The Danger of a Single Story According to Adichie Essay 1. According to Adichie, how is Africa often described? According to her, Africa is often described as a place of beautiful landscapes and animals with incomprehensible people fighting senseless wars, dying of poverty and aids. It is a continent of catastrophes where people are pitiful illiterate aborigines who have no possibility of being human equals. They are unable to speak for themselves and are waiting for foreigners to save them. All in all, Africa is a lowly continent with nothing more but scenic places with starving people. 2. Did it affect Africa? How? Yes, it affected Africa so much because it only showed all the negative sides of Africa and did not illustrate the beauty of the continent. It shows that Africa is a poor continent with even poorer people who does nothing to improve their lives. It does not indicate all the magnificence of the continent and the attributes of the people in it. Africa is degraded because of these inadequate and unfitting descriptions. 3. What is a single story? What is the power of single story? A single story is a view of something, somewhere or of someone that only shows one side of the coin. It is incomplete. It may have different versions but they all have the same view. For example, what if I tell you that Boracay is a dirty place where people have no regard for nature? The beach is filled with moss and there are plastics everywhere? What if all the things you have heard about Boracay is something like this? It doesnÃ¢â¬â¢t sound inviting, does it? But what if I tell you that those who disregard nature are punished and that they clean up all the rubbish they find. That Boracay is a paradise? Now that is a pleasing sight isnÃ¢â¬â¢t it? That is an example of what a single story is. It shows only one point of view. And from that point of view builds another story and so on that will not convey the whole truth about the topic. A single story can be very powerful indeed because it blinds people from a great deal of things. It shows things, places or people as one thing only and emphasizes on the differences and not the similarities. It can not only make a story but it can also make it the only story of that particular topic.

Thesis Statement: Bob MarleyÃ¢â¬â¢s life affected his writing and contributed to the development of his poetry. Bob Marley is without a doubt the greatest musician a third world country ever produced. Through Rastafari ideas, he influenced many others with songs that touched the lives of millions with his constant message of unity. His wisdom through experience helped him achieve a grand distinction over other artists. In the year 1944, Captain Norvol Marley, a middle-aged white marine officer, married a young Jamaican girl named Cedilla Booker. On February 6, 1945 at two thirty in the morning their son, Robert Nesta Marley, otherwise known as Bob Marley was born in his grandfatherÃ¢â¬â¢s house (The Story). Soon after Bob was born his father left his mother. BobÃ¢â¬â¢s Father did, however give financial support and occasionally arranged to see his son. It was now the late fifties and jobs were scarce in Jamaica. Bob followed his mother from their home in St. Ann to Trenchtown (West Kingston) to seek employment in the big city. Ã Ã Ã Ã Ã Trenchtown got its name because it was built over a ditch, which drained the sewage of old, Kingston. In Trenchtown Bob spent a lot of his time with his good friend Neville Livingston, who people called by his nickname, Bunny. He began to attend a music class with Bunny, which was held by the famous Jamaican singer Joe Higgs. In that class they met Peter Macintosh and soon became good friends. When Bob was 16, he started to follow his dream of becoming a musician. According to Michael Anderson, Ã¢â¬Å"Music to many young Jamaicans was an escape from the harshness of everyday lifeÃ¢â¬ (Anderson, 1). BobÃ¢â¬â¢s life looked brighter on February 10, 1966 when he married girlfriend Rita Anderson. Rita gave birth to their first born whom they named Cedilla. Stephen, Sharon, and Ziggy then followed Cedilla. Ã Ã Ã Ã Ã Bob Marley had quite a massive rÃ ©sumÃ © for his artistic career. It first started when he met Jimmy Cliff, who at the age of 14 had already recorded a couple of hit songs. After meeting Bob, Jimmy introduced him to Leslie Kong, a local record producer. Bob followed his advice and auditioned for Leslie Kong (Lieblich, 7). BobÃ¢â¬â¢s musical talents shone much more brightly than anyone else that day and found him in the studio recording his first single Ã¢â¬Å"Judge NotÃ¢â¬ . Unfortunately neither Ã¢â¬Å"Judge NotÃ¢â¬ nor his 1962 single Ã¢â¬Å"One More Cup of CoffeeÃ¢â¬ did very wel... .... He used his ideas and beliefs not to create but to solve problems. The life he lived as a Rasta allowed him to generate songs that are treasured significantly. It has always been said legends never die and with such musical genius, Bob MarleyÃ¢â¬â¢s legend will live on. BIBLIOGRAPHY Hauler, Joe. Ã¢â¬Å"Bob Marley Biography.Ã¢â¬ MSN Search. Online.

