John Augustus Roebling, Builder of the Brooklyn Bridge John Roebling (born June 12, 1806, Mà ¼hlhausen, Saxony, Germany) didnt invent the suspension bridge, yet he is well-known for building the Brooklyn Bridge. Roebling didnt invent spun wire roping, either, yet he became wealthy by patenting processes and manufacturing cables for bridges and aqueducts. He was called a man of iron, says historian David McCullough. Roebling died July 22, 1869, at age 63, from a tetanus infection after crushing his foot on the construction site of the Brooklyn Bridge.

After his brother died of heatstroke while farming, Roebling began working for the State of Pennsylvania as a surveyor and engineer, where he built dams, locks, and surveyed railroad routes. Building Projects 1842, Roebling proposed that the Allegheny Portage Railroad replace their continually breaking hemp coil ropes with steel coil ropes, a method he had read about in a German magazine. Wilhelm Albert had been using wire rope for German mining companies since 1834. Roebling modified the process and received a patent.1844, Roebling won a commission to engineer a suspension aqueduct to carry canal water over the Allegheny River near Pittsburgh. The aqueduct bridge was successful from its opening in 1845 until 1861 when replaced by the railroad.1846, Smithfield Street Bridge, Pittsburgh (replaced in 1883)1847 - 1848, the Delaware Aqueduct, the oldest surviving suspension bridge in the U.S. Between 1847 and 1851 Roebling built four DH Canal aqueducts.1855, Bridge at Niagara Falls (removed 1897)1860, Sixth Street Bridge, Pittsburgh (removed 1893)1867, Cincinnati Bridge1867, Plans the Brooklyn Bridge (Roebling died during its construction)1883, Brooklyn Bridge completed under the direction of his oldest son, Washington Roebling, and his sons wife, Emily Elements of a Suspension Bridge (e.g., Delaware Aqueduct) Cables are attached to stone piersCast iron saddles sit on the cablesWrought-iron suspender rods sit on the saddles, with both ends hanging vertically from the saddleSuspenders attach to hanger plates to support part of the aqueduct or bridge deck flooring Cast iron and wrought iron were new, popular materials in the 1800s. Restoration of the Delaware Aqueduct 1980, bought by the National Park Service to be preserved as part of Upper Delaware Scenic Recreational RiverAlmost all of the existing ironwork (cables, saddles, and suspenders) are the same materials installed when the structure was built.The two suspension cables encased in red piping are made of wrought iron strands, spun on site under the direction of John Roebling in 1847.Each 8 1/2-inch diameter suspension cable carries 2,150 wires bunched into seven strands. Laboratory tests in 1983 concluded that the cable was still functional.Wrapping wires holding the cable strands in place were replaced in 1985.In 1986, the white pine wooden superstructure was reconstructed using Roeblings original plans, drawings, notes, and specifications Roeblings Wire Company In 1848, Roebling moved his family to Trenton, New Jersey to start his own business and take advantage of his patents. 1850, established John A. Roeblings Sons Company to manufacture wire rope.

The Anonymous Author

The Anonymous Author I read an interesting essay recently, fully expecting to gloss it over and move on to my next email. But the theme grabbed my mind and wouldnt let go, and when that happens, when I see it matters to the writers I love, I usually convert the message into a FundsforWriters post. While fame impedes and constricts, obscurity wraps about a man like a mist; obscurity is dark, ample, and free; obscurity lets the mind take its way unimpeded. Over the obscure man is poured the merciful suffusion of darkness. None knows where he goes or comes. He may seek the truth and speak it; he alone is free; he alone is truthful; he alone is at peace. ~Virginia Woolfe Imagine being able to write without worry as to what the world thought of you? Imagine writing not caring how many books sold? Imagine just focusing on leaving your deepest thoughts on paper with no ramifications or backlash from family and friends? Virginia Woolfe said it best when she stated, the delight of having no name, but being like a wave which returns to the deep body of the sea. Oh my goodness, I could envision and embrace that feeling. Isnt that what we crave as writers? To write without repercussions? To write from our most inside place and let it loose into the world then retreat back to our inner self and write again? When we write solely for profit, our writing often suffers a bit, because we write knowing that it has to be accepted When we write solely to release our candid, sincere thoughts, and yes, Im including with fiction, we feel a sense of relief, release, and self-sustaining integrity. But we risk not making many sales. My suggestion is this . . . if you are writing as a career, then you must write somewhat for the public. However, somewhere along the way, write something that is yours. Write something that reconnects with your true being. Feel honorable and principled writing for one person, yourself. You never know . . . that might be your best work.

