Based on the findings of trigger events research, prospect theory and emotional attachment theory, this article identifies three attributes of consumers' perception of brand acquisition (i.e. the type of acquisition, perceived fit and separation emotion) and applies an experiment to examine their effects on the brand acquisition. The result suggests that all of the three attributes impact the brand equity significantly and the brand equity declined when the participants perceived the brand acquisition. Specifically, the focal brand equity is significantly different in two common types of brand acquisition, and it's impacted by perceived fit positively while it's impacted by separation emotion negatively. Managers are advised to consider the impact of the brand acquisition per se on the consumers' perception to avoid the loss of brand equity in the beginning of the brand acquisition and lay the root for the long-term benefit.

The purpose of this paper is to introduce a dual-mode of trade-consumer show, which is a new mode that was applied in Guangzhou & Taiwan Products Expo广州台湾产品博览会 (GTPE). The paper puts forward the definition and illustrates features of this dual-mode, and analyzes the merits, risks as well as countermeasures through the case of GTPE. Study findings indicate the dual-mode of trade-consumer show may trigger the innovations in exhibition theme planning.

Background & Objective:: In past few years, Cognitive Radio (CR) paradigm has emerged as a promising and revolutionary solution to avoid problems of spectrum paucity and inefficiency in spectrum usage. Efficiently utilization of the spectrum offers high network performance. CRs are proficient to identify and adopt the unused spectrum in order to allow secondary users to occupy it without interfering the primary user’s activity. Cognitive Internet on Things (CIoT) is an integration of several technologies and communication solutions which can be effectively realized as Cognitive Radio Adhoc Networks (CRAHN). In CRANH, on-demand routing protocols are the best suitable protocols due to their dynamic feature of available un-utilized channel/spectrum selection. Methods: Here, firstly, Ad-Hoc On-Demand Distance Vector (AODV) routing protocol has been modified and further evaluated to address route selection challenges in CIoT framework. Secondly, the effects on network performance under network layer routing attacks (i.e. blackhole attack, byzantine attack and flooding attacks) are evaluated. Conclusion: The simulations results demonstrate network performance increase with more channels and degrade differently under attacks.
