Thevenins Theorem La Report, free essay sample

Calculator RTH as follows RTH = VTH/ ISC Method 2: (By measuring the equivalent resistance) Remove all sources from the circuit, i. e. replace all voltage sources with a short-circuit and current sources with an open-circuit. Then with the help of a multimeter find the resistance between the points ‘a’ and ‘b’, denoted by Req. RTH = Req Method 3: (By applying known voltage and measuring source current). We can also find RTH by applying a known voltage to the circuit between points ‘a’ and ‘b’, then measuring the current from the voltage source. Suppose 1 Vdc is applied as the test voltage then, RTH = Vtest / I 4. Method 4: (By inserting two different resistors and measuring current) There is another method to find the value of RTH, by inserting two different loads between points ‘a’ and ‘b’ i. e. insert resistors R1 and then R2 one by one and write expression for the current through that particular resistor as given below, Current through the resistor R1 :- I1 = VTH / (RTH + R1) Current through the resistor R1 :- I2 = VTH / (RTH + R2) Simultaneously solving these equations will give the value of RTH.

Our aim was to determine the current through and the voltage across the 1k? resistance R1 connected between the two nodes A and B. We followed the following procedure to validate the Thevenin’s theorem. Finding VTH: 1. We removed the resistor R1 from the circuit on breadboard. 2. We then determined the open-circuit voltage (voltage between points A and B i. e. VAB) using a voltmeter. This is the required Thevenin voltage VTH. We recorded this value in Table. Finding RTH: 1. We determined RTH by method A. Further connected an ammeter between load points A and B to measure the short-circuit current ISC. Found the value by RTH = VTH / ISC 2. We then determined RTH by method B. Replaced the voltage sources with short-circuits. Then using an ohmmeter, we found the equivalent resistance between load points A and B. This is RTH. 3. We also determine RTH by method C by Applying a known DC voltage (1 V) between points A and B. Then using an ammeter, we found the current through the test voltage source. We found RTH by: RTH = Vtest / I 4.

analysis of the song Scarecrow essays

analysis of the song Scarecrow essays The Christian music industry is renowned for its many deep, thought provoking songs, but there is none whose lyrics capture my mind like the song Scarecrow, written and composed by the band Skillet. This song is a reflection of the writers perspective of his life as a scarecrow. The artist proposes that we as Christians need to surrender everything to Christ in order to gain a meaningful relationship with Him. The chorus is divided into three different sections, each showing the three essential elements pertaining to our walk with God. The first concentrates on the knowledge part of a persons relationship with God. The second entails the love and emotion that is involved. The last focuses on the servant aspect in our attempt to please God. The comparison of a scarecrow to the life of a human being seeking Christ may seem far-fetched to begin with, but careful evaluation of the wording in this song has shown many parallels. The first part of the verse refers the guilt and shame the scarecrow is dealing with. He feels alone in the world and is shameful of his dirty clothes which represent the sin in his unworthy life. This seems like the ideal analogy for the aimless, consumer driven lives of many lukewarm Christians in todays society. The distractions of life keep getting in the way of truly focusing on God, bringing about a sense of shame and worthlessness. The scarecrow, Safe enough to not let go, seems to have a sense of security in the known that prohibits him from letting go of everything and letting God take over. He is comfortable where he is and does not want to risk change. He also is fearful of the unknown as shown in the text, Scared enough to not release. He is not willing to sacrifice the safety of everything he knows to be true to venture into the unfamiliar. In the next line Open up to drink the wind, the &q...

Toyota Australia to UAE - Essay Example The popularity of the Toyota and its reputation has been considered in dealing with the analysis. Selection of areas were highlighted which could provide added benefit to the export of the business. The underlying risk associated with the entry of foreign markets was also studied in detail. The market of UAE have been found to be promising for the Australian export market and owing to the benefits the market provides Toyota should not resist its temptation to test its fortune in the market. An added advantage which the market of UAE provides is in the low price of diesels, which generally increases the sale of cars. Other than the general market analysis a study of the associated service has been done to find out whether any obstacles lie in the smooth running of the business. 7. Macro-environmental analysis of UAE 7.1 Political and Legal Environment of UAE: The government of UAE is the combination of seven emirates which is ruled by the president. The government of UAE is flexible r elating to the investment from the foreign countries. It promotes and encourages foreign countries to enter their region and carry out business. Despite the nation being the combination of seven different emirates but there exist federalism in the UAE companies law and is applicable throughout. The UAE free zone offers 100%foreign ownership and tax exemptions to companies operating over a period of 15-50 years (United Arab Emirates UAE tax rates, n.d). So it is quite encouraging for the companies to invest in UAE. Owing to such favorable factors the foreign investment in UAE accounted to108billion dollar in 2011. (FDI in UAE, 2008,) 7.2 Economic Environment of UAE: The economic condition in UAE is always on a high and in recent times it is expected to grow at a rate of 3-3.5% in 2011. UAE’s rising economy can be contributed to the export of oil, which over the years have gained considerable amount of revenue for the country. It significantly rose to 30% and caused earnings of 74 billion dollars (UAE oil income up 30% in 2010, 2011). It happens to rise at a considerable rate every year. The employment rate in UAE is considerably high as the foreign companies are obliged to recruit local people. Out of approximately 2 million populations in the emirate a staggering 86.6% of them are economically active.

Due 1 aug - Assignment Example We shall also discuss some diseases or conditions which women are likely to have due to this process. According to Fox – Spencer and Brown (2006), menopause is the point when a woman has her last period which happens when her  ovaries  stop releasing eggs, and for some women, it happens all at once but for many women, it is a gradual process. If a woman has not had a period in more than a year, is not pregnant, or does not have another illness, she may have most likely reached menopause and this typically, this happens when the woman is in her fifties. Planned Parenthood, in their website state that perimenopause is the gradual change that leads to menopause which usually happens between the ages of 45 and 55 but it is not unknown to begin as early as 40, a time when menstrual periods usually become less predictable and they may become more or less frequent or may be heavier or lighter. Women who smoke have a higher possibility of going into perimenopause earlier than those women who do not smoke. Perimenopause is a process that can last for few months or can go on for up to 12 years depending on the physiological make up of the woman involved. If a woman has not had a period for more than a year or two, then this marks the end of the perimenopausal stage and the beginning of menopause. Surgical menopause occurs with the removal of both ovaries in women who have yet to undergo menopause and this induces menopause because they suddenly experience the symptoms of menopause without the normal gradual changes that occur. Women with surgical menopause experience the following changes: hot flashes; sweating at night; the drying of the vagina; heart palpitations; frequent mood swings; unexplained depression; constant fatigue; and some changes in their sexual desire. Stress menopause is caused by the constant stress experienced by a woman on many occasions

Individual Letter Element Essay Example | Topics and Well Written Essays - 750 words

