What if our babies could somehow tell us what they're thinking about, what they want, and what makes them unhappy? Robyn Holt, researcher for Baby Talk New Zealand, says they can. Holt heard about baby sign language through an advertisement and decided to go along to a workshop (研讨会).

    “Sign language is something that's always interested me, and I thought, it could be really cool to try this with a baby because we are always guessing all the time what they actually want.”

    Holt started using baby sign language with her baby son Benjamin, now 12, and within two weeks he started to sign the sign for milk. She has since used it with her two younger sons Dominic, 8, and Matthew, 3.

    Baby sign language is nothing new: the practice (which is based on adult sign language) has been out in America for more than 30 years. But it is enjoying a rebirth in New Zealand.

    The idea behind baby sign language is that babies do have the ability to communicate their needs if they are given the right tools to do so. Although many mothers develop an intuition (直觉) about whether their baby's crying is from hunger, tiredness, or pain, baby sign language creates a direct form of communication that unlocks the mystery.

    When babies are between 6-months and 12 to 13-months, parents can begin to teach them sign language: use the sign for milk while feeding, and also talk about milk, so that the child begins to make the link (关联) in their brain. Then they can begin to add other signs, i.e. food, sick or pain.

    “I know of one parent. Her child was signing the sign for hurt by his mouth, and she realised his first teeth were growing. It makes life so much easier,” said Holt.

    What is it?

    KindSpring has created a series of 21-Day Challenges designed to help individuals and groups grow in values that help create positive change. Regardless of profession, age, culture or geography, when we try to cultivate(培养) certain values we create a ripple effect(连锁反应) that has the power to transform our lives and the world for the better. When we practice these values together over and over again, our efforts encourage and strengthen each other in remarkable ways. Each of our 21-Day Challenges focuses on a specific value — from kindness to mindfulness. Click here for more information.

    How does it work?

    A small daily commitment + a daily prompt(提示)+ a process for communication. Each 21-Day Challenge invites participants to carry out one small daily action related to the main theme. Every day for three weeks a unique idea is emailed out that serves as a prompt. Participants are encouraged to carry out the act and share stories of their experiences in both online and offline spaces. You can sign up to participate as an individual or you can “host” a challenge for a group you belong to. The challenges were developed for workplace, school/college and family environments, but are broadly usable. Any group is more than welcome to take them on. At the end of 21 days, you may continue the practice with your group, take on a new challenge, or even design your own. There is no charge for any of our services. All the challenges are offered as a gift. Five steps to host a challenge.

    Why should we do it?

    The 21-Day Challenges are all designed to fit the pace of modern day life. They are not very time-consuming（耗时的）, and in most cases demand less than five minutes a day. Twenty-one days certainly can't change everything, but it can begin a new way of being. You are invited to bring these practices to your company, school, community center, or family. Get started with joining a challenge or hosting one here. Let us know if you have questions—we're delighted to help any way we can!

    In the years of my growing up, Dad was hard on me. He made sure I made my bed and did my homework. As a school girl and young adult, I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A's and unhappy with my boyfriends if their fathers were not as "successful" as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

    He would call in advance to make sure there was no alcohol(酒精) at the party. I got so angry with him for laying down the law. I would scream, "I hate you!" Dad would yell back, "Good! I don't care!" Deep down I knew he did.

    One time at a party, I drank too much alcohol and got so sick. I said, "Call my dad." Next thing, Dad was carrying me to the car. I woke up the next morning, thinking I would definitely be criticized(批评). As expected, I got a roasting, but I now understand why I need discipline(纪律).

    Dad was 29 when he got his big roles in films. I had an early start at the age of nine with a role in a 1990s TV series, but it wasn't until I finished film studies that I pursued my career as an actress. Like those early days for Dad, I faced lots of rejections. Working in such a competitive industry, I've sometimes thought, "I can't do this any more."

    Once, after a trip to Hollywood, I returned to Australia so depressed and spent months in my bedroom painting, listening to Eckhart Tolle's music and trying to find myself again. Dad sat me down and said, "Alice, I know it's hard, but it's all about persistence(坚持不懈)."

    Now I get to work with Dad a lot, which I love. We are both enthusiastic about acting, which comes from us being so interested in people. If it weren't for Dad, I wouldn't be where I am today. He's my biggest fan, and when you have that in your life you can go a long way.

    A new study by the British government has discovered the mental well-being of the country's teenage girls has worsened.

