Simulation Insights Using R, Boyan Kostadinov

Publications and Research

This article attempts to introduce the reader to computational thinking and solving problems involving randomness. The main technique being employed is the Monte Carlo method, using the freely available software R for Statistical Computing. The author illustrates the computer simulation approach by focusing on several problems of increasing difficulty. The simulation techniques and the specific problems discussed in this article would be of interest to STEM students and instructors, teaching courses in Monte Carlo simulations, stochastic modeling, probability and statistics. The R code for all problems is discussed in full detail so that the reader can get a taste of …

Comprehensive Self-Study Submitted By President Jeremy Travis To The Middle States Commission On Higher Education, March 2013., John Jay College Of Criminal Justice

Reports and Publications from John Jay College

Our Self-Study tells a story of institutional transformation. It is not a story driven by accidental circumstances, historical necessity, external forces, or the will of an individual—though each has played a role—but by collective and deliberate analysis of the College’s position in 2005, followed by thoughtful consideration of the future. Institutional change is often, if not always, difficult, but we have learned to pay constant attention to the ever-changing environment and the fixed destination. We have taken advantage of the opportunity offered by the Self-Study to reflect on the past and look toward the future.

Transcranial Electrical Stimulation Accelerates Human Sleep Homeostasis, Davide Reato, Fernando Gasca, Abhishek Datta, Marom Bikson, Lisa Marshall, Lucas C. Parra

Publications and Research

The sleeping brain exhibits characteristic slow-wave activity which decays over the course of the night. This decay is thought to result from homeostatic synaptic downscaling. Transcranial electrical stimulation can entrain slow-wave oscillations (SWO) in the human electro-encephalogram (EEG). A computational model of the underlying mechanism predicts that firing rates are predominantly increased during stimulation. Assuming that synaptic homeostasis is driven by average firing rates, we expected an acceleration of synaptic downscaling during stimulation, which is compensated by a reduced drive after stimulation. We show that 25 minutes of transcranial electrical stimulation, as predicted, reduced the decay of SWO in the …

Allometric Scaling And Resource Limitations Model Of Tree Heights: Part 1. Model Optimization And Testing Over Continental Usa, Yuli Shi, Sungho Choi, Xiliang Ni, Sangram Ganguly, Gong Zhang, Hieu V. Duong, Michael A. Lefsky, Marc Simard, Sassan S. Saatchi, Shihyan Lee, Wenge Ni-Meister, Shilong Piao, Chunxiang Cao, Ramakrishna R. Nemani, Ranga B. Myneni

Publications and Research

A methodology to generate spatially continuous fields of tree heights with an optimized Allometric Scaling and Resource Limitations (ASRL) model is reported in this first of a multi-part series of articles. Model optimization is performed with the Geoscience Laser Altimeter System (GLAS) waveform data. This methodology is demonstrated by mapping tree heights over forested lands in the continental USA (CONUS) at 1 km spatial resolution. The study area is divided into 841 eco-climatic zones based on three forest types, annual total precipitation classes (30 mm intervals) and annual average temperature classes (2 °C intervals). Three model parameters (area of single …

Estimation Of Total Body Skeletal Muscle Mass In Chinese Adults: Prediction Model By Dual-Energy X-Ray Absorptiometry, Xinyu Zhao, Zimian Wang, Junyi Zhang, Jianming Hua, Wei He, Shankuan Zhu

Publications and Research

Background: There are few reports on total body skeletal muscle mass (SM) in Chinese. The objective of this study is to establish a prediction model of SM for Chinese adults.

Methodology: Appendicular lean soft tissue (ALST) was measured by dual energy X-ray absorptiometry (DXA) and SM by magnetic resonance image (MRI) in 66 Chinese adults (52 men and 14 women). Images of MRI were segmented into compartments including intermuscular adipose tissue (IMAT) and IMAT-free SM. Regression was used to fit the prediction model SM~czk|ALST. Age and gender were adjusted in the fitted model. The piece-wise linear function was performed to …

From Toxic Tours To Growing The Grassroots: Tensions In Critical Pedagogy And Community Development, Celina Su, Isabelle Jagninski

Publications and Research

Structural inequalities in American public education are inextricably tied to deep-seated patterns of racial and economic segregation. Children in poor neighborhoods are less likely to have the household resources, neighborhood institutions, or school amenities necessary for a good, challenging education. In response, a growing number of organizations have launched initiatives to simultaneously revitalize neighborhoods and improve public education, emphasizing youth participation as an essential component in their efforts. We draw upon ethnographic data from two such organizations to examine their practice of place-based critical pedagogy in community development. We focus on how they engage marginalized, “hard-to-reach” youth via (1) experiential …
