Using Named Examples, Assess the Effectiveness of Technologicy free essay sample

Leapfrogging involves the technical aspects of implementing new technologies in the existing technological environments, involving the economic, including financial aspects, the power and broader social interests related to existing and new technology systems, and a wide range of other socio-economic factors. Mobile phones are frequently held up as a good example of technologys ability to decrease the development disparity between MEDC’s and LEDC’s. In the economically lower developing world places with poor infrastructure, few forms of transport and dangerous land lines; mobile phones substitute for travel, allow price data to be distributed more quickly and easily, enabling traders to reach wider markets and generally make it easier to do business. The mobile phone is a prime example of a â€Å"leapfrog† technology: it has enabled developing countries to skip the fixed-line technology of the 20th century and move straight to the mobile technology of the 21st. In Afghanistan, the countrys landline network has been torn to bits by 20 years of war.

To put new wires in the ground would take decades and be prohibitively expensive. Instead, installing a modern mobile phone network is cheaper, quicker and easier. From having limited phones, the wealthy Afghan people are using one of the latest western communications devices. When the mobiles first went on sale in Afghanistan earlier in the year, nearly 400 people have spent $350 for a handset in order to stimulate their businesses or simply to increase their social life. Although the mobile phone technology is cheaper, it is still quite costly and only the rich citizens of the nation’s poverty stricken population can afford the technology. Therefore it is only benefiting the wealthy, who probably could have afforded to repair the landline technology. The term GM food are most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. Genetically modified plants have been widely publicised as the future in agriculture. Many believe that it may help improve crop harvests and farm productivity by developing genetically modified crops that can either resist pests or chemicals. But despite the promise that GM crops may offer, there are still doubts that linger among a number of people as well. There are concerns that the introduction of GM crops in developing countries might lead to a reduction in biodiversity, particularly in areas where a crop originated and a wide range of natural genetic variation is found. There might also be unexpected consequences of gene transfer (between plants, for example an uncontrollable ‘escape’ of genes into neighbouring wild plants by pollen. There are also concerns that pests or weeds could acquire resistance to crops. Therefore their effectiveness is questioned and would probably hinder the development process, as developing countries would have to deal with further environmental issues. Furthermore, five agricultural biotechnology corporations now control most of the technology needed to develop GM crops. There are concerns that these companies and those who own property rights have undue influence over the availability of GM crops and the research involved currently only serves the interests of large-scale farmers in developed countries meaning it has very little productivity for the development process – thus increasing the development gap further. However, there are benefits of GM crops that support the development process. Sub Saharan Africa, well known for its arid climate and also known for its development decline can benefit from GM crops as a technological leapfrog. A gene from a plant which can survive prolonged water stress in desert conditions has been introduced into rice, this allows rice to produce a sugar that protects the plant during dehydration, allowing it to survive periods of drought. In addition, crops can be genetically modified to contain additional nutrients that are lacking from the diets of many people in developing countries. One example is Golden Rice, which has been modified to have enhanced levels of Beta-carotene, in order to help to prevent vitamin A deficiency which 14 million children under five suffer clinically from, which can cause childhood blindness. Thus, the GM crop will assist Sub Saharan African countries with the Millennium Development Goal of eradicating poverty and hunger and general deficiency issues, which will therefore contribute to the development process. In conclusion, technological leapfrogging has assisted many developing countries to decrease development disparity with the Global North. Both the mobile phone and GM crop technologies are modern and advanced, allowing developing countries to gain economic, social and environmental benefits. Although there are some issues because it is 21st Century technology there will always be upgraded technology, which means the leapfrogging will only decrease the development gap, not actually balance the core and periphery. z

