The Region 10 (Upper Demerara-Berbice) Department of Education on Tuesday presented its leg of the biennial Science, Technology, Engineering, Arts and Mathematics (STEAM) Fair, under the theme, “Science, Technology, Engineering, Arts and Mathematics, paving the way for a green and sustainable society”.This year, the Arts have been incorporated into the event, which showcases the innovative skills of students and teachers from schools at every level. Region 10’s exhibition was hosted at the Wisburg Secondary School, Wismar, Linden and featured a host of presentations by students.Linden Foundation presenting their project entitled, “Green Town New Age Eden”Speaking during the opening ceremony for the event, outgoing Linden Mayor Carwyn Holland said he was impressed with the quality of work displayed by the various schools, as he encouraged students to continue to be creative ,”dream big”, step out, invent, and achieve great things.“I believe that your inventive ability should not be confined to this event, but it should be actively utilised…don’t let your creativity be dormant. Dream big and achieve big. If you look around your community you will see many opportunities to be creative,” Holland encouraged.Holland, in sharing his own experiences, further gave encouragement to all to inspire young creative minds to “think outside the box” and become active trailblazers.In an overview of the ever-evolving event, District Education Officer (Nursery) Shivon Greene-Brewster said the objective of the exhibitions has always been to stimulate young minds to analyse and evaluate situations with the aim of exposing students to critical thinking skills.Meanwhile, District Education Officer (Primary) Lashanna Anderson said the activity formed part of the strategy to promote Science and Technology, provide the opportunity for students and teachers to showcase, disseminate and share knowledge relating to these fields.District Education Officer (Secondary) Sonia Fraser-Pearce said the Fair provided an opportunity for creativity as well as the showcasing and sharing of knowledge and skills. The national STEAM Fair will be hosted in Georgetown from April 3- 6, where the winners from Tuesday’s event will be given an opportunity to participate. read more
A Linden man was on Wednesday last jailed for one year by Magistrate Wanda Fortune after he was found guilty of assault, causing actual bodily harm.The sentence was handed down to the defendant, Dexter Thompson, when he appeared at the Linden Magistrate’s court.The court heard that on Tuesday, May 28, Thompson assaulted Onika Sampson at Andyville, Blueberry Hill, Wismar, Linden.
A Donegal entrepreneur has been “blessed” with success since starting his business just a few short months ago.Derrybeg man Connie Gallagher’s novel idea for a long-lasting holy water font captured the imagination when it was launched last November.But since then the father-of-two is working around the clock trying to keep up with orders for his unique design. As well as orders form across Ireland, Connie has branched out into America where he is now supplying EIGHT different religious shops.“It’s hard to keep up now. There are some mornings when I get to bed at 3am and I’m up at 7am to continue working on them.“The profits aren’t huge because a lot of work goes into the fonts which are all hand-crafted.“I’m just delighted to be busy and to be able to carve a living out of them,” he said. Connie first came up with the idea when he noticed the water in most holy water fonts evaporated because of the heat in modern homes.He set about designing a font that holds a reserve of water which dispenses liquid for up to three months when filled.Connie said he has been helped immensely by local priests Fr Brian Ferry of Gaoth Dobhair and Fr Paul Gallagher of Falcarragh.The development of his website www.gallaghergiftware.com has been a huge help with a large number of orders coming from Cork and Limerick.“I’m not sure what it is but we have had a lot of orders from down that part of the country,” said Connie. Well-known Letterkenny businessman Michael Duddy has been helping Connie to get his products known across America.“People have been very good to me and I really appreciate it. Who knows – one day I might even give someone a job. That would be very special,” he said.CONNIE COUNTS HIS BLESSINGS AFTER SUCCESS OF NOVEL BUSINESS was last modified: March 20th, 2012 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)Tags:Connie Gallagherderrybegholy water font read more
