response to Luis Rod

Week 1 Initial post.

Hello Dr. Mills and classmates

It is a great pleasure to start this journey with you. My name is Luis A. Taboada Rodriguez; I am originally from Cuba, where I was awarded the degree of Licentiate in Education at the Higher Pedagogic Institute. I came to The United States 11 years ago. I live in Cape Coral, FL. I graduated with a BSN from NSU at Fort Myers (F.M.) campus in 2018, and I graduated, also from NSU, with an MSN (Nursing Education) last year. Currently, I am a full-time faculty at the F.M. campus. My background as a nurse is in Med-Surgical Telemetry and Operating Room. I see myself as a seasoned NSU professor in five years, and I am anxious to share the Ph.D. program with you. I have a beautiful family, and my backyard is my piece of paradise.

Cause and Effect

What are the major differences between quasi-experimental research, experimental research, and non-experimental research?
One significant difference between the research designs is that non-experimental research does not implement interventions. In addition, the non-experimental research does not establish a direct time order of the cause and effect.

Experimental and Quasi-Experimental research involves an intervention applied to some participants and a comparison group that does not receive the intervention. However, a significant difference between those designs is that quasi-experimental designs lack random selection and random assignment of the study intervention.

Experimental research randomly assigns participants to the group that will receive the intervention or to a comparison group that will not receive the intervention. The experimental design demonstrates that the outcome is related to the intervention. Therefore, it is the most influential research to establish cause and effect order.

Discuss the three major conditions that must be met in order to establish cause and effect.
The three major conditions that must be met in order to establish cause and effect are:

Covariation: The process of establishing a relationship of cause and effect between the variables

Temporal precedence: The process of establishing the cause occurs before the effect

No plausible alternative explanation: The process of establishing that there is some other factor that is causing the outcome

Next, choose one of these conditions and come up with a scenario that would not allow a researcher to meet this condition.
Covariation scenario:

During the COVID 19 pandemic, the shortage of nurses was a reality for many health institutions in the United States. The COVID 19 pandemic was the reason for the nursing shortage across the nation.

This scenario does not allow a researcher to meet the covariation condition since the shortage of nurses in the health system is determined by different factors. For example, high levels of burnout, baby boomers nearing retirement, and federal COVID-19 vaccine mandates may shut down critically needed care (American Nurses Association, 2021). Therefore, the shortage of nurses in the health system is an effect, so it is a variable not conditioned for the pandemic.
