Culture and Information Security Awareness: Examining the Role of Organisational and Security Culture

This item is only available electronically.The relationship between security culture and ISA has received preliminary support; however, its interplay with organisational culture is yet to be empirically explored. Therefore, this study examined the relationship between ISA, organisational culture, and security culture. A total of 508 working Australians completed an online questionnaire. ISA was measured using the Human Aspects of Information Security Questionnaire (HAIS-Q); organisational culture was measured using the Denison Organisational Culture Survey (DOCS); and security culture was assessed through the Organisational Security Culture Measure. Our results showed that while organisational culture and security culture were correlated with ISA, security culture mediated the relationship between organisational culture and ISA. This finding has important applied implications. Organisations can improve ISA by focussing on security culture rather than organisational culture, saving them time and resources. Future research could further extend current findings by also considering national culture.Thesis (M.Psych(Organisational & Human Factors)) -- University of Adelaide, School of Psychology, 201

Effects of High-Velocity versus Low-Velocity Resistance Training on Resting Metabolic Rate and Functional Performance in Older Adults

The purpose of this study was to compare the effects of a 12-week high-velocity resistance training (HVRT) protocol to a traditional low-velocity resistance training (LVRT) protocol on resting metabolic rate (RMR) and other selected measures of muscular and functional fitness in older adults. Nineteen adults between the ages of 65 and 82 participated: 8 HVRT, 7 LVRT, and 4 controls (CTRL). Initially, no differences existed between groups except for age (p = .016). HVRT (75.6 years) was older than LVRT (69.6 years) and CTRL (69.3 years). The exercise intervention consisted of 2 days/week sessions for 12 weeks at 3 sets of 10 repetitions progressing to 80% 1RM for leg press, leg curl, leg extension, upper back, chest press, and shoulder press on Keiser pneumatic resistance machines. CTRL participants walked throughout the 12 weeks. Pre- and post-intervention strength, power (leg extension at 180°/sec), RMR, body composition, and functional fitness (30-sec chair stand and 8-ft up-and-go) were measured. Data were analyzed by a repeated measures analysis of variance (ANOVA) and effect sizes. All groups decreased RMR: LVRT by 11.4%, HVRT 15.6%, and CTRL 31.1% (p = .039 between groups). While CTRL lost 5.3% of FFM, HVRT increased 0.7% and LVRT 3.1% (p = .012). All groups increased in power but were not significantly different: CTRL by 3.0%, LVRT 8.7%, and HVRT 11.7% (p = .830). For total lower body strength, CTRL increased by 5.6%, LVRT by 42.3%, and HVRT by 44.6% (p = .016). No significant interaction between time and group was found for chair stand (p = .739) or up-and-go (p = .283). Overall, this study indicates LVRT and HVRT over a 12-week period at 80% 1RM produce similar changes in RMR, FFM, strength, and power

Using Sport to Build Community: Service-Learning with Iraqi Refugees

The purpose of this study was to explore the connections between Sport for Development and Peace (SDP), service-learning, and community-university partnerships through the implementation of the Service-Learning: Sport and Community Development (SCD) class. It was my hope that this research would produce a usable model, a framework for other scholars and practitioners interested in developing community-university partnerships. I wanted this project to not only answer the “why” questions for SDP and service-learning, but also the “how” questions – specifically, how to create a reflexive and collaborative partnership that balances the needs of the community and university. I wanted to create something riveting and real, something inspiring and authentic, and something more inclusive than a first-person programmer or instructor account of the experience (Darnell, 2007; Eyler & Giles, 1999; Millington, 2010; Stoecker & Tryon, 2009). Much like the goals of the class, this research was designed to stimulate and encourage others to move toward a more critical and engaged community agenda. To do that, I needed to create a research text that readers could “keep in their minds and feel in their bodies the complexities of concrete moments of lived experience” (Ellis, 2004, p. 30). For that reason, I chose narrative inquiry (Clandinin & Connelly, 2000) as the primary method of representation, coupled with performance narratives (Denzin, 2003) and poetics (Glesne, 2006; Ely, 2007). Based on the data collected from 49 qualitative interviews, 500 pages worth of reflective journals, and 200 pages of electronically recorded field notes, I created a visual community-university partnership model that illustrates the connections between SDP and service-learning as implemented in the SCD class. In addition to the visual model, I constructed narratives to detail the progression of the SCD experience over time, beginning with the common language of sport and ending in complete investment and reciprocity. As a result of this research, it has become clear that if implemented with intentionality, careful consideration, community collaboration, and reflexivity, that sport-based service-learning initiatives can enhance student learning, improve community welfare, and strengthen ties between the community and the university

Calling time: How to remove fossil fuel sponsorships from sports, arts & events

Sports, arts and major events are deeply embedded in the Australian way of life. Weekend matches, concerts and festivals bring us together - to cheer, to share pride and excitement, to feel connected to each other and to keep building our national story. When we barrack for our beloved teams, discover the work of a new local artist or laugh until our cheeks hurt at a comedy show, we are taking part in a ritual that has shaped social and cultural life in Australia for generations. Climate change – driven by burning coal, oil and gas – is putting all of this at risk. From flooded festivals, to concerts cancelled by bushfire threats and unsafe heat disrupting play at the tennis, footy and more, climate change is wreaking havoc on the activities and events we love..

Spatial and temporal (non)binding of audio-visual stimuli: effects on motor tracking and underlying neural sensory processing

Objectives: Compare the steady-state evoked potentials (SSEPs) of spatially or temporally congruent and incongruent audio-visual stimuli and evaluate how congruency affects the motion tracking of visual stimuli. Research question: Does spatial or temporal congruency of audio-visual stimuli affect motion tracking and evoke differential SSEPs? Methods: We use EEG frequency-tagging techniques to investigate the selective neural processing and integration of visual and auditory information in the tracking of a moving stimulus and how spatial and temporal (in)congruency between the two modalities modulate these sensory neural processes and synchronization performance.Participants were instructed to track a red dot flickering at 15 Hz that oscillated horizontally with a complex trajectory on a computer screen by moving their index finger. An auditory pure tone with continuous pitch modulation at 32 Hz was presented with lateralised amplitude modulations in left and right audio channels (panning) that were, in Experiment 1, either spatially congruent or incongruent (same direction vs. opposite direction vs. no panning), and in Experiment 2, either temporally congruent or incongruent (no delay vs. medium or large delay), with the oscillating visual stimulus. Results: Both experiments yielded significant EEG responses at the visual (15 Hz) and auditory (32 Hz) tagging frequencies. Further, in Experiment 1 participants had lower performance and larger amplitudes at the auditory frequency during no panning condition. No significant correlation between the two measures was found. In Experiment 2 no changes in the amplitude of the EEG responses or in performance were found. Conclusion: The movement synchronization performance and the neural processing of visual and auditory information were not influenced by phase congruency manipulation. For spatial congruency, the moving auditory stimuli led to better performance, irrespective of congruency, when compared to the non moving sound. Importantly, there were no significant responses at 17 and 47 Hz corresponding to the intermodulation frequencies of 15 and 32 Hz, suggesting an absence of global integration of visual and auditory information. These results encourage further exploration of the conditions that may result in the selective processing of visual and auditory information and their integration in the motor tracking of moving environmental objects

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
