Customer segmentation using unobserved heterogeneity in the perceived value-loyalty-intentions link

Multiple facets of perceived value perceptions drive loyalty intentions. However, this\ud
value-loyalty link is not uniform for all customers. In fact, the present study identifies three\ud
different segments that are internally consistent and stable across different service industries,\ud
using two data sets: the wireless telecommunication industry (sample size 1,122) and the\ud
financial services industry (sample size 982). Comparing the results of a single-class solution\ud
with finite mixture results confirms the existence of unobserved customer segments. The three\ud
segments found are characterized as "rationalists", "functionalists" and "value maximizers".\ud
These results point the way for value-based segmentation in loyalty initiatives and reflect the\ud
importance of a multidimensional conceptualization of perceived value, comprising cognitive\ud
and affective components. The present results substantiate the fact that assuming a\ud
homogeneous value-loyalty link provides a misleading view of the market. The paper derives\ud
implications for marketing research and practice in terms of segmentation, positioning, loyalty\ud
programs and strategic alliances. (authors' abstract
Search for a heavy bottom-like quark in pp collisions at √s = 7 TeV

A search for pair-produced bottom-like quarks in pp collisions at sqrt(s) = 7 TeV is conducted with the CMS experiment at the LHC. The decay b' to tW is considered in this search. The b' b'-bar to tW^- t-bar W^+ process can be identified by the distinctive signature of trileptons and same-sign dileptons. With a data sample corresponding to an integrated luminosity of 34 inverse picobarns, no excess above the standard model background predictions is observed and a b' quark with a mass between 255 and 361 GeV/c^2 is excluded at the 95% confidence level
Measurement of the ratio of the 3-jet to 2-jet cross sections in pp collisions at √s = 7 TeV

A measurement of the ratio of the inclusive 3-jet to 2-jet cross sections as a function of the total jet transverse momentum, HT, in the range 0.2<HT<2.5 TeV is presented. The data have been collected at a proton–proton centre-of-mass energy of 7 TeV with the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb−1. Comparisons are made between the data and the predictions of different QCD-based Monte Carlo models for multijet production. All models considered in this study are consistent with the data for HT>0.5 TeV. This measurement extends to an HT range that has not been explored before
Biogeochemical and contaminant cycling in sediments from a human-impacted coastal lagoon – Introduction and summary

From 2001 to 2003, the Microbent project (‘‘Biogeochemical processes at the water sediment interface in eutrophic environment’’) was carried out within the framework of the Programme National Environnement Coˆtier, the French contribution to LandeOcean Interaction in the Coastal Zone (LOICZ). The Microbent programme was focused on the study of\ud
sediment biogeochemical cycles of carbon, oxygen, sulphur, iron, nitrogen, and phosphorus in relation to the faunal activity in the sediment and their relation with the mobility of metallic contaminants at the sedimentewater interface (SWI) in a Mediterranean coastal lagoon (Thau lagoon, France; Fig. 1). The aim of Microbent was to set up an interdisciplinary study bringing together geochemists, sedimentologists, and biologists in order to understand and quantify the main reaction pathways, and the fluxes of contaminants at the SWI, including those related to benthic fauna. Work was focused on the processes which generate contaminant fluxes: (1) early diagenetic processes, which generate the chemical conditions of the environment; (2) processes leading to the transfer of contaminants from particles toward biofilms, water column, and organisms; and (3) processes of sediment mixing by organisms and sediment accumulation
Intensification of the Amazon hydrological cycle over the last two decades

