Cry, Our Beloved Country Essays - Cry, The Beloved Country, Jarvis

Cry, Our Beloved Country Cry the beloved country, by alan paton, is a book which tells the story of how james jarvis, a wealthy estate owner who, because of his own busy life, had to learn of the social degradation in south africa through the death of his only son. If arthur jarvis had never been killed, james jarvis would never have been educated by his sons writings, and stephen kumalo. When we first meet james jarvis, he knows little of his sons life. He doesn't know his son was on a kind of a mission(p. 140), And this is why when harrison says,...we're scared stiff at the moment in johannesburg.( p. 140) James is sort of surprised and says,of crime?(p. 140). Talking to harrison taught stephen about the crime in the city, and the next morning he learns about his son. One of the first things that james learns of his son, and his views, he learns in arthurs' room. In reading his writings, james finds that arthur would have risked anything to help other people, and ended up doing just that. James finds that his son was well researched on the problems of their society, and was interested in helping the development of the social structure in south africa. From the pictures of jesus and lincoln on his wall, james discovered the admiration arthur had for these two men. These were men of action, who showed love for their friends, and at the same time, their enemies. These two men suffered and died for their beliefs, as did arthur in a way, this is showing arthurs' father what a great man his son was by comparison, and similarity to others. This revelation shows arthurs concern for humanity. After the discovery of his sons views through all of his writings, james begins to realize the problem, and starts to think of the problems of others before his own. In this aspect, james begins to remind the reader of oscar shindler. This is so because shindler was one who at one time hated jews, but as he began to understand them, he thuoght of their troubles and how his wealth could save them. Much like shindler, jarvis helps the minority. Following his sons death and the acquaintance of stephen, james donates 1000 pounds to the african boys club. Jarvis is not just giving gifts in memory of his son, or just to give, but giving those who need help ways to help themselves. When james gave the money to the club, he didn't just decide to give it to them, but knew that if he gave it, the club would use it to improve the countrys' condition. In all of his donations, james uses this subtle method to emancipate the blacks. A way to help his son taught him. Using his sons views again, jam es decides to do something about kumalos' village, which is falling apart. This task is a fairly large one , and james does this in steps. He first provides milk for the village kids, who only have warm water to drink, and then he builds a church. The reason he decides to build a church is that when he is in ndotsheni it begins to rain, and he and stephen take shelter in the church, which leaks and is in need of repair. The rain in ndotsheni is a bit of foreshadowing of hope for the village, and maybe of what is to come. Through james' education, we learn the similarities between mr. Jarvis and kumalo. When we first meet jarvis, the setting is much the same as when we met stephen. They both live in the farming areas of south africa, and they share the love for the land, and what is in their lives. They each are married with one son who they know nothing about, and both are forced to come to terms with the guilt of the whites by the same occurance. After they both lose their sons, they have a need to understand them, although all that is left are the memories. They each learn of the problems in south africa through their sons, and after the realization, they both try to do something to improve

A Color Purple essays

A Color Purple essays The characters relational identity towards one another in The Color Purple played a significant role in the development of each character. Specifically, the relationships between Celie and the other characters begin to define her and change her throughout the novel. The relationship between Celie and Shug Avery is the focus from early on in the book as well as the relationship between Celie and her sister, Nettie. Once Netties letters are found some of the focus returns back towards Nettie. Celie and Nettie are sisters that are close, with Nettie being the younger one. Early on in the book Nettie serves as a stronger personality than Celie even though Nettie is much younger than her. After marrying Mr. , Celie takes Nettie into her home after Celie runs away from their step father. After some failed sexual advances by Mr. _ towards Nettie, Nettie is forced to leave Celie behind also. This leaves Celie alone with Mr. _ and makes Celie basically powerless. She is essentially seen as someone who is very passive in her confrontations, especially with Mr. _, as well as other men. However, Celie shows she knows that others see her as a powerless object when she tells Sofia, Celies large dominant friend who marries Celies stepson, she is jealous of her strong, self-defensive personality. I like Sofia, but she dont act like me at all. If she talking when Harpo and Mr. _ come in the room she keep right on. Nettie tells Celie that she will write her but eventually the letters get snatched up by Mr. _ and he never tells Celie about them. Celie assumes Nettie is dead because she has not heard from her since she left. One day Shug Avery notices a few letters that Mr. _ has been holding back. With them all being hidden in Mr. _ trunk Celie, with the h elp of Shug Avery, regains her sense of self-identity by learning about her prior fa...

