Testing Emotion Regulation As A Functional Transdiagnostic Construct, Enoch Sackey

Electronic Theses and Dissertations

The polythetic criteria of the DSM and ICD generate high amount of symptom heterogeneity as there are clusters of symptoms within various diagnostic category that are heuristically similar, resulting in multiple, often confusing, ways of describing sequelae of symptoms presentation. This is because the DSM and ICD classification systems were developed based on the neo-Kraepelinian framework for classifying physical illnesses, which assumes that the underlying architecture of psychopathology, which manifest in disorder symptoms, are distinct and specific. Based on this, the categorical approach to describing psychopathology has been described as purely conceptual artefact with no empirical basis in research or …

Effect Of Excipients/Solvents On The Barrier Integrity And Topical Drug Delivery Across Micropores, Abhishek Shettar

Electronic Theses and Dissertations

The topical and transdermal drug delivery system offers several advantages over conventional drug delivery; non-invasive, patient compliance, avoidance of first-pass metabolism, and sustaining therapeutic drug levels for several days. As a route for drug administration, skin presents a large surface area and can be used for both local and systemic drug delivery. However, the skin forms a formidable barrier protecting the human body from external environmental rigors and excessive water loss, maintaining equilibrium. The skin's barrier properties can be attributed to its unique macromolecular organization and morphology. However, the organized structure of the skin, since intended to prevent the entry …

Optimizing Exposure For Contamination Ocd: What Happens When Digust Is Specifically Targeted?, Molly E. Wickenhauser

Electronic Theses and Dissertations

Disgust is a basic emotion with distinct subjective, physiological, cognitive, and behavioral processes that include revulsion, parasympathetic nervous system activity, contamination-specific appraisals, and disease-avoidance behaviors. Pathological disgust responses may contribute to the development and maintenance of anxiety-related psychopathology, particularly spider and blood-injection-injury phobias, health anxiety, post-traumatic stress disorder, and obsessive-compulsive disorder (OCD). Evidence-based treatments for these disorders were developed based on theories of fear and anxiety and involve exposure-based cognitive-behavior therapy. However, traditional exposure methods appear to be less effective at achieving habituation to disgust compared to fear and anxiety. Additionally, individuals with elevated disgust and primary contagion concerns seem …

Post-Newtonian Dynamics Of Eccentric, Spinning Binary Black Holes And The Associated Gravitational Waveforms, Sashwat Tanay

Electronic Theses and Dissertations

In 2015, the gravitational wave (GW) era of astronomy began. The binary black hole (BBH) system being the primary source of GWs, are at the center stage of GW astronomy. The matched-filtering method of detection of GWs requires accurate modeling of the BBH system and the associated GWs. With the increasing sensitivity of the GW detectors, we need to push our GW models to even higher accuracy in the future. There is also a need to make these models as fast as possible to implement so as to allow for hundreds of detections in a year. This is where the …

Valuing The Public Benefits Of Green Roofs, Noelwah R. Netusil, Sahan Dissanayake, Lauren Lavelle, Amy W. Ando

Economics Faculty Publications and Presentations

Green roofs are being incorporated into stormwater management programs around the world. While numerous studies have estimated the private benefits to the owners and residents of buildings with green roofs, the value of the multiple public benefits received by non-building residents are less well known. We use a choice experiment survey to estimate the public benefits for a proposed green roof program in Portland, Oregon, USA. These benefits include reduced combined sewer overflows, reduced urban heat island effects, and an increase in pollinators such as birds, bees and butterflies. Past investments in stormwater infrastructure have exposed some residents to poor …

Shadow Rate Models And Monetary Policy, Ethan Struby, Michael F. Connolly

Department of Economics Working Paper Series

We examine the channels and efficacy of monetary policy at the zero lower bound (ZLB) through the lens of shadow rate models. We compare estimates across models with various factor structures and different assumptions about interest rate forecasts. We confirm that calendar-based forward guidance discretely shifted the implied duration of the ZLB and that large scale asset purchases (LSAPs) primarily lowered term premia. However, we find that the real effects of monetary policy are more muted relative to prior estimates: a 1 standard deviation fall in the shadow rate causes a peak decline in the unemployment rate of 0.003-0.01%.

