OxfordWhen language learners arrive in Oxford, many ask where the university is, thinking that they will be shown just one building. It´s up to their teachers to explain that Oxford university is made up of a collection of many different colleges and institutions, each with its own history and characteristics.There are many other surprises that learners discover about the city and its university. Katie Jennings is a social organizer at King´s St Joseph´s Hall in East Oxford, and it is her job to organize activities for learners outside of lesson time. She says many learners are surprised to discover that Oxford is a home to a wide variety of nationalities and ethnic groups, and one of the most popular social events is a night out at one of the town´s Latin American dance clubs. After a day spent learning English and absorbing the ancient atmosphere of the university, learners can samba the night away.The city also has a thriving Asian community, and the sight of women in saris is as common in Oxford´s streets as academics in gowns and mortarboards. There is also a mouth-watering selection of Asian restaurants serving curries, as well as shops stocked with exotic vegetables and fruits.The city has attracted such a diverse population not only because of the university, but also because it is an important industrial centre which is known for car manufacturing among other things. In spite of large industrial areas, the old of the city centre has remained surprisingly intact. Carmel Engin, who teaches at the Lake School, says many learners are surprised to find that the city is free from the usual high-rise modem buildings. "From the centre of Oxford, you can see green hills in the distance, and this will make learners deeply feel that they are in a small, friendly town, but not just another modem metropolis.Some learners will be tempted to explore those green hills—Oxford is surrounded by some of the most beautiful countryside in southem England—but, as Engin admits, with so much to do and see in the city, few learners find the time to explore its surroundings.Oxford has developed some imaginative initiatives for language learners. One is a local radio station which broadcasts news and provides information for learners. They can visit the station to get experience in radio production. Or they can meet university students in pubs and clubs or at one of the many campus sports facilities which are open to language learners.

When night falls in remote parts of Africa and the Indian subcontinent, hundreds of millions of people without access to electricity turn to candles or flammable and polluting kerosene lamps for illumination.Slowly through small loans for solar powered devices, microfinance is bringing light to these rural regions where a lack of electricity has stymied economic development, literacy rates and health. A woman sews clothes on a sewing machine driven by solar energy in Ahmedabad/Photo credit: Amit Dave/Reuters."Earlier, they could not do much once the sun set. Now, the sun is used differently. They have increased their productivity, improved their health and socio-economic status," said Pinal Shah from SEWA Bank, a micro-lending institution.Vegetable seller Ramiben Waghri took out a loan to buy a solar lantern which she uses to light up her stall at night. The lantern costs between $66-$112, about a week´s income for Waghri."The vegetables look better by this light, and it´s cheaper than kerosene and doesn´t smell," said Waghri, who estimates she makes about 300 rupees ($6) more each evening with her lantern."If we can use the sun to save some money, why not?"In India, solar power projects, often funded by micro credit institutions, are helping the country reduce carbon emissions and achieve its goal to double the contribution of renewable energy to 6%, or 25,000 megawatts, within the next four years.Off-grid applications such as solar cookers and lanterns, which can provide several hours of light at night after being charged by the sun during the day, will help cut dependence on fossil fuels and reduce the fourth biggest emitter´s carbon footprint, said Pradeep Dadhich, a senior fellow at energy research institute TERI."They are reaching people who otherwise have limited or no access to electricity, and depend on kerosene, diesel or firewood for their energy needs," he said."The applications not only satisfy these needs, they also improve the quality of life and reduce the carbon footprint."SEWA or Self Employed Women´s Association, is among a growing number of microfinance institutions in India focused on providing affordable renewable energy sources to poor people, who otherwise would have had to stand for hours to buy kerosene for lamps, or trudge miles to collect firewood for cooking.SKS Microfinance, India´s largest MFI, offers solar lamps to its 5 million customers, while Grameen Surya Bijlee (Rural Solar Electricity) Foundation helps fund lamps and home and street lighting systems for villagers in India, Nepal and Bangladesh.

Tourism, Globalization and Sustainable DevelopmentTourism is one of the fastest growing sectors of the global economy and developing countries are attempting to cash in on this expanding industry in an attempt to boost foreign investment and financial reserves. While conceding that the uncontrolled growth of this industry can result in serious environmental and social problems, the United Nations contends that such negative effects can be controlled and reduced.Before getting into the cold facts of global economics, let me begin with another story to warm up. I was perplexed when I recently read in the newspaper that Thailand´s forestry chief had said: "Humans can´t live in the forest because human beings aren´t animals. Unlike us, animals can. adapt themselves to the wild or any environment naturally." This was to legitimatize the government´s plan to remove hundreds of thousands of rural and hill tribe people from protected areas. This man, who is in charge of conserving the forests, is at the same time very strongly pushing to open up the country´s 81 national parks to outside investors and visitors in the name of "eco-tourism". Can we conclude, then, that the forestry chief considers developers and tourists as animals that know how to adapt to the forest and behave in the wild naturally?While authorities want to stop the access to forest lands and natural resources of village people, another group of people -- namely tourism developers and tourists with lots of money to spend -- are set to gain access to the area. While authorities believe that local people, who have often lived in the area for generations, are not capable of managing and conserving their land and natural resources -- under a community forestry scheme for example -- they believe they themselves in cooperation with the tourist industry can properly manage and conserve "nature" under a national eco-tourism plan. Taking the above quote seriously, cynics may be tempted to say there is obviously a gap between "human rights" and "animal fights".How is this story linked to globalization? First of all, that humans cannot live in the forest is -- of course -- not a Thai concept. It is a notion of Western conservation ideology -- an outcome of the globalization of ideas and perceptions. Likewise, that eco-tourism under a "good management" system is beneficial to local people and nature is also a Western concept that is being globalized. In fact, Thailand´s forestry chief thinks globally and acts locally. A lesson that can be learned from this is that the slogan "Think Globally, Act Locally" that the environmental movements have promoted all the years, has not necessarily served to preserve the environment and safeguard local communities´ rights, but has been co-opted and distorted by official agencies and private industries for profit-making purposes. The tourism industry is demonstrating this all too well.Many developing countries, facing debt burdens and worsening trade terms, have turned to tourism promotion in the hope that it brings foreign exchange and investment. Simultaneously, leading international agencies such as the World Bank, United Nations agencies and business organizations like the World Travel & Tourism Council (WTTC) have been substantially involved to make tourism a truly global industry.However, tourism in developing countries is often viewed by critics as an extension of former colonial conditions because from the very beginning, it has benefited from international economic relationships that structurally favor the advanced capitalist countries in the North. Unequal trading relationships, dependence on foreign interests, and the division of labor have relegated poor countries in the South to becoming tourism recipients and affluent countries in the North to the position of tourism generators, with the latter enjoying the freedom from having to pay the price for the meanwhile well-known negative impacts in destinations.

