The report reveals Europe now hosts the majority of child sexual abuse webpages (60%), with North America moving to second place (37%). In contrast, UK now hosts less than 0.1% of child sexual abuse imagery globally, and this is due to the zero tolerance approach the internet industry in the UK takes.Among the key findings of the report, IWF found a 258% increase in the abuse of new generic Top Level Domains (gTLDs) being used to show child sexual abuse imagery compared to 2015. Furthermore, 94% of URLs were hosted on a free-to-use service where no payment was required to create an account or upload the content.Criminals are increasingly using masking techniques to hide child sexual abuse images and videos on the internet and leaving clues to paedophiles so they can find it – hidden behind legal content. In 2016, The IWF found 1,572 websites using this method to hide child sexual abuse imagery. This is an increase of 112% on the 743 disguised websites identified in 2015.Further key findings include:92% of all child sexual abuse URLs identified globally in 2016 were hosted in five countries: Netherlands (37%), USA (22%), Canada (15%), France (11%), and Russia (7%).Social networks are among the least abused site types. Image hosting sites (72%) and cyberlockers (11%) were the most abused services.57,335 URLs contained child sexual abuse imagery and these were hosted on 2,416 domains worldwide. This is a 21% increase from 1,991 in 2015. Five top level domains (.com .net .se .io .cc) accounted for 80 per cent of all webpages identified as containing child sexual abuse images and videos.Recognising that the internet has no borders, IWF opened additional reporting portals* in 16 countries, offering more people worldwide the chance to rid the internet of this content. Susie Hargreaves OBE, IWF CEO, said: “The shift of child sexual abuse imagery hosting to Europe shows a reversal from previous years. Criminals need to use good internet hosting services which offer speed, affordability, availability and access. Services which cost nothing, and allow people to remain anonymous, are attractive.“The IWF offers a quick and effective system of self-regulation; we work with our Members to make the internet safer and we do this on the global stage.“Whilst it’s positive that the UK continues to remain hostile to child sexual abuse material, the global picture isn’t good. We’ve opened reporting portals across the globe with more planned. In other countries, internet companies are exploited and, worst of all, children who have been sexually abused are further exploited. Internet companies and large businesses who are doing nothing, or too little, to address online child sexual abuse imagery need to step up and work with us.”Mary Durham, Inspector in charge of Sexual Offences and Domestic Violence Unit in the Royal Turks and Caicos Islands Police Force said, “Since the introduction of the portal in the TCI we have not received any reports but it has shown that a number of persons have visited the site and are aware of the mechanisms that are in place for anonymous reporting of child sexual abuse images and videos. We have been educating the public about the use of the portal through presentations and via social media.“We will continue to work towards promoting the portal and the importance of it as we aim towards protecting and safeguarding our children.”Anyone can report suspected child sexual abuse images and videos anonymously at www.iwf.org.uk/tc.Press Release: RTCIPF
Manchester United manager Jose Mourinho has revealed that he was delighted with his side’s 2-1 victory over Juventus in the UEFA Champions League in Turin.The Red Devils went behind courtesy of a Cristiano Ronaldo strike, but a Juan Mata free-kick and an own goal from Alex Sandro helped secure all three points for the visitors.The former Inter Milan manager has played down cupping his ear to the Juventus supporters at the full-time whistle, saying that he “respects” the Italian giants, but the Portuguese acknowledged that he had been left “really proud” of his players.The 55-year-old told BT Sport, according to Sports Mole:Maguire says United need to build on today’s win George Patchias – September 14, 2019 Harry Maguire wants his United teammates to build on the victory over Leicester City.During the summer, Harry Maguire was referred to as the ultimate…“On a beautiful Italian day, I made a little thing. I know millions are happy with the win, but I respect Juventus and the quality they have. I am really proud of my boys because they did everything.”“We had to come and not feel inferior. We were in a situation where we thought we needed to go to the last second of the match. The boys started really well and things were under control.”“Juventus have phenomenal players. That Cristiano Ronaldo goal was beautiful and the player [Leonardo Bonucci] that made that beautiful pass, is a central defender! They are a fantastic team with an amazing record at home.”
Tiemoue Bakayoko should be an example to all AC Milan players, according to Franck Kessie.AC Milan breezed past Empoli 3-0 at the San Siro thanks to goals from Piatek, Kessie and Samu Castillejo.The win took the Rossoneri within a point of third place, awaiting Inter’s match with Fiorentina.However, the Ivorian midfielder who was on target feels Milan players should emulate the hard-work of Chelsea loanee Bakayako in their quest for a Champions League ticket.“There’s a long way to go yet. We have to keep going, pick up three points every time and continue to win,” Kessie told Football Italia.“We just have to work hard and do what the Coach asks. I have to continue like this, do better than last season and try to score more goals.”Serie A Betting: Match-day 3 Stuart Heath – September 14, 2019 Considering there is a number of perfect starts so early in the Serie A season, as well as a few surprisingly not-so perfect ones….Bakayoko was jeered during the first few months of his Milan career, on loan from Chelsea, but was given a standing ovation at San Siro tonight.Kessie goal… cheeky… #MIlan pic.twitter.com/wQNPn4PVFe— Jay 🇮🇳 (@JayGooner_) February 22, 2019“This is football, when things go badly, everyone jeers. Now Bakayoko is doing remarkable things, helps the team so much and we must remember if we all follow his example, we can win every game.”Milan are still in the hunt for the Coppa Italia and with Piatek in prolific form, it may be risky to write them off.
