All The Presidents Men Critic essays

All The Presidents Men Critic essays All The Presidents Men Critic All the Presidents Men is the story of the role of the press and Washington Post reporters Bob Woodward and Carl Bernstein in the Watergate scandal that forced Richard Nixon from his Presidential office. In the run-up to the 1972 election, Bob Woodward covers what at first appears to be a third rate break-in at the Democratic Party National headquarters located in the Watergate Complex. Five men in business suits, four of whom were Cubans, were caught attempting to electronically bug the office of Mr. OBrien, a Democrat. He is surprised to find top lawyers already on the defense case, and the discovery of names and addresses of Republican fund organizers in the address book belonging to one of the burglars further arouses his suspicions. The editor of the Post, Benjamin C. Bradlee, is prepared to run with the story and assigns Woodward and Carl Bernstein to work on the developments together. The two begin making phone calls and discover that there was a secret security fund collect ed in Maurice H. Stans safe for the purpose of illegal activities by the Committee to Re-elect the President. Woodwards anonymous high-level source called Deep Throat would meet him in a dark parking garage in the middle of the night, and through him, the reporters find the trail leading higher and higher in the Republican Party, and eventually into the White House itself. The ruthless committee hired hundreds of people to sabotage democratic activities and even go as far as ruining the campaign of Edmund Muskie through the Canuck Letter, written by the Deputy Director of Communications in the White House, Kenneth W. Clawson. The reporters attempted to interview the Grand Jury from the previous trials with Liddy and McCord but the members had alerted prosecutors so Judge Sirica called them to court and anonymously condemned their actions and gave them a speech o...

The Changeling Essays

The Changeling Essays The Changeling Essay The Changeling Essay He believes he loves her and this over rides any other consideration, despite the advice of his servants that to travel now would be the best option. This reinforces the theme of lust and love causing the characters to make rash decisions. Alsemero declares his love for Beatrice almost immediately, Beatrice response to this is also ironic: Our eyes are sentinels unto our judgments, And should give certain judgment what they see; But they are rash sometimes, and tell us wonders Of common things, which when our judgments find, They can then check the eyes, and call them blind Beatrice states that it is important to be weary of decided on first appearances; one should not just trust the eyes but should make a reasoned judgement. However neither Beatrice nor Alsemero do this, again reinforcing the theme of irrational passions and behaviour. Her words are hollow as they are at odds with her actual behaviour which follows what her eyes tell her. Beatrice later states, after reflecting on Alsemeros choice of friendship: Methinks I love now with the eyes of judgment Little has changed since their last meeting yet Beatrice believes she is acting rationally. This also brings in the recurring use of the imagery of sight, eyes and blindness to reflect the theme of Appearance vs. Reality and as a metaphor for reason and judgement. Unreasoned emotion is also portrayed through the relationship between Deflores and Beatrice. The contempt and disgust Beatrice-Joanna feels for her fathers servant is somewhat unfounded, as Deflores states: She knows no cause fort but a peevish will. Although disfigured and only a servant whereas she is daughter of a nobleman, Beatrice has no reason to dislike Deflores. Her irrational hatred, or peevish will has no basis and emphasizes the view that Beatrice has little rational control over her emotions and a lack of reason, nor does she understand such emotion. As the scene ends Beatrice drops her glove on the floor, and her father instructs Deflores to pick it up, It is unclear whether this is intended for Alsemero or Deflores, or whether it was accidental. However it appears purposeful and underlines the idea of Beatrices sub conscious feelings manifesting themselves and her inability to control them. Beatrice admits she has overwhelming feelings for Alsemero but that her hatred for Deflores is perhaps even stronger. One may interpret that what she sees as vehement disgust for Deflores is actually underlined by a subconscious sexual attraction to him, one she cannot control. Sexual overtones are prevalent throughout the play, for example in Deflores description of the glove or Alibius use of the ring as imagery for intercourse.

