This layer gives switching & routing technologies, generating logical paths, termed as virtual circuits, for sending data from node to node. Routing and forwarding are the functions, as well as internetworking, addressing, error handling, packet sequencing and congestion control. The tutorials showcase the opinions and perspectives of experts that would cater your in-depth understanding of the topics which you would find of absolute importance when you design or analyze a system or structure of your own. An outsized computer network may seem just hassles of hardware; but actually it is also a multifaceted structure of rules, technically called as protocols which are executed and imposed by network operating systems. Before beginning our talk on Network Layers, it is a prerequisite to bri ef on the- seven layers Open Systems Interconnection model (OSI model) of Computer Networking. At the International Organization for Standardization, the communication systems were subdivided into smaller sections called layers. A layer provides services to its upper layer while getting services from the layer below.

The Perfect eProduct - Essay Example However, it is without question that with this drastic increase in available technology, the price of these devices have risen precipitously. Along with this price increase, so too as the consumption habits that the consumers display. Rather than changing a mobile device several times throughout the year, individuals are now encouraged, by simple force of economics, to retain their device longer, protect it, and seek to repair it in the off chance that it is somehow damaged. It is further estimated by experts that the industry responsible for the repair of mobile devices engenders an economy that is worth tens of millions of dollars annually. Whereas the repair of current mobile devices takes many shapes and forms, the most common repair that is engaged is repair of chipped, broken, or cracked glass screens. Whereas formerly mobile devices were put together with plastic LCD panels, the trend towards touch-screen devices has meant that more and more of these devices are now made with glass. As such, the product which will be promoted within this analysis for sale within the online market, will provide the consumer with an alternative to the exhorbitantly expensive screen replacements that can cost as much as 30% of the original phone’s cost. As such, the product which will herein be discussed and analyzed is a glass gel that has already been used in the automotive industry for decades which helps to seal and repair cracks, chips, or other imperfections on a glass surface. As such, the following section will engage the reader with a discussion and analysis of some of the key benefits that this particular product has to offer with regards to consumer utility and the ability of being sold online. The first of these is with regards the ultimate lightweight nature of the product itself. Comprising less than one fluid ounce, this particular product easily the ships; with little to no cost to the end consumer. Furthermore, it should also be understood that this particular product offers a tangential benefit of being a low-cost alternative the increasingly pricey cost of mobile phone screen repair; which was noted previously within this brief analysis (Wolf, 2012). As such, the gamble the individual consumer with regards to integrating person is your products are less than it would be if the product or service was closer in price to the alternative that face. A tertiary benefit is with regards to the fact that the existing supply of this glass gelling compound can easily be purchased in a litany of auto repair supply centers and repackaged at a significant markup (Moran, 2013). Fourthly, the high profit margin that could be denoted from this particular approach is clear and evident. Finally, it must be understood that there is ultimately no cost of research and development regards as the innovations are in place and the product provider is merely repackaging and reselling this product to the consumer for use in a different application that it was originally intended. Accordingly, the utility that can be gained from all of this, for the producer/seller, is that all of these facts help to directly translate to an increased level of money that can be saved on research and development, shipping costs, purchase of raw material in bulk, simplicity of product marketing, and a great many other

Examining The Network Simulations Of NS2 Information Technology Essay

