Explain the formation of a hot spot. (7marks)
Hot spots are anomalies in the pattern of volcanic activity upon plate margins. They are often in the middle of plates.
A hot spot can be described as a small area of the earth’s crust where an unusually high heat flow or plume is associated with volcanic activity. Of approximately 125 hot spots thought to have been active over the past 10 million years most are located well away from plate boundaries. It is the fact that they have posed so much trouble for plate tectonic theories, as they don’t fit with the general trend that most seismic and volcanic activity happens at margins. There are several examples of volcanic activity away from plate boundaries such as Yellowstone national park.
These hot spots are formed by huge columns of up swelling lava because of radioactivity within the earth, these columns are known as plumes. The plume of plastic molten rock that pushes upwards; causing pressure to drop and the plastic thin rock to become molten, melting and pushing through the crust above. These plumes lie in fixed positions under tectonics plates. As the plate moves over the hot spot, the upwelling lava creates a steady succession of new volcanoes that migrate across the plate. These plumes can be up to 1000km across.
The emperor sea mount chain is a good example of plume activity; showing the variation of activity within the succession as the plates move over the plume. This chain extends 5000km along the Pacific Ocean. The first hot spot seen in the chain is the Lohi volcano in Hawaii. Lohi is an active volcano submarine volcano. Due to subsidence and erosion overtime the volcano will become a flat topped submarine mountain known as Guyot. The Hawaiin volcanic island is the next formation in the sequence. This is an active volcano that as the plate moves away from the plume pressure will decrease causing it

Where Spots Are Hot

...Where Spots Are Hot Grand Canyon University: ECN-601 Economics 12/21/2011 Where Spots Are Hot The article “Where Spots Are Hot” addresses an issue of supply and demand in Fairfield Connecticut and the New York City suburbs. The hot commodity in these areas that are causing the residents so much pain and heartache is a public parking pass. The nature of failure in this case is a failure to adequately provide a public good. The article states that in Connecticut there are more than 60,000 commuters that take the train into Manhattan everyday and the stations only have enough parking for almost 20,000 commuters. The others commuters are forced to use more expensive private lots in order to use the same train stations. This is not a new problem for the rail stations this is a problem that have been going on for years. Parking passes to park at the lots run $279-$840 for an annual permit and the waiting list is at least 6 years long with 4,200 to people on it. The other option is fighting for a spot at the private lots at the cost of $1280 annually. Is everyone that is in possession of these golden parking passes actually using them? The answer is no, these residents renew the parking passes yearly whether they have a need for them or not because they are in fear of not having one when the need does arise. Family members are even passing the permits down to other family members once the owner is decease. The article states that in the town of Rowayton there is so much...

Hot Spot Research Paper

...consider when determining “hot spot” locations, especially when the information is coming from a computer or the actual patrol officer who works in the area on a daily basis. Through my training and experience, both are correct and must be respected. The perspective of “hot spots” through analysis and research, as we have come to learn about research is that there is “no perfect research or study.” There is room in the research for bias, miscalculations, in complete analysis or simply the information can be gathered incorrectly. I do not entirely discredit the research; however, it must include the insight of the patrol officers to make the evaluation complete. There is the possibility that the information gathered...

Submit your assignment file on Moodle well on time to avoid system congestions or break-downs during the last minute Problem 1: Tourist spots in London As a tourist in London you want to visit 7 spots and minimize the time spent on visiting these 7 spots. The details of the 7 spots including their ID, time to see the attraction, and opening time are given to you (Range A3:D9 in given spreadsheet). Note that you want to visit each spot only once. Range B13:H19 in the given spreadsheet contains the travel time (in minutes) between any two spots, 9999 stands for infinity. For example: travel from 2 to 5 (Trafalgar Square to Tower Bridge) takes 22 minutes. You can assume that all other times (wait times for transport, queues for attractions etc, are already accounted for in the sightseeing time and travel time). The subroutine calc_schedule uses this information to calculate the route to be taken from the starting spot (given in G3) at the starting time given in G4. The subroutine prints out the route below the travel table (skipping one row to maintain readability) and in the next row, the respective times that you will reach each spot. In-case, the heuristic cannot find a solution, an error message is printed on the spreadsheet. The following ranges on the spreadsheet have...

