Advantages And Disadvantages Ajax And Flex Flash Computer Science Essay

Advantages And Disadvantages Ajax And Flex Flash Computer Science Essay Ajax and Adobes Flash Flex are both used to create dynamic and interactive web applications. Both are platform independent i.e. contents will render the same across different platforms and permits for interface animation. There are many similarities between the two. However, there are considerable differences as well. Say for example, Flash is animation format software that allows for fast download of animation files in a resizable format in order to facilitate files be downloaded over a regular modem connection. Flash creates better interactivity by encoding information in smaller files. Flex technologies developed by Macromedia (now acquired by Adobe) aimed to build Rich Internet Applications (RIAs). On the other hand Ajax is more of a methodology to create RIAs. To create more responsive and interactive web applications, Ajax uses a combination of DHTML, XHTML or XML, CSS, and DOM (Direct Object Model) with XMLHttpRequest and JavaScript. Ajax functions transparently i.e. facilitate behind the scene communication between the server and browser. This report discusses both Ajax and Flash/Flex technology as they battle in making Rich Internet Application(s). Both Ajax and Flex can execute similar functions. However, there are few advantages and disadvantages to both refer to Table-1 for comparisons. 2. What is Ajax? Ajax is a set of technologies which allows a website to be very responsive. Most importantly Ajax supports asynchronous communication and also partial refresh of a web page. Here Partial refresh means; when an interaction event is invoked, for e.g. when a user enters information into a form on a web page and clicks a Submit Button. The server processes the keyed information and returns a partial response specific to the data it receives (See Figure-2). Notably, the server does not transmit back an entire page, compared to the traditional web application which is Click, Wait, and Refresh (See Figure-1), instead, only part of the page is updated. The web application that uses Ajax is events and data driven, where as conventional web applications are driven by pages. Full page refresh Synchronous Time Client click à ¢Ã¢â€š ¬Ã‚ ¦.waità ¢Ã¢â€š ¬Ã‚ ¦..refresh click à ¢Ã¢â€š ¬Ã‚ ¦.waità ¢Ã¢â€š ¬Ã‚ ¦..refresh click Server Data transfer Data transfer Server-side processing Server-side processing Figure-1: Classic Web Application Model Synchronous Communication Partial UI updates Client Time Server Asynchronous Data transfer Data transfer Server-side Processing Server-side Processing Browser UI Ajax Engine User events UI updates Figure-2: Ajax Model Partial UI updates and Asynchronous Communication 2.1. Ajax Asynchronous Asynchronous means after sending data to the server, a client can continue to perform other things whilst the server continues to do its processing in the background. Such as, a user can continue to move the mouse over a map in google website and notice a smooth, uninterrupted change in the display. Compared to the traditional, synchronous, approach here the clients do not have to wait for a response from the server before continuing. Figure 1 and Figure-2 illustrates a Classical vs Ajax web application interaction. An additional significant feature of Ajax-enabled sites is that when an event is triggered, responses from Ajax are not restricted to submitting data in a form or clicking on a link. An Ajax response can be triggered in various number of ways such as moving a mouse over to a particular area on a web page, entering part of an entry in a text field, or dragging a map around with a cursor in Google Map etc. With these cool dynamic interactions among the user and the web page excels web applications nearer to what users experience in rich desktop applications. 2.2. Ajax Technologies at a glance The technologies included in Ajax are as follows: Cascading Style Sheets (CSS) a markup language designed for defining a page presentation style, such as colors and fonts etc. JavaScript a scripting language. XMLHttpRequest is one element of JavaScript technology that is the key to Ajax. It is an object which facilitates to exchange data between the client and the server respectively. Document Object Model (DOM) presents a logical view of a web page in a tree structure. XML the format for transmitting inform from the web server to the client. Nevertheless, other formats such as HTML, plain text or JavaScript Object Notation (JSON) can also be used. Like other web applications, Ajax-enabled web application uses markup languages such as HTML or XHTML to present web pages. Java Server Pages (JSP) as server-side technology can be used to generate web pages. Moreover, server side application systems play an important role in processing Ajax applications. Server side application system such Java2EE, which includes support for user identity management, data validation, and persistence, fits very well with the Ajax methodology Ed Ort (2006). Figure-3: illustrates how all these technologies work collectively to handle a user action. 