Advantages And Disadvantages Of Density Forecasts

Advantages And Disadvantages Of Density Forecasts
The density forecast of a random variable is an estimation based on the past observed data. This is a
symmetric interval prediction which means that the outcomes will fall into an interval that is a band
of plus/minus a fixed times of standard errors. The estimation provides a probability distribution of
all possible future values of that variable. Over the past decades, the price density forecast has been
widely used to study microeconomic and financial issues. Forecasting the future development of the
economy is of great importance for proper government monetary decisions and individual risk
management. A good macroeconomic density forecast presents a subjective description of
inflationary pressure and other information related to economics. ... Show more content on

Example Of Personal Narrative Essay
For most of my life, I've really struggled with math. My first memory of math and insecurity was in
third grade, when we started doing timed multiplication. I could always feel how cold the seat
suddenly seemed to be, and I could never finish the whole sheet. None of the other kids could either,
but I couldn't shake the feeling that if I was really smart, I'd be able to. I used to come home and cry
to my mom every day we had tests like that. Both of my parents are computer programmers, and my
sister showed a mathematical aptitude as soon as she was in school. I compared myself to my older
sister and parents, and felt so ashamed every time I failed. Over time, even though I kept pace with
the kids in my classes, I felt increasingly inadequate. ... Show more content on Helpwriting.net ...
They understood that the struggle was part of the process, and so they had a tolerance for it that I
hadn't had before. I began to understand the willingness to struggle for the sake of knowing more. It
was terrifying at first, but after that I started to ask the teacher questions, and to be proud of myself
when I got a new principle, no matter how long it took me, or how many times I had to have
examples worked on the board. I still felt the old frustration and insecurity often, it was built up over
years of my life, but I reinforced my commitment to learning every time my patience with myself
resulted in deeper understanding, and especially every time I could help someone else. My struggle
with math made me develop diligence that wasn't from beating myself up, and a tolerance for failure
that I use in all aspects of life. It also showed me that having humility around my struggles made it
safer for my friends to ask me for help. It's still not my strongest subject, but outside of the
coursework I feel like I've learned more from my failure in math than my success in any other

The Importance And Benefits Of Math Manipulatives In...
 Boggan (2010) explained the importance and benefits of math manipulatives. The value of
manipulatives has been recognized for many years, but some teachers are unwilling to use them in
teaching. Elementary teachers who use manipulatives to teach mathematics can positively affect
student learning. Students at all levels and of all abilities can benefit from manipulatives.  Bradley
et.al. (2008) examined teacher's attempt to improve instructional strategies for teaching mathematics
in an elementary school. The findings of the study revealed that the students were more involved in
math activities, especially during peer tutoring. The students enjoyed the music as well as the
entertaining videocassette with the mathematics objective as the subject of a story. Perhaps as a
result of the audio, visual, and kinesthetic modes of instruction, students actually appeared more
attentive during direct instruction. Teachers reported that carrying through with manipulatives and
number lines with the fourth–and–fifth graders helped them to grasp abstract concepts and become
more accurate in solving problems in the math textbook.  Kelly (2006) explored in elementary
classrooms that how children use manipulatives and/or tools in problem solving while working on
mathematical tasks. Current research reveals that teachers need to teach and assess children's
mathematical knowledge in ways that will allow them to show (perform) what they really
understand. In this research use of

The addition is the first operation children learn from a young age and mastering it, is the first step
toward the long–lasting appreciation of maths. Children from Early Years Foundation Stage (EYFS)
do not need to memorise complex additions in order to become confident with basic addition.
instead, teachers support children to practice counting; counting on, doubling, learning place value

However, with subtraction calculations, this is not possible. Hence they are expected to 'use inverse
relationship between addition and subtraction to check calculations and solve missing number
problems.' (NC, 2013).
One of the approaches, which is highly recommended for children to practise, is to do addition
calculations mentally (working out calculations in their head) using various strategies, which is the
focus of this essay. Tony Cotton (2013, p.109) states that developing mental approaches is more
efficient to work out solutions to problems and helps children to become fluent in mental
calculation. However, doing mental calculations, such as addition, can be challenging and confusing
for some children. Therefore, introducing appropriate strategies (for example counting on,
partitioning, bridging through 10) and using them to draw images or mark–making will encourage
children to 'see' calculations in their heads and will allow them to use the strategy which is the most
suited for them (Cotton, 2013, p. 110).
Ian Thomson also suggests (I part 1 addition) that visual representation plays an important role in
developing mental addition. for example, number lines help children to recognise place value and
with prior knowledge of ordinal sense of numbers, it helps them to move from counting in ones to
counting in larger steps, such as 2, 5, 10, 100 and so

