Introduction
It is time for us to turn our attention to outlines, organization, and topic choice. This week has two separate assignments that will be submitted. Assignment 1 is the Team Outline Exercise, which involves group work and which will prepare you for Assignment 2, an individual assignment that will start you on the road to completing your Week 7 PowerPoint presentation.

Instructions

Part 1: Outline
This week, you will have an opportunity to work in a team and to put into practice many of the communication strategies about which we are learning. Your instructor has already assigned you to a group of team members. You need to solve a communication business problem outline together by the end of the week. Note:You must engage early in the week so that you have time to work together as a group. Remember, what makes a group a team is a shared common goal, and this team will be no exception. In this case, your shared goal is to create and deliver an A+ solution to a communication business outline.

The following is a list of ideas that were brainstormed in a meeting with your company employees. The company needs to include all these ideas in an all-company presentation, but the list is very disorganized right now. What would be the best way to sort these ideas into some sequence of main points with sub points?

Hints

There are 3 main points, and the rest are sub points.

There is no introduction or conclusion.

Discuss

Your group can be found in the menu under “People.”

You must use the discussion that is setup in the Group Home Page to work on this project.

With your assigned team, unscramble the following statements to create a logical outline for an upcoming business presentation. Use standard outline format as described in your textbook.

1. Ensure that the language is used correctly.

2. Speaker credibility influences how listeners feel about the speaker.

3. Character is the quality of being honest, trustworthy, and showing goodwill.

4. Deliver the speech with confidence.

5. Credibility is an extremely important factor in determining speaker effectiveness.

6. Connect the audience to the topic.

7. Practice your delivery.

8. Verbally cite personal subject knowledge.

9. Present error-free written materials.

0. Credibility has three primary characteristics: the three Cs.

1. Ensure that typographical errors are eliminated.

2. Charisma is the quality of being assertive, confident, and enthusiastic.

3. Speaker credibility influences the listener’s ability to learn or to believe.

4. Demonstrate expertise.

5. Verbally cite expert sources.

6. Connect yourself to the topic.

7. Plan your delivery.

8. Ensure that facts are correct.

9. Competence is the quality of being an expert and being intelligent.

0. Connect with the audience on a personal level.

1. Establish common ground.

2. Credibility is established in four ways.

All team members must collaborate in the group discussion and submit the same version of the outline. Please put the names of your group members who participated in this exercise on the title page under your name. Each member must submit the final group project for their grade.

Part 2: Reflection
As part of your individual submission, reflect on the group process. Was there miscommunication? Were there any listening barriers? How did the group handle it?

You are an assistant to the Special Agent in Charge (SAC) of the Organized Crime Task Force. The SAC has asked you to go over certain witness-related situations that will be testified to in an upcoming trial. The SAC has concerns about some of the witness testimony and is trying to avoid embarrassment by turning in records that may not be usable by the Assistant United States Attorney (AUSA) who is prosecuting the case.

  • Tommy “Two Toes” D’Natalia has a certified public accountant (CPA). He has been using his accountant to wash ill-gotten gains from his racketeering. The SAC has a subpoena for the CPA. D’Natalia is claiming privileged communication with his CPA, and it prohibits the accountant from testifying. 
  • Luigi “the Pipe” Cardone heard through the grapevine that Big Sal Salvatore has been telling everyone how he was told by Frankie “the Lip” Bonnano that Freddie “Fingers” Malone was murdered by his wife Slippery Sally Genovese-Malone. Cardone wants a deal to testify against Slippery Sally. 
  • Lawrence ‘Lucky’ Livorno drove the getaway car for a jewelry store heist. Bertram “Bugsy” Bertoli and Little Carmine D’Angelo went in and robbed the store. During the robbery, Bertoli shot and killed the store owner. D’Angelo and Livorno both want to testify to avoid the death penalty.

For your assignment, complete the following in 3–4 pages:

  • Identify which testimony is hearsay and likely to be inadmissible. 
  • Identify which testimony is privileged communication and which is not. 
  • Identify how the Best Evidence Rule functions in relationship to the witness testimony being proffered.

Module 4 discussion #3

As a recent MBA graduate, you are involved in the project analysis of your company that has three divisions in different business sectors. Your company’s current practice for project analysis is to apply its weighted average cost of capital (WACC) of 12% as a single hurdle rate to all projects across all three divisions.

(a) Criticize your company’s current practice of project evaluation; (b) Discuss the long-term consequences of following this practice including with respect to the riskiness of projects to be accepted and rejected; and (c) What alternative practical criteria would you suggest to your boss for project evaluation? 

Instructions:

Please post your initial response by 23:59 EST Day 3 of the Week, and comments on the posts of at least two classmates by 23:59 EST Due Date.

You must first post your own response directly to the Discussion Topics by Day 3 before accessing other students’ responses. In addition, you should post at least TWO thoughtful and substantive responses to other classmates’ answers/comments by the due date in order to earn 5 points for each Discussion Topic. A mere “Yes, I agree” or “No, I don’t agree” type of responses will not be given any credit.

