Senate To Debate Changes To Terrorism Prevention Act

first_img The Senate was on Friday, September 13, presented with a Bill to amend the Terrorism Prevention Act to enable Jamaica to ratify the International Convention for the Suppression of Acts of Nuclear Terrorism.The Bill also seeks to implement special recommendations made by the financial action task force in regards to money laundering and terrorism financing.The Terrorism Prevention (Amendment Act) 2013 was tabled by Minister of Foreign Affairs and Foreign Trade, Senator AJ Nicholson.Some of the provisions include expanding the definition of ‘applicable property’ to include property in the hands of the recipient of a tainted gift.According to the Act ‘applicable property’ means any property that has been used, in whole or in part to facilitate or carry out a terrorism offence; or derived, obtained or realised directly from the commission of a terrorism offence.Amendments are also being made to Section 28 of the Act to allow the Court to make an order for the monetary payment by the offender where in specified circumstances, applicable property is not susceptible to the making of a forfeiture order.Changes are also being made to provide for protection to innocent third parties in possession of applicable property.A decision has also been taken to amend the Act to enable the Financial Investigative Division to apply for monitoring orders, examination and production orders, and forfeiture orders, and restrain orders under the Act.Currently these powers only reside in the Director of Prosecutions, who will retain these powers.A decision has also been taken to amend the Act to provide for additional offences so as to enable Jamaica to ratify the International Convention for the Suppression of Acts of Nuclear Terrorism done at New York on September 14, 2005.Also the Act is being amended to accede to the 2005 amendment to the Convention on the Physical Protection of Nuclear Material; and the Protocol for the Suppression of Unlawful Acts Against the Safety of Fixed Platforms.The Bill also seeks to amend the Extradition Act and the Mutual Assistance (Criminal Matters) Act consequentially to include the above mentioned treaties falling within the provisions of those Acts. This is with a view to enabling arrangements between Jamaica and other States parties to the treaties for extradition and mutual assistance in respect of the new offences.

New insights on the nature of the star V501 Aurigae revealed

first_img More information: On the nature of the candidate T-Tauri star V501 Aurigae, arXiv:1702.04512 [astro-ph.SR] arxiv.org/abs/1702.04512AbstractWe report new multi-colour photometry and high-resolution spectroscopic observations of the long-period variable V501 Aur, previously considered to be a weak-lined T-Tauri star belonging to the Taurus-Auriga star-forming region. The spectroscopic observations reveal that V501 Aur is a single-lined spectroscopic binary system with a 68.8-day orbital period, a slightly eccentric orbit (e ~ 0.03), and a systemic velocity discrepant from the mean of Taurus-Auriga. The photometry shows quasi-periodic variations on a different, ~55-day timescale that we attribute to rotational modulation by spots. No eclipses are seen. The visible object is a rapidly rotating (vsini ~ 25 km/s) early K star, which along with the rotation period implies it must be large (R > 26.3 Rsun), as suggested also by spectroscopic estimates indicating a low surface gravity. The parallax from the Gaia mission and other independent estimates imply a distance much greater than the Taurus-Auriga region, consistent with the giant interpretation. Taken together, this evidence together with a re-evaluation of the LiI~λ6707 and Hα lines shows that V501 Aur is not a T-Tauri star, but is instead a field binary with a giant primary far behind the Taurus-Auriga star-forming region. The large mass function from the spectroscopic orbit and a comparison with stellar evolution models suggest the secondary may be an early-type main-sequence star. Water detected in the atmosphere of hot Jupiter exoplanet 51 Pegasi b V501 Aur was detected as an X-ray source in 1996 by the ROSAT space observatory. After the discovery, the source was classified as a possible new weak-lined T-Tauri star (WTTS) belonging to the Taurus-Auriga star-forming region. However, subsequent studies of this star provided evidence of its unseen stellar companion, suggesting that V501 Aur could be a single-lined spectroscopic binary.In the latest study, a team of astronomers led by Martin Vaňko of the Astronomical Institute of Slovak Academy of Sciences in Tatranská Lomnica, Slovakia, has found that V501 Aur is a single-lined spectroscopic binary star.”The spectroscopic observations reveal that V501 Aur is a single-lined spectroscopic binary system with a 68.8-day orbital period, a slightly eccentric orbit (e ∼ 0.03), and a systemic velocity discrepant from the mean of Taurus-Auriga,” the paper reads.The findings are based on a series of observational campaigns carried out between 1996 and 2016, utilizing telescopes and spectrographs worldwide. These observations allowed the team to reveal more details about the nature of this star.”Information gathered since, as well as observations reported here, paint a rather different picture of the nature of the system that we now describe,” the authors wrote.According to the paper, V501 Aur is a rapidly rotating early K star with a radius of more than 26.3 solar radii. The spectroscopic observations also indicate that V501 Aur has a fairly massive unseen companion, making it a binary star. Moreover, the new evidence shows that V501 Aur is not a T-Tauri star, but is instead a field binary far behind the Taurus-Auriga star-forming region. “The scenario that emerges for V501 Aur, aided by a comparison with stellar evolution models that succeed in matching all observational constraints, is one in which it is a background, non-eclipsing spectroscopic binary projected onto the Taurus-Auriga star-forming region, with a luminous, spotted, and fairly rapidly rotating giant star as the primary, and a likely much more rapidly rotating early-type star as the secondary,” the researchers wrote in the paper.Furthermore, the scientists estimated the mass of this binary system. Their calculations show that the primary star is about four times more massive than the sun, while its companion has a mass between 1.63 to 2.3 solar masses.The findings also indicate that the system is roughly 180 million years old and is located approximately 2,600 light years away.The team concluded that in order to uncover more details about V501 Aur, a detailed chemical analysis of this system should be performed. It could help us reveal its other parameters and improve our knowledge about its evolutionary state.

