In brain magnetic resonance (MR) images, image segmentation and 3D visualization are very useful tools for the diagnosis of abnormalities. Segmentation of white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF) is the basic process for 3D visualization of brain MR images. Of the many algorithms, the fuzzy c-means (FCM) technique has been widely used for segmentation of brain MR image...

The soft budget constraint hypothesis of Kornai (1980) offers an attractive explanation of overmanning in public enterprises. Sometimes overlooked in the literature is the fact that governments, especially in transition economies, often use state-owned enterprises (SOEs) to pursue non-financial objectives and to finance the resulting social burdens with subsidies and policy loans.

Virtually everyone is in favour of ̳social justice‘ but their interpretations of the term vary widely (there are many different varieties of apple!). We ...

In this article, I explore the South African 2003 National School Health Policy (NSHP) and the revised 2012 Integrated School Health Policy (ISHP). I examine whether the shortcomings in the development, content and implementation of the 2003 NSHP, and the context in which it was implemented, have been addressed adequately in the 2012 ISHP. The shortcomings include poorly structured relationship...

In these circumstances health policy tends to focus on ways of...
