London Assembly
The London Assembly is an elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds majority, to amend the Mayor's annual budget. The Assembly was established in 2000 and is headquartered at City Hall on the south side of the River Thames close to Tower Bridge.
The Assembly is also able to investigate other issues of importance to Londoners, publish its findings and recommendations, and make proposals to the Mayor.
Although the Assembly's powers are fairly limited, the body is increasingly seen as a stepping stone to Parliament. In the time since its creation in 2000, six Assembly members have been elected to the House of Commons: David Lammy, Meg Hillier and Diana Johnson for Labour; Andrew Pelling and Bob Neill for the Conservatives; and Lynne Featherstone for the Liberal Democrats. In addition, Angie Bray and Bob Blackman have been selected as the Conservative parliamentary candidates for the marginal seats of Ealing Acton and Harrow East at the next general election.

Diocese of Argyll and the Isles (Episcopalian)
This article is on the diocese of the Scottish Episcopal Church; for the Catholic diocese, see Diocese of Argyll and the Isles (Catholic).
The Diocese of Argyll and the Isles is in the west of Scotland, and is one of the seven dioceses of the Scottish Episcopal Church. It is perhaps the largest of the dioceses, but has the smallest number of church members. It covers Argyll and Bute, the Isle of Arran, Lochaber, the Isle of Skye and the rest of the Hebrides. As a united diocese, Argyll and the Isles has two cathedrals: St John's in Oban and the Cathedral of the Isles in Millport, Isle of Cumbrae.
The Diocese of the Isles, by itself, was founded by Patrick in 900, and the Diocese of Argyll was founded by Bishop Harald in 1193. During the Scottish Reformation, most of the heritage and jurisdiction of the church was given to the Church of Scotland. However, the small Scottish Episcopal Church has maintained the line of bishops of both dioceses through to the present day. In the seventeenth century, the Diocese of the Isles was united with the dioceses of Caithness and Orkney, and, in 1819, was separated from them to unite with the Diocese of Argyll. In 1878, the Roman Catholic Church created a Diocese of Argyll and the Isles. The current Bishop of Argyll and the Isles is the Right Reverend Martin Shaw.
The Diocese of Argyll and the Isles is twinned with the Anglican Diocese of Zanzibar (Anglican Church of Tanzania) and the Episcopal Diocese of Delaware (Episcopal Church of the United States of America).

Downtown Halifax Link
The Downtown Halifax Link system is similar to Toronto's PATH or Montreal's RÉSO system, but on a much smaller scale. It consists of a network of climate-controlled pedways (pedestrian tunnels and skywalks) connecting various office buildings, hotels, parkades, and entertainment venues around downtown Halifax, Nova Scotia, Canada. These walkways are all open to the public, and are convenient during inclement weather and the winter months.

Limnology
Limnology (from Greek: Λίμνη limne, "lake"; and λόγος, logos, "knowledge") is the study of inland waters (both fresh and saline), including their biological, physical, chemical, geological and hydrological aspects. This includes the study of (natural and man-made) lakes and ponds, rivers and streams, wetlands and groundwaters.
François-Alphonse Forel (1841-1912) established the field with his studies of Lake Geneva. Limnology traditionally is closely related to hydrobiology, which is concerned with the application of the principles and methods of physics, chemistry, geology, and geography to ecological problems.

The London Oratory School is a Catholic voluntary aided comprehensive secondary school in Fulham, London educating boys in the age range of 7-16 and boys and girls in the age range 16-18 (the sixth form). There are 1338 pupils including 354 in the sixth form. The Headmaster is David McFadden BSc MA.

