AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
International Journal of Urban and Regional Research, EarlyView.Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

THE ANALOG CITY: Maintaining Everyday Life Through Repair and Jugaad
International Journal of Urban and Regional Research, EarlyView.Abstract Urban scholarship consistently discusses improvisation and heterogeneity as central to urban life in the global South. In this article, I bring together scholarship on urban improvisation and the digital world of smart cities to understand the city as analog.

Secure Mobile-Phone Based Visible Light Communications With Different Noise-Ratio Light-Panel
IEEE Photonics Journal, 2018 We propose and demonstrate a visible light communication (VLC) system using a light-panel and a mobile-phone camera. We also propose the rolling-shutter-effect (RSE) pattern synchronization and demodulation algorithms. By using our developed mobile-phone

Sanctions, National Security, and Free Speech
Global Policy, EarlyView.ABSTRACT A fundamental, but largely overlooked, aspect of the New Washington Consensus is the use of national security arguments to restrict speech and punish disfavored speakers. Although the United States has a longer history of using sanctions to restrict speech in the terrorism context, it has recently applied sanctions to restrict political speech,

Color-Shift Keying for Optical Camera Communication Using a Rolling Shutter Mode
IEEE Photonics Journal, 2019 An optical camera communication (OCC) is a special type of a visible light communication that uses a complementary metal-oxide semiconductor as a receiver. However, it is difficult to apply a high-order modulation scheme to such communications because of
