Four seniors named Rhodes Scholars

first_imgFour Harvard undergraduates are among the 32 American men and women chosen as Rhodes Scholars on Saturday. They will begin their studies at the University of Oxford in October 2012.All from the Class of 2012, Harvard’s newest Rhodes Scholars are Brett Rosenberg of Chappaqua, N.Y., Spencer Lenfield of Paw Paw, Michigan, Samuel Galler of Boulder, Colo., and Victor Yang of Lexington, Ky.Arguably the most famous academic award available to American college students and graduates, Rhodes scholarships every year attract hundreds of top students. The 2012 American Rhodes Scholars faced competition from 830 students nominated by 299 colleges and universities nationwide. This year’s awards bring the ranks of Harvard’s Rhodes Scholars to 336.Created in 1902 by the will of British philanthropist Cecil Rhodes, the scholarships cover all costs for two or three years of study at Oxford. Winners are selected on the basis of high academic achievement, personal integrity, leadership potential, and physical vigor, among other attributes.To see a complete list of the 2012 Rhodes Scholars and read the winners’ bios, visit the Rhodes Scholars  homepage.last_img read more

Easier Decisions Through Better Computer Storage Classification

first_imgWhen naming their “Best Business Laptops of 2017,” PC Mag noted that the right desktop can mean the difference between your company running smoothly and not running at all. This can be especially true for a creative professional running a small business that needs the high performance of a workstation.And, more than ever before, today’s workstations come in an incredibly diverse assortment of form factors with a range of storage options. It can be confusing to determine what you need.So our team developed a white paper to help you decide on the best storage option for your systems, in terms of performance, without needing to consult a technical guide on the architecture of modern SSDs.Lost you already? Let me step back a bit.In the days before solid-state storage devices (SSDs), the complexity of storage usually revolved around whether and what type of redundant array of independent disks (RAID) to use in your systems. Rotational hard disk drives (HDDs) improved in performance and predictability over so many decades, that the selection criteria for these kind of drives narrowed to capacity and rotational speed as performance within these categories was so close between different drives.As SSDs became more broadly available in lower-priced and higher-capacity packages, we started to see some peculiar performance patterns. Most everyone knows that with each generation the performance was increasingly dramatically in SSDs, distancing them further and further HDDs and exceeding the bandwidth of the SATA III connection. But these “growing pains” had a side effect: increased variation across SSD models. While the same model might provide very consistent results across many different samples of the same drive, different models (especially across different drive vendors) were showing dramatically different performance at the same capacity and using the same interconnect.Now, much of these differences can be explained by the ingredients inside the SSD – things like the flash type and the controller, or even the bus connection and device protocol. But the complexity of the internal components of the SSD are not something that most workstation customers should have to concern themselves with. They need a better way to distinguish the various devices beyond capacity; something that is relevant to the ways that they use the system in the real world.Ready to go even deeper now? Dive into our white paper. And feel free to hit me with questions in the comments below.last_img read more

BioNTech and Pfizer’s COVID-19 vaccine shows potential in human trial

first_imgA third dosage, tested at a higher concentration in a separate group, was not repeated after the first shot because of injection pain.”These first trial results show that the vaccine yields immune activity and causes a strong immune response,” said BioNTech’s co-founder and Chief Executive Officer Ugur Sahin.He said larger trials were being prepared to show whether this translates into protection against a real infection.”While more work needs to be done, we believe the benefits appear to outweigh the risks so far, especially when considering the disease the vaccine is trying to prevent,” Mizuho Securities analyst Divan Vamil said in a note.Peer reviewNo COVID-19 vaccine has yet been approved for commercial use. A Massachusetts Institute of Technology analysis last year found that about one in three vaccines in the first stage of testing later gains approval.BioNTech, which listed on the US Nasdaq in October, said the data demonstrated that BNT162b1 could be administered in a dose that was well tolerated with only temporary side effects.Early-stage human trials of vaccines are designed to measure certain antibodies and other immune markers in the blood as an indicator of the body’s readiness to fight an infection that then requires further validation.The pharmaceutical industry is eager to launch larger follow-up trials to see how vaccinated participants react to real infections over longer periods.BioNTech and Pfizer will now pick the most promising of four experimental vaccines for a trial involving up to 30,000 healthy participants, which is likely to begin in the United States and Europe in late July, if it gets the regulatory green light.If it eventually gets marketing approval, the companies are gearing up to make up to 100 million doses by the end of 2020 and another 1.2 billion doses by the end of 2021 at sites in Germany and the United States.Results from early-stage testing of BioNTech’s three other potential vaccines have yet to be published.The manuscript with the preliminary data from the clinical trials, which were launched in April and May, is under peer review for publication in a scientific journal, BioNTech said.Singapore’s state investment fund Temasek and other investors said on Monday there were investing $250 million into BioNTech for a 1.1% stake in company.The Mainz-based company is using the so-called messenger RNA approach, like unlisted domestic rival CureVac and Moderna. Translate Bio and its partner Sanofi are also working on a messenger RNA vaccine for COVID-19.Biotech investors Thomas and Andreas Struengmann, who sold their generic drugs business Hexal to Novartis in 2005, are major shareholders of BioNTech. BioNTech’s shares were up 4.6%, after rising as much as 19% to reach their highest in more than three months.Pfizer stock also gained, rising 4.4% to $34.13. In turn, shares in some rival vaccine developers, such as Moderna and Novavax Inc dropped.BioNTech said testing of two dosages of its BNT162b1 drug on 24 healthy volunteers showed that after 28 days they had developed higher levels of COVID-19 antibodies than typically seen in infected people.It said the higher of the two doses – both administered via two injections within three weeks of one another – was followed by a short fever in three out of four participants after the second shot. Topics :center_img A COVID-19 vaccine developed by German biotech firm BioNTech and US pharmaceutical giant Pfizer has shown potential and was found to be well tolerated in early-stage human trials, the companies said on Wednesday.The drug is one of 17 being tested on humans in a frantic global race to find a vaccine the world is counting on to end a pandemic that has infected 10.5 million people and killed more than half a million so far.The potential treatment is the fourth early-stage COVID-19 drug to show promise in human testing, along with projects involving Moderna, CanSino Biologics and Inovio Pharmaceuticals.last_img read more

