GI Jane - Movie Review Example As a Navy topographic analyst, O’Neil was determined to prove that women would be able to adhere to the rigorous training, where even men reportedly fail. The film shows the manner by which O’Neil struggled to emphasize and prove that she can comply with all the physical, emotional and mental demands of the training. Shaving her hair to ultimately depict her demand to be treated as a soldier, not as a woman, O’Neil braved exerting her physical limits under different weather conditions: doing push-ups under ice-cold surf, training under the rain, crawling through muddy ground, being resourceful for food from trash, and being subjected to all sorts of physical torture (getting punched, kicked, shot at). O’Neil was also constantly being mentally and emotionally barraged by her drill trainer, Master Chief John James Urgayle, portrayed by Viggo Mortensen. Due to O’Neil’s remarkable persistence and success within weeks of training, she was termed â€Å"G.I. Jane† by the civilian media The climax of the film finally tests O’Neil’s preparedness to go into combat through a mission in Libya where she commandeered a platoon to rescue a team of U.S. Rangers who were set to recover a satellite with plutonium that fell into the Libyan dessert. O’Neil’s skills and leadership enabled her and the team to rescue her Master Chief who got injured and, therefore, rendered her worthy to be accepted among the Navy SEALs. The clearly explicit backdrop of gender discrimination in the Navy was the ultimate example that formed the plot of the film.The initial recruitment of O’Neil in the program was a form of test to prove that women can indeed succeed in the rigorous training predominantly dominated and passed by men only. Another example of discrimination is the initial perception of the male trainees on O’Neil, who sneered and expected her failure just because of her gender. The stereotyped perception

Thermography technique - Essay Example Thus a complete surface temperature map of the object can be obtained in a non-contact manner. With appropriate calibration, it is also possible to get the absolute temperature values of any point on the surface of the object. Standards are required for calibration and these standards are materials of known emissivity in the temperature range of calibration. Infrared refers to a region of spectrum between the visible and microwave. The infrared spectrum extends from 0.75 mm to 1000 ?m wavelength range. However for practical applications it is the 1 – 15 ?m wavelength band, which is used. The properties of infrared radiations are similar to those of other electromagnetic radiations like light. These radiations travel in straight lines; propagate in vacuum as well as in solid, liquid and gases. These radiations can be optically focussed and directed by mirrors and lenses. The laws of geometrical optics are valid for infrared radiations as well. The energy and intensity of infrar ed radiation emitted by an object primarily depends on its temperature and can be calculated using the analytical tools such as Wein’s law, Plank’s law and Stefan Boltzmann law. When a body is heated, there is an increase in the temperature and emitted energy. The spectrum of infrared radiation emitted by a heated object contains a continuous band of wavelength over a specific range. The fundamental equations or radiation laws that link the absolute temperature of the emitting object, peak radiation, the intensity and wavelength are the Plank’s Law, the Stefan-Boltzmann Law and the Wein’s Displacement Law. The Plank’s law describes the spectral distribution of radiation intensity from a black body and is mathematically expressed as: [Wm-2sr-1?m-1] †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. (1) Where, W? = Blackbody spectral radiant emittance at wavelength ? (?m) c = 3x108 m/s is the velocity of light in vacuum h = 6.634 x10-3 4 Js is Plank’s constant k = 1.4 x10-23 J/K is Boltzmann’s constant T is absolute temperature of the blackbody Spectral radiant emittance of a blackbody at different temperatures is shown in Fig.1 [1]. Fig. 1: Spectral radiant emittance of a blackbody at different temperatures It can be seen in Fig. 1 that total energy radiated by a blackbody i.e. area under the spectral radiant emittance increases with increasing temperature of the blackbody. Further it can be seen that maxima of the spectral radiant emittance is shifting towards lower wavelength with increasing temperature of the blackbody. If one differentiates equation (1) with respect to ? and equates the differential to zero then one gets the relationship between the temperature of the blackbody and the wavelength corresponding to the maximum spectral radiance. This relationship is known as Wein’s law and is mathematically expressed as [2]: †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. (2) Where, ?max is the wavelength corresponding to the maximum spectral emittance T is absolute temperature of the blackbody This equation supports left ward shift of the spectral emittance peak with increasing temperature of the blackbody as in Fig. 1. Integrating equation (1) with respect to ? between the limits ? = 0 to ? for a given temperature T of a blackbody, one gets total radiant power emitted into a hemisphere from the blackbody. This relationship is known as Stefan’s-Boltzmann law and is mathematically expressed as: Total emittance [W/cm2] †¦

