Internet Privacy and Institutional Trust: Insights From a National Survey
What does the US public believe about the credibility of institutional actors when it comes to protecting information privacy online? Drawing on perspectives of environmental risk, this article addresses the question through a nationally representative telephone survey of 1200 adults who go online at home. A key result is that a substantial percentage of internet users believes that major corporate or government institutions will both help them to protect information privacy and take that privacy away by disclosing information to other parties without permission. This finding and others raise questions about the dynamics of risk-perception and institutional trust on the web
Consumers’ Understanding of Privacy Rules in the Marketplace
Studies suggest the general structure of Web sites leads consumers away from demanding that online merchants take certain approaches to privacy as a condition for dealing with them. This article presents findings from a nationally representative survey showing that the absence of such a privacy marketplace can also be attributed to the public’s incomplete knowledge of privacy regulations. Most respondents correctly understood that regulations regarding merchants’ sharing information are domain specific. The respondents were only sporadically correct, however, regarding which domains have which rules. The study raises questions about the best approaches to education in the absence of a coherent national policy of privacy regulation
The Tradeoff Fallacy - How Marketers Are Misrepresenting American Consumers and Opening Them up to Exploitation
New survey results indicate that marketers are misrepresenting a large majority of Americans by claiming that Americans give out information about themselves as a tradeoff for benefits they receive. To the contrary, the survey reveals most Americans do not believe that ‘data for discounts’ is a square deal.
The findings also suggest, in contrast to other academics’ claims, that Americans’ willingness to provide personal information to marketers cannot be explained by the public’s poor knowledge of the ins and outs of digital commerce. In fact, people who know more about ways marketers can use their personal information are more likely rather than less likely to accept discounts in exchange for data when presented with a real-life scenario.
Our findings, instead, support a new explanation: a majority of Americans are resigned to giving up their data—and that is why many appear to be engaging in tradeoffs. Resignation occurs when a person believes an undesirable outcome is inevitable and feels powerless to stop it. Rather than feeling able to make choices, Americans believe it is futile to manage what companies can learn about them. Our study reveals that more than half do not want to lose control over their information but also believe this loss of control has already happened.
By misrepresenting the American people and championing the tradeoff argument, marketers give policymakers false justifications for allowing the collection and use of all kinds of consumer data often in ways that the public find objectionable. Moreover, the futility we found, combined with a broad public fear about what companies can do with the data, portends serious difficulties not just for individuals but also—over time—for the institution of consumer commerce.
 
Divided We Feel: Partisan Politics American\u27s Emotions Regarding Surveillance of Low-Income Populations
Americans Reject Tailored Advertising and Three Activities That Enable It
This nationally representative telephone (wire-line and cell phone) survey explores Americans\u27 opinions about behavioral targeting by marketers, a controversial issue currently before government policymakers. Behavioral targeting involves two types of activities: following users\u27 actions and then tailoring advertisements for the users based on those actions. While privacy advocates have lambasted behavioral targeting for tracking and labeling people in ways they do not know or understand, marketers have defended the practice by insisting it gives Americans what they want: advertisements and other forms of content that are as relevant to their lives as possible. Contrary to what many marketers claim, most adult Americans (66%) do not want marketers to tailor advertisements to their interests. Moreover, when Americans are informed of three common ways that marketers gather data about people in order to tailor ads, even higher percentages - between 73% and 86% - say they would not want such advertising. Even among young adults, whom advertisers often portray as caring little about information privacy, more than half (55%) of 18-24 years-old do not want tailored advertising. And contrary to consistent assertions of marketers, young adults have as strong an aversion to being followed across websites and offline (for example, in stores) as do older adults. This survey finds that Americans want openness with marketers. If marketers want to continue to use various forms of behavioral targeting in their interactions with Americans, they must work with policymakers to open up the process so that individuals can learn exactly how their information is being collected and used, and then exercise control over their data. We offer specific proposals in this direction. An overarching one is for marketers to implement a regime of information respect toward the public rather than to treat them as objects from which they can take information in order to optimally persuade them
Divided We Feel: Partisan Politics Drive American\u27s Emotions Regarding Surveillance of Low-Income Populations
Americans, Marketers, and the Internet: 1999-2012
This is a collection of the reports on the Annenberg national surveys that explored Americans\u27 knowledge and opinions about the new digital-marketing world that was becoming part of their lives. So far we’ve released seven reports on the subject, in 1999, 2000, 2003, 2005, 2009, 2010, and 2012. The reports raised or deepened a range of provocative topics that have become part of public, policy, and industry discourse. In addition to these reports, I’ve included three journal articles — from I/S, New Media & Society and the Journal of Consumer Affairs — that synthesize some of the findings and place them into policy frameworks.

The Seventh Data Release of the Sloan Digital Sky Survey
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey
(SDSS), marking the completion of the original goals of the SDSS and the end of
the phase known as SDSS-II. It includes 11663 deg^2 of imaging data, with most
of the roughly 2000 deg^2 increment over the previous data release lying in
regions of low Galactic latitude. The catalog contains five-band photometry for
357 million distinct objects. The survey also includes repeat photometry over
250 deg^2 along the Celestial Equator in the Southern Galactic Cap. A
coaddition of these data goes roughly two magnitudes fainter than the main
survey. The spectroscopy is now complete over a contiguous area of 7500 deg^2
in the Northern Galactic Cap, closing the gap that was present in previous data
releases. There are over 1.6 million spectra in total, including 930,000
galaxies, 120,000 quasars, and 460,000 stars. The data release includes
improved stellar photometry at low Galactic latitude. The astrometry has all
been recalibrated with the second version of the USNO CCD Astrograph Catalog
(UCAC-2), reducing the rms statistical errors at the bright end to 45
milli-arcseconds per coordinate. A systematic error in bright galaxy photometr
is less severe than previously reported for the majority of galaxies. Finally,
we describe a series of improvements to the spectroscopic reductions, including
better flat-fielding and improved wavelength calibration at the blue end,
better processing of objects with extremely strong narrow emission lines, and
an improved determination of stellar metallicities. (Abridged)Comment: 20 pages, 10 embedded figures. Accepted to ApJS after minor
