Book Review - Birds In Iowa, Peter Wickham

Journal of the Iowa Academy of Science: JIAS

Here is a book that those who are interested in birds and their distribution in Iowa will absolutely have to possess. This volume is the successor to the book Iowa Birds, which was written by the above authors together with three others and published in 1984. It brings our understanding to the number of species of birds and their relative abundance in Iowa up-to-date. Although only twelve years elapsed between the publication of the previous volume and this one, the activity of those interested in identifying birds increased enormously during those years. In addition, their ability to identify and find …

A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis

Journal of the Iowa Academy of Science: JIAS

A survey of Iowa's floristic literature and herbarium resources indicates that while there is not uniform coverage of plant groups and regions, a great deal is known about the Iowa flora. Taxonomic and floristic studies are ongoing, despite evidence of a decreased number of researchers with expertise and interest in Iowa's flora and changing emphases in academic research. Current knowledge is sufficient for the production of an Iowa Flora, and an Iowa Flora committee to initiate this project is proposed.

Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

The status of Iowa's biodiversity was first summarized at a 1980 Iowa Academy of Science (IAS) symposium that was published in The Proceedings of the Iowa Academy of Science (Vol. 88, No. 1) in 1981. The 1980 symposium was updated in a recent IAS symposium, and the proceedings from this symposium are published, for the most part, in volume 105 of this journal. Most of the authors noted some positive trends, but, overall, species declines and habitat destruction remained a concern.

Safety Issues And Iowa Science Teachers, Jack A. Gerlovich, Ed Wilson, Rahul Parsa

Journal of the Iowa Academy of Science: JIAS

The National Science Education Standards are providing an excellent blue print for improving science teaching for all students. However, the Standards are placing serious demands on teachers attempts to make science activities inquiry-based, real-life, open-ended, and directly applicable to today's students. This situation is further aggravated when teachers do not know essential science safety information from both federal and state governing agencies, as well as professional organizations. With proper training and tools, however, this problem can be positively addressed.

A Feminist Approach To Social Scientific Evidence: Foundations, Andrew E. Taslitz

Michigan Journal of Gender & Law

This Article addresses several aspects of a feminist approach to social scientific evidence, specifically, the interpretive nature of mental states, the feminist attitude toward juries, and the political nature of evidence law.

Upstream Patents = Downstream Bottlenecks, Michael A. Heller, Rebecca S. Eisenberg

Law Quadrangle (formerly Law Quad Notes)

The following text is excerpted from "Can Patents Deter Innovation? The Anticommons in Biomedical Research" and is reprinted with permission from 280 Science 698-701 (May 1998). © 1998 American Association for the Advancement of Science.

Thirty years ago in Science, Garrett Hardin introduced the metaphor "tragedy of the commons" to help explain overpopulation, air pollution, and species extinction. People often overuse resources they own in common because they have no incentive to conserve. Today, Hardin's metaphor is central to debates in economics, law, and science and powerful justification for privatizing commons property. While the metaphor highlights the cost of overuse …

Intraspecific Heterochrony And Life History Evolution: Decoupling Somatic And Sexual Development In A Facultatively Paedomorphic Salamander, Travis J. Ryan, Raymond D. Semlitsch

Scholarship and Professional Work - LAS

Morphological features such as size and shape are the most common focus in studies of heterochronic change. Frequently, these easily observed and measured features are treated as a major target of selection, potentially ignoring traits more closely related to fitness. We question the primacy of morphological data in studies of heterochrony, and instead suggest that principal sources of fitness, such as life history characteristics, are not only the chief targets of selection, but changes in them may necessitate changes in other (subordinate) elements of the organism. We use an experimental approach to investigate the timing of metamorphosis and maturation in …

Reproductive Ecology Of Canada Mayflower (Maianthemum Canadense Desf), Michael Todd Ganger

Doctoral Dissertations

Canada mayflower (Maianthemum canadense var. canadense Desf.), a rhizomatous perennial herb, was the subject of field experiments investigating the role of several factors on the sexual reproduction of ramets. Mayflower ramets may be either flowering (with 2-3 leaves and a terminal inflorescence consisting of 4-35 perfect flowers) or vegetative (1 leaf).