The Effects Of Exogenous Virilizing Testosterone On Strength Training And Self-Compassion In Transgender Nonbinary Individuals, Nadine Sikora

All NMU Master's Theses

Previous exercise science research has excluded transgender nonbinary individuals from their studies. Exercise has been shown to improve symptoms of depression and anxiety as well as improve body composition. Purpose: Identify the impacts of exogenous testosterone on relative strength and levels of self-compassion in transgender nonbinary individuals. Methods: Eighteen untrained individuals (6 transgender nonbinary, 6 ciswomen, and 6 cismen, mean age of 23.7 ± 3.5 years) were recruited and randomly assigned to an 8-week resistance training group or a non-exercise control group. Participants completed a 12-question survey of self-compassion followed by, assessment of strength for chest and leg …

Estimating Giraffe (Giraffa Camelopardalis) Population Size And Survival Rates In South Luangwa Valley, Zambia, Samantha Phillips

All NMU Master's Theses

Giraffe populations across their range have declined significantly over the past 40 years. Recent studies of these declines noted that conservation efforts often lack basic population estimates and descriptions of demographic parameters such as sex- and age-specific survival rates. I addressed those research needs for a geographically-isolated population of giraffes (Giraffa camelopardalis) in South Luangwa Valley, Zambia. During 2016 to 2018, collaborators opportunistically photographed giraffes throughout South Luangwa National Park and adjacent Lupande and Lumimba Game Management Areas. Given that each giraffe has a unique spotting pattern, I created a photo inventory of the population and developed an …

The Relationship Between Cognitive Flexibility And Rumination: From Laboratory To Daily Life, Cassidy R. Girard

All NMU Master's Theses

Cognitive flexibility has been considered one of the risk factors for anxiety. People with high levels of anxiety tend to stick to more maladaptive strategies such as rumination. The interaction between cognitive flexibility and rumination may help explain the contribution of cognitive flexibility to the development of anxiety. This study investigated the relationship between cognitive flexibility and rumination. Each individual’s level of cognitive flexibility, anxiety, and rumination were measured through questionnaires and computer tasks. Daily changes in emotion and rumination were assessed using the experience sampling method. The results showed interesting relationship between rumination (both trait and momentary) and cognitive …

Concussion And Mental Health: Case Series, Haley M. Clark

All NMU Master's Theses

Concussion is the most common traumatic brain injury in the United States, and is thought to lead to adverse effects on mental health. No studies to date have examined mental health throughout concussion recovery. This project examined the effect of concussion on three aspects of mental health: anxiety (Hamilton Anxiety Rating Scale), depression (Beck’s Depression Inventory), and aggression, (Buss-Perry Aggression Questionnaire) at three time points (baseline, mid-season, and postseason) and if the athlete had a concussion, they completed the questionnaire once upon diagnosis, bi-weekly until return-to-play, and bi-weekly for two weeks after being cleared for participation. Each concussion showed an …

Management Of Youth Sport-Related Concussion By Urban And Rural Practitioners: A Pilot Study, Brett R. Fox

All NMU Master's Theses

Sport-related concussions (SRC) occur at alarming rates among high school athletes (ages 13-18), which made the Center for Disease Control and Prevention and other agencies classify it as an “epidemic”. If improperly managed, physical, mental, and emotional consequences can occur for SRC patients. Due to these consequences all 50 states in the US have passed legislation requiring medical release from a practitioner before a student-athlete can return to athletics following an SRC, yet there is no universally accepted consensus on how to medically manage this common injury. A 22-item, validated survey was distributed to Michigan practitioners who sign off on …

Teaching Perspective Taking Skills To Children With Autism Spectrum Disorder, Mitchell Cox

All NMU Master's Theses

Children diagnosed with Autism Spectrum Disorder (ASD) often lack perspective taking skills as evidenced by deficits in social communication and social interaction. The PEAK-T program Deictic: Single-Reversal I and You has previously been utilized to teach and establish singular I-YOU perspective taking repertoires in children with ASD, however no such studies exist for teaching plural WE-THEY perspective taking repertoires. The present study replicated the methods from a previous study (Belisle et al., 2016) to establish simple and single-reversal I-YOU deictic relations, and extended the evaluation to establish simple and single-reversal WE-THEY deictic relations. Of the four participants in this study, …

Measuring Affective Responses To Different Types Of Nature Exposure, Abigail P. Moffett

