Frontiers | The Sunny Side of Negative Feedback: Negative Feedback Enhances One's Motivation to Win in Another Activity

Negative feedback has been widely reported to be a demotivator that could frustrate the recipient’s need for competence and erode his intrinsic motivation in the same activity. Nevertheless, little attention has been devoted to the intertemporal effect of negative feedback on one’s intrinsic motivation in another activity. To fill this gap, we arranged participants in a game with two sessions and manipulated the content of feedback as a between-subject factor. In Session 1, participants had to complete a time estimation task with moderate difficulty, during which half of the participants received normal performance feedback and the other half received negative performance feedback. In Session 2, all participants were guided to accomplish a moderately difficult stopwatch task that was competence-supportive. A more pronounced win-loss difference wave of reward positivity (RewP) was detected in the experimental (negative performance feedback) group compared to the control (normal perf ....

Study: 25 mega-cities produce more than half the world's urban greenhouse gas emissions

According to research from China, 25 mega-cities are responsible for more than half of the world s urban greenhouse gas emissions. Cities in China, as well as in Japan and Russia, are notably singled out in the study.
Global greenhouse gas emissions are largely being driven by a small fraction of cities, according to a new study by researchers from China s Sun Yat-sen University and the Guangdong Provincial Key Laboratory of Environmental Pollution Control and Remediation Technology in Guangzhou.
The research reveals that, among 167 cities studied, more than 50% of urban greenhouse gas emissions are emitted by 25 very large cities. Among these are 23 Chinese cities – including Shanghai, Beijing and Handan – as well as Tokyo and Moscow. ....

Polarization control is essential for tailoring light-matter interactions and is the foundation for many applications such as polarization imaging, nonlinear optics, data storage, and information multiplexing. A linear polarizer, which is a polarization optical element that filters a specific linear polarization from unpolarized light, plays an important role in both polarization generation and manipulation. However, the generation of arbitrary polarization states other than linear polarization usually requires cascading of multiple optical polarization elements, including both linear polarizers and wavepla ....
