Interest in deliberative theories of democracy has grown tremendously among political theorists, political scientists, activists, and even government officials. Many scholars, however, are skeptical that it is a practically viable theory, even on its own terms. They argue (inter alia) that most people dislike politics and that deliberative initiatives would amount to a paternalistic imposition.

Social media, such as blogs, are often seen as democratic entities that allow more voices to be heard than the conventional mass or elite media. Some also feel that social media exhibits a balancing force against the arguably slanted elite media. A systematic comparison between social and mainstream media is necessary but challenging due to the scale and dynamic nature of modern communication.

We analyze a little-studied regulatory approach that we call management-based regulation. Management-based regulation directs regulated organizations to engage in a planning process that aims toward the achievement of public goals, offering firms flexibility in how they achieve public goals.

We live life in the network. We check our e-mails regularly, make mobile phone calls from almost any location, swipe transit cards to use public transportation, and make purchases with credit cards. Our movements in public places may be captured by video cameras, and our medical records stored as digital files. We may post blog entries accessible to anyone, or maintain friendships through online social networks.

Whether as team members brainstorming or cultures experimenting with new technologies, problem solvers communicate and share ideas. This paper examines how the structure of communication networks among actors can affect system-level performance. We present an agent-based computer simulation model of information sharing in which the less successful emulate the more successful.

How do attitudes and social affiliations coevolve? A long stream of research has focused on the relationship between attitudes and social affiliations. However, in most of this research the causal relationship between views and affiliations is difficult to discern definitively: Do people influence each other's views so that they converge over time or do they primarily affiliate (by choice or happenstance) with those of similar views?

DNA methods are now widely used for many forensic purposes, including routine investigation of serious crimes and for identification of persons killed in mass disasters or wars (1–4). DNA databases of convicted offenders are maintained by every U.S. state and nearly every industrialized country, allowing comparison of crime scene DNA profiles to one another and to known offenders (5).

How do decentralized systems deal with innovation? In particular, how do they aggregate the myriad experiences of their component parts, facilitate diffusion of information, and encourage investments in innovation? This is a classic problem in the study of human institutions.

Donald Trump has become well known for his shoot-from-the-hip tweeting style. Lots of insults, lots of rants and lots of energy. Data scientists who have examined all of Trump's tweets over time found he has some very clear Twitter strategies and tactics that, in many ways, have been working.
