The data protection act Essay Example for Free

The data protection act Essay When the modem is switched on, it sends out an ASCII character known as DC 1. This is the transmit enable code and is decimal 17 or 11 hex. This code is received by the computer, which knows that it is able to commence transmitting data to the modem. This is the XON condition. If there is incoming traffic, the modem sends out an ASCII DC3 character. This is the XOFF condition and is 19 in decimal (13 in hex). The computer receives this code and stops transmitting data Note:   This method is be used with a serial printer. It sends out an XOFF code when its intemal buffer is full. As it prints, it reduces the amount of characters in its buffer. When the buffer has sufficient space, it sends out a DC 1 code to the computer, which resumes the transmission of data to the printer.   The ASCII codes DC 1 and DC3 stand for Device Control 1 and Device Control 3.   This method can transmit and receive text files, since the printable ASCII set ranges from 32 to I ~ Binary files (i. e. containing machine code) contain a full range of possible numeric values. This would include the values for the DC 1 and DC3 signals, which means that XON/XOFF is not suitable for transmitting and receiving binary files. RS232 Pins A summary of the uses of the main pins on a computers serial port is shown in the following table.   DTR Data Terminal ready The computer informs the modem that it is powered up and ready to be active, by switching this pin to an ON state. Most modems require to receive this signal before they will operate   DSR (Data Set Ready) The modem informs the computer that it is powered up and ready to be active, by switching this pin to an ON state. Most computer ports require this signal before they will operate CTS (Clear to Send) The modem informs the computer that it is able to accept data for transmission, by switching this pin to an ON state. The computer will not send out data while this pin is OFF   RTS (Ready to Send) The computer informs the modem that it wishes to give it data for transmission, by switching by switching this pin to an ON state The modem responds by switching its CTS line ON unless its memory buffer is full, or it is receiving incoming data.   TXD (Transmit Data) Carries the data from the computer to the modems RXD pin, to transmit data. Carries the data from the modem to the computers RXD pin, to receive data.   RXD (Receive Data) Receives the data from the modems TXD pin, to receive incoming data. Or Receives the data from the computers TXD pin, to send outgoing data.   DCD Data Carrier detect Used by the computer to determine whether the modem has an incoming carrier (i. e. whether the line is idle or not). Some communications packages must detect a DCD signal before they will carry on. This signal can be brought from the modem or can be provided locally by a wraparound. This connects the computers DCD pin to the computers DTR pin to simulate an idle condition.   RI (Ring Indicator) This pin could be used by an auto-answer modem. Its value is raised high when the phone rings. The modem informs the DTE via this change in the RI line and the DTE responds by setting its DTR line high. The modem then answers the call and data is passed from the telephone line to the DTE. * SG (Signal Ground) This pin is used as the reference for all other signal voltages. So, if a pin swings +15 it means that the pin is a 15 volts higher than the voltage on SG. This pin should not be confused with electric earth or Frame Ground (FG). Error Detection Modem communication over the normal telephone network is always prone to losses due to poor line conditions. As transmission rates become faster, the losses are increased. If an interference pulse occurred on a line a 28,800bps system, the transmission would be affected 24 times more badly than a 1,200bps system, since 24 times more data will have been transferred during that time. Serious attention needs to be paid to detecting and correcting such errors. The parity bit system described earlier is only a rudimentary check and only applies to ASCII files. Since most files are not plain ASCII, they will require to use all eight bits of the byte and there will be no parity bit. CRC Checking Data is transmitted in blocks or packets with a checksum created using the CRC (Cyclic Redundancy) method. When the data is compiled into a block prior to transmission, a mathematical formula using polynomial codes) is applied to the data to produce a check number that is unique to the data in the block. These check digits are then transmitted along with the data. The receiver stores the incoming block of data in a buffer for examination. The same formula is applied to the data in the buffer d it should produce the same answer as that stored in the check bytes. If the computed CRC figure accords with the stored CRC figure, the data in the buffer is fit to be passed on and an ACK signal is returned to the transmitting end to acknowledge the receipt of a block in good condition. If there has been any corruption of the data in the block, or even any corruption of the check bytes, then the formula produce answers that do not match. In this case, the device will request that the block of data be retransmitted This is done by returning a NAK signal to the transmitting end. A number of different block transmission techniques and error detection methods are in common use they are referred to as File Transfer Protocols and include: XModem XModem sends a 128 byte