Steel-string acoustic guitar

The steel-string acoustic guitar is a modern form of guitar that descends from the nylon-strung classical guitar, but is strung with steel strings for a brighter, louder sound. Like the classical guitar, it is referred to as an acoustic guitar; the most common type is called a flat top guitar, to distinguish it from the more specialized archtop guitar and other variations. The standard tuning for an acoustic guitar is E-A-D-G-B-E, although many players fingerpickers, use alternate tunings, such as open G, open D, or drop D. Steel-string guitars vary in construction and materials. Different woods and approach to bracing affect the instrument's tone. While there is little scientific evidence, many players and luthiers believe a well-made guitar's tone improves over time, they theorize that a decrease in the content of hemicellulose, crystallization of cellulose, changes to lignin over time all result in its wood gaining better resonating properties. Steel-string acoustic guitars are constructed in several body types, varying in size and proportion.

In general, the guitar's soundbox can be thought of as composed of two mating chambers: the upper bouts on the neck end of the body, lower bouts. These meet at the narrowest part of the body face near the soundhole; the proportion and overall size of these two parts helps determine the overall tonal balance and "native sound" of a particular body style – the larger the body, the louder the volume. The 00, double-O or grand concert body type is the major body style most directly derived from the classical guitar, it has the thinnest soundbox and the smallest overall size, making it comfortable to play but lacking in projection -volume - relative to the larger types. Its smaller size makes it suitable for smaller-framed players, it is called a "parlor steel", as it is well-suited to smaller rooms. Martin's 00-xxx series and Taylor's x12 series are common examples; the grand auditorium guitar, sometimes called the 000 or the triple-O is similar in design to the grand concert, but wider and deeper.

Many 000-style guitars have a convex back to increase the physical volume of the soundbox without making it deeper at the edges, which would affect comfort and playability. The result is a balanced tone, comparable to the 00 but with greater volume and dynamic range and more low-end response, making this Classically shaped body style popular. Eric Clapton's signature Martin, for example, is of this style. Martin's 000-xxx series and Taylor's x14 series are well-known examples of the grand auditorium style; the dreadnought is a large-bodied guitar which incorporates a deeper soundbox, but a smaller and less-pronounced upper bout than most styles. Its size and power gave rise to its name, from the most formidable class of warship at the time of its creation in the early 20th century; the style was designed by Martin Guitars to produce a deeper sound than "classic"-style guitars, with resonant bass. Its body's combination of compact profile with a deep sound has since been copied by every major steel-string luthier, making it the most popular body type.

Martin's "D" series guitars, such as the prized D-28, are classic examples of the dreadnought. The jumbo body type is bigger again than a grand auditorium but proportioned, is designed to provide a deep tone similar to a dreadnought's, it was designed by Gibson to compete with the dreadnought,) but with maximum resonant space for greater volume and sustain. These come at the expense of being oversized, with a deep sounding box, thus somewhat more difficult to play; the foremost example of the style is the Gibson J-200, but like the dreadnought, most guitar manufacturers have at least one jumbo model. Any of these body type can incorporate a cutaway, where a section of the upper Below the neck is scalloped out; this allows for easier access to the frets located atop the soundbox, at the expense of reduced soundbox volume and altered bracing, which can affect the resonant qualities and resulting tone of the instrument. The 12-string guitar replaces each string with a course of two strings; the lower pairs are tuned an octave apart.

Its unique sound was made famous by artists such as Pete Seeger and Leo Kottke. All of these traditional looking and constructed instruments are referred to as flattop guitars. All are used in popular music genres, including rock, blues and folk. Other styles of guitar which enjoy moderate popularity in more specific genres, include: The archtop, which incorporates an arched, violin-like top either carved out of solid wood or heat-pressed using laminations, it has violin style f-holes rather than a single round sound hole. It is most used by swing and jazz players and incorporates an electric pickup; the Selmer-Maccaferri guitar is played by those who follow the style of Django Reinhardt. It is an unusual-looking instrument, distinguished by a large body with squarish bouts, either a D-shaped or longitudinal oval soundhole; the strings are gathered at the tail like an archtop guitar. It has a wide fingerboard and slotted head like a nylon-string guitar; the loud volume and penetrating tone make it suitable for single-note soloing, it is employed as a lead instrument in gypsy swing.

The resonator guitar or resophonic guitar called the Dobro after its most prominent manufacturer, amplifies its sound through one or more metal cone-shaped resonators. It was designed to overcome the problem of c

San Francisco Bay Area Renters' Federation

The San Francisco Bay Area Renters' Federation is a political advocacy group formed in response to the present-day San Francisco housing shortage. SFBARF advocates for more housing development, fewer zoning restrictions on the production of housing, it is one of several formed YIMBY groups in the San Francisco Bay Area. SFBARF is an unincorporated club; the organization's acronym barf, a slang term for vomiting, was deliberately chosen to improve the group's name recognition. SFBARF engages in anti-"NIMBY" political activity, such as rallying for housing projects, campaigning for legislation, organizing events; the press has referred to SFBARF as an "avidly pro-development grass-roots activist group" aiming to increase the height and density of buildings allowed under San Francisco Bay Area zoning regulations. The New York Times says of the group: "Its platform is simple: Members want San Francisco and its suburbs to build more of every kind of housing. More subsidized affordable housing, more market-rate rentals, more high-end condominiums."