Global strategy Essay Example | Topics and Well Written Essays - 250 words

Global strategy - Essay Example Competitive rivalry in UK supermarkets are driven by advertising battles, sales promotion campaigns, price competition, introducing new products, provision of warranties and guarantees and after sales services improvements. Threats attached to new entrance are minimal as product differentiation enables existing firms to build good brand image culminating to strong customer loyalty (Onsman, 2003, p.111). The market is controlled by Tesco, Sainsburys, ASDA and Safeway with nationwide branches and overseas high risks investing hence barriers for new entrance based on large capital constraints and difficulty to access distribution channel with new channels hard to establish. Aldi’s trio-principle; consistency, simplicity and responsibility makes it thrive. Aldi’s DNA and culture is driven by cost-effectiveness based on lower staffing and payroll cost but higher wages than rivals hence high capability in-store levels than rivals driven by investment in sophisticated till systems focusing on staff training (Onsman, 2003, p.122). It operates limited opening hours to avoid keeping shoppers for longer hours in stores and refutes add on facilities to remain cost-effective. Aldi’s secrecy of success lies on invisible strategies (Secret Culture) such as understanding essential defining features lying beneath the surface; unwritten cultural rules, values and standards hence Aldi’s competitive

Customer Relationship Management Essay Example | Topics and Well Written Essays - 3750 words

Customer Relationship Management - Essay Example Customer relationship management also serves to evaluate the consumer as a means of providing them with the products which would be most suited to their demographic or psychographic profile (Coravue Inc., 2007). Generally this is accomplished by reviewing browsing habits stored in mass databases or reviewing comments left by customers on company websites. In the bricks-and-mortar sales environment, evaluating customer habits can sometimes be as easy as reviewing a credit card statement or sales history over a period of days or weeks. However, who really cares about customer relationship management' PepsiCo should, as there is little evidence that the company maintains a focus on CRM other than through brand-building exercises which appear to give the impression that PepsiCo products are more commodities than tools for building customer satisfaction and loyalty. Evidence suggests that PepsiCo, despite their extended, global reach and wide variety of subsidiaries and brand varieties, requires significant adjustment to existing CRM policies. This paper assesses the overall importance of customer relationship management whilst applying CRM literature to the current marketing environment at PepsiCo. Recommendations for improvements in CRM focus at the firm will also be proposed. Technological develo... elopments are generally the key to successful CRM programmes, allowing for business communications regarding CRM focus to be distributed as well as maintaining an adequate database of consumer-related information. The Internet, additionally, allows organisations to use real-time customer interaction, through a series of integrated communications messages, to support the brand's image (Turner, 2008). From the technological perspective, customer relationship management is about having the software support necessary to extend the brand/company experience into new areas of streamlined payment systems or interactive, entertaining product websites. PepsiCo is quite competent in its interactive marketing focus, developing a wide variety of contest websites, interactive product design websites (allowing consumers to interact in a virtual design environment), and countless others. For instance, the company utilised a promotional incentive by printing various codes on the tops of its Pepsi brand products, allowing customers to visit the corresponding website to win various prizes (Harwood, 2006). In this particular campaign, PepsiCo received 15 million entries, which suggests that the campaign was a tremendous success. It would be a likely assessment that much of the registration information regarding consumers was stored in a database in the event of requiring information for other promotional offers or incentives. Some might argue that promotional literature and interactive contest websites would not be included in CRM, however in terms of the successes of the Pepsi-Cola brand, these types of promotional activities are creating connection with consumer lifestyle and with the company itself. One need only visit a legitimate PepsiCo product website to witness an enormous

