His twelve daughters acted as a spur to his genius, and he looked with satisfaction in the mirror each morning at the face of a warrior going out to do battle. Nawab of course knew that he must proliferate his sources of revenue\u2014the salary he received from K. K. Harouni for tending the tube wells would not even begin to suffice. He set up a little one-room flour mill, run off a condemned electric motor\u2014condemned by him.He tried his hand at fish-farming in a little pond at the edge of his master\u2019s fields. He bought broken radios, fixed them, and resold them. He did not demur even when asked to fix watches, though that enterprise did spectacularly badly, and in fact earned him more kicks than kudos, for no watch he took apart ever kept time again.<\/p>\n\n\n\n
K. K. Harouni rarely went to his farms, but lived mostly in Lahore. Whenever the old man visited, Nawab would place himself night and day at the door leading from the servants\u2019 sitting area into the walled grove of ancient banyan trees where the old farmhouse stood. Grizzled, his peculiar aviator glasses bent and smudged, Nawab tended the household machinery, the air conditioners, water heaters, refrigerators, and water pumps, like an engineer tending the boilers on a foundering steamer in an Atlantic gale. By his superhuman efforts he almost managed to maintain K. K. Harouni in the same mechanical cocoon, cooled and bathed and lighted and fed, that the landowner enjoyed in Lahore.<\/p>\n\n\n\n
Harouni of course became familiar with this ubiquitous man, who not only accompanied him on his tours of inspection, but morning and night could be found standing on the master bed rewiring the light fixture or in the bathroom poking at the water heater. Finally, one evening at teatime, gauging the psychological moment, Nawab asked if he might say a word. The landowner, who was cheerfully filing his nails in front of a crackling rosewood fire, told him to go ahead.<\/p>\n\n\n\n
\u201cSir, as you know, your lands stretch from here to the Indus, and on these lands are fully seventeen tube wells, and to tend these seventeen tube wells there is but one man, me, your servant. In your service I have earned these gray hairs\u201d\u2014here he bowed his head to show the gray\u2014\u201cand now I cannot fulfill my duties as I should. Enough, sir, enough. I beg you, forgive me my weakness. Better a darkened house and proud hunger within than disgrace in the light of day.Release me, I ask you, I beg you.\u201d<\/p>\n\n\n\n
The old man, well accustomed to these sorts of speeches, though not usually this florid, filed away at his nails and waited for the breeze to stop.\u201cWhat\u2019s the matter, Nawabdin?\u201d<\/p>\n\n\n\n
\u201cMatter, sir? O what could be the matter in your service. I\u2019ve eaten your salt for all my years. But sir,on the bicycle now, with my old legs, and with the many injuries I\u2019ve received when heavy machinery fell on me\u2014I cannot any longer bicycle about like a bridegroom from farm to farm, as I could when I first had the good fortune to enter your employment.I beg you, sir, let me go.\u201d<\/p>\n\n\n\n
\u201cAnd what\u2019s the solution?\u201d asked Harouni, seeingthat they had come to the crux. He didn\u2019t particularly care one way or the other, except that it touched on his comfort\u2014a matter of great interest to him.<\/p>\n\n\n\n
\u201cWell, sir, if I had a motorcycle, then I could somehow limp along, at least until I train up some younger man.\u201d<\/p>\n\n\n\n
The crops that year had been good, Harouni feltexpansive in front of the fire, and so, much to the disgust of the farm managers, Nawab received a brand-new motorcycle, a Honda 70. He even managed to extract an allowance for gasoline.<\/p>\n\n\n\n
The motorcycle increased his status, gave him weight, so that people began calling him \u201cUncle,\u201d and asking his opinion on world affairs, about which he knew absolutely nothing. He could now range further, doing a much wider business. Best of all,now he could spend every night with his wife, who had begged to live not on the farm but near her family in Firoza, where also they could educate at least the two eldest daughters. A long straight road ran from the canal head works near Firoza all the way to the Indus, through the heart of the K. K. Harouni lands. Nawab would fly down this road on his new machine, with bags and cloths hanging from every knob and brace, so that the bike, when he hit a bump,seemed to be flapping numerous small vestigial wings; and with his grinning face, as he rolled up to whichever tube well needed servicing, with his ears almost blown off, he shone with the speed of his arrival.<\/p>\n\n\n\n
PASSAGE 2<\/strong><\/h3>\n\n\n\nThis passage is adapted from Stephen Coleman, ScottAnthony, and David E. Morrison, \u201cPublic Trust in the News.\u201d\u00a92009 by Stephen Coleman.<\/em><\/p>\n\n\n\nThe news is a form of public knowledge.Unlike personal or private knowledge (such as of one\u2019s friends and family; the conduct of a private hobby; a secret liaison), public know ledge increases in value as it is shared by more people. The date of an election and the claims of rival candidates;the causes and consequences of an environmental disaster; a debate about how to frame a particular law; the latest reports from a war zone\u2014these are all examples of public knowledge that people are generally expected to know in order to be considered informed citizens. Thus, in contrast to personal or private knowledge, which is generally left to individuals to pursue or ignore, public knowledge is promoted even to those who might not think it matters to them. In short, the circulation of public knowledge, including the news, is generally regarded as a public good which cannot be solely demand-driven.<\/p>\n\n\n\n
The production, circulation, and reception of public knowledge is a complex process. It is generally accepted that public knowledge should be authoritative, but there is not always common agreement about what the public needs to know, who is best placed to relate and explain it, and how authoritative reputations should be determined and evaluated. Historically, newspapers such as The Times<\/em> and broadcasters such as the BBC were widely regarded as the trusted shapers of authoritative agendas and conventional wisdom. They embodied the Oxford English Dictionary\u2019s<\/em> definition of authority as the \u201cpower over, or title to influence, the opinions of others.\u201d As part of the general process of the transformation of authority whereby there has been a reluctance to uncritically accept traditional sources of public knowledge, the demand has been for all authority to make explicit the frames of value which determine their decisions. Centres of news production, as our focus groups show, have not been exempt from this process. Not surprisingly perhaps some news journalists feel uneasy about this renegotiation of their authority:<\/p>\n\n\n\nEditors are increasingly casting a glance at the\u201cmost read\u201d lists on their own and other websites to work out which stories matter to readers and viewers. And now the audience\u2014which used to know its place\u2014is being asked to act as a kind of journalistic ombudsman, ruling on our credibility (broadcast journalist, 2008).<\/p>\n\n\n\n
The result of democratising access to TV news could be political disengagement by the majority and a dumbing down through a popularity contest of stories (online news editor, 2007).<\/p>\n\n\n\n
Despite the rhetorical bluster of these statements,they amount to more than straightforward professional defensiveness. In their reference to an audience \u201cwhich used to know its place\u201d and conflation between democratisation and \u201cdumbing down,\u201d they are seeking to argue for a particular mode of public knowledge: one which is shaped by experts, immune from populist pressures; and disseminated to attentive, but mainly passive recipients. It is a view of citizenship that closes down opportunities for popular involvement in the making of public knowledge by reinforcing the professional claims of experts. The journalists quoted above are right to feel uneasy, for there is, at almost every institutional level in contemporary society, scepticism towards the epistemological authority of expert elites. There is a growing feeling, as expressed by several of our focus group participants, that the news media should be \u201cinformative rather than authoritative\u201d; the job of journalists should be to\u201cgive the news as raw as it is, without putting their slant on it\u201d; and people should be given \u201csufficient information\u201d from which \u201cwe would be able to form opinions of our own.\u201d<\/p>\n\n\n\n
At stake here are two distinct conceptions of authority. The journalists we have quoted are resistant to the democratisation of news:the supremacy of the clickstream (according to which editors raise or lower the profile of stories according to the number of readers clicking on them online); the parity of popular culture with \u201cserious\u201dnews; the demands of some audience members for raw news rather than constructed narratives.<\/p>\n\n\n\n

<\/figure>\n\n\n\nPassage 3<\/strong><\/h2>\n\n\n\nThis passage is adapted from Elsa Youngsteadt, \u201cDecoding aFlower\u2019s Message.\u201d \u00a92012 by Sigma Xi, The ScientificResearch Society.<\/em><\/p>\n\n\n\nTexas gourd vines unfurl their large, flared blossoms in the dim hours before sunrise. Until they close at noon, their yellow petals and mild, squashy aroma attract bees that gather nectar and shuttle pollen from flower to flower. But \u201cwhen you advertise [to pollinators], you advertise in an open communication network,\u201d says chemical ecologist Ian Baldwin of the Max Planck Institute for Chemical Ecology in Germany. \u201cYou attract not just the good guys, but you also attract the bad guys.\u201d Fora Texas gourd plant, striped cucumber beetles are among the very bad guys. They chew up pollen and petals, defecate in the flowers and transmit the dreaded bacterial wilt disease, an infection that can reduce an entire plant to a heap of collapsed tissue in mere days.<\/p>\n\n\n\n
In one recent study, Nina Theis and Lynn Adler took on the specific problem of the Texas gourd\u2014how to attract enough pollinators but not too many beetles. The Texas gourd vine\u2019s main pollinators are honey bees and specialized squash bees, which respond to its floral scent. The aroma includes 10 compounds, but the most abundant\u2014and the only one that lures squash bees into traps\u2014is 1,4-dimethoxybenzene.<\/p>\n\n\n\n
Intuition suggests that more of that aroma should be even more appealing to bees. \u201cWe have this assumption that a really fragrant flower is going to attract a lot of pollinators,\u201d says Theis, a chemical ecologist at Elms College in Chicopee,Massachusetts. But, she adds, that idea hasn\u2019t really been tested\u2014and extra scent could well call in more beetles, too. To find out, she and Adler planted 168 Texas gourd vines in an Iowa field and,throughout the August flowering season, made halfthe plants more fragrant by tucking dimethoxybenzene-treated swabs deep inside their flowers. Each treated flower emitted about 45 times more fragrance than a normal one; the other half of the plants got swabs without fragrance.<\/p>\n\n\n\n
