This article examines some difficulties associated with the Haynes–Stone model and attempts to clarify how the model can be justified as representing the hypothesis that “quantity is demand determined and price is supply determined.” It also argues that the applications of such a model as was done by Haynes and Stone might not have resolved the controversies related to the Phillips curve and the supply function of exports (or imports).     

The Detection of Influential Observations for Allocation,Separation, and the Determination of Probabilities in a Bayesian Framework

Normal theory separation and allocation problems are discussed from a predictive point of view. Influence statistics are defined and employed to ascertain the impact that particular observations will have on the inferential goals—allocation of future observations, separation between populations, and the determination of probabilities for future cases. Methods are illustrated on a collection of financial data taken from Johnson and Wichern (1982).     

Reviews

Abstract

The chronological entries in Weblogs or blogs record musings, opinions, news or other information supplied by individuals or groups. The nature of blogs is ephemeral in that the content is closely tied to the time period of the posting. The author examines the library and information science blogs listed on Susan Herzog’s “BlogBib: Select Librarian/Library Blogs” to see if they were being updated thirteen months after Herzog stopped maintaining the Web site.¹ Active, inactive, ceased, and blogs with changed URLs were recorded. Extra content was noted.     

Perspectives on Job Stress in the Serials Information World

Abstract

Adam Chesler describes his experiences and observations of job stress in the serials publishing industry. While stresses, such as the challenges of supervision have always existed, others are new, such as serial publishers scrambling to adapt service and pricing models for providing Internet content. Advice is offered on coping with these stresses.

Tables to Facilitate Fitting Tadikamalla and Johnson's LB Distributions

This paper is concerned with estimating the parameters of Tadikamalla-Johnson's L_B distribution using the first four moments. Tables of the parameters of the L_B distribution are given for selected values of skewness (0.0(0.05) 1.0(0.1)2.0) and corresponding available values of kurtosis at intervals of 0.2. The construction and use of these tables is explained with a numerical example.     

Errors in inspection and grading distributional aspects ofscreening and merarchal screening

Continuing the studies of Johnson et al (1980) and Johnson and Kotz (1981), further distributions arising from models of errors in inspection and grading of samples from finite, possibly stratified lots are obtained. Screening, and hierarchal screening forms of inspection are also considered, and the effects of errors on the advantages of these techniques assessed.
