Opening The Black Box Of Fitness Tracking: Understanding The Mechanisms Of Feedback In Motivating Physical Activity Among Older Singaporeans, Sapphire H. Lin, Rich Ling, Sonny Rosenthal

Research Collection College of Integrative Studies

This paper examines how older adults interact with fitness trackers and how that interaction influences their physical activity. We carried out qualitative interviews with 22 individuals between the ages of 55 and 72 who had used fitness trackers as part of a six-week field experiment investigating the effects of feedback from fitness trackers and the social influence of their spouses. From their comments, we derived an explorative process model explaining the mechanisms and the four stages of effects arising from personalised feedback, namely, cognitive, affective, conative, and intuitive. These effects were grouped into internal and external dimensions. Three types of …

Exposure To Preference-Matched Alcohol Advertisements From National Sports Broadcasts Increases Short-Term Alcohol Consumption Inclinations In Risky Drinkers, Ross C. Hollett, Jesse Fairclough, Julia Butt, Brennen Mills

Research outputs 2022 to 2026

Background: In Australia, sports broadcasting is afforded special alcohol advertising rights during daytime hours, which raises public health concerns, including short-term increases in alcohol consumption among the broad viewership of national sporting codes. Methods: We conducted a content analysis across a sample of nationally televised finals matches (N = 16) from the Australian Football League (AFL) and the National Rugby League (NRL) to determine the prevalence of alcohol advertising video clips during these broadcasts. We also conducted an online experiment exposing participants (N = 345) to a randomly selected alcohol advertisement and measured the immediate effects on self-reported alcohol craving …

An Exploration Into How Print And Online News Journalists Manage Political Fake News In Ireland, John William Hogan

Conference papers

This paper examines how a number of Irish political journalists, working for both traditional newspapers and an online news website, deal with the problem of fake news. The aim is to gain an understanding of what the journalists’ perception of political fake news is and the methods they employ to manage it - a sorely under researched topic. Our findings show that the journalists we spoke with feel there are a range of forms that fake news assumes, many of them insidious and challenging to overcome with facts. The paper highlights the important role journalists play in confronting political fake …

Assessment Of Simultaneous Alcohol And Cannabis Use And Its Related Consequences And Cognitions In College Students: A Narrative Review, Jennifer L. Shipley, Abby L. Braitman

Psychology Faculty Publications

As rates of students using cannabis continue to rise, simultaneous use of alcohol and cannabis (such that their effects overlap; commonly referred to as simultaneous alcohol and marijuana [SAM] use) is prevalent among college students who use both substances. Although research focusing on SAM use and related cognitions and consequences continues to grow, there are no common established measures, as approaches vary across studies. This narrative review identifies current methods for assessing SAM use and measures of SAM-related consequences and cognitions (motives and expectancies) among college students, evaluates how they were developed, identifies gaps in the literature, and provides recommendations …

Mental Workload Modulates The Effects Of Baroreceptor Afferents On Sensorimotor Processing, Xiao Yang, Katie Herberlein, Anthony Reid, Dongfang Jiao, Fang Fang

Psychology Faculty Publications

The heart–brain interaction is the main mechanism for maintaining normative physiological processes, and its dysregulation underlies the somatic symptoms of various mental disorders. Cortical inhibition, triggered by afferent signals from baroreceptor activation, induces systematic variations in sensorimotor responses within a cardiac cycle, with reaction times (RTs) slower at cardiac systole compared to diastole (known as cardiac cycle time effects). However, recent data suggest that baroreceptor afferents not only inhibit simple responses but also facilitate complex sensorimotor responses during cardiac systole. The mental workload that is implicated in complex responses may modulate the cardiac cycle time effects. The current study aimed …

Adherence To Personal Protective Equipment Practices During The Covid-19 Pandemic: A Pilot Study, Taryn Amos, Cameron Griffin, Joshua K. Schaffzin, Andrea Ankrum, Felicia Scaggs Huang

Psychology Faculty Publications

A direct observational pilot project of healthcare personnel (HCP) was conducted to validate a tool that measures personal protective equipment (PPE) adherence at a large pediatric institution. Overall unit PPE adherence for all moments ranged from 50-61%. Masking was the most adhered to PPE moment (100%); hand hygiene prior to donning PPE had the lowest adherence (13%). Using data from this standardized tool, researchers can evolve PPE standards to maximize their adherence, effectiveness, and ease of utilization.

