Long Written Task
Order Description
For this writing assignment you are asked to choose a specific research field within the humanities and provide a history of the discipline including, in particular, the means by which it both distinguished itself from and entails other fields.

I wanna let you know that my discipline is Linguistics, specifically, PRAGMATICS, my interests in Speech Act.

Note: I’d like you firstly to decide what will be the topic and what are you going to discuss in this paper in order for me to confirm that topic with the course coordinator. it has to be confirmed by the course coordinator before start writing, please.

Article Review for Capital Structure Policy

Topic: Article Review for Capital Structure Policy

Paper details:

You are asked to summarize a journal article in the areas of capital structure policy in your words along with some critiques on it.

Please do not just write what the article is about. Your summary and critique should be a thoughtful discussion of the article.

The length of double spaced 3-5 pages (12 point -Times New Roman font) would be desirable. Your paper must have separate sections for the “critiques” and your idea about a possible “follow-up research” in addition to the sections of the “summary.”

The sections of the summary include: (1) research motive or questions of the article (2) brief survey of the previous literature (3) main results and their economic interpretations. The section (s) of the critiques contain your critiques (the more is the better, but, it should be more than half page).
Your assignment will be graded based on the following criteria:

Overall Quality & Organization

Completeness of Written Summary

Critiques & Research Idea

Depth of Understanding of the main issues discussed in the article

They should be at least 1.5 pages (no more than 4 please unless you are strongly considering a theme for the final Research Paper)

Topic: Writer choice

Paper details:

Reaction Paper Reaction papers are due every couple of weeks. They should be at least 1.5 pages (no more than 4 please unless you are strongly considering a theme for the final Research Paper). The purpose of the reaction paper is so that I know you are either engaging in the text or the class discussion (or both). These help me understand how much you are learning and how your critical thinking skills are developing as you engage in this foreign curriculum. If you have problems meeting the minimum length, consider addressing multiple topics. I have structured the Reaction Paper due dates so that they conform to general themes in Philosophy. These are due on Wedsnedays noted in the schedule. Title of Paper is Centered

1. Double click the area above that is greyed-out and put correct information (Name and Date). PHIL 1301-CF is just so we know which class and campus the class is for. Leave my last name.

2. Title should indicate the theme of your paper and be centered. You can also include Reaction Paper1/2/3/etc. in it, if you want. Ex: “Reaction Paper 1: The Presocratics’ Theories of Reality”, or just “The Presocratics’ Theories of Reality”.

3. All text should be 11 pt Times New Roman font.

4. Margins should be 1” on all sides.

5. If you are quoting text that someone else has written, and it is takes less than 4 lines, put quotation marks around it. If it is 4 lines or more, then put it in block quotes: Start on new line, NOT indented. Type it all out. Then highlight and press “tab” twice. If it is obvious where you got it from, simply cite page numbers. If it is not, then put author’s name and page number.

6. If you cite anything other than the textbook, you must include proper bibliography citation. Look at https://owl.english.purdue.edu/owl/ . Please use MLA formatting.

7. General Structure should be: a. 1st paragraph grabs attention and states primary focus of paper. b. 2nd paragraph should elaborate on the problem and outline the structure of the paper. “The fundamental element of the universe was an important aspect of debate. The theories varied wildly among Thales, Anaximander, Anaximenes, and Pythagoras.” In this example, your next paragraph would outline Thales’ argument. The next would outline Anaximander’s , the next would outline Anaximenes, and the one after would cover Pythagoras’ theories.

8. After the body of your essay is done, you can add a paragraph identifying which theory or aspect of a theory you found intriguing (and why), or identify possible problems with theories.

9. Your last paragraph should summarize the whole paper.

Rough Rubric: On time = 1 point. -.25 points every day late (unless you discuss it with me). Properly cited and formatted = 1 point. Blatant plagiarism will result in a 0. Proper grammar and spelling = 1 point. Except for a typo or two, it’s important to write properly. Content = 2 points.

The point of the assignment is to engage in the material and practice philosophical comprehension and analysis. Total is 5 points. This reflects the portion each paper is worth towards final grade.

