Faculty Publications

This study evaluated the Every Kid in a Park program to understand recreation and the contextual interaction between family resources, race, and recreation costs in families with young children. Using a large, nationally representative data sample from the American Time Use Survey (N = 5,119), we analyzed changes over time in recreation patterns of different socioeconomic groups before and after the initiation of the Every Kid in a Park program of the United States National Park Service. We found that free admission corresponded with overall increased frequency of hiking with a child for individuals in affected households. Changes in hiking …

Where Have All The Children Gone? A Review Of The Presence Of Children Under 6 Years In Leisure Publication Outlets, Rachel A. Mcgovern, Ericka J. Olschewski, Camilla Hodge

Faculty Publications

We conducted a focused search of nine pre-determined leisure journals to (1) determine the prevalence and scope of research on children younger than 6 years (i.e., young children) published in leisure- focused outlets, (2) describe study designs and research methods used to study this age group, (3) tabulate definitions of child leisure, and (4) provide an overview of the studies’ findings. Overall, findings indicate a marked absence of young children from leisure research. Only 28 articles in almost half a century of leisure journal publications met inclusion criteria. Eight studies focused on children as the subject or participant, five articles …

Ecology Of Family Experiences: Contextualizing Family Leisure For Human Development & Family Relations, Camilla Hodge, Kelly D. Chandler, Karen K. Melton, Kelly L. Hoke, Jennifer Blodgett

Faculty Publications

Research on family communication in the leisure context has been limited to retrospective survey reconstructions of perceptions of communication patterns. This study examines the validity of sociometric badges for measuring family communication in real-time. Seven families (married, two-parent families with at least one child ages 4–17 years) wore sociometric badges during a 30-minute leisure activity in a lab setting. We compared mean badge estimates of family communication duration to mean coded video data from the same 30-minute sessions. Intraclass correlation coefficients indicated sociometric badges are not as reliable as video-coded estimates of speech; however, among parents, non-significant mean comparisons partially …

Experience Design In Leisure And Recreation Curriculum, Madie Neeley, Sydney Burgess, Mat D. Duerden, Neil Lundberg

Faculty Publications

Experience design is a term that has risen to the forefront in a variety of professional fields and has relevance for the field of park and recreation. Park and recreation professionals are primarily focused on providing experiences and thus could naturally consider themselves experienced designers. Surprisingly, experience design is not a topic often discussed within park and recreation publications or curriculum. This absence is at least in part attributable to the fact that experience design is an emerging field that has grown independently out of multiple disciplines. Consequently, the fields of park and recreation and experience design overlap in a …

Experience Journey Map: A New Experience Design Tool For Structuring Youth Activities, Gary D. Ellis, Jingxian Jiang, Darlene Locke, Patti A. Freeman, Kaylee Jorgensen

Faculty Publications

We introduce a new experience design tool, an experience journey map, to assist youth professionals in planning engagement, immersion, and absorption activities. Experience journey maps are based on customer journey maps, which are widely used in business service design. This new approach highlights strategies for engendering deep structured experiences during the activity. An experience journey map is a matrix of columns and rows. Columns represent the sequence of activity stages. Rows are experience-structuring strategies derived from the theory of structured experience. These strategies include service performance strategies, deep structured experience strategies, and engagement, immersion, and absorption strategies. We present a …

Differentially Private Fractional Frequency Moments Estimation With Polylogarithmic Space, Lun Wang, Iosif Pinelis, Dawn Song

Michigan Tech Publications, Part 1

We prove that Fp sketch, a well-celebrated streaming algorithm for frequency moments estimation, is differentially private as is when p ∈ (0, 1]. Fp sketch uses only polylogarithmic space, exponentially better than existing DP baselines and only worse than the optimal non-private baseline by a logarithmic factor. The evaluation shows that Fp sketch can achieve reasonable accuracy with differential privacy guarantee. The evaluation code is included in the supplementary material.

