Strategic Human Resource Development - Essay Example However, there are areas of significant importance - like training - that have been excluded from the control of Personnel Department and are organized into separate units within the organization. Due to the above phenomenon as well as to the delays in the firm's development - which have been caused by the dysfunction of the Personnel Department - the examination and the evaluation of the role of the latter has been considered as necessary especially given the extremely competitive conditions that characterize the UK market. Current Personnel Function of Highway Stores Ltd is based in the firm's head office in Midlands. Furthermore, the specific department comprises a Personnel Manager, a Personnel Officer and 3 Personnel Administrators. The main duties of the staff include the control of all issues related with the firm's human resource management except the payroll sector which has been incorporated in the Finance Department. The Personnel Function reports directly to the Legal Director. Another significant problem is created by the fact that there is not a specific provision for the training of the head offices' personnel (training programs as designed and developed by the Training function involves only the employees of the store network). On the other han On the other hand, the Personnel function has not proceeded to the design and implementation of a specific problem-solving procedure but there is a standard internal policy that whenever a problem arises, a guidance is issued. The absence of control over the training procedure as well as the failure of designing and applying an effective personnel policy can be considered as major problems for the Personnel function. Moreover, the lack of appropriate qualifications of the Personnel staff can be viewed as a severe disadvantage of the specific department while due to this fact; most of the problems arising in the human resources field have to be faced by the only qualified person of the department, its Manager. It's for this reason that Personnel Manager is not available for his managers whenever his intervention is requested by the Personnel staff. At a next level, a major weakness of the Personnel function is the procedure related with the sickness of employees. The Personnel function keeps records on employees including health certificates as well as notices on the employees' long term absence of work (six weeks or more) due to sickness. In this way, the department is not informed for the employees' short or long term absence of the work (except the above mentioned case) with all the consequences that this fact can have for the effectiveness of the firm's human resource management. Another problem involves the extension of the role of the Personnel function is the recruitment process. The specific process is designed and implemented by the Managing Director, while the responsibility for the recruitment of new staff belongs to Area managers. It should also be noticed here that

Waiting for the Barbarians by J. M. Coetzee Essay Example for Free
Waiting for the Barbarians by J. M. Coetzee Essay All this erotic behavior of mine is indirect: I prowl about her, touching her face, caressing her body, without entering her or finding the urge to do so. But with this woman it is as if there is no interior, only a surface across which I hunt back and forth seeking entry. Is this how her torturers felt hunting their secret, whatever they thought it was? pg.43. One of the central figures in J. M. Coetzees Waiting for the Barbarians is the barbarian girl. The Magistrate finds the girl maimed and nearly blind after being interrogated and tortured by the ruthless Colonel Joll, and takes her in. The Magistrates relationship with the girl revolves around his search for the girls significance; he questions her about her torture, he attempts to understand her through her physical surface, and tries to use her as the key to unlocking his own meaning. Ultimately, the Magistrates treatment of the barbarian girl mirrors her treatment by Colonel Joll; they both use her as a tool in their respective searches for knowledge. The parallels between Joll and the Magistrates behavior towards the barbarian girl can be seen in the selected passage. The Magistrate is going over his conduct towards the girl in his head, and expressing some puzzlement as to the motivation behind his actions as well as over their lack of fruition. He puts effort into making romantic gestures towards her, but does not sleep with her, nor does he really want to. He seems to want something from her, but is unsure about what that is or how to go about getting it. This makes the woman seem mysteriously full of meaning and yet impenetrable to him, in more ways than one. His last thought is to compare his search for meaning in his relationship with the girl to her torturers search for an elusive secret from her. By describing his own behavior as indirect, we get a sense of the Magistrates own lack of clarity towards the subject. He makes erotic overtures towards the girl, but he makes them indirect[ly], implying that his goal is not to seduce the girl but what his true intentions are remain unclear, even to him. The Magistrate does not understand his fascination with the barbarian girl. This can be illustrated on pg. 40 whereà he asks her not only why she is with him, but also, why do I want you here? He tries to analyze his relationship to the girl and use it to somehow get a better understanding of who he is. However, his philosophical questions get few answers from her, and none that satisfy him. He focuses his interest on her scars and what transpired during her torture sessions, questioning her incessantly. He bathes her and massages her with almond oil, paying special attention to her injuries. Using his hands to feel all over her body, repeatedly he tries to recreate in his mind the whole of what she was like before the torture, the whole of the person she is and was. Yet it seems to him as if she has no interior, only a surface across which I hunt back and forth seeking entry. Because he cannot find her interior, or the meaning that she holds for him, he blindly searches the physical surface for meaning. The Magistrate tries to interpret his own meaning through the girls body. Like the wooden slips covered in barbarian characters that the Magistrate polished and pored over for so many hours, her oiled body becomes a text to decipher his own meaning. When she grudgingly reveals some of the torture methods used on her, it does not bring her and the Magistrate any closer together, neither does it bring the Magistrate any closer to understanding her; interestingly enough, it functions to give the Magistrate more insight into Jolls character and his relationship to him. Her scars are like the ugly truth of the Magistrates quiet complicity in the atrocities committed in the name of Empire that he must bring himself to reconcile with, by looking at them and feeling them over