Using Icon Arrays to Communicate Gambling Information Reduces the Appeal of Scratch Card Games.

Past work has demonstrated that presenting statistical information in a foreground-background icon array can improve risk understanding, reduce decision-making biases, and decrease the salience of low-probability risks. In the present study, we assess whether presenting readily available gambling information within a foreground-background icon array influences individuals' gambling-related judgments (e.g., their perceived likelihood of winning a prize). Across two experiments (N = 1151), we find that using icon arrays to present gambling information reduces the appeal of scratch card games. That is, participants presented with gambling information in a foreground-background icon array, as opposed to a non-graphical numerical format, reported feeling less likely to win a prize, less excitement to play, and less urge to gamble on a scratch card game presented in a hypothetical gambling task. Overall, we conclude that presenting gambling information in an icon array format represents a simple yet promising tool for correcting gamblers' often overly-optimistic perceptions and reducing the appeal of negative expected value scratch card games.

Polish norms for a set of colored drawings of 168 objects and 146 actions with predictors of naming performance.

In this study, we present the first database of pictures and their corresponding psycholinguistic norms for Polish: the CLT database. In this norming study, we used the pictures from Cross-Linguistic Lexical Tasks (CLT): a set of colored drawings of 168 object and 146 actions. The CLT pictures were carefully created to provide a valid tool for multicultural comparisons. The pictures are accompanied by norms for Naming latencies, Name agreement, Goodness of depiction, Image agreement, Concept familiarity, Age of acquisition, Imageability, Lexical frequency, and Word complexity. We also report analyses of predictors of Naming latencies for pictures of objects and actions. Our results show that Name agreement, Concept familiarity, and Lexical frequency are significant predictors of Naming latencies for pictures of both objects and actions. Additionally, Age of acquisition significantly predicts Naming latencies of pictures of objects. The CLT database is freely available at osf.io/gp9qd. The full set of CLT pictures, including additional variants of pictures, is available on request at osf.io/y2cwr.

Digital 2D, 2.5D and 3D Methods for Adding Photo-Realistic Textures to 3D Facial Depictions of People from the Past.

Facial reconstruction is a technique that can be used to estimate individual faces from human skulls. The presentation of 3D facial reconstructions as photo-realistic depictions of people from the past to public audiences varies widely due to differing methods, the artists' CGI skillset, and access to VFX software required to generate plausible faces.This chapter describes three digital methods for the addition of realistic textures to 3D facial reconstructions; a 2D photo-composite method, a 3D digital painting and rendering method, and a previously undescribed hybrid 2.5D method.These methods are compared and discussed in relation to artistic proficiency, morphological accuracy and practitioner bias.

Entertainment-Education: What Are Grey's Anatomy and Saving Hope Teaching Us About Death?

In this article, we examine primetime television as a source of entertainment-education on death. Using directed (deductive) and conventional (inductive) approaches to content analysis, we describe how death and dying are being depicted on two primetime medical television series, Grey's Anatomy and Saving Hope. We then discuss what kinds of information viewers may be taking from these series. Our deductive content analysis suggests that much of the messages obtained are fairly representative of what occurs in real hospital settings, with the exception of emotional display. From the inductive analysis, we identified four thematic categories: 'the person dies, but life goes on', 'the tragic death', 'the purposeful death', and 'the well-timed death'. Regardless of category, no rituals are conducted at the moment of death and little space is made for grieving on primetime medical television shows. While death is often present, displays of grief are avoided.

Disruption and bactericidal indices depicted in polygonal graphs to show multiple outcome effects of root canal irrigant supplements on single- and dual-species biofilms.

OBJECTIVES: The aims of this study were to (1) investigate the relative time-dependent disruption and bactericidal effects of detergent-type surfactants on single- or dual-species biofilms of root canal isolates and (2) to examine the utility of polygonal graphs for depiction of biofilm disruption and cell killing. MATERIALS AND METHODS: Single-species biofilms of Streptococcus sanguinis, Enterococcus faecalis, Fusobacterium nucleatum and Porphyromonas gingivalis were grown on nitro-cellulose membranes for 72 h and immersed in Tween®80, cetyltrimethylammoniumbromide (CTAB), and sodium dodecyl sulphate (SDS) for 1-, 5- or 10-min (n = 3 per test). The number of viable and non-viable bacteria "disrupted" from the biofilm and those "remaining-attached" was determined using a viability stain in conjunction with fluorescence microscopy. The data were analysed using non-parametric Kruskal-Wallis test with 5% significance level. RESULTS: Gram-negative obligate anaerobes were more susceptible to cell removal than gram-positive facultative anaerobes. The majority of cells were disrupted after 1-min of exposure; however, the extent varied according to the agent and species. CTAB and SDS were more effective than Tween 80™ at disrupting biofilms and killing cells but all agents failed to achieve 100% disruption/kill. CONCLUSIONS: Biofilm disruption and cell viability were influenced by the species, the test agent and the duration of exposure. CTAB and SDS were more effective in biofilm disruption than Tween 80™. Graphical depiction of biofilm disruption- and viability-outcomes provides an alternative means of simultaneously visualising and analysing relative efficacy in different domains. CLINICAL RELEVANCE: Surfactants were not as effective at biofilm disruption as NaOCl but may be added to other non-disruptive antibacterial agents to enhance this property.