Individual Letter Element - Essay Example In order to top the elite clubs in England and Europe, there exist a number of drivers from the external environment of the club that could be significant in the evolution: international fan base, online merchandise and club marketing, and the club’s loyal owners. Being a football franchise, Arsenal FC greatly relies on the support of fans. Arsenal FC has a huge fan base on the international scene. However, there are millions of unhooked fans that could provide a perfect customer base for the clubs merchandise, assets that collect about 11% of the club’s revenue. Revenue is bound to grow and so is the club’s superiority given the influence that fans usually have on the players. With a huge and loyal fan base, players are likely to work extra hard to avoid being letdowns. Arsenal FC has potential to attract more fans given its current numbers, with statistics showing that Nigeria alone has more fans of Arsenal than the total number of Arsenal fans in the UK alone. Additional PESTEL analysis factors will emphasize the club’s ability to achieve this. The internet has revolutionized into one of the biggest sole market place globally through ecommerce. Online market force opportunity for Arsenal is another key driver that could change the fortunes of its revenues and increase the ability of its fans in getting its merchandise. The current online statistics stand at over 50 million subscribers to its Facebook and twitter page, site, and its online store. The arsenal marketing outfit needs to focus more on online marketing and strive to implement the stalled Click and Collect service. The last key factor that puts Arsenal FC at a position of extensive growth and change is its ownership team that is entirely committed to the core values that run the club. The club has the ability to maintain this by avoiding any frequent change of management witnessed in other major clubs in the country. The above key drivers for change were determined using a framework of PESTEL that ensured viability and realism. The Political factor (P) provides favorable environment by letting football franchises operate independently thus independence. With independence, the club ownership of Arsenal FC is liberal enough to do anything under their sleeve that would improve the club’s fortunes. The steady revenue income for the club is a key Economic factor (E) to count on in ensuring enough capital in online marketing and increasing the international fan base through numerous promotions. The stable economic situation globally has enabled emergence of a population class that is stable enough to involve in fun activities such as football. This is a Social factor (S) that ensures availability of potential fans for the club. Literacy level in IT matters in the society have increased, facilitating a possibility of high access to online material, a strategy Arsenal intends to market itself. Technology (T) has ensured the availability of internet and numerous smart devices that would enable easy implementation of Arsenal’s online marketing strategies. In implementing all the key drivers, care was taken not to violate any Environmental factors (E) thus avoiding pollutants of any kind. For the Legal factors (L) Arsenal’s self-sustaining business model of operation shield’s it from legal confrontations by not infringing any competition law that governs English football. Arsenal has a number of strengths and an equal share of weaknesses

