The Issue with Issuing Laptops essays

The Issue with Issuing Laptops essays Supplying students across Cobb County with laptops is a bad idea. There is a lot of money going towards this leap in technology. There are some good things about them. Firstly, learning would become more interactive. Secondly, some students would make better grades. There would be more doors opened for learning. Students with problems in their shoulders and backs wouldnt kill themselves lugging books around all day. Now, think for a second about how much money is going towards this project. Now think about that kid who kicked a fifty dollar textbook down the hallway because he was to lazy to pick it up after he dropped it. Who is to say this wont happen to the laptops? What about when books fall off lunch tables? The laptops would be crushed. And the repair rates would be enormous. Remember the money Cobb is proposing to pay to buy them in the first place? Multiply that by two when the replacement and repairing comes into play. Cheating would reach an all time high in the classroom. It would be very easy for a student to sign onto the internet network and email friends answers to tests and share essay topics. That is partly why the students would receive better grades. They would have all the answers delivered to them by other students classrooms away or even a few desks away. It would be almost as bad as issuing each student a cell phone capable of taking pictures and texting across the building. It would be infinitely harder to judge class participation. Teachers would not be able to tell who was doing what unless he or she walked around the classroom to monitor every student individually. The internet connection would be horrible. The internet is a very useful tool in learning, but so many computers would be entering the system at the same time that the server would most likely overload. It would be virtually impossible to keep it running. The issue is that laptops can help, but they can also b...

Modeling DNA - Structure, Function and Replication

Modeling DNA - Structure, Function and Replication Constructing DNA models is a great way to learn about DNA structure, function, and replication. DNA models are representations of the structure of DNA. These representations can be physical models created from almost any type of material or they can be computer generated models. DNA Models: Background Information DNA stands for deoxyribonucleic acid. It is housed within the nucleus of our cells and contains the genetic information for the reproduction of life. The structure of DNA was discovered by James Watson and Francis Crick in the 1950s. DNA is a type of macromolecule known as a nucleic acid. It is shaped like a twisted double helix and is composed of long strands of alternating sugars and phosphate groups, as well as nitrogenous bases (adenine, thymine, guanine and cytosine). DNA controls cellular activity by coding for the production of enzymes and proteins. The information in DNA is not directly converted into proteins, but must first be copied into RNA in a process called transcription.​ DNA Model Ideas DNA models can be constructed from almost anything including candy, paper, and even jewelry. An important thing to remember when constructing your model is to identify the components you will use to represent the nucleotide bases, sugar molecule, and phosphate molecule. When connecting the nucleotide base pairs be sure to connect the ones that pair naturally in DNA. For example, adenine pairs with thymine and cytosine pairs with guanine. Here are some excellent activities for constructing DNA models: How to Make a DNA Model Using CandyCardboard DNA ModelsDNA Jewelry ModelKNEX DNA Models DNA Models: Science Projects For those interested in using DNA models for science fair projects, remember that simply constructing a model is not an experiment. Models may be used, however, to enhance your project.

Epidemiologic Investigation Essay Example | Topics and Well Written Essays - 6000 words