Suitable Network To Implement In Gaming Centre Computer Science Essay In this documentation, is going to propose a suitable network to implement in gaming centre. In order to select the right network, it is necessary to have understanding and knowledge on various types of network, to know the efficiency and reliability of the network, various types of game and requirement, network topology and architecture, ISP package selection, network component. Follow by types of game that going to provide to the customer, by providing several example of games requirement for making decision on different types of hardware and software to use in gaming centre. The game requirement is an important role that allows gaming centre to choose the suitable hardware for the computer in the gaming centre in order to achieve customer satisfaction. In order to allow customer to play online and LAN games with lowest connection latency, the selection of network topology and architecture is important. Due to the gaming centre is going to implement 30 gaming computer for the customer, the right topology and architecture allow customer to play online and LAN game smoothly. To play an online game with smooth connection, it is required to have good bandwidth of connection speed. Therefore, choosing the suitable package among other Internet Service Provider will be based on the connection speed. To build a complete and working network for the gaming centre, the major component of network cannot be missed out, which is computer, software, network interface device, and transmission media. Each of the components has different responsibility in order for a network to be complete. With the help of research on Internet, the model of device and type of application is recommended base on the specification of the hardware and software. However, these hardware and software may request to change by gaming centre after or before the implementation based on their justification. Assumption Below is some of the assumption of the gaming centre and network that going to implement:- The gaming centre will be providing high-end game to customer. Customers allow playing offline, online, and LAN games in the gaming centre. The gaming centre is capable of hosting tournament for different types of online and LAN games. The computer specification is sufficient enough for most of the high-end game. The connection bandwidth is capable to handle up to 35 computers in the gaming centre. The network topology, architecture and device recommended able to achieve the terms of scalability and flexibility for the gaming centre to expanding the business in future. Limitation There is some of limitation of the network that may require specialist or admin with relevant knowledge to solve the problem. These limitations may require paying extra attention by admin in order to minimize the lost that cause by it. The particular networks fail if the centralized device is encountering a problem. This may affect all computers that connected to the device. The network congestion problem occur when huge numbers of users trying to access the server to obtain the resource from the server. When the server is down or damage, it unable to handle and provide result of request by the customer such as starting a game. 1.0 Chapter 1 1.1 Introduction Wendell Odom (2004, pg.5) states that Network, a combination of hardware, software, and cabling, which together allow multiple computing devices to communicate with each other. In general, network basically means that numbers of computer being attached together in order to communicate and sharing information using cable. However, without proper configuration and supported software, communication and sharing information activities cant perform accordingly. Picture below shows the example of a network. Figure 1.1 Computer Network (http://www.home-network-help.com/wireless-router-as-access-point.html, n.d.) In order to create a successful network, it should consist of several parts, which is computer, software, network interface device, and transmission medium. Without any of the important part mention above, it will not call as a network. Computer is electronic devices that allow users to perform certain task easily compare to perform manually. Software is an application that helps computer to perform most of the task. Network interface device is referring to the device that uses to connect the computer with the internet, example modem, switch, router, and hub. Transmission medium is cable that connects the network interface device with the computer, as well as connects to the internet. People nowadays know that advantage of network is to share resources and information in shortest time and different geographical location. It helps to evaluate the travel time from one location to another location. Moreover, network also helps increased cost efficiency, this is refer to most of the software are published are costly and required certain amount of time to install. With the help of network, they can stored or install the software on a server so that it can be used by different workstation. In the gaming centre, it allow customer to access to the game play online or LAN games with players within or outside the gaming centre. 