History
The school's most recent Ofsted report classed it as outstanding, the highest possible grade[1]. The school offers an unrivalled range of extra-curricular activities. On any single day there may be more than 20 activities on offer, before and after school and during lunch time. Many of these activities are musical where the school has a real strength. Other activities include the Combined Cadet Force, societies and modern languages enrichment. Such activities allow pupils to experience challenge and to work productively together. In addition there is a wide range of sports fixtures, school journeys, visits and cultural activities. Many sporting activities take place at the Barn Elms sport centre in South West London, however extra facilities have been recently added to the school site, including cricket nets and tennis facilities. The Arts Centre provides a venue for exhibitions and performances of a high quality. In the sixth form there is a popular debating society and there is good provision for girls to take part in activities including a successful girls' rugby team. Participation rates in extra-curricular activities are high. In keeping with the ethos of a Catholic school opportunities are provided for pupils to take part in retreats such as those to Aylesford Priory, Fawley Court and Lourdes.
The school uniform is a black blazer with an embroidered orange and red shield; sixth form boys wear a black jacket with the complete coat of arms while girls wear a striped blazer. The school admits pupils from a wide range of backgrounds and has an extensive catchment area, with pupils travelling from as far away as Uxbridge in the west, Tower Hamlets in the east, Muswell Hill in the north and Kingston upon Thames in the south.
A very high proportion of pupils go on to higher education, with many gaining places at the country's most prestigious universities. Recent years have seen impressive Oxbridge success. In keeping with the school's policy of catering for a broad range of academic ability, assistance is given in applications to all institutions of higher education. The objective throughout the school is to aim to fulfill each pupil's potential, which of course is different for every individual. The school makes strenuous efforts to ensure students with special educational needs have proper care and support, a fact recognised in the most recent Ofsted Inspection Report.
The senior school is divided into six houses, Campion, Fisher, Howard, More, Owen and Southwell, each with a housemaster, who, together with the form tutors, are responsible for the academic and social well-being of those in the house. Pupils in each house have lunch together in the Houseroom every day and all houses compete in the various sports challenges, such as the House Rugby Competition. Houses are thought to promote unity and friendly competition in the school, across all years.
The Modern Languages department at the London Oratory School is considered to be particularly strong. In 2005, the Department were given the award for best A-Level results in Modern Languages of all state schools in England. Advanced Extension Awards are offered to those pupils with a particular gift in their subject.
Since 11th November 2006, on Saturdays, Polish students attend the Henryk Sienkiewicz Polish School that takes place in the London Oratory School. Students of the school range from the age of 5 to 17, where students also study to take GCSE and A-Level examinations, usually a year earlier than students do for other subjects. The Headmaster of the Henryk Sienkiewicz Polish School is Wojciech Poza, a chemistry teacher at the school.