First Order: Financial Forecasting Paper (with eviews 8 or 9)

You will find all relevant infos in the prepared folders. I would like to get a progressive delivery option, with a short feedback about the project ASAP and then a first draw on Saturday. (after that all 3 days) Target mark 80% and more. For the financial forecasting paper you will have to download the date from the oecd site and choose one additional country.. please take Switzerland (or UK) if possible and on the first step where you have to replicate the results.. logically the results have to be the same as on the paper.. so you can check if it is right done| the needed paper for the financial forecasting is online you can just google for it. Please read all instructions before beginning and follow the steps we did in the tutorial (see PDFs). Please use next to the main paper also the other provided papers as sources. Thank you

Further infos:
Please follow the given steps in the uploaded slides, explain the used models (garch, arch and and and). It is primary an econometric paper, where is has to be clear what has been calculated. And include the uploaded sources. Thank you

I uploaded the assessment criteria for a former econometric paper and the paper itself (83% paper). The calculations are completely different. But it’s just to see a little but which criteria were important. (Can be used for the financial forecasting project)

Here some basic stuff, which has to be included in the modelling process: AR Modelling ARMA Modelling Box-Jenkins approach, Unit root test, Cointegration-EG test, Cointegration-Johansen test, Arch and Garch Engle-Granger procedure

It is very basic that all this procedures and test are done for the modelling as otherwise the paper will fail for sure. If you are not sure how to calculate or proceed for something of the mentioned points, please follow the step-by-step instructions, which you will find in the sub-file “Practicals and Approach”.

As I want to be sure, that this time everything will work as supposed, I uploaded the following documents you can use: – The layout for the Financial Forecasting Workpaper. Please use this layouts for the paper, (you can change the titles and subtitles as you want) .

and further infos, I forgot:

Perhaps a little further input to the OECD data for the forecasting.. After the download you need to index them(1980:1), this means divide all data for that number in each country. But pretty sure you figured that already out. For the rest if something is not clear, please contact me and I will try to figure out what’s the needed next step. Thank you

if you follow the seminars with the different models and procedures, given the fact, that we already know how to begin and the main steps (stationary testing, detrending..) it should be still feasible on a high level.

I figured out, that for beginning the paper you need to use the perron sequental procedure… please control that you began with it. And after that control if it is a deterministic trend or a random walk, before you can continue with the detrending.

2. A photo detector counts photons for 10 nano seconds to decide if a distant light source is
emitting light. When the light source is not emitting light, some photons are still counted by
the detector due to the ambient background radiation. The number of photons counted in 10
nanoseconds is modeled as a random variable X whose parameter ? has value ln(9) if the
light source is not emitting light, and value ln(27) if the source is emitting light. The
maximum-likelihood detector decides that detection of light is the true if and only if the
likelihood ratio = probability of detection when light is present (x)/probability of detection
when light is not present (x) exceeds 1. (a) What value(s) of X result in a decision in favor
of detecting of light? (b) Compute the false alarm probability PFA and the missed detection
or false dismissal probability PMD of the maximum-likelihood decision rule.

3. 100 AIDS patients were given a new drug test. The results were as follows:
Year on drug Number of deaths Number of withdrawals
1 5 2
2 8 4
3 12 2
4 18 10
5 24 12

Withdrawals occurred when patients left the test area or died from causes not related to the
AIDS disease. Construct a life table to estimate the probability (reliability) that a patient
will survive at least five years.

4. Determine the minimum-cost trade-off between the MTBF and the MTTR for a system
requiring 0.99 availability. The MTTR must be between 10 and 30 hr, and the MTBF must
be at least 1000 hr. Consider the cost functions as:
a. C(x) = 0.0002x
2
; C(y) = 12500/y
b. C(x) = 2x; C(y) = 2000-y