New UK GAAP - Assignment Example The need for a global reporting standard has gained more importance for small and medium sized organizations where the accountability of managers towards the investors are generally less transparent compared to large multi-national companies. Over the years such transparency might lead to mistrust between the owners and the managers leading to an Agency problem. Even though the advantage of general sets of international reporting standards are acknowledged, there are a certain implementation challenges at the international and domestic level if the objective of a harmonised and enhanced reporting structure is to be achieved. Table of Contents Executive Summary 2 Introduction 4 Advantages and Disadvantages of Global Reporting Standards 4 Importance of Accounting Standards Bodies 6 Harmonization of Reporting Standards in Recent Times 7 Conclusion 8 References 10 Bibliography 11 Introduction A considerable amount of countries and entities around the globe have adopted IFRS (Internationa l Financial Reporting Standards) as the base for financial reporting with the means and objective to enhance the value of information on corporate performance. In the year 2010, a potential new framework proposed by the Accounting Standards Board (ASB) to replace current Irish and UK GAAP has revised the original proposal and released 3 new drafts Application of Financial Reporting Requirements FRS 100, 101, 102, etc. ... ts to FRS 102 (FRED 48) which was issued on October 2012 restricted the proposed scope and amendments relating to accounting of service concession arrangements and multi-employer pensions. In addition, FRED 48 also contains proposed comprehensive accounting standards based on IFRS for Small and Medium-sized Entities. Even though the advantage of general sets of international reporting standards are acknowledged, there are a certain operational challenges at the international and domestic level if the objective of a harmonised and enhanced reporting structure is to be achieved (FRC, 2013, pp.3-12). Advantages and Disadvantages of Global Reporting Standards The need for a global reporting standard has gained more importance for small and medium sized organizations where the accountability of managers towards the investors are generally less transparent compared to large multi-national companies. Over times such transparency might lead to mistrust between the owners and the managers lea ding to an Agency problem. The implication of non-transparent reporting can be better understood when one analyzes the global financial crisis of 2008. A vigilant scrutiny of the financial crisis reveals an underestimation of the risk associated with financial instruments (such as Mortgage based securities), that led to inflated expectations ultimately triggering global financial crisis. This underestimation of risk perception of the investors was primarily motivated from the improper financial reporting of entities. Hence, an establishment of suitable reporting standards for accounting along with suitable disclosures in the financial statements has become a challenging task (Kurz, 2004, pp.1-5). The industries have experienced some tremendous changes in terms of financial reporting and

Advertising promotion Essay Example | Topics and Well Written Essays - 1000 words

Advertising promotion - Essay Example The business plan for the service is that the target market will hire Darla to perform weekly errands like picking up dry cleaning and grocery shopping, or do one-off errands, such as getting shoes or watches repaired or dropping off library books. The idea is that if Darla performs these tasks, these people will be able to relax and spend more time with friends and family, and enjoy other leisure activities. Issue with the Idea The main issue encountered for implementing this idea was to generate awareness about the service to the target people so that the idea could be implemented properly. Besides this, reaching out to the target customers efficiently was also major issue faced by Darla and her errand service. Solution To tackle this problem proper communication with the target market was essential and to actualise the same Darla had to spend a significant amount of money on advertising. In addition she had to take a call whether she would go for in-house advertising or hire an ag ency to do the job. The target market for â€Å"I’ll Run for You† comprised of a pretty large population in the area and mainly included the people who either led retired or busy lives. The elderly people who were too old for errands, and the professionals who had to travel because of work, had no time to do the errands. Before deciding on the type of advertising that Darla should have considered, it is important to analyse the pro and cons of both an in-house and an advertising agency services. In an in-house agency, the cost is relatively low and with improved technology actions ranging from direct mails to development of website, can be successfully executed by