Cybercrime evolved from a return of one billion dollars in 2007 to over one trillion dollars in 2009 ( Imperva. 2010 ) . Attackers design malicious applications utilizing free interfaces with societal media and shooting their ain codifications into topographic points that have loopholes and mistakes ( Westervelt. 2010 ) . Zero-Day FeatsThese feats take advantage of exposures that the package seller does non cognize about Lashkar-e-Taiba entirely forestall. Hackers formulate different fluctuations of Malware to take advantage of these countries before the Developers can piece and protect against these exposures ( Wikipedia. 2013 ) . Oracle’s Java is an illustration of an application that is vulnerable. Their latest spot JAVA 7 Update 11 is in topographic point to forestall up to fifty of these exposures as it merely late experienced some of these feats. Many users are disenabling this application in a Browser scene. comparing it to â€Å"Kissing a black rat. in London. during the pestilence. † As stated in the Inquirer ( Neal. 2013 ) . Session ChopingRecently. there has been an addition in the highjacking of Sessionss and therefore doing a Hacker the ability to take over a User’s session while they are telling something and being able to go on minutess on a vulnerable Web application. These minutess are ensuing in the development of resources of the Web site and of the Credit Card Providers for these users after the User’s reaches their responsible per centum rapidly. The Hacker uses their methods to work found exposures or have a User chink on an application that allows them to take control undetected while the user continues their shopping. Once the User marks off and leaves the dealing it purportedly closes its session. the Hacker suspends the dealing until the seashore is clear and so continues undetected. ( Imperva. 2012b ) . E-Mail Coup detatElectronic mails can be hacked by assorted methods. and no 1 is immune. Recently even Presidents G. H. and G. W.

Ezzz Essays - Logic Families, Digital Electronics, Free Essays Ezzz Discussion: A logic gate performs a logical operation on one or more logic inputs and produces a single logic output. The logic is called Boolean logic and is most commonly found indigital circuits. Logic gates are primarily implemented electronically using diodes or transistors, but can also be constructed using electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. The simplest form of electronic logic is diode logic. A Digital Logic Gate is an electronic device that makes logical decisions based on the different combinations of digital signals present on its inputs. A digital logic gate may have more than one input but only has one digital output. Standard commercially available digital logic gates are available in two basic families or forms, TTL which stands for Transistor-Transistor Logic such as the 7400 series, andCMOS which stands for Complementary Metal-Oxide-Silicon which is the 4000 series of chips. This notation of TTL o r CMOS refers to the logic technology used to manufacture the integrated circuit, (IC) or a "chip" as it is more commonly called.

Women in camps Essay Example | Topics and Well Written Essays - 500 words

Women in camps - Essay Example Jewish women had to suffer from brutal torture for being female. They were kept naked, and were beaten. Their heads were shaven off. Pregnant women and those who had little children were not selected to work, and were left to die. The Nazis conducted medical experiments on them forcefully. They were given involuntary sterilizations and forced abortions. â€Å"At least 40,000 people were forcefully sterilized, with 5,500 women dying after being sterilized,† states Avraham (2014, par.2). Although Nazis had passed legislation against any sort of sexual relations with Jewish women, yet they would rape them on regular basis after abducting them from streets. They were subjected to forced labor and sexual abuse. Some of them were also sent to Nazi brothels forcefully where they were subjected to rape and sexual assault. Men and women were forced into Philippine concentration camps during the Philippine-American war in early 1900s. They were promised that they would be provided food and security, but they suffered from the worst genocide and torture. Women suffered from starvation and disease. â€Å"By the end of the war, it was reported that 27,927 Boers (of whom 26,251 were women and children, of which 22,074 were children under 16) had died of starvation, disease and exposure† (AngloBoerWar.com, 2014, par.4). Malaria, cholera and dysentery were the main killers. Where males were buried alive and suffocated to death using water cure torture, women were left to die of disease and malnutrition. The Cuban Holocaust saw genocide in Cuban concentration camps in 1896-97 during the Spanish-American war. â€Å"The concentration camps contained more women, children, and the aged†¦they also died of malnutrition and disease,† states Perez (2006, p.197). Women sent the male members of their families to the war willingly despite knowing that they would be left without protection. The Spanish had claimed that they would look after them

