Blogging: an opportunity for librarians to communicate, participate and collaborate on a global scale

Blogs are an important element of the second generation of the web; or ‘Web 2.0’ as it is commonly referred to. ‘Web 2.0’ refers to the evolution from static "read only" web pages (Web 1.0) to dynamic, interactive pages encouraging users to create, interact and share content across multiple applications (O’Reilly, 2005). Blogging, along with other Web 2.0 technologies such as social networking, wikis, social bookmarking, photo sharing, video sharing, and microblogging, form part of the emergent ‘social media’ family; a collection of online tools that encourage users to communicate, participate, and collaborate on a global scale. Many library and information professionals have embraced blogging as a platform to document their career, enhance their profile, network with other librarians; and share anecdotes about their lives as librarians. The aim of this article is to present a brief overview of the history of blogs and a short review of literature related to blogging, libraries and reference librarians. It will also provide a list of recommended blogs, a discussion of the advantages of reading and writing blogs and some top tips for starting up your own blog

A facile route to a novel aza-crown ether incorporating three thiophene moieties

The preparation of the first of a novel type of large thiophene-containing aza-crown ether is reported. The macrocycle is synthesised by linking a 3,4-dialkoxythiophene moiety with two 3-hydroxythiophene units and ring closure is effected by reaction with piperazine via the Mannich reaction

Pose, posture, formation and contortion in kinematic systems

The concepts of pose, posture, formation and contortion are defined for serial, parallel and hybrid kinematic systems. Workspace and jointspace structure is examined in terms of these concepts. The inter-relationships of pose, posture, formation and contortion are explored for a range of robot workspace and jointspace types
