first_imgThe body of nine-year-old Imani Leech was on Monday retrieved from Kara Kara Creek at Mackenzie, Linden, following a search led by residents of the neighbouring Speightland community.Dead: Nine-year-oldImani LeechThe area where nine-year-old Imani Leech slipped and fell into the creekLeech went missing after he fell into a section of the Kara Kara Creek in Region 10 (Upper Demerara-Berbice) on Saturday.His partially decomposed body was discovered floating in a section of the Creek at approximately 12:30h on Monday after residents who formed a search party ventured out by boat on the waterway. Following the discovery, Police visited the location and removed the body, which was then transported to a mortuary in the Linden community.Guyana Times understands that Leech, who recently moved with his mother to the Lower Kara Kara, Speightland area, was sitting on a wooden bridge at the Creek with his mother and other relatives some time after midday on Saturday when he “slipped” into the waterway. Relatives told this publication that the child’s aunt, who was sitting next to him, had grabbed his hand, resulting in both slipping into the creek. However efforts to save the duo only resulted in the child’s aunt being saved.“He was on the bridge and he foot get slip and he aunty hold he and all two of them go out together. Plenty people went in the water (searching), because we shout for people. That’s the reason why the aunty get saved,” a female relative had indicated.Searches were conducted for the child by residents and Police thereafter, but yielded no results until Monday’s tragic discovery.“People came and they searched and they say that when the water settle, they will go back and search. Other than that, nothing. We went back and we ain’t see he,” the child’s aunt had told this newspaper.Following the incident on Saturday, the child’s mother, who is a Police Officer, wept uncontrollably.At the scene on Monday, a resident noted that it was “a very sad day” for the community. The child’s mother travelled to Georgetown on Monday to make funeral arrangements. The now deceased child was a Grade Five student of the Regma Primary School in Linden.last_img read more

first_imgQPR boss Mark Hughes is considering a loan move for Porto centre-back Rolando and will complete the signing of Brazil goalkeeper Julio Cesar from Inter Milan in the next 48 hours, the Daily Mail report.It is claimed Rolando has been targeted because moves for Michael Dawson and Ricardo Carvalho have stalled.Meanwhile, Liverpool boss Brendan Rodgers is planning a £15m swoop for Chelsea forward Daniel Sturridge, the Daily Mirror say.It is suggested that Rodgers is ready to sell Charlie Adam and Stewart Downing in order to fund the deal.He is said to be a big admirer of Sturridge, whose future at Stamford Bridge has long been the subject of speculation.Sturridge has made it clear he wants to play in a centre-forward role rather than the wide position he has operated in for much of his time at Chelsea.The Blues are reportedly aware of Liverpool’s interest but would be reluctant to sell unless they sign a striker before this week’s transfer deadline.The Sun say Chelsea want £25m for Sturridge and that Tottenham are also interested in him, while the Daily Mail suggest Rodgers has made an inital enquiry and will try to land the England international for £10m.Chelsea manager Roberto Di Matteo recently stated that he expected Sturridge to stay at the club.The Mail say Chelsea are tracking 23-year-old Montpellier defender Mapou Yanga-Mbiwa.Meanwhile, Tottenham could offer Jermain Defoe to Fulham as part of an exchange deal for Moussa Dembele, according to the Mirror.It is claimed that David Bentley and Jermaine Jenas could also be offered to the Whites as Spurs look to take Dembele to White Hart Lane.Tottenham’s apparent interest in the Belgian is also reported by The Guardian, while the Mail suggest Fulham are monitoring powerful Genk forward Christian Benteke as a possible replacement for Clint Dempsey.This page is regularly updated. Follow West London Sport on TwitterFind us on Facebooklast_img read more

