Emotion and cognition have long been considered as two influential factors determining the quality of teaching and learning. They form the foundation of all aspects of teaching as an emotional and thought-provoking profession. With the advent of Positive Psychology and affective pedagogy, now English as a Foreign Language teachers’ inner states and emotions are placed at the center of every educational program all around the world. This consideration has led to a rise in various domains of teaching and teacher education. (...) However, the interactive influence and association between teachers’ emotions and cognitions concerning their pedagogical practices has been mostly left ignored in EFL contexts. To fill this gap, the present study aimed to offer a mini-review of the concepts, definitions, related theories, and empirical evidence in this line of research. It also presented practical implications for different stakeholders together with research gaps and future directions for enthusiastic L2 investigators. (shrink)

Previous studies have shown that the color red can affect basic motor functioning. However, these studies utilized simple gross motor tasks rather than those assessing complex fine motor skills. Moreover, these empirical studies were theoretically based on the threat–behavior link in human and non-human animals, and neglected the relationship between arousal and motor performance. According to the Yerkes–Dodson law and the inverted-U hypothesis in sport psychology, for simple motor tasks, high arousal is more advantageous than low arousal ; for complex (...) motor tasks, low arousal is more advantageous than high arousal. The current research examined the effect of color on different kinds of motor skills based on the inverted U-hypothesis. In Experiment 1, we examined the effect of red and blue on dart-throwing performance, whereas in Experiment 2, we examined the effect of red and blue on grip strength performance. The results showed that performance of fine motor skill in the blue condition was better than in the red condition, and performance of gross motor skill in the red context was better than in the blue context. These results indicate that the type of motor skill assessed moderates the influence of red and blue on motor performance. (shrink)

This paper aims at investigating the dynamic characteristics of a microring driven by dual arch electrodes because they are basic elements of microelectrostatic motors. The dual arch electrodes surround the periphery of the microring and are arranged symmetrically to the center of the ring. The electrodes are fixed while the microring is flexible. The electrostatic force will deform the microring, while the deflection of the microring changes the gap between the microring and the electrodes, thereby changing the electrostatic force. Therefore, (...) this is an electromechanical coupling effect. The nonlinear partial-differential equation that governs the motion of the microring is derived based on thin shell theory. Then, based on the assumption of small deflection, the nonlinear governing equation is linearized by truncating the higher-order terms of the Taylor series expansion of the nonlinear electrostatic force. After that, the linearized governing equation is discretized into a set of ordinary differential equations using Galerkin method in which the mode shape functions of the ring are adopted. The influences of the structural damping of the microring and the span of the arch electrodes on the forced response and dynamical stabilities of the microring are investigated. The results show that the damping ratio has a great influence on the system instability during high-frequency excitation. The unstable region of the system can increase with the increase of the electrode span; the response amplitude can also be increased within a certain range. (shrink)

In recent years, precise high flow oxygen therapy as a new type of oxygen therapy machine has gradually attracted people’s attention and has been widely used in hospital emergency and clinical treatment of respiratory diseases; especially in recent years, severe coronavirus disease has played an important role in the treatment of patients. This paper presents a new type of precise high flow oxygen therapy machine with electromagnetic pneumatic flow valve as the core control element. A sliding mode control strategy based (...) on the system is proposed to realize the accurate control of oxygen concentration and output flow of oxygen therapy mixture. The physical equipment of the precision high flow system is established, and its working performance is verified through the test platform. The optimization design goal of the precision high flow equipment is achieved. (shrink)

Learners’ willingness to communicate in a foreign language is regarded as a critical issue in educational contexts, so the role of emotional factors in learners’ willingness to communicate has drawn the attention of investigators. This review investigated the studies on the relationship between English as a Foreign Language learners’ grit, foreign language anxiety, and willingness to communicate. This review showed a significant relationship between learners’ grit and willingness to communicate. The earlier studies showed that gritty learners with incessant inspiring efforts (...) are more likely to communicate in a foreign language. This review also indicated that lower anxious learners tend to have more willingness to communicate. Earlier studies also indicated that the theories, such as broaden-and-build, positive psychology, dynamic system, affective filter, and attentional control can justify the relationships between these constructs. Moreover, the study has some pedagogical implications and suggestions for teachers, learners, syllabus designers, material developers, teacher educators, policy-makers, and advisors. The ideas can improve their awareness of teachers’ willingness to communicate, grit, and foreign language anxiety in educational environments. (shrink)
