Recognising and addressing health misinformation in nursing practice

Misleading and inaccurate health information increasingly being shared within the public domain, particularly via social media platforms. This can result in negative real-world consequences, particularly in the context of the coronavirus disease 2019 (COVID-19) pandemic. Nurses and other healthcare professionals need to be aware of those people who are susceptible to believing false information and be prepared to have open conversations with patients about what they may have read or heard about health-related matters. Correcting disinformation and misinformation can be complex as it is often based on part truths and if handled inappropriately can risk causing the belief to become further embedded. This article provides nurses with information and resources to address incorrect information in clinical practice, as well as highlighting strategies for debunking online myths

Edge-enhanced disruptive camouflage impairs shape discrimination

Disruptive colouration (DC) is a form of camouflage comprised of areas of pigmentation across a target’s surface that form false edges, which are said to impede detection by disguising the outline of the target. In nature, many species with DC also exhibit edge enhancement (EE); light areas have lighter edges and dark areas have darker edges. EE DC has been shown to undermine not only localisation but also identification of targets, even when they are not hidden (Sharman, Moncrieff, & Lovell, 2018). We use a novel task, where participants judge which “snake” is more “wiggly,” to measure shape discrimination performance for three colourations (uniform, DC, and EE DC) and two backgrounds (leafy and uniform). We show that EE DC impairs shape discrimination even when targets are not hidden in a textured background. We suggest that this mechanism may contribute to misidentification of EE DC targets

Dissociating the effect of disruptive colouration on localisation and identification of camouflaged targets

Disruptive camouflage features contrasting areas of pigmentation across the animals’ surface that form false edges which disguise the shape of the body and impede detection. In many taxa these false edges feature local contrast enhancement or edge enhancement, light areas have lighter edges and dark areas have darker edges. This additional quality is often overlooked in existing research. Here we ask whether disruptive camouflage can have benefits above and beyond concealing location. Using a novel paradigm, we dissociate the time courses of localisation and identification of a target in a single experiment. We measured the display times required for a stimulus to be located or identified (the critical duration). Targets featured either uniform, disruptive or edge enhanced disruptive colouration. Critical durations were longer for identifying targets with edge enhanced disruptive colouration camouflage even when presented against a contrasting background, such that all target types were located equally quickly. For the first time, we establish empirically that disruptive camouflage not only conceals location, but also disguises identity. This shows that this form of camouflage can be useful even when animals are not hidden. Our findings offer insights into how edge enhanced disruptive colouration undermines visual perception by disrupting object recognition

Luminance cues constrain chromatic blur discrimination in natural scene stimuli

Introducing blur into the color components of a natural scene has very little effect on its percept, whereas blur introduced into the luminance component is very noticeable. Here we quantify the dominance of luminance information in blur detection and examine a number of potential causes. We show that the interaction between chromatic and luminance information is not explained by reduced acuity or spatial resolution limitations for chromatic cues, the effective contrast of the luminance cue, or chromatic and achromatic statistical regularities in the images. Regardless of the quality of chromatic information, the visual system gives primacy to luminance signals when determining edge location. In natural viewing, luminance information appears to be specialized for detecting object boundaries while chromatic information may be used to determine surface properties

Should Teamwork-Based Content be Taught in the Cal Poly Construction Management Curriculum?

At California Polytechnic State University, San Luis Obispo (Cal Poly), in the Construction Management (CM) curriculum, there is a lack of teamwork-based content. This content includes negotiation, conflict resolution, and fundamental skills for working collaboratively with others such as social-emotional intelligence, empathy, and communication. The nature of the Cal Poly CM Program is to teach students about the aspects of the construction process, however what is missed is teaching how to work effectively in teams. They fail to teach this because of the strict curriculum of focusing on learning objectives rather than teaching individuals how to be effective construction managers. The purpose of this paper is to determine if teamwork-based content should be taught in the CM curriculum. The research was conducted by utilizing a five question survey sent out to all current CM students. This survey will gauge the need for teamwork-based content based on the students’ opinions. Of the 52 who responded, more than 75% of them are in agreement that teamwork-based content needs to be taught within the CM curriculum. The Cal Poly CM department needs to seriously consider this type of content in their program