The researchers also wanted to know whether extra beetles would impose a double cost by both damaging flowers and deterring bees, which might not bother to visit (and pollinate) a flower laden with other insects and their feces. So every half hour throughout the experiments, the team plucked all the beetles off of half the fragrance-enhanced flowers and half the control flowers, allowing bees to respond to the blossoms with and without interference bybeetles.<\/p>\n\n\n\n
Finally, they pollinated by hand half of the female flowers in each of the four combinations of fragrance and beetles. Hand-pollinated flowers should develop into fruits with the maximum number of seeds,providing a benchmark to see whether the fragrance-related activities of bees and beetles resulted in reduced pollination.\u201cIt was very labor intensive,\u201d says Theis.\u201cWe would be out there at four in the morning, three in the morning, to try and set up before these flowers open.\u201d As soon as they did, the team spent the next several hours walking from flower to flower,observing each for two-minute intervals \u201cand writing down everything we saw.\u201d<\/p>\n\n\n\n
What they saw was double the normal number of beetles on fragrance-enhanced blossoms.Pollinators, to their surprise, did not prefer the highly scented flowers. Squash bees were indifferent,and honey bees visited enhanced flowers less often than normal ones. Theis thinks the bees were repelled not by the fragrance itself, but by the abundance of beetles: The data showed that the more beetles on a flower, the less likely a honey bee was to visit it.<\/p>\n\n\n\n
That added up to less reproduction for fragrance-enhanced flowers. Gourds that developed from those blossoms weighed 9 percent less and had,on average, 20 fewer seeds than those from normal flowers. Hand pollination didn\u2019t rescue the seed set,indicating that beetles damaged flowers directly\u2014regardless of whether they also repelled pollinators. (Hand pollination did rescue fruit weight, a hard-to-interpret result that suggests that lost bee visits did somehow harm fruit development.)<\/p>\n\n\n\n
The new results provide a reason that Texas gourd plants never evolved to produce a stronger scent: \u201cIf you really ramp up the odor, you don\u2019t get more pollinators, but you can really get ripped apart by your enemies,\u201d says Rob Raguso, a chemical ecologist at Cornell University who was not involved in the Texas gourd study.<\/p>\n\n\n\n
Passage 4<\/strong><\/h2>\n\n\n\nPassage 1 is adapted from Abraham Lincoln, \u201cAddress to theYoung Men\u2019s Lyceum of Springfield, Illinois.\u201d Originallydelivered in 1838. Passage 2 is from Henry David Thoreau,\u201cResistance to Civil Government.\u201d Originally publishedin 1849.<\/em><\/p>\n\n\n\nPassage 1<\/strong><\/p>\n\n\n\nLet every American, every lover of liberty, every well wisher to his posterity, swear by the blood of the Revolution, never to violate in the least particular,the laws of the country; and never to tolerate their violation by others. As the patriots of seventy-six did to the support of the Declaration of Independence, so to the support of the Constitution and Laws, let every American pledge his life, his property, and his sacred honor;\u2014let every man remember that to violate the law, is to trample on the blood of his father, and to tear the character of his own, and his children\u2019s liberty. Let reverence for the laws, be breathed bye very American mother, to the lisping babe, that prattles on her lap\u2014let it be taught in schools, in seminaries, and in colleges;\u2014let it be written in Primers, spelling books, and in Almanacs;\u2014let it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice. And, in short,let it become the political religion of the nation;and let the old and the young, the rich and the poor,the grave and the gay, of all sexes and tongues, and colors and conditions, sacrifice unceasingly upon its altars….<\/p>\n\n\n\n
When I so pressingly urge a strict observance of all the laws, let me not be understood as saying there are no bad laws, nor that grievances may not arise,for the redress of which, no legal provisions have been made. I mean to say no such thing. But I do mean to say, that, although bad laws, if they exist,should be repealed as soon as possible, still while they continue in force, for the sake of example, they should be religiously observed. So also in unprovided cases. If such arise, let proper legal provisions be made for them with the least possible delay; but, till then, let them if not too intolerable, be borne with.<\/p>\n\n\n\n
There is no grievance that is a fit object of redress by mob law. In any case that arises, as for instance,the promulgation of abolitionism, one of two positions is necessarily true; that is, the thing is right within itself, and therefore deserves the protection of all law and all good citizens; or, it is wrong, and therefore proper to be prohibited by legal enactments; and in neither case, is the inter position of mob law, either necessary, justifiable, or excusable.<\/p>\n\n\n\n
Passage 2<\/strong><\/p>\n\n\n\nUnjust laws exist; shall we be content to obey them, or shall we endeavor to amend them, and obey them until we have succeeded, or shall we transgress them at once? Men generally, under such a government as this, think that they ought to wait until they have persuaded the majority to alter them.They think that, if they should resist, the remedy would be worse than the evil. But it is the fault of the government itself that the remedy is worse than the evil. It makes it worse. Why is it not more apt to anticipate and provide for reform? Why does it not cherish its wise minority? Why does it cry and resist before it is hurt?…<\/p>\n\n\n\n
If the injustice is part of the necessary friction of the machine of government, let it go, let it go;perchance it will wear smooth\u2014certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself,then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law. Let your life be a counter friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.<\/p>\n\n\n\n
As for adopting the ways which the State has provided for remedying the evil, I know not of such ways. They take too much time, and a man\u2019s life will be gone. I have other affairs to attend to. I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad. A man has not everything to do, but something; and because he cannot do everything, it is not necessary that he should do something wrong….<\/p>\n\n\n\n
I do not hesitate to say, that those who call themselves Abolitionists should at once effectually withdraw their support, both in person and property,from the government . . . and not wait till they constitute a majority of one, before they suffer the right to prevail through them. I think that it is enough if they have God on their side, without waiting for that other one. Moreover, any man more right than his neighbors constitutes a majority of one already.<\/p>\n\n\n\n
Passage 5<\/strong><\/h2>\n\n\n\nThis passage is adapted from Kevin Bullis, \u201cWhat Tech IsNext for the Solar Industry?\u201d \u00a92013 by MIT TechnologyReview.<\/em><\/p>\n\n\n\nSolar panel installations continue to grow quickly,but the solar panel manufacturing industry is in the doldrums because supply far exceeds demand. The poor market may be slowing innovation, but advances continue; judging by the mood this week at the IEEE Photovoltaics Specialists Conference in Tampa, Florida, people in the industry remain optimistic about its long-term prospects.<\/p>\n\n\n\n
The technology that\u2019s surprised almost everyone is conventional crystalline silicon. A few years ago,silicon solar panels cost $4 per watt, and Martin Green, professor at the University of New South Wales and one of the leading silicon solar panel researchers, declared that they\u2019d never go below $1 a watt. \u201cNow it\u2019s down to something like 50 cents a watt, and there\u2019s talk of hitting 36 cents per watt,\u201d he says.<\/p>\n\n\n\n
The U.S. Department of Energy has set a goal of reaching less than $1 a watt\u2014not just for the solar panels, but for complete, installed systems\u2014by 2020.Green thinks the solar industry will hit that target even sooner than that. If so, that would bring the direct cost of solar power to six cents per kilowatt-hour, which is cheaper than the average cost expected for power from new natural gas power plants.<\/p>\n\n\n\n
All parts of the silicon solar panel industry have been looking for ways to cut costs and improve the power output of solar panels, and that\u2019s led to steady cost reductions. Green points to something as mundane as the pastes used to screen-print some of the features on solar panels. Green\u2019s lab built a solar cell in the 1990s that set a record efficiency for silicon solar cells\u2014a record that stands to this day. To achieve that record, he had to use expensive lithography techniques to make fine wires for collecting current from the solar cell. But gradual improvements have made it possible to use screen printing to produce ever-finer lines. Recent research suggests that screen-printing techniques can produce lines as thin as 30 micrometers\u2014about the width of the lines Green used for his record solar cells, but at costs far lower than his lithography techniques.<\/p>\n\n\n\n
Meanwhile, researchers at the National Renewable Energy Laboratory have made flexible solar cells on anew type of glass from Corning called Willow Glass,which is thin and can be rolled up. The type of solar cell they made is the only current challenger to silicon in terms of large-scale production\u2014thin-film cadmium telluride. Flexible solar cells could lower the cost of installing solar cells, making solar powercheaper.<\/p>\n\n\n\n
One of Green\u2019s former students and colleagues, Jianhua Zhao, cofounder of solar panel manufacturer China Sunergy, announced this week that he is building a pilot manufacturing line for a two-sided solar cell that can absorb light from both the front and back. The basic idea, which isn\u2019t new, is that during some parts of the day, sunlight falls on the land between rows of solar panels in a solar power plant. That light reflects onto the back of the panels and could be harvested to increase the power output.This works particularly well when the solar panels are built on sand, which is highly reflective. Where a one-sided solar panel might generate 340 watts, a two-sided one might generate up to 400 watts. He expects the panels to generate 10 to 20 percent more electricity over the course of a year.<\/p>\n\n\n\n
Even longer-term, Green is betting on silicon,aiming to take advantage of the huge reductions in cost already seen with the technology. He hopes to greatly increase the efficiency of silicon solar panels by combining silicon with one or two other semiconductors, each selected to efficiently convert apart of the solar spectrum that silicon doesn\u2019t convert efficiently. Adding one semiconductor could boost efficiencies from the 20 to 25 percent range to around 40 percent. Adding another could make efficiencies as high as 50 percent feasible, which would cut in half the number of solar panels needed for a given installation. The challenge is to produce good connections between these semiconductors,something made challenging by the arrangement of silicon atoms in crystalline silicon.<\/p>\n\n\n\n![\"\"](\"https:\/\/blog.ivy-way.com\/wp-content\/uploads\/2020\/07\/\u8a3b\u89e3-2020-07-21-113131.png\")