1.2 Type of Network 1.2.1 Wide Area Network (WAN) The gaming centre will be implementing the Wide Area Network, which is a combination of multiple Local Area Networks to allow customer to play online game as well as LAN game at the same time. Example of the WAN is Internet. It combines all the LAN that connected to the internet which allows users to communicate and sharing resource within the LAN or other LAN that connected to the Internet. Figure 1.2 WAN (http://wally.cs.iupui.edu/n241_06/files/webMag/index.html, n.d) The reason of having WAN for the gaming centre is due to the wide coverage of the network. The only resource needed for the gaming centre to implement is LAN that can access to the Internet, then it is automatically becomes part of the WAN. 2.0 Chapter 2 2.1 Computer Game Mark Stanfield and Thomas Connolly (2008, pg.25) states that The definition of computer games combines the more comprehensive concept of game with the use of computer. The game concept represents a structured or semi-structured activity with goal that players try to achieve and set of rules governing its operation. Base on the definition, game is referring to a well planned structure that consists of objective for anyone that plays it. However, player is required to understand and obey the rules and regulation of the specific in order to achieve the objective and gain achievement. Meanwhile, computer game is mean by the game can only be played using electronic devices which is computer. That the beginning of computer games, there is only offline game available and it required lesser disk space compare to computer games nowadays. Until today, there is plenty type of computer game on the market, such as online games, offline games, LAN games which is local area network games, and every type of computer games had been classified into different categories, for example RPG, FPS, RTS and many more. Offline games is referring to any games that can play by single player and unable to connect through the network and play with other players that playing the same game. An online game is referring to any type of game that can play using Internet and play or compete against other player. Lastly, LAN games is referring to any types of game that can played with other players within the certain area whereby users computer is connected to a same network. However, there are many games that can allow single player as well as multiplayer. Every game had its own requirement in order for player to play the games without any foreseen problem, the requirement divided into different categories, such as type operating system, processor, and type of graphic card, numbers GB of RAM, hard disk space, and also DirectX version. However, there is minimum requirement and recommended requirement which allow player to know that the specific game is suitable to play on their computer or not. Minimum requirement is to allow users to run and play the game in a normal performance and loading speed. As for recommended requirement, users able to run and play the game smoother in terms of performance and higher loading speed. As a LAN gaming centre, it is necessary to have various type of games provided to customer according to their favourite, and to satisfied the customer, there is certain level of knowing the games requirement and specification so that the centre able to choose the right hardware and software for the computer in the centre. By taking some example of the games requirement, it should be able to help in choosing the proper gadget for the computer. 2.2 Types of Game The game chosen to review the game requirement and use it as a reference for selecting the suitable hardware and software for the computer, Starcraft II, Warcraft 3, Counter-Strike: Source, Sudden Attack SEA, and Devil May Cry 4. The example of game chosen included online games, offline games, and LAN games. Online game example for this documentation is Sudden Attack SEA, which is first person shooting game and can only be played while connected with internet. Offline game is Devil May Cry 4 which is role playing game only for single player. Lastly LAN game, the example of game chosen is Starcraft 2 and Warcraft 3, a real time strategy game, and Counter-Strike: Source is a first person shooting game. These three games can be played with other player while connected to the network. However, it can be consider as offline, online game as well, due to these game are able to play with single player or connected to internet and play with or compete against other player. 2.3 Games Requirement Figure 2.1 Sudden attack SEA (online) (http://www.gx.com.sg/Blog/Blog.aspx?id=7ab57b16-fa13-4f2a-a937-0fb14368fec3, n.d) System Minimum Requirement Recommended Requirement CPU Intel Pentium 4 1.8GHz or above AMD Athlon XP2100 or above Intel Core 2 Duo or above AMD Athlon 64 X2 or above Memory 1GB or above 2GB or above (Win Vista/7) 2GB or above 4GB or above (Win Vista/7) Video Card 128MB or above 256MB or above Microsoft DirectX 9.0c compatible Graphic Card Operating System Windows 2000/XP/Vista/7 DirectX Microsoft DirectX 9.0c or above Hard Disk Space 3GB free space after game installation Table 2.1 Sudden Attack requirement (http://suddenattack.asiasoftsea.net/04-download/04-download_01_01.aspx, n.d) Figure 2.2 Devil May Cry 4 (offline) (http://cineclubecovilha.com/torrent/torrent/Devil-May-Cry-4-DVDDL-Full-PC-Gamedaa/2905/0.html, n.d) System Minimum Requirement Recommended Requirement CPU Intel Pentium 4 processor or better Intel Core 2 Duo processor or better Memory 512MB 1GB Video Card NVIDIA GeForce 6600 series or better NVIDIA GeForce 8600 series or better Operating System Windows XP service pack 2 Window Vista Hard Disk Space 8GB Drive DVD-ROM Drive Table 2.2 Devil May Cry 4 requirement (http://devilmaycry.org/243/devil-may-cry-4-pc-system-requirements.html, n.d) Figure 2.3 Starcraft II (LAN/Online/Offline) (http://www.keys4.me/starcraft-2-ii-wings-of-liberty-eu-cd-key-pc.html, n.d) For