first_imgAnother finding undermines the concept of “junk DNA.”  A team of scientists in Massachusetts found over a thousand functional RNA transcripts from intergenic sequences.  These RNA transcripts, coming not from genes but from regions earlier thought to be non-functional, take part in diverse functions from stem cell pluripotency to HOX gene developmental processes to cell proliferation.    The work by Guttman, Rinn et al was reported in Nature.1  The March 12 issue also included a technology feature highlighting the research of co-author John Rinn of the Broad Institute in Cambridge, Massachusetts.2  The research team developed new methods for identifying the activity of large intervening non-coding RNAs (lincRNAs).  They also found that these RNAs are strictly regulated.    Recognizing that non-coding regions of DNA could be functional has “turbo-charged the field,” he said, “as not only can we identify these things now but we can get a good idea of what they might be doing to test functional relationships.”1.  Guttman et al, “Chromatin signature reveals over a thousand highly conserved large non-coding RNAs in mammals,” Nature 458, 223-227 (12 March 2009) | doi:10.1038/nature07672.2.  N.B., “Technology Feature: Transcriptomics: Rethinking junk DNA,” Nature 458, 240-241 (12 March 2009) | doi:10.1038/458240a.The few mentions of evolution in the main paper are instructive.  One of the methods the scientists used to identify functional RNA transcripts was “evolutionary conservation,” which means the lack of evolution.  Presumably a “conserved” (unevolved) region of DNA or RNA was protected from mutation and selection because it was too functional for Tinker Bell to tinker with.  There is a subset of natural selection called “purifying selection,” which essentially means “defending DNA from the ravages of mutation.”    The researchers found that these previously-unknown functional transcripts were, indeed, highly conserved in mammals: “In sharp contrast to previous collections,” they said, “these large intervening non-coding RNAs (lincRNAs) show strong purifying selection in their genomic loci, exonic sequences and promoter regions, with greater than 95% showing clear evolutionary conservation.”  The team believes there could be many thousands of these lincRNAs in mammalian genomes.    If some of the other non-coding DNA is found to be functional, the implications would be hard on evolutionary theory: “the markedly low rate of conservation seen in the current catalogues of large non-coding transcripts ([less than] 5% of cases) is unprecedented and would require that each mammalian clade evolves its own distinct repertoire of non-coding transcripts.”  That would be too much new genetic information for a Darwinian mechanism to create.  For that reason, they are postulating that most of the RNAs represent “transcriptional noise, with a minority of bona fide functional lincRNAs hidden amid this background.”      The authors did acknowledge one point of logic: “Strictly speaking, the absence of evolutionary conservation cannot prove the absence of function.”  One of their criteria for measuring functionality of lincRNAs was the degree of conservation.  They hedged this criterion by saying, “We do not exclude the possibility that lincRNAs identified by shotgun sequencing that fail to show conservation are nonetheless functional, but other evidence will be required to establish this point.”    To avoid circular reasoning, they cannot use evolutionary conservation as support for evolutionary “purifying selection.”  If absence of evolutionary conservation cannot prove the absence of function, then neither can it prove evolution; the lack of conservation might be due to other causes, like design.  And if a host of functional unconserved transcripts are found, it will seriously call into question the ability of neo-Darwinism to generate a large amount of unique functional information in each mammal genome.    For the time being, Guttman et al are banking on the unconserved stuff being transcriptional noise.  The trend against the “junk DNA” paradigm is against them, however (11/07/2008, 02/06/2008, 09/12/2007, 07/16/2007, and especially 06/15/2007).  One additional thing from the paper is apparent: evolutionary theory was only incidental to the story.  What they were searching for was functional information, conservation, regulation, and the lack of evolution.  In a word, that’s design.  Chalk up another turbo-charged research project to the inherent motivation of ID science: seeking to understand the design in nature.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_img(Visited 20 times, 1 visits today)FacebookTwitterPinterestSave分享0 Was there ever a time when humans were “pre-human”?  Recent finds are overturning assumptions about human ancestors.Antebellum:  Rewrite the story of ape and human brain evolution, advises Science Daily: the “unexpected” speedy expansion of the primate cerebellum was “up to six times faster than anticipated throughout the evolution of apes, including humans.”  So do we classify this story under mammalogy, anthropology, or physiology?  “In humans, the cerebellum contains about 70 billion neurons — four times more than in the neocortex,” Robert Barton of Durham University says.  “Nobody really knows what all these neurons are for, but they must be doing something important.”  That would seem to prompt an investigation based on intelligent design.  Prior to this, the neocortex was considered “the crowning achievement of evolution and the biological substrate of human mental prowess.”  