Recognition as a Measure of Learning from Television Commercials.
This is the published version. Copyright 1983 American Marketing Association.Recognition has not received extensive acceptance by practitioners as a response variable for learning of television commercials. The authors review some of the distinctions between recoil and recognition, and some of the problems associated with each. In a laboratory experiment they developed and tested a measure of recognition useful for low involvement situations in which a recall level of learning may not be necessary. Data and implications about the usefulness and limitations of the measure are presented
Recognition versus recall as measures of television commercial forgetting.
This is the published version. Copyright 1993 by the American Marketing Association.Investigated the impact of time since exposure, commercial length, and commercial repetition on recognition and unaided recall scores, using 204 undergraduates. Ss were randomly assigned to 12 experimental cells and asked to recall the product category, brand name, and claims for commercials they viewed; similarly 9-alternative verbal recognition tests were used. Results indicate that recognition scores were not indiscriminately high, as commonly is argued and that they declined with time, contrary to what often is assumed. The data show that recognition scores were more sensitive and more discriminating than, and covaried with, unaided recall scores. It is suggested that recognition and recall warrant more consideration by advertisers. Findings are compared to an earlier study by the 1st 2 authors (see record 1984-05496-001).

Testing Human Sperm Chemotaxis: How to Detect Biased Motion in Population Assays
Biased motion of motile cells in a concentration gradient of a chemoattractant is frequently studied on the population level. This approach has been particularly employed in human sperm chemotactic assays, where the fraction of responsive cells is low and detection of biased motion depends on subtle differences. In these assays, statistical measures such as population odds ratios of swimming directions can be employed to infer chemotactic performance. Here, we report on an improved method to assess statistical significance of experimentally determined odds ratios and discuss the strong impact of data correlations that arise from the directional persistence of sperm swimming
Six Years of Chandra Observations of Supernova Remnants
We present a review of the first six years of Chandra X-ray Observatory
observations of supernova remnants. From the official "first-light" observation
of Cassiopeia A that revealed for the first time the compact remnant of the
explosion, to the recent million-second spectrally-resolved observation that
revealed new details of the stellar composition and dynamics of the original
explosion, Chandra observations have provided new insights into the supernova
phenomenon. We present an admittedly biased overview of six years of these
observations, highlighting new discoveries made possible by Chandra's unique
capabilities.Comment: 82 pages, 28 figures, for the book Astrophysics Update
Precision medicine in cats:novel niemann-pick type C1 diagnosed by whole-genome sequencing
State-of-the-art health care includes genome sequencing of the patient to identify genetic variants that contribute to either the cause of their malady or variants that can be targeted to improve treatment. The goal was to introduce state-of-the-art health care to cats using genomics and a precision medicine approach. To test the feasibility of a precision medicine approach in domestic cats, a single cat that presented to the University of Missouri, Veterinary Health Center with an undiagnosed neurologic disease was whole-genome sequenced. The DNA variants from the cat were compared to the DNA variant database produced by the 99 Lives Cat Genome Sequencing Consortium. Approximately 25× genomic coverage was produced for the cat. A predicted p.H441P missense mutation was identified in NPC1, the gene causing Niemann-Pick type C1 on cat chromosome D3.47456793 caused by an adenine-to-cytosine transversion, c.1322A>C. The cat was homozygous for the variant. The variant was not identified in any other 73 domestic and 9 wild felids in the sequence database or 190 additionally genotyped cats of various breeds. The successful effort suggested precision medicine is feasible for cats and other undiagnosed cats may benefit from a genomic analysis approach. The 99 Lives DNA variant database was sufficient but would benefit from additional cat sequences. Other cats with the mutation may be identified and could be introduced as a new biomedical model for NPC1. A genetic test could eliminate the disease variant from the population
International Conference on Advances in Radiation Oncology (ICARO): Outcomes of an IAEA Meeting
The IAEA held the International Conference on Advances in Radiation Oncology (ICARO) in Vienna on 27-29 April 2009. The Conference dealt with the issues and requirements posed by the transition from conventional radiotherapy to advanced modern technologies, including staffing, training, treatment planning and delivery, quality assurance (QA) and the optimal use of available resources. The current role of advanced technologies (defined as 3-dimensional and/or image guided treatment with photons or particles) in current clinical practice and future scenarios were discussed
[Avian cytogenetics goes functional] Third report on chicken genes and chromosomes 2015
High-density gridded libraries of large-insert clones using bacterial artificial chromosome (BAC) and other vectors are essential tools for genetic and genomic research in chicken and other avian species... Taken together, these studies demonstrate that applications of large-insert clones and BAC libraries derived from birds are, and will continue to be, effective tools to aid high-throughput and state-of-the-art genomic efforts and the important biological insight that arises from them
