Reinvesting in the American Workforce

July 23, 2018

Secretary of Labor

“We pledge to invest in both students and workers by providing opportunities for education and training that will help more Americans thrive in the modern workplace.”

That is a quote from the “Pledge to America’s Workers,” which is part of the White House’s new workforce initiative launched this week. President Donald Trump signed an executive order establishing the National Council for the American Worker and the American Workforce Policy Advisory Board. The council will work on a national campaign to promote investment in our nation’s workforce. The board will consist of approximately 25 leaders from the private, not-for-profit, and public sectors who will offer their expertise and advice for smart policy development.

The time to invest in the American workforce is now.

Our nation’s economy is booming. Since the president’s election, job creators have added 3.7 million new jobs. More Americans, nearly 156 million, are working than ever before. America has more open jobs than job seekers for the first time since tracking started in 2000, which is good news for Americans currently searching for jobs and those who are interested in returning to the workforce. The national unemployment rate reached an 18-year low. New record low unemployment rates were set for African-Americans, Hispanic-Americans and Asian-Americans.

As we celebrate these achievements, the next step is drilling down for more workforce development. Technology presents challenges and opportunities as we see changes to workplaces, work schedules and work arrangements. Some jobs will look different in a year. Most jobs will look very different decades from now.

We need a national commitment to embrace the rapidly, ever-changing job demands to reskill and upskill our workforce. To do that, a blend of traditional and workplace lifelong learning is required to establish a workforce that is ready for any challenge. Technology makes this easier than ever, particularly through the availability of online educational tools. Education and workforce development must work hand-in-hand to achieve the goal of family-sustaining jobs.

To that end, in May the President’s Task Force on Apprenticeship Expansion recommended ways to expand the successful “earning and learning” apprenticeship model to more industries. Expanding high-quality apprenticeships to more fields will only add to the hundreds of thousands of successful apprentices currently in the workforce through existing programs.

We must also tear down unnecessary barriers to work. Excessive licensing forces individuals, like barbers, teachers and nurses, who move from state to state, to give up their career or retake certifications and pay high fees to get back to work. The president recently signed an executive order to help alleviate the burden for military spouses as their families are reassigned from one state to another. States should also evaluate their approach to licensing — if licenses are unnecessary, eliminate them; if they are necessary for health and safety, streamline them.

President Trump is also helping to successfully transition Americans who are reentering society from prison to jobs. The Department of Labor recently released $84.4 million in grants to community groups, states and localities to advance programs that will help to reduce crime and fill open jobs.

Bureaucratic red tape can present significant barriers to work, which is why the Trump administration is restoring a commonsense approach to regulation. Workplace regulation should focus on protecting health and safety.

On Friday, I appreciated visiting Boeing in North Charleston to hear about how tax cuts, commonsense regulation and workforce investment is creating more opportunity locally. Boeing has stepped up to sign the Pledge to America’s Workers, committing to invest in South Carolina employees and those across the country. Boeing’s announcement is part of a pledge made this week at the White House by companies, trade associations and labor to provide opportunities for education and training to nearly 4 million American workers – and this number will surely grow.

Investing in the greatest workforce in the world — the American workforce — yields great returns.

Réinvestir dans la main-d'œuvre américaine

23 juillet 2018

4 minutes de lecture

Par:

R. Alexander Acosta

Secrétaire du travail
News menuAll

«Nous nous engageons à investir dans les étudiants et les travailleurs en offrant des possibilités d'éducation et de formation qui aideront plus d'américains à prospérer dans le milieu de travail moderne.»

C'est une citation de la «promesse aux travailleurs de l'Amérique», qui fait partie de l'initiative de la maison blanche nouvelle main-d'œuvre lancé cette semaine. Le président Donald Trump a signé un décret établissant le Conseil national pour le travailleur américain et le Conseil consultatif des politiques de la main-d'œuvre américaine. Le Conseil travaillera à une campagne nationale de promotion de l'investissement dans la main-d'œuvre de notre pays. Le Conseil d'administration sera composé d'environ 25 dirigeants des secteurs privé, sans but lucratif et public qui offriront leur expertise et leurs conseils pour l'élaboration de politiques judicieuses.

Le temps d'investir dans la main-d'œuvre américaine est maintenant.

L'économie de notre pays est en plein essor. Depuis l'élection présidentielle, les créateurs d'emplois ont ajouté 3,7 millions nouveaux emplois. Plus d'américains, près de 156 millions, travaillent que jamais. L'Amérique a plus d'emplois ouverts que les demandeurs d'emploi pour la première fois depuis le suivi a commencé en 2000, ce qui est une bonne nouvelle pour les américains actuellement à la recherche d'emplois et ceux qui sont intéressés à retourner à la main-d'œuvre. Le taux de chômage national a atteint un niveau de 18 ans. Un nouveau record de bas taux de chômage a été fixé pour les Afro-américains, hispano-américains et asiatiques-américains.

