One of the major concepts of Marxian Economics is the exchange value. This concept was actually also used extensively by David Ricardo and Adam Smith. Describe the way Adam Smith defines the concept, and then how David Ricardo developed it. Then describe the way Karl Marx developed it further, and how the concept is related to prices according to him. To what degree it is possible to say, Marx built upon what Ricardo wrote. To what extent Marx is different from Ricardo in his definition and use of the concept. How do you think the exchange value concept has influenced the way these three economists approach to the economic system?

Suppose that call options on a stock with strike prices $120, $140 and $160 cost $13, $14 and $18, respectively. How can the options be used to create a Butterfly spread?

Call 1 – Strike $120: Position Long or short?__________

Call 2 – Strike $140: Position Long or short?__________

Call 3 – Strike $160: Position Long or short?__________

                  I.            Explain how you can built the spread and write a table that shows the profit and payoff for each option and total spread.

                II.            When is the Maximum profit? How much?

              III.            Draw a diagram for the spread showing the total value of the spread and both call options.

True or False

41. There are only two things a company can do with its profits, pay dividends and retain profits.

42.The investment cash flows for a project typically carry a positive sign.

43. A positive of NPV is its currency units.

44.A project uses the WACC of the country where the capital is raised regardless of where the project is built.

45.The CAPM approach is too difficult to be used often as a project's cost of equity.

47.Flotation costs are a measure of how much it costs to raise funds.

48.A board of directors oversees executives in a firm.

50. WACC is a measure of a company's marginal cost of new funds.

Assuming Database is not providing Referential Integrity Constraints support i-e Primary key, foreign key and Unique key, your task is to design a database engine with your own built in Referential integrity rules implementation and you need that only one database connection is maintained which an application should access.

Recommend proper design pattern used for the stated problem. Give reasons for selecting that pattern, create complete class diagram for the solution. The class diagram should also show the methods of the class and all the relations a class has with other classes. Also provide complete working code of the example

Case Study: The subway is expected to run the whole length of Manhattan. It will eventually connect with the already existing subway, East Side subway. The second avenue subway will also connect with the railroad at the 125th street in the north and run to the southern side to reach the financial district. However, phase one of the project was opened for the public in January 2017. There is a plan to include 16 new underground stations in the subway. These substations will be built using tunnels and cut-and- excavations. This project will occur below and maybe in some of the highly populated urban infrastructures in the world.

Question: Design a detailed agenda for a Kick Off meeting for above case study?

(13)Acme Logistics provides “less than truck load” (LTL) services throughout the U.S. They have several hubs where they use cross-docking to move goods from one trailer to another. Acme built its last hub 10 years ago, and it had 36 dock doors. The cost index at that time was 140, and the total cost was $6 million. Acme plans a new hub that will have 48 dock doors. The cost index now is 195, and Acme will use a capacity factor of 0.82. What is the estimated cost of the new hub?

(a) 8580534 (b) 9580534 (c) 10580534 (d) 11580534

1. During and after the commissioning and turn-over process, the design and construction team need to provide the owner with many important documents for the operation of the building. These include all of the following, except:

   		A list of things that the contractor secretly left out of the building to save costs.
   		Operations and maintenance manuals for installed equipment
   		Final construction drawings, typically called "As Built" drawings. These incorporate any minor changes made during construction.
   		Design calculations for building systems.
   		Warranty, test-and-balance, and inspection documents.
   		Building Information Modeling (BIM) data, if included in the contract.
   		Samples and inventories of spare parts and materials used in the construction, to facilitate repairs.

Four holes must be drilled in a casting which forms the housing for an electric motor. The holes may be located and drilled without the aid of a jig by a skilled machinist whose wage rate is $26 per hour. His production time will be 3.5 minutes per housing. A jig could be built at a cost of $600 permitting the holes to be drilled by a machinist at a lower skill level. In this case the lower wage rate would be $19 per hour and the production rate would be four minutes per housing. Which alternative would you recommend if 2,200 housings are to be produced?
b)The total production cost using no jig with a skilled machinist is?

Case studies offer a practical problem for which you supply a written solution. There is not always a specific right or wrong answer to these cases. They are intended to encourage you to review the chapter material and delve deeper into the topics you have learned.

One of the primary reasons networks were built was to facilitate the sharing of information. Organizations want to share files and printers in Windows, Linux,and Mac OS X. However, organizations need to ensure they maintain secure access to shared files. This is often accomplished using user and group accounts, with assigned permissions. These permissions determine who can access the shared resources and what type of access they have.
