This study seeks to extend the notion of the art infusion effect to an artistic intervention in a service context, and specify its mechanisms. Dual mediation by immersion and aesthetic experience may explain the experiential art infusion effect on brands. As a test of this prediction, this study investigates groups of customers who experience an artistic intervention in different conditions, characterised by two types of music (art-congruent vs. brand-congruent) and an artist's performance. Experiencing one of these artistic interventions increased brand attachment, relative to a control condition. Immersion and aesthetic experience (positive emotions) exerted a significant dual mediation effect on brand attachment when comparing the art-congruent music and the performance conditions. Interestingly, immersion and negative emotions did not reveal any mediating influence. [ABSTRACT FROM AUTHOR]

Lack of understanding of new products' positioning is one of the reasons proposed for their failure. Through a process of semantic transformation, product design can communicate a new product's positioning to consumers. Drawing on the theoretical foundations of implicit cognition and the results of an empirical study, this article demonstrates that the Semantic Priming Task is a valuable tool to evaluate perceived product positioning conveyed by product design and to help practitioners in their decision-making with regard to product design.

In previous experiments we were able to separate, using a nondestructive separation technique, culturable and nonculturable bacteria, from a Luria-Bertani (LB) medium culture of Escherichia coli incubated for 48 h. We observed in the nonculturable bacterial population an increase in oxidative damage and up-induction of most defenses against reactive oxygen species (ROS), along with a decrease in cytoplasmic superoxide dismutases. In this study, using the same separation technique, we separated into two subpopulations a 10-h LB medium culture containing only culturable bacteria. For the first time, we succeeded in associating physical separation with physiological differences. Although the levels of defense against ROS (RpoS, RpoH, OxyR, and SoxRS regulons) and oxidative damage (carbonyl contents) were apparently the same, we found that bacteria in one subpopulation were more sensitive to LB medium starvation and to various stresses, such as phosphate buffer starvation, heat shock, and hydrogen peroxide exposure. Based on these results, we suggest that these physiological differences reflect uncharacterized bacterial modifications which do not directly involve defenses against ROS.

Many physiological functions, such as the digestive function, are broad, complex scientific topics. Therefore, to build relevant, accessible claims about functional foods that relate to these functions, marketers need to understand what consumers know about them, in terms of the associated symptoms, diseases and health benefits. Such knowledge cannot be captured effectively through direct questioning; it requires implicit testing that can limit biases and reveal unconscious knowledge. For this study, 240 consumers were invited to participate in an implicit lexical decision task via an online platform, and their responses reveal that the concept of 'immunity' is associated in mothers' minds with three symptoms related to their personal experiences with their children. By measuring associations that emerge without pre-existing rational processes, this implicit measure offers a more precise picture of the semantic network for immunity, which consumers could not express explicitly in response to direct questioning. Thus the recommended protocol is not only new to market research but also adds substantial value to the tests that currently serve to dig into consumers' minds. [ABSTRACT FROM AUTHOR]

A study was conducted to understand the first events that occur when cells grown exponentially in liquid medium are transferred to a solid medium. The results indicate that in order to grow on plates, bacteria must not only adapt to new conditions but also perceive a real stress.

ABSTRACT Skin whitening has been studied mainly using a postcolonial attitude analysis emphasizing conscious reasons behind skin bleaching. Studies dedicated to gaining a rich understanding of nonconscious motivations for skin whitening are scarce, especially in Asia. Therefore, two studies were conducted by using an innovative mix of research protocols to access to both conscious and nonconscious motivations. The studies were conducted among 92 female regular skin whitening users, aged 18-24 years, in Bangkok, Thailand. Study 1, among 42 women, used three-combined qualitative research techniques of laddering, projective technique, and photo elicitation. Study 2 was conducted among 50 women to quantitatively test nonconscious motives implicitly associated with different white skin tones. The results revealed that motives are not linked to westernization. In a very competitive environment, light skin is seen as a strategic method to maintain men's loyalty, enhance self-esteem, and guarantee career success. Managerial and methodological implications for marketers are discussed. [ABSTRACT FROM AUTHOR]

According to grounded theories of cognition, knowledge is grounded in its sensory-motor features. Therefore, perceptual and conceptual processing should be based on the same distributed system so that conceptual and perceptual processes should interact. The present study assesses whether gustatory stimulation (participants tasted a sweet or a nonsweet yoghurt) could influence performance on a categorization task that involves the reactivation of the same sensory dimension. The results indicate that participants were slower (Experiment 1) or faster (Experiment 2), respectively, at categorizing pictures as representing edible sweet stimuli when they either simultaneously or had previously tasted a sweet yoghurt as compared to a nonsweet yoghurt. These results confirm the significant overlap between perceptual and memory mechanisms and suggest the functional equivalence between perceptually present and perceptually absent (memory reactivated) dimensions.

We investigated the effects of angry prosody, varying focus of attention, and laterality of presentation of angry prosody on peripheral nervous system activity. Participants paid attention to either their left or their right ear while performing a sex discrimination task on dichotically presented pseudo-words. These pseudo-words were characterized by either angry or neutral prosody and presented stereophonically (anger/neutral, neutral/anger, or neutral/neutral, for the left/right ear, respectively). Reaction times and physiological responses (heart period, skin conductance, finger and forehead temperature) in this study were differentially sensitive to the effects of anger versus neutral prosody, varying focus of attention, and laterality of presentation of angry prosody.

Forty Azospirillum strains were tested for their ability to synthesize N-acyl-homoserine lactones (AHLs). AHL production was detected for four strains belonging to the lipoferum species and isolated from a rice rhizosphere. AHL molecules were structurally identified for two strains: Azospirillum lipoferum TVV3 produces 3O,C8-HSL ( N-3-oxo-octanoyl-homoserine-lactone), C8-HSL ( N-3-octanoyl-homoserine-lactone), 3O,C10-HSL ( N-3-oxo-decanoyl-homoserine-lactone), 3OH,C10-HSL ( N-3-hydroxy-decanoyl-homoserine-lactone) and C10-HSL ( N-3-decanoyl-homoserine-lactone), whereas A. lipoferum B518 produced 3O,C6-HSL ( N-3-oxo-hexanoyl-homoserine-lactone), C6-HSL ( N-3-hexanoyl-homoserine-lactone), 3O,C8-HSL, 3OH,C8-HSL and C8-HSL. Genes involved in AHL production were characterized for A. lipoferum TVV3 by generating a genomic library and complementing an AHL-deficient strain with sensor capabilities. Those genes, designated alpI and alpR, were found to belong to the luxI and luxR families, respectively. When cloned in a suitable heterologous host, alpI and alpR could direct the synthesis of the five cognate AHLs present in A. lipoferum TVV3. These two adjacent genes were found to be located on a 85kb plasmid. Southern hybridization experiments with probes alpI/R indicated that genes involved in AHL production in the three other AHL-producing strains were not closely related to alpI and alpR. This study demonstrates that AHL-based quorum-sensing is not widespread among the genus Azospirillum and could be found only in some A. lipoferum strains. [ABSTRACT FROM AUTHOR]
