While temporal behavioral patterns can be discerned to underlie real crowd work, prior studies have typically modeled worker performance under a simplified i.i.d. assumption. To better model such temporal worker behavior, we propose a time-series label prediction model for crowd work. This latent variable model captures and summarizes past worker behavior, enabling us to better predict the qual...

• Decision epochs are the beginning of every period. • Action space includes Keep (K), Release & Work (RW), Release & Idle (RI) and Idle (I) for each server. The 16 unique combinations of the two workers’ actions constitute the system’s action space. Action “Keep” requires the worker to continue working on the current job for one more period. Action “Release & Work” requires that the worker sto...

The author examines the history of U.S. labor and immigration policies, paying particular attention to the evolution of the temporary worker policy. Complications in the immigration reform process caused by efforts to admit more temporary workers are discussed. The position of the Reagan administration, Senate and House consideration of immigration and temporary worker bills, and the politica...

Worker Cooperatives and Democratic Governance A worker co-operative is a firm that is owned and managed by those who work in it. This paper provides a selective review of research in economics on worker cooperatives. It concentrates on the volatility of earnings and employment in the co-ops compared with conventional capitalist firms; on the long-term viability of co-ops; on the relative produc...

The participative standard with feedback condition was superior to the assigned difficult (140% of normal) standard with feedback condition in terms of worker productivity. The percentage increase in worker productivity with the participative standard and feedback condition was 46%, whereas the increase in the assigned difficult standard with feedback was 23%, compared to the control group (no ...

We analyze a model where a multinational firm can use a superior technology in a foreign subsidiary only after training a local worker. Technological spillovers from foreign direct investment arise when this worker is later hired by a local firm. Pecuniary spillovers arise when the foreign affiliate pays the trained worker a higher wage to prevent her from moving to a local competitor. We study...

The dissertation project presented here aims at identifying resources for work-integrated learning that are relevant to the current context of a knowledge worker. For finding suitable resources, methods of associative information retrieval are employed. The unified approach to search for useful material is based on a formal model of the domain the knowledge worker operates in and on statistical...
