Fractional Distillation Process To Separate Organic Liquids

Fractional Distillation Process To Separate Organic Liquids Distillation is a very useful method of purifiying liquids. Simple distillation is used when a pure solvent is required to be obtained from the solution. This is usually water. On the other hand, fractional distilation is basically used for the separation of a mixture of two miscible organic liquids having different boiling points. A common example of two liquids that mix with each other are ethanol and water. Another example is petrol and paraffin. In this experiment, a mixture of acetone and toluene was provided. Basically, the liquid mixture was boiled to evaporate the liquid that had the lowest boiling point, referred to as the first fraction. The vapour passed up through a fractionating column, which is not used in a simple distillation. As the mixture vaopur passed up the fractionating column, it continually condensed and evaporated. This caused it to become increasingly richer in the liquid with the lowest boiling point until the vapour that reached the top consisted almost entirely of the component with the lowest boiling point. The vapour is then cooled in the condenser and so it condensed back to a liquid, which was collected, hence referred to as the distillate. When almost all the liquid with the lowest boiling point was distilled over, the temperature rised rapidly showing that a mixture of both liquids was distilling over. This should be collected in a separate container and discarded. Once the temperature reached the boiling point of the second liquid, the liquid was then distilled into another container. This basically explained the process of fractional distillation. However, there is a theory behind all this, because the process of distillation should be related in reference to an ideal liquid mixture where one is more volatile than the other. Regarding the mixture of acetone/toluene provided in this experiment, ideal behaviour was assumed and once the process was carried out, the more volatile liquid was found by finding the boiling point of each component. It was noted that the more volatile liquid was acetone since this had a lower boiling point. This was discussed further in relation to boiling point-composition graphs. 2. Method 2.1 Chemicals used Reagent: Grade: Manufacturer: Acetone GPR BDH Toluene GPR Merck 2,4-dinitrophenylhydrazine GPR Riedel de Haem Sodium hydroxide GPR Tinstar Iodine GPR BDH Dioxane GPR Aldrich A mixture of acteone (BDH, GPR) and toluene (Merck, GPR). 2.2 Apparatus Fractionating column, thermometer, 100 mL round bottomed flask as the distillation pot, glass beads, anti-bumping granules, cotton wool, tight clip, Leibig condenser with rubber tubings, heating mantle, connecting side-arms as part of the fractional distillation setup, retort stand with clamp, water supply, 10 mL and 100 mL measuring cylinders, electronic balance, test-tubes, distilled water. 2.3 Procedure Part a) The separation of the acetone/toluene mixture and the measurement of the boiling points of each. The apparatus for fractional distillation was set-up appropriately using a 100 mL round-bottomed flask, the fractionating column provided, insulated well with cotton wool. 50 mL of the acetone/toluene mixture was placed in the 100 mL round-bottomed flask. This was measured using a measuring cylinder. A few boiling chips or anti-bumping granules, which were small irregularly pieces of material, were added to the round-bottomed flask in order to allow prolonged boiling. The apparatus was clamped accordingly from the neck of the round-bottomed flask and checked to be balanced and well set-up before the heating mantle was switched on. Then round-bottomed flask was heated slowly using a heating mantle, until the reading on the thermometer reached a steady state and drops were observed to condense out of the Leibig condenser. This was the boiling point of the first fraction. This steady state temperature was recorded and the distillate was collected in a 100 mL measuring cylinder. The distillation was allowed to proceed until no more liquid got out of the condenser into the measuring cylinder. Then the volume of the first fraction was recorded. When all of the first fraction was distilled out, the temperature at the top of the column was observed to increase and then reached a second steady state, which was the boiling point of the second fraction. Drops of the second fraction were observed to start to condense out of the Leibig condenser. This steady state temperature which was the boiling point of the second fraction, was recorded. The second distillate was collected in a clean measuring cylinder and then its volume was recorded. Part b) The usage of two different tests for the identification of the liquid distillate having a carbonyl group. (acetone) 2,4-DNPH test was first carried out. 2-3 drops of the liquid to be tested were added to 3 mL of 2,4-dinitrophenylhydrazine, and shaken. Any observations and inferences were recorded. The iodofrom test was then carried out. 4 micro drops of the liquid to be tested were dissolved in 2 mL distilled water, in a test-tube. The drops were added carefully using a pipette. 