When Contact Changes Minds
"When contact changes minds: An experiment on transmission of support for gay equality" is a fraudulent article by then-UCLA political science graduate student Michael LaCour and Columbia University political science professor Donald Green. The article was published in the academic journal ''Science'' in December 2014, and retracted in May 2015 after it emerged that the data in the study had been forged by LaCour. The article purported to demonstrate that people's minds on the issue of gay marriage could be changed by conversations with gay canvassers, but not with straight canvassers. Study The authors claimed to have investigated whether gay or straight messengers were effective at encouraging voters to support same-sex marriage and whether attitude change persisted and spread to others in voters’ social networks. The purported results, measured by an unrelated panel survey, show that both gay and straight canvassers produced large effects initially, but only gay canvassers ...

Retraction Watch
Retraction Watch is a blog that reports on retractions of scientific papers and on related topics. The blog was launched in August 2010 and is produced by science writers Ivan Oransky (Former Vice President, Editorial '' Medscape'') and Adam Marcus (editor of ''Gastroenterology & Endoscopy News''). Its parent organization is the Center for Scientific Integrity. Scope Oransky and Marcus were motivated to launch ''Retraction Watch'' to increase the transparency of the retraction process. They observed that retractions of papers generally are not announced, that the reasons for retractions are not publicized, and that other researchers or the public who are unaware of the retraction may make decisions based on invalid results. Oransky described an example of a paper published in ''Proceedings of the National Academy of Sciences'' which reported a potential role for a drug against some types of breast cancers. Although the paper was later retracted, its retraction was not reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Watergat ...

Raw Data
Raw data, also known as primary data, are ''data'' (e.g., numbers, instrument readings, figures, etc.) collected from a source. In the context of examinations, the raw data might be described as a raw score (after test scores). If a scientist sets up a computerized thermometer which records the temperature of a chemical mixture in a test tube every minute, the list of temperature readings for every minute, as printed out on a spreadsheet or viewed on a computer screen are "raw data". Raw data have not been subjected to processing, "cleaning" by researchers to remove outliers, obvious instrument reading errors or data entry errors, or any analysis (e.g., determining central tendency aspects such as the average or median result). As well, raw data have not been subject to any other manipulation by a software program or a human researcher, analyst or technician. They are also referred to as ''primary'' data. Raw data is a relative term (see data), because even once raw data h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NY Magazine
''New York'' is an American biweekly magazine concerned with life, culture, politics, and style generally, and with a particular emphasis on New York City. Founded by Milton Glaser and Clay Felker in 1968 as a competitor to ''The New Yorker'', it was brasher and less polite, and established itself as a cradle of New Journalism. Over time, it became more national in scope, publishing many noteworthy articles on American culture by writers such as Tom Wolfe, Jimmy Breslin, Nora Ephron, John Heilemann, Frank Rich, and Rebecca Traister. In its 21st-century incarnation under editor-in-chief Adam Moss, "The nation's best and most-imitated city magazine is often not about the city—at least not in the overcrowded, traffic-clogged, five-boroughs sense", wrote then-''Washington Post'' media critic Howard Kurtz, as the magazine increasingly published political and cultural stories of national significance. Since its redesign and relaunch in 2004, the magazine has won more National Mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discover Magazine
''Discover'' is an American general audience science magazine launched in October 1980 by Time Inc. It has been owned by Kalmbach Publishing since 2010. History Founding ''Discover'' was created primarily through the efforts of ''Time'' magazine editor Leon Jaroff. He noticed that magazine sales jumped every time the cover featured a science topic. Jaroff interpreted this as a considerable public interest in science, and in 1971, he began agitating for the creation of a science-oriented magazine. This was difficult, as a former colleague noted, because "Selling science to people who graduated to be managers was very difficult".Hevesi, Dennis"Leon Jaroff, Editor at Time and Discover Magazines, Dies at 85" ''The New York Times'', 21 October 2012 Jaroff's persistence finally paid off, and ''Discover'' magazine published its first edition in 1980. ''Discover'' was originally launched into a burgeoning market for science magazines aimed at educated non-professionals, intended to ...

Noise (signal Processing)
In signal processing, noise is a general term for unwanted (and, in general, unknown) modifications that a signal may suffer during capture, storage, transmission, processing, or conversion. Vyacheslav Tuzlukov (2010), ''Signal Processing Noise'', Electrical Engineering and Applied Signal Processing Series, CRC Press. 688 pages. Sometimes the word is also used to mean signals that are random ( unpredictable) and carry no useful information; even if they are not interfering with other signals or may have been introduced intentionally, as in comfort noise. Noise reduction, the recovery of the original signal from the noise-corrupted one, is a very common goal in the design of signal processing systems, especially filters. The mathematical limits for noise removal are set by information theory. Types of noise Signal processing noise can be classified by its statistical properties (sometimes called the "color" of the noise) and by how it modifies the intended signal: * A ...

Normal Distribution
In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is : f(x) = \frac e^ The parameter \mu is the mean or expectation of the distribution (and also its median and mode), while the parameter \sigma is its standard deviation. The variance of the distribution is \sigma^2. A random variable with a Gaussian distribution is said to be normally distributed, and is called a normal deviate. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Their importance is partly due to the central limit theorem. It states that, under some conditions, the average of many samples (observations) of a random variable with finite mean and variance is itself a random variable—whose distribution converges to a normal dist ...