Reproduced with permission of the publisher. Online Open article. © 2013 American Geophysical UnionThe Amazon basin hosts half the planet's remaining moist tropical forests, but they may be threatened in a warming world. Nevertheless, climate model predictions vary from rapid drying to modest wetting. Here we report that the catchment of the world's largest river is experiencing a substantial wetting trend since approximately 1990. This intensification of the hydrological cycle is concentrated overwhelmingly in the wet season driving progressively greater differences in Amazon peak and minimum flows. The onset of the trend coincides with the onset of an upward trend in tropical Atlantic sea surface temperatures (SST). This positive longer-term correlation contrasts with the short-term, negative response of basin-wide precipitation to positive anomalies in tropical North Atlantic SST, which are driven by temporary shifts in the intertropical convergence zone position. We propose that the Amazon precipitation changes since 1990 are instead related to increasing atmospheric water vapor import from the warming tropical Atlantic
Reaction–Diffusion Finite Element Model of Lateral Line Primordium Migration to Explore Cell Leadership

Collective cell migration plays a fundamental role in many biological phenomena such as immune response, embryogenesis and tumorigenesis. In the present work, we propose a reaction–diffusion finite element model of the lateral line primordium migration in zebrafish. The population is modelled as a continuum with embedded discrete motile cells, which are assumed to be viscoelastic and able to undergo large deformations. The Wnt/ß-catenin–FGF and cxcr4b–cxcr7b signalling pathways inside the cohort regulating the migration are described through coupled reaction–diffusion equations. The coupling between mechanics and the molecular scenario occurs in two ways. Firstly, the intensity of the protrusion–contraction movement of the cells depends on the cxcr4b concentration. Secondly, the intra-synchronization between the active deformations and the adhesion forces inside each cell is triggered by the cxcr4b–cxcr7b polarity. This influences the inter-synchronization between the cells and results in two main modes of migration: uncoordinated and coordinated. The main objectives of the work were (i) to validate our assumptions with respect to the experimental observations and (ii) to decipher the mechanical conditions leading to efficient migration of the primordium. To achieve the second goal, we will specifically focus on the role of the leader cells and their position inside the population
The κ-(A)dS quantum algebra in (3+1) dimensions

The quantum duality principle is used to obtain explicitly the Poisson analogue of the κ-(A)dS quantum algebra in (3+1) dimensions as the corresponding Poisson–Lie structure on the dual solvable Lie group. The construction is fully performed in a kinematical basis and deformed Casimir functions are also explicitly obtained. The cosmological constant is included as a Poisson–Lie group contraction parameter, and the limit →0leads to the well-known κ-Poincaré algebra in the bicrossproduct basis. A twisted version with Drinfel’d double structure of this κ-(A)dS deformation is sketched.Ministerio de Economía y Competitividad (MINECO, Spain) under grant MTM2013-43820-P, and by Junta de Castilla y León (Spain) under grants BU278U14 and VA057U1
Biology and conservation of freshwater bivalves: past, present and future perspectives

Freshwater bivalves have been highly threatened by human activities, and recently their global decline has been causing conservational and social concern. In this paper, we review the most important research events in freshwater bivalve biology calling attention to the main scientific achievements. A great bias exists in the research effort, with much more information available for bivalve species belonging to the Unionida in comparison to other groups. The same is true for the origin of these studies, since the publishing pattern does not always correspond to the hotspots of biodiversity but is concentrated in the northern hemisphere mainly in North America, Europe and Russia, with regions such as Africa and Southeast Asia being quite understudied. We also summarize information about past, present and future perspectives concerning the most important research topics that include taxonomy, systematics, anatomy, physiology, ecology and conservation of freshwater bivalves. Finally, we introduce the articles published in this Hydrobiologia special issue related with the International Meeting on Biology and Conservation of Freshwater Bivalves held in 2012 in Bragança, Portugal
Refined 3d-3d correspondence.

We explore aspects of the correspondence between Seifert 3-manifolds and 3d   N  = 2 supersymmetric theories with a distinguished abelian flavour symmetry. We give a prescription for computing the squashed three-sphere partition functions of such 3d   N  = 2 theories constructed from boundary conditions and interfaces in a 4d   N  = 2∗ theory, mirroring the construction of Seifert manifold invariants via Dehn surgery. This is extended to include links in the Seifert manifold by the insertion of supersymmetric Wilson-’t Hooft loops in the 4d   N  = 2∗ theory. In the presence of a mass parameter cfor the distinguished flavour symmetry, we recover aspects of refined Chern-Simons theory with complex gauge group, and in particular construct an analytic continuation of the S-matrix of refined Chern-Simons theory
A spatiotemporal analysis of US station temperature trends over the last century

