Clarity on Jacob Zuma’s wives

first_img7 January 2010South African President Jacob Zuma, who practises polygamy in keeping with traditional African culture, has not five but three wives, any of whom may accompany him on official engagements.In a statement aimed at correcting media reports following Zuma’s wedding to Tobeka Madiba-Zuma on the weekend, the Presidency said that South Africa’s Constitution and public service regulations did not make provision for a First Lady or First Ladies, and that there was thus “no such official designation”.Contrary to media reports, Zuma has not five but three wives: Sizakele Khumalo, Nompumelelo Ntuli, and Tobeka Madiba. He also has a fiancee, Bongi Ngema.When it comes to official or public engagements, the Presidency said, it is up to Zuma to decide whether he is accompanied by any or all of his wives. “This is his prerogative, and has been the practice since he took office.”The Presidency said it provided “administrative support” to the President’s wives through its spousal office, “as has been the practice in past administrations”.While Zuma’s wives might take part in community work or other activities that supported the President’s work, this was purely voluntary, as they were not part of the Presidency or the public service.MaKhumalo (in isiZulu culture, married or adult women have the prefix “Ma” added to their surnames), whose area of interest is agriculture and food security, runs a vegetable garden project in Zuma’s home village of Nkandla in KwaZulu-Natal.KaMadiba (the prefix “Ka” is used for names already beginning with “Ma”) is interested in health care, especially work relating to the fight against cervical cancer. MaNtuli’s focus is on social development; she works to help orphans and vulnerable children.SAinfo reporterWould you like to use this article in your publication or on your website?

What’s Next For Taming Big Data?

first_imgReadWrite Sponsors 3 Areas of Your Business that Need Tech Now Tags:#Big Data#enterprise#NoSQL#Taming Big Data#Virtualization Cognitive Automation is the Immediate Future of… Imagine you are walking in London and want to book a trip to New York at the last minute: You hop online to search for a hotel. The smartphone you are holding helps you find an establishment that looks appealing. You tap a few buttons to send your credit card information.Unbeknownst to you, however, there is only one available room left at this hotel for the night you need. You and and another traveler, from Brazil perhaps, are vying for the same space. That person is trying to make the reservation from a laptop at his office.Could these two transactions be handled at the exact same time?Can the hotel see a consistent view of this globally distributed data?Could the transactions be handled in a way that the hotel owner can identify where each request originated from?Could the hotel distinguish on which device the purchase was made and any other personal information required?If the two transactions were being handled by a traditional SQL database with a siloed network configuration and little ability to scale on demand or access data in real time, the short answer would be, “No.”As Jerry Chen, VP of VMware’s Cloud and Application Services noted recently: “The monolithic database of the past cannot meet the needs of modern applications.” What is needed, he added, are designs that support high-availability low-latency applications.The Influence Of Big DataYour experience with booking a room is a perfect example of how large amounts of important, fast-moving information – commonly known as Big Data – is creating problems and opportunities for customers and the companies that serve them.While modern technologies provide faster access to higher volumes of both structured and unstructured information at any time of the day, making sense of the bits and pieces of unrelated data has required a radical shift in the way we organize networks and the Internet. It’s a challenge for even seasoned IT developers and database deployers.In addition, real-world events such as the Arab Spring and the earthquake and tsunami in Japan have challenged engineers and developers to break through existing constraints and work wonders in hyperconnectivity using non-traditional methods.Historically, companies sorted customer and transactional data in neat rows and columns of databases. These databases were built and managed by Structured Query Language (SQL) and stored in isolated, or siloed, networks.But traditional, hard-disk-drive-based database products forged on SQL can no longer handle the deluge of Big Data in a timely fashion. The era of Big Data calls for new strategies and new approaches to queries.The limitations of traditional SQL-based databases have prompted a slew of innovative developments in this direction starting with NoSQL distributed database models. These types of software platforms have caught the eye of decision-makers in the financial services, e-commerce, government and R&D communities.NoSQL has the capacity to answer to their need to process Big Data sets as they happen. However, many NoSQL deployments still fail to cope with scenarios like the one detailed above because they cannot provide consistent speed or scale. Additionally, many NoSQL offerings lack maturity when dealing with data that needs to span multiple datacenters across vast distances.Other Innovations Add SupportTo keep up with the true volume and velocity of information from multiple sources, innovations in cloud computing are being paired with high-performance “in-memory” storage on database appliances created to address the obstacles of managing Big Data.While cloud-based systems have helped develop online computing and software service delivery systems, IT developers and database deployers have adopted the cloud to take advantage of the ability to scale to globally distributed marketplace. Meanwhile, the addition of solid-state memory drives to storage devices has given companies an extra layer of quickly accessible data. These configurations allow for more rapid database queries and transactions – and thus the ability to deal with much larger data sets in real time.But the raw technology is only part of the equation. No matter how powerful the exterior influences, IT developers and database deployers will always need tool sets that help them to design for their current Big Data database needs (such as our hotel booking example) as well as prepare for a future where Big Data needs to be addressed at multiple levels.The tools must be customizable and easy to use – no matter the developer’s existing training. These offerings must also be easy to manage and easy to connect with new technology trends.VMware’s GemFire and SQLFire software are designed to address just those needs of developers and deployers.GemFire is a database software product that allows for data distribution, data replication, caching and data management at the exact moment the information is needed.SQLFire is a distributed data management platform which functions and performs much like GemFire, but has a user interface and programming framework familiar to developers who are more comfortable programming in SQL interface and tools.Both GemFire and SQLFire help companies move beyond concerns with speed and scale and tackle Big Data applications head on.Image courtesy of Shutterstock.center_img Related Posts IT + Project Management: A Love Affair Massive Non-Desk Workforce is an Opportunity fo…last_img read more

