Design Flaws on the Titanic

Design Flaws on the Titanic The sinking of the Titanic is one of the most well known sea disasters to date. It has had numerous songs, movies, books, and even a cruise planned in its honor. There were 2340 people aboard the ship when it set sail across the Atlantic on its maiden voyage. When it sank, there was a total loss of life of 1635 people (Myers 17) Not only are there several theories about the cause, there are several changes that came from the sinking of the Titanic that range from modifying the designs of the ships, regulations on type of materials used, and better laws and regulations for safety and communications. This disaster has affected the world as a whole, as there were people from different countries and social status that lost their lives in the disaster. In 1904, Trans-Atlantic British ships were all fitted with the radio equipment created by Guglielmo Marconi. The operators for these were previous operators from railroad lines and the postal telegraph. In England, the general call on land lines was CQ. When the wireless progressed to sea this became CQD signifying CQ general call, D distress. The Titanic first used CQD with the Titanics call letters MGY. Later, they would use this interspersing it with the newly created distress code of SOS. (McEwen) When the Titanic set sail it was equipped with the best available electrical generators and radio equipment for the wireless by Marconi Company. Which was the dominate provider of radio equipment and operators. It had 5 kilowatt motor generator with an emergency generator and batteries. The radio had a guaranteed range of 250 miles under any weather and could maintain communications over 400 miles. The antenna was four wires stretched between two masts with a height of 205 feet above sea level. This was fed by four individual wire feed lines. (Johnson) On the night of the 14th, the two operators, Jack Phillips and Harold Bride, were going through the backlog of communications due to radio equipment problems. The first message received mentioned ice. By 9:30PM, they had received various reports of the dangerous ice. They only responded with Thanks and continued on. By 10:55, the Californian said that they were stopped and surrounded by ice and they were told to shut by Phillips, and that they (the Titanic operators) were busy with Cape Race. (Cape Race Wireless in Newfoundland). However, Captain Edward J. Smith of the Titanic ordered the change in course based on four of the received messages. Three warnings were received from the crows nest. (Myers 46) Even fifteen minutes before the Titanic struck, the lookout men had reported seeing an iceberg. No attention was paid to the warnings. (Myers 47) This was at 11:15pm. Murdock, the officer in charge of the bridge, was accused of being tardy in answering the call from lookouts. That without his tardiness, the Titanic could have averted the disaster, allowing her to turn enough to hit the iceberg with her stern. (Myers 48) It was also noted that disaster could have been averted had the lookout men in the crows nest been equipped with binoculars. They had requested these in Belfast, only to be turned away empty-handed. The Titanic was 900 ft long, 25 stories high, and weighed 46, 000 tons. It was created with turn of the century design and technology. It possessed 16 major watertight compartments in the lower section of the boat. These were easily sealed off if the hull was punctured. In the worse accident at sea (two ships collide) the Titanic should have been able to stay afloat for 2-3 days allowing time for resue. (Bassett) However, after the collision with the iceberg, the hull part of 6 of the 16 compartments were damaged. They sealed off the compartments but when the bow of the ship pitched forward from the water weight in that area, the water spilled over into the other adjacent compartments. They were only watertight horizontally, the tops were open and the walls extended only a few feet above the waterline. (Bassett) These compartments are what caused the general belief that the Titanic was practically unsinkable. However it is found that without those compartments the water would have sp read out, preventing the bow from weighing the ship down below water level. The White Star Line modified the Titanic sister ships, Olympic and Britannic, by extending the double bottoms up the sides of the hull, and the transverse bulkhead compartments were raised. (Garzke and others) In addition to the design flaws, it was found that the hull steel and wrought iron rivets failed due to brittle fracture. This is a type of failure in structural materials that occurs without prior deformation and at extremely high speeds. Brittle fracture is caused by low temperatures, high impact load, and high sulphur content. At the night of the collision, all three causes were present. (Bassett) Scientists recovered a piece of the hull steel and noted that the edges were jagged and sharp, shattered as if it was china. The metal showed no evidence of bending or deformation. High quality steel is more ductile and will deform rather than break. (Gannon, 1995) The steel recovered from the Titanic was given the Charpy test This is where a cigarette sized coupon of steel from the wreck was held against steel backing and struck with a 67lb pendulum on a 2 ÂÂ ½ ft long arm. This was compared with modern steel and they