Living in sin by Adrienne Rich Essay Example for Free

Living in sin by Adrienne Rich Essay Being a woman is different from being a man. Women do have difficulties living with men. In the poem Living in Sin, the author, Adrienne Rich, has showed the difficulties of their life, and the horrible relationship through her figurative language, and imagery. The imagery reveals the difficulties and differences between men and women. First, she has A plate of pears, a piano with a Persian shawl, in her life. A plate of pears represents the sweetness of life. She expects she will have a sweet life, a great relationship with her mate. Secondly, a towel to dust the table-top, and let the coffee-pot boil over on the stove has shown that she has to take care of everything in the house. She uses a towel to clean the table. This shows her annoyance from cleaning, and she cleans the table carelessly. Finally, By evening she was back in love again, she woke sometimes to feel the daylight coming like a relentless milkman up the stair. These two lines contain both overstatement and irony. When the night is coming, she feels relax and back in love because she finishes all her work, and she can take a rest. Contrarily, when the morning is coming, she feels disappointed because all the annoying things will happen again. The carelessness of her mate makes her feels bad and she will no longer stay there.

Exchange and Transport in Protozoa :: Biology

Exchange and Transport in Protozoa The exchange of gases between the environment and cells occurs via the process of diffusion. Diffusion depends on:  · The amount of surface area available for diffusion. The larger the surface area the greater the rate of diffusion.  · The concentration gradient. An organism which respires very quickly will have a much lower concentration of oxygen in the cells and a higher than normal concentration of Carbon Dioxide. So the greater the concentration gradient across the respiratory surface the quicker the rate of diffusion.  · The thickness or length of the diffusion path. The greater the thickness of the path the slower the rate of diffusion because the gases will have to travel a larger distance. So the respiratory surface must be as thin as possible. The relation of the three points above can be summed up by Fick’s Law: However, the amount of gas which an organism needs to exchange is greatly proportional to its volume, nevertheless, the amount of gaseous exchange which takes place is proportional to the surface area over which the exchange happens. For single celled/unicellular organisms the surface area to volume ratio is large, however, for larger organisms the surface area to volume ratio decreases. The larger the object gets the more complicated it gets. The smaller the object the larger the surface area to volume ratio. This is where single celled organism have an advantage. Organisms like Amoeba can exchange gases with environment quickly and easily. However exchange surfaces need to attain certain properties to maximise gaseous exchange. They are:  · Need to have a good blood supply- high concentration gradient  · Moist- Dissolve gases  · Large Surface Area  · Thin walls  · Permeable As single celled organisms are small so they do not have to have specialised systems like much larger organisms like mammals. Single celled organisms like amoeba do not have to have transport systems or specialised systems because they are so small so [IMAGE]substances do not have to travel far to get to their desired destination. The contractile vacuole in this amoeba is used for water regulation.

A Report That Examines The Role Of Expert And Lay Knowledge In Understanding And Managing Risk

