Comparison Minority Report and 1984 - 1352 Words
Is it inhumane to arrest and convict a person of terrible crimes, even if it is not yet committed, if it is certain that it will be? Utopia is an imaginary place in which everything is perfect; in comparison, dystopia is an imaginary state in which the condition of life is extremely bad as from deprivation, oppression, or terror. George Orwellââ¬â¢s 1984 (1949), is a novel based on life in a dystopian setting, with a totalitarian government centered on war and hatred. Steven Spielbergââ¬â¢s Minority Report (2002) is a film in a futuristic setting with a system which predicts future murders so that citizens live a homicide-free utopian life.

Case study: South Africa South Africa is an upper-middle income country with a population of 52 million people and a GDP of 312.80 billion US dollars (ââ¬Å"Statistics South Africa | The South Africa I Know, The Home I Understandâ⬠, n.d.). The country has the second largest economy in Africa; it plays a prominent role in sub-Saharan Africa and in the continent as a whole. South Africa was hugely shaped by the apartheid legacy, a system of racial segregation that began during the colonial rule and was officially enforced by the National Party after the elections of 1948. Apartheid regime ended in 1994 and the newly elected government led by the African National Congress (ANC) had to deal with enormous challenges in terms of poverty and huge inequalities.

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction) (Rouse, 2005). Basically Inertia is a word we use when we talk about matter and movement (Unknown Author, Unknown Date). This idea goes all the way back to Sir Isaac Newton, a great physicist. We will write a custom essay sample on MOving About or any similar topic only for you Order Now In Newtonââ¬â¢s first law of motion it is stated that: 1 . An object at rests tends to stay in rest 2. An object in motion tends to stay in motion A great example of inertia would be if a car is driven directly into a brick wall, the car would stop because of the external force which is exerted upon by the wall. The driver requires a force to stop his body from moving forward, this can be prevented by a settable, or otherwise inertia will cause his body to keep moving forward until his body is acted upon by the same force. Newtonââ¬â¢s First Law: Newtonââ¬â¢s First Law of Motion states that ââ¬Å"Every object continues in its state of rest or uniform motion unless made to change by a non-zero net force. â⬠This law says if an object is accelerating, that is it experiencing a change on velocity, and then an unbalanced (or resultant or net) force must be acting upon it (Warren, N, 2004). From his law we can conclude that forces cause changes in motion (that is, accelerations)- they do not cause motion (Warren, N, 2004). . Newtonââ¬â¢s First Law, Image Courtesy by: Revision World Newtonââ¬â¢s first law is not apparent in real world situations because there are usually too many external forces acting upon objects on the Earthââ¬â¢s surface. Common experience does not always seem to be in agreement with this law (Warren, N, 2004). A driver of a car on a level road for example, still needs to press the accelerator to move at a constant speed (Warren, N, 2004). Why does the car not accelerate? The season, of course, is that friction exists between the car and the road (Warren, N, 2004). Hence the forces in this case are balanced and so the law is valid (Warren, N, 2004). To accelerate the car, we need to apply an unbalanced force, that is, press the accelerator more (Warren, N, 2004). Low Speed zone, Road Rules and Safety devices: In recent years many local councils have introduced lower speed limits and placed speed humps in streets to reduce the speed of cars (Warren, N, 2004). Evidence shows, and physics dictates, that slower moving cars cause less damage to occupants if a crash results (Warren, N, 2004). The speed humps makes it difficult for drivers to speed since they would damage their cars if they hit humps too fast (Warren, N, 2004). Low Speed zones are in place because, the lower your velocity, the less momentum you have and the quicker you can stop (Unknown Author, 2007). Low speed zones keep the risk of major damage to a minimum by decreasing the momentum of cars (Indri, U, 2011). Momentum increases with both velocity and mass, as shown in the equation (Indri, U, 2011). It is important to keep momentum low because in the equation, as the momentum (P) increases, so does the impact force (F) (Indri, U, 2011). Therefore lower speed zones also allow for a shorter stopping distance, reducing speed decreases the chance of a collision to take place, by decreasing the stopping distance and lowering momentum (Indri, U, 2011). Modern cars are built with many safety devices including: 1 . Seat Belts 2. Airbags 3. Crumple Zones Each of these devices works by effectively increasing the over which passengers are brought to rest in the event of collision (Warren, N, 2004). Air