Edgar Allan Poes The Cask of Amontillado

The Cask of Amontillado is one of the best known works of Edgar Allan Poe. This is a tale woven together through the use of lies and smooth words coming out from its main character and narrator.Advertising We will write a custom essay sample on Edgar Allan Poe’s The Cask of Amontillado specifically for you for only $16.05 $11/page Learn More The short story is interesting in the sense that all the information about the characters and the events that transpired that day came only from one source (Poe, p.1). Without remorse Montressor recounted how he deceived his friend Fortunato and led him to a trap that would kill him. It is therefore fitting to use characterization as an element to support the theme of betrayal. The theme of the story is betrayal. Montressor said that he was a friend of Fortunato and yet he plotted his murder. The elaborate scheme was revealed by the murderer himself when he gave away clues as to how he has planned the event be forehand and that it was not spontaneous act. Betrayal is the theme most evident in the story because Montressor was able to deceive his friend Fortunato. He played on his weakness. The pride of Fortunato was his downfall but it could never have been exploited until Montressor played the part of a good friend. Fortunato was an unsuspecting prey led to a deadly trap. The betrayal was perfectly set-up because of the personal qualities of Montressor. This is why Edgar Allan Poe’s characterization is the most important element of this short story. Without the brilliant characterization of Montressor the story cannot stand on its own and the readers would not be convinced that a betrayal of such magnitude is possible. The author was able to paint the picture of a cold-blooded killer capable of deceiving a friend. He was able to do this by allowing Montressor to be the narrator and the only source of information regarding the other elements of the story. Although the revelation of the character of Montressor was done indirectly, the fact that he was also the narrator of the story enabled readers to have access to his thoughts and feelings. By doing so the author was able to reveal a great deal of information regarding the foul mind of Montressor. At the same time wary readers can see how the plot to kill Fortunato evolved from an insult, to a grudge and then finally to premeditated murder. The characterization of Montressor also made it clear why the murderer succeeded and why he was able to commit the perfect crime in the sense that no one would know that he was the culprit.Advertising Looking for essay on american literature?

He had foresight to kill his friend at the height of the carnival because he knew that Fortunato wou ld be drunk. He also knew that it is the only time of the year that he could wear a mask without drawing suspicion. He could also then cover his face to prevent witnesses from identifying the man who was with Fortunato the last time he was seen alive. Conclusion The most dominant theme of the story is betrayal. The challenge for the author was to convince the readers that a powerful and influential man like Fortunato can be easily led to a trap. In this regard the author had to expertly use characterization to explain the motives of the killer and why he had the capability to commit a terrible crime. The characterization of Montressor also gave readers access to his thoughts and feelings therefore clarifying that he was intent to murder and betray his friend. Work Cited Poe, Edgar Allan.

mcclelland vs. grant essays

mcclelland vs. grant essays George McClellan and Ulysess S. Grant were two of the Civil Wars most prominent Northern generals. In this essay I will describe the two generals and provide brief details on the battles they were acquainted with. George McClellan was a US Military Academy graduate with an exemplary record as a cadet. In 1857 he resigned his commission to enter the rapidly expanding railroad business, where he quickly demonstrated outstanding ability. McClellan, appointed by Lincoln, was made commander of the main union army named the Army of the Potomac, after having proved himself a reliable commander of the Ohio troops. He immediately began drilling the disorganized and demoralized regiments into a reliable fighting force. He is described as to have been very well liked by his soldiers. His biggest weakness was his speed, or lack thereof. On one occasion Lincoln said if McClellan did not intent to use the Army of the Potomac he (Lincoln) would like to borrow it for a few days to see what he could do with it. (pg. 55) One example of McClellans slow tactics, however, persistence, were shown in early March of 1862. His plan consisted of maneuvering his army farther down the Chesapeake Bay in order to seize the Confederate capital. His plan faced an obstacle. The Virginia, a Confederate ship, attacked and almost shattered the union blockade. McClellan insisted that the Virginia be put our of commission before be began operations. (pg. 67) The Virginia eventually set sail back to the Norfolk harbor after four hours of engagement. In late March, although Lincoln urged him to move forth McClelland laid deliberate siege to Yorktown and allowed Confederate troops to stretch across the lower peninsula of Virginia. This delayed the advance for almost a month. McClellan thought that there were many more troops then there really were, mainly because his chief ...

