Imaginator
No full textAims
Self-harm affects around 20% of all young people in the UK. Treatment options for self-harm remain limited and those available are either non-specific or long and costly and may not suit all young people. There is an urgent need to develop new scalable interventions to address this gap.
Imaginator is a novel imagery-based intervention targeting self-harm initially developed for 16–25-year-olds. It is a blended digital intervention delivering Functional Imagery Training (FIT) via therapist sessions and a smartphone app. In this study we piloted a new version of Imaginator extended to adolescents from age 12 after co-producing a new app with a diverse group of young people experts-by-experience.
We aimed to assess feasibility of delivering Imaginator in Children and Adolescent Mental Health Services (CAMHS) and adult secondary mental health services and gather young people's feedback on the intervention
Methods
Participants were recruited from West London NHS Trust Tier 2 CAMHS and adult Mental health Integrated Network Teams (MINT) teams. They underwent a baseline screening and were allocated to a therapist for three face-to-face FIT sessions in which the app was introduced followed by five phone support sessions. Outcome assessments were conducted after completing therapy, approximately 3-months post-baseline, including questionnaire measures and a qualitative feedback interview.
Qualitative data were analysed using a co-produced thematic analysis method with lived experience co-researchers.
Results
Thirty-four participants were referred (31 female, 2 male, 1 transgender; mean age = 18.4), of which 30 met inclusion criteria and completed screening. Out of 25 who started therapy 16 completed the intervention. Only 15 completed the quantitative outcome assessment, and 10 the interviews. There was an overall reduction in number of self-harm episodes over 3-months from pre- to post-intervention
Five main themes were identified: Imaginator therapy impact, mental imagery acceptability and efficacy, usefulness and usability of the app, integration of the app in therapy and need for improvements. Young people found Imaginator helpful at improving their mental health, in particular the use of mental imagery techniques. The app was overall well received but improvements were suggested.
Conclusion
Our study suggests that Imaginator can be extended to adolescents, is acceptable and has potential as a brief intervention reducing self-harm in young people under mental health services. A future RCT is needed to robustly test the intervention efficacy, after considering issues around high attrition in outcome measures
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
ImaGINator: Conditional Spatio-Temporal GAN for Video Generation
No full textInternational audienceGenerating human videos based on single images entails the challenging simultaneous generation of realistic and visual appealing appearance and motion. In this context, we propose a novel conditional GAN architecture, namely ImaGINator, which given a single image, a condition (la-bel of a facial expression or action) and noise, decomposes appearance and motion in both latent and high level feature spaces, generating realistic videos. This is achieved by (i) a novel spatio-temporal fusion scheme, which generates dynamic motion, while retaining appearance throughout the full video sequence by transmitting appearance (originating from the single image) through all layers of the network. In addition, we propose (ii) a novel transposed (1+2)D convo-lution, factorizing the transposed 3D convolutional filters into separate transposed temporal and spatial components, which yields significantly gains in video quality and speed. We extensively evaluate our approach on the facial expression datasets MUG and UvA-NEMO, as well as on the action datasets NATOPS and Weizmann. We show that our approach achieves significantly better quantitative and qualitative results than the state-of-the-art
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
No full textWe 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
