terazosin therapy for chronic prostatitis chronic pelvic pain syndrome a randomized placebo controlled trial
The Journal of Urology, 2003Co-Authors: Phaik Yeong Cheah, Men Long Liong, Kah Hay Yuen, Timothy Khor, Jin Rong Yang, John N KriegerAbstract:ABSTRACTPurpose: We evaluate terazosin therapy for chronic prostatitis/chronic pelvic pain syndrome.Materials and Methods: The study included 100, 20 to-50-year-old subjects who met the consensus criteria for chronic prostatitis/chronic pelvic pain syndrome and had not received previous α-blockers. Subjects were randomized to receive terazosin with dose escalation from 1 to 5 mg. daily or placebo for 14 weeks. The Primary Criterion for response was scoring 2 or less (“delighted-to-mostly satisfied”) on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) quality of life item. The secondary Criterion for response was greater than 50% reduction in NIH-CPSI pain score at 14 weeks. Other outcomes included total and NIH-CPSI domain scores, International Prostate Symptom Score, peak urinary flow rate, post-void residual urine and adverse effects.Results: Using the Primary Criterion 24 of 43 evaluable subjects (56%) responded in the terazosin group compared to 14 of 43 (36%) in the plac...

Single-machine hierarchical scheduling with release dates and preemption to minimize the total completion time and a regular Criterion
European Journal of Operational Research, 2020Co-Authors: Rubing Chen, Jinjiang Yuan, T.c.e. ChengAbstract:Abstract In this paper we consider the single-machine hierarchical scheduling problems with release dates and preemption, where the Primary Criterion is the total completion time and the secondary Criterion is an arbitrarily regular scheduling Criterion, which is of either the sum-form or the max-form. We aim to find a feasible preemptive schedule that minimizes the secondary Criterion, subject to the condition that the Primary Criterion is minimized. We show that the variants of the problems under study are polynomially solvable. To address these problems, we develop new solution techniques that establish some hereditary properties for the feasible schedules and instances, and present a complete description of the feasible schedules through some elaborately constructed job-permutations.

On the complexity of bi-criteria scheduling on a single batch processing machine
Journal of Scheduling, 2010Co-Authors: L. L. Liu, T.c.e. ChengAbstract:This paper considers hierarchical bi-criteria scheduling on a single batch processing machine where the Primary Criterion is the makespan. We show that the problem where the secondary Criterion is the total completion time can be solved in polynomial time for a given machine capacity and the problem where the secondary Criterion is the (weighted) number of late jobs is (strongly) NP-hard.

An Improved Solution Procedure for the Scheduling Problem
Journal of the Operational Research Society, 1991Co-Authors: T.c.e. ChengAbstract:Given a set of n jobs to be processed on a single machine, the problem is to find an optimal job sequence that hierarchically minimizes a bi-Criterion objective function. The Primary Criterion is the maximum value of a general non-decreasing penalty function of job completion time, while the secondary Criterion is total job flow time. An extension of Emmons's result is presented on the basis of which an improved solution procedue is developed to reduce the computational effort to find the optimal solution.

should scholarly productivity be the Primary Criterion for tenure decisions no
Journal of Social Work Education, 1992Co-Authors: Ann WeickAbstract:social work training programs within universities came at a critical juncture in our professional history. With that one step, social work joined the budding social sciences and other professions and moved away from its origins in philanthropy, theology and moralism. The scientific model adapted from the physical sciences was seen as the new beacon to guide knowledge development about the human and social worlds. Social work thus en

SOME IMPROVED ALGORITHMS ON THE SINGLE MACHINE HIERARCHICAL SCHEDULING WITH TOTAL TARDINESS AS THE Primary Criterion
Asia-Pacific Journal of Operational Research, 2010Co-Authors: Yixun Lin, Jinjiang YuanAbstract:It is well-known that a single machine scheduling problem of minimizing the total tardiness is NP-hard. Recently, Liu, Ng and Cheng solved some special hierarchical minimization problems with total tardiness as the Primary Criterion by the Algorithm TAP (Two Assignment Problems) in O(n3) time. And in this paper we present some algorithms for these problems with running time O(n log n).
