Outrelativizing Relativism: A Liberal Defense Of The Universality Of International Human Rights, Robert D. Sloane Jan 2001

Outrelativizing Relativism: A Liberal Defense Of The Universality Of International Human Rights, Robert D. Sloane

Vanderbilt Journal of Transnational Law

This Article seeks to provide a new framework, rooted in classical liberalism, for understanding and defending the universality of international human rights. After reviewing the philosophical and historical development of the idea of universality, Part II argues that none of the traditional justifications for conceiving of international human rights as universal succeed. Cultural pluralism therefore must be accepted as a descriptive truth. But to acknowledge the cultural contingency of values as a descriptive claim does not, by itself, undermine the normative claim that human rights are, or should be, universal. Instead, it points to the need to justify universality within …

A Quiet Faith? Taxes, Politics, And The Privatization Of Religion, Richard W. Garnett Jan 2001

A Quiet Faith? Taxes, Politics, And The Privatization Of Religion, Richard W. Garnett

Journal Articles

The government exempts religious associations from taxation and, in return, restricts their putatively political expression and activities. This exemption-and-restriction scheme invites government to interpret and categorize the means by which religious communities live out their vocations and engage the world. But government is neither well-suited nor to be trusted with this kind of line-drawing. What's more, this invitation is dangerous to authentically religious consciousness and associations. When government communicates and enforces its own view of the nature of religion - i.e., that it is a private matter - and of its proper place - i.e., in the private sphere, not …

The Story Of Henry Adams' Soul: Education And The Expression Of Associations, Richard W. Garnett Jan 2001

The Story Of Henry Adams' Soul: Education And The Expression Of Associations, Richard W. Garnett

Journal Articles

In several decisions handed down during its 1999 Term, the United States Supreme Court focused on the freedom of expressive association. Generally speaking, expressive association is regarded by courts and commentators as just another form of individual self-expression, and voluntary associations as facilitators for such self-expression.
/="/">
/="/">In this Essay, Professor Garnett suggests that a shift in focus, from individual self-expression-through-association to the expression of voluntary associations themselves. It is suggested that, in several recent decisions ­including Dale, Mitchell, and California Democratic Party - the Court has indicated an appreciation of the role played by mediating institutions in shaping …

Basicranial Anatomy Of The Living Linsangs Prionodon And Poiana (Mammalia, Carnivora, Viverridae), With Comments On The Early Evolution Of Aeluroid Carnivorans, Robert M. Hunt Jr. Jan 2001

Basicranial Anatomy Of The Living Linsangs Prionodon And Poiana (Mammalia, Carnivora, Viverridae), With Comments On The Early Evolution Of Aeluroid Carnivorans, Robert M. Hunt Jr.

Department of Earth and Atmospheric Sciences: Faculty Publications

The living Asian linsang, Prionodon pardicolor, shares marked anatomical similarities in basicranium and dentition with the extinct Oligocene aeluroid, Palaeoprionodon lamandini, from the Quercy fissures, France. The living African linsang, Poiana richardsoni, is similar yet slightly more derived in basicranial traits relative to Prionodon pardicolor, and also has basicranial and dental features indicating a relationship to the living genets (Genetta). The basicranial and auditory anatomy of a series Palaeoprionodon-Prionodon-Poiana can be interpreted as a morphocline showing the progressive alteration of the form of the petrosal and auditory bulla from the plesiomorphic aeluroid state in …

Spellbinding Performance: Poet As Witch In Theocritus' Second Idyll And Apollonius' Argonautica, Anne Duncan Jan 2001

Spellbinding Performance: Poet As Witch In Theocritus' Second Idyll And Apollonius' Argonautica, Anne Duncan

Department of Classics and Religious Studies: Faculty Publications

The connection between poetry and enchantment in Greek literature is by now a familiar subject. The poet enchants (θέλει) his audience as a magician chants a spell or administers a drug, causing pleasure and the forgetfulness of pain in the listener. As with most other poetic topoi, this one goes back to Homer, to figures like Circe, the Sirens, and even Helen. In this paper, I will argue that two witches from Hellenistic poems should be regarded as poet-figures: Simaetha in Theocritus' Idyll 2, and Medea in Apollonius' Argonautica. Theocritus and Apollonius use the performing female voice of the witch …

