Using Dual Eye Tracking To Uncover Personal Gaze Patterns During Social Interaction, Shane L. Rogers, Craig P. Speelman, Oliver Guidetti, Melissa Longmuir

Research outputs 2014 to 2021

We report the personal eye gaze patterns of people engaged in face-to-face getting acquainted conversation. Considerable differences between individuals are underscored by a stability of eye gaze patterns within individuals. Results suggest the existence of an eye-mouth gaze continuum. This continuum includes some people showing a strong preference for eye gaze, some with a strong preference for mouth gaze, and others distributing their gaze between the eyes and mouth to varying extents. Additionally, we found evidence of within-participant consistency not just for location preference but also for the duration of fixations upon the eye and mouth regions. We also estimate …

The Impact Of Targeted Educational Programmes On Academic Outcomes For African Students In Western Australia, Kwadwo Adusei-Asante

Research outputs 2014 to 2021

Over the past two decades, people with African backgrounds have become part of Australian society. There have been extensive discussions of the various academic challenges African students experience at all educational levels in Australia. The academic challenges identified range from low academic achievement to unemployment and are particularly prevalent among African students who are refugees or those who have low socio-economic status. This paper argues that targeted educational programmes need to be implemented to support African students who are struggling in their academic pursuits. The positive outcomes and lessons learned from our implementation of the Top-Up Programme, a peer-mentoring educational …

Improving Security Message Adherence Through Improved Comprehension: Neural And Behavioral Insights, Bonnie Brinton Anderson, Daniel Bjornn, Jeffrey Jenkins, C. Brock Kirwan, Anthony Vance

Faculty Publications

Security warnings are critical to help users make contextual security decisions. Unfortunately, users find these warnings hard to understand, and they routinely expose themselves to unintended risks as a result. Although it is straightforward to determine when users fail to understand a warning, it is more difficult to pinpoint why this happens. The goal of this research is to use eye tracking to step through the building blocks of comprehension—attention, semantics, syntax, and pragmatics—for SSL and other common security warnings. Through this process, we will identify ways to design security warnings to be more easily understood.

How Does Destination Social Responsibility Contribute To Environmentally Responsible Behaviour? A Destination Resident Perspective, Lujun Su, Songshan (Sam) Huang, Joanna Pearce

Research outputs 2014 to 2021

Based on stakeholder theory and social exchange theory, this study developed an integrated model to demonstrate that destination social responsibility (DSR) influences tourism impacts (both positive and negative impacts), overall community satisfaction, and both directly and indirectly influences resident environmentally responsible behaviour (ERB). The model was examined using a sample of 453 residents living on the Gulangyu Island, a famous island tourism destination of Xiamen, China. Results show that DSR enhances residents’ perception of positive tourism impacts, improves overall community satisfaction and contributes to resident ERB. However, the effect of DSR on negative tourism impacts was not significant. Thus, positive …

Emotions Predict Policy Support: Why It Matters How People Feel About Climate Change, Susie Wang, Zoe Leviston

Research outputs 2014 to 2021

Current research shows that emotions can motivate climate engagement and action, but precisely how has received scant attention. We propose that strong emotional responses to climate change result from perceiving one's “objects of care” as threatened by climate change, which motivates caring about climate change itself, and in turn predicts behaviour. In two studies, we find that climate scientists (N = 44) experience greater emotional intensity about climate change than do students (N = 94) and the general population (N = 205), and that patterns of emotional responses explain differences in support for climate change policy. Scientists tied their emotional …

Are Current Effectiveness Criteria Fit For Purpose? Using A Controversial Strategic Assessment As A Test Case, Jenny Pope, Alan J. Bond, Carolyn Cameron, François P. Retief, Angus N. Morrison-Saunders

Research outputs 2014 to 2021

The aim of this paper is to test the broader utility of the sustainability assessment effectiveness framework of Bond et al. (2015) by applying it to a controversial strategic assessment case study. The effectiveness framework comprises six dimensions: procedural effectiveness, substantive effectiveness, transactive effectiveness, normative effectiveness, pluralism, and knowledge and learning. It was originally developed to evaluate sustainability assessment at a system-wide level and it has not been previously applied to a specific case study. The analysis was conducted through document review and the first-hand experience of two of the authors who were involved in the case study …

Research outputs 2014 to 2021

Aims and objectives: To explore the connection between +6 nursing leadership and enhanced patient safety.