Epidemiologic Investigation - Essay Example In the context of this project, the disease agent is a particular strain of E. coli that is well regarded as a food borne pathogen responsible for an infectious diarrheal disease. By definition, the characterization of the disease is intimately related to characterization of the agent that initiates or perpetuates the disease process. The E. coli talked about here is an enterotoxigenic strain of E. coli, which is a biological agent which exhibits certain host-related biological properties such as infectivity, pathogenicity, and virulence. Since an individual almost always contract a disease from his environment, when an epidemic of infectious disease occurs, the cause usually lies in the environment. Therefore, in any specific population, in order to be able to prevent outbreak of any disease state and to be able to intervene, the conditions prevailing any health-related event or state can be investigated, and appropriate measures can be taken to apply the findings of such studies for controlling the health problems preemptively. FoodNet or the Food Borne Diseases Active Surveillance Network was developed by CDC in the Emerging Infections Program. In this program, data are collected 10 US states in relation to the disease burden caused by Escherichia coli 0157:H7 strains that are known to be transmitted through food. This program quantifies and monitors the incidence of these infections by conducting active surveillance for laboratory-diagnosed illness. This epidemiologic event has great implications in public health. From the epidemiologic point of view, this is important since FoodNet quantifies and monitors these infections by conducting active population-based surveillance for laboratory-confirmed illness. The epidemiologic methods are used as surveillance tools, and these essentially scrutinize continuously the factors that would have determined the occurrence and distribution of this disease to be able to effectively control and prevent the disease. These essentially include collection, analysis, inter pretation, and distribution of relevant data for action. Escherichia coli is an emerging cause of food borne illness in the United States. Although most of these illnesses are mild, severe infections and serious life-threatening infections do occur. This has posed challenges to public health and public health administrations since there is change in the newly identified strains of the pathogens. With that, novel vehicles of transmission, changes in food production, and an apparent decline in food safety awareness might have aggravated the problems leading to these illnesses. There are several types of national surveillance systems for diseases that are food borne. These epidemiologic tools include outbreak surveillance, passive laboratory based surveillance, and active surveillance. Communicable diseases may be transmitted from the reservoir or the source of infection to the susceptible individuals in many different ways depending on the infectious agent, portal of entry, and the local ecological conditions. It is important to note that mu ch of the data about the vehicles and modes of transmission of these food borne diseases come from epidemiologic investigations of the outbreaks. From the public health point of view, the

Issues Faced by Operations Managers Essay Example | Topics and Well Written Essays - 1250 words

Issues Faced by Operations Managers - Essay Example Shortage of funds in financial market can create a problem for managers because supply of money in company leads to different financial activities. Continuous supply is very important for any company to operate. Managers also need to know that what their competitors are doing in the industry. They can't ignore competition around them in this dynamic world. Managers need to be informed that what they are doing in terms of Product development, Pricing, Marketing strategies and many more things. Any type of activity that the competitors do can create lots of problem for the managers. Every organization has an aim to be Global. Managers need to face many difficult situations when they are in foreign countries. They need to tackle certain factors for success when they are abroad. That includes Legal/Political Environment, Economic Environment and Cultural Environment. While going Global managers need to understand the Political and Legal uncertainties in the country they are doing their business. They should be aware of the Specific Legal laws of that country because if they don't know the Legal procedures of that country it can create many problems for them. Many countries have a history of unstable governments therefore managers face dramatically greater uncertainty as a result of political instability. For example the goal of one government is to nationalize the important sectors of the country where as the goal of the other government is to have free enterprises to promote free market economy. Economic environment can also affect manager's decision. The three most important factors in affecting manager decision are Fluctuating currency exchange rates, Inflation Rate and Tax policies. If the country has a high inflation rate in which they are operating can result in high productivity cost which can ultimately decrease their profits. Tax policies are the most concerning for managers. If tax policies are restrictive managers can face challenging situations. Managers need exact information of tax rules so that they can overcome with all the tax obligations.Managers also need to understand the culture of the country in which they are operating. Different countries have different cultures and managers must know they difference of each culture. This is very important factor for managers to take care of, because if they fail to understand the cultural values of that country they can't serve their products and services to the people of that country. For example if a company who is manufacturing Alcohol and is operating in USA and then they open a branch of their company in Saudia Arabia, But as Saudia Arabia is an Islamic State they can't sell the Alcohol in that country because they cultural and religious values doesn't allow them to drink, that can create huge problem for the managers of that company. SOCIAL RESPONSIBILITY: Today's organizations are moving towards social responsibility. Managers have to be careful while going for socially responsible because being socially responsi

