This paper surveys evaluation and pricing of tuition fee from two perspectives: society and school. We use the optimization theory in fuzzy mathematics and operations research to establish the evaluation model based on overall society and school satisfaction degree; Taking maximum overall Satisfaction degree as our goal and all factors of comprehensive tuition fee evaluation as the restriction, we establish the optimization model of tuition fee pricing to get the tuition standard in higher education. Then we classify disciplines according to the specific reality and calculate the grades and reference prices in disciplines of three schools in Guangdong Province, China. We further obtain the reference tuition fee in other provinces using the regional conversion coefficient. At last we give our directions for tuition fee pricing of higher education.[...] Read more.
Security schemes of pairwise key establishment plays a fundamental role in research on security issue in wireless sensor networks. However, establishing pairwise keys in wireless sensor networks is not a trivial task, particularly due to the resource constraints on sensors. In this paper, we prose an efficient key distribution scheme, in which each sensor node randomly selects two key pools from several different key pools and chooses keys from these key pools. The analysis shows that this proposed scheme can substantially improve the security of existing key predistribution scheme.[...] Read more.
Human capital, scocial capital and employment type are the main factors which affect labour income, and the differentiation of labour income is based on these factors. This paper, from the basic theory of human capital ,social capital and employment, through the manipulating of these factors, based on a experiential method, tests the significant factors affecting labour income. And we finds that human capital and employment type has positive effect on migrants’ labour income, while social capital has no prominent effect on migrant farmers’ labour income. Based on the deep analysis, this paper brings forward some advice to advance migrant farmers’ labour income based on the perspective of education.[...] Read more.
This paper analyzes the Web services architecture, technology infrastructure and the mode of operation for Web Services in the online shopping. This design the based Web Services in B2B electronic transaction management system by using the C # and SQL Server database. The characteristic is to analysis deep the Web Services technology and use it to the online shopping system.[...] Read more.
The current state and problems of the graduate students’ education in China are set forth in the first. Then, the causes of problems are deeply analyzed. Some ideas and methods in engineering specialty graduate student’s education are offered with co-founding by colleges and enterprises, uniting of production, learning and researching. Some problems that should be noted are pointed out, finally.[...] Read more.
With rapid transition in China, young migrant labors begin to replace old ones. However, there are still many obstacles to the citizenization process of young migrant labors, and the main difficulty is social exclusion. From the perspective of social exclusion，this paper uses Logistic Regression, OLS and Ordered Probit to explore the education level‟s impact on young migrant labors‟ social exclusion. Eventually the research discovers that years of education, family burden, psychological gap and friend relationship have a significant effect, and the regression results are steady. Based on it, this paper proposes several ideas of strengthening rural education and reducing exclusion.[...] Read more.
The existing problems such as teaching materials, teaching methods and assessment links of the forestry panorama course teaching are pointed out and some solutions to the problems in thinking are put forward. In addition, the importance and curriculum of the forestry panorama as an entry and enlightenment course is emphasized. The main goal of this paper is to make positive exploration for further deepening reform of course teaching and cultivate high-level forestry talents, and it is hoped to improve course teaching.[...] Read more.
Based on the theory of constructivism and analysis of characteristics and mental types of students in vocation college, the new classroom teaching model is constructed. Illustrated with the course of municipal engineering planning the design and practice of classroom teaching were discussed and the theory of project planning was applied to the practice of teaching based on the new classroom teaching model reaching to better effect of teaching and learning.[...] Read more.
When the student population size of a school or college reaches a certain amount or critical value, student groups will occur a qualitative change, this can be seen most clearly occurrence of various incidents is a conspicuous rise within student groups, the type of incidents occurred more is diverse and facing the situation is even more complex. The article attempts to puts forward the critical value of a school entity population size and its impact factors, and states the management strategy after the population size exceeded the critical value from the viewpoints of proportionate relationships of teachers and students.[...] Read more.
In order to solve the broadcast storm problem caused by blind flooding, a cross-layer dynamic probabilistic broadcasting strategy for mobile ad hoc networks (CLDPB) is proposed. CLDPB adopts the cross-layer design, which let routing layer share the received signal power information at MAC layer while still maintaining separation between the two layers. The additional transmission range that can benefit from rebroadcast is calculated according to the received signal power, which is applied to dynamically adjust the rebroadcast probability. CLDPB reduces the redundant retransmission and the chance of the contention and collision in the networks. Simulation results reveal that the CLDPB achieves better performance in terms of the saved-rebroadcast, the average packet drop fraction, the average number of collisions and average end-to-end delay, which is respectively compared with the blind flooding and fixed probabilistic flooding applied at the routing layer while IEEE 802.11 at the MAC layer.[...] Read more.
In order to improve teaching level, quality and effect, more and more attention has been paid to the tendency of research teaching being one part of teaching reform in higher education. The research teaching model is proposed that opposite to in unidirectional knowledge instruction teaching model primarily, it refers to the teaching system melting study and research as a body. The research teaching model is the research undergraduate college teaching basic teaching model. Starting with the significance and the conduction of research teaching, this paper puts forward and analyzes several patterns of research teaching, discusses the important role of teachers in these patterns and proposes some strategies as well as suggestions.[...] Read more.
Chemistry is very interesting, but it is often regarded as a difficult subject. Computer software can make chemistry teaching easier, and keeps the students active. This paper seeks to introduce some implications of computer softwares in chemistry classroom teaching. These softwares include Powerpoint, Chemoffice, computer simulation softwares, LabVIEW software, some computational chemistry softwares, and other chemistry softwares, such as ACD/ChemSketch, ChemDB software, Chemical Reagent Calculator, Atom Builder and Atoms, Symbols and Equations. We gave the simple directions of these softwares and presented some applicable examples.[...] Read more.