block of data plus one checksum byte constituted from the sum of all the ASCII codes the block. It then waits for an acknowledgement that it has been received. The waiting time reduces the average data transfer average. All errors are given ten retries before abandoning the file transfer. It also has a ten-second timeout; it sends a NAK signal if has not received any incoming signal after a ten second wait. A variation known as Xmodem/CRC sends the same 128 byte block but sends two CRC bytes. This increases the redundant bytes to be transmitted but it improves the reliability of the system and is used in preference to Xmodem where it is available. Kermit Kermit is a long established system used with mini-computers and mainframes as well as PCs. It also uses a 128 block and it provides a header with control information. Although it is widely available and reliable, it is a slow method. It is probably best used with noisy lines. Ymodem This method still uses 128 byte chunks but it sends eight of these chunks before sending a two-byte CRC code that covers the entire 1024 data bytes. The method also pads out the data block until it is exactly 1024 bytes. This is fast since most of the transmission is made up of real data and there is only two bytes of redundant information. However, on a noisy line, corruption of a single bit results in the entire 1024+2 bytes being re-sent. YModem is faster than XModem on good lines but worse on noisy lines. It also allows multiple files to be transferred in the one operation. The user selects the group of files to be transferred and the system sends them all during the one long operation. This is sometimes referred to as Ymodem/Batch. Zmodem The above systems send their block and then wait for an ACK or a NAK from the receiving end before sending another block. They are working in half-duplex mode, resulting in wasted waiting time. Many modem methods do not wait for a response between sending blocks. Using a full duplex system, it is still able to receive the ACKs and NAKs when they arrive but further transmissions can be undertaken in the meantime. When an ACK arrives it knows that a particular block has been received successfully, while an incoming NAK indicates an unsuccessful transmission of a block. The system keeps track by using a windowing system. Each outgoing packet is given a packet number along with the transmission. The incoming ACK or NAK will also have a packet number attached. In the event of a NAK the system knows which packet to re-transmit. The difference between the packet currently being sent and the most recent incoming ACK or NAK is known as the window. Since a single byte can contain 256 different numbers, there is a limit to the range of available packet numbers and older numbers are reused after they have accomplished a successful transmission. This means that the window covers a small range of the available numbers and is always changing. This gives the name sliding windows protocol; it is also implemented in the Sliding Windows Kermit and Xmodem systems. Xmodem, Ymodem and Kermit are used at speeds below 96,00bps. V42 is used at higher speeds and is implement in a ROM chip in the modem. The V42 standard encompasses the MNP 4 proprietary standard developed by Microcom. It is likely that future extensions of the V42 standard will move away from MNP 4 in favour of LAP-M (Link Access Protocol for Modems) scheme as already recommended by CCITT. The MNP 5 standard combines the MNP 4 error correction facilities with data compression. Like MNP 4 it is most commonly implemented in hardware although some communication packages implement it in software. Standards. Created by CCITT, The International Telegraph and Telephone Consultative Committee, working under the ITU (International Telecommunications Union) which is organised by the United Nations. These standards are divided into a number of groups, including:   V-series, dealing with telephone circuits   X-series, dealing with data networks 0-series, dealing with digital networks (digital exchanges, multiplexing, PCM, etc. )   I-series, dealing with ISDN (see later) V Standards There is a wide range of definitions and the most common ones are shown in the table. The V standards get their name from the first letter of the word vitesse, the French for speed although not all V standards are concerned with transmission rate. V24, for example, specifies the serial port standard and V42 and V42bis cover error correction. The bis added to a V number means that it is the second version of the standard. Dataflex, a large UK modem manufacturer, produces VFC models, also known V. Fast Class models, working at 28,800bps. These were introduced before the ratification of the V34 standard and there are some handshaking differences between their specifications. V. Fast modems can communicate with other VFC models at the top rate but with lA ~ ~t, ~k~1t lflO/ ~ V3 5 models, they can only communicate at 14,400 bps in about 10% of cases Modem Standards Specification Operation Circuit Max Bit Rate Modulation Technique Bell 103 Full Duplex Two Wire Switched 300 Frequency Shift Keying V. 21 Full Duplex Two Wire Switched 300 Bell 202 Half Duplex Two Wire Switched 1,200 Conditioned Lease 1,800 Bell 201 Half Duplex Two Wire Switched 2,400 V. 26ter Full Duplex Two Wire Switched 2,400 Bell 212 Full Duplex Two Wire Switched 1,200 Phase Shift Keying V. 22bis Full Duplex Two Wire Switched 2,400 Quadrature Phase Shift Keying V. 27 Full Duplex Four Wire Leased 4,800 Half Duplex Two Wire Switched 4,800 V. 29 Full Duplex Four Wire Leased 9,600 Quadrature Amplitude Modulation Half Duplex Two Wire Switched 9,600 V. 32bis Full Duplex Two Wire Switched 14,400 V. 34 Full Duplex Two Wire Switched 28,800 Bell 103 Full Duplex Two Wire Switched 28,800 V. 42 V42bis Data Comp V90 56,600 Even Parity The sending device counts the number of one bits in the character to be Panty Bit transmitted.

