Peter Flom was inspired to write this blog post after visiting the Kaplans' Math Circle in Boston.

The Sunday Math Circle, Nathan Pflueger

Journal of Math Circles

Bob and Ellen Kaplan envisioned and organized a style of math circle centered on the idea that children of all ages can work like mathematicians do: creatively, collaboratively, and ecstatically. This article surveys four sample topics covered during a Sunday morning math circle in the Boston area, based on Bob and Ellen's invaluable guidance. I also offer some reflections on what I learned from Bob and Ellen, and how it is reflected in these math circles.

Introduction To The Special Issue Honoring Bob And Ellen Kaplan, Amanda Serenevy, Rodi Steinig

Journal of Math Circles

In 1994, Bob and Ellen Kaplan embarked together with other friends and colleagues on a wonderful adventure. Friends had lamented that there was a lack of high-quality math learning experiences for kids along the lines of the Math Circles offered in the former Soviet Union, so the Kaplans decided to do something about it. This special issue is dedicated to a remembrance of that adventure and its impact on the mathematical and personal development of many people.

Sheep Umbilical Cord Mesenchymal Stem Cells: Biological Characteristics, Ethical Considerations, And Translational Applications, Hasan M. Agha, Mohammed A. Abdalqader, Oh Chin Kin Michelle, Sabaa M. Agha, Jantson Hoh, Abdulmutalib Alabeed Allaq, Amjad Abdulhadi Mohammed, Muneer Mohammed Saleh Alsayadi

AUIQ Complementary Biological System

Mesenchymal stem cells (MSCs) are widely used in regenerative medicine due to their self-renewal capacity, multilineage differentiation potential, and paracrine activity. Limitations associated with the sourcing and scalability of human MSCs have increased interest in xenogeneic alternatives, particularly sheep umbilical cord–derived MSCs (sUC-MSCs). These cells display high proliferative capacity, stable karyotypes, and a typical MSC immunophenotype (CD44, CD73, CD90, CD105), with low basal immunogenicity. sUC-MSCs exhibit osteogenic, chondrogenic, and adipogenic differentiation potential and secrete angiogenic and immunomodulatory factors, including VEGF, HGF, IGF-1, TGF-β, and IL-10. Owing to their biological similarities to human MSCs and accessibility from perinatal tissue, …

Strategic Distribution, Digital Marketing, And Open Innovation: Toward Integrated Capability Development For Sme Performance, Johannes Baptista Halik, Maria Yessica Halik, Septin Basongan, Jhoel Mapau

Asia Marketing Journal

This study examines the impact of Distribution Strategy on SME performance, with Digital Marketing and Open Innovation as mediating variables. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), data were analyzed from 250 SMEs in Makassar, Indonesia. The results show that Distribution Strategy positively affects performance, both directly and indirectly through Open Innovation. However, Digital Marketing does not serve as a significant mediator, indicating that its use among SMEs may still be limited to tactical functions. Open Innovation emerges as the strongest contributor, highlighting its role in converting distribution capabilities into performance gains. The study enriches Resource Advantage (R-A) Theory …

Mitigating Appearance Threats: The Differential Effects Of Compensatory Consumption On Self-Control, Yi-Seo Jo, Eunice Eun-Sil Kim

Asia Marketing Journal

Appearance threats, arising from gaps between one’s appearance and societal beauty standards, weaken self-control the capacity to favor long-term goals over immediate impulses. This research explores how compensatory consumption mitigates these effects, focusing on type (within-domain vs. across-domain) and timing (near-future vs. distant-future) across two studies. Rooted in symbolic self-completion and construal level theories, Study 1 examines how compensation type affects self-control under appearance threats, with rumination as a mediator. Findings show across-domain compensation sustains self-control by diverting focus from appearance concerns, unlike within-domain compensation, which heightens rumination and impairs self-regulation. Study 2 investigates how compensation timing moderates these outcomes, …

When And Why Managerial Responseswork: A Dual-Process Model Of Linguistic Cues, Review Rating, And Usefulness, Jungwon Lee, Cheol Park

Asia Marketing Journal

This research develops and empirically tests a contingency model explaining how specific linguistic characteristics of a firm's response to an online review influence the review's usefulness. We argue that the diagnostic value of different linguistic cues is contingent upon the reader's information processing mode-systematic versus heuristic-which is triggered by the valence of the original review's rating. An econometric analysis of 41,704 review-response dyads from TripAdvisor reveals that a conceptual cue (personalization, operationalized as topical relevance) and a perceptual cue (readability) both significantly increase review usefulness. In contrast, another perceptual cue (Linguistic Style Matching) decreases usefulness, a finding we interpret as …

“It’S A Dupe, Not A Counterfeit!” An Exploration Of Motives For Dupe Consumption Motives, Jungyong Ahn

