The Effect of Childbirth on Hiatal Dimensions
Obstetrics & Gynecology, 2009To estimate changes in levator hiatal dimensions after childbirth in women with and without ultrasonographically visible morphological abnormalities of the levator ani and to correlate those changes with delivery mode.A total of 296 nulliparous women were recruited.

Correspondence Principles for Effective Dimensions [PDF]
We show that the classical Hausdorff and constructive dimensions of any union of $\Pi^0_1$-definable sets of binary sequences are equal. If the union is effective, that is, the set of sequences is $\Sigma^0_2$-definable, then the computable dimension also equals the Hausdorff dimension.

Dimensions of Local Union Effectiveness
ILR Review, 1993The authors develop a model of union effectiveness based on an analysis of organizational goals and use it to interpret data on 511 teachers' union locals in Pennsylvania. A factor analysis identifies five dimensions of union effectiveness in the locals: the quality or extent of (a) member participation, (b) the union's preparations for negotiations, (

On the Effects of Dimension in Discriminant Analysis
Technometrics, 1976Given fixed numbers of labeled objects on which training data can be obtained, how many variables should be used for a particular discriminant algorithm? This, of course, cannot be answeredin general since it depends on the characteristics of the populations, the sample sizes, and the algorithm.

The truth about the effective dimension
Statistica Neerlandica, 2018The effective dimension of a model is a useful measure of its complexity. In linear models, the trace of the so‐called hat matrix is a convenient choice. It has strong links to variance estimation in mixed models, and it suggests straightforward partial effective dimensions for additive model components. Efron (2004) casts doubt on the trace of the hat

Intrauterine Hormone Effects on Tooth Dimensions
Journal of Dental Research, 2013The human dentition is a complex adaptive system that is influenced by genetic, epigenetic, and environmental factors. Within this system, is sexual dimorphism related to the growth promotion of the Y chromosome, or to hormonal influences, or both? This study is the first to investigate both primary and permanent tooth sizes in females from opposite ...

Effectiveness Dimension of Performance
2014The two components of health care facility performance, efficiency and effectiveness (quality), were introduced in Chap. 1. In this chapter, a closer examination of the effectiveness component is provided. Sherman and Zhu (2006) introduce quality-adjusted DEA applied to bank branches.

Dimensions of Teaching Effectiveness
The Journal of Experimental Education, 1976ABSTRACTForty-one semantic differential scales measuring the concept of a good teacher were factor analyzed to assess the general, underlying judgmental dimensions which students use in evaluating effectiveness in teaching. Both high school and college students judged teachers on the dimensions of student/teacher rapport, communicative style ...

Measuring the Dimensions of Effective Fathering
Educational and Psychological Measurement, 1994Data were collected on a general sample of 1,650 fathers and a group of 42 effective fathers. Items that differentiated between the general sample and the effective-fathers group were subjected to factor analysis and other psychometric studies resulting in the development of seven internally consistent scales measuring dimensions such as commitment ...
