Recurring Errors In Studies Of Gender Differences In Variability, Theodore P. Hill

Research Scholars in Residence

The past quarter century has seen a resurgence of research on the controversial topic of gender differences in variability, in part because of its potential implications for the issue of under- and over-representation of various subpopulations of our society, with respect to different traits. Unfortunately, several basic statistical, inferential, and logical errors are being propagated in studies on this highly publicized topic. These errors include conflicting interpretations of the numerical significance of actual variance ratio values; a mistaken claim about variance ratios in mixtures of distributions; incorrect inferences from variance ratio values regarding the relative roles of sociocultural and biological …

Patchy Forsterite Clouds In The Atmospheres Of Two Highly Variable Exoplanet Analogs, Johanna M. Vos, Ben Burningham, Jacqueline K. Faherty, Sherelyn Alejandro, Eileen Gonzales, Emily Calamari, Daniella Bardalez Gagliuffi, Channon Visscher, Xianyu Tan, Caroline V. Morley, Mark Marley, Marina E. Gemma, Niall Whiteford, Josefine Gaarn, Grace Park

Faculty Work Comprehensive List

We present an atmospheric retrieval analysis of a pair of highly variable, ∼200 Myr old, early T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J21392676+0220226 using the Brewster retrieval framework. Our analysis, which makes use of archival 1–15 μm spectra, finds almost identical atmospheres for both objects. For both targets, we find that the data is best described by a patchy, high-altitude forsterite (Mg2SiO4) cloud above a deeper, optically thick iron (Fe) cloud. Our model constrains the cloud properties well, including the cloud locations and cloud particle sizes. We find that the patchy forsterite slab cloud inferred from our …

Principal Perceptions Of The Impact Of Turnaround Practices On Student Achievement In New York City Charter Schools, Christina D. Brown

Seton Hall University Dissertations and Theses (ETDs)

Principal leadership is at the core of successful school turnaround. This qualitative study explored principals’ perceptions of the success or failure of turnaround methods in their New York City charter school communities. Principal leadership of low-performing schools is one of the most important elements of turnaround success (Stronge & Xu, 2021). While much research has been conducted to determine what makes a principal effective or ineffective, not much research exists that reveals the perspective of turnaround principals regarding the importance of their roles in dramatically increasing student achievement. The theoretical framework for this study was guided by the work of …

A Mathematical Investigation Of Landauer’S Principle, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

A minimal mathematical approach is used to state Landauer’s principle in a precise, general way. The results are obtained by means of a rigorous development which is based on the use of quantum statistical mechanics. A mathematical form of the principle results as an equality rather than an inequality. The equality version does imply the original statement of the principle as introduced by Landauer.

Thin Film Deposition Of Mop, A Topological Semimetal, Robert Browning, Paul Plachinda, Raj Solanki

Physics Faculty Publications and Presentations

MoP is a topological semimetal which has drawn attention due to its unique electrical and optical properties resulting from massless electrons. In order to utilize these properties for practical applications, it is necessary to develop a technique to produce high-quality, large-scale thin films of this 2D material. We report below our initial results of growth of MoP thin films using atomic layer deposition (ALD), where the film grows layer-by-layer. These films were grown on 5 cm × 5 cm silicon oxide coated Si wafers. Resistivity versus temperature measurements show that these films are metallic and includes a partial superconducting phase. …

Regulatory Managerialism Inaction: A Case Study Of Bank Regulation And Climate Change, Hilary J. Allen

Scholarly Articles in Law Reviews & Journals

In November of 2029, Hurricane Penelope struck New York City as a category two storm. Work had started on a wall to protect Manhattan from rising sea levels and storm surges, but the work was incomplete, and significant damage to Manhattan real estate was sustained. While almost all that real estate was insured, insurance companies were compromised by the sheer magnitude of the losses. Even with significant federal subsidies, they were unable to meet their full commitments on insurance policies. Some commercial real estate firms, who had never really recovered from the shift to remote working during the Covid pandemic, …

Applying Positional Encoding To Enhance Vision-Language Transformers, Xuehao Liu, Sarah Jane Delany, Susan Mckeever

Conference papers

Positional encoding is used in both natural language and computer vision transformers. It provides information on sequence order and relative position of input tokens (such as of words in a sentence) for higher performance. Unlike the pure language and vision transformers, vision-language transformers do not currently exploit positional encoding schemes to enrich input information. We show that capturing location information of visual features can help vision-language transformers improve their performance. We take Oscar, one of the state-of-the-art (SOTA) vision-language transformers as an example transformer for implanting positional encoding. We use image captioning as a downstream task to test performance. We …

