People of every culture tell each other fairy tales but the same story often takes a variety of forms in different parts of the world. In the story of Little Red Riding Hood that European children are familiar with, a young girl on the way to see her grandmother meets a wolf and tells him where she is going. The wolf runs on ahead and disposes of the grandmother, then gets into bed dressed in the grandmother’s clothes to wait for Little Red Riding Hood. You may think you know the story – but which version? The universal appeal of these tales is frequently attributed to the idea that they contain cautionary messages: in the case of Little Red Riding Hood, to listen to your mother, and avoid talking to strangers. ‘It might be what we find interesting about this story is that it’s got this survival-relevant information in it,’ says anthropologist Jamie Tehrani at Durham University in the UK. But his research suggests otherwise. ‘We have this huge gap in our knowledge about the history and prehistory of storytelling, despite the fact that we know this genre is an incredibly ancient one,’ he says. That hasn’t stopped anthropologists, folklorists and other academics devising theories to explain the importance of fairy tales in human society. Tehrani’s analysis focused on Little Red Riding Hood in its many forms, which include another Western fairy tale known as The Wolf and the Kids. Checking for variants of these two tales and similar stories from Africa, East Asia, and other regions, he ended up with 58 stories recorded from oral traditions. First, he tested some assumptions about which aspects of the story alter least as it evolves, indicating their importance. Folklorists believe that what happens in a story is more central to the story than the characters in it. However, Tehrani found no significant difference in the rate of evolution of incidents compared with that of characters. Neither did his analysis support the theory that the central section of a story is the most conserved part. But the really big surprise came when he looked at the cautionary elements of the story. ‘Studies on hunter-gatherer folk tales suggest that these narratives include really important information about the environment and the possible dangers that may be faced there – stuff that’s relevant to survival. Yet in his analysis such elements were just as flexible as seemingly trivial details. What, then, is important enough to be reproduced from generation to generation? The answer, it would appear, is fear – blood-thirsty and gruesome aspects of the story, such as the eating of the grandmother by the wolf, turned out to be the best preserved of all. Why are these details retained by generations of storytellers, when other features are not? Tehrani has an idea: ‘In an oral context, a story won’t survive because of one great teller. It also needs to be interesting when it’s told by someone who’s not necessarily a great storyteller.’ Maybe being swallowed whole by a wolf, then cut out of its stomach alive is so gripping that it helps the story remain popular, no matter how badly it’s told. Mathias Clasen at Aarhus University in Denmark isn’t surprised by Tehrani’s findings. ‘Habits and morals change, but the things that scare us, and the fact that we seek out entertainment that’s designed to scare us – those are constant,’ he says. Clasen believes that scary stories teach us what it feels like to be afraid without having to experience real danger, and so build up resistance to negative emotions

Can you imagine your life without advertisements? They are present in all sectors of our lives, in our homes on TV, on public means of transport, in the streets, in newspapers, you name it. It is only natural that all this advertising with its intrusive nature would have an impact on our lives, and many people would agree that this impact is on the whole a negative one. Adverts are very creative and attract our attention; they are also highly persuasive and influence the way we think. Their aim is to make us believe we will feel a certain way if we purchase the product which is being advertised. For example, many adverts for products show good-looking, successful people enjoying themselves and consuming or using a specific product. This plays on our psychology and our sense of self-worth, and it makes us want to buy the product so that we can look and feel like the models in the adverts. Images and lifestyles aren't the only thing that advertising imposes on us. Artificial needs are also imposed on us. We are constantly exposed to visual and verbal adverts which try to convince us that our lives will be improved if we buy a particular product. Don't tell me the plasma TV or the air freshener advertised on TV is a necessity. However, clever advertising creates in people a sense of need for material goods, which if they don't acquire, can often lead to feelings of inferiority and unhappiness. Advertising also gives a distorted picture of reality, which creates unrealistic expectations, particularly among young children and teenagers. Many adverts are targeted specifically at these age groups, creating an intense desire to own a particular product. The resulting pressure on parents is so great that they often give in to the demands of their children in order to avoid confrontation and tantrums, thus creating patterns of consumption and gratification at the expense of other values in life. This vicious cycle can have a very detrimental effect on children and, consequently, the future of society. Advertising today, with its ubiquity and aggressive nature, poisons our minds with false ideals and instils in people a sense of dissatisfaction. It turns people into materialistic consumers; this is a far cry from the self-assured, informed individuals who know the real value of money and are able to develop the sensible shopping habits that any healthy society needs.

