Catalyst (think tank)

Catalyst (later Catalyst Forum) was an independent left wing think tank based in London, United Kingdom, set up in 1998 to promote policies directed to the redistribution of power, wealth and opportunity. Though not aligned to any political party, it was generally sympathetic to the Labour Movement and described itself as "an organisation of the left".

The organisation was founded at the high point of Tony Blair's modernisation of the Labour Party and struggled to attract funding, especially from the trades unions who had originally been expected to be the most sympathetic to its redistributionist platform. Trades unions, concerned at further exclusion from power either by the electorate or the new Labour Party leadership, took a sharp turn away from too deep an association with the Left at this time and only begun in 2005 and 2006 to develop an increased if cautious interest in left-wing thought as a new generation of activist trades union leaders has emerged.

Former right wing but egalitarian Deputy Leader of the Labour Party, Roy Hattersley, was an early supporter, as was John Edmonds, General Secretary of the GMB Union.

However, Catalyst was never a political or campaigning organisation and restricted itself to public policy work on redistribution and looking at soft areas like identity politics and public administration that were often neglected on the Left in favour of economics and social policy. It was never associated with the so-called Hard Left.

Catalyst's first Director was former Director of Policy at the Labour Party, Roland Wales, who was followed by Barbara Gunnell, Martin McIvor, and Jenny Smith. Its Founding Board of Management included Marjorie Thompson, Mark Seddon, Mike Watts, Nyta Mann, Pat Coyne, Tim Pendry, Hilary Wainwright, Richard Stone and others, with a prestigious Advisory Board. Its lack of funds did not stop it from putting out a series of pamphlets, some of which proved contentious including Simon Partridge's revisionist view of nationalism which was avowedly "Left- Burkean" and it adopted creatively low cost ways of making itself known. Its Annual Reception became a high point for centre-left political exiles from within the Labour Movement to meet and catch up.

It not only survived the modernisation period but re-emerged strengthened in recent years with a new generation of academics and intellectuals prepared to develop alternative democratic socialist policies. In 2003 Catalyst won the "One To Watch" category at Prospect magazine's annual Think Tank Awards 1. In 2006 it merged with the Compass organisation 2.

Catalyst (software)

Catalyst is an open source web application framework written in Perl, that closely follows the model–view–controller (MVC) architecture, and supports a number of experimental web patterns. It is written using Moose, a modern object system for Perl. Its design is heavily inspired by such frameworks as Ruby on Rails, Maypole, and Spring.

A web application developer would use Catalyst to deal with code common to all web applications: it provides interfaces to web servers and receiving page requests, dispatching these into developer-written code to process and return the requests, and provides a standardised interface for data models, authentication, session management and other common web application elements.

All of these elements are implemented as plugins to a set of common interfaces, allowing the developer to change the specific method used (e.g. a session storing in shared memory versus as a database table, or using FastCGI versus operating as an within Apache's mod_perl) by changing the configuration of Catalyst to use a different plugin without altering the application code.

Catalyst is primarily distributed through the CPAN, which is the official distribution channel for Perl libraries and applications.

Catalyst (magazine)

Catalyst is a student magazine published at the Royal Melbourne Institute of Technology in Melbourne, Australia. The magazine is produced by the RMIT Student Union.

Catalyst is published six times a year and had a readership of approximately 58,000 in 2009 - up from 15,000 in 2004. The implementation of voluntary student unionism in 2006 had a significant impact on the viability of student newspapers across Australia, compulsory student union membership fees having been the major source of income for most. Today, Catalyst's funding is drawn jointly from the university and advertising revenue.

Catalyst benefits from its proximity to the RMIT School of Media and Communication, which runs a highly regarded journalism program. In turn Catalyst alumni are active in the Australian media.

Notable former editors of Catalyst include journalists Dewi Cooke, Dan Harrison (both now with The Age), Patricia Karvelas of The Australian and Elizabeth Gallagher.

The first edition of Catalyst, published by what was known then as the RMIT Students’ Representative Council (later RMIT Student Union) appeared on 18 May 1944. Editions have also appeared under the names Revolution Catalyst and The Unaustralian.

In 2014 Catalyst established it's podcast Cataclysm (released tri-weekly) with each episode centring around a theme. Previous podcast themes have included animals, the body and secrets. Each episode of Cataclysm also includes a series of regular segments alongside the themed feature stories.

Mid-2015 saw one of Cataclysm's popular segments 'Politics on the Couch' spawn a webseries collaboration between Catalyst and RMITV entitled 'Politics at the Belleville'. The program is hosted by the same talent as the podcast segment and released every Friday afternoon.

