Attachment and leader's development via experiences

Apart from biographies and memoirs of outstanding leaders, studies on the development of leaders in everyday life from childhood to maturity are rare. We propose a developmental model of leaders in which certain variables formed in early childhood are the basic components for leadership development in later life. These are a low level of trait anxiety [Spielberger, C.D. (1972). Conceptual and methodological issues in anxiety research. In C.D. Spielberger (Ed.), Anxiety: Current trends in theory and research. New York: Academic Press, vol. 1] and openness to experiences [Costa, P.T. Jr., & McCrae, R.R. (1992a). Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) professional manual. Odessa, FL: Psychological Assessment Resources]. We argue that secure attachment style [Bowlby, J. (1969). Attachment and loss: Vol. 1. Attachment. New York: Basic Books] explains the formation and influence of these basic components, which in turn affect the leader's development through experience in leadership roles. Questionnaires were administered to 286 subjects. The data obtained were analyzed by structural equation modeling (SEM).The findings show that trait anxiety and openness to experience affect leaders' development via experiences. Alternative models in which formative variables may affect the magnitude and intensity of leadership experiences are discussed.     

多人从经验中学习模型研究：基于信息和分析方法不对称视角

当前,日益复杂且动态变化的形势和环境对多人从过往事件中不断学习、积累应对经验、快速迭代应对措施等提出了更高的要求。然而,在多人从经验中学习时,常出现由于不同个体间不了解彼此掌握的信息和会使用的分析方法而导致的莫衷一是、讨论进程拖沓、无法及时达成结论等现象。本文将个体间不了解彼此掌握的信息和/或会使用的分析方法的现象概括为“不对称”,并采用理论构建的方法,聚焦于多人从经验中学习的过程,以“信息”和“分析方法”为维度,构建基于信息不对称性和分析方法不对称性的二维矩阵,提出多人从经验中学习时会存在信息不对称且分析方法不对称、信息不对称且分析方法对称、信息对称且分析方法不对称,以及信息对称且分析方法对称四种情况,并指出信息和/或分析方法的不对称性会降低多人从经验中学习的效率,构建了基于不对称性视角的多人从经验中学习过程机制模型。随后,从“意愿”和“能力”两个方面,提出了降低信息和分析方法不对称性的实践方法,建立了降低不对称性的多人从经验中学习的实践方法库。本文针对多人从经验中学习时,由于信息和/或分析方法的不对称性而导致的问题进行探索,并为提升学习效率提供了理论基础和实践指导。     

管理者过度自信与企业投资行为异化——来自我国证券市场的经验证据

本文以非金融类A股上市公司为研究样本,考察了管理者过度自信与企业投资行为的关系。研究发现,过度自信的管理者倾向于过度投资,并对融资活动产生的现金流有更高的敏感性。即当公司有充裕的融资活动现金流时,过度自信的管理者会过度投资;反之,则投资不足。本文还发现,过度投资与经营活动产生的自由现金流之间的敏感性基本上不受管理者过度自信心理特征的影响,这与其它一些研究的结论不一致。

Little naked pangs of the self: the real performance of the self and the function of trust in Goffman's action theory

The aim of this article is to discuss some of the leading features of Erving Goffman's action theory as an alternative to the ‘orthodox’ paradigms of sociology, viewed as a structuralist and functionalist science that defines social constructs by their shared rules and values, and as a drifting of action, in the sense of intention, toward an individualistic version. The author examines Goffman's shift of the focus of attention from the boundaries of a social sense of action to the social dialectic of ‘defining a situation’ (W. Thomas) as conducted by the social actors in a renewal of Simmel's ‘empowering covenants’ (wechselwirkung) in the multiple casual social connections that make up the ‘social buzz’ in a society. The author moreover discusses Goffman's action as a kind of playacting regulating cognitive and expressive face-to-face ‘traffic’ between the social actors. This relational dynamic creates an interactive play based on encounters – in which one's opening to another is fraught with risks of deception – regulated by trust as a central resource for social interactions. Trust, in its interpersonal and systemic variants, constitutes a universal social datum and an elementary precondition for social exchanges and the cooperation between individuals. Trust, thus, functions as comparer between reciprocal expectations and a regulator of freedom tending to the stability of the social system.     

Approach to normality of mean and M-estimators of location

The approach to normality of an estimate is displayed graphically by the nonlinearity in the derivative of the log density, and this nonlinearity is related to the accuracy of the normal approximation for the tail area. Using techniques from small-sample asymptotics, an alternate proof of the central limit theorem is given and same indices of tail behavior are examined.

也谈明清时期大陆移民渡台的原因与类型

明清时期闽粤沿海地区的民众之所以源源不断地渡海入台，除了受自然灾害、战乱频繁、人稠地狭、欺骗性谣言、垦户招佃等社会政治经济因素的影响外．移民勇于冒险打拼的人文性格也起了不容忽视的作用。按照渡台的最初动机，大陆移民主要有两种类型，一为追求生存型移民，二为投资营利型移民。
