Hooked On Peers’ Drawings: Learning Through The Visual Wildfire, Nina Scott Frisch

Learn X Design Conference Series

Children’s drawing activity has been theorized as traces of cognitive and biological development, with cultural variations as minor sources of visual and traceable influence. Even though present, less research has been done on documenting the social aspect of drawing; seeing drawing as visual communication between children. This aspect of drawing development, or learning, is visually traceable, but is still often neglected because children´s drawings can be seen in light of a discourse emphasizing the individual solitude and expression of the professional artist. Collection of drawings, observations and interviews took place in one elementary school art room for one academic year …

Parts Of The Whole: The Educational Sieve, Dorothy Wallace

Numeracy

This essay argues that the structure of course prerequisites affects retention of students in a course of study. The same argument suggests that the structure of degree requirements, including quantitative reasoning courses, affects retention in college. In particular, the same set of courses required in a rigid sequence will cause more students to exit the program early than if the same courses were offered in a flexible order.

Does Completion Of Quantitative Courses Predict Better Quantitative Reasoning-In-Writing Proficiency?, Nathan D. Grawe

Numeracy

Using data from Carleton College, this study explores the connection between students’ completion of a range of quantitative courses and the quality of their quantitative reasoning in writing (QRW) as exhibited in courses throughout the undergraduate curriculum during the first two years of college. Because the assessment takes place in the context of a campus-wide initiative which has improved QRW on the whole, the study identifies course-taking patterns which predict stronger than average improvement. Results suggest QRW is not exceptionally improved by taking courses in statistics, principles of economics, or in the social sciences more broadly. QRW performance is, on …

Making College Count: An Examination Of Quantitative Reasoning Activities In Higher Education, Louis M. Rocconi, Amber D. Lambert, Alexander C. Mccormick, Shimon A. Sarraf

Numeracy

Findings from national studies along with more frequent calls from those who employ college graduates suggest an urgent need for colleges and universities to increase opportunities for students to develop quantitative reasoning (QR) skills. To address this issue, the current study examines the relationship between the frequency of QR activities during college and student and institutional characteristics, as well as whether students at institutions with an emphasis on QR (at least one QR course requirement for all students) report more QR activity. Results show that gender, race-ethnicity, major, full-time status, first-generation status, age, institutional enrollment size, and institutional control are …

Financial Literacy And Quantitative Reasoning In The High School And College Classroom, Annamaria Lusardi, Dorothy Wallace

Numeracy

This overview frames the eight articles devoted to financial literacy in this issue of Numeracy. The survey questions used to assess financial literacy in the United States, Romania, France, Switzerland, Australia, and elsewhere include mathematics that is routinely covered in mathematics and quantitative reasoning courses. Financial literacy, wherever it is received, appears to benefit people throughout their lives. The close tie between quantitative and financial literacy may be exploited to introduce more of both into the high school and undergraduate curriculum.

Global Exponential Stability For A Class Of Impulsive Bam Neural Networks With Distributed Delays, I. M. Stamova, G. Tr. Stamov, J. O. Alzabut

Applied Mathematics & Information Sciences

In this paper, the exponential stability is investigated for a class of BAM neural networks with distributed delays and nonlinear impulsive operators. By using Lyapunov functions and applying the Razumikhin technique, delay–independent sufficient conditions ensuring the global exponential stability of equilibrium points are derived. These results can easily be utilized to design and verify globally stable networks. An illustrative example is given to demonstrate the effectiveness of the obtained results.

Storage Technique Preserves Citrus, Kills Pathogens, Gayle Volk, Jan Suszkiw

Agricultural Research Magazine

Americans consume about 84 pounds of fresh and processed citrus per person each year, with oranges topping the list at 61 pounds annually. The availability of these favored fruits in grocery stores, fresh markets, and other consumer outlets is a testament to growers’ success in managing the ever-present threat of pests and diseases to the nation’s $3.4 billion citrus crop (2011-12), most of which is produced in Florida and California.

A major threat is citrus greening disease, also known as “Huanglongbing.” First detected in Florida in August 2005, citrus greening today is the target of a multifaceted effort by federal, …

Fungi Can Be Friends Or Foes, Amy Rossman, Jo Anne Crouch, Shannon Dominick, Sharon Durham

Agricultural Research Magazine

Fungi are a large and diverse group of organisms. Some fungi, like mushrooms, are edible and considered crops. Others, however, can cause serious diseases of crop and forest plants, and those diseases can have negative effects on local and international economies as well as on the supply of food and other materials that agriculture provides.

