Victim suffered 8 years of abuse by husband

first_imgNabacalis murderForty-four-year-old Vinetta Headley-James, the mother of eight who was attacked and stabbed to death by her husband on Wednesday afternoon reportedly suffered years of abuse.Vinetta Headley-JamesThe now dead woman was killed at around 12:50h at the Lot 68 Nabacalis, Sideline Dam, East Coast Demerara (ECD) home which she shared with her husband, 45-year-old Sherlock James.Guyana Times understands that on Sunday evening last, the now dead woman was attacked by James, who had reportedly stabbed her to her face and neck, however, she had managed to escape. James had reportedly left the scene of the crime and could not be found.Sherlock JamesHowever, on Wednesday the man returned but to his dismay, he found his wife, the now dead woman, in the process of throwing his belongings out of the house.One of the couple’s daughters told investigators that James requested that his wife cease doing so but the woman refused.This angered James, who reportedly ran into the kitchen, picked up a knife and attacked his wife, this time fatally wounding her to the neck.Headley-James was picked up and rushed to the Nabacalis Hospital, where she succumbed while receiving treatment.James was later discovered lying in a clump of bushes close to the house with a self-inflicted stab wound to his neck. He was picked up and rushed to the Georgetown Public Hospital Corporation (GPHC) where he is presently a patient under Police guard.The police said the incident may have stemmed from an argument owing to the woman’s alleged extramarital affair. However, a neighbour and friend of the woman told a different tale.When Guyana Times visited the woman’s house on Thursday, a relative, Brenda (only name given), recalled that the now dead woman sought refuge at her home on Sunday night during the first attack.According to the woman, she was startled by a loud banging on her door and when she inquired, she saw the woman standing with blood dripping down her body.“She ran over at me with a stab wound here [pointing to face] and one at her neck and then she told me that she small daughter get a stab in her back. I was counselling her, I told her that I don’t like what was going on and I told her that many times this does lead to murder, I [told] she abuse you mustn’t be silent about it, I said speak out about abuse, I had her here until about 02:00h she leave and she went home” the woman revealed.Further, Brenda revealed that during the said time, the now dead woman told her that she faced several years of abuse, which had recently intensified.“She said teacher Brenda, years, years this going on. Abuse, she seh was too much and some incident happened recently and the children them called the father and she said from then to the night that she was at me is abuse all the time, all the time but he ain’t showing it out to the children them like during the day, they even went to church on the Saturday and he telling them that everything would be alright” Brenda informed.The woman told Guyana Times that she was told by Headley-James that problems always arise every time she attempted to seek employment.“She said every time she starts working, he accuses her of having some man, when she starts dressing and making herself nice, is some man.”However, the woman said that on Wednesday, she was doing chores when she heard screams.“It was my daughter calling from upstairs, so when I ran out, I saw her (dead woman) daughter and her baby running over the bridge, so I see like somebody fall into the trench or something but when I meet to the car I saw this woman, her throat was slit and she had something over the neck. My son went into the car with her and I notice her head fall back so I started crying out loud and I realise that she wouldn’t be able to make it” the woman recalled.However, another neighbour and friend of Sherlock James described him as a family-oriented person.“Lowme (perpetrator) is a person that like family, he is a person that would go to the extent to make sure he family get what they need…I don’t know about any issues that they had but I know him for a long time and I know that it had to be something drastic for him to do something like that” the man solemnly explained.

