PRism is an open access peer-reviewed electronic academic journal published by Massey University and Bond University, covering public relations. The editor-in-chief is Elspeth Tilley (Massey University). The journal was established in 2003.
PRism ranked as a "B" journal in both the 2008 and 2010 listings of international refereed journal quality rankings issued biannually from the Australian Business Deans Council (ABDC). This means PRism is consistently and formally recognised by independent external assessment as a "well regarded journal in the field" that "publishes research of a good standard in terms of originality, significance and rigour and papers are fully refereed according to good standards and practices" (Australian Business Deans, 2008). The ABDC rankings consider such factors as "relative standing of the journal in other recognised lists (such as the Association of Business Schools), citation metrics, international standing of the editorial board, quality of peer-review processes, track record of publishing influential papers, sustained reputation, and influence of publications in the journal in relation to hiring, tenure and promotion decisions" (ABDC, 2010, p. 1).

In geometry, a prism is a polyhedron with an n-sided polygonal base, another congruent parallel base (with the same rotational orientation), and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases. All cross-sections parallel to the base faces are congruent to the bases. Prisms are named for their base, so a prism with a pentagonal base is called a pentagonal prism. The prisms are a subclass of the prismatoids.
Prism (often styled as PRiSM) is a Canadian rock band formed in Vancouver in 1977. They were originally active from 1977 to 1984 and have been active again from 1987 to present. Their classic line-up consisted of lead singer Ron Tabak, guitarist Lindsay Mitchell, keyboardist John Hall, bass guitarist Al Harlow, and drummer Rocket Norton.
The band's sound is a mix of Album-oriented rock ( AOR) and pop rock, and they have released a total of thirteen studio albums, three compilation albums, and one live album.
Prism's success has been primarily in Canada where they won the Canadian music industry Juno Award for Group of the Year in 1981, although they also reached the US top 40 charts with 1981's " Don't Let Him Know". Prism is also noteworthy for launching the careers of several former group members, including international record producer Bruce Fairbairn, songwriter Jim Vallance, Powder Blues Band frontman Tom Lavin, and Headpins and Chilliwack musician Ab Bryant. A pre-fame Bryan Adams also contributed as a songwriter to several early Prism releases.
On Sunday, March 6, 2011, Prism's "Spaceship Superstar" was chosen as the wake up song for the Space Shuttle Discovery crew members. This was a significant point in history as it was the last day that the crews of Discovery and the International Space Station were together before Discovery returned to Earth in the last mission of Discovery.
PRISM (TV network)
PRISM (Philadelphia Regional In-Home Sports and Movies) is a defunct American regional premium cable television channel in the Philadelphia, Pennsylvania metropolitan area. Launched in September 1976, PRISM was primarily distributed through area cable systems, although it was also available through a scrambled over-the-air signal on WWSG-TV (channel 57, now WPSG) from 1983 to 1985.
The channel's programming consisted primarily of theatrically released motion pictures, although it was better known for its telecasts of sporting events, particularly those featuring Philadelphia's Major League Baseball, NHL and NBA sports franchises. Due to broadcasting restrictions imposed by the three major sports leagues, as a cable channel, the network limited its distribution to within of Philadelphia proper (covering an area extending from west of Harrisburg to as far north as Scranton).
Prism (Dave Holland album)
Prism is a studio album by English jazz bassist Dave Holland. The record was released via the Dare2 label on September 2, 2013. This album is a milestone of Dave Holland’s career as a leader—the forty year anniversary of his debut, free jazz album Conference of the Birds released in 1973.

Prism is the fourth Korean mini-album by South Korean girl group Rainbow. It was released on February 15, 2016 by DSP Media.
In sedimentology, a prism is a long, narrow, wedge-shaped sedimentary body. These types of sediments are typically formed during orogenic deformation; for example, the arkose detrital sedimentary rock found in fault troughs. In mineralogy, prismatic is also type of mineral habit (appearance of a crystal). Prismatic minerals have crystals that show a uniform cross-section. Prismatic crystals typically have 3, 4, 6, 8 or 12 faces which are parallel to a crystallographic axis. The apatite group of minerals commonly exhibit elongated hexagonal prisms.