a marketer. Consistency and transparency can also be easily maintained by an in-house agency (Powers, 2012). The biggest benefit of an in-house agency is that it has total control over the provider’s time, quality and activity. Most of the organisations try to maintain the core operation in-house, whic h would differentiate the business (Traxler, 2012). However the in-house agency has a relatively low buying power of media, there are hardly any fresh views, lacks specialised knowledge, and also the stress related to work is more (Smith & Taylor, 2004, p.168). In other words, in-house agencies are less experienced, less flexible and less objective (Belch, Belch & Purani, 2010, p. 102). In case of advertising agency the biggest benefit is the expertise knowledge that the agency brings on board. The agencies work in groups, and so they are likely to pick the most innovative idea and act as per the requirements of the clients. Moreover, as the crucial part of advertising is handled by the agency, a lot of significant time gets saved for the organisation to involve in other related activities (Sharma, 2011). However advertising agency is a costly affair as they usually charge a high price for the variety of services and sometimes the clients end up paying for pretty trivial reasons. Th e money involved is relatively higher as compared to an in-house agency. Besides this less involvement with and understanding of overall marketing goals of the client, and longer response time taken by the external agencies also act as dampening factors of hiring an outside agency. Recommendation Analysing the pros and cons of both in-house and outside advertising agency, it is recommended to â€Å"I’ll Work for you† to hire an outside agency which would help it in generating awareness among the target customers. Although outside advertising agency has many disadvantages, but since the business is new, it will be beneficial

Comparative Analysis Of Eigrp And Ospf Routing Information Technology Essay

Comparative Analysis Of Eigrp And Ospf Routing Information Technology Essay In this running era of technology, the technology of communication is increasing day by day. The communication networks plays important role to send any information like file or printer sharing, video streaming and voice conferencing etc and these days internet is the best medium to share information remotely and allow people to communicate, collaborate and interact with each other. All this information is managed by communication networks in which Routing Protocols are used to transfer information or packets across internet. The Open System Interconnection (OSI) reference model by International Organization for Standardization (ISO) created Routing Protocols by which network is control and able to communicate with each other around world. The main job of Router is to provide best path to packet from source to destination by using various metrics values leading to many different properties of path and then calculated the best path for packet to reach destination in network. The numbers of Routing Protocols are available to manage the network or to connect multiple networks. Internet Protocol (IP) is the most commonly known protocol among all of them and In this thesis two most widely used protocols of intra Domain Routing Protocols will be analysed, which are Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF) Routing Protocol where as EIGRP is a Cisco proprietary Interior Gateway routing protocol via Distance Vector Protocols and OSPF routing protocol is Link-State Interior Gateway Routing protocol and also consider important protocol for real time applications. C:UsersG MomiDesktopUG ProjectAsessmentsCISCO1841.jpg Fig1[14] C:UsersG MomiDesktopUG ProjectAsessmentsnetworking-router.jpgFig 2[15] Aims and Objectives All routing protocols have different performance in the network so its important to choose the right one for your network and this selection can be done on the basis of network scalibilty, convergence time and bandwidth requirements. In this Project EIGRP and OSPF Routing Protocols are chosen and the comparitive anaysis of these two protocols in real-time trafic will be take place in different senario and evaluating which protocol will give best route real-time trafic. Further in this project, different routing protocols will be discuss as their features and properties and theoritical and simulation analyse will be done with quantative metrics. The Cisco Proprietary EIGRP is based on Diffusing Update Algorithm (DUAL) and its cost is calculated on the basis of delay and bandwidth [3] . on other hand OSPF routing protocol work on the bases of DIJKSTRA ALGORITHM or Shortest Path First (SPF) and the calculation of its cost is based on bandwidth [4]. These protocols uses different algorithm to route the trafic and this can be vary in convergence time and route proccessing delay according to their calculation so this can effect the network performance. To find out which protocol have better performance in large or small network, three different network models will be designed by EIGRP and OSPF routing protocols repectively by network simulator. 