Motivation behind Behavior Essay Example | Topics and Well Written Essays - 1750 words

Motivation behind Behavior - Essay Example The topics of the course were very diverse. They ranged from an overview of sustainability aspects including engineering perspectives, health, corporate and consumer responsibility to planning, designing, and measuring sustainability. They offered broad knowledge and adequate case studies such as Offshore Wind Farm negotiation that were practical and taught me how to plan and execute negotiations with stakeholders for a sustainable environment (Department of Urban Studies and Planning, Massachusetts Institute of Technology, 2005; â€Å"PON at Harvard Law School – Offshore Wind Farm Negotiation,† 2008). Moreover, they also enabled me to understand how to perform an analysis of a project impact. Leadership lessons taught me how to motivate others, identify developing conflicts, and solve them. The Strength Deployment Model taught me to identify positive things from people’s behavior, learn the motivation behind their behavior, and use appropriate language to motivate them towards a sustainable environment (SDI, 2015). Concepts in this lesson helped me understand myself and my roles as a leader in sustainability. It taught me the value of being aware of happenings in the society or the importance of an aspect such as the climatic change to society. Some of the main aims of leadership include actively solving the issue of how to organize the collective effort for optimal outcomes. It also taught me that working with people is challenging and I now know the challenges to expect and what to do to create a motivating environment for everyone to accomplish sustainability measures in society.

Developing A Warranty Cost Model

Developing A Warranty Cost Model Chapter 2: literature review. 2.1. Introduction to Reliability: The reliability expression may sometimes be unclear in general logic due to the differences in understanding it among customers. Each customer can define reliability from a different point a view. As an example; a customer may define it as cheap product which has a long guaranteed life cycle period and in the meanwhile works hardly enough. Whereas another customer may define it as a reasonable price product which has a life cycle period and will definitely work as intended. (Institute et al., 1968) The concept reliability is very clear and understandable in the practical and industrial world. Reliability of a product, process, or system is the probability that it will perform as specified, and under certain condition, for a specified period of time.(2Blank, 2004) Reliability is known as the likelihood of a product, machine or a component, to keep doing its intended task without breaking down under precise conditions for a given period of time. (Yang, 2007) (Yang, 2007) The above expression holds three significant essentials to ensure the full understanding of reliability: To know the planned function or task of a product, machine and component. To know the planned duration specified relating to a product, machine and component. To know the environment surrounding where the product, machine, and component, suppose to be working at. Knowing these three essentials conditions will allow us to estimate the product, machine or component reliability capability from the first instance. 2.1.2. Reliability Engineering Studies: The purpose of reliability engineering studies is to control, or to make sure that a product, machine or component will be reliable under normal operation in a specified studied manner, as well as away from breaking downs. (Smith, 1972) Reliability engineering studies are science used to minimize the outcome effects and possible behaviour which will result in maximizing reliability. There are three necessary conditions to achieve the previous statements: To build a maximum reliability consideration into a product, machine and component, during the design and development stages; this consideration is known to be the most critical point due to its responsibility in inherent reliability. To cut down production process differences; this will guarantee that the process will not deliberately degrade the inherited reliability. Once a product is manufactured. A well maintained operation should be commenced; this will prevent the performance degradation and will extend the product life.(Hartman, 2007) These considerations are presented within a large selection of reliability techniques, as an instance; reliability planning and specification, fault tree analyses, accelerated life testing, degradation testing, reliability verification testing and warranty analysis.(Yang, 2007) 2.1.3. Reliability Main Factors: To judge on the reliability of any product, there are factors should be known, as an instance: Intentional usage or application. Product, machine and component specification. Price. Customer expectations. Level of inconvenience caused by product, machine or component breakdown. 2.1.4. Reliability Measurements: In a view of the fact that reliability is measured by probability or likelihood, any effort to measure it will engage the usage of statistical methods. Therefore statistics are very important tools in relating to reliability studies. (Yang, 2007) 2.1.5. Reliability Formula: Warranty and reliability share the same patterns for an economic sense to be observed. Reliability has been identified as the likelihood of a product to keep performing its intended task without breaking down. R= reliability. P (s): success probability. N: number of attempted trails. S: number of success. F: number of failures. Reliability mainly presents the successes and failures in a process, where a good economic warranty cost model has high accuracy in reliability prediction.