Development of College Announcement Notification System

Development of College Announcement Notification System Chapter 1: Introduction Introduction This project proposal is created to propose an IT solution to the student of Sunway University. The main point that the author want to highlight is regarding the efficiencies for student in Sunway University. An example, inefficiencies that occur in posting the announcement that is post on the website or in the notice board, it is hard to inform to the student and also the staff may also forget to post the announcement that will inconvenient for the student itself. In order to solve those problems, the author proposed to create a website as a third party for the staff to post the announcement. The author feel that only a website is very simple and common nowadays, so to improve the effectiveness and give more efficiency, a SMS (Short Messaging Service) feature is added to the system. Every announcement is posted by the SCT Staffs in the website, a SMS notification will be sent to the student that already registered to the website. The content of the SMS just a brief notification abou t the title of the event, venue and time, for more brief detail the students can refer to the website. Other way to notify the students is used Email as an instant notifier, but consider using email as an instant notifier is not really effective because students didnt open their email every day but using the SMS as the instant notifier to notify the students are more effective because most of the student is own and bring their own cell phone, therefore the MS as an instant notifier is more appropriate. Since the advancement of the technology nowadays, using this system will help in reduce the paper usage. Project Objective To give efficiencies for staff of Sunway University who want to post announcement. To use SMS as an instant notifier, for example every announcement post on the website the student will receive a SMS about the annoncement. In long term of view, this system will help in notify student about things that happen in college. Project Scope To become the most useful media for announcement notification. When the system is run it involves the Sunway University students and staffs that want to use the service. The user of the system should be students of Sunway University and staffs. All users that want to use the system have to become member. Methodology Methodology is a formalized approach to implement the SDLC (System Development Life Cycle). There are many different systems development methodologies, and each one is unique based on the order and focus it places on each SDLC phase. Some methodologies are formal standards used y government agencies, while others have been developed by consulting firms to sell to client. Many organizations have internal methodologies that have been honed over the years, and they explain exactly how each phase of the SDLC is to be performed in that company. There are many ways to categorize methodologies. One way is looking at whether they focus on business process or the data that support the business. There are three types of system development methodologies, it is called Structured Design, RAD (Rapid Application Development), and Agile Development. Types of Software Development Methodologies Structured Design This is the first type of system development, it is introduced in 1980s. This methodology adopts the formal step by step approach to the SDLC, it moves logically from one phase to another phase. Waterfall Model This is the original structured design of methodology, with this methodology, the analyst and users proceed in sequence from one phase to the next phase. The key deliverables for each phase are typically very long and are presented to the project sponsor for approval as the project moves from phase to phase. This methodology is referred to as waterfall development because it moves forward from phase to phase in the same manner as a waterfall. Advantages of using waterfall model: It identifies system requirements long before programming begins It minimizes changes to the requirements as the project proceeds. Disadvantages of using waterfall model: The design must be completely specified before programming begins This model required significant rework, if there is a changes in the business environment, in order to going back to the initial phase need to go through each of the subsequent phase in return. Parallel Development This model of methodology attempts to address the problem of long delay between analysis phase and the delivery of the system. Instead of doing design and implementation in sequence, it performs a general design for the whole system and then divides the project into a series of distinct subprojects that can be designed and implemented in parallel. Once all subprojects are complete, there is a final integration of the separate pieces, and the system is delivered. Advantage of using parallel model: It can reduce the schedule time to deliver a system There is less chance of changes in the business environment causing rework Disadvantage of using parallel model: The approach still suffers from problem caused by paper documents It adds new problem, sometimes subprojects arent completely independent; design decisions made in one subproject may affect another subprojects Phased Development In this model, the overall system is divided into a series of version that are developed sequentially. The analysis phase identifies the overall system concept, and the project team, users and system sponsors then categorize the requirement into a series of version. Advantage of using phased model: Quickly getting a useful system into the hands of the users While the system does not perform all the functions the users need at first, it does begin to provide business value sooner than if the system were delivered after completion, as is the case with waterfall or parallel methodology. Disadvantage of using phased model: The users begin to work with the systems that are intentionally incomplete, it is critical to identify the most important and useful feature and include them in the first version, while managing users expectation along the way. Prototyping In this model, it performs the analysis, design and implementation phases concurrently, and all the three phases are performed repeatedly in a cycle until the system is completed. In this methodology, the basics of analysis and design are performed, and work immediately begins on a system prototype, a â€Å"quick and dirty† program that provides a minimal amount of features. Advantage of using prototyping model: It is very quickly provides a system for the users to interact with, even it is not ready for widespread organizational use at first. Reassure the users that the project team is working on the system Helps to more quickly refine real requirements rather than attempting to understand a system specification on paper, the user can interact with the prototype to better understand what it can do and cannot do. Disadvantage of using prototyping model: Its fast paced system releases challenge attempts to conduct careful, methodical analysis. This can cause problems in the development of complex systems because fundamental issues and problems are not recognized until well into the development process. Software Development Methodology Comparison After do research about the types of methodology that is appropriate to be used into the project. The author compared the 4 types of methodology that is compatible with the current development. The following table is the result of using the described methodology to the project. System Characteristic Waterfall Parallel Phased Prototyping Unclear User Requirement Poor Poor Good Excellent Unfamiliar Technology Poor Poor Good Poor Complexity of the System Good Good Good Poor Reliability of the System Good Good Good Poor Short Time Schedule Poor Good Excellent Excellent Schedule Visibility Poor Poor Excellent Excellent Table 1 Methodology Comparison Selecting the appropriate Methodology According to the project objective that the author proposed, author analyze each methodology that is already been researched. The author decides to use the Phased Methodology. The main reason on why the author uses this methodology is because the author would develop this system all by himself and the project will be easier to be built phase by phase. Other considerations in choosing this model are: User Requirement: the requirement of the system is clear, which is to address the problem of inefficiency and ineffectiveness of conventional way in notify the student for announcement. Familiarity with Technology: for designing the website, PHP, VB.Net language technology is going to be used, since it is still in area of the author expertise. System Complexity: the complexity of this project is at medium level, since the author familiar with the technology used in the project so it is not really difficult. However the author still need to do research on certain area of technology, for this case the knowledge of SMS gateway, and how to integrate the web based system with the SMS gateway. Duration: the duration of developing the project is approximately 4 months in order to fully complete the project. Development Method: it is a web based application that is built using the PHP, and VB.NET as the programming language. Area of Research Certain areas that we research for this project are: How to create easy and manageable database system? What is SMS (Short Message Service) portal and SMS (Short Message Service) gateway? How to integrate web based system with SMS portal? How to create easy and manageable database system? This part is one of the crucial parts in order to make a good web based application system. Therefore, creating an easy and manageable database system is really important. The database system that the author used to manage the College Announcement System web based application is MySQL. Several reasons become the consideration of choosing the MySQL software are, first reason is because the main programming language system that the author built is using the PHP technology, and PHP language has an integrated connector that able to connect it to SQL. Second reason, MySQL is open source software so it is free for download, it is will help in determining the project cost development. There is other software which is better than MySQL but looked back at the scope of the project; this is just an undergraduate project, then the author decides that using MySQL software is a wiser choice. The third reason, the author already took the MySQL subject during the study in Sunway University College, which is still in the author expertise. However, if this system wants to be implemented into the real organization, further study to create easy and manageable design is needed. When the project is already on the run, this would be very beneficial in doing maintenance of the application system. How to integrate the Web based System with SMS portal? As most people known that SMS is the most famous service that a mobile phone give. It is a service where the users able to send short text message from a mobile phone to another mobile phone. Basically the SMS would not work with just the mobile phone itself, it I because the Mobile Phone Network Operator that give the service so the SMS can be delivered to the recipient by the help of the mobile phone device as the medium to type the message. The SMS can travel all the way from the sender device to the recipient device must go through a pathway through a network called SMSC (Short Message Service Centre). SMSC works as a hardware that stores the SMS that is sent from a mobile phone then forward it again to the recipient. From the early of 1990s, the era when the first SMS is sent through the network using the mobile phone device. Nowadays with the advancement of the technology, SMS not only can be done through using mobile phone but can be integrated in other application such as web based application system, using the SMS gateway technology. However, the SMS that is sent still have to go through SMSC, which is still needed to use the SIM Card that is given by the mobile network operator. SMS gateway act as a bridge the platform that cannot use the mobile phone SIM Card to use the mobile service by using the GSM modem, in this case the mobile service is to send the SMS. The mobile SIM Card will be inserted into the GSM modem. GSM modem will act as the third party to connect to the SMSC. The web based application store the message that will be sent into the database, and the GSM will retrieve the data from the database and ready to send the SMS to the destination number. The basic function of SMS and e mail is the same, for email the sender need to enter the destination email and for SMS the sender need to enter the destination phone number. The difference is why SMS is more popular than email is because it is mobile and user can send and receive SMS wherever they are. The mobile advantage of using SMS is the reason that makes the author choose the SMS application system to be added into the College Announcement Notification system instead of using email. Another reason the author choose to use SMS is because most of the students in Sunway didnt have mobile phone that can handles in receiving and sending email, but most of the students have mobile phone that enable them to send and receive SMS. Therefore, using the SMS as additional software into College Announcement Notification system is the best choice, and the author also learn to use the GSM modem and the implementation of it into the system. Software / Hardware Requirements In order to make this project successful there are some hardware and software which is required to use in order