From climate change victims to climate change actors: The role of eco-parenting in building mitigation and adaptation capacities in children

Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts.     

An Informetric Investigation into the Potential for Change in Belgian Art Education at the Beginning of the Twentieth Century

The beginning of the twentieth century was a period of pedagogical enthusiasm and renewal in the field of education. Based on a list of articles concerning art education published in Belgian periodicals between 1903 and 1923, the author undertakes an analysis of the title words in order to study how the subject was able to evolve. For this purpose, the pertinent title words are grouped into content categories. It can be seen that these content categories demonstrate specificity compared to other periods. The specificity of the subject at a given moment implies that the transformation of the subject consists of the emergence, the decline or the exchange of categories, which can also be demonstrated. The connections of these variations to historical facts are substantiated. It can therefore be stated that these variations represent the historical evolution of the subject. However, such emergence, decline and exchange of categories is only possible on condition that each category is able to vary independently of the others. This is shown by an autonomy index as well as by an 2‐test. Thus, art education did not drop from the sky as a ready‐to‐teach school subject. Art education is always what the people make of it, which makes reflection on what it could be or has to be so important at any given moment too.     

唐代上层社会妇女婚姻地位探析

唐代上层社会妇女的婚姻生活仍然局限在择偶不自主、生育无节制的传统樊篱内,且忍受着一夫一妻多妾制给女性心灵带来的深刻痛苦,并未如人们想象的那样开放、自由,而且由于从一而终的封建伦理道德对心灵的禁锢,虽然政府对离婚和再嫁有了宽松规定,也并未有多少人身体力行。

Non-linear 2-DOF model and centre manifold theory to study limit cycle oscillations caused by drum-brake judder

This paper presents the research on the laws of systematic-parameter dependent variation in the vibration amplitude of drum-brake limit cycle oscillations (LCO). We established a two-degree non-linear dynamic model to describe the low-frequency vibration of the drum brake, applied the centre manifold theory to simplify the system, and obtained the LCO amplitude by calculating the normal form of the simplified system at the Hopf bifurcation point. It is indicated that when the friction coefficient is smaller than the friction coefficient at the bifurcation point, the amplitude decreases; whereas with a friction coefficient larger than the friction coefficient of bifurcation point, LCO occurs. The results suggest that it is applicable to suppress the LCO amplitude by changing systematic parameters, and thus improve the safety and ride comfort when applying brake. These findings can be applied to guiding the design of drum brakes.     

关于粘性导数的几个性质的探讨

M .G .Crandall等人在文 [1]中给出了函数的粘性导数的概念。在这个概念的基础上我们讨论了函数的粘性导数的上 (下 )导集的几个性质 :在函数可微点处的性质、闭凸性质、与C1类函数的和的性质、与C2 类函数的差在严格局部极大 (小 )值点的性质。