were placed in a alcohol bath at -1ÂÂ °C to simulate the co nditions of the disaster. The modern steel bent into a v, wereas the Titanic steel pinged, the pendulum barely slowed and the broken piece flew across the room (Bassett) The wrought iron rivets in the hull were also have shown to fail due to brittle facture. In addition to that design flaws, tests have shown that lesser quality iron rivets when they hit the iceberg, the weaker rivets in the bow popped, opening the seams in the hull (Hooply-McCarty and Foeck) From the beginning of the voyage, there were not enough lifeboats for the amount of people on the ship. If the lifeboats were filled to capacity, they would fit 1100 people( Myers 17) The designer had allowed room on deck for 2 rows of lifeboats. One row was removed in order to make the deck ascetically pleasing.(Bassett) The British Board of Trade regulations at that time stated that all British vessels over 10,000 tons must carry 16 lifeboats with a capacity of 5,500 cubic feet, plus enough rafts and floats for 75% of the lifeboats. These were obviously out of date as steamships had greatly grown in size proven by Titanics 46, 000 tons. Actually, The White Star Line had provided 20 lifeboats which was more than required by law, but inadequate for the amount of passengers on board. There were multiple changes in the laws and regulations after the Titanic disaster. After the Titanic sank, they strengthened the laws governing the use of radio equipment on ocean liners. (Gale Group 199 9) There were new established safety regulations. The US government also began ice patrols to alert the English and US boats of approaching ice fields, they made sure the lifeboats were supplied properly, and change the requirements regarding lifeboats. Up to this point, lifeboats were based on tonnage, and this was change so that every person aboard the ship had a seat on the lifeboat. They also established lifeboat drills that were held once the ship sailed. (Visible Ink Press) The Titanic barely made a noise when it struck the iceberg. Large amounts of the passengers had already gone to bed. Stewards and other members of crew were sent to arouse the people. Some refused to get up. The crew almost had to force the doors of the staterooms to make them appreciate their peril; many were drowned like rats in a trap.(Myers 53) The slight lean the ship had as it was sinking, contributed to a larger loss of life, as few could believe that there was danger, and this resulted in the passengers going back to their various activities, or going to dress. Once on the deck, many hesitated to enter the swinging life-boats. The glassy sea, the starlit sky, the absence, in the first few moments of intense excitement, gave them the feeling that there was only some slight mishap; that those who got on the boats would have a chilly half hour below and might, later, be laughed at. (Myers 57) The call was put out that the lifeboats would be filled with women and children first. This caused a panic as many women clung to their husbands and refused to be separated. A number of steerage passengers were yelling, screaming and fighting to get on board. Officers drew guns and told them if they moved towards the boats they would be shot dead. (Myers 59) However, once on the lifeboats, it was discovered that there was a lack of necessary equipment. The boats were filled 1/3 to capacity, with no supplies, no way to raise sails or operate sailboats. (Myers 72) Several of the lifeboats would return to allow some fo the survivors ot climb into the lifeboa ts, escaping from the freezing water. The RMS Carpathia was the closest ship to the disaster that responded, and would be the one that brought the survivors to New York City. The total loss of life would amount to 1635 people. (Myers 17) From these survivors, a large portion of these are children from first and second class. Only 27 children were saved from the 79 total of third class passengers. This could also be contributed to the language barrier due to the large amount of foreign third class passengers. There were a total of 425 women aboard the ship, from first, second, third class, and crewmembers. Out of these, 316 survived. The majority loss of life, also coming from the third class passengers. Only 338 men survived the sinking, this is out of all 1352 men aboard. This is partially due to the women and children first rule. At the time of voyage, there were a variety of the rich and powerful on the Titanic. These included: John Jacob Astor IV and his wife, Madelein, Macys owner Isidor Straus, and his wife, Ida, silent film actress, Dorothy Gibson, the Countess of Rothes, Denver millionaire, Margaret Brown, Sir Cosmo Duff Gordon, and his couturier wife, streetcar magnate, George Dunton Widner, Pennsylvania railroad executive John Borland Thayer and his 17yr old son, and U.S. presidential aide Major Archibald Butt. When news of the Titanic spread, the resulting panic insued because of some of the worlds movers and shakers were on that boat, and the public worried about how this would effect them. The Titanic is one of the great sea disasters to date. The resulting loss of life and loss of large amounts of money, mail, and various riches that couldnt be replaced, or retrieved. There are no survivors left of this disaster, however to this day, Belfast mourns the loss of 123 people from Lebanon traveling on the