The History Of Markup Languages Information Technology Essay

The History Of Markup Languages Information Technology Essay Document markup is a process of writing codes in a document to identify structure and format of a final appearance of a document. Markup was done by copy editor writing instruction on document that was followed by typesetter, before the computerization of printing industry. After computerization, text formatting languages were written. Copy editors markup was converted into the normal markup by a typesetter. When computers spread over the world, people began using word processing software to write documents. Each word processing program had its own feature and technique of markup. All electronic documents which store text use some form of markup. These markups can be visible, hidden or self-generated. Document markup divided into two categories specific markup and generic markup. Specific markup uses instructions which are specific to the certain software that produces document. Generic markup indentifies structure of a document. The beginning of generic markup was macros for typesetting language. Series of commands can be executed by software instruction which called macro. Furthermore, macro keeps track of chapter numbers in document and the change of macro can modify the feature of the chosen chapter. The first presentation about markup languages was made by William Tunnicliffe at Canadian Government Printing Office in 1967. Later in 1969 Raymond Lorie, Edward Mosher, and Charles Goldfarb created Generalized Markup Language (GML). GML was based on ideas of Tunnicliffe. In 1978 GML committee decide to make changes in markup and make it generic. They limited database searches to title by marking title as instead of and . It was a beginning of SGML which was based on both GML and Gencode. SGML was developed during the years and now it is used by major government agencies. HyperText Markup Language (HTML) is a markup language that creates web pages. Nowadays, all web pages are made by using HTML or another language which uses basic elements of HTML. Since 1990 when Tim Berners-Lee invented HTML, this markup language started to advance and now it is the most primary language in a world of web. HTML developed from HTML 1.0 to HTML 4.0 in 7 years. In 1994, first HTML 2.0 document was released First draft HTML 3.0 was released in 1995 In 1996, HTML 3.0 was developed to HTML 3.2 HTML 4.0 was released later in 1997. HTML 4.0 is the current version of HTML. -XML XML was created in 1996 by XML Working Group which was lead by Jon Bosak. The design goal of XML was: XML should be easily accessible over the internet Various applications must be supported by XML XML should be similar to SGML. SGML is another markup language which was created before SGML. More precise information about SGML will be given in the next section XML should be designed brief and official. It should be easy for beginners to create documents in XML XML, Extensible Markup Language, is a standard for document markup which is supported by World Wide Web Consortium (W3C). XML is markup language and a restricted form of Standardized General Markup Language (SGML) which provides a standard format for electronic documents. This format can be easily customized for web sites, vector graphics, object serialization and voice-mail systems. Programs which control data in XML documents can be written by users. So, the availability of libraries in different languages that can write and read XML, allows users to concentrate on the unique needs of their program. Moreover, XML documents can be modified using text editors and web browsers. Data of XML is included as strings of text in this type of documents. XML and HTML documents look similar. However; there are some important differences. First of all, XML is a matemarkup language. That means XML provides sets of elements and tags that can work for everybody in different areas of interest. For example, Chemists can use molecules, atoms and reactions by using appropriate elements. Musicians can use elements notes, lyrics and much more that concerns their job. XML is a language that can be adapted to meet different requirements. Basic unit of data of XML is called an element. XML identify how elements surrounded by tags, the specification of tags and the names which appropriate for elements. The documents which satisfy these requirements are successfully formed; Otherwise documents containing errors will be rejected by XML. Documents in XML are compared with specific scheme. If a document matches scheme then this document considered valid. Invalid documents are not equivalent to scheme, but it is not important for all documents to be valid. There are various XML schemes. Document type definition (DTD) is the mostly supported scheme which is the only scheme that supported by XML 1.0. DTD contains the entire legal markup and identifies places where these markups can be inserted in the document. -SGML Worldwide standard for the explanation of device-independent, system-independent ways if representing texts in electronic form called Standard Generalized Markup Language (SGML). SGML documents are not limited by size and can form an independent unit that transported either electronically or in printed form. SGML documents contain interconnected elements that hold data serving for specific purpose. Document Type Definition (DTD) characterizes documents structure according to the elements it contains and the order of these elements. DTD is linked with a SGML. Within the DTD each element in the document named in order to recognize the role of this element. The recognized elements can form the tags that identify the start and the end of elements, when they placed within markup