Recently, antiferroelectric and antiferroelectric‐like materials have regained interest in electronic devices, such as field‐effect transistors, memory, and transducers. Particularly in micro/nano‐electromechanical coupling systems such as actuators, these innovative materials, with their peculiar phase transition between antiferroelectric and ferroelectric phases, show promise in offering large electro‐strain, fast response, and low power consumption devices. However, compared to numerous computational models of ferroelectric actuators, numerical modeling of antiferroelectric and antiferroelectric‐like actuators remains relatively unexplored. In this paper, we propose a phenomenological model of uniaxial antiferroelectric and antiferroelectric‐like actuators based on their switching polarization behavior. Specifically, both the double hysteresis loop of antiferroelectric materials and the pinched hysteresis loop of antiferroelectric‐like materials can be captured by two hyperbolic tangent functions. This allows us to cast a polarization‐dependent strain and piezoelectric tensor into the constitutive laws. The proposed model is then implemented into a finite element framework, in which the voltage‐induced deformation can be solved using the Newton–Raphson procedure. Numerical examples of both antiferroelectric and antiferroelectric‐like actuators are illustrated and compared with experimental data, showing our proposed model can serve as a useful tool for the design and development of antiferroelectric and antiferroelectric‐like actuators.

Will increasing employee participation in reward decisions increase new product performance by first increasing a firm's level of market orientation? Literature offers limited insight to the effects of listening to employees regarding reward system design and whether this may influence market orientation implementation and new product performance. This paper provides research to fill the gap by examining the relationship between participation-based reward systems, market orientation, and new product performance. Based on expectancy theory, a conceptual model was developed suggesting that participation-based rewards will increase market orientation by considering employees' desires regarding performance rewards. To test the model, a mixed method was used to collect data. First, in-depth interviews were conducted with managers from 11 different firms to verify the proposed model. Then a multi-industry sample of managers from 290 firms was surveyed to maximize generalizability of the results. Data were analyzed using structural equation modeling techniques to simultaneously fit the measurement and structural models. The findings show that market orientation significantly impacts objective new product performance and mediates the relationship between participation-based rewards and objective new product performance. Participation-based rewards positively affect market orientation but surprisingly affect new product performance negatively, while positively moderating the relationship between market orientation and new product performance. The results suggest that managers should include employee input in designing reward systems. However, managers should also be careful of how much input they allow employees in determining their rewards and goals as more input will improve market orientation or responding to information collected by, and disseminated throughout the firm, and that, in turn, will improve some types of new product performance. However, the direct effect of employee input can decrease new product performance suggesting that there may be a trade-off between various success measures of new products developed and introduced by the firm.