Sonnet 116 Analysis

Sonnet 116 Analysis Sonnet 116 is one of the most famous poems in Shakespeare’s â€Å"Sonnet† collection. The popularity of this poem can only be matched by that of other poems such as sonnet 18 and 130. Sonnet 116 is often referred to by its first line, â€Å"Let me not to the Marriage of True Minds†.Advertising We will write a custom research paper sample on Sonnet 116 Analysis specifically for you for only $16.05 $11/page Learn More The type of love that is defined in this poem has been replicated in various poetic works. In this poem, Shakespeare paints the picture of what constitutes an ideal love. The poem talks about a love that never changes, never admits inferiorities, never fades, and goes beyond death. This poem represents Shakespeare’s innermost beliefs about love. Shakespeare’s description of love in this sonnet is often quoted by other numerous works of literature. The love defined in this poem has often been thought to be an acc urate representation of true love. According to the speaker in this poem, love that is immortal, permanent, and never changing qualifies to be termed as true love. The last line of the poem captures this sentiment using the words that â€Å"†¦no man has ever loved† (Shakespeare 14). Shakespeare subdivides his poem in a manner that covers his core beliefs about love. This subdivision makes it simple for the poet’s message to be understood. The first part of this poem addresses the unchangeable aspect of love. The second part of the poem addresses the permanent nature of love by likening it to a â€Å"guiding star unshaken by tempests† (Shakespeare 6). The third subdivision of this poem argues that the nature of love is not subject to the passage of time. This means that love is not supposed to change as time passes. The subdivision of the poem into opinions about love helps simplify this poem. This arrangement is also used to build momentum for Shakespeareâ €™s message (Vendler 56). Shakespeare uses a strong first line to convey his innermost feelings about love. The first line in this poem is Shakespeare’s declaration about his intentions not to interfere with the union between two lovers. In the first line, the speaker declares that â€Å"Let me not to the marriage of true minds† (Shakespeare 1). It is the poet’s belief that nothing should come between two people who are in love. The powerful message in the poem’s first line is matched by a strong closing line. In the last line of the sonnet, the speaker reckons that if love ends, it never existed in the first place. The message found between the opening and closing lines is able to maintain the poem’s original momentum.Advertising Looking for research paper on british literature? Let's see if we can help you!

According to the speaker, love’s biggest deterrent is the passage of time. To emphasize the importance of this recognition, the poet capitalizes one line in the poem. The ninth and the tenth lines in the poem say that â€Å"Love’s not Time’s fool, though rosy lips and cheeks/ Within his bending sickle’s compass come† (Shakespeare 9). The ninth line in the poem capitalizes the word ‘time’ to indicate that Shakespeare considers time an important aspect in the dynamics of love. According to Shakespeare, time is love’s greatest enemy. In the tenth line, the poet used the word sickle to underline the destructive nature of time. Just like death carries a sickle waiting to pounce on life, time scouts around waiting to pounce on love. Shakespeare argues that true love cannot be overcome by the element of time. In addition, true love cannot be ‘fooled by time’ or be me asured by the passage of time. Shakespeare’s understanding of true love is that it is eternal and it is not affected by passage of time. The language and the style used in this poem only enhances Shakespeare’s message of love. The poet uses imagery and metaphors sparingly and stays true to his love message. Even when imagery is used in the poem, it only serves the purpose of enhancing the message of love. The most prominent imagery in this poem is the sickle of time. On the other hand, the most prominent metaphor in this poem is that of â€Å"love as a guiding star† (Nelson and Cling 16). This metaphor overstates the poet’s views about the importance of love. Considering this is a standard poem, this is very reserved use of stylistic devices. By abstaining from heavy use of stylistic devices, Shakespeare is able to convey the deep nature of the love he is talking about in the poem. Even the poem’s structure is used to underline the message of love and its deep nature. The poem flows from start to finish and makes use of rhyme patterns in the process. The primary rhyme in this poem is quite strong while the secondary rhyme pattern bears the weaker rhymes. The last line in the poem indicates how much faith Shakespeare has with this message. In the last line Shakespeare, declares that if his claims were wrong, he would refrain from writing. Moreover, Shakespeare declares that if this message is wrong all his other messages are also wrong.Advertising We will write a custom research paper sample on Sonnet 116 Analysis specifically for you for only $16.05 $11/page Learn More Nelson, Jeffrey and Andrew Cling.