The Affordances of 3D and 4D Digital Technologies for Computerized Facial Depiction.

3D digital technologies have advanced rapidly over recent decades and they can now afford new ways of interacting with anatomical and cultural artefacts. Such technologies allow for interactive investigation of visible or non-observable surfaces, haptic generation of content and tactile experiences with digital and physical representations. These interactions and technical advances often facilitate the generation of new knowledge through interdisciplinary and sympathetic approaches.Scientific and public understanding of anatomy are often enhanced by clinical imaging technologies, 3D surface scanning techniques, 3D haptic modelling methods and 3D fabrication systems. These digital and haptic technologies are seen as non-invasive and allow scientists, artists and the public to become active investigators in the visualisation of, and interaction with, human anatomy, remains and histories.Face Lab is a Liverpool John Moores University research group that focuses on creative digital face research; specifically the further development of a 3D computerized craniofacial depiction system, utilizing 3D digital technologies in facial analysis and identification of human remains for forensic investigation, or historical figures for archaeological interpretation.This chapter explores the affordances of such interactions for the non-destructive production of craniofacial depiction, through a case-study based exploration of Face Lab workflow.

Threefoldness.

Theories of picture perception aim to understand our perceptual relation to both the picture surface and the depicted object. I argue that we should talk about not two, but three entities when understanding picture perception: (A) the picture surface, (B) the three dimensional object the picture surface visually encodes and (C) the three dimensional depicted object. As (B) and (C) can come apart, we get a more complex picture of picture perception than normally assumed and one where the notion of twofoldness, which has played an important albeit controversial role in understanding picture perception is replaced by the concept of threefoldness.

Epilepsy through the ages: An artistic point of view.

The historical allure of epilepsy transcends academic circles and serves as fascinating critique of the state of the times-its values, judgments, mythos, and people. Immortalized and laid bare in artistic renderings of epilepsy are societal truths, at times both disparately grandiose and grotesque. During the middle ages and Renaissance, the European discourse on epilepsy assumed religious fervor. Epilepsy was considered a demonic machination and its cure an act of divine intercession. A similar theme is found in the artistic depiction of epilepsy from the Inca and Aztec civilizations of that time. After the 19th century drew to a close, the ascendency of empiricism coincided with waning creative interest in epilepsy, with few paintings or pieces to capture insightful perspectives on the illness. In this paper, we review the relationship between art and epilepsy and present two contemporary paintings that convey current western perceptions. This article is part of a Special Issue entitled "Epilepsy, Art, and Creativity".

The Doppelgänger effect? A comparative study of forensic facial depiction methods.

This study attempted to assess the reproducibility of 2D and 3D forensic methods for facial depiction from skeletal remains (2D sketch, 3D manual, 3D automated, 3D computer-assisted). In a blind study, thirteen practitioners produced fourteen facial depictions, using the same skull model derived from CT data of a living donor, a biological profile and relevant soft tissue data. The facial depictions were compared to the donor subject using three different evaluation methods: 3D geometric, 2D face recognition ranking and familiar resemblance ratings. Five of the 3D facial depictions (all 3D methods) demonstrated a deviation error within ± 2 mm for ≥ 50% of the total face surface. Overall, no single 3D method (manual, computer assisted, automated) produced consistently high results across all three evaluations. 2D comparisons with a facial photograph of the donor were carried out for all the 2D and 3D facial depictions using four freely available face recognition algorithms (Toolpie; Photomyne; Face ++; Amazon). The 2D sketch method produced the highest ranked matches to the donor photograph, with overall ranking in the top six. Only one 3D facial depiction was ranked highly in both the 3D geometric and 2D face recognition comparisons. The majority (67%) of the facial depictions were rated as limited or moderate resemblance by the familiar examiner. Only one 2D facial depiction was rated as strong resemblance, whilst two 2D sketches and two 3D facial depictions were rated as good resemblances by the familiar examiner. The four most geometrically accurate 3D facial depictions were only rated as limited or moderate resemblance to the donor by the familiar examiner. The results suggest that where a consistent facial depiction method is utilised, we can expect relatively consistent metric reliability between practitioners. However, presentation standards for practitioners would greatly enhance the possibility of recognition in forensic scenarios.