[ONLINE] Available at: http://www.reliasoft.com/newsletter/v8i2/reliability.htm. [Accessed 19 March 2011]. 2.1.6. Reliability Improvement: There are many ways by which the reliability can be affected, below are two ways: Quality is the integration of features and characteristics of a product or a service, to enable us to meet the needs and specific requirements. Repetition of the same task causing financial and labor waste. (6Condra, 2001) 2.1.7. Reliability Applications: Various phases of a power plant such as construction, production and maintenance shall apply the reliability data analysis. Such a data might be (Heyman, 1988)applicable for production planning, benchmarking , trend analysis, plant components improvement, risk issues, RCM , spare parts optimization, Design review , Structural reliability. (Heyman, 1988) Data on existing units can be effectively useful for benchmarking the unit performance, during RCM, failure preventions, the spare parts optimization.(Heyman, 1988) 2.1.8. Reliability Prediction Science: It is considered to estimate the effects of the choices made prior the system is built or put into service. Reliability prediction handles the analysing of products with the help of models better than real systems to supply a solid foundation for testing, analysing, planning, manufacturing, and estimating reliability. An ideal example of reliability prediction is to predict the system of specified design and specified group of components in an ideal working environment. At the end of the prediction the reliability of the same system should be tested in a different surroundings from those which data and prediction were obtained from earlier.(3Blischke and Murthy, 2000) Reliability prediction procedure is attempted at the very first steps of improving a program to hold up the design procedure. Commencing a reliability prediction helps in supplying clear demands of reliability enhancement within the improvement stage, and the knowledge of the possibilities of failure of the equipment in its operation life. The advantage of applying reliability prediction, machinery designs are able to develop, money is saved rather than spending on poor designs and time is preserved concerning testing. A widely used way for prediction the reliability of machinery is based on database usage, however this way is not probable due to variety types of failure rates which dramatically happen to similar products.(Geitner and Bloch, 2006) 2.1.9. Objective of Reliability Prediction: The importance of reliability prediction lies down under several points: The reliability prediction should be implemented as an assurance program in different sections of a plant. Repairing decisions are taken when and where problems appear.(Kececioglu, 2002) 2.1.10. Taxonomy Related to Reliability: Availability: It can be defined as the probability that the component will function at any random time. Mean time to failure (MTTF): The time that elapses until a failure occurs. Mean time between failures (MTBF): It is the average time between failures. It is used for repairable systems. Failure Rate: The failure rate in a time interval which is the probability that a failure per unit time occurs in the interval given. Hazard Function: The failure rate limit as the interval approaches zero.(Pham, 2006) 2.2. Reliability Centred Maintenance: The word maintenance from the engineering point of view is: to take the necessary action to maintain or restore equipment and machinery, or system to determine the practical requirement to achieve maximum validity. This includes corrective maintenance, preventive maintenance, and predictive maintenance. What is maintenance? Definition and Meaning. 2011. What is maintenance? Definition and Meaning. [ONLINE] Available at: http://www.businessdictionary.com/definition/maintenance.html. [Accessed 19 March 2011]. Reliability centred maintenance or (RCM) can be expressed as an advanced study into maintenance, which joins the maintenance of interactive applications, preventive, predictive, and proactive, as well as the formation of plans to make the most of the life of the product, and also to ensure proper function for the product, machine and component at the lowest possible cost.

