Aggression and the psychic self

In this paper we explore the idea of aggression as a defence against threats to the psychological self. This aspect of the self allows reflection about people in psychological terms and develops, in the first three years of life, through appreciation of mental states in the other. When the object is unpredictable or hostile, recognition of this is painful to the child, and his reflective function will not be adequately established. The defences of aggression or avoidance will be invoked very frequently. In time, aggression may become an organising influence in the construction of the self; pathological destructiveness then takes the place of emotional relatedness and concern for the other. Psychoanalytic treatment no longer works primarily by addressing conflict. Instead, particularly through interpretations of transference and countertransference, the analyst recreates an intersubjective process which enhances the patient's reflective self, this time in the safety of a benign relationship.     

Spatial heterogeneity of personal exposure to airborne metals in French urban areas

The spatial distribution of urban population exposures to ambient air particles was investigated as part of the Genotox'ER study conducted in four metropolitan areas (Grenoble, Paris, Rouen and Strasbourg) in France. In each city, 60 to 90 non-smoking adult and children volunteers were selected. Subjects lived in three different urban sectors: one highly exposed to traffic emissions, one influenced by local industrial sources, and a background urban environment. The Harvard Chempass multi-pollutant personal sampler was used to sample PM10 and PM2.5 particles during 48 h during two different seasons ('hot' and 'cold'). The elemental composition of the filters was analysed by Particle-Induced X-ray Emission (PIXE). Sixteen elements were found to be over the method detection limits: Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn and Pb. The relative concentrations of elements of crustal origin (Si, Al, Ca) were higher in the coarse fraction of PM10 filters, while elements associated with combustion processes (traffic emissions or industrial combustion) presented higher relative concentrations in the PM2.5 fraction (S, Ni, V, Pb). Spatial heterogeneity of elemental exposures by urban sector is substantial for some metals of health concern, with 20% to 90% greater exposure values, on average, in the traffic proximity or industrial sectors, compared to the background sector, for Fe, Zn, Cu, V and Cr. This spatial heterogeneity should not be overlooked in epidemiological or risk assessment studies.     

溶胶-凝胶法制备惯性约束聚变靶材料研究

本文主要介绍用sol-gel法制备具有纳米结构的SiO2、TiO2和ZrO2材料.这些材料的孔洞率和比表面积甚高(孔洞率为80%～99.8%,比表面积为1 000 m2/g),孔洞尺寸和体积密度极小(典型的孔洞尺寸为1～100 nm,最低体积密度为10 kg/m3);折射率n在1.1～1.9范围内可调,并在相当大的范围具有很好的光谱选择性;材料的耐温特性良好,可耐温500 ℃以上.这些结构和性能特点有可能为惯性约束聚变研究扩展了靶材料选择的范围.此外,就制备过程中前驱体的选择、水解度和催化剂的影响、凝胶过程和后处理工艺对材料结构特性的影响进行了讨论.

Attachment and reflective function: their role in self-organization

The paper traces the relationship between attachment processes and the development of the capacity to envision mental states in self and others. We suggest that the ability to mentalize, to represent behavior in terms of mental states, or to have "a theory of mind" is a key determinant of self-organization which is acquired in the context of the child's early social relationships. Evidence for an association between the quality of attachment relationship and reflective function in the parent and the child is reviewed and interpreted in the context of current models of theory of mind development. A model of the development of self-organization is proposed which has at its core the caregiver's ability to communicate understanding of the child's intentional stance. The implications of the model for pathological self-development are explored, with specific reference to the consequences of maltreatment.     

Outcome research on the psychosocial treatment of personality disorders

This brief overview of outcome research on psychosocial treatment of personality disorders first examines difficulties in using existing classifications of abnormal personality. A summary is offered of uncontrolled investigations of the treatment of personality disorders, a few controlled studies, and literature on the impact of comorbid personality disorder on treatment of Axis I symptomatology. The conclusions take into account the particular challenges of these disorders in the current health care context.     

Mentalization in adult attachment narratives: Reflective functioning, mental states, and affect elaboration compared.

Relationships between three measures of mentalization (reflective function, mental states, and verbal elaboration of affect), attachment status, and the severity of axis I and axis II pathology were examined. Seventy-three adults, both ex-psychiatric patients and nonclinical volunteers were administered the Adult Attachment Interview (AAI). Comparisons between the three measures indicate that they share some aspect of a core mentalization process and that each illuminates a specific component. Reflective function was the only predictor of attachment status. The number of axis I diagnoses is partly explained by attachment insecurity, but the capacity to generate high-level defensive mental states as well as increments in verbal affect elaboration further contribute to the model. Finally, increments in affect elaboration, as well as augmentations in high-level defensive activity and reflective function are all associated with decreases in the number of axis II diagnoses, over and above the contribution of attachment status and axis I pathology.

Multi-scale sparse feature point correspondence by graph cuts

This paper presents a global stereo sparse matching technique based on graph cut theory to obtain accurate correspondence of stereo point pair in vision measurement applications.First, in order to obtain accurate location of feature points, a new multi-scale corner detection algorithm is proposed where wavelet coefficients are used to determine feature points by calculating an auto-correlation matrix.A sparse graph is constructed based on the feature points according to the graph cut theory.Then, the featur...
