Renewal and Retraditionalisation

Note on Fuzzy Random Renewal Process and Renewal Rewards Process

Recently, Zhao et al. [Fuzzy Optimization and Decision Making (2007) 6, 279-295] characterized the interarrival times as fuzzy random variables and presented a fuzzy random elementary renewal theorem on the limit value of the expected renewal rate of the process in the fuzzy random renewal process. They also depicted both the interarrival times and rewards are depicted as fuzzy random variables...

Self-renewal and differentiation

The adult human heart has limited regenerative capacity and, theref fore, functional restoration of the damaged heart presents a great challenge. Despite the progress achieved in the pharmacological and surgical treatment of degenerative myocardial diseases, they are still considered a major cause of morbidity and mortality in the western world. Repopulation of the damaged heart with cardiomyof...

Renewal Theory

(1) Sn = S0 + n ∑ i=1 Xi When S0 = 0 the renewal process is an ordinary renewal process; when S0 is a nonnegative random variable the renewal process is a delayed renewal process. In either case, the individual terms Sn of this sequence are called renewals, or sometimes occurrences. With each renewal process is associated a renewal counting process N (t ) that tracks the total number of renewal...

Principal Leadership and School Renewal

Introduction The study upon which this paper is based solicited information on school renewal from a purposive sample of principals initially identified using quantitative profiling techniques (Silcox, Cavanagh and Dellar, 2003). Principals were presented with a series of questions that enabled an investigation of their leadership behaviours with respect to school renewal. The principals' respo...
