Definitions And Mathematical Models Of Op Variants, Pieter Vansteenwegen, Aldy Gunawan

Research Collection School Of Computing and Information Systems

We have described the basic orienteering problem (OP) in Chap. 2, as one known variant of the single vehicle routing problems with profits (VRPP). In this chapter, we introduce the best-known variants of the OP. The first one is the team orienteering problem (TOP). In the TOP multiple routes can be composed to visit a subset of customers. In the context of the game of orienteering, the TOP corresponds to several players of the same team, each collecting profits in parallel, during the same time span. Another well-known variant of the basic OP is the OP with time windows (OPTW), …

The Joint Effect Of Bilingualism And Sleep On Executive Functions Among Children And Adolescents With Attention Deficit/Hyperactivity Disorder (Adhd), Yirou Jiang

Doctoral Dissertations

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that significantly impacts cognitive and behavioral functions, leading challenges for individuals across the lifespan. While extensive research has been conducted to understand the connection between executive functioning (EF) and ADHD, research findings related to the contributing factors of bilingualism and sleep still remains inconsistent (Bialystok et al., 2017). Investigating the joint effect between bilingualism and sleep on EF among children and adolescents with ADHD may help further clarify the connection between EF, language, and sleep, and facilitate the development of interventions from the perspective of these protective factors. EF encompasses cognitive processes …

Navigating Undone Science: The Search For Adequate Endometriosis Care, Heather Welty, Melanie Jeske

Center for Medical Ethics and Health Policy Staff Publications

Endometriosis is an estrogen-dependent disease in which tissue similar to the lining of the uterus grows elsewhere in the body leading to a variety of symptoms including heavy and prolonged menstruation, chronic pain, cysts, infertility, and gastrointestinal issues. Despite being one of the most common gynecologic conditions, much remains unknown about potential risk factors for endometriosis, its etiology, and treatment options. First and second-line biomedical treatment options, complementary and alternative medicine, and lifestyle changes are all treatment options that people living with endometriosis (PLE) leverage to manage their symptoms. This article draws on in-depth interviews with 52 people living with …

This trial evaluated the efficacy of DiaBetter Together, a 12-month strengths-based behavioral intervention delivered by trained peer mentors. The intervention aimed to help young adults navigate the transfer process to promote optimal glycemic outcomes, shorten time to adult care follow-up, and improve psychosocial outcomes.

Research design and methods: Using a single-site randomized clinical trial design, we compared the 12-month intervention to usual care among n = 100 young adults aged 17-25 years …

“We Want To Make You A Better Man”: African American Men With Dual Membership In Black Greek Letter Organizations And Prince Hall Masonic Lodges, Lakesha Rae Denton

All-Inclusive List of Electronic Theses and Dissertations

This dissertation examines the rationale and experiences of Black men who have initial membership within a black Greek letter organization as an undergraduate, who also join Masonic Lodges. The study was guided by one research question: 1) what the rationale is pertaining to Black men, who are initially members of Black Greek letter organizations as an undergraduate, that also join a Masonic lodge, therefore granting them dual membership status. The study was important because the value of BGLO’s has declined due to hazing and lack of leadership and guidance. Black men are not being developed as they should and while …

Neurotypical And Neurodivergent Traits As Predictors Of Memory Performance, Maranda N. Willis

Electronic Theses and Dissertations

Traits associated with autism spectrum disorder (ASD) have been observed within neurotypical populations to influence a range of cognitive and behavioral characteristics, including attention to detail and the need for cognition (NC). The present study assessed traits commonly associated with ASD with the 42-item Comprehensive Autistic Trait Inventory (CATI) for 111 participants. The relations between ASD-like traits, attention to detail, as afforded by the Minnesota Clerical Aptitude Test (MCT), and memory, as measured by vignettes, were examined. Memory performance was assessed using 12 multiple-choice questions on vignette details. Participants read one of three randomly assigned 25-sentence vignettes of varying themes …

Semiparametric Cointegrating Rank Selection For Curved Cross-Section Time Series, Peter C. B. Phillips

Research Collection School Of Economics

Cointegrating rank selection is studied in a function space reduced rank regression where the data are time series of cross-section curves. Consistent cointegrating rank estimation is developed using information criteria extended to curve time series environments. The asymptotic theory involves two-parameter Gaussian processes that generalise the standard limit processes involved in cointegrating regressions. Simulations provide evidence of the effectiveness of consistent rank selection by the BIC criterion and the tendency of AIC to overestimate order as in standard lag order selection in autoregression, as well as in reduced rank regression with multiple time series.