Quantum Optical Model Nonintegrability Quantum Fluctuation

Quantum Optical Model Nonintegrability Quantum Fluctuation Nonintegrability and quantum fluctuations in a quantum optical model Nilakantha Mehera and S. Sivakumarb Abstract Integrability in quantum theory has been defined in more than one ways. Recently, Braak suggested that a quantum system is integrable relating the number of parameters required to specify the eigenstates and the number degrees of freedom (both discrete and continuous). It is argued that the dependence of uncertainty product of suitable operators on the atom-field interaction strength is distinctly different for the integrable and nonintegrable cases. These studies indicate that the uncertainty product is able to identify the nonintegrable systems from the integrable ones in the context of this new definition. Introduction A classical dynamical system with n degrees of freedom (DOF) is integrable, Liouvillean integrable to be precise, if there are equal number of suitable constants of motion (COM) that have vanishing Poisson bracket among themselves and with the Hamiltonian1.. Otherwise, the system is nonintegrable. While this definition is based on a sound mathematical footing, the situation in quantum dynamics is not very clear, essentially arising from the difficulty in defining or identifying DOF in quantum theory2. One possibility is define integrablity by the existence of sufficient number of observables which commute with the Hamiltonian and pair-wise commute among themselves. However, this is wrought with difficulties as it may not be possible to arrive at classical limits of some quantum systems. One such example is the case of a single two-level atom interacting with a single mode of the electromagnetic field. The former is a discrete DOF (finite dimensional Hilbert space) and the later is a continuous DOF (infinite dimensional Hilbert space). While the continuous DOF, namely, the electromagnetic field, has a proper classical limit, the two-level atom does not have a suitable classical limit. According to a new definition introduced by Braak, a system is integrable if the number of parameters required to specify the eigenstates of the Hamiltonian is equal to the sum of the number of discrete DOF and continuous DOF2. This definition does not involve the existence of constants of motion, though all such cases are covered by this definition. In this new definition of integrability, some of the nonintegrable systems based on the Liouvillean definition become integrable. A simple example of such a system is the Rabi model describing the interaction between a two-level atom and a single mode of the electromagnetic field with Hamiltonian3; (1) Here, are Pauli matrices, is the atomic transition frequency, () denote the annihilation (creation) operators of field with frequency. is the atom-field coupling constant. This Hamiltonian has only one COM, namely itself. Since there are two DOF, the field and the two-level atom, the Hamiltonian is nonintegrable in the sense of Liouville. However, exploiting the parity symmetry in , the system has been shown to be integrable2. Another interesting case is the rotating wave approximation of , yielding the well known Jaynes-Cummings model4,5: (2) This Hamiltonian has two COM, the Hamiltonian itself and the operator for the number of excitations . Existence of these two COMs renders the Hamiltonian integrable. The eigenstates are labelled by two parameters,an integer n corresponding to the number of excitations and the total energy. Also, both the Hamiltonians and exhibit level-crossings of the eigenvalues as the interaction strength g is varied, which is an indication that the models are integrable2. Level-crossing refers to the phenomenon where in the eigenvalues depend on the interaction strength g in such a way that the eigenvalues corresponding to two different eigenstates become degenerate at a specific values of g and reverse their order for other values of g. Nonintegrable Model : An interesting modification to to make it nonintegrable is to break the à ¯Ã‚ Ã… ¡2 symmetry by adding and this leads to; (3) Within the scope of the Braak’s definition of integrability, this model is integrable only when ÃŽ µ is an integral multiple of ω/2. This is also borne out by the existence of level crossings as shown in Fig.1. This criterion is sufficient for nonintegrability. We assume resonance . For the results presented here, it is assumed that =1 and ω=1. In Fig. 1, the absence or presence of level-crossing indicates respectively the nonintegrability or integrability of the Hamiltonian . Fig.1.Energy level (En) as a function of g for different à °Ã‚ Ã…“â‚ ¬. Level crossing occurs if à °Ã‚ Ã…“â‚ ¬=0 and 0.5 indicating integrability. No level crossing if à °Ã‚ Ã…“â‚ ¬=0.3, indicating nonintegrability. Inset shows larger view of level crossing. A pertinent question in this context is to know those features that distinguish a nonintegrable atom-field system from an integrable one. One answer to this query appears to be that uncertainty product of a pair of suitably defined operators show markedly different characteristics. Since the system is nonintegrable, it is formidable to construct an analytical solution. Therefore, extensive numerical experimentations have been carried out and the results are presented here which support the claim stated above. Nonintegrability being a feature of the Hamiltonian, it is natural to expect that the eigenstates carry signatures revealing this feature. To explore this, we define two self-adjoint operators of the two-level atom, , , where () is the atomic raising (lowering) operator. The commutation relation implies that the value of the product of uncertainties lies between 0 and 1/2. The uncertainty relation of above operators is . whereis expectation value in any eigenstate. In Fig. 2, the uncertainty product is plotted as a function of the atom-field interaction strength for different values of à °Ã‚ Ã…“â‚ ¬: à °Ã‚ Ã…“â‚ ¬= 0, 0.5 and 1.0 corresponding to the integrable case and a few other values of à °Ã‚ Ã…“â‚ ¬ corresponding to nonintegrable case. It is seen that as the parameter g is increases, the uncertainty product attains its maximum allowed value of  ½ for the integrable cases. On the other hand, for the nonintegrable cases the uncertainty product falls below the limit of  ½. In order to establish that the uncertainty product is very sensitive to the nature of the the integrable and nonintegrable cases, the plots corresponding to values of à °Ã‚ Ã…“â‚ ¬ very close to integrable cases have been chosen. Fig.2.Uncertainty product () as a function of the atom-field coupling constant g. Different plots correspond to different values of à °Ã‚ Ã…“â‚ ¬: integrable cases: à °Ã‚ Ã…“â‚ ¬=0, 0.5 and 1.0, nonintegrable cases: à °Ã‚ Ã…“â‚ ¬=-0.01,0.01, 0.49,0.51,0.2 and 0.4. In any plot, the uncertainty is plotted for the eingenstates corresponding to the first fifty eigenvalues. For instance, in the second row in Fig. 2, the sudden change in the nature of uncertainty product as à °Ã‚ Ã…“â‚ ¬ assumes values 0.49 (nonintegrable), 0.5 (integrable) and 0.51 (nonintegrable) respectively are shown. In order to bring out the features more clearly, the probability distribution of the uncertainty products in different eigenstates are shown in Fig 3 corresponding to the respective figures in Fig. 2. The sharply peaked probability distribution indicates integrability. Fig.3. Probability distribution of the uncertainty product for all the eigenstates for a particular value of g, chosen to be 1.2 here. Any higher value of g yields the same results. Summary Identification of nonintegrability in an interacting atom-field system is possible by the concentration of uncertainty product near a particular value as the atom-field interaction strength is increased. This feature seems to be related closely to the nonintegrability, also supported the absence of level crossings. This feature has been found to be able to identify nonintegrability in many other models that have been studied. In essence, suitable uncertainty product is able to identify nonintegrability, which is often difficult to establish analytically or numerically. Nevertheless, our analyses raise some important questions for which answers are to be found: Is it possible to arrive at the existence of this feature using only the definition of nonintegrability used here? Given a Hamiltonian, how to identify the correct observables whose uncertainty product will concentrate as the interaction strength is increased? How to extend this idea if the number of atoms is larger? References: M.V. Berry and M. Tabor, Proc. R. Soc. A 356, 375 (1977). D.Braak, Phys.Rev.Lett. 107, 100401(2011). I. I. Rabi, Phys.