The group was founded in early 2014 by a self-described anarchist. A prep school math teacher, Trauss now leads the group full-time; as of April 2016, the group had a mailing list of 500 people and a "a few dozen hard-core members — most of them young professionals who work in the technology industry — who speak out at government meetings and protest against the protesters who fight new development." Opponents have accused the organization of being funded by the real estate industry. SFBARF has denied this claim. Yelp CEO Jeremy Stoppelman has donated $10,000 to the group. In 2015, SFBARF campaigned to take over the leadership for the San Francisco chapter of the Sierra Club, claiming that the local chapter opposed high-density development, such as 2015's Proposition D in Mission Bay. According to the San Francisco Business Times, SFBARF "believes that blocking dense housing near transit encourages sprawl,", environmentally destructive; the national Sierra Club supports infill development. The campaign was criticized in an editorial in VICE, which said that one of the candidates SFBARF supported, Donald Dewsnup, had a history of using "shady" activism tactics.

(Dewsnup was convicted of voter fraud. The group has invoked California's Housing Accountability Act in order to sue cities when they attempt to block, restrict, or down-size housing development, their first suit was in 2015, when SFBARF sued the city of Lafayette, California for blocking a housing development. The group referred to this as part of their "Sue the Suburbs" campaign, creating a website under this name; the suit claimed that under California's Housing Accountability Act, the Lafayette city council could not force developers to reduce the density of a housing project, since the project complied with all zoning laws. In a televised debate with SFBARF, Lafayette mayor Brandt Andersson argued the suit was unwarranted, saying that Lafayette should "keep multi-unit housing downtown" near the BART station. In April 2015, a developer submitted an application to tear down a dilapidated building at 1310 Haskell Street in Berkeley, replace it with three two-story homes. In July 2016, the Berkeley City Council voted 5-0 to deny the proposal.

The city was sued by the SF Bay Area Renters Federation, who argued that denying the application violated California's Housing Accountability Act. In October 2016, the city settled the lawsuit by agreeing to reconsider the proposal. In July 2017, the judge ruled in favor of SFBARF. In September 2017, the Berkeley City Council voted to settle the lawsuit. San Francisco housing shortage California housing shortage Sue the Suburbs website

HMS Dalriada

HMS Dalriada is Glasgow's Royal Naval Reserve unit. It is based in one of the city's south-western suburbs. HMS Dalriada was established as a Royal Naval Reserve Headquarters Unit for Greenock and the Firth of Clyde, Scotland in 1965 and occupied former air defence buildings on the outskirts of Inverkip. Dalriada remained in Inverkip until 1982, when the unit moved to the Navy Buildings in Greenock, on the site of the former gun battery at Fort Matilda. Dalriada was named after the 6-7th Century Gaelic over-kingdom Dál Riata in which modern Greenock is located; the Ship's Badge of Dalriada has the boar's head of Clan Campbell with a Celtic torc and surmounted with a coronet. The letters R N R surround the device and all is enclosed within a diamond surmounted in turn by a plaque with the ship's name and above that the Naval Crown; the principal RNR unit in Glasgow and the West of Scotland had been, since 1903, HMS Graham, based at Whitefield Rd in Govan. At that time RNR Divisional HQs such as HMS Graham were considered senior to HQ Units such as HMS Dalriada in having greater numbers of Reservists and RN Staff attached and in operating active Ton Class Minesweepers as part of the Tenth Mine Counter Measure Squadron.

Dalriada had been set up as a tender unit to HMS Graham on which it relied for administrative and other functions. The 1990 Options for Change changes in RNR Force sizes saw the closure of HMS Graham and the refocusing of the RNR in the West of Scotland on HMS Dalriada; this left Glasgow City without an RNR presence, the Govan site was handed over to the Army for use by the Territorial Army's 205 Field Hospital of the 2nd Medical Brigade. After some years the RNR presence in the City of Glasgow was restored through the creation of a satellite unit to HMS Dalriada - Govan Division. In April 2013, Dalriada moved to Govan, subsuming its satellite unit and co-locating with the Royal Marines Reserve Glasgow Detachment. Members of HMS Dalriada take part in ceremonial events hosted by the city of Glasgow alongside their regular counterparts from HMS Neptune, HMNB Clyde. During the Glasgow 2014 Commonwealth Games, Dalriada provided personnel to supplement Police Scotland's security operation. Many of the unit's members took part in flag raising and medal presentation ceremonies as part of the event.
