2 . If you ever get the impression that your dog can “tell” whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.

Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by showing them the other half of the person’s face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.

The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth,” said study author Corsin Muller. “Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”

“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Muller told Live Science.

At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. “To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, and this exposure has provided them with many chances to learn to distinguish between them,” Muller said.

5 . Peer ( 同伴 ) Assisted Study Sessions (PASS) is a peer-facilitated learning programme available to students enrolled ( 注册 ) in most core units of study in our business school.

PASS involves weekly sessions where you work in groups to tackle specially prepared problem sets, based around a unit of study you’re enrolled in.

PASS doesn’t re-teach or deliver new content. It’s an opportunity to deepen your understanding of the key points from lecture materials while you are applying your skills to solve problems.

You work interactively with your peers. As a peer group, you decide what is covered in each session. That way, PASS directly responds to your needs and feedback.

Registration in Term 2 will open at 9 am, 21 September 2022.

Waiting lists

If a session is full, you can register for the waiting list. We will email you if a place becomes available or if a new session is to be held.

When you are placed on a waiting list, we will email you a number which tells you where you are on the list. If you are close to the front of the list, you have a good chance of gaining a place in the programme in the near future.

Deregistering

If you miss two PASS sessions in a row, you will be deregistered and your place will be given to someone on the waiting list. Make sure you fill in the attendance sheet at each session to record your attendance.

You’ll be informed by email if you are being deregistered as a result of missing sessions. If you believe you have received the email in error, email the PASS office at   passoffice@umbs. edu..

6 . Parrots are prey animals, which means that other predators (捕食者) in the wild, such as hawks or snakes, are looking to make them into a meal. This one factor influences parrots’ behavior in your house more than any other.

Parrots are most easily hurt when feeding on the ground. Membership in a group plays an important function in ensuring their safety and improving their chances of survival from attacks by predators. The most common predators of parrots include hawks, snakes, cats, monkeys, and bats. Some predators make attacks only during the day while others hunt in the night.

As prey animals, parrots are constantly watching out for danger and they instinctively (本能地) react to risks. Their first choice is to take flight. However, if this is not possible, they will fight with their powerful beaks to defend themselves.

Because their biggest enemy is the hawk, parrots are especially reactive to quick movements from above and behind. For this reason, it is wise to avoid quick, sudden movements near your bird. This is a built-in reaction not subject to logic or reason. Simple and relatively harmless household objects can draw extreme fear responses from a bird. For example, a balloon may represent a hawk or a vacuum hose (吸尘器软管) may be the same as a snake in your bird’s mind.

As prey animals, parrots are often frightened by exposure to new household items or strangers. It is important to expose your bird to safe experiences and changes starting at a very young age to build flexibility and improve their adaptability. Variety in diet and toys, travel, and exposure to new people and places all help to make your bird more flexible and adaptable to change.

7 . Yellowstone Poster Exhibition to Be on View at UW’s Coe Library

A first-of-its-kind exhibition that focuses on the history of Yellowstone National Park posters will be on display at the University of Wyoming’s Coe Library beginning Tuesday, February 1.

“Wonderland Illustrated” will present posters and poster-style illustrations of the park spanning from the 1870s through 2022. The exhibition will be located on Level 3 of Coe Library. It will be on view through Tuesday, May 31.

The exhibition takes place at the same time as this year’s 150th anniversary of the creation of Yellowstone National Park. The posters in the exhibition serve the purpose of both advertising and art.

“We’re thrilled to be working with Yellowstone collectors Jack and Susan Davís, and Larry and Thea Lancaster to bring this exhibition to the University of Wyoming as part of year-long celebrations recognizing Yellowstone’s 150th anniversary,” says Tamsen Hert, head of UW Libraries’ Emmett D. Chisum Special Collections. “This exhibition involves the history of printing, art, photography and advertising over 16 decades. The images reproduced are found on travel brochures, postcards and maps—many of which are held in our collections.”

One poster from the exhibition—Henry Wellge’s “Yellowstone National Park” from1904—was recently purchased with donated funds and is now part of UW Libraries’ Emmett D. Chisum Special Collections. Wellge, a productive bird’s-eye-view artist, designed the piece for the Northern Pacific Railroad, which used it to advertise the park. This is a unique piece, as posters such as this one were printed on soft paper and very few have survived.
