A Quick Tutorial on the Perl Array Pop() Function

A Quick Tutorial on the Perl Array Pop() Function When writing a Perl script you might find it handy to use the pop() function, which looks like this: $ITEM pop(ARRAY); Perls pop() function is used to remove and return (or pop) the last element from an array, which reduces the number of elements by one. The last element in the array is the one with the highest index. Its easy to confuse this function with shift(), which removes the first element from an array. An Example of Using the Perl Pop() Function myNames (Larry, Curly, Moe);$oneName pop(myNames); If you think of an array as a row of numbered boxes, going from left to right, it would be the element on the far right. The pop() function would cut the element off the right side of the array, return it, and reduce the elements by one. In the examples, the value of $oneName becomes Moe, the last element, and myNames is shortened to (Larry, Curly). The array can also be thought of as a stack- picture of a stack of numbered boxes, starting with 0 on the top, and increasing as it goes down. The pop() function would pop the element off the bottom of the stack, return it, and reduce the elements by one. myNames (Larry,Curly,Moe);$oneName pop(myNames);

Career Progress Initiating, Inspiring, Leading Essay

Career Progress Initiating, Inspiring, Leading - Essay Example When I worked as an engineer at Intel from 2001 to 2004, I inspired my mediocre team into a top unit, by initiating an out-of-the-box thinking environment that resulted in over 30 technical innovations in just 1 year. I followed up this innovation culture by leading a cross-departmental platform where engineers from across the company could contribute and share a think tank of ideas that solved several long-running problems of many a unit. I learnt that inspiring others to achieve their dreams is a wonderful achievement in itself. I also learnt that taking initiative to lead a change process is well worth the risk of failure. The team of engineers that I led published ten articles on the prestigious Intel Disclosure Forum in one year - a record by far. From 2004 to 2007, I worked as a business consultant at Accenture, in charge of setting up the billion-dollar industry giant's operations in China. It was a daunting task to apply the best practices of the company in the traditional Chinese environment. I found my way around the problem in two ways. Customizing these practices to best suit the local needs, and innovating new ideas that helped the client learn and adopt them. I learned to interact with the top management and the employees of several Chinese companies to make them familiar of the changing business realities and inspiring them to embrace new ideas. This consulting experience gave me tremendous insight into different businesses, managerial philosophies, operational styles and global perspectives. I also got to learn how to communicate with top executives and persuade them to see my point of view. My Candidacy Since I worked as tennis coach I have always dreamed of building a tennis school of my own. Since I applied last time at Wharton my life has been very eventful. I have gone ahead and implemented my dream to some extent. I have been making plans and accumulating a small fortune on my own for my school all this time and things finally fell into place early this year. A high school was on sale in the neighborhood and I decided to buy this school and transform it into to a sports school. This sudden turn of events has caught me unawares on several skills of entrepreneurship that I had no idea about. First, I learnt how to write a business plan and persuade others to invest in it. I raised money from eleven colleagues in Intel and Accenture and four alumni. They became my founding shareholders. Secondly, I learnt the psychological side of managing people. It took a lot of efforts to make the former management team of the school to understand my ideas and to keep them from quitting. Third, I learnt about marketing & sales, a function that I had never touched before. This entrepreneurship experience has given me tremendous confidence in myself and hands-on experience in setting-up and running a business from the scratch. I feel, I am better equipped to understand the latest theories and practices of the business world than last year. I am also more focused in my approach to studies, with a well etched out career plan. Career Goals Based on the current business, I set my short-term career goal to build a brand name for this sports education venture by associating it with famous athletes, pioneering education philosophies, and sponsoring local sports events. I want to

Student Assessment Assignment Example | Topics and Well Written Essays - 1250 words