Final Reflection
Math is a subject that I have struggled with for a very long time; it is something that I always set
aside. Math is something that I never saw myself using in my future and I thought if I put it off it
would just disappear. When I came to the University I had to take Math 100 and Math SAX, which,
unfortunately set me back on finishing math quite a bit because I did not put in the effort as much as
I should have, and the amount of work they gave, was quite an overload. I took those courses twice
and was still not put into a Math course at the University. That is when I started to push math away,
but I have realized I cannot put it off and math is definitely important and we do need to know the
subject no matter where we go in life or regardless ... Show more content on Helpwriting.net ...
After my second year at the University I had taken a semester off in the fall of 2015 and returned in
the following spring semester of 2016. During my time off I realized that school is extremely
important and is something that needs to be done. When I returned in spring, I turned my grades
around I worked really hard to show that I am ready to be apart of the School of Journalism. I was
able to bring my grade point average up and I received grades that I worked very hard to get. During
the spring semester I still had in mind that I need to finish math in order to get into the School of
Journalism. This summer at Pima Community College I have taken the math course 122 and passed
the course; however, I still need to take the required math course 142 to be apart of the School of
Journalism. I worked very hard in math 122 and I plan on doing that for math 142 and all my future
courses. I unfortunately was not able to get into the course for the second session of summer but
would like to take the math course at Pima Community College along with the journalism courses at
the University. I am eager to take the math course and pass it, along with the journalism courses. I
am extremely proud of how well I did during the spring and I am determined and motivated to do
just as well if not better during the this fall

Investigation Of Turkish Students ' Mathematics...
Investigation of Turkish Students' Mathematics Performance based on PISA 2012 Objective The
purpose of this study was to investigate the relationship between selected student– and school–level
variables and mathematics performance of Turkish students using PISA 2012 dataset. Two research
questions were investigated: (1) How much do schools vary in their mean mathematics achievement
in Turkey? (2) Which student– and school–level variables are associated with students' mathematics
performance in Turkey based on PISA 2012 results? Theoretical Framework PISA is a 3–year cycle
of international assessment, which has been organized by Organization for Economic Co–operation
and Development (OECD) since 2000. The primary aim of the PISA assessments is to determine the
extent to which young people, who are 15–years old, have acquired the wider knowledge and skills
that they will need in their real–life challenges with considering a literacy perspective in reading,
mathematics, and science. According to PISA 2012 overall results, Turkey ranked 44th, 42nd, and
43rd positions across the 65 countries in mathematics, reading and science, respectively (OECD,
2014b). In this present study, some student– and school variables were chosen to determine if there
is any effect on students' mathematics performance in Turkey. Gender is the first variable coming to
mind when someone starts an educational research because there are not any certain statements;
therefore, the influences of gender on the

Case Study: Application of Real Options to Energy Investments
Introduction
Energy investments have been evaluated using diverse methods. Santos et. al. (2014) argue that
conventional approaches such as Net Present Value (NPV) or Internal Rate of Return (IRR) do not
consider relevant project characteristics like irreversibility, uncertainty and management flexibility.
They propose that the Real Options Approach (ROA) has an advantage over conventional methods.
The aim of this essay is to apply real options to a renewable energy investment (mini–hydro plant)
using the binomial lattice tree developed by Cox, Ross and Rubinstein.

Despite this distinction, most principles of financial options are applied to real options. The table
below depicts the relationship between these concepts.
Table 2: Financial and Real Options Source: Sanislo (2002)
There are various types of real options. For this essay the deferral option is used; a deferral option
gives its holder the option to begin an investment immediately or at a future date. The Black–
Scholes formula for pricing options and the binomial lattice model are the basic financial models.
The Black–Scholes Model and Multiplicative Binomial Option Pricing Model
The Black–Scholes formula for valuing options was the first numeric formula for pricing European
call options. Santos et. al., (2014) argue that Fisher Black and Myron Scholes's formula is rooted in
Modigliani and Miller's non–arbitrage proposition. The model holds the following assumptions: a)
the risk–free rate is known and constant over time; b) the asset pays no dividends; c) the option can
only be exercised at its maturity date; d) there are no transaction cost when buying or selling an
asset or its derivate; e) it is possible to invest any fraction of assets or derivate to the risk free
interest rate; f) there are no penalties when selling short; g) the model is developed from the concept
that the option asset price has a continuous stochastic behaviour,

Why Math Is Wrong
When your parent is an ex–math teacher and you are terrible at their subject, you are doomed. My
mother was a middle school math teacher when she lived in India. So, because of that, I have had
math drilled into me from a young age and I resented it. Math never came to me easily. I would
spend hours on a topic I did not understand because nothing got through my thick skull. Those hours
consisted of my mom breathing down my neck and passive aggressively "yelling" at me to get the
right answer. I cannot pin down what factors caused me to have difficulty in math. My mom likes to
say I just seem to take more after my dad rather than her in math (he is not that great in it). I,on the
other hand, think it is because I was scared of being wrong.