Additional bonus credit may be given to substantive responses reflecting additional research with sources of information clearly identified as they are particularly valued and enrich our online learning.

Concluding comments on each Discussion Topic will be posted on the Discussion folder after due date.

Think about how you would set the tone and establish a therapeutic relationship with a client. Demonstrate how you would begin your initial meeting with a client. Include the following in your introduction response:

/in /by

Beginning meetings appropriately with clients is essential, since the first impression is often the lasting impression. Generally, the therapeutic assessment interview takes place during the initial meeting between the client and the counselor. During this interview process, the counselor will gather, assess, and analyze pertinent information from the client about their current cognitive, emotional, social, and behavioral experiences, precipitating factors/events, and mental health history, including their family history.

As you may imagine, disclosing this information can be difficult for most people. Beginning a therapeutic relationship can provoke feelings of anxiousness. Clients generally feel anxious to have the problem bringing them to therapy resolved, but they are also anxious about whether there will be a connection with the counselor, and what they can expect from the therapeutic process. To help relieve clients of these anxious feelings, counselors are encouraged to frame the purpose and the process of counseling by setting the tone for the relationship. Counselors can achieve this task by using the initial meeting to establish the therapeutic relationship, setting boundaries, and establishing rules and expectations of the helping context such as confidentiality, crisis management, professional disclosure statement, etc.

Think about how you would set the tone and establish a therapeutic relationship with a client. Demonstrate how you would begin your initial meeting with a client. Include the following in your introduction response:

  • Explanation of the counseling process including the purpose of the therapeutic assessment interview
  • Identify counselor and client expectations (what the client can expect from you and you from them)
  • Explain what will happen during the initial meeting and subsequent sessions
  • Limits of confidentiality
  • Checkout question
  • Door opener

Project Part 2: Gap Analysis Plan and Risk Assessment Methodology

Scenario

After the productive team meeting, Fullsoft’s chief technology officer (CTO) wants further analysis performed and a high-level plan created to mitigate future risks, threats, and vulnerabilities. As part of this request, you and your team members will create a plan for performing a gap analysis, and then research and select an appropriate risk assessment methodology to be used for future reviews of the Fullsoft IT environment.An IT gap analysis may be a formal investigation or an informal survey of an organization’s overall IT security. The first step of a gap analysis is to compose clear objectives and goals concerning an organization’s IT security. For each objective or goal, the person performing the analysis must gather information about the environment, determine the present status, and identify what must be changed to achieve goals. The analysis most often reveals gaps in security between “where you are” and “where you want to be.”Two popular risk assessment methodologies are NIST SP 800-30 revision 1, Guide for Conducting Risk Assessments, and Operationally Critical Threat, Asset, and Vulnerability Evaluation (OCTAVE). Your focus will be on the OCTAVE Allegro version, which is a more concise version of OCTAVE. When reviewing the methodologies, consider the following:

  • Which features or factors of each methodology are most important and relevant to Fullsoft?
  • Which methodology is easier to follow?
  • Which methodology appears to require fewer resources, such as time and staff, but still provides for a thorough assessment?

Tasks

  • Create a high-level plan to perform a gap analysis.
  • Review the following two risk assessment methodologies:
    • NIST SP 800-30 rev. 1, Guide for Conducting Risk Assessments (formerly titled ” Risk Management Guide for Information Technology Systems”)
    • Operationally Critical Threat, Asset, and Vulnerability Evaluation (OCTAVE), Allegro version
  • Create a report that includes the gap analysis plan, a brief description of each risk assessment methodology, a recommendation for which methodology Fullsoft should follow, and justification for your choice.

Required Resources

  • Textbook for this course
  • Internet access
  • Additional websites for research

Submission Requirements

  • Format: Microsoft Word or compatible
  • Font: APA Format
  • Citation Style: APA Format
  • Submit in the Group Project Part 2Assignment
  • Name the document Group-project-part-2
  • Length: 5-6 pages plus citation page

You are encouraged to respond creatively, but you should cite credible sources to support your work.

Self-Assessment Checklist

  • I created a plan for performing a gap analysis of the IT environment.
  • I evaluated and selected a risk assessment methodology.
  • I summarized each methodology, recommended which methodology Fullsoft should follow, and provided justification for my choice.
  • I conducted adequate independent research for this part of the project.
  • I followed the submission guidelines.

Evidence-Based Practice Guideline

Write a fully developed and detailed APA essay addressing each of the following points/questions. There is no required word count; be sure to completely answer all the questions for each question in detail. Separate each section in your paper with a clear heading that allows your professor to know which bullet you are addressing in that section of your paper. Sources are not required; however, if sources are used make sure to cite using the APA writing style for the essay and complete a reference page. The cover page is required. Review the rubric criteria for this assignment.

Utilize the databases identified in the text to locate an Evidence-Based Practice Guideline, related to your topic identified in Module 1. Perform a rapid critical appraisal of the Evidence-Based Guideline by answering the following questions in APA format. All questions should be answered in detail and explanations offered according to guideline content when applicable.

