In 1961, when President Kennedy declared that America would send a man to the moon by the decade's end, those words, too, had a dreamlike quality. They resonated(共鸣) with optimism and ambition in much the same way as the most famous dream speech of all, delivered by Martin Luther King Jr. two years later. By the end of the decade, both visions had turned out concrete results and transformed American society. And yet in many ways the two dreams ended up conflicting with each other. The fight for racial and economic equality is intensely practical and immediate in its impact. The urge to explore space is just the opposite. It is actually unrealistic in its aims.

When the dust settled, the space dreamers lost out. There was no grand follow-up to the Apollo missions. The technologically compromised（妥协） space shuttle program has just come to an end, with no successor. The endless argument is that funds are tight, that we have more pressing problems here on Earth. Among the current concerns about the federal deficit (赤字), reaching toward the stars seems an unnecessary luxury—as if saving one-thousandth of a single year's budget would solve our problems.

But human innovation struggles on. NASA is developing a series of robotic devices that will get the most bang from a buck. They will serve as modern Magellans, mapping out the solar system for whatever explorers follow, whether man or machine. On the flip side, companies like Virgin Galactic are designing a bottom-up attack on the space dream by making it a reality to the public. Private spaceflight could lie within reach of rich civilians in a few years. Another decade or two and it could go mainstream.

The space dreamers end up benefiting all of us—not just because of the way they expand human knowledge, or because of the technologies they produce, but because the two types of dreams feed on each other. Both Martin Luther King and John Kennedy appealed to the idea that humans can get over what were once considered inborn limitations. Today we face seeming challenges in energy, the environment, healthcare. Tomorrow we will overcome these as well, and the dreamers will deserve a lot of the credit. The more evidence we collect that our species is capable of greatness, the more we will actually achieve it.

The initial study was conducted in 2017 with 218 families. Additionally, data collected in 2013 were also available. One parent from each family completed the Child Feeding Questionnaire, as well as the Child Feeding Practices Questionnaire, and both adolescent and parent completed the Dutch Eating Behavior Questionnaire. The adolescent's body weight and height were measured by researchers. The four years between 2013 — 2017 covered the years from late childhood to mid-teens.

The study found that when parents used food as a reward, or restricted and monitored an adolescent's access to food, this was associated with an increased tendency by the adolescent to use emotional eating as a strategy to deal with their emotions. On the other hand, involving a child in meal preparations had the opposite effect — it was associated with higher levels of emotional regulation and lower levels of emotional eating in the adolescent participants.

Additionally, the researchers found a negative link between the extent to which parents restrained (克制) their own eating behavior and the use of emotional eating by their adolescent children. This means that the more a parent limited his or her own consumption of food for the purpose of health or dietary goals, the less the adolescent child used emotional eating as a means of regulating his or her own emotions.

According to study lead author Joanna Klosowska, restrictive parenting was most damaging, whereas restrained eating by the parent seemed to be the most beneficial. "Additional research is required to understand the way in which restrained eating demonstrated by a parent impacts the emotional eating of a child," said Klosowska.

Several factors account for high student loan debt. One is that employers everywhere have increased their demands for skilled workers, making higher education a requirement for many jobs. The students, however, after graduation, often find that their country's economy is not strong enough to support their financial needs, so their ability to pay back the loan becomes a problem.

To solve the problem, many countries are seeking their ways. Australia has developed a system where students do not have to pay anything back until they are earning at least $40,000 a year. In America, several candidates running for president in the 2020 election have offered more extreme solutions that all or at least some of these loans will be forgiven.

Some professors in several universities recently studied what the effects of debt forgiveness might be. They found that, overall, sudden debt relief greatly improved the borrowers' lives. Not only did they have more money, but they were more likely to move to a new area and seek better paying work.

Yet the professors' research doesn't include what might happen to financial institutions or the overall economy if debt were totally forgiven. It only looks at how debt forgiveness would help the borrowers. They warn of some other possible negative effects. If a borrower knew that if he ran into any trouble he would be saved because he could get the debt relief, then he might actually become more reckless (轻率的) with his borrowing in the future.

No matter what, the professors agree that if countries do decide to approve some student debt relief the neediest students should be helped first.
