Abstract： The Leader-Member Exchange (LMX) relationship within organizations is dynamic, evolving over time and in response to key events. However, existing research lacks an in-depth exploration of the dynamic nature of LMX development and the mechanisms through which events drive these changes. This study aims to address this gap by investigating the key events that influence shifts in LMX quality, systematically analyzing the antecedents and potential mechanisms underlying the dynamics of LMX relationships. The study will employ a deductive approach coupled with qualitative methods to identify fundamental trends in LMX evolution and pinpoint the key events that instigate these transformations. Subsequently, building on the initial exploration of LMX dynamics and their triggers, the study will conduct empirical research to track the developmental changes in LMX at different stages. Specifically, during the establishing phase of LMX, emphasis will be placed on interactions between employees and leaders, exploring the process of LMX establishment and development for new employees. In the routinization phase of LMX, the study will investigate significant internal and external events that drive further changes in LMX, examining the patterns of LMX evolution through event analysis. By anchoring the research in critical events, a theoretical framework for understanding the dynamic shifts in LMX will be developed, offering practical insights and recommendations for managers and team management practices.

Abstract： In the process of reading, readers mainly obtain information through the fovea region—in particular, the parafovea plays an important role in information acquisition. Readers can obtain certain information from the parafovea through previewing processing, thus promoting the improvement of reading efficiency, which is called the “previewing effect”. The effect of the processing load of the fovea on the previewing effect of parafovea has become a popular research focus of late. For example, studies based on alphabetic languages have found that the previewing effect of the parafovea is greater for high-frequency and short words than for low-frequency and the long words. While Tibetan is an analphabetic language, it also belongs to the Sino-Tibetan language family and has many similarities with Chinese. However, it is still largely unclear how to reflect the above role in the process of Tibetan reading. Will it only show the common characters of alphabetic languages or will it show some Chinese characteristics? The present study aimed to provide experimental evidence to respond to these research questions. Two experiments were carried out on 119 Tibetan undergraduate students. More specifically, participants were asked to read Tibetan sentences and their eye movements during reading were recorded using an SR Research EyeLink 1000Plus eye tracker (sampling rate = 1000 Hz). Experiment 1 manipulated the fovea word frequency (i.e., high vs. low frequency) to investigate the word frequency effect and word frequency delay effect of fovea words in Tibetan reading. The results showed a word frequency effect and a word frequency delay effect in Tibetan reading. Experiment 2 manipulated both fovea word frequency and parafovea previewing word types with the aid of boundary paradigm to investigate the previewing effect of parafovea and the effect of fovea word frequency on the previewing effect of parafovea in Tibetan reading. The results showed a previewing effect of parafovea in Tibetan reading and that, when compared with low-frequency fovea words, high-frequency fovea words had a greater promoting effect on the previewing effect of parafovea. The primary findings can be summarized as follows: (1)significant word frequency effect exists in Tibetan reading, which is reflected in the whole process of vocabulary processing; (2)there is a significant word frequency delay effect in Tibetan reading, which runs through the whole process of vocabulary processing; (3)there is a significant previewing effect of parafovea in Tibetan reading, through which the reader can extract speech and font information; and(4)in Tibetan reading, fovea word frequency affects the size of the previewing effect of parafovea—moreover, word frequency only affects the extraction of shape previewing information in the early stage of lexical processing, that is, the previewing effect of high-frequency words is greater under the condition of shape previewing. In conclusion, the effect of the processing load of the fovea on the previewing effect of parafovea shows the common characteristics of alphabetic languages in Tibetan reading. In addition, this study found that reading Tibetan involves the word frequency delay effect and the previewing effect of parafovea; these findings support the theory of parafovea sequence processing in the E-Z reader model.

Abstract： Poverty remains one of the most pressing and vexing issues facing the world today. Although progress has been made in alleviating poverty in China, more efforts are needed to manage the intractable generations that have been affected by poverty. Endogenous power is the core psychological resource for low-income individuals to move out of poverty. However, there is a lack of a research framework for the endogenous power of poverty elimination in the Chinese context, which may result in a scarcity of relevant empirical research and the neglect of psychological factors in the formulation of poverty alleviation policies. This study deploys qualitative research methods to explore the psychological structure and key influencing factors of endogenous power of generations of low-income individuals with a goal of providing proposals on psychologically targeted poverty alleviation. The researchers utilized an intensity sampling method to obtain study participants, and grounded theory, based on in-depth interviews, was adopted as research methodology. Participants comprised individuals who had successfully (seven people) or unsuccessfully (ten people) pulled themselves out of poverty as well as poverty alleviation cadres (four cadres) from a deeply impoverished village on Hainan Island. This study attempts to construct an integral endogenous power depletion model for intergenerational poverty from the perspectives of endogenous power for poverty elimination and the integration of endogenous and exogenous driving forces. The study followed the standard procedure of grounded theory, and we analyzed the data with Nvivo 11.0. Based on grounded theory, preliminary analysis, generic analysis, and theoretical construction of the collected data were conducted. Inspections of the participants and non-participants were used to verify the research results’ validity. The findings of the study fall into three categories. First, the “Three-factor Onion Model” with negative values, negative self-concept, and the behavioral tendencies of passive anti-poverty as the core factors was found to be the endogenous driving force of generations of low-income individuals. Second, perceived control loss as a psychosocial driving force is an important cause of the lack of endogenous power among those poverty-stricken people for generations, and the combination of a lack of market rationality and campaign-style poverty alleviation are external causes of perceived control loss. Third, under the influence of the construction of inner capacities, parenting capabilities become an important internal driving force, as they take an intermediate role during the promotion of endogenous powers to their offspring and help cultivate positive psychological resources for the family. This paper attempts to place the internal psychological factors and external key factors that lead to generational poverty into a holistic research framework. Although some enlightening views have been obtained, the results are constrained by the complexity of the theme and the limitations of the data, and only a general exploration could be made. In the future, quantitative research methods may be adopted to verify the accuracy of the Internal Motivation Depletion Model for intergenerational poverty. "
