first_imgEureka >> In what turned out to be a physical, back-and-forth contest, it was the Eureka Loggers that ended the night with hands raised in victory.Senior wide receiver Jaboc Lyons ran for 149 yards and three touchdowns and senior running back Sergio Manzo ran for 169 yards and a touchdown to lead a Loggers rushing attack that proved to be the difference down the stretch.“I just came out here and played my heart out for my team,” said Lyons, who had touchdown runs of 61, 33 and 50 yards in the …last_img

Findings vs Surmisings in Astronomy

first_imgThe Galex satellite (Galaxy Evolution Explorer) found “bright features” with an ultraviolet glow in the outskirts of a spiral galaxy, reported the BBC News.  What are they?  Scientists “think” they are large clusters of stars.  How much is known, and how much is interpreted?    The region imaged is the dark area around spiral galaxy M83 in the constellation Hydra.  Symmetrical arms of glowing hydrogen appear in the periphery of the more familiar central spiral.  If these are starry regions, the discovery is surprising: “The finding has surprised astronomers because the galactic periphery was assumed to lack high concentrations of ingredients needed to form stars.”  Each pixel in the Galex image would have to contain hundreds of thousands of stars.  It is impossible, therefore, for Galex to actually resolve them.  The Galex researchers compared their image with radio telescope data from the Very Large Array in New Mexico.  Did the VLA find the elusive stars?Light emitted in the radio portion of the electromagnetic spectrum can be used to locate gaseous hydrogen atoms.  These are seen as a good sign that the molecular form of the gas is also present.  And it is from this molecular gas that stars are born.    When the astronomers combined the radio and the Galex data, they found that they matched up.    “Clearly, the basic ingredients for star formation are out in those regions,” said Dr [Mark] Seibert [Carnegie Observatories].The radio telescope did not resolve stars, either.  The leap from glowing gas to large clusters of stars was bridged by theory.  From there, another leap into cosmology was made, but this time it was labeled a speculation:The astronomers speculate that the young stars seen in far-flung regions of M83 could have formed under conditions resembling those of the early Universe, a time when space was not yet enriched with dust and heavier elements.    But this process is not well understood.Despite the disclaimer, the above paragraph still claimed the stars were “seen” when, in actuality, the radio and UV instruments merely showed the presence of atomic hydrogen gas, from which they assumed molecular gas was present, from which they assumed stars would form, even though regions of this low density were not expected to have stars.    The Galex satellite is operated by JPL and Caltech.  The original press release is on the Galex home page.Maybe there are stars there.  These astronomers did little to ground their interpretations in empirical data.  Not a single star was observed in this gas, yet we are supposed to believe there are hundreds of thousands of them in each pixel?  Are we supposed to respect a pure speculation about the early universe resting on the admission that “this process is not well understood”?  Try that with gnome theory.  “We did not find any gnomes, but we think we found some gas they emit.  We didn’t expect to find that gas in the desert.  It might shed light, however, on how gnomes arose on the early earth, before the land was enriched with toadstools.”    If a scientist is not sure of something, let him say so or keep his speculations to himself.  Today’s scientists often do a very poor job of discriminating between observation and interpretation.  News reporters shift between them seamlessly and shamelessly.  It is up to the reader, and to sites like this, to sift the shift and lift the fogma.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Recounting the year past