Au fur et à mesure que nous célébrons ces réalisations, la prochaine étape consiste à creuser pour accroître le développement de la main-d'œuvre. La technologie présente des défis et des possibilités à mesure que nous voyons des changements dans les lieux de travail, les horaires et les modalités de travail. Certains emplois auront l'air différents dans un an. La plupart des emplois auront l'air très différentes décennies à partir de maintenant.

Nous avons besoin d'un engagement national pour embrasser les demandes d'emploi rapidement et toujours changeantes de requalification et de perfectionnement de notre main-d'œuvre. Pour ce faire, il faut un mélange d'apprentissage traditionnel et de formation permanente en milieu de travail pour établir une main-d'œuvre prête à tout défi. La technologie rend cela plus facile que jamais, en particulier grâce à la disponibilité des outils éducatifs en ligne. L'éducation et le développement de la main-d'œuvre doivent travailler main dans la main pour atteindre l'objectif des emplois qui soutiennent la famille.

À cette fin, en mai, le groupe de travail du Président sur l'expansion de l'apprentissage a recommandé des moyens d'élargir le modèle d'apprentissage «gagner et apprendre» avec succès à plus d'industries. L'élargissement des apprentissages de haute qualité à un plus grand nombre de domaines ne fera qu'ajouter aux centaines de milliers d'apprentis qui réussissent actuellement dans la main-d'œuvre au moyen de programmes existants.

Nous devons aussi abattre les barrières inutiles au travail. Une licence excessive oblige les personnes, comme les barbiers, les enseignants et les infirmières, qui se déplacent d'un État à l'autre, à renoncer à leur carrière ou à reprendre des certifications et à payer des frais élevés pour se remettre au travail. Le Président a récemment signé un décret pour aider à soulager le fardeau des conjoints militaires, car leurs familles sont réaffectées d'un État à l'autre. Les États devraient également évaluer leur approche de l'octroi de licences — si les licences sont inutiles, les éliminer; Si elles sont nécessaires pour la santé et la sécurité, rationalisez-les.

Le Président Trump aide également à réussir les américains de transition qui repénètrent la société de la prison aux travaux. Le ministère du travail a récemment publié $84,4 millions en subventions aux groupes communautaires, les États et les localités à l'avance des programmes qui contribueront à réduire la criminalité et de combler les emplois vacants.

Bureaucratie bureaucratique peut présenter des obstacles importants au travail, c'est pourquoi l'administration Trump est la restauration d'une approche Commonsense de la réglementation. La réglementation en milieu de travail devrait porter sur la protection de la santé et de la sécurité.

Vendredi, j'ai apprécié visiter Boeing à North Charleston pour savoir comment les réductions d'impôt, la réglementation Commonsense et l'investissement de la main-d'œuvre est de créer plus d'opportunités localement. Boeing a intensifié pour signer le gage aux ouvriers de l'Amérique, s'engageant à investir dans les employés de la Caroline du Sud et ceux à travers le pays. L'annonce de Boeing fait partie d'une promesse faite cette semaine à la maison blanche par des entreprises, des associations professionnelles et du travail pour offrir des possibilités d'éducation et de formation à près de 4 millions travailleurs américains-et ce nombre va sûrement croître.

Investir dans la plus grande main-d'œuvre du monde — la main-d'œuvre américaine — donne de bons rendements.

NASA's Center for Near-Earth Object Studies Enters Third Decade.

On March 11, 1998, asteroid astronomers around the world received an ominous message: new observational data on the recently discovered asteroid 1997 XF11 suggested there was a chance that the half-mile-wide (nearly one kilometer) object could hit Earth in 2028.

The message came from the Minor Planet Center, in Cambridge, Massachusetts, the worldwide repository for such observations and initial determination of asteroid orbits. And although it was intended to alert only the very small astronomical community that hunts and tracks asteroids to call for more observations, the news spread quickly.

Most media outlets did not know what to make of the announcement, and mistakenly highlighted the prospect that Earth was doomed.

There are now over 18,000 known NEOs and the discovery rate averages about 40 per week. Image credit: NASA/JPL-Caltech

Fortunately, it turned out that Earth was never in danger from 1997 XF11. After performing a more thorough orbit analysis with the available asteroid observations, Don Yeomans, then the leader of the Solar System Dynamics group at NASA's Jet Propulsion Laboratory in Pasadena, California, along with his colleague Paul Chodas, concluded otherwise. "The 2028 impact was essentially impossible," said Chodas, who is now director of NASA's Center for Near-Earth Object Studies (CNEOS), located at JPL.