delimiters. SGML parses must authorize files that positioned into the repository. SGML system can be constructed from interrelated software components. Data repository is a central part of SGML system. Before the documents are dispatched from the repository another validation needed in order to guarantee that referenced data has not been neglected from the transmitted data set. SGML documents can be formatted according to features required by the author. There is a standard for defining: the structure of documents classes; characters for markup, and in the text of document; common text that will be written; special marking up techniques like tag minimization or identification of various versions of document; Attributes qualify some SGML markup tags. These attributes can help to identify specific tags, recall data that is externally stored and indicate the role of elements. Moreover attributes can control the way of presenting text to readers. SGML not only make easy to associate feature to text by short form of tags, but also named character references can be used to demand characters that are not included in character set of word processor. In order to modify SGML-coded document, it needed to be converted into form that word processors can understand. It is a complex process for generalized SGML document and there one application which is specifically designed for converting word -processed text into and out of SGML. This application is called HyperText Markup Language (HTML) that is used on the World Wide Web. -HTML and XHTML HyperText Markup Language (HTML) is the computer program that allows user to create own web page by formatting text and present it to the Internet public. First of all, hypertext and universality are the main qualities of HTML. Hypertext means that it possible to insert a link in a webpage that leads to another webpage. So, it is possible to access information on the internet from various places. Secondly, HTML is universal language, because these types of documents can be accessed from any computer such as Macintosh, UNIX and Microsoft. Special programs were designed in order to read HTML pages. These programs called browsers and the popular ones are Mozilla Firefox, Internet Explorer, Netscape operator and Opera. XML looks like HTML language; However , XML is a language that not only helps to create web pages, but also the program by which author can create his custom markup language to format documents. By using XML It is possible to use written data as custom information and used it further in the text. Nevertheless, XML is not as merciful as HTML. XML need careful coding, since XML is sensitive to upper and lowercase letters, quotations and tags. There is a huge number of HTML pages that can be read by any browser. So, World Wide Web Consortium (W3C) decided to write HTML in XML. This new invention that called XHTML had all features of HTML as well as XMLs power and flexibility. -TEX There are two different categories of text processors: WYSIWYG (what you see is what you get) system. User can see exactly what his document will look like while typing text. Markup system, Authors type text scattered with formatting commands, but they are unable to see appearance of their document while working on text. In order to see final result user must run the program. Since the final product can be seen by author, WYSIWYG systems have the obvious advantage; however, person can easily be distracted by the appearance of the document and will be unable to write the paper effectively. Because of these reasons, people who want academic paper prefer markup systems. TEX is an example of the markup system that was built in early eighteens, before WYSIWYG systems were widespread. Advantages of TEX TEX documents formed by the help of macros, that define format of each component. By the help of macros users dont have to write unnecessary formatting commands. For example, in order to write a footnote it is enough to write footnote command, instead of moving text to the bottom of page. Macros make TEX flexible. By changing definition of certain macro, the appearance of a document can be changed. TEX is easily adaptable, since new commands can be created. In order to print document which is written in TEX, user needs to give the output to a driver program which will convert descriptions into commands that understood by printers. Tex is doesnt rely on technology of printers; you just write a new driver when technology changes. TEX is freely available over the internet. TEX is an ideal program to create academic papers and even books. Disadvantages of TEX First of all, beginners have difficulty at getting used to TEX programming. It is easy to write primary macros, but writing complex macros is not a beginners work. Moreover, memory and design of TEX is limited, it doesnt grow dynamically and it uses only its own fonts. The most spread problem is interactivity of TEX. However, there is a solution to this problem. Many programs that give additional features to TEX are available. For example, Macintosh users can access the program named TEXtures that helps user to: Edit multiple texts at the same time with a multi-window editor; View the output of the program on the screen by the help of previewer; A printer driver; TEX proper. PC clone users can only edit one text at a time. User, should first of all edit a file, then run this document by the help of TEX, afterwards use previewer in order to see the output on the screen. If there are mistakes in the text user must write all of them down then edit file again. Nowadays, most common used systems are WYSIWYG programs that use a TEX engine. User can easily change appearance by few mouse clicks without having any knowledge about TEX.