Student Life
The Music Department is highly renowned, and the Junior House, formed in 1996, gives a rigorous education to boys from the age of seven to eleven in all subjects in the context of a thorough musical education. The department has five full time music teachers, and a large number of visiting instrumental and singing teachers who give singing and instrumental lessons throughout the week. For pupils with an aptitude for music and a desire to study seriously, the school affords extensive opportunities for tuition, study and performing in public. There are five choirs: The Schola, the Junior House Choir, the School Choir, the Chamber Choir and the Girls' Choir. The director of music is Lee Ward, who is also director of music at Hampstead Parish Church. Ward is Director of The Schola, Chamber Choir and School Choir but as of September 18, 2007 he has stepped down and made his fellow colleagues David Terry and Clare Dawson in charge of the Chamber and School Choir. The School Choir and the Chamber Choir are open to all pupils with choral ability, the Chamber Choir specialising in the more demanding music, particularly the traditional liturgical music of the Catholic Church. The Girls' Choir is drawn from the girls in the sixth form. The Choral Society is open to parents, staff and friends and performs a concert each term in venues in London. Recently performed works include; Verdi's Requiem, Orff's Carmina Burana, Elgar's Dream of Gerontius, Mozart's Mass in C minor, Bach's Magnificat, Duke Ellington's Sacred Concert, Bach's Mass in B Minor, Pärt's Miserere, Monteverdi's 'Vespers' Allegri's Miserere and Lauridsen's Lux Aeterna.
In recent years pupils have taken part in the school's productions of Purcell's Dido and Aeneas and King Arthur, Britten's Golden Vanity, Noye's Fludde and The Children's Crusade, Menotti's Amahl and the Night Visitors, Richard Rodney Bennett's opera All the King's Men, The Ballad of Solomon Pavey, an Elizabethan ballad opera about the children of the Chapel Royal, Gilbert and Sullivan's Iolanthe, The Mikado, Patience, Trial by Jury and The Pirates of Penzance, The Beggars Opera by John Gay, Mozart's The Magic Flute, The Marriage of Figaro and Cosi Fan Tutte, Offenbach's Orpheus in the Underworld, Sondheim's A Funny Thing Happened on the Way to the Forum, Bizet's Carmen and Rodgers and Hammerstein's The Sound of Music.
The choirs regularly give concerts of sacred and secular music at the school and also out of school and have performed at Oxford and Cambridge colleges, the Royal Albert Hall, the Royal National Theatre and the Purcell Room on the South Bank and in addition, some pupils sing at the English National Opera and the Royal Opera House. The choirs have also toured extensively abroad and many pupils have in the past visited; Paris, Germany, America, Rome, Krakov, Berlin, Bareclona, New York and Lisbon. The school has provided choirs for film scores such as The Lord of the Rings. The chamber choir, schola and girls' choir from the school sang with professional soloists and the Colla Voce singers (an ensemble largely composed of former pupils who have gone on to music scholarships) at a concert in the London Oratory Church, for the retirement as headmaster of John McIntosh OBE, on Saturday 9th December 2006. This was attended by HRH The Princess Michael of Kent and the Prime Minister, Rt Hon. Tony Blair MP.
Over 500 pupils attend more than 700 weekly individual music lessons given by some of London's leading professional musicians in a wide variety of instruments. Where possible instruments are loaned to pupils in the initial stages. Pupils are entered for the Associated Board of the Royal Schools of Music examinations. The school's Symphony Orchestra and various ensembles provide pupils with an excellent introduction to group music making. All orchestral instrumentalists are encouraged to join one or more of the groups such as the Symphony Orchestra, Chamber Orchestra, Junior Strings, Concert Band and several chamber groups and a jazz group: The Seagrave Stompers. Choral and orchestral concerts are held each term in the theatre and pupils and teachers give lunch time recitals in the foyer of The John McIntosh Arts Centre and Junior House choir room. The school possesses two types of electronic organ: a three manual Allen organ in the Chapel and a two manual organ in The John McIntosh Arts Centre. There is also a fine two manual Goble harpsichord for pupils learning keyboard instruments and for use in school concerts. The school has recently acquired a concert harp and now has eight pupils learning this instrument.

Music at the School
The London Oratory School Schola was established in 1996 as a means of providing Catholic boys from the age of seven with a rigorous choral education within the maintained system, something hitherto only available in the independent system. The school's close association with the London Oratory places it in a strong, if not unique, position to provide this form of specialist education and to contribute to the development of traditional liturgical music.
The partnership between the London Oratory and the school provides ideal opportunities for the school to train boys within the context of a living tradition of catholic liturgy.
The Oratory is part of a dynamic liturgical and musical tradition which goes back to the sixteenth century when the first Oratory was established in Rome at the time of the Counter-Reformation. Both Giovanni Pierluigi da Palestrina and Tomás Luis de Victoria were closely associated with the Oratory and Philip Neri, its founder, and Victoria became an Oratorian.
In particular, the houses of the Oratory in Europe have been closely associated with the development of sacred polyphony and Gregorian Chant. The Oratory in London has a reputation for maintaining this tradition and for providing some of the finest liturgy and liturgical music in Europe today. The school has a strong musical tradition and for many years has been closely associated with liturgy and music of the Oratory.
The Schola sings at the Saturday evening Mass at the Oratory every week in term time and at other Masses and services during and outside term, and in the School Chapel during the week. In addition to the liturgical commitment, concert work and touring are a regular feature of the choristers' lives. The choir also features on film soundtracks, including the whole of The Lord of the Rings film trilogy and Harry Potter and the Prisoner of Azkaban (film).
Choristers normally join the school at the age of seven and are selected by audition, examination and an exhaustive interview, although places may sometimes be available to boys who join the school later, including during the sixth form. Choristers rehearse at 8 o'clock every morning, for an hour immediately before services, and frequently during the lunch break and after school. Boys are given individual voice training. When their voices change, and the time comes for choristers to step down as trebles and altos, they devote more time to their instrumental music; their interest in singing is kept alive until their voices have developed sufficiently to enable them, where appropriate, to return to The Schola. The Schola is supported by lay clerks, some of whom are members of the Oratory Choir. Choristers are fully involved in other aspects of the musical life of the school.
The Oratory School Schola Foundation has been set up to raise funds to supprt the development of the Schola and its overseas tours, as unlike Cathedral choirs it has no endowments or external source of income.

