Question: Why is evacuation planning so difficult? What kinds of things can go wrong during an actual evacuation? What do you think can be done to minimize these potential setbacks?

Instructions:   

There are a few important rules to observe during the Group Discussion process: 1) no profanity or offensive language; 2) no personal attacks, and 3) be courteous and professional when you respond to one of your classmates – part of the education process involves disagreeing without being disagreeable, which is not synonymous with disrespect. However, if I read something that I don’t think is appropriate, then I will immediately remove it from the forum.

The following are the four (4) grade ingredients for each Group Discussion throughout the Semester:

First, choose a topic, conduct research, and write at least three (3) good paragraphs in your response.

Second, always include your personal perspective and comment on the subject matter of the topic you have chosen to discuss. Do not merely define the topic/subject matter. 

Third, always be sure to cite a legitimate reference source related to your research findings – it’s ok to submit a direct quote but be sure to cite the reference in a formal APA (7th edition) bibliography format at the end of the assignment. The course textbook Introduction to Emergency Management (Haddow, 2020 / 7th edition), is acceptable as a reference, as you bought it and should use it accordingly. Again, however, be sure to cite other relevant sources. DO NOT simply cut/paste information, nor ever use Wikipedia, or you will reap what you sow!

Fourth, late submissions will not be accepted and will result in loss of grade points for the course.

Provide in the plain text R commands that finds/solves the following:  

1. The student directory for a large university has 400 pages with 130 names per page, a total of 52,000 names. Using software, show how to select a simple random sample of 10 names. 
2.  From the Murder data file, use the variable murder, which is the murder rate (per 100,000 population) for each state in the U.S. in 2017 according to the FBI Uniform Crime Reports. At first, do not use the observation for D.C. (DC). Using software:
   1. Find the mean and standard deviation and interpret their values.
   2. Find the five-number summary, and construct the corresponding boxplot.
   3. Now include the observation for D.C. What is affected more by this outlier: The mean or the median? 
3. The Houses data file lists the selling price (thousands of dollars), size (square feet), tax bill (dollars), number of bathrooms, number of bedrooms, and whether the house is new (1 = yes,0 = no) for 100 home sales in Gainesville, Florida. Let’s analyze the selling prices.
   1. Construct a frequency distribution and a histogram.
   2. Find the percentage of observations that fall within one standard deviation of the mean.
   3. Construct a boxplot. 

Datasets needed are at Index of Data SetsUseful functions in R to solve problems in this assignment: sample, read.table, mean, sd, summary, boxplot, hist, table, cbind, length, case, tapply

 Do groups enhance or impair performance?

Introduction:

Does the thought of a “group project” send shivers down your spine?  If so, you aren’t alone.  Many students prefer working alone to working in a group.  But before you dismiss the benefits of working together, let’s explore what the research says about whether groups enhance, or impair, performance.

This assignment fulfills/Supports:

• Module Outcome: 1
• Course Outcome: 1, 2
• General Education Competencies: 1, 3, 5

The Assignment:

For this Discussion Board, complete the following steps:

Step 1:

1. Using the FTCC Library (either in-person or online), explore scholarly research on the following concepts:
   1. The social facilitation effect
   2. Social loafing
   3. Deindividuation
   4. Group polarization
   5. Groupthink

Step 2:

In your initial post, thoroughly discuss the following:

1. Based on your research, choose at least two of the concepts listed above and discuss how they could IMPAIR performance on a group task (identify a group task/activity and apply your discussion to that task).  Here’s an example: Social loafing is a common occurrence in academic group work.  When students are assigned a group project, there may be one or more social loafers in the group who do not complete their “fair share” of the work.  This happens because people who are part of a group feel slightly less responsible for the outcome and therefore don’t work as hard as they https://perfectwriterblog.com/education-homework-help/do-groups-enhance-or-impair-performance/ would if they were completing a project alone.  When this happens, other group members pick up the slack left by the social loafers.  Ultimately, this can impair group performance because…(explain how social loafing impairs group performance using the information from your research and your textbook). Remember- group work doesn’t always occur in an academic setting.  We work together in groups at our jobs, in our homes, and in social settings.
2. Next, discuss at least two ways that working in a group can ENHANCE performance on the same task you identified above.
3. Your discussion must be based on information from the scholarly sources you found through the FTCC Library.  However, you may add anecdotal information from your own life to justify your position.