Consumer behaviour Essay Example | Topics and Well Written Essays - 500 words - 3

Consumer behaviour - Essay Example These products have been grouped together depending on the type of decision rules that consumers would adopt while purchasing them Consumers will exhibit habitual/routine response behaviour while buying these products. In such cases, the consumer recognizes a problem and resorts primarily on internal search only, i.e. relies on his long-term memory. The internal search throws out a single solution, i.e. the most preferred brand which is purchased by the customer. There is thus low level of consumer involvement in such cases. Consumers typically demonstrate routine buying behaviour in case of low priced products that are frequently purchased. Consumers will resort to limited problem solving (LPS) decision rules while purchasing an aftershave lotion or taking carpeting decisions. Under LPS, consumers resort to some amount of external search in addition to internal search. They tend to consider a few alternatives before selecting a particular brand. Products involved in LPS arouse mild interest and curiosity. Consumers also resort to a little post purchase evaluation in such cases. Consumers will resort to extensive problem solving while purchasing luxury cars. They indulge in extensive information search which is followed by a complex evaluation of multiple alternatives. This process entails a thorough post purchase evaluation in such cases. Consumers use the extensive problem solving decision rules in case of infrequently purchased, very highly priced products. Typically such products carry a high symbolic meaning and have high social visibility. There are numerous features like focus, film format, lenses, timers, preview button, viewfinder, light meters, shutter controls etc. that can be considered while purchasing a 35mm camera. I find that the following attributes are relevant and must be kept in mind while making the purchase decision for a 35 mm camera; Shutter Speeds, Flash Sync, Autofocus,

Key Military Strategic-leader Competencies Essay

Key Military Strategic-leader Competencies - Essay Example At different stages of one’s career, an individual has to exhibit certain set of skills and qualities, which make him, stand out like nobody else. He has to portray the best of his character and bring out what is not present in the rest of the populace. He has to lead by example, a thing which people of present times usually lack and which is not that easily found in our society. Similarly, at the top level within military it is very significant to have a clear mind whereby the person can think way beyond his understanding as well as ask of his army to carry out his commands with astuteness and wisdom. Needless to say, a leader at a senior position within the military has to understand that he is the ultimate boss and without his proper vision and goals, there can be no other person to fill the void which would be created if his thinking and mindset are just not there in the right place . There have been many a number of individuals who have had exceptional talents, both in the field of sports as well as a number of other arenas of life but here we will focus on the role of leaders within the military and that too on very strategic positions . These people have ascended on the ladder of success with sheer hard work and commitment, which in its essence, is the key to attain and achieve success and fame.