Dehydration

first_imgDefinitionDehydration occurs when your body does not have as much water and fluids as it should.Dehydration can be mild, moderate, or severe, based on how much of your bodys fluid is lost or not replaced. Severe dehydration is a life-threatening emergency.CausesYou can become dehydrated if you lose too much fluid, dont drink enough water or fluids, or both.Your body may lose a lot of fluid from:Sweating too much, for example, from exercising in hot weatherFeverVomiting or diarrheaUrinating too much (uncontrolled diabetes or some medications, like diuretics, can cause you to urinate a lot)You might not drink enough fluids because:You dont feel like eating or drinking because you are sickYou are nauseatedYou have a sore throat or mouth soresOlder adults and people with certain diseases, such as diabetes, are also at higher risk for dehydration.SymptomsSigns of mild to moderate dehydration:ThirstDry or sticky mouthNot urinating muchDarker yellow urineDry, cool skinHeadacheMuscle crampsSigns of severe dehydration:Not urinating, or very dark yellow or amber-colored urineDry, shriveled skinIrritability or confusionDizziness or lightheadednessRapid heartbeatBreathing rapidlySunken eyesListlessnessShock (lack of blood flow through the body)Unconsciousness or deliriumExams and TestsYour health care provider will look for these signs of dehydration:Low blood pressureBlood pressure that drops when you stand up after lying downWhite finger tips that dont return to a pink color after your doctor presses the fingertipSkin that is not as elastic as normal. When your health care provider pinches it into a fold, it may slowly sag back into place. Normally, skin springs back right away.Rapid heart rateYour doctor may do lab tests:advertisementBlood tests to check kidney functionUrine tests to see what may be causing dehydrationOther tests to see what may be causing dehydration (blood sugar test for diabetes)TreatmentTo treat dehydration:Try sipping water or sucking on ice cubes.Try drinking water or sports drinks that contain electrolytes.Do not take salt tablets. They can cause a serious complication.Learn what to eat if you have diarrhea.For more severe dehydration or heat emergency, you may need to stay in a hospital and receive fluid through a vein (IV). Your health care provider will also treat the cause of the dehydration.Dehydration caused by a stomach virus should get better on its own after a few days.Outlook (Prognosis)If you notice signs of dehydration and treat it quickly, you should recover completely.Possible ComplicationsIf untreated, severe dehydration may cause:DeathPermanent brain damageSeizuresWhen to Contact a Medical ProfessionalYou should call 911 if:The person loses consciousness at any time.There is any other change in the persons alertness (for example, confusion or seizures).The person has a fever over 102 F.You notice symptoms of heatstroke (like rapid pulse or rapid breathing).The persons condition does not improve or gets worse despite treatment.PreventionDrink plenty of fluids every day, even when you are well. Drink more when the weather is hot or you are exercising.If anyone in your family is ill, pay attention to how much they are able to drink. Pay close attention to children and older adults.Anyone with a fever, vomiting, or diarrhea should drink plenty of fluids. DO NOT wait for signs of dehydration.If you think you or someone in your family may become dehydrated, call your health care provider. Do this before the person becomes dehydrated.ReferencesChen L.