Bags and Crumple Zones both increase the stopping distance of a vehicle. Relating back to Impulse = Force X Distance, If the distance is increased, the force is lower, this reduces the ores put on the vehicle, and the occupants inside it (Unknown Author, 2007). Seat Belts: (Explain in terms of inertia) In 1948 Tucker cars became the first car company to include seat belts, prior to which even minor motor vehicle accidents could cause serious injury (Marshal and Gibson lawyers, 2012). In 1968, the United States was the first country in the world to make it a legal requirement that all new cars have seat belts (Marshal and Gibson lawyers, 2012). A seat belt is a safety harness designed to secure the occupant of a vehicle against harmful movement that may result from a collision (Indri, U, 2011). As part of an overall occupant restraint system, seat belts are intended to reduce injuries by stopping the wearer from hitting hard interior elements of the vehicle or other passengers and by preventing the passenger from being thrown from the vehicle (Indri, U, 2011). Most seat belts are equipped with locking mechanisms (or inertia reels) that tighten the belt when pulled fast (e. G. Y the quick force of a passengerââ¬â¢s body during a crash) but do not tighten when pulled slowly (Indri, U, 2011). This is implemented with a centrifugal clutch, which engages as the reel spins quickly (Indri, U, 2011). Alternatively, this function may be secured by a weighted pendulum or ball bearing: when these are deflected by deceleration or roll-over they lock into pawls on the reel (Indri, U, 2011). There are three types of inertia reel seat belts: 1. NIL-(No Locking Retractor) 2. LEER V-(Emergency Locking Retractor-vehicle sensitive) 3. LEER M-(Emergency Locking Retractor-vehicle and Webbing sensitive) Air bags: Hitcher, a retired industrial engineering technician, received a patent in 1953 for what he called a ââ¬Å"safety cushion assembly for automotive vehicles (McCormick, L, 2006). â⬠His U. S. Patent No. As the first prototype for todayââ¬â¢s modern airbags (McCormick, L, 2006). Hitcher designed the system to reduce injuries during emergency braking and frontal collisions, according to a story in American Heritage about his invention (McCormick, L, 2006). In that story, Hitcher recalled the inspiration for his invention: ââ¬Å"In the spring of ââ¬â¢52, my wife, my seven-year-old daughter, Joan, and I were out for a Sunday drive in our 1948 Chrysler Windsor (McCormick, L, 2006). About three miles outside Newport, we were watching for deer bounding across the road (McCormick, L, 2006). Suddenly, there was a large rock in our path, Just past the crest of a hill (McCormick, L, 2006). I remember hitting the brakes and veering the car to the right (McCormick, L, 2006). We went into the ditch but avoided hitting both a tree and a wooden fence (McCormick, L, 2006). As I applied the brakes, both my wife and I threw our hands up to keep our daughter from hitting the dashboard during the ride home, I couldnââ¬â¢t stop thinking about the accident (McCormick, L, 2006). I asked myself: Why couldnââ¬â¢t some object come out to stop you from striking the inside of the car? (McCormick, L, 2006)â⬠When he returned home, Hitcher started s ketching designs for his ââ¬Å"safety cushion. McCormick, L, 2006)â⬠The primary purpose of the airbag is to slow the passengerââ¬â¢s speed to zero with little or no damage (Indri, U, 2011). The constraints that it has to work within are huge (Indri, U, 2011). The airbag has the space between the passenger and the steering wheel or dashboard and a fraction of a second to work with (Indri, U, 2011). Even that tiny amount of space and time is valuable, however, if the system can slow the passenger evenly rather than forcing an abrupt halt to his or her motion (Indri, U, 2011). There are three parts to an airbag that help to accomplish this feat: 1 . Air Bag: The bag itself is made of a thin, nylon fabric, which is folded into the steering wheel or dashboard or, more recently, the seat or door. . Crash Sensors: These small pieces of electronics are designed to tell when the vehicle has been damaged in an accident (Cars Direct, 2013). They respond to several different sets of stimuli, including sudden stopping, increased pressure as pieces of the car are moved due to the force of the collision, and more (Cars Direct, 2013). A mechanical switch is flipped when there is a mass shift that closes an electrical contact, telling the sensors that a c rash has occurred (Indri, U, 2011). The sensors receive information from an accelerometer built into a microchip (Indri, U, 2011). According to an engineering study and airbag can be deploy in 55 milliseconds. 