David, P. (2004). Why discrete Math Is Important. Retrieve 2005, from CESL

2. Summary:
In P. David’s article ”Why Discrete Math Is Important, ” he states that discrete math has been considered the most important approach of mathematics science a few years ago. In the past, discrete math got a little less attention in math curricula of secondary and high schools than other approaches because advanced examinations in schools and tests to enter college didn't depend on them. In contrast, he points out that discrete math has become more and more significant because there are some causes. First, discrete math is necessary to succeed in math materials of undergraduate degrees. Second, most computer experts and staff of accounting firms need to learn it. Third, a student must have enough background in discrete math if he want to compete in math competitions. Also, most problems in discrete math can be solved with a few tactics. Finally, he maintains that materials of discrete math are more interesting than other approaches. In conclusion, a student must learn some important parts of discrete math if he want to study in science departments.

In the ARI J.'S article " Is Gold Really the Safest investment?", she states that why the price of gold increasing and gold is not the safest investment in the world. First, we can know what the relation between dollars and gold is. Second, there is the reason why the gold price increasing in the whole world. Third, the price of gold or the value of gold is unpredictable and volatile. To sum up, the suggestion is that we should not be blind buying gold or selling your jewelry.

I agree with the author's opinion that gold is not the safest investment, because the price of gold is unpredictable. But is a little safer than dollars, especially when the world is in trouble whit financial crisis. I think that is the best way to keep the value of your money is by using all 50% of your money to buy gold and keeping the other 50% of money in the bank. Whatever which side is changed, you always have 50% of the money, and get a chance to earn more money.

In Raimundo Soto´ paper “Dollarization, Economic Growth, and Employment” (*), the author established the effect on employment levels and economic growth, and the relationship between them, after the Government from Ecuador made the decision to eliminate the national currency and use American Dollar in its place. First, he introduces a brief point about the economic situation of Ecuador before and after dollarization. Second, he describes the Econometric Model used to analyze data, which consisted of a multivariable Log-linearizing equation of regression. Then, the author explains the main discoveries when he ran the model for the long and short term, which are high and positive correlations between employment levels and both the Gross Domestic Product and Real Exchanges Rate; on the other hand, the opposite effect was found for the Cost of Capital and Real Wages. He concluded by saying that the dollarization process of Ecuador has been controversial, because it has coexisted with two different effects, and said that in order to increase the employment levels the government will make policies which help the economic growth and avoid fixing a high minimum salary.

Crime statistics reveal little

Danny Shaw (2002, Jun. 13). Crime statistics reveal little. BBC home affairs correspondent. Retrieved Mar. 23, 2009, from

Danny Shaw’s article entitled “Crime statistics reveal little” alleges that the statistic, which shows that in England and Wales a crime happens once per 5 seconds, an arrest occurs once per 15 seconds, can’t tell us the truth. The author points out a big mistake. Although the data was provided from the government, the data can’t use the snapshots directly. Except that they are just a record of one day, no other information can be known. Even though the amount events of wrongdoing, seizing, probation service and Victim Support seemed large, some numbers of them should be cut out, like the shots leading to transfer from one department to another one, cautions and acquittals. We have to know the details for the events, or deeply know how many police staff deal with the events. All factors should be considered for the analysis. So actually the statistics could only be used to promote them for working hard and how large their tasks are, nothing else. The best revised way is using the average daily caseload per year to stand for the snapshots on May 01. That will make the statistics more reliable.
