Osmosis in Potatos Essay Example For Students

Osmosis in Potatos Essay 18. 11. 01Osmosis InvestigationTo investigate the effects of changing the sucrose concentration on osmosis in plant cells. Water passes into cells through a special type of diffusion called osmosis. Water molecules diffuse through the membrane from a weak solution into a strong solution until the concentration is the same on both sides. A membrane that allows only certain molecules to pass through is called a semi-permeable membrane. In a plant, water passes from a weak cell sap solution to an adjoining cell with a stronger solution, as water passes in, the volume of the sap vacuole increases. When a full sap vacuole presses against the cell wall, it is said to be turgid. If water that is lost is not replaced the sap vacuole shrinks and pulls on the cell wall, the cell becomes flaccid; this is known as plasmolysis. In the cells shown below, water molecules will diffuse from the turgid cell into the flaccid cell, until the cells contain equal concentrations of cell sap. I intend to use potatoes for my investigation because these are sufficiently large, to enable all cores to be taken from the same potato, which will assist in ensuring a fair test. The concentration of sap in the sap vacuole of a potato cell is approximately 10% 15%. I intend to place a predefined weight of potato cells (0.15g) in varying concentrations of sucrose solution (0%, 20%, 40%, 60%, 80%), to see the effects of osmosis in the cells of a potato in varying levels of sucrose solution. The potato cores will be prepared, weighed and then placed in the solution and left for a certain amount of time, they will then be removed, re-weighed and the difference in weights calculated and plotted, and a conclusion reached. I have done some preliminary work into osmosis in potato cells. I weighed six potato cores, and then put three into sucrose solution and three into distilled water. After 25 minutes, I removed the potato cores from the solutions and re-weighed them. I discovered that the three in water had increased in mass and the three in sucrose had decreased in mass. This decrease was due to osmosis. I therefore predict that the potato cores in distilled water will increase in mass because the water molecules will diffuse from the solution into the sap vacuoles of the cells in the core. The water molecules will diffuse across the semi-permeable membrane, because the sucrose concentration is higher in the sap vacuole than in the distilled water. This is shown by the diagram (below left), water molecules enter the sap vacuole of the cell due to osmosis, and make the cell turgid. However, the potato cores in sucrose solution will lose water molecules to the sucrose solution, causing the sap vacuole to shrink and the cell to become flaccid. The water molecules will diffuse because the sucrose solution has a higher concentration than the cell sap. As there are varying concentrations of sucrose solution, I think that the solution with the least concentration will have the cores which lose the least mass; and the solution with the strongest concentration will have the cells which lose the most mass. I think this will occur because the larger the difference in the osmotic pressure, the faster the osmotic diffusion will proceed. A measuring cylinder was taken, and filled with 20ml of distilled water, distilled water was used, as it contained no impurities which could have caused anomalous readings. This water was transferred into a boiling tube, which was labelled and then placed in a boiling tube rack. The above steps were repeated twice, so there were three boiling tubes, each with 0% concentration of sucrose. The measuring cylinder was dried and 4ml of saturated sucrose solution was added, this was emptied into a boiling tube and then 16ml of distilled water was measured into the measuring cylinder and then added to the boiling tube to give a 20% concentration of sucrose. (It was decided that saturated sucrose solution could be taken as 100%, for the purposes of this experiment.) This boiling tube was then labelled, and placed in the rack, and the above steps repeated twice. The above steps were repeated until there were 15 boiling tubes; 3 with 0% sucrose concentration, 3 with 20%, 3 with 40%, 3 with 60% and 3 with 80%. There were three of each solution to enable three readings from each level of sucrose concentrationto be made, and therefore an average reading could be calculated. .uc9d4db71086914764d6b76c03813d5b5 , .uc9d4db71086914764d6b76c03813d5b5 .postImageUrl , .uc9d4db71086914764d6b76c03813d5b5 .centered-text-area { min-height: 80px; position: relative; } .uc9d4db71086914764d6b76c03813d5b5 , .uc9d4db71086914764d6b76c03813d5b5:hover , .uc9d4db71086914764d6b76c03813d5b5:visited , .uc9d4db71086914764d6b76c03813d5b5:active { border:0!important; } .uc9d4db71086914764d6b76c03813d5b5 .clearfix:after { content: ""; display: table; clear: both; } .uc9d4db71086914764d6b76c03813d5b5 { 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; } .uc9d4db71086914764d6b76c03813d5b5:active , .uc9d4db71086914764d6b76c03813d5b5:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uc9d4db71086914764d6b76c03813d5b5 .centered-text-area { width: 100%; position: relative ; } .uc9d4db71086914764d6b76c03813d5b5 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uc9d4db71086914764d6b76c03813d5b5 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uc9d4db71086914764d6b76c03813d5b5 .