Meeting for business ideas - Coursework Example Smartphones and tablets are the devices that make the most sales, according to various business reports. This initiated the idea to create a mobile application known as SecureIT, to protect and promote IT security awareness online users in the course of their transactions. Different organizations are aware of the online security threats. They are embracing the relevant technology to mitigate the risks. Online hackers have the ability to capture the information that is in transit from servers to users. They have the ability to disrupt or manipulate the information, creating a negative impact to a given organization. In addition, the attackers have the ability to steal the data and deface web pages (Curtin, 2002). Through the SecureIt application, users could require the creation of an account that could enable them to access a feature that has the ability to encrypt data. The application has the capability to trace the geographical location of the attackers through their Internet Prot ocol address, in addition to their address books. Once the application collects the information, it informs the servers and the clients on the potential risks that exist. The other online security challenge relates to the faults and miscommunication between the servers and the clients. The server could fail in the screening of the clients’ data and the attackers could take advantage through their software that runs within the server. Using SecureIT, there could be the limitation or removal of the vulnerable software that exists between the connectivity of the server and the client. There is also a challenge of the determination of the receipt of genuine data from the clients. This is because the attackers could act as genuine clients and send vulnerable data to the server that in return accepts the data (Williams, 2007). The attackers could use the untrusted data to

The Summer Song Essay Example for Free

The Summer Song Essay When youre are young, it feels like life will carry on forever, and youre very happy. Immortal is used to reveal the boys inflated egos, as they show off to each other and Linda. Price shell have to pay This is adding to the idea of repaying debts, which is mentioned throughout the play, referring to different characters. It could also be a slight mention of Mrs Johnstone, Mickeys mother who gave birth to them both. She is still attached to both of them, even going so far as to give a locket with her picture to Edward, who is now Mrs Lyons son. What fate the later seasons bring, This is adding to the metaphor of the lambs in spring. It is hinting towards the inevitable fate of the slaughter house that lambs face, which the boys soon will. It is mentioned to worry the audience. The lyrics that fit into the foreshadowing category are: Young, free and innocent, This is to emphasise that the boys are still children. Chippy This tells us that Mickey is nearing the end of his life. In the Its just a game scene, Mickey is threatened by frying in chip shop fat, so this is a signal that the boys he will die soon. Last cigarette Cigarettes are associated with death. Last cigarette is a prisoners last luxury before theyre hanged. Its also an allusion to the biblical last supper. Ferry boat This is the idea that the three are being taken to the land of the dead on the River Styx. Broken bottles in the sand, Broken bottles in the sand are hidden, and when you accidentally stand on them they surprise you. This is referring to how unaware the children are of their futures. Oil in the water This brings ideas of pollution, and corruption and spreading fate. Oil and water dont mix, they will always separate. This is like Mickey and Edwards friendship. The use of we in the final paragraph reminds us that we are powerless, and it is the narrator letting us know that hes in the same situation as us, unable to let the characters know of their fate. We do not know whether he is being sarcastic, or would actually like to let them know. Predict no changes in the weather, This reminds us that this happy summer will come to an end. The song is made up of rhyming couplets, which make it sound childish, and adds a sense of finality, so after the last rhyme, you know its over. For young, free and innocent, theres one word for each child. It also makes them seem vulnerable. You know that the innocence will be lost after the song. dreams and fifteen. Have a jarring Para rhyme which interrupts quickly, like what will happen to their lives. The tune of the Summer Song is the first and the last song, Tell me its not true repeated in different themes. Our minds are taken