first_imgBBC:We all experience negative emotions and find different ways to cope – maybe by exercising or by listening to music. But some people deliberately inflict pain on themselves as a way of managing how they feel. Why? Experts believe 15% of adolescents self-injure at least once, with some children as young as 9 using self-injury as a coping mechanism, albeit an unhealthy one. The behaviour can lead to feelings of guilt and distress; family and friends often don’t know how to help. Catherine Carr explores the impact self-harming has on those who do it and those close to them.She speaks to Matthew Nock, Professor of Psychology at Harvard University who explains the type of person most at risk of engaging in self-injury and the reasons why they use it to regulate their emotions.Read the whole story: BBC More of our Members in the Media >last_img read more

Study: Friend ‘sentinels’ provide early flu warning

first_imgSep 16, 2010 (CIDRAP News) – Human “sensors” who are in the hubs of friend networks can detect flu outbreaks at least 2 weeks earlier than surveillance systems that track, for example, doctors’ visits and may someday be a useful tool for identifying other diseases and behaviors, researchers reported yesterday.The novel disease detecting system depends on the “friendship paradox,” a theory that friends of given individuals are more popular than they are and are at the center of social webs, where they not only learn of gossip, trends, and ideas sooner, they may also be exposed to diseases earlier than those in more remote parts of friend networks.The researchers, Dr Nicholas Christakis, professor of medicine, medical sociology, and sociology at Harvard University and Dr James Fowler, professor of medical genetics and political science at the University of California , San Diego (UCSD), tested their friend network disease detection system at Harvard University from Sep 1 through Dec 31 during the second wave of the 2009 H1N1 pandemic. Their findings appeared yesterday in Public Library of Science (PLoS) One.They wrote that analyzing social networks and monitoring the health of central members is an ideal way to predict outbreaks, but detailed information doesn’t exist for most groups, and to produce it would be time-consuming and costly.Instead, they propose asking a random group of people to name friends, and then monitor and compare illness patterns in both groups. They emphasized that a person’s position in the friend network doesn’t indicate the actual flu transmission path, but it may serve as a proxy for an unobservable network of flu spread.Using the “friendship paradox” theory, Christakis and Fowler contacted 319 randomly selected Harvard undergraduates who named 425 friends. Many who named friends were often named by others as friends, and the same person was often nominated several times by other people. In total, the study collected information on 1,789 unique interconnected students.They monitored the two groups through self-reporting and with data from Harvard University Health Services.They found that the friends group got sick about 2 weeks before the random-student group. Using a variation of the detection method, they found, gauged by visits to the student health service, that the friends group showed flu symptoms 46 days before the epidemic peak. A figure and movie Web link that accompany the study show flu “blooming” first in the friendship network’s more central nodes.As an alternate method of identifying a high-risk group, the researchers administered a survey to measure subjects’ perceptions of their own popularity, but it did not produce an earlier flu diagnosis.Christakis said in a UCSD press release that current surveillance systems provide only a snapshot of what’s currently happening. “By simply asking members of the random group to name friends, and then tracking and comparing both groups, we can predict epidemics before they strike the population at large,” he said. “This would allow an earlier, more vigorous, and more effective response.”Fowler added that current detection methods lag the real world, or, at best, report the information in real time. “We show a way you can get ahead of an epidemic of flu, or potentially anything else that spreads in networks,” he said. The authors noted that the system could be used to identify drug-use behaviors or even the spread of new ideas and fashion fads.To put such a monitoring system into practice, the authors suggest that, for example, a university health service could gather a sample of people who are nominated as friends and who agree to be passively monitored for healthcare use, such as doctors’ visits. They said local, regional, or national health officials could pull together a random group of people, then enlist their nominated friends to report symptoms with brief, period text messages or an online survey system.”Since public health officials often monitor populations in any case, the change in practice required to monitor a sample of these more central individuals might not be too burdensome,” Christakis and Fowler wrote.They added that analysts could note when disease incidence in the friends group rose above a predetermined or background rate, or they could track both the friend and random groups and watch for when the two epidemic curves first part ways, which could be an early epidemic signal.A friend disease detection system could also be used alongside a system that tracks the online behavior in Google and other search engines to provide even better real-time information about a developing disease epidemic.Dr John Glasser, a mathematical epidemiologist at the US Centers for Disease Control and Prevention (CDC), said in the press release that the “provocative” new study will likely prompt epidemiologists and public health officials to think more about the social contexts of disease transmission.”This study may be unique in demonstrating that social position affects one’s risk of acquiring disease,” he said. “Consequently, epidemiologists and social scientists are modeling networks to evaluate novel disease surveillance and infection control strategies.”See also:Sep 15 EurekAlert press releaseSep 15 PLoS One studyFigure of flu blooming in social network hubsVideo of flu booming in social network hubslast_img read more