2.3. Ajax Architecture Browser Client XMLHttpRequest XMLHttpRequest Callback ( ) User Interface Server-side Systems Web and / XML Server Data Stores 1 23 3 4 5 6 HTML + CSS data JavaScript call HTTP Request XML Data JavaScript call HTML CSS Data Data Exchange Figure-3: How Ajax Technologies Handle a User Action A user generates an event on the client (such as entering data to a text field or click a button). This results in a JavaScript function call. an XMLHttpRequest object on the client side is created and configured with a requested parameter and specifies a JavaScript technology callback ( ) function. The XMLHttpRequest object makes an asynchronous HTTP request to the web server. The web server processes the request and returns an XML document that contains the result. The XMLHttpRequest object calls the callback ( ) function, it receives the data and processes the result. The HTML DOM is updated. 2.4. Ajax and Server-Side Java Technologies The technologies that are included in Ajax are either client technologies such as JavaScript technology, or like XML are relevant to the interchange of data between the client and server. The request to the server that the XMLHttpRequest object makes is an HTTP request to the server, handling an Ajax request is similar to handling an HTTP request from a conventional web application. Hence, any server technology can be used to handle the request, including server-side Java technologies such as servlets, JSP and Java Server Faces (JSF) technology. Java Server Faces technology and other Java EE technologies that include support for data validation, user identity management, and persistence, are particularly well-suited for Ajax. For example, a servlet can be used to process a request, manage state for the client, access enterprise resources, and generate the XML for the response. Or a custom Java Server Faces components can be created to handle server-side processing as well as encapsulate the JavaScript technology and CSS for client-side processing. In fact, a library of Ajax-enabled custom Java Server Faces components are already available as part of the Java Blueprints Solutions Catalogue. 3. Flex/Flash 3.1. Background Adobe Flash Professional Multi-Media authoring program developed in 1996 by Macromedia and was acquired by Adobe in 2006. Flash is used to create content for the Adobe engagement Platform. One of the Flashs greatest strength is ease of development. They are very well-liked for creating HTML applications and are hence very significant to web development. Often assist to automate tasks, making web programming and usability faster. For adding animation and interactivity to a web site Flash is one of a well known method. However, it is currently contributions toward developing RIAs (Rich Internet Applications). The release of Adobe Flex technology directly responds to RIA development. Flex is precisely where Flash meets with Ajax. Both technologies aim towards creating RIAs. Flex mechanism is on the presentation level of an RIA. It is a vendor specific product which means it is not free and requires purchase. 4. Comparison between Ajax and Flex Flex is rendered through Flash Player while Ajax is renders through a browser. Flash Player plug-in required for browsers. Plug-ins allows users to supplement web applications with other programs to perform specified functions. However, Ajax does not require the downloading of applications as JavaScript is natively supported by modern browsers. It simply accesses the Web as they are requested. Ajax requires more program writing and coding, provides full CSS and DHTML (dynamic HTML) support. Flex/Flash application platforms are browser and platform independent. In Ajax applications, the browser is the platform. Table-1 illustrates the comparisons on features between Ajax and Flash. Table-1: Comparisons on features between Ajax and Flex/Flash Features Ajax Flex/Flash Audio Supported through external plug-ins (Media Player). Support embedded flash audio. Dynamically load audio. Browser Integration JavaScript natively supported by modern browsers. Flash player plug-in is required. Compatibility Issues Major compatibility differences between browser versions. Minor variations between versions of Flash. CSS Full Support. Limited Support. Programming Model JavaScript. ActionScript. Video Supported through external plug-ins (Media Player). Dynamically load FLV video files or embedded videos. Text Powerful layout capabilities. Text API mimics some HTML functionality. XML Full Support. MXML Not supported natively by JavaScript. Vector Graphics No. Full Support. 