Influence Of Substrate Stage Temperature And Rotation Rate On The Magneto-Optical Quality Of Rf-Sputtered Bi2.1dy0.9fe3.9ga1.1o12 Garnet Thin Films, Mohammad E. Alam, Mikhail Vasiliev, Kamal Alameh

Research outputs 2014 to 2021

Highly bismuth-substituted iron garnet thin films are prepared on quartz substrates by using a radio frequency (RF) magnetron sputtering technique. We study the factors (process parameters associated with the RF magnetron sputter deposition technique) affecting the magneto-optical (MO) properties of ferrite garnet films of composition Bi2.1Dy0.9Fe3.9Ga1.1O12. All films show high MO response across the visible range of wavelengths after being annealed. In particular, the effects of substrate stage temperature and rotation rate on the various properties of films are studied. Experimental results reveal that the characteristics of garnet films of this type can be tuned and optimized for use in …

Research outputs 2014 to 2021

Vitamin D deficiency is highly prevalent in newly settled refugees in Western Australia (WA). If adherence to daily vitamin D therapy is problematic, depot therapy is a therapeutic alternative. The aim of this studywas to compare daily versus depot treatment and factors influencing the therapeutic outcome. Newly settled refugees (n = 151) with 25(OH)D levels less than 78 nmol/L were randomised to receive daily or depot vitamin D therapy with eight weekly interval follow up to 40 weeks. Biochemical and clinical parameters were collected at each visit. Generalized LinearMixedModels (GLMM) examined the longitudinal changes over time controlling for confounders including …

The Nexus Of Nursing Leadership And A Culture Of Safer Patient Care, Melanie Murray, Deborah R. Sundin, Vicki C. Cope

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 …

Association Of Obstructive Sleep Apnea With Hypertension: A Systematic Review And Meta-Analysis, Haifeng Hou, Yange Zhao, Xiaotong Xue, Jian Ding, Wei Jia Xing, Wei Wang

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 …

Working With The Enemy? Social Work Education And Men Who Use Intimate Partner Violence, Rebecca Jury, Kathy Boxall

Research outputs 2014 to 2021

This article examines service user involvement in social work education. It discusses the challenges and ethical considerations of involving populations who may previously have been excluded from user involvement initiatives, raising questions about the benefits and challenges of their involvement. The article then provides discussion of an approach to service user involvement in social work education with one of these populations, men who use violence in their intimate relationships, and concludes by considering the implications of their involvement for the social work academy.

Efficiency And Risk In Sustaining China’S Food Production And Security: Evidence From Micro-Level Panel Data Analysis Of Japonica Rice Production, Chengjun Wang, Zhaoyong Zhang, Ximin Fei

Research outputs 2014 to 2021

Sustainable food production and food security are always challenging issues in China. This paper constructs a multi-element two-level constant-elasticity-of-substitution (CES) model to assess technological progress in, and its contribution to, japonica rice production in China. The results show that the speed of technological progress in the production of japonica rice on average was 0.44% per annum in 1985–2013, and technological progress has contributed significantly to the growth of japonica rice production in China. Robustness checks show that the results appear to be sensitive to which sub-sample is used. Labour and some other inputs are found to be significant but negative, …

Grey Wolf Optimization-Based Optimum Energy-Management And Battery-Sizing Method For Grid-Connected Microgrids, Kutaiba Sabah Nimma, Monaaf D. A. Al-Falahi, Hung Duc Nguyen, S. D. G. Jayasinghe, Thair Mahmoud, Michael Negnevitsky

Research outputs 2014 to 2021

In the revolution of green energy development, microgrids with renewable energy sources such as solar, wind and fuel cells are becoming a popular and effective way of controlling and managing these sources. On the other hand, owing to the intermittency and wide range of dynamic responses of renewable energy sources, battery energy-storage systems have become an integral feature of microgrids. Intelligent energy management and battery sizing are essential requirements in the microgrids to ensure the optimal use of the renewable sources and reduce conventional fuel utilization in such complex systems. This paper presents a novel approach to meet these requirements …

Measuring The Prevalence Of Intradialytic Hypotension In A Satellite Dialysis Clinic: Are We Too Complacent?, Ulrich Steinwandel, Nick Gibson, Mandy Towell-Barnard, Richard Parsons, James J. R. Rippey, Johan Rosman

Nitrate, The Oral Microbiome, And Cardiovascular Health: A Systematic Literature Review Of Human And Animal Studies, Lauren C. Blekkenhorst, Nicola P. Bondonno, Alex H. Liu, Natalie C. Ward, Richard L. Prince, Joshua R. Lewis, Amanda Devine, Kevin D. Croft, Jonathan M. Hodgson, Catherine P. Bondonno

Research outputs 2014 to 2021

Background

Dietary nitrate is an important source of nitric oxide (NO), a molecule critical for cardiovascular health. Nitrate is sequentially reduced to NO through an enterosalivary nitrate-nitrite-NO pathway that involves the oral microbiome. This pathway is considered an important adjunct pathway to the classical l-arginine–NO synthase pathway.

