Tourism-Related Climate Change Perspectives: Social Media Conversations About Canada’S Rocky Mountain National Parks, Farshid Mirzaalian, Elizabeth Halpenny Jul 2021

Tourism-Related Climate Change Perspectives: Social Media Conversations About Canada’S Rocky Mountain National Parks, Farshid Mirzaalian, Elizabeth Halpenny

TTRA Canada 2021 Conference

This study employed quantitative social media big data analysis in conjunction with qualitative analysis of postings to better comprehend online lay discourse of climatic change issues in a nature-based tourism destination, Jasper National Park, Canada. Such mixed methodological approaches to big data enable tourism researchers to not only study unstructured social media big data for future-proofing purposes but to address some methodological concerns often raised about solely using corpus linguistic or thematic analyzes. This study unearthed divergent themes regarding tourists’ perceptions of climate change upon visiting JNP, with the most significant discourses on climate grief, education and interpretation, pro- environmental …


Probabilistic Models For Identifying And Explaining Controversy, Myungha Jang Jul 2019

Probabilistic Models For Identifying And Explaining Controversy, Myungha Jang

Doctoral Dissertations

Navigating controversial topics on the Web encourages social awareness, supports civil discourse, and promotes critical literacy. While search of controversial topics particularly requires users to use their critical literacy skills on the content, educating people to be more critical readers is known to be a complex and long-term process. Therefore, we are in need of search engines that are equipped with techniques to help users to understand controversial topics by identifying them and explaining why they are controversial. A few approaches for identifying controversy have worked reasonably well in practice, but they are narrow in scope and exhibit limited performance. …

The Billion Object Platform (Bop): A System To Lower Barriers To Support Big, Streaming, Spatio-Temporal Data Sources, Devika Kakkar, Ben Lewis, David Smiley, Ariel Nunez

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

With funding from the Sloan Foundation and Harvard Dataverse, the Harvard Center for Geographic Analysis (CGA) has developed a big spatio-temporal data visualization platform called the Billion Object Platform or "BOP". The goal of the project is to lower barriers for scholars who wish to access large, streaming, spatio-temporal datasets. Since once archived, streaming data gets big fast, and since most GIS systems don't support interactive visualization of millions of objects, a new platform was needed. The BOP is loaded with the latest billion geo-tweets and is fed a real-time stream of about 1 million tweets per day. The CGA …

Rescuing biochar: Pre - application techniques to enhance plant responses to biochar additions: Nigel Gale, U of Toronto

A growing body of literature indicates variable responses of different plant species to biochar, including positive, neutral, and negative, suggesting that it is important to investigate the nature and mechanism of species-specific responses to biochar additions. Neutral or negative plant responses to additions of biochars have commonly been reported in prior studies, and are likely the result of a combination of changes in soil properties (e.g. pH, surface area, and nutrient and water retention) and the production of volatile organic compounds from …

Cascading Uses of Biochar - Hans-Peter Schmidt, Ithaka Institute

In addition to the use of biochar as a soil amendment, there are an increasing number of ways to incorporate biochar into different eco- and industrial systems. Thus feeding biochar to livestock has numerous benefits not only for the animals, but it also helps reduce greenhouse gas emissions and improves nutrient retention in animal manure. The use of biochar in building materials is just beginning to be studied but shows promise in the ability to insulate, decontaminate air, provide odor and humidity control. Biochar as pillow filling to induce perfectly reposing …

Ethics & Sustainability, Gloria Flora, John Bonitz, Karen Ribeiro

USBI Biochar Conferences

Biochar and the Sustainability Imperative. Now marks a critical time: as biochar comes of age and markets begin to develop, this young industry is attracting naysayers, doubters and get-rich-quick-schemers. Ethical biochar production and use is of paramount importance as we continue to lay the groundwork for biochar as a model for carbon neutral/negative business, landscape restoration and truly green technology. Shortcuts, poor quality product and unsustainable use of biomass could bring biochar to its knees before it gains the traction necessary to fulfill its promises. This discussion will explore opportunities and pitfalls in feedstocks sustainability, production integrity and ethics in …

Sorptive Treatment of Metals and Nitro Explosives in Water Using Biochar -

Seok-Young Oh1*,

Biochar, a solid byproduct of a pyrolysis process was investigated as a sorbent to remove toxic metals and nitro explosives from natural water and wastewater. It was hypothesized that biochar can sorb dissolved metals and nitro explosives due to its high surface area and strong sorption affinity of aromatic organic compounds. Using a tube furnace under N2, various types biochar were synthesized by changing biomass (poultry litter, sludge, fallen leaves, corn stalk, rice straw, and coffee grounds) and temperature (250, 400, …

Cultural Discourse Of Dwelling: Environmental Comunication As A Place-Based Practice, Donal Carbaugh Jan 2013

Cultural Discourse Of Dwelling: Environmental Comunication As A Place-Based Practice, Donal Carbaugh

Donal Carbaugh

In this essay we contribute a response to intellectual and practical problems by using and developing a perspective on environmental communication that is reflexively grounded in place and that explores human relations with nature, while embracing cultural and linguistic variability in these processes. Our goals are to introduce a way to think through communication to places, and further to link that understanding to issues of engaged environmental action, to deeply seated notions of identity, and to the affective dimension of belonging that place-based communication often brings with it. Our way of doing this is to theorize and study cultural discourses …

Ethical Problems And Dilemmas In The Interaction Between Science And Media, David Resnik Jul 1996

Ethical Problems And Dilemmas In The Interaction Between Science And Media, David Resnik

Ethics in Science and Engineering National Clearinghouse

Science and the media are not strange bedfellows since they both gather information, value accuracy and objectivity, and recognize their enormous social responsibilities. The public often benefits from interactions between science and the media, and these two institutions often complement each other. However, since they have different standards, goals, expertises, competencies, and funding sources, science and the media can sometimes interact in ways that produce unintended, adverse consequences for the public. Sometimes the public may become misinformed, deceived, or confused as a result of the media's coverage of science. This unfortunate effect can lead to poor policy decisions, ill-informed public …