The Schola
Drama plays an important part in the life of the school. There are several productions each year: a major drama and opera production in conjunction with the Music Department, smaller scale productions by the Drama Club and other groups of pupils and periodic performances by visiting companies. In recent years the school has presented Macbeth, Twelfth Night, A Midsummer Night's Dream, The Taming of the Shrew, The Comedy of Errors and Much Ado about Nothing (all by Shakespeare). Other productions have been Molière's Le Bourgeois Gentilhomme and The Hypochondriac, Gogol's The Government Inspector, Shaw's The Devil's Disciple and Pygmalion, Beckett's Endgame, Edward Bond's The Sea and Stone as well as Toad of Toad Hall, The Elephant Man, numerous one-act plays including four by Chekhov, Arthur Miller's The Crucible and A View from the Bridge, Oscar Wilde's The Importance of Being Earnest, Peter Shaffer's Black Comedy, Noel Coward's Blithe Spirit, Alan Bennett's Habeas Corpus, Keith Dewhurst's Don Quixote and Rostand's Cyrano de Bergerac, Sheridan's School for Scandal, Webster's The Duchess of Malfi, Brian Friel's Translations, Ben Jonson's Volpone, Timberlake Wertenbaker's Our Country's Good, Alice in Wonderland, Shakespeare's The Tempest, South Pacific and most recently Gargling with Jelly"
Great importance is attached to all theatrical skills so that pupils become closely involved in the design and construction of scenery, the making of costumes, the use of the school's extensive and up-to-date lighting system, in stage management and the techniques of make-up. Several members of staff direct, often assisted by pupils from the sixth form.

Drama
The School's CCF is sponsored by The Rifles and The Royal Air Force. Membership is voluntary and open to pupils aged thirteen and over. Meetings are held every week on a Friday after school, this includes a parade, lessons and a final parade. Activities normally held on weekend camps include abseiling, canoing, shooting, climbing, lightweight camping, flying, gliding, swimming and sport, in addition to subjects taught in the Combined Cadet Force training syllabus. Royal Air Force cadets attend voluntary flying lessons at least twice a month. The two sections of the school's CCF regularly achieve great success in the national competitions, and in 2007 the RAF section achieved 5th place in the national finals of the Ground Training Competition held at RAF Uxbridge, while the Rifles section finished 4th in the Swift and Bold competition at Stowe School. The Rifles section have won that competition in the two previous years (2006 and 2005) while the RAF section collected 2nd place in the Ground Training Competition in 2005 and 3rd in 2004.

The Trecento was a period of vigorous activity in Italy in the arts, including painting, architecture, literature, and music. The music of the Trecento paralleled the achievements in the other arts in many ways, for example in pioneering new forms and new forms of expression, especially in secular song in the vernacular language, Italian. In these regards the music of the Trecento may seem more to be a Renaissance phenomenon; however, the predominant musical language was more closely related to that of the late Middle Ages, and musicologists generally classify the Trecento as the end of the medieval era.

