Explain why Act 2. Scene 2. is a turning point in the play for Macbeth and Lady Macbeth Essay Example for Free

Explain why Act 2. Scene 2. is a turning point in the play for Macbeth and Lady Macbeth Essay Explain why Act 2. Scene 2. Is a turning point in the play for Macbeth and Lady Macbeth. How should the actors playing these characters behave to show the audience what they are feeling? In the First Act we learn that Macbeth is thought of as a very noble, loyal, brave man. For brave Macbeth O valiant cousin, worthy gentlemen! Macbeth was victorious in a battle on behalf of the kingdom and gets lots of praise from the king, and the other soldiers, and unknown to him is soon be given the title, Thane Of Cawdor. Banquo and Macbeth are travelling home and they came across 3 witches. These witches prophisize that Macbeth will become Thane of Cawdor and that soon after he will become king. All hail Macbeth! Hail to thee, thane of Cawdor! All hail Macbeth! Thalt shalt be King hereafter. Macbeth doesnt pay to much attention to them and continues on with his journey, when he returns home, he finds out that the King is coming to stay with him and Lady Macbeth in their castle. Macbeth then finds out of the title and tells Lady Macbeth of the three witches prophesies, and then Lady Macbeth starts to hatch a plan. Macbeth was so horrified of the idea of killing Duncan because in those days, people believed in something, which was called the divine right of kings. Which meant that they believed the king to have been chosen by god. So an attack on King Duncan would have been considered sacrilege. In Act one, Macbeth comes across as brave and loyal, but if he goes through with the murder, he will be forever looking over his shoulder, he will have to watch what he says and does, because he could be found out. This would change his character entirely. Macbeth has to realise that there can be no going back once the murder has been committed. James 1 would have understood and believed in the divine right of kings, so when the play was being written, including it would have been more interesting as the play was originally wrote for James 1, who was king at the time. Scene 2 has to be the most violent part of the play although we dont actually see the murder in the written play, it is only included in the film version, which we recently watched, directed by Roman Polantski. It is interesting that Macbeth kills King Duncan offstage, the scene could be written this way because Shakespeare wanted us to concentrate on Macbeths reaction to the murder, rather than the murder itself. Its a crucial part in the play as it the first of many murders. The murder takes place on the night of the Kings stay. Everything that happens in the play now is revolved around this scene. This scene is important because it not only features the murder scene. It is also the start of the falling apart of the relationship between Macbeth and Lady Macbeth. There is a lot of tension when we see Lady Macbeth pacing about nervously, waiting for Macbeth to come back. We also see Lady Macbeths softer side too when she says Had he not resembled my father as he slept, I had donet meaning if the King had not looked like her father she would have gone through with the murder herself. I imagine her to be looking quite sad at this point, yet nervous, for fear of still being caught. It reminds us that lady Macbeth still has some humanity because it might help the audience to understand why she does what she does at the end of the play. Lady Macbeth hears an owl screech while she is waiting for Macbeth and jumps, as she is clearly quite nervous even though earlier on in the play she says That, which hath made them drunk, hath made me bold. This is obviously not the case. Lady Macbeth may say this half-jokingly and holding the cup up near to her face, which she drinks it. When Macbeth comes to meet his wife they are both nervous, yet they seem excited to, as they dont speak in full sentences, its a short, sharp exchange of words. When , Now , as, I descended , Aye. His shows the audience that they are worried, nervous etc. They will at this maybe looking around them to see if there is anyone coming, or looking at each other trying to see what the other is thinking. Macbeth also still has hold of the daggers, which makes the tension in the scene increase. Macbeth cant seem to believe he has committed such a crime as he says, This is a sorry sight. He is also referring to his hands, which are covered in blood, Macbeth must have been putting his head in his hands at this point for him not to notice, therefore holding them up in front of his face. He cant seem to forget about the murder after this point. He seems obsessed with what he has done and almost in a hypnotising state of mind. Lady Macbeth, although in a way mocks him, she stays calm and says to him Go get some water and wash this filthy witness from your hands. Lady Macbeth is probably pushing him to the fountain and is keeping an eye on him, as so, they wont get caught. Macbeth knows that he might be able to get rid of the stain from his hands but not from his conscience. He says Not all Neptunes ocean can wash me clean. Lady Macbeth makes fun of Macbeth for dwelling on the murder and has a go at him for being a coward. Macbeth and his wife seem to lose a connection with each other and Shakespeare has made it obvious that Macbeth is the weaker of the two characters and his and Lady Macbeths relationship isnt going very well. He shows this by having Macbeth ramble on, and say long