    Writing a Wikipedia Article on Cultural Competence in Health Care

    No full text
    This article describes how librarians created a Wikipedia article on cultural competence in health care to support the medical school’s curriculum. Wikipedia, often considered not as reliable as scholarly articles, continues to be popular. Rutgers librarians conducted a Wikipedia project to improve its content to benefit students. The importance of cultural competency in health care is widely recognized due to increasingly diverse patient populations. Medical schools integrate cultural competency in curricula to train students to be culturally competent. Therefore, this topic was chosen for the Wikipedia Project. It is hoped that health sciences librarians and educators will benefit from their experience

    Calabi–Yau threefolds and moduli of abelian surfaces I

    Get PDF
    We describe birational models and decide the rationality/unirationality of moduli spaces A\cal Ad (and A\cal Alevd) of (1, d)-polarized Abelian surfaces (with canonical level structure, respectively) for small values of d. The projective lines identified in the rational/unirational moduli spaces correspond to pencils of Abelian surfaces traced on nodal threefolds living naturally in the corresponding ambient projective spaces, and whose small resolutions are new Calabi–Yau threefolds with Euler characteristic zero

    Graphs with Lin-Lu-Yau curvature at least one and regular bone-idle graphs

    We study the Ollivier-Ricci curvature and its modification introduced by Lin, Lu, and Yau on graphs. We provide a complete characterization of all graphs with Lin-Lu-Yau curvature at least one. We then explore the relationship between the Lin-Lu-Yau curvature and the Ollivier-Ricci curvature with vanishing idleness on regular graphs. An exact formula for the difference between these two curvature notions is established, along with an equality condition. This condition allows us to characterize edges that are bone-idle in regular graphs. Furthermore, we demonstrate the non-existence of 3-regular bone-idle graphs and present a complete characterization of all 4-regular bone-idle graphs. We also show that there exist no 5-regular bone-idle graphs that are symmetric or a Cartesian product of a 3-regular and a 2-regular graph.23 pages, 5 figures. arXiv admin note: substantial text overlap with arXiv:2407.0885

    Outerplanar graphs with positive Lin–Lu–Yau curvature

    No full text
    In this paper, we show that all simple outerplanar graphs G with minimum degree at least 2 and positive Lin–Lu–Yau Ricci curvature on every edge have maximum degree at most 9. Furthermore, if G is maximally outerplanar, then G has at most 10 vertices. Both upper bounds are sharp.</p