and over again. Once the Magistrate begins to realize the role he had in facilitating the acts of torture, and how horrendous they truly were, he also begins to see the similarities between Joll and himself. The verbs the Magistrate uses to describe his own actions towards the girl in the selected passage, such as prowl, hunt, and even seeking create an image of a furtive predator rather than a lover. This is a manifestation of the guilt he feels for his part in her injuries. But we do not get a real sense of threat or danger from the Magistrate because he states that this hunter is non-invasive: he does not enter her and has no urge to do so. Even the phrases touchingà her face, and caressing her body, which normally would invoke intimacy, when put in the context of prowling give the impression of a hunter thoroughly examining the pelt of its prey. It is easy to make the connection between this image and the image of the Magistrate examining the barbarian girls broken ankles and scars. Joll and the accomplice torturers are also referred to as hunting the girl; while Joll was aggressively searching for a secret he never found, the Magistrate hunts for how to figure her out and enter her surface, which he also fails to find. However, they both hunt for some sort of meaning from this girl, suggesting Jolls use of her is similar to the Magistrates use for her. Joll tortures her to try to get secret information about an impending barbarian offensive attack (which turns out to be nonexistent information in the first place). However, he still hunts the truth from her until she is left blinded and crippled. The Magistrate presses for details of her torture, harasses her with philosophical questions, and engages in his cryptic washing and oiling rituals while searching for meaning through her body. In his various ways he also tries to hunt out meanings from the girl, and he comes to realize his relationship to the girl thus mirrors that of Jolls. They both use the girl as a means to some desired end of knowledge, whether it be a secret of war or a secret of why. Furthermore, the Magistrate comes to see his mirroring of Joll might not just end with the barbarian girl. The girl ultimately serves as the interface for the Magistrate to see the parallels between himself and Joll. It is significant that the Magistrate takes up with the girl only after Joll has discarded her- the fact that the Magistrate must have overseen her arrival with the soldiers was a recurring thought of his. However, he had no interest in her until after Joll had left her permanently handicapped. The Magistrate eventually comes to see that his attempt to connect with the woman was an attempt to retrace Jolls footsteps; to understand the manà and his actions by putting himself into an intimate relationship with the barbarian girl. But he also does this to distinguish himself as different from Joll; he regretted he could not engrave [himself] as deeply (p.135) on her as Joll had, but he wished to leave the mark of his pseudo-loving on her rather than the marks of pain and torture she had from Joll. The relationships the barbarian girl has with Colonel Joll and the Magistrate are similar in that both use her as a tool in their respective quests for knowledge. Joll tries to coerce her into saying something to justify an attack on the barbarians, while the Magistrate tries to use her to interpret himself and his role in the Empire, but they both believe that she is the key to unlocking some truth they seek. They both use the girl for their own purposes, without any regard for her as a person, and Joll treats her very cruelly. The Magistrate cares for her physical well-being, but he does not truly attempt to get to know beyond her surface, and only attempts to understand her through what function she serves in his life. Eventually he realizes through his relationship with her how many parallels exist between him and Joll. The girl stands between the two men as a one-way mirror that they both use, but gradually becomes two-way for the Magistrate, allowing him to see the Joll alter ego mingling with his own reflection. Coming to accept this also means collapsing some of the distance that he had mentally established between himself and Joll, and likewise accepting a certain share in the responsibility for all the atrocities committed by Joll in the name of the Empire.

Prediction Of Cutting Forces In Broaching Operation Commerce Essay
Prediction Of Cutting Forces In Broaching Operation Commerce Essay According to variety of workpiece profiles in broaching, the geometry of cutting edge varies from simple line to very complicated curves. Wide range of cutting edge geometry in broaching imposes complexity to the distribution of the chip load along the cutting edge. Hence, prediction of cutting forces in broaching is not as simple as other machining processes. Due to this complexity, introducing an applicable force model for all of the orthogonal and oblique broaching cutters can be problematic. In this paper, an attempt is made to present a new force model for broaching. The newly proposed force model expresses the cutting edge as a B-spline parametric curve and uses their flexibility to calculate the chip load as well as cutting forces for orthogonal and oblique broaching. Verified by experimental results, the presented model has a great capability to simulate broaching cutter geometry along with cutting forces and it can be applied for the entire broaching cutters. 1. Introduction Broaching is a powerful process for the production of complex internal and external profiles. As a machining process, it is commonly used for the machining of a broad range of profiles such as keyways, guide ways, holes and fir-tree slots on turbine discs. Broaching has considerable advantages in comparison to other machining processes. Roughing, semi finishing and finishing of a complex profiles can be done in one stroke of the machine which would require many passes in other conventional processes such as turning, milling, slot milling, etc. It can also produce parts with high surface quality and high geometrical and dimensional tolerances in one stroke. Since the number of simultaneously engaged cutting edges with the workpiece is higher than the other cutting tools, the chip load on each of them will be smaller and tool life is distinctively longer in comparison to other machining processes such as milling and turning [1]. It can be also mentioned that broaching machines are not as complicated as CNC milling or CNC turning machines and thus considered as a simple operation that requires not a highly skilled operator. In other commonly used machining processes such as milling and turning, final geometry of workpiece is generated by combination of tool and workpiece motion and there is no similarity between final geometry of workpiece and cutting tool geometry. In broaching, the geometry of machined part is derived directly by the inversion of broaching cutter geometry. Therefore unlike other machining