Rebuttal Essay on Needed: A License to Drink -- Alcohol Drinking Essay

Rebuttal Essay on â€Å"Needed: A License to Drink† â€Å"Needed: A License to Drink† is an essay written by Mike Brake. In this essay, Brake explains why he thinks people need a license to drink. He has had family members die from alcohol related events and believes they might still be alive if a license was required to drink. Alcohol is related to many deaths and alcoholism is a disease that affects many people. â€Å"It causes more than 19,000 auto fatalities each year, it is responsible for more than a third of deaths from drowning and fire† (Brake135). Brake mentions that doctors have to report certain sexually transmitted diseases. He think they should have to report alcoholism as well. Also, licenses for hunting, guns, and driving are required, so Brake believes a license for drinking should also be required. Brake believes, â€Å"licensing would act as a screen—preventing a small percentage of the misery up-front† (136). If there was a way to carry out his plan successfully, I wo uld agree with his essay. However, it would be impossible to use Brake’s licensing plan and expect it to be successful. Brakes plan has flaws that have failed before. Doctors should not have to report alcoholism, and licenses would not prevent alcoholics from getting alcohol. Brake’s Plan First, people who want a license would have to study a written manual with facts about alcohol and the law (Brake 136). Next, they would have to be able to pass a written test. If someone gets in alcohol related trouble, the license would be taken away. If they do not have a license, they will have to receive treatment along with attending Alcoholics Anonymous (136). Problems with the Plan If everyone was willing to... ...etting it. Conclusion Doctors should not have to report alcoholism because it is different from other diseases. Also, licenses would not prevent people from drinking because underage people and those without a license would still have ways to acquire alcohol. Brake’s plan would be great if everyone was to abide by it, but unfortunately it would be almost undoubtedly impossible to create a plan like his and expect it to be successful.

Baskerville Murder Essay

Murder mystery tales are among the most popular book genre. Murder mysteries will usually consist of an unknown murder that killed a significant character. The detective has to decide among many suspects with clues he or she found in the course of the book. Authors typically write books of this genre because they give the reader a feeling of suspense and confusion as they read the story. It keeps them guessing and switching their opinions as new facts are read. In The Hound of the Baskervilles by Arthur Conan Doyle, protagonists, Sherlock Holmes and Dr. Watson meet many people involved while trying to find the murderer of Sir Charles Baskerville, as said to be a mythical demon hound. Although there are many subjects in the case of the murder, Dr. Mortimer, The Barrymores, Jack Stapleton, and Roger Baskerville. Dr. James Mortimer is a medical practitioner. He is described as tall, thin, and good-natured with rather eccentric habits. He is the first suspect Holmes and Watson meet and the person to tell them about the case. He is possibly the murderer because he was in charge of Sir Charles will when he died. He could of manipulated the will to his own use. By killing Sir Charles the will follows whatever he would of made it. He challenges Holmes in the intro of the story to solve the case. He also owns a dog as shown on the carriage when him, Henry and Watson were headed to Baskerville Hall and discovered by the bite marks of his cane. Its possible that Mortimer could of used his dog and disguised him as the hound to scare Charles at a distance. He is also a close acquaintance to the Baskervilles so he knows a lot about the family that he could of used fro his plans. His information on Sir Charles’ condition at the time is explained when Mortimer said, â€Å"Within the last few month s it became increasingly plain to me that Sir Charles’s nervous system was strained to the breaking point† (Doyle, 43). With this information he could had literally â€Å"scared him to death† with any means that would relate to the hound’s curse. Mr. and Mrs. Barrymore are servants to Sir Charles and Henry. Mr. Barrymore is described as tall, thin and has a black beard. They are very close to the Baskervilles since their family served them for generations. Their motives could be after their wealth or maybe on the inside they are sick of serving them. The hound of legends could have been the Barrymores who served Hugo Baskerville and they were tired of a life of servitude. This hound could of went on from generation to generation. Supposedly, Holmes and Watson first seen Mr. Barrymore when they were chasing a man in a van and the driver described him as a short man with a black beard. When Watson and Henry arrive at Baskerville Hall, Mr. Barrymore says he and his wife would leave the hall soon because of Charles’ death and its too painful of them. As for Mrs. Barrymore, Watson says during the first night, â€Å"And then suddenly, in the very dead of the night, there came a sound to my ears†¦ It was the sob of a wo man, the muffled, strangling gasp of one who is torn by an uncontrollable sorrow† (Doyle, 159). The crying indeed comes from Mrs. Barrymore, which could have been caused, as Watson predicts, a haunting memory. Its possible the letter they received could also have something to do with the case. Jack Stapleton is a short man and a naturalist. He lives in the outskirts away from the other neighbors and the Baskerville Hall. He lives with his sister, Beryl and two servants. He became a suspect because Mortimer told Holmes and Watson that he knows the ins and outs of the moor. Watson first meets him when he came up to Watson and began a conversation. Oddly enough, he was interested in what Holmes and Watson thinks of the case and murder so far. After a few days with Stapleton, Watson believes something is not right about Stapleton and that he is masking his true colors to him. His motives could be that he is after the fortune of the family and only wants to be rich. When Beryl came to Stapleton and Watson while they finished their conversation, she said, â€Å"Go back! Go straight back to London, instantly†¦ Go away from this place at all costs! Hush, my brother is coming! Not a word of what I have said† (Doyle, 183). Thinking Watson was Henry, se gave him a warning , but said not to tell Stapleton. She later explains that he doesn’t want Henry to leave because the people need someone, but Watson is well aware she is hiding something. If Stapleton was the killer, he must be a master of disguise. When the driver described the man as short and with a black beard, Stapleton could of easily put on a fake beard and mislead the duo. He would also have access to Henry’s hotel room and take his shoes and he could of disguised himself as the hound. Roger Baskerville was the â€Å"black sheep† of the family when Hugo Baskerville was the owner. He is the son of Hugo and the brother of John. Mortimer states that he escaped to Latin America because he was an outcast and disgrace to the family. Interestingly enough, he never states if he died while there. Roger could of came back for revenge and would kill every Baskerville so he would be the only heir left. If he did survive and he came back, he is hiding somewhere from the people. What’s difficult is that anyone could be him because its unknown what he looks like. As Mortimer and Henry travel to Baskerville Hall, they were stopped and Perkins told them, â€Å"There’s a convict escaped form Princetown, sir. He’s been out for three days now, and the warders every road an every station, but they’re had no sight of him yet† (Doyle, 146). Roger could be the convict, Selden, and killed Charles before or after he was thrown in prison. Mortimer, the Barrymores, Stapleton and Roger Baskerville are the most likely suspects to the killer. Out of the four Stapleton could be the killer because he is more mysterious than the others and the fact he knows the moor makes him the prime suspect. Overall, mystery books are interesting because as the reader continues the story, his or her opinion will keep changing and gives the reader the suspense of who the person is. The Hound of the Baskervilles is one of many excellent mystery novels.

