Logistics Supply Chain Management and Materials Essay Example

Logistics: Supply Chain Management and Materials Essay Logistics comprises of relatively large number of managerial activities. Discuss five of these activities and why they are important of the logistics system. Logistics is the process of planning, implementing and controlling the efficient, cost-effective flow and storage of raw materials, in-process inventory, finished goods and related information from point of origin to point of consumption for the purpose of conforming to customer requirements Logistics is responsible for the movement and storage of materials as they move through the supply chain. Depending on the circumstances, many other activities can be included in logistics. Sometimes an organization might include sales forecasting, production scheduling, customer service management, overseas liaison, third party operations, and so on. If you follow some materials moving through an organization, you can see that the following activities are normally included in logistics Procurement / purchasing: The flow of materials through an organization is usually initiated when procurement sends a purchase order to a supplier. This means that procurement finds suitable suppliers, negotiates terms and conditions, organizes delivery, arranges insurance and payment, and does everything needed to get materials into the organization. In the past, this has been seen as a largely clerical job centered on order processing. Now it is recognized as an important link with upstream activities, and is being given more attention. Warehousing: moves materials into storage, and takes care of them until they are needed.

As well as making sure that materials can be available quickly when needed, warehousing also makes sure that they have the right conditions, treatment and packaging to keep them in good condition Materials handling moves materials through the operations within an organization. It moves materials from one operation to the next, and also moves materials picked from stores to the point where they are needed. The aim of materials handling is to give efficient movements, with short journeys, using appropriate equipment, with little damage, and using special packaging and handling where needed. Inventory control: It considers the materials to store, overall investment, customer service, stock levels, order sizes, order timing and so on. Location: Some of the logistics activities can be done in different locations. Stocks of finished goods, for example, can be held at the end of production, moved to nearby warehouses, put into stores nearer to customers, passed on to be managed by other organizations, or a range of alternatives. Logistics has to find the best locations for these activities – or at least play a significant role in the decisions. It also considers related questions about the size and number of facilities. These are important decisions that affect the overall design of the supply chain

euthanasia1 essays

euthanasia1 essays The option of self-deliverance for the terminally ill person is the ultimate civil liberty. Over the past twenty years major controversy has spawned over the issue of euthanasia: a persons right to die. The American courts have been burdened with determining whether or not the Constitution gives the American people the right to allow others to take their lives, and have failed to come up with a definitive answer. There are several aspects to suicide and the law, but we are only going to discuss a few of them. First of all we will examine why anyone would want to take their own life and decipher the differences between a rational suicide and an irrational suicide. Secondly we will look at ways assistance has played in the area of suicide. Next, we'll look at what the constitution says and see if any of the states have allowed suicide. Finally, we'll study some of the cases that have been brought before the American courts. Suicide has become a big part of American society; year after year more people are taking their own lives for many different reasons. A lot of philosophers have broken down all the reasons of suicides into two different categories, rational suicide and irrational suicide. A rational suicide has been given five basic criteria that usually must be met for the person's act to be considered rational. The five criteria which a person must show for their suicide to be considered rational are, "the ability to reason, realistic world view, adequacy of information, avoidance of harm, and accordance with fundamental interests." Another opinion of rationality of suicide is, "it is the best thing for him from the point of view of his own welfare-or whether it is the best thing for someone being advised, from the point of view of that person's welfare". People have to characterize suicides because a lot of times they don't understand what that person is going through so by grouping them and plac ing crit...

