description: This dissertation describes the development and application of a new mathematical model for simulating the progression of Plasmodium falciparum infections in individuals with no malarial acquired immunity. The model allows for stochastic simulation of asexual and sexual parasitemias as well as the onset of fever and human to mosquito infectivity on a daily time scale. The model components for the asexual and sexual stages were developed elsewhere but are here extended to allow for simulation of the full range of dynamics observed in a subset of malaria therapy patients. As a first application of the model, I calculate the human component of malarial R0, the basic reproductive number. I then compare this value to those from three other models and describe how this quantity can be used to model malaria transmission. The second application of the model incorporates the effects of drug treatment on progression of infection by utilizing modeled pharmacokinetic and pharmacodynamic properties of a variety of antimalarials. I utilize a stage specific proportional killing model for sexual stages, informed from recent in vitro data. The relationship of effect sizes to treatment coverage and type of treatment in both early and late treatment seeking settings is calculated. In the third chapter, I consider the economic and epidemiological ramifications of antimalarial and rapid diagnostic subsidization for malaria control. For the epidemiological modeling I utilize a semi-mechanistic model of the spread of drug resistance parameterized from historical malaria mortality data; for the economic model I consider the effect of rapid diagnostics on the intensive and extensive margins of antibiotics and antimalarials, as well as the benefits to improved targeting of both. I find that rapid diagnostic testing is justified given our baseline assumptions for areas with low proportions of malarious individuals among all treatment-seekers, but that caution is necessary before deployment worldwide. For antimalarial subsidization, we find that this is a cost-effective method for reducing mortality in developing countries, though efforts to delay the onset and slow the spread of resistance are urgently needed.

description: An estimate on the number of distinct relative periodic orbits around a stable relative equilibrium in a Hamiltonian system with continuous symmetry is given. This result constitutes a generalization to the Hamiltonian symmetric framework of a classical result by Weinstein and Moser on the existence of periodic orbits in the energy levels surrounding a stable equilibrium.The estimate obtained is very precise in the sense that it provides a lower bound for the number of relative periodic orbits at each prescribed energy and momentum values neighboring the stable relative equilibrium in question and with any prefixed (spatiotemporal) isotropy subgroup. Moreover, it is easily computable in particular examples. It is interesting to see how in our result the existence of non trivial relative periodic orbits requires (generic) conditions on the higher order terms of the Taylor expansion of the Hamiltonian function, in contrast with the purely quadratic requirements of the Weinstein--Moser Theorem, which emphasizes the highly non linear character of the relatively periodic dynamical objects.

description: In recent years, Mainland Chinese teams have been the dominant participants in the two COMAP-sponsored mathematical modeling competitions: the Mathematical Contest in Modeling (MCM) and the Interdisciplinary Contest in Modeling (ICM).
      This study examines five factors that lead to the Chinese teams' dramatic increase in participation rate and performance in the MCM and ICM: the Chinese government's support, pertinent organizations' efforts, support from initiators of Chinese mathematical modeling education and local resources, Chinese teams' preferences in selecting competition problems to solve, and influence from the Chinese National College Entrance Examination (NCEE).
      The data made clear that (1) the policy support provided by the Chinese government laid a solid foundation in popularizing mathematical modeling activities in China, especially in initial stages of the development of mathematical modeling activities. (2) Relevant organizations have been the main driving force behind the development of mathematical modeling activities in China. (3) Initiators of mathematical modeling education were the masterminds of Chinese mathematical modeling development; support from other local resources served as the foundation of mathematical modeling popularity in China. (4) Chinese teams have revealed a preference for discrete over continuous mathematical problems in the Mathematical Contest in Modeling. However, in general, the winning rates of these two problem types have been shown to be inversely related to their popularity  while discrete problems have traditionally had higher attempt rates, continuous problems enjoyed higher winning rates. (5) The NCEE mathematics examination seems to include mathematical application problems rather than actual mathematical modeling problems. Although the extent of NCEE influence on students' mathematical modeling ability is unclear, the content coverage suggests that students completing a high school mathematics curriculum should be able to apply what they learned to simplified real-world situations, and pose solutions to the simple models built in these situations. This focus laid a solid mathematics foundation for students' future study and application of mathematics.

