In order to answer to the research question that “why some people are not using bednets?”, I would like to use qualitative research by in-dept interview method with a group of key informant who did use and didn’t use bednet.

New technologies might have more benefits and usefulness compare to existing technologies. However, the change can be step-by-step, start with small pilot setting and then scale up to the whole organization when we see the good results and good practices in real life. This method can allow us to compare results and performance both new and old…[Read more]

I think social and peer influence may play an important role on an individuals’ perceived ease of use or perceived usefulness of a new technology. I also think ecological models which recognize multiple levels of influence on human behaviors, including: Intrapersonal/individual factors, which influence behavior such as knowledge, attitudes, b…[Read more]

Efficacy can be defined as the performance of an intervention under ideal and controlled circumstances, whereas effectiveness refers to its performance under ‘real-world’ conditions, and efficiency is doing things in the most economical way.

This really happened in my department! We have a mental health large dataset like 2 million responses. Some guy took around 50k responses to analyze associations between variables.They found associations with a small p-value. They interpreted the results and used it without validating with other information and did’t aware that with that large…[Read more]

I really like the discussion of common misinterpretations of power on page 345. On the point 24, “If you accept the null hypothesis because the null P value exceeds 0.05 and the power of your test is 90%, the chance you are in error (the chance that your findings a false negative) is 10%.”

This is very normal misinterpretation even I took many…[Read more]

In my opinion, relationship status is one of the potential confounders of the study result. Young adults with in relationship status are likely to have more active contact pattern. Adjusting for this variable might be appropriate to explore an association between age and contact pattern.

I have a question while doing first two assignments and reading some articles about decision tree classification.

Base on my best knowledge, if I just want to see a pattern and the association…[Read more]

I have a question about the value of between SS and total SS.
between_SS / total_SS – This can tell us how good the clustering is. We want high between_SS / total_SS percentage but do we have a criteria to tell which % is high or low?

What intervention(s) you are considering in your modelling?
I chose Ebola as my study case. I would like to study the early response or intervention for Ebola. In August 2014 the WHO published the Roadmap for response, outlining three phases of response initiatives to combat the outbreak. In October 2014, during the first phase, the UN Mission for…[Read more]
