The Insidious Effects of Smiles on Social Judgments

We propose that broad smiles increase perceptions of warmth but decrease perceptions of competence. These effects influence consumers' behavioral intentions and actual behaviors, and are moderated by level of consumption risk. Three studies, including one using data from Kickstarter.com, support these hypotheses

The Crest Phenotype in Chicken Is Associated with Ectopic Expression of HOXC8 in Cranial Skin

The Crest phenotype is characterised by a tuft of elongated feathers atop the head. A similar phenotype is also seen in several wild bird species. Crest shows an autosomal incompletely dominant mode of inheritance and is associated with cerebral hernia. Here we show, using linkage analysis and genome-wide association, that Crest is located on the E22C19W28 linkage group and that it shows complete association to the HOXC-cluster on this chromosome. Expression analysis of tissues from Crested and non-crested chickens, representing 26 different breeds, revealed that HOXC8, but not HOXC12 or HOXC13, showed ectopic expression in cranial skin during embryonic development. We propose that Crest is caused by a cis-acting regulatory mutation underlying the ectopic expression of HOXC8. However, the identification of the causative mutation(s) has to await until a method becomes available for assembling this chromosomal region. Crest is unfortunately located in a genomic region that has so far defied all attempts to establish a contiguous sequence

Difference Equations and Sharing Values Concerning Entire Functions and Their Difference

The value distribution of solutions of certain difference equations is investigated. As its applications, we investigate the difference analogue of the Brück conjecture. We obtain some results on entire functions sharing a finite value with their difference operators. Examples are provided to show that our results are the best possible

Comparative Time-Course Physiological Responses and Proteomic Analysis of Melatonin Priming on Promoting Germination in Aged Oat (<i>Avena sativa</i> L.) Seeds

Melatonin priming is an effective strategy to improve the germination of aged oat (Avena sativa L.) seeds, but the mechanism involved in its time-course responses has remained largely unknown. In the present study, the phenotypic differences, ultrastructural changes, physiological characteristics, and proteomic profiles were examined in aged and melatonin-primed seed (with 10 μM melatonin treatment for 12, 24, and 36 h). Thus, 36 h priming (T36) had a better remediation effect on aged seeds, reflecting in the improved germinability and seedlings, relatively intact cell ultrastructures, and enhanced antioxidant capacity. Proteomic analysis revealed 201 differentially abundant proteins between aged and T36 seeds, of which 96 were up-accumulated. In melatonin-primed seeds, the restoration of membrane integrity by improved antioxidant capacity, which was affected by the stimulation of jasmonic acid synthesis via up-accumulation of 12-oxo-phytodienoic acid reductase, might be a candidate mechanism. Moreover, the relatively intact ultrastructures enabled amino acid metabolism and phenylpropanoid biosynthesis, which were closely associated with energy generation through intermediates of pyruvate, phosphoenolpyruvate, fumarate, and α-ketoglutarate, thus providing energy, active amino acids, and secondary metabolites necessary for germination improvement of aged seeds. These findings clarify the time-course related pathways associated with melatonin priming on promoting the germination of aged oat seeds

Adapting To Succeed? Leveraging The Brand Equity Of Best Sellers To Succeed At The Box Office

Many movies are based on best-selling novels. While book adaptation is an often used strategy in the motion picture industry, it has received little academic attention. Using a multi-method approach, this research investigates the drivers behind the success of book-based movies. In Study 1, we analyze over 700 movies and find that book-based movies perform better at the box office on the opening weekend than non-book movies. However, this superior performance dissipates after the opening weekend. Further, the opening weekend performance of book-based movies is positively driven by book equity, book-movie similarity, and recency between the book\u27s peak equity and movie release. After the opening weekend, many of these book-related variables cease to have an impact, and the effect of movie-related variables (e.g., reviews) increases. Because Study 1 documents that book-movie similarity positively impacts the movie\u27s performance, contrary to prior findings that content similarity has negative or null impact on performance of a movie sequel, we undertake a second study to reconcile the discrepancy. Study 2 finds that content similarity results in satiation and therefore hampers the movie success for sequels; however, when a movie is adapted from a book, due to experiential modality change (i.e., from book format to film format rather than film to film), content similarity increases the movie\u27s chance of success. © 2010 Academy of Marketing Science

Effects Of Prototype And Exemplar Fit On Brand Extension Evaluations: A Two-Process Contingency Model

The brand extension literature suggests that consumers will favorably evaluate a brand extension when (a) it has high fit with the brand and (b) the brand has positive evaluations. We suggest that when a brand operates in multiple product domains, extension evaluations are more complex than have been conceptualized, and favorable consumer responses may result even in the absence of the above two conditions. Our two-process contingency model proposes two dimensions of fit (brand prototype fit and product exemplar fit) and two evaluative processes (topdown and parallel attitude transfer) that drive extension evaluations in different ways, depending on the level of cognitive resources. Three empirical studies found consistent support for the model. © 2006 by JOURNAL OF CONSUMER RESEARCH, Inc
