After setting up a programming model of maximizing the weighted expected utility involving basic securities and contingent claim,and using techniques in optimization analysis,explicit expressions of the fair price interval for a contingent claim were derived. Relations between acceptable price interval and fair price interval were discussed. It is shown that all fair prices fit the demand for acceptability of a market.展开更多

To this end, this paper will explain the meaning of intellectual capital （human capital, structural capital, and relational capital） in the field of knowledge economy and what relational capital is and how we can measure its value. The research is qualitative in nature and was developed through the study of the international literature. The research presents some theoretical evidences that permit defining a method for the evaluation of relational capital. In this direction, the above method will need to have some integration in the future research. Moreover, this approach should consider some empirical evidences to establish the practical value of the method. In fact, the method presented encourages debate and a critical attitude towards the evaluations of relational capital and intellectual capital.展开更多

The author also discusses a proper approach for teaching medical postgraduate students, which is centered on students and based on research. This approach for teaching and leaning has been proved effective and students have improved in their socio-linguistic and pragmatic competences. This approach should have implications to EFL teachers who teach students of other specialties.展开更多

Methods: Sixty three peripheral facial palsy patients were randomized into treatment group (n=33) and control group (n=30). In treatment group, Taiyang (EX HN 5), Jingming (BL 1) and Hegu (LI 4) were punctured with gauge 36 acupuncture needles and stimulated with light twirling reinforcing method (about 200 times/min), the acupuncture needles were retained for 20 min. In addition, moxibustion was also applied to Fengchi (GB 20) and Qianzheng (EX HN 17) following puncturing them with gauge 30 filiform needles. In control group, conventional twirling reducing method (about 60 times/min) was applied to Yangbai (GB 14), Cuanzhu (BL 2), Sizhukong (TE 23), etc., following puncturing them with gauge 28 filiform needles. Additionally, thermal needle was applied to Fengchi (GB 20), Yifeng (TE 17) and Jiache (ST 6), with the needles retained for 40 min. Results: Following 10 days’ treatment, of the 33 and 30 cases in treatment and control groups, 21 (63.0%) and 12 (40.0%) were cured, 7(21.1%) and 5 (16.7%) had remarkable improvement, 4 (12.1%) and 9 (30.0%) were effective, and 1 (3.0%) and 4 (13.3%) failed in the treatment, with the cure plus markedly effective rates being 84.8% and 56.7% respectively. Statistical analysis shows that in acupuncture treatment of early stage of facial palsy, light stimulation is superior to that of heavy stimulation in the therapeutic effect.展开更多

B. plicatilis population and the growth of the two algae were compared at different algal cell densities. The results demonstrated that the B. plicatilis obtained sufficient nutrition from Prorocentrum donghaiense to support net population increase. With exposure to 2.5×104 cells mL-1 of P. donghaiense,the number of B. plicatilis increased faster than it did when exposed to other four algal densities(5,10,15 and 20 ×104 cells mL-1),and the increase rate of B. plicatilis population(r) at this algal density was 0.104 ± 0.015 r d-1. Cell densities of P. donghaiense decreased due to the grazing of B. plicatilis. In contrast,Heterosigma akashiwo had an adverse effect on B. plicatilis population and its growth was largely unaffected by rotifer grazing. In this case,B. plicatilis population decreased and H. akashiwo grew at a rate similar to that of the control.展开更多