For more than 30 years, I have been wondering about L.R. Generson. On one of our first Christmases together, my husband gave me a complete set of Dickens. There were 20 volumes, bound in gray cloth with black corners, old but in good condition. Stamped on the flyleaf of each volume, in faded block letters, was the name of the previous owner: "L.R. Generson, M.D., Bronx, NY."That Dickens set is one of the best presents anyone has ever given me. A couple of the books are still pristine, but others—"Bleak House," "David Copperfield," and especially "Great Expectations"—have been read and re-read almost to pieces. Over the years, Pip and Estella and Magwitch have kept me company. So have Lady Dedlock, Steerforth and Peggotty, the Cratchits and the Pecksniffs and the Veneerings. And so, in his silent enigmatic way, has L.R. Generson.Did he love the books as much as I do? Who was he? On a whim, I Googled him. There wasn ´ t much—a single mention on a veterans´ website of a World War Ⅱ captain named Leonard Generson. But I did find a Dr. Richard Generson, an oral surgeon living in New Jersey. Since Generson is not a common name, I decided to write to him.Dr. Generson was kind enough to write back. He told me that his father, Leonard Richard Generson, was born in 1909. He lived in New York City but went to medical school in Basel, Switzerland. He spoke 10 languages fluently. As an obstetrician and gynecologist, he opened a practice in the Bronx shortly before World War Ⅱ . His son described him as "an extremely patriotic individual"; right after Pearl Harbor he closed his practice and enlisted. He served throughout the war as a general surgeon with an airborne special forces unit in Europe, where he became one of the war´s most highly decorated physicians.The list of his decorations reflects his ordeals and his courage: multiple Purple Hearts, the Bronze Star with "V" for valor, the Silver Star, and also the Cross of War, an extremely high honor from the government of France. After the war, he remained in the Army Reserve and attained the rank of full colonel, while also continuing his medical practice in New York. "He was a very dedicated physician who had a large patient following," his son wrote.Leonard Generson´s son didn´t remember the Dickens set, though he told me that there were always a lot of novels in the house. His mother probably "cleaned house" after his father´s death in 1977—the same year my husband bought the set in a used book store.I found this letter very moving, with its brief portrait of an intelligent, brave man and his life of service. At the same time, it made me question my presumption that somehow L.R. Generson and I were connected because we´d owned the same set of books. The letter both told me a little about him, and told me that I would never really know anything about him—and why should I? His son must have been startled to hear from a stranger on such a fragile pretext. What had I been thinking?One possible, and only somewhat facetious, answer is that I´ve read too much Dickens. In the world of a Dickens novel, everything is connected to everything else. Orphans find families. Lovers are joined (or parted and morally strengthened). Ancient mysteries are solved and old scores are settled. Questions are answered. Stories end.Dickens´s cluttered network of connected lives brilliantly exaggerates something that is true of all of us. We want to impose order through telling stories, maybe because there is so much we don´t know about our own stories and the stories of those around us.Leonard Generson´s life touched mine only lightly, through the coincidence of a set of books. But there are other lives he touched more deeply. The next time I read a Dickens novel, I will think of him and his military service and his 10 languages. And I will think of the hundreds of babies he must have delivered, who are now in the middle of their own lives and their own stories.

Plans are well under way for a year of celebrations to mark the upcoming bicentennial of one of Poland´s favorite native sons-Frédéric, Chopin.The prestigious International Chopin Competition for pianists will mark its 16th edition in October 2010. Held every five years, the competition draws scores of young musicians from all over the world. In addition, Warsaw´s Chopin Museum, with the world´s largest collection of Chopin documents and other artifacts, will undergo a total redesign, modernization and expansion.A lavishly illustrated new guidebook called "Chopin´s Poland" was already published this year. It leads visitors to dozens of sites in Warsaw and elsewhere around the country where the composer lived, ate, studied, performed, visited or even partied."Actually, Chopin doesn´t need to be promoted, but we hope that Poland and Polish culture can be promoted through Chopin," said Monika Strugala, who is coordinating the Chopin 2010 program under the aegis of the Fryderyk Chopin Institute, a body set up by the Sejm in 2001 to promote and protect Chopin´s work and image."We want to confirm to all that he is a very, very important Polish symbol," she said. Indeed, it´s not much of an exaggeration to say that Chopin´s music flows through the Polish national consciousness like some sort of cultural lifeblood.The son of a Polish mother and a French émigré father, Chopin was born in a manor house at Zelazowa Wola, about 50 kilometers, or 30 miles, west of Warsaw, and moved to Warsaw as an infant.The manor is something of a Chopin shrine—since the 1930s it has been a museum and center for concerts. Like the Chopin Museum in Warsaw, it, too, is undergoing extensive renovation as part of bicentennial preparations.Chopin spent his first 20 years in and around Warsaw. He was already a noted pianist as a boy and composed concertos and other important works as a teenager. He carried Polish soil with him when he left Warsaw on a concert tour in 1830, just a few weeks before the outbreak of the November Uprising, an abortive Polish revolt against Czarist Russia, which then ruled Warsaw and a broad swath of Polish territory.Chopin remained in exile in France after the uprising was crushed. But so attached was he to his native land that after his death in Paris in 1849 his heart—on his own instructions— was brought back to Warsaw for interment. The rest of his body is buried in the Père Lachaise cemetery in Paris."For where your treasure is, there your heart will be also," reads the Biblical inscription on a plaque where his heart is kept today, preserved in an urn and concealed in a pillar of the Holy Cross Church in central Warsaw. Mozart´s "Requiem" will be performed here as part of Bicentennial events.Exile and patriotism, as well as extraordinary genius, have long made Chopin´s appeal transcend all manner of social and political divides.Polish folk motifs thread through some of his finest pieces, and patriotic fervor, as well as homesick longing, infuse some of his best-known works.

