While the link between fossil CO 2 emissions and atmospheric 14C has been known for many decades, the construction of a national-scale emission estimate based on atmospheric 14Crequired the simultaneous development of precise measurement techniques and an emissions estimation framework, largely spearheaded over the past 15 years by NOAA scientist John Miller and University of Colorado scientist Scott Lehman. He is now a scientist at NASA’s Goddard Space Flight Center in Maryland. “This is a new, independent, and objective method for evaluating emission inventories that is based on what we actually observe in the atmosphere,” said lead author Sourish Basu, who was a CIRES scientist working at NOAA during the study. Knowing the location, date and time when the air samples were taken, the research team used a model of atmospheric transport to disentangle the CO 2variations due to fossil fuel combustion from other natural sources and sinks, and traced the man-made variations to the fossil CO2 sources at the surface. Careful laboratory analysis can identify the degree of 14C-depletion of the CO 2 in discrete air samples, which reflects the contribution from fossil fuel combustion and cement manufacturing (which also has no 14C), otherwise known as the “fossil CO 2” contribution. The carbon in fossil fuels has been buried for millions of years and therefore is completely devoid of 14C. In a paper published in the journal the Proceedings of the National Academy of Sciences, they report the first-ever national scale estimate of fossil-fuel derived carbon dioxide (CO 2) emissions obtained by observing CO 2 and its naturally occurring radioisotope, carbon-14, from air samples collected by NOAA’s Global Greenhouse Gas Reference Network.Ĭarbon-14, or 14C, a very rare isotope of carbon created largely by cosmic rays, has a half-life of 5,700 years. Researchers from NOAA and the University of Colorado Boulder have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites. ![]()

![]() ![]() ![]() Still, the education department has a mixed track record when it comes to creating virtual options. Chalkbeat previously reported that as some districts separated virtual academies from their regular schools, there tended to be less interest in them in part because there were fewer opportunities to interact with their classmates and teachers.īefore the pandemic, New York City experimented with remote learning on a small scale, including a pilot program intended to expand access to advanced coursework for students attending 15 schools in the Bronx. Los Angeles, the nation’s second largest school district behind New York City, plans to launch new virtual schools this fall. Philadelphia and Detroit created virtual academies during the pandemic. Denver previously offered a virtual high school option but has since expanded to cover other grades. Some districts across the country, including Denver, ran virtual programs before the pandemic led to mass closures in March 2020. The city’s district schools have seen enrollment slide about 6.4% since the pandemic hit. Depending on the number of students who are allowed to enroll, the virtual schools could exacerbate enrollment problems at brick-and-mortar campuses, potentially redirecting funding from some campuses and creating more pressure to consolidate or close them. ![]() If students are allowed to enroll in separate virtual schools, that could create headaches for some schools and district leaders. Nathaniel Styer, a department spokesperson, wrote that the department “will have more to say soon.”ĭick Riley, a spokesperson for the United Federation of Teachers, wrote in an email that the union “had some initial conversations” about the virtual schools “but nothing concrete so far.” City officials did not answer emailed questions about how they will operate, such as which grades will be served, when they would start, or who would staff the program. Many details are unclear about the new virtual schools. The city’s current programming for those students typically only offers an hour a day of instruction. It may also appeal to families whose children have more significant medical issues that make them vulnerable to COVID or other illnesses. Standalone virtual schools that rely on separate teaching staff would ease that burden, though it’s not clear if that is the model officials are planning.Ī virtual model would likely appeal to parents who have lingering fears about the virus or whose children preferred remote instruction. But he indicated it was difficult to negotiate with the city’s teachers union and the option never materialized.Ĭreating separate virtual schools may help overcome one of the key problems with virtual learning during the pandemic: the task fell to individual schools to figure out how to simultaneously staff in-person and remote classrooms. And, amid the Omicron surge this winter, the schools chief said he hoped to revive virtual learning as many parents kept their children home out of fear of exposure or were stuck in quarantines. ![]() He added that students should be “exposed to the best teaching, the best experiences all over the world.”īanks has signaled since taking office in January that he’s interested in creating more permanent virtual learning options, even as the city has required all students to attend in person this school year. “I believe that virtual learning is here to stay whether or not we have a pandemic,” schools Chancellor David Banks said. About 37% of the city’s K-12 students are on track to be chronically absent, defined as missing at least 10% of the school year, substantially higher than the years before the pandemic. New York City is planning to launch two fully virtual schools, top education department officials said during a City Council hearing on Tuesday, though key details about how and when they will be created have yet to be revealed.Ĭity officials told local lawmakers that launching the “full-time” virtual schools will be part of the solution to high rates of chronic absenteeism and re-engaging students in the wake of pandemic disruption. ![]() ![]() ![]() What makes it awful and cringeworthy today is the decision not to cast a Japanese actor for the switcheroo, but to put Stockwell in embarrassing yellow face, complete with a Mickey Rooney-in- Breakfast at Tiffany’s accent.ġ52.