description: Richard Feynman: "There is a most profound and beautiful question associated with the observed coupling constant, e - the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has been experimentally determined to be close to 0.08542455. (My physicist friends won't recognize this number, because they like to remember it as the inverse of its square: about 137.03597 with about an uncertainty of about 2 in the last decimal place. It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.) Immediately you would like to know where this number for a coupling comes from: is it related to pi or perhaps to the base of natural logarithms? Nobody knows. It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. You might say the "hand of G-d" wrote that number, and "we don't know how He pushed his pencil." We know what kind of a dance to do experimentally to measure this number very accurately, but we don't know what kind of dance to do on the computer to make this number come out, without putting it in secretly!" In this note, a "computational dance" from which this number emerges without any need to put it in secretly is identified...
Complicating the Narrative of Title IX: A Content Analysis of Young Adult Sports Literature and Media

Year: 2024

description: This study aims to analyze how literature contributes to youth understandings of Title IX of the Education Amendments of 1972 and its impact on sports. Prior research notes that sports literature for youth and young adults contributes to simplistic understandings of access and athlete identity. This study elaborates by prioritizing nuance through the highlighting of newly released titles, and positions them in conversation with current counter-narratives, both socially and legally, around Title IX. Using a coding rubric, a content analysis was conducted on 11 pieces of young adult literature and media. Findings note trends in titles to discuss complexities of access to sport within the context of gender, race, and safety in sport. This research can contribute to supporting publishers, authors, and librarians in pursuit of nuanced representations of sport, access, Title IX, and national narrative.

 Description:— Spermogonia amphigenous, surrounded by greenish-yellow lesions, densely grouped, honey-yellow, subepidermal, flask-shaped, type 4 of Cummins & Hiratsuka (2003). Aecia is mostly hypophyllous, cupulate with peridia, Aecidium - type. Peridial cells firmly conjunct, cubic to polygonal, hyaline. Aeciospores catenulate, globose to subglobose, angular, 15.5–18.0 × 13.0–17.5 µm (av. 17.0 × 14.5 µm); walls hyaline, 0.4–0.8 µm (av. 0.6 µm) thick, densely verrucose with big granules.
 Immature uredinia is rarely found. Telia hypophyllous, blackish brown, rounded to broadly elliptic, erumpent. Teliospores broadly clavate, ellipsoid, truncate, rounded or conical at apices, middle or weakly constricted at the septa, rounded or attenuate at the bases, 36.0–53.0 × 15.0–19.5 µm (av. 43.5 × 17.5 µm); walls pale brown, 0.6–1.2 µm (av. 0.8 µm) thick at sides, 6.6–13.5 µm (av. 10.0 µm) at apices; pedicels persistent, hyaline, 14.0–30.0 µm (av. 22.0 µm) long.
 Specimens examined from northeastern CHINA: — Jilin Province, South of Changbai Mountain, spermogonia and aecia on Saussurea sp., 7 July 2017, HMJAU 8891, 8892. Jilin Province, Yanbain City, Erdaobaihe, telia on Carex sp., 29 July 2015, HMJAU 8893.
 Hosts and distribution in northeastern CHINA (Fig. 1): —Spermogonia and aecia on Saussurea sp. (Asteraceae) (D). Telia on Carex sp. (D).
 Note: —Three species, P. ohsawaensis Kakish., P. rupestris Juel and P. vaginatae Juel, have been reported as heteroecious species alternating between Sausurrea and Carex (Juel 1893, Jørstad 1954, Kakishima & Sato 1980, Hiratsuka et al. 1992). Among them, specimens of this clade are morphologically identical with descriptions of P. vaginatae by Juel (1893) and Jørstad (1954). This species is morphologically similar to P. rupestris, but different in the presence of spermogonia and the number of urediniospore germ pores. Teliospore size of P. ohsawaensis is larger than that of P. vaginatae (Kakishima & Sato 1980). Puccinia vaginatae is also morphologically similar and phylogenetically close to P. caricis-atractylodis. However, this species has a distinct phylogenetic lineage (Fig. 3) and its spermogonial and aecial host is different from that of P. caricis-atractylodes. Although Zhuang et al. (1998) reported this species as a doubtful species in China, we confirm its occurrence in China.

