    WHEN DOES NEGATIVE BRAND PUBLICITY HURT? The Moderating Influence of Analytic Versus Holistic Thinking

    Negative publicity can diminish positive consumer perceptions of a brand. We explore the impact of processing style on mitigating the effects of negative publicity. We hypothesize that holistic thinkers are less susceptible to negative publicity information than are analytic thinkers. Holistic thinkers are more likely to consider external context-based explanations for the negative publicity, resulting in little or no revision of beliefs about the parent brand. Analytic thinkers, in contrast, are less likely to consider contextual factors, attributing negative information to the parent brand and updating their brand beliefs accordingly. Across three studies, we find support for our predictions.Brand publicity, holistic thinking

    The influence of source attractiveness on self-perception and advertising effectiveness for 6- to 7-year-old children

    The objective of this article is to examine the effects of using attractive peer models in advertising for 6- to 7-year-old children. This age is important in children’s development, as children of that age are not yet fully aware of the persuasive intent of advertising, are more focused on perceptual than on cognitive information in ads and are more focused on irrelevant rather than relevant ad information. More insights are therefore needed about whether attractive advertising models influence self-perception and advertising effectiveness of children this young, in order to help policy makers, parents and advertisers understand these effects. Two experimental studies are presented in which children are exposed to ads with peer models. Results show that when children of 6- to 7-year-old rate advertising models as being more attractive, advertising effectiveness raises, but children’s perceived self-worth and children’s perceived physical attractiveness are unaffected. We conclude that 6- to 7- year-old children use model attractiveness as a perceptual cue to rate ads but are not yet using comparisons with these models to evaluate themselves

    The evolution and storage of primitive melts in the Eastern Volcanic Zone of Iceland: the 10 ka Grímsvötn tephra series (i.e. the Saksunarvatn ash)

    Major, trace and volatile elements were measured in a suite of primitive macrocrysts and melt inclusions from the thickest layer of the 10 ka GrĂ­msvötn tephra series (i.e. Saksunarvatn ash) at Lake HvĂ­tĂĄrvatn in central Iceland. In the absence of primitive tholeiitic eruptions (MgO > 7 wt.%) within the Eastern Volcanic Zone (EVZ) of Iceland, these crystal and inclusion compositions provide an important insight into magmatic processes in this volcanically productive region. Matrix glass compositions show strong similarities with glass compositions from the AD 1783–84 Laki eruption, confirming the affinity of the tephra series with the GrĂ­msvötn volcanic system. Macrocrysts can be divided into a primitive assemblage of zoned macrocryst cores (An_78–An_92, Mg#_cpx = 82–87, Fo_79.5–Fo_87) and an evolved assemblage consisting of unzoned macrocrysts and the rims of zoned macrocrysts (An_60–An_68, Mg#_cpx = 71–78, Fo_70–Fo_76). Although the evolved assemblage is close to being in equilibrium with the matrix glass, trace element disequilibrium between primitive and evolved assemblages indicates that they were derived from different distributions of mantle melt compositions. Juxtaposition of disequilibrium assemblages probably occurred during disaggregation of incompatible trace element-depleted mushes (mean La/Yb_melt = 2.1) into aphyric and incompatible trace element-enriched liquids (La/Yb_melt = 3.6) shortly before the growth of the evolved macrocryst assemblage. Post-entrapment modification of plagioclase-hosted melt inclusions has been minimal and high-Mg# inclusions record differentiation and mixing of compositionally variable mantle melts that are amongst the most primitive liquids known from the EVZ. Coupled high field strength element (HFSE) depletion and incompatible trace element enrichment in a subset of primitive plagioclase-hosted melt inclusions can be accounted for by inclusion formation following plagioclase dissolution driven by interaction with plagioclase-undersaturated melts. Thermobarometric calculations indicate that final crystal-melt equilibration within the evolved assemblage occurred at ~1140°C and 0.0–1.5 kbar. Considering the large volume of the erupted tephra and textural evidence for rapid crystallisation of the evolved assemblage, 0.0–1.5 kbar is considered unlikely to represent a pressure of long-term magma accumulation and storage. Multiple thermometers indicate that the primitive assemblage crystallised at high temperatures of 1240–1300°C. Different barometers, however, return markedly different crystallisation depth estimates. Raw clinopyroxene-melt pressures of 5.5–7.5 kbar conflict with apparent melt inclusion entrapment pressures of 1.4 kbar. After applying a correction derived from published experimental data, clinopyroxene-melt equilibria return mid-crustal pressures of 4±1.5 kbar, which are consistent with pressures estimated from the major element content of primitive melt inclusions. Long-term storage of primitive magmas in the mid-crust implies that low CO_2 concentrations measured in primitive plagioclase-hosted inclusions (262–800 ppm) result from post-entrapment CO_2 loss during transport through the shallow crust. In order to reconstruct basaltic plumbing system geometries from petrological data with greater confidence, mineral-melt equilibrium models require refinement at pressures of magma storage in Iceland. Further basalt phase equilibria experiments are thus needed within the crucial 1–7 kbar range.D.A.N. was supported by a Natural Environment Research Council studentship (NE/1528277/1) at the start of this project.
