Energy Islands: Metaphors Of Power, Extractivism, And Justice In Puerto Rico, Catalina M. De Onís

University of Montana Staff Publications

Energy Islands provides an urgent and nuanced portrait of collective action that resists racial capitalism, colonialism, and climate disruption. Weaving together historical and ethnographic research, Catalina M. de Onís challenges the master narratives of Puerto Rico as a tourist destination and site of “natural” disasters. She demonstrates how fossil-fuel economies are inextricably entwined with colonial practices and policies and how local community groups in Puerto Rico have struggled against energy coloniality and energy privilege to mobilize and transform power from the ground up. This work decenters continental contexts and deconstructs damaging hierarchies that devalue and exploit disenfranchised rural, coastal communities. …

A Formal Justification Of The Ancient Chinese Method Of Computing Square Roots, Edilberto Najera, Leslie Cristina Najera-Benitez

The Mathematics Enthusiast

In this paper a formal justification of the ancient Chinese method for computing square roots is given. As a result, some already known properties of the square root which is computed with this method are deduced. If any other number base is used, the justification given shows that the method is applied in the same way and that the deduced properties are still being fulfilled, facts that highlight the importance of positional number systems. It also shows how to generalize the method to compute high orders roots. Although with this elementary method you can compute the square root of any …

Squaring The Circle And Doubling The Cube In Space-Time, Espen Gaarder Haug

The Mathematics Enthusiast

Squaring the Circle is a famous geometry problem going all the way back to the ancient Greeks. It is the great quest of constructing a square with the same area as a circle using a compass and straightedge in a finite number of steps. Since it was proven that ⇡ was a transcendental number in 1882, the task of Squaring the Circle has been considered impossible. Here, we will show it is possible to Square the Circle in space-time. It is not possible to Square the Circle in Euclidean space alone, but it is fully possible in space-time, and after …

Indigenous Culture-Based School Mathematics In Action: Part I: Professional Development For Creating Teaching Materials, Sharon Meyer, Glen Aikenhead

The Mathematics Enthusiast

This first of a pair of articles describes a professional development project that prepared four non-Indigenous mathematics teachers (Grades 5-12) to implement Canada’s Truth and Reconciliation Commission’s (TRC, 2016) notion of reconciliation: cross-cultural respect through mutual understanding. The researchers collaboratively mentored the teachers to enhance their mathematics teaching with Indigenous mathematizing3. The teachers’ focus was on developing and revising lesson plans for other teachers to teach. This process explicitly and implicitly revealed precise supports that need to be in place for a teacher to succeed at innovating with this Indigenous culture-based school mathematics (ICBSM). Part I is a template for …

The Suuji Approach To Multi-Digit Addition: Using Length To Deepen Students’ Understanding Of The Base 10 Number System, Ryota Matsuura, Olaf Hall-Holt, Nancy Dennis, Michelle Martin, Sarah Sword

The Mathematics Enthusiast

We describe the Suuji representation of numbers which aims to deepen elementary students’ understanding of the base 10 system. (“Suuji” means “number” in Japanese.) This representation takes a two pronged approach of (1) making the place value more explicit and (2) using length to represent numbers, thus allowing students to reason spatially. We taught multi-digit addition using the Suuji representation to 20 second and third grade students. The article uses lesson descriptions and student work to illustrate the Suuji approach, as well as its impact on student learning.

Using Records Of Practice To Bridge From Teachers’ Mathematical Problem Solving To Classroom Practice, Davida D. Fischman, Iris M. Riggs

The Mathematics Enthusiast

It is often the case that high quality mathematics education professional development involves enhancing both teachers’ content knowledge and their pedagogical skills, specifically for teaching mathematics. However, when teachers are immersed in their own learning of mathematics, they are often unaware of the facilitators’ instructional decisions and moves that influence their own learning outcomes, as well as how these might apply to their future teaching. Thus, while the teachers can appreciate their new understanding of content, they may not have added significantly to their understanding of the instructor’s pedagogical moves that facilitated their growth. As a result, teachers may leave …

Dancesport And Power Values, Diana Cheng, Peter Coughlin

The Mathematics Enthusiast

DanceSport is a competitive form of ballroom dancing. At a DanceSport event, couples perform multiple dances in front of judges. This paper shows how a goal for a couple and the judges' evaluations of the couple's dance performances can be used to formulate a weighted simple game. We explain why couples and their coaches may consider a variety of goals. We also show how prominent power values can be used to measure the contributions of dance performances to achieving certain goals. As part of our analysis, we develop novel visual representations of the Banzhaf and Shapley-Shubik index profiles for different …

