Typeface: Machine-Viewing Gentrification On Storefront Imagery In Bedford-Stuyvesant, Brooklyn, Alexander Mcquilkin

Dissertations, Theses, and Capstone Projects

Gentrification—broadly, the replacement of a less powerful group by a more powerful one in an urban context—is oft-discussed in the popular press, but its definition is much-debated in the urban planning literature. Furthermore, academic treatments of displacement understandably focus on measurable yet fairly abstract indicators like changes in rent or income, whereas neighborhood change is often registered by residents on the ground using visual, but difficult-to-quantify markers like retail turnover. This project uses image recognition technology on a set of storefront photos to index the visual streetscape of a neighborhood, as well as to track changes to that portrait over …

Courts Of New York: A Visual Atlas Of The City’S Public Basketball Spaces, Nathaniel Rattner

Dissertations, Theses, and Capstone Projects

Basketball courts in New York City are recreation facilities, community anchors and part of the city’s cultural image. In the basketball capital of the world, New Yorkers are rarely more than a few blocks away from a court. The visual diversity of these courts, however, is not widely documented in systematic ways.

This project makes that diversity visible to the public, combining open data, aerial imagery and computational analysis to document this important public space across the five boroughs. It is a narrative story and digital atlas of New York City’s public basketball courts, using surface color as a way …

Mind The Gap: Morphological Defectivity And Suffixal Competition In Polish, Szymon E. Zuberek

Dissertations, Theses, and Capstone Projects

This study investigates morphological defectivity and suffixal competition in the genitive singular of Polish masculine inanimate nouns. Drawing on survey-based grammaticality judgments from native speakers, it examines how respondents select between the suffixes -a and -u or reject both as unacceptable, thereby signaling defectivity. Mixed-effects logistic regressions revealed that defectivity was rare overall but patterned systematically by age, education, and region, with additional baseline variability across lexical items. Suffix choice showed a strong preference for -a, modulated by age, education, and region, with additional baseline variability across lexical items. These findings inform our understanding of paradigm structure, sociolinguistic variation, and …

Sumthin: A Context-Dependent African American Vernacular English Word For Variables, Mark Apedo

Journal of Humanistic Mathematics

If mathematics is a language, then African American Vernacular English (AAVE) could hold the key to a fascinating understanding of the evolution of algebra from human speech in North America. The use of the pronoun something (sumthin) to depict an unknown amount of money that varies implies that algebra developed as a logical necessity in human communication. Exploring this phenomenon and leveraging it to demonstrate the concept of algebra could enhance the comprehension of the subject among speakers of AAVE.

A Note On Modeling Prejudice, Alan Lockard, Edwin Harcourt

Journal of Humanistic Mathematics

We model prejudice in the context of an iterated prisoner’s dilemma tournament. Prejudice here is defined as the inability to distinguish amongst members of an identifiable group. We run a computer simulation where agents of one of two groups with defined strategies are randomly matched against each other. The agents either cooperate with or defect against the agent they are matched with. Our focus is on agents who play an unprejudiced version of the Tit-for-Tat strategy (cooperate with any player in the first encounter, and then apply the same strategy [defect or cooperate] that the opposing player played against them …

Exploring The Dynamics Of Romantic Relationships Through The Lens Of Prem Rog, Umang Jain, Dheeraj Sharma, Pranay Goswami, Kuldeep Malik

Journal of Humanistic Mathematics

Romantic relationships are dynamic events that begin, grow, and frequently remain for a long time in a stagnant or fluctuating state until possibly dissipating. Although they are unquestionably the most significant dynamic events in our lives, dynamic systems theory has only recently included them in its formal framework. Without a mathematical model, it would be impossible to analyze and comprehend the dynamics because, in general, love stories are too brief to allow things to stabilize and are affected by the ups and downs of the surrounding community. In this paper, we set up models made up of four ordinary differential …

The Abcs Of Modified Bond Duration And Wxyzs Of Bond Convexity

Journal of Economics and Finance Education

By breaking the mathematical derivation of Macaulay Duration, Modified Duration, and Bond Convexity into smaller easily calculated component parts, a more manageable means of calculation for these bond measures emerges for the student. Further, an Excel spreadsheet or an algorithm within a programming language can also be implemented using these smaller component calculations. The Excel template provided can be made into an assignment or used as a resource for the student.