Will more gun law lead to less gun violence Research Paper

Will more gun law lead to less gun violence - Research Paper Example A lower percentage of people consider protecting the legal right to own a gun as opposed to protecting people from gun associated violence. Anti-gun-control opinions are that if more states amended compulsory laws for criminals who commit crimes using guns, violence will be unaffected since such laws have been in existence but have failed to cut down crime. More laws on handguns have not had any significant effect on murder levels due to the high rate of handguns already in circulation before the laws took effect. Laws that seek to reduce guns in criminals hands might fail to reduce violence because active criminals can steal them or they can buy from the black market (Lott 34). As difficult as it may be to accept, the truth is that it is not very possible to stop a shooter no matter the number of guns present. The only way to stop or lessen gun violence is to prevent the offender from acquiring the guns first. It is not convincing to argue that guns save life, as some people will say, since with 300 million guns already circulating, no solution has been evidenced but laws discouraging acquisition of more guns may be a logical

Human Resources Management slp Essay Example | Topics and Well Written Essays - 250 words

Human Resources Management slp - Essay Example Human resource management aims to set meaningful goals and ensures that these goals are met for the future growth and success of an organization (Kaushik, 2009). Before hiring an employee, it is important for the human resource person to have a written job description on hand. A good job description includes the detailed information about the job such as the duties and responsibilities of the employee, the qualifications needed to fit in the job, and the experiences and general skills needed to be carried out by the chosen candidate. A job description is an important aspect in hiring employees since it serves as a guide for determining if an employee is well suited for the job, it ensures that the qualifications needed are matched with the potential candidate, and it serves as the foundation in constructing possible interview questions (Wolf, n.d.). Developing a good job description is a significant task for the human resource people. It serves as communication tools for the success of the organization since employees get to learn and be aware of their duties and functions. Without it, employees will tend to be confused of the workplace they are in because they do not know what is expected from them. With job descriptions, employees are provided with a clearer view of the picture about the company thus paving the way for a better communication between them and the organization. Aside from that, it also tells employees where they fit in the picture so they could perform their duties effectively (Heathfield,

Career Profile: Physical Therapy Assistant

Career Profile: Physical Therapy Assistant Health Care Career: Physical Therapy Assistant Rodny German Sotolongo Job Description Physical therapy assistants (PTAs) offer care in varying forms including teaching clients/patients exercises for purposes of mobility, coordination and strength, training patients on how to use mobility aids such as walkers, cranes or crutches (American Physical Therapy Association (APTA), 2014). They also offer massage and train patients on the same as well as use of electrotherapy and physical agents such as electrical stimulation and ultrasound. Therefore, PTAs usually offer physical therapy services while under the supervision and direction of licensed physical therapists. These services are offered to persons of different ages with medical conditions or problems or any other health-related condition, which limits their capability to move or undertake functional activities during their everyday lives (APTA, 2014). Additionally, PTAs also measure any changes in the performance of a patient due to the physical therapy that has been offered. Their work settings vary from outpatient clinics, hospitals, nursing homes, schools, home health to sports facilities and private practices. The scope of practice for the PTAs as set by the APTA consists of examining patients and their histories, testing and measuring their strength, balance, range of motion, muscle performance, coordination, posture, motor function and respiration under the supervision and direction of a licensed PT (APTA, 2014). They may also be involved in implementing the various patients’ treatment plans through the various modes of therapy to ensure continuity of care. With continuing treatment, progress is documented, and modifications may be made and implemented according to the PTs directions. The standard code of ethics for PTAs as delineated by the House of Delegates of the APTA emphasizes the special obligation of a PTA to ensure that a patient achieves greater independence, wellness and health as well as improved life quality (APTA, 2008). This is achieved by respecting patients’ rights and dignity, being compassionate and trustworthy, abiding by the law during decision-making and demonstrating integrity in their workplace. They should also enhance their competence by acquiring skills, knowledge and abilities. Education, Registration and certification A PTA education should be obtained from an accredited college or university after a two-year CAPTE-accredited associate degree. The program usually takes two years comprised of five semesters during which general education, clinical education and physical therapy courses are offered. The contents of primary physical therapy include although not limited to physiology and anatomy, biomechanics, kinesiology, exercise