Choosing successful industry in Saudi Arabia Assignment

Choosing successful industry in Saudi Arabia - Assignment Example The equipments extracted petroleum from within Saudi Arabia’s territory. Consequently, the Saudi Government hired employees from the other countries. The Saudi government targeted employees from countries plagued with high unemployment rates. The countries include India, and other Asian countries. As expected, huge groups of job applicants flocked into Saudi Arabia to get high paying petroleum industry jobs (Kane 2). Employees of the petroleum companies enjoy comfortable working conditions in Saudi Arabia. Saudi Arabia’s labor law article 146 and article 147 clearly requires the employer to exert extra efforts to comply with the benefits prescribed in the Saudi Arable labor law. The benefits include housing, camping, suitable healthcare facilities, and free meals. The schools are set up in order to fill the school needs of the petroleum workers and the school needs of the children. Saudi Arabia hires laborers to extract and export the Saudi Petroleum products. The oil field employees include low skilled oil labors. In addition, the Saudi Government hires engineers who will ensure smooth oil production (Kane 14). Knowledge resources. Saudi Arabia hired the expertise of engineers from other countries to help ensure smooth petroleum productions. With the expertise of the Saudi ARAMCO engineers and other labor employees, Saudi ARAMCO continues to successfully extract petroleum from within Saudi Arabia’s borders. Similarly, the expertise of the Saudi ARAMCO engineers and experienced petroleum employees contributed to the successful export of the country’s petroleum products to other countries (Wynbrandt 200). Saudi Arabia hired the petroleum research knowledge expertise of the United States firm, Standard Oil Company of California (SOCAL) to find petroleum. Consequently, the hired American company discovered oil in Saudi Arabia in 1932 in Bahrain. An entity, Iraq Petroleum Company, was formed that included

Joyce’s novel Essay Example for Free

Joyce’s novel Essay The novels Mrs. Dalloway and A Portrait of the Artist as a Young Man, written by Virginia Woolf and James Joyce respectively, are tales of persons who are challenged by the society in which they live. The roles traditionally handed down to men and women become elements of restraint for many of the characters within the stories. While convention dictates the actions that the characters should perform, the readers get the impression that the authors are in opposition to these traditions. Throughout the day spent with Mrs. Dalloway and her friends, situations arise in which characters become critical of others’ choices in a way that depicts the ideas of the narrator or author. Likewise, in the experiences of Stephen Dedalus and the other characters of Joyce’s novel, one finds that they often desire to perform actions alien to the stereotypical roles of their genders. In these novels, therefore, we find that there is no apparent desire within characters for males or females to inherit traditional gendered roles. In fact, we discover a desire to occupy a multi-gendered identity. This is important because it gestures at an identity separate from societal construction of gender. Hermione Lee relates that Virginia Woolf sought a â€Å"combination of sensibility and tenacity† in her work (xvii). This suggests a similar mixing of feminine and masculine qualities with which she imbues several of her characters in Mrs. Dalloway. Clarissa Dalloway has become a woman who ostensibly fits perfectly within the role societally configured for her gender. She is the wife of a statesman and the mother of a beautiful daughter. She throws fine parties and does the traditional female jobs of overseeing the servants, visiting the sick, and other things. Yet, Woolf appears immediately to intimate to the reader the undesirability of all this tradition to Clarissa herself, as she is seen at the outset of the novel going on an errand that should normally have been reserved for her servants. Her desire for independence is asserted in the first sentence, â€Å"Mrs. Dalloway said she would buy the flowers herself (Woolf 1). Though this rebellion is a small one and is buried in the guise of â€Å"womanly† work (going to buy flowers), the commercial aspect of it places her in the position of a business person, just as the errand frees her from the confines of the home. On this walk she thinks of Peter Walsh, a man with whom she once shared her passions for literature and freedom. Her thoughts and desires break through conventions that dictate the subservience of women. She considers marriage in a way that seems alien to its constitution, as she imbues her role in it with the type of independence that one does not usually find in the traditional view of marriage. She explains that her decision against marrying Peter was made because â€Å"In marriage a little licence, a little independence there must be between people living together day in day out in the same house; which Richard gave her, and she him† (Woolf 5). This demonstrates the extent to which she desires not to be subsumed by her husband as women often are in marriages. Continuing, she thinks, â€Å"When it came to that scene in the little garden by the fountain, she had to break with him [Peter] or they would have been destroyed, both of them ruined, she was convinced† (6). This tells what she considers her life would have been like with Peter. She seeks to add a portion of masculinity to her role by keeping something of herself and continuing to show herself to the world—a right that is usually granted without reservation to married men, but tacitly withheld from women of that time. Clarissa continues to demonstrate her inner tendencies to throw off the traditional gender role and to fulfill her political and occupational dreams. During that time in England, women’s occupations were limited to household-related chores. She considers other women who had lived non-traditional lives, and longs to have her life to live again so she could make different choices. The first of those choices would have granted her an occupation that would defy her gender. The narrator assures us that Clarissa Dalloway â€Å"would have been, like Lady Bexborough, slow and stately; rather large; interested in politics like a man; with a country house; very dignified, very sincere† (Woolf 8). The use of the phrase â€Å"like a man† is telling, in that it highlights the extent to which Mrs. Dalloway longs to be released from the confines of her sex. She wants to be endowed with the possibilities that attend a man. Also telling is her desire to be â€Å"very sincere† (8). Sincerity is not a trait that has been traditionally accorded to women, as they were encouraged to keep their thoughts to themselves (or perhaps not to have any at all). Therefore, a woman with any ideas or opinions can be considered to have been somewhat forced into insincerity by their very act of subordination to the will of their husband and in their pretence at never having anything to say beyond remarks about the running of the household. Clarissa’s urge to speak sincerely demonstrates her desire to combine traditionally masculine qualities with her feminine ones.

