This paper describes a new efficient speech act type tagging system. This system covers the tasks of (1) segmenting a turn into the optimal number of speech act units (SA units), and (2) assigning a speech act type tag (SA tag) to each SA unit. Our method is based on a theoretically clear statistical model that integrates linguistic, acoustic and situational information. We report tagging experiments on Japanese and English dialogue corpora manually labeled with SA tags. We then discuss the performance difference between the two languages. We also report on some translation experiments on positive response expressions using SA tags. Click here to read more…
In 2008, Xstrata Zinc launched a project to investigate the best ways to cover waste rock facilities at Black Star Open Cut (BSOC) mine. We have committed $1 million to the project over five years. The first phase of the project will determine how much water enters waste rock facilities, using mathematical models and experiments on waste rock test plots. We constructed plots with cover of varying thickness and compaction, and measured the moisture levels within the plots using a series of sensors. Read more..

Study about Trends in Public Participation: Local Government Perspectives
Introduction: Enhanced public participation lies at the heart of the Labour government’s modernization agenda for British local government. As the white paper Modern Local Government: In Touch with the People states, ‘the Government wishes to see consultation and participation embedded into the culture of all councils and undertaken across a wide range of each council’s responsibilities’ (DETR 1998, para. 4.6).
Such bold statements suggest that the modernization programme is introducing fundamental change into local democratic practices: change which is addressed as much towards altering cultures and attitudes within local government as it is towards creating new opportunities for democratic participation. Yet the belief that local government should involve the public or ‘get closer to the community’ is hardly new. The history of British local government is littered with experiments in public participation and consultation (Gyford 1991; Burns et al. 1994; Stoker 1997). Keep reading…
Evaluating student achievement through performance assessments is not a new strategy. Good teachers have always judged and monitored their students’ progress through observations, experiments, written assignments, and research projects. What is new in the current reform effort is the systematic shift toward schoolwide performance assessments and away from multiple-choice tests for measuring instruction and accountability.
Proponents of performance assessments argue that assessment and instruction must form a seamless web that promotes teacher/student collaboration, active learning, critical thinking skills, and multidisciplinary understanding. Performance assessments, they reason, have a positive influence in the classroom. To refer this case study click here Performance Assessments Affect Teaching and Learning