Mitochondrial Phylogeography, Subspecific Taxonomy, And Conservation Genetics Of Sandhill Cranes (Grus Canadensis; Aves: Gruidae), Judith M. Rhymer, Matthew G. Fain, Jane E. Austin, Douglas H. Johnson, Carey Krajewski Jan 2001

Mitochondrial Phylogeography, Subspecific Taxonomy, And Conservation Genetics Of Sandhill Cranes (Grus Canadensis; Aves: Gruidae), Judith M. Rhymer, Matthew G. Fain, Jane E. Austin, Douglas H. Johnson, Carey Krajewski

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Six subspecies of sandhill cranes (Grus canadensis) have been denoted based on perceived morphological and/or breeding locality differences among them. Three subspecies are migratory, breeding from the high arctic in North America and Siberia (lesser sandhill, G. c. canadensis), south through central Canada (Canadian sandhill, G. c. rowani) and into the northern United States (greater sandhill, G. c. tabida). A review of sandhill crane taxonomy indicates that the size variation, on the basis of which these subspecies were named, may be clinal and not diagnostic. The other three subspecies, all listed as endangered or threatened, …

Use Of Macroinvertebrates To Identify Cultivated Wetlands In The Prairie Pothole Region, Ned H. Euliss Jr., David M. Mushet, Douglas H. Johnson Jan 2001

Use Of Macroinvertebrates To Identify Cultivated Wetlands In The Prairie Pothole Region, Ned H. Euliss Jr., David M. Mushet, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We evaluated the use of macroinvertebrates as a potential tool to identify dry and intensively farmed temporary and seasonal wetlands in the Prairie Pothole Region. The techniques we designed and evaluated used the dried remains of invertebrates or their egg banks in soils as indicators of wetlands. For both the dried remains of invertebrates and their egg banks, we weighted each taxon according to its affinity for wetlands or uplands. Our study clearly demonstrated that shells, exoskeletons, head capsules, eggs, and other remains of macroinvertebrates can be used to identify wetlands, even when they are dry, intensively farmed, and difficult …

Human Herpesvirus 8 Can Be Transmitted Through Blood In Drug Addicts, Carlos Sosa, Jorge Benetucci, Colleen Hanna, Laura Sieczkowski, Gabriel Deluchi, Ana Maria Canizal, Hamakwa Mantina, Winslow Klaskala, Marianna Baum, Charles Wood Jan 2001

Human Herpesvirus 8 Can Be Transmitted Through Blood In Drug Addicts, Carlos Sosa, Jorge Benetucci, Colleen Hanna, Laura Sieczkowski, Gabriel Deluchi, Ana Maria Canizal, Hamakwa Mantina, Winslow Klaskala, Marianna Baum, Charles Wood

Nebraska Center for Virology: Faculty Publications

Human Herpes virus type-8 (HHV-8) seroprevalence was studied in a population of HIV positive intravenous drug users (IVDUs) from Argentina. Analysis of this population also indirectly made it possible to study HHV-8 blood transmission, because these individuals frequently engage in needle sharing behavior and are capable of acquiring a broad array of blood borne pathogens, including Hepatitis B/C virus. The seroprevalence of HHV-8 in IVDUs was compared to a group of non-IVDUs and HIV negative individuals. Of the 223 individuals tested, 13.45% were HHV-8 positive, 16.99% in the IVDUs group, and 5.71% in the non-IVDUs. Among HIV positive IVDUs, 25/144 …

Duck Populations As Indicators Of Landscape Condition In The Prairie Pothole Region, Jane Austin, Thomas K. Buhl, Glenn R. Guntenspergen, Wayne Norling, H. Thomas Sklebar Jan 2001

Duck Populations As Indicators Of Landscape Condition In The Prairie Pothole Region, Jane Austin, Thomas K. Buhl, Glenn R. Guntenspergen, Wayne Norling, H. Thomas Sklebar

