Impact of Computers on Day-to-day Life - Essay Example Social networking is another area in which computers have changed peoples’ lifestyle. Many of the offline businesses were transformed to online businesses because of the abilities of computers in promoting e-businesses or e-commerce. Weather forecasting and global positioning systems are some of the other areas in which computers are used extensively nowadays. This paper analyses the impact of computers in day-to-day life. Business is one area, which gained a lot because of the introduction of computers. It should be noted that instant communication is made possible because of the introduction of computers and internet. Business always likes to have the exchange of information as quickly as possible in order to make sound decisions. Earlier, fax messages and telephonic conversations were used for business communications along with telephones. However, these technologies had many limitations in communicating the ideas properly between the stakeholders of business. The introduct ion of computers helped business people to present their ideas clearly to others. Computer controlled machinery is used a lot in many of the manufacturing units nowadays. This machinery has the ability to do provisioned work more efficiently than humans do. According to new figures released by the United States Department of Commerce, e-Commerce Sales accounted for 2.4% of all sales in the fourth quarter of 2005, up from 2.3% the previous quarter. Total fourth quarter e-commerce revenues came to a seasonally adjusted $22.94 billion. For all of 2005, e-commerce sales rose by 24.6% according to information from the U.S. Census Stats (Internet World Stats News) Earlier business activities were taking place only in the real world. Introduction of computers opened another channel for business in the virtual world. Many of the recent studies have shown that offline or virtual world business is going to surpass real world business in the near future. Computers have helped business people w ith another channel to market and provide their services. Education is another sector in which computers proved their worth. For effective transfer of knowledge from the teacher to students, computers are extensively used in classrooms at present. Computer assisted technologies are helping both the students and teachers to polish their ideas. For example, teachers can take notes from the internet before presenting a particular topic in the class. In the same way, exceptional students who are not satisfied with the classroom knowledge can look on the internet to get more knowledge. IPads and tablet PC’s are helping students to get rid of the inconvenience of carrying textbooks and notebooks to the classes. Teachers can assess the progress of the students with the help of computer software. In short, computers can help in the enhancement of quality of education. Social networking is the third segment in which computers are influencing people in their day-to-day life. The popula rity of Facebook, Google Plus, MySpace, Twitter etc clearly indicate the importance of computers in daily life. It should be noted that millions of people from all over the world are spending a substantial period of time in social networks nowadays. Apart from ordinary people, even business people, marketers, job seekers, etc are also interested in using social networks now. The concept of social networking would not be in place if the computer related technologies were not there. As mentioned

Cell biology &genetics - lab report - Essay Example The objective of this experiment is to observe the several stages of mitosis in an onion root cell through a light microscope. Onion root tips were prepared by washing in clean water then rinsing with distilled water. After this, a root tip section about 2mm in thickness was cut from the root tip using a sterilized scalpel; this was then placed on a glass slide with a drop of distilled water on it to avoid dehydration. Afterwards the root tip section was them fixed in Carnoy’s fluid inside a Bijou bottle for about 10 minutes. After fixing, the section was then transferred to a Petri dish containing distilled water where it was rinsed for approximately 2 minutes. After rinsing, the root tip section was then placed inside a bijou bottle containing 1 ml of 1M HCl and incubated at about 60ï‚ °C for about 5 minutes. The contents of the tube were then poured into a Petri dish and the root tip carefully picked out using forceps and transferred into another Bijou bottle containing aceto-orcein which was then left in a dark chamber for about 10 minutes. The bottle was then removed from the chamber and the root tip carefully removed using forceps and placed on a slide on which a drop of 45% acetic acid had been placed, this was then covered with a cover slip. By this time the root tip section was already well softened and stained; the tip was then squashed by slightly tapping on the cover slip with a pencil until it was evenly spread out under the cover slip as a pink mass. The glass slide with the root tip ready for observation on the microscope was then transferred to a light microscope and viewed at x400 magnification strength. Photographs of the cells undergoing mitosis were then taken and drawings made of the various stages of mitosis. It was observed in the experiment that the cell division process assumed all the four stages shown in the images above and that the staining clearly revealed the features of all the four stages it takes for a cell