Background: Critical reports from the Institute of Medicine in 1999 and Francis QC report of 2013 indicate that healthcare organisations, inclusive of nursing leadership, were remiss or inconsistent in fostering a culture of safety. The factors required to foster organisational safety culture include supportive leadership, effective communication, an orientation programme and ongoing training, appropriate staffing, open communication regarding errors, compliance to policy and procedure, and environmental safety and security. As nurses have the highest patient interaction, and leadership is discernible at all levels of nursing, …

Towards An Improved Typology Approach To Segmenting Cultural Tourists, Ganghua Chen, Songshan (Sam) Huang

Research outputs 2014 to 2021

This study aims to improve the cultural tourist typology methodology that uses cultural centrality and depth of cultural experience in its framework. Using a sample of Chinese tourists in Macau (n = 595) collected via questionnaire surveys, the study confirmed the determination effect of cultural centrality on depth of cultural experience. Subsequently, the study demonstrated an improved approach that eliminates such a determination effect in typology identification. Compared to McKercher's () approach, the improved typology presents a balanced segmentation of cultural tourists and distinguishes the segments more clearly in their sociodemographic characteristics. The improved typology generated more meaningful practical implications.

The Effect Of Software Team Personality Composition On Learning And Performance: Making The “Dream” Team, Greg Anderson, Mark J. Keith, Julianne Francisco, Sarah Fox

Faculty Publications

Optimizing work team composition in organizational and educational environments is an important task toward maximizing performance. Social science research has revealed that personality trait composition influences team cohesion and performance. However, this research has not been well-adapted into the IS context. In addition, prior research demonstrates how individual personality traits impact teams, but fails to appropriately characterize overall team personality composition. We expand this research by 1) characterizing holistic personality compositions, and 2) examining team learning in addition to performance in the IS context. We draw from theory on team performance and “Big 5” trait composition. Results demonstrate that teams …

“Arguments Online, But In School We Always Act Normal”: The Embeddedness Of Early Adolescent Negative Peer Interactions Within The Whole Of Their Offline And Online Peer Interactions, Sara Pabian, Sara Erreygers, Heidi Vandebosch, Kathleen Van Royen, Julie Dare, Leesa N. Costello, Lelia Green, Dianne Hawk, Donna S. Cross

Research outputs 2014 to 2021

The goal of the present study was to investigate how negative peer interactions offline and online are associated with each other and with other daily interactions among early adolescents. To this aim, photo-elicitation interviewing was used to gather data among a sample of 34 early adolescents (13–14 years). A thematic analysis revealed that adolescents experience a wide range of different types of negative peer interactions offline and online. Most of the negative interactions recalled by the participants took place exclusively offline or online, and only a few were continued and/or managed in another environment. When participants were involved in online …

The Reciprocal Relationship Between Passive Social Networking Site (Sns) Usage And Users’ Subjective Well-Being, Jin-Liang Wang, James Gaskin, Detlef H. Rost, Douglas A. Gentile

Faculty Publications

Prior studies have found an inconclusive relationship between social networking site (SNS) usage and users’ subjective well-being. Passive SNS usage may be detrimental to subjective well-being, because it cannot provide social support and may evoke envy and jealousy. Conversely, it is also possible that lower subjective well-being may predict higher passive SNS usage, which can be used as a means to relieve stress. To examine this reciprocal process, a two-wave study among a sample of Chinese college students was conducted (N ¼ 350 at Time 1, 265 at Time 2). Data were analyzed with structural modeling. Cross-lagged analysis indicated that …

Successful System Use: It’S Not Just Who You Are, But What You Do, James Eric Gaskin, Stephen Godfrey, Alex Vance

