A Lack of Tech-Friendly Policies Means US Could Loose Its Lead Essay Sample free essay sample
The article ââ¬Å"A Lack of Tech-Friendly Policies Means US Could Loose Its Leadâ⬠provides relevant treatment about deficiency of proper proficient inventions in the state. It is argued that the state strongly lacks proficient geographic expeditions. new in-migration workers policy and more low-cost instruction. The writer references that the US is a state with tremendous resources. venture capital and the best universities. but the state should move quicker to keep worldââ¬â¢s taking place in technological domain. I think that the article is really of import for countryââ¬â¢s policy because it highlights current jobs and challenges. Nowadays engineerings are fleetly developing in many Asiatic states. particularly in China. Japan and Korea. and. in my sentiment. the US authorities should pay more attending to policies which encourage and promote technological inventions and scientific geographic expeditions in the energetic field. Actually. the state has adept applied scientists to interchange information and proper resources to use.

I agree with the writer that ââ¬Å"innovation starts from educationâ⬠. and the fact that ââ¬Å"too many pupils are dropping out of school. and excessively few are analyzing math and scienceâ⬠is truly dissatisfactory for me. I think that making more occupations. actuating pupils to larn. and increasing productiveness will excite technological development of the state. The writer is really persuasive as he offers relevant grounds and claims of cardinal political figures to escalate the feeling and do people cognizant of bing jobs. However. I donââ¬â¢t like the thoughts of working out new atom bombs. Space missions. in my sentiment. are of import as they help to understand our universe better.

The Tempest by William Shakespeare
The Tempest by William Shakespeare The relationships between fathers and daughters are usually particular. This connection is greater when a father have to bring up a daughter himself. It is obvious that no matter how old a daughter is a father always considers her as a small girl who needs care and protection.Advertising We will write a custom essay sample on The Tempest by William Shakespeare specifically for you for only $16.05 $11/page Learn More The appearance of one more man near a lovely daughter is usually considered as the attempt to still the dearest person in the world, that is why many fathers are usually against their daughtersââ¬â¢ relationships with other men no matter how good these men are. The denial is the first reaction fathers usually experience and their desire to check a man is understood. One of the main conditions according to which a daughter is going to be protected in the future is the strong assuredness that a daughter is in good and loving hands, protected lik e under the fatherââ¬â¢s care. Reading the play The Tempest by William Shakespeare, it becomes obvious that the same situation is happening among Prospero, Miranda and Ferdinand. Starting the discussion with Prospero and Miranda it should be mentioned that living on the island, Prospero understands how cruel the surrounding world may be. However, Miranda is really naà ¯ve and cannot distract the simple problem from the real disaster. Taking care for a daughter, Prospero is ready to create the fake problems and put the intentions of loving Ferdinand under question just to make sure that the man is ready to fight for his daughter and to win in this battle. At the very beginning of the play Prospero says the following to Miranda, I have done nothing but I care of thee,Advertising Looking for essay on british literature? Let's see if we can help you!

This phrase directs the further relations between Prospero, Miranda and the men who surround her. Everything Miranda knows is the merit of her farther. Being educated, polite and well bread, Miranda is a great example of an ideal daughter and a wife. It seems that father is going to be glad when she meets a person with whom they are going to live together, however, everything is absolutely different. Trying to make sure that Miranda is going to be safe and protected, Prospero in interested in pleasing her at the island. Still, he could not predict the appearance of Ferdinand who spoiled all the dreams of the father. Each father wants their daughters to be happy, however, at the same time, many fathers are sure that their children are going to be near them all the time.Advertising We will write a custom essay sample on The T empest by William Shakespeare specifically for you for only $16.05 $11/page Learn More The appearance of Ferdinand on the island and the first scene where Miranda and Ferdinand meet each other seems too dangerous for Prospero. Prospero cannot trust Ferdinand and tries to check his intentions. Prospero understands that Miranda is going to fall in love with Ferdinand as there is no another way out. A girl has been at the island for the last 12 years (since she was 15) and the natural desire of a young woman to love and to be loved is essential. However, Prospero does not want Ferdinand to get such a great woman as his daughter for free, without battles. Prospero understands that being restricted from the whole world, Miranda is not going to reject Ferdinandââ¬â¢s courtship. At the same time considering his daughter as a great prize, too expensive and unique, Prospero uses his magic to force Ferdinand to suffer. Even though Miranda has never been fallen in love, sh e understands that she is ready to do anything for her lover, [I weep] at mine unworthiness, that dare not offer What I desire to give, and much less take What I shall die to want. But this is trifling, And all the more it seeks to hide itselfAdvertising Looking for essay on british literature? Let's see if we can help you!