to complete the project are: Software and Hardware requirement to develop the system. Software: SQL YOG: is the database software that the author chose to be implemented inside the College Announcement Notification system. SQL Yog had the user friendly interface and it is open source software. XAMPP: this software is applied as the localhost to compile the web based application. Adobe Dreamweaver: is the software that makes it easier to edit the coding for PHP, JAVA. Hardware: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD Software and Hardware Requirement to run the system. User Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD User Side Software Requirement: Web browser: Mozilla Firefox, IE, Google Chrome, etc Server Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD GSM Modem Server Side Software Requirement: Adobe Dreamweaver SQL Yog Web Browser: Mozilla Firefox, IE, Google Chrome, etc XAMPP Server side software requirement is needed to do the regular maintenance on the system. The development software might be needed to fix error that might be occurred when the system on the run. Chapter 2: Literature Review Literature Review Literature Review is a critical look at the existing research that is significant to the work that is currently undergo. The author currently did a project; College Announcement Notification System is the project. College Announcement Notification System is a web based application system, which is proposed as a solution to Sunway University College regarding the poor information flow in Sunway University College especially School of Computer Technology. The author chose to propose the solution only to School of Computer Technology because of the course that currently taken is under it. College Announcement Notification System is a web based application, it is hoped the system would work perfectly and increasing the information flow within School of Computer Technology (SCT). The users of the system able to access the College Announcement Notification System via laptop or PC, as long there is an internet connection. The author think if it just a normal website, there is no uniqueness that makes my project different than the others. After doing research, the author decided to add the SMS feature as the instant notification system. Integrate the system with SMS feature; means need to deal with SMS gateway. The author aware that using the SMS feature is almost the same like adding the Email as the instant notification where the system is able to send automatically the posted announcement that is already posted in the website. Email is an electronic mail that worked same like a normal mail, where the users need to write the content of the letter, after that the address of the recipient is a must for the users to add. Email enables users to send and receive electronically over the internet. SMS and Email basically is the same, it contains text and to send it need to know the exact recipient email address for email and phone number for SMS. There are many email server company that is give services for the users to send and receive email such as Hotmail, Yahoo Mail, Go ogle Mail, etc. There is also an application that handles email such as Microsoft Outlook. Some advantages that email could give are emails is free for users to use like send and receive mail, it can contains richer message contents than the conventional mail did. However from the advantages that an email, there are also a few disadvantages of emails. With the advancement of the technology nowadays, the previous email only can sent the words but nowadays, users can sent not only words but can attach richer media such as picture, video, file, etc. This advantages of email were misused by some people, it enable them to send virus, malicious software, spam that can harm the recipients PC or laptop. In order to overcome this security issue, the email provider companies try many ways to increase the security but the spammer can overcome the security and still sent the spam email that may contain virus and malicious software. Using the email as an instant notification to the College Announcement Notification System is a good choice but users may not open their own email daily, usually users open their email whenever the feel like to open it. Therefore, the author proposed to use the SMS system as the instant notification. There are few reasons that become the considerations of choosing SMS to be implemented. First reason, the project is a notification system so SMS is the best choice because after the sender sent it then the recipients received it in instant. Second reason, if using email the recipients of the email need to open their own laptop or PC, and then open the email service web page, it will takes time and not instant. Most of the students nowadays had their own mobile phone and they carry their mobile phone everywhere they go, so it is one of the reason why the author choose to use SMS as an instant notification. Mobile phone user aware that open a SMS is faster than open an Email. Nowadays, ma ny mobile phone producers now produced a new mobile phone that can handles in send or receive an email. However mobile phone that can handles send and receive email is still too expensive for the most of the mobile phone users only a few that can afford that. But if the SMS only, most of the mobile phone users able to send and receive that because it is the basic function that the mobile phone offer. SMS (Short Messaging Service) As most people known, SMS is a protocol used in communication that gives way to exchange of short message from one mobile phone to another mobile phone (tech-faq.com, 2009). Nowadays mobile phone takes an important part because it provides connections to the others that in the past impossible to do. The main usage of the mobile phone is to enable users to make a phone call wherever and whenever they are, beside used to call others; other main function of mobile phone that is growing rapidly is the usage of SMS service. SMS stands for Short Message Service. It is a technology that enables the sending and receiving of messages between mobile phones. SMS first appeared in Europe in 1992. It was included in the GSM (Global System for Mobile Communications) standards right at the beginning. Later it was ported to wireless technologies like CDMA and TDMA. The GSM and SMS standards were originally developed by 3GPP (Third Generation Partnership Project) is responsible for the development and maintenance of the GSM and SMS standards. As suggested by the name Short Message Service, the data that can be held by an SMS message is very limited. One SMS message can contain at most 140 bytes (1120 bits) of data, so one SMS message can contain up to: 160 characters if 7-bit character encoding is used. (7-bit character encoding is suitable for encoding Latin characters like English alphabets.) 70 characters if 16-bit Unicode UCS2 character encoding is used. (SMS text messages containing non-Latin characters like Chinese characters should use 16-bit character encoding.) SMS text messaging supports languages internationally. It works fine with all languages supported by Unicode, including Arabic, Chinese, Japanese and Korean. Besides text, SMS messages can also carry binary data. It is possible to send ringtones, pictures, operator logos, wallpapers, animations, business cards (e.g. VCards) and WAP configurations to a mobile phone with SMS messages. One major advantage of SMS is that it is supported by 100% GSM mobile phones. Almost all subscription plans provided by wireless carriers include inexpensive SMS messaging service. Unlike SMS, mobile technologies such as WAP and mobile Java are not supported on many old mobile phone models. (developershome.com, 2008) Usage of SMS As the mobile voice communication market approaches saturation, carriers are focusing on messaging as crucial value -added service to garner more mobile subscribers and generate greater market revenue. Specifically, SMS (Short Messaging Service) is emerging as one of the most important asynchronous communication that carriers provide. It is projected that in 2009 U.S subscribers will send over 126 billion messages via their mobile phone device, generating $8.6 billion revenues (Deng, Sun, Turner, Prince, 2008). Nowadays, people are presented with a wide variety of communication media such as email, instant messaging (IM), etc. To date, most researchers have focused on the use of SMS by teenager and young adult. Recently as SMS become the needs in our daily lives, older people also recognized the convenience of using SMS. It has been reported that over 74% of the mobile phone users worldwide is using SMS text messaging (Deng, Sun, Turner, Prince, 2008). How does the SMS works? Even if you are not talking on your cell phone, your phone is constantly sending and receiving information. It is talking to its cell phone tower over a pathway called acontrol channel. The reason for this chatter is so that the cell phone system knows which cell your phone is in, and so that your phone can change cells as you move around. Every so often, your phone and the tower will exchange a packetof data that lets both of them know that everything is OK. Your phone also uses the control channel for call setup. When someone tries to call you, the tower sends your phone a message over the control channel that tells your phone to play itsringtone. The tower also gives your phone a pair of voice channel frequencies to use for the call. The control channel also provides the pathway for SMS messages. When a friend sends you an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to your phone as a little packet of data on the control channel. In the same way, when you send a message, your phone sends it to the tower on the control channel and it goes from the tower to the SMSC and from there to its destination. (howstuffworks.com, 2005) The SME (Short Message Entity), which is typically a mobile phone or a GSM modem, can be located in the fixed network or a mobile station, receives and sends short messages. The SME was sent to the SMSC.TheSMSC (Short Message Service Center)is the entity which does the job of store and forward of messages to and from the mobile station. After receiving the SME, then SMSC sent the SME to the SMS GMSC. TheSMS GMSC(SMS gateway MSC (Mobile Switching Center)) is a gateway so that MSC that can also receive short messages. The gateway MSC is a mobile networks point of contact with other networks. On receiving the short message from the short message center, GMSC uses the SS7 network to interrogate the current position of the mobile station form the HLR, the home location register. HLRis the main database in a mobile network. It holds information of the subscription profile of the mobile and also about the routing information for the subscriber, i.e. the area (covered by a MSC) where the mobile is currently situated. The GMSC is thus able to pass on the message to the correct MSC. MSC(Mobile Switching Center) is the entity in a GSM network which does the job of switching connections between mobile stations or between mobile stations and the fixed network. AVLR(Visitor Location Register) corresponds to each MSC and contains temporary information about the mobile, information like mobile identification and the cell (or a group of cells) where the mobile is currently situated. Using information from the VLR the MSC is able to switch the information (short message) to the corresponding BSS (Base Station System, BSC + BTSs), which transmits the short message to the mobile. The BSS consists of transceivers, which send and receive information over the air interface, to and from the mobile station. This information is passed over the signaling channels so the mobile can receive messages even if a voice or data call is going on. (logixmobile.com) How to send SMS using a computer? After done some research about how the SMS works, there are several ways in sending SMS using computer, they are (developershome.com, 2008): Connect a mobile phone or GSM/GPRS modem to a computer / PC. Then use the computer / PC and VB commands to instruct the mobile phone or GSM/GPRS modem to send SMS message. Connect the computer / PC to the SMS center (SMSC) or SMS gateway of a wireless carrier or SMS service provider. Then send SMS messages using a protocol / interface supported by the SMSC or SMS gateway. Connection between mobile phone or GSM/GPRS modem to computer using VB command for sent SMS A GSM/GPRS modem is a wireless modem that works with GSM/GPRS wireless networks. A wireless modem is similar to a dial-up modem. The main difference is that a wireless modem transmits data through a wireless network whereas a dial-up modem transmits data through a copper telephone line. To send SMS messages, first place a valid SIM card from a wireless carrier into a mobile phone or GSM/GPRS modem, which is then connected to a computer. There are several ways to connect a mobile phone or GSM/GPRS modem to a computer. For example, they can be connected through a serial cable, a USB cable, a Bluetooth link or an infrared link. The actual way to use depends on the capability of the mobile phone or GSM/GPRS modem. After connecting a mobile phone or GSM/GPRS modem to a computer, you can control the mobile phone or GSM/GPRS modem by sending instructions to it. The instructions used for controlling the mobile phone or GSM/GPRS modem are called by using VB commands. The above figure showed the process of sending SMS using the VB application. In this case, the system that the author developed is using PHP that act as the third party to store the announcement data inside the database. After finish with the stored announcement, VB application is used to instruct the GSM modem to send SMS. As shown in