Adapted from the Early Childhood Environment Rating Scale–Revised, the Chinese Early Childhood Program Rating Scale (CECPRS) is a culturally comparable measure for assessing the quality of early childhood education and care programs in the Chinese cultural/social contexts. In this study, 176 kindergarten classrooms were rated with CECPRS on eight dimensions of program quality. Multivariate gene...

a wind farm is a collection of wind turbines built in an area to provide electricity. wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. in this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in hl1 level is proposed. in proposed procedure, application of fuzzy – markov f...

For some years, the limits of classic reliability theory have been recognized in favor of the Generalizability Theory, which deals simultaneously with multiple sources of error. This measurement model can be particularly useful when applied to research in cognitive psychophysiology. Indeed, studies in this field often deal with estimated measures whose reliability is rarely taken into account. ...

Promise of Software Components In engineering design, the idea of aggregating standardized components to create a complex system has allowed engineers to create better systems more easily. Components are described in a handbook, where each has a “data sheet” entry. Its data sheet describes what a component does, and equally important, it gives constraints that allow the system designer to decid...

The critical reactions of Bentler (2009, doi:10.1007/s11336-008-9100-1), Green and Yang (2009a, doi:10.1007/s11336-008-9098-4; 2009b, doi:10.1007/s11336-008-9099-3), and Revelle and Zinbarg (2009, doi:10.1007/s11336-008-9102-z) to Sijtsma's (2009, doi:10.1007/s11336-008-9101-0) paper on Cronbach's alpha are addressed. The dissemination of psychometric knowledge among substantive researchers is ...

The structure function φ of a binary monotone system is assumed to be known and given in a disjunctive normal form, i.e. as the logical union of products of the indicator variables of the states of its subsystems. Based on this representation of φ, an improved Abraham algorithm is proposed for generating the disjoint sum form of φ. This form is the base for subsequent numerical reliability calc...

We introduce the entropy function in order to study the reliability and repairability of systems. In detail we establish the explicit relationships between reliability and repairability; then we calculate the decay of a system due to its regular running.

This paper deals with the use of Bayesian networks to compute system reliability. The reliability analysis problem is described and the usual methods for quantitative reliability analysis are presented within a case study. Some drawbacks that justify the use of Bayesian networks are identified. The basic concepts of the Bayesian networks application to reliability analysis are introduced and a ...

Most software-component research has been directed at functional specification of software components. The other, equally important, side of the coin is component quality. We present a foundational theory of reliability based on components. The theory describes in principle how component developers can make measurements that are later used by system designers to calculate — without implementati...