IT systems failure Essay Example | Topics and Well Written Essays - 1000 words

IT systems failure - Essay Example The procurement manager crossed the limits by giving warnings and transferring the employees to other departments. The abovementioned problem has been identified and categorized as the cultural dimension problem among the technical, cultural and managerial dimensions of the problems (Feghali & Zbib, 2007). Being a project manager, I would recommend to not only involve the end-users in the development of the E-Pro system but also to earn their confidence; to do this is a desperate need. As the end-users are always helpful in identifying the issues and problems of the existing processes, they can provide valuable input for solving the identified problems. The end-users can also help review the prototypes and provide feedback, which needs to be incorporated before the final deployment of the IT systems. Moreover, the end-users should also be involved in the testing phase of the project. This leads to a conclusion that the effective end-users involvement not only saves money but also mak es the IT project successful (Kastner, 2010). Recommendation II The second problem that I have identified in the given case of E-Pro system development is the mismanagement of the key stakeholders. The IT and procurement manager has mismanaged not only the external stakeholders but also the internal stakeholders, who have a direct impact on the development of the system. ... In the case, the suppliers had not been informed about the development of the E-Pro system before the project was started. When the procurement manager informed the suppliers in the middle of the project, they had a number of concerns regarding the development of the E-Pro system; still, they have been ignored by the procurement manager. Due to this behaviour of the procurement manager, the suppliers became a hurdle in the success of the project. Keeping in view the abovementioned fact and being a project manager, I would recommend that all the stakeholders be informed about the situation in advance. It is always good to develop consensus in early stages of the project; it helps reduce the probability of disagreements or conflicts, which are harmful for the successful implementation of the project. Recommendation III I would recommend that superiors be always informed about the progress of the project as well as the issues that are being faced in the project. According to the case st udy, the IT and procurement manager did not inform the managing director of the company about the then current state of the E-Pro project. Initially, they did not inform the managing director regarding the lack of confidence and conflicts with the employees or end users of the developing system. And then nobody informed the managing director that even the suppliers were not happy and had a few concerns regarding the development of the E-Pro system. Eventually, when the managing director was informed, the situation had already been out of control and the company needed to abandon the project. It has been identified as â€Å"lack of information flows among all stakeholders involved† and has been categorized as a cultural

