—Spotted Salamanders (Ambystoma maculatum) and members of the Blue-Spotted Salamander complex (Ambystoma laterale-jeffersonianum complex) often share terrestrial and wetland habitats, allowing controlled comparison of their life-history strategies. We examined population sizes, sex ratios, breeding frequencies, recruitment rates, and age structures, in sympatric populations of Spotted Salamande...

On behalf of my coauthors, I thank Dr. Drayman for his interest in our recent paper in which we examined whether plaques can contain more than one parental virus (1). We found that a small percentage of plaques (5 to 7%) contain multiple parental viruses, and we concluded that virion aggregation contributes to chimeric plaque formation. In a distinct flow cytometry-based assay that used a highe...

Many of the results in modern astrophysics rest on the notion that the Initial Mass Function (IMF) is universal. Our observations of a sample of H I selected galaxies in the light of Hα and the far-ultraviolet (FUV) challenge this result. The extinction corrected flux ratio FHα/ fFUV from these two tracers of star formation shows strong correlations with the surface-brightness in Hα and the R b...

In the sections below we review basic motivations for spatial statistical analysis, review three general categories of data structure and associated inferential questions, and describe Bayesian methods for achieving inference. Our goal is to highlight similarities across spatial analytic methods, particularly with regards to how hierarchical probability structures often link approaches develope...

This thesis covers experimental studies of atomic negative ions with the main goal of increasing our fundamental understanding of these fragile quantum systems. Comparisons of measurements and calculations have been used to increase our understanding of these highly correlated, yet simple, systems. All the described studies in this thesis have investigated the photodetachment process, i.e. when...

During non-generation periods, leakage through the wicket gates of a hydroturbine often results in very poor quality water (low or zero dissolved oxygen) in the tailrace of the hydropower facility. Generally, the leakage rate is relatively small, usually about 5-10 cfs per turbine. A bottom-mounted diffuser system was designed based on laboratory-measured and manufacturer-supplied specification...

Recently, microarrays technologies have been extensively used to distinguish gene expression in acute lymphoblastic leukaemia (ALL) (e.g. Pui et al., 2004; Hoffmann et al., 2008). ALL is the most common type of leukaemia diagnosed in children, with an incidence rate of about 4 per 100,000 per year (Pizzo and Poplack, 2001; Milne et al., 2008). There are six main subtypes of leukaemia, one of wh...

There is an exciting emerging research area in English Linguistics which concerns itself with current change, i.e. changes in the language that have taken place over relatively short spans of time, over decades rather than centuries, as is traditionally the case in diachronic linguistics. Changes across shorter periods of time have been studied in the past by a number of scholars, e.g. by Barbe...

Natural selection operated on the wild ancestors of crop plants for millions of years. Many seemingly intelligent design changes that we could make to enzyme structure or gene expression would duplicate (at least in phenotypic effect) variants already rejected by past natural selection. These variants died out because they decreased individual plant survival or reproduction under preagricultura...

This paper proposes the integration of The Competing Values Framework (Quinn 1984; 1988) with Nonaka and Takeuchi’s (1995) knowledge creation and conversion model. Conceptual parallels between the two models are identified and the interaction effects among dimensions are analysed. The resulting Organizational Knowledge Management Model should further understanding of the social and organization...