Strengths Of The Black-Scholes: Option Pricing Model
In 1973, Fischer Black and Myron Scholes developed the option pricing model called Black–
Scholes option pricing model. The model explains how to calculate the price of the option by using
present value of the asset's price, volatility, strike price, time to maturity, and the risk free interest
rate existed in the market. Time to maturity is usually expressed as the number of days. The Black–
Scholes option–pricing model can use for European call option, which pays no dividends at zero–
coupon risk–free interest rate before the option expire.
Majority of the market participants use the model for many reasons. Therefore, this paper will be
carefully studies the model with detailed analysis of the strength and weakness based on the
assumption of ... Show more content on Helpwriting.net ...
The inputs are more objective than other option pricing models.
The main strength of the model is its simplicity as other variables are easy to get from market. Once
the five variables are collected, the value of the option can be calculated easily. Therefore, this give
a benefit to market participants since they can compare market prices with different values based on
different inputs.
Although the model might seem as a complicated model for human calculation, the formula is
simple in mathematical terms. Therefore, high–tech computer programs are not need to compute and
it can also save time.
One of advantages of the model is that investors can use the model to analyze market volatility of
underlying assets. Results from the model are often useful in practice and minimize risk even
thought volatility is not constant. Then, investors will know whether the market value is rewarding
investment or not. Therefore, it acts as insurance and helps to reduce possible loss and expand
profits. Black–Scholes model is not only useful for estimating the value of the call option and
hedging of option but also enlarge the approach to other derivative

Arundel Partners: the Sequel Project
Arundel Partners: The Sequel Project
The maximum per–film price for the sequel rights that Arundel Partners should pay is $5.12M.
If Arundel Partners were to use the traditional DCF methods to find the value of the sequel rights,
the NPV would be –$8.42M loss per–film (see Appendix 1).
Calculation Details
We assume that Arundel Partners will purchase a portfolio of films similar to one used in the
analysis. The average hypothetical net inflow of the sequel ($21.57M) is used to figure out the value
of the state variable for the real options model. The state variable is the average hypothetical net
inflow of the sequel, discounted using a WACC of 12.36% back to 1989. Discounting back to 1989
is important because this is ... Show more content on Helpwriting.net ...
Building the Binomial Tree for Asset Values
The binomial model is used to see how the state variable evolves over time, specifically over a time
period of 12 months (see Exhibit 1). The maturity or expiration date of the sequel rights option is set
for 12 months. Within the first year, Arundel Partners will know whether it will want to exercise the
sequel rights. We build the binomial tree for the net inflow values using the Cox–Ingersoll–Ross
model. This approach approximates a lognormal distribution for the asset values (net inflow values).
We assume that continuously compounded returns on the asset are normally distributed and
volatility remains constant. We use the expiration date as one year from the purchase of the sequel
rights and the time interval of 1/12 (1 month). We use the standard deviation on the one year return
of the portfolio as an estimate

Sheila Tobias Overcoming Anxiety
Overcoming Math Anxiety by Sheila Tobias, 1995, lays out the groundwork for addressing math

and most importantly, how to start working on overcoming it. A strong theme that continues
throughout the book is the issue of gender differences in relation to math anxiety and why from
Tobias's findings and opinion is either true or false. However, the message throughout the book is
clear. While math anxiety is a real issue that many suffer from, because of the everyday use of math
and the benefits of being competent at using it, we are limiting ourselves by avoiding the subject
like the plague and therefore must find ways to move past the anxiety. The book starts its first three

the average person has a non mathematical mind" (CITE), and that in the end defining someone

is the heart of math anxiety, will be different. However, what is important is learning how people
each solve them which requires them to self–reflect on themselves as learners which is very useful
in math and in general life. Tobias emphasises the importance of being able to do everyday math. In
this chapter she helps us relearn useful ____ such as fractions, statistics, remodeling terms such as
minus, in a broad manner that is meant to be used as a tool to fully relearn math on your own. ––––

In the last years, distribution automation has gathered a significant relevance in distribution systems
planning and operation. The network operator (NOp) looks for a suitable configuration of the feeder
topology as well as the system, pursuing the reliability enhancement and a full energy demand
supply. Nevertheless, an efficient protection system requires an adequate investment in such devices
as reclosers, fuses and sectionalizers. Thus, two conflictive objectives arise, namely, NOp
investment minimization and reliability maximization.
In this sense, the number and location of devices in the system are critical variables to accomplish
preceding objectives. Here, we focus on recloser–based protection systems.

