The French word croire is an irregular verb that means to believe, and it may require the subjunctive, depending on whether it is used affirmatively, negatively or interrogatively. An affirmative sentence calls for the indicative, rather than the subjunctive. Youll use the subjunctive when ââ¬â¹croire is used to express doubt or uncertainty. Examples Je crois quil a raison.I think hes right. Je ne crois pas quil ait raison.I dont think hes right. Crois-tu quil ait raison ?Do you think hes right?

In The First Theory,Realism, The International System Is
In the first theory, Realism, the international system is defined by anarchy and the lack of a central authority, meaning that states are independent from each other and no structure or system can establish a forced relation among them. In this type of system, power is the main objective that each state plans to accomplish because only by achieving this power they can protect themselves and survive. According to this theory, there are different powers that a state plans to achieve for example the military power, the economic power or the diplomatic power. States seek to achieve the instruments of ââ¬Å"hardâ⬠and ââ¬Å"softâ⬠power, to gain influence over other states and to accomplish this goal may be necessary to engage in war, conflicts orâ⬠¦show more contentâ⬠¦The Realism theory explain that even if all the countries appear to have different objectives according to particular circumstances, in reality they have common intentions, which are focused on re-bui lding the logic of policy makers. And the last assumption sees a country as a ââ¬Å"unitary actorâ⬠. The nature of the international system defines the main problems that a country can face (Holsti, 1985) . Realism was a dominant model of explaining the concept of international relations during the past six decades and was considered to be a framework in order to analyses and understand better the First World War, The Second World war, and the Cold War. But, Classical Realism is described as a pessimistic theory of understanding the human nature, when is distinguished that egoism and self-interested attitude are base of the phenomenon known as ââ¬Å"homopoliticusâ⬠. According to Classical Realism, the question of why exists conflict and war in the world is founded on human nature characteristics. In order to eliminate this problem, later was developed a new theory, the Modern Realist theory, which pointed out that the structure of the international system can be used as an instrument to explain and understand more the state behavior. The Modern Realists realized that words like ââ¬Å"powerâ⬠, ââ¬Å"national interestsâ⬠or ââ¬Å"balance of powerâ⬠, are contradicto ry concepts. According to Classical Realism theory, power is an important element, but the relation among power balance and political output,Show MoreRelatedThe Theory Of International Relations1402 Words à |à 6 PagesThere are different theory of how international relations should operate, such as Liberalism, Realism, Marxism, Constructivism, the English school often called the international society, Feminism, Green theory, Hegemonic stability theory, Postmodernism and Post colonialism.

Billy The Kid Essay Example For Students
Billy The Kid Essay Billy the KidBilly the Kid is one of the most famous outlaws in American history.He has been a widely told figure in American history as well as folklore.The have made movies from his history and have also wrote many books on him.Most of Billy the Kids life remains a heated controversy throughout America. Billy the Kid was born in New York City on November 23, 1859 to William and Kathleen McCarty Bonney and given the name William H. Bonney (There are other stories of his birth but this one is the most reliable).The first recorded killing committed by Billy the Kid was on August 17, 1877.This is also where he got his nickname Kid.The story has it that he got in a fight with a blacksmith in a saloon where the blacksmith slapped him and threw his to the floor.Knowing that he was no match for the much bigger and older blacksmith he drew his gun and shot the blacksmith who died the next day.He was arrested but the escaped and began running from the law, something he did all of his life. Billy the Kid eventually moved to Lincoln County, New Mexico were he began working for J.H. Tunstall.Tunstall was a rich farmland owner who had an ongoing feud with L.G. Murphy and J.J. Dolan over farmland and grazing rights.Billy the Kid looked at Tunstall as a father and would do anything for him.But on February 18, 1878, Tunstall was gunned down by a group of deputies who were under the authority of Sheriff William Brady who was a major Murphy and Dolan supporter.Billy the Kid swore revenge and said he would not rest until the Murphy and Dolan group was dead.Billy had ended up killing most of the group but was still looking for Sheriff Brady.On April 1, 1878 Billy got his wish.Billy and a group of five friends positioned themselves behind an adobe wall and waited for Brady and his posse to come into town.When they finally did Billy and his band of outlaws opened fire from their ambush and killed Brady and his posse.Even though Billy used great strategy to gain the upper hand on Br ady he was regarded as a coward for the ambush and lost the support of the people who had supported him. While the Lincoln County War went on between Billys gang and the new sheriff George Peppin, Lew Wallace the new governor had charged Billy with murder.When Billy heard of this he told Wallace that he would turn states evidence on three killers if he received a full pardon.Wallace agreed and met with Billy on March 17, 1879.When they finally met Wallace was shocked to see a slender boy with only a faint stubble of beard, who was the most feared gunman in the West.Even though he agreed to testify he didnt want to surrender so Wallace granted a fake arrest.Billy testified and with that it brought great fame.He reveled in this fame and couldnt get enough of it.After the trial Billy agreed to be put on a mock trial for murder but Wallace guaranteed his release.Even though he was assured a pardon Billy decided to escape.That is when Wallace put a $500 price on his head and when one of his good friends Pat Garrett became a sheriff and was sent to look for him. Billy the Kids death is probably the greatest debated aspect of his life.On July 14, 1881 while Billy was visiting a Mexican woman at the Maxwell ranch Pat Garrett found him in the large ranch house.In Garretts report he stated that Billy came into the bedroom armed with a pistol and a knife expressly to kill me if he could.I had no alternative but to kill him or suffer death at his hands.It is reported that Billy had been shot in the back while others report that Garrett had shot him right in the heart.Either way the brief career of this outlaw ended in a very short time.

