Don't Drop the Ball

    Drop prevention risk assessment is really important. Everyone knows objects get dropped on work sites – there's nothing radical about that. In Australia, mining has the third highest fatality rate of any industry (4.4 fatalities per 100,000 workers in 2015), and in less well-documented areas like India the fatality rate is even higher. A lot of these fatalities come from dropped objects. It's worth trying to address this and work out just how big the risk is and where it comes from. At the end of the day, safety should be a priority in any industry and it should come as no surprise that addressing safety issues early can actually save money, long-term, for companies. It doesn't look good for a mining company if people are getting injured and equipment damaged from falling objects.

    The risks from dropped objects come from all sorts of areas; it's not just a matter of dropped tools. We're talking about sites characterized by a lot of activities, where all sorts of things can come loose or fall, whether its light fittings or objects like rocks falling off transporting belts. The risks are largely personal but are also financial: if a piece of equipment gets damaged it will need replacing. That's a pretty strong inspiration for companies to address these risks. In terms of frequency, here in Australia we're looking at around 18% of compensation claims coming from workers being hit by moving objects, but those are just the claims – the frequency is likely higher. Around 28% of deaths and injuries come from such incidents, too. As I said earlier, that's just Australia; some industries don't keep statistics, but I wouldn't be surprised to find other countries report comparable rates. That's a lot of accidents that could be prevented with adequate safety measures.

    It's important to take an active approach. It's a lot easier and cheaper to address these risks during the installation or maintenance phases by adding barriers to the inside of guard railings on walkways and transporting systems and adding nets to fixed devices. There are safety mechanisms available, but it's up to the companies to install them. It is a lot more efficient to add barriers right from the start rather than waiting for an accident and then thinking, "Should we be safer?", when they should have reduced these risks from the start.

    What a day! I started at my new school this morning and had the best time. I made lots of new friends and really liked my teachers. I was nervous the night before, but I had no reason to be. Everyone was so friendly and polite. They made me feel at ease. It was like I'd been at the school for a hundred years!

    The day started very early at 7:00 am. I had my breakfast downstairs with my mom. She could tell that I was very nervous. Mom kept asking me what was wrong. She told me I had nothing to worry about and that everyone was going to love me. If they didn't love me, Mom said to send them her way for a good talking to. I couldn't stop laughing.

    My mom dropped me off at the school gates about five minutes before the bell. A little blonde (金发的) girl got dropped off at the same time and started waving (招手) at me. She ran over and told me her name was Abigail. She was very nice and we became close straight away. We spent all morning together and began to talk to another girl called Stacey. The three of us sat together in class all day and we even made our way home together! It went so quickly. Our teacher told us that tomorrow we would really start learning and developing new skills.

    I cannot wait until tomorrow and feel as though I am really going to enjoy my time at my new school. I only hope that my new friends feel the same way too.

    A traveller was staying in an Egyptian village. One day, she held up her camera to take pictures of the children. Suddenly the young ones began to shout at her. The traveller's face turned red and she apologized to the head for what she was doing, and told him she had forgotten that people in some places believed a person would lose his soul(灵魂) if his picture was taken. She explained to him the operation of a camera for a long time. Several times the head tried to say something, but he couldn't. When she believed that the head didn't fear any longer, the traveller then let him speak. With a smile, he said, "The children were trying to tell you that you forgot to take off the lens(镜头) cap!"

After a long and hard journey that made international headlines, China's famous herd of wandering elephants appears to finally be heading home.

In August, the 14 Asian elephants of various sizes and ages were guided across the Yuanjiang river in Yunnan and a path was being made for them to return to the nature reserve in the Xishuangbanna Dai Autonomous Prefecture.

The elephants' return completes a more than 500km odyssey that caught the attention of the country. The highlights of their trip included the birth of a calf in Pu'er in last November; and going viral for taking a nap. If they were just taking a walk in the forest, it wasn't a big deal. But the fact is, they left whatever they stepped on in ruins, causing great damage to local residents.