If the total is not an even number, there has been corruption of the data. This provides an elementary check for data errors. Odd Parity Here, the sending device counts the number of one bits in the byte to be transmitted. If the number of these data bits is even, as in the top diagram, the parity bit is set to one. If the number of one bits is already odd, as in the lower diagram, the parity bit is set to zero. In this way, the total number of ones1 in the group is always maintained at an odd value. Note Parity checking is a useful facility but it is not foolproof. For example, two bits in a byte both being altered from zero to one would produce a correct parity check although the data in the byte had been corrupted. In practice, larger blocks of data are examined for corruption (see section later on Error Detection).

Contrasting Edmund Burke And Jean Jacque Rousseau Politics Essay

Contrasting Edmund Burke And Jean Jacque Rousseau Politics Essay Two of the most influential political philosophers of the 18th century were Edmund Burke and Jean-Jacque Rousseau. That is not to say that the two men shared the same philosophical views, however; in fact, it could be argued that they were on the opposite sides of the political spectrum, with Burke on the right and Rousseau to the left. A classic example that showed the differing opinions among the two was the French Revolution. Burke was not in favor of the revolution because he maintained that it would disrupt the traditions of France that hold the country together. Rousseau, on the other hand, was a hero of the revolution because he championed liberty and the idea that the people should be in control on how they should be governed. It is amazing to think that two philosophers, having very different perspectives on politics, can both be influential during the same time period. One of the core aspects of Jean-Jacque Rousseaus philosophy was what man was like in the state of nature. In the Second Discourse, Rousseau explained that people were equal and free going back tens of thousands of years because there was no real societal organization to speak of. Since life was centralized on hunting and gathering food, people were, for the most part, equal in terms of societal stature. People were relatively free because no one had to answer to a higher authority, with the family structure being the only exception. Since people were free and equal, they were innocent and individualistic in nature. There were no outside forces that had a corruptive effect on people and there was no reason for groups of people to band together to form a society. According to Rousseau, the development of reason and private property rights ruined equality and freedom because they lead to the few dominating the many. As populations started to grow, there was a greater need for more socie tal hierarchy due to the complex nature of communities, thus less freedom and more inequality. Even though society today believes that reason is a positive thing, Rousseau insisted that progress brought the worst out in people. Rousseau was not necessarily arguing in favor of going back to the time of early humans per se. He knew that society was a point of no return, so he had to be somewhat practical. What he was arguing was to return to the roots of equality and freedom as much as practically possible. The way to achieve that goal politically, Rousseau argued in the Social Contract for a political system that put most of the power in the hands of the people and not the elites. Rousseau was a contract theorist, which meant that he believed that government should only operate with the consent of the people that it is governing. What set him apart from the other contract theorists was that he coined the term general will. What Rousseau meant was that all men should sacrifice their own individual power in order to give way to what he called the general will. In other words, all men give up some of their freedom in order to what is best for the society as a whole. The thing that is not so clear is the mechanism in finding out what the general will is. For example, is it the compilation of the opinions of individuals or is it something that is even greater than public opinion, such as having to understand human nature? Being that there were conflicting issues that faced Rousseaus politic al philosophy, he kept on falling back on the idea of radical democracy. Since Rousseau was so distrustful of political institutions in general, he felt that people should always have a seat at the table when it came to determining policy. With that being said, it would seem that Rousseau was not in favor of having a republican form of government. Instead, as noted before, he was more in favor of a radical democracy. For this reason, he was a hero of the French Revolution. The revolutionaries read Rousseaus work and were inspired to take action against the monarchy, even though Rousseau was not even alive when the revolution started. Abiding by the slogan of Liberty, equality, and fraternity! during the duration of the revolution, the revolutionaries took the cue from Rousseaus political