The Brain as the Computer Robots Need

Posted On Dec 19 2019 by

first_imgA mind is a terrible thing to waste, especially once you realize how incredibly powerful it is.  In some ways it’s like a computer that needs maintenance; in other ways, it is too powerful to describe in machine language.  Here are a few mind matters to mind because it matters:Reboot to clear the ringing:  Many people suffer from various degrees of ringing in their ears, called tinnitus.  For the first time, there is hope for clearing this condition (which ranges from annoying to debilitating), by “rebooting” a part of the brain responsible for it.  PhysOrg reported on studies with rats that showed tinnitus could be drastically reduced or eliminated by playing certain pitches while stimulating the vagus nerve.  Instead of just masking the ringing, it actually eliminates it: “Similar to pressing a reset button in the brain, this new therapy was found to help retrain the part of the brain that interprets sound so that errant neurons reverted back to their original state and the ringing disappeared.”  New Scientist called it “brain training” that reverses ringing in ears.  Incidentally, vagus nerve stimulation (VNS) has also been effective in treating epilepsy and depression.    Another article on PhysOrg explained that tinnitus is much more than a hearing problem.  A neuroscientist said a part of the brain involved, the corticostriatal circuit, “is part of a general ‘appraisal network’ determining which sensations are important, and ultimately affecting how or whether those sensations are experienced.”  Science Daily called tinnitus “the Result of the Brain Trying, but Failing, to Repair Itself,” indicating that mechanisms are in place to keep the brain in good working order.  But when they fail, maybe a reboot is the last resort.Why music is beautiful:  When sound is organized by intelligent design in music, instead of being an accidental malfunction like tinnitus, it makes us feel wonderful and satisfied.  Why is that?  Science Daily explored why music gives us chills.  “Scientists have found that the pleasurable experience of listening to music releases dopamine, a neurotransmitter in the brain important for more tangible pleasures associated with rewards such as food, drugs and sex.”  Even the anticipation of favorite music can start the chills, the researchers at Montreal Neurological Institute and McGill University found.    According to the article, “the results suggest why music, which has no obvious survival value, is so significant across human society.”  But did it evolve?  While it may be uncontroversial that dopamine is “a neurotransmitter vital for reinforcing behavior that is necessary for survival,” suggesting that music evolved to help humans survive and pass on their genes leaves many questions hanging.  How did music get associated with dopamine release?  If it merely a physiological response of sound impinging on eardrums and nerves, why don’t all animals respond in the same way?  How do non-musical people and the deaf survive?  How can different people have different reactions to the same sounds?  Can the sensation of pleasure and chills be understood apart from a mind?Robot see, robot do:  A new “mimic-bot” was reported by New Scientist that can watch a human and learn to imitate what it sees.  “Developed by Ji-Hyeong Han and Jong-Hwan Kim at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, the system is designed to respond to the actions of the person confronting it in the same way that our own brains do,” reporter Helen Knight explained.  “The human brain contains specialised cells, called mirror neurons, that appear to fire in the same way when we watch an action being performed by others as they do when we perform the action ourselves.  It is thought that this helps us to recognise or predict their intentions.”  We can only hope these designers do better than Mickey Mouse did in “The Sorcerer’s Apprentice” in Fantasia, by ensuring the robots know the meaning of “Stop!”New Scientist intimated that robots work better by evolving.  Describing tests at the University of Vermont, where a robot learned to walk after first experimenting with crawling, reporter Paul Marks said, “Virtual robots learning to walk are steadiest on their feet when they start out with no legs and are allowed to evolve limbs over time.  As well as helping to design more stable robots, the implication is that creatures whose body plans morph as they grow may have an evolutionary advantage.”  But doesn’t that describe the stages every baby goes through? Evolution has nothing to do with these stories.  Marks made the mistake repeatedly of using evolve as an active verb or infinitive, “to evolve,” as if the robot was making a purposeful choice:Virtual robots learning to walk are steadiest on their feet when they start out with no legs and are allowed to evolve limbs over timeto seek out a virtual light source and evolve a walking gait to reach it.A third type of virtual bot had four upright legs to start with and lacked the ability to evolve its body plan.Each bot used a software routine called a genetic algorithm Movie Camera to evolve a slithering or walking gait that would best get it to the light source given its current body plan.Evolution is not an active verb.  It is the passive effect of random variations doing whatever they do, if not killing an organism.  You cannot choose to evolve any more than you can choose to grow a new sense organ by hoping that the right cosmic rays cause fortuitous mutations that produce some new sensation you cannot now fathom.  Algorithm and evolve do not belong in the same sentence, unless “evolve” is defined in the mathematical sense of “unfolding.”  Evolutionary algorithm is an oxymoron, like dishonest truth or aimless plan.    Then Marks stumbled further by confusing evolution with child development:In terms of biology, evolving behaviours like locomotion may be easier if the animal progresses through body plans that allow for gradual learning over time, says [Josh] Bongard [U of Vermont].  “This is what human infants do: they progress from crawling to walking gradually, even as the bones in the legs and feet change to accommodate the change in behaviour.”Child development is not evolution, for crying out loud.  It’s the outworking of an intelligently designed program.  This kind of equivocation over the meaning of evolution should long ago have been exploded out of the territory behind Darwinian rhetoric.  Then Marks followed that groaner with this: “The results are useful for engineers….”  Please don’t advise engineers to use evolution (in the Darwinian, biological sense) for their programs.  A mind is a terrible thing to waste.(Visited 34 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

