Beyond Dualism In The Life Sciences: Implications For A Feminist Critique Of Gender-Specific Medicine, Victoria Grace Jun 2007

Beyond Dualism In The Life Sciences: Implications For A Feminist Critique Of Gender-Specific Medicine, Victoria Grace

Journal of Interdisciplinary Feminist Thought

There are needed some alternative means of conceptualizing some of the central assumptions that support a dualist ontology in the life sciences. A reconceptualisation is crucial for an adequate understanding of the living body. Gender-specific medicine is important for women’s health, and it is making headway against internal conservatism and opposition. Men and women are different, what must be recognized and incorporated into health research, health care, and medical education. Sex hormones, featured as integral to the constitution of difference, are evidently influential in a multitude of sites of bodily function.

Relationship Web: Realizing The Memex Vision With The Help Of Semantic Web, Amit P. Sheth Jun 2007

Relationship Web: Realizing The Memex Vision With The Help Of Semantic Web, Amit P. Sheth

Kno.e.sis Publications

Relationship Web takes us from "which document" could have information I need to "what's in the resources" that gives me the insight and knowledge I need for decision making. Dr. Vannevar Bush outlined his vision for Memex in a 1945 Atlantic Monthly article [1]. Describing how the human brain navigates an information space in what he called trailblazing, Dr. Bush said, "It operates by association. With one item in its grasp, it snaps instantly to the next that is suggested by the association of thoughts, in accordance with some intricate web of trails carried by the cells of the brain." …

Determination Of Interphase Line Tension In Langmuir Films, Jacob R. Wintersmith '06, Lu Zou, Andrew J. Bernoff, James C. Alexander, J. Adin Mann Jr. Jun 2007

Determination Of Interphase Line Tension In Langmuir Films, Jacob R. Wintersmith '06, Lu Zou, Andrew J. Bernoff, James C. Alexander, J. Adin Mann Jr.

All HMC Faculty Publications and Research

A Langmuir film is a molecularly thin film on the surface of a fluid; we study the evolution of a Langmuir film with two coexisting fluid phases driven by an interphase line tension and damped by the viscous drag of the underlying subfluid. Experimentally, we study a 4′-8-alkyl[1,1′-biphenyl]-4-carbonitrile (8CB) Langmuir film via digitally imaged Brewster angle microscopy in a four-roll mill setup which applies a transient strain and images the response. When a compact domain is stretched by the imposed strain, it first assumes a bola shape with two tear-drop shaped reservoirs connected by a thin …

Bridging The Lis-Practitioner Gap: Some Frames For Research, Felix T. Chu Jun 2007

Bridging The Lis-Practitioner Gap: Some Frames For Research, Felix T. Chu

Library Philosophy and Practice (e-journal)

There is a divide between published research from library school (LIS) faculty and the use of these publications by practitioners in the field. This article suggests ways to bridge the gap between theory and practice. The suggestions are ways to frame the analyses of useful research areas that can help us improve the practice of librarianship. The first two, structural secrecy and improvisation, are operational in nature and deal with the day-to-day procedures. The third, naturalistic decision making, concerns making choices in the performance of duties. The fourth area, tacit knowledge, is the assumptions rooted in our knowledge of professional …

Temporal Changes In Nutrient Transport Following Land Application Of Manure, John E. Gilley, Eghball Bahman, D. B. Marx Jun 2007

Temporal Changes In Nutrient Transport Following Land Application Of Manure, John E. Gilley, Eghball Bahman, D. B. Marx

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Little information is currently available concerning temporal changes in nutrient transport following the addition of manure to cropland areas. This study was conducted to measure nutrient transport in runoff as affected by tillage and time following the application of beef cattle or swine manure to a site on which corn [Zea mays (L.)] was grown. Rainfall simulation tests were initiated 4, 32, 62, 123, and 354 days following land application. Three 30-min simulated rainfall events, separated by 24-hour intervals, were conducted at an intensity of approximately 70 mm hr-1. Dissolved phosphorus (DP), particulate phosphorus (PP), total phosphorus (TP), NO3-N, …

Trend Analysis Shows Decline Of An Endangered Thermophilic Springsnail (Pyrgulopsis Bruneauensis) In Southwestern Idaho, Cary D. Myler, Greg C. Mladenka, G. Wayne Minshall Jun 2007

Trend Analysis Shows Decline Of An Endangered Thermophilic Springsnail (Pyrgulopsis Bruneauensis) In Southwestern Idaho, Cary D. Myler, Greg C. Mladenka, G. Wayne Minshall