4.1. Key Difference The following are key differences on developing Ajax and Flex based online applications: Free and Proprietary One of the biggest features of Ajax is that there are many freely available useful tools online. There is no need for additional IDE in Ajax, as the major components of this technique simply need leveraging. On the other hand Flex is a proprietary tool so developers have to spend a bit to use this development format. A paid tool assures functioning tool to developers. Supports for freely available may not be available. Learning Requirement Flex is already popular to various developers particularly those who have already worked with Flash. Combine this fact with the available platform; developers can expect implementation of Flex based application faster. Ajax, on the other hand, will require more from their developers. Those who wanted to create the application manually, without the assistance of frameworks, will find the task of creating Ajax based applications difficult. This is the reason why Frameworks and libraries are created. Data vs. Looks although each development form can be used for data and its looks, Ajax is more proficient in handling and manipulating data. As an online application, various functions, variables and objects are available and they are simply created to manipulate data. Flex on the other hand, is very useful in creating great looking websites. The reason for this expertise is from that fact that it traces its roots from Flash. 4.2. Advantages and Disadvantages of Ajax and Flex/Flash Advantages Disadvantages Ajax Decrease in bandwidth use. Complex. Requires more coding. Flex/Flash Adobe MXML and Flex allows the integration of internet applications through a variety of desktop functions. Flex has the advantage of Flash player being installed on over 90% of browsers. Support for webcam and microphone. Present information in a visually rich interface. Asynchronous Video and audio integration with the Flex API is very simple and straightforward Flex might not handle lots of records easily. Flex does not read or write files to end-users computer. This is a restriction of Flash Player. More CPU usage. Lack of support for multi-threading. ActionScript is a lot heavier compared to JavaScript. No DOM Model Binary Sockets, cross-domain Access Policy Local Storage JavaScript/ActionScript Integration, E4X Flash Vector graphics APIs Rich components Object model access Data-stores, backend processing, legacy systems Web and/or XML server Browser Client User Interface Ajax Engine JavaScript call HTML + CSS data Server-Side Systems Conclusions This paper has presented an overview of the AJAX technique for developing interactive web applications. Ideas of how to introduce the AJAX approach in teaching web development and examples for lab sessions have been suggested. Incorporating popular technologies into the computing courses appears to motivate the students and in the same time it helps them understand better fundamental theoretical concepts. The AJAX technology requires relatively little new knowledge and can be easily included in teaching web development by focusing on specific parts of existing technologies and demonstrating appropriate applications. The challenge is the constant need of updating the material and selecting relevant examples and tools. However, the experience of learning new technologies and related applications has been rewarding and exciting. The material presented here could be used as an example of embedding emerging technologies in the computing curriculum through existing modules. Although JavaScript has been developed into greater heights, ActionScript is continuously being developed by Adobe. Today, ActionScript could be easily compared to JavaScript as each of these RIA (Rich Internet Application) programming languages has their own advantages and disadvantages. Depending on the need of the developers, they should be able to select which programming language to select.

In this story, there Are four main characters, the cat in the hat, the little boy, the little girl, and the goldfish. The story is definitely written for children. In the story, the children’s parents leave house and the children unattended on a rainy day and they are left with nothing to do. The little boy and girl meet a cat, who loves to have fun. The cat comes into the house against the will of the goldfish. Then the kids and the cat in the hat have lots of fun while making a big mess in the process. The goldfish manages to hurt the cat’s feelings by making a fuss about how the cat made such a mess. And just when all hope seems to be lost and the kids thought there was no way the mess would be clean before their mom was home, the cat in the hat came through. This story had a very positive impact on me. When I was five I had trouble reading. At the time I hated trying to read because I was no good at it.