Psychology Faculty Publications

Teen-to-teen (t2t) crisis lines are a special type of crisis service where youth volunteers help their peers. Although prior research has examined the experience of adult crisis line responders, no research has examined the experience of adolescents who do this work. In collaboration with two of the largest t2t lines in the U.S., this pilot study is the first examination of t2t crisis line work. Volunteers (ages 14–20) reported: their primary motivation for joining the crisis lines was to help others and give back to the community; responding to a range of peers’ problems on the t2t crisis line, …

Sleep Disturbances And Psychological Well-Being Among Military Medical Doctors Of The Swiss Armed Forces: Study Protocol, Rationale And Development Of A Cross-Sectional And Longitudinal Interventional Study, Dena Sadeghi-Bahmani, Viola Rigotti, Zeno Stanga, Undine E. Lang, Rebecca K. Blais, Michelle L. Kelley, Serge Brand

Psychology Faculty Publications

Background: Compared to civilians and non-medical personnel, military medical doctors are at increased risk for sleep disturbances and impaired psychological well-being. Despite their responsibility and workload, no research has examined sleep disturbances and psychological well-being among the medical doctors (MDs) of the Swiss Armed Forces (SAF). Thus, the aims of the proposed study are (1) to conduct a cross-sectional study (labeled ‘Survey-Study 1’) of sleep disturbances and psychological well-being among MDs of the SAF; (2) to identify MDs who report sleep disturbances (insomnia severity index >8), along with low psychological well-being such as symptoms of depression, anxiety and stress, but …

A Meta-Analysis Of Attachment At Work, Kate N. Warnock, Christina S. Ju, Ian M. Katz

Psychology Faculty Publications

This meta-analysis aimed to confirm and clarify the relationships between attachment style and various workplace correlates, including job performance, burnout, personality, and job satisfaction (K = 109 independent samples, N = 32,278 participants). Results provided the strongest support for the relationships between attachment style and the Big Five personality traits, burnout, and job performance. Anxious attachment was also related to a host of other correlates, including job stress, turnover intentions, job satisfaction, and work engagement. Additionally, dominance analysis was used and found that attachment style had incremental validity beyond the Big Five in the prediction of job performance, job satisfaction, …

Short-Term Blood Pressure Variability Among Young Adults At High Or Low Risk For Depression, Balázs Bence Nyárády, Miklós Vértes, Edit Dósa, Xiao Yang, Charles J. George, Enikõ Kiss, Iidiko Baji, Krisztina Kapornai, Maria Kovacs

Psychology Faculty Publications

Background: Depression has been shown to have adverse effects on blood pressure (BP) and is associated with high blood pressure variability (BPV). In turn, high short-term BPV has been related to eventual cardiovascular risk. But it is not clear how early in adulthood the detrimental effects of depression on BPV may be discerned, if being at high risk for depression also compromises BPV, and whether the clinical features of depression moderate its adverse effects. We investigated these three issues among young adults using an office-like setting. Methods: In total, 218 subjects with a history of childhood-onset major depressive episodes (probands), …

Optimal Nonparametric Range-Based Volatility Estimation, Tim Bollerslev, Jia Li, Qiyuan Li

Research Collection School Of Economics

We present a general framework for optimal nonparametric spot volatility estimation based on intraday range data, comprised of the first, highest, lowest, and last price over a given time-interval. We rely on a decision-theoretic approach together with a coupling-type argument to directly tailor the form of the nonparametric estimator to the specific volatility measure of interest and relevant loss function. The resulting new optimal estimators offer substantial efficiency gains compared to existing commonly used range-based procedures.

Note On Fuel Consumption In Ocean Container Shipping: Bounds On Fuel Usage, Manwo Ng

Information Technology & Decision Sciences Faculty Publications

This paper contributes to the literature by deriving upper and lower bounds on the fuel consumption in container shipping. The bounds are derived from sailing distances, port times, and the possible arrival times at ports/ the berth windows negotiated between the ocean carrier and the port operators. Crucially, the derived bounds can be used in conjunction with any of the common fuel consumption functions proposed in the literature. This latter is especially important since currently there is no consensus on a specific functional form for the fuel consumption function. The behavior of the bounds will be illustrated with numerical examples.

High-Dimensional Iv Cointegration Estimation And Inference, Peter C. B. Phillips, Igor L. Kheifets

Research Collection School Of Economics

A semiparametric triangular systems approach shows how multicointegrating linkages occur naturally in an I(1) cointegrated regression model when the long run error variance matrix in the system is singular. Under such singularity, cointegrated I(1) systems embody a multicointegrated structure that makes them useful in many empirical settings. Earlier work shows that such systems may be analyzed and estimated without appealing to the associated I(2) system but with suboptimal convergence rates and potential asymptotic bias. The present paper develops a robust approach to estimation and inference of such systems using high dimensional IV methods that have appealing asymptotic properties like those …

Statistical Discrimination And Duration Dependence In A Semistructural Model, Ismail Baydur, Jianhuan Xu

Research Collection School Of Economics

This article develops a job-search model with unobserved worker heterogeneity and learning about worker types from unemployment duration. The model features negative duration dependence that stems from unobserved heterogeneity, skill depreciation, and statistical discrimination. We estimate job-finding rates implied by our model using microlevel data from the Current Population Survey. We find that removing interview costs counterfactually, thereby eliminating statistical discrimination, substantially increases the job-finding rates of the long-term unemployed. The performance of low-skill workers at the interview stage with discriminating firms plays a key role in explaining our counterfactual result.

