Global consumer culture positioning: the use of global consumer culture positioning appeals across four European countries
This study proposes a framework of advertising appeals which could be used to express global consumer culture positioning (GCCP) strategy in advertising. The paper examines the use of such appeals in print advertising from four European countries comparing 847 advertisements for durable and non-durable goods from Poland, Hungary, Ireland and the UK. Contrary to expectations, GCCP appeals were more often used in advertisements for non-durable goods than durable goods. The study confirmed the expectation that GCCP appeals would be more frequently used in advertising in less developed markets than in more developed markets. The proposed framework of GCCP appeals may be useful to practitioners wishing to use this positioning strategy
Cultural Meaning, Advertising, and National Culture: A Four-Country Study
This document is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Global Marketing on 9 October 2017. Under embargo. Embargo end date: 9 April 2019. The final, published version is available online at http://www.tandfonline.com/doi/abs/10.1080/08911762.2017.1376364.Cultural meaning transfer theory and GLOBE dimensions were employed in this comparative study to examine the extent to which cultural meaning presented in advertisements reflected national cultures of the target countries. Content analysis was applied to advertisements from four countries to investigate whether the use of advertising appeals presented in these advertisements mirrored variations in cultures as described by GLOBE Society Values. Results revealed that, in line with the hypotheses, there were similarities and differences in the use of appeals, and only some of them mirrored the cultural variations. GLOBE Society Values were more likely to predict the use of appeals than GLOBE Society Practices, but not for all appeals. Advertisers can draw on national cultures for cultural meanings to be used in advertisements only to a limited extent. It may be that advertisements mold rather than mirror societal values, or that only certain cultural traits are important for advertisers.Peer reviewedFinal Accepted Versio

This study examined the effects of individual-level cultural values of individualism and collectivism on impulsive buying and money budgeting, and the mediating role of acculturation to global consumer culture. By applying the person-environment fit theory and acculturation theory, we argue that people who hold cultural values congruent with the culture they come into contact with are more likely to acculturate to it, and that those who acculturate to global consumer culture (GCC) are more likely to display consumption behaviors stimulated by GCC, namely impulsive buying and poor money budgeting. The findings show that consumers acculturated to GCC report higher impulsive buying and lower money budgeting, and that it is not the distinction between individualism and collectivism, but rather between the vertical and horizontal values that determines the acceptance of GCC and the studied consumption behaviors. Results revealed that vertical individualists (those who believe in competition between individuals and who prioritize their needs over the needs of others) and vertical collectivists (those who believe in the subordination of individuals to groups) were more likely to be acculturated to GCC. Thus, the acceptance of inequality between individuals amongst other individuals, or within groups, is related to the acceptance of GCC and impulsive buying and money budgeting. The level of acculturation to GCC mediates the relations between vertical individualism and collectivism values and impulsive buying and money budgeting. Theoretical contributions to the research on horizontal/vertical individualism/collectivism, acculturation to GCC, and person-environment fit theory, as well as practical implications for marketers are discussed
Theory of disordered unconventional superconductors
In contrast to conventional s-wave superconductivity, unconventional (e.g. p
or d-wave) superconductivity is strongly suppressed even by relatively weak
disorder. Upon approaching the superconductor-metal transition, the order
parameter amplitude becomes increasingly inhomogeneous leading to effective
granularity and a phase ordering transition described by the Mattis model of
spin glasses. One consequence of this is that at low enough temperatures,
between the clean unconventional superconducting and the diffusive metallic
phases, there is necessarily an intermediate superconducting phase which
exhibits s-wave symmetry on macroscopic scales.Comment: 5 pages, 2 figure
Identification of Regulatory Elements Using A Feature Selection Method
Many methods have been described to identify regulatory motifs in the transcription control regions of genes that exhibit similar patterns of gene expression across a variety of experimental conditions. Here we focus on a single experimental condition, and utilize gene expression data to identify sequence motifs associated with genes that are activated under this experimental condition. We use a linear model with two way interactions to model gene expression as a function of sequence features (words) present in presumptive transcription control regions. The most relevant features are selected by a feature selection method called stepwise selection with monte carlo cross validation. We apply this method to a publicly available dataset of the yeast Saccharomyces cerevisiae, focussing on the 800 basepairs immediately upstream of each gene\u27s translation start site (the upstream control region (UCR)). We successfully identify regulatory motifs that are known to be active under the experimental conditions analyzed, and find additional significant sequences that may represent novel regulatory motifs. We also discuss a complementary method that utilizes gene expression data from a single microarray experiment and allows averaging over variety of experimental conditions as an alternative to motif finding methods that act on clusters of co-expressed genes