South Africa still a net food exporter

Posted On Dec 18 2019 by

first_img3 February 2012 South Africa remains a net a food exporter, selling 30% more agricultural goods abroad than it imported in 2010, according to the latest South Africa Survey, published last month by the SA Institute of Race Relations. According to the survey by the Johannesburg-based institute, South Africa’s agricultural exports grew by 10% between 2008 and 2010, with total agricultural exports amounting to US$6.8-billion in 2010. During the same period, agricultural imports increased by just less than 1% and amounted to $5.2-billion. Agricultural exports stood at 5% of South Africa’s total exports in 2010, with agricultural imports accounting for 2% of total imports. The institute’s analysis was based on data supplied by the Foreign Agricultural Service at the United States Department of Agriculture. Netherlands SA’s biggest export destination The data revealed that the Netherlands was South Africa’s largest agricultural export destination, accounting for a little over 10% of South Africa’s total such exports in 2010, worth $700-million. Between 2008 and 2010, the demand for South African agricultural exports grew in Asia and Africa, while the proportion of such exports going to European countries declined. Argentina has remained South Africa’s largest source of agricultural imports since 2008, the survey found. However, the proportion of such imports from Argentina has fallen, from 17% in 2008 to 12% in 2010, when they were worth $628-million.Demand for SA produce ‘growing’ The ratio of South Africa’s agricultural imports to exports has increased since the mid-1960s, when the ratio of imports to exports stood at 1 to 5. In the decade between 1995 and 2005, the ratio of agricultural imports to exports stood at 2 to 3. In 2007, agricultural imports temporarily exceeded agricultural exports by a ratio of 11 to 10. “Recent data indicates that demand for South African agricultural products is not only holding steady, but is in fact growing,” Jonathan Snyman, a researcher at the institute, said in a statement. “Food security is an especially precarious state of affairs in sub-Saharan Africa, so it is a positive development that South Africa has maintained its status as a net agricultural exporter.” SAinfo reporterlast_img read more

South Africa moves to revitalise nursing

Posted On Dec 18 2019 by

first_img12 March 2013 Health Minister Aaron Motsoaledi has unveiled a national strategic plan aimed at rebuilding and revitalising the nursing profession in South Africa. The National Strategic Plan for Nurse Education, Training and Practice was developed by a task team appointed by Motsoaledi following the 2011 Nursing Summit, which identified the main challenges facing the country’s nursing profession. The plan seeks to promote high quality training along with high standards of professionalism and well-resourced practice environments for nurses and midwives. It also aims to ensure strong leadership at all levels of nursing and midwifery practice, as well as the training of the number of nurses required to deliver healthcare services in the country. Speaking at the launch of the plan in Boksburg, east of Johannesburg on Monday, Motsoaledi called on the nursing profession to come together to ensure the successful implementation of the plan. “The training of nurses is more efficient within the host environment next to the bedside in the nursing college, and from there everything else will emerge,” Motsoaledi said. He said it was crucial, as South Africa’s healthcare system was revitalised and the National Health Insurance began rolling out, that nurses were equipped to address the country’s health care needs. Motsoaledi thanked the nursing profession for the helping the country raise its life expectancy from an average 56.5 years in 2009 to 60 years in 2011. “One of the things that made us increase the life expectancy so miraculously was expanding the HIV and Aids programme, and we could not have done so without nurses.” Motsoaledi noted that in February 2010, before the government launched its voluntary HIV counselling and testing programme, there were only 250 nurses in the country that were accredited to initiate antiretroviral treatment without a doctor. Today, he said, there were over 10 000 accredited nurses. “There was no way South Africa could have achieved this with the help of doctors alone.” Source: SAnews.gov.zalast_img read more

