组织员工心理契约修复模型——心理契约违背的延伸

在组织员工心理契约违背发展模型的基础上,从心理契约的形成、契约破裂源、契约破裂和契约违背几个节点出发对心理契约的违背过程进行研究,构造出心理契约修复模型,提出心理契约的修复机制和修复机理。文章给出要提高组织心理契约的激励效能必须减少破裂源发生频次、提高组织对破裂源的敏感性、构建破裂源预警机制以及提高员工自我修复和组织修复能力的管理结论。

Worldviews,Levels of Consciousness,and the Evolution of Planning Paradigms in Protected Areas

Abstract

Protected areas (PAs) worldwide are facing increasing visitation and complexity. Mounting pressures from the private sector are intensifying the risks associated with overtourism. The increasing strategic importance of PAs for the communities and regions in which they are situated requires improved management effectiveness; yet, recent studies indicate significant and growing systemic risk. Worldview analysis can be a valuable tool for building consciousness and informing the evolution of PA planning and management. Directed content analysis was used to examine two Visitor Use Plans developed for the Coyhaique National Reserve, located in the iconic Patagonia cultural area of southern Chile. The plans were developed using distinct planning frameworks, with different underlying assumptions. Research questions focused on how modernist, postmodernist and integral worldviews were expressed within the two plans. Worldviews were explored in both manifest and latent manners, considering plan text, models and overall context revealing patterns and links between the plans and planning frameworks that guided their development. Rich context and a thorough discussion of methods assists with the incorporation of worldview evaluation within PA management theory, informing the continuing development of knowledge and capacities that can better prepare PAs for future challenges.

Varying Coefficient Regression Models: A Review and New Developments

Varying coefficient regression models are known to be very useful tools for analysing the relation between a response and a group of covariates. Their structure and interpretability are similar to those for the traditional linear regression model, but they are more flexible because of the infinite dimensionality of the corresponding parameter spaces. The aims of this paper are to give an overview on the existing methodological and theoretical developments for varying coefficient models and to discuss their extensions with some new developments. The new developments enable us to use different amount of smoothing for estimating different component functions in the models. They are for a flexible form of varying coefficient models that requires smoothing across different covariates' spaces and are based on the smooth backfitting technique that is admitted as a powerful technique for fitting structural regression models and is also known to free us from the curse of dimensionality.

This article examines the notion of distortion of copulas, a natural extension of distortion within the univariate framework. We study three approaches to this extension: (1) distortion of the margins alone while keeping the original copula structure; (2) distortion of the margins while simultaneously altering the copula structure; and (3) synchronized distortion of the copula and its margins. When applying distortion within the multivariate framework, it is important to preserve the properties of a copula function. For the first two approaches, this is a rather straightforward result; however, for the third approach, the proof has been exquisitely constructed in Morillas (2005). These three approaches unify the different types of multivariate distortion that have scarcely scattered in the literature. Our contribution in this paper is to further consider this unifying framework: we give numerous examples to illustrate and we examine their properties particularly with some aspects of ordering multivariate risks. The extension of multivariate distortion can be practically implemented in risk management where there is a need to perform aggregation and attribution of portfolios of correlated risks. Furthermore, ancillary to the results discussed in this article, we are able to generalize the formula developed by Genest &; Rivest (2001) for computing the distribution of the probability integral transformation of a random vector and extend it to the case within the distortion framework. For purposes of illustration, we applied the distortion concept to value excess of loss reinsurance for an insurance policy where the loss amount could vary by type of loss.