Student Assessment - Assignment Example They also fail to measure the need for student growth which is needed to plan future instruction or lecture strategies (Tsagari). This has called for re-examining the traditional or conventional approach to testing qualities, hence a movement of alternative testing (Rachmnn 2005). Wiggins (1998) and Darling-Hammond, Ancess and Falk (1995) also pointed out the problem of deep understanding with conventional testing, emphasizing that deep understanding is robust learning which can be applied to different situations. The criticism pointed out by Wiggins and Darling-Hammond is that conventional forms of testing such as exercises, quizzes and multiple choice questions are not capable of gauging this understanding among students (Williams 2007). Due to these criticisms Wiggins and Darling-Hammond, Ancess and Falk are in favor of performance assessment, in which instead of testing a student using multiple choice questions, they are to work on projects, conduct interviews, and presentations in order to demonstrate their understanding to the reviewers/teachers (Ross 2006) . The basic premise of the vision of authentic achievement as proposed by Newmann, Secada, and Wehlage (1995) outlines the creation of more interesting yet challenging assessment tools for students. Teachers can encourage students to produce more intellectual work in the form of real world applications, and hence increase their performance. Although the basic assumption behind traditional and authentic assessment is common, which is to develop prolific citizens, the former approach tests the students on the possession of certain knowledge while the latter tests the students on the application of knowledge (Mueller 2008). Another difference between the two approaches is that in the traditional approach knowledge is the curriculum determined prior to delivery while in the latter the task to be executed by the students is determined first, which would include the application of knowledge and the curriculum to enable the students to perform the task is determined later (Mueller 2008). Dictionary definition of rubric is "an authoritative rule, especially, a rule for conduct of a liturgical service" (Dictionary 2008). Rubrics basically are assessment tools with the help of which the teacher can predefine what basis the paper or work will be judged on and how scoring will be done on the basis of the predefined criteria (ALTEC 2008). Hence, I agree with the statement that "using rubrics to code student work makes the expectations for success clear, and thereby solves a major problem of traditional assessment, namely, the mystery of marking/evaluating student performance" (Course Resource). If a student does not get a good grade despite knowing the rubrics, the teacher is to a point faultless because the student was informed about the assessment criteria and both students and teacher share with each other the requirements for a particular project (Holbrook 2001). Assessments by rubrics are very detailed and give students a much more clear idea of what they are expected (Walvoord n.d.).It is also very helpful as an assessment tool as it is an ongoing review process where students can also self assess themselves on the basis of preset criteria before submitting their work (Andrade 2001).

Jekyll and Hyde for Teacher Essay Example for Free

Jekyll and Hyde for Teacher Essay To begin with, both alter personas are of brutal and ferocious nature as they manifest disturbing evil intentions. Tyler Durden vandalizes property, craves annihilation, obliterates his own apartment, has full knowledge about all varieties of homemade explosives, and is brave enough to cause all kinds of chaos. Most prominently, Tyler, a follower of nihilism, founds â€Å"fight club†, a place for men to fight each other, feel alive, and ignite their inner rage. He expresses his nihilistic point of view in the following line: â€Å"It\s easy to cry when you realize that everyone you love will reject you or die. On a long enough timeline, the survival rate for everyone will drop to zero.† Hyde, a detestable man in appearance, tramples a young girl on the street and is responsible for the terrifying murder of Danvers Carew. Hyde was described by a maid to be â€Å"stamping with his foot, brandishing the cane, and carrying on like a madman† at the murder scene. Even more terrifying is the satisfaction he feels for his violent actions, that Jekyll later confesses to. Furthermore, the various characters that encounter Hyde are said to feel a deep personal hatred for him. Many dark adjectives, such as â€Å"evil† and â€Å"detestable†, are repeatedly used to describe him. As the story progresses, both Jekyll and The Narrator realize that what their alter egos aim to achieve is not what they desire. This belated sense of realization comes when Hyde commits a murder and Jekyll progressively comes to the conclusion that he is beginning to transform into Hyde, involuntarily, without the potion. However, The Narrator’s realization comes at the end of the novel when he discovers that Tyler is his own alter ego, that takes over in his sleep. Additionally, he realizes that fight club members are accountable for all the buildings that are being wrecked and all the people that are being killed with Tyler’s orders. The narrator tries cleaning up after Tyler, however, Jekyll does not try to right Hyde’s mistakes. The Narrator tries defusing a bomb and preventing the chaos caused by Tyler’s orders by convincing the fight club members to stop. However, his plan ultimately fails as the members are previously ordered by Tyler to not answer any questions or let anyone stop them. At this point, both characters lose control over their mind and body and have to liberate themselves from their demonic alters. In order to achieve that, The Narrator asks Marla to help him stay awake, which is not a permanent solution. Jekyll forages for a specific type of chemical, that he requires to make his potion and get rid of Hyde. However, he fails to obtain this ingredient. By the end, both Jekyll and The Narrator opt to commit suicide to end their life and by extension the lives of Hyde and Tyler. The Narrator states that â€Å"To god, this looks like one man alone, holding a gun in his own mouth†¦I’m not killing myself, I yell. I’m killing Tyler.† This destructive violence could be ideally explained through the lens of psychoanalytic approach.