If not, Iââ¬â¢ll die your maid. To be your fellow You may deny me, but Iââ¬â¢ll be your servant Whether you will or no (Shakespeare 60) The further dialogue is the expression of the feelings where two young people exchange the desire to be together ââ¬Å"a thousand thousandâ⬠hours (Shakespeare 60). Even though this scene presupposes that two lovers are not going to meet any difficulties, that these people are not going to suffer, Mirandaââ¬â¢s father thinks differently. The story of love discussed in the play is like any other love-story has to suffer greatly to have a happy end. Being able to control everything and everyone on the island, it is difficult to imagine that Prospero is not going to use an opportunity to create difficulties for the fiancà © if the bride is not ready (or is not taught) to create those. It is impossible to say w hether it is the desire to make sure that all the rules are followed as when people love each other they are to be together. It seems that the author of the pay intentionally creates the sarcastic situation. Lovers can be together without any difficulties, however, the usual estate of affairs is different and there is a person who can create the complications. Still, the lovers are predicted to be together. The author shows the reader that it is Prospero who unites two lovers to underline the fact that everything on the island is under his control. Therefore, it may be concluded that the romantic relationships between Miranda and Ferdinand are possible only because Mirandaââ¬â¢s father allows them. At the same time, looking at the situation from the perspective of the acknowledgeable audience, it becomes obvious that Prospero is exactly the person who has created additional circumstances on the way for loversââ¬â¢ union. Why is it necessary? Whether the desire to create the si tuation which usually appears is that great? Reading the final words Prospero expresses to the audience, it becomes obvious that Prospero believes himself the director of the destinies of people who surround him. Miranda and Ferdinandââ¬â¢s love is neither predicted nor directed by Prospero, that is why he wants to make sure that all the occasions which happen on the island (like it was before Ferdinand and his family arrived) are caused or controlled by him. ââ¬Å"Our revels now are ended. These our actorsâ⬠¦Ã¢â¬ (Shakespeare 82) are the final words in the play which support the idea of Prosperoââ¬â¢s desire to control the whole island with people there. Therefore, the love of two people sometimes depends not on the circumstances which appear, but on people who surround them as sometimes the desire to be the main person in the lives of others may put under question the positive intentions.

Tight Control in Beverage Operation Assignment Example | Topics and Well Written Essays - 500 words
Tight Control in Beverage Operation - Assignment Example Conversely, this has created a paradox in these arguments (R11). Therefore, the paper seeks to discuss three operational elements where tight control can affect customer satisfaction and operational ease and vice versa. Many organizations have policies and procedures that govern all its operations in service delivery to its customers. These policies and procedures ensure ease of operation and customer satisfaction. However, there may be elements of operation within a company where tight control affects customer satisfaction and the operational ease. For customer satisfaction, important operations elements must be put in place. However, in case of a tight control of these operations, both customer satisfaction, and operational ease may be affected. For instance, good service, right strategy application, and beverage expertise are good examples of operational practices that enhance a smooth operational ease. If these operational practices are taken care of appropriately, customer satisfaction would also be achieved (Slack & Stuart 28). The operational practice, therefore, improves efficiency and visibility hence enhancing profitability, competitive advantage, and customer service. Expertise in a beverage is an essential component that enhances the operational ease and customer satisfaction. For a beverage company to achieve these, a team of experts of beverage should be in charge of handling the business. Operations and supply chains needs should guide these operations. These include technology and software selection, network design for the supply chain, and management of the workforce. These strategies need to be regulated depending on the customer needs and expectations in order to maintain customer satisfaction (Tamime 24). However, if a tight policy control is put in place without considering the customer needs, the satisfaction of the customers may be affected.

Management Accounting - The 'Raw Material' cost as a 'Variable Cost' Essay
Management Accounting - The 'Raw Material' cost as a 'Variable Cost' - Essay Example The job responsibilities of financial accountants is to ensure that all financial transactions are recorded into the books of accounts, are valued appropriately, and all transactions are reflected in the statements. Generally Accepted Accounting Principles (GAAP) are used by financial accountants as a benchmark standard to develop financial statements (Wikipedia, 2007). Public companies are legally required to develop and publish financial statements. In contrast, Managerial Accounting focuses on the internal issues which are required by management to make informed decisions about business processes. These also provide the management with an insight into business functions' efficiency and effectiveness and provide valuable information about operations of the system of internal controls. The managerial accounting information is not required to be disclosed to public in contrast to the financial accounting reports; rather the reports produced by managerial accounting function are normally classified as 'confidential' and are for internal use only (Wikipedia, 2007). A few reports developed by managerial accounting function include inventory reports, product costi

