The notion of choice has been characterised as one of the regulating agents of intrinsicmotivation. A study being carried out at the Université H. Poincaré is investigating the effect ofchoice on cognitive and affective engagement during listening tasks. The study compares twogroups of English language learners specialising in other disciplines. The aim of the study is toattempt...

The purpose of applying the high-energy γ-ionizing radiation with doses up to 100 kGy was to enable controllable change of mechanical properties of high impact polystyrene (PS-HI) and, at the same time, to investigate the possibility of using reprocessed irradiated polymeric material. Dielectric relaxation of radiation modifi ed high impact polystyrene (PS-HI) has been investigated below the po...

Nitrogen supplied by N2 fixation to soybean [Glycine max (L.) Merr.] may not be sufficient to maximize yield. Field studies were conducted in 2002, 2003, and 2004 on Sharkey clay soil (very-fine, smectitic, thermic Chromic Epiaquert) at Stoneville, MS (33 269 N lat). The objective was to determine the effect of high rates of N applied as a replacement for N2 fixation in nonirrigated and irrigat...

nature) can usually be explained by either increased pleural fluid formation or decreased pleural fluid absorption, or both. Pleural effusions caused by an increase in pleural fluid formation can be further subdivided into elevation in hydrostatic pressure (e.g., congestive heart failure), decreased colloid osmotic pressure (e.g., cirrhosis, nephrotic syndrome), increased capillary permeability...

In the first paragraph of page 627, under section ‘Diversity measures and functional composition’, sentence "Positive or negative SES.MPD/MFD values indicate phylogenetic/functional clustering overdispersion species in fragment, respectively (Webb et al. 2002).” was published incorrectly. The correct should read

OBJECTIVE To summarize national trends in the incidence of congenital syphilis (CS) and associated mortality. METHODS We analyzed CS surveillance data reported to the Centers for Disease Control and Prevention by 50 states and the District of Columbia from 1992-1998. RESULTS From 1992-1998, 942 deaths, including 760 stillbirths, were reported among 14 627 cases of CS, yielding a case fatali...

The teaching of Languages for Specific Purposes (LSP) in the second half of the twentieth centuryhas been greatly influenced both by the communicative approach and by developments inresearch in discourse analysis, particularly with reference to genre. The integration of researchin corpus linguistics in the language-learning environment has been a more recent phenomenon,with publ...

Introduction Hydrogeologic investigations are often hampered by insufficient information about the site-specific hydrostratigraphic features that control ground water flow and solute transport. Field and modeling studies in a wide variety of geologic settings have shown the importance of a detailed description of aquifer heterogeneity for applications ranging from prediction of contaminant tran...
