In the leading city of Athens 2,500 years ago during the Golden Age, a peculiar philosopher was born into the reign of Pericles. Socrates went against common religion, influenced social roles and people, and was the founder of the Socratic Method. Religious opinions affected Socrates’ life a great deal. Whereas most Athenians observed polytheism and†¦show more content†¦They were very popular but loathed at the same time because of the financial problems they were causing. For example, the most famous sophist was called Corax. He had a student called Tisias who refused to pay the fee for his classes, he said â€Å"Before I started, you promised you would teach me to persuade anyone to do whatever I wanted. Let me now persuade you not to ask for your fee. If you still demand it, you did not do what you promised, therefore I owe you nothing.† However, Socrates discredited this, â€Å"However, not one of these things is true; nor, if you have heard from anyone t hat I attempt to teach men and require payment, is this true.† (Plato, n.d.). Socrates irritated people by insisting things that could not be true. Critobulus, who was considered by many to be the most handsome man in Athens. However, Socrates, with his protruding eyes and large nose insisted he was more stunning than Critobulus. Socrates defended this by saying things such as â€Å"Because while yours see straight ahead, mine, by bulging out as they do, see also to the sides,† and â€Å"Mine, I consider, granting that Providence made us noses to smell with. For your nostrils look down toward the ground, but mine are wide open and turned outward so that I can catch scents from all around.† (Zannos, 2004). Another story of Socrates impacting the life of an individual is shown by the dialogue that he had with a young man he met at a wrestling school named Lysis.

Effectiveness Of The Leadership Role And Performance Of...

The purpose of this report is to critically analyse the effectiveness of the leadership role and performance of John F Kennedy (from this point forward, known as JFK). To review JFK’s leadership style and his behaviour during the Cuban Missile Crisis in 1962. Let us first look at a definition of leadership. According to Kruse (2013) â€Å"Leadership is a process of social influence, which maximises the efforts of others, towards the achievement of a goal†. In today’s world, leadership is all the more important as there is an ever changing environment with in the business world, and to gain the most out of this changing environment, a leader needs to be flexible and quick witted to ensure that they are maximising the potential of a situation. For this report, we have used the framework developed by Robbins (1997 as cited by DuBrin 2013) which analyses the effectiveness of leadership by looking at the Leader Characteristics, Leader Behaviour and Style, Group Member Characteristics, Internal and External Environment which all lead to Leadership Effectiveness. JFK was the 35th President of the United States of America (from this point on to be USA). He was in office from January 1931 until he was assassinated in November 1963. JFK was both the youngest President of the USA to be elected into office and the youngest President of the USA to die (Friedel Sidey).

It isn’t until he is out of Europe traveling with his servant†¦show more content†¦Eldorado’s jewels create ambitious greed in Candide, overshadowing his main concern of surviving for his Cunegonde. Candide truly believes in the philosophy that indeed everything is for the best and Eldo rado is the ideal place for this notion to flourish but he leaves this â€Å"beautiful dream† out of spite because he cannot function in a society that cannot be bought (Silver 2). The very true world he despises is actually the only place he has succeeded. After leaving Eldorado with numerous sheep packed with goods and â€Å"fifty loaded with gold, jewels, and diamonds† they are only left with two after a hundred days march that strained the convoy to its limits of starvation (Voltaire 39). They reach a Dutch town where they learn that Miss Cunegonde is a mistress to the governor in Buenos Aires and set out to find a merchant ship to set sail. The Spanish merchant Candide and Cacambo hire to transport them tells them they must not return for fear of being hanged and instead sends Cacambo with several millions to purchase her away. The men were to rendezvous in Italy once Candide secured a second vessel to take him. He finally procures a Dutch ship captained by a Mr. Vanderdendur who offers to take Candide to Italy for â€Å"ten thousand piasters†, notices the ease at which he agrees and soon increases the fee to twenty then â€Å"thirty thousand piasters† (Voltaire 41).