speeches. But Lady Macbeth stays in control, she acts almost evil and without a conscience. The play seems to build up more tension by Macbeth saying that he thought he had heard a voice saying Glamis hath murdered sleep, and therefore shall sleep no more: Macbeth shall sleep no more. This could be Macbeths imagination, or him hearing another of the witches prophesies. The knocking on the door startles Macbeth, as he knows now, this could tell whether his crime is about to be found out or not. Lady Macbeth again keeps her head amongst all of this, although nervous they will be discovered. Lady Macbeth quickly returns the bloodstained daggers to Duncans grooms, and goes one further and says, If he do bleed, Ill guild the grooms with Duncans blood, for it must seem their guilt. Shakespeare has her do this to make the audience aware of how much more confident than Macbeth, Lady Macbeth is. Whereas Macbeth is still in shock of the crime he had committed. Shakespeare conveys that Lady Macbeth and Macbeths relationship is slowly deteriorating, as Macbeth seems to be acting crazily and Lady Macbeth seems evil and calculating and in control of the situation. The knocking still carrying on, lady Macbeth appears annoyed and urges her husband, to his chamber, where they can hide and come across as innocent to the murder if it is discovered. Shakespeare has once again let Lady Macbeth take control. Shakespeare has cleverly used language and structure of sentences manages to create a lot of tension and excitement in this scene. He uses the right language in the right places to make the characters and the play really believable. Towards the end of the play Macbeth becomes overwhelmed by guilt and fear, he murders anyone he suspects might know. Eventually the heir to crown kills Macbeth, after Lady Macbeth has taken her own life as she is overcome by the guilt. King James and the rest of the Shakespearean audience would have wanted the murders and lies and drama, this is probably what they would have expected. Sacrilege was believed to have been punished by God. Macbeth and Lady Macbeth were the murderers so this would have added excitement; the witches added some eerieness and supernatural theme to the play. These are good choices for the play at that particular time, and it still makes it good today.

Women In Medieval Europe

Women In Medieval Europe I chose the topic of Women in Medieval Europe to write my essay about. I will attempt to provide some basic knowledge about how the lives of women were very difficult during this time. Some things that will be discussed are the submissions women had to give to men. To start this essay I ask a number of questions, the first one is as follows: What type of work did women do during this period? Women that were from poverty stricken homes would have to go out and work with their husbands to bring in more income because his alone was not enough to support their household due to women having multiple children. Women would help their husbands haul hay or plow fields. Poor women did not have shoes to wear so they walked around barefooted and during the winter they would not have any winter clothes to keep them warm so they would wrap themselves in sheets to protect them from the cold. They also took their children to work with them because they could not afford nannies like the wealthy class could. How was life different for wealthy women during this time? As with any culture having money always gives you more advantages. Although wealthy women had to obey the same things, such as not speaking unless you were spoken to or only if it was approved by a man first and obey the men. Women of higher classes had jobs to do as well some would have to help run their businesses and if their multiple businesses or properties that the family owned then she would have to help her husband over see them too. Of course they could afford to hire workers but there were somethings that had to be handled by them personally. If the womens husband passed away, then everything was left entirely up to her to take care of. Wealthy women had more advantages even when it came to caring for their children. They had the luxury of hiring nannies for this job. The nannies would even breast-feed their babies for them. Why would women in this time become a Nun? Women became nuns in this time because this was a way they could get an education and gain some rights. This was especially popular for the lower class women because this was their only hope of getting a proper education. Becoming a nun meant that she would have to be celibate and the chance of having children would be lost. By becoming a nun women grew their own crops and had their own house. With the education that was provided, they were also able to pursue careers. Many of the poor families that had multiple daughters would make their daughter become a nun because they could not afford to raise them and to ensure that they would get an education. The bad side of this was that once you became a nun it was forbidden for you to leave or have children. Back in this time it was said that a woman that could not or would not bear a mans child was of no use at all. What happened to unwed women during this time? Unmarried women that owned land or multiple properties were considered to have the same rights as men. But if and or when she did get married, then she was forced to give her husband all of her properties and she gave up her rights. Women that were not married could wear their hair down but the women that were married