Intelligent user assistance systems face challenges of incomplete, uncertain and multiple modality sensory observations, user’s changing internal state, and constraints in making decisions. We introduce a probabilistic framework to dynamically model user’s affective state with various visual cues in such systems. A systematic mechanism performs purposive and sufficing information integration to...

Synthetic routes to 5'-azidoribonucleosides are reported for adenosine, cytidine, guanosine, and uridine, resulting in a widely applicable one-pot methodology for the synthesis of these and related compounds. The target compounds are appropriate as precursors in a variety of purposive syntheses, as the synthetic and therapeutic relevance of azido- and amino-modified nucleosides is expansive. Fu...

The objectives of this research were to study FB implementation and attitudes in developing English writing skills of Thai students studying in the first year students program in EIC academic year 1/2014 at RMUTI, Surin Campus. The Purposive sampling was designed for data collecting. The instruments for this research were questionnaires and in-depth questions. The data analysis was analyzed by ...

The Study of School Turnaround examines the improvement process in a purposive sample of 35 case study schools receiving federal funds through the School Improvement Grants (SIG) program over a three-year period (2010-11 to 2012-13 school years). This evaluation brief focuses on 11 of these SIG schools with high proportions of English Language Learner (ELL) students (a median of 45 percent ELLs...

What is functionalism? Both Silverstein (1987) and Nichols (1984) have analyzed in detail the variety of ways functionalism has been used by linguists. Silverstein made a division into four types of functions, referential and pragmatic: (a) `sense-structure', (b) the `abstract, "sentence"-internal distribution of forms,' (c) the `use of signal forms for purposive, intentional social effect' (d)...

In this paper ongoing work on an approach for planning sensing actions and controlling intelligent, purposive robotic systems is presented. The method uses Bayesian Decision Analysis (BDA) for deciding what sensing actions should be performed. This ooers a probabilistic framework that provides a more dynamic and modular behaviour than traditional rule based planners. Experiments show that the B...

Roger E. Kahn and Michael J. Swain Department of Computer Science University of Chicago 1100 East 58th Street Chicago, IL 60637 Abstract In this paper we present Perseus, a purposive visual system used by our robot, CHIP, to locate objects being pointed at by people. Perseus uses knowledge about the task and environment at all levels of processing to more accurately and e ciently perform visual...

Background: There is limited empirical research on the role of individuals’ career orientations, digital-era world work awareness and agility mindset in purposive exploration. Objectives: The objective this study was to assess extent which orientations contribute a mindset. Method: cross-sectional quantitative survey involved sample 486 adult learners (65% women; 35% men; 85% black learners; 15...
