第一篇 摘自new yorker

 

Another man might have thrown up his hands—but not Nawabdin. The 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—the salary he received from K. K. Harouni for tending the tube wells would not even begin to suffice. He set up a one-room flour mill, run off a condemned electric motor—condemned by him. He tried his hand at fish-farming in a pond at the edge of one of his master’s fields. He bought broken radios, fixed them, and resold them. He did not demur even when asked to fix watches, although that enterprise did spectacularly badly, and earned him more kicks than kudos, for no watch he took apart ever kept time again.

K. Harouni lived mostly in Lahore and rarely visited his farms. Whenever the old man did visit, Nawab would place himself night and day at the door leading from the servants’ 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 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.

 

 

Harouni, of course, became familiar with this ubiquitous man, who not only accompanied him on his tours of inspection but could be found morning and night standing on the master bed rewiring the light fixture or poking at the water heater in the bathroom. 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.

 

“Sir, 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”—here he bowed his head to show the gray—“and 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.”

 

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.

 

“What’s the matter, Nawabdin?”

 

“Matter, sir? Oh, what could be the matter in your service? I’ve eaten your salt for all my years. But, sir, on the bicycle now, with my old legs, and with the many injuries I’ve received when heavy machinery fell on me—I 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 service. I beg you, sir, let me go.”

 

“And what is the solution?” Harouni asked, seeing that they had come to the crux. He didn’t particularly care one way or the other, except that it touched on his comfort—a matter of great interest to him.

 

“Well, sir, if I had a motorcycle, then I could somehow limp along, at least until I train up some younger man.”

 

The crops that year had been good, Harouni felt expansive 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.

 

The motorcycle increased his status, gave him weight, so that people began calling him Uncle and asking his opinion on world affairs, about which he knew absolutely nothing. He could now range farther, doing much wider business. Best of all, now he could spend every night with his wife, who early in the marriage had begged to live not in Nawab’s quarters in the village but with her family in Firoza, near the only girls’ school in the area. A long straight road ran from the canal headworks near Firoza all the way to the Indus, through the heart of the K. K. Harouni lands. The road ran on the bed of an old highway built when these lands lay within a princely state. Some hundred and fifty years ago, one of the princes had ridden that way, going to a wedding or a funeral in this remote district, felt hot, and ordered that rosewood trees be planted to shade the passersby. Within a few hours, he forgot that he had given the order, and in a few dozen years he in turn was forgotten, but these trees still stood, enormous now, some of them dead and looming without bark, white and leafless. Nawab would fly down this road on his new machine, with bags and streamers 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.

 

 

 

 

 

第二篇 选自 Public Trust In The News

 

The news is a form of public knowledge. Unlike personal or private knowledge (such as the health of one’s friends and family; the conduct of a private hobby; a secret liaison), public knowledge 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 warzone—these 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.

 

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 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’s definition of authority as the ‘power over, or title to influence, the opinions of others’. 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:

 

Editors are increasingly casting a glance at the ‘most read’ lists on their own and other websites to work out which stories matter to readers and viewers. And now the audience—which used to know its place—is being asked to act as a kind of journalistic ombudsman, ruling on our credibility. (Broadcast journalist,2008)

 

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)

 

Despite the rhetorical bluster of these statements, they amount to more than straightforward professional defensiveness. In their reference to an audience ‘which used to know its place’ and conflation between democratisation and ‘dumbing down’, 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 ‘informative rather than authoritative’ (FG1); the job of journalists should be to ‘give the news as raw as it is, without putting their slant on it’ (FG5) and people should be given ‘sufficient information’ from which ‘we would be able to form opinions of our own’ (FG1).

 

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 themonline); the parity of popular culture with ‘serious’ news; the demands of some audience members for raw news rather than constructed narratives.

 

 

 

3 第三篇 选自 American Scientist

 

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 “when you advertise [to pollinators], you advertise in an open communication network,” says chemical ecologist Ian Baldwin of the Max Planck Institute for Chemical Ecology in Germany. “You attract not just the good guys, but you also attract the bad guys.” For a Texas gourd plant (Cucurbita pepo variety texana), striped cucumber beetles (Acalymma vittatum) 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.

 

The gourd vine’s problem—how to attract enough pollinators but not too many beetles—is a specific case of a floral dilemma that biologists first noticed many decades ago. In 1879, Austrian botanist Anton Kerner von Marilaun published a treatise titled The Protective Means of Flowers against Unbidden Guests, in which he described glands and sticky hairs that seemed to help keep harmful insects at bay. But a century later, scientists had still barely begun to consider the contribution of a flower’s scent to those interactions; to do so would require a convergence of fieldwork, chemistry and molecular biology. “We’re just beginning to train the type of biologists who can use those tools,” Baldwin says. The resulting experiments have begun to reveal the many ways that floral fragrances may manipulate animal behavior.

 

In one recent study, published in the February issue of Ecology, Nina Theis and Lynn Adler took on the specific problem of the Texas gourd. Its main pollinators are honey bees (Apis mellifera) and specialized squash bees (Peponapis pruinosa), which respond to its floral scent. The aroma includes 10 compounds, but the most abundant—and the only one that lures squash bees into traps—is 1,4-dimethoxybenzene.

 

Intuition suggests that more of that aroma should be even more appealing to bees. “We have this assumption that a really fragrant flower is going to attract a lot of pollinators,” says Theis, a chemical ecologist at Elms College in Chicopee, Massachusetts. But, she adds, that idea hasn’t really been tested—and 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 half the 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.