processes, broaching cutters have a wide range of geometries as well as parts. Consequently, chip load has a complicated non-uniform 2D or 3D geometry depending on the profile complexity of workpiece. A unique feature of broaching operation is that it is not possible to change any of the cutting parameters during process but the cutting speed. That is because all other cutting parameters such as feed, depth of cut and width of cut are built in features of broac hing tool geometry which makes the tool design the most important aspect of broaching. Although broaching is well defined in industry, just a limited number of researches have reported work in the open literatures. In 1960 Monday [2] presents the most comprehensive source on broaching. A detailed description of broaching technology can be found in his book. Kokmeyer [3] edited collection of works on broaching representing the usefulness of the process. Gilormini et al. [4] analyzed the cutting forces on a single broaching and compared them to the forces in slotting and tapping process. Terry et al. [1] presented a system for optimal design of broaching tools. They presented the factors that affect productivity in broaching and explained the design constraints, their importance and how they are selected. Finite element was used to predict the tooth deflection and experimental data in order to create the general rules for designing. Sutherland et al. [5] presented a force model for broaching based on the oblique analysis to determine the forces in the gear broaching proc ess. Their model showed the relationship between contact area, chip load and cutting force. Sajeev et al. [6, 7] investigated the effects of broaching parameters on the tool and workpiece deflections and the final shape of the broached geometry. Budak [8] examined the performance of broaching tools used for broaching of waspaloy turbine discs with fir-tree profile based on the monitoring of force and power. It has been demonstrated that for most of the investigated tools, the load distribution among the broaching sections were non-uniform resulting in uneven wear. Recently Ozturk and Budak [9, 10] performed Finite Element Analysis to calculate the stresses in the broaching tool during the cutting process. The developed model is used to simulate the broaching process and predict the generated stresses in the tool to improve the tool design. He studied fir-tree profiles, simulated the broaching process forces and the tool stresses to improve the tool design. Later Kokturk and Budak [1 1, 12] performed an optimization on the geometry of the broaching tool cutting edges. In their study the cutting conditions are changed until they can satisfy the preset constraint. They also used the optimized conditions to improve the broaching process. Yussefian et al. [13] applied B-Spline parametric curves in modeling of boring process. Recently Hosseini and Kishawy [14] presented a general force model for orthogonal broaching using B-spline interpolation of cutting edge. By taking geometric flexibility of B-spline curves, their model was capable of modeling any arbitrary orthogonal broaching cutting edge geometry as well as computing the chip load for various cutting conditions. This paper proposes a 3D general force model for the broaching process. The proposed force model is capable of modelling of three force components using B-Spline interpolation of the cutting edge. Each cutting edge is first modeled by B-Spline parametric curves then the chip load is calculated by integ ration of area between two successive edges. The proposed force model for orthogonal and oblique broaching can calculate the chip load for any arbitrary geometry of cutting edge from the simplest to the most complicated. The proposed method is used to calculate the generated forces and the results are compared to the measured data. 2. Broaching tool geometry Broaching tool is a straight multi tooth cutter in which several cutting edges engage with the workpiece simultaneously and each tooth removes a portion of material from workpiece surface. Broaching cutter has a tapered flat or round profile with a series of teeth on its surface [4]. Each successive tooth in a broaching tool is higher than the preceding one to perform the cutting action and remove material from workpiece surface. Broaching cutters in their general form can be geometrically divided into three categories of teeth, namely, roughing, semi-finishing and finishing teeth. Roughing teeth remove the bulk of material from workpiece, semi finishing teeth produce the basic surface finish (surface quality), and finishing teeth provide the final surface finish and set geometrical and dimensional tolerances [4]. Figure (1) shows a typical broaching cutting tool. Figure 1: Schematic view of broaching tool Normally the maximum rise per tooth in broaching tool belongs to the roughing teeth which perform the major part of metal removal. The rate of rising per tooth slightly decreases in semi finishing teeth as they only remove a small portion of material from workpiece surface to improve the dimensional accuracy and surface quality. In the finishing part, all of the teeth have the same height. These teeth are not cutting teeth and they provide the desired surface quality and adjust the geometrical and dimensional tolerances in the predefined range. Figure (2) illustrates the general mechanism of cutting in broaching. Figure 2: Mechanism of cutting in broaching When broaching cutter is accurately designed, broaching process can be faster and more accurate than many other machining processes. Although the initial cost of establishing for a broaching process is comparatively higher than that of other cutting processes, the production cost is commonly low because of the high production rates and the long tool life. Figure (3) presents some of the important geometrical parameters of broaching cutting tool. Figure 3: Broaching tool geometry In figure (3), and are rake angle, clearance (relief) angle, tooth height and land length respectively. The rake angle and clearance angle can be selected based on workpiece material. The rake angle is usually selected between to and clearance angle is usually selected between to [12]. The total length of the tool and number of simultaneously engaged cutting edges can be determined by the pitch length which is a linear distance between two successive cutting edges. Based on some previously conducted research [10, 12, 15], it is concluded that it is preferable to have at least two cutting edges in cut to have a dynamically stable cutting. Another geometric feature of broaching tool is gullet space which is the empty space between two following teeth. The main advantage of gullet space is to retain the chip during cutting until the tooth leaves the workpiece. Once the broaching tool engages with the workpiece, chip is captured between tool and workpiece and it is maintained there until each tooth finishes the cut and leaves the workpiece. Small gullet space may cause tool breakage because of no space to keep the removed chip. It can also lead to poor surface finish due to rubbing of removed chip to the machined surface. If the gullet space is chosen too large it makes the tool very slender and decreases the tool strength and stability. According to the above mentioned reasons, it is very important to design the gullet space accurately to achieve acceptable space and dynamic stability simultaneously. In order to perform a reasonable design it is necessary to have a good understanding of cutting forces during machining p rocess. If the force model can predict the cutting force truthfully the result of force simulation can be used as an input for design and optimization process. 