Introduction to Santería :: Santeria

Introduction to Santerà ­a Santerà ­a, sometimes referred to as La Regla Lucunmi, originated in West Africa in what are now Nigeria and Benin. Santerà ­a is, however, not purely a West African religion; it has many ties to European Catholicism. Because of this correlation, there is no exact year for the formation of this religion. The closest date available for the founding of Santerà ­a is between the 1700's to about 1870 – the period of the slave trade. The slave trade brought many people that practiced this particular religion to the shores of Cuba, Haiti, Puerto Rico, Trinidad as well as many other Caribbean countries. Not only were the slaves' bodies brought over. Their souls, culture, and religion were brought to the Americas as well. In the early years, when the slaves had just begun arriving, there was a great deal of pressure placed on them, by the European plantation owners and missionaries, to convert to Catholicism. Despite these attempts by the plantation owners, Santerà ­a was still openly practiced, and the number of practitioners was increasing. Since in performing openly their religion many harsh beatings and punishments were administered, the religious followers tended to incorporate many Catholic elements into their religion. One factor that helped to make the two religions look similar to the plantation owners was that many of the orishas, the primary gods, shared many of the same physical characteristics that the Catholic saints possessed. This made the slaves appear to be practicing Catholicism although they were practicing their native, African religions. Believers of Santerà ­a place their faith in the orishas. The orishas are not as powerful or as omnipotent as their predominant God, Olodumare, or Olorun. Olorun is the source of ashe, the spiritual energy that makes up the entire universe, all life and all things material. The orishas are the spirits or gods that interact with humans by controlling nature and attending to the daily needs of the religion's followers. They are approachable and can be counted on to come to the aid of followers by guiding them to a better life, materially as well as spiritually. In other words, they are emissaries of God. Furthermore, each orisha possesses a distinct personality. Communication between orishas and humankind is accomplished through ritual, prayer, divination and offerings (ebo). Depending on the particular orisha that they wish to please, santeros use certain colors and certain animals and play particular drumbeats during their rituals. The music is of great importance because it helps to coax the orisha into "mounting" or possessing the priest.

Wealth and Greed - Do You Suffer from Affluenza? :: Argumentative Persuasive Essay Examples

Affluenza: A Human Created Disease With Profound Consequences Chances are that you haven't come across the disease known as affluenza, even if you have been an avid reader of newspapers and listener of news broadcasts. It is possibly the least discussed of the more debilitating diseases of our time. Strangeness characterizes this disease in many other ways too. Almost every one of us actively carries it. Its effects impact not only the immediate carrier but also society at large. Its symptoms are so commonplace that few people make a connection between the disease and the discomfort that it breeds. It infects rich and poor alike, and is beginning to imbed itself in younger and younger carriers. Oddly, those that do recognize the scourge that it sometimes brings are disparagingly referred to as hypocrites, elitists, party-poopers, or catastrophists. And most confusing, it is a disease that is socially acceptable among many of us. Wow, what a bizarre disease, huh? Yet, fortunately, known cures exist for this disorder but they require our dedicati on and perseverance to eradicate this pernicious malady. Defined by authors of a book with the same title, Affluenza is "a painful, contagious, socially transmitted condition of overload, debt, anxiety, and waste resulting from the dogged pursuit of more" (de Graaf et al.). In simple terms, affluenza is a disease that many of us suffer because we are too fixated on buying and consuming more and more. Do you think you or others you know might have it? But how would you know if you have it? What are the signs of this disease? According to some, affluenza is so encompassing in its effects on our psyches and our bodies that many symptoms of it do not appear different other more common disorders. Other symptoms are more easily distinguishable. Rather than spell out each symptom one by one, let's determine the extent to which you might have this disease through a series of questions. Answer the following questions with yes or no answers: 1. When you find yourself in a depressed mood, do you often get an impulse to buy something to soothe yourself?; 2. Do you often pay close to the minimum payment on your credit cards because of lack of available funds? 3. Do you work a job (either a 2nd job or an additional job to your spouse's) in order to afford the "luxuries" in life?; 4. Do you spend holidays with family members in facilities designated for consuming products-e.

