Born For Liberty by Sara M. Evans Essay Example for Free

Born For Liberty by Sara M. Evans Essay The Introduction part of the book Born for Liberty by Sara M. Evans is the written path of being informed of the History of Women in America. As it is mentioned in the first few pages of this book, there is a lack of information that we need to fill in ourselves. We have all heard from many historians specially, that our World cannot take the right direction if it finds its past obscured and hard to be seen! I believe a lot of things are connected to each other, and history is one of the most relevant part of our globe and the reason being is because we depend on what our ancestors had been through! The fact that I am using the word depend might confuse you by giving you the wrong idea! In the past, there have been a lot of wonderful, but without forgetting to mention the not so pretty moments that people have lived years ago! Historians are the ones who are willing to examine and study the roots of out life in order to offer us the opportunity to improve our chances of the event that might happen again as it usually does when there are pieces of the puzzle missing! We learn from what had happened to our ancestors, and this way we figure out something else that should improve our life, and diminishing the chances of something ugly to happen again! I guess, all of us know that there has been an abundance of distinct wars in many different countries, and as the years are going by we are reducing the numbers of wars around the world and that is because we learned from the others mistakes! Now going back to the main topic, the history of Women in America, there is a great deal to talk about! Everybody, even my little sister can notice that women are kind of excluded from our History and it has always been that way till now! There was always this vision we had in our minds, that there was always a HE rather than a SHE! We always viewed women as weak creatures designed only for housework, and offering pleasure to the man she stands by! If you have noticed, the fairy tails and the other old stories we have heard during the years we grew, there was always the prince, the hero, the superman, etc! Well, I think it is time for us to have a look at the female part of the world and try to accept their accomplishments during the years that have passed! Women were always excluded from most formal public roles, and as the years passed they learned how to be heard and Sara M. Evans  supports really well this idea by giving a good example of this that is mentioned in the introduction part of the book when it says: The most extreme example is the women of Salem, Massachusetts; as accused witches, accusers, and witnesses, these women held an entire colony in thrall for months (Evans 4). There have also been feminist historians who have dedicated their lives primarily to clear the bad opinion people saved relating to women. Now it is more than obvious and lucid that women have really shaped the broader history and they have given it the flavor it lacked back then! They were the ones who helped to solve the uncountable problems the government had with the immigrants, the ethnic problems and the other ones that would still be present if it wasnt for the intellectual women who set goals to themselves! This is what Sara M. Evans is trying to explain in her book Born For Liberty!

Toulmin Analysis of Attraction Essay -- essays research papers

Toulmin Analysis of â€Å"Attraction†   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  In â€Å"The Mystery of Attraction,† Harville Hendrix claims that attraction between human beings is based on a number of factors that ultimately leave human beings baffled on exactly how humans experience such intense emotions as seen in romantic love and why so many couples tend to have complementary characteristics. He supports this claim by explaining several theories of attraction. His biological theory of courtship states that â€Å"we instinctively select mates who will enhance the survival of the species† (483). This theory suggests instinctive evolutionary attraction such as a female’s rosy cheeks on a slender frame and a male’s muscular physique are the features which take paramount importance in mate selection. Another theory, which he calls the exchange theory, emphasizes that â€Å"we select mates who are more or less our equals† (483). This theory proposes the act of mate selection as being a game of weighing the po sitive and negative characteristics in hopes of attaining equality in all aspects of both mates. His final idea, which is called the persona theory, â€Å"maintains that an important factor in mate selection is the way a potential suitor enhances our self esteem† (483-484). Attraction as it pertains to this theory places emphasis on what others think and the image of how others perceive someone with a certain mate.   Ã‚  Ã‚  Ã‚  Ã‚  Hendrix’s argument has one warra...

