Public Land Revisited: Municipalization And Privatization In Newark And New York City, Samuel Stein, Oksana Mironova Dec 2018

Public Land Revisited: Municipalization And Privatization In Newark And New York City, Samuel Stein, Oksana Mironova

Publications and Research

Public land plays a central role in contemporary urban planning struggles. Using a comparative case study approach focused on the north-eastern US cities of Newark and New York City, we uncover patterns of land acquisition and dispossession that fit five broad and often overlapping periods in planning history: City Beautiful, metropolitan reorganization, deindustrialization, and devaluation, followed by hyper-commodification in New York City and redevelopment amidst disinvestment in Newark. Through this periodization, we find that accumulation and alienation of urban public land has largely taken place through two modes of municipalization (targeted and reactive) and two modes of privatization (community-led and …

Accounting For The Environmental Impacts Associated With Residual Products In A Comparative Life Cycle Assessment Of Systems With Multiple Products, Yasuhiro Fukushima, Satoshi Ohara

Journal of Environmental Science and Sustainable Development

In many production systems, multiple products are interactively produced. Therefore, an innovative technology that leads to changes in parts of such systems may influence both the unit environmental impacts associated with the products, and the productivity of multiple products. To compare alternative technologies on a common basis, we often account for the avoided or supplemented emissions associated with the residual (i.e. surplus and supplemented) products produced from within the considered system boundary. In this study, using an example of an innovative technology envisioned for use in sugar mills, we first demonstrate how comparisons can be made when the systems vary …

Armenia And Azerbaijan's Struggle With Occupation In Nagorno-Karabakh, Carolyn Morway Dec 2018

Armenia And Azerbaijan's Struggle With Occupation In Nagorno-Karabakh, Carolyn Morway

Brooklyn Journal of International Law

The corrupt occupation of Nagorno-Karabakh and its surrounding areas has resulted in displaced civilians, chaotic military violence, poor judicial law-making, and hostile international relations. Analyzing the international law of occupation’s purposes and its humanitarian requirements illustrates that there is a need for change. Set against the backdrop of Nagorno-Karabakh’s precarious situation, the international community should take this opportunity to reformulate the international law of occupation with sovereignty and humanitarian principles guiding the change. The effort could prevent another such “frozen conflict.”
