Deletions in open addressing tables have often been seen as problematic. The usual solution is to use a special mark ’deleted’ so that probe sequences continue past deleted slots, as if there was an element still sitting there. Such a solution, notwithstanding is wide applicability, may involve serious performance degradation. In the first part of this paper we review a practical implementation...

Editorials Two challenging articles in this issue of the Journal raise questions about public health practice, especially as we look from the past to the present and the future. By " public health practice, " we mean not so much the details of implementation or evaluation of specific programs, or the many other particulars that make up the daily tasks of public health practitioners; instead, we...

Many portfolio managers measure performance with reference to a benchmark. The difference in return between a portfolio and its benchmark is the active return of the portfolio. Portfolio managers and their clients want to know what caused this active return. Performance attribution decomposes the active return. The two most common approaches are the Brinson-Hood-Beebower (hereafter referred to ...

Critical literacy is widely practiced in classrooms in many countries and across levels of education. Research that explores critical literacy in English as a second language (ESL) and English as a foreign language (EFL) classrooms, however, remains scarce. The few studies that do exist focus on development of critical literacy without explicit attention to development of language skills (see, ...

Round Robin (RR) scheduling algorithm is a preemptive scheduling algorithm. It is designed especially for time sharing Operating System (OS). In RR scheduling algorithm the CPU switches between the processes when the static Time Quantum (TQ) expires. RR scheduling algorithm is considered as the most widely used scheduling algorithm in research because the TQ is equally shared among the processe...