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; } .uc9d4db71086914764d6b76c03813d5b5:hover .ctaButton { background-color: #34495E!important; } .uc9d4db71086914764d6b76c03813d5b5 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uc9d4db71086914764d6b76c03813d5b5 .uc9d4db71086914764d6b76c03813d5b5-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uc9d4db71086914764d6b76c03813d5b5:after { content: ""; display: block; clear: both; } READ: Judge Declares Microsoft A Monopoly EssayA potato from the Desiree family was taken, a tile was put on the bench and a core remover was used to take fifteen cores from the potato. All cores were taken from the same potato to help ensure a fair test. Safety precautions were put into practise. We used a tile on the bench so that the bench would not be damaged, and were careful not to push the corer into our hands. Boiling tubes were held safely in racks. The cores were then sliced up on a new tile using a scalpel, until they were all approximately the same length and weighed using a top-pan balance to check that they all weighed in the region of 0.65g. The cores were then put into the solutions in the boiling tubes, and a stopwatch was started. The cores were started with two minute intervals between each start time to allow suffiicient time when they were finishing to be weighed and disposed of. If this time had not been allowed, some cores would have had more time in the solutions than others causing an unfair test and a false conclusion. After one hour, the potato cores were removed, dried on a paper towel to remove any excess surface water and re-weighed on the top-pan balance. The results were noted in a table and the difference in mass was calculated by dividing the final weight by the original weight, multiplying this by one hundred, and then calculating the difference between the number and one hundred. When all the differences in mass had been calculated, they were plotted on a graph. The apparatus was set out as shown below;A total of fifteen measurements were made during the investigation, three for each of the sucrose concentrations. This was undertaken to help improve the reliability of the results and prevent any anomalous results giving a false conclusion. On the table below, the average mass lost/gained for each sucrose concentration has been calculated. Sucrose ConcentrationBefore (g)After0.630.74+ 170.640.77+ 200.690.81+ 17+180.690.66- 40.670.63- 60.690.67- 3-40.680.55- 190.640.52- 190.690.55- 20-190.640.48- 250.650.50- 230.640.49- 23-240.660.47- 290.670.49- 270.660.48-28-28The potato cores left in distilled water have increased in size; they were very firm or turgid, water had diffused into the potato cells by osmosis. The potato cores left in concentrations of sugar solution have decreased in size, they were very soft or flaccid, and water had diffused out of the potato cells by osmosis. From the results of this investigation, the conclusion may be drawn that the higher the level of sucrose concentration, the more rapidly osmosis takes place. The bar graph above compares the mass difference at the different levels of sucrose concentration. From this graph, we can see that as the sucrose concentration increases, the mass percentage decreases. When this is shown on a line graph, we find that there is a correlation between the results, supporting the conclusion that the stronger the concentration of the solution outside the cell, the faster plasmolysis occurs. The conclusion of this investigation supports the original hypothesis that the potato cores in distilled water will increase in mass and that the potato cores in sucrose solution will lose mass. Also, the solution with the lowest sucrose concentration will have the cores which lose the least mass, and the solution with the strongest sucrose concentration will have the cells which lose the most mass. I think that this investigation went well and that the results were fairly accurate. There were a few anomalous results, but because several readings at each concentration were done, these anomalous results did not disrupt the overall graph or the conclusions. The anomalous results were probably caused by a difference in the surface area of the cores which was due to imprecision during the cutting procedure. If this experiment was repeated, or a similar one undertaken, greater accuracy during cutting could probably prevent these anomalous readings occurring. I have several proposals for further experiments to provide additional evidence for my conclusion. I would like to undertake another experiment with sucrose concentrations at 5% intervals from 0% to 100%. I would like to do this as I feel it would provide a better and more reliable set of results and a more justified conclusion. When there are more concentrations the shape of the curve shape can be seen more clearly, I suspect th at at the lower