Can the Sonics bounce back?

first_imgGABA/Rainforest Water/Malta Supreme…The action continues tonight in the Georgetown Amateur Basketball Association (GABA)/Rainforest Water/Malta Supreme Under-23, second-division and first-division tournament when the Pepsi Sonics clash with the in-form Plaisance Guardians.The night gets started in the second-division category at 18:30h, then the first-division players take centre stage as Sonics take on Nets at 20:30h at the Burnham Hard Court.With the Plaisance Guardians being crowned the victorious second-division champions in March 2018 at the Cliff Anderson Sports Hall, the team have always classified themselves as one of the top squads.As of recent, the Guardians have recorded a number of wins in the GABA League as they search for yet another title to add to their name. The Guardians have been in form as they demolished the Pacesetters 72-62 in their recent clash over the weekend with skipper Terrence Daniels (18), leading from the front yet again as he received valuable support from Delroy Critchlow (11) and Hillman Bovell (10).Daniels has kept his performance consistent throughout the tournament with back-to-back leading scores. Guardians have an advantage over the Sonics who seem to be having an off season.In the next match-up for the night, the Sonics will face the Nets. The Sonics have been trying to win games, but can hardly find the net as they seem to be having a dry spell.In last Saturday’s match-up, the Colts defeated the Sonics 62-51. Sonics led 20-14 after the first quarter, but the opposition’s defence got better as the game progressed which saw Sonics being outscored in the next three periods 10-15, 10-17, 11-16, respectively, to proverbially snatch defeat from the jaws of victory.In the majority of their games, the Sonics have managed to excel at the start, but somewhere along the line, they lose their flair.last_img read more

Cassini to Rewrite Textbooks on Saturn

first_imgHundreds of scientists and engineers are waiting with eager anticipation for SOI: Saturn Orbit Insertion, as the schoolbus-sized Cassini spacecraft races for its closest approach to the ringed planet tonight.  Just before closest approach, Cassini will fire its main engine for 96 minutes to slow down the spacecraft and allow Saturn to capture it in orbit (see guide to SOI and diagram on the Cassini website).    Right after the burn, for about 75 minutes, Cassini will be flying high over the rings at close range.  The instruments will gather as many measurements and pictures as it can, because it will never again be this close to the rings or to Saturn.  Scientists do not predict that the high-resolution cameras will be able to resolve individual ring particles from this range – the best resolution will be about 50 meters per pixel, and most particles are much smaller than 10 – but it may detect wakes, waves and streams that will provide clues to the dynamic evolution of ring particles over time.  There should be good sample images of all three main rings, C, B, and A, as well as the narrow F ring.  After downloading its data during the night, Cassini will point to Titan for its first of 45 encounters.    Saturn has already provided Cassini’s instruments with a puzzle: the rotation rate appears to be slowing down.  