Titanic along with mostly European passengers and Asian crew. Every year they lay a wreath to commemorate the loss. (The Irish Times.) The ultimate cause of the Titanic sinking was from striking an iceberg on its voyage from Belfast to its ultimate destination of New York. During the time they were crossing the North Atlantic, they were also battling a coal fire in one of the bunkers. It was assumed that the crew was attempting to break speed records at that time. However, the ship was built for comfort, rather than speed. And in further investigation of reports from surviving crew, the fire has become another factor as to why ship was moving so fast after reports came in about the ice fields in an area of the North Atlantic that made the travel distance shorter from the original planned route. If there was a reason for speed, it had to be something important, like a fire in a coal bunker that neede to be kept under control and put out as soon as the ship reached port.(Science Daily) The multitude of complications that arouse from this maiden voyage changed history from the large loss of life. This could have been avoided with simple precautions, and a more realistic idea of the unsinkable Titanic. The communication issue on the Titanic is what pioneered the wireless world today. The new regulations for ships at sea, resulted in more and better equipped lifeboats and ice patrols in areas known for ice fields. The designs and materials used for the ships were changed to allow for safer ships, preventing the shattering of steel or water weighting down the ship. Without this disaster, would we have progressed this far so fast?

Contiki Tours : Marketing Strategy Analysis Essay

Contiki Tours is an organisation that offers packaged holidays to a variety of local and international destinations. Their targeted market is limited by age. Clients must be between 18 and 35 years old. The analysis will focus on Contiki *s Australian market for international holidays. Contiki have adopted a concentrated marketing strategy in identifying market segments. This means that they have elected to focus their marketing efforts on gaining a high share of one particular segment of the market (i.e. 18-35 year olds). The advantage of such a strategy is that it allows specialisation which may produce economies in production, distribution and promotion. However, it does entail some risks in that market needs can change or competitors may enter the segment. The risks and benefits of this strategy will be examined more closely in the analysis of the marketing mix. Product In order to assess the effectiveness of Contiki’s marketing strategy it is important to understand the n ature of the product offered by the organisation in terms of the benefits that it provides. Broadly, it is a service product (eg. flight, bus trip, food preparation) although elements of the product are physical (eg. food, t-shirts). It is a specialty product given that it meets a specialised need and consumers are willing to spend quite some time searching for and evaluating. It is also purchased infrequently. It would also be considered a high involvement product due to the relatively high risks of purchase. The notion of purchase risk will be explored in more detail in an analysis of consumer behaviour. Price The nature of the product, characteristics of the target market, and consumer behaviour each have important implications for pricing. It should be noted that the price paid for the product by the consumer involves more than the nominal price (i.e. the ‘price tag’). As well as the money paid for the product, consumers endure time costs and must expend behavioural and cognitive effort. Cognitive effort may involve the customer dealing with some of the risks of purchase (Ross, 1984). There are a number of implications of this analysis for Contiki. Firstly, the organisation can manage the price t hat consumers pay by minimising the time, behavioural and cognitive effort that is used purchasing the product. By decreasing the costs to the consumer, Contiki is able to increase the perceived value of their product to consumers. Over-the-phone or internet information and booking services would decrease the time taken in actually purchasing the product, and therefore the cost of the product to the consumer. Also, convenient agent locations would minimise the behavioural effort for consumers. Contiki attempt to coordinate with a wide range of travel agencies who are educated by Contiki sales staff on product attributes (the distribution channel and its implications for pricing with be covered more thoroughly in a later section of this analysis). It should be recognised, however, that many consumers derive utility from extensive cognitive involvement in the purchase process. For example, some customers may enjoy discussing at length with consultants, their itinerary and travel options. To the extent that this occurs, friendly and knowledgeable travel consultants should be an integral part of Contiki’s product offering. In order to achieve this, promotion (i.e. personal selling) to the distribution channel should be emphasised. From this discussion it is evident that the interaction between consultant and customer is a key aspect of the value delivery sequence. Increasing perceived value involves managing the people or participants in the consumption process (Berry, 1980; Booms & Bitner, 1981).