description: Environmental Effects Monitoring (EEM) is an important component of metal mining operations which is used to determine if mine discharges are causing adverse effects to the aquatic receiving environment. In 1997, prior to the publication of Environment Canada's draft EEM guidance document, Homestake Canada, Inc. requested that EVS Environment Consultants (EVS) implement an EEM Program for the Eskay Creek Mine. Mining operations at this site result in the production of mine water, waste rock and tailings, which Homestake is authorized to discharge. The Eskay Creek Mine EEM program was designed to assess whether mine discharges cause exceedances of the BC Freshwater Aquatic Life Criteria in the receiving environment and/or adverse effects to resident aquatic biota. The program includes monitoring of water, sediment, periphyton, benthic invertebrate communities, and bioaccumulation studies (no fish are present in the creeks draining the mine site). Results of the EEM studies show that water and sediment chemistry appear to be minimally impacted by mine discharges, with several criteria exceedances due to naturally high metal concentrations from the mineral rich drainage. Elevated sediment metal concentrations are present in Ketchum Creek downstream of mine discharges. However, the benthic invertebrate community increases in both abundance and number of taxa, which suggests that metals are not adversely affecting the community. Overall, discharges from the mine do not appear to be impacting sediment or water quality in the Unuk River as this system contains naturally high metals concentrations due to the mineralized drainage. Following the conclusion of each annual EEM program, results are reviewed to ensure that the objectives of the program are being met. This program is an excellent example of how science and adaptive management can be used to help mines achieve their environmental monitoring goals.

description: The cut and join operations play important roles in tensor models in general. We introduce a generalization of the cut operation associated with the higher order variations and demonstrate how they generate operators in the Aristotelian tensor model. We point out that, by successive choices of appropriate variations, the cut operation generalized this way can generate those operators which do not appear in the ring of the join operation, providing a tool to enumerate the operators by a level by level analysis recursively. We present a set of rules that control the emergence of such operators.

Programme for International Student Assessment
Common Core State Standards (Education)

description: Student achievement in mathematics continues to be compared internationally, with the results indicating that students in other developed countries are outperforming students from the United States. Mathematical modeling is an expectation in both the new Common Core State Standards and the Programme for International Student Assessment (PISA). This study seeks to find the differences in expectations for students in mathematical modeling between the United States and Singapore, which is one country that regularly outperforms the U.S. on international assessments. Since teachers and students regularly use textbooks for curriculum, homework, and other resources, this study compares two textbooks from the U.S. with the high school series adopted in Singapore. More specifically, the aim of this study is to compare frameworks of mathematical modeling and code to-be-solved problems in algebra textbooks using characteristics common to all frameworks. While the U.S. textbooks explicitly state which word problems address the expectation of mathematical modeling, the Singapore program does not have this attribute. So, an equivalent chapter (in objective and number of to-be-solved problems) in all three textbooks will be coded for evidence of the expectations of mathematical modeling.
      The results of this study indicate that no standard framework for mathematical modeling exists, but there are multiple areas of overlap. This study found that the ratio of word problems to numerical problems was comparable in the three textbooks, although the U.S. algebra textbooks used in a one-year course had the same number of to-be-solved problems as the four-year Singapore series. Results also indicate that to-be-solved problems in the Singapore textbook series do not provide students with more explicit mathematical modeling instructions than do the U.S. textbooks. This study also found that the interpretation of to-be-solved problems differed according to the experience of the rater.  None of the textbooks in this study provided to-be-solved problems that asked students to engage in the mathematical modeling cycle as delineated by any of the four frameworks.