Comparison Of Pulsed Electroacoustic Measurements And Af-Numit3 Modeling Of Polymers Irradiated With Monoenergetic Electrons, Zachary Gibson, J. R. Dennison, Brian Beecken, Ryan Hoffmann

Journal Articles

Successful spacecraft design and charging mitigation techniques require precise and accurate knowledge of charge deposition profiles. This paper compares models of charge deposition and transport using a venerable deep dielectric charging code, AF-NUMIT3, with direct measurements of charge profiles via pulsed electroacoustic (PEA) measurements. Eight different simulations were performed for comparison to PEA experiments of samples irradiated by 50 or 80 keV monoenergetic electrons in vacuum and at room temperature. Two materials, polyether-ether ketone (PEEK) and polytetrafluoroethylene (PTFE), were chosen for their very low conductivities so that minimal charge migration would occur between irradiation and PEA measurements. PEEK was found …

Faculty, Staff and Students Publications

The coronavirus disease 2019 (COVID-19) pandemic and associated increase in family care responsibilities resulted in unsustainable personal and professional workloads for infectious diseases (ID) faculty on the front lines. This was especially true for early-stage faculty (ESF), many of whom had caregiving responsibilities. In addition, female faculty, underrepresented in medicine and science faculty and particularly ESF, experienced marked declines in research productivity, which significantly impacts career trajectories. When combined with staffing shortages due to an aging workforce and suboptimal recruitment and retention in ID, these work-life imbalances have brought the field to an inflection point. We propose actionable recommendations and …

Electrical Stimulation While Resistance Training Leads To Greater Gains In Muscle Mass And Strength, Gabriel Narvaez, Jehu Apaflo, Amy Wagler, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

Resistance training (RT) has long been shown to increase muscle strength and muscle mass and is widely recommended for people of all ages and ability levels. Neuromuscular electrical stimulation (NMES) is an involuntary mode of inducing muscle contractions that has been used to prevent muscle immobility, weakness, strength loss, and muscle loss in rehabilitative settings. However, the additive effects of NMES and RT are not well established. PURPOSE:. To determine if superimposing neuromuscular electrical stimulation during a resistance training intervention elicits greater gains in muscle strength and/or muscle mass than resistance training being performed alone. METHODS: An electronic …

Effect Of Acute Exercise Mode On Test Anxiety: Aerobic Vs. Resistance, Natalie N. Trevino, Amber M. Shipherd, Christopher M. Hearon

International Journal of Exercise Science: Conference Proceedings

Test anxiety is a specific type of state anxiety when a person experiences perceived pressure to excel on a test. Test anxiety not only hinders test performance, but the person's long term psychophysiological health. Many students struggle with test anxiety, but females have a higher incidence of test anxiety than males. Bouts of aerobic exercise have been shown to decrease state anxiety, but no work has been done examining the effects of resistant training on state anxiety. PURPOSE: the purpose of this study was to compare the effects of acute aerobic and resistance exercise bouts on test anxiety among …

Effect Of Residual Sugar In High Sugar Grass Silages On Aerobic Stability, G. Pahlow, R. J. Merry, P. O'Kiely, T. M. Pauly, J. M. Greef

IGC Proceedings (1977-2023)

New varieties of Lolium perenne, bred for high sugar content, can contain up to 30% of water soluble carbohydrates (WSC). Only a fraction of such high contents are metabolised during a normal fermentation and the high residual sugar content (RSC) of these silages can improve the efficiency of use of nitrogen by ruminants. However, these RSC at opening for feed-out could be preferentially metabolised relative to fermentation products by all aerobically growing fungi and bacteria present on the forage. A high RSC thus can increase the risk of aerobic deterioration over that of extensively fermented silages, containing predominantly organic …

Recent Developments In Methods To Characterise The Chemical And Biological Parameters Of Grass Silage, R. S. Park, R. E. Agnew, M. G. Porter

IGC Proceedings (1977-2023)

Key points

1. Chemical analysis of forages is expensive, time consuming, environmentally unfriendly and relates poorly to the feed value for production purposes.
2. In vivo characterisation of animal feed is not a feasible option in terms of cost and analysis time.
3. NIRS is a rapid, non destructive, environmentally friendly, multi-analytical technique which can estimate the nutritive value of the feed.
4. NIRS predictive equations developed on a master instrument can be transferred to local and international sites.
5. Future assessment of forages necessitates rapid, stable, instrumentation for ‘in field’ studies.
