Abstract:
The relationship of the
IT and competitive advantage is a hot research topic for a long time. Based on existing
research, this paper proposes an integrated procedure model of how IT impacts firm’s
competitive advantage. The model provides an integrated framework for the study
of the relationship of the IT and competitive advantage, and can provide
effective guidance for firms to use IT to obtain sustainable competitive
advantage.

Abstract:
This paper studied the
joint effects of network position and technological distance on firm’s cooperation innovation based on the data of firm’s patent cooperation
from 2003-2013 in the electronic information, electric power and equipment
manufacturing industry. Results show that both network centrality and structure
holes have a significant positive impact on the firm’s cooperation innovation
output; technological distance and cooperative innovation performance have an
inverted u-shaped relationship; the interaction of network centrality and
technological distance negatively regulates the cooperative innovation
performance; the interaction of technological distance and structure holes can
promote cooperative innovation performance.

The increase in international trade and the information technology boom led us to begin to face the previously unthinkable of academic shortage towards vocational education. The main objective of this paper is to present the problem and find ways to solve it. The main finding included lack of investment from society and high degree involvement of government, the curricula is without of academic flexibility, students are sorted into different school types largely on the basis of their entering exam score, shortage of high-quality teachers and instructors. Thus this paper puts four ways to tackle the problem: decrease the involvement of government; setting hybrid curricula and providing technical research project; providing attractive option that the possibility to study further in university for vocational school graduates; emphasizing general and academic knowledge over industry and vocational skills by aligning academic institutions and firms.

Abstract:
Ball-milling graphite was conducted in miscible solutions with the purpose to exfoliate graphene. Colloid-like stable supernatants were unexpectedly obtained. Followed were the characterizations with Scanning electronic microscopy, Thermogravimetric analysis, X-ray diffraction and Elemental dispersive X-ray mapping to recognize them. As a result, strongly against the initial judgments, the components of colloid were mainly impurities of mixture of zirconia, silicate and yttrium oxide, other than nano-graphite.

To investigatetheinfluences of the application of human care
theory on the life quality and happiness of cancer patients after they receiveda
community nursing care which was implemented by the human care theory. The
quality life and the happiness index of 93 patients with cancer living in the
six communities in Jillin were assessed, the assessment of the life quality was
based on a life quality scale (SF-36) and that of the happiness index was based
on Memorial University of Newfoundland Scale of Happiness (MUNSH). The
community nurses cared for these patients by applying the theory of human care
and the life quality and the happiness index of the patients were observed
after the care. The results showed that there were significant differences in
the score of 5 dimensions in the eight dimensions of the life quality between
before the care and after the care (<0.05), and there were significant
differences in the average sores of the positive emotion, positive experience,
negative emotion, negative experience and level of happiness included in the
happiness index between before the care and after the care (<0.05),
suggesting that the theory of human care can be used for the care of patients
with cancer and the application of the theory can effectively improve the life
quality and the happiness index of the patients, strengthen their
problem-solving abilities and let them have a positive attitude towards their
lives.

Conventional arc models are usually used to research the
interaction between switching arc and circuit. It is important to simulate the
fault arc for arc flash calculations, choice of electrical equipments and power
system protection. This paper investigates several conventional arc models for
calculating the fault arcing current. Simulation results show that conventional
arc models can be used to simulate the fault arc if the parameters of arc models
are given properly. This paper provides the parameters of 5 popular arc models
and describes the simulation results of the fault arc.

Since , we know that the upper bound in the inequality (1.5) is better than the one in (1.3). At the same time, we find that the lower estimate in (1.5) is larger than the one in (1.3) on the interval meanwhile the lower estimate in (1.3) is larger than the one in (1.5) on . 2.

Particularly, , , and . We also use Lemma 2.1 in order to give the lower bound of for : We denote that where Let , and We compute that So is increasing on . Since and , we have that is decreasing firstly and then increasing. Let be only one point

Abstract:
With the wide employment of modern educational technology, college English teaching is going on a process of replacing traditional educational media with modern ones, which are closely connected with multimedia computers and internet technology to raise its efficiency and quality. However, some problems and challenges still exist in the college English teaching. In order to solve the problems, this article designs a test and collects data to check the effectiveness of the task-based approach within the Internet-assisted multimedia in college English teaching. The results show that Linguistic form was analyzed and practiced with task-based approach which may help the learners notice the linguistic problems and try out new language forms and structures, and that Internet-assisted multimedia has been effective in intriguing learners' interests and greatly enhanced their self-esteem.
