STETHS coach heading to Wolmer’s? … They’ll have to move a mountain to take him – principal

Posted on by

first_imgPrincipal of St Elizabeth Technical High School (STETHS), Keith Wellington, said he has not been informed that his track and field head coach, Reynaldo Walcott, is heading to Wolmer’s Boys’ School and is confident it will take a massive effort to poach his prized coach. As earlier reported on www.jamaica-gleaner.com, Walcott is strongly tipped to take over the reins at the Heroes Circle-based institution after its entire coaching staff headed by Christopher Harley was shown the door following another disappointing season, which culminated in a ninth place finish and 50-point tally at the ISSA-GraceKennedy Boys and Girls’ Athletics Championships. This follows the school’s back-to-back sixth-place finishes in the boys’ section at the 2015 and 2014 championships. Harley was said to have lost the confidence of several influential members of the Wolmer’s community, such as MVP Track Club coach Stephen Francis, who has been a long-time supporter of the programme. “I am confident that it will take a mountain to move him (Walcott) from St Elizabeth Technical,” Wellington told The Gleaner yesterday. “If he is going to move, those interested will have to plan to move a mountain.” Multimillion-dollar contract Sources have informed The Gleaner that Walcott has been offered a multimillion-dollar contract, which represents a 10 times improvement on his current deal with STETHS. Wellington, who praised Walcott for his work over the years in transforming STETHS into one of the strongest programmes in the country, however, maintains that there is no indication that his prized asset will be changing locations ahead of the coming season. The ISSA vice-president added that he has spoken to the coach, who he says informed him of an interest from Wolmer’s, but gave no indication that he will, in fact, be leaving. “I would have spoken to him; he volunteered to speak with me and I still have no information that he is heading to Wolmer’s, whether from the reports or the conversation I have had with him,” Wellington said. “Nothing I have read or heard says he is going to Wolmer’s. I have read where he is the person being targeted by Wolmer’s, and based on the conversation I have had with him, that is as much as I know as well. “… He (Walcott) is the target of their (Wolmer’s) interest, but I don’t know that he is going there,” Wellington noted. Of note, Walcott is currently a member of the MVP Track Club support staff, providing technical support at training sessions and is a feature at the club’s local exercises, overseas camps and international competition. Walcott, who first arrived at STETHS as a 12-year-old in seventh grade, returned to coach the team after four years of study at the University of Technology. He is in his fourth year at the helm of the programme. He is today considered to be one of the best young minds in track and field coaching and was rewarded for his work with head coach duties for Jamaica’s team to the recent Carifta Games in Grenada, where the team won 86 medals. This year, STETHS finished fifth in the boys’ section at Champs with 100 points and seventh in the female section with 71 points. Last year’s effort saw the Santa Cruz-based team also taking fifth place in the boys’ section (132 points) and ninth in the female section (51 points). In the 2014 instalment, STETHS again finished fifth in the boys’ section with 123 points and eighth in the female side on 65 points.last_img read more

Is anybody listening/taking corrective action?

Posted on by

first_imgDear Editor,My good friend and colleague Mr E B John has been painstakingly pointing out the litany of deficiencies within the several branches of the Civil and Public Services of our country. His latest includes a frightening list of maladies in the Public Health Services (ref. his letter in sections of the media). Akin to this has been reports of malpractices leading to severe inconveniences, punishment, discomforts and possibly deaths in public health institutions, as well as other forms of poor public services.The silence from the responsible ‘authorities’ — governmental, public personnel, and political aspirants — has been deafening, and the obvious lack of corrective action begs a multitude of questions as to who really cares about the populace, whose votes are constantly being courted and whose patience must be at breaking point. Can we please see some corrective action, or at least hear some consolation?Sincerely,Nowrang Persaudlast_img read more