His twelve daughters acted as a spur to his genius, and he looked with satisfaction in the mirror each morning at the face of a warrior going out to do battle. Nawab of course knew that he must proliferate his sources of revenue\u2014the salary he received from K. K. Harouni for tending the tube wells would not even begin to suffice. He set up a little one-room flour mill, run off a condemned electric motor\u2014condemned by him.He tried his hand at fish-farming in a little pond at the edge of his master\u2019s fields. He bought broken radios, fixed them, and resold them. He did not demur even when asked to fix watches, though that enterprise did spectacularly badly, and in fact earned him more kicks than kudos, for no watch he took apart ever kept time again.<\/p>\n\n\n\n
K. K. Harouni rarely went to his farms, but lived mostly in Lahore. Whenever the old man visited, Nawab would place himself night and day at the door leading from the servants\u2019 sitting area into the walled grove of ancient banyan trees where the old farmhouse stood. Grizzled, his peculiar aviator glasses bent and smudged, Nawab tended the household machinery, the air conditioners, water heaters, refrigerators, and water pumps, like an engineer tending the boilers on a foundering steamer in an Atlantic gale. By his superhuman efforts he almost managed to maintain K. K. Harouni in the same mechanical cocoon, cooled and bathed and lighted and fed, that the landowner enjoyed in Lahore.<\/p>\n\n\n\n
Harouni of course became familiar with this ubiquitous man, who not only accompanied him on his tours of inspection, but morning and night could be found standing on the master bed rewiring the light fixture or in the bathroom poking at the water heater. Finally, one evening at teatime, gauging the psychological moment, Nawab asked if he might say a word. The landowner, who was cheerfully filing his nails in front of a crackling rosewood fire, told him to go ahead.<\/p>\n\n\n\n
\u201cSir, as you know, your lands stretch from here to the Indus, and on these lands are fully seventeen tube wells, and to tend these seventeen tube wells there is but one man, me, your servant. In your service I have earned these gray hairs\u201d\u2014here he bowed his head to show the gray\u2014\u201cand now I cannot fulfill my duties as I should. Enough, sir, enough. I beg you, forgive me my weakness. Better a darkened house and proud hunger within than disgrace in the light of day.Release me, I ask you, I beg you.\u201d<\/p>\n\n\n\n
The old man, well accustomed to these sorts of speeches, though not usually this florid, filed away at his nails and waited for the breeze to stop.\u201cWhat\u2019s the matter, Nawabdin?\u201d<\/p>\n\n\n\n
\u201cMatter, sir? O what could be the matter in your service. I\u2019ve eaten your salt for all my years. But sir,on the bicycle now, with my old legs, and with the many injuries I\u2019ve received when heavy machinery fell on me\u2014I cannot any longer bicycle about like a bridegroom from farm to farm, as I could when I first had the good fortune to enter your employment.I beg you, sir, let me go.\u201d<\/p>\n\n\n\n
\u201cAnd what\u2019s the solution?\u201d asked Harouni, seeingthat they had come to the crux. He didn\u2019t particularly care one way or the other, except that it touched on his comfort\u2014a matter of great interest to him.<\/p>\n\n\n\n
\u201cWell, sir, if I had a motorcycle, then I could somehow limp along, at least until I train up some younger man.\u201d<\/p>\n\n\n\n
The crops that year had been good, Harouni feltexpansive in front of the fire, and so, much to the disgust of the farm managers, Nawab received a brand-new motorcycle, a Honda 70. He even managed to extract an allowance for gasoline.<\/p>\n\n\n\n
The motorcycle increased his status, gave him weight, so that people began calling him \u201cUncle,\u201d and asking his opinion on world affairs, about which he knew absolutely nothing. He could now range further, doing a much wider business. Best of all,now he could spend every night with his wife, who had begged to live not on the farm but near her family in Firoza, where also they could educate at least the two eldest daughters. A long straight road ran from the canal head works near Firoza all the way to the Indus, through the heart of the K. K. Harouni lands. Nawab would fly down this road on his new machine, with bags and cloths hanging from every knob and brace, so that the bike, when he hit a bump,seemed to be flapping numerous small vestigial wings; and with his grinning face, as he rolled up to whichever tube well needed servicing, with his ears almost blown off, he shone with the speed of his arrival.<\/p>\n\n\n\n
PASSAGE 2<\/strong><\/h3>\n\n\n\nThis passage is adapted from Stephen Coleman, ScottAnthony, and David E. Morrison, \u201cPublic Trust in the News.\u201d\u00a92009 by Stephen Coleman.<\/em><\/p>\n\n\n\nThe news is a form of public knowledge.Unlike personal or private knowledge (such as of one\u2019s friends and family; the conduct of a private hobby; a secret liaison), public know ledge increases in value as it is shared by more people. The date of an election and the claims of rival candidates;the causes and consequences of an environmental disaster; a debate about how to frame a particular law; the latest reports from a war zone\u2014these are all examples of public knowledge that people are generally expected to know in order to be considered informed citizens. Thus, in contrast to personal or private knowledge, which is generally left to individuals to pursue or ignore, public knowledge is promoted even to those who might not think it matters to them. In short, the circulation of public knowledge, including the news, is generally regarded as a public good which cannot be solely demand-driven.<\/p>\n\n\n\n
The production, circulation, and reception of public knowledge is a complex process. It is generally accepted that public knowledge should be authoritative, but there is not always common agreement about what the public needs to know, who is best placed to relate and explain it, and how authoritative reputations should be determined and evaluated. Historically, newspapers such as The Times<\/em> and broadcasters such as the BBC were widely regarded as the trusted shapers of authoritative agendas and conventional wisdom. They embodied the Oxford English Dictionary\u2019s<\/em> definition of authority as the \u201cpower over, or title to influence, the opinions of others.\u201d As part of the general process of the transformation of authority whereby there has been a reluctance to uncritically accept traditional sources of public knowledge, the demand has been for all authority to make explicit the frames of value which determine their decisions. Centres of news production, as our focus groups show, have not been exempt from this process. Not surprisingly perhaps some news journalists feel uneasy about this renegotiation of their authority:<\/p>\n\n\n\nEditors are increasingly casting a glance at the\u201cmost read\u201d lists on their own and other websites to work out which stories matter to readers and viewers. And now the audience\u2014which used to know its place\u2014is being asked to act as a kind of journalistic ombudsman, ruling on our credibility (broadcast journalist, 2008).<\/p>\n\n\n\n
The result of democratising access to TV news could be political disengagement by the majority and a dumbing down through a popularity contest of stories (online news editor, 2007).<\/p>\n\n\n\n
Despite the rhetorical bluster of these statements,they amount to more than straightforward professional defensiveness. In their reference to an audience \u201cwhich used to know its place\u201d and conflation between democratisation and \u201cdumbing down,\u201d they are seeking to argue for a particular mode of public knowledge: one which is shaped by experts, immune from populist pressures; and disseminated to attentive, but mainly passive recipients. It is a view of citizenship that closes down opportunities for popular involvement in the making of public knowledge by reinforcing the professional claims of experts. The journalists quoted above are right to feel uneasy, for there is, at almost every institutional level in contemporary society, scepticism towards the epistemological authority of expert elites. There is a growing feeling, as expressed by several of our focus group participants, that the news media should be \u201cinformative rather than authoritative\u201d; the job of journalists should be to\u201cgive the news as raw as it is, without putting their slant on it\u201d; and people should be given \u201csufficient information\u201d from which \u201cwe would be able to form opinions of our own.\u201d<\/p>\n\n\n\n
At stake here are two distinct conceptions of authority. The journalists we have quoted are resistant to the democratisation of news:the supremacy of the clickstream (according to which editors raise or lower the profile of stories according to the number of readers clicking on them online); the parity of popular culture with \u201cserious\u201dnews; the demands of some audience members for raw news rather than constructed narratives.<\/p>\n\n\n\n
<\/p>\n\n\n\n<\/figure>\n\n\n\nPassage 3<\/strong><\/h2>\n\n\n\nThis passage is adapted from Elsa Youngsteadt, \u201cDecoding aFlower\u2019s Message.\u201d \u00a92012 by Sigma Xi, The ScientificResearch Society.<\/em><\/p>\n\n\n\nTexas gourd vines unfurl their large, flared blossoms in the dim hours before sunrise. Until they close at noon, their yellow petals and mild, squashy aroma attract bees that gather nectar and shuttle pollen from flower to flower. But \u201cwhen you advertise [to pollinators], you advertise in an open communication network,\u201d says chemical ecologist Ian Baldwin of the Max Planck Institute for Chemical Ecology in Germany. \u201cYou attract not just the good guys, but you also attract the bad guys.\u201d Fora Texas gourd plant, striped cucumber beetles are among the very bad guys. They chew up pollen and petals, defecate in the flowers and transmit the dreaded bacterial wilt disease, an infection that can reduce an entire plant to a heap of collapsed tissue in mere days.<\/p>\n\n\n\n
In one recent study, Nina Theis and Lynn Adler took on the specific problem of the Texas gourd\u2014how to attract enough pollinators but not too many beetles. The Texas gourd vine\u2019s main pollinators are honey bees and specialized squash bees, which respond to its floral scent. The aroma includes 10 compounds, but the most abundant\u2014and the only one that lures squash bees into traps\u2014is 1,4-dimethoxybenzene.<\/p>\n\n\n\n
Intuition suggests that more of that aroma should be even more appealing to bees. \u201cWe have this assumption that a really fragrant flower is going to attract a lot of pollinators,\u201d says Theis, a chemical ecologist at Elms College in Chicopee,Massachusetts. But, she adds, that idea hasn\u2019t really been tested\u2014and extra scent could well call in more beetles, too. To find out, she and Adler planted 168 Texas gourd vines in an Iowa field and,throughout the August flowering season, made halfthe plants more fragrant by tucking dimethoxybenzene-treated swabs deep inside their flowers. Each treated flower emitted about 45 times more fragrance than a normal one; the other half of the plants got swabs without fragrance.<\/p>\n\n\n\n
