Each year, Alibaba handles more than 80% of China’s e-commerce business. The company now operates in 190 countries (only 196 countries and 61 territories exist in the world). Moving forward, the vision for Alibaba sounds simple: Bring in non-Chinese brands to the Chinese market and expand products to customers outside of China’s borders. Do you think this global strategy is viable?

The large-scale product selection that can be found on the Alibaba platforms has resulted in some 15 billion products being sold annually and 15 million packages being shipped daily (compared with 5 billion items on Amazon and 3 million packages per day). This puts tremendous pressure on global supply chains. Can the supply chains continuously facilitate the increased demand that we as customers place on the global supply chain systems?

1. Download KNIME (Links to an external site.) to complete this assignment.
2. Before you start working on this assignment, study the KNIME Quickstart Guide (Links to an external site.) to get familiar with the tool.
3. Download the file adult.csv available in the data folder on the KNIME Hub. The data are provided by the UCI Machine Learning Repository.

Part 1:

1. Create a new workflow and name it as: your_firstname_lastname_decision_tree.
2. In your workflow, train a Decision Tree to predict whether or not a person earns more than $50K per year:
   • Partition the dataset into a training set (75%) and a test set (25%). In your Partitioning node, apply stratified sampling option on the income column.
   • Train a Decision Tree model on the training set, and apply the model to the test set.
3. Use the Scorer node to evaluate the accuracy of the model.
4. Change the label of each node from the default (such as “Node 1”) to a brief description (e.g. “Read data from adults.csv”).
5. Try out other parameter settings to get a higher accuracy. For example, change the quality measure, pruning method, or minimum number of records.
6. When you are satisfied, export your workflow project and change the file name to include your full name. e.g. “potter_henry_decision_tree.knwf.”

Part 2:

1. Research and prepare answers to the following questions in a Word or pdf file:
   • What’s the purpose of applying stratified sampling option on the income column?
   • What’s the purpose of pruning and minimum number of records?
   • How did you changed parameter settings to get a higher accuracy?

Watch the Introduction to Databases video (https://www.youtube.com/watch?v=D-k-h0GuFmE ) by Dr. Jennifer Widom of Stanford University and respond to the items in Part 1.   Feel free to pause the video to respond to the items and re-watch segments as necessary.  Alternatively, you may prefer to view the presentation once through and then again to complete the assignment.  The presentation is 13 minutes long.

Part 2 of the assignment is not specifically related to the video, but will require some additional investigation and research.

Note that this presentation is part of a database course for computer science students at Stanford University.  When Dr. Widom states ‘in this course we will cover’ or that ‘we will cover’ a given topic in greater detail later in the course, she is referring to her course, not ours.

Information Technology and Organizational Learning Assignment:

• Chapter 9 – Review the section on Establishing a Security Culture. Review the methods to reduce the chances of a cyber threat noted in the textbook. Research other peer-reviewed sources and discuss additional methods to reduce cyber attacks within an organization.
• Chapter 10 – Review the section on the IT leader in the digital transformation era. Address how IT professionals, and especially leaders, must transform their thinking to adapt to the constantly changing organizational climate. What methods or resources can leaders use to enhance their attitudes toward change?

The above submission should be two pages in length (one page for each question) and adhere to APA formatting standards.

**Remember the APA cover page and the references do not count towards the page length

**at least two scholarly or practitioner sources

Note: plagiarism check required, APA7 format, include References, within 8hrs

Two (2) high ranking managers of Anrun Corp. know that the company’s revenue is rapidly declining. However, at a recent shareholder meeting, they tell the shareholders to expect record profits in the next quarter.

Excel_5G_Sports_Programs

Project Description:

In this project, you will create a worksheet for Sandy Chase, Assistant Director of Athletics, with data that has been sorted, filtered, and grouped and that analyzes sports programs at Laurel College.

Open   the Excel workbook Student_Excel_5G_Sports_Programs.xlsx   downloaded with   this project.

Display the Valley-Park-West   worksheet. Select the range A1:J40, insert a table, and then display the   Table Styles gallery. In the third row, apply the fourth style or choose   another style.

Sort the table on the Campus   column using a Custom List in the following order: Valley, Park, West. (Mac   users, create the custom list in the Excel, Preferences, Custom Lists dialog   box.) Add a second level sort by Sport Group and a third level sort by   Program Name both in ascending order.

Display the Sports Season   Comparison worksheet. Copy the range A6:G7, paste it in cell A1, and then   change the title in cell A1 to Criteria. Select the range A2:G3, and then name this range Criteria.

Copy the range A1:G2, and then   Paste the copied range in cell A36. Change the title in cell A36 to Fall-Summer   Sports Season.   Name the range A37:G37 Extract and then name the range A7:G34 Database.

Create an advanced filter that   will place in the Extract area the records from the Database range in which Fall is the primary season and Summer is the secondary season.

Display the Stipends by Group   worksheet. Sort the data in ascending order first by Group and then by Coach   Stipend.

Apply subtotals to the Coach   Stipend column at each change in Group. AutoFit columns C:D and then collapse   the outline so that the Level 2 summary information is displayed.

On the Valley-Park-West   worksheet, in cell J1, insert a Hyperlink to the file you downloaded with   this project, e05G_Coach_Information.   Display the ScreenTip, type Click here for contact information and then test your hyperlink.   Close the e05G_Coach_Information   file.

Select all three worksheets.   Insert a footer in the left section that includes the file name, and in the   right section, insert the Sheet Name. Set the Width and Height to 1 page, and   Center the worksheets horizontally. Change the Theme to Slice, and then change   the Fonts theme to Corbel.

Display the workbook Properties,   and then as the Tags, type sports programs As the Subject, type your course name and section   number. Be sure your name displays as the Author.

Save and close the file, and   then submit for grading.

The control of the serialization of memory management is difficult in a “Virtual Memory” and especially when “Virtual Machines” are included. Discuss how an operating system manages “computer memory in both single and multiple OS instances”. Add discussions about how some of the problems have been addressing including respective advantages and disadvantages.

 Please respond to the below text in 100 words or more.

While  researching the topic I learned that selective statements are used for  decision making in the code. Selective statements use lines such as “if”  or “else”. An example of this would be to find if a number is greater  than or equal to a number in an equation. I wrote the following simple  code in Eclipse to help demonstrate this.

int A=4;

if (A<3||A>3) {

System.out.println(“A is not equal to 3”);

}else {System.out.println(“A is equal to 3”);

The code would see the number 4 and be able to tell you that it is not equal to 3.

Repetitive  statements are different from selective statements as they are used to  repeat the code or are used for looping if they are within the  parameters you have set. Repetitive statements use the “for statement”,  “while statement”, and “do-while statement”.

Using math again for my examples I have used the following codes to show how these statements work.

for (int x = 0; x*2 < 15; x++)

{

System.out.println(x);

In  this example I am using the for statement. Essentially, I am asking the  code to give me all the numbers that can be multiplied by 2 without  going over 15. It will start with 0 and go up one number until 7, as any  integer above 7 would be greater than 15. 

int x = 0;

while (x <= 200)

{

System.out.println(x);

x = x+50;

The  while statement is used here to tell the code that it wants it to  repeat adding 50, while starting at 0 while not going over 200.

All assignments need to be DONE on CODEGRADE.