Hot Spots: Beyond the "Greek Crisis"

...This forum focuses on the debt crisis in Greece (the 2010 EU/IMF “bailout” and subsequent austerity measures), as well as the various challenges that have been posed to the violence of neoliberal “adjustment.” The brief articles presented here have been solicited from observer-participants in the debates and protests, but also in the intimacies and banalities, defining everyday life in crisis Greece. The outlines of the crisis are widely known. Indeed, Greek society and its travails have never before been so visible to the global media eye. The aim of this forum is not so much to fill in this familiar outline of crisis with ethnographic detail as to trouble its parameters. The first section Debt, Responsibility and “Reform” treats debt not as a statistical fact, but anthropologically as a complex discourse on morality, responsibility, obligation and reciprocity. Against the breathless synchronicity of “breaking news” and (endless) speculation on the denouement of the crisis, these pieces insist on historicizing and globalizing. Piercing the blatant Orientalist tropes dominating international and often domestic reporting, they plumb the social, political and economic forces that have led to the current impasse, but also the political efficacy of “crisis” itself in legitimating the agenda of “structural reform.” The second section Precarity and Protest centers on the escalating violence of the crisis and the emergent politics of protest. The December 2008 revolt, which first...

Evaluation

...Intro Speech Evaluation As for my Speech I felt like I did jump right into the topic of what I was about to tell the audience. I could have made my transition a lot better. I felt as if I did have my organization of the speech laid out perfect, but when I actually talked it wasn’t. But everything was in order. For my ending I really just walked off the stage because I forgot everything that I wanted to say. I couldn’t finish all my thoughts. I kept moving around and stayed looking down. I really didn’t make enough eye contact with the audience like I was suppose to. I know for my next speech to get a spot on the floor and just stand in that same spot. Also I am going to pick spots in the audience that I can look at like empty seats, the wall, or even their shoulders so I can look like I am actually looking at them when I talk. My body language portrayed that I was nervous and didn’t know what I was talking about. I felt like everybody could hear my voice but I was still looking nervous. It wasn’t between 2-4 minutes because I had forgot my thoughts. I hated my speech altogether. I couldn’t finish my speech and I was disappointed with myself. I know my audience was looking like what is he talking about from how I kept moving around and looking down at the podium. If I could have did anything different I would have finished my speech all the way. When I prepare for my next speech I am going to come to you way before to get clarity if everything is good and in order...

Parking Permits

...Ashley M. Taylor English 102 Professor Catanese “Pining for Parking spots” Its 7:45 Monday morning and you’re on the road to campus and hoping that a parking spot is available. Not only do students face this dilemma, but teachers do as well. Some professors are tardy to classes due to traffic but what about the major traffic that comes with trying to find a parking spot on campus? The morning rush of various professionals during the day is time consuming and everyone seems to have some place to go and they are in a rush to get there. Students who live off-campus have to worry about the possibilities of having to miss a class as a result of no parking on campus. With this ongoing dilemma directly affecting the students and faculty, I propose that USC opens another parking garage on campus to better accommodate these people. If the University of South Carolina were to build at least two new parking garages on campus, I guarantee that the complaints about the lack of parking on campus would decrease, and attendance by students as well as professors would not be directly affected by the strain of parking spots on campus. As a result of construction of the Patterson dormitory, USC housing has the stressful task of trying to find proper housing for the incoming freshman of the fall semester. The dorms normally reserved for upperclassmen such as East, South and West Quad, as well as the horseshoe apartments are now being occupied by freshmen and upperclassmen must scramble...

