Topic #1 The impact of rapid urbanization on traffic: The increased number of people is migrating to the urban areas that lead to the increased population and traffic as we can see in our day-to-day life there is a problem of overcrowding everywhere we travel.

Topic #2 The increased pollution levels: All over the world there is a problem with increased pollution be it land, air, or water pollution it is ever rising leading to climate fluctuations and problems like an uncontrollable forest fires, unbearable rains, snowfalls, etc.This paper will to draw the connection between our pollution of the environment and the relationship to climate fluctuations.

6. What features are necessary for the cell to engage in facilitated diffusion rather than simple diffusion? Secondary active transport rather than primary active transport (is this different for symport and antiport? What advantages do we derive by putting these modifications in place?

2. Make a concept map of the cell membrane. Include each of the functions of the cell membrane listed below. Make sure each function is correctly linked to the components of the cell membrane responsible for each function

1. separates intracellular fluid (ICF) from extracellular fluid (ECF)
2. provides permeability barrier
3. contains surface proteins acting as antigens - important for recognition of “self”
4. provides cell communication: receptors and signal transduction pathways for hormones and neurotransmitters
5. contains a variety of adhesion molecules allows anchoring, tissue organization
6. acts as a highly selective filter

7. In mythology, the cosmic man appears grossly swollen and may be seen pictures as a human rain cloud. Propose a mechanism whereby this mythological creature could swell up and fill with water. (It is not going to be true, so you can’t look this up – it’s just for fun to see if you understand how it could work.)

1. Purchasing power parity is a neoclassical economic theory that states that the exchange rate between two countries is equal to the ratio of the currencies' respective purchasing power.
2. The OECD defines GNP as "an aggregate measure of production equal to the sum of the gross values added of all resident and institutional units engaged in production (plus any taxes, and minus any subsidies, on products not included in the value of their outputs).”
3. The gross national income (GNI) is the total domestic and foreign output claimed by residents of a country, consisting of gross domestic product (GDP), plus factor incomes earned by foreign residents, minus income earned in the domestic economy by nonresidents.    
4. Unlike GDP, which defines production based on the geographical location of production, GNP indicates allocated production based on location of ownership. In fact it calculates income by the location of ownership and residence, and so its name is also the less ambiguous gross national income.
5. HDI is a composite statistic (composite index) of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores higher HDI when the lifespan is higher, the education level is higher, and the GDP per capita is higher.

TRUE OR FALSE?

Thomas Friedman's book, The World Is Flat: A Brief History of the Twenty-First Century, contends that "the convergence of technology and events that allowed India, China, and so many other countries to become part of the global supply chain for services and manufacturing, [created] an explosion of wealth in the middle classes of the world's two biggest nations, giving them a huge new stake in the success of globalization..." He continued by writing that with "this 'flattening' of the globe (which) requires us to run faster in order to stay in place... (brings us face to face with the reality that) the world has gotten too small and too fast for human beings and their political systems to adjust in stable manner..." Share your thoughts with the class about one of the following questions, all of which refer to "the world is flat" quotation. 1.Are the material incentives in China and India likely to make those middle class workers more supportive of a global economic and cultural system? Why or why not? 2.How do you account for the anti-globalization reactions of terrorism? 3.Are the new opportunities for Asian workers a threat to American workers? (Is this a zero sum situation?) 4.Will political systems be unable to maintain stability? Explain.

The Solow economic growth model generalizes the Harrod-Domar model by modifying the assumption that relates the changes in capital and the changes in output in terms of a neoclassical production function.:

3) Canada in 2013 had 81.1 years of life expectancy at birth, 12.3 mean years of schooling, 15.1 expected years of schooling and an income per capita (GNI per capita) of $35,369. Its New HDI value would be the following (use the same max and min values as the ones used for the Ghana example discussed in class)

Question 5 [Note this question is from the Week 9 Tutorial] a) In Chapter 9 (Week 9 Tutorial) we discussed the integration of the Human Resource Management and Payroll databases. In particular, we discussed different benefits of this integration in the Week 9 Tutorials. Some companies believe in the integration of HRM and Payroll systems. However, many firms do not agree with this integration. These companies maintain separate HRM information systems and Payroll. Required: Discuss both arguments. For this discussion, think in terms of (1) difference in employee background, and (2) functions performed by the HRM and payroll departments. [7 marks] [7 marks. Word limit: Up to 250 words.] b) Mr Peter is the treasurer of a small charity and you asked him to explain the business activities and data processing operations involved in the payroll cycle of the charity. During this discussion, Peter explained that the charity is not using a separate cheque account to manage their Payroll due to the extra monthly services fee. Peter further explained that the benefits of a separate cheque account are not worth the additional fee. Required: As a student of accounting information systems, how would you respond to Peter?

1a. Silicone implant augmentation rhinoplasty is used to correct congenital nose deformities. The success of the procedure depends on various biomechanical properties of the human nasal periosteum and fascia. An article reported that for a sample of 17 (newly deceased) adults, the mean failure strain (%) was 26.0, and the standard deviation was 3.1.
