Three Sociological Paradigms

Let’s assume that a “welfare stigma” exists in American society. Many people have a perception that welfare recipients are “lazy” and that they “steal” the tax money. People also believe that welfare recipients make babies to stay on welfare instead of working. In fact, most welfare recipients are children, the elderly, the sick, the mentally and physically handicapped or young mothers with few skills. Explain why this “welfare stigma” exists by using TWO of the three sociological paradigms, structural functionalism, social conflict paradigm, and symbolic interactionism.

Show that if all nodes in a splay tree are accessed in sequential order, then the

The annual sales for​ Salco, Inc. were $ 4.46 million last year. The​ firm's end-of-year balance sheet was as​ follows:  Salco's income statement for the year was as​ follows:

a. Calculate​ Salco's total asset​ turnover, operating profit​ margin, and operating return on assets. b. Salco plans to renovate one of its plants and the renovation will require an added investment in plant and equipment of $ 1.09 million. The firm will maintain its present debt ratio of 50 percent when financing the new investment and expects sales to remain constant. The operating profit margin will rise to 13.9 percent. What will be the new operating return on assets ratio​ (i.e., net operating income divided by total ​assets) for Salco after the​ plant's renovation?

c. Given that the plant renovation in part ​(b​) occurs and​ Salco's interest expense rises by $ 53,000 per​ year, what will be the return earned on the common​ stockholders' investment? Compare this rate of return with that earned before the renovation. Based on this​ comparison, did the renovation have a favorable effect on the profitability of the​ firm?

5.16 Implement function indexes() that takes as input a word (as a string) and a onecharacter letter (as a string) and returns a list of indexes at which the letter occurs in the word.

>>> indexes('mississippi', 's')

[2, 3, 5, 6]

>>> indexes('mississippi', 'i')

[1, 4, 7, 10]

Explain how the modular kernel design combines the benefits of both the layered and microkernel structures.

make a python script that has the following typed:

school = “cochise college”

place = “online”

Then do the following with the given parameters.Set the script to have a function that takes two parameters, school and place, have your function return the first 5 characters of each parameter value, utilizing a slice. Change the script to have a function that takes two parameters, school and place, have your function return the first character of each parameter, utilizing an index value. Then, Modify the script to have a function that takes two parameters, school and place, have your function return the last character of the variable place for each parameter, utilizing an index value. Next, modify the script to have a function that takes two parameters, school and place, have your function return the variables school and place in title form. Lastly, modify the python script to have a function that takes two parameters, school and place, have your function check to verify that ‘cochise’ is in the school parameter and ‘online’ is in the place parameter. If it is have the function return, ‘Great you go to Cochise College Online!’, else have the function return, ‘You should check out Cochise College Online!’

The objective is to read the last five lines of a file (text file) in Perl. I wrote down what I have written so far in Perl but I get an error message saying, "Can't open sample.txt: No such file or directory." The sample.txt file is located in the same directory that I am executing the perl scripts on the command line.

I'm doing a practice test and I can't seem to find the answers anywhere for these specific questions. If someone could please help clarify so I can learn that would be helpful!

1. Identify the true statements. Select ALL that apply.

a. Setters and getters are not required for public instance variables.

b. A setter method is return-type void and takes a parameter of the same type as its field.

c. A getter method has the same return-type as the field it retrieves and takes no parameters.

d. Every private instance variable in a class definition must have a mutator method.

2.
private char gender;public class Person {

static int number;

//...

public static void main(String[] args) {

Person person;

   //...

}

public static void callPerson(int hours) {

d. A non-static method can be called from a static method.

4. What does the public visibility modifier mean?

a. means accessible from any class in the same package.

b. means accessible to the current program.

c. means accessible to any method in the class.

d. means accessible from any other classes.

5.

3. public class Person {
4. private double salary;
5. public Person() {
6. salary = 1000.0;
7. }

What type of constructor is illustrated by lines 5 through 7?

6. Identify the true statements. Select ALL that apply.

b. Static variables and static methods of a class can be accessed by an object of that class and by the class name.

c. Static variables have a default value of null.

d. Anonymous objects are possible in Java.

This program does password verification. It gives the user three attempts to type in the correct password. Assume that the password is "COMSC110" (You can hard-code this). If the user types in the correct password, display a message saying "Login successful" and break out of the loop, otherwise display " Login Failed" and go to the next iteration. If the user enters three unsuccessful entries, then display a message saying " Too many attempts, Try again later", Use a while loop.
