Making and Keeping Friends Is More than Child's Play

    When 6-year­-old Rachel returned to school on a recent Monday morning, her eyes immediately scanned the playground for her friend Abbie. “Though they were only separated by a weekend, the girls ran right into each other's arms and hugged,” recalls Rachel's mother Kathryn Willis of Gilbert. “It was like a scene from a movie.”

    Most parents instinctively (本能地) know that having friends is good for their child. Experts agree that friendship isnot simply child's play, but a powerful predictor of social adjustment throughout life.

A Skill for Life

  “Childhood friendships serve as a very important training ground for adulthood,” says Dr. Robbie Adler­Tapia, psychologist with the Center for Children's Health & Life Development at the East Valley Family Resource Center.

    Researcher William Hartup states,“Peerrelations contribute significantly to both social and cognitive (认知的) development.” Hartup concludes that the single best childhood predictor of adult social adaptation is not school grades or classroom behavior, butrather, how well a child gets along with other children.

    The work of Arizona State University professor of Developmental Psychology Gary Ladd proves that just as being ableto make and keep friends is beneficial to kids while the lack of friends is detrimental.

Good Friendships Don't Just Happen

    Experts agree that it is essential forchildren to establish high­quality friendships. But, researchers warn, these friendships don't necessarily just happen. Often, a good friendship begins with involvedparents.

    Psychologist Dr. Lynne Kenney Markan believes kids should be taught social skills in much the same way they are taught math and reading.

Bad Company

Many parents worry about the quality aswell as the quantity of their child's friendships. “When she was in 1st grade, her supposed ‘best friend' began calling her names and threatening to hurt her,”says Mindy Miller. “My daughter wasn't allowed to talk to or even look at other girls in her class. It really crushed her spirit. I told my daughter she didn't need a ‘friend' like that.”

    “I'll bend over backwards(拼命) to help my son get together with a friend I think is good for him,” Adler­ Tapiasays. “I don't look at it as manipulation (操纵)，just positive parental involvement.”

    Two recent studies have found that punishment is not the best way to influence behavior.

    One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.

    They had about two hundred college students play a version of the game known as the Prisoner's Dilemma. The game is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players. Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded the most earned about twice as much in the game as the groups that rewarded the least. And the more a group punished itself, the lower its earnings. The study appeared last month in the journal Science.

    The other study involved children. It was presented last month in California at a conference on violence and abuse（虐待）. Researchers used intelligence tests given to two groups. More than eight hundred children were aged two to four the first time they were tested. More than seven hundred children were aged five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not.

    The study says the IQs of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points. The more they are spanked, the slower their mental development.

    "City Cycling USA: Los Angeles," a pocket-sized tour guide to seeing Los Angeles on two wheels, is seemingly for visitors; Actually, for locals, its series of bike-friendly paths and itineraries (行程) are a road-map to becoming tourists in their own city again.

    "City Cycling" explores five neighborhoods in the Westside and Eastside and generally north of the 10 and south of the 101. Itineraries fit the period of a day, beginning with spots for coffee, walking along museums and shops, and finishing off with recommendations of where to buy a well-deserved drink. Published by Thames and Hudson in association with London cycling brand Rapha Racing, the guidebook is among the first U.S. sections — alongside New York, Chicago and San Francisco — in a series launched in 2013 with biking tours of eight European cities.

    Greatest hits such as the Bradbury Building and Echo Park Lake are included in the neighborhood tours, with plenty of fashionable places for where to eat — Eggslut, Pine & Crane and Gjusta. The guide is a reminder of how crowdedly packed each enclave (飞地) of L.A. is with unusual destinations, the large number of places to explore within a few square mile radius (半径), easily done once we step out of the car.

    Los Angeles' famously pleasant weather makes it an ideal city for exploring by bike; neighborhoods have different styles. While the car still plays an important role, cycling culture, like CicLAvia, already has full support, and is prepared to grow with the implementation (实施) of Mobility Plan 2035, which aims to make the city more bike friendly. "City Cycling USA: Los Angeles" is a start.

    Solar energy systems/power plants do not produce air pollution, water pollution, or greenhouse gases. Using solar energy can have a positive, indirect effect on the environment, when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment.

