This article briefly explores the nature of price risk faced by Australian broad acre farmers and outlines some farm management ramifications of price risk. The article describes the variation in price risk across time and across commodities. The underlying distributional form of prices faced by farmers is shown to have important ramifications for farm management. The likelihood of increases in...

While both public and private financial agencies supply asset markets with large amounts of information, they do not generally disclose all assetrelated information to the general public. This observation leads us to ask what principles might govern the optimal disclosure policy for an asset manager or financial regulator. To investigate this question, we study the properties of a dynamic econo...

This paper proposes a method for constructing an experimental power beam pattern (PB) of RATAN-600 based on the sample of NVSS sources observed in the process of a deep sky survey near local zenith. The data obtained from observations of radio sources at λ7.6 cm in nine bands of the survey (the 2002 and 2003 sets) are used to construct vertical PB of the telescope at rather large offsets from t...

At the beginning of the twentieth century, little of the world outside of Europe, India, and parts of North America had been covered by topographic mapping. By the end of the century there were few areas that were not covered by topographic mapping, if only at small scales. Most of the technological changes that made this extension of map coverage possible were pioneered during the period 1900-...

This commentary aims to focus, among the “multiple roles of ata generated in ethnopharmacological field studies” (Heinrich t al., 2009, p. 1), on the systematic collection of clinical data. ven if this issue may somewhat resemble what has long been aid (Martin, 1996), recent experiences with clinical assessment f the effectiveness of medicinal plants may shed some new light. his commentary is a...

Methods Data are based upon the Adult Complementary and Alternative Medicine supplement, the Sample Adult core, and the Family core components of the 2007 NHIS. The survey contained reasons for using CIH including treatment of a specific health problem, general wellness or general disease prevention, and other reasons. We created four mutually exclusive categories for analysis: 1) “yes” to trea...

PURPOSE To demonstrate the effect of ethics education on a resident's ability to answer questions that relate to moral dilemmas and on the clinical evaluations of residents by faculty.

One residen...

In many industrial countries, ownership rates of risky assets have risen substantially over the past decade. This trend has potentially wide–ranging implications for the intertemporal and cross–sectional allocation of risk, and for the macro economy, establishing the need for understanding ownership dynamics at the micro level. This paper offers one of the first such analyses using representati...

These data highlights are based on analysis of the 2001 National Health Interview Survey (NHIS) public use data (http://www.cdc. gov/nchs/nhis.htm). NHIS is a multi-purpose survey conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. NHIS has been conducted continuously since 1957.
