The objectives of this presentation are to review results of our previous and on-going research with respect to the risk factors and consequences of poor reproductive performance in dairy cows, and to develop an economic framework to optimize decisions related to dairy cow reproductive performance. To make profitable breeding and replacement decisions, the farmer must account for factors includ...

BACKGROUND In patients with stage II colorectal cancer (CRC) the number of surgically retrieved lymph nodes (LNs) is associated with prognosis, resulting in a minimum of 10-12 retrieved LNs being recommended for this stage. Current guidelines do not provide a recommendation regarding LN yield in T1 CRC. Studies evaluating LN yield in T1 CRC suggest that such high LN yields are not feasible in t...

Coherent and convex risk measures, Choquet expectation and Peng’s g-expectation are all generalizations of mathematical expectation. All have been widely used to assess financial riskiness under uncertainty. In this paper, we investigate differences amongst these risk measures and expectations. For this purpose, we constrain our attention of coherent and convex risk measures, and Choquet expect...

This paper discusses possible approaches to the construction of gilt yield indices pub lished by the Financial Times The existing method described by Dobbie and Wilkie splits bonds into high medium and low coupon bands and ts separate yield curves to each In recent years this method has been identi ed as susceptible to catastrophic jumps when the least squares t jumps from one set of parameters...

We study the contemporaneous and intertemporal partial relation between T-bond pricing and changes in equity risk, as measured by the implied volatility from equity-index options. Our 1992 to 2007 sample is attractive because of the modest inflation risk and sizable time-series variability in equity risk. Over 1997 to 2007 and for inclusive one-half and one-quarter subperiods, we find that the ...

This paper documents that the earnings yield and book-to-price combine to predict equity returns in a way that is consistent with the rational pricing of risk. It is well known that earnings yields predict returns in the cross-section, consistent with standard formulas that show that the earnings yield equals the required return when there is no expected earnings growth beyond that from retenti...

T paper studies the role of the yield-dependent trading cost structure influencing the optimal choice of the selling price and production quantity for a firm that operates under supply uncertainty in the agricultural industry. The firm initially leases farm space, but its realized amount of fruit supply fluctuates because of weather conditions, diseases, etc. At the end of the growing season, t...

We explore the determinants of yield differentials between long-term sovereign bonds in the Euro area. There is a common trend in yield differentials, which is correlated with a measure of the international risk factor. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We present a model that predicts that yield differentials should increase in both liqui...

BACKGROUND In 2012, the United Kingdom (UK) Government announced that the new entrant screening for active tuberculosis (TB) in Heathrow and Gatwick airports would end. Our study objective was to estimate screening yield and diagnostic accuracy, and identify those at risk of active TB after entry. METHODS We designed a retrospective cohort study and linked new entrants screened from June 2009...
