Ocean acidification and calcium carbonate saturation states in the coastal zone of the West Antarctic Peninsula

first_imgThe polar oceans are particularly vulnerable to ocean acidification; the lowering of seawater pH and carbonate mineral saturation states due to uptake of atmospheric carbon dioxide (CO2). High spatial variability in surface water pH and saturation states (Ω) for two biologically-important calcium carbonate minerals calcite and aragonite was observed in Ryder Bay, in the coastal sea-ice zone of the West Antarctic Peninsula. Glacial meltwater and melting sea ice stratified the water column and facilitated the development of large phytoplankton blooms and subsequent strong uptake of atmospheric CO2 of up to 55 mmol m-2 day-1 during austral summer. Concurrent high pH (8.48) and calcium carbonate mineral supersaturation (Ωaragonite ~3.1) occurred in the meltwater-influenced surface ocean. Biologically-induced increases in calcium carbonate mineral saturation states counteracted any effects of carbonate ion dilution. Accumulation of CO2 through remineralisation of additional organic matter from productive coastal waters lowered the pH (7.84) and caused deep-water corrosivity (Ωaragonite ~0.9) in regions impacted by Circumpolar Deep Water. Episodic mixing events enabled CO2-rich subsurface water to become entrained into the surface and eroded seasonal stratification to lower surface water pH (8.21) and saturation states (Ωaragonite ~1.8) relative to all surface waters across Ryder Bay. Uptake of atmospheric CO2 of 28 mmol m-2 day-1 in regions of vertical mixing may enhance the susceptibility of the surface layer to future ocean acidification in dynamic coastal environments. Spatially-resolved studies are essential to elucidate the natural variability in carbonate chemistry in order to better understand and predict carbon cycling and the response of marine organisms to future ocean acidification in the Antarctic coastal zone.last_img read more

If my credit union goes to the cloud will I need a CIO/CTO?

first_imgIn most credit unions – they rely on their CTO/CIO’s to make sure they spend their money wisely, align their technology with strategy, and translate IT speak between executives and the board.   In a perfect world, just like most business executives know some marketing, finance, business law, and operations they would be conversant in technology.    The more that occurs the more the organization can align strategy quicker and move faster.   It is widely believed that cloud will make your credit union more scalable, dynamic and flexible.  So it begs the question – as the Credit Union moves to cloud will there still be a need for our CIO/CTO?Ultimately, the short answer is not any time soon.There are four main reasons why Credit Unions need a CIO/CTO:Language – Let’s face Credit Unions have their own unique language.  We call customers members and our boards are volunteers.   Combine that with a share draft accounts and remote deposit capture and it isn’t like we can take any industries CIO/CTO and plop them down in a credit union without a learning curve.Technology Complexity – Credit Unions employ a very complex array of technology often dwarfing some business much larger.  We regularly say that credit unions efficiency requirements and processes require almost one server for every two to three employees.  Because of the niche nature of the industry – there are often only a handful of providers for each type of application.  Consequently – the ability to standardize on one approach, technology etc. is very difficult in the industry.   I once mapped the number of places an ATM transaction can go astray – it involved multiple systems, databases, VPNs etc. and was impossible to explain to a consumer.Technology Evolution – At the same time, technology is rapidly evolving.  Transactions and data flow between multiple services, delivery channels, and people.  Each time it moves or integrates it requires a unique set of knowledge and expertise.  While marketing and accounting has certainly changed over time – there aren’t new terms and approaches being coined daily…Security and Regulation – On top of all of that- the industry has a unique regulator that uses its own processes and approaches to IT security regulation and requirements.  Normal IT Security is tough but when you add it in the wide array of enterprise security requirements that we all face – it requires another set of skills different than most executives.As Credit Unions move to the cloud – none of these four factors changes.   Our terminology is the same, our complexity grows, technology evolves quicker and our security requirements are under constant evolution.  Put it all together and our Credit Union CIO/CTO’s are here to stay. 64SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Kirk Drake Kirk Drake is founder and CEO of Ongoing Operations, LLC, a rapidly growing CUSO that provides complete business continuity and technology solutions.

