Security Measure For Your Business | Westbound415

One aspect of operating computers in your businesses to make sure that the security measures are taken care of before problems occur. Those measures can include locking down the server and setting the permissions properly, but it may also be necessary for you to incorporate some type of encryption software by WinMagic into the mix. What can this do for your company to help ensure that any sensitive data that you are using on the computers is going to be protected?

One of the reasons why it is important to encrypt the data is because in most cases, people are going to be accessing the data from outside of the local network. This is especially the case if you tend to travel and are going to be logging into the server from your laptop. If you have the right type of laptop data security enabled as well as full disk encryption on your local computers, you will be able to login without having to worry about that data. It is also important for you to consider the transfer of the data and to keep people from intercepting it as it is being transferred.

Along with encrypting any data that is on the computers in your company location, it is also important to avoid other problems that can occur. These problems can include such things as viruses, spyware, and hackers. It is necessary for you to go incorporate the right type of software, which will block the efforts of those unscrupulous individuals and programs at accessing the data that is on your computer.

Unraveling intricate interactions, 1 molecule at a time

Monday, August 13, 2012

A team of researchers at Columbia Engineering, led by Applied Physics and Applied Mathematics Associate Professor Latha Venkataraman and in collaboration with Mark Hybertsen from the Center for Functional Nanomaterials at the U.S. Department of Energy's Brookhaven National Laboratory, has succeeded in performing the first quantitative characterization of van der Waals interactions at metal/organic interfaces at the single-molecule level.

In a study published online August 12 in the Advance Online Publication on Nature Materials's website , the team has shown the existence of two distinct binding regimes in gold-molecule-gold single-molecule junctions, using molecules containing nitrogen atoms at their extremities that are attracted to gold surfaces. While one binding mechanism is characterized by chemical interactions between the specific nitrogen and gold atoms, the other is dominated by van der Waals interactions between the molecule and the gold surface.

"A detailed understanding of van der Waals interactions is a key step towards design of organic electronic devices," says Sriharsha Aradhya, the study's lead author and a Ph.D. candidate working with Venkataraman. "Apart from the fundamental importance of these measurements, we are also excited about its applications. Understanding the effects of van der Waals interactions is tremendously important for creating and optimizing devices with organic building-blocks".

"Many proposals for future photovoltaic and flexible electronic devices are based on organic molecules because they are cost-effective," Venkataraman adds, "and scientists need to have a deeper understanding of these van der Waals interactions. Our work opens up the possibility of measuring and characterizing the strength of interaction between a variety of molecules and metallic surfaces a single-molecule at a time."

The forces of attraction between atoms and molecules come in different varieties and strengths, Aradhya explains. One of the most ubiquitous forms of attraction in nature is the van der Waals force. In contrast to specific interactions arising from bonding between atoms, van der Waals interactions represent non-specific interactions with subtler underpinnings. While originally intended to explain the apparent continuity between gaseous and liquid phases of matter, these forces have come to be recognized as an important aspect in answering such diverse questions as how does water boil inside a pressure cooker? How are geckos able to climb walls vertically? Or how can you control the organization of molecules for an organic LED smartphone display screen?

As devices like the latter become increasingly common, there has been a good deal of renewed interest in van der Waals interactions, known to lie at the heart of the structure and functionality in such devices. These interactions between organic molecules and metallic surfaces are central to a diverse range of phenomena such as catalysis of reactions, molecular electronic architectures, and molecular self-assembly in nature and engineered material. However, van der Waals interactions remain challenging to characterize directly at the fundamental, single-molecule level both in experiments and in theoretical calculations.

For this Columbia Engineering study, the researchers used their custom-built conducting atomic force microscope to make simultaneous measurements of force and conductance in single-molecule junctions. They combined their measurements with theoretical calculations and simulations, carried out in collaboration with Hybertsen at Brookhaven, in order to provide a unique quantitative measurement of the relative importance of specific and non-specific interactions at the single-molecule level, in a regime where both are comparable.

"In simple terms, conductance of the junction acts as a fingerprint of the structure," explains Aradhya. "At the same time, the measured force ? especially the force needed to rupture the junction ? can be used to deduce its mechanical properties."

While similar studies have been reported by a few research groups around the world, such precise studies have typically required the measurements to be carried out at very low temperatures and in high vacuum. Venkataraman's and Aradhya's experimental setup was optimized for very high sensitivities even at room temperature and ambient conditions. This allowed the team to perform thousands of individual single-molecule measurements, resulting in statistically robust results. The researchers then performed extensive density functional theory calculations to help them understand the mechanisms underlying their measurements.

"Taken together, this unique combination of our state-of-the-art experimental and theoretical efforts has resulted in this major progress in quantifying van der Waals interactions," Venkataraman says.

