Public Recognition And Media Coverage Of Mathematical Achievements, 2019 University of Alicante

#### Public Recognition And Media Coverage Of Mathematical Achievements, Juan Matías Sepulcre

*Journal of Humanistic Mathematics*

This report aims to convince readers that there are clear indications that society is increasingly taking a greater interest in science and particularly in mathematics, and thus society in general has come to recognise, through different awards, privileges, and distinctions, the work of many mathematicians. We provide examples of recognition accorded by institutions, societies, schools, communities, academies, and the public in general to these mathematicians.

Telling Women's Stories: A Resource For College Mathematics Instructors, 2019 University of Toronto

#### Telling Women's Stories: A Resource For College Mathematics Instructors, Sarah Mayes-Tang

*Journal of Humanistic Mathematics*

Stereotypes about mathematicians that conflict with ``traditionally feminine" identities are widely held by people from middle-school-age onwards, and can influence their participation in mathematics and related fields. Simply being exposed to women in mathematics is not enough to change students' perceptions of mathematicians, and may even decrease girls' interest in mathematics. This paper proposes a storytelling strategy to help change students' perceptions of mathematicians. It includes several activities for intentionally incorporating women's stories into the post-secondary classroom and a list of resources for finding existing powerful stories. The diverse stories of women mathematicians, including details of their personal lives ...

Using Hidden Markov Modeling For Biogeographical Ancestry Analysis, 2019 Claremont Colleges

#### Using Hidden Markov Modeling For Biogeographical Ancestry Analysis, Melvin R. Currie

*Journal of Humanistic Mathematics*

This paper describes a methodology for analyzing X-chromosome data to establish biogeographical contributions to the author’s X chromosome. We present an exposition of how Hidden Markov Modeling (HMM) can be used as a black box for ancestry analysis and focus on a set of conditions that are not universal but fairly common. The first condition is that the ancestral populations are drawn from regions that have had very little or no contact with each other since prehistoric times. The second condition is that the number of possible ancestral populations is small. In this analysis, we assume that the ancestral ...

Choose Your Own Adventure: An Analysis Of Interactive Gamebooks Using Graph Theory, 2019 Southwestern University

#### Choose Your Own Adventure: An Analysis Of Interactive Gamebooks Using Graph Theory, D'Andre Adams, Daniela Beckelhymer, Alison Marr

*Journal of Humanistic Mathematics*

"BEWARE and WARNING! This book is different from other books. You and YOU ALONE are in charge of what happens in this story." This is the captivating introduction to every book in the interactive novel series, *Choose Your Own Adventure (CYOA)*. Our project uses the mathematical field of graph theory to analyze forty books from the *CYOA *book series for ages 9-12. We first began by drawing the digraphs of each book. Then we analyzed these digraphs by collecting structural data such as longest path length (i.e. longest story length) and number of vertices with outdegree zero (i.e ...

Engaging Crisis: Immersive, Interdisciplinary Learning In Mathematics And Rhetoric, 2019 Bates College

#### Engaging Crisis: Immersive, Interdisciplinary Learning In Mathematics And Rhetoric, Meredith L. Greer, Stephanie Kelley-Romano

*Journal of Humanistic Mathematics*

This paper describes an interdisciplinary activity that crosses over between Mathematics and Rhetoric. The professors who created this activity both sought active-learning opportunities for their students, a sense of realism--even urgency--in what can otherwise be perceived as abstract material, and a meaningful liberal arts experience. Evidence of the power of this experience is seen in the media coverage, both from our college and from the *Portland Press Herald* newspaper. Both courses described in this paper are at the elective level, taken by majors or minors in their respective disciplines. Students have moderate to extensive backgrounds in their subject areas. However ...

Visual Teaching Of Geometry And The Origins Of 20th Century Abstract Art, 2019 DePaul University

#### Visual Teaching Of Geometry And The Origins Of 20th Century Abstract Art, Stephen Luecking

*Journal of Humanistic Mathematics*

As a group, the artists educated near the turn of the 19^{th} and 20^{th} centuries possessed greater mathematical knowledge than expected of artists today, especially regarding constructive skills in Euclidean geometry. Educational theory of the time stressed such skills for students in general, who needed these to enter the workplace of the time. Mathematics teaching then stressed the use of manipulatives, i.e., visual and interactive aids thought to better fix the student’s acquisition of mathematical skills. This visual training, especially in geometry, significantly affected the early development of abstraction in art. This paper presents examples of ...

Pure Psvd Approach To Sylvester-Type Quaternion Matrix Equations, 2019 Shanghai University

#### Pure Psvd Approach To Sylvester-Type Quaternion Matrix Equations, Zhuo-Heng He

*Electronic Journal of Linear Algebra*

In this paper, the pure product singular value decomposition (PSVD) for four quaternion matrices is given. The system of coupled Sylvester-type quaternion matrix equations with five unknowns $X_{i}A_{i}-B_{i}X_{i+1}=C_{i}$ is considered by using the PSVD approach, where $A_{i},B_{i},$ and $C_{i}$ are given quaternion matrices of compatible sizes $(i=1,2,3,4)$. Some necessary and sufficient conditions for the existence of a solution to this system are derived. Moreover, the general solution to this system is presented when it is solvable.