the figure above, VB application will retrieve the stored data that will be sent as SMS. Then after retrieving the data, it will be sent to through SMS gateway until it arrived in the hand of the recipient. One of the benefits from using the VB application to send SMS is users will have a very reliable notification system, because before sending SMS intended recipient can be configured so it is received at the intended recipient. Using a mobile phone or GSM/GPRS modem to send SMS messages has a major drawback, which is the SMS sending rate is too low. Only 6-10 SMS messages can be sent per minute (when the SMS over GSM mode is used). The performance is not affected by the connection between the computer and the mobile phone or GSM/GPRS modem (i.e. the SMS sending rate is about the same no matter the mobile phone or GSM/GPRS modem is connected to the computer through a serial cable, USB cable, Bluetooth link or infrared link) and does not depend on whether a mobile phone or GSM/GPRS modem is used (i.e. the SMS sending rate is about the same no matter a mobile phone or a GSM/GPRS modem is used). The determining factor for the SMS sending rate is the wireless network. (developershome.com, 2008) Send SMS from Computer through SMS Gateway The way for sending SMS messages from a computer through a mobile phone or GSM/GPRS modem has a major limitation, which is the SMS sending rate is too low. If you need a high SMS sending rate, obtaining a direct connection to the SMS center (SMSC) or SMS gateway of a wireless carrier is necessary. It can be difficult for small businesses or individual application developers to obtain a direct connection to the SMSC or SMS gateway of a wireless carrier since a wireless carrier may only provide such service to those who have huge SMS traffic. Buying SMS messages in bulk means the total fee will be very high (although the fee per SMS message will be low). (deve Development of College Announcement Notification System Development of College Announcement Notification System Chapter 1: Introduction Introduction This project proposal is created to propose an IT solution to the student of Sunway University. The main point that the author want to highlight is regarding the efficiencies for student in Sunway University. An example, inefficiencies that occur in posting the announcement that is post on the website or in the notice board, it is hard to inform to the student and also the staff may also forget to post the announcement that will inconvenient for the student itself. In order to solve those problems, the author proposed to create a website as a third party for the staff to post the announcement. The author feel that only a website is very simple and common nowadays, so to improve the effectiveness and give more efficiency, a SMS (Short Messaging Service) feature is added to the system. Every announcement is posted by the SCT Staffs in the website, a SMS notification will be sent to the student that already registered to the website. The content of the SMS just a brief notification abou t the title of the event, venue and time, for more brief detail the students can refer to the website. Other way to notify the students is used Email as an instant notifier, but consider using email as an instant notifier is not really effective because students didnt open their email every day but using the SMS as the instant notifier to notify the students are more effective because most of the student is own and bring their own cell phone, therefore the MS as an instant notifier is more appropriate. Since the advancement of the technology nowadays, using this system will help in reduce the paper usage. Project Objective To give efficiencies for staff of Sunway University who want to post announcement. To use SMS as an instant notifier, for example every announcement post on the website the student will receive a SMS about the annoncement. In long term of view, this system will help in notify student about things that happen in college. Project Scope To become the most useful media for announcement notification. When the system is run it involves the Sunway University students and staffs that want to use the service. The user of the system should be students of Sunway University and staffs. All users that want to use the system have to become member. Methodology Methodology is a formalized approach to implement the SDLC (System Development Life Cycle). There are many different systems development methodologies, and each one is unique based on the order and focus it places on each SDLC phase. Some methodologies are formal standards used y government agencies, while others have been developed by consulting firms to sell to client. Many organizations have internal methodologies that have been honed over the years, and they explain exactly how each phase of the SDLC is to be performed in that company. There are many ways to categorize methodologies. One way is looking at whether they focus on business process or the data that support the business. There are three types of system development methodologies, it is called Structured Design, RAD (Rapid Application Development), and Agile Development. Types of Software Development Methodologies Structured Design This is the first type of system development, it is introduced in 1980s. This methodology adopts the formal step by step approach to the SDLC, it moves logically from one phase to another phase. Waterfall Model This is the original structured design of methodology, with this methodology, the analyst and users proceed in sequence from one phase to the next phase. The key deliverables for each phase are typically very long and are presented to the project sponsor for approval as the project moves from phase to phase. This methodology is referred to as waterfall development because it moves forward from phase to phase in the same manner as a waterfall. Advantages of using waterfall model: It identifies system requirements long before programming begins It minimizes changes to the requirements as the project proceeds. Disadvantages of using waterfall model: The design must be completely specified before programming begins This model required significant rework, if there is a changes in the business environment, in order to going back to the initial phase need to go through each of the subsequent phase in return. Parallel Development This model of methodology attempts to address the problem of long delay between analysis phase and the delivery of the system. Instead of doing design and implementation in sequence, it performs a general design for the whole system and then divides the project into a series of distinct subprojects that can be designed and implemented in parallel. Once all subprojects are complete, there is a final integration of the separate pieces, and the system is delivered. Advantage of using parallel model: It can reduce the schedule time to deliver a system There is less chance of changes in the business environment causing rework Disadvantage of using parallel model: The approach still suffers from problem caused by paper documents It adds new problem, sometimes subprojects arent completely independent; design decisions made in one subproject may affect another subprojects Phased Development In this model, the overall system is divided into a series of version that are developed sequentially. The analysis phase identifies the overall system concept, and the project team, users and system sponsors then categorize the requirement into a series of version. Advantage of using phased model: Quickly getting a useful system into the hands of the users While the system does not perform all the functions the users need at first, it does begin to provide business value sooner than if the system were delivered after completion, as is the case with waterfall or parallel methodology. Disadvantage of using phased model: The users begin to work with the systems that are intentionally incomplete, it is critical to identify the most important and useful feature and include them in the first version, while managing users expectation along the way. Prototyping In this model, it performs the analysis, design and implementation phases concurrently, and all the three phases are performed repeatedly in a cycle until the system is completed. In this methodology, the basics of analysis and design are performed, and work immediately begins on a system prototype, a â€Å"quick and dirty† program that provides a minimal amount of features. Advantage of using prototyping model: It is very quickly provides a system for the users to interact with, even it is not ready for widespread organizational use at first. Reassure the users that the project team is working on the system Helps to more quickly refine real requirements rather than attempting to understand a system specification on paper, the user can interact with the prototype to better understand what it can do and cannot do. Disadvantage of using prototyping model: Its fast paced system releases challenge attempts to conduct careful, methodical analysis. This can cause problems in the development of complex systems because fundamental issues and problems are not recognized until well into the development process. Software Development Methodology Comparison After do research about the types of methodology that is appropriate to be used into the project. The author compared the 4 types of methodology that is compatible with the current development. The following table is the result of using the described methodology to the project. System Characteristic Waterfall Parallel Phased Prototyping Unclear User Requirement Poor Poor Good Excellent Unfamiliar Technology Poor Poor Good Poor Complexity of the System Good Good Good Poor Reliability of the System Good Good Good Poor Short Time Schedule Poor Good Excellent Excellent Schedule Visibility Poor Poor Excellent Excellent Table 1 Methodology Comparison Selecting the appropriate Methodology According to the project objective that the author proposed, author analyze each methodology that is already been researched. The author decides to use the Phased Methodology. The main reason on why the author uses this methodology is because the author would develop this system all by himself and the project will be easier to be built phase by phase. Other considerations in choosing this model are: User Requirement: the requirement of the system is clear, which is to address the problem of inefficiency and ineffectiveness of conventional way in notify the student for announcement. Familiarity with Technology: for designing the website, PHP, VB.Net language technology is going to be used, since it is still in area of the author expertise. System Complexity: the complexity of this project is at medium level, since the author familiar with the technology used in the project so it is not really difficult. However the author still need to do research on certain area of technology, for this case the knowledge of SMS gateway, and how to integrate the web based system with the SMS gateway. Duration: the duration of developing the project is approximately 4 months in order to fully complete the project. Development Method: it is a web based application that is built using the PHP, and VB.NET as the programming language. Area of Research Certain areas that we research for this project are: How to create easy and manageable database system? What is SMS (Short Message Service) portal and SMS (Short Message Service) gateway? How to integrate web based system with SMS portal? How to create easy and manageable database system? This part is one of the crucial parts in order to make a good web based application system. Therefore, creating an easy and manageable database system is really important. The database system that the author used to manage the College Announcement System web based application is MySQL. Several reasons become the consideration of choosing the MySQL software are, first reason is because the main programming language system that the author built is using the PHP technology, and PHP language has an integrated connector that able to connect it to SQL. Second reason, MySQL is open source software so it is free for download, it is will help in determining the project cost development. There is other software which is better than MySQL but looked back at the scope of the project; this is just an undergraduate project, then the author decides that using MySQL software is a wiser choice. The third reason, the author already took the MySQL subject during the study in Sunway University College, which is still in the author expertise. However, if this system wants to be implemented into the real organization, further study to create easy and manageable design is needed. When the project is already on the run, this would be very beneficial in doing maintenance of the application system. How to integrate the Web based System with SMS portal? As most people known that SMS is the most famous service that a mobile phone give. It is a service where the users able to send short text message from a mobile phone to another mobile phone. Basically the SMS would not work with just the mobile phone itself, it I because the Mobile Phone Network Operator that give the service so the SMS can be delivered to the recipient by the help of the mobile phone device as the medium to type the message. The SMS can travel all the way from the sender device to the recipient device must go through a pathway through a network called SMSC (Short Message Service Centre). SMSC works as a hardware that stores the SMS that is sent from a mobile phone then forward it again to the recipient. From the early of 1990s, the era when the first SMS is sent through the network using the mobile phone device. Nowadays with the advancement