The saxophone is a very misunderstood instrument. When it is mentioned, the typical person thinks of jazz, pop, or rock of the 20th century. The saxophone, although a huge part of the 20th century "radio" genre, was and still is part of the classical repertoire. The instrument itself is very popular, and it is very common to have a wind band with several saxophone players. It is found most often in jazz ensembles. But, the saxophone was invented in 1840, and jazz did not show up until the 20th century. The saxophone was around well before jazz musicians Charlie Parker, Lester Young, and Paul Desmond were alive. So, what was the purpose of the classical saxophone? Where did it come from? Adolphe Sax could not have imagined the popularity of his invention at the time that he patented it. He was born in Dinant, on the Meuse River. This Belgium city was once under French rule. Sax's father was an architect and a musician. He enjoyed tinkering in his father's shop, always trying to build or invent something. His father encouraged this, and without this encouragement, the saxophone may have not been invented until many years later. His first musical experiences were good ones, and being very fluent in woodwinds, he began to notice intonation problems with clarinets. He would tinker with them trying to improve on the instrument. Had Sax not been so content with improving on instruments, he surely would have been a virtuoso clarinetist. At the age of 14 he showed much potential, but his true love was working on the instruments.
By the time he was 16, he had already been recognized for his improvements on the clarinet. He entered many shows and competitions showing his improved instruments. Still, he was not satisfied. He wanted something new and exciting. He came upon the idea of having a conical brass instrument that produced a sound with a reed, like a clarinet. By 1840 he had built his first saxophones. He entered the 1841 Belgium Exhibition.

Today one of the most cherished ideologies of America is the fact that everyone is and should be created equal. With this cherished ideology bringing a sense of pride and diversity to America we must keep in mind that this cherished ideology did not always exist. Since 1865 various individuals and groups have not been able to receive and express their rights to full equal status in the United States. These different individuals and groups have seemingly fought for their rights in equality and have become pioneers in the fight for evolution for equality. In 1865 African Americans in the United States under the 13th amendment were freed from the terrible burden of slavery. Through the 14th amendment they were given the right to citizenship and the right to equal protection. The 15th amendment gave them the right to vote regardless of their skin color race or any other type of servitude. These amendments were meant to be enforced and make a serious change in the everyday life of the average American. With these amendments passing in 1865 they were meant to make a serious change towards the evolution of equality. These changes did not seem to happen right away and African Americans were still not being treated with equality. The average African American at this time were being denied there newly given rights every day making life extremely hard to stay.

Shackleton’s Way: Analysis & Review Sara Mleso Weber State University Shackleton’s Way: Analysis & Review Unfortunately, I missed the opportunity to participate in the group discussion in person on the day we were on campus. I have since emailed both particpants in my group, Anna Guzman and Tara Rhodes, who both responded promptly that everyone was submitting short answers to the questions in our discussion group, to compare and analyze. I have since compared and reviewed their answers with mine and we have similar opinions on Shackleton’s leadership traits, the meaning of the great achievement of failure to us all seemed to be that his greatest achievement was successfully keeping his team of men alive for two years. Not only did he keep them alive, they were for the most part happy and positive until the end. I think we also all agreed that leading by example was the greatest motivator he gave to his team. People are more likely to do what you ask if they see you alongside of them working just as hard. Learning about Shackleton has been one of the most enjoyable parts of my BSN education and I look forward to researching and learning more about him. Leadership Trait Shackleton possessed many leadership traits that I am still in awe of after reading this book. He was thoughtful, organized, determined, and passionate to name a few. The trait that stands out the most that sets him apart is flexibility. He planned for months, even years.