3. Mechanics of metal cutting in broaching Similar to almost all of the cutting processes, the cutting force in broaching can be expressed generally by three differential components which are directly related to chip load area and the contact length between cutting edge and workpiece such that [16]: (1) Figure (4) depicts the main features of oblique broaching and shows the force components generated during the chip removal process. Figure 4: Mechanics of oblique broaching In equations (1), is the differential component of tangential force, is the differential component of feed force and is the differential component of radial force. and are chip thickness and length of the cut for infinitesimal element along the cutting edge respectively. and are cutting and edge constants while the subscript refer to the tangential, feed and radial directions. Similar to the other cutting mechanics, the radial component of force appears only during oblique broaching when cutting edge has an inclination angle with the cutting direction. The total tangential, feed and radial component of cutting force for each edge can be calculated by integrating of those components along the cutting edge. Equation (2) shows the force integration along the cutting edge from the start to the end of engagement. (2) In equation (2), represents a differential element of chip area which is removed by the cutting edge. Equation (2) can be written in this format: (3) In the above equation, is chip load along the cutting edge and is length of engagement between cutting edge and workpiece. Figure (5) demonstrates the infinitesimal element of cutting edge, chip load and contact length for an arbitrary fir tree broaching tool. Figure 5: Infinitesimal element of cutting edge Since the chip load may vary along the broaching edge, it must be segmented into elements for which local thickness can be assumed constant. The geometry of chip along the broaching cutting edge is complicated however, since there is no relative motion between successive edges the chip load remains constant. The common approach for simulation of cutting forces is dividing the cutting edge to infinitesimal elements and calculating the area for each element separately. If total chip area can be calculated, cutting forces are obtained without the need for dividing the edge to elements. However, due to the variety and the complexity of cutting edge profiles in broaching, it is difficult to express the edge by an explicit function. Hence, calculation of the above integration in equation (3) is not a straight forward procedure. Representing the broaching cutting edge by B-Spline curves is a powerful way to express the geometry with parametric relations which makes integration and derivatio n along the edge much easier process. 4. Cutting edge interpolation by B-spline parametric curves A series of data point can be obtained by collecting the coordinates for each point along the cutting edge using inspection method such as CMM, digitizing or laser scanning. The desired B-Spline of degree p defined by control points passes through all those data points and expresses the cutting edge by a parametric curve. This parametric representation of the cutting edge can be easily appllied to perform derivation and integration along the edge to find the chip load area and the total engagement length. The interpolated B-spline cutting edge of degree p can be expressed as below [17-19]: (4) Where is interpolating B-Spline curve of degree p, is control points which control the geometry of curve and is B-spline Basis functions which can be computed by: (5) In equation (5), is a B-spline knot which belongs to the knot vector of . The equation (4) has unknown control points. For this reason, it is necessary to have a parameter like to relate the control points to the data points. Since parameter corresponds to data point , plugging into the above equation yields the following [19]: (6) There are n+1 B-spline basis functions and parameters in equation (6). Substituting t in to , these values can be organized in a matrix N as shown as below: (7) Data points and control points can be expressed in similar way: (8) And (9) In equation (9) matrix D is input data points which are represents the points along the cutting edge and matrix N can be obtained by evaluating B-spline basis functions at the given parameters [19]. D and N both are known and the only unknown parameter is matrix P. Equation (9) is a system of linear equations with unknown P, solving for P yields the control points and the desired B-spline interpolation curve becomes available. Figure (6) shows control points and desired interpolated broaching cutting edge using B-spline curves. Figure 6: B-spline interpolation of cutting edge 5. Calculation of chip load and contact length In orthogonal broaching, all of the cutting edges are parallel together and perpendicular to the cutter axis therefore the third column of matrixes and in equation (8) are zero and only two parameters of and in equation (4) is needed to represent the cutting edge. Figures (7a) and (7b) depicts a typical Cartesian coordinates in orthogonal and oblique broaching. (a) Orthogonal broaching (b) Oblique broaching Figure 7: Cartesian coordinates In contrast with orthogonal broaching in which all teeth are perpendicular to the cutter axis, in oblique broaching cutting edges have an oblique angle with cutter axis but they are still parallel to each other. In this case , , and all of the coordinates in the third column of matrixes and are non zero. B-spline interpolation of 3D curves is possible but little bit time consuming so it is preferable to transform the 3D to 2D and use the same method for 3D after transformation. Coordinates of point in Cartesian coordinates can be expressed by in plane as follows: (10) The above transformation can be done for all of cutting edge data points and in the new coordinate system matrixes is as follows: (11) Once matrix presented in new coordinate system the interpolation process can be done the same as previous method for 2D curves. As soon as the cutting edge is presented by B-Spline curves, chip area and cutting length for each cutting edge can be calculated directly from B-Spline equations as follows [13]: (12) Where indicate start of the cut, end of the cut, current cutting edge and previous cutting edge respectively. Equation (12) has two coordinate parameters and it is applicable for calculation of chip load and contact length for orthogonal and oblique broaching. 