The Burr X Exponentiated Weibull Model: Characterizations, Mathematical Properties And Applications To Failure And Survival Times Data, Mohamed G. Khalil, Gholamhossein G. Hamedani, Haitham M. Yousof

Mathematical and Statistical Science Faculty Research and Publications

In this article, we introduce a new three-parameter lifetime model called the Burr X exponentiated Weibull model. The major justification for the practicality of the new lifetime model is based on the wider use of the exponentiated Weibull and Weibull models. We are motivated to propose this new lifetime model because it exhibits increasing, decreasing, bathtub, J shaped and constant hazard rates. The new lifetime model can be viewed as a mixture of the exponentiated Weibull distribution. It can also be viewed as a suitable model for fitting the right skewed, symmetric, left skewed and unimodal data. We provide a …

Incomplete Gamma Distribution: A New Two Parameter Lifetime Distribution With Survival Regression Model, Aliakbar Rasekhi, Mahdi Rasekhi, Gholamhossein Hamedani

Mathematical and Statistical Science Faculty Research and Publications

We introduce a new two parameter lifetime distribution constructed via incomplete gamma function which includes exponential distribution as a limiting case. This distribution is more flexible than most of the two parameter extended exponential distributions. Various statistical properties such as moments, moment generating function and certain useful characterizations based on the ratio of two truncated moments are presented. Maximum likelihood estimation method is used for estimating parameters of this distribution and a survival regression model based on the proposed distribution is presented for fitting breast cancer data set.

Taking Data, Michael C. Pollack

Articles

Technological development has created new forms of information, altered expectations of privacy, and given law enforcement more tools to examine that information and intrude on that privacy. One crucial facet of these changes involves internet service providers (ISPs): as people expose more of their lives to their ISPs—all the websites they visit, people they communicate with, emails they send, files they store, and more—law enforcement efforts to access that data become more and more common. But scholars and policymakers alike recognize that the existing statutory frameworks governing those efforts are based on obsolete technology and strike balances that are difficult …

This article discusses major changes in the advertising industry, and calls for thought leadership to bridge the gap between academia and the industry and to initiate proactive changes in advertising education.

Identification And Crisis: An Exploration Into The Influence Of Sports Identification On Stakeholder Perceptions Of Sports-Related Crisis, Jennifer L. Harker

Faculty & Staff Scholarship

This research examines sports identification as relational history with sports entities to test its predictive influence on stakeholders’ perceptions regarding sports-related crises. Sports identification was explored as both a social identification with sport (fandom) and as an individual identification with sport (fanship). Results suggest that sports identification is indeed a predictive element to stakeholders’ crisis perceptions; however, findings track in an interesting new direction that extends crisis communication theory in sport and suggests that sports crises are perceived in a similar manner to sports rivalries.

Changing The Story: Implications Of Narrative On Teacher Identity, Geah Pressgrove, Melissa Janoske, Stephanie Madden

Faculty & Staff Scholarship

This study takes a qualitative approach to understanding the connections among narrative, professional identity, and reputation management in public education. Through 15 interviews and five focus groups with high-achieving teachers and administrators, researchers explored the narratives these educators share to understand and improve the story of the teaching profession. Central to the findings are societal, organizational, and community-level factors that have led to a reputation crisis for the profession of teaching and thus contribute to the national teacher shortage. Ultimately, this study points to the notion that a shift in the perception of the value of teaching and teachers can …

Comparing Written Versus Pictorial Asthma Action Plans To Improve Asthma Management And Health Outcomes Among Children And Adolescents: Protocol Of A Pilot And Feasibility Randomized Controlled Trial, Lisa Hynes, Kristine Durkin, Desireé N. Williford, Hope Smith, David Skoner, Christa Lilly, Viral Dilip Kothari, Jenny Mcsharry, Christina L. Duncan

Faculty & Staff Scholarship

Background: Asthma is an important focus for pediatric health research as management of asthma symptoms is a significant challenge, and morbidity and mortality among youths with asthma remain prevalent. Treatment guidelines for asthma recommend a written asthma action plan (WAAP) that summarizes individualized instructions for daily medication use. However, WAAPs are typically written at a seventh- to ninth-grade reading level, which can be a barrier to young people in understanding their treatment, having confidence in using a WAAP, and engaging with asthma education.