Welbeck double fires Gunners through in League Cup

‘The tie is not over’: Klopp backs Liverpool to recover from Bayern draw

first_imgThe usually free-scoring Reds now face a daunting task in the second leg at the Allianz Arena on March 13.Bundesliga champions Bayern have lost only two of their last 26 home Champions League games, winning 22 of those.But Liverpool boss Klopp is convinced his side have nothing to fear in Germany.“The positive is of course the result is ok, the best draw we can get. Yes we can play better, we should play better,” Klopp said.“The tie is not over. We said that. We had to create the basis tonight that we can use in the second leg.“It was a big fight. We had the bigger chances. It’s not a dream result but it is a good one. We can work with that.”Liverpool’s progress to last season’s Champions League final was marked by a series of swaggering displays at Anfield.But Klopp admitted the well-drilled Bayern defence didn’t allow Mohamed Salah, Roberto Firmino and Sadio Mane to click into gear.“It was not a day when we clicked in the first minute. Bayern are physically very strong and it was difficult to come through,” he said.“We made our lives more difficult with the last pass today.“I don’t know how often, at least 10 times there was a promising situation or a good counter-attack. We immediately shot into their legs, it doesn’t make much sense.“We had our moments but in these moments we have to score. Then the game can change completely.”Klopp had expected Bayern, hit by injuries and suspension, to adopt a cautious approach and the result was a hard-fought but hardly action-packed encounter.“When Bayern are in trouble, they get really serious like this. That was how it was. I didn’t expect them to play attacking football,” he said.“We played against an outstanding side. I’m not over the moon, but I’m completely ok with the result.“It was not a game we will remember in 20 years.”0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Liverpool were frustrated by Bayern Munich in a goalless stalemate © AFP / Oli SCARFFLIVERPOOL, United Kingdom, Feb 20 – Jurgen Klopp insists Liverpool are still firmly in contention for a place in the Champions League quarter-finals despite their dour 0-0 draw against Bayern Munich on Tuesday.Klopp’s side were frustrated by a disciplined Bayern display in the last-16 first leg at Anfield.last_img read more

Family of injured Ramelton man fly to his bedside in Australia

first_imgThe family of a young Donegal man who suffered a serious fall in Australia have flown out to be by his side.21-year-old Shaun Dunworth is in a serious condition in hospital in Sydney.Police found the injured Ramelton man lying on the road under the High Street overpass at North Sydney on Saturday last. It is understood he may have fallen from the overpass or been a pedestrian on the road and was hit when he attempted to cross the road.Local police cordoned off the scene over the weekend and have launched a full investigation into the possible cause of the incident.Shaun was treated at the scene for serious head injury and was rushed to St Vincent’s Hospital in a serious condition.Donegal County Councillor Ian McGarvey is a relative of the injured man. He said Shaun is in a critical condition and everyone is praying that he pulls through.“Unfortunately Shaun has been seriously injured as a result of what appears to have been a fall.“The information his family are getting is not completely clear but he is in a critical condition. He is serious but we don’t know the exact extent of his injuries,” he said.Shaun travelled with friends to Australia earlier this year and is understood to be working there.He had previously worked and lived in Glasgow. Councillor McGarvey said the entire town of Ramelton has Shaun and his family in their prayers.His parents, Karen and Stephen, flew out to Australia today (Mon) to be by their son’s bedside at St Vincent’s Hospital.“You always have concern for young people that go anywhere and you fear the things that might happen to them.“He is well-known in the town and has a lot of friends here and there is widespread concern here for him. “Unfortunately these kind of freak things happen and this is just one of those things.“The family have gone out but only when they get there and report back will there be any accurate information regarding the situation.“It is a very worrying time for the entire family circle and out thoughts and prayers are with them all.“Hopefully, he will make a full recovery but we just don’t know what will happen until the family gets more information,” he added.Family of injured Ramelton man fly to his bedside in Australia was last modified: August 1st, 2018 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:AustraliadonegalfallinjuredRameltonShaun Dunworthsydneylast_img read more