1.2 Project Methodology In this project two routing protocols EIGRP and OSPF will be analyse in by three methods:- A network model will be designed with EIGRP and simulation will be done in Cisco Packet Tracer and results will be observed. On the same designed network, OSPF will be impliment and performance will be recorded. And in the last same designed network will be impliment by both OSPF and EIGRP routing protocols to simulate the performance of real-time trafic. Routing Protocols Background Routing Protocols in IP networks are important to transfer data or any packet on time and responsible for sending packets to correct destination address and also these Routing Protocols are intelligent enough to select right information from relevant source and forwarding to destination node via one-hop or multi hop. Routing Protocols in router creates routing table by collecting information from the neighbour router which helps router to calculate the best path to forward the packet. All routing protocols are usually works on layer 3 (network layer). There are many classifications of Routing Protocols for example Static routing, dynamic routing and Link-State routing protocols further classes distance vector routing protocols, RIP, VSLM and CIDR, EIGRP and OSPF. Also these protocols help to build other network communication protocols for example wireless ad-hoc networks and mesh wireless networks and many other. The network in Internet is highly dynamic that is why its protocols are equally dynamic, among all Routing Protocols EIGRP and OSPF are two widely used protocols and both comes under dynamic routing protocols, in which EIGRP is based on Interior Gateway Routing Protocols and also EIGRP contains new features by which the market potential is expanded. OSPF is also Interior Gateway Routing protocol and works on Link-state and (SPF) Shortest Path First technology. Thanks to these routing protocol technology which increases and helped in improving the communication in such a perfect and correct way around the world. C:UsersG MomiDesktopUG ProjectAsessmentshomepage.jpgFig 3 [16] Overall Routing There are many routing protocols by which routers in different networks are able to communicate with each other with different properties. The following properties will provide overall view of Routing, what properties do router use and why. Desirable Properties of Routing Loop: While providing route for packet to reach destination, routing protocol are responsible to provide loop free route in network which results as low bandwidth used during process and can be used efficiently. Demand Based Operation: The demand based operation means that protocol should provide only the information when requested by node which helps to save the valuable resources used in network. Convergence: Convergence is basically occurrence of two or more things coming together, when ever link changes router automatically notice the change and process the update by calculating the new route and also forward the updated table. Convergence is totally depends on the routing protocols if convergence occurs in network it can result in bad route calculation or may drop the packet or time out. So the routing protocol should converge as fast as possible. Security: All protocols used in routing must ensure that the packets are transmitted with security to chosen destination. Multiple Routes: Routing protocols are responsible to provide multiple routes for the packets to reach its destination from its routing table when selected link by the routers fails or if there is any congestion on a particular route, this takes time to discover new route but by some selected routing protocols it is possible for router to do this job in seconds. Quality of Service: All Protocols doesnt support Quality of Service as fact there is no widely deployed QOS aware Routing Protocols. But some protocols do support the Quality of Service depending upon their intended network use, like in EIGRP bandwidth and delay are consider with static parameters and in OSPF only bandwidth is consider with static parameters. 2.2 Routing and Metrics 2.2.1 Metrics and its Purpose The cost of path in routing is based on the metrics parameters by metrics it is possible to compare or measure the path and all routing protocols select lowest metrics value among all values to determine the best path for routers. All Routing Protocols have their own metric calculation to decide the best bath. At a stage where routing protocol learn multiple path to reach remote networks or same destination and confused to select the right one, then lowest metrics value is used by routing protocols to choose the best path after calculating and comparing the cost of each path learned by routing protocols. Each protocol has its own way to calculate metrics and compare its value as mentioned before EIGRP works on the combination of delay, load, bandwidth and reliability and OSPF uses only bandwidth and as different for other routing protocols. 