Swimming Mechanics And Behavior Of The Shallow-Water Brief Squid Lolliguncula Brevis, Ian K. Bartol, Mark R. Patterson, Roger Mann
Swimming Mechanics And Behavior Of The Shallow-Water Brief Squid Lolliguncula Brevis, Ian K. Bartol, Mark R. Patterson, Roger Mann
Biological Sciences Faculty Publications
Although squid are among the most versatile swimmers and rely on a unique locomotor system, little is known about the swimming mechanics and behavior of most squid, especially those that swim at low speeds in inshore waters. Shallow-water brief squid Lolliguncula brevis, ranging in size from 1.8 to 8.9 cm. in dorsal mantle length (DML), were placed in flumes and videotaped, and the data were analyzed using motion-analysis equipment. Flow visualization and force measurement experiments were also performed in water tunnels. Mean critical swimming speeds (Ucrit) ranged from 15.3 to 22.8 cm s-1, and mean …

Blood-Squirting Variability In Horned Lizards (Phrynosoma), Wade Sherbrooke, George Middendorf, C. Guyer
Blood-Squirting Variability In Horned Lizards (Phrynosoma), Wade Sherbrooke, George Middendorf, C. Guyer
Department of Biology Faculty Publications
Variability within the genus Phrynosoma in the occurrence of ocular-sinus blood-squirting, reportedly a defense used in canid encounters, is reviewed from the literature. Six species have been reported to squirt blood, and seven species remain unreported. Five of the latter species were tested in dog trials; one exhibited blood-squirting (Phrynosoma hernandesi), one exhibited precursor behaviors but failed to squirt blood (Phrynosoma ditmarsi), and three yielded negative results (Phrynosoma mcallii, Phrynosoma modestum, and Phrynosoma platyrhinos). Instances of blood-squirting in response to human encounters were collected and largely support the negative results for the three species P. mcallii, P. modestum, and P. …
Asymmetrical Response Of P38 Kinase Activation To Volume Changes In Primary Rat Astrocytes, Dazhong Xu, Ling Wang, James E. Olson, Luo Lu
Asymmetrical Response Of P38 Kinase Activation To Volume Changes In Primary Rat Astrocytes, Dazhong Xu, Ling Wang, James E. Olson, Luo Lu
Emergency Medicine Faculty Publications
Activation of p38 kinase by osmotic stress has been documented in many cells; however, no report has distinguished the effects of cell volume on p38 activity from the effects of the altered osmotic condition per se. Here we report asymmetrical activation of astrocyte p38 mitogen-activated protein (MAP) kinase in response to volume increases and volume decreases. We separate effects of cell volume changes from the effects of osmotic exposure on p38 activation. Exposure to 400, 500, or 600 mOsm phosphate-buffered saline (PBS) caused cell shrinkage and an osmolality-dependent increase in p38 activity to 175%, 409%, or 518%, respectively, compared with …
Killing, Letting Die, And The Alleged Necessity Of Military Intervention, Laurie Calhoun
Killing, Letting Die, And The Alleged Necessity Of Military Intervention, Laurie Calhoun
Peace and Conflict Studies
Recent international developments have introduced the possibility of war waged on behalf of people unable to defend themselves, and when the attacking parties’ interests appear not to be at stake. Are purely military forms of “humanitarian intervention” sometimes morally required? Can such military missions be reconciled with the widely held belief in the moral distinction between killing and letting die? In exploring these questions, the two dominant paradigms in writing about war are considered: just war theory and utilitarianism. The moral centrality of intentions emerges through an explanation of the distinction often made between natural and man-made catastrophe. Ultimately, the …

High Frequency Of Extra-Pair Paternity In Eastern Kingbirds, Diane L. Rowe, Michael T. Murphy, Robert C. Fleischer, Paul G. Wolf
Biology Faculty Publications and Presentations
Genetic parentage in the socially monogamous and territorial Eastern Kingbird( Tyrannust tyrannus) was examined in a central New York population by multilocus DNA fingerprinting. Extra-pair young were identified in 60% (12 of 20) of nests. Of the 64 nestlings profiled, 42% were sired by extra-pair males, but no cases of conspecific brood parasitism were detected. These results are markedly different from a previous electrophoretic study of the same species in a Michigan population, which reported 39% of nestlings were unrelated to one (typically the mother, quasiparasitismo)r both (conspecificb roodp arasitism) of the putative parents. In the New York population, extra-pairp …

Asymmetric Warming Over Coastal California And Its Impact On The Premium Wine Industry, Ramakrishna R. Nemani, Michael A. White, Daniel R. Cayan, Gregory V. Jones, Steven W. Running, Joseph C. Coughlan, David L. Peterson
Numerical Terradynamic Simulation Group Publications
Climatic changes over coastal California from 1951 to 1997 may have benefited the premium wine industry, as seen in higher quality wines and larger grape yields. Observed temperature warming trends were asymmetric, with greatest warming at night and during spring. Warming was associated with large increases in eastern Pacific sea surface temperatures (SST) and amounts of atmospheric water vapor. Although the average annual temperature warming trend was modest (1.13°C/47 yr), there was a 20 d reduction in frost occurrence and a 65 d increase in frost-free growing season length. In the Napa and Sonoma valleys, warmer winter and spring temperatures …