The Future of Biology: Reverse Engineering

first_imgJust as an engineer can model the feedback controls required in an autopilot system for an aircraft, the biologist can construct models of cellular networks to try to understand how they work.  “The hallmark of a good feedback control design is a resulting closed loop system that is stable and robust to modeling errors and parameter variation in the plant”, [i.e., the system], “and achieves a desired output value quickly without unduly large actuation signals at the plant input,” explain Claire J. Tomlin and Jeffrey D. Axelrod of Stanford in a Commentary in PNAS.1  (Emphasis added in all quotes.)  But are the analytical principles of reverse engineering relevant to biological systems?  Yes, they continue: “Some insightful recent papers advocate a similar modular decomposition of biological systems according to the well defined functional parts used in engineering and, specifically, engineering control theory.”    One example they focus on is the bacterial heat shock response recently modeled by El-Samad et al.2 (see 01/26/2005 entry).  These commentators seem quite amazed at the technology of this biological system:In a recent issue of PNAS, El-Samad et al. showed that the mechanism used in Escherichia coli to combat heat shock is just what a well trained control engineer would design, given the signals and the functions available.    Living cells defend themselves from a vast array of environmental insults.  One such environmental stress is exposure to temperatures significantly above the range in which an organism normally lives.  Heat unfolds proteins by introducing thermal energy that is sufficient to overcome the noncovalent molecular interactions that maintain their tertiary structures.  Evidently, this threat has been ubiquitous throughout the evolution of most life forms.  Organisms respond with a highly conserved response that involves the induced expression of heat shock proteins.  These proteins include molecular chaperones that ordinarily help to fold newly synthesized proteins and in this context help to refold denatured proteins.  They also include proteases [enzymes that disassemble damaged proteins] and, in eukaryotes, a proteolytic multiprotein complex called the proteasome, which serve to degrade denatured proteins that are otherwise harmful or even lethal to the cell.  Sufficient production of chaperones and proteases can rescue the cell from death by repairing or ridding the cell of damaged proteins.This is no simple trick.  “The challenge to the cell is that the task is gargantuan,” they exclaim.  Thousands of protein parts – up to a quarter of the cell’s protein inventory – must be generated rapidly in times of heat stress.  But like an army with nothing to do, a large heat-shock response force is too expensive to maintain all the time.  Instead, the rescuers are drafted into action when needed by an elaborate system of sensors, feedback and feed-forward loops, and protein networks.    The interesting thing about this Commentary, however, is not just the bacterial system, amazing as it is.  It’s the way the scientists approached the system to understand it.  “Viewing the heat shock response as a control engineer would,” they continue, El-Samad et al. treated it like a robust system and reverse-engineered it into a mathematical model, then ran simulations to see if it reacted like the biological system.  They found that two feedback loops were finely tuned to each other to provide robustness against single-parameter fluctuations.  By altering the parameters in their model, they could detect influences on the response time and the number of proteins generated.  This approach gave them a handle on what was going on in the cell.The analysis in El-Samad et al. is important not just because it captures the behavior of the system, but because it decomposes the mechanism into intuitively comprehensible parts.  If the heat shock mechanism can be described and understood in terms of engineering control principles, it will surely be informative to apply these principles to a broad array of cellular regulatory mechanisms and thereby reveal the control architecture under which they operate.With the flood of data hitting molecular biologists in the post-genomic era, they explain, this reverse-engineering approach is much more promising than identifying the function of each protein part, because:…the physiologically relevant functions of the majority of proteins encoded in most genomes are either poorly understood or not understood at all.  One can imagine that, by combining these data with measurements of response profiles, it may be possible to deduce the presence of modular control features, such as feedforward or feedback paths, and the kind of control function that the system uses.  It may even be possible to examine the response characteristics of a given system, for example, a rapid and sustained output, as seen here, or an oscillation, and to draw inferences about the conditions under which a mechanism is built to function.  This, in turn, could help in deducing what other signals are participating in the system behavior.The commentators clearly see this example as a positive step forward toward the ultimate goal, “to predict, from the response characteristics, the overall function of the biological network.”  They hope other biologists will follow the lead of El-Samad et al.  Such reverse engineering may be “the most effective means” of modeling unknown cellular systems, they end: “Certainly, these kinds of analyses promise to raise the bar for understanding biological processes.”1Tomlin and Axelrod, “Understanding biology by reverse engineering the control,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0500276102, published online before print March 14, 2005.2El-Samad, Kurata, Doyle, Gross and Khammash, “Surviving heat shock: Control strategies for robustness and performance,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0403510102, published online before print January 24, 2005.Reader, please understand the significance of this commentary.  Not only did El-Samad et al. demonstrate that the design approach works, but these commentators praised it as the best way to understand biology (notice their title).  That implies all of biology, not just the heat shock response in bacteria, would be better served with the design approach.  This is a powerful affirmation of intelligent design theory from scientists outside the I.D. camp.    Sure, they referred to evolution a couple of times, but the statements were incidental and worthless.  Reverse engineering needs Darwinism like teenagers need a pack of cigarettes.  Evolutionary theory contributes nothing to this approach; it is just a habit, full of poison and hot air.  Design theory breaks out of the habit and provides a fresh new beginning.  These commentators started their piece with a long paragraph about how engineers design models of aircraft autopilot systems; then they drew clear, unambiguous parallels to biological systems.  If we need to become design engineers to understand biology, then attributing the origin of the systems to chance, undirected processes is foolish.  Darwinistas, your revolution has failed.  Get out of the way, or get with the program.  We don’t need your tall tales and unworkable utopian dreams any more.  The future of biology belongs to the engineers who appreciate good design when they see it.    It’s amazing to ponder that a cell is programmed to deal with heat shock better than a well-trained civil defense system can deal with a regional heat wave.  How does a cell, without eyes and brains, manage to recruit thousands of highly-specialized workers to help their brethren in need?  (Did you notice some of the rescuers are called chaperones?  Evidently, the same nurses who bring newborn proteins into the world also know how to treat heat stroke.)  And to think this is just one of many such systems working simultaneously in the cell to respond to a host of contingencies is truly staggering.    Notice also how the commentators described the heat shock response system as “just what a well trained control engineer would design.”  Wonder Who that could be?  Tinkerbell?  Not with her method of designing (see 03/11/2005 commentary).  No matter; leaders in the I.D. movement emphasize that it is not necessary to identify the Designer to detect design.  But they also teach that good science requires following the evidence wherever it leads.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read

