The passage brings racism to light as the mother warns that a similar fate could happen to sonny. Lastly it shows the oppression that the sonny and his brother but also their family had to face and try to overcome in that era. One of the main points of Sonny’s blues is the narrator and Sonny trying to strive to be better and rise above. The narrator did in fact rise by becoming a teacher and sonny try to rise above by becoming a jazz musician. The darkness that was mentioned could be viewed as sense of general hopelessness that pervaded African Americans back when Baldwin was writing these short stories. The darkness in this story could be referred to the effects of racism; the suffering that is spoken about in the story perhaps could have been inherited from generation to the next in the African American community. Baldwin constantly mentions the Harlem Renaissance in all of his writings, the Harlem renaissance was very important to African American literature because it was it brought new attention to it.

The Morality of Lying in Contrast to the Philosophies of...

The young girl gazes at you helplessly from within the tangled wreckage. You witnessed the crash – a massive truck careened into a minivan as it passed on the highway, killing the driver on impact, and virtually tearing the girl in half. Now she hangs from the car, held together by the seatbelt. Her nervous system critically damaged, she can’t feel much pain, but she knows that her situation is not optimal, to say the least. She is six years old – she probably doesn’t understand the concept of death. As you stare equally helplessly into her fear stricken eyes, the only words that you can muster are: â€Å"Don’t worry, everything will be okay.† This is obviously a lie – there is absolutely no chance that the dying girl will indeed survive and†¦show more content†¦For this paper, it is necessary to distinguish several of those forms, which vary in severity. First, there is the simple white lie, which is defined as â€Å"a trivial lie that is told for diplomatic or well-intentioned reasons.† These are typically inconsequential responses made in an effort to preserve one’s feelings, such as in the clichà © case of a spouse asking, â€Å"Do these jeans make me look fat?† They rarely have any lasting effect, and are, for this argument, considered moot. On the other side of the scale is the outright lie, also known as deception, which is â€Å"a sender intentionally trying to get someone to believe something that the sender knows to be false† (Gass Seiter, 1999). These lies are the sort that have most often garnered scorn, as they are typically malevolent (or at the very least, selfis h), and utilized to serve a personal end. We will see that this is not always the case, but for the sake of argument, the â€Å"outright lie† will begin as an evil. Lying, as a whole, is perceived negatively, because it is most commonly used in negative instances because the sender wants to protect themselves from pain and embarrassment. It is the attempt to avoid punishment or retribution that spurns most people to lie, and therefore, the concept of speaking such an untruth became associated with the consequences of something injurious, and is frowned upon.

Social Protection in Developing Countries - 990 Words

The global crisis has sharply underscored the need to strengthen social protection institutions in developing countries, and especially in low income countries. Before the onset of the crisis in November 2008, a growing body of research had accumulated proving a comprehensive knowledge base demonstrating that social protection programmes are effective instruments in reducing poverty and enhancing human development. In the decade prior to the onset of the crisis a large number among the new social protection programmes had emerged in the South with a specific focus on children. Children are the largest group within the global poor, and by investing in children’s development, social transfers contribute to providing a permanent exit from†¦show more content†¦The issue how to finance an extension of social protection in developing countries calls for hard headed, innovative responses. The paper is organised as follows: Section two examines three approaches to financing social protection for children, including the resource mobilisation approach, which highlights the potential role of national government revenue collection efforts, and that of international aid in low income countries. It also considers the insurance approach which puts the emphasis on the socialisation of the costs of poverty and vulnerability. Finally it discusses redistribution at the national level as a potential means to finance the extension of social protection for children. The paper finds that it is helpful to cast issues of financing in a broader context than the techniques and mechanics of revenue collection of the machinery of redistribution, important though these are. An optimal financing mix should do three jobs well: (i) generate the resources needed to establish and strengthen appropriate social protection systems; (ii) ensure that the incentives generated by the financing modalities reduce child poverty and child vulnerability; and (iii) secure legitimacy for social protection institutions and policies.

