The Normative Nature Of Risk Assessment: Features And Possibilities, Carl F. Cranor Mar 1997

The Normative Nature Of Risk Assessment: Features And Possibilities, Carl F. Cranor

RISK: Health, Safety & Environment (1990-2002)

Dr. Cranor argues that appreciating risk assessment to be permeated with normative presuppositions, in contrast with being primarily objective, opens up unforeseen possibilities for risk management.

Hot-Packaging Reduces Lipid Oxidation And Improves Sensory Characteristics Of Cooked Turkey Meat, Maiko Ishikawa, Dong U. Ahn Jan 1997

Hot-Packaging Reduces Lipid Oxidation And Improves Sensory Characteristics Of Cooked Turkey Meat, Maiko Ishikawa, Dong U. Ahn

Journal of the Iowa Academy of Science: JIAS

The effects of two vacuum packaging methods (hot and cold vacuum packaging) on the storage stability and sensory characteristics of cooked meat were compared. Ground turkey breast and leg meat patties were cooked, vacuum packaged appropriately, and stored up to 22 days. Lipid oxidation was measured by the thiobarbituric acid (TBA) test. In addition, Total aerobic count and sensory evaluation (flavor, juiciness, tenderness, overall acceptability) were conducted. There was no significant difference in aerobic plate count by packaging methods; however, panelist rating revealed that hot-packaged turkey leg meat had higher juiciness and overall acceptability scores than cold-packaged ones. Although TBARS ...

Nesting Status Of The Cooper's Hawk In Iowa: 1988-1996, David. J. Conrads Jan 1997

Nesting Status Of The Cooper's Hawk In Iowa: 1988-1996, David. J. Conrads

Journal of the Iowa Academy of Science: JIAS

The Cooper's Hawk was once considered a common nesting species in Iowa. Organochlorine pesticides and their residues, along with habitat loss contributed to its decline throughout the Midwest after the 1940's. This species was classified as endangered in Iowa in 1984, but recent trends in nests found indicate that the population of these hawks has increased. Since April 1988, 53 nests have been discovered in Iowa. Due to the apparent population growth, this species was removed from Iowa's endangered species list in 1994.

Fungal Colonization Of Alfalfa Stubble Following Harvest, J. K. O'Mara, G. P. Munkvold Jan 1997

Fungal Colonization Of Alfalfa Stubble Following Harvest, J. K. O'Mara, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Two-year-old stands of alfalfa cultivars Saranac and Vernal, planted in Central Iowa, were sampled 0, 15, and 30 days after the first harvest in 1995 to identify fungi colonizing the stubble left after harvest and evaluate the role of harvest-induced wounds as infection sites for potential crown-rotting fungi. Analysis of variance was conducted to determine if sampling date and cultivar significantly affected incidence of the fungi. All stems were infected with at least one fungal species at every sampling dare. The fungal genera most frequently isolated were Alternaria, Colletotrichum, Fusarium, Phoma, and Rhizoctonia. Fusarium acuminatum was the most frequently isolated ...


Distribution And Abundance Of Prairie Plant Species In The Loess Hills, Thomas R. Rosburg Jan 1997

Distribution And Abundance Of Prairie Plant Species In The Loess Hills, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

The species composition of grassland and ecotonal communities throughout the Loess Hills was studies between 1990 and 1993. Information pertaining to the latitudinal distribution of species in the Loess Hills, the abundance of species among community types (i.e., habitats), species persistence under woody encroachment, species associations, and resource partitioning among species is provided for the majority of grassland species occurring in the Loess Hills. The most abundant species on extant prairie in the Loess Hills include Bouteloua curtipendula (side-oats grama), Schizachyrium scoparium (little bluestem), Andropogon gerardii (big bluestem), Cornus drummondii (rough-leaved dogwood), Aster ericoides (heath aster), Carex heliophila (sun-loving ...


A Search For Average, Extremes, And Runs Of Unusual Weather In Iowa, R. E. Carlson, D. P. Todey Jan 1997

A Search For Average, Extremes, And Runs Of Unusual Weather In Iowa, R. E. Carlson, D. P. Todey

Journal of the Iowa Academy of Science: JIAS

Temperature and precipitation during the past decade have exhibited wide variation throughout Iowa. Is this unusual? An attempt was made to answer this question by computing various statistical parameters that characterize variation in Iowa's long term climatic record. Absolute deviations were used to identify the most and least variable months and years since 1900. Overall, 1936 with a very cold winter and very warm summer was the least normal year. Runs of daily weather showed that heat and cold stress could often persist for more than 1 month. Runs of dry days were much longer than runs of wet ...

Iowa's State Parks: A Various Language, Rebecca Conard Jan 1997

Iowa's State Parks: A Various Language, Rebecca Conard

Journal of the Iowa Academy of Science: JIAS

Iowa's state park system is distinctive because academically based natural scientists were instrumental in drafting the 1917 State Park Law, in shaping the initial policies, and in establishing the first parks. The mandate of the 1917 law was broad, but its original intent was to preserve and conserve natural resources; providing recreational enjoyment was secondary. Between 1920 and mid-century the founding vision was recast time and again by compromises that sprang from economic necessity, competing interests, and changing societal values. The ideal of resource protection has remained a guiding principle, however, in large part because strong personalities provided continuity ...


Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar Jan 1997

Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar

Journal of the Iowa Academy of Science: JIAS

Approximately 3% of Iowa's forests are contained in state parks and preserves. In addition to aesthetics and recreation, these protected forests provide a vital service in the unique opportunities they provide for forest research. As intact ecosystems where natural ecological processes dominate, they provide standards by which we measure the effects of livestock pasturing, methods of timber harvest, and other manipulations of managed forests. A number of current studies and public programs emphasize the importance of natural diversity in forests. They rely on state parks and preserves to provide a measure of potential diversity for a given region of ...


Research Note: Records Of Thirteen Ground Beetles (Coleoptera: Carabidae) New To Iowa, Foster Forbes Purrington, Kirk Jon Larsen Jan 1997

Research Note: Records Of Thirteen Ground Beetles (Coleoptera: Carabidae) New To Iowa, Foster Forbes Purrington, Kirk Jon Larsen

Journal of the Iowa Academy of Science: JIAS

A long-term ecological research initiative in northeast Iowa tallgrass prairies to evaluate the effects of prescribed burning on prairie insects was begun in 1993. During the course of this work we discovered 13 ground beetle species (Coleoptera: Carabidae) (Table 1) not previously reported from Iowa (Bousquet and Larochelle 1993).

Richard W. Pohl: Distinguished Botanist, Marjorie Conley Pohl

Journal of the Iowa Academy of Science: JIAS

In her biographical portrait of Dr. Richard W. Pohl, Mrs. Pohl provides an engaging personal perspective of her late husband, his development as a botanist, his career, and his family life. We gain a sense of Dr. Pohl as a dedicated scientist as well as a humanist. Although Dr. Pohl possessed an abiding curiosity regarding all things natural, he is best known and remembered for his focus on grasses. As Mrs. Pohl documents, this interest in grasses began in the late 1930's and continued throughout his life-ultimately he was regarded as an authority on grass taxonomy both nationally and ...
