Advantages and Disadvantages of Having a Mobile Phone

This is a quite hot topic,espeaially for students in campus! net has collected this sample coposition for you! 1. 2. 3. Nowadays,with the rapid development of IT and information industry, cell phones play a dominant role in towns people's life. But, like everything else, they have both favorable and mffavorahle aspects. First, it's useful. As a wireless mobile telephone, it's easy and handy to early to wherever one goes and call the callee however far away he is. Therefore, it greatly facilitates people's life. Second, it's convenient. Whenever one meets trouble or something urgent, one can nmke a call immediately. Most important of all, it's a very helpful companion. With a multirfunction cell phone in hand, one can easily get on the Net, browsing the useful information, conducting e-commerce and doing whatever one can do via Internet. However, just as everything has two sides, the cell phone also has many disadvantages. To begin with, it's expensive to buy and costly to pay the hills, esp. that of global service. To make matters worse, it's also easy to lose and costly to get it repaired. Worst of all,it's not as clear as a family telephone and sometimes the number dialed is often not available. Last but not least, it's alleged the microwaves in it might do harm to people's health. In my opinion,with its expenses greatly reduced after China's entry into the WTO, it will face an ever brighter future in its development. Someday most of them will be developed into new Intemet-enabled mobile phones, which will be as useful as pocket computers. And I believe its advantages will not only offset its disadvantages, but also far outweigh them.

An Argument Against the War in Iraq essays

An Argument Against the War in Iraq essays The recent war with Iraq has been on the minds of people all across the world since well before it started. Many are worried that the United States will be seen as being too controlling, and that it should let the Iraqi people work out their own problems. Others, who are concerned about the threat of terrorist activity in this country and others, stick with the belief that the United States was right in their attempt to remove Saddam Hussein from power. Regardless of which opinion one holds, there are theorists, both classical and modern, who have strong views on war. This is largely due to conflict theory, which is that life is largely characterized more by conflict that it is by consensus. Those who uphold this theory have different ways of looking at it, and the purpose of this paper is to look at classical theorists such as Karl Marx and Max Weber, as well as modern theorists such as Ralph Dahrendorf, and Lewis Coser. The different views they have of conflict theory will th en be applied to the war in Iraq, to help show what they believe about conflict and why it is important. I will, however, refute many of their arguments because I am strongly against the war in Iraq and the pain and suffering that it is causing so many people. Once an understanding of conflict theory is established based on how these particular theorists choose to view it, a comparison and contrast of the beliefs that they hold will be discussed as well. This is important in understanding not only conflict theory, but how it applies to real-life situations such as war. Conflict theory can be used in other situations, but war is one of the most obvious and violent ways that countries deal with conflict, and is therefore a good way to discuss the different theories that are related to conflicts between individuals. Classical theorists include Karl Marx and Max Weber. Karl Marx is basically the father of conflict theory, and many of the conflict and ot...