The researchers also wanted to know whether extra beetles would impose a double cost by both damaging flowers and deterring bees, which might not bother to visit (and pollinate) a flower laden with other insects and their feces. So every half hour throughout the experiments, the team plucked all the beetles off of half the fragrance-enhanced flowers and half the control flowers, allowing bees to respond to the blossoms with and without interference bybeetles.<\/p>\n\n\n\n
Finally, they pollinated by hand half of the female flowers in each of the four combinations of fragrance and beetles. Hand-pollinated flowers should develop into fruits with the maximum number of seeds,providing a benchmark to see whether the fragrance-related activities of bees and beetles resulted in reduced pollination.\u201cIt was very labor intensive,\u201d says Theis.\u201cWe would be out there at four in the morning, three in the morning, to try and set up before these flowers open.\u201d As soon as they did, the team spent the next several hours walking from flower to flower,observing each for two-minute intervals \u201cand writing down everything we saw.\u201d<\/p>\n\n\n\n
What they saw was double the normal number of beetles on fragrance-enhanced blossoms.Pollinators, to their surprise, did not prefer the highly scented flowers. Squash bees were indifferent,and honey bees visited enhanced flowers less often than normal ones. Theis thinks the bees were repelled not by the fragrance itself, but by the abundance of beetles: The data showed that the more beetles on a flower, the less likely a honey bee was to visit it.<\/p>\n\n\n\n
That added up to less reproduction for fragrance-enhanced flowers. Gourds that developed from those blossoms weighed 9 percent less and had,on average, 20 fewer seeds than those from normal flowers. Hand pollination didn\u2019t rescue the seed set,indicating that beetles damaged flowers directly\u2014regardless of whether they also repelled pollinators. (Hand pollination did rescue fruit weight, a hard-to-interpret result that suggests that lost bee visits did somehow harm fruit development.)<\/p>\n\n\n\n
The new results provide a reason that Texas gourd plants never evolved to produce a stronger scent: \u201cIf you really ramp up the odor, you don\u2019t get more pollinators, but you can really get ripped apart by your enemies,\u201d says Rob Raguso, a chemical ecologist at Cornell University who was not involved in the Texas gourd study.<\/p>\n\n\n\n
Passage 4<\/strong><\/h2>\n\n\n\nPassage 1 is adapted from Abraham Lincoln, \u201cAddress to theYoung Men\u2019s Lyceum of Springfield, Illinois.\u201d Originallydelivered in 1838. Passage 2 is from Henry David Thoreau,\u201cResistance to Civil Government.\u201d Originally publishedin 1849.<\/em><\/p>\n\n\n\nPassage 1<\/strong><\/p>\n\n\n\nLet every American, every lover of liberty, every well wisher to his posterity, swear by the blood of the Revolution, never to violate in the least particular,the laws of the country; and never to tolerate their violation by others. As the patriots of seventy-six did to the support of the Declaration of Independence, so to the support of the Constitution and Laws, let every American pledge his life, his property, and his sacred honor;\u2014let every man remember that to violate the law, is to trample on the blood of his father, and to tear the character of his own, and his children\u2019s liberty. Let reverence for the laws, be breathed bye very American mother, to the lisping babe, that prattles on her lap\u2014let it be taught in schools, in seminaries, and in colleges;\u2014let it be written in Primers, spelling books, and in Almanacs;\u2014let it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice. And, in short,let it become the political religion of the nation;and let the old and the young, the rich and the poor,the grave and the gay, of all sexes and tongues, and colors and conditions, sacrifice unceasingly upon its altars….<\/p>\n\n\n\n
When I so pressingly urge a strict observance of all the laws, let me not be understood as saying there are no bad laws, nor that grievances may not arise,for the redress of which, no legal provisions have been made. I mean to say no such thing. But I do mean to say, that, although bad laws, if they exist,should be repealed as soon as possible, still while they continue in force, for the sake of example, they should be religiously observed. So also in unprovided cases. If such arise, let proper legal provisions be made for them with the least possible delay; but, till then, let them if not too intolerable, be borne with.<\/p>\n\n\n\n
There is no grievance that is a fit object of redress by mob law. In any case that arises, as for instance,the promulgation of abolitionism, one of two positions is necessarily true; that is, the thing is right within itself, and therefore deserves the protection of all law and all good citizens; or, it is wrong, and therefore proper to be prohibited by legal enactments; and in neither case, is the inter position of mob law, either necessary, justifiable, or excusable.<\/p>\n\n\n\n
Passage 2<\/strong><\/p>\n\n\n\nUnjust laws exist; shall we be content to obey them, or shall we endeavor to amend them, and obey them until we have succeeded, or shall we transgress them at once? Men generally, under such a government as this, think that they ought to wait until they have persuaded the majority to alter them.They think that, if they should resist, the remedy would be worse than the evil. But it is the fault of the government itself that the remedy is worse than the evil. It makes it worse. Why is it not more apt to anticipate and provide for reform? Why does it not cherish its wise minority? Why does it cry and resist before it is hurt?…<\/p>\n\n\n\n
If the injustice is part of the necessary friction of the machine of government, let it go, let it go;perchance it will wear smooth\u2014certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself,then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law. Let your life be a counter friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.<\/p>\n\n\n\n
As for adopting the ways which the State has provided for remedying the evil, I know not of such ways. They take too much time, and a man\u2019s life will be gone. I have other affairs to attend to. I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad. A man has not everything to do, but something; and because he cannot do everything, it is not necessary that he should do something wrong….<\/p>\n\n\n\n
I do not hesitate to say, that those who call themselves Abolitionists should at once effectually withdraw their support, both in person and property,from the government . . . and not wait till they constitute a majority of one, before they suffer the right to prevail through them. I think that it is enough if they have God on their side, without waiting for that other one. Moreover, any man more right than his neighbors constitutes a majority of one already.<\/p>\n\n\n\n
Passage 5<\/strong><\/h2>\n\n\n\nThis passage is adapted from Kevin Bullis, \u201cWhat Tech IsNext for the Solar Industry?\u201d \u00a92013 by MIT TechnologyReview.<\/em><\/p>\n\n\n\nSolar panel installations continue to grow quickly,but the solar panel manufacturing industry is in the doldrums because supply far exceeds demand. The poor market may be slowing innovation, but advances continue; judging by the mood this week at the IEEE Photovoltaics Specialists Conference in Tampa, Florida, people in the industry remain optimistic about its long-term prospects.<\/p>\n\n\n\n
The technology that\u2019s surprised almost everyone is conventional crystalline silicon. A few years ago,silicon solar panels cost $4 per watt, and Martin Green, professor at the University of New South Wales and one of the leading silicon solar panel researchers, declared that they\u2019d never go below $1 a watt. \u201cNow it\u2019s down to something like 50 cents a watt, and there\u2019s talk of hitting 36 cents per watt,\u201d he says.<\/p>\n\n\n\n
The U.S. Department of Energy has set a goal of reaching less than $1 a watt\u2014not just for the solar panels, but for complete, installed systems\u2014by 2020.Green thinks the solar industry will hit that target even sooner than that. If so, that would bring the direct cost of solar power to six cents per kilowatt-hour, which is cheaper than the average cost expected for power from new natural gas power plants.<\/p>\n\n\n\n
All parts of the silicon solar panel industry have been looking for ways to cut costs and improve the power output of solar panels, and that\u2019s led to steady cost reductions. Green points to something as mundane as the pastes used to screen-print some of the features on solar panels. Green\u2019s lab built a solar cell in the 1990s that set a record efficiency for silicon solar cells\u2014a record that stands to this day. To achieve that record, he had to use expensive lithography techniques to make fine wires for collecting current from the solar cell. But gradual improvements have made it possible to use screen printing to produce ever-finer lines. Recent research suggests that screen-printing techniques can produce lines as thin as 30 micrometers\u2014about the width of the lines Green used for his record solar cells, but at costs far lower than his lithography techniques.<\/p>\n\n\n\n
Meanwhile, researchers at the National Renewable Energy Laboratory have made flexible solar cells on anew type of glass from Corning called Willow Glass,which is thin and can be rolled up. The type of solar cell they made is the only current challenger to silicon in terms of large-scale production\u2014thin-film cadmium telluride. Flexible solar cells could lower the cost of installing solar cells, making solar powercheaper.<\/p>\n\n\n\n
One of Green\u2019s former students and colleagues, Jianhua Zhao, cofounder of solar panel manufacturer China Sunergy, announced this week that he is building a pilot manufacturing line for a two-sided solar cell that can absorb light from both the front and back. The basic idea, which isn\u2019t new, is that during some parts of the day, sunlight falls on the land between rows of solar panels in a solar power plant. That light reflects onto the back of the panels and could be harvested to increase the power output.This works particularly well when the solar panels are built on sand, which is highly reflective. Where a one-sided solar panel might generate 340 watts, a two-sided one might generate up to 400 watts. He expects the panels to generate 10 to 20 percent more electricity over the course of a year.<\/p>\n\n\n\n
Even longer-term, Green is betting on silicon,aiming to take advantage of the huge reductions in cost already seen with the technology. He hopes to greatly increase the efficiency of silicon solar panels by combining silicon with one or two other semiconductors, each selected to efficiently convert apart of the solar spectrum that silicon doesn\u2019t convert efficiently. Adding one semiconductor could boost efficiencies from the 20 to 25 percent range to around 40 percent. Adding another could make efficiencies as high as 50 percent feasible, which would cut in half the number of solar panels needed for a given installation.