Windows OS System Minimum Requirement Recommended Requirement Operating System Window XP/Vista/7 (latest service pack) Window Vista/7 CPU 2.6GHz Pentium IV or equivalent AMD Athlon processor Dual Core 2.4GHz processor Graphic Card 128MB PCIe NVIDIA GeForce 6600 GT or ATI Radeon 9800 PRO or better 512MB NVIDIA GeForce 8800 GTX or ATI Radeon HD 3870 or better RAM 1GB (1.5GB for Window Vista/7) 2GB Hard Disk Space 12GB Others (hardware) Keyboard/mouse, Internet Connection Resolution Minimum 1024720 display resolution DirectX DirectX 9.0c Table 2.3 Starcraft II: Wings of Liberty requirement (for Windows) (http://us.blizzard.com/support/article.xml?articleId=26242locale=en_US, n.d) For Mac System Minimum Requirement Recommended Requirement Operating System Mac OS X 10.5.8, 10.6.2 or newer Mac OS X 10.6.5 or newer CPU Intel Processor Intel Core 2 Duo processor Graphic Card NVIDIA GeForce 8600 GT or ATI Radeon X1600 or better NVIDIA GeForce 9600M GT or ATI Radeon HD 4670 or better RAM 2GB 4GB Hard Disk Space 12GB Others (hardware) Keyboard/mouse, Internet Connection Resolution Minimum 1024720 display resolution Table 2.4 Starcraft II: Wings of Liberty requirement (for Mac) (http://us.blizzard.com/support/article.xml?articleId=26242locale=en_US, n.d) Figure 2.4 Counter-Strike: Source (LAN/Online/Offline) (http://www.moddb.com/games/counter-strike-source, n.d) For Windows System Minimum Requirement Recommended Requirement CPU 1.7GHz processor Pentium 4 processor (3.0GHz or better) RAM 512MB 1GB Graphic Card DirectX 8.1 level graphic card (Requires support for SSE) DirectX 9 level graphic card Operating System Windows 7 (32/64-bit) / Vista / XP DirectX DirectX 8.1 or above DirectX 9 or above Table 2.5 Counter-Strike: Source requirement (for Windows) (http://store.steampowered.com/app/240, n.d) For Mac System Minimum Requirement Operating System OS X version Leopard 10.5.8 Snow Leopard 10.6.3 RAM 1GB Graphic Card NVIDIA GeForce 8 or higher ATI X1600 or higher Intel HD 3000 Others (hardware) Mouse, Keyboard, Internet Connection Table 2.6 Counter-Strike: Source requirement (for Mac) (http://store.steampowered.com/app/240, n.d) Based on the example of game requirement shown above, it clearly shows that different game have its own minimum and recommended requirement in order to play the game smoothly. Games requirement are usually based on previous version of graphic card or processor that already in the market to allow more player to play the games with their current computer. It also shows that different year of published the game may affected the requirement directly. With the example given for different games requirement, it helps the gaming centre to choose the right hardware for the gaming computer. 3.0 Chapter 3 3.1 Topology The topology choose to implement in the gaming centre is star topology. Star topology is one of the most common topology that used in current days. In star topology, every device is connected to a centralized device such as switch, router, or hub via Ethernet cable. This topology arrangement creates a point-to-point network connection between two devices and overall gives the appearance of a star. The reason of implementing the star topology in the gaming centre is the level of flexibility and expandability is high. Multiple star can combine as a hierarchical star and connectivity of the network on one particular computer will not affected other computer that connected to the same network unless the whole centralized device or main cable connected with the modem or router is damaged. Figure 3.1 Star Topology (http://tjliu.myweb.hinet.net/COA_CH_12.htm, n.d) 3.2 Architecture The architecture that suggested implementing in the gaming centre would be client-server architecture. Client-server architecture is referring multiple user computer connect and interact with one or multiple server that connected within same network. This architecture allows multiple users to submit request at the same time, and the server able to react to the request and provide result to user requested accordingly. Server are usually powerful machine due to the workload is heavy and need to be complete within short period of time. The reason of implementing client-server architecture to the gaming centre is due to the resource will be kept in the server that connected to the same network with the users computer. If the gaming centre decides to expand and add more computers to the network, it would be very easy to configure and it wont affect other clients connection with the server. Figure 3.2 Client-server (http://www.javaworld.com/javaworld/jw-10-2001/jw-1019-jxta.html, n.d) 3.3 Internet Service Provider ISP is the companies that provide Internet service to the people by subscribe various packages that give various amount of Mbps and services to the customer. Some ISP also provides modem/router for subscribing their package. The ISP that suggested is TM. Currently TM is promoting high speed broadband called Unifi, these package allow customer to enjoy the speed from minimum 5Mbps up to 20Mbps. For the gaming centre, the BIZ 10 package is sufficient enough for gaming. Below shows some of the key features of the BIZ 10 package:- Download and upload up to 10Mbps 1 fixed IP Unlimited usage 2 online guard plus 2 ishield plus 3.4 Component of Network In earlier part of documentation, it states that a complete network consists of 4 major components. The components are, computer, software, network interface device, and transmission medium. If lacking either one of the components, a network will not complete. 