"To this day we still get queries on the chances of XF11 impacting in 2028," Chodas said. "There is simply no chance of XF11 impacting our planet that year, or for the next 200 years."

Chodas knows this thanks to CNEOS' precise orbit calculations using observation data submitted to the Minor Planet Center by observatories all over the world that detect and track the motion of asteroids and comets. For the past two decades, CNEOS calculations have enabled NASA to become the world leader in these efforts, keeping close watch on all nearby asteroids and comets -- especially those that can cross Earth's orbit.

"We compute high-precision orbits for all asteroids and comets and map their positions in the Solar System, both forward in time to detect potential impacts, and backward to see where they've been in the sky," Chodas said. "We provide the best map of orbits for all known small bodies in the Solar System."

Mapping the Celestial Hazard

Near-Earth Objects (NEOs) are asteroids and comets in orbits that bring them into the inner solar system, within 121 million miles (195 million kilometers) of the Sun, and also within roughly 30 million miles (50 million kilometers) of Earth's orbit around the Sun.

The media frenzy around NEO 1997 XF11 demonstrated the need for clarity and precision in communicating with the public about the close passes by Earth of these objects, as well as "the importance of peer review before public statements like these are made," Chodas said.

NASA's original intent was to fulfill a 1998 Congressional request to detect and catalogue at least 90 percent of all NEOs larger than one kilometer in size (roughly two-thirds of a mile) within 10 years. To help reach the Congressional goal, NASA Headquarters requested that JPL establish a new office to work with the data provided by the International Astronomical Union-sanctioned Minor Planet Center for submission of all observations of asteroids and comets, and to coordinate with observatories operated by academic institutions around the United States, as well as U.S. Air Force space surveillance assets.

In the summer of 1998, NASA established the Near-Earth Object Observations Program and JPL became the home for the agency's research data and analysis on NEOs, the "Near-Earth Object Program Office." (To view the announcement regarding the creation of the Near-Earth Object Program Office, see: https://www.jpl.nasa.gov/news/news.php?feature=5134)

In 2016, the office was renamed the Center for Near-Earth Object Studies (CNEOS) in conjunction with the establishment of the Planetary Defense Coordination Office (PDCO) at NASA Headquarters in Washington.

For about 20 years, CNEOS has been NASA's central hub for accurately mapping the orbits of all the known NEOs, predicting their upcoming close approaches, reliably assessing their chances of impact to our planet, and delivering that information to both astronomers worldwide and the general public.

Predicting Close Approaches and Impacts: Sentry and Scout

The first and most important step in assessing the impact risk of an asteroid or comet is to determine whether any given object's orbit will cross Earth's orbit -- and then how close it will actually get to our planet. JPL was determining high-precision orbits for a few NEOs even before NASA launched its NEO Observations Program, and has since upgraded its orbit models to provide the most accurate assessment available for asteroid positions and orbits.

Observatories around the world take digital images of the sky to detect moving points of light (the asteroid or comet) over days, weeks, months (and even decades!), and then report the positions of these moving objects relative to the static background of stars to the Minor Planet Center. See "How a Speck of Light Becomes an Asteroid".The CNEOS scientists then use all this observation data to more precisely calculate an NEO's orbit and predict its motion forward in time for many years, looking for close approaches and potential impacts to the Earth, its Moon, and other planets.

A CNEOS system called "Sentry" searches ahead for all potential future Earth impact possibilities over the next hundred years -- for every known NEO. Sentry's impact monitoring runs continually using the latest CNEOS generated orbit models, and the results are stored online.In most cases so far, the probabilities of any potential impacts are extremely small, and in other cases, the objects themselves are so small -- less than 20 meters in size, or nearly 66 feet -- that they would almost certainly disintegrate even if they did enter Earth's atmosphere.

"If Sentry finds potential impacts for an object, we add it to our online 'impact risk' table, and asteroid observers can then prioritize that object for further observation," said Steve Chesley of JPL, a member of the CNEOS team who was the main developer of the Sentry system. "The more measurementsmade of the object's position over time, the better we can predict its future path."

"In most cases, the new measurements mean the object can be removed from the risk list because the uncertainties in the orbital path are reduced and the possibility of impact is ruled out," Chesley said.

More recently, CNEOS also developed a system called Scout to provide more immediate and automatic trajectory analyses for the most recently discovered objects, even before independent observatories confirm their discovery. Operating around the clock, the Scout system not only notifies observers of the highest priority objects to observe at any given time, it also immediately alerts the Planetary Defense Coordination Office of any possible imminent impacts within the next few hours or days.A recent example is the Scout-predicted impact of the small asteroid 2018 LA over Botswana, Africa.