Examining The Network Simulations Of NS2 Information Technology Essay NS2 is a Linux based tool to perform network simulations. NS2 is based on C++ and TCL programming Languages. TCL uses simple commands to define network configuration and C++ allows users to adjust protocol functionalities in detail and also to define new protocols. Our Project involves simulation of VoIP over two transport layer protocols UDP and SCTP. Installation of NS2: Installation of NS2 involves many steps. These Steps are: Checking for pre-requisites: Please make sure that you have installed the fedora 12 O.S with all packages and you are logged in as administrator. Downloading latest version of NS2: We first Downloaded NS2 v. 2.34 from: http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.34/ns-allinone-2.34.tar.gz/download Extracting the NS2 package: Extract the contents of .tar file in a directory and go into that directory. The following snapshot shows the extracted file against .tar file. Patching of SCTP module: Initially NS2 does not provide support to SCTP, so we have to download apply its patch before installation of NS2. The patch can be downloaded from http://pel.cis.udel.edu Now untar the patch in a directory and type the given command in terminal: patch -p0 Now we are ready to install NS2 with SCTP module. Installation of NS2 : We can either install NS2 by typing commands in the terminal. Or we can do this by simply double clicking the install file. The snapshot below shows the later. Now the installation has started. It would take some time to complete it. Configuring the installation path of NS2: The terminal will get get closed after installation of NS2. Now open terminal again and type: gedit ~/.bashrc to configure the path file Now edit this file as in the figure: Now save and close bash file and type following command in the terminal to tell your O.S about the path of NS2: source ~/.bashrc Confirming the installation of NS2: To confirm that NS2 is correctly installed, type ns in the terminal. The outlook of the terminal will be changed in this way: (Else it would print some filter of error in the terminal.) To revert to the normal mode type exit in the terminal. Running a simple code on NS2: NS2 executes .tcl file format. If you have followed all the previous steps, then you can execute a .tcl file by typing the following syntax in the terminal: ns [file name].tcl But make sure you are the directory where the .tcl file is present. e.g: Here we have a sample code script.tcl. In this code we are simulating a simple topology of two wired nodes. On typing ns script.tcl in the terminal, we get the following output: Handling the output trace file: On execution of .tcl code, two output files are generated. One is the .nam file with which we see the graphical simulation of our code. The other one is the .tr trace file, with which we can analyze the output of our simulation. The trace file looks like: It contains various parameters such as arrival time of packets, packet size transport agent etc. Using the trace file, we can get the graphical outputs to analyze the behavior of our simulation. To do this we need a graph drawing software such as xgraph or gnuplot. Here we are using gnuplot. But to draw a graph, we need to filter the trace file and get the coordinates out of which we can draw a graph. To filter a trace file, we write an awk script. Since we have to draw graphs for latency and throughput, therefore we will write one script for each type of graph. The awk script for latency is: #latency BEGIN { time1 = 0.0; time2 = 0.0; } { time2 = $2; if ($1==r) { printf(%f %fn, time1, time2) > latency; time1 += $2; } } END { print(Done); } And awk script for throughput is: #throughput BEGIN { node =1; time1 = 0.0; time2 = 0.0; num_packet=0; bytes_counter=0; } { time2 = $2; if (time2 time1 > 0.05) { thru = bytes_counter / (time2-time1); thru /= 1000000; printf(%f %fn, time2, thru) > throughput; time1 = $2; } if ($1==r) { bytes_counter += $6; num_packet++; } } END { print(Done); } Now type the following command in the terminal to filter the trace file: gawk file=[awk file name].awk [trace file name].tr The filtered file would be like this: Now weve to give a plot for which our graph is to be ploted. (i.e: weve to tell about the x and y coordinates) So we create a simple file in which we tell about these parameters. set title VoIP over UDP Latency! set grid set ylabel s set xlabel time plot latency w linespoints title voip throughput Now type gnuplot in the terminal to enter into gnuplot mode. Here type the command: load [x-y parameters file] (inner double quotes inclusive) And type exit to exit gnuplot Formation of VOIP Traffic over the Network: VoIP (Voice over IP) is simply the transmission of voice traffic over IP-based networks. The Internet Protocol (IP) was originally designed for data networking.   It is also referred to as IP  Telephony  or Internet Telephony. Simulating VOIP in NS2: VoIP is basically just UDP packets encapsulating RTP packets with the voice data inside, all you should need to do to simulate a VoIP stream is set the correct packet size and frequency that the packets are sent out and that would simulate a stream. In NS2 we will implement VOIP over UDP and SCTP protocols. We will implement VOIP using a simple two-node topology. For this we will do the following steps: create two .tcl files simulate VOIP traffic handle the trace files to draw graphs for latency and throughput for evaluation between the two protocols Simulation of VoIP over the network using UDP: Creating the tcl file:- First create a tcl file for Voip simulation over UDP protocol. Given below is the source code for our file voip_udp.tcl # start new simulation set ns [new Simulator] # setup tracing/nam set tr [open voip.tr w] set nf [open voip.nam w] $ns trace-all $tr $ns namtrace-all $nf # finish function, close all trace files and open up nam proc finish {} { global ns nf tr $ns