Objective

The objective of this study was to systematically assess the evidence for dietary nitrate intake and improved cardiovascular health from both human and animal studies.

Design

A systematic literature search was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by using key search terms in Medline and …

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, …

Faculty Publications

We have designed, developed, and implemented a student-facing learning analytics dashboard in order to support students as they learn in online environments. There are two separate dashboards in our system: a content recommender dashboard and a skills recommender dashboard. The content recommender helps students identify gaps in their content knowledge; the skills recommender helps students improve their metacognitive strategies. We discuss the technical requirements needed to develop a real-time student dashboard as well as report our inquiry into the functionality students want in a dashboard. The dashboards were evaluated with focus groups and a perceptions survey. Students were positive in …

Generic Vs. Modality-Specific Competencies For K-12 Online And Blended Teaching, Emily Pulham, Charles R. Graham, Cecil R. Short

Faculty Publications

Although research has explored teacher competencies in K-12 blended and online learning, it has not specified which competencies are appropriate to an online or digital medium, which refer to blending in-person with online experiences, or which are generic—applicable in any teaching modality. This article explores selected K-12 online and blended teaching competency documents to determine which specific modalities (online, in-person, blended, or generic) the competencies address. Many competencies are still categorized as generic, and not specific enough to denote a particular context. The authors give recommendations for pre-service teacher education and indicate needs for further research in K-12 online and …

Comparing K-12 Online And Blended Teaching Competencies: A Literature Review, Emily Pulham, Charles R. Graham

Faculty Publications

This article presents a synthesis of reports and research on K-12 blended teaching competencies compared with K-12 online teaching competencies. The skills needed to teach in online and blended environments are distinct from traditional teaching, but teacher education programs often do not equip preservice teachers for the new modes of instruction. Additionally, there is a dearth of research on blended teaching competencies. This review synthesizes 8 blended teaching documents and 10 online teaching documents. Seven global themes identified in both competency domains are (1) pedagogy, (2) management, (3) assessment, (4) technology, (5) instructional design, (6) dispositions, and (7) improvement. The …

Controls And Cooperation In Interactive And Non-Interactive Settings, Jace Garrett, Jeffrey A. Livingston, William B. Tayler

Faculty Publications

Prior research finds that controls that induce cooperation among collaborators on a project increase trust, and that this increased trust increases subsequent cooperation among collaborators. We extend this work by investigating how controls influence cooperative behavior in two settings. The first is an interactive setting where people work together and can benefit from each other’s work. The second is a non-interactive setting where people do not work together directly, but where behavior can be observed. We propose that because controls are likely to engender greater trust and reciprocity in interactive settings than in non-interactive settings, the effect of controls on …

Citation-Based Benchmarks And Individual Accounting Faculty Research Rankings By Topical Area And Methodology, Garrison Nuttall, Neal Snow, Scott L. Summers, David A. Wood

Faculty Publications

This paper provides citation rankings and benchmarking data for individual accounting researchers disaggregated by topic and methodological area and studies which factors increase citation totals. Based on Google Scholar data from 7,113 articles published in respected accounting journals, we find that citation totals differ significantly based on accounting topic area (accounting information systems, audit, financial, managerial, tax, other) and methodology (analytical, archival, experimental, other), suggesting the need to separately benchmark authors who publish in these groups. We also find that authors who have a broad collaboration network, graduated from a school that started a journal, are topic specialists, or publish …

Toward Conflict Or Compromise? How Violent Metaphors Polarize Partisan Issue Attitudes, Nathan P. Kalmoe, Joshua R. Gubler, David A. Wood