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Prairie Pothole Region of the northern Great Plains is an important region for waterfowl production because of the abundance of shallow wetlands. The ecological significance of the region and impacts from intensive agriculture prompted the U.S. Environmental Protection Agency to select it as one of the first areas for developing and evaluating ecological indicators of wetland condition. We examined hypothesized relations between indicators of landscape and wetland conditions and waterfowl abundance on 45 40 km2 study sites in North Dakota for 1995–1996. Landscape condition was defined a priori as the ratio of cropland area to total upland area …

Estimated Areal Extent Of Colonies Of Black-Tailed Prairie Dogs In The Northern Great Plains, John Sidle, Douglas Johnson, Betty Euliss Jan 2001

Estimated Areal Extent Of Colonies Of Black-Tailed Prairie Dogs In The Northern Great Plains, John Sidle, Douglas Johnson, Betty Euliss

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

During 1997-1998, we undertook an aerial survey, with an aerial line-intercept technique, to estimate the extent of colonies of black-tailed prairie dogs (Cynomys ludovicianus) in the northern Great Plains states of Nebraska, North Dakota, South Dakota, and Wyoming. We stratified the survey based on knowledge of colony locations, computed 2 types of estimates for each stratum, and combined ratio estimates for high-density strata with average density estimates for low-density strata. Estimates of colony areas for black-tailed prairie dogs were derived from the average percentages of lines intercepting prairie dog colonies and ratio estimators. We selected the best estimator …

Fungal Symbiosis From Mutualism To Parasitism: Who Controls The Outcome, Host Or Invader?, Regina S. Redman, David Dunigan, Rusty J. Rodriguez Jan 2001

Fungal Symbiosis From Mutualism To Parasitism: Who Controls The Outcome, Host Or Invader?, Regina S. Redman, David Dunigan, Rusty J. Rodriguez

Department of Plant Pathology: Faculty Publications

• Plant symbiotic fungi are generally thought to express a single lifestyle that might increase (mutualism), decrease (parasitism), or have no influence (commensalism) on host fitness. However, data are presented here demonstrating that plant pathogenic Colletotrichum species are able to asymptomatically colonize plants and express nonpathogenic lifestyles.

• Experiments were conducted in growth chambers and plant colonization was assessed by emergence of fungi from surface sterilized plant tissues. Expression of symbiotic lifestyles was assessed by monitoring the ability of fungi to confer disease resistance, drought tolerance and growth enhancement.

• Several pathogenic Colletotrichum species expressed either mutualistic or commensal lifestyles …

Experimental Infection Of Nontarget Species Of Rodents And Birds With Brucella Abortus Strain Rb51 Vaccine, Matt C. Januszewski, Steven C. Olsen, Robert G. Mclean, Larry Clark, Jack C. Rhyan Jan 2001

Experimental Infection Of Nontarget Species Of Rodents And Birds With Brucella Abortus Strain Rb51 Vaccine, Matt C. Januszewski, Steven C. Olsen, Robert G. Mclean, Larry Clark, Jack C. Rhyan

United States Department of Agriculture Wildlife Services: Staff Publications

The Brucella abortus vaccine strain RB51 (SRB51) is being considered for use in the management of brucellosis in wild bison (Bison bison) and elk (Cervus elaphus) populations in the Greater Yellowstone Area (USA). Evaluation of the vaccine’s safety in non-target species was considered necessary prior to field use. Between June 1998 and December 1999, ground squirrels (Spermophilus richardsonii, n=21), deer mice (Peromyscus maniculatus, n=14), prairie voles (Microtus ochrogaster, n=21), and ravens (Corvus corax, n=13) were orally inoculated with SRB51 or physiologic saline.

Serological Responses Of Coyotes To Two Commercial Rabies Vaccines, Frederick F. Knowlton, Marianna Roetto, Deborah Briggs Jan 2001

Serological Responses Of Coyotes To Two Commercial Rabies Vaccines, Frederick F. Knowlton, Marianna Roetto, Deborah Briggs

United States Department of Agriculture Wildlife Services: Staff Publications

Between August 1993 and September 1994 we documented serological responses of coyotes (Canis latrans) vaccinated with two commercial rabies vaccines licensed for use in domestic dogs. Serologic responses were documented by testing for rabies virus neutralizing antibodies with the rapid fluorescent focus inhibition test (RFFIT) at 30, 90, 180, 270, and 365 days post-vaccination. All coyotes vaccinated with Imrab 3® (Rhone-Merieux, Inc.), and 75% of those vaccinated with Dura-Rab 3® (Immunovet, Inc.) seroconverted, as evidenced by the presence of antirabies antibody titers ≥1:5 in one or more of the five post-vaccination samples. The percent of coyotes …

