Alternative Factor Models and Heritability of the Short Leyton Obsessional Inventory-Children's Version

An alternative models framework was used to test three confirmatory factor analytic models for the Short Leyton Obsessional Inventory-Children's Version (Short LOI-CV) in a general population sample of 517 young adolescent twins (11-16 years). A one-factor model as implicit in current classification systems of Obsessive-Compulsive Disorder (OCD), a two-factor obsessions and compulsions model, and a multidimensional model corresponding to the three proposed subscales of the Short LOI-CV (labelled Obsessions/Incompleteness, Numbers/Luck and Cleanliness) were considered. The three-factor model was the only model to provide an adequate explanation of the data. Twin analyses suggested significant quantitative sex differences in heritability for both the Obsessions/Incompleteness and Numbers/Luck dimensions with these being significantly heritable in males only (heritability of 60% and 65% respectively). The correlation between the additive genetic effects for these two dimensions in males was 0.95 suggesting they largely share the same genetic risk factors.

The Queen's Shilling:A collaboration with Goldin+Senneby

A performance art piece in the Centre for Contemporary Art, Derry/Londonderry as part of the City of Culture. International conceptual artists Goldin+Senneby commissioned me to write a short play inspired by their obsessions with alchemy, royalty and the financial markets. The play dramatises the suffering of Queen Elizabeth II as she confronts her own mortality in a world where she is an immortal symbol. Through a conversation with her predecessor Elizabeth I, she reveals that the whole stability of the financial system rests on the weight of her daily effluvia.

Approche autofictionnelle de l'homosexualite dans l'oeuvre romanesque de Conrad Detrez. Allusion, latence et chastete

Conrad Detrez does not write ―gay novels‖ as literary critique sees this expression nowadays. However, through self-fiction, Detrez´s novels present an allusive, latent and prudish approach of this topic, which is essential in the author and narrator‘s obsessions

I Believe in me, not OCB: Evaluation of Group Function-Based CBT as a Treatment for Obsessive Compulsive Behaviour in Four Children with HFA

Researchers have conceptualized repetitive behaviours in individuals with Autism Spectrum Disorder (ASD) on a continuum oflower-Ievel, motoric, repetitive behaviours and higher-order, repetitive behaviours that include symptoms ofOCD (Hollander, Wang, Braun, & Marsh, 2009). Although obsessional, ritualistic, and stereotyped behaviours are a core feature of ASD, individuals with ASD frequently experience obsessions and compulsions that meet DSM-IV-TR (American Psychiatric Association, 2000) criteria for Obsessive-Compulsive Disorder (OCD). Given the acknowledged difficulty in differentiating between OCD and Autism-related obsessive-compulsive phenomena, the present study uses the term Obsessive Compulsive Behaviour (OCB) to represent both phenomena. This study used a multiple baseline design across behaviours and ABC designs (Cooper, Heron, & Heward, 2007) to investigate if a 9-week Group Function-Based Cognitive Behavioural Therapy (CBT) decreased OCB in four children (ages 7 - 11 years) with High Functioning Autism (HFA). Key treatment components included traditional CBT components (awareness training, cognitive-behavioural skills training, exposure and response prevention) as well as function-based assessment and intervention. Time series data indicated significant decreases in OCBs. Standardized assessments showed decreases in symptom severity, and increases in quality of life for the participants and their families. Issues regarding symptom presentation, assessment, and treatment of a dually diagnosed child are discussed.

Evaluating Knowledge of a Function-based Cognitive-Behavioural Treatment for Obsessive Compulsive Behaviour in Autism Spectrum Disorder

Children with Autism Spectrum Disorder (ASD) have restricted and repetitive behaviours (RRBs) which may be similar to obsessions and compulsions in Obsessive Compulsive Disorder (OCD). These behaviours can be intrusive and interfere in the lives of the child and their family. Preliminary studies have shown success in using adapted Cognitive Behavioural Therapy (CBT) to treat these behaviors in children with high functioning ASD. Using a hypothetical vignette, this thesis attempted to examine procedural knowledge that the children and their parents gained while participating in a CBT treatment that was evaluated in a Randomized Controlled Trial. For both parents and children, there was a significant increase in number of strategies generated from pre to post-treatment. Further, children in the experimental group generated significantly more strategies than the treatment as usual (TAU) group post-intervention. There was no significant correlation between number of strategies generated and the child’s treatment success, age, or IQ.

