(1). EDITORIAL EXTRACTION

Select any visualisation/infographic and looking at any individual chart included. Try to extract and write down in language terms what this chart shows across the angle, the framing, and (where relevant) the focus?

Does it feel that the definition you have arrived at is consistent with the aims/claims of the chart as it is published? In other words does the chart show and include what you think it is actually supposed to be doing or is there a disconnect?

Describe the pros and cons of online shopping. 

Include examples of online shopping sites, both businesses and private consumer to consumer sites as well as any experiences you’ve had buying or selling online. 

Using the below image represent this family using a graph structure. The graph needs to be a weighted graph. The weights will constitute the types of relationships, I recommend using some kind mapping between numbers and strings to represent the relationships. When adding family members to the graph, this can be done programmatically for the provided family members within the description file.

Additionally,

• I also want there to be an interface in which a user can create a new family member and add them to the tree.
• This can be a simple CLI where the user provides a name, gender, and age to create a person.
• Then another simple CLI where they select which member of the family, they want the original relationship to be with and what kind of relationship it should be.
• Finally, they can edit the family member using another CLI and selecting the family member they wish to edit, the operation they wish to perform (edit name, edit age, edit relationship), and then add new relationship between family members which can call a function that you create in order to add the original relationship.

Finally, make data assertions within the FamilyTree class that enforce certain “rules” that exist in a typical human family. An example would be a person should not have any kind of relationship to itself (a person cannot marry themselves, a person cannot be their own brother, sister, father, mother, etc.). There should be at least 3 data assertions. These should exist as part of the family tree, not as part of the graph.

As a hint, for a successful design:

I would recommend using layers of abstraction. Your graph class is the backing structure to the family tree class. Your family tree should implement methods that interface with the graph class, i.e. add_family_member() should call the constructor to create a node and then call a function within the graph class to add a node to the graph. Then using the relationships function parameter, you can add edges to the graph between the new nodes and the existing nodes. The family tree should be what enforces what relationships can exist through the data assertions, the graph does not care about what relationships are made between family members. Your functions that the user would interface with would be greatly reduced compared to the total number of methods within the classes themselves. The user should be able to add, remove, and modify family members and that’s about it. Therefore, those should be your function calls.

Should an individual invest in digital currencies? Why or why not? Explain your reasoning.

In this scenario, hackers launch cyber-attacks that affect several parts of the nation’s financial infrastructure over the course of several weeks. Specifically, sensitive credit card processing facilities are hacked and numbers are released to the Internet, causing 120 million cards to be canceled; automated teller machines (ATMs) fail nearly simultaneously across the nation; major companies report payroll checks are not being received by workers; and several large pension and mutual fund companies have computer malfunctions so severe that they are unable to operate for more than a week.

Do the exercises below.

questions based on chapter 2 exercises:

(1) based on exercise 22

A) Describe how to map values from the interval [-1,1] to the interval [0,1].  

B) Consider two time series as two sets on numbers: e.g. S1 = {3, 5, 7, 8 , .., 4, 7} and S2 = {5, 5, 8 , .., 9, 7}. You need to come up with 2 sets, each having 100 elements. You can make them random if you like.

1) Normalize each set in range [0,1].

2) Find the probabilities of S2 in the ranges [0,0.1], (0.1,0.2], (0.2,0.3], .., (0.9,1] when S1 are in the same ranges [0,0.1], (0.1,0.2], (0.2,0.3], .., (0.9,1] respectively,  (find probability of value of S2 in the range, given the value of S1 is in the same range).

questions based on chapter 4 exercises:

(2) based on exercise 12

Let X be a binomial random variable with mean N * p and variance N * p * (1−p).

A) Show that the ratio X/N also has a binomial distribution

B) Show that the ratio X/N also has mean p

C) Show that the ratio X/N also has variance p * (1 − p) / N

questions based on chapter 5 exercises:

(3) based on exercise 6 

A) Suppose the fraction of undergraduate students who smoke is 15% and the fraction of graduate students who smoke is 23%. If one-fifth of the college students are graduate students and the rest are undergraduates, what is the probability that a student who smokes is a graduate student?

B) Given the information in part (a), is a randomly chosen college student more likely to be a graduate or undergraduate student?

C) Repeat part (b) assuming that the student is a smoker.

D) Suppose 30% of the graduate students live in a dorm but only l0% of the undergraduate students live in a dorm. If a student smokes and lives in the dorm, is he or she more likely to be a graduate or undergraduate student? You can assume independence between students who live in a dorm and those who smoke.

Week 4 Written Assignment

This week’s journal articles focus on transformational leadership and knowledge and knowledge sharing within an organization, please review these concepts and answer the following questions:

1. How do trustworthy and ethical leaders enhance knowledge sharing in organizations?  How does this impact the rate of information technology implementations?  How does this impact data management within organizations? 
2. How does servant leadership assist with transferring knowledge in an organization?
3. When thinking about data analytics, how does transformational leadership assist with building good data structures?

Be sure to use the UC Library for scholarly research. Google Scholar is also a great source for research.  Please be sure that journal articles are peer-reviewed and are published within the last five years.

The paper should meet the following requirements:

• 4 pages in length (not including title page or references)
• APA guidelines must be followed.  The paper must include a cover page, an introduction, a body with fully developed content, and a conclusion.
• A minimum of five peer-reviewed journal articles.

The writing should be clear and concise.  Headings should be used to transition thoughts.  Don’t forget that the grade also includes the quality of writing.
