资料：Placing the right type of workers in close proximity to each other can generate up to a 15 percent increase in organizational performance，according to the study from Cornerstone On Demand，a provider of cloud-based learning and talent-management software，and researchers at Harvard Business School in Massachusetts. For businesses with 2，000 employees, this translates into an additional $1 million in profit each year，the study said.
For the study，researchers examined data from a two-year period of more than 2，000 employees working at a large technology company with locations in the U.S. and Europe. The study’s authors separated workers into three different categories based on the work they produced：
Productive： These employees are very productive，but don’t always produce quality work.
Quality：These workers produce work of superior quality，but aren’t always productive.
Generalists： These employees are average in terms of both productivity and quality.
The researchers defined productivity by how long it takes an employee to finish a task，and effectiveness by how often employees need to ask a co-worker for help completing a task.
What is NOT true about the categories of the workers？

If you use your commute to catch up on work email, that time "should be counted as part of the working day," according to a new study by researchers who analyzed thousands of commuters'online habits." If travel time were to count as work time, there would be many social and economic impacts." said Juhet Jain, one of the academics from the University of the West of England who surveyed several thousand commuters on trains in and out of London.
"Most respondents expressed how they consider their commute as time to 'catch up' with work, before or after their traditional working day," according to a summary of the study.“This transitional time also enabled people to switch roles, for example from being a parent getting the kids ready for 3 school in the morning to a business director during the day " The study quotes a working mother named Katheryn saying. "It's really important to my sanity that I can get work done on the tram. I am a busy mum and I rely on that time, so I can get things done”Another commuter, Andrew, told the researchers.'“It's dead time in a way so what it allows me to do is finish stuff and not work in the evenings." The study notes that while work rules vary around the world, some commuters in Norway are already "able to count travel time as part of their working day”
The findings on workers' use of smartphones and other devices to stay plugged in highight the importance of providing Wi-Fi to commuters, according to the academics, who presented their study at the Royal Geographical Society. To ollet the data, they focused on two train lines that boosted the amount of free Wi-Fi they offered. On the Birmingham to London line, 60 percent of commuters connected to the enhanced network. The results hint at what are likely to be increasingly complicated work-life discussions, in which employees and their bosses debate what qualifies as "work" and where the line between personal and professional time should be drawn. Discussing the results in a news release, Jain said, "It may ease commuter pressure on peak hours and allow for more comfort and flexibility around working times. However, it may also demand more survillance and accountability for productivity."
In addition to potential ramifications for mass transit that the British researchers highlighted,the idea of claiming commuting time on the clock could also appeal to workers who use other means of travel. Take, for instance, people who rely on ride. share companies to get to their jobs. And the discussion seems certain to widen in the near future, to inc lude a looming wave of self-driving cars that - in theory, at least -promises to free up more travel time for drivers.
As for rail commuters, the researchers said their work shows it s important that trains "“ffer a good working environment including tables , power。space and good continuous connectivity for internet and phone calls"

You have been badly injured in a car accident．It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident．However,special care must be taken in selecting new blood for you．If the blood is too different from your own,the transfusion could kill you.
There are four basic types of blood;A,B,AB and O．A simple test can indicate a person's blood type．Everybody is born with one of these four types of blood．Blood type,like hair color and height,is inherited from parents.
Because of substances contained in each type,the four groups must be trans fused carefully．Basically,A and B cannot be mixed．A and B cannot receive AB,but AB may receive A or B．O can give to any other group,hence it is often called the universal donor．For the opposite reason,AB sometimes called the universal recipient．However,because so many reactions can occur in transfusions,patients usually receive only salt or plasma until their blood can be matched as exactly as possible in the blood bank of a hospital．In this way,it is possible to avoid any bad reactions to the transfusion.
There is a relationship between your blood type and your nationality．Among Europeans and people of European ancestry,about 42 percent have type A while 45 percent have type O．The rarest is type AB．Other races have different percentages．For example,some American Indian groups have nearly 100 percent type O.
If you need a transfusion,the best and safest blood for you is__.

Don't Be Workaholic
Workaholic and working hard are quite different.
Working hard involves being organized,focused,getting a lot of work done,knowing when to stop,and having a life other than work.Workaholics,on the other hand,are often disorganized,always find reasons for working more,feel lost without work to do,hide from problems through work, don't know how or when to relax,bring work home from the office,can't communicate well with fellow workers and family members and have unbalanced,one-dimensional lives.
Workaholics,like those who are constantly drunk,suffer from a controlling habit,usually defined as compelling behavior despite negative consequences.They are sometimes pushed into their habit by their work beliefs,by workaholic role models,and by a work system that automatically sanctions workaholism,Despite lip service to the contrary,most employers want loyal employees who work longer hours,rewarding them with higher pay and better benefits.In many companies,workers unwilling to burn the midnight oil are at risk.Certainly,they hazard their jobs by working normal hours.Americans tend to become trapped in a working and spending consumption mode,driven by merchants,that leads them to rack up their expectations.
According to some psychology counselors,workaholism can be both good and bad for us.It can fuel a sense of self-worth and accomplishment. And we get paid for it and praised for it,which produces good feelings we may not necessarily be able to attain in other parts of our lives.

Smart Exercise
Doctors are starting to find more and more information that suggests a connection
between exercise and brain development.Judy Cameron,a scientist at Oregon Health and
Science University,studies brain development.According to her research,it seems that
exercise can make blood vessels,including those in the brain,stronger and more fully
developed.Dr. Cameron claims this allows people who exercise to concentrate better. As
she says:"While we already know that exercise is good for the heart,exercise can literally
cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies.Babies who
do activities that require a lot of movement and physical activity show greater brain
development than babies who are less physically active.With babies,even a{ittle
movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in
the importance of exercise.She thinks that many learning disabilities that children have in
elementary school or high school can be traced back to a lack of movement as babies.
"Babies need movement that stimulates their five senses.They need to establish a
connection between motion and memory.In this way,as they get older,children will begin
to associate physical activity with higher learning,"says Margaret.
Older people can beef up their brains as well.Cornell University studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term
memory increase of up to 40 percent after exercising just three hours a week.The exercise
does not have to be very difficult,but it does have to increase the heart rate.Also,just like
the motion for infants,exercise for older people should involve some complexity.Learning
some new skills or motions helps to open up memory paths in the brain that may not have
been used for a long time.
For most people,any type of physical activity that increases the heart rate is helpful.
The main goal is to increase the brain's flow of blood.And your brain can benefit from as
little as two to three hours of exercise a week.