The Working Principle of Milling Machines

The Working Principle of Milling Machines In previous chapter, the literature review piece and objective of present work has been discussed. This chapter introduces the speculative background of response surface methodology, introduction of milling machine, cutting principal, milling cutter taxonomy, machining parameters, chip thickness formation and milling machine parameters which influence the surface roughness 2.1 BACKGROUND As an central subject in the statistical design of experiments, the Response Surface Methodology (RSM) is a collection of mathematical and statistical techniques useful for the modeling and analysis of harms in which a response of interest is influenced by several variables and the objective is to optimize this response RSM also quantifies dealings among one or more measured responses and the vital input factors. The DOE++ software was used to develop the untried plan for RSM. The same software has also used to analyze the data collected. After analyzing each response, multiple response optimization technique have performed, either by inspection of the interpretation plots, or with the graphical and arithmetic tools provided for this purpose. It has mentioned previously that RSM designs also help in quantifying the dealings between one or more measured responses and the vital input factors. In order to determine if there stay alive a relationship between the factors and the response variables investigated, the data together must be analyzed in a statistically sound manner using regression. A regression is performed in order to describe the data unruffled whereby an observed, empirical variable (response) is approximated based on a functional bond between the estimated variable, yest and one or further regress or or input variable x1, x2,†¦, xi. The least square technique is being new to fit a model equation containing the said regressors or input variables by minimizing the residual error measured by the sum of s quare deviations between the actual and the probable responses. This involves the calculation of estimates for the regression coefficients, i.e., the coefficients of the representation variables including the intercept or constant term. The calculated coefficients or the model equation need to however be tested for statistical implication. 2.2 MILLING MACHINE 2.2.1 Introduction Milling machines was first invented and developed by Eli Whitney to mass construct interchangeable musket parts. Although makeshift, these machines assisted man in maintain exactness and uniformity while duplicating parts that can not be manufactured with the use of a file. Development and improvement of the milling machine and components continuous, which resulted in the manufacturing of heavier arbors and high speed steel and carbide cutters. These components allowed the operator to remove metal more rapidly, and with more accuracy, than prior machines. Variations of milling machines were also developed to perform special milling operations. During this era, computerized machines has been developed to alleviate error and provide better. Milling are perhaps the most versatile machining operation and most of the shapes can be generated by this action. Unlike turning, shaping and drilling tools, the milling tool possesses a large number of cutting edges. Milling is the process of machining flat, curved, or asymmetrical surfaces by feeding the work piece against a rotating cutter containing a integer of cutting edges. The milling machine consists basically of a motor driven spindle, was mounts and revolves the milling cutter, and a reciprocate regulating worktable, which mounts and feeds the work piece. Milling machines are basically classified as vertical or horizontal. These machines is also classified as knee-type, ram-type, manufacturing or bed type, and planer-type. Most milling machines has self-contained exciting drive motors, coolant systems, variable spindle speeds, and power operated table feeds. Milling machines play an significant role in most machine shops, machining metals to various shapes and sizes by means of a revolving cutting tool or tools having a number of cutting edges called teeth. Such tools has known as milling cutters or mills. In order to machine numerous configurations in a milling machine, man have developed various types of milling cutters to fit the necessary requirements. Most milling cutters has made of high speed steel; some employ the utilize of carbide teeth and inserts.[20] The working principle, employed in the metal removing operation on a milling machine, is that the work has rigidly clamped on the board of the machine, or held between centers, and revolving multi-teeth cutter mounted moreover on a spindle or an arbor. The cutter revolves at a fairly high speed and the work fed leisurely past the cutter as shown in figure. The work can be fed in a vertical, longitudinal or cross direction. As the work advances, the cutter-teeth do away with the metal from the work surface to produce the desired shape. [21] Figure2.1: Working Principle of milling operation [21] 2.2.2 Milling Cutter Nomenclature Figure 2.2 shows two views of a common milling cutter with its parts and angles acknowledged. These parts and angles are common to all types of cutters in some form. The pitch refers to the angular distance between like parts on the adjoining teeth. The pitch is unwavering by the number of teeth. The tooth face is the forward facing surface of the tooth which forms the cutting edge. The cutting edge can the angle on each tooth which performs the cutting. The land is the fine surface behind the cutting edge of each tooth. The rake angle is the viewpoint formed between the face of the tooth and the centerline of the cutter. The rake angle defines the cutting edge and provides a path for chips that have cut from the work piece. The primary clearance angle is the viewpoint of the land of each tooth, measured from a line tangent to the centerline of the cutter at the cutting edge. This angle prevents every one tooth from rubbing against the work piece after it makes its cut. The secondary go-ahead angle defines the land of each tooth and provides supplementary clearance for the passage of cutting oil and the chips. Figure 2.2: The two views of a common milling cutter with its parts and angles identified. [21] The hole diameter determines the size of arbor that is essential to mount the milling cutter. A keyway was present on all arbor-swelling cutters for locking the cutter to the arbor. Plain milling cutters that has more than 3/4 inch in width can usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother draw to a close, and requires less power to operate. A plain helix-tooth milling harvester is especially desirable where an jagged surface or one with holes in it have to be milled. The teeth of milling cutters are either right-hand or left-hand, viewed from the back of the machine. Right-hand milling cutters cut when rotate clockwise; left-hand milling cutters cut when rotated counterclockwise. Saw Teeth: Saw teeth are whichever straight or helical in the smaller size of plain milling cutters, metal slitting saw milling cutters, and closing stages milling cutters. The cutting edge is usually given about 5 ° primary clearance angle. Sometimes the teeth have provided with offset nicks which shatter up the chips and make coarser feeds promising. Formed Teeth: Formed teeth can usually specially made for machining unbalanced surfaces or profiles. The possible varieties of formed-tooth milling cutters are more or less unlimited. Convex, concave, and corner-rounding milling nail clippers are of this type. Inserted Teeth: Inserted teeth had blade of high-speed steel inserted and rigidly held in a blank of machine steel or cast iron. unlike manufacturers bring into play different methods of holding the blades in place. Inserted teeth are more cost-effective and convenient for large-size cutters because of their reasonable initial cost and because worn or broken blades has be replaced more easily and at less price tag 2.2.2.1 Recommended Angles for Milling Cutter The angle between the face and the land of the cutter tooth is called lip angle (ÃŽ ²).Its value depends upon the values of rake and relief angles. A larger lip angle ensures a brawny tooth. As such, the endeavor should be to keep it as large as practicable. This is particularly chief while milling harder metals and when deeper cuts to be employed. Cutters having helical teeth are made to contains a helix angle between 10- (degree) and 50- (degree) the recommended values of principal angles are given in the table [19] Table 2.1: Recommended Angles for Milling Cutter [21] Material Recommend values in degree Rake angle(degree) Relief angles(degrees) H.S.S Tools Stellite Tools Cemented carbides Cast iron(Soft) 10-15 6-8 3-6 4-7 Cast iron(Hard) 10 3-6 0-3 4-7 Mild steel 10-15 3-6 0-(-5) 3-5 Aluminum alloys 20-30 10-15 10-20 10-15 Brasses and Bronzes 10-12 5 2-3 10-15 Mg.alloys 20-30 15-20 15-20 10-12 2.2.3 Machining Parameters 2.2.3.1 Selection of Speed The approximate standards given in may be used as a guide for electing the proper cutting speed. If the operator finds that the machine, the milling cutter, or the work piece cannot be handle suitably at these speeds, instantaneous readjustments shouldcan be made. If carbon steel cutters have used; the speed should be about one-partially the recommended speed in the table. If carbide-tipped cutters are used, the speed could be doubled. If a bountiful supply of cutting oil is theoretical to the milling cutter and the work piece, speeds can be increased 50 to 100 percent. For roughing cuts, a moderate speed and coarse feed often give best results; for last cuts, the best practice is to reverse these conditions, by means of a higher speed and lighter feed. The formula for manipulative spindle speed in revolutions per minute is as follows: Where, Spindle speed (in revolutions per minute). Cutting speed of milling cutter. Diameter of milling cutter (in inches) 2.2.3.2 Selection of Feed The rate of feed, or the speed at which the work piece pass the cutter, determines the time obligatory for cutting a job. In selecting the feed, there are several factors which should be well thought-out are as follows: Forces are exerted against the work piece, the cutter, and their property devices during the cutting process. The force exerted varies directly with the amount of metal unconcerned and can be regulated by the feed and the depth of cut. Therefore, the wrong amount of feed and depth of cut have interrelated, and in turn are dependent upon the rigidity and power of the machine. The feed and depth of cut also depend upon the type of milling cutter being used. For example, deep cuts or foul-mouthed feeds should not be attempted when using a small diameter end milling cutter, as such an attempt would spring or break the cutter. Coarse cutters with muscular cutting teeth can be fed at a faster rate because the chips may be washed out more without problems by the cutting oil. The feed of the milling machine may be selected in inches per minute or millimeters per minute the milling feed has determined by multiplying the chip size (chip per tooth) desired, the integer of teeth on the cutter, and the revolutions per minute of the cutter. Example: the formula used to hit upon the work feed in inches per minute Where Feed rate in inches per minute Chip pert tooth Number of teeth per minute of the milling cutter Figure 2.3 shows the path of feed during the cutting operation. It is usually regarded as standard practice to feed the work piece against the milling cutter. When the piece is fed aligned with the milling cutter, the teeth cut under any weighing machine on the work piece surface and any backlash in the feed screw is taken up by the weakness of cut. As an exception to this recommendation, it is advisable to feed with the milling cutter, when cutting off accumulation, or when milling comparatively deep or long slots. The direction of cutter rotation had related to the behavior in which the work piece is held. The cutter should rotate so that the piece springs away from the cutter; then there will be no predisposition for the force of the cut to loosen the work piece. No milling cutter should be rotated toward the rear as this will break the teeth. Never revolutionize feeds while the cutter is rotating. Figure2.3 Direction of Feed during machining operation [21] 2.2.4 Chip Formation in Milling Operation The scheme of chip formation during plain milling using a straight cutter is explained in figure 2.4. The cutter has a diameter and the depth of cut provided by. When milling is done straight-edge cutter, the operation is orthogonal and the kinematics of chip formation is shown in figure 2.4. Since all the cutting edges take part in machining, a study of the process is facilitated by considering the action of only a single tooth. If is the feed velocity of the table in mm/min, the effective feed per tooth in mm will be, where is the cutter rpm and is the number of teeth in cutter. The material removal rate per unit width of the job is given by. It is clearly seen from figure that the thickness of the uncut material in front of cutting edge increases gradually, reaching a maximum near the surface and again drops to zero quickly. If the feed velocity is small as compared with the circumferential velocity of the cutter, then Figure 2.4: Details of chip formation [22] Where is the angle included by the contact arc at the cutter center O in radians. Now, considering the triangle OAT, we have Hence, Neglecting the higher order terms in as it is normally very small. Using this value of in the expression of the maximum uncut thickness, we get It is obvious that when cutting with a straight cutter, there is no component of the cutting force along the straight cutter axis. The average uncut thickness can be taken as half of the maximum value. Thus, From the above equation show that when the depth of cut increases, the chip thickness increases so that increases the cutting resistance and the amplitude of vibrations. As a result, cutting temperature also rises. Therefore, it is expected that surface quality will deteriorate. When the feed rate increases, the chip thickness increases so that increases in cutting force and vibration. 2.3 SURFACE ROUGHNESS PARAMETERS Surface roughness is an chief factor when dealing with issues such as friction, lubrication, and wear. It also have a major impact on application involving thermal or electrical confrontation, fluid dynamics, noise and vibration control, dimensional tolerance, and abrasive processes, among others. The resultant roughness fashioned by a machining process can be thought of as the amalgamation of two independent quantities Ideal roughness: Ideal surface roughness was a function of feed and geometry of the tool. It represents the best promising finish which can be obtained for a given tool shape and feed. It can be achieved only if the built-up-edge, chatter and inaccuracies in the machine tool activities are eliminated completely. For a sharp tool without nose radius, the maximum height of disproportion is given by Rmax = f/(cot φ + cot ÃŽ ²) Here f is feed rate, φ is major cutting edge angle and ÃŽ ² is the inconsequential cutting edge angle. The surface roughness assessment is given by Ra = Rmax/4 Idealized model of surface roughness have been without a doubt shown in Figure 2. 5. Practical cutting tools was usually provided with a rounded corner, and figure shows the surface produced by such a tool under ideal conditions. It can be shown that the roughness assessment is personally related to the feed and corner radius by the following expression: Ra=0.0321 f 2/r Where, r is the corner radius. Figure 2.5: Idealized Model of Surface Roughness [20] Natural roughness: In practice, it is not usually possible to achieve environment such as those described above, and normally the natural surface roughness forms a outsized proportion of the actual roughness. One of the main factors causative to natural roughness is the occurrence of a built-up edge and vibration of the machine tool. Thus, superior the built up edge, the rougher would be the surface produced, and factors tending to reduce chip-tool friction and to eradicate or reduce the built-up edge would give improved surface finish. The Principal fundamentals of surfaces are as follows: Surface: The surface of an object is the boundary which separate that object from another substance. Its shape and extent has usually defined by a drawing or descriptive specifications. Profile: It is the form of any specified section through a surface. Roughness: It was defined as closely spaced, irregular deviations on a scale smaller than that of waviness. Roughness may be superimposed on waviness. Roughness is uttered in terms of its height, its width, and its distance on the surface along which it is precise Waviness: It is a recurrent deviation from a flat surface, much like impression on the surface of water. It is measured and described in terms of the freedom between adjacent crests of the waves (waviness width) and height between the crests and valleys of the impression (waviness height). Waviness can be caused by Deflections are tools, dies, or the work piece, Forces or temperature sufficient to cause warp, Un flush lubrication, Vibration Any intermittent mechanical or thermal variations in the system during Manufacturing operations. Flaws: Flaws, or defects, are random irregularities, such as scratches, crack, holes, depressions, seams, moan, or inclusions as shown in Figure 2.5 Lay: Lay or directionality is the direction of the predominant surface pattern and was usually noticeable to the naked eye. Lay direction have been shown in Figure 2.5 Figure 2.6 Surface Characteristics [20] 2. 3.1 Factors Affecting the Surface Finish Whenever two machined surfaces come in make contact with with one another the quality of the mating parts the stage an important role in the performance and wear of the mating parts. The height, shape, arrangement and track of these surface irregularity on the work piece depend upon a number of factors such as: The machining variables which affect the surface roughness has spiteful speed, feed and depth of cut. The factors of tool geometry which affect to achieve surface draw to a close are nose radius, rake angle, side cutting edge position, cutting edge Work piece and tool material combination and their mechanical property Quality and type of the machine tool new Auxiliary tooling, and lubricant second-hand Vibrations connecting the work piece, machine tool and cutting tool. 2.3.2 Factors Influencing Surface Roughness in Milling Machine The various factors which influence surface roughness of work piece in the milling machine are: Depth of cut: escalating the depth of cut increases the cutting resistance and the amplitude of vibrations. As a result, cutting temperature also rises. Therefore, it has expected that surface eminence will deteriorate. Feed: Experiments show that as feed rate increase surface roughness also increases due to the increase have cutting force and vibration. Cutting speed: It is found that an increase of cutting speed generally improves surface eminence. Engagement of the cutting tool: This factor acts in the same way as the distance downward of cut. Cutting tool wears: The irregularities of the cutting edge due to wear are reproduce on the machined surface. Apart from that, as tool wear increases, other dynamic phenomena such as unwarranted vibrations will occur, thus further deteriorating surface quality. 2.4 CONCLUDING REMARKS In this chapter, the working principal of milling machine is presented. The categorization of milling cutter with its parts and angles are presented. Machining parameters which affect the surface roughness, chip thickness formation and factors influence surface roughness in milling machine are also presented in this chapter.