For illustration, costs can find the merchandising monetary value of a merchandise. If the cost of doing that specific merchandise is well high, so it is natural for the direction to raise the monetary value of that merchandise in order to do a satisfied net income. If a concern requires the purchase of a new machinery to increase it s end product but the short-run financess are used for these purchases, this may do working capital jobs. In consequence, the costs of buying new machinery determine the budgeting control of a house. Economists frequently assess the cost of something in footings of the foregone option, the chance cost. For illustration, the cost of buying new machinery with short-run financess will ensue in the house being able to increase its end product, nevertheless it will cut down its liqu idness place. Efficaciously, costs non merely find the gross and net income of the concern, it provides information for directors in direction accounting with assistance to decision-making ( Marcouse, 2003 ) . In dividing each cost harmonizing to how it behaves, the ability to foretell how costs will alter or respond to the alterations in the degree of concern activity or volume can be examined. The categorization of costs will be explained as follows: Variable costs Fixed costs Semi-fixed costs Semi-variable costs Variable costs Variable costs are those that move straight relative to activity ( one unit consequences in RM 1 of variable cost, two units result in RM 2 of variable cost ) ( Dyson, 2001, p.375 ) . They represent payments made for the usage of inputs such as labor, fuel and natural stuffs and if our maker doubled end product so these costs would lift significantly and proportionally. There would be excess costs for the extra natural stuffs and fuel which would be required. Besides, more labors would most probably be required, incurring excess costs in the signifier of rewards. Fixed costs Fixed costs are costs which do non change with altering degrees of activity, for illustration, mill rent, insurance and rates ( Glautier and Underdown, 2001, p.402 ) this means that, when the sale end product rises, fixed costs remain the same. However, the cost per unit of a merchandise reduces as sale end product rises. This is because the cost can be more spread over. An illustration is our new Surrey Quays Factory rent imposed this twelvemonth no affair how much an activity degree additions, the cost of the rent will stay the same regardless. But, suppose the rent was RM 250 per hebdomad fixed and sale end product within that hebdomad increased from 200 units to 500 units ; its original cost per unit was RM 1.25 but with its addition end product of 500 units, cost per unit falls to RM 0.50. .u70465522939f8b573137985c8a2118ba , .u70465522939f8b573137985c8a2118ba .postImageUrl , .u70465522939f8b573137985c8a2118ba .centered-text-area { min-height: 80px; position: relative; } .u70465522939f8b573137985c8a2118ba , .u70465522939f8b573137985c8a2118ba:hover , .u70465522939f8b573137985c8a2118ba:visited , .u70465522939f8b573137985c8a2118ba:active { border:0!important; } .u70465522939f8b573137985c8a2118ba .clearfix:after { content: ""; display: table; clear: both; } .u70465522939f8b573137985c8a2118ba { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u70465522939f8b573137985c8a2118ba:active , .u70465522939f8b573137985c8a2118ba:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u70465522939f8b573137985c8a2118ba .centered-text-area { width: 100%; position: relative ; } .u70465522939f8b573137985c8a2118ba .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u70465522939f8b573137985c8a2118ba .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u70465522939f8b573137985c8a2118ba .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u70465522939f8b573137985c8a2118ba:hover .ctaButton { background-color: #34495E!important; } .u70465522939f8b573137985c8a2118ba .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u70465522939f8b573137985c8a2118ba .u70465522939f8b573137985c8a2118ba-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u70465522939f8b573137985c8a2118ba:after { content: ""; display: block; clear: both; } READ: Animal cruelty EssayFixed costs, by definition, stay unchanged over declared scopes in the volume of production ( Wood and Sangster, 2005, p55 ) but if production additions above a certain figure, so what may be considered as a fixed cost of leasing the mill could alter. The concern might necessitate to lease extra premises to fit demand as it increases. It is hence required for the stated scopes to be moderately concise, so that what are considered fixed costs, are costs which are fixed in the short term . ( Wood and Sangster, 2005 ) The ground for this is because a alteration would non usually go on in the short term . From the illustration above, if the demand of ex tra premises were required due to the addition in gross revenues end product, it would still take a piece to lease and put up these new premises before production can get down. Semi-fixed costs Semi-fixed costs are costs composed of a mixture of fixed and variable constituents basically it is a fixed cost that increases in stairss. In the earlier illustration of the rent as a fixed cost, it can be understood that this behavior can be classified as a semi-fixed cost, since the addition of end product outside the scope would ensue in the addition in rent of extra infinite. Semi-variable costs A semi-variable cost is a cost incorporating both fixed and variable constituents and which is therefore partially affected by a alteration in the degree of activity, but non in direct proportion. ( Davies, 2002, p.284 ) Examples of such costs include telephone measure, Internet use and electricity measures.

Observation Review Essay Example | Topics and Well Written Essays - 1500 words
Observation Review - Essay Example The decision made by Christopher Bale, who was the chief site engineer at a construction firm, where I have worked can be cited as exemplifying the concept of bounded rationality. The work contains my personal observation and experience regarding the decision making process of the organization. In the case, Mr. Bale had decided to increase the working hours of the construction workers to two hours in the morning shift. The normal routine shift usually started from 8 a.m. in the morning and continued till 5pm in the evening. The company had entered into a deal according to which it had to construct a multistoried building. Initially the contract was to be completed in a two years time. But later the contract had to be renewed and its duration was lessened by six months. This put pressure on the executives to complete the work fast. Therefore, the chief site engineer, Mr. Bale, decided to increase the working hours and, correspondingly, compensation of the employees. The decision was n ot favored by the employees as they felt their opinion was not considered. Secondly, a few of the employees who were more than 50 year old felt that it would affect their health if they were made to work beyond the routine hours. Assessment of the Example Using Simonââ¬â¢s Bounded Rationality Theory In the example mentioned above, Bale thought it would be feasible for the company to increase the working hours of the site workers so as to complete the work on time. This is a clear example of bounded rationality as the site engineer had taken the decision after examining the available choices only. He did not have knowledge about the resentment, if any, that would be prevailing among the workers due to the increase in the number of work hours. He was also unaware of the health conditions of the senior employees. The decision taken by Bale can be considered to be an example of decision making based on normative affective factors (Etzioni, 1988). It is more of a normative model becau se Bale made the decision assuming he had all the necessary information needed to make the choice. Thus it was more of a descriptive form of decision making instead of a prescriptive form (Holloway, 2003). This descriptive form of making decisions was termed as bounded rationality by Simon. Simon theorized that human beings often settle for solutions that are mostly satisfying in nature, which means that such solutions, though they are sufficient to cope with the situation, are not the best solutions (Turban, 2008). There are many factors that can affect a decision. These can be psychological, sociological, political, risk avoidance motives, etc. These can influence the choice of the decision made considerably. In the context of the case, it can be understood that the company executives were put under tremendous strain to complete the construction work six months ahead of the contracted time initially stipulated. They had to come up with a solution so as to complete the work fast as their commitment and their reputation were at stake. In such a situation it is possible that when the decisions were made, not all the crucial factors were considered. Two such factors were the workersââ¬â¢ opinions on the decision to increase work hours and the health condition of some workers. The chief site engineer had suggested the idea to

Managerial Control Systems (Take home exam) Essay
Managerial Control Systems (Take home exam) - Essay Example to significantly reduce these emissions (p. 81). The choice of approach depends upon the nature of the business, its motivations and objectives, and the environment it functions in. As a result, there is no one best way by which organizations may achieve their carbon emission targets. The advantages to the firm in the second to the fourth approaches are self-evident, in that energy savings which reduce emissions reduce costs, and the positive publicity enhances the firmââ¬â¢s standing among its consumers. The first approach has to do with the trading of emissions certificates, wherein businesses whose operations require higher emissions purchase pollution permits from other firms who do not need theirs. In this manner, firms who reduce their emission levels have no need for their emission certificates, and may sell them to other firms and therefore earn revenue. Answer to Question No. ... Future-oriented routinely generated information for MCA refers to monetary carbon operational budgeting for short-term decision-making and carbon long-term financial planning long term decision making. Physical carbon accounting (PCA). For PCA, the past oriented routinely generated information includes carbon flow accounting for short-term decision making and carbon capital impact accounting for long-term decision making. The future-oriented routinely generated information for PCA refers to physical carbon budgeting in the short-term and long-term physical carbon planning for the long term. Both MCA and PCA are essentially interrelated. For instance, past-oriented monetary EMA relies on physical information regarding the flow of materials and energy made available by materials flow accounting approaches. On its own, however, past-oriented information is limited. It helps management discern sources of inefficiencies; thereafter, future-oriented information becomes necessary to forecas t the future effects of changes adopted at present (Abdel-Kader, 2011, p. 62). As for short-term information, this is useful where financial data is less volatile. When the data is characterised by high volatility, the long-term focus on carbon-related information becomes more suitable and reliable (Rajapakse & Wang, 2004). Answer to Question No. 3 Various factors influence the volume and type of information that an environmental management accounting (EMA) system provides. Among these are the number, type and functions of managers seeking information from the EMA system and the kind of decisions supported by this information. The structure of the organization and the manner in which its units relate to each other

