What time isit? Thatsimple question probably is asked more often today than ever. In our clock‐studded, cell‐phone society, the answer is never more than a glance away, and so we can blissfully partition our daysinto eversmaller incrementsfor ever more tightly scheduled tasks, confident that we will always know it is 7:03 P.M.

      Modern scientific revelations about time, however, make the question endlessly frustrating. If we seek a precise knowledge of the time, the elusive infinitesimal of “now” dissolves into a scattering flock of nanoseconds. Bound by the speed of light and the velocity of nerve impulses, our perceptions of the present sketch the world as it was an instant ago—for all that our consciousness pretends otherwise, we can never catch up.

      Even in principle, perfect synchronicity escapes us. Relativity dictates that, like a strange syrup, time flows slower on moving trains than in the stations and faster in the mountains than in the valleys. The time for our wristwatch or digital screen is not exactly the same as the time for our head.  

      Our intuitions are deeply paradoxical. Time heals all wounds, but it is also the great destroyer. Time is relative but also relentless. There is time for every purpose under heaven, but there is never enough.

               YOUTUBE TO BAN VIDEOS PROMOTING GUN SALES

                                                            By NIRAJ CHOKSHI    MARCH 22, 2018

      YouTube said this week that it would tighten restrictions on some firearm videos, its latest policy announcement since coming under scrutiny after last month’s mass shooting at a high school in Parkland, Fla.

      The video-streaming service, which is owned by Google, said it would ban videos that promote either the construction or sale of firearms and their accessories. The new policy, developed with expert advice over the last four months, will go into effect next month, it said.

      “While we’ve long prohibited the sale of firearms, we recently notified creators of updates we will be making around content promoting the sale or manufacture of firearms and their accessories, specifically, items like ammunition, gatling triggers, and drop-in auto sears,” YouTube said in a statement.

      YouTube, which described the move as part of “regular changes” to policy, notified users in a Monday forum post. The company had previously banned videos showing how to make firearms discharge faster, a technique used by the gunman who killed 58 people in Las Vegas last fall.

      The announcement comes days before planned student-led protests against gun violence on Saturday. It was met with frustration from gun rights advocates.

      “Much like Facebook, YouTube now acts as a virtual public square,” the National Shooting Sports Foundation, a private group representing gun makers, said in a statement. “The exercise of what amounts to censorship, then, can legitimately be viewed as the stifling of commercial free speech, which has constitutional protection. Such actions also impinge on the Second Amendment.”

      The policy shift comes as YouTube and other technology platforms face increased scrutiny after the Parkland shooting, in which 17 people were killed at Marjory Stoneman Douglas High School.

      Days after that massacre, a video promoting a baseless conspiracy about a shooting survivor became the top-trending video on YouTube, prompting a crackdown on such videos. YouTube’s chief executive also said that the platform planned to fight misinformation by working in partnership with Wikipedia, the nonprofit userrun online encyclopedia. But Wikipedia said it knew nothing about that plan.

      Other businesses have also made changes amid growing pressure following the Parkland attack.

      Dick’s Sporting Goods, Walmart and Kroger all raised the age limit for firearm purchases to 21. The retail chains REI and Mountain Equipment Co-op suspended orders of some popular products because the company that owns those brands, Vista Outdoor, also manufactures assault-style rifles.

      In 2016, Facebook announced a ban on private gun sales on its flagship website as well as on Instagram, the photo-sharing social network it owns. Anti-gun activists have complained that sellers still found ways around Facebook’s ban.

         CAN TECH DELIVER A SUSTAINABLE FUTURE FOR PLANET EARTH?

Sustainability means many things to many people, but it boils down to this: saving Planet Earth.

      Mankind1 , as a species, has been too successful for its own good – the global population is estimate to top nine billion by 2050, according to the United Nations Department of Economic and Social Affairs.

      As a result, there is already a strain2 on the planet’s essential natural resources, particularly food and water, which population growth can only aggravate.

      Meanwhile, our demand for energy has directed to the plundering3 of the earth’s hydrocarbons oil, gas and coal, producing a catastrophic climate change. In a month-long series of features on the theme of sustainability, Technology of Business will be examining the main challenges facing businesses and asking whether technology – which got us into this mess in the first place – can help get us out.

      Global megatrends are affecting the business environment

      Most companies are already being affected by climate change today, directly or indirectly, says *CDP, a global not-for-profit organization specializing in measuring business environmental impact.

       Extreme weather, drought and flooding can disrupt production capacity and affect supply chains for a whole range of businesses. For example, in a CDP survey of 70 European companies, 83% said they had operations in “water-stressed” regions, while 73% said water shortages posed risks to their own operations or those of their suppliers.

      Considering an increasingly globalised economy, few businesses can isolate themselves from the impacts of climate change, population growth and resource reduction, says Emma Price-Thomas, head of sustainability strategy at charity Business in the Community.

      “The world is changing very fast. Global megatrends are markedly affecting the business environment. If companies don’t address these and think longer-term, they may end up putting themselves out of business,” she argues.

      A lot of technology and research is being directed towards reducing water usage an industrial processes and designing products that need less water to work, she says.

      In today’s political climate, it sometimes feels like we can’t even agree on basic facts. We bombard each other with statistics and figures, hoping that more data will make a difference. A progressive person might show you the same climate change graphs over and over while a conservative person might point to the trillions of dollars of growing national debt. We’re left wondering, “Why can’t they just see? It’s so obvious!”

      Certain myths are so pervasive that no matter how many experts disprove them, they only seem to grow in popularity. There’s no shortage of serious studies showing no link between autism and vaccines, for example, but these are no match for an emotional appeal to parents worried for their young children.

      Tali Sharot, a cognitive neuroscientist at University College London, studies how our minds work and how we process new information. In her upcoming book, The Influential Mind, she explores why we ignore facts and how we can get people to actually listen to the truth. Tali shows that we’re open to new information – but only if it confirms our existing beliefs. We find ways to ignore facts that challenge our ideals. And as neuroscientist Bahador Bahrami and colleagues have found, we weigh all opinions as equally valid, regardless of expertise.

      So, having the data on your side is not always enough. For better or for worse, Sharot says, emotions may be the key to changing minds.

Opportunity Cost

This phenomenon goes by the name of ‘opportunity cost,’ since by not investing in more equipment and a more rigid production flow, the company is forgoing the opportunity to earn increased profits. These costs are every bite as real as the payment of dollars out-of-pocket.

This notion _______ opportunity cost can be reinforced _________ a famous saying ______ Benjamin Franklin, no slouch himself _________ operations management. To make the point, however, we must make a brief excursion into logic. One truth of logic is the validity of the so-called contrapositive, which says simply that if the statement “If A, then B” is true, then it is also true that “If not B, then not A.” That is, of every time A occurs B follows, then we can be sure that if B does not occur, then A did not occur as well. Enough logic then, and back to Ben Franklin.

One of his Poor Richard sayings is that “A penny saved is a penny earned.” We have all recognized the truth of that since childhood, but I assert that by this saying Ben showed us he knows everything about opportunity cost. After all, what is the contrapositive of “A penny not earned is a penny not saved (i.e., a penny sent). All we are saying by this notion of opportunity cost is that “a penny not earned (an opportunity forgone) is a penny spent.” We shall often have occasion to consider opportunity costs, in analyzing and deciding various operations issues.
