Classifications of Hybrid Electric Vehicles Essay Example for Free

Classifications of Hybrid Electric Vehicles Essay 1. Technology Although the Electric Vehicles (EVs) have been around since the earliest days of automotive industry, they were not able to live up to consumer demand in terms of price range and charging time until recently. A recent survey has revealed what the consumer demands from EVs. According to a study based on a survey conducted in 17 countries with 13,000 individuals the demanded technology and the result of the study is that EV technology is at a period of its lifecycle where the performance of the technology is not at a level that customer expects. 1. 1. Range Although there is a high consumer willingness recently to either consider to purchase EV or willing to be a first mover when it comes to EV adoption, many of them does not compromise in Range. Despite the fact that the average consumer does not exceed 50 miles per day, the consumer still demands further range capacity from EVs. The majority of the consumers correlate EVs range with conventional internal combustion engine (ICE) vehicles [1]. Also According to Hidrue, M. (2010) â€Å"range anxiety† is the primary concern of a potential EV consumer. As the figure illustrates, although the greater majority (78%) of consumers in the US drives around 50 miles, a big portion of them have expectation for EV to be able to drive around 300 miles. The current technology allows EVs to drive between approximately 100 miles between charges. The only EV that can get close to consumer demand in terms of range is Tesla S (which drives 265 miles) as of 2013. However, the average technology does not live up to consumer demand in terms of drivable range between charges currently. The main constraint for the low range is energy density. According to Deploit (2011), the forecast was revealing that with the battery technology in hand the driving range still would fall short of consumer expectations. 1. 2 Top Speed and Acceleration There are multiple schools of thought about how consumer behavior affects EV market. According to those consumers would purchase new vehicles whose attributes are superior to those of currently in the market, they would not seek alternatives which are worse than what they have currently [4]. As an example Nissan Leaf is rated up to 90 kW of power which is approximately 120 horsepower in ICE which is in line with a large number of compact and intermediate vehicles such as CW Jetta, Toyota Corolla and Ford Focus. There are also better EVs in the market in terms of performance, in example Tesla S series can produce 416 horsepower and can go up to 130 mph on a highway [5]. The reason why EV generally does not go more than that is that high speeds drop the fuel efficiency dramatically. Table. 1 The performance chart of Tesla S [5] 2. Vehicle Architecture 3. 1. Vehicle Architecture. Although there are different frames that can model a vehicle’s architecture, the following one is a comprehensive way to understand the functions and interrelationships of the components. In order to adjust the high speed of the electric machine to the low speed wheels, the torque of the left and right wheels are provided by a differential. Basically, the inverter inverts DC voltage battery into three-phase AC voltage that is required by the electric machine. Furthermore, it is also important to account for losses due to the components, which are not a part of the power chain when analyzing the energy consumption. These auxiliary losses comprise lighting system, comfort system, safety systems, etc. It is also very critical that the maximum voltage of the battery is not exceeded during the regenerative braking, to prevent that from happening the architecture is reinforced by braking resistor [6]. Exhibit 1. Architecture of a typical Electric vehicle [6] 3. 1. System Architecture Electric Vehicle’s architecture is similar at certain points to ICE. Driver interface and command interpreter receives input from users through steering wheel, brakes, and gas pedal and then by considering vehicle speed and vehicle path, creates propulsion. The motion control comprises two primary blocks such as the path controller and energy management controller. Path controller gives forces and moments demands to the force distributor. The energy management controller determines the state of the charge and estimates the overall traction force to be sent to command controller unit [7]. Exhibit 2.

Little Albert and David Reimer: Ethical Analysis

Little Albert and David Reimer: Ethical Analysis Ethics Essay Introduction All psychological studies focusing on human being needs to obtain ethical approval by the Psychology Research Ethics Committee. Psychologist wishing to conduct a research/study must first submit a filled in form of psychology ethics committee application cover page, write up a detail proposal describing the research process and attach any supporting documents. These steps are compulsory prior to research in order to protect participants from inhumane harm. Due to past examples of highly unethical research like the â€Å"Little Albert† experiment and â€Å"David Reimer† experiment, it has triggered psychological societies to issue a code of ethics in psychology which provides ethical guidelines for researchers. The code of ethics includes informed consent, voluntary participation, right to withdraw, accurate reporting, do no harm, debriefing and desensitisation. Experiment 1 – Unethical Reasons The first example of past research that would be considered unethical by today’s guidelines is the â€Å"Little Albert† experiment. The experiment is conducted in 1920 at John’s Hopkins University by behavioural psychologist John B. Watson and his assistant. The purpose of the experiment was to investigate whether fear is something born with or can be learned due to exposure of environmental influences; and if phobia can be developed by classical conditioning. The participant was 9 month old infant, Little Albert. In the experiment, Little Albert was first exposed to various white or furry objects and happenings that usually cause fear. Next, a white lab rat was given to Albert and he showed no fear. Watson then made loud banging sounds behind Albert’s back every time he touched the rat – Little Albert cried. He became upset when he was exposed to the white rat again as he linked the rat with the banging noise produced. First of all, the experiment has breached the â€Å"do no harm† guideline as Little Albert was not protected from psychological harm – the main purpose of the experiment is to test if fear can be developed by classical conditioning. Also, Watson knew that there will be not be sufficient time left to treat any possible fears/harms caused. Secondly, the â€Å"voluntary participation† guideline is breached as Little Albert did not volunteer for the study, he is too young. Little Albert was chosen from the hospital where his mother worked as a wet nurse. She is financially dependent on the hospital for income and feared that she would lose her job if she disagreed Little Albert’s participation. In addition, she received $1 