    The survey, which included 30,000 14-year-old students, showed 37 percent of the girls with psychological stress, rising from 34 percent in 2010. British boys' stress level was actually seen to fall over the same period, from 17 percent to 15 percent. The report's authors pointed out the "arrival of the social media age" could be a major contributing factor for increasing stress among teenage British girls.

    "The adolescent years are a time of rapid physical, cognitive and emotional development," Pam Ramsden, a lecturer in psychology at the University of Bradford in the United Kingdom, wrote in a recent blog post. "Teenagers interact with people in order to learn how to become competent adults. In the past, they would engage with parents, teachers and other adults in their community as well as extended family members and friends. Now we can also add social media to that list of social and emotional development." Throughout adolescence, girls and boys develop characteristics like confidence and self-control. Since teenage brains have not completely developed, teens don't have the cognitive awareness to keep from posting inappropriate content. Furthermore, this content can easily be circulated far and wide with disastrous implications.

    "Social media can also feed into girls' insecurities about their appearance," Ramsden said. These sites are often filled with images of people with body type unattainable to the normal person. However, these images and the messages tied to them creep into social standards.

    "Social media allows girls to make comparisons among friends as well as celebrities and then provides them with 'solutions' such as extreme dieting tips and workouts to reach their goals," Ramsden said. "Concerns about body image can negatively impact their quality of life preventing them from having healthy relationships and taking up time that could be better spent developing other aspects of their personalities."

    My elephant adventures began in 1984 when, with our one-year-old daughter, my husband and I crossed the jungle in a jeep, slicking behind a lorry for comfort and company. The elephants standing like watchers on either side of the forest highway had us praying for our safety. One elephant made loud noise and angrily pawed (抓) the ground, warning us off. We raced away before they could attack.

    It was wise to keep elephants at a distance. We heard stories of tourists whose jeeps were overturned, and a couple of photographers were killed because they moved too close. Elephants are misleading animals. They give people an impression of being quiet and kind, so tourists think it's safe to picnic in the jungle (丛林). Yet angry elephants have knocked them down in seconds before they could take off.

    Elephants might make life unpredictable and dangerous. It's difficult for inexperienced environmentalists to even, begin to grasp this reality. I've heard city people say " We humans are encroaching (侵害) on their forests." But what's the solution?

    When a poor farmer borrows heavily to plant a crop, he'll do anything to protect it His life depends on it Elephants ruining an about-to-be-harvested corn field cannot expect to be welcomed like special guests. The battle between beast and farmer is violent.

    Experts are working on solutions to human-elephant conflicts (冲突). Some are sure to fail to like the plans to build electric fences around human settlements. Elephants rapidly figure them out and come in, around and over them.

    There are more questions than answers, for sure. But as my husband said, "More people die in car accidents every single day, in every city on the earth. But they won't take cars off the roads, will they?" So we need to seek practical ways of preventing elephant accidents.

    A new study suggests some language learning can take place during sleep. Researchers from Switzerland's University of Bern say they discovered people were able to learn new language words during deep levels of sleep.

    Much of the earlier research found that memories made when awake were strengthened during sleep. This supported the idea that information learned while awake is replayed and deeply embedded in the sleeping brain.

    The researchers theorized that, if replay during sleep improves the storage of learned information while awake, the processing and storage of new information should also be possible during sleep.

    They carried out experiments on a group of young German­speaking men and women, which centered on periods of deep sleep called "up­states". They identified these slow­wave peaks as the best moments for sleep­learning.

    The researchers observed individuals in a controlled environment during brief periods of sleep. Brain activity was recorded as pairs of words were played for the study subjects. One word in the pair was a real German word. The other was a made­up foreign word. For later identification purposes, the German words chosen were things clearly larger or smaller than a shoebox.

    Each word pair was played four times, with the order of the words changed each time. The word pairs were played at a rhythm that is similar to actual brain activity during deep sleep. The goal was to create a lasting memory link between the false word and the German word that individuals could identify while awake.

    When the subjects woke, they were presented with the false language words­both by sight and sound. They were then asked to guess whether the false word played during sleep represented an object smaller or larger than a shoebox. Results of the study found that a majority of subjects gave more correct answers about the sleep­learned words than would be expected if they had only guessed at random.

    The researchers said they measured increased signals affecting a part of the brain known as the hippocampus. This brain structure is very important for building relational memory during non­sleep periods. The researchers also said memory was best for word pairs presented during slow­wave peaks during sleep.

    The study suggests that memory formation in sleep appears to be caused by the same brain structures that support vocabulary learning while awake. The researchers say more studies are needed to support their findings. However, the experiments do provide new evidence that memories can be formed and vocabulary learning can take place in both conscious and unconscious states.