How to Make a Colored Campfire

How to Make a Colored Campfire A campfire always adds warmth and excitement to an outdoor experience, but you can easily kick it up a notch by coloring the flames. There are several ways to achieve the effect, so you can choose one that works best for you. Sprinkle Chemicals on the Campfire You can buy little packets of chemicals to sprinkle over a campfire to make colored flames, but its easy to make these yourself. Simply add chemicals to a zipper plastic bag and add them to the fire. Its best to add chemicals after youre done cooking, to avoid any chance of accidental contamination. These chemicals arent very toxic, so they wont produce dangerous smoke or harm the ground. white - magnesium sulfate (Epsom salt)yellow - sodium chloride (table salt)green - borax (laundry booster or roach powder), boric acid powder (disinfectant), or copper sulfate (algae treatment)blue - copper chloridepurple - potassium chloride (salt substitute)pink - lithium (from a battery) or lithium chloridered - strontium nitrate or strontium chloride (in emergency road flares)orange - iron oxide (rust) Most of these chemicals you can get at a grocery store. Others you can order online. There are also many more chemicals that produce colored fire, based on the flame test, but be sure to check how safe one of these other chemicals is before adding it to a campfire. A word of advice: if you can, avoid adding yellow (sodium chloride) because it will overpower all the other colors! Anyway, a campfire is mostly orange and yellow, so you dont really need those colors. My personal preference is just to use copper sulfate. Why? The salt manages to produce almost the entire spectrum of colors all on its own, plus copper is already present in relatively high concentration in soils. Its also pretty easy to find. Burn Driftwood If your campfire is located near the beach, you can get a colored fire simply by burning driftwood. Driftwood produces an eerie blue to purple flame. The natural salts that have soaked into the wood to produce the color also produce a smoke that isnt good to breathe, plus you should not cook over a driftwood campfire, but on a still night, the effect is breathtaking. Add Chemicals to Paper, Sawdust, or Pinecones Another way to make a colored campfire is to add pre-treated paper, sawdust, or pinecones to the fire. Make a mixture of the desired material with one of the coloring chemicals and a small amount of water or rubbing alcohol. Some chemicals dissolve better in rubbing alcohol, producing better results. Let the chemical solution soak in ​for several hours or overnight. Allow your material to dry. You may want to spread it out a bit to speed up the process. You can pack it in a paper or plastic bag, and carry it with you on your camping trip. Toss a treated pinecone, handful of sawdust, or crumpled sheet of treated paper into the campfire to color the flames.

Invention of Press and Advertisement Technology Essay

Invention of Press and Advertisement Technology - Essay Example The parts of the Columbian printing press included the American eagle perching rebelliously with not only outstretched wings but also open beak on the focal counterbalance lever. The eagle acted as a counterbalance weight that was adjusted by sliding it along the focal counterbalance lever (Mullins 17). The clutching of a flight of Jove’s thunderbolts by the eagle’s talons represents war while on the contrary the olive branch of peace, as well as Horn of Plenty, signifies prosperity. The main counterbalance is tipped in one of its ends to form an arrow that rests in the horn-like opening of the crescent moon. The other end of the counterbalance is coiled to form something like a dolphin; its open jaws suitably hold the hook that connects it with the top end of the great lever (Mullins 17). A similar creature (dolphin) also extends along the top front of the great lever. The Columbian has two pillars that are decorated with the caduceus. The right-hand pillar also has a conventional ear of wheat near its top. The type table of the Columbian was also made out of iron, and it was wound below the printing platen (Mullins 17). Printing of the materials was enhanced by exerting force through a wood on the printing table. The Columbian printing press stands on four legs made of iron. The ends of the legs are molded to form something like the paws of a lion. Despite proving to be a bit faster than the past printers, advancement in technology led to other inventions that led to the abandonment of the use of weights and levers. For instance, mechanization of printing was started in 1824. As a result of this, gears and power were added to the wooden-framed platen press. This type of press led to the production of high-quality prints in the nineteenth century. The new media today incorporates computers into the printing process. The balancing of the elements for quality production of prints is not done physically by balancing weights. The development of electronic devices in addition to other technological devices has led to the evolution of printing.

Epidemiology - Essay Example In contrast, absolute measures, computed as a difference rather than a ratio, produce estimates with quite different interpretations. a) The type of misclassification portrayed in this case study is non- differential and random. The same misclassification occurs in the same proportion in each group. The percentage unto which the cases were underestimated is the same percentage, which the controls were over estimated. These leads to an underestimation of the true association hence the true association cannot be established. A relative risk ratio of more than one indicates that the occurrence of the event at hand is more likely to the experimental group than the control group. This misclassification reduced the relative risk ratio hence reducing the likelihood of the event occurring to the experimental group. This means underestimating the true association. b. Outcome variables of a study are measurements of population’s current status which might include mean, mode and median of continuous counts of measurements for example radio frequency exposure in megahertz, age, duration of exposure of radiation in hours and type of phone used. c. Study factors (exposures): cellular phone calls radio frequency measure by the kind of phone used, the duration of use and the ear use to receive the call. The second factor is brain tumor measured by anatomical area of the tumor. 2. a. The participation rate in this study is the percentage of the total number targeted that participated in the study =2899/3234*100=89.64%. The high participation rate is one of the characteristic of a good epidemiologic study. This implies that the results of the study are highly representative of the actual population. b. Response rate in survey research refers to the ratio of number of people who answered the survey divided by the number of people in the sample. It is usually expressed in the form of a

