The reason for good grammar use is to guarantee th Essays

The reason for good grammar use is to guarantee that what you write is effectively appreciated and is simple and pleasant to read. Yes, I believe my grammar has improved drastically since the beginning of this course. One tip I learned from the Grammar review h andout was how to use punctuation with quotes: Periods and commas always go inside the quotes. I have never really had to use correct grammar so this review really helped me a lot. Yes, I feel better using commas, commas have always been a problem for m e, especially run on sentences. A fter taking this class , and reviewing the lessons, it has become clearer when and how to use commas, such as adding a comma and a coordinating conjunction. It is important to use outside sources to provide supporting documentation to what you are writing about, the best way to tell the difference between a good and bad source is to use credible sources, such as, school library, or google scholar. The difference between p araphrasing and plagiarism is , paraphrasing is a re-statement of something that was a written or spoken phrase and not crediting the original author in your citations . Plagiarizing is when you copy word for word from outside source and not credit the author . The difference is that paraphrasing is using an idea that you have read, plagiarizing is when you use someone else's work word for word. One way I will a void plagiarism in the future is not to copy more than two words in a row without using quotations and correctly citing my work in papers.

October Sky Summary Essays

October Sky Summary Essays October Sky Summary Paper October Sky Summary Paper The story told In Joe Johnnys film October Sky (1999) Is a beautiful one and a true one. I was really enthusiastic to watch this movie, because I love to watch movies based on true stories. I find they teach us many lesson through their experiences. The four teenage boys Homer Hickman, Question Wilson, Roy Lee Cooke, and Sherman ODell are very devoted to fulfill their dream of rocketry. The boys are first inspired by the Sputnik 1, the first satellite launched into the earths orbit. But everyone in the town of Coaled is destined to become coal-miners, unless they are lucky enough to et a football scholarship. To everyone coal-mining was Homers only future, Just like his father. Homer and his friends fearlessly begin learning how to build rockets and testing them. The whole town is not behind them and believe theyre wasting their time, especially Homers father John Hickman. The only one who strongly supports them is their teacher, Miss. Riley. She tells them that they can contend in The National Science Fair. The prize being college scholarships. By examining their experience you learn a lot about striving to achieve a goal, no matter what the odds. Homer has always rebelled against the coalmine and his fathers wishes. He Is very hopeful for his dream of doing rocket science and wont stop until he reaches it. He cares a lot for his family and the people around him, especially Miss. Riley. When Homers father got injured and couldnt work in the mine temporarily, Homer understood that he had to give up his dream and work in his fathers place. But it is until Miss. Riley grow sick and Homer visits her, then she tells him Sometime you really cant listen to what anybody else says, you Just got to listen inside. His ambition is renewed. Homer leaves the mine and continues to go into The National Science Fair, he get excepted. He ends up winning the gold metal, and he and his friends all earn scholarships. Miss. Riley has always been such a support for Homer. She always stuck out for him in the hopes that he would make a difference. When the boys were in the lunchroom looking at their rocket, the principal didnt allow the rocket in his school. Miss. Riley covered for them saying they were planning to enter The National Science Fair. She brought hope to the boys, even though they didnt seem like the smartest kids around. She never stop at anything even as she was dieing and Homer seemed to have given up his dreams. As for John Hickman he did not support Homer in any of his efforts. In fact he was against him. The only thing that seemed Important to him was his pride, the coalmine, and Coaled. When Homer lets go of his dreams to work in the mine John was very proud and begins to finally prelate but when Homer goes on continuing rocketry he doesnt support him at all. Until his wife, Elsie begs him while the strike Is going on to help Homer when his rocket part were stolen in the science fair. John Bolder Dont you have work to do? John learns that going difficulties and even scaring his pride is important to achieve his goals. After Homer goes home he and the boys decide to shoot their last rocket. Homer asks his father if he would come watch them shoot their last rocket, but he excuses him for his work. Then Homer tells him l only hope I could as good as a man as you are Sure Dry von Braun is a great scientist, but he isnt my hero. John was stunned by that and later ends up watching Homer and the boys shoot their last rocket. For the first time John is completely behind his son. Looking at their experiences and the consequences they had taken, it really reflected to the theme of the movie. They would have never achieved any of their goals if they hadnt tried their hardest even against all the odds. Homer does whatever it takes to achieve his goals, he walked 8 miles off company property to test his rockets when his father banned him. He still had hope even when the boys were charges for starting a forest fire. And even after working in the mine Homer decided hed quit and continue rocketry, knowing his father would be disappointed. Miss Riley is very caring and understanding, and tries to help Homer and the boys in anyway she can. She motivates and believes in them, causing her to strive and do whatever it takes in the hope of achieving something. Even as she was laying in the deathbed. She did everything she could to support these boys. The best representation of this theme is when John Hickman didnt stop at anything to save the people from the mine, even if it meet risking his life. For he saved many lives from this action. All of them made sacrifices and had consequences but they all had good results. This story shows the achievement people made, with no hesitation to strive to make a difference.

