Organizational Sustainability and Systemic Boundary Processes

Abstract

Every day, managers work to sustain the organizations wherein they work. In this article, the authors examine certain systemic boundary processes that are intrinsic to organizations and their sustainability. For readers of this journal, whose name points to the inherent connection between organizations and society, the authors present an argument that organizational boundary processes and their influence on organizational sustainability are important considerations for those of us interested in a viable future for our society. The importance of these processes for managers also is indicated.     

Personalisation,individualism and the politics of disablement

This paper assesses the social policy narrative personalisation, and particularly the implications of the narrative for disability politics. The advantages and disadvantages of positioning specific funding mechanisms within the narrative are explored. It is argued that personalisation is insufficiently aligned with collective aspects of empowerment. More particularly, it disproportionately emphasises improvements in individual autonomy through personalised support, and lacks reference to structural oppression or the need for collective forms of action that bring about structural change. It is further argued that personalisation lack a multi-faceted analysis of disability and disempowerment, and as a result also lacks any vision of a positive alternative society. In assessing personalisation, the positive and negative dimensions of disabled people’s freedom are considered. As a response to the apparent shortcomings of personalisation, the integrated living approach and Centres for Independent Living are considered important elements in an alternative narrative to personalisation.     

Ageing Society Issues in Korea*

Korean society is facing unprecedentedly higher population ageing, particularly in the first half of the 21st century. The implications of population ageing have a much wider effect than the welfare of the elderly. From a broader and long‐term perspective, understanding population ageing may require a new paradigm. Korea has attempted to model its policies for ageing society on those of advanced welfare states, but as these no longer seem viable, Korean policy‐makers are searching for more effective and efficient measures to deal with its rapid ageing population. Reflecting a broader and long‐term perspective, the Korean government recently produced a comprehensive national policy plan to deal with the consequences of rapid population ageing. This article outlines the phenomenon of population ageing in Korea and the recent development of national policies for population ageing, describing the Korean comprehensive national policy plan for responding to it and examining major issues and problems related to developing and implementing the plan. This article finally suggests a new, age‐integrated social system approach to an ageing society.     

三螺旋混成组织视阈下的科学知识生产

多价知识观的提出改变了传统的强调科学知识生产过程特定要素或某个片段的视阈,内在地要求以集成性的观点来审视科学组织。在分析知识多价性与科学知识生产场域集成性关系的基础上,阐释了大学—产业—政府三螺旋混成组织是一种科学知识生产的集成性组织。它捕捉了科学知识生产过程中包含学术、市场和政策的多元重叠关系,使科学知识生产所需的资源、组织结构及运作过程都具有集成性特征。     

Bayesian autoregressive spectral analysis

The article describes an operational Bayesian approach to making inferences for the spectral density function for univariate autoregressive processes and for the AR operator of multivariate autoregressive processes. The derivation of the approach is described. Numerical examples, including the Wolfer Sunspot numbers, are used to demonstrate the practical usefulness of the approach.     

ARFIMA processes and outliers: a weighted likelihood approach

In this paper, we consider the problem of robust estimation of the fractional parameter, d, in long memory autoregressive fractionally integrated moving average processes, when two types of outliers, i.e. additive and innovation, are taken into account without knowing their number, position or intensity. The proposed method is a weighted likelihood estimation (WLE) approach for which needed definitions and algorithm are given. By an extensive Monte Carlo simulation study, we compare the performance of the WLE method with the performance of both the approximated maximum likelihood estimation (MLE) and the robust M-estimator proposed by Beran (Statistics for Long-Memory Processes, Chapman & Hall, London, 1994). We find that robustness against the two types of considered outliers can be achieved without loss of efficiency. Moreover, as a byproduct of the procedure, we can classify the suspicious observations in different kinds of outliers. Finally, we apply the proposed methodology to the Nile River annual minima time series.     

HAZARD RATE ESTIMATION FOR CENSORED DATA BY WAVELET METHODS

ABSTRACT

We study the estimation of a hazard rate function based on censored data by non-linear wavelet method. We provide an asymptotic formula for the mean integrated squared error (MISE) of nonlinear wavelet-based hazard rate estimators under randomly censored data. We show this MISE formula, when the underlying hazard rate function and censoring distribution function are only piecewise smooth, has the same expansion as analogous kernel estimators, a feature not available for the kernel estimators. In addition, we establish an asymptotic normality of the nonlinear wavelet estimator.     

Sums of weighted spacings and a test for the logistic distribution

A simple proof for a theorem of Csörgö and Révész (1981b and 1984) concerning sums of weighted spacings is given, The conditions of the theorem are relaxed. As an application, a goodness-of-fit test for the logistic distribution is proposed. The percentage points of the proposed test statistic are obtained by a simulation experiment.
