PSY0003 Pamphlet Humanities Assignment Help
For this task, prepare a pamphlet suitable for distribution to parents, teachers, and caregivers of young children, about physical development in childhood or adolescence. Include material on how caregivers can promote positive physical development in children or adolescence. Be sure to include at least one reallife resource (i.e., a camp, a club, an organization, website) in Oklahoma that promotes physical development for children or adolescents. You may include appropriate graphs and visual enhancements to make your brochure engaging.
Length: 24 pages, not including title and reference pages
References: Include a minimum of five scholarly resources.
Your pamphlet should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards.

Use whatever software resources make the most sense (Tableau, Excel, R, etc.) given that you are working with more than 500 time series. Science Assignment Help
Assignment
1.Plot all the series (an advanced data visualization tool is recommended) – what type of components are visible? Are the series similar or different? Check for problems such as missing values and possible errors.
2. Partition the series into training and validation, so that the last 4 years are in the validation period for each series. What is the logic of such a partitioning? What is the disadvantage?
3. Generate naive forecasts for all series for the validation period. For each series, create forecasts with horizons of 1,2,3, and 4 years ahead (Ft+1, Ft+2, Ft+3, and Ft+4).
4. Among the measures MAE, Average error, MAPE and RMSE, which are suitable if we plan to combine the results for the 518 series?
5. For each series, compute MAPE of the naive forecasts once for the training period and once for the validation period.
6. The performance measure used in the competition is Mean Absolute Scaled Error (MASE). Explain the advantage of MASE and compute the training and validation MASE for the naive forecasts.
7. Create a scatterplot of the MAPE pairs, with the training MAPE on the xaxis and the validation MAPE on the yaxis. Create a similar scatter plot for validation MASE vs. MAPE. Now examine both plots. What do we learn? How does performance differ between the training and validation periods? How does performance range across series?
8. The competition winner, Lee Baker, used an ensemble of three methods:
• Naive forecasts multiplied by a constant trend (global/local trend: “globally tourism has grown “at a rate of 6% annually.”)
• Linear regression
• Exponentiallyweighted linear regression
(a) Write the exact formula used for generating the first method, in the form Ft+k=…(k=1,2,3,4).
(b) What is the rational behind multiplying the naive forecasts by a constant? (Hint: think empirical and domain knowledge)
(c) What should be the dependent variable and the predictors in a linear regression model for these data? Explain.
(d) Fit the linear regression model to the first five series and compute forecast errors for the validation period.
(e) Before choosing a linear regression, the winner described the following process
“I examined fitting a polynomial line to the data and using the line to predict future values. I tried using first through fifth order polynomials to find that the lowest MASE was obtained using a first order polynomial (simple regression line). This best fit line was used to predict future values. I also kept the [R2] value of the fit for use in blending the results of the predictor.”
What are two flaws in this approach?
(f) If we were to consider exponential smoothing, what particular type(s) of exponential smoothing are reasonable candidates?
(g) The winner concludes with possible improvements, one being “an investigation into how to come up with a blending [ensemble] method that doesn’t use as much manual tweaking would also be of benefit.” Can you suggest methods or an approach that would lead to easier automation of the ensemble step?
(h) The competition focused on minimizing the average MAPE of the next four values across all 518 series. How does this goal differ from goals encountered in practice when considering tourism demand? Which steps in the forecasting process would likely be different in a reallife tourism forecasting scenario?
Case Study Assignment #2 is based on the second case presented in Chapter 11 of the Practical Time Series Forecasting textbook (pages 215218). This case is to practice forecasting multiple time series, all related to tourism demand. Read the information on those pages of the textbook. The data can be found in tourism_data.csv. You may also want to view the article Athanasopoulos et al. – 2011 – The tourism forecasting competition.pdf
Your assignment is to address the questions on pages 216218. Use whatever software resources make the most sense (Tableau, Excel, R, etc.) given that you are working with more than 500 time series. (Remember that for the regression model in 8(d) you are only to forecast the first 5 series). Your response to the case will be answers to the text questions (upload Excel or Tableau files, along with a Word file or .pdf with responses to the written questions). Document any sources used.

PSY0002 Analyze Parenting Styles Humanities Assignment Help
This week, your assignment has two parts. You will combine both parts and submit your assignment in the same document.
Part 1:
Based on what you have studied about Baumrind’s parenting styles, prepare a worksheet for parents. This is a worksheet that they will be able to use to monitor and better understand their own parenting styles. On the first page, identify and briefly describe each parenting style. On the second page, provide a chart for the parents to use to monitor their own parenting styles. On one side of the chart offer space for the parent to briefly describe an event that happened between themselves and one of the children, and on the left hand offer an area for them to check off which type of parenting is reflected.
Prepare one example for them and allow space on the handout for them to add their daily parenting experiences.
