25 April 2014 South Africa’s celebration of 20 years of democracy is hard earned and well deserved, Deputy President Kgalema Motlanthe said at a ceremony to mark the historic occasion at South Africa House in London on Thursday. “My gut reaction to this celebration is that we deserve it. We have earned it in many remarkable ways,” Motlanthe said. “We have earned this historic moment through the epochal struggles we launched to free the South African population from the clutches of a backward and indeed inhuman ideology.” Deputy President Motlanthe, who is on a three-day working visit to the UK, said that South Africa was a different nation to what it was two decades ago: “We are a shining example of what humanity can do to bring about a better world.”Big task The biggest task facing the country was to ensure a growing and prosperous economy to ensure a better life for all South Africans, especially those coming from a background of historic exclusion, he told the audience at South Africa House. “Without a growing economy to extricate South Africans from the abyss of poverty, unemployment and inequality, democracy holds no meaning. In fact, no democracy can survive under conditions of want, penury and social bleakness,” he said. Motlanthe said the legacy of former President Nelson Mandela, who passed away in December last year, was underscored by the preamble of the Constitution: that South Africa belongs to all who live in it, black and white. This should not be seen as a facile slogan, he said. Instead, South Africa was a microcosm of the world, where people from all corners had chosen to live. “Similarly our anti-apartheid struggle was a broad front comprising members of all sections of our society.”Support All South Africans had a good reason to celebrate the benefits attained through freedom – and so do the people of the world as a whole, he said. The celebrations, however, did not represent the end of the journey but a start to address the challenges of unemployment, poverty and inequity. Deputy President Motlanthe thanked the UK for joining in the celebrations of 20 years of freedom. He acknowledged the role played by the international community in the struggle for equality – as well as the importance of continued bilateral relations. The day 27 April 2014 will mark two decades since South Africans of all races voted in the country’s first free and fair election in 1994, ushering in a new democratic dispensation.

Baal Sabhas of government schools, which are being organised regularly at public places in the villages across Rajasthan, have turned out to be a successful experiment for raising academic standards and reducing dropout rate of students. The parents’ participation has especially made these events interactive.The latest round of Baal Sabhas was held in the State on Thursday. At the Baal Sabha in Government Higher Secondary School at Sanganer, near Jaipur, Chief Secretary D.B. Gupta said the society at large should play a meaningful role in ensuring qualitative improvement of school education.Mr. Gupta pointed out that the choice of public places for holding Baal Sabhas was aimed at bringing transparency to the drive for improving standard of education and connecting the students with extra-curricular activities. The textbooks should be used for motivating young students to explore more about their subjects, he said.While pointing out that about 86.70 lakh students were studying in 65,000 schools in the State, Mr. Gupta said the Baal Sabhas were giving them opportunities for public speaking and enhancing their confidence level. “The schools should pay attention to retention of students in addition to the increase in enrolments,” he said.Rajasthan School Education Council’s Commissioner Pradeek Kumar Borad said the Baal Sabhas had not only led to an effective participation of local communities in the management of schools, but had also helped improve creativity of students.The results of annual examinations of VI, VII, IX and XI classes were announced at the end of Baal Sabhas across the State and information about the Rajiv Gandhi career portal, launched recently, was provided on the occasion. The health check-up and immunisation camps for students were also organised at several places.
FCC This isn’t Oliver’s first time calling out the FCC. In May 2017, he aired a segment on net neutrality and asked the audience to flood the FCC with comments supporting net neutrality. Hours later, the agency’s comment system crashed. “Yes, FCC, we meet again, old friends,” said Oliver toward the end of the segment. The comedian stood on stage next to a sculpture of a giant finger about to press a huge button, saying he’d robocall the FCC commissioners every 90 minutes. “This time, unlike our past encounters, I don’t actually need to ask hordes of real people to bombard you with messages because, with the miracle of robocalling, I can now do it all by myself!”The FCC didn’t respond to a request for comment. Last Week Tonight declined to comment beyond the segment. Share your voice John Oliver joked Sunday that he’d call the FCC every 90 minutes. Screenshot by Marrian Zhou/CNET John Oliver is taking on his “old friends” at the FCC once again. On HBO’s Last Week Tonight on Sunday, the comedian zoomed in on the robocalls problem, citing research that says half of mobile phone calls in the US will soon be scam calls. The Federal Communications Commission has criticized robocalling and said it’d take action on the issue. In November, the agency said it planned to create a database that businesses can check to make sure the numbers they’ve been given permission to call haven’t been reassigned to other people. The FCC is also undertaking “light touch” regulatory actions to give wireless carriers more flexibility to block spam text messages.FCC Chairman Ajit Pai in February also called on carriers to implement robust caller ID authentication systems to combat illegal robocalls and spoofing. He said companies need to get their programs in place by the end of the year, or the FCC will consider “regulatory intervention.”However, Oliver said that’s not enough. He argued that although Pai “urged” telecom companies to implement call authentication programs, if he’d “required” them to do it, the problem might have already been fixed.

Aug 31 • iPhone 11, Apple Watch 5 and more: The final rumors J.J. Abrams (seen with musician Sara Bareilles) is reportedly producing a Stephen King-adaptation for Apple’s upcoming video streaming service. Michael Short / Getty Images Apple TV Plus is reportedly getting a third J.J. Abrams-produced show, with the latest jumping into Stephen King horror.The Cupertino, California, company ordered an eight-episode adaptation of Lisey’s Story, King’s 2006 horror-romance novel for its upcoming TV streaming service, according to The Hollywood Reporter. Apple likely paid a tidy sum for the show, since it reportedly sparked a bidding war involving several companies.Oscar winner Julianne Moore will reportedly star as Lisey Landon, who’s trying to move on two years after her novelist husband’s death. As you’d expect from horror master King, she ends up facing some dark, repressed realities about her husband and has to deal with one of his fans stalking her. 26 Photos • King will apparently write all the episodes, which are being produced by Abrams and his production company Bad Robot. It’ll be executive produced by Moore, King, Abrams and Bad Robot TV boss Ben Stephenson, Hollywood Reporter noted.Neither Apple, Abrams, Moore nor King immediately responded to requests for comment.Star Wars: Episode 9 director Abrams is already involved in two shows that’ll appear on Apple’s streaming service — the Sara Bareilles romantic comedy Little Voice and Jennifer Garner-starring drama My Glory Was I Had Such Friends.First published at 3:26 a.m. PT.Updated at 4:06 a.m. PT: Adds more details.