All NMU Master's Theses

Natural environments provide many physical and physiological benefits for an individual. Examples may include decreased stress levels, increased intrinsic motivations and prosocial behavior, and more. Fueled by the curiosity of the extent to which nature provides these benefits, this study investigated whether pre-existing preference for either waterscape scenes or mountainous scenes, as well as self-reported affective and associative responses to those environmental exposures are possible explanations for the experience of wellbeing when one is exposed to nature. Measures included the Nature Relatedness Scale, State Vitality Scale, Positive and Negative Affect Scale, and a nature preference scale (mountainous vs. waterscape). Nature …

Additionally, due to the uniqueness of its heating mechanism, the synthesis of materials in various nanostructured forms through microwave-assisted methods has been of great interest and is widely pursued. The materials thus synthesized have been applied as sensing elements in gas sensors, luminescent …

Modeling Triaxial Testing With Flexible Membrane To Investigate Effects Of Particle Size On Strength And Strain Properties Of Cohesionless Soil, Thang Pham, Md. Wasif Zaman, Thuy Vu

Civil Engineering Faculty Publications

A 3D DEM model using Particle Flow Code (PFC3D) software was developed utilizing a bonded-ball flexible membrane approach to study cohesionless soil as a discontinuous discrete material. This approach is not yet widely used because of its complexity and high computational cost, but it allowed the authors to observe the stress-strain curves of triaxial specimens, to single out effects of individual factors on the strength and strain properties, and to observe the formation of the shear band and failure surface. The 3D model was calibrated and verified with experimental data, and a sensitivity analysis was carried out for the microparameters. …

Planetary Engineering Ethics: Mechanisms, Issues, And Consequences Of Terraforming, Haruka Kido

Electrical Engineering Student Publications

This research and analysis paper addresses the extension of environmental ethics in the area of planetary engineering, specifically using the following three ethical viewpoints that inevitably shape our perceptions of the terraforming endeavors proposed to build our cosmological future appropriately: [1] environmental ethics analysis, [2] moral theories analysis (including utilitarianism, Respect for Persons ethics or “RP ethics,” and virtue ethics), and [3] risk analysis. The three ethical viewpoints, explained in “Concepts and Cases: Engineering Ethics. 6th Edition,” are used to elaborate justifications for or against terraforming beyond the mere theoretical explanations. To develop …

Temporal Lidar Scanning In Quantifying Cumulative Rockfall Volume And Hazard Assessment: A Case Study At Southwestern Saudi Arabia, Abdullah A. Alotaibi, Norbert H. Maerz, Kenneth J. Boyko, Ahmed M. Youssef, Biswajeet Pradhan

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Rockfalls and unstable slopes pose a serious threat to people and property along roads/highways in the southwestern mountainous regions of Saudi Arabia. In this study, the application of terrestrial light detection and ranging (LiDAR) technology was applied aiming to propose a strategy to analyze and accurately depict the detection of rockfall changes, calculation of rockfall volume, and evaluate rockfall hazards along the Habs Road, Jazan Region, Saudi Arabia. A series of temporal LiDAR scans were acquired at three selected sites. Our results show that these three sites have different degrees of hazard due to their geological differences. The mean volume …

Sound And Complete Certificates For Quantitative Termination Analysis Of Probabilistic Programs, Krishnendu Chatterjee, Amir Kafshdar Goharshady, Tobias Meggendorfer, Dorde Zikelic

Research Collection School Of Computing and Information Systems

We consider the quantitative problem of obtaining lower-bounds on the probability of termination of a given non-deterministic probabilistic program. Specifically, given a non-termination threshold p∈[0,1], we aim for certificates proving that the program terminates with probability at least 1−p. The basic idea of our approach is to find a terminating stochastic invariant, i.e. a subset SI of program states such that (i) the probability of the program ever leaving SI is no more than p, and (ii) almost-surely, the program either leaves SI or terminates.While stochastic invariants are already well-known, we provide the first proof that the idea above is …

Multimodal Private Signatures, Khoa Nguyen, Fuchun Guo, Willy Susilo, Guomin Yang

Research Collection School Of Computing and Information Systems

We introduce Multimodal Private Signature (MPS) - an anonymous signature system that offers a novel accountability feature: it allows a designated opening authority to learn some partial information op about the signer’s identity id, and nothing beyond. Such partial information can flexibly be defined as op = id (as in group signatures), or as op = 0 (like in ring signatures), or more generally, as op = Gj (id), where Gj (·) is a certain disclosing function. Importantly, the value of op is known in advance by the signer, and hence, the latter can decide whether she/he wants to disclose …