flush-trace close $nf close $tr exec nam voip.nam exit 0 } ### creating nodes set node0 [$ns node] $node0 label Voice 1 $node0 color red set node1 [$ns node] $node1 label Voice 2 $node1 color blue # creating duplex-link $ns duplex-link $node0 $node1 256Kb 50ms DropTail $ns duplex-link-op $node0 $node1 orient right # setup colors $ns color 1 Yellow $ns color 2 Green ## 2-way VoIP connection #Create a UDP agent and attach it to node0 set udp0 [new Agent/UDP] $ns attach-agent $node0 $udp0 # set udp0 flowid to 1 $udp0 set fid_ 1 # Create a CBR traffic source and attach it to udp0 set cbr0 [new Application/Traffic/CBR] $cbr0 set packetSize_ 128 $cbr0 set interval_ 0.020 # set traffic class to 1 $cbr0 set class_ 1 $cbr0 attach-agent $udp0 # Create a Null sink to receive UDP set sinknode1 [new Agent/LossMonitor] $ns attach-agent $node1 $sinknode1 # Connect the UDP traffic source to Null sink $ns connect $udp0 $sinknode1 set udp1 [new Agent/UDP] $ns attach-agent $node1 $udp1 $udp1 set fid_ 2 set cbr1 [new Application/Traffic/CBR] $cbr1 set packetSize_ 128 $cbr1 set interval_ 0.020 $cbr1 set class_ 2 $cbr1 attach-agent $udp1 set sinknode0 [new Agent/LossMonitor] $ns attach-agent $node0 $sinknode0 $ns connect $udp1 $sinknode0 # end of voice simulation setup # start up traffic $ns at 0.1 $cbr0 start $ns at 0.1 $cbr1 start $ns at 10.0 $cbr0 stop $ns at 10.0 $cbr1 stop $ns at 10.5 finish # run the simulation $ns run Simulate VOIP traffic: Now type the following command in the terminal to view simulation of VOIP over UDP: ns voip_udp.tcl The output is: Performance of SCTP: Now we draw the graphs with gnuplot using above mentioned steps. The performance is evaluated on the basis of latency, throughput and capacity. The capacity can be evaluated with the help of latency and throughput. Latency: Throughput: Simulation of VoIP over the network using SCTP: Creating the tcl file:- First create a tcl file for Voip simulation over UDP protocol. Given below is the source code for our file voip_sctp.tcl # start new simulation set ns [new Simulator] # setup tracing/nam set tr [open voip.tr w] set nf [open voip.nam w] $ns trace-all $tr $ns namtrace-all $nf # finish function, close all trace files and open up nam proc finish {} { global ns nf tr $ns flush-trace close $nf close $tr exec nam voip.nam exit 0 } ### creating nodes set n0 [$ns node] $n0 label Voice 1 $n0 color red set n1 [$ns node] $n1 label Voice 2 $n1 color blue # creating duplex-link $ns duplex-link $n0 $n1 256Kb 50ms DropTail $ns duplex-link-op $n0 $n1 orient right # setup colors $ns color 1 Yellow $ns color 2 Green ## 2-way VoIP connection #Create a UDP agent and attach it to n0 set sctp0 [new Agent/SCTP] $ns attach-agent $n0 $sctp0 $sctp0 set fid_ 1 set cbr0 [new Application/Traffic/CBR] $cbr0 set packetSize_ 128 $cbr0 set interval_ 0.020 # set traffic class to 1 $cbr0 set class_ 1 $cbr0 attach-agent $sctp0 # Create a Null sink to receive Data set sinknode1 [new Agent/LossMonitor] $ns attach-agent $n1 $sinknode1 set sctp1 [new Agent/SCTP] $ns attach-agent $n1 $sctp1 $sctp1 set fid_ 2 set cbr1 [new Application/Traffic/CBR] $cbr1 set packetSize_ 128 $cbr1 set interval_ 0.020 $cbr1 set class_ 2 $cbr1 attach-agent $sctp1 set sinknode0 [new Agent/LossMonitor] $ns attach-agent $n0 $sinknode0 $ns connect $sctp0 $sctp1 $ns at 0.1 $cbr0 start $ns at 0.1 $cbr1 start # stop up traffic $ns at 10.0 $cbr0 stop $ns at 10.0 $cbr1 stop # finish simulation $ns at 10.5 finish # run the simulation $ns run Simulate VOIP traffic: Now type the following command in the terminal to view simulation of VOIP over UDP: ns voip_sctp.tcl The output is: Performance of SCTP: Now we draw the graphs with gnuplot using above mentioned steps. The performance is evaluated on the basis of latency, throughput and capacity. The capacity can be evaluated with the help of latency and throughput. Latency: Throughput: Difference between SCTP and UDP: SCTP: SCTP Stands for Stream Control Transmission Protocol. It is a Transport Layer protocol. It is a connection-oriented protocol similar to TCP, but provides facilities such as multi-streaming and multi-homing for better performance and redundancy. It is used in Unix-like operating systems. UDP: UDP stands for User Datagram Protocol. It is a minimal message-oriented transport layer protocol. It enables two hosts to connect and send short messages to one another. Unlike Transmission Control Protocol (TCP), it does not guarantee that data is received or that it is received in the order in which it was sent. Comparison between SCTP and UDP: Message Orientation: In SCTP, message boundaries are preserved. If an application sends a 100-byte message, the peer application will receive all 100 bytes in a single read: no more, no less. UDP provides a message-oriented service, but without SCTPs reliability. Un-Ordered Service: In addition to ordered message service (and parallel ordered service discussed above), SCTP offers the reliable delivery of messages with no order constraints. UDP provides unordered service, but again without SCTPs reliability. Unordered reliable delivery will be useful for many applications, in particular disk over LAN services (iSCSI, RDMA, etc.) where the application already provides ordering. Stronger