Methylation of NR3C1 is related to maternal PTSD, parenting stress and maternal medial prefrontal cortical activity in response to child separation among mothers with histories of violence exposure.

Prior research has shown that mothers with Interpersonal violence-related posttraumatic stress disorder (IPV-PTSD) report greater difficulty in parenting their toddlers. Relative to their frequent early exposure to violence and maltreatment, these mothers display dysregulation of their hypothalamic pituitary adrenal axis (HPA-axis), characterized by hypocortisolism. Considering methylation of the promoter region of the glucocorticoid receptor gene NR3C1 as a marker for HPA-axis functioning, with less methylation likely being associated with less circulating cortisol, the present study tested the hypothesis that the degree of methylation of this gene would be negatively correlated with maternal IPV-PTSD severity and parenting stress, and positively correlated with medial prefrontal cortical (mPFC) activity in response to video-stimuli of stressful versus non-stressful mother-child interactions. Following a mental health assessment, 45 mothers and their children (ages 12-42 months) participated in a behavioral protocol involving free-play and laboratory stressors such as mother-child separation. Maternal DNA was extracted from saliva. Interactive behavior was rated on the CARE-Index. During subsequent fMRI scanning, mothers were shown films of free-play and separation drawn from this protocol. Maternal PTSD severity and parenting stress were negatively correlated with the mean percentage of methylation of NR3C1. Maternal mPFC activity in response to video-stimuli of mother-child separation versus play correlated positively to NR3C1 methylation, and negatively to maternal IPV-PTSD and parenting stress. Among interactive behavior variables, child cooperativeness in play was positively correlated with NR3C1 methylation. Thus, the present study is the first published report to our knowledge, suggesting convergence of behavioral, epigenetic, and neuroimaging data that form a psychobiological signature of parenting-risk in the context of early life stress and PTSD.

Máquinas o atmósferas: La estética de la energía en la arquitectura, 1750-2000 = From Machines to Atmospheres: The Aesthetics of Energy in Architecture, 1750-2000

La energía es ya un tema arquitectónico, pero su incorporación al proyecto ha sido hasta ahora fundamentalmente técnica, dando pie a una especie de funcionalismo ecológico cuyo destino es acaso repetir los errores de los viejos funcionalismos en su confianza de encontrar modos ‘objetivos’ de transmutar la energía en forma construida, pero sin que en tal proceso parezca haber hueco para mediaciones de tipo estético. Sin embargo, son precisamente tales mediaciones las que necesitan analizarse para que la adopción de los temas energéticos resulte fructífera en la arquitectura, y asimismo para dar cuenta de otras perspectivas complementarias —filosóficas, científicas, artísticas— que hoy forman el complejo campo semántico de la energía. Partiendo de la fecha de 1750 —que da comienzo simbólicamente al proceso de contaminaciones ‘modernas’ entre la arquitectura y otras disciplinas—, esta tesis analiza los diferentes modos con los que proyectos y edificios han expresado literal y analógicamente ciertos temas o ideales energéticos, demostrando la existencia de una ‘estética de la energía’ en la arquitectura y también de una tradición proyectual e intelectual sostenida en ella. Con este fin, se han seleccionados siete metáforas que vinculan tanto técnica como ideológicamente a la arquitectura con la energía: la metáfora de la máquina, asociada al ideal de movimiento y la autorregulación; las metáforas del arabesco, del cristal y del organismo, afines entre sí en su modo de dar cuenta del principio de la morfogénesis o energía creadora de la naturaleza; la metáfora de la actividad interna de los materiales; la metáfora del gradiente, que expresa la condición térmica y climática de la arquitectura, y, finalmente, la de la atmósfera que, recogiendo los sentidos anteriores, los actualiza en el contexto de la estética contemporánea. La selección de estas siete metáforas se ha llevado a cabo después de un barrido exhaustivo de la bibliografía precedente, y ha estructurado un relato cuyo método combina la perspectiva general —que permite cartografiar las continuidades históricas— con la cercana —que atiende a las problemas específicos de cada tema o metáfora—, complementándolas con una aproximación de sesgo iconográfico cuyo propósito es incidir en los vínculos que se dan entre lo ideológico y lo morfológico. El análisis ha puesto de manifiesto cómo detrás de cada una de estas metáforas se oculta un principio ideológico común —la justificación de la arquitectura desde planteamientos externos procedentes de la ciencia, la filosofía y el arte—, y cómo en cada uno de los casos estudiados las asimilaciones más fructíferas de la energía se han producido según mecanismos de mímesis analógica que inciden más en los procesos que en las formas que estos generan, y que en último término son de índole estética, lo cual constituye un indicio de los métodos de la arquitectura por venir. ABSTRACT Although it is already an architectural theme, the matter of incorporating energy into projects has up to now been mainly technical, giving rise to a kind of ecological functionalism which may be bound to old funcionalist mistakes in hopes of finding “objective” ways of transmuting energy into built forms without aesthetic considerations. However, it is precisely such considerations that need to be analyzed if the adoption of energy issues in architecture is to bear fruit and also to account for other complementary perspectives – philosophical, scientific, artistic – which today form the complex fabric of the energy semantic field. Beginning in 1750 – symbolic start of ‘modern’ contaminations between architecture and other disciplines –, this thesis analyzes the different ways in which projects and buildings have literally and analogically expressed certain subjects or ideals on energy, and demonstrates the existence of an “aesthetics of energy” in architecture, as well as of an intellectual and design tradition based on such aesthetics. For this purpose, seven metaphors are selected to link energy to architecture both technically and ideologically: the machine’s metaphor, associated with the ideal of mouvement and self-regulation; the arabesque, glass and the organism’s metaphors, which account for the morphogenesis principle, i.e. creative energy of nature; the metaphor linked to matter and the ideal of internal activity; the gradient’s metaphor, which expressed the thermal and climatic condition of architecture, and, finally, that of the atmosphere which, collecting the above meanings, updates them in the context of contemporary aesthetics. The selection of these seven metaphors was carried out after a thorough scan of the preceding literature, and has structured a reasoning that combines the overview method – which accounts for historical continuities – with the nearby one – which meets the specifics problems of each theme or metaphor –, both supplemented with an iconographic bias, the purpose of which is to visually express the links existing between the ideological and the morphological. So presented, the analysis shows how, behind each of these metaphors, lies a common ideological principle – the justification of architecture from scientific, philosophical and artistic “external” angles –, and how in each of the studied cases the most successful assimilation of energy were those produced by aesthetic mechanisms of analogical mimesis not focused in forms but in processes that generate them: an indication of the methods of architecture to come.

Eliciting Euphoria Online: The Aesthetics of “ASMR” Video Culture

“Autonomous Sensory Meridian Response” (ASMR) is a term that has emerged online to describe a mysterious tingling sensation that some people experience in response to particular audiovisual and interpersonal “triggers.” Initially coalescing via discussion threads on health forums, ASMR culture quickly began using platforms like YouTube and Reddit to exchange trigger videos. This paper frames the emergence of ASMR video culture as an example of how bodies and algorithms are conspiring to bring into being new cultural forms that can seem literally inexplicable on first encounter. Treating videos as “inputs,” judged not as messages to be understood or interpreted but by their ability to elicit particular affective and somatic “outputs,” ASMR communities cultivate a quasi-cybernetic relationship with the moving image, using video as a vehicle for “feeling out” phenomena that seem to thwart linguistic articulation and rational comprehension.