Determination of Iron in Natural Water by Spectrophotometry Essay Sample free essay sample

Purpose: To find the Fe in natural H2O by spectrophotometry. Abstraction: The Fe in natural H2O was determined by using spectrophotometric analysis. That was done by mensurating the optical density of five Fe ( oPH ) 2+3 criterions at 510 nanometers. From that information. a standardization curve was plotted and used to happen the sum of Fe2+ that was in two unknown H2O samples based on the optical density readings obtained with them at 510nm. The equation of the line was found to be y=0. 1765x + 0. 0705. It was so determined that there was no Fe nowadays in H2O sample A. while for H2O sample B. the Fe was present in the proportions of 0. 9037ppm. 1. 614?10-5M and 9. 037?10-3 % . Introduction: Spectroscopy is the survey of the interaction of visible radiation or electromagnetic radiation with affair. Spectrophotometry is any technique that uses visible radiation to mensurate chemical concentrations. Electromagnetic radiation is a signifier of energy when reacted with affair. can be absorbed. reflected or refracted. and how EMR reacts with affair depends on the belongingss of the stuff. based on the frequence. wavelength. optical density etc. The electromagnetic spectrum shows representative molecular procedures that occur when visible radiation in each part is absorbed. The seeable spectrum spans the wavelength scope 380-780nm. so each part is absorbs at different wavelengths. The red-orange composite that forms between Iron ( II ) and 1. 10-phenanthroline is utile for the finding of Fe in H2O supplies. The reagent is a weak base that reacts to organize phenanthrolinium ion in acidic media. The red-orange composite that forms between Fe ( II ) and 1. 10-phenanthroline ( orthophenanthroline ) is utile in finding Fe in H2O supplies. The reagent is a weak base that reacts to organize phenanthrolinium ion. phenH+ . in acidic media. A normally used method for the finding of hint sums of Fe involves the complexation of Fe2+ with 1. 10-phenanthroline ( phen ) to bring forth an intensely ruddy orange colored complex: Fe2+ + 3phen Fe ( phen ) 32+ . Since the Fe nowadays in the H2O preponderantly exists as Fe3+ . it is necessary t o first cut down Fe3+ to Fe2+ . This is accomplished by the add-on of the cut downing agent hydroxylamine. An surplus of cut downing agent is needed to keep Fe in the +2 province ( because dissolved O will reoxidize Fe2+ to Fe3+ ) . Fe2+ is quantitatively complexed by 1. 10-phenanthroline in the pH scope from 3 to 9. Sodium ethanoate is used as a buffer to keep a changeless pH at 3. 5. If the pH is excessively high. the Fe2+ will be oxidized to Fe3+ ; if the pH is excessively low. H+ will vie with Fe2+ for the basic 1. 10-phenanthroline ( to organize phenH+ ) . Either manner. complete complexation won’t be achieved. The finding of the iron-phen composite is performed with a spectrophotometer at a fixed wavelength of 510nm utilizing external standardization based on Fe standard solutions. In the spectrophotometer. visible radiation is passed through a monochromator ( a prism. a grate. or even a filter ) to choose a scope of wavelength and some of the visible radiation may be absorbed by the sample hence givin g the transmission. which is the fraction of the original visible radiation that passes through the sample and has the scope 0 to 1. Optical density. sometimes called optical denseness. is the bosom of spectrophotometry as applied to analytical chemical science Beer-Lambert’s jurisprudence. A=ebc. where the concentration of the sample. M. way length. centimeter. measure ( epsilon ) is called the molar absorption factor. Molar absorption factor is the feature of a substance that tells how much visible radiation is absorbed at a peculiar wavelength. Both a and e depend on the wavelength of electromagnetic radiation. Attenuation of radiation as it passes through the sample leads to a transmission of less than 1. Besides soaking up by the analyte. several extra phenomena contribute to the net fading of radiation. including contemplation and soaking up by the sample container. soaking up by constituents of the sample matrix other than the analyte. and the sprinkling of radiation. To counterbalance for this loss of the electromagnetic radiation’s power. we use a method space. Method: Standard Fe solutions. Na acetate solution. 10 % hydroxylamine hydrochloride. 1-10 phenanthroline and solvent clean solutions were prepared earlier manus to utilize throughout the experiment. 2. 00. 4. 00. 6. 00. 8. 00 and 10. 00 milliliter of Fe stock solution were pipetted into five 100mL volumetric flasks. To each flask. 1mL of 10 % hydroxylamine hydrocholride. 10 milliliter of Na ethanoate and 10mL of 1. 