چکیده
Governments and international donors have long financed tractors for small farmers in the backward rural areas as a means of increasing their standard of living and promoting development. Past experiences in the provision of collective tractors to these areas showed negative results in that the tractors ended up benefiting mostly better-off farmers or were left in the countryside without maintenance. This study examines several cases of collective tractors managed successfully by rural associations and cooperatives in the semiarid area of the state of Ceari in Northeastern Brazil. What conditions have been necessary for this good performance? In answering this question, I review the past experience of federal and state programs providing these machines to farmers, and the current approach under which farmers have to contribute with a percentage of the total cost of the tractor. As a result of this direct stake in the good functioning of the tractor, I argue that these organizations have been able to adequately manage their tractors by developing a clear set of rules that (i) minimized the conflicts for the use of the machine and (ii) recovered their operation and maintenance costs. The arrangements these groups have devised included more equitable assignments in the order of tractor use and criteria for defining it on the basis of the rainfalls. Revenue maximization and cost rationalization are also part of the arrangements that the communities have learned and adopted over time. I conclude with some remarks on how planners and policy makers should continue funding tractors to these kind of organizations. Thesis Supervisor: Judith Tendler Title: Professor of Political Economy

A Platform for Building Mobile Virtual Humans
We describe an authoring framework for developing virtual humans on mobile applications. The framework abstracts many elements needed for virtual human generation and interaction, such as the rapid development of nonverbal behavior, lip syncing to speech, dialogue management, access to speech transcription services, and access to mobile sensors such as the microphone, gyroscope and location com...

A virtual agent that guides users through mindfulness meditation sessions is described. The agent uses input from a respiration sensor to both respond to user breathing rate and use deep breaths as a continuation and acknowledgment signal. A pilot evaluation study comparing the agent to a selfhelp video indicates that users are very receptive to the virtual meditation coach, and that it is more...
متن کاملLOITER-TB: Thought Bubbles that Give Feedback on Virtual Agents' Experiences
We demonstrate loiter-tb, a prototype of a serious game meant to improve the social awareness of police students. Central to its design is the provision of feedback through thought bubbles of virtual characters with which players interact. Our initial experiments provide weak support for our hypothesis that this form of feedback leads to gains in police students’ understanding of social interac...
متن کاملOpponent Modeling for Virtual Human Negotiators
Negotiation is a challenging domain for virtual human research. One aspect of this problem, known as opponent modeling, is discovering what the other party wants from the negotiation. Research in automated negotiation has yielded a number opponent modeling techniques but we show that these methods do not easily transfer to human-agent settings. We propose a more effective heuristic for inferrin...
