The Utility Of Clinical And Blood-Based Biomarkers To Discriminate Between Typical And Prolonged Pediatric Mtbi Symptom Recovery, Morgan E. Nitta Jul 2022

The Utility Of Clinical And Blood-Based Biomarkers To Discriminate Between Typical And Prolonged Pediatric Mtbi Symptom Recovery, Morgan E. Nitta

Dissertations (1934 -)

Prolonged recovery following mild traumatic brain injury (mTBI) is poorly understood, particularly in pediatric samples, despite significant work to understand prolonged postconcussive symptoms (PPS). Emerging evidence in adult mTBI literature suggests blood-based biomarkers have diagnostic and prognostic value, but there is limited research examining this in pediatric mTBI. Further, while adult research documents that combining physiological biomarkers, emotional distress and symptom reports more optimally differentiates between mTBI and healthy controls, it is unknown if this finding will replicate in pediatric samples. This project examined foundational relationships between clinical, cognitive, inflammatory markers, and kynurenine pathway (KP) metabolites following mTBI in adolescents …

Illusory Vowels And The North Kyungsang Korean Vowel Merger In English Loanword Adaptation Into Korean, Jiyeon Song Jul 2022

Illusory Vowels And The North Kyungsang Korean Vowel Merger In English Loanword Adaptation Into Korean, Jiyeon Song

Theses and Dissertations

Our auditory perceptual processing is optimized for the sound patterns of our native language. Consequently, when non-native segments are perceived, speech “illusions” often occur. This well-known phenomenon, known as the perception of illusory vowels, occurs when listeners of a borrowing language (BL) perceive vowels that do not exist underlyingly in the source language (SL).

Illusory vowels have often been considered to be the default vowel in a language: /ɨ/ in Korean, /u/ in Japanese, /ə/ in English, /e/ in Spanish, and /i/ in Brazilian Portuguese. This raises the question of how vowel systems affect the quality of illusory vowels. For …


An Examination Of The Effects Of The Presentation Of Preferred Items On Frequency Of Stereotypy In Children With Autism Spectrum Disorder, Shauna Blady Jul 2022

An Examination Of The Effects Of The Presentation Of Preferred Items On Frequency Of Stereotypy In Children With Autism Spectrum Disorder, Shauna Blady

Theses and Dissertations

Stereotypy is a restricted, repetitive behavior that features rigidity and invariance. Approximately 88% of individuals with Autism Spectrum Disorder (ASD) exhibit some form of stereotypy (Chebli et al., 2016). Although it often occurs under conditions of stimulus deprivation, stereotypy may also occur under other environmental conditions. The purpose of this study was to evaluate the occurrence of stereotypy when preferred items are available noncontingently. Three participants were exposed to a baseline condition in which they had no access to items, followed by conditions in which high and low preferred items were delivered noncontingently to investigate whether automatically-maintained stereotypy was likely …


Comparison Of Traditional And Eye-Gaze Preference And Reinforcer Assessments, Zhihao Ou Jul 2022

Comparison Of Traditional And Eye-Gaze Preference And Reinforcer Assessments, Zhihao Ou

Theses and Dissertations

A variety of preference assessments have been used to identify potential reinforcers for individuals with autism spectrum disorder (ASD) and related disabilities. However, during traditional selection-based assessments, participants may fail to select items or selection may be under faulty stimulus control (e.g., side bias). Previous research has evaluated the utility of eye-gaze preference assessments with individuals with profound intellectual disabilities. The purpose of this study is to compare preference assessments by eye gaze and traditional preference assessment in three participants with ASD. The results of reinforcer assessment showed that among 2 out of 3 participants, the eye gaze method was …


Teaching Children With Autism To Tact Private Events Based On Common Properties, Madisyn Quidort Jul 2022

Teaching Children With Autism To Tact Private Events Based On Common Properties, Madisyn Quidort

Theses and Dissertations

Skinner (1957) proposed that people learn to talk about private events in several ways. This study sought to examine the plausibility of one of those mechanisms: common properties. Skinner asserted that children learn tacts for public stimuli through normal interaction with their caregivers. When a child experiences a private stimulus that shares some feature with a previously learned public stimulus, the child generalizes the tact to the private sensation because there is a common property between the two stimuli. Three children with autistic disorder were taught 6 to 9 sensation tacts (e.g., prickly, cozy, tight) depicted in videos (e.g., a …


The Effects Of Teaching Children To Tact Their Emotions On Problem Behavior, Haley Nicole Harber Jul 2022