[ONLINE] Available at: http://www.plant-maintenance.com/RCM-intro.shtml. [Accessed 19 March 2011]. 2.2.1. Preventive Maintenance: Preventive maintenance is the programme of planned maintenance, which aims to prevent the collapse and failure. The main objective of preventive maintenance is to prevent the failure of equipment before it happen. It is designed to maintain and improve equipment reliability by replacing worn components before they fail in practice. Preventive maintenance activities include equipment checks and repairs, partial or complete checks at fixed intervals, oil changes, and lubrication and so on. In addition, workers can record equipment deterioration so they know when to replace or repair defective parts before they cause system failure. It would be an ideal preventive maintenance program to prevent all equipment failure before it happens. Preventive Maintenance. 2011. Preventive Maintenance. [ONLINE] Available at: http://www.weibull.com/SystemRelWeb/preventive_maintenance.htm. [Accessed 19 March 2011]. 2.2.2. Predictive Maintenance: Techniques help to determine the status of equipments in service in order to predict when you must perform maintenance. This approach offers cost savings over routine preventive maintenance. What Is Predictive Maintenance?. 2011. What Is Predictive Maintenance?. [ONLINE] Available at: http://www.wisegeek.com/what-is-predictive-maintenance.htm. [Accessed 19 March 2011]. 2.2.3. Terms and Goals of Using Reliability Cantered Maintenance: The majority of maintenance organizations classify the goals of using (RCM) by the below listed steps: Scheduling the tasks by its priority. Consider the safety prospective. To be familiar with the machinery capabilities; each type of machinery will have different performance type. Knowing the failure causes; to recognize when the right moment to reduce it is. Using skilled staff; to help out in scheduling priorities. Practicing preventative tasks; to help in knowing the machinery status. Disposing and replacing the damaged components; to ensure the effectiveness of the other related parts. Standards must be identified for each step mentioned above. It is important that the steps are done by the same staff who are responsible of the function and operation of the plant.(Tweeddale, 2003) The conditions to develop a sufficient (RCM) program depend on the success of using the observation and statistical methods, because sometimes both methods depend on each other. 2.3. Failure Mode and Effects Analysis: Mechanical failures are introduced as any significant changes regarding size, shape or material characteristics in a system. The first and main responsibility of any mechanical designer is to make sure that the design produced is capable of doing its function properly, meets the designated life time and most important is to be competitive in the market. Estimating and identifying all possible modes of failure which may restrict the functionality of the design will ensure the success in designing. The designer must be familiar with the variety collection of failure modes presented in the work sites as well as the circumstances leading to it, so the designer becomes ready to prevent failure from occurring once again. The designer should preferably have an on hand experience to investigate predictable failures in a professional manner, thus failures could be prevented in future. It is clear that the failure analysis, prediction, and preventative are significant to be known to every designer.(5Collins, 1993) The term behind the failure can be known as the failure to meet some specific performance measurements. Different between definitions terms such as defects, malfunction, fault and reject are usually vital in comparing causes of failures, as well as in the categorizing and analyzing of provided information. The different between the terminologies is mainly to define the types of failure, reasons, and level of failure. For any introduced definition of failures there are no doubts in introducing reliability. Because the failure is the absent of the specification and so changes in performance capabilities occur. (Smith, 2005) The estimation of the data could be done by two methods, first by using history data; this will enable us to have a look at similar machinery which may had experienced identical problems, warranty data, and customer feedback. Second method is conducted, by using several mathematical methods, models and simulations. Dealing with (FMEA) does not always mean that one way is better or more accurate than the other; both of the methods can be used if applied correctly. The proper way in commencing (FMEA) will result is providing helpful data which can help in reducing the hazards relating to work load in a system, product and service. The (FMEA) is one of the most efficient ways considered in preventative maintenance. The (FMEA) will help in having knowledge about what is suitable correction tasks should be done to keep failures away from happening. An effective and successful (FMEA) system could be recognized by meeting these objectives, first recognize the known and possible failures modes, and then reasons of failures. Schedule the failures modes according to the highest risk level, and finally follow up the work done to ensure the correction of the failure.(Stamatis, 2003) 2.3.1. When and Where To Use Failure Mode and Effects Analysis: The (FMEA) procedure is extensively used in different stages, regarding product designing and manufacturing processes. It offers a well organized structure and an easy way to communicate amongst the team of manufacturers. It can be used as well in developing services which will help production process.(McDermott et al., 1996) Traditional failure modes and effects analysis (FMEA) are mainly used models in warranty cost among other models in the automobile industry. (Majeske, 2003) An essential term to inherent reliability into a product or system is by recognizing the failure causes, and making sure they are removed or that their likelihood of happening once again is low. This thought can be done by conducting tests, or logically by using models. Failure mode and effects analysis is a planned way in clarifying the origin of failures modes, and it is considered to be a sufficient reliability schedule, especially it links to reliability development throughout design stage.