3. Inflators: Once the control unit determines there is an accident, it sends a signal to the inflator system (Cars Direct, 2013). The inflator sets off a chemical charge, producing an explosion of nitrogen gas, filling up the airbag (Cars Direct, 2013). As the airbag fills up, it bursts through the paneling that contains it and enters into the space of the car in order to protect you (Cars Direct, 2013). Thus the use of the airbag decreases the overall force that is applied on the passenger resulting in less serious injuries and thus saves lives (Indri, U, 2011). . Impact Triggers Air Bag Inflation, Image Courtesy: Stephen Ramp Crumple Zones: The concept of the crumple zone safety feature was first used by the Mercedes-Benz engineer Bella Barrens on the 1959 model Mercedes-Benz ââ¬Å"Fantailâ⬠(Rive, M, Unknown Year). This innovation was first patented by Mercedes-Benz in the early sass (Rive, M, Unknown Year). The patent was then granted as patent number 854157, minion (Rive, M, Unknown Year). A crumple zone is an area of the vehicle that is designed to change shape on impact with another object at high speed (Graininess, E, 2008). This is in order to redistribute the force exerted on the vehicle so that the driver remains relatively unharmed (Graininess, E, 2008). This is achieved by crafting the front and rear of the vehicle from a material that is designed to bend or collapse into itself upon impact (Graininess, E, 2008). Often, engineers will have to compromise between using a material that offers too little resistance to force and too great a resistance to force (Graininess, E, 2008). The best way to reduce the initial force in a crash with a given amount of mass and speed is to slow down the deceleration (Indri, U, 2011). Youââ¬â¢ve seen this effect for yourself if youââ¬â¢ve had to slam on your brakes for any reason (Indri, U, 2011). The forces you experience in an emergency stop are much greater than when you gradually slow down for a stoplight (Indri, U, 2011). In a collision, slowing down the deceleration by even a few tenths off second can create a drastic reduction in the force involved (Indri, U, 2011). . The crumple zones and the passenger section of a car, Image Courtesy By: Mechanics Momentum In the equation Force = mass X acceleration (F=M x A), cutting the deceleration in half also cuts the force in half therefore, changing the deceleration time from . 2 seconds to . 8 seconds will result in a 75 percent reduction in total force (Graininess, E, 2008). Crumple zones accomplish this by creating a buffer zone around the perimeter of the car (Graininess, E, 2008). Certain parts of a car are inherently rigid and resistant to deforming, such as the passenger compartment and the engine (Graininess, E, 2008). If those rigid parts hit something, they will decelerate very quickly, resulting in a lot of force (Graininess, E, 2008). Surrounding those parts with crumple zones allows the less rigid materials to take the initial impact (Graininess, E, 2008). The car begins decelerating as soon as the crumple zone starts crumpling, extending the deceleration over a few extra tenths of a second (Graininess, E, 2008). The fundamental idea is that it takes force to damage them. Crumple zones spend as much force as possible so that other parts of the car as well as the occupants donââ¬â¢t suffer the effects (Indri, U, 2011). Effectiveness of Safety Devices: Seat Belts: Wearing a seat belt is one of easiest ways of protecting drivers and passengers when traveling in a vehicle (Western Australia Government, 2014). Seat belts protect vehicle occupants by decreasing the time it takes them to come to a stop in a crash, spreads the impact force over a greater area of the body, minimizes contact with the interior of the vehicle and helps stop them from being ejected from the vehicle (Western Australia Government, 2014). Failure to wear a seat belt contributes to more fatalities than any other single traffic safety-related behavior (Indri, U, 2011). % of people killed in accidents are not wearing seat belts (Indri, U, 2011). Wearing a seat belt use is still the single most effective thing we can do to protect ourselves in case of an accident (Indri, U, 2011). . Seat Belts, Image Courtesy By: Tableaus Seat belts are the most effective safety devices in vehicles today, estimated to save 9,500 lives each year (Indr i, U, 2011). Yet only 68 percent of the motor vehicle occupants are buckled. In 1996, more than 60 percent of the occupants killed in fatal crashes were unrestrained (Indri, U, 2011). . Fatalities where NV Occupant was Unrestrained, Image Courtesy By: Australian Government As you can see from the graph above after 2007 number of fatalities who were unrestrained have decreased over the year. This is because more effective laws came in and police patrol on roads also increased over the years. Our better understanding of safety of devices such as seat belts has also played a major part. Statistically, individuals who are in accidents that have manufacturer- installed airbags and who properly wear their seat belts have a better chance of making it out of a serious accident without serious injuries (Safer, 2006). Crumple Zones: In a typical crash scenario, the crumple zone effectively redistributes the force of impact on the vehicle, leaving