the formulation of global health policy is political; and all institutions operating in the global health landscape are political. this is because policies and institutions inevitably represent certain values, reflect particular ideologies, and preferentially serve some interests over others. this may be expressed explicitly and consciously; or implicitly and unconsciously. but it’s important t...

Understanding the spatial patterns of urban land use at both the macro and the micro levels is a central issue in global change studies. Due to the nonlinear features associated with land use spatial patterns, it is currently necessary to provide some distinct analysis methods to analyze them across a range of remote sensing imagery resolutions. The objective of our study is to quantify urban l...

We define the presented dimensions for modules and rings to measure how far away a module is from having an infinite finite presentation and develop ways to compute the projective dimension of a module with a finite presented dimension and the right global dimension of a ring. We also make a comparison of the right global dimension, the weak global dimension, and the presented dimension and div...
