BACKGROUND Recruiting an adequate number of participants into medical research studies is challenging for many researchers. Over the past 10 years, the use of social media websites has increased in the general population. Consequently, social media websites are a new, powerful method for recruiting participants into such studies. OBJECTIVE The objective was to answer the following questions: ...
abstract this mixed method study examines whether there is any relationship among the variables of the study (job satisfaction, social capital and motivation). the researcher considered job satisfaction and social capital as independent variables; motivation is the dependent variable of the study. the researcher applied a questionnaire to assess each variable. to measure efl teachers’ job sati...
The objective of this study is to estimate the mean annual social cost per adult person and the total social cost of rheumatoid arthritis (RA) in Italy.

The review results were merged with data of institutional sources for estimating - following the ...
The cost of equity plays a crucial role in financing and investment decisions. Investors tend to invest in stocks of companies which their cost of equity is low, therefore, factors affecting the cost of equity are important from both theoretical and practical point of view. Corporate social responsibility activities can reduce equity costs. But this can be achieved within the mechanism of prote...

In other words, we investigate the role of structural components and their effects on the size of the welfare cost in Iran's industry sector. We have used the Leibenstein's model to calculate the deadweight loss and then the pan...
Proof: (by induction). We want to show that one SAP doesn’t introduce negative cycles in Gf . Initially there are no negative cost cycles. Feasible prices can be computed by using shortest path distances from s. After finding the shortest s-t path, it has reduced cost 0. Every arc on the path has reduced length 0. This demonstrates that the triangle inequality property is tight on shortest path...