Phosphorus Risk Assessment Index Evaluation Using Runoff Measurements, Bahman Eghball, John E. Gilley Jan 2001

Phosphorus Risk Assessment Index Evaluation Using Runoff Measurements, Bahman Eghball, John E. Gilley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

An index to evaluate the phosphorus (P) pollution potential of agricultural fields was proposed by Lemunyon and Gilbert in 1993. Data from three rainfall simulation studies were used to evaluate the relative importance of the variables in the P index. These studies included plots containing sorghum (Sorghum bicolor L.), winter wheat (Triticum aestivum L.), and corn (Zea mays L.) residues on which chemical fertilizer and composted or noncomposted beef cattle feedlot manure were applied under no-till and disked conditions. The factors of erosion, runoff, soil P level P application source, and method, and rate of P addition …

Application Of Fuzzy Logic In Automated Cow Status Monitoring, R. M. De Mol, Wayne Woldt Jan 2001

Application Of Fuzzy Logic In Automated Cow Status Monitoring, R. M. De Mol, Wayne Woldt

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Sensors that measure yield, temperature, electrical conductivity of milk, and animal activity can be used for automated cow status monitoring. The occurrence of false-positive alerts, generated by a detection model, creates problems in practice. We used fuzzy logic to classify mastitis and estrus alerts; our objective was to reduce the number of false-positive alerts and not to change the level of detected cases of mastitis and estrus. Inputs for the fuzzy logic model were alerts from the detection model and additional information, such as the reproductive status. The output was a classification, true or false, of each alert. Only alerts …

Way-Finding And Landmarks: The Multiple Bearings Hypothesis, Alan C. Kamil, Ken Cheng Jan 2001

Way-Finding And Landmarks: The Multiple Bearings Hypothesis, Alan C. Kamil, Ken Cheng

Papers in Behavior in Biological Sciences

Clark’s nutcrackers (Nucifraga columbiana) are capable of very precise searching using the metric relationships between a goal and multiple landmarks to relocate the goal location. They can judge the direction more accurately than the distance to a landmark when the landmark is distant from the goal. On the basis of these findings, we propose that nutcrackers use a set of bearings, each a measure of the direction from the goal to a different landmark, when searching for that goal. The results of a simulation demonstrate that increasing the number of landmarks used results in increasingly precise searching. This …

Search For A Hidden Goal By Clark's Nutcrackers (Nucifraga Columbiana) Is More Accurate Inside Than Outside A Landmark Array, Brett M. Gibson, Alan C. Kamil Jan 2001

Search For A Hidden Goal By Clark's Nutcrackers (Nucifraga Columbiana) Is More Accurate Inside Than Outside A Landmark Array, Brett M. Gibson, Alan C. Kamil

Papers in Behavior in Biological Sciences

In three experiments in which an open-room delayed response task was used, we explored how Clark's nutcrackers use landmarks to search for a hidden goal when multiple potential goal locations were present. In Experiment 1, nutcrackers presented with three spatial samples were able to use relative local cues from an array that changed positions throughout a session to return to a hidden goal during a test. In Experiment 2, the number of samples varied from one to three prior to the test. The nutcrackers performed as well with one sample as with two or three samples. In Experiment 3, we …

The Use Of Relative And Absolute Bearings By Clark's Nutcrackers, Nucifraga Columbiana, Juli E. Jones, Alan C. Kamil Jan 2001

The Use Of Relative And Absolute Bearings By Clark's Nutcrackers, Nucifraga Columbiana, Juli E. Jones, Alan C. Kamil

Papers in Behavior in Biological Sciences

Two groups of Clark's nutcrackers were trained to find buried seeds whose location was defined by a constant angle from two landmarks whose interlandmark distance and position in the room varied across trials. The first group had a landmark array that was always placed in the same orientation with respect to the walls, allowing the animals to use both relative and absolute bearings. The second group had a landmark array that rotated across trials so that only relative bearings could be used to locate the seeds. The birds in each group learned the task and transferred to new interlandmark distances …