Power and Cooperation: An American Foreign Policy for the Age of Global PoliticsThe age of geopolitics in American foreign policy is over; the age of global politics has begun. Throughout the twentieth century, traditional geopolitics drove U. S. thinking on foreign affairs: American security depended on preventing any one country from achieving dominion over the Eurasian landmass. That objective was achieved with the collapse of the Soviet Union. Now the United States finds itself confronting a new international environment, one without a peer competitor but that nonetheless presents serious threats to American security. The terrorists who struck the World Trade Center and the Pentagon neither represented a traditional state-based threat nor were fled to a specific geographical location. Nevertheless, nineteen people with just a few hundred thousand dollars succeeded in harming the most powerful nationon earth.For more than three centuries, the dynamics of world politics was determined by the interplay among states, especially the great powers. Today, world politics is shaped by two unprecedented phenomena that are in some tension with each other. One is the sheer predominance of the United States. Today, as never before, what matters most in international politics is how -- and whether -- Washington acts on any given issue. The other is globalization, which has unleashed economic, political, and social forces that are beyond the capacity of any one country, including the United States, to control.American primacy and globalization bring the United States great rewards as well as great dangers. Primacy gives Washington an unsurpassed ability to get its way in international affairs, while globalization enriches the American economy and spreads American values. But America´s great power and the penetration of its culture, products, and influence deep into other societies breed intense resentment and grievances. Great power and great wealth do not necessarily produce greater respect or greater security. American leaders and the American people are now grappling with the double-edged sword that is the age of global politics.

obal IndustrializationIndustrialization changed the world. Few places on earth have escaped its impact. However, the nature of the impact varies from place to place. Understanding the global consequences of industrialization requires an understanding of how industrialization differed in each place.Industrialization is always initially a regional, not a national, phenomenon as demonstrated by the long industrial lag of the American South. Many other parts of Western Europe plus the United States followed Britain in the early 19th century. A few other European regions -- Sweden, Holland, northern Italy -- began serious industrialization only at mid-century. The next big wave of new industrialization, beginning around the 1880s, embraced Russia and Japan. A final round (to present) included the rapid industrialization of the rest of the Pacific Rim (especially South Korea and Taiwan) by the 1960s.Various factors shaped the nature of industrialization in each place. In Britain, for example, industrialization succeeded when it depended on individual inventors and relatively small companies. It began to lag, however, in the corporate climate of the later 19th century. In contrast, Germany surged forward when industrialization featured larger organizations, more impersonal management structures, and collaborative research rather than artisan-tinkerers. In Germany, the state was also more directly involved in industrialization than in Britain.French industrialization emphasized updated craft products. This reflected not only earlier national specialties, but also less adequate resources in coal, a factor that held heavy industry back. Furniture workers, for example, used pre-set designs to turn out furniture quickly, but they resented dilutions of their artistic skill. The United States´ industrialization depended on immigrant labor. Unlike Germany, however, the United States introduced laws that combated businesses big enough to throttle competition, though the impact of these laws was uneven. The United States with its huge market also pioneered the new economic stage of mass consumerism that ultimately had a worldwide impact.The consequences of industrialization are, ultimately, global. By the early 19th century, Europe´s factories pushed back more traditional manufacturing in areas like Latin America and India. At the same time, industrial centers sought new food resources and raw materials, prompting these sectors to expand in places like Chile and Brazil.Gradually, however, other societies copied industrialization or at least developed an independent industrial sector. Much of 20th-century world history, in fact, involves efforts by societies like India, China, Iran, or Brazil to reduce their dependence on imports and mount a selective export operation through industry. Industrialization´s environmental impact has also been international. Industrialization quickly affected local water and air quality around factories. Industrial demands for agricultural products, like robber, caused deforestation and soil changes in places like Brazil. These patterns have accelerated as industrial growth has spread more widely, creating modern issues such as global warming. The world impact of industrialization, in these senses, remains an unfinished story as the 21st century begins.Given the global impact of industrialization, it is increasingly important that we understand its nature and its consequences. Whereas the impact of industrialization is easy to understand on a personal level -- how it affects where and how we work or live our lives -- it is more difficult to understand its nature on a global level, particularly when its global pattern is so complex. History provides a means toward this understanding. By understanding the causes, the variations, and the historic consequences of the Industrial Revolution, we can better understand our present circumstances and, hopefully, shape future industrializations for the good.

