Use the theory that you developed in Week Two. Improve it by using the information you have obtained in the subsequent weeks. Use the Conceptual-Theoretical-Empirical Model (CTE) to link the operational definitions with the empirical indicators with the theoretical concepts and the conceptual model components. Post your revised theory and explain how you would measure the concepts and proposition in a research study.
Week two theory was ..
Choose a clinical situation in your specialty and create a theory from your observations. Report the theory to the class. Use a form that clearly identifies your concepts and propositions such as “psychosocial development (Concept A) progresses through (Proposition) stages (Concept B)”. Identify and define the concepts involved and the proposition between them. For example: a surgical unit nurse may have observed that elevating the head of the bed for an abdominal surgery patient (Concept A) reduces (Proposition) complaints of pain (Concept B). The concepts are head of the bed and pain. The proposition is that changing one will decrease the other. Raising the head of the bed decreases pain. Use current literature to define your concepts. Each concept should have at least two supporting references.
Below is the paper that was written week two please use and post a revised theory and explain how you would measure the proposition in research study
The theory of Evolution by Natural Selection (Concept A) drives (Proposition) the adaptation of species (Concept B).
Darwin’s Theory of Evolution describes how species change with time. This theory rests on two key concepts: Organismal evolution – natural selection (Concept A) and adaptation (Concept B). Natural selection involves a process of evolution characteristic of those species individuals who are in one or many traits superior to other individuals of the same species, are better adapted to effect survival and generate offspring (Frank & Fox, 2020). These lessons are favorable in the population; hence, over generations, they lead to adaptation that involves species evolving modified characteristics that enhance their chance to exist or reproduce in a given habitat.
In this theory, ‘natural selection’ is used differently from normal parlance, where ‘selection’ might imply a ‘choice.’ However, natural selection in the frame of evolutionary biology is not dictated or conscious to any degree (Frank & Fox, 2020). Instead, it paints an inactive process that accrues from openness to selection, in which specific genes grow frequently based on variations in birth and death rates. As for adaptation, there can be misinterpretation. Whereas variation clues to this definition are more or less an individual’s ways of coping with the environmental changes that result in cold weather, evolutionary adaptation is a change that takes generations to occur at the species level (Skinner & Nilsson, 2021). The conscious process reflects a passive process whereby certain genetic traits increase in frequency due to differential survival and reproduction. Adaptation can be misunderstood. While it commonly implies an individual’s response to their environment adapting to colder weather), evolutionary adaptation is a change that occurs at the species level over many generations.
These terms are sometimes misunderstood to convey aspects of intent or individual growth within one life span. For instance, when using a particular term, people may understand that it differs from what the evolutionary theory offers in a specific meaning. For example, some might think that “adaptation’ is when an individual can modify a certain way concerning some difficulty in the organism’s lifespan. It operates on phenotypic variations in the real environment and does not produce new traits whenever the environment needs them, but it eliminates them depending on their ability to reproduce (Skinner & Nilsson, 2021). One can get misinterpretation due to the connotations one associates with the word or phrase in question, thus equating evolution to individual change and personal development.