Background
Some of the poetry of Dante Alighieri (1265–1320) was set to music at the time it was written, but none of the music has survived. One of the musicians to set Dante's poetry was his friend Casella (died 1299 or 1300), memorialized in Canto II of Purgatorio. Poems of Dante set by others included canzoni and ballatas; if they were similar to the other earliest ballatas, they would have been monophonic.
The earliest polyphonic secular vocal music of the Trecento to survive is found in the Rossi Codex, and includes music by the first generation of Trecento composers: Maestro Piero, Giovanni da Cascia, as well as numerous composers who are anonymous. Other composers of the first generation include Vincenzo da Rimini and Jacopo da Bologna, who was probably the teacher of Francesco Landini. All of these composers were associated with aristocratic courts in the north of Italy, specifically Milan, Padua, and Verona. Some extremely obscure names survive in later sources, such as Bartolo da Firenze (fl. 1330–1360), who may have been the first Italian composer to write a polyphonic mass movement: a setting of the Credo.
This generation of composers usually wrote music with both voices singing the same text, in the manner of the conductus, and they preferred the form of the madrigal. While some of their music was still monophonic in the manner of the preceding century, much was for two voices, and Jacopo da Bologna wrote a few madrigals for three voices. Jacopo wrote one motet which has survived; motets from 14th century Italy are extremely rare. Indeed relatively little sacred music was produced by any composers in 14th century Italy: the almost complete focus on secular music by these composers, many of whom had musical careers in churches and could have been expected to write large quantities of sacred music, as did their descendants, is unique in medieval and early Renaissance history.

Early Trecento
The center of musical activity moved south in mid-century, to Florence, which was the cultural center of the early Renaissance. Characteristic of the next generation of composers, most of them Florentine, was a preference for the ballata, a form which seems to have exploded into popularity around mid-century. By far the most famous composer of the entire Trecento, Francesco Landini (c.1325–1397), was a member of this generation. Other composers of this group besides Landini included Gherardello da Firenze, Lorenzo da Firenze, and Donato da Cascia. Also by this generation of composers, the influence of French music was becoming apparent in the secular work of the native Italians.
Greater independence of voices was characteristic of the music of this generation, and points of imitation are common; in addition, the uppermost voice is often highly ornamented. Landini's music was particularly admired for its lyricism and expressive intensity: his fame has endured for six hundred years, and numerous contemporary recordings exist of his work.
The preferred form at this time was the ballata, which is closely related to the French virelai. Landini wrote 141 which have survived, but only 12 madrigals. Another form which became popular after the middle of the century was the caccia, most likely derived from the French chace, which was a two-voice canon.
Giovanni Boccaccio mentions Florentine music in the Decameron. He tells how in 1348, the year the Black Death ravaged Florence, members of a group of friends gathered to tell stories and sing songs, to instrumental accompaniment. While Boccaccio mentioned no composers by name, many of the Florentine musicians whose names have come down to us were in their early careers at this time.

Peak of the Trecento
The last generation of composers of the era included Niccolò da Perugia, Bartolino da Padova, Andrea da Firenze, Paolo da Firenze, Matteo da Perugia, and Johannes Ciconia, the first member of the group who was not a native Italian. Their principal form was the ballata, and the ornamentation of the parts is considerably less than in the music of the preceding group of composers. Text-painting is evident in some of their music: for example, some of their programmatic compositions include frank imitations of bird-calls or various dramatic effects. Ballate continued to be composed into the 15th century, and the form is closely related to the later frottola.
Ciconia, as a Netherlander, was one of the first of the group which was to dominate European music for the next two hundred years; early in his life he spent time in Italy learning the lyrical secular styles. Ciconia was also a composer of sacred music, and represents a link with the Burgundian school, the first generation of Netherlanders, which dominated the early and middle 15th century. Ciconia spent most of his Italian years in cities of northern Italy, including Venice and Padua; he died in Padua in 1412.
Another late 14th century composer, probably active in Rome, Abruzzo, and Teramo, was Antonio Zacara da Teramo. While a chronology of his music is yet to be established, it seems that his earlier music, surviving in the Squarcialupi Codex, is related to the style of Landini and Jacopo da Bologna; his later music borrows from the style of the Avignon-centered Ars subtilior, and indeed he seems to have supported the antipopes during the split of the papacy after the end of the century, going to Bologna around 1408.
The end of the Trecento marked the end of the dominance of Florence over Italian music; while it always maintained an active musical life, it would be replaced by Venice, Rome, Ferrara and other cities in the coming centuries, and never again regained the pre-eminent position it attained in the 14th century. By the first decade of the 15th century, the quattrocento, Venice had emerged as the leading power in Northern Italy; the foundation of a singing school there in 1403 was one step towards their equivalent emergence as a musical power.