Conrad’s Congo Journey :: Biography Biographies Essays

Conrad’s Congo Journey Joseph Conrad’s own experiences during his trip through the Congo helped him provide a foundation for the writing of Heart of Darkness. In 1890, Conrad took a job as a captain on the river steamer Kinshasa. Before Conrad took this job, he had worked for the French merchant navy as a way to escape Russian military service and also to escape the emotional troubles that had plagued him. Conrad had been in a financial crisis that was resolved with help from his uncle. After this series of events, Conrad joined the British merchant navy at the beckoning of his uncle and took the job as the captain of a steamboat in the Congo River. An important fact to remember is that Conrad was a young and inexperienced man when he was exposed to the harsh and dangerous life of a sailor. His experiences in the West Indies and especially in the Belgium Congo were eye opening and facilitated his strong outlooks that are reflected in the book Heart of Darkness. Conrad’s journey th rough the Belgian Congo gave him the experiences and knowledge to write about a place that most Europeans would never see in their lives. The diaries Conrad kept during his journey through the Congo gives detailed descriptions of the monotonous African landscape. Conrad wrote that the landscape of the African coast looked the same every single day.[1] This is reflected in Marlow’s narration of the jungle where shapes and forms cannot be made out clearly. The monotonous landscape differed from what Conrad had expected of this exotic location. When he was still a young kid, he had once boasted that he would someday journey to the heart of Africa. However, the actual journey was not at all what he expected it to be. Conrad was shocked at the men in the African colony. He was repulsed by the European colonizers because of the horrible treatment of the natives as well as the unlawful aggressive pursuit of loot. Conrad witnessed atrocities committed by the European colonizers, which helped to form his opinions on the colonization of Africa. In the novel, Conrad uses sarcasm to display his displeasure towar ds the European colonizers’ treatment of the natives. The Europeans in the book are called pilgrims and the natives are called cannibals, however the pilgrims are the ones who are much more willing to use force to resolve their problems.