had to wear their hair in a linen wimple to cover her hair up because this showed sign of modesty. Women were not able to pick their husbands. Men were able to pick their wives at times. Marriages were very carefully arranged by family members. Marriages were not based on love or emotions. Families would try and arrange marriages between their daughters and sons based on economic factors. These factors would be if they had their own land, if they owned their business or if they come from a wealthy family. So once again money had a great deal to do with influences with other people. It was really a marriage of property and money that the church unified and the families would have a very large crowd of well known people to witness this occasion. This was commonly between the wealthy people but what about marriages between the poor women? The poverty stricken women and men normally married who they pleased because they had nothing to gain or lose. The legal age to get married in the medieval days was 12 for girls and 14 for boys. This was a common age to be married back then because of the expected life span. Due to lack of medical care and medicine, people died at a much younger age than they do today. There were very few reasons that the couple could get divorced. Some of the reasons they could get divorced were if they were not Christians, they were not of legal age, if they had previous promises to another person or the woman could not perform sexual relations. Women had to submit to their husbands whenever he desired for her to. Were there any powerful women during this time? One person could sum this question up and that is Joan of Arc. Joan of Arc was considered a heroic figure in France. She disguised herself as a boy to join the army and became one of the most famous leaders. Women were not allowed to join the army and that is the reason she disguised herself as a boy. Joan had said that she had visions from God and he was calling her to be a warrior. There were other famous women such as Hildegard of Bingen who was considered to be a very famous writer of sacred music in the middle ages, Christine de Pizan was a famous writer and feminist one of her more popular books were The Book of the City of Ladies and last but not least there was Lady Godiva, she was the woman famous for riding nude on a horse through the town of Coventry. She wanted to prove that the towns people were honorable and would not look at her being naked. There were a number of much respected Queens during this time, as well as a number of princesses. Final question that runs through my mind is was it really that bad for women? My answer would be yes it was extremely bad for women. Women had absolutely no rights at all. Any man in the family could tell her to do something and she had to do it. If she did not do what she was asked to do then she was badly beaten. It was said that a woman that did not obey was disobeying God. A woman had to give up her land and rights to the man she married. Also women were not even allowed to pick the person they were to marry. Imagine if it was the same way today! So many women are so outspoken and very independent that we couldnt even think about a man running our entire lives. Not only not being able to speak or do what we want to do but to be badly beaten just because we choose not to. Women were also very often accused of doing very awful things. Some of the accusations were practicing witchery; women would be burn at the stake for this. Conclusion: The conclusion for my essay is that with all of the research that I have done to see what the lives were like for women during the Medieval Period, I have found that their lives did seem extremely hard and unfair. To justify why this may have been, many would say Christianity. Eve was perceived as the trouble maker and then there was the impurity that many men thought women had because of menstrual cycles. While Christianity might have played a role as to why men thought they could treat women this way, it also provided protection for women as well. It did not allow divorce for any given reason (as it is today). It also did not allow the men to kill their wives. Sure they were able to beat them within an inch of their life but at least they did get to keep their life. There were some kings that treated women fairly and had a great deal of respect for them but there were not a lot of them. But this was well over a thousand years ago and a lot of things have changed since that time. I am personally, very grateful that they have changed!

Transition Elements And Coordination Compounds Biology Essay

Transition Elements And Coordination Compounds Biology Essay As we know, Manganese is found in the first row of transition metal with the electron configuration [Ar] 3d5 4s2. Besides that, Manganese has different type of oxidation states when it appears as a compound and the oxidation state is from Mn(-III) until Mn(VII). So, we know that the compounds of manganese range in the oxidation number have a different of 10 electrons. In the experiment 1, we prepare tris(acetylacetonato)manganese(III), Mn(acac)3 by using manganese(II) chloride tetrahydrate and potassium permanganate act as oxidation agent to oxidise manganese(II) chloride to acetylacetonemanganese(III). Manganese(III) acetylacetonate is an one- electron oxidant. Manganese(III) acetylacetonate is high spin. It has also a distorted octahedral structure. This distortion is due to the Jahn-Teller effect. (Absolute Astronomy, 2009). The structure of Manganese(III) acetylacetonate