For the company, the most important thing is to understand how the various factors of reviews influence the purchase intention. Therefore, we took this issue as the core and investigated the influence of eWOM on purchase intention based on helpfulness, credibility, information quality and professionalism. We adopted feature filtering algorithms and proposed an ensemble model to integrate these

As patents can form an endowment shield that protects the development of corporate capabilities, companies are actively increasing their number of patents and attaching importance to technological research and development and patent management to achieve differentiated strategic effects. As such, patent layout and research and development (R&D) investment have become important strategic weapons for Taiwanese manufacturers, with which to enter the international market or compete among enterprises.

Making clear the “black box” between Perceived Organisational Support and Resistance to Change is crucial to predict the success of organizational change. Drawing upon organizational support theory and conservation of resources theory, this research was conducted in an attempt to offer a systematic analysis on employees' positive psychology in organizational change. The total valid sample consisted of 288 employees from Taiwanese consumer electronics manufacturing which were undergoi

We considered the online community as an animal flock, where members of the community are individual animals. The change in the direction of community discussions is analogous to the migration of an animal flock, although this occurs in virtual rather than physical space. To accurately formulate the community dynamics, we established a virtual space by using the

To help marketers choose the target members for physical direct mails, we modify the customer’s preference index of our original model to predict members’ repurchase rates for a physical supermarket’s members. Based on members’ predicted repurchase rates, marketers can design proper marketing strategies for different types of supermarket member to improve marketing effectiveness.

C K-edge XANES spectra of rGOs reveal that thermal reduction restores C = C sp2 bonds and removes some of the oxygen and hydroxyl groups of GO, which initiates the evolution of carbonaceous species. The combination of C K-edge XANES and Kα XES spectra shows that the overlapping π and π* orbitals in rGOs and GO are similar to that of highly ordered pyrolytic graphite (HOPG), which has no band-gap. C Kα RIXS spectra provide evidence that thermal reduction changes

However, its PEC performance is much limited by the sluggish charge transfer kinetics at the α‐Fe2O3/electrolyte interface. Herein, an insulative metal oxide, hafnium dioxide (HfO2), is deposited on the surface of α‐Fe2O3 to engineer the photoelectrode/electrolyte interfacial electronic structure. With the conformal HfO2 overlayer coating, the surface defects of α‐Fe2O3 are effectively passivated, whereas the charge migration from α‐Fe2O3 to the electrolyte is blocked by the continuous HfO2 overlayer, leadi

Choug-C3N4;Localized surface plasmon resonance;X-ray absorption spectroscopyApplied Surface Science 514, 145907Graphitic carbon nitride (g-C3N4) has attracted considerable attention with regard to its use in photocatalytic solar hydrogen production by the splitting of water. High charge carrier recombination critically limits the photocatalytic activity of g-C3N4. Plasmonic metal nanoparticles that can generate localized surface plasmon resonance (LSPR) have been suggested to enhance the harvesting of visible light and to improve water splitting efficiency. However, direct contact between metal nanoparticles and g-C3N4 reduc
