Sources And Types Of Social Supports And Their Association With Mental Health Symptoms And Life Satisfaction Among Young Adults With A History Of Out-Of-Home Care, Rhiannon Evans, Colleen C. Katz, Anthony Fulginiti, Heather Taussig

Publications and Research

Young adults with a history of out-of-home care report poorer mental health and life satisfaction compared to non-care-experienced peers. Social support is a known protective factor for mental health. There is limited evidence, however, on the relationship between sources (e.g., family members) and types (e.g., information) of social support and mental health symptoms and life satisfaction in this population. Reporting cross-sectional survey data from 215 young adults aged 18–22 years with a history of out-of-home care, the current study conducted descriptive, bivariate, and linear regression analysis to examine the different sources and types of support young adults receive and their …

Publications and Research

Contributing to the literature on the institutional experiences of undocumented youth, this essay by Holly E. Reed, Sofya Aptekar, and Amy Hsin explores undocumented and “DACAmented” students’ experiences managing their illegality on campus and how college staff and faculty manage that illegality while organizing programs and support. Their analysis of in-depth qualitative interviews conducted with more than a hundred undocumented college students and former students and thirty-five faculty and staff members at the City University of New York identifies multiple points of tension. The “undocumented mismatch” between campus management of illegality and student experiences was evident in the exclusion and …

Adapting Human-Based Transcutaneous Spinal Cord Stimulation To Develop A Clinically Relevant Animal Model, Dillon C. Malloy, Maria Knikou, Marie-Pascale Côté

Publications and Research

Transcutaneous spinal cord stimulation (tSCS) as a neuromodulatory strategy has received great attention as a method to promote functional recovery after spinal cord injury (SCI). However, due to the noninvasive nature of tSCS, investigations have primarily focused on human applications. This leaves a critical need for the development of a suitable animal model to further our understanding of this therapeutic intervention in terms of functional and neuroanatomical plasticity and to optimize stimulation protocols. The objective of this study is to establish a new animal model of thoracolumbar tSCS that (1) can accurately recapitulate studies in healthy humans and (2) can …

"Courts And State-Building: The Welsh Marcher Lordships And The Somali Union Of Islamic Courts," Polity 54(2): 197--25., Zachary C. Shirkey

Publications and Research

This article examines the roles of courts in state-building and aims to bring the state-building literature into deeper conversation with institutional approaches to the study of courts. Doing so highlights that courts can play important roles in state-building including extracting revenue, coercing subjects, and generating legitimacy for the state by justly adjudicating disputes. Of these, courts’ extractive role has been especially understudied. Yet, courts can raise significant sums through fees, fines, and confiscating property, particularly in less-developed states. These three roles of courts in state-building are explored in two highly disparate cases: the medieval Welsh Marcher lordships and the Union …

Parent Perspectives On Early Childhood Education Integration, Maria S. Mavrides Calderon, Gregory Brender

Publications and Research

Former Mayor De Blasio made the expansion of 3-K for All and Pre-K for All a top priority of his administration. In its re-procurement of contracts for community-based early childhood education providers, the De Blasio administration’s Department of Education made it a priority for programs to “foster socio-economic integration at the classroom level.” Mayor Eric L. Adams has spoken of his own experience being educated in segregated schools and has called for students to be exposed to more diverse environments (Shapiro, 2021). It is up to his administration to implement the changes that will foster desegregation in New York City’s …

A-Z Database List Review: Getting Started And Keeping The Momentum, Sonali Sugrim

Publications and Research

Libraries have multiple portals to access their electronic resources. At Queens College, the two access portals are the catalog, Ex-Libris’ Primo, and Springshare’s A-Z Database List. The most recent comprehensive review of the A-Z Database List was conducted five years ago by the previous electronic resources librarian. As such, the list had multiple formats for displaying information and lacked consistency. The supporting information for the overall layout of the list was not helpful to users nor library staff. Users should be able to search for the resources they want without getting bogged down by unnecessary jargon, inconsistencies, and fluff.

Cosmogenic Ages Indicate No Mis 2 Refugia In The Alexander Archipelago, Alaska, Caleb K. Walcott, Jason P. Briner, James F. Baichtal, Alia J. Lesnek, Joseph M. Licciardi

Publications and Research

The late-Pleistocene history of the coastal Cordilleran Ice Sheet remains relatively unstudied compared to chronologies of the Laurentide Ice Sheet. Yet accurate reconstructions of Cordilleran Ice Sheet extent and the timing of ice retreat along the Pacific Coast are essential for paleoclimate modeling, assessing meltwater contribution to the North Pacific, and determining the availability of ice-free land along the coastal Cordilleran Ice Sheet margin for human migration from Beringia into the rest of the Americas. To improve the chronology of Cordilleran Ice Sheet history in the Alexander Archipelago, Alaska, we applied 10Be and 36Cl dating to boulders and glacially sculpted …

Home Sweet Home? Examining Residential Instability And Preschoolers’ Early Mathematics Development, Marisha Kashyap

Publications and Research

In 2020, approximately 13% of all children under five experienced residential instability. Residential instability, also known as housing instability, is known to compromise the socio-emotional and behavioral development of young children. However, there is limited evidence documenting the effect of housing instability on preschoolers' cognitive and academic abilities, in particular the development of mathematics skills. The present literature review argues that unstable residential conditions have important implications for preschoolers’ early mathematics development. First, the current literature review explores the implications of residential instability for the early childhood developmental period. Then this review examines current studies on promotive and risk factors …

