Is Your Susceptibility To Phishing Dependent On Your Memory?, Bonnie Brinton Anderson, Anthony Vance, David Eargle

Faculty Publications

Phishing has become a major attack vector for hackers and cost victims $687 million in the first half of 2012 alone. Additionally, despite technical solutions to defend against this threat, reports show that phishing attacks are increasing. There is therefore a pressing need to understand why users continue to fall victim to phishing, and how such attacks can be prevented. In this researchin- progress paper, we argue that the cognitive neuroscience of memory provides a useful lens through which to study the problem of phishing. A commonly reported finding from the field of memory is the eye movement-based memory effect, …

Evaluating Journal Quality And The Association For Information Systems (Ais) Senior Scholars’ Journal Basket Via Bibliometric Measures: Do Expert Journal Assessments Add Value?, Paul Benjamin Lowry, Gregory D. Moody, James Gaskin, Dennis F. Galletta, Sean L. Humpherys, Jordan B. Barlow, David W. Wilson

Faculty Publications

Information systems (IS) journal rankings and ratings help scholars focus their publishing efforts and are widely used surrogates for judging the quality of research. Over the years, numerous approaches have been used to rank IS journals, approaches such as citation metrics, school lists, acceptance rates, and expert assessments. However, the results of these approaches often conflict due to a host of validity concerns. In the current scientometric study, we make significant strides toward correcting for these limitations in the ranking of mainstream IS journals. We compare expert rankings to bibliometric measures such as the ISI Impact Factor™, the h-index, and …

Taking “Fun And Games” Seriously: Proposing The Hedonic-Motivation System Adoption Model (Hmsam), Paul Benjamin Lowry, Bryan Hammer, James Eric Gaskin, Tom L. Roberts, Nathan W. Twyman

Faculty Publications

Hedonic-motivation systems (HMS)—systems used primarily to fulfill users’ intrinsic motivations—are the elephant in the room for IS research. Growth in HMS sales has outperformed utilitarian-motivation systems (UMS) sales for more than a decade, generating billions in revenue annually; yet IS research focuses mostly on UMS. In this study, we explain the role of intrinsic motivations in systems use and propose the hedonic-motivation system adoption model (HMSAM) to improve the understanding of HMS adoption. Instead of a minor, general TAM extension, HMSAM is an HMS-specific system acceptance model based on an alternative theoretical perspective, which is in turn grounded in flow-based …

The Nature Of Adolescent Learner Interaction In A Virtual High School Setting, J. Borup, Charles R. Graham, R.S. Davies

Faculty Publications

This study used survey data to measure the effect of learners’ reported interactions with content, peers, and instructors on several course outcomes in two virtual high school courses that emphasized interactive learning. Surveys found that the large majority of students viewed all investigated types of interaction as educational and motivational. Students perceived learner–instructor and learner–content interactions to have significantly higher educational value (a < 0.01) than learner–learner interactions, and viewed learner–instructor interaction to be significantly more motivational (a < 0.01) than learner–content interaction. Furthermore, nine significant correlations were found involving the time students reported spending on human interaction and course outcomes. Seven of the significant correlations were related to the time students reported spending in human interaction and the more affective outcomes, such as course satisfaction and disposition towards the subject area. Outcomes also indicate that learner–learner interaction had higher correlations with course outcomes than learners’ interactions with the content or their instructor. Students’ perceived learning was not significantly correlated with any type of interaction, and only students’ total reported time spent on learner– learner interaction and students’ social learner–learner interaction were significantly correlated with their grade.

A Framework For Institutional Adoption And Implementation Of Blended Learning In Higher Education, Charles R. Graham, Wendy Woodfield, J. Buckley Harrison

Faculty Publications

There has been rapid growth in blended learning implementation and research focused on course-level issues such as improved learning outcomes, but very limited research focused on institutional policy and adoption issues. More institutional-level blended learning research is needed to guide institutions of higher education in strategically adopting and implementing blended learning on campus. This research investigates six cases of institutional adoption of blended learning to examine the key issues that can guide university administrators interested in this endeavor. Cases were selected to represent institutions at various stages of blended learning adoption including (1) awareness/exploration, (2) adoption/early implementation, and (3) mature …

Towards An Understanding Of The Role Of Standard Setters In Standard Setting, Abigail Allen, Karthik Ramanna

Faculty Publications

We investigate the effect of standard setters in standard setting. We examine how  certain professional and political characteristics of FASB members and SEC commissioners predict the accounting ‘‘reliability’’ and ‘‘relevance’’ of proposed standards. Notably, we find FASB members with backgrounds in financial services are more likely to propose standards that decrease ‘‘reliability’’ and increase ‘‘relevance,’’ partly due to their tendency to propose fair-value methods. We find opposite results for FASB members affiliated with the Democratic Party, although only when excluding financial services background as an independent variable. Jackknife procedures show that results are robust to omitting any individual standard setter.