Western North American Naturalist

We analyzed population trend data during 1991–2004 for the Bruneau hot springsnail (Pyrgulopsis bruneauensis) from rangewide hot spring surveys completed along 4 km of Bruneau River. The objectives of this study were to analyze population trends and assess other measured parameters, such as water temperature, specific conductance, and groundwater decline, for changes that may influence population trends. We used simple linear regression to determine significant relationships between measured parameters. Total numbers of hot springs surveyed in the 4-km reach are declining at a rate of ~5 hot springs per year, and numbers of hot springs containing P. bruneauensis …

Salvage Logging And Replanting Reduce Understory Cover And Richness Compared To Unsalvaged-Unplanted Sites At Mount St. Helens, Washington, J. H. Titus, E. Householder Jun 2007

Salvage Logging And Replanting Reduce Understory Cover And Richness Compared To Unsalvaged-Unplanted Sites At Mount St. Helens, Washington, J. H. Titus, E. Householder

Western North American Naturalist

The 1980 eruption of Mount St. Helens killed trees in a broad 600-km2 swath north of the crater. Over most of the blast zone, dead trees were salvage logged and Abies procera was planted, except in areas within the Mount St. Helens National Volcanic Monument. We compared salvage-replanted sites and unsalvaged sites in 1 area of the blast zone where the sites were adjacent by using twenty-five 200-m2 plots for each treatment. Salvaged-replanted plots had significantly lower herb and shrub cover, richness, diversity, litter depth, downed woody debris, nitrate, and phosphate. Salvaged-replanted sites also had significantly more stumps, …

Breeding Biology And Flower Visitors Of The Rare White River Penstemon, Penstemon Scariosus Var. Albifluvis (Scrophulariaceae), Jennifer S. Lewinsohn, Vincent J. Tepedino Jun 2007

Breeding Biology And Flower Visitors Of The Rare White River Penstemon, Penstemon Scariosus Var. Albifluvis (Scrophulariaceae), Jennifer S. Lewinsohn, Vincent J. Tepedino

Western North American Naturalist

We studied the breeding system and flower visitors of White River penstemon, a rare endemic from the Uintah Basin of eastern Utah and western Colorado. Bagging treatments and hand-pollination treatments showed that Penstemon scariosus var. albifluvis has a mixed mating system: while some seeds and fruits are produced through selfpollination (both autogamy and geitonogamy), significantly more are produced when flowers are cross-pollinated. The primary flower visitors, and likely pollinators, were several species of native twig- and ground-nesting bees in the families Apidae, Halictidae, and Megachilidae. We found no differences in fruit or seed production between open-pollinated controls and hand-outcrossed flowers, …

Yellow Pine Chipmunks Cannot Climb Quaking Aspens: Implications For Avian Nest Site Selection, T. Will Richardson, Stephen B. Vander Wall Jun 2007

Yellow Pine Chipmunks Cannot Climb Quaking Aspens: Implications For Avian Nest Site Selection, T. Will Richardson, Stephen B. Vander Wall

Western North American Naturalist

Predation of eggs or nestlings is generally believed to be the most influential factor limiting passerine reproductive success. Thus, there should be strong selective pressures for birds to place their nests in sites that are inaccessible to predators or that are less likely to be discovered by them. We found and monitored 231 nests of 4 species of arboreal, cup-nesting birds: Western Wood-Pewee (Contopus sordidulus), Warbling Vireo (Vireo gilvus), American Robin (Turdus migratorius), and Yellow-rumped Warbler (Dendroica coronata). We determined strength of nest tree species selection by comparing nest trees and tree …

Food Web Structure, Energetics, And Importance Of Allochthonous Carbon In A Desert Cavernous Limnocrene: Devils Hole, Nevada, Kevin P. Wilson, Dean W. Blinn

Western North American Naturalist

We tested the hypothesis that allochthonous carbon is important in the diet of the endemic pupfish Cyprinodon diabolis over a 3-year period in Devils Hole, Nevada. Devils Hole is a cavernous limnocrene located in the Mojave Desert approximately 15 m below the land surface and receives direct solar radiation <7% of the total time during the year. The system is dominated by filamentous cyanobacteria in the summer and supports about 15 invertebrate species and the endemic pupfish C. diabolis. We examined food web structure and measured autochthonous carbon production and entry of allochthonous carbon with funnel traps. Stable isotopes were used to compare contributions of each carbon source. Allochthonous carbon contributed 2971 kj · yr−1 (60%) of the total available energy to the food web compared …

Runoff Nutrient Concentrations Following Manure Application As Affected By Crop Residue, John E. Gilley, Jeffrey Nicolaisen, Eghball Bahman, David B. Marx Jun 2007

Runoff Nutrient Concentrations Following Manure Application As Affected By Crop Residue, John E. Gilley, Jeffrey Nicolaisen, Eghball Bahman, David B. Marx

