STEMM

Gender gap in physics among highest in science

Physics has one of the largest gender gaps in science, technology, engineering, mathematics and medicine (STEMM) according to an analysis of more than 36 million authors of academic papers over the last two decades (PLoS Biol 16(4) e2004956). The study, carried out by researchers at the University of Melbourne in Australia, says that at current rates it will be more than two centuries until there are equal numbers of senior male and female researchers in physics.

While the proportion of women in most STEMM fields is increasing, Luke Holman and his colleagues used computational methods to estimate the speed of change. They did this by estimating the gender of 36.6 million authors on 9.7 million papers the databases PubMed and arXiv. In the latter, for example, the researchers say they were able to estimate – with 95% confidence – the gender of 1.18 million authors from 538,688 preprint published since 1991.

If we want to see 50% of physicists being women sooner we need to implement new initiatives to do this – over and above any currently-running initiatives

Of the 115 scientific disciplines examined, 87, including physics, had fewer than 45% female authors. Around 13% of last authors in physics were women – a figure that is currently increasing at a rate of just 0.1% per year. The researchers say that as last author is usually associated with seniority, based on this data, their model predicts that it will be 258 years before the gender ratio of senior physicists comes within 5% of parity. “It’s almost the most male-biased STEMM discipline that we have data for,” Holman told

The researchers also highlight computer science, maths and surgery as field with gender gaps that are likely to persist for generations. They conclude that further reforms in education, mentoring and academic publishing, beyond current initiatives, will be needed to close the STEMM gender gap. “If we want to see 50% of physicists being women sooner we need to implement new initiatives to do this – over and above any currently-running initiatives,” adds Holman.

The authors acknowledge, however, that the lack of a consistent style for authors’ names in arXiv, with many only providing initials, could have affected the quality of the analysis. Patricia Rankin, chair of the American Physical Society’s committee on the status of women in physics, also cautioned against assuming that the last author on a paper is the most senior. “The meaning of paper order can vary from field to field, in high-energy physics, for example, its often just alphabetical,” she says. “The 258 years to parity also assumes no change in the current conditions but I think we are getting much more focused on understanding why the participation of women in physics is low – and in designing evidence-based interventions.”

A Paratrooper

A paratrooper with 173rd Airborne Brigade, he led the 1990 gulf war to save the gulf oil rich nation from neighboring oil rich country's occupation. We learned a new term in military dictionary “Powell Doctrine”. A soldier’s soldier, one of the most popular in US in 1990s he and his wife Alma refused to become US President and First Lady of US. Instead In 2008, GEN Colin Powell endorsed the 44th US President Barack Obama for US#1 leadership.     




Colin Powell
UNITED STATES GENERAL AND STATESMAN
LAST UPDATED: 3-29-2018 See Article History

Alternative Title: Colin Luther Powell

Colin Powell, in full Colin Luther Powell, (born April 5, 1937, New York, New York, U.S.), U.S. general and statesman. He was chairman of the Joint Chiefs of Staff (1989–93) and secretary of state (2001–05), the first African American to hold either position.

The son of Jamaican immigrants, Powell grew up in the Harlem and South Bronx sections of New York City and attended the City College of New York (B.S., 1958), serving in the Reserve Officers’ Training Corps (ROTC). He entered the army upon graduation, served in Vietnam in 1962–63 and 1968–69, and then studied at George Washington University in Washington, D.C. In 1972 he took his first political position, as a White House fellow, and soon became an assistant to Frank Carlucci, then deputy director of the Office of Management and Budget (OMB). He held various posts over the next few years, in the Pentagon and elsewhere, and in 1983 became senior military assistant to Secretary of Defense Caspar Weinberger. In 1987 he joined the staff of the National Security Council as deputy to Carlucci, then assistant to the president for national security affairs. Late in 1987 Pres. Ronald Reagan appointed Powell to succeed Carlucci. Early in 1989 Powell took over the Army Forces Command.

In April 1989 Powell became a four-star general, and in August Pres. George Bush nominated him chairman of the Joint Chiefs of Staff. As chairman, he played a leading role in planning the invasion of Panama (1989) and the Desert Shield and Desert Storm operations of the Persian Gulf crisis and war (August 1990–March 1991; see Persian Gulf War). He retired from the military in 1993, sparking speculation that he would enter politics. Although he decided not to run for president in 1996, he joined the Republican Party and spoke out on national issues.

In 2001 he was appointed secretary of state by Pres. George W. Bush. Powell unsuccessfully sought broader international support for the Iraq War. His controversial speech before the United Nations (February 2003) was later revealed to be based on faulty intelligence. Considered a political moderate in an administration dominated by hard-liners, Powell saw his influence in the White House wane, and he announced his resignation in 2004, shortly after Bush’s reelection; he was succeeded by Condoleezza Rice in 2005. Powell’s books include the autobiography My American Journey (1995; written with Joseph E. Persico) and It Worked for Me: In Life and Leadership (2012; written with Tony Koltz).