Éthéréalisation : amorces d'une contre-histoire

Cette thèse est une enquête épistémologique qui s’interroge sur la persistance de « l’éther » dans le champ de la technologie. De façon générale, le mot « éther » évoque un modèle conceptuel de la physique pré-einsteinienne, celui d’un milieu invisible permettant la propagation de la lumière et des ondes électromagnétiques. Or, ce n’est là qu’une des figures de l’éther. Dans plusieurs mythologies et cosmogonies anciennes, le nom « éther » désignait le feu originel contenu dans les plus hautes régions célestes. Aristote nommait « éther », par exemple, le « cinquième être », ou « cinquième élément ». La chimie a aussi sa propre figure de l’éther où il donne son nom à un composé chimique, le C4H10O, qui a été utilisé comme premier anesthésiant général à la fin du XIXe siècle. L’apparition soutenue dans l’histoire de ces figures disparates de l’éther, qui a priori ne semblent pas entretenir de relation entre elles, est pour nous la marque de la persistance de l’éther. Nous défendons ici l’argument selon lequel cette persistance ne se résume pas à la constance de l’attribution d’un mot ou d’un nom à différents phénomènes dans l’histoire, mais à l’actualisation d’une même signature, éthérogène. À l’invitation d’Agamben et en nous inspirant des travaux de Nietzsche et Foucault sur l’histoire-généalogie et ceux de Derrida sur la déconstruction, notre thèse amorce une enquête historique motivée par un approfondissement d’une telle théorisation de la signature. Pour y parvenir, nous proposons de placer l’éther, ou plutôt la signature-éther, au cœur de différentes enquêtes historiques préoccupées par le problème de la technologie. En abordant sous cet angle des enjeux disparates – la légitimation des savoirs narratifs, la suspension des sens, la pseudoscience et la magie, les révolutions de l’information, l’obsession pour le sans-fil, l’économie du corps, la virtualisation de la communication, etc. –, nous proposons dans cette thèse autant d’amorces pour une histoire autre, une contre-histoire.

Vers un cinéma de l'absurde : les films de Roman Polanski

La notion de l'absurde a pris dans la pensée et le langage courant un très grand nombre de significations, parfois très éloignées les unes par rapport aux autres. Il est arrivé à au moins deux reprises que le terme « absurde » soit entendu dans le sens d'un courant : dans la philosophie absurde théorisée par Albert Camus en 1942, et dans le Théâtre de l'absurde (Beckett, Ionesco, etc.), qui lui a connu son apogée dans les années cinquante. Ces deux mouvements pourraient être envisagés comme l'expression d'un seul et même courant, l'absurde, qui prend ses racines dans une Europe ébranlée par les horreurs de la guerre et l'affaissement de la religion chrétienne. Pour les contemporains, l'hostilité et le désordre de l'univers, de même que la solitude irrémédiable de l'individu apparaissent comme des vérités à la fois douloureuses et difficile à ignorer. Roman Polanski (1933-), cinéaste à la fois prolifique et éclectique, ouvre à l'absurde de nouveaux horizons, ceux du septième art. L'analyse de son oeuvre (et des éléments autobiographiques qui la sous-tendent parfois) met à jour d'indéniables parentés avec les figures-clés de l'absurde que sont Camus, Kafka, Nietzsche et les dramaturges européens de l'après-guerre. Ces parentés se repèrent tout autant dans les thématiques récurrentes de ses films que dans leurs obsessions formelles.