The Turn of the Screw by Henry James Essays -- The Turn of the Screw H

The Turn of the Screw This novel was, surprisingly, interesting. The intensely complex and intricate (if not confusing!) sentences, upon first thought, made me expect an experience of complete, utter, and total confusion; however, they served not only to keep my interest in the novel – for I had to concentrate to grasp the full, rich meaning of his thoughts – but also to create in me a sense of enjoyment, that of being enriched with the experiences of the main character so that my life and that character's became inseparable, only it occurred not only with the main character, but with the entire plot at once – all characters, all scenes (to which I shall come late), all conversations... everything. I have never seen a man so able to express so much in one sentence, and still be able to have the reader follow his thoughts throughout the entire process. Henry James was a master of expression and grammar. His ability to form a complex, yet coherent sentence did nothing but add to the quality of the novel. The characters alone added to the quality of the novel. It is not so much as they were entirely believable, but they were believable to the extent of their being in a ghost story. The things that happened to these poor characters were not natural in any sense, but they were completely acceptable from within a ghost story.

Theme of Guilt in Hamlet & Fifth Business

There is one human emotion that can paralyse us, lead us to lie both to ourselves and others, to commit actions that we don’t endure, and to cripple any rational thought processes. It is self perpetuating if allowed to get out of control. Its side effects are anger, aggressiveness, fear or reclusiveness. Its symptoms are irrational behaviour, lying, anguish, and lack of self-esteem. It is the strong emotion that can affect our conscience, like an acid drop it corrodes the soul within and in extreme conditions it demolishes one’s life, it is better known as guilt. Guilt is a reoccurring theme in Robertson Davies’ Fifth Business, and William Shakespeare’s Hamlet, that is demonstrated by various characters including, Dunstable Ramsay, Paul Dempster, Hamlet and Claudius and this essay shall compare the theme of guilt between the two literatures. In the novel Fifth Business, guilt is a plague that has spread throughout the lives of Dunstan Ramsay, and Paul Dempster; both characters are drenched with guilt that was a result of a tragic incident caused by Percy Staunton Boyd when he threw the snowball and it â€Å"hit Mrs. Dempster on the back of the head. † (Davies, 2). Dunstan experiences guilt early on in his childhood, realizing it is him who ultimately caused the premature labour of Paul, â€Å"Nevertheless this conversation reheated my strong sense of guilt and responsibility about Paul. † (Davies, 136). As the guilt overtakes his life, Dunny compares what he is feeling to what dying feels like and questions whether that would be better than dealing with this overwhelming guilt: â€Å"Ah, if dying were all there was to it! Hell and torment at once, but at least you know where you stand. It is living with these guilty secrets that exacts the price† (Davies, 19). Born prematurely, Paul Dempster was convicted of being guilty as he was responsible for robbing his mother of her sanity, as explained to him by his father, Amasa Dempster, â€Å"My father always told me it was my birth that robbed her of her sanity. So as a child I had to carry the weight of my mother’s madness as something that was my own doing. † (Davies, 148). Moreover Paul was forced to feel the guilt at a young age, causing him to become frustrated, and that is when he decides to escape from Deptford and runs away with Le grand Cirque forain des St. Vite (Davies, 148), â€Å"‘He was my only teacher till I ran away with a circus. † (Davies, 265). Equivalently in the play Hamlet, the theme of guilt was developed through Hamlet and his most hateful enemy, King Claudius. Hamlet experiences guilt when he recognizes that he has not yet avenged his father’s death and in Act I Scene ii Hamlet reveals that he is upset and disappointed with himself, as he has not taken any actions to attain revenge from Claudius, the murderer of his father. Hamlet then calls himself, â€Å"a peasant slave† and questions, â€Å"What's Hecuba to him, or he to Hecuba, That he should weep for her? What would he do, Had he motive and cue for passion That I have? † (Shakespeare, II, ii, 529. 