for Little Albert’s participation in the experiment. In a way, she was forced to agree for participation in order to keep her job and due to aid in financial struggles. Thirdly, the â€Å"informed consent† guideline is breached as his mother was never informed about the procedure, the pros cons and withdrawal rights of the experiment. Lastly, the â€Å"desensitisation and debriefing† guideline is breached as there was no removal of ill effects and Little Albert was never treated for his fears as he left the hospital right after the experiment ended. As a result, Little Albert developed fears towards anything that was white fluffy and grown up having a phobia of dogs. Improvements There are guidelines to ensure that the â€Å"Little Albert† experiment could be run ethically. Firstly, the do no harm and desensitisation guideline could be linked together. Watson should have suggested treatment plans to help remove the harm and cause of fear of Little Albert. This is extremely crucial in protecting the participants from future psychological problems that may have a significant impact on their lives. Secondly, Watson should have chosen other babies who didn’t have parents who worked in that hospital, so that they do not feel pressured to accept the request. Also, Watson should not use money to gain agreement for participation. Lastly, Watson should have properly inform Little Albert’s mom about the experiment procedure and make it clear that he had the right to withdraw from the experiment at any time without any problems caused. Experiment 2 – Unethical The second example of past research that would be considered unethical by today’s guidelines is the â€Å"David Reimer† experiment. The experiment is conducted in 1965 at John’s Hopkins Hospital by sexologist Dr Money. The purpose of the experiment was to prove that nurture, instead of nature determines gender identity and sexual orientation. The participant was 22 month old baby, David Reimer. In the experiment, the baby underwent a sex re–assignment surgery where his testes were surgically removed. David (now Brenda) changed his name and was brought up as a female. The plan failed when his family finally revealed her original gender at age 15. First of all, the experiment has breached the â€Å"do no harm† guideline as David Reimer experienced severe psychological harm – he committed suicide at age 38. Also, the experiment has indirectly caused harm to his family: his mom was suicidal, his dad was alcoholic and his twin brother was severely depressed committed suicide at the end. Secondly, the â€Å"voluntary participation† guideline is breached as David Reimer did not volunteer for the study, his parents were equally horrified by the suggestion of a sex change, but eventually agreed to the procedure. Little did they know Dr Money’s real intention – to use David to prove his â€Å"theory of gender neutrality†, which states that gender can be trained by being brought up in an appropriate environment. Thirdly, the â€Å"informed consent† guideline is breached as his parents were not properly informed of the experiment. They were not told what was going on during the kidsâ€⠄¢ yearly meetings with Dr Money. Fourthly, the â€Å"accurate reporting† guideline is breached. Dr Money wrote a report on his study and claimed that the experiment was a huge success and that his theory is supported, which greatly contradicts the data from previous reports. It is clear that the Reimer family were having huge psychological issues – David wasn’t living up to his role as Dr Money had described in his report. Dr Money has falsified the outcome of the experiment. Lastly, the â€Å"withdrawal rights† is breached as David and his twin brother Brian were forced to travel to Baltimore for yearly meetings with Dr Money until they refused (not because they had the right to withdraw, but because they were too frightened to see him) Improvements There are guidelines to ensure that the â€Å"David Reimer† experiment could be run ethically. Firstly, Dr Money should have suggested a psychiatrist to evaluate David and provide counselling treatment to aid in his acceptance of his true gender. Dr Money should have suggested treatment centres for the Reimer family to visit to remove all negative effects caused by the hidden truth of David’s real gender. Secondly, Dr Money should have debrief the Reimer family of his real intentions of using David as an experimental object is due to selfishness, instead of persuading them to believe that a sex change is indeed the best advice that Dr Money can give. Thirdly, Dr Money should have informed David’s parents of what he did during the yearly meetings. In those meetings, he frightened the twins by using disgusting and inappropriate ways to make a clear cut difference between feminine and masculine. He made David and his twin perform sexual acts and took photos of them naked. Lastly, Dr Money should have accurately report his experiment results. Many textbooks were re-written just to publish his theory that he stated as supported, which in reality just clearly contradicts the whole experiment result when David committed suicide due to depression. Conclusion All in all, when there weren’t any ethical guidelines in the past, unethical experiments can be conducted by psychologists for selfish and illegitimate reasons. It is due to such unethical experiments that urged psychological societies to issue a code of ethics in order to protect the participants from inhumane harm. All psychologist have to strictly follow the guidelines in order to obtain approval to conduct their intended experiment. Due to the lack of guidelines in the past, Little Albert was psychologically harmed that he developed a phobia which was not treated. David Reimer was also psychologically harmed as he was not informed of his original gender until 15 years later where his whole family broke down psychologically. Previously, â€Å"she† was so confused and was often teased about her questionable gender identity, which also impacted on her self-esteem. In reality, both experiments could be run ethically even if a code of ethics was not issued in the early days. However, this is dependent on the degree of common sense and humaneness the psychologist designs the experiment. Referencing Introduces the reader to the fact that psychological research today must follow ethical guidelines. Briefly states what these guidelines are. Explains that there are examples of past research that would breach today’s guidelines. Describes an example of past research that would be considered unethical by today’s guidelines. Explains why it would be classed as unethical i.e. which guidelines are breached and how. Makes specific suggestions as to how the research could be run ethically.

Explains why it would be classed as unethical i.e. which guidelines are breached and how. Makes specific suggestions as to how the second example of research could be run ethically. If this is not possible, then argues why not. Sums up main points of the essay (does not introduce any new information or ideas). Harvard in-text referencing and a full reference list is essential

Green Living: What Is It?