philosophy. The practicality question enters the conversation again, however, when talking about Rousseaus radical democracy. Is it even possible for a country to function properly with every citizen participating? At what point would moving towards a representative government be too far for Rousseau? It would be interesting to find out the answers of these questions from Rousseau himself because he was more of a practical thinker than some people give him credit for. Rousseaus political philosophy would seem to be paradoxical when you think about it, which is why the interpretation of his work is still being debating to this day. Edmund Burke is widely regarded as the founder of the modern conservative ideology. Although he did not believe in adhering to abstract principles when governing, his body of work clearly showed that he valued tradition and stability above all else. Similar to Jean-Jacques Rousseau, nature played a significant role for Burke when developing his political philosophy. Burke wrote that there are two natures. The first nature refers to: the idea that people love their families and that family provides a certain amount of stability and continuity, and that people are more comfortable with what is familiar to them. Burkes second nature refers to the acquired opinions that people accumulate throughout their lives, such as habits and customs. According to Burke, the second nature is what cements society because it provides the traditions that are passed down from generation to generation. As societies and times change, people should always hold on to the traditions that are passed down becau se they form the foundation of stability. Another plank in Burkes political philosophy is practicality. He did not believe that you can run a society based on abstract philosophy because it is not grounded in reality of the current situation. Rather, he was a pragmatist who looked at issues on their face value and tried to come up with solutions that fitted the time. That is not so say that he did not have any values, however. As noted before, he was a big believer in tradition and stability. Burke just argued that overarching philosophies cannot be applied the same in every circumstance because each circumstance has its own unique qualities. Burke is famous for his criticism of the French Revolution in Reflections on the Revolution in France. He was against the revolution because he believed that it would have destroyed Frances great traditions and that the theory and practicality behind the revolution were not sustainable. Burke did not agree with the revolutionists belief that government is created to protect the natural rights of individuals. Instead, he insisted that government was there as a stabilizing force so that people could live comfortably. Also, Burke believed that culture and tradition are more worthy in being protected than natural rights of individuals because they are much more long-lasting. Another problem that Burke had with the French Revolution was the idea that society can be formed from scratch. Burke asserted that societies cannot simply start over from scratch because he believed that leaders make prudent decisions based on the conditions that are in front of them. Installing a new political regime, in Burkes point of view, is not all that practical. With that being said, Burke was not a contract theorist because contract theory provides that a new society can be created by man. Rather, he saw society as an invisible link that connected generations to each other, carrying with it the established customs and institutions. These lasting institutions should be protected and respected due to the fact that they survived, thus showing their adaptability to changing times. It can certainly be argued that Jean-Jacques Rousseau and Edmund Burke had very different views when it came to their political philosophies. Rousseau was in favor of radical democracy and did not trust societal institutions, while Burke valued tradition and stability above everything else. However, there are commonalities that the two did share. One is that both of them believed that times change, so adhering to rigid ideologies was not the wisest thing to do. Rousseau admitted that early man practices were outdated, so he was not so stubborn to strictly stick to that belief system. He did believe that the themes of equality and freedom that was present during the days of early man were everlasting enough to still be applied to his present day. Burke also acknowledged that the world does not sit still. Even though he strongly believed that tradition and stability had to be protected, he knew that life moves on. The reason why he argued for the respect for traditions and institutions that have endured several generations is due to the fact that they showed their adaptability during changing times. Related to the two mens shared view of not sticking to a rigid ideology, Rousseau and Burke both had nuanced political philosophies; neither of their philosophies were black and white. Rousseaus philosophy was so nuanced that it could be considered contradicting, as noted before. In the Social Contract, he famously said, Man was born free and everywhere he is in chains. But later on in the same work he argued for the general will and that sometimes men must be forced to be free. One could make the case that he was a libertarian, while another could equally claim that he was a totalitarian. Burke was nuanced to a lesser extent than Rousseau, but nuanced nonetheless. He knew