Racehorses are getting faster

ArticleData used for analyses in this manuscript are available in Dryad: http://dx.doi.org/10.5061/dryad.qn82p.Copyright © 2015 The Author(s) Published by the Royal Society. All rights reserved.Previous studies have concluded that thoroughbred racehorse speed is improving very slowly, if at all, despite heritable variation for performance and putatively intensive selective breeding. This has led to the suggestion that racehorses have reached a selection limit. However, previous studies have been limited, focussing only on the winning times of a few elite races run over middle and long distances, and failing to account for potentially confounding factors. Using a much larger dataset covering the full range of race distances and accounting for variation in factors such as ground softness, we show that improvement is in fact on-going for the population as a whole, but driven largely by increasing speed in sprint races. In contrast, speed over middle and long distances, at least at the elite level, appears to be reaching an asymptote. Whether this reflects a selection limit to speed over middle and long distances or a shift in breeding practices to target sprint performances remains to be determined.BBSRC David Phillips Fellowshi

The role of motion and number of element locations in mirror symmetry perception

The human visual system has specialised mechanisms for encoding mirror-symmetry and for detecting symmetric motion-directions for objects that loom or recede from the observers. The contribution of motion to mirror-symmetry perception has never been investigated. Here we examine symmetry detection thresholds for stationary (static and dynamic flicker) and symmetrically moving patterns (inwards, outwards, random directions) with and without positional symmetry. We also measured motion detection and direction-discrimination thresholds for horizontal (left, right) and symmetrically moving patterns with and without positional symmetry. We found that symmetry detection thresholds were (a) significantly higher for static patterns, but there was no difference between the dynamic flicker and symmetrical motion conditions, and (b) higher than motion detection and direction-discrimination thresholds for horizontal or symmetrical motion, with or without positional symmetry. In addition, symmetrical motion was as easy to detect or discriminate as horizontal motion. We conclude that whilst symmetrical motion per se does not contribute to symmetry perception, limiting the lifetime of pattern elements does improve performance by increasing the number of element-locations as elements move from one location to the next. This may be explained by a temporal integration process in which weak, noisy symmetry signals are combined to produce a stronger signal

Utilisation of intranets for knowledge sharing : a socio-technical study

Although intranets appear to be ideal environments for employees to share knowledge quickly and efficiently, usage in practice appears limited. We report findings from two case studies that highlight three key issues limiting intranet utilisation for knowledge sharing: organisational structures and strategies, the impact of the receiver on sharer choices, and the availability of alternative channels for knowledge sharing. This study suggests that for companies to obtain more effective intranets, they need to better align organisational structures and strategies with intranet objectives, develop a comprehensive corporate communication plan, and find new ways to better link sharers with receivers&rsquo; knowledge needs.<br /

Psychosocial correlates in treatment seeking gamblers: Differences in early age onset gamblers vs later age onset gamblers

Background Age of onset is an important factor in the development and trajectory of psychiatric disorders; however, little is known regarding the age of onset in relation to disordered gambling in treatment seeking samples in the UK. Utilising a large residential treatment seeking gambler cohort, the current study examined the relationship between age of gambling onset and a range of variables thought to be associated with disordered gambling. Method Data were collected from 768 gamblers attending residential treatment for disordered gambling. Individuals were grouped per the age they started gambling as either a child (≤12), adolescent (13–15), or young adult/adult (≤16). Data were analysed using linear, backward stepwise, and multinomial logistic regressions to identify significant relationships between age of onset and variables of theoretical significance. Results Results indicate the younger age of gambling onset was associated with increased gambling severity. Those who began gambling at an earlier age were more likely to have abused drugs or solvents, committed an unreported crime, been verbally aggressive and experienced violent outbursts. They are less likely to report a positive childhood family environment and are more likely to have had a parent with gambling and/or alcohol problems. Discussion Gamblers who began gambling at an earlier age experience negative life events and exhibit some antisocial behaviors more than later onset gamblers, indicating that when addressing gambling behavior, it is important to consider the developmental trajectory of the disorder, rather than merely addressing current gambling behavior. However, the direction of the relationship between gambling and significant variables is in some instance unclear, indicating a need for further research to define causality

IT security certifications : stakeholder evaluation and selection

Information technology (IT) security certifications have proliferated in recent years. However they differ in regards to stakeholder considerations of credibility, accessibility and relevance. Key stakeholders with an interest in selecting an IT security certification (IT security professionals, employers, governments and higher education institutes) lack a systematic approach for differentiating between candidate certifications and selecting the &ldquo;best&rdquo; certification to satisfy requirements. The paper focuses on reporting a confirmatory focus group from a recent research project. It provides a framework for supporting stakeholder evaluation and selection of IT security certifications and discusses key implications for the IT security industry, IT security certifications, and the higher education sector.<br /