Ccea as Biology Coursework: an Investigation to Measure

An investigation to measure the percentage light transmission, using a colorimeter, through a solution, from pH 2 – pH 9, in which jelly cubes were immersed over a 24 hour period Interpretation Written Communication of the Data C1 Pepsin is an enzyme that works in the stomach and has an optimal pH between pH 1 and 4 or in acidic conditions. From our graph it can be seen that that the lowest mean percentage light transmission for pepsin is when the buffer has a pH of 2. Trypsin is an enzyme that works in the small intestine and has an optimum pH between pH 7 and 8 or in neutral conditions.From our graph it can be seen that the lowest mean percentage light transmission for trypsin is when the buffer has a pH of 8. C2 and C3 As the pH of the pepsin buffer increases from pH 2 to pH 9 so too does the percentage light transmission through the buffer solution after a 24 hour period. Although when the trypsin buffer has a pH between pH 2 and 8 the percentage light transmission through the buffer solution after a 24 hour period decreases, but from pH 8 to pH 9 the percentage light transmission through the buffer solution after a 24 hour period increases. At a low pH (pH 2) the amount of gelatine broken down by the pepsin is high.We can tell this as this is when there is a low mean percentage light transmission (16. 86%) because a lot of colour of the jelly will leak in the solution causing the colour to be deeper. But at a higher pH (pH 9) the amount of gelatine broken down by the pepsin is low. We can tell this as this as there is a low mean percentage light transmission is high (34. 14%) because a little colour of the jelly will leak in the solution causing the colour to be lighter. At a low pH (pH 2) the amount of gelatine broken down by the trypsin is low so this means there is a high mean percentage light transmission (41. 5%) because a little colour of the jelly will leak in the solution causing the colour to be lighter. At a high pH (pH9) the amount of gel atine broken down by the trypsin is high so this means that there is a low mean percentage light transmission (29%) because a lot of colour of the jelly will leak in the solution causing the colour to be deeper. C4 and C5 An enzyme is a biological catalyst which speeds up a chemical reaction without itself undergoing a permanent change. Most enzymes are globular proteins and contain active sites. The active site is the part of the enzyme which combines with the substrate.Enzymes are specific which means that one enzyme will work on one substrate. All enzymes work best at a particular pH, their optimum pH. The proteins structure of the enzyme is altered in a more alkaline or acidic solution than the specific optimum pH. When an enzyme structure is altered it cannot fit successfully with the substrate. Activity is therefore limited to a few enzyme molecules that are still unaltered or may totally stop. The protein digesting enzymes, pepsin and trypsin, will hydrolyse the substrate, ge latine. This substrate is a major component of jelly.When a coloured jelly, such as raspberry, is exposed to a protein digesting enzyme, the colour is released into the solution as the gelatine is broken down. The intensity of the colouring released into the buffer can be estimated with a colorimeter. Trypsin is often found naturally in neutral or slightly alkaline conditions. Therefore the most enzyme activity and most colour is released from the jelly would be expected at a pH 7 or 8 and in solutions above or below this pH there would be less colour released. Pepsin is often found naturally in very acidic conditions.Therefore the most enzyme activity and most colour is released from the jelly would be expected at a pH 1 or 2 and in solutions above or below this pH there would be less colour released. Evaluation D1 I consider my results to be appropriate in meeting the aims of the investigation because we used a colorimeter. This measures the percentage light transmission as a nume rical value. It is more appropriate than measuring the light intensity by eye as some of the results looked extremely similar and it could be hard to distinguish between samples.It is also more appropriate than measuring the percentage change in mass of the jelly cube before and after the 24 hour period as it is difficult to extract what is left of the jelly and it is not as accurate. D2 In order to try to obtain accurate results a number of procedures had to be carried out; †¢ Firstly, we used the same specimen of jelly. Although the jelly is from the same company there could be a difference in the composition of gelatine. If this was allowed to happen it could mean that it would take longer to break down some samples than others.This would then affect the overall results of the experiment as it would create an anomaly. †¢ Secondly, we also used a colorimeter which is extremely accurate when it comes to measuring the percentage light transmission. As it measures the perce ntage light transmission as a numerical value. †¢ Thirdly, we only handled the side of the cuvette as if we touched the front where the light passed through it would affect how much light passed through as it will leave a finger print on the glass and make it harder for the light to pass through. †¢ Fourthly, we kept the temperature at a constant 25 °C using a water bath.At low temperatures, an increase in temperature causes an exponential increase in enzyme activity. This is because an increase in temperature provides more kinetic energy for the collisions of enzymes and substrates, so the formation of enzyme-substrate complexes increases. At high temperatures (above 40 °C), an increase in temperature causes a sharp decline in enzyme activity. This is because the bonds holding the tertiary structure of the enzyme are broken and so the active site is denatured. †¢ We tried to use the same amount of jelly as this could affect the substrate concentration.If the surf ace area of the substrate increases it means that it has an increased substrate concentration. As the substrate concentration increases so too does the enzyme activity. This is because a greater concentration of substrate increases the chances of collisions and the formation of enzyme substrate complexes. D3 Although the experiment was as fair as it could have been, there were some factors that were beyond our control; †¢ Firstly, we could not accurately cut the cubes into equal sizes as we did not have the equipment to make a straight incision.This would increase the surface area of the substrate which will increase the substrate concentration. This would increase the enzyme activity as it will increase the chance of collision between the enzyme and substrate and more enzyme substrate complexes can be formed. †¢ Secondly, we could not check the temperature of the water bath on a regular basis as the experiment was carried out over a 24 hour period. If the temperature had went above 25 °C it would increase the rate of reaction as it provides more kinetic energy for the collision of the enzyme and the substrate, so the rate at which enzyme-substrate complexes form is increased.Although, if the temperature decreased below 25 °C it would have the opposite effect. It would slow the rate of reaction as it will provide less kinetic energy for the collision of enzymes and the substrate, so the rate at which enzyme-substrate complexes form is decreased. D4 and D5 My experiment is reliable as it was repeated six times in the form of the pooled class result and all of the results seemed to follow the same general trend. Although, if we had more time we may have been able to do the experiment again which would make the average or mean more accurate.However, there were a few anomalies among the group results. As you can see from table 1, in the test for trypsin at pH 9, group 2’s result decreased from the previous result (pH 8) whereas every other gro up increased except for group 3 who’s stayed the same as the previous result (pH 8). This could be caused from a fingerprint being put on the cuvette where the light passes through; this could lower the percentage light transmission through the solution as it will cover the glass.

The Rise Of The American Revolution - 2123 Words

After helping the colonists defeat the British in the American Revolution, France faced incredible debt. The king looked to an Assembly of Notables for help in repaying this debt, but they refused to aid him. Out of options, the king called the Estates General so that they would levy taxes in France. The Estates General was formed by members from each of the three Estates: the 1st Estate, which was comprised of the clergy; the 2nd Estate, which was comprised of the nobility; and the 3rd Estate, which was representative of everyone else in France. Excited by the prospect of getting involved in government, the 3rd Estate representatives did not just want to levy taxes for the king. The representatives from the 3rd Estate wanted to become a permanent fixture in government, so they broke off from the Estates General and called themselves the National Assembly. The National Assembly took an oath -- the Tennis Court Oath -- to not disband until they had created a constitution for France. T hey established a constitution and the legislative assembly convened, and they were in charge for about a year. However, once the National Convention abolished the monarchy and the King was executed, the government faced being controlled by radicals who would implement a Terror. The Terror officially began when the Convention declared it, but some events leading up to the Terror that could be considered a part of it happened before that declaration.
