In this exposé we provide the first review of host use by brood parasitic cuckoos in a multiple-cuckoo system in China, based on our own long-term field data and a compilation of observations obtained from the literature. In total, we found that 11 species of cuckoos utilized altogether 55 host species. These hosts belong to 15 families, in which Sylviidae, Turdidae and Timaliidae account for 22.6%, 20.8% and 17.0% of parasitism records, respectively. The Common Cuckoo (Cuculus canorus) had the widest range of host species, accounting for 45.5% of the total number of parasitized species (25 in 10 families) of all parasitism records and is the most frequent brood parasite in the country. Cuckoo species differed in their egg coloration and the extent of egg polymorphism with most of them, e.g. the Common Cuckoo, the Lesser Cuckoo (C. poliocephalus) and the Plaintive Cuckoo (Cacomantis merulinus) laying well mimetic eggs with respect to their hosts based on human being’s visual observations, while others such as the Large Hawk-cuckoo (C. sparverioides), the Himalayan Cuckoo (C. saturatus) and the Asian Emerald Cuckoo (Chrysococcyx maculatus) usually laid non-mimetic eggs. The use of cuckoo hosts and egg color variation in China are compared with those in other parts of their ranges in Asia. 展开更多

Driving simulators involve the capability of simulating critical and dangerous driving situations up to the limits of active safety. They are employed for investigating the interactions of the driver-vehicle system under reproducible and non-dangerous conditions. Because of their flexibility they are well established in scientific research. They are mainly used in current automotive fields of research like driver assistance and autonomous driving systems. The development of assistance systems makes the human being as the directly concerned component irreplaceable in the development process. Here the use of driving simulators has become an essential element, because they offer the possibility to integrate the human being as a real part into the simulation environment. It must be considered that the circuit of information has to be the same as under real driving conditions. Otherwise the results are not transferable. This paper deals with the possibilities of presenting all information to the driver, which are necessary to give him a realistic impression of driving. A main subject is the sensation of yaw-movements, which could be of interest when novel kinds of moving base systems are designed. 展开更多

This paper conducts analysis on the educational evaluation standard value based on the normative perspective. Systematic evaluation refers to the determination of the nature and state of a system by means of an effective standard, based on the clear system objective, structure, and system properties, and then compares it with a set of evaluation criteria and makes a judgment. The evaluation result is also the interaction of the product. The education evaluation which is constructed with the dialogue thinking is democratic, friendly, open, win-win, and the evaluation of creation. Educational evaluation is not a party to the other party as superior, judgment, conclusion, one-way row order, but both sides of the equality. Under this basis, this paper proposes the educational evaluation standard value based on the normative perspective. In the future, we will apply proposed method into the general applications to verify the effectiveness and systematic effectiveness. 展开更多

The systemic view on industry and on production and consumption pattern is an essential feature of the industrial ecology (IE) concept. One consequence of this view is to investigate industrial flows and consumer activities, and their effects on the environment in order to evaluate and eventually optimize these flows with the help of a systems methodology. Industrial ecology has been developed by engineers and natural scientists and its ethical core canon often manifests in anthropocentric assertions such as harmonizing the contradiction between nature and culture with scientific expertise, appropriate technology and socio-economic management. This paper argues however for a biocentric inspired, normative reading of some characteristics of industrial ecology's systems methodology. The presumption for the value of this endeavor is that industrial ecology's systems methodology has a potential for developing directions for the design of a possible sustainable world. 展开更多