NBA Draft: How Chris McCullough fits into the Brooklyn Nets rotation

first_imgFormer Syracuse forward Chris McCullough was taken with the No. 29 pick in the 2015 NBA Draft by the Brooklyn Nets. The hometown fans at the Barclays Center chanted his name before the pick and they got what they wanted.Here’s the Nets’ current contract layout, courtesy of Basketball-Reference.com:McCullough, a 6-foot-10, 220-pound forward, joins a roster that has seven forwards/centers, most notably Brook Lopez. Mason Plumlee also got significant playing time down low for Brooklyn, but was traded to the Portland Trail Blazers on Thursday night. The other five big men on the roster have contracts that expire in the next one or two years.ESPN analyst Jay Bilas said McCullough may benefit from some time in the D-league, but time will tell if he cost himself an initial NBA roster spot by leaving after one year of college.AdvertisementThis is placeholder text Comments Published on June 25, 2015 at 11:15 pm Contact Matt: [email protected] | @matt_schneidman Facebook Twitter Google+last_img read more

Sho’t Left targets Moz, Botswana

first_img29 August 2008South African Tourism has broadened the focus of its Sho’t Left campaign, which encourages South Africans to travel more within the country, to target up-and-coming youngsters from Botswana and Mozambique.“Thousands of Mozambicans visit South Africa every year to trade and so business,” South African Tourism CEO Moeketsi Mosola told BuaNews in Johannesburg this week.“We have broadened our focus to emphasise tourism and leisure to the people of Mozambique.”He said that travellers from Botswana were among the biggest spenders in South Africa, adding that the new campaign would help refocus visitor spending toward the local tourism and hospitality industry.South Africa is visited by 4.5-million travellers from the Southern African Development Community a year, injecting massive amounts of capital into the economy, creating thousands of employment opportunities.Tourism, meanwhile, is one of the biggest growing sectors of the South African economy and is set to grow massively in the build up to the 2009 Fifa Confederations Cup and 2010 Fifa World Cup.Increasing affordabilityMosola said that one of the fundamental aims of the campaign was to make was to make travel and tourism affordable to ordinary South Africans, pointing out, for example, that the high cost of visiting areas like the Eastern Cape or Mpumalanga provinces discouraged South Africans from travelling within their own country.It was important for South Africans to visit various attractions around the country because travelling had the ability to break down barriers, Mosola said, adding that it allowed a person to learn something about themselves, their friends, and family.“That is why we emphasise travelling must not be done alone, but must be done with friends.”Packages put together by South African Tourism go from as cheap as R180 to whatever a person’s pocket can afford, Mosola said.Travel experiencesAs part of the campaign, television advertisements featuring the travel experiences of groups of friends from South Africa, Botswana and Mozambique in South Africa, are being broadcast on South African Broadcasting Corporation’s SABC 2 channel.Brad Harrison, 26, from Johannesburg, featured on one the TV advertisements. He told BuaNews that he was a nutritionist who was roped into being an ambassador for the campaign by one of his friends.Harrison, who travelled to Mpumalanga with two of his friends, embarked on a series of blood-pumping activities including quad biking, bungee jumping and gorge swinging, game drives and canopy tours.“It was one of those experiences which opened up my eyes to the experiences available out there,” he said, adding that by being a nutritionist, he was able to identify the problem with a lot of South African kids.He said they were watching too much TV or playing electronic games and not getting out enough. “Youngsters out there need to get off the couch and travel this country of ours.”Harrison further said it was important that this campaign spread Botswana and Mozambique as “we are all part of Africa and we need to unite”.Source: BuaNewslast_img read more