    However, some poisonous materials and chemicals are used to make the photovoltaic (光电池的) cells that convert sunlight into electricity. Some solar thermal (保热的) systems use potentially hazardous liquids to transfer heat. Leaks of these materials could be harmful to the environment. U. S. environmental laws regulate the use and settlement of these types of materials.

    As with any type of power plant, large solar power plants can affect the environment near their locations. The placement of the power plant may have long-term effects on the habitats of native plants and animals. Some solar power plant-s may require water for cleaning solar collectors and concentrators or for cooling turbine generators. Using large volumes of ground water or surface water in some dry locations may affect the ecosystems that depend on these water resources. In addition, the beam of concentrated sunlight a solar power tower creates can kill birds and insects that fly into the beam.

    The amount of solar energy that the earth receives each day is many times greater than the total amount of all energy that people consume each day. However, on the surface of the earth, solar energy is a variable and irregular energy source. The amount of sunlight and the intensity of sunlight varies by time of day and location. Weather and climate conditions affect the availability of sunlight daily and on a seasonal basis. The type and size of a solar energy collection and conversion system determines how much of the available solar energy we can convert into useful energy.

    People with an impulsive(冲动的) personality refer to those who tend to do things without considering the possible dangers or problems first. According to a new study by researchers at the University of Georgia, such people may be more likely to have food addiction. The study found that people exhibiting impulsive behavior weren't necessarily overweight, but impulsiveness was related to a direct relationship with food, and therefore, less healthy weight.

    Food addiction has been compared to addictive drug use. Studies have linked the dopamine (多巴胺) release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.

    Impulsive behavior involves several personality traits (特点). Two of these traits, known as negative urgency and lack of perseverance, were particularly associated with food addiction and high BMI (身体质量指数) during the study.

    Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions. Some people might drink alcohol or take drugs. For others, it could mean eating to feel better. Lack of perseverance is when a person has a hard time finishing hard or boring tasks. People with a lack of perseverance might have difficulty attempting to change addictive eating behavior, which could also cause obesity.

    "Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight," said Dr. Ashley Gearhardt, a clinical psychologist. He was involved in developing the Yale Food Addiction Scale in aid of those people. "We are theorizing that if food addiction is really a thing, then our measure, the Yale Food Addiction Scale, should be related to helping control impulsive action," said Gearhardt.

    Clinical psychologist Dr. James MacKillop, whose lab was conducting the study, believes that therapies(治疗，疗法)used to treat addictive drug behavior could help people who suffer from addictive eating habits.

    "Most of the programs for weight loss at this point focus on the most obvious things, which are clearly diet and exercise," MacKillop said. "It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily."

The age of technology is a great and convenient thing, but it does have effects on us in many different ways.

It causes long-term memory loss. Thanks to Baidu, we don't really have to remember much of anything. Questions are answered at the drop of a hat because Baidu is all-knowing! Is that a good thing, though? People aren't digging through their brains anymore to find answers. Here's the good news: we can still exercise our long-term memory by simply thinking before we Baidu. If we don't want to go down that road, we can search Baidu for some memory games to play. Turn Baidu into an asset instead of an enemy.

It makes us lack patience. Baidu gives us what we want. Everything is instant. In fact, if we have to wait for even a handful of minutes for anything, we start losing our minds. This idea of instant satisfaction carries through to many other aspects of our lives, too, like when we go out to eat, drive in traffic, or even deal with workplace accidents. Instead of using Baidu to lessen our anger, try searching for some mindful meditations (沉思).Focus on our breath and realize everything doesn't have to move at lightening speed. We can actually listen to some peaceful spa or meditation music on our Pandora, too!

It wastes our time. Be honest, how much time are we spending on Baidu every day? Whether we're doing research for our own personal needs, buying clothing, or writing a research paper, we all spend a ton of time on the trusty Internet. Are we always being efficient with this time? For the sake of our precious time, if we haven't used Baidu Drive, we should. Keep spreadsheets, text does, PDFs, slideshows, and even recordings exactly where we can easily find them. Keep a running list of websites we know we'll revisit.

Overall, things are different these days. Yes, there are noticeable negative side effects because of the Baidu invasion, but we don't have to fall into that trap. Stay sharp and don't let ourselves become imprisoned doing the Baidu god's bidding.
