    Recent corporate s, such as EBS International and Société Générale, have brought about renewed scrutiny into corporate governance mechanisms. Given the pervasiveness of Information Technology (IT) in many organizations, the examination of corporate governance mechanisms also includes IT governance mechanisms. IT governance is defined as “a structure of relationships and processes to direct and control the enterprise in order to achieve the enterprise’s goals by adding value while balancing risk versus return over IT and its processes”.
    In light of increased public awareness, professional bodies such as the Information Systems Audit and Control Association (ISACA) have undertaken a number of steps to provide guidance in the implementation of effective IT governance. The approach taken by ISACA appears to be largely based upon two concepts. The first concept relates to increasing the awareness of issues and concepts relating to IT governance in the public domain. The second concept involves the provision of guidelines and the identification of best-practice IT governance mechanisms. Interestingly, the effectiveness of these best-practice mechanisms in improving IT governance is largely based upon conceptual arguments. As such, it becomes important to ascertain if these best-practice mechanisms do impact upon the level of IT governance.
    As IT escalates in terms of importance and pervasiveness in the operations of firms, it is inexorably tied to specific mechanisms that are prescribed for good corporate governance, most notably, a sound system of internal controls. Accordingly, effective IT governance is a critical underpinning for a system of good corporate governance that minimizes agency losses for a firm.

Self-repairing software tackles malware

     University of Utah computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer
again.
     A3 is a software suite that works with a virtual machine - a virtual computer that emulates the operations of a computer without dedicated hardware. The A3 software is designed to watch over the virtual machines operating system and applications, says Eric Eide, University of Utah research assistant professor of computer science leading the university s A3 team with U computer science associate professor John Regehr. A3 is designed to protect servers or similar business-grade computers that run on the Linux operating system. It also has been demonstrated to protect military applications.
     The new software called A3, or Advanced Adaptive Applications, was co-developed by Massachusetts-based defense contractor, Raytheon BBN. The four-year project was completed in late September.
     There are no plans to adapt A3 for home computers or laptops, but Eide says this could be possible in the future.
     "A3 technologies could find their way into consumer products someday, which would help consumer devices protect themselves against fast-spreading malware or internal corruption of software components. But we havent tried those experiments yet," he says.
     Unlike a normal virus scanner on consumer PCs that compares a catalog of known viruses to something that has infected the computer, A3 can detect new, unknown viruses or malware automatically by sensing that something is occurring in the computer s operation that is not correct. It then can stop the virus, approximate a repair for the damaged software code, and then learn to never let that bug enter the machine gain.
     While the military has an interest in A3 to enhance cybersecurity for its mission-critical systems, A3 also potentially could be used in the consumer space, such as in web services like Amazon. If a virus or attack stops the service, A3 could repair it in minutes without having to take the servers down.

     It now seems to me that what matters most in the majority
of organizations is to have reasonably intelligent, hard-working
managers who have a sense of pride and loyalty toward their
organization; who can get to the root of a problem and are inclined
toward action; who are decent human beings with a natural empathy
and concern for people; who possess humor, humility, and common
sense; and who are able to couple drive with stick-to-it-iveness* and
patience in the accomplishment of a goal.
     It is the ability to make positive things happen that most
distinguishes the successful manager from the mediocre or
unsuccessful one. It is far better to have dependable managers who
can make the right things happen in a timely fashion than to have
brilliant, sophisticated, highly educated executives who are excellent
at planning and analyzing, but who are not so good at implementing.
The most cherished manager is the one who says “I can do it,” and
then does.
     Many business schools continue to focus almost exclusively
on the development of analytical skills. As a result, these schools are
continuing to graduate large numbers of students who know a great
deal about analyzing strategies, dissecting balance sheets, and using
computers — but who still don’t know how to manage!
     As a practical matter, of course, schools can go only so far
in teaching their students to manage. Only actual work experience
will fully develop the kinds of managerial traits, skills, and virtues
that I have discussed here.

3 Homemade Natural Cleaning Products

One of my earliest memories is of my mother cleaning with what looked to me like cooking ingredients. She would be listening to the radio as she poured baking soda, lemon, and vinegar combinations on the surfaces of our home. Magically these natural cleaning products kept our home clean and smelling fresh, without stretching an already thin household budget. Here are a few basic household ingredients and items you can use to clean your home.

Vinegar naturally cleans like an all-purpose cleaner. Mix a solution of 1 part water to 1 part vinegar in a new store bought spray bottle and you have a solution that will clean most areas of your home. Vinegar is a great natural cleaning product as well as a disinfectant and deodorizer. Always test on an inconspicuous area. It is safe to use on most surfaces and has the added bonus of being incredibly cheap. Improperly diluted vinegar is acidic and can eat away at tile grout. Never use vinegar on marble surfaces. Don"t worry about your home smelling like vinegar. The smell disappears when it dries.

Lemon juice is another natural substance that can be used to clean your home. Lemon juice can be used to dissolve soap scum and hard water deposits. Lemon is a great substance to clean and shine brass and copper. Lemon juice can be mixed with vinegar and or baking soda to make cleaning pastes. Cut a lemon in half and sprinkle baking soda on the cut section. Use the lemon to scrub dishes, surfaces, and stains.

Baking soda can be used to scrub surfaces in much the same way as commercial abrasive cleansers. Baking soda is great as a deodorizer. Place a box in the refrigerator and freezer to absorb odors. Put it anywhere you need deodorizing action. Try these three kitchen ingredients as natural cleaning products in your home.

Working for on demand startups like Uber and TaskRabbit is supposed to offer flexible hours and higher wages, but many workers have found the pay lower and the hours less flexible than they expected. Even more surprising: 8 percent of those chauffeuring passengers and 16 percent of those making deliveries said they lack personal autoinsurance.

Those are among the findings from a survey about the work life of independent contractors for on-demand startups, a booming sector of the tech industry, being released Wednesday.

"We want to shed light on the industry as a whole," said Isaac Madan, a Stanford master s candidate in bioinformatics who worked with two other Stanford students and a recent alumnus on the survey of 1,330 workers. "People need to understand how this space will change and evolve and help the economy."

On-demand, often called the sharing economy, refers to companies that let users summon workers via smartphone apps to handle all manner of services: rides, cleaning, chores, deliveries, car parking, waiting in lines. Almost uniformly, those workers are independent contractors rather than salaried employees.

That status is the main point of contention in a recent rash of lawsuits in which workers are filing for employee status. While the survey did not directly ask

contractors if they would prefer to be employees, it found that their top workplace desires were to have paid health insurance, retirement benefits and paid time off for holidays, vacation and sick days - all perks of full time workers. Respondents also expressed interest in having more chances for advancement, education sponsorship, disability insurance and human relations support. Because respondents were recruited rather than randomly selected, the survey does not claim to be representational but a conclusion one may come to is that flexibility ofnew jobs comes with a cost. Not all workers are prepared for that!