Home Building Industry in the United States Essay

Home Building Industry in the United States - Essay Example Housing is globally recognized as productive sector of the economy rather than a form of welfare, because "housing and economic development are closely linked" and it acts as an instrument to improve the GDP. (Housing for Economic Development, 2005). Because a healthy housing stock provides safety for employees, taxes for state and local governments, and more customers for retail and service business, house building industry helps state and regional economy to flourish. Every individual aspire to own individual dwelling unit and buying a home is a major life event. Major life events such as marriage, birth of a child, changes in employment, or retirement particularly influence the decision to purchase a house though mortgage rates, income and expected returns on investment also motivate their decision to invest in residential property. Young adults in the population constitute primary source for home buying and when there is upward trend to housing prices these first-time buyers will be more attracted to enter into homeownership under the notion that rising prices will make future purchases unaffordable. Housing is an important basic need and focus of social concern and should be viewed as one of the key elements of social policy. Some of the U.S markets may not have sufficient housing supply to accommodate the influx of new residents, while the state and local governments may lack the resources to provide supportive services. The ability of Americ a's working immigrant families to obtain decent and affordable housing has implications for the social and economic well-being of the United States. Studies found that there is a direct proportionality between housing price and homeownership, establishing that "housing market's volatility is amplified by buyers' responses to the trends in market fundamentals." (Myers & Ryu, 2008, P.17-33). Housing market provides "mechanism for equity growth, liquidity and financial flexibility for individual households, while also providing relatively safe, productive investments for institutions through secondary mortgage markets." (Housing for Economic Development, 2005). "Housing shortages have historically gone hand-in-hand with rising housing prices and rents, higher housing cost burden, lower homeownership rates, increased crowding, and longer commutes." (Landis, 2000). It is admitted that State's economy is one of the chief determinants of producing more housing units, because when the economy goes into recession housing demand falls quickly and deeply. "Economic recovery revitalizes the housing market, though expansionary peaks rarely even out the recessionary troughs." (Landis, 2000) According to Professor Michael E. Porter of Harvard Business School, "the only reliable test of economic value is sustained profitability, measured by superiority in long-term return on investment" and "industry structure is a key driver of homebuilder profitability". However, he asserts that "market assessments of homebuilding stocks appear to be out of line with other industries that have similar structural characteristics." (Porter, 2003). "The conduct of monetary policy by the Federal Reserve has profound impacts on the housing sector and its contribution to the overall economy" as reducing inflationary

