Persona (psychology)

The persona, for Swiss psychiatrist Carl Jung, was the social face the individual presented to the world—"a kind of mask, designed on the one hand to make a definite impression upon others, and on the other to conceal the true nature of the individual".

Jung’s persona

Identification

The development of a viable social persona is a vital part of adapting to, and preparing for, adult life in the external social world. “A strong ego relates to the outside world through a flexible persona; identification with a specific persona (doctor, scholar, artist, etc.) inhibits psychological development. Thus for Jung “the danger is that [people] become identical with their personas—the professor with his textbook, the tenor with his voice.” The result could be “the shallow, brittle, conformist kind of personality which is 'all persona', with its excessive concern for 'what people think'”—an unreflecting state of mind 'in which people are utterly unconscious of any distinction between themselves and the world in which they live. They have little or no concept of themselves as beings distinct from what society expects of them'. The stage was set thereby for what Jung termed enantiodromia—the emergence of the repressed individuality from beneath the persona later in life: 'the individual will either be completely smothered under an empty persona or an enantiodromia into the buried opposites will occur'.

Persona (user experience)

In user-centered design and marketing, personas are fictional characters created to represent the different user types that might use a site, brand, or product in a similar way. Marketers may use personas together with market segmentation, where the qualitative personas are constructed to be representative of specific segments. The term persona is used widely in online and technology applications as well as in advertising, where other terms such as pen portraits may also be used.

Personas are useful in considering the goals, desires, and limitations of brand buyers and users in order to help to guide decisions about a service, product or interaction space such as features, interactions, and visual design of a website. Personas may also be used as part of a user-centered design process for designing software and are also considered a part of interaction design (IxD), having been used in industrial design and more recently for online marketing purposes.

A user persona is a representation of the goals and behavior of a hypothesized group of users. In most cases, personas are synthesized from data collected from interviews with users. They are captured in 1–2-page descriptions that include behavior patterns, goals, skills, attitudes, and the environment, with a few fictional personal details to make the persona a realistic character. For each product, more than one persona is usually created, but one persona should always be the primary focus for the design.

Persona (1966 film)

Persona is a 1966 black and white Swedish film written and directed by Ingmar Bergman and starring Bibi Andersson and Liv Ullmann. Persona’s story revolves around a young nurse named Alma (Bibi Andersson) and her patient, a well-known stage actress named Elisabet Vogler (Liv Ullmann), who has suddenly ceased to speak. The Latin word persona originally referred to the masks worn by actors on stage.

Persona has been labelled a psychological drama and modernist horror, and was subject to cuts because of its controversial subject matter. It is the sixth collaboration between influential cinematographer Sven Nykvist and director Ingmar Bergman and features their trademark minimalism. As with Bergman’s other works, the film is shot and set in Sweden and deals with the themes of illness, bleakness, death and insanity.

Persona is considered one of the major works of the 20th century by essayists and critics such as Susan Sontag who referred to it as Bergman's masterpiece. Other critics have described it as "one of this century’s great works of art". In the British Film Institute's 2012 Sight & Sound’s poll, Persona was ranked the 17th greatest film ever made in the critics' poll (tied with Akira Kurosawa's "Seven Samurai") and 13th in the directors' poll. Persona won the award for Best Film at the 4th Guldbagge Awards and it was Sweden's entry to the 39th Academy Award category for Best Foreign Film. It currently holds a 93% "Fresh" rating at Rotten Tomatoes.

Film (film)

Film is a 1965 film written by Samuel Beckett, his only screenplay. It was commissioned by Barney Rosset of Grove Press. Writing began on 5 April 1963 with a first draft completed within four days. A second draft was produced by 22 May and a forty-leaf shooting script followed thereafter. It was filmed in New York in July 1964.

Beckett’s original choice for the lead – referred to only as “O” – was Charlie Chaplin, but his script never reached him. Both Beckett and the director Alan Schneider were interested in Zero Mostel and Jack MacGowran. However, the former was unavailable and the latter, who accepted at first, became unavailable due to his role in a "Hollywood epic." Beckett then suggested Buster Keaton. Schneider promptly flew to Los Angeles and persuaded Keaton to accept the role along with "a handsome fee for less than three weeks' work."James Karen, who was to have a small part in the film, also encouraged Schneider to contact Keaton.

The filmed version differs from Beckett's original script but with his approval since he was on set all the time, this being his only visit to the United States. The script printed in Collected Shorter Plays of Samuel Beckett (Faber and Faber, 1984) states:

Lubrication theory

In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer beneath the puck is much smaller than the dimensions of the puck itself.

Internal flows are those where the fluid is fully bounded. Internal flow lubrication theory has many industrial applications because of its role in the design of fluid bearings. Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant.

Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case the position of the free surface is itself unknown, and one goal of lubrication theory is then to determine this. Surface tension may then be significant, or even dominant. Issues of wetting and dewetting then arise. For very thin films (thickness less than one micrometre), additional intermolecular forces, such as Van der Waals forces or disjoining forces, may become significant.
