The Arabidopsis DA1 genes appear to have multiple functions in regulating organ size and abiotic stress response, but the biological roles of its closely related genes remain unknown. Evolutionary analyses might provide some clues to aid in an understanding of their functional diversification. In this work, we characterized the molecular evolution and expressional diversification of DA1-like ge...

In the process of traditional economy transforming into modern economy in china, farmer’s diversification phenomena has arisen and developed and will continue a long time in the future. Accordingly, the general economic type of farmer diversification will effect on the rural source allocation. The land use behavior characteristics of diversification farmer are the aims of the study. Theoretic a...

in the recent years, the relationship between diversification and performance became an important empirical subject in financial management. diversification strategies can affect the competitive balance of an industry. in this survey we are to illustrate the relationship between the two variables of diversification and financial ratios as performance criteria based on accounting through statist...

This review explores features of the origin and evolution of colicins in Escherichia coli. First, the evolutionary relationships of 16 colicin and colicin-related proteins are inferred from amino acid and DNA sequence comparisons. These comparisons are employed to detail the evolutionary mechanisms involved in the origin and diversification of colicin clusters. Such mechanisms include movement ...

Molecular phylogenies have been used to study the diversification of many clades. However, current methods for inferring diversification dynamics from molecular phylogenies ignore the possibility that clades may be decreasing in diversity, despite the fact that the fossil record shows this to be the case for many groups. Here we investigate the molecular phylogenetic signature of decreasing div...

This study examines the impact of hierarchical complexity on corporate opaqueness and how this relationship varies under moderating effect diversification. We hypothesise that increases in firms’ are related to greater between firm outside investors capital market. Using a sample U.S. firms spanning 5 years from 2012 2016, we find statistically economically significant, positive opaqueness. The...

Using advanced techniques of econometrics and a metaheuristic optimization approach, this study attempts to evaluate the potential advantages of international portfolio diversification for East Asian international investors when investing in the Middle Eastern emerging markets. Overall, the results of both econometric and the metaheuristic optimization methods are supporting each other. Finding...

Traditionally, patterns and processes of diversification could only be inferred from the fossil record. However, there are an increasing number of tools that enable diversification dynamics to be inferred from molecular phylogenies. The application of these tools to new data sets has renewed interest in the question of the prevalence of diversity-dependent diversification. However, there is gro...