Ali Mwebe released a statement awarding three goals and points to Police FC. Photo by Shaban Lubega.FOOTBALL–Last evening, FUFA’s competition department through the director, Ali Mwebe, released a statement awarding three goals and points to Police FC for the game they didn’t play against Masavu FC on Tuesday.According to the referees report, the new comers failed to produce licences for players before kick off of the game with Police FC and so the match was cancelled.As per article 26 paragragh 26.1 in the FUFA competitions, ‘any team that fails to avail licenced player for a particular game will not be allowed to play.’The article further stipulates that, ‘Three points and goals will be awarded to the opposing team,’ and its the same rule that FUFA have used to ensure that Police go top of the league minus kicking a ball.Masavu have been given a deadline of 14- Spetember-2017 to produce licences for all the player although ordinarily, the window for availing players to FUFA is 21 of September.Speaking to Masavu’s head coach Alex Gita, he clarified that the submitted all paper work on Saturday but was suprised with the turn of events on Tuesday.“We submited the National IDs on Saturday because we couldnot get passports from the Internal Affairs offices.“Every Ugandan knows the issues with passports in the country at the moment so i am suprised with qhat FUFA and the UPL have decided.“We accept we lost all three points and we will be looking to get started in our next game.Masavu’s next game is a way to Proline FC on Saturday and hopeful they will have completed the licencing requirments.Comments read more

For years now, evolutionary biologists have been employing “game theory” to try to understand human social behavior. Presumably, game theory applies just as well to robots and ants as it does to humans – any population in which the whole benefits from collective behavior of individuals. The latest example of evolutionary game theory was published in Nature last week.1 Two Japanese scientists with Martin Nowak of Harvard tried to prove that “costly punishment” is inefficient:Indirect reciprocity is a key mechanism for the evolution of human cooperation. Our behaviour towards other people depends not only on what they have done to us but also on what they have done to others. Indirect reciprocity works through reputation. The standard model of indirect reciprocity offers a binary choice: people can either cooperate or defect. Cooperation implies a cost for the donor and a benefit for the recipient. Defection has no cost and yields no benefit. Currently there is considerable interest in studying the effect of costly (or altruistic) punishment on human behaviour. Punishment implies a cost for the punished person. Costly punishment means that the punisher also pays a cost. It has been suggested that costly punishment between individuals can promote cooperation. Here we study the role of costly punishment in an explicit model of indirect reciprocity. We analyse all social norms, which depend on the action of the donor and the reputation of the recipient. We allow errors in assigning reputation and study gossip as a mechanism for establishing coherence. We characterize all strategies that allow the evolutionary stability of cooperation. Some of those strategies use costly punishment; others do not. We find that punishment strategies typically reduce the average payoff of the population. Consequently, there is only a small parameter region where costly punishment leads to an efficient equilibrium. In most cases the population does better by not using costly punishment. The efficient strategy for indirect reciprocity is to withhold help for defectors rather than punishing them.They noted first off that “Human societies are organized around cooperative interactions.” Then they wondered, “But why would natural selection equip selfish individuals with altruistic tendencies?”, adding, “This question has fascinated evolutionary biologists for decades.” Other evolutionists have employed game theory to study the evolution of religion (09/25/2006, 05/27/2008), the evolution of responsibility (11/22/2008), the evolution of patriotism (11/20/2005) and the evolution of altruism (03/16/2005); even weird things like the evolution of spite (01/21/2006). This paper did not address altruism. Instead, they focused on whether costly punishment is effective. They reviewed earlier research with games like Prisoner’s Dilemma that illustrate the outcomes of cooperation and punishment between individuals. After pages of sterile equations and diagrams, they decided punishment is a poor strategy: “The evolution of improved mechanisms of indirect reciprocity therefore leads to societies in which costly punishment between individuals is not an efficient behaviour for promoting cooperation.” This has direct bearing on whether governments should impose costly punishment (e.g., imprisonment) for lawbreakers instead of just withholding help from them. What do their colleagues think of their analysis? An economist and an evolutionary ecologist