back throughout the previous moments of the play and the first scene when we see Mrs Johnstone with the two dead boys. This connects the audience more to the characters, making it feel harder when the boys die. It suggests that this has happened before, and will happen again. After the first verse there is a pause in the music, to emphasise the narrators last words, The price shell have to pay for just being there. The audience dwells on the idea of the debt that Linda will have to repay, to make up for Mrs Johnstones debt. The line after the pause: But leave them alone, let them go and play, implies that summer is the peak of the year, when everything is at its best, and by the end of it everything is fully developed. It makes you think of leisure, fun, warmth and life. Unfortunately its fleeting, and is soon over, giving way to autumn when everything is wasting away, withering. Some of the lyrics could be portrayed as sarcastic. The song starts in Paradise, and then goes to a chip shop, then darkness, then a filthy beach. The environment seems to get worse and worse. It makes you wonder where they will be next. The first verse is played with a guitar and fairground music and the second is a sleazy saxophone, which clashes with what the narrator is telling us about them being innocent. The last verse is said in a wishful tone, which makes us regretful because we know that these innocent, promising children will soon be dead. At the start of the song, when the children rush on, it gives you an idea of their carefree nature. The narrator interacts with the children throughout the scene. When he is the rifle range man in the first verse, he offers the gun to the children, as if he is slyly hinting at their future. When Linda takes it and misses all three shots, we realise how they have changed, because when they were younger Linda was an excellent shot. The narrator throws them a coconut, and they begin a game of piggy-in-the-middle and Linda gets caught in the middle, at which point they freeze. This is when the narrator talks about the girl in the middle of the pair, the price shell pay just for being there. It emphasises and foreshadows that she will have to choose between the two. The theme of debt shows through here, with the debt transferring to Linda. In the next verse we see them lighting a cigarette, leaning on the lamppost, and suiting their actions to the words. It has a much more grown up feel than the previous verse. In the fourth verse they are at the beach, taking pictures, the first of the two boys, the second of Edward and Linda and the third of Mickey and Linda. Edward and Lindas seem much more genuine and well matched. Then the narrator takes a picture of the three. This makes the audience wish that the children knew of their futures and it makes the picture look empty, and meaningless. When the three exit he says, and only if the three of them could stay like that forever, As if the picture he took could have been more than just a snapshot. It makes you wish time could have stopped. The music of the song is matched to the actions and words. The narrator is always hovering in the background, waiting for a chance to become part of the scene. He is a constant presence throughout so the audience are never relaxed. They are always waiting for him to introduce another twist in the story. Before the Summer Song, he is quite far away, usually in a corner. During it though, he is allowed to come closer to them, and his threats become much more dangerous. The devils got your number hes staring through your window changes to Hes screaming right inside you. The proximity of the narrator to the characters affects the tension of the scene. The overall message of the play is that the inequality of classes is very bad thing, which is enforced as we watch the brothers grow from babies to men, and watch them die. We become attached to them, and regret their death, almost as if its our own fault. The song is when they make the transition from boys to men, and when they become their own people and their true feelings begin to show. Mickey represents the lower class, and Edward the higher. Linda is temptation and the narrator is fate. We see the lower class and the upper class tear each other apart. The second act is darker, as the dream world of child hood, which is reflected in the first half of the summer song, becomes the cold harsh reality of the 80s. I think that the message that Russell wanted to imprint upon the audience is: class is a cruel thing, tearing family and friends apart. The play made me feel sad, and shocked by how Mickey was driven mad enough to shoot his own brother.