Green Living: What Is It? The earth, as we know it is deteriorating in ways more than one. In order to set it right and restore the balance of events, we need to take an initiate and change our lifestyles to support the planets health. There are many ways by which you can also start to live greenly. The actual meaning of green living is to live in a way that is favorable to the planet and does not harm, or use up any of its resources excessively. It shows that you care for your planet, and are willing to make an initiative to set things right. If one person starts to live in greenly, others will see the effort he is making and eventually start to follow his example. Because the condition of the planet is worsening day by day, it is important that we take an initiative right now rather than repent it later. The world is deteriorating at a rapid rate, and it is all because of us. Many people dont give enough care to what they do, and these results in a rapid use up of the planets resources. For instance, we often do not give enough care to the electricity consumption of our house. There are many ways by which you can start green living too. However, in order to actually make an impact, we people need to realize the damages that we are doing and we all need to make a collective effort towards the betterment of this planet. One person can make a difference, but one person can set an example for others to follow. Some of the tips that we can follow in order to live greenly are mentioned below. The first thing that you need to do is to limit your energy consumption. There are many ways by which you can do that. Try to avoid excessive usage of your desktop computer, because a desktop computer uses up lots of energy that could otherwise be saved. For instance, you could just start to use a laptop, and if you dont have one, it is certainly wise that you buy one for yourself so that you can limit your energy consumption. Now, as mentioned, one person cant do anything or make an impact on the planet at all. However, imagine if every person in an area started to effectively use their energy and started to limit their consumption, then what would happen? Ill tell you, the planet would slowly start to heal itself because a load would be lessened and slowly the resources that are used in generating electricity would be lessened and this could be highly beneficial because at present we use large amounts of coal and other thermal resources to facilitate our stay on this planet. However, the rapid consumption of these resources, which are non renewable would want day result in the death of one of these crucial resources. For instance, if coal becomes extinct, then a lot of activity on this planet would cease to exist and we would just be searching for alternatives that might not be found so easily. However, if we start to use non renewable energy in our homes and start to take care of our planet, we could definitely make a small impact which might enlarge and the whole world might just join the go green movement. Article#2 Green Living- Time to go green: Summary Green living is the changing of your life style to set it according to the ways of the planet. By that, I mean that we need to make our stay more favorable in this planet so that we do not harm it in any way. There are many ways to initiate green living. In order to make your life a bit better and a bit greener, you need to take certain steps so that you do not harm the resources of this planet. The first step that you can include if you wish to start green living is efficient energy consumption. Many people dont realize that they waste large amounts of energy in various unnecessary things that could otherwise be saved. Electrical energy is made by the use of thermal resources and there are very few plants that make use of non renewable resources. Hence, the more energy you waste, the more thermal resources would be used up of the planet. If all these resources get used up, this could be very harmful for the planet in a variety of ways. At present, we are rapidly using the planets resources to facilitate and make our lives better. But, if we cut down on them, we could certainly make living on this planet a bit better and much greener. You can practice a variety of small things that could certainly save you a lot of energy which could otherwise reduce the load on the planet. If you have a car that runs on diesel or petrol, it would be wise to convert it to CNG, which uses compressed natural gas that is not harmful in any way to the planet. What happen when you use petrol or diesel is that carbon monoxide and carbon dioxide are released in to the atmosphere, which harms the planets atmosphere as well as the ozone layer of the planet. We need to take care of the planet, because we have certainly used it in a very harmful way. Other things that we can do and change if we want to live greener life are that we can cut down on our energy consumption. Some of the largest amounts of energy are consumed when people leave the lights of their homes on and do not bother to turn them off. The lights just keep on using energy even though they are not being used in any way. Therefore, it is always wise and highly recommended that you shut off the lights before leaving any room so that you can save on energy. A go green movement has been initiated by the people, and it is gaining a lot of popularity as more and more people are changing their lives and living methods so that their stay on this planet becomes favorable for them as well as for the planet. You need to take care of the planet, because if we dont then there is no one else who will. We need to practice just a few things which would certainly not restrict our lives in any possible manner, but would certainly allow the planet to heal itself and become a better place for everyone to live in. Start green living, and support the planet, because it never gives up on you. Article#3 Time to Start Green Living! Summary: Our planet is slowly dying, and if we dont do anything about it soon enough, it would eventually begin to deteriorate and everything would be used. The world would become a barren place without any resources. We need to cater to the needs of our planet, and we need to change our life styles so that it becomes beneficial to the planet. We need to become much more eco friendly, so that no harm is dealt to the planet by our existence. At the moment, we are certainly not doing anything like that and in order for us to be able to know whats right and whats wrong for the planet, we really need to open our eyes and look around. Global warming is rapidly become an increasing phenomena, the glaciers are melting at a very fast rate. Do you think this is happening on its own accord? If you do, then you need to revise your thinking. The instigators of global warming are just us. We have driven the planet to the extent that it has begun to harm itself. Every day, we use up large amounts of the resources of the planet to facilitate our lives, but do we realize who is going to replenish those resources? No, we dont. All we are intent on is making life easy for ourselves. However, the time has now come for us to make a move and change our lives so that we do not pose a threat, or become a source of harm to the planet. We need to analyze and see that whatever we are doing is according the needs of the planet or not. If it isnt, then we need to change and start green living so that the planet begins to replenish its resources and becomes the beautiful place it once was. Floods, earth quakes and all natural disasters are instigated because of us if you actually look at it in a wider sense, and all we think is that the planet is hurting us. It is not in any way trying to harm us, but these are just signs of things to come if we dont take care of our beloved planet. Many people have now begun to realize the message that is being conveyed and have begun green living so that they could be free of the guild of destroying the planet. You can start green living as well, and by following some simple guidelines, you could certainly be on your way in helping the planet. It is futile to think that one person can do nothing, but you should try and set an example for others to follow. Try being a source of inspiration to others so that they also being to adopt green living as well. Simple steps such as turning off the lights or electricity when not in use could go a long way in helping the planet, and it highly recommended that we now start to utilize our energy efficiently because it is high time that we begin to listen to the pleas of the planet and try to make life better for ourselves before things get out of hand and it all becomes too late.