Nature of Evil in Othello

The Nature Of Evil In Othello The Nature of Evil in Othello William Shakespeare’s Othello uses different and unique techniques in his language to express the nature of evil throughout the play. Verbal twists and the characters most importantly stress the act of evil. Iago, most of all is portrayed as the â€Å"villain† or â€Å"protagonist in the play. Shakespeare uses this character to set the basis of evil. Each plot point is spiraled further into tragedy due to the nature of Iago and his manipulative language towards the other main characters. Corruption overcomes the Venetian society as Iago uses his crafty skills of deceit. The plan to have Othello turn against the ones he loves is the perfect example of evil’s nature. The power struggle is evident between these two. This situation is the start to Iago’s plan to corrupt the society and take Othello’s place. The root of Iago’s â€Å"evil† is jealousy indeed, in turn changing into a power hungry manipulator. Iago is tired of acting like one â€Å"courteous and knee-crooking knave† like he always appears to be [I. i. 46]. Since Iago is reluctant to choose to be a master, he is the servant that bites off the fame and â€Å"keep yet their hearts attending on themselves,† still showing his service to his master but instead is more self-preserving with no attachments at all towards the master [I. i. 52]. Irony is used diligently in Shakespeare’s unique language style. Referred by Othello as â€Å"honest Iago†, the irony is very evident in this title. Iago is everything but honest but this proves how easily led and manipulated Othello is. The traits Iago possess are unexpected to a normal villain. He comes across as charming and smart, he can also be referred to a wolf in sheep’s clothing. For example, he knows Roderigo is in love with Desdemona and figures that he would do anything to have her as his own. Iago says about Roderigo, â€Å"Thus do I ever make my fool my purse. † [I iii. 355,] By playing on his hopes, Iago is able to conjure money and jewels from Roderigo, making himself a profit, while using Roderigo to further his other plans. He also thinks stealthy on his feet and is able to improvise whenever something unexpected occurs. When Cassio takes hold of Desdemona's hand before the arrival of the Moor Othello, Iago says, â€Å"With as little a web as this will I ensnare as great a fly as Cassio. † [II, i, 163] This language demonstrates the evil inside Iago’s goals of retrieving absolute power. He actually even says of himself, â€Å"I am an honest man†¦. † [II, iii, 245]    Iago slowly corrupts the character’s thoughts, creating ideas in their minds without implicating himself. His â€Å"medicine works! Thus credulous fools are caught†¦. † [II, i, 44] â€Å"And what's he then that says I play the villain, when this advice is free I give, and honest,† [II, iii, 299] says Iago. In turn, people rarely stop to consider the fact that old Iago could be deceiving and manipulating them; yet they are convinced that he is â€Å"Honest Iago. † From these quotes from â€Å"Othello† it is proven that the dialogue used between Iago and the others is manipulative causing an evil outcome. Iago’s complexity in character grows as the play comes closer to a conclusion. The tricky and crafty way Shakespeare uses the evil in Iago is to make him seem amoral as opposed to the typical immoral villain. At the climactic end of the play, Iago's plot and plan is given away to Othello by his own wife, Emilia. Iago kills his wife seeing her as a non entity to his vicious foresight. He kills her not out of anger but for more pragmatic reasons. She served no purpose to him anymore and she can now only hurt his chances of keeping the position he has been given by Othello. Iago's black hearted taking of Emilia's and Roderigo's lives is another proof of his amorality. The root of all evil stems from some would say money, but in this case it is power. To drive Iago to get the power he wants, he is fueled by jealousy. The way jealousy affects the other characters is uncanny. Othello is led down the same path as Iago which is exactly what he wants. The other characters all play off Iago’s misfortunes in turn making Iago’s manipulative plan a success. â€Å"Divinity of hell! When devils will their blackest sins put on, they do suggest at first with heavenly shows, as I do now. †(II, iii, 348) This is the first quote that it is evident Iago is jealous. He is the voice of jealousy in its entirety, giving way to the evil deeds that drive the play. There is a counter argument to the fact whether Iago is truly â€Å"evil.    In Richard Grant’s, Studies in Shakespeare, describes the dual aspects of the character of Iago, whose external demeanor is characterized by warm sympathy for his friends and apparent trustworthiness among his peers, but whose real and inner nature is amoral, heartless, and entirely self-interested. The fact that Iago was the youngest out of the group of characters, Grants theory on Iago’s evil nature i s that he adapted it by consciously adopting it. â€Å"Brave, and a good soldier, he was also of that order of ability which lifts a man speedily above his fellows. His manners and his guise were of a dashing military sort; and his manner had a corresponding bluntness, tempered, at times, by tact to a warm-hearted effusiveness, by the very tact which prompted the bluntness. † [Grant: Studies in Shakespeare, Houghton, Mifflin and Company, 1886, pp. 258-79] Grants theory can twist the minds of what Iago has always been thought of to be. The typical villain is taken as something else in this scenario. Being in the military, in is in Iago’s nature to make his way to the top. His actions may not have been particularly â€Å"evil†, but yet understood. Another excerpt from Grants theory, â€Å" All the principal personages of the tragedy, Desdemona and Cassio included, thus regard him; although Cassio, himself a soldier, is most impressed by Iago's personal bravery and military ability. In speaking of him, he not being present, the lieutenant calls him the bold Iago, and in his presence says to Desdemona that she may relish him more in the soldier than in the scholar,† [II. i. 75, 165-66] [Grant: Studies in Shakespeare, Houghton, Mifflin and Company, 1886, pp. 234] further explains how the soldier instinct in Iago has replaced his demeanor rather than â€Å"evil. The sheer importance of the character Iago is immense. The theory of Iago being â€Å"evil† or just jealous of a military position is up for debate. The interesting fact about Shakespeare’s characters is the relation they have in real life. As Grant explains, â€Å"In Iago Shakespeare has presented a character that could not have escaped his observat ion; for it is of not uncommon occurrence except in one of its elements, utter unscrupulousness. But for this, Iago would be a representative type, representative of the gifted, scheming, plausible, and pushing man, who gets on by the social art known as making friends. This man is often met with in society. Sometimes he is an adventurer, like Iago, but most commonly he is not; and that he should be so is not necessary to the perfection of his character,† [Grant: Studies in Shakespeare, Houghton, Mifflin and Company, 1886, pp. 205] you can see the relations Iago has to a specific stereotype of a person in the real world. In another excerpt, â€Å"Thus far Iago's character is one not rare in any society nor at any time. Yet it has been misapprehended; and the cause of its misapprehension is the one element in which it is peculiar. Iago is troubled with no scruples, absolutely none. He has intellectual perceptions of right and wrong, but he is utterly without the moral sense. He has but one guide of conduct, self-interest. [Grant: Studies in Shakespeare, Houghton, Mifflin and Company, 1886, pp. 205] Grant explains how Iago is just lacking moral sense. He may not in fact be â€Å"evil† at all. He can simply just be greedy and envious in result of not gaining the position in the military. â€Å"Iago, however, had no thought of driving Othello to suicide. Far from it. Had he supposed the train he laid would have exploded in that catastrophe; he would at least have sought his end by other means. For Othello was necessary to him. He wanted the lieutenancy; and he was willing to ruin a regiment of Cassios, and to cause all the senators' daughters in Venice to be smothered, if that were necessary to his end. But otherwise he would not have stepped out of his path to do them the slightest injury; nay, rather would have done them some little service, said some pretty thing, shown some attaching sympathy, that would have been an item in the sum of his popularity. There is no mistaking Shakespeare's intention in the delineation of this character. He meant him for a most attractive, popular, good-natured, charming, selfish, cold-blooded and utterly unscrupulous scoundrel. † (pp. 333-34) [Grant: Studies in Shakespeare, Houghton, Mifflin and Company, 1886, pp. 205] This excerpt further explains Iago’s nature being exactly how Shakespeare intended yet a little different than what the average reader would think of him. The nature of evil is strictly evident as the play comes to an end, yet it is viewed as an opinion or a theory whether Iago is truly â€Å"evil. † Ironically, Iago’s words speak louder than his actions, proving how legitimate Shakespeare’s use of language for the character was. This dynamic use of language is significant because it can alter the thought of the reader whether Iago was truly evil or just using military tactics to better him. Iago and his use of language set the main plot for every characters outcome.

