Energy & Carbon Neutral Nyc, Evan Banks, Elena Zimareva, Elena Malysheva

Publications and Research

In 2016, the world's leading countries signed the Paris Agreement which focused on reducing anthropogenic climate change on the planet. On May 2019, New York State and New York City declared its own ambitious goals aimed at decarbonizing the city and restricting the state’s energy use to relying completely on renewables.

Some of these goals specifically target infrastructure in the city since estimates cite buildings as accounting for nearly 70% of New York’s energy use. The main law of New York’s Climate Policy, Local Law 97, requires all buildings over 25,000 sq ft to reduce their CO2 footprint by 40% …

Green Roof System Integrated Soil Methods, Jude R. Vallon, Ivan L. Guzman

Publications and Research

Large metropolitan areas like NYC are seeking to integrate sustainability into retrofitting buildings for the development of green infrastructure. Among the many environmental issues of urbanization, the UHI (urban heat island) effect and storm water runoff are of particular interest when it comes building structures. Individual buildings can contribute towards mitigating these effects with implementation of vegetative rooftops, i.e. Green Roofs. Commercial buildings are currently receiving government incentives and new constructions are required to include green roof installations. However, if existing buildings are considering the addition of a green roof on an existing roof, they have to factor in the …

Income Disparities Between Levels Of Management Within The Workplace In The Us, Cerlyn K. Ellis

Publications and Research

The continuous rise of inequality particularly in the growing concentration of income at the top level of distribution in the United States has become a great focus of assessment for economists and policy makers. Skilled workers struggle to improve their income compensation by integrating higher level of schooling with on-the-job experience to boost their opportunity and gain the edge in this competitive labor market. Understanding the factors behind this phenomenon is essential to determine whether policy action is needed to reduce income inequality while taking into account other policy objectives. Since the problem won’t be solved without understanding the origin …

An Overview Of The Health Delivery System In The State Of Mississippi, Cerlyn K. Ellis

Publications and Research

Imagine residing in a high-income country that doesn’t provide access to necessary healthcare. The state of Mississippi remains one of the poorest states in the United States. This has resulted in poor health outcomes and chronic access barriers. Residents of Mississippi ranks poorly in most health indicators, including Infectious Disease, Infant Mortality, Clinic Care, Obesity, Diabetes, and Premature Death.

With half of all rural hospitals in Mississippi threatened with closure, access and quality of care barriers will become more challenging to resolve. This comes partly as a result of the state largely governed by Republicans and the legislators refusing to …

The Privacy Preserving Framework With Virtual Ring And Identity-Based Cryptography For Smart Grid, Leonard Sutanto

Publications and Research

One of the main challenges in the smart grid is how to efficiently manage the high-volume data from smart meters and sensors and preserve the privacy from the consumption data to avoid potential attacks (e.g., identity theft) for the involved prosumers, retail electricity providers and other clusters of distributed energy resources. This poster proposes a two-layer framework with the cloud computing infrastructure. The virtual ring and identity-based cryptography are utilized in each layer to preserve privacy efficiently. The methods of the virtual ring and identity-based cryptography are introduced. The purposes and needs are discussed at the end of this poster.

The Disconnect Between Family Law And Immigration Law In The Usa That Results In Undocumented Immigrants Losing Parental Rights, Mercedes Aznar, Sara Schechter

Publications and Research

Due to increasing violence in Latin American countries, the flow of immigrants seeking asylum in the United States has risen. In our research we look into possible legal consequences of the practice of separating immigrant families. Through the analysis of scholarly articles and legal documents we found that oftentimes, undocumented immigrants lose parental rights while being detained by the Immigration and Customs Enforcement (ICE), due to lack of coordination between Family Law and Immigration Law. Findings in this study reinforce the urgency to find solutions to this problem.

The Psychology Of Hurricane Warnings: Why They Are Sometimes Ignored, Christina Bhawanidin

Publications and Research

Why do some people heed evacuation orders given before an impending major disaster such as a hurricane, while others do not? Failure to comply with departure instructions puts the individual at personal peril, as well as the first responders responsible for rescue and evacuation during those dangerous times. For example, during Hurricane Sandy in New Jersey, 72% of people refused to evacuate their homes, whereas during Hurricane Rita in the Gulf of Mexico, 53% of people disobeyed orders to evacuate. The purpose of this research is to begin the process of investigating the psychological factors that contribute to individual differences …

Children’S Gender And Investments From Nonresident Fathers, Kristin Mammen

Publications and Research

Evidence suggests that fathers have stronger ties to sons than daughters, which may result in differential investments in their children. This paper investigated whether girls’ gender restricts their access to fathers' contributions if they do not live together. The data used were the 1994-2008 March/April Match Current Population Survey Child Support Supplements, a large, nationally representative sample which identifies child support eligible mothers of all marital statuses and collects information on nonresident fathers’ financial and social investments in their children. Results for court-mediated outcomes such as the existence and amounts of child support orders showed that courts do not allocate …

College Students And Snap: The New Face Of Food Insecurity In The United States, Nicholas Freudenberg, Sara Goldrick-Rab, Janet Poppendieck

Publications and Research

Over the last decade, multiple studies of food insecurity among college students have found rates from 20% to more than 50%, considerably higher than the 12% rate for the entire US population.