Back From The Future: Mediation And Prediction Of Events Uncertainty Through Event-Driven Models (Edms), Samuel Ogbeibu, James Gaskin

Faculty Publications

The event-driven model (EDM) is an emerging concept in human behavioural research, and understanding how EDMs can promote theory development remains a fundamental quest of predictive science. Traditionally, researchers have heavily depended upon theory confirmation and the inclusion of mediating constructs to clarify uncertainty associated with plausible events (e.g. political, socio-economic, technological, environmental). Though this approach has pushed the field forward, it has also steered mediation research towards largely ignoring the fundamental role of prediction as a key for better understanding future events represented by EDMs. Additionally, emerging research using partial least squares structural equation modelling to execute prediction-oriented analysis …

Transformational It Leaders And Digital Innovation: The Moderating Effect Of Formal It Governance, Linda M. Pittenger, Nicholas Berente, James Gaskin

Faculty Publications

Does formal IT governance encourage innovation in the traditional domains of the IT function at the expense of new forms of “digital” innovation? We report on a study of 158 IT managers and leaders to understand the conditions under which transformational IT leadership can drive innovation in traditional forms of IT, as well as in the emerging “digital” domain. We find that highly formal IT governance practices can reduce ability of transformational IT managers and leaders to innovate in both domains, and this effect is greater for digital innovation. In stable cultures the moderation effect was strengthened, while insignificant in …

Digital Behavioral Biometrics And Privacy: Methods For Improving Business Processes Without Compromising Customer Privacy, Joseph S. Valacich, Jeffrey L. Jenkins, D. Čišić

Faculty Publications

To enable people to interact with online websites and systems, browsers capture a variety of events that occur on the page—such as how a person is moving the computer mouse, what a person clicks on, what a person types, and whether a person is scrolling. These events represent a user’s behavior on a page, referred to as the DOM or Document Object Model, and are recorded at a millisecond precision rate (e.g., the exact millisecond timestamp when a key goes down and when it comes back up). Research and practice alike have found that these behavioral events can provide powerful …

The Path Of The Righteous: Using Trace Data To Understand Fraud Decisions In Real Time, Markus Weinmann, Joe Valacich, Christoph Schneider, Jeffrey Jenkins, Martin Hibbeln

Faculty Publications

Trace data—users’ digital records when interacting with technology—can reveal their cognitive dynamics when making decisions on websites in real time. Here, we present a trace-data method—analyzing movements captured via a computer mouse—to assess potential fraud when filling out an online form. In contrast to incumbent fraud-detection methods, which analyze information after submission, mouse-movements traces can capture the cognitive dynamics of a decision to be fraudulent as it is happening. We report two controlled studies using different tasks, where participants could freely commit fraud to benefit themselves financially while we captured mouse-cursor movement data. We found that participants who entered fraudulent …

Prediabetes: Provider Awareness And The Implementation Of The Prevent Diabetes Stat Toolkit Resources, Brooke Feltman

Nursing

Increased proactivity and improved management of prediabetes is a growing need amongst providers in the primary care setting. Nearly one third of North Dakota residents over the age of 20 have prediabetes, but only one out of ten are aware of this reversible medical condition. Without early correction and identification, 15-30% of people with prediabetes will develop type 2 diabetes. Based on the need for increased proactivity towards prediabetic management, evidence-based resources were created by the Centers for Disease Control and Prevention and the American Medical Association. The Prevent Diabetes STAT Toolkit was developed to guide medical professionals in assisting …

Providing Postpartum Depression Resources At A Local Wic Agency, Katie Marie Casey

Nursing

Postpartum depression (PPD) is a significant mental illness that impacts 12.5% of all postpartum women. In women with low-income, the prevalence increases to 25% and 40-60% of low-income, adolescent mothers report depressive symptoms. Postpartum depression also presents a significant early risk to healthy child development and the bond between mother and child. Symptoms of PPD can present as soon as 2 weeks postpartum and as late as 3 years postpartum. Unfortunately, once delivered, women are typically not assessed by a medical provider until 6 weeks postpartum. Therefore, targeting additional opportunities for PPD education in low-income women may play a role …

