Symmetry And Measuring: Ways To Teach The Foundations Of Mathematics Inspired By Yupiaq Elders, Jerry Lipka, Barbara Adams, Monica Wong, David Koester, Karen Francois Jan 2019

Symmetry And Measuring: Ways To Teach The Foundations Of Mathematics Inspired By Yupiaq Elders, Jerry Lipka, Barbara Adams, Monica Wong, David Koester, Karen Francois

Journal of Humanistic Mathematics

Evident in human prehistory and across immense cultural variation in human activities, symmetry has been perceived and utilized as an integrative and guiding principle. In our long-term collaborative work with Indigenous Knowledge holders, particularly Yupiaq Eskimos of Alaska and Carolinian Islanders in Micronesia, we were struck by the centrality of symmetry and measuring as a comparison-of-quantities, and the practical and conceptual role of qukaq [center] and ayagneq [a place to begin]. They applied fundamental mathematical principles associated with symmetry and measuring in their everyday activities and in making artifacts. Inspired by their example, this paper explores the question: Could symmetry ...


Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith Nov 2017

Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith

Daryl Smith

Iowa's prairie has to be assessed in the context of the pre- and post-agriculturally dominated ecosystem in which it now exists. This requires an understanding of prairies and of society's perspective of prairies. Therefore, the attitudes of people through time have to be considered; (1) those who were involved in the demise of the prairie, (2) those who helped saved the pieces of the prairie and (3) those who may be called upon to recover the prairie ecosystem.


The Pedagogical Needs Of Children And Adults Living In The Calais Jungle Refugee Camp: Existential Issues And Perspectives Of Volunteer Teachers And Workers, Theresa C. Bodon, Nancy K. Votteler Sep 2017

The Pedagogical Needs Of Children And Adults Living In The Calais Jungle Refugee Camp: Existential Issues And Perspectives Of Volunteer Teachers And Workers, Theresa C. Bodon, Nancy K. Votteler

FIRE: Forum for International Research in Education

This study aimed at examining the pedagogical needs and challenges of children and young adults living in a refugee camp in France known as the Calais Jungle. Through the researchers’ observations and interviews with volunteer teachers and workers at the camp, insights into their perspectives shed light on the pedagogical needs of refugees. Also, utilizing Paulo Freire’s philosophical stance, this study provides a contextual approach to the educational practices and ideological viewpoints represented within unregulated refugee camp settings.


The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske Jun 2017

The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske

Brian Gedlinske

Specific surface area is a property used by earth scientists to estimate the proportion of expandable clay minerals in soils. In this study, specific surface area method is shown to compare favorably with standard clay mineralogical techniques in determining gross differences in expandable clay mineral content in tills. The results of over 100 measurements on till samples from Iowa indicate undifferentiated pre-Illinoian tills from southern and southwestern Iowa have the highest specific surface area values of Iowa tills (ranging from nearly 100 to greater than 150 m2/g) and Wisconsinan Dows Formation tills have the lowest average specific surface area ...


Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore Jun 2017

Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore

Stephen J Dinsmore

In 1900, the range of the Great-tailed Grackle extended north of the Mexican border only into Texas. Since then, it has expanded its range greatly. It now nests in 14 states and has strayed to an additional eight states and three Canadian provinces. Much of this expansion has occurred since 1960. Great-tails often stray far from their normal range, especially in spring. Most of these strays are single individuals. In states where they have nested, breeding birds typically reach the state a few years after the first reports of the species. Great-tailed Grackles do well in a variety of human ...


The Bamboo Ceiling: A Study Of Barriers To Asian American Advancement, Emily Cheng Jan 2017

The Bamboo Ceiling: A Study Of Barriers To Asian American Advancement, Emily Cheng

Undergraduate Research Posters

The idea of cultural diversity in the workplace is a popular one, generating much discussion about the inclusion of and affirmative action toward minorities. However, these conversations rarely involve Asian Americans, who despite above-average levels of educational achievement, household income, and employment, find themselves underrepresented in and shut-out of upper-level management positions. In this project, I investigated the stereotype of East-Asian Americans as a model minority (created by non-Asians) to find out why East-Asian Americans are underrepresented in upper-level management in corporate workplaces, a phenomenon known as the “bamboo ceiling.” I explored a variety of scholarly sources that analyzed the ...


