Compare node 0’s collision counts in these three scenarios and the other graph to compare the received traffi c from the three scenarios.

Explain the graph we received in the simulation that shows the relationship between the received (throughput) and sent (load) packets. Why does the throughput drop when the load is either very low or very high?

2. Create three duplicates of the simulation scenario implemented in this lab. Name these scenarios Coax_Q2a, Coax_Q2b, and Coax_Q2c. Set the Interarrival Time attribute of the Packet Generation Arguments for all nodes in the new scenarios as follows: ❍ Coax_Q2a scenario: exponential(0.1) ❍ Coax_Q2b scenario: exponential(0.05) ❍ Coax_Q2c scenario: exponential(0.025) In all these new scenarios, open the Confi gure Simulation dialog box, and from the Object Attributes, delete the multiple-value attribute (the only attribute shown in the list). Choose the following statistic for node 0: Ethcoax · Collision Count. Make sure that the following global statistic is chosen: Global Statistics · Traffi c Sink · Traffi c Received (packet/sec). (Refer to the “Choose the Statistics” section in the lab.) Run the simulation for all three new scenarios. Get two graphs: one to compare node 0’s collision counts in these three scenarios and the other graph to compare the received traffi c from the three scenarios. Explain the graphs and comment on the results. ( Note: To compare results you need to select

3. To study the effect of the number of stations on Ethernet segment performance, create a duplicate of the Coax_Q2c scenario, which you created in Exercise 2. Name the new scenario Coax_Q3. In the new scenario, remove the odd-numbered nodes, a total of 15 nodes (node 1, node 3, …, and node 29). Run the simulation for the new scenario. Create a graph that compares node 0’s collision counts in scenarios Coax_Q2c and Coax_Q3. Explain the graph and comment on the results.

4. In the simulation, a packet size of 1024 bytes is used. ( Note: Each Ethernet packet can contain up to 1500 bytes of data.) To study the effect of the packet size on the throughput of the created Ethernet network, create a duplicate of the Coax_Q2c scenario, which you created in Exercise 2. Name the new scenario Coax_Q4. In the new scenario, use a packet size of 512 bytes (for all nodes). For both Coax_Q2c and Coax_Q4 scenarios, choose the following global statistic: Global Statistics · Traffi c Sink · Traffi c Received (bits/sec). Rerun the simulation of Coax_Q2c and Coax_Q4 scenarios. Create the following graphs and explain them:

a. A graph that compares the throughput as packets per second in Coax_Q2c and Coax_Q4 scenarios

b. A graph that compares the throughput as bits per second in Coax_Q2c and Coax_Q4 scenarios

What conclusions can you make about the issue of male and female pay equality? Are all of the results consistent?

Measurement issues. Data, even numerically coded variables, can be one of 4 levels -nominal, ordinal, interval, or ratio. It is important to identify which level a variable is, as this impact the kind of analysis we can do with the data. For example, descriptive statistics such as means can only be done on interval or ratio level data. Please list under each label, the variables in our data set that belong in each group.

Nominal Ordinal Interval Ratio

b. For each variable that you did not call ratio, why did you make that decision?

2. The first step in analyzing data sets is to find some summary descriptive statistics for key variables. For salary, compa, age, performance rating, and service; find the mean, standard deviation, and range for 3 groups: overall sample, Females, and Males. You can use either the Data Analysis Descriptive Statistics tool or the Fx =average and =stdev functions. (the range must be found using the difference between the =max and =min functions with Fx) functions.

Note: Place data to the right, if you use Descriptive statistics, place that to the right as well.

2. nclude an example seen in the workplace, in the news, etc. that relates to real-life situations.

Describe some events which are affecting equilibrium in that market, how they are affecting the market’s supply or demand.

Think about a real-world situation you can explain using the supply and demand model, and write about it. This example may be based on your own personal experience, your employment, or on something you’ve read. It should be based on actual events, and not fictional (like the examples we used in class).

In your writing, first define the market you are interested in, and briefly explain what is behind the supply and demand curves in that market. Remember, “market” generally refers to something broader than a specific brand (e.g., new cars, not Ford cars). Then, describe some events which are affecting equilibrium in that market, how they are affecting the market’s supply or demand, and how the equilibrium price and quantity are changed as a result. Your analysis should agree with reality: if the model predicts prices increasing, is that we actually observe? Include at least one supply and demand graph to illustrate your text.

