Eurasian Collared Dove

Saturday, May 30th, 2009

Eurasian Collared Dove

Conservation status

Least Concern (IUCN 3.1)
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Columbiformes
Family: Columbidae
Genus: Streptopelia
Species: S. decaocto
Binomial name
Streptopelia decaocto
Frivaldszky, 1838


A young collared dove.

The Eurasian Collared Dove, Streptopelia decaocto, also spelled Eurasian Collared-Dove or called simply the Collared Dove, is one of the great colonisers of the avian world. Its original range was warmer temperate regions from southeastern Europe to Japan. However, in the twentieth century it expanded across the rest of Europe, reaching as far west as Great Britain by 1953; breeding in Britain for the first time in 1956, and Ireland soon after. It also now breeds north of the Arctic Circle in Scandinavia. It is not migratory.

It was introduced into the Bahamas in the 1970s and spread to Florida by 1982. Its stronghold in North America is still the Gulf Coast, but it is now found as far south as Veracruz, as far west as California, and as far north as British Columbia and the Great Lakes. Its impact on native species is as yet unknown; it appears to occupy an ecological niche between that of the Mourning Dove and Rock Pigeon; some have suggested that its spread represents exploitation of a niche made available by the extinction of the Passenger Pigeon.


A profile of a collared dove.

It breeds wherever there are trees for nesting, laying two white eggs in a stick nest. The eggs are incubated by the female during the night and by the male during the day. Incubation lasts 14-18 days, and young fledge after 15-19 days. It is not wary and is often found around human habitation.

This is a small dove, buff grey with a darker back and a blue-grey wing patch. The tail feathers are tipped white. It has a black half-collar on its nape from which it gets its name. The short legs are red and the bill is black. The iris is reddish brown, but from a distance the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown eye colour can be seen around the black pupil.

This is a gregarious species, and sizable winter flocks will form where there are food supplies such as grain. The song is a coocoo, coo repeated many times. It is phonetically similar to the Greek, decaocto (’eighteen’), to which the bird owes its name. Occasionally it also makes a harsh loud mechanical-sounding call lasting about 2 seconds, particularly when landing in the summer.

The Eurasian Collared Dove is one of two species (the other, and the more likely, being the African Collared Dove, Streptopelia roseogrisea) that have been argued to be the wild ancestor of the domestic Barbary Dove, S. risoria. It is able to interbreed with the Barbary Dove.

History

The original story begins by introducing a handsome 22 year old Danijel Loncar (Zoran Pribicevic) coming home to Zagreb, on his 22nd birthday, after losing his job in Italy. At the railway station, he bumps into a beautiful girl. They both feel immediate attraction. Danijel doesn’t even get the chance to ask for her name as they are greeted by their friends and family.

The girl is Petra Novak (Anita Berisha) who also returned home, after studying photography in London, funny enough, on a present day she also celebrates her 22nd birthday.

It soon transpires that Danijel and Petra were twins separated at birth. Danijel had initially been raised by the wise Nada Horvat (Nada Rocco) before returning to his father Josip Loncar (Drazen Mikulic), and Petra raised by her mother Viktorija Novak (Sanja Vejnovic) who had married into money to a rich aristocrate widower Stjepan Novak (Velimir Cokljat).

The parents of the twins had each married other people and raised families which had other adult children. The Loncar family comprised Danijel’s father Josip Loncar, a construction worker; and Josip’s wife Biserka Loncar (Vanja Matujec), a warm-hearted, down-to-earth housewife. Their children were Iva Loncar (Marija Kobic) and Matija (Filip Ri?icki), Iva had just started a romantic involvement with Igor Carevic (Dejan Marcikic) and Matija started seeing his class member Lana Kos (Petra Kurtela). Petra had grown up with her mother Viktorija (Sanja Vejnovic), Viktorija’s husband Stjepan who was a successful wineyard owner and businessman, and Stjepan’s son from an earlier marriage, the spiteful Borna Novak (Mario Valentic).

After Danijel’s investigation into Petra’s whereabouts, he slowly enters the world of the powerful Novak family by landing a job as a gardner, not knowing he is working for his biological mother, nor that he has fallen in love with his own sister.

Other major characters include Lidija Bauer (Katja Zupcic) who has always had strong feelings for Stjepan, but who stepped away out of respect towards the family and her children. Lidija has two children of her own: the spoiled and stubborn teenager Tina Bauer (Antonija Sola)and the good-natured medical student Leon Bauer (Mario Mohenski) later (Marin Knezevic), who was betrothed to Petra at Viktorija’s instigation only for the wedding to be cancelled after a revelation about his homosexuality. Viktorija’s best friend, the dizzy socialite Stela Vidak (Matija Prskalo), was introduced as a minor figure during the show’s early days as someone to whom Viktorija could recite expository dialogue about her latest scheme to, but soon emerged as a key character.

