Motivating purchase of private brands: Effects of store image, product signatureness, and quality variation

This study examines the effects of intangible extrinsic cues on consumer quality perception and purchase intention of private brands. We find that store image and product signatureness enhance quality perception and purchase intention of private brands while quality variation reduces both outcomes. All effects of the three extrinsic cues on purchase intention are partially mediated by quality perception. In addition, consumer value consciousness strengthens the relationship between quality perception and purchase intention of private brands.Private brands Store image Product signatureness Quality variation Quality perception Purchase intention

Partitioning or Bundling? Perceived Fairness of the Surcharge Makes a Difference

Partitioned pricing charges a base price and a surcharge instead of an equivalent all-inclusive price. In contrast, a bundling strategy offers a bundled price instead of separate prices for products in one package. Which pricing practice is more profitable? Previous research has shown conflicting results. This research identifies the boundary conditions which circumscribe the profitability of partitioned and bundled pricing. Results of three experiments indicate that the relative significance of the surcharge to the base price influences consumers\u27 perception of the fairness of the surcharge, which in turn influences consumer purchase intentions. Furthermore, given the same level of surcharge, consumers\u27 perceptions of the fairness of the surcharge moderates the effect of the pricing strategies. Thus, perceived fairness of the surcharge appears to be the key in determining whether or not the partitioning strategy is more profitable than the bundling strategy

A cross-national study of intergenerational influence: US and PRC

Purpose - The purpose of this study is to examine the intergenerational influence across dyads of mothers and daughters from the USA and the People's Republic of China (PRC), with a particular interest in discovering the cross-national differences in terms of the level of mother-daughter brand preference agreement, the directional influence from daughter to mother and leading factors for the observed differences

Product Fit and Consumer Attitude Toward Brand Extensions: The Moderating Role of Product Involvement

It is proposed that product involvement provides a situational motivation for consumers to discount the importance of product fit in brand extension evaluations. An experimental study with multiple brand extensions was conducted to test this hypothesis. It is found that the hypothesis holds in the case of complementarity between parent brand and extension product. A personality variable, need for cognition (NFC) is further applied to test the underlying principle and results support the argument

Flt3 Activation Mitigates Mitochondrial Fragmentation and Heart Dysfunction through Rebalanced L-OPA1 Processing by Hindering the Interaction between Acetylated p53 and PHB2 in Cardiac Remodeling

Recent studies have shown that FMS-like receptor tyrosine kinase 3 (Flt3) has a beneficial effect on cardiac maladaptive remodeling. However, the role and mechanism of Flt3 in mitochondrial dynamic imbalance under cardiac stress remains poorly understood. This study aims to investigate how Flt3 regulates p53-mediated optic atrophy 1 (OPA1) processing and mitochondrial fragmentation to improve cardiac remodeling. Mitochondrial fragmentation in cardiomyocytes was induced by isoprenaline (ISO) and H2O2 challenge, respectively, in vitro. Cardiac remodeling in mice was established by ligating the left anterior descending coronary artery or by chronic ISO challenge, respectively, in vivo. Our results demonstrated that the protein expression of acetylated-p53 (ac-p53) in mitochondria was significantly increased under cell stress conditions, facilitating the dissociation of PHB2-OPA1 complex by binding to prohibitin 2 (PHB2), a molecular chaperone that stabilizes OPA1 in mitochondria. This led to the degradation of the long isoform of OPA1 (L-OPA1) that facilitates mitochondrial fusion and resultant mitochondrial network fragmentation. This effect was abolished by a p53 K371R mutant that failed to bind to PHB2 and impeded the formation of the ac-p53-PHB2 complex. The activation of Flt3 significantly reduced ac-p53 expression in mitochondria via SIRT1, thereby hindering the formation of the ac-p53-PHB2 complex and potentiating the stability of the PHB2-OPA1 complex. This ultimately inhibits L-OPA1 processing and leads to the balancing of mitochondrial dynamics. These findings highlight a novel mechanism by which Flt3 activation mitigates mitochondrial fragmentation and dysfunction through the reduction of L-OPA1 processing by dampening the interaction between ac-p53 and PHB2 in cardiac maladaptive remodeling