The Agricultural Research Service maintains a unique resource—the U.S. National Fungus Collections—for helpful and detailed information about fungi. Accurate knowledge of fungi is critical for controlling the diseases they cause.

Gastrointestinal Helminths Of Two Species Of Mouse Opossums (Marmosa Demerarae And Marmosa Murina) From French Guiana, Beth Byles, Francois Catzeflis, R Philip Scheibel, Agustin Jimenez-Ruiz

Publications

The woolly mouse opossum Marmosa demerarae and the murine opossum, Marmosa murina, occur in sympatry across most of their range; however, they are not syntopic in that M. demerarae is more abundant in the canopy of primary and secondary forest, while M. murina is scansorial and appears to be more abundant in lower forest strata. We herein present a survey and comparison of the helminths occurring in these 2 species in French Guiana based on examinations of 18 individuals of M. murina and 21 individuals of M. demerarae. At the level of the component community, species richness was …

The Transcriptomics To Proteomics Of Hair Cell Regeneration: Looking For A Hair Cell In A Haystack, Gopinath Rajadinakaran

UCHC Articles - Research

Mature mammals exhibit very limited capacity for regeneration of auditory hair cells, while all non-mammalian vertebrates examined can regenerate them. In an effort to find therapeutic targets for deafness and balance disorders, scientists have examined gene expression patterns in auditory tissues under different developmental and experimental conditions. Microarray technology has allowed the large-scale study of gene expression profiles (transcriptomics) at whole-genome levels, but since mRNA expression does not necessarily correlate with protein expression, other methods, such as microRNA analysis and proteomics, are needed to better understand the process of hair cell regeneration. These technologies and some of the results of …

And-Not Logic Framework For Steady State Analysis Of Boolean Network Models, Alan Veliz-Cuba, Kristina Buschur, Rose Hamershock, Ariel Kniss, Esther Wolff, Reinhard Laubenbacher

Applied Mathematics & Information Sciences

In this paper we propose the class of AND-NOT networks for modeling biological systems and show that it provides several advantages. Some of the advantages include: Any finite dynamical system can be written as an AND-NOT network with similar dynamical properties. There is a one-to-one correspondence between AND-NOT networks, their wiring diagrams, and their dynamics. Results about AND-NOT networks can be stated at the wiring diagram level without losing any information. Results about AND-NOT networks are applicable to any Boolean network. We apply our results to a Boolean model of Th-cell differentiation.

Simulation Of Join Cardinalities In Random Databases Using Poisson Stochastic Processes, Letiția Velcescu

Applied Mathematics & Information Sciences

In this paper, using Poisson stochastic processes, we introduce an approach to the problem of the approximate join operation in random databases. It is shown that the cardinalities of the result sets obtained from an approximate join operation follow this type of stochastic process. Initially, we treat the case of the approximate join between two random tables, which is accomplished using a homogeneous bidimensional Poisson process. Further, we extend the obtained result to the case of the multiple join. This generalization is made through a multidimensional Poisson process. As a consequence, the algorithms that simulate these processes can also simulate …

A Parameter-Uniform Method For Two Parameters Singularly Perturbed Boundary Value Problems Via Asymptotic Expansion, D. Kumar, A. S. Yadaw, M. K. Kadalbajoo

Applied Mathematics & Information Sciences

An approximate method for two parameters singularly perturbed boundary value problems having boundary layers at both end points is given. The method is motivated by the asymptotic behavior of the solution. In the outer region the solution of the problem is approximated by the zeroth order asymptotic expansion while in the inner region the solution of the problem is obtained by using Bspline collocation method. The method is iterated on the transition point of the boundary layer region. To demonstrate the applicability of the method two test examples are considered.

The Association Between A Medical History Of Depression And Gestational Diabetes In A Large Multi-Ethnic Cohort In The United States, Katherine Bowers, S. Katherine Laughon, Sungduk Kim, Sunni L. Mumford, Jennifer Brite, Michele Kiely, Cuilin Zhang

Publications and Research

Background: Both major depression and gestational diabetes mellitus (GDM) are prevalent among women of reproductive age. Our objective was to determine whether a medical history of depression is related to subsequent development of GDM.