Integrating Forward And Reverse Logistics In Vehicle Routing Problem With Cross-Docking, Vincent F. Yu, Pham T. Anh, Aldy Gunawan

Research Collection School Of Computing and Information Systems

A closed-loop supply chain is one of the vital parts for maintaining the success of enterprises, where forward and reverse logistics are integrated to eliminate wastes (e.g., transportation costs). However, previous studies related to the Vehicle Routing Problem have almost overlooked this integration. This research therefore introduces a variant of the Vehicle Routing Problem with cross-docking (VRPCD) by simultaneously considering three additional factors: (1) various types of vehicles in terms of their capacities and unit travel costs; (2) multiple cross-docks; and (3) the integration of forward and reverse logistics. In particular, the flows of the network consist of distributing goods …

Legion: Massively Composing Rankers For Improved Bug Localization At Adobe, Darryl Jarman, Jeffrey Berry, Riley Smith, Ferdian Thung, David Lo

Research Collection School Of Computing and Information Systems

Studies have estimated that, in industrial settings, developers spend between 30 and 90 percent of their time fixing bugs. As such, tools that assist in identifying the location of bugs provide value by reducing debugging costs. One such tool is BugLocator. This study initially aimed to determine if developers working on the Adobe Analytics product could use BugLocator. The initial results show that BugLocator achieves a similar accuracy on five of seven Adobe Analytics repositories and on open-source projects. However, these results do not meet the minimum applicability requirement deemed necessary by Adobe Analytics developers prior to possible adoption. Thus, …

Efficient Resource Allocation With Fairness Constraints In Restless Multi-Armed Bandits, Dexun Li, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Restless Multi-Armed Bandits (RMAB) is an apt model to represent decision-making problems in public health interventions (e.g., tuberculosis, maternal, and child care), anti-poaching planning, sensor monitoring, personalized recommendations and many more. Existing research in RMAB has contributed mechanisms and theoretical results to a wide variety of settings, where the focus is on maximizing expected value. In this paper, we are interested in ensuring that RMAB decision making is also fair to different arms while maximizing expected value. In the context of public health settings, this would ensure that different people and/or communities are fairly represented while making public health intervention …

Joint Chance-Constrained Staffing Optimization In Multi-Skill Call Centers, Tien Thanh Dam, Thuy Anh Ta, Tien Mai

Research Collection School Of Computing and Information Systems

This paper concerns the staffing optimization problem in multi-skill call centers. The objective is to find a minimal cost staffing solution while meeting a target level for the quality of service (QoS) to customers. We consider a staffing problem in which joint chance constraints are imposed on the QoS of the day. Our joint chance-constrained formulation is more rational capturing the correlation between different call types, as compared to separate chance-constrained versions considered in previous studies. We show that, in general, the probability functions in the joint-chance constraints display S-shaped curves, and the optimal solutions should belong to the concave …

Fed-Ltd: Towards Cross-Platform Ride Hailing Via Federated Learning To Dispatch, Yansheng Wang, Yongxin Tong, Zimu Zhou, Ziyao Ren, Yi Xu, Guobin Wu, Weifeng Lv

Research Collection School Of Computing and Information Systems

Learning based order dispatching has witnessed tremendous success in ride hailing. However, the success halts within individual ride hailing platforms because sharing raw order dispatching data across platforms may leak user privacy and business secrets. Such data isolation not only impairs user experience but also decreases the potential revenues of the platforms. In this paper, we advocate federated order dispatching for cross-platform ride hailing, where multiple platforms collaboratively make dispatching decisions without sharing their local data. Realizing this concept calls for new federated learning strategies that tackle the unique challenges on effectiveness, privacy and efficiency in the context of order …

Finding Meta Winning Ticket To Train Your Maml, Dawei Gao, Yuexiang Xie, Zimu Zhou, Zhen Wang, Yaliang Li, Bolin. Ding

Research Collection School Of Computing and Information Systems

The lottery ticket hypothesis (LTH) states that a randomly initialized dense network contains sub-networks that can be trained in isolation to the performance of the dense network. In this paper, to achieve rapid learning with less computational cost, we explore LTH in the context of meta learning. First, we experimentally show that there are sparse sub-networks, known as meta winning tickets, which can be meta-trained to few-shot classification accuracy to the original backbone. The application of LTH in meta learning enables the adaptation of meta-trained networks on various IoT devices with fewer computation. However, the status quo to identify winning …