of the technology, SMS not only can be done through using mobile phone but can be integrated in other application such as web based application system, using the SMS gateway technology. However, the SMS that is sent still have to go through SMSC, which is still needed to use the SIM Card that is given by the mobile network operator. SMS gateway act as a bridge the platform that cannot use the mobile phone SIM Card to use the mobile service by using the GSM modem, in this case the mobile service is to send the SMS. The mobile SIM Card will be inserted into the GSM modem. GSM modem will act as the third party to connect to the SMSC. The web based application store the message that will be sent into the database, and the GSM will retrieve the data from the database and ready to send the SMS to the destination number. The basic function of SMS and e mail is the same, for email the sender need to enter the destination email and for SMS the sender need to enter the destination phone number. The difference is why SMS is more popular than email is because it is mobile and user can send and receive SMS wherever they are. The mobile advantage of using SMS is the reason that makes the author choose the SMS application system to be added into the College Announcement Notification system instead of using email. Another reason the author choose to use SMS is because most of the students in Sunway didnt have mobile phone that can handles in receiving and sending email, but most of the students have mobile phone that enable them to send and receive SMS. Therefore, using the SMS as additional software into College Announcement Notification system is the best choice, and the author also learn to use the GSM modem and the implementation of it into the system. Software / Hardware Requirements In order to make this project successful there are some hardware and software which is required to use in order to complete the project are: Software and Hardware requirement to develop the system. Software: SQL YOG: is the database software that the author chose to be implemented inside the College Announcement Notification system. SQL Yog had the user friendly interface and it is open source software. XAMPP: this software is applied as the localhost to compile the web based application. Adobe Dreamweaver: is the software that makes it easier to edit the coding for PHP, JAVA. Hardware: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD Software and Hardware Requirement to run the system. User Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD User Side Software Requirement: Web browser: Mozilla Firefox, IE, Google Chrome, etc Server Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD GSM Modem Server Side Software Requirement: Adobe Dreamweaver SQL Yog Web Browser: Mozilla Firefox, IE, Google Chrome, etc XAMPP Server side software requirement is needed to do the regular maintenance on the system. The development software might be needed to fix error that might be occurred when the system on the run. Chapter 2: Literature Review Literature Review Literature Review is a critical look at the existing research that is significant to the work that is currently undergo. The author currently did a project; College Announcement Notification System is the project. College Announcement Notification System is a web based application system, which is proposed as a solution to Sunway University College regarding the poor information flow in Sunway University College especially School of Computer Technology. The author chose to propose the solution only to School of Computer Technology because of the course that currently taken is under it. College Announcement Notification System is a web based application, it is hoped the system would work perfectly and increasing the information flow within School of Computer Technology (SCT). The users of the system able to access the College Announcement Notification System via laptop or PC, as long there is an internet connection. The author think if it just a normal website, there is no uniqueness that makes my project different than the others. After doing research, the author decided to add the SMS feature as the instant notification system. Integrate the system with SMS feature; means need to deal with SMS gateway. The author aware that using the SMS feature is almost the same like adding the Email as the instant notification where the system is able to send automatically the posted announcement that is already posted in the website. Email is an electronic mail that worked same like a normal mail, where the users need to write the content of the letter, after that the address of the recipient is a must for the users to add. Email enables users to send and receive electronically over the internet. SMS and Email basically is the same, it contains text and to send it need to know the exact recipient email address for email and phone number for SMS. There are many email server company that is give services for the users to send and receive email such as Hotmail, Yahoo Mail, Go ogle Mail, etc. There is also an application that handles email such as Microsoft Outlook. Some advantages that email could give are emails is free for users to use like send and receive mail, it can contains richer message contents than the conventional mail did. However from the advantages that an email, there are also a few disadvantages of emails. With the advancement of the technology nowadays, the previous email only can sent the words but nowadays, users can sent not only words but can attach richer media such as picture, video, file, etc. This advantages of email were misused by some people, it enable them to send virus, malicious software, spam that can harm the recipients PC or laptop. In order to overcome this security issue, the email provider companies try many ways to increase the security but the spammer can overcome the security and still sent the spam email that may contain virus and malicious software. Using the email as an instant notification to the College Announcement Notification System is a good choice but users may not open their own email daily, usually users open their email whenever the feel like to open it. Therefore, the author proposed to use the SMS system as the instant notification. There are few reasons that become the considerations of choosing SMS to be implemented. First reason, the project is a notification system so SMS is the best choice because after the sender sent it then the recipients received it in instant. Second reason, if using email the recipients of the email need to open their own laptop or PC, and then open the email service web page, it will takes time and not instant. Most of the students nowadays had their own mobile phone and they carry their mobile phone everywhere they go, so it is one of the reason why the author choose to use SMS as an instant notification. Mobile phone user aware that open a SMS is faster than open an Email. Nowadays, ma ny mobile phone producers now produced a new mobile phone that can handles in send or receive an email. However mobile phone that can handles send and receive email is still too expensive for the most of the mobile phone users only a few that can afford that. But if the SMS only, most of the mobile phone users able to send and receive that because it is the basic function that the mobile phone offer. SMS (Short Messaging Service) As most people known, SMS is a protocol used in communication that gives way to exchange of short message from one mobile phone to another mobile phone (tech-faq.com, 2009). Nowadays mobile phone takes an important part because it provides connections to the others that in the past impossible to do. The main usage of the mobile phone is to enable users to make a phone call wherever and whenever they are, beside used to call others; other main function of mobile phone that is growing rapidly is the usage of SMS service. SMS stands for Short Message Service. It is a technology that enables the sending and receiving of messages between mobile phones. SMS first appeared in Europe in 1992. It was included in the GSM (Global System for Mobile Communications) standards right at the beginning. Later it was ported to wireless technologies like CDMA and TDMA. The GSM and SMS standards were originally developed by 3GPP (Third Generation Partnership Project) is responsible for the development and maintenance of the GSM and SMS standards. As suggested by the name Short Message Service, the data that can be held by an SMS message is very limited. One SMS message can contain at most 140 bytes (1120 bits) of data, so one SMS message can contain up to: 160 characters if 7-bit character encoding is used. (7-bit character encoding is suitable for encoding Latin characters like English alphabets.) 70 characters if 16-bit Unicode UCS2 character encoding is used. (SMS text messages containing non-Latin characters like Chinese characters should use 16-bit character encoding.) SMS text messaging supports languages internationally. It works fine with all languages supported by Unicode, including Arabic, Chinese, Japanese and Korean. Besides text, SMS messages can also carry binary data. It is possible to send ringtones, pictures, operator logos, wallpapers, animations, business cards (e.g. VCards) and WAP configurations to a mobile phone with SMS messages. One major advantage of SMS is that it is supported by 100% GSM mobile phones. Almost all subscription plans provided by wireless carriers include inexpensive SMS messaging service. Unlike SMS, mobile technologies such as WAP and mobile Java are not supported on many old mobile phone models. (developershome.com, 2008) Usage of SMS As the mobile voice communication market approaches saturation, carriers are focusing on messaging as crucial value -added service to garner more mobile subscribers and generate greater market revenue. Specifically, SMS (Short Messaging Service) is emerging as one of the most important asynchronous communication that carriers provide. It is projected that in 2009 U.S subscribers will send over 126 billion messages via their mobile phone device, generating $8.6 billion revenues (Deng, Sun, Turner, Prince, 2008). Nowadays, people are presented with a wide variety of communication media such as email, instant messaging (IM), etc. To date, most researchers have focused on the use of SMS by teenager and young adult. Recently as SMS become the needs in our daily lives, older people also recognized the convenience of using SMS. It has been reported that over 74% of the mobile phone users worldwide is using SMS text messaging (Deng, Sun, Turner, Prince, 2008). How does the SMS works? Even if you are not talking on your cell phone, your phone is constantly sending and receiving information. It is talking to its cell phone tower over a pathway called acontrol channel. The reason for this chatter is so that the cell phone system knows which cell your phone is in, and so that your phone can change cells as you move around. Every so often, your phone and the tower will exchange a packetof data that lets both of them know that everything is OK. Your phone also uses the control channel for call setup. When someone tries to call you, the tower sends your phone a message over the control channel that tells your phone to play itsringtone. The tower also gives your phone a pair of voice channel frequencies to use for the call. The control channel also provides the pathway for SMS messages. When a friend sends you an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to your phone as a little packet of data on the control channel. In the same way, when you send a message, your phone sends it to the tower on the control channel and it goes from the tower to the SMSC and from there to its destination. (howstuffworks.com, 2005) The SME (Short Message Entity), which is typically a mobile phone or a GSM modem, can be located in the fixed network or a mobile station, receives and sends short messages. The SME was sent to the SMSC.TheSMSC (Short Message Service Center)is the entity which does the job of store and forward of messages to and from the mobile station. After receiving the SME, then SMSC sent the SME to the SMS GMSC. TheSMS GMSC(SMS gateway MSC (Mobile Switching Center)) is a gateway so that MSC that can also receive short messages. The gateway MSC is a mobile networks point of contact with other networks. On receiving the short message from the short message center, GMSC uses the SS7 network to interrogate the current position of the mobile station form the HLR, the home location register. HLRis the main database in a mobile network. It holds information of the subscription profile of the mobile and also about the routing information for the subscriber, i.e. the area (covered by a MSC) where the mobile is currently situated. The GMSC is thus able to pass on the message to the correct MSC. MSC(Mobile Switching Center) is the entity in a GSM network which does the job of switching connections between mobile stations or between mobile stations and the fixed network. AVLR(Visitor Location Register) corresponds to each MSC and contains temporary information about the mobile, information like mobile identification and the cell (or a group of cells) where the mobile is currently situated. Using information from the VLR the MSC is able to switch the information (short message) to the corresponding BSS (Base Station System, BSC + BTSs), which transmits the short message to the mobile. The BSS consists of transceivers, which send and receive information over the air interface, to and from the mobile station. This information is passed over the signaling channels so the mobile can receive messages even if a voice or data call is going on. (logixmobile.com) How to send SMS using a computer?