Securing MANET From Routing Attacks
Securing MANET From Routing Attacks CHAPTER 3 RESEARCH METHODOLOGY 3.1 RESEARCH PROBLEM The increasing demand and utilization of wireless technology is making the need for more secure wireless networks. From the security viewpoint MANET is one of the most interesting research fields. A MANET is generally exposed to vulnerabilities due to its open medium, rapidly varying network topology, lack of centralized control and lack of clear line protection and it suffers from a wide range of security threats and attacks. Attacks can be introduced into all the layers of protocol stack however the attacks on the routing layer are most detrimental. The attacks on the routing layer can be either from the outside the network or can take place within the network. The attacks from outside of the network contain no authentication information and can be avoided by employing authentication techniques and cryptographic schemes. The most common insider attacks include blackhole, wormhole, selective forwarding, RREQ and hello flooding, Sybil, sink hole and so on. Insider attackers are more critical compared to the outsider attack as the insider knows the valuable information and holds the access rights. To solve this issue, security solutions have to be proposed in order to secure MANET. The goal of this thesis is to analyse the impact of blackhole, wormhole and flooding attack under on-demand routing protocols such as AODV and DSR and to propose possible countermeasures to thwart these attacks. 3.2 AIM AND OBJECTIVES The aim of this research work is to secure the MANET from various routing attacks in order to improve the performance of the network. To achieve this aim, the following objectives are formulated: To analyse the impact of blackhole, wormhole and flooding attack under AODV and DSR routing protocol To analyse packet delivery ratio and end-to-end delay in case of black hole, wormhole and flooding attack using AODV and DSR protocol and the results of AODV and DSR are compared to evaluate which of these protocols are more susceptible to these kind of attacks. To develop defence mechanisms against blackhole, worm hole and flooding attack under AODV and DSR protocol. 3.3 SCOPE OF THE THESIS There exists various routing attacks in MANET such as blackhole, wormhole, Sybil, selective forwarding and flooding attack and so on. This research work considers only blackhole, wormhole and flooding attack and its impact on on-demand routing protocols such as AODV and DSR is analysed. Efficient detection techniques have been developed to mitigate the effect of these attacks against AODV and DSR routing protocol. The performance of these routing protocols using the detection techniques are evaluated in terms of packet delivery ratio and end-to-end delay. 3.4 SYSTEM ARCHITECTURE This research focuses on blackhole, wormhole and flooding attacks on AODV and DSR protocol. The architecture of the proposed system is given in Figure 3.1. Efficient techniques such as MSBD and ABM, MCHOP and CDCF, MCLUT and TSPS has been developed to detect blackhole, wormhole and flooding attacks under AODV protocol and techniques such as ABM, CDCF and TSPS have been developed to mitigate against blackhole, wormhole and flooding attacks under DSR protocol. The proposed techniques detect these attacks effectively and provide a secure path. Figure 3.1 An Overview Of Attacks On MANET Routing Protocol And Their Detection Techniques 3.5 DETECTION TECHNIQUES AGAINST BLACKHOLE, WORMHOLE AND FLOODING ATTACKS 3.5.1 MultiShared Bandwidth Approach for Blackhole Attack Detection The AODV protocol is vulnerable to the well-known black hole attack. In this thesis, the multishared approach is designed to prevent any alterations in the default operation of either the intermediate nodes or the destination nodes. Here, watchdog mechanism is incorporated with MultiShared Bandwidth (MSBD) approach to detect misbehaviour or abnormal activity of a node, once an abnormal activity is observed MSBD is initiated. The MSBD converts the data into 16 bit and further splits the 16 bit data into multiple shares. When multishared data is received by a node it checks the bandwidth of neighbouring nodes to transmit the data. Then it chooses the nodes with highest bandwidth along the path and sends the data through these selected paths. 3.5.2 MCHOP-A Cluster based Approach for Wormhole Attack Detection In AODV routing protocol, the intruder will attack the network using the attack like wormhole during the route discovery stage. A cluster based algorithm has been proposed to detect a wormhole attack on AODV routing protocol. In this approach, the network is partitioned into several clusters based on density based clustering algorithm. Here, AODV protocol is modified in such manner that it detects the wormhole attack based on the hop count comparison and time taken to receive RREP packets. The cluster head is responsible for adding certain fields such as hop count, destination address to the RREQ packet and it broadcasts it to the other cluster head in the network. Whenever the intermediate node receives the RREQ packets, it sends an ACK to the source node with hop count information and broadcasts it to the destination node. The destination node then unicasts the RREP to the source node utilizing the reverse path. The RREP is then validated by source node using the hop count informat ion and time taken for receiving the packet. 3.5.3 MCLUT- Clustering Approach for Flooding Attack Detection The proposed MCLUT approach is used to detect the flooding attack node by enabling the clustering approach and calculating the threshold value of each node in the cluster. Here dynamic threshold value is used. The threshold value is estimated based on the queue length of a node and its neighbour in the cluster. If a node does not satisfy the threshold value then it is considered as an intruder. Once the cluster head confirms that the node is intruder it then broadcast the message to other nodes to isolate the node from the cluster and the suspicious node is kept in observation. 3.5.4 Anomaly based Behaviour Monitoring Algorithm for Black hole Attack Detection under AODV and DSR protocol The proposed Anomaly based Behaviour Monitoring (ABM) algorithm detects blackhole attack on AODV and DSR protocol. This technique periodically checks and verifies whether the number of packets disseminated between source and destination are equal. Through this comparison, the source node could detect the presence of black hole node. 3.5.5 Channel Detection and Cut Defalconin algorithm for Wormhole Attack Detection on AODV and DSR Channel Detection and Cut Defalconin (CDCF) algorithm is proposed to detect wormhole attack on DSR and AODV protocol. This method detects a wormhole attack in the network based on the threshold limit and then provides a new route to forward the packet from source to destination. The threshold value is determined based on Round Trip Time (RTT) and a delay per hop (DPH) is calculated based on the RTT, while forwarding packet from source to destination with the malicious nodes, its take less Round Trip Time (RTT) to forward the packets to the destination, when forwarding packet from source to the destination without any malicious node attack, it takes more RRT to forward the packets to the destination. If the DPH of a node is smaller than all other nodes, then it indicates the wormhole attack presence. 3.5.6Transmission Sequence Based Packet Scanner Algorithm for Flooding Attack Detection on DSR and AODV. Flooding is a Denial of Service (Dos) that is designed to bring down the service of the network by flooding it with huge volume of traffic. Transmission Sequence based Packet Scanner (TSPS) technique has been proposed to detect flooding attack on DSR and AODV. The TSPS identifies the presence of flooding attack based on source id, empty packet, number of hops and transmission sequence number.