the ââ¬Ësafety cellââ¬â¢ intact whilst the front or rear of the vehicle is completely deformed (Car Safety Systems and Unknown Date). This means that the crumple zone is working correctly (Car Safety Systems and Unknown Date). However, crumple zones are designed to work in tandem with the additional safety features of a modern vehicle, such as the airbags, settable and collapsible steering column (Car Safety Systems and Unknown Date). Crumple Zones, Image Courtesy sys; ââ¬Ë(21968 Crumple zones allow the front of the vehicle to crush like an accordion, absorbing some of the impact of the collision and giving some off in the form of heat and sound (K-12 School Websites, 2006). The front of the vehicle effectively acts as a cushion that slows the time it takes for the vehicle to come to a complete stop, applying less force on passengers, which could help save their lives (K-12 School Web Pages, 2006). Newtonââ¬â¢s second law of motion, force = mass x acceleration, conveys that as the time it takes for an automobile to come to rest or change direction is increased, the force experienced by the automobile (and its occupants) is decreased (Erickson, Christopher, 2006). Conversely too, if the time to stop is shorter, the force experienced is greater (Erickson, Christopher, 2006). Crumple zones add time to the crash by absorbing energy (Erickson, Christopher, 2006). Air Bags: In Australia during 1997, the then Federal Office of Road Safety collaborated with UNCAP on a consumer information program comparing the injury outcome of a series of vehicle models with and without airbags (RACE, Unknown Date). The first release covered larger passenger cars that are popular with families and fleet buyers (RACE, Unknown Date). The test results showed that an airbag halves the chance of suffering a serious head injury (RACE, Unknown Date). A second series looked at the small car group which are very popular with private and first-time new car buyers (RACE, Unknown Date). Again the test results showed that an airbag at least halved the chance of suffering a serious head injury (RACE, Unknown Date). . Airbags, Image Courtesy By: Sally Dominique A recent US study has shown side airbags also to be highly effective in reducing the risk of serious injury or death, particularly those that include head protection. Previous research has shown that the installation of air bags in vehicles significantly reduces crash related deaths, but these analyses have used statistical techniques which have not been capable of controlling for other major determinants of crash survival (Barry, S, Gimping, S, Oââ¬â¢Neill, T, 1999). Loose Objects in Cars: Every year, loose objects inside cars during crashes cause hundreds of serious injuries and even deaths (Abrahamââ¬â¢, D, Wesleyan, M, Lamar, A, 2011). Recent studies have shown that many drivers are increasing the risk of injury or death in automobile accidents by leaving items unsecured (Grubber, D, 2012). The potential angers of loose objects in vehicles are strongly associated with Newtonââ¬â¢s First Law of Motion, inertia (Cantina, 2005). For example, say a car is traveling along a straight road (Cantina, 2005). Loose objects in the auto are ââ¬Å"acted uponâ⬠by the body, seats, or some other part of the vehicle (whatever is touching a loose object), whenever the car accelerates (Cantina, 2005). Letââ¬â¢s say we stop the car instantaneously and turn the car so it faces left (Cantina, 2005). What happens to all the loose objects inside the car? They are still going to obey the First Law of Motion, and try to continue going down the straight road (Cantina, 2005). However, since the car is now both stopped and facing left, the right wall of the car is in the way of the loose objects (Cantina, 2005). At that moment everything flies towards the right wall, and the loose objects crash hard against it (Cantina, 2005). If it wasnââ¬â¢t for seat belts, the driver and the passenger(s) would also smash into the right wall (Cantina, 2005). However despite wearing seat belts, a passenger can still feel the force that is pushing him towards the right side of the car, in this situation. If the car was extremely heavy, or was traveling at a considerable speed, then the force of the crash would be greater Cantina, 2005). This is because of Newtonââ¬â¢s second law, F=ma, the larger the acceleration or mass, the greater the force (Cantina, 2005). This makes it obvious that loose objects in vehicles are dangerous and should be placed in compartments provided (Cantina, 2005). Everything that has been explained above can be proven right by conducting a firsthand investigation. However in this investigation, one does not have to make a sharp turn or have loose objects laying around the car. One can simply place their sunglasses on the dashboard and observe its movement whenever the car turns. If the car turns right then the sunglasses will move to the left and vice versa. This is a very simple yet accurate example of inertia in the carââ¬â¢s frame of reference. How to cite MOving About, Papers