Every now and then you run into somebody that will tell you, Im not afraid of anything, but that is almost impossible. We all come into this world fearing something, whether it would be the fear of snakes, spiders, or even swimming in the ocean. My fear would happen to be failure. Failure has always been my biggest fear. Ive always wanted to make my parents and friends happy with everything I do. I constantly feel as if I have two giant rocks sitting on my shoulders because I tell myself that I have to succeed in every challenge that comes my way. Both of my siblings havent done that great in life which upsets my parents, so I want to prove to them that they have raised me right. I am going to show them that I can graduate college and obtain a job. A lot of the people I know think that I am going to end up just like my siblings, but my goal is to prove them wrong. But there is also that mental block that If I make one bad choice in life, I am going to blow my chances away. Don’t waste time! Our writers will create an original "My Definition of Failure" essay for you Create order Expectations have always got the best of me when it came to my parents wanting to make my decisions for me. After I finished my senior year of high school, my parents suggested that I should go to college and major in a scientific field to become a doctor. I honestly felt that I would fail in life if I didnt get a job that landed me a hefty paycheck at the end of every month. But the more I thought about it, the more I questioned myself. I realized that when I get older, I am not going to want to wake up every morning dreading work. Thats when I told myself I am going to do whatever makes me happy. I had a long conversation with my parents and told them that I didnt want to be a doctor or a surgeon, but I wanted to pursue a job in the FBI agency field. It is always a pain in the butt when my parents try to make decisions for me. I have realized that they arent doing it to control my life, they just dont want me to fold. Another reason why failure scares me is because it is very embarrassing. Nobody likes to fail, but thats just how it is sometimes. I have always been told that you must first fail to succeed, but I just dont understand why? I hate that when people see you fail in something they automatically think you are not smart or talented enough for that certain task. That has haunted me ever since I was a kid. Every time I dont succeed in something, it feels like I get knocked back on my ass and cant recover. I tell myself that I need to get back up and try again, but why? Why try again if I dont have the strength and courage to succeed? Like I mentioned earlier, if I make one bad mistake, it could haunt me for the rest of my life. How could I look my parents in their eyes and tell them that I failed because I didnt do this, or I didnt do that? Would they be ashamed of me? Would they think that I am not capable of reaching my goals? Past experiences have also scarred me throughout my life when it comes to failure. When I was just a kid my parents had to file for bankruptcy not once, but multiple times. Still to this day they dont think I ever knew about their situation, but I would be up past my bedtime at the bottom of my stairs listening to their late-night conversations. The reason they didnt want me to know was because they didnt want me to worry about the money issue they were having. I assume thats why they want me to go to college and get a degree, so I dont have to struggle like they did. Thats another reason why I have always been scared to fail. I have always been so stressed out over the whole failure thing. I think I have to do this, or I have to do that, to be a happy human being. I just cant tell myself that its okay to do things the way I want to do them, because I feel like if I do that then I will mess my whole life up. My family and friends have always played a huge role in my life by supporting me in anything I do. If it wasnt for them I wouldnt have hurdled some of the obstacles that have rolled my way. I wake up every day worrying if Im making the right decisions in life, and that is why failure has always been my biggest fear.
