Inequality And Indignation, Cass R. Sunstein, Edna Ullmann-Margalit

Coase-Sandor Institute for Law & Economics Research Paper Series

Inequalities often persist because both the advantaged and the disadvantaged stand to lose from change. Despite the probability of loss, moral indignation can lead the disadvantaged to seek to alter the status quo, by encouraging them to sacrifice their material self-interest for the sake of equality. Experimental research shows that moral indignation, understood as a willingness to suffer in order to punish unfair treatment by others, is widespread. It also indicates that a propensity to apparently self-defeating moral indignation can turn out to promote people’s material self-interest, if and because others will anticipate their actions. But potential rebels face collective …

Homeland Security: The New Role For Defense, Steven J. Tomisek

Strategic Forums

Before the terrorist attacks of September 11, 2001, U.S. defense forces were principally oriented toward deterrence, overseas stability operations, and traditional warfighting missions, and homeland defense was largely the responsibility of civilian law enforcement agencies. The shock of 9/11 and the emergence of transnational terrorist and bioterror threats prompted a strategic reassessment of the Department of Defense’s role in securing the American homeland. This paper examines how the Department of Defense has adapted to this changing security environment by reaffirming its constitutional role in protecting the United States against foreign aggression, expanding its mission set to include homeland defense, and …

Military Conservation Partnerships, Laura M. Caballero

Master's Projects

The military has unintentionally become a steward of some of our country’s most precious natural resources. Many military installations surrounded by encroaching urbanization have earned reputations for being “islands of biodiversity” (Army Congressional Testimony to Senate Armed Forces Committee, 2001). Military training land provides a safe harbor for wildlife displaced by urban development. In addition, most military installations escape erosion problems caused by high-density development and boast some of the purest wetlands in their communities. Military installations also provide communities with excellent recreation opportunities, from wildlife viewing and hiking to hunting and fishing. The military takes pride in its commitment …

“The Policy Exists But You Can’T Really Use It”: Communication And The Structuration Of Work-Family Policies, Erika L. Kirby, Kathleen J. Krone

Department of Communication Studies: Faculty Publications

Although work-family benefits are increasingly important organizational policies, limited research addresses the impact of communication on benefit utilization. However, communication is significant because the perceived appropriateness of work-family benefits emerges through interaction. For example, when coworkers complain about “picking up the slack” for those using family leave, their discourse may impact future decisions of other workers regarding whether they utilize the work-family benefits available to them. We apply Giddens’ (1984) Structuration Theory to examine organizational members’ discursive responses to conditions (and contradictions) present in utilizing work-family benefits in a governmental organization. We argue the daily discursive practices of individuals can …

Lasers As Non-Lethal Avian Repellents: Potential Applications In The Airport Environment, Bradley F. Blackwell, Glen E. Bernhardt, Jonathon D. Cepek, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Research conducted by the U.S. Department of Agriculture’s (USDA) National Wildlife Research Center (NWRC) indicates that low- to moderate-power, long-wavelength lasers (630- 650 nm) provide an effective means of dispersing some “problem” bird species under low-light conditions, while presenting no threat to the animal or the environment. The NWRC researchers tested the hypothesis that birds would avoid the beam or beam spot produced by a laser in low ambient light. In the format of controlled, replicated, 2-choice experiments with captive birds, Canada geese (Branta canadensis; 6 groups; 4 birds/group) exhibited extreme avoidance of laser beams over 80-minute periods, …

Osmosensitive Release Of Neurotransmitter Amino Acids: Relevance And Mechanisms, Herminia Pasantes-Morales, Rodrigo Franco, Lenin Ochoa, Benito Ordaz

School of Veterinary and Biomedical Sciences: Faculty Publications

Hyposmolarity activates amino acid efflux as part of the corrective volume process in a variety of cells. This review discusses the mechanism of amino acid release in brain cells preparations. Results present evidence of substantial differences between the efflux of taurine and that of GABA and glu-tamate, which besides a possible role as osmolytes, have a main function as synaptic transmitters. The differences found concern the efflux time course, the sensitivity to Cl^– channel blockers, the modulation by tyrosine kinases, the influence of PKC and the effect of cytoskeleton disruptive agents. While taurine efflux features fit well with the …

Visual Predators Select For Crypticity And Polymorphism In Virtual Prey, Alan B. Bond, Alan Kamil

Papers in Behavior in Biological Sciences

Cryptically colored animals commonly occur in several distinct pattern variants. Such phenotypic diversity may be promoted by frequency-dependent predation, in which more abundant variants are attacked disproportionately often, but the hypothesis has never been explicitly tested. Here we report the first controlled experiment on the effects of visual predators on prey crypticity and phenotypic variance, in which blue jays (Cyanocitta cristata) searched for digital moths on computer monitors. Moth phenotypes evolved via a genetic algorithm in which individuals detected by the jays were much less likely to reproduce. Jays often failed to detect atypical cryptic moths, confirming frequency- …

Dictyostelium Lvsb Mutants Model The Lysosomal Defects Associated With Chediak-Higashi Syndrome, Ed Harris, Ning Wang, Wei-I Wu, Alisha Weatherford, Arturo De Lozanne, James Cardelli