(7Denson, 2006) 2.4.4. Hazard and Operability Study (HAZOP): Risk analysis is an orderly and systematic method for Examination system and risk management. In particular, are often used as a risk and operating Technique to identify potential hazards in the system and identify interoperability problems. It assumes that events are caused by the risk of design or operating intentions. This approach is a unique feature of risk and vulnerability to treatment methodology that helps to stimulate the imagination of the team Members when exploring potential deviations. Figure (2) shows a sample of HAZOP system.(Organisation and Safety, 1988) Figure (1) a sample of HAZOP system Hazard Operability Studies (Hazops) 1 of 2. 2011. Hazard Operability Studies (Hazops) 1 of 2. [ONLINE] Available at: http://www.lihoutech.com/hzp1frm.htm. [Accessed 19 March 2011]. 2.3.2. Failure Prevention: Failures are predictable, sooner or later all products, machines and component will experience failure due to many reasons.(Yang, 2007) In any engineering system failures are expected. The effects of failures differentiate from little inconvenience costs to financial drops. Failures happen due to various factors, such as: Bad engineering design. Manufacturing process errors. Insufficient testing. Human mistakes. Poor maintenance. Misuse. In order to reduce failures or breakdowns in any engineering systems, there are some methods should be followed: Identify the cause and the way the failure happened. Identify how many times do the failure tends to repeat. Reliability handles the failure concepts in details via different statistical approaches. Whereas safety tries to study, specify, measure, determine, and analyze the failure.(Verma et al., 2010) 2.4. Introduction to Hazard: The accurate understanding of hazard is appreciated due to its criticality. It supplies us with the base foundation of a system safety. Hazard analysis is conducted to identify hazards consequences, and hazard main factors, As well as to determine the risks facing the system. To carry out hazard analysis in a proper manner, it is essential to recognize what causes hazards and how to define hazards. Understanding the hazard character is an important issue to improve the skills needed to identify potential hazards and their results in a system design.(Ericson, 2005) 2.4.1. Hazard Analysis: This analysis involves describing the complete process first, and then collecting the answers for a set of systematic questions. The purpose is to identify how exactly the deviations from the design can arise.   These deviations are further assessed by any negative effect of their consequences on the safe and efficient operation of the plant.   The assessment would provide a basis for any action to be taken to cure this situation. From an engineering point of view, hazard analysis process is the best tool for analyzing reliability data. It can be used to make conclusions about the reliability of a component. (12002) 2.4.2. Survival Analysis: Survival function, also known as a reliability function of the survivors, is a property of any random variable that maps a set of events, usually associated with failure of some system. 2.4.3. Hazard Rate Function: Hazard rate function can be obtained by an equation which assumes a constant hazard rate. 2.4.5. Bathtub Curve: Figure (2) illustrates the bathtub curve which demonstrates the product failure rate against time. Any product cycle life can be divided into three separate durations: The first duration (early life): This duration where the failure probability is decreased to minimum. . It what happens in the early life of most new products, sometimes the first period is mentioned as the mortality period. The second duration (normal life or useful life): This is represented in the graph by a flat line. Failures and breakdowns happen randomly within this duration. In this period the failure rate tends to become somehow constant. During this period the lowest failure rate is observed, so it is the most appropriate time to make reliability predictions. The third duration (wear out): this begins where the slope starts to rise till the end. This typically happen to products when they get old, thus the failure rate increases. Wear out is usually caused by break down due to various reasons such as physical wear and stress.(speaks, 2005) Figure (2) a bathtub curve. A Brief Introduction to Reliability. 2011. A Brief Introduction to Reliability. [ONLINE] Available at: http://www.weibull.com/LifeDataWeb/a_brief_introduction_to_reliability.htm. [Accessed 19 March 2011]. 2.5. Statistical Models for Life Data: Statistical models for life data such as weibull distribution, survival analysis and warranty help in producing high accuracy in prediction. The automobile manufacturing having relied heavily on warranty interval in its warranty provision inclines more in reliability and therefore seek such analysis. (Ward and Christer, 2005) 2.5.1. Weibull Distribution: The weibull distribution is named after a Swedish professor Waloddi Weibull. He explained the ability to use the weibull distribution in small sizes measurements and it is easiness to supply an accurate model for a broad data sets. At the beginning of his exploring weibull distribution he faced some obstacles and doubts form his colleagues. However, the weibull distribution has ended now to be widely practised in reliability.(8Dodson, 2006) A reason for the wide spread of the weibull distribution is that it has a large different shapes, which makes it easy to fit any data. Also, it is perfect to show the weakest connection of a product. For example, if a system has more than one part, the weibull distribution will present each failure time of each part at the same distribution no matter how insignificant they are .(Nelson, 2003) Figure (3) is a sample of weibull a distribution plot.