Left-handedness free essay sample

Harsh Patel â€Å"The 51-per-cent minority† by Doris Anderson Compares treatment of women to Quebecers, residence of Atlantic Provinces, left handed people, Doctors, Blacks and Indians. Canada as a country can’t tolerate discrimination with different religion and race, but it can tolerate â€Å"all of these discriminatory practices which are being inflicted on women today in Canada†. Anderson’s essay â€Å"The 51-per-cent minority† is a deductive essay. The general principle is explained through the title â€Å"The 51-per-cent minority† which is saying even though women account for 51% of Canada’s population they still get discriminated upon. A test case that supports the general principle is when women workers earn, on average only 70 cents for every $1 man gets- even though on average, women are better educated than men. Therefore, all the discriminatory practices would be set aside if women were anything else but a woman. The essay â€Å"The 51-per-cent minority† by Doris Anderson is a deductive comparison between the treatment of different races, religion and women. We will write a custom essay sample on Left-handedness or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Anderson seems to be well aware of what’s going on around her in terms of minorities and different sexes. The process of the essay is very clear in terms of argumentation. She seems to capture reader’s attention during the introduction when she uses irony. This could be considered hidden assumption because the reader is supposed to realize a bigger meaning than what’s actually in the essay. But the writing process does consist of some flaws, because Anderson doesn’t start with the main idea of the essay the readers might have to go back and re-read the essay to get their thoughts straight. I think that this essay is not overgeneralized due to the presence of strong evidence to support her claim. This evidence not only addresses her key claims but all the oppositions. She has much statistical evidence which are researched facts. But in Anderson’s essay their seems to be Oversimplification, this is because even though treatment of every human being is important, including women, there are much more complex and important concerns to deal with. Even though Anderson talks about the deprived rights of Canadian women, she doesn’t compare them to women globally like, women in China, Afghanistan, Iraq and etc. Some of these women are not allowed to show their face in public or go out of the house alone. The evidence is so out of date that is works as a negative factor against the essay. This essay was written in 1980 which is more than 31 years ago and since then the world developed into a new age where men and women are treated equally in most part of the world. The credibility of the evidence cannot be questioned because Doris Anderson was once the president of the Canadian Advisory council on the status of women. Even though this essay has some flaws to it, the essay is very clear. In Doris Anderson’s â€Å"The 51-per-cent minority † the main focus ends up being on the treatment of women. But what Anderson doesn’t take into consideration is what happens to the countries which haven’t started accepting the idea of equality for women. India was known to be a developing country couple of years ago and back then women only had one job; housewives. It has been documented that 70 to 80 years ago when women were born they were killed because the parents would have to give dowry when they got married. India is not the only country that functions like this but also; Pakistan, Afghanistan, Iraq, Sri Lanka and many more. Such countries just need some pointers and a starting point from which they can change the way they treat and think about the women of their country. So Doris Anderson should have taken countries of other women into consideration when she wrote this article.