One thing is clear: humans have archaeology; apes do not.  Barton remarked in Live Science‘s article that his findings “turn the story of brain evolution upside down.”  New Scientist got downright Kiplingesque with its panchreston, “Cerebellum’s growth spurt turned monkeys into humans.”Oldest human genome sequenced:  A bone of a modern human from western Siberia, said to date from 45,000 years ago, still had DNA in it.  The sequence, reported in Nature, messes up the old human evolution story, because even way out east, this individual had Neanderthal DNA mixed in his genome.  The interbreeding, scientists believe, must have happened even earlier, as much as 60,000 years ago or more.  This also means that individuals like this one were fully capable of migrating across continents, raising questions about why they didn’t start civilization for so long.  See Ewen Callaway’s news article on the story in Nature.Ten years of hobbit skull-scratching: In 2004, remains of diminutive humans were found in a cave on Flores Island, Indonesia.  They were named (after some dispute) Homo floresiensis, but popularly the “hobbits” because of their short stature.  Despite a decade of study, anthropologists are as confused by the skull, jaw, and various bones as they were then: they have both primitive and advanced traits, but are carbon-dated at 20,000 years old.  Are they examples of Homo erectus, or are they modern humans with a skull defect?  How did they get to this island across the sea?  Ewen Callaway in Nature tells the illustrated story with the major players, and also posted an interview with four key anthropologists.  “Small remains still pose big problems,” Chris Stringer writes in the same issue of Nature.The toolmaker:  “Ancient Stone Toolmaking Didn’t Just Spread Out of Africa with Humans,” writes Charles Q. Choi in Live Science. “An advanced way of crafting stone tools, once thought to have only originated in Africa, may have been invented elsewhere independently, according to a new study.”  This technology dates in the evolutionary scheme to some 200,000 to 300,000 years ago.  But if humans “invented” toolmaking, it didn’t evolve.  That makes it archaeology, not paleoanthropology.  Nature says “evolved independently among different groups of early humans in Eurasia and Africa,” but classifies the article under Archaeology.  The findings were published in Science Magazine.  See also summary on PhysOrg.It’s a long way from Australopithecus to Austria:  “Modern humans may have migrated into Austria 43,500 years ago” reads a headline on PhysOrg.  Logically, that implies they might not have, too, or that when they did, it was not 43,500 years ago but much sooner.  Look for the surprise phrase, “than previously thought.”  Here it is: based on some stone tools found in Austria, “The date of the artifacts represents the oldest well-documented occurrence of behaviorally modern humans in Europe and suggests contemporaneity with Neanderthals in other parts of Europe, showing that behaviorally modern humans and Neanderthals shared this region longer than previously thought.”  Question: did modern humans and Neanderthals have archaeology, or did Neanderthals have only paleoanthropology?  If the former, did the Neanderthals get it by intelligent design?Long way from Austria to the Andes:  A campsite of early Americans high in the Andes puts humans in South America a thousand years earlier than previously thought—12,800 years ago in the evolutionary timeline, reported Science Magazine.  They didn’t even have time to evolve high-altitude survival, but another question might be: what took them so long?  If humans made it to Siberia from Africa, and spread all across Europe and the far East, even traveling by boat, why didn’t they show up in the New World sooner?What’s the point?  The genome of an African man believed to have lived 2,300 years ago was sequenced, but then stories of what he did for a living and where he had migrated from twisted the genetic facts into a tale about evolution.  “What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans?” Science Daily teases, to end with this quote from an evolutionist: “In this study, I believe we may have found an individual from a lineage that broke off early in modern human evolution and remained geographically isolated.”  Are they implying this African was inferior to the Europeans?  Any human living as recently as the times of the great empires was not evolving into anything.Now this is archaeology:  A 3,300 year old complex was discovered at Tel Burna in Israel, PhysOrg reported, complete with walls, utensils and objects that might have been associated with Baal worship often mentioned in the Bible.  In another PhysOrg entry, artifacts from an Iron Age chariot were found.  