The Structure Of The Cysteine-Rich Region From Human Histone-Lysine N-Methyltransferase Ehmt2 (G9a), Keshia M. Kerchner, Tung-Chung Mou, Yizhi Sun, Domniţa-Valeria Rusnac, Stephen R. Sprang, Klára Briknarová

Biological Sciences Faculty Publications

Euchromatic histone-lysine N-methyltransferase 1 (EHMT1; G9a-like protein; GLP) and euchromatic histone-lysine N-methyltransferase 2 (EHMT2; G9a) are protein lysine methyltransferases that regulate gene expression and are essential for development and the ability of organisms to change and adapt. In addition to ankyrin repeats and the catalytic SET domain, the EHMT proteins contain a unique cysteine-rich region (CRR) that mediates protein-protein interactions and recruitment of the methyltransferases to specific sites in chromatin. We have determined the structure of the CRR from human EHMT2 by X-ray crystallography and show that the CRR adopts an unusual compact fold with four bound zinc atoms. The …

Flattening The Curve, Peter Zizler, Mandana Sobhanzadeh

The Mathematics Enthusiast

We quantify flattening the curve under the assumption of a soft quarantine in the spread of a contagious viral disease in a society. In particular, the maximum daily infection rate is expected to drop by twice the percentage drop in the virus reproduction number. The same percentage drop is expected for the maximum daily hospitalization or fatality rate. A formula for the expected maximum daily fatality rate is given.

Utilizing Suicide Death Certificates To Evaluate Suicide Prevention Programs: A Descriptive And Ecological Study, Nathan A. Munn

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Objective: Suicide rates continue to increase despite various suicide prevention efforts. This study’s objective is to examine suicides in the State of Montana to ascertain suicide decedents’ demographics and the effectiveness of interventions to guide future prevention programs.

Method: Data from 1,665 suicide decedents’ death certificates were analyzed for age, ethnicity, veteran status, gender, education level, and means of suicide. Four types of suicide prevention strategies were examined for association with regional suicide rates: psychotherapist concentration, gatekeeper training, presence of county public health suicide prevention programs, and pre- post-implementation of statewide public service announcements.

Results: Compared with the general Montana …

The Works Of Omar Khayyam In The History Of Mathematics, Thomas Bisom

The Mathematics Enthusiast

The exact time when the mathematician Omar Khayyam lived is not well-defined, but it is generally agreed upon that he lived from the end of the 11th century to the beginning of the 12th century C.E. in Nishapur, which is in modern-day Iran and Afghanistan (Struik, 1958). Other than mathematics, Omar Khayyam also made considerable contributions to other fields, such as astronomy, philosophy, and poetry (Struik, 1958). He is probably most famous for his poem titled Rubaiyat of Omar Khayyam, which was translated by Edward Fitzgerald (Struik, 1958). Although famous for his poetry, he was professionally inclined to astronomy and …

This study uses a qualitative Phenomenology to investigate and describe the experiences of female fighter pilots in the United States Air Force. Several important findings emerged from the study including: the impact of the population’s minority status on their experience; the pervasiveness and impact of systemic sexism, institutional betrayal, sexual assault, ambivalent sexism, and pregnancy discrimination; details of utilized resiliency skills; the prevalence of burnout; …

Protecting Life And Lung: Protected Areas Affect Fine Particulate Matter And Respiratory Hospitalizations In The Brazilian Amazon Biome., Derek Michael Sheehan

Graduate Student Theses, Dissertations, & Professional Papers

I assessed the impacts of upwind protected area coverage on local respiratory health within the Brazilian Amazon. A hypothesized mechanism is the legal prohibition of human ignited fires within protected areas, reducing particulate matter pollution, impacting respiratory health downwind. The connection between fires and respiratory diseases in the Amazon is well established (Smith et al. 2014; Rangel and Vogl 2019; Rocha and Sant’anna 2020). What is not well understood is the potential that government policies aimed at preventing ecosystem loss may also promote health and wellbeing, combining the UN sustainable development goals 3 and 15. Protected areas currently dominate government …