The Effect of Childhood Trauma on Brain Development Essay -- Child Abu

According to the Center for Disease Control, one in every three girls and one in every five boys are sexually abused by an adult at some time during childhood. Child abuse is a vicious cycle. After a child is abused it puts a deterrent on his or her ability to succeed in life. Examples of this are adults who were abused as children are twice as likely to become abusers themselves. The majority of people in prisons were abused as children. It is no wonder why childhood trauma has such a horrible impact on a person’s personality and brain. Trauma is a serious consideration in special education. When a child is exposed to a traumatic event, such as abuse, neglect or death, it can have a lifelong effect on their mental health. Although there are numerous effects followed by childhood trauma the brain chemistry of neurotransmitters is most affected. First a person might ask what neurotransmitters are. A perfect example is a lock and a key. Neurotransmitters are keys and each one activates different receptors (locks). Today there is known to be sixty chemicals that play a role in transferring information throughout the brain and body, each of which differently effect thought, feeling, and behavior. During childhood is when a person is most impressionable. Therefore when a child has suffered any physical, sexual, or emotional abuse these instances play a major role on the connections to their brain and the way that person will react to any given situation. If a child was frequently abused their brain would continuously be in high stress alert. According to The Healing Center- On Line, studies on the physiological effects of trauma have found profound and substantial effects within multiple interconnected neurobiological syst... ...rth a lot of effort to secure the damaged connections of their brain. After the trauma the person could be haunted by nightmares or constantly bothered by their inability to recall the incident fully, due to the damaged hippocampus. Trauma is as an event more overwhelming than a person ordinarily would be expected to encounter. Therefore the individual would suffer more than a few effects including eternal change such as thought process, inability to learn properly, difficulty trusting people, difficulty in socializing, and basically an inability to live their life to the fullest without distraction. If someone knew a child in danger of abuse they should call 1800-4-A-child. The longer the child is traumatized the greater the effects will be on the chemistry of their brain, and the less chance they have of overcoming the damage in order to live a life of normalcy.