Travel Let People Be More Understanding Essay Example for Free

Travel Let People Be More Understanding Essay Traveling is an excellent opportunity to go beyond the boundaries of own country. International tourism enables to open new corners of the world and get familiar with unique unknown cultures, which are multiple on the Universe. Yet, what is more important, traveling allows people not to just enlarge the physical limits of regular existence, but it also widens the outlook and even shapes the existing values by showing how others live and perceive the world.   Ã‚   There exist different types of international tourism – leisure tourism, business travel, medical travel, and historical travel. Leisure travel allows people to go to different usually exotic places (Africa, South East Asia etc.) and have a rest there enjoying the seaside, the sun, beautiful beaches. Business travel supposes that a person visits other countries on business trips. Nowadays, medical traveling is becoming more and more popular. People go abroad to cure from certain diseases or simply enhance there health. Finally, the main purpose of historical tourism is to see the historical heritage of the country. Such a trip supposes multiple excursions to different places of interest of the particular country. However, no matter what is the main purpose of traveling abroad, visiting other country opens new boundaries before the person, which reflect in the different things.   Ã‚   First of all, trip abroad enables people to get familiar with new things – geography, culture, history of the visiting place. This upraises the educational level of the person and enhances self-consciousness of him. For example, we all know that Egypt is famous for its pyramids that are thousands years old. Those pyramids are the foremost glory and distinction of the country. However, not all knows how much effort and human lives were put into those constructions. Only seeing those giants own self, it is possible to understand the real value of human life. Seeing those pyramids, one can realize that his life is nothing compared to thousands year old stone. Such important revelation very often makes people reflect on what they do in their life and how much time they have on this world to do something valuable unless they go away. Another relevant example is Turkey. We used to think that Turkey is a great resort with its wonderful beaches and sea. Yet, on coming to Turkey one gets a chance to see exciting historical places, cause Turkey is the place where there are traces of all three major religions – Islam, Christianity, and Judaism. Thus, we can see that international tourism helps to raise educational level and the level of self-consciousness of a person.   Ã‚   Secondly, traveling enables to form own objective point of view independent of those, which are based on TV programs, journal and newspaper articles, radio broadcasts etc. For instance, Pico Iyer (2002) assures that Arab population is not as evil as American officials portray it. All the media has been stating and convincing other countries that Arabs are terrorist and Americans have to fear them. Moreover, special campaign was even launch to assure that the war against terrorist was the only mean to save and help the nations where this terrorism originated. Yet, as author tells, he was greatly surprised visiting   Bolivia, Vietnam, India and other countries to hear that the those nations are actually against American’s decision to initiate the war. Being â€Å"locked† within the borders of one territory, it is impossible to get a clear picture and understand how others perceive you nation and your country, cause mass media might interpret the events and the opinions according to its own benefit. Thus, only visiting other countries, it is possible to get an objective panorama of everything that is going on in the world. Giving the example of Iyer, international traveling enables Americans to tell other nations that USA is not an evil.   Ã‚   To the third, traveling enables to get rid of certain prejudices that might exist in society in the form of â€Å"common opinion†. Again, as Iyer (2002) states, when he took his mother to Syria, she was very pleasantly surprised to realize that this country was much friendlier, much cleaner and more well-off that she previously thought of. It happens very often when we derive our opinion from certain common sources and form a stereotype and prejudice concerning the thing. Thus, traveling destroys stereotypes and creates more space for us to let in other opinions, views, thoughts. Ultimately, it helps us to be more receptive, more attentive and more tolerant to other cultures, to other opinions, which can be different from ours.   Ã‚   Finally, traveling influences the behavior of people. When one goes to China or Japan and gets exposed to this unique special culture, get to know the beliefs and habits of those people, there is always a temptation to follow the example. Watching the very ascetic Japanese man who can sleep on the mattress and eat only seafood, the thought about the excessive exuberance and its unimportance arises itself. Thus, the habit of living luxuriously might change into a habit of living according to the need. When observing how brave and enduring the peoples of Latin America are, the desire of being like them, fighting to the last comes instantly. Thus, traveling is able to change the whole behavior of a person.   Ã‚   To   conclude, it is important to say that traveling doesn’t simply allow to go beyond the border of the country of residence, but it also allows to go far beyond the limits of traditional thinking and mind. Exposing one to different cultures, vies, beliefs, traveling changes people’s values, behavior, destroy stereotypes and widens general outlook. The summarized benefits that traveling gives are the following: Deeper and wider outlook – new knowledge, new insights; Possibility to form personal objective rather than subjective opinion concerning different things based on own experience; Destruction of prejudices and ability to become more flexible and receptive; Gain of new patterns of behavior, new personal qualities.       References Butler R. â€Å"Contemporary Issues in Tourism Development† Routledge, London, 1999- Cooper C. â€Å"Tourism at the Age of Globalization† Routledge, London, 2001 Pico Iyer â€Å"The necessity of Travel† 2002.