Tracks Covering in Penetration Testing

Tracks Covering in Penetration Testing Er. Ramesh Narwal Er. Gaurav Gupta Abstract After completing attack, covering tracks is the next step in penetration testing. In tracks covering after completing attack we will return to each exploited system to erase tracks and clean up all footprints we left behind. Tracks covering is important because it gives clue to forensics analyst or Intrusion Detection System (IDS). Sometimes it’s difficult to hide all tracks but an attacker can manipulate the system to confuse the examiner and make it almost impossible to identify the extent of the attacker. In this research paper we describe all of the methods used in tracks covering and their future scope. Keywords: Exploit, Payload, Vulnerability Assessment, Penetration Testing, Track Covering Introduction Penetration testing is nowadays an important organisation security testing method. Penetration testing is also known as Pentesting. Main objective of penetration testing is to identify the security threats in networks, systems, servers and applications. Penetration testing consists of various phases which we discuss in overview of penetration testing. After gaining administrative access on a system or server, attacker first task is to cover their tracks to prevent detection of his current and past presence in the system. An attacker or intruder may also try to remove evidence of their identity or activities on the system to prevent tracing of their identity or location by authorities. To prevent himself an attacker usually erases all error messages, alerts or security events that have been logged. Overview of Penetration Testing Penetration Testing used for validation and effectiveness of security protections and controls of an organisation. It reduce an organisation’s expenditure on IT security by identifying an remediating vulnerabilities or loopholes. It provides preventive steps that can prevent upcoming exploitation. Penetration testing phases Pre-engagement Interactions Intelligence Gathering Threat Modeling Vulnerability Analysis Exploitation Post Exploitation Covering Tracks Reporting Pre-engagement Interactions Planning is the first step in pre-engagement. During this phase scope, goal and terms of the penetration test is finalised with the client. Target and methods of planned attacks are also finalised in this phase. Intelligence Gathering This is most important phase if we miss something here we might miss an entire opportunity of attack. All information regarding target is gathered by using social media networks, google hacking and other methods. Our primary goal during this phase to gain accurate information about target without revealing our presence, to learn how organisation operates and to determine the best entry point. Threat Modeling The information acquired in intelligence gathering phase used in this phase to identify existing vulnerabilities on the target system. In threat modelling, we determine the most effective attack methods, the information type we need and how attack can be implemented at an organisation. Vulnerability Analysis Vulnerability is loophole or weakness in the system, network or product by using which can compromise it. After identification of most effective attack method, we consider how we can access the target. During this phase we combine information acquired in previous phases and use that information to find out most effective attack. Port and Vulnerability scans are performe in this phase and all data is also gathered from previous phases. Exploitation Exploit is a code which allows an attacker to take advantage of the flaw or vulnerability within system, application or service. We must perform exploit only when we are sure that the particular exploit will be successful. May be unforeseen protective measures might be on the target that inhibit a particular exploit. Before trigger a vulnerability we must sure that the system is vulnerable. Our exploit must do proper clean-up after execution at compromised system and must not cause the compromised system to grow into unstable state. Given below figure shows some system shutdown prompt at compromised windows machine due to without proper clean-up of exploit after execution. After successful exploitation the compromised system is under the control of an attacker. Many times attacker or penetration tester need to alter the compromised or breached systems to attain privilege escalation. Post Exploitation Payload is actual code which executed on the compromised system after exploitation. Post Exploitation phase begins after compromised one or more systems. In this phase penetration tester identifies critical infrastructure, targets specific systems, targets information and data that values most and that must be attempted to secure. In Post Exploitation while attacking systems we should take time to understand what the system do and their different user roles. Every tester and attacker generally spend time in compromised system to understand the information he have and how he can take benefit from that information. After gaining access of one system an attacker can access other systems in that network by using compromised as a staging point. This method is known as pivoting. Sometimes attackers creates backdoor into the compromised system to regain access of the system in the future Covering Tracks In the previous phases penetration tester or attacker often made significant changes to the compromised systems to exploit the sytems or to gain administrative rights. This is the final stage in penetration test in which an attack clears all the changes made by himself in the compromised systems and returns the system and all compromised hosts to the precise configurations as they are before conducting penetration test. Reporting All of the information like vulnerability reports, diagrams and exploitation results generated during penetration testing must be deleted after handover to the client. If any information is not deleted it should be in the knowledge of client and mentioned in the technical report which is generated after penetration testing. Reporting is the last phase in penetration test in which penetration tester organise available data and related result sets into report and present that report to the client. This report is highly confidential which have all the results of penetration tests like vulnerabilities list in the organisation systems, networks or products and recommendations to solve these problems related to the security of the organisation assets, which helps organisation in stopping future attacks. How to cover tracks To compromise system successfully an attacker need to be stealthy and avoid detection by various security systems like firewalls, Intrusion detection systems (IDS). System administrators and other security personals uses similar techniques to identify malicious activities, so it’s very important for attacker to be remains undetected. A system administrator can examine processes and log files to check malicious activities. There are various challenges which are faced by a penetration tester after successfully compromise of target system. Now we describe various problem faced by a penetration tester in covering tracks Manipulating Log Files Data To manipulate log files data an attacker must have nice knowledge of commonly used operating systems. An attacker must aware of two types of log files system generated and application generated. Penetraion tester or attacker have two options when manipulating log data first one is to delete entire log and second one is to modify the content of the log file. After deleting entire log an attacker there is surety of undetectability. But there is drawback of deletion of entire log is detection. Second option an attacker have to manipulation of log files data within the log files so that system administrator is not able to notice attacker presence in the system. But sometimes if attacker removal of so much information make gap between logs files makes it noticeable. Log Files Management in Various System Main purpose of log files in various operating systems is to check health and state of operating system, to detect malicious activity, to analysis system if something bad happens(system troubleshooting). Here we show locations of log files in commonly used operating systems Windows, Linux/Unix, Mac. Windows In windows log files or stored in event viewer, which is easy to find simply search event viewer and run it. Event viewer is simply look like the figure as given below, where we can see all log files of the system and applications. Figure : Log Files Managements in Windows Linux/Unix In mainly all linux and unix operating systems log files are stored in the /var/log directory. Mainly system log files are hidden in linux and unix operating systems to see complete list of log files from shell simply type ls –l /var/log/ command in shell. In the below figure we show log files in BackTrack linux operating system Figure : Log Files Management in Linux/Unix Mac To get or access log files in MAC operating system simply open finder and select â€Å"Go to Folder† in the Go menu. Type in /Library/Logs and hit Enter here you get the screen like as given in figure which contains all log files. Figure : Log Files Management in Mac OS X To manipulation of log files data an attacker must have root privileges. Challenges in Manipulation of Log Files If the system administrator configures its system to transfer all log files on the remote server time to time, in that case an attacker or penetration tester can only stop log files transfer process except it they have no other way. Hiding Files Various Tools for Covering Tracks There are so many to compromise a system but after compromising the system the attack must need to cover their tracks because each and every activity that attacker can do is stored or recorded by the system. Every system have different way to record the activity that occurs in the system. Every attacker must covers their tracks that are recorded by the system so that no one can identify him.