Could Eddie have succeeded without the help of Netta Essay

‘Mabo’ is an Austalian TV film which was released in 2012 which depicts the life of Eddie koiki Mabo utilizing narrative techniques and elements in which a typical drama consists of. Eddie Koiki Mabo is played by Jimi Bani and his wife Bonita/Netta Mabo was played by Deborah Mailman, the film was directed my Rachel Perkins and produced by BlackfellaFilms and the ABC. The principal story of Eddie’s journey from an exiled Murray islander to a justice fighter employed a conventional narrative flow, as well as a secondary narrative component of Eddie and Netta’s relationship, however do these two concepts of the film relate to one other. The story of Eddie Mabo’s success for the fight for freedom and justice was effectively shown over a 40 year time span yet is it clear that Eddie Koiki Mabo could not have succeeded without Netta? I am puzzled upon this question as there are many different facts and points that are indirectly raised during the film which are based on; the courage within Eddie himeself, Eddie and Netta’s children, and Eddie’s experiences before he met Netta. Throughout Australian history we have seen many acts of men and women fighting for the entitlements of the indigenous people however the most respected and recognized of these is Eddie Mabo whom of which stood up for the rights of his people from a very young age all the way to his death. Mabo battled for the right to own his land which he had inherited and with that came a directive to change the policies and laws of the government. One of the many ways he accomplishes these tasks and gains success is by courage. Eddie had courage from a young age which made him able to accomplish many objectives throughout his life time even before he met Netta and we see this just before he gets exiled from Murray Island. Killoran wanted Eddie to work on his green truck however Eddie has the courage to turn down this offer. â€Å"im not going to work as a slave†. However when Netta was involved in Eddie’s life we still see a lack of her support in some cases as she does not have the same will power and courage as Eddie. When Eddie first wanted to stand for his kind and make a change to the indigenous people, Netta did not support him from the beginning, ‘black causes now ive heard it all†. Nevertheless she may not have always agreed with Kioki but she always managed to stand by his side and support him in every way she could, e.g the marches. So with that we establish that it was Eddie’s courage who led him  to his victory however he did have support during the course of his journey. Even though MABO could be pictured as a film about a man and a woman who saw great injustice and tried to change it, the theme could also be a personal cost of a public campaign to a family who have inadequate financial means and only love and determination to get them through. Netta and Eddie are both hard working people who make an effort to try and get things done and through their pride and determination they are able to accomplish great things. Eddie fights for the rights and pride of his people while Netta stands by his side as well as constantly supporting the children by looking after them and working to provide food for them. Eddie was a focused and determined man and we see this throughout the film, one part was when Netta asked Eddie â€Å"what if you don’t win†, Eddie replies â€Å"DON’T YOU DARE!.† Perkins purposely put this scene it to show the dedication and resilience Eddie Mabo had in order to gain justice for his people, however Eddie would not be able to accomplish such tasks if it wasn’t for the strength and provisional care that Netta had for his children. Therefore without Netta’s assistance with the children Eddie couldn’t have been able to successfully focus on winning the court case f or the future of his children. â€Å"People that go to the mainland, they forget everything†. Benny Mabo said this to Eddie before he left Murray Island and it was because of this I think Eddie was so strongly willing to make a change for his people, to make the people from the mainland remember where they were from and to provide for these people with the same benefits as the white men. Eddie’s focus for the benefits of his kind was beyond the imagination of the people around him; even Netta â€Å"I’ll give you black causes† was what Netta said when Eddie was explaining about the rights for their people. Eddie’s plan from the beginning, before he met Netta was to make a change, when he was asked to work on Killorian’s green truck and he refused, and it was obvious enough that it was his experiences, with his dad, that encouraged him to have such a mentality. Evidently enough when Eddie was trying to go back to see his dad we see Netta in the cubical looking upon Eddie as he was frustrated because he was unable to see his dad. This idea of Eddie being alone symbolized that he must accomplish his objectives alone, â€Å"IM going to make history†(dining room scene), as he began his journey alone and stood alone at the pier when wanting to go back to Murray Island. Eddie’s idea of change originated from  the teachings of his father, as we see the constant flashbacks throughout the film, not because of the involvement with Netta. Rachel Perkins successfully show the story of Eddie Mabo’s success for the fight for freedom and justice was effectively shown over a 40 year time span yet is it clear that Eddie Koiki Mabo could not have succeeded without Netta? This question is highly acceptable upon both sides and views of the argument, based on; the courage within Eddie himeself, Eddie and Netta’s children, and Eddie’s experiences before he met Netta.

Mc Donalds Business Report Essays - Food And Drink, Fast Food

Mc Donalds Business Report Essays - Food And Drink, Fast Food Mc Donalds Business Report McDonald's INTRODUCTION: McDonald's Corporation is the world's leading food service organization. The corporation started out as a small drive-through in 1948 by two brothers, Dick and Mac McDonald. Raymond Albert Kroc, a salesman, saw a great opportunity in this market and advised Dick and Mac to expand their operation and open new restaurants. In 1961 Kroc bought out the McDonald brothers. By 1967 McDonalds expanded its operations to countries outside the U.S.A. This unyielding expansion led the Corporation to open 23,000 McDonald's restaurants in 110 countries in 1994, producing $3.4 bn in annual revenues. In addition, McDonald's opens a new restaurant every three hours. Also, McDonald's has twice the market share of its closest U.S. competitor, Burger King, representing 7% of total U.S. eating-out sales. Similarly, McDonald's serves about 1% of the world's population on any given day through its 23,000 restaurants internationally. Big Mac, the world's most sold hamburger was developed by Jim Delligutti in 1967 to feed construction workers. 'Big Mac' is the biggest attraction and backbone of the corporation. Moreover, McDonald's maintains its competitive advantage by constantly creating new items to add onto its menu. This shows us that McDonald's practices an analyzer type of strategy, introducing new items and defending its existing ones. McDONALD'S MISSION AND VISION: We serve people with good quality food, fast and at low cost. McDonald's vision is to dominate the global food-service industry. Global dominance means setting the performance standard for customer satisfaction and increases market share and profitability through successfully implementing our convenience, value and execution strategies. THESIS STATEMENT: To have a clear picture of McDonald's corporation we need to look at its Task Environment, which includes its: .Customers .Competitors .Strategic Allies .Suppliers .Regulators We shall also explore McDonald's Workforce Diversity and its Total Quality Management. CUSTOMERS: Customers are those who pay money to acquire an organization's goods or services. For many years McDonald's mostly targeted the young people, however this has changed in this decade; McDonald's has turned towards a more general market. By doing this McDonald's concentrates on the family, targeting a diverse market which includes consumers ranging from children to elderly people, using products such as the happy Meal for children and Egg McMuffin for the elderly. McDonald's also realized the changing world we live in and the need for healthier food, since there is an ever changing demographic group, who demand fast, top quality food that is low in calories. McDonald's responded to this opportunity and introduced a new and innovative product. This new product was a regular hamburger that tasted like the real thing but was made of plant material like Soya beans. This same product also targets another demographic group, vegetarians. McDonald's mostly uses psychographic segmentation targeting the working and middle classes. These are the people that are more susceptible to enter a fast food restaurant, since these are the people that lead a fast moving life and thus require a fast meal. In brief McDonald's customers are of all classes, but largely working and middle classes, and people of all ages. COMPETITORS: A competitor is an organization that competes with other organizations for

Free Essays on Andrew Jackson

Andrew Jackson Two Irish folk named Andrew and Elizabeth Jackson came to America in 1867, settling in the Waxhaw area of the North/South Carolina border. Elizabeth wouldn’t know that her child would bring fame, fortune, and great leadership to America. On March 15, 1867, their son was born; Andrew â€Å"Old Hickory† Jackson. Andrew Sr. died and left Elizabeth a widow with three young boys in poverty. As Andrew grew up, his two brothers joined the militia where they died of disease as well did his mother. He was orphaned at the age of fourteen and gradually picked up bad habits like drinking, gambling, fighting, etc. Throughout all of his traumatic past, there seemed like there was no hope until he reached the age of seventeen. Andrew went into studying law with a North Carolina lawyer and migrated west to Nashville. After Andrew moved, he became a public prosecutor and married Rachel Donelson, a wealthy family member. Andrew afterwards acquired land and slaves. He was elected to congress in 1796 after Tennessee departed from North Carolina and became the union’s sixteenth state. The following year the legislature elected Andrew as a U.S. senator which he held for only one session before resigning. After he resigned, he went back home and served as a judge on the Tennessee Supreme Court for six years. Jackson’s military career began in the Revolution. In 1802, he was elected major general of the Tennessee militia. Ten years later, he was elected major general of the U.S. forces by Wille Blount, the Tennessee governor. In 1814, Jackson suffered numerous detrimental campaigns against the Native Americans in the Creek War and was promoted to major general in the regular army. The Creek War began on August 30 of 1813 by the slaying of 250 Alabama settlers in a brutal onslaught by an Indian tribe called the Red Sticks. As a result of the attack, Jackson and 2500 manned forces were deployed to stop and punish the Indians. Jackson ... Free Essays on Andrew Jackson Free Essays on Andrew Jackson Andrew Jackson EARLY LIFE Andrew Jackson was born to poor Irish immigrants on March 15, 1767, near Camden, South Carolina. His parents, Andrew and Elizabeth, and two older brothers, Hugh and Robert, had emigrated from northern Ireland in 1765. Jackson was named after his father who had died shortly before he was born and he spent his early life in the Waxhaw settlement located near the North and South Carolina border. His mother had hopes of him becoming a Presbyterian minister, but young Jackson’s pranks, cursing, and fighting quickly erased those hopes. From 1778 to 1781, the American Revolutionary War had a devastating impact on Jackson’s life. When he was thirteen, Jackson and his brothers joined the patriotic cause to fight the British. His oldest brother Hugh died of heat stroke following the Battle of Stono Ferry in 1779. In 1781, Jackson and his brother Robert were captured and both contracted smallpox in prison. Jackson’s mother arranged for their release in a prisoner exchange. Although Jackson eventually recovered, his brother died of smallpox. Jackson and his mother traveled to Charleston to aid in the war effort and she contracted cholera and died. By war’s end, Jackson was an orphan. He resided with members of his mother’s family, but soon went to Charleston and worked as a school teacher for a short period of time. Jackson was known for his fierytemper, fearlessness, playful personality, and daring spirit. At age seventeen, he moved to Salisbury, North Carolina, where he studied law. In 1787, after three years of studying, Jackson received his license to practice law in North Carolina. To supplement his income, he also worked in small-town general stores. While living in North Carolina, Jackson gained a reputation for being charismatic, wild, and ambitious. He loved to dance, entertain, gamble, and spent much of his free time with friends in taverns. Soon after... Free Essays on Andrew Jackson Andrew Jackson Two Irish folk named Andrew and Elizabeth Jackson came to America in 1867, settling in the Waxhaw area of the North/South Carolina border.