Dominican-American Convention of 1907 Essay Example | Topics and Well Written Essays - 250 words

Dominican-American Convention of 1907 - Essay Example Second, the Dominican debt included American creditors and the United States wanted to see that they were paid and American control of Dominican finances made this more likely. The principle that the United States would force countries in the western hemisphere to pay their foreign debt is the Roosevelt Corollary of the Monroe Doctrine. Third, the United States wanted to make a statement and demonstrate to other countries in the western hemisphere that if they did not pay their foreign debts the United States would intervene and force them to. Accepting the fiscal convention preempted direct military intervention by the the European states that would have interfered with Dominican sovreignty. It also prevented direct military intervention by the United States. In this sense it allowed the Dominican to avoid a worse fate – invasion. Also, there was implicit coercion involved in American advocacy of the Convention and Dominican acceptance of it. In fact, American forces would invade the Dominican less than one decade later. Finally, President Ramà ³n Cà ¡ceres, eventually assassinated in 1911, was unsure that he could retain power without the support of the United States which was conditional on his acceptance of the

Literature Review About Meter Reading Techniques Computer Science Essay

Literature Review About Meter Reading Techniques Computer Science Essay In this chapter we will explore more about how meter reading is done, the different type of techniques that exist to read meters, and automatic meter reading; specially the use of Bluetooth technology for automatic meter reading. A world wide view will be explored before we look to the context of Mauritius. Meters A meter is a device that can detects and displays the exact quantity of an element, substance or any quantifiable matter, may it be electrons, water, gas, glucose and many others. There are many uses of meters and in many different sectors of our world. For example, in health sector; meters are used to measure the level of glucose in the blood, to measure pulse rate, and many others. The utility sector, like gas, water or electricity companies, uses a very large numbers of meters. These companies have to monitor the usage of the resources used by their customers so that they can be charged for the amount they have used. There are also other meters like: gauss meters, geomagnetic meters, microwave meters, and many more. As we have seen, there are many sectors in which meters are being used; we cannot focus our attention in all of them. So, we will concentrate our effort in the utility sector, more specifically the one for electricity companies. Why this choice? Because Energy sector is a driving force in our world and that many developments and advances are thanks to electricity. So from here on we will focus our attention on that specific domain. Types of meters There are many types of meters depending on the area of use. The main types of electric meters are: Electromechanical Induction Meter (Standard Meter): It is a meter which counts the number of turns an aluminium disc does. The amount of electricity used is directly proportional to the number of revolutions of the aluminium disc. The electricity is measured in kilowatt-hours and the rate of charge remains constant all over the day. These types of meters are commonly used on single phase alternating current supply. Electronic Meters: These meters have an electronic display and make use of wireless technologies like Bluetooth, GSM and GPRS to transfer information about electrical consumption. They have inbuilt automatic sensors which helps to detect electrical energy theft or meter tampering. Prepaid meters: are like the standard meters; the only difference is that, instead getting a bill at the end of the month, it is a pay as you use service. I.e. the consumer pays in advance for the electricity consumption. Smart meter: These meters record the amount of electricity consumption for a certain period of time. The recorded data is then sent to the utility company for monitoring and billing purposes. Smart meters can transfer data from and to the meter, i.e. it is a two way communication. Meter reading Electric meters measure electricity mostly in kilowatt hour (kWh). One kilowatt hour is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3,600,000 joules. The meter reading process is done periodically, so that consumers can be billed for that period of time. There are different methods used by different companies for metering. There are two ways that can be identified. Namely: the traditional way and new techniques. The traditional way, which uses the standard meter, can be described as: The meter reader goes to the consumers place. There, the meter reader reads the current value on the meter and note it down on the bill for the previous electricity consumption period. The bill is then given to the consumer. The meter reader will then enter the current value in the companys system, so that the consumer can be billed for that current period. The new techniques, which uses, electronic and smart meter are as follows: The meter reader makes use of new technologies to read the meter value, and meters have an electronic display. There are many different new techniques used for meter reading, and they will be further elaborated below. Automatic meter reading (AMR) Automatic meter reading (AMR), is the technology where data about consumption and the status of the meter device is collected automatically. The data is sent to a central database for it to be analysed and billing purpose. Meters for water, gas, and electricity can use the AMR technique. With the uses of AMR, there can be one way or two-way communication. In the one way communication, query is done only to know the reading value from the meter. Whereas in the two way communication; functions can also be implemented to the meter. Techniques for automatic meter reading There are several techniques for automatic meter reading; some of them are listed below. Touch Technology In the touch technology, a meter reader have a device, it may be a handheld computer or specialised data collection device. When the meter reader in close range to the meter; the latter press a button. A signal is sent firm the device to the meter and the reading of the meter is saved on the device. That saved data is downloaded to a data collection computer for billing purpose. This technique is also referred as on-site AMR, as the meter reader needs to go on site to read the meter reading. Radio Frequency Network As its name suggest, the network uses radio wave to communicate with the meters. There are automatic reading systems which uses the radio based technology such Wi-Fi, ZigBee, Bluetooth and many others. Some of them are listed below. Handheld: a meter reader collects meter reading from meters which support AMR system. The meter reader carries a portable computer with a radio frequency receiver and transceiver which reads the meter readings value. [2] Mobile: it is also referred to as drive-by is a technique where the meter reading device is installed in a vehicle. The meter reader needs only to drive the vehicle along the path where the meters are found and the meter reading value is read automatically by the device installed in the vehicle. [2] Fixed network: it is a method where there is a network which is installed permanently to read meter reading. The network consists of many repeaters, collectors and a lot of other equipments so that values read are transferred to a central database. This method does not need the intervention of any human to read the metering value. Some time a hybrid AMR system is implemented so that when the fixed network goes down, the mobile system come into action. [2] Assessing the traditional meter reading and AMR The advantage and disadvantage of both traditional meter reading and AMR techniques are listed in the table below. Traditional Meter Reading Advantage Disadvantage Creation of job, as more people are needed to perform meter reading Social contact with consumers There can be error when reading the value. Difficult to detect fraud on meters. Some people consider the meter reader as an intruder in their privacy. Security of the person performing the reading the person may be attacked by dogs Table 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ1: Traditional Meter Reading Automatic meter reading Advantage Disadvantage Enable theft detection. More accurate meter reading. Reduce operating cost. There is no need to enter consumers property (except for exceptional cases). If the system is down, billing will be affected. The use of radio waves can be a source of concern to a minority of people Table 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ2: AMR Existing system using Automatic Meter reading There are many AMR systems implemented in many in different countries and using many of the different techniques listed above. Some of the existing