There are many types of family systems around the world. In North America and northern Europe, the nuclear family (with two generations - a father, a mother and one or more children) is often seen as the most typical. In contrast, in most other parts of the world, extended families, which include other family members such as grandparents, aunts, uncles and cousins, are seen as the norm.  The common view is that the nuclear family has become the norm in many Western societies as a result of industrialization and urbanization. This trend began in the late eighteenth and nineteenth centuries, when people were forced to move to cities to find work in the factories that sprang up during the Industrial Revolution. In the twentieth century, greater industrialization resulted in even more people leaving their large extended families. Urbanization also meant that people lived in much smaller houses, which were not big enough for an extended family.  The trend towards nuclear families meant that many of the duties and responsibilities of a family, such as providing food and shelter, cleaning the home, preparing the food, caring for children and their education, and caring for the sick and elderly are no longer shared among the members of the extended family. The parents (or parent) now have to do this, with some help from the state. However, this is the price that people pay for the higher standard of living that may come from living in a city.  We may think we know what we mean by a ‘nuclear' family and an extended family, but reality is more complicated than most people believe. Most nuclear families are part of extended families: children have grandparents and, in many cases, aunts, uncles and cousins as well. Part of what makes them ‘nuclear' is that they live in their own separate household, but it is not the whole story. In Greece or Italy, for example, a nuclear family may live in its own flat, but the extended family may live in the same apartment block or in the same street and family members see each other and even eat together every day.  There is at least one more factor to consider. Family members may be separated from each other by geographical distance, but they may have close emotional ties. Even in North America and northern Europe, grandparents usually have close bonds with their grandchildren, and families often travel long distances so that they can see each other. Grandparents often help their adult children, for example, by cooking and looking after their children in emergencies. In the same way, when their parents become too old to live on their own, adult children may take them into their own homes. As a result, they turn their nuclear family into an extended family.  The structure of families changes over time. The effects of urbanization and industrialization are enormous, but they are not the only reasons for the changes. People marry, have children, become widowed, divorce and die. Children grow up and adults grow old. Nuclear families become extended families and extended families become nuclear families. Family ties stay strong or become weak. One thing is certain: in a changing world, the family will continue to change, but ultimately, it is likely to continue to be the basic unit of society.

Edward Patrick Eagan was born on April 26th 1897 in Denver, Colorado, and his father died in a railroad accident when Eagan was only one year old. He and his four brothers were raised by his mother, who earned a small income from teaching foreign languages. Inspired by Frank Marriwell, the hero of a series of popular novels for boys, Eagan pursued an education for himself and an interest in boxing. He attended the University of Denver for a year before serving in the U.S. army as an artillery lieutenant during World War I. After the war, he entered Yale University and while studying there, won the US national amateur heavyweight boxing title. He graduated from Yale in 1921, attended Harvard Law School, and received a Rhodes scholarship to the University of Oxford where he received his A.M. in 1928. While studying at Oxford, Eagan became the first American to win the British amateur boxing championship. Eagan won his first gold medal as a light heavyweight boxer at the 1920 Olympic Games in Antwerp, Belgium. Eagan also fought at the 1924 Olympics in Paris as a heavyweight but failed to get a medal. Though he had taken up the sport just three weeks before the competition, he managed to win a second gold medal as a member of four-man bobsled team at the 1932 Olympics in Lake Placid, New York. Thus, he became the only athlete to win gold medals at both the Summer and Winter Olympics.

Universities love overseas students – they are clever and hardworking, they bring different cultures to seminars and student life and they pay their way. In Britain, universities are getting ready to enroll more overseas students. The British Council has published a report predicting that overseas student numbers could soar to more than 800,000 by 2018. In 2010, figures put the total at over 400,000 international students out of two and a half million students in UK higher education and it is clear that this influx is having an enormous impact on universities and colleges. These students bring welcome fees, of course, but they are also likely to be very intelligent students who inject new cultural influences and bring changes to the old university systems. Their demand for vocational subjects such as business, biotechnology and information technology, rather than traditional academic subjects, is affecting what is taught as well. The impressive expansion of foreign students has already had a significant impact on higher education. Overseas student numbers, including European Union students, have risen from 270,000 in 2002 to 400,000 in 2010. During this time the number from China jumped more than tenfold, and numbers from India have been going up. In contrast, the number of students from other countries has fallen, reflecting their governments’ efforts to educate more of their young people at home, as well as competition from Australia and the USA. But as the Asian tiger economies expand their own universities, the good news for places like the London School of Economics is that there are more and more graduates looking to improve their qualifications or to pursue research in their subjects.

Sometimes our parents don't understand us. They don't understand some problems and things which are very important in teens' life; for example, the lifestyles of young people, piercing, tattoos, drugs, sex, relationship with friends and teachers. So, sometimes teens can't tell them about their private life. Some parents don't want to understand modern views, ideals and system of values.  Elderly people usually compare their childhood and youth with the present, and regard old times as better, always talking about "the good old days”. The young people, on the other hand, tend to think their times as the best. Teens look at the world with fresh eyes. Everything is new, interesting to them. Sometimes they cannot solve their everyday problems. But they want to cope with them by themselves. So, adults shouldn't prevent them from making their own mistakes.  People are said to become wiser with age. Sometimes, it is true and sometimes it is not. I think that you can meet a wise man among the old as often as among the young. It is false that when old age wisdom has come, useless illusions have disappeared. Sometimes when we talk to adults, a monologue is a preferred form of expressing your ideas in such talks. That's why some teens don't like to talk to adults.  I think that it's in people's nature to give advice. It seems to people that giving advice they can help somebody or put somebody on the right track. But if a person takes their advice and fails, he can blame an adult all of his life.  Our parents have their own ideas and views that their children don't share and understand. They think that their children won't find their place in life. They often say that now teens are very difficult to socialize with and dumpy. But children should settle all problems peacefully because they are their parents. They brought them up with loving care. And if children come to their parents for advice and help, they will do their best and help children to cope with problems and difficulties.