Name: Andiswa Mlambo Student no:48090239 Unique number: 844868 Assignment. 04 Question 1 The reform of Alexander11 [1855-1881] were meaningless and left tsarist Russia unchanged ; do you agree? Give reasons for your answer. I agree that the reform of Alexander11 [1855-1881] were meaningless and left tsarist Russia unchanged. The disastrous state of affairs left by Nicholas I meant that change had to come to Russia. His son, Alexander II was responsible for introducing major changes to the social system and other important aspects of life in Russia. Because of this, the reign of Alexander II was one of the most important periods in Russian history . Many historians believe that if Alexander II had been prepared to grant moderate political concessions, along with his social, legal and military reforms, Russia might have gradually become a constitutional monarchy. But although Alexander did tackle the urgent problem of serfdom, his reforms did not go far enough and he too was determined to hang on to his autocratic power. After the defeat in the Crimean War many Russians now realised that Russia's only hope for military survival lay with modernisation. This would mean industrialisation to supply the military, improvements to communications and the introduction of a railway system. Financial reforms were introduced to meet the needs of the government not of the private sector. In 1860 Alexander II established the State Bank to provide credit.

was very worried about my name in the US because it has another meaning, I do not want people to make fun of my name when they pronoun it. But then, nothing happens, people in there do not care who am I, how I look or treat me in different ways. I realized in there has so many races of people who come from other countries and they treat each other equally. To be honest, I not really like Black African Americans much because I think they always annoy, but not because of that reason I treat them not equally or have bad attitude toward them! This is the first time I had heard about Latino. It is really a new knowledge for me. Although I am very confused and did not understand all of thing about Latino, I still enjoy and interested in their history . According to the book “Harvest of Empire-Juan Gonzales,” it said: “…Latinos numbered a mere 9.1 million and represented just 4.5 percent of the population as recently as 1970.” (Juan Gonzalez, p.16) In my opinion, when Latino immigrates to the US with a huge amount, they all bring to the US a new culture, new race, new physical characteristic, etc. For example, the popular music in the US at that time was Latin music. “But now Latino migrant, the product of those old relationships, have invaded the North American garden, kitchen, and living room. We are overflowing its schools, its army, even its jails.” (Juan Gonalez, p.18) In another side, Latino also brings immigrant different skin color in the US and that made.

How accurate is it to suggest that the treaty of Versailles was mainly responsible for the political and economic instability in Germany in the years 1919-1923? Practice Essay Samual Brown How accurate is it to suggest that the Treaty of Versailles was mainly responsible for the political and economic instability in Germany 1919-23?The political effects of the Weimar republic were as follows, that the Versailles diktat was “a blow in the face” to Germany political and economy recovery. They also thought it was a dark shadow on the new political order. There was also a demoralisation which the treaty caused. The peace settlement “poisoned” the political atmosphere. Weimar was a diktat that was going to undermine the rebuilding process of the Weimar republic. The constitution created a parliamentary structure and a voting system that was going to be taken advantage of by the anger and bitterness of the Weimar agreeing to the treaty of Versailles. In regards to politics the Germans saw the government as the “November criminals” who stabbed them in the back. The 1919 Treaty of Versailles led to great political and economic instability as the government was seen by many to surrender to the dictation of Britain, France and America. Forcing the huge submission of Germany's land, resources and military capability, the Treaty of Versailles certainly played an important role in causing the political and economic instability witnessed during 1919-23. However, the.

In real-life applications, you will want to use the SAX parser to process XML data and do something useful with it. This section examines an example JAXP program, SAXLocalNameCount. that counts the number of elements using only the localName component of the element, in an XML document. Namespace names are ignored for simplicity. This example also shows how to use a SAX ErrorHandler .
Note - After you have downloaded and installed the sources of the JAXP API from the JAXP download area. the sample program for this example is found in the directory install-dir/jaxp-1_4_2-release-date/samples/sax. The XML files it interacts with are found in install-dir/jaxp-1_4_2-release-date/samples/data .Creating the Skeleton
The SAXLocalNameCount program is created in a file named SAXLocalNameCount.java .
Because you will run it standalone, you need a main() method. And you need command-line arguments so that you can tell the application which file to process.Importing Classes
The import statements for the classes the application will use are the following.