6. Cutting forces simulation In order to compare the presented geometric model with a real case, a broach cutter was selected and its cutting edges were modeled using B-Spline curves. The geometry of cutter was chosen based on previously presented research by Kokturk [12] to validate the newly proposed model capability. Figure (8) demonstrates the cutter geometry. Figure 8: Cutter geometry The geometrical features of cutting edge can be found in table (1) [12]. Table 1: Geometry of broaching cutter [12] In the next step, selected cutting edges were interpolated using proposed approach. Similar to other interpolation methods, B-Spline interpolation is sensitive to the number of data points. Increasing the number of data points yields a better accuracy but it makes the running time of the algorithm longer. Decreasing the number of data points, accelerate the algorithm but it has a negative effect on the accuracy. It has been shown that smooth parts of the curve are not very sensitive to the number of data points because inaccuracy occurs in the sharp corners where the curve direction changes suddenly. As a result, it would be better to use more data points at the sharp corners and less data point at the other parts to increase the accuracy and time efficiency of the algorithm simultaneously. Figures (9a) and (9b) show the B-Spline presentation of two successive cutting edges. (a) B-spline representation of the first cutting edge (b) B-spline representation of the second cutting edge Figure 9: B-spline representation of two successive cutting edges It can be seen from the above figures that B-Spline curve follows the data point at the sharp corner with high accuracy. 7. Results and discussion Figure (10) shows the final geometry of workpiece. Cutting conditions and force coefficients which are used in simulation can be found in table (2). Figure 10: Final workpiece geometry Table 2: Cutting conditions [12] 5 Since the cutting edge without oblique angle doesnà ¢Ã¢â ¬Ã¢â ¢t have radial component of cutting force it was assumed that for this special case. The edge coefficients of cutting force are always very small in comparison to cutting coefficients so it has been assumed that , and are negligible. Figure 11: Simulated and experimental cutting forces for orthogonal broaching Figure 12: Simulated and experimental resultant force for orthogonal broaching Figure 13: Simulated and experimental cutting forces for oblique broaching Figure 14: Simulated and experimental resultant force for oblique broaching It can be seen from figures (11) to (14) that the results of newly proposed model are in good agreement with the previously published results [12]. Since there is no oblique angle in orthogonal broaching the cutting edge engaged with workpiece suddenly with full length so there is a jump in force diagram when each tooth engaged with workpiece. Due to presence of oblique angle in oblique broaching the tooth engaged with workpiece smoothly so the cutting forces rise gradually from zero to its final value. Also, in oblique broaching, fluctuation of cutting forces in the steady state part of the cutting is less than orthogonal one because when one of the teeth leaving the workpiece another one engages smoothly but the average force is higher because of longer contact length. 8. Conclusion In this paper, a force model is developed to simulate the cutting forces in orthogonal and oblique broaching using B-spline representation of the cutting edge. The new model can interpolate broaching tool cutting edge without any limitations which offer the simulation of cutting forces for any desired input geometry. In order to validate the new force model, the predicted cutting forces are compared to previously measured data [12]. The comparison showed a good agreement in both measured and predicted data for orthogonal and oblique broaching. The simulated cutting forces can be used to have a better understanding of process and optimize the geometric features of broaching cutter to achieve more efficient cutting which is under investigation of authors.

The Best Ethical Practices And Values Of Greenpeace Politics Essay
The Best Ethical Practices And Values Of Greenpeace Politics Essay Greenpeace is a renowned Non-Governmental Organisation founded by Dorothy Stowe, Irving Stowe, Dorothy Metcalfe, Jim Bohlen, and Bob Hunter; to fight for the environmental degradation, since 1971. According to Greenpeace Annual Report 2001, Greenpeace is an independent campaigning organisation that uses non-aggression and mediagenic confrontation to expose global environmental issues, and to force solutions which are significant to a greener and peaceful future (Greenpeace, 2001). The organisation is currently campaigning for the safeguard of the oceans and forests by switching fossil fuels to renewable energies, abolishing the use of toxic chemicals, opposing the use of genetically-engineered organisms, and to discontinue nuclear armament as to make an end of radioactive contamination. Ethical perplexing situations faced by Greenpeace Ethical dilemma is a state of involving difficult of choices between conventions (Fisher Lovell, 2003). As we know, ethical dilemma is stressing on the action of preserving a debate problem and to maintain ethical manners rather than looking for an excuse to end the debate. In recent year, Greenpeace is distressing by the ecological issues as stated below:- Genetic-Engineering In this 21st century, human population is increasing exceedingly and climate changes have causing the food production to be threatened. This issue has create a dilemma on the population at large, and because of this issue, scientist has come out with a solution of Genetic-Engineering (GE) which is creating plants, animals and microorganisms by modifying their genomes (Greenpeace, 2010). Besides that, Genetic-Engineering has create a negative impact on agronomic activities; for example, engineered plants found defenceless towards pests and diseases, and creating genetic contamination spreading uncontrollably through interbreeding with other natural organisms. And because of this case, Greenpeace has taking initiative to prevent the contamination of genetic-engineered genomes to the society at large. Climate Changes The climate changes is the major threat for global environmental, and based on the report it claimed that the continuing of use of fossil fuels which triggering the climate rapidly change (Greenpeace, 2002). The climate change has impacts on the agronomic production and creating natural disasters such as erosion, flooding due to the rise of sea level and has risk the population at large and triggering the extinction of the wildlife. Besides that forest devastation also the reason climate change occurred. Greenpeace claimed that one fifth of