Fundamentals, Market Timing, and Seasoned Equity Offerings

Firms conduct SEOs to resolve a near-term liquidity squeeze, and not primarily to exploit market timing opportunities. Without the SEO proceeds, 62.6% of issuers would have insufficient cash to implement their chosen operating and non-SEO financing decisions the year after the SEO. Although the SEO decision is positively related to a firm's market-to-book (M/B) ratio and prior excess stock return and negatively related to its future excess return, these relations are economically immaterial. For example, a 150% swing in future net of market stock returns (from a 75% gain to a 75% loss over three years) increases by only 1% the probability of an SEO in the immediately prior year. Strikingly, most firms with quintessential "market timer" characteristics fail to issue stock and a non-trivial number of mature firms do issue stock, with current and former dividend payers raising more than half of all issue proceeds.

Tree Shadow Series

My shadow paintings aim to create a symbiotic relationship between contemporary art and nature by combining synthetically produced materials with distinct organic forms. In every moment, there exist uncontrollable variables which create unique experiences. I am in awe of the elegant audacity with which nature reveals these moments. I initiate a discussion with nature by bringing the canvas outside and painting fleeting shadows projected onto the canvas. Although my first four paintings stopped here, the more recent paintings were then brought into the studio, where it was my challenge to formally transform the layered tracings into paintings. Ideally, these captured moments of light (or the absence thereof) accumulate to yield another completely individual experience provided by the color and movement of the painting itself

A Psychological and Behavioral Analysis of Child Sex Offenders: the Use of Expert Search Warrants in the Criminal Investigation of Acquaintance Molestation: the Use of Expert Search Warrants in the Criminal Investigation of Acquaintance Molestation

The Use of Expert Search Warrants in the Criminal Investigation of Acquaintance Molestation Child sexual abuse is a critical social problem throughout the U.S. and the world. Often, a competent and thorough investigation can substantiate or discredit an allegation and notably support a subsequent prosecution of a substantiated case. A manual was created to assist law enforcement detectives who investigate allegations of child sex abuse. The investigative process includes: (a) forensic interviews of child victims, (b) collection of corroborative evidence, (c) analysis of offender characteristics and typologies, (d) offender interviews, and (e) search warrants to include expert search warrants

8. The 1980s

From the Introduction, “The Changes at ILR that began in the seventies slipped imperceptibly into the eighties, and those that may have originated at that time have, for better or worse, left their mark on the present decade. In other words, dividing history into decades is not a particularly precise way of delineating times. Clearly, there was much gaiety preceding and following the Gay Nineties, as there were certainly many roars heard before and after the Roaring Twenties. Moreover, since the speed of change in academia runs at such a leisurely pace, it is virtually impossible to say exactly when an idea found its way into formal practice. Includes: Introduction; A Dean’s View, 1980-85; Deaning, 1985-88; Robert Risley; and An Advisory Council Perspective

Light Assisted Collisional Loss in a 85/87^{85/87}Rb Ultracold Optical Trap

We have studied hetero- and homonuclear excited state/ground state collisions by loading both $^{85}$Rb and $^{87}$Rb into a far off resonant trap (FORT). Because of the relatively weak confinement of the FORT, we expect the hyperfine structure of the different isotopes to play a crucial role in the collision rates. This dependence on hyperfine structure allows us to measure collisions associated with long range interatomic potentials of different structure: such as long and short ranged; or such as purely attractive, purely repulsive, or mixed attractive and repulsive. We observe significantly different loss rates for different excited state potentials. Additionally, we observe that some collisional channels' loss rates are saturated at our operating intensities (~15 mW/cm$^{2}$). These losses are important limitations in loading dual isotope optical traps.Comment: about 8 pages, 5 figure

Preferentially Etched Epitaxial Liftoff of InP Material

The present invention is directed toward a method of removing epitaxial substrates from host substrates. A sacrificial release layer of ternary material is placed on the substrate. A layer of InP is then placed on the ternary material. Afterward a layer of wax is applied to the InP layer to apply compressive force and an etchant material is used to remove the sacrificial release layer

Peeled film GaAs solar cells for space power

Gallium arsenide (GaAs) peeled film solar cells were fabricated, by Organo-Metallic Vapor Phase Epitaxy (OMVPE), incorporating an aluminum arsenide (AlAs) parting layer between the device structure and the GaAs substrate. This layer was selectively removed by etching in dilute hydrofloric (HF) acid to release the epitaxial film. Test devices exhibit high series resistance due to insufficient back contact area. A new design is presented which uses a coverglass superstrate for structural support and incorporates a coplanar back contact design. Devices based on this design should have a specific power approaching 700 W/Kg

SYK Regulates mTOR Signaling in AML

Spleen Tyrosine Kinase (SYK) was recently identified as a new target in acute myeloid leukemia (AML); however, its mechanistic role in this disease is poorly understood. Based on the known interaction between SYK and mTOR signaling in lymphoma, we hypothesized that SYK may regulate mTOR signaling in AML. Both small-molecule inhibition of SYK and SYK-directed shRNA suppressed mTOR and its downstream signaling effectors, as well as its upstream activator, AKT. Moreover, the inhibition of multiple nodes of the PI3K signaling pathway enhanced the effects of SYK suppression on AML cell viability and differentiation. Evaluation of the collateral MAPK pathway revealed a heterogeneous response to SYK inhibition in AML with down-regulation of MEK and ERK phosphorylation in some AML cell lines but a paradoxical increase in MEK/ERK phosphorylation in RAS-mutated AML. These studies reveal SYK as a regulator of mTOR and MAPK signaling in AML and demonstrate that inhibition of PI3K pathway activity enhances the effects of SYK inhibition on AML cell viability and differentiation