His twelve daughters acted as a spur to his genius, and he looked with satisfaction in the mirror each morning at the face of a warrior going out to do battle. Nawab of course knew that he must proliferate his sources of revenue\u2014the salary he received from K. K. Harouni for tending the tube wells would not even begin to suffice. He set up a little one-room flour mill, run off a condemned electric motor\u2014condemned by him.He tried his hand at fish-farming in a little pond at the edge of his master\u2019s fields. He bought broken radios, fixed them, and resold them. He did not demur even when asked to fix watches, though that enterprise did spectacularly badly, and in fact earned him more kicks than kudos, for no watch he took apart ever kept time again.<\/p>\n\n\n\n
K. K. Harouni rarely went to his farms, but lived mostly in Lahore. Whenever the old man visited, Nawab would place himself night and day at the door leading from the servants\u2019 sitting area into the walled grove of ancient banyan trees where the old farmhouse stood. Grizzled, his peculiar aviator glasses bent and smudged, Nawab tended the household machinery, the air conditioners, water heaters, refrigerators, and water pumps, like an engineer tending the boilers on a foundering steamer in an Atlantic gale. By his superhuman efforts he almost managed to maintain K. K. Harouni in the same mechanical cocoon, cooled and bathed and lighted and fed, that the landowner enjoyed in Lahore.<\/p>\n\n\n\n
Harouni of course became familiar with this ubiquitous man, who not only accompanied him on his tours of inspection, but morning and night could be found standing on the master bed rewiring the light fixture or in the bathroom poking at the water heater. Finally, one evening at teatime, gauging the psychological moment, Nawab asked if he might say a word. The landowner, who was cheerfully filing his nails in front of a crackling rosewood fire, told him to go ahead.<\/p>\n\n\n\n
\u201cSir, as you know, your lands stretch from here to the Indus, and on these lands are fully seventeen tube wells, and to tend these seventeen tube wells there is but one man, me, your servant. In your service I have earned these gray hairs\u201d\u2014here he bowed his head to show the gray\u2014\u201cand now I cannot fulfill my duties as I should. Enough, sir, enough. I beg you, forgive me my weakness. Better a darkened house and proud hunger within than disgrace in the light of day.Release me, I ask you, I beg you.\u201d<\/p>\n\n\n\n
The old man, well accustomed to these sorts of speeches, though not usually this florid, filed away at his nails and waited for the breeze to stop.\u201cWhat\u2019s the matter, Nawabdin?\u201d<\/p>\n\n\n\n
\u201cMatter, sir? O what could be the matter in your service. I\u2019ve eaten your salt for all my years. But sir,on the bicycle now, with my old legs, and with the many injuries I\u2019ve received when heavy machinery fell on me\u2014I cannot any longer bicycle about like a bridegroom from farm to farm, as I could when I first had the good fortune to enter your employment.I beg you, sir, let me go.\u201d<\/p>\n\n\n\n
\u201cAnd what\u2019s the solution?\u201d asked Harouni, seeingthat they had come to the crux. He didn\u2019t particularly care one way or the other, except that it touched on his comfort\u2014a matter of great interest to him.<\/p>\n\n\n\n
\u201cWell, sir, if I had a motorcycle, then I could somehow limp along, at least until I train up some younger man.\u201d<\/p>\n\n\n\n
The crops that year had been good, Harouni feltexpansive in front of the fire, and so, much to the disgust of the farm managers, Nawab received a brand-new motorcycle, a Honda 70. He even managed to extract an allowance for gasoline.<\/p>\n\n\n\n
The motorcycle increased his status, gave him weight, so that people began calling him \u201cUncle,\u201d and asking his opinion on world affairs, about which he knew absolutely nothing. He could now range further, doing a much wider business. Best of all,now he could spend every night with his wife, who had begged to live not on the farm but near her family in Firoza, where also they could educate at least the two eldest daughters. A long straight road ran from the canal head works near Firoza all the way to the Indus, through the heart of the K. K. Harouni lands. Nawab would fly down this road on his new machine, with bags and cloths hanging from every knob and brace, so that the bike, when he hit a bump,seemed to be flapping numerous small vestigial wings; and with his grinning face, as he rolled up to whichever tube well needed servicing, with his ears almost blown off, he shone with the speed of his arrival.<\/p>\n\n\n\n
PASSAGE 2<\/strong><\/h3>\n\n\n\nThis passage is adapted from Stephen Coleman, ScottAnthony, and David E. Morrison, \u201cPublic Trust in the News.\u201d\u00a92009 by Stephen Coleman.<\/em><\/p>\n\n\n\nThe news is a form of public knowledge.Unlike personal or private knowledge (such as of one\u2019s friends and family; the conduct of a private hobby; a secret liaison), public know ledge increases in value as it is shared by more people. The date of an election and the claims of rival candidates;the causes and consequences of an environmental disaster; a debate about how to frame a particular law; the latest reports from a war zone\u2014these are all examples of public knowledge that people are generally expected to know in order to be considered informed citizens. Thus, in contrast to personal or private knowledge, which is generally left to individuals to pursue or ignore, public knowledge is promoted even to those who might not think it matters to them. In short, the circulation of public knowledge, including the news, is generally regarded as a public good which cannot be solely demand-driven.<\/p>\n\n\n\n
The production, circulation, and reception of public knowledge is a complex process. It is generally accepted that public knowledge should be authoritative, but there is not always common agreement about what the public needs to know, who is best placed to relate and explain it, and how authoritative reputations should be determined and evaluated. Historically, newspapers such as The Times<\/em> and broadcasters such as the BBC were widely regarded as the trusted shapers of authoritative agendas and conventional wisdom. They embodied the Oxford English Dictionary\u2019s<\/em> definition of authority as the \u201cpower over, or title to influence, the opinions of others.\u201d As part of the general process of the transformation of authority whereby there has been a reluctance to uncritically accept traditional sources of public knowledge, the demand has been for all authority to make explicit the frames of value which determine their decisions. Centres of news production, as our focus groups show, have not been exempt from this process. Not surprisingly perhaps some news journalists feel uneasy about this renegotiation of their authority:<\/p>\n\n\n\nEditors are increasingly casting a glance at the\u201cmost read\u201d lists on their own and other websites to work out which stories matter to readers and viewers. And now the audience\u2014which used to know its place\u2014is being asked to act as a kind of journalistic ombudsman, ruling on our credibility (broadcast journalist, 2008).<\/p>\n\n\n\n
The result of democratising access to TV news could be political disengagement by the majority and a dumbing down through a popularity contest of stories (online news editor, 2007).<\/p>\n\n\n\n
Despite the rhetorical bluster of these statements,they amount to more than straightforward professional defensiveness. In their reference to an audience \u201cwhich used to know its place\u201d and conflation between democratisation and \u201cdumbing down,\u201d they are seeking to argue for a particular mode of public knowledge: one which is shaped by experts, immune from populist pressures; and disseminated to attentive, but mainly passive recipients. It is a view of citizenship that closes down opportunities for popular involvement in the making of public knowledge by reinforcing the professional claims of experts. The journalists quoted above are right to feel uneasy, for there is, at almost every institutional level in contemporary society, scepticism towards the epistemological authority of expert elites. There is a growing feeling, as expressed by several of our focus group participants, that the news media should be \u201cinformative rather than authoritative\u201d; the job of journalists should be to\u201cgive the news as raw as it is, without putting their slant on it\u201d; and people should be given \u201csufficient information\u201d from which \u201cwe would be able to form opinions of our own.\u201d<\/p>\n\n\n\n
At stake here are two distinct conceptions of authority. The journalists we have quoted are resistant to the democratisation of news:the supremacy of the clickstream (according to which editors raise or lower the profile of stories according to the number of readers clicking on them online); the parity of popular culture with \u201cserious\u201dnews; the demands of some audience members for raw news rather than constructed narratives.<\/p>\n\n\n\n
<\/p>\n\n\n\n<\/figure>\n\n\n\nPassage 3<\/strong><\/h2>\n\n\n\nThis passage is adapted from Elsa Youngsteadt, \u201cDecoding aFlower\u2019s Message.\u201d \u00a92012 by Sigma Xi, The ScientificResearch Society.<\/em><\/p>\n\n\n\nTexas gourd vines unfurl their large, flared blossoms in the dim hours before sunrise. Until they close at noon, their yellow petals and mild, squashy aroma attract bees that gather nectar and shuttle pollen from flower to flower. But \u201cwhen you advertise [to pollinators], you advertise in an open communication network,\u201d says chemical ecologist Ian Baldwin of the Max Planck Institute for Chemical Ecology in Germany. \u201cYou attract not just the good guys, but you also attract the bad guys.\u201d Fora Texas gourd plant, striped cucumber beetles are among the very bad guys. They chew up pollen and petals, defecate in the flowers and transmit the dreaded bacterial wilt disease, an infection that can reduce an entire plant to a heap of collapsed tissue in mere days.<\/p>\n\n\n\n
In one recent study, Nina Theis and Lynn Adler took on the specific problem of the Texas gourd\u2014how to attract enough pollinators but not too many beetles. The Texas gourd vine\u2019s main pollinators are honey bees and specialized squash bees, which respond to its floral scent. The aroma includes 10 compounds, but the most abundant\u2014and the only one that lures squash bees into traps\u2014is 1,4-dimethoxybenzene.<\/p>\n\n\n\n
Intuition suggests that more of that aroma should be even more appealing to bees. \u201cWe have this assumption that a really fragrant flower is going to attract a lot of pollinators,\u201d says Theis, a chemical ecologist at Elms College in Chicopee,Massachusetts. But, she adds, that idea hasn\u2019t really been tested\u2014and extra scent could well call in more beetles, too. To find out, she and Adler planted 168 Texas gourd vines in an Iowa field and,throughout the August flowering season, made halfthe plants more fragrant by tucking dimethoxybenzene-treated swabs deep inside their flowers. Each treated flower emitted about 45 times more fragrance than a normal one; the other half of the plants got swabs without fragrance.<\/p>\n\n\n\n
The researchers also wanted to know whether extra beetles would impose a double cost by both damaging flowers and deterring bees, which might not bother to visit (and pollinate) a flower laden with other insects and their feces. So every half hour throughout the experiments, the team plucked all the beetles off of half the fragrance-enhanced flowers and half the control flowers, allowing bees to respond to the blossoms with and without interference bybeetles.<\/p>\n\n\n\n