checksum: SCTP uses a 32-bit end-to-end checksum proven to be mathematically stronger than the 16-bit ones-complement sum used by UDP. SCTPs better checksum provides stronger verification that a message passes end-to-end without bit errors going undetected. These were some of the differences between SCTP and UDP. A tabulated contrast between the two protocols is given below: Services/Features SCTP UDP Connection-oriented yes no Full duplex yes yes Reliable data transfer yes no Partial-reliable data transfer optional no Ordered data delivery yes no Unordered data delivery yes yes Flow control yes no Congestion control yes no ECN capable yes no Selective ACKs yes no Preservation of message boundaries yes yes Path MTU discovery yes no Application PDU fragmentation yes no Application PDU bundling yes no Multistreaming yes no Multihoming yes no Protection against SYN flooding attacks yes n/a Allows half-closed connections no n/a Reachability check yes no Psuedo-header for checksum no (uses vtags) yes Time wait state for vtags n/a SCTP vs. UDP Latency: From the graphs of latency we conclude that latency is slightly higher in UDP. In real practice, latency in UDP is much higher than in SCTP. Practically, the latency in UDP is about 15% more than SCTP. Throughput: From the graphs of throughput we see that UDP shows a constant but less throughput while SCTP shows continuous fluctuations in its graph. But overall SCTP has a higher throughput than UDP. In real practice, throughput in SCTP is about 15% more than in UDP. Capacity: By observing the graphs of throughput, we conclude the SCTP can support more capacity than UDP. UDP will loose its performance at higher data rates. Conclusion: From the above statistics, we conclude that SCTP is better than UDP in terms of latency, throughput and capacity. Therefore there is no doubt in the fact that that SCTP is going to be the future of VOIP and many other network technologies. But since this technology is under the process of evolution so it may take some time for it to replace the older technologies like UDP and TCP etc. Refrences: http://yonghoon.livejournal.com/4799.html http://www.isoc.org/briefings/017/index.shtml http://www.google.com/dictionary?source=dict-chrome-exsl=entl=enq=sctp http://www.google.com/dictionary?langpair=en|enq=udphl=enaq=f http://mailman.isi.edu/pipermail/ns-users/2006-August/056723.html http://books.google.com.pk/books?id=bF3L7g1u_mQCpg=PA189lpg=PA189dq=udp+vs+sctp+latency+throughputsource=blots=zdb5JeCsMfsig=PPt8c4nvtcrIJcXr5eKBIe_GbkQhl=enei=XhIgTYCeLs-z8QO8_KS8BQsa=Xoi=book_resultct=resultresnum=2ved=0CB4Q6AEwAQ#v=onepageqf=true

Mortuary Practices and Afterlife of the Choctaw Essays -- Sociology, T

The Choctaws thrived in the fertile sandy, red-clay soil, rolling hills, and dense forests, located in the Central Hills of the east-central region of Mississippi. The estimated population after early European contact was between 15,000 and 20,000 and was the second largest group of Native Americans in the Southeast (Blitz 1988:127). The Choctaws in the Southeast were a matrilineal society. Traditionally, women preformed tasks related to domestic life. Among these responsibilities were creating pottery and utensils, food preparation, and planting and harvesting crops. The majority of their diet consisted of agricultural products such as corn, pumpkins, squash, and beans. Women would also accompany men on hunting excursions in order to provide food preparation. After the hunt, women were responsible for transporting the slain animal back to the village for processing of skins, bone, and meat (Carson 1995:495-6). The greatest responsibilities of the Choctaw men were hunting and warfare. During the fall and winter months, their primary food source was deer. Their accomplishments on hunting adventures directly reflected upon their social status and importance within the tribe (Carson 1995:197). Although the Choctaw shared much of their culture with many of the other tribes in the Southeast, â€Å"in the disposition of their dead, the ancient Choctaws practiced a strange method different from any other Nation of people, perhaps, that ever existed† (Swanton1931:176). When a Choctaw tribal member became terminally ill, it was common practice for the medicine man to inform the family of impending death (Swanton 1931:170). The women cleansed the body, applied paint, daubed the face, and dressed him in his finest clothes. He was the... ...ld winds always blew. Every spirit encountered was an enemy with no safe place to take refuge. Food was scarce, due to unfertile soil, lack of game, and hunger was constant. The bad hunting grounds are perpetually lonely, with only the joyous sounds from the other side of the mountains. The doomed spirits constantly struggled to climb the treacherous mountains, but to no avail. They were eternally destined to an afterlife of desolation (Campbell 1959:149-52). The Choctaws possessed unique ceremonies in regards to their deceased as well as a vivid explanation into their afterlife. Through many accounts, the knowledge and customs of the Southeast tribe of the Choctaw will not be forgotten. Although these customs may not be practiced, the extensive documentation gives an extraordinary glimpse into the lives of the natives of the southeast United States.