38-541). Furthermore, Hamlet later decides to relief his overwhelming guilt by commanding the actors to re-enact his father’s death through The Murder of Gonzago, (Shakespeare, III, ii, 284), in order to confirm that the ghost was being truthful and Claudius did kill his father, â€Å"May be the devil, and the devil hath power T' assume a pleasing shape. Yea, and perhaps Out of my weakness and my melancholy, As he is very potent with such spirits, Abuses me to da mn me. I’ll have grounds More relative than this. The play’s the thing Wherein I’ll catch the conscience of the king. † (Shakespeare, II, ii, 561- 567). Eagerly wanting the throne Claudius murdered his brother, King Hamlet by poisoning him when he was sleeping in the garden, â€Å"He poisons him i’ th’ garden for‘s estate. † (Shakespeare, III, ii, 246); his crime was soon revealed by the intelligent Hamlet, when he ordered the actors to create a play outlining the murder of King Hamlet, â€Å"Speak the speech, I pray you, as I pronounced it to you, trippingly on the tongue. †(Shakespeare, III, ii, 190-191). Claudius provoked and disturbed from the play, orders for it to be stopped, â€Å"Give o’er the play. † (Shakespeare, III, ii, 253) and leaves the scene, â€Å"The king rises. (Shakespeare, III, ii, 250) as his dirty crime is now evident. Devoured with the guilt of killing his brother, Claudius confesses and prays to God, hoping that it will cost him less time in Purgatory, â€Å"Oh, my offence is rank. It smells to heaven. It hath the primal eldest curse upon ’t, A brotherà ¢â‚¬â„¢s murder. Pray can I not. Though inclination be as sharp as will, My stronger guilt defeats my strong intent, And, like a man to double business bound, I stand in pause where I shall first begin, And both neglect. † (Shakespeare, III, ii, 37-44). Silent yet deadly, its side effects are anger, aggressiveness or fear and reclusiveness. Its symptoms are irrational behaviour, lying, anguish, and lack of self-esteem. It is the strong emotion that can affect our conscience, like an acid drop it corrodes the soul within and in extreme conditions it demolishes one’s life, it is better known as guilt. The theme of guilt is an important reoccurring phenomenon in Robertson Davies’ Fifth Business, and William Shakespeare’s Hamlet, as demonstrated by a number of characters including, Dunstable Ramsay, Paul Dempster, Hamlet, and Claudius, and this essay compared the theme of guilt between the two literatures.

International Monetary Fund Essay

The question â€Å"To what extent has the International Monetary Fund contributed in revamping the Nigerian economy since the 1980’s?† is a question that helps us to evaluate the true impact of international monetary policy.   In order to further understand the meaning of this question, this paper will examine the following subjects – 1) the meaning of the question, 2) the significance of the question for International Relations scholars, 3) how the question relates to other published work in the area, and 4) what methods would be employed to answer the question. First of all, the question is directly focused on economic impacts.   However, the question is not simply a matter of metrics, because the question is directed at procedural changes as well.   The question is focused on the restructuring of the Nigerian economy.   To only use economic metrics would fail to address the consequences restructuring entails.   When the IMF releases money to a country, they stipulate conditions that the country must meet. Therefore, the question is also directed at the matching the directives of the IMF with the implementation within Nigeria.   The question is not asking if the IMF has had a positive or negative impact on Nigeria, so value judgments can be left aside.   However, there are several hidden economic impacts.   Structural changes to the workforce, changes in occupations, and new roles within the economy are all more difficult to measure, but can be considered a result of economic policy.    Therefore, the question means 1) what are the economic stipulations of the IMF from the 1980’s until now, 2) has the Nigerian government met the requirements of the IMF, 3) what restructuring has occurred within the Nigerian economy as a result of the IMF, 4) what economic measures can be attributed to these changes, and 5) what are the indirect economic impacts of the IMF policies. International relations scholars are interested in this question because the answers yield important data on the impacts of policy.   International relations scholars are often consulted on questions of policy.   It is therefore in their best interest to know the impacts of policies made in the past.   In this regard, they are historians.   First of all, it is critically important for International Relations scholars to understand what the IMF has attempted to revamp within the Nigerian economy by tracing the stipulations as they were made. Additionally, the scholar can look at the Nigerian government’s ability to meet the demands of the IMF.   How well were they able to integrate the changes required by the IMF.   Were there consequences that required new policies in the future?   In tracing these policy changes, the scholar can also piece their own picture together of what the IMF did well (what was effective), and what changes needed to be made in direction in order to achieve effectiveness.   They can also have a unique insight into the culture and politics of Nigeria, as well as the internal culture and politics of the IMF. At this point, the International Relations scholar can also know what economic measures are affected by differing types of policies and requirements.   