Free Scarlet Letter Essay: Is Hester Patterned after Anne Hutchinson? :: Scarlet Letter essays

Is The Scarlet Letter's Hester Patterned after Anne Hutchinson? Four Works Cited There are some things that could have happened to Hester Prynne in The Scarlet Letter if she had followed the footsteps of Anne Hutchinson. Anne Hutchinson believed differently from most Puritans in the 1640's. She held these beliefs with all her heart. People did not like her for that so they banished her. Hester Prynne commits adultery, but she handles it differently than Anne. She does not believe with all her heart that it was the right thing to do, so she is not punished as severely as Anne was. Hester begins by doing something against the authorities but she handles it differently than Anne did. In chapter one of The Scarlet Letter, Anne Hutchinson is considered a heroine because of her imprisonment. The chapter describes a rosebush that grew from where Anne had stepped into the prison. Rose bushes are usually associated with passion (beauty plus pain) or the church (as in Dante). Anne had a passion about her beliefs about the church and is a heroine. This rose bush grew in memory of her. Hester Prynne herself walks into this prison for almost the same reason as Anne Hutchinson. Hester had a passion symbolized by the rose also. She had a different kind of passion, though. It was not for her beliefs, but for a man of the church, Rev. Dimmesdale. This passion was in the church (the rose) but people in the church opposed this passion, just as they opposed Anne Hutchinson. The rose symbolizes what happened to both women. Right away Anne was considered a threat to authority because of her growing number of followers. People said her meetings were disorderly, but she said she was following God. Mostly because she was being more than a wife and mother and going above her place as a woman, the church banished her. The church leadership was getting upset because she had said that certain pastors were wrong and that people should live only under a "Covenant of Grace," not works, something which sounded like antinomianism. They figured that getting rid of her was the only answer. Hester had really done something wrong and deserved punishment according to the law. She had to wear a scarlet letter A. The way she handles the punishment is very different from Anne Hutchison.

Henry Ford1 Essay -- essays papers

Henry Ford1 Octavian Augustus (63 B.C.E-14 AD) is known as the first, and one of the greatest, Roman Emperors ever. Octavian enabled the long, peaceful time of the Pax Romana by changing Rome from a fragile, crumbling republican government to a mighty empire. Octavian ¹s government was strong enough to withstand weak emperors who mismanaged the Empire. His changes proved to be the cornerstone of the greatest empire the world has ever seen. During the Conflict of Orders, the lower class Romans, or plebeians, forced the upper class Romans, known as patricians, to give them more rights and liberties (Hadas 1969). The Republican government in Rome was established to satisfy the plebeians, while still leaving a majority of the control with the patricians. The government consisted of three main parts: the senate, the assemblies and the magistrates. The Senate was a group of former state officials, usually patricians, who acted as advisors, controlled public finances and handled all diplomatic dealings with other states (Hanes 1997). The assemblies were the various public meetings where citizens voted on laws and public office (Hanes 1997). Magistrates were the elected officials who put the laws into practice. The most important of these magistrates were the consuls. The two consuls each elected for one year acted as the chief executives of the state. Censors were also very important magistrates. Censors were elected every five years to take a census and record the wealth of the people. Censors also had two other very important jobs. The first was to appoint candidates for the Senate and the seco nd was to award contracts for government projects (Hanes 1997). As time passed, the Romans also began to elect other magistrates called praetors. Praetors acted as judges but could also fill in for the Consuls when they were away (Hanes 1997). The Republic first started to lose power in 133 BCE Tiberius Gracchus and his brother Gaius were the leaders of a campaign to help the landowners/soldiers of Rome (Hanes 1997). The brothers tried to redistribute the public land of Rome to small farmers. The Senate, however, feared that the brothers were trying to take power away from the government. They ordered mobs to kill the brothers and hundreds of their supporters. The Gracchi ¹s efforts were the beginning of the Roman Revolution (Hanes 1997). In 107 B.C.E, a popu... ...eum and the comedies performed at the many theatres (Hadas 1969). The Romans are attributed with the development of concrete, which enabled them to build large structures such as aqueducts. As Rome grew into the primary world leader, it ¹s Republican government was falling apart. The Senate was ineffective because it had no control of the vast armies that provided power. Conservative Romans who believed strongly in the Republic would immediately target a strong general who took sole control. Rome was in need of a solitary, powerful leader. Octavian skillfully turned himself into an emperor without suffering the fate of his great-uncle, Caesar. He controlled the army, and managed to please the masses. Once in the position of power, he changed the government not only to benefit himself, but also to benefit the Empire and ultimately the people. This structure was so strong, that it could survive through weak emperors such as Caligula and Nero and major problems like who the next emperor should be. Octavian was so influential that eventually the Romans did not care that they were no longer a Republic. They knew that with Octavian, they could become the greatest empire in the world.