Future research, she adds, will include trying to control the interplay of van der Waals non-specific interactions with chemical modifications, in order to "achieve interesting functionality at the single-molecule level, which is an active area of research in our lab."

"We're very excited about this," she says, "as our efforts towards developing a reliable way to simultaneously measure force and conductance are yielding exciting new opportunities to relate structure, mechanics, and electronics at the single-molecule level."

As Hybertsen notes, "The development and validation of efficient theoretical models for the van der Waals interaction is still in its nascent stage. We expect that our work will also have an impact on this theoretical effort underway among many research groups around the globe to develop accurate treatment of van der Waals interactions."

The experiments were conceived by Aradhya and Venkataraman. The experimental tools and large dataset analysis techniques necessary for this study were developed by Aradhya, along with Michael Frei, a recent graduate of Venkataraman's lab. The modeling of the interactions and the calculations were conceived and executed by Hybertsen at Brookhaven.

Unified Communications Strategies Blog ? ?True? Unified Messaging ...

August 12, 2012

By Art Rosenberg, The Unified-View/ UC Strategies Expert

It?s really tough for any size organization to change the way it?s end users communicate with each other, as well as how increasingly automated business applications interact with those same end users. Not only are there now different ways to communicate, but, with BYOD mobility, the variety of mobile endpoint devices that end users can choose to utilize for both business and person-to-person contacts, requires greater flexibility in all call handling and messaging user interfaces.

Nowhere is this confusion more evident than in how business users will migrate their old ?telephone answering? needs to exploit the benefits of UC-enabled telephony capabilities such as presence management and ?click-to-call? connections integrated with all forms of online information and messages. It is not just the new UC capabilities that are of interest, but it?s the old voicemail shortcomings that we have put up with for so long that we can finally get rid of. However, the big challenge is how to migrate from old voicemail systems and culture to the new ways that phone calls can be initiated more efficiently, as well as the way failed call attempts will be dealt with.

In addition to cultural issues and end user education (training), the migration to UC-enabled messaging may require changes in how callers are handled, as well as how call recipients are notified about incoming calls and messages and respond to them. It may very well be that internal users can be trained to do things differently, but external callers will still be initiating phone calls the same way they have always done. Until presence federation is universally available to all end users and they have learned the better ways to initiate person-to-person contacts intelligently and contextually, person-to-person phone calls will remain a staple of business communications. It does take ?two to tango!?

So, What Was So Bad About Old Voicemail?

Actually, nothing terrible, but it just wasn?t very efficient for end users, especially outside callers.

For openers, in order to leave a voice message, outside callers had to initiate a conversational phone call attempt, wait for the ring count to run down, and then they could leave a voice message. Aside from any cost of the phone call, it was a waste of the outside caller?s time when all they wanted in the first place was to leave a message, not necessarily have a long conversation. Internal users, however could access mailboxes with no problem. Today, of course, we also have email and texting alternatives.

I remember deliberately making calls late at night as an outside caller, when I knew the call recipient was gone for the day, to leave a message without having a conversation. I thought it was funny when they didn?t bother changing their recorded message on their voice mailbox, which would usually say something like, ?I just stepped away from my desk?? Sure!

In some cases, outside callers could be given a ?backdoor? main number, which would then allow direct access to a recipient?s mailbox, but few organizations bothered to do that or even publicize such capabilities to outside callers.

There have been a number of new service functions that make things better for call recipients, e.g., options for screening incoming calls that are leaving voicemail messages, with the option to accept the calls immediately, if desired. More practical, however, is the option for the recipient to have voice messages transcribed to text, which can more be efficiently reviewed and managed than voice, and won?t require manual transcription of important items like numbers, names, etc. Even more features can be expected for call recipients, in terms of notifications and response options.

(It never helped that phone calls could not include information about the purpose of the call, like the subject line of a text message.)

Time to Do More For ?Callers?

However, we need to see more options showing up for ?callers,? who will now be using multi-modal smartphones and tablets, not just traditional voice/touchtone desktop phones. Now those ?callers? will also be increasingly sending a variety of messages, including voice messages, which can be created easier and faster than by typing text. By UC-enabling such messaging, senders will also have a more convenient and flexible form of initiating contacts that can also transition quickly and more efficiently into voice or video conversations when both parties so desire.

So, we should look forward to having voice messaging in the future, but not the old ?voicemail jail? of the past. Leading technology providers who specialize in voice messaging, such as AVST, are in an ideal position to help migrate legacy voice mail gracefully to the future of UC-enabled, true unified messaging (UM). Hybrid ?cloud? based implementations will also provide a convenient way to facilitate the shift from legacy CPE voicemail systems to support the new world of BYOD and Mobile UC.

This issue of what will happen to voicemail was also discussed at length in a previous post on this site.