The Effects Of Teaching Children To Tact Their Emotions On Problem Behavior, Haley Nicole Harber

Theses and Dissertations

Children with autism spectrum disorder (ASD) often struggle to understand and describe private events, such as emotions. When an individual cannot communicate appropriately, it can lead to various problem behaviors. Previous literature suggested that we teach children to tact their emotions (e.g., "I am sad," "I am angry") in an attempt to decrease their problem behavior. The primary purpose of the current study is to teach children with autism to tact their emotions. The secondary purpose is to evaluate the effects of empathy statements on problem behavior. Four children participated, three with problem behavior maintained by access to tangibles and …


The Effects Of Guided Notes In An Online Behavior Analysis Graduate Course, Natalya Theresa Gutierrez Jul 2022

The Effects Of Guided Notes In An Online Behavior Analysis Graduate Course, Natalya Theresa Gutierrez

Theses and Dissertations

Guided notes are handouts with fill-in-the-blank spots, incomplete outlines, or PowerPoint slides with blank spaces identical to those used by the instructor during class lectures (Biggers et al., 2020). This note-taking strategy was initially created for those who have difficulty in the classroom, such as students with learning disabilities (Williams et al., 2012). However, guided notes became a supplemental note-taking technique used during lectures for non-disabled college students as well. The authors examined the impact of guided notes in an online course format, counterbalancing three conditions across participants and instructional units: Guided notes, learning objectives and no notes to determine …


A Comparative Assessment Of Tagteach® And Video Self-Evaluation On Increasing Fluency Of Dance Movements, Eliza Jane Goben Jul 2022

A Comparative Assessment Of Tagteach® And Video Self-Evaluation On Increasing Fluency Of Dance Movements, Eliza Jane Goben

Theses and Dissertations

Dance coaching and education is a rapidly evolving field both within behavior analysis and in other disciplines. Previous behavior analytic research in dance or similar athletics has demonstrated the effectiveness of video feedback/self-evaluative video feedback and TAGteach® separately. However, there is no published research comparing these two interventions. The present study applied an adapted alternating treatment design to examine the effects of TAGteach™ versus self-evaluative video feedback in improving the accuracy of dance movements in beginner level dance students. All participants demonstrated a visibly greater increase in skills paired with TAGteach™ compared to skills paired with video self-evaluation.


Increasing Practical Verbal Behavior In Esports Players, Victoria Perry German Jul 2022

Increasing Practical Verbal Behavior In Esports Players, Victoria Perry German

Theses and Dissertations

Verbal behavior, sports, and performance skills have been targeted in behavior analytic research in the past. However, no research to date has targeted Esports as a setting, nor has there been a substantial focus on communication as a target as opposed to more technical skills in sports, organizations, or similar settings. Esports is a large, growing industry of competitive videogaming, with a variety of games represented at different levels, many of which are team-based and require significant coordination and cooperation between players on a team. Thus, in this study we targeted verbal responses in a team of collegiate Esports players …

Towards Codes Of Practice For Navigating The Academic Peer Review Process, Benjamin K. Sovacool, Jonn Axsen, Laurence L. Delina, Hilary Schaffer Boudet, Varun Rai, Roman Sidortsov, Sefa Awaworyi Churchill, Kirsten E.H. Jenkins, Ray Galvin

Michigan Tech Publications, Part 1

Peer review is the bedrock of modern academic research and its lasting contributions to science and society. And yet, reviewers can submit “poor” peer review reports, authors can blatantly ignore referee advice, and editors can contravene and undermine the peer review process itself. In this paper, we, the Editors of Energy Research & Social Science (ER&SS), seek to establish peer review codes of practice for the general energy and social science research community. We include suggestions for three of the most important roles: peer reviewers or referees, editors, and authors. We base our 33 recommendations on a collective 60 years …


Why Do U.S. Firms Invest Less Over Time?, Fangjian Fu, Sheng Huang, Rong Wang Jul 2022

Why Do U.S. Firms Invest Less Over Time?, Fangjian Fu, Sheng Huang, Rong Wang

Research Collection Lee Kong Chian School Of Business

Capital expenditures of U.S. public firms, relative to total assets, decrease by more than half from 1980 to 2020. The decline is pervasive across industries and firms of different characteristics and cannot be explained by the usual determinants of investment and many other seemingly plausible reasons. The decline is consistent with the transformation in production technology — firms rely more on intangible capital and less on fixed assets in production. Industry-level analyses yield supporting evidence. We observe similar declining trend in capital expenditure in other developed countries but not in most emerging markets.