Introduction Why Use OPNET Modeler Computer Science Essay
Introduction Why Use OPNET Modeler Computer Science Essay OPNET Modeler is a very good tool for network designing and simulation. OPNET Modeler was selected because most of the wired and wireless network components are available in the OPNET 15.0 Modeler. In this version a number of different models can be created to simulate, analyze and compare their results. This chapter explains how the different wired and wireless network has been designed and simulated in OPNET Modeler. In this project different scenario for Ethernet, DSL, Wi-Fi, and WiMAX in two different projects has been created in OPNET Modeler 15.0 . There is also a comparison between the wired and wireless networks. The Ethernet network is compared with the Wi-Fi network and the DSL network is compared with the WiMAX network. Overview of OPNET Modeler OPNET stands for Optimized Network Engineering Tool. The OPNET Modeler is a very powerful tool for the network modeling and simulation. The purpose of the OPNET Modeler is to optimize cost, efficiency, performance, viability and scalability characteristics of the network. In addition OPNET Modeler has a huge library of nodes(fixed, mobile or satellite), links(simplex, duplex, wired or wireless), and subnets, which are used to design and simulate network configuration, protocols, traffic and end user applications. OPNET Modeler has three hierarchical levels or editors. These are Project Editor Project editor is also known as network editor. The project editor is the key staging area for modeling a network simulation. In the project editor a network can be created by using the nodes, link, and subnets from the standard library, then select statistics, run the simulation and view the results of the network. FIGURE: Node Editor To built models of nodes the node editor is used. Node editor specifies the internal structure of the network node. The node includes workstations, satellite terminals, switches, and remote sensors. The OPNET node has a modular structure. The packets and status information are exchanged between modules which are connected via packet streams or statistic wires. Every module performs specific function, such as generating packets, processing packets, transmitting and receiving packets or queuing packets. FIGURE Process Editor The process editor is used to design process models, which controls the basic functionality of node models generated in the node editor. The process models are represented by Finite State Machines (FSMs). The FSMs are generated with icons, which show states and lines which shows transitions between states. The process models are expressed in C or C++ language. Figure In this chapter four different scenarios are discussed. These are Scenario1: Ethernet Network Model In this scenario a new wired network for Ethernet is created in OPNET Modeler as shown in figure. This scenario is created for campus network. In this scenario seven workstations are connected to the switch. With the help of a router the switch is connected to the server. The switch is connected to the router which is connected to the server. Ethernet links are used to connect all these nodes with each other. The server provides different applications used for the workstations. For this network model we also need to define the applications and profiles by adding a node for the application and profile. The workstations are associated with the profiles in order to use different applications. H:snapshots 1ETHERNET.bmp Figure Ethernet Network Model The nodes used in this scenario is Node Name Description Applications Profiles Server Router Switch Workstation How to configure Nodes The configuration of each node is as follow Application Configuration The application configuration is the most important node in the network design. By default the application configuration has a maximum of sixteen services, which are supported by the OPNET Modeler. These are http, ftp, e-mail, print etc. In this scenario the default services are selected as shown in the figure To configure the application node right click on it, select Edit Attributes a dialogue box will open. Change the name field value to application. Expand the Application Definitions row, select the default option while left other setting at default as shown in the figure. H:SNAPSHOT22)ETHERNET APPLICATIN CONFIG.bmp Figure: Ethernet Application Configuration Profile Configuration The profile configuration allows us to define a user or a group of user to the application services supported by the network. For this scenario one profile is defined namely shahid. The profile node can be configured by expanding the profile configuration row. Define the profile namely shahid also define the applications and change the operation mode to simultaneous while left the other setting at default as shown in figure To configure the profile configuration right click on it, select Edit Attributes a dialogue box will appear. Change the name field value to profiles. Expand the profile configuration row, select edit. Then define the profile namely shahid also define the applications and change the operation mode to simultaneous while left the other setting at default as shown in figure. H:SNAPSHOT22)ETHERNET PROFILE CONFIG2.bmp Figure: Ethernet Profile Configuration Server Configuration The server can generate the applications traffic such as http, ftp, e-mail, print etc. This traffic can be sent to the workstations with the help of router and switch which are connected through Ethernet links. In the server configuration, three applications supported services were defined namely http, ftp, and e-mail while all other settings are left at default as shown in figure. H:SNAPSHOT22)ETHERNET SERVER.bmp Figure Ethernet Server Configuration Workstation Configuration The workstation can also generate the applications traffic, which can be sent to the server through the network to the server. The workstation can be configured by selecting the Application Supported Profiles namely shahid while left all the other parameters at default as shown in the figure. H:SNAPSHOT22)ETHERNET WKSTN CONFIG.bmp Figure: Ethernet Workstation Configuration Router and Switch The functions of both the router and switch are almost the same. Both are forwarding the traffic to the end nodes. The router and switch are connected to each other through Ethernet link. Scenario2: WLAN Network Model In scenario 2 a wireless network model for WLAN is created in OPNET Modeler as shown in figure. This scenario is also created for the campus network. This scenario is similar to scenario1 with slight changes. In scenario2 the switch of scenario 1 is replaced with the wireless access point (AP) and also the workstations are replaced with the wireless LAN workstations. The main function of the wireless access point is to transmit and receive the wireless signals. The access point is connected to the router which is then connected to the server through Ethernet link as shown in figure. C:Usersshahid aliDesktopUntitlrgregreeddfgdfg.png Figure: WLAN Network Model The nodes used in scenario2 is Node Name Description Applications Profiles Server Router Wireless Access Point Wireless LAN Workstations The configuration of all the nodes except the wireless access point (AP) and wireless workstations are the same which are discussed in scenario1. The configuration of the wireless access point (AP) and the wireless workstations are as follow. Wireless access point (AP) configuration The wireless access point (AP) transmits and receives the wireless signals. The wireless access point can be configured by expanding the wireless LAN parameters. The access point functionality should be enabled so that this node can transmit the wireless signals. The BSS Identifier value is set to 0. If there is another wireless access point (AP) in the network then its BSS Identifier value must be different. The other setting is left at default as shown in figure. H:SNAPSHOT22)WLAN AP CONFIG.bmp Figure: WLAN Wireless Access Point (AP) Configuration Workstation configuration The workstation configuration is the same as the workstation configuration in scenario1. But in this scenario the BSS identifier value for the workstations is also defined. The BSS Identifier value is set to 0. This value must be the same as the wireless access point BSS Identifier value. The access point functionality is disabled for the workstations. The remaining settings are left at default as shown in figure. H:SNAPSHOT22)WLAN WKSTN APLICATION AND WIRELASS CONFIG.bmp Figure: WLAN Workstations Configuration Scenario3: DSL Network Model In this scenario a wired network model is created for the DSL using the OPNET Modeler. In this scenario four workstations are connected to the switch through the Ethernet links. The switch is connected to DSL modem. The DSL modem is connected to the DSLAM via the DSL links. The type of DSL used for this scenario is Asymmetric DSL (ADSL). The ADSL has a high downstream data rate than the upstream data rate. The function of the DSLAM is to linked several users to the high speed backbone network. The DSL modem is used to send and receive signals. The DSL modem has internal signal splitter that carries voice signal on the low frequencies and carries data signal above that frequencies. With the help of IP cloud the DSLAM is connected to the server via the PPP link. The figure shows the DSL network model. C:Usersshahid aliDesktopSHANPSHOT33DSL.bmp Figure: DSL Network Model The nodes and links used in scenario3 are Node/Link Name Description Applications Profiles Server Router Switch Workstation IP Cloud DSLAM DSL modem PPP Link DSL Link Ethernet Link The configuration of each node and applications taken for this scenario is the same as discussed in scenario1 and scenario2. For scenario3 the profile name is different, here the profile name is SHAH. Scenario4: WiMAX Network Model In scenario4 a wireless network model for the WiMAX is created using OPNET Modeler. This scenario is the same to scenario3 but there is a slight changes. A new node is added for the WiMAX configuration. Without this node the WiMAX network will not work. In this scenario the DSL modem is replaced with the WiMAX basestation, the switch is replaced with the subscriber station and the workstations are replaced with the wireless workstations. The WiMAX basestation will transmits the wireless signal over a long distance. The subscriber station which is found at the costumer site receives this signal, which is then sent to the wireless workstations. The subscriber station and the WiMAX basestation communicate through air interface-. The WiMAX basestation is communicating to the server through the ip cloud and router via PPP link. The figure shows WiMAX network model.