Take Time to Wrap Up the School Year in 3 Steps

Take Time to Wrap Up the School Year in 3 Steps By the time any school year winds down to a close, the last thing any teacher wants to think about is the next school year. Unfortunately, the end of the school year is also when a teacher has the most information about how to make the transition into September much smoother. So, how to make the best use of this information? Teachers should try to spend time -a few hours on each of the following categories- at the end of this year because time invested now  could yield positive results in the next school year. #1. Spend Time Cleaning Up and Cleaning Out Before a teacher leaves for the school year, he or she could take a picture of the room (maybe from several angles) and post these pictures on the bulletin board for the custodial staff to see. This will make sure the room is organized and ready for students in the next school year.   Teachers should box supplies and clearly labels them so materials can be located quickly.( NOTE: Painters tape is more easily removed than other kinds of masking tape if furniture is marked.) In cleaning out, teachers and staff should follow the following guidelines: Remove the materials that were not used this year.Go through files and purge what is outdated. Remove  items that are irrelevant Remove saved items that â€Å"might†¦Ã¢â‚¬  be used. Do not keep those unused items inherited from teachers who came before...and do not feel guilty. #2. Spend Time Reflecting on Goals: If the teacher evaluation program (EX: Danielson or Marzano) has a self-reflection requirement, then much of this effort is already done. A teachers self-reflection can help him or her to focus on what areas might need attention in the next school year. If there is no self-reflection, teachers can still review the following questions in order to draft a goal or set of goals for the coming school year: How can I improve on writing this same or a similar goal for next year?What new ways could I use to measure this same goal or a new goal?Can I use different groups to make growth more visible?What could be the next step after meeting this goal?What single factor was most helpful with my goal this past year?What single factor caused problems with meeting my goal this past year?How can I improve my use of time in meeting a future goal? #3. Spend Time on Preparing Special Events Teachers can do a little pre-planning during the summer to alleviate the stress of planning special events (field trips or guest visits-in person or virtually) for students during the school year. Contacting locations or guest speakers in advance of the school year will help provide the school office personnel the time to plan for logistical support (transportation, permission slips, substitutes, video chats) well in advance, especially when the school calendar is being created. Special events are what students remember about the school year, and a little planning in advance can make the effort for all stakeholders worthwhile. In spending a few hours at the end of the school year on each of the three suggestions above, teachers can leverage their experiences of this past school year in order to make positive steps towards making the next school year experience even better.

