Games Economists Play, Rochelle C. Dreyfuss

Vanderbilt Law Review

When Professor Reichman called me about this symposium, I was intrigued. With the successive introduction of the photocopy machine, the videotape, computerization, digitization, the Internet, as well as a host of biotechnological discoveries, the problems facing the creative industries have changed dramatically. This accumulation of developments has altered the economic foundations on which intellectual property law is based and has pushed those of us in the field into a period of reconceptualization in which economic analysis is particularly fruitful. Thus, I was quite taken with the idea of bringing intellectual property and economics scholars together to promulgate a research agenda …

From Hopeful Monsters To Homeotic Effects: Richard Goldschmidt's Integration Of Development, Evolution, And Genetics, Michael Dietrich

Dartmouth Scholarship

Richard Goldschmidts research on homeotic mutants from 1940 until his death in 1958 represents one of the first serious efforts to integrate genetics, development, and evolution. Using two different models, Goldschmidt tried to show how different views of genetic structure and gene action could provide a mechanism for rapid speciation. Developmental systems were emphasized in one model and a hierarchy of genetic structures in the other. While Goldschmidt tried to find a balance between development and genetics, critics, such as Sewall Wright, urged him and eventually helped him incorporate population dynamics into his models as well. As such, the history …

The Infall Region Of Abell 576: Independent Mass And Light Profiles, Kenneth Rines, Margaret J. Geller, Antonaldo Diaferio, Joseph J. Mohr, Gary A. Wegner

Dartmouth Scholarship

We describe observations of the nearby (cz = 11,487 km s^-1) cluster of galaxies Abell 576 beyond the virial radius and into the infall region where galaxies are on their first or second pass through the cluster. Using 1057 redshifts, we use the infall pattern in redshift space to determine the mass profile of A576 to a radius of ~4 h^-1 Mpc. This mass estimation technique makes no assumptions about the equilibrium state of the cluster. Within ~1 h^-1 Mpc, the mass profile we derive exceeds that determined from X-ray observations by a factor of …

The Exclusion Of Hiv-Positive Immigrants Under The Nicaraguan Adjustment And Central American Relief Act And The Haitian Refugee Immigration Fairness Act, Statutory Interpretation, Communicable Disease, Public Health, Legislative Intent, Shayna S. Cook

Michigan Law Review

The United States has turned away immigrants infected with the human immunodeficiency virus ("HIV") under the public health exclusion of the Immigration and Nationality Act ("INA") since the mid-1980's. Since Congress codified the HIV exclusion in 1993, any alien applying for an immigrant or nonimmigrant visa, adjustment of status to lawful permanent resident, or refugee status must first have a blood test for HIV. The HIV exclusion is not absolute, however. Each HIV-positive alien can apply for one of two waivers of the HIV exclusion that are available in the INA. When an alien applies for immigrant or permanent resident …

Shubnikov–De Haas Effect In The Superconducting State Of An Organic Superconductor, J. Wosnitza, S. Wanka, J. Hagel, R. Häussler, H. V. Löhneysen, J. A. Schlueter, U. Geiser, P. G. Nixon, Rolf Walter Winter, Gary L. Gard

Chemistry Faculty Publications and Presentations

We report the observation of Shubnikov–de Haas (SdH) oscillations in the mixed state of the organic superconductor β″-(BEDT-TTF)₂SF₅CH₂CF₂SO₃ (Tc≈4.4K). At low temperatures the SdH oscillations persist clearly below the upper critical field Bc₂(0)≈3.6 T almost down to the field where the resistivity vanishes. Rather unusually, no additional damping of the SdH-signal amplitude — as well as of the de Haas–van Alphen amplitude — is observed in the superconducting state. This indicates that the damping in the vortex state of this quasi-two-dimensional superconductor is different in character to that observed for most three-dimensional materials.

Detection Of Solid Pigment In Dermatoscopy Images Using Texture Analysis, Murali Anantha, William V. Stoecker, Randy Hays Moss

Chemistry Faculty Research & Creative Works

Background/aims: Epiluminescence microscopy (ELM), also known as dermoscopy or dermatoscopy, is a non-invasive, in vivo technique, that permits visualization of features of pigmented melanocytic neoplasms that are not discernable by examination with the naked eye. ELM offers a completely new range of visual features. One such feature is the solid pigment, also called the blotchy pigment or dark structureless area. Our goal was to automatically detect this feature and determine whether its presence is useful in distinguishing benign from malignant pigmented lesions.

