Although specifically directed toward the nation's K-12 Brown v. Board also opened wider the doors of postsecondary education for African Americans. The landmark decision has led to increased enrollment of African American students in predominantly White colleges and universities. Still, 50 years after the Supreme Court's ruling, African Americans are still proportionately underrepresented in these institutions, which are frequently unwelcoming and sometimes even hostile settings. Many...

Abstract To quantify and characterize the spatial distribution of clupeid fish schools, sonar data were collected during surveys off the coast of Namibia in 1994 (pilchard (Sardinops sagax), anchovy (Engraulis capensis), and round herring (Etrumeus whiteheadi)), off Angola in 1995 (sardinella (Sardinella sp.)) and in the Norwegian Sea in 1997 and 1998 (Norwegian spring-spawning herring (Clupea harengus L.)). The two-dimensional distances between clupeid schools were calculated in the order...

This can partially be ascribed to academics' strong views on academic freedom and autonomy. In this paper an admissible distinction between quality assurance and quality enhancement as two entries on a continuum is made. A plea is made that Southern African higher education institutions should invest in establishing self-reflective practices rather than a culture...

Mt Kilimanjaro, Africa's highest mountain (5895m), is a large, young (<1.6Ma) stratovolcano at the southern end of the East African Rift, in northern Tanzania. Consisting of three distinct volcanic centres, Shira, Mawenzi and Kibo, Shira contains the highest proportion of mafic rocks. Shira samples are strongly silica under-saturated rocks, ranging from picro-basalt, to nephelinite and hawaiite (Mg numbers (Mg #) ranging from 77.2-35.5). Phenocrysts constitute up to 55% of some samples, and...

This paper presents a bio-economic model of Andit Tid, a severely degraded crop-livestock farming system with high population density and good market access in the highlands of Ethiopia. Land degradation, population growth, stagnant technology, and drought threaten food security in the area. Drought or weather risk appears to have increased in recent years. The bio-economic model is used to analyse the combined effects of land degradation, population growth, market imperfections and...