physiology, clinical pathology, neuroscience, behavioral sciences, ethics/values and communication (Education Portal, 2013). About 75 percent of a PTA curriculum is based on lab and classroom (didactic) study with the remaining 25 percent being dedicated for clinical education. A PTA student must also spend an average of 16 weeks on full-time experiences of clinical education. Ideally, the whole program costs about 7,816 dollars and 26,493 dollars in tuition fees in public and private institutions annually respectively according to 2008 approximations. Upon completion of the PTA program, one is awarded an associate degree in Physical Therapy Assistant. In order to practice as a PTA, one ought to be registered, certified or licensed by the particular state he/she wishes to work in, which requires passing of the National Physical Therapy Exam (NPTE) (APTA, 2014). This exam is administered by the State Boards of Physical Therapy (FSBPT). Completion of continuing education is also necessary in order to ensure that certification or licensure is maintained. Besides, PTAs are expected to be CPR certified. Employment The job outlook for this career shows a high demand for PTAs within the healthcare workforce despite the downturn in the economy. The Bureau of Labor Statistics projects that there will be a 35 percent growth in PTA employment between 2008 and 2018, which is a much faster rate of growth than any other healthcare occupation as the demand for their services grows. For example, in the month of October there were 2500 PTA jobs advertised in LinkedIn. Apparently, there are jobs that require one to have some experience while others welcome even those without experience (Education Portal, 2013). Ideally, those with experience are more preferable due to the skills, knowledge and the abilities that they possess, which at the same time warrants a higher pay compared to those without experience. The latter definitely start with a lower remuneration. Entry-level PTAs often start with a median salary of $42,100 although it may be as low as $32,420 while experienced PTAs earn a median salary of $52,160, which may rise up to about $62,360. Usually, becoming a PTA is only a beginning because there are various opportunities for career development with or without advancement in education. One can advance knowledge and skills in one field out of the many that include geriatric, pediatric, cardiopulmonary, integumentary, musculoskeletal or neuromuscular (APTA, 2014). Fellowship programs enable one to obtain skills and knowledge in a physical therapy subspecialty. They usually require at least 1000 hours of clinical experience in three years or 36 months. One can as well advance by undertaking postprofessional degrees such as postdoctoral programs or postprofessional ScD and PhD programs. Professional Activities APTA is the only professional body for physical therapists. In fact, PTA students can join and nationally the student 2014 membership charge stood at $80 with variations from state to state (APTA, 2014). Various journals have been publishing research issues related to physical therapy including the Cardiopulmonary Physical Therapy Journal located in Caroline Street of St. Louis, MO, the Journal of Physical Therapy published in Mullana-Amabala, Haryana, India and the Journal of the American Physical Therapy published in Baltimore. In most of the states, Continuing Educational Units (CEUs) are required for purposes of renewing practice licenses. CEUs are therefore required during every renewal with variations in the number of hours from state to state. For example, in the state of Alabama only 6 hours are required, 24 hours for Arkansas, none for Colorado, 20 hours for Illinois and 30 hours for Oklahoma among others (Arkansas State Board of Physical Therapy (ASBPT), 2014). These continuing education requirements can be met in various ways including taking or attending seminars or lectures related to the profession either in person or online. Courses may as well be offered by accredited professional organization on relevant topics (Federation of State Boards of Physical Therapy, 2008). Similarly, promoting a profession to outside audiences may satisfy the continuing education requirement leading to earning of a CEU. Each CEU comprises of ten hours of taking part in recognized continuing education session with qu alified sponsorship and instruction. Reflection/ Personal career Plan I believe that I can fit in this career field because of my desire to work with and assist persons with functional problems or ill health, with the aim of assisting them achieve functional abilities. At the end of the therapeutic regime, we (patient and I) will be able to see the results culminating from our hard work, a sign of valuable contribution to the recovery of an individual as well as quality of his life (APATA, 2014). This is bound to give me great satisfaction in my career as a PTA. Besides, I am a compassionate, caring and kind person with a passion of helping people. In order to be a professional PTA, my goal is to graduate as a competent entry-level PTA who functions effectively under supervision and direction of a licensed PT in the next two years. My learning objectives include acquiring knowledge, skills and abilities appropriate to enable practice as a PTA as well as to instill in me value-based behaviors required for the profession. Further, in order that I may achieve my career goals and objectives I should ensure that, I am good in mathematics and physical sciences such as Biology, Chemistry and Anatomy among others (APTA, 2011). Besides, I will learn by example from my mentors, supervisors and senior students on the best PTA practices. References American Physical Therapy Association (APTA). (2008).

