Pampus cinereus (Bloch, 1795) (Stromateidae), a species believed to be widely distributed throughout the Indo-Western Pacific region, was redescribed and a neotype was designated. The designation of a neotype was necessary because of ambiguous data in Bloch's original description and the loss of the original type specimen. Morphological data indicated that 10 recently-collected specimens from the coasts of southem China agreed well with Bloch's original description and figure ofP. cinereus. A neotype for this species was selected from among the 10 specimens, and a detailed description is presented in this paper. 展开更多

Local development as a local management process tables a number of questions, mainly concerning on conflict resolution between the three power local poles: (1) State and its appointed State peripheral Departments; (2) Local authorities; and (3) Local people and their local movements/lobbies. As the three poles are in a constant negotiations, then each of them should prevail over the other two, thus be introduced in the bargaining problem. Bargaining behavior must therefore be defined. The suggested "'win-win-win papakonstantinidis model" (coming from Nash win-win extended approach) tries to find ways for the three-pole bargaining conceptual equilibrium, under conditions, thus maximizing expected utilities for all the involved parts in local decision-making by applying a combination of Descriptive Behavior (DB), Rational Choice, Instrumental Rationality, and the Applied Behavioral Analysis (ABA) methodologies, then an updating community's behavioral state is expected, thus transforming the technical territory-community perception to a behavioral community perception, by sensitizing its population, towards the "guanxi relations" paradigm. 展开更多

In this paper, the theory and method of the fuzzy mathematics areused to probe the connection between the activity of the active region and characterizat ion of the sunspot groups, to build the subordinating function according to the rela tionship between them and to evaluate comprehensively the activity of the active region on t he solar disk. The precise prediction of activity of the active regions has been obta ined by data reduction and analysis. The predicting accuracy is higher th an 95% . Forecast results indicate that the method of the fuzzy comprehensive evaluatio n is a good one for the solar activity prediction. 展开更多