Late Trecento and transitional era
Instrumental music was widespread, but relatively few notated examples have survived. Indeed while contemporary depictions of singers often show them performing from books or scrolls, paintings and miniatures of instrumentalists never show written music. The main keyboard collection is the Faenza Codex (Faenza, Biblioteca Comunale, ms. 117). Other small sources of keyboard music appear in codices in Padua (Archivio di Stato 553), Assisi (Biblioteca Comunale 187), and in one section of the Reina Codex (Paris, Bibliothèque Nationale de France, n. a. fr. 6771). The typical keyboard style of the time seems to have placed the tenor of a secular song or a melody from plainchant in equal tones in the bass while a fast-moving line was written above it for the right hand. The surviving sources are likely among the few witnesses of a largely improvised tradition.
Other instrumental traditions are hinted at by the monophonic, untexted dances in a manuscript now in London (British Library, add. 29987) and in imitations of instrumental style in sung madrigals and cacce such as Dappoi che'l sole.
Instruments used during the Trecento included the vielle, lute, psaltery, flute, and organetto (portative organ: Landini is holding one in the illustration). Trumpets, drums (especially paired drums called nakers), and shawms were important military instruments.

Music of the Trecento Instrumental music
Music of the Trecento retained some characteristics of the preceding age, and began to foreshadow the Renaissance in others.
Consonances were unison, fifth and octave, just as in the ars antiqua, and the interval of a third was usually treated as a dissonance, especially earlier in the period. Parallel motion in unison, fifths, octaves, thirds, and occasionally fourths was used in moderation. Composers used passing tones to avoid parallel intervals, creating brief harsher dissonances, foreshadowing the style of counterpoint developed in the Renaissance. After 1350, there was increased use of triads in three-part writing, giving the music, to a modern ear, a tonal feeling. Accidentals occurred more frequently in music of the Trecento than in music of earlier eras; in particular, there was use of F, C, G, B, and E. One A occurs in the works of Landini.
The Landini sixth, also known as the Landini cadence or under-third cadence, is a cadence involving the melodic drop from the seventh to the sixth before going up again to the octave. It was named after Landini because of its frequent use in his music. It was, however, not invented by him, and can be found in most of the music of the period.

Overall musical characteristics of the era
Most of the manuscript sources of trecento music are from late in the fourteenth or early in the fifteenth century: some time removed from the composition of the works themselves. The earliest substantial manuscript source of trecento music is the Rossi Codex, which was compiled sometime between 1350 and 1370, and contains music from the earlier portion of the era. However, other small manuscript sources have been found that expand our knowledge of earlier trecento repertories. These include the Mischiati fragments of Reggio Emilia, which contain several unique cacce. and scholarly consensus is building that the manuscript is no earlier than other sources commonly dated to the 1390s. Still, this episode reflects the difficulties and uncertainties of dating all trecento sources.
Most of the later large sources stem from the area around Florence. Probably the oldest of the larger sources is the Panciatichi Codex, no. 26. The largest and most beautiful trecento source is undoubtedly the brilliantly illuminated Squarcialupi Codex, compiled in the early 15th century, which, with 352 compositions (including 145 by Landini) is one of the largest music sources of the time from any region.
Substantial fragmentary manuscript sources from Padua, Cividale del Friuli, and from the area around Milan point to these areas as substantial areas of manuscript production as well. Few Italian compositions were copied outside of Italy, though the sacred music of Ciconia and Zacara appear in some Polish manuscripts of the fifteenth century.