Understanding The Impact Of Emotional Support On Mental Health Resilience Of The Community In The Social Media In Covid-19 Pandemic, Xuan Hu, Yanqing Song, Ruilin Zhu, Shuang He, Bowen Zhou, Xuelian Li, Han Bao, Shan Shen, Bingsheng Liu

Research Collection Lee Kong Chian School Of Business

Background: Emotional support in social media can act as a buffer against the negative impact of affective disorders. However, empirical evidence relating to emotional support in social media and how it influences the wider public remains scanty. The objective of this study is therefore to conduct a prototype investigation into the translation mechanism of emotional support in social media, providing empirical evidence for practitioners to use to tackle mental health issues for the wider public. Methods: A regression model is proposed to examine the relationship between perceived and received emotional support. Received emotional support is set as the dependent variable …


Gamifying An Assessment Method: What Signals Are Organizations Sending To Applicants?, Konstantina Georgiou, Filip Lievens Jul 2022

Gamifying An Assessment Method: What Signals Are Organizations Sending To Applicants?, Konstantina Georgiou, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Purpose: The paper aims to expand the authors' knowledge on gamification and the signals sent on behalf of the organization when gamified assessments are used. The authors examine the mechanisms through which the use of gamification into an assessment method may increase the attractiveness of an organization as a prospective employer. Design/methodology/approach: The first study examines, following a longitudinal design, the signals that an organization sends to applicants about the organization's symbolic traits (e.g. innovativeness), through the characteristics of a gamified assessment, in terms of enjoyment and flow and impact on organizational attractiveness. Upon clarifying this mechanism, the second study …


What, Why And How Financial Development Matters: Evidence Of Asean-5, Asia-5 And Oecd-7 Economies, Swee Liang Tan Jul 2022

What, Why And How Financial Development Matters: Evidence Of Asean-5, Asia-5 And Oecd-7 Economies, Swee Liang Tan

Research Collection School Of Economics

This paper analyzed the association between bank and capital markets financial development with income per capita in three regions; ASEAN-5 economies (Singapore, Malaysia, Thailand, Philippines, Indonesia), Asia-5 (Japan, China, Hong Kong SAR, South Korea, and India), and OECD-7 (Australia, Canada, Denmark, Norway, Sweden, UK, and US) from 2000 to 2017 using panel data regressions. A key lesson ASEAN-5 can learn from Asia-5 and OECD-7 experience is that bank size does matter despite digital disruptions to their banking system; yet large financial structure that favors banks is negatively associated with Asia-5, and importantly, efficient banking system (not bank size alone) is …

Values Assessment For Personnel Selection: Comparing Job Applicants To Non-Applicants, Jeromy Anglim, Karlyn Molloy, Patrick D. Dunlop, Simon L. Albrecht, Filip Lievens, Marty Andrew

Research Collection Lee Kong Chian School Of Business

Some scholars suggest that organizations could improve their hiring decisions by measuring the personal values of job applicants, arguing that values provide insights into applicants’ cultural fit, retention prospects, and performance outcomes. However, others have expressed concerns about response distortion and faking. The current study provides the first large-scale investigation of the effect of the job applicant context on the psychometric structure and scale means of a self-reported values measure. Participants comprised 7,884 job applicants (41% male; age M = 43.32, SD = 10.76) and a country-, age-, and gender-matched comparison sample of 1,806 non-applicants (41% male; age M = …


Beyond The High Ground: A Taxonomy For Earth-Moon System Operations, Adam P. Wilmer, Robert A. Bettinger Jul 2022

Beyond The High Ground: A Taxonomy For Earth-Moon System Operations, Adam P. Wilmer, Robert A. Bettinger

Faculty Publications

Situational and space domain awareness in the space domain can no longer be confined to that which is found in geosynchronous orbit. International activities—commercial and military—and threats to the planet itself exist and are increasing across the entire Earth-Moon system. This reality requires a new taxonomy to accurately classify space domain awareness missions and better apply resources to and development of the same. This work presents such a taxonomy for the classification of space domain awareness regions.

