Researchers at the University of Helsinki recently examined hyperactivity (过分好动) and inattention in more than 11, 000 Finnish pet dogs. They found that the dog’s age and gender, as well as exposure to other dogs, played a part.
“We wanted to collect a large behavioral data of dogs to better understand behavior problems that are common in our companion dogs. We studied seven characteristics: noise sensitivity, fearfulness, fear of surfaces and heights, inattention, compulsive behavior, separation – related behavior, and aggression,” says Sini Sulkama, a researcher at the University of Helsinki.
Their goal was to identify demographic (人口统计的), environmental, and behavioral risk factors that could influence these anxiety - related characteristics in dogs. Their analysis showed that hyperactivity, impulsivity, and inattention were more common in young dogs and male dogs. They also found some major differences among breeds.
Interestingly, researchers discovered that the owner’s experience with dogs also had an impact. They found that hyperactivity and impulsivity are more common in dogs that aren’t their owners’ first dogs. “We can only conclude the possible relationship between these factors, but one possible explanation is that people try to choose easy individuals from less active breeds, like companion dog breeds as their first dogs,” says Sulkama.
They also calculated the urban environmental score for each dog. That describes how the land is used around the dog’s current home, breaking it down into artificial surface, agricultural areas, forests, and semi natural areas.
Although it might seem like most dogs are easily distracted to some extent, studies suggest that about 15% of dogs display high levels of hyperactivity and 20% show high levels of inattention. Researchers say they can make it easier to identify and treat dogs’ hyperactivity and inattention and may benefit the research. They can also be helpful when choosing to add a dog to the family. You might want to adopt a pet with the characteristics of a breed that matches your lifestyle.

Can Skipping Dinner Help You Lose Weight?
If your phone needs a software upgrade, you would likely run the operation when its fully charged.
Specifically, people who eat larger breakfasts and adopt an 18-hour overnight fast, say from 1 pm to 7 am, have the lowest body weights.
Contrary to the popular belief, these extended overnight fasts seem to help increase metabolic function. Lead author Dr Hana Kahleova finds meals consumed in the evening, compared to those eaten in the morning, result in higher blood sugar, which happens when insulin cannot process glucose into energy.
A.Of course, this approach isn't for everyone. |
B.So, let's say you consume 1,500 to 1,800 calories a day. |
C.Those who ate later in the day, after 6 pm, had higher body weights. |
D.Otherwise, your phone and its software would take longer to sync. |
E.This means eating a larger breakfast, a medium-sized lunch and no dinner. |
F.Like a block in a machine extra glucose slows our metabolic process down. |
G.The advice to eat breakfast like a king, lunch like a prince and dinner like a beggar has new science behind it. |
Knowledge might be power, but it’s much more powerful when it’s shared! If only one person knows how to do something, that prevents others from developing and can prevent your organization’s progress. Plus, what happens if they hoard (储藏)knowledge and decide to leave your company? When you manage knowledge properly and give people a platform to share and access it, you’re opening the door to a whole host of benefits!
It’s important to clarify the difference between knowledge and information before diving into the benefits of knowledge sharing. Information is really just the data or details of something, but knowledge taps into the experience and context of somebody who’s understood and used that data. Imagine you’re making a cocktail and you’ve got the ingredient list in front of you, you’d be able to attempt some shaking and pouring. But, without a recipe or guidance from somebody who’s trialed, errored and perfected, you wouldn’t know the order, the timings and the techniques needed. Knowledge sharing makes sure your employees are less shaken and more inspired.
If knowledge isn’t shared, people take it with them when they leave-and no company has time to relearn the things they once knew. But if your experts are sharing knowledge with peers, they’re gaining relevant, company-specific information-which allows you to build collective intelligence. The act of sharing knowledge alone is great for building relationships, where people get that warm feeling from either sharing their wisdom or picking up on the wisdom of others. But it’s more than that-developing a knowledge-sharing culture allows you to tap into experts! Across the business, people will have built skills and best practices that are specific to your product and customer. When they share those experiences, they allow others to skip the trial period and get right to productivity.
The more you encourage that behavior, the more an organic learning culture builds throughout the team! This means all the benefits we’ll dive into are happening day in and day out.

How did you develop from an infant(婴儿),with a few elementary thinking skills, to the adult you are now, with the ability to reason and analyze the world in many complex ways involving language, symbols and logic? Your first reaction to this question may be very likely to say, “Well, I learned how to think from my experiences and from the teaching I received from adults through my life.”
Although this explanation seems naturally correct to most people, many developmental psychologists believe that much more is involved in acquiring intellectual abilities than simple learning. The current view about intellectual development is that it is a process of maturation, much like physical development, that occurs in a predictable fashion from birth through adulthood.
Do you look at an infant and see a person who, with enough learning, is capable(有能力的) of adult physical behaviors? Of course not. Instead, you know that the child's behavior will become increasingly complex over time through a process of physical maturation. You know that until the child achieves a certain level of development, all the learning in the world cannot produce certain behaviors. For example, consider the behavior of walking. You probably think of walking as a learned behavior. But imagine trying to teach a 6-month-old to walk. You could place the infant on an Olympic-level schedule of 8 hours practice every day, but the child will not learn to walk, Wily? Because the child has not yet reached the physical maturity to perform the behaviors needed to walk.
Intellectual development occurs in much the same way. Children simply cannot display certain thinking and reasoning abilities until they reach an appropriate stage of intellectual development, no matter how much learning they may have experienced.