Chicxulub Crater Reports Begin

first_img(Visited 137 times, 1 visits today)FacebookTwitterPinterestSave分享0 Scientists who drilled into the large crater in southern Mexico have started interpreting the cores.It’s going to be hard to separate the facts from the interpretations for this one. Drill cores from the southern Yucatan crater named Chicxulub are now being analyzed. What do they mean? The news reports freely speculate about unobservable events, mixing fact and fancy according to the current favorite narrative:Dino-Killing Asteroid May Have Punctured Earth’s Crust (Live Science): “After analyzing the crater from the cosmic impact that ended the age of dinosaurs, scientists now say the object that smacked into the planet may have punched nearly all the way through Earth’s crust, according to a new study.”Dinosaur-killing asteroid turned planet Earth inside-out (New Scientist): “An expedition to the Chicxulub crater has drawn a new timeline of how the cataclysmic impact that probably killed the dinosaurs happened – and how it may have carved out new niches in which life could flourish, even in the face of utter destruction.”Asteroid impacts could create niches for early life, suggests Chicxulub crater study (Science Daily): “Around 65 million years ago a massive asteroid crashed into the Gulf of Mexico causing an impact so huge that the blast and subsequent knock-on effects wiped out around 75 per cent of all life on Earth, including most of the dinosaurs.”Dinosaur-killing asteroid’s crater yields new clues (Fox News): “You know the story: About 65 million years ago, a huge asteroid slammed into the Earth, bringing the dinosaur era to an end and creating a massive crater in the process.”Several new memes are emerging from the first reports from the expedition. For one, the impact punched through the crust. A second one says that the impact created new habitats for life. A third one, quite surprising, is that the asteroid strike created “instant Himalayas.” This one, described by the BBC News, is based on physical models of the geological rebound given the assumed size and speed of the impactor.These show how the space impactor made the hard surface of the planet slosh back and forth like a fluid.At one stage, a mountain higher than Everest was thrown up before collapsing back into a smaller range of peaks.“And this all happens on the scale of minutes, which is quite amazing,” Prof Joanna Morgan from Imperial College London, UK, told BBC News.That’s a pretty clear case of catastrophism. The instant mountains are gone, of course, having collapsed. Only traces of the crater remain, detectable indirectly by the kinds of materials, by geographical anomalies like an arc of cenotes and limestone deposits, and by shocked minerals at various distances. Conclusions about the effects on life remain speculative (watch the word “likely”) –The debris thrown into the atmosphere likely saw the skies darken and the global climate cool for months, perhaps even years, driving many creatures into extinction, not just the dinosaurs.While the Chicxulub impact remains the most popular theory for the extinction of the dinosaurs, it leaves many questions unanswered: such as, why did all the dinosaurs (large and small) die all over the globe far from the impact, when many more delicate species, including butterflies, birds and amphibians, survived? Why did it simultaneously erase the pterosaurs and marine reptiles? How could an asteroid impact be so selective about what it kills?At this point, the researchers seem more concerned about testing models of crater formation than answering those questions.It’s good empirical science to drill for cores and study them. Models can estimate energy dissipation if the mass and speed of the impactor are reasonable; these can be tested against the crater evidence. Beyond that, be careful to separate fact from storytelling.last_img read more
