Leader succession often occurs because a performance decline highlights the need for change within an organization. When this need is especially high, successors are likely to be drawn from different cognitive communities than those of the replaced incumbents. Successors representing different cognitive communities carry out more change immediately after succession. This increased, rapid change will be most effective when the new leaders have had successful recent “top-job” experience. When successors lack recent top-job success, too much change too soon will actually hurt performance. We find moderate support for these relationships using panel data from the USA's National Football League.  相似文献

Schema-congruent positive autobiographical memories of past experiences with parents, a legacy of secure attachment, may operate jointly with secure attachment to predict social and personality outcomes. The current study examines the moderating role of emerging adults’ autobiographical memories of parents on the relations between maternal and paternal attachment and self-regulation, personal distress, and pathological narcissism. Undergraduates (N = 156, 66.7% female, 53.2% White, Mage = 19.3) completed a battery of measures assessing secure attachment, self-regulation, personal distress, and pathological narcissism (vulnerable and grandiose). Participants were instructed to recall brief autobiographical memories of experiences with their parental figures. Later, they were asked to name the primary emotion associated with each memory. These emotions were coded as positive, negative, or neutral in valence. For the final analysis, a positive emotion index was constructed by subtracting the number of negative memories from the number of positive memories. Regression models simultaneously examining four outcomes (self-regulation, personal distress, and vulnerable and grandiose narcissism) were examined for both female and male parental figures. Interactions between secure attachment and positive memories were only significant for maternal model outcomes. Secure attachment was positively related to self-regulation, and negatively related to personal distress and vulnerable narcissism, when more relative positive memories were recalled. Taken together, this study provides support for the continued influence of secure attachment on social and personality outcomes in emerging adulthood. Further, this influence of secure attachment appears buttressed by readily accessible positive (relative to negative) memories of female attachment figures.  相似文献

In this article we study the theoretical properties of the simultaneous multiscale change point estimator (SMUCE) in piecewise-constant signal models with dependent error processes. Empirical studies suggest that in this case the change point estimate is inconsistent, but it is not known if alternatives suggested in the literature for correlated data are consistent. We propose a modification of SMUCE scaling the basic statistic by the long run variance of the error process, which is estimated by a difference-type variance estimator calculated from local means from different blocks. For this modification we prove model consistency for physical-dependent error processes and illustrate the finite sample performance by means of a simulation study.  相似文献

The Net Ecosystem Exchange describes the net carbon dioxide flux between an ecosystem and the atmosphere and is a key quantity in climate change studies and in political negotiations. This paper provides a spatio-temporal statistical framework, which is able to infer the Net Ecosystem Exchange from remotely-sensed carbon dioxide ground concentrations together with data on the Normalized Difference Vegetation Index, the Gross Primary Production and the land cover classification. The model is based on spatial and temporal latent random effects, that act as space–time varying coefficients, which allows for a flexible modeling of the spatio-temporal auto- and cross-correlation structure. The intra- and inter-annual variations of the Net Ecosystem Exchange are evaluated and dynamic maps are provided on a nearly global grid and in intervals of 16 days.  相似文献

According to Kohlberg our moral judgment develops in an irreversible sequence of 6 stages. Starting on a level where moral problems are perceived from an egocentric point of view until an increasingly broader and more integrated perspective replaces the initially more restricted one. By using a vignette design on the background of this theory euthanasia was selected as an example to investigate to what extent arguments can morally justify a decision. In order to judge which arguments are adequate and which are less adequate cognitive competence is required. A central task of the education system is to increase this competence. Therefore it is assumed that the impact of different arguments depends above all on the level of education. All in all, the empirical analyses reported in this article do not confirm these hypotheses. In methodological respect the analyses go beyond earlier research since a recently developed multi level procedure is used. This allows an estimate of the intra-individual answer behavior of respondents and inter-individual differences between respondents simultaneously.  相似文献

Abstract

Hypogonadism or Testosterone Deficiency (TD) in adult men as defined by low levels of serum testosterone accompanied by characteristic symptoms and/or signs as detailed further on can be found in long-recognized clinical entities such as Klinefelter syndrome, Kallmann syndrome, pituitary or testicular disorders, as well as in men with idiopathic, metabolic or iatrogenic conditions that result in testosterone deficiency. These recommendations do not encompass the full range of pathologies leading to hypogonadism (testosterone deficiency), but instead focus on the clinical spectrum of hypogonadism related to metabolic and idiopathic disorders that contribute to the majority of cases that occur in adult men.  相似文献
