Entrepreneurship

The best way to learn about entrepreneurship is to learn from the experiences of people who have started businesses.

Your assignment is to interview an entrepreneur who has either succeeded or failed and find out the key lessons their experience can teach you.

You should select an entrepreneur who started a business and obtained some form of outside financing (not self-financed / bootstrapped). Ideally, you select an entrepreneur that grew the business to at least $500k in annual revenue. You may interview Georgia Tech alumni, but students and direct family members are not permitted.

You will prepare an article from your interview for upload. Use what you have learned in this class as a framework for perspectives and insights – and focus on the early years of the business. You will be graded on the quality of the article, insights, and key learnings. Some of the questions you’ll be looking to answer in your interview and blog might include:

  • Describe the entrepreneur and the business
  • Why did they start the business?
  • What made them think the business would be feasible / successful?
  • What personal tradeoffs did the entrepreneur have to make to start the business?
  • How was the business financed?
  • Describe the growth and scale of the business
  • What were the biggest obstacles the entrepreneur faced?
  • What was the outcome? What were the key factors for success or failure?
  • What would they have done differently?
  • Describe the key lessons you learned in the interview

Assignment 4-2

Celisteela Moonn met one of SchoolStreet’s clients, Caleb Jamal, to discuss his retirement income.

Moonn plans to invest Caleb’s money in a risky portfolio that might have a long-run low return of 1.0%, medium return of 5.0%, and a high return of 12.0%.

Caleb asked Moonn what would be his annual retirement income in the low, medium, and high return scenarios when saving with a taxable plan, a traditional IRA or 401(k) plan, or a Roth IRA or 401(k) plan?

Caleb provided following info to SchoolStreet:

  • Age 25 years
  • Expect to earn a constant salary of $50,000.
  • Planning to retire at age 65 and expects to live at age 85.
  • Caleb saves at a 10.0% rate.
  • Current tax rate is 18.0% and Caleb expects his retirement years tax rate to be 23.0%.

Using the template provided, calculate Caleb’s annual retirement income for Low Return, Medium Return and Hight Return for:

  • Taxable Investment
  • Traditional IRA or 401(k)
  • Roth IRA or 401(k)

A report on perks of being a wallflower analyzing the main character and psychological concepts regarding development

The purpose of this assignment is to use critical, analytical, and creative thinking to provide an informed discussion on the main character of “Perks of Being a Wallflower” by Stephen Chobsky, by applying the main ideas and concepts of: bronfrenbernners ecological model, importance of biological, social, psychological development during ages 6-14, theories of behaviorism and social cognition and its role in development, cognitive psychology, knowledge construction and processing, Identify risk and resilience in children and how to promote positive youth development, and memory model in developing ages, while problem solving how learning and development can be more accurately depicted through the main character as the premise unfolds. Critically think and provide an informed reaction to the novel based on the information learned in the course including how this information impacts their understanding of the main character’s learning and development. Reactions must be based on the guided questions provided.

Expectations for this assignment:

1.) Critically and analytically discuss a minimum of four applications made between the topics reviewed throughout the semester and the character’s experiences by comprehensively exploring issues, ideas, artifacts, and events before accepting or formulating opinions or conclusions.

2.) Creatively break down the main character’s persona based on these applications including examples of specific times throughout the novel when the author’s portrayal of the character coincides with the knowledge obtained in this course. Students will (1) combine or synthesize existing ideas, images, or expertise in original ways and (2) think, react, and work in imaginative ways, characterized by innovation, divergent thinking, and risk taking.

3.) Problem solve how the author could have altered the premise of the book to incorporate a more accurate depiction of learning and development by providing alternate solutions to the character development and considering how the outcome might differ as a result of this change. Students will design, evaluate, and implement a strategy to achieve the desired goals.

4.) Produce well-organized, well- developed statements that reflect appropriate use of language to clearly present these specific ideas/concepts. The reflection should be a minimum of four pages long (double-spaced, one-inch margins, Time New Romans 12-point font). It must be evident that the guided questions were reflected on for each of the topics discussed and evidence from the material reviewed during the course must be used in support of the reaction and character break down. It is expected that students be working on this assignment throughout the semester. Quality of writing will be assessed. It is expected that grammar, spelling, and punctuation be reviewed prior to submission

Did you implement the intervention as planned? If not, what were the reasons?

Week 10 project

Evaluation of Plan Effectiveness Criteria

Over the past nine weeks, you selected an aggregate and conducted a risk assessment of its health, developed a care plan to address those health risks, planned to implement one intervention in a small group from the aggregate, and considered the effectiveness of the intervention on the health of the small group. It is time now for you to present your final submission of this Capstone project.

There are two parts to this assignment.

Part 1: A 10-15 slide power point presentation addressing the following:

  • A detailed description of the aggregate including strengths and weaknesses
  • A risk assessment of the aggregate
  • Diagnoses based on the risk assessment
  • A detailed care plan for the aggregate
  • A description of at least one intervention that was implemented (or the implementation itself if presented as a power point)

Part 2: In a Microsoft Word document of 3-4 pages formatted in APA style, you will describe the evaluation process of the intervention(s) you implemented.

Include the following in your paper:

An evaluation of the effectiveness of the intervention:

  • Did you implement the intervention as planned? If not, what were the reasons?
  • Interview/measure outcomes for two or three members of your group to determine/measure the effectiveness of the intervention(s).
    • Include transcripts of the interviews with the participants from the group in the appendix of your paper.
  • Finally, compare the projected effectiveness of your plan before implementation with the actual effectiveness after implementation.
    • Are there visible signs of success (for example, reduced health issues)? If yes, describe. If no, describe what signs you would anticipate and rationale for no change.
  • You may want to use the responses to the above two criteria to measure the actual effectiveness of the intervention.

Conclusion

  • Cited at least two scholarly references

On a separate references page, cite all sources using APA format.
