Stocks And Shocks: Assessing The Relative Roles Of Public And Private Inventories In Buffering Rice Price Volatility In The Philippines, Bernhard Dalheimer, Kenneth Foster, Gerald E. Shively, Valerien O. Pede, Dela-Dem Doe Fiankor, Jacob Ricker-Gilbert, Pratibha Bist

Department of Agricultural Economics Faculty Publications

Public stockholding of food is politically contentious and economically challenging. Although private stocks are generally understood to be more efficient than public stocks at providing a reliable buffer against production shortfalls, private stocks often fail to stabilize prices during extreme food market shocks. Moreover, maintaining large public stock programs in which the government acts as the buyer or seller of last resort, can be very costly. This paper analyzes the recent historical success of public and private rice stocks in stabilizing domestic rice prices in the Philippines, the world’s largest net importer of rice. Relying on competitive storage theory and …

From Text To Action: Seeing Software Commands Through Ar Gestures, Shengyang Luo, Yingjie Chen

Purdue Polytechnic Graduate Student Poster Symposium

Learning feature-rich software often requires mastering complex keyboard-mouse combinations, yet text-based tutorials struggle to convey how these interactions should physically happen. Many learners pause, re-read, and search online, still unsure how to execute commands until a TA or peer demonstrates the gesture in person. We explore an AR-based tutorial approach that displays 3D hand and input animations directly within the learner’s view as they operate the software. By turning written instructions into embodied, real-time motion guidance, this system aims to make advanced software interactions more intuitive and accessible, reducing confusion and supporting confident skill development.