Type, and pay attention to the clarity, organization, and correctness of your writing. The graph may be hand drawn and on a separate page, but make sure your text makes clear what the graph is illuminating. If you base any of your work on something you’ve read, include a citation of your sources.

Describe how the child progressed from rolling over, to sitting, standing, and walking.

In this assignment, you will explore and apply theories of development to your personal experiences.

Background

Understanding theories of development is key in psychology. All people proceed through specific areas of change and growth in key areas as they go through life. Whatever path we take in life, understanding theories of development will assist us in motivating and guiding others, as well as understanding ourselves.

Instructions

Apply the theories of development to your personal life experience by answeringeach of the following questions.

Jean Piaget’s Stage Theory of Cognitive Development: At what age do you feel you entered the stage of Formal Operational Thought? Explain the stage briefly and then focus on providing examples of ways your thinking has shifted to indicate you have developed into this stage of reasoning. (For instance, provide an example of how your views of justice or morality have shifted as you’ve matured.)

Developmental Stage Theory of Erik Erikson: Choose one stage from Erikson’s Developmental Stage Theory and apply it to your own life. Explain the stage, age that it occurs, and how the central challenge of that stage played out in your life. What was the outcome of this stage for you? Did anything happen in your life prior to that stage that affected the outcome? How does the outcome from that stage affect how you are today? Provide specific details that demonstrate your understanding of the stage you choose.

Lawrence Kohlberg’s Theory of Moral Development: Considering the moral or ethical decisions that you have made in your life, describe one decision you made based on one of the three levels of moral development. Be sure to clearly explain the level of moral development and clearly identify the underlying ethical reasoning behind your decision. (For instance, you may explain a decision you made based on Preconventional morality when you were a child, or you may focus on a decision you made from a higher level of development as an adult.)

Developmental Milestones: Motor Development. The unfolding of biological potential is known as “maturation.” Motor skill development in babies is mostly controlled by the process of maturation. Think about a child that you have known (yourself, your own child, a friend or family member). Describe how the child progressed from rolling over, to sitting, standing, and walking. At what age did each milestone occur? Did the development occur in a “typical” sequence based on what you’ve learned in your text? Is there anything that occurred in the child’s environment that either delayed motor development or facilitated it? What is the difference between “maturation” and “learning,” based on your readings and observation?

Your response should be a 3–4-page Microsoft Word document written in a clear, concise, and organized manner. Be sure to demonstrate ethical scholarship in accurate representation and attribution of sources (i.e., APA); and display accurate spelling, grammar, and punctuation.

Your supervisor informs you that each criminal justice agency in your community has to develop a new crime fighting strategy for the coming fiscal year that must be based on a crime causation explanation to be presented to the city council for funding your department. Using the library and other available resources, prepare a brief summary of a policy linked to a theory that you would proposed.

In your response, please address the following:

The purpose of the policy
The theory guiding your policy
Anticipated benefits
Benefits and disadvantages of your policy

When commenting to other students’ posts, consider the following:

Do you agree with the viability of their policy?
Do you see any additional advantages or disadvantages to their policy

Identify at least 2 challenges to the selected biometric, In other words, what are the limitations of its use?

Biometrics continues to be an emerging field, and its use continues to evolve in criminal investigations. As you know, fingerprints are considered to be scientifically valid evidence that has been accepted by various courts. However, many of these new technologies have not had enough time to be scientifically recognized as valid means of identifying somebody for criminal trial related purposes. With this in mind, examine some of the challenges with the lesser accurate forms of biometrics, including facial recognition, voice recognition (voice stress analysis), or signature recognition. Prepare a 3–5 page paper that addresses the following questions:

Select 1 of the above listed less accurate forms of biometrics and summarize the science behind it (i.e., how it works) and how it can be used in criminal investigations.
Identify at least 2 challenges to the selected biometric. In other words, what are the limitations of its use?
Provide a hypothetical example of the selected biometric being used in a criminal investigation.