Puerto Ricans Immigrating to America Essay -- Puerto Rican History Cul
Puerto Ricans Immigrating to America The migration of Puerto Ricans to the United States occurred in two major waves. The first wave was in the 1910s-1940s and the second wave was from the 1960s to the 1990s. Each wave of migrants brought new generations of Puerto Ricans to the United States. Both waves of migrants believed that they were going to live a better life in America and migrated to major cities such as New York City, Chicago, Hartford, etc. The early migrants looked for industrial jobs such as in cigar factories while the later migrants found agricultural work such as in tobacco fields. The communities in which they lived grew larger and larger due to chain migration and because of this, the need for politics evolved. However, the type of politics that evolved as a result were different for each wave, yet had many similarities as well. If you would like to learn a little more about Puerto Rican migration itself, read Jamie Hellman's paper and Shakira Ramos' which goes into more depth. Class politics was the major form of politics that evolved during the early half of the twentieth century. According to Bernardo Vega, the tabaqueros were the only organized group in existence. They formed many clubs whose membership was not limited to Puerto Ricans only. Although the clubs consisted mainly of Cuban and Puerto Ricans, other people of different ethnic origins were members. One reason for this can be that the main leaders were exiles who had radical views and wanted change quick. Their concern was of homeland issues and they fought for independence from Spain. Concentrating on home issues, they paid no attention to their hostland (meaning America) issues because they lived with the belief that they were... ...from The Commuter Nation: Perspectives on Puerto Rican Migration," ed.

Aspergers
Espalier's Syndrome is a type of pervasive developmental disorder (PAD). These types of disorders (PAD) have delays Is the development of basic skills such as, the ability to socialize, to communicate, and to use Imagination. Children with Espalier's typically have normal intelligence and language development, but these could change as they get older. This disorder was declared official In 1944 by an Austrian doctor, Hans Aspirer. How Is Espalier's different from Autism? Children with AS don't have a delay in cognitive development or developing language skills.Children with Autism tend to have difficulty with symbolic thinking and pretend play. Another difference is the severity in symptoms, someone with AS can just be mistaken for a normal person behaving differently. Autistic kids will seem uninterested and stand-offish, where AS you want to fit in and interact with others (NAME). Symptoms of Espalier's can range from mild to severe, common symptoms are, problems with social skills , eccentric or repetitive behavior, unusual precautions or rituals, limited range of interest, coordination problems, lastly, skilled and talented (WebMD).I wouldn't necessarily say that the symptoms of AS are normal types of symptoms you would see In other disorders, but beneficial. Normal to above average Intelligence Is normal for AS but they usually have troubles with social Interactions. Anxiety, frustration, and depression are 3 common contributed behaviors. The cause for Aspirerâ⬠s remains unknown, but it has been seen to run in families so it could possibly be inherited. This disorder is classified under unique, the exact number of people with this disorder is unknown but they estimate 1 in every 250 children (WebMD).Studies say it is four times for likely to appear in males than females and is usually diagnosed in children between the ages of 2 and 6 years old (WebMD). Diagnosing Espalier's Is not the easiest, there Is no specific test that can tell you If you have Esp alier's Syndrome, you have to go through a series of test such as, x-rays and blood work. Doctors will also complete a physical examination because It has been see that patients with Espalier's have low muscle tone and dysphasia. If there is no physical disorder found you may be sent to see a specialist in childhood development disorders.There is no cure for Espalier's but there is treatment to elf improve. The treatments include special education, behavioral modifications, speech, physical and occupational therapy, and last, social skills therapy (WebMD). With effective treatment, children with Espalier's can learn to overcome or control their disability and repetitive tendencies. Adults with this disorder work successfully but sometimes still struggle with maintaining an independent life. All treatments work differently for everyone, some not at all. In an article on treatments for AS from Psych Central It stated that ââ¬Å"According to the National Institute of NeurologicalDisor ders and Stroke, the Ideal treatment for Espalier's coordinates therapies that address the three core symptoms of the disorder: poor communication skills, obsessive or repetitive routines, and physical clumsiness. â⬠Parenting a child with Espalier's is not easy, it has its difficulties. If you have a child who has been yourself you will be able to help your child grow to their fullest. A daily schedule has shown to help a lot. In the schedule include specific times for therapies, school, meals, and bedtime. If you have to make a change to the schedule, alert your child forehand so they can adjust.Having a ââ¬Å"safe placeâ⬠in your home will benefit your child because they will have a place to relax and feel secure. Children with Espalier's tend to get irritated somewhat quickly, causing them to lash out, if your child does so, sending them to their safe place can help them collect, and calm down. A main concern with parents who have a child with AS is their social life at school, ââ¬Å"will my child have friends? â⬠is a common question most parents ask. Most kids still live a normal social life throughout school. They make new friends; it's Just harder on some Han others.Identifying children with the same interest as yours can make it a lot easier on the child. Encouraging your child to develop their strengths and interest and to Join clubs or participate in any after school activities is a great way for their social skills to become stronger, especially as they grow older and move into middle/ high school. Many people don't know when a child has AS because it is so hard to see, it's not like other syndromes or disorders that develop physical traits. When you are the sibling of an AS patient it can also be stressful for you.Some siblings can come Jealous or embarrassed of their brother/sister because the parent(s) focus more of their time and attention on them. Some siblings may need to learn how to look out for themselves because some AS p atients have a hard time controlling their frustration or anger. Sticking up for a brother/sister whom suffers from AS is the best thing a sibling could do, it shows that even though you may not always get along, you love them and care for them. This can make them feel accepted or normal because it's something that a ââ¬Å"normalâ⬠sibling would do for another.I have a younger sister who has AS and it can be hard. She is 8 years younger than I so we tend to bicker. When she is put in a situation where she has to be independent, say ask a stranger for directions, she becomes very nervous and her anxiety shoots through the roof. If she is upset and you continuously ask her what is wrong, she will lash out and become violent. Sometimes she won't remember what she said or did. When she has these tantrums we usually let her calm down and relax until we confront her about them. Sports and horses have been a huge help with her anxiety and AS.By interacting with other kids her age she has learned to be less socially awkward. Medications does play a role in her daily life, she takes medicine once a day at night before bed. The medication is supposed to help with her anxiety and aggressive tendencies. Not only do children struggle with AS but so do adults. An adult with AS may have difficulties understanding other people emotions, they can misinterpret others facial expressions and body language for something else. This can cause someone with AS to come off as selfish, egotistical, or uncaring (Better Health).When a person with AS is notified about their actions they may come off as shocked and set because neurologically they are unable to understand other people's emotions. Overall adults have a better understanding of their strengths and weaknesses; they are able to learn social skills People think that Just because you have a disability, it means you can't have a romantic relationship with someone. Adult with AS still have romantic relationships, according to t he Better Health Channel ââ¬Å"Studies suggest that many struggle with the myriad of complex skills required to successfully negotiate intimate relationshipsâ⬠.Sometimes they can come off as inappropriate or immature cause they are unaware of what is right and wrong to say or do. When in a relationship, a partner can become frustrated because of unfair distribution of responsibilities. When the partner expresses their feelings of frustration to the AS partner, they come off baffled because they don't realize what they are doing. Having a career and being an AS patient is very normal, you could be working with someone with AS and not even know it. People with AS can excel in a lot of different areas, such as mathematics, music, or being visually creative.Some careers for AS patients that re visual thinkers are computer programming, drafting, photography, or equipment design (Better Health). If you