Collusive Bidding In The Fcc Spectrum Auctions, Peter Cramton, Jesse Schwartz
Collusive Bidding In The Fcc Spectrum Auctions, Peter Cramton, Jesse Schwartz
Jesse A. Schwartz
This paper describes the bid signaling that occurred in many of the FCC spectrum auctions. Bidders in these auctions bid on numerous spectrum licenses simultaneously, with bidding remaining open on all licenses until no bidder is willing to raise the bid on any license. Simultaneous open bidding allows bidders to send messages to their rivals, telling them on which licenses to bid and which to avoid. This “code bidding” occurs when one bidder tags the last few digits of its bid with the market number of a related license. We examine how extensively bidders signaled each other with retaliating bids …
Subsets More Likely To Benefit From Surgery Or Prophylactic Cranial Irradiation After Chemoradiation For Localized Non-Small-Cell Lung Cancer, Bruce Keith, Mark Vincent, Larry Stitt, Anna Tomiak, Richard Malthaner, Edward Yu, Pauline Truong, Richard Inculet, Michael Lefcoe, A.

Subsets More Likely To Benefit From Surgery Or Prophylactic Cranial Irradiation After Chemoradiation For Localized Non-Small-Cell Lung Cancer, Bruce Keith, Mark Vincent, Larry Stitt, Anna Tomiak, Richard Malthaner, Edward Yu, Pauline Truong, Richard Inculet, Michael Lefcoe, A. Dar, Walter Kocha, Ian Craig
Edward Yu
After chemoradiation for localized non-small-cell lung cancer, surgery and prophylactic cranial irradiation (PCI) have been used as additional therapies. Less than a third of patients develop brain recurrences, or have local recurrence as their sole initial site of recurrence; these are groups that would benefit from PCI or surgery, respectively. Pretreatment identification of patients more likely to benefit from surgery or PCI would be useful. A retrospective analysis of 80 patients was performed to determine prognostic factors for such patterns of failure. Twenty-nine patients were subsequently selected for surgery in a nonrandomized manner. Seventeen patients had isolated local initial recurrence …
The Existence Of Gender-Specific Promotion Standards In The U.S., Kathy Paulson Gjerde
The Existence Of Gender-Specific Promotion Standards In The U.S., Kathy Paulson Gjerde
Kathy A. Paulson Gjerde
This paper is motivated by the claim that promotion probabilities are lower for women than men. Using data from the 1984 and 1989 National Longitudinal Youth Surveys, this paper tests this claim and two related hypotheses concerning training and ability. It is found that females are less likely to be promoted than males, and females receive less training than males. The relationship between promotion and gender varies across occupations, however, suggesting that the alleged glass ceiling faced by women and other minorities in the workplace is not uniform across all labor markets.

Western Frontier Or Feudal Society? Metaphors And Perceptions Of Cyberspace, Alfred C. Yen
Western Frontier Or Feudal Society? Metaphors And Perceptions Of Cyberspace, Alfred C. Yen
Alfred C. Yen
The Article examines how metaphors influence perceptions of cyberspace. Among other things, the Article studies the comparison of cyberspace to the American western frontier and the metaphor's construction cyberspace as a "place" whose natural characteristics guarantee freedom and opportunity. This supports an often-made claim that cyberspace is different from real space, and that government should generally refrain from regulating the Internet.
The Article surveys the basis of the western frontier metaphor in academic history and popular culture and concludes that the metaphor misleads people to overestimate cyberspace's "natural" ability to guarantee freedom and opportunity. The Article accomplishes this in part …
A Convenient One-Pot, Organoaluminum Mediated Vinylsilane Synthesis From Non-Enolizable Ketones Via The Peterson Protocol, Man Lung Kwan, Merle Battiste
A Convenient One-Pot, Organoaluminum Mediated Vinylsilane Synthesis From Non-Enolizable Ketones Via The Peterson Protocol, Man Lung Kwan, Merle Battiste
Man Lung Desmond Kwan
Vinylsilanes serve as convenient vinyl anion equivalents which have gained popularity over decades. A variety of non-enolizable aromatic ketones are converted to the corresponding vinylsilanes in a one-pot procedure involving the addition of (trimethylsilylmethyl)lithium to aromatic ketones followed by addition of diethylaluminum chloride and then small amounts of water. Halide and alkoxide substituents are tolerated, and this trans-stereoselective (broad generalization; the most sterically bulky group on the double bond is trans to the trimethylsilyl group) reaction affords vinylsilanes in good yield.

Syd-1, A Presynaptic Protein With Pdz, C2 And Rhogap-Like Domains, Specifies Axon Identity In C. Elegans, Steven Hallam, Alexandr Goncharov, Jason Mcewen, Renee Baran, Yishi Jin
Renee Baran
Axons are defined by the presence of presynaptic specializations at specific locations. We show here that loss-of-function mutations in the C. elegans gene syd-1 cause presynaptic specializations to form in the dendritic processes of GABA-expressing motor neurons during initial differentiation. At a later developmental stage, however, syd-1 is not required for the polarity respecification of a subset of these neurons. The SYD-1 protein contains PDZ, C2 and rho–GTPase activating protein (GAP)-like domains, and is localized to presynaptic terminals in mature neurons. A truncated SYD-1 that lacks the rhoGAP domain interferes with neurite outgrowth and guidance. Our data indicate that syd-1 …

