How U.S. and Chinese journalists think about plagiarism

A comparison of 1,096 professional journalists in China and the United States on attitudes toward attribution and plagiarism reveals Chinese journalists were more likely to see attribution as a practice to be embraced regardless of career longevity and culture, suggesting journalistic norms are more important than a collectivist orientation. Attribution was more likely to be embraced by those who see principles as more important than expediency, affirming research that plagiarism is hardly a monolithic concept. Overall, journalists in the two nations did not vary significantly in their attitudes toward plagiarism, despite vast differences in culture and politics as well as evidence that in some other fields China is more accepting of reusing material without attribution. The data show that among journalists, attitudes toward plagiarism are shared across national boundaries, reinforcing related research showing that a journalism culture exists and is shared at least in part across national boundaries.     

运用数学运算技巧突破学习物理的数学障碍

1单位换算及幂的运算单位换算,依据的是等量代换的思想。较大或较小的数常用科学计数法的形式表示,这需要熟练运用幂的运算。例152km=cm。常见的错误是:①52km=52×106km=…。②52km=52km×105cm=…。上面式子中,52km与52×105km和52km×105cm是不相等的。违反了等量代换的原则。在×105之后,单位不该是km,应该是cm。正确的过程是:因为1km=105cm,所以52km=52×1km=52×105cm=5.2×108cm。例26.4×105g=kg。常见的错误是:6.4×105g=640000×0.001kg=…由此可见,有的同学非常不习惯科学计数法的运用,很容易出现计算错误。其实掌握科学计数法的…

Cyclic-anion salt for high-voltage stable potassium-metal batteries

Electrolyte anions are critical for achieving high-voltage stable potassium-metal batteries (PMBs). However, the common anions cannot simultaneously prevent the formation of ‘dead K’ and the corrosion of Al current collector, resulting in poor cycling stability. Here, we demonstrate cyclic anion of hexafluoropropane-1,3-disulfonimide-based electrolytes that can mitigate the ‘dead K’ and remarkably enhance the high-voltage stability of PMBs. Particularly, even using low salt concentration (0.8 M) and additive-free carbonate-based electrolytes, the PMBs with a high-voltage polyanion cathode (4.4 V) also exhibit excellent cycling stability of 200 cycles with a good capacity retention of 83%. This noticeable electrochemical performance is due to the highly efficient passivation ability of the cyclic anions on both anode and cathode surfaces. This cyclic-anion-based electrolyte design strategy is also suitable for lithium and sodium-metal battery technologies.