Tyson-Thomas, Syracuse look to continue strong start against Wagner

first_img Published on December 3, 2012 at 10:11 pm Contact David: [email protected] | @DBWilson2 Carmen Tyson-Thomas is still adjusting to her role.It doesn’t matter that she’s come off the bench in two of her three seasons at Syracuse. It still takes some getting used to.“It’s kind of tough with the expectation,” Tyson-Thomas said. “I would like to be starting. To embrace it is a bigger step; it’s a bigger role, so I guess outside of it all I’m adjusting. It’s been two years now, so I’m still adjusting.”First instinct would have pegged Tyson-Thomas as a starter for the 2012-13 season. The guard started 29 of 37 games last season and was one of just three Orange players to average double-digit scoring and play more than 30 minutes per game. But with the arrival of the best freshman class in SU history, the senior headed back to the bench as three rookies entered the starting lineup.Still, Tyson-Thomas has been invaluable during Syracuse’s start to the season. Tyson-Thomas looks to keep the Orange’s (7-1) strong start going as SU faces Wagner (2-4) on Tuesday at 7 p.m. in the Carrier Dome.AdvertisementThis is placeholder textDespite coming off the bench, Tyson-Thomas ranks second on the team with 11.9 points per game and third with 5.3 rebounds per game.“Carmen could easily be a starter, without a doubt,” Syracuse center Kayla Alexander said. “She’s a talented player. She can knock down shots. … She is very athletic, she can shoot the outside shot, she can get in there and do a pull up jumper, she attacks, so she can do a lot for our team.”Tyson-Thomas’ ability to do it all was on full display during the Orange’s 80-39 victory over St. Joseph’s. Alexander called it “the Carmen show” as the guard dominated all facets of the game.Tyson-Thomas led all scorers with 23 points on 7-of-12 shooting, including 3-of-5 from beyond the arc. The guard also got it done on the boards, hauling in a game-high 11 rebounds.“She killed it that game,” Alexander said. “She was incredible.”It’s performances like that one that separate her from a typical bench player. She’s led the Orange in scoring twice this season and has been held to single digits just twice as well. Nights where she takes over a game — like she did against the Hawks — prove that she’s more than just a bench player for SU.“She’s obviously a great player that can obviously start, and has started,” Syracuse guard Elashier Hall said. “But it’s great that she’s embraced the role as sixth man.“I mean obviously she could win sixth-man award right now.”Alexander has been the Orange’s most valuable player so far in this young season, but head coach Quentin Hillsman points to Tyson-Thomas’ willingness to come off the bench as what could be the difference this season for SU.Tyson-Thomas was arguably Syracuse’s third-best player last year, after Alexander and Iasia Hemingway. Now she brings that complete skill set off the bench for a second unit that has dominated so far.“She’s a very important part of our puzzle and she can play almost four positions for us,” Hillsman said. “So her versatility allows her to come off the bench and play every position.”She’s still adjusting, but she’s becoming more and more comfortable with her bench role.Her 22.1 minutes per game rank fifth on the team — the equivalent of a starter. The second team that she plays with during practice often beats the first team. When that unit gets on the court, she said they “like to kick it up a notch” and wreak havoc.It may not be the starting role that she wants, but it’s an opportunity she’s relishing.“We’re a team and we win together, we lose together,” Alexander said. “So I feel like at the end of the day all we want to do is win, so all of us will take our roles and do what we have to do to get our Ws.” Comments Facebook Twitter Google+last_img read more