The Spring festival season in Vietnam starts with the Lunar New Year and closes with the celebration honoring the mythical founding fathers, the Hung Kings, on the tenth day of the third lunar month.  Underlying the origins of these rituals is the farming cycle and its association with fertility rites and ancestor worship. Ancestor worship is a belief of wet-rice farmers who keep their ancestors' graves in their village. This strong attachment to the village of one's birth and the recognition that the inhabitants all descend from the same ancestral line creates strong bonds. The village festival is based on the spirit of unity and family. The farmers are the festivals' creators, actors and audience.  Ancient ceremonies related to farming sometimes take on additional meanings: the commemoration of heroic deeds and the village heroes' birth or death. Each village in the North of Vietnam has such a heroic or super-human figure as a tutelary or guardian spirit. The heroes were honored in their own temples and communal houses which became the heart of the village activities.  There are basic themes which are common to all Spring festivals in the Red River Delta. For instance, water takes on an essential role. Water is collected and blessed and later used for ritual washing. There are boat races, fishing contests, snake dances and water puppet performances. In Chem village, in the suburbs of Hanoi on the banks of the Red River, the main part of the festival actually occurs on a barge carrying over 200 people waving flags, singing, dancing and chasing a unicorn. The barge sails from the temple out into the middle of the Red River, while elders in smaller boats fetch three large jars of water to be blessed and used in rituals during the year. The next day the blessed water is used for the symbolic washing of the wooden statue of the village guardian.

I first noticed it in a restaurant. The place was oddly quiet, and at one table a group sat with their heads bowed, their eyes hooded and their hands in their laps. I then realised that every one, whatever their age group, was gazing at a handheld phone or tablet. People strolled in the street outside likewise, with arms at right angles, necks bent and heads in awkward postures. Mothers with babies were doing it. Students in groups were doing it. The scene resembled something from an old science fiction film. There was no conversation. Every visit to California convinces me that the digital revolution is over, by which I mean it is won. Everyone is connected. The New York Times last week declared the death of conversation. While mobile phones may at last be falling victim to considerate behaviour, this is largely because even talk is considered too intimate a contact. No such bar applies to emailing, texting, messaging, posting and tweeting. It is ubiquitous, the ultimate connectivity, the brain wired full-time to infinity. The MIT professor and psychologist Sherry Turkle claims that her students are close to mastering the art of maintaining eye contact with a person while texting someone else. It is like an organist playing different tunes with hands and feet. To Turkle, these people are ‘alone together … a tribe of one’. Anyone with 3,000 Facebook friends has none. The audience in many theatres now sit, row on row, with lit machines in their laps, looking to the stage occasionally but mostly scrolling and tapping away. The same happens at meetings and lectures, in coffee bars and on jogging tracks. Psychologists have identified this as ‘fear of conversation’, and have come up hmmm with the term ‘conversational avoidance devices’ for headphones. In consequence, there is now a booming demand for online ‘conversation’ with robots and artificial voices. Mobiles come loaded with customised ‘boyfriends’ or ‘girlfriends’. People sign up with computerised dating advisors, even claim to fall in love with their on-board GPS guides. The ‘post-digital’ phenomenon, the craving for live experience, is showing a remarkable vigour. The US is a place of ever greater congregation and migration, to parks, beaches and restaurants, to concerts, rock festivals, ball games. Common interest groups, springing up across the country, desperately seek escape from the digital dictatorship, using Facebook and Twitter not as destinations but as route maps to meet up with real people Somewhere in this cultural mix I am convinced the desire for friendship will preserve the qualities essential for a civilised life, qualities of politeness, listening and courtesy. Those obsessed with fashionable connectivity and personal avoidance are not escaping reality. They may be unaware of it but deep down they, too, still want someone to talk to.

Time management: two words that have me breaking out in a cold sweat. Why should I suddenly have to learn how to manage my time? Surely time had got on perfectly well for several millennia without requiring management, let alone by me. But my university tutor was adamant: time needed some managing and apparently it was up to me to do it.  First of all, let's be clear. I do have plenty of time to manage. As an arts student, I generally have 23 hours in the day that aren't given over to going to lectures. But I generally need somebody to tell me what I should be writing, so I go to lectures.  Perhaps I had "taken on too much"? I'd been elected to four committees, produced a play, applied for a part time job, hung around the college bar with my friends, and written the odd essay. But I thought I was coping well. Sure, there was the day when I did the research for an essay on the morning of deadline day and wrote it that afternoon, but that was a one off.  On second thoughts, maybe my tutor is right. It's difficult to give up what you're involved in but perhaps it's a good idea to sit back and have a breather once in a while. Even an arts student has to get down to some real work!
