Pavel Prikhodko, Ph.D. Machine Learning

Gun violence is one of the most widely-discussed topics in American society. Gun-related accidents and crimes take place literally every day. Shocking statistics of deaths and injuries as a result of gun violence can’t be missed. According to Gunviolencearchive.org, 51,700 incidents occurred in 2014 in the United States. More than 12,000 people were killed and 23,000 injured in accidents involving firearms. Perhaps the most terrible fact is that 628 children were killed or injured as a result of gun accidents last year.

Pavel Prikhodko, Ph.D. Machine Learning

Working from home is becoming more and more popular in the U.S. The number of people who prefer to use their own dwelling as a workplace increased slightly in the recent years. People who work 9 to 5 may start asking questions like, “who actually are home-based workers?” and “why don’t they fancy a typical job in the office?” There are main types of such workers: home workers, who work exclusively from home, home-based workers, who work from home partly or all the time, and mixed workers, who work both from home and from the office.

Fake news and stories on social media

Pavel Prikhodko, Ph.D. Machine Learning

As we saw in a previous article about digital news, there are many sources for the news today, including public social media. But are they actually true? According to a survey conducted by BuzzFeed in 2017, about 5 percent of respondents in the United States always trusted the news they saw on social media. The largest share of the respondents (31 percent) said that they trusted news on social media about half the time, while 28 percent of the respondents stated that they rarely trusted news on social media. Interestingly, 17 percent of respondents almost never trusted the news they saw on social media. Around 10 percent of people trusted news on social media most of the time.

Pavel Prikhodko, Ph.D. Machine Learning

Cement is one of the key building materials in the world, both in the residential and nonresidential sector. This material is also used for the production of concrete. Thus, more than 70 percent of cement sales in the United States went to producers of ready-mixed concrete, and about 12 percent of sales went to concrete product manufacturers. According to information published at Statista.com, around 4,100 million metric tons of cement were produced globally in 2015. The U.S. accounted for about 83.4 million metric tons of this production. The year before, 4,180 million metric tons of material were produced worldwide, and 83.2 million metric tons were produced in the U.S. In 2013, these numbers were smaller: 4,080 million metric tons globally and about 77.4 million metric tons in the U.S.

Pavel Prikhodko, Ph.D. Machine Learning

It’s no secret that the newspaper industry has hit hard times. Newspaper popularity has been declining over the last couple of years due to electronic and digital invasion. Just to compare, almost 50 percent of Americans read a newspaper on a daily basis in 2000, but by 2012 this rate had dropped to less than 30 percent. In 2012, the average American spent about $44.41 on newspapers whereas, in 2003, this number was about $53.49.

Pavel Prikhodko, Ph.D. Machine Learning

If we look at total production volume, we see that corn is the world’s most important grain. In 2014, the United States was the largest corn producer in the world with a production volume of approximately 351 million metric tons (this amounted to a third of the global corn production). According to a report by the US Department of Agriculture, the country exported over 46 million metric tons of corn in 2015. In comparison, the second-largest exporter (Brazil) produced only 22 metric tons of corn exports.