is shown as below:- (Source: Tcieurope.com) The equation is as follow:- MnCl2 + 4H2O Mn(H2O)4Cl2 Mn(H2O)4] Cl + 2HC5H7O2 + NaC2H3O2 Mn(C5H7O2)2 + NaCl + HC2H2O2 4Mn(C5H7O2)2 + KMnO4 + 7HC5H7O2 + HC2H3O2 5Mn(C5H7O2)3 + KC2H3O2 + 4H2O Furthermore, bis(acetylacetonato)oxovanadium(IV) is also known as Vanadyl acetylacetonate, VO(acac)2. As we know, it is a blue green complex. bis(acetylacetonato)oxovanadium(IV) has a vanadyl group, VO2+. The vanadyl group is bonded to 2 acetylacetonate anions and the structure of the compound is as follow:- This complex can be made from vanadium(IV) or vanadium(V). In our experiment, bis(acetylacetonato)oxovanadium(IV) was prepared from vanadium(V) oxide and the equation is as follow:- V2O5 + 2H2SO4 + EtOH 2VOSO4 + 3H2O + CH3CHO VOSO4 + 2HC5H7O2 + Na2CO3 VO(C5H7O2)2 + Na2So4 + H2O + CO2 (Absolute Astronomy, 2009) Besides that, both of the acetylacetonato (acac) groups of bis(acetylacetonato)oxovanadium(IV) are able to be exchanged with organic ligands having coordinating atoms of different potentialities. (Maurya, 2003) Both Manganese(III) acetylacetonate and bis(acetylacetonato)oxovanadium(IV) are bond with acetylacetonate which known as ligand. The precursor for acetylacetonate is acetylacetone with formula CÂ ­5H8O2. However, acetylacetonate is an anion. It can bind to corresponding cation but it very hard to exist as a free ion in solution. In addition, Cobalt is a hard, gray metal. It has a proton number 27. Besided that, there are two types of cobalt ions namely Co2+ and Co3+. First, Co3+ ion is more weaker than the Co2+ ion. However, the complex ion formed with higher oxidation state is more stable. ( Â °zmir Institute of Technology, n.d.). So that, Cobalt(III) complexes are kinetically inert. Co3+ can undergo a process known as ligand exchange reactions slowly which compared to Co2+ complexes. The cobalt(III) complexes are usually in octahedral shape. In the experiment, chloropentaamminecobalt(III) chloride is being synthesized. The structure is as follow:- (Source: Chemicalbook.com) The complex is prepared by the oxidation of ammoniacal solution of cobalt(II) salts by using hydrogen peroxide. The formula is as follow:- Co2+ + NH4+ + 1/2H202 → [Co(NH3)5H20]3+ [Co(NH3)5H20]3+ + 3Cl- → [Co(NH3)5Cl]Cl2 + H20 ( Â °zmir Institute of Technology, n.d.) Materials and Methods : Experiment one 5g of MnCl2.4H20 1.3g of NaC2H3O2.3H2O NaC2H3O2.3H2O Dissolved in 200cm3 of distilled water. 21cm3 of 2HC5H7O2 slowly added 1g of KMnO4 Present of two-phase layer Solution A added in with stirring Dissolved in 50cm3 of distilled water. 13g of NaC2H3O2.3H2O Solution B added in Solution A Solution B Dissolved in 50cm3 of distilled water. Heated with 60oC for 30 minutes Complex washed with acetone Solid complex filtered by suction Resultant solution was cooled with ice-cold water Experiment 2 Experiment 3 Recrystallise Results : For experiment 1, from the equation below, I can get the theoretical mass of the Mn(acac)3 solid complex by : Mn(H2O)4] Cl + 2HC5H7O2 + NaC2H3O2 Mn(C5H7O2)2 + NaCl + HC2H2O2 4Mn(C5H7O2)2 + KMnO4 + 7HC5H7O2 + HC2H3O2 5Mn(C5H7O2)3 + KC2H3O2 + 4H2O From the equation, we know that 1 mol of Mn(H2O)4] Cl = 1 mol of Mn(C5H7O2)2. So, 5 g of Mn(H2O)4] Cl = 0.0308 mol is also = 0.0308 mol of Mn(C5H7O2)2. From the second equation, 4 mol of Mn(C5H7O2)2 = 5 mol of Mn(acac)3 0.0308 mol of Mn(C5H7O2)2 = 0.0385 mol. Of Mn(acac)3 So, theoretical weight of Mn(acac)3 = 0.0385 mol X 252.938 g/mol theoretical weight of Mn(acac)3 = 9.7381 g The following shows the method to get our experimental weight: Weight of Sample tube 14. 8180 g Weight of Sample tube + solid complex , Mn(acac)3 18.7785 g So, the experimental weight of Mn(acac)3complexes were 3.9605 g Percentage yield of Mn(acac)3complexes we get was = 3.9605 g / 9.7381 g X 100 % = 40.67 % Next, Magnetic moment of Mn(acac)3complexes were calculated as follow : m = 0.9278g- 0.8193g = 0.1085g Ro= -33 L = 2.4cm R= 1165 (paramagnetic) CBal = 1 X(g) = [CBal X L X (R-Ro) ] / 109 X m X(g) of Mn(acac)3complexes = 2.65 X 10-5 So, Mn(acac)3complexes are paramagnetic FTIR Interpretation of IR spectrum for complexes will be written in discussion. For experiment 2, from the equation below, I can get the theoretical mass of the [Co(NH3)5Cl]Cl2 solid complex by : Co2+ + NH4+ + 1/2H202 → [Co(NH3)5H20]3+ [Co(NH3)5H20]3+ + 3Cl- → [Co(NH3)5Cl]Cl2 + H20 From the above equation, 1 mol of Co2+ = 1 mol of [Co(NH3)5H2O]3+ 12g of Co2+ = 0.0504 mol So 0.0504 mol of [Co(NH3)5H20]3+= 0.0504 mol of [Co(NH3)5Cl]Cl2 Theoretical weight of [Co(NH3)5Cl]Cl2 solid complexes = 0.0504 mol X 250.433 g/mol = 12.6218 g The following shows the method to get our experimental weight: Weight of Sample tube 14. 9285 g Weight of Sample tube + solid complex , 22.3723 g So, the experimental weight of [Co(NH3)5Cl]Cl2 solid complexes = 7.4438 g Percentage yield of [Co(NH3)5Cl]Cl2complexes = 7.4438 g / 12.6218 g X 100 % = 58.98 % Next, Magnetic moment of [Co(NH3)5Cl]Cl2complexes were calculated as follow : m = 0.9264g- 0.8207g = 0.1057g Ro= -36 L = 2.1cm R= -41 (dimagnetic) CBal = 1 X(g) = [CBal X L X (R-Ro) ] / 109 X m X(g) of [Co(NH3)5Cl]Cl2complexes = -9.9338 X 10-8 So, [Co(NH3)5Cl]Cl2complexes are diamagnetic FTIR For experiment 3, from the equation below, I can get the theoretical mass of the [Vo(acac)2(H2O)] solid complex by : V2O5 + 2H2SO4 + EtOH 2VOSO4 + 3H2O + CH3CHO VOSO4 + 2HC5H7O2 + Na2CO3 VO(C5H7O2)2 + Na2So4 + H2O + CO2 From the above equation, 1 mol of V2O5 = 2 mol of VOSO4 2g 0f V2O5 = 0.011 mol = 0.022 mol of VOSO4 2 mol of