concentrations of sucrose the graph falls more steeply, flattening off at higher concentrations. I would also like to conduct an investigation, in conjunction with this experiment, to calculate the concentration of sap within the vacuole. To do this, I would find between which parameters the curve crosses the x-axis of sucrose concentration and retest at every 1% between these two parameters until I have found the concentration which contains a core that neither gains nor loses mass. This osmotic concentration would be the equivalent of the sap in the vacuole. .u9b7e0de969083a5183f6335b05e83b35 , .u9b7e0de969083a5183f6335b05e83b35 .postImageUrl , .u9b7e0de969083a5183f6335b05e83b35 .centered-text-area { min-height: 80px; position: relative; } .u9b7e0de969083a5183f6335b05e83b35 , .u9b7e0de969083a5183f6335b05e83b35:hover , .u9b7e0de969083a5183f6335b05e83b35:visited , .u9b7e0de969083a5183f6335b05e83b35:active { border:0!important; } .u9b7e0de969083a5183f6335b05e83b35 .clearfix:after { content: ""; display: table; clear: both; } .u9b7e0de969083a5183f6335b05e83b35 { 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; } .u9b7e0de969083a5183f6335b05e83b35:active , .u9b7e0de969083a5183f6335b05e83b35:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9b7e0de969083a5183f6335b05e83b35 .centered-text-area { width: 100%; position: relative ; } .u9b7e0de969083a5183f6335b05e83b35 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9b7e0de969083a5183f6335b05e83b35 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9b7e0de969083a5183f6335b05e83b35 .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; } .u9b7e0de969083a5183f6335b05e83b35:hover .ctaButton { background-color: #34495E!important; } .u9b7e0de969083a5183f6335b05e83b35 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9b7e0de969083a5183f6335b05e83b35 .u9b7e0de969083a5183f6335b05e83b35-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9b7e0de969083a5183f6335b05e83b35:after { content: ""; display: block; clear: both; } READ: Karl Marx Persuasive EssayAs an extension to this investigation, I would run two experiments in parallel.

Carol Anne Duffys Adultery (2024 words) Essay Example For Students

Carol Anne Duffys Adultery (2024 words) Essay Carol Anne Duffys AdulteryCarol Anne Duffys poem Adultery is structured in a traditional andstraightforward way. It is comprised of eleven verses each with the commonfour lines, which consist of between four and nine words. This makes the poemnot particularly striking at the first look, before it is read. The typographydoes not attract the readers attention, this is probably because Duffy wants thereader to concentrate on the language, and is not concerned with the shape thatthe lines form, or how they relate to the themes of the poem. RHYME AND RHYTHMDuffy does not seem particularly interested in rhyme in this poem, and probablydecided before writing it that she did not want any. Therefore rhyme has beenavoided, as has a regular, repetitive rhythm. I think that Duffy wants to allowthe language to speak for itself, without getting tangled up in rhyme and rhythmschemes, and having to change what she wants to say in order to make it fitthese limitations. She also wants to avoid losing the impact of the poem. Thishas much to do with the language used, poetic devices, and very often, the lackof rhythm, seen clearly in the first verse when she writes: Guilt. A sick,green tint The caesura breaks up the line, splitting it into two. If she werewriting within the barriers of a specific rhythm, she would probably be tempted,and perhaps compelled to, split this line exactly in half, in order to balanceit and keep the structure. This would not have the same effect. The caesura isused as dramatic device, implying that the poem is intended to be read out loud. The break makes the reader pause, giving the first word a larger impact as it isisolated from the rest of the text. It also does the same for the followingsentence, and as it is on the end of the verse, there is a natural pause here aswell, giving this line impact and power. Seeing as it also highlights a keytheme in the poem, guilt, it is also an important line as it tells the reader alittle about what to expect, and also raises their interest and expectations,Guilt? Why? Who? LANGUAGE Duffy uses language very effectively in this poem. Shewants to create a specific atmosphere and then build on it, creating characters,situations and emotions as she does so. She wants an atmosphere of sleazinessand seediness, but wants it to sound exciting, dangerous and seductive. She alsoexamines the harm that the situations cause. The first verse (or stanza) ispacked with intrigue, mystery, excitement and questions. Wear dark glasses inthe rain, demands the first line, and the reader gets ideas of disguise. Itgoes on to mention unhurt and bruise dark glasses to hide a blackeye? Maybe not, another glance at the title, Adultery, suggests somethingelse sado-masochism? Then comes the guilt, as mentioned above, andreader knows she is talking about a sexual affair but who? What? Where? Wewant to know more. The second verse builds on the sexual intrigue with mentionsof hands can do many