2 mL of 10 % sodium hydroxide were then added together with 2 mL of iodine solution, which were added slowly by drops. The substance was insoluble in water and therefore 2 mL dioxane were added. This was done so that the substance dissolved. Any observations and inferences were then recorded. Each test was carried out twice, for each distillate. Diagram: The set-up apparatus for Fractional Distillation. Precautions It was ensured that the thermometre was positioned accordingly at the mouth opening of the Leibig condenser, where it indicated which fraction was being evaporated by noting the temperature readings. The thermometer position was very important because if the thermometer bulb was to be placed too high, the vapours would reach it before they pass into the side-arm to be collected, and the observed boiling point would be lower than it should be. If the thermometer bulb was to be placed too low, vapours of impurities might reach it, and a high reading for the boiling point range would be given. It was ensured that the fractionating column was filled and packed with glass beads, for maximum possible surface area for vapour to condense on. It was ensured that a joint clip was used and attached between the end of the condenser and the side arm so that there was complete attachment of the setup together and any spillage of the liquid distillate was prevented, but allowed to drop only from the side arm tube, where the vent was present. It was ensured that the Leibig condenser provided was set-up accordingly with opening below meant for water to be pumped in while the opening at the top meant for water to be pumped out, and vice-versa. Although water pressure transfers from a higher to a lower height, if the condenser had to be the other way round the liquid might not be cooled completely as it would only condense the top portion of the condenser. Therefore if the rest of the part of the Leibig condenser was not cooled, the liquid would might evaporate into gas again at the bottom part of the condenser. This explained the importance of correct set-up. It was ensured that as much of the second fraction as possible was collected, however at the same time care was taken so as not to allow the distillation pot, i.e. the 100 mL round-bottomed flask, to boil dry otherwise the residues might ignite or expode. It was ensured that anti-bumping granules were used. These were placed in the 100 mL round-bottomed flask with the 50 mL of the acetone/toluene mixture. The granules were important since they allowed prolonged, smoother boiling without bumping and continuous even formation and release of vapour bubbles were observed. It was ensured that cotton wool was used so that the whole fractionating column was completely wrapped and covered for insulation or lagging. This was important so that the apparatus remained as warm as possible and excessive cooling was avoided, but occurred very slowly. It was ensured that parallax errors were avoided as much as possible by looking normally to the scale of the measuring cylinder were when taking readings of the volumes of liquids, or when taking temperature readings from the thermometre. For safety measures, it was ensured that care was taken when distilling organic solvents in order to avoid explosions and fires. Hence, it was ensured that the vapour did not come into contact with flames, sources of sparks or very hot surfaces such as hot plates. It was ensured that the apparatus was not completely sealed. A vent in the system was required so as to prevent pressure build up in the system as heating was carried out. Otherwise the apparatus would simply blow apart. Therefore, for safey measures, it was ensured that heating in a closed system was avoided. 3. Results Volume of acetone and toluene mixture used was: 50.0 mL Observations Inferences from the 2,4-DNPH test A red-orange precipitate was formed. This positive result means that a carbonyl group, was present in the formula of the substance. No precipitate was formed. The substance contained no carbonyl group, in its formula, hence a negative result was obtained. Observations Inferences from the Iodoform test A pale yellow precipitate was formed. This means that the substance contains a in its formula, hence it gave a positive iodoform with an antiseptic smell. No precipitate was formed. No group was present in the formula of the substance, hence a negative result was obtained. Suspected Identity of Fraction 4. Discussion: At any given temperature a pure liquid in a close container will establish an equilibrium with its vapour: liquidvapour The equilibrium vapour pressure above the liquid will depend upon the