Motivation and Manipulation in Julius Caesar Essay -- William Shakespe

In Julius Caesar, Shakespeare illuminates the themes of human motivation and manipulation. He examines the relationship between actions and motivations, cause and effect, and word and deed, using the symbols of hands and hearts. Throughout the play, the characters Brutus and Marc Antony express their different understandings of this relationship rhetorically. In his 1953 film interpretation, Joseph L. Mankiewicz demonstrates these characters’ understanding through both the play’s original dialogue and his own interpolated action. It is interesting to see the different effects of spoken rhetoric, as we experience it in the play, and the visual rhetoric of the film. The play itself complicates matters of motivation and therefore does not answer the question of blame. When reading one character, the audience feels connected with their point of view, and when reading the other, they are made to feel unsure about their initial opinion. In the end, it is nearly impossible t o discover the characters’ inner motives, and it is therefore difficult to place blame on one or the other. However, Mankiewicz visually presents the complex relationship between these two symbols and in doing so, he creates a more sympathetic persona for Brutus than the one in the play. He focuses on the hands as a symbol of unity, love, and friendship, and where characters use hands for evil acts, he is quick to juxtapose the actions of hands from the motivations of the heart. While Shakespeare uses this juxtaposition to merely complicate the matter without solving it, Mankiewicz uses it to simplify the question. For Mankiewicz, Brutus’ involvement in the murder of Caesar, does not wholly reflect his character, and the audience is made to see a more human, vulne... ...wn in the play. In Brutus’ words, â€Å"Th’ abuse of greatness is when it disjoins remorse from power,† and in that instance, the film shows Antony’s abuse of authority (2.1.18-19). Because Antony believes that the hands’ actions and the heart’s motivations cannot be separated, his language demonstrates this belief, and he acts accordingly. While Brutus may act maliciously at times, he believes that hands and hearts are not always inextricably linked and therefore, that is especially true of his evil actions. Though Shakespeare may the leave the audience in doubt, Mankiewicz does not avoid blame and suggests that the exclusive joining of hands and hearts disjoins compassion from power and leads to true butchery.

