A synchronous generator may sometimes be able to withstand a large impact but it may fail to retain synchronism under a small impact due to growing oscillations, leading to instability. This is called dynamic instability. It occurs for specific operating conditions and network configurations, particularly in presence of fastacting excitation control. The paper presents techniques of small signa...

On the basis of the approach–avoid dynamics assumed by reactance theory (S. S. Brehm & J. W. Brehm, 1981) and other models (E. S. Knowles & J. A. Linn, 2004), it was predicted that interpersonal similarity can reduce reactance by increasing compliance and by reducing resistance. A communicator’s similarity to the participant was manipulated by identical first names and birthdays (Experiment 1) ...

The objective of this study was to establish the relationships between bioelectrical impedance analysis (BIA) measures (resistance and reactance) and temperature and to determine if corrections improve BIA models for brook trout Salvelinus fontinalis when used over a wide range of temperatures. Both resistance and reactance significantly decreased as temperature increased. Application of temper...

OBJECTIVE Recent developments in electrical impedance myography (EIM) have led to the use of handheld electrode arrays (HEAs) for data acquisition. Although preferable for several reasons, this approach tends to be more affected by subcutaneous fat (SF) than the original approach in which the impedance-measuring electrodes are widely spaced. In this study, we seek to identify the EIM parameter ...

This study examines how the types of language expression and message valence used by teachers to convey classroom-compliance instructions affect elementary-school children's psychological reactance their intention follow instructions. Altogether, 178 children (54% girls) participated in a mixed-design experiment. Participants read four self-developed cartoons, where hypothetical teacher conveye...

The current work explored the relations among reactance, regret, and behavioral choice. A possible mechanism for reactance in opposition to persuasion attempts involves people anticipating greater regret for negative outcomes after complying with an agent of persuasion than for negative outcomes after reacting against an agent of persuasion. Some participants were asked to anticipate regret pri...

The purpose was to show that when a favor reduces a person's freedom, it arouses "psychological reactance," a motivational state aimed at restoration of this freedom. Ss, run individually, learned they were to make Ist-imprcssion ratings of another S (confederate) and then were given a soft drink by this S, prior to making the ratings. In a 2 X 2 design, the Ist-imprcssion ratings were given lo...

In the present article a theory is outlined that explains why and when behavioral inhibition alters stimulus evaluations. In addition, some initial evidence is presented that supports the theory. Specifically, results of three experiments show that refraining from responding to stimuli results in devaluation of these stimuli, but only when these stimuli are positive. These findings suggest auto...
