These patterns suggest that some types of mental flexibility decrease relatively early in adulthood, but that the amount of knowledge one has, and the effectiveness of integrating it with one's abilities, may increase throughout all of adulthood if there are no diseases, Salthouse said in a news release.

Pre-K advocates insist it is proven and will succeed if integrated with the rest of the child's schooling.

Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.

It will not be difficult to make learning a source of joy if educators change their way of thinking.

Isn't this the same crowd that rails against processed junk and champions craft cooking? And isn't this the generation who say they're concerned about their health and the well-being of the planet? If these are truly the values of many young people, then their behavior doesn't match their beliefs.

If you spend much time with educators and policy makers, you'll hear a lot of the following words: standards, results, skills, self-control, accountability, and so on.

Unless renewables become cheap enough that substantial carbon deposits are left underground for a very long time, if not forever, the planet will likely be exposed to potentially catastrophic climate risks.

The challenge is if certain types of people are doing something, it's difficult for other people to break into it, said Po-Shen Loh, the head coach of last year's winning U.S.Math Olympiad team.

Progress in the development of renewables could be fragile, however, if fossil fuel prices remain low for long.

Participation grows through friends and networks and if you realize that's how they're growing, you can start to take action and bring in other students, he said.

Moreover, nonparticipation by nations, if sufficiently widespread, can undermine the political will of participating countries to act.

If you look at a lot of low-income communities in the United States, there are programs that are serving them, but they're primarily centered around ‘Let's get these kids' grades up,' and not around ‘Let's get these kids access to the same kinds of opportunities as more-affluent kids,' said Daniel Zaharopol, the founder and executive director of the program.

If not corrected by the appropriate carbon price, low fossil fuel prices are not accurately signaling to markets the true social profitability of clean energy.

If Paris was cast aside, the tradition of beauty was also to some degree slighted.

Greenhouse gas emissions, if not properly dealt with, will pose endless risks for mankind.

If you think this does not apply to you, then here is a simple test to show you are wrong.

Research finds that if employees suffer from high stress, they will be less motivated, less productive and more likely to quit.

Perhaps the reason why so many universities offer their students so little is they know studying at a top university remains a brilliant investment even if you don't learn anything.

If you make clinical predictions based on somebody's race, you're going to be wrong a good chunk of the time, Yudell told Live Science.

If going to university doesn't work out, students pay very little--if any--of their tuition fees back: you only start repaying when you are earning ￡21,000 a year.

Sternberg would argue it’s not love if you don’t call it love and if you don’t have some desire to maintain the relationship.

So what I’ve done is I’ve taken Sternberg’s three elements of love: intimacy, passion and commitment, and I’ve listed out the different kinds of relationships you would have if you had zero, one, two or three out of the three elements.

So if you have all three of these, intimacy, passion and commitment, in Sternberg’s theory you have love.

Now what’s interesting about the theory is what do you have if you only have one out of three or two out of three? What do you have and how is it different if you have a different two out of three? What’s interesting about this kind of theorizing is it gives rise to many different combinations that can be quite interesting when you break them down and start to look at them carefully.

If children are turning to athletes as role models, it’s in their best interest if their idols are consistent.

He argued that you don’t have love if you don’t have all three of these elements.

We worry most about now because if we don't survive for the next minute, we're not going to be around in ten years' time, says Professor Elke Weber of the Centre for Research on Environmental Decisions at Columbia University in New York.

We found that when we taught participants to ask What if? and How can? questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit − asking more questions, performing more experiments and making better inter pretations of their results.

These students need to build skills and knowledge during college if they are to use their degrees as a stepping- stone to middle-class mobility.

The problem with lighting, if it arises, often doesn't lie in light sources but in their applications.

The incandescent light bulb, invented by Thomas Edison, which came to be the symbol of inspiration, has been developed into hundreds, if not thousands, of forms.

That is because the engineers, designers, regulators, operators, and all of the other skilled people needed for the new energy industry are specialists who have to be trained first ( ' , or retrained, if they are the ones being laid off in some related industry), and education, like any other complicated endeavor, takes times.

So what factors, at the community level, do predict if poor children will move up the economic ladder as adults? What explains, for instance, why the Salt Lake City metro area is one of the 100 largest metropolitan areas most likely to lift the fortunes of the poor and the Atlanta metro area is one of the least likely?Harvard economist Raj Chetty has pointed to economic and racial segregation, community density, the size of a community's middle class, the quality of schools, community religiosity, and family structure, which he calls the single strongest correlate of upward mobility.

Instead of normalising the undesirable behaviour, the message needs to marginalise it, for example, by stating that if even one person buys yet another SUV, it reduces our ability to be energy-independent.

If, for example, building codes included green construction guidelines, most developers would be too lazy to challenge them.

If we can help to direct students to more of these types of campuses and help students to understand them to be realistic and accessible places, have them apply to these schools at greater frequency and ultimately get in and enroll, we are going to raise the success rate, Rubinoff said, citing a variety of colleges ranging from large state institutions to smaller private schools.

If the Thames were lapping around Big Ben, Londoners would face up to the problem of emissions pretty quickly.

If the CFL should be used for lighting a particular space, or an object within that space, the fixture must be designed to work with that lamp, and that fixture with the room.

He said doctors risked losing the trust of patients if they told patients, I'm not going to do what I think is best for you because 1 think it's bad for the healthcare budget in Massachusetts.

For all the new attention devoted to the 1 percent, a new dataset from the Equality of Opportunity Project at Harvard and Berkeley suggests that, if we care about upward mobility overall, we're vastly exaggerating the dangers of the rich-poor gap.

Erica is proof that a great-grandmother can help to lead the revolution if you get the psychology right — in this case, by matching her enthusiasm for the environment with a fondness for organising groups.

And if we're not going to make rational decisions about the future, others may have to help us to do so.

Team management calls for new skills if personnel potential is tobe fully realized.

If we could figure out how to improve the efficiency with which we use energy, we can do a lot of work with the energy that is available.

If a team manager exemplifies such qualities, then the team as a whole would be better able to realize their potential and achieve their objectives.

And if the sources don't give you an accurate depiction, your stereotype won't be accurate.

And if you suspected that the workplace had gotten more stressful than it was just a few decades ago, you're right.

And just think of how wonderful it would be if you had a live-in robot.

And that's going to affect us, as if we didn't have enough problems on our hands.

And the funny thing is that if you love what you do and are really passionate about it and work really hard, the money kind of comes automatically.

And we also need to plan ahead so that we're in a position to deal with the likely levels of climate change which are already inevitable and even more so too for the levels that are likely if we don't get those global agreements.

And, if you’re not sure, in is always a good idea to check with your primary care provider.

Bottom line, if you think you need more protein in your diet, consider these questions: Are you an extreme athlete; are you recovering from injury or surgery; or are you 60 years or older?

But if the confrontation has crystallized in this latest battle, it may already be heading toward a predictable conclusion: In the long run, the tech companies are destined to emerge victorious.

But if we're talking about the benefits to society, the only thing that matters is what the major enables the student to produce for society.

But most of all we need to keep the long-term perspective in mind: that even if computers will outsmart us, we can still be the most creative.

But put a deadline on the input stage and arrive at a decision, even if it's a decision that doesn't have consensus.