things, and money tucked in the palms suggestsprostitution, as well as wash themselves maybe implying that they feeldirty? Duffy is building an atmosphere which is sexually charged and filled withriddles and ambiguous comments, daring the reader to assume a sexually link. Thenext verse features the line: You are naked under your clothes all day,another sexual connotation, perhaps implying that the clothes are a disguise,and all day the character does something which is not really them, andunderneath they are different, naked suggests vulnerability. There is alsobrings you alone to your knees and m ore, more, whichcould suggest oral sex, while the repetition shows that Duffy considers this themost important word of the line, demanding it stands out, and it could suggestan unsatisfied sexual appetite, or description of the frequency of thecouples meetings. Dishonesty is mentioned with deceit and Suck a liewith a hole in it. This could be a more explicit reference to oral sex, ormore obscurely, Polo mints, the mint you suck with a hole in it. Duffy could besaying that the lies are sweet, addictive and refreshing compared with a mundanelife, like Polo mints; she could mean that the lies come as easily as sweetsfrom a packet, although probably not. Or perhaps the key is in the next line:On the way home from a lethal thrilling night. Maybe the character ismulling over what the excuse will be to the spouse, how he/she will lie theirway out of where they have been, but the lie will always be flawed as it is nottrue hence the hole. The lethal also brings a touch of danger to theatmos phere. Duffy does not want the reader to be comfortable with this deceit orthe situation as a whole. We know it is sordid, and now we know it could be abit hazardous. Duffy continues with up against a wall, faster, an obviousreference to the e night theyve just had, with fast exciting sex quickgratification. The last line of this verse: unpeels to a lost cry. Youre abastard. The caesura breaks up the line, balancing it, and giving greaterimpact and significance to the second half. The colloquialism bastard isused for several reasons. It has a big impact, surprising the reader, andshocking a minority, who arent used to taboo words in poetry. This gives itmore power it is swear word, and is offensive. Duffy could have saidYoure a bad person, but this is dead, lame, and ineffective. It is alsomore emotional, as bastard is more dramatic than bad person and sohas more feeling in it. It is likely that Duffy is revealing what the spousesreaction would be to the news that his/her wife/hus band is having an affair. Ifnot then the adulterer is imagining what their spouse would say, and is callinghim/herself a bastard. It is unlikely that Duffy herself is calling theadulterer a bastard. Firstly Duffy does not appear to pass judgment on thecharacters in the rest of the poem, she lets their actions and feelings speakfor themselves. Secondly, Duffy would probably realise that it is moreinteresting to hear another characters opinion, than her own, especially whenshe has focused on what the characters are thinking in the rest of the poem. .u2d7f0c17bfd8949d2ea4ba7c878aa51b , .u2d7f0c17bfd8949d2ea4ba7c878aa51b .postImageUrl , .u2d7f0c17bfd8949d2ea4ba7c878aa51b .centered-text-area { min-height: 80px; position: relative; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b , .u2d7f0c17bfd8949d2ea4ba7c878aa51b:hover , .u2d7f0c17bfd8949d2ea4ba7c878aa51b:visited , .u2d7f0c17bfd8949d2ea4ba7c878aa51b:active { border:0!important; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .clearfix:after { content: ""; display: table; clear: both; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b { 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; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b:active , .u2d7f0c17bfd8949d2ea4ba7c878aa51b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .centered-text-area { width: 100%; position: relative ; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .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; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b:hover .ctaButton { background-color: #34495E!important; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b .u2d7f0c17bfd8949d2ea4ba7c878aa51b-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u2d7f0c17bfd8949d2ea4ba7c878aa51b:after { content: ""; display: block; clear: both; } READ: Performance analysis of Murder at the Manor EssayAltogether, Duffy is revealing some of the emotions involved with adultery. There is also the matter of whether the adulterer is male or female. Bastard is traditionally an insult towards men, and it is unlikely thatDuffy would purposely confuse the reader in regard to the gender of the maincharacter, especially when their actions and thoughts are so vital to the poem. This does not necessarily mean that the adulterer is male. The referencesearlier to oral sex implied that the adulterer was female, but I could be wrongabout those, or maybe Duffy is saying that person the adulterer is having anaffair with is a bastard hence a female adulterer. With the oral sexreferences in mind, presuming they are correct, it suggests that