the global greenhouse gas release due to industrial logging (Greenpeace, 2010). Nuclear Activities Since the bombing of Nagasaki and Hiroshima in Japan, nuclear activities have growing rapidly even the end of cold war, and besides that, the level of nuclear stockpiled still remain relatively high. In the report of world nuclear stockpile by Ploughshares Fund (2010) mentioned that there are total of 22,500 nuclear stockpiles in worldwide and over 8,190 warheads still operational (Ploughshares Fund, 2010), and this issue has concern Greenpeace since 1976; to fight for the safety of the people and the environment as to prevent catastrophes of nuclear explosion, warfare, and waste disposal issues. Based on Patrick Moore statement said that nuclear power plants are the next nuclear weapon which is the most hazardous devices has ever made (Moore, 1976). Based on the statement, we knew that Greenpeace never tolerate the uses of nuclear power plant which can convert to nuclear weapon which will harm the people and environment. Industrial Fisheries In recent year, the fishing industries have growths rapidly, and almost more than 70% of the world fisheries are abused by human (Greenpeace, 2010). This is because overfishing has become so common in today world besides that this issue has cause a great change in marine ecosystems which might cause extinction of the oceanic creatures in nearer future, In addition to this besides overfishing, by-catching has also creating a severed environmental impacts towards the marine ecologies because all of the by-catch creatures are threw away into the ocean after netted by the fishermen. The approach used to overcome the ethical issues The Greenpeace ozone campaign [mid-1980s-1992] The ozone campaign is to safeguard the ozone layer from being depleted. The depletion of the ozone layer is causing global warming due to the thinning of the ozone layer. The approach used by Greenpeace is public outreach where the organisation informing the public pertaining about the urgency of ozone layer depletion, and to catalyse public concern and demand for appropriate action from governments and corporations (Mate, 2001). Moreover, the materials that used for informing the public are publication of information video, publication of reports, brochures and leaflets, and public protests based on John Mate; to persuade the world about the danger of ozone depletion and to discourage the public to use substance which might hurt the ozone. Besides that, Greenpeace also involve in the commercial market, to initiate the public to switch to hydrocarbon refrigerator in 1992 from CFC refrigerator. Based on the case study, Greenpeace is using Kantian ethics. Kantian Ethics is stressing on the characteristic of dignity and moral equality of persons provided a principled rationale for resisting the more concerning features of consequentialism (Tiffany, 2006). The ethical values used by Greenpeace has shown the public that human error has cause the ozone to be depleted, and it is very essential that we (public) should change as to prevent further deterioration of the ozone layer. The benefit of Kantian ethics has a powerful and clear outline which well fit to everyones. Besides that, Kantian theory has played a good role in Greenpeace code of ethics where most of the Greenpeace employees followed. In addition, Immanuel Kant concludes that nothing can possibly be conceived in the world, or even out of it, which can be called good, without qualification, except a good will (Immanuel, 2008). Apple Inc. and Greenpeace [2008] Based on Patrick Schultz and Duane Helleloid (2010) statement said that Greenpeace challenged Apple due to their poor score on reducing the use of toxic chemicals such as Polyvinyl Chloride (PVC) and Brominated Flame Retardants which is hazardous towards consumers. However, Apple declines to address the criticism by the Greenpeace activist about their products, recycling and the use of hazardous chemicals. And because of that, Greenpeace launched GREEN MY APPLE a campaign against Apple as to raise awareness of Apple environmental inadequacies in the society. This campaign is to initiate Apple to improve their company policies towards the environmental impact. (Schultz Helleloid, 2010) Based on the action Greenpeace has taken, it has shown that the theory of utilitarianism is being used. Utilitarianism is the moral course of action in which promoted the great happiness of the greatest number of people as to make the world a better place (Rawls Sen, 2009). The action has taken by Greenpeace is try to show Apple that what they are doing is not right because the substance uses by them are hazardous to consumers. Moreover, this case is quite similar to ozone depletion case where however the differences is Kantian rules is absolutism where the public must exercise or face the consequences of depletion but in utilitarianism is a choice of change or face consequences; e.g. if Apple stop using hazardous chemical on their product, they can protect the environmental impact as well as the health of their consumers; if they failed to practice their consequences is the public and the environment might face severe risk that is the purpose of Greenpeace try to convince Apple wha t they are doing is not right. In addition, David Crocker concludes that Humans are not only experiencers or preference satisfiers; they are also judges, evaluators, and doers (Crocker, 1997), and the reason Greenpeace became the ears and voice for the welfare of the public and environment. Greenpeace condemning against Papua New Guinea (PNG) development PNG main sources of income are based on forestry due to their land is unfitted for farming except for tree crops such as cocoa, coffee, palm oil, etc. However, according to Tim Curtin (2006), he mentioned that Greenpeace condemning PNG tree logging is based on unusual norms. Moreover, the condemning of Greenpeace is based on the information provided by Forest Trends which considered secondary sources of information based on the author the term illegal logging is a term can cover a broad range non-forestry legal issues such as work permits, expatriate staffs, training, health and safety, which has nothing to do with forestry issues in PNG (Curtin, 2006). Base on this case, Greenpeace has make an unethical condemnation against PNG in which against their main core values of seeking solution, promote open, informed debate about societys environmental choices (Greenpeace, 2010). Besides that, they are did not exercise their campaign strategies and policies values to take great care to reflect their fundamental respect for democratic principles and to seek solutions that will promote global social equity (Greenpeace, 2010). In PNG case, Greenpeace ignored the promotion of global social equity and did not observe the condition in PNG besides taking second hand information to support their criticism. Besides that, there is no ethics of care in this context; according to Helena Stensà ¶ta (2010), she said look