The javax.xml.parsers package contains the SAXParserFactory class that creates the parser instance used. It throws a ParserConfigurationException if it cannot produce a parser that matches the specified configuration of options. (Later, you will see more about the configuration options). The javax.xml.parsers package also contains the SAXParser class, which is what the factory returns for parsing. The org.xml.sax package defines all the interfaces used for the SAX parser. The org.xml.sax.helpers package contains DefaultHandler. which defines the class that will handle the SAX events that the parser generates. The classes in java.util and java.io. are needed to provide hash tables and output.Setting Up I/O
The first order of business is to process the command-line arguments, which at this stage only serve to get the name of the file to process. The following code in the main method tells the application what file you want SAXLocalNameCountMethod to process.
This code sets the main method to throw an Exception when it encounters problems, and defines the command-line options which are required to tell the application the name of the XML file to be processed. Other command line arguments in this part of the code will be examined later in this lesson, when we start looking at validation.
The filename String that you give when you run the application will be converted to a java.io.File URL by an internal method, convertToFileURL(). This is done by the following code in SAXLocalNameCountMethod .
If the incorrect command-line arguments are specified when the program is run, then the SAXLocalNameCount application's usage() method is invoked, to print out the correct options onscreen.
Further usage() options will be examined later in this lesson, when validation is addressed.Implementing the ContentHandler Interface
The most important interface in SAXLocalNameCount is ContentHandler. This interface requires a number of methods that the SAX parser invokes in response to various parsing events. The major event-handling methods are: startDocument. endDocument. startElement. and endElement .
The easiest way to implement this interface is to extend the DefaultHandler class, defined in the org.xml.sax.helpers package. That class provides do-nothing methods for all the ContentHandler events. The example program extends that class.
Note -DefaultHandler also defines do-nothing methods for the other major events, defined in the DTDHandler. EntityResolver. and ErrorHandler interfaces. You will learn more about those methods later in this lesson.
Each of these methods is required by the interface to throw a SAXException. An exception thrown here is sent back to the parser, which sends it on to the code that invoked the parser.Handling Content Events
This section shows the code that processes the ContentHandler events.
When a start tag or end tag is encountered, the name of the tag is passed as a String to the startElement or the endElement method, as appropriate. When a start tag is encountered, any attributes it defines are also passed in an Attributes list. Characters found within the element are passed as an array of characters, along with the number of characters (length) and an offset into the array that points to the first character.Document Events
The following code handles the start-document and end-document events:
This code defines what the application does when the parser encounters the start and end points of the document being parsed. The ContentHandler interface's startDocument() method creates a java.util.Hashtable instance, which in Element Events will be populated with the XML elements the parser finds in the document. When the parser reaches the end of the document, the endDocument() method is invoked, to get the names and counts of the elements contained in the hash table, and print out a message onscreen to tell the user how many incidences of each element were found.
Both of these ContentHandler methods throw SAXException s. You will learn more about SAX exceptions in Setting up Error Handling .Element Events
As mentioned in Document Events. the hash table created by the startDocument method needs to be populated with the various elements that the parser finds in the document. The following code processes the start-element and end-element events:
This code processes the element tags, including any attributes defined in the start tag, to obtain the namespace universal resource identifier (URI), the local name and the qualified name of that element. The startElement() method then populates the hash map created by startDocument() with the local names and the counts thereof, for each type of element. Note that when the startElement() method is invoked, if namespace processing is not enabled, then the local name for elements and attributes could turn out to be an empty string. The code handles that case by using the qualified name whenever the simple name is an empty string.Character Events
The JAXP SAX API also allows you to handle the characters that the parser delivers to your application, using the ContentHandler.characters() method.
Note - Character events are not demonstrated in the SAXLocalNameCount example, but a brief description is included in this section, for completeness.
Parsers are not required to return any particular number of characters at one time. A parser can return anything from a single character at a time up to several thousand and still be a standard-conforming implementation. So if your application needs to process the characters it sees, it is wise to have the characters() method accumulate the characters in a java.lang.StringBuffer and operate on them only when you are sure that all of them have been found.
You finish parsing text when an element ends, so you normally perform your character processing at that point. But you might also want to process text when an element starts. This is necessary for document-style data, which can contain XML elements that are intermixed with text. For example, consider this document fragment:
<para> This paragraph contains <bold> important</bold> ideas.</para>
The initial text, This paragraph contains. is terminated by the start of the <bold> element. The text important is terminated by the end tag, </bold>. and the final text, ideas.. is terminated by the end tag, </para> .