Objective: Utilizing a feasibility and pilot randomized controlled trial (RCT) design, the objective of the Take Action …

Can Religiosity Be Explained By ‘Brain Wiring’? An Analysis Of Us Adults’ Opinions, Sharan Kaur Mehta, Christopher P. Scheitle, Elaine Howard Ecklund

Faculty & Staff Scholarship

Studies examining how religion shapes individuals’ attitudes about science have focused heavily on a narrow range of topics, such as evolution. This study expands this literature by looking at how religion influences individuals’ attitudes towards the claim that neuroscience, or “brain wiring,” can explain differences in religiosity. Our analysis of nationally representative survey data shows, perhaps unsurprisingly, that religiosity is negatively associated with thinking that brain wiring can explain religion. Net of religiosity, though, individuals reporting religious experiences are actually more likely to agree that brain wiring can explain religiosity, as are individuals belonging to diverse religious traditions when compared …

Father-Daughter Incest: Comparison Of Treated Cases To Untreated Control Subjects, Keith W. Beard, Jason E. Newsome, Karen V. Harper-Dorton, Stephen L. O'Keefe, Debra H. Young, Sam Swindell, Walter E. Stroupe, Kerri Steele, Megan Lawhon, Shih-Ya Kuo

Faculty & Staff Scholarship

Treatment of father daughter incest (FDI) survivors using the victim advocacy/child welfare approach to FDI that predominates today in the US has never been compared to results in untreated control subjects in any published report. In the present study, thirty-two survivors of FDI who received treatment based on the victim advocacy/child welfare approach to FDI were compared to 32 control subjects who did not receive treatment. No significant differences were found using analysis of variance on 21 scales and subscales. Statistical analysis of the data from all 64 of the FDI survivors showed that items reflecting a poor self-image and …

Effects Of Patch-Burn Grazing On Breeding Density And Territory Size Of Dickcissels, Bram H. F. Verheijen, Hannah L. Clipp, Alessandro J. Bartolo, William E. Jensen, Brett K. Sandercock

Faculty & Staff Scholarship

Ongoing habitat loss and intensification of management of remaining grasslands have led to large population declines of grassland songbirds in North America. As an alternative to intensive and homogeneous use of rangelands, patch-burn grazing creates heterogeneity in vegetative structure across the landscape by restoring the historical interaction of fire and grazing by large ungulates. Patch-burn grazing can increase diversity and abundance of grassland songbirds, but effects on local breeding density and territory size remain unknown, despite both being important in regulating population dynamics of species. Understanding patterns of density and territory size across the landscape is especially important for species …

Protoconch Enlargement In Western Atlantic Turritelline Gastropod Species Following The Closure Of The Central American Seaway, Stephanie Sang, Dana Suzanne Friend, Warren Douglas Allmon, Brendan Matthew Anderson

Faculty & Staff Scholarship

Abstract The closure of the late Neogene interoceanic seaways between the Western Atlantic (WA) and Tropical Eastern Pacific (TEP)—commonly referred to as the Central American Seaway—significantly decreased nutrient supply in the WA compared to the TEP. In marine invertebrates, an increase in parental investment is expected to be selectively favored in nutrient‐poor marine environments as prolonged feeding in the plankton becomes less reliable. Here, we examine turritelline gastropods, which were abundant and diverse across this region during the Neogene and serve as important paleoenvironmental proxies, and test whether species exhibit decreased planktotro‐ phy in the WA postclosure as compared to …

Welcome To The Neighborhood: Communities Of Practice And Identity Development Of Athletic Training Students, Alicia Dionne Champagne

Theses and Dissertations

Clinical education is a large component of athletic training education and is centered on social learning. Students learn how an athletic trainer functions through exposure to a community of practice. As students transition towards full participants in the clinical environment, they get to practice their skills and begin developing their professional identity. As the profession prepares to transition to solely entry-level master’s degrees in 2022, many athletic training programs will need to alter and re-evaluate the clinical experiences available for students. This phenomenological study explored social learning within the clinical environment with an emphasis on how interactions within these communities …

Performance Analysis Of Machine Learning Algorithms In Detecting Cyber Attacks Targeting Automatic Dependent Surveillance-Broadcast (Ads-B) Systems, Mohsen Riahi Manesh

Theses and Dissertations

In order to support air traffic control services, the U.S. Federal Aviation Administration (FAA) has mandated the use of automatic dependent surveillance-broadcast (ADS-B) in aircraft in certain classes of airspace by January 2020. This system aims to replace the legacy approaches, such as primary and secondary radars, by employing global navigation satellite systems for its operation to generate a precise air picture for air traffic management. The major downside of this system is its security as it broadcasts information of an aircraft such as its position and velocity over an unencrypted datalink. This lack of security makes the ADS-B vulnerable …

Relationships Between Sibling Physical Abuse And Lifetime Aggression Using Statistical Controls For Poly-Victimization, Ani Celine Mangold