Kaplan and Paul Meier. It estimates the survival function. In engineering this method is used to measure the time until failure of different products, machine and components. Kaplan EL, Meier P.

Formulation: The probability density function is: Where Mean time to failure = Or, where 2.5.4. Disadvantages and Advantages of Statistical Method: Cost; studying and analyzing a quantity of data of different products within a system are an expensive job. The results revealed are not sufficient enough to build an understanding of the type of maintenance needed in this particular situation. The only disadvantage of the observation method appear is when applying it carelessly and without keeping record of foundings, this will result in mixing up different judgements.(4Chalifoux and Baird, 1999) 2.6. Introduction to Warranty: Warranty is a provision for a seller to provide assurance to a buyer that the product will perform as implied. (Zhou and Tang, 2008) Warranty brings confidence to the buyer; automotive vehicles like any other automated system consider warranty to a buyer. (Wu and Li, 2007) Unlike the quality loss function which assumes a fixed target and accounts for immediate issues, warranty loss occurs during the customer use. (Zhou and Tang, 2008) In automotive industry, data is tracked and analyzed regularly (Zhou and Tang, 2008). The interval can be evaluated on the basis of their costs. The effect of warranty especially in the context of the interval, affects the performance of the company especially if the number of returns on warranty is high. (Wu and Li, 2007) Neglecting the fact that warranty cost is a result of conflict between the customer expectation and the performance of the product, the interval of the warranty liability disturbs the economic sense of warranty. (Wu and Li, 2007) Warranty costs have in many companies been positioned as operational costs. (Ward and Christer, 2005) The impact of warranty in the whole business performance has challenged vehicle manufacturers to develop vehicles that are less costly to repair (Metric: Warranty $s) and are more reliable within a longer period of time. (Metric: annual failure rates, AFR) For this purpose to be done, warranty cost models that make the impact of reliability on cost and costs associated with repair of specific failure modes should be economically healthy. (Wu and Li, 2007) 2.6.1. Warranty Probability: The ratio as Pw is termed as the warranty probability (Ward and Christer, 2005). The warranty probability is the ratio of the number of complaints N against the total number of products Tp. Pw Another factor that is important in warranty cost analysis is the complaint factor. (Ward and Christer, 2005) The complaint factor is the ratio of the actual number of complaints and the potential number of complaints where the actual number of complaints is the number of actual complaints fixed. (Ward and Christer, 2005) The method for calculating the warranty probability depends on product performance and customer expectations. (Wang et al., 2010) The distance of performance is a function of the warranty interval. (Ward and Christer, 2005) It is supposed that as time passes, the distance of performance increases, this is the common feature referred to as mileage. In motor vehicles the time age of the car has been consistently assumed to be a factor representing its use. (Manna et al. 2008) Despite the fact that mileage can be determined, the correlation between mileage and age of the car is strong and positive. (Manna et al. 2008) Since vehicles manufacturing designs and model change with time, the automobile industry prefer attaching warranty to age of the vehicle rather than calibrated mileage. Warranty is a key factor in bringing confidence to a buyer. The higher the warranty time, the more the confidence is the buyer. (Manna et al. 2008) 2.6.2. Warranty Distribution Analysis: Feedback from warranty returns provides a solid basis in determining use failure distribution. (Murthy, and Blischke, 2006) The time interval as a factor contributes significantly to predictions. The warranty intervals are the most solid factor that can be used in assessing the failures prediction. By maintaining warranty and assessing failures for a longer period of time, more knowledge on the performance especially for automated systems is achieved. (Murthy, and Blischke, 2006) Reasons for carrying out warranty data analysis are the following: Forecasting warranty claims. To determine risk assessment and monitoring. Reliability assessment.(12002) 2.6.3. Reduction strategies for cost drivers There are two factors that have been identified as primary warranty cost drivers. The number of occurrence of an event which can be noticed by the analysing failure rate and the cost of the process are the identified cost drivers. (Attardi et al., 2005) The strategies employable for reduction of costs are by reducing the factors. (Attardi et al., 2005) 2.6.4. Cost model in product development The cost model has been used in product development in making economic sense of organizational existence. (Karim and Suzuki, 2005) Through its impact in influence of decision making by providing design alternatives that come handy in warranty cost, the model establishment should be in advisory of the product development through calculation of estimates of product total warranty cost. (Aldridge, and Dustin, 2006) Difference in warranty costs based on design alternatives provides a short projection of the optimized design that maintains both customer confidence through warranty and economic advantage to the organization. (Attardi et al., 2005) Identification of necessary product features, capabilities and diagnostic tools that are required in automobile projected warranty savings for the warranty intervals is achievable through the cost model in product development. (Aldridge, and Dustin, 2006) Under the foundation of the cost model, the risk involved in the warranty interval can be evaluated by analyzing the risk involved in an extension of warranty in automobiles. (Aldridge, and Dustin, 2006) It should be taken into consideration that the cost model economic impact is dependent on the period of warranty especially with automobiles that are known to wear and tear. (Karim and Suzuki, 2005) Chapter 3: case study (from notes given by doctor) Introduction: Field data in the automotive industry often comes in two types, the first is grouped data expressed by months in service. The second is ungrouped data available from company owned but customer operated fleets and expressed as miles to failure. In many scenarios, data which comes from late stages have a greater importance over the former because of the following reasons: Mileage is more objective measure of the component life than time in service. There are types of failures are not tracked by the warranty system. The complexity of censoring mechanism in relating to reliability analysis of grouped warranty data. Therefore, this theoretical case study will focus on the analysing of ungrouped mileage data which is not represented by time in service, because it comes from the company owned fleets. Aim and objective: To discuss a procedure to estimate the censoring mileage and the reliability function for a component of interest (e.g.: battery). Data: Table 1 shows a format of failure data from a customer operated fleet. The vehicle mileage is reported only at failure or service events.