The Decay And Formation Of One-Dimensional Nonconservative Shocks, 2019 Portland State University

#### The Decay And Formation Of One-Dimensional Nonconservative Shocks, Marek Elźanowski, Marcelo Epstein

*Marek Z. Elźanowski*

The method of singular surfaces is used to obtain explicit conditions under which a one-dimensional acceleration wave develops into a shock when some dissipation mechanism is present. The conditions which secure the initial growth of the strong shock wave propagating into an undeformed nonlinear and dissipative medium are also derived. The analysis is pre- sented for a single balance law, one-dimensional elasticity, and the non- linear Maxwellian continuum.

Coloring Count Cones Of Planar Graphs, 2019 Charles University, Prague

#### Coloring Count Cones Of Planar Graphs, Zdenek Dvorak, Bernard Lidicky

*Bernard Lidický*

For a plane near-triangulation G with the outer face bounded by a cycle C, let n⋆G denote the function that to each 4-coloring ψ of C assigns the number of ways ψ extends to a 4-coloring of G. The block-count reducibility argument (which has been developed in connection with attempted proofs of the Four Color Theorem) is equivalent to the statement that the function n⋆G belongs to a certain cone in the space of all functions from 4-colorings of C to real numbers. We investigate the properties of this cone for |C|=5, formulate a conjecture strengthening the ...

Estimation Of Association Between A Longitudinal Marker And Interval-Censored Progression Times, 2019 Portland State University

#### Estimation Of Association Between A Longitudinal Marker And Interval-Censored Progression Times, Naghmeh Daneshi

*Dissertations and Theses*

In longitudinal studies, we observe the subjects who are likely to progress to a new state during the study time. For example, in clinical trials the stage of a progressing disease is recorded at each follow-up visit. The primary goal is to estimate the relationship between the attributes and the subject's progression state. In such studies, some subjects complete all their follow-up visits and their progression state are observed without any missingness. However, others miss their follow-up visits and when they come back, they learn that they have progressed to a new state. In this case, not only are ...

Comparing Design Ground Snow Load Prediction In Utah And Idaho, 2019 Utah State University

#### Comparing Design Ground Snow Load Prediction In Utah And Idaho, Brennan L. Bean, Marc Maguire, Yan Sun

*Mathematics and Statistics Faculty Publications*

Snow loads in the western United States are largely undefined due to complex geography and climates, leaving the individual states to publish detailed studies for their region, usually through the local Structural Engineers Association (SEAs). These associations are typically made up of engineers not formally trained to develop or evaluate spatial statistical methods for their regions and there is little guidance from ASCE 7. Furthermore, little has been written to compare the independently developed design ground snow load prediction methods used by various western states. This paper addresses this topic by comparing the accuracy of a variety of spatial methods ...

The thematic approach of the edited MAA Notes volume *Shifting Contexts, Stable Core: Advancing Quantitative Literacy in Higher Education* is that the “construct” of quantitative literacy is now fairly stable, but the contexts in which quantitative literacy is taught (and practiced) continue to change. Several chapters give the reader much to consider regarding what constitutes the foundation of this stable core and, relatedly, how quantitative literacy ...

Richard Nisbett. 2015. *Mindware: Tools for Smart Thinking.*(New York, NY: Farrar, Strauss, and Giroux). 336 pp. ISBN: 9780374536244

Nisbett, a psychologist, may not achieve his stated goal of teaching readers to “effortlessly” extend their common sense when it comes to quantitative analysis applied to everyday issues, but his critique of multiple regression analysis (MRA) in the middle chapters of *Mindware* is worth attention from, and contemplation by, the QL/QR and Numeracy community. While in at least one other source, Nisbett’s critique has been called a “crusade” against MRA, what he really advocates is that it not be ...

#### Quantitative Literacy And The Mathematical Association Of America In The 2000’S: Ql Subcommittee Of Cupm , Sigmaa Ql, And Maa Notes #70, Rick Gillman

*Numeracy*

This Roots and Seeds article is a partial history of the quantitative literacy movement in the Mathematical Association of America in the first decade of the 21st century. It focuses on the inclusion of QL in the MAA Committee on the Undergraduate Program in Mathematics’ *CUPM Curriculum Guidelines* (2004), the creation of the special interest group for MAA members (SIGMAA QL, 2004), and the work of that body in subsequent years, in particular, the MAA Notes #70, *Current Practices in Quantitative Literacy* (2006). I discuss some issues that were problematic in the QL movement in the MAA in those years ...

The Ultimatum Game: An Introduction To Quantitative Literacy In A Social Justice Context, 2019 Lafayette College

#### The Ultimatum Game: An Introduction To Quantitative Literacy In A Social Justice Context, Robert G. Root

*Numeracy*

The Ultimatum Game is a two-person, multiple-strategy game widely used in the experimental social sciences to demonstrate the human propensity for costly punishment in response to inequitable treatment. The game serves to provide quantitative evidence for a diversity of fairness norms across cultures. The play of the game and its interpretation offer nuanced views of the nature and importance of quantitative literacy. Its use in a writing seminar connecting quantitative literacy and social justice is described.
