Resilience to adult psychopathology following childhood maltreatment: evidence from a community sample

OBJECTIVE: Child abuse is an important risk for adult psychiatric morbidity. However, not all maltreated children experience mental health problems as adults. The aims of the present study were to address the extent of resilience to adult psychopathology in a representative community sample, and to explore predictors of a good prognosis. METHODS: Data are drawn from a follow-up of the Isle of Wight study, an epidemiological sample assessed in adolescence and at midlife. Ratings of psychiatric disorder, peer relationships and family functioning were made in adolescence; adult assessments included a lifetime psychiatric history, personality and social functioning assessments, and retrospective reports of childhood sexual and physical abuse. RESULTS: Ten percent of individuals reported repeated or severe physical or sexual abuse in childhood. Prospective measures revealed increased rates of adolescent psychiatric disorders in this group. Rates of adult psychopathology were also high. A substantial minority of abused individuals reported no mental health problems in adult life. Resilience of this kind was related to perceived parental care, adolescent peer relationships, the quality of adult love relationships, and personality style. CONCLUSION: Good quality relationships across childhood, adolescence and adulthood appear especially important for adult psychological well being in the context of childhood abuse.     

A high resolution laser scanning model of the Roman theater in Pinara,Turkey – comparison to previous measurements and search for the causes of damage

The archaeological site Pinara, southwest Turkey, which includes several remarkable objects of cultural heritage, has been the focus of several previous archaeoseismic studies. One of these examined the setting of the Roman theater in the east of Pinara by a lidar survey. A gross inclination of the stone rows of the auditorium of 0.81° towards N 314°E was interpreted as a consequence of recent coseismic tectonic movements. A new survey of the theater with a terrestrial phase laser scanner is the basis for a model with 15 times higher resolution and 28 times more data points. Parallel to the fieldwork in this study, the process and accuracy of the leveling of the 3D point clouds produced by the scanner was tested in a series of experiments. Based on the orientation of the blocks forming the seats of the theater, we suggest six sections with changing average inclination of the seats and a fault line separating a northern and a southern section. While the previously found overall inclination of the auditorium is confirmed by the new model and the dip direction agrees, the inclination is 0.58° compared to previously determined 0.81°. The almost perfect increase of inclination with the height of the first 10 entire seating rows and the nearly constant inclination from row 11 onward, makes systematic measurement errors during the construction a possible cause. This is an alternative scenario to the interpretation of a coseismic displacement of the conglomerate block on which the theater was built.

Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.     

Scientific teams and institutional collaborations: Evidence from U.S. universities, 1981-1999

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 top U.S. research universities over the period 1981-1999. The top 110 account for a large share of published basic research conducted in the U.S. during this time.We measure team size by the number of authors on a scientific paper. Using this measure we find that team size increases by 50% over the 19-year period. We supplement team size with measures of domestic and foreign institutional collaborations, which capture the geographic dispersion of team workers. The time series evidence suggests that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s. This acceleration suggests a sharp decline in the cost of collaboration. Our hypothesis is that the decline is due to the deployment of the National Science Foundation's NSFNET and its connection to networks in Europe and Japan after 1987.Using a panel of top university departments we also find that private universities and departments whose scientists have earned prestigious awards participate in larger teams, as do departments that have larger amounts of federal funding. Placement of former graduate students is a key determinant of institutional collaborations, especially collaborations with firms and with foreign scientific institutions. Finally, the evidence suggests that scientific output and influence increase with team size and that influence rises along with institutional collaborations. Since increasing team size implies an increase in the division of labor, these results suggest that scientific productivity increases with the scientific division of labor.     

What do second-order judgments tell us about low-performing students’ metacognitive awareness?

According to the unskilled and unaware effect (Kruger and Dunning 1999), low-performing students tend to overestimate their performance. Differentiating the assessment of metacognitive judgments into performance judgments (PJs) and second-order judgments (SOJs), PJs of low-performing students tend to be inflated, while their SOJs are usually lower than those of high-performing students (Händel and Fritzsche 2016; Miller and Geraci 2011). This suggests some level of awareness. The present study investigated whether low-performers’ lower SOJs actually indicate metacognitive awareness. We studied SOJs after adequate and inadequate PJs, and investigated whether low-performers’ lower SOJs are made by default or whether their lower SOJs differ in a similar magnitude compared to those of high-performers (indicating metacognitive awareness). We address this issue by disentangling student and item effects via generalized linear mixed models. Reanalyzing the data of Händel and Fritzsche (2016) from N?=?116 students, we found that SOJs depended on the students who provided the SOJ and on the items on which the SOJ was made. Overall, SOJs depended on the PJs and on the interaction of performance and PJs, but not on the performance itself. Separate analyses for students of different performance levels revealed that low-performing students showed less awareness, indicated by a non-significant interaction effect of performance and PJs. Thus, it takes mixed models to tell the whole story of low-performing students’ lower SOJs.     

Investigations of Temperament at Three to Seven Years: The Children''s Behavior Questionnaire

This article reviews evidence on the reliability and validity of the Children's Behavior Questionnaire (CBQ), and presents CBQ data on the structure of temperament in childhood. The CBQ is a caregiver report measure designed to provide a detailed assessment of temperament in children 3 to 7 years of age. Individual differences are assessed on 15 primary temperament characteristics: Positive Anticipation, Smiling/Laughter, High Intensity Pleasure, Activity Level, Impulsivity, Shyness, Discomfort, Fear, Anger/Frustration, Sadness, Soothability, Inhibitory Control, Attentional Focusing, Low Intensity Pleasure, and Perceptual Sensitivity. Factor analyses of CBQ scales reliably recover a three-factor solution indicating three broad dimensions of temperament: Extraversion/Surgency, Negative Affectivity, and Effortful Control. This three-factor solution also appears to be reliably recovered in ratings of children in other cultures (e.g., China and Japan). Evidence for convergent validity derives from confirmation of hypothesized relations between temperament and socialization-relevant traits. In addition, parental agreement on CBQ ratings is substantial. The CBQ scales demonstrate adequate internal consistency, and may be used in studies requiring a highly differentiated yet integrated measure of temperament for children in this age range.