An Empirical Implementation Of A Two-Standard-Deviation Investment Signaling Framework Across Multiple Asset Classes

Journal of Economics and Finance Education

This paper presents a pedagogically driven application of a quantitative investment signaling model based on two standard deviation bands. Deviations beyond the two standard deviation range are interpreted as potential mean reversion signals, triggering tactical shifts in asset allocation or trading actions. Students construct the models in Excel using live market data, overlaying asset returns against calculated deviation bands to inform decisions. The firsthand approach emphasizes applied learning and critical thinking, with students analyzing model results and presenting empirical findings. Evidence suggests this experiential method significantly enhances student engagement, comprehension, and retention of investment strategy concepts across diverse financial settings

Coase, Thaler, And Behavioral Economics: Methodological Considerations

Journal of Economics and Finance Education

In their experiments to measure the endowment effect in market settings, Kahneman, Knetsch, and Thaler (1990; hereafter KKT) assessed the assumption of zero transaction costs associated with the Coase theorem. Their study recruited a sample of advanced undergraduate economics students who were placed in a market setting using coffee mugs as real-world goods, under conditions in which there were zero transaction costs. Their results suggested that an endowment effect lowered trading volume, which should not have occurred if Coase theorem worked in practice. We reexamine the research design employed by KKT, as well as their study’s statistical analysis and results.

Analysis Of Coverage Of Tuberculosis Prevention Therapy (Tpt): Literature Review, Septia Rahmalina, Ede Surya Darmawan

Journal of Indonesian Health Policy and Administration

Tuberculosis Preventive Therapy (TPT) is a crucial intervention for tuberculosis (TB) control, particularly among high-risk groups such as household contacts of TB patients and people living with Human Immunodeficiency Virus (HIV). Despite being recommended by the World Health Organization (WHO), TPT implementation still faces challenges at the primary care level. This study employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method to review 11 articles published between 2021 and 2025 that were relevant to TPT implementation in various high-TB burden countries, including Indonesia. The main barriers identified were input (logistics, training), process (tracing, education, monitoring), and output …

A Virtual-Reality-Based Dental Simulator For Endodontics With Automated Formative Feedback, Yousef Salah Abo El Ela

Theses and Dissertations

Advancements in virtual reality (VR) and haptic technology are transforming the landscape of medical and dental education, offering new avenues for safe, immersive, and repeatable training experiences. Within dentistry, endodontics presents unique challenges for preclinical education due to anatomical complexity, limited access to extracted teeth, ethical concerns, and the shortcomings of conventional plastic models. Despite endodontics specific plastic teeth being available, they fall short of replicating the hardness of real extracted teeth, are relatively costly compared to generic plastic teeth, and are ultimately a disposable item which makes them inadequate as a sustainable long-term solution. Extracted teeth do a much …

Modern Science, Enlightenment, And The Domination Of Nature: No Exit?, William Leiss

Fast Capitalism

"The disease of reason is that reason was born from man’s urge to dominate nature." —Max Horkheimer, Eclipse of Reason (1947)

In the fuller passage from which this extract is taken, Horkheimer locates the origins of the ‘collective madness’ of modern times in ‘in primitive objectification, in the first man’s calculating contemplation of the world as prey’ (176). Perhaps all one can say in response is, if this diagnosis is correct, there is certainly no cure, so we might as well get on with our lives.