temperature. Considering mixing two liquids in different proportions, Raoults Law states that for an ideal mixture at a fixed temperature, the vapour pressure of each component is proportional to its mole fraction. This means that the graph of the vapour pressure of each component against its mole fraction will be a straight line passing through the origin. Considering the case of two volatile liquids, as in this experiment, each of which contributes to the total vapour pressure, by Daltons Law of partial pressures it is known that the total vapour pressure of the mixture is the sum of that of the components and this will also give a straight line when plotted against molar composition. Therefore it could be said that it is more convenient to plot boiling point of the mixture against molar composition. The boiling point of a liquid is the temperature as which its vapour pressure reaches the external atmospheric pressure. Since the less volatile component will have the highest boiling point, being toluene in this case, the vapour pressure curves in figure 1 lead to boiling point-composition graph as shown in figure 2. Two curves were drawn in this diagram since the liquid mixture and the vapour in equilibrium with it do not have the same composition. The vapour will always contain a higher proportion of the more volatile (lower boiling point) component. This difference in composition between the liquid and vapour phases in equilibrium enables such a liiquid mixture to be separated by disitllation. To separate a liquid mixture which obeys Raoults Law, one must repeatedly distill, i.e. boil the liquid and condense the vapour. This is fractional distillation, and rather than carrying out each stage separately, it is convenient to use a fractionating column designed to allow many such steps to occur simultaneously. Fractional distillation is widely used in industrial chemistry for separating mixtures of miscible liquids which boil at different temperatures. For example pure oxygen, nitrogen and noble gases may be obtained from liquid air by fractional distillation. Another example is the hydrocarbons in crude oil which can be separated into useful fractions. In order to discuss the results obtained, one should say that these were clearly explained in the table of results tabulated. It was observed that the boiling points measured were very reliable since these were checked using the organic compounds database website, maintanied by Colby College and the components of the mixture provided i.e acetone and toluene were listed. One should say that there were many readings, as can be observed from the table of results, where the temperature remained constant as more drops of distillate were collected.This confirmed the boiling point of the organic liquid. Some modifications could be made for the procedure of the fractional distillation process. For instance, rather than using a fractionating column packed with glass beads to give the maximum possible surface area for vapour to condense on, a fractionating column with spikes of glass sticking out from the sides could be used, and this would serve the same purpose. Sources of error Once the temperature on the thermometre was observed to rise rapidly, this meant that a mixture of both organic liquids were distilling over. Hence, these few drops should have been collected in a separate container and discarded since they did not consist of an individual liquid. However, this was not done. Hence the volume of the first fraction (acetone) collected was slightly greater than it was supposed to be and was not of the pure organic liquid but had some drops of the second fraction (toluene) in it. this is the container was replaced once the temperature was raised. The thermometer was repeatedly being moved up and down when the temperature readings were taken. This is because some of the scale was hidden by the set-up itself. This movement of the thermometre might affected the results slightly because the boiling temperature range obtained might varied a bit due to this action. 5. Conclusion: It was concluded that fractional distillation was carried out and therefore separation of two organic liquids acetone/toluene mixture occurred. It was also concluded that the boiling point of each component was found and tests on each liquid component, once distillated and separated, were carried out in order to prove the identity of the component.

What is sexting? Essay

