British researchers have found that children’s IQ predicts their probability of becoming vegetarians (素食者) as young adults. Recent studies suggest that vegetarianism may be associated with lower cholesterol (胆固醇), reduced risk of overweight and heart disease. “We know from other studies that brighter children tend to behave in a healthier fashion as adults—they’re less likely to smoke, less likely to be overweight，less likely to have high blood pressure and more likely to take exercise.” lead author Catharine Gale said, “This study provides further evidence that people with a high IQ tend to have a healthier lifestyle.” In the study, Gale’s team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age. “Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30.”Gale said. The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan , and 33.6 percent said they were vegetarian but also ate fish or chicken. There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken，the researchers added. One expert said the findings weren’t the whole answer，however. “We don’t know the beliefs or attitudes of the parents of the children，nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood.” said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas. 小题1:From the article，we know that ________. A．brighter children are likely to become vegetarians when they are ten. B．people with a higher IQ will not be overweight C．brighter children are likely to have a healthier lifestyle D．overweight may cause high blood pressure 小题2:What does the underlined word “vegan” in the sixth paragraph mean? A．Someone who only eats vegetables. B．Someone who chooses not to eat meat or fish. C．Someone who likes eating meat and fish. D．Someone who likes eating vegetables. 小题3:This study left some unanswered questions EXCEPT “________”． A．Did the vegetarian children grow up in a family with a vegetarian parent? B．Did the children eat a primarily vegetarian diet at the age of 10? C．Were meatless meals regularly served in the participants’ families? D．Did the vegetarian children really have a high IQ? 小题4:The main idea of the passage is that ________. A．the low IQ children will be unhealthier when they grow up B．being vegetarians can reduce the risk of overweight and heart disease C．IQ is important to vegetarians D．high IQ children are more likely to become vegetarian when they grow up

Uncovered interest rate parity (UIP) predicts that high yield
currencies should be expected to depreciate.It also predicts
that,ceteris paribus,a real interest rate increase should
appreciate the currency are provided.UIP is one of the
cornerstones of international finance,constituting an important
building block of most important exchange rate determination
theories such as the monetary exchange rate model.
The methods employed in this paper includes a unit root
test for checking the stationarity of the data,a cointegration test
for examining the long-term equilibrium relation between the
NDF and spot rates,an error correction model for testing
causality in time series data.
A widely applied estimation methodology proposed is the
single equation method of Engle and Granger(1987) (hereafter
EG).The OLS estimator of the cointegrating vector is
superconsistent and converge faster than the OLS estimation of
a stationary variables model as showed by Stock
(1987).Cointegration implies long-run equilibrium.The
short-run adjustment towards the long-run equilibrium can be
represented by an error correction mechanism introduced by
Sargan (1984) and popularized by Engle and Granger (1987).
In this paper we attempted to investigate the empirical issue
of market for the RMB to US Dollar using the daily data from
July22,2005 to January10th,2008.The empirical evidence for
the entire sample period indicates that for the long-run,we find
the behavior of the relationship between the corresponding spot
rate and the NDF rates in a cointegration context.Moreover,
Granger causality test results show that RMB’s spot and NDF
rate are influenced deeply each other.Thus we applied VEC
model and analyzed variance decomposition of RMB spot rate
and NDF price.From the results,we can get a result that the
RMB spot market is the leading market and has a significant
impact on.RMB NDF offshore market.
Although the domestic foreign exchange market are
affected by changes taking place in the offshore markets ,the
impact was too small.This means that because of capital
control,it is still possible for governments to pursue
independent economic policies even in the presence of
influence from the offshore market that it has no control over.

Hypothesis 2,which predicts that decision com-prehensiveness will act as a mediator,received par-
tial support.As shown in model 2 of Table 3,the regression of decision comprehensiveness on pre-
dictors revealed that the interaction of debate and education diversity was positively associated with
x09x09x09x09x09x09
decision comprehensiveness (3 = .20,p < .10),as was the debate-by-tenure-diversity interaction
(f3= .36,p < .01).As shown in model 3,decision comprehensiveness predicted change in profitabil-
ity (3 = .37,p < .01) and change in sales (8 = .42,
p < .01).A comparison of the interactions in model
1 with the interactions in model 3 shows support
for a partial mediating effect.Adding decision comprehensiveness as a predictor in the performance
regressions diminished the effects of debate crossed with education diversity and debate with
tenure diversity on change in profitability and change in sales.This result suggests that decision comprehensiveness partially mediates the effects
on firm performance of the interactions of debate and education diversity and of debate and tenure diversity.
Hypothesis 3 predicts that interactions between more job-related forms of diversity and debate will have stronger positive effects on decision compre-
hensiveness and firm performance than will inter- actions between less job-related forms of diversity
and debate.

Smile predicts success of your marriage
A smile in your past photographs is an indication that your marital life will be successful,says scientists.
Psychologists have found that how much people smile in pictures in the past can predict their later success in marriage.
The researchers asked almost 650 adults for pictures taken during their final year school and rate the brightness of their smiles.
The scientists,from DePauw University in Indiana,also asked the volunteers,between 21 and 87,whether they had ever been divorced,and subsequently matched their answers with the data on their smiles.
Those with the weakest smiles were more than three times as likely to have been through a divorce than those who beamed their way through their teenage years,the journal Motivation and Emotion reports.
"Smile intensity predicted whether or not participants divorced at some point in their lives," the researchers said,adding:"The less intensely participants smiled,the more likely they would be divorced later in life."
A second trial,which included pictures taken when people were as young as five confirmed the finding.
Overall,the results indicate that people who frown in photos are five times more likely to get a divorce than people who smile.
The researchers believe that those who are generally happier are therefore more likely to try to work through difficulties in relationships and marriages.
