MATHEMATICAL MODELLING OF INFECTIOUS DISEASES (SIR MODEL) Infectious diseases continue to claim the top spot for morbidity and mortality worldwide‚ with an estimated of 10% of all deaths each year to have been caused by HIV‚ tuberculosis and malaria. Infectious diseases have remained the major cause of suffering and mortality in developing countries‚ perhaps due to the fact that the aftermath of natural disasters often involve the outbreaks of infectious diseases. It is no wonder that the topic

In the essay "Polite but Thirsty‚" Yaping Tang describes her experience as well as the Chinese students’s experience when they first arrive in The United States. The purpose of her writing this essay is to give the ESL teachers who work with Chinese students a comprehensive and more judicious look about the differences between Chinese and American cultures. She explains cultural adjustment process and culture shock in terms of five different customs between the Chinese and American cultures: name

Mathematical Aptitude and a Successful Life! As a thinker‚ I have many different skills‚ but the most important aptitude that contributes to my successful life is mathematical. First of all‚ mathematic has helped me a lot in my home life. For example‚ last year when my uncle bought a house‚ I helped him to minimize the cost of rebuilding the floors. Although he wanted to make the floors by wood‚ he did not know how many box of wood he should buy because the floors did not have any particular shape

that the option sells for 1.20 at time zero. Consider an agent who begins with wealth X0 = 0 and at time zero buys ∆0 shares of stock and Γ0 options. The numbers ∆0 and Γ0 can be either positive or negative or zero. This leaves the agent with a cash position of −4∆0 − 1.20Γ0 . If this is positive‚ it is invested in the money market; if it is negative‚ it represents money borrowed from the money market. At time one‚ the value of the agent’s portfolio

Anselm considers that‚ raising against Ontological Argument from side of creature(human) that was created by creator(God) is absurd‚ however personally I am not the only one who disagrees with this statement. First of all I will summarize Anselm’s Ontological Argument‚ than I will go on to object to his argument through Immanuel Kant’s argument and defend Immanuel Kant’s argument threw the Anselm’s and Rowe’s arguments. The formation of Ontological Argument started in eleventh century by St.Anselm

The Value of Homework for Mathematical Success Erik M. Andersen University of Colorado at Denver Abstract The questions studied in this paper revolve around homework and if the quantity or the content of homework assignments relate to proficiency in an Algebraic unit on Functions. A study was performed on 18 similar ability high school students. The students were divided into four different homework groups and their pre and post-test test scores were compared to see if there was

The fundamental mathematical capabilities of students in Indonesia are still low when viewed from several international studies‚ one of which is the Program for International Student Assessment (PISA) which sees the ability of mathematical literacy. In the last participation‚ Indonesia received a score of 386. This result was still below the average achievement of the Organization for Economic Cooperation and Development (OECD) of 490. The PISA aims to measure students’ mathematical literacy skills

Rethinking Mathematical Vision In reviewing the video by Jo Boaler it has awakened a new perspective about math. Mrs. Boalrer describes how neuroplasticity in the youth can renew itself. Also‚ how synapse may develop differently and are activated at a different time according to how a student gain knowledge to fire up their subnapize. She gives a great example of a London cab driver. They must remember routes consisting of 25‚0000.00 streets and 20‚000.00 landmarks. The research found that their

For this assignment I will describe two theories of mathematical development. I will discuss Jean Piaget’s and Tina Bruce’s theories about how children’s understandings of mathematical develop. Jean Piaget’s research led him to believe that we develop by taking in information‚ which is then processed by the brain and as a result of this our behaviour changes. He stated that there are stages of development that children move through. The ages are approximate but the sequence is the same for everyone