Pro Legalization of Euthanasia Essay -- Argument for Euthanasia

I am poured out like water, and all my bones are out of joint, my heart is like wax, it is melted within my breast, my mouth is dried up like a potsherd, and my tongue sticks to my jaws, you lay me in the dust of death (Psalm 22) Some might say euthanasia is wrong, it is murder, it is an inhumane act. But is it not inhumane to see another person’s unbearable suffering and not release them when they long to be released? Is it not cruel to watch a person in a vegetative state, with no brainwaves showing, fed by a machine, â€Å"breathing† with the help of a machine and not let them be liberated from their pain? Prolonging one’s suffering when an easier, more painless way out is possible is not â€Å"the right thing to do†. Giving the person the choice of release is. Euthanasia is. What is euthanasia? The basic definition of euthanasia is the practice of ending a life so as to release an individual from a painful, incurable disease or intolerable suffering. There are said to be two types of euthanasia: passive and active. Passive euthanasia is â€Å"stopping (or not starting) some treatment which allows a person to die, the persons condition causes his or her death† (Mackinnon, 12). An example would be â€Å"withdrawing a respirator or feeding tube† (Landau, 80). â€Å"Passive euthanasia is a brutal death. Allowing someone to starve to death and die of thirst, the way we do now, is barbaric†. â€Å"That’s what the Nazis did in the concentration camps† (quoted in Manipulating Life, 33). Active euthanasia on the other hand is an act of â€Å"merciful killing†.