2.2.2 Metrics Parameters of Routing Protocol The metrics calculation of different routing protocols may results to select different path to same destination this is because different metrics values are used by different protocols. The following metrics are usually used in IP routing protocols:- Hop Count: some protocols count numbers of routers means hops through the packet will traverse to reach the destination like in RIP packets are traverse on the path with least number of hops. Bandwidth: After calculating the metrics if value is chosen bandwidth then path selected with highest bandwidth is preferable. Load: Some protocols select their path according to the load on the link, the lowest load on link is consider the best path to reach destination. Reliability: when reliability is chosen as metrics then path with highest reliability is selected, in this process reliability is calculated by the probability of the link failure in which can be calculated as from the previous recorded link failure or counting interface errors. Cost: cost can be defined as a metrics or a policy combined with metrics because cost is basically a value which is set by administrator or IOS (Internet Operating System) to select best path. 2.3 Classification of Routing Protocols Routing Protocols can be classified as:- Static and Dynamic Routing Protocols Distance Vector (DV) and Link-State Routing Protocols (LSR) Classful and classless Routing Protocols 2.3.1 Static and Dynamic Routing Protocols Static routing is basically used in small networks as its performance is bad because routing table constructed manually in static routing and routes are also fixed at boot time of router so that is why whenever new network is added or deleted within Autonomous System (AM) network administrator have to update it manually. Therefore it has good advantage in small network in which system administrator have full control of the network but on large networks this technology fails because it is hard to manage rapid changes in network topology and configure all routes manually. On the other hand Dynamic Routing Protocols routing is more widely used in large networks because in this routing table is created automatically and updated by message exchanging with adjacent routers, which means each router in the network have information about all other routers in the network and whenever any router is added or deleted the routing table is updated by different update methods like periodic update and trigger updates. The best route in dynamic routing protocol is based on their individual metrics and rules. Not only this there are many other reason of choosing Dynamic Routing instead of Static and for Dynamic Routing, route instability and creating routing loops are only the drawbacks which may cause. The most known Dynamic protocols are:- RIP A Distance Vector Interior Routing Protocol IGRP The Distance Vector Interior Routing Protocol by Cisco OSPF A Link-State Interior Routing Protocol IS-IS A Link-State Interior Routing Protocol EIGRP The Advanced Distance Vector Interior Routing Protocol by Cisco BGP A Path Vector Exterior Routing Protocol. 2.3.2 Distance Vector Routing Protocols Distance Vector Routing determines the best path by calculating the distance to reach the destination, as the name indicates Distance means the how far is destination by hop count metrics and Vector of distance represents term of next hop router or exit interface. Distance Vector Routing Protocols works on the basis of Bellman-Ford algorithm in which routing table is created and updated periodically by broadcasting the entire routing table to each of its neighbour. In Distance Vector each router maintains a distance vector for each destination which contains the information of next hop, destination ID and the shortest distance. This Protocols works on periodic advertisement of the shortest path by each router for example router sends its Distance Vector to its neighbours periodically containing the information of shortest path then the router in neighbour receives the information and updates its routing table and send the updated table periodically to its own neighbour and this process is continue works on the entire network in the time range of 10-90 seconds as depend on different Distance Vector Routing Protocols. In these protocols the router does not have the information of the entire path to the destination router. Router only counts the number of hops and has only the information of the direction and the interface from where the packet can be forwarded. Different metrics are used to update the information by distance vector protocols like in EIGRP the diffusion algorithm is used to select the cost of path to reach the destination. Advantage and Disadvantage of Distance Vector Routing The main advantages of Distance Vector Routing are as follows:- Simple and easy to understand as they work on the basis of router advertising processes but these protocols are efficient in smaller networks Distance Vector Routing Protocols are very easy to configure as just need to enable it on router interface and also they are very easy to manage. Main Disadvantages:- Large Routing tables in large networks, results as bad performance because thousands entries in routing table. Creating loops and slow convergence Problems with Scalability and not good in hierarchical routing Although by split horizon rule and triggered updates, Distance Routing Protocols are boosted as result convergence speed is increased. 