Aryl Ethers From Arenediazonium Tetrafluoroborate Salts: From Neat Reactions To Solvent-Mediated Effects, James A. Shriver, Daniel P. Flaherty, Cameron C. Herr

Journal of the Iowa Academy of Science: JIAS

A general procedure for the synthesis of various aryl ethers via the thermal decomposition of benzenediazonium tetrafluoroborate salts is described. Studies performed in neat alcohol at 60°C gave aryl ethers in yields ranging from 0-73%. Upon completion of a series of reactions, the effect of solvent was explored to expand the scope and relevance of this procedure. It was found that even solvents that are traditionally non-nucleophilic gave rise to products including bi-aryls and N-aryl acetamides. The utilization of an ionic liquid, l-butyl-4-methylpyridinium tetrafluoroborate, resulted in yields comparable to reactions performed in neat alcoholic solvents.

The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke

Journal of the Iowa Academy of Science: JIAS

The lower Missouri River has historically been viewed as a fauna! barrier for unionids due to high sediment load. However this survey of the lower (channelized) Missouri River documented the presence of 14 unionid species and the exotic Corbicula fluminea (Muller, 1774). Unionids are present in stable substrates sheltered from the effects of the river's strong currents. Analysis of early literature on the Missouri River suggests reports of an absence of unionids were not based upon thorough fieldwork, and the most commonly cited rationale for their reported absence, the high sediment load in the river, is not convincing. Pre-1938 unionid …

The Iowa Core Curriculum And Me: How My Teaching Of Mathematics Methods Will Change, Catherine M. Miller

Faculty Work

It is an exciting time to be a mathematics educator in Iowa! We are joining the other 49 states by having a set of state standards. In fact, Iowa is exceeding federal expectations by having a curriculum to inform the work of teachers and school administrators. Because of this, we enter an era of change in Iowa and, as we know, change is never easy. To succeed in implementing the Iowa Core Curriculum (ICC) in mathematics all teachers need to learn about it and have help in implementing its core ideas and content. This includes teachers who will begin their …

Meaningful Distributed Instruction— Developing Number Sense, Edward C. Rathmell

Faculty Work

What Is Number Sense?

The primary goal for elementary and middle school mathematics is to help students learn to use numbers meaningfully, reasonably and flexibly in everyday life. This means that students must develop a deep understanding of

-- numbers and operations,
-- when operations can appropriately be used to solve problems, and
-- judging the reasonableness of their solutions to problems.

They also need to develop attitudes so they

-- believe they can make sense of mathematics, and
-- habitually try to make sense of mathematics.

In other words, students need to develop number sense.

Understandings Needed for Number …

Conceptual Previews In Preparation For The Next Unit Of Instruction, Michele Carnahan, Bridgette Stevens

Faculty Work

Understanding meanings of operations and how they relate to one another is an important mathematical goal for students in fourth grade (National Council of Teachers of Mathematics, 2000). Using pictures, diagrams, or concrete materials to model multiplication helps students learn about factors and how their products represent various contexts. The foundation of understanding how operations of multiplication and division relate to one another deepens the understanding of the composition of numbers. Discussing different types of problems that can be solved using multiplication and division is important, along with the ability to decompose numbers. When students can work among these relationships …

Personal Epistemologies And The Learning Paradox In Teacher Education: A Neglected Dilemma, Elana Joram, Carmen Montecinos

Faculty Publications

In this chapter, we discuss the role that personal epistemologies play in teacher education, particularly with respect to the potential problems and roadblocks they may present. We suggest that epistemological beliefs govern the kind of knowledge that preservice teachers consider to be legitimate and worthwhile learning in their programs, regulate the ways in which they make choices among competing knowledge claims and justify their own choices. A body of research has examined epistemic cognition as a dimension of the cognitive growth that occurs during the college years (e.g., Baxter- Magolda, 2002; King & Kitchener, 2002; Perry, 1970), and recently, the …

Cedar Rapids Flood Of 2008: Manmade Or Statistical Anomaly?, Beth Kolsrud

Honors Program Theses

One of the main research questions for this thesis is what factors caused the flooding last summer and why was it so extreme? This is an important question to answer because it is vital to understand what causes a flood of this magnitude so communities can take steps to avoid or minimize damage that may result from floods in the future. The second question is what impact does this flood have on flood insurance? Flood insurance is one tool used to protect property owners from substantial loss due to flooding and plays a vital role in recovery after a flood, …

Managing Risk In Life Insurance With Your Genetic Information: The Issues, The Options, And The Speed Of Progress, Michelle Gogerty

