Consumer Reactions to Former Price Comparisons in China
Abstract
Reference pricing is a common promotional activity in almost every contemporary business sector employed by marketers and normally aimed at increasing consumers' perceived product values and their possibility of purchasing. Reference prices are the standards against which the purchase price of a product is judged.
Since both the external and internal reference prices have been extensively researched by scholars of marketing in western countries such as the US and UK, this paper focus on consumers reactions to comparative price advertising in the Chinese market which is most attractive emerging market in the world.
The research adopts three independent variables: internal reference price, the presence of time limit restriction and the presence of former price (ARP), among which the IRP is a covariate variable. Five dependent variables are measured in the research: consumers perceived believability, transaction value, acquisition value, purchase intention and search intention.
This paper aims to answer the three main questions:
1. Whether or not Chinese Consumers use the internal reference price (IRP) in their evaluation of a comparative price promotion?
2. How does the presence of time limit affect Chinese consumers perception of price offers?
3. How does the presence of ARP affect Chinese consumers perception of price offers
Two-Dimensional Platinum Telluride with Ordered Te Vacancy Superlattice for Efficient and Robust Hydrogen Evolution
Defect engineering to activate the basal planes of transition metal
dichalcogenides (TMDs) is critical for the development of TMD-based
electrocatalysts as the chemical inertness of basal planes restrict their
potential applications in hydrogen evolution reaction (HER). Here, we report
the synthesis and evaluation of few-layer (7x7)-PtTe2-x with an ordered,
well-defined and high-density Te vacancy superlattice. Compared with pristine
PtTe2, (2x2)-PtTe2-x and Pt(111), (7x7)-PtTe2-x exhibits superior HER
activities in both acidic and alkaline electrolytes due to its rich structures
of undercoordinated Pt sites. Furthermore, the (7x7)-PtTe2-x sample features
outstanding catalytic stability even compared to the state-of-the-art Pt/C
catalyst. Theoretical calculations reveal that the interactions between various
undercoordinated Pt sites due to proximity effect can provide superior
undercoordinated Pt sites for hydrogen adsorption and water dissociation. This
work will enrich the understanding of the relationship between defect
structures and electrocatalytic activities and provide a promising route to
develop efficient Pt-based TMD electrocatalysts

Genome-wide identification of cystathionine beta synthase genes in wheat and its relationship with anther male sterility under heat stress
Cystathionine beta synthase (CBS) domains containing proteins (CDCPs) plays an important role in plant development through regulation of the thioredoxin system, as well as its ability to respond to biotic and abiotic stress conditions. Despite this, no systematic study has examined the wheat CBS gene family and its relation to high temperature-induced male sterility. In this study, 66 CBS family members were identified in the wheat genome, and their gene or protein sequences were used for subsequent analysis. The TaCBS gene family was found to be unevenly distributed on 21 chromosomes, and they were classified into four subgroups according to their gene structure and phylogeny. The results of collinearity analysis showed that there were 25 shared orthologous genes between wheat, rice and Brachypodium distachyon, and one shared orthologous gene between wheat, millet and barley. The cis-regulatory elements of the TaCBS were related to JA, IAA, MYB, etc. GO and KEGG pathway analysis identified these TaCBS genes to be associated with pollination, reproduction, and signaling and cellular processes, respectively. A heatmap of wheat plants based on transcriptome data showed that TaCBS genes were expressed to a higher extent in spikelets relative to other tissues. In addition, 29 putative tae-miRNAs were identified, targeting 41 TaCBS genes. Moreover, qRT-PCR validation of six TaCBS genes indicated their critical role in anther development, as five of them were expressed at lower levels in heat-stressed male sterile anthers than in Normal anthers. Together with anther phenotypes, paraffin sections, starch potassium iodide staining, and qRT-PCR data, we hypothesized that the TaCBS gene has a very important connection with the heat-stressed sterility process in wheat, and these data provide a basis for further insight into their relationship