2.3.3 Link-State Routing Protocols Link-State Routing (LSR) Protocols are those dynamic routing protocols which works DIJKSTRAS Shortest Path First (SPF) algorithm that is why this protocol is also known as Shortest Path First Protocol. The router configured with LSR protocol will always chose the shortest path to reach the destination in network. In Link-State routing protocols the information is stored in database called Link-State database and this routing information is exchange among all routers in network through Link-State Advertisements (LSA). If there is any link added or changed in the network topology then LSAs is flooded to all the neighbour nodes by which routing table are updated information is stored in their own database which describes the topology of the network. The database in these protocols contains the information cost of the each link in the network and this cost is calculated by algorithm called DIJKSTRAS algorithm and the cost of each link can also be set by administrator. After all Link-State routing protocols have excellent flexibility but more complex as compare to Distance Vector and LSR protocols have less broadcast traffic. The most known LSR Protocols are Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). Advantage and Disadvantage of Link-State Routing Each router in Link-State Routing Protocol calculate the route independently, the main advantages are as follow: LSR have small Routing table which makes it react fast whenever their is change in network. LSR also have low network overhead and the size of the packet sent in network is very small. Drawbacks of Link-State Routing: Configuration is difficult which results use of large memory space. More complex as compare to Distance Vector. 2.3.4 Classful and Classless Routing Protocols Depending on the subnet mask the routing protocols can be separated as Classful and Classless routing. Classful: The Classful routing contains the same subnet mask in the network topology and the Classful routing protocols never send any information regarding subnet mask in their routing updates. The router does not belong to same network then Classful subnet mask will be applied to the route. Classful routing protocols are not widely used because they doesnt support VSLM (Variable Length Subnet Masks) and also they cannot support discontinuous networks. Classless: Classless routing protocols are just opposite to Classful as in this the subnet mask varies in the network topology and also subnet mask and network address both are included in routing updates. EIGRP and OSPF are also belongs to classless routing protocols. 3.0 Enhanced Interior Gateway Routing Protocol (EIGRP) . EIGRP is Cisco proprietary protocol and this is enhanced version of Interior Gateway Routing Protocol (IGRP) [7], EIGRP was developed in 1992 and now days this protocols is being consider as more scalable for both large and medium networks. Diffusion Update Algorithm (DUAL) is used in EIGRP for calculating the routes to destination and also EIGRP has both properties of Link-State and Distance Vector Routing Protocols as it creates neighbour relationships and advertises the routes in network topology that is why it also called as Hybrid Protocol. 3.1 EIGRP Components EIGRP rely on the following four components:- 3.1.1 Diffusion Update Algorithm (DUAL) EIGRP uses DUAL by which loops are avoided in network and this mechanism is process by following concepts of DUAL:- Successor Successor means the first router or the first hop across network which provides the least-cost path to the destination. Feasible Distance The lowest cost required to reach the destination is basically known as Feasible Distance. Reported Distance The cost of router to reach a destination in a network is known by reported distance Feasible Successor Feasible Successor provides the loop free backup path to the destination, basically Feasible Successor if neighbour router in network. Feasible Condition This is totally depend on the value reported distance and feasible distance to select the Feasible Successor, means the value of advertised Reported Distance by router to destination should be less than feasible destination to the same distance. 