Displacement trauma: complex states of personal,collective and intergenerational fragmentation and their intergenerational transmission

Originally presented at the Journal’s one day conference entitled ‘Displacement: Contemporary Traumatic Experience’ held in London in November 2019, this paper expands on the author’s theory of the implicit psychological organizing gestalt, an associated pattern of psychic functions which operate in an integrated way to simultaneously structure and organize our experience of self-cohesion and self-continuity. The gestalt, which implicitly links the formation of psychic skin, body image, cultural skin and both personal and cultural identity with place, functions as an emergent non-conscious permanent presence or background ‘constant’. It develops over time and emerges out of embodied emotional experiencing with the total environment – both human and non-human. The author argues that it is the rupture of this gestalt and the disorganizing consequences of its loss which underlies the experience of displacement trauma. If disruptions in the formation of the gestalt and/or its later rupture remain unrecognized and unrepresented then the absence creates a void which can be intergenerationally transmitted. Case material is presented which describes this and which highlights the ways in which the gestalt can contribute to our understanding of collective displacement anxiety, cultural trauma and cultural complexes.     

老子之道及其创生因子探究

"道"是老子哲学体系中的核心,老子不仅提出虚空的道是宇宙的本体,是无法用语言来描述的,而且说明道是混成之物,即道是有精妙的内部结构属性的,并从不同的侧面说明了认识"道"是混成之物的路径。道是由无限创生因子混融而成的系统,宇宙在创生及万物演化的过程中,道或无限的创生因子始终起着根本性的作用,即宇宙间的一切事物现象都是道所为。道是由创生因子混融而成的思想观点,可为现代宇宙论的发展提供新的思维维度,为科学探索真空世界的奥秘提供新的研究途径,推进现代宇宙学的进步。     

RICOEUR'S PHILOSOPHY AND ITS IMPLICATIONS FOR PSYCHOANALYSIS

In differentiation of early and mature shame, the phenomenological content of shame changes with the development of a stable self-state. In this hypothesis, early shame refers to a person's dependence upon mirroring himself and in being mirrored by an outer object, while mature shame refers to introspection and self-reflection. From a developmental psychological point of view, the connection between self-development and mirroring is expounded. Mirroring is defined as a psychic dialectic process between the inner psychic reality and the outer reality. Early shame is connected to dyadic mirroring, which refers to attachment and empathy. Mature shame is connected to triadic mirroring, which refers to separation and reflection. Early shame emerges from discrepancies between the infant's expectations of a complementary affective response and the mother's response, and is defined as an early marker of differences in the mother/infant unit. It is argued that early shame in smaller ‘doses’ has a regulating function on self-development by maintaining the psychic dialectic process, while in larger ‘doses’, it has a disturbing effect on the self-development, resulting in pathological shame. In the therapeutic process, early shame appears as shame scenarios illustrated in the text by a clinical vignette.     

Effect of elasto-plastic compatibility of grains on void-initiation criteria in low-carbon steel

The present study provides evidence for the role of ferrite-grain-size distributions on the occurrence of void initiation in a low-carbon steel. Various thermomechanical treatments were undertaken to create ultrafine, bimodal and coarse distributions of ferrite grain sizes. A two-parameter characterisation of probable void initiation sites is proposed, namely an elastic modulus difference and a difference in Schmid factor of the grains surrounding the void. All microstructures were categorised based on the ability to facilitate or resist void nucleation. For coarse grains, the elastic modulus and the Schmid factor differences are the highest, while they are intermediate for ultrafine grains and the lowest for the bimodal microstructure.     

Fractals and scaling in fracture induced by microcrack coalescence

A numerical model is proposed to simulate fracture induced by the coalescence of numerous microcracks, in which the condition for coalescence between two randomly nucleated microcracks is determined in terms of a load-sharing principle. The results of the simulation show that, as the number density of nucleated microcracks increases, stochastic coalescence first occurs followed by a small fluctuation, and finally a newly nucleated microcrack triggers a cascade coalescence of microcracks resulting in catastrophic failure. The fracture profiles exhibit self-affine fractal characteristics with a universal roughness exponent, but the critical damage threshold is sensitive to details of the model. The spatiotemporal distribution of nucleated microcracks in the vicinity of critical failure follows a power-law behaviour, which implies that the microcrack system may evolve to a critical state.     