Objects included a curry comb probably used to groom the horses.  The science of archaeology is the study of remains created by intelligent agents for a purpose: i.e., it is a science of intelligent design.How did paleoanthropology become archaeology?  When did it become history?  What gave humans that extra spark that turned their brains into minds?  Evolutionists have no idea.  They just throw out absurd possibilities, like “Cerebellum’s growth spurt turned monkeys into humans”—(that has to be one of the stupidest headlines in recent memory).  What, did the cerebellum choose to have a growth spurt?  Is the human an accident of some monkey mutation?  Come on, you editors over there, use your brains and stop the nonsense!Evolutionary paleoanthropology is so mixed up, you can’t trust much of anything they say.  Every new story includes the clause, “these findings show that such-and-such was more something-or-other than previously thought.”  In other words, every previous “truth” of paleoanthropology was wrong.  What they believe today is vastly different from what was taught as fact just a few years ago (just one recent example: cave art story from 10/14/14).  Paleoanthropologists love the darkness of their storytelling imaginations rather than the light of logic and the world’s best written record of how man came to be.The absence of artifacts does not prove that humans who left their skeletal remains were incapable of making them.  The presence of simple stone tools does not prove that the creators were mentally incapable of doing better.  There can be other explanations, like isolation from technology of other groups, harsh conditions allowing nothing more than subsistence living, poverty, disease, or personal choices for simple living, like some ethic groups live today—living out their lives by hunting and gathering, leaving no art or literature.  All other evidence shows that humans have always been thinking, reasoning, sentient beings with minds capable of great things, given the right circumstances.  What is outrageously absurd is to believe that upright, migrating, fire-using humans with large brains spent hundreds of thousands of years sitting around in caves doing nothing.last_img read more

first_imgUber vs Lyft: Battling for Supremacy Sales is a difficult job with representatives working long hours to meet demanding quotas while keeping clients loyal and returning for repeat business. While good sales reps remain dedicated to hitting their company’s goals, the chance for employee burnout while doing so is high. There are seven strategies that boost sales productivity.You’ll need strategies that boost sales productivity, as competitors will always be looking to swipe your prospects.Fortunately, sales reps are naturally competitive individuals driven by a desire to win, increase personal excellence, and be their company’s top performer. It falls on sales operations to find the right tools and processes to enable those sales reps to maintain that edge and continue hitting their targets.The following are seven practical tools and strategies sales reps can use to help their reps work more efficiently without feeling the burnout. Ultimately, well-planned strategy will boost productivity and drive your company revenue.Clean and Actionable Sales Performance Management (SPM) DataData must be usable. There is a lot of SPM data everywhere, but until it’s clean, organized, and centralized, it is nothing more than a lot of names and numbers. Ironically, sales data contains some of a business’ most valuable information.This SPM data will provide critical insights into the all-important, but often elusive, customer journey. Much of the sales data has gone unmanaged, and CRM data has taken priority. This does a disservice to organizations since CRM data is subjective and dependent on sales and marketing people to update it.Sadly, both the sales and marketing departments have been responsible for procuring information and adding updates. The habit of having departments with somewhat unique goals — leave inaccurate information in the file. We now have the most erroneous data source in the archives.Companies with large salesforces in highly competitive markets are starting to understand that the data unlocked by their sales performance management (SPM) systems.Your SPM system might hold the keys to the kingdom for your company. The most advanced SPM platforms will already have the capability to pull data in from almost any source in a matter of hours (not days). Use this accurate data accessible to help sales leaders readily identify geographies with ease.Note how quickly you see the potential for business growth and cross-selling productivity opportunities.Combine accessible, accurate data and no-code application development capabilities. That enables quick development of focused