“…The surface of spermatozoa is exposed directly to the epididymal fluid, and sperm plasma membrane undergoes significant changes during the passage. This process is called epididymal (post-testicular) maturation and covers changes in distribution of intramembraneous proteins or glycoproteins of testis origin, but some testicular proteins are also altered, masked, or replaced by proteins of epididymal origin [1,[5][6][7][8]. As a result of these modifications, the spermatozoa become motile and functionally competent cells capable of undergoing capacitation and binding to the zona pellucida, the extracellular coat surrounding the mammalian oocyte.…”

“…However, the use of OLS in this case, although a useful starting point, is inappropriate because the dependent variable is discrete rather than continuous. Instead, we argue below that a variation of the Ordered Probit model is the natural specification for such a study.Payne's findings support the widely held belief that Government youth training schemes are little more than a residual category for those young people unable to find a job and should not be regarded as an alternative to full time further education (for discussion see, for example, Raffe, 1988;Jones, 1988;White, 1988). On the other hand, Rice and McVicar (1996) argue that with the introduction of two year training schemes in the late 1980s and the greater emphasis placed on participants gaining vocational qualifications, these training schemes should be regarded as a closer substitute for full-time further education.…”

“…Simultaneously, therefore, YT both supported apprenticeships by providing subsidies and undermined them by providing a state-based alternative (Jones, 1988;.…”