Methods: Here, a texture-based algorithm is developed for the detection of solid pigment. The factors d and a …

Cerium Liii-Edge X-Ray Absorption Study Of The Ceₓfe4-YCoYSb₁₂ Skutterudites, Fernande Grandjean, Gary J. Long, Robert Cortès, Donald T. Morelli, Gregory P. Meisner

Chemistry Faculty Research & Creative Works

The cerium L_III-edge x-ray absorption near-edge spectra of the Ce_xFe_4-yCo_ySb₁₂ compounds have been obtained at 295 K and unambiguously indicate that cerium is in the 4f¹ electronic ground state for all values of 0.22≤x≤0.98 and 0.0≤y≤3.5. This stable trivalent state of cerium is in agreement with the proposed (CeFe₄Sb₁₂) _1-α(Co₄Sb₁₂)α, solid solution structure, in which the cerium atoms are always surrounded by twelve antimony first neighbors and six iron second neighbors, the observed magnetic properties of CeFe₄Sb₁₂ and …

Mössbauer Spectral Study Of The Magnetic Properties Of Ce₂Fe₁₇Hₓ (X=0, 1, 2, 3, 4, And 5), Dimitri Hautot, Gary J. Long, Fernande Grandjean, Olivier Isnard

Chemistry Faculty Research & Creative Works

The Mössbauer spectra of Ce₂Fe₁₇H_x, where x=0, 1, 2, 3, 4, and 5, have been measured and analyzed between 4.2 and 295 K. Because Ce₂Fe₁₇ exhibits a helical magnetic order between 225 and 90 K and a fan magnetic order below 90 K, its Mössbauer spectra were fit with a distribution of hyperfine fields and θ angles for four of the eight magnetically inequivalent sites. Because the hydrides exhibit a magnetization within the basal plane of the hexagonal cell, their Mössbauer spectra were fit with seven sextets. The four isomer shifts …

Second-Harmonic And Sum-Frequency Imaging Of Organic Nanocrystals With Photon Scanning Tunneling Microscope, Yuzhen Shen, Jacek Swiatkiewicz, Jeffrey G. Winiarz, Przemyslaw P. Markowicz, Paras N. Prasad

Chemistry Faculty Research & Creative Works

Second-harmonic generation and sum-frequency generation with photon scanning tunneling microscopy and shear-force detection are used to map the nonlinear optical response and the surface topograph of N-(4-nitrophenyl)-(L)-prolinol crystals with a subdiffraction-limited resolution. The domain-size dependence of the spatial feature is obtained, which shows the local orientational distribution of the optical near field radiated by nonlinear nanocrystals and reveals the difference between nanoscopic and macroscopic second-order optical nonlinearities of molecular crystals.

High Performance Micropane Electron Beam Window, Roger A. Dougal, Shengyi Liu

Faculty Publications

A silicon disk etched so that it contains a multitude of microscopic and thin window panes (micropanes) can potentially transmit a larger average electron beam current density and absorb a smaller fraction of the beam energy than a common metal foil window. The enhanced performance is achieved by a combination of decreased power loss due to the extremely small window thickness (~1 μm), and increased conductive cooling due to the small diameter (~50 μm) of the micropanes and the large cross section of the honeycomb structure that supports the micropanes. Beam current densities up to 34 A/cm2 are permitted within …

Permeabilization Of Cochliomyia Hominivorax (Diptera: Calliphoridae) Embryos, Dennis Berkebile, Jan Chirico, Roger A. Leopold

Department of Entomology: Faculty Publications

Embryos of the primary screwworm, Cochliomyia hominivorax (Coquerel), were successfully permeabilized for use in subsequent cryopreservation studies. Mortality was greater for eggs incubated for<5 h before treatment. The mean survival of embryos to first instars was 55.7, 61.1, and 62.6% when the embryos were incubated for 5, 5.5, and 6 h before treatment, respectively. The survival to the pupal and adult stages was low. An improved media for culturing the embryos during and immediately after treatment needs to be devised and the procedure for rearing the larval stages also needs to be altered to improve survival for emerging adults.

