The parent?infant dyad and the construction of the subjective self

Developmental psychology and psychopathology has in the past been more concerned with the quality of self-representation than with the development of the subjective agency which underpins our experience of feeling, thought and action, a key function of mentalisation. This review begins by contrasting a Cartesian view of pre-wired introspective subjectivity with a constructionist model based on the assumption of an innate contingency detector which orients the infant towards aspects of the social world that react congruently and in a specifically cued informative manner that expresses and facilitates the assimilation of cultural knowledge. Research on the neural mechanisms associated with mentalisation and social influences on its development are reviewed. It is suggested that the infant focuses on the attachment figure as a source of reliable information about the world. The construction of the sense of a subjective self is then an aspect of acquiring knowledge about the world through the caregiver's pedagogical communicative displays which in this context focuses on the child's thoughts and feelings. We argue that a number of possible mechanisms, including complementary activation of attachment and mentalisation, the disruptive effect of maltreatment on parent-child communication, the biobehavioural overlap of cues for learning and cues for attachment, may have a role in ensuring that the quality of relationship with the caregiver influences the development of the child's experience of thoughts and feelings

Gluons and the quark sea at high energies: distributions, polarization, tomography

This report is based on a ten-week program on "Gluons and the quark sea at high-energies", which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The principal aim of the program was to develop and sharpen the science case for an Electron-Ion Collider (EIC), a facility that will be able to collide electrons and positrons with polarized protons and with light to heavy nuclei at high energies, offering unprecedented possibilities for in-depth studies of quantum chromodynamics. This report is organized around four major themes: i) the spin and flavor structure of the proton, ii) three-dimensional structure of nucleons and nuclei in momentum and configuration space, iii) QCD matter in nuclei, and iv) Electroweak physics and the search for physics beyond the Standard Model. Beginning with an executive summary, the report contains tables of key measurements, chapter overviews for each of the major scientific themes, and detailed individual contributions on various aspects of the scientific opportunities presented by an EIC.Comment: 547 pages, A report on the joint BNL/INT/Jlab program on the science case for an Electron-Ion Collider, September 13 to November 19, 2010, Institute for Nuclear Theory, Seattle; v2 with minor changes, matches printed versio

The influence of social support, conflict, and stressful life events on PTSD, depression, and anxiety symptom severity in U.S. army female veterans

IntroductionThere have been prevailing gender differences in negative mental health outcomes for female U.S. veterans returning from combat deployments. Research has validated the importance of post-deployment social support in mitigating the effects of these experiences on mental health; however, the influence of conflict within the social network has not been thoroughly explored.Aims(1)Examine the relationships between social support, conflict, and stressful life events to PTSD, depression, and anxiety symptom severity in female veterans 6–12 months after deployment.(2)Determine whether the absence of social support or the presence of social conflict is more influential in the severity of these symptoms.MethodsDescriptive, correlationalResultsThere were significant positive bivariate correlations (p &lt; .01) between conflict and stressful life events and significant negative bivariate correlations (p &lt; .01) between social support and each of the three outcome variables: PTSD, depression, and anxiety symptoms. Hierarchical linear regression showed that co-morbid depression, greater post-deployment stressful life events, and greater conflict within the social network best explained the presence of greater PTSD symptom severity. Stressful life events did not contribute to greater anxiety symptom severity; however, symptom severity was affected by the absence of social support. In contrast, greater depression symptom severity was best explained by the presence of co-morbid PTSD symptoms and the absence of social support.ConclusionsTreatment programs for PTSD and anxiety in female veterans’ post-deployment must assess and address sources of intrapersonal conflict within their social networks. Family therapy may be integral to treatment success.</jats:sec
