Trump aide cites 'massacre' that never occurred to defend immigrant ban
A Trump administration aide corrected herself on Friday after a wave of criticism for referencing a 2011 "massacre" in Kentucky that never occurred to defend President Donald Trump's temporary ban on immigrants from seven Muslim-majority countries.
During an interview with MSNBC's Chris Matthews on Thursday, White House counselor and spokeswoman Kellyanne Conway said Trump's recent executive order was justified in part because of the "Bowling Green massacre" of 2011, which never took place.
Conway corrected herself on Friday in a post on Twitter, saying: "Honest mistakes abound."
The phrase "Bowling Green massacre" was the top trending topic on Twitter on Friday morning as thousands of social media users mocked Conway's error.
On television late on Thursday, Conway spoke about two Iraqis who came to the United States and were radicalized, adding, erroneously, "and they were the masterminds behind the Bowling Green massacre."
She then said: "Most people don't know that because it didn't get covered."
In fact, in May 2011, two Iraqi men were arrested in Bowling Green, Kentucky, and charged with attempting to send weapons and money to al Qaeda in Iraq. They admitted to using improvised explosive devices against U.S. soldiers in Iraq.
Mohanad Shareef Hammadi and Waad Ramadan Alwan pleaded guilty and were sentenced to life in prison and to 40 years in prison, respectively. Neither was charged with plotting attacks within the United States, prosecutors said.
Conway said on Twitter that she meant to say "Bowling Green terrorists" on the show. She also slammed a network reporter for criticizing her.
"NBC reporter texted me at 632am re:a diff story; never asked what I meant on @Hardball b4 slamming me on @TODAYshow Not cool, not journalism," Conway (@KellyannePolls) wrote.

Like Castles In An Aquarium, Offshore Drilling Platforms Are Sprawling With Residents
Just beneath the ocean’s surface, there’s an unseen world that most people will never have the opportunity to witness firsthand. A place where nature and mankind have struck a balance – a mutual respect, a friendship of sorts.
Offshore drilling platforms have become home to vast communities of sea life. Florid carpets of coral encrust their massive pylons, along with sponge, sea urchins, crabs, and snails. Swimming in the sanctuary of their enormous risers are schools of rockfish, bright orange garibaldi and angel fish. And splashing about on the surface is the occasional sea lion.
Now scientists have confirmed what some had suspected all along. Most of the sea life was actually created at the rig rather than having come from other parts of the ocean and settled there, according to the National Academy of Sciences. And fish that would otherwise perish in vast expanses of open ocean, settle within the safety of the structures.
Like castles in an aquarium, offshore platforms are sprawling with underwater residents. Scientists say these are the richest marine ecosystems on the entire planet. They are even more productive than coral reefs and estuaries, according to marine biologists.
The first thing anyone – trained scientist or casual recreational diver – notices around a rig is the big fish -- lots of them, say marine researchers and divers, alike.
For a decade and a half, researchers used submersibles to survey fish at 16 different platforms. When the researchers tabulated the data, they were surprised to discover that, by one standard, California’s oil rigs are among the most productive marine habitats ever recorded.
At the end of their production, however, the offshore rigs must be decommissioned. Scientific insight is adding momentum to efforts to convert some of these rigs into artificial reefs […].

THE INNOVATORS OFFERING EXPATS CHEAPER SCHOOLS
A few years ago, competition for places in Dubai’s best international schools was so intense that British expat Jemma Schilbach felt she had to get her two children on the waiting lists for her preferred schools before they were even out of nappies.
Work ended up taking the family away from Dubai for a couple of years. When they returned in 2014, they were relieved to discover there were plenty more schools to choose from, but there was another issue: cost.
Both Schilbach and her husband, who’d previously worked in jobs where companies paid for children’s schooling, were now self-employed, and would need to pay for their children’s education themselves.
Schilbach, 43, who now runs expat community website BritishMums.com, enrolled both her children at Foremarke Dubai, which is affiliated with the UK independent school Repton.
She was impressed with the small class sizes and Foremarke’s reputation, but with tuition fees there starting at 65,000 AED ($18,000) a year, it meant the family had to be more careful about spending to ensure they had the money to send their children, aged five and seven, to the school.
“We economize on other costs during the year,” says Schilbach, adding that ordering some household items from the UK and closely watching what the family spends on weekends have helped to save pennies. “In our opinion, the money is better spent on educating our children to a high standard.”

Amazon rainforest’s final frontier under threat from oil and soya
Celso Carlos has made a modest living for 10 years growing manioc and coconuts and rearing poultry on a few hectares of lowland in Brazil’s northern Amazon.
But three years ago, out of the blue, Carlos was told by an Amapá state judge that he had to move because his land had been bought by a businessman living more than 1,500 miles away in São Paulo. Within months, fences had been put up, and Carlos and other assentados, or settlers, had been forced off their land.