In this age of technology and information, internet and mobile technology devices dominate our society (Burton, L, 2012, p.1), with over 90% of Australians aged 15-17 owning mobile phones (Australian Communications and Media Authority, 2010, â‚ ±4). Today’s teens are also overexposed to sexual content in many aspects of the media (Burton, L, 2012). This highly sexualised digital culture has transformed the way youth relate to one other (Walker. S., Sanci, L. & Temple-Smith, M, 2011). One phenomenon that has emerged from the increased accessibility of these devices and sexual exposure is the practice of ‘sexting’ (Society Pages, 2013, â‚ ±1). The term ‘sexting’ derives from merging the words ‘texting’ and ‘sex’ and â€Å"refers to the sending of sexually provocative material from modern communications devices† (Forde, L. & Hardley, S., 2011). ‘Sexting’ is currently receiving mass media attention (Walker, S., Sanci, L., & Temple-Smith, M., 2011). It is recognised as one of latest youth phenomena in popular culture (Funnell, N, 2012). Although the sharing of sexually explicit material is not a new concept, it has become simpler with the internet (Walker, S., Sanci, L., & Temple-Smith, M., 2011). Shared images â€Å"become part of a young person’s digital footprint, which may last forever and have the potential to damage future career prospects or relationships† (NSW Government, 2008, â‚ ±3.). The prevalence of sexting A national survey conducted in 2010 by the organisation Understanding Teenagers found that 59% of teenagers have electronically transmitted sexually suggestive material (Understanding Teenagers, 2010, â‚ ±3). In another survey conducted by the popular teen girl magazine Girlfriend found that 40% of 558 participants had been involved in sexting (Parliament of Victoria Law Reform Committee Sexting Inquiry (PVLRCSI), 2012). In Queensland alone, 459 sexting offences were reported in 2011 (PVLRCSI, 2012) and in Western Australia sexting offences have tripled in number from 2009 to 2011 (PVLRCSI, 2012). Research by American psychologist Andrew Smiler found various causes that attribute to sexting: to demonstrate commitment in a relationship, to impress friends, to harass or bully, or as a dare. According to an article in the Teacher Learning Network journal, In popular culture, sexting is seen as a young person’s phenomenon: mobile phones, raunch culture, a lack of inhibition, a lack of respect even a lack of morals are seen by many as the perfect storm that has created the sexting phenomenon.(Funnell, N, 2012). Looking at sexting through the lens of Sociological Theory Feminist Theory Sexting is recognised as a gender related issue because young girls feel pressure from the over-sexualised media to present themselves as sexually desirable. Similarly, young men have been conditioned to expect this behaviour. Sexting has created a mechanism for young people to actualize these expectations (Walker. S., Sanci, L. & Temple-Smith, M, 2011). It is understood that young girls are at greater risk of adverse effects than young men by this behaviour (Walker. S., Sanci, L. & Temple-Smith, M, 2011). Experts go as far as to claim â€Å"†¦the possibility of a link between sexting and gendered sexual violence targeting women† (Walker. S., Sanci, L. & Temple-Smith, M, 2011). Woman’s advocate, writer and speaker Melinda Tankard- Reist discusses in her DVD Too Sexy Too Soon that our society tells young girls their primary value is being on display sexually. Our society has created a culture where sexualisation of young girl is regarded as normal (Tutorial DVD). Jean Kilbourne and Diane Levin, authors of Sexy So Soon, argue: Boys are surrounded by media messages that encourage them to judge their female peers based on how they look, often to view them with contempt, and to expect sexual subservience from them (Burton, L., 2012). An interesting anecdote on the evolution of the women’s liberation movement from feminist Anne Manne reads: The relationship between women’s liberation and the new sexual freedom was never an uncomplicated one. The two movements have often been in tension. †¦ Jostling alongside welcome signs of women’s new-found status, and a more relaxed, tolerant, open and liberal society on sexual matters, many of the contours of the new sexual liberalism remain shaped by male dominance (as cited by Burton, L, 2012). Ms Manne (as cited in Butron, L, 2012) goes on to say that â€Å"along the way we  allowed ‘sexual liberation’ to be dictated to by pornography†. This view appears to be supported by many females reported in our media today. In the research paper Underage and Over- exposed Burton (2012) interviewed a young girl who said, Look at most girls’ role models. Most celebrities are just out there at parties, getting drunk and having sex with everyone. Paris Hilton – as much as she is a bad role model to us, she is always in the newspapers and stuff like that so younger generations will be influenced by he. There are also the recent antics of child star Miley Cyrus and her almost pornographic performances at the VMA Music awards in September and her raunchy new film clip for hit single Wrecking Ball. Symbolic Interaction Theory  Symbolic interactionists focus on how communication is central to all human interaction and how these interactions create society (Carl, J & Baker, S, 2011). This theory would view sexting as youth exercising their power to create