VOSO4 = 2 mol of VO(C5H7O2)2 Theoretical weight of VO(C5H7O2)2= 0.022 mol X 264.94 g/mol = 5.8287 g The following shows the method to get our experimental weight: Weight of Sample tube 14.8445 g Weight of Sample tube + solid complex , 18.5818 g So, the experimental weight of VO(C5H7O2)2= 3.7373 g Percentage yield of VO(C5H7O2)2= 3.7373 g / 5.8287 g X 100% = 64.12% Next, Magnetic moment of impure VO(C5H7O2)2 complexes were calculated as follow : m = 0.8880g 0.8244 g = 0.0636g Ro= -34 L = 2.5cm R= 72 (paramagnetic) CBal = 1 X(g) = [CBal X L X (R-Ro) ] / 109 X m X(g) of impure VO(C5H7O2)2complexes = 4.17 X 10-6 So, VO(C5H7O2)2complexes are paramagnetic Magnetic moment of pure VO(C5H7O2)2 complexes were calculated as follow : m = 0.8947g -0.8211 = 0.0736g Ro= -33 L = 2.3cm R= 144 (paramagnetic) CBal = 1 X(g) of pure VO(C5H7O2)2complexes = 5.53 X 10-6 FTIR Interpretation of IR spectrum for complexes will be written in discussion.

This FTIR can be used to identify different types of chemical bond which is either organic compound or inorganic compound. So no two different compounds will have same spectrum. However, FTIR may cause destructive to our sample compare to magnetic susceptibility which is non-destructive. Besides that, magnetic susceptibility can be group by paramagnetic, diamagnetic and ferromagnetic. Paramagnetic substance is those attracted by strong magnetic field but those repelled by magnetic field are diamagnetic substances. Besides that, we can also confirm the shape by using magnetic susceptibility. The Cobalt ion to form Chloropentaamminecobalt(III) chloride has 6 electron in d orbital. According to crystal field theory, if the complex is in octahedral shape, the electron can be arranged like below:- Low-spin high-spin eg eg t2g t2g If the complex is in tetrahedral shape, the electron are arranged as below:- t2g eg Magnetic Susceptibility for chloropentaamminecobalt(III) chloride is -9.9338 X 10-8 and it is diamagnetic. Only the low-spin octahedral shape shows diamagnetic properties, so the shape of chloropentaamminecobalt(III) chloride is octahedral. Furthermore, for tris(acetylacetonato)manganese(III), the Mn3+ ion has 4 electron in d orbital, and the arrangement in octahedral shape will as follows:- Low-spin High-spin eg eg t2g t2g For the arrangement in tetrahedral shape, the electrons are arranged as below:- t2g eg Magnetic Susceptibility for tris(acetylacetonato)manganese(III) is 2.65 X 10-5 and it is paramagnetic. So the shape of tris(acetylacetonato)manganese(III) is octahedral. However we cannot determine whether is low-spin or high-spin in this situation because we are not calculating the pairing energy for the complex. In addition, there is only one electron in d orbital for vanadium ion of bis(acetylacetonato)oxovanadium(IV). Magnetic susceptibility for it is 4.17 X 10-6 and it is paramagnetic. The shape is octahedral and the arrangement of electron is as follow:- eg t2g Acetylacetonate is delocalized and formed resonance structure as follow : The structure of Co(NH3)5Cl]Cl2 is as follow : The structure of [VO(ACAC)2] is as follow : Moreover, oxovanadium complexes act as insulin mimetics, nucleolytic and anticancer. To recognize insulin- mimetic complexes, a simple and fast in-vitro assay is developed. Besides that, an accurate assessment of the cells taken up of glucose, in-vitro assay with Ehrlich can be used. The oxovanadium complexes can cleave DNA without the present of hydrogen peroxide. Then, its nucleolytic efficiency is also greater but it is affected by the choice of buffer and pH. The oxovanadium complexes is also an anticancer agent against human ovarian cancer. Actually, I have acquired a lot of new knowledge among these three experiments. First, experiment one and two are easier to carry out compared to experiment three. This is because experiment one and two involved oxidation which Mn2+ was oxidized to Mn3+ ; Co2+ was oxidized to Co3+. Whereas experiment 3 involved reduction which reduced VO5+ to VO4+. At the beginning of each experiments, we heated up the sample in open air. It is easier to oxidize the compound than reduce the compound in the presence of oxygen. So, we need more time to heated the V2O5. During the first time of experiment three, I failed to get a blue color solid powder. This is because I heated the sample in the open air and I failed to control the heater. So, after the filtration process, I got a white solid powder. Therefore, I learnt from the mistake and during the second time I used reflux method. This time I can control the heating process well. The ethanol was not evaporated much. After filtration, I got quite a lot of blue solid powder. So, I knew that, for reduction process, we cannot heat the sample too quickly and heat too long. If we heated too long, most of the product will evaporate. Next, from the FTIR spectrum, I can observe that the spectrum from the first and third experiment are quite similar. This is because, the peak from the spectrum are mostly from the acetylacetonato (acac). However, spectrum from experiment two is quite different from other experiment because mostly the peaks come from Cl compared to other experiments. The percentage yield of the complexes from all the three experiment that I have calculate out was not so high. This is maybe due to the washing of the product with acetone, some of the product was dissolved and washed away. However, there are other factors which cause problem to our results. First, most of the heating plate we used cannot function well. I changed many heating