The Nature Of Parental Interactions In An Online Charter School, Jered Borup, Charles R. Graham, Randall S. Davies

Faculty Publications

A belief commonly held in the K–12 education community is that parents can have a positive impact on their child’s learning. However, little research has examined parental involvement in an online learning environment. In this study, researchers using survey data found that generally students and parents viewed parent–instructor and learner–parent interactions as motivational. Students viewed learner–parent interaction as significantly more motivational than did their parents. The quantity of reported parental interactions was generally negatively correlated with course outcomes. These negative correlations may be the result of parents’ tendency to increase interaction levels following poor student performance and may not reflect …

An Analysis Of Research Trends In Dissertations And Theses Studying Blended Learning, Jeffrey S. Drysdale, Charles R. Graham, Kristian J. Spring, Lisa R. Halverson

A summary of trends regarding the growth and context of blended learning research is presented. Methodological trends are described in terms of qualitative, inferential statistics, descriptive statistics, and combined approaches to data analysis. Research topics are divided into nine topics (learner outcomes, dispositions, instructional design, interaction, comparison, demographics, technology, professional development, and other), each containing several sub-topics. Patterns in these topics are analyzed to identify gaps in research and to highlight opportunities for future research as the field of blended learning continues …

The Influence Of Asynchronous Video Communication On Learner Social Presence: A Narrative Analysis Of Four Cases, Jered Borup, Richard E. West, Charles R. Graham

Faculty Publications

Online courses are increasingly using asynchronous video communication. However, little is known about how asynchronous video communication influences students’ communication patterns. This study presents four narratives of students with varying characteristics who engaged in asynchronous video communication. The extrovert valued the efficiency of making video comments but saw little value in viewing the video comments of her peers. Somewhat inversely, the English language learner valued the video comments of her peers but lacked the ability to fully participate herself. The introverted student valued the flexibility and richness of asynchronous video but spent an inordinate amount of time recording her videos. …

Acquirer Valuation And Acquisition Decisions: Identifying Mispricing Using Short Interest, Itzhak Ben-David, Michael S. Drake, Darren T. Roulstone

Faculty Publications

We use short interest as an investor-based measure of over/undervaluation that distinguishes between the misvaluation and Q-theories of mergers. Using this measure, we find that misvaluation is a strong determinant of merger decision making. Firms in the top quintile of short interest are 54% more likely to engage in stock acquisitions and 22% less likely to engage in cash acquisitions. Stock (but not cash) acquirers have higher short interest than their targets. Overall, our results suggest that the previously documented underperformance of stock acquirers and the overperformance of cash acquirers can be explained by misvaluation, as captured by short interest.

“I Will Bless The Lord At All Times”: Blessing God In The Old Testament, Dana M. Pike

Faculty Publications

Because of his love for them, God is disposed to bless all his children to some extent (see Matthew 5:45). However, in addition to God’s graciously bestowed blessings on all people, many divine blessings are primarily relationship dependent; that is, existing in a particular relationship with God allows one to obtain certain blessings that are often greater than those bestowed upon someone outside such a relationship.1 The Bible indicates that by his power God blessed Adam and Eve (Gen 1:22, 28) and their faithful descendants, including Noah, Abraham, Sarah, and many others. For example, after Noah’s family left their ark, …

My Worst Ever Night At The Best School Ball Ever : Creating Taboo Theatre For Teenagers, Jeremy F. Rice

Theses: Doctorates and Masters

My Worst Ever Night at the Best School Ball Ever (School Ball) is a new play for teenage audiences. The action takes place on the night of a ball for final year students. A prank with a goat goes horribly wrong, a photo of a girl pissing in a pot plant is widely circulated, and everyone finds out about the boy in a sexual relationship with a teacher. At the heart of the play are teenagers, armed with mobile phones, trying to find their way in a contradictory and confusing world.

