Both community ecology and conservation biology seek further understanding of factors governing the advance of an invasive species. We model biological invasion as an individual-based, stochastic process on a two-dimensional landscape. An ecologically superior invader and a resident species compete for space preemptively. Our general model includes the basic contact process and a variant of the...

This study examines the relationship between the life insurance and economic growth in India. The total life insurance premium (TLIP), and total life insurance investment (TLII), are used as proxy for life insurance and Gross Domestic Product (GDP) is used for the economic growth. The data has been compiled from the Handbook on Indian Insurance Statistics, IRDA annual reports and economic surve...

The finance-growth nexus is discussed with respect to possible conclusions from economic history, contributions from economic theory as well as recent empirical crosscountry studies. Then, a new proxy for financial development is introduced, which refers to the input of real resources into the financial system. Based on this proxy, an empirical framework is elaborated to clarify the importance ...

This research analyzes the dynamic properties of the difference equation that arises when markets exhibit serial correlation and mean reversion. We identify the correlation and reversion parameters for which prices will overshoot equilibrium (“cycles”) and/or diverge permanently from equilibrium. We then estimate the serial correlation and mean reversion coefficients from a large panel data set...

Japan's politics and society appear to be sinking deeper into turmoil and lethargy. Numerous signs abound: politicians intent on deposing each other rather than engaging in policy discourse; a sadistic bent by some of the media; diplomacy carried out on an ad hoc basis; a budget-cutting panel (shiwake) by populist politicians that shrinks long term social investment and innovative initiatives; ...

We have studied the dependence of Au-assisted InAs nanowire (NW) growth on InAs(111)B substrates as a function of substrate temperature and input V/III precursor ratio using organometallic vapor-phase epitaxy. Temperature-dependent growth was observed within certain temperature windows that are highly dependent on input V/III ratios. This dependence was found to be a direct consequence of the d...

Solar radiation induces both acute and chronic responses in the skin. Sun burn, sun tan, generation of reactive oxygen species and immunosuppression are acute responses. Wrinkles, lentigines, post-inflammatory pigmentation are chronic damages. According to one study done in Japan, it was found out that the annual ultraviolet dose received by people living in Kagoshima was 1.6 times higher than ...