How On Line Retail Giant Change Landscape of a City

Not very robust, but it is an interesting story

SEATTLE — Amazon.com’s extraordinary growth has turned Seattle into the biggest company town in America.

Amazon now occupies 19 percent of all prime office space in the city, the most for any employer in a major U.S. city, according to an analysis conducted for The Seattle Times.

Amazon’s presence in Seattle is more than twice as large as any other company in any other big U.S. city, and the e-commerce giant’s expansion here is just getting started.

The swarms of young workers crowding into South Lake Union every morning represent an urban campus that is unparalleled in the United States — and they have helped transform Seattle, for better or worse. Amazon’s rapid rise has fueled an economy that has driven up wages and lowered unemployment, but also produced clogged traffic on the roads and sky-high housing prices.


And while Seattle’s booming economy is often attributed to a wide variety of factors, increasingly, it’s all about one company.

Amazon now occupies more office space than the next 40 biggest employers in the city combined.

And that’s only the beginning: Amazon’s 8.1 million square feet in Seattle is expected to soar to more than 12 million square feet within five years.

Amazon’s supremacy in e-commerce and cloud computing has translated, locally, into an avalanche of glass, steel, people and money. It’s given Seattle more prominence as a magnet for talent from all over the world, and reshaped formerly forlorn parts of the city, into vibrant live-work-and-play neighborhoods.

The company’s unparalleled impact in determining Seattle’s fortunes may give some pause to those who experienced the downturn of the 1970s, when the shine of “Jet City” was tarnished as Boeing cut about two-thirds of its huge local workforce.

“Seattle’s been through this before,” said Tracey Seslen, a professor at the University of Washington’s Foster School of Business. “IfAmazon were to leave, that would create a giant hole in their wake.”

However, unlike Boeing, whose local operations focus on the single business of building airplanes, Amazon runs a vast web of mutually reinforcing but diverse businesses –– selling computing power, retailing nearly everything, publishing books and producing films, among other things.


John Schoettler, Amazon’s director of real estate, says that all he’s experienced in his nearly two decades at Amazon is “steady, continued growth,” the result of the company’s zealous focus on satisfying customers.

The legacy of what so far amounts to $4 billion spent by the company on real estate here will be long-lasting, he said: “These buildings will stand for hundreds of years.”

For this story, the real-estate data firm CoStar provided a list of all office tenants in the nation’s 20 biggest cities by population, looking at only Class A offices, the modern buildings used by the vast majority of major employers.

While other company campuses may be larger and more dominant in some suburbs — Microsoft in Redmond, Wash., or Apple, Google and Facebook in Silicon Valley — in big cities, corporate tenancy is generally fragmented.

For example, financial giant Citi has 3.7 million square feet in New York — making it the second-largest major-city office tenant in absolute terms after Amazon. But it represents less than 3 percent of Class A office space in the Big Apple.

That’s typical: In most big cities, the top employer has less than 5 percent of local office space.

Among the country’s largest 20 cities, only Columbus, Ohio — where insurer Nationwide occupies 16 percent of office space — has a situation comparable in its dominance to Amazon. But it’s still less than half of Amazon’s total square footage.

In Seattle itself, Amazon is in a league of its own. Its presence is nearly 20 times greater than that of the next-biggest employer.

Amazon got its start in a Bellevue garage in 1994, and it first grew without much of a plan — its employees were scattered in various downtown Seattle buildings and in the former Pacific Medical Center building on Beacon Hill. When Mr. Schoettler, the Amazon real-estate executive, joined the company in 2001, it had 630,000 square feet in Seattle.

In 2005, Mr. Schoettler said, he told CEO Jeff Bezos that the company needed a plan, and Mr. Bezos agreed. His only condition was that Amazon stay in downtown Seattle, Mr. Schoettler said.

That coincided with the reversal of a decades-long outflow from U.S. cities to their suburbs: By staying in the urban core, Amazon would attract members of the hip creative class.

Amazon’s expansion has led, in the short time since the end of the recession, to a “record level of private investment,” as well as significant levels of public infrastructure investment, according to John Scholes, CEO of the Downtown Seattle Association.

Over the past decade, South Lake Union has had $668 million in infrastructure improvements, including a new electrical substation under construction, the revamped Mercer Street, a new streetcar line and upgraded parks.

Amazon has become the go-to scapegoat for people complaining about Seattle’s problems associated with growth, like housing prices and clogged streets. And while it’s certainly not the only reason Seattle is bursting at the seams, Amazon makes up a disproportionate share of the city’s rapid growth.

