Some Issues in the Economics of Tertiary Education

The failure of the tertiary education to respond to the manpower needs of a technologically changing environment has been the concern of most social scientists. The inabilities to deliver higher education to a wider base and the deterioration of academic standards have been plaguing the education sector. This article attempts to present some of the issues related to the government’s role in higher education, rates of return from human capital investments, loan markets for tertiary education, tuition fees and labor market policies.rate of return, education, human capital

Study of the Correlations Between the Highest Energy Cosmic Ray Showers and Gamma Ray Bursts

We examine the correlation between the arrival direction of ultra high energy cosmic ray showers and gamma ray bursts in the third BATSE catalog. We find no correlation between the two data sets. We also find no correlations between a pre-BATSE burst catalog and the Haverah Park Ultra High Energy shower set that cover approximately the same period of time.Comment: 1 uuencoded g-zipped postscript file containing text and figure

Producing & Consuming Public Space: A ‘Rhythmanalysis’ of the Urban Park

Research suggests an opportunity to offer a more comprehensive analysis of temporal consumption experiences encountered by park users, and the subsequent contribution to a perceived ‘sense of place’. Using visual ethnography and rhythmanalysis, our study distances our analysis from textual accounts of park usage as well as provide policy recommendations

On the intersection of tolerance and cocomparability graphs.

It has been conjectured by Golumbic and Monma in 1984 that the intersection of tolerance and cocomparability graphs coincides with bounded tolerance graphs. Since cocomparability graphs can be efficiently recognized, a positive answer to this conjecture in the general case would enable us to efficiently distinguish between tolerance and bounded tolerance graphs, although it is NP-complete to recognize each of these classes of graphs separately. The conjecture has been proved under some – rather strong – structural assumptions on the input graph; in particular, it has been proved for complements of trees, and later extended to complements of bipartite graphs, and these are the only known results so far. Furthermore, it is known that the intersection of tolerance and cocomparability graphs is contained in the class of trapezoid graphs. In this article we prove that the above conjecture is true for every graph G, whose tolerance representation satisfies a slight assumption; note here that this assumption concerns only the given tolerance representation R of G, rather than any structural property of G. This assumption on the representation is guaranteed by a wide variety of graph classes; for example, our results immediately imply the correctness of the conjecture for complements of triangle-free graphs (which also implies the above-mentioned correctness for complements of bipartite graphs). Our proofs are algorithmic, in the sense that, given a tolerance representation R of a graph G, we describe an algorithm to transform R into a bounded tolerance representation R  ∗  of G. Furthermore, we conjecture that any minimal tolerance graph G that is not a bounded tolerance graph, has a tolerance representation with exactly one unbounded vertex. Our results imply the non-trivial result that, in order to prove the conjecture of Golumbic and Monma, it suffices to prove our conjecture. In addition, there already exists evidence in the literature that our conjecture is true