Length: 23 pages
Part 2:
Present an annotated outline for your Signature Assignment (A copy of an essay with the signature assignment topic will be attached. Use that to help create the annotated outline.) (Hint: Use the required points in the Signature Assignment as the main topics in the outline. Include subtopics as appropriate to your specific research project.) In the outline, include citations for each of the topics and subtopics. You should have at least five citations. Clearly mark sections in the outline where you need to do more research to find support for the paper, so that you can be sure to find those resources as you prepare your final paper.
Length: 34 pages
References: Include a minimum of five scholarly resources
Your paper should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards.

Project Scenario and Questions
The Scenario:
The Oakland Athletics home game at O.co Coliseum,
7000 Coliseum Way, Oakland, CA 94621, is held on August 18th in the middle of
one of the hottest summers on record in California. On this particular day,
the high is 110 degrees. In attendance are approximately 35,000 spectators
and 5,000 players, team staff members, support staff, coliseum employees,
and venders for a total of around 40,000 people in an area of about 157
acres. O.co Coliseum is located in the San Leandro Bay area and has 19
bridges that connect it to the city of Oakland.
The Situation:
A large scale, well planned, and wellfunded
terrorist attack has been planned by a California based radical terrorist
group known as BC. The members of this terrorist group want to force the
government to divide California into three separate states. They are violent,
willing to die for their cause, and are home grown, so they know the culture
and can blend into a crowd. Ten of the terrorists are employees at the
coliseum. On this day, they have driven vans to work that are full of
weapons, explosives, ammunition, and other supplies.
During the 3rd inning, the attack occurs. Nineteen small boats are
loaded with explosives. Each boat is manned with five heavily armed terrorists.
The radicals tie off their boats under the 19 bridges. The extremists exit the
boats, enter the parking lot of the coliseum, and remotely detonate the
explosives, destroying 18 of the 19 bridges, but leave the North Bridge
partially intact. Just prior to the bridge detonations, four UHaul trucks with
two occupants in the cabs and 10 heavily armed terrorists in the back of each
truck drive through the North Bridge Gate, also entering the parking lot. Each
UHaul truck also contains a large amount of extra supplies to keep the
terrorists’ operation going. The terrorist force is comprised of 153 wellarmed
members who are willing to die for their ideology.
Once the coliseum has been cut off from the city of Oakland, the
terrorists use cars from the parking lot to block the remaining portion of the
North Bridge. Other cars in the parking lot are set on fire so the heavy smoke
will block the view of law enforcement helicopters. All coliseum exits are
blocked by burning vehicles and by armed terrorists. Exits that cannot be
blocked are destroyed with explosives. Innocent bystanders in the parking lot
are shot and killed. Identifiable armed security and Oakland Police Officers
are attacked and also shot and killed by the radicals who have highpowered
rifles and automatic weapons. It is believed that the inside of the coliseum
has been booby trapped with explosives.
The goal of the terrorists is to contain as many people as possible
inside the coliseum and to prevent escaping baseball fans outside of the
coliseum from swimming to safety by using the surrounding waterways. Since
there are several terrorists outside of the coliseum, they are able to warn
the extremists inside the ballpark in plenty of time to stop fans from
escaping.
The Tactical Situation:
Local law enforcement consisting of 50 police
officers who were assigned to the game along with 200 regular security
guards are injured or dead. Hundreds of game fans are dead in the parking
lot and in the coliseum with hundreds more injured. Mutual aid has
responded to the event. Police SWAT teams, Sheriff’s SEB teams, and FBI
SWAT teams are on standby while they assess the situation. Over 500 law
enforcement members who can enter the coliseum are under fire. Other
members of law enforcement are on the opposite shore of the coliseum to
offer covering fire for victims that are trying to escape by swimming to
safety.
The exact number of terrorists is not known, but eye witnesses who
managed to escape in the initial attack and law enforcement officers report
approximately 150 terrorists involved in the incident. The police also report
having neutralized 10 of the terrorists, so there are around 140 observed
terrorists left.
Negotiations have been established, and the situation is now in its
second day. With little food or water for the tens of thousands of victims
still alive inside the coliseum and with a constant summer heat of 110
degrees, the situation is dire.
Armored vehicles have been gathered from surrounding agencies, and the
California National Guard has been activated. The armored vehicles have been
parked in a 180 degree perimeter around the coliseum to offer cover for law
enforcement and for victims able to escape across the water to safety.
NOTE: No federal troops can be used because it would violate the Posse
Comitatus Act. However, a loophole allows for victims to be taken to the Navy
because they are offshore. During Hurricane Katrina, National Guard medivac
teams were able to take victims to the Navy because there were no boots on the
ground.
Instructions:
As you write your draft and final essay, be sure
to answer each of the 10 sets of questions listed below. You must indicate in
your paper which set of questions you are addressing. For example, (1.) The
180 degree perimeter will be… Your paper does not have to address the
questions in any particular order. You must follow APA guidelines.
