The following papers evolved as a continuing discussion begun by John Harris in his paper “Stem Cells, Sex, and Procreation” (CQ Vol 12, No 4). First, Julian Savulescu responds to the Harris paper, with Harris following with a response to Savulescu. Next, the two authors suggested a joint paper in which, despite their continuing differences, they would examine where they agree. This remarkable ...

Feature-points matching is an important concept in binocular stereo vision. The procession of multi-scale feature-points matching in classical Harris-SIFT algorithm is time-consuming and has high complexity when describing the feature-points. This paper proposed a new improved Harris-SIFT algorithm based on rotation-invariant LBP (Local binary patterns) operator. Firstly, the Harris operator is...

In this paper, we study parametric nonlinear regression under the Harris recurrent Markov chain framework. We first consider the nonlinear least squares estimators of the parameters in the homoskedastic case, and establish asymptotic theory for the proposed estimators. Our results show that the convergence rates for the estimators rely not only on the properties of the nonlinear regression func...

This paper criticises John Harris's attempts to defend an account of a 'harmed condition' that can stand independently of intuitions about what is 'normal'. I argue that because Homo sapiens is a sexually dimorphic species, determining whether a particular individual is in a harmed condition or not will sometimes require making reference to the normal capacities of their sex. Consequently, Harr...

This paper describes the authors’ hypothesis that software development organizations operate at different levels in a hierarchy of needs modeled on the Maslow Hierarchy of needs. The Harris Hierarchy of Software Development Needs has four levels representing operating states of the software development organization: Failure, Fear of Failure, Control and Value. The paper describes how the new mo...

Improving the prognosis of ovarian cancer patients is a major challenge to scientists and clinicians. At a recent multidisciplinary meeting in Washington DC, advances in identification of precursor lesions, progress in disease biomarkers and animal models, the promise of nanotechnology, and strategies for manipulation of the innate and adaptive immune response offered prospects for real progres...

We develop an algorithm for simulating \perfect" random samples from the invariant measure of a Harris recurrent Markov chain. The method uses backward coupling of embedded regeneration times, and works most eeectively for nite chains and for stochas-tically monotone chains even on continuous spaces, where paths may be sandwiched below \upper" and \lower" processes. Examples show that more naiv...

This paper uses the Harris-Todaro model of rural-urban migration to explore how inequality is likely to evolve during the course of various kinds of economic development. It is shown that development in agriculture is likely to be reduce inequality. The paper also shows that the Kuznets curve is unlikely to be a general result, and clari¿es the reasons for the observed link between dualism and ...