Free Essays on Andrew Jackson Andrew Jackson became the nation’s seventh president in 1829. He made significant changes in American politics at that time. He was very popular with the people because of the fact that he was a hero of the War of 1812. He had also served in the senate and was a tough man who had manifested the spirit of the frontier. One change Jackson brought about was the steadily increasing power of the west. He happened to be the first president to come from the west of the Appalachians. Jackson was also the start of a new era of democracy in American politics. He didn’t belong to a party but rather had much popular support. Jackson supporters were poor and relatively new voters. Unlike other races (besides that of 1824) all white men were allowed to vote rather than just white male property owners. The election of Jackson in 1828 tripled the votes cast from 356,000 in 1824 to 1.1 million in 1828. Most of those new voters gave their votes to the man of the people, Jackson. The power of the voters was evident. Jackson had won 178 electoral votes to Adam’s 83. The election also stirred another change; the revival of the two-party system. This race gave voters a choice between two candidates with sharply differing views. An opposition party had arisen and with it came many conflicts but the new party would also strengthen the democratic process by stirring debates on key issues and giving two different views on matters. Many newly elected officials elected to office used a practice called patronage. Jackson made the practice official by dismissing more than 200 presidential employees and about 2,000 other officeholders. They were replaced with 2,000 Jacksonian Democrats. The term spoils system was soon derived for the patronage system under Jackson. The spoils or pillage (jobs of previous appointees and officeholders) were taken from a defeated enemy. Jackson stated, in defense of the spoils system that any intellige...

Different Types Of Sharks Essays - Carcharhinidae, Sharks

Different Types Of Sharks Essays - Carcharhinidae, Sharks Different Types Of Sharks INTRODUCTION Although sharks belong to the class Chondrichtyes, there are many different types. Sharks arose about 350 million years ago and have remained virtually unchanged for the past 70 million years and still comprise a dominant group. It is thought that sharks almost certainly evolved from placoderms, a group of primitive jawed fishes. It took a long series of successful and unsuccessful mutations with fin, jaw positions etc to give us all the different designs of sharks around today. When asked to draw a shark, most people would draw a shape along the lines of the whaler shark family, tigers or a mackeral shark such as a porbeagle. However many people do not realize the sheer diversity in the shape of sharks, or that rays are really sharks. Seldom does such an animal inspire such a variety of emotions reflecting a mixture of fascination, awe and fear. Sharks have occasionally exacted a terrible price from humans who have trespassed on their territory. No better understood than the ocean that they inhabit, these creatures should be regarded in the same way as lions, tigers, and bears: as dangerous, predatory but nonetheless magnificent animals. Different Types of Sharks Living sharks are divided into eight major orders, each easily recognizable by certain external characteristics. Each order contains one or more smaller groups, or families. In all there are 30 families of sharks and they contain the 350 or more different kinds or species of sharks. The eight major orders of sharks include the Squantiformes, Pristiophormes, Squaliformes, Hexanchiformes, Carcharhiniformes, Lamniformes, Orectolobiformes, and the Heterodotiformes. The orders have distinguishing characteristics that fit in each. The Squantiformes normally have flat bodies that are ray-like with mottled dorsal surfaces. These sharks have a short terminal mouth, which is armed with small impaling teeth. They also have a caudal fin, which has a lower lobe that is longer than the upper lobe. Their pectoral fins extend forward over the ventrally directed gills. The Pristiophormes have more of an elongated snout, which is saw-like and edged with slender, needle-sharp lateral teeth. They have two dorsal fins and no anal fin. They use short transverse mouths and small cuspidate holding teeth in both jaws. Squaliformes have no anal fin as well, but their snout is not elongated, but is somewhat long. Many have powerful cutting teeth in both jaws. In some species these razor sharp teeth are in the lower jaw only and the upper teeth serve to hold the food. Hexanchiformes have six or seven gill slits. They are sharks with a single spineless dorsal fin, and an anal fin. The typical Carcharhiniforme has an elongated snout, a long mouth that reaches behind the eyes, an anal fin and two spineless dorsal fins. The eyes have movable, nictitating lower eyelids worked by unique muscles. Teeth vary from small and cuspidate or flattened to large and bladelike. Carcharhiniformes have no enlarged rear crushing teeth. Along with this they have a spiral scroll intestinal valve. A Lamniforme shark has an elongated snout. Most have long mouths that reach behind the eyes, an anal fin and two spineless dorsal fins. They also have a ring intestinal valve. The Orectolobiformes have pig-like snouts and short mouths that in most species are connected to the nostrils by grooves. There is an anal fin but no fin spines on the two dorsal fins. They have uniquely formed barbells at the inside edges of the nostrils. Heterodotiformes are the only living shark that combines fin spines on their two dorsal fins and anal fin. They only have five-gill slits. In each order there are specific types of sharks. Each shark belongs to a family with different species. The Angel shark (Squantiforme) is just one of the many. It has a single family of about thirteen species. They are all ovoviviparous livebearers and most do not exceed 1.5 meters. Saw sharks (Pristiophoriformes) are harmless bottom sharks. They are also a single family but with five species. They are also ovoviviparous livebearers. Four sharks that belong to the order Sqauliforme are the Bramble, Dogfish, and Rough sharks. They have three families with eighty-two species. They too, are ovoviviparous livebearers. They have more cylindrical bodies. Frilled sharks, Six, and Seven gill sharks (Hexanchiformes) have two

Music Purchase Behaviors Essay Example | Topics and Well Written Essays - 1500 words

Music Purchase Behaviors - Essay Example Music has long been an established mass media business based on consumer trends and preferences. Understanding those preferences will allow the marketing research team to define the empirical culture of music buyer's. Hip-hop, for example, holds opportunities for mainstream advertising especially, "Hip hop has become so mainstream that many marketers feel they get it. But, it is those companies that need to "check themselves before they wreck themselves." Hip hop is not static nor is it monolithic. Hip-hop culture is constantly evolving and extremely diverse" (Wells 2006). Furthermore, marketing and advertising based on the previously important and coveted 'radio-play' may not hold all the answers to music marketing "reports of terrestrial radio's impending death appear to be exaggerated. Fifty-five percent of those polled said that they still turn to the FM dial to find new music. But that is likely to change as digital music spreads — only thirty-eight percent of downloader' s look to radio for new tunes"

Economic globalization reduces the possibility of conflict Essay

Economic globalization reduces the possibility of conflict - Essay Example From a critical point of view, when countries learn to depend on each other, they form long lasting relationships as the feel that they need each other for survival. On this note, they are committed to maintain harmony to ensure that this interdependence works out for all of them and that each country can uplift their economy. Since countries are unique entities with different resources, it is true that globalizing the economy will ensure that conflicts are reduced and each country can depend on its allies. On this ground, it is clear that the harmony that the world enjoys today is a result of health relationships that have resulted from the formation of a global economy. The end of the 20th century and the 21st century is a time when the world has experience harmony as a result of reduced conflict. The world economy structure has changed due to the formation of a global market where countries are free to venture. Unlike in the post war period, countries are free to invest across the world due to reduced barriers of foreign business entrants. As Barbie (1996) points out, there has been great economic integration to the extent that it is impossible to tell where a product was manufactured. Barbie gives the example of goods that are â€Å"made in China† but have actually been produced through operation integration. Countries have come together to venture in common markets to the extent of collaboratively producing one product. As countries exhaust their domestic markets, they are free to invest in foreign markets in the onset of market liberalization. In the 21st century business organizations have ventured in international markets to increase t heir profits by investing in unexploited markets. This kind of economic integration has resulted into reduced rivalry as countries learn that the domestic market is not enough for economic development. As a result, the new century has seen the number inter country wars reduced due to the economic cohesion that

Research Problem of Coca-Cola Case Study Example | Topics and Well Written Essays - 1000 words - 1