Free Essays - Angela’s Ashes :: Ashes

Angela’s Ashes   In Frank McCourt’s memoir Angela’s Ashes, the connection between tone, syntax, and point of view combine to create an effective balance of humor and pathos.   This is shown through the perspective of little Frank McCourt.   Sometimes it is human nature to try to make a tragedy seem better than it is in order to go on with our lives.   Frank’s struggle to make his situation as a poor, Catholic, Irish boy more bearable, is demonstrated through the positive tone, powerful syntax and childlike point of view. Humor and pathos come together when Frank steals bananas from the Italian, but later the same Italian gives him a bag of fruit.   Frank knows that he can’t buy the bananas and he knows also the Italian won’t give them away seen when Frank says; â€Å" Italians are not known for giving away bananas† (p.35).   We can see the humor in the theft as the â€Å" twins slobber and chew and spread bananas over their faces, their hair, their clothes† (p.36).   The tragedy is that the McCourt kids are poor and have to resort to begging and stealing to survive.   When the author uses such words such as â€Å"slobber† (p.36), â€Å"little buddas† (p.36), he is trying to make an intolerable situation more bearable and enjoyable to the reader.   When the McCourts are at their new home, two weeks before Christmas, the children come home and find the whole downstairs flooded.   They decide that they will stay up stairs, which they call â€Å"Italy† (p.118), and the downstairs â€Å"Ireland† (p.118).   The humor in this tragedy is the house is so run down that water leaks in and floods the bottom.   Instead of suffering and complaining about the house they move upstairs and make the best out of it and try to live normally.   The reader should find this funny from the way the family talks about it, they try to make the situation more bearable by adding a sense of humor.   They leave the â€Å"Pope† (p.118) downstairs because Angela doesn’t â€Å" want him on the wall glaring at me in the bed† (p.118).   The syntax used is to make the reader feel pity for the family when the whole downstairs is flooded but also the author wants to make the reader laugh when the family decides to lighten the situation by creating an adventurous illusion.   One of the funnier moments is the scene where Frank pukes up the host and his Grandmother says she â€Å" has God in her backyard† (p.

To Appreciate the Nature of Life We Must First Understand the Cell

Life itself is amazing. It surrounds us on a daily basis from the ants in our window seal, the squirrels on the power line, to the bacteria we all have in our mouths and on our bodies. Life is indeed a gift. Every life that comes into this world is made up of cells, life of humans, plants, and animals. I know that to understand the nature of life we must first comprehend the cell, its parts, and organelles. There are two different types of cells, including prokaryotic and eukaryotic. Living bacteria is an example of something that contains prokaryotic cells.Eukaryotic cells are in just about everything, all humans and all animals. I must say that the eukaryotic cell is way more complex than the prokaryotic. A prokaryotic cell does not even hold a nucleus, which is the brain of the eukaryotic cells. Human and animals cells cannot be developed without prokaryotic cells. Even though these two different types of cells are very different they also are somewhat similar. Both contain riboso mes, cell membranes, and cytoplasm. Plant cells are eukaryotic cells but there are items that definitely set them apart. Cell walls, chlorophyll, and vacuoles are difference between the two.By plant cells having these different organelles, they function in a unique order. Each organelle in the cell do different task. Supporting all organelles in the cell is the cytoplasm. Cytoskeleton maintains the shape and gives it strength. The nucleus is a cell’s brain and operating system. The mitochondrion develops energy through cellular respiration. Ribosomes produce protein, while the nucleolus is what makes ribosomes. The vacuole is the largest organelle and it stores food, wastes, and water. The cell wall which is in all cells except animals, protect the cell and allows elements such as water, oxygen, and carbon dioxide to enter.Endoplasmic reticulum is what carries materials through the cell. Lysosomes are what break down large food molecules into smaller ones. Using energy from t he sun to produce glucose is the chloroplast (which can only be found in plant and algae). Cells make up life. We cannot live or operate without them. Each individual cell is like groups of workers that work together. Without the nucleolus which makes the ribosomes, we would not have any protein. And without protein, we as humans could not be healthy. Humans need cells and all their many organelles. Without cells, there is no life.
