“The Management of Creativity”, Managing the Creative Mind: A Business Elective
The immediate problem facing the authors was replacing someone with the background and stature of Joseph Abboud with an individual or, as it eventually worked out, four individuals with differing creative backgrounds and levels of success that would be of benefit to the students (in the spring 2006 semester the course was offered to undergraduate business students) enrolled in the course. Replacing Abboud proved to be not as difficult as the authors originally imagined. Within a period of three weeks, four individuals with diverse backgrounds in film, music, sports entertainment, and entrepreneurship were identified and agreed to take part in the newly redesigned course. In hindsight, these individuals created a dynamic new learning environment for the students enrolled in this course, one they could not have benefited from previously. It should be kept in mind that the purpose of the class was, and continues to be, to offer business students the opportunity to hear from successful individuals from various creative disciplines and to offer students opportunities to hear of the challenges they faced and continue to face with regard to financing and marketing their respective businesses and careers. It is not unusual for individuals with creative backgrounds to have little or any experience or knowledge of the challenges with regard to financing and marketing their ideas. This, once again, was the onus for the development and continuation of this class

Foundation Treatments Using Sand Compaction Piles and Surcharge Loading Marine Corps Air Station Iwakuni, Japan, A Case Study
Two, 42-meter diameter, 12.2 meter high (100,000 barrel) above ground jet fuel tanks are currently under construction by the Japan Engineering District (JED), U.S. Army Corps of Engineers for the Defense Logistic Agency (DLA) at Marine Corps Air Station (MCAS) Iwakuni. This presentation is a case study of the installation of Sand Compaction Piles (SCP’s) and surcharge at MCAS Iwakuni. The geology below the tanks consists of poorly behaving liquefiable silty clays that can affect the bearing capacity of the loaded tanks. The site was formerly a marsh area filled with various debris and construction refuse and then covered with fill material. The elevation of the original marsh area is at sea level, and corresponds to the elevation of groundwater. The near surface soil consists of 6 to 12 meters of loose, liquefiable sand. Underlying this sand layer is 15 to 20 meters of soft, compressible clays and silts. A medium to dense sand and gravel underlies the soft clays and silts. The Iwakuni Faults, which are active faults, are located near MCAS Iwakuni. These faults are classified as Class B under the Japanese Standard, which is medium level in magnitude. The distance from MCAS Iwakuni to these faults is approximately 8 km. Foundation treatments to include SCP’s, Sand Drainage Piles (SDPs) and surcharge mounds are used to improve foundation conditions. SCPs are not a deep foundation as in a typical pile, but rather a method for dynamically densifying loose sands. They have used extensively in Japan for many years to decrease the potential for liquefaction damage. Effectiveness of the SCPs in densifying the surrounding soils is determined by measuring the “N” value determined from a Standard Penetration Test taken in the area between the SCPs. The clay layer was consolidated using a soil surcharge. Percent consolidation was determined using vibrating wire piezometers
The rotational modes of relativistic stars: Numerical results
We study the inertial modes of slowly rotating, fully relativistic compact
stars. The equations that govern perturbations of both barotropic and
non-barotropic models are discussed, but we present numerical results only for
the barotropic case. For barotropic stars all inertial modes are a hybrid
mixture of axial and polar perturbations. We use a spectral method to solve for
such modes of various polytropic models. Our main attention is on modes that
can be driven unstable by the emission of gravitational waves. Hence, we
calculate the gravitational-wave growth timescale for these unstable modes and
compare the results to previous estimates obtained in Newtonian gravity (i.e.
using post-Newtonian radiation formulas). We find that the inertial modes are
slightly stabilized by relativistic effects, but that previous conclusions
concerning eg. the unstable r-modes remain essentially unaltered when the
problem is studied in full general relativity.Comment: RevTeX, 29 pages, 31 eps figure
Small Polarons in Transition Metal Oxides
The formation of polarons is a pervasive phenomenon in transition metal oxide
compounds, with a strong impact on the physical properties and functionalities
of the hosting materials. In its original formulation the polaron problem
considers a single charge carrier in a polar crystal interacting with its
surrounding lattice. Depending on the spatial extension of the polaron
quasiparticle, originating from the coupling between the excess charge and the
phonon field, one speaks of small or large polarons. This chapter discusses the
modeling of small polarons in real materials, with a particular focus on the
archetypal polaron material TiO2. After an introductory part, surveying the
fundamental theoretical and experimental aspects of the physics of polarons,
the chapter examines how to model small polarons using first principles schemes
in order to predict, understand and interpret a variety of polaron properties
in bulk phases and surfaces. Following the spirit of this handbook, different
types of computational procedures and prescriptions are presented with specific
instructions on the setup required to model polaron effects.Comment: 36 pages, 12 figure
Negative impacts of invasive predators used as biological control agents against the pest snail Lissachatina fulica: the snail Euglandina ‘rosea’ and the flatworm Platydemus manokwari
Since 1955 snails of the Euglandina rosea
species complex and Platydemus manokwari flatworms were widely introduced in attempted biological
control of giant African snails (Lissachatina fulica)
but have been implicated in the mass extinction of
Pacific island snails. We review the histories of the 60
introductions and their impacts on L. fulica and native
snails. Since 1993 there have been unofficial releases
of Euglandina within island groups. Only three official
P. manokwari releases took place, but new populations
are being recorded at an increasing rate, probably
because of accidental introduction. Claims that these
predators controlled L. fulica cannot be substantiated;
in some cases pest snail declines coincided with
predator arrival but concomitant declines occurred
elsewhere in the absence of the predator and the
declines in some cases were only temporary. In the
Hawaiian Islands, although there had been some earlier declines of native snails, the Euglandina
impacts on native snails are clear with rapid decline
of many endemic Hawaiian Achatinellinae following
predator arrival. In the Society Islands, Partulidae tree
snail populations remained stable until Euglandina
introduction, when declines were extremely rapid with
an exact correspondence between predator arrival and
tree snail decline. Platydemus manokwari invasion
coincides with native snail declines on some islands,
notably the Ogasawara Islands of Japan, and its
invasion of Florida has led to mass mortality of
Liguus spp. tree snails. We conclude that Euglandina
and P. manokwari are not effective biocontrol agents,
but do have major negative effects on native snail
faunas. These predatory snails and flatworms are
generalist predators and as such are not suitable for
biological control
Whispering gallery modes in photoluminescence and Raman spectra of a spherical microcavity with CdTe quantum dots: anti-Stokes emission and interference effects
We have studied the photoluminescence and Raman spectra of a system consisting of a polystyrene latex microsphere coated by CdTe colloidal quantum dots. The cavity-induced enhancement of the Raman scattering allows the observation of Raman spectra from only a monolayer of CdTe quantum dots. Periodic structure with very narrow peaks in the photoluminescence spectra of a single microsphere was detected both in the Stokes and anti-Stokes spectral regions, arising from the coupling between the emission of quantum dots and spherical cavity modes
