Post-stroke dysphagia, a potentially fatal complication, affects an estimated 23-50% of all stroke survivors. It is associated with a seven fold increase in the risk for aspiration pneumonia. Aspiration pneumonia increases the catabolic demands of the body and in the settings of impaired swallowing leads to a vicious cycle of malnutrition, dehydration, and further infections (Shaker & Geenen, 2011). Dysphagia affects a significant number of patients with hemispheric stroke which is the main subtype of ischemic stroke in the general population (Kumar et al., 2011). The functions of swallowing are subserved by a vast brain network. The inferior peri-rolandic sensorimotor ...

Question #1

The coefficient of determination (R-squared) shows the proportion of variance in the dependent variable, which is explained by the independent variable. Let’s say, the independent variable is the amount of money invested by a population of investors and the dependent variable is their profits received. Assume, the R-squared between the variables is 0.8567. This means that approximately 85.67% of the variance of profit received is explained by the amount of invested money.

Question #2

This phrase means that if the coefficient of correlation shows a strong relationship between the variables, it not always mean that there is a real causal ...

1. Misconceptions Money generation remains central to economic activity. The process of how money is generated / created and destroyed is not, in fact, readily understood and is subject to numerous misconceptions. If anything, main conceptions about money creation and destroy assumes a linear conceptualization mode. Typically, money is widely – but mistakenly – believed to be created and destroyed by a direct relationship by which an owner places money deposits in a financial institution which, sooner or later, lends money to borrowers and hence creates more money. In modern era, particularly in a global financial system in which financial transactions ...

Forecasting methods in health services

Forecasting is a mathematical prediction process that uses the data from the past records to predict the future outcomes. In the case of the health services, it uses the number of patients visiting a given health facility for a given period of time, like, say, for a whole year or a month in order to predict the estimated number of expected patients in the following year. This helps the health facility managers to make a prior plan of financial and material expenditure for the year or month to come. In addition, forecasting helps to monitor the operational efforts in ...

Introduction

How materials behave is dependent on various factors, some of which include their mechanical properties. When the material experiences various loading conditions, its behavior reflects its mechanical conditions as well as the effect of the loading conditions. When a material experiences various loading conditions, the material experiences either shear stress, tensile strength, or compressive strength. The tensile properties of a material relate to its ability support any axial loads to which it is subjected without rapturing (Department of Engineering. 2007). When a material is subjected to tensile stress, the deformation that occurs is in the form of elongation or ...
