An abstract notion of category of information systems or I-category is introduced as a generalisation of Scott's well-known category of information systems. As in the theory of partial orders, I-categories can be complete or !-algebraic, and it is shown that !-algebraic I-categories can be obtained from a certain completion of countable I-categories. The proposed axioms for a complete I-categor...

This research sought to investigate the validity of Rokeach's two-dimensional model of political ideology. In two separate studies, samples of Australian adults and university students were asked to complete the Social Values Inventory, a newly derived instrument designed to provide a more detailed coverage of the political ideology domain. Factor analyses of each set of data revealed a basic t...

Problem 5.53 of [18] (contributed by Wiegold, attributed to Scott) asks whether a free product of three (finite) cyclic groups can be normally generated by a single element. We give a proof of the conjectured negative answer, and an application to Dehn surgery on knots: if Dehn surgery on a knot in S3 gives a connected sum, then all but at most 2 of the connected summands are Z-homology spheres...

Most members of the genus Calaxias are small to mediumsized, fast-swimming, mid-water fishes that can be either lacustrine or diadromous (Whitley 1935). However, one species, Calaxias cleaveri Scott 1934, differs so markedly from typical Tasmanian members of the genus that at one stage it was referred to tpe genus Saxilaga by Scott (1936). Meristic and morphometric comparison of the mainland Ta...

The courses of many epidemic diseases reflect the social and economic changes in any nation. They are so often closely influenced by such problems as migrant labour, improving communications, movement of population, and rapid urbanisation. Ghana is no exception; the pattern of disease in that country is closely bound up with the history of its development-as this book well shows. Dr. Scott's ow...

T he second Pervasive Computing Education Workshop (PerEd 09; http://cseweb.ucsd.edu/~wgg/ PerEd2009) was held in conjunction with the 11th International Conference on Ubiquitous Computing (Ubicomp 09) in Orlando, Florida. It had been five years since the first PerEd workshop in 2004 (http://doi. ieeecomputersociety.org /10.1109/ PERCOMW.2004.10008) and six years since the formative Ubicomp Edu...

In this note we classify all triples (a, b, i) such that there is a convex lattice polygon P with area a, and b respectively i lattice points on the boundary respectively in the interior. The crucial lemma for the classification is the necessity of b ≤ 2 i+ 7. We sketch three proofs of this fact: the original one by Scott [12], an elementary one, and one using algebraic geometry. As a refinemen...

In the Paris Climate Agreement, countries worldwide committed to reduce greenhouse gas emissions by adopting more sustainable methods of energy use and supply. Yet, there are conflicting views on how to accomplish this goal and which energy sources, systems, and policies should be prioritized in a sustainable energy transition. In their book, Benjamin K. Sovacool, Marilyn A. Brown, and Scott V....

This paper aims to understand how Business Intelligence (BI) tools are used in the organizational environment in order to support the decision-making process. In this line of reasoning, the research method adopted was the single and exploratory Case Study undertaken in a financial company. The data analysis conducted in this research was based on the framework proposed by Keen & Scott-Morton (1...

In this paper, we rigorously prove the existence and stability of multiple spot patterns for the Gray-Scott system in a two dimensional domain which are far from spatial homogeneity. The Green's function together with its derivatives and two nonlocal eigenvalue problems both play a major role in the analysis. We establish a threshold behavior: If a certain inequality holds then we get stability...