Research Problem of Coca-Cola - Case Study Example Therefore, this called for a change of strategies by Coca-Cola and their option was to introduce a new product that offered the same feature like their competitors. In this case, they had to conduct a research in order to introduce a new product to market. Â  After the investigation, they identified that Pepsi was offering a product that had a sweeter taste and this contributed to a growth in the preference resulting in increased market share. Coca-Cola commenced a research project, whereby they spent two years and $4million prior to settling on a new formula. They conducted 200, 000 taste test on the final formula and a blind test, whose results were sixty percent of the consumers choosing the new formula over the old one. In fact, fifty-two percent of the customers choose it over Pepsi, and this was an indication that new coke would assist in dealing with the problem of losing the market share to Pepsi. Â  There was a narrow definition of the research problem by Coca-Cola, given that the research emphasized on the taste only and ignored the feelings of the customers in relation to replacing the old Coke with a New Coke. Therefore, Coca-Cola Company should have investigated on other intangibles such as the band name, history, packaging, cultural heritage, and reputation. In fact, they forgot that the symbolic meaning of coke was more important to the consumers than the taste. Moreover, Coca-Cola should have focused on the conducting a marketing research considering these emotions. Furthermore, there was a poor judgment during interpretation of research planning strategies by the managers. Â  

Interview Questions Essay Example | Topics and Well Written Essays - 750 words

Interview Questions - Essay Example I would be looking into valid reasons and even pry on the previous academic records. If previous records indicate that the standard GPA was met (which I assume it was since the student is already a sophomore student and would not have been admitted to the course due to the minimum admission criterion), I would determine the reasons for the apparent decline. Could there be stressful and challenging external factors that could have contributed to the decline other than failure to study or deliberate non- submission of academic requirements? If there are, I would seek the student to submit proof of circumstances that might have contributed to the lack of focus on educational pursuit. Likewise, I would like to know if the student is determined and committed to graduate from the course. If not, I would immediately advise that the student be taken out from the program. If, there is evidence that the student tried hard to attain the standard GPA, but mitigating circumstances that could not have been avoided, I could give the student another chance – provided that the standard GPA would be met next semester. Finally, I would determine what strategies were planned by the student to improve the academic performance in the coming semesters. 2. What role does technology and social media (such as Facebook, instant messaging, video conferencing, blogging, Twitter, podcasts, etc.) have in the adviser/student relationship? How do they help? How do they hinder? In contemporary generation’s academic pursuit, the role that technology and social media plays in the adviser/student relationship is crucial and significant. One strongly believes that both students and educators maintain registered accounts with social networking sites that could be utilized to exchange information, relay academic messages, and be used as a medium for enhancing much needed information, as required from the course. As proven from the research conducted by Lin (2011) and published in the Jo urnal of Online Learning and Teaching, the findings revealed that â€Å"integration of online activities into traditional teacher education courses can shift some of the power, authority, and control from the instructor to the learner while providing the interaction and connection that are central and valuable to traditional classrooms† (p. 99). Thus, technological applications and social media help in fostering a more conducive learning environment by encouraging active interaction and participation of course modules. As emphasized, â€Å"it used technology to increase interaction among students, increase engagement in learning and established a learning community outside of the classroom, while allowing individual contributions to be identified and evaluated† (Lin, 2011, p. 106). On the other hand, these networking sites could also hinder effective academic performance if the adviser or educator fails to provide a more vigilance and pro-active oversight to govern and validate student’s performance. This simply means that educators must have ways and means to discern that it is the students themselves who responded to the required academic requirements. 3. The media landscape is evolving. How do you approach advising a current student to prepare for a job market that is ever changing? As the media landscape was acknowledged to be continually evolving, students who prepare to hunt for job opportunities must exercise

None - Assignment Example If any of the students is found hurting emotionally for several days because of a failure, a rejection, a bad mood, or any other reason, it means the student has got a psychological wound. And, it needs to be treated with emotional-first-aid techniques. Therefore, the method for emotional first aid is required to improve the teaching practices because it helps to analyze and treat the emotional pain of the students (Lunenburg & Ornstein, 2011). 3. Being an educator it is necessary that before giving emotional first aid to the students the technique should be practices for personal emotional hygiene. In order to improve the personal emotional hygiene, few steps can be taken for the emotional hygiene. These steps include: Attention towards the emotional pain, protection of the self-esteem, control over the negative thoughts, control over emotional bleeding, and knowledge about the impacts of physical wounds. Teaching also gives experience and ideas about the wide range of emotions and emotional pain. Thus, after personal emotional hygiene the steps should be practiced during teaching (Blase & Kirby, 1992). 1. A health-care professional Nadine Burke Harris stated childhood trauma and its impacts on life in long term. Herein, it should be noted that this is an important thing that must be considered by an early childhood educator. The reason is that the incidents that happen with any child in early age leave its footprints on the mind. These impacts are stronger than it could be in any age group. It is the reason due to which it is suggested that the childhood traumas should be handled and taken seriously to avoid the possible attitude problems in children. These childhood traumas impact on the cognitive approach to the children and it changes the behavior of the children. Therefore, the idealistic approach or practice for an early childhood educator is that these children who have been through any

An investigation of the support newly qualified radiographers receive Essay

An investigation of the support newly qualified radiographers receive towards developing their CPD (continue professional development) in united kingdom - Essay Example While the desire and opportunity to develop learning and reflection from the practice take a back seat (Brown 2009). SOR (Society of Radiographers) clearly found that unlike CPD resource support to other health care workers, radiographers are not placed well. Hence post registration skill development has remained little, if any. But the role extension has been taken as common practice during the duration of service so radiographers too have moved up to clinical practice and higher academics and research (Henwood 2003). However, if the radiographers plan to remain in practice, then also CPD helps in achieving supervisory and/or specialist positions. Achieving higher positions is a biggest incentive for a radiographer to undertake CPD even if he has to arrange for it on his own. Due to work pressures however employers are reluctant to release staff for CPD (Brown, 2009). The radiography is considered a career with monotony and routine work, heavy workload with little credit and family consideration by the school students (Coombs et al, 2003). Moreover lack of clarity of a programme makes radiographe r reluctant to go for it. The present article attempts to critically evaluate the various CPD options available to radiographers for job satisfaction and career advancement. It has been clearly indicated by Department of Health (as cited in O'Donoghue, 2006, p92) allied health services personnel must regularly update their knowledge through CPD. Its working together-learning together document emphasised the need stating it necessary for improved patient care and better opportunities for professionals. The e-earning is preferred by higher education funding in UK since professionals can update knowledge without loss of time. The Society of Radiographers (SOR) has emphasised need for CPD, despite initial apprehension about its effectiveness. It has stated that radiographers "must maintain and strive to improve their professional knowledge and competence'... Every patient is entitled to be cared for by radiographers with relevant and up-to-date skills and expertise. Therefore all radiographers must undertake lifelong learning and will keep a record of their ongoing development activities... The Society and college considers that CPD, lifelong learning, peri odic appraisal and revalidation must be compulsory to ensure and maintain competence, as well as enabling radiographers to gain knowledge and competencies outside their scope of practice" (SOR 2009, p1). The radiographers' professional and other bodies thought of CPD when some efforts by NHS to appoint non-medical consultants did not succeed fully as there was lack of appropriately qualified and experienced consultants. Moreover, the clinical and educational pathways to prepare potential consultants are also ill defined (Hardy & Snaith, 2007). The study necessitates upgrading the basic training in radiography to make subsequent CPD effective. Cherry and Duxbury (1998) have felt that in spite of training at higher educational institutions i.e universities, the radiographers are equipped only with basic competences. The half life of this knowledge is only 2-5 years so it can not provide the competency for life time. It is more so in these times considering the rapid technology changes.

