When Madison Avenue turns into Main Street: Consumer generated advertising as a marketing tool and its effects on online word of mouth

The purpose of this study is to investigate the effectiveness of consumer generated advertising as a marketing tool to encourage online word of mouth. Subsequently, the researchers aim to examine if there are certain design factors in consumer generated advertising that influence the effectiveness of consumer generated advertising in encouraging online word of mouth. The study conducts a multiple

Konceptbutiken - Ett Kinderägg i stor skala!

Vi har insett att det inte finns en tydlig definition av fenomenet konceptbutik. Vi upplever att innebörden av fenomenet därför anpassas till den egna verksamheten så att det blir vad man vill att det ska vara. Detta tror vi kan leda till förvirring kring vad en konceptbutik erbjuder och vad som förväntas av en sådan. Konceptbutiker handlar om att ge kunden något utöver det vanliga, där upplevelse

NADH electrocatalytic oxidation at glassy carbon paste electrodes modified with Meldola blue adsorbed on alpha-titanium phosphate

Basic electrochemistry of glassy carbon paste electrodes (GCPEs) modified with Meldola Blue adsorbed on crystalline a-titanium phosphate (MB-a-TP) electrodes and their ability to catalyze the NADH oxidation have been investigated. Various ratios of glassy carbon (Sigradur K) to MB-alpha-TP, were used to obtain GCPEs. Cyclic voltammetry (CV) and rotating disc electrode (RDE) measurements, performed

Association of a hydrophobically modified polyelectrolyte and a block copolymer followed by fluorescence techniques

By using absorption and fluorescence (steady-state and time-resolved) techniques the interaction between a poly(acrylic acid) PAA, randomly grafted with pyrene (Py) units (PAAMePy55) and a triblock copolymer of poly(ethylene oxide) and poly(propylene oxide) (EO20PO68EO20, P123) was investigated. From the fluorescence data it is shown that upon addition of P123 a decrease of the (pyrene-pyrene, Py-

Are Dutch Skylarks partial migrants? Ring recovery data and radio-telemetry suggest local coexistence of contrasting migration strategies

In recent years, Skylarks Alauda arvensis have undergone dramatic population declines in many European countries. Evidence exists for deteriorating conditions during the breeding season, but little is known about the situation during the rest of the annual cycle. Here we use two approaches to test if the Dutch breeding population of Skylarks consists of resident and/or migratory individuals. First

Complex Formation between a Fluorescently-Labeled Polyelectrolyte and a Triblock Copolymer

The association between a randomly pyrene labeled PAA polymer (PAAMePy55) and a PEO-PPO-PEO triblock copolymer (P123) in aqueous solutions of different NaCl concentrations and pHs has been studied by means of dynamic light scattering (DLS) and steady-state fluorescence spectroscopy at 40 °C. At acidic pH values, in the low P123/PAAMePy55 molar ratio regime (i.e., at low P123 concentrations), the r

Precise U-Pb baddeleyite age dating of the Usushwana Complex, southern Africa - Implications for the Mesoarchaean magmatic and sedimentological evolution of the Pongola Supergroup, Kaapvaal Craton

The Usushwana Complex of the south-eastern Kaapvaal Craton (South Africa and Swaziland), intrudes the ca. 3.6-3.1 Ga basement of the craton, as well as the Mesoarchaean volcanic and sedimentary cover succession of the Pongola Supergroup. New high-precision U-Pb dating of gabbros belonging to the Piet Retief Suite of the Usushwana Complex yield ages of 2989 +/- 1 Ma, 2990 +/- 2 Ma and 2978 +/- 2 Ma

Genetic and environmental influence on lung function impairment in Swedish twins

Background: The understanding of the influence of smoking and sex on lung function and symptoms is important for understanding diseases such as COPD. The influence of both genes and environment on lung function, smoking behaviour and the presence of respiratory symptoms has previously been demonstrated for each of these separately. Hence, smoking can influence lung function by co-varying not only

A multi-scale approach to hyperbolic evolution equations with limited smoothness

We discuss how techniques from multiresolution analysis and phase space transforms can be exploited in solving a general class of evolution equations with limited smoothness. We have wave propagation in media of limited smoothness in mind. The frame that appears naturally in this context belongs to the family of frames of curvelets. The construction considered here implies a full-wave description

Probing the Effects of One-Electron Reduction and Protonation on the Electronic Properties of the Fe-S Clusters in the Active-Ready Form of [FeFe]-Hydrogenases. A QM/MM Investigation.