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Manure is applied to cropland areas managed under diverse conditions resulting in varying amounts of residue cover. The objective of this study was to measure the effects of crop residue on nutrient concentrations in runoff from areas where beef cattle or swine manure were recently applied but not incorporated. Plots 0.75 m wide by 2 m long were established at the study site. Existing residue materials were removed, and corn, soybean, or winter wheat residue was added at rates of 2, 4, or 8 Mg ha-1. Manure was applied at rates required to meet estimated annual nitrogen requirements for corn. …

Moldboard Plowing Following Compost Application Significantly Reduces Nutrient Transport, John E. Gilley, Bahman Eghball, David B. Marx Jun 2007

Moldboard Plowing Following Compost Application Significantly Reduces Nutrient Transport, John E. Gilley, Bahman Eghball, David B. Marx

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

The excessive application of manure on cropland areas can cause nutrients to accumulate near the soil surface and increase nutrient transport by overland flow. Inverting soils with high surface nutrient content could reduce runoff nutrient transport. This study was conducted to measure the effects of moldboard plowing on the redistribution of nutrients within the soil profile and nutrient transport by overland flow. Composted beef cattle manure was applied at dry weights of 0, 68, 105, 142, and 178 Mg ha-1 to a silty clay loam soil and then incorporated by disking. Selected plots were moldboard plowed 244 days later …

Microwave Pretreatment Of Switchgrass To Enhance Enzymatic Hydrolysis, Deepak R. Keshwani, Jay J. Cheng, Joseph C. Burns, Laigeng Li, Vincent Chiang

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Switchgrass is a promising lignocellulosic biomass for fuel-ethanol production. However, pretreatment of lignocellulosic materials is necessary to improve its susceptibility to enzymatic hydrolysis. The objectives of this study were to examine the feasibility of microwave pretreatment to enhance enzymatic hydrolysis of switchgrass and to determine the optimal pretreatment conditions. Switchgrass samples immersed in water, dilute sulfuric acid and dilute sodium hydroxide solutions were exposed to microwave radiation at varying levels of radiation power and residence time. Pretreated solids were enzymatically hydrolyzed and reducing sugars in the hydrolysate were analyzed. Microwave radiation of switchgrass at lower power levels resulted in more …

Short-Term Effects Of A Prescribed Burn On Songbirds And Vegetation In Mountain Big Sagebrush, Aaron L. Holmes Jun 2007

Short-Term Effects Of A Prescribed Burn On Songbirds And Vegetation In Mountain Big Sagebrush, Aaron L. Holmes

Western North American Naturalist

I measured songbird abundance and vegetation cover in and around a 420-ha prescribed burn in a mountain big sagebrush community located at 2133 m elevation. Data were collected during the 3rd growing season after the fire. Brewer's Sparrow and Sage Thrasher occurred in lower abundance on sites that were largely or completely burned relative to sites that were outside the fire perimeter or within unburned islands of shrubs. The number of Brewer's Sparrow detections was linearly related to remaining sagebrush cover. In contrast, Horned Lark occurred at higher abundances on sites where shrub cover had been removed in the prescribed …

Effects Of Prescribed Fall Burning On A Wetland Plant Community, With Implications For Management Of Plants And Herbivores, Scott R. Mcwilliams, Todd Sloat, Catherine A. Toft, Daphne Hatch Jun 2007

Effects Of Prescribed Fall Burning On A Wetland Plant Community, With Implications For Management Of Plants And Herbivores, Scott R. Mcwilliams, Todd Sloat, Catherine A. Toft, Daphne Hatch

Western North American Naturalist

An important contemporary challenge for adaptive resource management is assessing both the direct and indirect effects of management activities by designing appropriate monitoring programs and sound analysis methods. Here we evaluate the effects of prescribed fall burning on a wetland plant community that is managed primarily for spring-migrating geese. During late fall in 2 consecutive years, we burned vegetation in 4 replicate blocks (2.3 ha each) that traversed a natural moisture and associated vegetation gradient. We used ordination, gradient analysis, and contingency table analysis to evaluate how annual changes in relative abundance of plants were affected by burning as well …

Methodological Issues In The Study Of The Effects Of Hemoglobin Variability, Marshall Joffe, Wei Yang, Steve Brunelli, Harold Feldman Jun 2007

Methodological Issues In The Study Of The Effects Of Hemoglobin Variability, Marshall Joffe, Wei Yang, Steve Brunelli, Harold Feldman

UPenn Biostatistics Working Papers

We consider estimating the effect of hemoglobin variability on mortality in hemodialysis patients. Causal effects can be defined as comparisons of outcomes under different hypothetical interventions. Defining measures of the effect of hemoglobin variability and clinical outcomes is complicated by the fact that hypothetical interventions on variability used to define its effect inevitably involve manipulation of related variables. We propose a model-based definition of the effect of the hemoglobin variability as a parameter for variability in a causal model for the effect of an overall intervention on hemoglobin levels over time. We consider this problem using history-adjusted marginal structural models, …