Hence, it is necessary to apply metaheuristic approaches.
The remainder of this paper is organized as follows. In section II efficient planning of NCRs by
applying a multiobjective optimization approach is described. The optimization problem
formulation is presented in Section III, along with objective functions details. Section IV presents
the MOEAs to solve the multiobjective optimization problem. Here, the revised non–dominated
sorting genetic algorithm (NSGA–II), and non–dominated sorting differential evolution (NSDE) are
detailed. The test system is given in section V, and simulation results are provided in section VI.
Finally, conclusions are drawn and future research is suggested.
II. MULTIOBJECTIVE OPTIMIZATION APPROACH
In most real world optimization problems the solution must to be found considering multiple
objectives instead of one.
Whereas these objectives are often in conflict, a trade–off relation among them arises. that is, it is
necessary to sacrifice the performance of one or more objectives to enhance the other ones. Let us
consider, in the context of this paper, the decisionmaking involved in the sizing of the protection
system and the placement of NCRs. The amount of protective devices in a DS can vary from any
recloser to a few. Let us take two extreme hypothetical cases: 1) non branch has the

Math Anxiety Essay
Math anxiety can affect the education of children by causing them to avoid obtaining educational
degrees beyond high school because they are afraid to enroll in college math courses. Since a
majority of well–paid jobs require college degrees, anxiety toward learning math affects future
career plans. What are the contributing factors of math anxiety in the United States in the past ten
years, especially in children and young adults? Math anxiety can be divided into two categories:
probable causes and possible solutions. I began my research with a study about math anxiety in
young adults. In the article "The Effects of Math Anxiety" (2015), Amanda Andrews and Jennifer
Brown claim that "math anxiety is a reoccurring problem for many students, and the effects of this
anxiety on college students are increasing" (362). Furthermore, the authors collected observational
data about the effects of math anxiety on college freshmen in order to determine that math anxiety
has a negative correlation with math performance. Erik Erikson, a theorist mentioned in the article,
developed the theory of industry versus inferiority, which says that "children, ages 6 to 12, either
gain competence or feel they are inferior in certain skill areas" (363). When applied to math anxiety,
the theory indicates that children either understand math or they do not. The authors discuss
correlations between math anxiety and gender, especially females (364). For example, although

Hilton ITT Case Study Essay
1. Why might Bollenbach have opened his bidding for ITT at $55 per share? What was his likely
strategy?
The $55 value is on the lower range of the analyst eztimates, with a best guess estimate of $67.94.
Since the value of the stock had been below $45 for 4 months, the offer of 55 dollars represented a
29% premium to investors. Bollenbach knew that management would be resistant of any attempt to
be acquired, regardless of price, because of failed previous attempts to negotiate a friendly merger at
year end 1996. The 55–dollar benchmark created an expectation for ITT management to achieve
that level, or higher and the premium is enough to demonstrate to investors it is a real offer. Their
support will be key as they will have a ... Show more content on Helpwriting.net ...
Bollenbach knew that the next steps would be critical or the deal to go through. As such it was
necessary to first research the investors and arbiters to have better negotiation tactics when the time
comes. The resistant board of directors had not changed in the mean time and would likely resist
any offer, including the unlikely event of another contender entering bidding. If the price of the
stock fell below the $55 range, or the Board of Directors changed Bollenback would likely
aggressively negotiate with shareholders to close the deal as quickly as possible.
3. ITT's value has changed a lot over the recent events. Prior to any offer when ITT's stock was
trading at 43 dollars, the stand–alone value of its equity was 16.4 billion dollars. With the 55–dollar
offer to ITT, the company's value went up to approximately 21 billion. After the offer, the stock was
trading at $63.50, which gave the total equity a value of 24.2 billion dollars. With the proposed
trivesture proposal, the company would lose synergistic value as three separate companies,
compared to one large company. Examples of these include a number of overhead costs which gain
economies of scale. In addition, ITT likely has synergistic revenues coming from the fact that it
operates all three business segments. Analyst estimates indicate that the present value of the
synergies whichh ITT stands to loose with the proposed trivesture have a NPV between $900 and

Fyodor Dostoevsky's Crime And Punishment
Fyodor Dostoevsky, who was considered to be a genius of his time, was spared from a death
sentence he received for his involvement in a literary group that discussed banned books. As he was
close to being killed, this experience provides an explanation for his belief that killing is unjust and
does not better society. In Dostoevsky's book Crime and Punishment, this belief is developed
through a criticism of the theories and actions of the main character Raskolnikov. Raskolnikov
believes that he has the right to kill an old pawnbroker because he views himself as extraordinary
and her as a negative member of society. Porfiry, an older, logical detective, invalidates
Raskolnikov's extraordinary man theory through his questions and his own ... Show more content on