Let’s read between the lines and say what cannot be said

first_imgDear EditorLincoln Lewis’s letter carried on Sunday 25 February in the Stabroek News laments the Governments silence and stance on the matter of the EXXON contract and the public demand, including mine. I stepped back and, as always, rely for explanations from history, while taking a deeper look at all that is going on. I, too, am self employed, and bread and butter gets in the way of applying those hours of going over the evidence to evolve with what seems irrational from very rational people; in this case the APNU-AFC administration, as you indicated that, “Government may very well have justifiable reasons […]” you do understand that there are no freebees in real life in the world we live in over the past hundred years to put a bracket. Things don’t happen from altruism. So let’s read between the lines Lincoln, and say what the Government can’t say.Two things are going on here, a border dispute and Exxon. It is not by magic that so far a repeat of what happened with the first appearance of EXXON has not so far occurred, that Venezuela by force has not removed Exxon as they did before. I’ve been going over oil and conflict from the time Hitler invaded Russia to Iraq. Oil is not a commodity powerful nations play with. If a not-so-favourable contract enables us to be free of the dooku that Venezuela has placed on our backs, and has used time and time again to intimidate and to economically suffocate us, then so be it with me. We will benefit, and you know as well as I do that we have other important resources that can be tapped into, once the money is available.If my research is accurate, and I am certain it is — the evidence is glaring before us — should we step back and pay attention? We lost our manufacturing industry because of that border controversy, and the oil crisis of the 70s coupled with our choice in the Cold War politics. In the 80s, I took rice and sugar to trade with Venezuelan traders. One told me in a shop at Morawhanna, the stop before Kumaka, that the border dispute was the Government’s, and that they say “that Venezuela is beautiful without the Venezuelans”. That was before Chavez. They are still fighting ethnic colonisation, but this claim to our Essequibo, though ridiculously porous, is intoxicating political mythology in that country.Our responsibility may be to explain to our countrymen that we have the best that our country has to offer in leadership, and some hard choices stand before them and us; it’s not as simple as it seems.Sincerely,Barry Braithwaitelast_img read more

Takun J: B-Day Celebration Will Be “Different”

first_imgOne of Liberia’s most dependable and “all ears” Hip-Co artists, who has spent several years providing proof to his fans and nation that Hip-Co music could one day have a mark in the entertainment industry, celebrated another birthday on May 14, 2014.With great wishes and respect from LIB LIFE, we wish you a happy belated birthday!Due to celebrate a grand B-Day bash at club Dubai on May 24, 2014, Takun J celebrates his b-day with an exclusive, pay-to-enter house party, set up for sincere well-wishers, smiling faces and a room filled with gifts.“If it’s free, everyone will fill the place, and since there isn’t much space on 146 block, I’ve decided to charge a fee for those who really want to celebrate my birthday with me,” He stated duringthe renovation of 146.Also, Takun mentioned during the 12 ambassadors weekly Hip-Co Accountability Lab meeting that he wanted to do something special for his fans, despite it being his birthday.He also mentioned doing something different from what most of his fans are accustomed to seeing and hearing every Friday night during “146” open mic.“It’s going to be big, I’m going to have different people on the mic other than what everybody is used to,” he added.Furthermore, “146” block has become the second home for many Hip-Co artists who use the popular hangout spot as a means for stage practice, collaborations and for a good time.“146 is a good place to go and polish your skills and be able to do it around the real stars,” stated Black boy, another aspiring artist who dreams of one day featuring in Takun’s tracks.Meanwhile, artists and entertainers from all genres of music, class and style showed up at the birthday boy’s “146”, openly showing the love and respect that the whole country has for their “super-star” artist.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)last_img read more

Is Politics an Evolutionary Force?