5. The Breakit Company manufactures anti-clock disk brakes (ABS) for use in automobiles.
An essential part of the manufacturing process is the factory assemble and integration
linking (FAIL) system. Unfortunately, this system has experienced numerous failures over
the years under minimal repair concept that is a non-homogeneous Poisson process having
an intensity function ?(t)=1.15×10

with t measured in operating hours. The system
averages 2000 operating hours a year and it currently 5 years old. When the system fails,
the repair time is lognormal with tmed = 6.2 hours and s = 1.2.
a. When the system was new, its manufacturer offered a 500-operating-hr warranty.
What is the system reliability during the warranty period?
b. When the system fails, it takes a crew of two to repair it. If the labor rate is $50 per
hour and based upon the MTTR, what is the maintenance cost of the FAIL system
during its 6
th
year of operation?
c. If the cost of the system is $30,000, what is its optimal (minimum cost) replacement
time?
d. Management believes that a preventive maintenance (PM) program may be cost
effective. A PM consists primarily of replacing certain parts having a cost of $700
and thus restoring it to as-good-as-new condition. If it takes one technician 4 hours
to do this, what is the optimum (minimum cost) PM interval?

6. External corrosion is a potential failure mechanism of buried natural gas pipeline. Once the
protective coating and/or the cathodic protection system fail the external corrosion rate
depends largely on the characteristics of the surrounding soil. The corrosion rate is
typically modeled using an empirical power-law relationship as: ? = ??
!
where y is the
corrosion depth, t is the exposure time, and A and n are site dependent constants, with n
typically less than 1. Below is the data available from a specific site. Estimate the failure
probability of 40 mm pipeline in 20 years. Pipeline failure may be defined as loss of 66%
of the pipeline thickness.

Time (years) Corrosion depth (mm)
0 0
1.5 2.5
3.5 5.0
5.0 8.5
8.5 11.0
12.0 13.5
15 14.0
17 14.5
19 15.0
7. An offshore platform consists of three large main power generators (MPGs), two operating
and one spare (standby mode). The lifetime of each MPG follows the Weibull distribution
with beta = 2.3 and theta = 40 years. In a given time, two MPGs are used, while third one
can be used to replace a failed unit in 12 days with a cost of $ 5 million. The failure of each
additional unit requires the procurement and installation of a brand new transformer with a
cost of $ 280 million. Estimate failure probability and associated risk with the MPGs over
the next 20 years of operation considering both scenarios (spare is available as good as new
and spare is in failed state).
8. The load (S) and resistance (R) are modeled as log normally distributed random variables
with the following parameters: the mean and coefficient of variation (CoV) of the load are
160 kN and 0.15, respectively, while the CoV of resistance is given as 0.28. a) If the
design criterion is R = S, then what should be the mean resistance? Assume the nominal
resistance (R) is the 5th percentile of the distribution; b) what is the probability of failure
for design criterion R = S?; and c) what is reliability index?
9. A repairable system consists of three non-identical components A, B and C, all of which
must work for system success. When one component fails, no further component failures
can occur. Construct the relevant state space diagram and hence evaluate general
expressions for the individual limiting state probabilities in terms of component failure and
repair rates. Evaluate the unavailability of the system in hour/year if the three components
have the following reliability data.
Component Mean time to Failure (yr) MTTR (hours)
A 1.0 180
B 2.0 12
C 1.0 52
10. The figure below shows the pipe layout in a lawn sprinkler system. Sprayers are located at
every intersection of the pipe and also at the corners of the system. Thus there are 16
sprayers. Two things can happen to a sprayer: it can break off or it can get clogged. If any
one of the sprayers breaks off, a great stream of water will pour forth and the system will
have failed. If one of the sprayers clogs, it will fail to water the lawn in the immediate
vicinity; however, adjacent sprayers can reach the affected areas. The system is judged to
4
be failed if any two adjacent sprayers are both failed. For one sprayer, let the probability of
breakage be 0.01 and the probability of clogging be 0.05. Find the reliability of the system
(the probability that it does not fail in either mode).

Layout of the sprinkler system
11. A gas-fired furnace is shown below. The hot combustion gases pass through heat
exchanger to heat fresh air for space heating. The gas flow is controlled by an electric
solenoid valve connected to a thermoset. The gas is ignited by a pilot light flame. A hightemperature
switch shuts off all gas in the event of high temperature in the fresh air.
Develop fault tree using step-by-step approach for an event (scenario) “No Space Heating”.
