Understanding Students’ Global Interdependence In Science Instruction, Walter S. Smith 2021 Texas Tech University

Understanding Students’ Global Interdependence In Science Instruction, Walter S. Smith

Journal of Global Education and Research

Multiple American educational organizations such as the National Education Association, Association for Supervision and Curriculum Development, and the Council of Chief State School Officers have advocated for globalizing the K-12 curriculum. The National Science Teaching Association (NSTA) in a position statement on international education and the Next Generation Science Standards have produced goals and standards for internationalizing the science curriculum by addressing topics such as climate change, environment, and disease that cross borders. In contrast to those pronouncements on the curriculum, this article views global science education through an instructional lens that focuses on a students’ global interdependence in science ...


Waste To Phosphorus: A Transdisciplinary Solution To P Recovery From Wastewater Based On The Triz Approach, Anna Jama-Rodzeńska, Andrzej Białowiec, Jacek A. Koziel, Józef Sowiński 2021 Wroclaw University of Environmental and Life Sciences

Waste To Phosphorus: A Transdisciplinary Solution To P Recovery From Wastewater Based On The Triz Approach, Anna Jama-Rodzeńska, Andrzej Białowiec, Jacek A. Koziel, Józef Sowiński

Agricultural and Biosystems Engineering Publications

Phosphorus (P) is a limited yet essential resource. P cannot be replaced, but it can be recovered from waste. We proposed the TRIZ approach (Teoria reszenija izobretatielskich zadacz - Rus., Theory of Inventive Problem Solving - Eng.) to identify a feasible solution. We aimed at minimizing the environmental impact and, by eliminating contradictions, proposed viable technical solutions. P recovery can be more sustainable based on circular economy and 4Rs (reduction, recovery, reuse, and recycling). The TRIZ approach identified sewage sludge (SS) as waste with a large potential for P recovery (up to 90%). Successful selection and application of SS management and P ...

Can’T Bear It! Employing Culturally Sensitive Initiatives To Reduce Bear Bile Demand In Northern Vietnam, Alicia Ngo, Shannon Randolph

EnviroLab Asia

Over the past 30 years, the combination of over-hunting, habitat loss, and increased bear bile demand has caused significant declines in Asiatic black bear (aka moon bear; Ursus thibetanus) and sun bear (Helarctos malayanus) populations. In Eastern medicine, bear bile is extracted from the gallbladders of bears and is then used to treat a wide range of inflammatory, liver, and degenerative ailments. However, the use of bear bile has had significant impacts on bear populations. Given that communities in Northern Vietnam have a lengthy history of using bear bile and bear bile is easily accessible, merely advocating for wildlife conservation ...

Assessing The Impacts To Society Associated With The Use Of Alternative Ammunition For Hunting On National Wildlife Refuges, Christopher Cahill 2021 University of Massachusetts Amherst

Assessing The Impacts To Society Associated With The Use Of Alternative Ammunition For Hunting On National Wildlife Refuges, Christopher Cahill

Masters Theses

Attempts to eliminate lead ammunition use for hunting through regulatory approaches can be controversial and contentious, despite extensive scientific evidence of the detrimental effect of lead on wildlife species. In the United States, voluntary approaches to non-lead use that have used outreach and education in place of regulatory approaches have achieved sustained behavioral change in hunter ammunition choice. However, voluntary approaches to alternative ammunition use can be confronted with both practical and social barriers. In collaboration with U.S. Fish and Wildlife Service and U.S. Geological Survey Cooperative Research Units Program, this study assessed the practical and social barriers ...

Pecan shells are a rich source of various bioactive compounds with potential antioxidant and antimicrobial properties. This study investigated the effect of pecan variety and method extraction on the antioxidant property of shell extracts. Twenty different varieties of pecan shells were subjected to either aqueous or ethanolic extraction and were examined for total phenolics and antiradical activity. The phenolic content and antiradical activity of shell extracts were significantly (p < 0.05) varied with different pecan cultivars. The total phenolic content of ethanol extracts ranged from 304.2 (Caddo) to 153.54 (Cherokee) mg GAE/g of dry extract and was significantly greater (p < 0.05) than those obtained by aqueous extraction. The antiradical activity of ethanol extracts ranged from 840.6 (Maramec) to 526.74 (Caper Fear) mg TEg−1, while aqueous extracts ranged from 934.9 (Curtis) to 468.3 (Elliot) mg TEg−1. Chemical profiling of the crude and acid hydrolyzed extracts was performed by reverse phase high performance liquid chromatography and flow injection electrospray ionization mass spectrometry. Lignin degradation products such as lignols, dilignols, trilignols, and oligolignols were found to be the major components of tested extracts. Phenolic content and antiradical activity of pecan shell extracts are significantly varied with cultivars and methods of extraction.

Bulletin of Chinese Academy of Sciences (Chinese Version)

Micro-organisms such as bacteria, archaea, and viruses are an immense invisible driving force behind the ocean carbon cycle and play a pivotal role in global climate change. Atmospheric CO2 is transformed into depositing organic components with the help of marine planktonic organisms which act as a biological pump (BP). The labile organic components are then transformed into recalcitrant organic carbon (RDOC) through the action of bacteria, archaea, and other organisms and viruses, which are called the microbial carbon pump (MCP). RDOC can be stored over thousands of years in the water column and the accompanying particulate organic matter can further ...

Coral Reefs: Potential Blue Carbon Sinks For Climate Change Mitigation, Tuo Shi, Xinqing Zheng, Han Zhang, Qifang Wang, Xin Zhong

Bulletin of Chinese Academy of Sciences (Chinese Version)

Coral reefs are one of the most productive, and yet most vulnerable marine ecosystems. The global decline of coral reefs induced by climate change and human activities has already affected the processes of coral calcification and carbon cycling in the reef ecosystem, intensifying the long-standing CO2 "source-sink" debate over coral reefs. Despite the fact that coral calcification is accompanied by the release of CO2 to the atmosphere, the significance of coral reefs as a carbon sink cannot be ignored, given the complex biogeochemical processes in the reef ecosystem and the characteristic mixotrophic lifestyle of the reef-building corals. From the perspective ...
