Coursera's chief executive officer, Rick Levin, is stepping down, the online education provider said Tuesday. Levin, a former president of Yale University, joined Coursera in 2014 and will shift to a senior adviser role, according to a spokesperson. Under Levin, Coursera raised more than $100 million in equity funding and expanded both geographically and into new forms of credentials. Jeff Maggioncalda, former CEO of the asset management company Financial Engines, was named as Levin's replacement.
The idea of a product that, at a glance, can point scholars to the exact point in a book that is relevant to their research may sound like science fiction, but that’s how the scholarly database JSTOR is pitching a recently released research tool. The tool, called Topicgraph, is part of a JSTOR project to take the digital scholarly monograph from a PDF to something more useful for researchers.
Facebook is testing new features in its developer community that, if rolled out across the platform, could let anyone on the social networking service teach online courses. Moderators of some Facebook groups listed as school or class have recently noticed that they can add course units that link to one another. As members of the groups work their way through the units, their efforts are tracked by a progress bar.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Obama AND Romney or Obama + Romney.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used.) For example, search for democrat OR republican to find results that refer to
Democrats and/or Republicans.
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