Learning and Decisions Essay
Decisions can be difficult to make because they have such an impact on life. Have you ever had to make an important decision? Making decisions is very important in life. Decisions are what make the world go around. I have made many decisions in my life. One that has changed the high school part of my life was whether or not I would play varsity hockey my freshman year. Before the decision I had made a list of the ââ¬Å"pros and consâ⬠. For instance I didnââ¬â¢t like the fact that I would get less playing time, although in the long run I would learn more and become a better hockey player. If I were to look back on my decision I definitely wouldnââ¬â¢t change it for a second. Perhaps I might do some things different, but overall I improved my skills a lot and now use to the pace of the game. For this reason during the off season I was provided with more opportunities to play with older players to keep improving my skills. Some decisions can make or break a friendship. Specifically at the beginning of this school year I told myself I was going to change my personality, and become a nicer guy. Compared to staying the same arrogant kid I have been able to acquire more friends and more respect. Particularly I choose to begin this decision because I felt like an idiot. In truth I figured I would be able to focus better in school because I wouldnââ¬â¢t be getting in trouble. All things considered Iââ¬â¢m glad I made this decision. I am a lot happier person, and I hope to stick with it. With the way the economy is, I feel very fortunate to have a job. During the past two summers I made the decision to get a job. The alternative decision for me was to be sitting at home doing nothing, or out at work gaining in income, and a responsible attitude. Specifically I also choose this decision thinking it would keep me out of trouble. T was constantly exhausted but learned a lot of responsibility. Now after the decision if I were to look back on it I donââ¬â¢t regret it. Decisions can be difficult to make because they have such an impact on life. The decisions I talked about were all ones that I would not change. These decisions have changed my life and I have learned a lot from them. In conclusion I have learned a lot from the decisions I have made, whether or not I regret them I look back on them as learning experiences.