Positivism And The Real :: essays research papers

Positivism is a trend in bourgeois philosophy, which acknowledges the orthodoxy towards empirical knowledge of natural phenomena where metaphysics and theology are regarded as inadequate and imperfect systems of knowledge. Positivism, began to rise as the main intellectual movement during the second half of the 19th century in response to the inability of speculative philosophy, witch was indeed Romanticism.   Ã‚  Ã‚  Ã‚  Ã‚   During the first half of 19th century, the Romanticism brought new views that helped the civilization of that time reach a higher level but it also brought the negative side effects. It brought the chaotic effect that people started in a extremely liberal way to threat the social order in the increasing dispute of 1847 to 1848 which was posed not just by revolutions but by the eruption of an insidious, continually growing, struggle of class against class. The imperceptive economic thoughts, as those in France of Pierre-Joseph Proudhon, eloquent if inconsistent writer, denounced the property classifying it as theft. The revolutions of 1848 lead the way for European thinkers to develop new visions for the way of thinking that brought to the idea of Positivism.   Ã‚  Ã‚  Ã‚  Ã‚  Claude Henri de Saint-Simon, French socialist/philosopher, conceived the idea of a new science of society that would result in the economic and intellectual emancipation of man. Saint-Simon thought that the new idea must be a positive philosophy based on experience and science. Another Frenchman Auguste Comte, who is considered the founder of Positivism, was the first to introduce the term â€Å"positivism.† According to Comte, the new natural sciences indicated that a new social science should be built on observation and experience. Comte also described the human history as a three-staged chronology of progress, with each stage having a different social organization based on the social environment of the time, with action based on different principles at each stage. Those were the theological stage, metaphysical stage and at last the positive era.   Ã‚  Ã‚  Ã‚  Ã‚  After its birth in France, positivism continued to spread to England where it obtained a new and better form. In fact, it was in England that the biggest positivist arose. James Stuart Mill, a writer on economy, was one of the main figures in English positivism. In his largely influential System of Logic (1843) Mill introduced the logical positivism that declared: all discoveries of truth not self-evident consist of inductions and the interpretation of inductions. Mill’s theory of logic is based on the laws association.

Kant & ontological proof

The basic principles of ontology are argument for existence of God as a predicate and argument for God’s existence as a necessary existence. The first leg of the argument states: God is the greatest and most perfect being that can be conceived. Existence in imagination and reality is greater than existence in imagination only. Therefore, God really exists. The second leg of the argument is that: God is the entity than which nothing greater can be conceived. It is greater to be necessary than not. God must be necessary. God necessarily exists.Kant’s objection to conceived God as proof of his actual existence is premised on the ability of everything that is said to exist to have some features or characteristics attributable to them. He argued that existence is not a property or the constituent of a thing. Anything that has the property of being non-existent cannot possibly have any other property.  David Hume’s objection is that nothing can be proved a priori. Pr oving a priori is through an opposite contradiction. The resultant contradiction makes something inconceivable. Nothing can be proven a priori, since it is impossible to comprehend anything not existing.Norman Malcolm, in defending the idea of God, maintains that while it may be true that existence of God as a predicate for his reality may be unsustainable, he calls attention to another twist of the argument, which is necessary existence. He argues that where the idea of God, greater than which nothing can be conceived, is possible, it is therefore logically consistent that He necessarily exists. I agree with Malcolm. God must necessarily exist so that the existence of other beings can be traced to Him, who in himself is self existent.REFERENCE.1.

