Predicting parenting stress: children's behavioural problems and parents' coping

This study examined the effects of child characteristics and parent coping practices on parenting stress, based on a sample of parents of 64 boys with behavioural problems and a comparison group with parents of 128 boys. All parents completed questionnaires about stress, length of education, child characteristics, social support, sense of coherence and coping practices, in addition to interviews in their home about daily activities and relations with the child. A hierarchical regression model for predicting parenting stress was tested, and the results showed that having a child with behavioural problems predicted 57% of the variance in parenting stress. Social support and parental resources and strategies added to the prediction of parenting stress after controlling for family demographics and child characteristics. The parents in the clinical group (with boys referred to psychiatric units) were more often single parents with lower education, more often unemployed, less content with social support, and had lower scores on comprehensibility. These parents were significantly more stressed than parents in the comparison group. All these risk factors might be barriers against establishing a protective frame around a child. These parents, with a difficult child‐rearing situation, who perceived less support and had fewer material benefits, seemed to be more vulnerable. Copyright © 2010 John Wiley & Sons, Ltd.     

Problematic video game use: estimated prevalence and associations with mental and physical health

A nationwide survey was conducted to investigate the prevalence of video game addiction and problematic video game use and their association with physical and mental health. An initial sample comprising 2,500 individuals was randomly selected from the Norwegian National Registry. A total of 816 (34.0 percent) individuals completed and returned the questionnaire. The majority (56.3 percent) of respondents used video games on a regular basis. The prevalence of video game addiction was estimated to be 0.6 percent, with problematic use of video games reported by 4.1 percent of the sample. Gender (male) and age group (young) were strong predictors for problematic use of video games. A higher proportion of high frequency compared with low frequency players preferred massively multiplayer online role-playing games, although the majority of high frequency players preferred other game types. Problematic use of video games was associated with lower scores on life satisfaction and with elevated levels of anxiety and depression. Video game use was not associated with reported amount of physical exercise.     

Emotional intelligence: The MSCEIT from the perspective of generalizability theory

The Mayer, Salovey, & Caruso Emotional Intelligence Test (MSCEIT) has been reported to provide reliable scores for the four-branch ability model of emotional intelligence [Mayer, J. D., Salovey, P., & Caruso, D. R. (2002). Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT). User's manual. Toronto, Canada: Multi-Health Systems]. However, no studies have yet been reported that have carried out a comprehensive analysis of reliability of scores from MSCEIT, taking into account the different conceptual features of the multifacet measurement design. Results from generalizability analyses of scores from 111 Norwegian executives' responses on the Norwegian version of MSCEIT show that scores reflect considerable amounts of measurement error. Ability scores from Perceiving Emotions are multidimensional, reflecting different types of emotion and the presence or absence of rated emotions in the stimuli. Generalizability (reliability) coefficients for scores from Perceiving Emotions, Facilitating Thought, Understanding Emotion, and Managing Emotions were estimated to .71, .37, .50, and .46, respectively, which is substantially lower than reported in previous studies. The low estimated generalizability coefficients suggest that the scores may not generalize well to intended domains, and the validity of some of the scores may be questioned.     

Processing of haptic texture information over sequential exploration movements

Where textures are defined by repetitive small spatial structures, exploration covering a greater extent will lead to signal repetition. We investigated how sensory estimates derived from these signals are integrated. In Experiment 1, participants stroked with the index finger one to eight times across two virtual gratings. Half of the participants discriminated according to ridge amplitude, the other half according to ridge spatial period. In both tasks, just noticeable differences (JNDs) decreased with an increasing number of strokes. Those gains from additional exploration were more than three times smaller than predicted for optimal observers who have access to equally reliable, and therefore equally weighted, estimates for the entire exploration. We assume that the sequential nature of the exploration leads to memory decay of sensory estimates. Thus, participants compare an overall estimate of the first stimulus, which is affected by memory decay, to stroke-specific estimates during the exploration of the second stimulus. This was tested in Experiments 2 and 3. The spatial period of one stroke across either the first or second of two sequentially presented gratings was slightly discrepant from periods in all other strokes. This allowed calculating weights of stroke-specific estimates in the overall percept. As predicted, weights were approximately equal for all strokes in the first stimulus, while weights decreased during the exploration of the second stimulus. A quantitative Kalman filter model of our assumptions was consistent with the data. Hence, our results support an optimal integration model for sequential information given that memory decay affects comparison processes.     