More Hunting to Do

With the addition of more capable NASA-funded asteroid surveys over the years, NASA's NEO Observations Program is responsible for over 90 percent of near-Earth asteroid and comet discoveries. There are now over 18,000 known NEOs and the discovery rate averages about 40 per week.

Although the original Congressional goal from 1998 has been exceeded and much progress has been made in asteroid discovery and tracking over the past two decades, the work isn't over. In 2005, Congress established a new, much more ambitious goal for the NEO Observations Program -- to discover 90 percent of the NEOs down to the much smaller size of 450 feet (140 meters), and to do so by the year 2020 (https://www.congress.gov/congressional-report/109th-congress/house-report/158/1).

These smaller asteroids may not present a threat of global catastrophe if they impact Earth, but they could still cause massive regional devastation and loss of life, especially if they occur near a metropolitan area. CNEOS continues to make improvements to its orbital analysis tools, image and graphic presentation capabilities, and updates of its websites to quickly and accurately provide the very latest information on NEOs to PDCO, the astronomical community and the public.

JPL hosts the Center for Near-Earth Object Studies for NASA's Near-Earth Object Observations Program, an element of the Planetary Defense Coordination Office within the agency's Science Mission Directorate.

L'éclipse lunaire du 27 juillet 2018 est la seconde éclipse de Lune de l'année 2018. Il s'agit d'une éclipse totale ; elle est la deuxième éclipse totale d'une série de trois, se produisant à environ 6 mois d'intervalle. C'est aussi une éclipse totale centrale, la Lune passant par le centre de l'ombre de la Terre. C'est la première éclipse lunaire centrale depuis celle du 15 juin 2011.

Puisqu'elle se produit lorsque la Lune est proche de l'apogée, cette éclipse sera aussi la plus longue éclipse lunaire totale du XXIe siècle, avec une phase de totalité de près de 103 minutes1.
Cette simulation animée montre l'apparence approximative de la Lune passant dans l'ombre de la Terre durant cette éclipse. La Lune passe par le centre de l'ombre durant cette éclipse totale centrale.

Just days after its successful installation on the International Space Station, NASA's newest Earth-observing mission, the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), has collected its first science data on Earth's surface temperature.

ECOSTRESS will measure the temperature of plants from space, enabling researchers to determine how much water plants use and to study how droughts affect plant health.

The instrument was launched June 29 from Florida's Cape Canaveral Air Force Station on a SpaceX cargo resupply mission. It rode to orbit in the "trunk" of SpaceX's Dragon spacecraft, which berthed at the station on July 2. On July 5, ground controllers at NASA's Johnson Space Center in Houston extracted ECOSTRESS from the trunk, robotically transferred it to the station's Japanese Experiment Module - Exposed Facility (JEM-EF) and installed it. After a few days of testing and start-up activities, ECOSTRESS acquired its first-light image on July 9.

"Often satellite missions require weeks or months to produce data of the quality that we are already getting from ECOSTRESS," said the mission's principal investigator, Simon Hook of NASA's Jet Propulsion Laboratory in Pasadena, California. ECOSTRESS is one of a new class of low-cost, rapid-development NASA science instruments. The ECOSTRESS instrument was launched less than four years after the project was started.

The ECOSTRESS team is now checking out the instrument and acquiring preliminary science data, a process expected to take about a month. They have completed an initial calibration of the science data and are now validating the data by comparing them with similar measurements made at ground control sites. When this process is complete, ECOSTRESS will be ready to begin its one-year science mission.

JPL built and manages the ECOSTRESS mission for NASA's Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington. ECOSTRESS is an Earth Venture Instrument mission; the program is managed by NASA's Earth System Science Pathfinder program at NASA's Langley Research Center in Hampton, Virginia.

These two images of Lake Superior and surrounding area show the first data downlinked from the CubeSat Multispectral Observation System (CUMULOS) cameras. The image on the left, taken by a short-wavelength infrared camera, captures a larger area of the lake and shows strong contrast between land and water features. The narrower field of view image on the right taken by the payload's long-wavelength infrared camera indicates a difference in water temperature between the lake's center and the water in the bays and inlets.

CUMULOS is testing the performance of commercial sensors for weather and environmental monitoring missions. The cameras are designed for point-and-stare imaging and allow nearly simultaneous coverage of Earth regions from an orbital altitude of 280 miles (452 kilometers).

CUMULOS is hosted as a demonstration of an experimental payload on NASA's Integrated Solar Array and Reflectarray Antenna (ISARA), which is managed by NASA's Jet Propulsion Laboratory in Pasadena, California, and operated by The Aerospace Corporation.