3.4.1 Computer Computers, a component that responsible on dealing with the user and connection, to setup, configure and maintain the network. Gaming centres main objective is to provide good service in terms of game playing satisfaction for customer to gain profit. In customer view, they usually hope to play game without any connection latency problem, or display lagging problem during the game. And also external hardware such as keyboard, mouse, and headphone also must be in good quality to satisfy the customer. In order to achieve the objective, choosing the right hardware for the computer would be important. Due to the computer hardware is updating model and performance frequently, there is impossible for a gaming centre to get a set of latest hardware for computer in the gaming centre, because it is costly. In this case, the computer that installed in the gaming centre would be a customize computer, which means the CPU itself is installed based on buyers need. Therefore, the computer specificat ion for the gaming centre is shown on table below. System Component Device model Operating system Windows 7 Ultimate 32-bit CPU Intel Core i5 650 @ 3.20GHz RAM 4GB Graphic Card ATI Radeon HD 5670 DirectX DirectX 11 Table 3.1 Computer Specification In order for gaming centre to keep the important data and information such as finance report or employees profile. It is highly recommended to implement server in the gaming centre. Server also allows gaming centre to store the games that going to play by the customer. Customer able to play any games that already installed in the server of the gaming centre, by choosing and click on the games shortcut inside the computer, customer are able to play the game freely. The model of server recommended to implement in gaming centre is Dell PowerEdge R515 2U Rack Server. It is suitable for storing database, application, email and others file. This model of server consists up to 25TB of internal storage space. And is easy to manage with the help of dell management console, and interactive LCD screen and other features to allow administrator to monitor and maintain the server frequently.

For the server, it is recommended to install Windows small business server 2008. This particular operating system support internet connectivity, internal Web sites, remote access, file and printer sharing, backup and restore to secure all the resource that installed in the server. For securing the computer in the gaming centre from virus attack and hacking, the antivirus also required to install. The KasperSky anti-virus 2011 is the latest and suitable to protect the computer in gaming centre. In order to maintain and configure the network easily, the Cisco routers are integrated with Cisco IOS which is an all-in-one network operating system that allow user maintain the network using Cisco IOS Command Line Interface (CLI). With the help of Cisco IOS, administrators can configure, monitor and troubleshoot the system easily. Last but not least, all the games software or client need to installed into the server to allow customer to access. The reason of installing all games client is to save time on install and maintain. When a games encounter a problem, admin can solve it on the server side compare to install in each pc, admin have to solve the same problem over and over again when problem encounter. 3.3.3 Transmission Media The transmission media used for the gaming centre is Unshielded Twisted Pair (UTP) and wireless. UTP is the most commonly used media for connecting from device to device in various type of network. It consists of eight individual copper wires and each of the wires are covered by an insulating material and twisted around each other. Upon searching for information regarding UTP (CICSO, 2004) has shown various category of UTP cable. Category 1 Used for telephone communications. Not suitable for transmitting data. Category 2 Capable of transmitting data at speeds up to 4 megabits per second (Mbps). Category 3 Used in 10BASE-T networks. Can transmit data at speeds up to 10 Mbps. Category 4 Used in Token Ring networks. Can transmit data at speeds up to 16 Mbps. Category 5 Can transmit data at speeds up to 100 Mbps. Category 5e Used in networks running at speeds up to 1000 Mbps (1 gigabit per second [Gbps]). Category 6 Typically, Category 6 cable consists of four pairs of 24 American Wire Gauge (AWG) copper wires. Currently the fastest standard for UTP. The reason of having UTP to be implement in the gaming centre is due to the cost for the cable is cheap compare to other type of cables and is easier to install as well. It also can support multiple signals travelling through the same cable. Figure 3.3 Unshielded Twisted Pair cable (http://www.tech-faq.com/utp.html, n.d) 3.4.4 Network Interface Device For network interface device, is the component that act as the middle man in terms of business, it is connected with the users computer, and also Internet to handle data transferring, such as modem, router, switch, hub, and bridges. The device that implement in the gaming centre is modem, router, and switches. Each three device have different usage, modem, allow users to gain access to the internet which usually provided by the Internet Service Provider company upon subscribe the package. Router, to allow more than two users to connected and access to the internet, it also allow users to form a LAN. Switches, allow multiple users to communicate and sharing resource within the network.