Asteroids Essay -- essays research papers

Asteroids In our solar system today there are over 30,000 asteroids flying around in all direction colliding with other asteroids and planets, without a care about the destruction they might convey. Our planet Earth is caught right in the middle of all of this action and is liable to entire extinction of any life forms on the planet if a large enough asteroid crosses its path. Any single asteroid has the possibility to erase thousands of years of history and wipeout the human race, as we know it. Asteroids are large or small chunks of rock and metal flying around space up to speeds of 80 000 km/h. These chunks were believed to have formed millions of years ago during the "big bang". These rocks didn’t form any planets and were stuck floating around space on their own or in the gravitation of the asteroid belt. This asteroid belt is approximately 300 million miles from the Sun and it contains thousands of asteroids; some being miles in diameter. Another theory of the formation of asteroids is that a planet between Mars and Jupiter once existed and after many years it exploded into thousands of pieces that are still revolving around the sun in the form of an asteroid belt. Other asteroids are formed when large meteors collide with large asteroids creating more small ones. These meteors can also collide with planets breaking off chunks of the crust into space. Ceres is believed to be the biggest asteroid that was in space at one point in time. Ceres was believed to be 600 miles wide, making up 1/3 of the total mass of all asteroids. Ceres was the first asteroid discovered and was found in 1801. There are two main types of asteroids; the first dominates the outer part of the belt and are found to be rich in carbon, the second group are located in the inside of the belt and are found to be rich in minerals. The average temperature of the surface of an asteroid is approximately -73 degrees C. Many people don’t know that over 50,000 small asteroids called meteors hit the Earth every year. These meteors are the outside layer of larger asteroids that have been chipped off or are the surface of other planets that have detached from their positions when hit with larger asteroids. Asteroids sometimes align with Earth when meteors flying through space collide with other asteroids in the belt causing pieces to break off and head in all directions. ... ... wide and found within 8 million kilometers of Earth. It is very probable that a large asteroid will hit the Earth in the future because of the planet’s past experience with asteroid collisions. Scientists estimate that an asteroid more than 800 m in diameter hits the Earth every million years and a smaller one hits every century. An asteroid bigger than 1 km would mean the end of about 30% of the World’s population. This size of an asteroid would be the equivalent explosion to 2 million Hiroshima bombs. This explosion would cause destruction of all living creatures within a hundred mile radius as well as blocking off the Sun with dust and rock particles for weeks or even months. Asteroids are probably the deadliest force that our solar system can produce, one strike could put man back in the dark ages and would kill almost the entire population of our planet. It is for this reason that scientists should focus more on understanding asteroids and research more into the defense of our planet. At the moment we only know where a fraction of the asteroids out there are. The asteroid that could destroy our planet could only be a year away and we don’t even know it exists.

Monomyth: Hero and Family Versus Loyalty

Monomyth: Fact or Fiction? Does every story truly follow the common stages of monomyth? Joseph Campbell first describes the monomyth in his book â€Å"The Hero With a Thousand Faces† written in 1949. In William Faulkner’s story â€Å"Barn Burning† one can look close enough and see the stages of monomyth. In â€Å"Barn Burning† the loyalty to family versus loyalty to the law is tested. The basic structure of a hero’s journey, in this case Sarty, is shown through the three stages Campbell explains.Campbell’s monomyth starts with a departure, initiation, and return. Sarty is faced with all three. Sarty is given a call to adventure, refusal to call, and a crossing of the first threshold. His call to Adventure was while the family had to go to a new place. He and his family were forced to leave by the Justice, he said to them, â€Å"This case is closed. I can’t find against you, Snopes, but I can give you advice. Leave this country and don ’t come back to it† (504). Sarty’s refusal to call is when he hopes it’s all over.All the running and breaking the law with his father he gets so sick of having to take up for his father. After they left town his father asks, â€Å"You were fixing to tell them. You would have told them. † Sarty answered in a whisper, â€Å"yes† (505). The family was living on DeSpain’s land and that is Sarty’s crossing of the first threshold. The initiation in the story is when the hero is initiated into true heroic stature. Sarty faces the road of trials, atonement with the father, and the ultimate boom. The trial he faces of not knowing if he should keep helping his family.His father tells him to go get oil and as he’s going he’s thinking, â€Å" I could keep on, I could run on and on and never look back, never need to see his face again. Only I can’t. I can’t. † (512). The father figure that the family has t o answer to is DeSpain because they are on is land. The ultimate boom is when Sarty actually tells DeSpain what his father is doing to the barn. Sarty cried, panted. â€Å"Where’s†¦Ã¢â‚¬  â€Å"Barn! † he cried. â€Å"Barn! † â€Å"What† the white man said. â€Å"Barn? † â€Å"Yes! † the boy cried. â€Å"Barn! † â€Å"Catch him! † the white man shouted (513).He’s so shook up he can’t even speak clear sentences. After initiation the hero can return in triumph to deserved recognition, although this in itself may not be without trials and tribulations. Sarty refuses to return, takes a magic flight, is rescued from without, and given freedom to live. He takes the magic flight and runs away after telling DeSpain about the barn. He made the decision to run and to not look back, his refusal to return. He made a bold choice to turn away from his family. While running he hears a gunshot, and that rescues him from wi thout.The narrator says,†Ã¢â‚¬ ¦a long, swirling roar incredible and soundless, blotting the stars, and he springing up and into the road again, running again knowing it was too late yet still running even after he heard the shot and, an instant later, two shots, pausing now without knowing he had ceased to run, crying â€Å"Pap! Pap! †Ã¢â‚¬ ¦Ã¢â‚¬  (514). The relief of not having to answer to his father was enough for Sarty, he had his won life to live with any of the people he chose. With that, he was given the freedom to live. One could say that yes, most stories do follow Campbell’s monomyth.Sarty had a hard choice to make in this story but still came out to be the hero according to monomyth. Monomyth is interesting to those who take the time to learn about it. It does apply to stories and movies in modern day. An example would be The Matrix, Star Wars, Lord of The Rings, and even Hangover. There is a fair share of critics, typically saying that not all stor ies are like this. Some may even say this leads to safe movie and book making, thus leading to boring repeats. The same was said about Shakespeare, and his works are famous.

