Helping students take control of their learning through the use of focused weekly review sheets
(TESOLANZ, 2001)This paper reports on work done with students enrolled in a Level 4 Certificate of Attainment in English (CAEL) class at the University of Waikato Language Institute in Auckland. The original purpose was to help raise the ... 
Hector Berlioz's Les Nuits d'été: A performer's perspective
(National Association of Teachers of Singing, 2005) 
On phiDedekind rings and phiKrull rings
(University of Houston, 2005)The purpose of this paper is to introduce two new classes of rings that are closely related to the classes of Dedekind domains and Krull domains. Let H = {R  R is a commutative ring with 1 and Nil(R) is a divided prime ... 
Climbing Grammar Mountain: An Interactive Learning Experience
(United States Department of State, 2005)This article describes a grammar game that is an enjoyable way for students to correct sentences. In Climbing Grammar Mountain, best suited for secondary and university students, learners compete in teams to "climb" a game ... 
On phiMori rings
(University of Houston, 2006)A commutative ring R is said to be a phiring if its nilradical Nil(R) is both prime and comparable with each principal ideal. The name is derived from the natural map phi from the total quotient ring T(R) to R localized ... 
On the periodic logistic equation
(Elsevier, 2006)We show that the 𝒑periodic logistic equation 𝒳ₙ₊₁ = μₙ mod 𝒑𝒳ₙ(1  𝒳ₙ) has cycles (periodic solutions) of minimal periods 1; 𝒑; 2𝒑; 3𝒑; …. Then we extend Singer’s theorem to periodic difference equations, and use ... 
Strong ring extensions andphipseudovaluation rings
(University of Houston, 2006)In this paper, we extend the concept of strong extensions of domains to the context of (commutative) rings with zerodivisors. We show that the theory of strong extensions of rings resembles that of strong extensions of domains. 
An Extension of Sharkovsy’s Theorem to Periodic Difference Equations
(Elsevier, 2006)We present an extension of Sharkovsky’s Theorem and its converse to periodic difference equations. In addition, we provide a simple method for constructing a pperiodic difference equation having an rperiodic geometric ... 
Richard Wagner's Wesendonck Lieder: Isolde Personified
(National Association of Teachers of Singing, 2006) 
Martingale problem for superprocesses with nonclassical branching functional
(Elsevier, 2006)The martingale problem for superprocesses with parameters (𝛏, Ф, 𝑘) is studied where 𝑘(𝒹𝑠) may not be absolutely continuous with respect to the Lebesgue measure. This requires a generalization of the concept of ... 
Antibacterial selfassembled nanotubes of cyclic d, lalphapeptides
(AIP Publishing, 2007)Cyclic D, L‐α‐peptides can be designed to spontaneously partition into lipid and cell membranes where they self‐assemble into membrane‐permeating nanotubes and result in disruption of membrane potentials leading to rapid ... 
Existence and stability of periodic orbits of periodic difference equations with delays
(World Scientific Publishing, 2008)In this paper, we investigate the existence and stability of periodic orbits of the pperiodic difference equation with delays xₙ = f(n  1, xₙ₋ₖ). We show that the periodic orbits of this equation depend on the periodic ... 
Exercisability Randomization of the American Option
(Taylor & Frances Online, 2008)The valuation of American options is an optimal stopping time problem which typically leads to a free boundary problem. We introduce here the randomization of the exercisability of the option. This method considerably ... 
Periodic Orbits in Periodic Discrete Dynamics
(Elsevier, 2008)We study the combinatorial structure of periodic orbits of nonautonomous difference equations 𝒳ₙ₊₁ = 𝒇ₙ(𝒳ₙ) in a periodically fluctuating environment. We define the Ӷset to be the set of minimal periods that are not ... 
Emerging Pedagogies in the Middle East: Enhancing Student Autonomy Using Weblogs (Blogs)
(The University of Buckingham Press, 2008)Students in the Middle East have typically been taught English following traditional, rote learning methods. There has been little time, or little room, within the set curriculum for teachers to enrich their students’ ... 
Some finiteness conditions on the set of overrings of a phiring
(University of Houston, 2008)Let H = {R  R is a commutative ring and Nil(R) is a divided prime ideal of R}. For a ring R in H with total quotient ring T(R), Let phi be the natural ring homomorphism from T(R) into R_Nil(R). An integral domain R is ... 
Coexistence and extinction in a competitive exclusion Leslie/Gower model with harvesting and stocking
(Taylor & Francis Online, 2009)The principle of competitive exclusion states that when the competition between species is sufficiently strong, only the dominant species survives. In this paper, we examine the strategies of using stocking and harvesting ... 
The Beverton–Holt model with periodic and conditional harvesting
(Taylor & Francis Online, 2009)In this theoretical study, we investigate the effect of different harvesting strategies on the discrete Beverton–Holt model in a deterministic environment. In particular, we make a comparison between the constant, periodic ... 
Becomings in J. M. Coetzee's Waiting for the Barbarians and José Saramago's Blindness
(The Pennsylvania State University, 2010) 
The Discrete BevertonHolt Model with Periodic Harvesting in a Periodically Fluctuating Environment
(Springer, 2010)We investigate the effect of constant and periodic harvesting on the BevertonHolt model in a periodically fluctuating environment. We show that in a periodically fluctuating environment, periodic harvesting gives a better ...
