Case Control Studies

Famous quotes containing the words case, control and/or studies:

    The circumstances with which every thing in this world is begirt, give every thing in this world its size and shape;—and by tightening it, or relaxing it, this way or that, make the thing to be, what it is—great—little—good—bad—indifferent or not indifferent, just as the case happens.
    Laurence Sterne (1713–1768)

    The child knows only that he engages in play because it is enjoyable. He isn’t aware of his need to play—a need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.
    Bruno Bettelheim (20th century)

    These studies which stimulate the young, divert the old, are an ornament in prosperity and a refuge and comfort in adversity; they delight us at home, are no impediment in public life, keep us company at night, in our travels, and whenever we retire to the country.
    Marcus Tullius Cicero (106–43 B.C.)