Mort et renaissances de l’écrivain maudit : lectures de l’œuvre et de la figure d’Hubert Aquin dans l’essai québécois contemporain

Le présent article s’attache à deux des modes de lecture de l’oeuvre aquinienne qui traversent la critique et l’essai québécois contemporains. La lecture biographique, plus volontiers mythifiante, de certains essayistes et biographes aquiniens permettra, d’une part, de réfléchir à la fascination qu’exerce encore aujourd’hui le sacrifice d’Aquin sur ses lecteurs contemporains. D’autre part, il s’agira de mieux cerner l’inscription de l’oeuvre aquinienne dans les dossiers que la revue « Liberté » a fait paraître entre 2006 et 2012. En réactualisant la dimension politique de l’oeuvre d’Aquin, les auteurs de la revue réfléchissent à la fois sur la quasi-disparition de l’engagement politique dans la sphère culturelle et sur le décentrement de la parole littéraire à l’époque contemporaine. D’un point de vue comme de l’autre, Aquin et son oeuvre méritent d’être relus, d’être tirés de la bibliothèque ou du tombeau afin de répondre, ne serait-ce que par la négative, aux angoisses et aux obsessions des contemporains. Nous entendons en somme dépasser certaines idées reçues sur la construction des figures auctoriales, lesquelles viseraient selon certains auteurs à « simplifier [l’oeuvre] pour [la] rendre comestible ». Malgré ses limites évidentes, le mythe offre à l’oeuvre une possible survie dans le concert des médias contemporains et permet de saisir les enjeux d’une certaine représentation, historique sans doute, de la littérature québécoise.

Joan Miró : una lectura filosófica a través de 'La Masia'.

Se presenta un estudio hermenéutico sobre la obra de Joan Miró. La obra mironiana posibilita establecer algunas relaciones con la obra esotérica de 'El Bosco' y con la mística obra de Kandisky. El estudio tienta desvelar las fuentes místico-semitas, cuyas verdades dirigieron la vida y el quehacer creativo de Miró, siempre movido por una responsabilidad ética. Esta lectura conjuga conocimientos sobre la teoría del arte y el poder creativo del espíritu humano y su capacidad simbólica. El estudio procesa un continuo diálogo entre el arte y la filosofía/psicología, de modo que el saber filosófico fenomenológico o existencial ayuda a entender la obra de Miró, y ésta, a su vez, ilumina la verdad del conocimiento filosófico-existencial. El estudio se divide en cuatro partes. En las tres primeras se pretende desvelar los significados de: los 20 signos de su 'Cortège des obsessions', siempre recurrentes en su obra y cuyo simbolismo cabalístico definiría el espíritu semita-catalán de su autor (I Parte); 'La Masia', como 'metáfora mayor del habitar (existir, en sentido heideggeriano) poético- mí(s)tico del artista' (II Parte) y los 'Autorretratos', cuyo discurso poético 'traduce el acaecer concreto y real del devenir de su ser humano y artístico' (III Parte). Las conclusiones de esta lectura interpretativa son expuestas en la IV Parte del estudio. Se pretende descubrir cuál sería el alcance estético-creador y ético del hecho Miró. Se comentan los pros y contras de la equívoca denominación de Estética para designar la Filosofía del Arte, la Modernidad del lenguaje mironiano (saber estético) y el contenido de su moderna conciencia existencial (saber ético) .

Fifty Years After Angicos : Paulo Freire, Popular Education and the Struggle for a Better World that is Possible

The main thesis of this paper is that Freire’s original experience in Angicos anticipated a grand design for social transformation of educational systems. As such it brought together two key concepts that formulated the basis of his educational system: popular culture as an counter-hegemonic project and popular education, more particularly what was later called citizen schools or public popular education as keystone of his new educational system. I use the term Paulo Freire System to show that his original attempts were not only to challenge pedagogical the prevailing banking education system that was so pervasive in Brazil and Latin American at the time. In challenging the hegemony of banking education, its narrative, theoretical foundations, epistemology and methodology, Freire and his team sought to create a new system that could replace the old one. They saw banking education not only as obsolete in terms of modernization of systems but also oppressive in gnoseological, epistemological and political terms. In the conclusion of this paper I will discuss the twins obsessions of Freire, already present in the Angicos experience and that will stay with him throughout his life: the relationship between democracy, citizenship and education, and education as a postcolonial ethical act of social transformation. I would like to emphasize therefore that the Paulo Freire system, as conceived in the Angicos experience and its aftermath was a much larger and comprehensive system that originally considered, even by his critics.