CSS Alabama - Civil War - Confederate Raider

CSS Alabama - Civil War - Confederate Raider Nation: Confederate States of AmericaType: Screw SteamerShipyard: John Laird Sons, BirkenheadLaid Down: 1862Launched: July 29, 1862Commissioned: August 24, 1862Fate: Sunk, June 19, 1864 CSS Alabama - Specifications Displacement: 1,050 tonsLength: 220 ft.Beam: 31 ft., 8 ft.Draft: 17 ft., 8 in.Speed: 13 knotsComplement: 145 men CSS Alabama - Armament Guns 6 x 32 lb. guns, 1 x 100 lb. Blakeley Rifle, 1 x 8 in. gun CSS Alabama - Construction Operating in England, Confederate agent James Bulloch was tasked with establishing contacts and finding vessels for the fledgling Confederate Navy. Establishing a relationship with Fraser, Trenholm Company, a respected shipping company, to facilitate the sale of Southern cotton, he was later able to use the firm as a front for his naval activities. As the British government remained officially neutral in the American Civil War, Bulloch was unable to purchase ships outright for military use. Working through Fraser, Trenholm Company, he was able to contract for the construction of a screw sloop at the yard of John Laird Sons Company in Birkenhead. Laid down in 1862, the new hull was designated #290 and launched on July 29, 1862. Initially named Enrica, the new ship was powered by a direct-acting, horizontal condensing steam engine with twin horizontal cylinders which powered a retractable propeller. In addition, Enrica was rigged as a three-masted barque and was capable of employing a large spread of canvas. As Enrica completed fitting out, Bulloch hired a civilian crew to sail the new vessel to Terceira in the Azores. Reaching the island, the ship was soon met by its new commander, Captain Raphael Semmes, and the supply vessel Agrippina which was carrying guns for Enrica. After Semmes arrival, work began to convert Enrica into a commerce raider. Over the next few days, sailors endeavored to mount the heavy guns which included six 32-pdr smoothbores as well as a 100-pdr Blakely Rifle and an 8-in. smoothbore. The latter two guns were placed on pivot mounts along the ships centerline. With the conversion complete, the ships moved into international waters off Terceira where Semmes officially commissioned the s hip into the Confederate Navy as CSS Alabama on August 24. CSS Alabama - Early Successes Though Semmes had sufficient officers to oversee the running of Alabama, he had no sailors. Addressing the crews of the attending ships, he offered them signing money, lucrative bonuses, as well as prize money if they signed on for a cruise of unknown length. Semmes efforts proved successful, and he was able to convince eighty-three sailors to join his ship. Electing to remain in the eastern Atlantic, Semmes departed Terceira and began stalking Union whaling ships in the area. On September 5, Alabama scored its first victim when it captured the whaler Ocumlgee in the western Azores. Burning the whaler the following morning, Alabama continued its operations with great success. Over the next two weeks, the raider destroyed a total of ten Union merchant ships, mostly whalers, and inflicted around $230,000 in damage. Turning west, Semmes sailed for the East Coast. After encountering poor weather en route, Alabama made its next captures on October 3 when it took the merchant ships Emily Farnum and Brilliant. While the former was released, the latter was burned. Over the next month, Semmes successfully took eleven more Union merchant ships as Alabama moved south along the coast. Of these, all were burned but two which were bonded and sent to port loaded with crewmen and civilians from Alabamas conquests. Though Semmes desired to raid New York Harbor, a lack of coal forced him to abandon this plan. Turning south, Semmes steamed for Martinique with the goal of meeting Agrippina and resupplying. Reaching the island, he learned that Union ships were aware of his presence. Sending the supply ship to Venezuela, Alabama was later forced slip past USS San Jacinto (6 guns) to escape. Re-coaling, Semmes sailed for Texas with the hope of frustrating Union operations off Galveston, TX. CSS Alabama - Defeat of USS Hatteras After pausing at Yucatan to conduct maintenance on Alabama, Semmes reached the vicinity of Galveston on January 11, 1863. Spotting the Union blockading force, Alabama was seen and approached by USS Hatteras (5). Turning to flee like a blockade runner, Semmes lured Hatteras away from its consorts before turning to attack. Closing on the Union sidewheeler, Alabama opened fire with its starboard broadside and in a quick thirteen-minute battle forced Hatteras to surrender. With the Union ship sinking, Semmes took the crew aboard and departed the area. Landing and paroling the Union prisoners, he turned south and made for Brazil. Operating along the coast of South America through late July, Alabama enjoyed a successful spell that saw it capture twenty-nine Union merchant ships. CSS Alabama - Indian Pacific Oceans In need of refit and with Union warships searching for him, Semmes sailed for Cape Town, South Africa. Arriving, Alabama spent part of August