🔗 Psychology

In psychology, the four stages of competence, or the "conscious competence" learning model, relates to the psychological states involved in the process of progressing from incompetence to competence in a skill. People may have several skills, some unrelated to each other, and each skill will typically be at one of the stages at a given time. Many skills require practice to remain at a high level of competence.

The four stages suggest that individuals are initially unaware of how little they know, or unconscious of their incompetence. As they recognize their incompetence, they consciously acquire a skill, then consciously use it. Eventually, the skill can be utilized without it being consciously thought through: the individual is said to have then acquired unconscious competence.

Operation Snow White was a criminal conspiracy by the Church of Scientology during the 1970s to purge unfavorable records about Scientology and its founder, L. Ron Hubbard. This project included a series of infiltrations into and thefts from 136 government agencies, foreign embassies and consulates, as well as private organizations critical of Scientology, carried out by Church members in more than 30 countries. It was one of the largest infiltrations of the United States government in history, with up to 5,000 covert agents. This operation also exposed the Scientology plot "Operation Freakout", because Operation Snow White was the case that initiated the U.S. government's investigation of the Church.

Under this program, Scientology operatives committed infiltration, wiretapping, and theft of documents in government offices, most notably those of the U.S. Internal Revenue Service. Eleven highly placed Church executives, including Mary Sue Hubbard (third wife of founder L. Ron Hubbard and second-in-command of the organization), pleaded guilty and were convicted in federal court of obstructing justice, burglary of government offices, and theft of documents and government property. The case was United States v. Mary Sue Hubbard et al., 493 F.Supp. 209 (D.D.C. 1979).

Pain in babies, and whether babies feel pain, has been a large subject of debate within the medical profession for centuries. Prior to the late nineteenth century it was generally considered that babies hurt more easily than adults. It was only in the last quarter of the 20th century that scientific techniques finally established babies definitely do experience pain – probably more than adults – and developed reliable means of assessing and of treating it. As recently as 1999, it was commonly stated that babies could not feel pain until they were a year old, but today it is believed newborns and likely even fetuses beyond a certain age can experience pain.

A road diet (also called a lane reduction, road rechannelization or road conversion) is a technique in transportation planning whereby the number and/or the width of travel lanes of the road is reduced, often to achieve a reduction in crash rates.

The Pick operating system (often called just "the Pick system" or simply "Pick") is a demand-paged, multiuser, virtual memory, time-sharing computer operating system based around a unique MultiValue database. Pick is used primarily for business data processing. It is named after one of its developers, Dick Pick.

The term "Pick system" has also come to be used as the general name of all operating environments which employ this multivalued database and have some implementation of Pick/BASIC and ENGLISH/Access queries. Although Pick started on a variety of minicomputers, the system and its various implementations eventually spread to a large assortment of microcomputers, personal computers and mainframe computers.

Julian Jaynes (February 27, 1920 – November 21, 1997) was an American researcher in psychology at Yale and Princeton for nearly 25 years and best known for his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind. His career was dedicated to the problem of consciousness, “…the difference between what others see of us and our sense of our inner selves and the deep feelings that sustain it. … Men have been conscious of the problem of consciousness almost since consciousness began.” Jaynes's solution touches on many disciplines, including neuroscience, linguistics, psychology, archeology, history, religion and analysis of ancient texts.

Spaced repetition is an evidence-based learning technique that is usually performed with flashcards. Newly introduced and more difficult flashcards are shown more frequently while older and less difficult flashcards are shown less frequently in order to exploit the psychological spacing effect. The use of spaced repetition has been shown to increase rate of learning.

Although the principle is useful in many contexts, spaced repetition is commonly applied in contexts in which a learner must acquire many items and retain them indefinitely in memory. It is, therefore, well suited for the problem of vocabulary acquisition in the course of second-language learning. A number of spaced repetition software programs have been developed to aid the learning process. Alternative names for spaced repetition include spaced rehearsal, expanding rehearsal, graduated intervals, repetition spacing, repetition scheduling, spaced retrieval and expanded retrieval.

🔗 Food and drink 🔗 Brands

Metrecal was a brand of diet foods introduced in the early 1960s. Though its products were criticized for their taste, which newer varieties of flavor tried to improve upon later, it attained a niche in the popular culture of the time. Created and marketed initially by C. Joseph Genster of Mead Johnson & Company, it was eventually replaced in the market by competitors such as SlimFast and lost popularity because it was linked to deaths.
