Canada’s Lindsay Kellock and Sebastien notched a victory today in the FEI Grand Prix CDI 3* Special, presented by CabanaCoast, topping a class of 13 competitive horse-and-rider combinations. Week five of the 2021 Adequan® Global Dressage Festival (AGDF) concludes on Sunday, February 14, at the Palm Beach International Equestrian Center (PBIEC) in Wellington, FL. The circuit hosts 10 weeks of international and national dressage competition until April 4. Free live streaming and on-demand of select classes are available to view at globaldressagefestival.com.Kellock and the 2006 Rheinlander gelding by Sandro Hit, owned by Enterprise Farm Equestrian LLC and Lindsay Kellock, received a 73.319% from the judges, concluding a momentous weekend for the duo.“I had more confidence going in today based on his performance in the Grand Prix on Thursday,” Kellock began. “He went in and really tried his heart out and gave me a good feeling, which then gave me confidence to ride him a bit more in the ring today. Normally I’m like, ‘Oh, can I do this? Maybe I can push this button?’ but today he just felt so great. I was able to really ride him, take a deep breath, and I think that showed a lot more with those higher scores.”Though the pair didn’t enter an international competition arena for almost 10 months, they spent their time at home perfecting the basics and working on their overall performance together.“[2020 was] a very unfortunate year in many ways,” Kellock explained, “but it was a positive for my horse because he was still green last year. I was really able to work through the training [last] summer and then getting back to work with Ashley [Holzer] in November, ramping up the training then, and having the time to work on weaknesses from last year has been huge for us. We’ve worked really hard at that all summer.”The pair posted a personal best score in the Grand Prix on Thursday with a 72.326% and came back today to earn yet another. “I can’t describe the feeling; it’s amazing,” Kellock admitted. “I couldn’t be happier, and I’m speechless. The horse is an incredible horse, and I’m glad that I’m finally able to bring that out in him.”With Tokyo being their main goal for the year, Kellock will play the rest of the season by ear and focus on what’s best for her mount. “I’m going to go show-to-show with him,” she concluded. “The big plan is to qualify for the Olympics, so I’m going to see how he’s feeling. I think I’d like to do the five star and then after that we’ll see.”Second place in the FEI Grand Prix CDI 3* Special, presented by CabanaCoast went to the USA’s Jennifer Williams on Millione, a 2003 Danish Warmblood gelding by Milan owned by Millione Partners LLC, with 71.979%.

Up to 10,000 people are expected to march through Durban’s city streets, in solidarity with foreign nationals, in the wake of xenophobic attacks in South Africa. The march will be led by KwaZulu-Natal Premier Senzo Mchunu and religious leaders.Foreign nationals have been under attack in the province for the past two weeks.Overnight, police maintained a heavy presence in Durban.Officials say the march will be non-partisan and have called on people from the province to join hands and to fight the prevailing anti- foreigner sentiment.Meanwhile, Malusi Gigaba, South African Minister of Home Affairs has condemned the recent spate of violence, saying it undermined the positive contributions that foreign nationals are making to the country.
The coach’s advice “Keep your eye on the ball” is impossible, because your eyes are constantly in motion with tiny jerks called fixational eye movements or saccades. Why do the eyes move all the time? Some scientists at Boston University decided to find out. Reporting in Nature,1 they found that saccades help you discriminate fine details in the visual field. Rucci et al said,Our eyes are constantly in motion. Even during visual fixation, small eye movements continually jitter the location of gaze. It is known that visual percepts tend to fade when retinal image motion is eliminated in the laboratory. However, it has long been debated whether, during natural viewing, fixational eye movements have functions in addition to preventing the visual scene from fading. In this study, we analysed the influence in humans of fixational eye movements on the discrimination of gratings masked by noise that has a power spectrum similar to that of natural images. Using a new method of retinal image stabilization, we selectively eliminated the motion of the retinal image that normally occurs during the intersaccadic intervals of visual fixation. Here we show that fixational eye movements improve discrimination of high spatial frequency stimuli, but not of low spatial frequency stimuli. This improvement originates from the temporal modulations introduced by fixational eye movements in the visual input to the retina, which emphasize the high spatial frequency harmonics of the stimulus. In a natural visual world dominated by low spatial frequencies, fixational eye movements appear to constitute an effective sampling strategy by which the visual system enhances the processing of spatial detail.The brain compensates for these movements so that we are not aware of them (03/29/2002, 11/24/2005, 11/10/2006). This was known, but the reason for the saccades was only suggestive till now. Using new methods, the Boston University team found that subjects with the stabilized vision lost more than 16% of their ability to discriminate fine