Blumberg sign

(noun)

Blumberg's sign is a sign that is elicited during physical examination in medicine and is indicative of peritonitis. A positive sign shows rebound tenderness, meaning that pressing a hand on the abdomen elicits less pain than releasing the hand abruptly, which will aggravate the pain, as the peritoneum snaps back into place.

  • Statistical Literacy

    • This webpage gives the FBI list of warning signs for school shooters: http://news.bbc.co.uk/2/hi/americas/1205252.stm.
    • Do you think it is likely that someone showing a majority of these signs would actually shoot people in school?
    • The warning signs are unlikely to be sufficiently predictive to warrant the conclusion that a student will become a shooter.
    • If an action is taken on the basis of these warning signs, it is likely that the student involved would never have become a shooter even without the action.

  • Sign Test

    • The sign test can be used to test the hypothesis that there is "no difference in medians" between the continuous distributions of two random variables.
    • One such statistical method is known as the sign test.
    • As outlined above, the sign test is a non-parametric test which makes very few assumptions about the nature of the distributions under examination.
    • The test statistic $x$ is then the number of plus signs.
    • The sign test involves denoting values above the median of a continuous population with a plus sign and the ones falling below the median with a minus sign in order to test the hypothesis that there is no difference in medians.

  • The Rule of Signs

    • We can see that the negative signs cancel out for any even power.
    • This function has one sign change between the second and third terms.
    • We know that the number of roots of either sign is the number of sign changes, or a multiple of two less than that.
    • To find the positive roots we count the sign changes.
    • Since there are no sign changes, there are no positive roots $(p=0)$.

  • Higher Education

    • It was signed into law on April 11, 1965, less than three months after it was introduced.
    • The Higher Education Facilities Act of 1963, which was signed into law by Johnson a month after he became president, authorized a dramatic increase in college aid within a five-year period and provided better college libraries, 10-20 new graduate centers, several new technical institutes, classrooms for several hundred thousand students, and 25-30 new community colleges each year.
    • This major piece of legislation was followed by the Higher Education Act of 1965, signed into United States law on November 8, 1965 at Texas State University.
    • This signing plaque rests on campus grounds of Texas State University commemorating the Higher Education Act.

  • Introduction to Blood Pressure

    • Blood pressure is a vital sign reflecting the pressure exerted on blood vessels when blood is forced out of the heart during contraction.
    • Blood pressure is one of the principal vital signs.
    • Blood pressure and pulse, or the vital signs, are measured as indicators of several aspects of cardiovascular health.

  • Language

    • Another definition sees language as a formal system of signs governed by grammatical rules of combination to communicate meaning.
    • This definition stresses the fact that human languages can be described as closed structural systems consisting of rules that relate particular signs to particular meanings.
    • When described as a system of symbolic communication, language is traditionally seen as consisting of three parts: signs, meanings, and a code connecting signs with their meanings.
    • The study of how signs and meanings are combined, used, and interpreted is called semiotics.

  • Cofactors, Minors, and Further Determinants

    • The cofactor of an entry $(i,j)$ of a matrix $A$ is the signed minor of that matrix.
    • Specifically the cofactor of the $(i,j)$ entry of a matrix, also known as the $(i,j)$ cofactor of that matrix, is the signed minor of that entry.
    • To know what the signed minor is, we need to know what the minor of a matrix is.
    • The determinant of any matrix can be found using its signed minors.
    • The determinant is the sum of the signed minors of any row or column of the matrix scaled by the elements in that row or column.