DNV GL Awards First AiP to Scrubber Manufacturer in China

first_imgChinese scrubber manufacturer Shanghai Bluesoul Environmental Technology has received the first Approval in Principle (AiP) by classification society DNV GL in recognition of the technical feasibility of the BlueSulf scrubber system. The AiP is said to be the first of its kind for a scrubber according to the new DNV GL rule set, and the first for a Chinese scrubber manufacturer.“We are very pleased to be the first Chinese supplier to receive this AiP and it demonstrates BlueSulf’s design in compliance with DNV GL class rules requirements, by using the sodium alkali method to clean exhaust gasses. We have signed three scrubber projects with Chinese and European owners and we are also in negotiations for several potential retrofit and new building projects,” Jacky Chow, Chief Operating Officer of Shanghai Bluesoul, said.DNV GL said it will also provide advisory services to Bluesoul, including hardware-in-the-loop testing, simulations using the DNV GL COSMOSS tool and analyses using computational fluid dynamics (CFD).BlueSulf scrubber is a hybrid system that can switch between open and closed loop mode. This type of system is said to allow greater flexibility to adjust to changes in water salinity and requirements in different ports. In some areas, the use of open loop scrubbers has been prohibited.Able to operate both on seawater and fresh water, the design reduces the sulfur content in exhaust gas to 0.1 percent or less, ensuring compliance with the requirements of the Chinese Emission Control Area (0.5 percent) that has been in force in eleven ports in China since January 1, 2017, and the upcoming global sulfur cap.last_img read more

Injuries raise doubts about Brazil’s World Cup preps

first_imgBrazil’s Neymar and teammates attend a training session in Sochi, Russia on Friday, June 29. Brazil will face Mexico on July 2 in the round of 16 for the soccer World Cup. AP SOCHI, Russia – Brazil is going out of its way to defend its World Cup preparations and show its players’ injuries can’t be blamed on excessive training.Doctors will blame a soft mattress for an injury before admitting they made mistakes getting the players ready for the tournament in Russia.Questions were raised after Renato Augusto, Danilo, Douglas Costa, and Marcelo all got hit by injuries before and during the World Cup.Augusto himself was the first to put the team’s preparations under the spotlight after he said an inflammation on his left knee was caused by the amount of training he was subjected to when he reported to the national team. The midfielder hinted he was not used to this type of training load with his team in China. And after Costa hurt a right thigh muscle in the game again Costa Rica, it was the player’s wife who raised more doubts about the team’s preparations, telling Brazilian newspaper Extra that her husband told her training with Brazil was too intense and he was used to lighter practice sessions with Italian club Juventus.After Marcelo had to be replaced only 10 minutes into the match against Serbia , doctors were immediately questioned about the team’s training load, but team doctor Rodrigo Lasmar said Marcelo’s injury might have been caused by the type of mattress he was using at the team’s hotel, not because of too much training.The team’s physical trainer, Fabio Mahseredjian, admitted the training load had to be adjusted in cases like Augusto’s, but defended the squad’s training regime during the World Cup.“Injuries will happen, it’s inevitable, and for the most varied reasons,” he said Thursday, a day after the Brazilians advanced by beating Serbia. “It’s all under control.”Although doctors said none of the injuries was serious, it wasn’t immediately clear which player would be available for Monday’s round-of-16 match against Mexico in Samara.Costa and Marcelo trained separately from their teammates Friday, while Danilo was back with rest of the squad in the practice session in Sochi. Costa exercised on the field but Marcelo did mostly rehabilitation work.The Brazilian soccer federation had said Marcelo had improved from its back problem but did not provide a timetable on his recovery.“Thank God it wasn’t anything serious,” Marcelo said on Instagram. “I’ll be back in action soon.”Costa and Danilo, who was nursing a hip injury, did not travel with the rest of the squad for the match against Serbia in Moscow. Doctors had said Costa’s problem was likely to take more time to heal.Neymar dealt with an ankle injury after the opener against Switzerland but he was back in action against Costa Rica and against Serbia.Doctors also had to take care of coach Tite, who pulled a muscle while celebrating one of the team’s goals against Costa Rica.

