Fall Semester 2015 NMSU Econ 252, Instructor: Dr. Larry Blank Writing Assignment and Critical Thinking Problems: This assignment is worth 100 points toward your overall course average. The criteria used to grade this assignment includes the professional appearance of the document you submit, your ability to use the principles of supply and demand to critically assess the impacts, and your ability to explain your conclusions in writing. Each part can be answered in one page or less. Assigned: October 5, 2015 Deadline: Friday, October 16, 2015 You will email your assignment in Canvas. Before you email your assignment, make sure your name is on your paper AND your full name is included in the electronic file name. For example, filename: Jose Sanchez_Econ252_paper.doc I will not read your work if your name is not in the electronic filename. Assignment: Answers to all parts shall be completed in a Microsoft Word document. Begin by copying the Scenario below and then, for each part, copy the problem before completing your answer. You may want to draw your diagrams in Microsoft PowerPoint or other software and then copy and paste the diagram into the Word document as a “Picture (Enhanced Metafile)” using the “Paste Special” feature in Word. The document you turn in should be six (6) pages long. For the first page include a short title for this assignment, the course name and number, your name, and then copy and paste everything below beginning with “Scenario” onto your first page. The 2nd page of your document should include the description of Part 1 and then your diagram and answer. Do the same for Parts 2-5, with each part on a separate page. Scenario: The Federal Government implemented a policy some years ago to subsidize the production of ethanol fuel at 46 cents per gallon. See news article here: http://usnews.nbcnews.com/_news/2011/12/29/9804028-6-billion-a-year-ethanol-subsidy-dies-but-wait-theres-more?lite Ethanol is an alternative fuel (a substitute for regular gasoline) that can be used in some models of automobiles designed to burn any mix of gasoline up to 85% ethanol (fuel is known as E85, and auto manufacturers label these vehicles as “FlexFuel” and similar names). A primary input in the production of ethanol is corn. For the purposes of this assignment, assume that all relevant markets are perfectly competitive. Part 1: Show geometrically using the supply and demand curves the impact the subsidy had in the ethanol market (hint: the result has been a reduction in the market price of ethanol). Fully explain the impact of the production subsidy in terms of the behavior of producers (sellers) in the market and customers (buyers) in the market and what has happened to equilibrium price and quantity in the market for ethanol. Part 2: Show geometrically using the supply and demand curves what impact the reduction in market price for ethanol had in the market for regular gasoline. Fully explain the impact this reduced ethanol price had on the customer demand for regular gasoline. Part 3: Show geometrically using the supply and demand curves the impact due to the change in the equilibrium quantity in the market for ethanol had in the market for corn. Fully explain the impact and the resulting equilibrium price and quantity for corn. Part 4: Show geometrically using the supply and demand curves what impact the change in the market price of corn had in the market for manufactured corn tortillas (assume that the market for corn tortillas is perfectly competitive). Corn tortillas are a staple food item in the diets of millions of families across the U.S.. Fully explain the impact of change in the market price of corn in terms of the behavior of producers (sellers) in the market and customers (buyers) in the corn tortilla market. Part 5: Show geometrically using the supply and demand curves the impact in the ethanol market when the ethanol subsidy ended on Jan. 1, 2012. Give one possible explanation why I can no longer find E85 fuel at gas stations. Hint: When the subsidy still existed, the market price of E85 was about 30 cents a gallon less than regular gasoline. E85 is not a perfect substitute for regular gasoline because the performance is less and gas mileage drops by 5-7 miles per gallon.

