A Definition Of A Heywood Case In Item Response Theory Based On Fisher Information, Jay Verkuilen, Peter J. Johnson

Publications and Research

Heywood cases and other improper solutions occur frequently in latent variable models, e.g., factor analysis, item response theory, latent class analysis, multilevel models, or structural equation models, all of which are models with response variables taken from an exponential family. They have important consequences for scoring with the latent variable model and are indicative of issues in a model, such as poor identification or model misspecification. In the context of the 2PL and 3PL models in IRT, they are more frequently known as Guttman items and are identified by having a discrimination parameter that is deemed excessively large. Other IRT …

Publications and Research

Background: Mind-body treatments have the potential to manage pain, yet their effectiveness when delivered online for the treatment of low back pain (LBP) is unknown. We sought to evaluate whether a virtually delivered mind-body program integrating tai chi, qigong, and meditation (VDTQM) is effective for treating LBP.

Methods: This randomized controlled trial compared VDTQM (n=175) to waitlist control (n=175). Eligible participants were at least 18 years old, had LBP for at least 6 weeks, were not pregnant, had not previously taken tai chi classes, and had not undergone spine surgery within 6 months. The treatment group received a 12-week VDTQM …

Effective Size Of A Parity-Time-Symmetric Dimer, Li Ge

Publications and Research

Parity-time (PT)-symmetric dimers were introduced to highlight the unusual properties of non-Hermitian systems that are invariant after a combined parity and time reversal operation. They are also the building blocks of a variety of symmetry and topologically protected structures, especially on integrated photonic platforms. As the name suggests, it consists of two coupled oscillators, which can be optical, mechanical, electronic, and so on in nature. In this article, we show that its effective size, defined by the number of lattice sites inversely proportional to the lattice momentum, is surprisingly three instead of two from the perspective of energy quantization. More …

Information Behavior And Hiv/Aids/Sti Awareness Among Bangladeshi Female Sex Workers: Do Informational Programs Help?, Nafiz Z. Shuva, Radia Taisir, Parvez Sazzad Mallick

Publications and Research

Using de Certeau's concepts of “tactics” and “strategies,” this study explores the everyday information seeking behavior of female sex workers (FSWs) in Bangladesh. This study also examined the effectiveness of informational programs on HIV/AIDS and STI in empowering FSWs to negotiate condom use during sex. A mixed method research design was employed in this study, which included face-to-face surveys with 116 female sex workers (FSWs) and four focus group discussions (FGDs) with 23 street based FSWs. The study finds that Bangladeshi female sex workers use “tactics” in meeting their information needs. They reported rarely using formal information sources such as …

Romancing The University: Bipoc Scholars In Romance Novels In The 1980s And Now, Jayashree Kamble

Publications and Research

English-language mass-market romance novels written by BIPOC (Black, Indigenous, and People of Color) writers and starring BIPOC protagonists are a small but important group. This article is a comparative analysis of how recent representations of diversity in this sub-set of the genre, specifically the character of the Black academic and the language of racial justice, compare with the first group of BIPOC novels that were published in 1984 (Sandra Kitt’s Adam and Eva and All Good Things as well as Barbara Stephens’s A Toast to Love). In Adrianna Herrera’s American Love Story (2019), Katrina Jackson’s Office Hours (2020), and …

Green Is The New Black: Exploring How A Philosophical Approach To The Fashion Industry Will Reduce Its Environmental Impact, Darion A. Gibbs

Student Theses and Dissertations

The fashion industry is the third largest contributor to pollution globally, behind only oil and agriculture. It also accounts for one-fifth of the plastic produced annually. Despite its impact, it is hard to trace accountability. For example, mega-retailers often outsource production to developing countries, without strong structures of accountability for their environmental impact. In addition, companies often claim to be environmentally sustainable, but it is easy to inflate the truth, and entities designed to protect consumers have limited enforcement. In this context, who should be held responsible for the fashion industry’s contribution to climate change?

In response, this thesis delves …

Maui Wildfires: A Case Study In Local Government Crisis Communication Response, Joshua A. Voda

Student Theses and Dissertations

When wildfires swept through the island of Maui in Hawai‘i in August 2023, the communities of Olinda, Kula and especially Lahaina were devastated. Thousands of people were displaced, and nearly 100 people were lost. Just like the speed at which the fiery winds consumed these towns, accusations of emergency mismanagement and a host of misinformation spread by word of mouth and online. The primary local government authority for these communities is the County of Maui, currently led by Mayor Richard Bissen. This case study examines the first month of communication from the County of Maui to the affected communities via …

Connecting With A Lost Heritage: The Indigenous Taino Community Of The Caribbean In New York City, Angeles R. Rodriguez Negron

Capstones

Among New York City's diasporic communities lie the Indigenous Tainos, an aboriginal people originally from the Caribbean region. But many people are unaware of their existence. There is a belief among Puerto Ricans and other Caribbean societies that the Tainos are an extinct tribe since the 16th century due to European colonization. The Taino revivalist movement has taken strength during the last 30 years, and more Taino descendants are taking pride on their identity and culture. After 5 months of collaboration with this Indigenous community, Puerto Rican journalist Ángeles Rodríguez Negrón created Miyari Taino, a podcast designed to provide visibility …

The Pima County Jail In A “State Of Full-Blown Crisis”: Inmate Deaths Four Times The National Average, Natalie Robbins

Capstones

Last year, 12 inmates died in custody at the Pima County Jail in Tucson, Arizona. With a 10-year average jail population of 1,827, that is a per capita rate of 656.8 deaths per 100,000 inmates.