undergoing a badly-needed overhaul. While there, he commissioned one of his prizes, the bark Conrad, as CSS Tuscaloosa (2). While operating off South Africa, Semmes learned of the arrival of the powerful USS Vanderbilt (15) at Cape Town. After making two captures on September 17, Alabama turned east into the Indian Ocean. Passing through the Sunda Strait, the Confederate raider eluded USS Wyoming (6) before making three quick captures in early November. Finding hunting sparse, Semmes moved along the north coast of Borneo before overhauling his ship at Candore. Seeing little reason to remain in the area, Alabama turned west and arrived at Singapore on December 22. CSS Alabama - Difficult Circumstances Receiving a cool reception from British authorities in Singapore, Semmes soon departed. Despite Semmes best efforts, Alabama was in increasingly poor condition and badly needed dockyard refit. In addition, crew morale was low due to poor hunting in eastern waters. Understanding that these issues could only be resolved in Europe, he moved through the Straits of Malacca with the intention of reaching Britain or France. While in the straits, Alabama made three captures. The first of these, Martaban (formerly Texas Star) possessed British papers but had changed from American ownership only two weeks earlier. When Martabans captain failed to produce a sworn certificate stating that the papers were authentic, Semmes burned the ship. This action incensed the British and would ultimately force Semmes to sail for France. Re-crossing the Indian Ocean, Alabama departed Cape Town on March 25, 1864. Finding little in the way of Union shipping, Alabama made its final two captures in late April in the form of Rockingham and Tycoon. Though additional ships were sighted, the raiders fouled bottom and aging machinery allowed the potential prey to out-run the once-swift Alabama. Reaching Cherbourg on June 11, Semmes entered the harbor. This proved a poor choice as the only dry docks in the city belonged to the French Navy whereas La Havre possessed privately-owned facilities. Requesting use of the dry docks, Semmes was informed that it required the permission of Emperor Napoleon III who was on vacation. The situation was made worse by the fact that the Union ambassador in Paris immediately alerted all Union naval vessels in Europe as to Alabamas location. CSS Alabama - The Final Fight Among those who received word was Captain John A. Winslow of USS (7). Having been banished to a European command by Secretary of Navy Gideon Welles for making critical comments after the 1862 Second Battle of Manassas, Winslow quickly got his ship underway from the Scheldt and steamed south. Reaching Cherbourg on June 14, he entered the harbor and circled the Confederate ship before departing. Careful to respect French territorial waters, Winslow began patrolling outside of the harbor to prevent the raiders escape as well as prepared Kearsarge for battle by tricing chain cable over the vital areas of the ships sides. Unable to secure permission to use the dry docks, Semmes faced a difficult choice. The longer he remained in port, the greater the Union opposition would likely become and the chances increased that the French would prevent his departure. As a result, after issuing a challenge to Winslow, Semmes emerged with his ship on June 19. Escorted by the French ironclad frigate Couronne and the British yacht Deerhound, Semmes approached the limit of French territorial waters. Battered from its long cruise and with its store of powder in poor condition, Alabama entered the battle at a disadvantage. As the two vessels neared, Semmes opened fire first, while Winslow held Kearsarges guns until the ships were only 1,000 yards apart. As the fight continued, both ships sailed on circular courses seeking to gain an advantage over the other. Though Alabama hit the Union vessel several times, the poor condition of its powder showed as several shells, including one that hit Kearsarges sternpost, failed to detonate. Kearsarge faired better as its rounds hit with telling effect. An hour after the battle began, Kearsarges guns had reduced the Confederacys greatest raider to a burning wreck. With his ship sinking, Semmes struck his colors and requested help. Sending boats, Kearsarge managed to rescue much of Alabamas crew, though Semmes was able to escape aboard Deerhound. CSS Alabama - Aftermath The Confederacys top performing commerce raider, Alabama claimed sixty-five prizes which were valued at a total of $6 million. Hugely successful in disrupting Union commerce and inflating insurance rates, Alabamas cruise led to the use of additional raiders such as CSS Shenandoah. As many Confederate raiders, such as Alabama, CSS Florida, and Shenandoah, had been built in Britain with the British governments knowledge that the ships were destined for the Confederacy, the US Government pursued monetary damages after the war. Known as the Alabama Claims, the issue caused a diplomatic crisis that was finally resolved by the formation of a twelve-man committee which ultimately awarded damages of $15.5 million in 1872.