Toyotas Secret :: essays research papers

If you enter the lobby of Toyota’s headquarters in Japan, you will see two small portraits and one big one hanging there. The two small ones show the founder and the current chairman of the company. The large portrait shows an American. It is Dr. Edward Deming. Who is Edward Deming you might ask? And indeed who is he? But it’s a long story and one cannot explain who Edward Demings is without involving characters like the Japanese, the Americans and the Toyota Company. So here goes†¦ Long Ago and Far Away†¦ World War II had barely ended, the Japanese were left with a devastated country, ruins that were previously houses and a battered economy. But there was something left that helped them overcome all this destruction. They did not sit and lament their fates but began thinking†¦where do we go from here and to get there what do we need to do? Factories began production again firstly to supply all the basic necessities and after around 15 years when everyone had the basic goods they needed, they turned their energies towards overcoming the surplus of imports. Japan needed to offer something more in their goods if they had to succeed on foreign shores.... The Japanese car manufacturers namely Toyota wanted to start operations in America. That was all very well. But how could they make the Americans buy their cars rather than local ones. Enter Dr. Edward Demings and hey presto! They had the secret recipe!   Ã‚  Ã‚  Ã‚  Ã‚  The man who according to his biographer Rafeel Agumayo(1) is the American who taught Japan what quality management is. Dr. Edwards Deming was a physicist specialized in the field of statistics and worked in United States Bureau of Census. His greatest contribution on the evaluation of statistical methods for ensuring the quality of census assessment established him as a leader in the field of Total Quality Management. In fact he is considered as the "Guru" of Total Quality Management. Deming also enunciated 14 principles for quality management which include innovation, the philosophy of quality to be inculcated in all individuals, appropriate and complete supervision, absence of fear and openness, ensuring quality from design through to maintenance, work standards in production, training of every worker in statistical methods, retraining people to new skills and so on. The world saw Toyota take over America by storm, they offered better, faster, more comfortable and more efficient cars and Americans came to buy cars from them in droves.

Crisis Management 1: The Day After Tomorrow

There is probably no better movie in the world to look at crisis management and Hollywood’s lack of understanding than â€Å"The Day After Tomorrow†. This movie deals with a major catastrophic event worldwide and shows viewers the alleged reaction of the American government. Although it provides interesting drama for the movie, the way the American government reacts to the crisis is not only a poor example of crisis management, but also paints an unrealistic picture of the efficiency of the government and emergency responders. From the beginning, the movie is a bit preachy about the environment and the American government’s unwillingness to listen to the doomsayers about the coming crisis. No one from the vice president down wants to hear what the government employed climatologist has to say about the weather. The first problem with this is that the climatologist is even trying to report to the vice president. It is possible that in an extreme crisis situation, the chain of command might be broken to get more information quickly to decision-makers, but the main character does so before the crisis even hits the United States. If he had followed the chain of command, it seems more likely that crisis response teams could have begun developing scenarios for the crisis he was envisioning. Evaluating the crisis response in this movie in many ways comes down to evaluating the response to several major crises leading up to the huge global cooling event.   The first event that affects the United States is a huge weather system, so-called super storms which ground air traffic and begin causing flooding in Lower Manhattan.   At approximately the same time, we see a series of huge tornadoes devastate Los Angeles and then we see the President declare a national state of emergency. However, not a single one of these crises were handled in accordance with crisis management theory or crisis management reality as it exists today. First we will deal with the super storm and the subsequent plane crashes. The first evidence that we as viewer have of the increasing storm activity is on the flight of Jake Gyllenhaal’s character from Washington D.C. to New York for a scholar bowl competition. Sam, Gyllenhaal’s character, is supposed to be terrified of flying anyway, so when the plane hits turbulence the effect is supposed to be suspenseful. But from an emergency management point of view, it is evidence that the Federal Aviation Administration would have grounded flights long before the lightning got so bad that it was knocking planes out of the air. The movie claims several major plane crashes occur before the FAA can get planes out of the sky. This is just hogwash. After September 11, 2001, the FAA has procedures in place to scramble to get planes on the ground. Tiny airports dotting the countryside are equipped for emergency landings and after the turbulence on one flight was bad enough to activate oxygen masks, the FAA would have immediately grounded flights flying through that storm. The second major problem that the movie has with crisis management comes in the form of the flooding in Lower Manhattan. When the problem is simply a backed up sewer at a prep school, it is possible that the response would be to move the students to alternate locations in the city until the morning. However, these were high school children. There is no way that the school system would have allowed them to begin randomly moving around the city the next morning when the flooding had extended to the streets and made some roads and rail