What Does Motivated Mean? Re-Presenting Learning, Technology, And Motivation In Middle Schools Via New Ethnographic Writing, Justin Olmanson Oct 2016

What Does Motivated Mean? Re-Presenting Learning, Technology, And Motivation In Middle Schools Via New Ethnographic Writing, Justin Olmanson

Middle Grades Review

This article offers a critique of the way middle schoolers are often positioned as generalizable objects that can be acted upon to produce measurable increases in motivation and learning. The critique invites a reconsideration and cultural analysis of some of the dominant discourses and perceptions of technology, young adolescence, and the study of motivation. The use of New Ethnographic Writing—a method that performs a cultural critique via extended scenes connects to the roles and status of motivation, technology, and educational research methods deployed within public schools. Coupled with weak theory, this approach offers a way to understand young adolescents ...


Using Science Communication And Informal Education To Become An Informational Portal To The Public, Karri D. Folks Apr 2016

Using Science Communication And Informal Education To Become An Informational Portal To The Public, Karri D. Folks

Iowa State University Anthropology Symposium

Effective communication with the public is a key component of research outreach. As graduate students, our curriculums usually require some form of public outreach. You are expected to demonstrate the broader impacts of your research through multi-generational education; however training for this type of communication is usually not provided. Reiman Gardens (Ames, IA) provides outreach development and training to Iowa State graduate students, scientists, engineers, researchers, and other science-based professionals through their Portal to the Public Science Communication Fellowship. The fellowship provides training on how to effectively communicate your research to diverse audiences and enhance science communication skills. Each fellow ...

Play As The Foundation Of Human Intelligence: The Illuminating Role Of Human Brain Evolution And Development And Implications For Education And Child Development., Aaron P. Blaisdell Sep 2015

Play As The Foundation Of Human Intelligence: The Illuminating Role Of Human Brain Evolution And Development And Implications For Education And Child Development., Aaron P. Blaisdell

Journal of Evolution and Health

Children love to play. Why do they find such a frivolous activity so pleasurable and desirable? Perhaps it is not frivolous, but instead is an adaptation designed to guide proper cognitive development in human children. To understand why, I marshal evidence from different fields to build a case for play as a central behavioral mechanism of human brain and cognitive development. I start with a discussion of human evolution, focusing on the evolution of human physiology, tool-use, the human brain, and life-history strategy, and development, and how these are all connected as an adaptive suite. The anthropological and developmental evidence ...


School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer Jan 2015

School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer

Honors Theses

School gardens have existed since the late nineteenth century and today are becoming increasingly popular in many parts of the world, including where I studied in Maine and Australia (AUS). Multiple organizations support school gardens in Maine, including the Maine School Garden Network, which has over 125 registered school gardens. In AUS, the Stephanie Alexander Kitchen Garden Foundation primarily supports the school garden movement and has over 800 registered school gardens. While many researchers have studied school gardens, few have compared two countries, focused on environmental sustainability, or investigated Maine in particular. This thesis combines information from literature reviews, and ...

The Animal Research Controversy: Protest, Process & Public Policy, Andrew N. Rowan, Franklin M. Loew, Joan C. Weer Sep 2014

The Animal Research Controversy: Protest, Process & Public Policy, Andrew N. Rowan, Franklin M. Loew, Joan C. Weer

Andrew N. Rowan, D.Phil.

The controversy today regarding the use of animals in research appears on the surface to be a strongly polarized struggle between the scientific community and the animal protection movement. However, there is a wide range of opinions and philosophies on both sides. Mistrust between the factions has blossomed while communication has withered. Through the 1960s, 1970s and early 1980s, the animal movement grew in numbers and financial resources, and developed much greater public recognition and political clout. The research community paid relatively little attention to the animal movement for much of this period but, alarmed by several public relations coups ...