Health and Fitness, Wellness and Nutrition, Diseases and Medicines ...

If you are a middle-aged man and you want to live a long time, all you
need is a good lifestyle - some good genes would also help. Make sure
you don't become obese, remember to exercise regularly, keep your blood
pressure down, avoid the boozy lifestyle and keep away from foods high
in refined sugars, say experts from the Pacific Health Research
Institute, Hawaii, USA.

You can read about this new study in the Journal of the American Medical Association (JAMA).

If you look after yourself in this way your chances of reaching 85, and being healthy at that age, are five times greater than for men who stray off the beaten track.

The researchers looked at data on 5,820 Japanese/American males - they had been monitored for four decades. The men were initially monitored in 1965 - at that time they had an average age of 54 and were all healthy.

They were followed up in 2005. The scientists found that the following, either in isolation, or in combination, significantly influenced whether the men lived a long life, and also whether their extra years were healthy ones:

-- obesity
-- alcohol consumption (3+ drinks a day is too much)
-- high blood sugar
-- hypertension (high blood pressure)
-- high level of triglycerides

All the factors listed here contributed towards a reduced lifespan and a higher chance of being unhealthy during old age.

They found that a man who had drunk a lot, was fat, had high blood pressure, smoked and had high levels of sugar and triglycerides in his blood would have a 78% chance of never living till the age of 85. His chances of reaching 90 were just 6%.

However, a man who had drunk either nothing or moderately, had not been overweight, exercised regularly, did not smoke, had normal blood pressure, normal blood sugar levels and normal levels of triglycerides, had a 69% chance of reaching 85 - and also being healthy at that age.

Dr. Bradley Willcox, study leader, was surprised at how starkly the different lifestyles influenced longevity and health. He said that smoking is the major factor here, closely followed by high blood sugar during middle age. The scientists also found that a middle-aged man's grip strength was closely linked to his lifespan - the stronger his grip, the longer he is likely to live. As grip strength is linked to physical fitness, middle-aged men should make sure they do regular physical exercise, they said.

Other factors influence how healthy men are likely to be when they are old - the higher the academic level of a man, the healthier he is likely to be when he is old. Married men live longer than single men, but do not enjoy better health during old age (perhaps they live longer because their wives help them remember to go to their doctors, get their medications, and take them. Also, spouses can become carers).

The study covered the mid sixties to the turn of the century, before many drugs came onto the market.

(AP) ? A year after a far-right militant's bomb and gun attacks exposed flaws in Norway's terror preparedness, police are being criticized for failing to improve their ability to stop a gunman bent on inflicting mass casualties.

In contrast to the 1999 Columbine High School massacre in Colorado, which led to sweeping changes in police tactics and training in the U.S., the massacre of 77 people in July last year hasn't had a tangible impact on Norway's police force, critics say.

"There are hardly been any visible changes from July 22 and until today. That is what our members tell me," said Arne Johannessen, who heads Norway's union for police officers. "Now things have to happen. Now both the leadership in the police and the politicians must take this seriously."

A government-appointed commission on Monday presented a long-awaited 500-page report outlining flaws ? and some bright spots ? in how police and other authorities responded to Norway's worst peacetime attacks.

The confessed gunman, right-wing extremist Anders Behring Breivik, set off a car bomb outside the government headquarters in Oslo, then drove to the Labor youth division's annual summer camp, disguised as a police officer, and opened fire. Eight people were killed in the explosion, while 69 people died in the massacre on Utoya island, in a lake some 25 miles (40 kilometers) from the capital.

Breivik's shooting massacre lasted for more than an hour before he surrendered to a police anti-terror unit. He is awaiting sentencing on Aug. 24.

Police had already admitted to a series of blunders, including flaws in communication systems and the breakdown of an overloaded boat carrying the anti-terror squad. Norway's only police helicopter was left unused, its crew on vacation.

But the report also questioned the actions of the first officers to arrive on the shore of the lake, saying they received instructions to get an overview of the situation and await the anti-terror unit instead of trying to cross over to Utoya to confront the gunman.

Police Commissioner Oeystein Maeland said police will "critically review" procedures for dealing with an active shooter but added that so far officers haven't received any additional training on such situations.

"One of the questions we will look into is whether the training of ordinary police is extensive and good enough," he said.

Even Breivik, 33, testified during his trial that he expected police to confront him on his way to Utoya or within 15 minutes after firing his first shots on the island.

As it turned out, Breivik drove unhindered to Utoya after setting off the bomb ? even though police had the license plate of his getaway car. On Utoya, he called police twice to announce he was ready to give himself up, then kept killing as no officers had arrived to arrest him.

In the U.S., the Columbine massacre changed the standard police procedure for dealing shooting rampages.

