Arousal And Activation Effects On Physiological And Behavioral Responding During A Continuous Performance Task, Jacqueline A. Rushby, Robert J. Barry, Adam R. Clarke, Mohammad Vaezmousavi

Faculty of Health and Behavioural Sciences - Papers (Archive)

Based on previous work indicating different neural substrates, two aspects of energetic state, arousal and activation, have been conceptualised separately in our laboratory. Arousal has been defined as the energetic state at any particular time, and task-related activation as the task-related change in state from resting baseline to the task situation. Both are reflected in electrodermal activity and measured by skin conductance level. Our previous studies in this area have indicated that physiological responses to stimuli in a task are dependent on the arousal level at the time of stimulus presentation, rather than the task-related activation. In contrast, performance on …

An Application Of A Psychometric Personality Type Inventory To Improve Team Development And Performance, Terence J. Froggatt, Nathan J. Bibby

Faculty of Health and Behavioural Sciences - Papers (Archive)

The issue of individual type preferences and how they relate to learning and human resource management are explored. Team learning, knowledge transfer, characteristics of leadership and trust and trusting in the context of team development and performance, are analyzed through the use of the Myers Briggs Type Indicator. The research is conducted with a semi professional Australian Rules football team. The team consists of a culturally diverse group. Predominantly, Australian men between the ages of 18 and 35 years. The men are university educated, trades professionals or blue collar workers, who volunteered to complete the Myers Briggs Type Indicator with …

The Effects Of Employment On Academic Performance Of Australian Accounting Students, Anura De Zoysa, Kathleen M. Rudkin

Faculty of Commerce - Papers (Archive)

This study examines factors that impact students engaged in paid employment while studying in a tertiary accounting program in a regional Australian university. It examines the differences in experience of domestic and international students. No direct significant relationship was found between paid employment and academic performance for the overall study sample. There was a positive relationship found between paid employment and academic performance with respect to domestic students. However, in the case of international students a negative relationship between paid employment and academic performance was observed. A significant positive relationship between a shift work pattern of paid employment and academic …

An Assessment Of The Research Performance Of Commerce Faculties In Australia, Abbas Valadkhani, Simon Ville

Faculty of Commerce - Papers (Archive)

There is a growing policy focus in Australian higher education on quantitative research performance assessment. However, most of the analysis has addressed aggregate performance at the institutional level, an approach inconsistent with recent policy emphasis on diversity among universities, and one that ignores performance variations across disciplines. We use cluster analysis to classify one of the ten broad fields of education, that is, management and commerce. Using averaged and available data for 2000-2004 on various research measures, partial rankings are provided. Factor analysis is utilised to generate full-multidimensional rankings within the resulting clusters. Our results show that low total research …

Does Ownership Affect A Firm's Performance And Default Risk In Jordan?, Rami Zeitun, Gary Gang Tian

Faculty of Commerce - Papers (Archive)

Purpose – This paper seeks to examine the impact of ownership structure on firm performance and the default risk of a sample of publicly listed firms.

Design/methodology/approach – This paper examines the impact of ownership structure on firm performance and the default risk of a sample of 59 publicly listed firms in Jordan from 1989 to 2002.

Findings – The main findings were: ownership structure has significant effects on the accounting measure of performance return on assets (ROE); government shares are significantly negatively related to the firm's performance ROE; defaulted firms have a high concentration ownership compared with non-defaulted firms …

Macroeconomic Determinants Of Corporate Performance And Failure: Evidence From An Emerging Market The Case Of Jordan, Rami Zeitun, Gary Tian, Steve Keen

Faculty of Commerce - Papers (Archive)

This study investigates the impact of aggregate economic risk on a company’s performance and failure in a panel estimation using 167 Jordanian companies during 1989-2003. Our finding shows that unanticipated changes in interest rate negatively and significantly affect firms’ performance measured by ROA, which suggests that an interest rate rise increases the cost of borrowing and then further negatively affects a firm’s profit. We also found that both the production manufacturing index and Islamic credit facilities positively and significantly affect a firm’s performance. The positive and significant impact of Islamic credit facilities reflects the importance and the significance of the …

Performance Comparison Of Subtractive Resistive Readout With Conventional Resistive Readout For A High-Resolution Compact Gamma Camera, Y J. Qi, M J. Zhang, C L. Zhao, R F. Wojcik

Faculty of Engineering and Information Sciences - Papers: Part A

The purpose of this study was to investigate an optimal readout for a high-resolution compact gamma camera with maximum performance in crystal element identifications. The compact camera is based on a pixellated Nal(Tl) crystal with 1.2 mm pixel size coupled to a 5" Hamamatsu R3292 PSPMT. A conventional resistive-chain readout was initially developed for the camera. Then a novel subtractive resistive readout developed was utilized to optimize the performance of the camera. The performance of the camera was evaluated by raw flood images of a 137Cs source. The results show that the conventional resistive readout results in a significant shrinkage …

On The Performance Of Short Forward Error-Correcting Codes, Sheng Tong, Dengsheng Lin, Aleksandar Kavcic, Li Ping, Baoming Bai

Faculty of Engineering and Information Sciences - Papers: Part A

This letter investigates the performance of short forward error-correcting (FEC) codes. Reed-Solomon (RS) codes and concatenated zigzag codes are chosen as representatives of classical algebraic codes and modern simple iteratively decodable codes, respectively. Additionally, random binary linear codes are used as a baseline reference. Our main results (demonstrated by simulations and ensemble distance spectrum analysis) are as follows: 1) Short RS codes are as good as random binary linear codes; 2) Carefully designed short low-density parity-check (LDPC) codes are almost as good as random binary linear codes; 3) Low complexity belief propagation decoders incur considerable performance loss at short coding …
