Scientific Uncertainty in Media Content: Some Reflections on This Special Issue

It was an honor to be called upon to be the anchor reviewer for this special issue of Public Understanding of Science devoted to new perspectives on media presentations of scientific uncertainty. But more than that, it was for me a pleasure and an education. It is always rewarding when, as one of the reviewers of submitted manuscripts, you get so engaged by the content and quality of the research in the articles before you that you have to remind yourself that your task is that of the critic. That happened repeatedly with all of the research articles in this issue. Rather than summarize each of the articles, which Peters and Dunwoody (2016) have done so well in their introduction, and rather than repeat all the valuable roadmaps for further research already contained in the articles, please allow me to share a handful of sometimes oblique observations inspired, directly or indirectly, by all of the articles in this special issue. The following reflections may refer to some articles more than others, but that should not signal any differences in the high-quality and valuable contributions of each

A review of ride comfort studies in the United Kingdom

United Kingdom research which is relevant to the assessment of vehicle ride comfort was reviewed. The findings reported in approximately 80 research papers are outlined, and an index to the areas of application of these studies is provided. The data obtained by different research groups are compared, and it is concluded that, while there are some areas of general agreement, the findings obtained from previous United Kingdom research are insufficient to define a general purpose ride comfort evaluation procedure. The degree to which United Kingdom research supports the vibration evaluation procedure defined in the current International Standard on the evaluation of human exposure to whole-body vibration is discussed

Slide rule-type color chart predicts reproduced photo tones

Slide rule-type color chart determines the final reproduced gray tones in the production of briefing charts that are photographed in black and white. The chart shows both the color by drafting paint manufacturers name and mixture number, and the gray tone resulting from black and white photographic reproduction

Bladed disk vibration

The objective was to better understand the vibratory response of bladed disk assemblies that occur in jet engines or turbopumps. Two basic problems were investigated: how friction affects flutter; and how friction, mistuning, and stage aerodynamics affect resonance. Understanding these phenomena allows a better understanding of why some stages have high vibratory stresses, how best to manage those stresses, and what to do about reducing them if they are too large