Features of Natural Moral Law & Dicuss Whether Its Strengths

EXAMINE THE KEY FEATURES OF NATURAL MORAL LAW & DICUSS WHETHER ITS STRENGTHS OUTWEIGH ITS WEAKNESSES Natural Law has roots that stem back to Ancient Greece, and it was Aristotle who really created the approach. It was also depicted in Sophocles’ play Antigone, where the protagonist claims her right to bury her brother despite the King (Creon) ordering that he be fed to dogs. Antigone, (the protagonist) proclaimed this because she believed that there was a higher law than the King’s, particularly, Natural Law.However, it was not until the 13th Century until Thomas Aquinas developed its key features, that it was actually more widely recognised as a moral theory. When we focus on the recipient of the natural law, that is, us human beings, the proposition of Aquinas's natural law theory that comes to the forefront is that the Natural law establishes the basic principles of practical rationality for human beings, and has this status by Nature. These are to be followed univer sally, as Cicero puts it; it is ‘one eternal and unchangeable law will be valid for all nations and all times’.According to Aquinas, all humans seek good and when we do wrong or evil, it is only because we are only seeking ‘apparent’ goods and not real goods. So, we could ask ourselves, how does Aquinas define a ‘real’ good? A real good is when the said ‘good’ falls under the five primary precepts. These are: self-preservation and preservation of innocents, educating children, living in society, reproducing and worshipping God. Aquinas also believed that we can use our rationality to know Natural Law.It is inherent within our human nature, God reveals specific commands but these do not go against natural law but rather, further develop it. Aquinas said that a moral life is a life entirely followed ‘according to reason’. Aquinas allowed for the Aristotelian insight that the particulars of the situation always outstrip o ne's rules, so that one will always need the moral and intellectual virtues in order to act well. But he denies that this means that there are no principles of right conduct that hold everywhere and always and some even absolutely.On Aquinas's view, killing of the innocent is always wrong, as is lying, adultery, sodomy, and blasphemy; and that they are always wrong is a matter of natural law. Therefore, Natural law is absolute, but surely, we can ask ourselves, what about double effect? What if a dying mother had to give an abortion to preserve her life? For Aquinas, there are two key features of the natural law, features the acknowledgment of which structures his discussion of the natural law.The first is that, when we focus on God's role as the giver of the natural law, the natural law is just one aspect of divine providence; and so the theory of natural law is from that perspective just one part among others of the theory of divine providence. The second is that, when we focus on the human's role as recipient of the natural law, the natural law constitutes the principles of practical rationality, those principles by which human action is to be judged as reasonable or unreasonable; and so the theory of natural law is from that perspective the preeminent part of the theory of practical rationality.Whilst Natural law may be a particularly easy, universal theory that can apparently be followed by all people it has shortcomings. BEGAN FIRST WITH STOICS IN THE WEST