On the (in)effectiveness of textual disclosures on expectancies, attitudes, and perceived appropriateness of alcohol.

OBJECTIVE: Drinking alcohol is frequently portrayed in the media, often overemphasizing its positive attributes. In particular, hip-hop music videos regularly depict alcohol consumption. Building on social cognitive theory, we conduct three pre-registered experimental studies to examine whether textual disclosures from different sources and with varying degrees of explicitness about the consequences of alcohol consumption can influence viewers' alcohol expectancies, attitudes toward alcohol, and the appropriateness of alcohol presentations following a hip-hop video depicting alcohol consumption. METHODS AND MEASURES: We test 1) the established YouTube product placement disclosure, 2) a disclosure that explicitly refers to alcohol and a disclosure that additionally refers to the harmful consequences of alcohol consumption, 3) and finally the role of user comments on YouTube that discuss the negative or positive consequences of alcohol. RESULTS: We found that none of the disclosures tested were able to reduce positive attitudes toward alcohol, positive drinking expectancies, or perceived appropriateness of alcohol portrayals. Instead, one's own drinking behavior was most important in explaining these dependent variables, with frequent drinkers reporting higher scores on attitudes toward alcohol, positive drinking expectancies, and a positive evaluation of alcohol portrayals in the media compared to people who never or rarely drink. CONCLUSIONS: Our findings across the three studies paint a picture of the ineffectiveness of various forms of textual disclosure on alcohol-related attitudes, expectancies, and ratings of the appropriateness of alcohol portrayals in the media. Alternative steps forward, i.e., the creation of offerings for content creators that encourage them to consider the consequences of their representations, are therefore needed.

Trauma and mental disorder: multi-perspective depictions in Top Boy.

Psychiatry has often had an uneasy relationship with popular culture as depictions of mental health may be stigmatising and inaccurate. A recent critically acclaimed series, Top Boy, set in a crime-filled fictional housing estate in the London Borough of Hackney offers an informed and fairly balanced insight into broad mental health-related themes including racial trauma embodied in social inequities, the syndemic of mental disorder, substance misuse and gang-based crime as well as the psychosocial ramifications of illustrated mental health conditions. From both idiographic and nomothetic perspectives, Top Boy touches on a rich variety of structural determinants of mental health, as well as individual and environmental predisposition to mental disorder and substance misuse. The show offers an opportunity for education for both the broader society and the groups which suffer these syndemics. An understanding of how structural factors epidemiologically affect what psychiatric conditions individuals are likely to suffer, how they can be better reached by psychiatric services, and what interventions can help improve the socioeconomic factors that lead to the behaviours/paths that individuals end up is vital for public mental health policy.

Mocking enactments: a case study of multimodal stance-stacking.

Although research into multimodal stance-taking has gained momentum over the past years, the multimodal construction of so-called stacked stances has not yet received systematic attention in the literature. Mocking enactments are a prime example of such complex social actions as they are layered both interactionally and stance-related, and they rely significantly on the use of bodily visual resources, depicting rather than describing events and stances. Using Du Bois' Stance Triangle as a framework, this study investigates mocking enactments as a case study to unravel the multimodal aspects of layered stance expressions. Drawing on three data sets-music instruction in Dutch, German, and English, spontaneous face-to-face interactions among friends in Dutch, and narrations on past events in Flemish Sign Language (VGT)-this study provides a qualitative exploration of mocking enactments across different communicative settings, languages, and modalities. The study achieves three main objectives: (1) illuminating how enactments are used for mocking, (2) identifying the layers of stance-taking at play, and (3) examining the multimodal construction of mocking enactments. Our analysis reveals various different uses of enactments for mocking. Aside from enacting the target of the mockery, participants can include other characters and viewpoints, highlighting the breadth of the phenomenon under scrutiny. Second, we uncover the layered construction of stance on all axes of the Stance Triangle (evaluation, positioning, and alignment). Third, we find that mocking enactments are embedded in highly evaluative contexts, indexed by the use of bodily visual resources. Interestingly, not all mocking enactments include a multimodally exaggerated depiction, but instead, some merely allude to an absurd hypothetical scenario. Our findings contribute to the growing body of literature on multimodal stance-taking, by showing how a nuanced interpretation of the Stance Triangle can offer a useful framework for analyzing layered stance acts.

pyPept: a python library to generate atomistic 2D and 3D representations of peptides.

