Amphitheater-shaped canyons are common throughout the West – and even on Mars. Geologists had them pretty well figured out. Water seeps out the bottom of a wall, weakening the face of a cliff. Gradually, material collapses and leaves a large alcove that continues to recede headward. That idea is now questioned by a new theory that says catastrophic flooding produces these canyons suddenly. Space.com has a summary of a paper published in Science this week that re-evaluated a classic case, Box Canyon in Idaho. The new theory is that sudden flooding, perhaps from melting ice sheets to the north, released a torrent of water that cut the canyon at one time. The article estimated the complete canyon, cut into solid basalt, was eroded in 35 to 160 days at most. The flood theory explains unusual features, like scour marks on the walls and large boulders sitting out in the middle of nowhere, that were difficult to explain with the old theory. An idea of the size of this “megaflood” was given in the article. Michael Lamb, geomorphologist at UC Berkeley, said, “Imagine forcing a quarter of the flow in the Mississippi through a chute 32 times as narrow and 1,000 times as steep as the Mississippi River channel.” 800 to 2,800 metric tons of water could have blasted through the channel at 22 miles per hour. Space.com reported this article because of its implications for Mars research. If megafloods also formed the amphitheater-shaped canyons on the red planet, perhaps calm water did not exist for long periods – a blow for those hoping life would have time to exist.Another old-age paradigm has had to shift under new investigation. These kinds of canyons are very common in the arid southwest, like in the Grand Canyon. Where did the water come from in the desert? In the aftermath of a worldwide flood, such phenomena would be expected, but not in a place where geologists feel huge seas of Sahara-like sand ruled for millions of years. Access Research Network also reported on this paradigm-shifting theory.(Visited 26 times, 1 visits today)FacebookTwitterPinterestSave分享0
29 August 2016Approaching the right investors and the characteristics of a good or badinvestment were discussed in How to Get Deals Done, one of the knowledgesessions held on the first day of the Demo Africa 2016 conference in Johannesburg.At the two-day event, held at the Sandton Convention Centre on 25 and 26August, entrepreneurs and investors from all over the continent were networkingand sharing insights into the tech industry.The event was hosted by Lions Africa in collaboration with the City ofJohannesburg, the Department of Science and Technology, Google, Intel andMicrosoft.Some of the investors said: “The cheapest investment is to just bring cash.Access to business networks is another way of being part of an investment deal.”PresentationsThe organisers said that this year, 723 tech entrepreneurs from 27 Africancountries applied to be part of Demo Africa. Of these, 30 entrepreneurs werechosen to present their businesses to local and international investors at theconference.The entrepreneurs included Rodney Kuhn of Sortd., a Johannesburg companythat designed an app to help businesspeople organise their lives and work throughtheir emails.Other start-ups at the conference included Art Nigeria, an online company thatsells the work of Nigerian artists globally. This artwork can be in the form of a mug,a throw pillow, a duvet or on a frame.Mum’s Village is an online platform that gives information to pregnant womenin Kenya.Owners of all the startups were given six minutes to pitch their businesses toinvestors and judges on the two days of the conference.The judges then gave their opinions on the presentation and offered advice.Through this, the startups stood a chance to get funding for their businesses.The boot campTwo days before the conference began, 27 tech entrepreneurs took part in aboot camp hosted by Demo Africa. During this, they received coaching andmentoring on how to pitch to investors.“The Demo Africa boot camp is a continuation of an online mentoring andcoaching process we have in place for the finalists,” said Harry Hare, executivedirector of Demo Africa.The online programme ran for four weeks and was concluded with the bootcamp.The process of mentoring and coaching was vital for many of theseentrepreneurs, said Hare. “Our experience has shown us that the Demo Africafinalists are at different development and maturity levels within their businesses.“A lot of them are also technically minded rather than business-minded, so werefine them to think more about their business and what they are offering toinvestors,” he explained.Stephen Ozoigba of the African Technology Foundation was one of the mentorsat the boot camp. He said 30% of the startups in the finalists’ group were led bywomen.He encouraged the attendees to support their local startups, especially thoserun by women. “It’s important that we empower women.” The 27 Demo Africa 2016 finalists were part of a two-day boot camp withmentors. (Image: Demo Africa 2016)Advice on making dealsIn the How to Make Deals session, Ozoigba said designation was importantwhen approaching an investor. “Some cities are more favourable.”He spoke about issues that could cause an investor to stop funding a business.One of these was lack of structure, which could lead to your losing a deal with aninvestor. “It’s good to learn governance early [about how business works]. Comeinto board meetings and learn how things work.“For example, learn about what voting is in a board meeting.” At Demo Africa 2016, Stephen Ozoigba (right) of the African Technology Foundation says everyone should support their local startup. Liew Claasen (left) was also part of the discussion. (Image: Melissa Javan)It was important that owners of startups understood the legal status of theentity, said Tomi Davies of the African Business Angels Network. “Before making adeal with an investor, decide who will get the money that you will make.”Their process as investors was simple, said Liew Claasen of Newtown Partner.“You first send out the application to us. We then meet face to face if we think wewant to invest into your business. It helps us to make consistent decisions.”Mistakes some entrepreneurs made were that they did not communicate muchwith the investor after they got the capital, he said. “Post-deal communicate a loteven if you feel this person is too important and busy.“A bad investment is when [the startup] doesn’t give updates [to the investor].We must have a good relationship. Your relationship with your investor will alsosend out a message to the next investor about you.” A panel at Demo Africa in Johannesburg on 25 and 26 August 2016 on How DealsAre Done gives advice to entrepreneurs on dealing with investment partners.(Image: Melissa Javan)Other knowledge sessions included Venture Growth Strategy.Insightful eventEntrepreneurs such as Innocentia Msimango said the conference was an eye-opener for her. She is the owner of a food distribution company called Cyber MobiRoyal Kitchen. Her staff cooks food for clients, which the company then delivers.Msimango said she did not have an idea about what investors sought. “Thisinformation gives me hope.“Not only will I get capital, but heartfelt support of experience. I find itencouraging that there are people wanting to help us.”The conference gave quite refreshing insights, said Donovan Nadison of theBusiness Place Network. “The information here is about how to deal with andmanage complex small businesses support issues.“It confirms to me that South Africa is on the right track. We have expertise indealing with SMME issues that are complex… Everyone can benefit from thenetworking done here.”There were 500 attendees at the conference. The Global EntrepreneurshipCongress will be held in March 2017 in Johannesburg. One of the objectives of thisconference is to brand the City of Gold, as Joburg is known, and the whole of Africaas an investment destination.Would you like to use this article in your publication or on your website?See Using SouthAfrica.info material
