🔗 Psychology

The need for cognition (NFC), in psychology, is a personality variable reflecting the extent to which individuals are inclined towards effortful cognitive activities.

Need for cognition has been variously defined as "a need to structure relevant situations in meaningful, integrated ways" and "a need to understand and make reasonable the experiential world". Higher NFC is associated with increased appreciation of debate, idea evaluation, and problem solving. Those with a high need for cognition may be inclined towards high elaboration. Those with a lower need for cognition may display opposite tendencies, and may process information more heuristically, often through low elaboration.

Need for cognition is closely related to the five factor model domain openness to experience, typical intellectual engagement, and epistemic curiosity (see below).

Abnormal behavior of birds in captivity has been found to occur among both domesticated and wild birds. Abnormal behavior can be defined in several ways. Statistically, 'abnormal' is when the occurrence, frequency or intensity of a behaviour varies statistically significantly, either more or less, from the normal value. This means that theoretically, almost any behaviour could become 'abnormal' in an individual. Less formally, 'abnormal' includes any activity judged to be outside the normal behaviour pattern for captive birds of that particular class or age. For example, running rather than flying may be a normal behaviour and regularly observed in one species, however, in another species it might be normal but becomes 'abnormal' if it reaches a high frequency, or in another species it is rarely observed and any incidence is considered 'abnormal'. This article does not include 'one-off' behaviours performed by individual birds that might be considered abnormal for that individual, unless these are performed repeatedly by other individuals in the species and are recognised as part of the ethogram of that species.

Most abnormal behaviours can be categorised collectively (e.g., eliminative, ingestive, stereotypies), however, many abnormal behaviours fall debatably into several of these categories and categorisation is therefore not attempted in this article. Abnormal behaviours here are considered to be related to captive housing but may also be due to medical conditions. The article does not include behaviours in birds that are genetically modified to express abnormal behaviour.

A holon (Greek: ὅλον, from ὅλος, holos, 'whole' and -ον, -on, 'part') is something that is simultaneously a whole in and of itself, as well as a part of a larger whole. In other words, holons can be understood as the constituent part–wholes of a hierarchy.

The holon represents a way to overcome the dichotomy between parts and wholes, as well as a way to account for both the self-assertive and the integrative tendencies of organisms. The term was coined by Arthur Koestler in The Ghost in the Machine (1967). In Koestler's formulations, a holon is something that has integrity and identity while simultaneously being a part of a larger system; it is a subsystem of a greater system.

Holons are sometimes discussed in the context of self-organizing holarchic open (SOHO) systems.

Mono no aware (物の哀れ), literally "the pathos of things", and also translated as "an empathy toward things", or "a sensitivity to ephemera", is a Japanese idiom for the awareness of impermanence (無常, mujō), or transience of things, and both a transient gentle sadness (or wistfulness) at their passing as well as a longer, deeper gentle sadness about this state being the reality of life.

🔗 Psychology

Transactional analysis (TA) is a psychoanalytic theory and method of therapy wherein social transactions are analyzed to determine the ego state of the patient (whether parent-like, childlike, or adult-like) as a basis for understanding behavior. In transactional analysis, the patient is taught to alter the ego state as a way to solve emotional problems. The method deviates from Freudian psychoanalysis which focuses on increasing awareness of the contents of unconsciously held ideas. Eric Berne developed the concept and paradigm of transactional analysis in the late 1950s.

Linguistic purism in English is the preference for using words of native origin rather than foreign-derived ones. "Native" can mean "Anglo-Saxon" or it can be widened to include all Germanic words. Linguistic purism in English primarily focuses on words of Latinate and Greek origin, due to their prominence in the English language and the belief that they may be difficult to understand. In its mildest form, it merely means using existing native words instead of foreign-derived ones (such as using begin instead of commence). In a less mild form, it also involves coining new words from Germanic roots (such as wordstock for vocabulary). In a more extreme form, it also involves reviving native words which are no longer widely used (such as ettle for intend). The resulting language is sometimes called Anglish (coined by the author and humorist Paul Jennings), or Roots English (referring to the idea that it is a "return to the roots" of English). The mild form is often advocated as part of Plain English, but the more extreme form has been and is still a fringe movement; the latter can also be undertaken as a form of constrained writing.

English linguistic purism is discussed by David Crystal in the Cambridge Encyclopedia of the English Language. The idea dates at least to the inkhorn term controversy of the 16th and 17th centuries. In the 19th century, writers such as Charles Dickens, Thomas Hardy and William Barnes advocated linguistic purism and tried to introduce words like birdlore for ornithology and bendsome for flexible. A notable supporter in the 20th century was George Orwell, who had a preference for plain Saxon words over complex Latin or Greek ones, and the idea continues to have advocates today.

🔗 Mathematics

A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art, especially in textiles and tiles as well as wallpaper.

The simplest wallpaper group, Group p1, applies when there is no symmetry other than the fact that a pattern repeats over regular intervals in two dimensions, as shown in the section on p1 below.

Consider the following examples of patterns with more forms of symmetry:

Examples A and B have the same wallpaper group; it is called p4m in the IUC notation and *442 in the orbifold notation. Example C has a different wallpaper group, called p4g or 4*2 . The fact that A and B have the same wallpaper group means that they have the same symmetries, regardless of details of the designs, whereas C has a different set of symmetries despite any superficial similarities.

The number of symmetry groups depends on the number of dimensions in the patterns. Wallpaper groups apply to the two-dimensional case, intermediate in complexity between the simpler frieze groups and the three-dimensional space groups. Subtle differences may place similar patterns in different groups, while patterns that are very different in style, color, scale or orientation may belong to the same group.

A proof that there were only 17 distinct groups of such planar symmeries was first carried out by Evgraf Fedorov in 1891 and then derived independently by George Pólya in 1924. The proof that the list of wallpaper groups was complete only came after the much harder case of space groups had been done. The seventeen possible wallpaper groups are listed below in § The seventeen groups.

Movile Cave (Romanian: Peștera Movile) is a cave near Mangalia, Constanța County, Romania discovered in 1986 by Cristian Lascu a few kilometers from the Black Sea coast. It is notable for its unique groundwater ecosystem abundant in hydrogen sulfide and carbon dioxide, but low in oxygen. Life in the cave has been separated from the outside for the past 5.5 million years and it is based completely on chemosynthesis rather than photosynthesis.
