Mental Models For The Negation Of Conjunctions And Disjunctions, Guillermo Macbeth, Eugenia Razumiejczyk, María C. Crivello, Claudia Bolzán, Carolina I. Pereyra Girardi, Guillermo Campitelli Jan 2014

Mental Models For The Negation Of Conjunctions And Disjunctions, Guillermo Macbeth, Eugenia Razumiejczyk, María C. Crivello, Claudia Bolzán, Carolina I. Pereyra Girardi, Guillermo Campitelli

Research outputs 2014 to 2021

This study investigates why reasoning that involves negation is extremely difficult. We presented participants with reasoning problems containing sentences with negation of conjunctions and disjunctions in order to test predictions derived from the Mental Models Theory of human thought. According to this theory, reasoning consists of representing and comparing possibilities. Different sentential forms would require different cognitive demands. In particular, responses to a sentential negation task would be modulated by working memory load. This prediction would hold for correct responses but also for the general pattern of responses that includes incorrect responses when the task offers different response options. A …

Exchange Rate Exposure Of Sectoral Returns And Volatilities: Further Evidence From Japanese Industrial Sectors, Prabhath Jayasinghe, Albert K. Tsui, Zhaoyong Zhang Jan 2014

Exchange Rate Exposure Of Sectoral Returns And Volatilities: Further Evidence From Japanese Industrial Sectors, Prabhath Jayasinghe, Albert K. Tsui, Zhaoyong Zhang

Research outputs 2014 to 2021

In this paper we argue that the commonly employed exposure coefficient/beta is inadequate for capturing the entire impact of exchange rate changes on firms' future operating cash flows. Instead, we employ the bivariate Glosten-Jagannathan-Runkle generalized autoregressive conditional heteroskedasticity mean model to investigate four aspects of exchange rate exposure, including sensitivity of stock returns to exchange rate changes, sensitivity of stock returns to the volatility of exchange rate changes, sensitivity of conditional variance of returns to exchange rate volatility, and the dynamic conditional correlation between returns and exchange rate changes, respectively, using data from 10 industrial sectors in Japan. We find …

Characterizing The Resolvability Of Real Superluminescent Diode Sources For Application To Optical Coherence Tomography Using A Low Coherence Interferometry Model, Paul V. Jansz, Steven Richardson, Graham Wild, Steven Hinckley

Research outputs 2014 to 2021

The axial resolution is a critical parameter in determining whether optical coherent tomography (OCT) can be used to resolve specific features in a sample image. Typically, measures of resolution have been attributed to the light source characteristics only, including the coherence length and the point spread function (PSF) width of the OCT light sources. The need to cost effectively visualize the generated PSF and OCT cross-correlated interferogram (A-scan) using many OCT light sources have led to the extrinsic evolution of the OCT simulation model presented. This research indicated that empirical resolution in vivo, as well as depending on the light …

Research outputs 2014 to 2021

We examined the distribution of zinc in the periphery (erythrocytes and serum) in a large, well-characterised cohort, the Australian Imaging, Biomarkers and Lifestyle (AIBL) study, in order to determine if there is systemic perturbation in zinc homeostasis in Alzheimer’s disease (AD). We observed an age dependent decrease in serum zinc of approximately 0.4% per year. When correcting for the age dependent decline in serum zinc no significant difference between healthy controls (HC), mildly cognitively impaired (MCI) or AD subjects was observed.

A Process-Oriented Measure Of Habit Strength For Moderate-To-Vigorous Physical Activity, J. Robert Grove, Irja Zillic, Nikola Medic

Research outputs 2014 to 2021

Habitual action is an important aspect of health behaviour, but the relevance of various habit strength indicators continues to be debated. This study focused specifically on moderate-to-vigorous physical activity (MVPA) and evaluated the construct validity of a framework emphasizing patterned action, stimulus-response bonding, automaticity, and negative consequences for nonperformance as indicators of habit strength for this form of exercise. Methods: Upper-level undergraduates (N = 124) provided demographic information and responded to questionnaire items assessing historical MVPA involvement, current MVPA involvement, and the four proposed habit strength dimensions. Factor analyses were used to examine the latent structure of the habit strength …

Research outputs 2014 to 2021

This paper describes discipline-specific transition support utilised to follow-up the Post-Entry Language Assessment (PELA) recently introduced at Edith Cowan University as one strategy to address declining rates of English language proficiency. Transition support was embedded within a first year core unit and emphasis was placed on assisting students to develop spoken and written communicative competencies by scaffolding assessment tasks and providing other academic supports that used contextualised examples. While general satisfaction with the academic support offered during the course was high, the program achieved limited success in encouraging at-risk students to seek support. Further investigation into methods of encouraging student …

Teachers And Teacher Aides Initiating Five-Year-Olds Into Science, Anne M. Thwaite

Research outputs 2014 to 2021

Apprenticing children into discourses necessary for success at school begins at a very early age. In this paper I look at five-years-olds being introduced to Science and Technology while at the same time being involved in talk around literacy. The various adults who surround the children engage differentially in talk and action while merging the discourses of literacy and science. Data for this study were obtained during the course of the project ‘Early literacy through science in Indigenous and culturally diverse communities’, funded by Edith Cowan University in Australia from 2009–2010, in which the author was involved as a researcher. …

Research outputs 2014 to 2021

Dissolved cobalt (DCo; 0.2μm; 10%) to the DCo stock of the mixed layer in the equatorial and north subtropical domains. Biotic and abiotic processes as well as the physical terms involved in the biogeochemical cycle of Co were defined and estimated. This allowed establishing the first global budget of DCo for the upper 100m in the western Atlantic. The biological DCo uptake flux was the dominant sink along the section, as reflected by the overall nutrient-type behavior of DCo. The regeneration varied widely within the different biogeochemical domains, accounting for 10% of the DCo-uptake rate in the subarctic gyre and …

Mori, Lawrence J. Beilin, Wendy H. Oddy, Alexandra P. Bremner, Therese A. O'Sullivan

Research outputs 2014 to 2021

Almost all previous studies examining the associations between glycaemic load (GL) and metabolic syndrome risk have used a daily GL value. The daily value does not distinguish between peaks of GL intake over the day, which may be more closely associated with the risk of the metabolic syndrome. The aim of the present study was to investigate the cross-sectional associations between daily and mealtime measures of GL and metabolic syndrome risk, including metabolic syndrome components, in adolescents. Adolescents participating in the 14-year follow-up of the Western Australian Pregnancy Cohort (Raine) Study completed 3 d food records and metabolic assessments. Breakfast …

Research outputs 2014 to 2021

In golf, many parameters of the driver can be modified to maximise hitting distance. The main objective of this study was to determine whether drivers fitted with shafts having high and low kick points would alter selected swing parameters and related launch conditions. In total, 12 elite male golfers (handicap score = 1.2 ± 1.8) had three shots analysed for two drivers fitted with 'stiff' shafts with differing kick point location. Stiffness profiles of these shafts were also measured. Five swing and related launch parameters were measured using a real-time launch monitor. The locations of the low and high kick …