Your Task:
You are in charge of all Fire Department assets; EMS; and
coordination with hospitals, clinics, and the USNS Comfort, which is birthed
just outside of San Leandro Bay. The Governor of the State of California has
declared this situation a State of Emergency, so any resources you need will
be available. Landing Craft Air Cushions (LCAC) can hold up to four fire
trucks each. With all but one severely damaged bridge out, the only way to
get fire trucks and other heavy equipment into the area is by amphibious
landing on the west side of the coliseum. There are large pumps staged on the
west side to supply water to the fire trucks.
Over the past two days and nights, a few hundred victims have been able
to escape by crossing the water; however, most are severely injured.
 With your 180 degree perimeter around the coliseum, where will you
have your EMS teams set up so they can aid those who have
escaped? How will you get them to a medical facility? How
will you decide which facility they are taken
to?
Anticipating a large number of casualties, you have coordinated
with the local hospitals, clinics, and the United States Navy, which deployed
the USNS Comfort.
 How will you decide which casualties go to what medical
facility?
During this horrific event, the media will be everywhere, but will
be unable to fly due to the heavy smoke. They will be able to see your
perimeter and assets being gathered.
 How will you keep the media from giving the terrorists critical
intelligence by inadvertently recording where they should not
video? Can you use the media to your advantage in this
situation, or will the media just be a hindrance?
Due to the two days of extreme heat, exposure, and dehydration,
law enforcement has decided to enter the coliseum. It will be a fight to
secure the location. SWAT teams will need to fly in by helicopter, while
under fire and with low visibility, to bring the coliseum and parking lot
under control.
 When SWAT enters the parking lot, it appears to be cleared of
terrorists who have likely moved into the coliseum. SWAT teams
need to enter the coliseum, but it will require fire fighters to
break open a large hole in one side of the coliseum. To avoid
the potential injury of patrons, explosives have been ruled out
as a means to gain entry. What fire department assets will you
deploy to break a hole into the coliseum? What equipment will
you need? What security assets will you require to ensure the
safety of the fire fighters breaching the coliseum
walls?
While the breaching teams are working, other fire fighters must
extinguish burning cars in the parking lot that have been kept ablaze by the
extremists. The fires are hindering the views of helicopters that are
deploying additional SWAT teams.
 With multiple cars burning all around the coliseum, what assets
are you going to deploy to extinguish these fires? Where are
you going to start, and what type of security are you going to
provide for each fire truck?
During the operation to secure the coliseum, the responding SWAT
teams have to pick a direction to move in. You must decide in what direction
they should move.
 You have the option to send EMS in with the SWAT teams, and you
have at your disposal EMS from city, county, state, and
National Guard agencies. Are you going to send in EMS? If so,
with which wave will you send them? If not, why not, and how
are you going to use EMS?
During the operation to secure the coliseum, the crowds in the
areas not yet secured are coming under fire from the terrorists. The crowd
begins to resist the terrorists in order to aid the incoming SWAT teams who
ultimately kill or capture the terrorists.
 You receive reports that the coliseum appears to be secured,
and there is no active resistance. The fires are extinguished in
the parking lot, and the outer wall of the coliseum has been
breached. Because there are nearly 38,000 casualties with
injuries ranging from exposure, dehydration, and gunshot wounds,
what is your next move?
The casualties have been triaged, the National Guard has deployed
temporary bridges, and you have a fleet of helicopters, hundreds of
ambulances, and other emergency vehicles at your disposal.
 How are you going to coordinate with your resources to evacuate
the remaining 38,000 survivors still at the
location?
Keeping in mind this is an active crime scene, there will be many
deceased in the parking lot and inside the coliseum.
 Most of the fatalities will be game spectators, but there will
also be victims from fire departments, law enforcement
agencies, and the National Guard, so emotions will be high.
How will you coordinate the removal of the deceased, and with
whom? Will you leave them at the venue or remove them to a
staging area for identification and proper removal? For scenario
purposes, there are 2,531 victims who were declared dead at the
venue. There are an additional 253 deceased at local hospitals
and on the USNS Comfort.
The number of terrorists that have been killed or captured is 140.
Due to conflicting accounts from baseball fans who were able to escape from
the coliseum, law enforcement may not know there were actually 153 terrorists
involved.
 As the head of the fire departments, EMS, and hospital
coordination, you know there may be terrorists still on the loose
who have gained valuable intelligence on how the emergency
services will respond. What steps are you going to take to
prepare, plan, and train for the next possible
attack?
The following are suggested resources to use in your
scenario:
 Oakland City Emergency Services;
 Alameda County Emergency Services;
 California Highway Patrol;
 California Department of Forestry and Fire Protection;
 all hospitals and medical clinics;
 surrounding counties, San Francisco, San Mateo,
Santa Clara, Marin, Sonoma, Napa;  USNS Comfort (TAH20);
 all parks, colleges, schools open parking lots, Federal
Bureau of Investigation (FBI);  California National Guard; and
 four Landing Craft Air Cushions (LCAC) from Camp
Pendleton.