Importance of the Nitrogen Cycle

Importance of the Nitrogen Cycle Nitrogen cycle is the central to the biogeochemistry of the Earth, which occupies 79% within the air. Nitrogen is an essential element for plants and animals to grow and to survive. (Soetan, Olaiya Oyewole, 2010). There are 7 atoms number of symbol of N. The life time of reactive nitrogen in atmosphere and in terrestrial are a few weeks and a few decades respectively. (Fowler et al., 2013) This essay would be focusing on the nitrogen cycle, human activity and impact on environment. Nitrogen cannot be bio-used directly, which needs to be transferred by different process such as nitrogen cycle include fixation, assimilation, ammonification, nitrification, denitrification and anaerobic ammonia oxidation. Nitrogen fixation is to turn atmospheric nitrogen into a usable fixed form for plants. (Mior, JWB(editor)2011) Assimilation is the process of how plants absorb nitrogen from soil. (Smil, V. 2000) Ammonification is the process of converting organic nitrogen from expels waste to ammonium. Nitrification is the conversion of ammonium to nitrate. Denitrification is the process of turning nitrates to nitrogen gas, which is the final stage of completing the nitrogen cycle. The biological process of anaerobic ammonia oxidation is to convert nitrite and ammonia to molecular nitrogen. (Nitrogen cycle, 2017). For instance, nitrogen gas would process nitrogen-fixing bacteria in soil or root nodules or lightning, hence to become nitrate compounds. Ammonia can also be converted to nitrates after being converted to ammonia(NH3) (Nitrogen fixation) by the Haber process and converted in the soil or break down and return nitrogen to the air. Proteins would be built up after the plants absorb nitrates from the soil and wait for being eaten by animals, and become animal protein. The nitrogenous wastes in animal urine would become ammonia (process of decomposers or ammonification) and back into soil. Furthermore, the bead bodes of organisms would also being beak down to ammonia and back into soil. (BBC, 2006) In addition, human activities would change the nitrogen cycle base on different factors. Nitrogen would increase with the increases of fossil fuel combustion. Due to the process, would transfer fixed nitrogen from long-term geological reservoirs to the atmosphere. ( Vitousek, P, et al., 1997) Vitousek, P, et al. in 1997 state that human activities increased the quantity of organic carbon stored within terrestrial ecosystems; accelerated losses of biological diversity, especially losses of plants adapted to efficient use of nitrogen, and losses of the animals and microorganisms that depend on them; and caused changes in the composition and functioning of estuarine and nearshore ecosystems, and contributed to long-term declines in coastal marine fisheries Eichner (1990), Schlesinger and Hartley (1992) state that human has impacts on atmosphere and the concentration of volatile NH3 in soils by the agricultural fertilization increases, thus, increase the process of fixed nitrogen and the release more nitrogen gases from soils and groundwater. Nitrogen is a key element that controlling different facets of the earth. Different level of available nitrogen would affect many original plant species and their predators. Therefore, combustion of fossil fuel and many other human activities that increase the level of nitrogen would have environment consequences. Nitrous oxide(N2O) are contributing to climate change. Nitrous oxide is naturally present in small quantities in the atmosphere, however, human activities are increasing the amount in the atmosphere. Nitrogen occupies a important position on climate change mitigation and adaptation. Although nitrogen can cool the effect on climate change, however, the contribution of aerosols makes greater carbon dioxide due to nitrogen fertilization. Furthermore, N2O is a powerful greenhouse gas that causes stratospheric ozone layer depletion. (The nitrogen cascade excess nitrogen in the environment. 2014) In conclusion, ecosystem have own adjustment function to maintain the conditions pre cedent of organism. However, human activities, such as fossil fuel combustion, increase the level of nitrogen, thus, cause the influence of biodiversity and damages of ecosystem. Chain reaction occur after a significant rise of biosphere N2 emissions, for instance: greenhouse gases, accelerated losses of biological diversity and losses of plants adapted to efficient use of nitrogen. Due to human growing population, decreasing the fixation of nitrogen will be a difficult challenge situation in the future. One the other hand, serval ways that can stop the loss of nitrogen from farmland and protect water courses, thus, contributes to plants eutrophication. This type of methods can contribute to the nitrogen-limited waters area. Furthermore, the improvements of the efficiency of burning fossil fuel can also reduce the emissions. The most important factor is to transfer knowledge to developing country. Reference list: BBC. (2006, September 15). GCSE Bitesize: Nitrogen cycle.

How The Ending Of The Novel Manages To End Or Resolve The Novels Key :: essays research papers

â€Å"To Kill A Mockingbird† by Harper Lee is a classic novel that deals with two â€Å"mockingbirds† in Boo Radley and Tom Robinson. â€Å"They don’t do one thing but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird,† says Atticus. Despite the stigma involved with such an action, Maycomb physically and socially kill two Mockingbirds. This theme and many more are resolved in the book’s ending. One of the first key themes dealt with in the ending of novel is that of the first mockingbird, Boo Radley. Throughout the novel Scout, Jem and Dill are preoccupied with one of Maycomb’s â€Å"monsters†, Boo Radley. Finally, Scout has the chance to meet him, after â€Å"He gave†¦. [Scout and Jem] [Their] lives. Scout, through standing on the Radley porch and â€Å"Standing in [Boo’s] shoes and walking around in them†, finally understands Boo Radley. Furthermore, when Scout says, â€Å"he was real nice†, Atticus replies back â€Å"most people are, Scout, when you finally see them†, thus resolving the readers and Scout’s doubts about Boo Radley. With the description of his hair as "feathery," Boo is immediately identified with the "mockingbird" idea, especially with his slight appearance and fluttery hand movements. He has finally become a real person, completing the progression from monster to human; meanwhile, Mr. Ewell's evilness has turned him into a human monster, whose bristling facial stubble felt by Scout suggests an animal-like appearance. Another key theme that is dealt with in depth, is that of the second mockingbird, Tom Robinson, the Negro who is killed trying to escape from jail after he is wrongfully accused and convicted for rape while helping a young woman. At the end of the book, the two mockingbirds collide, as Boo kills Bob Ewell, the young girl’s â€Å"white trash† father, in a scuffle between Bob and the Finch children. As Heck Tate says â€Å" There’s a black boy dead for no reason, and the man responsible for it’s dead. Let the dead bury the dead this time†¦Ã¢â‚¬ . During the course of this book, Harper Lee tries to show us people’s reactions when they have to choose between their prejudices and what is right. Tom Robinson is the recipient of unfair racial prejudice, as he finds out how a man’s false beliefs can override his better judgement. Boo Radley is also the victim of social prejudice. Just because he stays inside, people automatically hide their better judgement in the belief that Boo is actually a monster.