Amyotrophic Lateral Sclerosis (ALS): Improving Treatments

Amyotrophic Lateral Sclerosis (ALS): Improving Treatments Summary ALS is a progressive, fatal motoneurone disease, ultimately leading to paralysis and respiratory failure within 3-5 years. There is currently only one FDA-approved drug, Riluzole, but its lack of disease prolongation combined with the aggressive disease nature means identifying new treatments is essential. This review highlights 3 of the most current and promising research areas. Recent Phase 1 Clinical trials have proven safety of stem cell (SC) implantation in humans. Parallel rodent SC models show positive results in both decelerating disease progression and promoting anti-inflammatory neuronal protection. Supplementary use of growth factors also shows potential regarding motoneurone survival and dendrite length in cultures, and survival rates in mouse models. Knockout of glial xC- glutamate anti-porter significantly reduces excessive glutamate levels in neurones by 70%, compared to xC- +/+ microglia. Knockout also reduces levels of pro-inflammatory markers. These findings highlight vital role of xC- system in reducing neuronal glutamate excitotoxicity. Antisense technologies effectively reduced SOD1 protein and mRNA levels, consistent in CSF and brain of SOD1 rodent cortices. This supports SOD1 as a good biomarker for future antisense studies. Overall, there is promising research being conducted. However improvements in clinical trial techniques must be addressed in order to reliably compare findings from future studies, and allow identification of a cure in the future. Summary word count: 213 Introduction Also known as ‘Lou Gehrig’s Disease’, Amyotrophic Lateral Sclerosis (ALS) involves loss of upper and lower motoneurones from the brainstem and spinal cord. Symptoms progress from difficulty in limb movement to paralysis, and finally respiratory failure, the biggest cause of death in ALS. With a prevalence of approx. 2:100,000 and average onset age of 55 years, death usually occurs 3-5 years after onset. Although first identified in 1869 by Jean-Martin Charcot, there remain no conclusive disease causes. The disease is classified into 2 types: Familial ALS (fALS), the inherited form, is responsible for approx. 10% of all cases. There are a handful of genetic mutations linked to fALS, including: C90RF72, TDP-43, FUS, Ubiquilin-2, and currently most relevant in disease-models, Cu2+/Zn2+ Superoxide Dismutase (SOD1). Sporadic (sALS) form comprises the majority of cases, and this unknown nature of the disease makes targeted treatments challenging. Riluzole is currently the only FDA approved treatment for ALS, increasing life expectancy by 2 months. In 2011, ‘Nuedexta’ was also approved as a treatment for pseudobulbar effects in ND diseases. Patients must otherwise rely on palliative care to improve quality of life. This review will focus on the most current and widely researched areas. Proposed mechanisms of disease are beyond the scope of this review, but can be found in a review by Cleveland and Rothstein (2001). Stem Cell Therapy Due to its infamous potential, stem cell (SC) therapy is perhaps the most widely researched treatment area. SC therapy aims to improve symptoms rather than cure the disease, by either targeting re-growth of neurones or promoting their survival. Here we will focus on clinical and pre-clinical SC trials in the last 5 years. Direct neuronal replacement One proposed treatment method is to replace dying motoneurones with SCs. Recent Phase 1 Clinical Trials by Glass et al., (2012) and Feldman et al., (2014) studied the safety of lumbar and cervical SC injections, respectively. Both trials found good patient tolerance and sufficient safety to continue with future trials. Feldman et al. also used histochemical analysis to address concerns over unpredictable SC migration, by highlighting successfully transplanted SCs in spinal cord slices, Figure 1. Figure 1. B) Cross-section of spinal cord highlighting non-native cells C) Close-up shows morphology of cells consistent with pre-implanted SCs, indicative of successful transplantation into spinal cord. [Adapted from Feldman et al., 2014] Despite multiple limitations to the experimental technique, such as absence of a control group, results indicated early SC transplantation has a good chance of slowing disease progression in ALS patients, as 50% of patients showed improvement in 6-15 month post-trial check-ups. The corresponding Phase II Trial commenced in September 2013, and is due for completion this month. Figure 2 shows a previous study by Karussis et al., (2010) where SC injection leads to a significant increase in immune-regulatory cells (CD4+/CD25+) and an overall decreased immune response. Figure 2. Levels of neuronal cell inflammatory markers following injection of SCs [Adapted from Karussis et al., 2014] Reduction in immune response over 24hrs was in fact greater than seen in immunomodulatory medicines, suggesting additional mode of action for SC therapy. Neuronal survival via growth factor delivery Unsuccessful trials in the late 1990s to treat ALS with growth factors (GFs) prompted further studies into appropriate CNS targeting. Development of the SOD1-mutant rat model allowed Suzuki et al., in 2008, to address these delivery issues in a study using SCs as GF vectors. They found GF delivery to mid-stage SOD1 rodents showed increased neuromuscular connections, and a lifespan increase of 28 days, possibly due to reduced neuronal loss. Viral vectors for trophic factors (TFs) provide an alternative delivery route, and in 2010, Dodge et al., carried out mouse embryonic-SC motoneurone studies in which expression of TFs IGF-1 and VEGF-165 using viral vector, AAV4, allowed successful delivery of TFs to entirety of CNS. This slowed MN decline and increased mouse survival. Figure 3 shows initial culture studies using mouse-derived embryonic motoneurone SCs, showing clear protective action on neurones. Figure 3. A) 70% of motoneurones died in control, GFP-CM, compared to high survival with IGF-1-CM/VEGF-CM. B,C) IGF-1-CM/VEGF-CM treated motoneurones showed increased neurite length and survival rates compared to control. [Image from Dodge et al., 2010] Subsequent mouse studies showed increased survival and decelerated reduction in hindlimb grip-strength and stamina on the rotarod, seen in Figure 4. Figure 4. A,C,E) Mouse studies depicting neuroprotective action of TFs, IGF/VEGF vs control. [Image adapted from Dodge et al., 2010] It is worth noting that combined delivery of both TFs showed no synergistic effect, probably due to their affecting the same pathway. Subsequently, in 2013, Krakora et al., modified human mesenchymal SCs to further investigate synergistic effect of combined GFs. A synergistic effect between GDNF + VEGF was seen due to their action on different signalling cascades. This shows promise for future studies into improved neuronal survival. SC conclusions Phase-1 clinical-trials have shown safety of SC injection into CNS with promising, if unreliable, patient outcomes. The mechanism of improvement still unidentified, but hints at inflammatory regulation in neural protection may open an interesting avenue. GF application shows further potential based on rodent/mice studies with a proven effect at slowing disease progression and neuronal loss. SCs make suitable GF vectors as can be made to express/over-express GFs. Combining GF models with SC vectors for targeted delivery requires further exploration. Future trials must consider frequency, dose and administration technique. Neuronal Excitotoxicity Mouse ALS models by Beers et al., (2011) and Liao et al., (2012) indicate microglia conversion from M2 (anti-inflammatory) to M1 (pro-inflammatory) state during disease. Believed to be due to glutamate toxicity, therapeutic work should focus on reducing excessive neuronal glutamate level, and reducing resultant pro-inflammatory response. In 2014, Mesci et al., studied the xC- system; a glial antiporter exchanging cysteine for glutamate release, causing increased neuronal glutamate. The study aimed to show blocking xC- would reduce excessive glutamate release and affect M1/M2 state, to reduce inflammation. xCT (transporter gene) -/- mouse microglial studies demonstrated a significant 70% reduction in glutamate release compared to XC- +/+. Furthermore, Figure 5 shows significantly increased pro-inflammatory factors in xC- +/+ mice microglia compared to -/-, hinting at a shift towards the M1 microglial phenotype via xC-. Figure 5. A-E) Levels of M1 pro-inflammatory factors in xCT -/- vs +/+ mouse microglia [Image from Mesci et al., 2014] Interestingly, Mesci et al., also noted a 10-fold increase in anti-inflammatory M2 marker levels at pre-symptomatic phase in -/- mice which drops off at disease onset, indicating M1/M2 shift upon disease onset. Encouragingly, -/- microglia showed significant increase in motoneurone survival in -/- vs +/+ microglia, at 45% and 35% survival, respectively. This is indicative of a less neurotoxic environment. Finally, xC- -/- SOD1 mutated mice showed an overall deceleration in disease progression, shown by increased survival rates following advanced disease stage (20% weight loss) in Figure 6. Figure 6. Survival in advanced ALS in xC- +/+ and -/- SOD1 mice Neurotoxicity conclusions These anti-excitotoxicity findings are consistent with the action of Riluzole. Future drugs may target xC- system, however current antagonists are poorly specific and available to brain. Identification of a more suitable antagonist would be a good priority before further clinical trials. Antisense Technologies Antisense oligonucleotides (ASOs) bind to specific mRNA sequences to cause mRNA degradation. In 2013, Leah et al., conducted studies in SOD1 rodents and human subjects with neurodegenerative diseases. SOD1-targeting ASOs were introduced to subjects to reduce SOD1 levels. They found both SOD1 mRNA and protein fell by 69Â ±4% and 48Â ±14%, respectively, in rodent cortices. Interestingly, this matched reduced protein levels by 42Â ±14% in rodent CSF, indicating CSF levels are a good measure of levels in brain. Unfortuntely, SOD1 cannot be a specific ALS marker due to its presence in other neurodegenerative diseases. However, its observed constant levels over time supports SOD1 as a good biomarker in indicating efficacy of antisense technologies and its effective targeting by ASOs may be useful in measuring brain SOD1 levels via CSF levels in future studies. A Phase 1 Clinical Trial by Miller et al., (2013) to determine safety of single-dose intrathecal injection of ASOs found no safety concerns. However, liver cancer and neuropathy was previously seen in cases of chronic low SOD1 levels (Elchuri et al., 2005), so long-term dosage effects must be carefully monitored. Conclusions This review was restricted to three main research areas, but areas such as susceptibility gene identification, oxidative stress and protein misfolding, are also being explored. Current research shows promise, especially in SOD1 rodent models and positive safety data from Phase 1 Trials. SCs continue to have vast potential, and when combined with GFs have shown encouraging effects on disease progression in rodent models. Reliability of these studies, however, must be improved in order to draw accurate conclusions and compare findings from related studies. Ideally, a ‘standard trial protocol’ should be implemented. Trials must also consider long-term effects of reduced SOD1 levels (in antisense techniques) and immunosuppressant use (with stem cells). Some issues may possibly be alleviated by recent development of new autologous SC models (Meyers et al., 2014). In short, current ALS treatments remain palliative care and Riluzole, but with new developments continuously emerging there is definitely an exciting research landscape ahead. In October 2014, ALSA requested Phase II Trial proposals to accelerate work in this area, meaning that the race is on to find suitable ALS treatment that may help patient prognosis in the future.