This trait of Porfiry emphasizes Raskolnikov's lack of logic. He easily fell into Porfiry's first trap,
and he did not consider the consequences of writing an article about becoming ill from a crime and
then actually becoming ill from committing a crime. This oversight takes credibility away from
Raskolnikov because it makes him seem less sharp than before. Similarly, Raskolnikov falls for
Porfiry's second trap. This time, Porfiry misrepresents one of Raskolnikov's ideas from his article
stating "the extraordinary have the right to commit all sorts of crimes and in various ways to
transgress the law" (259). In this trap, Porfiry appeals to Raskolnikov's pride for his article to bait
him into revealing incriminating details of his theory. This tactic exemplifies Porfiry's clever logic
and characterizes him as a skilled detective. Oppositely, Raskolnikov's response characterizes him
as an easily manipulated criminal as he falls into the trap, explaining "I merely suggested that an
'extraordinary man' has the right...to allow his conscience to...step over certain obstacles, and then
only in the event that the fulfillment of his idea––sometimes perhaps salutary for the whole of
mankind––calls for it" (259). Not only does Raskolnikov reinforce that he believes the extraordinary
man can commit crimes because of

GYA is a non–profit organization that helps and aids low–income families. One way they do this is
through their job placement program where they find low–income high schools jobs for the summer.
This is in the hopes that in the long run they will be permanently hired in their assigned summer
position. During my experience in volunteering for two summers I met K, the head coordinator for
this summer program and the first weak tie in my social network. Since I had known K through
volunteering, I reached out to her about my situation. Once she heard about what my family was
going through K utilized her social capital to quickly get my younger sister and me a job. I was
grateful that it was during the summer that we received the eviction notice since GYA only places
teens in jobs during the summer. However, K found a position for me at a coffee shop that extended

K my sister and I had temporarily been hired at the location she placed us in that worked with our
school schedules. My family and I benefited tremendously from K because she had social capital
that my strong ties did not. She had been working at GYA for over 10 years, allowing her to build
relationships and network support. This allowed us to

Negative Effects Of Math Anxiety
Solving math problems is always difficult, however for some students it gives them fear and tension
that often leads to math anxiety (Maloney, Beilock, 2015). Math anxiety can begin from primary
education and if it is not lowered then it can affect the student for life. When math anxiety increases
as people grow they tend to avoid anything that is dealing with numbers. For example, they will
avoid budgeting, going over bills, and even affect the way they help their kids in math homework.
Teachers and parents play a very important role in the student's math education. Primarily, a
teachers' way of education math to students can be the reason they dislike or enjoy mathematics. If a
student develops math anxiety they will experience both physical and psychological symptoms
(Bohrod, Blazek, & Verkhovtseva). According Bohrod, Blazed, and Verkhovtseva some physical
symptoms can be nausea and sweating, some psychological symptoms can be loss of confidence and
math avoidance. Math anxiety is in everyone however it is in a lower stage of our minds and if it
increases then a student will avoid any math related problems. Math anxiety can be experience when
a student is solving math problems, during exams, and among others. Negative experiences with
math are what affect students. The main reason that students have bad experiences is because of the
way teachers taught math to them. Maloney and Beilock, explained how a teacher can cause

Classroom Environment The environment of a classroom is the tone or atmosphere of the
educational setting (Shochet & Smith, 2014). This tone is mostly set by the teacher of the
classroom, but the students also play a role in the development of the environment. Characteristics
of a positive classroom environment include organizational, instructional, and interpersonal
elements (MacSuga–Gage, Simonsen, & Briere, 2012; Shochet & Smith, 2014; Spearman & Watt,
2013). The organizational elements include all classroom management strategies and clarity of
activities and assignments in the classroom (MacSuga–Gage et al., 2012; Spearman &Watt, 2013).
Next, instructional elements include engaging and explicit instruction, support in activities,
inclusion of real world examples, and teacher feedback (MacSuga–Gage et al., 2012; Spearman
&Watt, 2013). Of these items, Spearman and Watt (2013) emphasized the inclusion of real world
examples as an intrinsic motivator for students, and the authors suggest that intrinsic motivation
increases positive self–efficacy. Gilbert, Musu–Gillette, Woolley, Karabenick, Strutchens, & Martin
(2014) also found that perception of environment increased motivation, which in turn increased
scores on standardized tests. Finally, interpersonal elements pertain to teacher–student and student–
student relationships. It is imperative that students have a perception of emotional support in the
classroom as this is related to high academic performance and social

A Research Study On Finance And Economics
Two years ago while I offered a research job at Cambridge in applied economics, one of my friends
jokingly quipped that one day I would be the next Raghuram Rajan, who had just taken over as the
Governor of the Reserve Bank of India following his academic position. I smiled as I had then not
considered the possibility of becoming an academic who could wield such power in designing
policies to govern the financial institution of the world 's largest democracy. In retrospect, this does
not seem very far from the truth with respect to my long–term career goals. I consider it a privilege
to contribute meaningful work that would improve the financial standards in my country. My
interest in a quantitative field like finance and economics comes as no surprise, since Mathematics
is one of my favorite subjects and my forte right from secondary school. The power of these
subjects to cater to practical applications in the real–world setting led to my close involvement with
them, which was also instrumental for my qualifying for the Indian National Mathematics
Olympiad. For my undergraduate studies, I chose Mechanical Engineering over the other options, at
one of the top universities for this discipline in my country, due to its significant quantitative content
and for the possibility of applying those tools to solving complex problems, which I did. The