Two officers exchanged fire with one of the teenage gunmen just outside the school door, then stopped ? as they had been trained to do ? to wait for a specially trained elite police team. During the 45 minutes it took for the elite team to assemble and go in, the gunmen shot 10 of the 13 people they killed that day.

After the tragedy, police across the country developed "active-shooter" training, calling for the first responding officers to rush toward gunfire to stop the gunman instead of waiting for a SWAT team.

It is not fair to judge the Norwegian police based on their response to the Utoya massacre because they hadn't dealt with that kind of situation before, said Richard Fairburn, an experienced police trainer and contributor to PoliceOne.com, an online resource for law enforcement.

"Now I believe in the U.S. individual patrol officers would try to go in there and stop that killing," he said. "Today's officers are as well trained and equipped as the first generation of SWAT teams."

"And I think other countries are probably thinking the same way now," he said. "I think they're going to have to adopt the kind of training that we've done and adopt better equipment in terms of weapons and protective gear."

The commission said the Norwegian Police Security Service ? similar to Britain's MI5 ? "could have become aware" of Breivik's plans, but stopped short of saying it could have stopped him.

However, it said the car bomb "could have been prevented through effective implementation of already adopted security measures" at the government complex.

Breivik was able to park a van with a fertilizer bomb just outside the high-rise that houses the prime minister's office. Plans to close off the street in front of the government building were approved in 2010, but work on constructing physical barriers had not been completed and no temporary obstacles had been set up. A parking ban in the area was not strictly enforced.

The commission also called for a "robust police helicopter service" to be set up in the Oslo police district.

Norway has now leased an extra helicopter from Britain, but delays in hiring additional crew members mean it's still not always available.

"We're not at a point yet where we can say that we have a police helicopter available 24 hours a day, seven days a week, but we're almost there," said Justice Minister Grete Faremo.

Though Breivik has admitted the attacks, he rejected criminal guilt, saying his victims had betrayed their country by embracing a multicultural society.

Prosecutors have said there were doubts about his sanity and suggested Breivik be committed to compulsory psychiatric care instead of prison.

Heavy Fine For No Safe Work Procedures | Safety Concepts

By admin on August 11th, 2012




Where hazards exist in a workplace it is the responsibility of the business to have in place up-to-date safe work procedures. ?Failure to have a any risk assessment procedure or a work procedure in place has cost one Brisbane firm a $120,000 fine.

?The business appeared before the court on the 30th July because of the two serious accidents occurring within a 2 month period. The significant fine it received was handed out after one worker was crushed between a silo and crane and another caught an arm in a manufacturing machine.

The business entered a guilty plea at the Brisbane Industrial Magistrates Court to a breach of the Workplace health and Safety Act section 24, which is failure to make sure that the workplace is safe.?

When the worker was crushed between the crane and silo there was no risk assessment for the maintenance of the silo and no work procedure.

When the arm of the worker was crushed there were guards missing from the core blowing machine that should have be inserted when the machine was not being used. The workers arm was trapped between the moving parts when the core blowing machine restarted while he was cleaning the sensors.

?The Magistrate said at the hearing that the company had not identified the risks or managed the hazards that were related to the ?moving parts on the plant and moving crane.?

Managed Health Care Takes A FallChildren's Health and Fitness ...

From The Press Telegram?..

Budget-strapped California is aggressively moving its poorest residents to managed health care, whether they?re seniors, rural residents or people with disabilities.

So, when Gov. Jerry Brown proposed earlier this year to transfer the nearly 900,000 poor children in the Healthy Families insurance program into Medi-Cal, he saw it as another opportunity to reduce costs by expanding dental managed care.

But something happened between then and now ? and that was Sacramento County.

Sacramento?s poor-performing Medi-Cal dental managed care program foiled Brown?s plans, legislators say.

?That failure certainly has stopped the expansion of dental managed care,? said Assemblyman Richard Pan, a Sacramento Democrat who also is a pediatrician.

?Hopefully we as a state have learned from that failure, and not only on the dental side.

?Hopefully, we can apply those lessons on the medical side.?

Sacramento joins Los Angeles as the only two counties with Medi-Cal dental managed care.

Their lackluster performance getting poor children into dentists made legislative leaders balk at adding Healthy Families kids to Medi-Cal dental managed care.

Instead, Sen. President Pro Tem Darrell Steinberg of Sacramento and Assembly Speaker John P?rez of Los Angeles negotiated a deal to move Healthy Families kids into the more flexible ? and potentially more expensive ? ?fee-for-service? dental care model under Medi-

Cal, interrupting the state?s seemingly unstoppable march toward managed care.

?We want to ensure that the challenges in certain counties are addressed before we contemplate a major expansion? of Medi-Cal dental managed care, said John Vigna, P?rez?s press secretary.
