Selection Technologies (selection + technology)
Selected AbstractsTWENTY-FIRST CENTURY PINK OR BLUE: HOW SEX SELECTION TECHNOLOGY FACILITATES GENDERCIDE AND WHAT WE CAN DO ABOUT ITFAMILY COURT REVIEW, Issue 1 2008Monica Sharma In the midst of a genetic revolution in medicine, Assisted Reproductive Technology (ART) has become a well-established technique to help infertile women achieve pregnancy. But many women are now turning to ART not just to circumvent infertility, but consciously to shape their families by determining the sex of their children. Many patriarchal cultures have a gender preference for males and to date have used technological advances in reproductive medicine to predetermine the sex of the child being born. Women have sought sex-selective abortions, where the pregnancy was being terminated solely on the basis of the sex of the unborn fetus. The combination of ART advances and gender preference has led to the disappearance of at least 100 million girls from the world's population leading to a mass gendercide. This article examines the societal impact of unbalanced gender ratios and the need to regulate sex selection to avoid nations of bachelors. [source] Stubborn Reliance on Intuition and Subjectivity in Employee SelectionINDUSTRIAL AND ORGANIZATIONAL PSYCHOLOGY, Issue 3 2008SCOTT HIGHHOUSE The focus of this article is on implicit beliefs that inhibit adoption of selection decision aids (e.g., paper-and-pencil tests, structured interviews, mechanical combination of predictors). Understanding these beliefs is just as important as understanding organizational constraints to the adoption of selection technologies and may be more useful for informing the design of successful interventions. One of these is the implicit belief that it is theoretically possible to achieve near-perfect precision in predicting performance on the job. That is, people have an inherent resistance to analytical approaches to selection because they fail to view selection as probabilistic and subject to error. Another is the implicit belief that prediction of human behavior is improved through experience. This myth of expertise results in an overreliance on intuition and a reluctance to undermine one's own credibility by using a selection decision aid.

Goldstein [source] N-linked glycosylation is an important parameter for optimal selection of cell lines producing biopharmaceutical human IgGBIOTECHNOLOGY PROGRESS, Issue 1 2009Patrick H. C. van Berkel Abstract We studied the variations in N-linked glycosylation of human IgG molecules derived from 105 different stable cell lines each expressing one of the six different antibodies. Antibody expression was based on glutamine synthetase selection technology in suspension growing CHO-K1SV cells. The glycans detected on the Fc fragment were mainly of the core-fucosylated complex type containing zero or one galactose and little to no sialic acid. The glycosylation was highly consistent for the same cell line when grown multiple times, indicating the robustness of the production and glycan analysis procedure. However, a twofold to threefold difference was observed in the level of galactosylation and/or non-core-fucosylation between the 105 different cell lines, suggesting clone-to-clone variation. These differences may change the Fc-mediated effector functions by such antibodies. Large variation was also observed in the oligomannose-5 glycan content, which, when present, may lead to undesired rapid clearance of the antibody in vivo. Statistically significant differences were noticed between the various glycan parameters for the six different antibodies, indicating that the variable domains and/or light chain isotype influence Fc glycosylation. The glycosylation altered when batch production in shaker was changed to fed-batch production in bioreactor, but was consistent again when the process was scaled from 400 to 5,000 L. Taken together, the observed clone-to-clone glycosylation variation but batch-to-batch consistency provides a rationale for selection of optimal production cell lines for large-scale manufacturing of biopharmaceutical human IgG. © 2009 American Institute of Chemical Engineers Biotechnol.