are a music or math fanatic some career choices may be accounting, telemarketer, pianist, or a Journalist. Working with an AS person is not hard, communicating clearly is a good way for your AS employee to work to their fullest ability. Only expect one project at a time, putting too much stress on them can cause anxiety or them to lash out. Being specific with what you want from them is another way for them to be the best employee.When they know what is expected room them they will give it, Just like any other employee, you Just have to be clear, straight forward, and specific. AS employees are seen to be the most hardworking and dedicated employees a business could have. In conclusion to my research paper, I think that Espalier's Syndrome is a rare diagnosis that carries beauty. These people are so bright and intelligent that you'd never even know they had AS. They live normal lives and have good Jobs Just like a number of normal people. They may have some social setbacks here and there but with time and the right treatments they can overcome anything.I think t hat everyone should be given an equal chance no matter what they're disability may be. My sister being 12 and a AS patient, she is heading into middle school, a stressful time for someone with AS. Between her therapies and medications she has learned to control her symptoms and by participating in after school activates, even though they might stress her out, she has gained so many friends, more friends than I ever did in middle school. I hope this paper helped you learn about Espalier's Syndrome and can help you understand more of what it really is.

Successful Writing of a Linguistics Term Paper
Successful Writing of a Linguistics Term Paper Writing a term paper is a difficult task for many students, especially during the first years of studying. Students tend to be frightened by the prospect of writing term papers because this type of work usually accounts for a large part of the semester grade. Thus, if a student wants to avoid the struggle and any doubts, he or she should consider the basic principles and guidelines for the successful performance of the work. To be more precise, checking the specific rules for writing a paper in a particular field should be the first step in the process. To help achieve the highest academic goals, this guide focuses on the practical principles for writing a linguistics term paper with ease and confidence. What Is a Linguistics Term Paper And How Does It DIffer from a Research Paper? A term paper in Linguistics is an original academic work that covers the specific topic with the consideration of relevant theoretical literature and empirical studies. The paper deals with a scientific study of either single or several languages. Linguistics term paper can be theoretical and empirical (practical). Depending on the chosen approach for the study, the structure and the content of a linguistics paper would differ. Furthermore, while some people tend to confuse a term paper and a research paper, there are several differences between them. A term paper contains a critical examination of a topic and the studentââ¬â¢s opinion. In this type of work, a student is required to demonstrate a profound understanding of the topic and to present convincing arguments supported by credible scholarly sources. On the contrary, research papers are written to study a theoretical question which has not been researched effectively. A research paper may be more complicated because the writer is supposed to conduct research, provide the collected results, and to connect them to the analyzed academic literature. A term paper may also contain the parts of the research if the student considers the empirical approach of writing. Understanding the goal of a certain type of paper is one of the keys to proper writing. What Students Are Expected to Demonstrate in a Linguistics Term Paper: they have acquired proper knowledge in a particular field; they can choose a topic relevant and significant to the specific field; they learned how to collect, analyze, and use academic sources in a paper; they can make own conclusions based on the studied literature; that they can follow the principles of academic language and style. While writing, it is important to remember that the main goals of the term paper are to review information learned over an academic term and to develop a better understanding of a particular topic. How to Choose a Suitable Topic? The topic of the work can be assigned by the professor, or students can choose it by themselves. The second option is preferable because in that case, people study a subject that is interesting to them. Once the field of the study is identified, it is possible to start looking for a topic worth investigating. In choosing a topic, the most important aspect is to be specific and avoid generalization. For instance, if a writer chooses the branch of Stylistics, the bad example of the topic may sound like ââ¬Å"Characteristics of Science Fiction.â⬠Instead, a more sophisticated topic in that area suitable for the research may look like â⬠Linguistic Aspects of Science Fiction Genre in Modern Literature.â⬠Below are some other examples of good and bad topics to help you. Examples of good topics: The Interplay of American and British Versions of the English Language at Present Time; The Comparison of Linguistic Politeness of the Japanese and English Languages; The Use of Acronyms and Abbreviations in English Informal Communication; Word Formation in Slang Language of the U.S. College Students. These topics are specific and reflect the narrowed area of the chosen field. Examples of bad topics: Origins of the English Language; Why is Linguistics Important? Introduction to Translation; The Comparison of the English and Japanese Languages. These topics are too broad, meaning that it would be difficult to provide a comprehensive analysis of any of them in a paper. Moreover, some other things to consider when choosing a topic is the level of expertise in the particular area and the availability of the sources. If the subject is too difficult, it will be troublesome to finish the paper. Also, before starting to write on a chosen subject, it is necessary to determine whether there is enough information for the study. Students may begin by searching for the keywords and titles of the topic on the Internet search engines and then proceed to library databases. Structure of the Linguistics Term Paper as Explained by Our Writers As it has been discussed, the linguistics term paper can be theoretical and empirical. Most term papers are required to utilize both approaches to the study. Hence, below is provided the structure of an empirical term paper: Title Page (a title of the paper and students name); Table of Contents (a list of sections with page numbers); Introduction (description of the area of research, the question posed in the paper, the reason for the study, and a brief overview of the research); Theoretical Part (reflection on the literature studied for the paper and demonstration of an understanding of the major concepts of the area); Research Methodology (relation of the ways the data was collected and analyzed); Results (presentation of the findings based on the methodology); Discussion (interpretation of the findings and explain their significance); Conclusion (summary of the paper and statement of the answer to the posed question); List of References (a list of literature and other sources used for writing the paper). The introduction and theoretical part should not constitute a large part of the paper. These sections should account for less than half of the paper. The larger part of the text belongs to the remaining sections. The term paper incorporates most sections of the research paper, plus the theoretical part. If a paper must be completely theoretical, such sections of the research paper, as the methodology, results, and discussion can be removed. They can be replaced with a more elaborate investigation of relevant theoretical literature to reflect on the topic. Drafting the Outline The outline is an essential part of the writing process, especially when it comes to larger texts. Drafting an outline will help create a well-structured paper with a logical connection of ideas. While writing an outline, it is necessary to remember that is it based on the structure of the paper. Any outline contains the major elements of the essay, that is the introduction, body, and conclusions. Students should start planning with these three basic elements and then proceed to add more sections to the outline. The Theoretical Background For the theoretical part of the paper, the student is required to analyze and reflect on a great amount of information collected from a variety of sources. While writing this section, the student studies the articles from different specialized linguistic sources, such as the scientific journals, textbooks, and dictionaries. First of all, in the theoretical part, a writer should state the essence of the posed question or studies problem. Then, he or she needs to provide a theoretical framework of all components of the problem and analyze them from different perspectives. Next, discuss the research that has been already done on the problem. One of the important aspects of the theoretical part is presenting and explaining terminology relevant to the question. Finally, in case a term paper has an empirical part, a writer must state a hypothesis which will be supported with the data in the next sections. What to Include in the Methodology Section? An empirical study typically requires the section for methodology. In brief, this section states which method was used to