SIO Reference 59-65. This report describes a theoretical analysis of the detection and recognition capability of an ideal mosaic detector. The relationship between detection and recognition for this idealized mosaic is used to hypothesize a criterion for the threshold of visual recognition. A brief psychophysics experiment was performed as a first test of this hypothesis. The degree of success and the limitations of the test are discussed.

SIO Reference 60-49. The Visibility Laboratory has for a number of years carried on a program of investigation of the possible application of visible spectrum photoelectric systems to problems of search and detection. On the basis of this experience, this laboratory was requested by the Navy to carry out a short term study of the feasibility of anti-collision instrumentation utilizing photoelectric apparatus operating in the visible spectrum. This report contains the results of this brief study program.

SIO Reference 58-68. The purpose of this note is to introduce the concept of the contrast transmittance distribution and to point out its potentially useful application to the general visibility problems in natural aerosols and hydrosols.

SIO Reference 60-45. The function of a photoelectric system should be to improve upon the performance capabilities of unaided visual search. This report will therefore start with a very brief analysis of the visual detection capability. Succeeding sections of the report will discuss each parameter of the search geometry and indicate, where possible, modification of the parameter which will lead to improved performance. The final sections will describe a photoelectric system capable of incorporating the improvements indicated in the paragraphs which precede it and capable of day and night operation at a performance level surpassing the specified Navy requirements.

Clinical nurse leader (CNL)-integrated care delivery is an emerging nursing model, with growing adoption in diverse health systems. To generate a robust evidence base for this promising nursing model, it is necessary to measure CNL practice to explicitly link it to observed quality and safety outcome improvements. This study used a modified Delphi approach with an expert CNL panel to develop and test the face, content, and construct validity of the CNL Practice Survey instrument.
