Review the Healthy People 2030 Leading Health Indicators (LHIs). Identify the LHI that best matches STIs and transmission through risky sexual behaviors. Critique the objectives and teaching strategies used by the student nurses by responding to the following in a minimum of 175 words:  How do the objectives and teaching strategies address the identified LHI? 

Post a total of 3 substantive responses over 2 separate days for full participation. This includes your initial post and 2 replies to classmates or your faculty member. 
Due Thursday 
Imagine that a group of nursing students wanted to learn more about the health behaviors of adolescents in their community. They decided to have students at the local high school complete a questionnaire about their health behaviors. After the adolescents completed the questionnaire, the nursing students reviewed the responses and tallied the results. They discovered that over half of the respondents engaged in risky sexual behaviors. They reviewed the literature, which stated that sexually transmitted infection (STI) rates in this population are on the rise.
The nursing students decided to educate the adolescents about safe sexual practices and prevention of STI transmission. The goal of the program was to decrease the number of adolescents engaged in risky sexual behaviors. The nursing students developed objectives and teaching strategies for this educational program: 

To instill adolescents with an intrinsic motivation to become aware of their own risky sexual behavior through class discussions and cooperative learning exercises 
To promote safe sexual practices with the adolescents through demonstration of appropriate safe sex practices and inquiry-guided instruction 
To develop students? positive sexual health behaviors through scenario-based case presentations and discussions 

Review the Healthy People 2030 Leading Health Indicators (LHIs). Identify the LHI that best matches STIs and transmission through risky sexual behaviors.
Critique the objectives and teaching strategies used by the student nurses by responding to the following in a minimum of 175 words: 

How do the objectives and teaching strategies address the identified LHI? 
What action by the nursing students illustrates the planning phase of the health planning model? Refer to Figure 7-2, Health Planning Model, in Community Health Planning, Implementation, and Evaluation. 
Which system level is primarily being addressed through the educational program? Refer to Box 7-2, Systems Framework Premises, in?Community Health Planning, Implementation, and Evaluation.

Discuss how new e-commerce tech-giants such as Pinduoduo and Shein could surpass established platforms like Amazon and Alibaba, and assess their potential impact on the future of business

  
In the post-pandemic era, online purchasing has become increasingly popular. Customers now demand a wide variety of new products and on-time delivery within one to two days. Traditional e-commerce platforms such as Amazon and Alibaba are facing fierce competition from fast-growing Chinese tech giants like Pinduoduo (www.temu.com) and Shein (www.shein.com). 
The main competitive advantage for these new entrants lies in the “direct connection” between factories and consumers. They also fully utilize the digital capability to provide more informed choices via the list of recommendations and optimizations based on their network. This assignment requires you to conduct research to compare and analyse traditional e- commerce platforms with new business models such as Pinduoduo and Shein. Your report should be guided by the questions below. 
(a) Discuss how new e-commerce tech-giants such as Pinduoduo and Shein could surpass established platforms like Amazon and Alibaba, and assess their potential impact on the future of business. (40 marks) .
(b) Review two (2) business processes that would benefit from using advanced prescriptive analytics, such as large-scale computation and optimization. Discuss the benefits of applying prescriptive analytics in these areas, along with the possible challenges in their implementation. (60 marks) .

Your neighborhood laundromat is for sale and a friend is considering investing in this business. Your friend has asked for your financial advice regarding this endeavor. For the business alone and no other assets (such as the building and land), the purchase price is $260,000. The net cash flows for the project are $32,000 per year for the next 5 years. The plan is to borrow the money for this investment at 6%. You will need to submit a presentation sharing your recommendation and you must address the following questions: Part A: Calculate the Net Present Value and Payback Period: What is the net present value of this project? Calculate the simple payback period for this project. Your desired payback period is 5 years. How long is the payback period for this project?