acquire the data and how it was analyzed. Depending on the type of research, the methodology in a Linguistics paper may include the details about the subjects, materials, techniques, corpus, and the procedures of the research. The methods to use largely depend on the essence of the research. For instance, if the study includes human subjects, some useful methods for linguistic research would be a questionnaire, observation, and interview. The elements of the methodology section also depend on the type of data. Thus, in research which presupposes the use of subjects, it is important to characterize the chosen subjects (e.g., age, nationality), state the used materials (e.g., questionnaires), as well as to indicate the procedures (e.g., time, setting) of the specific ways the data was collected. For the research which is based on the study of corpora, students should describe the corpus design and briefly explain the reason for choosing it. Also, they should not forget to mention the problems that were encountered while collecting the data and show the way these hardships were managed. Finally, once these parts of the section are covered, it is necessary to state the process of the analysis and categorization of the collected data. The Main Points of the Results and Discussion Sections In the Results section, students must provide a detailed description of the findings that were discovered during the research. A convenient way to present quantitative data is by including graphs and tables. However, do not just include them without any explanation. Briefly discuss the material presented in the tables and graphs. In the Discussion section, writers usually give a summary of the results and connect the findings to the theoretical background. Finally, comes demonstration how the results help answer the questions and hypothesis stated in the paper. How to Find Sources? A good list of sources is one of the keys to the successful writing of the paper. Most relevant material appropriate for academic work can be found in research published in scholarly journals as well as textbooks, encyclopedias, and dictionaries. For instance, Open Journal of Modern Linguistics, Journal of Sociolinguistics, Encyclopedia of Language Linguistics, a variety of Oxford Textbooks in Linguistics. Probably, the primary source for searching information among most students is the Internet. Search for the keywords of the chosen topic online. It is useful not to search the whole Internet, but to consider specialized websites which collect scientific works and references to them. Below are some of the examples of such websites with either open or limited access to sources and references: journals.sagepub.com scholar.google.com books.google.com openlibrary.org researchgate.net ebsco.com worldcat.org If a paper considers corpus as the base for the research, the sources discussed above should serve as the secondary material. The primary material should be the actual linguistic data in the form of either written text or audio recordings. For example, letââ¬â¢s suppose that a task supposes corpora in the English language. In that case, some of the examples of available corpora which can be used as the primary material are: The British National Corpus; Corpus of Contemporary American English; The International Corpus of English. Many other websites for exploring English corpora can be found here. While the Internet is a good source for finding information, students should not forget to visit the college library to discover scientific literature. In addition, some schools provide access to various closed online libraries and databases, so do not hesitate to check if they contain any useful sources. Citation of Sources Many students struggle with citing the sources properly. An instructor may demand to write a term paper in a certain style, whether APA or MLA. Depending on the style, the citations can vary. All information and instructions on proper citation and referencing can be found on the Owl Purdue Online Writing Lab. Since the APA formatting is usually a preferable style for papers in linguistics, here are some of the examples of proper APA citations: Martin, J. R. (2009). Genre and language learning: A social semiotic perspective. Linguistics and Education, 20(1), 10-21. doi:10.1016/j.linged.2009.01.003. Radford, A., Atkinson, M., Britain, D., Clahsen, H., Spencer, A. (2010). Linguistics: An Introduction (2nd ed.). New York: Cambridge University Press. Also, do not forget about in-text citations and paraphrasing. Direct citations in APA style, require the page number. For example: ââ¬Å"A central idea of Relevance Theory is that an utterance is relevant to a hearer when the hearer can gain positive cognitive effects from that utteranceâ⬠(Radford et al., 2009, p. 399). What to Do Next? After finishing writing the paper, there should be no rush to submit it to the teacher. Many students tend to overlook various mistakes which can significantly decrease their grade for the term paper. Proofreading the paper is one the most important steps in the post-writing process. Sometimes, it may be difficult to notice minor mistakes in such a big text, so it is recommended to let somebody else proofread your term paper. Moreover, the presented ideas should be logically connected to make the general sense of the paper. To understand whether a paper is ready, these questions could challenge it: Is paper well-structured and properly divided into paragraphs? Does each paragraph have one main idea? Do all of the discussed ideas support my thesis? Are all ideas taken from the sources cited? Are all of my citations explained? Does paper have any grammatical, stylistic, or lexical mistakes? Does the paper correspond to the required formatting? Once all works in polishing the paper are finished, a writer can be proud of the final work. The stated above information should be kept in mind for writing the next papers.

The Golden Age of Microbiology essays
The Golden Age of Microbiology essays What would the human race be like if we did not have some of todays modern medicines? It would probably be just like it was 200 years ago. Doctors claiming to know cures forsome of the worlds most infectious diseases, and then treating them in the some of themost inhuman ways. People would be dieing from infections left and right. And even worse, we would not know how to cure most of their diseases. The world populationwould probably be half the size that it is today. But, thanks to the Golden Age ofMicrobiology, and the people who tried to find cures and such, we now have ways to over come most of the worlds diseases. The Golden Age was only 20 years long, from 1880 to about 1900. It was the time when about three scientists helped to better sciences technologies and cures. The first of these three was Pasteur. Some of his contributions to science were the creation of silk and a cure for rabies. But one of the most important of all of his findings was the idea of pasteurization. Around the time of 1870, there was a problem with the making of beer and wine. The companies could not figure out a way to keep their products from becoming sour. Pasteur then came up with the idea of adding many different elements to the products and then refrigerating them for a long period of time. Thus came the idea of The second out of the three was Robert Koch. Koch was mostly into the study of microbiology and bacteriology. Most of his researching was done under the microscope, but he realized that he could not totally determine what a certain bacteria classified as. He discovered that if you were to add a stain to slide that you would be able to make out the bacteria about 10x better. Koch also noticed that sometimes you cant always find bacteria in just one sample of something that is contaminated. So, he came up with the ...

The Effects of Frederick Taylors Scientific Management Essay
The Effects of Frederick Taylors Scientific Management - Essay Example Taylorââ¬â¢s theories can be seen in many organizations that exist today, but perhaps most easily in the processes that characterize the popular fast food chain McDonalds, especially if one studies the means by which the company has redesigned their work areas to produce the greatest possible product in the least amount of time with the fewest manpower hours necessary to keep customers happy. Taylorââ¬â¢s theory centered around the concept that management and the workforce should work in tandem for a mutual benefit, but that it was essential for management to make benefits directly applicable to the employee who worked hard. He noted that ââ¬Å"there is no question that, throughout the industrialized world, a large part of the organization of employers, as well as employees, is for war rather than peaceâ⬠(Taylor, 1911: 67). In order for an organization to prosper, Taylor argued, it was necessary for the organization to enable and encourage the employee on an individual basis to reach their full efficiency. ââ¬Å"In a word, that maximum prosperity can exist only as the result of maximum productivityâ⬠(Taylor, 1911: 68). The only way to encourage the individual to strive to their full efficiency, though, was to enable them to receive some kind of direct benefit, such as a higher wage for a higher productivity. This involved not only the establishment of a workplace that was conducive to the human body and its needs in performing the tasks at hand, but also to training and personal development among staff members. One of the ways of accomplishing this goal was by direct wage increases based on an individualââ¬â¢s increased productivity or expertise. Another was through the efficient organization of the production floor.