Review Of Evolution And Cognition, Edited By Cecilia Heyes And Ludwig Huber., Alan Kamil Jan 2001

Review Of Evolution And Cognition, Edited By Cecilia Heyes And Ludwig Huber., Alan Kamil

Papers in Behavior in Biological Sciences

Heyes and Huber have edited a volume that surveys much of the current research into cognition in animals, reflecting the strengths and weaknesses of this field. The book is divided into five sections. In the first part, titled “Orientations,” four authors lay out their basic general views of the field. The first two chapters in this section are by the editors. First, Heyes makes the case for an approach to evolutionary psychology that she labels “in the round,” an approach that would encompass studies of human and nonhuman animals alike and include a broad range of contemporary evolutionary approaches. This …

The Wasp-Like Protein Scar Regulates Macropinocytosis, Phagocytosis And Endosomal Membrane Flow In Dictyostelium, David J. Seastone, Ed Harris, Lesly A. Temesvari, James E. Bear, Charles L. Saxe, James Cardelli Jan 2001

The Wasp-Like Protein Scar Regulates Macropinocytosis, Phagocytosis And Endosomal Membrane Flow In Dictyostelium, David J. Seastone, Ed Harris, Lesly A. Temesvari, James E. Bear, Charles L. Saxe, James Cardelli

Department of Biochemistry: Faculty Publications

Scar, a member of the WASp protein family, was discovered in Dictyostelium discoideum during a genetic screen for second-site mutations that suppressed a developmental defect. Disruption of the scar gene reduced the levels of cellular F-actin by 50%. To investigate the role of Scar in endocytosis, phagocytosis and endocytic membrane trafficking, processes that depend on actin polymerization, we have analyzed a Dictyostelium cell line that is genetically null for Scar. Rates of fluid phase macropinocytosis and phagocytosis are significantly reduced in the scar- cell-line. In addition, exocytosis of fluid phase is delayed in these cells and movement of fluid …

Selenoprotein Oxidoreductase With Specificity For Thioredoxin And Glutathione Systems, Qi-An Sun, Leo Kirnarsky, Simon Sherman, Vadim N. Gladyshev Jan 2001

Selenoprotein Oxidoreductase With Specificity For Thioredoxin And Glutathione Systems, Qi-An Sun, Leo Kirnarsky, Simon Sherman, Vadim N. Gladyshev

Department of Biochemistry: Faculty Publications

Thioredoxin (Trx) and glutathione (GSH) systems are considered to be two major redox systems in animal cells. They are reduced by NADPH via Trx reductase (TR) or oxidized GSH (GSSG) reductase and further supply electrons for deoxyribonucleotide synthesis, antioxidant defense, and redox regulation of signal transduction, transcription, cell growth, and apoptosis. We cloned and characterized a pyridine nucleotide disulfide oxidoreductase, Trx and GSSG reductase (TGR), that exhibits specificity for both redox systems. This enzyme contains a selenocysteine residue encoded by the TGA codon. TGR can reduce Trx, GSSG, and a GSH-linked disulfide in in vitro assays. This unusual substrate specificity …

Contrasting Effects Of Plant Richness And Composition On Insect Communities: A Field Experiment, Nick M. Haddad, David Tilman, John Haarstad, Mark Ritchie, Johannes M.H. Knops Jan 2001

Contrasting Effects Of Plant Richness And Composition On Insect Communities: A Field Experiment, Nick M. Haddad, David Tilman, John Haarstad, Mark Ritchie, Johannes M.H. Knops

School of Biological Sciences: Faculty Publications

We experimentally separated the effects of two components of plant diversity—plant species richness and plant functional group richness—on insect communities. Plant species richness and plant functional group richness had contrasting effects on insect abundances, a result we attributed to three factors. First, lower insect abundances at higher plant functional group richness were explained by a sampling effect, which was caused by the increasing likelihood that one low-quality group, C4 grasses, would be present and reduce average insect abundances by 25%. Second, plant biomass, which was positively related to plant functional group richness, had a strong, positive effect on insect abundances. …
