In scholarly and scientific publishing, altmetrics are non-traditional metrics proposed as an alternative to more traditional citation impact metrics, such as impact factor and h-index. The term altmetrics was proposed in 2010, as a generalization of article level metrics, and has its roots in the #altmetrics hashtag. Although altmetrics are often thought of as metrics about articles, they can be applied to people, journals, books, data sets, presentations, videos, source code repositories, web pages, etc. They are related to Webometrics, which had similar goals but evolved before the social web. Altmetrics did not originally cover citation counts. It also covers other aspects of the impact of a work, such as how many data and knowledge bases refer to it, article views, downloads, or mentions in social media and news media.

The data shared in June by the Office for Civil Rights, which compiled it from a 2013-2014 survey completed by nearly every school district and school in the United States. new is a report from Attendance Works and the Everyone Graduates Center that encourages schools and districts to use their own data to pinpoint ways to take on the challenge of chronic absenteeism.
The first is research that shows that missing that much school is correlated with “lower academic performance and dropping out.” Second, it also helps in identifying students earlier in the semester in order to get a jump on possible interventions.
The report offers a six-step process for using data tied to chronic absence in order to reduce the problem.
The first step is investing in “consistent and accurate data.” That’s where the definition comes in — to make sure people have a “clear understanding” and so that it can be used “across states and districts” with school years that vary in length. The same step also requires “clarifying what counts as a day of attendance or absence.”
The second step is to use the data to understand what the need is and who needs support in getting to school. This phase could involve defining multiple tiers of chronic absenteeism (at-risk, moderate or severe), and then analyzing the data to see if there are differences by student sub-population — grade, ethnicity, special education, gender, free and reduced price lunch, neighborhood or other criteria that require special kinds of intervention.
Step three asks schools and districts to use the data to identify places getting good results. By comparing chronic absence rates across the district or against schools with similar demographics, the “positive outliers” may surface, showing people that the problem isn’t unstoppable but something that can be addressed for the better.
Steps five and six call on schools and districts to help people understand why the absences are happening, develop ways to address the problem.
AT&T, Comcast, Verizon, and Time Warner have a “natural monopoly” since they’ve simply been at it the longest. While the Telecommunications Act of 1996 attempted to incentivize competition to upset these established businesses, it didn’t take into account the near impossibility of doing so. As Howard Zinn wrote in A People’s History of the United States, the Telecommunications Act of 1996 simply “enabled the handful of corporations dominating the airwaves to expand their power further.”
Chattanooga has somewhat famously installed its own. Santa Monica also has its own fiber network. The reason these communities have been successful is because they don’t look at these networks as a luxury, but as a mode of self sustainability.
The 19th century’s ghost towns exist because the gold ran out. The 21st century’s ghost towns might materialize because the Internet never showed up.

enerally speaking, Google has very limited interest in making hardware in the first place. The cost of building things is high, the margins are low, and Google’s real specialty is in web services like Gmail and search anyway.
the real business opportunity for Google is to compel a broad range of companies to create gadgets and home appliances using its software. The hardware is secondary. In fact, building its own hardware can even work against Google: The more successful Google is at selling its own hardware, the less likely other hardware makers want to use its software, since they view Google as a competitor.
Putting all its efforts behind expanding and extending Android has made Google a top player in the smartphone market, even after its late start against Apple and the iPhone.