An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez Jul 2013

An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez

Idaykis Rodriguez

Expertise in physics has been traditionally studied in cognitive science, where physics expertise is understood through the difference between novice and expert problem solving skills. The cognitive perspective of physics experts only create a partial model of physics expertise and does not take into account the development of physics experts in the natural context of research. This dissertation takes a social and cultural perspective of learning through apprenticeship to model the development of physics expertise of physics graduate students in a research group. I use a qualitative methodological approach of an ethnographic case study to observe and video record the ...

Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal Jan 2012

Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal

Journal of the Iowa Academy of Science: JIAS

A carbon index (Cl) is one of many soil quality indicators that depends on organic carbon concentration. One of the values of a soil carbon index is in determining the impact of agriculture practices (i.e., tillage, crop rotation, N management, etc.) on soil organic matter status of mineral soils. Interactions of climate, parent material, topography, time, and organisms including human activities influence soil organic carbon (SOC). This study developed a soil carbon index for mineral soil map units in Iowa using data collected by the Iowa Cooperative Soil Survey Laboratory and the USDA Soil Survey Laboratory for over 2 ...


Evidence From Detrital Zircon Ages For Middle Pennsylvanian Uplift And Drainage In The Source Area Of The Chariton Conglomerate And Marmaton Group Sandstones, Southern Iowa And Northern Missouri, Scott Mcfadden, Steven H. Emerman, Jane Pedrick Dawson, Kevin A. Rey, Tracy Kemp Anderson Jan 2012

Evidence From Detrital Zircon Ages For Middle Pennsylvanian Uplift And Drainage In The Source Area Of The Chariton Conglomerate And Marmaton Group Sandstones, Southern Iowa And Northern Missouri, Scott Mcfadden, Steven H. Emerman, Jane Pedrick Dawson, Kevin A. Rey, Tracy Kemp Anderson

Journal of the Iowa Academy of Science: JIAS

The Chariton Conglomerate is a quartz/limestone conglomerate of Middle Pennsylvanian age sparsely exposed in southern Iowa and northern Missouri. In Iowa it is characterized by quartz granules and rounded crinoid columnals. The objective of this study was to use detrital zircon ages to determine the provenance of the Chariton Conglomerate and possibly associated Marmaton Group sandstone beds. Detrital zircon ages were obtained for five conglomerate and two sandstone beds of the Chariton Conglomerate in Iowa, three conglomerate beds of the Chariton Conglomerate in Missouri, and two sandstone beds of the Marmaton Group in Iowa. According to the Kolmogorov-Smirnoff Test ...


Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald Jan 2012

Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald

Journal of the Iowa Academy of Science: JIAS

Harlan's ground sloth, Paramylodon harlani, is documented for the first time from Iowa. The record is based on a fifth metacarpal recovered from a gravel bar within West Tarkio Creek, Page County. While the specimen was not found in situ, and could not be radiocarbon dated, the local geology suggests that it was probably derived from sediments that post-date Peorian loess deposition and is late Wisconsinan in age. This specimen extends the range of Paramylodon 350 km ro the northeast of the closest previously known locality. Its size is slightly larger than average for other late Pleisrocene (Rancholabrean) individuals ...


Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch Jan 2012

Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch

Journal of the Iowa Academy of Science: JIAS

Bloodroot (Sanguinaria canadensis L., Papaveraceae) is a plant rich in benzophenanchridine (isoquinoline) alkaloids such as sanguinarine and chelerychrine. Both isolated alkaloids and whole-tissue rhizome extracts have demonstrated in vitro anticarcinogenic (antiproliferacive) activity in limited immortalized cell culture models, but the relative contribution of various alkaloid constituents to whole-tissue extract activity, and whether or not various alkaloids may act synergistically, has not been investigated. We challenged four immortalized cell lines (Jurkat, K562, Ramos, U937) with various doses of chelerythrine, sanguinarine, and berberine (a structurally and functionally similar alkaloid absent from bloodroot), alone and in all possible combinations, and measured proliferation rates ...
