For years, studies have found that first-generation college students-those who do not have a parent with a college degree-lag other students on a range of education achievement factors. Their grades are lower and their dropout rates are higher. But since such students are most likely to advance economically if they succeed in higher education, colleges and universities have pushed for decades to recruit more of them. This has created "a paradox" in that recruiting first-generation students, but then watching many of them fail, means that higher education has "continued to reproduce and widen, rather than close" achievement gap based on social class, according to the depressing beginning of a paper forthcoming in the journal Psychological Sciense.
But the article is actually quite optimistic, as it outlines a potential solution to this problem, suggesting that an approach(which involves a one-hour, next-to-no-cost program) can close 63 percent of the achievement gap(measured by such factors as grades)between first-generation and other students.
The authors of the paper are from different universities, and their findins are based on a study involving 147 students(who completed the project)at an unnamed private unive rsity.First generation was defined as not having a parent with a fou r-year college degree Most of the first-generation students(59.1 percent) were recipients of Pell Grants，a federal g rant for undergraduates with financial need，while this was true only for 8.6 percent of the students wit at least one parent with a four-year degree
Their thesis-that a relatively modest inte rvention could have a big impact-was based on the view that first-gene ration students may be most lacking not in potential but in practical knowledge about how to deal with the issues that face most college students They cite past resea rch by several authors to show that this is the gap that must be na rrowed to close the achievement gap.
Many first-gene ration students"struggle to navigate the middle-class culture of higher education，learn the'rules of the game，'and take advantage of college resou rces," they write And this becomes more of a problem when collages don't talk about the class advantage and disadvantages of different groups of students Because US colleges and universities seldom acknowledge how social class can affect students' educational expe rience，many first-gene ration students lack sight about why they a re struggling and do not unde rstand how students' like them can improve

While fossil fuels—still generate roughly 85 percent of the world’s energy supply, it’s clearer than ever that the future belongs to renewable sources such as wind and solar. The move to renewables is picking up momentum around the world: They now account for more than half of new power sources going on line.
Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the plummeting prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.
In many parts of the world renewable energy is already a principal energy source. In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.
President Trump has underlined fossil fuels—especially coal—as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation—and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.
The question “What happens when the wind doesn’t blow or the sun doesn’t shine?” has provided a quick put-down for skeptics. But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.
The advance is driven in part by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still a rarity on roads now, this massive investment could change the picture rapidly in coming years.
While there’s a long way to go, the trend lines for renewables are spiking. The pace of change in energy sources appears to be speeding up—perhaps just in time to have a meaningful effect in slowing climate change. What Washington does—or doesn’t do—to promote alternative energy may mean less and less at a time of a global shift in thought.

A century ago, the immigrants from across the Atlantic inclued settlers and sojourners. Along with the many folks looking to make a permanent home in the United States came those who had no intention to stay, and 7millin people arrived while about 2 million departed. About a quarter of all Italian immigrants, for exanmle, eventually returned to Italy for good. They even had an affectionate nickname, “uccelli di passaggio,” birds of passage.
Today, we are much more rigid about immigrants. We divide nemcomers into two categories: legal or illegal, good or bad. We hail them as Americans in the making, or our broken immigrantion system and the long political paralysis over how to fix it. We don’t need more categories, but we need to change the way we think about categories. We need to look beyond strick definitions of legal and illegal. To start, we can recognize the new birds of passage, those living and thriving in the gray areas. We might then begin to solve our immigration challenges.
Crop pickers, violinists, construction workers, entrepreneurs, engineers, home health-care aides and physicists are among today’s birds of passage. They are energetic participants in a global economy driven by the flow of work, money and ideas .They prefer to come and go as opportunity calls them , They can manage to have a job in one place and a family in another.
With or without permission, they straddle laws, jurisdictions and identities with ease. We need them to imagine the United States as a place where they can be productive for a while without committing themselves to staying forever. We need them to feel that home can be both here and there and that they can belong to two nations honorably.
Accommodating this new world of people in motion will require new attitudes on both sides of the immigration battle .Looking beyond the culture war logic of right or wrong means opening up the middle ground and understanding that managing immigration today requires multiple paths and multiple outcomes. Including some that are not easy to accomplish legally in the existing system.

An article in Scientific America has pointed out that empirical research says that, actually, you think you’re more beautiful than you are. We have a deep-seated need to feel good about ourselves and we naturally employ a number of self-enhancing strategies to research into what the call the “above average effect”, or “illusory superiority”, and shown that, for example, 70% of us rate ourselves as above average in leadership, 93% in driving and 85% at getting on well with others—all obviously statistical impossibilities.
We rose tint our memories and put ourselves into self-affirming situations. We become defensive when criticized, and apply negative stereotypes to others to boost our own esteem, we stalk around thinking we’re hot stuff.
Psychologist and behavioral scientist Nicholas Epley oversaw a key studying into self-enhancement and attractiveness. Rather that have people simply rate their beauty compress with others, he asked them to identify an original photogragh of themselves’ from a lineup including versions that had been altered to appear more and less attractive. Visual recognition, reads the study, is “an automatic psychological process occurring rapidly and intuitively with little or no apparent conscious deliberation”. If the subjects quickly chose a falsely flattering image- which must did- they genuinely believed it was really how they looked. Epley found no significant gender difference in responses. Nor was there any evidence that, those who self-enhance the must (that is, the participants who thought the most positively doctored picture were real) were doing so to make up for profound insecurities. In fact those who thought that the images higher up the attractiveness scale were real directly corresponded with those who showed other makers for having higher self-esteem. “I don’t think the findings that we having have are any evidence of personal delusion”, says Epley. “It’s a reflection simply of people generally thinking well of themselves’. If you are depressed, you won’t be self-enhancing. Knowing the results of Epley ‘s study,it makes sense that why people heat photographs of themselves Viscerally-on one level, they don’t even recognise the person in the picture as themselves, Facebook therefore ,is a self-enhancer’s paradise,where people can share only the most flattering photos, the cream of their wit ,style ,beauty, intellect and lifestyle it’s not that people’s profiles are dishonest,says catalina toma of Wiscon—Madison university ,”but they portray an idealized version of themselves.