society. These youth are developing their own standards of what is normal and acceptable behaviour (Carl, J & Baker, S, 2011). Youth consider sexting an adult or media-generated concept (University of New South Wales, 2013, p.1). Youth do not call this activity sexting, but refer to such behaviour as taking noodz, naked selfies, dirty pics or sexy pics (The University of Melbourne, 2012). However, although this creativity and individualism may be acceptable within subgroups, such as the youth subculture, on a macro level it often conflicts with the norm (The University of Melbourne, 2012). Symbolic Interactionist Chafetz argues that men and woman communicate differently: men tend to dominate conversation and woman follow arbitrary rules that men impose. She says â€Å"Women use body language in ways that weaken their ability to assert themselves, this makes them appear less powerful than their male counterparts† (Chafetz, 1997 as cited in Carl & Hillman, 2011 p. 86). Men and woman often act in a default manner associated with stereotyped gender roles. For example, woman use body language and gestures, or in this case nude images, whereas men tend to be more direct displaying their masculinity  by demanding these pictures from their female counterparts (Carl & Hillman, 2011). Sexting is a good example of the manifestation of how an individual’s definition of gender develops from everyday interactions (Chafetz 1997 as cited in Carl & Hillman, 2011). In today’s society, we are flooded with sexually explicit material and people appear desensitised. Psychologist Andrew Smiler stated A porn aesthetic pervades culture – in fashion, music, entertainment and behaviour. This is evident in the billboards, music videos and designer stores that shape the desires and imaginations of a younger and younger demographic. It is not just that culture has become more sexualised. It is that the imagery of the pornographic erotic has shaped the sexualisation of culture. (Smiler, A as cited in Burton, L, 2012). Research conducted by Hewlett Packard found that what is communicated visually has more impact than any other form of communication. Their research supports the idea that visual communication can be more powerful than verbal communication, suggesting in many instances that people learn and retain information that is presented to them visually much better than that which is only provided verbally (Hewlett Parkard, 2004, â‚ ±1). Sexual images are everywhere, often without words, and are creating a whole new set of community values. These images are encouraging our young people’s sexual exploration and thus reinforcing the behaviour of sexting. Australian Institute researcher Flood stated that the â€Å"‘regular and frequent exposure to sexual content in mainstream media produces greater sexual knowledge and more liberal sexual attitudes among children and young people†. Although the media operate at the macro level their influence permeates through to a micro level, thus influencing the way individuals communicate. Symbolic interaction provides a useful explanation of how the sub-culture of sexting has developed. Effects of Sexting Social and Emotional Youth are readily involved in this activity but are naà ¯ve as to its consequences. According to Goodings and Everaardt (2010) as cited in of  the Parliament of Victoria Law Reform Committee Sexting Inquiry (PVLRCSI)), 2013 the â€Å"social ramifications can be the most damaging when it comes to sexting†. The case of Jessica Logan an 18 year old student in America demonstrates the dangers of sexting. The images she sent to her boyfriend were later distributed to hundreds of people and ultimately ended in her suicide (Forde, L. & Hardley, S., 2011). Although most cases are not as extreme as Jessica’s, the mass distribution of these images is common. There are many other detrimental physiological, emotional and social (Goodings and Everaardt (2010) as cited in the Parliament of Victoria Law Reform Committee Sexting Inquiry (2012). Sexting is a dangerous activity and unfortunately â€Å"the viral spread of these images and the associated shame have reportedly led to social, psychological and legal consequences for victims† (Katzman, 2010). Legal Owing to the rapidity of technological development, practices such as sexting are not adequately covered by Australian law. This is known as ‘cultural lag’(J, Carl, S Baker, Scott, Hillman & Larwrence, 2011). Young people who send and receive sexually explicit images may find themselves in serious trouble under various state and Commonwealth child pornography laws. One specific piece of legislation is Part 10.6 of the Commonwealth Criminal Code Act 1995, which makes it â€Å"an offence to access, transmit, publish, possess, control, supply or obtain child pornography† (Forde, L. & Hardley, S., 2011). Furthermore in Queensland, those being convicted of child pornography may also be added to the Sex Offenders