indubitably, the efficacy of metalinguistic awareness in improving efl learners’ grammatical knowledge and writing quality has long been an area of great interest in applied linguistics brown (2001). accordingly, the main objective of the present study was to investigate the impact of planned and unplanned focus on form instruction on students’ ability to learn grammar and use it appropriately ...

If f = EW:-, a,,t” is a formal Laurent series with certain restrictions on the a,, then f = f-fof+ , where fcontains only negative powers of t, f+ contains only positive powers of t, and f. is independent of t. Applications include Lagrange’s formula for series reversion, the problem of counting lattice paths below a diagonal, and a theorem of Furstenberg that the diagonal of a rational power s...

The subunit of the Vicia graminea lectin with blood-group-N specificity was examined by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis and gel filtration in 6M-guanidinium chloride, and its molecular weights was found to be 25 000. The unique N-terminal sequence fof the first nine residues of the lectin confirmed that Vicia lectin consists of four identical chains non-covalently lin...

Contextualization of Geospatial Database Semantics Written by Administrator Thursday, 19 May 2011 07:40 Last Updated Friday, 04 October 2013 17:19 Human interactions with geographical information are contextualized by problem-solving activities which endow meaning to geospatial data and processing. However, existing spatial data models have not taken this aspect of semantics into account. This ...

We present ongoing research concerning a communicationbased approach to information modelling. The general goal of our research is to understand and support (contextualized) modelling dialogues rather than the models that result from these dialogues or the modelling languages in which the models are expressed. We take the point of view that information modelling dialogues are subject to the sam...

This paper describes ongoing work within the Light Water Reactor Sustainability pathway at Idaho National Laboratory (INL) to optimize security and cost of nuclear power plants. It introduces dynamic risk assessment tool developed INL, Event Modeling Risk Assessment using Linked Diagrams (EMRALD). EMRALD is leveraged posture a plant by integrating force-on-force (FOF) simulations operator mitig...

Background The aim of this paper is to explore how contextualization of a healthcare simulation scenarios impacts immersion, by using a novel objective instrument, the Immersion Score Rating Instrument. This instrument consists of 10 triggers that indicate reduced or enhanced immersion among participants in a simulation scenario. Triggers refer to events such as jumps in time or space (sign of ...

Human interactions with geographical information are contextualized by problemsolving activities which endow meaning to geospatial data and processing. However, existing spatial data models have not taken this aspect of semantics into account. This paper extends spatial data semantics to include not only the contents and schemas, but also the contexts of their use. We specify such a semantic mo...
