    From Colour to Emotion: Exploring their Association for Mental Health Disorder Digital Interventions

    Background Digital interventions for mental health disorders via smartphones are increasingly popular, particularly cognitive behavioural therapy (CBT) apps, which often incorporate colour as a design element to influence user engagement and emotional regulation. In New Zealand, these innovative interventions have significant potential to provide more affordable and accessible psychological services, especially for rural areas. Colour, as an essential component of design and even interaction, may influence intervention outcomes due to variations in device colour reproduction and individual user preferences. Aim To investigate associations between colour and emotions, and to discuss the consistency of colour reproduction across different smartphones. Methods This study consists of three experiments: (1) Colour-emotion: Participants selected colours on a calibrated screen in a dark room, matching each colour to eight emotion terms—Anger, Desire, Fear, Happiness, Hatred, Jealousy, Love, and Sadness. (2) Colour-music: The procedure was similar to the colour-emotion experiment, and the emotion terms were changed into 26 tracks from Bach's Well-Tempered Clavier. (3) Smartphone colour reproduction: Colour accuracy was measured across Android phones (using Chrome and Firefox browsers) and iPhones (using Chrome and Safari browsers). Results For Colour-emotion test, red frequently corresponded to anger, bright yellow to happiness, and blue to sadness. Also, with the Pleasure-Arousal-Dominance (PAD) model, the dimension of Pleasure emerged as most strongly correlated with colour choices, especially along the brightness and yellow-blue axes. Major-key music corresponded to colour shifts towards higher luminance in the LMS colour space, whereas minor-key music matched colours with lower luminance and increased S cone signal. In terms of colour reproduction on tested smartphones, colour reproduction on iPhones were closer to the original colours used in the test compared to Android phones. Conclusion This study confirms associations between colour and emotion, suggesting potential for colour-based digital mental health interventions. It also highlights the necessity of device-specific calibration, given significant colour reproduction differences across smartphone models and native display settings. Future research should focus on standardising colour presentation to enhance the accuracy and effectiveness of digital psychological tools

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Color in Invertebrate Vision ☆

    Ancestors of all extant invertebrates having color vision have lost during evolution some visual pigments. Arthropod rhabdomeric photoreceptors are inherently polarization sensitive. Other arthropods, such as bees, supress polarization sensitivity of photoreceptors used for color by reorienting microvilli in their rhabdoms.While it is unlikely that insect color vision has been evolutionary adjusted to flower colors, color vision of some butterflies probably coevolved with color of butterfly wings

    Ecology and evolution of primate colour vision

    No full text
    More than one hundred years ago, Grant Allen suggested that colour vision in primates, birds and insects evolved as an adaptation for foraging on colourful advertisements of plants-fruits and flowers. Recent studies have shown that well developed colour vision appeared long before fruits and flowers evolved. Thus, colour vision is generally beneficial for many animals, not only for those eating colourful food. Primates are the only placental mammals that have trichromatic colour vision. This may indicate either that trichromacy is particularly useful for primates or that primates are unique among placental mammals in their ability to utilise the signals of three spectrally distinct types of cones or both. Because fruits are an important component of the primate diet, primate trichromacy could have evolved as a specific adaptation for foraging on fruits. Alternatively, primate trichromacy could have evolved as an adaptation for many visual tasks. Comparative studies of mammalian eyes indicate that primates are the only placental mammals that have in their retina a pre-existing neural machinery capable of utilising the signals of an additional spectral type of cone. Thus, the failure of non-primate placental mammals to evolve trichromacy can be explained by constraints imposed on the wiring of retinal neurones

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