Register. Sexting also falls under the category of sexual harassment under S28A of the Commonwealth Sex Discrimination Act 1984 (Forde, L. & Hardley, S, 2011). These laws are designed to protect children from the abuse of adults and many agree that they are ill suited to the issue of youth sexting each other (Forde, L. & Hardley, S, 2011). Those working with children would need to be aware that if they confiscate a data storage device containing such images, or if such images are stored on a school device, material they can also be charged (Forde, L. & Hardley, S, 2011). My Role As a youth worker I would be involved at a grassroots level in mentoring and supporting of youth involved in this practice. I would also want to be involved in sex education classes. According to experts it is vital to include youth’s opinions and ideas if effective solutions are to be found (Walker. S., Sanci, L. & Temple-Smith, M, 2011, p.8). As a youth worker I need to facilitate this and make sure that youth are given this voice. Christian Youth Work Perspective Adolescence is a time of life where humans are forming their identity (PBS, 2011, â‚ ±1). Young people are searching for truth, purpose and belonging. Many youth do not have any authority in their life instructing them on how to build and maintain healthy relationships and therefore are more likely to be involved in risky relationships (Burton, L, 2012) Christian youth workers and chaplains have a great opportunity to be in schools educating youth on topics such as identity, purpose and healthy relationships. As a Christian youth worker I want youth to find their true identity in Christ and that they ultimately belong to him. This truth is the most empowering knowledge any human can have and it answers these questions of identity, truth and purpose. Christian Evaluation From a Christian perspective the act of sexting would be seen as sexually immoral behaviour and thus frowned upon because it would contain images that would be considered pornographic. There are countless references to such behaviour in the Bible to support this. In 1 Corinthians 6:18 Paul writes; Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body. Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies (NIV). Paul reiterates the sin of sexual immorality in 1 Thessalonians 4:3-7; It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control your own body in a way that is holy and honorable†¦ The Lord will punish all those who commit such sins, as we told you and warned you before. For God did not call us to be impure, but to live a holy life (NIV). The message version of Ephesians 5:1-4 provides an excellent example of how healthy relationships are important and without good understanding of them people fall into the trap of immoral behaviour. Watch what God does, and then you do it, like children who learn proper behavior from their parents. Mostly what God does is love you. Keep company with him and learn a life of love. Observe how Christ loved us. His love was not cautious but extravagant. He didn’t love in order to get something from us but to give everything of himself to us. Love like that. Don’t allow love to turn into lust, setting off a downhill slide into sexual promiscuity, filthy practices, or bullying greed. Though some tongues just love the taste of gossip, those who follow Jesus have better uses for language than that. Don’t talk dirty or silly. That kind of talk doesn’t fit our style. Thanksgiving is our dialect. However, it is not the role of Christians to judge the youth involved in this behaviour, but to encourage them to change this behaviour because it is dangerous. The role of Church should be to promote healthy relationships and demonstrate Christ’s love. Recommendations A community approach is needed if sexting is to be effectively reduced. Parents and the education system need to work together with the youth in order to tackle this issue (Walker. S., Sanci, L. & Temple-Smith, M, 2011). The problem could be addressed through: 1. Sex education classes that include advice on (a) the development of healthy relationships, (b) the dangers of sexting and (c) sexual morality and self-image (PVLRCSI, 2012, p.8&9) and (Funnell, N, 2012). 2. Providing seminars for guidance officers, counsellors and chaplains in schools to assist them in addressing this issue with their students (PVLRCS, 2012). 3. Incorporating the voice of youth into the attempts to address the issue of sexting (Walker. S., Sanci, L. & Temple-Smith, M, 2011). 4. Schools providing education for parents on the issue of sexting. This should include, (a) the various consequences of sexting, (b) the legal ramifications and (c) how they can impose restrictions on technology more effectively (PVLRCS2012, 2012). 5. Providing a government community service announcement on this issue be, e.g. a television advertisement campaign. 6. Updating the law need to address sexting appropriately. 7.