AMR systems are listed: New Mexico Gas Company is using the AMR service. This has greatly helped to improve the working of the company. [4] The Ontario government introduced legislation on Nov. 3, 2005 to start the process of getting smart meters into every home and small business in the province by 2010. [5] Meridian Energy has started replacing traditional electricity meters with new smart electricity meters which will set a new benchmark for electricity retailing in New Zealand [6] Existing system of Bluetooth enable meter reading There are some companies which are using Bluetooth enabled meter for the reading of their meters, and there are some supplies of Bluetooth enabled meters. The topic is further developed below. Existing system Cambridge Consultants has delivered a prototype design of a Bluetooth-based radio module to the leading utility metering company, Actaris. Based on a single-chip Bluetooth device, the module provides new opportunities to drive down the cost of remote metering, allowing meters to be wireless-enabled at very low cost and opening the door to high-integrity consumer-activated schemes. Consumers with Bluetooth mobile phones, laptops or PDAs would have the option of taking meter readings themselves and communicating them to the utility company over the internet or GSM. [7] Bluetooth enabled meters suppliers There are many suppliers of Bluetooth enabled meters. Some of the suppliers are listed below. Landis+Gyr, is a company which design and manufactures electricity meters. This company have also design a Bluetooth reading system where they can read meters using Bluetooth. [8] Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ1: Bluetooth reader [8] Metex Corporation limited is a company which is manufacture meter readers, and the company has meters with Bluetooth technology. These meters can be used in an AMR system. [9] Current situation in Mauritius In Mauritius, we have the Central Electricity Board (CEB), Central Water Authority (CWA) and Waste Water Authority (WMA) as the main utilities companies. All these utilities companies are using the traditional way for their billing purposes. .I.e. a meter reader will go home by home and read their respective standard meter. The CEB is doing research on how to implement automatic meter reading and they have some electronic meters for testing purposes. CEB has also intention to implement prepaid meters. The AMR system on which CEB is experimenting consist of meter which has a modem. Then a communication is set with the modem and concerned data is read. That data is used for the billing purpose. As mentioned, the system is still at a testing phase, so a lot are still need to be done. To be able to implement AMR system all standard meters need to be changed to AMR supported meters, and meter readers need to be trained to be able to use the new system. Bluetooth Technology What is  Bluetooth? Bluetooth  is a wireless technology for short range communications which was developed to replace the cables connecting devices, may it be fixed or portable ones. Such devices are; mobile phones, printers, cameras, desktop computer, and many others. The Bluetooth  technology is a low power, low cost and maintains high levels of security. Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. [10] The Bluetooth Special Interest Group (SIG), an organization of several companies work together to maintain and develop the Bluetooth technology. [10] The name Bluetooth comes from Danish King Harold Bluetooth. He was influential in uniting warring factions in parts of what is now Norway, Sweden and Denmark. [11] Bluetooth technology can withstand interference from wireless technologies which uses the 2.4 GHz spectrum. Adaptive frequency hopping (AFH) of Bluetooth technology detects other devices in the spectrum and avoid the frequency they are using. [11] According to Martin Reynolds, an analyst with Gartner Groups Dataquest, The thing about Bluetooth is that it really will ship in the billions of units once it gains momentum. Its really a multibillion-dollar market. [12] Bluetooth Logo Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ2: Bluetooth logo [13] Bluetooth range Bluetooth radio waves use certain amount of energy and can goes up to a maximum of certain diameter. The table below show Bluetooth class and its limit up to where it can go. Class Power use (mW) Range (approximate) in meters 1 100 100 2 2.5 10 3 1 1 Table 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ3: Bluetooth class range BLUETOOTH Network There are two type of network: Piconet: is made up of one master and one or more slaves but only up to a maximum of seven active slaves at a time. The device initiating the connection automatically becomes the master and is the master of the piconet. Slaves may not communicate directly with each other; they can only communicate with the master and transfer data when they are granted transmission time by the latter. Slaves synchronize their frequency hopping with the master using the masters clock and Bluetooth address. Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ3: Typical piconet [14] Scatternet: Multiple piconets with overlapping coverage areas form a scatternet. Each piconet may have only one master, but slaves may participate in different piconets on a time-division multiplex basis. A device may be a master in one piconet and a slave in another or a slave in more than one piconet. Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ4: Typical scatternet [15] Bluetooth protocol stacks The Bluetooth protocol stack allows Bluetooth devices from different manufactures to work with one another. Some of Bluetooth protocol stacks   LMP (Link Management Protocol); configure and control links to other devices.   L2CAP (Logical Link Control Adaptation Protocol); links upper layer protocols over the Baseband and the passing on of quality of service information. RFCOMM (Cable replacement protocol): protocol provides emulation of serial ports over the L2CAP protocol.   Service Discovery Protocol; provide a way for discovering services provided by or available through a Bluetooth device. It also allows applications to know about the characteristics of the services which are available.   HCI (Host/Controller Interface); access the hardware status and control register. It also provides a command interface to the Link Manager and Baseband Link Controller. Bluetooth radio is a transceiver which transmits and receives modulated Bluetooth radio waves for the devices. Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ5: Bluetooth protocol stacks [15] Bluetooth profiles Bluetooth profiles help two devices which have the same profile to communicate with each other. Each Bluetooth device must support at least one profile. There are a wide range of Bluetooth profiles that explain many different types of applications. Generic Access Profile (GAP): Provides the basis Bluetooth functionality for all profiles. Some of the functionalities are like setting up L2CAP links, handling security modes and discoverable modes. Serial Port Profile (SPP): Provides serial port (RS-232) emulation based on the RFCOMM part of the Bluetooth stack. Dial Up Networking Profile (DUNP): Defines how to a Bluetooth device can be used as a Dial Up Networking gateway FAX Profile: Defines how a Bluetooth device can be used as a FAX gateway Headset Profile: Defines what is required to transfer audio e.g. a wireless Bluetooth headset LAN Access Point Profile: Defines how a Bluetooth device can be used as a LAN access point Generic Object Exchange Profile (GOEP): Provides support for the OBjext EXchange (OBEX) protocol over Bluetooth links Object Push Profile: Defines how to exchange vCard and vCalendar objects, based on the GOEP File Transfer Profile: Defines functionality of how to navigate through folders and copying, deleting or creating a file or folder on a Bluetooth device, based on the GOEP. Figure 2à ¢Ã¢â€š ¬Ã¢â‚¬Ëœ6 : Bluetooth Profiles [16] THE ADVANTAGES OF BLUETOOTH Short transmission range up to a maximum of 100 meters with class 1. Low Power: Bluetooth takes relatively low power, thus it is suitable for devices with restricted battery capacity. Interoperability: as it have standardised protocols. Robustness: capable of operating in an environment strongly where there are many other radio waves Technologies for developing the system There are many phase for the development of a system and there are many tools available for their development. Two categories can be identified for a system; hardware and software. The hardware part is the part that can be hold by hands and move if it is portable. The software part can be seen as the one who make the hardware works correctly. Without the software, the hardware cannot be used fully. Programming language There are a series of programming languages that are available to programmers to code systems. Each programming language has an area of application where it is better. Some of the programming languages are listed below. Java Java is cross platform and GNU General Public License  programming language.