Pluralism and the Being of the Between :: Philosophy Theology Religion Papers

Pluralism and the Being of the Between As a theologian by training and not a philosopher, I wish to explore the boundary line between the two so-called fields of study, utilizing metaphysical considerations to attempt to tackle what we would normally identify as purely theological issues, but which by their very nature beg boundary crossings. Theologians are notorious boundary crossers, often drawing upon philosophy both to generate the questions and cultivate the answers of their craft. My aim is to utilize metaphysics to explore the possibility of reorienting religious dialogue. Despite recent advances in dialogue, very real obstacles to real dialogue still remain, particularly for those who identify themselves as coming from "conservative" and "evangelical" sectors of religion who are more likely to view it as a threat to the integrity of their faith. Our world is one torn by violence and terror, at least partly motivated by religious dissent. Within this pressure-cooker of competing religious voices, there is a growin g need for theologians and to find creative ways of bringing even the most reactionary of traditionalists to the discussion table. Addressing this situation presents one of the most pressing challenges for today's theologians, and by fiat, today’s philosophers as well. The particular task of this essay is address this issue first with a criticism of the way in which the question of religious truth-claims is usually framed, moving to the development of a new framework for the discussion. I will first outline the traditional approach to this issue, pointing out how it accentuates the aforementioned problem. Secondly, I will reframe the problem using William Desmond's fourfold sense of being to formulate a stance toward religious dialogue that is more sensitive to evangelical needs. What I wish ultimately to accomplish is to provide a framework by which evangelicals can enter wholeheartedly into dialogue without a priori selling out what is most important about being evangelical. Three Stances Toward the Religious Other The standard typology used to address the issue of competing religious truth claims includes three approaches: exclusivism, inclusivism and pluralism. This typology most directly addresses soteriological issues, or how or whether a person of another religious tradition can find salvation without converting to my religion. Briefly put, exclusivism is the belief that the truth of one religion exclude the claims of others such that only one religious community can find salvation. Inclusivism generally is the belief in the ultimate