According to Cassini’s radio and plasma wave detectors, Saturn is rotating about 1% slower than when Voyager made measurements in 1981.  (This is determined by timing radio pulses in the planet’s magnetic field, which is presumed to originate from deep within the fluid planet’s interior.)  Jupiter’s rotation rate has been rock solid for 50 years of measurements, so why Saturn should show this change is without explanation at this time.  The principal investigator for the radio and plasma wave instrument suspects it has something to do with the fact that Saturn’s polar and magnetic field axes are almost perfectly aligned, to within 0.2 degree – a characteristic unique to Saturn.  All other planets with magnetic fields show an offset of 10 degrees or more.  It is that offset that generates the magnetic dynamo, according to favored models; these models, however, cannot account for a field on an axisymmetric body.  How Saturn can have a magnetic field with a negligible offset is a major puzzle Cassini scientists hope to solve.Update  Stupendous success!  The orbit insertion burn occurred flawlessly.  Cassini followed its trajectory exactly as predicted, and then turned to capture the data and images.  Relieved scientists and engineers expressed their enthusiasm at the performance of the spacecraft.  Now the four-year adventure begins.  Some of the first science results will be posted in the July issue as soon as available.We hope to be able to bring you findings and analyses that the media will miss or misinterpret.  For instance, the media will always interpret phenomena in terms of the Sacred Parameter A, the “age of the solar system” (4.5 billion years), a figure invariably assumed without question, even when apparently young phenomena are being observed.    Of special interest will be the rings, not only because of their beauty, but because of their apparent youth.  Most ring scientists believe that the rings had to form relatively recently.  Even if 100 million years were allowed, that would only be 1/50 of the Sacred Parameter.  To hold onto A, they have to invoke ad hoc theories of a comet wandering into the Roche Limit of Saturn and disrupting.  Even so, the forces of plasma drag, sputtering, micrometeorite bombardment, light pressure and collisions would dissipate the rings in short order.  Will embedded moons be found to feed new material into the rings?  Stay tuned.    Also, we will provide balance to the claims about Titan having “prebiotic chemistry” that might be like the “building blocks of life” or like the “early earth in deep freeze.”  One scientist was even heard suggesting that Titan’s atmosphere may be a natural laboratory for the Miller Experiment (see 05/02/2003 headline).  Such statements assume evolution in spite of the evidence.  Also, it will be interesting to see if long-age believers can rescue Titan’s atmosphere from the evidence it is depleting rapidly (see 10/16/2003 headline).    Cassini is poised to make major contributions to our understanding of the solar system and its age.  For now, enjoy the ride; it will be high adventure tonight at Saturn!(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Human Adaptation Can Be Rapid