details in the high-frequency gratings, but showed no change with low-frequency gratings. This result was unexpected:Thus, fixational eye movements improved discrimination of the orientation of a high-frequency grating masked by low-frequency noise but did not help with a low-frequency grating masked by high-frequency noise. This result is surprising because it contradicts traditional views of the influence of fixational eye movements on vision. Indeed, the pronounced reduction in contrast sensitivity at low spatial frequencies measured by previous experiments with prolonged retinal stabilization predicts a more significant drop in performance with low-frequency than with high-frequency gratings.Nevertheless, their experiments were robust: the saccades helped most in distinguishing fine detail. The researchers found, furthermore, that the eye movement also helped distinguish detail in very low contrast scenes. For a controlled experiment, they kept one axis stable and the other in natural motion. As expected, image discrimination was improved on the moving axis.These results are consistent with the informational content of the modulations of luminance introduced by fixational eye movements. These modulations only convey information about the pattern of noise during motion parallel to the grating, but provide maximal information about the grating when motion occurs on the axis orthogonal to the grating. The authors provided some differential equations that described how the motions of the eye provide more information from the visual field. In conclusion, they said:Our results show that vision is impaired at high spatial frequencies in the absence of fixational eye movements. This finding is consistent with the spatial frequency dependence of the temporal modulations resulting from fixational eye movements. Neurons in the early visual system are sensitive to these input modulations. As with the stimuli of experiment one, natural visual environments possess substantial power at low spatial frequencies. Our results indicate that sampling visual information by means of a jittering fixation is an effective strategy for analysing natural scenes, facilitating the processing of spatial detail in the face of otherwise overwhelming low-frequency power.As indicated, they figured that there must be a function for the phenomenon. This approach motivated them to experiment and find the answer. It was not possible to determine this function with earlier technologies, they said. Science Now weighed in on this story, commenting that these findings “mark an important step toward settling a 50-year-old controversy.” The article said we still have known surprisingly little about saccades. This new work shows that “the eye’s jitters help the brain pick out fine details, the kind involved in locating a single tree in a forest or a berry in a bush.” This ability is shared with other mammals: “Most animals with sharp central vision, such as humans, monkeys, and cats, make microscopic eye adjustments when they fix their gaze.” Saccades have also been observed in the eyes of birds.21Rucci, Iovin, Poletti and Santini, “Miniature eye movements enhance fine spatial detail,” Nature 447, 852-855 (14 June 2007) | doi:10.1038/nature05866.2See Journal of Neuroscience where researchers described saccades in the eyes of two species of predatory birds possessing binocular vision. The authors did not comment on whether this represents a case of “convergent evolution.”There was no mention of evolution in this paper. We do not know their feelings about evolution, but these authors have demonstrated in deed that assuming design leads to productive science. They saw a phenomenon; they assumed there was a reason for it. Now we know more about the eye than we did: and it’s a wonderful thing. There is more information and functional design behind these strange eye movements than we imagined. Their results make sense in hindsight, too (if you’ll pardon the expression). Continuous eye motion allows the neurons and the brain to take numerous snapshots from slightly different angles, so as to glean the maximum amount of information from the visual field. For widely spaced details, this does not add much information, but it adds a lot in low contrast and high-detail situations. Think about that the next time you are reading fine print in low light, like the small black lettering on black plastic that manufacturers are fond of embossing on the backs of TV sets to frustrate consumers when they need to plug in the cable in dim light. Your eyes are subconsciously helping you out. This could have been vital for our primitive ancestors. How could they have plugged in the cable before the flashlight was invented? Compare this finding with the one about birds that bobble their heads when they walk (04/12/2004). When you see something in nature you don’t understand, try the approach that there must be a reason for it. Science is supposed to be an organized method for finding out the reasons for things. Now, ask yourself the meta-question: what is the reason for reason?(Visited 150 times, 1 visits today)FacebookTwitterPinterestSave分享0