lines impassable. In addition, major flooding on an island like New York is a major crisis event. The movie depicted the beginning of the horror in New York City as just another rain storm and showed no evidence of a crisis response from city officials. Even if the sudden cold snap had been unpredictable, the rain forecast wasn’t and city officials and emergency personnel would have been preparing in one way or another before the freeze hit. This utter lack of regard for reality and crisis management strikes home again later in the movie when Sam and others have taken refuge in the library. For unknown reasons, the lone police officer in the bunch decides that it is better to encourage people to walk out of the city rather than stay in the relatively warm and dry library where they have shelter and some food. While not all police officers are trained to handle a serious crisis, the idea that this one encouraged people to give up shelter and food to being an unknown trek is completely against any crisis management theory taught in the world. He had no reason to believe that people would not be safe in the library and should have, would have kept them there. The response in Los Angeles to the tornadoes was also just ridiculous. The movie shows the country watching in horror as LA is destroyed, but no once do we hear the Federal Emergency Management Personnel begin mobilizing or calling their local counterparts or in any way reacting to the scene.   Given the nature of the disaster, FEMA officials should have been on the phone before the winds stopped mobilizing search and rescue teams immediately to secure the city and recovery teams should have been getting their alerts as well. Instead, the movie makes it appear that California was basically ignored as it was blown away. Finally, the real tragedy of the crisis approach in the movie is that the movie makers failed to realize that this type of national event would almost immediately result in martial law. Doctors would not be allowed to wait around at hospitals to see if their patients were evacuated and private ambulance companies would not be the ones emptying the hospitals of the transportable patients as the country was evacuated. And, the president would not be allowed to refuse to move out of his office. He would be taken into some kind of mobile command center, against his will if necessary, for the preservation of the country. Like any good â€Å"Die Hard† movie, â€Å"Die Hard with a Vengeance† involves bad guys and hostages. What makes this a classic crisis movie is the portion of the movie dealing with the hostages in a public elementary school in New York City. The basic plot of the movie is that Bruce Willis and Samuel L. Jackson have to stop the bag guys and get the code to defuse the bomb in the school so that the hostages can get away.   The problem is that the bad guys have claimed that if they see anything indicating that the school is being evacuated they will use a remote detonator and set off the bomb as the children try to evacuate. This movie does some things right as far as crisis management theory goes. School personnel, including teachers, are enlisted to help emergency personnel devise a plan to evacuate the building and the bomb squad is brought in to attempt to find and defuse the bomb.   Then, it wanders away from reality and never finds its way back. Detective John McClain (Bruce Willis) runs into a father with two children at the school. Zeus Carter (Samuel L. Jackson) refuses to take no for an answer and insists on helping McClain find the bad guys. Wrong! One of the most important theories of crisis management is to minimize the risk.   The police would never let an untrained civilian get involved in the operation. If Mr. Carter insisted, he would be arrested and held until the crisis was over. The next step would be to remove the children from the location. Even though the bombers had threatened to detonate the bomb as soon as they saw any attempt to rescue the children, the first priority would have been to evacuate the children.   A large portion of crisis theory is risk management and despite the fact that we were dealing with children and the potential loss of life, those in charge of crisis management would have decided that it was better to attempt to get the children out of the building rather than leave them as sitting ducks for the bad guys to blow up at will.   The goal of the crisis management team would have been secure the building in any way possible and to prevent as much loss of life as possible. Though they would understand the potential for second guessing if something went wrong, they would have also seen the potential for the situation to simply get worse if the children were not immediately removed from the building.   While the idea of having the children sprint away from the building as fast as possible seems sound, the reality is that it would not have been tried as the potential for injury there would be great as well. Real crisis management teams would have figured out when the bomb was and gotten the children to the exits farthest from it and then attempted to put in some sort of blast shielding to minimize the danger while removing the children from the situation. Even more disturbing is the fact that the movie depicts the evacuation process as chaotic enough to allow two children to slip away from their teachers and law enforcement personnel to hide out in the school. In a real emergency, teachers would have checked and double-checked to make sure that every student was accounted for and emergency personnel would have been patrolling the building behind the evacuees to make certain that no one stayed behind. Finally, there was only a limited effort to control the news media. In a major crisis event of this type, cellular communication with the building would have been terminated in an effort to prevent word of the hostage crisis from reaching the media and in the event that the media were made aware of the crisis, strict controls would have been used to keep them quiet about the crisis, including blackmail. It is not