American Modernism

Has modernism any relevance to the South of the world? Black people have always united together in order to create and maintain positive definitions of Blacks. The most important and common form of this racial union has been Afro-American folk culture: the musical, oral, and visual artistic expressions of Black identity that have been handed down from generation to generation. The Harlem Renaissance, whose spirit Hurston's work reflects, was a manifestation of this bonding, although it had many false revolutionaries and failed in some respects to realize its radical potential.The modernist black writers who arose in the first three decades of the twentieth century introduced a new stereotype into American literature. Zora Neale Hurston wrote as a Black woman about her own experiences and therefore, in some way, spoke to the general Black female experience in America. Hurston's novel Their Eyes Were Watching God (1937) offers an excellent source for demonstrating the modern Black fema le literary tradition. A large and chief part of Hurston's career took place during the Harlem Renaissance, which began in the twenties while she was attending Howard.Hurston's best work, especially her novel Their Eyes Were Watching God, is the product of a Black female folk aesthetic and cultural sensibility that emerged from the best revolutionary ideals of the period. It also anticipates the comparable renaissance in black women’s literature. Despite, or perhaps because of, these achievements, Hurston, like many Black women writers, has suffered â€Å"intellectual lynching† at the hands of white and Black men and white women (Brigham 23).Their Eyes Were Watching God appeared at the tail end of what is termed in American literature as the American Modernism. Roughly between 1917 – the end of World War I – and the 1930 stock market crash that marked the beginning of the Great Depression, throngs of southern African Americans migrated north -a migration that technically began as early as 1910 – primarily to the northeast for economic and social reasons, escaping more overt and often violent manifestations of tensed black-white race relations.A time when â€Å"the Negro was in vogue,† this was a time of cultural celebration of blackness – black visual arts, black music, black intellectual thought, black performing arts, and black identity (Hemenway 34). Leading voices of the Harlem Renaissance challenged black authors and artists to define African American life beyond the prescribed boundaries of stereotype and caricature, sentimentality, and social assimilation. Arguably a movement among intellectuals, the Harlem Renaissance proved spiritually and aesthetically liberating for African Americans and established global connections with an African past.Hurston's accent on rural common folk of the south both challenged and continued some of the essential tenants of the Harlem Renaissance: national and global communi ty, self-determination, and race pride. The most concentrated place of this cultural explosion was Harlem (New York). Published in 1937, Hurston most famous novel, Their Eyes Were Watching God, was not immediately famous. In fact, the novel was largely mistreated and greatly criticized by her black male contemporaries, because it allegedly presents blacks in stereotypical ways that white readers enjoyed and encouraged of black writers.This criticism was particularly harsh from those who thought that Hurston should be writing more overtly protest pieces about whites as blacks' enemies. While Hurston does not center around white people in the novel, their Jim Crow presence is apparent from the opening through the closing pages. The novel was not printed some thirty years after its initial publication. In 1971, it was reprinted but again was not printed by 1975. In 1977, Hurston's novel was on the top of reading lists among American colleges and universities and continues that even tod ay (Kenner 234).Their Eyes Were Watching God is the story of Janie, a black woman of mulatto ancestry, in search of spiritual liberation from patriarchal control. The format of the book is Janie's telling of her own story in her own voice as she remembers the details of her own life. As the narrator, Janie has an authority that even the readers cannot challenge when they want details, particularly technical details, that Janie does not remember or choose to share.While Janie's story is on many levels gender and racially related -readers never forget that Janie's grandmother was a slave or that the characters are living during Jim Crow segregation in the period of the 1930s and 1940s – much of Janie's social relations within the community of black people is gender specific. Her plot is mainly based on others' opinions of how a woman should live, what a woman and especially a woman her age should and should not be doing. Moreover, Janie in the narration is one of a person who i s able to self-define and to transcend restricted boundaries ultimately through communal storytelling rituals (Lemke 90).One of the new ways in which Hurston demonstrated alternative ways of writing is that she often collapsed the boundaries between fact and fiction. The cultural and contextual situatedness of Their Eyes Were Watching God reflect a Black woman's interpretation of social reality in the sense in which the ‘real world' is constituted, in terms of personal and cultural experience, is likely to be at variance with the interpretation of these notions by Euro-American males.Central to appreciating Zora Neale Hurston's genius, versatility, and identity politics is knowing the ways in which she frequently stepped over disciplinary boundaries in her practice of anthropology, intermixing social science with the humanities so many years in advance of what we now call postmodernist practices within anthropology. Hurston's lifelong concern with the self and its limitations (those imposed from without and from within) is, of course, the natural, perhaps even the proper subject of an autobiography. In Their Eyes Were Watching God, the narrator observes that â€Å"Pheoby [is] eager to feel and do through Janie †¦ and Janie [is] full of that oldest human longing -self-revelation† (18). Pondrom claims that the â€Å"adoption of myth as a principle of meaning and order is Hurston's most important link to modernism† (1986:201). For Pondrom, Hurston's utilization of myth links her to the modernist writers approaches of Eliot, Yeats, Joyce, Pound, and Crane. Pondrom writes that Hurston's â€Å"'mythic method' links her even more powerfully to the great female modernists, who found myth a means to affirmation of the self rather than simply a stay against disorder.†For Pondrom, Hurston takes a place among H. D. , Stein, and Wolff â€Å"in a current now [mid-1980s] being recognized as fundamental to the modernist movement† (202). Pondrom discusses overlaps between Their Eyes and Babylonian, Greek, and Egyptian mythologies. In Their Eyes Were Watching God, she writes how everyone is drawn â€Å"on stage† in the cross-gender verbal jousting: â€Å"The girls and everybody else help laugh. They know it's not courtship. It's acting-out courtship and everybody is in the play.The three girls hold the center of the stage till Daisy Blunt came walking down the street in the moonlight. † Showing the proximity of immersion and recuperation images in Hurston's diasporic underground, the African rhythm infuses the dramatic scene: â€Å"Daisy is walking a drum tune. You can almost hear it by looking at the way she walks† (1995:229). Janie's experiences in Their Eyes Were Watching God take place in relation to Hurston's deepening appreciation of the ordering potential of black culture and its West African underpinnings.Her juxtaposition of sunrise/set images and the chaotic and cosmopolitan experiences of modernity recalls accounts of Yoruba mythology cited early in the twentieth century from divination priests in Badan, Nigeria. In â€Å"The Religion of the Yoruba† Leo Frobenius records a myth invoking this structure: Long, long ago, when everything was in confusion and young and old died, Olodu-mare (God) summoned Edshu-ogbe and said: â€Å"Create order in the region of the sunrise. † To Oyako-Medyi: â€Å"Create order in the region of the sunset. † Next morning Edshu-ogbe created order in the east and in the evening Oyako-Medyi created order in the west.