A Research On How Social Networking
Many people worldwide are affiliated with social networks everyday. Keith Wilcox and Andrew
Stephan's did a research on how social networking, particularly Facebook, was used to boost one's
self esteem with tie strengths. Tie strength can be defined as strong or weak. Strong ties can be
described as the close connection to their friends, while weak ties are considered their
"acquaintances that are distant friends" (Wilcox & Stephan, 2013, p. 92). Wilcox is an assistant
professor at Columbia University, teaching marketing. While Stephen, "is [an] assistant professor of
business administration and Katz Fellow in marketing at the Joseph M. Katz Graduate School of
Business" (Wilcox & Stephan, 2013, p.90). The Journal of Consumer Research ... Show more

Wilcox and Stephan's hypothesis propose that the "enhanced self–esteem from browsing a social
network will momentarily lower self–control, leading people to display less self–control after
browsing a social network compared to those who did not browse a social network" (Wilcox &
Stephan, 2013, p.92). Since people care more about their image to strong ties, this effect will be on
people who are focused on strong ties while browsing the social network. Wilcox and Stephan
"expect social network use to have little effect on the self–control of those focused on weak ties
while browsing a social network" (2013, p.92). This paper will help one understand their motives
that take place while social networking. Five studies were done through out this paper, but only
three were very supportive of their theory. The first study focused on proving "social networking use
increases self esteem primarily for those focused on strong ties while browsing the network"
(Wilcox & Stephan, 2013, p. 93). They expected that those focused on strong ties would have a
positive impact on self–esteem, but what they did not expect was the same for weak ties as well.
The methodology for this was done by design, survey and experimentation. They took 100 random
US participants and put them into four different groups. The groups were "browsing: Facebook
versus no Facebook" (Wilcox % Stephan, 2013,

Arundel Partners Case
Arundel Partners: The Sequel Project
The maximum per–film price for the sequel rights that Arundel Partners should pay is $5.12M.
If Arundel Partners were to use the traditional DCF methods to find the value of the sequel rights,
the NPV would be –$8.42M loss per–film (see Appendix 1).
Calculation Details
We assume that Arundel Partners will purchase a portfolio of films similar to one used in the
analysis. The average hypothetical net inflow of the sequel ($21.57M) is used to figure out the value
of the state variable for the real options model. The state variable is the average hypothetical net
inflow of the sequel, discounted using a WACC of 12.36% back to 1989. Discounting back to 1989

This approach allows for valuing real assets with some degree of operating flexibility, incorporating
the value of the flexibility into the option price. It values the option to exercise but not the
obligation to make future investments. It is based on the law of one price (the price of two portfolios
with the same cash flows in every state of the world must be the same). Option value increases with
great uncertainty (see Exhibit 3). The major uncertainties are Arundel Partners' WACC and volatility
of return on assets. A sensitive analysis shows the degree of changes with the changing
uncertainties. The major disadvantage of this approach is that it often requires changes in business
process. In Arundel Partners' case, the terms and provisions in the contract will mitigate some of the
disadvantages.
Additional terms and provisions for the sequel rights portfolio
The terms and provisions for the sequel rights for one or more studios' entire production:
The maturity or expiration rate of exercising the sequel rights is 1 year. This will allow Arundel
enough time to make a decision about making a sequel and enable it to more quickly write off its
investment in rights it chose not to exercise.
Arundel Partners can chose to produce the sequel or hire another firm to do so.
Arundel Partners will grant right of first refusal to the studio on any rights it planned to sell. If the
studio is not interested, Arundel Partners can sell the rights to the highest

Math Anxiety Essay
The Anxiety Math Can Bring
The struggle that is seen a lot with students as young as first grade deals with the fear of math. In
general, math seems to be the number one fear in the eyes of students who in the past have had bad
experiences in the subject. It can seem strange for those who have never felt the anxiety and pain it
brings. For most people, numbers come natural in figuring out when solving and following step by
step functions to get the answers correct. There is hope in finding ways to better cope with math
anxiety.
Exactly what is math anxiety? People may have their own view on it and I have learned that the
initial anxiety can exhibit in physical systems that are sweating, trembling, difficult swallowing,
nausea, vomiting, and heart palpitations (Bonander,
2012). To feel sickness and discomfort may have yourself question is it really worth it. The worry of
having to go to math class and having one or all of those physical symptoms happen to yourself can
bring embarrassment which does not help the situation at all. In many cases students feel like the
easy way out is to quit and not try to solve the work. It is an irrational fear of mathematics that can
range from a simple discomfort associated with numerical operations to total avoidance of
mathematics and mathematics classes (Mathison, 1977). Teachers can usually spot these symptoms
with their students and are quick to help out. Just going to class for these students is a challenge
itself. Second

