This paper investigates the impact of internet on economic growth and this impact during the recession. The data are drawn from World Bank in a panel of 201 countries from 1988 to 2010. Results from an OLS model reveal that a 10 percentage point increase in internet penetration rate raises real GDP per capita by 0.57 to 0.63 percentage points. During the recession relative to expansion, the coefficient of internet reduces but it still remains statistically positive. This suggests that internet provides a way to solve the problem of economic recession. Our results are robust to the inclusion of time and country fixed effects.
There are many types of almost frictionless and very rapid flows of complex molecules in nature. One example is the almost frictionless nature of the protein channel aquaporin-1. Nearly frictionless transport of complex biomolecular fluids along a membrane composed of wavy-rough nanoannuli was investigated by using the verified Eyring’s transition-state approach (cf. Journal of Physical Chemistry B, Vol. 112, 2008, pp. 3019-3023.), together with a boundary perturbation approach, which has been successfully adopted to study the selective transport of polymeric matter in confined nanodomains. The critical parameters related to the rapid or nearly frictionless transport of biomolecules were identified to be directly relevant to the possible phase-transition temperature after selecting specific activation energies and activation volumes for fixed confined (cylindrical) geometry as well as small wavy corrugations along the interface. Our results can also make the membrane composed of aligned wavy-rough nanotubes a promising mimic of protein channels for transdermal drug delivery and selective chemical sensing.
The trust as a social relationship captures
similarity of tastes or interests in perspective. However, the existent trust information
is usually very sparse, which may suppress the accuracy of our personal product
recommendation algorithm via a listening and trust preference network. Based on
this thinking, we experiment the typical trust inference methods to find out
the most excellent friend-recommending index which is used to expand the
current trust network. Experimental results demonstrate the expanded
friendships via superposed random walk can indeed improve the accuracy of our
personal product recommendation.
To enrich literature, this paper investigates influence
of living with parents on marrieds’ happiness. It is an important issue in
Chinese filial piety culture but rarely discussed. Data are drawn from Taiwan
Social Change Survey in year 1995, 1997, 2000, 2001, 2002 and 2005. Empirical
findings from ordered probit models show various associations between living
with own/spouse’s parents and happiness of married women/men. Living with mother-in-law
degrades married women’s happiness but it promotes married men’s happiness. Living
with own mother lowers down married daughter’s happiness but
married men’s happiness increases when living with own parents. These results
echo to theoretical backgrounds about altruism, demonstration effect, and
good/bad relation between married children and parents.
In this paper, we
analyze the default risk of Chinese real estate companies with KMV model and
time-varying copula. We collected the data of the listed real estate companies
in Shanghai and Shenzhen Exchanges from 2007 to 2012 to calculate the default
distance and correlations. Experiments results show that the default risk increases
during the financial crisis. Moreover, results also indicate the default risk aggregation.
The difference of default risk between the large size and small size companies
is also examined in this research. Due to the high asset liability ratio, the large
size companies face higher default risk than the small size companies. Finally,
time-varying copula shows that the correlation between different-sized
companies fluctuates severely during the financial crisis and then goes
smoothly after the crisis.
The purpose of this
is to investigate how adult female learners constitute their perceptions of
self and learning behavior in an internet learning environment—weblog. Based on
previous qualitative research method and literature review, this study intended
to develop and validate a feminist adult learning strategy scale (FALSS) to
understand the women’s learning strategy by applying weblogs. 417 valid data
from the participants in two studies (exploratory and confirmatory factor
analysis) were analyzed for the purpose. The results of these studies supported
a 15-item, 4-factor FALSS: Empowerment Attempt, Sharing Expe- riences, Participatory
Learning, and Critical Thinking and Open-Mindedness.
The paper mainly studies the influences of
trust transfer on the establishment of consumers’ initial trust. Based on the
theory of signal transmission and self-efficiency, the study builds a trust
transfer model aiming at the same subject between different environments. The
results shows that when the consumers’ perceived change of environment is
little, prior successful experiences will improve the consumers’ perceptions of
self-ability, which probably lowers the effect of bank’s role on the
establishment of initial trust. Therefore, banks should cultivate consumers’
perceptions of their relative advantages in the original environment and thus
improve the consumers’ dependency in the new environment to avoid the loss of
consumers and build a long-term relationship.
