Some of the articles are well written but others are very repetitious and not rich in analysis. They are usually very short, and chould have been developed more. @More careful analysis needed. They also use a lot of "I's" in their writing. They emphasize a lot on their own experience, not what others think. Not really academically written. Some authors just repeat the same thing over and over again, which makes the whole book dull. One advantage is that it is easy to read.