Part 2 - Health promotion edit - Essay Example Indeed, homosexuals are too vulnerable to be abused by their families, particularity because of the customs and traditions of Lebanese society, according to which people keep living with their families even when they are adult. Once might think that only women are subject to, honor crimes, but homosexuals are also victims of such crimes. Even though different charges and penalties which are issued on imposed on homosexuals and the government attempts to frustrate them, they are still fighting for their rights performing a remarkable achievements supporting LGBT on the social and political class. Indeed, many NGO’s, which call for human rights, placed the issue of homosexuality on their top list. MIRSAD is a governmental and private organization that is concerned with the issues of human rights as they aim to spread awareness on the Lebanese society in order to create democracy and equality. In one of the cases the MIRSAD defended protested against the police operation as they arrested and integrated with the owner of the one of the LGBT website. As a result the MIRSAD was not able to achieve successes as their director was also arrested for protesting (10). However, the organization did not stop supporting LGBT and human right issues. Another organization is Helem, which aim to spread awareness about sexual d isease such as HIV and STIs. Indeed, Helem mostly tend to focus on the right and health of LGBT. In fact, Helem state that their belief is to â€Å"consistently promoted the idea that knowledge is the key to openness, tolerance and acceptance† by educating Lebanese society about homosexuality and their rights. In addition, Helem educates the public and policymakers through offering real data, arranging effective dialogues, events, workshops, lectures and media. Furthermore, with the rejection of the public to LGBT individuals, they created their own private internment environments hidden from the public eyes. Besides the

Nurturing the Childrens Spirituality in the Learning Process Essay

Nurturing the Childrens Spirituality in the Learning Process - Essay Example In such a way they are able to maintain compassionate and balance learning process to make them pro-active in school activities. Through this, they are expected to enjoy social cohesion and harmony within and outside of the school. De Souza (2004) asserted that Values Education and Clarification have been considered by the state as significant to be integrated into the curriculum to teach learners moral values as an inspirational tool in defining their good relationship with the rest of humanity and creation. Since the 1960s, moral values are a significant parcel in the formation of the learners’ affective domains to integrate their emotional, attitudinal, values and beliefs’ constructions (De Souza, 2004). Experts believed that values and moral are derivatives of peoples’ emotive sense and, thus, are not viewed as relevant in their cognitive being (De Souza, 2004). Hence, it’s this dichotomy of human existence that made it confusing and difficult to arrive at a common understanding of values of education (De Souza, 2004). It’s in this context that experts dealt the dualism of educational philosophy: language and practice (De Souza, 2004). They adopted an educational pattern for cognitive development and for values education to develop a standard behavior and intelligence of learners and to nurture that sense of commitment among individuals based on virtue and values (De Souza, 2004; Lambert, 2003, Noddings, 2010). Some psychologists observed that this has been considered as an effective tool since historical experiences proved that the integration of values in improving learners’ intellectual pursuits made people resilient in times of recession, conflicts, and social upheavals and during wars (Cacioppe & Edwards, 2005; Glendinning, 2005; Gross, 2004).