first_imgHow long does it take for humans to adapt to environmental changes?  Some recent papers investigated this question.Paleface:  If it is assumed that humans started out medium or dark-skinned, how long did it take for Europeans to lose much of that original pigment?  An article in Science April 20 says maybe just 6,000 to 12,000 years.  “This contradicts a long-standing hypothesis that modern humans in Europe grew paler about 40,000 years ago, as soon as they migrated into northern latitudes,” the article states, reporting on a March meeting of the American Association of Physical Anthropologists.  Pale skin is said to have an adaptive value at high latitudes: “Under darker skies, pale skin absorbs more sunlight than dark skin, allowing ultraviolet rays to produce more vitamin D for bone growth and calcium absorption.”  The new date was based on genetic studies that suggested a “selective sweep occurred 5300 to 6000 years ago” or up to 12,000 years ago, “given the imprecision of method”.High life:  Ann Gibbons in Science reported on another discussion item from the American Association of Physical Anthropologists: how Tibetan children can tolerate the high altitude.  “Researchers seldom see Darwinian natural selection happening in living people,” she began.  “So physical anthropologist Cynthia Beall was delighted in 2004 when she discovered a trait that boosts the survival of some Tibetan children, apparently by raising the level of oxygen in their mothers’ tissues–a crucial advantage during pregnancy 4 kilometers above sea level.”  Updated research has revealed a genetic change that allows women to boost their blood volume and deliver more oxygen to the tissues.  Beall measured the selective pressure at 1:0.44, stronger than the fitness ratio measured for the sickle-cell gene.  They said, “the adaptation represents some of the strongest natural selection yet measured in humans.”    Surprisingly, this appears to be a different adaptation mechanism than that found in populations living in the Andes.  There, mothers are able to boost the amount of hemoglobin.  These correlations are uncertain, however; “it’s quite possible that the Tibetans have evolved more than one way to boost blood oxygen,” Beall cautioned.  Mark Gladwin threw in a Darwinian proverb: “Study the pregnant women, because that’s where you’ll see evolution in action.”Got milk?  Another strong selection effect in humans is for lactose tolerance.  Current Biology (April 17) had an article on this phenomenon, which “might have meant the difference between life and death” to early dairy farmers, Greg Gibson (North Carolina State U) said.  The admittedly imperfect ability to tolerate lactose represents another selective sweep some 5,000 to 10,000 years ago, about the time humans began to domesticate cattle.  He remarked, “It is hard to refute that this is a lovely example of the coevolution of genes and culture.”    Nevertheless, Gibson spent most of the article debunking the “thrifty genes” hypothesis of evolutionary selection.  This is a 45-year-old idea that the “high incidence of diabetes in modern humans is a result of positive selection for alleles that confer the ability to rapidly sequester rare caches of carbohydrates as fat that would tide us over during famine.”  This adaptation now works against us in our urbanized society, it is claimed: it tends us toward obesity.  So why does Gibson think this is a poor hypothesis?  “Unfortunately, these three preconditions for natural selection are all too often mistaken by adaptationists as both necessary and sufficient for evolution to occur,” he cautioned.  But we need to be more quantitative if sufficiency is to be proven.”  At the end, he was even more emphatic: “Those inclined toward Darwinian medicine like to explain disease as the price we pay for the beneficial effects of alleles that have accompanied human adaptation.  These cases of not-so-thrifty genes suggest though that we should not be so quick to jump on the bandwagon: the coevolution of genes and culture is tremendously more complex.”Funny he should mention Darwinian medicine.  A paper on that very subject appeared in Public Library of Science: Biology this month.  Catriona J. MacCallum tried again to make the case that medical doctors need to study evolution to understand disease (cf. 01/13/2003.  Distressed that medical schools are not considering evolution essential to the curriculum (see 06/25/2003), MacCallum wrote,It is curious that Charles Darwin, perhaps medicine’s most famous dropout, provided the impetus for a subject that figures so rarely in medical education.  Indeed, even the iconic textbook example of evolution—antibiotic resistance—is rarely described as “evolution” in relevant papers published in medical journals.  Despite potentially valid reasons for this oversight (e.g., that authors of papers in medical journals would regard the term as too general), it propagates into the popular press when those papers are reported on, feeding the wider perception of evolution’s irrelevance in general, and to medicine in particular.  