The role of postdeployment social factors in linking deployment experiences and current posttraumatic stress disorder symptomatology among male and female veterans

Background and Objectives: The postdeployment social context is likely highly salient in explaining mental health symptoms following deployment. The aim of this study was to examine the role of postdeployment social factors (social support and social reintegration difficulty) in linking deployment-related experiences (warfare exposure, sexual harassment, concerns about relationship disruptions, and deployment social support) and posttraumatic stress disorder (PTSD) symptomatology in male and female veterans.

Design: A survey was administered to 998 potential participants (after accounting for undeliverable mail) who had returned from deployment to Afghanistan or Iraq. Completed surveys were received from 469 veterans, yielding a response rate of 47%.

Methods: Hypotheses were examined using structural equation modeling.

Results: For male and female veterans, deployment factors predicted later PTSD symptoms through postdeployment social support and social reintegration, with lower support and higher social reintegration difficulty both associated with higher PTSD symptomatology. While the final models for women and men indicated similar risk mechanisms, some differences in pathways were observed. Sexual harassment presented more of a risk for women, whereas lower social support was a greater risk factor for men.

Conclusions: Postdeployment social factors appear to represent potentially important targets for interventions aiming to reduce the potential impact of stressful deployment experiences.     

Revised Provisional Diagnostic Profile: 2016

ABSTRACT

In Anna Freud’s and other previous versions of the diagnostic profile, drive theory and the structural model were the central organizing concepts. Though these are retained in the current version, greater emphasis has been made of other conceptual perspectives. In particular, the importance of understanding the impact of the child’s external world and the child’s attachment security; also the central importance of affects, both their recognition and management. These changes are seen in such sections as those on the ego which has been expanded to include a section on play and affects. The developmental line of anxiety and the concept of theory of mind have also been added.     

Using leap motion to investigate the emergence of structure in speech and language

In evolutionary linguistics, experiments using artificial signal spaces are being used to investigate the emergenceof speech structure. These signal spaces need to be continuous, non-discretized spaces from which discrete unitsand patterns can emerge. They need to be dissimilar from—but comparable with—the vocal tract, in order tominimize interference from pre-existing linguistic knowledge, while informing us about language. This is a hardbalance to strike. This article outlines a new approach that uses the Leap Motion, an infrared controller that canconvert manual movement in 3d space into sound. The signal space using this approach is more flexible than signalspaces in previous attempts. Further, output data using this approach is simpler to arrange and analyze. Theexperimental interface was built using free, and mostly open- source libraries in Python. We provide our sourcecode for other researchers as open source.     

BDNF-induced synaptic delivery of AMPAR subunits is differentially dependent on NMDA receptors and requires ERK

Previous studies using an in vitro model of eyeblink classical conditioning in turtles suggest that increased numbers of synaptic AMPARs supports the acquisition and expression of conditioned responses (CRs). Brain-derived neurotrophic factor (BDNF) and its associated receptor tyrosine kinase, TrkB, is also required for acquisition of CRs. Bath application of BDNF alone induces synaptic delivery of GluR1- and GluR4-containing AMPARs that is blocked by coapplication of the receptor tyrosine kinase inhibitor K252a. The molecular mechanisms involved in BDNF-induced AMPAR trafficking remain largely unknown. The aim of this study was to determine whether BDNF-induced synaptic AMPAR incorporation utilizes similar cellular mechanisms as AMPAR trafficking that occurs during in vitro classical conditioning. Using pharmacological blockade and confocal imaging, the results show that synaptic delivery of GluR1 subunits during conditioning or BDNF application does not require activity of NMDARs but is mediated by extracellular signal-regulated kinase (ERK). In contrast, synaptic delivery of GluR4-containing AMPARs during both conditioning and BDNF application is NMDAR- as well as ERK-dependent. These findings indicate that BDNF application mimics AMPAR trafficking observed during conditioning by activation of some of the same intracellular signaling pathways and suggest that BDNF is a key signal transduction element in postsynaptic events that mediate conditioning.     

Structure and continuity of intellectual development in early childhood

We evaluated over 200 participants semiannually from 12 to 48 months of age on measures of intellectual (Bayley Scales, Stanford–Binet Scale) and verbal (MacArthur–Bates Inventory, Peabody Picture Vocabulary Test) status. Structural equation modeling and hierarchical linear (growth curve) analyses were applied to address the nature of development and individual differences during this time. Structural analyses showed a strong and robust simplex model from infancy to the preschool period, with no evidence of qualitative reorganizations or discontinuities. Growth-curve modeling revealed significant associations between level factors across the early and later measures of cognition, providing further evidence of continuity; the growth trajectory from the Bayley through 24 months predicted growth in a nonverbal factor, but not in a verbal factor. Altogether, the findings reveal continuous and stable development in intellectual function from late infancy through the preschool years. Additionally, the high level of continuity demonstrated across these ages was observed to be largely independent of growth in vocabulary.     