The Twilight Zone is known for putting toxic characters in their place through ironic cosmic justice.

It seems nothing beats a classic, so below is a ranking of every original Twilight Zone episode from worst to best to aid in your own first-time viewing or rewatch: Then came Jordan Peele, whose socially conscious horror masterwork Get Out suggested him as the perfect creative mind to carry Serling’s mantle: Fresh off the debut of his sophomore feature, Us, Peele’s 2019 spin on Serling’s series also aired one hit or miss season on CBS All Access (now Paramount+). The film’s success led to a 1985 reboot of the series, which aired for three seasons, and a 2002 version hosted by Forest Whitaker, which lasted only one. A Twilight Zone movie premiered in 1983, comprised mostly of remakes of classic episodes directed by the period’s Hollywood power players of the time. The enduring popularity of the concept has also allowed several continuations of its own. Since the original came to an end in 1964, fans have debated the best The Twilight Zone episodes (with worst Twilight Zone episodes largely ignored in syndication or TV marathons). For instance, its first copycat, The Outer Limits, was so successful its own right that it already enjoyed a seven-season reboot in the 1990s, and it would be impossible to imagine the popular Black Mirror series without The Twilight Zone’s influence. Perhaps the only detriment to being a hardcore Twilight Zone fan is the knowledge that even the most “original” high-concept movie, TV series, or novel can often be traced back to at least one episode of the series, which premiered in 1959: After all, its central themes-fear, paranoia, prejudice, greed, ego, and so on-are timeless. This made certain that “genre” fare could no longer be dismissed as mere child’s play. In the introduction to his invaluable book The Twilight Zone Companion, Marc Scott Zicree calls Rod Serling’s game-changer a “flower booming in a television desert.” It’s hard to overstate the series’ impact on our understanding of TV’s potential for telling bold, complex stories, not to mention the genres of science fiction, horror, and fantasy: In addition to defining the anthology series form, top Twilight Zone episodes embody Serling’s vision for weekly short stories with complex moral and existential quandaries. ![]() ![]() ![]() Louis on a beautiful Friday evening, and I was able to catch a glimpse of the Arch at sunset before arriving at the Missouri Athletic Club, the host site of the conference, for a pre-conference happy hour with other attendees.

With insights around probability and impact, the risk assessment work moves to determining the monetary value of risk for the entire project. Probability and Impact MatrixĪ grid for mapping the probability of occurrence of each risk and its impact on project objectives if that risk occurs. ![]() A probability and impact matrix, or as some call it, the probability and impact matrix PMP, connects the probability of a risk and the impact of that risk. Impact ValueĬost of work and resources used to address an identified risk when it occursĪ risk can impact both costs and schedule. It is always expressed as a monetary value. Impact value is the term for the cost to the project if a risk occurs. A risk assessment is incomplete without the other risk dimension: impact. The probability of showing Side 1 = (Number of favorable events) / (Total number of events).Total number of events = 2 (because the coin can either show Side A or Side B).This is that moment when a coin is tossed in the air and witnesses say quickly “Heads!” or “Tails!” reflecting their guess as to which side will land face up. The coin is tossed in the air, and the question is, what are the chances, the “probability” if you will, that it will land on Side A. The formula requires two data points: number of favorable events possible and the total number of events possible.Ī coin has two sides: one side (“heads”) is Side A, and the other (“tails”) is Side B. The probability of occurrence formula, also known to some as the “probability of occurrence formula PMP” is a tool for determining the chance that a given risk will occur. Probability matters for risk assessment and management because if there is a low probability of a risk, resources may need to be directed towards those risks with a high probability of occurrence. Project managers use tools like expert judgement or historical information from past projects to determine the probability of a particular risk occurring. Project Managers, including those working to earn a PMP® credential status, need to know the meaning of probability as part of risk assessment efforts. Probability DefinedĪ risk has the potential for a favorable outcome or a negative outcome, and in either case there is an outcome that should be considered during planning. Opportunityįrom here, the project manager needs to do a risk assessment of the probability of that each risk could happen. For risk assessment, it must have a risk-neutral assumption for proper judgment between opportunities and threats. RiskĪn uncertain event or condition that, if it occurs, has a positive or negative effect on one or more project objectives.Īssessing a risk is part of what is sometimes referred to as “probability of occurrence pmp.” One of the first steps in a risk assessment is examining each risk and determining if it is an opportunity or a threat. ![]() For risks with a potential negative impact, referred to as “threats,” the project manager should guide the work to prevent or mitigate the chances of it occurring. All risks are not bad and some lead to innovations and positive outcomes. Why would risk be managed to maximize the impact? If it is deemed a favorable risk or in other words, an “opportunity.” Perhaps the risk leads to the outcome of reduced costs or being first to market thus increasing sales. Project managers are responsible for identifying risks for projects and managing the work to maximize, prevent, and/or mitigate them. ![]() Especially since I'm the ONLY one being watched like this.