Citing Sources:   You must use APA style to reference your source(s) at the end of your submission.  For this assignment, you must include reference information for your textbook and any articles or publications you use.  Information on how to format reference information (including a reference generator) in APA style can be found on the Purdue Online Writing Lab website at https://owl.purdue.edu/owl/research_and_citation/apa_style/apa_formatting_and_style_guide/general_format.html (opens in a new window).

Acceptable Length: 300-500 word initial post; 2-3 sentence responses to at least two classmates.

Formatting Requirements:

• Use 12-point Times New Roman or Arial font
• Use double line spacing in the document
• 1-inch margins all around

Grading criteria: For full points you must fully comply with each component of the Discussion Board Rubric.

Specifications: Post your initial response to the questions early in the assignment period so that others have time to respond to you. *NOTE*: You must submit your initial post before you will be able to view the posts of other students.  This prevents students from simply re-wording the posts of classmates.

To Submit: When you are ready to make your initial post, click on the “Module 2 Discussion Board” link above.  You will not see any other posts.  Click on “Create Thread” to type and post your initial post.  Once your initial post is submitted, you will be able to read and reply to your classmates’ posts.

Answer  each these questions in a paragraph with at least five sentences:  Include the question and number your responses accordingly. Provide a  citation for each answer. 

1. What is privacy?

2. What risks, if any, does facial recognition software raise?

3. How much information about you can be found on-line with a simple google search? 

4. How much information about you can be found by searching government and commercial databases?

5. Describe informed consent. 

6. Should secondary use of consumer provided data be available without notice to the consumer?

7. How do data mining and predictive analytics work? 

8. Watch this Science Friday video by Ira Flatow. And, offer your opinion – Are advancing algorithms taking our free will? 

9. Should Facebook be regulated, at least as far as it’s privacy and data policies? 

10. How many public cameras is too many?

Exp19_Excel_Ch06_ML1_Housing_Cost

Project Description:

Your friends, Elijah and Valerie Foglesong, want to build their dream house. They identified tentative costs, but they cannot afford the $414,717 estimated cost. You will use Goal Seek to determine an estimate of the total finished square footage they can afford. To help provide more flexibility in their decision-making, you will create a data table listing various finished square footages and their effects on the base house cost and total cost. Finally, you will create another data table showing combinations of square footages and lot prices to identify total costs.

     

Start   Excel. Download and open the file named Exp19_Excel_Ch06_ML1_HW-Housing   Cost.xlsx.   Grader has automatically added your last name to the beginning of the   filename. 

 

Assign the range names B9 (Base), B15 (Interior), B21 (Exterior), B23 (Lot).

 

Enter a formula in cell B25 to   calculate the total estimated cost. The total estimated cost is the sum of   the base house price (B9), total interior upgrades (B15), total exterior   upgrades (B21), and lot fee (B23). Be sure to use range names in the formula.

 

Use Goal Seek to determine the   total finished square footage(B7) to meet the total cost goal of $350,000.

 

Enter a series of total square   footage ranging from 1,800 to 3,600 in increments of 200 in the range D6:D15. Apply Blue font and Comma Style with   zero decimal places to the series.

 

Enter a reference to the base   house price in cell E5 and a reference to the total estimated cost in cell   F5.

 

Complete the single variable   data table in the range D5:F15. Be sure to use total square footage as the   column input. Apply Custom number formats to give appropriate descriptions to   the second and third columns. Apply these formats to the headings: bold,   center, and Blue font color.

 

Identify the square footage,   base price, and total cost in the data table that comes closest to their   goal. Apply Yellow fill color to those cells.

 

Copy the square footage   substitution values, range D6:D15 to the range H6:H15 and remove the fill   color. Enter these lot price substitution values in the range I5:K5: 90000, 96000, and 102675. Format these values with Accounting Number Format with zero   decimal places and Blue font color.