Hard Code Now!, Ugo Mattei
Ugo Mattei
This paper advocates the immediate beginning of a genuine, pluralistic political process leading to a binding codification of European Private Law. It is a critique of what I characterize as the post-modernist "soft" discourse of current European private law. This soft ideology stays behind proposals of "restatement" of European law; notions of "model" European codes; assertions of the sufficiency of European legal science as an alternative to codification; theories of competition between national legal systems as an efficient pattern of private law integration; notions of facilitating, optional "default law" as an efficient alternative to mandatory binding legal rules. My claim …
Asymptotic Solitons For A Higher-Order Modified Korteweg–De Vries Equation, T. Marchant
Asymptotic Solitons For A Higher-Order Modified Korteweg–De Vries Equation, T. Marchant
Tim Marchant
Solitary wave interaction for a higher-order modified Korteweg–de Vries (mKdV) equation is examined. The higher-order mKdV equation can be asymptotically transformed to the mKdV equation, if the higher-order coefficients satisfy a certain algebraic relationship. The transformation is used to derive the higher-order two-soliton solution and it is shown that the interaction is asymptotically elastic. Moreover, the higher-order phase shifts are derived using the asymptotic theory. Numerical simulations of the interaction of two higher-order solitary waves are also performed. Two examples are considered, one satisfies the algebraic relationship derived from the asymptotic theory, and the other does not. For the example …
An Evaluation Of College And Low Income Youth Writing Together: Self Discovery And Cultural Connection, Genevieve Chandler
An Evaluation Of College And Low Income Youth Writing Together: Self Discovery And Cultural Connection, Genevieve Chandler
Genevieve E. Chandler
Although the health and healing effects of writing have been documented in the literature, most of the studies have focused primarily on individuals writing alone. This formative evaluation is a component of an intervention reported elsewhere. The evaluation describes the experience of low-income youth and college students ( n = 7) writing in a group during a 10-week workshop. The results revealed the development of protective processes of self-esteem, self-efficacy, coping strategies, social support, and cultural connections. In the weekly 2-hr writing sessions, using the Amherst Writers and Artists method, participants were encouraged to write their stories in their own …

Ultrafast Measurement Of Two-Photon Absorption By Loss Modulation, Peifang Tian, Warren Warren
Peifang Tian
We demonstrate a direct and sensitive technique for measuring two-photon absorption (TPA).An intensity- modulated femtosecond laser beam passes through a sample exhibiting TPA.A TPA signal at twice the modulation frequency is then generated and subsequently measured by a lock-in amplifier. The absolute TPA cross section of Rhodamine 6G at 800nm is found to be 15.32.010 -50 cm 4 s / photon and agrees well with previously published results obtained with much higher intensity [J.Chem.Phys. 112, 9201 (2000)]. Our method may be especially useful in measuring nonlinear absorptions of nonfluorescent materials.

Infrared Depletion Spectroscopy Of Aniline-Acetonitrile Cation And Aniline-Acetonitrile-Water Cation Clusters, H. Nagai, Naveed Piracha, T. Nakanaga
Naveed K. Piracha
The vibrational spectra of the aniline-acetonitrile^+ and the aniline-acetonitrile-water^+ cluster cations have been measured by the infrared depletion spectroscopy in the frequency region of NH and OH stretching vibrations. One absorption band was observed at 3437cm^-^1 in the infrared spectrum of the aniline-acetonitrile^+ cluster cation, and was assigned to the NH stretching vibration of free NH of aniline. As for the aniline-water-acetonitrile^+ cluster cation, three absorptions were observed at 3722, 3634 and 3247cm^-^1, which were assigned to the anti-symmetric stretching and symmetric stretching vibrations of OH of water and the stretching vibrations of NH bond interacting with water, respectively. In …

Electrical Conductivity And Thermopower Of Cu–Sio[Sub 2] Nanogranular Films., W. Chen, J. Lin, X. Zhang, H. Shin, Jeffrey Dyck, C. Uher
Jeffrey Dyck
We have measured the thermopower S and electrical conductivity σ in a series of Cu[sub x](SiO[sub 2])[sub 1-x] nanogranular films between 2 and 300 K with Cu volume fraction x varying from 0.43 up to 1.0. At low temperatures, disorder-enhanced electron-electron interaction effects dictate the behavior of σ. A crossover of the temperature dependence from σ∝ √T to σ∝ T[sup 1/3] is observed as x is lowered and the metal-insulator transition is approached. S is small, shows linear temperature dependence, and is rather insensitive to the change of x. Effects of annealing are also discussed.

Characterizing Gene Expression During Lens Formation In Xenopus Laevis: Evaluating The Model For Embryonic Lens Induction, Brian Walter, Jonathan Henry, Maria Carinato, Jonathan Schaefer, Adam Wolfe, Brian Walter, Kimberly Perry, Tricia Elbl
Brian Walter
Few directed searches have been undertaken to identify the genes involved in vertebrate lens formation. In the frog Xenopus, the larval cornea can undergo a process of transdifferentiation to form a new lens once the original lens is removed. Based on preliminary evidence, we have shown that this process shares many elements of a common molecular/genetic pathway to that involved in embryonic lens development. A subtracted cDNA library, enriched for genes expressed during cornea-lens transdifferentiation, was prepared. The similarities/identities of specific clones isolated from the subtracted cDNA library define an expression profile of cells undergoing cornea-lens transdifferentiation ("lens regeneration") and …

Lessons From Everyday Lives: A Moral Justification For Acute Care Research, Andrew Mcrae, Charles Weijer
Charles Weijer
Progress in emergency and critical care requires that clinical research be performed on patients who are incapable of granting consent for research participation. Analyses of the ethics of such research have left some questions incompletely answered. Why should we be permitted to expose vulnerable patients to research risks without their consent? In particular, how do we justify research interventions that have no potential benefit for participants (nontherapeutic interventions)? This article presents a moral justification for nontherapeutic interventions in emergency research. By relying on a framework for assessing research risks, and by drawing on the example of pediatric research, this justification …
