The study was also able to conclude that the properties of the non-root reviewers were more impactful on the cascade growth than the root reviewer, which again is very much a valid conclusion as there are much more non-root reviewers who are influenced by their personal experiences rather than other people’s reviews.
It makes sense that smaller systems have more fragile cascades since the individual reviews would be separated by large time gaps. The study was able to predict the longevity of the study much more accurately for the cities with more businesses and reviews, up to 97% for Pittsburgh. He then runs a classifying algorithm to track the features (number of reviews and friends, yelp age, gender, and average review of the user) of both the root (or cascade origin) reviewer and the non-root reviewers. To simplify the study, Khan assumes that only the friends of the person writing a review is part of his or her social group and categorizes cascades as big if their length if greater than ninety percentile of the lengths of all the cascades of that city. In this work, Khan attempts to understand and predict cascade growths using a few initial reviews and determine the features of the nodes and businesses that have high predictive power. The attached paper written by Muhammad Khan specifically looks at Yelp reviews, with each city as stand alone systems. Understanding the features behind the cascade and being able to systematically predict trends can help business owners understand the state of their own business. And similar to the situations that we have discussed in class, this might cause people to ignore their personal information on the service/business. On platforms like Facebook and Yelp, reviews could potentially have an high impact on how people new to the service/business initially perceive the that service/business. This extra knowledge can easily create biases in peoples own opinions and form information cascades. That handle’s pommel design is nice, too, even if it doesn’t provide the ergonomics and control of the Korky’s T-handle.With the information age, more people are able to see the decisions and thoughts of others on events, places, and services. Also, when the plunger is resting in the drip tray, it catches a small magnet that holds the two together, so transporting a wet plunger drip-free is as simple as clicking it into the tray and lifting the handle. But the Simplehuman’s drip tray is not just about form: In addition to hiding the plunger cup in an attractive way, it has an open back that allows for air circulation and drying, which isn’t the case with all of the drip trays we saw. With its stainless steel shaft, white accents, and stylish caddy, the Simplehuman is without question the best-looking plunger we tested. Other than the Korky, most of the tested plungers had roughly the same water-moving power, but what sets the Simplehuman apart from the rest is the overall design and the convenience of the drip tray. If the Korky is not available or if you’re willing to sacrifice plunging strength for aesthetics, we recommend the Simplehuman Toilet Plunger.