(1973:188–89) From the external correlatives of several scenes to her explicit invocation of Esu/Elegba, in Their Eyes Were Watching God Hurston's points of reference for Janie's emerging consciousness are markedly West African. In ways that echo the narratives recorded by Frobenius, Hurston uses sunrise and sunset descriptions as a changeable and timeless witness to chaotic developments in the plot of the novel. After Janie's initial march through Eatonville creates a swirl of envy, Phoeby enters through â€Å"the intimate gate with her heaping plate of mulatto rice† (1995:176).As Janie reflects on her experience and prepares to tell her tale, Hurston's sunset provides the backdrop: the â€Å"varicolored cloud dust that the sun had stirred up in the sky was settling by slow degrees† (178). When Janie tells Phoeby about living under Nanny's and Logan Killicks's control, Hurston uses the deepening night to underscore the danger in the tale and the telling: â€Å"the kissing darkness became a monstropolous old thing† and Janie â€Å"saw her life like a great tree with†¦Dawn and doom in the branches† (181– 82).On the morning of the conflict with Logan Killicks, the â€Å"sun from ambush was threatening the world with red daggers† (199). In the scene in which Janie awakes after having spent the night alone, wondering, while Tea Cake sp ent her money on a party, the sunrise is paranoid, â€Å"sending up spies ahead of him to mark out the road through the dark† (272). Hurston images the false calm before the final storm â€Å"even before the sun gave light dead day was creeping from bush to bush watching man† (301).The first moments of Janie's excavation are imaged as she connects the mysteries of her emerging consciousness to the eternal rhythms of movement and variability: â€Å"mostly she lived between her hat and her heels, with her emotional disturbances like shade patterns in the woods—come and gone with the sun† (236). Hurston's new technique in Their Eyes combined the excavation of consciousness with an improvised relationship to a living tradition that she encountered during her research in New Orleans and Haiti. Central to her mythic method is Hurston's brilliant use of Esu/Elegba in relation to the patterns of Janie's descent and emergence.Hurston's novel Their Eyes offers an e xcellent source for demonstrating the value of an interdisciplinary approach to Black women's culture in general and American Modernismin particular (Awkward 23). Hurston locates her fiction strongly in Black women's traditional culture as developed and displayed through music and song. In presenting Janie's story as a narrative related by herself to her best Black woman friend, Pheoby, Hurston is able to draw upon the rich oral legacy of Black female storytelling and mythmaking that has its roots in Afro-American culture.The reader who is aware of this tradition will understand the story as an overheard conversation as well as a literary text. The struggle between communal relationships and modern institutions is the core of Hurston's blues critique in Their Eyes. Janie appreciates Starks's store as a social center (Baker 98). But she is chronically inept at the tasks that relate to the business. Is Hurston implying that Janie is stupid? Unlikely. Instead, for Janie, selling things in the store distracts her from the essential rhythms of nature and the homegrown power of stories that take place on the porch.In Hurston's narration, the natural beauty of the South and the communal cool squeeze the business of the store from both sides: Every morning the world flung itself over and exposed the town to the sun. So Janie had another day. And every day had a store in it, except Sundays. The store itself was a pleasant place if only she didn't have to sell things. When people sat around on the porch and passed around the pictures of their thoughts for the others to look at and see, it was nice. (Hurston 1995:215)As the sense of social decay and the power of modern economics increases their hold on people's lives and as Janie moves outside of her middle-class economic position in Eatonville, Hurston's blues images become collective, intensify, and grapple openly with the forces of fragmentation. As a new season opens on the muck, Hurston images the economically and e xistentially threadbare workforce and the hard times: Permanent transients with no attachments and tired looking men with their families and dogs in flivvers. All night, all day, hurrying in to pick beans.Skillets, beds, patched up spare inner tubes all hanging and dangling from the ancient cars on the outside and hopeful humanity, herded and hovered on the inside, chugging on to the muck. People ugly from ignorance and broken from being poor. (282) But heeding Pound's warning to devise an adequate technique or â€Å"bear false witness, † Hurston depicts the economic ‘dehumanization’ in relation to the humanizing forces of living cultural traditions: â€Å"Blues made and used right on the spot. † On â€Å"the muck† the blues voices pierce through the â€Å"mud which is deaf and dumb† as â€Å"the jooks clanged and clamored.Pianos living three lives in one. Blues made and used right on the spot. Dancing, fighting, singing, crying, laughing, w inning, and losing every hour. † Instead of the urban realist's trope of ever-warm boardinghouse beds used three shifts per day, in Hurston's vision the keys never get cold, â€Å"pianos†¦live three lives in one. †Refusing to resolve the struggle between the â€Å"deaf mud† and â€Å"live muck, † she concludes the passage with an asymmetrical image of â€Å"rich black earth clinging to bodies and biting the skin like ants† (282).Ambiguous and improvised, impulses swirl through Hurston's modernist schema of the mud and the muck. She leaves no fixed path, no pro-forma method for descent. â€Å"Permanent transients† ride the crest of the wave where Wright's â€Å"walleyed yokels† are long since washed over and submerged by his ideological approach to the blues horrors in his memory. Instead, Hurston's excavation of â€Å"the muck† explores uncharted personal and communal territory. Janie's improvised diasporic modernist quest advances with the mantra that â€Å"new words would have to be made and said† (200, 268).At the end of Their Eyes Were Watching God Hurston describes Janie in a space of continuing diasporic modernist process. In connection to various relationships, Janie explored the patterns of inner and interpersonal experience and met many of Esu/Elegba's challenges at the communal and personal gates (Pavlic 234). She excavated new depths in her consciousness and from these depths she examined her relationship to social space with deepened insight. In death, Tea Cake becomes an ancestor and joins the patterns of Janie's consciousness.Alone in her house again, Janie opens the window to allow Tea Cake's presence to come to mind. Hurston emphasizes the modernist dimensions of ancestry. They inform the combination of communal and solitary processes and present guidance which, at