Self-directed learning has been a central topic of discussion in adult education for many years. After analyzing several articles and books regarding autonomous learning, I have taken a stance of my own on the matter. In the sections that follow I have summarized my readings of Gerald Grow and Mark Tennant’s articles regarding self-directed learning, to include an explanation of my position on ...

Rubber bush (Calotropis procera), a perennial invasive milkweed, infests large swathes of pastoral land in northern Australia and Queensland, diminishing pasture productivity. The seeds rubber are small with fluffy pappi that confer buoyancy during wind dispersal. Long-distance seed dispersal (LDD) by is dependent part on terminal velocity, the height release above ground, surrounding vegetatio...

Abstract. Strontium isotopes (87Sr/86Sr) are useful to trace processes in the Earth sciences as well forensic, archaeological, palaeontological, and ecological sciences. As very few large-scale Sr isoscapes exist Australia, we have identified an opportunity determine 87Sr/86Sr ratios on archived fluvial sediment samples from low-density National Geochemical Survey of Australia. The present stud...

A lthough the term stress as it relates to the human condition has been in the scientific literature since the 1930s and in the nursing literature since the late 1950s, the word did not become popular vernacular until the late 1970s and early 1980s. Today, the term is used in everyday vocabulary to capture a variety of human experiences that are disturbing or disruptive in some manner: “You wou...

Individuals with borderline personality disorder (BPD) often experience stressful life events at a higher frequency than those without BPD. It is less clear what specific types of events are involved in this effect, and it has not been determined whether some features of BPD are more important than others in accounting for this effect. The latter issue is important in light of the heterogeneous...

ABSTRAC~ National Institute of Environmental Health Sciences researchers are exploring the utility of genetically altered mice to study mechanisms of carcinogenesis. Two of these mouse models, the Tg.AC (carrier of an activated mouse H-ms oncogene) and the p53+ (heterozygous for the wild-type tumor suppressor gene Trp53), have genetic alterations that appear to hasten their expression of chemic...

In this paper I take a closer look at a recently published paradox by Göran Sundholm involving the notion of knowability. I point out that this paradox is not a novel, genuine paradox, but rather an important variant of the Knower Paradox. I briefly discuss further variations of the Knower Paradox, and in a final section I try to show that it is not unproblematic to assume that knowability is f...

We discuss a variety of roles for diagrams in helping with reasoning, focusing in particular on their role as physical models of states of affairs, much like an architectural model of a building or a 3-D molecular model of a chemical compound. We discuss the concept of a physical model for a logical sentence, and the role played by the causal structure of the physical medium in making the given...
