Traumatic stress, dissociation, and limbic irritability in patients with unipolar depression being treated with SSRIs

Recent evidence suggests that stressful experiences may be related to deficits in inhibitory functions and temporo-limbic epileptic-like activity. The latter may produce psychosensory seizure-like symptoms that may also appear in nonepileptic conditions. This study assesses whether the increased presence of the seizure-like symptoms in 113 unipolar depressive patients treated with SSRIs is associated with significantly more severe symptoms of depression, traumatic stress, and dissociation in comparison with 86 healthy controls. Results indicate that seizure-like symptoms in depressive patients have significant association with depression, symptoms of dissociation, and traumatic stress. This association suggests that processess generating seizure-like symptoms may be related to symptoms of depression, traumatic stress, and dissociation.     

Grammatical Gender in Speech Production: Evidence from Czech

Three experiments demonstrate gender congruency effects (i.e., naming times of a picture are faster when the name of the target picture and a distractor noun are gender congruent) in Czech. In the first experiment, subjects named the pictures by producing gender-marked demonstrative pronouns and a noun. In the second and third experiments, subjects produced a gender-marked numeral (marked with a suffix) plus a noun. Two types of such suffixes exist in Czech. Some numerals vary in nominative singular with gender, others do not. The results show significant gender congruency effects in all experiments. They suggest that gender congruency effects can be obtained not only with free, but also with bound morphemes. In the second and third experiment the effect only emerged when the suffix was gender-marked (as opposed to gender-invariant), supporting the view that the gender congruency effect is due to competition at the level of phonological forms rather than at the grammatical level.     

Relational factors of vulnerability and protection for adolescent pregnancy: a cross-sectional comparative study of Portuguese pregnant and nonpregnant adolescents of low socioeconomic status

This study explores multiple relational contexts that promote vulnerability and protection against early pregnancy in a potential risk group of Portuguese adolescents. A comparative analysis was made between two groups of female adolescents of low socioeconomic status: pregnant adolescents (n=57) and adolescents without a history of pregnancy (n=81). Results suggest that several variables belonging to different contexts-family and school and peer relations--are important in the characterization of the two groups. Lower levels of mother's overprotection and father's emotional support, presence of early pregnancy in adolescent's mother, lower level of emotional proximity to peer relations, and higher number of school failures are significantly associated with adolescent pregnancy.     

The Relationships Among Parental Anxiety, Parenting, and Children’s Anxiety: The Mediating Effects of Children’s Cognitive Vulnerabilities

Theoretical models have emphasized the roles played by parental anxiety and behavior in the development of childhood anxiety problems. Little is known regarding the differential impacts of mothers and fathers or regarding the processes that mediate these influences. The present study examines the relationships between maternal and paternal trait anxiety, overprotection, and emotional support on the one hand and anxiety symptoms in children on the other hand. This study also explores the mediating role of children’s cognitive vulnerabilities to anxiety disorders in the relationship between parental variables and children’s anxiety. A sample of 80 children and their parents (fathers and mothers), selected from an initial screening of 905 school-aged children, participated in this study. The results indicate that both parents had unique influences on children’s anxiety symptoms: maternal trait anxiety and paternal overprotection and concern were found to independently and positively contribute to children’s anxiety. Furthermore, children’s interpretative biases mediated the relation between maternal trait anxiety and children’s anxiety symptoms. The results of this study underline the importance of considering both paternal and maternal factors in the development of children’s anxiety problems. These findings also have implications for theoretical models of the etiology of anxiety and for the treatment of these problems in children.     

Kinetic study of static recrystallization in an Fe–Al–O ultra-fine-grained nanocomposite

A nearly abrupt coarsening of grains is observed in a newly developed Fe–Al–O ultra-fine-grained nanocomposite with a significant volume fraction (4%) of alumina nano-precipitates. The microstructure of the alloy was analysed in different states (as-received and annealed) by means of scanning electron microscopy, transmission electron microscopy (TEM) and hardness. The initial grain size 150–200 nm increases up to 50 μm during annealing 1000 °C/8 h and thereafter demonstrates saturation. A linear correlation between volume fraction of coarse grains and hardness was found. It was identified by TEM that alumina nano-precipitates stabilize the dislocation microstructure against recovery very effectively and the grain coarsening is due to fast growth of very few dislocation free grains. Thus, the observed grain coarsening has the attributes of static recrystallization.     