The creative development of School Ball centred on practice-based …

Silver (Ag) Nanoparticle Based Masks For The Development Of Antireflection Subwavelength Structures In Gaas And Si Solar Cells, Nazme A. Moushumy

Theses: Doctorates and Masters

This thesis focuses on the design and development of silver nanoparticles that can be used as masks for the development of antireflection subwavelength grating (SWG) structures. We particularly investigate the impact of silver thin film thickness and the effect of annealing temperature on the fabrication of silver nanoparticles of controlled size and spacing distributions. We also use these measured distributions to predict the performance of subwavelength grating structures developed using dry and isotropic etching of semiconductor substrates.

Silver (Ag) thin films of different thicknesses are deposited on Silicon (Si) and Gallium Arsenide (GaAs) semiconductor substrates and annealed at different temperatures. …

A Model Of Management Learning For Occupational Therapists In Small Business In Australia, Jeannine Millsteed

Theses: Doctorates and Masters

This research sought to identify factors that contribute to occupational therapists developing management competencies when they become small business owners providing professional clinical services. This is an important for several reasons and precipitated by the Australian government’s introduction of incentives that encourage health professions to move from employment in public hospitals into the private sector, coupled with a recognition that occupational therapists receive no formal business training in their professional education, and the reported high levels of business failure in the small business sector. A review of the literature established the value of small business to the Australian economy, growth …

Biomarkers Of Disease : Concentrations In The Serum Of Women During Natural And Stimulated Ovarian Cycles And During Early Pregnancy, Melissa Stemp

Theses: Doctorates and Masters

Molecular biomarkers are chemical signatures that all cell types possess. They are used in medicine to evaluate both normal biological events and pathogenic processes. A series of biomarkers associated with cancer of the breast, ovaries and other parts of the female reproductive tract and the monitoring of pregnancy were measured in disease‐free women. The biomarkers measured were prostate specific antigen (PSA), CA125, CA15‐3, CA72‐4, and pregnancy associated plasma protein‐a (PAPP‐A). The patterns of change during natural and stimulated ovarian cycles and early pregnancy were investigated to determine if these biomarkers could reflect normal events relating to ovulation and implantation/placentation. In …

Orientocreadium Batrachoides Tubangui, 1931 (Orientocreadiidae): The Only Trematode Parasite Of Clarias Gariepinus (Burchell, 1822) (Clariidae) From The Asi River (Southern Turkey), Tayha Tepe, Mehmet Cemal Oğuz, Mark C. Belk, Remzi Özgen

Faculty Publications

Objective: Some information is available about the parasite fauna and incidence for Clarias gariepinus in Turkey, but digenean parasites have received little attention. The purpose of the study is to contribute to the parasite fauna of Turkey.

Methods: From 2007 to 2008, a total 63 Clarias gariepinus that were caught in the Asi River were purchased from the fish market in Hatay and brought on ice to the Parasitology Research Laboratory at Atatürk University. The fish were dissected. The obtained parasites were fixed with AFA, dyed with Mayer’s Carmalum, and mounted with Canada Balsam.

Results: Forty-eight fish were infected with …

Managers’ Discretionary Adjustments: The Influence Of Uncontrollable Events And Compensation Interdependence, Jasmijn C. Bol, Gary Hecht, Steven D. Smith

Faculty Publications

Discretionary bonus adjustments allow managers to restore the alignment of employee effort and compensation when bonus amounts are based on noisy objective performance measures. The implications of discretionary adjustments for employees' future efforts and fairness perceptions present important trade-offs for managers to consider. Adjustments may be used to motivate different types of effort in future periods, but may also create perceptions of unfairness among employees who are not affected by negative events. This study examines the joint influence of the likelihood of future negative uncontrollable events and compensation interdependence (i.e., the extent to which one employee's compensation influences others' compensation) …

Exploring The Role Delaware Plays As A Domestic Tax Haven, Scott D. Dyreng, Bradley P. Lindsey, Jacob Thornock

Faculty Publications

We examine whether Delaware is a domestic tax haven. We find that taxes play an economically important role in determining whether U.S. firms locate subsidiaries in Delaware and that a Delaware-based state tax avoidance strategy lowers state effective tax rates by between 0.7 and 1.1 percentage points, on average. The tax savings represent a 15–24% decrease in the state income tax burden and translate to an increase in net income of 1.04–1.47%. However, we find that the tax benefits of Delaware tax strategies are diminishing over time in response to initiatives by state governments to limit multistate tax avoidance.