Bright Spot Summary

...and Dan Health’s “Finding the Bright Spot” In the chapter “Find the Bright Spots” taken from the book Switch: How to change thing when change is hard, the authors state that: when changing things, there’re bright spots in your field. You need to direct your followers- the Riders by following these bright spots and make the Elephants’ expect that change is possible and the Path is clear. In 1990, Jerry Sternin came to Vietnam to fight malnutrition with barely support from the government. Firstly, his team found that there were a lot of problems such as poor sanitization, poverty, out of clean water. However, in six months and almost no money, solving these problems became useless. After weighting, Jerry found that there were healthy and well-nourished kids despite their poor families. There were his bright spots. Besides that, he directed the mother’s Riders to shadow the bright spots’ mothers. Uniquely, these kids ate four times instead of twice a day, parents fed kids by hands, or mixing rice with small shrimp, crab and sweet potato green provided vitamin and protein for the kids. Because knowledge couldn’t guide the villagers, Jerry created cooking classes at the bright spots’ houses, provided detailed instructions to the mother’s Riders. Gradually, more mothers followed and this made the mothers’ Elephants believe in making their kids healthier. Six months later, 65 percent of the kids became healthier. Bright spots exist in every field that you deal with...

...there are speculators who attempt to capitalize on their expectation of the yen’s movement over the two months between the order and delivery dates by either buying or selling yen futures now and buying or selling yen at the future spot rate. Given this information, what is the expectation on the order date of the yen spot rate by the delivery date? (Your answer should consist of one number.) 4. Assume that the firm shares the market consensus of the future yen spot rate. Given this expectation and given that the firm makes a decision (i.e., option, futures contract, remain unhedged) purely on a cost basis, what would be its optimal choice? 5. Will the choice you made as to the optimal hedging strategy in question 4 definitely turn out to be the lowest-cost alternative in terms of actual costs incurred? Why or why not? 6. Now assume that you have determined that the historical standard deviation of the yen is about $0.0005. Based on your assessment, you believe it is highly unlikely that the future spot rate will be more than two standard deviations above the expected spot rate by the delivery date. Also assume that the futures price remains at its current level of $0.006912. Based on this expectation of the future spot rate, what is the optimal hedge for the...

I Don't

...Problem 3 Now I will explain why the NPVs of these two approaches are different. For Approach A, NPV is calculated using cash flows denoted in Peso and interest rate in Mexico and then transferred into Euro at the lowest exchange rate in 2008, which is 15.99 MXN/EUR. This is equivalent to using a constant exchange rate of 15.99 to transfer Peso into Euro every year. On the other hand, for approach B, cash flows are transferred into Euro every year and NPV is calculated using cash flows denoted in Euro and interest rate in France. Since Peso is depreciating across time, cash flows are transferred into Euro using a series of increasing exchange rates. Cash flows in Approach B are lower than those in Approach A. Therefore, NPV denoted in Euro for Approach B is higher than that for Approach A. Problem 4 If the inflation in Mexico is 3%, which is the same as that in France, the nominal interest rate in Mexico will be the same as that in France according to International Fisher Effect. So the discount rate will be the same. According to the Interest Rate Parity, the exchange rate between these two currencies will stay the same due to the same nominal interest rate. Thus, the cash flows denoted in Euro for these two approaches will be same. Since both cash flows and discount rate are the same for these two approaches, NPV will be the same. You can see the calculations in this spread sheet. Both approaches give you the same NPV if both countries have the same inflation rate. ...

Interest Rate Parity

...Interest rate parity | A theory that the interest rate differential between two countries is equal to the differential between the forward exchange rate and the spot exchange rate. Interest rate parity plays an essential role in foreign exchange markets, connecting interest rates, spot exchange rates and foreign exchange rates. Interest rate parity, or sometimes known as International Fisher effect, is an economic concept, expressed as a basic algebraic identity that relates interest rates and exchange rates. The identity is theoretical, and usually follows from assumptions imposed in economic models. There is evidence to support as well as to refute the concept. Interest rate parity is a non-arbitrage condition which says that the returns from borrowing in one currency, exchanging that currency for another currency and investing in interest-bearing instruments of the second currency, while simultaneously purchasing futures contracts to convert the currency back at the end of the holding period, should be equal to the returns from purchasing and holding similar interest-bearing instruments of the first currency. If the returns are different, an arbitrage transaction could, in theory, produce a risk-free return. Looked at differently, interest rate parity says that the spot price and the forward or futures price of a currency incorporate any interest rate differentials between the two currencies. Two versions of the identity are commonly presented in academic literature:...