Local wildlife experts have been unable to pinpoint the reason the herd decided to move. One reason is given that the population of elephants in the nature reserve in the Xishuangbanna Dai Autonomous Prefecture is so large, which has increased from 190 to over 300 since 40 years ago, that there is not enough food for them. Some say that their move is due to the influence of the magnetic field of the earth and there is another story saying maybe that lead elephant lost its way, thus leading the herd out of the way. But Zhang Li, a professor on conservation biology at Beijing Normal University, told the Global Times in June that large-scale human engineering developments have sped up the ‘islanding'of elephant habitats.

This meant "the traditional safe zones between humans and elephants are gradually disappearing, and the chances of elephants encountering humans naturally increase greatly".

Traditionally, businesses use name badges(胸卡) for security and personal identity; the whole look also contributed to brand identity. But the use of name badges has so much more to offer: 

{#blank#}1{#/blank#}Name badges complete the overall look of an employee. Businesses who carry out this practice show that they pay attention to detail, no matter how small, giving the staff a professional look. Customers are more comfortable dealing with someone who looks professional and well trained. 

Name badges give employees identity. Name badges can make employees feel better about their jobs because they are not just nameless people. Name badges also promote a friendly environment, which leads to happier employees. {#blank#}2{#/blank#} Furthermore, the knowledge of being easily identified also makes an employee perform better, lest(以免) they be reported for bad service.

Name badges promote communication. {#blank#}3{#/blank#} This allows for easier communication, and employees are able to assist customers better when they know exactly what the customer wants or needs. A name can certainly make a big difference, not just for overall customer experience, but for the business as well. 

Name badges lend an air of familiarity. Customers are more comfortable when they know who they are speaking to or who is assisting them. Employees may also be required to find out the customer's name, all in the spirit of providing personalized service. {#blank#}4{#/blank#}

Name badges keep security in check. While name badges can keep businesses secure by identifying that the right people are where they should be, they also make customers feel secure by knowing who they are dealing with. {#blank#}5{#/blank#}

A．Name badges come in different colors and styles.

B．Name badges make employees look more professional.

C．Satisfied employees, in turn, deliver better customer service.

D．It's easier to talk to someone when you can address them by name.

E．In companies using name badges, the employees are more efficient.

F．Customers won't risk mistaking another customer for a member of the staff.

G．As a result, name badges make employees more approachable and business smoother.

When it comes to architectural accomplishments, humans like to think they stand at the top. That is to underestimate the astonishing achievement s of social insects; for example, white ants raise skyscraping nests. The true master builders of the insect world, however, are the hundreds of species of stingless bees.

In a new study, Ms. Di Pietro and her colleagues observed over 400 colonies of the stingless bee species in a large bee house in Brazil in 2022 and 2023. Around 95% of the colonies exhibited honeycombs（a structure made by bees） built up in horizontal layers（水平分层）, like tiered wedding cakes, while the rest adopted a spiral（螺旋的） structure.

Since the stingless bee shows a strong preference for a horizontal-layer honeycomb structure, it's surprising that spiral honeycombs occur. The team confirmed that there was no difference in the average cell-building rate between the two styles, and therefore no efficiency advantage.

In order to rule out a genetic explanation for the different styles, the researchers transplanted workers from colonies that built in one tradition to colonies that built in the other, having first emptied the host structures of their native adults. The imported workers soon switched to the local style, which was then continued by the colony's young insects as they eventually matured into workers.

Dr. Tom Wenseleers guessed that the bees may switch styles as a way of coping with the build-up of small construction errors made by their fore-runners. Such a process, in which multiple organisms indirectly affect each other's behavior through the traces they leave in their environment, is known as stigmergy（共识主动性）. The researchers later introduced a sign of spirals to the otherwise perfect horizontal-layer honeycombs, and found that it did indeed cause the bees to switch to building spirals.

These results suggest that stingless bees can pass on different building traditions across generations and individuals needn't be instructed by their peers. "The findings are the clearest demonstration of cultural differences naturally appearing in insects. Insect culture would once have been thought impossible," says behavioral biologist Andrew Whiten, who wasn't involved in the research. "Less than a century ago, culture was thought to be uniquely human."
