The first week of my summer campaign has been quite an experience! I'm learning the ups and downs of guiding this new journey,and I'm soon finding my footing in the wonderful world of support raising.

    Some may ask: Why do you choose a job where support raising is necessary? Why not just find a ministry that will support you without having to do any extra work?

    I had a wonderful support meeting this week where I was able to have some very good conversations with the lady I was sharing with.It blessed my soul to see her eyes light up with the same passion（热情）I felt in my heart about the ministry I was sharing with her.I kept thinking in my head "I've shared my passions with her,and she gets it."At the end of our meeting she decided to become a donor,but she gave me something extra that I haven't received from anyone else.She gave me a handmade wooden cross,small enough to carry with me.

    As soon as she handed it to me,I knew it was a gift sent from God,through an act of friendship.It's a symbol of a partnership that is developing through this journey,a symbol of how God can send us messages and a symbol of new friendships to come throughout the summer and my time in the middle east.Finally,it's a symbol of the example of what it looks like to build relationships with people who will join you in sharing with the world.It's something I'll treasure through the rest of my summer campaign,through my service in the middle east,and the rest of my life.

    Self-driving vehicles(车辆) will rely on cameras, sensors and artificial intelligence (人工智能) to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car's environment will be caught by the vehicle's camera. Another vehicle approaching at high speed on a collision (碰撞) track might not be visible until it's too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are still great.

    The usages of vehicle-to-vehicle communication contain vehicles driving together in a row, as well as safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles. From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units（RSUs）about nearby incidents or dangerous road conditions through 4G network. A high level of AI seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt according to information received in real time and to carry out cooperative behaviors. For example, a group of autonomous vehicles might avoid a route together because of possible risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.

    Further applications(应用) of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behavior.

    Academic learning is usually in the spotlight at school, but teaching elementary-age students “soft” skills like self-control and how to get along with others might help to keep at-risk kids out of criminal trouble in the future.

    Once a program called Fast Track was started in the early 1990s for more than 7,600 children of 55 schools in America. They were identified by their teachers and parents to be at high risk for developing aggressive behavioral problems. The students were randomly divided into two groups; half took part in the intervention, which included a teacher-led curriculum, parent training groups, academic tutoring and lessons in self-control and social skills. The program, which lasted from first grade through 10th grade, reduced delinquency(少年犯罪), arrests and use of health and mental health services as the students aged through adolescence and young adulthood.

    In another latest study, by looking at the data from nearly 900 students in previous findings, researchers found that about a third of the influence on future crime outcomes was due to the social and self-regulation skills the students learned from ages 6 to 11.

    The academic skills, or hard skills like learning of physics, which were taught as part of Fast Track, turned out to have less of an influence on crime and delinquency rates than did the soft skills, which are associated with emotional(情绪的) intelligence. Soft skills might include teaching kids to work cooperatively in a group or teaching them how to think about the long-term consequences when they make a decision.

    Researchers drew the conclusion that these soft skills should be emphasized even more in our education system and in our system of socializing children. Parents should do all they can to promote these skills with their children as should education policymakers. To the extent we can improve those skills, we can improve outcomes in delinquency.

    “Attention, everyone!” Miss Dalrymple looked at her class of ten-year-olds. “Today we are going to create a special card for Father's Day, which falls on this weekend.” Then she busied herself handing out the paper and art materials to her noisy pupils.

    They were a mixed punch. Some came from the rich side of the town, but the majorities were from parents who struggled to get jobs. So she had not been eager to carry out this activity.

    “Think about all the things that your dad does that make him special,” she said loudly as she approached the last table. “You can write a poem or short story thinking of the positive characteristics that make your dad special. The written part of this activity should be completed before you start to decorate your card.”

    Andrew looked at the blank page. He had never met, spoken to, or been hugged by his dad, so how could he write about him? Once when he was looking in his grandma's photo box, he had seen an old black and white photo but it was badly creased(弄皱) and difficult to recognize any clear features. She had quickly taken it from him and buried it deeply among the rest, never to be found again. After thinking for a while, he wrote:

Dear Dad,

    You are a person I do not know and would probably not recognize as I only saw an old photo of you a long time ago. I think and wonder about you often, especially when I have no one to talk to about the Saturday fixtures(体育活动). One day when I grow up I will do an Internet search to find you, but I am not sure whether I will be successful as several attempts by the Child Support Agency have not been successful. Happy Father's Day, Dad.

Love,

Andrew

    "What kind of rubbish are you?" This question might normally cause anger, but in Shanghai it has brought about complaints over the past week. On July 1st, the city introduced strict trash-sorting regulations that are expected to be used as a model for our country. Residents must divide their waste into four separate kinds and put it into specific public bins. They must do so at scheduled times, when monitors are present to ensure compliance（服从）and to inquire into the nature of one's rubbish.

    Violators face the possibility of fines and worse. They could be hit with fines of up to 200 yuan ($29). For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain bank loans or even buy train tickets.

    Shanghai authorities are responding to an obvious environmental problem. It generates 9 million tonnes of garbage a year, more than London's annual output and rising quickly. But like other cities in China, it lacks a recycling system. Instead, it has relied on trash pickers to sort out the waste, picking out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up. China produces 80 billion pairs of disposable(一次性的)chopsticks a year.

    Many residents appear to support the idea of recycling in general but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous(有害的), the differences among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and toss it by hand. Most upset are the short windows for throwing trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.

Earthworms don't move fast. But humans can accelerate the worms' spread. Fishermen often use invasive(蔓延性的) earthworms to catch fish. Many have introduced invasive earthworms to rivers, streams and lakes previously unexposed to these animals. Gardeners who use earthworms to make their soil rich may unknowingly introduce invasive ones. The worms even give rides in the mud on wheels, potted plants and road materials shipped around the nation.

But they're not everywhere yet. In the Great Lakes region, "20 percent of the land is earthworm-free," says Cindy Hale, a research biologist. Of the remaining 80 percent of land, half of the land has fewer than two earthworm species-meaning there isn't yet too much impact on the ecosystem, she explains. For these regions, she says, now is the time to take action. According to Hale, educating the public, especially fishermen, is one approach to stopping the spread of invasive earthworms. Identifying which lands are currently earthworm-free is another.

Ryan Huefimeier, a program coordinator for Great Lakes Wom Watch, has been working on a model that will help create large maps of areas with minimal(最小的) or no damage from earthworms. Ultimately, landowners can use it to identify earthworm activity on their property. once identified, lands with minimal or no earthworm damage should be protected.

But scientists suspect that once invasive earthworms arrive they can't be removed. And even if all could be, affected forests might never return to the way they were. "It's very much a story of learning to live with them," concludes Lee Frelich of the University of Minnesota's Center for Forest Ecology.

Forest ecologists have called earthworms "ecosystem engineers" because they can change or create habitats that otherwise would not be present. Whether this is a good thing depends on the situation.

"What the earthworms do and how we value it is what really matters." said Hale. "In one place-farm fields or gardens-we really like European earthworms and what they do, so we consider them good. In native hardwood forests, we really don't like what they do-so we consider them bad. You really have to understand how an organism(微生物) affects an ecosystem. Things aren't black and white."