THIS IS ONE OF THE FIRST ‘HYBRID THEORY’ HUMAN REASONING + DIVINE COMMANDS THE 13TH CENTURY WAS A GOLDEN AGE FOR CATHOLICISM, RULED BY THE IDEA OF REVELATION/FAITH/PRIESTHOOD THOMAS AQUINAS REASONED THAT WE ARE MADE IN THE IMAGE OF GOD THAT HE GRANTED US REASONING AND THAT WE CAN USE THIS REASONING THAT LINKS WITH PHILOSOPHY WHICH OVERLAPS WITH FAITH/DIVINE COMMANDS. REASON IS 1+1=2.AQUINAS SAID WE CAN USE HUMAN REASON TO PROVE THE EXISTENCE OF GOD. DIVINE LAW – THIS COMES FROM GOD. UNIVERSAL LAW = NATURAL LAW BROKEN DOWN INTO HUMAN LAWS. Ironically, all the primary precepts are about perpetuating the human race†¦ DOUBLE EFFECT STATES THAT IF IN ORDER TO GOOD YOU HAVE TO DO ‘LESSER/UNINTENDED EVIL’ ONE MAY PROCEED BUT IT HAS TO UNINTENTIONAL. NATURAL LAW DEFENDS THE JUST WAR THEORY – CAPITAL PUNISHMENT IS ALLOWED/JUSTICE WHAT ABOUT HOMOSEXUALITY? THEY’RE VIOLATING PRINCIPLE NUMBER 2 – PROCREATION BUT NEITHER WOULD BIRTH CONTROL OR CELIBACY.JUSTICE (LEGALISTIC)/EQUALITY/REASON-BASED/CONCISE IT CAN TELL YOU WHAT TO DO IN ALMOST ANY MORAL DILEMMA UNIVERSAL. IF THERE IS A GOD, JUSTICE WILL BE ASSURED. THEREFORE, EVEN IF YOU SUFFER BY FOLLOWING NATURAL LAW, BALANCE WILL BE DEALT. GOD MAKES SURE THAT THE INNOCENT ARE VINDICATED AND GUILTY ARE PUNISHED. CONS: NO GRACE, MERCY OR FORGIVENESS ALLOWED. ‘AN EYE FOR AN EYE, A TOOTH FOR A TOOTH’. A LIFE FOR A LIFE BECAUSE IT IS A REASON BASED THEORY, IT CAN BE RATIONALISED AND CAN BE SUBJECTIVE.BY USING DOUBLE EFFECT YOU COULD RATIONALISE ALMOST ANY BEHAVIOUR YOU WANT. BIRTH CONTROL IS A BAD THING. BUT WHAT ABOUT IN AFRICA, HIV/AIDS ETC. EFFECT YOUR SELF PRESERVATION. PERSONAL OPINION OF NATURAL LAW – IT CAN BE MASSAGED INTO JUSTIFYING ALMOST ANYTHING BY THINKING ABOUT IT. I LIKE AQUINAS I LIKE ITS SIMPLICITY BUT THE WORLD IS NOT THAT NEAT AND TIDY, THE RULES ARE TOO VAGUE. I DON’T WANT TO LIVE IN A WORLD WHERE THERE ARE NO SECOND CHANCES. ‘AN EYE FOR AN EYE WILL LEAVE THE WHOLE WORLD BLIND. ’

Police Brutality And Ways Of Reducing It Essay - 2246 Words

Analyzing Police Brutality and Ways to Reduce it Abstract: Police use of force is a controversial topic in today’s society. It is now happening at a dramatically increased rate in some of the finest police departments in the United States. As an integral part of police work, officers are tasked with detaining individuals who break the law. Part of detaining those individuals, officers use discretion when determining the amount of force to use on a suspect if they become too resistant. But many of those officers are using unnecessary force against those suspect in fear of their safety. Those officers use physical force which often times becomes police brutality. Officers are often not held accountable for their actions because their actions are always deemed as justifiable. But how many of those cases are not justifiable to their actions? Even when the proof is there they are not held accountable. Many researchers have conducted research how and why these problems have occurred and the possible solutions. In this paper, I pla n to review and advance on what can be done to reduce police brutality. Looking at six different sources relating to the research question. I have found that not all of the data in the articles is substantial enough to answers how we can reduce the occurrences of those situations. The research conducted is good enough but further research is needed to reach mitigation strategies for possible solutions.