The Social Contract Tradition: Hobbes, Locke, Rousseau :: Philosophy Philosophical Papers

The Social Contract Tradition: Hobbes, Locke, Rousseau ABSTRACT: The classical contract tradition of Hobbes, Locke, and Rousseau have enjoyed such fame and acceptance as being basic to the development of liberal democratic theory and practice that it would be heretical for any scholar, especially one from the fringes, to critique. But the contract tradition poses challenges that must be given the flux in the contemporary socio-political universe that at once impels extreme nationalism and unavoidable globalism. This becomes all the more important not in order to dislodge the primacy of loyalty and reverence to this tradition but from another perspective which hopes to encourage that the anchorage of disclosure be implemented. The contract tradition makes pronouncements on what is natural and what is nonnatural. It offers what many have contended are rigorous arguments for these pronouncements that are "intuitive," "empirical," "logical," "psychological," "moral," "religio-metaphysical." What I offer in this essay is a challenge from the outside. I ask: 1) on what empirical data are the material presuppositions of contractarianism built? 2) what is the epistemological foundation of contractarianism? 3) is contractarianism not derivable from any other form of sociological presupposition except that of the state of nature? 4) does any human know a "state of nature"? 5) given the answers to the above questions, to what extent are the legal and moral foundations of contractarianism sacrosanct? I attempt to answer these questions in what can only be a sketch, but my answers suggest that it is very presumptuous of contractarianist to suppose that they have captured the only logically valid basis of democratic practice universally. Introduction The classical social contract tradition of Hobbes, Locke and Rousseau have, in spite of their variation in themes and emphases, enjoyed such fame and acceptance as being basic to the development of liberal democratic theory and practice that it would be almost heresy for any scholar, especially one from the fringes or margins of mainstream (socio-political) philosophical academia, to post frontal, side, arial, rear or sub-surface attack and critique. But the social contract tradition poses challenges that must be accepted on various counts, with new insights and interpretations, given the fluxed reality in contemporary socio-political universe that at once impels extreme nationalism and unavoidable globalism. This becomes all the more important, not simply in order to dislodge the primacy of the loyalty and the reverence of devotion from the followers of this tradition

My Life with Thoreau Essay example -- How Education Has Changed My Life

It was my high school teacher, Anna Shaughnessy, who introduced me to Henry David Thoreau. His Walden was not part of the course of study. She asked whether I knew of this Massachusetts writer. I didn't. Without scaring me off by proclaiming how great he was, she said he had lived and died in obscurity. But not like some romantic poet in a dusty garret. He had done all kinds of work for a living-been a schoolteacher, surveyor, pencil-maker, gardener, carpenter, mason, lecturer, naturalist, as well as keeper of a personal journal into which he wrote two million words. "Thoreau was born in 1817, about a hundred years before you," Miss Shaughnessey said. "But I think, when you read him, you'll find his ideas, his way of looking at life, will mean as much to you as if he were born yeste...

Productive Opportunity Essay

Productive opportunities depends on multiple things, the advancement of technology, the availability and access to resources, and also what producers and entrepreneurs can think of at the given time. Choosing a combination of productive and financial opportunities help maximize wealth. They key in finding a productive opportunity is a high degree of awareness of the factors that distort judgment A perfect capital market is when buying and selling do not affect prices. â€Å"In a perfect capital market the corporation is regarded only as a means of generating wealth, because the present value of the dollar returns it generates is the only feature relevant to its owners.† Understanding your resource, resources is a source or supply from which an organization gains profit. Typically resources are materials or other assets that are transformed to produce benefit and in the process may be consumed or made unavailable. From a human perspective a natural resource is anything obtained from the environment to satisfy human needs and wants. Organizations operate by people making decisions. A manager plans and organizes a team by executing decisions. The effectiveness and quality of those decisions determines how successful a manager is. With this being said â€Å"the goal of the manager and owner remain the same as long as market value is maximized.† Opportunity is all around us but yet at the same time sometimes we never see it. In business we look for new ways to market our business, reach our target market, build on online community and through this all we overlook the opportunity that is all around us. We are learning to create opportunity my maximizing our market value. In conclusion, â€Å"in a perfect capital market, the market value of the ï ¬ rm is determined only by the cash ï ¬â€šows it can generate and not by the source of funds used to ï ¬ nance those operations. The task of management is to create wealth by ï ¬ nding productive opportunities with average rates of return exceeding the market rate of interest.† Fabozzi, Frank J. (2011-12-01).

Lyle Alzado View of Steroid Use

Also I was undersized compared to the other players. After graduation no colleges gave me scholarships for playing football. Being undersized and playing averagely I wasn't the best athlete. I tried out for the Kilgore Junior College's football team in nineteen sixty four, but they told me that I wasn't good enough to play for them. I was finally accepted to Yankton College in South Dakota; I started taking steroids to play football better after being accepted, in order to play better and to insure my place on their football team.In nineteen seventy one I was the Denver Broncos fourth draft pick. I was a defensive lineman the same as in high school. I became a formidable player by the end of my rookie year. I outran, outwit, authenticated everybody. All along I was taking steroids and I saw that they made me play better and better. In nineteen seventy seven, I was named the Oaf's defensive player of the year and the defensive lineman of the year. I went from being and average player in high school, to being a feared professional football player in Just a few years.I was so wild about winning, it's all I cared about, I never talked about anything else, and steroids helped me keep on winning. In nineteen eighty four, I retired from football due to an injury to my Achilles tendon, which I believe was cause by my steroid use. I tried to make a comeback in nineteen ninety with the Raiders but I immediately had a knee injury that prevented me from playing. By the end of my football career I was name all-pro twice and had a total of ninety seven sacks In one hundred ninety six games. I had done well for someone who had no hope In high school of playing professional oddball.All during my college and professional football career I was taking steroids. I spent around thirty thousand dollars a year on steroids. All the time on the field I was fierce, mean, and determined to win, but off the field I had a hard time turning these emotions off. One of my teammates described me as have a split personality, â€Å"on the field he projected a tough image,† He said. But off the field I was like a gentle giant. When the game was over, I would be plagued with mood swings from the steroids; I could keep a good relationship with people.I was married four times over the course of my football career. Once a man sideswiped my car in Denver and I followed him home and beat him up In his front yard. I couldn't control my anger. I abused my second wife so much that she called the police five times on me during the course of our marriage. In March of nineteen ninety one, during my wedding to my fourth wife Kathy, I had a hard time keeping my balance while walking. A month later I was diagnosed with a chemotherapy treatment, in an attempt to cure the brain tumor.I died over a year after being diagnosed in my home in Portland, Oregon. I told Sports Illustrated before my death that I had started taking steroids in nineteen sixty nine and never stooped. I wanted to tell others to stop taking steroids. It wasn't worth it to me, steroids caused me to become detached from my friends and family, I couldn't keep a good relationship due to the mood swings caused by my steroid use. Ultimately my death was caused by steroids, they had made my appear strong on the outside while they wrecked my mind and body.