Faculty Publications

Information and communication technologies are so embedded in contemporary society that we have arrived at the point at which learning to use technology successfully may affect our day-to-day lives as much as learning to eat or exercising properly. However, we lack research that explains and predicts successful system use (i.e., system use that adds value to the user). We theorize that adaptive behaviors (e.g., trying new features, repurposing features) mediate the relationship between user characteristics and successful system use. To better understand successful system use, we used an online survey to study how undergraduate students enrolled in an information systems …

Research outputs 2014 to 2021

Results: Twenty-six studies with 51 623 participants (28 314 men, 23 309 women; mean age 51.8 years) met inclusion criteria and were included in this study. Among them, six studies showed a significant association between OSA and resistant hypertension (pooled OR = 2.842, 95% CI = 1.703-3.980, P < 0.05). Meanwhile, the combination of 20 original studies on the association of OSA with essential hypertension also presented significant results with the pooled ORs of 1.184 (95% CI = 1.093-1.274, P < 0.05) for mild OSA, 1.316 (95% CI = 1.197-1.433, P < 0.05) for moderate OSA and 1.561 (95% CI = 1.287-1.835, P < 0.05) for severe OSA.

Conclusions: Our findings indicated that OSA is related to an increased risk of resistant hypertension. Mild, moderate and severe OSA are associated essential hypertension, as well a dose-response manner relationship is manifested. The associations are relatively stronger among Caucasians and male OSA patients.

Background: Obstructive sleep apnea (OSA) is a sleep disorder …

The Protective Effects Of Social Support And Engagement Coping Strategy On The Relationship Between Perceived Discrimination And Psychological Distress Among Chinese Migrant Children, Jin-Liang Wang, Hsing-Fang Hsieh, Shervin Assari, James Gaskin, Detlef H. Rost

Faculty Publications

This study was aimed to figure out whether perceived stress mediates the relationship between perceived discrimination and psychological distress among Chinese migrant children and whether social support and engagement coping moderate the detrimental effects of perceived discrimination on psychological distress. The sample comprised 813 middle-school students (482 migrant children, 331 non-migrant children) from three schools in Southwest China. The results indicate that migrant children’s perceived discrimination and perceived stress are associated with psychological distress, and perceived stress does not mediate the relationship between perceived discrimination and psychological distress. Both social support and engagement coping are inversely related to psychological distress …

Online Student Use Of A Proximate Community Of Engagement In An Independent Study Program, Darin R. Oviatt, Charles R. Graham, Randall S. Davies, Jered Borup

Faculty Publications

Research has suggested that independent study students in online courses may benefit from engaging with a proximate community of engagement (PCE) and that students perceive that such engagement will help them succeed. Independent Study students were surveyed at the completion of their course to assess the level at which they actually interacted with a PCE. Survey findings were confirmed with follow-up interviews with students and their parents to triangulate survey data. Findings revealed that students in the study interacted with a PCE when completing the course. The percentage of students actually engaged with a PCE was lower than the percentages …

Exploring The Potential Of Lms Log Data As A Proxy Measure Of Student Engagement, Curtis R. Henrie, Robert Bodily, Ross Larsen, Charles R. Graham

Faculty Publications

This study examines the relationship between log data of student activity in learning management systems and self-reported student engagement survey scores. Log data has the potential to serve as a meaningful proxy for survey scores. Should this be the case, log data could be used as a minimally disruptive and scalable approach to quickly identify who needs help, evaluate design, and personalize instruction. We correlated LMS log data variables to student engagement survey scores to study the relationship between these two sources of data. Overall, log data was not a statistically significant proxy measure of students’ self-reported cognitive and emotional …

Blended Learning: The New Normal And Emerging Technologies, Charles Dziuban, Charles R. Graham, Patsy D. Moskal, Anders Norberg, Nicole Sicilia

Faculty Publications

This study addressed several outcomes, implications, and possible future directions for blended learning (BL) in higher education in a world where information communication technologies (ICTs) increasingly communicate with each other. In considering effectiveness, the authors contend that BL coalesces around access, success, and students’ perception of their learning environments. Success and withdrawal rates for face-to-face and online courses are compared to those for BL as they interact with minority status. Investigation of student perception about course excellence revealed the existence of robust if-then decision rules for determining how students evaluate their educational experiences. Those rules were independent of course modality, …
