Plogging
Plogging is a new way to jog while cleaning up the planet. It's a craze that began in Sweden in 2016 and the motivation behind it includes reducing the load of plastic litter in our environment, as well as keeping fit while running. 1.If you love outdoor exercise, enjoy exercising with others, and care about removing litter from our environment, then this might just be the sport for you.
Make good preparations before plogging. Dress suitably for the environment in which you are running. This will vary depending on the weather and surroundings, but the basics are comfortable running clothes and closed-toe running shoes. Suitable gloves are a wise and useful addition, as picking up litter can be dangerous in some situations. 2.This might be a standard trash bag, easy to carry and capable of containing litter that might have sharp edges.
Organize your plogging group. If you're lucky enough to have ploggers already in your area, seek them out. Join up and make new friends with a shared interest. Check out such meeting groups at Meetup or ask at a local sports store to find out what opportunities exist where you live. If you don't have a group, create one. Use social media, notices on bulletin boards, or place signs in the windows of sports stores to find fellow ploggers. 3.
Collect safely. One key suggestion for staying safe while collecting litter is to avoid picking up broken glass or sharp items. If you must collect such an item, only do so when you can find a very safe way to collect it without harming yourself. If in doubt, leave it and get better equipment to remove it. 4.If an item of litter presents a potential safety risk, try to mark the item clearly to encourage people to avoid it.
5. It is a way of combining individual achievement via exercise with community and environmental care. You're part of the growing movement of people who are giving back to the world at the same time as honoring self care, a sustainable and healthy way to balance your life. This could be a fantastic opportunity to show people that individual action makes a big difference.
A. Taking some photos during the process is also necessary.
B. You can also ask for assistance from the local authorities.
C. Usually performed as part of a group run, it's also a social exercise.
D. You also need to find a suitable carry bag for collecting the litter in.
E. Plogging is a great way to feel motivated as it has more than one benefit.
F. If you find a natural area with litter problem, this might be a suitable place.
G. With some advertising effort, you are likely to connect with a few interested people.
According to a new study， teens focus on rewards and have a hard time learning to avoid punishment or consider the consequences of alternative actions.
University College London researchers compared how teens and adults learn to make choices based on the available information. They tracked the way in which 18 volunteers aged 12-17 and 20 volunteers aged 18-32 completed tasks in which they had to choose between abstract symbols.
Each symbol was consistently associated with a fixed chance of a reward, punishment, or no outcome. As the trial progressed ， participants learned which symbols were likely to lead to each outcome and adjusted their choices accordingly. Teens and adults were equally good at learning to choose symbols associated with reward， but teens were less good at avoiding symbols associated with punishment. Adults also performed significantly better when they were told what would have happened if they had chosen the other symbol after each choice， while teens did not appear to take this information into account.
“From this experimental lab study we can draw conclusions about learning during the teen years. We find that teens and adults learn in different ways， something that might be relevant to education," said lead author Dr. Stefano Palminteri. " Unlike adults, teens are not so good at learning to adjust their choices to avoid punishment. This suggests that incentive systems based on reward rather than punishment may be more effective for this age group. Additionally, we found that teens did not learn from being shown what would have happened if they made alternative choices."
To interpret the results, the researchers developed computational models of learning and ran simulations （模拟）applying them to the results of the study. The first was a simple model, one that learned from rewards, and the second model added to this by also learning from the option that was not chosen. The third model was the most complete and took the full context into account, with equal weight given to punishment avoidance and reward seeking. For example, obtaining no outcome rather than losing a point is weighted equally to gaining a point rather than having no outcome.
Comparing the experimental data to the models, the team found that teens" behavior followed the simple reward-based model while adults" behavior matched the complete, contextual model. “Our study suggests that teens are more receptive to rewards than they are to punishments of equal value, ” said senior author Dr. Sarah-Jayne Blakemore. “As a result, it may be useful for parents and teachers to frame things in more positive terms.”