Reasons for higher rates of food insecurity among college students include a growing population of low-income college students, high college costs and insufficient financial aid, more financial hardship among many low- and moderate-income families, a weak labor market for part-time workers, declining per capita college resources, and Supplemental Nutritional Assistance Program (SNAP) policies that specifically exclude many college students from participation.

This essay reviews the causes and consequences …

Please Tweet Responsibly: The Social And Professional Ethics Of Public Defenders Using Client Information In Social Media Advocacy, Nicole Smith Futrell

Publications and Research

Every day the criminal legal system hauls poor and marginalized individuals through a process wrought with trauma, indignity, and abuse. Public defenders representing the criminally accused view their clients and the system from a unique vantage point: they bear witness to the human costs of a system that falls far short of its purported norms and ideals. For the public defender who works within this reality day in and day out, fighting for each individual client might feel limited in its wider impact. Some public defenders have found that using online and social media platforms, such as Twitter, to provide …

Dominy, Tony Goldberg, Joanna E. Lambert, Larissa Swedell, Jessica L. Metcalf, Andres Gomez, Gillian A. O. Britton, Rebecca M. Stumpf, Steven R. Leigh, Rob Knight

Publications and Research

Background

Comparative data from non-human primates provide insight into the processes that shaped the evolution of the human gut microbiome and highlight microbiome traits that differentiate humans from other primates. Here, in an effort to improve our understanding of the human microbiome, we compare gut microbiome composition and functional potential in 14 populations of humans from ten nations and 18 species of wild, non-human primates.

Results

Contrary to expectations from host phylogenetics, we find that human gut microbiome composition and functional potential are more similar to those of cercopithecines, a subfamily of Old World monkey, particularly baboons, than to those …

The Fusions And Confusions Of The Concierto De Aranjuez In Jazz: A Listener’S Musings, Antoni Pizà

Publications and Research

Reflections on Sketches of Spain (1960) by Miles Davis and Gil Evans, focusing on their jazz version of Joaquín Rodrigo’s Concierto de Aranjuez (1940). Motivated by Edward Said’s and Homi K. Bhabha’s writings, the recording is analyzed as a cultural artifact characterized by its “formal instability” and its typological “inbetweenness,” rendering it neither classical nor jazz; neither Spanish nor non-Spanish; and neither traditional nor modern, among other dualities. Sketches is an artwork that defies categories and inhabits the interstices of cultural expectations.

Case Presentation On Urinary Bladder Cancer And Cysto-Prostatectomy, Tetiana Soloviova

Publications and Research

Patients who have invasive bladder cancer (spread to different tissues and organs) may need to have a radical cystectomy type of surgery. In male patients, the surgeon usually removes the prostate and seminal vesicles in addition to the bladder, parts of the ureters, and lymph nodes (Nicholson, 2017, ¶ 1)

In our case a reconstructive surgery followed right after removing of the bladder and prostate gland. A different way of urine to be stored and passed from the patient’s body was created by the surgeon. A part of small intestine was used to make up a reservoir that will serve …

Static Solid Relaxation Ordered Spectroscopy: Ss-Rosy, Gregory S. Boutis, Ravinath Kausik

Publications and Research

A two-dimensional pulse sequence is introduced for correlating nuclear magnetic resonance anisotropic chemical shifts to a relaxation time (e.g., T1) in solids under static conditions. The sequence begins with a preparatory stage for measuring relaxation times, and is followed by a multiple pulse sequence for homonuclear dipolar decoupling. Data analysis involves the use of Fourier transform, followed by a one-dimensional inverse Laplace transform for each frequency index. Experimental results acquired on solid samples demonstrate the general approach, and additional variations involving heteronuclear decoupling and magic angle spinning are discussed.

Private Security And Cctv Surveillance: A Systematic Review Of Function And Performance, Brandon C. Welsh, Eric L. Piza, Amanda L. Thomas, David P. Farrington

Publications and Research

Private security personnel play an important but largely overlooked role in the operation of CCTV surveillance to prevent crime in public and private areas. This role can take a number of forms, including active monitoring of cameras. Drawing upon a global database of CCTV evaluations (N=165), this article examines the function and performance of private security personnel as related to the effectiveness of CCTV. Findings indicate that CCTV schemes operated by private security personnel generated larger crime prevention effects than those operated by police or those using a mix of police and security personnel. Policy and research implications are discussed.

Graded Quivers, Generalized Dimer Models And Toric Geometry, Sebastián Franco, Azeem Hasan

Publications and Research

The open string sector of the topological B-model on CY (m+2)-folds is described by m-graded quivers with superpotentials. This correspondence extends to general m the well known connection between CY (m+2)-folds and gauge theories on the world-volume of D(5-2m)-branes for m = 0, ..., 3. We introduce m-dimers, which fully encode the m-graded quivers and their superpotentials, in the case in which the CY (m+2)-folds are toric. Generalizing the well known m = 1,2 cases, m-dimers significantly simplify the connection between geometry and m-graded quivers. A key …

Background:

Men who have sex with men (MSM) continue to be the predominately impacted risk group in the United States HIV epidemic and are a priority group for risk reduction in national strategic goals for HIV prevention. Modeling studies have demonstrated that a comprehensive package of status-tailored HIV prevention and care interventions have the potential to substantially reduce new infections among MSM. However, uptake of basic prevention services, including HIV testing, sexually transmitted infection (STI) testing, condom distribution, condom-compatible lubricant distribution, and preexposure prophylaxis (PrEP), is suboptimal. Further, stronger public health strategies are needed to promote engagement in HIV care …
