Understanding the conditions underlying the proliferation of infectious diseases is crucial for mitigating future outbreaks. Since its arrival in North America in 1999, West Nile virus (WNV) has led to population-wide declines of bird species, morbidity and mortality of humans, and expenditures of millions of dollars on treatment and control. To understand the environmental conditions that best...

The main aim of this study is to investigate the economic determinants of the demand for higher education at public universities in Jordan during the period 1990-2010. A co-integration analysis with four explanatory variables is used. Unit root tests have been employed to test the integration order of variables. For the purpose of supporting the results, the dynamic relationships among the vari...

Food insecurity and illiteracy involve more than 800 million people today. In the proposed paper, I argue that education is a fundamental factor in achieving food security for rural populations in developing countries. I base my arguments on the Human Development Approach, according to which, education is both intrinsically and instrumentally relevant for education. In this paper I focus on the...

P cross-cultural variation in economic experiments was unexplained by individuallevel variables such as wealth, income, gender, and education, even though variation across societies was explained by market integration and potential returns to cooperation (Henrich et al. 2001; Henrich et al. 2004). However, the previous data contained relatively poor measures of individual income, wealth, and ma...

This paper suggests that consistently referring to variables as placeholders is an effective countermeasure for addressing a number of the difficulties students’ encounter in learning mathematics. The suggestion is supported by examples discussing ways in which variables are used to express unknown quantities, define functions and express other universal statements, and serve as generic element...