optimisation problem A multiobjective problem can be viewed as well and if we consider a
minimisation problem for all objectives functions: m functions to optimize and p constraints to
satisfy. The main goal of all optimisation methods is to find an optimal solution of those problems,
and we should precise that a multiobjective problem have many objectives to optimize these
functions are mutually contradictory, so to make a comparison between solution and an other one,
we should describe a relation to made this appreciation, The Pareto Dominance relation can do this.
Considering a minimisation problem, lets u and v two vectors. A solution is an Pareto optimal
solution if and only if it doesn't exist an other admissible solution x where f(x) dominate . So a
solution of an Multiobjective problem is a set of solutions which they are not dominated by any
other solutions, we call this set the "Pareto front" 2 Related work In this

A Historical Perspective On Anxiety Management Training Essay
In the article by Richard M. Suinn, of Colorado State University, titled "Clinical Practice, University
Research, and Students: A Historical Perspective on Anxiety Management Training" from The
American Psychologist, Suinn discusses the history and application of Anxiety Management
Training, AMT.
He first explains his development of AMT through is many years of educating at various
universities. Suinn first talks how he first "examined how anxiety influenced the relationship
between self–acceptance and acceptance of others and the association between anxiety and
identification" at Whitman College. (Suinn, 1995, p. 287) After many years of research he along
with one of his student, Hunter Hill, they found "that anxiety disrupts the trend for self–perceptions
to color evaluations of others and is significantly associated with low self–esteem." (Suinn, 1995, p.
287) While at Whitman he also conducted research with another student, Tom Smith, where they
hypothesized that is a correlation between high identification and low anxiety. However, this
hypothesis was proven to be wrong and they found no relationship between the two. Suinn, then
talks about his time at the University of Hawaii. Here, along with some of his students, investigated
if group desensitization or individual desensitization was more effective. It was found that they were
both equally affected, even more so they discovered that a briefer approach was just as successful as
a longer approach when reducing

I believe the best way to solve this is too evaluate the three alternatives that must have the same

What initial salary would Ben need to receive to make him indifferent between attending Wilton

of being able to pay cash for his MBA, Ben must borrow the money. The current borrowing rate is

the calculation of the present values of the option. The payment terms of the loan should also be
specified. He will have to think and consider for how long it will take for him to pay off the loan. He
would then need to consider the present value of the cost for attending Wilton or Mount Perry and
deduct it from the amount that he expects to receive. He may or may not get the job offer after the

In a first step we have to postulate when the successful exit is going to happen. Normally this period
is assumed to be between 3 and 7 years long. In our case, we make the assumption that a successful
exit is going to happen in 1999. Since we are only concerned about the successful scenario, we go
along with the projection of AccessLine, which is probably overoptimistic, and use its expected
revenue of 208M at the time the exit happens. After the IPO, we presume the company will grow at
a high rate for the next five years in the 75 percentile as proposed by Metrick, Andrew and Ayako
Yasuda in their "Venture Capital and the Finance of innovation" book. We chose five years since the
typical firm reaches maturity within five years after the IPO. Besides, we assume a tax rate of
30.64% given by the industry average (Damodaran 2013). As a discount rate, we use simply the
industry average. Alternatively, we could use the Betas of the comparable companies. This gives us
an unlevered average beta of 0.5*(1.39+2.03) since both companies are completely equity financed.
The risk free rate was given by 7.1%, if we assume a risk premium of 5.79% (Damodaran for
1.4.13) we get a cost of capital of 16.9% using the CAPM equation. Because we only have two
comparable companies we opt to do our calculations with the industry wide average discount rate.
The operating margin at the exit date is estimated in a way that we reach a Net

Description Of The Model Of 11 Submodels Essay
The model
The model consisted in 11 submodels, one equation was used to calculate a random population and
simulate the IAA to each individual for all treatment (level of methionine+cysteine). The FI and
MCI are describing according to the performance of the flock population, with the price of amino
acid is calculated the feed cost with the increase of IAA. The model preconized that the optimum
IAA is dependent on the economic variables, therefore the model defines the NR with the variation
of the amino acid prices and sale poultry. The optimum IAA is determined by the relationship
between IAA and NR.
The input of model is: 1 – μ of broiler; 2 – SD, 3 – parameters of the monomolecular model, 4 –
cost of standard diet, 5 – price of sale poultry, 6 – parameters to estimate energy, 7 – number of
animals that wish to simulate. The model output is the NR and the optimum amino acid intake.

