The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
Thus, a "positive" result indicates the healthy state, in contrast to many other medical tests. Therefore, some prefer to avoid using the terms "positive" or "negative", and simply state if the test was normal or abnormal. For example: "Rinne's test was abnormal in the right ear, with bone conduction greater than air conduction".
The Kraus–Weber test (or K–W test [1]) is a fitness test devised in the 1940s by Hans Kraus and Sonja Weber of New York Presbyterian Hospital. The poor tests results of American children versus children from European countries gained attention in the 1950s from American media, prompting the United States government to establish the Presidential Fitness Test within the following decades.
Ideal type (German: Idealtypus), also known as pure type, is a typological term most closely associated with the sociologist Max Weber (1864–1920). [1] For Weber, the conduct of social science depends upon the construction of abstract, hypothetical concepts.
The Weber number is the dimensionless parameter that determines the onset of this phenomenon called the entrainment limit (Weber number greater than or equal to 1). In this case the Weber number is defined as the ratio of the momentum in the vapor layer divided by the surface tension force restraining the liquid, where the characteristic length ...

For many sensory modalities, over a wide range of stimulus magnitudes sufficiently far from the upper and lower limits of perception, the 'JND' is a fixed proportion of the reference sensory level, and so the ratio of the JND/reference is roughly constant (that is the JND is a constant proportion/percentage of the reference level).
Weber also noted that life chances are to certain extent subjective: one's assessment of one's life chances will affect one's actions; therefore, if one believes that one is or can become a respected and valued member of society, that outcome and associated positive results are more likely to become a reality for such a person than they are for ...
