New Beginnings–an experience-based programme addressing the attachment relationship between mothers and their babies in prisons

Data about the quality of attachment between infants and parents in high-risk populations suggests that early intervention may be advantageous for positive developmental outcomes for the child. Mothers in prison represent a high-risk parenting population in terms of both attachment histories and economic and social risk factors. New Beginnings was constructed as a short term, experience-based programme for mothers and infants in the Mother and Baby Units of two UK women's prisons. It is based on the early intervention model developed at the Anna Freud Centre. The programme was piloted in 2004–5, with 27 participating dyads. This paper presents an overview of the pilot stage. Our aim is to introduce the thinking that went into the programme and to present initial observations concerning the effect of the programme. We describe the development of a framework for the programme and its preliminary evaluation using pre- and post-interview protocols concerning the mothers' thoughts and feelings about their babies. We used the Parent Development Interview, for both a qualitative analysis of the major themes in connection to child rearing and quantitative measures of reflective capacity in relation to the child on the part of mother-participants.     

Primal splitting as a basis for emotional and cognitive development in children

This article discusses the importance of good primal splitting as the basis for the child's emotional and cognitive development. A theoretical introduction analyses the possible pathologies of primal splitting, as they were first pointed out by Melanie Klein and then by some post-Kleinian authors, in particular Donald Meltzer. This is followed by some excerpts from the clinical material of the first year of the psychoanalytic psychotherapy of a three-year-old child suffering from eating problems. Starting from the child's play activity, the author tries to identify the splitting problems that underlie the child's view of the world, and to address these with him. The article shows how at times it can be useful to speak also to the child's intelligence, combining the usual analytic work (containment of anxiety and analysis of transference) with the analysis of the child's distortions and cognitive misconceptions. The article also suggests that faulty primal splitting tends to be transmitted from one generation to the next.     

Therapist memory and reverie: implications for the clinical setting

In this work, the author considers reveries to be ‘dream-like-memories’. In the course of a session they appear as proto-memory – the therapist’s early traumatic object relations that are recorded in the unconscious at an almost bodily level (a type of unthought known) and which are resurrected between therapist and patient when a similar traumatic subject arises between them. The therapist’s reveries are recollections in the form of dream-like allusions to his past experience. A clinical vignette from the psychotherapy of a child whose father suffered from PTSD (following a wartime experience in Afghanistan and Iraq) is discussed. Dissociative dynamics were repeated in the therapeutic relationship, in the form of an obsessive game intending to preserve the state in which there was no need to remember what had been unconsciously transmitted to the child: his father’s wartime experience. The projection of the primary elements which had been silenced evoked in the therapist allusions to his unconscious identification with his ancestor’s post-traumatic experiences. These allusions helped in overcoming the dissociated state. The role of memory in child psychotherapists’ receptivity of trauma is revisited.     

风险偏好可以代际传递吗?——来自多学科的证据与元理论思考

心理学、行为与实验经济学、经济社会学等多学科研究逐渐证实了风险偏好的内生性、异质性以及社会性。在探讨经济地位、态度、决策行为等代际传递时,上述学科高度关注和利用风险偏好的上述属性,证实了风险偏好代际传递的有限存在。从风险偏好代际传递的内涵、外延、机制和内容等方面看,风险偏好的研究表现出从横向维度到纵向维度、从因变量到自变量的转向,同时风险偏好代际传递的具体机制和内容也取得了一些重要研究成果。但在研究数量、研究框架、研究方法与内容等方面,风险偏好代际传递还存在一定局限,有待后续研究充实完善。     

Correlation between heat- and deformation-induced crystallization of amorphous Al alloys

Deformation-induced crystallization is correlated with thermal-induced crystallization in alloys with different compositions in a single amorphous alloy system. In Al₈₇Y₆Ni₅Co₂ and Al₈₅Y₈Ni₅Co₂ alloys, which undergo primary crystallization during heating, deformation-induced crystallization of fcc-Al has been observed. In Al₈₃Y₁₀Ni₅Co₂ alloy, which undergoes eutectic-like crystallization, no deformation-induced crystallization was observed. These observations can be explained by the presence or absence of quenched-in nuclei and the work required for the creation of an amorphous/crystalline interface under compressive stress.     

