In this paper, we mainly seek conditions on which the geometric properties of subclasses of biholomorphic mappings remain unchanged under the perturbed Roper-Suffridge extension operators. Firstly we generalize the Roper-Suffridge operator on Bergman-Hartogs domains. Secondly, applying the analytical characteristics and growth results of subclasses of biholomorphic mappings, we conclude that the generalized Roper-Suffridge operators preserve the geometric properties of strong and almost spiral-like mappings of typeβand orderα,SΩ⁎(β,A,B)as well as almost spiral-like mappings of typeβand orderαunder different conditions on Bergman-Hartogs domains. Sequentially we obtain the conclusions on the unit ballBnand for some special cases. The conclusions include and promote some known results and provide new approaches to construct biholomorphic mappings which have special geometric characteristics in several complex variables.

Methodological Comparison

AbstractThis contribution aims at an original comparison of development analysis with Elinor Ostrom and Esther Duflo from a methodological standpoint, scrutinising their relationship to theory and their operative research strategies. Both perspectives are investigated as case studies for a broader discussion about significant trends in economics and social sciences. Duflo and the J-PAL's approach illustrates – in its own way – new trends and some blind alleys in contemporary forms of mainstream economics, whereas Ostrom and the Bloomington school point towards the marked theoretical and methodological reflexivity of institutionalism, its sensitivity to historical diversity and openness towards social sciences. Distinct social philosophies and episteme are at stake displaying a great divide between two brands of realism and pragmatism, two relationships to development, expertise and knowledge. The paper also contrasts Duflo's methodological monism and mechanistic piecemeal analysis with Ostrom's methodological pluralism and adaptive complex systems analysis.

Abstract. The challenges that face scientists in the bourgeoning field of hydropedology include many of those that face investigations in complex systems. We suggest hierarchy theory as being particularly helpful in teasing through complexity in hydropedological investigations. We present a brief overview of hierarchy theory highlighting the importance of defining levels of analysis, the role of theory in prediction, and the importance of narrative in science. These concepts are highlighted by references from the hydropological literature. We point out several issues common to scientists faced with complex systems analysis, and suggest several strategies to help hydropedologists deal with them. In order to help bridge the gap between theory and application, we present several specific examples of how hierarchical treatments have helped scientists deal with the modeling and analysis of complex systems related to hydropedology. We conclude that hierarchy theory offers many powerful tools with which to tackle the complexity inherent in soil water interactions, and that its use would benefit a more systematic and robust integration of the hydrologic and soil sciences.