School Uniforms Are a Necessity

Reading books is better than TV! Reading books is better than TV! Reading books is much better than watching TV! How many of you watch TV? No doubt all of you do each and every day. It is so easy to just sit down on a couch and press 1 little button and waste hours on watching TV shows and movies! Books are better for our Health our Electricity and Education. Good Morning / Good Afternoon Mrs Millward and 7AC today I am going to tell you about why books are better and I mean way better then TV. TV can affect our Health in a way which is sitting down too much on the couch and not doing physical activities outside.A great deal is known about children and television, because there have been thousands of studies on the subject. Researchers have studied how TV affects kids' sleep, weight, grades, behaviour, and more. When using a book reading is exercising your brain and learning words you didn’t know about but when TV comes in all you do is watch and that can easily affect your ey es and then it can affect you behaviour and your grades. When watching TV for hours and when your parents get a bill for the electricity half of the bill is caused by watching TV of course because that is the main problem.In my house we only turn on the TV if we are watching the cricket of watching the News or watching our sport team play and that is all my family use it for. But this isn’t always caused by kids it is caused from parents that work at least once a week and that happens when they have got nothing to do. Say if you are doing an assignment for school and you have been working for hours without getting anywhere. Majority of you would watch TV for a while, while watching you will still be worrying about the assignment and by the time you get back to it you will be stressed.And on top of that books are an excellent way to learn new vocabulary without you even knowing, that’s right, while reading books you involuntary learn new words and the spellings. Imagine you have got this huge test the next morning and then you’re watching TV and then you’re studding on the way to school and then you get a FAIL!!! On your test. How bad would that be? If it was me I would feel really embarrassed. So you have just heard some things that can affect your health and your parents bills and your own education that your parents are paying for but lso when our parents where alive they only got a TV when they were around 16 or 17 of age. And look us and then think of your parents back in the past. And they didn’t have computer games either. So 7AC and Mrs Millward I think I convinced you that books are much better then Television. And so when you get I want you not to go to the living room and turn on the TV I want you to Study on your Math exam and do your HOMEWORK!!! Don’t Touch the TV Do Your Homework Don’t Touch the TV Do Your Homework

The Origins of British Columbia in Canada

The Origins of British Columbia in Canada The province of British Columbia, also known as BC, is one of the 10 provinces and three territories that make up Canada. The name, British Columbia, refers to the Columbia River, which flows from the Canadian Rockies into the American state of Washingon. Queen Victoria proclaimed British Columbia a British colony in 1858. British Columbia is on the west coast of Canada, sharing both a northern and southern border with the United States. To the south are Washington State, Idaho, and Montana, and Alaska is on its northern border. Origin of the Province Name British Columbia refers to the Columbia District, the British name for the territory drained by the Columbia River, in southeastern British Columbia, which was the namesake of the Columbia Department of the Hudsons Bay Company. Queen Victoria chose the name British Columbia to distinguish what was the British sector of the Columbia District from that of the United States or the American Columbia, which became the Oregon Territory on August 8, 1848, as a result of a treaty. The first British settlement in the area was Fort Victoria, established in 1843, which gave rise to the city of Victoria. The capital of British Columbia remains Victoria. Victoria is the 15th largest metropolitan area of Canada. The largest city in British Columbia is Vancouver, which the third-largest metropolitan area in Canada and the largest in Western Canada. The Columbia River The Columbia River was so named by American sea captain Robert Gray for his ship the Columbia Rediviva, a privately owned ship, which he navigated through the river in May 1792 while trading fur pelts. He was the first non-indigenous person to navigate the river, and his voyage was eventually used as a basis for the United States claim on the Pacific Northwest. The Columbia River is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The Chinook tribe who live near the lower Columbia River, call  the river Wimahl. The Sahaptin people who live near the middle of the river, near Washingon, called it Nch’i-Wna. And, the river is known as swahnetkqhu by the Sinixt people, who live in the rivers upper reaches in Canada. All three terms essentially mean the big river.

Describe labor market trends and globalization as they relate to the Essay - 1

Describe labor market trends and globalization as they relate to the job market. Explain the importance of networking in reaching your career goals - Essay Example There are several pros and cons of informational interviewing. A major advantage of conducting an informational interview is one gets first hand information about working in a particular job or industry (UC Berkeley Career Center, n.d.). It will give an idea of the career paths available for individuals in a particular field. Furthermore, one can get tips from professionals on how to prepare for a certain career. An informational interview enhances one’s communication skills and warms up one for a real job interview. It will be the beginning of establishing professional relationships with people who are in the same industry as one’s career (UC Berkeley Career Center, n.d.). Building of networks like these may later on create job leads in the future. Informational interviewing also has its drawbacks. One must be careful about choosing the professional to interview. If the interviewee is a person who is not happy with his job, then the views that he might share may be biased and will affect the interviewer negatively. Another disadvantage is that some interviewees might misconstrue the informational interview as a request for a job.
