New York, April 22, 2017: Researchers in the US have created a digital map to track the changing racial diversity of every neighbourhood in the country.

The map shows which neighbourhoods have become less homogenous over the last two decades and which have not.

Tomasz Stepinski from University of Cincinnati applied NASA mapmaking techniques to 20 years of data collected by the US Census Bureau to build one of the most detailed racial-diversity maps ever created.

The zoomable map, a paper about which was published in the journal PLOS One, shows at a glance how the racial composition of neighbourhoods changed between 1990 and 2010.

“People don’t realise that the United States is a diverse country but at the same time is still very segregated,” Stepinski, who created the map in collaboration with his postdoctoral researcher Anna Dmowska, said.

The researchers think that the map will have broad appeal to journalists, policymakers and researchers.

“The maps can tell us much more about racial composition and can be used by everyone,” Dmowska, who now works at the Institute of Geoecology and Geoinformation of Adam Mickiewicz University in Poland, said.

“They don’t require expert knowledge to understand the results, so I think maps can be used by a broader community,” Dmowska said.

Updating the maps in future census years will be relatively simple, she said.

“Our grids are ready to use for multiyear comparison,” Dmowska added.

The maps allow users to create their own smaller study area and then glean data from it.

In some cities, they tell the story of recent immigration in America. For example, the maps demonstrate the influx of Asian immigrants in San Francisco over the last 20 years.

Many of these newcomers are Southeast Asians who were drawn to the area by the Silicon Valley boom, Stepinski said.

And in Cincinnati, too, the census maps track the changing racial composition of the city.

Neighbourhoods that were predominantly White or Black in 1990 are far more diverse now.

But they also show the way that racial segregation has defined some cities.

For example, in the Detroit neighbourhoods popularised by the movie “8 Mile,” the map from 1990 clearly shows the segregation of Black and White communities on either side of 8 Mile Road. (IANS)

Facebook no longer best place to work in US, Apple gains ground.

Hit by users’ data scandals amid falling stocks this year, Facebook has lost the tag of best place to work in the US while Apple has moved up in the list of top-rated employers.

According to the leading job website Glassdoor’s annual “100 Best Places to Work in the US” list that came out on Wednesday, Boston-based management consulting firm Bain & Co. has been ranked No 1.

Facebook is now ranked No 7 — scoring 4.5 out of a perfect 5.

Apple moved up from No 84 to 71 with a score of 4.3. Microsoft moved up from No 39 to 34 as its score dropped from 4.4 to 4.3.

Microsoft-owned LinkedIn, however, is at sixth place with a score of 4.5, read the information on the Glassdoor website.

While Facebook was the best place to work in America last year, Cupertino-based tech giant Apple had tumbled to number 84 in 2017 from its 36th position in 2016.

Amazon didn’t even make it to the list, with an award score of 4.1, just outside of the top 100.

Apple, on the other hand, moved up in the ranking, from No. 84 to 71, though it maintained the same score of 4.3. Microsoft moved up in ranking from No. 39 to 34 on the list although their award score dropped from 4.4 to 4.3. Google was 8th while Salesforce came 11th.

The Top-100 list by Glassdoor is for large organisations or those with at least 1,000 employees.

The Glassdoor list came at a time when media reports said several Facebook employees are looking for better opportunities as scrutiny of the company’s conduct rises following several cases of data leak and as its stock price take a beating.

According to a CNBC report earlier this week, Facebook employees are contacting former colleagues to look for jobs outside the company.

According to a report in the Wall Street Journal last month citing an internal survey at Facebook, just over half of Facebook employees (52 per cent) said they were optimistic about the future of the social networking platform — down by 32 per cent last year.

Only 53 per cent of Facebook employees said the company was making the world better, which is 19 per cent lower than last year.

According to the report, Facebook’s “difficult year is taking a toll on employee morale, with several key measures of internal sentiment taking a sharp turn for the worse over the past year”.

Facebook investors have increased pressure on Chairman and CEO Mark Zuckerberg to step down after a New York Times investigation suggested that the social network hired a Republican-owned political consulting and PR firm that “dug up dirt on its competitors”.

Zuckerberg, however, has refused to quit. (IANS)