Visual Basic.Net (VB.Net) Visual basic is implemented on .Net framework. VB.Net was designed by Microsoft and it is an object oriented language. Relational Database Management System (RDMS) Some of RDMS are listed below: MySQL MySQL is a relational database management system which is released under the GNU General Public License. It offers multi-user access to databases and it is cross platform software. PostgreSQL PostgreSQL is an object-relational database management system (ORDBMS) and it is released under PostgreSQL License. Thus it can be modified and distributed in any form desired. Web Server A Web server is responsible to process users request and reply back. The replies are mainly HyperText Markup Language (HTML) documents. Web servers are mainly used t host Web sites. Apache HTTP Server Apache HTTP Server is a Web server which is licensed under Apache License 2.0, which means that it is an open source HTTP server. It is platform independent, highly secure and efficient. Internet Information Server (IIS) IIS was created and is owned by Microsoft. There is need to buy it license to use it. Web Development Tools There are many server side scripting languages that are used. Some of them are listed below: PHP PHP (Hypertext Preprocessor) is a general-purpose scripting language that was designed for web development so as to have dynamic web pages. PHP can work on most servers and operating system. ASP.NET ASP.NET allows programmers to build dynamic web pages, web services and web application. It is a web application framework developed and marketed by Microsoft. Hardware Some of the hardware that can be used is listed below.

