The Unofficial Google Data Science Blog The legitimacy and usefulness of academic blogging will shape how intellectualism develops Academic blogging has become an increasingly popular form, but key questions still remain over whether blog posts should feature more prominently in formal academic discourse. Jenny Davis clarifies the pros and cons of blog citation and sees the remaining ambiguity as indicative of a changing professional landscape. The wider scholarly community must learn how to grapple with these ethical and professional questions of rigor in standards of academic sourcing. In this post I attempt to tackle a complex but increasingly important question: Should writers cite blog posts in formal academic writing (i.e. journal articles and books)? Mostly, I cite Cyborgology and a select few blogs that I know really, really well. Well I mean, I know these bloggers to be good theorists, and I find their work useful for my own. With this poorly articulated rationale in mind, I present first, some pros and cons to citing blogs within formal academic writing. Pros and Cons of Blog Citation Pros Cons 1.) 2.) 3.)

Unintentional Knowledge - The Chronicle Review By Julio Alves I started teaching writing in graduate school 20-plus years ago, and it did not take me long to start looking forward to the pile of research papers at the end of the semester. Unlike much of the writing earlier in the semester, done from assigned readings and carefully crafted prompts, the research papers tackled broad, open-ended questions. Students developed their own ideas and went to the library to research topics of their choice. It was exciting to see how they made sense of what they read. But that was in the old days, before the ease and precision produced by the Internet. When I started teaching, books were easier to find than articles, whose references were buried deep in voluminous, thin-paged indexes. As periodical-search engines blossomed, students, ever adaptable, started using more articles. Then the development of Google and of electronic journals essentially converged. Consequently, my students hardly ever consult books. Skills for Online Searching - ipl2 A+ Research & Writing Learn how search syntax works Search syntax is a set of rules describing how users can query the database being searched. Sophisticated syntax makes for a better search, one where the items retrieved are mostly relevant to the searcher's need and important items are not missed. Boolean logic Boolean logic allows the use of AND, OR and NOT to search for items containing both terms, either term, or a term only if not accompanied by another term. Wildcards and truncation This involves substituting symbols for certain letters of a word so that the search engine will retrieve items with any letter in that spot in the word. Phrase searching Many concepts are represented by a phrase rather than a single word. Proximity This allows the user to find documents only if the search terms appear near each other, within so many words or paragraphs, or adjacent to each other. Capitalization Field searching All database records are divided up into fields. Make sure you know what content you're searching