The Environment in Perspective:Is Everything Getting Steadily Worse?Much of the discussion of environmental problems in the popular press leaves the reader with the impression that matters have been growing steadily worse, and that pollution is largely a product of the profit system and modern industrialization. There are environmental problems today that are both enormous and pressing, but in fact pollution is nothing new. Medieval cities were pestholes—the streets and rivers were littered with garbage and the air stank of rotting wastes. At the beginning of the eighteenth century, a German traveler reported that to get a view of London from the tower of St. Paul´s, one had to get there very early in the morning "before the air was full of coal smoke."Since 1960 there has been progress in solving some pollution problems, much of it the result of concerted efforts to protect the environment. The quality of the air in most Canadian cities has improved. In Toronto, for example, the concentration of suspended particulates, or soot, in the air has fallen dramatically since 1962. To put this figure in perspective, it should be noted that the current health advisory level for the index is 32. At a level of 58, people with chronic respiratory diseases may be affected. At 100, even healthy people may be affected by prolonged conditions, and those with cardiac and respiratory diseases could suffer severe effects.Recently in Toronto, the index has exceeded 32 on fewer than half a dozen days annually. Similar improvements have occurred elsewhere in Canada and in other industrialized countries. Even the famous, or rather infamous, "fogs" of London are almost a thing of the past. There have been two high readings of particular note in the British capital in 1959 (when the index rose to 275 and there was a 10 percent increase over the normal number of deaths) and in 1962 (when the index rose to 575 and there was a 20 percent increase in mortality ). But more recently, London´s, cleaner air has resulted in an astounding 50 percent increase in the number of hours of winter sunshine. In short, pollution problems are not a uniquely modem phenomenon, nor is every part of the environment deteriorating relentlessly.Environmental problems do not occur exclusively in capitalist economies. For example, in the People´s Republic of China, coal soot from factory smokestacks in Beijing envelops the city in a thick black haze. Similarly, smoke from brown-coal furnaces pollutes the air almost everywhere in Eastern Europe. It has been estimated that a third of Poland´s citizens live in areas of "ecological disaster". The citizens of Leipzig, a major industrial city in what was formerly East Germany, have a life expectancy a full six years shorter than the national average.However, we do not mean to suggest that all is well with the environment in market-oriented economies or that there is nothing more to do. While there have been some improvements, serious problems remain. Our world is now subject to a number of new pollutants, most of which are far more dangerous than those we have reduced, even though they may be less visible and less malodorousWhile environmental problems are neither new nor confined only to capitalist, industrialized economies, these facts are not legitimate grounds for complacency. The potential damage that we are inflicting on ourselves and on our surroundings is very real and very substantial.

One of the biggest decisions Andy Blevins has ever made, and one of the few he now regrets, never seemed like much of a decision at all. It just felt like the natural thing to do.In the summer of 1995, he was moving boxes of soup cans, paper towels and dog food across the floor of a supermarket warehouse, one of the biggest buildings here in southwest Virginia. The heat was brutal. The job had sounded impossible when he arrived fresh off his first year of college, looking to make some summer money, still a skinny teenager with sandy blond hair and a narrow, freckled face.But hard work done well was something he understood, even if he was the first college boy in his family. Soon he was making bonuses on top of his $6.75 an hour, more money than either of his parents made. His girlfriend was around, and so were his hometown buddies. Andy acted more outgoing with them, more relaxed. People in Chilhowie noticed that.It was just about the perfect summer. So the thought crossed his mind: maybe it did not have to end. Maybe he would take a break from college and keep working. He had been getting C´s and D´s, and college never felt like home, anyway."I enjoyed working hard, getting the job done, getting a paycheck," Mr. Blevins recalled. "I just knew I didn´t want to quit."So he quit college instead, and with that, Andy Blevins joined one of the largest and fastest-growing groups of young adults in America. He became a college dropout, though nongraduate may be the more precise term.Many people like him plan to return to get their degrees, even if few actually do. Almost one in three Americans in their mid-20´s now fall into this group, up from one in five in the late 1960´s, when the Census Bureau began keeping such data. Most come from poor and working-class families. That gap had grown over recent years. "We need to recognize that the most serious domestic problem in the United States today is the widening gap between the children of the rich and the children of the poor," Lawrence H. Summers, the president of Harvard, said last year when announcing that Harvard would give full scholarships to all its lowest-income students. "And education is the most powerful weapon we have to address that problem."Andy Blevins says that he too knows the importance of a degree. Ten years after trading college for the warehouse, Mr. Blevins, 29, spends his days at the same supermarket company. He has worked his way up to produce buyer, earning $35,000 a year with health benefits and a 401(k) plan. He is on a path typical for someone who attended college without getting a four-year degree. Men in their early 40´s in this category made an average of $42,000 in 2000. Those with a four-year degree made $65,000.Mr. Blevins says he has many reasons to be happy. He lives with his wife, Karla, and their year-old son, Lucas, in a small blue-and-yellow house in the middle of a stunningly picturesque Appalachian valley."Looking back, I wish I had gotten that degree," Mr. Blevins said in his soft-spoken lilt. "Four years seemed like a thousand years then. But I wish I would have just put in my four years."Why so many low-income students fall from the college ranks is a question without a simple answer. Many high schools do a poor job of preparing teenagers for college. Tuition bills scare some students from even applying and leave others with years of debt. To Mr. Blevins, like many other students of limited means, every week of going to classes seemed like another week of losing money."The system makes a false promise to students," said John T. Casteen Ⅲ, the president of the University of Virginia, himself the son of a Virginia shipyard worker.