plate during the experiment. Next, we have kept our half way done sample for more than 7 days. The results may not be so accurate anymore. Another factor maybe due to the volume and amount of the sample and other material we measure are not accurate. Our product may contain some impurities. However, some of the precaution was taken during the experiment. In these experiments, some of the chemical was corrosive and poisonous such as concentrated HCl and H2SO4. So, we poured the chemical carefully in the fume board. Next, before using any instrument, we read through the manual to understand the steps to function the magnetic susceptibility balance. We also taken down some important steps to function the FTIR spectrophotometer. I have asked some help from lab assistant on where to get the material for experiment. Conclusion : The percentage yield for tris(acetylacetonato)manganese(III) is 40.67%, chloropentaamminecobalt(III) chloride is 58.98% and (acetylacetonato)oxovanadium(IV) is 64.12%. For tris(acetylacetonato)manganese(III), the peak for two Mn-O bond are at the region approximately 678.1 cm-1 and 458.3 cm-1. For chloropentaamminecobalt(III) chloride, the peak for Co-N bond is at 669.2 cm-1 while Co-Cl bond is at 486.2 cm-1. For bis(acetylacetonato)oxovanadium(IV), the peak for V=O bond is at 997.4 cm-1 region. Magnetic Susceptibility for tris(acetylacetonato)manganese(III) is 2.65 x 10-5 and it is paramagnetic. Besides, Magnetic Susceptibility for chloropentaamminecobalt(III) chloride is -9.93x 10-8 and is diamagnetic. For bis(acetylacetonato)oxovanadium(IV), magnetic susceptibility for impure complex and pure complex are 4.17X 10-6 and 5.53X 10-6 respectively. They are paramagnetic.

Comparing Machiavellis Prince and Martha Stuart :: Comparison Compare Contrast Essays

Machiavelli's Prince and Martha Stuart    I believe Machiavelli's advice in The Prince was ideal for the rulers in 16th century Italy, because Machiavelli understood the motivation of most political men. Machiavelli based his theories on perfect examples throughout History. Machiavelli reverently believed his advice was essential for the uniting of Italy which was his principal desire.      Ã‚  Ã‚   Machiavelli states that in an ideal world, it is virtuous for a prince to be good. But in reality, princes who distance themselves from ethical concerns and do whatever it takes for the benefit of their states rule best. Therefore, it is better to be frugal than generous, cruel than loving, crafty than honest. Machiavelli's general rule is to be as good as circumstances allow, but be willing to resort to any means necessary for the good of the state. A prince must be willing to resort to evil if that is what it takes to overcome the change in fortune. Proper cruelty is done at one time and serves a specific purpose. Improper cruelty is repetitive and threatening to the citizens. A wise prince must be willing to practice proper cruelty in order to maintain power, but avoid improper cruelty so that his subjects do not feel hatred for him. Machiavelli emphasizes the need for the prince to win the support of the people. A feudal prince must be wise in controlling the nobles and keeping the people content.   A wise prince must not put off confrontations for another day. Even fortresses are useless if the prince does not have the support of his people.  Ã‚        Ã‚   Machiavelli makes it clear hypocrisy and deceit are legitimate methods in politics. It is not important for a prince to have good qualities; only appear to have them. The prince must have the characteristics of both the fox and the lion. The fox can recognize snares but cannot drive away the enemy while the lion can protect themselves but cannot recognize snares. In deduction, the prince must be cunning and courageous.   For Machiavelli, the wellbeing of the state has no ethical or moral implications. Anything that benefits the state is considered superior.   Machiavelli considers the appearance of being religious as the most powerful quality.

Economics: Keynes vs. Hayek Essay -- Keynes vs. Hayek, 2014

The past few years the United States has seen some rough economic times.   The unemployment rate is extremely high and many people have lost their homes and businesses.   Because there are so many factors in an economy, it is hard to find the right people to blame.   The protest group â€Å"Occupy Wall Street† has come to the conclusion that corporations are making us poor through taking advantage of us and the governmental system.  Ã‚   The share of income going to the top one percent of Americans has increased dramatically over the past few years and â€Å"Occupy Wall Street† is outraged.   They are calling for increased governmental regulation so that the lower quintile Americans can gain some equality (Cesca).     I wonder who is actually at fault.   Is it actually this top one percent who have been hurting us or some other factor?   Maybe the government has created the problem. A good way to approach it is to take a step back and look at the philosophy of economics.   From learning about classical economic theory, modern dilemmas, specifically â€Å"Occupy Wall Street,† may be easier to solve.   There are two main theories on economics and how a society should run.   The classical theory is that of the British economist, John Maynard Keynes.  Ã‚   The other, less popular theory is from the Austrian economist, Friedrich August Hayek.   These two highly respected economists did most of their important work in the mid-20th  century. (Cochran and Glahe 69).