To be strictly accurate, the character handler should scan for ampersand characters (&) and left-angle bracket characters (<) and replace them with the strings & or <. as appropriate. This is explained in the next section.Handling Special Characters
In XML, an entity is an XML structure (or plain text) that has a name. Referencing the entity by name causes it to be inserted into the document in place of the entity reference. To create an entity reference, you surround the entity name with an ampersand and a semicolon:
When you are handling large blocks of XML or HTML that include many special characters, you can use a CDATA section. A CDATA section works like <code>. </code> in HTML, only more so: all white space in a CDATA section is significant, and characters in it are not interpreted as XML. A CDATA section starts with <![[CDATA[ and ends with ]]> .
An example of a CDATA section, taken from the sample XML file install-dir/jaxp-1_4_2-release-date/samples/data/REC-xml-19980210.xml. is shown below.
<p><termdef id="dt-cdsection" term="CDATA Section"<<term>CDATA sections</term> may occur anywhere character data may occur; they are used to escape blocks of text containing characters which would otherwise be recognized as markup. CDATA sections begin with the string "<code><![CDATA[</code>" and end with the string "<code>]]></code>"
Once parsed, this text would be displayed as follows:
CDATA sections may occur anywhere character data may occur; they are used to escape blocks of text containing characters which would otherwise be recognized as markup. CDATA sections begin with the string "<![CDATA[ " and end with the string "]]> ".
The existence of CDATA makes the proper echoing of XML a bit tricky. If the text to be output is not in a CDATA section, then any angle brackets, ampersands, and other special characters in the text should be replaced with the appropriate entity reference. (Replacing left angle brackets and ampersands is most important, other characters will be interpreted properly without misleading the parser.) But if the output text is in a CDATA section, then the substitutions should not occur, resulting in text like that in the earlier example. In a simple program such as our SAXLocalNameCount application, this is not particularly serious. But many XML-filtering applications will want to keep track of whether the text appears in a CDATA section, so that they can treat special characters properly.Setting up the Parser
The following code sets up the parser and gets it started:
These lines of code create a SAXParserFactory instance, as determined by the setting of the javax.xml.parsers.SAXParserFactory system property. The factory to be created is set up to support XML namespaces by setting setNamespaceAware to true, and then a SAXParser instance is obtained from the factory by invoking its newSAXParser() method.
Note - The javax.xml.parsers.SAXParser class is a wrapper that defines a number of convenience methods. It wraps the (somewhat less friendly) org.xml.sax.Parser object. If needed, you can obtain that parser using the getParser() method of the SAXParser class.
You now need to implement the XMLReader that all parsers must implement. The XMLReader is used by the application to tell the SAX parser what processing it is to perform on the document in question. The XMLReader is implemented by the following code in the main method.
Here, you obtain an XMLReader instance for your parser by invoking your SAXParser instance's getXMLReader() method. The XMLReader then registers the SAXLocalNameCount class as its content handler, so that the actions performed by the parser will be those of the startDocument(). startElement(). and endDocument() methods shown in Handling Content Events. Finally, the XMLReader tells the parser which document to parse by passing it the location of the XML file in question, in the form of the File URL generated by the convertToFileURL() method defined in Setting Up I/O .Setting up Error Handling
You could start using your parser now, but it is safer to implement some error handling. The parser can generate three kinds of errors: a fatal error, an error, and a warning. When a fatal error occurs, the parser cannot continue. So if the application does not generate an exception, then the default error-event handler generates one. But for nonfatal errors and warnings, exceptions are never generated by the default error handler, and no messages are displayed.
As shown in Document Events. the application's event handling methods throw SAXException. For example, the signature of the startDocument() method in the ContentHandler interface is defined as returning a SAXException .
public void startDocument() throws SAXException < /*. */ >
A SAXException can be constructed using a message, another exception, or both.
Because the default parser only generates exceptions for fatal errors, and because the information about the errors provided by the default parser is somewhat limited, the SAXLocalNameCount program defines its own error handling, through the MyErrorHandler class.