  • Who were the guideline developers?
  • Were the developers of the guideline representative of key stakeholders in this specialty (inter-disciplinary)?
  • Who funded the guideline development?  
  • Were any of the guideline developers funded researchers of the reviewed studies?
  • Did the team have a valid development strategy?
  • Was an explicit (how decisions were made), sensible, and impartial process used to identify, select, and combine evidence?
  • Did its developers carry out comprehensive, reproducible literature review within the past 12 months of its publication/revision?
  • Were all important options and outcomes considered?
  • Is each recommendation in the guideline tagged by the level/strength of evidence upon which it is based and linked to the scientific evidence?
  • Do the guidelines make explicit recommendations (reflecting value judgments about the outcomes)?
  • Has the guideline been subjected to peer review and testing?
  • Is the intent of use provided (i.e. national, regional, local)?
  • Are the recommendations clinically relevant?
  • Will the recommendations help me in caring for my patients?
  • Are the recommendations practical/feasible? Are resources (people and equipment) available?

In responses to Traci, Nathan, Krista, and Jennifer indicate what you think it is about their examples that clarify the concept “mean of the sampling distribution.” The concept is abstract, but how do their examples make it concrete and more understandable? As an alternative, you could explain how the concept of a sampling distribution pertains to inferential statistics.

Traci post

The mean of a sampling distribution is a distribution created by every possible mean from every possible sample. When the samples used to develop each mean of the distribution are large enough, then the sampling distribution of the mean of any independent random sample will be normally distributed The larger the sample, the more likely it will have that normal bell shaped curve. This method can be useful because it can determine how accurate my chosen sample mean is from all other possible means.

Sampling Distribution Example:

Lets say I wanted to know the average birth weight of a new born baby, I think I would randomly select recorded birth weights of 50 newborns at a hospital. I would calculate the mean of birth weights for the 50 babies. I now have my first mean, let’s say I repeat the process across the nation obtaining birth weight records for newborns at 100 different hospitals, I now have 100 sets of 50 NB birth weights and 100 different means which make up the sampling distribution. To get the mean of the sampling distribution, I’d calculate the mean of all 100 means from the 100 sets of 50.

Nathan post

  A sampling distribution is simply what is produced when all of the sample statistics are distributed from all necessary samples, regardless of whether or not there is a variance in size. The process of distribution, in this case, is known as the distribution of sample means, since it is used to find the mean of all possible samples (Bennett, Briggs & Triola, 2016, 270). A perfect example of can take place in a pediatrician’s office, where growth charts are utilized to monitor how a child is developing and whether or not they are sustaining a healthy BMI. A pediatrician alone may see a hundred patients, but what if that pediatrician was just a dime in a dozen and worked alongside many other pediatricians. Say, 100? Well, those pediatricians also see approximately a hundred patients too, and it just so happens that every doctor has reached their capacity. Each pediatrician also has a hundred growth charts. Therefore, the hundred growth charts each pediatrician possesses will produce an individual mean. If one were to put all of their means together, it would produce a sampling distribution, and from there, him or her can use the process of “distribution of sample means” to find the mean BMI of every single child in this obnoxiously large pediatrician’s office. 

Krista post

The mean of a sampling distribution is a distribution created by every possible mean from every possible sample.

For example, if I wanted to know the average amount of children per household in North America, I could randomly select 100 households within a state to poll. I would calculate the mean of the number of children per household. Now I would repeat this process in each of the 50 states, giving 50 sets of a 100-household polling, which gives 50 different means to create the sampling distribution. The mean of the sampling distribution would be the mean of all 50 means from the 50 sets of 100.

Jennifer post

A sampling distribution is a probability distribution of a statistic obtained through many samples drawn from a specific population. The sampling distribution of a given population is the distribution of frequencies of a range of different outcomes that could possibly occur for a statistic of a population. The number of observations in a population, the number of observations in a sample and the procedure used to draw the sample sets determine the variability of a sampling distribution. The standard deviation of a sampling distribution is called the standard error. While the mean of a sampling distribution is equal to the mean of the population, the standard error depends on the standard deviation of the population, the size of the population and the size of the sample. Knowing how spread apart the mean of each of the sample sets are from each other and from the population mean will give an indication of how close the sample mean is to the population mean. The standard error of the sampling distribution decreases as the sample size increases.

Example: The Can Equity Mortgage company, has the mean age of mortgage applicants in the city of Toronto is 37 years of age. Then assume that the standard deviation if 6 years. The find the mean and standard deviation of the sampling distribution of the sample mean for the following sample sizes: (a) 4, (b) 100, (c) 255 μx = μ = 37

(a) n = 4. Then σX−−=σ/n−−√=6/4–√=3.

(b) n = 100. Then σX−−=σ/n−−√=6/100–√=0.6

(c) n = 225. Then σX−−=σ/n−−√=6/225–√=0.4.