The content is provided for information purposes only. “There are two lines of thought when it comes to using quantum theory to describe cognitive processes,” James M. Yearsley, a researcher in the Department of Psychology at City University London, told Phys.org. “The first is that some decision-making processes appear quantum because there are physical processes in the brain (at the level of neurons, etc.) that are quantum. This is very controversial and is a position held by only a minority. The second line of thought is that basic physical processes in the brain at the level of neurons are classical, and the (apparent) non-classical features of some human decision-making arises because of the complex way in which thoughts and feelings are related to basic brain processes. This is by far the more common viewpoint, and is the one we personally subscribe to.” Memory constructionIn their study, Yearsley and Emmanuel M. Pothos, also at City University London, have proposed that quantum probability theory may be used to assign probabilities to how precisely our thoughts, decisions, feelings, memories, and other cognitive variables can be recalled and defined over time. In this view, recalling a memory at one point in time interferes with how we remember perceiving that same memory in the past or how we will perceive it in the future, much in the way a measurement may change the outcome of something being measured. This act of recall is sometimes called “constructive” because it can change (or construct) the recalled thoughts. In this view, the memory itself is essentially created by the act of remembering.As Yearsley explains, the idea that measurements might be constructive in cognition can be understood with an example of chocolate cravings.”It’s a little bit like how you can be sitting at your desk happily working away until one colleague announces that they are popping out to the shop and would you like anything, at which point you are overcome with a desire for a Twix!” he said. “That desire wasn’t there before your colleague asked, it was created by that process of measurement. In quantum approaches to cognition, cognitive variables are represented in such a way that they don’t really have values (only potentialities) until you measure them. That’s a bit like saying as it gets towards lunchtime there is an increased potentiality for you to say you’d like a Twix if someone asks you, but if you’re hard at work you might still not be thinking consciously about food. Of course, this analogy isn’t perfect.” Explore further (Phys.org) —The way that thoughts and memories arise from the physical material in our brains is one of the most complex questions in modern science. One important question in this area is how individual thoughts and memories change over time. The classical, intuitive view is that every thought, or “cognitive variable,” that we’ve ever had can be assigned a specific, well-defined value at all times of our lives. But now psychologists are challenging that view by applying quantum probability theory to how memories change over time in our brains. Citation: In quantum theory of cognition, memories are created by the act of remembering (2014, March 17) retrieved 18 August 2019 from https://phys.org/news/2014-03-quantum-theory-cognition-memories.html Quantum communication scheme provides guaranteed security without quantum memories This quantum view of memory is related to the uncertainty principle in quantum mechanics, which places fundamental limits on how much knowledge we can gain about the world. When measuring certain kinds of unknown variables in physics, such as a particle’s position and momentum, the more precisely one variable can be determined, the less precisely the other can be determined. The same is true in the proposed quantum view of cognitive processes. In this case, thoughts are linked in our cognitive system over time, in much the same way that position and momentum are linked in physics. The cognitive version can be considered as a kind of entanglement in time. As a result, perfect knowledge of a cognitive variable at one point in time requires there to be some uncertainty about it at other times. Overturning classical assumptionsThe scientists explain that this proposal can be tested by performing experiments that try to violate the so-called temporal versions of the Bell inequalities. In physics, violation of the temporal Bell inequalities signifies the failure of classical physics to describe the physical world. In cognitive science, the violations would signify the failure of classical models of cognition that make two seemingly intuitive assumptions: cognitive realism and cognitive completeness.As the scientists explain, cognitive realism is the assumption that all of the decisions a person makes can be entirely determined by processes at the neurophysiological level (although identifying all of these processes would be extremely complicated). Cognitive completeness is the assumption that the cognitive state of a person making a decision can be entirely determined by the probabilities of the outcomes of the decision. In other words, observing a person’s behavior can allow an observer to fully determine that person’s underlying cognitive state, without the need to invoke neurophysiological variables.Neither of these assumptions is controversial; in fact, both are central to many kinds of cognitive models. A quantum model, however, does not rely on these assumptions.”I think the greatest significance of this work is that it succeeds in taking the widely held belief that cognitive variables such as judgments or beliefs always have well-defined values and gives us a way to put that intuition to experimental test,” Yearsley said. “Also, assuming we do find a violation of the temporal Bell inequalities experimentally, we would be ruling out not just a single model of cognition, but actually a very large class of models, so it’s potentially a very powerful result.”Interpreting a possible violation of a temporal Bell inequality is not straightforward, since one would have to decide which of the two assumptions—realism or completeness—should be abandoned. The researchers argue that for the purposes of creating models of cognition it makes more sense to assume that cognitive realism is not valid, thus rejecting the idea that decisions can thought of as being be fully determined by underlying neurophysiological processes. A key implication would be that an individual may not have a well-defined judgment at all points in time, which may offer insight into aspects of cognition which have so far resisted formal explanation. One such example is the creation of false memories. The scientists hope that future research will help clarify the role of quantum probability in cognitive modeling, and shed light on the complicated process that make up all of our memories, thoughts, and identities.