Honors Program Theses

legislation is already in place to restrict the use of genetic information in the health insurance industry (Genetics and Public Policy Center 2008) and several states have similar laws restricting its use in the life insurance industry as well (National Conference of State legislatures 2008}. It is only a matter of time before national legislation applicable to life insurance is enacted on the matter and I expect it to come within the next five years. Unless both insurers and consumers actively protect their rights to privacy, equality, and profitability, the result of that legislation may be very harmful to one …

Spatial, Geologic, And Land Use Characteristics Of Sinkholes In A Karst Landscape: Waverly, Iowa, Adam Richard Campbell

Honors Program Theses

The city of Waverly and its surrounding area in the Waverly Quadrangle has the fortune of having a large supply of groundwater that is easily accessible. However, the karst landscape that comprises much of the quadrangle has made the groundwater supply vulnerable to degradation from point and non-point contamination. Thus, it is crucial to explore the properties of sinkholes in the region to determine their threat to groundwater. To determine this threat, it is necessary to examine the characteristics of where and under what circumstances sinkholes develop. The Waverly Quadrangle is located entirely within the Iowan Surface. The bedrock in …

Ambigrams: The Art And The Math, Callie Kronlage

Honors Program Theses

Because ambigrams are a relatively new concept, I found little mathematical research on them. Throughout this paper, I will address the role of ambigrams as a mathematical entity, an artistic outlet, and even an educational tool. Along with ways to use ambigrams, there are also descriptions of the nine different types of ambigrams, and a chart that can be used to create two of the most common types of ambigrams. Mathematically, ambigrams contain many symmetrical aspects, which are important to the study of Geometry. Within this, I have researched mathematical aspects of three of the ambigram types and found some …

Preliminary Development Of Quantitative Immunoassays For Mitochondrial Proteins, Adriann Hovey

Honors Program Theses

Mitochondria are medium-sized organelles in which most cellular metabolic reactions are carried out. In postmitotic cells that are aged or diseased, such as myocardial, skeletal, and brain cells, abnormally large mitochondria ("giant mitochondria") are often observed. Mitochondrial size and shape are controlled by mitochondrial fusion and fission and disruption of this process may lead to their abnormally large size (Nauratil, Terman, Arriaga, 2008). These giant mitochondria exhibit variations from normal metabolism and altered membrane potentials (Nauratil et al., 2008). An increased number of giant mitochondria may therefore disrupt cell function (Nauratil et al., 2008). This accumulation may result either from …

Resumes And Cover Letters: The Accuracy Of Extraversion Judgments Made From Resume And Cover Letter Biodata, Matthew Sean Christensen

Dissertations and Theses @ UNI

This following thesis study examined the accuracy of extraversion judgments accrued from resumes and cover letters. Within personnel selection, professionals often rely upon the applicant resume as an initial prescreening tool. Little empirical research, however, has explored whether reviewers use the resume and cover letter in a reliable fashion. Moreover, the current research base has not explored whether cover letters improve the accuracy of certain personality inferences made from resume biodata. Based upon the premises of Funder's (1995) Realistic Accuracy Model (RAM), the author posited that cover letters improve the accuracy of extraversion judgments made from resumes. The second intention …

Curriculum Development Project: Water Quality Unit, Keith Weber

Graduate Research Papers

As a cumulation of my studies and to satisfy the non-thesis option for my graduate program at the University of Northern Iowa (UNI), I designed this Water Quality Unit to be used for 9th and 10th grade students. It uses both learning cycles and a constructivist approach to satisfy Dubuque Community School District and Iowa Core Curriculum Standards. Each learning cycle applies the 3-E approach [Explore, Explain and Extend]. The unit contains seven separate learning cycles and ends with a final project in which students analyze the runoff from their school's watershed for various pollutants to determine what steps can …

A Working Conference On Students With Disabilities In Stem Coursework And Careers, Audrey C. Rule, Greg P. Stefanich, Charlotte W. Haselhuhn, Belinda Peiffer

Faculty Publications

Background: Few teachers and special education specialists are aware of the materials and resources available to support science; technology; engineering; and mathematics instruction for the scattered and isolated 3000 students with sensory and motor disabilities in Iowa's K-12 schools. Additionally; faculty at many community colleges and regent institutions are not aware of possible accommodations for their students with disabilities who have interests in pursuing STEM careers. Unfortunately; this often leads to discouragement and lack of success for students with motor or sensory disabilities. This conference brings together experts and conference attendees involved in instruction; support; or transitions for these students …