Guyanese relegated to drive old vehicles

Posted on by

first_imgDear Editor,The foreign concession class, senior Government officials, remigrants, the ultra-rich and the mafia class in Guyana are the most likely residents to be driving new, economy class vehicles that cost US$25,000 to US$30,000/Gy$6,000,000; or drive Corvettes, Range Rovers, Rolls Royces or Porsches, based on the concessions and financing available to this group.We have relegated working class Guyanese from accessing new vehicles, with the latest technology. The Guyana vehicle tariff regime is antiquated, archaic and visionless, and it has resulted in restrictive and oppressive and irrational vehicle import tax rates. There are many mid-level sedans and non-premium category cars that have over 1999 Cylinder Capacity (CC). Vehicles in this category, such as the Honda Accord, Nissan Altima, Toyota Camry and Hyundai Sonata, will be additionally taxed at Guyana’s world beating vehicle tariff/tax rate of between 247 percent and 297 percent.The vehicle buyer importing a 3000 CC economy class vehicle is asked to pay the same exorbitant tariff as the buyer importing a 6000CC Bentley Continental. It’s only one component of the many malfunction cognitive junctions that permeate our vehicle tariff structure. Is it Government’s policy to reduce fuel consumption and have Guyanese drive low CC vehicles? The vehicles used by our Ministers certainly do not suggest any Government policy to reduce fuel consumption; which is quite acceptable. However, what is unacceptable is the stupendous tariff rates subjected on Guyanese not eligible for duty free concessions. It is not as if we are protecting Guyana’s vehicle manufacturing industry!The Guyanese middle class persons have to consider themselves fortunate if they are able to acquire a vehicle six to eight years old with 2000CC or over. We need to change the current vehicle import tariff structure forthwith. No wonder we have so many illegal schemes to avoid the vehicle tariff, resulting in resources being wasted to manage and implement an outdated and illogical vehicle tariff structure.Henry Ford: “Profits made out of the distress of the people are always much smaller than profits made out of the most lavish service of the people at the lowest prices that competent management can make possible”.Sincerely,Nigel Hindslast_img read more

Liverpool seek to regain title momentum as Man City visit

Posted on by

first_img0Shares0000Liverpool are looking to repeat their strong form over Manchester City last season © AFP / PAUL ELLISLIVERPOOL, United Kingdom, Oct 5 – Liverpool welcome Manchester City to fortress Anfield on Sunday hoping to lay down a marker against the Premier League champions and regain momentum for a tilt at a first title in 29 years.Both sides can only be separated by City’s superior goal difference at the top of the table having dropped just two points each in unbeaten starts to the league season after seven games. However, Liverpool’s perfect run of seven straight wins to begin the campaign in all competitions has come unstuck in the past week.Defeat by Chelsea with a much-changed side in the League Cup was followed by a well-earned point against the same opponents at Stamford Bridge thanks to Daniel Sturridge’s brilliant late equaliser.Yet, more worrying for Jurgen Klopp was an uncharacteristically lacklustre display in losing 1-0 to Napoli in the Champions League on Wednesday.“This was a reality check on how things must not go,” warned midfielder Georginio Wijnaldum.Liverpool were outplayed for large spells in Italy and looked to be feeling the physical toll of a brutal run of fixtures that also included a trip to Tottenham and a thrilling 3-2 Champions League win over French champions Paris Saint-Germain in a four-week spell.“You have seen it has been absolutely intense since the last international break with the games we’ve had — Chelsea twice — coming to Napoli, playing PSG and now we have the game on Sunday against Man City,” said Klopp. “We cannot change that, so we have to make sure we are ready.”– Salah slump –Mohamed Salah scored three times against Manchester City last season, but has struggled to match that form so far this season © AFP / Anthony DevlinCity’s visit, therefore, doesn’t come at the best time as Liverpool seek to show they are capable of knocking Pep Guardiola’s record breakers off their perch.Liverpool had the edge on City when they went head-to-head last season, winning three of their four meetings.City’s hopes of an unbeaten season went up in smoke in a 10-minute period at Anfield in January as Liverpool struck three times en route to winning 4-3.And they also prolonged Guardiola’s quest to land City’s first-ever Champions League title with a 5-1 aggregate thrashing in the quarter-finals.However, the task for Klopp is to marry that ability to rise to the big occasion with City’s consistency that racked up 100 Premier League points last season.Liverpool certainly now have the squad for the long haul. So often outgunned by Abu-Dhabi backed City in the transfer market in recent years, it was the Reds who were the biggest spenders this summer.Of the new recruits, though, only goalkeeper Alisson Becker has made a big impact as Klopp has prefered to stand by those who got Liverpool to the Champions League final last season.That run owed much to the firepower of Mohamed Salah’s 44 goals. However, the Egyptian has so far struggled to match those heights in his second season at Anfield.Salah was subbed off on his return to Stamford Bridge last weekend and largely anonymous in Naples as Liverpool failed to muster a single shot on target.“I don’t remember when that happened last,” admitted Klopp, who remains convinced Salah’s slump will be temporary.“It’s like riding a bike. It’s not like you wake up in the morning and you cannot finish any more.”Liverpool need Salah back in the saddle come Sunday if they are to stop City puncturing their super start by striking first blood in the title race.0Shares0000(Visited 1 times, 1 visits today)last_img read more