The Life of Stephen Hawking Essay - 576 Words

Born January 8, 1942 in Oxford England, Stephen Hawking was born -as some say- into a family of intellects. Stephens’s father, Frank hawking, studied at Oxford University as a medical researcher – while mother, Isobel Hawking, was one of the first women to attend the university in the 1930’s (a time period when not many women considered college). The two raised four children together, Stephen being the oldest. While Stephens’s father would have had the eldest children study medicine at university, it was apparent from an early age that Stephen and his siblings had taken to the stars. In his prime educational years, it was seen that Stephen was bright but was considered to be a poor student. He was more interested in games and fun,†¦show more content†¦It was due to this discovery in the world of physics and science that Hawking’s career would boost into publishing and into teaching opportunities. Hawking is also renowned for his theories that would introduce the world to different views on the universe. One of which he shares with Jim Hartle, on the boundaries of the universe. It was in 1983 that Hawking and Hartle came together using quantum mechanics, and Einstein’s theory of General Relativity to introduce the paradoxical concept of the universe being a contained entity – but with no boundaries. Hawking said to think of the concept, in which you are viewing the universe as the surface of the earth. With the earth being a sphere, you know that by either direction that you travel – there are no corners – no endings or boundaries. However, one of the major differences between the earth and the universe – is that the earth’s surface is two dimensional (though the earth itself is three) and that the universe is four dimensional. Hawking explains the concept further with space-time. Space-time here works like the lines of latitude on a globe. The North Pole (the beginning of the universe) going south, means the circumferences get bigger until the lines go beyond the equator; in which they would get smaller. This means that the universe is finite in space-time; thus explaining the paradoxical concept of the universe being a contained entity with no boundaries.