Connectivity And Selective Rural Migration, Lin Ma, Yuan Mei, Qunfeng Wu, Mingzhi Xu

Research Collection School Of Economics

How does infrastructure shape rural development? Using household panel data from a nationally representative sample of Chinese villages, matched to high-resolution highway maps, we find that road expansion between 2000 and 2015 operates mainly through reallocation, with less productive farmers scaling down or exiting and more productive farmers remaining and expanding. We quantify the aggregate and distributional consequences in a dynamic spatial equilibrium model with heterogeneous households and endogenous migration. Improved connectivity not only accelerates urbanization but also increases aggregate rural output by 2.2%–5.3% in the long run, even as the rural workforce declines.

Singapore In Global Value Chains: Implications Of The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen

Research Collection School Of Economics

This paper examines Singapore’s structural position in global value chains (GVCs) and the implications of the second Trump administration’s tariff escalation for Singapore and the broader ASEAN region. We proceed in three parts. First, using the ADB Multi-Regional Input–Output (MRIO) tables for 2019 and 2024, we characterise Singapore’s GVC participation and position. Singapore is the most GVCintensive economy in ASEAN, with nearly half of its gross exports comprising foreign value-added and a markedly downstream orientation. China is its dominant upstream partner across manufacturing and services—intermediating over 27% of foreign content in electronics and over 10% in chemicals—while Malaysia, Taiwan, and …

Marital Stability And Intrahousehold Inequality, Tomoki Fujii, Xirong Lin, Jacob Penglase

Research Collection School Of Economics

We study what predicts marital instability using a unique dataset from Japan with detailed measures of spouses’ consumption, savings, labor supply, satisfaction, and marriage-market conditions. We combine descriptive survival and event-study analyses with several econometric and machine-learning approaches, including Cox proportional-hazards models and DynForest, a method designed for survival data with time-varying covariates. Across these approaches, match quality, household resources, time use, stated satisfaction, and marriage-market conditions all contain predictive information. Our main contribution is to show that intrahousehold consumption allocation matters, highlighting information that is missed by standard demographic, time use, and income measures. We relate these findings to …

The Interplay Of Interdependence And Correlation In Bilateral Trade, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

Following Crémer and McLean (1985, 1988) for finite type spaces and McAfee and Reny (1992) for continuous ones, we establish two respective sufficient conditions for the existence of efficient, ex ante budget-balanced mechanisms satisfying Bayesian incentive compatibility (BIC) and interim individual rationality (IIR) in bilateral trade settings with interdependent values and correlated beliefs. We then utilize the ex ante welfare (EAW) condition proposed by Kunimoto and Zhang (2026), which is necessary for the stricter requirement of ex post budget balance. We prove that while the EAW condition is sufficient in a two-type model and generalizes existing conditions in the literature, …

Dynamics Of High-Growth Young Firms And The Role Of Venture Capitalists, Yoshiki Ando

Research Collection School Of Economics

Motivated by the substantial growth and upfront investments of venture capital (VC)-backed firms observed in administrative US Census data, this study develops a life-cycle firm dynamics model. In the model, startups choose the source of financing from VC, angel investors, or banks, depending on their growth potential, and invest in innovation. The calibrated model explains the life-cycle dynamics of firms with different sources of financing and suggests that venture capitalists' managerial advice accounts for around 22% of the growth in VC-backed firms. A counterfactual economy without VC financing would experience an aggregate consumption loss of around 0.46%.

From Open Banking To Banking-As-A-Service: Regulatory Challenges In The Evolution Of Financial Intermediation, Nydia Remolina Leon

Research Collection Yong Pung How School Of Law

Over the past decade, financial innovation has moved from open banking, centred on consumer-permissioned data sharing, to banking-as-a-service (BaaS), which modularises core banking functions through application programming interfaces. This shift allows fintechs and non-financial platforms to embed financial products seamlessly, reducing transaction costs and fostering innovation. Yet the 2024 collapse of Synapse in the United States exposed the fragility of this model when intermediaries operate outside robust oversight, leaving consumers without recourse and revealing liability fragmentation and regulatory blind spots. This paper distinguishes BaaS from open banking, open finance, and embedded finance, and maps leading global models – from bank-led …

Piracy, Terrorism, And The Law: Differential Equations In Hostage Situations, Gabriel Hallevy

Journal of Humanistic Mathematics

Pirates have taken the crew of an American ship hostage. They promise to release the hostages only if another pirate who is held in an American prison for commission of piracy crimes against American citizens, is released. Should the U.S. government enter into negotiations with them? Should they send armed forces and risk the hostages? Should they release the prisoner immediately and unconditionally? The article models and analyzes possible policies regarding sensitive situations involving hostages and other related risks using differential equations. The solutions are surprisingly simple, but not necessarily intuitive. Our analysis aims to demonstrate how powerful mathematics is …

