Positive And Negative
In mathematics, the sign of a real number is its property of being either positive, negative number, negative, or 0. Depending on local conventions, zero may be considered as having its own unique sign, having no sign, or having both positive and negative sign. In some contexts, it makes sense to distinguish between signed zero, a positive and a negative zero. In mathematics and physics, the phrase "change of sign" is associated with exchanging an object for its additive inverse (multiplication with −1, negation), an operation which is not restricted to real numbers. It applies among other objects to vectors, matrices, and complex numbers, which are not prescribed to be only either positive, negative, or zero. The word "sign" is also often used to indicate binary aspects of mathematical or scientific objects, such as odd and even (Parity of a permutation, sign of a permutation), sense of Orientation (vector space), orientation or rotation (clockwise, cw/ccw), one sided limits, ...

Positive And Negative Affect Schedule
The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that consists of two 10-item scales to measure both positive and negative affect. Each item is rated on a 5-point verbal frequency scale of 1 ''(not at all)'' to 5 ''(very much)''. The measure has been used mainly as a research tool in group studies, but can be utilized within clinical and non-clinical populations as well. Shortened, elongated, and children's versions of the PANAS have been developed, taking approximately 5–10 minutes to complete. Clinical and non-clinical studies have found the PANAS to be a reliable and valid instrument in the assessment of positive and negative affect. Development and history The PANAS was developed in 1988 by researchers from the University of Minnesota and Southern Methodist University. Previous mood measures have shown correlations of variable strength between positive and negative affect, and these same measures have questionable reliability and validity. ...

Positive And Negative Sign (astrology)
In Western astrology, astrological signs are the twelve 30-degree sectors that make up Earth's 360-degree orbit around the Sun. The signs enumerate from the first day of spring, known as the First Point of Aries, which is the vernal equinox. The astrological signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The Western zodiac originated in Babylonian astrology, and was later influenced by the Hellenistic culture. Each sign was named after a constellation the sun annually moved through while crossing the sky. This observation is emphasized in the simplified and popular sun sign astrology. Over the centuries, Western astrology's zodiacal divisions have shifted out of alignment with the constellations they were named after by axial precession of the Earth while Hindu astrology measurements correct for this shifting. Astrology (i.e. a system of omina based on celestial appearances) was developed in Chinese and Ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positvity/negativity Ratio
The critical positivity ratio (also known as the "Losada ratio" or the "Losada line") is a largely discredited concept in positive psychology positing an exact ratio of positive to negative emotions which distinguishes "flourishing" people from "languishing" people. The ratio was proposed by psychologists Barbara Fredrickson and Marcial Losada, who believed that they had identified an experimental measure of affect whose model-derived positive-to-negative ratio of 2.9013 defined a critical separation between flourishing and languishing individuals, as reported in their 2005 paper in ''American Psychologist''. This concept of a critical positivity ratio was widely embraced by academic psychologists and the lay public; Fredrickson and Losada's paper had been cited more than 320 times by January 2014,Will Wilkinson, writing for ''The Daily Beast'', see citation following, states that Fredrickson & Losada (2005) "garnered almost 1,000 citations in less than a decade", which places it ...