Theses and Dissertations

Sibling abuse, as a potential contributor to lifetime aggression, is under-represented in the childhood maltreatment literature and minimized in American society. A contemporary survey study conducted using a large college sample (King et al., 2017) established significant relationships between sibling abuse (i.e., acts of physical abuse, threats of violence, and heated verbal conflict) and a range of lifetime aggression indicators after controlling for variance attributable to physical, sexual, intimate partner, and peer abuse. The present study examined sibling physical abuse and established these same relationships using a national sample after controlling for variance due to childhood physical abuse, observed violence …

Consumerism-Driven History: The American Girl Brand As Publisher And Arbiter Of Girlhood Identity, Sarah Loepp

Book Publishing Final Research Papers

American Girl is a highly recognizable brand that wears several hats: publisher, dollmaker, and purported educator. Yet many researchers point out a disconnect between merchandise-driven aspects of the company and its educational qualities, as well as the set of cultural values suggested in material consumption versus the brand literature’s stated representation of girlhood. This paper outlines research pertaining to these issues before engaging in a close reading analysis of one of the historical character’s book series, ascertaining how the aforementioned concepts play out in the text itself. Assessment of American Girl consumption practices further draw from the brand’s website and …

Elementary & Special Education: Faculty Publications

This article provides six fundamental steps for using a task analysis to teach emergent literacy skills to young learners with autism spectrum disorder (ASD). Compared to general education peers, students with ASD score lower on reading measures and often have difficulty acquiring literacy skills via the instruction methods used in typical classrooms. An effective instructional technique for many students with ASD is systematic instruction via task analysis. Task analysis may be a useful tool for teachers of students with ASD to build literacy skills by aligning instruction in missing skills to the curriculum standards. The steps to consider when using …

Relationships Between Hofstede's Cultural Dimensions And Tourist Satisfaction: A Cross-Country Cross-Sample Examination, Songshan (Sam) Huang, John Crotts

Research outputs 2014 to 2021

Culture has been assumed to influence tourist behavior but due to the difficulty of measuring culture values directly at the individual level, the relationship between national culture and visitor satisfaction remains yet to be empirically attested. This study used two national level inbound tourist samples, i.e., Tourism Research Australia's 2017 International Visitor Survey holiday/pleasure travellers’ sample and the Hong Kong Tourist Satisfaction Index Project 2016 sample, to test the relationships between Hofstede's six cultural dimensions (Power Distance, Individualism/Collectivism, Masculinity/Femininity, Uncertainty Avoidance, Long Term Orientation/Short Term Normative Orientation, and Indulgence/Restraint) and visitor satisfaction. Bivariate correlation with bootstrapping tests show consistent correlations …

Nitric oxide (NO) facilitates anti-atherosclerotic effects. Vegetables are a major source of dietary nitrate. Experimental data indicates that dietary nitrate can significantly reduce major risk factors for atherosclerosis and subsequent cardiovascular disease (CVD), as nitrate can be metabolized to produce NO via the nitrate-nitrite-NO pathway. The purpose of this study was to prospectively investigate the association between habitual dietary nitrate intakes and the incidence of self-reported CVD-related complications within a representative sample of middle-aged Australian women (1946–1951 cohort of the Australian Longitudinal Study on Women’s Health). Women free from disease at baseline who had completed the food frequency questionnaire data …

Green-Tinted Glasses: How Do Pro-Environmental Citizens Conceptualize Environmental Sustainability?, Hannah V. Uren, Peta L. Dzidic, Lynne D. Roberts, Zoe Leviston, Brian J. Bishop

Research outputs 2014 to 2021

Recent research has shown that many Australians see pro-environmental behaviour as desirable and identify as being green. However when compared to other countries, Australians score poorly on pro-environmental behaviour measures, engaging mostly in tokenistic pro-environmental actions, and demonstrate low levels of concern for the environment. In this article, we examine this tension through exploring the meaning of the term sustainability to Australian participants who self-identify as pro-environmental. Twenty-six interviews were conducted and analysed using a causal layered analysis. Through the examination of participants’ environmental discourse and practices, some of the deeper socio-psychological processes influencing pro-environmental behaviour are revealed. While participants …

Real-Time Classification Of Multivariate Olfaction Data Using Spiking Neural Networks, Arnup Vanarse, Adam Osseiran, Alexander Rassau, Therese O'Sullivan, Jonny Lo, Amanda Devine

Research outputs 2014 to 2021

Recent studies in bioinspired artificial olfaction, especially those detailing the application of spike-based neuromorphic methods, have led to promising developments towards overcoming the limitations of traditional approaches, such as complexity in handling multivariate data, computational and power requirements, poor accuracy, and substantial delay for processing and classification of odors. Rank-order-based olfactory systems provide an interesting approach for detection of target gases by encoding multi-variate data generated by artificial olfactory systems into temporal signatures. However, the utilization of traditional pattern-matching methods and unpredictable shuffling of spikes in the rank-order impedes the performance of the system. In this paper, we present an …