Improving Resource Allocation for Data Center Overbooking

Improving Resource Allocation for Data Center Overbooking M.Ponmani Bharathi, C.Sindhuja, S.Vaishnavi, Ms.A.Judith Arockia Gladies Abstract Overbooking becomes feasible because user applications tend to overestimate their resources and requirements, that tends to utilize only a fraction of the allocated resources. Overbooking has to be carefully planned in order not to impact application performance. Resource utilization and Data centres utilization can be used in this overbooking scheduler. Data send can send from sources to destination via node. Resource utilization and allocated capacity can be increased by 50% with acceptable performance degradation. Fuzzy logic functions are used to check each overbooking decisions and estimate it. Changing the acceptable level of risk is depending on the current status of the cloud data centres. The suggested approach is extensively evaluated using a combination of simulations and experiments executing real cloud applications with real-life available workloads. Our results show a 50% increment at both resource utilization and capacity allocated with acceptable performance degradati on and more stable resource utilization over time. Keywords: Proportional Integral Derivative (PID), Mitigation algorithm, Greedy algorithm 1. Introduction Authors Data set for overbooking levels. It is collections of some Services and work loading data. The data that represents the collection of fields that will be returned when the data set query runs on the data source. Dataset fields represent the data from a data connection. A field can represent either numeric or non-numeric data. Main features provided by cloud is elasticity, allows users to dynamically adjust resources allocations depending on their current needs. The objective is to make an efficient use of available resources, overestimating the required capacity results in poor resource utilization. Factors contributing to lower the Data Centre Utilization: cloud provides predefined VM Sizes, which have fixed amount of CPU, memory Disk Etc. A set of distributed PID controllers are implemented to avoid performance degradation and to increase and keep the utilization evenly distributed among the servers. Overbooking addresses the utilization problems that cloud data centres face due to the elastic nature of cloud services. Overbooking has to be carefully planned in order not to impact application performance. It present an overbooking framework that performs admission control decisions based on fuzzy logic risk assessments of each incoming service deployment request. If delay beyond slack on critical path is initiated, then the completion time of the project may get delayed. Resource levelling is a method for smoothing a schedule that attempts to minimize the fluctuations in requirements for resources when the project completion time is fixed. Users are usually bad at estimating the requirements of their applications. This low resource utilization is a big concern for cloud data centred providers as data centres consume l ot of energy and are being used in a rather inefficient way. Energy consumption does not decrease linearly with resource usage. One way cloud providers can mitigate these resource utilization problems is by overbooking. The overbooking techniques always expose the infrastructure to a risk of resource congestion upon unexpected situations and consequently to SLA violations. This leads to: Overestimating the required capacity results in poor resource utilization. Lower income from consumers. The contrary, underestimating may lead to performance degradation and/or crashes. Overbooking is to address the utilization problems that cloud data centres face due to the elastic nature of cloud services. Overbooking has to be carefully planned in order not to impact application performance. It present an overbooking framework that performs admission control decisions based on fuzzy logic risk assessments of each incoming service deployment request. A set of distributed PID controllers are implemented to avoid performance degradation and to increase and keep the utilization evenly distributed among the servers. Overbooking within cloud data centres to increase resource utilization in a safe and balanced way. The cloud paradigm also introduces new obstacles for efficient resource management. The very large scale and multi-tenant nature of cloud infrastructures offers great potential for efficient multiplexing of different services. Our initial work on this problem include scheduling for better server utilization and admission control for capacity planning, getting an initial understanding of the overbooking problem and the risk evaluation, respectively. Cloud applications do not use the same amount of hardware resources all the time. This low resource utilization is a big concern for cloud data centred providers as data centres consume lot of energy and are being used in a rather inefficient way. One way cloud providers can mitigate these resource utilization problems is by overbooking. Figure 1 Overbooking Fuzzy Risk Assessment 2. Mitigation Algorithm for Reducing Service Level Mitigation method is used to avoid sun expected misbehaviors, such as reducing the service level of some services to avoid performance degradation. This Algorithm is used to collocate, reducing the performance degradation when overbooking. This algorithm also clear traffics for data center overbooking utilization. Proportional Integral Derivative (PID) controller is a generic control loop feedback mechanism. PID calculates the differences between the measured and desired set points attempts to minimize it by reading the control input.PID involves three parameter, Present error(P), Accumulated error(I), Prediction of error may occur (D). 1. Data Collection Dataset for overbooking levels is a collection of some Services and work loading data. The data that representing the collection of fields that will return when the dataset queries runs on the data source. Dataset fields represent the data from a data connection. A field can represent either numeric or non-numeric data. 2. Overbooking Overbooking is techniques used as a solution to poor resource utilization in cloud data centres. Overbooking is mainly used to handle the data centred resource utilization problems and overbooking. An implemented an autonomic overbooking framework. An autonomic framework that provides better application performance, avoiding over passing total capacity at any of the dimensions will be provided. 3. Resources Utilizations It determines the shortest project schedule with the limited resources available. 