Finally, they pollinated by hand half of the female flowers in each of the four combinations of fragrance and beetles. Hand-pollinated flowers should develop into fruits with the maximum number of seeds,providing a benchmark to see whether the fragrance-related activities of bees and beetles resulted in reduced pollination.\u201cIt was very labor intensive,\u201d says Theis.\u201cWe would be out there at four in the morning, three in the morning, to try and set up before these flowers open.\u201d As soon as they did, the team spent the next several hours walking from flower to flower,observing each for two-minute intervals \u201cand writing down everything we saw.\u201d<\/p>\n\n\n\n
What they saw was double the normal number of beetles on fragrance-enhanced blossoms.Pollinators, to their surprise, did not prefer the highly scented flowers. Squash bees were indifferent,and honey bees visited enhanced flowers less often than normal ones. Theis thinks the bees were repelled not by the fragrance itself, but by the abundance of beetles: The data showed that the more beetles on a flower, the less likely a honey bee was to visit it.<\/p>\n\n\n\n
That added up to less reproduction for fragrance-enhanced flowers. Gourds that developed from those blossoms weighed 9 percent less and had,on average, 20 fewer seeds than those from normal flowers. Hand pollination didn\u2019t rescue the seed set,indicating that beetles damaged flowers directly\u2014regardless of whether they also repelled pollinators. (Hand pollination did rescue fruit weight, a hard-to-interpret result that suggests that lost bee visits did somehow harm fruit development.)<\/p>\n\n\n\n
The new results provide a reason that Texas gourd plants never evolved to produce a stronger scent: \u201cIf you really ramp up the odor, you don\u2019t get more pollinators, but you can really get ripped apart by your enemies,\u201d says Rob Raguso, a chemical ecologist at Cornell University who was not involved in the Texas gourd study.<\/p>\n\n\n\n
Passage 4<\/strong><\/h2>\n\n\n\nPassage 1 is adapted from Abraham Lincoln, \u201cAddress to theYoung Men\u2019s Lyceum of Springfield, Illinois.\u201d Originallydelivered in 1838. Passage 2 is from Henry David Thoreau,\u201cResistance to Civil Government.\u201d Originally publishedin 1849.<\/em><\/p>\n\n\n\nPassage 1<\/strong><\/p>\n\n\n\nLet every American, every lover of liberty, every well wisher to his posterity, swear by the blood of the Revolution, never to violate in the least particular,the laws of the country; and never to tolerate their violation by others. As the patriots of seventy-six did to the support of the Declaration of Independence, so to the support of the Constitution and Laws, let every American pledge his life, his property, and his sacred honor;\u2014let every man remember that to violate the law, is to trample on the blood of his father, and to tear the character of his own, and his children\u2019s liberty. Let reverence for the laws, be breathed bye very American mother, to the lisping babe, that prattles on her lap\u2014let it be taught in schools, in seminaries, and in colleges;\u2014let it be written in Primers, spelling books, and in Almanacs;\u2014let it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice. And, in short,let it become the political religion of the nation;and let the old and the young, the rich and the poor,the grave and the gay, of all sexes and tongues, and colors and conditions, sacrifice unceasingly upon its altars….<\/p>\n\n\n\n
When I so pressingly urge a strict observance of all the laws, let me not be understood as saying there are no bad laws, nor that grievances may not arise,for the redress of which, no legal provisions have been made. I mean to say no such thing. But I do mean to say, that, although bad laws, if they exist,should be repealed as soon as possible, still while they continue in force, for the sake of example, they should be religiously observed. So also in unprovided cases. If such arise, let proper legal provisions be made for them with the least possible delay; but, till then, let them if not too intolerable, be borne with.<\/p>\n\n\n\n
There is no grievance that is a fit object of redress by mob law. In any case that arises, as for instance,the promulgation of abolitionism, one of two positions is necessarily true; that is, the thing is right within itself, and therefore deserves the protection of all law and all good citizens; or, it is wrong, and therefore proper to be prohibited by legal enactments; and in neither case, is the inter position of mob law, either necessary, justifiable, or excusable.<\/p>\n\n\n\n
Passage 2<\/strong><\/p>\n\n\n\nUnjust laws exist; shall we be content to obey them, or shall we endeavor to amend them, and obey them until we have succeeded, or shall we transgress them at once? Men generally, under such a government as this, think that they ought to wait until they have persuaded the majority to alter them.They think that, if they should resist, the remedy would be worse than the evil. But it is the fault of the government itself that the remedy is worse than the evil. It makes it worse. Why is it not more apt to anticipate and provide for reform? Why does it not cherish its wise minority? Why does it cry and resist before it is hurt?…<\/p>\n\n\n\n
If the injustice is part of the necessary friction of the machine of government, let it go, let it go;perchance it will wear smooth\u2014certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself,then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law. Let your life be a counter friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.<\/p>\n\n\n\n
As for adopting the ways which the State has provided for remedying the evil, I know not of such ways. They take too much time, and a man\u2019s life will be gone. I have other affairs to attend to. I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad. A man has not everything to do, but something; and because he cannot do everything, it is not necessary that he should do something wrong….<\/p>\n\n\n\n
I do not hesitate to say, that those who call themselves Abolitionists should at once effectually withdraw their support, both in person and property,from the government . . . and not wait till they constitute a majority of one, before they suffer the right to prevail through them. I think that it is enough if they have God on their side, without waiting for that other one. Moreover, any man more right than his neighbors constitutes a majority of one already.<\/p>\n\n\n\n
Passage 5<\/strong><\/h2>\n\n\n\nThis passage is adapted from Kevin Bullis, \u201cWhat Tech IsNext for the Solar Industry?\u201d \u00a92013 by MIT TechnologyReview.<\/em><\/p>\n\n\n\nSolar panel installations continue to grow quickly,but the solar panel manufacturing industry is in the doldrums because supply far exceeds demand. The poor market may be slowing innovation, but advances continue; judging by the mood this week at the IEEE Photovoltaics Specialists Conference in Tampa, Florida, people in the industry remain optimistic about its long-term prospects.<\/p>\n\n\n\n
The technology that\u2019s surprised almost everyone is conventional crystalline silicon. A few years ago,silicon solar panels cost $4 per watt, and Martin Green, professor at the University of New South Wales and one of the leading silicon solar panel researchers, declared that they\u2019d never go below $1 a watt. \u201cNow it\u2019s down to something like 50 cents a watt, and there\u2019s talk of hitting 36 cents per watt,\u201d he says.<\/p>\n\n\n\n
The U.S. Department of Energy has set a goal of reaching less than $1 a watt\u2014not just for the solar panels, but for complete, installed systems\u2014by 2020.Green thinks the solar industry will hit that target even sooner than that. If so, that would bring the direct cost of solar power to six cents per kilowatt-hour, which is cheaper than the average cost expected for power from new natural gas power plants.<\/p>\n\n\n\n
All parts of the silicon solar panel industry have been looking for ways to cut costs and improve the power output of solar panels, and that\u2019s led to steady cost reductions. Green points to something as mundane as the pastes used to screen-print some of the features on solar panels. Green\u2019s lab built a solar cell in the 1990s that set a record efficiency for silicon solar cells\u2014a record that stands to this day. To achieve that record, he had to use expensive lithography techniques to make fine wires for collecting current from the solar cell. But gradual improvements have made it possible to use screen printing to produce ever-finer lines. Recent research suggests that screen-printing techniques can produce lines as thin as 30 micrometers\u2014about the width of the lines Green used for his record solar cells, but at costs far lower than his lithography techniques.<\/p>\n\n\n\n
Meanwhile, researchers at the National Renewable Energy Laboratory have made flexible solar cells on anew type of glass from Corning called Willow Glass,which is thin and can be rolled up. The type of solar cell they made is the only current challenger to silicon in terms of large-scale production\u2014thin-film cadmium telluride. Flexible solar cells could lower the cost of installing solar cells, making solar powercheaper.<\/p>\n\n\n\n
One of Green\u2019s former students and colleagues, Jianhua Zhao, cofounder of solar panel manufacturer China Sunergy, announced this week that he is building a pilot manufacturing line for a two-sided solar cell that can absorb light from both the front and back. The basic idea, which isn\u2019t new, is that during some parts of the day, sunlight falls on the land between rows of solar panels in a solar power plant. That light reflects onto the back of the panels and could be harvested to increase the power output.This works particularly well when the solar panels are built on sand, which is highly reflective. Where a one-sided solar panel might generate 340 watts, a two-sided one might generate up to 400 watts. He expects the panels to generate 10 to 20 percent more electricity over the course of a year.<\/p>\n\n\n\n
Even longer-term, Green is betting on silicon,aiming to take advantage of the huge reductions in cost already seen with the technology. He hopes to greatly increase the efficiency of silicon solar panels by combining silicon with one or two other semiconductors, each selected to efficiently convert apart of the solar spectrum that silicon doesn\u2019t convert efficiently. Adding one semiconductor could boost efficiencies from the 20 to 25 percent range to around 40 percent. Adding another could make efficiencies as high as 50 percent feasible, which would cut in half the number of solar panels needed for a given installation. The challenge is to produce good connections between these semiconductors,something made challenging by the arrangement of silicon atoms in crystalline silicon.<\/p>\n\n\n\n<\/figure>\n\n\n\n