Detection Of Biological Molecules Essay Example For Students

Detection Of Biological Molecules Essay Detection of Biological MoleculesIntroduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus,life wouldnt exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds,and disulfide bonds. Covalent bonds are especially strong, thus, are present inmonomers, the building blocks of life. These monomers combine to make polymers,which is a long chain of monomers strung together. Biological molecules can bedistinguished by their functional groups. For example, an amino group ispresent in amino acids, and a carboxyl group can always be found in fatty acids. The groups can be separated into two more categories, the polar, hydrophilic,and the nonpolar, hydrophobic. A fatty acid is nonpolar, hence it doesnt mixwith water. Molecules of a certain class have similar chemical propertiesbecause they have the same functional groups. A chemical test that is sensitiveto these groups can be used to identify molecules that are in that class. Thislab is broken down into four different sections, the Benedicts test forreducing sugars, the iodine test for the presence of starch, the Sudan III testfor fatty acids, and the Biuret test for amino groups present in proteins. Thelast part of this lab takes an unknown substance and by the four tests,determine what the substance is. BENEDICTS TESTIntroduction: Monosaccharides and disaccharides can be detected because oftheir free aldehyde groups, thus, testing positive for the Benedicts test. Such sugars act as a reducing agent, and is called a reducing sugar. By mixingthe sugar solution with the Benedicts solution and adding heat, an oxidation-reduction reaction will occur. The sugar will oxidize, gaining an oxygen, andthe Benedicts reagent will reduce, loosing an oxygen. If the resulting solutionis red orange, it tests positive, a change to green indicates a smaller amountof reducing sugar, and if it remains blue, it tests negative. Materials: onion juice5 test tubes1 beaker potato juicerulerhot plate deionized waterpermanentmarker5 tongs glucose solutionlabels starch solution6 barrelpipettes Benedicts reagent5 toothpicksProcedure: 1.Marked 5 test tubes at 1 cm and 3 cm from the bottom. Label testtubes #1-#5. 2.Used 5 different barrel pipettes, added onion juice upto the 1 cm mark of the firsttest tube, potato juice to the 1 cm mark of the second, deionized waterup to the 1cm mark of the third, glucose solution to the 1 cm mark of the fourth,and thestarch solution to the 1 cm mark of the fifth test tube. 3.Used thelast barrel pipette, added Benedicts Reagent to the 3 cm mark of all 5test tubes and mix with a toothpick. 4.Heated all 5 tubes for 3minutes in a boiling water bath, using a beaker, water, anda hot plate. 5.Removed the tubes using tongs. Recorded colorson the following table. 6.Cleaned out the 5 test tubes with deionizedwater. Data:Benedicts Test ResultsDiscussion: From the results, the Benedicts test was successful. Onion juicecontains glucose, and of course, glucose would test positive. Starch doesnthave a free aldehyde group, and neither does potato juice, which contains starch. Water doesnt have glucose monomers in it, and was tested to make sure the endresult would be negative, a blue color. IODINE TESTIntroduction:The iodine test is used to distinguish starch frommonosaccharides, disaccharides, and other polysaccharides. Because of itsunique coiled geometric configuration, it reacts with iodine to produce a blue-black color and tests positive. A yellowish brown color indicates that the testis negative. Materials: 6 barrel pipettespotato juicestarch solution 5 testtubeswateriodine solution onion juiceglucose solution5 toothpicksProcedure: 1.Used 5 barrel pipettes, filled test tube #1 with onion juice,second with potatojuice, third with water, fourth with glucose solution, and fifth withstarch solution. 2.Added 3 drops of iodine solution with a barrel pipette,to each test tube. Mixedwith 5 different toothpicks. 3.Observed reactions and recordedin the table below. Cleaned out the 5 test tubes. Data:Iodine Test ResultsDiscussion:The iodine test was successful. Potato juice and starch werethe only two substances containing starch. Again, glucose and onion juicecontains glucose, while water doesnt contain starch or glucose and was justtested to make sure the test was done properly. .udd0ba26df6cd4ac11805ac222eda256c , .udd0ba26df6cd4ac11805ac222eda256c .postImageUrl , .udd0ba26df6cd4ac11805ac222eda256c .centered-text-area { min-height: 80px; position: relative; } .udd0ba26df6cd4ac11805ac222eda256c , .udd0ba26df6cd4ac11805ac222eda256c:hover , .udd0ba26df6cd4ac11805ac222eda256c:visited , .udd0ba26df6cd4ac11805ac222eda256c:active { border:0!important; } .udd0ba26df6cd4ac11805ac222eda256c .clearfix:after { content: ""; display: table; clear: both; } .udd0ba26df6cd4ac11805ac222eda256c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .udd0ba26df6cd4ac11805ac222eda256c:active , .udd0ba26df6cd4ac11805ac222eda256c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .udd0ba26df6cd4ac11805ac222eda256c .centered-text-area { width: 100%; position: relative ; } .udd0ba26df6cd4ac11805ac222eda256c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .udd0ba26df6cd4ac11805ac222eda256c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .udd0ba26df6cd4ac11805ac222eda256c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .udd0ba26df6cd4ac11805ac222eda256c:hover .ctaButton { background-color: #34495E!important; } .udd0ba26df6cd4ac11805ac222eda256c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .udd0ba26df6cd4ac11805ac222eda256c .udd0ba26df6cd4ac11805ac222eda256c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .udd0ba26df6cd4ac11805ac222eda256c:after { content: ""; display: block; clear: both; } READ: Criminology, John Widemans Bro EssaySUDAN III TESTIntroduction: Sudan III test detects the hydrocarbon groups that are remainingin the molecule. Due to the fact that the hydrocarbon groups are nonpolar, andstick tightly together with their polar surroundings, it is called a hydrophobicinteraction and this is the basis for the Sudan III test. If the end result isa visible orange, it tests positive. Material: scissorsdeionized watermargarineSudanIII solution petri dishstarchethyl alcoholforceps lead pencilcream5 barrel pipettes filter papercooking oilblow dryerProcedure: 1.Cut a piece of filter paper so it would fit into a petri dish. 2. Used a lead pencil, and marked W for water, S for starch, K for cream, Cforcooking oil and M for margarine. Draw a small circle next to eachletter for thesolution to be placed. 