This report is going to examine how risks we face in our daily lives rely on different forms of knowledge to create an understanding of them and their consequences. This report will examine how people use expert and lay knowledge about risks in order to live with them. A brief description of risk is provided. The discussion focuses on how we live with risk and interpret expert and lay knowledge regarding risk and risk avoidance. It is also suggested that people make their own choice as to what and how they use information and to what degree of risk they consider acceptable in their lives. This is influenced by the knowledge they have and how they interpret that. Clearly an expert will be in a stronger position to accurately assess risk compared to a lay person. 1. Expert Knowledge – someone that has knowledge, skill and is qualified in a particular subject. 2. Lay Knowledge – someone who does not have specialized knowledge or training in a subject. This report will examine three examples of risk and will detail not only expert information but it will review lay opinion as well. 1. Firstly the cycling and the benefits of wearing helmet will be assessed. 2. Then a case study that detailed an allotment and the hazardous substances found in the soil. 3. The last risk to be observed will be sun exposure, sun tanning and risks and how consumerism can play apart in forming our choices. 1. Our Risky Lives 1. Risk – a state in which there is a possibility of known danger or harm, which if avoided may lead to benefits (Carter and Jordan, 2009). Almost everything we do in life comes with some degree of risk. It is how we interpret the risk that determines how we live. Some risk is taken without thinking, some risk is unavoidable, and in other cases we can reduce the risk or avoid the risk all together. 1. Cycling and the benefits of wearing a helmet Cycling will introduce the idea of risks and risk management in our material lives. Cyclists manage their risk with lights, occasional hand signals and helmets. Cyclists have to negotiate the use of the helmet, whether or not to wear one but not doing so means any injury sustained may be the cyclist’s own fault. One study shown 85 per cent reduction in the risk of head injury among cyclists who wore helmets (Thompson et al., cited in Carter and Jordan, 2009). Other research found that, when car overtakes a cyclist, the car comes significantly closer to a cyclist who wears a helmet (Walker, cited in Carter and Jordan, 2009). Taking both studies into account seems to suggest that if you wear a helmet then you are more likely to have an accident but if you have an accident then you are less likely to have head injuries. 1. Hazardous substances found in the soil Soil on an allotment will show how knowledge of an invisible risk is produced by experts but can be contested and how the allotment users used knowledge to manage the risks. The benefits of a social activity such as gardening were suddenly brought into question by publication of a scientific test on the soil. The material environment changed from being good into something that was dangerous. The soil was safe then became poisonous and then become safe again, all without the soil itself being changed. The existence of two soil tests confirms that even within science there are debates over how best to assess risk. In the case study, the same soil shifted from being safe to dangerous and back again solely as a result of different measurement practices (Carter and Jordan, 2009). This shows how the expert knowledge may or may not influence the decisions people make about managing risk. Gardener did not listen to expert knowledge about safe soil, because two contrasting results of the tests did not feel quite trustworthy. 1. Sun Exposure and expert knowledge of sun risk The last risk to be assessed will be sun exposure and sun tanning and risks. Increasingly over the last number of years dangers of sun exposure and tanning have come to the fore. Even though advice and evidence which has been produced people still continue to expose themselves to the harmful UVA rays. In this section we can look at a second case study of risk and risk management concerning holidaymakers and their attitudes to a tan. To understand the apparently risky practices connected with sun exposure we have to take seriously the ways in which people make sense of expert advice, and measure it against their own knowledge and experiences of the material world in which they live (Carter and   Jordan, 2009). The research conducted by Simon Carter used a mixture of interviews and focus groups with tourist aged 20 and 35 years of age who regularly travelled abroad for holidays. The first thing that this search found was that people could recall health education advice by seeking shade, using a sunscreen or covering the body. People knew what the expert advice said about the dangers of sun. However, people did not fully follow this advice because they had their own ways of understanding and making sense of the healthy and risky elements of their material lives. The knowledge produced by experts was different from that produced by holidaymakers. This distinction between expert and lay knowledge meant that expert knowledge was interpreted rather than followed to the letter by the public (Carter and Jordan, 2009). The expert knowledge does not straightforwardly determine public opinion. 1. Lay knowledge of symbolic risk The effects that the sun has on the body are both a source of material risk, from cancers, and of symbolic risk, such as being peely-wally (Carter and Jordan, 2009). Suntan became a material sign or symbol that is for the visual consumption of other tourists. 1. Beck’s thesis . The examples of sun exposure and of poisoned soil demonstrate how we may have entered into a particular kind of relationship to risk in society today. German sociologist Ulrich Beck examined the move from the Industrial Society in which political deliberations where concerns with the distribution of wealth to a Risk Society that focuses on the distribution of harm (cited in Carter and Jordan, 2009 p. 80). Beck also argues that we have become dependent on external information usually expert knowledge to assess the risks we face, instead of using personal experience or common sense. For example, the allotment holders could not determine the risks contained in their soil, they were told about potential danger by scientific experts. Similarly, the possible risk from sun exposure has to be made clear to people by expert evidence. One of Beck’s main concerns is the role of expert knowledge in defining the risks, whether that risk is nuclear radiation, arsenic in the soil or the sun. 1. Conclusion In modern society much more effort is being put into measuring risk. Experts aim to examine potential hazards and produce evidence that will allow us to make informed decisions. Assessing risk often relies on science and expertise. These are practices which involve choices and assumptions that can create debate. A risk society is one in which calculations of risk become increasingly prominent. Many modern risks are invisible and need experts to make them visible to the public.

Essay about Why Pornography Shouldnt Be Banned - 1218 Words

Why Pornography Should Not Be Banned It seems to me there are two ways of defending pornography. The first is pornography does not harm anyone, and so it should not be banned. The second is pornography cant accurately be identified between what pornography is and what its not. With these two main points I will prove pornography should not be banned. Pornography does not harm anyone. In mainstream pornography, all parties are willing participants. The women who grace the pages of Playboy, Penthouse, Hustler, Swank, etc. are paid to do so. They have entered into a contract in which they sell their services. Their services in this case are the displaying of their naked bodies for the masturbatory delight†¦show more content†¦Indeed, the real harm would come in taking away an opportunity currently available to them (probably the most efficient opportunity currently available to them) to make money. We can never draw the line accurately between what is pornography and what its not. The problem comes when the government or public are of the opinion that it is wrong. When that happens, they attempt to identify what is pornography, and what is art. Those who try to define pornography (and who want so-called art like Lady Chatterleys Lover and Michelangelos David excluded from that definition) will typically create some sort of test to define the difference between pornography and art. This is no answer at all. One of two arguments will defeat it, depending on ones viewpoint. For example whether a particular piece of would-be-pornography is art or not is determined by the creator or a consumer. A certain piece is defined by what the creator intended it for or by what consumers (government and critics) believes it to be. If the distinction between art and pornography is based on intentions, then the response is that we never can accurately and actually know the intention of the artist. Just as I believe we could never really begin to accurately describe the intentions of our fore fathers when they came up with the U.S. Constitution. If the distinction is based on the interpretation of the courts, then we can accurately say the problem lies with unqualifiedShow MoreRelated We Dont Need Internet Censorship Essay1350 Words   |  6 Pagesthe other.
