Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard Ffrench-Constant, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.

    There is no better way to enjoy Scottish traditions than going fishing and tasting a little whisky(威士忌) at a quiet place like the Inverlochy Castle. When Queen Victoria visited there in 1873 she wrote in her diary, “I never saw a lovelier spot,” And she didn't even go fishing.

    Scotland is not easily defined. In certain moments, this quiet land of lakes and grass mountains changes before your very eyes. When evening gently sweeps the hillside into orange, the rivers, teeming with fish, can turn into streams of gold. As you settle down with just a people and a basket on the bank of River Orchy, near the Inverlochy Castle, any frustration will float away as gently as the circling water. It's just you and purple, pink, white flowers, a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime's fun. For many, fishing is more than a sport; it is an art.

    Scotland offers interesting place where you can rest after a long day's fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland's mountains. Ben Nevis is the highest of mountains, and reaching its 1342-metre top is a challenge. But it's not just what goes up that matters; what comes down is unique. More than 900 metres high, on the mountain's north face, lies an all-important source of pure water. Its name comes from the Gaelic language "usqueb" or "water of life"; and it is the single most important ingredient(原料) in Scotland's best known whisky.

    As he applied sunscreen to his young daughter's face, Dara O'Rourke, a professor of environmental and labor policy at the University of California, Berkeley, found himself wondering if the lotion(霜) was safe. He realized there was no readily available answer. The result—two years, a team of chemists, lots of testing and venture capital(风险投资) later—is GoodGuide. com. Launched in 2008, this is a website with a smart phone app that rates 140, 000 consumer products (only in America) according to their safety, environmental sustainability and the ethics of the firms that make them. Now GoodGuide has created a new “purchase analyzer” app designed to inform consumers not just about the values attached to products, but also about whether they are the virtuous(有信誉的) shoppers they say they want to be.

    Using the new app requires selecting a series of characteristics, which range from whether the user favours organic products to buying only from firms with a good human-rights record. Consumers then scan the bar code on a product with the camera in their smart phones. The app identifies it and checks in a database to score it. Much therefore depends on the quality of the data, which GoodGuide gathers from various sources, including government reports, scientific studies, and research by its own staff. If the product scores badly, the app will recommend an alternative item which is rated more highly. The app also tracks a consumer's purchases to see how well he lives up to his selected values, giving a sort of personal virtue rating.

    So far, GoodGuide has mostly been used by shoppers who are keen to know about any issues connected with products they buy. They are mothers concerned about a child's health, older people facing a chronic(慢性的) illness or supporters of a cause, such as animal rights. The hope behind the app is that the idea of finding out about a product's background will become the mainstream.

    Consumers rarely change their buying habits, even when provided with scientific and other data, says Mr O'Rourke. So he has drawn on insights from behavioral economics, which show shoppers can be greatly influenced by peer pressure and by information passed on to them by people they know. The app tries to take advantage of these pressures. The virtue rating will inform consumers how well they are doing according to the values they espouse(拥护). That measurement encourages them to do better. Soon, the rating will be able to be shared with others on social media sites such as Facebook, which could inspire a shopper to consume more thoughtfully.

    Philosophy of Education is a label applied to the study of the purpose, process, nature and ideals of education. It can be considered a branch of both philosophy and education. Education can be defined as the teaching and learning of specific skills, and the imparting of knowledge, judgment and wisdom, and is something broader than the societal institution of education we often speak of.

    Many educationalists consider it a weak and imprecise field, too far removed from the practical applications of the real world to be useful. But philosophers dating back to Plato and the Ancient Greeks have given the area much thought and emphasis, and there is little doubt that their work has helped shape the practice of education over the millennia.

    Plato is the earliest important educational thinker, and education is an essential element in “The Republic” (his most important work on philosophy and political theory, written around 360 B.C.). In it, he advocates some rather extreme methods: removing children from their mothers' care and raising them as wards of the state, and differentiating children suitable to the various castes(社会等级), the highest receiving the most education, so that they could act as guardians of the city and care for the less able. He believed that education should be holistic(全面的), including facts, skills, physical discipline, music and art. Plato believed that talent and intelligence is not distributed genetically and thus is to be found in children born to all classes, although his proposed system of selective public education for an educated minority of the population does not really follow a democratic model.

