In order to calculate confidence intervals and hypothesis tests, it is assumed that the errors are independent and normally distributed with mean zero and variance 2 σ . Given a sample of N observations on X and Y, the method of least squares estimates β0 and β1 as well as various other quantities that describe the precision of the estimates and the goodness-of-fit of the straight line to the d...

Map Generalization is one of the hotspot issues in GIS. It is the most imperative field for intelligence in GIS. The uncertainty and data quality of map generalization should be attached importance to in map generalization. The conventional methods of process of line generalization in map generalization are be introduced in this paper, and analysis decline in the quality of integrated because o...

The relationship between physical activity and health-related physical fitness was evaluated in 282 Taiwanese adolescents 12-14 years of age. The subjects were randomly selected from the 7th, 8th and 9th grades in two junior high schools in Taiwan. Physical activity was estimated as total daily energy expenditure and energy expenditure in moderate-to-vigorous physical activity from 24-hour acti...

Background and Aim: This study assessed the salivary calcium level, salivary flow rate, and dental problems of patients with Sjogren’s syndrome. Materials and Methods: This case-control study was conducted on 30 patients with Sjogren’s syndrome and 30 healthy controls. The salivary flow rate, salivary calcium level, and the decayed, missing, and filled surfaces (DMFS) index were recorded. ...

Two studies investigated the effects of prosody, context and thematic fit on off-line and on-line processing of sentences like John greeted Paul yesterday and Ben today. Such sentences are ambiguous between the so-called 'nongapping' reading, where John greeted Ben, and the highly unpreferred 'gapping' reading, where Ben greeted Paul. Participants listen to dialogues and give a speeded response...

We studied the moderating effects of cardiorespiratory fitness and physical activity on heart rate and blood pressure responses to psychophysiological stressors and the carotid-cardiac baroreflex in young normotensive women with a parental history of hypertension (n = 31). Testing occurred during the follicular menstrual phase. Subjects were divided into high versus moderate (46.6 +/- 6.5 versu...

International evidence show that screening for colorectal cancer is cost-effective; however, in Argentina is unknown. OBJECTIVE The study shows the results of a cost-effectiveness evaluation based on two alternative mechanisms: annual faecal immunochemical testing (FIT), and colonoscopy every ten years in Argentina. METHODS The study develops a Mar- kov model in ten stages, based on informa...

Through an analysis of the relationship between human resource management (HRM) systems and strategy types, predictions are made about a simultaneous horizontal and vertical fit. In a conceptual model for strategic HRM the key argument is, that the fit between firm strategy and HRM strategy is determined by (matching hypothesis) task characteristics of the strategy type and internally, consiste...