Biography

Early years

Born to a Jewish family in Pittsburgh, Pennsylvania he graduated from high school in 1907 and pursued legal studies, but grew disenchanted and took on a series of odd jobs. Kaufman then began his career as a journalist and drama critic. He was the drama editor for The New York Times.

Career

Theatre

His Broadway debut was in 1918 with Someone in the House, written with Larry Evans and W.C. Percival. This play was panned, and it had the further handicap of opening on Broadway during a flu epidemic, when theatre attendance in New York City diminished drastically because the public were warned to avoid crowds. Kaufman sardonically advised his play’s producers to print advertisements with this message: “Avoid crowds: see Someone in the House.”

It would be quite a long time before Kaufman had another flop. In every Broadway season from 1921 through 1958, there was a play written or directed by Kaufman. Since Kaufman’s death in 1961, every decade has featured at least a couple of revivals of his work. There have also been productions based on Kaufman properties, such as the 1981 musical version of Merrily We Roll Along, adapted by George Furth and Stephen Sondheim.

Kaufman was known as “The Great Collaborator” because he wrote very few plays alone. His most successful solo script was The Butter and Egg Man in 1925. With others, Kaufman was prolific: with Marc Connelly he wrote Merton of the Movies, Dulcy, and Beggar on Horseback; with Ring Lardner he wrote June Moon; with Edna Ferber he wrote The Royal Family, Dinner at Eight, and Stage Door; with John P. Marquand he wrote a stage adaptation of Marquand’s novel The Late George Apley; and with Howard Teichmann he wrote The Solid Gold Cadillac.

For a period Kaufman lived at 158 West 58th in New York City. The building would be the setting for Stage Door. It is less than two blocks from Broadway. It is now the Park Savoy Hotel and for many years was considered a single room occupancy hotel.

His most successful collaborations were with Moss Hart, with whom he wrote many plays, including Once in a Lifetime, Merrily We Roll Along, You Can’t Take It With You, his most-revived play, which won the Pulitzer Prize in 1937, and The Man Who Came to Dinner.

Despite his claim that he knew nothing about music and hated it in the theatre, Kaufman collaborated on many musical theatre projects. His most successful such efforts include two Broadway shows crafted for the Marx Brothers, The Cocoanuts, written with Irving Berlin, and Animal Crackers, written with Morrie Ryskind, Bert Kalmar, and Harry Ruby. These two productions allowed the Marx Brothers to make the transition from their vaudeville roots into the more prominent worlds of “legitimate” musical comedy and film. Kaufman was one of the writers who excelled in writing intelligent nonsense for Groucho Marx, a process that was inevitably collaborative, given Groucho’s skills at expanding upon the scripted material. Though the Marx Brothers were notoriously critical of their writers, Groucho and Harpo Marx expressed admiration and gratitude towards Kaufman. (Dick Cavett, introducing Groucho onstage at Carnegie Hall in 1972, told the audience that Groucho considered Kaufman to be “his god”.)

In spite of Kaufman’s success as a co-writer and director of stage musicals (one of his biggest musical hits was Guys and Dolls, which he directed on Broadway but did not write), there is some truth to the legend about his lack of musical instincts. While The Cocoanuts was being developed in Atlantic City, Irving Berlin was hugely enthusiastic about a song he had written for the show. Kaufman was less enthusiastic, and refused to rework the libretto to include this number. The discarded song was Always, ultimately a huge hit for Berlin (in another show). The Cocoanuts would remain Irving Berlin’s only Broadway musical — until his very last one, Mister President — which did not include at least one eventual hit song.

Humor derived from political situations was of particular interest to Kaufman. He collaborated on the hit musical Of Thee I Sing (1931 Pulitzer Prize, the first musical so honored), and its sequel Let ‘Em Eat Cake, as well as one troubled but eventually successful satire that had several incarnations, Strike Up the Band. Working with Kaufman on these ventures were Ryskind, George Gershwin, and Ira Gershwin. Also, Kaufman, with Moss Hart, wrote the book to I’d Rather Be Right, a musical starring George M. Cohan as Franklin Delano Roosevelt (the U.S. President at the time), with songs by Richard Rodgers and Lorenz Hart. He also co-wrote the 1935 comedy-drama First Lady.