3.Dissolve starch, cream, cooking oil andmargarine in ethyl alcohol. 4.Used a barrel pipette for each solution, added asmall drop from each solution tothe appropriate circled spot on the filter paper. 5.Allowed thefilter paper to dry completely using a blow dryer. 6.Soaked the paper in theSudan III solution for 3 minutes. 7.Used forceps to remove the paper fromthe stain. 8.Marinated the paper in a water bath in the petri dish, changedwater frequently. 9.Examined the intensity of orange stains of the 5 spots. Record in the table below. 10. Completely dried the filter paper, andwashed the petri dish. Data: Sudan III Test ResultsFilter paper:Discussion: The results indicate that the Sudan III test was sucessful. Waterand starch definitely doesnt contain any fatty substances. Cream and cookingoil no doubtedly does contain lipids. It was surprising to find that margarinedoesnt contain any fat. BIURET TESTIntroduction: In a peptide bond of a protein, the bond amino group issufficiently reactive to change the Biuret reagent from blue to purple. Thistest is based on the interaction between the copper ions in the Biuret reagentand the amino groups in the peptide bonds. Materials: 6 test tubesegg white solutionstarchsolution6 toothpicks rulerchicken soupsolutiongelatin6 parafilm sheets permanentmarkerdeionized watersodium hydroxide labelsglucose solutioncopper sulfateProcedures: 1.Used 6 test tubes, and labeled them at 3cm and 5cm from thebottom. Labeledeach #1 to #6. 2.Added egg white solution to the 3cm mark of thefirst tube, chicken soup solutionto the 3-cm mark of the second tube, water to the 3 cm mark of the thirdtest tube,glucose solution to the fourth, starch to the fifth, and gelatin to thesixth, all at the3 cm mark. 3.Added sodium hydroxide to the 5 cm mark of each tube andmix with 6 differenttoothpicks. 4.Added 5 drops of Biuret test reagent, 1% copper sulfate,to each tube and mixby placing a parafilm sheet over the test tube opening, and shakevigorously. 5.Held the test tubes against a white piece of paper, and recordedthe colors andresults. Discarded the chemicals, and washed the test tubes. Data:Biuret Test ResultsDiscussion: The Biuret test seemed to have been successful. Glucose and starchare both carbohydrates, while water has no proteins. Egg white definitely hasproteins, and so does gelatin. Chicken soup had a hint of protein content. Unknown Chemical # 143Introduction: By performing the Benedicts Test, the Iodine Test, the Sudan IIITest, and the Biuret Test, chemical #143 should be identified. Materials: materials from the Benedicts Testmaterials from the SudanIII Test Materials from the Iodine Testmaterials from theBiuret TestProcedures: 1.Performed the Benedicts Test, and recorded results. 2. Performed the Iodine Test, and recorded results. 3.Performed the Sudan IIITest, and recorded results. 4.Performed the Biuret Test, and recorded results. Data: Properties of Chemical #143chemical #143 was a white powderish substance. Conclusion: After ruling out the obvious wrong substances from the list likeground coffee, egg white and yolk, table sugar and salt, syrup and honey, thesmall amount of proteins was taken into factor. That also eliminated powderedskim milk, and soy flour. The low, or none fat content ruled out some morechoices like enriched flour. The only choices left was corn starch, glucose,and potato starch. Because of the low reducing sugar, glucose can be ruled outalso. .u3957fe602a831ad9da87680c47a91a39 , .u3957fe602a831ad9da87680c47a91a39 .postImageUrl , .u3957fe602a831ad9da87680c47a91a39 .centered-text-area { min-height: 80px; position: relative; } .u3957fe602a831ad9da87680c47a91a39 , .u3957fe602a831ad9da87680c47a91a39:hover , .u3957fe602a831ad9da87680c47a91a39:visited , .u3957fe602a831ad9da87680c47a91a39:active { border:0!important; } .u3957fe602a831ad9da87680c47a91a39 .clearfix:after { content: ""; display: table; clear: both; } .u3957fe602a831ad9da87680c47a91a39 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u3957fe602a831ad9da87680c47a91a39:active , .u3957fe602a831ad9da87680c47a91a39:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u3957fe602a831ad9da87680c47a91a39 .centered-text-area { width: 100%; position: relative ; } .u3957fe602a831ad9da87680c47a91a39 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u3957fe602a831ad9da87680c47a91a39 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u3957fe602a831ad9da87680c47a91a39 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u3957fe602a831ad9da87680c47a91a39:hover .ctaButton { background-color: #34495E!important; } .u3957fe602a831ad9da87680c47a91a39 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u3957fe602a831ad9da87680c47a91a39 .u3957fe602a831ad9da87680c47a91a39-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u3957fe602a831ad9da87680c47a91a39:after { content: ""; display: block; clear: both; } READ: Geology a science of lies EssayThe starch content of substance #143 was very high. The protein content wasaround the 10% range, so potato starch would be a better guess then corn starch. But corn starch contained only a trace of fat when potato starch contained 0.8%. But 0.8% is very insignificant. The most educated guess to what chemical #143is potato starch.