According to the most recent data from the Bureau of Justice Statistics, the 2019 national local jail mortality rate was 167 deaths for every 100,000 inmates, making the Pima County Jail’s 2022 per capita death rate nearly four times as high as the national average in 2019.

In a December 2022 memo to the Pima County Board of Supervisors, Pima County Sheriff Chris Nanos wrote …

“Unsanitary, Rundown, Everything Is Broken”: The Reality Of Queer Homeless Shelters, Sunjum Nagpaul

Capstones

Despite the larger need for queer-designated shelters, there are only a handful of them out of hundreds of city shelters. Most of them are for youth except Marsha’s House, located in Belmont in the Bronx, which has an age limit of 30. It also comes with a slew of concerns, like staff who are unfamiliar with LGBTQ+ issues and a layout that can exclude those with physical disabilities. What’s more, queer residents face many of the same challenges others homeless do: dirty and unsanitary facilities that never seem to improve.

The Information Literacy Class As Theatrical Performance: A Qualitative Study Of Academic Librarians’ Understanding Of Their Teacher Identity, Mark Aaron Polger

Publications and Research

This qualitative study examines how academic librarians understand, conceptualize, and describe their teacher identity. The role of the academic librarian has greatly changed due to the advent of information technology. Traditionally, they were generalists, who were responsible for selecting and maintaining library collections. Academic librarian roles have evolved into web developers, information literacy (IL) instructors, emerging technology innovators, marketing and outreach coordinators, open education resources (OER) advocates, and scholarly communication experts. This research investigates the academic librarian as teacher phenomenon, how they describe their professional identity as teachers, the skills, knowledge, and competencies they teach, and their beliefs of how …

Education And The Epistemological Crisis In The Age Of Chatgpt, Casandra Silva Sibilin

Publications and Research

The emergence of ChatGPT and its ability to imitate student work has precipitated a crisis in education. Responses range from practical efforts to detect or prevent ChatGPT use to existential reflection about learning and assessment. However, the crisis is also epistemological, with educators struggling to determine what students know and fearing that student knowledge is diminishing. The educational philosophies of Socrates, Dewey, and Freire suggest that recognition of ignorance of different kinds (inquisitive, predictive, and practical)on the part of educators is uncomfortable but essential for improving the aims and methods of education. In this way, ChatGPT and the philosophy of …

Linguistic Impact On The Use Of The Reliable Digit Span For Performance Validity In A Sample Of English-Spanish Bilingual Adults, Amy Polinsky

Student Theses

Performance validity tests (PVTs) are used alongside neuropsychological assessments to help detect suspect effort. One of the most widely used PVTs, the Reliable Digit Span (RDS), and its latest version, the RDS-revised (RDS-R), have been widely accepted as valid and reliable within the general population. However, as the United States becomes increasingly globalized, questions arise regarding the validity of language-based tests such as the RDS and RDS-R amongst English-Spanish bilingual populations. This study used a within-subject design with 28 bilingual undergraduate students, testing them on the Digit Span (the test that RDS results are based on) in both English and …

Hispanic Empowerment In New York's Municipal Workforces, 2021, Carlos Vargas-Ramos

CUNY Centro, The Center for Puerto Rican Studies

One of the markers of political empowerment of historically marginalized groups in society is not simply the election and appointment of representatives from those groups to governmental institutions; their participation as employees and contractors in the governmental apparatus that provides services and goods to residents of towns, cities and counties also reflects the levels at which members of the community are included and represented. New York City has the largest municipal workforce in the country. New York is also one of the most socially diverse communities in the United States. Yet, as varied as New York City’s municipal workforce is, …

Towards Critical Reflexivity In Gifted Education Teacher Preparation, Inna Kruvi

Theses and Dissertations

Ever since the emergence of gifted education in the United States in the beginning of the twentieth century, the concept of giftedness has been used to marginalize, segregate, and exclude students of particular backgrounds from specialized academic programs. Among the factors that contribute to unequal access to gifted education for ethnically, culturally, linguistically, and economically diverse (ECLED) students, teacher bias, deficit thinking, and insufficient teacher preparation have been identified as especially significant (Coleman et al., 2015; DeWet & Gubbins, 2011; Mansfield, 2015). Among various approaches to mitigate underrepresentation of ECLED students, the concept of cultural humility (Tervalon and Murray-Garcia, 1998) …

What does one do in philosophy? Philosophers look for questions on issues, even where you may not have thought that questions could meaningfully be asked. We look for evidence for what are the most plausible answers even for questions that you may not have believed have answers at all. We all do philosophy sometimes, even if you may not have called it that.

Nigel Warburton describes philosophy as “any human enterprise that involves critical thought about basic questions, like how we should live, what is the nature of reality and so on.” This course will introduce a few of those …