This study presents a nonlinear spatiotemporal analysis of 1167 station temperature records from the United States Historical Climatology Network covering the period from 1898 through 2008. We use the empirical mode decomposition method to extract the generally nonlinear trends of each station. The statistical significance of each trend is assessed against three null models of the background climate variability, represented by stochastic processes of increasing temporal correlation length. We find strong evidence that more than 50% of all stations experienced a significant trend over the last century with respect to all three null models. A spatiotemporal analysis reveals a significant cooling trend in the South-East and significant warming trends in the rest of the contiguous U.S. It also shows that the warming trend appears to have migrated equatorward. This shows the complex spatiotemporal evolution of climate change at local scales
Characterisation of the Mycobacterium tuberculosis alternative sigma factor SigG:Its operon and regulon

A major step in the pathogenesis of Mycobacterium tuberculosis is the ability to survive inside macrophages, where it is exposed to a number of DNA damaging agents. The alternative sigma factor SigG has been shown to be upregulated by DNA damaging agents and by macrophage infection, but not to regulate genes of the DNA repair pathway. Here we show that SigG is expressed from at least two promoters, the most dominant of these being the DNA damage inducible RecA_Ndp promoter. This promoter is located within the annotated coding region of SigG and so the correct translational start site was determined experimentally and found to be 114 bp downstream of the annotated start site. Examining the gene expression profile of a SigG over-expression strain found a small number of genes to up-regulated, two of these encoded proteins containing glyoxylase-like domains
Long-term carbon sink in Borneo’s forests halted by drought and vulnerable to edge effects

Less than half of anthropogenic carbon dioxide emissions remain in the atmosphere. While carbon balance models imply large carbon uptake in tropical forests, direct on-the-ground observations are still lacking in Southeast Asia. Here, using long-term plot monitoring records of up to half a century, we find that intact forests in Borneo gained 0.43 Mg C ha−1 per year (95% CI 0.14–0.72, mean period 1988–2010) in above-ground live biomass carbon. These results closely match those from African and Amazonian plot networks, suggesting that the world’s remaining intact tropical forests are now en masse out-of-equilibrium. Although both pan-tropical and long-term, the sink in remaining intact forests appears vulnerable to climate and land use changes. Across Borneo the 1997–1998 El Niño drought temporarily halted the carbon sink by increasing tree mortality, while fragmentation persistently offset the sink and turned many edge-affected forests into a carbon source to the atmosphere
Intelligence and negation biases on the Conditional Inference task:A dual-processes analysis

We examined a large set of conditional inference data compiled from several previous studies and asked three questions: How is normative performance related to intelligence? Does negative conclusion bias stem from Type 1 or Type 2 processing? Does implicit negation bias stem from Type 1 or Type 2 processing? Our analysis demonstrated that rejecting denial of the antecedent and affirmation of the consequent inferences was positively correlated with intelligence, while endorsing modus tollens inferences was not; that the occurrence of negative conclusion bias was related to the extent of Type 2 processing; and that the occurrence of implicit negation bias was not related to the extent of Type 2 processing. We conclude that negative conclusion bias is, at least in part, a product of Type 2 processing, while implicit negation bias is not
Di-photon Higgs signal at the LHC: a comparative study for different
  supersymmetric models

As the most important discovery channel for a light Higgs boson at the LHC,
the di-photon signal $gg->h->\gamma\gamma$ is sensitive to underlying physics.
In this work we investigate such a signal in a comparative way by considering
three different supersymmetric models, namely the minimal supersymmetric
standard model (MSSM), the next-to-minimal supersymmetric standard model
(NMSSM) and the nearly minimal supersymmetric standard model (nMSSM). Under the
current collider and cosmological constraints we scan over the parameter space
and obtain the following observation in the allowed parameter space: (i) In the
nMSSM the signal rate is always suppressed; (ii) In the MSSM the signal rate is
suppressed in most cases, but in a tiny corner of the parameter space it can be
enhanced (maximally by a factor of 2); (iii) In the NMSSM the signal rate can
be enhanced or suppressed depending on the parameter space, and the enhancement
factor can be as large as 7.Comment: Version in PLB (discussions added
Three-point functions in planar N=4 super Yang-Mills Theory for scalar
  operators up to length five at the one-loop order