Being Human

As we all know that we are all human beings with uniqueness. Each one of us has different and unique traits, personalities, features and is in total different from an animal or any creatures on the earth. This means to say that we as a human being cannot be like another animal or machine on earth. We have our own set of feelings, habits, likes and dislikes, etc. In fact it can be said that we are probably the only creatures on earth that give priority and importance to relationship and love. However, since these aspects are basically the study of mind we cannot claim that love does not exist among other creatures.Many of us who are used to having pets at home understand the extent to which an animal can express love. However, we cannot judge of the concepts of sin, reasoning, self-awareness, critical thinking, individuality, emotions, empathy, etc. in case of animals. Individuals with psychological problems, sadistic personality disorder, transgressive behavior, cannibals and murdere rs can therefore be considered as being inhuman. There are also instances when human beings under the effect of drugs, neuroscience, introspection, and experiences cause irreversible changes in their traits and characteristics.There are several literatures that talks about the stories of people who were inhuman. There are people who are more â€Å"humane† than the humans around them. This, perhaps, is what really the meaning of being human. There are many people today who are arguing that the present trends in science and technology has kept man and god together. For instance, technologies such as cloning and stem cells have brought in the capability to create a whole new organism. Human beings or for that matter any organism is a result of natures cloning.However, today manmade cloning is a subject of controversy and has raised several ethical questions. There are several arguments made for and against cloning. Some have put forth valid arguments stating the immorality of cl oning. Others use the religion argument saying it goes against God's intention (McCoy n. pag). For any technology to progress and produce beneficial results it is essential that we look at the positive impacts that these technologies may have on the society. There are several researchers who have tries to divine the word being human. For instance, â€Å"Rev. Mitsuo Aoki, Ph.D has said that â€Å"The greatness of aging is to enable you to realize for the first time the deeper meaning of that it means to be human. Not the religious, not that, but more human and it's only in this process of aging that this quality of being human is realizable. You begin to understand the nature of faith, the meaning of hope. And so hope is not about something you achieved, but the life that is always shining in front of you†¦ Is beckoning you. And you only understand that in the process of aging. It's amazing what has been manifested in this process. That beyond all these things is something we call love†¦love. † (KGMB9) Different group of people define this term differently. For instance, â€Å"the constructivists state that Human Nature is a simple cultural artifact†. Sociobiologists, however, are determinists. They consider that human nature – being the inevitable and inexorable outcome of the inhuman ancestry – cannot be the subject of moral judgment†. Human dignity is indeed used to indicate that all human beings have intrinsic worthiness. Every human deserves unconditional respect and is not related to any difference in age, sex, anthropological origin, health, political boundaries, religion, or personal history.In other words it can be said that these are exclusively human. According to the Catholic thought â€Å"human dignity† is linked to an array of human life issues. For instance, it includes health care ethics. In other words catholic moral thoughts are the basic tradition’s understanding of common justice, th e common good, and the right to life and the right to health care in all aspects (Ascension Health). We as human beings have the right to choice and can select what we want in our life. This is not true in the case of animals.Self organizing is another aspect of human beings that is rare in other animals. We live as a social being and participate in the political system. The term being human can be easily understood if we know the meaning of being inhuman. Inhuman means lacking kindness, pity, or compassion or being cruel to other human beings, nature, or any organism. These acts are easily recognizable and are to a greater extent disliked by the majority of us. Besides, the ability to communicate to each other using different languages, the educational background, the society and the impact of religion makes us more human.Morality and immorality is the term that is used to define if a human being can be considered being human or inhuman. Additionally, the concepts of mortality/immo rtality mirror on the promises of life and the predictability of death. It is throughout human development, even for early man called the Neanderthals, this concept has been dominant and in some cultures it is believed that life after death is a reality. The present state of knowledge of the human being is one which has been developed using the special skills and intelligence of human beings.However, it is more by the materialistic thinking of modern technological science. We as human beings need to be more compassionate towards other creatures, nature and think of the development in a sustainable manner. It is also important to realize that we are human beings and not machines. Often times, in today’s run for success and fame, people are not realizing the basic needs of self, family as well as other related organisms. Cooperate world is more like using humans as machines to make profit, to achieve targets and generally think of the human body as being merely an elaborate mac hine which is a real problem.It is essential to realize that we as human beings need to be human to ourselves and other fellow human being with all the non-material aspects of the human being- thinking, feeling, attitudes, emotions, mores, imagination, etc. Work cited Ascension Health. Principle of Human Dignity (2007) KGMB9. The Deeper Meaning of Being Human†¦ Love (2008) McCoy, L. Lloyd's pro cloning essay. (1998).