4. Schedule with collocation It presents a greedy approach that perform traffic-aware VM placement to increase the rate of accepted requests. It avoid repeating poor performance and to increase the chances of good collocations. VMs are suitable to be collocated for improved utilization and stable performance. 5. Prediction method The prediction step calculates a rough approximation of the desired quantity. The corrector step refines the initial approximation using another means. Overbooking system as well as admission control techniques when dealing with elastic services need insight in future resource usage. Service requirements to avoid performance degradation due to overloaded physical resources. 3. Distribution of PID Controller PID controlled this fact motivates the use of feedback to adjust the level of risk that the overbooking system is willing to face over time. We also evaluate the distributed controller approach when the data centre size is reduced to 128 cores. Furthermore, choosing an acceptable risk threshold has an impact on data centred utilization and performance. High thresholds result in higher utilization but the expense of exposing the system to performance degradation, whilst using lower values leads to lower but safer resource utilization. When overbooking CPU and I/O capacity, and a more realistic approach for the memory. The rationale for this is that problems resulting from CPU or I/O congestion are less critical than the ones coming from running out of memory. Therefore, the different risk degrees presented can be combined according to the situation, considered capacity dimensions, knowledge about the incoming service, etc. The risk assessment module gets no feedback about the current status and behaviour of the system, the current workload mixture, the data centre size, etc. In order to address this issue, we propose here a control theory approach that dynamically (re)adjusts risk thresholds depending on the system behaviour and the desired utilization n levels, allowing the admission control to learn over time depending on current system behaviour. PID Controller works properly if the performance is measured at the data centre level, obtaining a smooth utilization fluctuations (close enough to the target one) for each congested capacity dimension. However, the utilization of each server may vary from the accumulated utilization – even after applying load balancing techniques. This effect cannot be totally avoided as load imbalance is also caused by the current workload characteristics. To reduce load imbalance we propose a distributed controller approach where each physical server has its own PID controllers, one for each capacity dimension. 4. Related Techniques Mathematical models for SaaS providers to satisfy customers by leasing Cloud resources from multiple IaaS providers. It proposes three innovative admission control and scheduling algorithms for profit maximization by minimizing cost and maximizing customer satisfaction level. It demonstrates effectiveness of the proposed models and algorithms through an extended evaluation study by varying customer and provider side parameters to analyze which solution suits best in which scenario to maximize SaaS providers profit using actual IaaS data from Amazon and Go Grid. An extensive evaluation to study and analyze which solution suits best in which scenario to maximize SaaS provider’s profit. In-house hosting can increase administration and maintenance costs whereas renting from an IaaS provider can impact the service quality due to its variable performance. Dynamic consolidation of virtual machines (VMs) is an effective way to improve the utilization of resources and energy efficiency in cloud data centres. The problem of host overload detection by maximizing the mean inter migration time under the specified QoS goal based on a Markov chain model. Through simulations with workload traces from more than a thousand Planet Lab VMs, we show that our approach outperforms the best benchmark algorithm and provides approximately 88 percent of the performance of the optimal offline algorithm. The data center efficiency is been improved and more enterprises are been to consolidate the existing system. All system resources and centralizing resource management allow increasing overall utilization and lowering management costs. Server consolidation has emerged as a promising technique to reduce the data centre energy cost. We also present a distinguished analysis of an enterprise server workload from the perspective of consolidation and finding characteristics for it. Then observing a significant inherent for power savings if consolidation is performed using off-peak values for application demand. An implementation of the methodologies in a consolidation planning tool and provide a comprehensive evaluation study of the proposed methodologies. The size applications by an off-peak metric and place correlated applications together; there is a high risk of SLA capacity violation. If consolidation is performed by reserving the maximum utilization for each application, the application may require capacity equal to the size of its current entitlements. As per the size of the cloud increases, the anticipation that all workloads paralyze scale up to their maximum demands. In this observation multiplexing is allowed to access cloud resources among multiple workloads, resource information have been improved. Hosting virtualized loads such that available physical capacity is smaller than the sum of maximal demands of the workloads is referred to as over-commit or over-subscription. It computationally and storage efficiently, while maintaining sufficient accuracy. It is simple method of estimating total effective nominal demand of a cloud and uses it for capacity sizing and placement reservation plan that is compliant with SLA. 5. Conclusion Overbooking has to be carefully planned in order not to impact application performance. A set of distributed PID controllers are implemented to avoid performance degradation and to increase and keep the utilization evenly distributed among the servers. Feedback control is used to adapt the level of overbooking (risk threshold) that the cloud data centre has tolerating capacity. The utilization technique of data centre is not only increased in overall but also harmonized across hardware capacity dimensions and servers. A set of distributed PID controllers are implemented to avoid performance degradation and to increase and keep the utilization evenly distributed among the servers. References [1] A. Ali-Eldin, J.