Pollen addition increased the number of seeds matured by ramets in three out of four years in which pollen level was experimentally manipulated. The lack of compatible pollen is thought to be a major factor limiting seed maturation by ramets.

The act of severing the rhizomes, such that ramets …

Transactional Bond In The Novels Of Charles Brockden Brown, Gretchen Elspeth Digeronimo

Doctoral Dissertations

The six novels and various other fiction pieces Charles Brockden Brown wrote between 1799 and 1801 coherently demonstrate the operation and effect of literary and artistic representation in early Republican America.

In original close readings of Arthur Mervyn, Edgar Huntly, Ormond, and several other works, this dissertation identifies transactional bond and describes how Brown charted the establishment of the public and private individual self through transactional bond in three specific arenas: relationships between the developing self and written, visual, or reported representation; relationships between master/mentors and apprentices; relationships among women.

Bonds that begin, operate, and dissolve between male characters are …

Alternative Removal Methodologies For Environmental Waters, Shannon Patrick Hogan

Doctoral Dissertations

The Environmental Protection Agency (EPA) continues to establish criteria for the reduction of pathogens in environmental waters used for drinking water. The EPA also states criteria on the amount of chlorine by-products allowed in drinking water. Alternative removal methods that are used in conjunction with chlorine are needed to assure safe drinking water.

The Surface Water Treatment Rule (SWTR) states that a 99.99% reduction of viruses and a 99.9% reduction in Giardia lamblia cysts needs to be achieved by a treatment facility that uses surface water for the production of drinking water. The SWTR also states Maximum Contaminant Levels (MCL) …

In Pursuit Of "A Good Healthy Chat": The Roles Of Organization And Rapport-Building In Effective Middle School Literacy Instruction, Douglas Kingsley Kaufman

Doctoral Dissertations

In this study I explore what classroom conditions a master eighth-grade language arts teacher created in order to become a more effective listener. I defined effective listening as a deep receptivity that leads the listener to create responses that satisfy the other's needs. Responses must help students move their ideas and work progressively forward. Conditions that promote effective listening, then, serve two purposes: they (1) enhance teacher receptivity and (2) help students better articulate their interests, knowledge, and needs.

During the 1996-1997 school year I conducted a qualitative study that drew heavily upon ethnographic methodologies. As a participant-observer I took …

Factors That Influence The Decision Regarding Hormone Replacement Therapy In Postmenopausal Women, Ruth A Rogers Reilly

Doctoral Dissertations

Cardiovascular disease is the leading cause of death in women in the United States today. Prior to menopause women have lower rates of heart disease than men; however, after menopause a woman's risk for heart disease rises dramatically. This is thought to be due the ovaries' decreased production of estradiol, but the mechanisms for this effect have not been fully elucidated. The need exists to investigate the impact of healthy lifestyles on attenuating the risk of cardiovascular disease in women as they age.

The majority of research on hormone replacement therapy (HRT) has focused on the biomedical model suggesting that …

Reconceptualizing Early Childhood Preservice Teacher Education: A Pedagogy Of Collaborative Inquiry, Mary Jane Moran

Doctoral Dissertations

This study describes changes in thinking and practice among 24 early childhood preservice teachers as they move away from a reliance on traditional interpretations of child-centered curricula and developmentally appropriate practices toward one of collaborative inquiry. Participants enrolled in a 15 week undergraduate teaching methods course were assigned to teaching teams to implement collaborative projects with the same group of three to five year-old children.

Traditionally, early childhood teacher education has been influenced by developmental theory which emphasizes processes of children's learning. And yet, teachers typically learn to teach from a transmission orientation with perspectives provided by experts rather than …

Bioavailability Of Nutrients And Metals Following Land Application Of Organic Wastes, Jianqiang Zhao

Doctoral Dissertations

Field, greenhouse and laboratory studies were conducted to investigate the effects of soil-incorporated organic wastes on nitrogen release patterns, groundwater nitrate-nitrogen levels, nutrient/metal uptake, and plant yield.

