The Trumpet - A Delight for the Primal Senses essays

The Trumpet - A Delight for the Primal Senses essays The trumpet invokes the primal sense stimuli of sound, sight, and touch through its evocative use of melody, tone, and rhythm. The trumpet, of all the brass instruments, is the one that sounds the most like a human voice. It usually provides the melody of a jazz work because of the clear, bell-like sound of its notes. Its tone is one of clarity that can cut through the noise of a crowd or audience at an orchestra. Its noise rises above the dull thump of the lower-toned base instruments like the tuba, the drone of the woodwinds, and the buzz of the string instruments. Even an untrained ear can identify the sound of a trumpet, almost as if its sound was hard-wired into the brain from birth. When there is no singer, the trumpet is the voice of the orchestra. Like children respond to their mothers voices, so we respond to the voice of the trumpet out of this primal memory, this love of speech and articulation. The trumpets quick notes of brightness, unlike the more mellow and difficult tones of different sections of the orchestra need no training to understand because they speak to the heart of the listener. Because of its communicative power, a trumpet has been used when fighting wars and training troops. Once upon a time, no fighting unit was complete without a trumpet. A trumpet can speak to sleeping solders when it acts as a bugle to rally people awake, or to send the soldiers asleep during taps. Even many childrens camps have buglers to rally the young campers awake and to send them to sleep at night. A trumpet can also sound a call of triumph, one reason that angels are often depicted playing trumpets. Trumpets caused the walls of Jericho to come tumbling down with their clear tenor voices, enabling justice to triumph, and announced the birth of prophets. In many Christmas carols, the sound of the trumpet is one of the featured instruments, like Hark the Herald Angels Sing. ...

A Guide to Internet Privacy Laws and Ethics Essay Example for Free

A Guide to Internet Privacy Laws and Ethics Essay With information systems, privacy deals with the collection and use or misuse of data More and more information on all of us is being collected, stored, used, and shared among organizations Who owns this information and knowledge? Privacy is a status wherein an individual can work on his/her information in seclusion, resulting in a selective revelation of ones identity and information. Privacy can mean anonymity in case a person wants to remain unidentified. Privacy can also be related to the security aspect of an individual or information. The definitions of privacy can differ across individuals and cultures. The invasion of privacy can be avoided by the issue of privacy laws. Internet Privacy and Ethics Using the Internet often comprises the use of social networking sites, email facilities and the browse of various other websites. Internet privacy comes on the scene when it comes to website users giving out their personal details on the Internet. For certain websites, which facilitate online shopping, the users are made to input their credit card numbers. In case of emailing sites, there are issues about whether third parties should be allowed to store or read emails without informed consent. Whether or not, the third parties should be permitted to track the visitors on a website, is another major privacy concern. The other important Internet privacy issue is whether the sites that gather personally identifiable information from the users should store or share it. Internet privacy can be considered as a subset of computer privacy. Computer privacy consists of the data privacy relating to the avoidance of the improper disclosure of the personally identifiable information collected and stored by websites. The effective sharing of data while protecting the private information is the real challenge. Privacy and the Internet * Huge potential for privacy invasion on the Internet * E-mail messages * Visiting a Web site * Buying products over the Internet * Platform for Privacy Preferences (P3P): screening technology * Children’s Online Privacy Protection Act (COPPA), 1998: requires privacy policies and parental consent * Potential dangers on social networking Web sites E-Mail Privacy * Federal law permits employers to monitor e-mail sent and received by employees * E-mail messages that have been erased from hard disks can be retrieved and used in lawsuits * Use of e-mail among public officials might violate â€Å"open meeting† laws Computer Matching is a mass surveillance technique involving the comparison of data about many people, which has been acquired from multiple sources. Its use offers potential benefits, particularly financial savings. It is also error-prone, and its power results in threats to established patterns and values. The imperatives of efficiency and equity demand that computer matching be used, and the information privacy interest demands that it be used only where justified, and be subjected to effective controls Computer matching is the comparison of machine-readable records containing personal data relating to many people, in order to detect cases of interest. The technique is called computer matching in the United States, and data matching in Australia and Canada. Although the latter term is perhaps more usefully descriptive, the United States term is more common in the literature, and is used in this paper. The Computer Matching and Privacy Protection Act The Computer Matching and Privacy Protection Act of 1988 (5 U.S.C. 552a(o) et seq.) amended the Privacy Act by describing the manner in which computer matching involving Federal agencies could be performed and by adding certain protections for individuals applying for and receiving Federal benefits. As amended by the Computer Matching and Privacy Protection Act, the Privacy Act requires Federal agencies involved in computer matching programs to: Negotiate written agreements with the other agency or agencies participating in the matching programs; Obtain the relevant Data Integrity Boards approval of the match agreements; Furnish detailed reports about matching programs to Congress and OMB; Notify applicants and beneficiaries that their records are subject to matching; and Verify match findings before reducing, suspending, terminating, or denying an individuals benefits or payments. Though the Computer Matching and Privacy Protection Act certainly involves detailed procedures, including obscure Data Integrity Boards, it is probably most notable for the fact that it institutionalizes sharing of data among federal government agencies. Information collected for one purpose may be used for different purposes by a different federal agency. Though integrity and fairness seem assured by the Act, privacy is not. Flaming also known as bashing, is hostile and insulting interaction between Internet users, often involving the use of profanity. Flaming usually occurs in the social context of an Internet forum, Internet Relay Chat (IRC), Usenet, by e-mail, game servers such as Xbox Live or PlayStation Network, and on video-sharing websites. It is frequently the result of the discussion of heated real-world issues such as politics, religion, and philosophy, or of issues that polarise subpopulations, but can also be provoked by seemingly trivial differences Spam is most often considered to be electronic junk mail or junk newsgroup postings. Some people define spam even more generally as any unsolicited email. However, if a long-lost brother finds your email address and sends you a message, this could hardly be called spam, even though it is unsolicited. Real spam is generally email advertising for some product sent to a mailing list or newsgroup.

