A recent report has shown that the relationship, at the latent variable level, between fluid ability and working memory capacity is affected by the time allowed for completing problems requiring the former (Chuderski, 2013): the greater the time, the lower the relationship. The underlying argument is that unti-med administration of fluid ability problems(More)
Extracting information or discovering knowledge from wireless or mobile grids is becoming increasingly important issues. Most researches in grid environment only consider data mining time. Other constraints, such as energy consumption and immediate bandwidth that are more important in the mobile computing will physically affect the performance and system(More)
In this paper, we propose an agent and ontology based information retrieval architecture for mobile grid, named AIR, to discover and extract from mobile grid environment in a flexible, transparent, and easy way. Based on the AIR, users can submit a flat-text based request to mobile grid for discovering information or knowledge. The request will be(More)
In this paper, we, based on mobile agent technology, propose a Resource-Aware Knowledge Extraction aRchitecture on mobile grid, named RAKER. RAKER can dynamically determine the processing and policy for achieving high-performance and high availability of knowledge extracting based on our previous proposed Resource Estimation Model. On the RAKER, users can(More)
Computerized tasks allow a more fine-grained analysis of the strategy deployed in a task designed to map a specific ability than the usual assessment on the basis of only the level of performance. Manipulations expected to impair performance sometimes do not have that effect, probably because the level of performance alone can confound the assessment of the(More)
Convergent validity of two tests of conscientiousness. The absence of correspondence between objective measurement of behavior and measurement based on self-report along with generalized use of questionnaires as personality assessment instruments raises a problem with regard to the validity of assessment instruments in this area of study. The goal of this(More)
The development of assessment management system has been discussed for a long time. The motivation always focuses on the evaluation of learners' ability or on the difficulties of examination. The common examination content could be composed by text or simple figures, and the assistant functionalities could also be developed to meet the individual needs. But(More)
BACKGROUND Multistage adaptive testing has recently emerged as an alternative to the computerized adaptive test. The current study details a new multistage test to assess fluid intelligence. METHOD An item pool of progressive matrices with constructed response format was developed, and divided into six subtests. The subtests were applied to a sample of(More)
