For example, Mel Riddile points out that when one conditions on various measures of poverty, instead of trailing other nations, the U.S. actually comes out on top! He concludes that "when it comes to school improvement, it's poverty not stupid." Poverty causes educational deficiency. Now, I like to actually have data to play around with, in part because people have been known to lie about politically charged issues and in part because I like to have nice graphs (which are not provided by Riddile). Anyway, it turns out that international poverty data is pretty hard to come by and fraught with interpretational difficulties. On the other hand, the National Assessment of Educational Progress provides test data for most of the states in the U.S., and the U.S. Census Bureau provides data on the percentage of people in poverty by state. I took the NAEP data for 8th grade science achievement and regressed on the percentage of people below the poverty line for the measured states. The two are negatively associated: as poverty increases, science achievement scores decrease according to the relationship in the plot below. (Alaska, Kansas, Nebraska, and Vermont did not meet NAEP reporting guidelines and are not included in the plot above.) The association is highly significant (p=9.98*10-6). I also took pilot NAEP data for 8th grade mathematics achievement and regressed on the percentage of people below the poverty line for the measured states. (Evidently, the NAEP has only just started testing for mathematics achievement, and only eleven states were included in their pilot.) Again, the two are negatively associated. The slope of the relation turns out to be almost exactly the same as for science achievement. The association is not as significant, but it is still significant (p=0.0186). (My guess is the association is less significant in this case because fewer states were measured.) Clearly there is an association between poverty and achievement in science and mathem

The honeycomb framework defines how social media services focus on some or all of seven functional building blocks (identity, conversations, sharing, presence, relationships, reputation, and groups).

By applying a set of theories in the field of media research (social presence, media richness) and social processes (self-presentation, self-disclosure) Kaplan and Haenlein created a classification scheme for different social media types in their Business Horizons article published in 2010. According to Kaplan and Haenlein there are six different types of social media: collaborative projects (e.g., Wikipedia), blogs and microblogs (e.g., Twitter), content communities (e.g., YouTube), social networking sites (e.g., Facebook), virtual game worlds (e.g., World of Warcraft), and virtual social worlds (e.g. Second Life). Technologies include: blogs, picture-sharing, vlogs, wall-postings, email, instant messaging, music-sharing, crowdsourcing and voice over IP, to name a few. Many of these social media services can be integrated via social network aggregation platforms. Social media network websites include sites like Facebook, Twitter, Bebo and MySpace.

he authors explain that each of the seven functional building blocks has important implications for how firms should engage with social media. By analyzing identity, conversations, sharing, presence, relationships, reputation, and groups, firms can monitor and understand how social media activities vary in terms of their function and impact, so as to develop a congruent social media strategy based on the appropriate balance of building blocks for their community.[2]

Excerpts from Manufacturing Consent, Noam Chomsky interviewed by various interviewers - 0 views

QUESTION: When we talk about manufacturing of consent, whose consent is being manufactured? CHOMSKY: To start with, there are two different groups, we can get into more detail, but at the first level of approximation, there's two targets for propaganda. One is what's sometimes called the political class. There's maybe twenty percent of the population which is relatively educated, more or less articulate, plays some kind of role in decision-making. They're supposed to sort of participate in social life -- either as managers, or cultural managers like teachers and writers and so on. They're supposed to vote, they're supposed to play some role in the way economic and political and cultural life goes on. Now their consent is crucial. So that's one group that has to be deeply indoctrinated. Then there's maybe eighty percent of the population whose main function is to follow orders and not think, and not to pay attention to anything -- and they're the ones who usually pay the costs.

Interestingly, the blogosphere, including microblogging like Twitter, has undermined this manufacture of consent in some ways but also trivialized areas of major concern because of the emphasis on popularity and "like" type responses in social media. But social media has definitely changed the landscape and big data has changed the relationships with the entities in a position to influence and control information and frame issues within the public eye.