Mao
Twentieth century has brought many revolutions on the face of the world. The century have seen a list of dictatorships, some constructive and others destructive. Leader principle, has however, been recognized as a basis of dictatorship. Chinese Revolution has been one of these mega revolutions of the twentieth century. The ultimate objective of the revolution was to bring China out of the ââ¬Ëliberal bourgeoisieââ¬â¢, and the revolution was launched by the communist party under the supervison of great Mao Zedong. While discussiong the Chinese revolution, the great leap forward and the immediate infulence of the revlotuion, the role that Mao Zedong played as a leader cannot be ignored. Maoââ¬â¢s career examplifies the leader principle in a variety of styles. Being trained in a Chinese classics and later receiving the modern education, Zedong has deeeply observed the oppresive conditions of the society and aimed to nip the adversities in the bud. The reason behind the fact that people of China regard him as a symbol is his philosophy. The development of Maoist ideology was based on the foreign philosophical doctrines of Karl Marx and Vladimir Lenin. Mao, however, sinified Marxism in an attempt to ensure unrealistic future growth (Cheek, Timothy). Though, following the Marxist school of thought for the betterment of the economic structure of the country Maoââ¬â¢s belief of dictatorship has also some great influences on his career. Every Communist must grasp the truth: Political power grows out of the barrel of a gun (Zedong Mao). This statement of Mao clearly mentions that, in order to bring a change in status quo, the importance of political power cannot be denied, and the political power lies in leader principle. Though Maoââ¬â¢s career has mostly been highlighted with reference to the great Chinese Revolution, but his efforts date from the foundation of Chinese Communist Party, then Mao during the Second World War, and of course the prominent figure of the Chinese Revolution. Maoââ¬â¢s personality following the leader principle during the Second World War has been highlighted mostly because of the policies of Chiang Kai Shek, the opposition leader who consumed all of his energies to fight the communists, instead of the invading Japanese forces. This gave a plus point to Mao in fact. After this Maoââ¬â¢s efforts to bring the economic equilibrium in the country with special reference to the Chinese Revolution, has emerged in the history as a milestone. Though the revolution has been aimed to nip the roots of socialism, and was certainly in the favor of masses, but it still faces some critiques. According to Timothy Cheek, The Great Leap Forward was a product of Maoââ¬â¢s utopian visions at the Beidaihe Conference in August 1958 (Cheek 160). The Great Leap Forward was in fact the ultimate outcome of Maoââ¬â¢s Marxist view. It resulted in the boost of industries on one hand pushing the production levels higher, but on the other hands the peasantry and the agriculture sector got neglected very badly, as most of the farmers and the peasants left the occupation and started making steel. Cheek further says that ââ¬Ëpeople simply believed in Maoââ¬â¢ (Cheek xiv). This statement of Cheek is of contradictory nature. On one hand it gives an impression that, the policies of Mao have been much attractive for the people, and on the other hand it may reflect the essence of dictatorship, where by people have no other option. The twenty seven years of rule made Mao a different image in the history, combination of achievements and a bit flaws. One more important element in the career of Mao Zedong was the personality cult in 1968. This gave Mao the ultimate political power and according to some researches, he sent his disloyal official to the country side to work in the labour camps. In the same time Zedong ordered to the young intellectuals to move to the countryside in order to educate the masses at villages. This effort of Zedong has largely been appreciated among the Chinese and that is the reason they gave him a God-like status. The young intellectuals though ordered to move to the villages, were allowed to get back to the cities later. The Cultural Revolution, peopleââ¬â¢s access to criticize the social and cultural institutions, and the economic and the political development in China has largely been associated with Zedongââ¬â¢s principle leadership. His thought became the central operative guide for the people of China; they ignored the traditional art and ideas while praising his efforts. Though being so much praised, there are some other views as well. Cheek at one place says ââ¬ËJiang and David Ashley purport that Maoââ¬â¢s revolutionary achievements allowed him to continue to command immense respect (Cheek, xiv). This may be true to some extent, but in general, if a leader moulds the society and the economy in a more productive way with a specific acceleration, the respect among masses is the only and biggest reward for him. Maoââ¬â¢s career entitled with a long list of achievements has not only led him to have the respect and a God like status, but to have his name as a great leader of the history as well. Itââ¬â¢s reported that, on Maoââ¬â¢s death people have been found crying on the streets. Some experts rate Maoââ¬â¢s era with 70% success and 30% failure. So 70% success is not bad at all. And the leader leading the nation towards this success if given the God-like status is not a command respect in my opinion. Maoââ¬â¢s era entitled with the social and economic achievements, though criticized to a limited extent, makes him the best leader in the history of China. And while comparing the other dictatorships in the world during the twentieth century, heââ¬â¢s been the most respected and successful one. à Work Cited: 1- Cheek, Timothy. [2002] (2002).