the affair ishomosexual, but if this were the case then Duffy would almost certainly say itin more explicit terms, as on first read this is not apparent, and Duffy cannotwant her poem to be that misunderstood. The next verse begins: Do it do it doit. Sweet darkness Duffy is using poetic devices to convey the mood andatmosphere she wants to create. The caesura again breaks the line in two givinga big impact and significance to both halves as the readers pauses for effect. The repetition shows that the phrase do it is important and needs to beemphasized again and again, or perhaps it is describing how they do itagain and again a possible sexual reference. The lack of punctuation conveysthe speed and urgency. Sweet darkness is almost an oxymoron; we are usedto thinking of darkness as spooky, scary and hiding dangers, and to think of itas sweet seems to be a contradiction in terms, it isnt really, but Duffyknows that this impression will be given. She could be talking about the loversmeeting in the darkness, or darkness hiding their sins, but either way, the factthat it appears to be an oxymoron draws the readers attention to it, as does thecaesura. Duffy then returns to sexually ambiguous phrases like how you arewanted, which way, now, and pay for it in cash this must be referringto desire in the former quotation and probably prostitution in the latter. However, Duffy never explicitly writes about prostitution, just hints at it inorder to increase the sexual tension and condense the atmosphere of seediness. Duffy goes on to describe how the affair is taking its toll on the marriageand conscience of the adulterer. The life which crumbles like a weddingcake. Duffy uses a simile to describe how the life is being eroded, bycomparing it to a crumbling wedding cake, reminding that the adulterer ismarried, and that the marriage must also be splintering. The seventh verse isinteresting: Paranoia for lunch; too much to drink, as a hand on your thightilts the restaurant. You know all about love, dont you. Turn on yourbeautiful eyes The annotations show all the poetic devices that Duffy uses,mostly in order to increase the mood of the poem and convey the theme. In thenext verse Duffy uses an interesting image: the slicing of innocent onionsscalds you to tears. I do not know what Duffy is trying to say to the readerhere, but there are several possibilities. The adulterer has returned to thehousehold chores for the family, and is crying because he/she feels bad abouthow he/she has betrayed the fami ly, and is reminded of this by the return to theold routine; or possibly the innocent onions represent the innocentmembers of the family that the adulterer has hurt this would be theslicing and the realisation of this has made the adulterer cry, justlike cutting onions would. Duffy is telling the reader that the adulterer feelsremorse that the family has suffered for her affair, and this changes theatmosphere. It appears that in these verses the poet is describing what happenswhen the adulterer returns to the family home, he/she sleeps in a maritalbed, Duffy is pointing this out so deliberately to highlight the fact thathe/she has recently been sharing another bed, an extra-marital one. Thetarnished spoon of your body stirring betrayal Duffy uses a metaphor toexplain that the adulterer feels dirty due to his/her actions, and is acutelyaware of how he/she has let down the family and betrayed the spouse. The readerfeels that the adulterer regrets their actions, and is now dealing w ith theconsequences, which could be severe as he/she has to send dumb and explicitflowers on nobodys birthday to try to win over the partner again andapologise. If the partner hasnt found out then the adulterer is probablysending the flowers just out of guilt. However, the last verse implies that thepartner does know whats been going on, as they appear to have an argumentabout it: You did it. What. Didnt you. Fuck. Fuck. No Duffy doesnot explicitly show that it is dialogue by using inverted commas, but thelanguage suggests it is. The partner has just discovered what is going on and isconfronting the adulterer. The colloquialism is again used to give the linepower, impact, and the ability to shock, as *censored* is generallyconsidered to be the most taboo word in the English language. It is shows thatthe this is very emotional. The characters are using strong languagebecause they have very strong feelings and are very upset. They both want to getacross the power of what they are feel ing, and the lack of question marks-?-show that they are not calmly asking each other questions, but are speaking instatements You did it, didnt you., rather than You did it,didnt you?. This also implies that they are shouting at each other. Thisis usually shown in either capital letters, italics, or bold type, but Duffyagain does not want to be so explicit. She wants the reader to have to read theverse a few time through to understand it, as this will make them concentratemore and focus on what is being said. Throughout this poem Duffy is building upatmosphere. She uses language and poetic devices to create a mood, and thenchanges the mood, thereby moving the story on.