We report on a systematic perturbative study of three-point functions in
planar SU(N) N=4 super Yang-Mills theory at the one-loop level involving scalar
field operators up to length five. For this we have computed a sample of 40
structure constants involving primary operators of up to and including length
five which are built entirely from scalar fields. A combinatorial dressing
technique has been developed to promote tree-level correlators to one-loop
level. In addition we have resolved the mixing up to the order (g_YM)^2 level
of the operators involved, which amounts to mixings with bi-fermions, with
bi-derivative insertions as well as self-mixing contributions in the scalar
sector. This work supersedes a preprint by two of the authors from 2010 which
had neglected the mixing contributions.Comment: 45, 5 tables, many figures. arXiv admin note: substantial text

Photometric catalog of nearby globular clusters (I)

We present the first part of the first large and homogeneous CCD
color-magnitude diagram (CMD) data base, comprising 52 nearby Galactic globular
clusters (GGC) imaged in the V and I bands using only two telescopes (one for
each hemisphere). The observed clusters represent 75% of the known Galactic
globulars with (m-M)v<=16.15 mag, cover most of the globular cluster
metallicity range (-2.2 <= [Fe/H] <= -0.4), and span Galactocentric distances
from ~1.2 to ~18.5 kpc.
  In this paper, the CMDs for the 39 GGCs observed in the southern hemisphere
are presented. The remaining 13 northern hemisphere clusters of the catalog are
presented in a companion paper. For four clusters (NGC 4833, NGC 5986, NGC
6543, and NGC 6638) we present for the first time a CMD from CCD data. The
typical CMD spans from the 22nd V magnitude to the tip of the red giant branch.
Based on a large number of standard stars, the absolute photometric calibration
is reliable to the ~0.02 mag level in both filters.
  This catalog, because of its homogeneity, is expected to represent a useful
data base for the measurement of the main absolute and relative parameters
characterizing the CMD of GGCs.Comment: 34 pages, 108 figures, Astronomy & Astrophysics Supplement Series, in

The investigation of the high frequency hopping conductivity in two- and
  three-dimensional electron gas by an acoustic method

High-frequency (HF) conductivity ($\sigma_{hf}$) measured by an acoustical
method has been studied in GaAs/AlGaAs heterostructures in a linear and
nonlinear regime on acoustic power. It has been shown that in the quantum Hall
regime at magnetic fields corresponding to the middle of the Hall plateaus the
HF conductivity is determined by the sum of the conductivity of 2-dimensional
electrons in the high-mobility channel and the hopping conductivity of the
electrons in the doped thick AlGaAs layer. The dependence of these
conductivities on a temperature is analyzed. The width of the Landau level
broadened by the impurity random potential is determined.Comment: RevTeX, 6 pages, 4 PS-figures, submitted to Phys.St.Sol.(Replaced

Time-Dependent CP Violation Effects in Partially Reconstructed $B^0 \to
  D^* \pi$ Decays

We report measurements of time-dependent decay rates for $B^0 \to D^{*\mp}
\pi^\pm$ decays and extraction of CP violation parameters related to $\phi_3$.
We use a partial reconstruction technique, whereby signal events are identified
using information only from the primary pion and the charged pion from the
decay of the $D^{*\mp}$. The analysis uses $140 {\rm fb}^{-1}$ of data
accumulated at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB
asymmetric-energy $e^{+}e^{-}$ collider. We measure the CP violation parameters
$S^+ = 0.035 \pm 0.041 ({\rm stat}) \pm 0.018 ({\rm syst})$ and $S^- = 0.025
\pm 0.041 ({\rm stat}) \pm 0.018 ({\rm syst})$.Comment: 15 pages, 5 figures. To appear in Physics Letters
Does CPT violation affect the B_d meson life times and decay
  asymmetries?

