The Effect of Viewpoint Dependence in Spatial Memory Tasks on Intrusive Memories in Analogue Trauma
No full textPart one of this thesis is a literature review on the use of Imagery Restructuring (IR) within
anxiety disorders. Narrative methods were used to synthesise the findings of 18 studies. The
review details the range of different IR methodology and revealed IR to be an effective
short-term, long-term and preventative technique across different anxiety disorders, reducing
anxiety, imagery and memory related symptomology. However, IR could not be established
as an effective intervention in isolation with long-term therapeutic effects. Given the
heterogeneity of the studies’ methodology, of IR and anxiety pathology, a range of potential
mechanisms underpinning IR are theorised. However, underlying mechanisms were not
explicitly explored in the studies. Finally, the clinical implications of IR and the limitations
of the review are reflected upon before research recommendations are made.
Part two is an empirical study which investigates the effect of egocentric and allocentric
memory processing on intrusive memory (IM) frequency following exposure to analogue
trauma films. Forty five healthy participants were allocated in turn, stratifying for gender to
the egocentric or allocentric recognition memory task group or to the control group.
Participants who undertook an egocentric memory task experienced significantly fewer
intrusive images than the control group (who listened to music). This supports Dual
Representation Theory (DRT) – that intrusive memories are underpinned by relatively
stronger sensory-perceptual egocentric memory representations and relatively weaker
contextualised, allocentric based memory representations. Allocentric memory tasks did not
significantly increase or reduce the number of intrusive memories experienced. Theoretical,
neurobiological and methodological explanations are offered for these findings.
Part three is a critical appraisal which addresses four issues. Firstly, the conceptualisation of
intrusive imagery as being transdiagnostic and on a continuum. Secondly, how the project
prompted the consideration of PTSD as a construct more broadly. Thirdly, the issue of
measuring intrusive memory and considerations for measurement in future research. Finally,
two key learning experiences around ethics of trauma designs and the dynamics of working
with a research assistant
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
COVID-19 welbeing study: A protocol examining perceived coercion and psychological well-being during the COVID-19 pandemic by means of an online survey, asynchronous virtual focus groups and individual interviews
No full textIntroduction The COVID-19 pandemic has resulted in many countries applying restrictive measures, such as lockdown, to contain and prevent further spread. The psychological impact of lockdown and working as a healthcare worker on the frontline has been chronicled in studies pertaining to previous infectious disease pandemics that have reported the presence of depressive symptoms, anxiety, insomnia, and post-traumatic stress symptoms. Potentially linked to psychological well-being and not yet studied is the possibility that lockdown and working on the frontline of the pandemic are associated with perceptions of coercion. Methods and analysis The present study aimed to examine perceived coercion in those who have experienced COVID-19-related lockdown and/or worked as a frontline healthcare worker across three European countries. It aimed to describe how such perceptions may impact on psychological well-being, coping and post-traumatic growth. It will employ an explanatory mixed-methods research methodology consisting of an online survey and online asynchronous virtual focus groups (AVFGs) and individual interviews. χ 2 tests and analyses of variance will be used to examine whether participants from different countries differ according to demographic factors, whether there are differences between cohorts on perceived coercion, depression, anxiety and post-traumatic growth scores. The relationship between coercion and symptoms of distress will be assessed using multiple regression. Both the AVFGs and the narrative interviews will be analysed using thematic narrative analysis. Ethics and dissemination The study has been approved by University College London's Research Ethics Committee under Project ID Number 7335/004. Results will be disseminated by means of peer-reviewed publications and at national and/or international conferences
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
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
