The Interpersonal Circumplex and the Five-Factor Theory of personality as frames of reference
This article reviews existing approaches to defining and distinguishing
communication styles and proposes a common frame of reference for future
research. The literature review yields two schools of thought: the behavior-
centered perspective and the personality-oriented perspective. Although these
lines of research differ in their ways of defining communication styles, they
show considerable similarities with respect to their classification. Many
researchers build their taxonomies on two key dimensions: assertiveness and
responsiveness. We propose embedding communication styles into the Five-Factor
Theory (FFT) and defining them as characteristic adaptations of personality.
We also suggest the Interpersonal Circumplex (IPC) as a reference model for
distinguishing communication styles as it is able to integrate substantial
dimensions and facets of existing taxonomies in a parsimonious way
The Distribution of Amphipods in Southeastern Minnesota and Their Relation to Water Quality and Land Use
The distribution of the amphipods Gammarus pseudolimnaeus and Hyalella azteca was determined from 97 designated trout streams in Minnesota, along with temperature, conductivity, and nitrate levels. Streams were classified into 4 land use/geology groups. G. pseudolimnaeus was found in 11 counties and at 123 of 168 sites in 83 of the 97 streams sampled. Hyalella azteca was found in 7 counties at 26 sites m 21 streams. Spearman rank correlations showed a high degree of correlation between nitrate (range: 0-11 mg N/L), conductivity (range: 325-870 ÎĽS/cm), and geology. The relative abundance of G. pseudolimnaeus was negatively correlated with nitrate, geology groups, and H. azteca relative abundance; G. pseudolimnaeus was most common in low-order streams originating from diffuse springs, and H. Azteca was more common in larger streams. The distribution of G. pseudolimnaeus with its strong correlation to geology may be largely influenced by land use and it may be a good long-term indicator of water quality
Logarithmic conformal field theories and AdS correspondence
We generalize the Maldacena correspondence to the logarithmic conformal field
theories. We study the correspondence between field theories in
(d+1)-dimensional AdS space and the d-dimensional logarithmic conformal field
theories in the boundary of . Using this correspondence, we get the
n-point functions of the corresponding logarithmic conformal field theory in
d-dimensions.Comment: 10 pages, LaTeX. A paragraph was added. To appear in Int. J. Mod.

Using the Red Clover Polyphenol Oxidase Gene to Inhibit Proteolytic Activity in Lucerne
Preserving high quality forage in cool humid regions of agricultural production remains a challenge due to potentially high levels of protein degradation during ensiling. Red clover is an exception maintaining its high protein levels during ensiling. Decreased proteolytic activity in red clover is due to polyphenol oxidase (PPO) activity and appropriate o-diphenol substrates (Jones et al., 1995, Sullivan et al., 2004). This work highlights potential strategies for utilising PPO as a means of decreasing proteolytic degradation during the ensiling of lucerne and other forages
Correlation Functions and AdS/LCFT Correspondence
Correlation functions of Logarithmic conformal field theory is investigated
using the ADS/CFT correspondence and a novel method based on nilpotent weights
and 'super fields'. Adding an specific form of interaction, we introduce a
perturbative method to calculate the correlation functions.Comment: 11 pages, 4 figure
Gravitino Propagator in anti de Sitter space
We construct the gauge invariant part of the propagator for the massless
gravitino in AdS(d+1) by coupling it to a conserved current. We also derive the
propagator for the massive gravitino.Comment: 24 pages; LaTe
Quarkonium from the Fifth Dimension
Adding fundamental matter of mass m_Q to N=4 Yang Mills theory, we study
quarkonium, and "generalized quarkonium" containing light adjoint particles. At
large 't Hooft coupling the states of spin<=1 are anomalously light (Kruczenski
et al., hep-th/0304032). We examine their form factors, and show these hadrons
are unlike any known in QCD. By a traditional yardstick they appear infinite in
size (as with strings in flat space) but we show that this is a failure of the
yardstick. All of the hadrons are actually of finite size ~ \sqrt{g^2N}/m_Q,
regardless of their radial excitation level and of how many valence adjoint
particles they contain. Certain form factors for spin-1 quarkonia vanish in the
large-g^2N limit; thus these hadrons resemble neither the observed J/Psi
quarkonium states nor rho mesons.Comment: 57 pages, LaTeX, 5 figure
Holographic Normal Ordering and Multi-particle States in the AdS/CFT Correspondence
The general correlator of composite operators of N=4 supersymmetric gauge
field theory is divergent. We introduce a means for renormalizing these
correlators by adding a boundary theory on the AdS space correcting for the
divergences. Such renormalizations are not equivalent to the standard normal
ordering of current algebras in two dimensions. The correlators contain contact
terms that contribute to the OPE; we relate them diagrammatically to
correlation functions of compound composite operators dual to multi-particle
states.Comment: 18 pages, one equation corr., further comments and refs. adde
New Results on Holographic Three-Point Functions
We exploit a gauge invariant approach for the analysis of the equations
governing the dynamics of active scalar fluctuations coupled to the
fluctuations of the metric along holographic RG flows. In the present approach,
a second order ODE for the active scalar emerges rather simply and makes it
possible to use the Green's function method to deal with (quadratic)
interaction terms. We thus fill a gap for active scalar operators, whose
three-point functions have been inaccessible so far, and derive a general,
explicitly Bose symmetric formula thereof. As an application we compute the
relevant three-point function along the GPPZ flow and extract the irreducible
trilinear couplings of the corresponding superglueballs by amputating the
external legs on-shell.Comment: v2: reference added, typos corrected v3: sign convention for
background changed, agrees with version published in JHE