History of Psychology-John Locke and John Mill Essay

Psychology as a recognized science is a fairly new revelation, falling into favoritism only within the past century. Philosophy bears the roots of psychology, and philosophers have been pondering the inner workings of the mind and body for many centuries before psychology came in to favor. One of the key philosophers crucial in the development of psychology in to a formal discipline was Descartes. Their writings influenced more modern Western philosophers such as John Locke and John Mill. From this point, psychology grew into the science it is now recognized as. The Philosophers The 17th century is the cornerstone of philosophy evolving into psychology. Rene Descartes (1596-1650) is often considered to be the inspiration for and credited to be the father of our modern philosophy, and psychology. He is most famously quoted for â€Å"I think, therefore I am† (Descartes, 2006). A human’s ability to reason is the only to find truth. Descartes would also not accept anything to be truth unless there was no discernable reason for doubt. â€Å"The only way to get to the certainty of truth is to arrive at oneself, relying on the clear use of one’s own reasoning powers† (Goodwin, 2008, p.33). Disenchanted with the philosophy he was taught, Descartes found nothing in his learning that could not be left to question. He was said to only believe as truth what could not be doubted and Descartes pursued to find the knowledge he could find within himself (Goodwin, 2008). Descartes was a rationalist and dualist, making him firm believer in the mind and body being two completely separate entities. His beliefs on this are debatable in philosophy and psychology and have been so in the centuries following his life. Philosophers and psychologists to this day are still trying to find the connection between the mind and the body. Western Influences John Locke John Locke was a 17th century British philosopher who is credited with being the founder of Empiricism, the idea that our experiences are our only true source of knowledge. Locke’s view on the formation of ideas was sensation and reflection is the only foundation on which we form ideas. He believed we acquired all of our knowledge form our experiences in the world and in life. Locke compared the human mind to a sheet of white paper. Over the course of life, all of our experiences are recorded upon this paper, our sensations. These sensations can later be recalled, in reflection, to add to new sensations and to acquire new compounded knowledge. John Mill John Mill is considered to be the most important contributor during the British Empirical movement. His contribution stated all knowledge is attained through experience and inborn ideas do not exist. Mill also believed a man should be able to do anything desired as long as the actions do not harm or hurt fellow man in the process. This also affected his views on the necessity of government. â€Å"The only purpose for which power can be rightfully exercised over any member of a civilized community against his will is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant. † (Mill, 2008). Mill found the government to only be necessary for the protection of the people in defense of a war, safety against violence, and to prevent cheating or fraud. Modern Psychology The evolution of philosophy into the science of psychology rapidly took shape in the 19th century. The world was also rapidly changing; the Industrial Revolution created new technologies to help in the advancement of many facets of science. Moving into the next century, advances in the knowledge in anatomy and of the brain further assisted the progress of psychology being a science. Robert Watson was crucial in the study of the history of psychology. Founding a new division of the American Psychological Association, he encourages a study of the history of psychology. As a result, nearly all psychology programs today require a course in psychology’s history. (Goodwin, 2008) Conclusion. Psychology as the science we recognize today is barely more than a century in the making. When following the links to the past and the minds that have gotten us to where we are in psychology today, much it to be learned. From modern medicine and science all the way back to ancient philosophers, psychology is a longstanding and diverse study. References Descartes, Rene (2006).
