Sci., 22: 222–227 The paper presents an overview of the possibility to use the subterranean clover (Trifolium subterraneum L.) (an annual leguminous self-seeding species, widespread component in the pastures of the temperate areas of Central an...

[1] Large-scale assessments of the potential for food production and its impact on biogeochemical cycling require the best possible information on the distribution of cropland. This information can come from ground-based agricultural census data sets and/ or spaceborne remote sensing products, both with strengths and weaknesses. Official cropland statistics for China contain much information on...

OBJECTIVE Development of a new framework for the National Institute on Aging (NIA) to assess progress and opportunities toward stimulating and supporting rigorous research to address health disparities. DESIGN Portfolio review of NIA's health disparities research portfolio to evaluate NIA's progress in addressing priority health disparities areas. RESULTS The NIA Health Disparities Research...

This paper introduces a new importance sampling technique to increase the efficiency of rare event simulation. By using a multidimensional rotational invariant auxiliary density, this method can be applied to estimate risk measures for credit risk portfolios where the method of importance sampling via mean shifting is not suitable. The loss distribution of the portfolio is obtained by simulatin...

The worldwide concern with corporate governance concerns itself, inter alia, with the risks that an organisation faces; for many, IT is significant among those risks. This paper examines the audit approach, and others, to dealing with risks in IT-based systems. This paper summarises the findings of research in IT-related areas of risk and then draws together a charter for IT governance that mee...

One of the fastest growing areas of scienti c computing is in the nancial industry. Many of the most basic problems in nancial analysis are still unsolved, and are surprisingly resilient to the onslaught of legions of talented researchers from many diverse disciplines. In this article, we hope to give readers a sense of these challenges by describing a relatively simple problem that all investo...

Among the ‘reduced form models’ for measuring the credit risk of a bank’s portfolio is CreditRisk+, which provides a closed-form solution for calculating the portfolio loss distribution based on an actuarial approach. The limitations of this model are well known, but they are often misinterpreted as being deeply embedded within the model. Dismantling the mathematical components of the model all...

The pasture and animal productivity of established high producing pastures in the Waikato has been compared with newly sown pastures based on recently released herbage cultivars. The established pastures were a mixture of Nui perennial ryegrass, Paspalum dilatatum and Htiia white clover. The new cultivars tested were Ellett perennial ryegrass, Wana cocksfoot and Roa tall fescue, each sown with ...