Nature Potpourri

Posted on by

first_imgArticles of interest from Nature have been piling up in the CEH queues.  Perhaps a brief mention is better than nothing, before they fall into archive oblivion.Carbon 14:  In the Sept 14 issue, there was a give & take between critics of a carbon-14-dated study and the author.  The critics pointed out, “We appreciate that Mellars’ review was restricted to radiocarbon dating, principally of bone, but it is recommended practice that multiple methods and materials should be investigated to avoid any possible pitfalls that might be associated with a single technique or sample type.”  They decried the need for “much-needed rigour to radiocarbon chronologies.”Bossa Supernova:  Also in the Sept 14 issue, David Branch reported a “champagne supernova” in a star not known to go boom.  “Thermonuclear supernovae were thought to occur only when white-dwarf stars of a certain mass explode,” he said.  “The discovery of a supernova that is way over the mass limit might require a reworking of the model.”  See also the press release from Berkeley Lab.Twinkle, huge star:  Showing that the best proof of a theory in science is existence, an international team said in the Sept 28 issue (pp 427-429), “Theory predicts and observations confirm that low-mass stars (like the Sun) in their early life grow by accreting gas from the surrounding material.  But for stars approx ~10 times more massive than the Sun (approx > 10 solar masses), the powerful stellar radiation is expected to inhibit accretion and thus limit the growth of their mass.  Clearly, stars with masses >10 solar masses exist, so there must be a way for them to form.”  They presented a theory based on non-spherical accretion.Political science:  Environmental activists are another thorn in Big Science’s side.  In the Oct 5 issue, an Editorial began, “Not everyone’s opinion is equally valuable.”  Eco-terrorists who blow up science labs are just the most outspoken of a larger base of support.  Nature advocated dialog with these folks: “signs of paternalism or scepticism about emotional arguments will quickly alienate a section of public opinion whose views, although logically fuzzy, are very firmly held.”  They didn’t say what to do about critics of Big Science whose views are logically sound and very firmly held.Hanging by a string:  The Oct 5 issue had several articles for and against string theory.  The Editors were for it, George Ellis was against it, and Geoff Brumfiel reported the war of words in several new books like Not Even Wrong and The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next.  Ellis reviewed the latter and began, “String theorists are setting a worrying trend by downplaying the need for experimental evidence.”History of science and art:  The Oct 5 issue mentioned an exhibition of the science and art of Leonardo da Vinci touring Europe.Geo-lithium:  How sure are we of the science under our feet?  The Oct 5 issue had a news item beginning, “Lithium isotopes provide a fingerprint of recycled material in Earth’s upper mantle.  But this fingerprint is different from what had been expected.  So do we need to reassess our ideas about how the upper mantle evolves?”Kryptonite-proof superbacteria:  The Oct 5 issue investigated how the tiny germ Deinococcus radiodurans can withstand radiation hundreds of times greater than that required to kill ‘normal’ bacteria.  The secret is in its super-fast and efficient DNA repair mechanisms.  See the Scientific American write-up on this germ.Useful junk:  Two French scientists in the Oct 5 issue (pp 521-524) think junk DNA is an “evolutionary force.”  They said, “Transposable elements were long dismissed as useless, but they are emerging as major players in evolution.  Their interactions with the genome and the environment affect how genes are translated into physical traits.”  It seems odd that a major player in evolution would elude discovery this late in the game.  “But it is an open question whether the variation in genome size is indirectly associated with host population size, or whether it is directly promoted by environmental stress or by the novel environmental conditions that populations encounter when they invade a new habitat,” they said.  “The answer will bear on our understanding of, for example, how ancestral humans adapted after they migrated out of Africa.”  Seems a tall order for junk DNA to explain.Give and take:  Co-evolution was the theme of two articles in the Oct. 5 issue, one by Gavin Sherlock commenting on another paper by Jensen et al.  They considered cell division, discussing the odd observation that while the genes are highly conserved (unevolved) throughout the living world, the expression of these genes is not.  This adds greatly to the complexity of theorizing how the cell cycle evolved, because now the genes and their regulators had to co-evolve; in fact, Jensen et al say, “Our current results raise the intriguing possibility that all three levels of regulation have co-evolved.”  In addition, they discuss the remarkable phenomenon called “just-in-time assembly” in which certain protein complexes only go into action when key proteins are expressed only at the point in the cycle when they are needed.    “It is tempting to speculate on the driving force that leads to the co-evolution,” they said in this paper that, while admiring the complexity observable today, was heavy on speculation about how it got that way.  “Together, our results provide a first global view of the evolutionary dynamics of the transcriptional and post-translational regulation of a large and complex biological system,” they said in conclusion.  But how much can be inferred about evolution?  Not much: “They clearly indicate that although the same general underlying principles, namely just-in-time assembly and multi-layer regulation of functional modules, are widely conserved in eukaryotes, the detailed regulation of individual genes and proteins varies greatly and thus generally cannot be inferred from distantly related organisms.”Zygote to adult:  A book review of Eric Davidson’s The Regulatory Genome by Michael Karin in the Oct. 5 issue dealt with a related problem: “All living organisms deploy similar evolutionarily conserved mechanisms to generate energy, replicate their genomes, use genetic information and synthesize basic building-blocks for their cells,” he began.  “Yet the myriad shapes and forms of both plants and animals are overwhelming in their variety and extremes.  What is even more amazing is that most plants and animals start their life as a single diploid cell (a zygote) created by the union of a sperm and an egg.  How these simple cells give rise to such complex creatures with diverse body shapes is a major preoccupation of developmental biologists.”TRON revisited:  Can life live in a computer?  A German team in the Oct 5 issue investigated biological models in silico.  They recognized that this is not a field for initiatives, and that some traditional biologists are skeptical, they said, “Suspicion towards simulations should dissipate as the limitations and advantages of their application are better appreciated, opening the door to their permanent adoption in everyday research.”  Surprisingly, at the end, “By discovering design principles, identifying biological modules, and quantitatively understanding how they operate through experiments and simulations, we hope to elucidate biological function,” they said.Readers interested in these subjects may wish to pursue the original sources.This illustrates how the reporting here has to be selective just due to constraints of time and space.  Every week, scores of sources and articles from the scientific journals and science news outlets are perused for consideration.  For every article that gets mentioned, dozens more have to be passed over.  We hope you appreciate getting at least a daily digest of interesting and important happenings in a wide variety of subjects related to origins.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
