control coronavirus transmission

    Since the emergence of coronavirus disease 2019 (COVID-19), unprecedented movement restrictions and social distancing measures have been implemented worldwide. The socioeconomic repercussions have fueled calls to lift these measures. In the absence of population-wide restrictions, isolation of infected individuals is key to curtailing transmission. However, the effectiveness of symptom-based isolation in preventing a resurgence depends on the extent of presymptomatic and asymptomatic transmission. We evaluate the contribution of presymptomatic and asymptomatic transmission based on recent individual-level data regarding infectiousness prior to symptom onset and the asymptomatic proportion among all infections. We found that the majority of incidences may be attributable to silent transmission from a combination of the presymptomatic stage and asymptomatic infections. Consequently, even if all symptomatic cases are isolated, a vast outbreak may nonetheless unfold. We further quantified the effect of isolating silent infections in addition to symptomatic cases, finding that over one-third of silent infections must be isolated to suppress a future outbreak below 1% of the population. Our results indicate that symptom-based isolation must be supplemented by rapid contact tracing and testing that identifies asymptomatic and presymptomatic cases, in order to safely lift current restrictions and minimize the risk of resurgence.

  • Why has business education failed business? Why has it fallen so much in love with finance and the ideas it espouses? It’s a problem with deep roots, which have been spreading for decades. It encompasses issues like the rise of neoliberal economic views as a challenge to the postwar threat of socialism. It’s about an academic inferiority complex that propelled business educators to try to emulate hard sciences like physics rather than take lessons from biology or the humanities. It dovetails with the growth of computing power that enabled complex financial modeling. The bottom line, though, is that far from empowering business, MBA education has fostered the sort of short-term, balance-sheet-oriented thinking that is threatening the economic competitiveness of the country as a whole. If you wonder why most businesses still think of shareholders as their main priority or treat skilled labor as a cost rather than an asset—or why 80 percent of CEOs surveyed in one study said they’d pass up making an investment that would fuel a decade’s worth of innovation if it meant they’d miss a quarter of earnings results— it’s because that’s exactly what they are being educated to do.

The wealth of our collective data should belong to all of us | Chris Hughes - 0 views

data mining

  • Nearly every moment of our lives, we’re producing data about ourselves that companies profit from. Our smartwatches know when we wake up, Alexa listens to our private conversations, our phones track where we go, Google knows what we email and search, Facebook knows what we share with friends, and our loyalty cards remember what we buy. We share all this data about ourselves because we like the services these companies provide, and business leaders tell us we must to make it possible for those services to be cheap or free.
  • We should not only expect that these companies better protect our data – we should also ensure that everyone creating it shares in the economic value it generates. One person’s data is worth little, but the collection of lots of people’s data is what fuels the insights that companies use to make more money or networks, like Facebook, that marketers are so attracted to. Data isn’t the “new oil”, as some have claimed: it isn’t a non-renewable natural resource that comes from a piece of earth that a lucky property owner controls. We have all pitched in to create a new commonwealth of information about ourselves that is bigger than any single participant, and we should all benefit from it.
  • The value of our data has a lot in common with the value of our labor: a single individual worker, outside of the rarest professions, can be replaced by another with similar skills. But when workers organize to withhold their labor, they have much more power to ensure employers more fairly value it. Just as one worker is an island but organized workers are a force to be reckoned with, the users of digital platforms should organize not only for better protection of our data, but for a new contract that ensures everyone shares in the historic profits we make possible.

  • A data dividend would be a powerful way to rebalance the American economy, which currently makes it possible for a very small number of people to get rich while everyone else struggles to make ends meet.
  • A data dividend on its own would not be enough to stem growing income inequality, but it would create a universal benefit that would guarantee people benefit from the collective wealth our economy is creating more than they do today. If paired with fairer wages, more progressive taxation, and stricter enforcement of monopoly and monopsony power, it could help us turn the corner and create a country where we take care of one another and ensure that everyone has basic economic security.

Tesla has installed a truly huge amount of energy storage - 0 views

  • Today, the company is announcing a new milestone: Since 2015, it has installed a worldwide total of a gigawatt-hour of energy storage–technology that is critical for using renewable energy at scale. For comparison, that’s nearly half of the entire amount of energy storage installed globally last year.
  • The cost of battery storage keeps falling; between 2010 and 2016, the price across the industry fell 73%, from $1,000 a kilowatt-hour to $273 a kilowatt-hour. By 2020, it may drop to $145 a kilowatt-hour, and by 2025, to $69.5 a kilowatt-hour.
  • The growth is only a fraction of what’s needed to transform energy. In 2015, when Elon Musk talked about the company’s new energy division, he estimated that it would take 2 billion Powerpacks to fulfill the world’s energy needs. “Even at 300%, we’ll need to grow it this way for decades, frankly, to really solve the problem,” says Straubel. “And not just us, but other companies need to get involved, too.”

climate change louisiana redeployment workforce employment

shared by Steve Bosserman on 25 May 17 - No Cached
  • According to a 2016 study by the nonprofit Greater New Orleans, this fledgling water workforce will grow by more than 20 percent over the next 10 years, creating more than 13,600 snazzy new titles like conservation technician, civil engineer and environmental scientist that pay an average of $69,277, well above the national average salary. “Louisiana is one of the first to turn the issue of climate change from an environmental one to an existential and economic one … through the cutting-edge jobs of the future,” claims Greater New Orleans’ executive vice president and chief operating officer Robin Barnes. Which is the city’s way of putting up a NOW HIRING billboard.
  • Meanwhile, troubled coastal cities around the world are taking note, says Bren Haase, head of planning for the Coastal Protection and Restoration Authority. With a playbook in place, Louisiana already boasts a 50-year, $50 billion plan to rebuild the state’s coasts, one that’s grounded in decades of data and science; it’s also being translated into several languages, including Vietnamese, Spanish and French, for other countries to reference. Flush with billions of dollars from the settlement in the catastrophic BP oil spill, the Coastal Master Plan could hold key clues for other places facing a similar fate in the future, says Haase, including flood-risk areas like New York, London, Singapore and Kiribati. Moreover, Louisiana’s coastal restoration sector is fueling high-tech projects like artificial oyster reef creation, advanced hydrologic modeling and geosynthetics, which will help shore up the state’s defenses against behemoth hurricanes and oil spills.