American History X Research Paper Example | Topics and Well Written Essays - 750 words
American History X - Research Paper Example While in prison, Derek decides to take a new turn after a visit by his former Black English teacher Dr Sweeney. A brutal rape by Aryan Brotherhood prison gang fuels the transition after his defection. However, on leaving prison, Danny had stepped in his shoes and joined Neo Nazi movement. Derek has to fight to achieve a new life for himself and Danny. The film is full of flashbacks, employing the language of racism to capture sophisticated variations. On TV news, Derek narrates how his father had tutored him to racism through his dinner table conversations not forgetting his death in the hands of black narcotics. The film is full of scaring scenes and convincing scenes that reveal Neo Nazi skin heads bonding. In their meetings led by Derek, they take drugs, beer, engrave tattoos, and carry heavy metal with them. In the Neo Naziââ¬â¢s world, slogans replace thought, fuelling a mindless hatred towards their black enemies and the film brings out the best of this movement. Neo Nazi mo vement comes out strongly from American History X film. Neo Nazi movement also called skinheads have their origin in England after World War II. According to Prejudice Institute, ââ¬Å"the first wave of what we today recognize as skins polarized themselves in the 1970s. This happened against the various youth counterculture movementsâ⬠(ââ¬Å"Prejudice Instituteâ⬠web). ... In 1980, a second wave of this movement was in action when Ian Stuart founded Neo Nazi movement. Apparently, he was a singer and the leader of the Screwdriver band that played an important role in the spread of the movement. The group identified themselves by Nazism and belief in white power and they portrayed it through their way of shaving heads, tattoos, t-shirts, and their confrontational style. Neo Nazi movement cemented its operations in the 1990s because it took advantage of independence war and other ethnic conflicts in of Croatia. To catch the attention of the media, Neo Nazi movement brutally attacked tourists and foreigners, gay people, and people from other cultures. According to Libcom, some of their memorable attacks came in 2003 when Neo-Nazi skinheads attacked six people including five old people and 11-year old boy from Egypt (Kontrrazvedka web). Neo Nazi has links with order supremacist groups like KKK and White Aryan resistance (WAR). Stuart published books by name blood and honour that he distributed to older white supremacies in the US to gather membership. Statistics reveals that skinheads age range from 13 to 27 years mostly teens from various social economic backgrounds. Most get to enrol in high school and continue through college and at work. Recruitment happens at the concerts that attract many young people to listen to Neo Naziââ¬â¢s music and performances. For instance, Screwdriver songs like White Power and Nigger performed mainly on Hitlerââ¬â¢s birthday or at Hate Festivals are tools of transformation. Skinheads also use publications and cyberspaces to promote their ideas and recruit members (ââ¬Å"Prejudice Instituteâ⬠web). According to Cooter, the group have adopted a new tactic for

HRD Case Study Example | Topics and Well Written Essays - 500 words
HRD - Case Study Example s in which the acquired companies used when going into market but also rethinking how various business parts could be integrated on a global perspective. Specifically, Mr. Grunewald required finishing market research so that the organization can acquire adequate information prior to entering the market, simplifying the existing production design, rationalizing the distribution channels, and most importantly overcoming regional differences. The companyââ¬â¢s recent improvements were the result of a commitment that was met. This involved a four-part strategy that concentrated the organizationââ¬â¢s resources as well as energies on a clear set of objectives. These objectives incorporated building the organizationââ¬â¢s core profitability, strengthening its management, broadening the returns, and improving returns on equity. Through application of such managerial aspects, the organizationââ¬â¢s direction was reversed from the verge of collapse due to customer dissatisfaction and tarnished reputation to a global power surpassing most of its previous performance records. The organizationââ¬â¢s current performance is being driven by several factors. First, the urge to re-establish its reputation and its market share in the global perspective is pushing the organization to shift the mode of thinking from the local perspective to global. Second, competition in most segments of the local market has also pushed the organization to improve its practices and focus on bigger and broader opportunities in the global arena. Black & Decker has taken the issue of competition seriously to the point that it has even reverse engineered some of the competitorââ¬â¢s products to manufacture better products with respect to technology and security. One of the strengths include that the proposal had accounted for the major aspects that would be essential to establish the organization in the projected markets. The proposal had catered for communication among the branches and established an idea of the

For the duration of the connection, all the resources on that circuit are unavailable for other users. Voice calls using the Internets packet-switched system are possible. Each end of the conversation is broken down into packets that are reassembled at the other end. The principles of packet switching are as follow. Messages are divided into data packets, which are then directed through the network to their destination under computer control. Besides a message portion, each packet contains data concerning. The principles of packet switching are as follow. Messages are divided into data packets, which are then directed through the network to their destination under computer control. Besides a message portion, each packet contains data concerning: Ã The destination of the address; Ã The source identification; The sequence of the packet in the complete message; Ã The detection and control of transmission errors. Ã Pre-determined routing. With this method, the routing details are included in the packet itself, each switching exchange forwarding the packet according to the embedded instructions; Ã Directory routing. Each switching exchange has a copy of a routing table to which it refers before forwarding each packet. The appropriate output queue is determined from the table and the packet destination Diagram shown below: Identify three types of cabling used in data communication. State which one you would recommend in an implement requiring high security consideration and why? The three types of cables used in data communication are: Optical Fiber Coaxial Coaxial cable is a copper that is used by TV companies between the community antenna, and also the user homes and businesses. At times these cable are also used by telephone companies from their central office to the telephones near users. This is also widely installed for use in business and corporation Ethernet and other types of local area network. Coaxial cable is called coaxial this is because this includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as a ground. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters, they can carry information for a great distance. This is a diagram shown below: UPT UPT stands for Unshielded twisted pair. This cable is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed into a shield that functions as a ground. This is known as shielded twisted pair (STP). The twisted pair is now frequently installed with the two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for use of a modem) when you will need it. These twisted pair comes with each pair uniquely colour coded when it is packaged in multiple pairs. Different uses such as analogue, digital, and Ethernet require different pair multiples. Although twisted pair is often associated with home use, with a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive than coaxial cable. The wire that you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of hole arrangements or pin outs, depending on what kinds of wire the installation you expects that will be plugged in (for example, digital, analogue, or LAN) . (Thats why you may sometimes find when you carry your notebook computer to another location that the wall jack connections wont match your plug. ) This is a diagram shown below: Optical Fiber. Optical fiber (or fiber optic) refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber. Optical fiber carries much more information than the conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals. Most telephone company long-distance lines are now of optical fiber. Transmission on optical fiber wire requires repeaters at distance intervals. The glass fiber requires more protection within an outer cable than copper. For these reasons and because the installation of any of the new wiring is labour-intensive, few communities yet have optical fiber wires or cables from the phone companys branch office to local customers (known as local loops). A type of fiber known as single mode fiber is used for longer distances; multimode fiber is used for shorter distances. This is the diagram shown below: By analyzing and researching the three above cable I would recommend the Fiber Optic cable this is because I believe it has a high security and also has the following. Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data. Ã Fiber optic cables are less susceptible than metal cables to interference. Fiber optic cables are much thinner and lighter than metal wires. Data can be transmitted digitally (the natural form for computer data) rather than analogically. Identify the alternative forms of communication media and provide examples of their use in different forms of network. Microwave Microwave frequencies require a direct line of sight between sending and receiving station to operate. Microwave systems were the preferred method of communications transmission before the introduction of fiber optic. Radio The lowest-frequency domain that needed to name. This extends from wavelengths of a kilometre or so, the longest that will propagate through the interstellar medium, down to about a millimetre. The detection of radio radiation is often done using wave techniques rather than photon-counting, this is because of the low photon energies, and this offers distinct advantages for such applications as interferometer which astronomers working in the infrared and optical regimes view with some envy. From active nuclei, we often detect the synchrotron radiation in this range radiation produced energetic charged particles (mostly electrons) produce when they are deflected by the magnetic fields. a) Define the basic signal theory with the aid of diagrams? 1) In electronics, a signal is an electric current or electromagnetic field that is used to convey data from one place to another. The simplest form of signal is a direct current (DC) that is switched on and off; this is the principle by which the early telegraph worked. More complex signals consist of an alternating-current (AC) or electromagnetic carrier that contains one or more data streams. Data is superimposed on a carrier current or a wave this is by means of a process called a modulation. Signal modulation can be done by two main ways: analogue and digital. In recent years, digital modulation has been getting more common, while analogue modulation methods have been used less and less. There are still plenty of analogue signals around, however, and they will probably never become totally extinct. Except for DC signals such as telegraph and base band, all signal carriers have a definable frequency or frequencies. Signals also have a property called wavelength, which is inversely proportional to the frequency. 2) In some information technology contexts, a signal are simply that which is sent or received, thus including both the carrier and the data together. 3) In telephony, a signal has a special data that is used to set up or control communication. Almost everything in the world can be described or represented in one of two forms: analogue or digital. The principal feature of analogue representations is that they are continuous. In contrast, digital representations consist of values measured at discrete intervals. Digital watches are called digital because they go from one value to the next without displaying all intermediate values. Consequently, they can display only a finite number of times of the day. In contrast, watches with hands are analogue, this is mainly because the hands move continuously around the clock face. As the minute hand goes around, it not only touches the numbers 1 through 12, but also the infinite number of points in between. Early attempts at building computers used analogue techniques, but the accuracy and reliability were not good enough. Today, almost all computers are digital. Analogue and Digital Technology Analogue and Digital are the words we hear when people talk about Communication and Information Technology. What do the words Analogue and Digital mean? Analogy means a likeness between two things that are really quite different. For example the analogy between the brain and the computer or the heart and a pump. Digit means either a finger or toe, or one of the numbers 1 to 9. Some examples might help to explain what analogue and digital mean in technology. A simple example of analogue and digital technology Clocks are examples of analogue and digital technology. An analogue clock face can display the time without numbers. The hands keep moving all the time and they continue to rotate, just like the earth around the sun. This is the analogy between the movement of the sun and earth, and the hands of the clock. The digital clock displays the time in numbers, and the time displayed only changes at each minute. In the analogue clock the hands keep moving all the time, while the digital clock is more like an on and off movement. Each minutes the time moves and then stops for another 60 seconds, when it changes again. Some other examples of displaying information using analogue and digital forms. b) How the signal theory affects the choice of transmission methods and media? Analogue and Digital Signals Sound can be converted into analogue and digital electrical signals. Analogue Signal A microphone or handset of a telephone will convert sound into an analogue signal. The shape of the wave seen on an oscilloscope represents the volume and pitch. The diagram is shown below: This is called an analogue signal because, when the volume and pitch change, so does the shape of the wave. The signal is an analogue of the sound. Digital signal Today we see many sound systems described as digital. This means the sound is converted into digital signals so it can be transmitted or recorded. In the microphone example shown on the diagram above, the analogue signal is converted into a digital signal by electronic circuits. In a digital signal the electricity, this can be either on or off, is combined with a binary code. The voltage of the analogue signal is measured electronically, many thousands of times per second, by an analogue-digital converter. The analogue signal is converted into a 16 bit binary number, which gives 65,536 levels of voltage. In electronics 1 = ON and 0 = OFF. This means the binary number can be converted into an electrical signal. A diagram below shows the process of converting analogue signals into a binary numbers and digital signals. To keep the explanation simple the analogue signal has been converted into a 3 bit binary number, which means there are seven voltage levels. A digital-analogue converter reverses the conversion this is because the speakers (output device) need an analogue signal. Light and sound can be converted into binary numbers and digital signals that are used to record and transmit information. This diagram is shown below: Why are digital systems better than the analogue ones? An analogue signal is affected by changes in the voltage as it travels along a wire. If the voltage changes, so does the signal at the output. The digital signal is not affected by changes in the voltage this is because all that matters is whether it is ON or OFF. How signal affects transmission methods? Noise is any sound on the CD or record that wasnt there at the performance during the recording session. More generally, it is any unwanted signal that adds on to the information that is being transmitted. When a vinyl record is being made, noise is introduced at every step of the recording process, although of course the company makes an every effort to reduce such noise to as low a level as possible. The sound that reaches the microphones is converted into an electrical signal that is then recorded on a wide magnetic tape moving at high speed. This tape is then used to control the cutting of a master disc, from which moulds are then made. These in turn are used to mass-produce the records that are eventually sold in shops. Noise is produced at every step, not forgetting that introduced by your own stereo equipment. It can never be entirely eliminated. The same problems of noise are shared by any method of transmitting information, and are certainly by telecommunications, including telephone calls. In the production of vinyl records, the companies have used purely analogue this means to transfer the information representing the sound of the music from one point to another. That means they use an electrical signal that changes smoothly in strength, exactly modelling the smooth but complex changes in the sound. When a noise is created in the recording process because of tape hiss, dust on the master disc, electrical interference or any other cause this is added on as a random signal on top of the complex electrical signal representing the sound. There is no way that electronic equipment can tell such random noise from the original electrical signal, so there is no way it can be removed again without removing some of the original signal. We can see more clearly if we draw a graph of the level of the analogue audio signal over a period of time (diagram 1a). The shape of this graph represents both the changes in the electrical sound and the changes in the electrical signal that model it. Now if we add to this audio signal some random noise, this affects the shape of the signal, and this degrades the sound that your stereo reproduces (diagram 1b). The trouble with an analogue audio signal is that its exact shape has to be preserved if you are to hear the music exactly as it was when it was played. If there were a means of transmitting the signal so that only the overall shape of the signal mattered, then noise would not be so important. The port authorities used to find the shape of the bottom of the harbour, so that ships could navigate more safely. It certainly wasnt possible to drain the harbour and take a photograph of it, so what they did instead was send out a boat which travelled slowly across the harbour. Every few meters a person at the back of the boat dropped down a plumb-line (a weight at the end of a rope), until it reached the bottom of the harbour. The line had knots tied in it at regular spaces and the person called out the number of knots under water, so indicating the depth of the harbour at that point. A clerk wrote these down, and eventually it was possible for him to draw a graph of the shape of the harbour by using these numbers. The person in the boat had been taking samples of the depth of the harbour at frequent intervals, so that the graph would accurately describe the ups and downs of the harbour bottom.