5 Ways to Control Your Email Inbox

first_img Enroll Now for Free As charges continue to swirl around hedge fund SAC Capital, Steve Cohen has put forward a novel defense: He couldn’t possibly have acted on a trading tip emailed to him because he is so swamped with emails, he ignores most of them. In fact, Cohen alleges he reads just 11 percent of the 1,000 emails he gets a day.That may help Cohen, but for other business leaders that kind of inattention could be deadly. Here’s some advice on how to get a grip before your inbox gets the best of you.Those emails sitting in your inbox — all 522 of them? Each is a decision you need to make, says Alex Moore, CEO of Baydin, a San Francisco-based email productivity software company.”The quicker you handle them, the more effective you can be,” says Moore. “Email reflects how much we have to do and an inbox with hundreds of emails is counter-productive. Too many people use their inbox as a revolving to-do list, but that’s not a good way to keep track of things. Instead, each email should be considered as a decision to be made. It should be handled, deleted or archived.”Related: 4 Easy Tools for Cleaning Up Your InboxIn January, Baydin launched ReviveYourInbox.com, a free three-week program that offers skills and methods to help tame overwhelming email inboxes. To date, about 20,000 people have gone through the program.”The people who finish often tell us it changed their life,” says Moore. He shares the first five techniques small-business owners can use to reduce the amount of email they receive and better handle the emails that matter:1. Disable notifications.The first step to taking control of your inbox is to disable the notifications that interrupt and distract your day. Checking your email might seem harmless, but Moore says a case study by Loughborough University found that it takes an average of 64 seconds to fully recover from being interrupted by an email.Unless your job demands replies within minutes, Moore says you should check your inbox two to three times a day, preferably for fixed amounts of time.2. Unsubscribe from junk emails. It may seem easy to delete junk email as it comes in, but according to Moore, deleting a newsletter every day for the next year will consume over 30 minutes. And when important emails are mixed in with unimportant ones, it’s easy to lose track of the ones that require action.3. Learn how to search email.Important message seem to hide from you when you go looking for them. Instead of using folders, Moore suggests learning about the search terms offered by many email providers. His program offers a list of basic search keywords, including “has:attachment” which will search for messages that have files attached to them; “before:” which brings up messages sent before a date; and “filename:” which will take you to emails with attachments.Related: How to Cut Your Inbox by 60 Percent4. Adopt an archive mentality.To best manage your inbox, archive messages you no longer have an immediate need for to another folder. Under this system, only two types of messages stay in your inbox: messages that you haven’t read yet and a small number of messages that need prompt attention. Everything else moves to a single archive folder. When needed, emails can be easily located using search terms.5. Clean out older messages.After you have a system in place to effectively handle new emails, it’s time to clean up the emails that were in your inbox before you started. Anything more than 30 days old can be archived without reviewing. If you discover you need it, you can search the archive folder. Handle the remaining email a little at a time over the next few days. Go through each one, and respond, archive or delete. If you have hundreds of emails, divide them into batches.”Email should be a tool that supports your business,” says Moore, “not one that detracts from it.”Related: How to Turn Your Email Into a Producivity ToolThis is an update of a piece originally published on April 3, 2013.