Post Colonial Perception on the Grass Is Singing Essay

The Grass Is Singing, first published in 1950, was an international success. The story focuses on Mary Turner, the wife of a farmer, who is found murdered on the porch of her home. After her body is found, we are taken back to her younger days and slowly discover what happened to her. The background, location of this story is set in Southern Rhodesia (now Zimbabwe) in South Africa which has been drawn from Doris Lessing’s own childhood spent there. Her first hand knowledge of living on a farm in South Africa shines through in this book. The land, the characters, the farming are all vividly described. Both of her parents were British: her father, who had been crippled in World War I, was a clerk in the Imperial Bank of Persia; her mother had been a nurse. In 1925, lured by the promise of getting rich through maize farming, the family moved to the British colony in Southern Rhodesia (now Zimbabwe). Doris’s mother adapted to the rough life in the settlement, energetically trying to reproduce what was, in her view, a civilized, Edwardian life among savages; but her father did not, and the thousand-odd acres of bush he had bought failed to yield the promised wealth. Similar sequences are presented in the book. Doris Lessing was born Doris May Tayler in Persia (now Iran) on October 22, 1919. She is a great female British writer and in October 2007, became the eleventh woman to be awarded the Nobel Prize for literature in its 106-year history, and its oldest recipient ever. Lessing has written many novels, short stories and tales, drama, poetry and comics of which novels like The Grass Is Singing, The Golden Notebook are the most popular and her works continue to be reprinted. Lessing realized that she had quite an amazing life but didn’t know how to attack it when she started writing a book. She read a newspaper cutting about a white mistress murdered by her black cook, none knows why and he is waiting to be hanged. However, Doris knew perfectly well why he had committed this crime because of her upbringing. For example, there was a lady gossiped about in her neighborhood that she allowed her cook-boy to button up the back of her dress and brush her hair. It is appalling and awful, she says. It was a violation of the white behavior. But she didn’t behave like a white mistress. She had treated him like a friend and then started treating him like a servant. They were treated abominably. It was said that the white mistresses didn’t know how to treat their servants and obviously it was a sex thing. In African culture, for women to tell a man what to do was impossible. Yet, all these houses had men-servants and the white mistresses spoke to them in high, harassed, angry voice. They couldn’t talk to them like people. The author chooses to start this novel by the end. It begins with a brief newspaper clipping, suggesting the murder of Mary Turner under the headline ‘Murder Mystery’. However, it certainly is not a murder mystery as we are told the suspect has confessed the crime and there is no serious effort to unravel the crime. It is not who but why behind the murder. Lessing’s purpose is quite different. She wants to establish an end point in order to examine the extremely fl awed society in which it occurs. The author has given the reader a place, an event and a social problem all before her narrative begins. Lessing wrote two books, one of them at long-hand after returning home to the farm. The other one, in which she made fun of the white culture, was mannered. This helped her to write about the white culture in Southern Rhodesia in ‘The Grass Is Singing’. According to Ruth Whittaker, one of the readers of Lessing’s works, this novel is â€Å"an extraordinary first novel in its assured treatment of its unusual subject matter†¦ Doris Lessing questions the entire values of the Rhodesian white colonial society.† The novel reflects its author’s disapproval of sexual and political prejudices and colonialism in the Southern African setting through the life of Mary Turner and a fatal relationship with their black servant. On the surface, it seems a psychological and personal portrayal of a female protagonist from childhood to death but seen as a whole, it is the political exposure of the futility and fragility of the patriarchal and colonial society upon which the masculinity of imperialism has sustained itself. The whole novel can be seen as Mary’s struggle towards individuation to preserve her authenticity and sense of self but it fails because of the psychological and the political forces which furnish her little insight and threaten to crush her. I attempt to show how Lessing portrays Mary’s subjectivity as shaped and entangles within the ideological triangle of class, gender and race; and how the same sexual and ideological factors, rooted in family and culture, causes failure in Mary’s achieving her own sense of self and dooms her to death. Mary is fragmented between two contradictory statuses: on one hand she longs to be a subject of her life, to live in a way she desires, and on the other hand she unconsciously performs a role as an object of the white oppressive structure of a colonial society which extracts meaning of her personal self and imposes its values forcing, the individual to yield to the good of the collective. Mary’s subjectivity and behavioral pattern are shaped by the cross-hatched intersection of class, gender and race through the operation of sexual and political colonialism in the context of imperialism. Gender and Class: The early sketch of Mary’s characterization entails a subjectivity negotiating between gender and class positions. Mary’s early childhood is shaped under the influence of an oppressive father who wastes his money on drinks while his family lives in misery and poverty. Her mother, â€Å"a tall scrawny woman† who â€Å"made a confidante of Mary early†¦and used to cry over her sewing and Mary comforted her miserably†, is her first model of gender role: a passive and helpless woman, dominated by the