first_img(Visited 24 times, 1 visits today)FacebookTwitterPinterestSave分享0 Penn State evolutionists see politics interacting with natural selection to direct human evolution.A PhysOrg headline states, “Politics can interact with evolution to shape human destiny.”  The gist of the argument by Penn State political scientist Pete Hatemi is explained in this paragraph:The researchers said that there is an interaction between political and cultural forces and evolutionary results. Genes can shape culture and political institutions, which in turn can shape biology and physiology, passing on certain traits to future generations. The environment’s influence on adaptation and how it changes biology is better known and often easier to observe, said Hatemi, but the way culture can affect gene expressions in future generations is often harder to show and may take longer to reveal itself.Although he didn’t equate politics with natural selection, it’s hard to see how an evolutionist could deny it; the human brain, society and politics are all manifestations of natural selection in their view.  Most people see politics involving mental choices by intelligent agents, not unguided processes of the environment.  Politics may affect future generations, to be sure, but that occurs by intelligent design (whether beneficent or malevolent).It may not take as long as Hatemi thinks for politics to affect future generations.  Interestingly, he cites 20th-century totalitarian governments as examples of generational forces:One more obvious way to see how culture affects natural selection is the effect that politically inspired atrocities—for example, Communist purges in China and USSR and the Nazi Holocaust—have on genetic diversity, according to the researchers, who released their findings in a recent issue of Advances in Political Psychology.Hatemi did not think to draw a connection between the atrocities and the Darwinian ideology that inspired the worst of them (e.g., 11/30/05).Evolutionists view every subject in nature as a nail for which their only tool, natural selection, is the hammer.  But if natural selection determined their own will to write this paper, then, well—they can’t nail anything but their own brains.  Trick or treat: they’ve just refuted their own theory.  The sight of brains and blood spilling out of a hole in the head is pretty scary for Halloween, for sure.last_img read more

Court victory for single dads

first_img28 November 2003An unmarried father has won joint custody and joint primary residency for his son in a landmark Johannesburg High Court ruling that has given unmarried fathers’ rights a big boost.The Star newspaper reports that the unnamed man – he cannot be named to protect the identity of his two-and-a-half year old child – took his case to court after his live-in lover suddenly left him in September 2002, taking their child with her.The couple had met and become engaged very quickly. Shortly thereafter, the woman had fallen pregnant and they had bought a house together. The man told The Star that everything had “seemed perfect”.However, when he arrived home from work on 18 September, he found that the woman had disappeared with his son, who was just over one year old at the time. A letter was left for the man, providing contact details for the woman’s lawyer and her father, as well as some of her reasons for leaving.Police couldn’t helpAccording to The Star, the man tried approaching the police, but there was nothing that they could do about it.The next day he was given contact details for an attorney who contacted the woman’s lawyer and arranged for him too see his son.The Star reports that a fortnight later an agreement was reached between the couple, with the aid of lawyers, that the man could see his son every Saturday between 8am and 5pm. No overnight visits were allowed. In addition, the man would have to pay maintenance and would not be allowed to know where the woman and the boy lived.There followed a period characterised by arguments and disagreements. The man says his son had to be forced away from him at the end of each visit. Feeling that his son was being neglected, he approached social services for help.Family advocateThe woman reacted by barring him from seeing his child. To this the man responded with an emergency application to the Johannesburg High Court, which put him in contact with the Family Advocate’s office, which has a huge say in such cases because judges in most cases tend to follow the Family Advocate’s advice.The Family Advocate’s office investigated the case, which involved checking up on all aspects of the child’s life.When the case went to court in November, Judge Chris de Jager recommended joint custody and full residency for the father. He also ruled that the couple should return to court for another ruling when the child turned six.Not only is the man’s victory good news fur unmarried fathers, it also bodes well for Hindu and Muslim husbands, whose marriages are not recognised by law.Judge Maree commented that the man’s victory forced the law “not to discriminate in favour of marriage”.southafrica.info reporterlast_img read more