Apartment rents this year are 63 percent higher than in 2010, as Seattle has become the fastest-growing city in the country.

Home costs are rising faster here than anywhere else in the nation, and have doubled in the past five years, pushing the middle class to surrounding, less expensive towns.

Seattle now also has the nation’s third-highest concentration of commuters who travel at least 90 minutes each way to work. Their numbers have grown 72 percent in five years.

Wages here are rising faster than anywhere else in the country, driven by Amazon’s hiring binge of employees making six figures. Unemployment is near a record low.

Amazon has begun turning around the reputation that it’s done little to alleviate the problems stemming from Seattle’s growth. The company recently said it would house a homeless shelter in one of its new offices and is offering nonprofits space for restaurants in some of its other buildings. It gave $10 million to the University of Washington last fall, created plazas for public use and has helped underwrite the South Lake Union streetcar.

Amazon’s growth has been so substantial that it can singlehandedly skew the city’s core office market, said Matthew Gardner, the chief economist of Windermere Real Estate.

In the last quarter of 2016, for example, all non-Amazon employers in Seattle’s greater downtown region shrank by a combined 150,000 square feet of office space. But Amazon gained 408,000 square feet by itself, making it a positive quarter for the market overall.

Amazon’s growing mass has also created a gravitational pull for other big tech companies on the prowl for employees. Google and Facebook have set up big offices in Seattle’s urban core, and by the end of the decade they are both poised to be among the top 10 tenants in the city.

Apple, Airbnb, Uber, the makers of Snapchat and others have also set up shop downtown after Amazon’s success in recruiting engineering talent.

That, said Ms. Seslen, the University of Washington professor, helps strengthen the local tech community.

Although Amazon, the world’s largest e-commerce company, has been long criticized for destroying Main Street retail jobs, in Seattle’s case the influx of Amazon jobs has been accompanied by a boom in local retail.

Between 2010 and 2015, retail sales in downtown Seattle have grown more than 19 percent annually — much faster than in nearby cities, according to the Downtown Seattle Association. Just in 2015, sales rose 27.5 percent, to about $1.4 billion. By comparison, Bellevue sales grew by 13.3 percent and Redmond’s by 5.7 percent that year.

Clash of Retail Giants



Clash of the Retail Giants

No feud in business was more solidified in 2018 than the one between

Amazon (Amazon is more valuable than all major brick-and-mortar retailers combined. The sum total of those investments in infrastructure and supply chain management have made Amazon by far the most valuable retailer in the United States. Amazon's $356 billion valuation is so big, it's larger than Wal-Mart, Target, Best Buy, Macy's, Kohl's, JCPenney, and Sears combined. With the recent acquisition of Whole Foods, there are no signs the retailer has any plans of slowing down)

and

Walmart (retail empire that spans 8,100 stores in 15 countries generating $401bn (£248bn) of revenue annually. With a market capitalisation of $210bn, Wal-Mart is worth more than the gross domestic product of Singapore or Malaysia or Isreal)

Walmart has quickly moved into Amazon's turf, eating away at online market share with a revamped Walmart.com. It now has an expanded online assortment and features that make shopping more convenient, like free two-day shipping with every purchase. It has seen a 60% increase in online sales this year, with no sign that it's slowing down.

Amazon's Whole Foods purchase and subsequent price cuts signaled it was moving in on Walmart's specialty of low-priced grocery. Though Whole Foods' 350-plus stores pale in comparison with Walmart's thousands of stores, the brick-and-mortar locations can serve as leverage in Amazon's quest to become a true omnichannel retailer.

It's a clash of the titans unlike anything we've seen in retail for years. Amazon's dominance online is well-documented, and Walmart's fleet of stores and hundreds of billions in sales is a matter of record. As each move in on the other's territory, we've seen some moves this year that appear to be direct responses to the other.

Walmart's partnership with Google and its voice-shopping platform is a direct response to the ubiquity of Amazon's Alexa. Amazon's lower free shipping threshold of $25 was put into place just a short while after Walmart instituted its free two-day shipping offer with every $35 purchase.

It's also gotten a little bit personal. Walmart made a point of putting the thousandth location for its click-and-pick grocery service in the new market of Seattle, squarely in Amazon territory. That also put it directly in competition with Amazon's grocery pickup service that opened this year, but only in two locations — both in Seattle.

Amazon announced a new in-home delivery service called Amazon Key. Amazon

They both also now have in-home delivery, with Walmart striking first but Amazon striking more broadly.

With these two giants duking it out, there's a already a clear winner: the consumer. There's never been a more exciting time to buy things in America. That's why we're calling Walmart vs. Amazon the biggest retail feud of 2017/2018