unusual for crisis personnel to make it clear to the media in the midst of a crisis that cooperation during the crisis will lead to better access to stories once the crisis is over. And, the news media makes decisions daily when it weighs the public’s need to know against security. If the reporters were informed of the delicate nature of the situation and the potential for the loss of human life, most would have willingly gone along with a blackout of the event until after the children were safe. The problem is that real crisis management does not necessarily make for good drama. Though the conflicts in decision-making procedures exist, they are not open discussions that anyone can participate in. In a real emergency, the crisis management is left to the professionals. It’s too bad movies can’t seem to understand that. The beauty of the crisis situation in â€Å"Dawn of the Dead† is that the crisis appears quickly, but not instantly and it develops mostly over night. This crisis is also insidious in that people become infected and may not demonstrate their symptoms for several hours or even a day later. Worse yet, for crisis management teams, it is the worst type of crisis imaginable—the nature of the threat is unknown but rapidly spreading and the disbelief that we have trained into ourselves and our children works to prevent rapid response to the crisis. The plague causing the zombies in â€Å"Dawn of the Dead† has the ability to take hold and gain strength because the first few times that medical personnel run into it, they disbelieve what they are seeing. Though it is important for emergency personnel to be skeptical, they c=should be willing to act based on observable facts even when the facts make no sense. That is the major failing of the emergency response in this movie. Otherwise, the writers largely got it right. When it became clear that a major epidemic was facing the city, officials would first have warned people to remain in their homes and then, barring that would have set up emergency shelters. One of the good things about the use of emergency shelters in the movie is that they used traditional shelters like churches and a military base, an option that definitely would be considered in the event of a widespread event. The fact that before the emergency broadcasts end, they have contacted officials with the Centers for Disease Control and that the CDC is in charge on the event makes a great deal of sense. The only thing lacking would have been a stronger military presence on the streets once the state of emergency had been declared, but at least the movie attempts to explain this too when it mentions later on that the Army base has been overrun. Even more impressive than the outside response to the crisis, is the crisis management implementation that develops within the group of survivors. Though there is some initial posturing between the thief and the police officer, everyone quickly falls into roles appropriate to the situation and begins to work together to overcome their immediate needs: shelter that is safe from the threat. The opening scenes of the movie show people doing what is necessary to survive, even when it contradicts what it their normal behavior pattern, a classic observation of crisis theory. People will do what they need to do in order to survive. This is true in the killing of the zombies and even the decisions to flee their homes. Once they arrive at the mall, after the mall is secured and they have successfully risen up against the mall security guards, the group begins to settle into the realities of crisis management: they determine if they can meet their basic needs and then if there is an escape their condition. They put notes on the building roof to indicate the presence of survivors and they take up whatever pursuits help them get through the monotony of existence while the threat continues, including Steve’s incessant need for sex and the â€Å"games† of kill the zombie that they play from the mall rooftop. Finally, the group reaches the point where it must investigate the threat and determine how to handle it. The movie does a good job of showing the learning process and the impact of all the stresses on the psyche of the people involved.   The group determines to leave the mall when it becomes clear that they cannot live their indefinitely and then they begin a very crisis management approach to leaving, setting up supplies ad making their exit as defensible as possible.   The only failure in their crisis management theory is the lack of available information with regard to other safe havens. It proves to be their undoing. However, unlike the other movies I have reviewed, this one seemed to understand that theory. 1) Control or contain the threat 2) Seek Shelter 3)Seek other basic necessities. I think many other disaster movies would be more enjoyable if they could follow his pattern and stick to reality.

Layers of the Earth Essay

The Crust is the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust. It is made roughly from silicon, oxygen, iron, and magnesium. The layer is composed almost entirely of magma – molten rock inside the earth. The mantle is about 2,900km thick. The mantle gets warmer with depth; the top of the mantle is about 870Â ° C, headed for the bottom of the mantle, the temperature is about 2,200-3,700Â ° C. Outer Core is the third layer. This level is basically liquid. Most of this layer is made from liquid nickel and iron. Outer Core is about 2,200km thick. The temperature of the Outer Core is 4000-5000Â °C. Inner Core is the fourth layer of the Earth. The thickness of the Inner Core is 1,250km and mainly consists of iron, nickel and some lighter elements (probably sulphur, carbon, oxygen, silicon and potassium. The temperature in the inner core is about 5000-6000Â °C, it is the hottest layer of the Earth. Because of the high pressure, the core is solid. If a person were to travel that deep, they would burn up with in the Mantle before they ever came near the core. Even with a ship that could withstand the high temperature, it would be crushed by the great pressure.