J2ME is used for the mobile application development as many mobile phones can support java and have an API for Bluetooth. Bluecove API for Bluetooth programming as it is open source and support java. PHP will be used for the web application as it is free and easy to interact with database. MySQL is more suitable for database system as it is free and work well with Web servers. Design The design section gives an overview of the structure of the software and architecture of the system. It also includes the data involved, the interfaces between system components, algorithm and protocol to be used for the system implementation. System Design Issues Several system design issues like performance, quality of service, fault tolerance, and security, which are important in the design of a system, are discussed below. Performance Issues The performance issues are concerned with the limitation of computers in term of processing power and communication capacities. These issues can be described in the followings ways: Responsiveness: It is how fast the system processes given input to give an output. The use of threading allows multiple tasks to process simultaneously. Threads can be used for processor intensive process. Threads can be implemented in Java Environment. Applications running on networks depend greatly on the load and performance of servers and also the network load itself. Server and network load balancing can be used to prevent them from being overloaded. Such technique is beyond the scope of this project. When using the Internet, there is a probability of communication delays and data being corrupted, this beyond of ones control. Throughput: It is of the system corresponds to the amount of data transmitted between the client and server in a given time interval. On a wireless network is takes a long time to establish connection between the server and the client and the latency time of HTTP is significantly high. So, the number of HTTP round trips in the application must be kept to the strict minimum. Robustness Robustness is the ability of the system to operate in the presence of incorrect input or cope with errors when the system is running. Validations check like length check and data type check can be used to prevent wrong input and catch errors where shared resources are being accessed. Interactivity Interaction with the system can be in many different ways. Data or command input to the system will make it produce certain result. Some of the ways that can interact with the system are listed below. The use of graphical user interface (GUI) to facilitate user to communicate with the system. Providing options and menus where possible instead of typing data. Users using the mobile application need to enter data via phone keypad. Use of meaningful icons, so that user can interact quickly with the system. Flexibility The web application can support multiple users at a time and can receive and process multiple requests a time. The system must be able to cope if there is significant increase in the number of users and additional resources can be added if needed to. Portability The mobile application can be run on Java enabled mobiles phones which support MIDP 2.0. The web application can run on multiples types of servers. Limit size of JAR file The mobile application has limited resources to use. So the application is obfuscated to reduce its size. The obfuscation process helps to remove unused classes and libraries. Error, Exception Handling and Fault Tolerance The application should continue to work correctly in presence of software, hardware and network faults. Errors will be caught in try-catch blocks to alert user of the error. Security Security is one of the focal point of a system. There is no system on earth which can be tagged as impenetrable. What can be done is, to make the system less vulnerable to attacks. The system needs to protect data from unauthorized users. The ways to protect the system is listed below. Users need a username and password to be able to access the system. User will be identified and authenticated before they can use the system. The database will be protected with password. Architectural Design In this section, the different components of the system are illustrated and how they interact between them. Overall Architecture The system is made up of three main components: the meter, the mobile application and the server application. The mobile application will be used to read a value via Bluetooth from the meter and will send that value via mobile network operator to the server. The connection between the mobile and the server is done via wireless connection such as GPRS, WAP, EDGE or Wi-Fi. The meter will be a simulated meter on a laptop that will be accessed via Bluetooth by a mobile application. The server will be used to host the web site and connect to the database. That database will be used to store all information needed. The figure below shows the overall architecture.

