The system Medicare developed to rate nursing home quality is of little help to finding a satisfactory place.

The biggest concern with robots going against human values is that human beings fail to do sufficient testing and they've produced a system that will break some kind of taboo ( ' , 禁忌 ).

As I was considering all this, a press release from a respected research firm crossed my desk, announcing that the five-star rating system that Medicare developed in 2008 to help families compare nursing home quality also has little relationship to how satisfied its residents or their family members are.

In other departments, a new student is assigned a faculty adviser based on some system of distribution of the  departments advising load.

With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.

When the system thinks it's being jammed, it'll notify you via -94- push alert ( ' , 推送警报).

They will, however, need to know what system they're looking for.

Then, he's going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup.

The team behind the article and video in question make no mention of the system, or whether or not it detected them.

The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn't even track those statistics.

That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what's to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?Jamming concerns are nothing new, and they're not unique to security systems.

So it isn't surprising that you'll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.

So come on, folks: get on board with ditching the outdated tip system.

SimpliSafe, winner of our Editor's Choice distinction, utilizes a special system that's capable of separating incidental RF interference from targeted jamming attacks.

SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment.

Other systems also seem confident on the subject of jamming.

One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether.

No system is impenetrable, and none can promise to eliminate the worst case completely.

No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.

It means that a thief likely wouldn't be able to Google how the system works, then figure out a way around it.

It is difficult to crack SimpliSafe as its system keeps changing.

It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system's event log.

Interfering with a wireless security system is similar to interfering with a conversation.

If they detect something wrong while the system is armed, they'll transmit a wireless alert signal to a base station that will then raise the alarm.

However, we also verified that SimpliSafe's anti-jamming system works.

However, he'll need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.

Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn't be a universal magic formula for cracking it.

Different measures should be taken to protect one's home from burglary in addition to the wireless security system.

But how probable is it that someone will successfully jam their way into your home and steal your stuff?Let's imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system.

At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries.

A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.

Muscle performance can also be affected by a phenomenon called "central fatigue", in which an imbalance in the body's chemical messengers prevents the central nervous system from directing muscle movements effectively.

My research focus is on what happens to our immune system as we age.

One educator named Dori Roberts decided to do something to change this system.

She noticed there was a real void in quality STEM education at all levels of the public educational system.

She told BuzzFeed News that her freshman chemistry class required her to use Connect, a system provided by McGraw hill where students can suBMIt homework, take exams and track their grades.

We want to reach parents who are not plugged into the system, said Zaharopol.

System institutions are operating very efficiently based on this analysis, raising the question of the value of pursuing a broad scale outsourcing initiative.

Morgan said those findings—which included data from the system's 13 community colleges, 27 technical colleges and six universities—were part of the decision not to move forward with Governor Bill Haslam's proposal to privatize management of state buildings in an effort to save money.

Morgan said last week that he would retire at the end of January because of the governor's proposal to split off six universities of the Board of Regents system and create separate governing boards for each of them.

In an email sent Monday to college presidents in the Tennessee Board of Regents system, outgoing Chancellor John Morgan said an internal analysis showed that each campus' spending on facilities management fell well below the industry standards identified by the state.

He opposed the governor's plan to reconstruct the college board system.

Data on management expenses at the college system and in other state departments will be part of a business justification the state will use as officials deliberate the specifics of an outsourcing plan.

We are very proud of our accomplishments under the Greenlist system and we believe that we will prevail in these cases, Christopher Beard, director of public affairs for SC Johnson, said, while acknowledging that this has been an area that is difficult to navigate.

Virtually all experts agree that the fee-for-service system—doctors are rewarded for the quantity of care rather than its quality of effectiveness—is a primary reason that the cost of care is so high.

The stimulus package provided money to convert the inefficient, paper-driven medical system to electronic records that can be easily viewed and transmitted.

The fundamental fix—reshaping how care is delivered and how doctors are paid in a wasteful, abnormal system—is likely to be achieved only through trial and error and incremental ( ' , 渐进的) gains.

Protecting the union demand sacrifices those students, in effect turning a blind eye to the injustice in the education system.

When you hear people speaking of making a rapid transition toward any type of energy, whether it is a switch from coal to nuclear power, or a switch from gasoline-powered cars to electric cars, or even a switch from an incandescent to a fluorescent light, understanding energy system inertia and momentum can help you decide whether their plans are feasible.

Unfortunately for them ( ' , and often the taxpayers), our energy systems are a bit like an aircraft carrier: they are unbelievably expensive, they are built to last for a very long time, they have a huge amount of inertia ( ' , meaning it takes a lot of energy to set them moving), and they have a lot of momentum once they are set in motion.

The major components of our energy systems, such as fuel production, refining, electrical generation and distribution, are costly installation that have lengthy life spans.

The biggest obstacle to energy transition is that the present energy system is too expensive to replace.

Physical characteristics of moving objects help explain the dynamics of energy systems.

Not only moving objects and people but all systems have momentum.

In physics, moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia and momentum.

For that, we have a robust informal learning system that gives no grades, takes all comers, and is available even on holidays and weekends.

Changing the current energy system requires the systematic training of professionals and skilled labor.

By far the biggest type of momentum that comes into play when it comes to changing our energy systems is economic momentum.

Another type of momentum we have to think about when planning for changes in our energy systems is labor- pool momentum.

After all, we don't speak only of objects or people as having momentum; we speak of entire systems having momentum.

Better design and wiseruser of both mass transit systems and private vehicles will playing an important part in helping America get more out of energy used fortransportation.

"The creation of a system of marine protected areas is a key part of ongoing scientific and policy discussions in CCAMLR," he added.

"We want to reach parents who are not plugged into the system," said Zaharopol.

Second, they rely on a system that has long been marked by a poor relation between national health and social care services.

The Arctic sea ice holds a central position in the Earth's climate system and it's deteriorating faster than expected.

The fundamental fix—reshaping how care is delivered and how doctors are paid in a wasteful, abnormal system—is likely to be achieved only through trial and error and incremental gains.

This system couldn't care less how often you use it.

Unfortunately, however, our education system has not caught up to the approaching reality.

virtually all experts agree that the fee-for-service system— doctors are rewarded for the quantity of care rather than its quality of effectiveness — is a primary reason that the cost of care is so high.
