Example Input: Complexity through connections . The work of Duncan J. Watts was admittedly inspired by the work of social-psychologist at Harvard University, Stanley Milgram, in the late 1967 on experiment on the problem called "small world" problem: "anyone person in the world could be reached through a network of friends in only a few steps; in Watts language, "after the cocktail party banter in which two strangers discover that they have a mutual acquaintance and remind each other what "a small world" it is. Surprisingly, Milgram's results led to the phrase "six degrees of separation": the degree of network of friends between me and you will never be more than six! I know someone who knows someone who knows someone else who knows someone that knows someone who becomes my friend! I feel a must to urge the readers to read the book in order to understand further what science of network can give us. Among the popular books of networks, reading Watts' Six Degrees is important since the book was made seriously by the author for unlimited readers. It is a time for physics gives something valuable on constructing new scientific sociological work to day. Hokky Situngkir Bandung Fe Institut
Example Output: NEG

Example Input: Very fanciful, not data-driven . This vision of the future reminded me of common errors on physics tests where the student leaves out a variable or two and makes a wildly incorrect prediction of an object's future behavior. People have many connections to a place, which do not depend merely on their own security or on currency fluctuations. These emotional and cultural connections will keep people from being entirely atomized and "at-will" citizens for a long time to come. In reading the book, by the way, the style will annoy some rewaders in that it is not written in the modern, American style where predictions would be tied back to and grounded in data and trends. It's much more in an old fashioned English amateur gentleman scholar style where nothing is substantiated by anything and it's all sort of breezy. Some may like that.
Example Output: NEG

Example Input: Not What I Expected . I ordered this book because I really like to cook and love legumes and my pressure cooker. Perhaps I should have looked elsewhere. The recipes in here are nicely put together with the nutrition information and there is quite a bit of information on legumes. However, I found that there were too many Southwestern Chili type recipes for my taste. If you like to make chili and lots of Mexican and Southwestern inspired dishes this might be the cookbook for you. That is not to say that there aren't some Mediterranean and Caribbean inspired recipes but it just seems that the Tex-Mex and Southwestern flavors beat out the others. Also, I happen to loathe margarine and avoid it at all costs. I love to cook and would much rather use less butter or a combination of canola oil and butter or olive oil or even an olive oil spray -- anything but margarine. Not only does this cookbook call for margarine specifically, but diet margarine. In the same vein I understand that the author is an M.S., R.D. but I really don't think there is a need to use Fat-Free Dressing for everything. I also didn't like that one of the recipes called for onion soup mix. I have never purchased onion soup mix and try my best not to purchase lots of processed foods. Thus, I get very uneasy when a cookbook uses these types of ingredients. One more irksome tidbit was the fact that there weren't any recipes or mention of other beans such as the anasazi, adzuki, flageolet, cranberry to name a few. This cookbook might not be the best cookbook for someone looking for a wider repertoire of legume recipes than your Better Homes and Gardens Cookbook can offer
