Despite the growing number of studies highlighting the complex process of acquiring second language (L2) word recognition skills, comparatively little research has examined the relationship between word recognition and passage-level reading ability in L2 learners; further, the existing results are inconclusive. This study aims to help fill the gap. Three word recognition subcomponents (decoding...
A survey of the literature was made to determine the skills involved in reading comprehension that are deemed most important by authorities. Multiple-choice test items were constructed to measure each of nine skills thus identified as basic. The inrcrcorrclarions of the ninc skill scores were factored. each skill being weighted in the initial matrix roughly in proportion to its importance in re...
This paper studies the issue of tax evasion in the context of the underground economy. A dynamic general equilibrium model is built where individual households and entrepreneurs decide rationally whether to go underground and under-report their earnings. These behaviors affect tax revenues, which are used to finance productive public services. This model is applied to the Czech Republic, becaus...
It has been observed that in the urban center of Shanghai, land subsidence has accelerated, and the groundwater level has continued to drop even though the net withdrawn volume (NWV) of groundwater has remained unchanged since 1980. An analysis of monitoring data shows that drawdown of the groundwater level is one of the factors that have influenced land subsidence since 1980. The NWV of ground...
A theoretical model for carbon dioxide (CO2) migration in tilted aquifers with groundwater flow is presented to evaluate the injection of CO2 into a geological formation. Capillary force in the flow of two immiscible fluids in a porous medium creates a saturation transition zone, where the saturation changes gradually. A vertical equilibrium assumption is employed to solve for the capillary pre...
underground economy affects important indexes such as formal gdp, unemployment, consumption, production and etc. therefore it is necessary to identify elements and factors which affect underground economy to restrict it. surveys and studies indicate the size of iran’s underground economy is high and taxes, quantity and quality of regulations and performance of formal economy are the important f...
The foundation framework for underground spatial data aims to establish the platform for the underground spatial data sharing and integrating. The reasons lie in that: a) the long-term development of city construction has accumulated abundant underground spatial data and information; b) the development and utilization of city underground space demands for clear, detailed and visualized comprehe...
The goal of reading is understanding. In order to understand print, a child must be able to decode the words on the page and to extract meaning. A large body of research focuses on how children learn to decode text and how best to foster children’s decoding skills. In contrast, we know much less about the process of reading comprehension in children. In this booklet we first consider what is re...
preciated only with the assistance of pencil and paper. On pedagogic grounds, this may be a blessing in disguise, even if it slows the reading pace. In conclusion, it should be stressed that this book is not an attempt to present an uncritical, comprehensive overview of the state of affairs in a special area of biochemistry. It is highly selective and clearly centered on the author's own contri...
COVERAGE: Lecture Notes 6 and 7; Problem Sets 3 and 4; Rowan-Robinson, Chapters 4 and 5; Weinberg, Chapters 4 and 5. One of the problems on the quiz will be taken verbatim (or at least almost verbatim) from either the homework assignments, or from the starred problems from this set of Review Problems. The starred problems are the ones that I recommend that you review most carefully: Problems 1,...