Ganja Legal di California, Tapi Tak Bisa Dibawa Melalui Bandara

first_imgIlustrasi ganja dengan pesawat (Boing Boing) Ketika berbicara mengenai ganja yang terpikir adalah narkoba atau obat-obatan terlarang dan melanggar hukum. Namun, apa jadinya jika beberapa negara saat ini sudah memperbolehkan membawa tanamana ganja ini dan menjadi buah tangan saat menggunakan sebuah penerbangan?Baca juga: Mau Bawa Snow Globe Selama Penerbangan? Sebaiknya Kemasi di Dalam KoperPada Januari 2018 kemarin, California terdaftar sebagai salah satu Negara Bagian di Amerika Serikat yang melegalkan adanya ganja. merangkum dari laman (7/2/2018), dikabarkan bahwa saat ini satu diantara lima orang Amerika membawa ganja dalam pot sebagai buah tangan. Tapi jika Anda masih ragu untuk mebawa ganja, baiknya hati-hati bahkan tidak perlu dibawa. Sebab ganja atau mariyuana ini masih merupakan obat ilegal dibawah undang-undang federal dan daerah pasca keamanan di bandara yang diperintah oleh badan-badan federal.Seperti di Washington, Oregon, Colorado, Alaska dan Nevada, membawa ganja dalam pot serta dibeli secara legal dan melewati pos pemeriksaan keamanan di negara bagian yang paling padat penduduknya masih dapat memicu respon penegak hukum. Transportation Security Administration (TSA) mengatakan, petugas pemeriksa tetap berfokus pada keamanan, mendeteksi senjata, bahan peledak dan ancaman lain yang bisa menganggu penerbangan dan tidak mengendus obat terlarang.Kampanye tentang ganja legalMemang mereka tidak terlalu memeriksa terkait ganja, tetapi jika petugas TSA menemukan ganja serta zat ilegal lainnya selama pemeriksaan bagasi, kebijakan akan berlaku dan akan menghubungi penegak hukum bandara setempat.“Bawaan penumpang dan tujuan penumpang tidak diperhitungkan. Respon TSA terhadap penemuan ganja sama di setiap negara bagian dan di setiap bandara, terlepas dari apakah ganja telah atau akan dilegalisir,” kata juru bicara TSA Lorie Dankers.Menurut polisi bandara Los Angeles, pihaknya yang berada di bandara Los Angeles dan Southern California lainnya, untuk penumpang yang dihentikan oleh pihak TSA dengan aduan masalah ganja, mereka tidak akan meminta apapun. Sebab membawa ganja bukanlah suatu kejahatan. Hal ini juga berlaku di bandara John Wayne di Orange County.“Jika TSA memanggil ketika menemukan ganja, kami akan naik dan memastikan jumlahnya sesuai dengan hukum. Jika begitu, kami hanya akan berdiri sementara penumpang memutuskan apa yang harus dilakukan dengan hal itu. TSA mungkin tidak menginginkannya terbang, tapi bukan berarti itu ilegal di California,” ujar Letnan Mark Gonzales, Kepala Dinas Kepolisian Bandara departemen Sheriff.Dia mengatakan, hingga saat ini, timnya belum pernah ada yang dipanggil ke pos pemeriksaan bandara oleh pihak TSA untuk menangani masalah ganja. Gonzales berujar, sepertinya penumpang tahu dan membaca peraturan, apa yang harus mereka lakukan saat melewati pos pemeriksaan.Sedangkan di bandara yang tidak melarang membawa ganja, penegak hukum setempat di panggil oleh pihak TSA untuk menjelaskan pilihan pada penumpang dan mungkin termasuk membuangnya ke tempat sampah. Tak hanya itu, penumpang juga bisa mengembalikan ke dalam mobil atau bisa dikatakan ganja tersebut tidak bisa dibawa dalam sebuah penerbangan meski legal.Bulan November 2017 lalu, Organa Brands memasang iklan mereka pada baki di pos pemeriksaan Bandara Internasional Ontario. Dengan pesan yang berbunyi “Ganja legal. Tetapi tidak bepergian dengan membawa itu. Biarkan saja di California.”Juru bicara Organa Brands, Jackson Tilley mengatakan, pihaknya yakin, jika pesan yang ada di baki tersebut adalah postif. Meskipun dia mengatakan, perusahaan tersebut tidak terlalu terkejut ketika sebulan setelah kampanye pesan-pesan tersebut dilepas.Saat ini di San Francisco, Long Beach atau bandara California lainnya sudah tidak ada lagi iklan dibaki pemeriksaan terkait ganja. Tetapi di Nevada yang mana ganja menjadi legal sejak Juli 2017 lalu memiliki cerita berbeda. Bandara Internasional Reno-Tahoe memiliki tanda di area merokok yang mengingatkan pelancong bahwa penggunaan ganja tidak diperbolehkan.“Secara umum, kami belum melihat dampak yang besar dari undang-undang baru ini di bandara. Namun, kami mengamati dengan seksama bandara lain dan bagaimana penanganannya dengan situasi unik ini,” kata juru bicara bandara Heidi Jared.Di Bandara Internasional McCarran di Las Vegas, ada larangan bandara secara resmi bagi yang memiliki ganja, dengan pemberitahuan tentang keputusan Komisi County Clark yang dimuat di situs bandara. Mulai bulan depan, tanda-tanda tentang kotak kebijakan dan amnesti untuk ganja serta produk ganja lainnya akan dipasang di lokasi-lokasi utama di McCarran, termasuk di fasilitas penyewaan mobil bandara.“Kotak pembuangan ini akan berada di luar gedung, bukan di pos pemeriksaan. Tujuannya agar produk ganja tidak diijinkan di manapun di dalam gedung, baik itu sebelum atau sesudah keamanan,” kata juru bicara McCarran Chris Jones.Baca juga: Larangan Dilonggarkan, Maskapai Cina Kini Izinkan Penumpang Aktifkan Smartphone di PesawatSementara itu, di Colorado, pada tahun 2014 adalah negara bagian pertama yang melisensikan toko untuk menjual ganja, tetapi Bandara Internasional Denver masih mempertahankan kebijakannya untuk melarang ganja di manapun pada properti bandara.“Polisi meminta penumpang yang ditemukan dengan mariyuana atau ganja untuk membuang obat tersebut. Tapi kita sudah memiliki beberapa contoh sehingga kita tidak bisa melacak kontak ini lagi,” kata juru bicara bandara Heath Montgomery.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Like this:Like Loading… RelatedDi Kanada Bawa Ganja Legal di Penerbangan Domestik18/10/2018In “Bandara”Ganja Legal, San Diego Adakan Tur Keliling Kebun31/05/2018In “Darat”Nyeleneh!