South Africa to procure still more renewable energy

first_img15 April 2014 South Africa’s Department of Energy is to increase the amount of energy it will be procuring under the third window of its renewable energy programme for independent power producers, Energy Minister Ben Martins announced on Tuesday. In November, the department signed agreements with 17 new preferred bidders in the third round of the programme, following the signing off of 47 projects in the first and second rounds, bringing to 64 the total number of renewable energy projects approved by the government since December 2011. Once they are all operational, the 64 projects – representing foreign and domestic investment of over R100-billion – will add around 3 900 megawatts (MW) of wind, solar photovoltaic and concentrating solar power to South Africa’s energy mix. On Tuesday, Martins said in a statement that this department would be allocating additional megawatts to the third window of the programme, thus including additional bidders, due to the increasingly competitive pricing offered by the round three bids. Business Day reported in November that the average price offered for power generated from wind – which received the bulk of the third-round allocation – had dropped from R11.43 per kilowatt hour (kWh) in the first round to R6.65/kWh in the third round. “The department will, in this regard, follow due procurement process to include additional bidders under window 3,” Martins said, giving no further specifics. He added that submissions for the fourth window of the programme, which entails the procurement of a further 1 000 MW of renewable energy, was on track to close in August. The programme has five windows altogether. While renewable energy accounted for less than 1% of South Africa’s energy mix in 2012, this is expected to reach 12% by 2020. According to research released in October by analysts Frost & Sullivan, this would place South Africa in the “global top 15 countries” with regard to the implementation of renewable energy projects. Announcing the latest 17 preferred bidders in November, Martins noted that South Africa was currently rated as the 12th most attractive investment destination for renewable energy. “This bodes very well for South Africa, as the programme has achieved international acclaim for fairness, transparency and certainty of programme,” Martins said, adding that there had been a progressive increase in the local content and job creation numbers offered by the bidders. The department’s director-general, Nelly Magubane, said that some bidders had exceeded the local content requirement of no less than 40%, with some indicating that their projects would involve up to 56% local content. Martins said the energy sector was expected to play a major role in creating green sector jobs, developing skills and transferring technology into South Africa’s economy.

Finding Better Friends: Delicious and SPEAR

first_imgTags:#Social Bookmarking#social networks#web The Dos and Don’ts of Brand Awareness Videos A Comprehensive Guide to a Content Audit dana oshiro Guide to Performing Bulk Email Verification Related Posts Facebook is Becoming Less Personal and More Pro… Between self-aggrandizing FriendFeeds, bottom-feeding link baiters, and perpetual Twitter spammers, finding cool online friends can be challenging. Michael G. Noll and Ching-man Au Yeung created the SPEAR (SPamming-resistant Expertise Analysis and Ranking) algorithm in the hopes of separating the social media wheat from the chaff. This morning the two postgraduate students offered their findings to Delicious in a blog post. The project was first evaluated using data sets collected from the popular bookmarking community. Noll and Yeung presented SPEAR in a paper entitled, Telling Experts from Spammers: Expertise Ranking in Folksonomies at July’s SIGR Conference. The solution is based on the information retrieval algorithm HITS (Hyperlink-Induced Topic Search), an algorithm best known for powering Google and Yahoo web page rankings. Rather than producing search results, SPEAR ranks and produces a list of experts and content. According to the duo, their method is more resistant to spammers for the following reasons: 1. Mutual reinforcement of user expertise and document quality: A user’s expertise in a particular topic depends on the quality of the documents she or he has found, and the quality of documents in turn depends on the expertise of the users who have found them.2. Discoverers vs. followers: Expert users should be discoverers – they tend to be faster than others to identify new and high quality documents…SPEAR gives more credit to users the earlier they find high quality documents. After analyzing more than 500,000 Delicious users and 2 million shared bookmarks, the solution produced a set of trustworthy users. No spammers were found in the top 200 recommendations. While there are obvious uses for SPEAR in shopping and friend recommendation engines, says Noll, “The SPEAR algorithm itself is not restricted to the online world. We imagine to use SPEAR, for example, for estimating the expertise of researchers by analyzing scientific publications. Such publications – whether available as online versions or printed out on paper – provide all the information we need.” Expertise may have an algorithm across all industries. Be first and be fascinating. For more information on SPEAR visit Michael G. Noll’s site.last_img read more
