Tusnady's inequality revisited

Tusnady's inequality is the key ingredient in the KMT/Hungarian coupling of the empirical distribution function with a Brownian bridge. We present an elementary proof of a result that sharpens the Tusnady inequality, modulo constants. Our method uses the beta integral representation of Binomial tails, simple Taylor expansion and some novel bounds for the ratios of normal tail probabilities.Comment: Published at http://dx.doi.org/10.1214/009053604000000733 in the Annals of Statistics (http://www.imstat.org/aos/) by the Institute of Mathematical Statistics (http://www.imstat.org

Human resource management with Islamic management principles:a dialectic for a reverse diffusion in management

Purpose – The purpose of this paper is to explore the nature and contents of Islamic management practices and their consequent implications for human resource management (HRM) in Arab countries. In addition, it aims to examine the implications for multinational companies (MNCs) operating in Islamic countries and the impact of globalisation before proceeding to an analysis of managerial problems in Arab countries and the need for understanding Islamic management principles by Arab (national) and international managers. Design/methodology/approach – The paper takes the form of a qualitative approach based on an extensive review of relevant literature and the employment of examples from selected Arab countries. Findings – The study reveals that a gap exists between the theory of Islamic management and the practice of management in Arab countries. Management in Arab countries is informed and heavily influenced by non-Islamic traditional and national cultural values and norms of different countries and by Western management thinking rather than Islamic principles derived from the Holy Quran (words of God) and the Hadith (words of the Prophet Mohamed). Research limitations/implications – The paper argues that one of the main reasons for the lack of progress in most Arab and Islamic countries is the mismatch between global integration and local responsiveness because of an excess forward diffusion of Western management and business practices with little understanding and, hence, the implementation of Islamic management principles by both local and international managers in Arab countries. It adopts the view that there is a gap between the knowledge possessed by national and international managers in order to manage locally and what is required from the local workforce to be managed effectively. The main limitation of this study is the lack of empirical research evidence to support the points deducted from this review of literature. Practical implications – Understanding Islamic management principles could help to develop a more appropriate type of management best practice in Arab and Islamic countries while still benefiting from the transfer of relevant Western management techniques and Western technology. The paper also argues that a reverse diffusion of management knowledge and skills by managers of MNCs is very important for the effective management of human resources in host countries. National cultural contexts and different views of work values have made a major impact on the ability of firms to address HRM issues in different cultural settings. Originality/value – The paper contributes to the comparatively sparse literature on Islamic management and its applications by identifying key issues for HRM implementation and in developing Western understanding of Islamic management systems

Calibrating an ice sheet model using high-dimensional binary spatial data

Rapid retreat of ice in the Amundsen Sea sector of West Antarctica may cause drastic sea level rise, posing significant risks to populations in low-lying coastal regions. Calibration of computer models representing the behavior of the West Antarctic Ice Sheet is key for informative projections of future sea level rise. However, both the relevant observations and the model output are high-dimensional binary spatial data; existing computer model calibration methods are unable to handle such data. Here we present a novel calibration method for computer models whose output is in the form of binary spatial data. To mitigate the computational and inferential challenges posed by our approach, we apply a generalized principal component based dimension reduction method. To demonstrate the utility of our method, we calibrate the PSU3D-ICE model by comparing the output from a 499-member perturbed-parameter ensemble with observations from the Amundsen Sea sector of the ice sheet. Our methods help rigorously characterize the parameter uncertainty even in the presence of systematic data-model discrepancies and dependence in the errors. Our method also helps inform environmental risk analyses by contributing to improved projections of sea level rise from the ice sheets

Using the ICF and psychological models of behavior to predict mobility limitations

Aims to test the ability of a model that integrates the theory of planned behavior (TPB) into the International Classification of Functioning Disability and Health (ICF) to predict walking limitations in adults awaiting hip or knee replacement surgery. Study Design and Participants: Cross-sectional structural equation modeling study of activity limitations in 190 adults. Method: A postal questionnaire measuring the TPB, ICF and walking limitations. Results: The integrated model accounted for more variance in activity limitations (57%) than either the TPB or ICF alone. Control beliefs (TPB) significantly mediated the relationship between impairment (ICF) and activity limitations. Conclusions: The integrated model provides an interdisciplinary theoretical framework that identifies intervention targets to effect reductions in disability without the need for concomitant reductions in impairment

A partnership model for development: Australian non-government organisations and the special case of the Asia Partnership for Human Development

This thesis examines the Asia Partnership for Human Development, a comparatively new approach to the funding of the projects and programs of a set of Roman Catholic non-government aid organisations. The Partnership attempts to change the accepted pattern of relationship between the agencies in the high and low income countries so as to ensure that the decision making process is brought nearer to those undergoing the experience of development. It is an attempt to transform a \u27donor-recipient\u27 relationship into a round-table relationship where all partners have an equal say in the deployment of resources