3.1.2 Neighbour Discovery and Recovery This method allows routers to update their table dynamically with the information of other directly connected routers to the network and this information is exchange between routers with very low overhead as sending HELLO packets periodically throughout the network, router verify the connection with neighbour router by receiving HELLO packets from it. Usually these HELLO packets are sent periodically after every 5 seconds in high speed networks and with these HELLO packets advertise a HOLD time each time when they are sent by a router to make sure the connection is alive by receiving HELLO packets back. In EIGRP the default hold time is 15 seconds. By exchanging these HELLO packets advertisements between each other in the network, router updates their outing table, if the any router doesnt receive HELLO packets in between the HOLD time of EIGRP then the neighbour router will be discarded from the routing table. 3.1.3 Reliable Transport Protocol This protocol is used by EIGRP for guaranteed and ordered delivery of EIGRP packets to all the neighbour routers in the network and also Reliable Transport Protocol supports intermix transmission of unicast or multicast packets. EIGRP packets are different; some of the packets are reliably transmitted as required and some do not need any reliability for transmission although reliability is provided whenever there is need. 3.1.4 Protocol Dependent Module To support different network layer protocols, EIGRP uses PDM (Protocol Dependent Module) like Internet Packet Exchange (IPX) and Apple Talk. http://fengnet.com/book/CCIE%20Professional%20Development%20Routing%20TCPIP%20Volume%20I/images/07fig04.jpgFig 4 [Online Available] 3.4 Advantages and Disadvantages in EIGRP The main advantage of EIGRP routing protocol are:- Loop free routes are providing by EIGRP routing protocol. The configuration of EIGRP is very easy as compare to OSPF. Low convergence time EIGRP can work with VLSM (Variable Length Subnet Mask) Routing update authentication is also supported by EIGRP Disadvantages; The main disadvantage is EIGRP is Cisco Proprietary so can be use only on Cisco products. Routers from other vendors are not able to utilize EIGRP. 4.0 Open Shortest Path First OSPF is Link-State Interior Gateway Routing Protocol and it can use by other product as well because it is not Cisco Proprietary. OSPF works with single Autonomous system and distribute the information across the network. In OSPF the cost of interface is calculated by bandwidth and this cost is inversely proportional to bandwidth, Lower cost requires higher bandwidth [3]. As mentioned before OSPF routing protocols always select the lowest cost path to all available destinations with the help of DIJKSTRA Algorithm calculation. 4.1 Protocol Structure The following information is included in OSPF protocol structure [2] Version: indicates the current version of OSPF. Type: indicates five types of packets which are HELLO Packets, Database Description (DBD), Link-State Request (LSR), Link-State Update (LSU) and Link-State Acknowledgement (LSAck). Packet Length Router ID Area ID Checksum Au Type Authentication. 5.

Further detailed information will be included as theoretically of all related routing protocols. Conclusion This contextual report was presented as the part of BSc Computer Networking final year project on Routing Protocols to provide the overview of the project information and literature research and also as Project Initiation Document, in this report the purpose of the project is clearly mentioned and further artefact will be designed and implement later with more detailed information as scheduled.

A Trip to the Dentists Office Essay -- Personal Narratives Descriptiv

A Trip to the Dentist's Office The phone rings, and I answer, â€Å"Thank you for calling Enterprise, how may I help you?† The voice on the other end asks for Andrea, and I reply, â€Å"This is she.† The voice says she is calling to remind me of my 11:00 AM dental appointment. I sigh and tell her I will be there on time. I enter the brick building and walk over to the elevator; I push the up button and patiently wait. The elevator door promptly opens, and I get in. I push the button with a number two on it, and the doors close†¦ up I go. Once on the second floor, I exit the elevator. Even before I go into Dr.Taylor’s office, I can immediately smell the mixture of wintergreen-flavored toothpaste and bleach out in the hall. As soon as I open the outer door, a blast of cool air from the air conditioner hits me in the face and makes me shiver all over. I walk in and add my name to the list on the sign-in sheet. Mindy, the gray-hared women behind the frosted glass slide window, sees me and lets me know that the doctor will be ready soon. While I wait for the dental assistant in her crisp white uniform to call out my name, I look at the fish in the large blue tank in the corner of the room. The sleek fish dart about playing hide and seek with the plastic mermaid at the bottom of the tank, while tiny silver bubbles slip to the top of the tank's surface and break silently. I then turn and see a photo album sitting on a coffee table; I pick it up only to see pictures of decaying teeth and...
