Aquaculture and markets: a research agenda
This issues brief proposes an agenda for markets and trade research that supports pro-poor development of aquaculture. It summarises key trends and issues relating to global aquaculture development and identifies critical markets and trade dimensions. Coinciding with renewed interest and change in global agricultural research, this brief is targeted to aquaculture development practitioners and researchers. It aims to provoke discussion on the key areas of markets-related analysis needed to ensure that aquaculture research delivers the strongest poverty reduction and food security outcomes. This focus means that the paper inevitably covers both markets and trade related research and identifies some critical gaps in the foundational poverty analysis.Aquaculture, Trade, Research, Market Research
Fire Retardancy in 2001
Fire is a world-wide problem which claims lives and causes significant loss of property. Some of the problems are discussed and the solution delineated. This peer-reviewed volume is designed to be as the state-of-the-art. This chapter provides a perspective for current work
Effective Employee Incentive Plans: Features and Implementation Processes
[Excerpt] This paper will evaluate the effectiveness of broad-based employee incentives, identifying the features of effective plans. For our purposes, “broad-based” is used to signal that more than 50 percent of employees are eligible for this variable pay plan. In addition, the terms “variable pay plan” and “pay for performance” are used interchangeably as they appeared in the original sources
Approximate Next-to-Leading Order and Next-to-Next-to-Leading Order Corrections
For processes involving structure functions and/or fragmentation functions,
arguments that, over a range of a proper kinematic variable, there is a part
that dominates the next-to-leading order (NLO) corrections are briefly
reviewed. The arguments are tested against more recent NLO and in particular
complete next-to-next-to-leading order (NNLO) calculations. A critical
examination of when these arguments may not be useful is also presented.Comment: 8 pages and 4 figure

Development of an Advanced Force Field for Water using Variational Energy Decomposition Analysis
Given the piecewise approach to modeling intermolecular interactions for
force fields, they can be difficult to parameterize since they are fit to data
like total energies that only indirectly connect to their separable functional
forms. Furthermore, by neglecting certain types of molecular interactions such
as charge penetration and charge transfer, most classical force fields must
rely on, but do not always demonstrate, how cancellation of errors occurs among
the remaining molecular interactions accounted for such as exchange repulsion,
electrostatics, and polarization. In this work we present the first generation
of the (many-body) MB-UCB force field that explicitly accounts for the
decomposed molecular interactions commensurate with a variational energy
decomposition analysis, including charge transfer, with force field design
choices that reduce the computational expense of the MB-UCB potential while
remaining accurate. We optimize parameters using only single water molecule and
water cluster data up through pentamers, with no fitting to condensed phase
data, and we demonstrate that high accuracy is maintained when the force field
is subsequently validated against conformational energies of larger water
cluster data sets, radial distribution functions of the liquid phase, and the
temperature dependence of thermodynamic and transport water properties. We
conclude that MB-UCB is comparable in performance to MB-Pol, but is less
expensive and more transferable by eliminating the need to represent
short-ranged interactions through large parameter fits to high order

Superpartners at LHC and Future Colliders: Predictions from Constrained Compactified M-Theory
We study a realistic top-down M-theory compactification with low-scale
effective Supersymmetry, consistent with phenomenological constraints. A
combination of top-down and generic phenomenological constraints fix the
spectrum. The gluino mass is predicted to be about 1.5 TeV. Three and only
three superpartner channels, , and
(where are Wino-like), are expected
to be observable at LHC-14. We also investigate the prospects of finding heavy
squarks and Higgsinos at future colliders. Gluino-stop-top,
gluino-sbottom-bottom associated production and first generation squark
associated production should be observable at a 100 TeV collider, along with
direct production of heavy Higgsinos. Within this framework the discovery of a
single sparticle is sufficient to determine uniquely the SUSY spectrum,
yielding a number of concrete testable predictions for LHC-14 and future
colliders, and determination of and thereby other fundamental
quantities.Comment: 19 pages, 4 figure
Tyrosinase and phenolic pressor amines
Basic to the consideration of the action of tyrosinase on the oxidation of phenolic pressor amines are the observations of Keilin and Mann (16) and of Nelson and his coworkers (17-19) that show that different preparations may vary considerably in their relative actions on monophenols and o-diphenols. Both of these types of activity appear to belong to the same enzyme complex, as they bear a proportionality to the same copper content. However, since the activities vary with the purity and method of purification, each enzyme preparation must be defined in terms of both monophenolase and o-diphenolase activities. This was done in the present studies, and modifications of previously described preparative methods were required to retain a reasonable proportioning of such activities in purified preparations
