When Electrification Meets Reindustrialization: The First Eu Green Electric Vehicle Subsidies And The Wto Consistency, Mandy Meng Fang

Duke Journal of Comparative & International Law

The French Government recently reformed the "Ecological Bonus" scheme, which has generously supported its domestic consumers in purchasing electric vehicles ("EVs"), by introducing a new criterion based on the amount of carbon emitted in the vehicle's manufacturing. Starting in 2024, the scheme strictly sets the production carbon footprint ceiling at 14.75 tons of CO2, effectively denying the subsidy eligibility of more than one-third of EVs sold in France. Other European Union ("EU") Member States, including Italy, have considered taking similar policy actions. Criticized as the French version of the discriminatory United States Inflation Reduction Act, the new Ecological Bonus scheme …

Criminalization Of Homelessness: The Impact Of A Market-Oriented Approach, Gabriella M. Chioffi Jun 2025

Criminalization Of Homelessness: The Impact Of A Market-Oriented Approach, Gabriella M. Chioffi

Duke Journal of Comparative & International Law

Since the fourteenth century, countries have sought to criminalize unhoused individuals by labeling them as "vagrants." Currently, the United States and other countries continue to criminalize acts of sleeping rough, begging, loitering and other vagrancy-type activities that disproportionately target unhoused persons. Despite going through a period of decriminalization in the 1960s and 1970s, these punitive measures were largely reinstated by the 1990s. In the most extreme case, vagrancy criminalization was entrenched in a state's constitution. This Note contends that the reversion to punitive measures is triggered by a country's transition to a market-oriented approach that privatizes housing development and de-emphasizes …

Investigating Momentary Body Image Disturbance, Affect, And Disordered Eating Among College Students, Allison T. Cunning Jun 2025

Investigating Momentary Body Image Disturbance, Affect, And Disordered Eating Among College Students, Allison T. Cunning

USF Tampa Graduate Theses and Dissertations

Despite evidence that eating disorders are associated with elevated mortality rates, increased risk of suicide, and societal and financial burden, treatment outcomes for individuals with eating disorders remain poor. Body image disturbance has emerged as a robust risk factor for the development and maintenance of disordered eating (e.g., overeating, binge eating, purging, restriction) and theoretical and clinical perspectives most commonly operationalize body image disturbance as a trait construct. However, empirical evidence suggests body dissatisfaction may fluctuate, and these fluctuations may play an important role in the relationship between risk factors and disordered eating. The current study employed ecological momentary assessment …

The Improvement Regime: Public Trusts, Real Estates, And India’S Urban Futurities, Anwesha Ghosh Jun 2025

The Improvement Regime: Public Trusts, Real Estates, And India’S Urban Futurities, Anwesha Ghosh

Articles

Over the last two decades, since scholarly writing on India witnessed an “urban turn,” numerous historians have analyzed the role of the improvement trust in the redevelopment of Indian cities in the twentieth century, most specifically those of Bombay, Calcutta, and Delhi. This paper revisits and reassesses some of their key arguments to suggest that rather than studying the “failures” of the individual trusts to foster sanitary built environments, we should pay attention to the contingent workings of the city trusts that were constitutively designed for such failures. Using a comparative analysis of the Bombay and Calcutta improvement trusts, this …
