Severe maternal psychopathology and infant-mother attachment.

Eighty-two mother-infant dyads, comprising women with psychiatric disorder and individually matched controls, were followed up over the children's 1st year of life. The mothers with mental illness consisted of two subgroups: first, 25 severely mentally ill mothers who had been admitted to a psychiatric unit with their infants; and second, 16 mothers from a community sample meeting research diagnostic criteria for unipolar, nonpsychotic depression. With the exception of six dyads in the in-patient group, observations were made of the mother-infant interaction and the quality of the infant-mother attachment relationship at 12 months. The nature and course of the mothers' illness was also documented. Although few residual symptoms of maternal mental illness were detected at 1 year postpartum, interactional disturbances were evident among the case group dyads. A strong association was revealed between infant-mother attachment quality and maternal diagnosis; a manic episode of illness in the postpartum period was related to security in the attachment relationship, and psychotic or nonpsychotic depression was related to insecurity. Concurrent patterns of mother-infant interaction provided support for this finding

Peer victimization in Dutch school classes of four- to five-year-olds: Contributing factors at the school level

This research was designed to examine how factors within young children's environment (e.g., school factors, neighborhood) contribute to explaining peer victimization. The sample comprised 2,003 children (between 4 and 5 years of age) from 98 classrooms in 23 elementary schools in the Netherlands. Teachers were asked to complete a questionnaire on exposure to victimization for each child. Multilevel analyses revealed that gender and social climate of the school were directly related to victimization. Furthermore, results indicated that peer victimization in boys was less prevalent when they attended smaller schools. In low-SES neighborhoods victimization scores were significantly lower when schools had implemented clear antibullying policies. Finally, variation among school classes appeared to be strongly associated with victimization, even more so than variation among schools. These findings support broadening the focus beyond the individual child at risk. © 2009 by The University of Chicago. All rights reserved

Links between social information processing in middle childhood and involvement in bullying. [IF 0.95]

The aim of this study was to investigate the way in which bullies, victims, bully/victims, and those not involved process social information. A peer nomination measure of bullying and victimization was administered twice over an interval of one year. The sample consisted of 236 (126 girls and 110 boys) children at the beginning of the study (TI) and 242 children one year later (T2) (mean age: 8 years). To test how children responded when provoked, both spontaneously and after prompting, we used provocation scenarios, and to test their attributional interpretations we used ambiguous scenarios. The results showed that children not involved in bullying responded in an assertive way to provocation more often than bullies and victims, but not more than bully/victims. In general, aggressive answers diminished after prompting and irrelevant answers increased. Appealing for the help of an adult or a peer was the strategy most often chosen. When the intent of the perpetrator was ambiguous, bully/ victims attributed more blame, were angrier, and would retaliate more than those not involved. Partly similar results were obtained when stably involved children were compared with those unstably involved. Suggestions for intervention are presented. © 2003 Wiley-Liss, Inc

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Measurement of the cross section for isolated-photon plus jet production in pp collisions at √s=13 TeV using the ATLAS detector

The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti- algorithm with radius parameter and required to have transverse momenta above 100 GeV. Measurements of isolated-photon plus jet cross sections are presented as functions of the leading-photon transverse energy, the leading-jet transverse momentum, the azimuthal angular separation between the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass system. Tree-level plus parton-shower predictions from Sherpa and Pythia as well as next-to-leading-order QCD predictions from Jetphox and Sherpa are compared to the measurements