Blatter to attend FIFA appeal hearing

first_imgBy Brian HomewoodDisgraced FIFA president Sepp Blatter will return to the headquarters of football’s governing body on February 16 when his appeal against his ban from the sport will be heard, according to his advisor.Blatter, head of football’s scandal-plagued governing body since 1998, was banned in December from all football-related activity for eight years by the ethics committee of FIFA, mired in the worst graft scandal its 111-year history.“Mr Blatter will attend an appeal hearing at on February 16, at the home of FIFA, and we expect the decision as soon as possible,” his advistor Thomas Renggli told Reuters.Blatter’s case will initially be dealt with by FIFA’s own Appeal Committee. Renggli said that, if he is unsuccessful, he will go to the Court of Arbitration for Sport (CAS) in Lausanne.Blatter, 79, who has denied wrongdoing, was banned for ethics violations over a two million Swiss francs ($1.96 million) payment FIFA made to UEFA chief Michel Platini with Blatter’s approval in 2011.Platini, who had been the favourite to succeed Blatter, was also banned for eight years. The election for the new FIFA president will take place in Zurich on February 26.A total of 41 individuals and entities, including many former FIFA officials, have been charged with corruption-related offences in the United States as part of the wider scandal.The U.S. investigation is far from over and FIFA also faces a parallel Swiss investigation.last_img read more

Bahrain relaxes visas rules for business and tourism visitors

first_imgThe government of Bahrain has announced a second phase of visa updates, which will allow business visitors and tourists to spend longer periods of time in the country.In October 2014, a new visa policy was implemented, allowing nationals from over 100 countries to obtain a visa either online ahead of travel, via the Bahrain government’s e-Visa website (, or on arrival. Data from October 2014 to February 2015 show that more than 1,400 visitors from the 32 new countries eligible for visa on arrival and more than 2,300 visitors from the 36 new countries eligible for e-Visas benefited from the new policies.Under the latest developments, both business visitors and tourists will now be able to spend longer periods of time in the Gulf kingdom, as the new policy dictates that business visas will be valid for a month and are multi-entry, whilst visitor visas are valid for three months and are also multi-entry.Sheikh Ahmed bin Isa Al Khalifa, Assistant Undersecretary for the General Directorate of Nationality, Passports and Residence Affairs at Bahrain’s Ministry of Interior said, “We are pleased that the data shows that a significant number of people are already benefiting from a greater ease of access into Bahrain, supporting the business and tourism sectors in the Kingdom…The second phase of updates will lead to further benefits for visitors, with increased flexibility and expanded eligibility.”last_img read more