Entrevista a Francisco Proaño Arandi: se trataba de crear en el lector una sensación de angustia frente a la realidad (Homenaje)

En este diálogo entre el escritor Francisco Proaño Arandi (Premio latinoamericano José María Arguedas, La Habana, 2010) y el lúcido crítico y ensayista Alejandro Moreano, se pasa revista a los años de formación del narrador, la década de los 60, los tzántzicos, la creación de la revista La bufanda del sol, el Frente Cultural en Quito. Proaño, hurgando en la memoria, reconstruye los diversos momentos de lo que fue el debate político y literario de esos años, el peso de la Revolución cubana, las ideas y las propuestas del compromiso del filósofo Jean-Paul Sartre, las luchas anticolonialistas en África, Mayo del 68 y su repercusión en la juventud del mundo, los escritores del boom de la narrativa latinoamericana, su experiencia como diplomático de carrera durante procesos y gobiernos que se sucedieron en el Ecuador en los años 80 y 90. El escritor también da cuenta de lo que es su universo narrativo, las obsesiones, la presencia de una ciudad como Quito en sus diversas novelas y cuentarios, así como la reflexión que a través de sus personajes realiza de las complejas relaciones de la pareja. Diálogo que no solo significó el encuentro de escritores de una misma generación, sino de dos amigos que han sabido compartir la pasión por la escritura de manera vital.

The treatment of mental contamination: a case series

The recommended treatment for obsessive-compulsive disorder (OCD) is cognitive behavior therapy (CBT) incorporating exposure and response prevention (ERP), which is effective for approximately 50% of patients. However, there has been little advance in treatment outcomes since the introduction of ERP in 1979. It has been suggested that some progress can be made in treating contamination obsessions and washing compulsions by addressing feelings of dirtiness and contamination that arise without physical contact with a tangible contaminant. To date, the treatment of these “mental contamination” fears in OCD has not been systematically explored. This paper reports on a case series of 12 participants with OCD who received 10 to 20 sessions of a CBT-based treatment for mental contamination. At the end of treatment, 7 participants no longer met the diagnostic criteria for OCD and mental contamination and these gains were maintained at 6-month follow-up. The clinical implications of these findings are discussed.

The classification of involuntary musical imagery: the case for earworms

Involuntary musical imagery (INMI) is the subject of much recent research interest. INMI covers a number of experience types such as musical obsessions and musical hallucinations. One type of experience has been called earworms, for which the literature provides a number of definitions. In this paper we consider the origins of the term earworm in the German language literature and compare that usage with the English language literature. We consider the published literature on earworms and conclude that there is merit in distinguishing between earworms and other types of types of involuntary musical imagery described in the scientific literature: e.g. musical hallucinations, musical obsessions. We also describe other experiences that can be considered under the term INMI. The aim of future research could be to ascertain similarities and differences between types of INMI with a view to refining the classification scheme proposed here.

Development and validation of the Morphing Fear Questionnaire (MFQ)

Morphing fears (also called transformation obsessions) involve concerns that a person may become contaminated by and acquire undesirable characteristics of others. These symptoms are found in patients with OCD and are thought to be related to mental contamination. Given the high levels of distress and interference morphing fears can cause, a reliable and valid assessment measure is needed. This article describes the development and evaluation of the Morphing Fear Questionnaire (MFQ), a 13-item measure designed to assess for the presence and severity of morphing fears. A sample of 900 participants took part in the research. Of these, 140 reported having a current diagnosis of OCD (SR-OCD) and 760 reported never having had OCD (N-OCD; of whom 24 reported a diagnosis of an anxiety disorder and 23 reported a diagnosis of depression). Factor structure, reliability, and construct and criterion related validity were investigated. Exploratory and confirmatory factor analyses supported a one-factor structure replicable across the N-OCD and SR-OCD group. The MFQ was found to have high internal consistency and good temporal stability, and showed significantly greater associations with convergent measures (assessing obsessive-compulsive symptoms, mental contamination, thought-action fusion and magical thinking) than with divergent measures (assessing depression and anxiety). Moreover, the MFQ successfully discriminated between the SR-OCD sample and the N-OCD group, anxiety disorder sample, and depression sample. These findings suggest that the MFQ has sound psychometric properties and that it can be used to assess morphing fear. Clinical implications are discussed.