A Self-Help Intervention For Caregivers Of People Diagnosed With An Eating Disorder, Steven Lin Condon

Nursing

The purpose of this evidence-based practice project was to support caregivers of patients with eating disorders by delivering an evidence-based intervention designed to decrease caregiving burden and illness maintaining behaviors at a regional eating disorder and weight management center (EDWMC). Based on the Cognitive Interpersonal Maintenance Model, the intervention developed by Treasure and colleagues (2006) was shown to improve caregivers’ sense of self-efficacy, interaction with their loved ones, and their loved ones’ outcomes. After receiving the training materials, caregivers of previous studies reported decreases in caregiving burden and illness maintaining behaviors. Furthermore, patients with caregivers who received the intervention also …

Adolescent Mental Health: A Community Needs Assessment, Michael Hammer

Nursing

Depression among adolescents has been trending upward with approximately 3.2 million adolescents aged 12-17 having at least one major depressive episode in the United States (U.S.) in 2016. The incidence of depression also rises with age among adolescents, with depressive episodes at 4.8% for 12-year-olds, 11.8% for 14-year-olds, and as high as 18.5% in adolescents aged 17 years. Interventions aimed at understanding mental health needs of adolescents and reducing barriers to care are essential to improve overall health outcomes for this population. The goal of this community needs assessment was to better understand adolescent mental health and determine the needs …

Incorporating High-Fidelity Aerostructural Analyses In Wind Turbine Rotor Optimization, Denis-Gabriel Caprace, Adam Cardoza, Andrew Ning, Marco Mangano, Sicheng He, Joaquim R. R. A. Martins

Faculty Publications

s demand grows for wind turbines with larger blades, the design of future wind turbines must account for multi-physical interactions and an ever-increasing number of design load conditions. One aspect, aerostructural coupling, calls for design tools that are both accurate and computationally efficient. In this paper, we present a combined-fidelity approach that couples high-fidelity computational fluid dynamics and computational solid mechanics simulations, with a conventional aeroelastic turbine modeling tool based on blade element momentum and beam theories. The approach is integrated into a multidisciplinary optimization framework. It takes advantage of the high-fidelity tightly-coupled aerostructural simulations to evaluate the rotor power …

A General Coupling Methodology For Unsteady Aerostructural Optimization With Analytic Derivatives, Taylor Mcdonnell, Adam Cardoza, Denis-Gabriel Caprace, Andrew Ning

Faculty Publications

Multidisciplinary design optimization offers a comprehensive approach for designing complex aerostructural systems such as wind turbines. Gradient-based multidisciplinary design optimization can be used to optimize complex systems using large numbers of design variables. However, the convergence of gradient-based optimization methods to an optimal solution is highly dependent on the accuracy of the provided derivatives. In this paper, we propose a general method for creating unsteady coupled systems for steady-state, eigenvalue, and time-domain analyses. We then describe how highly accurate derivatives may be obtained from these analyses using a combination of automatic differentiation and analytic methods (including the unsteady adjoint). Finally, …

New Touch Park, Abdirahman Mohamud

Landscape Architecture Theses

My study is to answer the question how can landscapes themselves be interactive, could they be learning & teaching experiences? Can you learn actively from design? Could a landscape teach you a story of a people or a lesson? Are their existing sites that do these things already that we can learn from them? Could it be replicated? What are their structures and programing that make them successful? My study is also promoting and proposing an environment for learning objectives for young developing children in low income housing, with project elements such as natural playground setting, pushing a narrative of …

The Impact Of Skeletal Muscle Disuse On Distinct Echo Intensity Bands: A Retrospective Analysis, Zachary S. Logeson, Rob J. Maclennan, Gerard Kyle B. Abad, Johnathon M. Methven, Molly R. Gradl, Matheus D. Pinto, Ronei S. Pinto, Matt S. Stock

