K-State Defeats Women’s Tennis

first_imgMANHATTAN, Kan. – The Drake University women’s tennis team played outside for the first time this season on Sunday and fell to the K-State Wildcats 7-0 at the Mike Goss Tennis Stadium.”Our team fought hard through difficult conditions and against a tough opponent. This was our first match outdoors on slower courts and in windy conditions. Playing a team of crafty Europeans made this a difficult match-up. We have a very talented group of players and I’m confident that as we play more outdoor tennis our performance will improve in these types of matches,” said interim head coach John Hollimon.The Wildcats won on courts three and two, securing the doubles point and took a 1-0 lead.K-State used the momentum from doubles to take the first four singles matches in straight sets. The Bulldogs managed to go three sets on courts six and four. Freshman Joely Lomas took the first set 6-4 at No. 6 before dropping the next two sets 6-2, 6-2 to Livia Cirnu at the No. 6 spot. After losing the first set 6-2, senior Maddie Johnson responded by winning the second set 6-2. KSU’s Iva Bago came away with an 11-9 super tiebreaker win to take the third set and the match over Johnson.The Bulldogs travel to Lincoln, Neb. on Saturday, Feb. 27 to square off against Nebraska and South Dakota.Kansas State 7, Drake 0Feb 21, 2016 at Manhattan, Kansas (Mike Goss Tennis Stadium) Singles competition1.

Your Cat and Evolution

first_imgThis week’s just-so story is, “How the kitty got its stripes.”  All the news are on it; they just don’t answer the question.News media are not the least embarrassed to invoke the Kipling just-so story formula, “how the x got its y.”  In this week’s iteration about cat stripes, Live Science headlined, “How the tabby got its stripes.”  Science Daily was a little more creative (or verbose) with, “How the Sub-Saharan Cheetah Got Its Stripes: Californian Feral Cats Help Unlock Biological Secret.”  Even the prestigious journal Science‘s news site got into the act with, “How the Tabby Got Its Blotches.”What the original paper in Science found were genes in tabby cats that, when mutated, form blotches rather than stripes.  Then the research team checked mutant cheetahs with blotches and found the same mutation.  That’s about all.  The paper is by Kaelin et al., in Science, “Specifying and Sustaining Pigmentation Patterns in Domestic and Wild Cats” (21 September 2012: Vol. 337 no. 6101 pp. 1536-1541, DOI: 10.1126/science.1220893).  The most detailed summary was on Science Daily, echoing a Stanford press release, “How the Cheetah Got Its Stripes: A Genetic Tale by Stanford Researchers” (there they go again).“We were motivated by a basic question,” said Barsh of the turn to the study of big (and little) cats. “How do periodic patterns like stripes and spots in mammals arise? What generates them? How are they maintained? What is their biological and evolutionary significance? It’s kind of surprising how little is known. Until now, there’s been no obvious biological explanation for cheetah spots or the stripes on tigers, zebras or even the ordinary house cat.”That’s about all that was said by anyone about evolution: only questions.  None of the scientists or authors explained how these genes “emerged” in the first place.  None of them explained how genes, inside of cells, create precision patterns on the external fur of multicellular mammals.  The press release said that many animals, such as fish and insects, have patterns, but they grow them differently: they add more stripes as the animal grows, whereas your kitten’s pattern will remain the same as it grows to adulthood. That was cause for more questions:“Somehow, cells in the black stripes know they are in a black stripe and remember that fact throughout the organism’s life,” said Barsh. “We were curious about what’s happening at the boundary between light and dark stripes and spots. How do these spots know to grow with an animal?”Even though it is evident that a cheetah’s sports or a tiger’s stripes aid camouflage, nobody explained why some cats are monocolored, some are spotted, some are striped, and some have chaotic markings with no clear function at all.  In short, they promised but did not deliver.So the question is, does Darwin provide a better explanation than Kipling’s?  We learned about a couple of genes, it’s true.  We know that mutations create observable changes in the pattern.  We know the same mutation found in a tabby cat creates a similar change in a cheetah.  But do we know How the tabby got its stripes?  No! – not by evolutionary theory, the explanatory toolkit that is advertised as the great principle that makes sense of everything in biology.  All we know is that when a cat embryo grows, certain genes are switched on and regulated by other genes.  We may know which genes are involved, and how they are regulated, but we still don’t know “How the tabby/cheetah got its stripes.”  Moreoever, we don’t know why some animals have them and others don’t.Think of all the ways Kipling’s story is better than Darwin’s.  It’s amusing.  It’s entertaining.  It can be understood by children.  It’s whimsical.  It’s fanciful.  It has no connection to reality.  Wait– we take that back.  That’s all true of Darwin’s story as well.