from Germany weighed in on the paper with a review called, “Game theory: How to treat those of ill repute.”2 They explained the roles of players in the game (think of the parable of the Good Samaritan):When you meet someone needing help, you can help (cooperate), refuse to help (defect) or not only refuse to help but, in addition, decrease the needy person’s wealth (punish). Both cooperation and punishment are costly for you, but respectively create a larger benefit or larger loss for the person needing help. Defection is cost neutral.This makes the Good Samaritan the cooperator, the thieves the punishers, and the priest and Levite who passed by the defectors. But the roles could be redistributed differently in government, a football game, people fighting over parking, or any other situation in which individuals interact. The eight “action rules” of the game also take into account the reputations of the participants and whether the players know those reputations or not. Presumably this includes knowledge of whether others are honest and trustworthy. The reviewers’ own experiments showed a slightly different outcome: people prefer to live in societies that mostly cooperate and defect (i.e., ignore the slight infractions), but that also punish the worst offenders. Other than that, they liked the paper. “Ultimately, study of the joint evolution of social norms and action rules under natural constraints is the goal for the future,” they ended. “Ohtsuki et al. have prepared the ground for that endeavour.”1.

If you thought Social Darwinism went out of fashion in the 1940s, after millions perished from that awful legacy (11/30/2005), guess what: it’s back in new dress. Its practitioners seem less racist and activist but they are just as dangerous. Why? Because their views are completely amoral. There is not the slightest hint of rightness or wrongness in their approach. They speak only of “outcomes” as they play games with human souls. Their vocabulary is morally sterile: preference, equilibrium, strategy, reciprocity, interaction, cooperation, defection, punishment, cost. Human beings are pawns on their chessboard. In their imaginations, this is the “scientific” way to evaluate the evolution of human social behavior. But is it really morally neutral? Is it scientific? No way. Notice the paper’s concluding sentence: “The evolution of improved mechanisms of indirect reciprocity therefore leads to societies in which costly punishment between individuals is not an efficient behaviour for promoting cooperation.” Did you catch the judgment calls? If this were scientifically objective and morally neutral, they would have to reject concepts of improving and promoting certain outcomes. In evolution, whatever happens, happens. There is no light side and dark side. If the human society collapses in a bloody heap, so be it. Jot it down in the lab notebook and move on to the ant farm. Their whole approach tries to be a covering law for any and all outcomes of social behavior. It would not make any difference to them whether the laboratory is Hamas or the Mayflower Compact. Gaza, for that matter, has cooperators (the Hamas terrorists and suicide bombers), punishers (the Hamas leadership) and defectors (the Gaza Baptist Church). The reviewers would have to judge that their ideal society would be to reward the best terrorists and punish the Baptists. Would this not meet their stated goal? – the “study of the joint evolution of social norms and action rules under natural constraints,” they said, where natural is whatever happens, morality be hanged. Then let the reviewers move to Gaza. That is the ideal society to them. They said people preferred to live where cooperation was rewarded and the worst offenders were punished. Don’t be deceived into thinking that this amoral approach to human society is somehow scientific. In the first place, the scientists disagreed with each other. Their standoff required another promissory note: “study of the joint evolution of social norms and action rules under natural constraints is the goal for the future” (as is everything in evolutionary theory). Secondly, it commits the Ratomorphic Fallacy – treating complex human beings as lab rats. Thirdly, it exposes their mental illness known as the Yoda Complex – a delusion of thinking of oneself on a higher plane than the rest of mortals. And fourthly, they plagiarize but deny the existence of the most important word in human government and social relationships: JUSTICE. America’s founding fathers were not just playing games. They knew we all have a “human nature,” but that nature is not naturalistic: it is moral. We have a fallen nature, a selfish nature, a desire to exercise personal freedom at the expense of others. Justice provides rewards and punishments not because it is