The influence of ice scour on benthic communities at three contrasting sites at Adelaide Island, Antarctica

first_imgIce scouring is a key structuring force acting on high latitude shallow benthic communities. Despite its importance, detailed studies of scoured communities are still rare. Here we report the ecological effects of 12 iceberg impacts, across three contrasting study sites, at Adelaide Island, West Antarctic Peninsula. Grounded icebergs were marked with GPS and the newly formed scours (at 10-17 m depth) were sampled within 20 days of formation. Comparisons between scoured and adjacent unscoured assemblages were made using measures of abundance, biomass, taxon richness and the relative abundance of secondary consumers. Ice scouring was catastrophic at all sites, despite differences in substratum type, exposure and background community. Compared with undisturbed areas, scour assemblages were 95% lower in mean macrofaunal abundance and 75.9% lower in species richness. There was no general trend across all sites of ice scouring selecting for secondary consumers. The echinoid Sterechinus neumayeri and bivalve mollusc Mysella charcoti were highly abundant in undisturbed areas and were the biggest contributors to the observed differences between scours and undisturbed areas.last_img read more

Hepatitis C infections almost tripled over past 5-years

first_imgBy Garth A. RoseAccording to the Center for Disease Control (CDC) in Atlanta, Georgia, over just five years, the number of reported new hepatitis C virus infections has nearly tripled, reaching a 15-year high, according to new preliminary surveillance data.Because hepatitis C has few symptoms, nearly half of people living with the virus don’t know they are infected and most new infections go undiagnosed. Further, limited surveillance resources have led to underreporting, meaning the annual number of hepatitis C virus cases reported to CDC (850 cases in 2010 and 2,436 cases in 2015) does not reflect the true scale of the epidemic. CDC estimates about 34,000 new hepatitis C infections actually occurred in the U.S. in 2015.The Center says Hepatitis C kills more Americans than any other infectious disease reported It. The recently released data indicate that nearly 20,000 Americans died from hepatitis C-related causes in 2015, The majority of deaths were people ages 55 and older.“By testing, curing, and preventing hepatitis C, we can protect generations of Americans from needless suffering and death,” said Dr. Jonathan Mermin, director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. “We must reach the hardest-hit communities with a range of prevention and treatment services that can diagnose people with hepatitis C and link them to treatment. This wide range of services can also prevent the misuse of prescription drugs and ultimately stop drug use –which can also prevent others from getting hepatitis C in the first place.”New hepatitis C virus infections are increasing most rapidly among young people, with the highest overall number of new infections among 20- to 29-year-olds. This is primarily a result of increasing injection drug use associated with America’s growing opioid epidemic.However, the majority (three-quarters) of the 3.5 million Americans already living with hepatitis C are people born from 1945 to 1965. The so-called Baby-boomers are six times more likely to be infected with hepatitis C than those in other age groups and are at much greater risk of death from the virus.Recent CDC studies also indicate hepatitis C virus infections are growing among women of childbearing age, putting the youngest generation of Americans at risk. Hepatitis C treatment not only cures the vast majority of people living with the virus but also prevents transmission to their partners and children.The CDC cautions comprehensive approaches are needed to combat the dual epidemics of opioid addiction and injection-related infectious diseases. The U.S. Department of Health and Human Services (HHS) has implemented five specific strategies to fight the opioid epidemic and save lives and reduce the impact of injection-related infectious diseases. These strategies are:improving access to treatment and recovery services;promoting the use of overdose-reversing drugs:strengthening our understanding of the opioid epidemic through better public health surveillance:providing support for cutting-edge research on pain and addiction: and advancing better practices for pain management.Comprehensive syringe service programs (SSPs) are one of many tools communities can use to prevent hepatitis and other injection-related infectious diseases. These programs also help link people to treatments to stop drug use, test for infectious diseases that can spread to others, and medical care.However, a recent CDC analyses indicate 80 percent of young people with hepatitis C live over 10 miles from an SSP. Another study finds only a few states have laws that support full access to both comprehensive SSPs and hepatitis C-related treatment and preventive services for people who inject drugs.While new medicines can now cure hepatitis C virus infections in as little as two to three months, many people in need of treatment are not able to get it. HHS recently released the National Viral Hepatitis Action Plan, 2017-2020 that sets goals for improving prevention, care, and treatment of viral hepatitis and puts the nation on a course toward eliminating new hepatitis infections. “Stopping hepatitis C will eliminate an enormous disease and economic burden for all Americans,” said Dr. John Ward, director of CDC’s Division of Viral Hepatitis. “We have a cure for this disease and the tools to prevent new infections. Now we need a substantial, focused, and concerted national effort to implement the National Viral Hepatitis Action Plan and make effective prevention tools and curative treatment available to Americans in needlast_img read more