into the context of the ethical dilemma in order to resolve it, and it regards moral development as advances in our understandings of responsibilities and relationships (Stensà ¶ta, 2010). Based on her explanation, Greenpeace should put themselves in PNG shoes; to understand their condition rather than jump into conclusion without knowing what actually happen there, and besides that, Greenpeace should not relied on the information obtained from Forest Trends since Greenpeace did not have sufficient information pertaining PNG logging issues as stated by Curtin. In addition, the answer of ethical dilemmas must always be dedicated on preserving the relationships between people (Aerostudents, 2010), and not pinpointing others. Greenpeace succeeded in obstructing Greenlands opportunities to secure their economic foundation for its peoples life condition and he regards Greenpeace action as being a very grave and illegal attack on Greenlands constitutional rights, and it is highly disturbing that Greenpeace in its chase on media attention with all measures breaks the safety regulations put in place to protect people and the environment by Greenlander Prime Minister (Pearse, 2010).Greenpeace against Greenlandic economic development Greenlanders are critically dependent on fisheries, shrimps and metals exports, and cultivating forage crops, garden and greenhouse vegetables as well as domesticating sheep, reindeers and fishes for local uses (CIA, 2011). Greenpeace exist in Greenland has create hatred amongst Greenlanders because their action has cause a huge loses by stopping them on sealskin trading, and telling youngsters in town not to eat whale or seal, the food Inuits have lived off for hundreds of years (Moshiri, 2010). Again in 2010, Greenpeace once again attack on Greenland oil rig development which condemn by Greenlander Prime Minister Kuupit Kleist (refers to the textbox above), and damaging countrys economy by occupy drilling platform (Carrell, 2010). As understand, Greenpeace trying to protect the nature from deteriorated by the oil drilling. The case above has shows that the organisation has violated their principle of non-violent confrontation, finding solutions and informed debate about societys environmental choices (Greenpeace, 2010). This case is very similar to their condemnation on Papua New Guinea development where there is no fundamental respect for democratic principles when dealing with the situation in a wrongful action because it is not about informing the public about the danger of environmental impact but it creating public unrest. Besides that, there is no ethical relativity in this case. According to Gael McDonald (2010) saying that ethical relativism it driven by the recognition of historical, cultural and individual diversity and the principal supporters are those who have identified significant variations in moral customs around the world and in different social settings (McDonald, 2010). Based on Greenland case, Greenpeace should not condemn Greenlanders oil rig development and halting their sealskin export because it will ruin the country economic, and their forceful approach has infuriate Greenlanders where the organisation has no right to condemn their economic approach where most Greenlanders agreed upon the development of their oil rig reserve because it will reduce the dependency on Danish annual $500 million grant from the oil development (Moshiri, 2010). In addition, there is also no duty of care to resolve the problem in a less confronted approach.

grachi tiberius gaius rome Essay examples -- essays research papers f
THE GRACCHI Tiberius Sempronius Gracchus was bon in 163 B.C. and came from a distinguished family. His grandfather conquered Hannibal, his father brought the Celtiberian war successfully to a close, reduced Sardinia, and was elected consul for two terms and sensor for one. His mother Cornelia was a woman of wide-culture who employed Greek tutors to educate her sons, Tiberius and Gaius. Two tutors who influenced Tiberius at a young age were Diophanes, a teacher of oration and Blossius of Cumae, a philosopher. After taking part in the campaign of 146 BC, which ended with the destruction of Carthage, Tiberius was elected quaestor in 137. Travelling through Etruria, Tiberius saw large estates worked by slaves and noticed the absence of free peasants. It is said that Tiberius realized the need for reform while visiting this province on his way to Spain. There, Tiberius served in a war against Numantia under the consul Mancinus. After suffering numerous defeats in battle, Mancinus attempted to abandon camp. However the Numantines, realizing what was happening seized the camp before they could escape. Tiberius saved the Roman army from slaughter by securing a treaty with the Spaniards. When they returned to Rome, Tiberius was seen as a saviour and blame was placed on the incompetent generals who were handed back to the Spaniards for execution. Tiberius himself escaped judgement by the skin of his teeth. According to Plutarch, ââ¬ËIt would seemâ⬠¦that Scipio, who was then the greatest and most influential man at Rome helped to save themââ¬â¢ (1988, 159) There are a number of dominant motives for Gracchusââ¬â¢ want for reform. His knowledge of Greek political thought and practices allowed him to understand the needs and potential of the state, the Spanish campaign, slave revolts in Sicily, the increase in Romeââ¬â¢s unemployment rate and the impact the changing economy had on the republic. It doubtful that only one of these fuelled Gracchusââ¬â¢ desires for change, it is more likely a combination of many or all. When Tiberius began to speak out in politics he did not do so alone. He was backed by his father-in-law Appius Claudius Pulcher, who was Princeps Senatus and two others, Pontifex Mucius Scaevola and Pontifex licinius Crassus Mucianus. IN 133 Tiberius Gracchus was elected tribune. He proposed a ââ¬Ëlex agrariaââ¬â¢ which would make land owned by the state available for distribution ... ...ople. During Gaiusââ¬â¢ visit to Junonia to oversee the construction effort, rumours were spread in Rome by his opponents of the delay and failure of his new colony. Through these rumours, Gaius lost favour with the people. This can be seen due to his failure to get re-elected for a third tribunate in 121. As tribune Minucius Rufus proposed to repeal one of Gaiusââ¬â¢ bills, he gathered support. In a minor disturbance, a servant of consul Opimius was killed. The senate was forced to pass a resolution that consuls should see to it that the Republic came to no harm. Opimius summoned to arms senators and equites against Gaius and Flaccus who had occupied the Aventine hill. After failed negotiations they and their supporters were defeated and killed. It is said that the weight of their heads in gold was to be awarded to the man who brought Opimius the heads of Gaius and Flaccus. Once again political differences in Rome resulted in bloodshed and brought an end to the remaining Gracchi. BIBLIOGRAPHY H.H.

