A well-defined breeding objective provides commercial producers a mechanism for extracting value from the investment in genomics by seedstock producers. Advantages of genomic prediction include increased accuracy of expected progeny differences (EPDs) for traits that have been components of routine genetic evaluations. Perhaps more importantly, genomic prediction makes it possible to include tr...

This study explored protective factors against prenatal depression in pregnant women. One-hundred thirty-four pregnant women were recruited from an obstetric clinic and public health center in Korea. Dyadic adjustment, sense of mastery, and prenatal depression were assessed using structured questionnaires. Prenatal depression was assessed with the Edinburgh Postnatal Depression Scale (EDPS). Bi...

Artificial selection of cattle has been practiced for centuries using a variety of methods and tools. Early selection was based on visual observations that eventually lead to the development of breeds. In efforts to improve production, selection was practiced on measured phenotypic traits with limited success depending on the heritability of the trait. The next big breakthrough in selection too...

Portfolio optimization problems on a finite time horizon under proportional transaction costs are considered. The objective is to maximize the expected utility of the terminal wealth. The ensuing non-smooth timedependent Hamilton-Jacobi-Bellman (HJB) equation is solved by regularization and the application of a semi-smooth Newton method. Discretization in space is carried out by finite differen...

  Background: Educational clinical environment has an important role in nursing students' learning. Any difference between actual and expected clinical environment will decrease nursing students’ interest in clinical environments and has a negative correlation with their clinical performance.   Methods : This descriptive cross-sectional study is an attempt to compare nursing students'perception...

Introduction The development of methods to synchronize estrus in beef cattle has been refined to a point that is feasible as well as reasonable to obtain pregnancy rates in mixed populations of cycling and anestrous cows that exceed 50% to a single fixed-time artificial insemination, provided a progestin based estrus synchronization protocol is used (Lamb et al., 2001; Kojima et al., 2002; Perr...

A Senepol demonstration project was conducted on three commercial ranches in Paraguay starting in 1998. One calf crop was produced sired by 10 Senepol sires mated to native Zebu x British cows of varying percentages. A total of 337 calves were produced with a least one recorded measurement. Traits measured included birth, weaning and yearling weights as well as long yearling ultrasound fat thic...

Performance records from 1982 to 1992 on 1365 calves for birth weight (BW) and 1492 calves for weaning weight (WW) were analyzed to estimate relationships of purebred sire expected progeny difference (EPD) values for BW and W W to actual crossbred progeny performance. Sires of the calves were Polled Hereford, Simmental, Angus, Salers, Tarentaise, or Charolais. The pooled-across-breed regression...

The genetic traits of a purebred bull convey the reproductive and economic value to buyers. This study examines and compares the value of actual production weights (birth, weaning, and yearling weight), production expected progeny differences (EPDs) (birth, weaning, milk, and yearling), and ultrasound EPDs (carcass quality predictors) for purebred Angus bulls sold at auction. One EPD, birth wei...