Employee Motivational Theories and Concepts Essay

Numerous theories on the subject of employee motivation have been developed and published for the better part of this century. While early employers thought of their workers as just another input into the production of goods and services (Lindner, 1998), employees were becoming increasingly dissatisfied with working conditions and malevolent management. As post-war, labor tensions mounted in the 1920s, employers needed to change their approach to employee relations if they were to avoid costly, and sometimes violent, labor strikes. Early motivational theories set the foundation for the development of 20th century concepts, including the move to get â€Å"Googled† and motivational techniques based on business strengths found in the corporate toolbox. Early Motivational Theories George Elton Mayo, an Australian-born psychologist and Harvard Professor, began significant research in 1927 in an attempt to demonstrate that employees, if appropriately motivated, are more productive and can achieve greater return through appropriate human relationship management techniques (Trahair & Zaleznik, 2005). This research, referred to as the â€Å"Hawthorne Studies,† found that employees are not only motivated by financial gain, but also by the behavior and attitude of their supervisors. During these studies, the employees responded positively to the mere fact that they were receiving attention from their supervisor as a result of the experiment. In his article, Gordon Marshall (1998) noted that â€Å"the term ‘Hawthorne effect’ is now widely used to refer to the behavior-modifying effects of being the subject of social investigation, regardless of the context of the investigation. More generally, the researchers concluded that supervisory style greatly affected worker productivity† (para. 1) and that â€Å"enhanced productivity therefore depends on management sensitivity to, and manipulation of, the ‘human relations’ of production† (para. 2). This represented a dramatic paradigm shift for employers and theorists alike. Subsequent to the conclusion of the infamous Hawthorne Studies, five primary motivational theories have developed that have increased the understanding of what truly motivates employees. They are Maslow’s need-hierarchy, Hertzberg’s two-factor system, Vroom’s expectancy theory, Adam’s equity theory, and Skinner’s reinforcement theory. Maslow identified that employees, in general, have five primary levels of needs that include psychological (e.g. air, food, shelter), safety (e.g. security, order, stability), belongingness (e.g. love, family, relationships), esteem (e.g. achievement, status, responsibility), and self-actualization (McLeod, 2007). Maslow further noted that, in order to provide motivation, the lower levels would need to be satisfied before one progressed to the higher levels. Hertzberg classified motivation into two, distinct factors. He believed that intrinsic factors (or motivators) produce job satisfaction through achievement and recognition while extrinsic (or hygiene) factors produce dissatisfaction. He identified extrinsic factors to be associated with compensation and perceived job security, or lack thereof. Vroom theorized that demonstrated effort would lead to performance which, in turn, would lead to reward (either positive or negative). The more positive the reward the more highly motivated the employee would be. To the contrary, negative rewards would result in a lesser motivated employee. Adams found that employees want to ensure that there is a sense of fairness and equity between themselves and their co-workers. He believed that equity is achieved when employees are contributing, in terms of input and output, at the same rate. Skinner’s theory was likely the most simplistic, He established that employees will repeat behaviors that lead to positive outcomes and eliminate or minimize behaviors that lead to negative outcomes. He conceived that, if managers positively reinforce desired behavior, it would lead to positive outcomes and that managers should negatively reinforce employee behavior that leads to negative outcomes (Lindner, 1998). James R. Lindner, Professor of Management and Research at Ohio State University, has conducted extensive research on this topic. In his paper â€Å"Understanding Employee Motivation,† he further extrapolated on the five theories, providing a comparative analysis, and offering a summary definition that focuses on the psychological process and â€Å"inner force† associated with the accomplishment of personal and organizational goals (Lindner, 1998). 20th Century Concepts In addition to studying popular theories associated with employee motivation, Lindner (1998) includes the methodology and outcomes of an independent study, conducted at Ohio State University, that sought to rank the importance of ten motivating factors. The results of this study were compelling; with â€Å"interesting work† ranking as number one over other more commonly identified motivators, such as wages and job security. In comparing these results with Maslow’s hierarchy of needs, among others, he found that the results are mixed, with the highest ranked factor (interesting work) being one of self-actualization and contrary to Maslow’s findings (Lindner, 1998). This presents a divergent result that challenges Maslow’s assumption that the lower needs must be satisfied before a person can achieve their potential and self-actualize (McLeod, 2007, para.16). This does not negate Maslow’s work, but rather demonstrates that a natural evolution may have taken place with the modern workforce due to the progression of motivation strategies. This is a credit to the work of early theorists, and a call to arms for those that continue this research. Get Googled But history has yet to definitively answer the question, â€Å"what is the best method(s) to motivate employees?