overwhelming masculine patterns, nonetheless the complying of victim of poverty. Besides sharing the pains of poverty and living in â€Å"a little house that was like a small wooden box on slits† and the twelve month quarrel of her parents over money, Mary has been the witness of their sexuality and her mother’s body in the hands of a man who was simply not present for her. All her life, Mary tries to forget these memories but in fact she has just suppressed them with the fear of sexuality which comes up later nightmarishingly in her dreams. By seeing her mother as a feminine victim of a miserable marriage, she internalizes a negative image of feminity in the form of sexual repression, inheriting her mother’s arid feminism. Race and Gender: The narrator exposes that the Turners’ failure at farming and their poverty and reclusiveness have made them disliked in the district. The Turners’ primitive condition of life is irritating for other white settlers because they do not like the natives to see themselves live in the same manner as the whites, which would destroy that spirit de corps â€Å"which is the first rule of South African society†. This anxiety is more political than economic based on the opposition of white/black. ln this way, another complex clash of value system, besides gender and class, is added to the narrative structure of the novel and that is the matter of race. Colonialism is based on the white men’s spirit of venture for missionary and farm life through their settlement in the third world countries and harvesting their resources by establishing the imperial authority over the native people. The white men, by enslaving the native men on the lands they have in fact stolen fro m them and feminizing some others in their house chores, preserve their own position as masters in the center and the natives as â€Å"Others† in the margin. They use race and gender, two inseparable qualifiers, to access their privilege of power in the imperial hierarchy and legitimize their actions. Gender and race are components of this hierarchy by which the white settlers attempt to establish their own rules and security in the alien land. The binary of white/black reminds us of race difference which itself is linked and dependent on other differences, more importantly gender. White women are objectified as unattainable property of white men through stereotyping the native men as violent, savage and sexually threatening. These double strategies both take the individuality from white women and colonize them as sexual objects always in danger and in need of the heroic protection of their white men and help the white men overcome their fear and jealousy for the superior sexual potency of the black men. The dominant White culture projects â€Å"all of those qualities and characteristics which it most fears and hates within itself† on the natives which creates for the subordinate group â€Å"a wholly negative cultural identity†. Similarly Jan Mohamed notes that: â€Å"the native is cast as no more than a recipient of the negative elements of the self that the European projects onto him†. The patriarchal myth of white woman as white man‘s property and symbol of his power and the â€Å"forbidden fruit† for black man expels women from subjective roles by imposing on them the view that they are unable to handle the black laborers. Therefore the white women are convinced that they cannot share power with the white men especially in the farm life which is the current context of masculinity, tough work, action: challenge beyond domesticity. So they are confined in the domestic sphere and considered shiftless. Charlie Slatter, the most successful and powerful farmer of the district in this novel, makes a joke of it: â€Å"Needs a man to deal with niggers. Niggers don‘t understand women giving them orders. They keep their own women in their right places†. In such colonial discourse, the black natives, employed whether as domestic servants in feminine sphere or as impoverished agricultural workers, are represented as wild, violent, potential rapists, and threatening the white women who need the white men‘s protection against the natives. In this way, white patriarchy makes a heroic scenario for itself. During the first scene in which Moses touches Mary, she is alarmed at the sensation and feels certain that it is a prelude to rape. Instead, he pushes her gently on the bed, and covers her feet with her nightgown. Even in the later scene in which Moses is caught by the Englishman in a moment of scandalousl y inappropriate contact with Mary, he is caught pulling a dress over her head with â€Å"indulgent uxoriousness†. The insinuations of tenderness, indeed romance between Moses and Mary appear in this moment to offer a radical alternative to the prototypical script of rape applied to all relationships between white women and black men during the apartheid era. Any doubt as to Moses’s fundamentally violent nature is also eradicated in the final scenes in which he returns to batter Mary to death. In the sexual politics of the colonial myth, white women are victims as the native subjects are in the racial politics. A woman who is privileged racially can simultaneously experience gender limitations and class difference within her own category, like in the case of Mary Turner. Mary fails to preserve her individuality because she is not able to resist the strong master narratives of the false colonial and patriarchal myth of superiority of her culture through the discourse of gender and race which place her firmly in a predetermined position. Marginalization: Lessing has described the feelings of the characters, especially of Mary profoundly. The description of Mary, her wishes and her behavior, is done in a rather psychological way proving Mary Turner’s life tragic. She is effectively forced into marriage by the weight of social expectations and traditions. She never loves her husband, but she is, at least initially, glad to have one, as it makes her â€Å"normal†. From the moment she marries, she is engaged in a losing battle