Invited review: A perspective on the future of genomic selection in dairy cattle

Genomic evaluation has been successfully implemented in the United States, Canada, Great Britain, Ireland, New Zealand, Australia, France, the Netherlands, Germany, and the Scandinavian countries. Adoption of this technology in the major dairy producing countries has led to significant changes in the worldwide dairy industry. Gradual elimination of the progeny test system has led to a reduction in the number of sires with daughter records and fewer genetic ties between years. As genotyping costs decrease, the number of cows genotyped will continue to increase, and these records will become the basic data used to compute genomic evaluations, most likely via application of “single-step” methodologies. Although genomic selection has been successful in increasing rates of genetic gain, we still know very little about the genetic architecture of quantitative variation. Apparently, a very large number of genes affect nearly all economic traits, in accordance with the infinitesimal model for quantitative traits. Less emphasis in selection goals will be placed on milk production traits, and more on health, reproduction, and efficiency traits and on environmentally friendly production with reduced waste and gas emission. Genetic variance for economic traits is maintained by the increase in frequency of rare alleles, new mutations, and changes in selection goals and management. Thus, it is unlikely that a selection plateau will be reached in the near future.     

Fast Blended Transformations for Partial Shape Registration

Automatic estimation of skinning transformations is a popular way to deform a single reference shape into a new pose by providing a small number of control parameters. We generalize this approach by efficiently enabling the use of multiple exemplar shapes. Using a small set of representative natural poses, we propose to express an unseen appearance by a low-dimensional linear subspace, specified by a redundant dictionary of weighted vertex positions. Minimizing a nonlinear functional that regulates the example manifold, the suggested approach supports local-rigid deformations of articulated objects, as well as nearly isometric embeddings of smooth shapes. A real-time nonrigid deformation system is demonstrated, and a shape completion and partial registration framework is introduced. These applications can recover a target pose and implicit inverse kinematics from a small number of examples and just a few vertex positions. The resulting reconstruction is more accurate compared to alternative reduced deformable models.     

The resilience of cities to economic shocks: A tale of four recessions (and the challenge of Brexit)

This paper examines the resilience of British cities to major economic shocks. Using a novel data set for 85 cities, it analyses their resistance to and recovery from the last four major recessions, over the period 1971 to 2015. It reveals a distinct shift in the relation between resistance and recovery between these shocks, as well as major differences between northern and southern cities. Some possible factors shaping these patterns are explored, and tentative estimates of the likely impact of the Brexit shock (Britain's withdrawal from the European Union) are also provided. A key implication is that differences in resilience to major shocks can contribute to the long-run growth paths of cities.     

Water–Health Nexus: Modeling the Pathways and Barriers to Water-Related Diseases

Under pressure from climate change and other drivers, the risks of water-related infectious and chronic diseases seem poised to increase. Addressing these risks requires shared work in the fields of public health and water resources management. To help in risk assessment, the paper presents a comprehensive conceptual model of water-related health effects and the potential barriers that can be established by water management actions. The model does not indicate unique solution strategies because multiple water management factors cause multiple types of water-related diseases. It uses the water-health nexus to conceptualize the pathways to diseases and help clarify health-related responsibilities for water management and public health officials. Experiences of the U.S. are presented as an exemplar of the links between water management and disease incidence. However, parts of the water management system are not regulated effectively and many countries lack organized utilities and effective water governance.