The announcement yesterday that longtime Hachette Filipacchi Media U.S. president and chief executive officer Jack Kliger [right] was stepping down as president and chief executive officer, to be replaced with France-based parent company Lagardère Active “directeur général délégué” Alain Lemarchand, raises several questions. Is Lemarchand’s appointment as HFMUS CEO a way for the French parent company to have more direct control over the day-to-day operations? Did Lagardère consider replacing Kliger with an internal candidate from HFMUS? Is creating a chairman position for Kliger effectively bumping him upstairs?Both Kliger and Lemarchand were unavailable for comment.A number of industry observers, though, were willing to speculate both on and off the record.One source wondered why Phillip Guelton, Hachette’s executive vice president and chief operating officer responsible for the company’s digital operations, wasn’t offered the job. “That’s the story,” the source told FOLIO:. “Why didn’t he get it? That was my first thought.” Guelton, who has been the EVP/COO at HFMUS since 2003, is well-regarded both within and outside the company, and is considered a “power player.” Guelton appears directly under Kliger on company’s masthead. Kliger served as chairman of the MPA from 2005 to 2007, a tenure marked by fire-and-brimstone speeches at industry events, during which he called on the publishers to work to improve audience metrics. ‘Easy Target’Berkery Noyes managing director Chris Shannon agreed that yesterday’s changes “were not much of a surprise,” noting how a number of large publishing companies, including Hearst, are going through executive-level changes of the guard. “[Lemarchand] is a very sharp, capable guy who has a strong global perspective,” says Shannon. “Kliger moving to chairman is good, also. They complement each other well and they will work well together.”But others weren’t so sure the move was amicable. A source said: “In this industry, when you reach a certain age and have been in the same role at a publishing company like Jack was, as an executive in this economy, you become an easy target.”Yet despite a marked downturn in consumer magazine advertising, HFMUS’ largest title, Elle, had a decent first quarter, according to Publishers Information Bureau figures, pulling in $71.8 million in ad dollars, up nearly 11 percent over the same period in 2007. Ad pages, meanwhile, were up 5 percent during the quarter. Car and Driver and Road and Track had positive performances, with revenues up 8.8 percent and 10.9 percent, respectively. HFMUS’s enthusiast division titles, though, didn’t fare as well. Cycle World saw ad dollars drop 21 percent to $7.9 million from the same period last year. Ad dollars dropped also at Boating (-19 percent) and Flying (-10.3). Ad dollars slipped slightly at its shelter titles including Elle Décor (-0.6), Home (-1.8) and Metropolitan Home (-9.3).But Kliger—who in recent years oversaw the shuttering of ElleGirl and unsuccessful import of Shock—had also made an effort to ramp up the company’s digital presence through launches and acquisitions. In 2007, for instance, Hachette acquired Jumpstart Automotive to handle online advertising sales for its auto magazine sites in a unique deal worth $110 million ($84 million in an initial cash payment, $26 million in performance bonuses). In the end, perhaps, Lagardère felt Kliger wasn’t moving fast enough.

Airbus Group SE Chief Executive Tom Enders said in statement on Wednesday that he did not see how a combination of Honeywell International Inc and United Technologies Inc (UTC) would be in his company’s interests.”I am under the impression that the leadership of UTC shares my assessment,” Enders said in the emailed statement. Airbus is one of the biggest customers of both Honeywell and UTC.UTC said on Monday that a merger with Honeywell could either be blocked outright by antitrust authorities or be conditioned on significant divestitures after a lengthy and disruptive review period that would destroy shareholder value. Honeywell countered that it did not see the regulatory process as a “material obstacle” to the deal.