Grignard Reagents were discovered by Victor Grignard in 1900. They are classically formed by reacting magnesium turnings with alkyl halide in ether or THF solvents, to form solutions of alkylmagnesium halide. The atmosphere must be moisture Ã¢â¬âfree and inert and magnesium must be of high purity.Ã Magnesium is usually covered with a coating of magnesium oxide, so an activation agent like Iodine or Dibromoethane is added. They can also be formed from by when an organolithium compound reacts with a magnesium halide In organic chemistry C-C bond is one of the most important bonds. To make these C-C bonds organometallics such as organolithiums, Grignard reagents and carbonyl compounds are used. Grignard reagents are our first source of carbanions (anions of carbon). The polarity of a covalent bond between two different elements is determined by electronegativity. The more electronegative an element is, the more it attracts the electron density in the bond. Hence, the greater the difference in electronegativity, the more polarized a bond becomes. In the extreme case of complete polarization, the covalent bond ceases to exit and is replaced by electrostatic attractions between ions of opposite charge. The reactivity of the carbonyl groups is due to the polarization of the carbon-oxygen bond toward the more electronegative oxygen. For e.g. Ã¢â¬â Polarity inside a Formaldehyde molecule Thus organometallic reagents act as nucleophiles towards the electrophilic carbonyl group. In organolithium compounds and Grignard reagents, the key bond is polarized in the opposite direction, towards the carbon Ã¢â¬â making carbon a nucleophilic centre. This is true for most organometallics because, metals like Li, Na, K, Mg, ca, Al, Cu, Zn etc. all have lower electronegativity than carbon. Also, the alkali metals (Li, Na, K etc.) and the alkaline earth metals (Mg and Ca, together with Zn) are good reducing agents, the former being stronger than the latter. Ã Hence, these can be used to make organometallic reagents with carbon. The alkyl magnesium halides are called Grignard Reagents after the French chemist, Victor Grignard, who discovered them. The other metals mentioned above react in a similar manner, but the Li & Mg are the most widely used. Feature Article Relative Rates:Ã Free-Radical Bromination These reactions are substitution reactions, but they cannot be classified as nucleophilic substitutions, as in the reactions above. Because the functional carbon atom has been reduced, the polarity of the resulting functional group is inverted (the original electrophilic carbon becomes nucleophilic). This change, shown below, makes alkyl lithium and Grignard reagents unique and useful reactants in synthesis. Reactions of organolithium and Grignard reagents reflect the nucleophilic character of the functional carbon in these compounds. The nucleophilic carbon of these reagents also bonds readily with electrophiles such as iodine and carbon dioxide (fifth equation). The polarity of the carbon-oxygen double bonds of CO2 makes the carbon atom electrophilic, shown by the formula in the shaded box, so the nucleophilic carbon of the Grignard reagent bonds to this site. Carbon has in consequence an unshared electron pair. Such a carbon would be a very strong base, much stronger than needed to take an H+ from water to generate the weaker base OH-. A practical consequence of this is that Grignard reagents must be kept dry, away from even the slightest traces of moisture, lest they be destroyed by reaction with water.

Summertime means watermelon, ice cream cones, and barefoot nights on the beach. Summertime also means juicy watermelon stains on clothes, chocolate splotches on the overalls, and stinky feet dipped in mud pies. When it comes to summertime there is no denying the beautiful sunshine and relaxing nights in the yard, but it also means more messy children. Fortunately, with so many wonderful companies such as Right Bank Babies and Crocs, mothers and fathers have less worrying to do about having children that look muddled and disheveled at those family barbeques or summer festivals. If you purchase these brands, your children will look fashionable and clean at any upcoming summer event. Right Bank Babies is a very unique clothing company forÃ¢â¬ ¦show more contentÃ¢â¬ ¦The dresses may also turn into flared shirts once your child has outgrown it. Crocs may not be the cutest sandal around, but do they come in handy! Children are often seen playing on playgrounds in the summer heat wearin g flip flops and open toed sandals. While these types of sandals could be unsafe because children s feet can easily come out of the shoe while climbing, parents should consider investing in a pair of Crocs for their children. These sandals are basically a rubber type clog that has a backing strap. Not only is the rubber excellent for cleaning, it is also airy because of the ventilation holes that let out feet sweat. If a chocolate ice cream cone drips on the Crocs, it is easily washable and extremely easy to dry with a bit of soap and water. Needless to say, they are excellent to wear in the water as well. Sneakers and sandals made of cloth or leather are considerably harder to keep clean, especially in the carefree summer months. The Crocs are made of a specially designed material called Patented Closed Cell Resin that actually resists feet fungus. Celebrity parent Liv Tyler and her child Milo have been seen sporting the Crocs around town. Crocs come in various styles such as Crocs Athens Kid s, Crocs Caymen Kid s, Crocs Crocling, Crocs Disney Kid s, and Crocs MaryJane. A pair of Kid s Crocs will cost you right around $25.00.