Aims The aim of this module is to: • Develop individuals for a career in business and management • Enhance and develop employability , professional and lifelong learning skills and personal development Learning Outcomes Learners will be able to critically evaluate the acquisition of a range of academic and professional skills using a number of theoretical frameworks. Assessment – Summary Category Assessment Description Duration Word Count Weight (%) Written Assignment Essay 1 Reflective Essay N/A 3000 45 For full details, go to Assessment. Additional Information Remember that a variety of Resources is available to support your learning materials.Skills and character audit This document provides an initial picture of your skills and character. It will also provide the basis of further documents that make up the first assignment on the module. It is based on the skills statements that form a fundamental part of your Masters programme which were approved by a validation panel that consisted of members of staff in the Business School, academic staff from other higher education institutions and employers. The statements in the form are there for you and you will not be judged on whether your responses are positive or negative. The responses should enable you to identify what you are good or bad at from which you can create a personal SLOT analysis (Strengths, Limitations, Opportunities, Threats). From this SLOT analysis you can then concentrate on developing certain areas that will enhance your academic and professional development. We would very much like to” get to know” you through this document and would encourage you to also complete the notes section. In this you could give us a rationale for your responses to the questions. As a guide to how you should gauge your response consider the following: Strongly agree – I have a wide range of experience in this area and have been commended by a tutor or employer for my efforts in this area Agree – I am comfortable with this aspect and have been able to demonstrate my ability Disagree – I am Ok with this but realise that I do need to improve Strongly disagree – I know I am weak in this area and need to focus on this as I could fine this weakness to be detrimental to my progression Explain why – please take the room to consider the reasons for your answer as this is the reflection that is of most value. Do not worry if your section spills onto the next page.   Intellectual (thinking) skills Strongly Agree Agree Disagree Strongly Disagree I am a creative person who can adapt my thinking to circumstances I am able to organise my thoughts, analyse, synthesise and critically appraise situations I can identify assumptions, evaluate statements in terms of evidence, detect false logic or reasoning, identify implicit values, define terms adequately and generalise appropriately Explain why: Professional/Vocational skills Strongly Agree Agree Disagree Strongly Disagree I use a wide range of techniques in approaching and solving problems. I am comfortable with a range of research techniques I am able to analyse and interpret quantitative data I am able to analyse and interpret qualitative data My leadership skills are well developed and I can adapt them to different situations I am able to manage people effectively Motivating myself and others comes easy to me I am aware of my responsibilities to myself, the organisation and other people I treat people with respect and consideration Explain why:   Key/Common skills Strongly Agree Agree Disagree Strongly Disagree I am able to use mathematical techniques to analyse data I can effectively interpret numerical data including tables and charts I am able to use a wide range of software on a PC I use a range Information Technology devices to communicate and access information I am a good listener I am able to communicate my ideas well in a face-to-face situation I can adapt my written style to suit an audiences needs I am comfortable presenting my ideas to an audience Whenever I have completed a task I always reflect on the experience with a view to seeking continuous improvement I manage my time effectively I am always prompt when asked to complete a task I am aware of the need to be sensitive to the cultural differences to which I have been exposed I am keen to learn about other people and their country and culture I enjoy working with others to complete a task I know my own character and am sensitive of this in a group situation I understand that a group is made of individuals and I am sensitive to the needs and preferences of others I will always ensure that I get my views across in a meeting I am willing to accept the viewpoint of others I always give 100% in a group task Explain why: SLOT Analysis Having responded to the statements above you should now be in a position to look forward and recognise those areas on which your development will be based. The SLOT analysis can help you to arrange this. Strengths – can be those skills and characteristics to which you have responded positively to in the previous section. It is worth noting that whilst you may be strong in these areas that does not mean you ignore their development. Indeed you may be able to utilise these strengths in the development of areas identified as weaknesses or to overcome strengths, this will enhance those skills and characteristics. Limitations – All of us can identify some sort of limitation to our skills. None of us should be afraid of doing this as this is the first stage on the improvement and development of these weaknesses. Opportunities – These arise or can be created. When thinking of this look ahead at opportunities that will arise in a professional, academic or social context within which your development can take place. Threats – Many threats from your development can come from within – your own characteristics e.g. poor time management can lead to missing deadlines. However we could equally identify a busy lifestyle as a threat to our development. Once again think widely in terms of where the threat will come from. Do not worry if you find that a strength can also be a limitation. This is often true as a characteristic you have may be strength in one situation but a limitation in another. E.g. you may be an assertive person, which is positive, but this could be negative in a group situation. Please try and elaborate this in the notes section at the foot of the table. SLOT Analysis (you may need to use two pages to set out this analysis) Strengths Limitations Opportunities Threats Analysis of the Bullet points in the SLOT table Objectives Having undertaken some analysis of your skills and characteristics the aim of this next section is to identify various aspects of your development during the course of this module, other modules on your course, and extra-curricular activities. Make sure the objectives are SMART:- S – Specific. Clearly identified from the exercises undertaken M – Measurable. The outcomes can be easily demonstrated (to yourself, and where possible others) A – Achievable. They can be done given the opportunities available to you R – Relevant. They form part of your development either on this award, in your employability prospects or in your current job role T – Timebound. They can be achieved within a given timescale Whilst there are 5 rows in the table below, please feel free to add more. However be sure that you need to do this development and that they fit within the scope of the above criteria. Area What I am going to do. How I am going to do it When I am going to do it by Force Field Analysis This technique was designed by Kurt Lewin (1947 and 1953). In the business world it is used for decision making, looking at forces that need to be considered when implementing change – it can be said to be a specialised method of weighing up the pros and cons of a decision. Having looked at your personal strengths and weaknesses we would like you to use this technique to become aware of those factors that will help/hinder, give you motivation for or may act against, your personal development. Whilst you could do this for each of your objectives we want you to think in terms of where you would like to be at the end of your Masters programme. In the central pillar, put in a statement of where you want to be at the end of the course. Then in the arrows either side look at those factors/forces that may work in your favour.