We present pyPept, a set of executables and underlying python-language classes to easily create, manipulate, and analyze peptide molecules using the FASTA, HELM, or recently-developed BILN notations. The framework enables the analysis of both pure proteinogenic peptides as well as those with non-natural amino acids, including support to assemble a customizable monomer library, without requiring programming. From line notations, a peptide is transformed into a molecular graph for 2D depiction tasks, the calculation of physicochemical properties, and other systematic analyses or processing pipelines. The package includes a module to rapidly generate approximate peptide conformers by incorporating secondary structure restraints either given by the user or predicted via pyPept, and a wrapper tool is also provided to automate the generation and output of 2D and 3D representations of a peptide directly from the line notation. HELM and BILN notations that include circular, branched, or stapled peptides are fully supported, eliminating errors in structure creation that are prone during manual drawing and connecting. The framework and common workflows followed in pyPept are described together with illustrative examples. pyPept has been released at: https://github.com/Boehringer-Ingelheim/pyPept .

The politics of face and the trouble with race: Exploring relations at the interface between the individual and the collective in forensic practice.

This special issue interrogates race through the lens of face. Its central faces are those in forensic settings. Promising immediate legibility and access to the individual suspect, forensic faces nevertheless mobilize a variety of collectives. We offer conceptual and methodological tools to examine the face as both an individual and a collective phenomenon, and demonstrate through detailed cases how the face thus allows us to address the absent presence of race. Given its long and convoluted history in physical anthropology, as a marker of racial typology, the face forces us to reckon with colonial histories of ordering human difference. But the face also allows us to question a regime of visuality that congeals around the face in Western culture. In this introduction to The Politics of Face and the Trouble with Race we elaborate these concerns and introduce the contributions to this volume.

On the persistence of race: Unique skulls and average tissue depths in the practice of forensic craniofacial depiction.

The (re-)surfacing of race in forensic practices has received plenty of attention from STS scholars, especially in connection with modern forensic genetic technologies. In this article, I describe the making of facial depictions based on the skulls of unknown deceased individuals. Based on ethnographic research in the field of craniofacial identification and forensic art, I present a material-semiotic analysis of how race comes to matter in the face-making process. The analysis sheds light on how race as a translation device enables oscillation between the individual skull and population data, and allows for slippage between categories that otherwise do not neatly map on to one another. The subsuming logic of race is ingrained - in that it sits at the bases of standard choices and tools - in methods and technologies. However, the skull does not easily let itself be reduced to a racial type. Moreover, the careful efforts of practitioners to articulate the individual characteristics of each skull provide clues for how similarities and differences can be done without the effect of producing race. Such methods value the skull itself as an object of interest, rather than treat it as a vehicle for practicing race science. I argue that efforts to undo the persistence of race in forensic anthropology should focus critical attention on the socio-material configuration of methods and technologies, including data practices and reference standards.

Changes in tobacco imagery and smokers' depiction in Spanish top-grossing films before and after the implementation of a comprehensive tobacco control policy in Spain.

INTRODUCTION: As more restrictions on tobacco marketing communication are implemented, tobacco marketing has persisted through smoking in films. Our aims were to assess changes in tobacco imagery exposure in Spanish top-grossing films before and after the banning of tobacco advertising in Spain, and to determine whether the depiction of smoking characters has changed over the years. METHODS: A repeated cross-sectional study measured the tobacco content in the 10 Spanish top-grossing films in 2005, 2010 and 2015 (n=30) before and after a complete tobacco advertising ban. We conducted a descriptive and regression analysis of changes in tobacco impressions by year. RESULTS: The 30 films contained 1378 tobacco occurrences (90.2% positive for tobacco) with a median length of eight seconds onscreen. Total tobacco occurrences deemed positive for tobacco interests significantly increased in 2010 and 2015 compared to 2005. However, we observed decreased odds of tobacco brands appearances (OR=0.25; p<0.001) in 2010 and of implied tobacco use (OR=0.44; p=0.002), and tobacco brands appearances (OR=0.36; p<0.001) in 2015 compared to 2005. There was a change of pattern in the type of role smokers played from a leading role to a supporting one (p<0.001). The population reach of positive for tobacco occurrence in Spanish top-grossing films decreased from 15.9 (95% CI: 15.86-15.86) per 1000 spectators in 2005 to 0.8 (95% CI: 0.82-0.82) in 2015. CONCLUSIONS: The implementation of a ban on complete tobacco product advertising was followed by a decrease in tobacco incidents across top-grossing Spanish films. Yet, exposure to smoking in films is still unacceptably high.