Running Aground On The (Shoal) Waters Of The United States: The Supreme Court Invalidates The Migratory Bird Rule, William F. Northrip
Missouri Law Review
For the better part of the last fifty years, the Commerce Clause provided a safe harbor for congressional legislation. However, the legislative landscape began to change with the Supreme Court’s decision in United States v. Lopez. For the first time in nearly sixty years, an act of Congress was invalidated as exceeding the authority granted to Congress by the commerce Clause. As courts applied the stricter standard announced in Lopez, some regulations began to founder under the newly heightened scrutiny. Among the regulations that struggled in these rough waters was 33 C.F.R. § 328.3, the United States Army Corps of …

Biology Faculty Research
Cadherins are homophilic cell adhesion molecules that control development of a variety of tissues and maintenance of adult structures. Although cadherins have been implicated in the development of the brain, including the visual system, in several vertebrate species, little is known of their role in zebrafish. In this study, we examined distribution of cadherin-2 (Cdh2, N-cadherin) in the visual system of developing and adult zebrafish using both immunocytochemical and in situ hybridization methods, and we compared Cdh2 distribution to that of the previously reported and closely related cadherin-4 (Cdh4, R-cadherin). As in other vertebrates, in zebrafish embryos Cdh2 was widely …

Genetic And Environmental Risk Factors Associated With Colon Cancer, Shamma Rashed Khalfan Al-Naili Al-Shamsi
Genetic And Environmental Risk Factors Associated With Colon Cancer, Shamma Rashed Khalfan Al-Naili Al-Shamsi
Theses
Colorectal cancer represents one of the most common causes of mortality in the world. A major number of populations develop an adenoma by the age of 40s. Over the past years, it has become clear that genetic factors are of crucial importance in colorectal tumorigenesis. Familial adenomatous polyposis (FAP) is responsible of developing numerous colorectal cancers cases by causing mutations in the germline in adenomatous polyposis coli (APC) genes.
Colon cancer is considered the second most frequent cause of death in most of the Western countries. Colonic cancer is common in women and rectal in men. It arise in adenomatous …

Bat Morphology And Pollinator Specificity In A Neotropical Cloud Forest, November 2001, Kiva Rice
Bat Morphology And Pollinator Specificity In A Neotropical Cloud Forest, November 2001, Kiva Rice
Monteverde Institute: Tropical Ecology and Conservation
This study explores the degree of specialization of nectarivorous bat species and the plants they visit by examining pollen loads. The bat species involved are Anoura geoffroyi, Glossophaga commissarisi, and Hylonycteris underwoodi, all of which feed on nectar and are found in the cloud forests of Monteverde. Five nights were spent mist-netting and pollen samples were taken from the head, fore-body and back of each individual caught. These were placed on slides that were observed under a microscope and pollen morphospecies were counted. Twenty-two pollen morphospecies were found and a few were identified. A 1-way ANOVA test was conducted to …

All Dugoni School of Dentistry Faculty Articles
We investigated the molecular mechanisms by which pH-sensitive liposomes surpass the cytoplasmic and endosomal membranes to deliver their aqueous contents into the cytoplasm. Various liposome formulations were evaluated for their efficacy to mediate intracellular delivery of encapsulated material, including a novel sterically stabilized pH-sensitive formulation ((DOPE:CHEMS:DSPE-PEG2000 (6:4:0.3)) that was previously developed in our laboratories. In an attempt to fully characterize the nature of liposome-cell interactions different approaches based on a dual-labeling fluorescence assay were used. Our results indicate that the efficacy of interaction of pH-sensitive liposomes, both plain and sterically stabilized, with cells is strongly determined by the inclusion of …

Rapid Decisive Operations: An Assumptions-Based Critique, Antulio J. Echevarria Dr.
Rapid Decisive Operations: An Assumptions-Based Critique, Antulio J. Echevarria Dr.
Books, Monographs & Collaborative Studies
In support of the Joint community's efforts to develop a viable operational concept, the author argues that the Rapid Decisive Operations (RDO) concepts developers deserve high praise for attempting to link two relative properties--speed and decisiveness--but that the definition of RDO is at present incoherent and based on several deeply flawed assumptions. The author concludes that RDO creates dubious expectations and will likely fail to balance the strengths and weaknesses introduced by new technologies. He further recommends a method for identifying and addressing an operational concept s critical assumptions.

We agree with Obrycki et al. (2001) that a broad-based ecological approach for new pest management technologies is desirable, but we unanimously and strongly disagree with some of their assumptions and conclusions about Bt corn. Bt corn is corn that has been genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis. Because Bt corn is important for effective and ecologically sound management of lepidopteran pests of corn,we provide here relevant data, some of which is new, to help clarify the issues raised by Obrycki et al. (2001). Obrycki et al. (2001), citing Barry and Darrah (1991), claim that …