Theravadan Buddhism Essay -- essays research papers

Theravadan Buddhism Throughout history there have been numerous religions and theologies that men and women have entrusted their lives and ways of living to. One of the most intriguing is that of Buddhism. The great Buddha referred to his way as the middle way, and he, as the "Enlightened One" began the teachings of the religion with his first five Ascetics who he shows his middle way. This great occasion is the start to what will be known as Theravadan Buddhism. Although Theravadan Buddhism would later be seen as the "small vehicle," it provides the first idea of the doctrine anatman or having no-self that shapes the ideas of every Buddhist today. Theravadan Buddhism which means "The teaching of the elders," is the teaching of the Buddha in its true traditional form. After attaining enlightenment under the Bohdi tree, the Buddha returns to five ascetic monks he had been associated with previously. He taught them the essential parts of Buddhism which include the vital Four Noble Truths. These teachings were taught by monks, and they give the fundamental truths on which the religion was founded. These are the Four Noble Truths: (1) all life is inevitably filled with sorrow; (2) sorrow is directly due to craving; (3) sorrow can only be stopped by stopping the craving; and (4) this can be done only by disciplined and moral conduct with meditation led by the Buddhist monk. These truths show that the Buddhists saw all things as transient, and being transient there is no eternal Self or soul, hence anatman or no true self. While the Theravadan Buddhist practiced the idea of anatman, there were other movements that practiced the idea of atman or true self. The Upanishadic movement, which started about 300 years before the Theravadan practice, revolves around a story of a boy who Yama tells there is a self in everyone. This true self or atman is covered up by the illusion of an individual. As this way of thinking was being taught, people began to uprise and question if religion is worth it. This leads to many ascetic movements in which people leave their homes to be scavengers. Because this could be done by any it began to get very popular. The many ascetic movements gave rise to many different individual movements... ...low, I feel that all of these ways of life are flawed. In most of the religions only the higher classes can reach the supreme way of life. The regular people are stuck, and they can only help the monks or Brahmans to attain their goal. This seems very unfair even if they are producing good karma. In the Vedic religion the Shudras don't even have the option of studying the holy text. They have no chance of gaining entrance to another level of being until their next life. Theravadan belief of the being no true self is all together mind boggling. If there was no self then how can karma pass from one existence to another. It can't. Each period in time has new ways of thinking and viewing the world. India has been a place of many movements in the field of religion. These early ideas and practices of Theravadan monks can be seen as one of the many religious ideas of the past, that has in some places lasted to the present day. As is the case with all religion, it will be subject to scrutiny, questioning, and slander. While many may not see the Theravadan way of anatman as being right or even sane, it is their way of life and they should be respected for it.