Empowerment for South Africa’s women

The pass book, a demeaning requirement, was an identification document that black people were ordered to carry around with them at the time.The feisty group left bundles of petitions containing more than 100 000 signatures at the office doors of then-Prime Minister JG Strijdom, and stood silently for 30 minutes outside his office.En route the women sang a protest song that was composed especially for the occasion and aimed at Strijdom – “Wathint’ abafazi, wathint’ imbokodo!” (You strike a woman, you strike a rock).In 2006, a re-enactment of the march was staged for its 50th anniversary, with many of the veterans reprising their roles.Addressing the status of women in South AfricaThis year’s Women’s Month kicked off with the three-day National Women’s Conference of more than 800 women from across the country. The conference is taking place in Boksburg, east of Johannesburg, from 1 to 3 August.The conference creates a platform for engagement on key issues affecting the status of women in the country.Xingwana said the objective of the gathering is to discuss and resolve key policy considerations to be included in the Gender Equality Bill, which is being developed to increase women’s participation in all sectors of society.Deputy President Kgalema Motlanthe, said Xingwana, is expected to respond to key issues raised by women when he delivers the conference’s closing address.Another conference that centres on the economic empowerment of women, said Xingwana, will take place on 11 and 12 August at the International Conference Centre in Durban, KwaZulu-Natal.She said that the event will review progress and identify measures needed to advance women’s empowerment as a prerequisite for global economic competitiveness.Honouring the country’s heroinesThis year, South Africa lost Albertina Sisulu, and Nonkumbi Bertha Gxowa died in November 2010. Both stalwarts were part of the 20 000-strong group that protested outside the Union Buildings in 1956.Xingwana said: “We owe it to Mama Gxowa and Mama Sisulu, and many other fallen heroines of the struggle for gender equality and freedom, to make this Women’s Month programme a success.”On 18 August, said the deputy minister of Human Settlements, Zoliswa Kota-Fredericks, her ministry will hand over 55 of the 1 956 houses built in the town of Brandfort, Free State province, to commemorate the 1956 women’s march.Brandfort is where Winnie Madikizela-Mandela, the former wife of Nelson Mandela and a struggle veteran in her own right, was put under house arrest in 1977 by the apartheid government.The Department of Public Works will also run a programme encouraging indigenous building methods in Limpopo. These techniques were traditionally led by women.The departments of Trade and Industry, Correctional Services as well as Social Development, to mention but a few, also have a line-up of activities to celebrate Women’s Month.last_img read more

100 Job Openings in the Windows Azure Group and What They Say About Steve Ballmer’s Latest Move

first_imgalex williams Related Posts Massive Non-Desk Workforce is an Opportunity fo… IT + Project Management: A Love Affair 3 Areas of Your Business that Need Tech Nowcenter_img Tags:#Analysis#enterprise#news#NYT Steve Ballmer is not shy about switching out management of the Windows Azure group. First we saw Ray Ozzie leave Microsoft. He left after Windows Azure became part of Bob Muglia’s responsibilities. Now Muglia is no longer the executive Ballmer wants to run the Server & Tools Business (STB), the division that oversees Windows Azure. In turn, Muglia will also be leaving Microsoft after the transition to new leadership.Ballmer’s new choice to lead STB depends on who has the experience to manage what the group sees as its main goals for the year ahead and beyond. It’s a critical decision. Ballmer has made the point often that the cloud represent Microsoft’s future.A quick look at the jobs Microsoft has open in the STB group gives insight into what that future may look like. STB is arguably the fastest growing part of the company. In the past week alone, there have been about 100 new job listings for positions in the division. Muglia’s position is not listed there but you can see what kind of roles are being developed and the skill sets required to do the work. Matching those job descriptions to the direction of the group and you can start to see some patterns.In particular, you see the leadership established by Muglia and Ozzie. Ozzie set the vision for Windows Azure and in many respect, Muglia served as its general, executing on the strategy.Under their successful leadership, Azure has moved from a cloud platform to one that seeks to extend into the all devices, embedded in every aspect of our lives. It’s an approach that means Windows 7 and Windows Phone 7 devices will have a future tied to the cloud. Mobile proliferation, smart operating systems and distributed networks are trends that will last at least a decade. You can see the influence of these movements in multiple ways on the Windows Azure group.Most of the positions we see on the Microsoft job search site are in software engineering. The team is also in need for people to do Web development, program management, consulting, operations, IT, marketing, research and sales. There are a few, though, that tell a larger story about Windows Azure future direction.For example, a marketing management position gives deeper insights into how these trends play into the Azure strategy and what the new leader will need to do in order to succeed. The description is testament to the influence the Windows Azure leadership has had on the group’s direction. The description refers to a post by Ray Ozzie about the paradigm of continuous services and connected devices. If you will recall, we wrote last week about a Flickr app on Windows 7 and Windows Phone 7 that synchronizes, in particular for a smartphone or tablet device. We are told this will be an ongoing story for Microsoft in the year ahead.Here’s the lead to a description for the marketing manager position:Do you want to join one of the fastest growing and energized groups at Microsoft? Are you interested in Microsoft’s strategy for expanding Windows and the Cloud to Specialized Devices? These Specialized Devices range from in-car infotainment systems, Digital Signage, Enterprise Handheld, Point of Service, Thin Clients, Industrial Controllers, Server Appliances, Connected TV and more. The Windows Embedded Business is impacting a number of industry and vertical segments including Automotive, Retail, Medical, Industrial Automation, Energy, Safety and Surveillance, and Consumer Electronics. The devices and scenarios our product and service enable are at the forefront Ray Ozzie’s “Continuous services / Connected Devices” paradigm (see http://ozzie.net/docs/dawn-of-a-new-day for more).From this we see a strategy that is moving off the PC and to the device. It plays into the need to develop services for the automobile, industrial equipment, consumer electronics and other devices.R “Ray” Wang, principal analyst and CEO of the Constellation Group, said that Muglia has been instrumental in building out the Azure group. His absence will be greatly missed.“Bob was instrumental in Microsoft building out its cloud strategy,” Wang said in an interview today. “A lot of the stuff he was doing on Azure was foundational to Microsoft’s future.”From our perspective, this seems more like a cultural shift. The world of connected devices and synchronized continuous services may be better lead by someone who has had a deeper role in developing a new generation of technologies more suited to a distributed world than the one where the PC was the once and only king. Cognitive Automation is the Immediate Future of…last_img read more