African American Cinema Essay Example for Free

African American Cinema Essay The subject of African-Americans in Motion Pictures provides some of the most interesting studies along with the many controversial interpretations of the roles as actors they played on screen. As far back as the silent films era, African-Americans have been featured in motion pictures playing roles depicting some aspect of acting and being purveyors of a black image. The messages or themes of these movies have over the years presented a mixture of images based upon what was thought to please the viewers of each particular film. Unfortunately, many of those films showed black characters in negative stereotypical roles, which the average African-Americans would never truly identify as being like themselves. Since many of our American icons and heroes have come from our motion picture stars, we need to understand what this narrow view presented and compare it with what we presently see at our local cinema today. The movies Guess Whos Coming To Dinner (1967), Shaft (1971), Do The Right Thing (1989), Boys n the Hood (1991), and Menace to Society (1993) show a thematic style and stereotypes in the way that black films have progressed over the years. The motion picture industry was never too quick to change their approach in presenting African-Americans in realistic roles depicting social or civil conditions in an integrated context. Many of these roles required scenes showing African-Americans in positions of authority or relating to white Americans in a positive way. This Integration Period therefore brought together African-American actors with scenes along side white actors in roles showing both players dealing with racial conflict and resolution. Guess Whos Coming to Dinner was truly a unique film for its time in that Sidney Poitiers character breaks all the stereotypical views of blacks in American Cinema. In the early 1930s blacks were portrayed as lower class, slow-witted figures of entertainment, often showed in menstrual shows. Poitiers character broke all these stereotypes. 1971 brought to the big screen a successive series of superhero black or blaxploitation films. Shaft was released in 1971, and Richard Roundtree was the superman black hero detective. He was compared by many to the white James Bond. Related to Guess Whos Coming to Dinner, Shaft took it up a notch in showing a black man as a hero. Poitiers role was one to equalize whites and blacks in their roles in American cinema, but Shaft showed a black man who was an authoritative figure. Different themes can be mixed in between the two movies. They both show an intelligent black man that has a grip on reality. Both movies showed themes of how integration has struck America. They differ though on a level in that Shaft was a black dominant cast and Guess Whos Coming to Dinner was predominantly white. Do the Right Thing, Boyz n the Hood, and Menace to Society were all produced in a more modern era, hence the fact that they all have similar racial themes. The films all paint a picture of urban Black America in their time period. All three films are thought to be racially reactionary films aimed at the psyche of both black and white viewers. The movies were all a success due to the touched topics of racial situations, ethnic tensions, and human encounters of anger. The superb casts of both black and white actors made the motion picture industry aware of a newer avenue for films and race relations. African-Americans in motion pictures in todays expanding world of visual imagery can be seen on many expanding fronts. We see the making of motion pictures on subjects or themes which can be taken from history, life experiences, music, and unexplored events. Todays markets are open, and African-Americans are taking advantage of these open door opportunities. Actors and actresses are expanding their roles from stage acting to movies to TV miniseries to video cassettes or discs, and roles taken from books, plus movie soundtracks. In our world today African-American actors and actresses will always have a place in American Cinema and their future looks bright and promising.

Appearance Versus Reality in Katharine Anne Porters He :: Katharine Anne Porter He Essays

Appearance Versus Reality in Katharine Anne Porter's He So many memories came to my mind while reading this story! I grew up in a family (or at least one side of that family) who always cared and worried about what other people thought! Most obviously, the short story, "He," by Katharine Anne Porter is about appearance vs. reality and living with a disabled child. But I also believe the story is about life, the hardships of life, poverty, the innocence of children, the trust children put into their parents, the gossip of small towns, the resentment and bitterness of the hardships of life, being a mother, rural life, denial, guilt, and compassion. Most importantly, however, I believe the story is mostly about the resentment of the hardships of life and appearance vs. reality. Edgar Allan Poe once said in his "Twice Told Tales" that a writer must give her "single effect," or thesis, in the first sentence of a story or they have made a mistake. So, I always look at the first sentence of a story when I read it to see what themes it provokes. The first sentence in "He" is: Life was very hard for the Whipples (324). Throughout the story, we get a building up of just how "hard life was for the Whipples." Through all these hardships, Mrs. Whipple seems to be resentful of every problem the family must overcome. Instead of supporting her husband and her children she complains about everything and seems to worry only about herself. For example, one of the first instances of Mrs. Whipple's true feelings of resentment of having a disabled child (and the burden that creates) comes when she butchers the pig. After she slits its throat, He runs away and Mrs. Whipple thinks to herself "with a stiff face": He'd eat it all if I didn't stop him. He'd eat up every mouthful from the other two if I'd let him (327). Here, I believe Mrs. Whipple's tone is very resentful that she has a disabled child that cannot think for or take care of himself. Mrs. Whipple must always take care of Him first before anyone else since he cannot fend for himself. She "gets tired trying to keep [Him] decent" (327). This scene also shows how resentful Mrs.