first_imgMr Kingsley Makhubela : CEO of Brand South AfricaThe South African nation brand’s dynamism and resilience has withstood a challenging year and has remained strong.This is attested by South Africa’s performance in the World Economic Forum’s 2015 Global Competitiveness Index which placed the country within the top 50 most competitive nations in the world and the second most competitive on the continent.To summarise, South Africa’s biggest improvements come in the areas of: health and primary education (up 6 places), labour market efficiency (up 6 places), technological readiness (up 16 places), and innovation (up 5 places).  South Africa has also improved in the areas of: macro-economic environment (up 4 places), higher education and training (up 3 places), and business sophistication (up 2 places) while dropping in the area of infrastructure (down 8 places), institutions (down 2 places), goods market efficiency (down 6 places), financial market development (down 5 places) and market size (down 4 places).The Mo Ibrahim Index on African Governance saw South Africa holding steady at number 4 of 54 countries on the continent.  This Index looks at the performance of African countries in the areas of: safety and rule of Law, participation and human rights, sustainable economic opportunity and human development.  South Africa’s performance in each of these areas earns it the position of 7 in terms of safety and rule of law (up from position 8 in 2014), 4 in terms of participation and human rights, 2 in terms of sustainable economic opportunity and 6 in terms of human development, in Africa.The Brand Finance list of the 100 most valuable nation brands was also released in October this year.  According to this list, South Africa is the 37th most valuable nation brand in the world with a nett nation brand value of US$ 225 billion.  Brand Finance measures the strength and value of the nation brands of 100 leading countries using a method based on the royalty relief mechanism employed to value the world’s largest companies.  The study measures a nation brand across the following pillars: goods & services, investment and society. These are divided into sub-pillars: tourism, market, governance and people & skills.What do these numbers tell us about South Africa as a nation brand?These figures tell us that South Africa is a visible nation brand amongst the global community of nations.  This is something that all South Africans can be proud of since we remain a relatively young democracy.Our performance in these indices equally tell us that work needs to be done to ensure that we address the challenges that impact negatively on the nation brand and our global competitiveness.  This includes, amongst others, areas of education, healthcare, policy cohesion.  However, we can again feel confident that the National Development Plan has also highlighted similar areas and work is underway to decisively deal with these challenges.  Addressing these challenges systemically will see South Africa increase its global competitiveness.The numbers equally tell us that South Africa’s dynamism, energy, industriousness and personality encapsulated by the national pay-off line, Inspiring New Ways – continues to contribute to our nation brand equity.Domestic and international challenges aside, South Africa has all the ingredients to move ahead as a globally competitive nation.  This will however require the concerted effort of each citizen in our country since ultimately, the nation brand reflects each of us.The South African people are at the heart of this democracy. It is the people of this country who make our country great and it is the people of our country who show the world who South Africa is.  Brand South Africa thanks you for playing your part and carrying the South African brand with pride.Follow Mr Makhubela on @klmmakhubela  Mr Kingsley Makhubela Brand South Africa: CEOlast_img read more

Lightbeam from Mozilla shines light on online tracking

first_img Firefox has Click-to-Play cure for plugin plague More information: www.mozilla.org/en-US/lightbeam/ Explore further Citation: Lightbeam from Mozilla shines light on online tracking (2013, October 26) retrieved 18 August 2019 from https://phys.org/news/2013-10-lightbeam-mozilla-online-tracking.html Mozilla is now announcing a way to see who is watching you with its release of an add-on called Lightbeam. This is a Firefox add-on that will help Firefox users to both see and understand who is behind the data-tracking curtain. Announced Friday by Mozilla, the software community behind the Firefox browser, the plug-in is to show how one’s Internet browsing is being monitored. You can stop Lightbeam at any time by disabling it or uninstalling the add-on. Your Lightbeam data can be easily saved or deleted. Mozilla’s team points out that the “bad” in tracking lies in our lack of awareness of who is tracking and why. “Not all tracking is bad. Many services rely on user data to provide relevant content and enhance your online experience. But tracking can happen without the user’s knowledge,” according to Mozilla. “It should be you who decides when, how and if you want your browsing data to be shared. We recognize the importance of transparency and our mission is all about empowering users—both with tools and information.”Once the curtain is lifted, the Mozilla idea is that the user can make better, informed decisions about protecting privacy. Lightbeam reveals the parts of tracking that are not transparent to the average user. Viewers get to see third-party sites that one interacts with on the Web. Lightbeam shows relationships between these third parties and the sites you visit, relationships which one may not have been aware.Lightbeam comes to users via a download produced by Mozilla. The browser extension can create a real-time graph of all of the tracking cookies being deposited on your browser in your daily travels across sites. The add-on has three graphic representations, Graph, Clock and List. The Graph view is a visualization of every site you visit and third-party requests made from your browser. The Clock view shows connections over a 24-hour period. The List view has options for zooming in.Meantime, Mozilla is asking users’ help so that they can learn something too. Users can contribute their data to Mozilla’s Lightbeam database, a central open database showing how first- and third-party sites are connected to each other. Mozilla said, “Data from Lightbeam can help us and others to understand third party relationships on the web and promote further research in the field of online tracking and privacy.”The user also has the opportunity to disable crowdsourcing, however. The user can turn it off at any time. Lightbeam has its own “Privacy Notice,” in which Mozilla says, ” If you choose to send Lightbeam data to Mozilla (that’s us), our privacy policy describes how we handle that data.” The code for Lightbeam has been posted to Github. Lightbeam was funded by a grant from the Ford Foundation and the Natural Sciences and Engineering Research Council. Lightbeam was also helped by students at the Emily Carr University of Art and Design, in implementing visualizations for the add-on.last_img read more
