this comment is to show that theorem3.3 of dey and chung (1991) (multiparameter estimation intruncated power series distributions under the stein's loss.emph{commun. statist.-theory meth.,} {bf 20}, 309-326) may giveus misleading results. analytically and through simulation, weshow that the theorem does not improve the given estimator.

Identical Starting-Points. A consequence of the globalization of our lives is also manifest in the similarities in the discussion about the phenomenon "information society" in such countries as Thailand and Germany, which are so far apart in distance, history and culture. At first glance, the subject-matter, structure and rhetoric of this discussion are the same here as there. The main concern ...

This comment on Professor Fotaki’s Editorial agrees with her arguments that training health professionals in more compassionate, caring and ethically sound care will have little value unless the system in which they work changes. It argues that for system change to occur, senior management, government members and civil servants themselves need training so that they learn to understand the effec...

Successful prevention and control of the epidemic of noncommunicable diseases (NCDs) cannot be achieved by the health sector alone: a wide range of organisations from multiple sectors and across government must also be involved. This requires a new, inclusive approach to advocacy and to coordinating, convening and catalysing action across civil society, best achieved by a broad-based network. T...

Sweden and Spain experiment with different provider models to reform healthcare provision. Both models have in common that they extend the role of the for-profit sector in healthcare. As the analysis of Saltman and Duran demonstrates, privatisation is an ambiguous and contested strategy that is used for quite different purposes. In our comment, we emphasize that their analysis leaves questions ...

Prospective studies of the potential health consequences of trade and investment treaties, such as the Trans-Pacific Partnership, are critical. These studies can make visible to trade policy-makers the potential negative impacts associated to such treaties and can influence the outcomes of such negotiations. However, few researchers have examined retrospectively the consequences of trade agreem...

In his perspective “Navigating between stealth advocacy and unconscious dogmatism: the challenge of researching the norms, politics and power of global health,” Ooms argues that actions taken in the field of global health are dependent not only on available resources, but on the normative premise that guides how these resources are spent. This comment sets out how the application of a predomina...

A mathematical model has been introduced for the transmission dynamics of cholera disease by GQ Sun et al. recently. In this study, we add Laplacian and Triangular random effects to this model and analyze the variation of results for both cases. The expectations  and coefficients of variation are compared for the random models and the results are used to comment on the differences and similarit...
