Exploring predictors of performance on a curriculum-based measure of written expression
Madison Aitken,Rhonda Martinussen
Journal of Writing Research , 2013,
Abstract: This study examined the role of word-level reading proficiency and verbal working memory in grade 4 and 5 students’ (N = 42; 23 boys) performance on a curriculum-based measure of narrative writing. Two outcomes were measured: correct minus incorrect word sequences (CMIWS; accurate-production of spelling and grammar in-text), and composition quality. CMIWS scores were moderately correlated with the holistic quality score. Word reading proficiency predicted CMIWS above and beyond the variance accounted for by gender, grade, handwriting automaticity, and working memory. Word reading proficiency also predicted composition quality controlling for gender and handwriting automaticity. Working memory, as measured by an updating task, was not a significant unique predictor of CMIWS or composition quality. Grade (5 > 4) and gender differences (girls > boys) were also found for CMIWS scores. Although handwriting automaticity was correlated with CMIWS scores and writing quality, it was not a unique predictor of either measure. The results provide further evidence of the sensitivity of the CMIWS index. They also highlight the importance of considering reading proficiency and handwriting automaticity when assessing children’s writing abilities and planning instruction for children with writing difficulties.
Use of Web in Tertiary Research and Education
Wendy Aitken
Webology , 2007,
Abstract: The increasing level of official and academic information on Aboriginal issues on the Web enhances its utility in research and teaching. Aboriginal communities can also share Indigenous knowledges and perspectives, disseminate information to other indigenous communities and access the benefits of the knowledge society by adopting ICT. The use of search engines can save time in research and reveal trends in policy perspectives reflected by language.

An Auditory Illusion of Infinite Tempo Change Based on Multiple Temporal Levels
Guy Madison
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0008151
Abstract: Humans and a few select insect and reptile species synchronise inter-individual behaviour without any time lag by predicting the time of future events rather than reacting to them. This is evident in music performance, dance, and drill. Although repetition of equal time intervals (i.e. isochrony) is the central principle for such prediction, this simple information is used in a flexible and complex way that accommodates both multiples, subdivisions, and gradual changes of intervals. The scope of this flexibility remains largely uncharted, and the underlying mechanisms are a matter for speculation. Here I report an auditory illusion that highlights some aspects of this behaviour and that provides a powerful tool for its future study. A sound pattern is described that affords multiple alternative and concurrent rates of recurrence (temporal levels). An algorithm that systematically controls time intervals and the relative loudness among these levels creates an illusion that the perceived rate speeds up or slows down infinitely. Human participants synchronised hand movements with their perceived rate of events, and exhibited a change in their movement rate that was several times larger than the physical change in the sound pattern. The illusion demonstrates the duality between the external signal and the internal predictive process, such that people's tendency to follow their own subjective pulse overrides the overall properties of the stimulus pattern. Furthermore, accurate synchronisation with sounds separated by more than 8 s demonstrate that multiple temporal levels are employed for facilitating temporal organisation and integration by the human brain. A number of applications of the illusion and the stimulus pattern are suggested.

Counterexamples to the Hasse principle
Wayne Aitken,Franz Lemmermeyer
Mathematics , 2011,
Abstract: In this article we develop counterexamples to the Hasse principle using only techniques from undergraduate number theory and algebra. By keeping the technical prerequisites to a minimum, we hope to provide a path for nonspecialists to this interesting area of number theory. The counterexamples considered here extend the classical counterexample of Lind and Reichardt. As discussed in an appendix, this type of counterexample is important in the theory of elliptic curves: today they are interpreted as nontrivial elements in the Tate--Shafarevich group.
Splitting hybrid Make-To-Order and Make-To-Stock demand profiles
Wolfgang Garn,James Aitken
Statistics , 2015,
Abstract: In this paper a demand time series is analysed to support Make-To-Stock (MTS) and Make-To-Order (MTO) production decisions. Using a purely MTS production strategy based on the given demand can lead to unnecessarily high inventory levels thus it is necessary to identify likely MTO episodes. This research proposes a novel outlier detection algorithm based on special density measures. We divide the time series' histogram into three clusters. One with frequent-low volume covers MTS items whilst a second accounts for high volumes which is dedicated to MTO items. The third cluster resides between the previous two with its elements being assigned to either the MTO or MTS class. The algorithm can be applied to a variety of time series such as stationary and non-stationary ones. We use empirical data from manufacturing to study the extent of inventory savings. The percentage of MTO items is reflected in the inventory savings which were shown to be an average of 18.1%.
If Only Math Majors Could Write...

Numeracy , 2012,
Abstract: This text of the opening plenary address to the 2011 Summit of the Appalachian College Association and the meeting of the National Numeracy Network makes an argument that quantitative reasoning and writing should be taught together. The argument is set up by noting that humanists have historically banished quantitative issues from their study of the liberal arts and that science, engineering, and mathematics education suffers from lack of approaches to learning that promote complex, deeper understanding, most notably integrative and reflective learning. Therefore, everyone would profit from combining writing and quantitative reasoning. Five more specific reasons are discussed, drawing evidence from numerous sources among the twenty-nine references. The reasons given for combining quantitative constructs and language are: (1) To strengthen academic arguments; (2) To strengthen quantitative literacy/reasoning; (3) To interpret and improve public discourse; (4) To encourage quantitative reasoning across the curriculum; and (5) To prepare for the workplace. Underlying the basic argument and the reasons discussed are clear indications that, in present circumstances, teaching quantitative reasoning rests to a large extent on colleges and universities.

Testing superstring-inspired E(6) models at linear e+e- colliders
Manuel Drees,Madison
Physics , 1995,
Abstract: It is shown that in a large class of E(6) models, either an e+e- collider operating at $\rs \geq 1.5$ TeV must find a signal for the production of exotic leptons, or a collider operating at $\rs \geq 300$ GeV must find at least one light neutral Higgs boson with a large invisible branching ratio. The region of parameter space where neither of these signals is visible can be excluded because here the lightest neutral exotic lepton, which is absolutely stable, would overclose the Universe.