Yet an understanding of how natural selection shapes vulnerability to disease can provide fundamental insights into medicine and health and is no less relevant than an understanding of physiology or biochemistry.MacCallum agreed that the “thrifty gene” concept has fallen into disfavor.  Some other evolutionary ideas are also simplistic: “The relationship between changing environment, diet, and susceptibility to disease, however, is also far from clear.”  Attempts to recreate a Stone-Age Diet “can be misleading,” she said.  Still, she promoted the idea that evolutionary concepts can help medical practice.  Granted, a mechanic may not need to understand the history of technology to fix a car, but an understanding of the evolutionary principles can help prepare for outbreaks of infectious disease, like bird flu, she argued.    Why the resistance to evolutionary teaching in medical schools?  In some cases, it’s the students who rebel:Although Paul O’Higgins thought a comparison of the brachial plexus to the pentadactyl limb was helpful, not all his students agreed—complaints were lodged that he was forcing evolution on them.  That lack of support was also reflected in the participation of only three medical students at the York meeting (albeit enthusiastic ones), despite being widely publicized.  It is not clear whether this is because medical students are more overburdened than most or because of a more deep-rooted resistance to the subject, reflecting wider political and religious prejudice against evolution.So what’s the solution?  “But evolutionary medicine isn’t and shouldn’t be controversial, and the best way to challenge prejudice is through education.”  She took refuge in the famous Dobzhansky quote, “Nothing in biology makes sense except in the light of evolution.”  As an experiment, let’s consider the three cases listed above.  It isn’t very controversial that survivors of lactose, decreased sunlight and oxygen will predominate in those environments, but aren’t they all still human?  Is this really the kind of evolution that Darwin meant?    MacCallum was undaunted by such questions.  “The time has clearly come for medicine to explicitly integrate evolutionary biology into its theoretical and practical underpinnings,” she ended with rhetorical flair.  “The medical students of Charles Darwin’s day did not have the advantage of such a powerful framework to inform their thinking; we shouldn’t deprive today’s budding medical talent of the potential insights to be gained at the intersection of these two great disciplines.”  Convincing the medical students of this may be the hard part.You do NOT want an evolutionary biologist in the room when you need TLC at the hospital.  Lying in bed with pain and weakness, you are not going to look like a fit individual who deserves to survive.    MacCallum again exhibited the shallowness and uselessness of evolutionary thinking.  Notice also the elitist snobbery: anyone who doesn’t agree with the Darwin Party Framework is prejudiced by definition, and must be sent to the re-education camp (cf. 12/21/2005).    Despite the pleas to pul-lease teach Darwin in medical school, medicine is doing fine without the help of Dropout Darwin.  Medicine has a multi-thousand year history that was advanced largely by Christians.  The examples she cited, including the “iconic textbook example” of evolution – antibiotic resistance (dealt a blow by Jonathan Wells in his book Icons of Evolution; see also the Darwinist confession from 09/12/2004) – are all just microevolutionary changes.  The three examples reported above are all microevolutionary changes.  Natural selection at the micro level is not the issue.  Even young-earth creationists accept that.    Such evidence has nothing to do with Darwin’s colossal simplistic generality, the Mystical Tree of Life (02/01/2007).  It has nothing to do with proving that humans have bacteria ancestors, and most medical students and professors know it.  You can almost hear the snickers of students in the classroom when the Prof tells his little fable about how the brachial plexus resembles the pentadactyl limb.  “Right, Teach.  Will that be on the test?  Can I take a pill and call you in the morning?”  Maybe the only way to get a higher turnout than three students at the next well-publicized “Medicine and Evolution” meeting is to award extra credit, provided the students are allowed to bring cots and pillows.    Despite the Dobzhansky rallying cry, things make perfect sense without evolution.  In none of the three cases listed above is Darwin vindicated or needed.  All the humans in those societies are still one species with the rest of humanity, capable of intermarrying and raising children.  What’s more, the adaptive changes observed did not take hundreds of thousands of years.  To the consternation of earlier Darwinists whose ideas are now discredited, the changes fit easily within a Biblical framework of human history.  What is Darwin’s score?  Even MacCallum admits that previous evolutionary ideas like “thrifty genes” have been discarded.  Is anything left that is not controversial and subject to overthrow?  We don’t need Darwin.  We don’t want Darwin.  We want to make sense in the light of the evidence, and help the weak in the process.(Visited 15 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