(AP) — New York eliminated the religious exemption to vaccine requirements for schoolchildren, as the nation’s worst measles outbreak in decades prompts states to reconsider giving parents ways to opt out of immunization rules.The Democrat-led Senate and Assembly voted Thursday (June 13) to repeal the exemption, which allows parents to cite religious beliefs to forego getting their child the vaccines required for school enrollment.Gov. Andrew Cuomo, a Democrat, signed the measure minutes after the final vote. The law takes effect immediately but will give unvaccinated students up to 30 days after they enter a school to show they’ve had the first dose of each required immunization.With New York’s move, similar exemptions are still allowed in 45 states, though lawmakers in several of them have introduced their own legislation to eliminate the waiver.The issue is hotly contested and debate around it has often been emotional, pitting cries that religious freedom is being curtailed against warnings that public health is being endangered.After the vote in the Assembly, many of those watching from the gallery erupted in cries of “shame!” One woman yelled obscenities down to the lawmakers below.The debate has only intensified with this year’s measles outbreak , which federal officials recently said has surpassed 1,000 illnesses, the highest in 27 years.“I’m not aware of anything in the Torah, the Bible, the Koran or anything else that suggests you should not get vaccinated,” said Bronx Democrat Jeffrey Dinowitz, the bill’s Assembly sponsor.“If you choose to not vaccinate your child, therefore potentially endangering other children … then you’re the one choosing not to send your children to school.”Hundreds of parents of unvaccinated children gathered at New York’s Capitol for the vote to protest.Stan Yung, a Long Island attorney and father, said his Russian Orthodox religious views and health concerns about vaccines will prevent him from vaccinating his three young children. His family, he said, may consider leaving the state.“People came to this country to get away from exactly this kind of stuff,” Yung said ahead of Thursday’s votes.Supporters of the bill say religious beliefs about vaccines shouldn’t eclipse scientific evidence that they work, noting the U.S. Supreme Court ruled in 1905 that states have the right to enforce compulsory vaccination laws. During the Assembly’s floor debate, supporters brought up scourges of the past that were defeated in the U.S. through vaccines.“I’m old enough to have been around when polio was a real threat,” said Assemblywoman Deborah Glick, D-Manhattan. “I believe in science…. Your personal opinions, which may be based on junk science, do not trump the greater good.”Supporters also suggest some parents may be claiming the religious exemption for their children even though their opposition is actually based on scientifically discredited claims about the dangers of vaccines.The bill would not change an existing state exemption given to children who cannot have vaccines for medical reasons, such as a weakened immune system.Cuomo told reporters on Wednesday that he believes public health — and the need to protect those who cannot get vaccinated because for medical reasons — outweighs the concerns about religious freedom.“I understand freedom of religion,” he said. “I have heard the anti-vaxxers’ theory, but I believe both are overwhelmed by the public health risk.”The current measles outbreak has renewed concern about the exemptions in many states. The nation last saw as many cases in 1992, when more than 2,200 were reported.The majority of cases are from outbreaks in New York in Orthodox Jewish communities.California removed personal belief vaccine exemptions for children in both public and private schools in 2015, after a measles outbreak at Disneyland sickened 147 people and spread across the U.S. and into Canada. Maine ended its religious exemption earlier this year.Mississippi and West Virginia also do not allow religious exemptions.Once common in the U.S., measles became rare after vaccination campaigns that started in the 1960s. A decade ago, there were fewer than 100 cases a year.(David Klepper writes for The Associated Press) By: The Associated Press News Photos of the Week August 30, 2019 Facebook Twitter Pinterest LinkedIn ReddIt Email Share This!

© 2016 Phys.org Citation: Plant cellulose prevents short circuits in batteries (2016, July 22) retrieved 18 August 2019 from https://phys.org/news/2016-07-cellulose-short-circuits-batteries.html In a new study published in Nano Letters, researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea have designed a cellulose nanomat, or “c-mat,” separator membrane that contains a thin layer of nanoporous plant cellulose on top of a thick macroporous polymer layer. By finely tuning the thicknesses of the two layers, the researchers were able to design a separator membrane that delicately balances the tradeoff between preventing leakage current and supporting fast ion transport. With its tiny pores, the nanoporous cellulose layer prevents leakage current between electrodes, preventing short circuits. On the other hand, the macroporous polymer layer’s porous channels are too large to prevent leakage current between electrodes, but their large size enables them to function like “ionic highways” to rapidly transport charges.The new separator has another major advantage: At high temperatures (60 °C), batteries with the new separator membranes have an 80% capacity retention after 100 cycles, whereas batteries with typical commercial polymer separators maintain just 5% of their initial capacity after 100 cycles at the same temperature.The researchers explain that the large capacity loss in the commercial batteries at high temperature occurs due to unwanted side reactions between lithium salts and water, which produces harmful byproducts such as manganese ions. The nanoporous cellulose-based layer of the new separator membranes has a manganese-chelating ability, so that it binds to the manganese ions and prevents them from participating in the reactions that cause capacity loss. In addition, the macroporous polymer layer captures the acidic reactants that produce the manganese ions, resulting in fewer of these ions in the first place.”We demonstrate in this work that the chemically active cellulose-based c-mat separator can mitigate the manganese ion-induced adverse effects,” coauthor Sang-Young Lee, Professor at UNIST’s School of Energy and Chemical Engineering, told Phys.org. “This enables a remarkable improvement in the high-temperature cycling performance far beyond that which is attainable with conventional membrane technologies.”In the future, the researchers plan to modify the separators for potential use in next-generation rechargeable batteries such as sodium-ion, lithium-sulfur, and metal-ion batteries. “The c-mat separator is expected to be used for next-generation high-performance batteries with high temperature stability—for example, in large-sized batteries for electric vehicles and grid-scale electricity storage systems,” Lee said. In addition to its use as a battery separator membrane, the c-mat separator also has potential applications in membranes for desalination systems, as well as for ecofriendly sensors for heavy metal ions.

Credit: Kim et al. ©2016 American Chemical Society Explore further (Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery’s electrodes. There is typically a tradeoff involved, since these separators must simultaneously prevent leakage current between electrodes while allowing ions to pass through the porous channels to generate current. Conventionally, these membranes are made of synthetic materials, such as polymers.