A Critical Analysis of the Poetry of Marvell Essay -- Biography Biogra

Critical Analysis of The Garden    As with many of his poems, Andrew Marvell wrote The Garden to put forward his point of view and then argue it logically. In The Definition of Love, for example, he writes about unrequited passions, insisting that Fate itself acts against true love; in The Garden he takes a similarly pessimistic viewpoint and takes it to its misanthropic limits, attempting to argue that being at one with nature and away from other people is the best way to live.    All poets have traits and habits that define their own style - some more so than others. Marvell's style is particularly recognizable, as he commonly uses several easily identifiable techniques and images. Of the latter, The Garden features many of Marvell's staple ingredients. Central to the entire poem is the idea of pure nature, of a world without the intrusion of mankind: Marvell's own Eden. In his poetry, he takes every opportunity to extol the virtues of a type of hermitage, of being at peace with oneself and the universe as a whole; this can also be seen as central themes in poems...

Macbeth Act 2, scenes 1 and 2 Essay

In Act 2 Banquo is found with his son Fleance, in the courtyard of Macbeth’s castle at â€Å"witching hour†. The night is cold and dark, with fog surrounding the castles boundaries. Banquo is becoming nervous and this is evident from what he says to his son, Fleance, â€Å"Hold, take my sword. – There’s husbandry in heaven, Their candles are all out. – Take thee that too.† Even though it is obvious he would like to rest, he is fearful of nightmares whilst he sleeps, the following quote suggests this, â€Å"A heavy summons lies like lead upon me, And yet I would not sleep; merciful powers, Restrain in me the cursed thoughts that nature Gives way to in response.† As Banquo was patrolling the area he hears a noise, â€Å"Who’s there?† startled and scared at this he says to Fleance, â€Å"Give me my sword.† Banquo is tired and is trying to maintain full alert, showing he is on edge; listening out for any anything and everything that might occur. As Macbeth steps out of the dark, slightly visible by Banquo, Macbeth replies: â€Å"A friend† Banquo feels relieved as he can now put his mind at rest, because he has seen a friendly face at such time of night and hostile surroundings. After Macbeth had been socialising with Banquo, Banquo remembers to ask Macbeth a question that had been troubling him about the witches, â€Å"I dreamed last night of the three weird sisters; To you they showed some truth.† Macbeth tries quickly to change the subject by answering, â€Å"I think not of them;† this is because he does not want to be linked to the murder of Duncan that Macbeth is plotting. Macbeth then tries to bribe Banquo, we see this from â€Å"If you shall cleave to my consent, when ’tis, it shall make honour for you.† By this Macbeth is trying to imply that if Banquo stands by him and stays loyal to him, when he Macbeth needs him, Banquo will not regret it and will be honoured by others. Banquo replies, â€Å"So I lose none In seeking to augment it, but still keep My bosom franchised and allegiance clear, I shall be counselled.† Which basically translates, as long as Banquo does not have to risk his honour in providing his life and can keep a clear conscience, then he will be advised by Macbeth. This indicates that Banquo might be picking up on Macbeth’s intentions on becoming king of Scotland. So far we can see the differences in the two characters personalities. Banquo is a loyal person, kind, open to discussions, friendly and honourable to the king â€Å"Duncan† as well as to his friends and family. On the other hand Macbeth is the complete opposite in every way, he appears to be dishonourable (as we know he is planning Duncan’s murder), a liar, untrustworthy and an actor of personalities. When Macbeth is on his own his mind becomes delusional goes into a frenzy he starts to think about the side affects of his actions, but is hyped up and ready to do the deed of killing Duncan. It is clear from, â€Å"Is this a dagger that I see before me, The handle towards my hand? Come, let me clutch thee: I have thee not, and yet I see thee still,† that Macbeth is hallucinating. However, during the build up to the murder Macbeth continues to be drawn by the image of the dagger to Duncan’s room. â€Å"I see thee still and on thy blade and dudgeon gouts of blood, which was not so before.