Effects of Narcissism, Leisure Boredom, and Gratifications Sought on User-Generated Content Among Net-Generation Users

This research identifies the gratifications sought by the net-generation when producing user-generated content (UGC) on the internet. Members of the Net-generation want to vent negative feelings, show affection to their frieds and relatives, be involved in others' lives, and fulfill their need to be recognized. These gratifications were all found to be significantly associated with the users' various levels of participation in UGC (e.g., Facebook, YouTube, blogs, online forums, etc.) What's more, narcissism was predictive of content generation in social networking sites, blogs, and personal webpage, while leisure boredom was significantly linked to expressing views in forums, updating personal website, and participating in consumer reviews. In particular, the results showed the Net-geners who encountered leisure boredom had a higher tendency to seek interaction with friends online. Implications of findings are discussed

Band-tunable color cone lasing emission based on dye-doped cholesteric liquid crystals with various pitches and a pitch gradient

[[abstract]]This study elucidates, for the first time, a novel band-tunable color cone lasing emission (CCLE) based on dye-doped cholesteric liquid crystal (DDCLC) films with various pitches. For several CLC cells with different pitches it was shown experimentally that the lasing band on the CCLE can be tuned among various color regions measured within different angular ranges. Some important features of the tunable CCLE are also identified and discussed. A spatially band-tunable color cone laser, based on a single DDCLC with a gradient pitch, is developed as a real application

Context-Aware Personalized Web Search Using Navigation History

It is highly desirable that web search engines know users well and provide just what the user needs. Although great effort has been devoted to achieve this dream, the commonly used web search engines still provide a “one-fit-all” results. One of the barriers is lack of an accurate representation of user search context that supports personalised web search. This article presents a method to represent user search context and incorporate this representation to produce personalised web search results based on Google search results. The key contributions are twofold: a method to build contextual user profiles using their browsing behaviour and the semantic knowledge represented in a domain ontology; and an algorithm to re-rank the original search results using these contextual user profiles. The effectiveness of proposed new techniques were evaluated through comparisons of cases with and without these techniques respectively and a promising result of 35% precision improvement is achieved.</jats:p

Computer-mediated communication in the L2 writing process: a review of studies between 2000 and 2017

As current computer-mediated communication (CMC) research is omnipresent in the foreign/second language (L2) writing process, a synthesis of the research in this realm is needed to better understand and inform the current pedagogical practices with technology in language classrooms. This article presents a review of 38 studies identifying the major characteristics of CMC use in L2 writing process and aspects of L2 writing where CMC is embedded. The findings indicate that a variety of CMC-embedded L2 writing tasks were mainly integrated in the drafting and revising/editing stages of writing. Also, there has been a clear shift in recent years from blogs and wikis to other CMC tools, such as Google Docs, Facebook, Skype, and instant messaging. Also, existing CMC research on the L2 writing process mainly focuses on improvement in L2 writing ability/production, complexity/accuracy/fluency (CAF) measures, interactivity in L2 writing, and learners' editing/revision strategies. Finally, this review discusses pedagogical implications and offers suggestions for future research on CMC and L2 writing