Hippies :: Hippie 60s Flower Power

Hippies When people hear the word hippie, they usually think of flower power, peace, love, and drugs. The 60's may have been a far out decade, but what most people don't know is the impact these idealists had on our world during that time. This generation of people can make almost anyone interested because of the things they believed in, why they expanded their minds and their contributions to today's world. Hippies were very down to earth people, they believed in peace and love, and hated the Vietnam War with a passion. With these beliefs came Flower Power. Flower Power was a peace movement designed to help stop the Vietnam War. Hippies, mostly young women, would hand out flowers at random to people walking down the streets of New York. They said it showed the love and respect they had for the world, and other people. The purpose of flower power was to show everyone that peace and unity is more important than aggression and dominance. During the spring of 1967, there was a ?love-in? at New York?s Central park. This was a gathering of over 10,000 people wearing exotic costumes, and body paint. They all gathered for a day of music, dancing, drugs, and celebration in hopes to get their word across the world about the war. One person who played at this even was Jimi Hendrix. Soon after there was an even bigger gathering held by these people, it was on a farm around 50 miles away from Wood stock. This was a 3 day gathering where they shared food, blankets, and drugs. Although there was skinny dipping, pot, and acid, there was not a single act of violence, thievery, or fighting. According to Galenet, the stage was built by 300 hippies in exchange for 2 meals a day, for the 3 day period, and all the pot they could smoke. They also hired the Hells Angles as security for this event, which was one of the muddiest and biggest sit-ins ever. With all these large gatherings, their main goal was to get their word out to the world about peace and love among everyone in hopes that the world will follow.

Lady Macbeth’s Diary Essay

At the beginning of today I was received a letter from my dear husband, Macbeth he told me of how he was triumphant in both battles, with his day of success being ended with predictions of his future by â€Å"Three Weird Sisters†. Who the hailed him with Thane of Glamis, Thane of Cawdor, and king hereafter. It is said they have more than mortal knowledge and if this prediction came true I shalt be Queen! Macbeth tells me later he found out from a messenger from the King he was to be the new Thane of Cawdor, the prediction had come true in a matter of minutes. The other prediction must come true too and I shalt make it. A messenger then came and told me that the king was coming to our castle tonight! This was our chance to kill King Duncan! I wished to me made unsexed and I called upon the spirits to help me become evil and full of direst cruelty. I also asked for my women’s breasts to be filled with gall. I must with Macbeth do the deed but I want no remorse I must be evil from hereafter! I told Macbeth what we are to do and I know he is weak so he must be strong like me and become an innocent flower but be a serpent under it. He isn’t sure about killing Duncan but he must go through with it. He deserves to be King and I need to be Queen! I told him I would make the plan as I know he is too full of human kindness but I would still have to use threatening and harsh persuasion to convince him. Everything was ready yet Macbeth the fool that he was left Duncan’s chamber to tell me in a weak voice that ‘we shall proceed no further in this business’ I had to tell him what a coward he was and how he would do it if he loved me. But he fell for it yet again the sweetie! He will soon become evil like me and we can become a partnership as we were meant. To persuade him to do this murder I told him how un- man he was and he backed away not yet convinced. But I told Macbeth how he knows how much I love the baby that milks me but if I had promised so to him as he has done to me. How I would as it was smiling in my face have plucked my nipple from its boneless gums and killed it. (I used the word dashed its brains out to make it more terrifying for him) Yet I convinced him and he rose upwards and forward with me in a partnership of evil to kill Duncan. He even thought about planting the daggers on the drunken guards so it would be more obvious it was them! He has gone now to try and do it. I just hope he does actually go through with this deed and doesn’t manage to get caught or give it away! Even if he gets caught I shall be Queen it just means I don’t need a coward like him!