 

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 by beetles.

 

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.

 

“It was very labor intensive,” says Theis. “We would be out there at four in the morning, three in the morning, to try and set up before these flowers open.” As soon as they did, the team spent the next several hours walking from flower to flower, observing each for two-minute intervals “and writing down everything we saw.”

 

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.

 

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’t rescue the seed set, indicating that beetles damaged flowers directly—regardless 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.)

 

The new results provide a reason that Texas gourd plants never evolved to produce a stronger scent: “If you really ramp up the odor, you don’t get more pollinators, but you can really get ripped apart by your enemies,” says Rob Raguso, a chemical ecologist at Cornell University who was not involved in the Texas gourd study. “It’s kind of like asking ‘What if antlers were longer or larger or heavier? Is there some threshold above which they’re actually a burden?’” For Texas gourd, there is—and Raguso, with ecologist Candace Galen and their coauthors, reached a similar conclusion in February 2011, in an American Naturalist paper on alpine skypilot (Polemonium viscosum). Too much fragrance could harm those flowers, too, but for a completely different reason.

 

 

 

 

 

第四篇对比 来自林肯和梭罗

1 by Abraham Lincoln

 

 

The question recurs, “how shall we fortify against it?” The answer is simple. 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;–let 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’s liberty. Let reverence for the laws, be breathed by every American mother, to the lisping babe, that prattles on her lap–let it be taught in schools, in seminaries, and in colleges; let it be written in Primers, spelling books, and in Almanacs;–let 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.

 

While ever a state of feeling, such as this, shall universally, or even, very generally prevail throughout the nation, vain will be every effort, and fruitless every attempt, to subvert our national freedom.

 

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.

 

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 interposition of mob law, either necessary, justifiable, or excusable.

 

 

2 by Henry David Thoreau

 

Unjust laws exist: shall we be content to obey them, or shall we endeavour 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 does it not cherish its wise minority? Why does it cry and resist before it is hurt? Why does it not encourage its citizens to be on the alert to point out its faults, and do better than it would have them? Why does it always crucify Christ and excommunicate Copernicus and Luther, and pronounce Washington and Franklin rebels?

 

One would think, that a deliberate and practical denial of its authority was the only offense never contemplated by government; else, why has it not assigned its definite, its suitable and proportionate penalty? If a man who has no property refuses but once to earn nine shillings for the state, he is put in prison for a period unlimited by any law that I know, and determined only by the discretion of those who placed him there; but if he should steal ninety times nine shillings from the state, he is soon permitted to go at large again.

 

If the injustice is part of the necessary fiction of the machine of government, let it go, let it go: perchance it will wear smooth – certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, 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.

 

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’s 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. It is not my business to be petitioning the Governor or the Legislature any more than it is theirs to petition me; and if they should not hear my petition, what should I do then? But in this case the state has provided no way: its very constitution is the evil. This may seem to be harsh and stubborn and unconciliatory; but it is to treat with the utmost kindness and consideration the only spirit that can appreciate or deserves it. So is all change for the better, like birth or death, which convulses the body.

 

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 of Massachusetts, 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.

What Tech Is Next for the Solar Industry?

 

Solar power, for all its recent cost reductions, remains more expensive than fossil fuel power.

Solar panel installations continue to grow quickly, but the solar panel manufacturing industry is in the doldrums because supply far exceeds demand (see “Why We Need More Solar Companies to Fail”). 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.

 

 

The technology that’s 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’d never go below $1 a watt. “Now it’s down to something like 50 cents of watt, and there’s talk of hitting 36 cents per watt,” he says.

 

The U.S. Department of Energy has set a goal of reaching less than $1 a watt—not just for the solar panels, but for complete, installed systems—by 2020 (see “Why Solar Installations Cost More in the U.S. than in Germany”). 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. (The total cost of solar power, which includes the cost to utilities to compensate for its intermittency, would be higher, though precisely how much higher will depend on how much solar power is on the grid, and other factors.)

 

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’s 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’s lab built a solar cell in the 1990s that set a record efficiency for silicon solar cells—a 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—about the width of the lines Green used for his record solar cells, but at costs far lower than his lithography techniques.

 

Green says this and other techniques will make it cheap and practical to replicate the designs of his record solar cell on production lines. Some companies have developed manufacturing techniques for the front metal contacts. Implementing the design of the back electrical contacts is harder, but he expects companies to roll that out next.

 

Meanwhile, researchers at the National Renewable Energy Laboratory have made flexible solar cells on a new 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—thin-film cadmium telluride (see “First Solar Shines as the Solar Industry Falters”). Flexible solar cells could lower the cost of installing solar cells, making solar power cheaper.

 

One of Green’s 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’t 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.

 

Such solar panels could be mounted vertically, like a fence, so that one side collects sunlight in the morning, and the other in the afternoon. That would make it possible to install the solar panels on very little land—they could serve as noise barriers along highways, for example. Such an arrangement could also be valuable in dusty areas. Many parts of the Middle East might seem to be good places for solar panels, since they get a lot of sunlight, but frequent dust storms decrease the power output. Vertical panels wouldn’t accumulate as much dust, which could help make such systems economical.

 

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 a part of the solar spectrum that silicon doesn’t 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.[anti-both]
