The Use Of Repurposed Whole Textiles To Modify The Mechanical And Hydrogeological Properties Of Green Roof Media And Granular Soils, Angelis Almanzar-Chevalie, Yehya Elfgeeh, Calvin O. Walters Jr. May 2024

The Use Of Repurposed Whole Textiles To Modify The Mechanical And Hydrogeological Properties Of Green Roof Media And Granular Soils, Angelis Almanzar-Chevalie, Yehya Elfgeeh, Calvin O. Walters Jr.

Publications and Research

This study investigates using repurposed whole textiles to modify the mechanical and hydrogeological properties of lightweight Green Roof media and granular pavement soils.

Green Roof Media Green roofs aim to bring the advantages of suburban agriculture to urban environments while improving energy efficiency and enhancing stormwater management in public, commercial, and residential buildings. Previous studies by City Tech undergraduate research assistants demonstrated significant modification in hydrogeological properties when incorporating textile fabric up to 3% textile by weight (%Tex) at an aspect ratio of 1:1. The effects of mixing repurposed whole textile fiber with Green Roof media is evaluated with regards …


21st Century Ecopoetics And Ecotheory, Robert Balun Jul 2021

21st Century Ecopoetics And Ecotheory, Robert Balun

Open Educational Resources

Ecopoetics is the study of literature that is concerned with ecology and nature. However, beyond just literature about nature, this course will examine how ecology and nature have become complicated in the 21st century, the age of the Anthropocene, the age of the climate crisis and the 6th mass extinction (don’t worry, we will define these and other key terms).

In the 21st century, humans are now confronted with a growing awareness of their destructive impact on the earth, its environments, and its human and non-human inhabitants. In this class we will examine how ecology and nature have become complicated …


A Review Of Measuring Ecosystem Resilience To Disturbance, Chuixiang Yi, Nathan Jackson Jan 2021

A Review Of Measuring Ecosystem Resilience To Disturbance, Chuixiang Yi, Nathan Jackson

Publications and Research

Resilience is the central concept for understanding how an ecosystem responds to a strong perturbation, and is related to other concepts used to analyze system properties in the face of change such as resistance, recovery, sustainability, vulnerability, stability, adaptive capacity, regime shift, and tipping point. It is extremely challenging to formulate resilience thinking into practice. The current state-of-art approaches of assessing ecosystem resilience may be useful for policy makers and ecosystem resource managers to minimize climatological or natural disaster related impacts. Here, we review the methods of assessing resilience and classify and limit them to three cases: (1) forest resilience …


Past, Present, And Future Of Waste Cooking Oil (Beyond Biofuel), Jihyun Kim Jan 2019

Past, Present, And Future Of Waste Cooking Oil (Beyond Biofuel), Jihyun Kim

Open Educational Resources

In this project, students in “General Chemistry” will explore the development of a facile, eco-friendly, and simple preparation method of fluorescent carbon dots (CDs) from a mixture of waste cooking oil and orange waste peels. Orange waste peels are one of the most underutilized bio-waste residues on earth, therefore, it would make better sense to utilize a mixture of the two wastes.

Cultivating a more dynamic relationship between science and policy is essential for responding to complex social challenges such as sustainability. One approach to doing so is to “span the boundaries” between science and decision making and create a more comprehensive and inclusive knowledge exchange process. The exact definition and role of boundary spanning, however, can be nebulous. Indeed, boundary spanning often gets conflated and confused with other approaches to connecting science and policy, such as science communication, applied science, and advocacy, which can hinder progress in the field of boundary spanning. To help overcome this, in this perspective, we present …


Social Science Perspectives On Drivers Of And Responses To Global, Andrew K. Jorgenson, Shirley Fiske, Klaus Hubacek, Jia Li, Tom Mcgovern, Torben Rick, Juliet B. Schor, William Solecki, Richard York, Ariela Zycherman Jan 2018

Social Science Perspectives On Drivers Of And Responses To Global, Andrew K. Jorgenson, Shirley Fiske, Klaus Hubacek, Jia Li, Tom Mcgovern, Torben Rick, Juliet B. Schor, William Solecki, Richard York, Ariela Zycherman

Publications and Research

This article provides a review of recent anthropological, archeological, geographical, and sociological research on anthropogenic drivers of climate change, with a particular focus on drivers of carbon emissions, mitigation and adaptation. The four disciplines emphasize cultural, economic, geographic, historical, political, and social‐structural factors to be important drivers of and responses to climate change. Each of these disciplines has unique perspectives and makes noteworthy contributions to our shared understanding of anthropogenic drivers, but they also complement one another and contribute to integrated, multidisciplinary frameworks. The article begins with discussions of research on temporal dimensions of human drivers of carbon emissions, highlighting …


Age And Employee Green Behaviors: A Meta-Analysis, Brenton M. Wiernik, Stephan Dilchert, Deniz S. Ones Mar 2016

Age And Employee Green Behaviors: A Meta-Analysis, Brenton M. Wiernik, Stephan Dilchert, Deniz S. Ones

Publications and Research

Recent economic and societal developments have led to an increasing emphasis on organizational environmental performance. At the same time, demographic trends are resulting in increasingly aging labor forces in many industrialized nations. Commonly held stereotypes suggest that older workers are less likely to be environmentally responsible than younger workers. To evaluate the degree to which such age differences are present, we meta-analyzed 132 independent correlations and 336 d-values based on 4676 professional workers from 22 samples in 11 countries. Contrary to popular stereotypes, age showed small positive relationships with pro-environmental behaviors, suggesting that older adults engaged in these workplace …


Sustainability Of Dual Water Distribution Systems For Fire Flow Condition, Nazli Yonca Aydin, Larry Mays, Theo G. Schmitt Aug 2014

Sustainability Of Dual Water Distribution Systems For Fire Flow Condition, Nazli Yonca Aydin, Larry Mays, Theo G. Schmitt

International Conference on Hydroinformatics

The objective of this study is to compare the sustainability of current water systems when a dual water distribution system (WDS) is used for the non-potable water purposes of fire protection, irrigation, and toilet flushing. Sustainability of urban WDS is evaluated in terms of hydraulic efficiency and water quality. The first step is to assess sustainability of an example urban WDS by using sustainability index (SI). The SI is measured by reliability, resiliency, and vulnerability performance indices. Pressure and water age are selected as main parameters to determine sustainability. Once the SIs for pressure and water age are calculated by …