best, can mitigate against the pitfalls of Afro-modernist seclusion. Hurston describes Tea Cake's ancestral presenc e now combined with her own energy (the wind) and with Janie's asymmetrical space of communal loneliness: â€Å"The wind through the open windows had broomed all the fetid feeling of absence and nothingness.She closed in and sat down. Combing road-dust out of her hair. Thinking† (1995:333). As an ancestor, Tea Cake will continue to â€Å"live† in the images of Janie's mind but, possibly in tribute to Tea Cake's performative skill, Janie's telling of the story to Phoeby demonstrates she is not isolated in Afro-modernist seclusion. Unlike Hurston's other characters, Janie is capable of articulating the depths of her experience in interpersonal terms. Hurston emphasizes how the combination of sense impression and thought prevent abstraction of the ancestors: â€Å"Of course he wasn't dead.He could never be dead until she herself had finished feeling and thinking† (333). The close of the novel seems romantic and resolved; however, Tea Cake' continued ancestral prese nce will disrupt the resolution. Esu/Elegba's role doesn't cease in death. Janie will have to pursue the patterns and enable Tea Cake to overcome the â€Å"dogged† stasis that caused his demise. Janie will have to feel the wind and share the thunder. The descendant becomes part of the redemption of the ancestor, because Esu/Elegba will return (Pavlic 243).In Their Eyes, Zora Neale Hurston, is using modernism to bring her intellectual characters out of their isolation and into contact with the needs, concerns, and traditions of black people generally. Zora Neale Hurston’s fiction, especially her novels, leads us to examine ourselves in relation to the world around us. Without exaggeration, her novels enlarge both our minds and our hearts. Hurston, however, would not make such a claim; instead, she would keep moving towards some goal to be reached, some project to be started.Her anxious restlessness about herself and her work makes her a very contemporary writer, a moder nist who tried to enlarge the very notion of what it is to be American. She wrote about traditional subjects—love and loss, displacement and home, failure and triumph—at the same time she attempted to redefine our notion of American culture. Their Eyes Were Watching God offers us the same vital contrasts and the same struggle to reconcile the harp and the sword.Works CitedAwkward, Michael, ed.

Ecosystem Management of the Laurentian Great Lakes

Management of the Laurent Great Lakes Common among models implemented in environmental management is the driver-pressure-state-response concept. This type of model uses Indicators to quantify and simplify changes occurring in natural systems. Changes in the environment, according to this model, all originate from human activity which exert pressure or stress on the system. This model attempts to solve environmental crisis by determining the human activity creating the problem and responding to change with environmental and economic policies.In the 1 9705, Environment Canada reposed a model similar to this called the state-pressure-response model, that would be used to mediate environmental issues emerging throughout the Laurent Great Lakes ecosystems. At this time, the Great Lakes faced a number of ecosystem threats stemming from the mismanagement of fisheries, Industry and farming both in Canada and in the united States. Decision makers determined that a state- pressure-response mod el would more efficient in tackling the sheer number of environmental issues faced at the time, as this type of model focuses on handling specific Issues already present.Although this model was useful In reducing pressures by enforcing stricter environmental policies, it fails to consider environmental change over time. It also fails to recognize the ecosystem as a whole as it targets each individual issue separately, giving no consideration as to how one Issue may be affecting or creating another. State-pressure-response models simply look at environmental Issues already present, there is no degree of attempting to prevent and control environmental stress.Disregarding the possibility of environment change, and ignoring basic ecosystem concepts, creates greater issues hat will only continue to grow as climate change and population growth add more stress to the lakes. Since the sass's, prevent-control models have proven to be more effective in eradicating and decreasing issues presen t in the environment. For this reason, although a state-pressure- response model was successful in diminishing major ecological concerns of the Laurent Great Lakes in the sass's, a more holistic, prevent-control model Is needed to respond to present and future ecological concerns.Current Great Lake environmental management strategies assume the lake ecosystems are static not dynamic. Over the past thirty years of management, this assumption has lead to ramifications which will only continue to worsen as climate change Is expected to pose new threats and changes to the environment. The degradation of wetlands in and around the Great Lakes is one of the ramifications of this assumption. Wetlands are the interface between terrestrial and aquatic ecosystems, therefore, management strategies must acknowledge environmental changes occurring In both ecosystems.Since the 1 9705, the Increase In alarm temperature, frequency and duration of water level changes, and the increase of inconsidera tion (Mortars, 2004). Without standardized analytical monitoring of environmental change, issues within Great Lake wetlands with only continue to emerge (Environment Canada Report, 2005). Ignorance to dynamic ecosystem concepts have also lead to the increase of reconciling pesticides in some areas (Environment Canada Report, 2005).This reinforces the need for monitoring environmental change rather than focusing only on issues present during the time the model is put into action. Looking into the future, the state-pressure-response model, which assumes lunatic stationary, will render inadequate as new issues emerge from climate change and arbitration. If governments continue to use a state-pressure-response model for the management of the lakes, many environmental changes will go undocumented and untreated, see Figure 1 in Appendix (Macdonald, 2009).Numerous studies have predicted that climate change is expected to significantly decrease water levels in lakes and streams throughout N orth America (Michele, 2007). Decreasing water levels in the Great Lakes will increase their vulnerability to toxic contaminates (Valiant, 2008). It would be greatly beneficial for environmental management models to already begin taking into account and monitoring these changes to lessen the effects of climate change. Stricter environmental policies for industries and farming practices should already be in consideration to prevent environmental concerns in the future.The environmental regulations that will need to be enforced will require much thought as well, such as debates over using a cap and trade or other emissions cutback strategies to lessen industry emissions if is required. The sooner these issues are dealt with, the more equipped decision makers will be at solving future crises. Other future concerns pertaining to the increase of arbitration around the lakes, primarily Lake Ontario, will be another negative environmental factor needing monitoring and acknowledgement of ec osystem change.With arbitration it is expected that natural vegetation will be removed and replaced with impermeable concrete surfaces which allow water to flow directly into river channels, increasing sedimentation and