The Classification Paradox: Historically Black Colleges' And Universities' Complex Relationship With Inequitable Experiences With The Carnegie Classification System, Felecia Commodore

Educational Leadership & Workforce Development Faculty Publications

[Introduction] Higher education in the United States boasts of diverse institutional offerings to students. From community colleges to well-resourced liberal arts institutions, this diverse array of institutions and types has created a system commonly viewed as having a variety of access points for those seeking higher learning. Higher education stakeholders can argue that this diversity is a strong suit of American higher education, but an argument can also be made that this same institutional diversity laid the groundwork for systemic racism and inequities within the higher education system.

These inequities exist through various intersecting systems and practices, such as the …

“Fly Buddha To Mars”: The Co-Production Between Religiosity And Science & Technology At Longquan Monastery, Beijing, Han Zhang, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This article attempts at a re-theorization towards the symbiosis and co-production of religion, modern science and technology, inspired by theoretical thinking within geographies of religion and science and technology studies (STS). Recent scholarship on the geographies of religion has made substantive advancements in discerning the convergence of religion and secular modernity. However, science and technology (S&T), as an essential condition and driving force of secular modernity, remain peripheral to this ongoing theoretical agenda, yet to be fully incorporated into the analytical framework about the co-constitution of religion and secular modernity, arguably because of the entrench divide between the rationalism of …

Lion City Zoopolis: Urban Crittizenship In Biophilic Singapore, George Wong

Research Collection School of Social Sciences

A central theme of Singapore’s “City in Nature” vision is framed through biophilic urbanism, or efforts to harmonize biodiversity and urban development through built, social, and political design. The central discourses of Singapore’s biophilic urbanism have revolved around flora-centric paradigms, including habitat conservation, greening spaces, and access to natural capital. This paper detours from conventions of Singapore’s urban ecological futures and instead explores the governance of fauna co- existence in the city–state through the concept of “urban crittizenship.” Defined as a more-than-human denization framework that interrogates urban wildlife governance, urban crittizenship interrogates the politics of urban wildlife’s rights to the …

On The Optimal Forecast With The Fractional Brownian Motion, Xiaohu Wang, Jun Yu, Chen Zhang

Research Collection School Of Economics

This paper investigates the performance of different forecasting formulas with fractional Brownian motion based on discrete and finite samples. Existing literature presents two formulas for generating optimal forecasts when continuous records are available. One formula relies on a history over an infinite past, while the other is designed for a record limited to a finite past. In reality, only observations at discrete time points over a finite past are available. In this case, the forecasting formula, which has been widely used in the literature, is the one obtained by Gatheral et al. (2018) that truncates and discretizes the formula based …

A literature review was conducted, which informed questions that were asked in an interview setting. Interviews were conducted with leaders that identify as women in higher education and sought to provide personalized accounts of the researched trends. Ultimately, despite higher education being perceived as a progressive industry and having legislature in place to combat gender disparities, leadership positions are not reflective of gender distribution …

A Novel Dual Configuration Dart/Uhplc-Ms/Ms System For The Rapid Analysis Of Psilocybin-Containing Mushrooms And Other Seized-Drug Submissions, Aron R. Jaffe

Master of Science in Forensic Science Directed Research Projects

The use and availability of controlled substances is highly dynamic. When a classical or novel psychoactive substance becomes popular, an influx of seized-drug evidence submissions closely follows, contributing to an ever-growing backlog of exhibits awaiting identification. The need for inclusive, rapid, and robust analytical methods is apparent, as demonstrated by recent growth in hallucinogen use. Psilocybin and psilocin, among other entheogens, have become increasingly popular and an increase of psilocybin mushroom seizures by law enforcement has followed. The structural similarity and thermal lability of many entheogens preclude their identification using many conventional analysis techniques. A DART and UHPLC were interchangeably …

Challenges In Diagnosing Adhd: Discrepancies Between Behavioral And Executive Functioning Indicators, Amneet Kaur

Selected Full Text Dissertations, 2011-

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, hyperactivity, impulsivity, and executive function deficits. The DSM-5-TR (American Psychiatric Association [APA], 2022), along with the DSM IV-TR (APA, 2000) and the DSM-5 (APA, 2013), emphasizes the behavioral aspects of ADHD while giving scant attention to executive function deficits, complicating diagnosis for clinicians and potentially resulting in misdiagnosis. This study seeks to identify the prevalence of ADHD diagnoses based on psychological evaluations where data from behavioral rating scales meet DSM criteria, but data from executive functioning measures do not, suggesting potential misdiagnosis. In this descriptive mixed design content …