Additionally, they can make recommendations on what types of correlations can be found between initiative and their impact.   Perhaps some of the most valuable information for International Relations scholars, however, is related to the indirect impact of the IMF’s policies. When looking at the restructuring of the Nigerian economy, the International Relations scholar is able to examine the changes within the population, how people moved around, the changes in families, etc.   This type of information allows for a more comprehensive picture of economic change and the effects policy can have on cultural change.   Also, this may highlight the challenges represented by a more powerful entity interacting with a less powerful entity on a global scale. There has been much written about Nigeria since the 1980’s.   There are environmental reports, malnutrition reports, and economic reports.   However, these all approach Nigeria from a different perspective than the direction of this question.   This question seeks to directly explore the impact of IMF policies and economic aid on the revamping of the Nigerian economy.   As such, this question seeks to provide supporting information of the changes in Nigeria.   It seeks to trace change related to IMF policies alone.    It is impossible to completely know what current conditions in Nigeria are caused solely or even primarily by the IMF policies, however by focusing on the IMF, widespread impacts can be evaluated from IMF policies.   It is taking the infusion of money and change of monetary policy as the starting point and looking for the economic aspects affected.   One of the main sources for research on these types of development programs is found with the World Bank.   A particularly useful document is â€Å"The Evolution of Poverty and Welfare in Nigeria, 1982 – 1992.†[1]Using this document and also information from the IMF, the scholar can tie together the policies of the IMF and the effects. In order to study such a complex issues, a rigorous approach will need to be taken.   It is the most difficult to know the indirect impacts of the IMF’s economic policies.   It is undesirable to claim that changes were a result of IMF policy, if in fact, they owed their existence to a governmental or environmental change.   However, the economy is so closely entwined with all aspects of life, the implications of the IMF policies will be seen to have far-reaching consequences. Therefore, we can begin by examining the Nigerian economy and economic statistics in 1980, and comparing them with the present day to get snapshots of the economic health of Nigeria at these two points in time.   These snapshots, however, encompass other economic influences other than the IMF programs.   Then the specific policies of the IMF and their objectives are compared to the resulting economic changes to see if the stated goals have been achieved via metrics. Also involved in this analysis is the ability of the Nigerian government to implement the changes required by the IMF.  Ã‚   This area of analysis is perhaps the easiest, as the initiatives of the IMF are easily available.   However, information on the implementation and the implementation’s challenges may be more difficult to find.   Looking at a timeline of IMF policies, one can also deduce what was effective or not effective.   If a policy was ineffective, then in a later cycle we should find a correction or an abandonment of the program. The internal structure of the government and economy can also be viewed.   The way that money flows and what directions can be measured.   It is important to see structural change since the 1980’s.   The Nigerian government worked with the IMF to develop the National Economic and Empowerment Development Strategy in 2004.[2]   This document reviews previous policy and also lays the groundwork for future work between the IMF and the Nigerian government. This report focuses on structural changes – highlighting the importance of revamping the Nigerian economy. Additionally, looking at the basic economic unit – the household – can show structural changes ass well.   By looking at these structural changes, the real question about revamping the economy can be answered.   Of course, this type of analysis also looks at the indirect effects of economic change.   These are difficult to measure, but by tracing newspaper stories and major events in Nigeria, it may be possible to trace events back to economic policy decisions. Overall, the question of the effectiveness of the IMF’s policies to restructure the Nigerian economy is a very important question with implications for future policy consideration and also a deeper understanding of the past. Now that the world is becoming smaller and national boundaries are being crossed with money and policy, it is more important than ever to understand the impact of economic policy.   Additionally, with the prevalence of capitalism and modernization, the effects of economic policy on third world nations must have a thorough understanding.