A Systematized Review Of The Effectiveness Of Sbirt On Reducing Adolescent Substance Use In School Settings, Mallory L. Mcivor

Educational Specialist, 2020-current

As substance use remains a pressing public concern for adolescents, the academic, social, and neurological consequences are extensive. Schools are uniquely situated to support large populations of youth during their critical developmental periods, and schools act as the ideal location for substance use prevention and intervention. This study explored the prevalence and influence of substance use on adolescents, the role of school climate in prevention and intervention efforts, and assessed the model Screening, Brief Intervention, and Referral to Treatment (SBIRT) as a suitable framework for school-based interventions. Following a structured search across two databases, 20 studies met inclusion criteria and …

Housing Precarity Among Marginalized Women In Neoliberal Contexts: A Systematic Literature Review, Faza Nur Syahida, Joko Adianto

Journal of Strategic and Global Studies

This study presents a Systematic Literature Review (SLR) investigating the lived experiences of women from vulnerable groups in securing access to housing within the ideological contours of neoliberal capitalism. The inquiry delves into the layers of exclusion, precarity, and structural silencing that frame their trajectories. The study identifies five intersecting identities among vulnerable women: (1) single women; (2) single mothers; (3) survivors of gender-based violence; (4) elderly women; and (5) migrant women laborers. Through a rigorous database search guided by predetermined selection criteria, fifteen scholarly articles were selected for review. These were organized into the five categories, each containing two …

Systematic Review Of The Institutionalization Of Service Learning In Higher Education, Wilmer Hernan Cruz Gutierrez

ASEAN Journal of Community Engagement

An increasing number of universities are integrating service-learning (SL) to fulfill their social mission. However, sustainable institutionalization of SL remains a persistent challenge. This study identifies and analyzes the factors, actors, and strategies that drive and inhibit SL institutionalization in higher education. Using the PRISMA 2020 guidelines, a systematic literature review analyzed 52 documents from seven academic databases (including WoS, Scopus, and ERIC). The findings were grouped into three sections: cultural (integration into institutional values/missions), process (articulation within teaching, research, and outreach), and structural dimensions (dedicated support entities). The results obtained reveal a reciprocal relationship where cultural alignment enables processual …

Online Mindfulness Training And Work-Related Outcomes: A Randomized Waitlist Controlled Trial, Conner Lee Deichman

Theses and Dissertations

Mindfulness-based interventions improve employee well-being, yet few studies have examined their impact on work-specific outcomes in private-sector samples. Online mindfulness programs offer a promising, accessible alternative to in-person training. This randomized waitlist-controlled trial evaluated the efficacy of Mindfulness for Humans (MfH), a fully online, self-directed 15-session program, on job satisfaction, burnout, work engagement, subjective well-being, and mindfulness skills among private-sector employees. Participants were randomly assigned to a training-first group or a waitlist-first group and completed measures at baseline, 30 days, and 60 days. Results showed significant improvements in job satisfaction, burnout, subjective well-being, and mindfulness following course participation. The training-first …

Belonging's Influence On Volunteer Motivation In Faith-Based Nonprofit Organizations: An Interpretative Phenomenological Analysis, Adam Stockton

Journal of Nonprofit Innovation

Nonprofit organizations often overlook psychological belonging as a driver of volunteer retention and recruitment (Hurt, 2025; Mochin, 2022). The purpose of this qualitative Interpretative Phenomenological Analysis (IPA) study was to explore how a sense of belonging influenced the intrinsic motivation of nine adults volunteering with a faith-based nonprofit organization in the southern United States. Data were collected through semi-structured interviews and analyzed using IPA best practices to identify themes from participants' experiences. The study was grounded in Maslow's Hierarchy of Needs, self-determination theory, and organizational identification theory—frameworks that describe how individuals connect personal values and identity to the values and …

Building Adaptive Capacity In Community Engaged Nonprofits, Lena Hatchett, Kenneth E. Steinkruger, Laundette P. Jones

Journal of Nonprofit Innovation

Nonprofit organizations face ongoing challenges related to uncertain funding, staff burnout, and increasing community needs. This article describes adaptive capacity as a proactive form of resilience that can help nonprofits prepare for unexpected challenges before they occur.  Drawing on examples from a small community-engaged nonprofit, the current article presented activities and tools for strengthening adaptive capacity through both longer-term capacity-building practices and everyday organizational decisions.  We used the McKinsey 7S framework to organize adaptive capacity opportunities across strategy, structure, systems, shared values, skills, style, and staff.  The examples suggest that, despite unanticipated challenges, community-engaged nonprofits may strengthen resilience by adopting …
