A retrospective evaluation of attitudinal, behavioural and knowledge change among diverse stakeholder groups was conducted in Limpopo Province of South Africa to assess the effectiveness of a series of values clarification (VC) interventions. Telephone and face-to-face interview (193) results revealed that over two-thirds (70.2%) reported behavioural changes and 93.2% reported increased compass...

The K-Mode algorithm is known for applications on categorical datasets but with few drawbacks like selecting random k value, efficiency on cluster accuracy and so on. This paper provides research study on extension and modification of K-mode algorithm to provide good initial starting mean to get better clusters with better accuracy results on categorical data domains. The proposed algorithm has...

A Sierpiński number is an odd integer k with the property that k ·2+1 is composite for all positive integer values of n. A Riesel number is defined similarly; the only difference is that k · 2 − 1 is composite for all positive integer values of n. In this paper we find Sierpiński and Riesel numbers among the terms of the wellknown Fibonacci sequence. These numbers are smaller than all previousl...

In this paper explicit expressions and some recurrence relations are derived for marginal and joint moment generating functions of generalized order statistics from Erlang-truncated exponential distribution. The results for k-th record values and order statistics are deduced from the relations derived. Further, a characterizing result of this distribution on using the conditional expectation of...

BACKGROUND Although the Netherlands currently has its own procedure for evaluating chemical compounds and setting occupational exposure limits (OELs), most of these limits were originally adopted in the 1970s from threshold limit values (TLVs) set by the American Conference of Governmental Industrial Hygienists (ACGIH). However, beginning in the late 1980s, criticism about non-scientific consid...