The Effects Of Dividend Taxation On Short Selling And Market Quality, Jacob Thornock

Faculty Publications

This study examines the effects of dividend taxation on the primary parties involved in a short sale: the lender of the stock and the short seller. For stock lenders, dividend taxation is associated with a decrease in the supply of shortable shares and an increase in equity lending fees around the dividend record date. For short sellers, potential reimbursement costs are associated with a significant decrease in short volume before the ex-dividend date followed by a significant increase after the ex-date. Prior research shows that short selling improves price efficiency and formation. Hence, because of the negative effects of taxation …

Urban American Indians: A Comparison Of Father Involvement Predictors Across Race, Jonathan Padilla, Peter Ward, Gordon E. Limb

Faculty Publications

Father involvement in families of urban American Indians has been a neglected area of research. In this study, the authors examined the associations among parental relationship quality, father involvement, and coresidence. The authors conducted a multiple group analysis through structural equation modeling comparing 107 American Indian fathers with fathers of the general population in the Fragile Families and Child Wellbeing Study. Although the results were similar between groups, findings indicated two key differences for urban American Indians. First, emotional supportiveness had a stronger relationship with physically active engagement for American Indian fathers. Second, parental relationship quality had greater total standardized …

Neuromuscular Fatigue And Biomechanical Alterations During High-Intensity, Constant-Load Cycling, Amanda Julie Overton

Theses: Doctorates and Masters

Neuromuscular fatigue is an inevitable process at play during prolonged exercise, and may be caused by multiple alterations within the central nervous system and peripheral musculature. As fatigue develops, the neuromuscular system must adapt to these changes by making compensatory movement pattern adjustments so as to use motor pathways that are less fatigued in an effort to maintain task performance; motor variability is thus increased. The primary purpose of the four studies contained within this doctoral thesis was to detail the progression of exercise-induced neuromuscular fatigue, and to improve our understanding of the muscle activation and joint kinematic alterations that …

Representation And Symbolic Politics In Indonesia : An Analysis Of Billboard Advertising In The Legislative Assembly Elections Of 2009, Eva Leiliyanti

Theses: Doctorates and Masters

The overarching characteristic of the 2009 legislative elections lay in the legislative candidates’ politics of image. It stemmed from the amendment to the election Law no. 10/2008 article 214 that ostensibly cut off the parties’ power in determining their candidates without the public’s “direct” consent. The public was then given a direct opportunity to choose and vote for their preferred candidates in the 2009 elections. This marked the emergence and proliferation of the candidates’ image construction, especially in the “outdoor” political arena. Billboards were chosen as the most effective outdoor advertising medium to introduce the candidates and propagate their slogans …

Pictures In Words : Indexing, Folksonomy And Representation Of Subject Content In Historic Photographs, Brian Stewart

Theses: Doctorates and Masters

Subject access to images is a major issue for image collections. Research is needed to understand how indexing and tagging contribute to make the subjects of historic photographs accessible.

This thesis firstly investigates the evidence of cognitive dissonance between indexers and users in the way they attribute subjects to historic photographs, and, secondly, how indexers and users might work together to enhance subject description. It analyses how current indexing and social tagging represent the subject content of historic photographs. It also suggests a practical way indexers can work with taggers to deal with the classic problem of resource constraints and …

Exercise As Medicine : Reversing Treatment Toxicities In Prostate Cancer Patients, Bradley A. Wall

Theses: Doctorates and Masters

A common treatment for prostate cancer, which is the most common form of cancer after skin cancer in Australian males, is androgen deprivation therapy (ADT). However, ADT is associated with an array of adverse effects including reduced bone and lean mass, loss of muscle strength, negative change in lipid profile, and increased risk of cardiovascular disease (CVD) as well as diabetes, all of which can compromise physical function and quality of life. Physical exercise has been suggested as a key lifestyle intervention for this group of cancer patients as it has enormous potential to limit and even reverse the effects …