The Operations Function
Although somewhat ‘invisible’ to the marketplace the operations function in a typical company accounts for well over half the employment and well over half the physical assets. That, in itself, makes the operations function important. In a company’s organization chart, operations often enjoys parity with the other major business functions: marketing, sales, product engineering, finance control (accounting), and human resources (personnel, labor relations). Sometimes, the operations function is organized as a single entity which stretches out across the entire company, but more often it is embedded in the district, typically product-defined divisions into which most major companies are organized.
In many service businesses, the operations function is typically more visible. Service businesses are often organized into many branches, often with geographic responsibilities – field offices, retail outlets. In such tiers of the organization, operations are paramount.
The operations function itself is, often divided
.................two major groupings .................tasks:
line management and support services. Line management generally refers.................those managers directly concerned................the manufacture of the product or the delivery of the service. They are the ones who are typically close enough to the product or service that they can ‘touch’ it. Line management supervises the hourly, blue-collar workforce. In a manufacturing company, line management frequently extends to the stockroom (where material, parts, and semi-finished products – termed ‘work-in-process inventory – are stored), materials handling, the tool room, maintenance, the warehouse (where finished goods are stored), and distribution, as well as the so-called ‘factory floor’. In a service operation, what is considered line management can broaden considerably. Often, order-taking roles, in addition to orderfilling roles, are supervised by service line managers.
Support services for line management’s operations can be numerous. Within a manufacturing environment, support services carry titles such as quality control, production planning and scheduling, purchasing, inventory control, production control (which determines the status of jobs in the factory and what to do about jobs that may have fallen behind schedule), industrial engineering (which is work methods oriented), manufacturing engineering (which is hardware-oriented), on-going product engineering, and field service. In a service environment, some of the same roles are played but sometimes under vastly different names.
Thus, the managers for whom operational issues are central can hold a variety of titles. In manufacturing, the titles can range from vice-president – manufacturing, works manager, plant manager, and similar titles at the top of the hierarchy, through such titles as manufacturing or production manager, general superintendent, department manager, materials manager, director of quality control, and down to general foreman or foreman. Within service businesses, ‘operations manager’ is sometimes used but frequently the title is more general – business manager, branch manager, retail manager, and so on.

The Pros and Cons of Nuclear Power
Since the disaster at the Fukushima nuclear power plant in Japan in 2011, a debate has been raging (1) the future of atomic energy. Consequently, the safety risks have been well publicized in the global media. But do the risks outweigh the damage that could be done to the planet because of our ongoing addiction to fossil fuels?
Even environmentalists don’t have the answer. They are split over nuclear (2) , and its pros and cons. Some say it is neither safe nor economical because it produces potentially (3) radioactive waste, and reactors are so costly to build. However, others believe nuclear energy is a necessary evil. They say we should continue using it until (4) energy sources, like wind turbines and solar panels, can meet global demand. Supporters also argue that nuclear energy helps cut down on carbon emissions from fossil fuels such as coal and natural gas, which are linked to global warming and pollute the environment. They say this is because nuclear reactors produce a tiny fraction of the carbon dioxide generated by burning coal.
But perhaps the biggest hurdle for atomic energy to overcome is its image problem. Despite industry claims of a strong safety record, critics remain unconvinced because each reactor annually produces up to 30 tons of nuclear waste, which can continue to be radioactive and hazardous for thousands of years. Furthermore, the Chernobyl disaster in 1986 left the public with vivid images of the impact of a nuclear meltdown, including deformed babies, mutated vegetables, and abandoned towns.
While nuclear reactors may continue to be installed in some countries for decades to come, after Fukushima others have decided to rethink their energy policies. For example, the German government has revealed plans for a “green” renewable energy plan, even though it has relied on nuclear power for up to 23 percent of its consumption in the past. It has been announced that all seventeen nuclear power plants would be phased out by 2022. The policy will also promote energy-saving measures encouraging people to insulate their homes, recycle, and reduce waste. Experts argue it could be a risky strategy because Germany doesn’t have natural gas or oil supplies, and coal supplies have been depleted.
Meanwhile, in Brazil, there is just one nuclear plant at Angra dos Reis. Nuclear power represents only three per cent of Brazil’s energy production. After sharp oil price rises in the 1970s, the country’s leaders anticipated future energy supply problems. So they concentrated on developing alternative energy sources including biofuel, hydroelectric schemes, and wind power.
This approach seems to be working because by May
2012 plans to build more nuclear reactors were shelved by Brazilian officials. The move was welcomed
by environmental lobby groups, which had feared a
potential ecological catastrophe in case of an accident. If a big country like Brazil, which is the tenth
largest energy consumer in the world, can survive and
improve its economy without much nuclear power,
maybe others can do so, too.