Three field studies with corn (Zea mays L.) were conducted during 1993 to 1997 at three locations in New Hampshire using a randomized complete block design with three or four replications, two or three waste materials as main plots, and various application rates as subplots. Compared to dairy manure, Concord biosolids showed a slower release rate measured as soil NO$\sb3$-N concentrations in early season but higher post-harvest levels of soil NO$\sb3$-N.

Groundwater NO$\sb3$-N …

Issues Of Engendered Entitlement: Who Owns The Classroom? Who Owns Knowledge?, Dorothy Radius Kasik

Doctoral Dissertations

This dissertation examines the ways in which first year female college students have been prepared by educational systems in our culture to handle knowledge and the acquisition of knowledge during the first year of college experience. It is the contention of the author that women are not actively encouraged in our culture to take ownership of educational concepts in the same way as men. This happens for two reasons, first that because women's methods of interaction in the classroom might differ from men's those methods might not be perceived as acceptable or taken seriously; and second that a woman's discomfort …

Dynamics Of Dissolved Organic Carbon During Weathering And Soil Formation, Kimberly Linnea Mccracken

Doctoral Dissertations

Interactions between dissolved organic carbon (DOC) and mineral soils were examined in field and laboratory experiments. Specific emphasis was given to factors influencing DOC mobility and element release during mineral weathering and soil formation. Soil chemical and physical properties controlling equilibrium concentrations of DOC (DOC$\rm\sb{np})$ in coarse-textured forest soils were investigated using laboratory batch reactors and the initial mass isotherm approach. The influence of DOC concentration on release of metals and silica was investigated in four soil parent materials. One of four acid treatments (0.001 N HNO$\sb3$ and three concentrations of forest floor leachate) or distilled water were added to …

Attachment Of Listeria Monocytogenes To Murine And Human Phagocytic Cells, Srinivas Maganti

Doctoral Dissertations

Listeria monocytogenes is a facultative intracellular pathogen responsible for meningoencephalitis, septicemia, and abortion in susceptible and immunocompromised individuals. Subsequent to colonization and penetration of the gut epithelium, the organism attaches to resident macrophages and replicates intracellularly, thus evading the humoral immune system of the infected host. The mechanism surrounding the precise interactions between L. monocytogenes and macrophages employs bacterial ligands and macrophage receptors which are highly complex and not well understood. The focus of the present study was to investigate the attachment of the organism to murine and human macrophages under opsonin-dependent and opsonin-independent conditions to better understand the pathobiology …

Controls On Ch(4) Emissions From Boreal And Arctic Wetlands, Sadredin Cyrus Moosavi

Doctoral Dissertations

This thesis examines the environmental controls on the biogeochemical cycling of the radiatively active trace gas CH$\sb4$ within boreal and arctic wetlands. Net CH$\sb4$ flux along peatland hydrologic gradients were examined to determine the effects of temperature and water table on CH$\sb4$ emissions. The level of the water table acts as a switch between CH$\sb4$ production and oxidation with small water level changes producing large changes in flux balance. Soil temperature determined whether CH$\sb4$ production potential was realized within sufficiently moist environments. A selective inhibitor technique was developed for directly measuring CH$\sb4$ oxidation in wetland soils. CH$\sb4$ oxidation was found …

Turning To Earth: Paths To An Ecological Practice, Florence Marina Schauffler

Doctoral Dissertations

In highly developed countries like the United States, conventional approaches to environmental change emphasize systemic measures such as policies and regulations. Yet many intractable environmental problems appear to be rooted in the perspectives and practices of individual citizens. Efforts to restore 'outer ecology' may depend, therefore, on transforming 'inner ecology'--the constellation of spiritual and moral values that guide action. This dissertation examines the inner dimensions of ecological change, demonstrating how individuals redefine their relation to earth through a process of 'ecological conversion.'.

In assessing the dynamics of conversion, this work relies primarily on the testimony of six 20th-century American writers: …