This passage is adapted from Daniyal Mueenuddin, \u201cNawabdin Electrician.\u201d \u00a92009 by Daniyal Mueenuddin.<\/em><\/p>\n\n\n\n Another man might have thrown up his hands\u2014but not Nawabdin. His twelve daughters acted as a spur to his genius, and he looked with satisfaction in the mirror each morning at the face of a warrior going out to do battle. Nawab of course knew that he must proliferate his sources of revenue\u2014the salary he received from K. K. Harouni for tending the tube wells would not even begin to suffice. He set up a little one-room flour mill, run off a condemned electric motor\u2014condemned by him.He tried his hand at fish-farming in a little pond at the edge of his master\u2019s fields. He bought broken radios, fixed them, and resold them. He did not demur even when asked to fix watches, though that enterprise did spectacularly badly, and in fact earned him more kicks than kudos, for no watch he took apart ever kept time again.<\/p>\n\n\n\n K. K. Harouni rarely went to his farms, but lived mostly in Lahore. Whenever the old man visited, Nawab would place himself night and day at the door leading from the servants\u2019 sitting area into the walled grove of ancient banyan trees where the old farmhouse stood. Grizzled, his peculiar aviator glasses bent and smudged, Nawab tended the household machinery, the air conditioners, water heaters, refrigerators, and water pumps, like an engineer tending the boilers on a foundering steamer in an Atlantic gale. By his superhuman efforts he almost managed to maintain K. K. Harouni in the same mechanical cocoon, cooled and bathed and lighted and fed, that the landowner enjoyed in Lahore.<\/p>\n\n\n\n Harouni of course became familiar with this ubiquitous man, who not only accompanied him on his tours of inspection, but morning and night could be found standing on the master bed rewiring the light fixture or in the bathroom poking at the water heater. Finally, one evening at teatime, gauging the psychological moment, Nawab asked if he might say a word. The landowner, who was cheerfully filing his nails in front of a crackling rosewood fire, told him to go ahead.<\/p>\n\n\n\n \u201cSir, as you know, your lands stretch from here to the Indus, and on these lands are fully seventeen tube wells, and to tend these seventeen tube wells there is but one man, me, your servant. In your service I have earned these gray hairs\u201d\u2014here he bowed his head to show the gray\u2014\u201cand now I cannot fulfill my duties as I should. Enough, sir, enough. I beg you, forgive me my weakness. Better a darkened house and proud hunger within than disgrace in the light of day.Release me, I ask you, I beg you.\u201d<\/p>\n\n\n\n The old man, well accustomed to these sorts of speeches, though not usually this florid, filed away at his nails and waited for the breeze to stop.\u201cWhat\u2019s the matter, Nawabdin?\u201d<\/p>\n\n\n\n \u201cMatter, sir? O what could be the matter in your service. I\u2019ve eaten your salt for all my years. But sir,on the bicycle now, with my old legs, and with the many injuries I\u2019ve received when heavy machinery fell on me\u2014I cannot any longer bicycle about like a bridegroom from farm to farm, as I could when I first had the good fortune to enter your employment.I beg you, sir, let me go.\u201d<\/p>\n\n\n\n \u201cAnd what\u2019s the solution?\u201d asked Harouni, seeingthat they had come to the crux. He didn\u2019t particularly care one way or the other, except that it touched on his comfort\u2014a matter of great interest to him.<\/p>\n\n\n\n \u201cWell, sir, if I had a motorcycle, then I could somehow limp along, at least until I train up some younger man.\u201d<\/p>\n\n\n\n The crops that year had been good, Harouni feltexpansive in front of the fire, and so, much to the disgust of the farm managers, Nawab received a brand-new motorcycle, a Honda 70. He even managed to extract an allowance for gasoline.<\/p>\n\n\n\n The motorcycle increased his status, gave him weight, so that people began calling him \u201cUncle,\u201d and asking his opinion on world affairs, about which he knew absolutely nothing. He could now range further, doing a much wider business. Best of all,now he could spend every night with his wife, who had begged to live not on the farm but near her family in Firoza, where also they could educate at least the two eldest daughters. A long straight road ran from the canal head works near Firoza all the way to the Indus, through the heart of the K. K. Harouni lands. Nawab would fly down this road on his new machine, with bags and cloths hanging from every knob and brace, so that the bike, when he hit a bump,seemed to be flapping numerous small vestigial wings; and with his grinning face, as he rolled up to whichever tube well needed servicing, with his ears almost blown off, he shone with the speed of his arrival.<\/p>\n\n\n\n This passage is adapted from Stephen Coleman, ScottAnthony, and David E. Morrison, \u201cPublic Trust in the News.\u201d\u00a92009 by Stephen Coleman.<\/em><\/p>\n\n\n\n The news is a form of public knowledge.Unlike personal or private knowledge (such as of one\u2019s friends and family; the conduct of a private hobby; a secret liaison), public know ledge increases in value as it is shared by more people. The date of an election and the claims of rival candidates;the causes and consequences of an environmental disaster; a debate about how to frame a particular law; the latest reports from a war zone\u2014these are all examples of public knowledge that people are generally expected to know in order to be considered informed citizens. Thus, in contrast to personal or private knowledge, which is generally left to individuals to pursue or ignore, public knowledge is promoted even to those who might not think it matters to them. In short, the circulation of public knowledge, including the news, is generally regarded as a public good which cannot be solely demand-driven.<\/p>\n\n\n\n The production, circulation, and reception of public knowledge is a complex process. It is generally accepted that public knowledge should be authoritative, but there is not always common agreement about what the public needs to know, who is best placed to relate and explain it, and how authoritative reputations should be determined and evaluated. Historically, newspapers such as The Times<\/em> and broadcasters such as the BBC were widely regarded as the trusted shapers of authoritative agendas and conventional wisdom. They embodied the Oxford English Dictionary\u2019s<\/em> definition of authority as the \u201cpower over, or title to influence, the opinions of others.\u201d As part of the general process of the transformation of authority whereby there has been a reluctance to uncritically accept traditional sources of public knowledge, the demand has been for all authority to make explicit the frames of value which determine their decisions. Centres of news production, as our focus groups show, have not been exempt from this process. Not surprisingly perhaps some news journalists feel uneasy about this renegotiation of their authority:<\/p>\n\n\n\n Editors are increasingly casting a glance at the\u201cmost read\u201d lists on their own and other websites to work out which stories matter to readers and viewers. And now the audience\u2014which used to know its place\u2014is being asked to act as a kind of journalistic ombudsman, ruling on our credibility (broadcast journalist, 2008).<\/p>\n\n\n\n The result of democratising access to TV news could be political disengagement by the majority and a dumbing down through a popularity contest of stories (online news editor, 2007).<\/p>\n\n\n\n Despite the rhetorical bluster of these statements,they amount to more than straightforward professional defensiveness. In their reference to an audience \u201cwhich used to know its place\u201d and conflation between democratisation and \u201cdumbing down,\u201d they are seeking to argue for a particular mode of public knowledge: one which is shaped by experts, immune from populist pressures; and disseminated to attentive, but mainly passive recipients. It is a view of citizenship that closes down opportunities for popular involvement in the making of public knowledge by reinforcing the professional claims of experts. The journalists quoted above are right to feel uneasy, for there is, at almost every institutional level in contemporary society, scepticism towards the epistemological authority of expert elites. There is a growing feeling, as expressed by several of our focus group participants, that the news media should be \u201cinformative rather than authoritative\u201d; the job of journalists should be to\u201cgive the news as raw as it is, without putting their slant on it\u201d; and people should be given \u201csufficient information\u201d from which \u201cwe would be able to form opinions of our own.\u201d<\/p>\n\n\n\n At stake here are two distinct conceptions of authority. The journalists we have quoted are resistant to the democratisation of news:the supremacy of the clickstream (according to which editors raise or lower the profile of stories according to the number of readers clicking on them online); the parity of popular culture with \u201cserious\u201dnews; the demands of some audience members for raw news rather than constructed narratives.<\/p>\n\n\n\n This passage is adapted from Elsa Youngsteadt, \u201cDecoding aFlower\u2019s Message.\u201d \u00a92012 by Sigma Xi, The ScientificResearch Society.<\/em><\/p>\n\n\n\n Texas gourd vines unfurl their large, flared blossoms in the dim hours before sunrise. Until they close at noon, their yellow petals and mild, squashy aroma attract bees that gather nectar and shuttle pollen from flower to flower. But \u201cwhen you advertise [to pollinators], you advertise in an open communication network,\u201d says chemical ecologist Ian Baldwin of the Max Planck Institute for Chemical Ecology in Germany. \u201cYou attract not just the good guys, but you also attract the bad guys.\u201d Fora Texas gourd plant, striped cucumber beetles are among the very bad guys. They chew up pollen and petals, defecate in the flowers and transmit the dreaded bacterial wilt disease, an infection that can reduce an entire plant to a heap of collapsed tissue in mere days.<\/p>\n\n\n\n In one recent study, Nina Theis and Lynn Adler took on the specific problem of the Texas gourd\u2014how to attract enough pollinators but not too many beetles. The Texas gourd vine\u2019s main pollinators are honey bees and specialized squash bees, which respond to its floral scent. The aroma includes 10 compounds, but the most abundant\u2014and the only one that lures squash bees into traps\u2014is 1,4-dimethoxybenzene.<\/p>\n\n\n\n Intuition suggests that more of that aroma should be even more appealing to bees. \u201cWe have this assumption that a really fragrant flower is going to attract a lot of pollinators,\u201d says Theis, a chemical ecologist at Elms College in Chicopee,Massachusetts. But, she adds, that idea hasn\u2019t really been tested\u2014and extra scent could well call in more beetles, too. To find out, she and Adler planted 168 Texas gourd vines in an Iowa field and,throughout the August flowering season, made halfthe plants more fragrant by tucking dimethoxybenzene-treated swabs deep inside their flowers. Each treated flower emitted about 45 times more fragrance than a normal one; the other half of the plants got swabs without fragrance.<\/p>\n\n\n\n The researchers also wanted to know whether extra beetles would impose a double cost by both damaging flowers and deterring bees, which might not bother to visit (and pollinate) a flower laden with other insects and their feces. So every half hour throughout the experiments, the team plucked all the beetles off of half the fragrance-enhanced flowers and half the control flowers, allowing bees to respond to the blossoms with and without interference bybeetles.<\/p>\n\n\n\n Finally, they pollinated by hand half of the female flowers in each of the four combinations of fragrance and beetles. Hand-pollinated flowers should develop into fruits with the maximum number of seeds,providing a benchmark to see whether the fragrance-related activities of bees and beetles resulted in reduced pollination.\u201cIt was very labor intensive,\u201d says Theis.\u201cWe would be out there at four in the morning, three in the morning, to try and set up before these flowers open.\u201d As soon as they did, the team spent the next several hours walking from flower to flower,observing each for two-minute intervals \u201cand writing down everything we saw.\u201d<\/p>\n\n\n\n What they saw was double the normal number of beetles on fragrance-enhanced blossoms.Pollinators, to their surprise, did not prefer the highly scented flowers. Squash bees were indifferent,and honey bees visited enhanced flowers less often than normal ones. Theis thinks the bees were repelled not by the fragrance itself, but by the abundance of beetles: The data showed that the more beetles on a flower, the less likely a honey bee was to visit it.