Answer: Description of health issues: Dementia is a common health issue in elderly people and it significantly interferes with normal daily life activities. The disease is associated with gradual deterioration in memory, communication, reasoning and judgment skills, ability to focus and visual perception. However, cognitive problem is not the only challenge for care givers of elderly people with dementia. In nursing homes, it has been found that 50% of elderly people have dementia and recognizing and assessing pain such people is very challenging (Hadjistavropoulos et al., 2014). Many barrier to pain assessment is seen because of personality changes, memory loss and impairment if judgment and abstract thinking skill in elderly people. Error in assessment might also occur because sometimes symptoms attributed with dementia are actually an indication of pain in patient. For example, dementia patients may display aggressive behavior when they experience pain and the care may mistake it as a symptom of dementia (Lichtner et al., 2014). Hence, considering unique challenges in recognizing pain in dementia patient, this report proposed developing a health promotion strategy to improve pain assessment of elderly people with dementia. The focus is mainly on female patients with dementia as women are at greater risk from dementia than men (Knapton, 2017). Evidence based strategy for health improvement: The evidence based strategy that is proposed for mitigating the barrier in pain assessment and managing pain in elderly patient with dementia is the use of sense-making theories to interpret pain in nursing homes. The strategy of using intuitive perception is considered important to mitigate the barrier to pain assessment because pain assessment tool does not provide the information that nurse need to recognize pain in patient. Hence, using the sense making theory may help to develop the intuitive knowledge of carer in nursing homes and improve their decision making regarding pain recognition and management. The theories of sense-making focuses on giving meaning to experiences and interpreting information from those experiences (Dowding et al., 2016). Hence, this approach can be used in nursing home to use intuitive skills to recognize the characteristics of cognition in elderly women dementia. This form of decision-making is highly dependent on interaction with patient and the highe r interaction, the more information is gained regarding level of pain in dementia patients. Mamykina, Smaldone, Bakken, (2015) also support the benefits of the sense making theory in management of chronic disease by using the framework of sense making for diabetes self-management. Hence, instead of relying on the technology and clinical tools, this health promotion project encourages carers observe patients behavior and make sense of those information to manage chronic diseases. Overview of the strategy: This health promotion strategy proposes developing the intuitive perception of nurse or care or elderly people with dementia by the application of the sense making theory and supporting them to recognize and assess pain in such patients. Sense making is mainly dependent on a persons ability to make sense of the phenomena (patients behavior or expression in response to pain), construct mental representation of that phenomenon and using this to guide action. This enables developing a pattern related to behavior of dementia patients during pain, discovering connections associated with pain and then engaging in appropriate management activities to reduce pain interaction, the more information is gained regarding level of pain in dementia patients (Mamykina, Smaldone, Bakken, 2015). Hence, in the context of recognizing pain the in dementia patient, the implementation of this health promotion intervention is dependent on extensive training of staffs and their experience in caring for deme ntia patients in nursing home. In nursing home, sense making theory can be applied for recognition of pain in dementia patients in the following ways: Nurses must be trained to build mental patterns of the patients behavior with time. The advantage of this approach is that it will support the nurse to identify the behavior or characteristics that indicate pain. Three necessary sense making strategies that will be necessary for the nurse to recognize pain will include perception of new information related to expression of pain in patient, development of inferences from certain behavior of patient and carrying out appropriate strategies to manage pain (Dowding et al., 2016). There is also need for collective work of the team because cognitive activity cannot be individual person and group of individuals monitoring the patients behavior and health status may give good information regarding identification of pain and cause of pain (Goodwin et al., 2014). As pain assessment in elderly dementia patient requires more cognitive power, it is necessary