Photo Tampering Throughout History - 1 views

  • Photo Tampering Throughout History Photography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services). circa 1860: This nearly iconic portrait of U.S. President Abraham Lincoln is a composite of Lincoln's head and the Southern politician John Calhoun's body. Putting the date of this image into context, note that the first permanent photographic image was created in 1826 and the Eastman Dry Plate Company (later to become Eastman Kodak) was created in 1881. circa 1865: In this photo by famed photographer Mathew Brady, General Sherman is seen posing with his Generals. General Francis P. Blair (far right) was added to the original photograph.

Digital History Project hub site for historians - 28 views

  •  
    Digital history is an emerging and rapidly changing academic field. The purpose of the Digital History Project is to educate scholars and the public about the state of the discipline by providing access to: interviews with scholars about topics related to digital history; presentations and essays about the field by noted scholars; syllabi and student projects from courses in digital history; reviews of major online projects and of tools which may be of use to digital historians; indices of peer-reviewed scholarship and digital projects; a directory of historians practicing digital history; and a clearinghouse of current events and news items of interest. Partners The site is made available through the generous support of the John and Catherine Angle Fund. It received production assistance from the New Media Center at the University of Nebraska-Lincoln. This site is maintained by Douglas Seefeldt, Assistant Professor of History & Faculty Fellow, Center for Digital Research in the Humanities, and William G. Thomas, III, John and Catherine Angle Chair in the Humanities and Professor of History, both of the University of Nebraska-Lincoln.

      Start of Civil War
  • In response to the election of Abraham Lincoln as President of the United States, 11 southern slave states declared their secession from the United States and formed the Confederate States of America
  • n April 1861, Lincoln announced the Union blockade of all Southern ports; commercial ships could not get insurance and regular traffic ended. The South blundered in embargoing cotton exports in 1861 before the blockade was effective; by the time they realized the mistake it was too late. "King Cotton" was dead, as the South could export less than 10% of its cotton.[134]

Siri's Inventors Are Building a Radical New AI That Does Anything You Ask | Enterprise ... - 13 views

  • Whereas Siri can only perform tasks that Apple engineers explicitly implement, this new program, they say, will be able to teach itself, giving it almost limitless capabilities.
  • But Kittlaus points out that all of these services are strictly limited. Cheyer elaborates: “Google Now has a huge knowledge graph—you can ask questions like ‘Where was Abraham Lincoln born?’ And it can name the city. You can also say, ‘What is the population?’ of a city and it’ll bring up a chart and answer. But you cannot say, ‘What is the population of the city where Abraham Lincoln was born?’” The system may have the data for both these components, but it has no ability to put them together, either to answer a query or to make a smart suggestion. Like Siri, it can’t do anything that coders haven’t explicitly programmed it to do.

An Introduction to Inquiry-Based Learning - 122 views

  •  
    "What kinds of questions make for good inquiry-based projects? As we said, they must first be questions that the kids truly care about because they come up with them themselves. In addition, good questions share the following characteristics: The questions must be answerable. "What is the poem 'Dream Deferred' based on?" is answerable. "Why did Langston Hughes write it?" may be answerable if such information exists, or if the students have some relevant and defensible opinions. "Why did he choose this particular word in line six?" is not answerable because the only person likely to know such a specific answer is Hughes himself, now deceased. The answer cannot be a simple fact. "In what year was Lincoln killed?" doesn't make for a very compelling project because you can just look it up in any number of books or Web sites. "What factors caused the assassination attempt?" might be a good project because it will require research, interpretation, and analysis. The answer can't already be known. "What is hip-hop music?" is a bit too straightforward and the kids are not likely to learn much more than they know already. "What musical styles does hip-hop draw from and how?" offers more opportunity for exploration. The questions must have some objective basis for an answer. "Why is the sky blue?" can be answered through research. "Why did God make the sky blue?" cannot because it is a faith-based question. Both are meaningful, valid, real questions, but the latter isn't appropriate for an inquiry-based project. "What have people said about why God made the sky blue?" might be appropriate. Likewise, "Why did the dinosaurs become extinct?" is ultimately unanswerable in that form because no humans were around to know for sure, but "What do scientists believe was the reason for their extinction?" or "What does the evidence suggest about the cause?" will work. Questions based on value judgments don't work for similar reasons. You can't objectively answer "Is Hamle

Biography in Context - Document - 16 views

  • The outbreak of the war changed Emerson, who had disdained political parties, mistrusted philanthropic efforts, and once called himself "a seeing eye, not a helping hand." He labeled the war "a new glass to see all our old things through." It was "instructor," "searcher" "magnetizer" and "reconciler." Emerson the individualist and idealist may have bristled at the churning power of the machinery of war, but Emerson the patriot and realist welcomed the struggle for the birth of a new social order. "The War," Emerson realized, "is serving many good purposes .... War shatters everything flimsy and shifty, sets aside all false issues, and breaks through all that is not real as itself."
