Injustice in School and Students’ Emotions, Well-Being, and Behavior: A Longitudinal study

Abstract: School can be regarded as an important factor in the development of children’s values and attitudes. Given this great importance of justice experiences for students’ development, this study aimed at examining the influence of perceived injustice in school on students’ emotions, well-being, and behavior with an experimental longitudinal design. In total, 196 students participated in this study and came to the university with their classes to receive extra teaching once a week for six consecutive weeks. To manipulate justice perceptions, a scenario of arbitrary privilege was chosen to lead students of the experimental group to experience injustice from a beneficiary perspective. We found that students in the experimental group reported higher well-being and a higher appreciation of the opportunity to learn than the control group did. Additionally, they showed an increase in justice-related negative emotions over time; that is, they expressed more of a bad conscience and stronger feelings of anger the more they became aware of their privilege. This study shows that even subtle experiences of injustice in school can have an impact on students’ outcomes. These results are discussed with regard to practical implications.

Industrial truck having increased static or quasi-static tipping stability

Abstract: A forward-control counterweight fork-lift truck has a liftable and tiltable load-lifting device (1), a traction drive and operating drives for the movement of the load-lifting device (1). A calculation model (D) is stored in a control device (SE), to which directly or indirectly acting sensors (S) are connected for detecting the lifting load (L), the lifting height (H), the tilting angle (WM), the load torque (M), the direction of travel (R), the driving speed (V), and the steering angle (WL). The control device (SE) is designed to determine a driving and load state (Z) based on the detected physical variables (L, H, WM, M, R, V, WL) and the stored calculation model (D) and is operatively connected to the traction drive and the operating drives. Depending on the driving and load state (Z) determined, the operating speed, starting and braking acceleration, and driving speed are each reduced.

Device for cooling components by means of hydraulic fluid from a hydraulic circuit

Abstract: The invention relates to a device for cooling at least one component by hydraulic fluid from a hydraulic circuit. The hydraulic circuit includes a hydraulic pump, at least one user of hydraulic energy, and a reservoir. The component is connected into the hydraulic circuit between a heat exchanger and the intake side of the pump. The component is connected into a suction line that connects the reservoir with the pump. Between the component and the pump there is a control valve connected on the output side to a bypass suction line connected with the reservoir. In a first position of the control valve, the suction line is closed and the bypass suction line is open. In a second position of the control valve, the suction line is at least partly open. The heat exchanger can be connected into the suction line or into the return line.

Using Multivariate Statistics

Abstract: Thank you for downloading using multivariate statistics. As you may know, people have look hundreds times for their favorite novels like this using multivariate statistics, but end up in infectious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they juggled with some harmful bugs inside their laptop. using multivariate statistics is available in our digital library an online access to it is set as public so you can download it instantly. Our books collection saves in multiple locations, allowing you to get the most less latency time to download any of our books like this one. Merely said, the using multivariate statistics is universally compatible with any devices to read.

Multimedia in Learning

Abstract: A wide variety of media can be used in learning, including distance learning, such as print, lectures, conference sections, tutors, pictures, video, sound, and computers. Any one instance of distance learning will make choices among these media, perhaps using several.