Capital City of Canada Why Ottawa

Capital City of Canada Why Ottawa SAT / ACT Prep Online Guides and Tips Whether you’re preparing for a geography exam or simply want to learn more about your friendly neighbor to the north, we’ve got you covered. In this guide, we'll answer an important question everyone should know the answer to: what is the capital of Canada?In addition, we'll explain how this place came to be the capital city of Canada and what all the capital cities of the Canadian provinces and territories are currently. What Is the Capital of Canada? The capital of Canada is Ottawa, which is located in Ontario- that is,the province directly above the Great Lakes and the US states of Minnesota, Wisconsin, Michigan, Ohio, and (part of) New York. Ottawalies on the south bank of the Ottawa River, which runs between and defines the borders of the provinces Ontario and Quebec. Opus Penguin/Flickr Together, Ottawa and the city of Gatineau, which is located directly across from Ottawa in Quebec, make up the National Capital Region called Ottawa-Gatineau. This specially designated region refers to not only the cities themselves but also their surrounding Census Metropolitan Areas. Due to Ottawa’s placement between the primarily English-speaking Ontario and the mostly French-speaking Quebec, it is one of the most bilingual cities in Canada. Beloware some quick facts to know about Ottawa, the capital city of Canada: Location: Southeastern Ontario Original Settlers: Odawa tribe ("Odawa" is said to mean "traders") in the mid-17th century Population (2016): 989,567 (Ottawa-Gatineau) Population Rank (2016): Sixth-largest city in Canada (Ottawa-Gatineau) Year Established: 1850 as town of Bytown, 1855 as city of Ottawa Climate: Continental, with warm summers (70℉) and cold winters (15℉) Major Employer: Federal government Landmarks: Parliament Hall, ByWard Market, National Gallery of Canada, Rideau Canal, University of Ottawa Closest US State: New York Closest Big City: Montreal in Quebec A Brief History of the Capital of Canada Ottawa has been the capital city of Canada ever since Canada became a self-governing country. But how exactly did it manage to become the capital of Canada- and why? In 1841, what was originally called the Province of Canada (the present-day provinces of Ontario and Quebec) came under British colonial control. The next 16 years witnessed ongoing disputes over what the capital of the new province should be; contenders included Quebec City, Toronto, Montreal, Kingston, and finally Ottawa. Each of these cities held the title of capital of Canada for varying lengths of time. Here is a chronology of exactly how the capital city of Canada changed in just two and a half decades: Kingston (1841-1844) Montreal (1844-1849) Toronto (1849-1851) Quebec City (1851-1855) Toronto (1855-1859) Quebec City (1859-1865) Ottawa (1866-present) It was clear already by 1857 that the decision of where to place the capital of Canada was going to be difficult and time-consuming. At this time, Queen Victoria was asked to select the capital city of Canada. Her choice of Ottawa- a fairly small and newly incorporated city- surprised many. Still, Ottawa had a lot of promise: it was starting to experience economic growth and was home to an impressive railway system; it also had a long history of trade due to its location near several rivers. Butnot everyone agreed with the queen’s pick,which led Toronto to remain the capital for another two years followed by Quebec City for another six years. It wasn’t until 1866 that Ottawa was officially designated the capital city of the Province of Canada and began to hold Parliament. In 1867, the Province of Canada became the Dominion of Canada, making it an official, self-governing colony of the British empire. This also meant that Ottawa was the first (and so far only) official capital of Canada as we know it. What Are the Capital Cities of Canada? We now know that Ottawa is the capital city of Canada, but what about the capital cities of all the provinces and territories within Canada? Similar to the United States, where there is a capital city for each state, Canada has capital cities for all 13 of its provinces and territories. The following chartdepicts the capital city of each Canadian province/territory and its population from the 2016 census. Provinces and territories are listed alphabetically. Province/Territory Capital City Capital City Population (2016) Provinces - - Alberta Edmonton 932,546 British Columbia Victoria 85,792 Manitoba Winnipeg 705,244 New Brunswick Fredericton 58,220 Newfoundland and Labrador St. John’s 108,860 Nova Scotia Halifax 403,131 Ontario Toronto 2,731,571 Prince Edward Island Charlottetown 36,094 Quebec Quebec City 531,902 Saskatchewan Regina 215,106 Territories - - Northwest Territories Yellowknife 19,569 Nunavut Iqaluit 7,740 Yukon Whitehorse 25,085 Note that while the capital city of Canada (Ottawa) is located in Ontario, it is notthe capital of Ontario itself- thisstatus belongs to Toronto. For most provinces/territories in Canada, the capital city is also the most populated city, but this isn’t always the case. Here are the biggest cities for the Canadian provinces for which the capital city is not the most highly populated: Province Biggest City City Population (2016) Alberta Calgary 1,239,220 British Columbia Vancouver 631,486 New Brunswick Saint John 67,575 Quebec Montreal 1,704,694 Saskatchewan Saskatoon 246,376 What’s Next?
