A research has shown that nearly 90 percent of traffic accidents are caused by human errors. So our aim is a fully autonomous car that gets rid of the cause of most accidents: the driver. Researcher Hodgson points out, “For safety, the faster you can remove humans, the better, even if there are unfortunately a few accidents from new causes. It s a question of balancing the number injured or killed by autonomous vehicles with the people whose lives are potentially saved.”

It's an idea that Elon Musk, chief executive of electric car company Tesla Motors, has long believed. His company are determined to be the first to deliver a fully autonomous vehicle to consumers. Last year, Musk announced that Tesla's 2017 goal was “to do an example drive of full autonomy all the way from LA to New York…and have the car park itself.”

However, even Tesla admits that there are problems to overcome—the software needs further validation and the appropriate regulatory approval needs to be in place. Indeed, recent crashes of Tesla vehicles and Google cars confirm that the software isn't ready yet.

The UK government appears committed to encouraging the development of autonomous vehicles. It's supporting four city trials, publishing the Modem Transport Bill to reduce red tape around their introduction and adapting the legal system to take into account problems such as insurance liability when a human isn't in control of a vehicle.

    The insurance industry is similarly eager to help increase autonomy in cars. As the Association of British Insurers (ABI) points out, “More than 90 per cent of road accidents are caused by human error.” This costs motor insurers a shocking £20m per day in claims.

    Move over millennials(千禧一代), here comes Generation Z, today's youngest group.

    Born in 1995 or later, a lot of Gen Z-ers are entering into adulthood and will soon join the workforce. People of Generation Z have grown up with the internet. Policy makers, sociologists, as well as employers and marketers, are trying their best to understand these young people. So, how should we pin down the Gen Z-ers?

    Most people will agree that the single biggest difference between Gen Z and other generations is how connected they are. This is a group of people who were hooked up to social media as soon as they were born. A recent Guardian article says that the average teenager in the UK has at least 150 followers on Instagram and spends around half an hour a day on Snapchat, an image messaging app. “We are the first true digital natives,” Hannah Payne, an 18-year-old UCLA student and lifestyle blogger. “I can almost create a document, edit it, post a photo on Instagram and talk on the phone at the same time, all from the user-friendly interface(界面) of my iPhone.

    The Guardian also notes that young people in the UK are becoming more active in politics. Voting is just one way of making one's voice heard. Most of Generation Z are still too young to vote, says the Guardian. Instead of party politics, they focus more on single-topic issues such as feminism(男女平等)or climate change. And “much of the civil engagement and organizing they do takes place on social media rather than through traditional political structures,” according to the newspaper.

Evening Workshops

    Optional evening workshops will be held at small restaurants or other meeting places near the conference hotel. Meals and other costs are not included but are also optional. Locations will be announced at the conference site. Workshops are very loosely organized and most represent discussions that have been held at Society for Economic Botany (SEB) meetings over a series of years.

    Workshop 1: Student Network

    Date: Wednesday evening, Feb. 5^th

    Chairs: Hugo de Boer and Arika Virapongse Sponsor: Society for Economic Botany

    Description: Student members of the SEB hold a networking mixer each year in order to meet each other and to become familiar with a variety of educational programs and faculty advisors(大学指导老师). Faculty members who are part of training programs are encouraged to join the mixer to meet and talk with students.
     Workshop 2: Botanical Film Making
    Date : Wednesday evening, Feb. 5^th Chair : David Strauch

    Sponsor : University of Hawaii

    Description : Digit al film making is a particularly useful tool of linking cultural information to recognizable plants. This workshop is aimed towards increasing the quality of material recorded by giving participants greater control over the medium. We will cover technical aspects (e.g. camera settings, audio), technical aspects (framing, lighting, focus), and some ways of presenting the material. Experienced filmmakers are encouraged to attend, and participants are welcome to bring their own camera equipment.

    Workshop 3: Collections for Botany

    — Collections Development and Management Date: Friday evening, Feb. 7^th

    Chair: Jan Salick

    Sponsor: Society for Economic Botany

    Description: SEB is a network of researchers who have been developing standards for the development of collections of artifacts, plant samples and related materials. Participants discuss successes, problems, and funding sources for solving management issues.

Plastic sludge (污泥) and garbage is a disaster for the world's oceans. A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. "Half of the waste actually sinks to the bottom, and that remains on the surface actually breaks down. "

The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacific Oceans, home of what some have plastic. "What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant. "

The pieces of the plastic garbage infect the food chain, sometimes visibly，and more so at the microscopic level, where the plastic particles interact with other pollutants. "There are heavy metals, medicines, industrial waste in the sea, while they acts like magnets (磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues. " To be consumed by other sea life and by people at last.

China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters. The United States, although a leader in recycling, is one of the world's 20 since it produces and consumes so much plastic. There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon (黎巴嫩). But Andersen says there is more that people can do. "Cut back on single­use plastics, straws, plastic cups, plastic water bottles, plastic bags and find alternatives like reusable materials. " She says healthy oceans are essential to our survival.

My clder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult.

For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had scared through Mrs. Holt's basement window, breaking the glass with a crash, Steve encouraged me to confess(认罪) to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball.

I also learned from Steve that personal property is a sacred(神圣的) thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I'd hate to lose to someone else the small dog my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on my shoulder.

Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind. When I was twelve I killed an old brown sparrow in the yard with a BB gun. Excited with my accuracy. I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, "Did it hurt you first, Mark?"I didn't know what to answer. He continued with his eyes firm," The only time you should even think of hurting a living thing is when it hurts you first. And then you think a long. long time." I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.
