ADVANCED SOCIAL NETWORK ANALYSIS

Instructions

Please read through and carefully follow these instructions and try to sketch an outline for a report.

The data set I’ve chosen is Lazega Law firm: An expanded version of the dataset for lawyers in a New England law firm. This has 71 lawyers, their advice, friendship, and co-worker ties as well as a number of attributes. I will upload the dataset separately.

Instructions

Choose one of the themes from the list below which you feel most comfortable with:

·         Degree-based effects

·         Closure and connectivity

·         Cohesion and embeddedness

·         Balance, homophily and transitivity                                              

and write a 3000 word (upper limit) report that addresses this topic from theperspectives of

– relevant network-related theory
– use of an empirical Data set
– appraisal of how theory, research questions and data fit together and support each other

Guidelines

You a meant to demonstrate that you can tie together some substantive theories with an empirical analysis, where the theories have been expressed in appropriate research questions, and subsequently draw conclusions about the extent to which data support your research questions. The report MUST include an empirical analysis. This does not have to be very advanced but you must employ some manner of quantitative evaluation; e.g. comparing some measure against a null-distribution of graphs (graphically or by using statistics); or fit a model (ERGM, SAOM or any other model).

The minimal requirement is that you form one research question based on theory that you then express in terms of prevalence of subgraphs or a particular structural pattern in data, and that you furthermore explore and test this on some data set.

Things you must do in your analysis of the dataset:

1. setting the number of nodes/actors

2. calculating the number of ties and density

3. calculating the number of Mutual, Assymetric, and Null Dyads

4. calculating the triad census

5. calculating the degree distributions

·         When presenting and analysing the network make sure that you define the nodes, ties, and context, properly.

·         Make sure you understand what the data set is and able to explain how it is collected.

Create an ERD for the following scenario.

A small company ABC wants a database to keep track of internal company information. Â  Given the following information create an ERD. The ABC Company has several departments and several employees. A division operates many departments but each department is operated by only one division. Most employees reside in a single department however, the company has “rovers” that aren’t assigned any department. Employees are assigned to projects along with other employees. If a project doesn’t have any employees assigned it is cancelled. Each division has a single manager and each department has a single manager. Employees cannot manage more than one division or department.

Here is a link to follow but create your own.

Scenario:

Schools, colleges, as well as, private industry, can create policies on academic integrity, yet enforcement of these policies are totally in the hands of the professors/teacher. The teacher may elect to choose to ignore certain types of cheating and students may even challenge the instructor when accused of cheating, if the policy was not clearly stated in the course syllabus. A course syllabus is the contract between the instructor and student. Policies on academic integrity that convey what actions will not be tolerated within the course should be clearly stated in the syllabus. It is an instructor’s responsibility to pass deliver these policies to the students.

Directions:

I need help using the attached resources to create my own  two page policy that completely addresses the issues of plagiarism, academic integrity, and. Make sure to add details that adheres to all of the aspects of online cheating, including the penalties and/or consequences for breaking these rules/policies. 

Must use 4 to 5 currently SCHOLARLY APA style refeferences/resources.

• 2.1 What are the essential ingredients of a symmetric cipher?
• 2.2 What are the two basic functions used in encryption algorithms?
• 2.3 How many keys are required for two people to communicate via a symmetric cipher?
• 2.4 What is the difference between a block cipher and a stream cipher?
• 2.5 What are the two general approaches to attacking a cipher?
• 2.6 Why do some block cipher modes of operation only use encryption while others use both encryption and decryption?
• 2.7 What is triple encryption?
• 2.8 Why is the middle portion of 3DES a decryption rather than an encryption?

———————————————————————————————-

 In no less than 250 words, explain the difference between symmetric and asymmetric encryption.  Which one is better and why? 

———————————————————————————————-

Any data that is sensitive or critical for business or military purposes should be encrypted. But what does it mean to be encrypted. What does encrypted data look like? In this lab we will look at data which is unencrypted and data that is encrypted. We will use a tool called GNS3 to simulate two routers that are connected via a point-to-point link. We will run data through this link while looking at the packets going through it. The tool we will use to view the data is Wireshark which is probably the most important tool we as network engineers have in our toolbelt. Let’s answer the following questions as we go through the lab.

Ÿ 1. What is the cleartext data that is being sent in the ping between the two PCs? _____________________

Ÿ 2. What is the protocol used for the ping utility? ____________________

Ÿ 3. How many ping messages do you see? _____________________ Why? ________________________________________________________________________

Ÿ 4. Is this data encrypted or unencrypted? _____________________________

Ÿ 5. Now let’s make a change in the router. What types of messages do you see now? Does it look the same as the messages we saw before we made the change to the router? ________________________

Ÿ 6. What protocol do you see now? ____________________

Ÿ 7. Are you still able to see the source and destination MAC address? __________What layer is this you are looking at the MAC address in? _____________

Ÿ 8. Are you still able to see the source and destination IP address? __________What layer is this you are looking at the IP address in? _____________ 

Ÿ 9. Can you see the cleartext data you saw before? ____________________________

Ÿ 10. Explain the ESP protocol. Does what we see in Wireshark make sense? Write a paragraph answering these two questions.