10-phenanthroline solution was added. The mixture was allowed to stand for 10 proceedingss so made up to the grade with distilled H2O. The optical density of all five criterions solutions were determined with regard to the space at 510 nanometer. 10. 0mL of H2O sample was transferred to a 100mL volumetric flask. and treated precisely the same manner as the criterions. mensurating the optical density with regard to the space. Consequences: Concentration of Fe ( oPH ) 2+| Optical density at 510nm|1| 0. 251|2| 0. 424|3| 0. 587|4| 0. 785|5| 0. 482|Unknown| Absorbance at 510nm|A| -0. 07|B| 0. 023| Table 1 demoing the optical density obtained at a wavelength of 510nm. utilizing a OHAUS spectrophotometer. for concentrations of Fe ( oPH ) 2+ of ( 1. 2. 3. 4. 5 ) ppms and two unknown H2O samples A and B. Calculations: ( I ) Equation of the line: y=0. 1765x + 0. 0705. Sample A optical density -0. 007. hence. that value does non hold to be substituted in the equation as it is a known fact that a negative optical density reading agencies there is no Fe analyte present. ( two ) Since a ( 1/10 ) dilution was undertaken. the optical density reading for sample B could besides be expressed as ( 0. 023 ten 10 ) = 0. 23. Substituted in the above equation we get: 0. 23= 0. 1765x + 0. 07050. 23- 0. 0705= 0. 1765x0. 1595=0. 1765xx=0. 1765/0. 1595= 0. 9037ppm. or 0. 9037mg/L ( III ) Ar of Fe = 56g/molmoles of Fe2+= mass/molar mass= 0. 9037 ten 10-3g/56g/mol= 1. 614?10-5M Fe2+ ( four ) denseness of water= 1g/mL or 1g/cm3mass of water= denseness x volume= 1 ten 10= 10g ( V ) % Fe2+ in H2O sample B= = 0. 9037 ten 10-3g Fe2+ x 100/ 10g water= 9. 037 ten 10-3 % Fe2+ Discussion: The concentration of criterion A was 1 ppm and its optical density measured at 510 nanometer was 0251. The concentration of standard B was 2 ppm and its optical density measured at 510nm was 0. 424. The concentration of standard C was 3 ppm and its optical density measured at 510nm was 0. 587. The concentration of standard D was 4 ppm and its optical density measured at 510nm was 0. 785. While the concentration of standard E was 5 ppm and its optical density measured at 510nm was 0. 482. The tendency observed with the concentration of the first four Fe ( oPH ) 32+ criterions and the optical density readings obtained with them was that as the concentration increased. so excessively did the optical density readings measured. That meant that concentration was straight relative to absorbance ( A? C ) . Hence. Beer-Lambert’s jurisprudence was observed. The concentration values every bit good as the optical density readings at 510nm for the Fe ( oPH ) 32+ criterions were so used to plot a graph of optical density versus concentration. with the dependant on the x- axis. The graph plotted yielded a consecutive line and the equation of the line was found to be y=0. 1765x + 0. 0705. It is of import to observe at this point that 510 nanometer was the used wavelength because it represented ?max for the Fe ( oPH ) 32+ complex. In other words. it is the wavelength at which the composite absorbs best and hence the extremum of its optical density spectrum would be located at that wavelength. Subsequently the equation of the line mentioned above was utilized by utilizing the optical density readings for H2O samples A and B. which were -0. 007 and 0. 023 severally. Since the optical density readings obtained for sample A was negative. that meant that there was no Fe nowadays for sample A. While for sample B. the value was positive and since A ( 1/10 ) dilution was used computations was done. utilizing and absorbance value of ( 0. 023 * 10= 0. 23 ) . It followed that the Fe was present in H2O sample B in the proportions of 0. 9037ppm. 1. 614?10-5M and 9. 037?10-3 % . Hence. Fe was present in hint sums in sample C. This experiment was non short of mistakes though. as there was one questionable consequences that was encountered in this experiment. For the optical density readings obtained for the 5 ppm criterions was 0. 482. which was contradictory to Beer’s jurisprudence. That may hold been as a consequence of the formation of Fe salts such as phosphates. As the acid buffer may hold failed to maintain the pH at the optimum of 3. 5. It may hold been besides as a consequence of utilizing incorrect proportion of reagents by experimenters when doing up that criterion. Hence. when carry oning this experiment. suited reagents must be used in order to keep optimal reaction vas conditions. The experimenters must besides guarantee that he/she follows all the instructions given with respects to doing up criterion to forestall unwante d consequences. Decision: Spectrophotometric analysis was successfully utilised to bring forth a standardization curve for Fe ( oPH ) 32+ criterions. The equation of the line was found to be y=0. 1765x + 0. 0705. In add-on. that equation was manipulated to find the sum of Fe2+ in the two H2O samples.