Vocals, R&B and soul will be the order of the day, while The Bassline, a hot spot for jazz and blues in Melville, will host “straight ahead jazz”. “Many of our current popular artists had their first performances in front of big audiences at the Joy of Jazz and I am convinced that this year’s event will again unearth some exciting new talent.” Mayor Parks Tau told the City of Johannesburg website: “Through the years, Joy of Jazz has become known for its ability to bring out some of the world’s top performers and this year will be no exception, with Wynton Marsalis as your headline attraction. ‘Unique identity’He added: “Through the years it has built this unique identity by showcasing the wonderful talents of our local jazz greats together with up-and-coming artists from the African diaspora. Besides opening night, Marsalis will also be in action on Saturday, 27 August, on the Dinaledi Stage, which is located at the Mary Fitzgerald Square. The stage will play host to mainstream, afro, and smooth jazz. The twelfth edition of the Standard Bank Joy of Jazz visits eight Johannesburg venues from 25 to 27 August. Emperors Palace will host the opening concert, which features the Gauteng Jazz Orchestra including the African Soul Sisters and nine-time Grammy winner Wynton Marsalis. Show times are from 6.30pm until past midnight. Pulitzer PrizeIn 1996, Time Magazine named Marsalis as one of “America’s 25 Most Influential People”. The following year he won a Pulitzer Prize for Music for his “Blood on the Fields” jazz oratorio. The American presence includes Wynton Marsalis, Frank McComb, Jeff Lorber, McCoy Tyner, Dee Dee Bridgewater, Gerald Veasly and Alexander O’Neal. 17 August 2011 Marsalis headlines this year’s Festival. He’s a versatile performer: a trumpeter, a composer, a bandleader, an advocate for the arts, and an educator. He’s also the Artistic Director of Jazz at Lincoln Center. There will also be three free venues: Sophiatown, Shikisha and Nikki’s Oasis. During his career, he has released more than 40 jazz and classical albums. Situated between the Bassline and Newtown’s Turbine Hall, the Conga Stage will be purpose-built for the festival and will feature world music. It’s a response to the festival being sold out in 2010.last_img read more

How I Process Email Twice a Week

first_imgI respond to every email I receive that requires a response, including responses to my Sunday newsletter. Email takes more of my time than I want it to, but it is still an important medium for communication. Because email isn’t my priority, and by that I mean something that needs to be completed in order to further my goals or projects, it needs to managed well. I go to inbox zero twice a week.First, I don’t live in my inbox. I don’t leave my email program open at all times because it isn’t where I do my work. My work is done in face-to-face meetings, on the telephone, or in Ulysses, the software program I use to write. By keeping my email closed, I am not distracted my new incoming email.Second, I look at my email three or four times a day. If you work for 90 minutes, you can complete a reasonably good amount of work on your most important project. A quick scan at the end of that period lets you check for anything urgent and ensures that you don’t miss anything. If something is really important, someone is going to call you. A quick look, a quick break, and you can go head down for another 90 minutes, or 45 minutes and a 45-minute meeting.Third, I respond to everything that needs an immediate response. That is far fewer emails than you might imagine. It’s something like one in twenty, mostly client-related email. A good portion of the email you get will be things that other people send you because they want you to be aware of something, most of which won’t impact you or your company or your biggest priorities. Much of what you want to respond to can simply wait.Much of your email deserves to wait. If you respond to it immediately and in real time, you are saying that whatever is in that email is more important than your most important priority. You are trading your greatest goal for the goal of answering email.On Wednesday mornings, I process my email, getting all five of my inboxes to zero, replying, archiving, and transferring tasks to my task manager. I repeat this process on Saturdays. In between, I live with a cluttered inbox, free from feeling guilty because I am dedicating my time and energy to my most important priorities.You are a knowledge worker who is living in the Information Age, a time of accelerating, disruptive change. One of the primary decisions you are going to be responsible for making is how you prioritize, and how you focus your attention and energy on meaningful, purposeful work.last_img read more