As an application, we calculate the energy correlator in the crossover regime between preserved and fully broken time reversal symmetry. We discuss the range of validity of our results and compare them with the predictions of random matrix theories.

description: This study originally aimed to explore the possible relationship between the University of

their library usage. Due to unforeseen constraints this paper has shifted to focus on how
academic libraries can improve civic literacy on campuses. This paper is now exploring
the question: how can academic libraries improve civic literacy in a time of rising
distrust, misinformation, and social media? The extent of this paper will use the grounded
theory to analyze previous research and studies to compile recommendations for
increasing civic literacy in undergraduates. Although this country has seen an increase in
political engagement, there is a lack of literacy and understanding of civics and present-
day politics. This paper aims to further contextualize how academic libraries, such as
UNC, can proceed to celebrate political engagement while emphasizing and educating
civic literacy.

description: The study examines the role of music in the lives and work of 20th century mathematicians within the framework of understanding the contribution of affect to mathematical thinking. The current study focuses on understanding affect and mathematical identity in the contexts of the personal, familial, communal and artistic domains, with a particular focus on musical communities. The study draws on published and archival documents and uses a multiple case study approach in analyzing six mathematicians. The study applies the constant comparative method to identify common themes across cases. The study finds that the ways the subjects are involved in music is personal, familial, communal and social, connecting them to communities of other mathematicians. The results further show that the subjects connect their involvement in music with their mathematical practices through 1) characterizing the mathematician as an artist and mathematics as an art, in particular the art of music; 2) prioritizing aesthetic criteria in their practices of mathematics; and 3) comparing themselves and other mathematicians to musicians. The results show that there is a close connection between subjects’ mathematical and musical identities. I identify eight affective elements that mathematicians display in their work in mathematics, and propose an organization of these affective elements around a view of mathematics as an art, with a particular focus on the art of music. This organization of affective elements related to mathematical thinking around the view of mathematics as an art has implications for the teaching and learning of mathematics.

description: Research on the relationship between mathematics education and society has established that societal change can have a direct effect on mathematics education. Qatar experienced a large amount of societal change since its leadership change in 1995. The literature would suggest that changes in mathematics education in Qatar would follow. The purpose of this study was to investigate the changes in mathematics education in Qatar from 1995 until 2018 and to understand the reasons for these changes. This study applied historic research methods in the form of primary source analysis. The primary sources consisted of text analysis and in-depth interviews. The texts included published reports from the Ministry of Education in Qatar and Qatari mathematics textbooks. Seven in-depth, semi-flexible interviews were conducted with educators involved with Qatar’s mathematics education system within the timeframe of interest. The findings revealed that there were significant changes in mathematics education in Qatar during this timeframe. Specifically, changes were made to the mathematics standards and curriculum, the mathematics language of instruction, mathematics assessments, and mathematics teachers’ preparation. New mathematics standards were created, and government-issued textbooks were abandoned for many years to encourage autonomy and creativity. The language of instruction in the mathematics classroom was transitioned from Arabic to English, and then back to Arabic again. New, national mathematics assessments were created to track the new mathematics reform project. They were later abandoned. The reasons for these many changes, and the challenges they created, touched on many different areas of research in mathematics education and sociology. These included policy borrowing, the language of instruction, knowledge societies, rentier societies, and the relationship between mathematics and society. The findings from this study confirmed that the rapid societal changes that occurred in Qatari society during this timeframe were mirrored by rapid changes in mathematics education within the country.
Stochastic Behavior of Effective Field Theories Across Threshold

description: We explore how the existence of a field with a heavy mass influences the low energy dynamics of a quantum field with a light mass by expounding the stochastic characters of their interactions which take on the form of fluctuations in the number of (heavy field) particles created at the threshold, and dissipation in the dynamics of the light fields, arising from the backreaction of produced heavy particles. We claim that the stochastic nature of effective field theories is intrinsic, in that dissipation and fluctuations are present both above and below the threshold. Stochasticity builds up exponentially quickly as the heavy threshold is approached from below, becoming dominant once the threshold is crossed. But it also exists below the threshold and is in principle detectable, albeit strongly suppressed at low energies. The results derived here can be used to give a quantitative definition of the `effectiveness' of a theory in terms of the relative weight of the deterministic versus the stochastic behavior at different energy scales.

