Fake News Detection
...Computers internet Fake News Detection
Introduction
How can fake news be detected and prevented from dominating the online discourse of news events? Numerous researchers have been discussing this issue and identifying ways to detect fake news, whether on social media (Shu et al.) or by creating a benchmark dataset to facilitate the process (Wang). The topic of this study is fake news detection and what methods are available in this new field. The reason for addressing this topic is that fake news has been a hot button issue in politics ever since the election of Donald Trump. Understanding how fake new proliferates and what can be done to stop its proliferation is something that the digital community can benefit from. The inquiry question for this review is: What are some of the ways that fake news detection can be facilitated?
Body
This literature is organized according to what the researchers have found.……

...Computers internet Part 1: Concurrency Issues in the Database
1. Considering that these various transactions use some of the same tables and fields in the database, explain why it is important for the changes made by each of these transactions to be atomic. (2 pts)
Answer: The necessity of an atomic transaction, in this case, is to maintain state consistency in the database system. Since various transactions require the use of the same fields/data within the database, a sequential update to each field (prioritized based on order of transactions conducted) could lead to an imbalance in the overall system. For example: assuming a few items are sold to a customer and the sales information is updated. There is a need for an immediate update to the “QuantityOnHand” field (a reduction, since a certain unit of items have been sold), along with an update to the “total sales”, “Profit” and other relevant fields.……