School administrators Essay

Education plays an important role in the life of almost all individual because this is the means by which they can gain knowledge and reach their full potential. In line with this, educational institutions give due importance to their curriculum in order to make sure that they are covering all the subjects and lessons that will help their students to develop their skills and talents. In line with this, almost all educational institutions include the arts as an important part of their curriculum because of the essential skills, talents, and values that students can develop from this area of education. Dance class is one of the major parts of the arts area of education that allow students to learn body coordination, music appreciation, and also a better understanding of various cultures through the different dance genres that are being taught. However, there are problems within educational institutions that resulted for most school administrators to cut-back or even completely eliminate dance classes and other art programs. Public schools usually have the most problems when it comes to maintaining dance classes because of the lack of school budget, facilities, and other needed materials to maintain dance classes. In relation to this, public school administrators also have to deal with the limited number of educators or teachers that will instruct students about the different genres of dance. Due to the challenges that public schools have to deal with, there is a continuous debate on whether dance classes should still be included in the educational curriculum. The on-going debate about the importance and need of dance classes in education is an important topic of study because it deals with the holistic learning and development of students. A comprehensive study should be made in order to identify whether there is really a need for dance classes to be included in the curriculum of most schools or having dance classes only give unnecessary cost and further contribute to the problems of public schools. In line with this, the research study that will be conducted gives primary focus on identifying whether there is really a need for dance class in education or not. In doing so, the corresponding pros and cons about dance class in education will be given due attention and importance. Identifying the positive and negative implications about dance class in education will substantially help the stakeholders in the issue. Stakeholders will be able to properly assess whether there is really a need for dance classes to be included in the educational curriculum or not. Studying the need for dance class in education is essential because the holistic development and well-being of students are at stake in this issue. Statement of the Problem The study aims to assess on whether there is a need for dance class in education, particularly in the secondary level of education. Specifically the study intends to: †¢ Describe the commonly used educational curriculum in the secondary academic level with emphasis on arts programs, specifically dance classes. †¢ Identify the positive effects of dance classes in education, especially when it comes to the development of students and their performance at school. †¢ Identify the negative effects of dance classes in education, especially when it comes to the development of students and their performance at school. †¢ Assess the effects of dance class to students and the need on whether to include it in the educational curriculum. Justifications for the Chosen References The articles that are included in the literature review section of this paper are chosen by the researcher because these articles exemplify the corresponding implications of having dance classes in educational institutions. Most the articles that were discussed in the literature review of the paper are studies that are previously made by different researchers about dance classes in education. In line with this, there are also case studies that are part of the literature review of the study that talks about the actual situation and experiences of students in specific schools about dance classes as part of their educational curriculum. Moreover, the researchers and writers that are responsible in creating the articles that are part of the literature review of the study are respectable individuals that actually have the necessary knowledge and expertise about dance and education. Relevance of the Articles to the Research Topic The article which had been chosen for this research are all important aspects pointed out towards the connection of dance with academic and personal life of each student. The chosen articles are a representation of different sides of research which discusses the importance of dance in the life of the youth. The articles contain the positive perspectives with dance and the values which are gained throughout such activity. The values that are highlighted are not only applicable for academics but also within the personal life of each student. More so, the articles will largely support the positive effects of dancing towards the youth. On the other hand, the articles utilized