Telkom is set to expand its operationsin Africa, with the announcement of apartnership with global telecommunicationsgiant AT&T. Pictured is the Telkom Towerin Johannesburg. (Image: Chris Kirchhoff,MediaClubSouthAfrica.com. For more freephotos, visit the image library.)Janine ErasmusSouth African telecommunications provider Telkom has signed a memorandum of understanding with global giant AT&T. The move will seamlessly connect the two networks on the African continent. The partnership is expected to open up new markets and generate new revenue opportunities.This will benefit African businesses, especially multi-national customers, who will be able to connect more effectively to world markets through the American communications company’s extensive global networks.Making the announcement, Telkom CEO Reuben September explained that the agreement would boost Telkom’s expansion plans and ultimately offer African customers the same quality of voice and data services found in developed countries, but at lower prices.The contract is expected to be finalised within five months. September and his US counterpart, Ronald Spears of AT&T Business Solutions, signed the agreement in Johannesburg in mid-April 2009.Formidable force“This presents a formidable force in dealing with customer needs across the continent,” commented September. “Our strategy is to grow our footprint across the continent, not only through acquisitions but also through partnerships.”“This opportunity is a milestone for AT&T,” added Spears. “Working with Telkom will enable us to extend our world-class IP-based services to sub-Saharan Africa as well as strengthen our ability to serve the needs of customers in the key South African market.”There were various factors that influenced the Texas-based AT&T’s decision to join forces with Telkom, said September. These included the fact that Telkom is now represented in 35 countries through investments in African service providers such as Africa Online and MWeb Africa; it has strong international connectivity, and has a history of strong enterprise relationship.The two companies will collaborate in a number of areas, such as the fast-growing mobile telephony market in Africa, security, teleconferencing, virtual private networks, and data and software hosting. Telkom will focus on infrastructure development, while AT&T will bring its range of products and services as well as international connectivity.Mutual benefitThe American company expects to gain a stronger foothold in sub-Saharan Africa through its partnership with Telkom, said Spears. The company has similar deals in China and the Middle East, both fast-growing regions.Spears added that the ever-improving economic situation in many African regions meant that there were an increasing number of clients that need world-class connectivity in order to be competitive.“Advanced telecommunications networking is a powerful driver of economic growth, prosperity and stability, and an agreement will help progress the availability of and investment in telecommunications services in these countries,” he said.Telkom, meanwhile, is hoping to target foreign firms that are expanding their operations in Africa.The company had been restricted, until now, from offering mobile voice products in South Africa and expanding into Africa south of the equator with anything other than fixed-line services. This was the result of a shareholders’ agreement that concerns Telkom’s 50% ownership of mobile services provider Vodacom.The shareholders’ agreement also affected Vodacom, which was not allowed to offer mobile services in Africa north of the equator. Now the same shareholders have agreed to sell 15% of the company’s stake in Vodacom to the other 50% owner, Vodafone. The deal, said to be worth US$2.5-billion (R22.5-billion), was announced in March 2009 and will give the UK-based company 65% ownership of Vodacom.Vodacom will be converted to a public company and listed on the main board of the JSE Limited, and Telkom’s remaining 35% stake will be unbundled and distributed to Telkom shareholders. Shareholders will also receive 50% of the after-tax proceeds as a special dividend.Vodafone’s additional investment in Vodacom is viewed as a strong sign of confidence in South Africa. It is hoped that the deal will boost competition in the telecommunications sector.Contentious dealAT&T is owned by Texas-based SBC Communications, a former Telkom and MTN investor. In 1997 SBC Communications and partner Telekom Malaysia bought 30% of Telkom, at a cost of $1.26-billion (R5.5-billion at the time). The management agreement was controlled by black empowerment consortium Thintana Communications, formed by SBC (60%) and Telekom Malaysia (40%).In 2004 Thintana announced that it would be reducing its Telkom stake by half, and towards the end of the same year it became known that the management company would pull out of South Africa completely, selling its remaining shares to a government-aligned consortium.Thintana, having recouped its initial investment with the first sale, would leave South Africa with a healthy profit of $950-million (R8.6-billion).Trade union Solidarity expressed its outrage at the situation, arguing that not only had thousands of jobs been lost during the five years that Thintana held sway, but also that Thintana, having made its billions, was removing this capital from South Africa. The deal was also widely slammed because it had guaranteed a five-year period of exclusivity for Telkom and effectively stifled any competition.Spears was confident, however, that the partnership would not be adversely affected by Telkom’s previous relationship with SBC, and that the way is now open for customers to benefit from the expertise that both companies bring to the partnership.Do you have queries or comments about this article?