Patterns of Parental Rearing Styles and Child Behaviour Problems among Portuguese School-Aged Children

The majority of studies investigating the effects of parental behaviour on the child’s adjustment have a dimensional approach. We identified the existence of various patterns in parental rearing styles and analysed the relationship between different parenting patterns and behavioural problems in a group of school-aged children. A longitudinal, multi-informant study was conducted. The sample consisted of 519 school-aged children from the Portuguese general population. Parental rearing styles were measured using the EMBU-C, a questionnaire that evaluates children’s perception of parental rearing dimensions. The assessment of child behavioural problems included the evaluation of internalizing and externalizing problems, and data from multiple reporters (parents and teacher). One year later, after a school transition, the adjustment of a sub-sample of 220 children was evaluated again. Cluster analysis identified four types of parental rearing styles: low support, supportive-controller, rejecting-controller, and supportive. In both assessment periods, low support and rejecting-controller parenting patterns showed higher levels of behavioural problems than the supportive and supportive-controller parenting patterns. These patterns show significant differences between them regarding behavioural problems and have a higher predictive value regarding externalizing problems (versus internalizing problems).     

Perceived control and anxiety in Portuguese children

The central role of perceived control in the development of anxiety disorders is proposed by several theoretical models. The main objective of the present study was to examine the relation between perceived control and anxiety in Portuguese school-age children. To accomplish this objective we developed the Portuguese short form of the Anxiety Control Questionnaire for Children (ACQ-C, Weems, 2005; Pereira & Barros, 2010), whose psychometric studies are presented. The sample comprised 238 children, aged 8 to 15 years, from the general population attending Portuguese schools. Children completed measures of perceived control (ACQ-C) and their anxiety (Screen for Child Anxiety Related Emotional Disorders--Revised, SCARED-R). The psychometric studies indicate good psychometric characteristics of the Portuguese ACQ-C short form, in particular a high internal consistency (a = .85) and an adequate temporal stability (r = .60, p = .002). Results show a significant negative association between perceived control and anxiety symptomatology, providing partial support for models that assign a central role to control beliefs in explaining the development of anxiety disorders. These results also suggest the importance of considering the perception of control as a prime target for preventive actions and intervention aimed at reducing anxiety in school aged children.     

Gender processing in first and second languages: the role of noun termination

In 2 picture-naming and 2 grammaticality judgment experiments, the authors explored how the phonological form of a word, especially its termination, affects gender processing by monolinguals and unbalanced bilinguals speaking German. The results of the 2 experiments with native German speakers yielded no significant differences: The reaction times were statistically identical for items from gender typical, ambiguous, and gender atypical groups. The 2 experiments with English bilinguals who had learned German as a second language (L2), however, provided evidence that the L2 word's termination plays a role in L2 gender processing. Participants were fastest when producing gender-marked noun phrases containing a noun with a gender typical termination and slowest when the noun had a gender atypical termination. Analogous results were obtained in the grammaticality judgment experiment. These findings support the assumption that there is interaction between the levels of phonological encoding and grammatical encoding at least in bilingual processing.     

Selection of gender‐incongruent applicants: No gender bias with structured interviews

Research suggests that the use of structured interviews can reduce gender bias in hiring. However, studies have been limited to gender‐neutral professions or laboratory simulations. The current study evaluated two components of the structured interview in a field sample of 691 applicants interviewing for a male‐dominated position of public transit operator. Multilevel modeling results show no significant differences in ratings across applicant gender with this highly structured interview. This relation was found in individual interviewer ratings and consensus panel ratings, as well as irrespective of interviewer gender and interviewer participation in comprehensive versus minimal training in structured interviewing. This study provided a conservative test in a male‐dominated profession to further validate the value of the structured interview for promoting equal hiring practices.