were providing various kinds of perspectives from different authors which are already experienced regarding such matters. Furthermore, the discussions of the authors are true to what is seen within schools. Most of the articles present are explaining the importance of dance in the lives of each student that will lead to their growth. More so, the articles are significant to the development of the literature review as well as the other parts of the paper such that of the analysis and findings and conclusion. The articles have specific concepts and theoretical perspectives that are very efficient in attaining the proper analysis. Also, the authors that are chosen for the whole paper are well versed in the topic they have written. In the light of this, the articles shall create a path towards a clear understanding regarding the concept of dance in relation to academic perspective. Therefore, there is a need to utilize different types of materials which had created earlier studies regarding dance schools in the secondary level. Through the use of different articles, this would shed light to the aim of proving that dance lessons are needed by students in the secondary level. Literature Review Article Title: Dance Education Research: What Train Are We On? Karen Kohn Bradley, a dance educator, conducted a study regarding the role of dance classes in the educational reforms of public schools in the United States. Bradley admitted that as a dance instructor she is aware that learning through movement like dance is a powerful agent that substantially helps in the enhancement of the cognitive skills of students. In the same manner, she also pointed out that dance classes teach students the valuable lessons, especially in terms of discipline. The two aforementioned approaches of dance education often create tension, which is not realized by educators in public schools that teaches dance classes. However, the present condition of public schools requires accountability and educational reform in order to properly address the root causes of current problems. In line with this, the relevance of dance in American public schools during the time of educational reform is given more emphasis (Bradley, 2001). Bradley pointed out in her study that dance programs and classes are among the most under-represented and marginalized, and misunderstood field of education. The important role of dance classes in public schools are often taken for granted, which is why there is a big possibility that it would not achieve due recognition in the reforms that are happening in American public schools. Bradley proposed that dance educators and other stakeholders in the field of dance education should start giving more value to themselves but further mastering in their craft. Furthermore she also pointed out that dance educators and stakeholders should not give up their fight in the inclusion of dance classes in public schools, especially since they are very much aware of the benefits that it can provide to their students (Bradley, 2001). Article Title: Nurturing Excellence through the Arts In the written work of Vanessa Camilleri and Anthony D. Jackson with the title â€Å"Nurturing Excellence through the Arts† stated that it is important that art classes must be taken by different students for it is will provide a very positive effect for the students. In ATA or the Arts and Technology Academy, the students are required to have extracurricular activities in three times a week in the whole school year. Moreover, there is direct participation of various professors and parents in developing a certain program that would enhance the ability of the students in the arts. The authors were able to mention that the arts program is not only limited to dancing but to the wider variety of performing arts. The school was able to create a program where in art shall be a source of education for the students. In the light of this, it is presented that the school wanted to integrate learning from a philosophical perspective of arts. More so, it is dancing which will bring a higher development for students not only in terms of academic level but also for their personal development. In the philosophy of the school, the lessons bring the students bring artistic content and develop the emotional and social skills of children. It is mentioned that in reality, it is the computing and interpersonal skills that must be developed in order to adapt in the modern world. Therefore through the activities in the performing arts, students shall be much more able to comply to the fast paced world with fewer complications. Definitely, the techniques of teaching the children utilized in ATA is highly focused on the arts as its association the development and nourishment of students in their future lives (Camelleri & Jackson, 2005). Article Title: Performance and Motivation in Dance Education In the written work of Elizabeth Lazaraoff, it is evident that there is the need to incorporate dancing as one of the main subjects in public schools for it is one of the most effective motivational practices available in teaching. For most students get bored in schools due to their uninterested attitudes, it is dancing or the whole perspective of performing