Teacher-Child Relationships In Early Childhood Classrooms, Michelle Tuttle

Graduate Research Papers

The purpose of this review was to evaluate the existing evidence of child and teacher relationships in early childhood settings on children's academic performance. Relationships were examined between parent and child, childcare provider and child, and teacher and child. Parent-child and teacher-child relationships are interrelated. The relationships interact with one another and influence the way a child develops. Children found with quality parent and teacher relationships were better able to concentrate, explore the environment, and ask adults for help. Research also found that quality activities in the classroom promoted strong teacher-child relationships. Two types of instruction, direct instructions and child-centered, …

Technology Integration: A Study On The Impact Of Increased Technology Access, Gina Kuker

Dissertations and Theses @ UNI

Colleges with teacher education programs have struggled to integrate technology into the curriculum. While access to technology has increased and support for technology usage is present, technology integration has not dramatically changed within the majority of classrooms (Cuban, 2001; Opperheimer, 1997; Stenson & Bagwell, 1999). Education faculty members should model effective technology integration within their classrooms in order for their preservice educators to see examples of how to incorporate technology into teaching and learning. Teachers tend to teach the way that they were taught (Judson & Swanda, 2001; Lortie, 1975). Without seeing how to integrate technology use across content areas, …

Dissertations and Theses @ UNI

The purpose of this study was to investigate the growth trajectory of college and/or university students in core competencies from entry to exit in the Camp Adventure™ Youth Services (CAYS) experience using the lens offered by Bok's framework. Specifically, students' growth patterns in core competencies were charted at three phases, namely, (1) baseline of their core competencies at entry level; (2) after receiving knowledge and practical training on the theory and implementation of CAYS' course but before its field experience; and (3) immediately after the CAYS' field experience. The core competencies included in the study were, according to Bok's framework, …

Development Of A Spatial Decision Support Tool For Watershed Critical Area Identification Of Soil Loss And Best Management Practices (Bmps) Evaluation, Luhua Cai

Dissertations and Theses @ UNI

Soil erosion has been identified as a major contributor to water quality degradation. Agriculture is historically known for accelerating soil erosion. In Iowa, with 88% of land in agriculture use, agricultural practices have became the dominant source of nonpoint source pollution and soil erosion is the leading water problem in Iowa. Controls of soil erosion are needed. Best Management Practices (BMPs) are recognized as the most efficient way to control non-point source pollution, and numerous BMPs have been developed for soil erosion control. Therefore, it is important to have a decision support tool that can identify the soil erosion problem …

The Effectiveness Of Colored Overlays On Reading Achievement And Attitudes Toward Reading For Students With Scotopic Sensitive Syndrome, Hanan Ali Bagabas

Dissertations and Theses @ UNI

This study investigated the effects on students identified with Scotopic Sensitivity Syndrome (SSS) or Irlen Syndrome (IS) when using colored overlays as an intervention (immediately and over time) to assess reading performance (rate, accuracy, and comprehension); to measure visual-motor integration; and to assess attitude toward reading. SSS/IS is a visual perceptual problem related to a collection of symptoms that affects an individual's performance when reading. Three participants, all males (one 3rd -grade student, one 4th -grade student, and one 5th -grade student), were identified as having SSS/IS and other learning disabilities.

The study involved five test instruments (Irlen Reading Perceptual …

Further Delineation Of The Role Of The Amygdala In Face Processing And Racial Categorization, Osman Afzal Chowdhry

Dissertations and Theses @ UNI

DNA exonerations in the legal system have increased steadily since 1989 from one or two per year to an average of 21 per year since 2001. A disquieting number of these exonerations originated from wrongful convictions following cross-racial identifications. Explaining the prevalence of erroneous cross-racial identifications centers on the Cross Race Effect (CRE), a phenomena whereby recognition for one's own race greatly outweighs recognition ability for other-race faces. Forty years of research in this area has produced a number of competing explanations. Recent neurological evidence has demonstrated separate neural regions for the processing of same-race and other-race faces as well …

The Relationship Between Academic Achievement And Physical Fitness In Adolescents, George William Centeio

Dissertations and Theses @ UNI

In today's schools, there is a major emphasis placed on academic proficiency particularly in the areas of reading, math, and science. Society is also seeing increases in the number of people who are obese and inactive. Some believe that increasing physical activity and/or improving physical fitness will result in better academic achievement of students in school. This study examined the relationship between academic achievement and physical fitness in adolescents. The participants included 200 ( 118 male, 82 female), high school students, at a rural high school located in the Midwestern region of the United States. Student's third trimester, end of …