Michel et Augustin Essay

In 1978, Ben Cohen and Jerry Greenfield launched Ben & Jerry’s, an ice-cream brand made from milk products and 100% natural ingredients. Two young students, Augustin Paluel-Marmont and Michel de Rovira have decided to take example from this mythical brand (as well as Innocent), and launch their own brand of biscuits: Michel et Augustin! The story of their brand building is truly a successful adventure, which gives by the way a whole meaning and a huge capital of sympathy to their brands, what the two friends are far from hiding, on the contrary†¦ They wanted to recreate the delicious biscuits of their â€Å"grandma† by gathering all the best and natural ingredients. But their positioning is not only about tradition and nostalgia, on the contrary. Admittedly, they use souvenirs as Proust and its famous Madeleines to hit their target – the 18-25 years old living in city – but want to go beyond tradition. Indeed they claim a return of quality, but in a modern, original and more often crazy way! Values & Identity: a new way of defining itself => put joy of life and fun at base corporate value Michel et Augustin have created a new way of claiming values, which contributes totally to their original brand identity, which could seem not really serious at first sight. The brand value corresponds fundamentally to both friends’ values. And no need to try to understand them, if you do not know the story of these two young entrepreneurs. Michel was consultant in strategy and Augustin was in Air France Marketing. The both young men were on tracks to build a great career. But they decided to drop everything to make their dreams come true, to live their own passion! Indeed, they did not recognize themselves in the traditional corporate value. They wanted something more, something different, whit less constraints and more joy of life! Then, they launched in 2004 their own brand of biscuits and milk products, surrounded by those unconventional values, converging to one motto, one mutual dream: â€Å"Make the world smile†. And those values, incarnated in the good mood are far from being only a marketing communication. Beyond their headquarter which is called â€Å"the Bananeraie†, their slogan â€Å"Les trublions du bon gout† and their â€Å"crazy† and unexpected packaging, the atmosphere of the firm is truly defined by this central value. Both co-directors claim the same value, as simplicity, enjoy life, solidarity, sense of the effort, in their communication than in the place of work. Thus, the 31 workers of the â€Å"Bananeraie† form the â€Å"tribu†, Michel is the â€Å"calife†, Augustin â€Å"the Vizir†, and Nicolas, the accounting manager, the â€Å"conteur de bonnes nouvelles†. Good news is announced by ringing the bell in the office†¦ In short, Michel et Augstin advocates new values, based on sincerity and fun, which are totally conveyed within their management. Their website conveys as well their will of differentiation. As example (below), they denounce on their website the usual cliche on food product benefits. Instead of giving these controversial and usual reasons to like their products, they put forward the simplest and most basic reason to like them: because they are good and fun! And all this convivial values are aimed to one objective: build a deep and true relationship with their customer. Make the world smile† is then far easier when the values are supported by the brand and the employees themselves! Events, website and packaging become next the ambassadors of those values among the customers! One question remains, is it possible to claim fun, in communication as well as in workplace while being serious in his job? Indeed, as they are facing an increasing growth, with all responsibilities and issues coming by, it will be more and more complicated to keep such a spirit of work†¦ Packaging => An instrumental way to convey their values They do not play the cart of nostalgia, on the contrary! The brand wants to build a great complicity with its customers, in a fun and simple way, without any hypocrisy. Then, the name â€Å"Michel et Augustin† and the logo (drawn in a caricature style) are made to convey an enthusiastic impression, far away from usual institutional statements. Thus, for more interactivity, they go until giving their email addresses and their phone number on the back pack of products! We can then say, without exaggerating, that the four criteria of a good packaging are fulfilled. Indeed, their packaging is fully: Attractive thanks to its strong originality (story of the brand told in a fun way on the back pack, attractive colors which are well standing out in shelf – with the violet for example – ) * Functional, really easy to open, does not take too much place * Easy to produce and inexpensive * Coherent with the brand value (cf. the phone number, best example of the brand humor and the will of nearness with its customers) Communication => a â€Å"street† Marketing aligned with their spirit The art of the â€Å"story telling† they stress so much is obviously one of their priorities in their marketing strategy. Although this brand counts from now one among strong and solid alimentary firms, it can really not compete with Danone or Nestle from a communication budget point of view. Indeed, it is not possible for this launching brand to dispense large amoung in TV advertising, or huge communication campaign. It has to be clever about it, and find creative and cheap way to become famous. And Michel et Augustin has precisely found the right way to do so, by cultivating this story telling art, mixed with their crazy and bluffing behavior. The both creators acknowledge that their product packaging is their best weapon to reach and target the customers. Yet, they did succeed to create the buzz with unexpected events. For example, they benefited from the huge media retransmission for the â€Å"Entrepreneurs Salon† by putting their yoghourt bottle at the Bill Gates‘ table. Thanks to its initiative, they were exposed in front of the â€Å"whole† world, as the bottle with the cow was filmed with Gates drinking it! Best inexpensive advertising ever!

Free Essays on The Good Earth

The Good Earth, written by Pearl S. Buck, shows a real, but fictitious account of a Chinese peasant’s rise from the depths of the poor to become one of the most powerful men in the entire province. The story follows Wang Lung from his early adult days to his final days on his deathbed. The novel goes from showing Wang Lung’s family begging for money on the curb to survive to each member in the household being able to have their own personal slave. It is captivating tale and has a lot to offer to a westerner to find out about the Chinese way of life. The purpose of the novel is to show the different types of relationships that the Chinese have and their values to a westerner that may read the book. China has always been a very confined country that has kept to itself and blocked out the outside world. The Chinese, especially of yesteryear, do not have much contact with foreign influences. This has created a large problem with the outside world, especially the western world, as to the misunderstanding of why the Chinese do the things they do. Not only that, but also to inform the reader of the Chinese relationships and cultural views of these relationships that develop. The author tries to argue, through her writing, that although the Chinese relationships and hierarchical dominance system may not be normal, or even moral, to a western world reader their actions are accepted in their society. Pearl S. Buck does not draw these relationships for the reader to pass judgement on, but rather to understand why the Chinese do as they do . Pearl S. Buck shows these relationships in three major themes. The most significant relationship is the one of Wang Lung and his land. The second most major one that is developed was the relationship of Wang Lung and the females that are in his life (O-lan, his wife, and Lotus Flower, his concubine). The last relationship is more on a social scale. It seems that the opinion of how others perceive him is ...
