Study on single nucleotide polymorphisms of H -FABP gene in sheep por Qiao, H.Y., Zhao, Q.J., Yao, N., Lu, Y.-Z., Meng, X.-R., Guan, Wei-Jun, Ma, Y.H., Han Jianlin

“…A chi-square analysis suggested that the allele frequencies and genotype frequencies of H-FABP were in Hardy-Weinberg equilibrium except the Tan and Suffolk populations. Statistical analysis revealed a low polymorphism information content (PIC) in the Suffolk and Tan × SH F1 populations (PIC< 0.25) but an intermediate PIC in the remaining three populations (0.25< PIC <0.50). …”

Land health surveillance and response: a framework for evidence-informed land management por Shepherd, Keith D., Shepherd, G., Walsh, Markus G.

“…Key elements of the science framework are: (i) repeated measurement of land health and associated risk factors using probability based sampling of well defined populations of sample units; (ii) standardized protocols for data collection to enable statistical analysis of patterns, trends, and associations; (iii) case definitions based on specific diagnostic criteria; (iv) rapid low cost screening tests to permit detection of cases and non-cases in large numbers of samples; (v) cost-effectiveness evaluation of interventions based on projected reduction in risks and problem incidence; (vi) design of statistically analysable studies to evaluate interventions in the real-world; (vii) meta-analysis of these data to guide design of public policy and intervention programmes; and (viii) integrating surveillance and the communication and use of results into operational systems as part of regular policy and practice. …”
