Inference for multivariate categorical data often proceeds by selecting a log-linear model from a set of competing models or, in a Bayesian approach, by averaging inferences over the set, weighted by posterior probabilities. In this paper, we use permutation invariance as a criterion for constructing a set of models for this purpose, for the common situation when the data form a ‘square’ contin...

Congestion in the transmission lines is one of the technical problems that appear particularly in the deregulated environment. The voltage stability issue gets more important because of heavy loading in this environment. The main factor causing instability is the inability of the power system to meet the demand for reactive power. This paper presents a new approach for alleviation congestion re...

This chapter proposes an analytic approach for the study of ICTs in contentious politics and human rights advocacy. By applying the analytical frames of contingency and hybridity to study design, this approach aims to promote empirical analyses, strengthen data comparability, and improve understanding into how human rights activists strategically combine digital and grounded communications to r...

The goal of contingency ranking is to provide a list possible critical situations and rank them according the severity their impact on power network. methods may be divided into two major categories: static dynamic techniques. Static approaches are fast can implemented in real-time, but they present different results depending parameter which has been selected for ranking. Dynamic methodologies...

Analysis and interpretation of behavior-environment relations are increasingly being conducted with data that have been derived descriptively. This paper provides an overview of the logic that underlies a sequential analytic approach to the analysis of descriptive data. Several methods for quantifying sequential relations are reviewed along with their strengths and weaknesses. Data from descrip...

We present the concept of organizational misfit as a complement to multi-contingency theory fit concepts for organizational performance. Firms with misfits have opportunity losses that firms without misfits do not suffer. Using data from 232 small and medium sized Danish firms, we confirm the hypotheses that firms with either or both situational and contingency misfits have lower performance in...