Electrophysiological Studies Of Olfaction In The Whip Spider Phrynus Parvulus (Arachnida, Amblypygi), Eileen Hebets, Reginald F. Chapman

Eileen Hebets Publications

The olfactory response of the whip spider Phrynus parvulus from Costa Rica was examined using a technique analogous to that used for insect electroantennograms on the tarsi of the antenniform legs which bear multiporous sensilla. Responses to 42 chemicals representing different chain lengths of alkanes, carboxylic acids, alcohols, aldehydes, and ketones, as well as some esters, monoterpenes, and phenolics were examined. Fifty-four percent of the chemicals tested elicited responses. Concentration–response curves were generated for guaiacol, hexanal, methyl salicylate, benzaldehyde, octanoic acid, and linalool. Guaiacol, benzaldehyde, and hexanol elicited the greatest responses and no differences were detected between the sexes. Compounds …

Subcutaneous Panniculitic T Cell Lymphoma Mimicking Histiocytic Cytophagic Panniculitis In A Child, Sulafa K. Ali, Nadir M. Othman, Alexander B. Tagoe, Asma A. Tulba

Saudi Medical Journal

Subcutaneous panniculitc T-cell lymphoma is a very rare malignancy in the pediatric age group, its association with hemophagocytic syndrome had been described but the association with the skin lesions mimicking histiocytic cytophagic panniculitis which is characteristic of hemophagocytic syndrome has not, to our knowledge, been described in children. We report a child with panniculitic T-cell lymphoma associated with bone marrow hemophagocytosis and subcutaneous histiocytic infiltration with active phagocytosis simulating histiocytic cytophagic. We stress the importance of searching for T-cell lymphoma in patients with panniculitis and hemophagocytic syndrome.

Bronchiolitis Obliterans Organizing Pneumonia Associated With Pseudomonas Aeruginosa Infection, Daad H. Akbar, Omer S. Alamoudi

Saudi Medical Journal

Bronchiolitis obliterans organizing pneumonia is a rare disease characterized by the presence of granulation tissue within alveolar ducts and alveoli. Most cases are idiopathic, but it may also be seen during resolution of viral or bacterial pneumonia (mycoplasma, legionella and chlamydia). It may present as a community acquired pneumonia which does not respond to antibiotics, which make the diagnosis very difficult. We described a 53-year old patient who presented with Bronchiolitis obliterans organizing pneumonia during the resolution of pseudomonas aeruginosa pneumonia. Initially there was slight improvement on antibiotics but later he became severely hypoxic and placed on mechanical ventilator. Diagnosis …

Gastric Perforation. An Unusual Cause Of Ascites In A Newborn Baby, Omer B. Abdelbasit, Meeralebbae M. Shaheed, Mohammad S. Al-Omari, Abdullah M. Abomelha, Mirghani O. Babiker

Saudi Medical Journal

We report a case of a low birth weight asymmetrical small for gestational age baby, who presented at the age of 20 hours with sudden abdominal distension. Since birth he has been breastfed and was kept with his mother. Absence of radiological findings of necrotizing enterocolitis or perforation at the time of presentation delayed the diagnosis for 48 hours. At laparotomy the baby was found to have perforation of the stomach with no evidence of other gastrointestinal disorder.

Correlation Of A Social Skills Self-Rating Survey And A Teacher Rating Inventory For Students At A Residential School For The Deaf, James Thomas Haley

Student Work

Students aged 12 to 15 at a Midwestern residential school for the deaf completed the Matson Evaluation of Social Skills for Deaf and Hard-of-Hearing Youngsters (MESSY- DHH). Faculty at the school completed the Meadow Kendall Social Emotional Assessment Inventory (SEAI) to rate the behavior of the same students. Pearson’s correlations were conducted to determine if relationships existed between scores on the MESSY-DHH and the SEAI. Results indicated inconsistent correlations between scores on the MESSY-DHH and individual scale scores on the SEAI.

Rhizosphere Competitiveness Of Trichloroethylene-Degrading, Poplar-Colonizing Recombinant Bacteria, Hojae Shim, Sadhana Chauhan, Doohyun Ryoo, Kally Bowers, Stuart M. Thomas, Keith A. Canada, Thomas K. Wood, Joel Gerard Burken

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Indigenous bacteria from poplar tree (Populus canadensis var. eugenei `Imperial Carolina') and southern California shrub rhizospheres, as well as two tree-colonizing Rhizobium strains (ATCC 10320 and ATCC 35645), were engineered to express constitutively and stably toluene o-monooxygenase (TOM) from Burkholderia cepacia G4 by integrating the tom locus into the chromosome. The poplar and Rhizobium recombinant bacteria degraded trichloroethylene at a rate of 0.8 to 2.1 nmol/min/mg of protein and were competitive against the unengineered hosts in wheat and barley rhizospheres for 1 month (colonization occurred at a level of 1.0 × 10⁵ to 23 × 10^{5 …}