Scientist soars after career change

first_imgMarié Botha believes she is impacting South Africa’s economy and tackling social issues with her career. (Images: Supplied)Marié Botha is one of just a handful South Africans who has met Buzz Aldrin, the second man on the moon. It was a meeting that might not have happened if she had not decided to change her career field when she was at university.In her first semester in her first year, Botha recalls, she made a life-changing decision to turn to science. Looking back years later, she is grateful that she is a professional in this industry, because she believes she is making a difference to South Africa’s growth and development.Botha, who grew up in Pretoria, is a researcher at the Council for Scientific and Industrial Research (CSIR), a leading scientific and technology research, development and implementation organisation in Africa. “The CSIR is committed to supporting innovation in South Africa to improve national competitiveness in the global economy,” it explains.She was studying business commerce at the University of Stellenbosch, which she enjoyed, Botha says, when she was bitten by the science bug. “During my first year the realisation dawned on me of how much more the science field could offer, and how you could develop your own personal interest to really impact on the South African economy and its society.”GETTING STARTEDIn 2006, Botha completed her Bachelor of Commerce honours in logistics management; she went on to receive her Masters of Science in the field in 2008. “I graduated in 2006, started work in 2007. I did my Masters in my first year of work,” she says.“I got this incredible opportunity to start my career at the CSIR, as well as further my studies. This I have to attribute to my parents, who took the time to expose me to the absolutely incredible organisation that the CSIR is.”Botha started her career at the organisation as a researcher in the field of operations research, logistics and quantitative methods. From there, she moved to supply chain management, lean manufacturing and the aerospace industry.The 32-year-old explains that the decision to change career fields also had to do with the science field being stimulating and unpredictable. “It also afforded me the opportunity to further my academic qualification and my career development on a continuous basis.”Botha got involved in managing the supplier development programme for the Aerospace Industry Support Initiative (AISI). The main focus of the initiative is enabling and co-ordinating industry to be integrated into global supply chains.She has authored numerous scientific papers and developed strategies for the aerospace and non-aerospace industries. In addition, Botha is a member of the International Astronautical Federation’s Workforce Development for Young Professionals Committee and the Royal Aeronautical Society. She also serves on the council for the Aeronautical Society of South Africa.As the manager of the aerospace and composites initiatives, Botha runs a small and highly effective team of what she calls “a dedicated technical and administrative staff with support from other functions within the CSIR”.“My main responsibilities are to manage the Department of Trade and Industry’s Aerospace Industry Support Initiative, as well as the Department of Science and Technology‘s composites initiatives,” she explains.“I am also the key account manager for CSIR aerospace, which requires me to co-ordinate the internal CSIR aerospace functions.” With this profile she liaises with local and international aerospace organisations and companies.“International colleagues are intrigued by our history, our journey and our people, and in my field of work, how we managed to achieve the technological excellence we have.”SOUTH AFRICA’S ACHIEVEMENTSBotha says the South African industry has a strong history based on excellence through products such as the Rooivalk helicopter, the Seeker unmanned aerial vehicle (UAV), and the SumbandilaSat.Work in the industry in South African currently ranges from research and development institutions and manufacturers that supply directly to Airbus’s A350 and A400M programmes, among others, to a large defence industry as well as a network of small medium and micro enterprises supplying these organisations.“The main benefit of the industry to address the societal needs of South Africa is assisting with safety and security. This is obtained through the obvious defence applications, but also through additional not-as-evident cases such as UAVs safeguarding our borders, or even assisting with [curbing] rhino poaching.“The aerospace sector also assists with food security through crop management by satellite remote sensing, utilising satellite data to monitor natural fires, and developing an early warning system to assist with preventing and fighting these fires.”Aerospace is a key element in the government’s industrialisation strategy, she explains. “As such, our work contributes to the Department of Trade and Industry’s Industrial Policy Action Plan. This focuses on key areas to boost the country’s industrialisation capacity and participating economic base.”And one job created in an advanced manufacturing industry creates multiple additional jobs, she adds. “In doing so, a major societal benefit to South Africans is indirectly addressed.”Marié Botha says it was such an honour to meet Buzz Aldrin, the second man on the moon.PERSONAL ACCOMPLISHMENTSBotha is a member of the Golden Key International Honour Society. In 2014, she received the Collaboration Award and in 2012, she was received the Outstanding Contribution by a Team Award. She also received the Promising Young Researcher Award in 2008.Golden Key is the world’s largest honour society, connecting high-achieving individuals globally. The society focuses on academic excellence, leadership development and community service.About her meeting with Aldrin, Botha says it was an incredible experience. “It was a humbling experience meeting and talking to such a science icon, discussing South Africa, and its impact and future growth. I now have the photo of a lifetime.”last_img read more
