Toward An Educational Sphereology: Air, Wind, And Materialist Pedagogy, Derek R. Ford

Education Studies Faculty publications

It’s not uncommon for people to make reference to atmospheres, including in relationship with educational spaces. In this article, we investigate educational atmospheres by turning to Western and Chinese literature on the air and wind. We pursue this task in three phases. First, we examine the Western literature to see the possible strings of thought that would help us reinvigorate the element of air/atmosphere as a foundational component of an educational sphere. Second, we historicize the Chinese notion of wind as a style of reasoning which structures ancient Chinese cosmology, tempo-spatiality, teaching, and governing into a grid of intelligibility. Third, …

Children's Exposure To Food Advertising On Free-To-Air Television: An Asia-Pacific Perspective, Bridget Kelly, Lana Hebden, Lesley King, Yang Xiao, Yang Yu, Gengsheng He, Liangli Li, Lingxia Zeng, Hamam Hadi, Tilakavati Karupaiah, Ng See Hoe, Mohd Ismail Noor, Jihyun Yoon, Hyogyoo Kim

Faculty of Social Sciences - Papers (Archive)

There is an established link between food promotions and children's food purchase and consumption. Children in developing countries may be more vulnerable to food promotions given the relative novelty of advertising in these markets. This study aimed to determine the scope of television food advertising to children across the Asia-Pacific to inform policies to restrict this marketing. Six sites were sampled, including from China, Indonesia, Malaysia and South Korea. At each site, 192 h of television were recorded (4 days, 16 h/day, three channels) from May to October 2012. Advertised foods were categorized as core/healthy, non-core/unhealthy or miscellaneous, and by …

Evaluation Of Inorganic Arsenic Exposure At Multi Metal Processing Facility. When Air Monitoring Alone Just Doesn't Work!, Stuart J. Roseberg, Jane L. Whitelaw

Faculty of Social Sciences - Papers (Archive)

Metals smelting and processing has been associated with exposure to airborne inorganic arsenic and an increased risk of health effects. Biological monitoring on a metals processing site identified urinary arsenic concentrations exceeding corporate and ACGIH guidelines at levels associated with increased risks of health effects. Plant operators considered the inhalation of arsenic trioxide powder (As2O3), used in the process, as the source of their exposure. This study's initial objective was to determine operator exposures to airborne inorganic arsenic. Two groups of plant operators participated in full shift personal air monitoring and biological monitoring over their working weeks. In parallel, wipe …

The Pneumatic Common: Learning In, With And From The Air, Derek R. Ford

Education Studies Faculty publications

Air is an immersive substance that envelopes us and binds us together, yet it has dominantly been taken for granted and left out of educational and other theorizations. This article develops a conceptualization of the pneumatic common in order to address this gap. The specific intervention staged is within recent educational literature on the common by Noah De Lissovoy, Tyson E. Lewis, and Alexander Means. This literature is surveyed and analyzed in relation to educational theory, curriculum, pedagogy, and policy. Claiming that the air is a central feature of and paradigm for the common, I then concentrate on making the …

Effect Of Air Pollution And Racism On Ethnic Differences In Respiratory Health Among Adolescents Living In An Urban Environment, Thomas E. Astell-Burt, Maria J. Maynard, Erik Lenguerrand, Melissa Whitrow, Oarabile R. Molaodi, Seeromanie Harding

Faculty of Social Sciences - Papers (Archive)

Recent studies suggest that stress can amplify the harm of air pollution. We examined whether experience of racism and exposure to particulate matter with an aerodynamic diameter of less than 2.5 µm and 10 µm (PM_2.5 and PM₁₀) had a synergistic influence on ethnic differences in asthma and lung function across adolescence. Analyses using multilevel models showed lower forced expiratory volume (FEV₁), forced vital capacity (FVC) and lower rates of asthma among some ethnic minorities compared to Whites, but higher exposure to PM_2.5, PM₁₀ and racism. Racism appeared to amplify the relationship …

Development Of In Vitro Methods For Toxicity Testing Of Workplace Air Contaminants, Shahnaz Bakand, Amanda Hayes, Chris Winder

Faculty of Social Sciences - Papers (Archive)

While the OECD test guidelines and mostly animal assays have been used to study the toxic effects of chemicals for many years, very little is known about the potential toxicity of vast majority of inhaled chemicals. Considering large number of chemicals and complex mixtures present in indoor and outdoor air, heavy reliance on animal test methods appear to be not adequate. Continuing scientific developments are needed to improve the process of safety evaluation for the vast number of chemicals and inhaled materials. The aim of this study was to optimise in vitro methods for toxicity testing of airborne contaminants. An …

Nf05-631 Understanding Watersheds, Thomas G. Franti, Steven R. Tonn

University of Nebraska-Lincoln Extension: Historical Materials

Watersheds are dynamic and unique places. They are complex webs of natural resources, — soil, water, air, plants and animals. Together land and water make a watershed a whole system.

This NebFacts covers what a watershed is, how it works, its functions, how human activities can alter watershed functions, and its management.

G00-1404 Radon In Nebraska Homes: Healthy Indoor Air For Healtlhy Nebraskans (Revised October 2003), Rebecca L. Versch, Shirley Niemeyer

University of Nebraska-Lincoln Extension: Historical Materials

Radon is a colorless, odorless, radioactive gas emitted from uranium, a naturally occurring mineral in rocks and soil. Normally, radon rises up through the soil and then dissipates in the air outside. Radon becomes a concern, however, when it seeps in through openings such as cracks, loose-fitting pipes, sump pits, dirt floors, slab joints, or block walls and accumulates in the home.

This publication will help householders understand radon — what it is, its effect on heatlh, how to test for it, and some remodeling or new building techniques that can reduce radon levels in the home.

G85-760 Natural Air Corn Drying, Richard O. Pierce, Thomas L. Thompson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses factors affecting natural air corn drying system performance, and gives recommendations for bins filled over a one- to two-day period.

Natural air drying is an energy efficient drying method that is particularly well suited to Nebraska weather conditions. A high quality dried product, with little of the stress cracking or heat damage associated with high temperature drying, is an added attraction. However, good management practices must be followed to achieve satisfactory drying results.

A major concern with this method is overloading the bin with corn too wet to be dried without spoilage or deterioration, especially when the …

G75-282 Emergency Wind Erosion Control (Revised March 1992), John A. Smith, Drew J. Lyon, Elbert C. Dickey, Philip Rickey

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide covers temporary techniques for emergency wind erosion control, when time and prior planning don't allow soil or seedlings adequate protection using more desirable methods. Soil erosion by wind is a serious threat to growing crops, our land resource, and the air we breathe. The best solution to soil erosion is long-term planning. Recommended practices include residue or crop cover, strip cropping, and windbreaks. These practices are known to substantially reduce wind erosion in even the most extreme conditions. However, conditions sometimes occur when serious soil erosion is imminent or has just begun, and corrective action is required to …