that holding on to the past can only go so far, which is why he asserted that while times does go on, it is still important to carry on the traditions and culture that were passed on by previous generations. An interesting thing to note about Burke is that he was in favor of the American Revolution. This goes to show that he was not against all revolutions, again showing his nuanced approach to politics. The reason why he supported the American Revolution is because the colonists were not creating a society from scratch. The colonists, descendants of England, were committed to English ideas and principles. The only difference was that they wanted to a free and independent nation. The French revolutionaries, on the other hand, were hell-bent on creating a whole new political paradigm. As far as my opinion is concerned, I think that both Jean-Jacques Rousseau and Edmund Burke contributed significantly to the field of political philosophy. Even though they had different thoughts on how government should operate, both of them had valid points. I agree with Rousseau that people should have a say in the way that they should be governed because history has shown that democracies have been the most peaceful form of government and it seems to be the most fair system (at least so far). But I agree with Burke as far as remembering your societys history and culture because you would not be where you are in life if it wasnt for previous generations. I also concur with Burke that society should not change too quickly, as it might cause instability that might do more harm than good. It turns out that I am quite nuanced with my approach to political philosophy, just as Rousseau and Burke were.

Nature Imagery and the Life Cycle in Robert Frost’s The Wind and the Ra

Nature Imagery and the Life Cycle in Robert Frost’s The Wind and the Rain In his poem â€Å"The Wind and the Rain,† Robert Frost develops a central theme, presenting a man’s reflection upon his life. As the man ages, he realizes that he spent much of his life worrying about his inevitable death instead of living his life to the fullest. The man expresses his desire to renew life at all costs; he would rather die living than spend the rest of his life concerning himself with death. Robert Frost’s theme in â€Å"The Wind and the Rain,† therefore, is that life should be lived, and one should not worry about his inevitable death, for he does not have the power to control death, only the way he lives his life. Frost uses images of nature throughout the poem to support his central theme. In part I of â€Å"The Wind and the Rain,† the speaker discusses the fact that he is aging, and his death is undeniable. He realizes that he has â€Å"let [his focus on death] drive [him] deathward,† yet he has done little to change his focus. The man regrets that he spent much of his life â€Å"[singing] of death,† wishi...

Charcuterie Essay -- Food, Delicacy

Charcuterie runs the entire gauntlet of cookery. It represents an ancient culinary science that hallmarks the advent of a civilized mankind. Charcuterie is a fifteenth-century French term derived from the root words ‘chair’, which translates to flesh and ‘cuit’, meaning cooked. Charcutiers are in a specialty class of their own, distinguished from the classic butcher as a crafted meat preserver and engineer of flavor (Doherty, 2009). American consumers commonly misconceive charcuterie as a novelty or delicacy that is not readily available, when in fact charcuterie is everywhere. Oscar Mayer cold cuts, a modern day American staple, are produced by a preservation technique used before the concept of refrigeration. From the humble isle ways of local supermarkets to the posh pantries of restaurateurs and the finest charcuteries, a primitively preserved slab of hog is an ode to any carnivorous appetite. Charcuterie is mastery of the art of creating sausages a nd other cured, smoked and preserved meats (Ruhlman and Polcyn, 2005). Charcuterie mimics the dynamic trends of the culinary arts and continues to garner new delectable spin on time-tested classics. Preservation was cooking’s catalyst and in essence conjured the concept of a chef! The distinct flavor of charcuterie is as rich as its heritage. The origin of charcuterie is saturated with traditions, controversy and has stood the test of time in a competitive industry with rivaling styles. Charcuterie is both art and a science; the mechanics should be explored in order to appreciate the relevance of a taste that is as old as humankind. Remnants of charcuterie date back to the origins of Homo sapiens. Charcuterie was the groundwork for human survival in virtually every culture. ... ... been rehabilitated through consumer awareness and activism that led to better sanitation practices, overall care and slaughter. Swine is the reigning creature of charcuterie, palatable from head to tail! Charcuterie is an intricate part of the culinary scene. Chefs have implemented exquisite adaptations of preservation techniques to showcase charcuterie in contemporary dining. Variations from different regions ripened a romance between charcuterie and international cuisine. A French farmer would alchemize scraps of meat to make â€Å"waste† palatable is nowadays offered as patà © (Ruhlman and Polcyn, p 22)! Charcuterie cannot nor should not be precisely defined; it is something to be experienced. The historical nature of charcuterie connects you to your ancestors in a tangible way. Culinary art is a by-product of a rudimentary need to sustain and preserve life.