pollutants in runoff (Foote, 1996). Sedimentation describes the process of depositing sediment or gravel. An increase in this process will have effects felt by the entire ecosystem. Domestic water supply will be contaminated and suspended sediment will have adverse effects on the growth of aquatic plant life as it decreases the light which is able to penetrate the water (UNESCO, 2011).Fish breeding grounds and feeding zones will also be effected by an increase in suspended sediment, thus threatening fish populations. Another issue with arbitration will be the swell in atmospheric contaminates from industries, and increase in carbon dioxide from transportation use (Science Daily, 2008). Both environmental concerns will need to be monitored and regulated if governments are o establish efficient and effective environmental management strategies for the future.Before arbitration and climate change present astronomical environmental issues, governments need to consider models which recognize the environment as being in a constant state of change which will encourage critical monitoring of the lakes. Another consideration is the use of a holistic model, quite unlike the model sass's, when management decisions were being made on the Great Lakes, State of the Great Lakes Conference (SOLES) developed an indicators utilizing framework to identify major concerns of the lakes at the time, see Figure 2 in Appendix (Mitchell, 2004).The issue with using indicators to indemnify environmental problems is that it ignores the complex relationships within the ecosystem. Earlier approaches to ecosystem management examined organisms in their ecosystem context, this was later altered to the study of an entire local system with all of its biochemistry (Mitchell, 2004) . SOLES has failed to adapt the new method of ecosystem management which better explains, what and why things are happening in the ecosystem. In the early sass's, excessive recreational boating activity and shipping on the lakes lead to the introduction of a handful of invasive species.The most ecologically harmful being invasive species Addressed polymorph (zebra mussels), which has eliminated the native clam population in Lake Ontario, see Figure 3 in Appendix (Griffith, 1991). Following the state-pressure-response model, it was identified that ballast water discharge from transoceanic vessels was a major contributor to this problem. However, it was not until later that scientists began to notice the effect of this population on that of the native clam (Olden, 2008).This proves that the disconnect of species to species interaction assumed in the model will only result in unpredicted, complex ecological concerns which arise at a later time (Height et al, 2006). It is clear that an essential tool for lake management, are models that describe in detail the lake ecosystem which studies both species and human interaction and species to species interaction. Typically with indicator utilizing frameworks, like that of the state-pressure- response model, environmental management efforts are enforced only when an issues present themselves as a larger problem.In lake ecosystems, the alteration of water quality due to pollution tends to have a multiplying effect, as toxic activity accumulates over time (Ultras, 2005). Since state-pressure-response models do not exist without indicators, it is only until there is a larger scale ecosystem consequence that environmental investigation is undertaken. Once investigation begins, indemnifying the pressure or effect creating an issue is complex, and thus, additional time is taken before any action is seen to mediate the problem.Essentially, this model waits for a problem to reach crisis portions before action is taken (Berger, 9 97). In some cases, environmental responses to human activity cannot be linked to specific stresses (Berger, 1997). This is especially true when targeting point and non- point source pollution. Point and non-point source are the categories which define the main types of pollution. The first being a single identifiable localized source and the second source generally unidentifiable, such as runoff from farmland.In some areas of Lake Ontario, there are hundreds of industries and farms bordering the shoreline. Their by-products (being emissions and runoff inputs to the system are official to identify, and it becomes impossible in some cases to then identify the cause (Berger, 1997). However, the purpose of the state-pressure-response model is to recognize the source and create environmental policies to control the problem. If the source is not found, this will not happen and the problem will continue to grow. Therefore, ecosystem management models need to achieve some degree of rather than unanswered problems.Prevent-control models are needed if current and future ecological concerns of the Great Lakes are to be handled intelligently and in a time appropriate manner. Over the past twenty years, there has been a nationwide use of prevent-control models, which operate quite differently than state-pressure-response models. Prevent-control models are aimed to reduce the amount of environmental issues that arise by diligent monitoring of systems and science inspired decision making. An excellent example of this type of model is the prevention of the spread of the southern pine beetle in western Canada.In some areas, a direct control and preventative management practice requiring the removal of tree stands, known as a cut and remove, have been used (Billings et al, 2007). Although this type of method squires quite accurate and risky decision making, the difference between this model and the state-pressure-response model is astronomical in terms of maintaining ecosystem integrity. The application of a prevent and control model has been used around the Great Lakes area in efforts of counteracting the spread of non-native species from the Great Lakes into other watersheds (Cook and Williamsburg, 2001).This model is known as an on-the-ground management, meaning that there is extensive monitoring at these water bodies. This type of management is dependent upon a detailed understanding of ecosystem dynamics. Scientists first determine if a site is viable for a colony to reach, and then examines it's possible success and impact potential. Thus far, this model have been successful in controlling the spread of the hundreds of non-native species from the Great Lakes into its neighboring water systems. This model can easily be adapted into the management of the Great Lakes.Although this type of model requires an extraordinary amount of effort from the scientific community, the expertise are already there and the environmental benefits would be well worth th e effort. Human pressure on the Great Lakes is quite extensive, ND a result, lake ecosystems are unable to operate in a self-sustaining manner due to the interference or changes that exceed their capacity for self-repair (Ultras, 2005). It is essential that models in effect prevent and control environmental issues of the Great Lake to ensure irreversible damage is avoided, even if this means more funding towards monitoring and scientific expertise.To mange present and future environmental concerns of the Great Lakes, decision makers must discard the old pressure-state-response model and replace it with a holistic, prevent-control model. These types of models encourage strategic, analytical monitoring that will solve many issues in the management of the Great Lakes faced today, with the current state-pressure-response method. Monitoring ensures the documentation of ecosystem changes which will be important in the future for determining climate change effects.
