Objections to Disclosure Settlements: A How-To Guide
Stockholder litigation remains in crisis, with over seventy percent of major mergers and acquisitions subject to litigation. A contributing factor is the breakdown of the adversary process at settlement, when former opponents join hands in favor of a compromise that too often expends corporate resources for no real recovery to the plaintiff class. One obvious corrective is the shareholder’s objection to settlement, which restores adversarial character to the settlement process. Shareholders, however, face substantial difficulties in making such objections. In this article, the authors detail the problem and share their experiences in addressing these obstacles, providing a how-to manual for future shareholder objections to class action settlements in merger litigation
Field-theory calculation of the electric dipole moment of the neutron and paramagnetic atoms
Electric dipole moments (edms) of bound states that arise from the
constituents having edms are studied with field-theoretic techniques. The
systems treated are the neutron and a set of paramagnetic atoms. In the latter
case it is well known that the atomic edm differs greatly from the electron edm
when the internal electric fields of the atom are taken into account. In the
nonrelativistic limit these fields lead to a complete suppression, but for
heavy atoms large enhancement factors are present. A general bound-state field
theory approach applicable to both the neutron and paramagnetic atoms is set
up. It is applied first to the neutron, treating the quarks as moving freely in
a confining spherical well. It is shown that the effect of internal electric
fields is small in this case. The atomic problem is then revisited using
field-theory techniques in place of the usual Hamiltonian methods, and the
atomic enhancement factor is shown to be consistent with previous calculations.
Possible application of bound-state techniques to other sources of the neutron
edm is discussed.Comment: 21 pages, 5 figure
Kondo resonance line-shape of magnetic adatoms on decoupling layers
The zero-bias resonance in the dI/dV tunneling spectrum recorded using a
scanning tunneling microscope above a spin-1/2 magnetic adatom (such as Ti)
adsorbed on a decoupling layer on metal surface can be accurately fitted using
the universal spectral function of the Kondo impurity model both at zero field
and at finite external magnetic field. Excellent agreement is found both for
the asymptotic low-energy part and for the high-energy logarithmic tails of the
Kondo resonance. For finite magnetic field, the nonlinear fitting procedure
consists in repeatedly solving the impurity model for different Zeeman energies
in order to obtain accurate spectral functions which are compared with the
experimental dI/dV curves. The experimental results at zero field are
sufficiently restraining to enable an unprecedented reliability in the
determination of the Kondo temperature, while at finite fields the results are
more ambiguous and two different interpretations are proposed
Knowledge Resources, Exploration, and Exploitation: A New Perspective on the Interplay Between Innovation and Application
Knowledge resources are the fundamental ingredients used in exploration and exploitation and an overlooked source of distinction and tension between these two processes. In this paper we use a strategic lens to differentiate evidence-based knowledge resources from tinkerable knowledge resources. This conceptualization provides the basis for a bridge between the literature on the resource-based view of the firm and research into exploration and exploitation. We suggest that an examination of knowledge resources offers a new perspective for understanding exploration and exploitation, and suggests new opportunities for achieving organizational ambidexterity. A proposed model indicates the application consequences of match and mismatch across knowledge resources and knowledge flow activities in terms of exploration and exploitation. An agenda for future research is proposed along with steps that managers can take to develop exploration and exploitation capabilities in their firms by managing their knowledge resources more precisely and effectively.knowledge resources, exploration, exploitation, knowledge management
Biomass and reproduction of Pacific sardine (Sardinops sagax) off the Pacific northwestern United States, 2003–2005
The Pacific sardine (Sardinops sagax) is distributed along the west coast of North America from Baja California to British Columbia. This article presents estimates of biomass, spawning biomass, and related biological parameters based on four trawl-ichthyoplankton surveys conducted during July 2003 –March 2005 off Oregon and Washington. The trawl-based biomass estimates, serving as
relative abundance, were 198,600 t (coefficient of variation [CV] = 0.51) in July 2003, 20,100 t (0.8) in March
2004, 77,900 t (0.34) in July 2004, and 30,100 t (0.72) in March 2005 over an area close to 200,000 km2. The biomass estimates, high in July and low in March, are a strong indication of migration in and out of this area. Sardine spawn in July off the Pacific Northwest (PNW) coast and
none of the sampled fish had spawned in March. The estimated spawning biomass for July 2003 and July 2004 was 39,184 t (0.57) and 84,120 t (0.93), respectively. The average active female sardine in the PNW spawned every 20–40 days compared to every 6–8 days off California. The spawning habitat was located in the southeastern area off the PNW coast, a shift from the northwest area off the PNW
coast in the 1990s. Egg production in off the PNW for 2003–04 was lower than that off California and that in the 1990s. Because the biomass of Pacific sardine off the PNW appears to be supported heavily by migratory fish from California, the sustainability of the local PNW population relies on the stability of the population off California, and on local oceanographic conditions for local residence
Ion-beam-enhanced adhesion in the electronic stopping region
The use of ion beams in the electronic stopping region to improve the adhesion of insulators to other materials is described. In particular, the bonding of Au films to Teflon, ferrite, and SiO2 was improved by bombarding them with He and Cl, respectively. Improvements in bonding were also observed for Au on glass, Au and Cu on sapphire, and Si3N4 on Si. The mechanism is apparently associated with sputtering and track forming processes occurring in the electronic stopping region. Some applications are discussed
New devices for flow measurements: Hot film and burial wire sensors, infrared imagery, liquid crystal, and piezo-electric model
An experimental program aimed at identifying areas in low speed aerodynamic research where infrared imaging systems can make significant contributions is discussed. Implementing a new technique, a long electrically heated wire was placed across a laminar flow. By measuring the temperature distribution along the wire with the IR imaging camera, the flow behavior was identified