LONGYEARBYEN, Norway—With plant species disappearing at an alarming rate, scientists and governments are creating a global network of plant banks to store seeds and sprouts, precious genetic resources that may be needed for man to adapt the world´s food supply to climate change.This week, the flagship of that effort, the Global Seed Vault near here, received its first seeds, millions of them. Bored into the middle of a frozen Arctic mountain topped with snow, the vault´s goal is to store and protect samples of every type of seed from every seed collection in the world.As of Thursday, thousands of neatly stacked and labeled gray boxes of seeds—peas from Nigeria, corn from Mexico—reside in this glazed cavelike structure, forming a sort of backup hard drive, in case natural disasters or human errors erase the seeds from the outside world.Descending almost 500 feet under the permafrost, the entrance tunnel to the seed vault is designed to withstand bomb blasts and earthquakes. An automated digital monitoring system controls temperature and provides security akin to a missile silo or Fort Knox. No one person has all the codes for entrance.The Global Vault is part of a broader effort to gather and systematize information about plants and their genes, which climate change experts say may indeed prove more valuable than gold. In Leuven, Belgium, scientists are scouring the world for banana samples and preserving their shoots in liquid nitrogen before they become extinct. A similar effort is under way in France on coffee plants. A number of plants, most from the tropics, do not produce seeds that can be stored.For years, a hodgepodge network of seed banks has been amassing seed and shoot collections in a haphazard manner. Labs in Mexico banked corn species. Those in Nigeria banked cassava. Now these scattershot efforts are being urgently consolidated and systematized, in part because of better technology to preserve plant genes and in part because of the rising alarm about climate change and its impact on world food production."We started thinking about this post-9/11 and on the heels of Hurricane Katrina," said Cary Fowler, president of the Global Crop Diversity Trust, a nonprofit group that runs the vault. "Everyone was saying, why didn´t anyone prepare for a hurricane before? We knew it was going to happen."Well, we are losing biodiversity every day—it´s a kind of drip, drip, drip. It´s also inevitable. We need to do something about it."This week the urgency of the problem was underscored as wheat prices rose to record highs and wheat stores dropped to the lowest level in 35 years. A series of droughts and new diseases cut wheat production in many parts of the world. "The erosion of plants´ genetic resources is really going fast," said Dr. Rony Swennen, head of the division of crop biotechnology at the Catholic University of Leuven in Belgium, who has preserved half of the world´s 1,200 banana types. "We´re at a critical moment and if we don´t act fast, we´re going to lose a lot of plants that we may need."The United Nations International Treaty on Plant Genetic Resources, ratified in 2004, created a formal global network for banking and sharing seeds, as well as for studying their genetic traits. Last year, its database received thousands of new seeds.A system of plant banks could be crucial in responding to climate crises since it could identify genetic material and plant strains better able to cope with a changed environment.Here at the Global Vault, hundreds of gray boxes containing seeds from places ranging from Syria to Mexico were moved this week into a freezing vault to be placed in suspended animation. They harbor a vast range of qualities, like the ability to withstand drier, warmer climate.

As digital technologies and automation have advanced,fears about workers" futures have increased. But, the end result does not have to be negative. The key is education.Already, robots are taking over a growing number of routine and repetitive tasks, putting workers in some sectors under serious pressure. In South Korea, which has the world’s highest density of industrial robots — 631 per 10,000 workers — manufacturing employment is declining, and youth unemployment is high. In the United States, the increased use of robots has, according to a 2017 study, hurt employment and wages.But while technological progress undoubtedly destroys jobs, it also creates them. The invention of motor vehicles largely wiped out jobs building or operating horse-drawn carriages, but generated millions more not just in automobile factories, but also in related sectors like road construction.The challenge today lies in the fact that the production and use of increasingly advanced technologies demand new, often higher-level skills, which cannot simply be picked up on the job. Given this, countries need to ensure that all of their residents have access to high-quality education and training programs that meet the needs of the labor market. The outcome of the race between technology and education will determine whether the opportunities presented by major innovations are seized, and whether the benefits of progress are widely shared.In a report by the Economist Intelligence Unit (EIU), 66% of executives surveyed were dissatisfied with the skill level of young employees, and 52% said a skills gap was an obstacle to their firm’s performance. Meanwhile, according to a survey,21% of workers reported feeling over-educated for their jobs.This suggests that formal education is teaching workers the wrong things, and that deep reform is essential to facilitate the development of digital knowledge and technical skills, as well as non-routine cognitive and non-cognitive (or “soft”) skills. This includes the “four Cs of twenty_first century learning”(critical thinking, creativity, collaboration, and communication) — areas where humans retain a considerable advantage over artificially intelligent machines.The process must begin during primary education, because only with a strong foundation can people take full advantage of later education and training. And in the economy of the future,that training will never really end. Given rapid technological progress, improved opportunities for effective lifelong learning will be needed to enable workers to upgrade their skills continuously or learn new ones. At all levels of education, curricula should be made more flexible and responsive to changing technologies and market demands.One potential barrier to this approach is a dearth of well-trained teachers. Building a quality teaching force will require both monetary and non-monetary incentives for teachers and higher investment in their professional development.This includes ensuring that teachers have the tools they need to take full advantage of information and communication technology (ICT), which is not being used widely, despite its potential to ensure broad access to lifelong learning through formal and informal channels.ICT can also help to address shortages of qualified teachers and other educational resources by providing access across long distances, via online learning platforms. For example, the Massachusetts Institute of Technology’s OpenCourseWare enables students around the world to reach some of the worlds foremost teachers.This points to the broader value of international cooperation. The education challenges raised by advancing technologies affect everyone, so countries should work together to address them, including through exchanges of students and teachers and construction and upgrading of ICT infrastructure.The artificial intelligence revolution will be hugely disruptive, but it will not make humans obsolete. With revamped education systems, we can ensure that technological progress makes all of our lives more hopeful,fulfilling, and prosperous.