Vermont Addresses the 20+5 Wall Problem — Sort Of

Posted On Dec 16 2019 by

first_imgThree years ago I wrote an article about a problematic recommendation in the 2012 building codes — namely, the “R-20+5” recommendation for walls in Climate Zones 6 through 8. This recommendation — actually, a prescriptive minimum R-value requirement for walls — gives code approval to walls with R-20 fiberglass batts and R-5 exterior rigid foam. (Image #2, below, shows the relevant code table.)In my article, I noted that 2×6 walls with exterior rigid foam in Zones 6 through 8 need thicker foam than the R-5 foam listed in the prescriptive table. In Zone 6, rigid foam on the exterior of 2×6 walls needs to be rated at R-11.25 or more, while in Zones 7 and 8, the foam needs to be rated at R-15 or more. (For an explanation of why thin foam can be risky, see Calculating the Minimum Thickness of Rigid Foam Sheathing.) In short, the code recommendation for R-20+5 is problematic in cold climates.When that article was being written, energy experts in Vermont were debating possible amendments to the IRC and IECC as part of the process leading up to the adoption of a 2015 residential energy code for Vermont. After my 2014 article was published, the debated amendments were finalized, and the Vermont Residential Building Energy Standards were published.Let’s look at Vermont’s solution to the R-20+5 problem. Changing the prescriptive table All of Vermont is in a single climate zone (Zone 6). So the first way that Vermont code experts amended the IRC and IECC was to remove the irrelevant climate zones from the prescriptive R-value table.While the original table in the IRC and IECC notes that walls in Zone 6 need at least “20+5 or 13+10” insulation — in other words, R-20 insulation between the studs of 2×6 walls plus R-5 of continuous insulation on the exterior of the… Sign up for a free trial and get instant access to this article as well as GBA’s complete library of premium articles and construction details.

How to Treat Other People So They Know They Matter

Posted On Dec 9 2019 by

first_imgWhen you are in a room with another person who needs your attention, do you give them your full focus? Or, does the small screen of infinite distractions make the experience less than it should be.Are you grateful for the relationships that you have and are you as gracious as you should be? My friend, Bob Burg, asked me to share this story.A few months ago, I took my son to see Alice Cooper. While I was buying those tickets, I noticed an option for a VIP experience, including a meet and greet with Alice himself. Being a fan of his music since I was 13 years old, I splurged and bought the tickets.Normally, a meet and greet means you get your picture taken, an autograph, and then you’re quickly rushed out of the room so the “star” can get on with their life. This wasn’t the case with Alice.When we showed up, we were ushered to the front of the stage to watch the band do their sound check. Then we toured the stage and got pictures with some of The Coop’s props. We were told to be at the backstage door as soon as the concert ended, and we were.Twelve of us were ushered into a room with chairs lining three of the walls, and on the fourth wall was a table and two chairs for Alice. It took a while for him to show up, because he had to take a shower and, oddly enough, eat White Castle. When he entered the room he bragged about being in the White Castle Hall of Fame; they sent him 200 hamburgers and milkshakes for his crew.And here is where the story gets interesting. The agreement says you get your picture taken with Alice and up to three items autographed. But he provided so much more than that, including a lesson in leadership and gratitude.One young woman sat next to Alice and opened a bag. In this bag she had three small ceramic dolls. They probably didn’t cost more than $10 each. The ceramic dolls were designed so that the person buying them could paint them however they wanted. She painted them to look like Alice Cooper, his wife, and his personal assistant.Alice was thrilled. He acknowledged her gift, and asked his assistants to come over and look at the wonderful artwork this young lady did. Then he made the photographer take pictures with him, her, and the small dolls. The young woman who painted the ceramic statues was beaming with joy. Clearly, it was the greatest experience of her life.Another woman asked Alice to draw a small devil on a piece of paper. He told her that he didn’t know how to draw a devil but he knew how to draw his profile. She said that would be wonderful, and he sketched out his profile with a sharpie. She then told him that she was going to have the profile and his signature tattooed on her leg. Alice, having no tattoos, asked to see all of her artwork. He took a sincere interest in each of her tattoos and asked her questions about each piece. There was no doubt in her mind that she was the most important person in the room at that moment.One man happened to catch a cane that Cooper threw into the audience at a concert many, many years ago. He brought the prop with him to ask Alice to sign it. Alice said, “I have a special gray marker just so I can sign something like this.” As he was signing the cane, the man asked him why there was black electrical tape all over the cane, suggesting it must be for the grip. Alice told him that it wasn’t for the grip, but for the balance. Then he made the gentleman stand up and he taught him to spin the cane just like he does on stage during his show. It’s impossible to describe the joy this man felt and being coached by Alice Cooper, one of his heroes.We were backstage with Mr. Cooper for 35 minutes. He was in no hurry to leave. He gave each person’s his undivided attention and focus, making them feel as if they were the most important person on earth. He was clearly grateful for their devotion, and as gracious as I’ve ever seen from any human being.It was a lesson in leadership. It was a lesson in how you treat other people, regardless of their station in life. It was a lesson in how important it is to give another human being your full attention and focus. I was impressed, and I was schooled by a master. Essential Reading!