Asia Marketing Journal

This study was designed to explore consumer motives for dupe consumption and to measure the influence of these identified motives on consumer satisfaction with dupe products and intention to sharing dupe products. Through a literature review and in-depth interviews, five key consumer motives were anticipated: (1) self-protection, (2) saving money, (3) anti-materialism, (4) mimicry, and (5) enjoyment. Corresponding measurement items were developed to assess these motives. A factor analysis conducted on survey data collected from 300 respondents successfully confirmed the extraction of these five motives as expected. Moreover, regression analysis further demonstrated the statistically significant positive impact of these motives …

How Does A Consumer’S Anticipated Happiness Influence Participation In Value Co-Creation? : Focusing On Definition Of Happiness, Minsik Cho, Suna La

Asia Marketing Journal

Value co-creation (VCC) is essential for a new product development, transforming ideas into collaboratively created value-in-use, particularly under Service-Dominant Logic (S-D Logic). Recognizing that consumers engage in VCC with the goal of achieving happiness, this study investigates how anticipated happiness—arising from affective forecasting of VCC experiences—encourages customers’ participation in high-technology VCC initiatives. It also examines how individuals’ definitions of happiness—calmness vs. excitement—influence this process in VCC, using a validated temporal focus manipulation to induce these differing happiness orientations. Results indicate that future-focused individuals tend to define their happiness as excitement, while present-focused individuals associate it with calmness. Then, definitions of …

The Impact Of Sense Of Power On Consumer Click-Through Intention Under Ai Personalized Recommendation, Li Li, Dhakir Abbas Ali

Asia Marketing Journal

This study investigates how consumers' sense of power influences their click-through intentions in AI-driven personalized recommendation systems. While prior research has explored personalized marketings impact on consumer behavior, the role of perceived power remains understudied. Through scenario-based experiments, we find that a heightened sense of power enhances engagement with AI recommendations, with self-efficacy as a key mediator. However, this effect weakens when privacy concerns are high, highlighting privacy as a critical moderating factor. Specifically, empowered consumers are more likely to interact with AI recommendations, but only when privacy risks are minimal. These findings deepen our understanding of consumer-AI interactions, emphasizing …

Blockchain-Based Peer-To-Peer Renewable Energy Trading And Traceability Of Transmission And Distribution Losses, Amit Kumar Vishwakarma, Pratyush Kumar Patro, Adolf Acquaye, Raja Jayaraman, Khaled Salah

Industrial Engineering: Faculty & Staff Publications

In attempts to progress the transition towards decarbonizing energy systems and achieving sustainable development goals linked to energy, renewable energy sources (RES), which are decentrally deployed, are being widely promoted. However, RES are constrained by many barriers, some of which are technical in nature, such as energy losses. For instance, traditional peer-to-peer (P2P) trading systems have been used as a mechanism to advance RES because they offer a promising solution for decentralized energy trading without third-party intermediaries. However, it faces significant challenges, notably in accounting for energy losses during transmission and distribution, thus reducing overall system efficiency. We propose an …

Theses and Dissertations

Under Ceaușescu's 1980s Sistematizare program, Bucharest's Orthodox monasteries sustained sacred life through "negotiated resilience": ritual repetition and spatial adaptation under surveillance and constrained visibility. Văcărești, Mihai Vodă, and Antim map a spectrum—erasure, relocation/concealment, and institutional negotiation—complicating binaries of resistance and collaboration.

Retroactive Eligibility Waivers: Innovative Or Ineffective?, Mohamed Kacem Benyamine

Theses and Dissertations

Medicaid’s retroactive eligibility provision covers medical expenses for beneficiaries up to 90 days before the application date. Retroactive eligibility insulates uninsured, low-income households from expensive healthcare emergencies. New Hampshire, Arkansas, and Iowa recently obtained waivers to end retroactive coverage. Using a difference-in-differences design and data from the Behavioral Risk Factor Surveillance System, I evaluate whether changes in retroactive coverage affect enrollment rates and self-reported health. Removing retroactive eligibility has no statistically significant effects on insurance enrollment or self-reported health. However, it does increase rates of access to a doctor by 1.0% overall and by 1.6% for women. Removing retroactive eligibility …

Capturing The Spirit Of Childhood: An Analysis Of Robert Henri’S Portraits Of Children, Alex C. Maccaro

Theses and Dissertations

Robert Henri (1865-1929) is perhaps best known as the prominent leader of the turn-of-the century American movement The Eight, commonly known as “the Ashcan School,” and as a leading teacher in the United States during the early twentieth century. However, his artistic output as a portrait painter, particularly of children, is also significant. Beginning in 1904 and throughout his career as an artist, Henri painted hundreds of images of children in the various foreign or remote locales to which he traveled, often depicting the same subject in multiple instances. These portraits range from the roughly painted, rosy-cheeked Dutch youth of …