arts must be associated with the development of students and the curriculum in public schools. For most schools are focused in science and math, a new concept that is much relatable for children in the elementary level shall help motivate students in being active in school. Furthermore, the author suggests that the performing arts must be associated not only in the curriculum but also in the teaching techniques of teachers. Article Title: Gliding Glissade Not Grand Jete Elementary Classroom Teachers Teaching Dance This article presents that there is a need to create a program of dancing in the elementary level. Such levels are very fun loving and playful hence, they are needed to be stimulated through performing arts in order for them to be much motivated. However, the article created by Anne Dunkin states that the elementary level is very good in absorbing and appreciating such type of concepts. On the other hand, other levels such as the secondary and university level are less appreciative in such kind of teaching. More so, the US Department of Education pointed in their 2002 report that most secondary and elementary schools are not practicing art education. There are only one fifth of schools in the United States offer the instructions in dancing. Hence, not all students have the opportunity dancing and performing arts as a whole. Therefore, Dunkin wanted to attain a level of awareness that there is a need to incorporate dancing in the curriculum of each school in the United States. Although the goals might not be possible in the next five years of the thought of such association of dance to schools are also not impossible. The author suggests that there must be a full regarding with such type of issue. There must be a high association that would pursue the interests of students in their artistic side. With such type of organization, the possibility of attaining an artistic curriculum shall be created (Dunkin, 2004). Article Title: Dance Education in Elementary Schools Based on the research study regarding the status of K-12 dance education, two levels of implications have been observable about dance education: the first one of the practical effect while the other one involves the clarification of visions. The practical implication emphasized the need to include new requirements about dance classes with corresponding guidance and resources in order for students to effectively learn in their dance lessons. However, there is a huge gap between the requirements and the reality because extensive teacher training and the need for provision materials should be given attention, since these are the main problems that affect dance classes and programs. Moreover, teachers should not be merely regarded as technical support because it is pivotal that they are included in the decision-making process when it comes to educating students (Bresler, 1992). Article Title: K-12 Dance Education: Four Model Programs The article written by Bresler discussed dance education in elementary schools by means of narrating and assessing a particular research study about the status of dance education in elementary schools. The status of dance education was studied by means using four perspectives, namely: â€Å"musician Liora Bresler, an outsider, looks at dance programs in Illinois elementary schools† (Knowles et al. , 1992, n. p. ). In line with this, other reputable personalities also participated in the study of Bresler, such as: Susan Stinson, who represented the perspective of high school students about the value of dance; Patricia Knowles and Rona Sande presented a model dance programs in four different parts of the United States; and Peggy Schwartz is the one responsible in the creation, development and even demise of the dance certification for educators in the state of Massachusetts. The efforts made by the different important people in the study contributed in gathering the necessary data about the national trends in teacher education, requirements for certification, and the application of programs (Knowles et al. , 1992).

Article Title: Revitalizing Pennsylvania through Creativity: Dance Education Giguere, a Pennsylvanian herself, wrote an article that talks about the way by which their place was able to address difficulties through the help of dance education. The author pointed out the bleak future of Pennsylvania due to the economic hardships that it is experiencing. In addition, Pennsylvania also has to deal with other problems such as: slow population growth, aging work force, and the increasing presence of suburban slumps. The aforementioned untoward situation of Pennsylvania is greatly contributing to the â€Å"brain drain† of its highly-educated and competent workers. Giguere was able to found out in her research that the reasons for the flight of most young professionals are due to the lack of arts and culture in local Pennsylvania communities. In line with this, Giguere emphasized that Pennsylvania can actually make its situation better by means of improving its arts and culture by establishing and improving dance classes. The author strongly believes that the strength of Pennsylvania is not found in technology but rather in enriching its arts and culture. (Giguere, 2005).

