...parameters were not as clear-cut as they should have been . My signing speed was fairly descent, I try to go at a paste, which I am comfortable with, so that I will make the least amount of mistakes as possible. My signing production was terrible, I froze up so many times even though I really did know how to sign the correct questions. For example instead of signing university I signed school. Also I noticed that when signing I left out accurate meanings of words such as our and we that I mixed up. Many of my signals were not complete so I noticed that I need to assure that I completely finish a sign, and then move on to the next one. 2. My non-grammatical signals were off only because I looked down at my paper so much. But I noticed I was using them, but you could barley see them because you could not see my eyebrows. The only time you really seen my non-grammatical signals was in my introduction. There were several times for example when I would start a sentence you could see my non-grammaticals but towards the end of the sentence I noticed I was to worried about trying to figure out how the rest of the sentence was structured. Some of my non-grammatical signals had no emotion, I need to either smile more or make it more noticeable that I’m trying to express a word. 3. After viewing my expressive test and comparing it to the model video I noticed there is still a lot of work that I need to improve. I need to speed up my performance as well as my sentence structure.......

The salary conditions were a stumbling block for this particular exercise. With the knowledge of being the manager, I knew that I had other qualified individuals that could be offered the position. The scenario explained that RR already offered a high beginning salary for a new employee. I felt that someone fresh out of college did not warrant a higher salary. In general, I do believe that salary can usually be negotiated. For the majority of jobs (not retail, fast food, etc…), employers give a range of what the salary can be. For the federal government, salaries are usually locked in but you might be able to negotiate at what level you start. ▪ What other things are negotiable? If salary is locked in, there are always other options. For the exercise, we looked at offering relocation costs, a signing bonus, stock options and even starting dates. All these things can be talked about......

Bg vs. Lc

...Bank guarantee Vs Letter Of Credit A bank guarantee and a letter of credit are similar in many ways but they're two different things. The main difference between these two credit security instruments is the position of the bank relative to the buyer and seller of a good, service or basket of goods or services in the event that the buyer defaults. These financial instruments are often used in trade financing when suppliers, or vendors, are purchasing and selling goods to and from overseas customers with whom they don't have established business relationships. A bank guarantee is a guarantee made by a bank on behalf of a customer (usually an established corporate customer) in case it fails to deliver the payment, essentially making the bank a co-signer for one of its customer's purchases. A guarantee is a written contract stating that in the event that the borrower is unable or unwilling to pay its debt to a merchant, the bank will act as a guarantor and step in to pay that debt. The initial claim is still settled primarily against the bank's client, and not the bank itself. This is a type of contingent guarantee. A bank guarantee is more risky for the merchant and less risky for the bank. But this is not the case with a letter of credit. While a letter of credit is similar, the principal difference is that it is a potential claim against the bank, rather than a bank's client. For example, a seller may request that a buyer be provided with a letter of credit, which......

...situation. We all have seen whites before but have never had much to do with them. But the ten white girls we encounter at the camp are closer to us and, therefore, more real and capable of exciting envy and hatred. At the end of the first day at camp, Arnetta reports she heard one of the white girls refer to Daphne, a black girl, as "a nigger." On prompting by Arnetta, Daphne, a quiet girl, nods her head to confirm that the derogatory term was used. Arnetta tells the other girls that they cannot let the white girls get away with using that word about them. She told us that we must teach the white girls a lesson. Janice suggests that they put daddy-long-legs in the white girls' sleeping bags, and when the girls awake, beat them up. Arnetta told Janice, to shut up and then announced that we are going to hold a secret meeting. She then turned to me and asked if I had plans to tell Mrs. Margolin, who was our troop leader, about the situation. On the second day of camp, our troop ate our sandwich lunch by a stream that borders the field hockey lawn. Arnetta, for some reason, eyed the white...

...How Businesses Are Organised and Their Purposes Division of work Work is divided up in the Coca Cola business because this makes it much easier for employees so that they can get the job done. This takes out conflicts between individuals opinions towards the work they are working on. This will mean that no one can say anything about each other’s work and they can do the work in piece without any contribution from others unless it is wrong that needs to be improved told by the manager. Lines of control This means that if Coca Cola Company knows what they are doing and they can control the activities being done. The heads of Coca Cola set task to the senior managers then they do the same thing setting the task to the employees. The task is divided up in the different sector such as finance would do the finance task and marketing will do marketing task. This way everything can be controlled easier rather than one person doing it all which is impossible to do every sectors job in a large company like Coca Cola. Communication In Coca Cola the communication are set from the top to the bottom. The directors of Coca Cola will tell the managers what task have to be done then they will tell the employees what has to be done too, this can sometimes go wrong as the message is getting passed by a lot of people in the business. Sometime the communication is passed from bottom to top because if something goes wrong in the factory of Coca Cola the employees will have to inform......

Coca Cola Marketing Continuum

...so many products and services that cost a fortune it is hard to even evaluate a distinct price. Offering retailers that retail Coca Cola a competitive price that ensures they will make profit while the company does as well will get a more financial sound base for selling Coca Cola. Encouraging a competitive retail wholesale to stores and restaurants will offer more companies and places to offer the Coca Cola brand rather than Pepsi if they only own a certain brand. Meeting and going over a company’s expectations and offering valuable discounts brings more buyers and better relationships from seller to buyer in the long run. The economy regulates prices and the fact that someone can pinpoint how much something is and relatively cheap brings up moral from buyers. Offering a company cheap rates and alternative promotions like a free pallet of Coca Cola, after so many are bought and shipped to the store can be a price focus and which would also stimulate Interdependent relationship. With the right price and price focus the Coca Cola Company can prove to their retail buyers that they can competitively price and offer a low rate for Coca Cola in turn building a level in the marketing continuum with their buyers. The Price focus can also provide the Coca Cola customer with a better view on their product. Low prices and sales on Coca Cola drinks is the first...

Shot-by-Shot Analysis of a Film

...Shot-by-shot Analysis Life of Pi, a 2012 American 3D adventure drama film that composed of live -action and computer-animated adventure based on Yann Martel's novel. This film is directed by Ang Lee, a movie that tells a story within another story based on one simple truth. In the movie, the narrator pi, who was the only survived young man from the sinking Japanese ship caused by the storm. He made to the lifeboat, yet, he was alone in the center of pacific ocean without any supplies but with a tiger called Richard Parker. However, the theme of this film is not just this exciting adventure but is the implicit conflict between Pi and the tiger; Pi’s rationality of believing in God to the animality aspect of his personality, the animalistic side of human nature that he struggled with. Every scenes have highlighted this meaning of how they survived as a whole. However, I found the sequence of when the main character Pi has his emotional changes from fear tiger to kill tiger to the end of living with the tiger is interesting and it reveals the overall meaning of the theme of the film as well. In this particular sequence, the camera has used long shots repeatedly and frequently to align the audience with the filmed characters and with their feelings. The long shot in the looser framing and the wider angle of vision create sense of negativity between Pi the powerful and isolating environment of the ocean. In a image of this sequence, long shot of Pi catching fishes with his tools......