Effectiv e communication is important as ensures  that is  clear, concise, accurate, informative and most of all non-judgemental. Communication ensures affective team working and continuity of care. 1. 3Why it is important to observe an individual's reactions when communicating with them Communication is a two-way process when two individuals interact with each other.One person is de sender and the other person automatically becomes the receiver. Observing face and body reaction is very important because only 70-80% of communication is verbal so for that reason if you don't pay attention you can miss out on a large proportion of the communication. When working with an individual, supporters must get to know the person well and learn the best way to communicate with them as everyone has different needs. 2. 1Show how to find out an individual's communication and language needs, wishes and preferences.There are many ways of communication and people communicate in all sort of different ways, for that reason we should try to communicate with the person we are caring for in the easiest way as possible. One of the ways to find out a person's needs and preferences is by asking the person themselves as they are your best source of information. Otherwise you can speak to a family member or a close friend as they will probably have a great source of information. Another way to find out your clients wishes and preferences is by reading their care plan or asking a colleague with previous experience with a client. . 2 Demonstrate communication methods that meet an individual’s communication needs, wishes and preferences. Overcoming language differences and communication. First of all you will need to find out where the person is from and their culture, a use of a dictionary in their language will also help and be prepared to learn a fill words in their language. Other ways of overcoming the language barriers is the use of flashcards to indicate there needs but the most ef fective way communication with a person who speaks another language is a non-verbal communication.The use of gestures can also be helpful but bear in mind that some gestures can be extremely offensive in some cultures. An interpreter is also another alternative in a serious discussion. A smile and a friendly face can be the key to overcome communication barriers. Meeting communication needs for someone with a hearing impairment. First of all make sure the persons hearing aid is working properly, installed with working batteries, clean, and that the person hearing aid is fitted correctly. Ensure the place where you sitting is quiet, light, and close enough so that the person can see your face clearly.Some people with hearing impairment will lip read while others will use a form of sign language for communication. Give the service user extra time to process what you are trying to say, speak clearly and in the right tone of voice. Meeting communication needs for someone with visual imp airment. As a carer we should know that a person with visual impairment is not sure what is going on around them because of their disability. The ways of overcoming that barrier: –  making sure that you introduce yourself when entering their room -speaking clearly in a right tone of voice using touch to the hand and arm as saying you are concerned and sympathetic -find out from the client what system of communication they require -never take the arm of someone who is visually impaired to help them move around, allow the person the person to take your arm and ask for guidance. Meeting communication needs of people with physical disability. – There is different ways to deal with disability because it would depend on the nature of the disability or illness. For example if your client had a stroke you will need to use very short sentences, speaking slowly and allowing the person to process what you have said and compose a reply.Using gestures and simple questions which o nly need a yes or a no answer is always a good method of communication. Writing, drawing or using flash cards is also another way of communication. – Neurone disease or cerebral palsy can also lead to speech difficulty, it means that there is no need to speak slowly as the person will understand perfectly what you are saying but it will be difficult to reply back to you. Also you will have to become familiar with sounds and the way the person communicate. Meeting the communication needs of people with a learning disability.When working with people with learning disability you have to adjust to their way of communication. You should gatherer essential information about the person and their level of understanding and kind of communication is most effective. One of the ways to communicate with a person with learning disability is physical contact, some people have a better understanding with physical level rather than a verbal level, but this will depend in each individual. 2. 3 How and when to seek advice about communication The best way to find out in who to communicate with a person is asking themselves.However if communication is not possible you can ask their family or a close friend. Nevertheless when communication is hard and you fill that the person you are communicating with is not capturing the message you should seek advice by asking your line manager in getting specialists or organisations involved and helping you to communicate. There are many organisations with specified knowledge about communication with individuals with sensory loss. Do not assume you can do everything yourself. You should seek advice  whenever you have doubts so you can provide the best service possible. . 1 Identify barriers to effective communication There are many barriers which effect communication. Culture is one of them. We take for granted that everyone has the same view of point of communication. In some cultures a younger person shouldn't have eye contact with th e oldest and some articular gestures can be very disrespectful. The is also the language barrier, so remember when communicating with a person who speaks a different language from you, you should speak clearly, using proper words without abbreviation, in a right tune of voice.Communicating with people with sensory loss can be a barrier. The best way to overcome the barriers: -list the problems to the communication. -list the ways you could try to overcome the communication problems. 3. 2Demonstrate ways to reduce barriers to effect communication -making the person feel as comfortable as possible -use gestures and pictures -give extra time for the person to process what you have said -smile, showing a positive expression -be warn and encouraging -make use of a dictionary if needed -speak clearly in a right tone of voice check hearing aid to see if it is working properly -use appropriate signing -use writing communication -reduce noise and improve lighting -repeating information if ne cessary -keep calm and remain patient -keep conversation sort and simple with someone who has difficulty in replay -judge appropriate level of communication -make sure conversation has been understood Remember you should always give your client the opportunity to express their needs and preferences Demonstrate ways to check that communication has been understood Making sure the person understood the conversation is vital.You can do that by: -listening effectively -ask the person to recap the discussion -maintain eye contact, to the person’s reaction -use of body language -make use of questions like (what, how, why, when and where) -showing interest to the conversation by leaning slightly -check their facial expression to see if the person has engaged in the conversation. 3. 4 Identify sources of information and support or services to enable more effective communication Language issues: You may need the service of an interpreter.You can find details of how to contact one from: your line manager, social services, police, embassy or the consulate of the person in need. Illness that affect people’s ability to produce sounds, use their neck and facial muscles may need the use of assistive technology. Some people will need advice of a speech and language therapist. People with sensory loss can use the NRCPD. This includes sign language, interpreters, lip readers, deaf blind communication and note takes. 4. 1Explain the term confidentialityConfidentiality means not sharing information about someone’s private personal information without their knowledge and consent. 4. 2Demonstrate confidentiality in a day-to-day communication in line with agreed ways of communication All the  information someone gives or is given on their behalf to an organisation is confidential and it should not be passed on. In some situations personal information needs to be passed on to a hospital, residential home, to a private agency. However only the information which i s required should be given.It is unethical to disclose of any information or talk about peoples personal issues with family, friends and colleagues. 4. 3 Describe situations where information normally considered to be confidential might need to be passed on There are many situations where confidential information should be passed on. If you receive an information about child abuse you should report the information even if the child refuses to agree. But if an adult or an elderly person has been abused you have to have their consent, you can only persuade them to allow you to pass on the information.Police might need personal information about an individual if they have been involved in a serious crime. In a situation when an individual threats to harm someone else or if they put others in danger. 4. 4 Explain how and when to seek advice about confidentiality If you are unsure when to maintain confidentiality you should seek advice from your manager whether is regarding clients or co lleagues. Maintaining trust and relationship with others is very important so check the organisation on information and confidentiality

Administration and Management of U.S. Prsions Research Paper

Administration and Management of U.S. Prsions - Research Paper Example In our world today, there are several forms of punishment being implemented in countries all over the world, including America. According to Mary Bosworth: â€Å"At the end of 2008, the U.S. was incarcerating more than 2.4 million men, women, and children in 5,000 or so custodial institutions scattered around the country. Over one and a half million (1,595,034) of these people were held under the jurisdiction of state and federal authorities serving sentences of greater than 12 months, leaving around 800,000 individuals housed in local jails, either awaiting trial, pending sentencing, or serving short-term periods of confinement of less than 12 months. Still others were incarcerated by military services or under military supervision† (Bosworth, 2010, p. 2). It can be concluded that prisons and jails play a big role in punishment while confinement is the most serious sanction being used by the courts in the U.S. Imprisonment or prison system, as a form of punishment has evolved in the U.S. and has also been adopted by other countries throughout the world. It has been regarded as a deterrent and preventive measure to lessen the crime rate. The purpose of the penalty is for the reformation of the felon. Since the U.S. does not practice death penalty or capital punishment, it is believed that convicted felons need rehabilitation, as they are subdued by a strange phenomenon which compels them to do wrong to others. Overview â€Å"It is a fact that the United States has less than 5 percent of the world's population, but has amassed almost a quarter of the world's prisoners. The U.S. leads the world in producing prisoners, a reflection of a relatively recent and now entirely distinctive American approach to crime and punishment. The Americans are imprisoned for crimes which include writing bad checks to the use of prohibited drugs and would rarely produce prison sentences in other countries. These convicts are serving longer prison sentences compared to other prisoners from other countries around the world† (New York Times, 2008). â€Å"The United States, which has the most prisoners of any country in the world, last year recorded a largest increase in the number of people in prisons and jails since 2000, the Justice Department reported in June 2007† (Reuters 2007). Due to the fact that the number of prisoners has risen of the recent years, there has been an increase in the problems encountered by the federal government. The rise in numbers has become alarming and must be closely monitored as more criminals have emerged in the recent times. And the administration and management of the U.S. prisons have now been put into issue for criticisms on the effectiveness and financial drain it can bring to the taxpayers’ money. The result of the increase has caused economic meltdown as â€Å"Billions of public safety dollars are absorbed by prison expansion and limits the nation's ability to focus on more effective strategies to promote public safety† (Reuters). â€Å"In the current economic climate, the problem will only worsen as the federal system and many states struggle to deal with high levels of overcrowding. Even the most conscientious wardens must find it difficult to offer meaningful time out of cell, counseling, treatment, adequate care or job training† (Bosworth, 2007). According to Criminal justice experts, â€Å"the increase of the U.S. prison population is attributed the record to tough sentencing laws, record numbers of drug offenders and high crimes rates. State or federal prisons held two-thirds of the nation's incarcerated population while local jails held the rest,