1 BACKGROUND The new generation of enhanced mid core PICs such as the 16F1847 and the 12F1840 have an inbuilt temperature sensor. This sensor consists of a current source which flows through four diodes in series and the voltage drop across the diodes which is proportional to temperature can be measured by internally connecting the sensor to the ADC and determining the temperature based on the ADC value In this assignment the temperature sensor is used to create a simple thermometer application and to create an alarm should the sensor go outside the set value. Assignment Details 1) Determine the register settings needed to switch the sensor on and connect the temperature sensor to the ADC. Using appropriate values for Vref+ and Vref- display the ADC count value on the 7 segment display. 2) With reference to Microchip Application Note AN1333, “Use and Calibration of the Internal Temperature Indicator” (DS01333) determine an appropriate algorithm to convert from the ADC value to the temperature in degrees centigrade and implement it using a lookup table or otherwise. Display this value on the 7 segment display. Additional marks will be given for accuracy, calibration and averaging the temperature readings to give a more accurate, and a more stable temperature reading. . 2 In order to meet the specification the following will be required. i) Selection of appropriate microcontroller to meet the requirement of the task. ii) Development of an assembly language program to control the operation of the embedded system. iii) Thorough testing to ensure correct operation of the system. iv) Produce a project report to evidence all of the above. Follow Report Requirements (20 pages max) 1) Introduction – Clearly state the scope and aims and objectives of the project: Include Aims and Objectives, i.e. break down the project into smaller attainable aims and objectives for example one objective could be to develop a program to control the LED display. If all objectives are met then the overall project should have been completed. 2) Theory – Include any relevant theory 3) Procedure, Results Discussion – The report should show a methodical, systematic design approach. The microcontroller kits in the laboratory can be used as the hardware platform, however circuit diagrams should be included in the report and explanations of operation is expected. 4) Include flowcharts and detailed explanations of software development. Include appropriate simulation screen shots. Show and discuss results e.g. ADC program, LED program, etc. Include final/complete program. Were results as expected, do they compare favourably with simulated results, what could be done to improve the operation and accuracy of the system? 5) Conclusion – Reflect back on the original aims and objectives.

Please write clearly, show all work in an organized fashion, and circle answers. 1) Using the data shown in Figures 6.14 (at 25oC) and 6.21, combine both curves onto one plot, being careful to correctly plot the modulus, yield strength, tensile (ultimate) strength, and ductility. Discuss how the modulus, yield strength, and ductility compare for pure iron (figure 6.14) vs. the alloy steel. 2) The equation for the effect of grain size on yield strength is given by: y = I +kD-0.5 where y is the yield stress, I is the intrinsic resistance of the lattice to dislocation motion, k is the “blocking parameter” which measures the effectiveness of grain boundaries in blocking dislocation motion, and D is the grain diameter. Use this equation to determine the change in yield strength of a typical steel when the grain size is increased from 10micron to 50 micron (1 micron = 10-6 m), due to grain growth. . I = 150 MN/m2 and k = 0.70 MN/m1.5 . 3) Using the data shown in Callister Figure 7.19, draw an approximate stress-strain curve for the 1040 steel at 0% cold work and at 30% cold work, clearly indicating the yield strength, ductility, and tensile strength of the steel before and after cold-working (Young’s modulus of steel E = 250 MPa). 4) A fatigue test is carried out on a steel having an ultimate strength of 289 MPa. The number of cycles required to break the specimen at different stresses are given below: Stress Amplitude Fatigue Life (MPa) (cycles) 223 4.5 x 104 209 2.4 x 105 192 8.0 x 105 178 1.5 x 106 175 2.7 x 106 168 7.8 x 106 168 >1.0 x 107 (did not break) 165 >2.6 x 107 162 >2.2 x 107 a) Plot the data on linear-log scale, preferably with a computerized figure-plotting program. b) Determine the average fatigue strength at 106 cycles (hint: use curve-fitting software to fit the line). c) What is the ratio of the fatigue strength at 106 cycles to the ultimate strength? e) If you plan to use this material for 108 cycles, what is the maximum fatigue strength you would recommend (assuming 20% fluctuations in stress amplitude). Callister Homework Problems: 7.22, 8.4, 8.12 (see next page)