Supervised Detection of Regulatory Motifs in DNA Sequences
Identification of transcription factor binding sites (regulatory motifs) is a major interest in contemporary biology. We propose a new likelihood based method, COMODE, for identifying structural motifs in DNA sequences. Commonly used methods (e.g. MEME, Gibbs sampler) model binding sites as families of sequences described by a position weight matrix (PWM) and identify PWMs that maximize the likelihood of observed sequence data under a simple multinomial mixture model. This model assumes that the positions of the PWM correspond to independent multinomial distributions with four cell probabilities. We address supervising the search for DNA binding sites using the information derived from structural characteristics of protein-DNA interactions. We extend the simple multinomial mixture model by incorporating constraints on the information content profiles or on specific parameters of the motif PWMs. The parameters of this extended model are estimated by maximum likelihood using a nonlinear constraint optimization method. Likelihood-based cross-validation is used to select model parameters such as motif width and constraint type. The performance of COMODE is compared with existing motif detection methods on simulated data that incorporate real motif examples from Saccharomyces cerevisiae. The proposed method is especially effective when the motif of interest appears as a weak signal in the data. Some of the transcription factor binding data of Lee et al. (2002) were also analyzed using COMODE and biologically verified sites were identified
Decoding human mental states by whole-head EEG+fNIRS during category fluency task performance
Objective: Concurrent scalp electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS), which we refer to as EEG+fNIRS, promises greater accuracy than the individual modalities while remaining nearly as convenient as EEG. We sought to quantify the hybrid system's ability to decode mental states and compare it with unimodal systems.
Approach: We recorded from healthy volunteers taking the category fluency test and applied machine learning techniques to the data.
Main results: EEG+fNIRS's decoding accuracy was greater than that of its subsystems, partly due to the new type of neurovascular features made available by hybrid data.
Significance: Availability of an accurate and practical decoding method has potential implications for medical diagnosis, brain-computer interface design, and neuroergonomics
Integromic analysis of genetic variation and gene expression identifies networks for cardiovascular disease phenotypes
BACKGROUND - : Cardiovascular disease (CVD) reflects a highly coordinated complex of traits. Although genome-wide association studies have reported numerous single nucleotide polymorphisms (SNPs) to be associated with CVD, the role of most of these variants in disease processes remains unknown. METHODS AND RESULTS - : We built a CVD network using 1512 SNPs associated with 21 CVD traits in genome-wide association studies (at P≤5×10) and cross-linked different traits by virtue of their shared SNP associations. We then explored whole blood gene expression in relation to these SNPs in 5257 participants in the Framingham Heart Study. At a false discovery rate <0.05, we identified 370 cis-expression quantitative trait loci (eQTLs; SNPs associated with altered expression of nearby genes) and 44 trans-eQTLs (SNPs associated with altered expression of remote genes). The eQTL network revealed 13 CVD-related modules. Searching for association of eQTL genes with CVD risk factors (lipids, blood pressure, fasting blood glucose, and body mass index) in the same individuals, we found examples in which the expression of eQTL genes was significantly associated with these CVD phenotypes. In addition, mediation tests suggested that a subset of SNPs previously associated with CVD phenotypes in genome-wide association studies may exert their function by altering expression of eQTL genes (eg, LDLR and PCSK7), which in turn may promote interindividual variation in phenotypes. CONCLUSIONS - : Using a network approach to analyze CVD traits, we identified complex networks of SNP-phenotype and SNP-transcript connections. Integrating the CVD network with phenotypic data, we identified biological pathways that may provide insights into potential drug targets for treatment or prevention of CVD
Self-consumption of electricity from renewable sources
If the cost of energy production from renewable energy sources (RES) reduces below the level of electricity retail prices, self-consumption (SC) can contribute to market integration of RES. Support schemes such as feed-in tariffs could be phased out in view of parity of retail prices and RES production costs. In combination with electricity storage and demand response (DR), SC can facilitate the integration of variable renewables onto the grid and lower the overall costs of the energy system through load shifting particularly if storage and DR is managed using ICT and algorithms controlling charging cycles and usage of electric devices.
Some issues remain however: Self-consumption potential is limited without further technical enhancements in storage or DR solutions. To organize self-consumption efficiently, measures on the grid side and energy storage have to be taken. Enabling the grid to provide necessary information back to prosumers and vice versa, as well as developing economic ways of storing energy is key to unleashing the potential that lies within the transition from passive consumers to active prosumers. Different policies, such as the support of investments to storage installations, can foster those developments.
The impact of electricity retail prices has to be considered also. Self-consumption is profitable if the costs of locally produced RES are lower than the retail electricity price. There are, however, worries that a high penetration of self-consumption solutions might lead to an unfair distribution of network charges, taxes and levies even if storage and DR measures can lower additional costs arising from PV integration. Future energy policy can address the way how costs get allocated