The model described simulates the potential performance and hence nutrient requirements at a flock
bird level, for this simulation needed of the µ and σ of the population, this parameter can be
acquired from experiments or literature data. Body weight gain (BWG.R) with random numbers

Notes On The And Binary Conversion
6. Gray to Binary Conversion A binary image is the matrix comprising of only 0's(black) and
1's(white). It can be implemented by using the command im2bw in MATLAB. Thresholding
concept has been used in this algorithm. The threshold concept works by choosing a threshold value,
T, automatically and then extract (or separate) object from background. The threshold function of
the binary image is defined as g(x,y) = {█(a,if (x,y)>T@b,if (x,y)≤T)┤ Pixels having a value
correspond to object and pixels with b value correspond to background. Usually, a=1 (white) and
b=0(black) by convention. When T is a constant applicable over an entire image, the above equation
is referred to as Global thresholding. In the algorithm, global thresholding concept is used.
Enhanced image is converted into binary format by using the command im2bw and the resultant
image is shown below Fig. 11 Gray to Binary conversion 7. Morphological Operations
Morphological operators take a binary image and structuring element as an input and combine them
using a set operator such as union and intersection. Structuring element have dimension of 3*3 and
its origin is at the center pixel. The pixels of the structuring element are compared with each pixel of
an image. If it matches the condition defined by the set operator then the pixel is set to a pre–defined
value (0 or 1 for binary images). There are two basic types of morphological operator, which is used
in this algorithm. 7.1 Dilation Dilation

I teach in a computer lab and incorporate technology in the classroom. I use a supplemental online
program by Pearson Education, Math Lab Plus (MLP), to reinforce the material. The program has
an online discussion component. To foster a sense of community in the classroom, the first
assignment I post is for students to write a brief bio about themselves, including their goals and
aspirations for taking the course. I respond to each entry to make sure students know they are seen
and heard and that I care about their success. As part of their participation grade, students are
required to respond to two other students in the course. This helps them recognize they are part of a
community of learners and not just another student lost in the crowd. Students are placed in
cooperative learning groups where they work with a partner to improve their understanding of
different math concepts.
Additionally, I use a toolbox of leadership strategies that are implemented throughout the semester
including: reflective practice, naming and reframing the questions that arise and analyze the results,
integrating theory into practice. Carl Buehner said, "They may forget what you said, but they will
never forget how you made them feel."

This means the researcher needs to consider the overall implication of the details. The researcher
needs to consider the size of the study, is it local, statewide, or nationwide. What will be the time

(2013) point a difficulty researchers run into stating, "A researcher talks about the problem but never
actually states what the problem is" (pg. 33).
4. Have an open mind concerning the realm of possible solutions to the problem. "Good researchers
try to keep open minds about what they might find. Perhaps they will find the result they hope to
find, perhaps not. Any hypothesis should be stated as exactly that – a hypothesis – rather than a
foregone conclusion" (Leedy, Ormrod, 2013, pg. 34).

The impulse generator comes into business here.Studying the lightning characteristics by creating
the similar impulse using the impulse generator helps in assessing the strength of the electrical
equipment's against transient and lightning impulse. This has been practiced by industrialists and
researchers for so many years. Massive and extremely large test apparatus are used for the impulse
wave generation. To ease down the process with reliable and accurate results, here for the design
4A, a GUI (Graphical User Interface) based software for impulse generator and lightning
characteristics simulation. This would be the only prototype standalone software which caters to the
impulse waveforms studies. The GUI will have the text entry fields to input the circuit parameters
and there will be plotting space where the impulse waveform will be plotted.
The framework of the software will be the mathematical model of the impulse generator circuit. For
different input values, the corresponding waveforms will be obtained. The main focus of this
research will be towards accessing waveforms and its characteristics that corroborates the industry
standard and laboratory experimental values with expected accuracy not lesser than 60%.This
software will be made available to work in cross platform operating systems such as Windows,
android, Mac etc. so that the user can download and install the application in their favourite media

Effectiveness Of High Preference ( High P ) Intervention
Introduction
Noncompliant behavior in an academic setting can result in missing opportunities, falling behind in
schoolwork, missing instruction and disrupting the class. It is critical that noncompliant behavior be
decreased (Banda & Kubina, 2010). This study focused on a thirteen year old middle school student
with Autism. Brad was a student who displayed academic noncompliance particularly with
mathematics tasks. Brad was fully capable of completing all of the academic demands that were
present, but showed resistance in completing missing addend math problems.
The purpose of this study was to examine the effectiveness of high preference (high–p) intervention.
High–p intervention consisted of presenting two to three high–p tasks before the presentation of a
low preference (low–p) task. Preference of tasks was determined with a pre–study preference
assessment.
Method
Participant The participant was Brad, a thirteen–year–old boy, diagnosed with Autism and Pervasive
Developmental Disorder. Brad received speech and language services once a week and had in class
paraprofessional support. The Woodcock–Johnson Revised Achievement Tests (WJ–R) determined
grade level performance in word identification and below grade level performance in
comprehension and problem solving. Brad's teacher requested help after identifying his need for
additional support for low–p tasks. REWORD