Technological Shifts in Academic Libraries: A Qualitative Inquiry into Librarians’ Perspectives
Creators: name: McKinnell, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Academic libraries have always needed to be responsive to changes in emerging technology over time. As library resources have continued to become ever more digitized, there is a growing need for librarians to gain new technological skills. This qualitative study used semi-structured interviews with instructional librarians in academic libraries to explore what current technological shifts academic librarians are experiencing, how they are adapting to those changes, and what technological skills are most needed in academic libraries today. This study contributes insight into current technological changes in academic libraries like the continued impacts of Covid-19 and AI, factors unaccounted for in the existing literature. The results show that while there is a desire from academic librarians to learn more about AI and skills related to programing and data visualization, the most needed technological skill remain soft skills like curiosity, empathy, and a willingness to learn.
Mathematics Self-Efficacy and Flow in Developmental Mathematics Students

subject: Self-efficacy

description: This study examined mathematics self-efficacy and the characteristics of flow in the context of performing mathematical tasks.  In particular, it explored the subjective experiences of 113 undergraduate students enrolled in a developmental mathematics course while they were independently solving certain mathematical problems.  This study supplemented the literature on the role of self-efficacy as a mediator of the effect of the challenge/skill ratio on flow by applying it to the context of mathematical problem solving. This study also expanded the discussion on how findings may indicate a direction for further research on mathematics anxiety.   Additionally, the relationship between mathematics self-efficacy and flow-like experiences as measured by the Flow Short Scale was considered.

Educational psychology

description: The purpose of this study was to verify Bandura's theory on the relationship of self-efficacy and performance particularly in mathematics among high school students. A rural school in the Philippines was selected for its homogenous student population, effectively reducing the effects of confounding variables such as race, ethnic and cultural backgrounds, socioeconomic status, and language. It was shown that self-efficacy was a positive but minor predictor of future performance only for male students who previously had higher mathematics grades. The effects were different between genders. It was not a strong predictor for women regardless of previous grades, and men with weaker mathematics skills. On the other hand, mathematics self-efficacy was predicted by previous mathematics achievement for women; and also the number of siblings and parental education for the higher performing women. The use of a second language in the mathematics classroom negatively affected confidence and performance. It was also found that there were differences in terms of academic behavior, peers, and family life between students with high and low self-efficacy. Positive behaviors were found for all female students regardless of self-efficacy levels and fewer were found among men. Negative behaviors were only found among low self-efficacy students. No differences were found in terms of the lives and families of the participants, but the interviews revealed that family members and their experiences of poverty affected educational goals and ambitions. In terms of other dispositional factors, students expressed classroom and test anxieties, concerns of being embarrassed in front of their classmates, and beliefs that mathematics was naturally difficult and not enjoyable. The students who did not talk about any of these themes were better performing and had higher self-efficacy scores.

description: This study looks at the use of integrated mathematics and music lessons at the high school level. Four lessons were taught by the researcher in both a research and a control class to determine how mathematically motivated music instruction affects students understanding of operations of functions, composition of functions, inverse functions and domain and range. A pretest-posttest was used to determine the effect of these lessons and a questionnaire was used to identify differences between groups and to help determine the effect of musical applications of mathematics on students’ mathematical perceptions, self-efficacy and grit. The pretest-posttest included both a standard mathematics section and a section involving non-musical applications. A gain score approach using independent sample t tests was used to determine the impact of the integrated instruction. The research group demonstrated significantly greater gains both overall and on the applications portion of the exam. Additional qualitative analysis was done to determine how the posttests differed between groups. Three major differences were identified: the research group used function notation more frequently than the control group, the control group demonstrated confusion between composition of functions and inverse functions while the research group did not and the research group showed more mathematical work for the applications portion of the exam than the control group. Qualitative analysis was also done to identify trends in the questionnaire data. Among the major differences between groups was the increased willingness to work with mathematical applications in the future by the research group compared to the control group. The integrated instruction led to comparable and in some cases significantly better mathematics outcomes than the control group and led students to an increased willingness to work with mathematical applications both on the posttest and moving forward.

