Passing crisis and emergency risk communications: the effects of communication channel, information type, and repetition.
Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed
Evaluating the application of research-based guidance to the design of an emergency preparedness leaflet
UNLABELLED: Guidelines for the design of emergency communications were derived from primary research and interrogation of the literature. The guidelines were used to re-design a nuclear emergency preparedness leaflet routinely distributed to households in the local area. Pre-test measures of memory for, and self-reported understanding of, nuclear safety information were collected. The findings revealed high levels of non-receipt of the leaflet, and among those who did receive it, memory for safety advice was poor. Subjective evaluations of the trial leaflet suggested that it was preferred and judged easier to understand than the original. Objective measures of memory for the two leaflets were also recorded, once after the study period, and again one week or four weeks later. Memory for the advice was better, at all time periods, when participants studied the trial leaflet. The findings showcase evaluation of emergency preparedness literature and suggest that extant research findings can be applied to the design of communications to improve memory and understandability. STATEMENT OF RELEVANCE: Studies are described that showcase the use of research-based guidelines to design emergency communications and provide both subjective and objective data to support designing emergency communications in this way. In addition, the research evaluates the effectiveness of emergency preparedness leaflets that are routinely distributed to households. This work is of relevance to academics interested in risk communication and to practitioners involved in civil protection and emergency preparedness
A Study in Archival Collecting from Extremist Groups: An Investigation of Ku Klux Klan Holdings in the United States.
This study examines the quantity and placement of Ku Klux Klan materials among archival collections in five academic libraries in the United States. I discuss the importance of collecting materials from hate groups in the United States, with the Ku Klux Klan as an example, and explore challenges in outreach and description. A comparison and analysis of Ku Klux Klan holdings in repositories reveals the current status of those materials and provides insight into how repositories and archivists confront controversial research topics
The hybrid experimental simplex algorithm â An alternative method for âsweet spotâ identification in early bioprocess development: Case studies in ion exchange chromatography
The capacity to locate efficiently a subset of experimental conditions necessary for the identification of an operating envelope is a key objective in many studies. We have shown previously how this can be performed by using the simplex algorithm and this paper now extends the approach by augmenting the established simplex method to form a novel hybrid experimental simplex algorithm (HESA) for identifying âsweet spotsâ during scouting development studies. The paper describes the new algorithm and illustrates its use in two bioprocessing case studies conducted in a 96-well filter plate format. The first investigates the effect of pH and salt concentration on the binding of green fluorescent protein, isolated from Escherichia coli homogenate, to a weak anion exchange resin and the second examines the impact of salt concentration, pH and initial feed concentration upon the binding capacities of a FAbâ˛, isolated from E. coli lysate, to a strong cation exchange resin. Compared with the established algorithm, HESA was better at delivering valuable information regarding the size, shape and location of operating âsweet spotsâ that could then be further investigated and optimized with follow up studies. To test how favorably these features of HESA compared with conventional DoE (design of experiments) methods, HESA results were also compared with approaches including response surface modeling experimental designs. The results show that HESA can return âsweet spotsâ that are equivalently or better defined than those obtained from DoE approaches. At the same time the deployment of HESA to identify bioprocess-relevant operating boundaries was accompanied by comparable experimental costs to those of DoE methods. HESA is therefore a viable and valuable alternative route for identifying âsweet spotsâ during scouting studies in bioprocess development
Redefining the role of the nurse academic in practice: a pilot study
Worldwide, health services are interested in supporting the speedy adoption of research findings into practice. To promote the translation of research into practice, a university in the South of England along with a partner NHS Trust piloted a new role â Translation Fellow (TF). This article describes and analyses the experience of piloting this role. This paper outlines the successes achieved as a result of this partnership between a university and a healthcare organisation as well as describing the challenges involved in establishing such a role. The successes included submitting a joint abstract to a conference; collaboratively developing articles for publication; organizing a visit overseas to compare similar services; co-designing a database to assist in collecting data for service planning and research, and setting up a âone click accessâ web space populated with evidence informed material to support the work of the clinical staff. The pilot acted as a proof of concept in which the TF role demonstrated its potential. Additional roles are already being established nationally
Temporal processes in primeâmask interaction: Assessing perceptual consequences of masked information
Visual backward masking is frequently used to study the temporal dynamics of
visual perception. These dynamics may include the temporal features of conscious
percepts, as suggested, for instance, by the asynchronousâupdating model (Neumann, 1982) and perceptualâretouch
theory ((Bachmann, 1994). These models
predict that the perceptual latency of a visual backward mask is shorter than
that of a like reference stimulus that was not preceded by a masked stimulus.
The prediction has been confirmed by studies using temporalâorder judgments: For
certain asynchronies between mask and reference stimulus, temporalâorder
reversals are quite frequent (e.g. Scharlau,
& Neumann, 2003a). However, it may be argued that these
reversals were due to a response bias in favour of the mask rather than true
temporal-perceptual effects. I introduce two measures for assessing latency
effects that (1) are not prone to such a response bias, (2) allow to quantify
the latency gain, and (3) extend the perceptual evidence from order reversals to
duration/interval perception, that is, demonstrate that the perceived interval
between a mask and a reference stimulus may be shortened as well as prolonged by
the presence of a masked stimulus. Consequences for theories of visual masking
such as asynchronousâupdating, perceptualâretouch, and reentrant models are
discussed
The Mere Exposure Effect in the Domain of Haptics
Background: Zajonc showed that the attitude towards stimuli that one had been previously exposed to is more positive than towards novel stimuli. This mere exposure effect (MEE) has been tested extensively using various visual stimuli. Research on the MEE is sparse, however, for other sensory modalities. Methodology/Principal Findings: We used objects of two material categories (stone and wood) and two complexity levels (simple and complex) to test the influence of exposure frequency (F0 = novel stimuli, F2 = stimuli exposed twice, F10 = stimuli exposed ten times) under two sensory modalities (haptics only and haptics & vision). Effects of exposure frequency were found for high complex stimuli with significantly increasing liking from F0 to F2 and F10, but only for the stone category. Analysis of ââNeed for Touchâ â data showed the MEE in participants with high need for touch, which suggests different sensitivity or saturation levels of MEE. Conclusions/Significance: This different sensitivity or saturation levels might also reflect the effects of expertise on the haptic evaluation of objects. It seems that haptic and cross-modal MEEs are influenced by factors similar to those in the visual domain indicating a common cognitive basis