In the same way as in Setting up the Parser. which showed the XMLReader being pointed to the correct content handler, here the XMLReader is pointed to the new error handler by calling its setErrorHandler() method.
The MyErrorHandler class implements the standard org.xml.sax.ErrorHandler interface, and defines a method to obtain the exception information that is provided by any SAXParseException instances generated by the parser. This method, getParseExceptionInfo(). simply obtains the line number at which the error occurs in the XML document and the identifier of the system on which it is running by calling the standard SAXParseException methods getLineNumber() and getSystemId(). This exception information is then fed into implementations of the basic SAX error handling methods error(). warning(). and fatalError(). which are updated to send the appropriate messages about the nature and location of the errors in the document.Handling NonFatal Errors
A nonfatal error occurs when an XML document fails a validity constraint. If the parser finds that the document is not valid, then an error event is generated. Such errors are generated by a validating parser, given a document type definition (DTD) or schema, when a document has an invalid tag, when a tag is found where it is not allowed, or (in the case of a schema) when the element contains invalid data.
The most important principle to understand about nonfatal errors is that they are ignored by default. But if a validation error occurs in a document, you probably do not want to continue processing it. You probably want to treat such errors as fatal.
To take over error handling, you override the DefaultHandler methods that handle fatal errors, nonfatal errors, and warnings as part of the ErrorHandler interface. As shown in the code extract in the previous section, the SAX parser delivers a SAXParseException to each of these methods, so generating an exception when an error occurs is as simple as throwing it back.
Note - It can be instructive to examine the error-handling methods defined in org.xml.sax.helpers.DefaultHandler. You will see that the error() and warning() methods do nothing, whereas fatalError() throws an exception. Of course, you could always override the fatalError() method to throw a different exception. But if your code does not throw an exception when a fatal error occurs, then the SAX parser will. The XML specification requires it.Handling Warnings
Warnings, too, are ignored by default. Warnings are informative and can only be generated in the presence of a DTD or schema. For example, if an element is defined twice in a DTD, a warning is generated. It is not illegal, and it does not cause problems, but it is something you might like to know about because it might not have been intentional. Validating an XML document against a DTD will be shown in the section .Running the SAX Parser Example without Validation
As stated at the beginning of this lesson, after you have downloaded and installed the sources of the JAXP API from the JAXP sources download area. the sample program and the associated files needed to run it are found in the following locations.
The different Java archive (JAR) files for the example are located in the directory install-dir/jaxp-1_4_2-release-date/lib .
The SAXLocalNameCount.java file is found in install-dir/jaxp-1_4_2-release-date/samples/sax .
The XML files that SAXLocalNameCount interacts with are found in install-dir/jaxp-1_4_2-release-date/samples/data .
The following steps explain how to run the SAX parser example without validation.To Run the SAXLocalNameCount Example without Validation
Choose one of the XML files in the data directory and run the SAXLocalNameCount program on it. Here, we have chosen to run the program on the file rich_iii.xml .
% java sax/SAXLocalNameCount data/rich_iii.xml
The XML file rich_iii.xml contains an XML version of William Shakespeare's play Richard III. When you run the SAXLocalNameCount on it, you should see the following output.
The SAXLocalNameCount program parses the XML file, and provides a count of the number of instances of each type of XML tag that it contains.
To check that the error handling is working, delete the closing tag from an entry in the XML file, for example the closing tag </PERSONA>. from line 30, shown below.30 <PERSONA>EDWARD, Prince of Wales, afterwards King Edward V.</PERSONA>
This time, you should see the following fatal error message.
% java sax/SAXLocalNameCount data/rich_iii.xml Exception in thread "main" org.xml.sax.SAXException: Fatal Error: URI=file:install-dir /JAXP_sources/jaxp-1_4_2-release-date /samples/data/rich_iii.xml Line=30: The element type "PERSONA" must be terminated by the matching end-tag "</PERSONA>".
As you can see, when the error was encountered, the parser generated a SAXParseException. a subclass of SAXException that identifies the file and the location where the error occurred.