Post closure mine dewatering and treatment of contaminated waters at the Sullivan Mine in Kimberley, B.C.
Creators: name: Tarasoff, Dan

Publisher: name: The University of British Columbia
Year: 2009

description: The Sullivan Mine has been operated by Cominco Ltd. since 1909, and is scheduled for closure in December of 2001. The Sullivan ore body is acid generating but operated for many decades before the need to control acid rock drainage (ARD) was recognized. Presently, the generation of ARD can not be prevented, only mitigated. The main sources of ARD include drainage from the underground mine workings, run off and seepage from mining and milling wastes and discharges from the operating tailing ponds. The generation of ARD is expected to continue for an indefinite period after closure. While several projects have been undertaken to minimize the generation of ARD in the last 20 years of mine and concentrator operation, a plan to deal with the on-going generation of these contaminated waters after closure was required. Components of the existing ARD mitigation system will continue to function with some modifications to account for the reduction in ARD volumes generated due to reclamation efforts and the cessation of mining and milling operations. The Drainage Water Treatment Plant (DWTP), which utilizes lime to increase pH and remove metals from ARD into a high-density chemically stable sludge, is the key to current and long-term treatment of contaminated waters. Collection and storage of ARD prior to treatment at the DWTP is another important aspect of ARD control. The DWTP cannot operate continually at design capacity with the expected reductions in post closure ARD flows. For post closure operation, safe storage of contaminated waters is required until the volumes will allow the treatment plant to operate at design levels for a reasonable period of time. A two-reservoir system utilizing the under-ground mine and a surface pond has been designed for contaminated water storage. Three deep-well underground pump stations will be located within the mine. The mine will be allowed to fill to a predetermined level, after which, mine water will be pumped to the above-ground ARD reservoir and subsequently to the DWTP for treatment and discharge to the St Mary River. The DWTP will operate on a campaign basis during periods when the impact on the receiving water, the St Mary River, is minimized.

description: Mathematics education researchers have rarely focused on the effects of popular culture on young people’s perceptions of mathematics.  Such research is needed to determine what messages students may be receiving; and furthermore, how students may be relating to these messages and if there are any differences by age, ability, ethnicity, or gender.  These questions are critically important to the field – its research contributes to the better understanding of how young people are influenced by depictions of mathematics in popular culture.  Research questions were explored relating to popular culture, media, and mathematics investigating whether secondary school students receive messages about mathematics from popular culture, the content of those messages, and how young people relate to those messages.  An instrument was designed and developed to elicit students’ responses to videos about mathematics and other popular culture artifacts.  Of particular interest was determining if perceptions of mathematics in popular culture differ by gender, race, and other demographic factors.
      There appear to be common messages depicted about mathematics in popular culture; for example, “Asian students are good at math,” “math is hard,” “math is irrelevant to the real world,” “boys are smarter than girls at math,” as well as others.  Overall, young people thought popular culture “only shows nerds being good at mathematics” and that “cool kids are not often shown mathematically capable.”  Girls and boys showed differences of the domains “math is hard” and “math is fun.”  Young people from different ethnic groups had varying perceptions of “other subjects are valued more than mathematics” and “it is cool to be smart in math,” but had similar perceptions of “math is not a skill one is born with.”
      There is substantial work in this area in the humanities, but not in mathematics, and it is anticipated that researchers and practitioners alike will welcome the results of this research.
