STUDY TIP Seminal works in academic settings are the ones of central importance to a research topic. Often they report a major breakthrough, an insight or a novel thinking that stimulates later thinking. The seminal works are, in many cases, a good place to begin research, and lead to other relevant studies. The works bearing the closest relation to the present research are usually stated last before the author’s own hypothesis being proposed, functioning as the stepping stone towards this one-step-further study. As part of a course on economy and environment, you are asked to find some seminal models proposed to study how economic activities lead to environmental degradation. Where are you going to start? Weigh the following approaches and pick out the one you consider most efficient and effective.
A、Google ‘seminal models of economic activities’
B、Go to the library and look for possible books on the shelf
C、Locate seminal models from what others mentioned in relevant studies of the topic
D、Search ‘seminal economic models’ as key words from E-database of papers on economics