Argumentative Essay on Teen Pregnancy

Teenage pregnancy is a major issue in the United States. Some people say that this is society’s fault. Although having sex and getting pregnant is due to personal choices and decisions, there are a few things society could do to prevent it. Excessive teenage pregnancy could be controlled with appropriate media, more readily available birth control, and people to set good examples for young women. Just flipping through the channels on a Saturday afternoon you can see all sorts of inappropriate media full of sexual suggestions.Even aside from all the sex scenes in movies, there are shows SPECIFICALLY about teen pregnancy. Shows like Teen Mom and 16 and Pregnant make pregnancy seem acceptable and cool. If having sex at young ages didn’t seem like the cool thing to do, many teens wouldn’t do it. Taking inappropriate shows and movies off the air could make a difference in the teenage pregnancy rate. There are many forms of birth control.In a lot of arguments about tee n pregnancy there is talk about making condoms more readily available, but I think that other forms of birth control that are more consistently effective should be promoted instead. Condoms are important to use, but many times they can break or be ineffective. Plus let’s face it, in the heat of the moment lack of a condom doesn’t always keep sex from happening. Birth control pills are a cheaply made, more effective form of birth control. If forms of birth control such as the pill were cheaper and easier to get, more teens would be protected and less would get pregnant.The world in general is in need of good role models. Anyone that tweens and teens look up to should really try to focus on setting a good example. In a world full of bad examples, its especially important to set good ones for the group of people in that developmental stage. Teenagers need role models to protect them from falling victim to the pressures of today’s society, especially the sexual ones . In conclusion, I believe that teenage pregnancy is a very important issue.The sexual society of today’s America has resulted in a large increase in teen pregnancy. Programs that promote teen pregnancy and things that lead to teen pregnancy should be taken off every day television. Although it is going to be impossible to keep teens from having sex, making birth control extremely easy to use and get ahold of could have a huge effect on the teenage pregnancy rate. These two things along with good parental guidance and support, and good role models to look up to, would keep most teens from getting pregnant.

Lurhmann’s Romeo Essay

The first camera-shot is the television at a medium shot; we slowly zoom in, while the television image shows the names of the families, then a news reporter. This show’s the families are important to be on headline news. The female reporter says about half the prologue, when the camera stops zooming, but as she nears the end the camera zooms again. When she finishes he reading the camera zooms through the television quite rapidly. As it passes the screen it continues to zoom down the street extremely fast this also shows the films speed. The zoom comes to a stop and freezes for a few seconds and a big religious icon. This is the first sign of irony, because in the action packed film they still have time to notice God. The music is a choir with a loud volume, quick pace, it has a sinister tone because it is high pitched and quite quick it sound threatening, choir is high male voices to get the sinister speed and change of the notes. The voiceover starts and the music get quieter and drop behind the voiceover; it is still play but a lot quieter. A sound of a helicopter can be heard, the camera zooms out. It comes to the family tree of the two families of Capulet and Montague. The shot changes to fire, this symbolize war, anger and aggression between the two families. This is linked by the voiceover’s words of â€Å"From ancient grudge†¦Ã¢â‚¬  his voice sounds aggressive, this shows his anger. As he says the words headlines from newspapers appear. This show powerful families and modern times. These newspapers have heads like â€Å"Montague Vs Capulet†, â€Å"From ancient grudge†, â€Å"New Mutiny† and â€Å"Civil Blood makes civil hands unclean† These headlines appear as the voiceover says them. It shows the modern families that spans of a period of time. With the quick change of the headlines it shows us it is continually changing. There is a straight cut to two tall buildings with one has â€Å"Montague† on the other has â€Å"Capulet† with a holy icon in the middle. This show power on both sides and religion caught in the middle. This also shows irony that God is between the two feuding families. At this point the music gets louder to build tension. As the music gains