Adolescents’ preferences for sexual dimorphism are influenced by relative exposure to male and female faces

Exposure to a particular population of faces can increase ratings of the normality and attractiveness of similar-looking faces. Such exposure can also refine the perceived boundaries of that face population, such that other faces are more readily perceived as dissimilar. We predicted that relatively less exposure to opposite-sex faces, as experienced by children at single-sex compared with mixed-sex schools, would decrease ratings of the attractiveness of sexual dimorphism in opposite-sex faces (that is, boys at single-sex schools would show a decreased preference for feminised faces, and girls at single-sex schools would show a decreased preference for masculinised faces). Consistent with this prediction, girls at single-sex compared with mixed-sex schools demonstrated significantly stronger preferences for facial femininity in both male and female faces. Boys at single-sex compared with mixed-sex schools demonstrated marginally stronger preferences for facial masculinity in male faces, but did not differ in their ratings of female faces. These effects were attenuated among some single-sex school pupils by the presence of adolescent opposite-sex siblings. These data add to the evidence that long-term exposure to a particular face population can influence judgements of other faces, and contribute to our understanding of the factors leading to individual differences in face preferences.     

Should President Clinton be prosecuted for perjury? The effects of preference for consistency, self-esteem, and political party affiliation

Conducted in the fall of 2000, this study investigates personality and social variables that should predict attitudes regarding the desirability of prosecuting President Clinton for perjury following the expiration of his term (in January of 2001). Prosecution was favored by High Preference for Consistency (PFC) more than Low PFC individuals, by High Self-Esteem more than Low Self-Esteem individuals, and by Republicans more than Democrats. In addition, PFC and Party Affiliation interacted: High PFCs wanted Clinton prosecuted regardless of Party Affiliation, but Low PFCs desired prosecution strongly only if they were Republicans. Overall, the results are consistent with the general self-theory principle that human beings tend to adopt attitudes and positions that restore, maintain, or enhance self-esteem.     

Cross-National Comparison of Attitudes Toward Fathers' and Mothers' Participation in Household Tasks and Childcare

The purpose of this study was to explore attitudes toward the division of fathers' and mothers' participation in childcare/household tasks through a multilevel modeling approach. Data from the Euro-barometer surveys, including over 10,000 respondents from 13 European countries, were used. Respondents' attitudes were related to several individual-and macro-level factors. At the individual level (based on a separate regression equation for each country), it was found that respondents were most likely to hold egalitarian attitudes toward household work and childcare when they were younger, female, and politically liberal. At the macro level, countries' United Nations ratings on women's empowerment, Gross National Product, and cultural individualism were related to egalitarian attitudes. Study implications, strengths and weaknesses, and suggestions for future research are discussed.     

Psychoanalysis, Parents, and God: Julia Kristeva on Subjectivity and the Imaginary Father

This article examines Julia Kristeva's theories of language, subjectivity, and faith. Kristeva's perspectives contain surprising resources for feminist theologians concerned about gender-inclusive language for God. Her concept of the Imaginary father offers a way to understand how God-language functions for person in relation to their subjectivity. Such an understanding can assist feminist thinkers to move beyond contemporary stalemates in theological appropriations of object relations theory, toward new feminist perspectives on subjectivity and new practices for transforming gendered language about God.     

Family meaning of self-starvation: themes discerned in family treatment in Hong Kong

This study aims to identify themes from the treatment of Chinese families with an adolescent or an adult member suffering from anorexia nervosa (AN), through a multiple case study. This study reveals that self-starvation may be regarded as a cultural metaphor. Four major themes emerged at the family level: self-starvation as an expression of love and control, coalition of the AN daughter with the mother, family loyalty, and the powerlessness and helplessness of the mother. The themes identified are narrative accounts of the Hong Kong Chinese families, rather than causal explanations proposed by Western literature. The emerging themes are believed to be constructed and legitimized by traditional Chinese cultural values, with females being subordinated to and dependent on males and the self being subjugated to or sacrificed for the collective. Treatment implications are discussed.
