This chapter examines the book's theory further by using fuzzy-set qualitative comparative analysis methods, which test for necessary and sufficient causal relationships using the logic of set theory. The data confirm the hypothesis that both the petroleum deficit and the threat to imports must be substantial to trigger anticipatory strategies. Thus, the results reinforce the findings from the previous chapters that coercive vulnerability, as determined by the petroleum deficit and import disruption threat, spurs great powers to adopt anticipatory strategies to reduce the danger of oil coercion. Moreover, the severity of the strategy chosen is consistent with the level of coercive vulnerability faced by the state. The more extreme the deficit and import disruption threat, the more extreme the strategy chosen; the less extreme the deficit and threat, the less extreme the strategy chosen.

AbstractThe main lines ofthe program designed for the interpretation of ECGs, developed in Padova by LADSEB-CNR with the cooperation of the Medical School of the University of Padova are described. In particular, the strategies used for (i) morphology recognition, (ii) measurement evaluation, and (iii) linguistic decision making are illustrated. The main aspect which discerns this program in comparison with other approaches to computerized electrocardiography is its ability of managing the imprecision in both the measurements and the medical knowledge through the use of fuzzy-set methodologies. So-called possibility distributions are used to represent ill-defined parameters as well as threshold limits for diagnostic criteria. In this way, smooth conclusions are derived when the evidence does not support a crisp decision. The influence of the CSE project on the evolution of the Padova program is illustrated.

Empirical tests of the application of computer record linkage methods versus the use of routine clerical searching, for bringing together various vital and ill-health records, have shown that the success rate for the computer operation was higher (98.3 versus 96.7 per cent) and the proportion of false linkages very much lower (0.1 versus 2.3 per cent). The rate at which the ill-health records were processed by the computer was approximately 14,000 per minute of central processor time, representing a cost of a half a cent apiece.Factors affecting the speed, accuracy and cost of computerized record linkage are discussed.

This study aims to develop a performance assessment instrument for Make up Training Subject in Beauty Education Program by appropriate validity and reliability procedure in thedevelopment of the assessment instrument as the assessment process and products. Thisresearch is a development research (R&D). The research focuses on the development ofassessment instrument for Makeup Training Subject. The aspects of research, data sources, techniques and instruments/data collection instrument, and validation and reliability of theinstrument used in the study conducted by interview, observation, and literature and documents.The data of this study is quantitative data, which was statistically analyzed due to relevant empirical testing (validation of instruments) that includes testing and content validity andinternal validity. Descriptive analyzes were undertaken to describe the research data. The results showed: 1) The design of the instrument Makeup Training Subject are developed through theneeds analysis. It is done through literature review and study of the course competencies byengaging a team of researchers. This study resulted in the instrument guidelines and assessment instrument completed with its scoring rubrics. The instrument comprising: a step of validityassessment is done through the stages: experts judgment, empirical tests to prove the validityand reliability of the instruments assessment. All the performance test instrument developed is
