cash flow forecasting is an indispensable tool for construction companies, and is essential for the survivalof any contractor at all stages of the work. the time available for a detailed pre-tender cash flow forecast is oftenlimited. therefore, contractors require simpler and quicker techniques which would enable them to forecast cash flowwith reasonable accuracy. forecasting s-curves in constr...

INTRODUCTION Endodontic claims are the most frequently filed malpractice claims in dentistry. The aim of this study was to categorize and review errors and complications related to endodontic procedures that resulted in legal actions against the treating practitioner. METHODS All dental malpractice complaints reported to the Medical Consultants International Company (MCI) in Israel between th...

This paper investigates the influence of mean areal rainfall estimation errors on a specific case study: the use of lumped conceptual rainfall-runoff models to simulate the flood hydrographs of three small to medium-sized catchments of the upper Loire river. This area (3200 km2) is densely covered by an operational network of stream and rain gauges. It is frequently exposed to flash floods and ...

Testing the out-of-sample forecasting superiority of one model over another requires an a priori partitioning of the data into a model specification /estimation (‘training’) period and a model comparison/evaluation (‘out-of-sample’ or ‘validation’) period. How large a validation period is necessary for a given mean square forecasting error (MSFE) improvement to be statistically significant at t...

This paper examines the relationship of analysts’ coverage, forecasting errors and earnings management. It corroborates the role of analysts as gatekeepers by finding that analysts enhance transparency and reduce the scope of earnings management. To identify analysts’ coverage we used the I/B/E/S, from where we also obtained information on the consensus projections of analysts for listed Brazil...

this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

In this study, the weather forecasting model of the National Centre for Medium Range Weather Forecasting (NCMRWF) is used for examining the characteristics of round-off-errors on three different computer architectures e PARAM 10K, SUNFIRE 6800 and Dec Alpha for several meteorological parameters such as precipitation, temperature at the surface and mid-atmosphere, and upper and lower level winds...
