Population Change
Why is the world's population growing?The answer is not what you might think. The reason for the explosion is not that people have been reproducing like rabbits, but that people have stopped dropping dead like flies. In 1900,people died at the average age of 30.By 2000 the average age was 65.But while increasing health was a typical feature of the 20th century, declining birth rate could be a defining one of the 21st.
Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays. Furthermore, around 50% of the world's population live in regions where the figure is now below the replacement level(i.e.2.1 births per woman)and almost all developed nations are experiencing sub-replacement birth rate. You might think that developing nations would make up the loss(especially since80% of the world's people now live in such nations),but you'd be wrong, Declining birth rate is a major problem in many developing regions too, which might cause catastrophic global shortages of work force within a few decades.
A great decline in young work force is likely to occur in China, for instance. What does it imply? First, China needs to undergo rapid economic development before a population decline hits the country. Second, if other factors such as technology remain constant, economic growth and material expectations will fall well below recent standards and this could invite trouble.
Russia is another country with population problems that could break its economic promise. Since 1992 the number of people dying has been bigger than that of those being born by a massive 50%,Indeed official figures suggest the country has shrunk by 5% since 1993 and people in Russia live a shorter life now than those in 1961.Why is this occurring? Nobody is quite sure, but poor diet an above all long-time alcoholism have much to do with it. If current trends don't bend. Russia's population will be about the size of Yemen's by the year 2050.
In the north of India, the population is booming due to high birth rates, but in the south, where most economic development is taking place, birth rate is falling rapidly. In a further twist, birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas. In total,25% of India's working-age population has no education. In 2030,a sixth of the country's potential work force could be totally uneducated.
One solution is obviously to import foreign workers via immigration. As for the USA, it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010-2030,Moreover,the USA has a track record of successfully accepting immigrants. As a result it's likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.

“The gaokao,China's national college entrance exam,is winning more recognition as a way for universities overseas to evaluate Chinese students,”recruiting officers said.
Stanley Nel,vice-president of international relations at the University of San Francisco in the United States,who is responsible for the university's admissions from China,said he had had several inquiries from US universities about how to recruit Chinese students on the basis of their gaokao scores.
The Test of English as a Foreign Language (TOEFL) and the Scholastic Aptitude Test (SAT) have long been two musts for students from other counties,including China,to apply to study in the US.
USF,a private university in California,started a pilot program to accept Chinese students based on their gaokao scores in 2015.The idea came from USF President Paul Fitzgerald's belief that standardized tests like the SAT are not very good predictors of how well students will do at the university."We are aware of the many criticisms that have been made of the gaokao,but it has the advantage of being what educational experts call a 'criterion-referenced' exam: It tests whether students are able to master a given body of knowledge,"he said.
Currently,at least four higher education institutions in the US are recruiting Chinese students based on their gaokao performances.The Illinois Institute of Technology,a private institution in Chicago,started the practice first,in 2009.Outside the US,countries including Spain,Italy,Singapore,France and Australia also recognize gaokao scores.
More than 200 students from China requested an interview with USF last year.74 of them were selected for a follow-up interview,44 received offers and 20 accepted the invitation and joined USF for the 2015 fall semester. Students admitted in this way have done "exceptionally well" in the past academic year,Nel added."The average GPA for all gaokao students is about 3.5 out of 4.For all other students—American and non-gaokao international students—American and non-gaokao international students—the average GPA is 3.2,"he said.
Zhu Zihao gained admission in computer sciences at USF in 2015 through the program and performed well in his first academic year.He said that students who had experienced China's gaokao usually had comprehensive basic knowledge,which helps them excel in studies.
Nel said,"students admitted through China's gaokao are not only smart but extremely conscientious(认真的)and hardworking."
"This year we hope to recruit about 50 students in this way,and even more in years to come,"he said.

It is now mandatory(强制) for drivers or passengers to wear seatbelts while in a car in all states. In addition, it is also mandatory for kids of be in some kind of specialized car seat. Given the strict requirements in other vehicles, why don't buses have seatbelts?
The main answer, at least for school buses, is that seatbelts do not make school buses safer. Overall, traveling on school buses is the safest way to travel—40 times safer than riding in a car—with only a handful of deaths occurring to passengers on school buses every year. The seats on the school bus are placed very close to each other and have high backs that are thickly padded. As a result, in an accident the students would be propelled forward a very short distance into a padded seatback that in a way is like an airbag. In addition, the fact that people sit high off the ground on school buses also makes it safer to travel on them.
While school buses feature high backed seats and elevated seating locations, the same cannot be said of city buses. However, from a practical angle, there's little need to require seatbelts on city buses. Although the design of the modern low—floor city bus is less safe than the design of school buses, the fact that city buses rarely travel at speeds greater than 35 miles per hour means that any collision is likely to be small, Also, given that most trips on city buses are short and that many trips have standing passengers, the presence of seatbelts will make even less of a difference.
Another answer why buses do not have seatbelts is cost. It is estimated that adding seatbelts to buses would add between $8,000 and $15,000 to the cost of each bus. In addition, seatbelts would take up room currently used as seats, meaning that each bus would have fewer seating places. The additional room in the bus taken up by seatbelts would mean that bus fleets would have to increase by as much as 15% just to carry the same number of people. Such an increase would be especially difficult in cities that experience overcrowding on their vehicles.
Regardless of whether their passengers have seatbelts, all buses provide seatbelts for drivers and most bus companies make their drivers wear seatbelts in order not to be influenced by a collision.
