Reversible phase transition in vanadium oxide films sputtered on metal substrates

Vanadium oxide films, deposited on aluminium (Al), titanium (Ti) and tantalum (Ta) metal substrates by pulsed RF magnetron sputtering at a working pressure of 1.5 x10^?2 mbar at room temperature are found to display mixed crystalline vanadium oxide phases viz., VO₂, V₂O₃, V₂O₅. The films have been characterized by field-emission scanning electron microscopy, X-ray diffraction, differential scanning calorimetry (DSC) and X-ray photoelectron spectroscopy, and their thermo-optical and electrical properties have been investigated. Studies of the deposited films by DSC have revealed a reversible-phase transition found in the temperature range of 45–49 °C.     

Reluctance to Use Host Social Services by Ethnic Minorities: The Role of Consensual Separation,Threat to Heritage Culture and Misunderstanding of the Host Society Language

The main goal of this study was to examine the relationships between two types of separation orientations, namely forced and consensual separation, and the use of French social service community centers. Participants were two groups of young women, both members of ethnic minorities: Turkish (n?=?42) and North African (n?=?41). The results showed that young Turkish women were more oriented towards consensual separation than young North African women. Preference for a separation strategy was positively associated with both the perception of a threat to heritage culture and difficulties in understanding the language of the social workers. The more participants perceived social workers as a source of threat to their heritage culture and as speaking a language they had difficulty understanding, the less frequently they made use of the services offered at the community centers. Socio-demographic variables such as education level and marital status were found to play a significant role in these findings.     

Cointegration methodology for psychological researchers: An introduction to the analysis of dynamic process systems

Longitudinal data analysis focused on internal characteristics of a single time series has attracted increasing interest among psychologists. The systemic psychological perspective suggests, however, that many long-term phenomena are mutually interconnected, forming a dynamic system. Hence, only multivariate methods can handle such human dynamics appropriately. Unlike the majority of time series methodologies, the cointegration approach allows interdependencies of integrated (i.e., extremely unstable) processes to be modelled. This advantage results from the fact that cointegrated series are connected by stationary long-run equilibrium relationships. Vector error-correction models are frequently used representations of cointegrated systems. They capture both this equilibrium and compensation mechanisms in the case of short-term deviations due to developmental changes. Thus, the past disequilibrium serves as explanatory variable in the dynamic behaviour of current variables. Employing empirical data from cognitive psychology, psychosomatics, and marital interaction research, this paper describes how to apply cointegration methods to dynamic process systems and how to interpret the parameters under investigation from a psychological perspective.     

Child-to-parent violence and its association with exposure to marital violence and parent-to-child violence

The aims of this study were: (a) to examine the relationships between the exposure to different types of family violence (intraparental violence and parent-to-child aggression) and the perpetration of child-to-parent violence (CPV); (b) to analyze sex differences in the relationships specified. The sample comprised 1681 Spanish university students who reported the exposure to different types of family violence during their childhood. Both psychological and physical family violence were analyzed separately. Results showed that both witnessing marital psychological violence and parent-to-child psychological aggression are related to CPV. Furthermore, psychological and physical parent-to-child aggression as well as witnessing physical aggression between parents was associated with physical CPV. Multigroup analyses showed that the relationships among variables were not significantly different as a function of sex. This finding suggests that the relation between exposure to family violence and CPV is similar for men and women.     

Justification of violence as a mediator between exposure to violence and aggressive behavior in children

The aim of this study was to evaluate the mediating role of the justification of violence schema in the relationship between exposure to violence and reactive and proactive aggressive behavior. We differentiated between direct and indirect exposure in four contexts: home, neighborhood, school and TV. A total of 675 children, aged between 8 and 12 years, participated in the study. They answered questionnaires about exposure to violence, justification of violence, and proactive and reactive aggressive behavior in two waves six months apart. The results showed that witnessing violence at home and on TV predicted aggressive behavior, and this relationship was mediated by the justification of violence. Victimization in all contexts predicted aggressive behavior and this relationship was generally mediated by the justification of violence.     

Predicting foreign-accent adaptation in older adults

We investigated comprehension of and adaptation to speech in an unfamiliar accent in older adults. Participants performed a speeded sentence verification task for accented sentences: one group upon auditory-only presentation, and the other group upon audiovisual presentation. Our questions were whether audiovisual presentation would facilitate adaptation to the novel accent, and which cognitive and linguistic measures would predict adaptation. Participants were therefore tested on a range of background tests: hearing acuity, auditory verbal short-term memory, working memory, attention-switching control, selective attention, and vocabulary knowledge. Both auditory-only and audiovisual groups showed improved accuracy and decreasing response times over the course of the experiment, effectively showing accent adaptation. Even though the total amount of improvement was similar for the auditory-only and audiovisual groups, initial rate of adaptation was faster in the audiovisual group. Hearing sensitivity and short-term and working memory measures were associated with efficient processing of the novel accent. Analysis of the relationship between accent comprehension and the background tests revealed furthermore that selective attention and vocabulary size predicted the amount of adaptation over the course of the experiment. These results suggest that vocabulary knowledge and attentional abilities facilitate the attention-shifting strategies proposed to be required for perceptual learning.     

Family hypnotherapy

Abstract

A therapeutic model to help families activate experiential and right hemispheric functioning through hypnosis is presented in detail, together with a clinical illustration. Different situations in which this model is effective are mentioned and one such set of circumstances is described.