This inveterate collaborator also contributed to historically important New York revues, including The Band Wagon (not to be confused with the Astaire/Minnelli 1953 film) with Arthur Schwartz and Howard Dietz. His often anthologized sketch “The Still Alarm” from the revue The Little Show lasted long after this influential show closed. Another well-known sketch of his is “If Men Played Cards As Women Do.”

Hollywood

Many of Kaufman’s plays were adapted into Hollywood films. Among the more well-received were Dinner At Eight, Stage Door (almost completely rewritten for the film version) and You Can’t Take It With You, which won the Best Picture Oscar in 1938. He also occasionally wrote directly for the movies, most significantly the screenplay for A Night at the Opera for the Marx Brothers. His only credit as a film director was The Senator Was Indiscreet (1947) starring William Powell.

On the boards, Kaufman directed the original productions of The Front Page by Charles MacArthur and Ben Hecht, Of Mice and Men by John Steinbeck, My Sister Eileen by Joseph Fields and Jerome Chodorov, Romanoff and Juliet by Peter Ustinov, and the Frank Loesser musical Guys and Dolls, for which he won the 1951 Best Director Tony Award. Kaufman produced many of his own plays as well as those of other writers. He also acted in the original production of his own Once In A Lifetime.

After World War II, perhaps because his output and commercial success as a writer was declining, Kaufman devoted more energy to directing, producing, writing prose, and appearing on television.

Kaufman was also a prominent rubber bridge player. Many of his humorous writings about bridge appeared in The New Yorker and have often been reprinted. They include Kibitzers’ Revolt and the ingenious suggestion that bridge clubs should post information that North-South or East-West are holding good cards.

Personal life

Kaufman was a key member of the celebrated Algonquin Round Table, a circle of witty writers and show business people. From the 1920s through the 1950s, Kaufman was as well known for his personality as he was for his writing. The Moss Hart autobiography Act One certainly popularized Kaufman as a character. Hart portrayed Kaufman as a morose and intimidating figure, uncomfortable with any expressions of affection between human beings — in life or on the page. This perspective, along with a number of taciturn observations made by Kaufman himself, led to a simplistic but commonly held belief that Hart was the emotional soul of the creative team while Kaufman was a misanthropic writer of punchlines.

Despite the fact that Kaufman lived in the public eye alongside celebrities and journalists, he was a tireless worker, dedicated to the writing and rehearsal processes. He was particularly revered within the business as a “play doctor.” Late in his life he managed to trade upon his long-developed persona by appearing as a television wag.

Of one unsuccessful comedy he wrote, “There was laughter at the back of the theatre, leading to the belief that someone was telling jokes back there.” Even though he was a sometime satirist, he remarked that “Satire is what closes on Saturday night.” Much of Kaufman’s fame occurred due to his mastery of sharp lines such as these, generally referred to in the press as “wise cracks.” However, Kaufman was more than a writer of gags. He created scripts that revealed a mastery of dramatic structure; his characters were likable and theatrically credible.

A noted philandering ladies’ man, Kaufman found himself in the center of a scandal in 1936 when, in the midst of a child custody suit, the former husband of actress Mary Astor threatened to publish one of Astor’s diaries purportedly containing extremely explicit details of an affair between Kaufman and the actress. The diary was eventually destroyed unread by the courts, but details of the supposed contents were published in Confidential magazine and various other scandal sheets. Kaufman later had a long affair with actress Natalie Schafer.

Kaufman was married in 1917 to Beatrice Bakrow until her death in 1945. Four years later, he married actress Leueen MacGrath on 26 May 1949 with whom he collaborated on a number of plays before their divorce in 1957. Kaufman died in New York City at the age of seventy-one.

Lorentz-Heaviside units

Friday, May 29th, 2009

Lorentz–Heaviside units (or Heaviside–Lorentz units) for Maxwell’s equations are often used in relativistic calculations. They differ from the equations in CGS-Gaussian units by a factor of  \sqrt {4 \pi} in the definitions of the fields and electric charge. The units are particularly convenient when performing calculations in spatial dimensions greater than three such as is done in string theory. Lorentz-Heaviside units are natural units in which \hbar={c}={\varepsilon_0}={\mu_{0}}={1}.

Maxwell’s equations with sources

The equations with sources take the following form:

where c is the speed of light in a vacuum. Here E is the electric field, B is the magnetic field, ? is the charge density, and J is the current density.

The charge and fields in Lorentz–Heaviside units are related to the quantities in cgs units by

Lorentz force

The force exerted upon a charged particle by the electric field and magnetic field is given in both cgs and Lorentz–Heaviside units by the Lorentz force equation:

where q is the charge on the particle and v is the particle velocity. The magnetic field B has the same units as the electric field E.