Center for Medical Ethics and Health Policy Staff Publications

Somatic copy number alterations (SCNAs) in tumors are clinically significant diagnostic, prognostic, and predictive biomarkers. SCNA detection from targeted next-generation sequencing panels is increasingly common in clinical practice; however, detailed descriptions of optimization and validation of SCNA pipelines for small targeted panels are limited. This study describes the validation and implementation of a tumor-only SCNA pipeline using CNVkit, augmented with custom modules and optimized for clinical implementation by testing reference materials and clinical tumor samples with different classes of copy number variation (CNV; amplification, single copy loss, and biallelic loss). Using wet-bench and in silico methods, various parameters impacting CNV …

Entering Dystopia: Should Your Face Be The Key To Your Fate?, Shilpa Madan, Krishna Savani, Gita V. Johar

Research Collection Lee Kong Chian School Of Business

How would you feel if you were rejected from a job because you didn't look competent enough? Or if you were apprehended at a public place by the police because you looked like a criminal? Although these scenes sound dystopic and generate a sense of fear and anxiety, technology that claims that people's traits can be inferred from their faces already exists and is being used by businesses and governments worldwide.


Exploring The Empirical Relationship Between Inner-City Blight And Urban Sprawl In The United States, Eric Fesselmeyer, Kiat Ying Seah Jul 2022

Exploring The Empirical Relationship Between Inner-City Blight And Urban Sprawl In The United States, Eric Fesselmeyer, Kiat Ying Seah

Research Collection College of Integrative Studies

Urban blight has been found to cause a variety of problems, including negatively affecting the value of surrounding properties and increasing neighborhood crime rates. If the same externalities that give rise to urban sprawl also contribute to urban blight, as is suggested by Brueckner and Helsley (2011), city center vacancy rates-an indication of blight-would increase with the extent of urban sprawl. This study adds to the sparse literature on the empirical relationship between urban sprawl and blight by finding that the city-center census tract vacancy rate is higher in more sprawling cities. The results of this article, therefore, provide support …


Provider Perceptions Of Telehealth And In-Person Exposure And Response Prevention For Obsessive-Compulsive Disorder, Andrew D Wiese, Kendall N Drummond, Madeleine N Fuselier, Jessica C Sheu, Gary Liu, Andrew G Guzick, Wayne K Goodman, Eric A Storch Jul 2022

Provider Perceptions Of Telehealth And In-Person Exposure And Response Prevention For Obsessive-Compulsive Disorder, Andrew D Wiese, Kendall N Drummond, Madeleine N Fuselier, Jessica C Sheu, Gary Liu, Andrew G Guzick, Wayne K Goodman, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

Until recently, psychotherapies, including exposure and response prevention (ERP) for obsessive-compulsive disorder (OCD), have primarily been delivered in-person. The COVID-19 pandemic required OCD providers delivering ERP to quickly transition to telehealth services. While evidence supports telehealth ERP delivery, limited research has examined OCD provider perceptions about patient characteristics that are most appropriate for this modality, as well as provider abilities to identify and address factors interfering with effective telehealth ERP. In the present study, OCD therapists (N = 113) rated the feasibility of delivering telehealth ERP relative to in-person for different (1) patient age-groups, (2) levels of OCD severity, and …

Contracting Strategies: A Different Approach To Address Long-Term Performance, Maria Calahorra-Jimenez Jul 2022

Contracting Strategies: A Different Approach To Address Long-Term Performance, Maria Calahorra-Jimenez

Mineta Transportation Institute

For cost-efficiency, public safety, and sustainability, improving long-term performance in highway projects is imperative for public administrations. Project delivery and procurement methods provide an opportunity to align design and construction processes with this goal. While previous studies have explored whether project delivery methods impact the long-term performance of highway projects, these studies did not focus on how core elements within project procurement relate to long-term performance. Thus, to fill this gap, this research explores how and to what extent long-term evaluation criteria are considered in design-build best-value procurement of highway projects. To this end, the team conducted content analysis on …


Connected Simulation For Work Zone Safety Application, Vahid Balali Jul 2022

Connected Simulation For Work Zone Safety Application, Vahid Balali

Mineta Transportation Institute

Every year, over 60,000 work zone crashes are reported in the United States (FHWA 2016). Such work zone crashes have resulted in over 4,400 fatal and 200,000 non-fatal injuries in the last 5 years (FHWA 2016, BLS 2014). Apart from the physical and emotional trauma, the annual cost of these injuries exceeds $4 million-representing significant wasted resources. To improve work zone safety, this research developed a system architecture for unveiling high-risk behavioral patterns among highway workers, equipment operators, and drivers within dynamic highway work zones. This research implemented the use of a connected virtual environment, which is an immersive hyper-realistic …