My Childhood lost ? Essay

I was a happy go lucky six year old boy staying at St. Peter’s orphanage. The orphanage had about 20 children. The living conditions were not anything fancy, but we had no complaints either. I distinctly remember the morning of 1st May, 1820 when a wealthy looking middle aged gentleman came to our orphanage. He pretended to be a nice but lonely guy who wanted to adopt two healthy children between the age group of 6 to 10. He met all the children and finally selected Berley, the eldest in the group, and myself. We were thrilled! I assumed that my life would be a bed of roses from now on. Both Berley and myself bade good bye to our friends and â€Å"home† beaming with hope and dreams of a better life ahead. Our â€Å"not so lucky† friends wished us best of luck with tears in their eyes. Berley and I would now be brothers living with a wealthy man. We entered his large palatial house with trembling legs. Before long we were taken to the backyard, which, unlike the rest of the house, resembled a slum. There we met a few more children who stared at us blankly. They looked ugly, unkempt and had dark circles under their eyes. One of them had an amputated finger. Though their sight made us feel uneasy, we decided to concentrate on our first meal. Both Berley and I were expecting a treat but to our disappointment it was the worst food we had ever eaten. Soon the truth surfaced and we realized that the wealthy gentleman had â€Å"bought us† as slaves to work in a factory where he was an overseer. We were trapped for life†¦Ã¢â‚¬ ¦ The next day started at 4 am. After getting ready we went to a dark and stinking factory where they made cotton. I was assigned to pick up dirty waste material that was being generated almost continuously. After working diligently for almost four hours I felt tired and claustrophobic so I decided go for a stroll and explore the factory with Berley. As we were walking out together, our so called â€Å"father† appeared with a big whip in his hand. Without assigning any reason, he whacked both of us several times. I stupidly sat down on the dusty floor and started howling while Berley ran back to his assignment. The overseer got angrier with me and said, ‘Not happy with one beating, eh? ‘ He gave me two hard shots on my back and harshly told me to go back to work. With big tears and a paining back I returned to complete my job. Thereafter I was then forced to go under a large machine & continue the cleaning. By the time I finished I had blood on my fingers due to a minor accident. Berley, my only friend, rushed to comfort me while I was crying For years thereafter this routine continued. Without Berley by my side I would not have managed to cope. However, we both often wondered that if this was indeed industrial revolution for a better future, someone, somewhere had made a mistake†¦.