Data analysis task Assignment Example | Topics and Well Written Essays - 500 words

Data analysis task - Assignment Example Both of the genes contribute fragments to the gel that have been sectioned by the enzyme. These portions have complementary bases to the probe, thus forming more bands. Simply, there is a copy of R and r portions in the heterozygote. The lighter bands represent homozygote state. That is, there is less DNA to map. This can only imply that half the DNA is present. 7) When the blot was probed at high stringency with a probe made with DNA that flanks the R gene (as seen in Figure 1) a smear typical of thousands of hybridising bands was seen. How could this be explained? 8) The turnaround time for Southern Blot analysis is typically around 10 days. Now that you have identified the region in which the mutation lies explain with detail how a faster test could be designed? Now that the portion has been identified, a faster test would only need one to cut the DNA at the specific location. After that has been done, the cut portion is denatured, pre hybridized and transferred to a gel block. Alternatively, it could be run through PCR and analysed using an electronic DNA

Apple Case Analysis Essay Example | Topics and Well Written Essays - 2000 words

Apple Case Analysis - Essay Example There was no surprise to see people standing in long queues eagerly anticipating the launch of ipad3, almost everyone wanted to get their hands on the newest gadget launched by Apple again underlining their dominance and global reach. Apple is arguably the best brand in the world because they have spent a lot of money on innovation and they have achieved their objectives in the recent past of making their gadgets better than other similar gadgets available in the market. Steve Jobs always wanted to make a computer which was easy to use and he managed to do it, Apple II was launched in the year 1978. It was an easy to use computer, it is said that the launch of Apple II completely revolutionized the computing industry. Apple also became a leader after the launch of Apple II in 1978. Competitive Position Apple’s dominance was challenged by IBM, IBM entered the fray in the year 1981, Apple found their newest rivals in IBM. There was a major difference between the systems produced by the two companies, Apple’s computer was a prototype and could not be cloned on the contrary IBM’s system could be cloned by others very easily. IBM heavily relied on Intel to supply processors but that was not the case with Apple. IBM’s entry into the market did not affect Apple’s revenue but IBM took away the market share from Apple to a certain extent and Apple had their eyes set on winning the market share once again and restoring normalcy. A significant changed occurred in the year 1984; a very young Steve Jobs presented Macintosh to the whole world in an endeavor to win back their lost market share. The technical elegance and the design of the new Macintosh, was captivating beyond imagination but when it came to performance the Macintosh disappointed its users. It was really slow and because of these lags it did not sell as expected by the honchos at Apple. Between 1983 and 1984 Apple had a torrid time, net income of the company fell by 17% and s uddenly the company was in crisis. Steve Jobs was removed from his post after these series of setbacks, John Sculley was at the helm back them. He was the same man who reinvigorated Pepsi and fought successfully against Coca Cola to gain dominance. Sculley worked on graphics and designs and knew that these were the two key elements that could take Apple to where it originally belongs. Desktop publishing was another key area which Sculley targeted and Apple all of a sudden started producing systems which were best when it came to desktop publishing. Major Competitive Advantages As discussed earlier Apple’s design and elegance were two factors which gave it an edge over other companies but these two factors were anything but enough to propel the company to the very top. Several other competitive changes were made by Sculley during his time at the helm, his tie-up with Aldus which is now known as Adobe was a great move for Apple and it restored much needed stability in the compa ny, products designed by Aldus were used for desktop publishing and the same made Apple one of the best in the world once again post the Steve Jobs era. The Macintosh started selling like hotcakes once the products made by Aldus were used in the Macintosh, Apple recorded record sales of the Macintosh and that was when Apple regained its prominence. Accessories like laser printers were also sold by Apple and the same had unmatched capabilities and this is why

Censent and Research (CASE) - Essay Example The bone marrows in this case are unable to synthesize blood cells that are healthy (Leonard, 1998, p. 15). The abnormal white cells produced extend to other body parts causing damage. Chronic leukemia is the type of leukemia diagnosis that progresses slowly. It can be identified as the early stages since its impact to the body is not as intense as those of acute leukemia but can not be under estimated since it is equally dangerous. In chronic leukemia, the abnormal white cells are generated at a faster rate than the white cells. As time goes by, the abnormal white cells over power the normal white cells. The treatment approaches vary depending on the stage of the disease. The kind of patient may also make the treatment approach vary from one patient to another. Children are very delicate patient when it comes to leukemia disease. Most leukemia patients who are below the age of 15years experience the early stages of the disease. Leukemia becomes intense from the age of 15years and above. When dealing with young patients such as children with leukemia, the people close to them are supposed to be aware of the changes that might be caused by the medical condition of these patients. Most parents may tend to ask ‘what kind of changes is their child suffering from leukemia likely to experience?’The changes may be physical or mental. Leukemia patients experience negative emotions such as sadness and fear during the advanced stages of the medical conditions. During these moments, the family members or the people close to the patient need to give a close attention to the patient in order to help him or her deal with the changes efficiently without causing more harm to his or her body that my worsen the condition (Peacock, 2000, p. 37).
