Exploring the Fluctuations of Foreign Language Enjoyment in Conversation: An Idiodynamic Perspective     

Majid Elahi Shirvan  Nahid Talebzadeh 《Journal of Intercultural Communication Research》2018,47(1):21-37

The main focus of this study was to discern the effect of different topics on the dynamics of one of the main variables of positive psychology, foreign language enjoyment (FLE). To do this, we used an idiodynamic method to explore the rapid moment-to-moment changes of FLE. Seven female university students engaged in a conversation involving both simple and difficult topics, and self-rated their moments of experiencing enjoyment during the conversation process. The results indicate that the dynamicity of enjoyment emerges not only within individuals, but also across individuals intra-personally under the influence of conversational topics. Furthermore, the idiodynamic method provided us with the opportunity to examine the underlying factors of the dynamic fluctuations of FLE and gain a deeper insight into FLE as a dynamic system.  相似文献

讨论了正项级数的两种判别法：比值判别法和根值判别法，以及两者的关系，得出凡是可用比值判别法的正项级数必能用根值判别法，逆命题不成立，根据具体问题的特点采用不同的方法，解题得难以程度不同。  相似文献   

支持型组织责任对员工创新行为的影响——有调节的中介效应模型检验     

张毅  黄福华 《软科学》2016,(7):94-98

引入积极情绪、供给需求匹配作为中间变量,建立支持型组织责任影响员工创新行为的有调节的中介效应模型。实证研究结果显示,支持型组织责任对员工创新行为具有积极的正向影响,其效用受到供给需求匹配的调节;人际支持完全通过个体积极情绪来影响员工创新行为,组织支持对员工创新行为的影响部分受到个体积极情绪的中介;积极情绪对员工创新行为的影响受到供给需求匹配的调节,研究结论有效地解释了以往研究的分歧。  相似文献

Through the Dąbrowski Lens: A Fresh Examination of the Theory of Positive Disintegration     

Amanda Harper  Linley Cornish  Susen Smith  Peter Merrotsy 《Roeper Review》2017,39(1):37-43

D?browski’s theory of positive disintegration is an emotion-centered, nonontogenetic, five-level theory of personality development where the experience of all emotions is essential for the process of growth. In this article, we examine the complexities of the three factors of development, which are essential to the notion of development within the theory of positive disintegration. We elaborate on the relationships between these factors, depict the processes and interactions in a new graphical framework, provide associated explanations, and support these by additional references to D?browski’s original writings.  相似文献   

Hopes for the future: demographic and personal resources associated with self-perceived employability and actual employment among senior year students     

Jonathan Kasler  Leehu Zysberg  Nofar Harel 《Journal of Education & Work》2017,30(8):881-892

Undergraduates approaching completion of their studies may embrace the prospect of entry into the world of work as a challenge or conversely, may view it with trepidation. This study explores three major personal resources that may be associated with how young undergraduates view their future employability: perceived hope, grit and emotional intelligence. Demographics associated in the literature with perceived chance of employment – gender, age and having a learning disability – were also included in the study. The participants were college students in their senior year (n = 584), studying in a variety of undergraduate programmes. Results show that perceived hope and grit were positively associated with perceived employability whereas the relationship with emotional intelligence was more complex. None of the demographics associated with perceived employability.  相似文献