PRISM (Power Reactor Innovative Small Module, sometimes S-PRISM from SuperPRISM) is the name of a nuclear power plant design by GE Hitachi Nuclear Energy (GEH).
The S-PRISM represents GEH's Generation IV reactor solution to closing the nuclear fuel cycle and is also part of its Advanced Recycling Center (ARC) proposition to U.S. Congress to deal with nuclear waste. S-PRISM is a commercial implementation of the Integral Fast Reactor developed by Argonne National Laboratory between 1984 and 1994.
It is a sodium-cooled fast breeder reactor, based on the Experimental Breeder Reactor II (EBR-II) design, scaled up by a factor of ten.
The design utilizes reactor modules, each having a power output of 311 MWe, to enable factory fabrication at low cost.
In an identical fashion to the EBR-II that it is based on, the reactor would transition to a much lower power level whenever temperatures rise significantly, moreover the reactor vessel modules are pool type, as opposed to loop type, with the pool conferring substantial thermal inertia and the final key safety feature includes a "RVACS", which is a passive reactor vessel air cooling system to remove decay heat. These safety systems are passive and therefore always operate and are to prevent core damage when no other means of heat removal are available.
Prism (Katy Perry album)
Prism is the fourth studio album by American singer Katy Perry. It was released by Capitol Records on October 18, 2013. While the album was initially planned to be "darker" than her previous material, Prism ultimately became a prominently dance-inspired record. The singer worked with several past collaborators, while enlisting new producers and guest vocals. Much of Prism revolves around the themes of living in the present, relationships, and self-empowerment. Many critics praised the album's lyrical content for being more "mature" while others considered Prism to be more formulaic than her previous material.
The album debuted atop the US Billboard 200 with 286,000 copies sold, becoming Perry's best opening week to date. The album also peaked at number one in Australia, Canada, Ireland, New Zealand, and the United Kingdom. Prism became Perry's fastest-selling album, the second best-selling album in Australia in 2013, and the second best-selling album released by a woman in the United States in 2013. The International Federation of the Phonographic Industry (IFPI) reported that Prism was the sixth best-selling album in the world in 2013, the best-selling album in the world in 2013 released by a woman, and labeled Perry "a global phenomenon." It has globally sold 4 million copies as of August 2015. The album's success continued throughout 2014, ranking within the top 10 of the annual charts for 2014 in the United States, Canada, Australia, and New Zealand, and earned Perry a Grammy Award nomination for Best Pop Vocal Album at the 57th Annual Grammy Awards.
The release of the album was preceded by the release of two singles. " Roar" was released on August 10, 2013 as the album's lead single. It became a commercial success and topped the Billboard Hot 100. " Unconditionally" debuted on October 16, 2013 as the record's second single and was a moderate commercial success worldwide. In between the release of these two tracks were the releases of promotional singles " Dark Horse" on September 17 and " Walking on Air" on September 30, 2013. "Dark Horse" was released as the album's third single three months later on December 17, 2013, and also reached number one on the Billboard Hot 100. " Birthday" and " This Is How We Do" were the fourth and fifth singles, respectively. Prism was further promoted through The Prismatic World Tour.
PRISM (surveillance program)
PRISM is a clandestine surveillance program under which the United States National Security Agency (NSA) collects internet communications from at least nine major US internet companies. Since 2001 the United States government has increased its scope for such surveillance, and so this program was launched in 2007.
PRISM is a government code name for a data-collection effort known officially by the SIGAD . The PRISM program collects stored internet communications based on demands made to internet companies such as Google Inc. under Section 702 of the FISA Amendments Act of 2008 to turn over any data that match court-approved search terms. The NSA can use these PRISM requests to target communications that were encrypted when they traveled across the internet backbone, to focus on stored data that telecommunication filtering systems discarded earlier, and to get data that is easier to handle, among other things.
PRISM began in 2007 in the wake of the passage of the Protect America Act under the Bush Administration. The program is operated under the supervision of the U.S. Foreign Intelligence Surveillance Court (FISA Court, or FISC) pursuant to the Foreign Intelligence Surveillance Act (FISA). Its existence was leaked six years later by NSA contractor Edward Snowden, who warned that the extent of mass data collection was far greater than the public knew and included what he characterized as "dangerous" and "criminal" activities. The disclosures were published by The Guardian and The Washington Post on June 6, 2013. Subsequent documents have demonstrated a financial arrangement between NSA's Special Source Operations division (SSO) and PRISM partners in the millions of dollars.
Documents indicate that PRISM is "the number one source of raw intelligence used for NSA analytic reports", and it accounts for 91% of the NSA's internet traffic acquired under FISA section 702 authority." The leaked information came to light one day after the revelation that the FISA Court had been ordering a subsidiary of telecommunications company Verizon Communications to turn over to the NSA logs tracking all of its customers' telephone calls.
U.S. government officials have disputed some aspects of the Guardian and Washington Post stories and have defended the program by asserting it cannot be used on domestic targets without a warrant, that it has helped to prevent acts of terrorism, and that it receives independent oversight from the federal government's executive, judicial and legislative branches. On June 19, 2013, U.S. President Barack Obama, during a visit to Germany, stated that the NSA's data gathering practices constitute "a circumscribed, narrow system directed at us being able to protect our people."
Prism (Ryo Kawasaki album)
Prism is the first album recorded by Japanese musician Ryo Kawasaki after he relocated to New York City from Tokyo in Japan. He recorded additional two leader albums in Japan prior to this album. At the time of this recording, he was band member of Gil Evans Orchestra, Elvin Jones Jazz Machine, Chico Hamilton group and New York based Jazz Fusion group Tarika Blue led by keyboardist Phil Clendeninn.
As a result, musicians participated on this album are his band mates from these groups, Herb Bushler from Gil Evans Orchestra, Abdulha and Steve Turre from Chico Hamilton group and Phil Clendeninn from Tarika Blue except drummer Buddy Williams was a member of George Benson group at that time often played with Ryo Kawasaki on his local gigs in NYC. The entire album was recorded in one afternoon and mixed in the next day to be completed.
All songs composed and Arranged by Ryo Kawasaki except Track 5. -Phil- composed by Phil Clendeninn

(Crystallog.) A form the planes of which are parallel to the vertical axis. See Form, n., 13.
Achromatic prism (Opt.), a prism composed usually of two prisms of different transparent substances which have unequal dispersive powers, as two different kinds of glass, especially flint glass and crown glass, the difference of dispersive power being compensated by giving them different refracting angles, so that, when placed together so as to have opposite relative positions, a ray of light passed through them is refracted or bent into a new position, but is free from color.
Nicol's prism, Nicol prism. [So called from Wm. Nicol, of Edinburgh, who first proposed it.] (Opt.) An instrument for experiments in polarization, consisting of a rhomb of Iceland spar, which has been bisected obliquely at a certain angle, and the two parts again joined with transparent cement, so that the ordinary image produced by double refraction is thrown out of the field by total reflection from the internal cemented surface, and the extraordinary, or polarized, image alone is transmitted.