† From this we are informed that Macbeth has now imagined Duncan’s blood on the dagger, but this does not put Macbeth off as we see from when the bell is rung, which was a sign from Lady Macbeth that the coast was clear. Macbeth does not hesitate as he confidently says, â€Å"I go, and it is done. The bell invites me. Hear it not, Duncan, for it is a knell that summons thee to heaven or to hell. Yet earlier, in Act 1 scene 7 we see that Macbeth had doubts about murdering Duncan as he thinks, â€Å"If it were done when ’tis done, then ’twere well it were done quickly. If th’assassination could trammel up the consequence and catch with his surcease, success, that but his blow might be the be-all and the end all – here†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬  This is where we realise he is feeling uneasy about killing his friend and worrying about the possible consequences. The reason Macbeth changed his mind about murdering Duncan is because Macbeth really wanted to be King more than anything, and once the witches prophesised that this would happen, it made Macbeth more convinced that he should carry out the murder. The changes of his mind show us that Macbeth is easily misled. I feel Macbeth would not have been brave or foolish enough to kill Duncan had his wife not persuaded him to do it as we see from her planning and convincing Macbeth that their murder won’t fail, â€Å"We fail? But screw your courage to the sticking place, and we’ll not fail. When Duncan is asleep, whereto the rather shall his day’s hard journey soundly invite him. Although we have seen Macbeth’s guilt about wanting to kill his friend and someone who he really respects, he is driven to follow through his ambition of becoming king because of his wife, Lady Macbeth. Once Macbeth has killed Duncan he feels guilty which causes him to become hysterical. Although his wife tries to calm him down it is evident that she fails because she instructs him to, â€Å"Go get some water and wash this filthy witness from your hands.† After washing his hands Macbeth still thinks the blood is still on him, due to the burden he is carrying from the dirty deed he carried out. He is so ridden with guilt he cannot even bring himself to say â€Å"Amen† because it is such a religious word, and he knows that now he has committed such a crime, he cannot be a holy person. Macbeth is so tortured in his mind that he imagines he hears a voice cry â€Å"sleep no more†. He feels he will be punished for killing a defenceless man and in return he will be deprived of sleep. He refuses to go back into Duncan’s chamber because the sin he has performed is so great he cannot face up to it again, we learn this from, â€Å"I’ll go no more. I am afraid to think what I have done, look on’t again, I dare not.† The following quotes also confirm his guilt, â€Å"To know my deed, ’twere best not know myself.† Which seems to suggest that he would like to disown himself, and â€Å"Wake Duncan with thy knocking: I would thou couldst† implies that Macbeth wishes that Duncan would wake up at the sound of the noises Macbeth hears. Lady Macbeth is not able to fight off Macbeth’s mood swings and conscience. She is trying to be positive and tries to have an optimistic answer for all his negative comments. We see this many times, one example is after Macbeth has killed Duncan he says, â€Å"This is a sorry sight†, but his wife replies â€Å"A foolish thought, to say a sorry sight.† Act 2 ends with Macbeth continuing to feel guilty and on edge with every noise he hears.