Methods: The Consortium on Safe Labor was a US retrospective cohort study of 228 562 births between 2002 and 2008. Exclusion criteria for the present analysis included multiple gestation pregnancies (n = 5059), pre-existing diabetes (n = 12 771), deliveries(n = 395), site GDM prevalence (

Results: The final analytic population included 121 260 women contributing 128 295 pregnancies, of which 5606 were affected by GDM. …

Approaches To Mental Illness In Madagascar: A Case For Reconciling Reason With Faith, Raisa Tikhtman

Independent Study Project (ISP) Collection

This paper expounds the shortcomings of the mental health provisions inherent in the current primary health care system in Madagascar in light of its limited accessibility to the Malagasy. Integrating traditional medicine with allopathic psychiatric care is proposed, with attention to prevailing Malagasy beliefs in spiritual possession as the basis for mental illness, in order to accommodate the discrepant worldviews espoused by physicians and their Malagasy patients that inhibit the efficacy of public mental health care. Through an integrated system based on the model piloted at the Clinique de Manongarivo in northwestern Madagascar, the financial, physical, and epistemological barriers that …

Integrated Health Care Systems: A Holistic Approach To Medicine, Tatiana Kaehler

Independent Study Project (ISP) Collection

This paper examines how the strengths of both allopathic and traditional medical systems are harnessed in integrated health care systems – a system which “consciously targets and harnesses people’s links with biodiversity for health care reasons” (Quansah, personal communication, July 1, 2013). It uses examples of integrated health care in Madagascar to prove that integrated health care systems offers health care in an affordable and accessible manner, while also promoting cultural sustainability and conservation of biodiversity. By recognizing and establishing integrated health care systems throughout the world, global health disparities can be addressed and various health goals can be accomplished.

Ecosystem Consequences Of Tree Monodominance For Nitrogen Cycling In Lowland Tropical Forest, E. N. Jack Brookshire, Steven A. Thomas

School of Natural Resources: Faculty Publications

Understanding how plant functional traits shape nutrient limitation and cycling on land is a major challenge in ecology. This is especially true for lowland forest ecosystems of the tropics which can be taxonomically and functionally diverse and rich in bioavailable nitrogen (N). In many tropical regions, however, diverse forests occur side-by-side with monodominant forest (one species >60% of canopy); the long-term biogeochemical consequences of tree monodominance are unclear. Particularly uncertain is whether the monodominant plant-soil system modifies nutrient balance at the ecosystem level. Here, we use chemical and stable isotope techniques to examine N cycling in old-growth Mora excelsa and …

Seasonal Fires, Bison Grazing, And The Tallgrass Prairie Forb Arnoglossum Plantagineum Raf., Stephen L. Winter, Karen R. Hickman, Carla L. Goad, Samuel D. Fuhlendorf, Mark S. Gregory

School of Natural Resources: Faculty Publications

Fire and grazing can interact to affect the structure and composition of vegetation communities in a manner that may differ from the effects of fire or grazing that occurs in isolation of the other. In order to better understand the effects of a fire-grazing interaction at the level of an individual plant species, we studied the response of a perennial tallgrass prairie forb, Arnoglossum plantagineum Raf., to the interaction of spring and summer fires with grazing by bison (Bison bison L.). During one field season (2006), we collected data in areas that had been treated with summer fires while …

Poverty, Wealth, And How Traditional Medicine Would Benefit The United States, Becky Darin Goldberg

Independent Study Project (ISP) Collection

This paper seeks to discover and address the various reasons as to how traditional medicine, “the sum total of knowledge, skills and practices based on the theories, beliefs and experiences indigenous to different cultures that are used to maintain health, as well as to prevent, diagnose, improve or treat physical and mental illnesses” (WHO 2013), would benefit the U.S. Within the United States, health disparities from race and geographic location are worsening, and traditional medicine could be a viable way of reversing this. Madagascar and the U.S. face similar issues within allopathic medicine such as distance to a doctor and …

Role Of Environment And Sex Differences In The Development Of Autoimmune Diseases: A Roundtable Meeting Project, Monica P. Mallampalli, Erika Davies, Debra Wood, Hillary Robinson, Federica Polato, Christine L. Carter

Prevention and Community Health Faculty Publications

Autoimmune diseases (ADs) impose substantial health and financial burdens in the United States and in many parts of the world. Women are disproportionately affected by many of these disorders, which often contribute to lifelong disabilities. While the number of patients with some ADs appears to be rising, the complexities of conducting epidemiological studies prevent a thorough understanding of the prevalence and incidence of these various conditions. Research on environmental influences of these illnesses is limited, although they are generally hypothesized to result from the interaction of environmental agents in genetically susceptible individuals. Further, there is little known regarding the role …
