Journeys End

...Journeys End Critics …… English literature Frank Scheck - Reuters “Arriving on Broadway years after its triumphant West End production, this revival of the little-seen (at least in America) "Journey's End" demonstrates that this 1929 World War I play by R.C. Sherriff, rather than being a museum piece, has lost none of its power or immediacy…” “Running nearly three hours, the play doesn't contain much in the way of incidents, instead stressing the constant fear and stress permeating the soldiers' day-to-day existence. Eventually, Osborne and Raleigh are assigned to undertake a dangerous mission, the result of which vividly conveys the senseless tragedy of war…” “Everything about this deeply stirring production, including the final visual tableaux and even the somber curtain call, has been rendered with a sensitivity and craftsmanship that represents theater at its finest.” http://www.justinblanchard.com/Reviews/Journeys/JE_Reuters_Review.pdf John Simon - Bloomberg.com “Who says perfection is not within human reach? Go see “Journey's End” and learn otherwise. R.C. Sheriff's play about World War I has not been staged in New York in 70 years, which is at least 50 or 60 too many…” “Every bit of the masterly dialogue rings as true as the bombs, cannons and machine guns outside. Experiencing “Journey's End” is more than mere theatergoing; it is living a life you haven't had, while making the one you have incomparably richer.” http://www.justinblanchard.com/Reviews/Journeys/JE_Bloomberg_Review...

Childhood End

...Childhood’s End Arthur C. Clarke The opinions expressed in this book are not those of the author I EARTH AND THE OVERLORDS Chapter 1 The volcano that had reared Taratua up from the Pacific depths had been sleeping now for half a million years. Yet in a little while, thought Reinhold, the island would be bathed with fires fiercer than any that had attended its birth. He glanced towards the launching site, and his gaze climbed the pyramid of scaffolding that still surrounded the “Columbus”. Two hundred feet above the ground, the ship’s prow was catching the last rays of the descending sun. This was one of the last nights it would ever know; soon it would be floating in the eternal sunshine of space. It was quiet here beneath the palms, high up on the rocky spine of the island. The only sound from the Project was the occasional yammering of an air compressor or the faint shout of a workman. Reinhold had grown fond of these clustered palms; almost every evening he had come here to survey his little empire. It saddened him to think that they would be blasted to atoms when the “Columbus” rose in flame and fury to the stars. A mile beyond the reef, the “James Forrestal” had switched on her searchlights and was sweeping the dark waters. The sun had now vanished completely, and the swift tropical night was racing in from the east. Reinhold wondered, a little sardonically, if the carrier expected to find Russian...

Journeys End Importance

...Journey's End, a play based on the author, R.C Sherriff, experiences, portrays the condition of the First World War. The characters in the play each symbolized different aspects or ideas different people had when facing the same situation in the trenches. In the play, Osborne's role is very important because he showed the feeling of calmness despite any conflicts that were going on. His reaction to the war, his relationship with Stanhope, and how he settled down the conflicts between other characters in the play supported this. Osborne dealt with the war situation, the real physical conflict in the play, in a more mature way than any other characters. Besides from being the oldest, "about forty-five", and the most experienced, Osborne is married and has two children. He spent most of his free time in the trench reading "Alice in Wonderland" and he talked about "making a rockery" and gardening during his civilian life. This showed that he is rather a family man. Osborne said that he looked at the war in a "romantic" way; there is no point of looking at things in a "black sort of way" because everything will seem to be even worse for him. He seemed to be the one that spend the time in the trench usefully, at least more useful than Stanhope's "drinking" and Trotter's circle drawing. He joked around about the big attack with Hardy at the beginning of the play and about food with Mason throughout the play, not trying to be too serious about everything. This characteristic of Osborne...

Lands End Case Study

...Lands’ End Case Study Shawan M. Fisher, MPA Management Information Systems Texas Southern University Fall 2015 September 30, 2015 Discussion of Company In 1963, Gary Comer, an advertising copywriter with Young & Rubicam, decided to pursue his dream of opening his own business. With $30,000 of initial funding, Comer and his partners Robert Halperin, Richard Stearns and 2 of Stearns employees set out to open Lands’ End. The first store was located in Chicago IL. and initially offered sailing equipment. Comer was an avid sailor along with Richard Stearns who was also a sailor.

In the spring of 1977, Lands End produced its first catalog containing apparel and other goods. That same year, sales reached $3.6 million. In 1978, the company introduced its first button-down Oxford shirt upon which the Lands’ End legacy would be built. Also in 1978, operations were moved from Chicago to Dodgeville, WI. Another significant shift in operations at the time was the introduction of fulfilling customers’ orders by telephone. Lands’ End set up its toll free 800- number ad staffed it with eager operators who were answering customers’ calls in less than 2-rings! With clothing offerings soaring, the company broke ground on an office building and a 33,000 square-foot warehouse in 1979. By 1980, Lands’ End...

End User Computing

...End User Computing (EUC) refers to systems in which non-programmers can create working applications. EUC is a group of approaches to computing that aim at better integrating end users into the computing environment. These approaches attempt to realize the potential for high-end computing to perform in a trustworthy manner in problem solving of the highest order. Partly as a result of the development of high powered desktop computer and user friendly languages, there is a trend to assign both program development and actual computing to user. Instead of centralized group completing development of appropriate application, user will develop the program. The role of the experts is to provide users with the tools that enable them to develop their own reports and application and also to serve as a technical consultant. The EUC Ranges section describes two types of approaches that are at different ends of a spectrum. 1. The first approach would have canned queries and reports that for the most part would be invoked with buttons and/or simple commands. 2. For the second approach, SQL administration would allow for end-user involvement at several levels including administration itself. Between these two extremes view of EUC there are many combinations. Some of the factors contributing to the need for further EUC research are knowledge processing, pervasive computing, issues of ontology, interactive visualization EUC might work by one type of approach that attempts to integrate...