momentum, there is a long shot of another religious icon to that they all believe in God. The music gets even louder as they show the characters. They begin with two men of the families; both are big stocky and powerful looking men, they both wear suit and shirt, the shirts are worn casually without a tie, they are big to represent that they are the head of the families. The women are very different; the Montague Lady is smartly dressed with neat hair. She looks a few years younger that her husband, she looks intelligent and mature. Lady Capulet is young, a lot younger than her husband, blonde with puffed out hair this is more stylish and so young age more. This also so that she is as mature or smart or tidy as Lady Montague. Prince is smartly dressed, with an angry face, he is the authority figure. Paris is smartly dressed this shows he is a business man, his vanity is show by his neat but floppy hair and his little smile. Mercustio is lively but can get angry shown by the close-up of his eyes with a mean, aggressive stare. There is a straight cut as the music gets louder and a series of fast cut images, mainly about violence and hatred between the families. The music climaxes then blends into a more drum beat. As a medium shot of a group of men, labeled â€Å"the Boys† The men are acting immature and acting like boys, by shouting and being a nuisance. There clothes are Hawaii shirts with the buttons undone which exposes there skinny bodies. This shows they are rude and obnoxious but are wimps if they were in a fight. A low shot is taken of the yellow car to stand out. A point of view shot of Benvolio goes off. The Capulet car arrives we get a low angle shot of the car coming towards us, this is to show they are threatening. One of the boys, who has pink hair, makes a stupid action. Abra is seen, there is an extreme close-up on Abra’s teeth of a metal plate. Abra is big muscular, this is show with his clothes which are tight on his body. Abra has an aggressive face and looks threatening and mean. Benvolio comes back, a close-up on his face as he pulls out a gun. Extreme close-up on the gun so we can see the name, nervousness can be seen in Benvolio’s face. Benvolio is big but not as muscular as Abra. There is silence when the camera cuts to Tybalt drops a match, there is a low angle shot to show Tybalt’s shoes, it shows he is flash because he has silver heals, he crushes the match, grinding it with his solid heal as it was an enemy, this is a very strong action symbolizing hatred and aggression. Tybalt has small cat like teeth, he is thin but toned and nimble. He wears black clothes which represents bad. Also he has two guns which show he is a good gun handler this also implies he is bad. He has slick hair and a little well groomed goatee which is a cat like feature. He has a red waist coat with an image of Jesus on, this shows irony that they fight but still believe in God.  Zeffirelli’s Romeo and Juliet is a tragic romantic story, I will tell you about the opening scenes of this video e.g. Voiceover, camera angles, characters, clothes and soundtrack. The voiceover is slow with a calm tone and a low pitch. They have this voice because it fits with the slow pace of the beginning of the film; the tone is calm, slow but upset. The music in the scene is of slow pace as well and links well with the slow pace of the voiceover. The soundtrack is hushed smooth rhythm with a slow and drowsy pace; this has high notes and a sympathetic sound. The music sounds like it was composed during the time of Shakespeare. Because the music is slow and if flows nicely with the text which is an old style italic font, this suggests that the film is set in along time ago as well as the music. We get a high-angle camera shot at the beginning which pans across the town smoothly and calmly like the music and the voiceover. The camera angle shows us a medieval town. The shot shows a river flowing in the middle of the town and all the colours are pastel and flow. The camera turns up and zooms slowly at the sun, it stops and it the big italic writing saying â€Å"William Shakespeare† as though his is the best. Straight cut to town’s court medium height angle, in the background a horse and cart can be seen this shows the period of time. There is a straight cut to the Montague boys feet, kicking a dog, this show them acting badly and causing trouble. There is a long shot on the Capulets they are dressed smartly and also polite. They wear darker coloured clothes to stand out. The Montague boys are dressed in bright clothes and stand out as well but they are rude. There is a straight cut to the Montague biting his thumb which is a close up, then a close-up on the people talking. Straight cut to towns people noticing trouble, then back to a medium shot of the Montague boys.