Destructors/the Lottery Compare and Contrast Essay

While the characters in the two short stories Destructors by Gramham Greene and The Lottery by Shirley Jackson had unexpected endings the characters varied in qualities, emotions, and motivation. Each story seems to reveal a surprising outcome and turn of events as their personalities unfolded. As the climax grew the outcome was not so predictable. In the Destructors the main characters were T (Trevor), the house, and Mr. Thomas (Old Misery). Trevor was the new recruit and was described as being very silent and reserved. The author begins to paint a picture of how Trevor’s life used to be. It stated that his father use to be an architect but is now a clerk as they have â€Å"come down in the world† (Greene). His mother had even viewed herself as being better than the neighbors. Trevor was very upset with the middle class and wanted to take his revenge and frustrations out on a nearby neighbor’s house, Old Misery’s. Starved with envy he concocted a scheme to destroy the house not just by vandalizing the property but by literally destroying it from the inside out until there was nothing left. It seemed as though no one really new Trevor and would have envisioned what he was actually capable of. The emotions, attitudes, and the behaviors of Trevor were intense as he was obsessed with destroying Old Misery’s house. His emotions seem to get out of control as Mr. Thomas ends up arriving home early and the rest of the Gang is ready to bail as the fear of getting caught presents itself. â€Å"Trevor yells that it is not fair. † This statement is very important as it now reflects and shows the drive and passion for destroying Old Myserys house. Blacke a fellow gang member agrees to stay and complete the tasks at hand. I thought that Trevor was very selfish for his acts. It was not right to destroy someone’s home due to envy. Later in the story he shows his compassion as he locked the Mr. Thomas in the shed and gave him some food and a blanket so that he didn’t starve or get cold during the night while they completed the job. The motivation behind Trevor’s actions was that he was upset that his house and lifestyle had been destroyed. Statements early in the story like â€Å"Wren built that house father says† reflects that T was in deep though regarding Old Misery’s house. At first the text didn’t reveal his thought and actions but as the story was told his actions were known. There are various events in the story that make you question his motivation as they find Old Misery’s money. Blacke asked Trevor was he going to steal and he says no that they were not thieves and end up burning it. It’s odd that you can view taking money as a thief but not find fault in destroying someone’s home. The fact that he even burned Old Misery’s money depicted this overwhelming need for Old Misery to experience the financial strain that he and his family was experiencing. Unlike the Destructors who had only a few characters there were many characters that made a brief appearance in the story. The author really didn’t go into great detail regarding one individual but provides just enough to set the foundation of each character. The main characters of this short story were Tessie Hutchens and The Lottery. Tessie Hutchens played a major role as I felt she was the protagonist in the story. Tessie stands out from the beginning as she arrives late to the Lottery. The fact that she was doing house work and almost forgot what day it was shows that she had very little concern. The emotions, attitudes, and the behaviors of that of the Lottery were very similar to that of the Destructors. The community carried out this horrible tradition without a second thought. Tessie was very selfish as she was willing to sacrifice her family to save herself. Everyone was well aware of the rules and regulations of this traditional event. Bill Hutchinson selected the slip of paper that would put his family in the drawing for the Lottery. But once Tess had won the Lottery she goes into a rampage and panics stating â€Å"You didn’t give him enough time to take any paper he wanted. I saw you. It wasn’t fair! † She demanded a recount and gave various excuses why they should start over. During her outrage and panic she goes as far as to suggest that her daughter and son in law should be included in the Hutchinson family. The proctor of this event