...Defining Characterization Characterization is the process by which the writer reveals the personality of a character. Characterization is revealed through direct characterization and indirect characterization. Direct Characterization tells the audience what the personality of the character is. Example: “The patient boy and quiet girl were both well mannered and did not disobey their mother.” Explanation: The author is directly telling the audience the personality of these two children. The boy is “patient” and the girl is “quiet.” Indirect Characterization shows things that reveal the personality of a character. There are five different methods of indirect characterization: Speech Thoughts Effect on others toward the character. What does the character say? How does the character speak? What is revealed through the character’s private thoughts and feelings? What is revealed through the character’s effect on other people? How do other characters feel or behave in reaction to the character? What does the character do? How does the character behave? What does the character look like? How does the character dress? Actions Looks TIP #1: TIP #2: Use the mnemonic device of STEAL to remember the five types of indirect characterization Use indirect characterization to analyze visual media: Film: Look at how the character dresses and moves. Note the facial expressions when the director moves in for a close-up shot. Drama: Pay attention to the way that the characters reveal...

Cat or Mouse

...Cat or Mouse Along the novel the symbolic figures of the cat and the mouse, are named constantly. The cat mainly represents the persecutor, the repressor, while the mouse represents the victim. The cat in the novel represents, for instance, the Nazis and the mouse, the occupied and humiliated Poland. Pilenz and Mahlke also represent both animals: Pilenz the cat as direct or indirectly contributes to Mahlke's destruction, and then again the love and hate relationship that he feels towards Mahlke creates in him such dependence that later turns him into the mouse. Mahlke is the mouse. An animal which is also represented by Mahlke's apple of his throat because he is eternaly humiliated even though he keeps trying to be accepted by the Nazi society all the time, making all kind of feats to pay people's attention. Mahlke is also a cat because of the feelings of dependence and of inferiority that he awakes in Pilenz. The reader is not expected to share Pilenz admiration for Mahlke', due to the way Pilenz tells Mahlke's story. One may have a feeling that, when reading Pilenz's words, Mahlke's attitude is sometimes irritable, egocentric, and so on, despite often the fact that Pilenz wants to deny those feelings which we perceive that he shows. Many times the group of friend’s joke and laugh at Mahlke, including Pilenz: “We laughed as, bluish and shivering, he crossed himself with his waterlogged fingertips, attempted to move his lips in prayer and produced a bit of Latin between chattering...

Through the story, the family ends up meeting with the murderer and identify him as Mistif.

...The quote is most evident in when anyone is given a certain task, that person then takes on the responsibility of having to accomplish that task. For example, when a carpenter gets a customer that wants new cabinets in their kitchen. The carpenter then has to complete the requests of the customer, doesn’t matter how he gets the job done, but as long as the cabinets are completed. He could get his five workers to complete the job, or he could do it himself with his two top carpenters. The task is given first and it does not matter how or who gets the task done but as long as the cabinets are complete. In the end when the customer sees the final product they will be happy either way, which is where the “[who cares] “in the quote comes into play. The cat does its job in the household by catching the mice, it doesn’t matter what type of cat. Just like building cabinets, in the end as long as the cabinets are what the customer asked...

Decision Making Process

...learned about the INROADS program, a non profit organization that places minorities into internships at a corporate level. I participated in this program and I was taught how to interview and given several mock interviews. Once I completed all of these interviews I passed onto the corporate interview phase where I interview with major companies like IBM and AT&T. During the interviews I learned about both positions and at the time, Project Management/Frond End Developer and Software Engineer both sounded like good positions. I know long term I wanted to do something with mobile application development so the contribution of both positions would put me closer to my goals. After my interview I was offered positions at both companies so of course I had to decide between the two. With a five day grace period a decision had to be made quickly. Being a Software Engineer would provide me with the skills I needed to do mobile application development on the back end, in other words, “coding”. The role of a Front End Developer or Project Manager would assist me in developing the user interface or user experience of mobile applications. It would also help me learn the different methodologies and approaches to application development. The position at IBM would require me to move to Durham, NC and the position at AT&T required me to relocate to Atlanta, Georgia. If I took the position in either place I would have to sublease a home for the summer. This would mean I needed to...

Organizational Behaviour

...Maria Nathan Writing Assignment-1 Strategic Design at Dynacorp 1. If you were on the Dynacorp task force, what would be your first choice for an alternative design? What would be your second choice?. Answer: If I am on the Dynacorp task force, my first choice for an alternative design would be front /back structure of strategic design. This structure divides the organization into two parts such that the back end products which include engineering, manufacturing and the logistics and the front end is faced by the marketing and sales division. As Dynacorp is spread across the US and as well as the world, this front/back structure will also support the various divisions spread across the globe. Each country where Dynacorp wants to expand itself can have its marketing and sales division and the manufacturing division can be located in a country where the production costs would be as lower as possible. This would be an advantage by lowering the production costs and increasing the profit of Dynacorp. The marketing division, which becomes the back end of the structure, can address the various issues faced by the Dynacorp, with one major issue of handling the change from dealing with the direct customers to the consulting firms with special practices in ITC. This can be coordinated with the engineering and the production divisions, which in turn spread across the globe. With the advancement in the information exchange systems, the communication between the divisions can...