    Aristotle considered human nature, habit and reason to be equally important forces to be cultivated in education, the ultimate aim of which should be to produce good and virtuous citizens. He proposed that teachers lead their students systematically, and that repetition be used as a key tool to develop good habits, unlike Socrates' emphasis on questioning his listeners to bring out their own ideas. He emphasized the balancing of the theoretical and practical aspects of subjects taught, among which he clearly mentions reading, writing, mathematics, music, physical education, literature, history, and a wide range of sciences, as well as play, which he also considered important.

    During the period of Middle Age, the idea of Perennialism was first formulated by St. Thomas Aquinas in his work “De Magistro”. Perennialism holds that one should teach those things deemed to be of everlasting importance to all people everywhere, namely principles and reasoning, not just facts (which are apt to change over time), and that one should teach first about people, not machines or techniques. It was originally religious in nature, and it was only much later that a theory of worldly Perennialism developed.

    During the Renaissance(文艺复兴), the French doubter Michel de Montaigne (1533 - 1592) was one of the first to critically look at education. Unusually for his time, Montaigne was willing to question the conventional wisdom of the period, calling into question the whole structure of the educational system, and the assumption that university-educated philosophers were necessarily wiser than uneducated farm workers, for example.

    I have been passionate about sewing and fashion design since I was 12. Two years ago, I designed and made a set of outfits from recyclable materials for a charity fashion show. Through this highly meaningful and profound experience, I became sensitized to the importance of protecting and preserving our environment when designing and making fashion items, resulting in my founding an organization to promote eco-friendly design and fashion.

    My interest has led me to research areas of fashion that have environmental implications. For example, some popular clothing stores have announced merchandizing policies designed to improve the environment. For those of us who are eco-conscious, it is incumbent upon us to evaluate whether such policies are just a marketing ploy, or represent genuine efforts to protect our environment.

    Three chain-stores, H&M, Urban Outfitters and Forever 21, have been promoting "green" items. After I examined their products, I have concluded that H&M and Urban Outfitters are truly helping the environment with their efforts, while Forever 21 seems to be using the 'go green' trend as a way to sell more products, rather than genuinely help the environment.

    Of these three stores, H&M has the most extensive eco-fashion plans. It is already well on its way to implementing its plans by increasingly blending organic cotton into their garments, as well as putting fully organic cotton items on the market. The store also belongs to the Organic Exchange Organization, which endorses growth of organic cotton. To reduce the substantial harm from non-organic cotton production, H&M is involved with the Better Cotton Initiative. Mindful of the adverse effects of climate change, the store aims to minimize transportation and energy usage. H&M labels their eco-friendly products with an official symbol, the Flower, to represent a production system that is less harmful than most traditional processes. Because of these actions and policies, H&M is already well on its way to making a difference on the environment.

    With its Urban Renewal brand, Urban Outfitter takes a different approach from H&M in promoting eco-friendly fashion. The brand features women's apparel made from strictly environmentally-friendly sources, such as vintage, dead stock, or surplus clothing. Urban Renewal produces fashionable garments, and embraces being eco-friendly through recycling.

    Unlike the other two stores above, Forever 21's eco-fashion efforts fall short; a cynic would say their message is downright misleading. It promotes the "'green" image, and yet many of their supposed eco-friendly products do not help the environment. For example, it sells a "Think Green Tote" that, according to the site, is meant "to send an environmentally friendly message". However, it is made of 100% non-organic cotton which is one of the most damaging fabrics to the environment, mostly because it requires greater chemical intervention compared to organic cotton. Also, the "I Love My Planet Tote" is supposed to "make a positive statement," but is also made of 100% cotton that is not organic. The only tote that is environmentally-friendly is the "H81 Organic Cotton Tote" from Forever 21's Heritage brand, made from 100% organic cotton. Now that Forever 21 has portrayed itself as being "green," it should start "walking the walk."
