This paper provides a survey of work on the link between education and economic growth. It shows that data from the early 20th century are coherent with conclusions about education and economic growth derived from the much more recent past. It also presents an analysis of the role of education in facilitating the use of best-practice technology. It is to be published in the International Handbo...

As student numbers in the UK’s higher education sector have expanded substantially during the last 15 years, it has become increasingly important for government to understand the structure of costs in higher education, thus allowing it to evaluate the potential for expansion and associated cost implications. This study applies Data Envelopment Analysis (DEA) to higher education institutions (HE...

Many of the chronic infectious disease problems in the goat herd are lifelong infections from exposure of kids near the time of birth. Infectious disease control programs start with planning kid-rearing strategies to minimize infection of the neonate. Pasteurized rearing strategies are commonly used to prevent mycoplasmosis and caprine arthritis-encephalitis virus (CAEV), however pasteurized re...

This study applies the environmental Kuznets curve to test the relationship between the regional economic growth and the different types of agricultural nonpoint source pollution loads in the Ningxia Yellow River irrigation area by using the Johnes export coefficient method. Results show that the pollution load generated by crop cultivation and livestock-breeding industries in the Ningxia Yello...

ABSTRACT A model of international tax competition is developed in which taxes are raised in order to finance education which in turn raises income. It is shown that, in contrast to results from the tax competition lite...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