We study indirect CPT violating effects in B_d meson decays and mixing,
taking into account the recent constraints on the CPT violating parameters from
the Belle collaboration. The life time difference of the B_d meson mass
eigenstates, expected to be negligible in the standard model and many of its
CPT conserving extensions, could be sizeable (\sim a few percent of the total
width) due to breakdown of this fundamental symmetry. The time evolution of the
direct CP violating asymmetries in one amplitude dominated processes (inclusive
semileptonic B_d decays, in particular) turn out to be particularly sensitive
to this effect.Comment: 17 pages, 4 figures. Typos corrected and references adde
On the Equivalence Theorem in the $\chi PT$ Description of the Symmetry
  Breaking Sector of the Standard Model

We develop an alternative formulation of the symmetry breaking sector of the
Standard Model as a gauged non-linear sigma model (NLSM) following the
philosophy of the Chiral lagrangian approach, which is the only compatible with
all the experimental and theoretical constraints. We derive the BRS symmetry of
the model and the corresponding quantum lagrangian, which is a generalization
of the standard Faddeev-Popov method, in a way which is covariant with respect
to the reparametrizations of the coset space of the NLSM. Then we use the BRS
invariance of the quantum lagrangian to state the Equivalence Theorem for the
renormalized $S$-matrix elements calculated as a chiral expansion.Comment: LaTeX. Final version as it will appear in Nuclear Physics B (1994
Characters of the W3 algebra

Traces of powers of the zero mode in the W3 Algebra have recently been found
to be of interest, for example in relation to Black Hole thermodynamics, and
arise as the terms in an expansion of the full characters of the algebra. We
calculate the first few such powers in two cases. Firstly, we find the traces
in the 3-state Potts model by using null vectors to derive modular differential
equations for the traces. Secondly, we calculate the exact results for Verma
module representations. We compare our two methods with each other and the
result of brute-force diagonalisation for low levels and find complete
agreement.Comment: v2: Numerous small changes, version to appear in JHEP, 22 pages. v3:

Evolution and CNO yields of Z=10^-5 stars and possible effects on CEMP
  production

Our main goals are to get a deeper insight into the evolution and final fates
of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to
investigate their C, N, and O yields. Using the Monash University Stellar
Evolution code we computed and analysed the evolution of stars of metallicity Z
= 10^-5 and masses between 4 and 9 M_sun, from their main sequence until the
late thermally pulsing (super) asymptotic giant branch, TP-(S)AGB phase. Our
model stars experience a strong C, N, and O envelope enrichment either due to
the second dredge-up, the dredge-out phenomenon, or the third dredge-up early
during the TP-(S)AGB phase. Their late evolution is therefore similar to that
of higher metallicity objects. When using a standard prescription for the mass
loss rates during the TP-(S)AGB phase, the computed stars lose most of their
envelopes before their cores reach the Chandrasekhar mass, so our standard
models do not predict the occurrence of SNI1/2 for Z = 10^-5 stars. However, we
find that the reduction of only one order of magnitude in the mass-loss rates,
which are particularly uncertain at this metallicity, would prevent the
complete ejection of the envelope, allowing the stars to either explode as an
SNI1/2 or become an electron-capture SN. Our calculations stop due to an
instability near the base of the convective envelope that hampers further
convergence and leaves remnant envelope masses between 0.25 M_sun for our 4
M_sun model and 1.5 M_sun for our 9 M_sun model. We present two sets of C, N,
and O yields derived from our full calculations and computed under two
different assumptions, namely, that the instability causes a practically
instant loss of the remnant envelope or that the stars recover and proceed with
further thermal pulses. Our results have implications for the early chemical
evolution of the Universe.Comment: 12 pages, 13 figures, accepted for publication in A&