Effects of Attitudes and Prejudices on People Who Use Services Essay Example

Effects of Attitudes and Prejudices on People Who Use Services Essay Example Effects of Attitudes and Prejudices on People Who Use Services Essay Effects of Attitudes and Prejudices on People Who Use Services Essay Peoples attitudes and beliefs can be discriminating towards different groups of people. Discrimination can be defined as the negative treatment taken towards or against a person of a certain group which can be on the basis of sex, religion, class, gender, race, marital status, beliefs, disability, and sexual orientation. This is known as direct discrimination; for example, a female working in a male dominated environment is overlooked for a job promotion because of her gender. In contrast, indirect discrimination occurs when there are rules, regulations or procedures in place that have a discriminatory effect on certain groups of people. This is a less obvious form of discrimination. For example, a refuge which is for women fleeing domestic violence may choose to only employ female staff due to the sensitive nature of the work. Attitudes and prejudices can affect professionals and services users. For example, care workers may be quick to make assumptions about the people they are caring for. It is important in any caring tasks that the views and feelings are considered continuously. That is, the carer should not stereotype people they are working with into one client group. For example, that all older people have difficulties with their memory and assume because they cannot remember, they cannot express their wishes. Similarly, misjudgements should not be made about people because of the way they look. For example, if a person is in a wheelchair, it cannot be assumed that they are unable to participate in sports or that they dont enjoy playing sports. Stereotyping is harmful when it becomes damaging to the other person. It is important that all care workers who work in health and social care settings do not hold prejudices or negative attitudes.

Identitys Role in Internal Politics of Eastern Europe Countries in the Essay

Identitys Role in Internal Politics of Eastern Europe Countries in the Context of Globalisation - Essay Example Globalisation is perceived differently by different individuals with some believing that it presents new opportunities while others see inequality, and hindrance of national sovereignty. In Eastern Europe, new countries have emerged from the collapse of communism governments that is the Soviet Union and the Yogoslavia, therefore developing new political identities (Genov, 2010). Countries like Poland have emerged from decolonisation hence acquiring different political systems from those of their colonisers. Most of the Eastern Europe countries have originated from authoritarian regimes, which had their identities repressed. Therefore, Eastern Europe countries engage in politics and economic systems that are distant from their colonisers, even going to the extent of changing their entire political systems. Lawmakers ensure that laws match the citizens’ sense of national identity hence satisfying their people’s roles, goals, and values (Schneider, 2010: 931). This paper w ill examine the role of identity in internal politics of Eastern Europe countries in the context of globalisation. Eastern Europe is a place that is diverse historically, culturally and geographically. The people living in Eastern Europe are of different ethnicities where they even speak different Indo-European languages. Eastern Europe is made up of four sub regions. There is the Baltics comprising of countries such as, Estonia, Montenegro, Serbia, Lithuania, and Latvia. The second sub region is East Central Europe comprising of countries like; Slovakia, Czech Republic, Poland, Hungary and Slovenia. The third sub region is Eastern Europe with countries such as, Moldova, Belarus and Russia. The fourth sub region is the Balkans or Southern East Europe with countries like Macedonia Bulgaria, Albania, Croatia, Herzegovina, Ukraine, Romania, and Bosnia. Those countries that are adjacent to Western Europe and centrally placed have adopted similar identities and most have joined the Europ ean Union, therefore, embracing globalisation (Cernat and Murrell, 2002:119). Other Eastern Europe countries that are far placed do not have shared identities with Europe and with the different ethnicity, religions, and political issues, many are considered volatile. Globalisation is defined as a process requiring the reduction of territorial boundaries so as to allow interactive and interdependent worldwide forms of to spread. Globalisation brings about the dissemination and spread of culture, politics, and economy from particular locations to worldwide magnitude. In addition to free movement of cultural values, money, people, and ideas, globalisation calls for mutually beneficial relations (Martel, 2009:461). Its dominant processes of regionalisation (Cernat and Murrell, 2002:119). Identity, whether cultural or national, can influence politics in that lawmakers will attempt to develop policies that will represent the values of its citizens. Policymakers will strive to create forei gn policy laws that will ensure the country’s sovereignty remains strong even among regional economic allies. A country’s national identity is not set at a certain level; therefore, adjustments can be made, allowing the citizens to adopt new interests and values. National identity is simply an illusion that people from one country or region can have about who they are. As globalisation sets in, some national identities evolve and a global perspective is adopted. Politicians sometimes act to serve their best interests of retaining power, when they draft laws that do not allow easy integration or cohesion between a nation and other foreign countries. They usually view integration as a threat, looking to reduce their power. However, globalisation is