Department of Biochemistry: Faculty Publications

Chediak-Higashi syndrome is a genetic disorder caused by mutations in a gene encoding a protein named LYST in humans (“lysosomal trafficking regulator”) or Beige in mice. A prominent feature of this disease is the accumulation of enlarged lysosome-related granules in a variety of cells. The genome of Dictyostelium discoideum contains six genes encoding proteins that are related to LYST/Beige in amino acid sequence, and disruption of one of these genes, lvsA (large volume sphere), results in profound defects in cytokinesis. To better understand the function of this family of proteins in membrane trafficking, we have analyzed mutants disrupted in lvsA, …

Tissue Factor. Biological Function And Clinical Significance, Bashir A. Lwaleed

Saudi Medical Journal

Tissue Factor is the principal cellular initiator of normal blood coagulation. It is frequently encrypted in the plasma membrane of cells in contact with blood, but under certain pathological conditions endothelial cells, monocytes or macrophages may express tissue factor; and hence trigger coagulation activation. Aberrant expression of tissue factor by these cells is thought to be responsible for the thrombophilia found in septic shock, atherosclerosis and cancer. Tissue factor is produced by tumor-associated macrophages where it is believed to play an important role in tumor growth and dissemination. It may also be involved in other cellular processes such as intracellular …

Toxic Effect Of Tannic And Related Compounds On Human Plasma Proteins, Sabah M. Al-Shafi

Saudi Medical Journal

OBJECTIVE: To investigate the toxicity of tannic acid related compounds such as gallic acid and polyphenol on the activity of plasma proteins in vitro. Their electrophoretic results show extremely important information, albumin and globulin levels are remarkably changed and characterized by disorder in their fractions avere which occurred frequently. METHODS: All plasma proteins samples of sets A, B and C were treated in sequences with known different concentrations of gallic acid, gallotannin and polypholes, which were separated chromatographically from phenolic extract of fruit peel of punicaceae. These were then treated, A, B and C were subjected to electrophoresis techniques, for …

Functional Characterization And Localization Of The Aspergillus Nidulan Formin Sepa, Kathryn E. Sharpless, Steven D. Harris

Department of Plant Pathology: Faculty Publications

Formins are a family of multidomain scaffold proteins involved in actin-dependent morphogenetic events. In Aspergillus nidulans, the formin SEPA participates in two actin-mediated processes, septum formation and polarized growth. In this study, we use a new null mutant to demonstrate that SEPA is required for the formation of actin rings at septation sites. In addition, we find that a functional SEPA::GFP fusion protein localizes simultaneously to septation sites and hyphal tips, and that SEPA colocalizes with actin at each site. Using live imaging, we show that SEPA localization at septation sites and hyphal tips is dynamic. Notably, at septation …

Wallinia Chavarriae N. Sp. (Trematoda: Macroderoididae) In Astyanax Aeneus (Günther, 1860) And Bryconamericus Scleroparius (Regan, 1908) (Osteichthyes: Characidae) From The Área De Conservación Guanacaste, Costa Rica, Anindo Choudhury, Rita Hartvigsen Daverdin, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Wallinia chavarriae n. sp. is described from the small-bodied characids Astyanax aeneus and Bryconamericus scleroparius in the Área de Conservación Guanacaste, northwestern Costa Rica. The species differs from W. valenciae in possessing an acetabulum that is smaller than the oral sucker and vitelline follicles that are ovoid or rounded rather than elongate and tubular. Detailed comparison between these two species is handicapped by the less than satisfactory condition of the type and only museum specimen of W. valenciae. Wallinia chavarriae and W. valenciae belong to a subfamily of trematodes, Walliniinae, that arguably includes Creptotrematina spp., Magnivitellum simplex, and …

Thin Filament Diversity And Physiological Properties Of Fast And Slow Fiber Types In Astronaut Leg Muscles, Danny A. Riley, James L. W. Bain, Joyce L. Thompson, Robert H. Fitts, Jeffrey J. Widrick, Scott W. Trappe, Todd A. Trappe, David L. Costill

Biological Sciences Faculty Research and Publications

Slow type I fibers in soleus and fast white (IIa/IIx, IIx), fast red (IIa), and slow red (I) fibers in gastrocnemius were examined electron microscopically and physiologically from pre- and postflight biopsies of four astronauts from the 17-day, Life and Microgravity Sciences Spacelab Shuttle Transport System-78 mission. At 2.5-µm sarcomere length, thick filament density is ~1,012 filaments/µm² in all fiber types and unchanged by spaceflight. In preflight aldehyde-fixed biopsies, gastrocnemius fibers possess higher percentages (~23%) of short thin filaments than soleus (9%). In type I fibers, spaceflight increases short, thin filament content from 9 to 24% in soleus and …

Five Trends In Presidential Rhetoric: An Analysis Of Rhetoric From George Washington To Bill Clinton, Elvin T. Lim

Research Collection School of Social Sciences

Several political scientists have argued that the presidential recourse to public rhetoric as a mode of political influence in the twentieth century represents a significant departure from a pre-twentieth-century institutional norm where “going public” was both rare and frowned upon. This article looks specifically at the changes in the substance of rhetoric that have accompanied this alleged institutional transformation. Applying computer-assisted content analysis to all the inaugural addresses and annual messages delivered between 1789 and 2000, the author identifies and explores five significant changes in twentieth-century presidential rhetoric that would qualifiedly support the thesis of institutional transformation in its rhetorical …