Rich and Unhappy or Poor and Happy

* Choosing a career that pays well, but makes a person unhappy, and choosing a career that   makes a person   happy,but does not pay well. What is the purpose of life? What is the one thing that truly matters in order to experience a meaningful, gratifying existence? Some people might say that love and happiness are all one needs in order to live a fulfilling life, where no amount of materialistic wealth will amount to the same level of contentment as a life where one’s career is something that one strongly believes in and has passion for.Others, however, might argue that the only path to an enjoyable life is when one is able to live luxuriously. To have the finest, rarest, most expensive items or clothing is to have value and importance in society, which in turn, makes life worth living. In order to reach this stage, necessary steps need to be taken even if it causes unhappiness doing so.Choosing a career that ensures a generous paycheck will guarantee a life filled with materialistic commodities, but it doesn’t guarantee the benefits of a career that entices them, such as the drive or desire to work and the gratification one feels that might affect their emotional well being for the better. Yet, Choosing a career that sparks interest and passion guarantees a feeling of fulfillment but may not guarantee a substantial enough pay to enjoy some of society’s luxuries, such as the ability to travel or not having to worry about putting food on the table which otherwise might lead to stress that is harmful to one’s health.In a perfect world, everyone would be able to choose a career that houses both aspects, but alas, that is not the way the world works. Should one choose a career that pays well, but makes one unhappy? Or should one choose a career that makes one happy, but barely pays the rent. A life filled with the luxuries that our society provides can be seen by many to be a much-desired way to live. For them, the end result overc omes the means to get there, such as a stressful, unrewarding career who’s only redeeming aspect is a substantial paycheck.The ability to purchase the materialistic objects of ones desires, such as a fancy car, or a big house, is enough for some people to put themselves through school in a programme that doesn’t stimulate them emotionally, or intellectually. Nevertheless, with the disposable income, one would be able to take part in activities outside of work that is enjoyable and stimulating, like traveling or going to various cultural events that are out of reach for those with lower incomes.However, while one may be enjoying life outside of work, the harsh reality is that one spends the majority of the week at ones job, so in reality, a huge portion of one’s life is spent in apathy and indifference if the work doesn’t invoke any sort of enjoyment. As this continues over the years, depression is likely to follow due to the constant dread and lethargy th at goes along with the job, and the realization that it will be like that day in and day out for years to come.For those who choose this way of life, happiness equates to the number of possessions they gained with their hard earned money, regardless of the mundane work they had to go through in order to achieve it, unless of course, they realize they made a huge mistake choosing money over their actual dreams and aspirations when its already too late. Other people have a completely different view of life as the ones who value money in high regard.These people see the benefits of a life filled with things that give them satisfaction, with the choice of career being a huge component of it. When one decides to spend the rest of ones life doing something that one is passionate and excited about, the wage it garners wouldn’t be high on one’s list of concerns, especially if it means that waking up every morning wouldn’t be such a dreaded daily event. The mere thought of spending another day doing something one enjoys is enough to keep one motivated throughout the longevity of their career.There are a few instances however, that may cause certain hesitation. For example, a young aspiring artist might be satisfied with a one-bedroom that doubles as their studio while eating ramen noodles for breakfast, lunch and dinner for now, but what if down the road they decide they want to settle down and have a family before they are able to make a profit from their art, which might not never even happen in the first place? The pressure of this realization and the constant worry of having to make ends meet could be detrimental down the line.Soon, the joys that the job brings could be overshadowed by the stress produced by this situation. Fortunately, most people that choose to go down this path are able to make ends meet and are content with living in the simplest terms as long as their lives revolve around the career of their liking. The decision of choosin g which career path to take is probably one the most important, tear-inducing decisions a person has to make in their lifetime. It will dictate the way their life will go from that day forward nd the means on which they must live by. Whether it is a career that will bestow significant financial gain, or a career that will bestow significant personal gain, the decision rests on the personal opinions of the individual’s definition of a happy life. Even though this decision is entirely subjective, there is a stat that is worth mentioning; over a third of an average person’s life is spent working.