 

Enter the reference to the total   estimated cost in the appropriate location for the second data table. Apply a   custom number format to display Total Sq Ft in that cell. Apply Blue font and bold to that   cell.

 

Complete the two-variable data   table using total square footage as the Column Input and lot price as the Row   Input. Apply a Custom number format to the reference to the formula cell.   Apply Yellow fill color to the total price in each column that comes closest   to their goal.

 

Format results in both tables   with Accounting Number Format with zero decimal places.

 

Create a scenario named Ideal Costs, using Base price per square   foot and Lot fee (use cell references). Enter these values for the scenario: 80, 102,675.

 

Create a scenario named Increased   Costs, using   Base price per square foot and Lot fee (use cell references). Enter these   values for the scenario: 100, 110,000.

 

Create a scenario named Low Costs, using Base price per square   foot and Lot fee (use cell references). Enter these values for the scenario: 60, 80,000.

 

Generate a scenario summary   report using the cell references for Price per square foot and Lot Fee. Add   the appropriate formatting to the newly created report

In this exercise you’ll get an intuition for what happens when we use algorithms with different computational complexities to solve the same problem. Download these two sorting programs from the class website: SelectionSort, MergeSort.These programs test the specified sorting algorithm on an array whose size is specified by the user, then outputs the amount of time the sorting algorithm takes.
For each sorting program, the main method first prompts for the size of the array to be sorted, then reads the actual integers into the array.Modify the main method of each program so that the values in the array come not from the keyboard, but from calling Math.random() or other random number generator. (Note: Math.random() returns a value of type double in the range 0.0 <= value <= 1.0, but it's easy to scale and convert this to an integer).Also: add a prompt asking the user if the entire sorted array should be output. If the user says no, modify the appropriate loop to output just the first 100 elements, so we can check that they really are sorted.
For large arrays you don’t want to wait while everything prints!Make a table showing the time it takes (in seconds) to perform sorts for each of these array sizes. Do this for both programs.1000
5000
10,000
50,000
100,000
500,000
1,000,000 (this may take several minutes for some programs – patience – but if it takes more than 5 minute on your computer you can terminate it)The smaller sorts will seem to complete instantaneously, while some algorithms will take quite some time as the input size gets large.
Note: when timing a program running on a computer, don’t run any other programs.Turn in your completed table.

Turn in your written results at the beginning of class on the due date.(8 points) Continue the work you began in Lab 1 with these three sorting programs: BubbleSort, InsertionSort, and QuickSort. Modify each program’s main method as before to 1) create an array of random values to sort, and 2) prompt the user about outputting the sorted array values. Run the same trials as before and record the results along with the timings you did for Lab 1:
1000
5000
10,000
50,000
100,000
500,000
1,000,000 (this may take several minutes for some programs – patience)
(2 points) Sketch two graphs showing the data from each table. Plot the timings for BubbleSort, InsertionSort, and SelectionSort on one; MergeSort and QuickSort on the other.
(2 points) Add a second array to be sorted to the main method in the QuickSort class and fill this array with values already in sorted order before calling quickSort. Run the program again on the same array sizes as in Problem 2. Create a new table showing a side-by-side comparison of QuickSort’s performance on random data versus sorted data. If the program should fail for any reason, speculate as to why and determine (within a multiple of 1000) the smallest size array that causes it to fail.
(2+2+2) Determine the runtime complexity of each of the following three methods. Express your answer first exactly, then as a Big-O estimate.
void oddOnes(double[] data) {
for (int i=1; i data[i] = 1;
}
}double findRoots(double a, double b, double c) {
double result = b * b – 4 * a * c;
double disc = Math.sqrt(result);
double[] result = {(-b + disc) / (2 * a), (-b – disc) / (2 * a)};
return result;
}void initPixels(Color[][] pixels, int pixelRows, int pixelCols, Color c) {
int row, col;
for (row = 0; row < pixelRows; row++) {
for (col = 0; col < pixelCols; col++) {
pixels[row][col] = c;
}
}
}
(2 points) The first three orders of algorithms discussed in the text are linear, logarithmic, and quadratic. Which of these three best describes the average-case behavior of BinarySearch?