that organization routines and boundaries also support carers to devote time in identifying behavioral patterns of dementia patient. Therefore, redesigning the system of care will be necessary to promote care of elder adults with dementia (Callahan et al., 2014). With the use of sense making approach, the nurse can collect cues related to patient patterns of pain. Some of the signs of pain may be recognized by behavior, vocalization of pain and scores on formal assessment tools. Hence, pain assessment tool is not totally excluded in this intervention, instead this also informs about the pattern related to pain event in elderly patient. In response to this information, clinician or nurse can identify the experience as pain and implement necessary action to manage such patient situation (Dowding et al., 2016). Health promotion approach model to be used for the strategy: The above mentioned strategy is mainly based on the model of recognition-primed decision model (RPD). This model defines the process needed for effective decision making during complex situations. It can regarded as an effective health promotion approach model for dementia patients because this model also supports taking intuitive strategies such as pattern recognition to take proper action. The role of cognition is critical in improving safety of patient in nursing home setting and the RPD model will support the nurse to effectively recognize and manage pain of elderly adults (Lighthall Vazquez-Guillamet, 2015. The model will promote health promotion activities for dementia patients in nursing home because it also combines the intuitive and clinical information processing components to improve health status of individual. This is relevant to the sense making approach needed for recognition of pain and using this model as a framework will give direction to nurses or carer regarding the pain recognition and assessment process. Description of health promotion activities: To successful develop the skills of nurse in pattern recognition related to pain recognition in elderly dementia patients, the following health promotion activities will be necessary: Firstly, it will necessary to develop the cognitive skills of nurse and carers so that they engage in pattern recognition and develop intuitions regarding the behavior that is an indication of pain in patient. Hence, training sessions will mainly use the cognitive forcing strategies to encourage nurse to monitor dementia patients and increase their competency in using heuristics for identification of pain (Lichtner et al., 2016). The key resource required for this health promotion activities include pain assessment tool, appropriate behavior characteristics form of patient, training materials related to strategies needed for pattern recognition and follow up form to inform about patients behavioral patterns. The training and material and pain assessment tool is critical for carers because training material will enable nurse or carer too characterize patients behavior related to pain and tools will give information regarding pain levels and type of pain (Newton et al, 2014). Secondly, behavior characteristics form will inform the staffs about the individual response of patients to pain and this will be useful in communicating the information to other staffs involved in care of that patients too. The training activities will be collected prior to the implementation of activities and the process of intuition to collected cues related to pain will be done in nursing home. This health promotion project will need investment in the area of relevant pain assessment tool for dementia patient and covering the training cost. Evaluating the success of the strategy: The main objective of the use of sense making in recognizing pain in elderly people with dementia is : Eliminate the barrier to recognition of pain and assessment of pain such as misinterpreting patients behavior in response to pain as symptom of dementia Getting all the cues related to specific behavior that is an indication of pain in patient Recognizing the factors that is the cause of pain in patients (Lichtner et al., 2016) The success of the project will be determined by taking the feedback from the nurses or carers regarding the use of sense making approach for pain recognition. If they express that challenges in pain assessment has reduced after this approach, then this intervention can be continued for long term too. The next aspect is related to evaluating the outcome of dementia patient after the recognition of pain. Insufficient training or education regarding effective pain assessment is often a barrier to pain recognition and the outcome of patient may give an indication whether cares have been successful in conceptualizing pain situations of dementia patient or not. Secondly, the level of use of pain assessment tool is also critical for this pain assessment project because pattern recognition is also dependent on effectively measuring pain levels (Chacko, 2014).