The Afrikaans Medium Decree

The Afrikaans Medium Decree The South African Minister of Bantu Education and Development, MC Botha, issued a decree in 1974 that made the use of Afrikaans as a medium of instruction in black schools compulsory from Standard 5 onwards [from the last year of primary school to the last year of high school]. The African Teachers Association (ATASA) launched a campaign against the policy, but the authorities implemented it anyway. Northern Transvaal RegionRegional Circular Bantu EducationNorthern Transvaal (No. 4)File 6.8.3. of 17.10.1974To: Circuit InspectorsPrincipals of Schools: With Std V classes and Secondary SchoolsMedium of Instruction Std V - Form V1. It has been decided that for the sake of uniformity English and Afrikaans will be used as media of instruction in our schools on a 50-50 basis as follows:2. Std V, Form I and II2.1.

Forms III, IV and VAll schools which have not as yet done so should introduce the 50-50 basis as from the beginning of 1975. The same medium must be used for the subjects relate d to those mentioned in paragraph 2 and for their alternatives. ...Your co-operation in this matter will be appreciated.(Sgd.) J.G. ErasmusRegional Director of Bantu EducationN. Transvaal Region ... The Deputy Minister of Bantu Education, Punt Janson, said: No, I have not consulted the African people on the language issue and Im not going to. An African might find that the big boss only spoke Afrikaans or only spoke English. It would be to his advantage to know both languages. Another official was quoted as saying: If students are not happy, they should stay away from school since attendance is not compulsory for Africans. The Department of Bantu Education said that because the government paid for black education, it had the right to decide on the language of instruction. In fact, only white education was totally subsidized by the government. Black parents in Soweto paid R102 (an average months wages) a year to send two children to school, had to buy textbooks (which were issued free in white schools), and had to contribute towards the cost of building schools.

Persuasive paper - Essay Example A number of researchers have suggested negative advertisement or campaign is the standard in all political scenes, moderated by the liveliness of a competition. Running negative advertisements is among the most utilized techniques used when attacking a competitor’s opinion, record or personality. There are two types of advertisements employed during negative political advertising: contrast and attack. This paper is about negative political advertising in the Dominican Republic and my views against the advertisements. Contrast advertisements are made up of details on the opponent and the candidate. The detail about the candidate is definite while details about the competitor is damaging. Contrast advertisements contrast and compare the candidate with the competitor combine the definite information about the candidate with the damaging information of the competitor. Because contrast advertisements are required to contain positive or definite information, contrast advertisements are perceived as less destructive to the political activities than attack advertisements. On the other hand, attack advertisements concentrate solely on the damaging features of the competitor. In addition, there is no positive information in an attack advertisement, whether it is about the competitor or candidate. ... Popular negative campaign styles include depicting a competitor as dishonest, a danger to the country or as soft on law breakers (Ansolabehere and Iyengar 27). One of the most popular negative political advertisements is claiming the opponent is using a negative political advertisement. The negative political advertisements also constitute dirty tricks. These constitute secretly running political advertisements that contain destructive information. This method does not require a lot of money and also segregates a candidate from backlash. Nonetheless, the leaked information should be solid enough to draw media and people’s attention. In contrast, if the truth is found out it can extensively destroy a campaign. Negative political advertisement also constitute giving the competitor’s unit untrue information wishing they will respond and humiliate themselves. Frequently, a political campaign will employ external groups to air negative political advertisement, for example, l obby groups. These may be presumed as emerging from a neutral area, and if the claims turn out to be untrue, the attacking participant will not face damages if the connections cannot be established. Negative political advertisements can be made by substitutes. These negative political advertisements can address issues like violence, fraud, or other social evils against a competitor (Calvert 15). I oppose negative political advertisements because while it prompts the source of support, it can estrange undecided and centrist voter form the political practice. This will radicalize politics and lessen voter attendance. The effect of negative political advertisements is a larger image prejudice of the contenders and larger attitude divergence. In

In many circumstances, motivated employees are committed to the improvement of the working environments because they develop a sense of ownership to the activities of the company (Nyp, 2007). On the other hand, creating satisfaction mood in employees ensures that all the employees can protect the properties of the company for which they are working and reducing the chances of the company making losses. Creating a positive working environment enhances retention of highly performing employees and builds their loyalty to the management and the administrators of the company. In a company that allows employees freedom, growth and interactive platforms for doing their day to day activities, highly performing workers are likely stay for long. Employees are likely to stay because they feel that the company for which they work values their services by creating an environment for improvement of skills and refreshing their bodies after a period of continuous work.