<\/p>\n\n\n\n That added up to less reproduction for fragrance-enhanced flowers. Gourds that developed from those blossoms weighed 9 percent less and had,on average, 20 fewer seeds than those from normal flowers. Hand pollination didn\u2019t rescue the seed set,indicating that beetles damaged flowers directly\u2014regardless of whether they also repelled pollinators. (Hand pollination did rescue fruit weight, a hard-to-interpret result that suggests that lost bee visits did somehow harm fruit development.)<\/p>\n\n\n\n The new results provide a reason that Texas gourd plants never evolved to produce a stronger scent: \u201cIf you really ramp up the odor, you don\u2019t get more pollinators, but you can really get ripped apart by your enemies,\u201d says Rob Raguso, a chemical ecologist at Cornell University who was not involved in the Texas gourd study.<\/p>\n\n\n\n Passage 1 is adapted from Abraham Lincoln, \u201cAddress to theYoung Men\u2019s Lyceum of Springfield, Illinois.\u201d Originallydelivered in 1838. Passage 2 is from Henry David Thoreau,\u201cResistance to Civil Government.\u201d Originally publishedin 1849.<\/em><\/p>\n\n\n\n Passage 1<\/strong><\/p>\n\n\n\n Let every American, every lover of liberty, every well wisher to his posterity, swear by the blood of the Revolution, never to violate in the least particular,the laws of the country; and never to tolerate their violation by others. As the patriots of seventy-six did to the support of the Declaration of Independence, so to the support of the Constitution and Laws, let every American pledge his life, his property, and his sacred honor;\u2014let every man remember that to violate the law, is to trample on the blood of his father, and to tear the character of his own, and his children\u2019s liberty. Let reverence for the laws, be breathed bye very American mother, to the lisping babe, that prattles on her lap\u2014let it be taught in schools, in seminaries, and in colleges;\u2014let it be written in Primers, spelling books, and in Almanacs;\u2014let it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice. And, in short,let it become the political religion of the nation;and let the old and the young, the rich and the poor,the grave and the gay, of all sexes and tongues, and colors and conditions, sacrifice unceasingly upon its altars….<\/p>\n\n\n\n When I so pressingly urge a strict observance of all the laws, let me not be understood as saying there are no bad laws, nor that grievances may not arise,for the redress of which, no legal provisions have been made. I mean to say no such thing. But I do mean to say, that, although bad laws, if they exist,should be repealed as soon as possible, still while they continue in force, for the sake of example, they should be religiously observed. So also in unprovided cases. If such arise, let proper legal provisions be made for them with the least possible delay; but, till then, let them if not too intolerable, be borne with.<\/p>\n\n\n\n There is no grievance that is a fit object of redress by mob law. In any case that arises, as for instance,the promulgation of abolitionism, one of two positions is necessarily true; that is, the thing is right within itself, and therefore deserves the protection of all law and all good citizens; or, it is wrong, and therefore proper to be prohibited by legal enactments; and in neither case, is the inter position of mob law, either necessary, justifiable, or excusable.<\/p>\n\n\n\n Passage 2<\/strong><\/p>\n\n\n\n Unjust laws exist; shall we be content to obey them, or shall we endeavor to amend them, and obey them until we have succeeded, or shall we transgress them at once? Men generally, under such a government as this, think that they ought to wait until they have persuaded the majority to alter them.They think that, if they should resist, the remedy would be worse than the evil. But it is the fault of the government itself that the remedy is worse than the evil. It makes it worse. Why is it not more apt to anticipate and provide for reform? Why does it not cherish its wise minority? Why does it cry and resist before it is hurt?…<\/p>\n\n\n\n If the injustice is part of the necessary friction of the machine of government, let it go, let it go;perchance it will wear smooth\u2014certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself,then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law. Let your life be a counter friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.<\/p>\n\n\n\n As for adopting the ways which the State has provided for remedying the evil, I know not of such ways. They take too much time, and a man\u2019s life will be gone. I have other affairs to attend to. I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad. A man has not everything to do, but something; and because he cannot do everything, it is not necessary that he should do something wrong….<\/p>\n\n\n\n I do not hesitate to say, that those who call themselves Abolitionists should at once effectually withdraw their support, both in person and property,from the government . . . and not wait till they constitute a majority of one, before they suffer the right to prevail through them. I think that it is enough if they have God on their side, without waiting for that other one. Moreover, any man more right than his neighbors constitutes a majority of one already.<\/p>\n\n\n\n This passage is adapted from Kevin Bullis, \u201cWhat Tech IsNext for the Solar Industry?\u201d \u00a92013 by MIT TechnologyReview.<\/em><\/p>\n\n\n\n Solar panel installations continue to grow quickly,but the solar panel manufacturing industry is in the doldrums because supply far exceeds demand. The poor market may be slowing innovation, but advances continue; judging by the mood this week at the IEEE Photovoltaics Specialists Conference in Tampa, Florida, people in the industry remain optimistic about its long-term prospects.<\/p>\n\n\n\n The technology that\u2019s surprised almost everyone is conventional crystalline silicon. A few years ago,silicon solar panels cost $4 per watt, and Martin Green, professor at the University of New South Wales and one of the leading silicon solar panel researchers, declared that they\u2019d never go below $1 a watt. \u201cNow it\u2019s down to something like 50 cents a watt, and there\u2019s talk of hitting 36 cents per watt,\u201d he says.<\/p>\n\n\n\n The U.S. Department of Energy has set a goal of reaching less than $1 a watt\u2014not just for the solar panels, but for complete, installed systems\u2014by 2020.Green thinks the solar industry will hit that target even sooner than that. If so, that would bring the direct cost of solar power to six cents per kilowatt-hour, which is cheaper than the average cost expected for power from new natural gas power plants.<\/p>\n\n\n\n All parts of the silicon solar panel industry have been looking for ways to cut costs and improve the power output of solar panels, and that\u2019s led to steady cost reductions. Green points to something as mundane as the pastes used to screen-print some of the features on solar panels. Green\u2019s lab built a solar cell in the 1990s that set a record efficiency for silicon solar cells\u2014a record that stands to this day. To achieve that record, he had to use expensive lithography techniques to make fine wires for collecting current from the solar cell. But gradual improvements have made it possible to use screen printing to produce ever-finer lines. Recent research suggests that screen-printing techniques can produce lines as thin as 30 micrometers\u2014about the width of the lines Green used for his record solar cells, but at costs far lower than his lithography techniques.<\/p>\n\n\n\n Meanwhile, researchers at the National Renewable Energy Laboratory have made flexible solar cells on anew type of glass from Corning called Willow Glass,which is thin and can be rolled up. The type of solar cell they made is the only current challenger to silicon in terms of large-scale production\u2014thin-film cadmium telluride. Flexible solar cells could lower the cost of installing solar cells, making solar powercheaper.<\/p>\n\n\n\n One of Green\u2019s former students and colleagues, Jianhua Zhao, cofounder of solar panel manufacturer China Sunergy, announced this week that he is building a pilot manufacturing line for a two-sided solar cell that can absorb light from both the front and back. The basic idea, which isn\u2019t new, is that during some parts of the day, sunlight falls on the land between rows of solar panels in a solar power plant. That light reflects onto the back of the panels and could be harvested to increase the power output.This works particularly well when the solar panels are built on sand, which is highly reflective. Where a one-sided solar panel might generate 340 watts, a two-sided one might generate up to 400 watts. He expects the panels to generate 10 to 20 percent more electricity over the course of a year.<\/p>\n\n\n\n Even longer-term, Green is betting on silicon,aiming to take advantage of the huge reductions in cost already seen with the technology. He hopes to greatly increase the efficiency of silicon solar panels by combining silicon with one or two other semiconductors, each selected to efficiently convert apart of the solar spectrum that silicon doesn\u2019t convert efficiently. Adding one semiconductor could boost efficiencies from the 20 to 25 percent range to around 40 percent. Adding another could make efficiencies as high as 50 percent feasible, which would cut in half the number of solar panels needed for a given installation. The challenge is to produce good connections between these semiconductors,something made challenging by the arrangement of silicon atoms in crystalline silicon.<\/p>\n\n\n\n Ivy-Way \u5b66\u751f\u5728\u4e0a\u8bfe\u7684\u8fc7\u7a0b\u5c31\u4f1a\u505a\u52302016\u5e745\u6708\u4ee5\u53ca\u5176\u4ed6\u7684\u5b98\u65b9\u5386\u5e74\u8003\u9898\u3002\u9664\u6b64\u4e4b\u5916\uff0c\u6211\u4eec\u4e5f\u6709\u8ba9\u5b66\u751f\u6765\u6211\u4eec\u7684\u6559\u5ba4\u6216\u5728\u5bb6\u505a\u6a21\u8003\u7684\u670d\u52a1\u8ba9\u5b66\u751f\u8bc4\u4f30\u81ea\u5df1\u7684\u5b66\u4e60\u8fdb\u5ea6\u5e76\u770b\u5230\u6210\u7ee9\u3002\u5982\u679c\u4f60\u60f3\u9884\u7ea6\u65f6\u95f4\u6765\u6211\u4eec\u7684\u6559\u5ba4\u6216\u5728\u5bb6\u505a\u6a21\u8003\uff0c\u8bf7\u8054\u7cfb\u6211\u4eec\uff01<\/p>\n","protected":false},"excerpt":{"rendered":" \u6211\u5011\u6574\u7406\u4e86 2016\u5e74 5\u6708 SAT \u8003\u8a66\u7576\u4e2d\u7684 5 \u7bc7\u95b1\u8b80\u6587\u7ae0\uff0c\u5e6b\u52a9\u5b78\u751f\u6e96\u5099\u672a\u4f86\u7684\u8003\u8a66\u3002<\/p>\n","protected":false},"author":16,"featured_media":28371,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"","_seopress_titles_desc":"\u6211\u5011\u6574\u7406\u4e86 2016\u5e74 5\u6708 SAT \u8003\u8a66\u7576\u4e2d\u7684 5 \u7bc7\u95b1\u8b80\u6587\u7ae0\uff0c\u5e6b\u52a9\u5b78\u751f\u6e96\u5099\u672a\u4f86\u7684\u8003\u8a66\u3002","_seopress_robots_index":"","is_share_social_media":0,"is_publish_medium":0,"language":"","jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[2369,2304,2382],"tags":[],"class_list":["post-37881","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sat-cn","category-free-resources-cn","category-test-revisited-cn"],"jetpack_featured_media_url":"https:\/\/blog.ivy-way.com\/wp-content\/uploads\/2020\/07\/201605.png","views":{"total":13,"cached_at":"","cached_date":1776404420},"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/posts\/37881","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/comments?post=37881"}],"version-history":[{"count":0,"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/posts\/37881\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/media\/28371"}],"wp:attachment":[{"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/media?parent=37881"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/categories?post=37881"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.ivy-way.com\/cn\/wp-json\/wp\/v2\/tags?post=37881"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}PASSAGE 2<\/strong><\/h3>\n\n\n\n
