作为解构主义美学的核心观念.解构指向的是一种本体性的、生生不息的、蕴含着极大颠覆性与创造性的内驱力。解构产生于结构成为结构的那一刻,是对他者性召唤的肯定性应答,是对结构等级制秩序的颠覆。解构在解放他者的同时也解放了他者的对立面,它不知疲倦地从一种结构奔向另一种全新的结构,以致无穷。解构性事件就是这从一个结构转向另一个结构的关节点。解构特有的自由、民主精神使得解构主义美学成为一种批判的理论、一种肯定的理论,同时它还是一种辩证法。  相似文献

通过对锡林郭勒盟退化草场放牧实验区内不同放牧强度下,1993~1996年土壤微生物数量变化及综合治理试验区的土壤微生物数量变化的初步研究得出:在退化草场中采取围栏封育或适度放牧,可以提高土壤肥力和微生物数量,对退化草场的恢复演替有良好的促进作用。  相似文献

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized techniques. We consider both linear and nonlinear models where the regression coefficients are heterogeneous across groups but homogeneous within a group and the group membership is unknown. Two approaches are considered—penalized profile likelihood (PPL) estimation for the general nonlinear models without endogenous regressors, and penalized GMM (PGMM) estimation for linear models with endogeneity. In both cases, we develop a new variant of Lasso called classifier‐Lasso (C‐Lasso) that serves to shrink individual coefficients to the unknown group‐specific coefficients. C‐Lasso achieves simultaneous classification and consistent estimation in a single step and the classification exhibits the desirable property of uniform consistency. For PPL estimation, C‐Lasso also achieves the oracle property so that group‐specific parameter estimators are asymptotically equivalent to infeasible estimators that use individual group identity information. For PGMM estimation, the oracle property of C‐Lasso is preserved in some special cases. Simulations demonstrate good finite‐sample performance of the approach in both classification and estimation. Empirical applications to both linear and nonlinear models are presented.  相似文献

Increasing levels of displacement and the need to integrate refugees in the workforce pose new challenges to organizations and societies. Extant research on refugee employment and workforce integration currently resides across various disconnected disciplines, posing a significant challenge for management scholars to contribute to timely and relevant solutions. In this paper, we endeavour to address this challenge by reviewing and synthesizing multidisciplinary literature on refugee employment and workforce integration. Using a relational framework, we organize our findings around three levels of analysis – institutional, organizational and individual – to outline the complexity of factors affecting refugees’ employment outcomes. Based on our analysis, we introduce and elaborate on the phenomenon of the canvas ceiling ? a systemic, multilevel barrier to refugee workforce integration and professional advancement. The primary contributions of this paper are twofold. First, we map and integrate the multidisciplinary findings on the challenges of refugee workforce integration. Second, we provide management scholarship with a future research agenda to address the knowledge gap identified in this review and advance practical developments in this domain.  相似文献

Increasing interest in participatory budgeting has been observed in local governments around the world. This paper stresses direct citizen participation in the budgeting process leads to good governance, deepens democracy and improves social justice, while also highlighting some challenges in its efficiency and effectiveness. Unlike participatory budgeting, the Sub-borough Chiefs Forum is a community-based representative democratic mechanism; it could be regarded as a form of participatory budgeting in a broad sense. If so, then did the Taipei programme simply duplicate the goals of the Forum or lead to a better governance by making up for the inadequacies of the Chiefs Forum? To find out whether the Taipei participatory budgeting programme made a difference, we carried out qualitative and quantitative comparisons of projects passed under the participatory budgeting process and at the Forum. We also interviewed several participatory budgeting participants and sub-borough chiefs. The findings suggested that participatory budgeting and the Forum generated different proposals and budget requests, and the Taipei programme supplemented the shortcomings of the Forum and therefore led to deeper civic engagement and better urban governance.  相似文献

The ongoing project of citizenship construction in societies receiving international immigration demands a perspective that takes into account the interests, views and needs of all socio-demographic groups, including those of newcomers as potential new citizens. We interviewed representatives of 16 immigrant associations operating in the Spanish autonomous community of Galicia, reviewed immigration policy in 13 Spanish (Galician) municipalities, and interviewed 20 municipal government staff members who put these into practice. With this research, we aim to explore the perspectives of immigrants with respect to their own integration and to examine how these compare with local policies designed to facilitate these processes. By comparing the immigrant representatives' perceptions with local policy discourses and practice, our study reveals how local integration practice is not only inconsistent with its own policy discourse but also fails to consider and include immigrants' own understandings of what integration means and how it can be achieved.  相似文献