Faculty Publications

We know much about how opinion leaders drive mass partisan polarization with position-taking cues but little on how different message types polarize citizens, and who responds most to those messages attributes. This article contributes new insights by investigating how exposure to common violent metaphors interacts with audience personality traits to polarize partisans on issues. Building from research on conflict orientations, we theorize that aggressive rhetoric primes aggression in aggressive partisans, motivating greater intransigence on party positions. As a consequence, aggressive partisans are pulled further apart on issues, thereby reducing prospects for compromise. We find support for our predictions in two …

Detecting Discrimination In Small Business Lending, Sterling A. Bone, Glenn L. Christensen, Jerome D. Williams, Stella Adams, Anneliese Lederer, Paul C. Lubin

Faculty Publications

With limited financial sophistication, entrepreneurial consumers approach the financial marketplace more like retail financial consumers than business customers. However, the assumption of both legislators and regulators is that business-borrowers are more financially savvy than consumer-borrowers, and thus do not require as broad-reaching protections. This gap between marketplace policy protections and the lived reality of the vast majority of small business entrepreneurs sets the stage for entrepreneurial consumers to fall through the regulatory cracks and sets the stage for possible exploitation and abuse. This situation is potentially exacerbated for minority entrepreneurs who belong to protected classes that are generally more vulnerable …

Pushing The Future Back: The Impact Of Policy Uncertainty On The Market Pricing Of Future Earnings, Michael S. Drake, Michael A. Mayberry, Jaron H. Wilde

Faculty Publications

We examine whether policy uncertainty triggered by presidential elections pushes the future back by reducing the extent to which current prices reflect information about future earnings. We estimate future earnings response coefficients (FERCs) for the years 1975– 2013, a period that covers ten presidential elections. We find that FERCs are significantly lower (by 11.8%) during presidential election years compared to other years. Additional analyses using pseudo election years, ex-ante polls, contract prices from the Iowa Electronic Political Market, and cross-sectional firm characteristics provide corroborating evidence that the lower FERCs during election years are related to policy uncertainty. We also investigate …

The Humanities: Our Human Journey, Ilona Klein

Faculty Publications

Life. The miracle of human life. Scientists believe that our incarnation as anatomically modern humans–homo sapiens–began on African soil about 200,000 years ago, as we started walking erect on two legs instead of four. We wandered upon our planet, a tiny, beautiful, blueish speck almost literally in the middle of nowhere, traveling elliptically around our sun within the cold, dark immensity of the universe.

Abinadi's Legacy: Tracing His Influence Through The Book Of Mormon, John L. Hilton Iii

Faculty Publications

Eminent author Ralph Waldo Emerson wrote, "All minds quote. Old and new make the warp and woof of every moment. There is no thread that is not a twist of these two strands. By necessity, by proclivity, and by delight, we all quote." Identifying these instances of textual weavings is one aspect of a literary field known as intertextuality, an area that holds great promos for Book of Mormon research. Grant Hardy has suggested that it would be fruitful for our understanding of the Book of Mormon "to track various phrases throughout the Book of Mormon to determine which Nephite …

Violent Video Games, Externalizing Behavior, And Prosocial Behavior: A Five-Year Longitudinal Study During Adolescence, Sarah M. Coyne, Wayne A. Warburton, Lee W. Essig, Laura A. Stockdale

Faculty Publications

Decades of research on the effects of media violence have examined associations between viewing aggressive material in the media and aggression and prosocial behavior. However, the existing longitudinal studies have tended to exclusively examine aggression and prosocial behavior as outcomes, with a limited range of potential mediators. The current study examines associations between playing violent video games and externalizing and prosocial behavior over a 5-year period across adolescence. Additionally, the study examines potential mediators of these associations, including empathic concern, benevolence, and self-regulation. Participants included 488 adolescents (MAge of child at Wave 1 􏰀13.83, SD 􏰀 0.98) and their parents, …

Teaching Children About Money: Prospective Parenting Ideas From Undergraduate Students, Ashley B. Lebaron, Christina M. Rosa-Holyoak, L. Ashley Bryce, E. Jeffrey Hill, Loren D. Marks

Faculty Publications

Many Millennials (aged 18-30 in 2016) are struggling with financial capability and independence. As efforts unfold to address this issue by improving financial education, Millennials themselves can offer helpful family-centered ideas for children 's financial learning. As part of the Whats and Hows of Family Financial $ocialization project, this qualitative study explored the ideas of 126 undergraduate students enrolled in family finance classes at three institutions from three regions of the United States about how and what they intend to teach their future children about finances. Thematic content analysis and coding of interviews revealed four core themes: (a) "Communicating Family …
