Peer-Victimization and Mental Health Problems in Adolescents: Are Parental and School Support Protective?

The aim of this study was to investigate the frequency and effects of peer-victimization on mental health problems among adolescents. Parental and school support were assumed as protective factors that might interact with one another in acting as buffers for adolescents against the risk of peer-victimization. Besides these protective factors, age and gender were additionally considered as moderating factors. The Social and Health Assessment survey was conducted among 986 students aged 11–18 years in order to assess peer-victimization, risk and protective factors and mental health problems. For mental health problems, the Strengths and Difficulties Questionnaire (SDQ) was used. Effects of peer-victimization on mental health problems were additionally compared with normative SDQ data in order to obtain information about clinically relevant psychopathology in our study sample. Results of this study show that peer-victimization carries a serious risk for mental health problems in adolescents. School support is effective in both male and female adolescents by acting as a buffer against the effect of victimization, and school support gains increasing importance in more senior students. Parental support seems to be protective against maladjustment, especially in peer-victimized girls entering secondary school. Since the effect of peer-victimization can be reduced by parental and school support, educational interventions are of great importance in cases of peer-victimization

On the link between perceived parental rearing behaviors and self-conscious emotions in adolescents

Contains fulltext : 170400.pdf (publisher's version ) (Open Access)This study examined relationships between the self-conscious emotions of guilt and shame in both clinical (N = 104) and non-clinical (N = 477) (young) adolescents aged 11-18 years, who completed a questionnaire to assess perceived parental rearing behaviors (EMBU-C) and a scenario-based instrument to measure proneness to guilt and shame (SCEMAS). Results indicated that parental rearing dimensions were positively related to self-conscious emotions. Regarding the non-clinical sample, both favourable (emotional warmth) and unfavourable (rejection) paternal and maternal rearing dimensions were significant correlates of guilt- and shame-proneness. The results for the clinical sample were less conclusive: only maternal emotional warmth and rejection were found to be significantly associated with guilt and shame. Interestingly, no associations between any of the paternal rearing dimensions and self-conscious emotions emerged. Taken together, these results are in keeping with the notion that parental rearing factors are involved in the development of both adaptive and maladaptive self-conscious emotions in adolescents.10 p

Experimental Evaluation of ILC Applied to a Six Degrees-of-Freedom Industrial Robot

Experimental evaluation of an Iterative Learning Control (ILC) algorithm is presented. The ILC algorithm is applied to all motors of a large size commercial six degrees-of-freedom industrial robot in order to minimise the error measured on the motor angles. The performance of the algorithm is evaluated with respect to the operating point of the robot, the programmed tool velocity, and the design variables of the ILC algorithm. The chosen movements are intended to represent typical paths in a laser cutting application. Even though a fairly simple ILC algorithm is applied, the error reduction is substantial after only five iterations and the algorithm shows good robustness properties