states â€Å"Daughters draw with their husbands’ families, Tessie, and that â€Å"You know that as well as anyone else. † It’s odd that she didn’t think enough of the Lottery to show up on time but now that she has won the Lottery it’s a different story. At first glance you couldn’t tell the motivation of Tess. As it wasn’t clear as to what the Lottery was. At first the story had a sense of calmness by all involved It wasn’t until the end of the story that it was revealed what the lottery actually meant.. The fact that Tess was protesting the matter showed that it could not be a good thing. Her panic was created in the fear of her being stoned to death. She was also willing to break a tradition that had been conducted for over 76 years because she had won. As long as she didn’t win the lottery she had very little concern. But in the end everyone around her was eager to carry out the tradition and get on with their day. The reasons of this tradition were never revealed but it was conveyed that this was something that was carried out every year without a second thought. Both of these stories carried very unbelievable and disturbing situations. In some ways they were alike and in others very different. In the destructors it was a bit concerning that a young boy could have so much anger towards a house and be mad because of his situation. As a result he then passed on that anger and resentment to a fellow neighbor. The character Trevor seemed to not think about anyone else but himself. The story left me feeling sorry for Mr. Thomas as he now had no house and money. In the Lottery its questionable on how so many people could go along with such a horrible tradition and the lack that no one would even question the validly of it. It also showed that Tess was very selfish as she was willing to sacrifice anyone but herself. It makes you wonder how a mother could even fathom to put their child in their place for such a heinous act. In the end this reveals a scary side of human nature.

Copd

COPD Chronic Obstructive Pulmonary Disease is treatable and can be prevented. It can greatly impact a patient’s lifestyle. The disease varies person to person and usually progresses. The two major components of COPD are inflammation and airflow limitation. Treatment and prevention of COPD is aimed at treating these. There are four stages of COPD; Mild, Moderate, Severe and Very Severe. Signs and symptoms for all types of severity are; possible cough, sputum and dyspnea, shortness of breath, wheezing, chest tightness and chronic cough. Diagnosing COPD and staging is predicted by the pulmonary function test results, and also again by possible symptoms. Treatment recommendations differ between the different stages of the disease. Treatment for COPD includes a new medication called roflumilast (Daliresp) which selectively inhibits Phosphodiesterase 4 a major AMP metabolizing enzyme in a lung tissue. The therapy goal with that rate of exacerbations improve ABG's pulmonary function tests and decrease the need for rescue medications. Also there is short and long acting inhaled beta antagonists. They are comprised of a cortiosteroid, bronchodilators and they reduce inflammation. Antibiotics can also be prescribed to reduce any increased sputum volume and dyspnea. Oxygen therapy also helps with COPD by improving breathlessness during exercise and daily living. Application to Nursing: COPD COPD has a dramatic impact on a patient’s lifestyle, it is preventable and treatable. Therapy treatments vary with the four stages of severity. Avoiding the risk factors for COPD and getting an influenza vaccine can help for all four of the stages. A short acting bronco-dilator can be used PRN for mild-moderate stages. Regular treatment with one or more long acting bronco-dilators can be used for moderate-very COPD. Rehab therapy is used for moderate COPD. Inhaled glucocorticosteroids are used for severe-very severe COPD. When the patient has very severe COPD they will be on long term oxygen, and also can or will be considered for surgical treatment. Patients with COPD will need support and possible motivation to participate in daily activities due to worry some behavior and or depression, fatigue and increased dyspnea Exercise and smoking cessation is the best intervention for people who have been diagnosed with COPD. This will possibly lessen the troubles that can arise from this disease.