South Africa beats Senegal in soccer friendly

first_img9 September 2015Bafana Bafana beat Senegal in the Nelson Mandela Challenge, played at Orlando Stadium in Soweto last night. Mpho Makola, in his debut for the national side, scored the only goal of the game in the 78th minute.Coach Shakes Mashaba, who made seven changes to the team following the game lost to Mauritania in an Afcon qualifier on 5 September, will be well pleased with how the players acquitted themselves against a side that had not lost a match since the African Cup of Nations earlier in the year.Bafana produced some excellent football throughout the first half, with Sibusiso Vilakazi and Thamsanqa Gabuza linking up extremely well.The first half ended 0-0.South Africa started the second half much like they had finished the first, pressing for a goal but again wasted numerous scoring opportunities.A breakthrough came in the 78th minute, when Makola received the ball outside the area and unleashed a beautiful right-footed curler into the top-right corner.Senegal had chances to equalise, but a combination of poor shooting and some great work by Itumeleng Khune ensured that the Bafana captain secured the 31st clean sheet of his international career.Although only a friendly, a victory against such quality opposition will surely allow Mashaba to breathe a sigh of relief.Source: News24Wirelast_img read more

South Africa’s judiciary

first_imgFind out more about how the wheels of justice turn in South Africa.The inside of South Africa’s Constitutional Court. (Image: Design Indaba, YouTube)Brand South Africa reporterSouth Africa has an independent judiciary, subject only to the Constitution and the law.The Constitution is the supreme law of the country and binds all legislative, executive and judicial organs of state at all levels of government.No person or organ of state may interfere with the functioning of the courts, and an order or decision of a court binds all organs of state and people to whom it applies.The Constitution provides for the following courts:Constitutional CourtSupreme Court of Appeal (SCA)high courtsmagistrate’s courtsany other court established or recognised in terms of an Act of ParliamentThere are also special income tax courts, the Labour Court and the Labour Appeal Court, the Land Claims Court, the Competition Appeal Court, the Electoral Court, divorce courts, small claims courts, “military courts”, and equality courts.The Constitutional Court, Supreme Court of Appeal and High Courts have the power to protect and regulate their own processes, and to develop the common law.The courts are also required to declare any law or conduct that is inconsistent with the Constitution to be invalid, and develop common law that is consistent with the values of the Constitution, and the spirit and purpose of the Bill of Rights.How are judges appointed?Judges in the various courts are appointed by the President in consultation with the Judicial Service Commission, the leaders of parties represented in National Assembly, and, where relevant, the President of the Constitutional Court.The Judicial Service Commission includes the Chief Justice, the President of the Constitutional Court and the Minister of Justice. It is a widely representative body, with the transformation of the judiciary remaining one of government’s key priorities.Legal systemSouth African law is a combination of different legal systems, with its origin in Europe and Great Britain. Its foundation lies in Roman-Dutch law, which is itself a blend of indigenous Dutch customary law and Roman law. The legal system that prevailed in Holland during the 17th and 18th centuries was introduced to South Africa after the Cape was settled by the Dutch in the 1600s.When the Cape was occupied by the British at the end of the 18th century, Roman- Dutch law was retained and confirmed as the common law of the country. English became the language of the courts and English legal procedures and the English law of evidence in both criminal and civil matters were introduced.As with any other country, the common law has been augmented by statutory law and many of the cases before the court are now concerned with their interpretation and application.Because of the unique heritage of South African law, and the constitutional imperative to regard comparative law, foreign law is frequently consulted, not as binding but as persuasive authority.Judicial decisions are themselves a source of law. The decisions of the court are binding on all lower courts.The Department of Justice and Constitutional Development is responsible for ensuring an accessible justice system that promotes and protects social justice, fundamental human rights and freedoms, thus providing a transparent, responsive and accountable justice for all.Source: South African Yearbook and the Department of Justice.Would you like to use this article in your publication or on your website?

Ohio’s Buehler vying for National FFA office

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Ohio’s candidate to become National FFA Officer for 2017-2018 is Mary Buehler, former president of the Ohio FFA Association. She continues to be in contention for national office.“It’s really neat to transition from state president to national officer candidate,” Buehler said. “A lot of those people that I met throughout my year last year — those members — they are what have inspired me to run as a national officer and I’ve been getting a lot of texts and messages from them as encouragement and I just hope I can represent Ohio to the best of my ability.”Buehler must go through a number of interviews that whittle down the amount of blue corduroy-clad young people hoping to lead the organization over the next year.“It started back in June. I was chosen for a candidate for Ohio so it’s been all sorts of prep and studying since then. I drove to Indy on Friday evening and we started the process bright and early at 7 a.m. on Saturday. I’ve had three rounds of interviews so far and one more to go before we find out who’s going to be advancing on.”Buehler offers advice to FFA members experience the 90th National FFA Convention.“I would say just to soak up the awesomeness that is convention. It’s so empowering to be in such a big sea of blue and to meet people from all across the nation. There’s a lot of really neat people. Lock in that encouragement and inspiration and bring it back home with you.”last_img read more