Small calcification indicator in ultrasonography using correlation of echoes with a modified Wiener filter.

PURPOSE: The purpose of this study is to improve the calcification depiction ability in ultrasonography using correlation of echoes with a modified Wiener filter. METHODS: The waveform of an ultrasound pulse changes when it passes through the location of a calcification. Since the change in echo waveform caused by a calcification decreases the correlation of waveforms in adjacent scan lines, we have proposed a calcification depiction method using the decorrelation of echoes. However, the low signal-to-noise ratio of echoes also decreases the correlation of the echoes. In this study, we employ the correlation of echoes with a modified Wiener filter to suppress the effect of noise, as an indicator of a calcification. RESULTS: The proposed calcification indicator depicted copper cylindrical rods 0.2 mm in size at a depth of 2 cm with a sensitivity of 80% and a positive predictive value of 80%, despite being hardly depicted at all on B-mode ultrasound imaging. CONCLUSION: This study suggests the potential of the proposed method to improve the performance of calcification depiction by ultrasound devices.

RanDepict: Random chemical structure depiction generator.

The development of deep learning-based optical chemical structure recognition (OCSR) systems has led to a need for datasets of chemical structure depictions. The diversity of the features in the training data is an important factor for the generation of deep learning systems that generalise well and are not overfit to a specific type of input. In the case of chemical structure depictions, these features are defined by the depiction parameters such as bond length, line thickness, label font style and many others. Here we present RanDepict, a toolkit for the creation of diverse sets of chemical structure depictions. The diversity of the image features is generated by making use of all available depiction parameters in the depiction functionalities of the CDK, RDKit, and Indigo. Furthermore, there is the option to enhance and augment the image with features such as curved arrows, chemical labels around the structure, or other kinds of distortions. Using depiction feature fingerprints, RanDepict ensures diversely picked image features. Here, the depiction and augmentation features are summarised in binary vectors and the MaxMin algorithm is used to pick diverse samples out of all valid options. By making all resources described herein publicly available, we hope to contribute to the development of deep learning-based OCSR systems.

Investigating reverse osmosis membrane fouling and scaling by membrane autopsy of a bench scale device.

In response to the escalating world water demand and aiming to promote equal opportunities, reverse osmosis desalination has been widely implemented. Desalination is however constantly subjected to fouling and scaling which increase the cost of desalination by increasing the differential pressure of the membrane and reducing the permeate flux. A bench-scale desalination equipment has been used in this research to investigate the mitigation of fouling and scaling. This study involved the performance of membrane autopsy for fouling characterisation with special attention to flux decline due to sulphate precipitation and biofouling. Visual inspection, scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and microbiology tests (API) were performed. Results obtained showed the presence of diatoms, pseudomonas and polysaccharides as the main foulants causing biofouling. Analysis revealed sulphate deposits as well as aluminium, calcium and silica as the main elements contributing to inorganic scaling. Findings pointed out that the pre-treatment system of the small-scale reverse osmosis water treatment was inefficient and that selection of pre-treatment chemicals should be based on its compatibility with the membrane structure. The importance of characterisation for the verification of fouling mechanisms is emphasised.

Research pedagogy in a UK radiography education setting.

INTRODUCTION: This paper focuses on research pedagogy in radiography and the importance of research for the profession by exploring one university's endeavours to realise the aims of The Society and College of Radiographers Research Strategy 2016-20211 around embedding research in the curriculum. METHODS: Co-Constructed Depiction method was developed as an innovative use of imagery in data collection, analysis, and presentation of results, being symbolic of the practices of the radiography profession by foregrounding the importance of images and their interpretation. A total of eighteen radiography staff, post-graduate radiography students, and 3rd year radiography undergraduate students from both Diagnostic and Therapeutic professional backgrounds and courses took part in individual semi-structured interviews that included participant image making. RESULTS: Students and educators saw the importance of research for individuals and the profession. While students could identify where research was embedded in the curriculum, generally staff did not feel embedding was done well, but this may be because research is not made explicit enough in the curriculum. Participants suggested that research needs to become 'normalised'; being a part of all radiographers' work. CONCLUSION: The links between research, professionalism, and care can be made more evident to students from the start of their studies so increasing understanding of their own relationship with the spectrum of research, and how this links to maintaining the standing of our profession and to patient care. IMPLICATIONS FOR PRACTICE: The findings will inform future research pedagogy and undergraduate curriculum development in radiography and other Allied Health Professions around embedding research in the curriculum in a way that educators and students recognise.
