Travel blogs on China as a destination image formation agent: A qualitative analysis using Leximancer

The Internet spreads tourism information around the world and specifically travel blogs function as an online version of word-of-mouth (eWOM). This research explored the role of blogs as a destination image formation agent for China's inbound tourism. Data were collected from 630 bloggers who wrote on two blog websites about their travels within China in 2011 and 2012. The bloggers on TravelBlog.org and TravelPod.com were mainly from English-speaking countries. Qualitative analysis using Leximancer software was applied and identified nine major textual themes and the relationships among these themes. In order of relative importance, the themes were place, Chinese, people, food, train, city, hotel, China, and students. The research indicated that international tourists tended to have positive images of China

The effects of Virtual Reality tourism involvement on place attachment and behavioral intentions: Virtual Reality tourism of the Yellow Crane Tower in Wuhan

The main purpose of this research was to explore the relationships among virtual reality tourism involvement (VRTI), place attachment, and behavioral intentions. Based on involvement theory, VRTI was defined as user experiences of the landscape and activities of tourist attractions in an immersive way beyond time and space with the help of virtual reality (VR) technology at home through the Internet. The VR panoramic video of the Yellow Crane Tower in Wuhan, Hubei Province, China was the context, and 693 valid questionnaires were analyzed through AMOS 24.0. VRTI (pleasure, sign, and centrality) had significant positive effects on place attachment. Pleasure and sign had significant positive influences on behavioral intentions, while centrality had a significant negative effect. Place identity had a significant positive effect on behavioral intentions, whereas place dependence had no effect. Place dependence had a partial mediating effect between pleasure, centrality, and behavioral intentions, as well as a complete mediating effect between sign and behavioral intentions. Place identity played a partial mediating role between pleasure, centrality, and sign and behavioral intentions. VRTI explores the three-way interaction of "virtual tourism destinations - tourists - real tourism destinations", a novel human-place relationship of emotional attachment. This study expands the research on place attachment and tourist behavioral decisions, enriches the contents by applying involvement theory, proposes management strategies for VR tourism development, and provides new insights for destination marketing

Plasmonic Multi‐Layered Built‐in Hotspots Nanogaps for Effectively Activating Analytes

Abstract Multi‐layered plasmonic nanostructures are able to highly promote the near‐field confinement and effectively activate analytes, which are of predominate significance but are extremely challenging. Herein, the semi‐open Au core@carved AuAg multi‐shell superstructure nanoparticles (multi‐Au@Ag‐Au NPs, multi = mono, bi, tri, tetra, and penta) are reported with a high designability on electromagnetic field and capability of effectively capturing analytes. By controlling synthetic parameters such as the number of galvanic exchange and Ag growth, multi‐Au@Ag‐Au NPs are successfully obtained, with tunable layer numbers and asymmetric nanoholes. Due to collective plasmon oscillations of multi‐layered built‐in nanogaps, the electromagnetic field strength of a single penta‐Au@Ag‐Au entity reach 48841. More importantly, the penta‐Au@Ag‐Au NPs show a remarkable light‐harvesting capability, which is adaptive to different Raman lasers, supporting high‐diversity detection. Additionally, the structural specificity allows analytes to be sufficiently captured into interior hotspots, and further achieve highly sensitive detection with limit of detection down to 3.22 × 10−12 M. This study not only provides an effective pathway for integrating abundant hotspots and activating target molecules in single plasmonic superstructure, but stimulates advancements in SERS substrates for various applications

Development of genetic markers linked to straighthead resistance through fine mapping in rice (Oryza sativa L.).

Straighthead, a physiological disorder characterized by sterile florets and distorted spikelets, causes significant yield losses in rice, and occurs in many countries. The current control method of draining paddies early in the season stresses plants, is costly, and wastes water. Development of resistant cultivar is regarded as the most efficient way for its control. We mapped a QTL for straighthead resistance using two recombinant inbred line (RIL) F(9) populations that were phenotyped over two years using monosodium methanearsonate (MSMA) to induce the symptoms. One population of 170 RILs was genotyped with 136 SSRs and the other population of 91 RILs was genotyped with 159 SSRs. A major QTL qSH-8 was identified in an overlapping region in both populations, and explained 46% of total variation in one and 67% in another population for straighthead resistance. qSH-8 was fine mapped from 1.0 Mbp to 340 kb using 7 SSR markers and further mapped to 290 kb in a population between RM22573 and InDel 27 using 4 InDel markers. SSR AP3858-1 and InDel 11 were within the fine mapped region, and co-segregated with straighthead resistance in both RIL populations, as well as in a collection of diverse global accessions. These results demonstrate that AP3858-1 and InDel 11 can be used for marker-assisted selection (MAS) for straighthead resistant cultivars, which is especially important because there is no effective way to directly evaluate straighthead resistance
