Morphology and foliar chemistry of containerized Abies fraseri (Pursh) Poir. seedlings as affected by water availability and nutrition

• We present the results of a two-year (2007–2008) greenhouse study investigating the effect of water availability and nitrogen fertilization on the growth, biomass partitioning, and foliar nutrient content of Abies fraseri (Pursh) Poir. • Fertilizer and moisture content (irrigation) were varied in a factorial experiment combining four levels of irrigation and three levels of fertilization to evaluate growth and foliar nutrient content. In addition, a numerical optimization was used to estimate appropriate levels of each factor necessary to achieve simulated goals for response variables. • Irrigation increased the height growth by 12 to 35% depending on the fertilization treatment (p = 0.0001). Fertilization increased height growth by 10 to 26% (p = 0.02). A similar response was observed for stem diameter growth (SDG). Total biomass accumulation increased as result of positive response of stem and root biomass development, and foliar nitrogen content was positively affected by nitrogen fertilization and negatively affected by irrigation. The numerical optimization for simulated target growth and nitrogen content responses produced levels of input combinations with high desirability factors to achieve the target responses. • These results suggest that nutrient addition is a strong determining factor for early development of this species. The improved growth efficiency in this study is likely attributed to a combination of factors including, improved photosynthetic capacity, decreased stomatal limitations, or increased resource allocation to stems

Tools for Financial Innovation: Neoclassical versus Behavioral Finance

The behavioral finance revolution in academic finance in the last several decades is best described as a return to a more eclectic approach to financial modeling. The earlier neoclassical finance revolution that had swept the finance profession in the 1960s and 1970s represented the overly-enthusiastic pursuit of only one model. Freed from the tyranny of just one model, financial research is now making faster progress, and that progress can be expected to show material benefits. An example of the application of both behavioral finance and neoclassical finance is discussed: the reform of Social Security and the introduction of personal accounts.

Financial services and the urban system: an exploration

Financial services have come to represent an increasingly important sector in the economies of developed nations. Although a substantial literature has accumulated on this topic, relatively little attention has been given to the locational aspects of � nancial services. An attempt is made here to examine the spatial structure of this sector in terms of the urban system, drawing on the principles of central-place theory, the limitations and applicability of which are considered. This is followed by a discussion of the salient features of financial services within the overall urban system. After describing the differentiation of financial services in frequency terms, the hierarchical structure of the UK urban system is outlined. These two aspects are then related, in order to demonstrate the ordered nature of the spatial structure of financial services. There follows a brief discussion of the findings and their implications for future wor
