, Mikaela Deleon

Emory Bankruptcy Developments Journal

Insurers have traditionally been denied “party in interest” status under the Bankruptcy Code due to the longstanding insurance neutrality doctrine. The insurance neutrality doctrine prevents insurers from challenging a chapter 11 bankruptcy plan as a section 1109(b) “party in interest” if the plan does not increase the insurance company’s liability from pre-bankruptcy levels. If none of their rights or obligations were impacted by the plan, insurance companies were previously left without a means to challenge a proposed reorganization plan. As a result, insurance companies providing liability insurance to corporations stricken with mass tort lawsuits ran the risk of becoming the …

Asbestos 2.0: A Looming Disaster At The Intersection Of Pfas Litigation And The Texas Two-Step––Even After Purdue Pharma, Tyler Sheridan

Emory Bankruptcy Developments Journal

Companies that have manufactured, processed, or sold per- and polyfluoroalkyl substances (“PFAS”), also known as “forever chemicals,” face mounting financial pressure as the number of claims against them skyrocket. With billions of dollars already allocated to settlements and new lawsuits continuously filed, liable corporations may utilize the Texas Two-Step to minimize financial risk. The maneuver would enable solvent companies to isolate PFAS liability and discard it into bankruptcy, potentially delaying and capping payouts for claimants in the process. Third-party releases have survived Purdue, leaving the forum’s ability to permanently resolve mass tort liability intact. Moreover, escalating litigation may prompt …

Made On Mars: Design And Manufacturing Of Structural Polymer-Regolith Composites, Pailey M. Vitale

Williams Honors College, Honors Research Projects

Human exploration of Mars is constrained by harsh environmental conditions and the prohibitive cost of transporting materials from Earth. Long-term sustainability requires the local production of mechanical and structural components using resources available on Mars, thereby minimizing payload mass. This project investigates polymer–regolith composites derived from atmospheric CO₂ and mineral-rich regolith as a pathway toward in-situ manufacturing. These composites, when compatible with additive manufacturing, could replace imported plastics, enable on-demand fabrication, and support closed-loop recycling systems. The objective is to design and evaluate polymer–regolith composites that maintain mechanical integrity and environmental resistance under Martian conditions, including extreme temperature swings, radiation …

Microscopic Insights On Shear Rheology Of Polyampholyte Ionomers Via Molecular Simulations, Kyle Vonscio

Williams Honors College, Honors Research Projects

Ionomers are polymers that contain a small fraction of charged groups. The ionic attraction of charged groups allows ionomers to act similarly to crosslinked polymers. Depending on the strength of electrostatic interactions and structure of the ionomers, different dynamics and rheological responses can be observed. With moderate attraction between ions, these noncovalent crosslinks can be broken when heated, allowing ionomers to flow and show the strength of a crosslinked network at low temperatures. Nonequilibrium molecular dynamics (NEMD) simulations will be performed under shear in the xy-plane and the macroscopic rheology and conformation of the polyampholyte ionomer will be determined. The …

Women's Work And Wealth: Measuring The Impact Of Incremental Liberations, 1850-1870, Hannah Kelly

Williams Honors College, Honors Research Projects

Using a two-way fixed effects difference-in-difference model, this project analyzes data from the IPUMS Full Count census for 1850, 1860, and 1870 at a state level for 48 states. Four models assess the impact of property laws on women's real property holdings, labor force participation, household types, and real property values.

By quantifying the impact of various legal reforms on women's economic empowerment, this project fills a gap in the understanding of the intersection between law, society, and women's economic agency during a transformative period in pre-industrial American history. These impacts can implicate the effectiveness of legislative measures in advancing …