to hold on to her own identity and survive this marriage. We can distinguish Mary as a victim of marginalization. This is mainly because her needs for development are not considered by her husband and she plays no role in influencing decisions for their house. Since she is bewildered by Dick’s house which consists of a corrugated iron roof, zinc bath, skins of animals on red brick floor – all old and badly maintained, with her own saved money Mary brings flowered materials and cushions t o make curtains, a little linen, crockery and some dress lengths (61). Further she asks Dick for ceilings over corrugated iron roof but he refuses saying that it would cost too much and they may have it done next year if they do well (63). Dick is now instead investing in other things like setting up a grocery store, growing maize, harvesting beehives, pigs, turkeys, etc. that he thinks would help them grow rich less realizing his wife felt sick with the heat when she stayed in the house under the iron roof. Unfortunately, Dick keeps failing at every attempt of his to improve their condition. Mary is, all the time, counting money wasted on Dick’s various attempts at different jobs which could have improved the condition of their house. Here, Dick has never taken into account Mary’s guidance and excluded her from making or influencing his decisions before going on with these jobs. We can, hence, distinguish Mary as a victim of marginalization, the marginalized. Perhaps Mary’s tragedy is all the deeper on account of the fact that she never realizes that the native Africans who must work the farms of the white settlers are just as much tragic victims as she is. The natives are deprived of their own land and looked down with contempt. The black native men are made to serve the white colonies. Much of the discourse around the British colonies in postmodernism is centered on the exploitation of the resources and the people from the colonies, leading to a feeling of racial superiority on the part of the colonizer. This deep-seated racism is clearly evident in Doris Lessing’s The Grass is Singing as none of the white colonials are sympathetic or even see the Zimbabweans as fully human. Mary too treats all her house boys dreadfully; she despises their carelessness, their laziness, and their failure to pander adequately to her. At one moment, when she replaces her sick husband in the fields, she is thoroughly brutal with the black farm hands. However, I feel that Lessing’s novel is less concerned about showing the misery felt by the Zimbabweans for the hand they were dealt by the colonial Empire and more about showing the toll colonialism has on those who do not belong there. What Lessing is really showing is how damaging the colonial psyche can be when one is not equipped for it. One is left with a sense that when prejudice and false ideas generated by self-interest become institutionalized, they cloud the perception of people so thoroughly that even the victims are capable of victimizing others. In spite of its formulaic narrative, The Grass Is Singing has nonetheless been read as a progressive critique of â€Å"injustice, racism, and sexual hypocrisy,† in part because of its open investigation of gender and sexuality. It is through Mary’s predicaments as a woman and in particular as a member of the working class that The Grass Is Singing opens up potentially radical grounds for sympathy. At first glance, Mary’s stereotypical obsession with domesticity combined with scorn for all her black servants recalls Ronald Hyam’s caricature of white women in the colonies as â€Å"[m]oping and sickly, narrowly intolerant, vindictive to the locals, despotic and abusive to their servants†. For some, however, Mary’s plight is a more realistic and â€Å"tragic example of how hardship and isolation can destroy even the most independent of women† (Fishburn 2). Indeed, her intolerance for her black servants becomes more complex when read as a displaced resistance against the patriarchal norms of her society. Mary’s belligerence is a clear projection of her anger against an unsatisfactory marriage and the oppressive, gendered social norms that led to its existence. Dick’s attitude towards her is never hostile or abusive, but she persistently resents him for things that she knows he is not able to help, such as his string of financial failures, the unbearable poverty, and the virtual absence of any company or entertainment at the farm. Even among other white people, such as the nearby Slatter family, Mary feels too much pride and humiliation to express the full depths of her loneliness and despair. It is only in the presence of her black servants that she feels able to release the full-blown rage and intolerance that have clearly erupted from elsewhere. What really killed Mary Turner? Various critics have expressed confusion over why the dialectic must necessarily be resolved by Moses’s murder of Mary. A reviewer in The Doris Lessing Newsletter asked, â€Å"Why does Moses murder Mary?† The TLS queried, â€Å"Why does he feel he has to kill her?† and The Listener demanded, â€Å"Is this the only possible outcome?† (11) Lessing leaves Moses’s inner states shrouded in mystery: after his act of murder, â€Å"what thoughts of regret, or pity, or perhaps even wounded human affection were compounded with the satisfaction of his completed revenge, it is impossible to say† (206). Equally cryptic is the fact that Mary herself becomes complicit in her own murder, to the extent that she runs toward Moses, sure of the fact that he should kill her. This desire to die is prefaced by an unbearable, tragicomic sense of her South African history. Shortly before her death, Mary peruses volumes of books celebrating the legacy of Cecil Rhodes, and she laughs long and bitterly, thinking absent-mindedly to herself, â€Å"But the young man [Moses] would save her† (199). As she lies down to sleep on the night of the murder, she â€Å"turned her face into the darkness of the pillows, but her eyes were alive with light, and against the light she saw a dark, waiting