Determination of the Burgers vector of dislocations in icosahedral quasicrystals by a high-resolution lattice-fringe technique

A technique for the determination of the full six-dimensional Burgers vector characterizing a dislocation in an icosahedral quasicrystal is presented. It is based on the lattice-fringe analysis of two high-resolution transmission electron microscopy images taken at two different sample orientations. As an example we present the analysis of a dislocation in a bent icosahedral Al-Pd-Mn quasicrystal. We obtained a Burgers vector B = A₀[-2,0,3,-2,3,0] where A₀ = 0.645nm is the six-dimensional hyperlattice constant. This result is consistent with previous results obtained by diffraction contrast analysis and convergent-beam electron diffraction techniques.     

Neuropsychological function in a group of patients 25 years after sustaining minor head injuries as children and adolescents

Previous studies suggest that neuropsychological impairment following mild to moderate pediatric head injury may become persistent and interrupt the normal course of intellectual development. In this study 45 subjects were assessed with a standardized neuropsychological test battery 25 years after sustaining mild to moderate head injury as children. Although the group scores in the normal range, significant relations between head injury severity and current neuropsychological function were found. The most important predictor of poor outcome was length of PTA at injury, EEG pathology, and loss of consciousness at injury. No significant influence of pre- and post-injury risk factors on current neuropsychological function was evident. The findings support the view that complicated mild and moderate paediatric head injury may heighten the risk of developing subtle neuropsychological problems later in life.     

The interplay of personality and negative comments about appearance in predicting body image

This study investigates how personality traits in combination with frequency of and emotional reaction to negative comments about appearance while growing up are related to appearance evaluation and orientation among adult women. Nine hundred and seven participants from a representative sample of Norwegian women aged 22–55, answered questions measuring body image, personality (Big Five), and history of experiencing negative comments about appearance. Results indicated that only emotional reaction to negative comments about appearance significantly predicted both appearance evaluation and orientation, while frequency of negative comments did not. Being extrovert predicted more positive appearance evaluation and being more appearance oriented than being introvert. Scoring high on neuroticism was related to negative appearance evaluation and high appearance orientation. The findings demonstrate the importance of differentiating between the frequency and the emotional impact of teasing as well as including personality traits when studying body image.     

Unknowability and Incarnation: Creation and Christology as Philosophy of Science in the Work of Nicholas Cusanus

Nicholas Cusanus contributed to the development of modern science through a philosophy of unknowability, according to which the fact that the world makes sense is interpreted as a gift from the Creator, and the fact that it makes sense for the human is seen as an implication of the human being created in God's image. As placed on the crossroads between the eternal and the finite, the human is thus confronted with the challenge of discerning the manifestations of the infinite in the finite. This challenge was realized by Christ, who is thus epistemologically relevant as a demonstration of the possibility of adequate human knowledge through the coincidence of the human difference from and union with God.     

Antecedents and outcomes of intervention program participation and task priority change among school psychology counselors: A latent variable growth framework

A three-year national intervention program introduced into the School Psychology Service (SPS) in Norway with the aim of increasing systemic level work among SP counselors was investigated. Latent variable growth models based on longitudinal data from 195 SP counselors gave no significant mean level change in systemic level work. This concurred with GLM analyses based on data from a sample of 20 schools. However, retrospective self-reported significant positive mean level change for systemic level work was detected among the SP counselors. Intervention program participation was associated with individual change in systemic level work. Self-efficacy beliefs about systemic level work, and school-related etiology beliefs predicted individual change to a certain degree. Comparison of two rival models gave no support for a hypothesized interaction among intervention program participation and beliefs in their effects on systemic level work. Open-ended questions indicated that individual level workload and the perceived expectations from the schools may have concern for a successful effect of the intervention program in addition to the hypothesized ones. Individual change in systemic level work was positively associated with individual change in job satisfaction.
