Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
CORRELATED responses, or the associated changes of unselected characteristics which occur during artificial selection for a particular trait are due to environmental influences, genetic effects and a combination of the two. The theoretical aspects of correlated responses and procedures for the estimation of phenotypic, genetic and environmental correlations have been recently reviewed by Lerner (1958) and Falconer (1960). Although considerable research has been published on the growth of chickens, little is known about the associated changes which occur in unselected characteristics when artificial selection is made for growth to a particular age. Schnetzler (1936) found that two generations of selection for fast and slow growth to eight or nine weeks of age influenced adult body weight, egg weight and chick size. Maloney and Gilbreath (1962) observed that ten generations of selection in opposite directions for 12-week weight resulted in differences between the lines for 6-week weight, egg weight, age at…