† The imprecise answer continues to be: it depends. Many successful organizations incorporate a variety of programs aimed at motivating their employees, based on their specific population. Google Inc., for example, is leading the way to restructure management so that employees can streamline creative ideas that produce blockbuster new products. They are rewarding employees with perks like onsite swimming pools, allowing employees to bring their pets to work, providing onsite child care, and all the free food employees want (â€Å"How Google Inc. Rewards Its Employees,† 2010, Thinking Leaders, para.1). While this may not be realistic for every organization, there is something to be said about the fact that Google, Inc. is consistently ranked by Fortune magazine as the best place in the U.S. to work. However there are things that a company can do to motivate their employees that are low or no cost and likely already exist in their corporate toolbox. The Corporate Toolbox Most successful organizations pride themselves on their ability to promote their product or service to achieve the desired level of profitability. They develop strategic plans, set production goals and persuade their customers that they are best of the best in their field. They are advertisers and peddlers of wares. So what does this have to do with motivation? Robert Hershey, Director of James E. Rogers College of Law at the University of Arizona and contributing author to the Journal of Managerial Psychology, contends that there is a significant correlation between an organization’s ability to successfully promote their business and thrive at motivating their employees. He notes that â€Å"we do not need one more theory of motivation; we need better insight into the psychology of advertising. We can take some tried-and-true product advertising techniques that have been found to be effective and use them in a human resources and management context. But before we do that, the point must be made that, as a practical matter, our vocabulary and attention require a shift from the motivation jargon of needs, expectancy, two-factor theories, etc., to an emphasis on communications practices, because persuasion requires the transmission of information† (Hershey, 1993). If Hershey is correct, then an emphasis on communication and inclusion would create an environment ripe for employee motivation. One could also argue that, if communication is key, allowing input and empowered decision making is the next logical step to producing a motivated employee. Carolyn Wiley, Professor of Business at Roosevelt University, concurs with this notion and provides the following supporting statements in her article â€Å"Creating an Environment for Employee Motivation†: When employees have an opportunity to provide input, this increases their survival rate and their sense of commitment. In many very small companies, a natural sense of owners hip often develops among the employees. However, as companies grow, feelings of ownership and commitment start to decline. To increase commitment as the organization grows, managers must change how they define who retains control. Shared decision making is essential both to company success and employee survival. Workers generally do not resist their own ideas and decisions. Rather, they are motivated to fulfill them. (Wiley, 1992, para.14) While this may seem threatening to traditional leaders, it should not be viewed as surrendering control. Employees that are empowered through inclusion are ambassadors for organizational success. It is only through mutual success that both the employee and company thrive. It seems so simple, but eludes even the most progressive of companies. Most organizations are more inclined to spend thousands of dollars creating recognition programs, building home office environments, developing bonus structures and hosting employee appreciation events rather than recognizing that most employees are merely looking to be valued. The same attention that motivated the Hawthorne workers applies to the modern employee who just wants to contribute and receive credit for their effort. Conclusion There is certainly compelling evidence to indicate that employee motivation comes in many forms. Whether one places their belief in the theoretical assumptions of a Maslow or Hertzberg, their financial backing in the creation of a Google-esque environment, or capitalize on their organizational strengths to communicate and persuade, there is clear agreement that the ability to successfully motivate employees is essential for corporate success and sustainability. The concept of positive human relation management has finally taken its place at the forefront of organizational strategies and, with it, the evolution of employee motivation.

Lamb to the Slaughter Essay

Lamb to the Slaughter by Roald Dahl uses the literary devices of dramatic irony, foreshadowing, and imagery to depict a dark comedy by grasping the idea of a tragedy becoming humorous. There are multiple uses and examples of irony throughout this short story that relate to the idea of a dark comedy. One key quote of dramatic irony comes from the end of the book stating, Personally, I think its right here on the premises.? Probably right under our very noses. What do you think, Jack This quote here shows us as that the detectives have no idea that they are actually eating the evidence of the murder right then and there. We, as the audience, obviously know what is going on and by Mary Maloney chuckling at that statement shows us that Dahl turned something as horrible as murder into something that she laughs at in the end referring to the idea of dark comedy. Verbal irony is also represented in this piece of literature. When she goes to the market, she talks to the grocer and states, ? No, Ive got meat, thanks. I got a nice leg of lam, from the freezer.? (pg. 20) This is verbal irony because it shows that what she is saying is basically telling the grocer what she used for the murder of her husband. The irony here is amusing, knowing the fact that killed the supposed love of her life and can so easily lie about it. So again, the verbal irony really catches the tone of the dark comedy that Dahl is trying to capture here. Both dramatic and verbal irony relate to eac h other in the sense that the audience feels the ideas of a tragedy as something funny therefore, relating back to the overall picture of the piece of literate as a dark comedy in the short story