US enrollment of international students declined for the second year in a row,sending waves of unease across American colleges and universities, which see students from abroad as a buffer against the falling number of US high-school students graduating each year.The number of new international students enrolling at American institutions fell by 6.6 percent during the 2017-18 academic year, on top of a 3.3 percent decline the year before, according to a report by the Institute of International Education.The drop takes the number of new students back to the level seen three or four years ago. At the University of Central Missouri, foreign enrollment surged to 2,600 in 2016 before plummeting to just 650 this year. At Purdue University, one of the nation"s biggest hubs for international students, total foreign enrollment fell by 2 percent this year.Meanwhile, the total number of international students in the US plus those working here on a student visa rose by just 1.5 percent this year. That was down from average annual growth of 6.1 percent over the past decade, a period during which enrollment of international students doubled.Similar to previous years, the largest numbers of students came from China, India and South Korea, which together made up 56.1 percent of all international students.The US is also losing students to English-speaking countries such as Canada, Australia and the UK, which have all seen growth in the past year. Canada reported a 20 percent jump in 2017, while Australia saw a 12 percent increase. Students from abroad are still flocking to the coasts, but are less interested in the South and Midwest.Several factors are driving the decrease. Visa and immigration policy changes by the Trump administration have deterred some international students from enrolling, college administrators and immigration analysts said.A strong dollar has made US college tuition relatively more expensive; Canadian and European universities are competing fiercely for the same students and headlines about mass shootings also may have deterred some students, said Allan Goodman, president of HE.“Everything matters from safety, to cost, to perhaps perceptions of visa policy,” Goodman said. “We’re hearing that they have choices. We’re hearing that there’s competition from other countries.”The shift is due to a combination of politics, geography and branding, said Alejandra Sosa Pieroni, an international recruitment expert with a company that consults with colleges to improve enrollment.“Students are not feeling welcome in some states,so they are looking beyond those states and heading to places where they will feel welcome/5 she said.Foreign students are big business. They pumped $42 billion into US college and university coffers in the 2017-18 school year alone.International students have become an important funding source for American colleges as traditional revenue sources, such as state funding, come under pressure. Most undergraduate foreign students do not qualify for need-based financial aid and must pay full tuition and fees to attend US schools.However, the number of US students studying abroad ticked up by 2 percent last year,continuing eight years of slow but steady growth. Europe remained the top destination,followed by Latin America and Asia.
As icebergs in the Kayak Harbor pop and hiss while melting away, this remote Arctic town Narsaq (纳萨克)and its culture are also disappearing in a changing climate.Narsaq’s largest employer,a shrimp processing plant, closed a few years ago after the crustaceans fled north to cooler water. Where once there were eight commercial fishing vessels, there is now one. As a result, the population in Narsaq, one of southern Greenland's major towns, has been halved to 1,500 in just a decade. Suicides are up. “Fishing is the heart of this town,” said Hans Kaspersen,63, a fisherman. “Lots of people have lost their livelihoods.”But even as rising temperatures are upending traditional Greenlandic life, they are also offering up intriguing new opportunities for this island of 57,000 — perhaps nowhere more so than in Narsaq. Vast new deposits of minerals and gems are being discovered as Greenland’s huge ice cap recedes, forming the basis of a potentially lucrative mining industry. One of the world's largest deposits of rare earth metals — essential for manufacturing cellphones, wind turbines and electric cars ——sits just outside Narsaq.It has long been known that Greenland sat upon vast mineral lodes, and the Danish government has mapped them intermittently for decades. Niels Bohr, the Danish Nobel Prize laureate nuclear physicist and a participant in the Manhattan Project,which developed the first atomic bomb, visited Narsaq in 1957 because of its uranium deposits. But previous attempts at mining mostly failed, proving too expensive in the inclement conditions. Now, warming has altered the equation.The Greenland Bureau of Minerals and Petroleum, charged with managing the boom, has 150 active licenses for mineral exploration, up from 20 a decade ago. Altogether, companies spent US$100 million exploring Greenland's deposits last year, and several are applying for licenses to begin construction on new mines, bearing gold, iron, zinc and rare earth. There are also foreign companies exploring for offshore oil.The Black Angel Lead and Zinc Mine, which dosed in 1990, is applying to reopen this year, said Hammeken-Holm,who oversees licensing at the mining bureau, “because the ice is in retreat,you’re getting much more to explore.”In Narsaq, which features a collection of brightly painted homes bordered by spectacular fjords, two foreign companies are applying to the government for permission to mine. Narsaq9s tiny airport, previously threatened with closure due to lack of traffic, could be expanded. A local landlord is contemplating converting an abandoned apartment complex into a hotel.“There will be a lot of people coming from outside, and that will be a big challenge,since Greenlandic culture has been isolated,9, said Jasper Schroder, a student from Narsaq who attends a university in Denmark. Still, he said he supports the mine and hopes it will provide jobs and stem the rash of suicides, particularly among his peers; Greenland has one of the highest suicide rates in the world. “People in this culture don’t want to be a burden to their families if they can’t contribute,” he said.But not all are convinced of the benefits of mining. “Of course, the mine will help the local economy and will help Greenland,but I,m not so sure if it will be good for us,” said Dorothea Rodgaard,who runs a local guesthouse. “We are worried about the loss of nature.”