A QM/MM investigation of the active-ready (Hox) form of [FeFe]-hydrogenase from D. desulfuricans, in which the electronic properties of all Fe-S clusters (H, F and F') have been simultaneously described using DFT, was carried out with the aim of disclosing a possible interplay between the H-cluster and the accessory iron-sulfur clusters in the initial steps of the catalytic process leading to H2 f

Fast Generation of Broken-Symmetry States in a Large System Including Multiple Iron-Sulfur Assemblies: Investigation of QM/MM Energies, Clusters Charges, and Spin Populations

A density functional theory study is presented regarding the energetics and the Mulliken population analyses of a quantum mechanical/molecular mechanical (QM/MM) system including multiple iron-sulfur clusters in the QM region. The [FeFe]-hydrogenase from Desulfovibrio desulfuricans was studied, and both the active site (an Fe6S6 assembly generally referred to as the H-cluster) and an ancillary Fe4

Frequency Extrapolation through Sparse Sums of Lorentzians

Sparse sums of Lorentzians can give good approximations to functions consisting of linear combination of piecewise continuous functions. To each Lorentzian, two parameters are assigned: translation and scale. These parameters can be found by using a method for complex frequency detection in the frequency domain. This method is based on an alternating projection scheme between Hankel matrices and f

Speciation chronology of rockhopper penguins inferred from molecular, geological and palaeoceanographic data

The Southern Ocean is split into several biogeographical provinces between convergence zones that separate watermasses of different temperatures. Recent molecular phylogenies have uncovered a strong phylogeographic structure among rockhopper penguin populations, Eudyptes chrysocome sensu lato, from different biogeographical provinces. These studies suggested a reclassification as three species in

In situ detection of soot nanoparticles by time-resolved fluorescence analysis

We present a new implementation of the time-resolved fluorescence anisotropy technique for the analysis of carbon nanoparticles directly in a Bunsen-type propane flame. By exploiting femtosecond laser excitation, UV-visible laser-induced fluorescence and time resolution of the experimental set-up, small soot nanoparticles have been identified within the flame. From the measurement of the decay tim

Exploration of the extracellular space by a large-scale secretion screen in the early Xenopus embryo

Secreted proteins playa crucial role in intercellular communication during embryogenesis and in the adult. We recently described a novel method, designated as secretion cloning, that allows identifying extracellular proteins exclusively based on their ability to be secreted by transfected cells. In this paper, we present the results of a large-scale screening of more than 90,000 clones from three

TSP with neighborhoods of varying size

In TSP with neighborhoods (TSPN) we are given a collection S of regions in the plane, called neighborhoods, and we seek the shortest tour that visits all neighborhoods. Until now constant-factor approximation algorithms have been known only for cases where the neighborhoods are of approximately the same size. In this paper we present the first polynomial-time constant-factor approximation algorith

The risk and burden of vertebral fractures in Sweden

The aim of this study was to determine the risk and burden of vertebral fractures judged as those coming to clinical attention and as morphometric fractures. Incidence and utility loss were computed from data from Malmo, Sweden. Clinical fractures accounted for 23% of all vertebral deformities in women and for 42% in men. The average 10-year fracture probability for morphometric fractures increase

Intervention thresholds for osteoporosis

The aim of this study was to determine the threshold of fracture probability at which interventions become cost-effective. We modeled the effects of a treatment costing $500/year, given for 5 years, that decreased the risk of all osteoporotic fractures by 35%, followed by a waning of effect for 5 years. Sensitivity analyses included a range of effectiveness (10%-50%) and a range of intervention co
