Moment expressions and summary statistics for the complete and truncated weibull distribution

Traditionally, the moments of the Weibull distribution have been calculated using the standard Weibull (Johnson and Kotz, 1970) . This article will expand on that idea and cover the truncated cases for the standard Weibull distributions. Also, the same techniques used for the standard form will be used to derive the moment expressions for the three-parameter complete and truncated Weibull distributions. The summary statistics are then calculated from the moment expressions. Weibull moments involve the gamma and incomplete gamma functions.     

State versus Market: Contending Interests in the Struggle to Control French Accounting Standardisation

The paper concerns the struggle between different interest groups to control or significantly influence the objectives, institutional arrangements and processes of French accounting standardisation. Its particular focus of interest is the state agency established to deal with standardisation, namely the National Accounting Council, the Conseil National de la Comptabilité (CNC), and its predecessors. The period addressed spans from 1941 to the present, marked by the first attempt to implement a national accounting code, adoption of the initial post-war code in 1947 and subsequent revisions.The paper identifies and examines the role played by the French state in establishing an institutional structure for accounting standardisation and in seeking to influence operation of that structure as a means to achieve a concertation of diverse social and economic interest groups with an interest in accounting standards. The objective for the process from the viewpoint of the state has been seen as the intended dominance of certain interests of state over other interests, whether public sector or otherwise. In the course of time, the dominant interests of the state have changed in the face of changing expectations about the role of financial accounting and reporting in the financial life of France. The role of the state is seen to have come under increasing pressure from private sector interests in France and externally. Particular attention is given to the 1996–8 major reforms to the CNC and associated new regulatory structure.The possibility is assessed of whether and under what terms the French approach to accounting standardisation can be sustained, grounded as it is in a profound attachment by the state to the values of the Etat colbertiste.     

Metapreferences and the reasons for stability in social choice: Thoughts on broadening and clarifying the debate

The standard model of collective choice looks at aggregation procedures which take individual preferences as existing for a specified set of alternatives. In this paper we propose that actors also have preferences for rules of choice or characteristics of choice processes (e.g., the perceived fairness of procedures or the popularity of outcomes) rather than simply for alternatives (outcomes) themselves. We argue that the positing of the existence of meta-preferences can illuminate a number of areas of choice theory. Here we focus on one such area: the problem of “too much” stability in majority rule decision making - a stability which belies the standard theoretical results on the generic instability of majority rule processes. We also show that discussion of the prevalence of stability in collective decision making needs to be clarified because there are at least six distinct types of stability which are sometimes confounded in the literature.     

The Social Sharing of Emotion as an Interface Between Individual and Collective Processes in the Construction of Emotional Climates

The study of private emotional experiences reveals that an emotion is typically followed by social sharing. Additionally, the target's responses stimulate the sharing person's emotional expression. The reciprocal stimulation of interactants favors empathy and emotional communion. Consequences are two-fold: (1) the sharing process reactivates emotional arousal in both agent and target, and (2) it strengthens social bonds. Sharing targets also share what they heard with others, who then experience a similar need. Social sharing also develops when an emotional event strikes collectively. In this case, however, the propagation consequences are geared up in a spectacular manner both because there are as many sharing sources as there are members in the community and because every sharing reactivates felt emotions among interactants, thus reloading the propagation flow. It is argued that such chain reactions contribute to construct an emotional climate in the concerned community. It is predicted that emotion sharing would impact (1) on emotional climate in general; (2) on group cohesion and solidarity, with positive consequences for emotional climate; and (3) on collective memory, with potential consequences for emotional climate in the long run. Each of these predictions is detailed and illustrated with available empirical evidence.     

How Dangerous Is Low Level Radiation?

Problems in the theoretical basis for the linear-no threshold theory of radiation carcinogenesis are reviewed, and it is shown that they very strongly suggest that the theory greatly overestimates the risk of low level radiation. A direct test of the theory, based on the radon—lung cancer relationship is described; it strongly reinforces that conclusion. However, it is shown that even if the linear-no threshold theory is valid, the public's fear of low level radiation, at least in some contexts, is grossly exaggerated.     

A simplified taxonomy of 2 × 2 games

All 2 × 2 games are classified into eight configurations, following three natural criteria, and prototypes given for each, especially as concerns the Newcomb and chain-store paradoxes. Two pseudo-dynamic properties, move priority and dynamic inconsistency, are examined in that framework, as well as more specifically, the problem of the origin of social institutions.     

Estimation bayesienne des effets dans le modele a effets aleatoires de classification double avec interaction

The problem of estimating the effects in a balanced two-way classification with interaction \documentclass{article}\pagestyle{empty}\begin{document}$i = 1, \ldots ,I;j = 1, \ldots ,J;k = 1, \ldots ,K$\end{document} using a random effect model is considered from a Bayesian view point. Posterior distributions of r_i, c_j and t_ij are obtained under the assumptions that r_i, c_j, t_ij and e_ijk are all independently drawn from normal distributions with zero meansand variances \documentclass{article}\pagestyle{empty}\begin{document}$\sigma _r^2 ,\sigma _c^2 ,\sigma _t^2 ,\sigma _e^2$\end{document} respectively. A non informative reference prior is adopted for \documentclass{article}\pagestyle{empty}\begin{document}$\mu ,\sigma _r^2 ,\sigma _c^2 ,\sigma _t^2 ,\sigma _e^2$\end{document}. Various features of thisposterior distribution are obtained. The same features of the psoterior distribution for a fixed effect model are also obtained. A numerical example is given.     

Probabilistic Risk Analysis for a High-Level Radioactive Waste Repository

A probabilistic risk analysis (PRA) for a high-level radioactive waste repository is very important since it gives an estimate of its health impacts, allowing comparisons to be made with the health impacts of competing technologies. However, it is extremely difficult to develop a credible PRA for a specific repository site because of large uncertainties in future climate, hydrology, geological processes, etc. At best, such a PRA would not be understandable to the public. An alternative proposed here is to develop a PRA for an average U.S. site, taking all properties of the site to be the U.S. average. The results are equivalent to the average results for numerous randomly selected sites. Such a PRA is presented here; it is easy to understand, and it is not susceptible to substantial uncertainty. Applying the results to a specific repository site then requires only a simple, intuitively acceptable "leap of faith" in assuming that with large expenditures of effort and money, experts can select a site that would be at least as secure as a randomly selected site.