Population control in China

In 1950's China, under the government weakened by its countries opium dependence to westerners, the idea still existed that, â€Å"A large population gives a strong nation† This lead to China's population growing very rapidly, so rapidly in fact that this phrase was beginning to prove in correct. As china's population struggled to feed it's self, as well as extreme overcrowding especially in its cities. The death rate in china dropped (except for a blip in the natural decrease caused by a minor famine in the 1960's) and its birth rate continued to grow rapidly. Even after the government implemented tolerant population control policies, for example the â€Å"later longer fewer policy†. The hope was that if people were encouraged to wait longer before marrying, they would have children later in life and therefore is much more likely to have fewer children. However this did not produce dramatic enough results to help slow China's rapidly growing population and end its pending famine crisis. This is probably due to: a) People were still living in a very traditional way. This meant that people, especially those living in rural areas, they had big families. To make up for what was ah high infant mortality rate, during famine years. b) Women were not educated, and were considered the inferior sex whose job was in the home. They had no career so their only job was in the home. c) Being a developing country, and at that time very anti- western ideas, and almost fearful of the western world, Chinese people had little or no access to contraception, and even less education on birth control and family planning. d) No state pension meant that elderly people had to rely on their children to provide for them in their old age. So to be insured of safe elderly years they had to have at least one child who survived childhood and grew up to make an income. In this case boys were preferred, as they could have a paid job, not one in the home. e) A Cultural Revolution made the population increase by 55million every three years; this is nearly the same as the entire population of the UK. In the 1959 to 1961, a famine caused but an Industrial Revolution triggered the government to launch its first population control policies. People moved away from rural areas and their traditional work as farmers to towns and cities, to work in factories, often owned by western countries brought to china by cheap labour costs compared to the western world. This influx of western ideas thwarted the government's campaign, as the later longer fewer Policy was not considered attractive by the Chinese population who moved towards a western ideal. But the government continued and by 1970, State Family Programmes had been introduced. This lowered the population growth rate. In 1978 3 children per family was average but the government persisted, as this was still too many. This was in the form of various advertising campaigns, however their effect was not dramatic enough, and in 1979, the government wished to stamp out population growth completely. So they introduced a strict population policy. The policy used a â€Å"carrot and stick† method to encourage families who participated, and punish those who did not. Encouragement was in the form of great incentives from the government. These included free education for the child, priority housing, family benefit and a state pension for the family. There were also high penalties for having a second child. Including loss of all incentives, and benefits and fines of up to 15% of the family's annual income. This more than halved the birth rate per thousand from 40 per thousand to 17 per thousand. But the government continued further, the legal age for marriage was raised to 22 for men and 20 for women, to marry couples also had to apply to the state for permission. State permission was also required to have a child. Abortions became compulsory for the second pregnancy. Chinas population policy had been very successful at reducing population growth, it met targets set for 2000 in 1994. However the population policy had serious implications for the natural balance of population. The Chinese population has an entire generation of â€Å"little emperors† the title given to the supposedly spoiled, greedy, bad-tempered, lazy children of male only children. More seriously as young men this generation has difficulty finding a wife. This is a result of Chinese ideal of male supremacy. Families would try and find out the gender of the child before it was born, with the option to terminate if it was a girl. If a families first born child was female, it was at times abandoned so that the couple could try again for a boy. The Chinese government also commissioned teams to go from village to village providing a sterilisation service. This at times was a very unfair method and often breached human rights. As the teams were paid by the number of operations they carried out. So often women were sterilised against their will. In Chinas anti-feminist society it was almost always that women were sterilised instead of men. The government would defend their actions saying that there was a serious need for rapid population control or there would have been further suffering to the people. Credit can be given that the scheme worked and met target before time. Today regulations on population control have been relaxed mainly due to the fact that all targets have been met. But also because of pressure from the west. This is mainly in rural areas of china where children are still a useful form of labour on farms, so two children is permitted. But in industrial regions one child is still most likely. Sterilisation is now provided in a manner that is less likely to be damaging and in breach of human rights.

What argumentation levers can you use to influence those who disagree with you? An argument I can lever to influence those who disagree with me is have them place themselves in the position of employer and ask if they would allow John’s behavior to be categorical imperatives. Would they be willing to universalize stealing from company? Allowing everyone to steal, even a little will lead to a huge negative consequences which is proved from slippery slope fallacy. Carr is all about bluffing and deceiving in business, but even he would not agree with this because it is illegal. 4. What is your most powerful and persuasive response to the reasons and rationalizations you need to address? To whom should the argument be made? When and in what context? My most persuasive response is imagine the business world where employees are allow to steal from employers, what kind of culture would that create? A moral hazard one because people wouldn’t have to be accountable for the negative consequences caused by their action. This argument would be made to John as soon as possible, outside working hours and in a private setting. John is probably too motivated by blindness that all he is seeing is quick cash and not the long term consequences he is causing the company.