It has been a usual sight that the luxury liner Majestic Princess operated by Carnival Group, a global cruise company, sits charging at the Wusongkou International Cruise Terminal in Shanghai.Shore power can help ships reduce their emissions by moving away from using oil to generate energy. “Developing a shore power system for a green port is just one of the projects for eco-friendly shipping conducted by the China Merchants Group (CMG),” Fu Gangfeng,Director and Group President of CMG Ltd., a state-owned enterprise whose traditional business is shipping along the Yangtze River, told Xinhua News Agency.The shore power supply system has been in use for a year and has already contributed to 23,000 tons in reduced emissions. The Yangtze River, China’s longest waterway,is one of the busiest rivers in the world. In 2017, 2.5 billion tons of goods were delivered along this west-east water route, one of the reasons why the river has become known as a golden waterway.Compared with other methods, transportation via water has both advantages in cost and transport capacity, as well as green benefits, by saving power and reducing emissions. But the shipping lanes of the Yangtze have also caused serious environmental problems. According to statistics provided by the Ministry of Ecology and Environment, 60 percent of inland vessels are distributed in the low reaches of the Yangtze, most of which use marine fuel, a major source of pollution along the waterway. Moreover, pollution caused by industrial accidents, domestic sewage dumped by ships and heavy metal sediment from the bottom of vessels have also had a detrimental effect on the river’s ecosystem.In the Three Gorges area, diesel power generation emits around 10 tons of sulfides, 4,000 tons of carbon oxides and 3 tons of PM2.5 annually, posing a serious risk to the air qualityand ecological environment of the region. In 2017, there were 614 ships in the Three Gorges Dam area, with an average waiting time of 106 hours. During the overhaul of the ship locks in 2018, there were 1,084 ships waiting for an average duration of 202 hours. Accordingly, the supervision of activities and the entry standards for ships are hard to control, which increases the difficulty of maintaining orderly competition.During the process of improving the waterway, the concept of ecological protection is being implemented. Eco-friendly materials and structures are applied to minimize the impact on the environment in a bid to maintain a balance between regulation and protection. Building green ports is an essential and effective method of waterway regulation. In conclusion, high standards should be maintained when new ports are built and old ones are upgraded. By regulating, integrating and upgrading existing ports, the functions of the shoreline are strengthened. The use of cleaner energy in the form of liquefied natural gas (LNG) is also of great significance for the green future of the Yangtze channel. According to Fu, in terms of drybulk cargo, 50 freighters with 8,000 to 10,000 tons of LNG fleet suitable for the Yangtze will be built in the future to replace the existing 50 percent of the ship5s capacity, optimize the ship structure and reduce pollution to the environment.
It sounds so promising. A network of dedicated cycle routes runs through a city,withair pumps to fix flat tires, footrests to lean on while taking breaks and trash cans that are specially angled, so you can throw in empty water bottles without stopping.Best of all, you can cycle on those routes for long distances without having to make way for cars and trucks at junctions and traffic lights, according to the official description of the Cycle Super Highways, which are under construction here as part of the Danish capital’s efforts to become carbon-neutral by 2025.Are they as good as they sound? These days it is hard to find a big city that doesn’t make grandiose claims to encourage cycling, and harder still to find one that fulfills them. Redesigning congested traffic systems to add bike lanes to overcrowded roads is fiendishly difficult, especially in historic cities with narrow cobbled streets like Copenhagen. But as its cycling program sounds so ambitious, I went there to try it.Maybe I’d be less cynical if I lived in Amsterdam,Cologne or any other city with decent cycling facilities. But as a Londoner,I’ve learned the hard way to be suspicious whenever politicians promise to do anything bike-friendly. London's mayor, Boris Johnson, is a keen cyclist,who issues policy papers with auspicious titles like “Cycling Revolution” and has continued his predecessor’s biking program by introducing a cycle-rental project and building new bike lanes.So far, so good. You may think, unless you have braved the potholes, parked trucks and construction debris that obstruct those lanes,many of which appear to have been designed by someone who has never seen a bicycle, let alone ridden one.Luckily for Copenhagen's cyclists, their system has been more thoughtfully designed. The capital is a compact, reasonably flat city which is naturally bike-friendly, and even its old cycle routes are wider and better maintained than London’s. More than a third of Copenhageners already bike to work or school, mainly on short journeys of an average of 5 kilometers, or 3 miles.The city's traffic planners hope to encourage people to cycle for longer distances creating the cycling equivalent of freeways, which will provide fast, direct routes of up to 22 kilometers into the center. A total of 28 highways are planned, providing 495 kilometers of dedicated bike tracks. The first one from the western suburb of Albertslund opened in April 2012, followed a year later by the second, from Farum, northwest of the city.What are the super highways like? Judging by my experience of the Farum route, they’re great. Impressive though the air pumps,footrests and angled trash cans are, the biggest thrill was pedaling through the “green waves” of uninterrupted green traffic lights, which have been programmed to prioritize cyclists over cars.It was also cheering to see bikers chatting while cycling two or three abreast in“conversation lanes”. Like most urban bikers,I usually value the practical benefits of cycling, as a speedy means of transport and convenient form of exercise,but the Farum route made itas pleasurable as zipping along empty country lanes. The planners hope the foil network will eventually encourage a 30-percent increase in cycling among Copenhagen^ commuters, which would be hugely beneficial in terms of reducing the city9s C02 emissions and health care costs.