Priestleys perspective Essay Example For Students

Priestleys perspective Essay Mr Birling is partly responsible for Eva Smiths suicide he discharged her from his factory for suddenly wanting more money, he was responsible for her being out of work for two months, being forced into lodgings and being half-starved. Overall he is not totally responsible for the suicide itself. Birlings son, Eric, causes this. He paid Eva for sexual intercourse when she became a prostitute and she fell pregnant with his lovechild. Birling is wounded and disappointed when he finds this out, you damned fool why didnt you come to me when you found yourself in this mess? Erics reply to this was that his father was not the kind of person you come to. This shows that Birling was never close to his son. He accepts absolutely no responsibility still, unlike Sheila who accepts all responsibility. J. B. Priestley uses dramatic devices and dramatic irony in the play. His main device was the photograph and his main ironic character is Mr Birling. When Inspector Goole reveals he has a photograph, this creates tension and shows the characters reactions to the photograph, an example of this is Sheila, when she sees the photograph she starts to cry and she flees from the room and when she returns she is anxious to admit her wrong-doings. Also she decides she cannot marry Gerald after he was involved with Daisy Renton. Mr Birling represents a very unattractive and selfish kind of man. He is obsessed by money. Even at the end of the play he feels sorry for what has happened but he still thinks in terms of money. He says to the Inspector look, Inspector Id give thousands. Although everything has been revealed about his family, he still tries to disguise this. When the possibility of the Inspector being a deceiver, he happily believes that it never happened and that if the Inspector was fake, so must the things that emerged. He impersonates the Inspector . This is example of pride before the phone rings. His pride makes you think that it was all a hoax but when the telephone rings it makes you wonder.  Mr Birling represents Priestleys hate of businessmen whose only care is making a profit. He will never learn from his mistakes. Sheila is aware of the mystery surrounding the Inspector, yet realises that there is no point in trying to hide the facts from him. She is stable about the breaking up of her engagement and remains cool, calm and collected. She will not be hurried into accepting the wedding ring back once the Inspector had left, she is unable to accept her parents attitude and behaviour towards the Inspector and she is both amazed and concerned that they havent learned anything from the occurrence. Although the Inspector might be a hoax, the family have still behaved in an entirely unsuitable manner, she feels. She also learns of her responsibilities to others less fortunate than herself and the importance of the community. She is sensitive towards everything. Her readiness to learn from experience is in great contrast to her parents. This play was relevant to the audience at that time; it was like of their past. Priestly feels guilty about the lower classes so he tries to demolish stereotypes, i.e. Eva being a normal unemployed girl of her time. Inspector Goole is Priestleys perspective.  The message the play is trying to convey is that we should take responsibility for our actions and consider the consequences the might have for other members of society. Priestley is also trying to say that you shouldnt keep things secret because you conscience will unravel them.