An atomistic modelling and statistical analysis study of crack–void interaction in Aluminum

The interaction between a brittle crack and pre-existing void in front of the crack tip was studied in the realm of molecular dynamics simulations at the nanoscale in face centred cubic Al within the framework of embedded-atom method. The results provide corroborative evidence of the fact that presence of a void in front of a running crack deters further crack growth. By performing an extensive series of simulations with different void sizes and crack-void distances coupled with statistical analysis, it has been found that (1) major role of voids is to decrease the fracture stress with increasing void size, in addition to slight increase in strain at which the crack growth occurs and the consequent strain to fracture, (2) fracture stress for a constant void size follows a sinusoidal distribution by varying the crack-void distance and (3) it is the void size that is most crucial in dictating the fracture properties of the material, rather than the void placement.     

Sitting through the emptiness

This article explores clinical encounters with experiences of the ‘empty ego’ which arise from early relational trauma. The ego’s emptiness is held in repetitious complexes and arises out of affectively charged experiences between self and other which remain split-off from awareness. This kind of consciousness is viewed as dualistic, separating non-dual subjectivity from its dualistic objects of consciousness. In contrast, what I am calling healing void states of non-dualistic consciousness, when admitted to awareness, allow the individual to dis-identify from the traumatizing representations of self and other through an experience of non-duality. In contrast to an objectified, dualistic emptiness of the ego, healing void states come about in moments of non-dual, unified consciousness. These states occur in the ego-Self relationship by linking the ego’s dualistic awareness in chronic subject/object splits to ones of non-dual pure consciousness. The healing void state is always incipiently present and potentially able to bridge the ego-Self connection in bogged-down treatment. The paper explores potential integrations with non-dual models of consciousness such as Vedantic and Kashmir Shaivism, among other mystical traditions. A combined Vedantic-Jungian understanding can provide a transcendent bridge that integrates Eastern concepts of non-duality in treating emptiness.     

Abnormally high residual dislocation density in pure aluminum after Al/Ti/Al laminate annealing for seven days

We report an abnormally high residual dislocation density in aluminium in an Al/Ti/Al laminate annealed at 873 K for seven days. The residual dislocation density reaches 7.5 × 10¹⁴ m^?2, higher than that in aluminum after severe plastic deformation processes such as accumulative roll bonding and high-pressure torsion. It is proposed that the high residual dislocation density may result from obstruction of the movement of TiAl₃ nanoparticles by the grain boundary and Ti atoms conglomerating at vacancies distributed in the aluminium matrix at a high temperature for a sufficient time to allow a relatively stable crystal.     

Intermetallic compound identification and Kirkendall void formation in eutectic SnIn/Cu solder joint during solid-state aging

Microstructural investigations were performed on the interfacial reactions between eutectic SnIn solder and Cu substrate during reflowing at 433?K and solid-state aging at 373?K. Cu₂(In,Sn) was identified as the only intermetallic compound (IMC) at the interface, which consists of two sublayers with different morphology, a fine-grained sublayer at the Cu side and a coarse-grained sublayer at the solder side. During solid-state aging, voids were found between these two Cu₂(In,Sn) sublayers but not at the substrate interface, which is also attributed to the Kirkendall effect considering the different diffusion fluxes of Sn or In and Cu atoms in different sublayers.     

Influence of the restored work-hardening rate on ductility studied by X-ray computed tomography

Abstract

Void growth and coalescence in a model material containing an artificial three-dimensional void array (the estimated local void volume fraction was 1.1%) were investigated by X-ray computed tomography (=XCT). The initially tapered cylindrical voids became elongated along the principal straining direction by some amount of tensile plastic deformation, and then the work-hardening capacity in the intervoid matrix was restored by an intermediate annealing. The annealed model material was pulled in tension all the way up to fracture to see if the existing void coalescence models can predict the void coalescence strain.