Comparison and Contrast Between Love

First love can happen at any age or not happened at all, but must people have fallen in love for the first time as a teenager or an adult. First love is an exciting new experience that most people remember very well as something naive, impulsive and unforgettable love. However, forever love is one of the strongest emotions that a human being can feel. It can arise ever so intensely, spreading a feeling of warm happiness through every inch of a person body like a wild fire spreading through a tree.As the feelings become more intense, the flame of passion can turn into a blazing fire that burns strongly through every ventricle of a person’s heart. This love makes one committed to stay in the relationship for the long haul. When it comes to first love and forever love, these two loves are different in regard to communication, unconditional support and emotional support. Forever love requires romantic partners to communicate even when it is hard to come to an agreement. Instead of walking out of the house without talking or going to bed angry, partners stay up late until the differences and problems are reconciled.For instance, on the Cosby show, Clare and Bill would have disagreements when difference arose. The differences would be how to discipline the children, Bill not eating healthy meals or not listening to one another. Instead of Bill and Clare yelling and pointing the finger at one another, they would communicate without playing the blame game and apologize to one another regardless of who is right. I know one might say they are playing characters on a television show, but one cannot disagree that forever love lays out the foundation of how to compromise and respect one’s life partner.Forever love also shows unconditional love and support by showing devotion and understanding of one another. For example, Diane Reeves showed her husband Christopher Reeves unconditional love and support when he was paralyzed. She never viewed him as a patient bu t as the love of her life. She always supported him through grueling physical therapy sessions and surgery. By her being so extremely devoted, she never deserted him when he was paralyzed or stayed with him out of pity. She truly, madly and deeply loved him regardless of his disability.My husband, James, is my forever love because he supports me in my goal of pursuing an associate degree in Health Service Management. My forever love does this by telling me how well I am accomplishing my goals by getting good grades in school. Whenever I am feeling overwhelmed and frustrated after a long day of classes and working, he gives me words of encouragement. He tells me that he has faith in me because he knows I will succeed. By doing this, he gives me the support I need to achieve my educational goals. On the other hand, first love relationship disagreements are inevitable.But how are they handled? Instead of reconciling their difference, conversation are battlegrounds where viewpoints are defended with grim determination and words are weapons instead of tools of communication. In the heat of anger, complaints are expressed in a destructive fashion which causes romantic partners to say, â€Å"See you later,† because one is not fully committed to the relationship. For example, my first love, Ernest, and I would argue all the time and never reconciled our differences because we each wanted to be right.We tried to make the relationship work but we were so naive about love that we ended the relationship because neither one of us was committed enough to make it work. Another difference between first and true love is unconditional love and support. With first love, this type of love is not strong because one is not fully committed to the relationship. For instance, Judy, my friend, and her first love, Jim, were inseparable. Judy and Jim were dating for six months. They would go to the movies, parties, and sports games for fun until a tragedy happened.Jim was involved in an automobile accident that left him paralyzed from the waist down. Instead of showing unconditional love and support for her romantic partner, she left him because she could not handle his disability. She was not committed enough to him or their love to support Jim in his time of need. First love is not as strong as forever love because this is a new experience and the partner is not concerned with a long, strong commitment. In conclusion, Love does not long for power; it does not want to be hurt or be punished for mistakes.It is self-sacrificing because it is ready to forgive partners over and over again. It is wrong to think that love is always suffering; it only means that one takes a person as he or she is and does not expect a romantic partner to be perfect. Forever love is more invested in keeping the relationship intact because one is willing to reconcile his or her differences, and show unconditional love and support but most of all communication. This love makes partne rs stand by each other side through tragedies and difficulties, whereas first love has little willingness to commit to the relationship.

Value Chain

Value Chain Analysis ******** Diagram ********* The above model demonstrates the principal element of Value Chain Analysis for an organization such as Easyjet. The integration of the above elements ultimately delivers great margin potential and thus the ideal high profitability status. I will provide a detailed analysis of this model to highlight the core capabilities of Easyjet: Infrastructure Main headquarters based in Luton. Provides excellent communication with motorways, railway lines and bus access Low overheads Paperless office No ticketing system with posted ticket Simple distribution channel management (through the Internet or call centers) Low airport costs (minimal time of aircraft on the ground), thus achieving economies of scale Financial resource investment initially supported by Haji-loannou HR Management Haji-loannou, high profile entrepreneur (shipping tycoon background), Hands-on-approach from Haji-loannou – looking for opportunities to diversify and expand, Innovative marketing terms for marketing communications to date. Technology Development Booking through the Internet (higher margins, with a more manageable, simplistic system) Strong reputation for being an airline where bookings are made via the phone or Internet. Procurement Easy purchase system in place for flight bookings Negotiated low cost airport fees Simple staff uniforms No tedious ticketing system in place Below you will find a commentary on how these key elements are also integrated into the Easyjet business and further, how the strengths can be used to develop and extend the Easyjet brand. Inbound Logistics Excellent communication system in place at airports and easy flight booking policy/payment methods convey an image of convenience – a key benefit to consumers Operations and Outbound Logistics Good marketing strategy – ‘we have the best’ approach Partnerships and promotional tie-ins with the mass media High profile PR strategy (for example: the PR stunt against Robert Ayling, Chief Executive of British Airways and its budget airline â€Å"GO† – gains cheap PR coverage) Fine targeting of attractive segments emerging e. . utilization of casual uniforms. However, safety is always a critical concern and is up to par with the standards of other airlines. Service Convenience and simplicity are of integral importance Affordable, frequent, reliable, safe slots are offered to an increasing number of new destinations No frills and/or complications are associated with the travel experience. Conclusion Clearly Easyjet has some at tractive core capabilities that have been established in the marketplace and are perceived as ultimately beneficial to the consumer. The Value Chain Analysis highlights those elements of the business that can be integrated or fine-tuned (through for example ‘just in time’ systems, quality standards and relationship marketing) in order to achieve the overall objectives of high margins, profitability and market share. Perceived superior services or products, market knowledge, industry contacts, legal advantages (patents, copyrights) perceived high value brands, low overheads, economies of scale and an offensive marketing approach are some of the key factors / elements for sustaining a competitive advantage and indeed promoting the Easyjet family of companies.