In the early sections of this paper I will first note briefly the argument …

Economic Impacts Of Abolishing Vertical Integration In The Us Pork Industry, Konstantinos Giannakas

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

This paper develops a multi-market framework of analysis of vertical relationships in pork production and game theoretic models of heterogeneous firms to examine the economic, market and welfare impacts of abolishing vertical integration in the US pork sector. Different scenarios on the causes of vertical integration and the potential states of nature that can emerge after the removal of this vertical market arrangement are considered within this framework. Analytical results are consistent across the different scenarios and forms of strategic interactions between pork producers and indicate that the abolishment of vertical integration in the US pork sector will hurt pork …

Economic Outlook Of Battle Creek: Challenges And Opportunities, Iryna V. Lendel, Chloe Wieber, Sevrin Williams, Gerrit Anderson

Upjohn Institute Technical Reports

This report by the W.E. Upjohn Institute for Employment Research examines labor market dynamics in Battle Creek, finding that roughly 75 percent of jobs in the city are held by workers who live outside the city limits, with significant skill mismatches between city residents and local employer needs. This mismatch helps explain persistently low wages, elevated poverty rates, and high reliance on public assistance among city residents despite a strong manufacturing base and growing logistics, food processing, and machining sectors. Limited housing supply, inadequate public transportation, and childcare shortages further restrict residents’ access to employment. The report underscores the urgency …

Critical Design And The Robotic Imaginary: Design Criticism And Critical Robots, Jörgen Behrendtz

The Journal of Sociotechnical Critique

This paper brings critical design and design criticism to critical robot studies. Critical design can be described as an umbrella term for approaches making use of speculative designs to highlight and challenge narrow assumptions, preconceptions or even taken-for-granted truths about the role products play (in a wide sense) in everyday life. Design criticism refers to a reasoned procedure that investigates emancipatory and/or limiting potentials of designs, theorizes the roles of affordances, materials and embodied perception as epistemological resources in media interaction, and clarifies connections between specific design choices and their associated experiential qualities, seductive powers, ideological underpinnings, material operations, and …

Are Banks "Ripping Off' The Consumer When It Comes To Mortgages?

Journal of Economics and Finance Education

In this pedagogical paper, we answer two questions: If someone has a fixed-rate mortgage and pays it off after only a few years, is the bank "ripping off' the consumer because of the low equity; and when is the interest portion of a mortgage payment exactly equal to the principal portion? The mathematics inherent to a fixed-rate mortgage dictate that a greater portion of interest is paid in the early years. To find the exact point in time when the interest and principal payments are exactly equal requires examining this question using continuous function mathematics.

Know Math Or Take A Bath On A Finance Final Exam

Journal of Economics and Finance Education

Math is central to finance education, yet three-quarters of this sample of 159 introductory finance students lack critical quantitative skills on the first day of class, leading to overall underperformance. By utilizing criterion-referenced mathematics pretest items and matching applied finance posttest items, we find that students with substandard math skills rarely catch-up in the quantitative aspects of introductory finance. Indeed, the pretest determines a significant proportion of final exam performance, with the average student gaining a meager 5% between pretest and posttest. We discuss curricular implications of these findings and research-based approaches to facilitate course readiness.

Does Math Confidence Matter? How Student Perceptions Create Barriers To Success In Economics Classes

Journal of Economics and Finance Education

One of the most common obstacles in the economics classroom is facing students’ disinclination to perform tasks requiring basic quantitative skills. Economics, relative to other disciplines, is particularly bridled by this challenge since mastery of economics requires sufficient mathematical proficiency to elicit anxiety and resistance in many students but is not widely regarded as math intensive enough to generate a selection effect of highly quantitative students. This paper attempts to measure undergraduate economics students’ perceptions of their level of “mathiness” or mathematical abilities and anxieties and then identifies the impact of those perceptions on the students’ performance in economics courses.

