Boronising of steels is a hardening process to get high surface hardness. The erosion resistance of boronised steels was researched with the use of four kinds of erodent, i.e. glass, alumina, quartz and silicon carbide. The erosion rate increases rapidly with erodent hardness and severe erosion occurs with high impacting angle range of hard particles. SEM analysis indicated that chipping is caused by repetitive impacting of glass and quartz, whereas by alumina and silicon carbide impacting, chipping, and that plastic flow take place simultaneously and the erosion rate reaches the peak value when the impacting angle is above 60°. 相似文献
This paper provides the opportunity to understand children’s behavior from a memory viewpoint. For the last three decades, cognitive developmentalists have been asking the question, “what develops in children’s memory?” Four answers to this question are presented, complete with explanations, examples, and possible applications where appropriate. The purpose of the paper is to provide early childhood educators and other practitioners who work with children a different lens through which to view children’s behavior. The memory view is compatible with current best practices in early childhood education, and may provide practitioners an additional viewpoint from which to draw when implementing developmentally appropriate practice. 相似文献
Purpose: This study attempts to close the research gap created by the fact that existing studies neglect the problem of how effectively agricultural professors from different European countries communicate. The aim is to identify similarities and differences in the numbers of agricultural professors perceived by students as engaging in verbal and nonverbal immediacy communication.
Methodology: An online survey was conducted among students of agricultural universities from Austria, Slovenia and Albania.
Findings: The results show that professors of agriculture from Austria, Slovenia and Albania should generally not be satisfied with their own communication patterns and should thus try to improve their communication. The result also reveals cultural differences in the shares of agriculture professors employing different communication patterns in Austria, Slovenia and Albania. Compared to Austrian and Slovenian students, their Albanian peers perceive that most of their professors use nonverbal immediacy communication. According to Austrian students, the majority of their professors use verbal immediacy. On the contrary, Albanian students assessed that some of their professors employ verbal immediacy.
Practical Implications: The results show the professors of agriculture should improve the way they communicate to students. In particular, the Albanian professors should improve their verbal communication especially in terms of providing timely and quality feedback to students.
Theoretical implications: The study reveals differences in immediacy communication among countries (Austria, Slovenia and Albania) which the scientific literature considers to have a high-context culture.
Originality/Value: Given that no study has yet examined how students perceive professors’ communication in different European countries, this research helps understand the characteristics of agricultural professors’ communication. 相似文献
Following the presentation of a marketing management paradigm for higher educational institutions, this paper discuses some aspects of the pricing policy process in colleges and universities. A statistical model of the college choice process is developed, and some empirical results related to the effects of price, among other factors, on the collegechoice decision-making behavior process of high school seniors are presented and interpreted. The two most important factors affecting the college choice process are seen to be college quality and price-related considerations. Marketing implications of these results are discussed.Presented at the Annual Forum of the Association For Institutional Research, Houston, Texas, May 1978. 相似文献