Structural changes induced by low-energy electron irradiation in GaSb

Structural changes in GaSb (001) thin films upon low-energy electron (125?keV) irradiation have been studied by in situ transmission electron microscopy. No structural changes were observed for irradiation at room temperature. However, in a sample irradiated at 473?K domains of {110} variant, rotated 90° from each other, were formed in the matrix. The average diameter of the domains was approximately 18?nm in the sample irradiated to a fluence of 4.8?×?10²⁴?electrons/m². It is considered that the domains are pseudo-{110} planes in the matrix formed by electron-irradiation-induced Shockley partial dislocations.     

Investigations of the optical spectra and EPR g-factors for the tetragonal Ce3+ centers in YPO4 and LuPO4 crystals

The optical spectral band positions and EPR g-factors (g_‖ , g _⊥) for the tetragonal Ce³⁺ centers in YPO₄ and LuPO₄ crystals with the zircon-structure are calculated using a complete diagonalization (of the energy matrix) method (CDM) related to 4f¹ ions in tetragonal symmetry. In this method, the Zeeman interaction term are added to the Hamiltonian in the conventional CDM and so no perturbation calculations are required to obtain the g factors. The crystal-field parameters used in the calculations are obtained from the superposition model in which the local lattice relaxation related to the bonding lengths is considered. The calculated results are in reasonable agreement with the experimental values. It is found that the four observed optical bands for both the systems can be attributed to Ce³⁺ ions in a tetragonal crystal field.     

Atomic configurations of twin boundaries and twinning dislocation in superconductor Y0.6Na0.4Ba2Cu2.7Zn0.3O7− δ

Two types of twin boundaries in superconductor Y_0.6Na_0.4Ba₂Cu_2.7Zn_0.3O_{7? δ} , the cation-centered and oxygen-centered types, and the associated twinning dislocation have been studied by high-resolution electron microscopy. The structure map projected in the [001] direction was obtained from a single image by means of the image deconvolution technique. In this map, all columns of metallic atoms appear as individual black dots, and hence the two types of twin boundaries are distinguished from each other at atomic level. It is seen that the twinning dislocation occurs when the two types of twin boundaries meet each other. The structure model of the twinning dislocation together with the two types of twin boundaries has been derived straightforwardly based on the positions of black dots seen in the deconvoluted image.     

Effects of annealing temperature on structural,optical, and electrical properties of antimony-doped tin oxide thin films

Antimony-doped tin oxide (ATO) films, approximately 320 nm in thickness, have been prepared by electron beam evaporation onto glass substrates. The films were annealed at temperatures between 400°C and 550°C in air and their structure and surface morphologies were observed by X-ray diffraction (XRD) and atomic force microscopy (AFM) after the different annealing treatments. XRD patterns of the ATO thin films as-deposited and annealed at 400°C showed that they were amorphous, but annealing beyond 400°C caused the films to become polycrystalline with tetragonal structure and orientated in the (1 1 0) direction. The grain size in the annealed films, obtained from the XRD analysis, was in the range 146–256 Å and this increased with the annealing temperature. The dislocation density, cell volume and strain were found to decrease gradually with increasing annealing temperature. Photoluminescence spectra revealed an intensive blue/violet peak at 420 nm, which increased gradually in height with annealing. It is suggested that an increase in the population of Sb⁺⁵ ions might be the reason for the enhancement of the blue/violet emission. The optical properties of the films were also investigated in the UV-visible-NIR region (300–1000 nm). The optical constants, namely the refractive index n and the extinction coefficient k in the visible region were calculated. The optical energy band gap, as determined by the dependence of the absorption coefficient on the photon energy at short wavelengths, was found to increase from 3.59 to 3.76 eV with annealing temperature.     

Evolution of a sharp {110} texture in microcrystalline Fe78Si9B13 during magnetic crystallization from the amorphous phase

The effect of magnetic crystallization on texture evolution and control in nanocrystalline materials has been studied using a melt-spun amorphous Fe₇₈Si₉B₁₃ alloy. The magnetic crystallization was conducted at temperatures ranging from 653 to 853?K in a magnetic field up to 6?T. The temperatures used for magnetic crystallization were chosen on the basis of the Curie and crystallization temperatures of the amorphous phase, and the Curie temperature of the crystallized phase. The resultant microstructure was characterized by X-ray diffraction and FE-SEM/EBSP/OIM techniques. It was found that a sharp {110} texture developed when the amorphous precursor was crystallized at 853?K in a magnetic field of 6?T applied in a direction parallel to the ribbon surface.