While we can’t pinpoint why the acceleration is happening, the discovery of this phenomenon gave the discovery teams a Nobel Prize in 2011.Īs the James Webb Space Telescope prepares for first light, astronomers are especially excited to use its infrared capabilities to look back at the early universe at high-redshift objects, ones that will have come from shortly after a period called the Epoch of Reionization - where the first galaxies gave the universe a transparent sheen. But we can measure the energy’s effect, as we can see the universe’s expansion is accelerating. ![]() Why the universe is accelerating as it goes is subject to debate, but the leading hypothesis is a theoretical force called “ dark energy.” Astronomers called the energy “dark” because we cannot sense it with our conventional telescopic instruments that look at waveforms of light. This led to the realization that the universe is accelerating as it expands, based on two independent studies of supernovas involving the Hubble Space Telescope and many other observatories to make sure they were seeing things correctly. Prior to this, astronomers assumed the universe was expanding at a constant rate. The surprise came in 1998, when astronomers announced supernovas were receding much faster than expected. Since we know these supernovas’ inherent brightness, we can then chart their brightness in association with distance. Astronomers have nicknamed these types of supernovas “standard candles” as they have a consistent luminosity. We know the universe is accelerating thanks to measuring the redshift of a particular type of star explosion (supernovas), called Ias. Those objects that are furthest away have the highest redshift. Astronomers still see the echoes of that Big Bang, as objects in the universe are all receding from one another, thus experiencing some degree of redshift. An event 13.8 billion years ago, dubbed the Big Bang, caused the rapid inflation and expansion of space-time. Usually, redshift is discussed when talking about the expansion of the universe. So if hydrogen observed in a star system has a lower frequency, the star system is moving away, and vice versa. When viewing objects in visible light, he added, “The universe has been kind to us.” Atoms always have characteristic frequency rates, which means we can say (for example) exactly what frequency the hydrogen in stars should be in a laboratory. The difference in motion between the observer and the source of the waves creates this effect. This is more popularly known as the Doppler effect, which is the apparent difference between the frequency of waves an observer experiences relative to the source of the waves. Sound and light have waves associated with them, so the analogy works: “Sound has a different distance to travel when the car comes towards you, instead of away from you,” Vitale tells Inverse.Īs the siren approaches, the sound increases in frequency, and as it recedes, the sound decreases in frequency. While redshift and blueshift sound esoteric, Vitale said we experience it in daily life with the sirens on ambulances and police cars. NASA Understanding blueshift and redshift This NASA visualization shows how something gradually reddens as it moves away from Earth. ![]() LIGO physicists work with astrophysicists to chart the distance to the gravitational waves they measure using redshift and blueshift - relying on multiple paths to understand the merger of some of the most potent forces in the universe. Vitale does data analysis on gravitational waves (ripples in space-time) charted by the Laser Interferometer Gravitational-Wave Observatory (LIGO) following huge events like black hole mergers. To learn more about redshift and blueshift, Inverse spoke with Salvatore Vitale, an assistant professor of physics at the Massachusetts Institute of Technology. ![]() This is important for telescopes like the James Webb Space Telescope, which its stakeholders have tasked with learning about the earliest galaxies in the infant universe. ![]() These give essential clues on things like distance - and when staring at a distant galaxy, it lets you know how close you are to staring back at the dawn of time. Blueshift is the opposite, when light is shifted to shorter wavelengths on the blue side of the spectrum as an object comes towards us. That relies on two phenomena - redshift and blueshift.Īs objects move away from us, their light gets shifted into longer wavelengths or the red end of the spectrum - that’s redshift. When astronomers stare into the deep universe or at the spectra of a distant star subtly hiding an exoplanet, they need to account for its movement. ![]() ![]() ![]() Wondershare PDFelement 2023 Key Full Torrent The app helps you to convert PDFs to office files, retaining layout formatting, and tables.