Microsoft-GitHub Purchase’s Huge Price Tag Belies Big Competitive Worries

first_imgWhat it Takes to Build a Highly Secure FinTech … Adam is a law professor at Michigan State University and directs its IP, information and Communications Law Program. His research interests focus on telecommunications, administrative law, and computational approaches to law. Adam is also a leader in gamification in legal education, designing and producing the first online criminal procedure course that relies on a video game based loosely on GTA. Tags:#Antitrust#GitHub#Microsoft Related Posts How Data Analytics Can Save Lives Adam Candeub Follow the Puck AI: How it’s Impacting Surveillance Data Storage In 2006 Google’s acquired YouTube for $1.65 billion, and Facebook acquired Instagram for $1 billion in 2012.   Many dismissed these purchases as indulgences of cash-rich tech behemoths, and federal regulators took no action.  But, these acquisitions were far from frivolous.  They shut out potential competitors, strengthening Google’s market dominance in search and Facebook’s in social media.And, now Microsoft’s $7.5 billion acquisition of GitHub repeats the pattern.  GitHub is a software company that few people have ever heard of, but on which programmers, developers, and techies depend.  The price tag, which is approximately 30 times GitHub’s annual recurring revenue, suggests that something other than GitHub’s profitability motivates Microsoft acquisition. Indeed, we think than Microsoft could use the personal information and information about software development on GitHub gain even greater dominance of the software industry.  That’s why we started SaveGitHub.com to urge regulators to take a closer look at this deal and impose some conditions to protect consumers and the industry.Why is Microsoft not yesterday’s news? Many people think of Microsoft’s monopoly power as yesterday’s news. Yet while Google, Facebook, Amazon, and Apple have taken over their own niches–Microsoft rivals them all in its overall market capital–currently valued at over $800 billion with a portfolio including Office, Windows, Outlook, LinkedIn, Skype, and Azure’s Cloud services.  Microsoft merges its data from all of these platforms for everything to AI to advertising. While this can help create more efficient products, it also makes it harder for anyone else to compete, particularly in the software market.What is GitHub?When programmers and developers create software, theyneed some place to store the code which project members can access  as well as some way of tracking changed—or a distributed version control system, to use the lingo.  GitHub is the dominant open source platform that provides a repository and version control systems used by programmers to store code and collaborate on projects.What problems could this deal cause?GitHub has emerged as the industry platform for version project members.  Everyone in the software industry uses, including Microsoft’s competitors. It, has emerged as an unofficial social network for the programming community, with personal information creating an indelible record of the world’s top developers work histories and products. Control of GitHub grants insight into how the entire programming world trends—as well as individuals and entities shaping the trending.This could be a competitive problem because as Paul V. Weinstein has written in the Harvard Business Review,  Microsoft  will gain “access to the legions of developers who use GitHub’s code repository products on a daily basis”  so they can be “guided into the Microsoft developer environment, where the real money is made.”Thus, Microsoft’s $7.5 billion offer, approximately 30 times GitHub’s annual recurring revenue, seems makes more sense. By gaining GitHub’s unique insight into programmers and programming, Microsoft will be protecting its dominance in its software markets.What are some common sense remedies federal regulators could impose?Rather than block the merger, federal regulators could impose some simple conditions on the acquisition to protect the integrity of private information and prevent the possibility of Microsoft unfairly leveraging GitHub’s unique position to gain market advantage.Transparency.  Microsoft should disclose any changes it makes to GitHub, its policies, and account requirements–as well as immediately and publicly posting all takedown requests and the resulting actions, if any.  Microsoft should disclose any datamining of the GitHub platform and make results public. It should not sell or disclose developer information to third parties.Neutral Platform.  Microsoft should continue to offer GitHub as a neutral platform for all programs and developers. There must be no preferential treatment for proprietary code or affiliated developers and no discrimination against open source code or developers. By that token, the non-discrimination should prevent using GitHub to promote Microsoft products, or to disparage competitors’. GitHub should not become the Microsoft store or marketing channel.  Github users should be able to “opt in” to communications from Microsoft, rather than being required to opt out of emails and other communication.Privacy.  There must be a “Chinese Firewall” ensuring that GitHub users’ private information is never shared with Microsoft—or with any of Microsoft’s verticals.last_img read more