The Contemporary American Juvenile Justice System: Revisiting Parens Patriae, Katarzyna Celinska, Amina Cheboubi

Publications and Research

The American juvenile justice system has undergone significant transformations since its inception in the late 19th century. In this paper, the authors seek to analyze the historical context of and subsequent reforms to the juvenile system and process in order to determine whether they remain true to their origins of the legal doctrine of parens patriae. Specifically, the authors contrast rehabilitative notions of parens patriae with the “tough on crime” perspective that developed in the 1990s in response to rising crime rates. This debate is illustrated by landmark Supreme Court cases, waivers to the adult system, increases in the use …

“The Amount Of Labor We Do For Free” And Other Contradictions: A Collective Inquiry Into The Pedagogical Choices Of Cuny Adjunct And Graduate Student Instructors Who Taught With Free Of Charge Materials During The Year 2020, Sami Disu, Joanna Dressel, Jamila Hammami, Marianne Madoré, Conor Tomás Reed

Publications and Research

A collective of five CUNY researchers developed and conducted a survey-based study of how CUNY adjunct and graduate student faculty taught with free of charge materials during the year 2020. A total of 152 respondents filled out the survey. Four themes emerged from the analysis of their responses:

Adapting A Conceptual Framework To Engage Diverse Stakeholders In Genomic/Precision Medicine Research, Karriem S. Watson, Elizabeth G. Cohn, Alecia Fair, Usha Menon, Laura A. Szalacha, Selena M. Carpenter, Consuelo H. Wilkins

Publications and Research

Introduction: Genomic/precision medicine offers a remarkable opportunity to improve health and address health disparities. Genomic medicine is the study of genes and their interaction with health. Precision medicine is an approach to disease prevention and treatment that considers individual variability in genes, environ- ment and lifestyle. Conclusions from studies lacking diversity may hinder general- izability as genomic variation occurs within and between populations. Historical factors, such as medical mistrust, ethical issues related to decision making, and data sharing pose complex challenges that may further widen inequities in genomic/ precision medicine if not appropriately addressed. Although few biomedical studies integrate priorities …

“I Can Math, Too!”: Reducing Math Anxiety In Stem-Related Courses Using A Combined Mindfulness And Growth Mindset Approach (Magma) In The Classroom, Tashana S. Samuel, Sebastien Buttet, Jared Warner

Publications and Research

Math anxiety has become an alarming social justice concern, as it results in negative academic consequences, contributes to disinterest and lack of persistence in STEM programs for underrepresented students, and limits their opportunities in STEM careers. According to research, this fear of math occurs long before students begin working on math problems. When high-math anxious students encounter math situations, anticipation anxiety consumes working memory capacity, inhibits learning, and causes them to severely underperform on mathematical tasks. However, very few studies have been conducted to embed psychological interventions in the classroom in an effort to mitigate both anticipation and execution anxiety. …

We found significant positive correlations between viral loads in wastewater and new COVID-19 cases. The strength of the …

Divergent Water Requirements Partition Exposure Risk To Parasites In Wild Equids, Kaia J. Tombak, Laurel A. Easterling, Lindsay Martinez, Monica S. Seng, Liana F. Wait, Daniel I. Rubenstein

Publications and Research

For grazing herbivores, dung density in feeding areas is an important determinant of exposure risk to fecal- orally transmitted parasites. When host species share the same parasite species, a nonrandom distribution of their cumulative dung density and/or nonrandom ranging and feeding behavior may skew exposure risk and the relative selection pressure parasites impose on each host. The arid-adapted Grevy's zebra ( Equus grevyi ) can range more widely than the water-dependent plains zebra ( Equus quagga ), with which it shares the same species of gastrointestinal nematodes. We studied how the spatial distribution of zebra dung relates to ranging and …

Deepreal: A Deep Learning Powered Multi-Scalemodeling Framework For Predicting Out-Of-Distributionligand-Induced Gpcr Activity, Tian Cai, Kyra Alyssa Abbu, Yang Liu, Lei Xie

Publications and Research

Motivation Drug discovery has witnessed intensive exploration of predictive modeling of drug–target physical interactions over two decades. However, a critical knowledge gap needs to be filled for correlating drug–target interactions with clinical outcomes: predicting genome-wide receptor activities or function selectivity, especially agonist versus antagonist, induced by novel chemicals. Two major obstacles compound the difficulty on this task: known data of receptor activity is far too scarce to train a robust model in light of genome-scale applications, and real-world applications need to deploy a model on data from various shifted distributions.

Results To address these challenges, we have developed an end-to-end …

Spin-Orbit Gravitational Locking - An Effective Potential Approach, Christopher Clouse, Andrea Ferroglia, Miguel C. N. Fiolhais

Publications and Research

The objective of this paper is to study the tidally locked 3:2 spin–orbit resonance of Mercury around the Sun. In order to achieve this goal, the effective potential energy that determines the spinning motion of an ellipsoidal planet around its axis is considered. By studying the rotational potential energy of an ellipsoidal planet orbiting a spherical star on an elliptic orbit with fixed eccentricity and semi-major axis, it is shown that the system presents an infinite number of metastable equilibrium configurations. These states correspond to local minima of the rotational potential energy averaged over an orbit, where the ratio between …