What is the single most effective way to reduce greenhouse-gas emission? Go vegetarian? Replant the Amazon? Cycle to work? None of the above. The answer is: make air-conditioners radically better. On one calculation, replacing refrigerants that damage the atmosphere would reduce total greenhouse gases by the equivalent of 90bn tonnes of C02 by 2050. Making the units more energy-efficient could double that. By contrast, if half the worlds population were to give up meat, it would save 66bn tonnes of C02. Replanting two- thirds of degraded tropical forests would save 61bn tonnes. A one-third increase in global bicycle journeys would save just 2.3bn tonnes.Air-conditioning is one of the worlds great overlooked industries. Automobiles and air- conditioners were invented at roughly the same time, and both have had a huge impact on where people live and work. Unlike cars,though,air-conditioners have drawn little criticism for their social impact, emissions or energy efficiency. Most hot countries do not have rules to govern their energy use. There is not even a common English word for “coolth”(the opposite of warmth).Yet air-conditioning has done more than most things to benefit humankind. Lee Kuan Yew, the first prime minister of Singapore,called it “perhaps one of the signal inventions of history”. It has transformed productivity in the tropics and helped turn southern China into the workshop of the world. In Europe, its spread has pushed down heat-related deaths by a factor of ten since 2003, when 70,000 more people than usual, most of them elderly, died in a heatwave. For children, air-conditioned classrooms and dormitories are associated with better grades at school (see International section).Environmentalists who call air-conditioning “a luxury we cannot afford” have half a point, however. In the next ten years, as many air-conditioners will be installed around the world as were put in between 1902 (when air-conditioning was invented) and 2005. Until energy can be produced without carbon emissions, these extra machines will warm the world. At the moment, therefore, air-conditioners created a vicious cycle. The more the Earth warms, the more people need them. But the more there are, the warmer the world will be.Cutting the impact of cooling requires three things (beyond turning up the thermostat to make rooms less Arctic). First, air-conditioners must become much more efficient. The most energy-efficient models on the market today consume only about one-third as much electricity as average ones. Minimum energy-performance standards need to be raised, or introduced in countries that lack them altogether,to push the average unit’s performance closer to the standard of the best.Next, manufacturers should stop using damaging refrigerants. One category of these, hydrofluorocarbons, is over 1,000 times worse than carbon dioxide when it comes to trapping heat in the atmosphere. And international deal to phase out these pollutants, called the Kigali Amendment, will come into force in 2019. Foot-draggers should ratify and implement it; America is one country that has not done so.Last, more could be done to design offices, malls and even cities so they do not need as many air-conditioners in the first place. More buildings should be built with overhanging roofs or balconies for shade, or with natural ventilation. Simply painting roofs white can help keep temperatures down. Better machines are necessary. But cooling as an overall system needs to be improved if air-conditioning is to fulfill its promise to make people healthier, wealthier and wiser, without too high an environmental cost. Providing indoor sanctuaries of air-conditioned comfort need not come at the expense of an overheating world.
For generations, coal has been the lifeblood of this mineral-rich stretch of eastern Utah.Mining families proudly recall all the years they toiled underground. Supply companies line the town streets. Above the road that winds toward the mines, a soot-smudged miner peers out from a billboard with the slogan “Coal = Jobs.” But recently, fear has settled in. The state"s oldest coal-fired power plant, tucked among the canyons near a town, is set to close, a result of new, stricter federal pollution regulations. As energy companies move away from coal toward cleaner, cheaper natural gas, people here have grown increasingly afraid that their community may soon slip away. Dozens of workers at the Carbon Power Plant have learned that they must retire early or seek other jobs. Local trucking and equipment outfits are preparing to take business elsewhere.“There are a lot of people worried,” said Kyle Davis, who has been employed at the plant since he was 18. Mr. Davis, 56, worked his way up from sweeping floors to managing operations at the plant, whose furnaces have been burning since 1954. t4I would have liked tobe here for another five years,” he said, “I’m too young to retire.”But the Rocky Mountain Power, the utility that operates the plant, has determined that itwould be too expensive to retrofit the aging plant to meet new federal standards on mercury emissions. The plant is scheduled to be shut by April 2015. t6We had been working for the better part of three years, testing compliance strategies,”said David Eskelsen, a spokesman for the utility. 6tNone of the ones we investigated really would produce the results that would meet the requirements.”For the last several years, coal plants have been shutting down across the country, driven by tougher environmental regulations, flattening electricity demand and a move by utilities toward natural gas. This month, the board of directors of the Tennessee Valley Authority,the country’s largest public power utility,voted to shut eight coal-powered plants in Alabama and Kentucky, and partly replace them with gas-fired power. Since 2010, more than 150 coal plants have been closed or scheduled for retirement.The Environmental Protection Agency estimates that the stricter emissions regulationsfor the plants will result in billions of dollars in related health savings and will have a sweeping impact on air quality. In recent weeks, the agency held 11 ""listening sessions95 around the country in advance of proposing additional rules for carbon dioxide emissions. “(Coal plants are the single largest source of dangerous carbon pollution in the UnitedStates,and we have ready alternatives like wind and solar to replace them,” said Bruce Nilles, director of the Sierra Club"s Beyond Coal Campaign, which wants to shut all of the nation’s coal plants.For many here, coal jobs are all they know. The industry united the area during hard times, too, especially during the dark days after nine men died in a 2007 mining accident some 35 miles down the highway. Virtually everyone around here knew the men, six of whom remain entombed in the mountainside. But there is quiet acknowledgment that this place will have to change — if not now, soon. Pete Palacios, who worked in the mines for 43 years, has seen coal roar and fade here. Now 86, his eyes grew cloudy as he recalled his first mining job. He was 12, and earned US$1 a day. “I’m retired, so I’ll be fine. But these young guys?” Pete Palacios said,his voice trailing off.

19世纪末,德国地理学家斐迪南·冯·里希霍芬(FerdinandvonRichthofen)首次提出了 “丝绸之路”的名称。在整个人类文明史上,迄今为止,还没有一种以具体日用物品命名的事物,会在长达一个世纪的时间里,在东西方引起如此广泛而深远的影响。然而重新审视这条道路在文明史上的表现,丝绸贸易并非是其唯一内容,并且这一名称也无法准确概括当时东西方文明交融的全部内容。就我们今天所能了解的情形看,除了丝绸之外,当时通过这条道路交流的还有各种香料、纸张、瓷器等。这些在今天看来十分普通的物品,在当时却代表了某一文明形态的最高成就。除这些物品之外,宗教思想和文化观念,也通过这条道路不断得以传播。由此可见,“丝绸之路”并不能完全概括这条道路的丰富文化内涵。丝绸的运输也不仅仅纯粹是一种物品的交流,而是有着深刻的文化意蕴。事实上,绵长的丝绸之路,由于其独特的地理位置和环境,华夏文明史上每一次文明的迁徙与文化的传播,都在这里留下了鲜明的印记与积淀。
