Farmers play a key role in conserving native livestock breeds, but without economic support, farms with breeds may not be viable. We hypothesized that terminal crossbreeding can improve herd economy and decrease the support needed from society. Three scenarios were simulated using SimHerd Crossbred: of purebred Swedish Polled Cattle, Red, 75% Cattle 25% F1 crossbreds. The results showed annual ...

Plate reconstructions of the New Zealand region indicate substantial Cenozoic tectonic rotation of the Hikurangi margin. This study was undertaken to determine the rotational history of the northern Marlborough paleomagnetic domain in the southern part of the Hikurangi margin. Most Cenozoic rocks in the Marlborough region are unstably magnetised, and useful results were obtained only from late ...

This paper presents a validation framework for collateral requirements or margins on a derivatives exchange. It can be used by investors, risk managers, and regulators to check the accuracy of a margining system. The statistical tests presented in this study are based either on the number, frequency, magnitude, or timing of margin exceedances, which are de…ned as situations in which the trading...

In this communication, hexapod tripod gaits for straightline motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapod for walking with a prescribed stability margin either over perfect ter...

The presence of options in a portfolio fundamentally alters the portfolio’s risk and return profiles when compared to an all equity portfolio. In this paper, we advocate modeling a risk-based criterion for optioned portfolio selection and rebalancing problems. The criterion is inspired by Chicago Mercantile Exchange’s risk-based margining system which sets the collateralization requirements on ...

abstract marketing element’s contrastive behaviors toward price risk had considerable effect on marketing margin in a way that transferring increase in price to final consumer, reduces purchasing power and so consumption amounts of consumers. present study evaluated effective parameters on marketing margin in 2 level of ranch-processing and processing- retail of beef and lamb with consideration...
