[4] Factor XII: Hageman factor

1993
Publisher Summary This chapter discusses the factor XII that is the Hageman factor. The functional activity of factor XII or factor XIIa can be determined via the correction of the abnormal clotting time of human factor XII-deficient plasma by comparing the times obtained through the addition of pooled normal plasma (PNP).

[7] Factor VIII and factor VIIIa

1993
Publisher Summary This chapter focuses on the role of factor VIII and factor VIIIa present in blood. The factor VIIIa apparently alters the active site structure of factor IXa to make it recognize the rate-limiting transition state for factor X activation, because its dominant kinetic effect is to increase the kcat.

The standards factor

ACM SIGCHI Bulletin, 1989
As the newly-appointed SIGCHI Standards Liaison, I hope to continue in the fine tradition established by Jon Meads over the past several years. As I see it, my primary task is to inform SIGCHI members about any standards activities that may affect them as designers and users of interactive software.

FACTOR INTERACTION IN NONLINEAR FACTOR ANALYSIS

British Journal of Mathematical and Statistical Psychology, 1967
Factor interaction models are defined as those cases in nonlinear factor analysis in which the specification equation contains products of two or more latent variables or functions of latent variables. A complete algebraic treatment is given for the case of a product of two latent variables, and certain more general cases are briefly outlined.

The Y Factor

The Christian Librarian, 2000
The Sabbath issue is finished. Now it is time to take a rest (pun intended). I probably benefited from my study of the issue more than any of you, but that is what I love about education-there is so much to learn. In "The Y Factor," I usually focus on the noun in the title of this journal, addressing issues of librarianship.