the best strategy, but because it is a necessity for morally selfish individuals who nevertheless are endowed by their Creator with certain unalienable rights: life, liberty, and the pursuit of happiness (eudaimonia, the responsible satisfaction of worthy goals). One may occasionally find overlap in the Darwinist study with the Protestant work ethic, as stated in II Thessalonians 3:10, “if a man will not work, he shall not eat” (i.e., withhold help from the defector), but for entirely different reasons. The Christian wants the defector to be ashamed of his lack of moral responsibility, while the Darwinist plagiarizes Christian morality by assuming the outcome is “better” for the society when help is withheld from the defector. That difference in motivation makes all the difference in the world. Despite occasional overlap in outcomes, the Christian pursues the strategy because he believes in moral absolutes: good exists and should be rewarded; evil exists and must be punished whether or not the strategy is costly. The Darwinist strategy leads to moral equivalence, because morality is merely a social construction in their world view. Evolutionary game theory, for instance, cannot employ moral judgments in the current conflict between Hamas and Israel, but only determine what is “better” by the outcome. That use of better, however, is loaded with moral overtones. Presumably an outcome is “better” if it is less costly. Says who? Notice how they are assuming that costliness is bad and improved strategies are good. They end up deciding what is better only by plagiarizing and twisting Christian values. In practice, Darwinists usually end up as leftist liberals making moral judgments (e.g., condemning Israel for retaliating against Hamas rocket launches) but on the basis of a morality that cannot be derived from their world view. Bad ideas are precursors to bad policy. Since the Darwinists are defectors from righteousness, they are dangerous and need to be punished. So we offer a win-win situation. Since they love to play games, and need empirical evidence to lend an air of science to their game-playing, give them a lab to work in: prison. The best lab for playing Prisoner’s Dilemma is, after all, a real prison. To get out, they have to “cooperate” with the “punishers” who have the power to set the rules (the rules, remember, are completely amoral according to the Darwin Party’s own definitions, so they cannot complain if they happen to wind up on the losing side). The “action rule” of this game is to state the U.S. Pledge of Allegiance: “I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation, under God, indivisible, with LIBERTY and JUSTICE for all.” Guard, don’t let them out unless they shout JUSTICE with appropriate emphasis. The outcome? They get out, they write up their results in Nature, everybody wins. Defect, punish, repeat as necessary.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0 read more

Basically, what the Council tells you is not to do all those things I’ve shown in my articles, and how to install flex ducts more or less properly. They also refer to standards from other organizations (ACCA, ASHRAE, ASTM…) because this is an installation guide, not a complete reference work. For duct sizing, they refer you to ACCA’s Manual D, for example. Use proper supports to prevent saggingAnother biggie that I see all the time is sagging ducts. The official recommendation from the ADC is that flex ducts should sag no more than 1/2 inch per foot of length between supports.The supports need to be at the manufacturer’s recommended spacing, but no longer than 4 feet. The straps that hold up the flex duct need to be no less than 1.5 inch wide. How to get even better performance with flex ductThe ADC standards provide good guidance for most duct installers. If someone follows them perfectly and the system is commissioned properly, it will probably work fine. The problem, though, is quality control, and one way to help with that is to make it a little harder to do sloppy work. Mike MacFarland, a home performance contractor in California, wrote what may be the best advice ever given in a comment here in the Energy Vanguard Blog:The trick to getting these installations right is to use rigid ductwork for all “deviations from straight,” then pull the ductwork taut between the two ends which now point towards each other. The big advantage over a full rigid installation is sound control — the installations are quieter than fully rigid ones.There you have it. Use flex duct for the straight runs and hardpipe everywhere else. If you really can’t bring yourself to buy those sheet metal elbows, at least follow the Air Diffusion Council standards. Should Flex Duct Be Banned?Raining, Dripping, Crying Duct BootsKeeping Ducts IndoorsWhy Don’t More