Some individuals are more adapted to breath in low oxygen concentration regions. For instance, people living in high altitude areas such as the Himalayas have adaptations that ensure their survival. Their blood can carry and hold oxygen in low oxygen areas. Similarly, some individuals can hold breath underwater for a longer time than others. I would, therefore, like to research on the adaptations that enable such individuals to hold breath underwater. The epidemiological side of the research is that particular people around the world are more adapted; hence, their experience will be vital in the study. Studies indicate that the Bajau (Sea Nomads) people spend about 60% of their workday underwater (Ilardo, Moltke, et al., 2018). Research findings indicate that the Bajau people have spleens that are 50% larger than those of the land-based individuals. The spleens act as reservoirs for oxygenated blood, and when the spleen is squeezed during a dive reflex, the blood facilitates the long breathless dives. Also, studies indicate that the Bajau people have a genetic component that affects their spleen size (Ilardo, Moltke, et al., 2018). The enlarged spleen size makes the Bajau people to be adapted to the underwater environment. I would, therefore, like to carry out scientific research to verify these conclusions.
The philosophical orientation that reflects my worldview is postpositivism. I hold a deterministic philosophy that seeks to identify the cause that influences the results. Postpositivism supports scientific research as the basis of verifying a theory. For instance, the research findings on Bajau people require experimental research data for verification. The orientation involves the development of numerical measures and empirical observations to test and verify theories for a better understanding of the world (Phillips & Burbules, 2000). It also aims to reduce ideas into a discrete set that enables testing of various variables of the hypothesis. As such, the postpositivism worldview is more aligned with a quantitative research method that allows for the collection of data to verify a hypothesis (Tuli, 2010). The philosophical orientation has both epistemological and ontological assumptions. The epistemological assumption is that knowledge is speculative; thus, it is difficult to find the absolute truth. It seeks to investigate the difference between opinion and belief by being an essential part of it. It is, therefore, necessary to be objective when conducting research and examine the conclusions to avoid bias. The validity of the data is crucial; hence, the quantitative research aspect of the assumption. The ontological assumption seeks to address the question of what we are studying and if it exists. The data, evidence, and coherent considerations aim to address this vital aspect of the research.