The God Of Small Things by Arundhati Roy Essay -- God Small Things Aru
The God Of Small Things by Arundhati Roy Before going into the theatre ââ¬Å"to see The Sound of Music for the third timeâ⬠(35), Estha ââ¬Å"[completes] his first adult assignmentâ⬠(93). He goes to the bathroom on his own, while Ammu, Baby and Rahel accompany each other to the ladies room. This little detail about going to use the restroom foreshadows another instance where Estha will be forced from being a child into manhood. Ammu tells Estha to ââ¬Å"shut UP!!â⬠(96) because he was singing along to the words of the movies. Instead of shutting up, he leaves the theatre on his own account, because ââ¬Å"he couldnââ¬â¢t helpâ⬠(96) but sing along to the words he knew. After completing his first adult assignment, his childlikeness comes out in having to sing the lyrics in ââ¬Å"a nunââ¬â¢s voiceâ⬠(96). He did not know that this act of immaturity, in acting his own age, he would be shoved into yet another adult assignment, something that he kept as a small thing, but ended up as a Big Thing inside him. The Orangedrink Lemondrink Man scolded Estha for ââ¬Å"[disturbing]â⬠(97) him with his song. As soon as he is done scolding him, his ââ¬Å"yellow piano keyâ⬠(97) teeth offered him a free drink. As Estha came, the Orangedrink Lemondrink Man already knew what he had in store for Estha. The Man asked him questions, and Estha, being a man and a child, had to answer. Where did he live? What did his family do? The Man ââ¬Å"handed Estha his penisâ⬠(98) and made Estha masturbate him while he drank his lemon drink, and he had to, because the Man ââ¬Å"knew where to find [him]â⬠(104). After the Man was done with Estha, he sent him back into the theatre. Estha knew from this time that he would be love a little less if anyone knew what he had done with the Orangedrink Lemondrink Man. So he told no one. But in his head, a conversation was taking place between himself and Baron von Trapp, the father in The Sound of Music. Would von Trapp love him even though he was not white? Even though he ââ¬Å"[blew] spit bubblesâ⬠¦[shivered] his legsâ⬠¦ held a strangersââ¬â¢ soo-soos?â⬠(101). Was he still acceptable to obtain a Babaââ¬â¢s love? He knew that it was ââ¬Å"out of the question. [He could not] love themâ⬠(102). No father could ever love him. They leave the theatre because Estha the child, Estha the man, is sick. When they exit the theatre, the Orangedrink Lemondrink Man smiles at Rahel and offers her candy. She goes toward him, and is... ...lowing it to be made into another myth or to be erased by the present. The time was ââ¬Å"paintedâ⬠on to the wrist-watch that was buried under the History House. When that watch was left to become one with the grass and the dirt, it captured many things. It made time stand still. It took away the desire to speak. This affected Ammu and Estha in everlasting ways. Ammu went mad before she died. Ammu treated Rahel as though she were still seven, when she was actually eleven, saying, ââ¬Å"It was as though [she] believed that if she refused to acknowledge the passage of time, if she willed it to stand still in the lives or her twins, it wouldâ⬠(152). Estha changed dramatically as well. When ââ¬Å"childhood tiptoed outâ⬠and ââ¬Å"silence slid in like a boltâ⬠(303), they went to where the watch was, buried with Ammuââ¬â¢s mind. In the ground of the History house, the time would remain at ââ¬Å"ten to twoâ⬠(121). Ten to two; two small people against ten big people. Rahel and Estha ââ¬Å"trapped inâ⬠¦ a storyâ⬠(224) against Mamachi, Baby, Chacko, Margret, Sophie, Ammu, Velutha, Kochu Maria, Pillai, and the Orangedrink Lemondrink Man. Ten. Ten to Two. Where the God of Small Things, ââ¬Å"if he fought he couldnââ¬â¢t winâ⬠(207).

freedol Noras Freedom in Ibsens A Dolls House Essay example -- A Do
Nora's Freedom in The Doll House à à à à à Nora is initially introduced as a macaroon-loving, naà ¯ve individual constantly trying to please her husband.à However, when the audience discovers that she borrowed the funds that allowed her and her husband to travel to Italy for a year in order to save Torvald from certain harm, Nora demonstrates that she is actually a much stronger character than originally portrayed.à However, the real problem lies with the way in which she burrowed the money.à In order to get the cash, Nora forged her father's signature.à As a result, she is in debt to the man who leant her the money, Nils Krogstad. à Within the context of modern times, Nora's crime appears almost daring and creative, rather than completely criminal (Egan 67).à In comparison, Torvald's reactions to Nora's crimes seem almost cruel and unimaginative.à When he scolds Nora's father for a similar failure to secure proper signatures and condemns Nils for doing the same, he appears to be an unsympathetic individual.à He scolds people and judges them for their actions without considering why the may have done what they did. à Furthermore, the household in which Nora and Torvald live in is completely patriarchal, again demonstrating Torvald's limited imagination.à He gives Nora very little power and very little credit, when she appears to be much more imaginative than him.à Within the house's walls, all items exist for one purpose: to entertain Torvald.à Also, Torvald appears to lack the understanding that other people may be interested in other things, and that there are people on this planet who should be considered within the same class as him.à à The play was initially seen as an attempt to express the conflict... ... Henrick Ibsen: A Biography.à Garden City: Doubleday, 1971. à The student may wish to begin the essay with the quote below: à Good grief, can't you understand?à The old man never existed; that was only something I'd dream up time and again whenever I was at my wits' end for money.à But it makes no difference now; the old fossil can go where he pleases for all I care; I don't need him or his will-because now I'm free.à Oh, how lovely to think of that, Kristine!à Carefree!à To now you're carefree, utterly carefree; to be able to romp and play with the children, ,and to keep up a beautiful,à charming home-everything just the way Torvald likes it!à à And think, spring is coming, with big blue skies.à Maybe we can travel a little then.à Maybe I'll see the ocean again.. Oh yes, it is so marvelous to live and be happy! à à à à à à à à à à à --Nora in The Doll House.