HVAC Contractors Own Duct Leakage Testers?Duct Leakage TestingSealing Ducts: What’s Better, Tape or Mastic? Pull the inner liner tightOne interesting bit of info that many installers need to understand is that flex ducts need to have the inner liner pulled tight. If it’s not tight, the friction rate jumps significantly, and that means the air flow takes a hit. The diagram below shows that if a flex duct has even 15% longitudinal compression, the friction rate doubles. With 30% longitudinal compression, the friction rate quadruples.An interesting side note to this part of their standard is that when Manual D was being revised for the third edition, the ACCA Manual D group wanted to include information about how poorly installed flex duct affected friction rates, using data from Texas A&M’s research on the topic. According to David Butler, “the ADC lobbied heavily to keep this data out of the book.” ACCA overrode their lobbying, however, and included the data as Appendix 17. I’ve written a lot about duct problems (especially those in flex duct) because they’re so abundant. A couple of years ago, I even wrote an article in the Energy Vanguard Blog about whether or not flex duct should be banned. My answer was no — but that we need better quality control.After I updated and reposted the article recently here at Green Building Advisor, Jack Lagershausen, the executive director of the Air Diffusion Council, sent me a letter.Unlike a certain, very large company that threatened me a while back, the Air Diffusion Council was smart about it. He admitted that the problems I wrote about are “far too common,” and sent me a complimentary copy of the Council’s installation guide, Flexible Duct Performance and Installation Standards.Today, with the hope that some readers will act on this information, I’ll give you a bit of an overview of this guide, and will encourage HVAC companies looking to do a better job of installing flex duct to invest the $15 and get a copy. Then use it to train your installers. A few tidbits from the ADC standardsThe 25-page guide begins with a description of the classifications and characteristics of flex duct, then discusses how they’re tested, listed, reported, and certified. Chapter 4 is where the meat of the manual is — the installation details — and that’s the part I’ll talk about here. Don’t make sharp bendsAnother problem that I see frequently is bends that are too sharp. The ADC standards say, “Keep bends greater than or equal to one (1) duct diameter bend radius.”The language is a bit clunky, but the diagram below shows what they mean. If you can put an equal size duct inside the turn, as shown below, they say you’re OK. (You can see my thoughts on this below.) How to make connectionsThe ADC standards give a lot of other details about installation, including one of the most important aspects: the connections. The skinny on that is to make sure you get a good, solid connection between the inner liner and the connector, seal it with mastic or tape, and then bring the insulation and outer jacket over the connection and seal it, too.One more little note about those connections: The first method they show is to connect the inner liner mechanically with a metal clamp. These are the ones you see holding the rubber hoses onto their connectors in engines, with a screw that you turn to make them tighter. I’ve never seen one of these in the field, except on a couple of my own small retrofit installations. They also show how to attach the inner liner with sheet metal screws, but I wouldn’t do that with flex.Interestingly, the fastener that’s used most often, plastic zip ties, is only mentioned in the footnotes: “Nonmetallic clamps shall be listed and labeled in accordance with standard UL 181B and marked ‘181B-C’.” RELATED ARTICLES A word about costThe main reason we see so many bad installations is expense. It costs more use the right methods. It costs more to train employees to do it right. It costs more to use materials that are harder to mess up. It costs more to do proper design and commissioning.The truth is that there are costs associated with doing it wrong, too. It’s just that the homeowner usually bears those costs. My friend Robert Bean recently posted an article about the cost of HVAC systems, which he prefers to call indoor climate systems. The chart below is from that article and gives you a feel for how much bang you’re getting for your buck. Of course, Robert’s Canadian, so you’ll have to convert using the current exchange rate if you’re not in the Great White North. ;~)You really should go read his article because Mr. Bean is one of the most knowledgeable HVAC guys around. Check out the rest of his website, too. There’s a wealth of information there.The bottom line in all this is that you get what you pay for.