Research outputs 2022 to 2026

Echo intensity (EI) is a novel tool for assessing muscle quality. EI has traditionally been reported as the mean of the pixel histogram, with 0 and 255 arbitrary units (A.U.) representing excellent and poor muscle quality, respectively. Recent work conducted in youth and younger and older adults suggested that analyzing specific EI bands, rather than the mean, may provide unique insights into the effectiveness of exercise and rehabilitation interventions. As our previous work showed deterioration of muscle quality after knee joint immobilization, we sought to investigate whether the increase in EI following disuse was limited to specific EI bands. Thirteen …

Openness About Sexual Orientation And Exposure To Workplace Bullying, Helge Hoel, Duncan Lewis, Anna Einarsdottir, Guy Notelaers

Research outputs 2022 to 2026

Previous studies of workplace bullying have not investigated whether Lesbian, Gay and Bisexual (LGB) employees experience bullying in similar or different ways to their heterosexual counterparts. This study reports on how and to what extent sexuality or sexual orientation influences the experience of workplace bullying and whether openness about sexual orientation elevates risks and shapes exposure to bullying. Using a large and rigorously compiled sample of the British working population comprising 500 non-heterosexuals and 722 heterosexuals (N = 1,222) and applying latent Class Cluster Analysis, a similar behavioural pattern of bullying for LGB employees emerged as for heterosexuals, although LGB …

Finding Geodesics Joining Given Points, Lyle Noakes, Erchuan Zhang

Research outputs 2022 to 2026

Finding a geodesic joining two given points in a complete path-connected Riemannian manifold requires much more effort than determining a geodesic from initial data. This is because it is much harder to solve boundary value problems than initial value problems. Shooting methods attempt to solve boundary value problems by solving a sequence of initial value problems, and usually need a good initial guess to succeed. The present paper finds a geodesic γ: [0 , 1] → M on the Riemannian manifold M with γ(0) = x0 and γ(1) = x1 by dividing the interval [0,1] into several sub-intervals, preferably just …

Physical Layer Authentication Using Ensemble Learning Technique In Wireless Communications, Muhammad Waqas, Shehr Bano, Fatima Hassan, Shanshan Tu, Ghulam Abbas, Ziaul Haq Abbas

Research outputs 2022 to 2026

Cyber-physical wireless systems have surfaced as an important data communication and networking research area. It is an emerging discipline that allows effective monitoring and efficient real-time communication between the cyber and physical worlds by embedding computer software and integrating communication and networking technologies. Due to their high reliability, sensitivity and connectivity, their security requirements are more comparable to the Internet as they are prone to various security threats such as eavesdropping, spoofing, botnets, man-in-the-middle attack, denial of service (DoS) and distributed denial of service (DDoS) and impersonation. Existing methods use physical layer authentication (PLA), the most promising solution to detect …

Relationships Between Intrauterine Fetal Growth Trajectories And Markers Of Adiposity And Inflammation In Young Adults, Ashish Yadav, Lawrence J. Beilin, Rae Chi Huang, Phil Vlaskovsky, John P. Newnham, Scott W. White, Trevor A. Mori

Research outputs 2022 to 2026

Background: There is now good evidence that events during gestation significantly influence the developmental well-being of an individual in later life. This study aimed to investigate the relationships between intrauterine growth trajectories determined by serial ultrasound and subsequent markers of adiposity and inflammation in the 27-year-old adult offspring from the Raine Study, an Australian longitudinal pregnancy cohort. Methods: Ultrasound fetal biometric measurements including abdominal circumference (AC), femur length (FL), and head circumference (HC) from 1333 mother-fetal pairs (Gen1–Gen2) in the Raine Study were used to develop fetal growth trajectories using group-based trajectory modeling. Linear mixed modeling investigated the relationship between …