Catalyst (band)

Catalyst was a funk/ jazz quartet from Philadelphia, Pennsylvania, whose material presaged the work of later jazz fusion artists. The group encountered regional success in the 1970s and have become more widely known since the re-release of their material on CD.

The group was discovered by producer Skip Drinkwater, who signed them to Muse Records after hearing them play at a club in West Philadelphia. Drinkwater and Dennis Wilen produced their debut self-titled LP, released in 1972 with the following personnel: Eddie Green (keyboards, vocals), Sherman Ferguson (percussion), Odean Pope (saxophone, flute, oboe), Alphonso Johnson (bass). The group received little label support for major tours and so spent most of their playing time in the Philadelphia and New York areas. The group recorded and released a second album in 1972 on Cobblestone Records, entitled Perception; by this time, bassist Johnson had left the group to join Weather Report, and was replaced by Tyrone Brown. Drinkwater and Wilen also produced this album.

Garnering comparisons to John Coltrane, Weather Report, and Return to Forever, a cult following had grown up around the band by this time, who returned in 1974 with Unity, again on Muse. The album featured Billy Hart in addition to its core members. 1975's After a Tear and a Smile would be the group's final release; poor album sales and disenchantment with the industry led the group to disband in 1976.

Following their time with Catalyst, Green played with Pat Martino and MFSB, and both Pope and Brown began playing gigs with Max Roach; Pope also played with the Saxophone Choir. Ferguson later played with Pharoah Sanders, Bud Shank, and Kenny Burrell.

In the 1990s, the Muse catalog was acquired by Joel Dorn's 32 Jazz label, which released some of Catalyst's work on a 1998 compilation album. Fan interest led to their entire four-album discography being released as a 2-CD set, entitled The Funkiest Band You Never Heard.

"Ain't it the Truth" and "Ile Ife" were covered by Uri Caine (keyboards), A.Thompson (Drums, from The Roots), and Christian McBride (bass), on their album " The Philadelphia Experiment".

Catalyst (building)

Catalyst is a 27-story 462-unit apartment building on West Martin Luther King Jr. Boulevard in Charlotte, North Carolina. The concrete and glass skyscraper in Third Ward, designed by Smallwood, Reynolds, Stewart, Stewart, was built by Atlanta-based Novare Group and completed in 2009.

Tony Skillbeck, president of Novare Carolinas Development, said that the name reflected the building's status as "a literal catalyst for the red-development and the regeneration of Third Ward" as well as the fact that for many residents, this would be their first home purchase, "a catalyst in our buyers' lives."

Groundbreaking took place August 29, 2007. A 15-story, office building called 440 South Church was built next door by Trinity Capital Advisors, designed by the same architectural firm. Novare was involved with the office tower, which has Ally Financial as a major tenant. However, Novare was dropped as an operating partner, though keeping its investment, because the company had significant debts that could result in foreclosures, and auditor Deloitte had "substantial doubt about the company’s ability to continue as a going concern." Novare's problems had little effect on the Catalyst project, however.

In February 2009, half the Catalyst units changed from condominiums to apartments due to the decline in the condominium market. As of September 18, 2009, one hundred people lived in the building, and about half the units were leased. As of January 2013, the building is 98% occupied with renters.

Novare managed Catalyst for "an investment fund controlled by affiliates of Lehman Brothers Holdings" with which the developer "restructured its relationship" in Summer 2009. Novare still owned the land and was building a parking lot.

C and J Catalyst bought the Catalyst in 2011 for $103.3 million, or $223,500 per unit. The building was managed by John Joyce.

Northwood Ravin LLC currently manages the building for owner C and J Catalyst LLC.

Catalyst's first floor contains 19,792 SF of retail space and is leased by Hawthorne Retail Partners.

Catalyst (nonprofit organization)

Catalyst, Inc. is a nonprofit organization that promotes inclusive workplaces for women. It was founded in 1962 by feminist, writer, and advocate Felice Schwartz. Sheila Wellington served as president of Catalyst following Schwartz for ten years. Ilene Lang has been serving as Catalyst's president since 2003.

Catalyst publishes an annual census of women in management and on corporate boards of Fortune 500 and Financial Post 500 companies. In 2010, the organization published a study in the Harvard Business Review, which found that women with MBA degrees earned an average of $4,600 less than men in their first job, even with the same amount of previous work experience. The organization also worked with the U.S. Government Accountability Office to analyze the small growth of women in management positions.