reports; sales leaders can quickly and easily activate that data and provide sales reps instant access to the key insights that will help them achieve their goals quickly and efficiently.No-Code Apps Fast and actionable data is crucial for salespeople to close deals quickly. It’s essential for sales people to promptly analyze actionable insights to make more informed and impactful decisions. Sales reps will focus on the right opportunities using no-code data management tools.Gaining instant access to information about customers and prospects in a timely and efficient manner is the key to boost sales.No-code applications enable sales to validate and pre-process data via no-code extract, transform, and load (ETL) capabilities. These capabilities allow the data to be consolidated and organized without sales having to work with additional third-party tools or write complicated code.Automating the time-consuming code writing process enables sales to pull aggregated data in a matter of minutes. You’ll give your salespeople more time to do what they do best quickly and efficiently – sell.Real-Time Performance MetricsIn order to help sales reps succeed and achieve professional satisfaction, they must have visibility into their performance metrics. How many calls are they making? How many meetings have they scheduled? How many deals are they closing?The data shared through SPM data provides sales with this valuable information, allowing them to measure their own performance. Salespeople can see where they want to pick up the pace to close more deals.Sales Pipeline Analysis Sales must perform ongoing analysis of its sales pipeline – tracking opportunities from the first contact to a closed sale. Sales pipeline analysis enables the transactions data to monitor the unfolding sales process and reveal which areas have the potential for improvement.Analyzing the data helps reps achieve their objectives by allowing them to make accurate forecasts based on the number and quality of leads in the sales pipeline. To perform this analysis successfully and to achieve the desired results, sales reps need to identify the pipeline stages in the particular selling process.You’ll see the number of deals in the pipeline, the average sales cycle, win rates, average deal sizes, and even the stagnant opportunities. These stages should flow logically, smoothly leading prospects from one step to the next, all the way to closing the sale.Mobile Alerts and Accessibility Mobile apps are geared toward the always-on-the-go sales rep. They ensure reps get instant access to crucial information about clients and prospects. You’ll facilitate collaboration and communication with managers and colleagues. By using mobile apps to visualize and act upon real-time business metrics, sales reps are empowered to exceed across individual and team goals.Additionally, mobile productivity calculators allow sales reps to gauge their own performance against their coworkers wherever they might be, providing clear, concise “need-to-know” intel that helps them reach their next sales goal quickly.GamificationThe use of mobile apps has also spurred on greater interest in gamification, which is a great tool that resonates well with competitive sales reps who want to win and be recognized for their efforts. With things like leaderboards, gamification naturally taps into this competitive nature. Allow reps to see how they are performing against their colleagues. Gamification can also be used for administrative tasks, like filling out forms and updating sales data. Giving sales recognition for doing these tasks may seem trivial, but it keeps them motivated.CommunicationSales reps want to know how they are performing at all times. As a result, many organizations are increasingly utilizing technology to support those on the frontline.Digital platforms that combine messaging capabilities with incentive compensation systems enable sales operations to inform sales reps. The sales rep needs information about comp plan changes, territories, contests, and other vital matters that affect the quality of their performance.This includes clear communication of targets and goals, ways to close more deals quickly. The reps will learn how to strengthen relationships with customers and turn repeat customers into champions for the organization. Also, sales ops have robust reporting analytics to coach their sales reps in these matters effectively.ConclusionSales reps work hard to earn their compensation year-round. Your reps should be equipped with the tools and strategies that help them hit their quotas, and close those long-lead sales more quickly and efficiently. By using strategic tools that enable them to sell more effectively, sales reps can work more efficiently during the day and hit their organization’s goals, all without feeling the burn.