shape. †¦ Propelled by fear, but also by knowledge, she rose out of bed, not making a sound† (203). As Mary makes her way onto the veranda, â€Å"the trees stood still and waited† until finally Moses appears, and â€Å"at the sight of him, her emotions unexpectedly shifted, to create in her an extraordinary feeling of guilt, but towards him, to whom she had been disloyal, and at the bidding of the Englishman† (204). As she opens her mouth to apologize, Moses clasps one hand over her mouth to silence her and with the other hacks her head with a blunt instrument. â€Å"And then the bush avenged itself: that was her last thought†. Mary’s cognizance of the murder as one compounded by her own guilt and by vengeance, rather than unwarranted aggression, shows a strange ability to forgive her own murderer even as he performs the act that she knows he is compelled to do. Charles Sarvan argues that Mary’s death has religious and apocalyptic overtones in that she decides â€Å"to offer herself as a sacrifice which will both atone for past crimes and hasten the coming of the new order†. Well if it came down to forensics it would be clear that the killer was Moses. But Mary Turner was long gone before Moses took a machete to her. This begs the question then of what really killed Mary Turner? In my opinion, I would argue that the real killer was the African outback. Lessing’s protagonist Mary spent her whole life in the African colony, and yet she never seems to fully belong. She spends the first half of her life in the town where she is blissfully and naively happy. Yet, even in the town Mary remains an outsider. Mary belongs to an English community and therefore must conform to English standards for women. She loves England (despite never having been there) so she performs her civic duty and jumps into a marriage with a poor farmer living deep in the African outback. A marriage in town is nothing like a marriage in the country and Mary quickly realizes it. She is uprooted from the life she immensely enjoyed in town and is planted into a decrepit farm house that is falling apart around her. The misery she feels about her living conditions is no match for the true conditions of Africa she sees for the first time. In the outback, Mary is confronted with the reality of colonialism- the natives- and she can not mentally or physically stand it. When the natives are far away working for Dick, Mary can at least barely tolerate living on the farm. However, when confronted with the natives in her home she unravels. In the African outback this idea of British civilization falls to pieces because as Sarah De Mal says in her article â€Å"Doris Lessing, Feminism, and the Representation of Zimbabwe, â€Å"the omniscient narrator describes how the main protagonist feels displaced within colonial culture since her desires and dreams are at odds with the prevailing values and rules of this culture† (De Mal 36). What Mary dreams of is a life in town, away from the natives working as a typist in an ordinary office living with other white colonists. Her reality is far removed from this as she is living with the true colonials whom she resents and despises as being the â€Å"other†. And when this â€Å"other† characterized by Moses confronts her and invades her space, her mind and her body deteriorates rapidly until she resembles merely a shell of a human being. Moses is a direct confrontation of the fantasy Mary has. She envisions herself as an English rose whose purity must not be tainted by the black man. Yet when Moses physically touches her and confronts her about her attitude towards him, Mary falls apart. By these two acts, Moses has killed her fantasy by forcing her to see him as a human being. Mary can no longer pretend she has superiority over him as a white woman. It is this realization that kills her for after she submits the Moses’ humanity she loses all sanity. Moses only finished the process by ending her physical life. I believe all in all Moses was the end of Mary. However, it was not his machete that killed her. What killed her was his which is the reality of the colony and the people who lived there. Her fantasy of being a true and righteous English woman could not hold up against the vastness of Africa and this reality broke her spirit and left her as empty as she had envisioned the African outback to be. Conclusion Mary Turner is not able to grasp her own identity because her identity is compounded by the overpowering colonial and gender narratives in which she is knit. The colonial ruling power dictates that she as an individual has to behave according to the terms imposed by her imperial identity. Even her disintegration must be silenced because it threatens the whole authority of the dominant category. Mary fails in her journey of self-quest but she is the heroine of this novel because she reverses the social, racial and cultural orders of her society though unconsciously. As in Katherine Fishburn‘s words, she is as an â€Å"accidental rebel† who at least dissolves the dichotomous orders and consequently reveals for the reader the fear and falsity of the white civilization whose indictment is the division between privileged white and the dispossessed black. (Fishburn 4) Sima Aghazadeh quotes, â€Å"by her death, Mary paves the way for the native (Africa/Moses) to take a subject ive action†. She cannot guarantee her own identity since she does not have any antidote to loneliness, poverty and gender limitations, but she foreshadows a change in Imperial attitudes. The Grass is Singing, through its circular narration from a collective perspective of Mary’s murder to an individual account of her personal life, completes an indictment of its central character’s life in the center of a closed white colonial society in southern Africa in which the linked discourses of class, race, and gender bring her into exclusion, isolation, break down, and finally to death. Mary’s failure of individuation is the failure of patriarchy and colonial culture to satisfy its female member to find fulfillment within this status quo.