Clarifying The Meaning Of Noninteger N Values In Annuity Calculations

Journal of Economics and Finance Education

Time value of money problems are integral to finance. We focus attention on the issues raised when a noninteger solution results from solving for the variable N (number of periods) in a time value of money annuity problem. We show that such a numerical solution, while mathematically correct, can deviate from the narrative of the problem. This deviation from the narrative could cause misunderstandings between instructors and their students and practitioners and their clients. We demonstrate how instructors and practitioners can explain the deviation from the narrative in such cases, and how cash flows can be adjusted to avoid missing …

An Excel-Based Approach For Teaching Markowitz’S Portfolio Optimization Theory

Journal of Economics and Finance Education

This paper presents a simple method for teaching the Markowitz Portfolio Optimization topic. The use of Microsoft Excel or Corel Quattro Pro enables students and investors who do not possess a great deal of mathematical and programming expertise to identify meanvariance efficient portfolios which consist of more than two assets. Through this hands-on learning experience, students achieve a deeper understanding of the theory. The exercise also gives the students an eye opening lesson on the practical usability of spreadsheets.

Predictors Of Success In An Online Undergraduate Core Course In Finance

Journal of Economics and Finance Education

Because finance is a technically oriented business subject where competence in math and accounting plays a role in student success, we posit that technical knowledge, as proxied by math and accounting pre-tests, may predict success in an online undergraduate finance course. Since little or no lecture support is generally offered while taking an online course, students that struggle with math or accounting may have a greater challenge with the online format for a finance course. Accordingly, the purpose of this study is to evaluate the key determinants of success in an online core course in finance.

Teaching Mathematical Economics Using Public Choice: The Median Voter Model

Journal of Economics and Finance Education

The median voter model (MVM) is a core model in public choice comparable to the demand and supply competitive market model in microeconomics. In this paper I introduce and discuss the mathematical treatment of a simple version of the model. This allows instructors to apply a wide range of concepts commonly introduced in a first undergraduate class in mathematical economics. The approach will help students to understand the interplay of concepts separately introduced during the first phase of the course. Hopefully the method will foster an interest in public choice through the study of one of its most important benchmark …

Modelling Land Use Land Cover Change In Banyumas Regency Using Remote Sensing Data For Tourism Policy Evaluation, Revi Hernina, Arif Wicaksono, Adi Wibowo, Astrid Damayanti

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Tourism is essentially a geographical phenomenon, encompassing the movement and flow of people and spatial distribution patterns relating to land use consumption. The impacts of tourism on LUCC must track and monitor regrading effected to environment and human side. For decades, Banyumas Regency has been known for its famous tourist destinations such Baturaden District and numerous waterfalls. However, the development of tourism infrastructures within its vicinity has sparked complaints from communities, particularly damaged roads and decreasing tourist visits. From environmental perspective, excessive tourism development might cause decreasing natural carrying capacity. Therefore, to provide deeper analysis regarding the current tourism development, …

Yield-To-Maturity And The Reinvestment Of Coupon Payments: Reply

Journal of Economics and Finance Education

Our original note addressed a common misconception that to earn the yield-to-maturity (YTM) on a coupon bond an investor must reinvest the coupon payments. Shirvani and Wilbratte (2009) take issue with our presentation and results. We will demonstrate that their arguments entirety rest on the proposition that the YTM must equal the realized compounded yield (RCY). This is a construct that explicitly assumes coupon reinvestment. We made no claim in our original presentation with regard to their proposition, because it is not required to calculate the YTM. Furthermore, we will discuss their claims with regard to the “economic significance” of …

Yield To Maturity Is Always Received As Promised: A Reply

Journal of Economics and Finance Education

This note attempts to further spell out why it is a myth that YTM is viewed as only a promised but not really earned interest rate. It addresses some misconceptions in Shirnani and Wilbratte (2009, this issue) on what, between YTM and RCY, is a true rate of return of a coupon bond, why YTM is NOT just a “fictitious mathematical construct”, and why YTM has nothing to do with yield curve.

The Relationship Between The Promised And Realized Yields To Maturity Revisited

Journal of Economics and Finance Education

This paper reaffirms the long-held view that the promised yield to maturity of a coupon bond can be realized only under certain restrictive conditions. Specifically, the realized yield equals the promised yield only if the spot rate and yield curves are flat and remain unchanged throughout the term of the bond, a condition which rarely if ever holds. In addition, we explain that, regardless of the reinvestment rates, the promised yield on a coupon bond will be realized, provided that the bond is held not to its maturity but to its duration.