The State Delegation from Woburn and Wilmington sent a joint letter to the Mass Department of Environmental Protection outlining their objections to the project and asking them to take immediate action. The text of the letter is below.Sincerely,Michael L Raymond, ChairmanWoburn Neighborhood Association++++++++++++++++++++++Office of Heidi ZischGeneral CounselMass DEP 205B Lowell StWilmington, MA 01887Attorney Zisch,We write to you with great concern about the environmental impact regarding the “Ledges” project located at 1042 Main Street in Woburn, MA, and the widespread effects it will have on both the local and regional human and animal populations, forest ecosystem, and groundwater runoff. While we support accessible and affordable housing opportunities in the greater Boston area, the impact the proposed project has on the surrounding neighborhoods in terms of dust, noise, and construction on an environmentally damaged plot leads us to believe that such a project’s negatives far outweigh any perceived benefits. We believe that MassDEP would likely share in our and our constituents justified concerns,Firstly, with 420,000 cubic yards of soil set to be removed, the project not only radically alters the community but also exposes all residents to dust and debris as a result of the extensive blasting. Of particular concern to us is the great amount of Silica dust that will be created. As we are sure you know, silica contributes to increased risks of a myriad of cancers, a heightened risk of OCPD, and is the direct cause of silicosis. These risks are especially concerning due to the presence of young children and the elderly nearby, living in homes not typically insulated against such fine particle matter. Even if such particles do not enter the homes and business of residents, fine particles that land on cars, playsets, and pathways will be directly stirred up and breathed by thousands of people. The National Institute for Occupational Safety and Health recommends that workers who deal with silica change their clothes and park their vehicle in sheltered areas at the worksite, noting that fallen particles on clothes and cars still raise the level for illness. The residents of Woburn and Wilmington do not have this luxury, and instead are forced to be exposed to contaminates without any choice but to abandon their homes. This is egregious.Secondly, we wish MassDEP to address the radical changes such a development will have on the water percolation and runoff, especially with respect to the change in how the plume of the Olin Chemical site has continuously spread. As we are sure you are aware the chemicals leaked from the Olin Chemical property have created a larger plume than previously expected, With the removal of vegetation, top soil, and the creation of thousands of square feet of non-permeable surface we are concerned with the exacerbation that concentrated percolation and drainage will have in extending the plume. By creating non-permeable surfaces and removing topsoil storm-water run off potentially increase in concentration, pushing chemicals spreading through the bedroom even further rather than being held and released more slowly as the current topography of the site allows. As you are also aware, the Wilmington area cancer study is still an ongoing matter, and evidence suggests a correlation between the appearance of rare cancers and the chemicals present in the Woburn/Wilmington watershed.Thirdly, our delegation is concerned about the noise and light pollution on nearby residents. While the area is developed, the lowering of the elevation of the hill and the removal of the trees changes the dynamic of the light and noise pollution tremendously. It is no secret that studies show that exposure to light and sound during evening hours leads to higher rates of stress, depression, anxiety, and more in children. The size and scope of a project that radically alters the landscape will decrease the health of the population, decrease the values of existing property, and compound an already tenuous public health picture.As the project is moving forward, urgent action is greatly needed. We ask that you, within your powers, take into account our objections with the project so that the good people of Woburn and Wilmington do not lose their health, homes, or happiness. As always, if you have any questions on the above points, the project in general, or our other numerous concerns please do not hesitate to reach out to our respective offices.Sincerely,Representative David RobertsonRepresentative Richard HaggertyRepresentative Kenneth GordonSenator Bruce TarrSenator Cindy FriedmanLike Wilmington Apple on Facebook.

first_img Explore further The process involves mixing superparamagnetic manganese ferrite colloidal nanoparticles with individual molecules or monomers that make up the cellulose fibers in paper products or other nonwoven materials and getting them to connect, forming polymers, by submersion in a liquid solution. This process causes a thin shell to form around each fiber. The result is a solution that when applied to paper produces a final product that is both waterproof and magnetic. The team says they’ve also found that the amount of nanoparticles used in the process can be varied to adjust the degree of magnetism the paper will have.By adjusting the kinds of nanoparticles used in creating their solution, the team has found that the resultant paper can be made to demonstrate other properties as well. Using silver nanoparticles for example, allows for creating paper that is resistant to bacteria. Similarly, florescent paper can be made using other substances. There also exists the possibility of mixing up the ingredients to create paper that demonstrates several of the properties, or conceivably all of them at once.While the advantages of waterproof paper are obvious, the team notes that making paper magnetic could be useful for security applications such as when making bank notes or even currency. Also, paper that has antibacterial properties could be used in medical applications or food preparations, or perhaps with currency as well seeing as how many studies have shown that paper money carries all manner of bugs that can make people sick. Florescent paper could be used in security applications but also would likely have a lot of other uses such as in making posters that don’t require a black-light to create eerie effects, documents that could be read in the dark, or as a means of encoding data that only appears when the lights are turned out.The team points out that because the paper as a whole is not being coated, the paper produced from the process retains all of its normal properties. Thus, it can still be written or printed on with normal pens and printers. Also, they say, the solution they create can be applied to paper that already exists, allowing users to change the properties of already printed books, magazines, documents or virtually any other paper product.