Excretion and Osmoregulation Essay

In every aspect of an environment, there is a variance in the concentration of fluids present in the environment and the bodies of organisms. Osmoregulation is the regulation of water and ion concentrations in the body. Keeping this regulation precise is critical in maintaining life in a cell. Balance of water and ions is partly linked to excretion, the removal of metabolic wastes from the body. An animal’s nitrogenous wastes reflect its phylogeny and habitat Introduction: Osmoregulation is the control of water content and the concentration of salts in the body of an animal. In freshwater species osmoregulation must counteract the tendency for water to pass into the animal by osmosis. Various methods have been developed to eliminate the excess such as contractile vacuoles in protozoans and kidneys in freshwater fish. Marine vertebrates have the opposite problem; these species prevent excessive water loss and enhance the excretion of salts with short tubules. In terrestrial vertebrates the dangers of desiccation are reduced by the presence of long renal tubules that increase the reabsorption of water and salts. Moreover, an osmoregulator is referred to as the state when body fluids whose concentration is different from that of their environment, so these organisms use up a lot of energy in having to control and gain water. An osmoconformer, is when body fluids with a solute concentration is equal to that of seawater. Furthermore, this report aims to ide ntify the osmoregulator and the osmoconformer of the given species as well as to compare the specific gravity of each body fluid. Materials: As per the BI108 lab 6 handout. Method: As per the BI108 lab 6 handout. Results: Notes: The Malpighian tubules function as an excretory system and aid in osmoregulation. The tubules empty into the alimentary canal, and remove nitrogenous wastes from the insect’s body. These structures were named for an Italian anatomist named Marcello Malpighi, who discovered the tubules in the seventeenth century. In Earthworm (pheretima posthuma), the excretory system is performed by segmentally arranged, microscopic, coiled, glandular & vascular & complicated excretory tubes, called as Nephridia. The Nephridia are found in all segment of the body of earthworm except the first 2 or 3 segment. According to the position & structure of Nephridia in the body, 3 types of Nephridia are found: Septal Nephridia, Pharyngeal Nephridiam and Integumentary Nephridia. The contractile vacuole controls the amount of water in paramecium. Figure 2.0 Discussion: Figure 1.0 displays the graph of specific gravity against concentration for P. lurca and U. coarctata. From the Figure 1.0 it can be seen that P. lurca is an osmoconformer in that the body fluid is equal to the concentration of seawater. Moreover, this means that the body fluid (internal fluid) is the same concentration as that of its surroundings. On the other hand, U. coarctata is depicted in the graph as seen by the plot as an osmoregulator. So, the body fluid has a solute concentration that is different from its surroundings. These suggest and confirm that the hypothesis is correct and it is quite evident as obtained in the results and graph plotted. Similarly, the body fluids collected (extracellular fluids) are known to be denser than water itself. To add on, the dissections of the various arthropods which included the cockroach, sipunculid and also the annelid, the earthworm. Earthworms and sipunculids have structures called nephridia for excretion, whilst cockroaches have mal phigian tubules for excretion. Conclusion In conclusion, in determining which organism was the osmoregulator and  osmoconformer various other structures of numerous arthropods were also studied and analyzed. The hypotheses was indeed proven correct, as the P.lurca is the osmoconformer and U.coarctata is the osmoregulator. Osmoregulation is an important process in any animal as it assists in maintaining stable internal conditions in terms of water content and the concentration of ion soluble contents in any given body. Furthermore, as predicted by obtaining specific gravity would indeed determine the two types of osmoregulation, the organisms P.lurca and U.coarctata displayed different specific gravities that contributed in the decision. Hence, to reiterate, osmoregulation is a vital process that enables an animal’s survival as well as it contributing to the environment. Reference Martin, E. and Hine, R. (2008). Osmoregulation.
