Topic: Schizophrenia

1. Review the readings on schizophrenia, DSM-V criteria and briefly describe schizophrenia, and current understanding of the disorder.

2. Conduct a literature search and address one of the following questions in a brief essay:

a) What is the relationship (if any) between violence and schizophrenia?

b) What role, if any, does stigma play in help seeking, treatment, and recovery?

1. Calculate the frequency in Hz of a typical green photon emitted by the Sun. What is the physical interpretation of this (very high) frequency? (That is, what is oscillating?)

In the previous question, you designed a simple algorithm to create a class list application. In this question, you
will implement the same application in Java. To do this, you will need a working version of a Student ADT, a List
ADT, and the List Iterator. You may start with your own Student ADT, or you can start from the solutions to
Assignment 2. You will be given a working version of a List ADT.
Recall that your application does the following:
• Create a class list of students
• Display every Student record in the class list to the console.
• Give every student a bonus mark on the final exam. It does not matter how much of a bonus you give.
• Display every Student record in the class list to the console, to show the changes to the records.
You must store Student objects in a List, using the given List ADT.
You are to use the List Iterator for any task that requires looking at every element in a list (the last two items
above).
Here’s a guide for you to help you manage this task.
1. Download the BasicLinkedList.java and List.java files from Moodle.
2. Obtain the StudentADT.java and Student.java files from either your solution or the model solution of assignment
3. Create a new application class called ClassListApp.java, that contains a main method. Make sure that you
include import java.util.*; on the top of the file.
4. Take your design for Exercise 1, and copy it into ClassListApp.java, as comments. Implement the design in
steps (not all at once). Every time you have a step implemented, compile and test.

Here are the java source file already given

1. Imagine that you want to obtain a loan from a bank for a business that you operate through a corporation. The bank wants assurances that the loan will be repaid. It gives you a choice to advance the loan to the corporation and for the bank to obtain from the corporation a mortgage registered against land owned by the corporation, or to advance the loan to the corporation but to ask you to give the bank a personal guarantee of the loan. What are the advantages or disadvantages under either scenario?

Write a function named int2ordinal that takes an integer as its only parameter and returns the number with its appropriate suffix as its result (stored in a string). For example, if your function is passed the integer 1 then it should return the string "1st". If it is passed the integer 12 then it should return the string "12th". If it is passed 2003 then it should return the string "2003rd". Your function must not print anything on the screen.

You can use the remainder operator to extract the last digit of an integer by computing the remainder when the integer is divided by 10. Similarly, you can extract the last two digits of an integer by computing the remainder when the integer is divided by 100. For example 29 % 10 is 9 while 1911 % 100 is 11. Then you can construct the string that needs to be returned by your function by converting the integer parameter into a string by calling the str function, and concatenating the appropriate suffix using the + operator.

An experiment to measure the value of g is constructed using a tall tower outfitted with two sensing devices, one a distance H above the other. A small ball is fired straight up in the tower so that it rises to near the top and then falls back down; each sensing device reads out the time that elapses between the ball going up past the sensor and back down past the sensor.

(a) It takes a time 2t₁ for the ball to rise past and then come back down past the lower sensor, and a time 2t₂ for the ball to rise past and then come back down past the upper sensor. Find an expression for g using these times and the height H. (Use the following as necessary: t₁, t₂, and H.)

(b) Determine the value of g if H equals 21 m, t₁ equals 4 s, and t₂ equals 3.42 s.

Thank you for the help- I can't figure out how to set up the first part and get an equation that will actually allow me to solve the second part. Let me know what steps you used. Thanks!

A crate rests on a frictionless incline, and is attached to a bucket of nails through a frictionless and weightless pulley as is shown.
Crate = 12.0 Kg Bucket = 25.0 Kg Angle = 20 degrees





a) You may assume that the crate accelerates up the incline. Calculate the magnitude of the acceleration of the crate. (8 points)










a = ________

b) If the acceleration of the crate was calculated to be a negative value, what could be said about the assumption in part a) that the crate moved up the incline? (2 points)






c) What is the magnitude of the Normal force of the incline pushing up on the crate (find N the Normal Force) ? (6 points)







N = _________

d) It turns out that there really is friction between the crate and the incline. The value of the friction coefficients is Us = 0.25, and Uk = 0.15. What will the acceleration be of the crate up the incline if you take in account friction? (8 points)











a = _________

e) A workman who was watching the crate accelerate up the incline decides he wants to adjust the system so that the crate maintains a steady speed while traveling up the incline. He removes nails from the bucket to achieve this goal. Taking into account the friction from part d), what should the new mass of the bucket of nails be to make this happen? (8 points)






m = ___________

e) LIST the three effects that account for the downward slope of the AD curve.
